Paper of Associate Professor Masahiko Hashimoto et al. of the Faculty of Science andEngineering Featured on the Cover of Electrophoresis for the Second
An article of the research group of Associate Professor Masahiko Hashimoto(Department of Chemical Engineering and Materials Science, Faculty ofScience and Engineering) and others was published in Electrophoresis(Special Issue: Microfluidics and Miniaturization 2018) on February 2, 2018.
This is the second consecutive year that an article from this group has been
selected for the publication’s front cover.
The article demonstrated a new microfluidic technique, in which a
microfluidic chip made of the silicon resin polydimethylsiloxane (PDMS) andseveral glass or plastic plates are bonded using only the viscoelastic propertyof PDMS and degassed for a certain time, enabling rapid automatic creationof monodisperse water-in-oil emulsion droplets (about 500 droplets persecond) only by dropping oil and water phases in the microchannel entrance.
This is almost the easiest, fastest and cheapest production technique ofmonodisperse emulsion droplets to date, which is expected to be applied tovarious biochemical analysis and functional materials production using liquiddroplet.

Professor Daisuke Koyama (Faculty of Science and Engineering) Develops
Ultrathin Lens for a Smartphone Camera
Professor Daisuke Koyama (Department of Electrical Engineering, Facultyof Science and Engineering), et al. developed a 1.5mm smartphone camera
lens. With this lens, focal length can be freely adjusted using ultrasonicwaves and liquid crystals, eliminating the need for moving parts. Therefore,
this technology is expected to enable the design of even thinner smartphones
in the near future.
The development of this lens was introduced in the Nikkei (newspaper) on
June 4, 2018.
Further information can be found in the journal Applied Physics Letters.

Professor Shizuko Hiryu (Faculty of Life and Medical Sciences), et al. discover that bats
avoid interference by shifting their echolocation call frequencies
ConsecutiveYearProfessor
Shizuko Hiryu,
graduate student Kazuma Hase and others of the Faculty of Life and Medical Sciences
discovered that bats avoid interference by adjusting the frequencies of their echolocation calls among themselves
when flying in a group.
Bats possess a sophisticated sonar1 system, which enables them to fly even through a dark narrow cave without
colliding with each other, although a situation could theoretically arise where their echolocation calls interferewith those of other bats when flying in a group. How bats avoid interference from the echolocation calls of otherbats had not been clarified.
Hiryu’s group developed a system that can measure the sound emitted by each bat during flight by placing atelemetry microphone2 on multiple bats. It was discovered that bats avoid interference by adjusting the frequencyof the sound emitted to obtain information about their surroundings.
This finding demonstrated that bats can be a new model animal for studying group behavior and swarm
intelligence sensing3. In the future, it is expected that studying bats’ simple algorithm for avoiding interference
will lead to ideas for new technology, such as group control of autonomous sensing robots.
This research achievement was published in the Communication Biology on May 3, 2018.

The research result of Professor Noriko Koizumi and Associate Professor Naoki
Okumura of the Faculty of Life and Medical Sciences, et al. made it possible to conduct
the world’s first regenerative therapy clinical study for corneal endothelial dysfunction,and its outcome was published in one of the world’s most prestigious medical journals,
The New England Journal of Medicine.
In the article, the group reported the efficacy and safety of cell injection therapy after aclinical study of 11 patients over two years. The study started in December 2013 usingtechnology established at Doshisha University.
It was jointly conducted with the Department of Ophthalmology of Kyoto Prefectural
University of Medicine (Professor Shigeru Kinoshita, Lecturer Morio Ueno, et al.)(published in March 15, 2018)
The research result was introduced in The Kyoto Shimbun, etc.

Fumika Takeji (Graduate School of Law) Receives Ikuo Onaka Family Law
Incentive Award for New Researchers
Fumika Takeji (Doctoral Program, Graduate School of Law) received the 19th Ikuo Onaka
Family Law Incentive Award for New Researchers, with her two articles published in ‘Doshisha
Legal Studies’. This award is offered to new researchers who have presented outstanding
articles in the field of family law. Besides commending their achievement, the award is also
expected to encourage their future research activities. The awardees are selected once a year byfive committee members, including Professor Emeritus of Tokyo University, Akira Yonekura.

Takeji, focusing on the freedom and confinement of succession in the case of inheritance,
deliberately introduced and analyzed legal precedents in Germany with themes of whether thefreedom of decision of a right-holder of a legally reserved portion is restricted in relation to acreditor, and also in the case where alimentation or social assistance is involved. Takeji washighly commended for providing a new perspective on an issue that had not been fully discussed in Japan.

Awarded articles:‘Freedom of decision of a right-holder of a legally reserved portion and protection of creditors in German laws’‘Freedom of decision of a right-holder of a legally reserved portion and life security in German laws’

Report: “World Kitchen ～Ehomaki, Japan～” (presented by SIED)
On January 12th (Fri.), SIED hosted "World Kitchen ～Ehomaki, Japan～" at the Faculty Lounge LIBRE on Kyotanabe
campus. In this event, participants learned a traditional Japaneseevent “Setsubun” through making Ehomaki (sushi-roll) andeating beans.
To start off the event, SIED staff introduced unique sushi
around Japan, and explained “Setsubun”. Participants followed
the custom and ate as many beans as their age. After that, wemade Ehomaki with shiitake mushroom, cucumber, egg, andpink fish floss. Although participants struggled with rollingsushi at first, everyone was able to make nice Ehomaki. In theend of the event, we ate them toward the south-southeast (goodluck direction in 2018) and wished for a healthy year.

Report: "World Kitchen ～Rice cooked in local bamboo～" (presentedby SIED)On May 13th (Sun.), SIED and the International Exchange
Association in Kyotanabe co-hosted “World Kitchen ~Ricecooked in local bamboo~” at Bio Tatara, an old Japanese folk
house style cafe. 17 people including international students, local
students and the association members joined the event.
Kyotanabe city is famous for bamboo, and May is the best season
for bamboo shoot, so we cooked takenoko-gohan, bamboo
shoot-rice. We prepared bamboo containers and steamed rice in it.
Although participants struggled with controlling the fire,
everyone helped each other and enjoyed the cooking. The staff of
Bio Tatara also prepared bamboo shoot tempura and miso soupfor us, we tasted them with takenoko-gohan. Despite the fact that
it was raining on the day of the event, the word “delicious!” fromparticipants made us so happy. We hope that the event will be agood memory for all the participants. After cooking, the staff ofthe association and Ecomana@Kyotanabe, one of the projectgroups in Doshisha introduced interesting stories about Japaneseand Taiwanese bamboo. We also held a small quiz competition
about their story. Some participants got a prize. Before ending theevent, the staff of Bio Tatara took us around the Japanese old folk
house.
