Total body fat mass was estimated in a group of 65 healthy male and 39 healthy female Japanese aged 40-77 using the D₂O dilution method, and by measurement of skinfold thickness at 14 sites. The weights of skin, and subcutaneous and internal adipose tissue were calculated. The women had a higher total adipose tissue weight than the men (p<0.01). Absolute subcutaneous adipose tissue weight in women was about double that in men. However, absolute internal adipose tissue weight and internal adipose tissue weight as a percentage of body weight showed no significant sex difference. The relationship of total and subcutaneous adipose tissue weight with age showed a correlation of r=-0.283 (p<0.05) and r=-0.367 (p<0.01), respectively, for men and r=-0.329 (p< 0.05) and r=-0.428 (p<0.01), respectively, for women. The correlation of internal adipose tissue weight with age was not significant, but the internal adipose tissue weight/total adipose tissue weight ratio increased steadily with age in both sexes.

Mesiodistal and buccolingual tooth crown diameters were measured on the dental casts collected from four different populations in Japan and one from Taiwan, China. The samples consisted of 206 senior high school students in Akita, 190Tanegashima, 122 Tsushima, 225 Okinawa and 197 Taiwan. Measurements were made twice by one operator using specially made sliding calipers. The reliability of measurement was evaluated on each tooth.
From principal component analysis for summarizing variations of the measurements and their indices, seven components were extracted. MAHALANOBIS' generalized distances among five populations were calculated based on eight tooth crown diameters from the above components. The five populations were divided into three groups: one was solely Tsushima, and the other two were Akita and Okinawa, and Tanegashima and Taiwan. When compared with prehistoric Japanese, Jomon and Doigahama-Yayoi(BRACE and NAGAI, 1982), Tsushima was close to Yayoi, but Tanegashima and Taiwan were close to Jomon.

The characteristics of walking with different types of shoes were investigated from the viewpoint of ground reaction forces, as compared with those during walking barefoot. The shoes used in this experiment were three types for casual or business uses for men, which were on the market in Japan. The same shoes were worn by 4 male subjects of the same shoes sizes. It was concluded, from the analysis of variance and the mean difference test, that (1) the ground reaction forces during walking with shoes showed large differences between subjects, (2) the first peak value of the vertical ground rection force had the tendency to increase while the polar minimum value of the vertical force had the tendency to decrease during walking with shoes, (3) the effect of shoes on the ground reaction forces appeared subject specific, and (4) the formal shoes with leather sole had less effect to enhance the acceleration.

Recently, during a restudy of the fragmentary bone material of the Wadjak site two microliths were discovered. A description of these artefacts is given. A discussion is presented in the light of other Holocene prehistoric sites from Java, a supposed linkage between Wadjak Man and the Pacitanian, the fauna and suggestions about the age of the Wadjak site. These new finds fit with the view of Wadjak Man as Modern Man ("Proto Javanese"), found in association with the subrecent fauna from Java.
