Sequential changes of ascorbic acid (AsA) content were studied on the strawberry stored in refrigerator and freezing box, and at room temperature.
1) The fresh fruits kept of room temperature (1824°C) began to rot after 5 days, but the change of AsA content was not significant comparing with the degree of their decomposition.
2) The strawberries stored in refrigerator began to rot after about 15 days and showed exactly the same change of AsA content as those kept in room temperature.
3) In freezing box no notable change of AsA content was observed during the first month, but after half a year storage AsA content decreased to one tenth of the initial stage.
According to the histochemical observation AsA retained mainly in the cells around the vascular bundle in every case.

In purpose to get the characteristics of babies' body proportion, the authors calculated 16 indices based on stature, chest circumference and body weight of 1, 316 babies. The subjects are the same as Part 1 of this report, aged from 1 to 12 months. The data were analysed cross-sectionally and the following results are found.
1) At the first month, in both sexes, they have relatively short lower extremity, slim hip and thick neck. At the second month, their abdomen is remarkedly swelling. Relatively wide shoulders and hips and large chest circumference are observed at 5th month. At 12th month, the chest-head circumference index comes to the maximum value.
2) Male babies exceed female babies in relative foot length, intermembral index and Kaup index. On the contrary, females exceed males in acromio-hip index and in chest-thigh circumference index.

In order to determine trace amount of fluorescent brightening agent (FBA) in dilute detergent solution which contains FBA of bis-Stilbene series, the method to concentrate and determine FBA, using cellulose powder as an adsorbent, were investigated.
With the application of this method to dilute built-detergent solution which contains Uvitex 3257, the following results were obtained;
(1) The higher the dyebath temperature when FBA was adsorbed, the more the recovery % of the FBA in the bath.
(2) The greater the amount of sodium chloride as a promoter in the solution, the more the amount of FBA adsorbed.
(3) Under the dyebath temperature of 97±3°C and with the application of sodium chloride 10% o. w. f. as a promoter, it was found that nearly quantitative recovery of the FBA was obtained after successive (1 to 3 times) adsorption treatment for the solution which contains trace amount of FBA.

This paper describes the relation between the moisture affinity of fibers and the porosity of wads by testing the permeabilities of air and water vapor through wads with synthetic fiber and cotton wads which are sold in the market. From the experiments with specimens of 5 cm in thickness having a porosity of 91-99%, the following results are obtained. (1) The correlation coefficient between the permeabilities of air and water vapor through specimens is more than 0.9. (2) When both the thickness and the porosity of cotton wads are equal to those of wads with synthetic fiber, the permeability of air of the former is remarkably smaller than that of the latter. Accordingly, the permeability of water vapor of the former is smaller than that of the latter.

Properties of cotton fabrics for the standard artificial soiling recommended by J. O. C. S. are different from lot to lot owing to the finishing conditions. In this connection, correlation of the change in chemical nature, which were measured by the Methylene Blue Method and Copper Number Method, of the fabrics during oxidative bleaching to the soiling and desoiling properties were investigated.
A linear relationship was found between MB value and copper number in the cotton fabrics treated at 70°C with sodium hypochlolite solutions buffered to give a pH 10.
The more oxidized cellulose were formed, the more the fabric damage, determined by decrease in average polymerization degree (fluidity), tensile and tear strength, increased.
In bleached fabrics, as the carboxyl groups increased, carbon and Fe₂O₃ soils were more easily removed, although Fe₂O₃ were less soilable than carbon soils.

To select skillfully a home machinery, we researched thebest decision rule by our electronic simulation program.
A flowchart of the whole simulation program is shown in Fig. 1. As input items of our program, the number of home machinery's shops, the number of times of the simulation and the various decision rules are read in the electronic computer. After the operation is practiced at the simulate block of the program as in Figs. 26, the following items are put out : the number of the selected home machinery (NN), the arithmetical mean of the values of selected home machinery (AV), the number of times of the best machinery (MAX) and the worst (MIN) selected, the mean of the shops' positions of the selected home machinery (V), etc.
The decision of what is important in the preceding items depends on the objects of selection and thoughts of selector. In this report, however, from the values of AV and MAX in these items, the following results are led. (see Tables 25)
1. In the case that only the best home machinery is searched, the best rule is ((00011111)) (by MAX) or ((00001111)) (by AV). Then, AV=6.146.20, MAX=54.256.8%.
2. In the case that the second one may be accepted, the best rule is ((00011112)). Then, AV=6.01, MAX=57.4%.
3. In the case that even the third may be accepted, the best rule is ((00011113)). Then, AV=5.92, MAX=56.7%.
4. In the case that one need be selected, the best rule is ((00111238)). Then, AV=5.44, MAX=52.4%.

We measured variation and distribution of temperature of the baking sheets in the three types of oven- “A” type (a small semi-direct heating oven), “B”. type (a middle semi-direct heating oven), and “C” type (a direct heating oven) and baked pound-cakes in each type of the gas-ovens.
The results are as follows :
(1) The temperature rises most rapidly in “C” type, “A” type is next and “B” type is third.
(2) In “A” type, the temperature of the baking sheets is lower in the front part and the temperature of the middle rack is nearly equal to that in the oven.
In “B” type, the temperature of the baking sheets is higher in the front part and the temperature in middle rack is about 10°C lower than of the oven.
In “C” type, the temperature of the center of the baking sheets is the lowest and the temperature in the middle rack is about 50°C lower than that of the oven.
(3) In “A” type, the temperature of the baking sheets is the highest in the lower rack and shows a tendency to be low in the lower rack of “B” type. There is great difference of temperatures between the upper, the middle and the lower racks. The temperature was the highest in the upper rack.
Since the temperature of the baking sheets has much influence on the quality of what is cooked, it is advisable to measure the temperature of oven at the nearest point of the baking sheets.

The author has already investigated the home management abilities of wives in various occupations. In this paper, in order to discover what relations exist between home management abilities and school careers of the wives, the author sampled 385 wives out of the former investigation, and examined them.
The results were as follows :
1) Generally speaking, the higher the wives' school careers, the better their home management abilities.
2) Even if the school careers differ, the profiles of home management of the wives closely resemble each other.
3) Among the actions of home management, planning is affected by the school careers, but controlling is not.
4) As for the use of resources in home management, the employment of household appliances and community facilities are affected by the school careers.
5) Home management abilities of wives in farmers, shopkeepers and wage-earners are affected by their school careers, but those of husband-wife working together households are not.

In teaching the skill of home life in elementary schools, pupils' mental development and finger skillfulness must be considered.
In order to find out the most proper age to teach the sewing skill, the author first analyzed the kymographic curve of the movement of the fingers of ordinary female adults and those of the sight-handicapped, and after studying some other date, examined the objectivity of the evaluation. The studied data are as follows :
1. Of the time required, the frequency and the rhythm of the motion of the fingers in the “Naminui” sewing (the most simple and basic sewing) on the kymographic curve.
2. Of the swerving degree from the base line, the length of a stitch and the number of stitches seen in the works finished.
As the result of this study, a considerable correlation was found between the evaluation by these objective data and that by several “experienced” teachers by numerical rating scale method.

1. Family persons investigated.
1) The size of a family decreased in the three regions : Hiroshima, Tokyo and Iwate.
2) The age-range mainly engaged in home-sewing moved from the older to the younger only in Hiroshima region. The ratio of persons employed to those not employed decreased.
3) Concerning the means of achieving sewing-techniques, there was a decrease in the group “being taught by family members”, and an increase in “taking courses at school” and “studying at private sewing schools”.
2) Annually home-made clothes per month.
1) Both western-style garments and baby clothes were made as a whole in the same season of the year in all three regions, there being a considerable change in slacks.
2) Japanese-style garments showed less differences among the three regions in 1972 than in 1967.
3) Bed-clothes showed greater differences likewise.

In this paper, home sewing articles made during 1972 were compared with those of 1967.
There is a tendency of the same kinds of articles in garments of western and Japanese style, bed-clothes and minor articles made in the three regions, Hiroshima, Tokyo and Iwate. Differences between findings in 1972 and 1967 are as follows.
(1) Concerning garments of western style, one-piece dress making increased, while that of blouses decreased. Garments made per household decreased a little in Tokyo and Iwate; but increased in Hiroshima.
(2) Garments of Japanese style, bed-clothes and minor articles made per household decreased in all three regions.
(3) Mending was frequently practiced in every region; most frequently in Tokyo.
