Game Recap: Baseball | 3/11/2025 11:39:00 AM | Tyler Woolbright
-- Limited free passes and plenty of multi-hit performances put North Park Baseball back in the win column on Tuesday morning
earning their first mercy rule win of the season
The Vikings had plenty of run support early
putting seven runners home through the first two innings of play
A wild pitch would bring him home for the lone run in the first inning
North Park starting pitcher, senior left hander Brett Ravitz
allowing a pair of runs in the top of the second on a misplayed bunt and RBI double
the Vikings would pile on in their half of the inning
The Vikings banged out six runs on five hits
taking advantage of three free passes by the Mariners' starting pitcher to swiftly establish a 7-2 lead
and tallied five singles to keep things moving
A scoreless third inning gave way to an interesting fourth, where three of five hits went for extra bases, slimming North Park's lead to 7-6. Junior right hander Zach Price relieved Ravitz in the fourth and worked to establish his footing to keep NPU ahead
The Vikings were blanked in the fourth inning but scored runs in all four of their proceeding trips to the plate
including a three-run eighth that was capped by Kawakami's walkoff
Price found his groove after that fourth inning
securing his first win of the season with four innings pitched
Sophomore catcher Reyn Matsuzaki led the Vikings with a 4-for-5 day at the plate
cracking a pair of doubles and scoring twice
Kawakami, Greenwood, and junior right fielder Joe Perona all had three-hit days
Every Viking starter reached base in the win
as Perona and DiVito crossed the plate three times each
Greenwood led NPU with four RBI in his 3-for-4 day
building on an already impressive freshman campaign
Mitchell's Savier Paige led the Mariners with a 3-for-4 day at the plate
North Park (2-9) concludes their Florida trip tomorrow
against the Western New England University Golden Bears (4-3)
First pitch at Northeast Regional Park is set for 9:00 AM ET

2025 as they embark on their "31 Flavours Tour" to celebrate their 31st year
The evening will also include opening performances from locals
the San Francisco band Deerhoof has cemented their place as one of indie music's most influential bands with their unruly and anarchic creative impulse
The mercurial rockers—consisting of founding drummer Greg Saunier
and guitarists John Dieterich and Ed Rodriguez—come to Pioneer Works fresh off the release of their 2023 album Miracle-Level
sung entirely in Satomi Matsuzaki’s native Japanese
For a band that seems to thrive on collapse
it’s simply amazing that this American-Japanese quartet is now celebrating their 31st year
Though Deerhoof long ago established itself as one of the greatest rock groups ever to stride the earth—and if you think that’s hyperbole
you haven’t seen them live—the furiously inventive quartet releases new albums on the schedule of a young band still hungry for its first break
Each one discovers some previously unknown combination of candy-coated hard-rock riffs and free-jazz percussive freakouts
sideways J-pop hooks and fearsome dissonance
trenchant social commentary and surrealist humor
Fronting it all is Satomi Matsuzaki’s inimitable alto
whose plainspoken calm can seem strangely outside of the band’s maelstrom
carrying an implicit note of defiant optimism in their refusal to bow to convention or received wisdom
Body Meat embarks on a multi-dimensional world-building endeavor
partly influenced by hours spent playing games like ‘Elden Ring’ and ‘Nier Automata,’ drawing inspiration from their expansive storytelling and gameplay
Taylor imagines each song as its own distinct ‘level,’ and himself as the avatar moving through an immersive storyline
iiisa is the solo project of NYC-based vocalist and improviser-composer, isabel crespo pardo
Their intimate songs emerge from warm sonic landscapes filled with familial chatter and field recordings from their home in Costa Rica
With “a gloriously improvised heart,” they transform opaque memories into powerful ephemera in hopes of offering solace
Pioneer Works music programming is made possible in-part by New Belgium Brewing Company

Matsuzaki masterclass sinks title contenders (Shimizu S-pulse vs Avispa Fukuoka analysis) | OneFootballSportsEye
Shimizu S-pulse Stun League High-flyers Avispa FukuokaClinical Shimizu End Fukuoka's Unbeaten Run with 3-1 VictoryShimizu S-pulse delivered a masterclass in efficiency as they secured a 3-1 victory over title-chasing Avispa Fukuoka at the IAI Stadium Nihondaira
ending the visitors' seven-match unbeaten streak
The hosts wasted no time making their mark
with Kai Matsuzaki firing them ahead after just three minutes
converting from Capixaba's excellent build-up play
Fukuoka responded quickly when Tomoya Miki converted from the penalty spot in the ninth minute after Kazuki Fujimoto was fouled in the box
Despite Fukuoka dominating possession (62%)
it was Shimizu who struck decisively before half-time
Brazilian midfielder Matheus Bueno restored their lead with a header from Matsuzaki's corner in the second minute of first-half stoppage time
before Matsuzaki claimed his second goal three minutes later following Kengo Kitazume's cross
This victory marks Shimizu's second consecutive league win - a first for them this season - following their dramatic comeback against Yokohama F
Marinos last week when they overturned a two-goal deficit to win 3-2
earning an 8.7 match rating with two goals and an assist
The forward has been in scintillating form
proving instrumental in Shimizu's recent upturn in results
"We showed great character today," said Shimizu manager Akiba Tadahiro
"The team is building momentum and showing real unity
especially considering our tight schedule and injury challenges."
winning 9 of 13 duels while contributing both defensively and in attack
while January signing Matheus Bueno continued to justify his acquisition with a crucial goal
this defeat marks their first loss in eight matches and sees them surrender top spot in the J1 League to Kyoto Sanga
Despite creating more chances (13 shots to Shimizu's 7)
Kim Myung Hwi's side lacked the clinical edge that has defined their impressive start to the campaign
who had conceded just twice in their previous seven matches
shipped three goals in a single game for the first time this season
exposing defensive vulnerabilities that had previously been well-hidden
Miki's penalty was their only reward from a match where they dominated the ball but struggled to convert possession into meaningful opportunities
with just three shots on target despite their territorial advantage
Shimizu's 3-4-2-1 formation proved effective against Fukuoka's possession-based 4-2-3-1 system
The hosts' compact defensive shape and rapid transitions repeatedly caught Fukuoka off guard
while set-pieces proved decisive with Bueno's header coming directly from a corner
The match statistics tell the story of contrasting approaches: Fukuoka completed 327 of 428 passes (76% accuracy) compared to Shimizu's 182 from 269 (68%)
but the hosts' direct approach yielded more dangerous opportunities
Both managers utilised their full complement of substitutions in the second half
with Fukuoka's Yu Hashimoto making a positive impact off the bench

COLUMBUS -- The NHL will go all-in on the bitter rivalry between Ohio State and Michigan when the 2025 Navy Federal Credit Union NHL Stadium Series is held at Ohio Stadium on March 1
learned quickly how the matchup of the Columbus Blue Jackets
will evoke emotions usually associated between the two neighboring schools
He and his staff arrived two days prior to the football game between Ohio State and Marshall on Saturday to go over planning and coordination at the 102-year-old stadium
and we've learned how much people want to beat a team from up in Michigan as well
There's been a lot of that there," Matsuzaki said
"We've heard about the crossing out the M's on campus and things like that and somebody mentioned to me about crossing out D's for our game
It's a tradition the week before the annual Michigan football game to cross out all the M's on campus signs and buildings
you never say "Michigan." It's always "That Team Up North."
Matsuzaki can envision that type of environment for the Blue Jackets and Red Wings game considering it's about a three-hour drive from Detroit
but the fact that Michigan Stadium in Ann Arbor had 105,491 for the Winter Classic between the Red Wings and Toronto Maple Leafs on Jan
Its capacity is listed as 102,780 for football with the largest crowd being 110,045 on Nov
and we were north of 100,000 in that other stadium I was just talking about (Michigan)
I know there's going to be hope to get up there for this one," Matsuzaki said
Blue Jackets to host Stadium Series March 1
Tickets go on sale to the general public on Oct
Blue Jackets defenseman Jack Johnson played in the 2019 Stadium Series for the Pittsburgh Penguins at the Philadelphia Flyers in Lincoln Financial Field
home of the Philadelphia Eagles of the NFL
It's definitely a game you look forward to on the schedule
Johnson is well-versed in the Ohio State-Michigan rivalry in any sport having played for Michigan (2005-07) and now living in Columbus
"Playing at one of the iconic football stadiums in the country
in college football is a cool thing," he said
The Blue Jackets-Red Wings rivalry hasn't yet reached the level of the football rivalry
with only one Stanley Cup Series between the teams
the 2009 Western Conference Quarterfinals won by Detroit in four games
The Red Wings lead the regular-season series 65-31-15 with one tie
Matsuzaki said the NHL is interested in incorporating some pregame football traditions such as the "skull session," where the Ohio State marching band holds a pep rally in St
John Arena across the street from Ohio Stadium
"We had a whole group here watching the players walk in (to the stadium) and the skull session and seeing how we can lean into that and lean into the traditions," he said
He also said the NHL is considering how best to honor Blue Jackets forward Johnny Gaudreau and his brother Matthew at the event
29 when they were struck by a car while riding bicycles in Salem County
"Our group is working on that right now," Matsuzaki
The rink will be placed between the 17-yard lines inside the numbers
but Blue Jackets defenseman Damon Severson had a vision of what to expect when he attended the Ohio State-Western Michigan game in Ohio Stadium on Sept
"We were up pretty high and just looking out and just kind of seeing how it was
and we're going to be the ones entertaining that night so it's really exciting.' I'm looking forward to it," he said

It's hard not to stare at the giant tulip poplar tree in Greenville's Hessie T
It's the tree she always admired while walking her dog Mochi
also home to gender reveal celebrations and people who curl up to read or paint
"We thought it was such a beautiful testament
but to all the relationships that exist today
where there's always going to be tough times
but you weather through it," Matsuzaki said
Her beloved park tree withstood Helene's damage
which brought down thousands of untold trees across the Upstate
trees often fell during the storm because of some underlying problem with the tree
a Clemson University extension specialist in horticulture and arboriculture
"Many of them were predisposed to some defect
and with the rains prior to Helene and during
that compromised these trees," Polomski said
Trees that are still standing - especially if they are near homes or cars - could be ripe for a basic half-hour homeowner inspection (he has a 7-point guide) but if anything is amiss
a professional arborist should be called in
Many of the trees that fell in the city of Greenville were water oaks that were at or near the end of their under-100-year life anyway
formerly the long-time executive director of Trees Upstate
who was authorized to discuss the organization's response to Helene
The water oaks along several major Greenville streets have long been identified as potential issues
said the giant red-dirt-encrusted root balls
seen all across the Upstate since the storm
The tree tends to have a saucer-shaped root ball that doesn't go much deeper than two feet
"The primary tree that went down was white oak and white oak has always been the sturdiest tree in the forest," he said
"They don't go deep down like a tap root like your pines and nut trees like pecan and hickory do."
The white oak roots themselves can go twice as wide as the tree is tall
Ashmore, a famed hater of the Bradford pear tree
said that the irony of the storm is that the normally sturdy white oaks fell while the normally-prone-to-breaking Bradford pears escaped the storm virtually unharmed
"I've only heard of one Bradford pear falling," Ashmore said
That's because the Bradford pear's weakness is its branches
Earlier this year, Greenville County released a study that found a 38% tree canopy over the county
Plans to boost that to as high as 46% would require protecting existing trees and planting new ones
mature trees were seen to be at risk of development
The study recommended optimizing stormwater designs and planting trees in flat areas to reforest
which could help to mitigate future storms
Teachey said the canopy is so large in Greenville County that it is unlikely to decrease
even though there's lots of trees on the ground
There may be a noticeable dip in the city's canopy coverage
but likely not more than a percentage point or two
"The loss of trees in the city is tragic now and people are dealing with a lot of loss," Teachey said
calling up the tree workers and returning to replanting trees."
She said donors and staff at Trees Upstate had trees fall on their homes during the storm
Polomski worries that people will start hating trees and withdrawing from plans to boost the trees
especially since so many need to be replaced now
Polomski said the fallen trees could pose challenges in the near future
providing fuel for potential wildfires and leading to discussions about proscribed burns or other fire control measures
we're seeing how critical that is out West," he said
But the trees in Greenville will continue to be important
the city had approved a policy calling for replacing trees that were removed or fell down from public right-of-way areas
The city has also committed to planting 1,000 new trees a year
because replacing 100—and 200-year-old trees takes time
but DeWorken said he hopes the city will keep focusing on increasing the number of trees
It's too early to make any evaluations of the tree cover in the city of Greenville and the city's urban forester and his team are working on tree safety
"We know our tree canopy took a significant hit
But it's never too early to appreciate the trees
She previously lived in big cities like San Francisco and moved to Greenville about three years ago
That towering tulip poplar tree she adores
and was used traditionally by Native Americans to make canoes because it was so straight and large
Walking among the devastation of the trees in the park near her home on Monday morning
Matsuzaki said she is seeing the best of Greenville after the storm
We go on our daily walk and pass this big tree so many times
It's here and it's strong and it's been there for us and hopefully we can be there for it."

Ken MatsuzakiLarge plate, oribe glaze, N/APucker GallerySold Square plate
shino glazePucker GalleryHis choice to pursue originality is evident in viewing this recent collection
Matsuzaki’s departure from the wheel in order to develop a personalized handbuilding method opened the gates to a panoply of new shapes constructed with clay
Moving away from familiar glazes allowed for new color and texture palettes to emerge
and exploring different firing techniques brought versatility to his final results
these new ways of working bring an energetic
Matsuzaki’s process is the root of his work
equal measure of mindfulness and effort is given to each step of the unabating process required to produce a pot
and wedging (kneading) of the clay all are necessary prior to wheel throwing and handbuilding
It is common for works to crack or break as they go bone dry
Works that manage to survive the glazing process still must face the final gauntlet of the kiln
After working for six months to create a group of pots to fill his kiln
and cleanup of both the kiln and the final pieces
and fire collaborate to transform the works
Only those deemed worthy will move beyond the kiln
Works that do not meet Matsuzaki’s aesthetic standards are smashed and discarded over the shards of their predecessors
Ken’s discipline and respect for process is testimony to his true commitment as a ceramic artist.
A rounded vase with oribe glaze (MK877) is an example of process and exploration at work
(Oribe refers to a style of pottery produced in Japan beginning in the late sixteenth century
most identifiable for its use of a glassy and fluid copper green glaze.) When placed in the kiln
Its faceted edges allowed the glaze to behave like water
Where the clay is elevated and comes to a thin edge the glaze becomes translucent
showing the iron speckled stoneware through the green hue
As the clay returns to a uniform thickness
As fire and air currents swirled through the kiln and around the vase like a river
they carried with them fly ash to lightly dance on the surface encouraging electric blue waterfalls to form on the left side of the vase

yohen shino glazePucker GalleryA pair of plates (MK889 and MK890) are gorgeous examples of the versatility of Matsuzaki’s oribe glaze
coupled with the awesome potential of a highly successful wood firing
both handbuilt and wheel-thrown plates are notoriously difficult
During the making process they must dry slowly and evenly or they will warp and easily distort
open forms leave the surface susceptible to contaminants and kiln debris
Matsuzaki’s plates are almost anomalies of the ceramic world
the oribe glaze flows from light to deep green
transitioning to pools of blue that range in color from the night sky to Caribbean waters
self-contained worlds when visually and physically held
Run your fingers across the smooth shino surface on the top of a tea bowl (chawan
then follow to where the smoothness meets Matsuzaki’s thick
white feldspar glaze resembling snowcapped hillsides
Move further along the piece to find small pockets of bare clay
like patches of desert laying bare the stoneware’s grit
Such results are certainly not achieved overnight – and often not in one’s life time
Curiosity leads to understanding materials
determination allows for overcoming obstacles
Passion is the inferno that forges all these qualities into one and Ken Matsuzaki is passionate

As anime and manga are beginning to receive more and more live-action adaptations
Japanese actor Yuki Matsuzaki believes it should be a requirement that every such production update their source materials in order to appeal to “modern values”
RELATED: ‘Lycoris Recoil’ Season Finale Writer Attacked By Mob Of Angry Shippers Over Episode’s Lack Of Lesbian Ending
the actor – whose Western filmography includes roles as Garheng in Pirates of the Caribbean: On Stranger Tides
and Miyamoto Usagi in Teenage Mutant Ninja Turtles (2012), blew up Japanese Twitter with a discussion of the upcoming live-action adaptation of Satoru Noda’s best selling manga
Retweeting a previous thread of his from April 2018 wherein he urged the film’s producers to cast a race-accurate Ainu actor in the role of Asirpa
Matsuzaki added to his initial thoughts (via DeepL) “Not only [this casting issue]
but the homophobia/transphobia in this work is also quite bad.”
“The whole world will be turned off if we don’t ‘update our awareness’ when making a live-action manga with such a ‘prejudiced minority image’ drawn many years ago,” he then declared.”Let’s stop mass-producing live-action works that can’t be shown to the world for good.”
As an example of Golden Kamuy’s “prejudiced minority depictions”
Matsuzaki pointed to the relationship between Yakuza members Kiichirou Wakayama and Tatsuya Nakazawa and described their portrayal as “being the stereotypical gay couple who is treated as a ‘joke’ just for ‘being gay’.”
“And every time they show affection for each other
the ‘main character who looks at them coldly’ is inserted to emphasize the impression that they are ‘strange people’ to the readers,” he further argued

“The ‘clownish treatment’ of this gay couple is so thorough that a ‘fake emotional panel’ appears in a spread in the scene where they fall together in an attempt to save their lover.”
he ‘reveals’ that he is ‘not moved’ and consumes ‘the existence of gay people’ as a ‘joke’,” he said
“If such “discriminatory depictions of minorities” are reproduced as ‘jokes’ in live-action films … and if the audience laughs at the ‘jokes’ … everyone in that theater gets the message that being a minority is a joke and that it is okay to laugh.”
“In other words,” he explained
“it encourages discrimination.”
“Manga depicting minorities that have been published for a long time often contain discriminatory representations of minorities according to modern values such as [Golden Kamuy],” he ultimately noted
“If such ‘discriminatory representations’ are reproduced in live-action films
it may lead to new prejudice and discrimination against minorities in the ‘real world’.”

Japanese manga fans – particularly those of Golden Kamuy – did not share his sentiment
they soon responded to the actor with criticism of their own
he returned to Twitter to express disbelief that said fans did not take kindly to his disparaging virtue signaling
“I asked Japanese Golden Kamuy manga/anime fans to publicly call for Ainu representation in the live-action film currently being made,” exclaimed Matsuzaki
“They say it doesn’t matter as long as the Ainu girl (Asirpa) is portrayed funny,” he lamented
“I can’t believe I have to teach people what minority representation is in 2022 … And NOT the ‘importance’ of it …they don’t even know the CONCEPT of minority representation,” he continued protesting
Japan is a country with ZERO minority representation in media.”
RELATED: Koei Tecmo Likely To Censor ‘Fatal Frame: Mask Of The Lunar Eclipse’ Remaster Across All Platforms
“And because there’s no minority representation in Japanese movies/TV series
Japanese people are misled to believe that Japan is ‘a homogenous country,'” the actor further decried
Japan is… and HAS BEEN… a DIVERSE country
It’s just its true diversity hasn’t been represented in media.”
“Japanese people are SO FAR BEHIND when it comes to the concept of minority representation in media,” Matsuzaki argued
“Even after I pointed out these scenes👇 in Gold Kamuy are homophobic
they still couldn’t get what’s so homophobic about
RELATED: ‘Marvel’s Spider-Man Remastered’ Mod Replacing LGBT Pride Flags With American Flags Banned By Nexus Mods
and the lack of minority representations in media have real-life consequences,” he claimed
many mixed-race Japanese are treated as “foreigners” because they’re portrayed as ‘not Japanese’ on media all the time
Attempting to rally his followers to his cause
“I know Japanese entertainment industry responds only when there’s enough public pressure to do the right thing
Tell @SHUEISHA_PR what YOU want to see in Golden Kamuy film.”
“Do you want to see Ainu representation?” he asked
“Or you just want silly faces?”
the actor expressed disgust at the “current state of the Japanese Golden Kamuy fandom” based solely on the fact that they disagreed with his fixation on Asirpa’s potential Ainu casting
In an attempt to justify his disdain for the fandom
only a mere 3.7% considered ethnicity to be an important factor in to be an important issue
97.3% believed that the film’s producers should cast whomever they want in the role
the live-action Golden Kamuy film has yet to receive an official release date

We talked about Yukiyo's favourite undiscovered destinations in Kamakura and areas
Japan and moved to New York City at the age of 15 when my father’s job took my family there
I returned to Japan after attending high school in New York and studying piano at the Juilliard School
and graduated with a Bachelor of Arts degree from International Christian University (ICU)
I found work as an HR specialist with foreign affiliated companies
After marrying an American translator and having two kids
and receptionist at a long-established resort hotel owned by my in-laws in Vermont
where I was involved in all aspects of management
including the implementation of a new reservation system
This was my first experience with destination tourism
and the moment I realized that fostering harmony between locals
and the organisation was essential to creating a sustainable destination
I came back with my family to Japan again in 2012, this time to Kamakura, where I established Kamakura Mind in 2018: a place where people can experience Japanese culture
with the aim of "communicating the beauty of Japanese culture beyond the language barrier." In partnership with about 20+ instructors
I provide programs for foreigners in unique locations such as traditional Japanese houses
using my experiences in both Japan and the United States
As a place where you can experience Japanese culture in English
Kamakura Mind has been featured in Tokyo Weekender
the oldest English-language information media for foreigners in Japan
exclusive tours focusing on "Zen Culture in Kamakura"
the city of Kamakura is famous for its natural setting
with mountains on three sides and ocean on the other
you can see remnants of the ancient samurai capital
and hear the echoes of Zen Buddhism’s rise in the ringing of the temple bells
Thanks to Kamakura being one of the towns spared from bombing in WW2
there are many old houses and traditional streets remaining
I’ve discovered many more charms of the town by just walking around and talking to people — artists
Meeting the local artisans and cultural figures made me realize that Kamakura isn’t all about the big temples and big Buddha
There’s a lot this small city has to offer
and I’m grateful to be able to share some of the charms of Kamakura via Kamakura Mind

We have developed a method for the three-dimensional (3D) printing of continuous fiber-reinforced thermoplastics based on fused-deposition modeling
The technique enables direct 3D fabrication without the use of molds and may become the standard next-generation composite fabrication methodology
A thermoplastic filament and continuous fibers were separately supplied to the 3D printer and the fibers were impregnated with the filament within the heated nozzle of the printer immediately before printing
Polylactic acid was used as the matrix while carbon fibers
The thermoplastics reinforced with unidirectional jute fibers were examples of plant-sourced composites; those reinforced with unidirectional carbon fiber showed mechanical properties superior to those of both the jute-reinforced and unreinforced thermoplastics
Continuous fiber reinforcement improved the tensile strength of the printed composites relative to the values shown by conventional 3D-printed polymer-based composites
3D printing has primarily been used for trial products or toys
without application to the manufacture of structural components for aerospace or automotive products
Broadening the applicability of 3D printing to obtain mechanically strong components for aerospace and automotive structures is a major goal of industrial fabrication
the conventional fabrication methods for composites require expensive facilities and equipment
such as autoclaves and complex rigid molds
hindering the wide application of composites
Realizing the 3D printing of composites could supplant the conventional laborious manufacturing of composites
thus becoming the next-generation standard of composite fabrication (or “Composites 2.0”)
The test specimens were printed along the longitudinal direction
parallel to the direction of fiber alignment
The mechanical properties of the 3D-printed continuous fiber composites were measured by tensile testing and compared with the performance of neat PLA resin
(a) Schematic of the 3D printer head used to produce continuous FRTPs using in-nozzle impregnation based on FDM
(b) Continuous fiber reinforcements used for 3D printing
(c) Photograph of the 3D printing of a CFRTP
The 3D printer for obtaining continuous-fiber composites was developed by modifying the printer head of the commercially available FDM 3D printer Blade-1 printer with a preheating system. This modified printer was used to print carbon fiber-reinforced thermoplastics (CFRTPs), as shown in supplementary Fig. 1
A modified FlashForge printer was used to print jute fiber-reinforced thermoplastic (JFRTP) green composites (no preheating was used for the JFRTPs to prevent the degradation of the jute fibers)
Unmodified PLA was also printed using the Blade-1 printer
as a comparison to measure the mechanical enhancement achieved by reinforcing the resin with continuous fibers
the printer head moves along the x and z directions
whereas the hot table moves in the y direction to enable 3D fabrication
The diameter of the resin filament is 1.85 mm
exceeding the 1.4 mm diameter of the nozzle
the molten resin inside the nozzle is pushed out from the solid resin; the pressure facilitates the impregnation of molten resin into the fiber bundles in the nozzle
Since a large nozzle diameter was used in this pilot study to prevent clogging of the reinforcing fibers
3D-printed (a) CFRTP and (b) dumbbell-shaped JFRTP tensile test specimens
(c) Cross-section and (d) magnified cross-section of the CFRTP specimen
while dumbbell-shaped JFRTP specimens were fabricated with a traversable CAD path
The ply created by this path was layered in the z-direction four times for a total specimen thickness of ~4 mm
The carbon or jute fibers were aligned along the longitudinal direction
which was chosen as the loading direction and no fibers were aligned in the transverse (y) or thickness (z) directions in the gage region of the tensile test specimens
the mechanical properties of the tensile specimen are orthotropic and maximized along the loading direction
Aligning the reinforcing fibers with the transverse and thickness directions would also be possible; however
the aspect of alignment is beyond the scope of this study and related experiments are not presented here
Neat PLA tensile specimens were also fabricated to demonstrate the reinforcing effect achieved by the continuous carbon or jute fibers
CFRTP and JFRTP were used for the tensile tests
Stress-strain curves of PLA, unidirectional CFRTP and unidirectional JFRTP specimens fabricated by 3D printing.
(b) tensile strength and (c) tensile strain-to-failure of specimens fabricated by 3D printing
The tensile strength of JFRTP is not improved significantly compared to that of CFRTP
the tensile modulus and strength are 5.11 (±0.41) GPa and 57.1 (±5.33) MPa
corresponding to 157% and 134% of those shown by the PLA specimen
The tensile modulus of JFRTP is obtained from the tensile strain in the range of 0.05% to 0.25%
although the tangential modulus decreases with increased stress above this strain range
The decrease in tangential modulus and the lack of improvement in the tensile strength can be attributed to the degradation of fiber-resin interactions with increased applied stress
no tension was applied to the jute fiber when the yarn was fed to the nozzle
This led to a non-uniform configuration of the twisted jute yarn fibers
which may have created weak points in the printed filament
When using a twisted yarn as reinforcement
an appropriate tension and torsional moment must be applied to the yarn during 3D printing
which would assist the uniform molding of the FRTP

JFRTP and PLA specimens using a universal tester (AG-IS 150 kN
Shimadzu) at a crosshead speed of 1.0 mm/min
A strain gage was attached to the specimen surface to measure strain
The specimen configuration was rectangular with PLA end tabs for the CFRTP
while the JFRTP and PLA specimens were dumbbell-shaped without end tabs
The shoulder portions of the specimen were clamped directly by the wedge grips of the tester and a tensile load was applied uniaxially to the specimen

For its latest specialty offering, Japanese retailer and label BEAMS enlists Matsuzaki Bokken Workshop for a bespoke red oak wooden sword
which translates to Matsuzaki Bokken Workshop
is a small family business founded by Matsuzaki Yoshinori who began manufacturing Bokken swords used for Kendo training in 1968
he’s a second-generation master who runs the shop with his son and wife
This particular sword is made by hand from the red oaks of Southern Kyushu
and in addition to being a combat-ready sparring weapon
also serves as a standout interior ornament
A “Beams Japan” logo can be seen printed in black on the base of the handle
GeekCraft Expo founders Daniel Way and Kim Matsuzaki are eager to bring their “Etsy meets Comic Con” to Hawai‘i Convention Center Oct
What happens when creativity meets connection
actually: A winning relationship and a successful national event that is making its first appearance in Hawai‘i this month
the brainchild of comic book and videogame writer Daniel Way and former Ubisoft senior community manager Kim Matsuzaki
you’re all in on something that you love,” Matsuzaki says
the story of how GeekCraft came to be is a little more interesting when one understands what its quirky and talented founders bring to the table
it all began with a love of telling stories
so I always had some goofy anecdote about something I did or saw,” he remembers
he befriended a comic book shop owner who recommended he start turning his stories into comics
Hamming it up for the camera are Daniel Way
They’re like power fantasies or people dressing up in silly costumes,” Way laughs
He gave Way some non-mainstream titles to try out
Way was immediately captivated by the depth and range of storytelling involved
He then was fortunate enough to receive a Xeric Foundation grant that enabled him to get it published
He brought his book to the Small Press Expo in Maryland
he got a call from Marvel editor Axel Alonso
asking if he wanted to try his hand at writing Spider-Man
The couple’s work includes Way’s writings about several famous comic book heroes and their geeky collectible items for the upcoming GeekCraft Expo at Hawai‘i Convention Center
and he wasn’t interested in writing superhero comics
But Marvel was keen to get new voices and shake things up
so Alonso pursued Way until they came up with a story that would work (an entry in Spider-Man’s Tangled Web)
15 years passed — and Way made a name for himself
writing for characters as varied as The Incredible Hulk
“I was always trying to resurrect forgotten characters and take characters off the trash pile who had fallen off the cultural radar
It’s hard to believe that today when Deadpool has starred in two solo
But Deadpool was swirling in the toilet bowl
“I did my best to take a new approach
and it’s the Deadpool you see now: I kind of put him on that path.”
He chose to leave his exclusivity deal with Marvel and “jump in with both feet” into creating his own independent works again
Way teases that his next project has been “gestating” for a long time
where a mercenary of sorts devotes himself to rescuing unwilling mail-order brides
The Castle High School grad attended University of Hawai‘i at Mānoa
where she got a “safe” degree in information technology
“I was never passionate about it,” she says
she got in the habit of playing video games with friends after work
She eventually got restless and left Hawai‘i
Eventually, she found herself in the role of community manager for 1Up.com
‘I want to do the same thing I’m doing with my friends and get paid for it,'” Matsuzaki muses
to work for videogame publisher Ubisoft as senior community developer
where she was responsible for communicating updates between the development team and fans
working on titles like Assassin’s Creed and Far Cry 2
She later moved to Ubisoft affiliate Red Storm Entertainment
“The community is just frothing at the mouth for upcoming games
So I knew what the community wanted to hear
and got out of the videogame industry soon after
with an urge to focus on family (the couple have a 5-year-old daughter
and Jimmy “Jimmy Sparrow” Ishizaki
GeekCraft is what happens when you bring a master of creation with the queen of connection
and especially shopping for items that reflect her eclectic tastes
“Being geeks ourselves and going to a lot of conventions
It’s been two hours and I only found this one thing,'” Matsuzaki says
but it was just the handmade nerdy stuff from comic cons?” Way muses
the couple founded the first GeekCraft Expo in Madison
It has since expanded to cities as varied as Seattle
What sets GeekCraft apart from conventional craft fairs or even Artist Alleys within larger comic conventions is its laser-sharp focus
Every exhibitor that is there will have quality stuff,” Matsuzaki explains
and there won’t be a ton of the same thing
We’re not about exhibitors competing with each other for price
We want to make sure they complement each other.”
Some 40 vendors are expected to kick off the inaugural Hawai‘i event
with more than 2,000 people already pre-registered to attend as of press time
“You just have to come in and make it
the more nerdy — you may think this is too obscure
“There’s going to be someone who sees that and is so blown away that someone went that far with such an off-center idea that they just have to have it.”
GeekCraft Expo Hawai‘i runs from 10 a.m. to 5 p.m. Oct. 12, and 10 a.m.-4 p.m. Oct. 13 at Hawai‘i Convention Center. Admission is free with pre-registration via eventbrite.com; otherwise, it’s $5 at the door. For more information, visit geekcraftexpo.com
Daniel Way and Kim Matsuzaki have a vested interest in making sure GeekCraft Expo succeeds in Hawai‘i
three special events will take place at this expo
“We’ve invited some of our GeekCrafters from the mainland to send stuff over
so there will be an area of the show that will have handmade geeky stu~ that you haven’t seen on the island,” Way says
“That is a huge benefit for attendees because they’re getting new stuff.”
The hope is that the program will eventually work in reverse: Hawai‘i crafters can send their wares to the mainland GeekCraft Expos and get exposure and sales they otherwise would not have received
The second is a special section called Da Kine Indie Publishing
which will highlight local publications to get them attention and press from larger publishers who will be in attendance
“If it’s independently produced and published
Levin,” running from 5:30 to 8:30 p.m
Way’s agent and producer extraordinaire
Levin is the executive producer of TV series Preacher and The Boys
The co-founder of 1First Publishing will discuss what it takes to get a property from written page to the big screen
Tickets are $20 in advance on eventbrite.com
Pictured behind GeekCraft Expo founders Daniel Way and Kim Matsuzaki (on the cover) is an original mural by Jimmy “Jimmy Sparrow” Ishizaki — one of the expo’s 40 participating vendors
“I’m looking at every venue and opportunity I can get,” Ishizaki says
“This one (GeekCraft) is a brand-new one that popped onto my radar and seemed pretty cool to do
It’s important for them and me to be a part of — to help them get the word out
bring attention for the rest of the community that this is a new event they can do
There’s only like two big cons and a few mini-events spread out throughout the year
The longtime local con attendee is known for his cosplay prowess
owner of Snack Addicted (another local con stalwart who sells flavored beef jerky
including oxtail soup and yakiniku varieties)
I always want to support people who are doing what they are passionate about,” Fukumoto says
explaining that he was inspired to help Ishizaki after meeting him at a few conventions and getting to know him
“I have Jimmy’s stuff here (at the shop) because I want to help him.”
located in ‘Iolani Center next to PURVÉ Donut Shop
with one wall covered with different prints by local and mainland artists
Attendees will be able to find Ishizaki at GeekCraft Expo
and he’ll be bringing some of Fukumoto’s jerky with him to sell at his booth
Fukumoto promises there will be an exclusive flavor in honor of GeekCraft
Those who miss the expo but still want to see more of Ishizaki’s work can find it at Snack Addicted (1234 Kona St., second floor). For more information, find Ishizaki on social media or at jimmyxsparrow.com. Snack Addicted can be found at snackaddictedhi.com
EDMONTON -- The 2023 Tim Hortons NHL Heritage Classic will be the 38th regular-season outdoor game the NHL has held and the 37th that Dean Matsuzaki will have been a part of
The NHL executive vice president of events said it never gets old
“It is amazing the way people embrace these outdoor games,” Matsuzaki said Thursday
“and the excitement within the city that comes along with these games has been wonderful.”
That excitement is growing with the rink build underway for the game between the Edmonton Oilers and Calgary Flames on Oct
The only outdoor game Matsuzaki was not involved with was the first one
which happened to be the 2003 Heritage Classic
“I was definitely watching the first game here (on television) and I saw the spectacle that it was
and admit I still get goose bumps walking into the stadium on game day every time we do one of these games,” Matsuzaki said
“It is amazing and it will be amazing next week.”
Crews are hard at work installing a rink inside the 57,000-seat stadium
originally constructed for the 1978 Commonwealth Games
The venue has undergone numerous renovations over the years and is home to the Edmonton Elks of the Canadian Football League
“Every stadium we go to has its unique challenges,” Matsuzaki said
The game time is designed that if we’re getting weather like today (sunny
68 degrees) the puck drop is after the sun goes down past the edge of the stadium
it’s about field access and things like that
Playing in different venues is part of the appeal of an outdoor game
when the Oilers lost 4-3 to the Montreal Canadiens on Nov
Matsuzaki has overseen games at baseball stadiums such as Wrigley Field in Chicago
and Yankee Stadium and Citi Field in New York
The highest-attended NHL outdoor game was the 2014 NHL Winter Classic at Michigan Stadium in Ann Arbor
nicknamed “The Big House,” where the Toronto Maple Leafs won 3-2 in a shootout against the Detroit Red Wings in front of 105,491 fans on Jan
“I tell people they really have to come to one,” Matsuzaki said
an amazing event and we always have great entertainment.”
RELATED: More coverage of 2023 NHL Heritage Classic
The original Heritage Classic drew 57,167 fans to Commonwealth Stadium despite bitterly cold temperatures that dipped to minus 22 with the wind chill. It will not be as cold this time, with the forecast calling for a high temperature in the upper 30s.
Heather Seutter, director of Commonwealth Stadium for the city of Edmonton, attended the first Heritage Classic.
In addition to the game, there will be concerts around the city. Nickelback, the Canadian Music Hall of Fame rock group, will perform after the first intermission, and all-female Canadian band The Beaches will play a pregame concert at Clarke Stadium, located next to Commonwealth.
“We know that the weather is going to be so much better this year with the date of the game being in October,” Seutter said. “And we’re going to be able to celebrate the Battle of Alberta with the Oilers and the Flames here in the stadium.”
The 2023 Heritage Classic is one of four outdoor games scheduled for this season. The Seattle Kraken will host the Vegas Golden Knights in the 2024 Discover NHL Winter Classic on Jan. 1 at T-Mobile Park, and the 2024 Navy Federal Credit Union NHL Stadium Series at MetLife Stadium in East Rutherford, New Jersey, will feature the Philadelphia Flyers facing the New Jersey Devils on Feb. 17 and the New York Rangers taking on the New York Islanders on Feb. 18.
“Every year people come to us and tell us they want to do an outdoor game and we weigh a lot into it,” Matsuzaki said. “We try to accommodate everyone as best we can. The amount of technology that has gone into rink-building and how we’ve learned from each one of them, it’s allowed us to go a lot more places and schedule the games around certain things. It definitely has opened up a lot more possibilities around these games.”

“To do or not to do” is a fundamental decision that has to be made in daily life
Behaviors related to multiple “to do” choice tasks have long been explained by reinforcement learning
and “to do or not to do” tasks such as the go/no-go task have also been recently discussed within the framework of reinforcement learning
alternative actions and/or the non-action to take are determined by evaluating explicitly given (overt) reward and punishment
we assume that there are real life cases in which an action/non-action is repeated
even though there is no obvious reward or punishment
because implicitly given outcomes such as saving physical energy and regret (we refer to this as “covert reward”) can affect the decision-making
mice chose to pull a lever or not according to two tone cues assigned with different water reward probabilities (70% and 30% in condition 1
the probability that they would choose to pull the lever decreased (<0.25) in trials with a 30% reward probability cue (30% cue) in condition 1
and in trials with a 10% cue in condition 2
but increased (>0.8) in trials with a 70% cue in condition 1 and a 30% cue in condition 2
even though a non-pull was followed by neither an overt reward nor avoidance of overt punishment in any trial
This behavioral tendency was not well explained by a combination of commonly used Q-learning models
which take only the action choice with an overt reward outcome into account
we found that the non-action preference of the mice was best explained by Q-learning models
which regarded the non-action as the other choice
and updated non-action values with a covert reward
We propose that “doing nothing” can be actively chosen as an alternative to “doing something,” and that a covert reward could serve as a reinforcer of “doing nothing.”
the non-action is considered irrelevant to any overt reward or punishment
and is frequently neglected from the analysis
can learning of the non-action be explained by an increase in the value of the non-action according to such a covert reward
is the non-action chosen because of the reduction in the action value
To address these issues, we developed a new behavioral paradigm in which head-fixed mice choose to either pull a lever with their right forelimb or to not pull the lever after either of two tone cues with different reward probabilities is presented in each trial (Terada et al., 2018)
Although the head-fixed condition was more stressful for the mice than a free-moving condition
we head-fixed them so that two-photon and/or one-photon calcium imaging could be applied during this behavioral paradigm in future experiments to detect the relevant cortical activity
The behavior was well explained by the models that updated the non-pull value with a covert reward every time the non-pull was chosen
our models suggest that the subjective goodness of the overt reward depended on the inverse of the total expected outcome included in the task
We propose that the animals learn “not to do,” even if no reward is explicitly presented as the outcome of “not to do,” and no punishment is explicitly given as the outcome of “to do.”
All animal experiments were approved by the Institutional Animal Care and Use Committee of the University of Tokyo
Male C57BL/6 mice (aged 2–3 months at the starting point of the behavioral training; SLC
Japan) were used in the experiments in this study
The mice had not been used for other experiments before this study
All mice were provided with food and water ad libitum
and were housed in a 12:12 h light–dark cycle starting at 8 am
All behavioral sessions were conducted during the light period
Mice were anesthetized by intramuscular injection of ketamine (74 mg/kg) and xylazine (10 mg/kg) before an incision was made in the skin covering the neocortex
atropine (0.5 mg/kg) was injected to reduce bronchial secretion and improve breathing
an eye ointment (Tarivid; 0.3% w/v ofloxacin; Santen Pharmaceutical
and lidocaine jelly was applied to the scalp to reduce pain
Body temperature was maintained at 36–37°C with a heating pad
Japan) was attached to the skull using dental cement (Fuji lute BC; GC
Japan; and Bistite II or Estecem II; Tokuyama Dental
The surface of the intact skull was coated with dental adhesive resin cement (Super bond; Sun Medical
An isotonic saline solution with 5% w/v glucose and the anti-inflammatory analgesic carprofen (5 mg/kg
United States) was injected once intraperitoneally after the surgery
Mice were allowed to recover for 3–5 days before behavioral training
After recovery from the head-plate implantation
the mice were water-deprived in their home cages
They received about 1 mL water per session every day
and were sometimes given additional water to maintain their body weight at 80–85% of their initial weight throughout the experiments
The mice were usually trained for five consecutive days per week
and were given a 1.2–1.4 g agar block (Oriental Yeast Co.
The behavioral apparatus (sound attenuation chamber
and integrated lever device) was manufactured by O’hara & Co.
The lever position was monitored by a magnetic sensor and was continuously recorded at an acquisition rate of 1000 Hz by a NI-DAQ (USB-6001
The sound control and water delivery were controlled using a program written in LabVIEW (National Instruments)
the mice learned to pull the lever for a duration of more than 0.2 s within 1 s after the cue presentation (at 91.9 ± 7.2% of trials after presentation of tone A
The mice then started the lever-pull task with different reward probabilities
In the lever-pull task with different reward probabilities (Figure 1A)
either of the tone cues used in the pre-training sessions was randomly presented
but tone A was presented in 30% of trials and tone B was presented in 70% of trials
The mice were head-fixed in a way that allowed them to pull the lever within 1 s after the cue presentation
The difference from the pre-training sessions was that a different reward probability was assigned to each tone cue
if the mice pulled the lever for longer than 0.2 s
they received a 4 μL drop of reward water at probabilities of 70% and 30% in tone A and B trials
the corresponding probabilities were 30% and 10% for tone A and B trials
The next trial started 3–4 s after the last time point at which the lever was returned to the home position (after the lever went below the 1.6 mm threshold)
or after the presentation of the previous tone cue when the lever did not exceed the threshold
The presentation probability for tone A was fixed at 30% so that the expected reward per unit of time (if the mice pulled the lever in all trials) was similar between both cues (expected rewards in tone A and B
0.7 × 0.3 and 0.3 × 0.7 in condition 1
and 0.3 × 0.3 and 0.1 × 0.7 in condition 2)
The data were analyzed using MATLAB (MathWorks
The behaviors of 13 mice were used for condition 1
the lever-pull choice probability had decreased below 0.25 in tone B trials by training session 20
The latter session of two consecutive sessions in which the mice pulled the lever for more than 80% of tone A trials and less than 25% of tone B trials was set as the last session
No apparent abnormal choice behavior was observed on the day after a break (e.g.
the behavior of the mice was analyzed from the start session to the last session
To omit periods when the motivation of the mice could be considered to be too high or too low within each session
the behavioral data used was taken from the first trial after the mice obtained 30% of the total amount of the reward they got through the session to the last trial before they obtained 70% of the total amount of the reward
The lever-pull rates (the number of successful lever-pull trials divided by the number of presented cues) averaged over the tone A and tone B trials in the early part of each session covering the first 30% of rewarded trials
the middle part of each session covering the 30th–70th percentiles of the rewarded trials
and the late part of each session covering the 70th–100th percentiles of the rewarded trials
and 0.367 ± 0.115 in condition 2 (n = 8 mice)
All behavioral data were summarized as binary data with action (to pull or not), cue type, and reward. The trial sequence in each session was determined by the same criterion as the behavioral analyses. The sequences from a single animal were concatenated through all sessions (Figure 2A, top). The series of data were then separated into two sequences consisting of the same tone cue trials (Figure 2A
and were used to model the learning process of the mice

Orange and cyan traces represent the 10-trial moving-average of the actual pull-choice [the same as in (A)]
Red and blue traces represent the predicted pull-choice probability
we built a “simple model” that assumed a value for pulling of the lever QX
pull(t) and a value for non-pulling of the lever QX
non–pull(t) in the t-th trial for each tone cue (X ∈ {A
pull(t) was updated when the mice pulled the lever as follows:
κr is the subjective goodness of a water reward
and rX(t) is 1 when the water reward was delivered
or is otherwise 0 in the t-th trial for tone X
non–pull(t) was updated when the mice did not pull the lever as follows:
because rX(t) was always 0 in non-pull trials. In the “F (forgetting) model” (Barraclough et al., 2004; Ito and Doya, 2009)
non–pull(t) were updated in the same manner as in the simple model
pull(t) in trials without the lever-pull was also updated as follows:
In any models without “F” described below
non–pull(t) in trials with the lever-pull was updated as follows:
The pull-choice probability for the (t + 1)-th trial for tone X
was calculated using the following softmax function:
non–pull(1) to be 0 because the mice pulled the lever with the reward probability of 100% in pre-training sessions before the first model-fitted session started
non–pull(t) was zero in equation (4)
non–pull(t) = 0 through the whole sessions in all models
except for the following “saving” and its derivative models
equation (7) in the “simple” and “F models” equals to
In the “cost model” and “cost-F model” (Skvortsova et al., 2014)
where κc (≥0) represents the subjective cost accompanying pulling of the lever
pull(t) can also be reduced by the aversiveness when the lever-pull is not rewarded
pull(t) can be written as κrrX(t)−κe(1−rX(t))
where κe (≥0) represents the subjective emotion evoked by an unrewarded lever-pull and is deformed as follows:
As equations (9) and (10) are mathematically equivalent
we considered only equation (9) as the cost model
pull(t + 1) was determined by equation (8)
In the “irregular REL (irREL) model” and “irREL-F model,” we modified the RELATIVE model, which refers to the value of the “context” when updating the Q-value (Palminteri et al., 2015; Klein et al., 2017)
we assumed that the “context” was the set of the task
the counterfactual situation was tone B trials
When the mice pulled the lever in the t-th trial for tone X and the t-th trial for tone X corresponded to the tAB-th trial among the total trials including both tone A and B trials
pull(t + 1) was calculated referring to the contextual value V(tAB) calculated with the estimated counterfactual option value QY
where αv is the update rate of contextual value V
V was updated every trial regardless of the tone type
QY,pull(tY) is the value for the pull for tone Y in the tone Y trial immediately before the t-th trial for tone X
When the lever was not pulled in the t-th trial for tone X
pull(t) was updated according to equation (5)
pull(t + 1) was calculated according to equation (8)
In the “saving” and “saving-F” models
pull(t) was updated according to equations (1)
non–pull(t) was updated when the mice did not pull the lever as in equation (3) and
where ψ (≥0) is the goodness of the covert reward, which is assumed to be constantly obtained as a result of a non-pull (the saving of the cost accompanying the lever-pull) (Lee et al., 2016; Cheval et al., 2018)
non–pull(t) decayed when the mice pulled the lever according to equation (6)
the point of inflection of the sigmoidal function is offset to the right to let PX
where βo (0 < βo < 1) is an offset term of the sigmoidal function (or non-pull bias) and is constant throughout the session
In the “I (inertia)” model, we took the history of pull and non-pull choices in the t-th trial into account (Akaishi et al., 2014; Katahira, 2018)
When the lever was pulled in the tAB-th trial among the total trials including both tone A and B trials
choice trace C(tAB) was updated as follows:
where τ is a decay constant of the choice history (0 ≤ τ ≤ 1) and φ (>0) is the subjective weight for repeating the same choice
When the lever was not pulled in the tAB-th trial
C ranged from −φ to φ
The parameters used for each model are summarized in Table 1
Summary of the free parameters used in each Q-learning model
Maximum log likelihood estimation was used to fit the parameters used in all models
The likelihood (L) was determined using the following formula:
where z(t) is the likelihood for the t-th trial
We took the logarithm of this likelihood and multiplied it by −1 so that we could use the fmincon function with appropriate lower and upper bounds for each free parameter in MATLAB
To compare the models, Akaike’s information criterion (AIC) and Bayesian information criterion (BIC) were calculated using the following formulas (Daw, 2011):
where K is the number of free parameters to fit
and Tn is the number of trials used for fitting
For visual presentation of time series of the estimated Q-values in tone A and B trials in the saving-F model (Figure 9)
the values for each animal were normalized by the spline interpolation
The estimated values were up-sampled to the series of 5000 data points by spline function
and then averaged across animals in each condition
To analyze the generative performance of the saving-F and saving-F-I models, we used these models to simulate the lever-pull choice behavior of the mice (Ahn et al., 2008; Palminteri et al., 2015, 2017)
the same sequences of tones across sessions were used as in the actual settings
and the fitted values of the free parameters were used as substitutes for the equations above
the lever-pull choice (pull or non-pull) was calculated randomly according to the pull-choice probability estimated by equation (7) in the saving-F model
When the lever was pulled in the simulated t-th trial in which it was actually pulled
When the lever was pulled in the simulated t-th trial in which it was not actually pulled
rX(t) was defined according to the determined probability (condition 1
and C(1) were the same as those for the fitting
The lever-pull rate was calculated in the same way as the analysis of the actual behavior and averaged over the 1000 simulations
The goodness of the generative performance was estimated as the proportion of trials in which the simulated pull/non-pull-choice was the same as the actual pull/non-pull-choice
Data are presented as mean ± standard deviation unless otherwise indicated
Error bars in the line plots represent the standard error of the mean
The Wilcoxon signed rank test and the Wilcoxon rank-sum test were used for statistical testing in the behavioral analyses
All statistical tests performed were two-tailed
These results suggest that as the session progressed
the mice came to expect the reward more strongly
and learned to pull the lever for longer in tone A trials than in tone B trials
These results indicate that the decision on whether to pull or not does not depend solely on the absolute outcome assigned to each tone
The number of rewarded lever-pulls per minute was similar between the first session and the last session (condition 1
Although the saving of working time (lever-pull time) could mean more overt (water) reward availability
the similar number of rewards per minute between the first and last sessions suggests that the reason why the mice decreased the pull rate in tone B trials was not because the time saved by skipping the lever-pull in tone B trials increased the overt reward
We postulated that the mice might learn a strategy to not pull in tone B trials to save on the pull-associated cost
We then attempted to model these mouse behaviors in the framework of reinforcement learning. In a standard reinforcement learning scheme such as Q-learning, the outcome after action choices is evaluated according to an explicitly given reward (Sutton and Barto, 1998)
we assumed that the mice chose either of the pull or non-pull choices
When the action value defined as Qaction and the non-action value defined as Qnon–action are assigned to a sigmoidal function
although the predicted pull-choice probability in tone B trials was still not below 0.5
which suggested the relative value compared with the expected reward obtained in the context as the critical decision-making factor
and it well explained the choice action behavior when the different cues were simultaneously presented
Although tones A and B were not simultaneously presented in the current task
we assumed that the mice determined whether to pull according to the difference in the values between the presented and unpresented (factual and counterfactual) tone trials
the contextual value (task-environment value) V should be larger than the actual reward in tone B trials
pull < 0.5 (see “Materials and Methods”)
As the different cues are not simultaneously presented
we call this model the “irregular RELATIVE (irREL) model.”
In the third “saving model,” we assumed that the animals might find a positive value (“covert reward”) in the non-action (non-pull) because a non-pull would save the physical cost involved in performing the lever-pull (or allow a rest), and avoid the negative emotion after a lever-pull was not rewarded (Lee et al., 2016; Cheval et al., 2018; Sweis et al., 2018)
if the pull value is smaller than the non-pull value
the predicted pull-choice probability would be <0.5
a constant reflecting the subjective goodness of the cost-saving (as covert reward) ψ accompanying the non-pull was introduced into the simple model
although the mice did not explicitly obtain anything when they did not pull the lever (see “Materials and Methods”)
In all three models, the long-term trends in the pull-choice probability fitted well for both tone trials, including the pull-choice probability under 0.5 in tone B trials (Figures 3A–C)
Figure 3. Three Q-learning models to explain the pull-choice probability. Six representative predicted pull-choice probabilities of the models in tone A (left) and B (right) trials in conditions 1 (top three rows) and 2 (bottom three rows). Orange and cyan traces represent the 10-trial moving-average of the actual pull-choice (the same as in Figure 2)
Red and blue traces represent the predicted pull-choice probability in cost (A)
This indicates that αf was an important parameter to explain mouse behavior in the models
especially those in which it did not directly inhibit the prediction of a lever-pull choice probability of <0.5
Figure 4. The saving-F model well-explains the pull-choice probability and trial-by-trial fluctuation. (A–C) Six representative predicted pull-choice probabilities of the models in tone A (left) and B (right) trials in conditions 1 (top three rows) and 2 (bottom three rows). Orange and cyan traces represent the 10-trial moving-average of the actual pull-choice (the same as in Figure 2)
Red and blue traces represent the predicted pull-choice probability in cost-F (A)
or saving) with and without introduction of αf as a free parameter (w/F-term–w/o/F-term)
A negative value indicates that the model prediction with αf was better than that without it

Orange and cyan traces represent the 10-trial moving-average of the actual pull-choice (the same as in Figure 2)
Red and blue traces represent the predicted pull-choice probability in cost-F-O (A)
These results suggest that the update of the non-pull value with covert reward
was essential to explain the mouse choice-behaviors in this task

and saving-F-I models in conditions 1 (A) and 2 (B)

and saving-F-I models in conditions 1 (C) and 2 (D)
Red dots indicate the model with the minimum score for each mouse
Each number indicates the number of the red dots in the corresponding model
which suggests that the saving-F model was better as the generative model than the saving-F-I model

(A) Six representative simulated pull-choice probabilities with the saving-F (dark green) and saving-F-I (light green) models in tone A (leftmost and second right) and B (second left and rightmost) trials in conditions 1 (leftmost and second left) and 2 (second right and rightmost)
Traces represent the 30-trial moving-average of the actual (black) or simulated pull-choice
(B) Mouse-averaged actual (black) and simulated (saving-F model
light green) lever-pull rates in tone A (left) and B (right) trials in conditions 1 (top; n = 13 mice) and 2 (bottom; n = 8 mice)
(C) The proportion of trials in which the simulated pull/non-pull-choice was the same as the actual pull/non-pull-choice (“concordance rate”) in conditions 1 (top) and 2 (bottom)
the concordance rate was calculated for each simulation and averaged over the 1000 simulations
and κr were similar between the saving-F and saving-F-I models
but the values of αf were larger in the saving-F model than in the saving-F-I model
The introduction of choice history might play a role in fitting with the persistency effect from a few preceding choices
without changing the values for the pull and non-pull
this persistency effect might be substituted by the decay of the value of the non-persistent choice with the larger αf
the ratio of the median κr in condition 2 to that in condition 1 (2.32 = 13.77/5.93 and 2.75 = 11.89/4.33 in the saving-F and saving-F-I models
respectively) was comparable to the inverse of the expected overt reward per trial in condition 2 divided by that in condition 1 (2.59 = [0.16/0.42]–1)
These results suggest that the mice recognized the infrequent water delivery as being more valuable than the frequent delivery
while the learning rate and the weight of the choice history did not depend on the combination of the reward probabilities assigned to the tones

The total trial number was normalized across animals
(E) Pull values in tone X trials in the last session
X is B in condition 1 and A in condition 2
(F) Non-pull values in tone X trials in the last session
These results suggest that the non-action could be more valuable than the action in trials with a reward probability of 30% in condition 1
but less valuable in those trials in condition 2
pull) in condition 1 and the unchosen non-lever-pull (QA
non–pull) in condition 2 became close to zero in the last session
the same reward probability-assigned trials induced different choice behavior
which could be determined by the inverse of the expected overt reward through the task
we developed a new behavioral paradigm to let mice choose to pull or not pull a lever according to tone cues with different reward probabilities
We found that they came to not pull in relatively lower-reward-expected trials
although the predicted behavior according to an explicitly given reward-maximization policy would be to pull the lever in all the trials unless skipping tone B trials would result in an increase in the total rewards per unit time
in which the pull value was updated by the overt reward
the non-pull value was updated by the covert reward
the pull value was reduced according to the pull cost
the relative pull value was based on the tone context
and the pull offset (or non-pull bias) and/or the inertia of the choice history was included
We found that the best models were saving-F or saving-F-I models that updated the pull value with the overt water reward
updated the non-pull value with the covert reward
and the value of the unchosen choice decayed
the current study is the first attempt to indicate that a covert reward might be engaged in non-action learning using a reinforcement learning framework
when the animal repeatedly chose the non-pull
Even when the action offset and/or the choice inertia were added to the simple
the predictions were worse than that of the saving-F-I model
The prediction by the saving-F model was better than those by the I model and F-I model
we conclude that the active learning of non-action with the covert reward contributed to decision-making
The advantage of the saving-F models may be that the animal can increase its preference to either the pull or non-pull direction in each trial
allowing the choice preference to converge to the final one faster than it can with the models without the non-pull value updated by covert reward
The effectiveness of the choice history on the prediction in the saving-F-I model might reflect the fact that the mice tended to be persistent in pull or non-pull choices for a few trials
the saving-F model was better than the saving-F-I model as the generative model to describe the behavioral effect
In the simulation with the saving-F-I model
the averaged lever-pull rate in tone A trials was around 0.5 in condition 1 and <0.5 in condition 2
and the mice chose not to pull in tone B trials as the sessions progressed
This might result in that the inertia of non-pull-choice in tone B trials inhibited maintenance of the high lever-pull rate in tone A trials in the simulation
and/or the saving-F-I model was overfitted
The role of inertia needs further validation in future studies
Our results suggest that our animals could actively choose the non-action by evaluating the non-action in the form of the covert reward
Our study sheds light on the favorable aspect of non-action through preventing an aversive cost (or energy) inevitably related with the action
and proposes that non-action could be reinforced by itself
it might be useful to examine the correlation between the value of ψ and quantifications of the lever weight
which was similar between conditions 1 and 2
κr was ∼2.5-fold larger in condition 2 than in condition 1
which is in inverse proportion to the net reward expectancy when the mice pulled in all trials regardless of tone types
This suggests that the mice recognized the infrequent water delivery as being more valuable than the frequent delivery
This may be regarded as being analogous to a puddle found in the desert
It is necessary to examine the relationship between κr and the net overt reward using other combinations of reward probabilities

Metrics details
The gut microbiota exist within a dynamic ecosystem shaped by various factors that includes exposure to xenobiotics such as pesticides
It is widely regarded that the gut microbiota plays an essential role in maintaining host health
including a major influence on the brain and behaviour
Given the widespread use of pesticides in modern agriculture practices
it is important to assess the long-term collateral effects these xenobiotic exposures have on gut microbiota composition and function
exposure studies using animal models have shown that pesticides can induce negative impacts on the host gut microbiota
there is a growing body of literature showing that the effects of pesticide exposure can be extended to the manifestation of behavioural impairments in the host
With the increasing appreciation of the microbiota-gut-brain axis
in this review we assess whether pesticide-induced changes in gut microbiota composition profiles and functions could be driving these behavioural alterations
exposure dose and variation in experimental designs hinders direct comparisons of studies presented
the mechanistic connection between the gut microbiota and behavioural changes remains insufficiently explored
Future experiments should therefore focus on causal mechanisms to examine the gut microbiota as the mediator of the behavioural impairments observed in the host following pesticide exposure
if changes in gut microbiota composition and function from microbe-pesticide interactions are the driving factor for the negative behavioural changes
we evaluate the emerging evidence that there is a causal relationship between pesticide exposure and behavioural alterations via the microbiota-gut-brain axis
We propose the gut-brain axis as a potential avenue for further understanding the overall effects of pesticides on gut and brain health
there is a large body of evidence to suggest a role of pesticides present in food
air) in shaping the gut microbiota with a potential link to behaviour
much of this understanding has been driven by studies in environmental systems like water and soil
with information on gut microbiota communities comparatively lacking
The aim of this review is to first summarise currently known impacts of common pesticides on behaviour and gut microbiota in various animal models
we will discuss the current research and future avenues for identifying causes and mechanisms underpinning negative implications of pesticide exposure from the microbiota-gut-brain axis perspective
While this discrepancy could be due to differences in behavioural tests applied
it highlights the need for replication of the study with a lower dose
which suggests that biologically available neuromodulators are altered due to microbiome alterations from pesticide exposure
All of these findings point to the chemical impact on the microbiota-gut-brain axis having multiple underlying mechanisms
it further strengthens that glufosinate ammonium induced shifts in microbiota community structure
which can alter the biochemical environment (e.g.
Although the authors did not draw any direct conclusions on the mechanism
the Pearson correlation analysis of gut microbiota and metabolic profile highlighted that the perturbations in the gut microbiome may impact lipid and glucose metabolism through numerous pathways including an interference with bile acid secretion
these findings suggest gut microbiota metabolites altered by pesticide exposure may induce general behavioural impairments on the host via the microbiota-gut-brain axis
while some impacts may be by pesticide-specific processes
causational studies are strongly warranted to understand the specific involvement of gut microbiota in the process
This divergence may be explained by the difference in animal models
exposure duration or exposure time window (directly in adulthood vs indirectly via the mother during early life)
it requires additional studies to draw firmer conclusions
behavioural analysis is currently lacking for hosts exposed to chlorpyrifos
thus requiring further experimental evidence
These observations together strengthen the argument that pesticide exposure and altered microbially derived SCFA levels leading to behavioural changes
potentially by disturbing integrity and the function of the physical barriers of the brain and the gut
these studies suggest that gut bacteria compositional changes exert immunomodulatory effects that could plausibly impact host behaviour
there is yet to be a study which included both immune functions and behavioural readouts
It is strongly suggested that including behaviour with gut microbiota studies are required to understand the significance of disrupted microbiota-gut-brain axis signalling upon pesticide exposure
there were some species-dependent trends in gut microbiota profile alterations
results from an environmentally relevant dosage are yet to be fully understood
reduction in this beneficial bacterial group from pesticide exposure may be one potential factor of its detrimental impact on host behaviour
A major environmental concern is that this type of impact may be translated to humans
These results highlight once again that pesticide exposure can differentially impact specific genera of the gut microbiota in a host-species specific manner
the potential that these taxa-specific changes are achieved through the direct action of the pesticide on the microbes or through modulation of host metabolism remains unclear
future studies should incorporate 1) studies targeting the mechanistic and biological interactions between the pesticides and bacterial groups and 2) the functional implications of the microbiome ecosystem-wide changes
More studies incorporating pesticide-altered gut microbiota transplantation will allow us to investigate the impacts of gut ecosystem changes in driving behavioural impairments
All this information is crucial to be included in the manuscript for future studies to be replicated accordingly
we will be able to understand the full picture of the complex interaction between the pesticide and host

and overall health from the world's #1 in orthopedics
Excited to get back on the slopes this season? A little pre-ski-trip prep can go a long way in preventing injuries, says Yukiko Matsuzaki, PT, DPT, OCS, SCS
a clinical specialist in orthopedic and sports physical therapy in Pediatric Rehabilitation at HSS
it’s been two years since many people last went skiing,” says Matsuzaki
your body may have gone through minor or even significant changes
Kids could be 5 inches taller than they were in 2019
whereas an older adult may have lost an inch of height
Our feet can change size and shape as we age
cardiovascular fitness and body weight have changed for many people
All these factors can impact how well your first ski trip of the season goes
Even if none of that is true for you, diving into any seasonal sport with too much zeal can raise your risk of a sprain, strain or other injury. While it’s always better to spend a few weeks getting mentally and physically ready (see How to Prepare for Injury-Free Skiing)
these last-minute tips from Matsuzaki can make a difference
Two years is a long time for anything to languish
Your bindings could have dry rotted or your gear may no longer fit
Or maybe you’ve been borrowing gear and it never fit in the first place
Matsuzaki recommends making an appointment at a ski store to have a pro evaluate what you have on hand
they’re going to need new everything,” she notes
“You should be able to stand on one leg with your eyes open for 30 to 60 seconds without falling over,” she says
try it with your eyes closed.” You can make it even more challenging by standing on an uneven surface or doing something like tossing a ball against a wall
which may require you to not only balance on but also make quick adjustments on one leg at a time
If you wake up and the weather seems iffy—or if your gut’s telling you it’s not a good day to ski—find something else to do for the day
weather and mountain conditions can change from one hour to the next
Most resorts will post a report on conditions
as well as info on trail closures and difficulty
Remember that your brain took a break from skiing
“so your reaction time may not be what it once was.”
Bonus tip: Check the resort website’s COVID-19 requirements regarding masking
vaccination status and social distancing before you go
so you won’t get turned away at the desk or a restaurant later on
You may be a bit more sore and achy during your first ski weekend of the year
so listen to your body and take a break when you need one
so you should take a break after an hour or so even if you feel great,” she adds
have a snack and reapply sunscreen—all of which will make for a better experience
even if it’s only been an hour or two: Injuries are more common during the “last run” when people push themselves past their limits
be flexible with your plans and be prepared to go to a plan B or C
like cross-country skiing or curling up with a good book in the lodge
you want to try to prevent injuries,” says Matsuzaki
“You can’t control everything on the slopes
but these are some of the things that you can control.”

The acetabulum is a cup-shaped part of the pelvis. The ball-shaped femoral head (the tip of the femur or thighbone) fits into the acetabulum to form the hip joint.
Analgesia is the reduction of pain by a method in which a patient remains conscious (as opposed to being put unconscious, such as during general anesthesia).
Arthritis is a disease in which inflammation in a joint causes pain and stiffness that can limit a person's movement.
Arthroplasty is an orthopedic surgery to fix or rebuild a joint (where two or more bones meet, such as in the shoulder or knee). Arthroplasty usually involves removing the surface of a bone at the point where it joins another, and replacing that surface with an artificial implant. A hemiarthroplasty is when only one of the bones in a joint is resurfaced or replaced. In a total joint arthroplasty (also called total joint replacement), the bones of the entire joint are rebuilt.
An arthroscope is a flexible, fiberoptic tool fixed with a small camera and used to visually examine the inside of a joint. Specially designed arthroscopic surgical tools are also used to perform minimally invasive joint surgery.
Articular means of or related to the joint. For example, articular cartilage refers to cartilage of a joint.
An autoantibody is an antibody produced by a person's immune system to attack the body's own natural tissues or proteins. It is caused by an abnormal response by the immune system, which misidentifies the body's natural tissue as a harmful external invader (such as a harmful bacteria or virus).
A black box warning (sometimes also called a "boxed warning") is, in the United States, the strictest prescription drug warning label required by the US Food and Drug Administration (FDA). The FDA requires pharmaceutical makers to apply these warnings on any prescription drug in which medical studies have demonstrated a significant associated health risk.
A blood clot is a thickening of the blood. It is a normal function of the body to stop bleeding at the surface. But when a blood clot incorrectly forms inside an artery or vein, it can decrease the flow of blood and create dangerous health problems.
Also called an "osteophyte," a bone supr is a protruding, bony overgrowth that forms at the edge of a bone. It often forms at a joint where two bones meet. It is usually caused by osteoarthritis.
A bursa is a fluid-filled sac that provides cushioninng between bones and tendons and other soft tissues. In a synovial joint such as the knee or shoulder, a synovial bursa reduces friction between the bones and soft tissues of the joint, allowing them to glide together smoothly.
Bursitis is the inflammation of a bursa, a fluid-filled sac that provides cushioninng between bones and tendons and other soft tissues. In a synovial joint such as the knee or shoulder, a synovial bursa reduces friction between the bones and soft tissues of the joint, allowing them to glide together smoothly.
A case report details the symptoms, diagnosis, treatment and medical follow-up of a single patient rather than a broad study of multiple patients.
Sometimes also called "clinical series," a case series is a type of medical research study that either tracks patients with a known exposure (such as patients who have received a similar treatment), or examines their medical records for exposure and outcome.
Congenital means existing since birth rather than developing or becoming acquired during one\'s lifetime.
Connective tissue is a soft, bodily tissue that supports, connects and/or separates various parts of the body. This includes skin, cartilage and other tissues found in and around the joints and major organs, such as the heart, lungs and kidneys.
Contraindication refers to something a person has (such as a symptom, condition, disease or medication regimen) that makes it inadvisable for them to receive a particular medical treatment or procedure, because of possible complications or ill effects.
Fascia is a fibrous band or sheet of connective tissue that encloses and separates muscles or organs in the body.
The femoral head is a ball-shaped portion of bone located at the top of the femur (thighbone). This is also referred to as the head of the femur. It is supported by the femoral neck.
A femoral osteotomy is an osteotomy (surgical cutting or removing of bone) of the femur (thighbone) performed to correct deformities or other conditions of the femur or the hip joint.
Flexion is the bending of a limb at the joint, such as with the elbow or finger. (This is the opposite of extension, which is the straightening of a limb at the joint.) Flexion can also refer to the forward raising of the arm (at the shoulder joint) or leg (at the hip joint).
Long bones are category of bones that are longer than they are wide. It includes the clavicle (collar bone) as well as several bones that compose the limbs (arms and legs), fingers, and toes. By contrast, "short bones," such as the patella (kneecap), are about as wide as they are long.
A lumbar puncture (also called a spinal tap) is a procedure in which a syringe needle is inserted between two vertebrae (spine bones) in the lumbar section of the spine (lower back). The needle is then used to collect a sample of cerebrospinal fluid for laboratory testing.
A meniscus (plural, "menisci") is a pad of fibrocartilage inside a joint. It provides cushioning and protect to the joint. The knee joint, for example, contains two menisci: A medial meniscus (located on the inner side of the knee) and a lateral meniscus (located on the outer side).
Microsurgery is an intricate surgery that is performed under a microscope using miniature instruments.
A mouse model is the use of specially bred mice to study a human disease or condition, as well as how to prevent or treat it. Mice are the most common animal model used to study human disease because they are biologically similar to humans, sharing virtually the same set of genes (on average, the protein-coding regions of the mouse and human genomes are 85% identical). Because of these gene similarities, mice and humans contract many of the same diseases.
A myelogram is an imaging procedure in which a needle is inserted into the spinal canal to inject iodine that contains a contrast agent (or "contrast medium"into the sac that contains the spinal cord and nerve roots. The contrast agent increases the color contrast of the body structures and fluids in order to enhance the images. This helps the radiologist identify problems and make a diagnosis.
Neurological deficit is an abnormal or decreased bodily function caused by damage to nerves, the spinal cord or the brain. Such deficits can include symptoms such as loss of speech, poor reflexes, muscle weakness, neuropathies, balance problems or cognitive impairment, among others.
A neuroma is a tumor or mass of nerve fibers or other tissue that grows out from a nerve.
Neuropathic pain is pain caused by damage to or disease of the nervous system, rather than by the stimulation of pain receptors from an outside force (such as fire, blunt trauma, etc.).
An ossicle is a term used usually to describe a small calcification adjacent to a bone, or sometimes a more substantial, “accessory bone” (extra bone).
An osteoid is the precursor to bone tissue, which is made of nonmineralized protein, including collagen. As calcium and other minerals deposit into the osteoid, immature or "woven" bone is formed.
An osteophyte, more commonly called a "bone spur," is a protruding, bony overgrowth that forms at the edge of a bone. It often forms at a joint where two bones meet. It is usually caused by osteoarthritis.
An osteotomy is the surgical cutting or removing of a piece of bone.
Parry-Romberg syndrome is a progressive shrinkage and degeneration of tissues under the skin of the face, usually only on one side (known as "facial hemiatrophy" or "hemifacial atrophy"). Muscle, fat, facia tissue and even bone in the skull may degenerate.
Periarticular means located around an articular joint in the body.
Perioperative medicine is the medical care for surgery patients before and after their surgical procedure, not including the medical care provided during the procedure itself. This care continues through to the end of recovery.
Proprioception is sensory function that allows a person to determine the position of their body or a part of their body in space. Sensory receptors called proprioceptors receive stimuli and send signals to the brain to help a person maintaining balance. It is related to but slightly different from kinesthesia.
Recrudescence is the renewed outbreak of a disease after a period of inactivity.
Reduction is the physical realignment of a body part (such as a dislocated or broken bone) to its correct position. Reduction can be done surgically (open reduction) or nonsurgically (closed reduction), for example when setting a broken bone by hand.
Remission is a period during which a person with a chronic illness experiences few or no signs or symptoms of that condition. As opposed being "cured," having or being in a "remission" means that the condition symptoms could return. The physical circumstances that are considered to be a "remission" vary from disease to disease.
A reoperation is a repeated surgery or additional surgery for the same condition. A reoperation may be done to correct a problem not fixed during the original surgery, or for new problems that occur as a result of the first surgery.
The reward center is the brain's mesolimbic pathway, a set of neurons that synthesize and release dopamine, a chemical that regulates desire and motivation in response to a stimulus.
Sarcopenia is a syndrome encompassing loss of muscle mass, strength and performance. It can be measured by a bone density exam (DEXA). Once diagnosed, evaluation begins with a nutrition assessment. Patients may benefit from a physical therapy or rehab program.
A self-protein is a protein that is normally produced by a person's body. A person's immune system should be tolerant of self-proteins. If the immune system misidentifies a self-protein as an external, harmful invader (such as an infectious bacteria), it produces autoantibodies to attack it. This is called autoimmunity.
A syndrome is a group of symptoms that appear to be related to one another and characterize a health condition.
''Systemic'' refers to something that affects the whole body, rather than a part. An autoimmune disorder (or autoimmune disease) is where the immune system, which normally protects the body from outside invaders such as harmful bacteria, mistakenly attacks body tissues as though they were harmful invaders.
Tendinosis (also sometimes spelled "tendonosis") is the degeneration of a tendon.
Hollywood has created offensive stereotypes by yellowfacing Japanese actors for decades
I would like to be emailed about offers, events and updates from The Independent. Read our Privacy notice
I’ve survived as an Asian actor in Hollywood for 22 years, and for the past few, I’ve also helped them cast Japanese actors
And I watched up close how blatantly racist this casting process can be
Hollywood firmly believes that “Japanese” is an ethnicity
and they insist that Japanese actors must look quintessentially “oriental”
The first thing producers want is that actors can “pass” as Japanese
Mixed-race Japanese are just as Japanese as I could ever be
they are absolutely not considered “Japanese”
And because Hollywood wants to contrast “diverse America” with “homogeneous Japan”
but even I don’t look “oriental” enough for them
I cannot tell you how many times I was asked at auditions: “Are you Japanese
But you’re so tall.” Or: “Are both your parents Japanese?”
and they replied: “But all Japanese are straight-haired.” I explained to them that this isn’t the case
they straightened my hair because they felt that I didn’t look “authentic” enough
Hollywood needs to understand that it has created extremely offensive stereotypes by yellowfacing Japanese actors for many decades
You cannot imagine how agonising it is for me when I’m asked by young mixed Japanese actors for advice on how to make it in Hollywood
Because Hollywood has been shouting about the importance of “diversity”
they have been tricked into believing Hollywood is actually inclusive
Should I tell them the truth that Hollywood considers them “second-class Japanese”
Or they would never ever be cast because “they’re born to the wrong parents”
Hollywood would rather cast Asian American actors than mixed Japanese because they believe some of them look “more Japanese” than mixed Japanese
And the sad part is that because the Asian American community often isn’t aware of how mixed Japanese are treated
even when Asian Americans are cast for the wrong reasons
they praise Hollywood for advancing Asian American representation
Japan has literally zero minority representation
Though there have been hundreds of Japanese films where a gay man is a protagonist
not a single one of them has an openly gay man cast in that role
Many mixed Japanese have experienced being treated as foreigners
even though they were born and raised in Japan
This is what happens when there’s absolutely no representation – it impacts how people view their society and what they believe it should look like
The vast majority of mixed Japanese actors are registered with “international talent agencies” in Japan
Japan has been putting out a completely fictitious version of “homogenous Japan”
and Hollywood has been telling the world what Japanese people should look like
we are tricked into believing that there are no mixed-race Japanese
It’s been more than half a century since the Akira Kurosawa or Yasujirō Ozu era
Every time we “pay tribute” to Kurosawa/Ozu/Samurai/Kaiju/Yakuza films and call them “authentic”
we are subscribing to a false ideal of “homogenous Japan” which doesn’t exist in reality
This reinforces stereotyping and negates the existence of mixed Japanese
I cannot stay silent anymore about one of the most blatantly racist practices I’ve ever seen
And this is coming from a guy who’s been in the US for two decades as a foreigner
In order to fix this problem on both sides of the Pacific
It’s time to help Japanese filmmakers understand that diversity makes films better
and abolish the racist stereotypes that Hollywood have been regurgitating for more than half a century
I’m getting the ball rolling with Mosaic Street, a Japanese/English crime drama set in a near-future Japan where diversity is already a norm, starring openly transgender actress Kota Ishijima, openly lesbian actress Ami Ide, and Afro-Japanese actress Ema Grace.
This is what Japan is supposed to look like – diverse and modern.
If you work in Hollywood, please consider casting a mixed Japanese actor for your next film. You don’t need a “reason” to cast them. Just cast them for any of your characters. If you feel that you need to justify the casting, then you’re doing it wrong. Together, let’s right this wrong once and for all. It’s long overdue.

rooftop views and chef Yo Matsuzaki’s Japanese-inspired menu make Wren a soaring new destination in Tysons
I have yet to taste a morsel of food, but the bar at Wren has already made a favorable first impression
thanks to the savvy cocktail program by beverage director Luis Mantilla
Luxardo maraschino liqueur and allspice bitters
having aged for 30 days in a charred American oak barrel
My companion’s refreshing gin and (cucumber) tonic
it’s served in an enormous Burgundy wineglass and garnished with juniper berries
a lemon wheel and a thin strip of cucumber threaded onto a metal cocktail skewer like ribbon candy
We’re a few sips in when two of chef Yo Matsuzaki’s small plates arrive and prove just as captivating
The hamachi tartare—yellowtail sashimi mixed with olive tapenade
shallots and white-truffle vinaigrette—is served with a side of house-made potato chips that round out each bite with a nice crunch
Matsuzaki cures steelhead trout with fennel and beets
which lend hints of sweetness and licorice while turning the fish a stunning ruby red
He then arranges delicate slices of it around a pool of citrus sauce
with dots of orange trout roe and sprigs of shiso
If you haven’t been to Tysons lately, you’re in for a surprise. The area is undergoing a veritable renaissance. Wren, which opened in September on the 11th floor of the new Watermark Hotel, shares a rooftop with The Perch
a 2.5-acre outdoor “sky park” with manicured landscaping
a Starr Hill Biergarten and an outdoor amphitheater that hosts live concerts and airs major sporting events on a jumbotron
The restaurant and sky park are part of Capital One Center, a mixed-use development that comprises 6 million square feet of retail, hospitality and entertainment space. They sit atop Capital One Hall
a sparkling new performing arts center that’s home to a 1,600-seat proscenium stage
large-scale event spaces and a Wegmans grocery store
is so completely integrated into the Watermark’s loungy 11th-floor hotel lobby (with a pool table to boot) that on my first visit
I wasn’t even sure I was in the restaurant
I inquired at the handsome brass-and-glass bar—it’s shaped like the bow of a ship—if I was in the right place
“Sit wherever you want!” (They’ve since added a host stand
Eating at the bar is delightful but do try to score one of the tables positioned next to the stunning floor-to-ceiling windows
which offer a sweeping view of the Tysons skyline
Wren’s name—both a bird and a homophone for the Japanese word for love—reflects its dual identity as a high-styled izakaya (a casual spot for drinking and snacking) that speaks Japanese with an American accent
A hotel in Tysons needs to have meat and potatoes on the menu
it’s a Wagyu burger on a brioche bun with chili aioli and fries
or a grilled rib-eye steak with mushroom demi-glace and wasabi mashed potatoes
Raising and Educating Our Children During Uncertain Times
started out as a salesman in his native Japan
but went on to build an impressive culinary résumé
Surmising that his homeland’s societal structure was too limiting to allow him to pursue his dream of becoming a French chef
he moved to New York City to learn the craft at the Institute of Culinary Education
He later worked under famed chefs Masaharu Morimoto (who insisted he learn the intricacies of sushi making) and Nobu Matsuhisa
and was the executive chef at Zentan in Washington
he was the corporate chef for Ozumo Concepts International in Northern California
Wren’s menu is divided into raw bar items (including the aforementioned crudos)
Fortessa stoneware vessels provide a rustic backdrop for the chef’s sophisticated yet unfussy cooking
don’t miss his Tokyo chicken—large cubes of thigh meat marinated in soy
then fried until crispy and tossed with sake and koji
an umami-rich ingredient often used in Japanese cuisine
The nuggets rest on a bed of slaw and come with house-made pickles

Written by Yuki Matsuzaki and directed by Shiho Fukada
Mosaic Street celebrates the diversity of modern Japan
Yuki Matsuzaki has an old-timey but to-the-point thing to say about the oft-repeated idea that Japan is one of the most homogenous nations on the planet: “Hogwash.” A Hollywood actor of over 20 years
Matsuzaki has appeared in Letters from Iwo Jima
Pirates of the Caribbean: On Stranger Tides
The Pink Panther 2 and many other productions
his experiences also include the times he was told his height or hair didn’t look “authentically” Japanese
the actor concluded that the world has a too narrow definition of what it means to be Japanese
he decided to correct this problem the only way he knew how: through the medium of film
The result was the 2022 crime-drama short Mosaic Street
Written by Matsuzaki and directed by Shiho Fukada
it celebrates the diversity of modern Japan by casting openly transgender actress Kota Ishijima
openly lesbian actress Ami Ide and Afro-Japanese actress Ema Grace in the main roles
We recently talked to the cast of Mosaic Street to learn more about the movie and the current state of Japanese entertainment
Matsuzaki: I’d been aware of the lack of diversity in the Japanese entertainment industry for quite some time and always wondered what I can do to change that. When I saw Kota’s documentary The Butterfly
it made me wonder why a talented actress such as her wasn’t given a fair chance in the industry
I asked her casually if she would be interested in creating a demo reel to show her acting to the world
Then it came to my mind that I might as well represent the least represented minorities in the Japanese industries: transgender women
I asked Ami and Ema if they would be interested in joining the project
America and India while also attending 17 schools
I experienced prejudice when I was outside of Japan
I was also treated as an “outsider” because of my behavior
I’d been struggling with my sexuality since I was child
I was lonely for a long time and was impressed with [Yuki’s] passion in regard to minority representation in Japan
He truly understands the sensibility and the difficulty of being a transgender actress
Yuki’s typhoon-like ability to take action is second to none
Matsuzaki: I really hope Mosaic Street can change how people in the Japanese entertainment industry think of how minorities should be represented in movies and TV series
They should know that it’s fine to cast them for “normal” Japanese roles
They don’t have to find a “reason” to include them
Just cast them for whatever roles they have
then there are going to be more opportunities for minority actors in Japan and they will be able to become role models for minorities in Japan
Ide: I’ve always wanted to be the change I wanted to see in the world
I hoped Mosaic Street would give younger generations an idea that we can do whatever we want to do even if you’re not “normal” in Japan
Matsuzaki: The reason why the cast is speaking in both English and Japanese is that I wanted to prove to the world
that Japan is capable of creating compelling English-speaking content
If we start creating more content like this
I’m confident that Japan will be able to compete in the global market
Grace: I think this thinking came from what they teach at schools in Japan
I feel there’s always been a pressure that all students must be identical
Japanese schools deny the concept of diversity and force students to look and think the same way
I wonder how many parents in Japan teach their kids about diversity
It’s very rare for Japanese kids to be exposed to dolls or princesses or characters with dark skin like me
Most people have only seen the same skin tone and the same looking hairstyle since they were young
I suspect this childhood environment is also to be blamed for this misunderstanding of Japan being homogenous
Ishijima: Ever since Mosaic Street has been released on YouTube
the response by the people has been amazing
Some of the viewers did not know about us transgender actresses and were fascinated that we exist
I can expand our activities in various media outlets as an “actress.”
The Japanese entertainment world is quite backward and doesn’t take chances
Ide: I don’t know why we don’t see lesbian shows much
We don’t even see openly gay women in Japan
Maybe it’s because the film industry in general is dominated by men
I’m sure they are told by the industry that they can’t make it if they are openly gay
I remember one lesbian movie I saw and it was completely made by the male gaze
They need to start hiring more lesbian or female directors
Grace: Mixed-race Japanese like me are normally treated as foreigners
We’re not even allowed to audition for “Japanese” roles
I’d love to keep on playing “normal” Japanese characters
the current lack of diversity in the Japanese industry
Japanese viewers don’t even realize that what they see on screen actually lacks diversity
we exist and we see many ethnicities in Japanese classrooms
Unless they notice the discrepancy between what they are portraying in the media and what we see in reality
they’re not going to invite us to any auditions
Grace: I want Japan to accept its diversity and start creating movies and TV series that can compete internationally
I want to be part of that movement to make that dream come true
I want to appear in such diverse projects and I also want to produce myself
Ishijima: Just like in the world of Mosaic Street
even terms like “LGBTQ” won’t exist and we would be one
Ide: I’d never seen people like myself on TV in Japan because they were never cast in roles
I want kids to see me in some kind of art form (through music or in movies) and think it could be them
Remember when running your first-ever marathon seemed like a far-off goal? If you’re now looking to tackle two in one month, take a moment to acknowledge how far you’ve come—literally and figuratively. While non-runners may not understand your drive to double up, HSS physical therapist Yukiko Matsuzaki PT, DPT, OCS, SCS
certainly does: She’s an avid marathon runner herself
“While running back-to-back marathons is challenging
you get to experience the exhilaration of crossing the finish line twice
earn two medals and gain bragging rights all with one training cycle,” she says
You might also be looking forward to the travel
camaraderie and swag associated with the races you’ve selected
what you do between those marathons is of vital importance to your health
proper recovery is a priority and begins as soon as you cross the finish line,” says Matsuzaki
and they can positively influence your performance.”
She offers this advice for tailoring your recovery plan to ease out of one race and get pumped up for the next
The 60 minutes after your first marathon is a crucial stage of your recovery
so try to stay focused on cooling down and fueling up before you conk out from exhaustion
and stay warm as you head to the post-race recovery zone
Gentle stretching or foam rolling is sufficient
Stretching is a key component of injury prevention and can help prevent or limit delayed-onset muscle soreness
It’s important to replenish the carbohydrates
water and electrolytes you lost during the race
Within 30 to 60 minutes of finishing your first marathon
and eat a small meal consisting of a 4-to-1 ratio of carbohydrates to protein
Easy-to-digest examples of carbohydrates include bananas
Good choices for protein include smoothies
eat another healthy meal and keep the fluids coming
The seven days after your first race should be focused on recovery
which means taking it easier than normal while focusing on nutrition and sleep
While your mind will probably urge you to run
Dialing back training in this time period is just as helpful to your mental resilience as your physical recovery
Include plenty of lean meat or other lean protein to promote muscle repair
have high-quality complex carbohydrates for glycogen restoration and have healthy fats during meal prep or in whole foods like avocados.
Sleep is critical for restoring your body back to its pre-marathon state
It’s just as important for rebuilding at the cellular level as it is for recovering mentally and for feeling well overall
Aim for at least eight to nine hours of sleep per night
consider taking several naps during the day
Loosen up. Daily stretching exercises, yoga and foam rolling will facilitate soft-tissue recovery
schedule a massage within a few days after your race
Benefits of massage include increased circulation and blood flow to the muscles and reduced soreness
Having a deep tissue or sports massage with a certified massage therapist is recommended
Do some cross-training that focuses on light
nonimpact exercises like using the stationary bike and taking a relaxing swim
This will increase blood flow and further prevent your joints from getting stiff
If you’re aiming to PR at your second race
choose moderate-intensity interval runs over longer distance runs
If you have more than two weeks before your next marathon
Remember: You just ran a 26.2 mile “long run”—and you’ll also need time to taper
It’s important to have realistic expectations for your second marathon
think about what happened in your first marathon and what you might accomplish in the next one
if you crushed a PR during your first race
think of the second one as a leisurely run
If you used your first race as a test drive to work through jitters and race-day scenarios
then give it your all during the second event
listen to your body—during this race and in general
If the mind is willing but the body is not
walk away from your double-marathon month with your head held high and filled with lessons that you can apply next time

As opposed being "cured," having or being in a "remission" means that the condition symptoms could return
The physical circumstances that are considered to be a "remission" vary from disease to disease
A reoperation is a repeated surgery or additional surgery for the same condition
A reoperation may be done to correct a problem not fixed during the original surgery
or for new problems that occur as a result of the first surgery

The state school board plans to discuss education reform Tuesday
A revised federal law will transfer some power to individual states to determine how their schools should be reformed – and Hawaii principals want a piece of the action
Since last spring, the state has been preparing for the Every Student Succeeds Act
which is required to be fully implemented in the 2017-18 school year
Even as the state Department of Education and a governor’s task force pursue reform plans almost simultaneously
the principals have been holding their own forums to talk about what changes are needed in the islands’ public schools
“ESSA is really an opportunity for principals to have access to resources to help us to raise student achievement,” said Naomi Matsuzaki, a retired principal and Hawaii executive director of the National Association of Elementary School Principals
are “mentioned 167 times in the law.”
The principals hope they will be able to help their teachers and schools better understand why certain ESSA-related reforms are enacted and be more unified in carrying them out
and they may be making headway in having their input considered
ultimately creating a Hawaii “blueprint” for public education – from early learning to K-12 to higher education
Final drafts of both plans are set to be discussed at Tuesday’s Board of Education meeting and are meant to be incorporated into the state’s ESSA implementation plan
a document that needs to be submitted to the U.S
Department of Education in the spring to receive federal funding
The Every Student Succeeds Act replaces No Child Left Behind
a law that some principals felt was restrictive and punitive
principal of Washington Middle School in Honolulu
Under the old act, students had to be tested every year from third to eighth grades in math and English
They also had to be tested in science at least once in elementary
Schools were required to improve their students’ performance – in fact, the act required that students be 100 percent proficient in reading and math by the end of the 2013-14 school year – and their test results were tied to educators’ evaluations
“Half of my evaluation is not met because my test scores doesn’t meet the appropriate level of proficiency,” Harano said. “I’m the principal of the year
ESSA will transfer power back to the states to decide how schools should be held accountable and supported
how educators should be evaluated and how students should be tested
we feel that we have a better say in what we’re going to do – how is education going to be reformed,” Harano said
students will still need to be tested in the same grades and subject areas that NCLB required
but states can determine when and how they administer those tests
in addition to what kind of assessments they use
but to really be committed to what we are trying to do
we feel that we need to be involved in the total process
all the way to implementation.” — Michael Harano
states can set their own goals in measuring academic achievement
Taking advantage of the opportunity ESSA provides the states
the Hawaii Association of Secondary School Administrators and the Hawaii Elementary and Middle School Administrators Association teamed up to start holding the forums at the beginning of this school year
The group of 40 to 50 principals and vice principals focused on what they considered to be the seven main areas that the law is designed to support: curriculum standards
the group identified what an ideal situation would be
what prevents educators and students from reaching that ideal situation and a possible solution to overcome that challenge
Take school-level accountability as an example
could develop measures besides standardized tests to assess how their students are doing
school leaders don’t know much about the options available to develop their own system
By identifying why schools may struggle with developing their own accountability systems — and a solution to that problem such as providing training and mentoring for principals and teachers – leaders can make better decisions about what they decide to put in place
ESSA also requires that states adopt challenging academic standards in reading
math and science that are aligned to requirements to enter college and to technical standards
But teachers don’t have time to meet with other colleagues to help them deconstruct and implement curriculum standards and determine appropriate evaluations
is to have a system in every school where teachers can regularly meet with each other and a coach to better understand the standards and review their assessment data
they can figure out what instructional strategies would be appropriate to use
Principals at the forums said they want support in and outside the DOE because they often don’t know what’s allowed
principals seek support outside the DOE because community members tend to be more attuned to what’s going to work for their children
That’s something she did when she was principal of Kahaluu Elementary School
Community organizations were involved in having culturally appropriate programs within the school so students could understand and apply what they learned to real-life situations
The DOE and the governor’s ESSA task force also held meetings with community members and stakeholders
and while there were opportunities to participate
some principals felt their voices were not sufficiently heard
“It felt like something that was developed for me
not developed by me and my school,” Harano said at a recent Board of Education meeting where he gave a presentation on the group’s progress
chairman of the governor’s ESSA task force and a BOE member
said he supports the principals’ work because they’re doing it independently of the BOE
“We want to make sure that in the future that the system provides meaningful ways for teachers to have input
for the students to have input,” Galera said
While information and strategies resulting from the forums will be used by the principals and vice principals for planning at their own schools
the group also shared its results with DOE leadership so it can be part of the state’s ESSA plan
principal of Kalakaua Middle School and president of the Hawaii Association of Secondary School Administrators
I wanted to advocate that there would be a strong base for those 21st century skills that would naturally foster innovation and creativity in schools.” — Debra Hatada
assistant superintendent for the Office of Strategy
said information from the principal forums has been incorporated into the state’s strategic plan
said she attended meetings held by the DOE and the governor’s task force
Hatada said she wants to see the state’s accountability system look at the whole child
“When you think about innovation and creativity
it’s not only measured by achievement scores but a big part of having students who are innovative and creative is working on those soft skills,” she said
I wanted to advocate that there would be a strong base for those 21st century skills that would naturally foster innovation and creativity in schools.”

But running can also have some unexpected downsides in children
“Running is such a repetitive motion,” says Yukiko Matsuzaki, PT, DPT, OCS, SCS, a clinical specialist in orthopedic and sports physical therapy in Pediatric Rehabilitation at HSS
where you're performing different movements and going in different directions all the time
running is just one movement repeated over and over again.”
kids’ bones grow faster than their muscles lengthen
so their muscles are often tighter as a result
They can also have decreased coordination and weakness
All this adds up to an increased risk for injury
While research-based guidelines about kids and running are remarkably lacking
Here are some tips to help your child enjoy running injury free
encourage your kids to do the following exercises
One to three sets of 10 repetitions of each exercise (on each side if applicable) a few times a week is enough
Kids are more concerned with the newest and coolest and what’s on trend
but that’s not as important as choosing a shoe that matches their specific foot type
Matsuzaki suggests a visit to a specialty running shoe store
these stores have a treadmill on-site so they can watch your child run and recommend the best shoe to match their gait
it’s a good idea to bring a pair of their old shoes so the experts can evaluate the wear pattern on the tread
Kids are not great at delayed gratification
pulling a muscle or injuring a bone or joint
A dynamic warm-up before the run allows the heart rate to raise comfortably and gives the body a chance to ease into a sustainable running rhythm
“Stretching a muscle before exercise will actually hinder performance,” she adds
“Imagine a hair tie; if it’s overstretched
You need some tension to generate power and speed.”
Post-run stretching helps to loosen the muscles and joints and reduce soreness later
in which your child holds each stretch for 20 to 30 seconds
I think it’s really good for every runner,” Matsuzaki says
While many kid runners may be focused on maintaining a healthy weight
it’s also important that they get enough nutrients
“A low-calorie intake is highly correlated with injuries,” says Matsuzaki
but they need it to help their bodies recover,” she says
“I tell my athletes to aim for at least seven to eight hours of sleep
and even nine if they’re in competitive training season.”
While little research exists on the right distance to run for kids in each age group
Matsuzaki says that even the youngest runners can be involved in a 100-yard “fun run,” where little to no training is necessary
Most tweens can probably safely attempt a 5K
you also want to consider the total mileage of training
and not be pressured by coaches or parents
Each athlete is different in what they can handle
and it’s not just the physical that’s important
“Kids are under all sorts of pressures these days
so ideally running would not cause them more stress,” she adds
Metrics details
Here we show that repetitive quantum-like photorelease (uncaging) of glutamate induces a rapid and selective enlargement of stimulated spines that is transient in large mushroom spines but persistent in small spines
Spine enlargement is associated with an increase in AMPA-receptor-mediated currents at the stimulated synapse and is dependent on NMDA receptors
Long-lasting spine enlargement also requires Ca2+/calmodulin-dependent protein kinase II
Our results thus indicate that spines individually follow Hebb's postulate for learning
They further suggest that small spines are preferential sites for long-term potentiation induction
whereas large spines might represent physical traces of long-term memory

National Report
Actor Yoshitsugu Hattori came forward to say he was sexually abused as a child seven decades ago by the late talent agency impresario Johnny Kitagawa
adding a new twist to a sordid saga that is rocking the entertainment world
who accompanied Hattori at a news conference in Tokyo on July 15
said he suffered similar abuse at the hands of Kitagawa
the founder of Johnny & Associates Inc
who was an industry byword for nurturing male idols
What makes the latest revelations so startling is that the victims
the second son of noted composer Ryoichi Hattori
said Kitagawa performed oral sex on him when he stayed at his home
Hattori said he was sexually abused around 100 times by Kitagawa over the course of two and a half years
who helped his father’s activities immediately after World War II
was a frequent visitor to the Hattori home
Ryoichi Hattori received the People’s Honor Award after his death in January 1993
He said he was subjected to similar abuse--on 40 or 50 occasions over an 18-month period--when Kitagawa took him in his car to movies and plays
Hattori said he felt compelled to disclose his experience after seeing former members of Johnny & Associates talk about their anguish in public
“Japan’s entire entertainment industry should take the scandal more seriously,” he said
“We cannot bring this problem to a close unless legal measures are put in place to enable authorities to punish a crime as a crime.”

Fumikazu Matsuzaki saw his business take a one-two punch from the coronavirus pandemic
His 40-year career in the "hanko" seal game was put suddenly in peril when the traditional document formalization procedure became the target of criticism for its inherent inefficiencies
particularly as more people were forced to work remotely
Many in Japan called for the long-held practice of authorizing and formalizing documents via red stamped seals to be abolished
Then Matsuzaki lost his international revenue stream when sales of his tailor-made hanko for foreigners dried up due to a slump in visitors and tourists who normally ordered them as unique and personalized souvenirs or gifts
Forced to search for new business with his customers now stuck at home
Matsuzaki latched onto a novel idea: making digital hanko
"I was down in the dumps because you see something that you've done for 40 years suddenly labeled as 'not needed anymore,'" said Matsuzaki
a third-generation hanko shop owner in Tokyo
"But it's also true that I got out of that negativity and took a different look at life because of the hanko."
The spread of the novel coronavirus in Japan has prompted the government to call for more people to work from home to reduce the risk of infection
With an increasing number of companies acquiescing
hanko were thrust into the spotlight when complaints began surfacing from people forced to physically go to their office simply to make their mark on a contract or other document
Matsuzaki says the deep-rooted hanko tradition
should not be solely blamed for Japan's seemingly backward reliance on paper and ink
he acknowledges the time is likely ripe for reassessment
"I don't deny there may be cases in which hanko are not necessary
What needs to be done is to rethink what is necessary and what is not in Japan's hanko-dependent system," said the 61-year-old
the absence of hanko marks does not invalidate a contract unless specifically mentioned
including the powerful Japan Business Federation
to move toward a system in which digital documents can be considered official
governor of Yamanashi Prefecture in central Japan
was quick to express displeasure with the sudden shift
"Despite calls for electronic verification
I believe seals should be respected as showing the identity of an organization or a person or as a symbol of trust," the governor told a prefectural assembly session in June
Japanese use hanko seals to authenticate contracts and other important documents
a practice that some critics say has kept companies drowning in a sea of paper
It sells handmade hanko made by craftsmen who spend weeks carefully carving the delicate pieces
Japanese people often register such seals with authorities as a way of identification and use them on important occasions such as buying a house or car
and not all are laboriously carved by a person
more everyday hanko can be produced by machine in around half an hour at Matsuzaki's store
Matsuzaki says the pandemic has not caused a sudden change in demand for hanko at his store
apart from the drop off in customers from abroad
Japan was temporarily put under a nationwide state of emergency in April and May
with the government requesting that people refrain from nonessential outings
"I was worried (about the future) around April because hanko seals were being treated as something bad
"Then I thought I should make something people want to buy
Even though we are faced with this strong headwind at home
I thought I should spread the tradition more."
He decided to digitalize "dual hanko," or wooden stamps on which non-Japanese names are engraved in both Japanese kanji characters and the alphabet
Bunbukudo Inbo had sold around 800 wooden stamps since the launch of the series in 2017
would require no visit to the shop with no risk of coronavirus infection
Every hanko design is unique because he creates it based on a customer's choice of font and kanji characters that sound close to the original foreign name
Prices range from 2,750 yen ($25.70) to 3,300 yen
and Matsuzaki hopes the digital stamps can be used for various purposes
including profile pictures on social media
It is still uncertain how the debate over the hanko tradition will unfold and what it would mean to shops like Matsuzaki's in the long run
sales of Japanese hanko seals far exceed those of dual ones
who has not groomed anyone to take over from him in the business
I'd never gotten the idea of digitalizing dual hanko
"I will have to explore what I can offer as a hanko shop to society in the new era

If you're a skier, odds are at some point, you've taken a mighty spill. It's tough to avoid, even if you're an expert. "Skiing is a thrilling experience, but there are some risks," says Yukiko Matsuzaki
many injuries are related to factors that are within your control
like your physical conditioning or decisions you make on the slopes
particularly if you haven't been very active recently
try these tips to prepare your body for an injury-free trip
"Skiing requires a lot of endurance and strength," says Matsuzaki
It's important to begin working on it four to six weeks before your trip—not the week before
Stair climbing can be helpful because it recruits many of the muscles used in skiing
"Try to start at 10 to 15 minutes at a moderate pace
focus on the muscles that stabilize the knees: your quadriceps (front thigh muscle)
hamstrings (back thigh muscle) and glutes (butt)
"The best exercises that I recommend for skiers are things like squats
"You can use weights or bands to add resistance." She recommends one to three sets of eight to 12 repetitions
"If you don't have time to do all of it at the same time
you can always break it up into a few exercises one day and others the next."
hip activation exercises—do them for a few weeks before you ski again," she adds
These are helpful even if you're injury free
"Balance exercises are particularly important in skiing because you're on a slippery surface," says Matsuzaki
It's a matter of being able to adjust to quick movements or absorb uneven impact while keeping yourself upright
start by standing on one leg on a flat surface
you can make it more difficult by closing your eyes or standing on an uneven surface
(Just be sure you're ready before you progress.)
If you can't remember the last time your gear was checked to be sure it fits you properly
You should get your gear checked once a year
"You don't want your bindings too tight or too loose
either of which can cause injury." If your gear doesn't fit you anymore
can happen because your body cannot get into certain positions
or you're not flexible enough to move in a certain way
start by doing dynamic stretches like arm swings
warm up your whole body with jumping jacks
"Just enough to get your heart rate up," says Matsuzaki
easy runs—especially if you haven't been skiing in a few years
"A lot of people are inclined to start with the harder slopes so they don't waste their time," she adds
"But they can act as part of your warm-up."
Stretching at the end of your day is a good idea to loosen the muscles and joints
hip flexors and glutes—is so much better than doing nothing," she says
which means you hold the stretch for 30 seconds
put it in your bag or throw it in your car
It will help save you from so much soreness later on."
That goes for kids and beginner skiers too
but "it can help you learn the rules—not just of skiing
but also of the slopes and what the different signs mean and who has the right of way," says Matsuzaki
"These are all injury prevention strategies."
Learning to fall properly is also helpful in avoiding injury in all parts of the body
"Shoulder injuries are pretty common because in order to break a fall
most people will reach out and fall on an outstretched hand," she says
"A lesson can help you learn to avoid that."
Skiing takes up quite a bit of calories and energy
Things like fatigue and dehydration increase your chances of getting hurt
"A lot of injuries happen toward the end of the day
in that very last run that you want to squeeze in," says Matsuzaki
or stop." That also goes for tackling runs above your current ability level because friends are on them
or because you used to be able to do them with ease
As Hawaii’s 2013 Distinguished Principal (and a finalist for Island Insurance’s leadership excellence award)
the veteran educator and product of Castle High and Ben Parker Elementary herself came “down” from an administrative post to tackle struggling Kahaluu Elementary School a few years ago
and she has been harvesting crops of healthier scholars ever since
Principal Naomi Matsuzaki is surrounded by her family at the April 28 Distinguished Principal awards luncheon: (front
She and other state winners will be honored in October at the nation's capitol
And they’re edging closer to that name all the time
Kahaluu scored at 46 percent in reading proficiency and 37 percent in math
Now in “unconditional good standing,” her scholars’ 2013 scores at are an impressive 86 percent in reading
“Making the difference are the part-time teachers
vocabulary study and online practice for two hours each day,” she said
she lists other partners who support the school: Punahou’s Pueo program that brings 10 new Kahaluu scholars each year to its summer school
following up until they all graduate from Castle High; KEY Project and the adjacent city park for integrated academics
wellness and cultural programs; and a group of five area churches that donate supplies and extras whenever asked
Then there’s her enthusiastic parent resource teacher Melanie Asualo
who makes parents comfortable coming to campus; Eldean Kukahiko
who directs the ukulele band for pride and good music; her outstanding faculty
“It’s a great place to learn,” Matsuzaki said
“and I wanted to finish my career in a school where I love to be
It has everything here I need: My two grandchildren are being taught well
acceptance of all backgrounds – it’s been a wonderful journey.”
as daughter (and Kahaluu school parent) Wendy is principal at Waiahole Elementary
There’s still a lot of work to be done
My biggest challenge now is helping the parents understand the importance of attendance
We have the lowest attendance rate in the state
or are pulled out early for parents’ convenience
But it really disadvantages the kids and they cannot get that time back.”
As the choice of a panel of Hawaii school administrators
Matsuzaki will attend the National Association of Elementary School Principals’ conference in October in Washington
as well as a black-tie awards dinner and dance
“When I told my husband about the awards dinner
he said: ‘Do I have to wear a tuxedo?’ ” (The principal answered yes.)
One more plug for the ukulele band: Buy the May Day video for $5 at the school by Friday
and you can help fund their trip to Disneyland and California Adventure with King Intermediate School’s band
the scholars also will visit two area schools to share poi pounding
