Congratulations! Akutsu-san was awarded Outstanding Presenter Award in JSCE 2024 Annual Meeting (令和6年度土木学会全国大会 第79回年次学術講演会優秀講演者). His presentation was titled "構造ヘルスモニタリングが橋梁維持管理費用に与える効果の基礎的検討".

Congratulations on Hasegawa-san's tremendous efforts and well-deserved success in his PhD defense. Wishing Hasegawa-san continued achievements in his future endeavors.

JSCE 2024 Annual Meeting was held at Tohoku University, 2-6 September. Akutsu, Chen (Debao), Fei, Hiro, Irawan, Kawabe, Ma, Sugimoto (graduated in 2024 Spring), Ueno, and Wang presented their research findings at the Meeting.

In August 2024, we began the experiment in Northern Ireland, UK, aimed at expanding the overseas deployment of our lab's scour monitoring system. This experiment was conducted by our lab member, Daigo Kawabe with the support of the Japan Society of Civil Engineers' Infrastructure Management Technology International Deployment Research Grant. The experiment is being conducted with the cooperation of Queen's University Belfast and Fuji Electric Co., Ltd. 常時洗堀モニタリング技術の海外展開に向けて、2024年8月に、英国北アイルランドの石造りアーチ橋で長期計測を開始しました。 これは、研究室所属の河邊大剛氏が、土木学会インフラマネジメント 技術国際展開研究助成を受けて行なっているものです。 本実験には、QUB大学と富士電機(株)の協力を受けています。

15th International Workshop on Advanced Smart Materials and Smart Structures Technology (ANCRiSST 2024) aims to provide a forum to discuss the current progress and state-of-the-art techniques in structural health monitoring, in data-driven structural analysis, advancement in structural experiment, and smart materials. The workshop has encompassed a wide range of topics including structural dynamics, structural control, smart structures and materials, structural health monitoring, damage detection, performance evaluation of aging infrastructure, physics-informed artificial intelligence, and innovative approaches to structure maintenance.

2024 Asia-Pacific-Euro Summer School on Smart Structures Technology (APESS 2024) is an intensive three-week programme organised by the Graduate School of Engineering, Kyoto University, consisting of coursework, lectures, laboratory exercises, technical visits and cultural activities. The programme includes lectures by world-leading experts in the fields of civil engineering, structural dynamics and control, smart structural technology and structural health monitoring, as well as a capstone competition, allowing students to consolidate the knowledge gained during the summer school.

From May 17th to 19th, 2024, Professor Sun Limin , Professor Xia Ye , and postdoctoral researcher Lu Xuzhao attended a three-day academic exchange meeting at Kyoto University in Japan at the invitation of Professor Kim Chul-Woo. The JSPS collaboration project will last for three years, looking forward to further communication in the future.

Our lab member, Debao Chen, attended the 4th International Conference on Vulnerability and Risk Analysis and Management & 8th International Symposium on Uncertainty Modelling and Analysis (ASCE-ICVRAM-ISUMA), held on April 25-27, 2024, at Tongji University, Shanghai, China.

He made a presentation entitled Bayesian Inference for Bridge Model Parameter Estimation Utilizing FNO-Based Surrogate Models.

Mr. Katsunori Yasui introduced the activities of SHO-BOND & MIT in the USA.

Mr. Daniel Hein who is CEO of LATODA presented about image processing for damage detection.

Thank you, Mr. Katsunori Yasui and Mr. Daniel Hein, for your time, expertise, and generosity in sharing your knowledge with us. We look forward to prospective future collaborations.

Prof. Kim has been selected as a fellow of Cheney Fellowship at University of Leeds in december 2023.
