Kanisuki is the one of the methods for cooking snow crabs (Zuwai-gani) to relish the meat and the stock. Male snow crabs (Ma tsuba-gani) is usually used for Kanisuki. The molted male snow crabs with soft shell (Mizu-gani) and female snow crabs (Oya-gani) are seldom used for Kanisuki, because those crabs are poor in flavor.
We cooked these three kinds of crabs as Kanisuki. The content of the stock essence was in-creased during the cooking, however, the increment was not time dependent. The arginine, glycine, taurine, proline and alanine were the major free amino acids found in the stock and in the muscle extract. The content of the hydrophobic amino acids in the stock was high at the beginning of the cooking with Matsuba-gani. However, the latter stage of the cooking, the amino acid composition was very similar to that of the muscle extract. The crab muscle obtained at middle stage of the cooking was most favored by the panels, even the amino acid content was less than the early stage of the cooking.

“Misozuke” is a traditional Japanese fish product where fish meat is cured in Miso. Experiments were carried out to investigate changes in texture and proteins of fish meat cured with Miso. Frozen meat fillets were cured in Miso at 4°C for 28 days. By the sensory test, the meat was found very hard after 3 days curing and then became tender after 21 days. The hardness values of the texturometer test varied parallel to the sensory tests results. The Miso-cured meat became more fracturable on homogenized in water during preservation. The proteins of the Miso-cured meat extracted with 0.45 M KCl-phosphate buffer solution did not show appreciable change from 1 to 28 days. The SDS-polyacrylamide gel electrophoretic patterns indicated that myosin heavy chain of Miso-cured meat was broken down into fragments with low molecular size during preservation. The wahoo actomyosin was stored with crude enzyme extract of Miso and its components like myosin heavy chain and tropomyosin were decomposed after 1 day storage at 4°C. The decomposition was attributed to the proteolytic enzymes of Miso. The texture changes of Miso-cured fish meat were due to the decomposition of fish meat proteins.

Changes in preference for food colors by age and sex were s tudied using 1, 112 male and 1, 164 female students ranged in age between 12 and 20 years. Nine colors, red, orange, brown, yellow, yellow-green, green, blue, purple and pink were submitted for the preference survey.
Total of 69.9% of the males and 82.0% of the females recognized that food colors influenced their appetites. The percentage varied significantly between under 16 year-old and over 17 year-old subjects. The percentage was larger for elder than younger subjects.
Orange and red were preferred and blue and purple were not preferred, suggesting that warm colors stimulated the appetite more than cold colors. Significant differences were observed in standard deviations for rated preferences between the males and the females, and among respective age groups. The elder females showed smaller values of standard deviations than the younger females, meaning that they had similar color preferences. The males showed larger values than the females.

Photo-deterioration of natural fibers (silk and cotton) at the early stage was surveyed with regard to the changes of physical properties and chemical structure of the fibers.
Photo-deterioration at the initial stage brought about yellowing and lowering of elongation and strength for both fibers. The changes in elongation and strength of silk induced by UV light, xenon lamp, and sun light showed that the steep decrease occurred at the early stage, followed by the gradual decrease in both strength and elongation, the latter being more remarkable than the former. However, for cotton, the decrease in strength was more pronounced than that in elongation and both changes were smaller as compared with silk. Furthermore the changes in elongation and strength of cotton were simply proportional to exposure time.
Regarding the changes in chemical structure, the formation of carbonyl groups by oxidation of cotton fibers was confirmed by copper number measurement. With silk the decrease of tyrosine and tryptophane was found and related to yellowing phenomena.

Influence of various inorganic builders on the fluorescent brightening effect of FBAs in built detergents were investigated. Experiments were mainly focused on : (1) the effect of each builder on the exhaustion ratio of FBAs and the maximum reflectance of washed clothes, the total effects of model built detergent.
The results obtained were as follows :
1) The effects of each builder. The effect of water hardness for zeolite is very remarkable. As the concentration of zeolite increases, the exhaustion ratio of FBA decreases markedly.
On the other hand, the effects of sodium tripolyphosphate and sodium sulfate increase with the increasing of concentration when used 0° DH water or low hardness water. The effect of sodium carbonate is not so remarkable because of the concentration of Na₂CO₃ is very low.
The influence on the maximum reflectance (whitening effect) of each builder is not so remarkable with compared to the difference of the exhaustion ratio.
2) When the all sorts of builders were formulated in a model built detergent, the characteristics of each builder appears to put together, and higher whitening effect were obtained as overall results.

The change in structural lines of basic skirt pattern, in relation to the change of body shapes, was studied.
The method was similar to that of Part 1. Subjects were 50 elderly women in average age of 68.6 years old.
The results obtained were summarized as follows :
1) The increased values of the width of front and back skirt pattern against hip girth were 4.6 (average value), 9.8 (maximum value) and 0.7 cm (minimum value).
2) As waist girth and middle hip girth increase remarkably in elderly women comparing with young women, their middle hip girth corresponds to the maximum girth of hip part, therefore, dart should be designed with narrower width and shorter length.
3) Formula below was the correlative linear equation on middle hip girth (y) to waist girth (x).
y=0.92x+22.4 (r=0.87)

The concerns for sportswear and the attitudes toward sports were measured.
The results obtained by factor analysis are as follows :
1) The factor structure of men's concerns for sportswear are interpreted as (F1) the ardent desire for fashionability of sportswear, (F2) the fashion taken in advance.
The factor structure of women's are interpreted as (F1) the consciousness of others, (F2) the enjoyment of shopping, (F3) mentation, (F4) the functionality of sportswear, (F5) the ardent desire for fashionability and functionality of sportswear.
2) The factor structure of men's attitudes toward sports are interpreted as (F1) the training of mind, (F2) the pursuit of victory, (F3) sports for show, (F4) bringing-up youth. The factor structure of women's are interpreted as (F1) the training of the Olympic spirit, (F2) bringing-up youth, (F3) the pursuit of victory, (F4) the desire for human nature and preservation of health, (F5) alleviating stresses.
3) As a result of the correlation coefficients between the factors of concerns for sportswear and the attitudes toward sports, it was found that in women there was a linear relationship between the training of the Olympic spirit and mentation (γ=-0.443), between bringing-up youth. and the functionality of sportswear (γ=-0.388), between the desire for human nature and preservation of health and the ardent desire for fashionability and functionality of sportswear (γ= 0.400), between bringing-up youth and the enjoyment of shopping (γ=0.518).

This study analyzes the new housing demand, which is different from the usual housing demand for getting better conditions by moving one residence to others.
The research findings are as follows :
1) Residents moving inside Ibaraki Prefecture are the younger families with the householders in their thirties and moved from rented houses to detached ones. This is the usual pattern of housing demands for getting larger residences.
2) Most residents from the metropolitan area are those who come to get their new jobs in neighboring area because of getting the detached houses at the very cheaper prices, and many of the householders are around forties. But a lot of dissatisfactions are found among them. These are the dissatisfactions to the new jobs they have got and to the new houses. So the new houses do not come up to their expectations as permanent residences.
3) Families who come from metropolitan area after retiring jobs are satisfied with the new houses and wish to live as long as possible.
