家鴨卵黄の乳化性を知る目的をもって、卵黄および卵黄から分離調製したリポタンパク質のエマルジョンの安定実験、さらに卵黄を用いてつくったマヨネーズの官能検査を行ない、併せて鶏卵黄の乳化性と嗜好性を比較検討して次の結果を得た。
1.卵黄・コーンサラダ油・水よりなるエマルジョンの分離率は家鴨卵黄、鶏卵黄ともに新鮮卵が貯蔵卵より小さい。貯蔵卵のエマルジョンの分離率は1日目貯蔵卵においては両者の間に大差はみとめられないが、10日目貯蔵卵においては家鴨卵の分離率が小さい。
2.卵黄・水よりなるエマルジョンの分離速度は室温20℃においては貯蔵初期15分問において、もっともいちじるしい。家鴨卵黄は鶏卵黄よりエマルジョンは安定で、とくに家鴨卵の1日目および10日目貯蔵卵黄はいちじるしいエマルジョンの安定性がみとめられる。
3.卵黄リポタンパク質・サラダ油・水のエマルジョンおよびリポタソパク質・水よりなるエマルジョンの分離率は家鴨卵黄、鶏卵黄ともに貯蔵の経過にともなって増大するが、家鴨卵黄は鶏卵黄に比して、その分離率は小さい。
4.卵黄のエマルジョンの安定性は、食塩または食酢の添加によって増大し、とくに両者の混合添加はその安定性をいちじるしく増大させる。
5.家鴨卵黄を用いて調製したマヨネーズは、鶏卵黄のものより食味はすぐれているが、色と香りが劣る。しかし、香辛料の添加により、嗜好性を向上させうる。

○ NaCl添加の卵白泡について
(1) NaCl添加の卵白液の泡立ちやすさはその濃度に殆んど影響されない。そしてその比重は無添加の泡の比重とほぼ同程度である。
(2) 泡の安定性は<0.1molの低濃度では比較的安定で0.3～1.5molの中濃度で安定が悪くなり、>2.0molの高濃度で再び安定は増し、無添加の泡よりはるかに戻り液が少ない。
(3) 卵白液の表面張力はNaClの濃度に比例してごく僅かずつ増加する。
(4) 表面張力と泡の比重の関係はこの程度の表面張力えなの差は脛すなわち泡立ちやすさに殆んど影響を与い。
(5) 表面張力は泡の安定性に大きな影響を与えない。
○ その他の塩添加の卵白泡について
K₂SO₄、KCl、KNO₃、KIの4種の塩を添加した卵白泡については
(1) 塩の種類別比重はK₂SO₄添加の泡がやや小さく、KCl、KNO₃、KI添加の泡がやや大きい。
(2) 塩の濃度は各塩とも比重すなわち泡立ちやすさに大きな影響を与えない。
(3) 泡の安定性は食塩添加の場合と同様で<0.1molの低濃度では埠較的安定で、0.5～2.0molの中漢度では安定性悪く、>3.0molの高濃度では著しく安定性を増す。これらのことは泡の安定性に蛋白の水和が大きく影響することを示すものである。
(4) 塩の種類別安定性は K₂SO₄>KCl>KNO₃>KIで、これは無機イオンの水和力と一致する。すなわち、Hofmeister順列が認められる。
以上のことは安定な卵白泡を作るためには蛋白の水和を下げ、保護膜の生成が容易になるような条件下で泡立てる必要があるという考を裏付けるものである。

The preceding report (Part 1) was made on sautéed uncooked rice. The present paper gives a report on the experiments of sautéing cooked rice. The result was compared with that of the preceding report. The following facts were observed.
(1) The lower the temperature of cooked rice, the easier sautéing at the beginning, but cooked rice of lower temperature requires longer time to reach the serving temperature, and sautéing becomes difficult as rice increases stickiness with time.
(2) When the cooked rice is warm enough, it reaches more quickly to the serving temperature, but sautéing is not as easy as with colder cooked rice. If the amount of butter is increased, this difficulty can be avoided.
(3) The appropriate amount of butter seems to be from 10 to 20% of the weight of rice.
(4) The differences of property between sautéed cooked rice and cooked rice fixed with sauteed uncooked rice were shown clearly in the taste testing, rate of dehydration, Farinogram, amount of fatty substance absorbed into the rice surface, the microscopic observation, and the diffraction pattern of X-ray.

Correlation between foaming ability and detergency of the solution composed of saponin and surfactant has been studied. Three kinds of saponin were investigated. Surface tension and viscosity of the solution have also been measured.
Experimental results are summarized follows :
(1) Three kinds of saponin have apparently different values in surface tension, viscosity and especially in foaming ability.
(2) The aqueous solution of saponin has slightly higher detergency than water at 40°C.
(3) The saponin-surfactant mixed solution decreases detergent quality as saponin concentration increases. In this respect, saponin is not suitable for detergent component.
(4) Addition of a trace of polar oleic acid to the nonionic surfactant improves detergency and foaming ability, whereas addition of non-polar liquid paraffin is not effective.

Permachem (organic tin compounds) sanitized socks demonstrated strong anti-fungal and antibacterial activities, especially against fungi such as Trichophyton mentagrophytes and Gram-positive cocci such as Staphylococcus aureus, but they were ineffective against Gram-negative bacilli such as Escherichia coli.
The anti-fungal activities against Trichophyton mentagrophytes were not enervated even by 100 washings so far as synthetic detergents were used.
These results lead to the following conclusion : Sanitizing socks with Permachem is very effective measure to prevent Trichophyton infection or so-called “athlete's foot”.

For the purpose of clarifying the relation between the silhouette formed by gathering and the physical properties of the cloth, the experiments were carried out from the standpoint of clothing construction, using 1/2 size models of actual gather-skirts and other simplified models.
As the results it has been found that the physical properties such as stiffness, thickness, crease-resistivity, modulus of elasticity and weight of the cloth seem to have influence on the shape of skirts, and stiffness is most influential among them.

This paper intends to collect some basic data on the body for designing the desirable clothing.
(1) With both sexes from four years of age to thirteen years of age the measurement of each part increases gradually as they grow. There are clearly significant differences between all adjoining age groups. Children at ages from four through thirteen show that they are in the very period of growth.
(2) Differences between sexes are as follows. Boys surpass girls in measurements of all parts after thirteen years of age. Girls show characteristic features of adolescence around the age of eleven and surpass boys in measurements of all parts around these years of age. These sexual differences are significant.
(3) The correlation ratio of each item to stature is very high. Each ratio of five items to stature is larger than 0.7 except posterior waist length. Highest of all, the ratio of posterior full length to stature is about 0.9.

From the viewpoint of clothing construction, we measured 16 items of body parts with 498 samples in the period from 1963 to 1967. The subjects are freshman college girls (the average age 18 Years and 11 months).
The results :
(1) There are no essential differences in the body types among the results obtained in each year.
(2) There are no essential differences between rural subjects and urban subjects in the lengths of the body parts, but there are significant differences in the girths. The rural subjects are superior to the urban subjects in wrist girth (significant at less than 1% level), hip girth, neck base girth, armscye girth and posterior shoulder width (equally 5% level).
(3) The girth values obtained by the present investigation are superior to those obtained by the nationwide investigation on college girls, and the length values in the former investigation are inferior to the latter.

In order to obtain measurements of clothing for obese children from the viewpoint of clothing construction, we studied the character of obese children's somatotype in comparison with normal children's.
This study consisted of 11 body part measurements of 402 boys and 540 girls aged from 7 to 18 (measured in 1966 and 1967). The measured items were stature, back shoulder width, bust girth, waist girth, hip girth, neck base girth, upper arm girth, upper thigh girth, weight, skinfold of upper arm and skinfold of back.
The results are as follows :
(1) Obese children are remarkably superior to normal children in weight, skinfold and girth measurements-bust girth, waist girth, hip girth, upper arm girth and upper thigh girth.
(2) Comparing with girth measurements of the trunk of obese children, their back shoulder width and neck base girth are relatively small.

(1) Many companies have come to adopt uniforms for their women employees since the end of the war. This motivated our investigation on the actual state of those uniforms and conditions of the ideal one.
(2) This investigation was performed during July through September, 1968, at ten companies in Mie, Gifu and Aichi Prefectures, who employed comparatively many women workers.
(3) The results of this investigation showed that the female workers' concern in their uniform was high. Due consideration ought to be given to its comfortableness, neatness and up-to-dateness as well as to the movableness in it so that the women's demand will be satisfied. To our regret, however, we cannot say that the companies we inspected were giving sufficient consideration to these points.

Object : In what way should the slanting shoulder-sleeve line of Kimono-sleeve, its length and width be decided ? (The term “Kimono-sleeve” is defined here as the non-cut sleeves in general including so-called Kimono-sleeve, French-sleeve, Dolman-sleeve, etc.) There have been no fundamental rules for calculating them except those obtained by experiences. The object of this paper is to find out a applicable rule to the relationship between the shoulder-sleeve line, sleeve length and width from the viewpoint of practical use and beauty.
Method : First the shoulder breadth, front bust breadth, back breadth at the breast height and shoulder-joint girth were measured together with the change in their values in accordance with body movement.
Next, based on the measurements, drafts were made with various sleeve angles (angle between the slanting sleeve line and the horizontal line).
Lastly, samples with each sleeve angle were made, and tried on the human body under moving conditions.
Result : It was made clear that the sleeve angle should be between. 18° and 45° in order that the sleeves satisfied necessaried conditions of comfort, practicality and beauty.

Tamugimata, Asahi-mura, Higashi-tagawa-gun, Yamagata-ken, is a hamlet with three- or four- storied thatched houses clustering on the western slope of Mt. Gassan. The trait in the structure of these houses had been attracting attention and surveys were made by the author in 1959 and 1960, the report of which was printed in The Journal of Home Economics of japan, 12 (1961).
Recently these houses have been transfigured considerably and further investigations were carried out in August, 1966, and July, 1968, by means of field surveys and interviews.
Through these investigations it was learned that about sixty per cent of thatched multi-storied houses were completely rebuilt or partly remodeled by 1960. The partial remodeling which was made together with the roof transfiguration was found mainly in kitchen, bathroom and lavatory, and also changes were carried out to make bedrooms upstairs.
The houses have been remarkably improved, but there are still many problems to be studied in connection with workshops, drawing rooms, halls, and preventive construction against the damage by snowfalls.
The transformation of the houses has been made mainly because the preservation of miscanthusthatched roof is difficult. But it seems that the change is also due to short durability of wooden buildings, and new modes of living in the village derived by the improved rice cultivation and increased cash income from the sale of pholiota nameko.

As we reported earlier in the Journal of Home Economics, 19, 228 (1968), we made a study of the parents having delinquents of junior high school ages in comparison with the parents who had no delinquent children. Our study revealed that among ten types of undesirable parents “parents in discord” are found far more often with problem children than with wholesome children. This shows that the harmonic cooperation between parents is of vital importance in the formation of young people's character. This also leads us to believe that parental cooperation has decidedly an important effect upon the mental development of children and also their scholastic achievement. Diagnosis tests on children's life-environment were administered in six elementary schools in order to find out the relationship between the children's intellectual abilities or their scholastic achievement and their parents' marital adjustment.
The following coefficients of correlation were obtained.
(1) Between intelligence deviation value and scholastic attainments : 0.72
(2) Between intelligence deviation value and harmonic parental cooperation : 0.78
(3) Between harmonic parental cooperation and children's scholastic achievements : 0.56
These figures positively indicate the existence of correlation and the importance of close partnership between parents in bringing up chidren.

A large proportion of the families with working wives have no children. Also in a large percentage of cases working women's families with children live with either wives' or husbands' mothers. This fact indicates that it is difficult for wives to work out without the cooperation of their families, especially of their mothers. On the other hand, many wives who hold jobs send their children to nursery schools. To send them to nursery schools has been made easier these days owing to the recent increase of nursery schools, but there are still many complaints about them especially insufficiency in number, lack of baby nurseries and shortage of available hours.
The “white collar” married women's chief motive for resigning from their positions is their husbands' transference to remote places.
