This study assessed university students’ knowledge and precaution practices of Novel Coronavirus (COVID-19) in South Korea, China, and Japan, and investigated their depressive states during the pandemic. This cross-sectional survey collected data from 821 respondents, using an anonymous online questionnaire designed by the Yonsei Global Health Center, from 23 March to 20 April 2020, which included socio-demographic questions, knowledge and perceptions of COVID-19, preventative practices, and the Patient Health Questionnaire-9 (PHQ-9) scale to assess mental health. High proportions of respondents showed good knowledge of the transmission pathways and information related to COVID-19. Contact history as well as concerns about family members and the disease showed statistically significant distinctions by nationality and gender. On the whole, all participants reported good levels of preventative practices. The Chinese group reported the highest preventative practice scores; and females scored higher than males. Moreover, the Japanese group showed the most severe depressive states; overall, females experienced more severe depression than males. Thus, authorities should especially emphasize the importance of COVID-19 precautions to males. Educational departments and health authorities should observe the mental health of university adults during the pandemic and plan interventions to improve it.

Dampness, formaldehyde, and alpha-pinene were significantly related to SBS symptoms in newly built dwellings. We should, therefore, take measures to reduce the chemicals and dampness in dwellings.

The COVID-19 pandemic is novel corona virus infection outbreak that has gone global in 2020. Current prevention policies consist of hand hygiene and social distancing. Emergencies overloaded health services and shocked the logistics chains in many countries, especially Italy and China. Having more than a quarter of its population being elderly, Japan is at high risk for COVID-19 induced morbidity and mortality. This situation cancelled schedules of all routine group exercise activities for the seniors in Japan. While the outbreak is ongoing, staying at home is safe. However, successive days of being house-ridden and limited movement can lead to excessive physical inactivity. Some elderly who are not moving much can lose a significant amount of muscle strength, flexibility and aerobic capacity. It can accelerate the frailty and dependency of the seniors, and subsequently, claiming of care and health services. Moreover, existing and new evidences showed that physical activity can promote antiviral immunity. An alternative to usual group exercise activities is crucial to keep seniors active without affecting social distancing. While staying at home for long, functional exercises maintaining basic level of physical activity and movements are urgently required to be introduced to the seniors in Tokyo and around the world to prevent functional decline. Home exercise is a practical option. Therefore, we made a home-version of the functional training exercise video with different sets of 10minutes exercise for 7 days a week. This breakthrough alternative may sustain health promotion for the elderly persons to preserve their active aging and maintain optimal health.
