A device for underwater weighing by utilizing a swimming pool was tentatively made, and with it, the weights in water of 111 male students were measured. And from the thus obtained weights in water, the body density was calculated to be compared, for its justification, with those already reported by other workers in the literature. This study aimed at the examination of the body composition of boys in the developing stage. And the points to pay attention in this case were discussed. The principal findings were as follows: 1) The body density obtained by this method from the above mentioned subjects was 1.0724 ± 0.0092 (mean ± standard deviation). This approximately agrees with 1.07, the normal (general) value for the Japanese adolescent males, estimated from the reports in the literature. 2) The residual volume (RV), an important factor determining the body density needs to be measured exactly. The maximal expiratory level which affects RV, is relatively easy to determine in case of the underwater weighing thanks to water pressure. When elementary school children are the subjects of weighing, however, sufficient attention must be paid to avoid danger, because breething needs to be arrested during a time from the attainment of the maximal expiratory level until the end of the weighing. 3) The underwater weighing can be made within 5 seconds after the attainment of the maximal expiratory level of the subject. The body weights in water of the subjects of the present study averaged 3.03±0.578kg (range, 4.25 to 1.60kg.).

The relationships between the eruption order of the first permanent teeth on children in a kindergarten, way of feeding at infancy, and taste at the present time were examined. The aim of this study was to investigate the effects of their daily consuming foods including at their infancy on the changes in the eruption order of the first permanent teeth from the first permanent molar (M1) to the central permanent incisor (I1). One hundred and fourty-nine children (82 boys and 67 girls) whose first permanent tooth was mandibular I1 (I-type children) were compared with 111 children (48 boys and 63 girls) whose first permanent tooth was mandibular M1(M-type children) on their ways of feeding at infancy and their taste at the present time. Results were as follows: 1) In both sexes, the evident relationship was observed between the eruption order of the first permanent teeth and the ways of feeding in infancy. M-type children were breast fed for longer time than I-type children. In the discriminant analysis, breast feeding was related to the M-type eruption, and bottle feeding was related to the I-type eruption. 2) Weaning was started earlier in M-type children than in I-type children. The rate of the children who began weaning earlier than 4-months old was significantly higher in M-type children than in I-type children. 3) The M-type children liked fruits and fish more than I-type children. 4) These results suggest that elevated sucking and chewing frequency by breast feeding and early start of weaning at infancy influenced the eruption order of the first permanent teeth as well as the growth of the mandible.

Previously, I have discussed the changes within the life cycle, or turning-points in life and their interrelationships and changes from the Tenpo era to the present. In another paper, the attention is focussed on the last phase of the life cycle, specifically upon the custom of abandonment of the elderly as reflected in various traditions and works of classical literature. Numerous sources exist, however reliable sources are limited ; thus the studies were limited from the Tenpo era to the present. During the research, I discovered the massive work "on Retirement" by Professor Muneshige Hozumi of the Faculty of Law, University of Tokyo which examines numerous works of ancient Western, Chinese and Japanese literature. This work is the result of diligent effort and examines the handling of the elderly from a legal viewpoint. According to Professor Hozumi, Indian Holy Scriptures state, "Human life is divided into a student period, a "head of the family" period and a retirement period". This classification agrees with my model of the life cycle in some respects. The first edition of this book was published 95 years ago and already belongs to the historical literature. In order to provide a reference for the continued study of the senescence period of the life cycle, I have confirmed portions of the references cited in Professor Hozumi book at the National Diet Library, University of Tokyo General Library, University of Tokyo Faculty of Economics Library and Faculty of Culture Library. Using the materials obtained from this book as a foundation (references at the end), an overall treatise on the handling of the elderly was written using the custom of cannibalism which probably originated from victimization of the elderly as well as the custom of abandoning of the elderly with final supplement by my own opinion. The range of studies on the life cycle is extensive beyond the limit of any one science. What I have unearthed is only a shallow outline. Discovery of a basal structure of cultural and social life persisting through a long time span may be a contribution to the study of human ecology.

To clarify Japanese university students' attitude toward suicide and to relate it with their views on life and death, a questionnaire survey was conducted for 1, 366 students of University of the Ryukyus in Okinawa Prefecture in 1992 The major findings were as follows.1. The subjects who had thought about suicide (called "suicide awareness" group) accounted for 6.3% ; compared between the students from Okinawa and those from other prefectures this rate was significantly higher in the latter (p<0.01).2. The suicide awareness group thought about death earlier in their lives and had more positive attitude toward death such as "release from suffering, " "beautiful" and "peaceful" than other two groups.3. The association between attitude toward suicide and consciousness about death in the homeland was recognized by the suicide awareness group (a half of the students) more than by other two groups (p<0.001) and the suicide awareness group showed higher proportions in justification of suicide (p<0.001) and in courageous behavior for suicide (p<0.05).4. Compared with other two groups, the suicide awareness group had a higher proportion in positive feeling on the effect of religion on death (p<0.001) and a lower proportion in belief of metempsychosis (remigration of souls) (p<0.001).5. Regarding the association with terminal situation, the suicide awareness group showed a higher proportion in recognition of cerebral death as human death (p<0.001) and differed from other two groups in desired place at death and desired treatment in the terminal period.

Analyzing the records kept in Koza Public Health Center, this study aimed to elucidate tuberculosis (TB) control in Okinwa after World War II. The records included each patient's registration year, name, sex, date of birth, address, occupation, disease classification, treatment classification, bacterial tests, type of chemotherapy, surgical history, length of chemotherapy and ambulatory treatment. Pulmonary TB cases, 5, 289 in total, were the subjects of the present analyses . Based on the date of registration, the patients were assigned to phase I(1952-1961) or phase II (1962-1971), since the treatments changed from the concomitant use of 2 medications (isoniazid and pyrazinamide) in the former to that of 3 medications (streptomycin in addition to the above 2) in the latter . From the viewpoint of public health, medical care for TB patients was markedly improved from phase I to phase II, as exemplified by the decrease in the mean medication period from 3.9 years to 3.1 years and the decrease in the mean control period from 4 .8 years to 4J years. It is concluded that the home therapy system which was introduced to TB contorl in Okinawa in the postwar period to cope with insufficient medical resources, particularly in health centers, functioned effectively.

The purpose of this study is re-evaluation of population dynamics, especially of marriage, divorce, and birth and stillbirth by legitimacy, in Japan before the first population Census. Formerly we reported results of similar analysis for the period between 1872 and 1898. In this study, we have investigated the successive period from 1899 to 1919 which is the preceding year of the first Census. The marriage rates over this period were estimated to be around 50 to 60 per 1, 000 unmarried women over age 15. These figures are very low in comparison with those of the period after 1920. The official statistics of population before 1920 was based on "the Koseki (family registration system)" in contrary to the census after 1920. This difference may contribute the lower marriage rates for the period of this study. The divorce rates were estimated to be 6.0 to 8.4 per 1, 000 married women and showed a clear decrease since 1899. The illegitimate birth was found to be very frequent in the study period. It was estimated that one out of fifty unmarried women beared one child per annum. But the ratio of illegitimate births to all birth had showed a decline since 1912. The sex ratio of illegitimate birth was found to be lower than that of legitimate birth. The illegitimate stillbirth rates were around two and a half times higher than those of the legimate. It is considered that the enactment of the Civil Law in 1898 had contributable influence on these trends of marriage, divorce and the legitimacy of child.

We studied 388 cases who have consulted by telephone twice or more, and were selected from records kept at the Gunma Prefectural Mental Health Center since its opening (1986) until March 1993. For many cases, such series of consultations ended after no more than four calls, but 19 cases have lasted over several years or over a hundred calls. The most frequent type was related to mental illness of various sourts; the second most frequent concerned problems of children. Among the first type, many cases had visited psychiatric hospitals or clinics, increasing percentage wise as they passed the stages of their condition; first, anxiety overhaving fallen mentally ill; second, dissatisfaction or doubt about psychiatric treatment; third, anxiety over rehabilitation. Many cases felt completely at a loss over difficulties in finding solutions to their problems even after consulting with mental hospitals, clinics, or other counseling facilities. Cases continually used telephone for a sense of ease and/or familiarity with counselors of the Center. It was suggested that these continuing telephone consultations followed public relations that the Center's services were available without charge, and especially that they were so easily accessible by telephone.

Female pelvis, as the most important part of maternity, has repeatedly studied not only in Japan but in foreign countries, but few with the research from the point of view of relative growth throughout thewhole ages till maturity. This study of 1543 normal pelvis, sampled at random by sex, year-age (month-age in infancy), through the ages between 1 month and 17 years, was attempted to clarify the developmental changes of pelvic cavity by means of stochastical analysis on the radiographic measurements.The results obtained are as follows.(1) The pelvic cavity was found to become larger with the age advanced, and to show a particularly rapid. growth for three months after birth, between the ages of 1 and 4 years, and also in the puberty.(2) Sexual differences of pelvic cavity were observed already in the infancy, that is, the upper structure in males and the lower structure in females were greater than those in opposite sex. After 10 years old, the growth of pelvic cavity in females was remarkable and in the puberty every parts of the cavity measured in females was greater than that in males.(3) The investigation on relative growth between each parts of the pelvic cavity measuied in this study revealed that in the early infancy the maximum distance between both obturator-foramina increased most rapidly while the distance of Wollenberg's Y-cartilage-line did eminently in the later infancy and also in the puberty. The growth of breadth of the cavity was superior to that of the height in the infancy, while after that the latter became superior to the former ; in the puberty the both were almost of the same increase from the point of view of relative growth.(4) The growth of the pelvic cavity had so close relationship to that of the pelvis that the coefficients of correlation between them gave very high possitive values.

The purpose of this research is to compare two different high altitudes Tibetan group’s physiques, physical strengths and physiological functions.In total 199 Tibetan subjects, 101 subjects (48 males and 53 females) from a 1800 meter highlands (mid-altitude group) and 98 subjects (48 males and 50 females) from a 4000 meter highlands (high altitude group) were examined morphological and physiological characteristics such as height, weight, vital capacity, blood pressure, grip strength and two step exercise test. Subjects for the analyses were extracted from the total subjects by matching the age and sex between the two groups, 53 subjects respectively.Compared to the mid-altitude group, the high altitude group had a smaller body size, lower physical abilities except for endurance performance, lower systolic and diastolic blood pressure and lower vital capacity. The results of vital capacity were different from that of previous researches. Although the blood pressure was remarkably low in high altitude group, it is difficult to attribute the cause only to the difference of altitude, because besides the altitude some differences such as occupations and eating habits existed between the comparison groups.

The main purpose of this study was laid on vital statistics concerning basic factors of births, deaths, marriages, and divorces including changes in population growth of the Korean population in Japan. An analysis, one of series of demographic-ecological studies on Vital Statistics from 1965 to 1975 issued by the Ministry of Health and Welfare of Japan was undertaken in order to study the recent trends of the Korean population in Japan and compare it with the Japanese population. The major findings are summarized as follows. 1) The Korean population in Japan has been slightly increasing yearly, and the average annual growth rate was 1.05 percent per year from 1965 to 1975.The ratio of total dependent population has decreased from 57.1 percent in 1965 to 50.8 percent in 1975, but it is expected to show a little increase in the near future. 2) Trends in crude birth rate and crude death rate from 1965 to 1975 have steadily declined, while natural increase rate was higher than that of Japanese.The crude birth rate and crude death rate of the Korean population in Japan in 1965 were 21.7 and 5.7 per 1, 000 population, in 1975, 17.9 and 4.7 per 1, 000 population, respectively, whereas the corrected death rate was rather higher than the Japanese. More interestingly, it is concluded that the Japanese folk superstition of Hinoe-Uma in 1966 seemed to be a factor influencing the crude birth rate, stillbirth rate of Koreans in Japan, whereas the extraordinary passing phenomenon was not showed in Korea. 3) The infant death rate has declined very rapidly from 15.8 in 1965 to 8.2 per 1, 000 live births in 1975 and stillbirth rate was also declined from 56.3 in 1965 to 40.5 per 1, 000 total births in 1975. 4) Major cause of death have remarkably changed due to the efficient public health services. Malignant neoplasms, cerebrovascular disease, heart disease were for the three leading causes of death of the Korean population in Japan in 1975. Specific death rates by major causes of death of Koreans in Japan for liver cirrhosis, accidents, suicide, and pan-tuberculosis were higher 38.0, 38.5, 22.4, and 12.8 per 100, 000 population in 1975 than that of the Japanese, respectively. 5) Marriages of Koreans in Japan have increased and the crude marriage rate was 9.8 in .1965 and 11.2 per 1, 000 population in 1975, slightly higher than that of Japanese . It is more considered that the intermarriages of the Korean-Japanese bridegroom or bride have increased and it will overwhelm the level of Korean-Korean marriages in a few years, and general divorce rates have tended to increase following the Japanese.

Life expectancy of woman at birth usually exceeds that of man in developed countries. The purpose of this study is to explain the reason of such sex differential in life expectancy at birth in Japan in recent years, analyzing sex differentials of age-specific death rates and mortality rates by causes of death. The calculated life table and vital statistics in 1990 were employed for the analysis. The analysis of age-specific death rate showed that the sex differential of mortality in age 50 and over explained around 70% of the sex differential in life expectancy at birth. In contrast, the sex differential of mortality rate in age 0 explained only 1 % of the difference. From the analysis of mortality rate by causes of death, it was shown that sex differentials of mortality from malignant neoplasm, heart diseases, cerebrovascular diseases, pneumonia and bronchitis, suicide, and accidents mainly contributed to the recent sex differential of life expectancy at birth. Of these causes, malignant neoplasm was the leading contributor to the sex differential in life expectancy at birth. From these results, it is considered that elongation of male life expectancy at birth would be possible by improving the life-style.

We have tried to classify the health/medical services administration in Okinawa after World War II into five periods and to describe the trends of major communicable diseases and causes of death for each period. First period (1945-49, the period under the administration of the U.S. Military Government (USMG)): In those days, the major activities of health/medical services for Okinawa Civilians were first, supplying food and second, controlling acute communicable diseases; especially, malaria which was very prevalent. USMG executed an aggressive sanitation program which included DDT spraying. Second period (1950-51, the period during which the USMG administration turned control over to a civil administration): Acute communicable diseases were eradicated by the aggressive sanitation control, but chronic communicable diseases - leprosy, tuberculosis, venereal disease and others became more prevalent. USMG issued many ordinances to affect "control of communicable diseases". USMG especially showed deep concern for controlling venereal disease and established district health centers and began free treatment for venereal disease in these centers. Third period (1952-64, the period of full-scale construction of U.S. Military bases): Markets, crowded houses, slums, so-called red-light districts and other similarly difficult living situations developed around U.S. Military bases with the full-scale construction of the bases, and chronic communicable diseases, especially, tuberculosis were very prevalent in the 1950's and 1960's. However in the 1960's the death rate due to tuberculosis decreased gradually as did the rates for gastroenteritis and pneumonia or bronchitis. On the other hand, the death rate due to adult diseases such as cerebrovascular disease, cancer, heart disease and others increased year by year. Fourth period (1965-71, the period of a great increase in financial and technological aid from the Government of Japan to Okinawa): The period started from the time when the late Prime Minister Mr. Sato made a speech on his visit to Okinawa in 1965 that a medical school should be established in University of the Ryukyus. From that time the financial and technological aid from the Government of Japan to Okinawa was substantial. A vaccination program to fight tuberculosis for health personnel, families of tuberculosis patients, students of the first and second year of junior high school was established in 1966, and consequently the morbidity rate due to tuberculosis decreased year after year. Fifth period (1972-, the period after Japanese laws were applied). After the application of Japanese laws, the condition of health/medical services in Okinawa improved considerably. The mortality and morbidity rates due to adult diseases increased significantly as the rates for communicable diseases declined.

The Japan Poison Information Center (JPIC) received 205, 199 inquiries from citizens and medical personnel for 5 years from April, 1989 to March, 1995. And, the number of inquiries concerning with suicide in those was 5, 778. In July 1993, the book named the Suicidal Manual were published in Japan and since then, the inquiries concerning with suicide attempts have increased. So, I analyzed these data about implicated products and contrasted the data received before the publication of the manual to the data received after that on purpose to make clear the affection of the Suicidal Manual. In regard to the substance that was selected in suicide attempts cases, teen-ager and the twenties tend to use medicines, especially over-the-counter drugs and older people tend to use agricultural chemicals. After the book was published, the number of inquiries about some over-the-counter drugs that were shown as appropriate way for easy and painless death in the book had increased. So, it is very important to give the young people the information of drug toxicity and appropriate management of drugs to decrease the influence of the book.

The twinning rates in 46 Prefectures of Japan were calculated from the vital statistic data in the period 1955.1959. The zygosity of twins was estimated by the Weinberg's differential method. The twinning rates increased from a low level in the southwest of Japan to a high level in the northeast. The tendency was more definite in the dizygotic twinning rate than in the monozygotic one. In old times of Japan, there had been a superstition of abhorring twin births . To investigate whether the tradition has been transmitted down to the postwar time or not, correlation-coefficients between the twinning rates of 46 Prefectures and their parameters which might affect the registration of twin births were figured out . The mediate parameters were the decreasing magnitude of the crude birth rate in the year of "Hinoe-Uma", the proportion of the delayed registrations of live births to total ones, the percent of the unlike-sexed-to total twins, and the proportion of the stillbirth-to live-birth twins . No result supported the fact that the superstition has affected the registration of twin births in the postwar era of Japan. Relationship between the twinning rate and the maternal age at birth was also analyzed during 19601967 in Japan. Although the monozygotic twinning rate seemed to have no relation, the dizygotic one showed a high maternal age dependence. The tendency was analogous to those reported in other ethnic groups. The author express his appreciation to Dr. G. Watanabe for his advice .
