본 연구에서는 공적이전소득과 사적이전소득이 노인의 삶의 만족에 영향을 미치는 데 있어 우울과 사회적 지지가 다중매개효과를 가지는가를 규명하고자 한다. 이를 위해 국민노후보장패널조사(KReLS: Korean Retirement & Income Study) 데이터 중 7차 패널자료(2017년도)를 분석에 사용하였으며, 구조방정식모형(structural equation modeling, SEM)을 활용하여 분석을 실시하였다. 분석결과, 첫째, 노인의 공적이전소득이 많을수록 우울 수준은 낮아졌으며, 사회적 지지는 높아졌고, 삶의 만족은 높아지는 것으로 분석되었다. 둘째, 노인의 공적이전소득, 사적이전소득이 삶의 만족에 영향을 미치는데 있어서 우울의 부분매개효과가 검증되었다. 셋째, 노인의 공적이전소득, 사적이전소득이 삶의 만족에 영향을 미치는데 있어서 사회적 지지의 부분매개효과가 검증되었다. 넷째, 노인의 공적이전소득과 사적이전소득이 삶의 만족에 미치는 영향에서 우울과 사회적 지지의 다중매개효과가 유의함이 검증되었다. 이러한 분석결과에 근거해, 노인의 사회적 지지망 강화를 위한 Community Care 사업의 활성화 등의 정책적 제안을 하였다.

The main purpose of this study was to analysis of the structural relationship between early adolescents' social relationships, self esteem, life satisfaction, and school adjustment. Data harvested from the Korean Youth Panel Survey 2010 was analyzed by means of Structural Equation Modeling (SEM). The results indicate that the model is appropriate in terms of goodness of fit and significant path based on the validation procedure. According to the model, the social relationships have some degree of influence upon self esteem which then goes on to have a subsequent effect on life satisfaction; which in turn have a further influence on school adjustment. Social relationships also have a direct influence on life satisfaction, school adjustment, and self esteem has a direct influence on school adjustment. The paper concludes with an outline of the implications of the present study for future studies on this subject.

The purpose of this study was to investigate the degree of sexual behavior. In particular, this study focused on the self-esteem, internet pornography addiction, and relationship satisfaction of freshmen as important predictors of sexual behavior and examined the dynamics of the relationships among the variables. The participants in this research were 1,806 university freshmen: 932 males and 828 females. All respondents submitted their answers on a self-report questionnaire. The data were analyzed with descriptive statistics and Pearson's correlations that used PASW 18.0, and AMOS 18.0, a statistical program for structural equation modeling(SEM), to estimate the hypothesized structural equation model. The major results of this study were as follows: (1) Relationship satisfactions mediated the relationships among self-esteem, internet pornography addiction, and sexual behavior. (2) Sexual behavior between male and female freshmen showed different influences on the test of the structural model invariance across the groups.

Though extensive research has been carried out for the ultimate strength of steel reinforced concrete (SRC) members under static and cyclic load, there was only limited information on the applied analysis models. Modeling of the inelastic response of SRC members can be accomplished by using a microcosmic model. However, generally used microcosmic model, which usually contains a group of parameters, is too complicated to apply in the nonlinear structural computation for large whole buildings. The intent of this paper is to develop an effective modeling approach for the reliable prediction of the inelastic response of SRC columns. Firstly, five SRC columns were tested under cyclic static load and constant axial force. Based on the experimental results, normalized trilinear skeleton curves were then put forward. Theoretical equation of normalizing point (ultimate strength point) was built up according to the load-bearing mechanism of RC columns and verified by the 5 specimens in this test and 14 SRC columns from parallel tests. Since no obvious strength deterioration and pinch effect were observed from the load-displacement curve, hysteresis rule considering only stiffness degradation was proposed through regression analysis. Compared with the experimental results, the applied analysis model is so reasonable to capture the overall cyclic response of SRC columns that it can be easily used in both static and dynamic analysis of the whole SRC structural systems.

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.

The purpose of this study was to develop a model for preschool children's self regulation by examining the effects of maternal parenting variables on preschool children's self regulation. The subjects were 1219 mothers of 4- to 6-year-old preschool children attending kindergarten or child care centers located in Seoul and Kyunggi Province, Korea. For data analysis, exploratory factor analysis(EFA) and confirmatory factor analysis(CFA) were applied to the survey data in the first phase and structural equation modeling(SEM) analysis in the second phase. The major results of this study were as follows: maternal parenting stress and maternal behavior were the most direct influential variables on preschool children's self-regulation. Moreover, maternal parenting efficacy was indirectly mediated through maternal behavior.

The ubiquitous technology, leading the stream of change in telecommunication market, makes VoIP a foundation technology to enter NGN era. With this trend in mind, VoIP providers try to satisfy customer needs and invest on R&D in order to survive in this emerging market. The critical issues to VoIP providers are two fold the first one is to find out the quality attributes of Internet telephony service; and the second one is to assess the impact they have on customer satisfaction, customer loyalty and customer performance. In this study, we attempt to empirically answer the above two issues employing SEM (structural equation modeling) and AHP (analytic hierarchy process), and suggest strategic guidelines for successful deployment of Internet telephony service.

The purpose of this research is to identify the factors of self-determination theory (e.g., autonomy, competence, and relatedness) affecting flow, satisfaction, and loyalty. This research uses structural equation modeling (SEM) to confirm the validity and analyzes the causal relationship of the suggested model. The results indicate that competence and relatedness positively influence flow and that autonomy positively influences satisfaction. First, autonomy is significantly shown to influences satisfaction and does not significantly influence flow. Second, that competence significantly influenced flow and indirectly influenced satisfaction. Third, relatedness significantly influenced flow and indirectly influenced satisfaction. Finally, flow influenced satisfaction, and flow and satisfaction directly and indirectly influenced loyalty.

The purpose of this study was to examine the effect of perceived justice associated with service recovery on perceived service quality, and the relationships among perceived service quality, customer satisfaction and behavioral intentions in online apparel shopping contexts. Justice theory provided the theoretical framework for this study. The research strategy employed an online survey methodology. Online shoppers (N=669) who had experiences in service failure and dissatisfactions completed a questionnaire. The model of the study was tested by structural equation modeling (SEM) and the results of SEM revealed positive effect of perceived justice regarding service recovery on perceived service quality, positive effect of perceived service quality on customer satisfaction, and positive effect of customer satisfaction on behavioral intention. The results of this study have implications for online retailers. Online retailers need to understand the importance of service recovery by which service failures are managed.
