Here, we report such results of studies about factories, elementary schools, junior high schools, and senior high schools as follows; 1. On factories, modes of concentration curves are between 5 and 15 min. before beginning time of the work, and ratio of concentration in 5 mine. is about 25%. 2. On elementary schools and junior high schools, modes of concentration curves are between 0 and 15 min. before beginning time of the lesson, and ratio of concentration in 5 min. is about 23%. 3. On senior high schools, modes of concentration curves are between 0 and 10 min. before beginning time of the lesson, and ratio of concentration in 5 min. is about 30%.
