工芸染色用酸性染料の配合染色における色の発現と染色堅ろう度

In dyeing craft fabrics, mixture dyeing often fails to develop the desired colors. Interactions between the mixed dyes, and between dyes and substrate polymers hamper the color development and uniformity. This study reports on how the colors on silk and nylon fabrics develop when two commercially available acid dyes are mixed and used. In the absorption spectrum of the solution of the acid dyes mixed, the reflectance spectra of the dyed fabrics, and the color differences of the dyed fabrics, were measured to find the reasons for the failure. The fastness to light of the dyed fabrics was also measured. As a result, several important points to be noted in dyeing were shown

東京とハノイの衣生活 : 女子学生の着装意識と衣服管理

This paper investigates why and how female college students at Showa Women\u27s University and at Vietnam National University wear and care for their clothes. One-hundred-eighty students at Showa Women\u27s University and forty-three female students in Vietnam National University responded to a questionnaire about their clothes. 1. With regard to motivation, the students in both countries are interested in high fashion. However Hanoi students seem to base what they wear on individual notions of what is fashionable, Tokyo students tend to choose their clothes depending on other\u27s preferences. In addition, students in Tokyo are more concerned with appearing slender than students in Hanoi. 2. In Hanoi, fewer students have skirts. There are historical reasons for this. 3. In both countries students purchase ready-made clothes. In Hanoi 80 percent of the students also wore custom-made clothes. 4. More students in Hanoi are bothered by their clothes sticking to their skin due to the high humidity than are students in Tokyo. This contrast is caused by the different climates of the two countries and by the clothing materials prevalent in each country. 5. The rate of washing by hand versus washing with a machine is clearly different between Tokyo and Hanoi. What students wear, and how they care for their clothes in Tokyo or in Hanoi respectively depends on factors, such as climate condition, traditional clothes, culture, economic situation and social background

不妊と肥満に関する栄養学的研究

The leptin known as ob gene regulates body weight by affecting the appetite and thermogenesis. Leptin was an important mediator of the reproductive function. In this study, they were aimed at studying causation of the infertile and the obesity on the role of nutrition. The subjects were 11 overweight women (25≦BMI) with normally ovulating, and 98 overweight women (25≦BMI) with infertile. The methods of investigation were as follows; physical measurement, biomedical testing, investigation dietary records, motion and time study and dietary habits of each subject. The concentration of serum leptin was correlated with body fat mass in the infertility and normal ovulation groups. Furthermore, the infertility groups had many intakes of the meat in comparison with the normal ovulation group. In addition, the groups had to skip a meal with dietary habits, and meal intake time was irregular. These data demonstrate that infertility groups may have reflected a nutritional abnormality, suggesting that, regarding irregularity of eating behavior and skipping meals is responsible for infertility
