講演1 大阪関西万博での熱中症シミュレーションと，ダムの事前放流最適化から探るデジタルツインとシミュレーションの活用
[Lecture1] Utilization of Digital Twins and Simulations Explored through Heatstroke Simulations at the Osaka-Kansai Expo and Optimization of Pre-Release from Dams
<REPORT>
本講演では、まず大阪・関西万博会場における熱中症リスク予測の取り組みが紹介され、3次元都市モデルと気象データを組み合わせたデジタルツイン・シミュレーションにより、会場内の暑熱環境を高精度に可視化し、日陰の確保や風通しを踏まえた対策に活用していることが説明されました。その後、熱中症指数を高さ別・場所別に予測することで、子どもや高齢者などへの配慮を含むきめ細かな対策が可能になる点が示されました。さらに、ダムの事前放流の最適化についても紹介され、気象予測の不確実性を考慮しながら、洪水リスクを抑えつつ渇水も防ぐ運用の重要性が述べられました。これらを通じて、現象や空間を精密にモデル化し、シミュレーション結果をもとに事前に対応を検討することが、防災・減災において極めて重要であると強調されました。
In the lecture, the efforts to predict heatstroke risks at the Osaka-Kansai Expo site were first introduced, explaining that by combining a three-dimensional city model with weather data in a digital twin simulation, the hot environment within the venue could be visualized with high accuracy and used to implement measures considering shade provision and airflow. It was then shown that predicting heatstroke indices by height and location allows for detailed measures, including consideration for children and the elderly. Furthermore, the optimization of pre-discharge from dams was also introduced, emphasizing the importance of operations that prevent both floods and droughts while taking into account the uncertainties of weather forecasts. Through these examples, it was emphasized that precisely modeling phenomena and spaces, and considering responses in advance based on simulation results, is extremely important for disaster prevention and mitigation.

[Lecture3] Advancing Flood Disaster Prevention through the Integration of AI and Simulation
スピーカー： 奥野 峻也 │株式会社構造計画研究所 気象防災ビジネス室 室長
speaker: Shunnya OKUNO ; President of Meteorological Disaster Prevention Business Office, KOZO KEIKAKU Engineering Inc.
<REPORT>
講演では、まず気象災害の激甚化・頻発化を背景に、従来の観測やハード対策だけでは対応しきれない水防災の課題が示されました。その上で、構造計画研究所が開発する、AIとシミュレーションを融合した洪水予測システムの考え方が紹介され、雨量や水位の観測データから力学的性質を保ったまま将来の水位を予測する手法が説明されました。特に、気象予報の誤差や不確実性を考慮しつつ、危険水位を超過する確率を示すことで、避難判断や初動体制の構築に役立てられる点が強調されました。さらに、熊川の事例などを通じて、従来より早い段階で危険を察知できる可能性や、自治体・河川管理者・民間企業の意思決定支援への活用が示されました。最後に、浸水シミュレーションをAIで高速化する技術にも触れ、災害時の状況把握、避難行動支援、リスクコミュニケーションへの応用可能性と、今後の社会実装への展望が述べられました。
In the lecture, first, against the backdrop of the intensification and increased frequency of meteorological disasters, issues in flood disaster prevention were presented, highlighting that conventional observation methods and hard countermeasures alone are insufficient. On this basis, the concept of a flood prediction system developed by the Structural Planning Laboratory, which integrates AI and simulation, was introduced, and a method for predicting future water levels from rainfall and water level observation data while preserving their mechanical properties was explained. In particular, it was emphasized that by indicating the probability of exceeding dangerous water levels while taking into account errors and uncertainties in weather forecasts, the system can be useful for evacuation decisions and the establishment of initial response frameworks. Furthermore, through examples such as the Kumagawa case, the potential to detect dangers at an earlier stage than before and its application in decision support for municipalities, river managers, and private companies was demonstrated. Finally, the lecture touched on technologies for accelerating flood simulations using AI, discussing the potential applications for situational awareness during disasters, support for evacuation actions, risk communication, and prospects for future social implementation.

スピーカー： 大路 剛 │神戸大学大学院医学研究科 感染症内科
speaker: Goh OHJI ; Associate Professor, Graduate School of Medicine, Kobe University
<REPORT>
本講演では、まず阪神・淡路大震災以降、日本の災害対応においてボランティア活動が重要な役割を担ってきたことが示され、その一方で、救援活動に伴う安全衛生対策の重要性が十分に理解されていない現状が指摘されました。その後、災害救援ボランティアが直面するリスクとして、外傷、感染症、熱中症、粉じんや石綿曝露に加え、強いストレスや代理トラウマなどの精神的負担が挙げられました。さらに、活動前の健康確認、予防接種、現地リスクの評価、自身の技能の把握など、事前準備の必要性が説明され、東日本大震災では津波、原発事故、化学物質、石綿など複合的な危険への対応が課題であったことも紹介されました。最後に、超広域災害時には行政だけでなく地域単位での支援体制や指揮体制の整備が必要であり、低技術・低電力でも機能する実践的な備えと、ボランティアを支える安全管理・メンタルヘルス支援の仕組みづくりが重要であると強調されました。
In the lecture, it was first shown that since the Great Hanshin-Awaji Earthquake, volunteer activities have played an important role in disaster response in Japan, while on the other hand, the current situation in which the importance of safety and hygiene measures in relief activities is not sufficiently understood was pointed out. Subsequently, the risks faced by disaster relief volunteers were listed, including trauma, infectious diseases, heat stroke, dust and asbestos exposure, as well as mental burdens such as severe stress and secondary trauma. Furthermore, the necessity of preparation, such as health checks before activities, vaccinations, assessment of local risks, and understanding one’s own skills, was explained, and it was also introduced that in the Great East Japan Earthquake, responding to complex dangers such as tsunamis, nuclear accidents, chemicals, and asbestos had been a challenge. Finally, it was emphasized that in the case of ultra-wide-area disasters, it is necessary to establish support and command systems not only administratively but also at the community level, and that practical preparedness functioning with low technology and low power, as well as the creation of systems for safety management and mental health support for volunteers, is important.

It was introduced that Mitsubishi Estate has been engaged for many years in urban development and the improvement of disaster prevention functions, mainly around Marunouchi, and the circumstances under which the shared rest space "Tomarigi" was launched as a new business in this context were explained. On top of that, issues in the modern work environment, such as work style diversification, presenteeism, sleep deprivation, and lack of breaks, were presented, and it was pointed out that conventional in-house rest rooms are not functioning adequately. Furthermore, it was stated that "Tomarigi" is conceived as a new welfare infrastructure supporting employees' productivity and engagement, not only through rest during illness but also via short breaks, refreshment, and care from professional trainers. Finally, the outlook was shared that, in addition to routine health support, the facility is intended to be developed as a place that can also function as a temporary evacuation and rest point for those in need during emergencies.
講演4 少子化という災害から、街のOSを書き換える
[Lecture4] Rewrite the city's OS from the disaster ofdeclining birthrates
スピーカー： 宮西 正憲 │神戸大学大学院医学研究科 小児科学分野研究者が創造造血幹細胞医療創成学 教授
speaker: Masanori Miyanishi ; Hematopoietic Stem Cell Biology and Medical Innovation Department of Pediatrics, Kobe University Graduate School of Medicine
<REPORT>
本講演では、まず少子化を単なる人口問題ではなく、災害時の「共助」を支える人そのものが失われる“静かな災害”として捉える視点が示されました。その上で、人口減少はインフラ、社会保障、地域文化の崩壊をもたらし、特に東京一極集中と婚姻数・出生率の低下が全国的な持続可能性を損なっていることが説明されました。さらに、医療分野でも人材不足、介護不足、医薬品の海外依存、ドラッグラグなどにより、医療インフラの崩壊が現実味を帯びていることが指摘されました。その後、こうした危機に対する対応として、神戸市の都市戦略や神戸医療産業都市の蓄積を踏まえ、医療・研究・産業を結びつけた新たな都市OSの必要性が論じられました。最後に、増血幹細胞研究を核とした治療開発、研究拠点整備、デジタル化、若い世代を巻き込む共創の取り組みを通じて、神戸から未来の都市モデルを創出していく可能性が示されました。
In the lecture, it was first suggested that the declining birthrate should be viewed not merely as a population issue but as a 'silent disaster' in which the very people who support mutual aid in times of disaster are being lost. On this basis, it was explained that population decline brings about the collapse of infrastructure, social security, and regional culture, and that the concentration of population in Tokyo along with the decrease in the number of marriages and birth rate is particularly undermining the sustainability of the nation as a whole. Furthermore, it was pointed out that in the medical field as well, shortages of personnel and caregiving, dependence on overseas pharmaceuticals, and drug lag are giving a realistic threat of the collapse of medical infrastructure. Following this, as a response to such crises, the necessity of a new urban OS connecting medical care, research, and industry was discussed, taking into account Kobe City's urban strategy and the accumulation of the Kobe Medical Industrial City. Finally, it was suggested that through initiatives such as treatment development centered on hematopoietic stem cell research, the development of research bases, digitalization, and co-creation involving the younger generation, there is potential to create a future urban model starting from Kobe.
