Abstract
We are planning to develop the work evaluation system using our thermal physiological and psychological prediction model. This paper describes the results of measurement of physiological and psychological data that were measured in experiments simulated landing in winter surface water and standing position work on the coast, and a comparison of experimental and calculated result of body temperature about in surface water. The calculated results agree well with the experimental results. In addition, the calculated results supposing the accident of landing in actual winter surface water are described.
