Effects of the exercise on lipid metabolism of rats were studied. Thirty-six male-Wistar rats were divided into three half-synthetic diet groups of Kinako, egg and milk. The Kinako group was fed with the diet of mixture of brown rice 2 and Kinako 1 in weight ratio. Eggand milk-groups were fed with the diet of animal protein ratio 50%, which was prepared by replacing some part of Kinako with dried-whole egg or whole-milk powder. Each of these three groups was subdivided into sedentary group (NE) and forced swimming (30 min/day) group (E).
Rats of the six groups were fed during the period from the 5-th week after birth to the 16th. The results obtained are as follows :
1) Body weight and adipose-tissue weight are lower in E than in NE for the Kinako- and egg-groups, whereas, for the milk group, no significant difference was found between E and NE groups.
2) HDL-cholesterol level, α-lipoprotein (α-Lp), and α-Lp/ (β-Lp+preβ-Lp) were higher in E than in NE for all the dietary groups.
Total cholesterol, triglyceride and total lipid level in serum were lower in E than in NE for egg- and milk-groups. No difference in α-Lp was found among the dietary groups, while preβ-Lp was found to be significantly lower in Kinako group than in egg- and milk-groups. These results suggested that synthetic fat in the body of Kinako group was lower than other two groups.

Soybeans were boiled, innoculated with Bacillus natto IAM 1114, and incubated at 37°C for 24 hr. A protease to be produced by this microorganism was homogenized in a phosphate buffer, pH 7.0, and the supernatant submitted to (NH₄) ₂SO₄ fractionation. A 30-80% saturation with respect to this salt was chromatographed on DEAE-Sephadex A-50, Sephadex G-100, and CM-Sephadex to obtain a partially purified protease fraction. Experiments with the purified protease showed that it had an optimal pH of 7.0 in hydrolysis of casein used as a substrate. Investigations with specific inhibitors and others indicated that this protease belonged to a subtilisin family. It is noted that the protease had an activity of effectively hydrolyzing a soy protein isolate used as another substrate.

The effect of the type of beater was studied on the texture of butter sponge cake. Wire chef's whip beater (A) and two rotary type beater (B) were employed. Six kinds of sample of various batter mixing periods were prepared using these two types of beater.
The longer the mixing period of batter, the larger were the specific gravity and flowing volume of batter. Both of these values of B samples were larger than those of A samples. Negative correlations were obtained between the specific volume of cake and specific gravity of the batter, and between the specific volume of cake and flowing volume of batter. Hardness, gumminess and chewiness values of B samples were 1. 4 times bigger than those of A. Negative correlations were also found between these three texture parameters and the specific volume of cake. A samples were preferred organoleptically and negative correlations were obtained between mouthfeel and the three texture parameters.
These significant differences between the two types of samples in both texture and mouthfeel suggest that the type of beater clearly affects on the texture of butter sponge cake.

The basic mechanical properties of twisted yarn-twistless yarn composite fabrics were measured by using the KES-F fabric testing system and their hand values were calculated by using these mechanical data. The characteristic values of fabrics except for linearity of load-extension curve, geometrical roughness and weight are influenced by whether warp yarns are twisted or twistless and by twistless yarn content in weft direction. The values of the primary hands such as Koshi and Fukurami increase with mean twistless yarn content of warp and weft. The total hand values (THVs) of composite fabrics are equal to or slightly higher than those of twisted and twistless fabrics. The tensile, bending and shearing properties of composite fabrics when compared with those of twisted and twistless fabrics suggest that mixing of twisted yarns and twistless yarns works in the favor of men's winter suiting materials. It is predicted that a mixture of twist warp and twistless weft has good appearance and high THV and twisted and twistless fabrics have poor appearance, in spite of their high THVs.

To elucidate the dyeing and diffusion behaviors of indigo for cotton and silk, we analyzed the adsorption isotherms obtained by the equilibrium dyeing and diffusion profiles obtained by the film roll method.
The adsorption isotherms apparently were of the Freundlich type, so the standard affinities of indigo and dibromoindigo for the substrates were determined from the equation of the Freundlich adsorption isotherm. The standard affinities decreased in following order : cellophane>cotton>silk.
The several diffusion profiles of indigo and dibromoindigo for these substrates had a shoulder part. Therefore, it seems that these dyes diffuse into the substrate by the mechanisms more than one. The diffusion profile can be divided in the ionic diffusion and nonionic diffusion. The former corresponds to the diffusion of the leuco compound and the latter corresponds to that of the non-reduced indigo and oxidation compound formed in the substrate.

The comfortable clothesform in very low wind is no longer effective under the increasing velocity of the wind. The author compared the influence of air velocity upon the human body in denim skirts wear with that in pants wear, setting the velocity of the wind for 0.2, for 0.5, for 1.0, and for 2.0 m/sec under 18°C air temperature and 50% relative humidity.
The subjects are four healthy women who are 21 years old. The instruments measured for the wind were an “Anemotherm Airmeter, ” a copper-constantan thermocouple for the skin temperature, and a minima sharp thermo-hygrometer for the temperature and relative humidity within clothing.
The results are as follows : in the case of the desk-work, the mean skin temperature was lower in pants wear than in skirts wear. This difference between the skin temperature in pants wear and that in skirts wear was notable under more than 1.0 m/sec velocity of the wind. In skirts wear, the mean skin temperature decreased abruptly under the 2.0 m/sec velocity of the wind. The differences among individuals were notably observed on the femora both in skirts wear and in pants wear under the 1.0 m/sec velocity of the wind.

The purpose of this paper is to understand what kind of consciousness senior high school students show toward wearing prescribed uniforms, if any differences of consciousness can be found among them, and if any could be found, what the differences are and what factors affect the differences.
Nine hundred and eighty samples (442 males and 538 females) from ten high schools (public and private) in Mie Prefecture were collected.
The results obtained are as follows :
1) Concerning a practical function, uniforms are of great convenience but physiologically and hygienically, they are of no good. Their symbolic function is given only a low estimation. Aesthetically uniforms are thought to be void of beauty and freshness and of no pleasure to wear.
As to the rule that regulates to wear uniforms, students take it for granted and have no doubt about it, but they don't see any necessity of being purnished when they break the rule.
2) The axes with which to judge what kind of consciousness students display toward uniforms are (1) if the students' evaluation of uniforms' symbolic function is high or low (2) if they consider to have uniforms desirable or if they have no clear view of them.
3) The factors that affect the students' consciousness toward uniforms are their way of clothing, school and home lives. Also individuality of each student much affects the consciousness.
