Frozen whale meat on the market was examined histochemically and electron-microscopically in comparison with fresh beef. The results obtained were as follows :
1. Granular glycogen was found in the protoplasm of the beef, but not in that of the whale meat.
2. The karyotin part was somewhat vague, and cavities of mitochondria were found there.
3. Some collapse was observed in the filaments of the protein in the muscular fibers. It is considered to be an indication of the collapse of the physical structure of protein molecules that the meat is dyed well by means of the acrolein·Schiff reaction.
4. These changes observed were so slight that they were considered to be ineffective to reduce the food value of the meat. Therefore the frozen storage of whale meat might be regarded as the approvable measure.

Fluorescent brightening of polyester-cotton blend is carried out by dyeing polyester part first with disperse type dye, and then cotton part with direct type dye.
Brightening effect of this combination method, however, is not always satisfactory, and under a certain condition, fluorescence even decreases after the second process of dyeing.
In order to make clear the mechanism and find out the effective process of combined brightening, the authors have studied the reflectance of polyester-cotton blend, polyester and cotton cloths treated with disperse dye (Uvitex ERN), direct dye (Whitex BK) and both dyes in successive way. respectively, as well as with the soaping prior to the second dyeing.
Main results obtained are as follows :
1. The disperse dye absorbed by cotton in the first process had no effect on the amount of direct dye taken by cotton in the second process, but affected the final fluorescent intensity.
2. The more the soaping cycles were made, the better the brightening effect was obtained.

What worries a mother most is the treatment of the excrement of her infant, and it is an important element of the health care for the infant. When an infant is left with a wet diaper, the diaper tends to draw heat from the body and the water evaporates or the diaper dries up. To understand this process clearly, two kinds of experiment were performed.
1) The temperature fall in a model, A, of baby's lower half body which put a dry diaper and another similar model, B, with a wet diaper was investigated as the time went on. After 2 hours, it was found that the fall of the temperature in model B was greater both inside the body model and on the surface than in body model A.
2) The process of drying of the wet diaper was also investigated, and it was observed that the diaper rapidly dried up as the time proceeded. The microclimatic study showed that the temperature between the diaper and body fell while the humidity rose.
Through the above-mentioned observations, it has been confirmed that a wet diaper has an unfavorable effect on the health of an infant.

In this report 319 junior high school girls were divided into two groups by their thumb-lengths and sewing needles of four different lengths were tested by these two groups in order to find out the most effective length of the needle.
The sewing efficiency was evaluated by the length of cloth sewed in a certain period of time, number of stitches and their uniformity.
It has been disclosed that the most suitable length of the needle was 60+5% of the thumb-length for junior high school girls to increase the number of stitches and the length of sewed cloth in a given time.
So far as the improvement of the uniformity of stitches is concerned, a needle a little longer than that mentioned above, in other words 65±3% of the thumb-length, was most suitable.

To solve the problems in sewing the pre-cured shirts fabrics, the polyester fabrics blended with cotton fibers were chosen and the suitability of 21 kinds of sewing threads made of synthetic orcellulose fibers and 3 kinds of No. 9 needles with different kinds of finish were investigated.
As the results, it was disclosed that, when the sewing conditions were satisfactory, the great factors which affected the quality of stitches of the pre-cured fabrics were the irregularity of sewing thread, the coefficient of friction of threads, and the roughness of the needle surface.

There are several ways in which we wear Japanese clothes beautifully and fittingly. It is of great importance that a kimono-collar be sewed appropriately.
Therefore the experiments were carried out from the standpoint of suitable placing of kimono-collars using sixteen kimonos with different kinds of kimono-collars.
The difference in kimono-collars is caused by the combination of the following factors.
1. The cutting-line for placing a kimono-collar onto the kimono.
2. The distance from the shoulder-line to the kimono-collar's central point.
3. The flexibility of the cloth.
As the results, it was made clear that the proper placing of the kimono-collar is more closely related to factor 1 than factors 2 and 3.

In order to grasp the human relationship to the neighborhood society, the relationship between neighborhood families was investigated.
A questionnaire was administered in July, 1969, to the parents of children of primary and secon dary schools which were selected from seven areas in Aichi Prefecture-commercial, industrial, residencial, modern residencial (apartment houses), farming, mountainous, and fishing areas. 3184 samples were obtained.
In general, the social connection with the neighborhood is limited compared with the social connection with relatives. But most families pay a visit of courtesy to their neighborhood. More intimate social connection is often established in mountain villages, but it is also true that discontent about human relationship is fostered among those villagers as their contact becomes close. On the other hand, in cities the social connection with the neighborhood is made for formality's sake ; they have discontent about their environment.
In any case, more than 70% of the questiones have been satisfied with the present situation and wish to live in amity with the neighborhood.

In the previous paper, private social connections with the neighborhood was investigated. In this report, public social connections of a family with local cooperative organizations-a town association, a village block association, a self-government organization-were discussed. The method of the examination was the same as in the previous report.
In general, people do not fully recognize self-government organizations, and are indifferent as to how the dues are spent. But they show vivid interest in the amount of contribution, and they decide it through the consultation of husband and wife. This tendency increases when both husband and wife have occupations.
More people in agricultural areas participate in the activities of self-government organizations than city people. The duties to self-government organizations are usually performed by husbands in agricultural region and by wives in cities. This tendency tells us that there is a difference by regional areas between functions and characters of the self-government organizations.

We tried to learn the actual lives of wives working on part-time basis, their reasons for being employed, and the influence on their housekeeping, and to make some remarks about the facts obtained.
The author selected fifty working wives out of the employees of two department-stores and another 50 out of a factory in Sendai area to administer a questionnaire in the middle of April, 1969.
Our analysis shows that :
1. The purpose of working wives as department-store sales-assistants is mainly to make use of their spare time, and factory-workers to supplement their domestic economy.
2. Extra-income earned is used to improve their household, to pay their debts, to increase their savings, and so on.
3. Everyday housekeeping is also managed and performed by them, similarly to non-working wives. Being employed on part-time basis, however, they are discontented with much less free time for domestic tasks and others.
4. Their households can scarcely be well kept, if working hours per day is less than five hours. If working wives are going to manage sufficiently both their household and outside job, they have to simplify housechores and work very efficiently.

This investigation has been made to clarify the educational value given to the subjects of Homemaking and to improve homemaking education.
In Part I, a questionnaire on subject items of homemaking course of junior high schools was administered to 968 persons and those items were graded into five ratings. The results of the analysis of the data are summarized below.
1. It has been recognized that the value of the subjects in junior high school homemaking education is high for girls. The items which have high score for girls are Home Management and theoretical application of Food, Clothing and Child Care. (Table 3, Fig. 1)
2. The value of the items of Housing is recognized as higher for boys than for girls. (Table 4, Fig. 1)
3. Analysis of variance of the mean values shows that there are more variances between teachers and pupils or pupils and parents than between teachers and college students or teachers and administrators. (Table 5)
4. The group which recognizes the highest value of the homemaking education is that of teachers of Homemaking ; the second, administrators ; the third, college students ; the fourth, pupils ; and the group which respects the lowest value is parents' group. Each group respects somewhat different phases of Homemaking. (Fig. 2)

In Part 2, the data was collected by administering a questionnaire to 1878 persons on the subjects of homemaking course of primary schools. The results of the analysis are summarized below.
1. The value of homemaking subjects is recognized as high for both boys and girls in fifth and sixth grades. Variance of the mean value of each item is smaller than that obtained by the study on junior high schools. (Table 2, Fig. 1)
2. The mean value of grade of each item given by primary school boys is lower than that by girls, and the difference between the two is rather great. Children highly respect Family Relations and the management aspects of Housing, Clothing, and Food. (Table 2, Fig. 1)
3. Analysis of variance of the mean values shows almost the same results as reported in Part 1. (Table 4)
4. Five groups of the questiones show approximately the same results as reported in Part 1, but the value given by parents is not as low as reported in Part 1. (Fig. 2)
