The physical state of carotenes in the product prepared by lactic fermentation of the skimmed milk and the carrot juice, was investigated spectrophotometrically.
The state of existence of β-carotene in the lactic fermentation product differed owing to the preparation, and the products obtained from fresh orange carrot (Seiyo-Ninjin) and from microwave-heated one had the carotene in the crystalline state, while that from the same carrot ordinarily heated in boiling water had the carotene in the lipid-dissolved state.
In the case of red carrot (Kintoki-Ninjin), only the product from fresh carrot had the carotene and lycopene in their crystalline states, and the two other cooking methods changed the state of the carotene from crystalline to lipid-dissolved, the crystalline state of lycopene remaining unchanged.

Skin lipid stuck to the underwear worn by 26 senior high school boys for 24 hr under the ordinary living condition was extracted with benzene, and determined by the same method mentioned in the previous paper. The results are shown by mg stearic acid equivalent to skin lipid per 100 cm² of the cloth.
The results are outlined as follows :
1. The amounts of skin lipid on 16-17-year-old senior high school boys' underwear distribute widely ranging from 2.25 to 70.50 mg and the distribution has the mode at 13 mg. The skewness that indicates departure from the normal distribution of the data is +1.75.
2. The distribution range and the mode of the amounts of skin lipid on senior high school boys' underwear are about twice the width and the quantity of those of 13-14-year-old pupils', but they are very similar to those for women's college students'.
3. The amount of skin lipid on boys' underwear shows a rapid rate of increase during they grow to 16-17 years old from 13-14 years old.

The physical properties of sewing thread, waxed and untreated, were studied in the previous report. From this experimental work it was found that the tensile strength of waxed thread was greater than that of untreated one. The present paper discusses the effects of laundering and sewing on the strength of waxed thread.
The results obtained are as follows :
(1) The strength of waxed thread lowered significantly after sewing and laundering and became nearly equal with that of untreated thread after 20 times of laundering.
(2) The configurations of the load-elongation diagrams of waxed and untreated thread differed significantly between them. But they became nearly equal after 10 times of laundering.
(3) The seam strength of the fabrics sewn with waxed thread was greater than that of the fabrics sewn with untreated one. The difference between them, however, could not be found after 2030 times after laundering.
The influence of laundering on the waxed seam strength was smaller than that on the waxed thread strength.

Whether the practical application of the tissue-paper sanitized with Chlorhexidine would cause any dermal effect was studied by observing the redness on the buttocks of 682 newborn babies, who were born in a hospital between August, 1971 and March, 1972.
The redness rate was 37.43% in the group to which diapers with the sanitized tissuepaper napkin on top were applied and 29.55% in the group to which simple diapers were applied : the difference between the two groups was significant only in September. To know the cause, the patch testing of Chlorhexidine was carried out and the temperature and humidity of the hospital nursery and the absorption of the tissue-paper were examined. Those results being put together, no specific dermal effects were found to be caused by Chlorhexidine; our conclusion is that the use of the tissue-paper of poor absorption in a very humid circumstance must be one of the reasons why the significant difference was found.
Whether the tissue-paper sanitized with Chlorhexidine was applied or not, significant correlation was found between the redness rate on the buttocks and the temperature of the room.

The purpose of this study is to categorize the consiousness of husbands concerning their social connection, comparing husbands living in inner-city tall apartments (termed as A-area) with husbands living in the suburbs (termed as B-area). The number of subjects is 295 from the A-area and 148 from the B-area. The survey using a questionnaire was administered from July to September, 1971. A latent structure analysis method adopting three characteristic indices concerning the consciousness of formal and informal social connections was used to analyze the data.
The findings are :
(1) The subjects in both areas can be divided into two groups based on the degree of consciousness of social connection : Sociable and Unsociable.
(2) In the A-area the Sociable keep more company with fellow-workers and personal friends than the Unsociable. In the B-area the Sociable frequently keep company with their relatives and neighbors. This finding seems to indicate that the type of social connection in the A-area is typical of urban informal ones as compared with formal intimate social connection in the B-area.
(3) The Sociable in both areas have generally lower educational background.
(4) This categorization is found to be unapplicable to the wives of the subjects.

Continuing from the last report, a time study was done among 128 married nurses working in six public hospitals in Sendai (exclusive of the ones researched last time) in August, 1972.
In all three types of day-time, semi-night and night-time work, the time spent for living of married nurses was almost the same as the results of the last report. This time analysis was done according to the family life cycle stages. The time spent for house work of the married nurses who have children under support is the longest, so their time for health and free time is shortened. Also when use of time for these nurses was compared with that of the ordinary working wives according to the working days and days off, it was found that the nurses' working hours in the day-time shift were one and half hours longer than the ordinary working wives'. No difference was noticed among the time spent for house work of the two. However, a great difference of two hours was found in free time. On the days off, both nurses' and ordinary working wives' time spent for health, house work and free time gets longer. But nurses spend a longer time for house work, and their free time is shorter than the ordinary working wives. Almost no change in labor conditions were found in this research than those of 1970, and no signs of improvement were evident.

This report shows time spent by nurses for daily activities according to types of day-time, semi-night, night-time work and also according to family type.
The results are as follows.
1. Nurses' time spent for house work under the day-time shift is similar to the ordinary working wives.
2. In the case of semi-night work, the cleaning of rooms and the family washing are done in the morning, shopping and preparing for supper are done by four o'clock in the afternoon.
3. After night-time work is over, recovery from fatigue by taking a nap is the first thing done in the morning, followed by house work. Time spared for taking a nap is longer in the nuclear family than in the extended.
4. On the day off, time used for house work is more divergent than in the semi-night work schedule, though cleaning must be done in the morning and shopping in the afternoon. The use of time is closer to that of the ordinary house wife.

We have made the same inquiry as Report I for parents and teachers, considering their academic career and occupation. The results are as follows.
1. Regardless of their academic career and occupation, more than ninety percent of the subjects insist on the future need of home economics education.
2. Subjects of every academic career and occupation have expressed their expectations toward home economics education of elementary, middle and high schools as follows : the acquirement of techniques such as cooking and sewing in the home, the cultivation of practical abilities and positive attitudes toward improvement of home life, constructive interest in the relation between society and home, the cultivation of good manners in daily life, and attainment of democratic family relationships.
3. Teachers in particular are greatly concerned not only with the learning of techniques, but also on democratic family relationships, consumer education and the cultivation of creative skills in home life.

The aim of the studies is to submit the information about home economics education related with the UNESCO Survey, in order to improve Japanese home economics education. The questionnaires were sent in May in 1968, to the national universities having department of education or home economics. In part 1, the responses to the items concerning curriculum development are analysed and compared with the results of the UNESCO Survey. The subjects are teachers of universities and teachers of primary and junior high schools affiliated to universities, who are engaged in home economics education.
The results are as follows.
The teachers' regard for home economics education at present is higher than that shown in the UNESCO report, but as to the future view of home economics is reversed.
They maintain objectives which improve human development and family life rather than material living conditions, which seems to make a contrast with the results of the UNESCO report.
They support the participation of boys as well as girls in home economics, not only at primary schools but also at junior and senior high schools.
University teachers consider home economics education more important than the teachers of primary and junior high schools.
