JOURNAL FREE ACCESSSome properties of chlorophyllase in spinach were studied and the following results were obtained.
The optimum temperature and pH for chlorophyllase activity were 2530°C and pH78, respectively. The optimum acetone concentration for its reaction was about 50%.
The enzyme was little affected by heating at 90°C for 1 minute, while greatly inactivated by heating at the same temperature for 5 minutes.
The enzyme was deteriorated by light illumination and by Ca2+, Mg2+, Zn2+, and Fe3+, especially by Fe3+.
The enzyme was harmed by monoiodo-acetic acid, K3Fe (CN) 6 and ascorbic acid. NaF and EDTA also inactivated the enzyme.View full abstractDownload PDF (594K) -

JOURNAL FREE ACCESSThe iron content of chicken meat is not found in any of the Japanese Food Composition Tables.
Using isotopes, Dr. C. V. Moore investigated the absorption of iron of chicken meat and found that it was greater than 30%, while each absorption of iron of chicken egg, chicken liver, spinach, lettuce, and dried yeast was only 10%.
The author investigated iron content of meat of ten white Leghorn chickens. Both raw and water boiled meat at breast, thigh, and drumstick were used for the investigation. The differences between iron contents of raw thigh meat and boiled thigh meat, and between those of raw drumstick meat and boiled drumstick meat were significant whereas the difference as for breast meat was not significant. However, when the chicken meat is considered as a whole, the loss of iron by boiling with water was significant.
Iron contents of some of the daily foods obtained by analyses with α α'-dipyridyl were lower than those shown in the composition tables.
Reasonable estimates of the average iron contents of raw and boiled chicken meat are 2, 10mg% and I. 85mg%, respectively.View full abstractDownload PDF (373K) -
Amino Acid SolutionYasuko GOTOH, Tokiwa SHIBATA1970 Volume 21 Issue 7 Pages 428-431
Published: December 20, 1970
Released on J-STAGE: March 09, 2010
JOURNAL FREE ACCESSSamples of thirteen kinds of amino acid solution (1/100 mol) were heated for 120 min. at the pressure of 1kg/cm2, making analysis of amino acids by Beckmann/Spinco Amino Acid Analyzer 120-B every 10 min. to provide their heat decomposition graph.
The work has yielded the following results.
Glutamic acid has the highest heat decomposition rate of 68% in 120 min. The second highest decomposition rate, 8%, is obtained with tryptophan. Other amino acids, however, have the rates of under 3%.
The experimental formulae which approximate the heat decomposition curves of respective amino acids wera pursued and differences in the modes of decomposition were discussed. The periods of half decay of both glutamic acid and tryptophan were obtained.View full abstractDownload PDF (424K) -
A Survey at Dry Cleaner'sKiyoko FUJII, Reiko SUGIHARA, Mizuho YOSHIDA1970 Volume 21 Issue 7 Pages 432-436

Released on J-STAGE: March 09, 2010
JOURNAL FREE ACCESSAn actual survey of soil redeposition in dry cleaning baths in use at dry cleaner's shops has been carried out, and some laboratory tests by the same cleansing agent as dry cleaner's shops' and by the agent re-dispersed with soils collected from a certain dry cleaner's working bath have also been performed.
Results are summarized as follows :
1) In the actual survey, it was observed that the soiling of cotton, wool and acrylic cloths by dry cleansing agent reached detectable degree. The soiling degrees obtained with three sample materials were not identical at different shops.
2) In laboratory tests of the same dry cleansing agent as that used at dry cleaner's, no correlation has been observed between the acid value or turbidity and soil redeposition of the liquid.
3) In the cleansing agent prepared by re-dispersing soils extracted from actually used liquid at a dry cleaner's, some definite relations were observed between soil concentration and acid value and also soil concentration and turbidity. A regular correlation was also observed in this liquid between soil concentration and the degree of soil redeposition on all of the three kinds of test cloths.View full abstractDownload PDF (557K) -
Experimental Observations of Surface Condition of Single Filament by Optical Microscope and Electron MicroscopeAkiko MINAMISAWA, Haruko TAKENAKA1970 Volume 21 Issue 7 Pages 437-441

JOURNAL FREE ACCESSBoth dry and wet single filaments of cotton and polyester are observed under optical microscope and electron microscope. The wet filaments are obtained by keeping the filaments in the atmosphere of R. H. 100% for about one day.
The surfaces of both dry and wet polyester filaments have smooth appearance.
There are many rumples on the surface of cotton filament kept in 100% R. H. The surface is made considerably larger by these rumples.
The difference in surface structure between cotton and polyester seems to explain the difference in the moisture absorption power between the two materials.View full abstractDownload PDF (2360K) -
Deterioration of Humidity ConditioningAbility of TextilesAkiko MINAMISAWA, Haruko TAKENAKA1970 Volume 21 Issue 7 Pages 442-444

JOURNAL FREE ACCESSResults obtained by the thermogrammetric analysis of filaments are reported in this paper.
Cotton filaments which had been kept in the atmosphere of R.H. 100% for about one day showed remarkable hydroextracting as the temperature of the capsule of thermobalance rose.
It was found that cotton samples which had been left in the perfect dry atmosphere still had some residual moisture.
Polyester filaments which had been kept in the dry atmosphere showed increase in their weight by temperature rise, instead of decrease. When they had been kept in the atmosphere of R. H. 100% they decreased the weight by heating of the capsule because hydroextracting was induced.
The cotton and polyester filaments which had been cut with a sharp knife about 1mm long were also analyzed by thermogrammeter.
These short filaments showed some decrease in the absorption power compared with the long ones.View full abstractDownload PDF (1176K) -
Physical Characteristics of the Youths Referring Primarily to the Slope of ShoulderKiyoko TAKAHASHI, Ai GANBE, Uta KONOTO1970 Volume 21 Issue 7 Pages 445-450

JOURNAL FREE ACCESS1) 746 Fukushima youths above the senior high freshman age were measured in summer, 1967.
2) Compared with the national average, they are slightly shorter and fatter.
3) Gradual growth is observed before they reach the high school senior year in stature, chest girth, shoulder breadth, neck-base girth, thickness of subcutaneous fat of the back, and bodyweight. Thereafter the growth almost stops in the female except for chest girth and bodyweight the male shows slight growth in all items but stature which makes large increase.
4) Angles of shoulder slope are larger than those of junior high pupils. There is a significant difference between the 3rd year pupils of junior high and freshmen of senior high in both sexes. Females always have more sloping shoulders than males, but this sexual characteristic is less obvious in our subjects than in the youngers. About 82% of the males have the angles ranging from 17°to 26°, and about 80% of the females from 19° to 28°. In each sex, the angles are, unlike those of the youngers, more densely distributed in the larger value region. This is especially conspicuous with males.
5) There is very little correlation between shoulder slope and other measured items.View full abstractDownload PDF (728K) -
Teaching Method of Sewing in the Meiji Era (Part 1)Tetsuko HIGUCHI1970 Volume 21 Issue 7 Pages 451-458

JOURNAL FREE ACCESSThis research has been done in an effort to systematize some characteristic features in the development of the method of teaching clothing in Japan and to establish a basis for future studies.
The teaching method of sewing in the Meiji era is classified into two, that is, the method employed before the thirtieth of Meiji and that employed after that year.
This paper, which concerns with the first period, deals with two pioneers, Mr. Miyoji Hozawa and Mr.Tatsugoro Watanabe.
1. Materials for instruction were standardized, and the organic method took the place of the previous separative one.
2. Mr. Hozawa made a great contribution to analytical method (from sectional sewing to organic one) and to working out wall-charts.
3. Mr. Watanabe worked out the methods of miniature models (from making miniatures to actual sewing), Tsumoridachi, charts and catechism.
.4. These developments were based upon the introduction of organic teaching method, object-lessons, and developmental instruction.View full abstractDownload PDF (2264K) -
