As pointed out by H. Toyokawa, there is Food Consumption Structure in daily food-intake in Japanese diet at community level. As well known the food consumption has been markedly changed during 52 years. We report here a trend of changing in the amount of food-intake in sex and age group graphically. As well as, the amount of food -intake of 5 grades of population scale, i.e., town and village, small cities, middle cities, big cities and ordinance-designated cities, were also shown in graphs. In conclusion, a correlation diagram which consists of X axis of the first factor; cereals vs. accompanying dish and Y axis of the second factor; traditional vs. modern diet is shown changed remarkably since 1973. There are difference of modern and traditional diet between resident of ordinance-designated cities and the rural resident in town and village . That is, rural dietary pattern is traditional and the dietary pattern of residents in the biggest cities is modern. Nevertheless, formerly there are apparent differences not only in graphic axis of modern vs. tra ditional but also in axis of cereals vs. accompanying dish between them. However these changes were influenced by the age distribution of the each communities.
In recent years, the objection has recited to carry out physical restraints. Development of tools became pressing need. Side-supports utilize safety catches for users on the beds. The present research was conducted to examine any potential physical influence resulting from differences in adjunctive bed implements. Four healthy women of 21-23 years of age were involved in this study. The subjects were studied for 2 days. Each subject slept on two kinds of beds, and the subject's sleep level was measured using a vigilance level measurement (Bispectral Index = BIS). In this there was a Time Series transformations: difference (1). We compared the sleep data of all 4 subjects for the side rail bed conditions and side support bed conditions. In 3 subjects, there was a difference of the sleep data related to the type of adjunctive implement. We compared data when the bodies of the subjects moved in the period of the sleep. In all 4 subjects, there was difference of the movement data according to the type of adjunctive implement. We concluded that these were due to physiological reactions in the body. The quality of sleep was affected by of the bed conditions.
The mortality rates of pancreas cancer in Japan shows sharply increase as compared with 1950 in both sexes. Pancreas cancer is especially difficult in early detection and the prognosis is less favorable. The cause of pancreas cancer remains almost unknown. It would be necessary to identify the relation between the specific cancer and its high risk group in order to prevent cancer. The purpose of this study was to clarify the high risk region and age group of pancreas cancer death. As data sources, the statistical reports were utilized with regard to the number of deaths by pancreas cancer between the period of 1969 and 1997, and ledgers of national census from 1970 to 1995. The statistics of overall nation were divided into eight regional blocks . The mortality rates of pancreas cancer were calculated by the number of death and population . With regard toregional differences, the trends in the age- and sex- specific mortality rates of pancreas cancer was identified, then regression analysis between year and the age-specific mortality rates of pancreas cancer was conducted, and cohort analyses by every five years birth cohort was made . The mortality rates of pancreas cancer rose in accordance with aging . However, the death rates of 70 years old or older born after the year of 1910 were almost constant . The mortality rates of the same age group in Hokkaido and Tohoku regions were higher than those of other regions. The characteristics of these regions showed high intake of seafood . It was confirmed that the mortality rates of pancreas cancer would increase among males whose age between 40 and 50 years old in metropolitan areas such as Kanto, Tokai, and Kinki region .
