比較的熟成期間の長い梅酒と短い梅酒について一般分析、糖の定量、色調、及び有機酸の分別定量を試みた。
1. 有機酸は揮発酸は少なく、ほとんどが不揮発酸であった。
2. 熟成期間の長いものほど加えた蔗糖の転化がすすみ、糖の大部分はブドウ糖と果糖であり、他にわずかの蔗糖と未同定の2 つの糖が見出された。
3. 色調は漬け込み2～4 ヵ月で急激に濃くなり、1年後も徐々に濃くなった。
4. シリカゲルカラムを用いたクロマトグラフィによる有機酸の分別定量の結果、酢酸、ギ酸、アコニット酸、シュウ酸、リンゴ酸、クエン酸及びクエン酸モノエチルの存在を認め、特にリンゴ酸とクエン酸は多量に存在していた。

In the previous paper, it was reported that more thiamine and riboflavin were determined in several kinds of foodstuffs by the extraction with Taka Diastase SS treatment than by the ordinary extraction.
Therefore, in this paper this modified extraction method was applied to 10 kinds of foodstuffs, and it was compared with the ordinary extraction method.
The results are as follows : by the extraction with Taka Diastase SS treatment, the determined thiamine increased by 10-20% in the 10 kinds of foodstuffs and riboflavin 10-40% in 9 kinds of foodstuffs, comparing with the ordinary extraction method.
It was suggested that these increased amounts were resulted from the action of the enzyme. Accordingly, it is concluded that, when thiamine and riboflavin contents in natural foodstuffs are determined, it is necessary to give protease treatment during their extractions in order to set them free from protein in foodstuffs.

1. 実際に供した野草類の総Ca含量は 22～331mg %を示し、そのうち5%塩酸溶出Caは総Caの 12～59 %で葉身部の方に多く含まれていた!
2. 蓚酸含量は、供試試料中おもに食用とする部位を測定した。その結果は522～1519mg%で、わらび、つわぶき、ふきなどの葉柄部に多く含まれていた。
3. ふきの水浸漬実験の結果、僅かではあるが蓚酸が除去された。
4. 野草のあくぬき法として一般に行なわれる水茹で、重曹溶液茹で、炭酸カリ溶液茹でを試みたが、いずれもよく除去した。なお、ふきやよめなは、蓚酸除去の点では、水茹でで十分だった.
5. 胃のモデル実験では、茹で試料総Caの 77～95 %が利用可能との結果を得た。

佐賀市市販のたまねぎ、ねぎ、わけぎ、にんじん及びもやしについてビタミン C 含有量を測定し文献値との異同及び季節による変化を調べた。
(1) たまねぎの総Cの平均は7.83mg%で文献値の78.3%であった。4月の新たまねぎでは最高 21.20mg %を示すが、その後急速に減少して8月には 5mg % 程度となり夏から秋に低く冬にはまたいくらか高くなる。
(2) ねぎの総Cの平均は 27.87mg% で文献値より約11%高かった。これは当地方のねぎは緑色部を多く含むためと思われる。また緑色部は白色部より平均で 32% 程度C量が高かった。出まわり期の10月-3 月における C量の変動は、10月-12月より1月-3月の方が C 量が高かった。
(3) わけぎの総 C の平均は40.19mg%で文献値より33%高く、季節による変動では9月の出はじめに低く、その後急速に増大しその後の変動は少ない。
(4) にんじんの総Cの平均は 6.81mg% で文献値より僅かに低く最高は14.80mg%で最低3.75mg%の約 4 倍となり上下の格差が大であった。季節による変動は少ない。
(5) もやしの総Cの平均は 10.56mg% で文献値の1/3強にすぎず最高でも13.95mg%で最低は4.80mg%であった。
月別変動は少なく法則性は認められない。

1. 電子レンジ加熱の苺ジャムは、本実験の条件では、電熱器加熱のものに対して約1/2の加熱時間で仕上がった。加熱前にさとうによって果汁を浸出させる必要もなく、火力調節の手数もないが、原料の分量に対して、目的の砂糖濃度に仕上げるための加熱時間については、注意を払う必要がある。
2. 電子レンジ加熱によるものは、官能テストの結果、電熱器によるものより好ましいという結果が得られた。
3. 電子レンジ加熱によるものは、香りが良く、色調も美しい。
4. 電子レンジ加熱によるものは、ゼリー化が少ない。しかしレモン汁を添加することにより、両加熱法とも、ゼリー化を高め、両加熱間の差は少なくなる。
5. 電子レンジ加熱によるものは、やや酸性が強い。
6. 電子レンジ加熱によるものは、蔗糖の転化率が少ない。

Test cloths of Nylon (polyamide fabrics), Tetoron (polyester fabrics), Acetate and Cashmilon (polyacrylonitrile fabrics) were sized after washing by immersing them in 0.01%, 0.03% and 0.04% aqueous solutions of PVA, CMC, Dextrin and Chitosan. The effect of the sizing on the betterment of the quality of being easily cleansed and keeping the original stiffness was studied intensively and resistance to soil and creases and air permeability of each test cloth were also investigated.
Main results obtained were as follows :
1. Nylon cloth sized with 0.01% aqueous solution of PVA after washing had nearly the same stiffness as the original stiffness. However, after this sizing the cloth was not; easily cleansed. One-hundredth per cent aqueous solution of CMC was found to be recommended, although this made the cloth a little stiffer.
2. For Tetoron cloth, sizing with 0.01% aqueous solution of CMC was most desirable.
3. For Acetate cloth, sizing with 0.04% aqueous solution of CMC was best.
4. Cashmilon, from the viewpoint of bending resistance or crease resistance, does not need sizing. In order to make the cloth more easily washable by detergent, however, CMC sizing (in 0.01%-0.03% solution) was suitable.
5. Concerning air permeability, PVA sizing was most desirable. CMC sizing made air permeability worse.

Resin-finished rayon fabrics decrease their specific gravity, moisture content and water absorption. On the other hand, they increase their resistance to swelling, shrinking and creasing.
As the number of washing increases, owing to the desorption of the resin anti-shrinkage and anti-crease characteristics were deteriorated, but they were still better than those with the untreated fabrics after many washings.
Better results were obtained as the quantity of the resin increased, although the betterment was not remarkable under conditions employed.

1. There are little or no differences in stature, cervical height and shoulder width between primary school boys in Hokuriku district and other districts, but total and front crotch lengths of the former are longer than the latter.
2. The full length and weight of junior-high school boys in Hokuriku district are about the same as the national average, but the boys are less developed in upper-arm girth, thigh girth and hip girth and more developed in chest girth.
3. Percentage of the junior-high school boy who has inverted triangle physical form increases as the school year advances. The percentages are :
the first year-42 %
the second year-48 %
the third year-60 %

Twelve items of a body which are closely related with the clothes-measurements were investigated on 900 children, from the first year primary school boys and girls to the third year secondary school boys and girls inclusive, in Nara City.
The work has yielded the following results :
1. The mean value of the measurement of each item gradually increases with age. For both boys and girls the greatest increase among length items is obtained with the, whole length and among girth items the hip. The item which shows the least increase is the head girth.
2. The greatest yearly increase in measurements of boys is shown between the first and the second years of secondary school and that of girls between the fifth and the sixth years of primary school, that is one or two years earlier than their menarche.

Somatometric studies on infants aged from 4 to 6 were carried out. From the obtained data, the form of the trunk part of infants was elucidated with the purpose of obtaining the basis of construction of infant clothing. The cross sections were obtained based on each correlation between “width and depth”, “width and girth” and “girth and width-depth index” of the bust, abdomen and hip.
Both bust girth and hip girth were longer than the circumference of an ellipse equivalent of these girths in the width-depth index.
The form of the trunk apparently showed the dependence on sex. Hip girth of sixty-three per cent of female subjects was larger than that of male subjects and also their own bust girth.
Bust width and hip width were equal in fifty per cent of all examined boys, and the width was two centimeter greater than the abdomen width.

The design of dresses should be conceived with close relation to all elements of physical forms of those who wear the dresses. Continuing from last report which dealt with women's neck, I have investigated in the present paper forms of the trunk of women, and tried to classify the forms into several types and studied the frequency of the appearance of each type. The examinees and the conditions of measuring are the same as Part 3 of this series of studies. Twelve items mainly around the trunk part were measured. Moreover, I took photographs of the front and side figures of 271 girl-students who wore a brassiere and a corset by the silhouette machine and measured the angles of shoulders, breast, back and hip on the photographs.
Classification of forms and rate of their appearance :
1. On the basis of the correlative distribution of differences between biacromial breadth and waist breadth and transverse diameter of hip and waist breadth, I classified forms of the trunk into nine types. The rate of appearance of each of these nine types was investigated.
2. Forms of the trunk were also classified by the correlative distribution of angles of the back and the hip.
3. Special forms observed in twelve parts were examined and their appearing rates were calculated.

The puroses of this study are (1) to classify farm families based on the fact that quantity and quality of family labor force vary with the stage of family development (family life cycle), (2) to determine the relationship between the type of family and household income and (3) to find characteristics of way of living of each family type.
The following tendencies are found :
1. Household income and available family labor closely relate to the family type.
2. Labor required for increasing household income is more with the farm families of joint type than of other types.
Families of nuclear type or families of couple are more modernized than other type families in view of the following aspects which feature the way of living :
1. Family tension is weaker.
2. The household tasks are more clearly assigned to each member of the family.
3. Propensity to consumption is higher.
4. Nutritive conditions of the diet are better.
