최근 에어비앤비나 우버와 같은 협력적 소비 기반의 비즈니스모델을 가진 공유경제가 성장하고 있다. 본 논문은 공유경제에 대한 개념을 정의하고, 이용의도에 미치는 영향을 분석하였다. 본 논문은 경제적, 기능적, 경험적, 사회적 가치를 포함한 4가지 지각된 가치와 주관적 규범, 이미지, 사회적 임계점을 구성하는 3가지 사회적 영향이 공유경제 이용의도에 미치는 영향을 알아보고 신뢰와 사회적 규범, 네트워크와 사회구조를 포함한 사회적자본의 조절효과에 관심을 두고 있다. 가설을 검증하고자 온라인과 오프라인에서 설문조사를 실시하였고, 지각된 가치와 사회적 영향이 공유경제 이용의도에 미치는 영향을 알아보고자 변수별로 다중회귀분석을 실시하였다. 또한 사회적자본의 조절효과를 알아보기 위하여 위계적인 회귀분석을 실시하였다. 다중회귀분석 결과는 다음과 같다. 지각된 가치 중 경제적, 경험적 가치는 공유경제 이용의도에 영향을 미치는 것으로 나타났다. 위계적인 회귀분석의 결과에서 사회적자본은 지각된 가치와 사회적 영향의 공유경제 이용의도 관계에 있어 조절적인 영향을 미치는 것으로 나타났다. 본 연구는 지각된 가치를 통합적 분석, 기존 공유경제 연구에서 자주 다뤄지지 않았던 사회적 영향과 사회적자본의 요인을 다룬 점에 의미가 있지만, 설문조사 결과의 한계가 있었기에 향후 새로운 연구 방향성을 제시할 수 있다.

우울은 군대 내 발생되는 극단적인 사고 중 하나인 자살의 주요 원인으로 제시되어 왔다. 본 연구는 군인들의 우울, 불안 및 자아존중감의 수준을 파악하고, 우울의 영향요인을 탐색하고 이들을 예측하는데 주로 사용해 왔던 다중회귀분석 방법과 효과적인 의사결정방법으로 알려진 회귀나무모형의 효과성을 비교해보고자 하였다. 방법: 횡단적 조사연구이며, 우울측정에는 CES-D, 불안측정은 SAI, 자아존중감은 Rosenberg(1965)의 도구를 사용하였다. 연구대상자는 강원도 전방 부대 근무 중인 군인이며, 534부가 회수되었다. SPSS/WIN 18.0을 이용하여 위계적 다중회귀분석과 회귀나무모형을 실시하였다. 결과: 대상자들의 우울, 불안 및 자아존중감의 정도는 각각 $10.7({\pm}9.8)$, $38.5({\pm}10.2)$과 $31.7({\pm}5.2)$이었다. 대상자의 23.6%(126명)가 경한 우울을 나타내었다. 다중회귀분석에 의한 우울 영향요인은 불안, 자아존중감과 복무기간이었으며, 우울에 대하여 62.0%의 설명력을 가지고 있었다. 또한 회귀나무모형에서는 높은 불안과 불안이 다소 낮더라도 전역 후 진로가 불확실한 집단이 우울 위험군일 것으로 예측되었다. 결론: 본 연구 대상자들의 우울의 주요 영향요인은 불안으로 나타났다. 군대 내에서 적용할 수 있는 불안 조절 방법 개발이 필요할 것으로 보인다. 또한 일부 요인에서 차이가 있어, 반복 연구가 필요하지만, 주요 변인인 불안을 예측했다는 점에서 보면 다중회귀분석과 회귀나무모형은 군인들의 우울을 예측에 유용한 방법으로 보인다.

목적: 본 연구의 목적은 대학원 또는 RN-BSN과정에 등록하여 학업을 계속하는 간호사들이 학업과 직업, 가정에서 다양한 역할을 수행하면서 발생하는 역할갈등과 역할관련 스트레스의 관련성을 파악하는 것이다. 연구방법: 국내4개 간호대학 RN-BSN과정 또는 대학원에서 수업을 받고 있는 간호사 149명을 대상으로 역할갈등, 역할스트레스를 측정하였다. 수집된 자료는 SPSS WIN 18.0 프로그램을 이용하여 분석하였으며 서술통계, 빈도분석, 상관관계분석과 함께 위계적 다중회귀분석을 이용하였다. 연구결과: 연구대상자의 work-school to family 갈등은 평균 $2.77{\pm}0.93$점, family-school to work 갈등은 $3.27{\pm}0.77$점, family-work to school에 대한 역할갈등은 $3.08{\pm}0.83$점이었다. 역할관련 스트레스는 평균 $5.99{\pm}1.66$점이었으며, 스트레스의 하위영역 중 가정스트레스 $4.77{\pm}2.62$점, 직장스트레스 $6.66{\pm}2.12$점, 학업스트레스 $6.84{\pm}1.87$점이었다. 위계적 다중회귀분석 중에서 직위가 스트레스변인의 2%를 설명하였고, 2단계에서 갈등요인 3변수가 추가 입력되었을 때 스트레스 변인의 23%를 설명하는 것으로 나타났다. 결론: 학업과 근무, 가정으로부터 다양한 역할을 수행하는 간호사는 다양한 역할에서 오는 갈등과 스트레스의 연관성이 확인되었으므로, 이를 근거로 업무만족과 성취를 높일 수 있는 정책이 개발되어야 한다.

The purpose of this descriptive research is to get basic data for educational program after investigating convergent effect of psychological capital on learning satisfaction of nursing freshmen. Using SPSS 21, T-test, ANOVA, Pearson's correlation coefficient and hierarchical multiple regression of the 164 collected data were carried out. The mean scores of psychological capital and learning satisfaction were above the middle, and the 'hope' was the highest among subdomains of psychological capital. There was a positive correlation between psychological capital and learning satisfaction(r=.665, p<.001). School performance(${\beta}=.311$), school life satisfaction(${\beta}=.191$) and psychological capital(${\beta}=.522$) were the significant factors of learning satisfaction in hierarchical multiple regression(F=37.651, p=.004). The explanatory rate of variables on learning satisfaction was 57.4%. It is needed applying these results in developing learning satisfaction programs, but it isn't appropriate to generalize these results conducted on nursing freshmen in one university.

This study aims to analyze whether both childcare subsidy and childcare leave policies have moderating effects on the relationship between Korean women's value of children and their intentions for subsequent childbirth. The data are used from the 2015 National Survey on Fertility and Family Health and Welfare. Both hierarchical multiple regression analysis and moderated regression analysis are used for statistical analysis. The findings from the study are as follow. First, the ideal number of children, instrumental values, and emotional values have positive effects on the intentions for subsequent childbirth after controlling for background variables(level of education, income, age, and number of children). Second, childcare leave policy has no significant effect on the intentions for subsequent childbirth while childcare subsidy policy has the negative effect. Third, only childcare subsidy policy has moderating effects on the relationship between instrumental, emotional values, and the intentions for subsequent childbirth. These results suggest that policies enhancing the value of children should be implemented in addition to traditional birth rate policies. Furthermore, new birth rate polices are needed for those married women who have a high possibility of subsequent childbirth.

The Effects of Social Capital on Occupational Aspiration in University Students This study aims to understand the impact of social capital (parent-child relationship, human network, and SNS use) on the occupational aspiration level in university students based on Coleman's Social Capital Concept. To achieve this, statistical significance test was conducted through correlation analysis and hierarchical multiple regression analysis. The major study findings are as follows. As a result of correlation analysis, it was found that Other variables, except for parent's occupational of social capital had a positive effect on vocational aspiration. Also. as a result of hierarchical multiple regression analysis, it was found that parent-child relationship, human network obtained from social activities, Social Networking Service use and usefulness of information - social capital factors - had a statistically significant impact on occupational aspiration. Such findings suggest that the process of possessing and acquiring social capital among university students served as an important achievement-oriented value in terms of social mobility.

In this paper, we analyzed wage determinants of the vocational high school graduates utilizing both individual-level and work region-level variables. We formulate the models in the way wage determination has multi-level structure in the sense that individual wage is influenced by individual-level variables (level-1) and work region-level (level-2) variables. To incorporate dependency between individual wages into the model, we utilize hierarchical linear model (HLM). The major results are as follows. First, it is shown that the HLM model is better than the OLS regression models which do not take level-1 and level-2 variables simultaneously into account. Second, random effects on sex, maester dummy and engineering dummy variables are statistically significant. Third, the fixed effects on business hours and mean wage of regular job for level-2 variables are statistically significant effect individual-level wages. Finally, parental education level, parental income, number of licenses and high school grade are statistically significant for higher individual-level wages.
