It is important to prevent and reduce injuries caused by accidents that we encounter in our daily lives, such as falls, traffic accidents, etc., to keep the quality of life. In addition, the development of prevention, diagnosis, and treatment of cardiovascular diseases is necessary to extend healthy life expectancy. Engineering can make a significant contribution to the treatment of injuries and cardiovascular diseases. In addition to providing safety and security through engineering, we will consider mechanisms and services for its wide use.
