Professor Tadahiro SHIBUTANI was appointed as the director of the center for creation of symbiosis society with risks in Yokohama National University.
The mission of the center is to systematize social implementation in a risk-symbiotic society as an academic discipline. There are various risks in modern society, and we need to manage the society in harmony with the risks. Although prompt social implementation of science and technology is required to solve social problems, an appropriate methodology has not been established at present.
Under the leadership of former Director Kazuhiko Noguchi, we have contributed to a wide range of social implementation activities such as the formulation of various domestic and international standards and guidelines related to risk symbiosis. After four and a half years of activities, issues that are difficult to implement in society by the university alone have become clear, and from 2020, the NPO Risk Symbiotic Society Promotion Center will be established to promote a wider range of social implementation activities. It’s a schedule.
The center will expand to the world as a research base for a new academic system originating from the university in order to realize the desired social image. We look forward to your continued support and cooperation, and we look forward to the participation of those who agree with the purpose of this center’s activities and work together.

Risk management is a systematic approach to managing any type of risk. According to ISO 31000:2018 “Risk management — Guidelines”, the purpose of risk management is to create and protect values and eight principles are required to perform effective risk management.
The interesting point of ISO 31000 is the definition of “risk”. In ISO 31000, risk is defined as “effect of uncertainty on objectives”. An effect is a deviation from the expected and can be positive, negative or both. This concept is suitable for modern society with risks.
Professor Shibutani is currently an expert of TC262 which is managing ISO 31000 series and dedicating to research and education of risk management.

Highly accelerated limit test (HALT) is a qualitative accelerated method for testing electronic products as introduced in IEC62508. The purpose of HALT is to identify specific failure modes of units by generating external stresses. HALT has been adopted for many products, and some companies use HALT to improve the design process of their products. However, failure mechanism of products during HALT is too complex, and it is not easy to identify a problem in the tested product.
The goal of our group is to identify fundamental failure mechanisms of products during HALT.
