[Lecturer] Taku Ito, Partner, Mori Hamada & Matsumoto Foreign Law Joint Enterprise Yoshifumi Nagakubo, Senior Associate [Key Lecture Content] As we move towards a carbon-neutral society, the large-scale introduction of renewable energy sources is progressing, making the enhancement of market design that balances stable electricity supply and economic efficiency an urgent issue. In this context, the "simultaneous market," which integrates the trading of electricity (kWh) and adjustment capacity (ΔkW), is being discussed as a core component of future electricity systems, and serious considerations for its implementation are underway. In this lecture, a lawyer who has led discussions at the forefront of national system design will explain in an easy-to-understand manner the background and necessity of the simultaneous market, as well as the overall picture of its complex mechanisms, based on practical experience. Furthermore, the lecture will clearly outline the latest developments in current discussions, realistic challenges for implementation, and prospects for future electricity business in Japan, incorporating perspectives and insights as a system designer and practitioner.

[Instructor] Hirokazu Shibata, President and CEO of ZAZU Design Co., Ltd. [Key Lecture Content] As the importance of heat dissipation design increases in daily operations, it is necessary to study a range of books on thermal engineering to learn the overall picture of heat dissipation design. However, books on thermal engineering typically start with the basics of heat transfer and cover topics such as temperature boundary layers and dimensionless numbers related to heat transfer, making it quite difficult for beginners to grasp the overall picture in a short period. This seminar is aimed at engineers who will begin thermal design in the future, focusing on various heat dissipation devices as specific subjects. The goal is to understand the basics of thermal design while learning about the characteristics and usage of these heat dissipation devices. After attending this seminar, participants are expected to acquire knowledge equivalent to that gained from studying a range of thermal engineering books. [Lecture Topics] 1. Current Status and Challenges of Thermal Design 2. How "Thermal Resistance" Determines Heat Dissipation Pathways 3. Fundamental Laws Governing Heat Transfer 4. Air Cooling through Heat Transfer 5. Heat Diffusion through Thermal Conduction 6. Heat Transfer via Two-Phase Flow of Gas and Liquid 7. Q&A Session
