To obtain the relation between the textures of boiled rice and the gustatory characteristics, the author tried a numerical analysis of skin or muscle senses in the mouth during eating boiled rice. For this purpose, the stress-strain curves of boiled rice and the grain were investigated.
Judging from the large deformation of the stress-strain curves under 0-2kg loads, it is seen that each rice species has a proper compression state. This characteristic state was observed in the three parts of rheological field, namely, elastic, plastic, and fracture parts. In general, the material, whose stress-strain curve has a steep gradient at the origin, has stiff, less sticky, and crumbly mouth feel. Consequently the boiled rice prepared with these kinds of rice will not taste good.
It was clearly indicated that there was the reverse relationship between the fracture load and the tastiness ; the less the load, the more tasty. Also the load necessary for the perfect fracture of rice grain appear to correspond with the mouth feel in masticating by molar teeth.

It was observed that pectin was broken down in hot solution rapidly at pH 7.1 and slowly at pH 6.3 by transelimination. The reaction was not induced at pH 4.1. Vegetable tissues are kept firm when cooked with vinegar. This is probably due to the stability of vegetable pectin in the acid solution. It is reasonable to assume that the degradation of pectin by the transelimination causes the softening of vegetable tissues cooked at the neutral pH.

Participating in the attempt by IEC (International Electrotechnical Commission) to establish the international standards of domestic washing machine which has been made since 1965, comparison tests were administered to see if the IEC cloths proposed for artificial soiling can be employed in the JIS method.
Three kinds of cloths (IEC, JIS-A and JIS-B) were artificially soiled in accordance with standard specifications and underwent washing tests by Tergotometer. The following results were obtained.
(1) General tendency of washability characteristics of the cloths from both origins is satisfactorily similar.
(2) Washability of the IEC cloths is higher than the JIS cloths.
(3) Range (R) of washability of the former is larger than the latter.
(4) The JIS standard cloth is more heavily soiled than the IEC cloth.
Effects of the size of test load on washability of the cloths were also investigated by JIS standard washing machine.

Six different kinds of diapers on the market, A (Baby-Snap), B (cotton gauze), C (Baby-Dia), D (Nishiki-diaper), E (Nishiki-Tebiron) and F (bleached cotton) were picked out to study on their 1) water absorbency, 2) drying speed and 3) elasticity, which were considered to be important characteristics of diapers. 1) and 3) above were also examined after the diapers were washed 50 times. Some of the findings are as follows.
1) The higher water absorbency, the better as diapers, but the fabric whose water absorbency is high has low drying speed as found in A and F.
2) The higher drying speed, the better, but the fabric whose drying speed is high has low water absorbency as found in B and E.
3) The tensile strength of fabric in both woof and warp directions is usually weakened by washing, but B and E are a little better than others with respect to strength in the woof direction.
4) Values of Diaper E for 1) and 2) above are remarkably different from those of others because E is made of polyvinylchloride. On the basis of this finding the combination of D (highly absorbent) and E (weakly absorbent) is considered reasonable and also comfortable for babies.

The purpose of this study was to collect the basic information, from a hygienic viewpoint on clothing, useful for selecting and wearing the undergarments by measuring the pressure of inside belts and girdles.
The results were :
1) The pressure exerted by the inside belt indicates that when the belt is shorter than the measure round the waist by 3 cm the pressure is not good for the health.
2) The pressure exerted by the girdle which is shorter than the measure round the waist by 5.5 cm exceeds 40g/cm². The wearer cannot feel comfortable.
3) Upon X-ray examination, it was deduced that the fitted girdles would be not only harmless for the health, but also useful in setting the body frame in a good condition.

1) Measurements of 900 school children in Fukushima City were made in July, 1966. The growth of their chest, waist and hip was investigated.
2) Hip growth with age is the largest among these three, next ranks chest, and the growth of waist is slowest. The maximum annual gain is observed with the boys in 7 th-8 th grade and girls in 5 th-6 th grade. Boys surpass girls in waist girth and girls excel in hip girth for all ages. No great difference exists in chest girth.
3) The value of depth/breadth increases gradually with age in chest, and gradually decreases in waist and hip chest thickens, and waist and hip broaden. The difference between waist girth and chest girth and also waist girth and hip girth become large, especially with girls. This, together with the change in the shape of chest, gradually constitutes the obvious sexual distinction.
4) The correlation of waist and hip girths to stature and that to chest girth are rather high (higher in the latter), because the examinees are children of growing ages.

Photoscopic observations were employed in order to supplement the weaknesses of traditional anthropometry. Japanese men's body configurations in silhouettes were discussed, using photographs of front, side and back poses taken on 91 male university students. Silhouettes were also compared with those on female figures by Yanagisawa et al. The results were as follows :
1) Figures 2-1 to 2-4 show the contours of silhouettes of shoulder, breast, back and hip. Each of the silhouettes was classified according to the degree of slope. Even in the same group, individual silhouettes varied remarkably.
2) Mean values and standard deviations of 10 items of slope are given in Table 3.
3) Differences of silhouettes between male and female were significant at 1% level in anterior breast slope, in back slope and in posterior hip slope, respectively.

In the previous papers we studied the ways of dart-making on a straight line. In the present paper, dart-making on a curve is studied. The method of its drawing is given in the figures from Fig. 5.1 to Fig. 5.7.
Figs. 5.1 and 5.2 illustrate, with some examples, that the method of making darts on a straight line is applicable to that on a curve.
Fig. 5.3 shows that there are differences between the displacement of B and G after the development according to the inclination of a dart line to the curve.
Fig. 5.4 shows how to develop a dart on a plane, making direct use of the curve, on which a dart line has been formed.
Figs. 5.5 and 5.6 present the similar way of development when two and three dart lines are made on a curve.
The figures above-mentioned show the method of making darts on a concave curve and Fig. 5.7 shows the instance with a convex curve.

In order to find the most suitable length of the needle for sewing Japanese Kimono, the author investigated with 150 college students the length of thumb and the manner of holding a needle.
Relations, classifying by thumb-length, between the length of needles and sewing efficiency were investigated by evaluating the length sewed in a certain period of time and uniformity of the stitches.
For sewing two pieces of cloth together, which is the most common practice, a needle whose length is 67±2 % of the thumb length was proved to be most suitable.
Minimum time required for the test was also determined by statistical means and thus the test time was reduced to one-fifth of the ordinary test time.

In order to study the harmony between the design of women's dress and individuality of body type, I made a classification of body types based on the neck and the portion around the neck which are influential factors in dress designing.
Two somatometric surveys were made in Nagoya with approximately 300 girl students aged 18 to 21 in 1964 and 1966. Measurements were taken on 11 points which were necessary to judge body types.
Based on height of side neck, shape of shoulders, breadth of shoulders and facial index, body types were classified in three categories.
According to the correlation table, the shape of shoulders and height of side neck were classified in nine types and the frequency of appearance of each type was investigated.

Dresses with the several basic designs of the neck line and collar were made in accordance with the type classification obtained by the somatometric surveys reported in Part 1 of this paper, and were tried on by eight girls chosen from the examinees in the somatometric surveys.
Outlines of judgment through functional tests are as follows.
(1) The small round neck line is not suitable for those who have short neck, high shoulders, broad shoulders and large face. High collars are not suitable for short necks.
(2) A comparatively wide collar harmonizes with the broad face type.
(3) Broad shoulders do not show up too much if shoulder width is divided by V-line cut in neck line and collar.
(4) Laterally broaden neck line and collar well harmonize with round shoulders, but do not with high shoulders and broad shoulders.
(5) When the same wide collar was worn by round shoulder type and high shoulder type girls, differences in collar stand were observed. The collar stand with high shoulders is higher than with the other. Wide collars are not suitable for girls of these types.

This is an attempt made in July 1967 to ascertain the correlation between the degree of companionship and the interaction in the family. School-children in the 6th grade of primary school in Fukushima-city were picked out as the samples. This first report is concerned with their companionship in the family relations.
The results are as follows :
1. The boys' and girls' scores of companionship are different from each other ; the girls' score is higher.
2. The difference between the groups of nuclear family and extended family is not significant.
3. The difference between groups classified by family occupation is significant. Arranged from highest to lowest : white collar workers, self-management enterprisers, blue collar workers and part-time farmers.
4. The difference between two groups of children, one with job-holding mothers and the other with mothers who do not hold jobs, does not seem to exist in each group. Only in rural areas where very many mothers hold jobs, the scores of the two groups are significantly different.

This report is concerned with the degree of contact of the school-children with their families. The degree of companionship of the same school-children was reported in Part 1, and the correlation between the companionship and the interaction will be reported in Part 3.
In this research, it would be considered that individual total scores indicate the contact or interaction of the child in his family.
1. The boys' and girls' scores of contact are different from each other ; the girls' score is higher.
2. The score of the extended family is slightly higher than that of the nuclear family. But the difference is insignificant.
3. The differences between groups classified by the family occupation are significant; to arrange in order, white collar workers, farmers, blue collar workers and self-management enterprisers.
4. The difference between two groups of children, one with job-holding mothers and the other with mothers who do not hold jobs is insignificant. But in the white collar group, the difference between two subgroups classified by mother's job situation is significant.

The time spent by non-working wives and working wives on everyday task in the home was investigated in 1967, and the result was compared with the similar data collected in 1956 and 1961.
As for the husbands, hardly any difference has been noticed among the data on weekdays and holidays. However, the investigations in 1961 and 1967 indicate that the husbands of working wives have become slightly cooperative in doing domestic chores, since domestic helpers became scarce.
As for the non-working wives, the hours spent on domestic chores have gradually decreased, while the hours spent on leisure activities have increased. The working wives are so busy on holidays as well as on weekdays that they would seem to ruin their health.

The questionnaire on family budgets obtains the financial state of the year at a given time.
Therefore this questionnaire should contain the items of the irreducible minimum for the diagnosis. The features of the main questionnaire are as follows :
1) Being the fundamental form of questionnaires on family budgets, the questionnaire is : applicable to all households.
2) Living expenditure contains cash expenditure, expenditure in kind and the sum of depreciation.
3) On completion of the investigation, the total cash income must be checked in comparison with the total cash disbursements. And if there is a great difference between them, revision is necessary.
4) This form can also be used as a tabulation of the housekeeping account. Some supplementary questionnaires are administered together with the main one to make correct diagnosis.
