A study was made of the biodegradation of two watersoluble fluorescent whitening agents (FWAs); the disodium 4, 4'-bis (2-sulfostyrel) bephenyl (FWA-1) and the disodium 4, 4'-bis [(4, 6-disubstituted-1, 3, 5-triazin-2-yl) amino] stilbene-2, 2'-disulfonic acid derivative (FWA-2), each representing an important class of detergent fluorescent whitening agents.
The biodegradation of FWA-1 and FWA-2 were studied by two testing methods. One was similar to the testing method for biodegradability of synthetic detergent (JIS K 3363), and the other was that by activated sludge under aerobic conditions.
Under these conditions, considerable amounts of both FWAs were remained, whereas dodecene-1 derived LAS was almost completely disappeared to the extent that the methylene blue activity failed to indicate its presence.

We examined some dresses by sensory test to decide better conditions for the ease of bodice and sleeve. Four factors were picked up and were assigned into the orthogonal arrey of L₁₈.The judgements were transformed into cumulative frequency to perform analysis of variance.
The results were as follows :
1) The length of biceps produced a highly significant effect to the judgement of the sensibility of tightness.
2) Admitted conditions for the ease of bodice and sleeve were as follows :
ease for bust : 1012 cm, ease for depth of scye : 3 cm, length of biceps : upper arm circumference + 7 cm.

It is significant to fine better harmonious relation with the figure from the point of view of constructing the two color harmony space.
Two hundred and thirty-one kind of color combinating samples as to circle having equal area and each 36 samples constructing pattern of scale and rectangle were prepared by colored paper. These samples were evaluated with 5 kinds of bipolor scale relating to harmony by 53 panels. The constructions of color space based on these data were obtained using e_ij type quantificantion. The results were obtained as follows.
Two colors constructing in the relation of similarity match well. Olive and olive yellow show inharmonious relation in the combination of other colors. The form and color bear a relationship to one another.

It is generally said that the dietary custom is coservative. We can point out, however, that some changes are recognized in different aspects of food consumption. For instance, the food consumption in Japan are assumed to show the declining trend in the seasonal variations. This trend is often asserted especially in the case of fresh vegetables. But any quantitative investigation on this subject can not be found in literature.
In this paper, an investigation was carried out concerning such phenomenon in Japan, using the Annual Reports “the family income and expenditure survey” (1951-1978), which included amounts of monthly quantities of purchase. Number of foodstuffs employed in this investigation reached 153. As in the previous paper, the (modified) sample coefficient of variation was employed as an index of the seasonal variation. The linear regression of the index on the year was fitted for each item of foodstuffs, and the estimated regression coefficient was regarded as an index of the negative trend of the year-round consumption (i. e., the positive trend of the seasonal consumption).
Results obtained are summarized as follows :
1) The upper limits of 95% confidence intervals of the regression coefficient were less than 0 for the 72 species among 153. As for perishables, 32 species among 53 were revealed to be of the positive trend of year-round consumption.
2) Fresh vegetables, processed foods and non-alcoholic beverages were three groupes of foodstuffs, of which the high percentage showed the positive trend of the year-round consumption.
3) The sharpest trends were observed concentratedly for fresh vegetable under structure. This fact supported that the trend of year-round consumption was mainly led, as generally pointed out, by spread of growing in plastic greenhouses.
4) Unnegligible number, up to 33, of foodstuffs were revealed to be of the trend of seasonal consumption.
