The purpose of this study was to propose a proper method for the multilevel mediation analysis, for which the hierarchical method should be utilized, then MLM (multilevel modeling) approach as a hierarchical method has been popularly utilized until MSEM (multilevel structural equation modeling) approach was not proposed. This purpose was covered by three research questions about statistical methods, analytic procedure, and real example. First, MSEM statistical method was preferred to MLM method for its estimation accuracy and analytic flexibility. Second, the four-step procedures of model building, assumption examination, model comparison, and coefficient testing were proposed for the multilevel mediation analysis. Third, the real data of 2695 students of elementary and secondary schools and 89 teachers were analyzed in the multilevel directions of $2{\rightarrow}2{\rightarrow}1$ and $1{\rightarrow}1{\rightarrow}2$. Out of these directions of $2{\rightarrow}2{\rightarrow}1$, and $1{\rightarrow}1{\rightarrow}2$ model, only the coefficient of $2{\rightarrow}2{\rightarrow}1$ model was significant at the 95% CI. Mplus programs used for the real example are attached on the Appendix. Based on the results, significance and limitations of this study, were discussed in detail.

One of the main objectives of this paper is to identify the mediating effects of both social and intellectual capitals in the relations between entrepreneurship and innovation performance in Small and Medium Businesses. Based on the previous literatures on their relationships, we set our research model and test our hypotheses through a questionnaire survey. The main results of our analyses are as followings: first, entrepreneurship has a significant effect on innovation performance; second, social capital has a significant mediating effect between entrepreneurship and innovation performance; and finally, there exists a significant mediating effect between intellectual capital and entrepreneurship. One of the main policy implications of this study would be that the level of both social and intellectual capitals, coupled with entrepreneurship, should be reinforced in order to improve innovation performance.

The purpose of this study was to examine the effect of decentering and self-silencing in a relationship between socially prescribed perfectionism and social anxiety. We predicted self-silencing would function as a mediator in this relationship, and that decentering would moderate this mediation effect. To investigate this aim, three hundred seven university students were surveyed. All variables showed statistically significant correlations, and there was no statistically significant difference in the moderating effect of decentering in the relationship between socially prescribed perfectionism and social anxiety. Conversely, this study showed that there was a significant difference in the moderating effect of decentering in the relationship between self-silencing and social anxiety. In addition, socially prescribed perfectionism affected social anxiety through self-silencing, and decentering moderated the mediating effect of self-silencing. Implications and potential follow-up studies are discussed.

The mediation methods suggested by Baron and Kenny, Sobel, Aroian and Goodman, have widely used to test the mediating effect. However, as there are many problems in statistical test power, as well as statistical accuracy, a bootstrapping technique has been suggested as an alternative. In this paper, we adopt the phantom variables based on the bootstrapping technique to test the mediating effect in multiple mediator model consisting of three or more mediating variables. In particular, we formulate the multiple mediator model for analyzing the relations among organizational resources, the absorption capacity as mediating variables and technology commercialization capabilities. And using the bootstrapping approach, we analyzed the mediating effect of the absorption capacity by setting of phantom variables and calculated total indirect effect size and the statistical significance. The empirical results are as follows. First, we confirmed that the bootstrapping approach and the phantom variable is the very efficient and systematic mediation method. Second, we recognized that there is a difference in the mediating characteristics of the absorption capacity depending on the resource characteristics of human resources and material resources obviously.

This study is to analyze the relationship between Taeoom(workplace bullying) and organizational performance and to investigate the mediating effects of organizational silence between the relationship among nurses. In order to test the causal and mediating effects, this study employs the mediation analyses with regression. The sample is 273 from A university hospital in Seoul. Based on the results, Taeoom is basically, negatively associated with organizational performance. Acquiescence silence has played a full mediating role in the relationship between Taeoom and organizational performance. That is, Taeoom is not directly associated with organizational performance; however, it has a negative effect on organizational performance through acquiescence silence. Defensive silence plays a partial mediating role in the interdependence relationship. The implications of this study are that the negative effects of Taeoom would increase organizational silence and performance directly and indirectly; therefore, it is necessary to provide institutional prevention of Taeoom.

This study verified the effectiveness of authentic leadership in promoting coopetition with the mediation of positive psychological capital and identified how this mediating effect of positive psychological capital is moderated by performance-based rewards Our findings showed that positive psychological capital played the role of mediator (indirect effect) between authentic leadership and coopetition. Also, performance-based rewards had negative conditional direct effect on the relationship between authentic leadership and coopetition as well as a positive mediated moderation (conditional indirect effect) when the relationship is mediated by positive psychological capital. This research presents a novel empirical study on the mechanism involved in the promotion of coopetition among organization members, especially concerning the antecendents involved at the individual level.

The purpose of this convergence study was to evaluate the influence of interpersonal problems on sleep quality in college students and to analyze the mediating role of mental health and the moderated mediating role of emotional regulation. This was a cross-sectional study of 307 students at a college in Seoul. The results of hierarchical linear regression showed that interpersonal problems and mental health were statistically significant predictors of sleep quality in college students. A mediation analysis further revealed that students' mental health mediates the relationship between interpersonal problems and sleep quality. Additionally, there was a moderated mediating role of dysfunctional emotional regulation in this process. Our findings suggest that supportive and adaptive cognitive emotional regulation educational programs should be designed based on college students' maladaptive emotional regulation experiences and individual characteristics.

The mediacy is now evolving with the development of mankind civilization. In the evolution, mediacy shows duplicate logic of remediacy with the opposite mediacy property between immediacy and hypermediacy. The duplicate logic of remediacy is defined as a result of hypermediacy which clearly requires transparency and absorption of immediacy. Because of changes from analog to digital age and the development of image technique, At present, the era is coming when the splendid and spectacle visual speaks for the screen not well-organized script and direction. With this developing period, the research for visual effect is actively performed and advanced to the new study. Though the study of visual effects contains the hypermediacy trait, it is also conjugated as a research field for immediacy on the screen which is the wish of content production directors. In this study, the analysis of case study for the movie "The Lord of The ring"'s visual effect application is carried out. Also, it is investigated that visual effects can guarantee for the verification of valuable new research filed which insure transparency and absorption in the hypermediacy results. Furthermore, on this study, it is executed for the contribution of the identity and systematization in the new research field "Visual Effects".

The purpose of this study was to identify the impact of chewing ability on cognitive function of older people in Korea and the mediation effect of physical function and depression using the nationwide data from "Survey of the Living Conditions and Welfare Needs of Korean Older Persons in 2014", in Korea. This study was conducted on a total of 10,451 respondents in the "Survey of the Living Conditions and Welfare Needs of Korean Older Persons in 2014" and the data collection period was from June 11, to September 4, 2014. Chewing ability was used in the scale on level of daily life inconvenience in chewing ability (meat or hardness). Cognitive function was measured using MMSE-DS, physical function using K-IADL, and depression using SGDS-K. The data were analyzed using the SPSS 24.0 program and Process Macro. Total effects of chewing ability on cognitive function were not significant(p>.05). Direct effects of chewing ability on cognitive function were not significant(p>.05). There were the dual mediation effect(p<.05) of physical function and depression, a complete mediating effect by physical function(p<.05) or depression(p<.05) in the impact of chewing ability on cognitive function of older people in Korea. These results indicate that physical function and depression effect directly and indirectly in the impact of chewing ability on cognitive function of older people. In conclusion, it is suggested that to prevent the decline of cognitive function in older people, it is necessary to consider not only nursing strategies for strengthening chewing ability and physical function, but also nursing interventions for relieving or preventing depression in older people.
