In this paper, we consider linear elliptic systems from composite materials where the coefficients depend on the shape and might have the discontinuity between the subregions. We derive a function which is related to the gradient of the weak solutions and which is not only locally piecewise Hölder continuous but locally Hölder continuous. The gradient of the weak solutions can be estimated by this derived function and we also prove the local piecewise gradient Hölder continuity which was obtained by the previous results.

This study was performed to determine the optimal month of harvest between May and July for wild peach (Prunus davidiana) by comparison of functional materials. The general composition, amino acid and vitamin (A, C, and E) content, and antioxidant activity were determined. With respect to the general composition of wild peach according to the month of harvest, wild peach harvested in May (HMP) and July (HJP) contained mostly carbohydrate, the contents of which amounted to 77.37 g/100 g and 77.92 g/100 g, respectively. The total amino acid content of HMP and HJP were 675.29 mg% and 573.25 mg%, respectively. Regarding the vitamin contents, vitamin A (retinol), E (${\alpha}-tocopherol$) and C in HMP were higher than those in HJP. The total polyphenol content of HMP (218.37 mg TAE/g) was higher than that of HJP (71.45 mg TAE/g). The total flavonoid content of HMP (64.95 mg RE/g) was also higher than that of HJP (32.67 mg RE/g). Moreover, the DPPH and ABTS radical scavenging activities ($IC_{50}$) were higher in HMP ($137.18{\mu}g/mL$ and $157.15{\mu}g/mL$) than those in HJP ($160.10 {\mu}g/mL$ and $186.01 {\mu}g/mL$), meaning that the former produces better antioxidant effects. It can be concluded that wild peach harvested in May contained higher functional materials such as vitamins and amino acids and had a higher antioxidant effect, than wild peach harvested in july.

Recently, increasing interests in local foods have been highlighted along with active efforts and activities from autonomy organizations to develop local cultures and promote local economies by generating value added products and profits through the development of local foods. Subsequently, useful effects might result by making local foods attractive to tourists, such as by using indigenous Gimpo products to make menu items that incorporate the social, economic, and cultural aspects of the Gimpo area, and contributing to its food culture, the development and use of its indigenous products, and promoting local restaurant businesses, etc. The items of the survey used to select the local food menu items to be developed were limited to ideas offered by expert groups, and were implemented by a new menu development process. In order to derive the menu items to develop, the following method was applied: a brainstorming session with experts to generate and draft ideas, a questionnaire to chefs and cooks in special grade hotels is Seoul to select the menu items to develop from those drafted, and sensory evaluations by experts to evaluate the developed items. Frequency analysis and technical statistical analysis were performed using the SPSS 12.0 program package, where 13 kinds of local foods were ultimately developed using indigenous products of Gimpo. The developed local food menu items were rice & grape sujaebi, grape sikhae, fried rice embryo bud, grape yanggaeng, rice pancakes, rice spaghetti, grape seed oil dressing, grape sauce, rice pizza, grape pie, rice & grape ice cream, grape chocolate, and rice roll cakes.

A hierarchical loglinear model comparison method is developed which is based on the well kmown partitioned likelihood ratio statistiss. For any paels, we can regard the difference of the geedness of fit statistics as the variation explained by a full model, and develop a partial test to compare a full model with a reduced model in that hierarchy. Note that this has similar arguments as that of the regression analysis.

The purpose of this study was to verify the difference of middle school students' eating disorder behavior and scholastic adjustment according to the gender and weight group and evaluate correlations between their eating disorder behavior and scholastic adjustment. A survey was conducted in middle school second graders attending five schools located in Seoul. Results from 355 questionnaire sheets were utilized for statistical analysis, and the results were gained as below: With regard to eating disorder behavior by gender, female students showed more eating disorder behavior than male students (p < 0.01); however, scholastic adjustment did not indicate significant differences by gender. According to the result of analyzing scholastic adjustment according to the weight group, the obese group showed lower scholastic adjustment (p < 0.05) and adjustment to studying (p < 0.01) than other groups; however, the eating disorder behavior, attachment to school, and adjustment to school did not indicate significant differences. According to the results of analyzing scholastic adjustment by eating disorder group, the normal group showed higher adjustment to studying than the risky group (p < 0.01). And scholastic adjustment, attachment to school, and adjustment to school did not indicate significant differences. The eating disorder behavior showed negative relationship with adjustment to studying. They showed more eating disorder behavior, their adjustment to studying became lower. Therefore, it is necessary to provide nutritional education at home and at school for them to have appropriate dietary habits as well as health education for them to maintain normal weight.

While environmental pollution being developed, there have been some cases that residents on certain parts of Seoul area have cultivated vegetables in a small scale, and consumed the produce of theirs thinking them not polluted. Therefore the need for study about whether those vegetables and soil were polluted was growing. In this study, Seoul area (Tobong-dong, Chang-dong, Wolgyedong, P'il-dong, Oksu-dong, and Karibong-dong) and Kyanggi area (Changhang, P'och'an, Kap'yang, Yangp'y~ng) where pollution was thought to be less severe than that of the former were selected for the sampling area. Cabbage, pumpkin and young pumpkin were sampled and dried to be analyzed the contents of Cd, Cr, Cu, Ni, Pb, Zn, and moisture content was also analyzed. And at the same time 0.1 N-HCl soluble heavy metal content of soil was measured, and the results obtained were descrived as follows. Heavy metal contents of soil in Seoul and Kyonggi were Cd 0.184 ppm, 0.118 ppm, Cr 2.355 ppm, 0.441 ppm, Cu 29.16 ppm, 3.331 ppm, Ni 1.650 ppm, 0.829 ppm, Pb 26.77 ppm, 4.696 ppm, Zn 57.47 ppm, 14.94 ppm respectively. Heavy metal contents of cabbage in Seoul and Kyonggi were Cd 0.407 ppm, 0.241 ppm, Cr 0.388 ppm, 0.402 ppm, Cu 6.853 ppm, 4.486 ppm, Ni 1.479 ppm, 0.878 ppm, Pb 0.812 ppm, 0.258ppm, Zn 112.2 ppm, 54.86ppm respectively. Heavy metal contents of pumpkin in Seoul and Ky6nggi were Cd 0.011 ppm, 0.011 ppm, Cr 0,262 ppm, 0.197 ppm, Cu 3.302 ppm, 2.539 ppm, Ni 0.717 ppm, 0.369 ppm, Pb 0.257 ppm, 0.083 ppm, Zn 28.75 ppm, 14.01 ppm respectively. Correlation between heavy metal contents of soil and those of vegetables was represented high as a whole. In all heavy metals cabbage had higher values of concentrations than those of pumpkin (p<0.001). Concentrations of young pumpkin were higher than those of big pumpkin. It was probably due to the fact that young pumpkin containing not only inner part of pumpkin but also seeds was used as a sample. When classified by region, relatively high concentrations were observed in the samples of Karibong-dong, and in the sample of Jungtang riverside Cd was higher, and in the sample of Namsan Pb was higher than any other district.

The purpose of this study is to conceptualize the definition of school readiness specific to the context of the Republic of Korea. The school readiness test can be used as basic data to enable early childhood educational institutes to determine the general readiness of preschoolers and provide support to fit individual characteristics. For this purpose, six stages of the school readiness development process were considered, that is, draft development, primary preliminary survey, primary expert verification, secondary expert verification, secondary preliminary survey, and main survey. In the main survey, tests were conducted using the school readiness final draft targeting 344 preschoolers living in Seoul and Gyeonggi-do. The item discrimination power analysis and factor analysis for the examination area and question area were also conducted. Consequently, a test tool was developed on the basic of the results obtained, consisting of 129 items in the five areas of knowledge, function, adaptation, tendency, and attitude. The knowledge area was divided into general, linguistic, and mathematical knowledge, and the function area into fine motor function, basic living ability, expressive function, and gross motor function. The adaptation area was classified into adaptation activity, separation anxiety, maladaptive behavior, and environment adaptation; the tendency area into learning tendency; others understanding, and individual tendency, and the attitude area into rule compliance and life habits.
