The effect of storage on the water absorption by adzuki beans (Vigna angularis) was investigated with the four varieties harvested in 1978-1981. In some cases, during the first 11-15 hr soaking, the rates of water absorption by aged beans were greater than those by the fresh ones of the same varieties, but, after 24 hr soaking, the amount of water absorbed by the aged beans was smaller than that by the fresh ones in each variety. No correction was made for the loss of solids during soaking, so the water absorption curves obtained here are the apparent ones. The leakage of the soluble materials, such as coloring matters, electrolytes, minerals and sugars, from the aged beans was greater than that from the fresh ones. This difference probably arises from the deteriorative changes in the cell structures of beans during aging. The pH values of the leachates from the aged beans were higher than those from the fresh samples. This means the aged beans lost more minerals during soaking than the fresh ones.

This study was performed to make clear the influence of aging fatty soils to detergency of sebum on clothes. Refined lard free from antioxidant was used as a sebum model. The tested fabrics were three different cotton cloths, wool, polyester, acrylic and vinylon fabrics. Test-fabrics soiled with lard were hung in an incubator at the constant temperature for the fixed period, and then laundered. Lard which remained on fabrics was extracted with ethyl ether and determined by gas chromatography.
The results obtained were as follows :
1) The detergency of lard on cotton shirting decreased with increasing the aging period. The decreasing velocity was higher when the aging temperature rose. After it reached the value, which was nearly the same at any aging temperature, the detergency showed little change irrespective of increasing the period.
2) Correlation between the decrease of the detergency and the increase of the carbonyl value of lard on cotton shirting by aging seems to be obvious.
3) The decrease of detergency after aging was not recognized on synthetic fiber fabrics.

In this paper, working conditions in washing with brushes by human power was studied to enhance the experimental reproducibility as the first step. Through brush work under these working conditions, washing efficiency of 8 varieties of brushes having almost similar quality as those used in the previous report was studied.
It was shown clearly that the order of the efficiency coincided practically with the findings by the simple model experiments of the previous report.
The type of washing efficiency curve obtained according to change of locations of the brush on the soiled fabric surface corresponded more neatly with the accelerated curve rather than the speed curve according to the change of locations of the brush.
The order of the volume of detergent in the gaps of hair bundles of the respective brushes did not coincide with the order of washing efficiency of the respective brushes.

Five senior high school girls participated in determining the increase of dress-length suspension according to different armhole-heights of long sleeved one-piece dresses.
The results are as follows :
1) The amounts of suspension experimented with three different armhole-heights, i.e., 1/4 armhole, 1/4+2 cm armhole, and 1/4+3 cm armhole, show increase for all right arm motions tested.
2) For both side and front arm lifts, the amounts of suspension show no great differences in measures, and for the straight upward arm lift approximately show 2.7 times more than that of the first two.
3) Waist measure points for all three arm lifts show that the greatest suspension occurs on the right, and suspensions are followed by center-front, center-back and left waist-points, the ratio being 10 : 5 : 3 : 1 respectively.
4) An experimental guideline for amount of one-piece dress-length suspension was found.
Such results testify that amount of suspension caused by different arm movements must be given by some considerations in establishing armhole-heights for the construction of one-piece dresses.

Factor analysis was applied to anthropometrical measurements for garment planning of 902 boys aged from 7 to 18 yr. Factor loading values in each age group and effect of measurement item selection were examined.
The results are as follows :
1) In the age groups from 7 to 13 (except 9), where the growth is rapid, and in 17 and 18, where the growth is almost completed, the 1st factor loadings were large in height and length measurements (which represented body size), whereas the 2nd factor loadings were large in girth and depth measurements (which represented body thickness).
2) As for the age groups 9, 14, 15, and 16, however, the measurement items composing the 1st factor and those composing the 2nd factor were reversed.
3) For all age groups, the 3rd factor loadings were large in shoulder measurements and the 4th factor loadings in neck measurements.
4) It is important to balance item number on each part of the body, because the measurement items of 1st and 2nd factors replace each other during certain phase of growth.

For the purpose of analysing the relation between form of neck and those of bust and shoulder, principal component analysis was applied to the data (same as part 1) of three groups of 700 males aged 20-59 years, classified by “anterior chest width/shoulder width” index (group XN, x±1σ; group XS, less than (x-1σ); group XL, more than (x+1σ).
The results obtained by Varimax Rotation are as follows :
1) The first principal component of these three groups was interpreted as volume factor of body, and the third one represents a relationship between bust form and neck form.
2) The interpretation of second principal component was different in each group; it was the age that took effect on neck form in groups XN and XS, whereas, in group XL, it was the relationship between chest girth and neck base girth.
3) For the principal components of the first through fifth, the items which present high cumulative contribution ratio were different in each group. They are :
in group XN : chest girth, in group XS : chest girth and neck base girth, in group XL : neck base girth, shoulder width, posterior chest width and posterior neck base girth.
These items have to be took in consideration on the occasion of pattern planning which we perform in each somatotypological group.
