This study examined the longitudinal effects of appearance satisfaction and Korean language skills on the self-esteem and school adjustment of multicultural adolescents. The study used data from 1,151 multicultural adolescents from the $3^{rd}$, $4^{th}$, and $5^{th}$ waves of the Multicultural Adolescents Panel Study (MAPS). Data were analyzed by means of descriptive statistics, Cronbach's alpha, correlation, and structural equation modeling. The results are as follows. First, appearance satisfaction and Korean language skills at grade 6 significantly predicted higher self-esteem at grade 7. Second, there was a significant influence of high levels of self-esteem at grade 7 on positive school adjustment of grade 8. Last, the self-esteem at grade 7 had a significant mediating effect in the relationship between appearance satisfaction and Korean language skills at grade 6 and school adjustment at grade 8. The results of this study highlighted the importance of self-esteem as a mediating factor in the connection between appearance satisfaction and Korean language skills as well as the level of school adjustment. This provides supporting evidence to many educators and parents for the implementation of effective support practices for multicultural adolescents to enhance their school adjustment. Other related implications of these findings and suggestions for future research are also discussed.

Objectives: It is well known that genetic factors and environmental factors play major role in aging skin. In general, son and daughter take after their parents in appearance. But comparability of skin properties in Korean family has not been well estimated. So we evaluated the correlation of skin properties in Korean mother-daughter pairs. Methods: 10 couples of mother and daughter pair(n=20) participate in this study. Mothers and daughters were aged $50.6{\pm}2.459$ and $23.8{\pm}2.15$ years, respectively. Skin moisture, sebum, skin color and elasticity is measured using non-invasive method : Corneometer CM825, Sebumeter(MPA580), Mexameter MX18, Cutometer MPA580. Statistical analysis program we used is Minitab 14 Korea. Results: The Skin moisture of mother group was significantly higher than daughter group. And skin elasticity(R2) of the daughter group was significantly higher than mother group. In the results of correlation analysis between mother and daughter pairs, skin elasticity(R2) had high positive correlation(r=0.729, p=0.026). But skin moisture, sebum, melanin index, erythema index and skin elasticity(R5) did not be confirmed a significant correlation. Conclusions: Skin elasticity(R2) is the only factor that showed high positive correlation significantly in mother and daughter pairs. Mother and daughter share the genetic factors and environmental factors that influence skin aging. So, mother's aging pattern will be a good guide for anti-aging of daughters.

Lectin protein and Kunitz trypsin inhibitor (KTI) protein of mature soybean seed are a main antinutritional factor in soybean seed. The Le gene controls a lectin protein and Ti gene controls the KTI protein in soybean. Ti locus has been located on linkage group 9 in the classical linkage map of soybean. Position of Le locus on linkage map was not identified. Genetic relationship between Ti locus and Le locus could be useful in soybean breeding program for the genetic elimination of these factors. The objective of this study was to determine the independent inheritance or linkage between Ti locus and Le locus in soybean seed. Two $F_2$ populations were developed from three parents (Gaechuck#1, T102, and PI548415). The $F_1$ seeds from Gaechuck#1 (titiLeLe) ${\times}$ T102 (TiTilele) and Gaechuck#1 (titiLeLe) ${\times}$ PI548415 (TiTilele) were obtained. The lectin and KTI protein were analysed from $F_2$ seeds harvested from the $F_1$ plants to find independent assortment or linkage between Ti locus and Le locus. The segregation ratios of 3 : 1 for Le locus (129 Le_ : 44 lele) and Ti locus (132 Ti_ : 41 titi) and were observed. The segregation ratios of 9 : 3 : 3 : 1 (95 Le_Li_ : 34 Le_titi: 37 leleTi_ : 7 leletiti) between Le gene and Ti gene in $F_2$ seeds were observed. This data showed that Ti gene was inherited independently with the Le gene in soybean. These results will be helpful in breeding program for selecting the line with lacking both KTI and lectin protein in soybean.

The aim of this study was to investigate whether there is the relationship between husband support and depression mediated to connubial bliss in Korean married women. A total of 2,120 married women were selected from the database of the Fourth Korea Longitudinal Survey of Women and Families (KLoWF) in 2011-2012. By the structure equation model, among of the husband support, the husband awareness was regarded as the dominant factor related to depression in Korean married women. Then comes couple activity, visiting of parents and division of household labor in that order. This study suggests that husband support significantly associated with connubial bliss and depression in Korean married women. The above findings will help design policy plans to reduce the depression of married women in the nation.
