- Self-introduction
- Study of a chrono-nutrition and chrono-exercise from a view of the human circadian system. Study on estimating the daily energy expenditure of firefighters required to carry out high-load activities in disaster and the effects of the evacuees' sleeping environment on sleep quality. Recently, a study on the effects of the three components of health on physical and mental health, as well as a study on supporting women's healths.
