This study examined the effects of self-critical perfectionism on organizational citizenship behavior (OCB) and the moderating effects of gender in the relationship to understand deeply the dilemmatic situation resulting from OCB at the individual level. In other words, based on the conservation of resources theory, this study examined how self-critical perfectionism influences the OCB and how gender moderates the relationship between self-critical perfectionism and OCB. More specifically, this study predicts that self-perfectionism will be negatively related to OCB. Furthermore, this negative relationship between self-critical perfectionism and OCB will be strengthened in men compared to women. To test these hypotheses, the supervisor-subordinate survey was conducted, and 150 dyad data were analyzed. The analytical results of HLM (Hierarchical Linear Modeling) showed that self-critical perfectionism negatively influenced the OCB, and this negative effect was strengthened in men compared to women. This paper suggests implications and limitations for the literature on OCB.

In this study, we analyzed the longitudinal effect of participation in an overseas exchange student program on foreign language competence, intercultural competence, and personal development. Data were collected over three time points from the pre-, post-, and post-post tests with Korean college students who participated in an overseas exchange program. Hierarchical linear model was conducted to examine whether the change of participation effects exists over time and which predictors affected outcomes. The results of unconditional growth model showed that foreign language competence, cultural competence, and personal development showed statistically significant differences in their initial status prior to departure to participate in an overseas program as well as their growth rate. The results of conditional growth model showed that parents' level of education and overseas experiences before college affected the initial status of foreign language competence, and gender and overseas experience before college affected those of cultural competence as well as personal development. In case of growth rate, overseas experience before college and destination country/region affected foreign language competence, and interactions between Korean participating students and local students affected cultural competence. For personal development, only overseas experiences before college affected its growth rate. Lastly, relevant discussion and implications were provided.

Using KRIVET's Graduates Economic Activities Survey for 2005, this article examines the relationship between university ranking and labor market outcome, with a focus on wage differentials existing between provincial and Seoul metropolitan area university graduates. According to the analysis results, the average monthly wage for provincial university graduates was 1,747.7 thousand Korean won, which is 11.5% lower than that for graduates of universities in the Seoul metropolitan area. School effects on individual wage were estimated to about 12.2% after applying Hierarchical Linear Model technique, which means that university explains only an insignificant part of the total variance in wage among graduates. After controlling for the selection bias, the ability difference between the two areas, by applying the Heckman type 2SLS wage function and Neumark wage differential decomposition technique, the wage gap resulting from the segregation was not identified. This implies that, to a significant extent, the wage gap between provincial and Seoul metropolitan university graduates is attributed to the difference in productivity among individual graduates, rather than to the wage segregation. Also, the estimated wage function by applying Quantile Regression technique indicates that there does not exist any significant wage segregation difference by wage quantile.

This study aims to empirically examine the relationship between building energy consumption and building and local factors in Seoul. Building energy issue is an important topic for low carbon and eco-friendly city development. Building physical, socio-economic and environmental factors effect to increasing or decreasing energy consumption. However, there are different characteristic in each area, and this kind of variable has a hierarchical structure. The multi-level model was used to consider the hierarchical structure of the variables. In this study, a multi-level model was applied to confirm the difference between areas. Spatial area is Seoul, Korea and the temporal scope is August, summer season. As the result, in Model 1 (Null Model), ICC is 0.817. This shows that the energy consumption differs by 8.174% due to factors at the Dong level. Model 2 (Random Intercept Model) suggests that building's physical factors and Average age, Household size and Land price in Dong level have significant effects on Building energy consumption. In Model 3 (Random Coefficient Model), random effect variables have intercepts and slopes to vary across groups. This study provides a perspective for policy makers that the building energy reduction policies to be applied for buildings should be differently applied on area. Furthermore, not only physical factors but also socio-economic and environmental factors are important when making energy reduction policy.

본 연구는 스트레스가 지식창출에 미치는 영향을 보고자 한다. 즉, 개인의 목표에 대한 그리고 직무와 관련된 스트레스는 지식창출에 부정적 영향을 미친다는 연구들이 제시되고 있는데, 이때 팀의 어떠한 요소들이 이러한 부정적 영향을 감소시키고 지식창출에 기여할 수 있을지를 파악하고자 한다. 구체적으로 지식창출을 위해 자원에 비해 과도하게 설정된 목표로 인한 목표 스트레스(goal stress of resource inadequacy)와 지식창출을 위한 업무과정에서 발생하는 직무 스트레스(job stress)는 지식창출에 부정적 영향을 미칠 것이다. 그러나 지식창출을 위해 구성된 팀구성원들이 열심히 배우려고 하고 실패도 두려워하지 않는 분위기(팀 학습분위기) 속에서 강하게 결속되어 있다면(팀 응집력) 스트레스로 인한 지식창출에 대한 부정적 영향은 약화될 것으로 판단된다. 따라서 본 연구에서는 집단수준의 변수와 개인수준의 변수를 동시에 고려해야 하는 본 연구의 성격상 최근에 많이 사용되고 있는 다수준접근방법을 적용하여, HLM 6.08을 사용한 위계적 선형 모형분석을 수행하였다. 연구결과, 직무 스트레스는 지식창출에 부정적 영향을 미쳤으나 목표 스트레스는 유의한 영향을 미치지 않은 것으로 나타났다. 또한 팀의 학습분위기는 지식창출에 긍정적 영향을 미쳤으며, 목표 스트레스와 지식창출간의 관계에 조절효과를 하는 것으로 나타났다. 팀의 응집력 역시 지식창출에 긍정적 영향을 미치는 것으로 나타났다.

The purpose of this study is to investigate determinants of the saving behaviors, perceptions of economic situation and attitudes on the program of the Individual Development Account program participants in Korea. Data used for this article was the survey on the participants of 'Seoul Hope-plus Saving Account Program' implemented by Seoul Welfare Foundation for 3 years. In order to consider variances within-individual and between-individuals, Hierarchical Linear model is used for this study. The results are as follows. First, In demographic factors, disability, gender, education level, marriage status are significant factors on the effectiveness of the program. Second, the participation on the program has positive effects on the conception on the living standard and economic status of the participants. However, total amount of savings excluding savings on 'Hope plus' has decreased. The household income is positively related with the amount of savings. Thus, it is necessary to consider individuals' socio-demographic factors to planning the asset-based program.

The object of this article is to examine the effect of the quota-levy system on employment outcome of people with disabilities in Korea. Merging the data from disability employment report of 16,246 businesses in 2011 and the macroeconomic indicators such as regional economic condition, the author analyzes the effect of quota-levy system on employment outcome of persons with disabilities by using Hierarchical Linear Model(HLM). The finding is that imposing the levy on businesses affects employment outcome of people with disabilities but regional economic condition does not. The rate of employees with disabilities of the levied business is 0.7%p higher than that of the other business. The result of analysis implies that employment outcome of people with disabilities is influenced by the quota-levy system rather than regional economic condition.

This study aims to examine the intermediary roles of employee performance between high performance work system (HPWS) and its operational performance on the resource based view. Taking into account the unit of analysis, this study used a hierarchical linear modeling analysis in order to test rigorously the association between HPWS at the organisational level and employee performance at the individual level. For this empirical test, Human Capital Corporate Panel (HCCP) data including 316 firms and 7,872 respondents (including 923 team leaders) were used. To meet the unit of analysis and test the mediation effect, data at the individual and team level were aggregated into the organisational level. The empirical results show that HPWS have a positive impact on operational performance as well as employee performance such as job satisfaction, organisational commitment and organisational trust. Regarding the mediation effect, job satisfaction and organisational trust mediate between HPWS and operational performance. Theoretical implications are discussed in conclusion.

The purpose of this study explored the effects of supervisory relationship, conceptualized as working alliance, on social workers' working satisfaction and burnout. The consented participants were 68 supervisors and 80 supervisees working at Social Service Centers located in Seoul and Kyung-ki Province. Hierarchical linear model analyses of survey results from supervisors (n=68) and workers (n=80) revealed that the workers' sense of rapport within the supervisory relationship is related to working satisfaction. While it was expected that the supervisory relationship would also relate to levels of burnout, no association was found in the analyses. However, strong negative correlations were found between the supervisees' feelings of rapport within the supervisory relationship and both emotional exhaustion and depersonalization. The implication of future research and of social work practice and policy were added.

The purpose of this study is to compare and analyze the effects of the educational context variables on 8th-grade science achievement of 5 top performing countries(Korea, Singapore, Taiwan, Hong Kong and Japan) in TIMSS 2015. TIMSS 2015 science data and questionnaire results were used for fitting Hierarchical Linear Model (HLM) in this study. According to the results, such student-level variables as home resources for learning, students' interest in science learning, valuing science, Students' Educational Expectations gave significant influence on the science achievement of Korean students. School-level variables including Student Economic Background, and School Emphasis on Academic Success gave significant influence on the science achievement of Korean students. Comparing 5 countries, home resources for learning, students' interest in science learning, Students' Educational Expectations gave significant influence on the science achievement in all 5 countries. At the school level, Student Economic Background is statistically significant in explaining students' science achievement gap in all countries except Japan, and Teaching Limited by Student Needs gave significant influence on the science achievement in all countries except Korea. Discussed in the conclusion are ways to improve middle-school science teaching and learning including reducing the education divide among socioeconomic status, teaching innovation for competency education, inquiry and reinforcement of lab activities in science classes, and so on.
