  • The purpose of this study was to investigate the colorfastness of cotton and silk fabric dyed with extract of Lotus leaf princeps. The experimental items were classified into mordanting treatments, fabric components and kind of mordants. The experimental test was done by laundering, abrasion(dry/wet), perspiration(acid/alkali) , light fastness, color difference by C.C.M(computer color matching) system and K/S test. The summarized findings resulting from the experiment and investigation are as follows: In the C.C.M and K/S test on mordanting method and kind of fabrics, co-mordanting treatment method and protein fabric (silk) were the most effective. Especially, Fe mordanting treatment was higher than Al, Cu, Cr and none-mordanting. In colorfastness on the mordants, perspiration and laundering fastness showed high grade (4-5) but grades of perspiration(2-3/4) and light fastness(1-3) were low.

  • Various kinds of legumes have included as essential foods in Korean diet. However, a little attention have been paid on variety of those beans other than soybean. Main purposes of this study is to evaluate the protein quality of raw and cooked, red mung bean. Eighty male, sprague-Dawely rats weighing 50 gram were devided into 16 groups, five rats each. Casein protein from red and mung bean were used was included to after true digestibility of the protein of legemes. After 4 weeks feeding period animals were sacrificed and following data: all determined food intake, body weight gain, F.E.R., pp.E.R. and weights of liver, kidney heart, spleen, testis, pancreas, skeletal muscles. Food intake, body weight gain, F.E.R., pp.E.R. of casein group were higher than those of experimental groups (red bean, mung bean) body weight gain was increased with protein increment in the diet in all groups. The weight of liver showed significant difference between standard group and experimental group. (red bean, mung bean) The nitro gen content of liver and muscles were increased with level of protein in the diets.

  • This study was designed to find out the nutritional defect of general Korean diet and the effective way of nutritional supplementation. Seventy weanling Sprague-Dawley male rats weighing 51.8$\pm$0.9g were blocked into ten groups and fed ten different diets ad libitum for eight weeks: Standard groups(st gp) was given 72% sugar-20% casein diet: Cereal-vegetable group(c-v gp) was fed cereal-vegetable diet(c-v diet) composed of rice, barley, soybean, spinach and cabbage: the other eight groups were fed c-v diets supplemented with casein, vitamin $B_{2}$, calcium, vitamin A, vitamin B2 and A, vitamin A and calcium, vitamin $B_{2}$ and calcium, vitamin A and $B_{2}$and calcium, respectively, on the basis of each nutrients content of standard diet. The results were as follows: 1. Food intakes and body weight gains in all the experimental groups were significantly lower than st gp. Among experimental groups, casein gp and vit B2 gp tended to gain more body weights than c-v gp. 2. Through all the experimental period, F.E.R., pp.E.R., and NDPcal% did nod show significant differences among all the experimental groups and st gp. 3. The weights of liver, kidney, and gastrocnemius were significantly lower in all the experimental groups as compared with st gp. But brain and sex organ weights did not show differences among all the groups. 4. Nitrogen contents of total carcass, liver, and gastrocnemius in all the experimental groups tended to be increased as compared with st gp, and among experimental groups, they tended to be increased by casein supplementation and decreased by ca supplementation. 5. Apparent nitrogen digestibility, urinary and fecal nitrogen excretion, the amount of nitrogen retained, and N.P.U. did not show any significant differences among all the groups. 6. Serum total protein concentrations did not show any significant differences among all the groups.

  • An extensive body of research on the effects of country-of-origin has emerged in the international marketing and business literature streams. Nonetheless, extant studies do not satisfactorily demonstrate whether and how a foreign firm's choice of market entry mode influences consumers' purchase intentions of its product in country-related affect contexts. Using a survey and an experimental design, we aimed to provide evidence of the effects of the choice on consumers' evaluation and attitude of its product in an animosity context and in a national image context. Through the survey, we collected data regarding consumer animosity, national image, product evaluation, and product attitude from 185 university students and tested the hypotheses that consumer animosity and national image have effects on foreign product evaluation and attitude. The results of the survey research show that personal animosity has a negative effect on consumers' evaluation of foreign products and that a country's image regarding economics has positive effects on consumers' attitude toward foreign products as well as consumers' evaluation of foreign products. In the experimental design, we divided subjects into four groups and exposed them to several descriptions of hypothetical purchase situations. Conducting a 2 (market entry modes)${\times}2$ (country-of-origin) ANOVA, we tested the hypothesis that a market entry mode influences foreign product evaluation and attitude. The results of the experimental study reveal that in a high country-related product association (Germany), market entry modes have insignificant effects on foreign product evaluation and attitude. In addition, in a low country-related product association (China), international partnership has more positive effects on foreign product evaluation and attitude than does exporting.
