    This work was carried out to investigate waste water contamination caused by preparing for and doing dishes of two kinds of school lunch, A and B, which are deep fried dish and boiled dish. The study dealt with 1, 825 meals in five days. The average amount of waste water was 13.9 liter/meal, and in this respect there was no difference between A and B lunches. The most abundant water was used between 2 : 00 and 4 : 00 p. m. when dish-washing was done. SS, COD, BOD and TOD in the waste water were measured by standard methods set forth by JIS (K 0102) for the examination of industrial waste water. The results were as follows (range of amount obtained in five days and average value are shown in ppm).
    SS : 6-452, 145; COD : 40-1, 038, 285; BOD : 57-1, 572, 483; TOD : 43-1, 940, 612.
    These data were larger than the permissible value for public waste water. There was a difference in contamination of the waste water between A and B lunches; the respective averages of SS, COD, BOD and TOD for A lunch were larger than those for B. From these results it should be noted that egg, powder and mayonnaise are highly contaminative and much of them are used in A.

    Theoretical considerations were made on the baking method in which dough was fermented at the low temperature, (5°C). The following results were obtained.
    1. Gassing power of the dough was increased when it was recovered to 30°C after preservation at 5°C within 3 days as compared with the control dough without low temperature preservation. However, serious decrease in the gassing power was observed for a dough stocked over 3 days at 5°C.
    2. Increments of extensibility and resistance in doughs preserved at 5°C for 24 hour or 48 hour were observed by extensigraph.
    3. Preservation of the undermixed dough at 5°C within definite time improved loaf volume of the dough. The loaf volume of the undermixed dough did not exceed that of the well-mixed dough except in a few cases.

    α and β globulin of azuki bean were fractionated from crude globulin fraction by salting out with 30% and 85% saturation of ammonium sulfate.
    An examination of the composition of globulin components was performed by gel-filtration chromatography on a Sephadex G-200 column, determination of amino acid composition, N-terminal amino acid analysis and solubility test in aqueous sodium chloride solution.
    β globulin was revealed to be main component of azuki bean protein and appeared homogeneous on gel filtration in 1 M sodium chloride solution. However, on solubility test it was shown heterogeneity and three N-terminal residues were detected.

    It was observed that the viscosity of “Kimizu” decreased when egg yolk was mixed with the starch paste. Experiments were carried out to find out its reasons, and the following results were obtained.
    1) The viscosity of the starch paste decreased remarkably when egg yolk was mixed with the starch paste of 70°C.
    2) By mixing egg yolk, the starch paste which had contained sugar or salt decreased its viscosity, on the other hand that which had contained vinegar increased the viscosity.
    3) In cases where oleic acid or lecithin was added to the starch paste, there was no change in the viscocity of the paste. When α-amylase was added, the viscosity decreased.
    4) Amount of reducing sugar in starch mixed with egg yolk solusion was maximum at 50°C, pH 6.9.
    5) The thin layer chromatogram detected maltose in the starch mixed with egg yolk or α-amylase.
    As a result of these studies, it is supposed that the changes in the viscosity of the starch paste mixed with egg yolk are caused by α-amylase in the egg yolk.

    To examine the ease which is inevitably required in basic sleeve pattern designing, the authors applied gypsum method.
    The bandaged gypsums were obtained from six different postures of an upper limb on which chequers had been drawn by Indian-ink. Being incised appropriately, each gypsum was made nearly flat (developed gypsum). The area of basic sleeve pattern and that of developed gypsums were compared.
    The area of gypsum obtained from the limb with extended shoulder was maximum, while that with contracted elbow was minimum. Although the area of basic sleeve pattern was slightly larger than upper limb skin surface, the limb movement in the basic sleeve was considerably restricted since the forearm surface became larger than the corresponding part of the basic sleeve according to elbow contraction.
    Therefore, it is desirable to measure the arm surfaces of various postures to decide the standard ease of basic sleeve pattern.

    The purpose of this paper is to determine the effect of repeated shearing stress on fabrics in washing bath, and a model device was designed for this purpose. Artificially soiled cotton fabrics soiled with carbon black and palmitic acid were washed in synthetic detergent solution by the test apparatus.
    Dm (repeated shearing effect) and p (ration of Dm to DM) were obtained as follows :
    Dm= DM-Dn, p=100Dm/DM = 100 (DM-Dn) /DM
    where DM and Dn are detergencies under repeated shearing stress and nonrepeated-shearing respectively.
    The results obtained were as follows :
    1. Interpretable relation was observed between DM/shearing speed curve and Dm/shearing speed curve.
    2. p values were between the range of 3070% according to the shearing speed.Dm3. It was found that repeated shearing of fabrics is an operation to increase the effective surface of the fabrics in washing.

    Horizontal trunk sections of each 20 mm of height above and below the chest line were obtained from 2 female and 3 male plaster torsi by projection-type moire topography. On each section, prominent points, hollow points and median points of anterior, posterior. and lateral walls of the trunk were read as rectangular coordinates. The following observations were made :
    1) The prominent line on the bust courses quadrilaterally in the females and elliptically in the males. The prominent line course on the back is a loose gourd-shape in the females and the endomorphic male, whereas that of the mesomorphic and ectomorphic males is an acute triangle. The prominent line on the side courses down from upper back to lower front of the body.
    2) The hollow line on the back is rather sigmoid.
    3) Anterior and posterior median lines are not always vertical. In particular, the latter is slightly sigmoid.
    4) The alteration of ellipticity of trunk sections between chest line and waist line is relatively simple in the females and the endomorphic male, but in the mesomorphic and ectomorphic males the roundest section is observed at the epigastric region.

    The most important factor that determines the housework of housing life is the qualitative and quantitative characteristics of the housing and living environment. The urbanization and cityward drift of the population that accompanied the rapid economic growth since 1955 has given rise to a serious housing shortage.
    To cope with this, a trend toward concentration of housing units, particulary in the development of public housing complexes, has emerged. Though this has, for the moment, solved the problem, the low quality of Japanese housing is yet to be tackled. This is a factor that determines the housework of housing life.

    This report contains how to care of children and thoughts on childcare.
    The results of our research were as follows :
    1) Rental napkins are used scarcely but merchandised baby foods are popularly used by more than 60% of housewives.
    2) Husbands of employed-mothers take children to nursery school more than husbands of non-employed mothers. Most husbands scold their children and take care of children when they have a bath, but few husbands take care of their children's excretion and belongings.
    3) Usually the nursery school is highly valued by employed mothers compared with non-employed mothers.
    4) 10% of all mothers watched their children playing by reason of protection from danger. 70% of mothers who belong to Stage 1 watched by reason of their children being too small. These mothers aren't satisfied because they cannot enjoy their hobby, acquire culture, and play sports. They are busy with house-work even during their children's midday nap.

    The purpose of this paper is to analyze the present state of the managerial housework on food, clothing, housing, and childcare, and to clarify wives overall evaluation of housework. The results of analysis were as follows :
    1) 65% of wives went shopping for food everyday, because it is their daily routine.
    2) Husbands of most wives helped with some housework, like making the bed, shopping for food and so forth. Husbands of employed wives helped more then those of non-employed wives.
    3) Though many wives valued housework highly, they thought that employment and hobbies were also important. Wives who valued housework very highly believed that children under three years old should be brought up by their mothers.
