To investigate the effects of fruits juice on the properties of gelatin gel, some basic experiments were performed by gelatin gel which was added organic acids, or the mixtures of organic acids, sugar and/or pectin. The properties of fruits juice jelly were also studied.
(1) When organic acids (citric acid, succinic acid etc.) of the same normality were added to gelatin sol, pH concentration of solution was different in each acid. Consequently, the differences were observed on the properties of gelatin gel.
(2) The gelation of acidified gelatin sol was accelerated by addition of sugar and repressed by pectin. However, when sugar and pectin were added together, it was gelatinized easily, and the gel was stiff and more difficult to dissolve if compared with the gel which sugar alone was added.
(3) Among the gelatin gel containing fruits juice of the same acidity, the grape jelly which contains sugar and alcohol precipitable matter such as pectin was gelatinized easily. On the contrary, strawberry jelly was found to be hard to gelatinize.

To investigate the effect of iron pan used for frying on the deterioration of oil, the amount of iron dissolved into oil from iron pan was determined after frying wet cotton seats. Furthermore, the changes of iron content and specific numbers of oil containing test pieces of carbon steel were determined during this frying and also the frying of several kinds of food in pyrex glass beaker.
(1) When rusty iron pan was employed as frying apparatus, considerable amounts of iron dissolved into frying oil from this pan, while little amount of iron dissolved out from pan which had been used for a long time.
(2) When oil containing test pieces of iron plate was used for the frying of wet cotton seats in glass beaker, color, viscosity and acid and TBA values of oil were increased following the heating time and oil was deteriorated remarkedly. The content of iron in oil during frying decreased first and then increased. By this the properties of oil was not affected so much.
When foods were fried instead of wet cotton seats with the same system, changes of the content of iron and the properties of oil were not so large. This phenomenon was assumed to be due to the absorption of the dissolved iron with food and by this the properties of oil was not affected so much.

Changes in textures of cooked noodles with cooking times were studied by the mensurations of three characteristics using a texturometer, already reported.
Measurements of parameters at one point clearance using a texturometer were not always useful to express texture differences of cooked noodles made from various flours. Mensurations of three characteristics about hardness and cohesiveness of cooked noodles, however, were fairly useful to express those texture differences. These three characteristics represented the characters of whole texture, texture of interior layer, texture of exterior layer of cooked noodles.
Meanings of each characteristic satisfactory coincided with the relations between cooking conditions and textures of cooked noodles. Also the relations between each characteristic and cooking condition would be helpful to elucidate texture differences of cooked noodles made from various flours.
Moreover it would be possible to estimate optimum cooking conditions of cooked noodles, by using the relations between each characteristic (about hardness and cohesiveness) and cooking time.

Effects of the concentration of a sequestering agent, sodium tripolyphosphate (STP) and sodium hydroxide in presense of 0.2% sodium dodecyl sulphate (NaDS) were studied with regard to the soil removal efficiency of stearic acid from cotton and polyester fabrics in hard water.
It was found that the addition of sodium hydroxide as a builder made soil removal much easier with spontaneous emulsification brought about by the soap formation at the soil-liquor interface. However, in case of STP, the extent of saponification was not strong enough to exhibit ancillary effects. Moreover, in the concentration ranges of STP higher than its stoichiometric sequesteration ratio to calcium ion present in hard water, the presense of STP even decreased the soil removal owing to its negative effects, like other simple electrolytes, on emulsification as well as on solubilization.

The stiffness of fabrics laminated with non-woven interlining was investigated by using heart-loop method in order to examine its dependence on the orientation of resin adhesive on the interlining. Three kinds of cotton gabardines which differ in their thickness were used as samples. The interlining which has resin spots distributed in a pattern of closest packing was bonded to the fabrics so that line of resin spots may be parallel (G_B-1) or perpendicular (G_B-2) to the direction of warp in texture.
It was found that the stiffness of (G_B-2) samples reflects well that of respective fabrics in comparison with that of corresponding (G_B-1) samples. This result was interpreted well by that the (G_B-2) samples have more concentrated spots of bonding with the thread crossing in fabrics than (G_B-1) samples because of parallel orientation of resin spot to fabrics.

Long ago the clothing worn by the Ainu race were kera, kap-ur, rap-ur and chep-ur-those of plant, animal skin, bird skin, and fish skin-and since they could get cotton and silk by barter toward the later Edo Era, they came to wear attushi, letarupe, chikar-karpe, ruunpe, kaparamipp, chigiri and mour.
I studied how they put them on, consulting the field surveys based on the evidence by the old there. In this first report I wrote of the quantity and the way of their clothing.
Their fine garment was usually made by a wife with her greatest effort and affection for her husband as a choice present to him, and he did not own so many as the Japanese today. But they had many ways of wearing; for the ceremony, for daily use, and for laboring. What is more, in another district they wore in another way-for instance, some of them used a girdle on the garment as in the case of kimono and others put the garment over their shoulders like haori. As well as the clothing for the adult, there were those for babies and children and for the dead with their own ways and rules.

For the purpose of planning babies' head-gears, the authors measured 554 babies' heads (350 males and 249 females) aged 1 to 12 months by the tape measure in 1973. The items of measurement included head girth, right tragion-under mandibula-left tragion length, right tragion-protuberantia occipitalis externa-left tragion length, right tragion-vertex-left tragion length, and protuberantia occipitalis externa-vertex-glabella length.
The following results were obtained.
1) Though all measurements increase rapidly especially before 3 or 4 months, the growth rate of each measurement is different. The occipital and parietal regions grow relatively earlier than the temporal, frontal and mandibular regions.
2) Taking the head girth as basic item, 5 sizes of babies' head-gears (S : 38cm, SM : 41cm, M : 44cm, ML : 47cm, L : 50cm) were established and the sizes of other 4 items were estimated by the correlation coefficients between the head girth and them.

In her paper the writer touches upon the characteristics of the pair of trousers under consideration in reference to the technique used in the present example, by pointing out that the said costume was known to the contemporaries by the Japanese name “tattsuke”.
She examines the details of the present item from the point of view of the history of the Western costume, as she judges that the present example bears evidences of the influence of this type of Western costume that may have worked upon it.

Detergent effect of sea water at household washing with non-ionic surfactant and anionic surfactant (LAS, SDS) has been investigated. Detergent efficiencies evaluated by both artificially soiled cloths and naturally soiled cloths under the test conditions have shown a good correlation and the possibility of applying sea water partly in place of tap water was confirmed. Main results are summerized as follows :
(1) For non-ionic surfactant, sea water exhibited detergency as good as deionized water.
(2) For SDS, sea water was more effective than deionized water.
(3) For LAS, a warer mixture composed of 80% deionized water and 20% sea water was, with regard to detergency, more effective than the deionized water alone.
(4) For built detergent (LAS 19%, Na₅P₃O₁₀ 25%, Na₂SO₄ 40%, Na-silicate CMC 1%, H₂O balance), sea water was slightly inferior to 5°DH water, but this built detergent seemed applicable to practical washing.

The authors have studied the growth of infants in order to plan infants' clothes. In this report, the relative growth of each part of the body to stature and chest girth is investigated with the allometry equation y=bx^α in which stature or chest girth is taken as x and other items as y. The materials were collected cross-sectionally from the babies aged 1 to 12 months in 1973.
The results are summarized as follows.
1) As for the relative growth to stature, upper and lower extremity length in both sexes and biacromial width in female show monophasic. The items which show diphasic are weight, foot length in both sexes and biacromial width in male. Maximum hip width in both sexes is triphasic. The period of phase shifting, that is, the critical point of each item is observed at 3-4 months when stature is 61-64 cm.
2) As for the relative growth to chest girth, abdominal girth in male is monophasic. That of female shows diphasic and critical point is observed at 1-2 months when chest girth is about 40 cm. Hip girth in both sexes is diphasic and at 3 months the critical point is observed when chest girth is about 43 cm.

(1) Kinds of furniture mostly found in their rooms are desks (94%), bookcases (73%), and chest of drawers (63%). There are chairs and beds in less percentage. Ten to fifty per cent of the area of the room is occupied by the furniture.
(2) Colors used for the interior decoration are yellow tone for curtains, brown or cream for walls, and red or green for the carpet. As a whole, there are tones of warm colors in their rooms showing that youths prefer to have cheerful colors.
(3) The result of the S.D. system investigation on young men's and women's images of the rooms of their own is as follows : Junior high-school pupils have the idea that their rooms should be 'intimate, ' 'composed, ' 'bright, ' and 'fresh looking.' Senior high-school pupils think their rooms as an 'intimate' place. University students deem their own rooms are 'quiet' and 'composed' space. This result does not show their individuality, their fondness to spend in solitude, nor their positive attitude toward making particular effort to build up their own rooms in compliance with their taste of purposes.

This report was based upon the results of the 1973-74 survey which was made on the transfiguration of the forty-six houses of the families who had settled in Shin-Yamadera, Oishida-machi, Yamagata Prefecture, in 1946-48.
Almost all the houses built at the time of settlement were remodelled or newly constructed from that time, in consequence of higher productivity. But the old-fashioned idea of attaching too much importance to the interior decoration of the drawing-room and of neglecting to improve the imperfectly-equipped bath-room or lavatory was at a very low standard, compared with the idea of houses held by other farm villagers so far surveyed.
The age structure, family make-up, and plots were characteristic of the settling area, but a great influence of the previous living conditions of the settlers was found even at the new start in their lives.
