The time trend analysis of fertility from 1950 to 1979 in China was carried out by employing two-phase regression lines. The nation-wide fertility sampling survey in 1982 provided the data of Total Fertility Rates and Age-specific Fertility Rates, which formed the basis for the present analysis. A certain body of literatures proposed a persuading stage classification for a series of population policies administered in the People's Republic of China since 1949. The present fertility analysis was linked with the proposed stages as shown below. 1) 1949-1956 the period of non-particular population policy 2) 1956-1958 the period of the first provision of birth control policy 3) 1958-1962 the period of the Great Leap Forward Campaign 4) 1962-1966 the period of the second provision of birth control policy 5) 1966-1969 the period of the Cultural Revolution 6) 1969-1979 the period of the third provision of birth control policy 7) 1979-the period of the fourth provision of birth control policy Comparing the three population policies administered by the year of 1979 in connection with the fertility, we recognized the periods during which birth control policies were administered synchronized the changing trend of fertility. The time-event relationship was most remarkable in the third provision of birth control policy. However, in the first and second provision of birth control policy, the mentioned relationship was obscure.
A study of the geographical distribution for the place at which habu bite occurred were carried out in order to clarify the geographical features possibly relating to the occurrence of habu bite on the Tokunoshima Island. The following results were obtained; 1) The distribution for the frequency of habu bite per grid-square of 1 km2 conformed to the negative binomial distribution rather than to the poisson series, suggesting that the places at which habu bite frequently occur tend to cluster. That is, the habu bite in Tokunoshima town were found to occur frequently in the densely populated and/or well-cultivated areas. 2) The incidence rates of outdoor habu bite per unit of population differed greatly among the grid-square groups classified by cultivated land with high incidence in well cultivated groups, while the rates for indoor habu bite did not differ so widely among the groups. 3) The incidence rates of habu bite per unit of cultivated land differed widely among the grid-square groups classified by population size for both indoor and outdoor bites, being high in densely populated groups. 4) The habu-snake was frequently caught in the well-cultivated area being close to the place of residence. The fact indicated that the habitat of the habu-snake might be nearly close to the farmland. From the above, it was suggested that the occurrence of habu bite during outdoor activity might be attributed to the cultivated land habitable for habu-snake, while the place of residence in or very close to the cultivated land might be responsible for the occurrence of indoor habu bite.
In the first report of this series the author has described the relationships between the numbers and the weight of garments and the complaints on warmth of daily wears and working clothes in June of Akita area. This report deals with those relationships above mentioned in four seasons in the same area. The results are as follows: 1. As for the subjective complaints, fewer people judged as comfortable in all the senses of warmth, humidness and comfortness about the outdoor garments than those of indoor clothings. 2. Coolness of body parts were complained in the order of feet, hands and faces. However, these complaints decreased as the temperature increased. 3. In the cold season of February, characteristic feature was seen in wearing the same kind of clothes one over another in those of underwears, underpants and socks. 4. As for the relationship between the temperature and the feeling of warmth, people who responded as?gcool?hin wearing outdoor working clothes, they seemed to be tend to feel cool than others judged from the regression line. On the other hand, they wear less clothes indoor in every categories of senses compared to those of outdoor. And they seemed to wear thinly in accordance to temperature increase judged by steeper inclination of the regression line.
In order to establish the Japanese standard distribution in thickness of subcutaneous adiposal tissue layer, the authors are studying successively the thickness in all generation and at many regions by A-Mode Type Ultrasonic Device which has been developed recently. In this report, subcutaneous fat thickness in 5 locations, i.e., biceps, triceps, subscapula, suprailiac and thigh anterior in 1471 infants aged 3-6 years in cites of Musashino, Naha and Asahikawa, as the first step of serial study for all generation. 1)The original data assessed are shown in both of table and histograms. 2)Subcutaneous fat thickness is larger in girl than in boy throughout infant generation. 3)There are not any correlation between height and subcutaneous fat thickness in respective location of body, nevertheless there are apparent positive correlation between subcutaneous fat thickness and both of weight and Kaup's index. Kaup?fs index get lager correlation coefficient than weight between subcutaneous fat thickness.
