The purpose of this study is to measure the psychosomatic Symptoms of girls between the ages of 10 and 18 years. For this purpose the questionnaire method was used. The questionnaire used was based on one of about 50 items “concerning neurosis and organ neurosis” developed by Kida, from which basis 70 items were developed and organized into a check list. The subjects of ths study were 755 girls from an urban elementary, middle and high school. The results of this study were compared with the results of two similar studies made last year, one by Kashiwagi of Ochanomizu University in Tokyo and one by Saiki in the city of Nagaoka. The major findings are as follows: 1) When we analyzed the answers to the 70 items of the questionnaire according to the Mann-Test, we found 24_ items in which the frequency increases gradually in accordance with rise in school years. Also, in the individual item scores over a period of two years, these 24 items show increasing frequency. Out of these 24 items, 18 were found to be of increasing frequency according to the results of the test in Nagaoka City as well. From this, though the comparison involved only these two cities, we conclude that these 18 items represent the psychosomatic symptoms of girls in general, without regard to where they live. 2) The correlation between the psychosomatic items scored by the girls in adoleseen and the age at which the menarche was reached is not clearly traced. However, when we tested a small group of about 50 girls selected from those in each school grade who scored extremely high and extremely low scores, we found that the girls with high scores reached the menarche early (accelearted) and that girls with low scores reached the menarche late (retarded), 3) Concerning the correlation between the psychosomatic item scores and the body types, we found a few results. When we divided the subjects into groups according to age (10-13 and 14-18), we found that girls of poor height-and-weight growth (Type M) in the former group tended to mark the lower item scores. As the girls of body type M are retarded some in their whole bodily development, they are also low in the psychosomatic item scores, but this does not mean that they have psychosomatic disorders. While in the latter some tendency appeared.
to Type B. Girls who reached the menarche late, girls who made low psychosomatic item scores, and girls who made low developmental maturity scores tended to belong to Girls of a poor stage of breast development and girls who made low psychosomatic item scores tended to belong to Types H, M and K (those with a poor correlation between height and weight). From these results we may conclude that Type B indicates a generally mature status, while Type E tends to indicate an immature or retarded state in the developmental progress of adolescence. (2) The correlation between the menarche and the stage of breast development was 253 (contingency coefficient), between the menarche and the developmental maturity scores 447, between the breast stage and developmental maturity scores 253, and between the psychosomatic item scores and the developmental maturity scores 417. Each was relatively significant. However, between the menarche and the psychosomatic item scores, and again between the breast stage and the psychosomatic item scores, no significant correlation was found,
By using Mansons' Alcadd-Test which was somewhat modified by author, psychiatric studies were made on the inhabitants, 363 males aged from 15 years old to 85 years in Yasu-machi of Kami-gun, Kochi Prefecture. The results are summerized as follows: (1) The number of patients of chronic alcoholism is 13 and that of alcoholism in anamnesis 13. (2) The validity of Alcadd-Test is assured, especially inThiffrentiation between alcoholic and non-alcoholic. By X2-test the high significance between alcoholic group (A.G.) and control group (C.G.) is proved about the destributiono f marks of Alcadd-Test. Below 19, the marks of Alcadd-Test, alcoholism can not be found. Therefore this test is available also for Japanese. Among 60 items of Alcadd-Test, 30 items are highly significant. (3) So called “Life-Curve of Drinking” is classified into 8 types. A large number of alcoholic is found D1-type, which is characteristic of long-time and heavydrinking.
The physical strength of the Oxford University crew and the crew of three Japanese Universities was examined and the following conclusions were obtained. 1) The Oxford University crew are superior to the crew of the three Japanese Universities in the mean of height, weight, girth of chest, girth of neck, girth of waist, girth of right upper arm, girth of left upper arm, girth of right forearm, girth of left forearm; girth of right thigh, span of arms, breadth of chest, depth of chest, diameter of chest and strength of push. 2) The crew of the three Japanese Universities are superior to the Oxford Uni. versity crew in the mean of trunk flexibility. 3) The mean and the standard deviation of 22 items about the physical strength of English and Japanese crews are calculated. On the bases of the mean and the standard deviation, the standard for evaluation of physical strength which is divided into 5 classes, are made in both cases. 4) In comparison with the difference of physical strength between American and Japanese professional base-ball players or Canadian and Japanese rugby football players, the difference of the physical strength between the crews of English and Japa. nese Universities is less on the whole.
The relation of geographic distribution between death-rate of cerebral hemorrhage and the ABO blood-groups was examined on the observation results in each prefecture in Japan, as a part of the study on the relation of the blood-groups to hypertension. And the same observation was done on the distribution data of cerebral hamorrhage death-rate and blood-groups taken from 11 main countries in the world. The results follow. 1) It is remarkably noticed that the blood type B distributed more frequently in the area where the middle-age death-rate of cerebral hemorrhage was higher, than in the other area. Though the similar relation was found on the blood type O, it was statistically not significant. 2) On the contrary, the distribution of blood type A was clearly higher in the area where the middle-age-death-rate of cerebral hemorrhage was lower. 3) On the relation between middle-age-death-rate of cerebral hemorrhage and blood type AB, any constant tendency was not found. 4) Biochemical racial-index expressed lower value in the area where the middleage-death-rate of cerebral hemorrhage was higher, than in other area. 5) The distribution of gene p, i. e. the gene of blood type A was less, and the distribution of gene q, i. e. the gene of blood type B was more in the area where the middle-age-death-rate was higher. The relation between middle-age-death-rate of cerebral hemorrhage and the distribution of gene r, i. e. the gene of blood type O was similar that of gene q, but the relation was statistically not significant. 6) On 11 main countries in the world, it was noticed that the correlation between the corrected death rate of cerebral hemorrhage and the distribution of blood type A, B and gene q, and biochemical racial index was positivly significant, and blood type O and r showed opposite tendency.
The relation of blood-groups to hypertension was examined on 2, 835 (1, 497 males and 1, 338 females) cases of inhabitants in Fukushima prefecture, consisted of next three groups, that is, the residents in some middle rural districts of the prefecture, the life insurance applicants of a certain life insurance company and the pregnant women visited on Nihonmatsu Health Center of Fukushima prefecture. The results follow: 1) The lower incidence of blood type A, and higher incidence of blood type O and B were noticed apparently by hypertensive and higher blood pressure group, as ompared with opposite groups. 2) By hypotensive and lower blood pressure group, the higher incidence of blood type O and B were found than by the opposite groups. 3) Between the distribution of blood type AB and blood pressure, any distinct trend wrs not recognized.
Correlations between footlength and stature are studied by 382 Japanese adult females in Tiba and Tokyo districts. Footlengths are measured from heel to the top of Ist, 2 nd and 3 rd toes, and called footlength I, II, and III respectively. Results are shown in Tables 1-4 and Fig, 1-5. Our conclusions are as follows. I. On the side difference of footlength. a) The right foot is, on the average, longer than the left by 0.8mm on the footlength I, 0.3mm on the II and III. b) In about 30% of all cases the left is found longer than the right. No side difference is proved in about 30% of cases. c) In about 12% of all cases the II was the longest. No cases was observed in which the III was longest. In about 15% the I and II showed equal length. In over 70% of all cases the longest was the I. The meanvalues of the footlengths are 21.9cm by the I, 21.6 cm by the II and 20.9cm by the III. II. Relation between stature and footlength. a) On the relation between stature and footlength shows a fairly high positive correlation. (correlations coefficient is about 0.7) and regressions coefficients are 0.136 on the I, 0.132 on the II and 0.121 on the III, and σyx are small. b) Correlation between stature and enlarge rate of the footlength (stature/footlength= reciprocal of relative footlength) is very low. c) As regressions coefficients of footlengths (αy) to stature we got 0.136, 0.132 and 0.121 for footlength I, II and HI respectively. And as those of stature t foot lengths (αx) we got 3.592, 3.629 and 3.645. From theoretical point of view, αy and αx are to stand in reciprocal relation and satisfy next expression. αy αx =1 Our results do not satisfy above expression, simply because the subjects of our study are biological materials having much deviations. d) Relation of enlarge rate of footlength stands in a negative correlation, with fairly high coefficient (γ is ca-0.7). This means he who has long feet is not so tall as becoming his feet.
The writer made a biometric investigation, measuring bodies, limbs, heads and faces, for, the 508 inhabitants of Koma district, Hidaka-machi, Saitama-ken, from the constitutional-anthropological point of view. The following conclusion was drawn out of the comparative study of the findings about other districts. 1. Their average height is 160.54cm. This belongs to the “medium” height group in the comparison with other districts, and to the “ short medium ” height group of the Martin!s classification. 2. The cephalic index is 83.08, which belongs to the brachycephalic type. 3. The zygomatic arch width-mandibular angle width irides is 77.83, which belongs to the medium type. It is found through the comparison by the average type index with the inhabitants of other districts that the inhabitants of Koma district have the close affinity to those of Izumo, Koma and Shinshu-Kamiina districts, Hachijojima island and the west coast of middle Korea (with under forth of the average type index), anc the slight affinity to Ainos in Hokkaido, the inhabitants of Ecchu district and southern part of Noto, and Shirakawa villagers (with under twelve of the same index). Thus, it is shown that Koma people belong to the Japanese of Korean extraction, and the old tradition that they are the descendants of the refugees from Heijo (situated at the west coast of middle Korea) is considered to be true.
