Dry red beans which had been soaked in water were boiled experimentally in four different solutions : distilled water, 1% NaHCO₃, 1% K₂Al₂ (SO₄) ₂, and hard water (0.0307% CaSO₄ · 2H₂O).
The conversion of insoluble into soluble pectin in the beans during the heating process was measured. Also the microscopic observations of the cells were made. The degradation of pectic substances and destruction of cell walls were most obvious with 1% NaHCO₃.

Some factors which affect the whipping properties of cream were studied.
The whipping properties were decided by the following physical characteristics :
1) Degree of whipping (appearance)
2) Whipping time
3) Over-run
4) Firmness (with Curd Meter)
5) Leakage of serum
The results obtained are summarized as follows :
1) Low temperatures must be maintained at all stages of handling and whipping cream.
2) Cream whipped at medium speed (G-E mixer Speed 5) has the best quality.
3) Sugar blended with cream deteriorates the whipping properties of cream.

Experiment was carried out to obtain the best quality of cooked rice. In one of the methods rice was pre-soaked in water for a certain period of time, and in the other method rice was not pre-soaked but the cooking time was extended.
Comparing these two methods, the conclusion was formed through taste-testing and some other objective methods. The conclusion we arrived at was that the pre-soaked rice required a short. time for being cooked well, but pre-soaking might not be necessary if the cooking time was extended.

In former studies, among many factors affecting the deterioration of frying oil (extracted fromrice), a significant difference was recognized between the oil surface areas 0.4cm²/g and 0.2cm²/g, with probability of 95%.
Experiment is carried out to make clear the effect of the area which ranges between these two values on the deterioration of oil, and also to determine the suitable amount of oil for frying.
Three different areas of oil, 0.4cm²/g, 0.3cm²/g and 0.2cm²/g, are employed. The temperature of oil is kept at 180°C for 1, 2, 3, and 4 hours respectively.
The result shows that deterioration of oil is probably delayed when the area exposed to the air is less than 0.3cm²/g, and the cylindrical utensil which contains the oil over 3.5cm in depth should be used.

There would be many ways to combine ingredients to make cookies. The problem is to determine a proper proportion of basic ingredients to make good recipes. The paper reports our experiment on the relati on between proportion of ingredients and taste of cookies.
Twenty-five samples were prepared according to “Simple Lattice Design” method so as to make the sensory evaluation more scientific. Their “hardness” was measured by means of Texturometer to see the effect of proportion on the taste of cookies. Change in the taste of cookies which takes place during the preservation in different ways was also investigated.

In an effort to examine the velocity of water absorption of yarns, as a fundamental study of water absorption of cloth in general, the author made model yarns equivalent to Vinylon 70D, i. e. multi-yarns of Rayon, Vinylon, and Moron. Effects of fiber materials and their twist on the water absorption were investigated.
1) As for Rayon, which is a hydrophilic material, yarns without twist showed the highest water absorption. The rate of water absorption decreased when the yarns were twisted. It re-mained the same, however, even when the twist of yarns was made tighter.
2) Tetoron, which is hydrophobic, showed the lowest degree of water absorption when the yarns were not twisted. The rate of water absorption increased when the yarns were twisted, but it decreased when twisting became tighter.
3) Vinylon, which is somewhere between Rayon and Tetoron so far as its affinity for water is concerned, showed, like Rayon, the highest degree of water absorption when the yarns were not twisted. But the rate of water absorption, unlike Rayon, continued decreasing as twisting increased, and remained the same over the twisting of 6 per cm.
In the case of tightly twisted yarns of Vinylon, the rate is the same as Tetoron, and lower than Rayon.
It is fairly difficult to theorize about this phenomenon, and our investigation is still going on.

This paper describes the experimental studies on the very slow warm air flow sent off upwards to fiber assemblage from a fine tubing. Schlieren method was employed to make the stream visible.
Results show that when the warm air stream reaches the surface of the fiber assemblage most of it reflects downwards at the surface, some of warm air stream penetrates into the fiber assemblage, and a little portion of it flows out through the fiber assemblage upwards from the upper surface.
These phenomena are analogous to the phenomena observed in electrons which are projected to a solid and show backscattering and penetration in the solid.

The beauty and the aesthetic appeal lie in to an important extent how clothes drape on a person. One reason why foreign clothes drape differently is that we can say that clothes drape in three dimensions. This has been studied by many investigators by different kinds of instruments.
In Kimono (Japanese clothing) there is not much draping and we can say it has two dimensions. In the two dimensional type of Kimono, the draping is produced with the sagging and the rounded effect along, for example, the bottom seams of the sleeve (tamoto) and the hem of the skirt (suso).
After experimenting, the author found out that the sagging at the hem and sleeve end was due to the gradual sagging of the woof thread itself.
In order to make the Kimono look flat and finished and not show any sagging lines, the correction is made in the making, the art of sewing, and by ironing the seam.

1. Clothes should be constructed so as to be beautiful and functional. The present experiment has been planned, continued from last report, in order to collect data on the function of clothes, and to ascertain how much Arm Hole should be made larger to attain its best function.
2. Limiting the motion of the brachium to up-and-down movements in the same way as last report, we measured the changes in shape and area of the skin which encircles Arm Hole by following up the traces of marks on the skin using Stroboscope SS-4-A (Toshiba).
3. It has been disclosed by this experiment that the transfigurations of the skin caused by up-and-down movements of the brachium are more delicate and complex than usually supposed. Our method can show those movements and changes in both area and shape of the skin through the loci of marks on the skin, which cannot be shown by the distortion of lines drawn on the skin.

There are various kinds of lining fabrics on the market in these days, but for all the importance of lining in the clothing construction there seems to be few literatures on lining fabrics.
In an effort to clarify the efficiency of these materials as the lining, some tests have been carried out from the standpoint of clothing construction.
Samples tested are six cupra-rayon fabrics, one silk-rayon fabric, one silk-polyester fabric, two silk fabrics and two polyester fabrics.
The items tested are as follows :
(1) Fabric Strength (2) Fabric Shrinkage (3) Fabric Flexibility
(4) Yarn Slipperiness (5) Treatments for End Uses
The results obtained are as follows :
(1) Polyester fabrics have the most superior properties for lining.
(2) Union fabrics are fairly well for lining.
(3) Silk fabrics are better than cupra fabrics for lining.

Many kinds of fabrics such as cupra fabric, rayon-silk fabric, silk-polyester fabric and silk fabric are now much used as lining and 50S silk thread prevails on the market to sew these lining fabrics.
From the viewpoint of end uses, seam tensile strength and seam puckering of lining fabrics have been measured and authors have tried to find the best kind of thread and length of its stitches for lining fabrics. The results obtained are as follows :
1. 50S silk thread appears not to be suitable for cupra fabric. Instead 80S cotton thread, 80S polyester thread and 80S nylon thread are suitable for cupra fabric, according to the order mentioned above. Five or six stitches per cm of the cloth are preferable to sew in the warp direction with cotton or polyester threads and 4 or 5 s. p. c. for the weft direction sewing. The nylon thread produces better results for both directions of the cloth when the number of stitches is 3 or 4 s. p. c.
2. For union cloth 4 s. p. c. of 80S nylon thread is suitable for both warp and weft direction sewing.
3. Four or five s. p. c. of 50S silk thread is suitable to sew silk fabric in warp direction and weft direction.

The oral questionnaire on family budgets should be in simple form. So the imperfection in the form and the uncertainty in the hearing are apt to be made. As one of the revising methods, I use the cash inspection. This is based upon inspecting whether or not the accounting balance agrees with the savings. This is one of the self-inspection-systems of the survey. But this method can inspect only cash and not goods ; if we make the same mistakes in the sums of the incomes and the expenses, we cannot find the error.
Therefore, this method cannot be taken to be the perfect inspection method. But this deficiency can be compensated by the skill of the survey and the system of the oral questionnaire.
