A mass examination of urine (protein and sugar) was made in a farm village Murakami-mura, Sarashina-gun Nagano-Prefecture. (1. The population of the village was 3, 055, including 1, 520 males and 1, 535 females. Those who took the examination were 2, 294, and the rate was as high as 75.1% 73.4% in the male and 76.7% in the female). 2. The rate of discovery of albuminuria was 6.45% in the male and 7.23% in the female. 3. The rate of discovery of glycosuria was 1.25% in the male and 1.52% in the female. Five men and six women were assumed to have diabetes by the reexamination of the urine and measurement of the blood sugar. 4. As for blood pressure, the maximum blood pressure was higher than 140mm Hg. in 119 (31.5%) of 378 examined men above the age of 30, and in 174 (33.9%) of 513. examined women above the same age.
The center of gravity is deeply related to the balance and motion of the body. The change of the center of gravity accompanying physical development an interesting problem to those who study physiology, kinesiology and physical education. Akita, thirty years, ago, measured the center of gravity in Japanese, but his results cannot be applied to Japanese of today. So the authors studied the center of gravity of Japanese in supine position simultaneously with the anthropometric measurements and following results were obtained. 1. Total numbers of subjects were amounted to 2260 including 1-20 ages of both sexes. 2. The height and the relative height of the center of gravity are tabulated as follows. 3. The height of the center of gravity developed with age and its developmental curve showed similiarity with the curves of the stature and the length of lower extremity. 4. The relative height of the center of gravity correlated with the ratio of head grith/hip girth and inversity correlated with the length of lower extremity. 5. Sex difference of the relaiive height of the center of gravity was insignificant from 1 to 17 ages, but significant between 18 and 20 ages. 6. Stature, body weight, head girth, chest girth, vvist girth, hip girth, height of spina ilica anterior, lenght of lower extremity were measured and their developmental curves were discussed. 7. The relative height of lower extremity did not show significant sex difference. 8. Infants and young children had almost same girth in head, chest waist and hip. 9. Hip girth of female was greater than that of male in almost all ages, except adult.
In August of 1959, I have, from the standpoint of constitutional anthropology, made a study of 535 adult males, original inhabitants of the Harima district (Ono, Miki, Yashiro, Takino) of Hyogo Prefecture. The trunk, limbs, head, face, etc., of the living body were measured and a detailed examination made upon 27 items of measuement and index values. The results were then compared with that of other districts. Judging from the fact that the inhabitants of the Harima district reveal various qualities of the highest value in constitutional anthropology, it was admitted that they bear a strong resemblance to the peoples of Yamato, Izumo and Koma, who have originally immigrated from the Asian Continent and who are considered to have brought over the highest form of culture in pre-historic Japan. It is an interesting fact that the inhabitants of Harima district who lived within the sphere of influence of the Yamato dynasty, should resemble the the people of Yamato, more than the inhabitants of Bicchu, Inaba, and Izumo, which are geograpeically more, closely related to Yamato.
Since 1947 to June 1954 we have taken measures six times on 11 points of physical strength such as the height, the weight & the girth of the chest, etc. and athletic' function such as the grip, back muscles etc. on 52 novices or new in 1947, while 31 of them have retired from the dohyo, and 21 are left. At the beginning because of training the weight had decreased, but after 2 years and half it began to increase. After 3 years and a half, on account of training of the body, especially the upper part of the body, grew round. The girth of the chest, waist, , , upper arm and under arm and width of the shoulder, chest and hip had grown well, .. when 3 years and a half passed, the growth was evident, eg. sumo physical proportion.. On the growth of the chest, increment of the transverse diameter was more than. that of the anteroposterior diameter which shows the similar tendency on the growth of the judo-men as reported by Mr. Shioya. In a comparison with ordinary people, the grip is stronger than back muscles and in spite of the growh of the body, athletic function has not grown so much because of injury by hard training. Generally speaking, among those who retired within a year many had been squat at the begining, short in height, and heavy in weight, and did not increase in height.. Among those who retired within two years and a half, many had increase in height to a certain degree but the expected increment in weight was not satisfactory. A comparison of active and retired sumos, most of the former showed graduaL, increment in weight and most of the latter lost weight and required consideradle amount of time to recover. The formor excelled the latter in height and weight from the beginning. To be a good sumo requires training and a mind which is able to endure thetraining, as well as inherent physical strength. During the pennant seasons of 1948, 1949, and 1950 absorption of food of the junior grade of wrestlers without regards to the seasons were 3500-4000ca1.
The writer made a biometric investigation from the constitutional-anthropological -point of view, measuring bodies, limbs, heads and faces, for 537 adult inhabitants of the district around Lake Tazawa, Akita Prefecture, in January, 1958. The followings -are the brief summary of the findings obtained through the detailed examination of measures and indices, covering 25 items, and the comparative analysis with those of the inhabitants of other districts. 1. The average height of the inhabitants here is 161.187L-0.25cm, which belongs to - the “short” height group of the Martin's classification and it ranks about in the medium in comparison with other districts. 2. The cephalic index is 82.92 0.61, which is close to the brachycephalic type of the Martin's classification. 3. The zygomatic arch width-mandibular angle width index is 80.74 0.17, which shows rather “wide” face type. The synthetical comparison shows that they had the closer affinity to the inhabitants of Aira and Takachiho than those of Ou district, though the locality is in Ou district. Those results suggest that they had communication with the Continent from the ancient time.
The followings are the brief summary of tne findings obtained through the survey of real state and changes of cultivation and the examination of the factors that effect pon development at the Konsen field. So far, farming was the main method ofu the operation in cultivation there, but recently it is changing to the mixed operation of farming and dairy-farming. The mixed operation, however, is not easy work not only for the new settlers but also for the old settlers, and pretty many of the settlers left the field. It is considered that poverty and giving up of farming at the area are due to the fact that they set importance on clearance and farming. As that is the case, the writer -developed the study examining which factor is qualitatively most dominant over cultivation. For that, the writer took up the average area of the cultivated field, which is usually used for the same purpose, for the standard of the rate of progress of cultivation. The factors which effect upon cvltivation were chosen from the results obtained by the writer's colleagues. As the result it was found that the necessary factors for cultivation of this field are introduction of the modernized agricultural method, the appropriate guidance and fostering of it and preparation for receiving it. Even if it becomes successful after the trial to fulfill those necessary factors, there is a limit in cultivation by the way of setting emphasis on farming. The setters should find the way out in dairyfarming, and it is needed to take the proper action to enable them change their work to stock raising.
