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.

The purpose of this study is to evaluate the actual conditions of peer victimization and to examine how the various factors of school climate influence peer victimization. Analysis on the relationship between various school climate and peer victimization has not been yet dealt with in Korea. Participants in this study were middle school students chosen from 11 middle schools in Seoul, by convenience sampling. A total of 1,204 surveys were then analyzed. Methods for analysis included Frequencies, Descriptives, Pearson's Correlation, Hierarchical Regression. From the result of the analysis, the level of verbal violence came out to be a relatively high form of peer victimization. The hierarchical regression were conducted in two steps. The second model's descriptive variable was higher by 19.6% than the first model. The variables of interaction between teacher and student in peer violence(${\beta}=.130$), of school facility maintenance(${\beta}=.067$), of safety of school environment(${\beta}=.331$), and economic status and sex out of controlled variables were proved to be of significance, and those variables explained 23.0% of the entire model. Based on the results of this study, practical and effective policy solutions to improve the school climate better have been suggested.

Recently, There has been an increasing of utilization IT, and studies have been conducted on predicting learning results. In this study, Learning activity data were collected that could affect learning outcomes by using learning analysis. The survey was conducted at a university in South Chung-Cheong Province from October to December 2018, with 1,062 students taking part in the survey. First, A Hierarchical regression analysis was conducted by organizing a model of individual, academic, and behavioral factors for learning results to ensure the validity of predictors in machine learning. The model of hierarchical regression was significant, and the explanatory power (R²) was shown to increase step by step, so the variables injected were appropriate. In addition, The linear regression analysis method of machine learning was used to determine how predictable learning outcomes are, and its error rate was collected at about 8.4%.

본 연구에서는 TOD는 대중교통수단의 분담율 제고가 목적인데 이를 위한 정책대안의 모색에 필요한 새로운 분석기법을 제시하였다. 교통수단의 결정요인은 개인 특성과 라이프스타일 그리고 도시공간특성인데 이 요인들은 상호의존적으로 복합적 결합작용은 한다. 또한 개인과 그룹 및 지역 특성은 서로 다른 차원에서 상호의존성을 갖는다. 전통적 회귀분석과는 달리 위계적 분석모형은 요인들 간의 상호의존성과 복합결합적 영향관계를 규명하는 장점이 있다. 이러한 분석 기법에 의한 결과는 보다 효율적인 TOD정책 대한의 모색에 많은 기여를 할 것으로 기대된다.

In this study, a new analytical techniques is proposed for seeking policy alternatives aimed at objectives of TDM, increasing the transit rideshare. Determinants of travel mode such as personal characteristics, lifestyle, and urban spatial characteristics are interdependent and have combined effect on decision. In addition, individuals, groups, and regional characteristics have interdependencies at different levels. Unlike traditional regression analysis, hierarchical analysis model has the advantage of identifying interdependencies and complex relationship between the combined impact factors. This analysis technique is expected to be a significant contribution to seek a more efficient TOD policy.

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.

This study was designed to investigate the differences in the mediation effects of cognitive emotion-regulation in the relationships between family stress and marital satisfaction of middle-aged husbands and wives. The data were underwent through the SPSS 19. Win for frequency, paired-t-test, multiple regression analysis, and for the further analysis of hiearchical multiple regression and the analysis for the mediation effect proposed by Baron & Kenny(1996) and Sobel test(Sobel, 1982). The results were as follows. First, hiearchical multiple regression analysis showed that education level, couples' problems, replanning strategies were proved to be significant for the marital satisfaction of the husbands, while age, couples' problems, acceptance strategies were significant for the marital satisfaction of the wives. Second, cognitive emotion-regulation strategies were proved to partially mediate in the relationship between family stress and marital satisfaction. The limitations of the study and implications for the further research were discussed based on the results.

이 연구의 목적은 민간경비원의 조직문화와 직무스트레스 및 조직몰입의 관계를 규명하는데 있다. 이 연구는 2011년 수도권소재(인천) 공항에서 재직하고 있는 민간경비원들을 모집단으로 설정한 후 유의표집법을 이용하여 최종분석에 이용된 사례 수는 총 203명이다. 연구에 사용된 설문지는 총 56문항으로 구성되었다. 분석방법은 SPSSWIN 18.0을 이용하여 빈도분석, 요인분석, 신뢰도분석, 회귀분석 등을 실시하였다. 설문지의 신뢰도는 Cronbach's ${\alpha}$값이 .671이상으로 나타났다. 결론은 다음과 같다. 첫째, 민간경비원의 조직문화는 직무스트레스에 영향을 미친다. 즉, 개발적, 위계적 문화가 형성 되지 않는다면, 보상경력개발에 대한 직무스트레스는 증가한다. 반면, 개발적, 합의적 문화가 형성 되면, 직무특성, 인간관계, 역할과 관련된 직무스트레스는 감소한다. 둘째, 민간경비원의 조직문화는 조직몰입에 영향을 미친다. 즉, 개발적, 위계적 문화가 형성 되면, 정서적, 근속적, 규범적 몰입은 높아진다. 셋째, 민간경비원의 직무스트레스는 조직몰입에 영향을 미친다. 즉, 보상경력개발이 불공정하게 이루어질수록 정서적, 근속적 규범적 몰입은 낮아진다. 반면, 현재 자신의 직무가 능동적으로 이루어진다면, 정서적, 근속적, 규범적 몰입은 높아진다.

The purpose of this study was to empirically analyze the effect that the job satisfaction of care workers would have on the organization commitment. For this study, 230 care workers were surveyed via mail who were working at the long-term recuperation institutes for the elderly located in the eastern part of Jeollanam-do. 141 sets of questionnaires were used for analysis, excluding those with missing data. The collected data were processed by using the SPSS 18.0 to conduct the frequency analysis, reliability analysis, t/F-test, and hierarchical regression analysis. The results of analysis suggested the followings : First, the difference in organization commitment based on individual characteristics and job characteristics of care workers was found to exist, depending on the age related to individual characteristics and types of institutes and work types related to the job characteristics. Second, hierarchical regression analysis was conducted to analyze the effect that the job satisfaction of care workers would have on organization commitment. With the individual characteristics and occupation environment variables of care workers being controlled, it was found that the job satisfaction of care workers had the greatest effect on organization commitment. This implies that the extent of job satisfaction determines the commitment level of care workers for the concerned job.

The purpose of this study is to investigate factors affecting conflict of teachers in school. Researchers selected independent variables in personal, school, and local levels and analyzed their influence on conflict of faculty and staff, students and parents, and educational policy. We used 561 survey responses of teachers working in S City Office of Education and conducted hierarchical multiple regression analysis using SPSS 24.0. For results, we found out that variables such as career in the level of person, homeroom teacher and status in the level of school, and location in the level of region were statistically significant. Researchers suggested possible solutions which can be considered by school district and school officials.
