“Japanese Kimono Culture”
“Zazen (Zen meditation) experience”
The Center for Global Education and Japanese Studies(CGJ) hosted “Doshisha Summer Session 2024” conducted face-to-face for four weeks, from July 9 to August 6. This program was held at the Imadegawa campus in Kyoto for the first time in eight years, with 18 participants from China, the Czech Republic, Taiwan, and the United States.
In addition to Japanese language classes, the program offered classes on traditional culture and daily life in Kyoto, as well as off-campus classes to experience Kyoto and Japanese culture, including the Gion Festival.
With the aim of furthering the study of Japanese traditional culture, special classes by 10 guest speakers were also carried out. On the final day, each student gave a presentation in Japanese on a theme set according to his or her own interests.
During the period, more than 50 students (Both Students belonging to Doshisha University and Doshisha Women's College of Liberal Arts) also participated in classes as volunteer study partners, joining in conversation practice and other activities.
Students learned that there are people who are making great efforts with pride, love, responsibility, and a sense of duty to carry on Kyoto's traditional events and Kyoto's traditional industries, which are in danger of extinction. In addition, it was a unique experience for them to step into a traditional Kyoto machiya house, and they learned more than just “a cultural experience”

From March 1 (Friday) to August 8 (Thursday), 2024, German Language and Intercultural Studies EU Campus Program 2024 was held at Doshisha EU Campus at Tübingen University. 15 students from Faculty of Letters, Faculty of Law, Faculty of Culture and Information Science, Faculty of Science and Engineering, Faculty of Global and Regional Studies participated in the program.
Right after the program started in March, the students took intensive German courses for Doshisha students including several field trips and an elementary school visit, which contributed greatly for improvement of their German proficiency. From the middle of April, they started to study German language by proficiency level together with UT international students from various countries and regions, and experienced a diverse of intercultural communication. In addition to German language classes, the students deepened their understanding of German and EU society and culture through Joint Seminar- Intercultural Studies classes with UT students from Department of Japanese Studies and special lectures by Doshisha faculty members on EU Campus.
In extracurricular activities, the Buddy Program was implemented also in 2024, where Doshisha students and UT Japanese Studies students are paired up as a TANDEM partner. While learning each other’s language, the students sometimes went beyond the framework of a "Buddy Program" and deepened exchanges on and off campus, either individually or in groups. It is supposed that a part of Buddy students of the Japanese Studies would go study abroad at Doshisha from Spring 2025. Therefore, we are expecting that their friendship would continue and bloom up next year in Kyoto.
Lastly but not at least, we could not realize this program in such a successful way without diligent effort and great contribution by the relevant persons and institutes of UT, especially by “Deutsch als Fremdsprache” and “Department of Japanese Studies.” We would like to take this opportunity to express our sincere gratitude for all involved in UT for this wonderful program.

Surface-energy ratchet mechanism The proposed ratchet mechanism utilizes the asymmetry in surface wettability between the smooth and rough faces of the teeth of a geometrically symmetric gear to achieve ratcheting motion. .
The research team, including Dr. Dai Matsuda, a former doctoral student, Jiro Senda and Eriko Matsumura, professors at the Faculty of Science and Engineering, revealed the mechanisms behind wall film formation, which is a crucial contributor to particulate matter emissions under cold fuel conditions.
Particulate matter emissions from direct injection engines are a major environmental issue. Matsuda and his colleagues studied how wall films, which form when fuel sprays onto engine walls, contribute to these emissions in cold conditions. They found that cold fuel creates thicker wall films, producing more particulate emissions. This finding will help develop improved fuel injection methods, making engines cleaner and helping to attain the upcoming Euro 7 emission standards.

Surface-energy ratchet mechanism The proposed ratchet mechanism utilizes the asymmetry in surface wettability between the smooth and rough faces of the teeth of a geometrically symmetric gear to achieve ratcheting motion. .
Researchers, including Miku Hatatani, a Ph.D. student in the Department of Chemical Engineering and Materials Science, have developed a novel ratchet mechanism that utilizes asymmetry in surface wettability and resembles the biological Brownian ratchets
Conventional ratchet mechanisms involve a geometrically asymmetric gear for realizing the ratcheting mechanism. In a new study, researchers have now developed a novel ratcheting mechanism based on the asymmetry of surface wettability and it uses a geometrically symmetric gear. This innovative mechanism resembles the Brownian ratchets, which have been proposed for understanding the motion of molecular motors in biological systems and can pave the way for novel energy-harvesting technologies.

Comparison of the wet-bulb globe temperature (WGBT) among different surfaces The on-site WGBT values are significantly higher than those measured by the Japan Meteorological Agency weather station, particularly for hard and sand-filled artificial grass courts, highlighting the need for appropriate countermeasures. .
Researchers, including Hiroki Yamaguchi, a PhD student at the Graduate School of Health and Sports Science, investigate the thermal environments of different tennis court surfaces, offering key insights for effective heat countermeasures
Tennis players are exposed to high-heat environments during matches. Different tennis court surfaces can have different thermal environments, necessitating suitable countermeasures. In a new study, researchers investigated the thermal environment of different tennis court surfaces using on-site measurements and compared the results with the established guideline levels. Their findings can lead to enhanced countermeasures, thus improving the safety of athletes, coaches, referees, and spectators.

Effects of eccentric-only resistance training on hamstring muscle stiffness, size, and strength
Eccentric-only resistance training at long muscle lengths and with a long contraction duration can chronically decrease the passive stiffness of a specific muscle while simultaneously increasing its size and strength.
Raki Kawama, an Assistant Professor at the Organization for Research Initiatives and Development/Faculty of Health and Sports Science, and his colleagues suggest that resistance training boosts muscle size and strength while reducing passive muscle stiffness.
It is commonly believed that resistance training, widely recommended for building muscle strength and size, may increase passive muscle stiffness. However, they have demonstrated that eccentric-only resistance training, particularly when performed at long muscle lengths with prolonged contraction durations at high weekly frequencies, can significantly reduce passive muscle stiffness in specific muscles while simultaneously increasing strength and size. This innovative training method can significantly benefit athletes and patients in sports and rehabilitation settings.

Generating adversarial images for image cropping models Many commercial image cropping models utilize saliency maps (also known as gaze estimation) to identify the most critical areas within an image. In this study, researchers developed innovative techniques to introduce imperceptible noisy perturbations into images, thus influencing the output of cropping models. This approach aims to prevent essential parts of images, such as copyright information or watermarks, from being inadvertently cropped, thus promoting fairness in AI models. .
Researchers, including Masatomo Yoshida, a Ph.D. student at the Graduate School of Science and Engineering, techniques to create perturbations in images that can deceive cropping models, helping identify and address their weaknesses.
Models that automatically crop images, like those used in social media to create thumbnails, can sometimes make mistakes, leading to misrepresentation. To study and address these models' weaknesses, they have developed novel methods for creating adversarial examples. By efficiently generating adversarial images that modify actual images to 'trick' models into cropping different regions, these techniques aim to make image cropping AI systems more reliable and fair.

For some, it was the first time sewing in a long while, so students helped each other with the sewing process.
Although tying the string was challenging, we persisted and successfully completed our OMAMORI!
After that, we threaded the tied string through the hand-made OMAMORI.
Everyone enjoyed chatting and creating beautiful OMAMORI together.

Proposed ultrasonic liquid crystal light diffuser Schematics of the LC molecular orientation and the transmitted light in the absence (left) and in the presence (right) of the ultrasound excitation. Red and blue curves represent the light and the ultrasound vibration, respectively .
Professor Daisuke Koyama and graduate students, Yuma Kuroda and Ryoya Mizuno, from the Faculty of Science and Engineering developed a novel tunable ultrasonic liquid crystal light diffuser that allows changing the diffusion direction.
In conventional light diffusers, optical characteristics such as diffusion angle and direction can only be tailored during fabrication and not after installation. Light diffusers that allow such changes can save energy and provide better indoor lighting aesthetics, but such devices are rare. In a new study, they have developed a novel tunable ultrasonic liquid crystal diffuser, that allows changing the diffusion direction using electrical inputs, while having a compact structure with no moving parts.
