The purpose of this study is to explore the structural relationships among parents' educational involvement and parental efficacy on students' school life satisfaction and school achievement and to determine whether there are any differences depending on family type and school level. Using data from 2,497 families that participated in the 2018 National Survey on Children's Life, t-tests and structural equation modeling were conducted. The results of this study demonstrated that two-parent families reported higher levels of educational involvement than single-parent families and custodial grandparent families. Also, two-parent families raising children in elementary schools showed higher educational involvement than two-parent families raising children attending middle schools. Second, parental efficacy was found to mediate the effects of parents' educational involvement on students' school life satisfaction and school achievement. Third, the path coefficients between parents' educational involvement, students' school life satisfaction, and school achievement showed statistically significant differences depending on family type, with two-parent families having greater involvement than single-parent families and custodial grandparent families. Fourth, multiple group analysis reported a statistically significant difference in the relationship between parents' educational involvement and school achievement as well as parental efficacy and school achievement depending on the school level.

The purpose of this study is to investigate the economic deprivation of male-headed or female-headed households. Household having children under the age of 18 are categorized into three types according to the gender of household head: male-headed household, female-headed household, and dual-parents household. The findings from data, for this study came from the Korean Labor Panel Study in 2003. The analysis shows that the household's age, education, residence types, etc are key explanatory variables in determining whether to be in poverty. While the public income transfer is most effective in reducing poverty in female-headed households, the private income source is relatively more useful among male-headed families. Since single-household families are particularly at risk, public policy makers should pay special attentions to developing and expanding welfare-to-work programs which provides work incentives to overcome relative poverty and community networks on child care.

Purpose: This study was done to compare factors influencing children's self-esteem between two parent families and single parent families. Methods: The participants were 692 children aged 11 to 13 yr (388 in two parent families and 304 in single parent families) recruited from 20 community agencies and 5 elementary schools in Gyeonggi Province and Seoul City, South Korea. Data were collected from May to July, 2007 using a survey questionnaire containing items on self-esteem, internal control, problematic behavior, school record, family hardiness, parent-child communication and social support. The data were analyzed using SPSS 15.0 program and factors affecting children's self-esteem were analyzed by stepwise multiple regression. Results: Scores for the study variables were significantly different between the two groups. The factors influencing children's self-esteem were also different according to family type. For two parent families, internal control, problematic behavior, school record, and parent-child communication significantly predicted the level of self-esteem (adjusted $R^2$=.505, p<.001). For single parent families, social support, family hardiness, internal control, problematic behavior, school record, and parent-child communication significantly predicted the level of self-esteem (adjusted $R^2$=.444, p<.001). Conclusion: Nurse working with children should consider family type-specific factors influencing their self-esteem.

The purpose of this study was to examine effects of socio-demographic, health, and delinquent behavior factors on internet addiction among the Korean youth. This study used the 2009 Korean Youth Health Risk Behavior On-line Survey data. It selected 73,238 cases of junior and senior high school students from the raw data and conducted a secondary data analysis. Frequency analysis, chi-square test and logistic regression analysis was conducted. Being male, living without parents, low economic status, poor academic record, poor subjective health status, poor subjective well-being, high level of stress, presence of depression and experience of drug use significantly increased likelihood of internet addiction. Findings may be used for developing strategies to deal with internet addiction among adolescents in Korea.

최근 우리 나라도 자동차의 수요가 급격히 늘어나고 있고, 생산량도 급증하 고 있어 자동차 공업이 산업의 최고의 위치를 확보하게 되었다. 자동차는 최 신 종합 기계 구조물로서 전기, 전자, 제어에 이르기까지 거의 모든 분양의 학문적 이론과 기술을 도입하는 최첨단의 기계 장비인것이다. 따라서 그 부 가가치 또한 매우 큰 것이다. 자동차의 성능을 결정짓는 가장 커다란 요소는 주행 성능과 안정성 및 조종성이다. 주행성능이라 함은 자동차의 종방향 운 동에 관한 성능으로서 기관의 동력에 지배적인 영향을 받는 성능(동력 성능) 과 그 밖의 성능(타향 성능, 제동 성능)으로 구분된다. 또 안정성과 조종성이 라함은 자동차의 횡방향 운동에 관한 성능으로서 로울링과 요우잉을 포함시 킨 곡선 운동에 관한 성능을 일컫는다. 이러한 운동 성능을 좌우하는 것은 구조적인 설계의 양부와 스프링이나 댐퍼의 성능일 것이다. 자동차의 수많은 부품 중의 다수가 국산화 되어 있지 아니하고, 또한 이러한 부품들의 성능을 시험할 수 있는 장비의 수입 의존도가 높은 것은 업계나 학계 등에서 앞으 로 많은 연구가 이루어져야 할 점이다. 자동차의 충격 흡수기(shock absorber)의 검사기도 또한 수입 시험기에 의존하고 있었던 것이 현실이었 다. 이에 본 연구진은 이 검사기의 국산화에 착수 한 것이다. 자동차에 있어 서 충격 흡수기는 지면에서 오는 충격을 급속히 흡수하는 역할을 하여 자동 차의 주행 성능과 안정성을 높혀 주며, 승차감을 높혀 주는 중요한 부품이 다. 따라서 충격 흡수기의 양부의 판정은 대단히 중요한 것이다. 본 연구에 서는 충격 흡수기의 충격 흡수력(감쇠력)을 측정하여 감쇠 특성을 정도 높게 파악할 수 있는 시험기를 만드는데 그 목적을 두고 있다. 연구는 시험기의 구동부를 제작하는 기계부와, 제어 및 계측의 하드웨어를 담당하는 전기.전 자부및 실제로 기계를 구동, 제어하고 측정 결과를 기록하고 출력하는 부분 을 담당하는 소프트웨어 개발부로 나누어서 진행하였다.

This study was conducted to determine family factors related to obesity of high school students. A descriptive correlational study was conducted with 384 high school students in I metropolitan city. Data were collected from February to April of 2015 using self-report structured questionnaires. Questionnaires included weight, height, individual characteristics of subjects and their familial characteristics. Collected data were analyzed by multiple logistic regression. Logistic regression analysis revealed that male gender (aOR = 4.37; 95% CI [1.26, 15.16]), having a non-regular paternal job (aOR = 3.10; 95% CI [1.15, 8.40]), and not being in a two parent family (aOR = 3.52; 95% CI [1.29, 9.61]) were statistically significant contributors to obesity. These results indicate that it is necessary to improve social awareness regarding the obesity risk of male adolescents. Health care providers should recognize the importance of family factors such as parental socioeconomic status and family structures.
