This study had the purpose to compare with development of fitness, motor ability and health among various living environments of the sea-side, the urban, and the mountain districts, where were situated at Nadachi town on the suburbs of Niigata Prefecture. Five hundred thirty-five children (aged 4-15yrs) were measured at the chidgarden, the fundamental school, and the junior high school. Measuring items of the physique were the height, the weight, the chest circumferance, the sitting height, and the foot area. Physical fitness tests were the muscular grip-strength, the lung vital capacity, the closed-eye single-leg balance, the dipping time of the upper extremity, the vertical jump, the standing trunk flexibility, the endurance run, and the pull-up. And, motor ability tests were the finger tapping, 5m shuttle run, 50m dash, and the ball throwing. As items of health inspection, the blood pressure (systolic and diasystolic) and the visual ability were adopted. As results of this study, following data were obtained ; 1) At the sea-side environment, development of the muscle power, the respiratory function, and the physique were showed much faster rate of growth at the childhood than that of the other ones, significantly (P< 0.01). 2) At the mountain environment, the arch-bend of the foot print only were appeared larger areas than that of the other ones, significantly (P< 0.01). 3) About the health inspection of the systolic blood pressure, children of both mountain and sea-side living districts were observed at higher pressure degrees than that of other urban environment, whose living causes whould be depended upon many different custom of food, nutrition, and resting ways. 4) Applying the statistical discreation analysis to those measured records of children, statistic distance between the physical fitness and the motor ability was obtained at the most longest order among various environments (P<0.001), while the distance between the health and the physique were shown as the most shortest one with the discreation analysis.

Effect of Ca Level on 65Zn Absorption at the Ligated Duodenal Loop of Rat Hiromi, GUNSHIN / Hiroshi, NAITO / Tadashi, NOGUCHI / Hidemi, TODORIKl / Takashi, AKAMATSU 1) Dapartment of Preventive Medicine, School of Medicine, University of the Ryukyus. / Department of Agricultural Chemistry, University of Tokyo. Tokyo 113. Japan Effect of calcium concentration on Zn absorption was studied in rats. Administration of Zn solution with calcium through gastric tructs depressed markedly the levels of Zn in serum taken from portal vein. Dependency on calcium concentrations of the absorption and distribution of Ca in the body was determined using in situ administration of Zn into ligated duodenal loop of rats. Administration of Zn with high calcium solution decreased significantly the levels of Zn in serum and all the tissues compared with the administration with low and medium calcium solutions. A considerable desease in the level of Zn was observed in the liver and kidney compared with the rats administered with medium and low calcium solutions.

The purpose of this study is to examine the basic data useful for more comfortable folk clothes of Korean women, with respect to their thermal insulation effect. The result of this study is summerized as follows, by comparing the caculated thermal insulation effect of Korean women's folk colthes with that of the western style clothes. l . The thermal insulation effect of the Korean women's folk clothes showed that summer clothes accounted for 0.67-0.93 Clo, while spring and autumn clothes showed l.09-1.20 Clo. 2 . Air layer had more effect on the thermal insulation of the Korean women's folk clothes than one of their material properties. 3 . The thermal insulation of the Korean women's folk clothes features higher effect in the lower part of the body as compared with one of the western style clothes, which acts as an important factor in the thermal insulation.

Recent reports have shown that a high ratio of waist to hip circumference (WHR) may be associated with a high proportion of intra-abdominal fat. The metabolic complications of obesity, which are associated with a high WHR, may therefore relate specifically to the amount of intra-abdominal fat. The purpose of this study was to determine if WHR is associated with the concentration of serum lipids that may predispose individuals to a higher risk for metabolic complications. Serum lipids concentrations were determined in 45 female subjects, ranging from 31 to 40 years in age, and WHR ranging from 0.71 to 0.98. Positive correlations of WHR with the ratio of cholesterol to HDL-cholesterol (r=0.641, p<0.001) and with triglycerides (r= 0.479, p < 0.001), were found, while a negative correlation existed between WHR and HDL-cholesterol (r= -0.600, p<0.001). In order to investigate the relationship between the fat distribution in the body and the serum lipids, the subjects were divided into two groups according to their % Body fat ; one group with a % Body fat more than 30 and the other with a % Body fat less than 30. The two groups differed significantly in WHR. In the group of obese women with high WHR (> 0.87), the ratio of cholesterol to HDL-cholesterol and triglycerides were higher and HDL-cholesterol lower than in the normal group with low WHR (<0.80). There was a significant correlation between the HDL-cholesterol concentration and the WHR (r= -0.869, p<0.001) in the obese subjects with high WHR. The serum triglycerides (r=0.688, p<0.001) was also significantly correlated with the WHR. In conclusion, this study confirmed that for the obese women, the WHR at a higher risk of metabolic complications assessed by the measurement of serum HDL-cholesterol and triglycerides levels was found to be 0.95.

The present study was designed to investigate EEG changes during two simulated 21 ATA hyperbaric heliox saturation dives. Four professional male divers were attached to 13 electrodes over the scalp and compressed to 21 ATA by helium. Thoughout the dives, EEGS were measured and stored on a magnetic FM tape recorder to calculate electroencephalographic to pograms. Three pattems of slow wave increase were clearly distinguished by the electroencephalographic topogram during compression. The first pattem was caused by trains or bursts of theta waves which spread from the frontal region to the central region of the scalp. This pattern occurred at comparatively shallow depth and showed the slowest recovery during the bottom stage among three patterns. The second pattern found in two divers was caused by frontal midline theta bursts, which showed maximum activity at F₂. The frontal midline theta bursts were augmented by a reaction time task. The third pattern was caused by vertex sharp waves which indicated a transition from sleep stage 1 to sleep stage 2. Neurophysiological meanings of these EEG patterns as well as the relationship between EEG changes and other indices were discussed.
