After experimenting with a 2m social distance at the Cultural Center in Okinawa, the seating capacity of 400 people was filled with 60 people.I have the impression that there are few. The distance of 2m from each other means that one person is lm to the front, back, left and right. In other words, the area is 2 × 2 = 4㎡. Considering the area up to now is 1㎡, one person will occupy four times the area.The new capacity is 400/4, 100 people. In the experiment, the number was even smaller. Is it because we didn’t consider the human range in our social distance?

The capacity of each train is 140 to 150 people. I feel that there are too many people including standing people. If you take a seat, there will be 40 to 50 people per car. In this case, you only have to think about the left and right sides, so leave two people on the left and right, which is about one-third, or about 15. It will be 1/10 of the capacity. but it will not be news. Is something considered?

The classroom capacity is 40 people. When calculated in front, back, left and right, the capacity is 1/4, which is 10 people. If you want to continue your social distance, you’ll have to quadruple the number of classrooms and teachers, or go to school for a quarter day and the rest in distance. Since it is the latter in reality, ICT utilization must be realized even tomorrow. However, the reason why we are only discussing the September admission system is that we are considering something.

Who decides the social distance? If there is a scientific basis, it will be a small number such as 2.34m. Also, adults and children should be different. However, it is said to be 2m. In the news, it was talked about 2 m in Europe and America, but l m in Japan, or even shorter if you wear a mask. Something is appropriate.

By the way, harassment of non-prefecture number car. I feel a social demistence that is trillion times as large as 2m. Over time, the population is likely to grow to a few per prefecture. People’s hearts are weak, and they easily turn their weaknesses to others. Social distances must also consider human weaknesses. It should never be the reason for the “21st Century Berlin Wall”.
