Five kinds of experimental fats with different P/S ratios were fed to rats for 3 weeks. The rat's plasma and liver lipids, and the fatty acid composition of their plasma, liver, testes and epididymal adipose tissues were determined. As the P/S ratio in these dietary fats decreased, the levels of cholesterol and phospholipids in the plasma decreased, while the plasma triglyceride level increased. The plasma HDL-cholesterol level and liver lipids were not significantly different among the experimental groups. The proportion of linoleic acid (C_{18 : 2}) and arachidonic acid (C_{20 : 4}) in the plasma, and the proportion of C_{18 : 2} in the liver and epididymal adipose tissues increased as the P/S ratio in dietary fats grew. However the proportion of each fatty acid in the testes remained constant in spite of the change in the P/S ratio. The C_{20 : 4}/C_{18 : 2} ratios of the rat's liver and testes varied in response to the change of dietary P/S ratio, but those of plasma and adipose tissues did not.

This study was made to compare the preventive effects which among eight separated parts of Job's tears had on hyperlipemia. Fifty-four male-SD rats were divided into nine dietary groups of leafstalk, root lipid free, bran, albumen, malt, bran lipid free, bran lipid, green powder (GP) and control. Rats of eight groups were fed for 2 weeks with one of synthetic diets cotaining mixture of separated parts of Job's tears in a 20 % ratio by weight. The results obtained are as follows :
1) The food efficiency ratio at the 2nd week after feeding was lower in the root lipid free, GP and bran lipid groups than in the control group, whereas, the ratio of body weight gain was not significantly different in the all groups.
2) Serum total cholesterol level was lower in the bran lipid and GP groups than in the albumen group. HDL-cholesterol level was higher in the root lipid free, bran, albumen, malt, bran lipid free, bran lipid and GP groups than in the control group. The atherogenic index was lower in the albumen, malt, bran, lipid free, bran lipid, and GP groups than in the control group. The serum total lipid level, liver total lipid, triglyceride and cholesterol level in GP group tended to be reduced in comparison with the other eight groups. These results suggested that the composition of serum and liver lipids in the GP group was better than the other Job's tears fractional groups.

The effect of temperature, U. V. irradiation were carried out in the anthocyanin pigments (ANs) extracted from purple yam (UBE) and papilionaceae (PA) stored in air and nitrogen. The results obtained were as follows.
1) After storage for 23 days, the colorant remaining ratio of UBE and PA ANs solution heated to 30°C was 97 and 77 % while that of the same heated to 60t was 61 and 30%. When heated to 90°C, UBE and PA ANs showed the lowest colorant remaining ratio.
2) After storage heated to 60°C for 23 days, the colorant remaining ratio of UBE and PA ANs stored in ampule (air) were 62 and 30 %. But both ANs stored in ampule (nitrogen) was more stable at 85 %.
3) UBE and PA ANs solution was irradiated direct with a sterilizing lamp for 6 hr. As a result, the colorant remaining ratio of both AN were 20-30 %. But UBE and PA ANs in ampule showed the highest colorant remaining ratio of 95 and 100 %. However, both AN stored in outdoor decomposed for 4 days.
4) Several kinds of additive were added to UBE and PA ANs solution, and the obtained solution was heated. As a result, both AN decomposed paticularly with L-ascorbic acid and hydrogen peroxide.

Muscle sample was heated in a boiling water bath for 0.5-3 hr in order to investigate the protein components in soup stock. Sarcoplasmic protein and non-sarcoplasmic fraction separated from muscle sample were heated to clarify the origin of the protein components in soup stock. The soluble proteins after heating were investigated quantitatively and examined by using of SDS polyacrylamide gel electrophoresis. There were three proteins mainly with estimated molecular weight of 40, 000, 23, 000, and 10, 000 daltons in soup stock. When sarcoplasmic protein was heated, the 10 % of original protein was soluble in water. And the concentration of soluble protein separated from heated non-sarcoplasmic fraction increased with an increase of heating time. It was fround that 40, 000-dalton protein and 20, 000-dalton protein were revealed in soluble fraction of heated non-sarcoplasmic fraction, and that 10, 000-dalton protein was revealed in it of heated sarcoplasmic protein and heated non-sarcoplasmic fraction.

Sebaceous substance and sweat constitute an acid grease film on the skin. This acid grease film protects the skin from dryness and bacteria propagation. This film, on the other side, causes the soil of clothing by mixing with dust in the air and stratum corneum dropped off the skin. In the climate chamber we studied the relation between the environmental climate and sebaceous substance or sweat excreated from the skin in the space of clothing and skin. We also measured the quantity of squalen in sebaceous substance by osmic acid method and the quantity of sweat by water blue method. The results were as follows :
1) Sebaceous substance and sweat from the skin were effected by not only air temperature but air humidity.
2) A squalen spot excreted on the forehead was larger than the one on the chest in size and it linearly increased with air temperature.
3) Number of squalen spot (n/cm²) was increased by about 6 % in proportion to the increase of the skin temperature by 10 °C in 80 % R. H.
4) The quantity of sweat excreated on the chest was more than the one on the arm and the forehead.

For the purpose of analyzing compressive property of the human body, the compressive stress-strain relations were measured on the forearm, the upper arm and the thigh with the dynamic method. Assuming that the human body is a linear viscoelastic substance under specific conditions, the modulus of elasticity and the coefficient of viscosity were calculated. The modulus of elasticity and the coefficient of viscosity increased with compressive strain and varied according to the different points of the body.
The influence of garment restraint upon compressive properties of the human body was also estimated. Measurements were conducted before and after restraint on the upper arms of 3 subjects. After the restraint, a slight increase in the compressive hardness was observed, which would depend on the degree of restraint.

The purposes of the investigation were 1) to assess perceived importance of clothing norms, 2) to ascertain any significant differences existed in the level of the perceived importance (LPI) between female college students and middle-aged women, and 3) to examine relationship between the level and need for uniqueness (NFU). The sample was composed of 206 students and 161 middle-aged women. A scale was devised for the evaluation of LPI consisted of 7 factors (school uniform, clothings related to occasion, office, sex, age, modesty and Kimono). Subjects were asked to rate each statement on the clothing norms under two kinds of instructions : their attitudes (ATT) and their beliefs about the expectations of others (BEO) toward clothing norms.
The results revealed that discrepancy scores of ATT and BEO of the students were higher than the scores of the middle-aged women, and the former had more free attitude to the norms as compared with the latter. The NFU was measured by the 28 items developed by Okamoto. Based on the sum scores of the NFU, the students and the middle-aged women. were separately segmented into “high, medium and low” NFU groups. Significant differences in the discrepancy scores among the 3 NFU groups were found on five of the seven norm factors, and in each factor the mean discrepancy scores of the high NFU group were higher than those of the other groups. Analysis of variance also showed that significant differences existed among 3 NFU groups in ATT scores af all items, but did not in BEO scores. The findings indicated that the differences in the ATT scores mainly contributed to the differences in the discrepancy scores described above.

The purpose of this paper was to grasp the actual conditions of the family-communication objectively from the view-point of activities and time in daily-life and to draw factors that influenced them. Moreover the family-communication housewives regarded was demonstrated from the relation between their consciousness and actual conditions.
The results were as follows :
1) Housewives thought they had about 2 hr-family-communication on an average. It corresponded to hours that all or all except one member of the family gathered in LDK-space, and contained hours that they participated doing their household matters (“Nagaraparticipation”), which was recognised as the family-communication hours but they weren't so satisfied with.
2) In the case of the multiple-house the difference between the family-gathering hours and the family-communication hours were larger than that of the detached-house. So it was supposed that LDK-space in the multiple-house was used more variously.
3) The family-communication hours in LDK- space were influenced by the number of rooms and life-stage. It became short when there were many rooms and oppositely became long when there were few. When children were little or grown-up, it was long, and when they had children going to junior high school or high school, it became shortest.
4) The closer L, D and K were united, the longer the family-communication hours got. Completely separated D, K from L (Separate-type), housewives' “Nagara- participation” were interrupted. It was desirable that the living style which interrupted others' eyes looking into K from L to the extent that the housewives' participation to the family-communication wasn't interrupted.
