To explain the effect of Suarai (rinsing with vinegar) on the preservation of fresh fish, some chemical and microbial determinations as well as sensory tests were employed.
The results were as follows :
1. Based on the determinations of volatile basic nitrogen (VBN), trimethylamine nitrogen (TMA-N), total aerobic plate counts (TAPC) and sensory tests, Suarai was found to be a very useful method for the preservation of fresh fish (saurel).
2. Effect of Suarai on the preservation of fresh fish (saurel) was demonstrated more clearly in dressed style than in round style.
3. Determination of pH-value gave no adequate index for the estimation of the preservability of fresh fish (saurel).
4. Production of histamine during preservation of fresh fish (mackerel) at 25°C was inhibited by Suarai.

The extractability of lipid for the pulverized bread irradiated with microwave was much less than that heated with electric heater, and lipid extracted from irradiated bread accompanied with it a large amount of non-lipid substances.
Cookies prepared from the dough preirradiated with microwave brought about fewer cracks and increased hardness, as well as decrease in the amount of lipid extracted.
The microwave irradiation of bread caused an increase in the amount of lipid specifically bound to other components in bread, with the resultant changes in nature of the bread.

Experiments were carried out to remove soil particles from the capillary walls of cloth by electro-osmosis. One of the most important problems in the experiments was to prevent the contamination from carbon electrodes. By using titanium plates as electrodes, the problem could be perfectly solved. The apparatus and method were as follows : A soiled cloth was held between two perforated plastic plates and dipped in a wash bath, and electro-osmotic flow took place when an electric field was applied perpendicularly to the cloth by using the titanium electrodes changing the polarity every 15 sec. Three kinds of soiled cloth, cotton cloth soiled with carbon black or clay and polyester cloth soiled with carbon black were used in the electrokinetic washing experiments, and their zeta potentials were measured by streaming potential method, by which the electro-osmotic flow rate in the capillaries was estimated. Experimental results thus obtained were discussed under the theory derived on the basis of electrokinetic, hydrodynamic and the DLVO theories as a first approximation.

A standard ironing speed of 3 cm/sec is specified for the care labelling of textile goods. In this paper, the temperature of multilayers of dry and of wet cotton fabrics was investigated, using both the cotton (165°C) and the high scale (210°C) setting of the iron. The following results were obtained :
1) When the iron was resting in its standing position, the temperature of the iron was lower than indicated by the dial. When the iron was in use, and the dial was set to the cotton scale, the temperature was higher about 10°C than the cotton level.
2) When the iron was stationary on the top of a 7-piece multilayer of dry fabric, the top layer reached the temperature of the iron, and the bottom layer was about 10°C lower in temperature. The temperature of a multilayer sample containing 30% moisture was lower about 10°C than the one in the case of dry sample, and a steam evaporation period was confirmed at 100°C.
3) When ironing at 3 cm/sec, the temperature of dry and wet samples were lower than those in the case the iron was stationary, and the steam evaporation period of the wet sample was longer.

Principal component analysis has been applied to 64 indices calculated from the anthropometrical measurements measurements of 700 adult Japanese males aged 20 to 59. As a result five factors were extracted and interpreted. Moreover individual principal component values for each factor were calculated, and their changes following age group were examined in order to know the total variation of body form in males.
The main results are as follows :
1) The first principal component could be interpreted as a lean-obesity factor, the second as a short-long trunk length factor, the third as a factor of the form whose variations had linear relations to age, and the fourth as a chest girth factor.
2) The strict tendency to become corpulent followed age was recognized. Long trunk was most remarkably observed in 40-44 years. The form whose variations had linear relations to age wholly changed in 35-39 years.
3) Age was found to influence the body form variation of adult males by following results : (1) as the third principal component, the factor of the form whose variations had linear relations to age was extracted, and (2) the lean-obesity factor extracted as the first principal component was deeply related to age.

It is object of this paper to fine change of image for exchange of color in blouse and skirt, and better relation from constructing color space based on harmonious rating in it's combination.
Sixty hundred and twenty-four kinds of combinating samples for 4 models were prepared by using the color simulator and SD method were used for harmonious rating. These data were analyzed by minimum-dimension analysis unordered class belonging and e_ij type quantification.
The results show that the visual impression of combination containing black and white are no change in exchanging color of blouse and skirt, but median grey is change. Color schemes which arrange light blue, light purple and other colors do not match well. Image of the color combinations consisting in these colors; light yellowish orange, dark green, bright yellowish green are affected by the individual character of the model.
