    冷凍魚の鮮度判定を細菌学的に検討してゆく緒として、解凍後の細菌の動向を検した結果、次のことが考えられる。
    1. 低温度下での生残菌は解凍後鮮度の低下に伴って、純培養と同様の Pattern を示して増殖する。その増加は保存温度の高いほど速い。また再度常温にもどした場合の魚肉の腐敗は、最初の菌の汚染 (細菌数) とは無関係に、同一温度下では常に同じ速度で腐敗に至ると思われる。
    2. 生菌数は、初期の段階では VB-N の増加とある程度関連をもちつつ増加してゆくものと思われる。生菌数における初期腐敗推定点は、 VB-N の同点より常に先行する。細菌の生理・代謝過程、菌叢交替現象などより、前報における VB-N の初期腐敗推定点は、 すでに腐敗の進行途上にあるとも推察できるので、今後なおこのことに関して慎重に検討をすすめたい。
    3. 魚肉の生菌数と大腸菌群数は相関関係を示す。 冷凍魚の衛生指標菌として、大腸菌群数を迅速に算定することはきわめて意味あることと考える。
    4. 氷衣 (グレーズ) 中の生菌数と魚体 (表皮) の生菌数・大腸菌群数もそれぞれ相関関係を示す。氷衣中のこれら細菌数を測定する意義は、魚の凍結・陸揚げ・輸送などの二次的汚染を示唆するものと思われる。

    Physical behavior of water in margarine and butter was investigated. By analyzing the adsorption isotherm by means of B. E. T. equation, it was found that there was about 1 to 1.5 per cent (wet basis) of water adsorbed as a monomolecular layer in contact with the fatty phase and the rest of the water was adsorbed forming multi-layers. The former appeared to be more firmly adsorbed than the latter. Dielectric measurements were also carried out to ensure the presence of the different states of water. Dielectric losses in the radiowave region distinguished the difference mentioned above.

    植物組織の葉緑体におけるクロロフィルータンパク質複合体の安定性を知るためにクロロフィルaと卵アルブミソよりなるクロロフィルータンパク質のモデル系について加熱、酸、光、遷移金属 (Fe2+ 、 Fe3+) の影響を検討し次の結果を得た。
    1. クロロフィルは温度 (60℃) 、酸 (クエン酸、塩酸緩衝液、 pH5.0) によりかなり分解をうけやすい。またいちじるしく光分解をうけるが、クロロフィルータンパク質系のクロロフィルは比較的安定性を示す。
    2. クロロフィルは遷移金属 Fe2+ (10 -3M) 、 Fe3+ (10-3M) により分解されやすく、とくに Fe3+ によりいちじるしい接触酸化をうけるが、クロロフィルータンパク質系のクロロフィルは遷移金属 Fe2+ およびFe肝に対していちじるしい安定性を示す。
    3. 本実験結果より植物組織葉緑体におけるクロロフイルータンパク質複合体は、温度、酸、遷移金属などに対して比較的安定性をもつものと推考する。

    (1) 円管内に固定した布地の布地平面に対し垂直方向の水透過について、 実験式 ΔP=A+Bv+Cv2 をもとに検討した。
    (2) 流速増加、 布地重ね合わせ枚数増加により透過圧力差が上昇し、 透過は不利になる。
    (3) 水の昇温は透過を有利にする。
    (4) サラン布、 ポリエステル布では流動時間経過により著しい圧力差上昇が認められた。

    It is usual technique in dress making to make agreement between the warp direction of fabric and the lengthwise direction of the clothes. In these days, however, this agreement is not maintained very often because of special designs of clothes.
    In the present paper, the authors have studied the effect of the anisotropic tensile properties of fabrics on transformation of clothes during making and wearing.
    In an effort to find out how the tensile, shearing and bending transformation is made, slacks and skirts for the standard body form were sewed using the material vertically, horizontally, and diagonally. The extent of the transformation produced on the clothes during wearing was measured.
    Through the experiments, the authors have found out that there is no significant difference in the magnitude of the transformation during wearing between warp and weft directions, but the transformation in bias direction is significantly larger than the above two directions.
    It is apparent that the anisotropic tensile properties of fabrics affect the transformation of the fabrics during making and wearing, and have close relation to how one feels in the clothes.

    When clothing materials are used vertically, horizontally, or diagonally, transformation induced in the clothes differs from each other and it affects fitness and comfortableness of the clothes, stabilization of measurements, and feeling of oppression. It is supposed that these relationships are established by anisotropic mechanical properties of the clothing materials.
    In this paper, the anisotropic tensile, bending, and shearing properties of clothing materials are measured and the results are connected with transformation of skirt and slacks which was shown in the previous paper.
    It was found that transformation of the clothes had a relation to the anisotropic tensile, shearing, and bending properties of the clothing materials ; especially yarn and fabric structure of the clothing materials and the anisotropic tensile property had an effect on transformation of the clothes.

    The appearance of the lapel of the tailored collar is affected by the direction of the padding stitches, the physical performances of both outer material and interlining, and especially by the bending rigidity of them.
    The authors have studied the combined effects of the padding stitch direction, the fabric, and the interlining on the mechanical properties of lapel.
    The results obtained are as follows :
    1. The direction of the padding stitches should be in agreement with the lapel line.
    2. Strips diagonally cut out of outer materials and interlinings were pulled in the direction of their length and Poisson's ratio was determined concerning the warp and weft directions.
    The value is somewhere between 0 and 1.
    3. The bending rigidity of the interlining is generally larger than that of the outer material. The combined bending effect of the outer material and interlining is larger than the algebraic sum of the effects of both materials.

    In the previous report the authors studied the anisotropic tensile and bending properties of the outer material and interlining of lapel. In the present paper the authors have studied the effect of padding stitches on the constancy of the dimension of the lapel and found the increase of the thickness, the contraction of the width, the elongation of the length, and the change in the bending modulus, of the combined material sewed by padding stitches. The padding stitches were sewed by hand and by machine. The machine-made stitches were blind stitches and zigzag sewing.
    The results obtained are as follows :
    1. The combined material is lengthened or contracted by the padding stitches. Therefore the seam allowance at the lapel line should be appropriately adjusted according to the different kinds of interlining.
    2. The bending modulus of the combined material depends on the padding stitch method.
    3. The significant effect of the padding stitches on the bending modulus of the materials is observed in the case of the machine-sewed padding stitches.

    The author tried to stratify the outlook on the declining years adopting three characteristic indices.
    A questionnaire was administered to the old folks at home of primary, junior high and senior high school pupils in and around Osaka City.
    The collected data was examined by the method of the latent structure analysis.
    The following results were obtained :
    1. The outlook on their own declining years was divided into two classes-traditional and progressive.
    2. It was verified that the above two-class model construction was applicable to each sampling object.
    3. It was discovered that the probability of finding elderly persons who do not have higher educational background, earn a limited income, and have occupation in the area or organization which does not employ the age-limit system is much higher in the first class than in the second class.
