    Perinatal mortality rates and proportion of deliveries by birth weight, maternal age, birth order, single or multiple birth, sex, place of delivery, and delivery attendant, were compared between Gifu Prefecture, and Japan as a whole in 1974. The results were as follows: 1. The perinatal mortality rates in Gifu Prefecture were higher than those of Japan as a whole. 2. The difference between perinatal mortality in Gifu Prefecture, and those in Japan, was related to the proportion of low, birth-weight deliveries.

    The fishing activity with self-contained underwater breathing apparatus (shortly SAC U B A) diving method and the fishermen's health condition were investigated. Data were obtained by field survey on diving fishermen on two fishing communities in Okinawa in June and July, 1979. Another data were based upon the clinical records of decompression sickness, usually called divers' disease, patients who attended the Hospital, College of Health Sciences, University of the Ryukyus for the hyperbaric therapy from July, 1973up to August, 1979. Results are summarized as follows:(1) Divers' disease patients have increased rapidly among SCUBA diving fishermen in these few years.(2) As to the cases of the patients, the "Bends"-typed sickness, the comparatively slight one, occupies the highest ratio (59.6%).(3) The failure in the "decompression" method for the therapy, which has been almost done among the diving fishermen, makes sometimes them more serious sickness.(4) SCUBA diving fishermen force themselves considerably to be engaged in the diving activity as compared with the standard diving method not to be suffered from the divers' disease.(5) Their forcible diving activity is connected with their competition for a good catch, which seems to be leading to the exhaustion of marine resources.(6) The frequent occurrence of the diving fishermen's decompression sickness is closely related to the cultural factor of traditional fishing method, ecological factor of marine resources, and social factor of social structure such as co-operative systems of Okinawan fishermen.

    Effects of out-migration upon households composition are not necessarily fixed. According to variation of demographic characteristics of out-migrants, households com-position may change in different ways. This paper aims to enumerate the size of out-migration and clarify the change of households composition, using the residents-registry on Sakushima (Mikawa-Bay, Aichi-Prefecture) from 1955 to 1977. Here the out-migration are classified into 4 types as follows:(A) Migrants move alone and he or she is a part of members of his or her household on Salcushima.(B) Migrants move alone and he or she is a sole member of the household on Sakushima (at the time of out-migration, he or she lives alone).(C) Migrants move together with other members of his or her household and they are a part of members of their household on Sakushima.(D) Migrants move together with other members of his or her household and they themselves consist of the household. The type of out-migration by age is as follows:(1) Out-migrants of age 0-14 mainly belong to type (C) and (D).(2) Out-migrants of age 15.29 account for over 70% of all out-migrants and over 90% of them belong to type (A).(3) Out-migrants of age 30.44 belong to type (C) and (D).(4) Outrmigrants of age 45-59 belong mainly to type (C) and (D), even though type (B) accounts for over 30%.(5) Almost 70% of out-migrants of age 60 and over belong to type (B). The main streams of households composition change are due to following threeways:(1) A couple and their child(ren) → A couple only(2) Parent and his or her child(ren) → One-person household(3) A couple - One person household In spite of the main stream toward one-person household in the observation periods, the number of one-person households has not increased since 1970. It has been resulted from the increase of out-migration of type (B). This change of households composition side-by-side with the aging of population after a continuous out-migration of younger ages may create an another phase of out-migration.

     男は女よりも多く生れる.にもかかわらず男は女よりも多く死ぬ.このような死亡の性差の原因は男女間の生理的・解剖的な差異によるよりも,むしろ環境諸要因による後天的影響によるところが大きいとされている. 著者らは,このような点を明らかにすべく1975年における我が国の主要死因別死亡率を用い,特に郡部と市部の死亡率および死亡性比について比較し,考察した. 分析の結果,死亡率については郡部と市部の間に格別顕著な差はみられなかった.明らかに解剖的・生理的な差異があるものを除くと,男が女に比べ郡部,市部ともに著しく高い死亡率を示すのは,結核,食道癌,肝臓癌,呼吸器系癌,胃潰瘍,肝硬変,交通事故などであった. このような結果から,死亡性差の原因は都市化と関連する環境諸要因というよりも,むしろ喫煙や飲酒習慣,医療行動など個人に帰属する諸要因によるところが少なくないことが示唆された.
