The purposes of this study were to examine the two processes of social comparison and self-comparison, and to suggest the applications of social comparison theories and self-comparison theories. For these purposes, social comparison theory, self-evaluation maintenance model, control theory, self-discrepancy theory, regulatory focus theory, and temporal comparison theory were reviewed. The processes of social comparison and self-comparison are different, but both comparisons are similar in that they have some effects on self-evaluation, emotion, motivation and behaviors. Suggestions on education, health, economic justice and interpersonal relationships were discussed.

오늘날의 화훼산업에 있어 생산물의 품질을 결정짓는 요인은 여러 측면에서 생각해 볼 수 있겠지만, 생산자적 측면에서는 화색, 화형, 일률적인 초장 등이 무엇보다 중요하다고 판단된다 최근 화훼산업이 단일종으로 대형화, 전문화되어 감에 따라 하우스 내에서 생장을 조절하여 상품을 획일화 균일화시키고, 출하날짜 등을 맞추기 위한 여러 종류의 기술들이 필요해지고 있다.(중략)

The purpose of this study is to investigate the effect of leader-member exchange (LMX) on envy and counterproductive behaviors (CWB) moderated by similarity. Specifically, we focused on the negative side of LMX to examine the relationship between LMX and envy, and the mediating role of envy on the relationship between LMX and CWB. Further, we also examined the moderating role of similarity on the relationship between envy and CWB. Given that CWB can be harmful to any organizational, it was worthwhile to find possible antecedents of CWB, envy and LMX. A total number of 238 employees participated in this study and the results supported our hypotheses. The results of this study can have managerial implications, showing the important role of manager's personalized treatment for each of his/her subordinates.

The importance of organizational learning is increasing. Drawing on regulatory focus theory and upper echelon theory, this study aims to identify the relationship of the regulatory focus of managers and three aspects of organizational learning, namely breadth, depth, and speed of organizational learning. While identifying the significant influence of promotion focus on the three aspects of organizational learning, we found that the influence of promotion focus of breadth of organizational learning is statistically stronger than that of prevention focus.

Information security has been a major concern in organizations. The longstanding question of how to improve employees security behaviors and reduce human errors remains unanswered and requires further exploration in the information security domain. To do this, we propose a risk compensation theory-based model and examine the model. Research results shows that the relationships between information security countermeasures and information security compliance intention of employees are moderated by system vulnerability. However, the finding is contrary to the previously held risk compensation assumption and deserve further study. In addition, system quality does not play a moderator role in the relationship. Conclusions and implications are discussed.

Quantitative evaluation indexes for flood control effect of a multi-purpose reservoir used widely in Korea are the discharge control rate, reservoir release rate, reservoir storage rate, and flood control storage utilization rate. Because these indexes usually use and compare inflow, release, and storage data directly, the uncertainties included in these data are not considered in evaluation process, and the downstream flood control effects are not assessed properly. Also, since the acceptable partial failure in a design of water resources system is not considered, the development of a new flood control effect evaluation index is required. Fuzzy set theory is therefore applied to the development of the index in order to consider the data uncertainty, the downstream flood control effect, and the acceptable partial failure. In this study, the flood control effect of a multi-purpose reservoir is evaluated using the flood control effect index developed by applying fuzzy set theory. The Chungju reservoir basin was selected as a study basin and the storm events of July, 2006 are used to study the applicability of the developed index. The related factors for flood control effect are fuzzified, the acceptable failure region is divided from the system state to evaluate the flood control effect using developed flood control effect index. The flood control effect index were calculated by applying to the study basin and storm events. The results show that the developed index can represent the flood control effect of a reservoir more realistically and objectively than the existing index.

In this article, a fairly extensive literature review was conducted to depict the current status of academic motivation and its developmental trend among Korean adolescents. The focal factors were perceived competence and autonomy which have been considered as major determinants of academic motivation. Theoretical frameworks adopted were self-efficacy theory, expectancy-value theory, and self-determination theory. Empirical studies conducted in Korean educational settings during the past decade were the target of the literature review. Results of the literature analysis revealed that, in general, there was a decreasing tendency in perceived competence from elementary to middle school which followed by a slight increase after entering high school. Similar trend revealed in the development of autonomous motivation, in that middle and high school students' intrinsic motivation levels were lower than that of the elementary groups. The amotivational tendency was increased as the grade level proceeded toward high school, which requires attention from educators. Discussion was followed in an attempt to provide plausible interpretations for this undesirable current status of Korean adolescents' academic motivation and to suggest implications for possible remedial actions both in pedagogical perspectives and students' well-being.

Based on the affective event theory, the purpose of the study is to examine the effect of the individual difference regulatory focus on the process in which the work events affect job engagement under organizational circumstances. To this end, 232 financial workers were surveyed on positive events, positive affects, regulatory focus and job engagement. The results of the analysis are as follows. First, the positive events generated positive affects and showed positive influence on job engagement. Second, the effect of positive affects on job engagement has been shown to be discriminatory depending on the level of regulatory focus. The higher the level of promotion focus, the stronger the effect on job engagement of positive affects, and the higher the level of prevention focus, the weaker the effect on job engagement of positive affects. Third, the moderated mediated effect was found to be significant only in the prevention focus. The magnitude of indirect effects on job engagement by positive events was found to be weakened when the prevention focus was high. Finally, the implications and future research issues were discussed.

The purpose of this study is to analyze the moderating effect of health privacy information on the relationship between the factors that affect the behavioral intention of the usage of u-health system have. Therefore, as a research hypothesis in TRA (Theory of Reasoned Action), self-efficacy and perceived usefulness will have a positive effect on the behavioral intention of the u-health system, and in the path, that personal information factors have an effect on each path. This study used the PLS-SEM methodology to verify the proposed research model. As a result of the analysis, this study showed that the moderating effect of health personal information in the presented model affects to some extent by the increase of R2 explanatory power. However, it was found that it was more consistent with the role of the independent variable rather than the moderating influence on the perceived usefulness.
