  • The purpose of this study is to analyze the effect of the parent's socioeconomic status to the academic achievement, together with the mediation effect of the private education expenditure. The structural equation modeling (SEM) method is used with the survey of private education expenditures data collected by Statistics Korea in 2011. In SEM, the multi-group effect is also analyzed for gender, region and school level. The analysis results show that the high socioeconomic status of parent tends to increase the private education expenditures but does not affect the academic achievement, and there are the significant multi-group effect for gender, region, and school level.

  • Previous studies indicate that depression is strongly correlated with suicide, suggesting that individuals with higher levels of depression are more likely to commit suicide. Statistical data, however, show that depression is more prevalent among females whereas suicidal incidents are much higher among males. Using the 1st Seoul Welfare Panel Data, this study aims to examine the association between depression and suicidal attitudes and further examine whether there is gender and age difference in the relationship. Sample consists of 7,396 individuals aged 18 and over. Research questions were answered through the structural equation modeling(SEM) and multi-group SEM. The results showed that (1) depression is significantly associated with suicidal attitudes, replicating the previous findings, (2) the association was much higher among males than females, suggesting that depressed males are more vulnerable to suicide than depressed females, and (3) the gender difference was primarily caused by the group of women aged 65 and over. Based on these findings, implications for theory and practice were discussed.

  • The D&M(DeLone and McLean) IS(Information System) Success model has been widely studied in various criteria such as e-commerce and education, and many empirical research has been performed enough to execute meta-analysis from original model developed in 1992 to updated model in 2003. However, almost all researches have been validated end-user point of view those could lead IS success factors perceived by users but not applicable to developers because developers could not recognize from those result that how much gap exist between one's perception and users. Therefore, in this research, we apply D&M IS success model to A bank developers and users and compare perceptions by multi-group structural equation model.

  • 이 연구는 외국인 노동자들의 한국문화에 대한 적응문제를 살펴 보기 위하여 그들이 한국인들에 대하여 가지고 있는 사회적 거리감(social distance)을 분석하고 있다. 사회적 거리감은 인종 간 상호 관계 연구에서 중요한 개념으로 다루어져 왔으며, 특히 사회적응 수준을 드러내는 효과적인 척도로 각광받아왔다. 이 연구는 한국내 외국인 노동자들의 한국인에 대한 사회적 거리감의 결정요인을 규명하려는 목적을 가지고 있다. 서울과 경기 지역에서 수집된 자료에 대한 다중회귀분석(OLS Regression)을 통하여, 이 연구는 서구 사회에서 다수 인종의 사회적 거리감을 효과적으로 설명하는 것으로 판명된 요인들이 한국의 소수 인종인 외국인노동자들에게도적용될수있는가를살펴본다. 구체적으로는 연령, 성, 교육, 종교, 인종과 같은 사회인구학적 변수들과 한국인과의 접촉정도 가사회적 거리감에 유의미한 효과가 있는지 분석된다. 둘째, 이 연구는 외국인 노동자들의 가장 중요한 삶의 공간인 작업장에서의 경험과 관련된 변수들이 사회적 거리감에 대하여 가지는 효과를 탐구한다. 셋째, 구조방정식 모형(Structural Equation Model)의 적용을 통하여, 이 연구는 다중회귀에서 분석된 여러 설명 변수들 간의 복잡한 인과구조를 규명하고, 이들이 사회적 거리감에 미치는 영향을 직접효과, 간접효과, 전체효과로 나누어 살펴본다. 다중회귀분석 결과는 집단 간 사회적 거리감은 사회인구학적 변수들, 한국인들과의 접촉, 작업장 내 경험등 다양한 요인들의 복합적인 결과물이라는 점을 확인해 준다. 특히 분석결과는 작업장에서의 경험과 느낌이 한국 내 외국인 노동자들의 한국인들에 대한사회적거리감형성에결정적이라는사실을보여주는반면, 기존연구에서 효과적인 것으로 판명된 전통적 요인들은 영향력이 미미하다는 점을 말해준다. 한편, 구조방정식 모형을 적용한 분석결과는 한국인 친구들과의 접촉과 이해하기 쉽고 구체적인 노동조건이 사회적 거리감에 직접적으로 영향을 주고 있다는 것을 보여 준다. 한편 추상적인 노동조건은 사회적 거리감에 간접적으로 영향을 미친다. 상사에 대한 평가와 직무만족은 노동조건에 의해 유의미한 영향을 받지만, 한국인 친구와의 접촉과는 관련이 없다. 간단히 말해, 상사에 대한 평가와 직무만족은 노동조건이 사회적거리감에 대하여 가지는 효과를 매개한다. 결론적으로, 구조방정식모형의 분석결과는 작업장 관련 변수들간에 복잡한 인과구조가 존재한다는 점과 작업장 내 경험이 한국인에 대한 사회적 거리감 형성에 가장 중요하다는점을 확인해 준다.

  • This study aims to examine the level of precariousness among young adults in South Korea and analyze the factors affecting their subjective well-being by adopting the three forms of precariousness suggested by Rodgers(1989) such as lack of resource, uncertainty and disempowerment as its analytical framework. Structural Equation Model was used for analyzing the path model of self-rated health, income level and social support(three forms of resource) affecting subjective wellbeing through uncertainty and disempowerment. Study population include young adults aged between 19 to 34 with a sample size of 415 using data of the 8th wave of the Korean General Social Survey(KGSS), 2010. Study population is divided into lower-age group (aged between 19-26) and upper-age group (aged between 27-34) in order to examine the differences between age groups by using Multiple Group Analysis. Study results show that three forms of resources, uncertainty and disempowerment had direct effect on the subjective well-being of South Korean young adults and disempowerment had the most significant effect among the factors. In addition, self-rated health and income level had indirect effect on subjective well-being through both uncertainty and disempowerment while social support had indirect effect on subjective well-being only through disempowerment. Results from the Multiple Group Analysis indicate that among the two age groups, income level only has a significant effect on subjective well-being in the upper-age group. In addition, disempowerment had greater effect on subjective wellbeing among upper-age group than the lower-age group. Based on the study results, this paper suggested policy implications and discussion for further research.

  • In this study, we explore whether and how the experience of discrimination and social support affects physical health and mental health through disability identity among the disabled aged 50 and over. We also examine such relationship differs by the degree of disability. For the empirical test, we utilized the data from the Panel Survey for the Disabled conducted by our research team in 2016. According to structural equation model analysis, social support has a direct effect on disability identity. It also has a direct effect on physical health. As for the mental health, there are found direct effects of discrimination experience, social support, disability identity, and physical health, Furthermore, social support influences the mental health through disability identity. This finding suggests that social support for the disabled in old age increases disability identity and, in turn, it contributes their mental health. In the meanwhile, multiple group comparison analysis reveals the effect of discrimination experience on disability identity is found for those with lower level of disability but not for their counterparts. This seems to result from that the level of common ground which constitutes disability identity is low for the severely disabled. Thus, it requires our efforts to enhance disability identity focusing on common ground for the severe disabled.

  • 구조방정식모델(Structural Equation Modeling: SEM)은 변수들 간의 인관관계 및 상관관계를 검증하기 위한 통계기법으로 사회학 및 심리학 분야에서 개발되었지만 현재는 경영학, 광고학, 교육학, 생물학, 체육학, 의학, 정치학 등 여러 학문분야에서 광범위하게 사용되고 있다. Amos는 기본적으로 그래픽(Amos graphics)과 베이직(Amos basic)을 제공하기 때문에 정확한 프로그램의 작성이나 행렬에 대한 지식이 없는 초보자들도 아이콘을 이용하여 복잡한 연구모델이나 다중집단분석모델을 분석할 수 있다. PLS(Partial Least Square)는 모형 추정과정에서 발생하는 잔차 또는 예측오차를 최소화하여 예측력을 극대화하기 위한 프로그램이며, 즉, PLS-SEM는 표본 수가 적고 자료가 정규분포를 보이지 않거나 조형지표 모델이거나 복잡한 연구모델 분석에 유용하다. 최근 빅데이터의 열풍으로 자료들을 분석을 위한 도구로 R이 실무 현장에서 인기를 끌고 있다. R은 통계 프로그래밍 언어이자 오픈 소프트웨어 환경으로 통계, 그래픽, 데이터마이닝 등의 다양하고 방대한 양의 패키지들을 지원한다. R에서 제공되는 패키지들이 오픈 소스이고 선형 및 비선형 모델링, 고전적인 통계분석, 시 계열 분석, 분류 및 군집분석 등의 다양한 통계 패키지들을 제공한다는 측면에서 R은 실무는 물론 학문적인 측면에서도, 특히 통계를 기반으로 실증분석을 수행하는 사회과학연구들에서 중요한 역할을 할 수 있을 것으로 기대된다.

  • This study investigated the effects and relationships of various stress, school life adjustment and happiness factors among middle school and high school adolescents. The structural model group effects between boy and girl groups were also investigated. Data was employed from the 'Korean Children and Youth Well-Being Index Survey, 2018' while subjects of the analysis included 5,144 students. Based on the education statistics data, the sample was collected by probability proportional to size. Results utilizing structural equation modeling and multigroup analysis showed that first, school stress, friend stress, and look stress had significant effects on adolescent happiness. School life adjustment had positive significant effects on adolescents' happiness. Parent stress, money stress and school stress had significant effects on school life adjustment. Second, the mediating effect of school life adjustment between stress and happiness was significant with parent, school stress, and financial stress. Third, results of the multi-group analysis by level and gender showed that the structure was similar between boys and girls, with the only differences among mediating effects. Boys had significant mediating effects by school stress, and financial stress, while girls had significant mediating effects by school stress, financial stress, and parent stress. Finally, based on the results of the study, practice and policy implications were suggested to support the promotion of adolescents' happiness.
