Abstract (in Japanese) (See Japanese page) 
(in English) We present a method to detect a sudden physical disorder in private rooms such as restrooms. In this paper, firstly we specify the required functions for this method, which are High Availability, and Quick Responsiveness. Secondly, we propose the approach to fulfill the requirements using following key words: Bayesian Network, Approximate Inference. In this way we have succeeded in detecting physical disorders such as faint or convulsion in a fixed condition for 100% within 60 seconds. However the accuracy decreases to 77.5% when try to detect all the physical disorders, the result definitize the problem of the implementation.
