This study compared the individual, family, environmental factors, and subjective sleep sufficiency according to gender among Korean adolescents and to examine relevance among the individual, family, environmental factors, and subjective sleep sufficiency. The subjects were 65,528 Korean adolescents(male: 33,803, female: 31,725), who were derived from the 12th Korea Youth Risk Behavior Web-based Survey 2016 in South Korea. As a result, the prevalence of the subjective sleep sufficiency in this study was 33.4% male and 19.5% female. The subjective sleep sufficiency was affected by the depression experience, suicidal ideation, school achievement, feeling of stress, feeling of happiness, subjective health status, alcohol experience, smoking experience, substance experience, allergic rhinitis, and atopic dermatitis in individual factors; economic status, educational level of parents and living arrangement in family factors; school grade, school type and emotional support in environmental factors in both males and females. In individual factors, breakfast eating and asthma affected the male's subjective sleep sufficiency and physical activity affected the female's. The mental health of the individual factors was the most influential factor in adolescent's subjective sleep sufficiency. Therefore, nursing intervention to improve Korean adolescent's subjective sleep sufficiency should be applied considering gender differences.

The purpose of this study was to compare the degree of happiness between mothers of preschoolers (3-5yrs) and mothers of elementary school students (6-7yrs). The subjects of this study included 168 mothers of preschoolers and 170 mothers of elementary school students. They were randomly chosen. We measured and analyzed 338 mothers' happiness using Ryff's psychological well-being items. The results of this study reveal that although overall happiness level was similar, the two groups of mothers' happiness had statistically significant differences in 6 factors of mothers' happiness. Preschooler mothers had higher levels of happiness in autonomy and personal growth, while elementary school student mothers had higher levels of happiness in environment mastery, positive relationships, purpose of life, and self-acceptance. Also, the background of mothers, such as age, educational status, family income, and religion caused statistically significant differences in happiness level of both groups.

This study is analysing the factors determining individuals' behavior of selecting self-employment not only at the micro-level but also at the macro-level to put a particular emphasis on the financial constraint and unemployment rate representing business cycle. The data used in this study are "Korean Labor and Income Panal Study" of the Korea Labor Institute and "Economically Active Population Survey" of National Statistical Office. The main findings are as follows. First, human capital such as educational attainment and job experience has positive effects on male's selection of self-employment. The effects of job experience, however, changed negative for female's selection of self-employment. Second, real estate is significantly enhancing the selection probabilities of employer selection while the income from financial assets has negative effects. Third, entrepreneurial culture and environment are also raising the self-employment selection probability. Lastly, the regional unemployment rate representing the business cycle has positive effects on the self-employment selection after the financial crisis in 1997 both at the micro and macro level. Moreover, the coefficient of regional unemployment rate has changed positive in the structural model of self-employment selection controlling for selection bias and income opportunities, which means that individual's behavior of self-employment selection is rather complex when accounting for the uncertainties of income opportunities and diverse characteristics of self-employment workforce.

As the result of the survey of the recognition on aptitude and job understanding level, there appeared some meaningful differences by the school background on whether or not currently to make efforts to get a better job. In the matter of the pride as to the child welfare teachers dispatched, 27.5% of opinion givers had a clear mission and an objective sense about a current job, and the child welfare teachers dispatched recognized that they felt pleasure and value through the education of students.

The purpose of this study is to investigate the effects of the educational context variables on students' science achievement and interest in TIMSS 2015. TIMSS 2015 science data and questionnaire results were used to fit the Hierarchical Linear Model (HLM) in this study. According to the results, books at home, parents' level of education, and students' views on science lessons have significant influence on science achievement of above-high level 4th-grade students, and books at home on below-intermediate level 4th-grade students. Books at home, students' views on science lessons, and school composition by student economic background have significant influence on science achievement of above-high level 8th-grade students, and books at home and students' views on science lessons on science achievement of below-Intermediate level 8th-grade students. In all grade levels, books at home, and students' views on science lessons have significant influence on science achievement and interest. Discussed in the conclusion are ways to improve science teaching and learning including offering systematic reading programs for all students, reinforcement of student-participation in science classes, connecting science hands-on activities with science concepts for below-Intermediate level elementary students, and so on.

The purpose of this study is to investigate the effects of educational context variables on achievement and interest in mathematics in high and low achieving students in Korea. Students participated in TIMSS 2015 in Korea were divided into two groups according to their achievement in mathematics. And the effects of educational context variables on achievement and interest in mathematics were analyzed in each group using the Hierarchical Linear Model(HLM). Main findings of this study are as follows. First, variables which influence achievement also influence interest but any variables which influence interest don't influence achievement in upper-group students. Number of Books and Students' Perceived Mathematics Lessons have strong influence on achievement and interest in both fourth and eighth grade students. Second, variables which influence achievement or interest in mathematics in lower-group also influence achievement or interest in mathematics in upper-group students. But any variables which influence achievement or interest in upper-group students don't influence achievement or interest in lower-group students. For examples, Parents' Education, Students' Perceived Mathematics Lessons have effects on upper-group students' achievement. Number of Books, Home Learning Environment, and Numeracy Activities Before School have significant effects on the achievement of fourth grade students. Students' Perceived Mathematics Lessons is the variable that influence on the interest of both fourth grade and eighth grade students. This study suggests the ways to improve mathematics teaching and learning based on these results.

In this study, we analyzed the longitudinal effect of participation in an overseas exchange student program on foreign language competence, intercultural competence, and personal development. Data were collected over three time points from the pre-, post-, and post-post tests with Korean college students who participated in an overseas exchange program. Hierarchical linear model was conducted to examine whether the change of participation effects exists over time and which predictors affected outcomes. The results of unconditional growth model showed that foreign language competence, cultural competence, and personal development showed statistically significant differences in their initial status prior to departure to participate in an overseas program as well as their growth rate. The results of conditional growth model showed that parents' level of education and overseas experiences before college affected the initial status of foreign language competence, and gender and overseas experience before college affected those of cultural competence as well as personal development. In case of growth rate, overseas experience before college and destination country/region affected foreign language competence, and interactions between Korean participating students and local students affected cultural competence. For personal development, only overseas experiences before college affected its growth rate. Lastly, relevant discussion and implications were provided.
