In order to know the similarity of the electrophoretic protein patterns, distributional aspects of the frequency in each protein band, differences of protein patterns between female and male, and the number of the total protein bands of each variety in the haemolymph of the silkworm pupae according to their geographical origin, the silkworm varieties, and both the sexes, variable electrophoretic protein patterns were observed by polyacrylamide gel electrophoresis, using the silkworm strains which have been reared in the sericultural experiment station. 1. The total number of electrophoretic protein bands classified were twenty-eight, and nearly fourteen bands were shown by each variety on an average. 2. According to their geographical origin, the mean values of the similarity were 20.0%, 28.3% and 14.3% in Japanese, Chinese and European respectively, and the highest similarity was observed between Chinese varieties. 3. The similarity of 129 varieties were tested and it was 22.5%, 23.5% in female and male respectively. 4. The electrophoretic protein patterns in 129 varieties were tested and variation was found in 109 patterns in female and 112 in male. 5. The frequency of the each specified protein band in female and male having variation in protein bands in each variety was found averagely 6.6%. 6. The distribution frequency of the classified 28 protein bands in both the sexes within each geographical origin was variable from 0% to 100%. 7. Among the classified 28 protein bands, HP 11 protein band was found common in all the varieties tested. 8. HP 3 and HP 4 protein bands in female showed high density in electropherograms than in male.

The purposes of this study were to classify purchaser into three groups by purchasing price for preschool children's wear and to identify the differences of clothing values, lifestyles, considerations in purchasing preschool children's wears, and purchasing places among the classified three groups. One hundred forty people living in Seoul with children aging between 3 and 7 were surveyed for this study. Cluster analysis, frequency analysis, chi-square analysis, ANOVA, and scheffe test were used to analyze the data. The findings of this study were as follows; 1) Purchaser were classified into three groups, namely the group of high purchasing price(HP), the group of medium purchasing price(MP), and the low purchasing price(LP). The HP had more monthly average income than the LP. 2) The HP showed high concerns in aesthetic and social clothing values, the MP considered social clothing value more important, while the LP showed high concern in economic clothing value. 3) Regarding the differences in lifestyles, the HP was more fashion-oriented and leisure-oriented, the MP was fashion-oriented, while the LP was economy-oriented. 4) When purchasing preschool children's wear, the HP showed high concerns in design and brand, the MP in activity, laundry-and-care, and brand, and the LP in activity, laundry-and-care, and price. The HP mainly purchased preschool children's wears in department store and imported goods store, the MP in department store, traditional market, and discount store, and the LP in discount store.

The stirred and thixoformed $SiC_p/AZ91HP$ Mg composites are studied on the basis of microstructural analysis using transmission electron microscopy (TEM). The products of interfacial reaction are identified as $Mg_2Si$, MgO and $Mg_{17}Al_{12}$ phases and the crystallized phases are found to be orthorhmbic $Al_6Mn$ and decagonal T phases. It is shown that $Mg_2Si$ and $Mg_{17}Al_{12}$ phases are found at the surface of $SiC_p$ and $Al_6Mn$ is found near interface and crystallized on the matrix. Phase identification is carried out by crystallographic work based on primitive cell volume, zero order Laue zone (ZOLZ) patterns and single convergent beam electron diffraction (CBED) patterns containing higher order Laue zone ring from a nanosized region.

The purpose of this study was to evaluate the tooth whitening and properties of an enamel surface after treatments with tooth bleaching agents that contained dicalcium phosphate dihydrate (DCPD) and hydrogen peroxide (HP). Thirty specimens were obtained from fifteen premolar and were randomly divided into three groups (n=10): 1, 3.5% HP + 0 g DCPD; 2, 3.5% HP + 0.1 g DCPD; 3. 3.5% HP + 1 g DCPD. All groups were bleached 8 hours per day for 14 days. With increasing DCPD concentration, the pH values in the agents increased, making it less acidic. However, there was no statistically significant difference (p>.05). As the concentration of DCPD was increased, the concentration of Ca and P was also increased. In all groups, after the tooth whitening, the tooth color was found to have a value of $L^*$ (p<.05). All groups showed significantly decreased enamel microhardness compared to their baseline (p<.05). The percentage microhardness loss (PML) of the group A1 and A2 were significantly lower than that of group A3. The obvious variation of morphology was observed on enamel surfaces in group A1. Following an analysis of the constituents of enamel surface after bleaching, as DCPD content was increased, the amount of Ca and P was increased. In this study, the experimental results suggest that DCPD/HP agent less demineralization changes such as the erosion morphology and hardness loss without compromising whitening efficiency.

This study examined how the participation rates contribute to subjects' outcomes after a nutrition education (once/week) and exercise (3 times/week) intervention program for 12 weeks in 44 obese female subjects. The subjects were divided into two groups: high-participator (HP) or low-participator (LP) groups according to their participation levels based on the median visit value (30 visits out of a total of 48 visits). Daily nutrient intakes assessed by a 24-hour recall, body composition, blood lipid profiles and physical fitness were measured at baseline and after 12 weeks. After the intervention, weight, BMI, percent body fat, and the waist-hip ratio were significantly decreased in the HP group. In addition, the HP group had a greater rates of changes in weight (HP group: -6.6% and LP group: -3.1%, p < 0.01), BMI (-7.0% and -3.2%, p < 0.01), percent body fat (-7.8% and -4.2%, p < 0.05), and waist-hip ratio (-3.1% and -0.4%, p < 0.01) compared to the LP group. Energy-adjusted protein, fiber, potassium, vitamin $B_1$, vitamin $B_6$, and vitamin C were significantly increased in the HP group. The HP group showed a significant increase in HDLcholesterol and a decrease in blood pressure, total cholesterol, LDL-cholesterol, triglycerides, and atherogenic index (AI). While the muscle endurance, muscle strength, power, agility and flexibility were significantly increased in the HP group, agility and balance were improved in the LP group. In addition, dietary behavior score was significantly increased and stress score decreased in the HP group compared to the LP group. High participation rates were correlated with the improvement of the nutrient density (protein, fiber, potassium, Vitamin $B_1$, Vitamin $B_2$, Vitamin $B_6$ and folate), anthropometric parameters (body weight, BMI and percent body fat), serum lipid profiles (HDL-cholesterol, Triglyceride, and AI) and physical fitness (muscle endurance) adjusted for age, menopausal status, alcohol drinking, nutritional supplement use and baseline BMI. Our results suggest that high participation in nutrition education and exercise program was effective not only for weight reduction but also for the improvement of physical fitness in obese women.
