Air Circulation Confinement Experiments in the CEEF - Changes in Physical Conditions and Health Managements of Eco-nauts

In FY2005, the first series of seven-day closed habitation experiments was conducted using the Closed Ecology Experiment Facilities (CEEF). The operation period of CEEF is planned to be extended to four months by FY2009. The CEEF is a two-manned system. The habitants, called “Eco-nauts”, are responsible for operating the system as a part of an artificial environment. Therefore, their continuous health checks are very important to the success of the habitation experiments. To check their health condition, medical examinations were carried out before, right after and two months after the series of experiments. During each experiment, physical data were obtained and evaluated by medical doctors using a web-video-meeting system. The primary objective of this study was to verify if the schedule and examinations selected for the health check of the Eco-nauts were successfully carried out. The secondary objective was to monitor the data of the Eco-nauts and confirm they were kept in good health. These two objectives were fulfilled.
