   Title：INVESTIGATION ON A METHOD OF COUNTING LOW-CYCLE FATIGUE IN STEEL UNDER CRACK CLOSURE AND RANDOM VARIABLE AMPLITUDE LOADING
   Summary: The over design in low-cycle fatigue is one of the most significant problems in the safe and financial design of nuclear power plants. As a crack propagates, a crack closure effect occurs, which is considered one of the reasons for making the prediction of a fatigue life short. In this research, the Second Order Differential of P (SODP) methodology was proposed as a simple method to determine the crack opening point and introduce it into the design. This methodology has succeeded in reducing the maximum error of 15% in the current methodology to 9%, and has also reduced the waveform dependence of the life prediction.
5. Your impression & future plan:
   In receiving this award, I would like to express my deepest gratitude to Professor Kawabata, members of Tokyo Electric Power Company Holdings, Inc. who collaborated with me, laboratory staff, and other people who supported me. I am very grateful to receive this prestigious award in recognition of my research during my master’s degree. Although this research has successfully improved the accuracy of low-cycle life prediction by mitigating the crack closure effect, there are still many issues to be clarified, such as the precise definition of the crack opening point and the effect of microstructure on low-cycle fatigue. I will do my best to live up to the honor of this award.

3. Name of award and short explanation about the award:
   The Society of Advanced Materials and Process Engineering (SAMPE) Student Bridge Contest World Championship is an annual competition for lightweight bridges made of fiber-reinforced composites and is divided into eight categories based on the type of reinforcing fiber and bridge shape. The University of Tokyo team won the 2023 competition in Category B (hollow rectangular cross-section bridge using carbon fiber). This is the second year in a row that our laboratory has won.
4. About awarded research:
   The winning team of the Japan competition is sent to this world competition as the representative of Japan. Takahashi-Wan Laboratory had won the Japan competition for the past four consecutive years and the world competition for the last year. After the optimal structural design by FEM utilizing the anisotropic properties of carbon fiber, we repeated the molding and evaluation tests by hand many times and entered the world competition with our best bridge, which was estimated to have the smallest strength variation based on appearance and sound diagnosis.
5. Your impression & future plan:
   We are very honored to receive this award. We would like to express our deepest gratitude to the members of our laboratory for making it possible for us to receive this award. We did the best we could do at the moment, but we feel fortunate to have won against world-class universities which are regular winners of this award. We gained valuable insights and advice from the interaction with these universities, and we will continue to improve our design and molding techniques to pass them on to the younger members of our laboratory.

Tatsuki Yotsushima (M2, Kawasaki lab) won Logistics Research Encouragement Award at the Japan Logistics Society.

〈Name of award and short explanation about the award〉
The Logistics Research Encouragement Award, awarded by the Japan Logistics Society, is given to outstanding young logistics researchers who have achieved particularly outstanding results enrolled in educational and research institutions to which at least three regular members of the Japan Logistics Society belong.

〈About awarded research〉
This study developed a time-series supply chain network (SCN) using global inter-firm transaction data and clarifies the robustness and structural characteristics of the SCN. Besides, robustness of the network to various risk events and the aspects of functional deterioration were identified. We also found the conditions to enhance the functional sustainability of supply chain, and contributed to the formulation of strategies that firms should take in response to risks. As one of the risk events, we consider the US-China trade friction and analyzed a case in which all semiconductor transactions between the US and China were disrupted. In addition, we proposed a new indicator of network overlapping rate as a method for creating time-series SCNs.

〈Your impression & future plan〉
I would like to express my deepest gratitude to Dr. Kawasaki and all those who supported me in receiving this award. I am proud to receive such a prestigious award in recognition of my research activities and achievements during two years in the master’s course. In the Kawasaki Lab, I have had diverse, unique, and fulfilling experiences, such as daily research activities, readings, seminars, submitting papers to journals, presentations at international conferences, and joint seminars with other universities. Although I will be leaving the university, I will continue to make efforts to contribute to society.

On 10/21/2022, Students from Takahashi/Wan Lab Win Double in Two Categories of the 2022 IHI/SAMPE Japan Student Bridge Contest 　Category B (Peng Xue (D2), Yuanyuan Wu (Visiting D), Zhengyang Zhu (M2), Qiujun Wang (M1), Ayumu Uno (B4)), Category G (Weizhao Huang (D2), Zhiyu Wang (D1), Tomotaka Suzuki (M1), Fan Zhang (M1), Shingo Miyamoto (B4)) ＜Name of award and short explanation about the award＞ The Society for the Advancement of Material and Process Engineering (SAMPE) Student Bridge Contest is an annual world competition (about 100 participating teams) for lightweight bridges made of fiber-reinforced composite materials. The University of Tokyo team won in two categories at the Japan preliminary round (17 teams participated) held on October 21, 2022. ＜About awarded research＞ The Todai team won Category B (in which carbon fiber, bridge shape, and forming method used are specified) for the fourth consecutive year, and won Category G (in which materials used, bridge shape, and forming method are not specified) for the first time. We will be sent to the world competition to be held in the U.S. next spring. ＜Your impression & future plan＞ We are very honored to receive these awards. We would like to express our deepest gratitude to the people in our laboratory for their support in helping us win these two awards. We expect that many teams will bring their state-of-the-art bridges to the 2023 World Championships after Corona leaves, but we will continue to make improvements and aim to win prizes.

On 09/20/2022, Naoki Kosuge (graduated Dept. of Systems Innovation in March 2022), Ryuichi Shibasaki (Assoc. Prof., Resilience Engineering Research Center/Dept. of Systems Innovation), Koki Kawachi (M1, Dept. of Technology Management and Innovation), Hirofumi Arai (Economic Research Institute for Northeast Asia), Takefumi Nakamura (graduated Tokyo University of Marine Science and Technology in March 2022), Lei Liu (doctoral research student, Dept. of Technology Management and Innovation) in March 2022 won “OCDI Takeuchi Yoshio Logistics Award” at the 9th International Conference on Transportation and Logistics (TLOG 2022). ＜Name of award and short explanation about the award＞ OCDI Takeuchi Yoshio Logistics Award ( https://tlog2022.inu.ac.kr/call-for-papers/ocdi-takeuchi-yoshio-logistics-award ) is awarded for the best paper selected from those submitted to the International Conference on Transportation and Logistics (TLOG, https://tlog2022.inu.ac.kr/home), which is held every two years. ＜About awarded research＞ The awarded paper titled “Development of Multicommodity-type Global Logistics Intermodal Network Simulation Model Including Both Containerised and Dry Bulk Cargo” logically integrated the bulk cargo (i.e. iron ore and coal) shipping into the existing global logistics intermodal network simulation model which focused on container cargo. Therefore, the paper was highly evaluated because the transportation form and trade pattern of these cargo are completely different but the competition in capacity of land transport may be observed. ＜Your impression & future plan＞ I am very honored to receive the OCDI Takeuchi Yoshio Logistics Award. I would like to express my sincere gratitude to Prof. Shibasaki, Mr. Kawachi, and other co-authors for their tremendous efforts in additional analysis and revising of the paper.
