The purpose of this research is to establish the method to evaluate and express physically the cutting performance of the kitchen-knife which has been usually used sensuously.
We reported already about the strain distribution in cut pieces induced by cutting action of kitchen-knife. In this report results of experimental study are described which are carried out according to the thought that some part of differences of cutting performance of various kitchen-knives may be expressed by relationship between cutting resistance force and mean cutting speed when a kitchen-knife cuts into definite specimen under various loads. In those cases, as the surface condition of knives three kinds were used, namely completely swept with benzine, oiled and watered, and variations of cutting resistance force due to different surface condition were obtained by experiment. Since it is necessary to use materials having definite characteristics for specimens to be cut throughout those experiments, oil clay was selected whose temperature was maintained between 2535°C after examining several materials and specimens were composed from layers of oil clay of two different colours piled up one by one.

Effect of ethanol on the water percentage, weight, water content and dried matter of whale meats treated at 26°C, 90°C, and boiling points was determined by using 15% ethanol solution and distilled water as control.
Water percentage, weight and water content in the treated meat became higher, while solid matter in the treated solution became lower, in proportion as the temperature dropped. However, effect of temperature on the dried matter in the treated meat was considerably small. For example, the dried matter after steeping at 26°C for 30 min was approximately the same with that boiled for 10 min. At identical temperature, weight, water content and dried matter of meat treated in ethanol solution were higher than those in water, while water percentage, as well as solid matter and soluble substance in the treated solution was lower in the former than in the latter. Approximately 100°C was necessary for the formation of solid matter. The results with a series of the treatments of steeping, boiling after steeping, boiling using freshly medium after steeping, and boiling suggested the following : (1) effect of ethanol on the tissue of meat differed from that of water, (2) a great part of solid matter in the boiled solution was formed by binding at least two components, and (3) enzymatic action or autolysis causing during a long period of steeping with water was repressed by the presence of ethanol.

Flow properties of heated cottonseed, beybean and rapeseed oils were measured by Maron-Belner type capillary viscometer. To discuss the correlation between the flow properties and chemical properties of the heated oils, acid values, peroxide values and densities of the oils were also measured. Unheated oils of soybean, cottonseed and rapessed showed Newtonian fluid, but the heated oils (170°C, 5-20 hrs.) of soybean and cottonseed showed non-Newtonian fluid at high shear stress, while the change of flow property of rapeseed oil was very little by heating. Acid values, peroxide values, densities and viscosities were increase along with the increase of heating time. The changes of these chemical properties were largest in soybean oil, then followed by the cottonseed oil. Comparing with fatty acid composition of these oils, soybean oil contains the most unsaturated bonds and rapeseed oil contains the least. From the above results, it may concluded that the flow properties of the oils are in proportional to the changes of the chemical properties and the amounts of unsaturated bonds in the oil molecules.

Ascorbic acid (AA) content and ascorbate oxidase activity in the leaves of tea plants, Thea sinensis Linn., during growth were studied.
The reduced, dehydro and total AA contents in leaves were 152, 55 and 205 mg%, respectively. In middle summer, the lowest levels of reduced and total AA (28 and 95 mg%, respectively) and remarkably higher activity of ascorbate oxidase were observed. In winter, particularly in intense cold, the levels of reduced and total AA were the highest (297 and 362 mg%) and the ascorbate oxidase activity remarkably decreased. In early summer, the enzyme activity in buds was considerably lower than in leaves, particularly in those at the top position of tree.
Reduced AA content in leaves was found to decrease during storage. Loss of reduced AA in leaves stored at 4°C for 3 days was 93, 100 and 6% for early summer, middle summer and winter-leaves, respectively. Even after 20 day storage the loss in winter-leaves was only 20%. The stability of reduced AA in winter-leaves was found significantly higher than that in other seasons.
Approximately 96% of reduced AA content in the fresh leaves was retained in tea manufactured from winter-leaves, while about 36% remained in the heated tea.

Applying the analytical geometry on the new drawing method for the neck line in an adult's Kimono, the essential guiding points for the drawing are expressed in the coordinates. When measures of the AGARIKURIKOSHI are given from 10 to 50 mm at intervals of 10 mm, the coordinates of the essential points and the centers of circles are to be calculated and these values can be illustrated in tabular.
If a measure of the AGARIKURIKOSHI is decided, the essential points and the center of the circles are to be expressed easily in the orthogonal coordinate axis on a section paper, and the drawing for the neck line is constructed mechanically by means of connecting the essential points by the circular arc and straight lines.

Purpose : The purpose of the present study is to clarify the effects of seasonal clothing on the physiological functions in man, since such studies have hardly been reported and basic data are scarce.
Method : Wearing four kinds of seasonal clothing at various experimental temperatures but the same humidity, 8 subjects underwent measurements of heart beat, energy metabolism, skin temperature and innermost temperature. The measurements were preceded on the part of the subjects by wearing material and measurement equipment in a waiting room of 24°C and by sitting still in the examination room for 30 minutes.
Results : The innermost and skin temperatures were significantly influenced by external temperature, and the temperatures of the chest and upper arms were similarly affected by the seasonal clothing. The mean skin temperature was fluctuated significantly by the change of the external temperature and clothing. The intra-clothing temperature and the skin temperature at each site showed a significant correlation. Ventilation was increased by the seasonal clothing, but the effect on oxygen uptake was not recognized.

Very few studies are available on differences and changes appearing in the sense of beauty when after a long interval a certain kind of dress is observed by different people within the same age group. The authors report on a study about woolen knitted vests of striped pattern.
Experimental conditions correspond to those reported 15 years ago. Studies were made on appearance of the sample vest when put on a body stand; analysis of color distribution, patterns and knitting method, becoming ratio when put on an actual model.
Estimation differed significantly between observations on a body stand and actual model even regarding the same sample. It was confirmed that the quality of vertically striped patterns is governed by colors, sense of beauty for color combination changes in living environment and features of the respective times.

The Safflower Yellow from Benibana can be extracted more easily into water with the rise in bath temperature. The ease of extraction increased as the temperature rose, that is, the time required for complete extraction was about 70 hours at the temperature of 25°C, 20 minutes at 50°C and only 6 minutes at the boiling point, respectively.
Silk cloth was dyed with the Safflower Yellow as extracted under several varying temperature, those dyed cloths were further treated with tin as mordant. We have obtained the following results :
When the hydrogen ion concentration in dye bath was higher than that of the isoelectric point of fibroin, the dyeing affinity between silk cloth and the Safflower Yellow was excellent.
The effect of tin mordanting on the color fastness to light and washing of dyed cloth was not very good, however, the mordanting gave quite effective color saturation.

Experiments were carried out with the 1.8 m and 2.5 m wide kitchen centers installed in Japan Corporation's houses.
The procedures of the experiments were the same as Part 1. However, those who participated in the present experiments were ten homemakers who worked in the kitchen daily, five for 1.8 m kitchen centers and another five for 2.5 m ones. They did the experimental cooking in respective kitchens.
The work has yielded the following results :
1. The step countings during the cooking showed that the 2.5 m kitchen center required less trips than the 1.8 m one.
2. According to the foot movements, the work done at the sink was more than any other places, especially in the case of the 1.8 m kitchen center. In the 2.5 m kitchen center, the mixing center located between sink and range was also used quite often. Hand motions during the cooking showed the same results as steps. For this reason a mixing center should be located between a sink and a range.
3. By reason of the narrow working space on the counter in the case of the 1.8 m kitchen center, the dining table was used supplementally, and this caused inefficiency in cooking tasks.

In the first report, we reported on the actual conditions of “the distribution intervivos” among the inheritance of the heir, based on analysis of the questionaires.
In this report, we would like to give results about two sets of questions : first, the expectation of the heir who have a claim of inheritance, and second, the actual conditions of those who already have accepted an estate.
In general, the heir-at-law wants to take more estate than others and actually do take their own legal inheritance and more. Other brother or sister declined to take their own legal inheritance and wanted to present their share to the elder brother. Parents thus want to compensate by giving inheritance intervivos or by other means to the brothers or daughters.
According to the law, “inheritance must be equally distributed” is the principle, but actually priority given to the heir-at-law is being preserved.
