The effects of sodium dehydroacetate and sodium lauryl benzene sulfonate on protein biosynthesis in cell free systems of rat liver were examined.
The following results were obtained.
1) Sodium dehydroacetate stimulated slightly the incorporation of ¹⁴C-leucine into the total protein by post mitochondrial supernatant at the concentration of 5 and 10 mM, and inhibited by about 90% at the concentration higher than 30 mM. Sodium lauryl benzene sulfonate inhibited the incorporation by about 100% at the concentration higher than 2.5 mM.
2) Sodium dehydroacetate had little effect on ¹⁴C-leucine incorporation in microsome and cell sap systems at the concentration of 5 and 15 mM, and inhibited completely ¹⁴C-leucine incorporation at the concentration of 50 mM. Sodium lauryl benzene sulfonate inhibited completely ¹⁴C-leucine incorporation at the concentration higher than 2.5 mM.
These two additive had effects on the protein biosynthesis by two kinds of cell free systems of rat liver in the similar fashion to the effects observed on the liver slices.

Used oils, 57 samples collected from homes and 11 samples from food makers in Osaka area, were examined by the new method and by the conventional methods such as A.V., CO. V., I. V., and viscosity measurement. The new method involved the separation of polar (P) from apolar (AP) fraction by thin layer chromatography, determination of the absorbance of each fraction at 233 nm by a chromatoscanner, and calculation of P/AP ratio.
The ratios have been demonstrated to increase by increasing heat treatment of oils.
The results indicated that oils from homes were generally less deteriorated than those from food makers. The new method and the determination of viscosity were found to be more effective in the evaluation of heat deteriorated oils than the determination of A. V. or CO. V. in the present cases where both thermal-and auto-oxidation were involved.
There were obtained fairly good correlations between P/AP and A. V. (<1.0) or viscosities (<80 cp), but poor correlations between P/AP and A. V. (>1.0) or CO. V.

The effects of freezing and thawing, and of heating, furthermore, on the properties of yolks were studied in view of physical values and microscopical structures.
The following yolks were used : a) raw, b) frozen at-3--7°C for 24 hours, c) frozen at-3--7°C for 9 days, d) frozen at-24--29°C for 24 hours.
The results were as follows : 1. After thawing, b) and c) showed the same fluidity as a). But d) was gelatinized with higher physical values. As for heated ones, a) and b) were granular, and c) and d) were rubbery. Physical values increased after heating.
2. From microscopical observations, it was shown that a) consisted of polyangular granules. In b) and c), the structures disappeared with longer frozen time. The polyangular granules of d) were broken. The changes of structures by heating were not observed.
3. The property of yolk after heating was affected by the change of microscopical structure of yolk by freezing and thawing.

Experiments were carried out to investigate the viscous behavior of starch paste depending on the ratio of starch, sucrose and water. The viscosity of the starch paste was determined by the B type viscometer and Amylograph. The Scheffe's Simplex Lattice design for Multicomponent systems was used for the experiment.
The apparent viscosity, the flow behavior index, the yield stress, and amylogram were obtained. A linear relationship was found on full-log graph paper between the apparent viscosity measured by B type viscometer and the viscosity by Amylograph.
A quadratic equation was obtained for the ingredient ratio and the apparent viscosity and a special cubic equation was obtained for the gelation temperature and the maximum viscosity temperature. The tests demonstrated that these models were statistically satisfactory. The characteristics of these models experimentally obtained were shown by graphs.

Changes in rheological properties of a mixture of butter and wheat flour during cooking were studied.
Several samples were taken during cooking out of the roux mixture and their viscosities were measured with “Rotovisco RV-3” and “BH-HM Viscometer” at 60°C. The rheological properties of the roux mixture changed gradually from Non-Newtonian to Newtonian during cooking.
The final temperature of the cooking roux reached somewhere between 115°C and 165°C depending on the condition of the experiment.
Although heating and stirring were necessary for the changes in rheological properties of the roux mixture, stirring speed was not of significant effect.

Tests by wearing clothes of cotton tussore (white, green and black) were made under summer sunshine conditions. One-piece clothes made of cotton tussore with the same material but of different colors were used. As the subjects, 5 adult female students with similar sizes were selected. Test items were : skin temperature, clothes climate, moisture under clothes, and the sublingual temperature. It was proved by the experiment that the conditions of heat absorption showed considerable influence on skin temperature and clothes climate, revealing marked difference between white and black. By this experiment, it is verified that how to select materials of suitable absorption coefficients important in summer under direct solar rays.

In order to examine the fatigue phenomena experimentally and theoretically, the fatigue testing machine that simulates the repeated deformation during the wear has been developed by M. Niwa and S. Kawabata. By using this machine three kindsof Punto-di-Roma knitted fabrics (same as the ones used in Part 1) undergo repeated shear deformation under constant extension load.
The fatigue process is evaluated by measuring shear and tensile properties by KES-F 1 fabric testing machine. After such a cyclic deformation is applied, all the mechanical properties of the specimen are measured by KES-F fabric testing system and “Handle” of the specimen is also calculated by using those data and the equation.
The following results are obtained,
1) Shear and tensile properties change remarkably after about 10⁴ cycles of the repeated deformation.
2) “Handle” also tends to change to the lower quality after fabric is exerted thecyclic deformation.
3) Three kinds of fabrics differ in the amount of the change of the mechanical properties and “Handle.”
4) Water contained in the fabrics accelerates the fatigue.
5) Hysteresis properties of shear, tensile, bending and compressional properties are the important factors relating to the fatigue.

It was described in the previous report that the hue discrimination thresholds of the surface colors are affected considerably by both hues or dominant wavelengths and saturations (Munsell chroma). The present report shows the results of the experiments which were designed to examine the effects of lightness (Munsell value) on the hue discrimination.
Color specimens having Munsell values and chromas, 8/6, 6/6, 4/6 for 337 hues were prepared and used for hue discrimination experiment carried out in the same way as in the previous paper.
The results are as follows.
(1) The threshold discrimination of hue was affected by the difference in lightness. The dependence of the hue discrimination on the difference in Munsell values is similar with that on Munsell chromas.
(2) The color differences calculated with the formulas in the CIE 1964, Adams, CIE 1976 (Lab) and CIE 1976 (Luv) systems are congruous with the numbers of j. n. d. of hue discrimination in the series of our studies.

The washing resistances of resin finished fabrics were estimated by the infrared spectrophotometry and by the determination of nitrogen content in resins to observe the change of the amounts of resins remaining on the fabrics after repeated washings.
The results obtained by the above two methods were well agreed and summarized as follows :
1) Non-formalin type resin had a remarkably strong resistance on both cotton and regenerated cellulose fibers showing none of loss of the resin even after 25 time-repetitions of washing. Less-formalin type and other glyoxal type resins exhibited weaker resistance on regenerated cellulose fibers than on cotton fiber. Melamine type resin showed a favorable resistance even on regenerated cellulose fibers, while washing resistance of urea type resin was unfavorable. Insufficient curing gave considerably lower resistance in all cases.
2) Washing resistances of commercial resin finished fabrics are briefly classified into 4 grades. 50% of these fabrics belong to 2nd grade, showing 20-30% reduction after 1st washing followed by little change thereafter.

A new method to decide an amount of an ease across a collar of a Kimono is described in this paper. According to this method the amount of the ease is fixed by a body style, thickness of the collar, characteristics of a fabric and a collar style. Influences of the fabric, the collar style and a measure of an agarikurikoshi on the amount of the ease have been discussed. The results obtained are as follows :
1) The smaller a Young's modulus of the fabric in the bias direction, the larger the amount of the ease. But it hasn't so much effect on the ease.
2) The amount of the ease becomes smaller in the order, a standard collar, U-type collar and V-type collar.
3) The agarikurikoshi has little effect on the ease.

As a part of the housing problems of a specific group in Japanese society, this study investigated the way of life and housing needs of students, and a proposal to solve the problems facing them was made.
The present situation of students' life and the actual conditions of their commute daily to the school and back to their own homes are as follows :
1) In general, students are of unmarried status, without a permanent source of income, having more personal free time than other social groups in Japanese society.
2) The duration of time taken from home to school for more than half of the students surveyed has proved to be over 90 minutes, whereas for a little less than 30 percent of the surveyed group, it takes over 2 hours.
3) Such an extended period of time spent travelling back and forth between home and school results not only in fatigue but is found to have a particular effect on students' extra-curricular (club) activities.

Within the context of Part 1, the following is an analysis of the way of life (physical and economic) of the students accommodated in boarding houses.
1) Considering the form of dwelling unit in which students live, 40 percent of students rent a room in a private home and another 40 percent are found to be living in apartment houses. Those living in apartment houses for students only have increased in number.
2) Half of the boarding house students pay a returnable deposit and a non-returnable. 50 percent of the rent for rooms ranges from 6, 000 yen to 7, 000 yen a month, and 75 percent of rooms rent at no more than 10, 000 yen.
3) Although most students live in rooms of four and a half mats in size, the desirable minimum space is about six mats including closet.
4) 69.5 percent of the boarding houses have cooking facilities, 30.3 percent have a bath room, and 76.1 percent of boarding house students use washing machines.
