Condition of autonomic nervous function and their living background among Mongol children in China. As in Japan, to solve the health problems of children is the important subject in China. In particular, increase of obesity, poor visual acuity and decreasing of blood pressure control function has been pointed out. Therefore, the purpose of this study was to make clear the condition of autonomic nervous function and their living background among Mongol children in China. The subjects were 245 children (119 males and 126 females) from 5th and 6th graders who enrolled in Mongolian elementary schools located in urban areas and pastoral districts in the Inner Mongolia Autonomous Region, China. The survey was conducted in May 2017. The data of the autonomic nervous function, physical characteristics and living condition were collected in this research. The cold pressor test (CPT) was using for the measurement of autonomic nervous system. The main findings obtained as the results of this research were as follows. Although there was no regional difference in the physical characteristics of subjects, bedtime and wake-up time of urban children were later than pastoral district children and screen time of pastoral district children was longer than urban children. Moreover, the vasopressor response of urban children was larger than pastoral district children. Therefore, considering the regional differences, analysis of the relationship between vasopressor response and living background confirmed that physical activity after school had positive effect on autonomic nervous function.

  The main subject was aimed at raising interest for the typhoon of the infant through the cooperative activities of the expression or the video watching, and showing the practice model that learned a natural menace and means to protect the body through simulated experience , and submitting the positioning by childcare contents. After three times of childcare practice for 5 years old child, the action that an infant was interested in a typhoon was seen, and an example to feel the sprouting of the life respect was seen, and there was conversation about the typhoon at home of 81.8%. As a future problem, I raised the improvement of education effect by the cooperation with the home, and the contrivance of the practice model according to the development, and the construction of the education of emergency procedures that classified the natural disaster whole into the field of vision.

  In this study, we examined a difference of physical activity in free play (in the nursery school and in the park). Furthermore, we examined a characteristic of fundamental movement to by the free play in a nursery school and the park. A total of 14 children (5 boys, 9 girls) participated.

  Physical activity during free play was evaluated with accelerometer (Lifecorder). We used the observation method for the measurement of the fundamental movement during free play.

  We found the following:

  1) By the free play in the nursery school and the park, the physical activity of the girl had a difference (nursery school: 1,191 steps, park: 2,361 steps).

  2) A kind of fundamental movement had a no difference, but, in the free play in the nursery school and the park, a difference was seen in the frequency according to the exercise category.

  3) In the “inactive” girls, a positive effect was seen in physical activity and fundamental movement by the free play in the park in comparison with the free play in the nursery school.

  These results suggest that for “inactive” children, in different environment may improve physical activity level.
