The primary purpose of this study was to examine to what extent adolescents’ daily self-evaluation mediates the effect of experiencing intimacy in parent-adolescent interactions on positive peer interactions the next day, even after controlling for gender and grade level. We employed a daily diary method for seven days in a sample of 452 Korean adolescents, collecting checklist data at the end of each day. Data were analyzed by using hierarchical linear modeling. According to moderated multilevel mediation analyses, the variance of self-evaluation explained 83% of the variance in the lagged effect of parental intimacy on the next day peer interaction even after the upper-level effects of gender and grade level were accounted for. Forth graders were more likely than 7th graders to have a more positive view of themselves when they experienced parental intimacy the previous day. Girls were less likely to experience positive peer interactions when they perceived less intimacy with their parents the day before. Results suggested that it would be most effective for peer relationship programs to teach parents and adolescents how to experience intimacy in their daily interactions, particularly in ways that help adolescents to think more positively about themselves. It would be helpful for parents to learn about various ways to compliment and encourage the adolescent child in everyday conversations. Lastly, findings in grade level differences also suggest that these programs might be especially effective for 4th graders more than 7th graders.

The rhizome of Curcuma longa (turmeric) is often used in Asia as a spice and as a medicine. Its most wellstudied component, curcumin, has been shown to exhibit poor bioavailability in animal studies and clinical trials. We hypothesized that the presence of lipophilic components (e.g., turmerones) in turmeric extract would affect the absorption of curcumin. The effects of turmerones on curcumin transport were evaluated in human intestinal epithelial Caco-2 cells. The roles of turmerones on P-glycoprotein (P-gp) activities and mRNA expression were also evaluated. Results showed that in the presence of a- and aromatic turmerones, the amount of curcumin transported into the Caco-2 cells in 2 hours was significantly increased. a-Turmerone and verapamil (a P-gp inhibitor) significantly inhibited the efflux of rhodamine-123 and digoxin (i.e.,inhibited the activity of P-gp). It is interesting that aromatic turmerone significantly increased the rhodamine-123 efflux and Pgp (MDR1 gene) mRNA expression levels. The effects of a- and aromatic turmerones on curcumin transport as well as P-gp activities were shown here for the first time. The presence of turmerones did affect the absorption of curcumin in vitro. These findings suggest the potential use of turmeric extract (including curcumin and turmerones), rather than curcumin alone, for treating diseases.

청소년들은 어떤 날 더 행복한가?: 부모와의 친밀감이 일상의 행복감에 미치는 영향 및 가구소득과 학교 급에 따른 차이

Previous research on adolescent happiness has employed cross-sectional designs and overlooked day-to-day variability in happiness. On the basis of dynamic nature of parent-child interaction and affective experience during adolescence, this study used a daily diary method to examine whether daily intimacy with parents predicted happiness on the same day and the following day in a sample of 452 adolescents across seven days. Participants completed a questionnaire first and then responded to a daily diary checklist each night for seven days. Specifically, this study examined individual differences in daily associations by assessing whether monthly household income, school level, and gender moderated the effect of daily intimacy with parents on daily happiness. For data analysis, this study used a two-level hierarchical linear modeling. Results showed that adolescents were happier on days in which they experienced intimacy with parents and this effect lingered until the next day. In addition, adolescents from families with a monthly household income of 5,000,000won or more were significantly happier on days when they experienced greater intimacy with parents, whereas the magnitude of increase in happiness as a function of intimacy with parents was smaller for adolescents from families with a monthly household income of 3,000,000won. Further, the effect of intimacy with parents on the next day happiness was significantly greater for 7th graders than 4th graders. No gender difference was found. This study showed that intimacy with parents is a powerful experience, which has significant consequences for happiness in adolescents’ daily lives, particularly among 7th graders and adolescents from families that are financially well-off. Based on the results, we recommended programs designed to enhance parent-child intimacy, particularly for families with 7th graders. In addition, we recommended that practitioners first identify patterns of parent-child relational dynamics in each income group and design customized programs accordingly.

Objective: This study aims to validate the Korean version of Familial Ethnic Socialization Measure (K-FESM) for 5th and 6th grade multicultural adolescents of marriage migrant mothers from China and Vietnam in Korea. Method: The sample was 358 adolescents who have Korean fathers and marriage migrant mothers (mother’s country of origin: 157 Vietnam, 105 China, 56 Philippines, 40 Japan). The original FESM has 12 items but in K-FESM 3 items were replaced in consideration of unique characteristics of multicultural families in Korea. Analyses including internal consistency analyses, principal-component, exploratory and confirmatory factor analyses, and criterion-related validity tests were conducted for 4 groups by the country of origin of participants’ mothers. Results: The results of internal consistency were good for each group. Adolescents with marriage migrant mothers from Philippines and Japan, however, were found to be inappropriate for factor analyses. Factor analyses showed that the one-factor model was suitable for adolescents of marriage migrant mothers from Vietnam and China separately. Criterion-related validity test using correlations between familial ethnic socialization and ethnic affirmation/belonging confirmed the validity of K-FESM. Conclusions: The Korean version of FESM was found to be a reliable and valid tool for measuring ethnic socialization for multicultural adolescents of marriage migrant mothers in Korea. Using K-FESM, research on adolescents in multicultural families could be expanded and improved.

빈곤관련 위험요인의 잠재계층유형이 청소년 건강증진행위에 미치는 영향
이상균(Lee, Sanggyun),유조안(Yoo, Joan P),그레이스정(Chung, Grace H) 한국청소년정책연구원 2015 한국청소년연구 Vol.26 No.3
본 연구는 빈곤관련 위험요인의 잠재계층유형이 건강증진모형에 기반한 매개변인을 통해 청소년 건강증진행위에 영향을 미치는 매개효과를 확인하였다. 2014년 서울시교육청의 협조아래 수집된 서울교육건강복지패널 1차년도 자료를 분석하였다. 분석자료는 학부모의 연구참여 동의를 얻은 초등학생·중학생 820명과 그들의 주양육자 820명이 응답한 자료다. 최저생계비 미달과 정부지원·보조 경험으로 구성된 소득빈곤, 가족구조결손을 보여주는 한부모가구, 의료욕구 미충족, 경제적 어려움, 식품불안정성 등 빈곤관련 위험요인에 대해 잠재계층분석을 실시한 결과, ‘비빈곤집단’ ,‘소득비빈곤·물질적 결핍집단’, ‘한부모빈곤·물질적 결핍집단’으로 명명된 3개 잠재계층유형으로 분류되었다. 이들 유형이 방임경험, 가족활동, 자기효능감, 스트레스를 통해 청소년의 건강증진행위에 영향을 미치는지 매개효과분석을 수행하였다. 분석결과, 소득비빈곤·물질적 결핍집단과 한부모빈곤·물질적 결핍집단은 비빈곤집단에 비해 방임경험을 제외한 모든 매개변인을 통해 건강증진행위에 부정적인 영향을 미치는 것으로 확인되었다. 소득빈곤을 경험하는 전형적인 취약집단과 함께 소득빈곤을 경험하지 않는 가구에서도 복수의 빈곤관련 위험요인을 경험하는 경우, 가족활동, 자기효능감, 스트레스를 통해 건강증진행위에 부정적인 영향을 미치는 것으로 나타났다. 이는 청소년 건강증진과 관련하여 빈곤관련 위험요인의 누적효과와 하위집단유형을 고려해 개입대상을 선택할 필요성이 있음을 보여준다. 이러한 분석결과에 기반하여 청소년기 건강증진행위를 향상시키기 위한 정책적, 실천적 제언과 함의를 논의하였다. The purpose of this study is to identify the underlying typology of poverty-related risks of households with adolescents, and to examine whether significant differences in adolescents’ health promoting behaviors are observed between these discrete groups. Latent class analysis was utilized to estimate the latent classes of poverty-related risks. Mediation analysis with multicategorical independent variable was employed to examine the mediating effects of proposed mediators of the relationship between the latent classes and adolescents’ health promoting behaviors. The proposed mediators include neglect experiences, family activities, and adolescent’s self-efficacy and stress. Our analytic results showed three latent classes of poverty-related risks including ‘single-parent poverty?material hardship group’, ‘non income poverty?material hardship group’, and ‘no economic hardship group’. Relative to the ‘no economic hardship group’, those assigned to 2 poverty-related hardship groups were less likely to have heath promoting behaviors through the proposed mediators(except for neglect experiences). Based on these findings, health promotion and intervention programs for adolescents will need to consider this clear heterogeneity of poverty-related risks and enhance the level of attention given to significant mediators on the subpopulation. The implications of the study findings and suggestions for future research are also discussed.
