Abstract
In Japan, the number of labor accident in the construction industry shows still high value as ever. According to the statistics of last year, the number of labor death accident in the construction site shows about 400, and this number holds one third of the number of labor death accident in all industry. It was also made clear by the statistics that this number is the most in all industry. It is the present situation that time and cost for the safety education in the construction site is decreasing as the result of severe price competition. In spite of having taken a lecture on safety education, many problems of causing the accident which was originally able to be prevented have also been reported because of the too self-consciousness. In this research, we paid our attention between the concentration to the job and the pulse of the worker, and we developed the reminder system to the unsafe behaviors by using the sensing data of worker's pulse.
