This study examined the relationships between children's perceptions of mother's psychological control, and children's behavior problems(depression, anxiety, withdrawal, and aggression). In order to expand the study on the relationships, special attention was given to the possible mediator effects of children's emotional autonomy on the relationships. The subjects were 293 6th graders residing in Cheonan. It was found that children's perceptions of mother's psychological control was significantly related with the level of children's depression, anxiety, withdrawal, and aggression. Children's emotional autonomy were found to be a significant mediator of the relationship between mother's psychological control and children's depression and aggression. No significant mediator effect of emotional autonomy was found in the relationship between mother's psychological control and children's withdrawal and anxiety.

The purpose of this study is to analyse the effect of information application of the elderly on their lives through analysing the key papers on the topic. To achieve the aim of this study, we searched the papers from RISS, KISS, DBpia and the National Assembly Library of the Republic of Korea, using keywords such as 'the elderly and informationization,' 'the elderly and information application,' and 'mediator effect.' In the search process, we did not limited the publication year or journal types. A total of 476 papers were searched as the result of the initial search. Based on three researchers consent of selection criteria, we finally selected 19 papers and analysed the important mediator variables between the information application and the life satisfaction or happiness. Using the content analysis, we analysed the quantitative analyses (including sample characteristics and sociodemographic statistics) and qualitative analyses (including result interpretation and policy implication about the elderly information education). After in-depth analysis of the papers, we built a table organized by the independent variable and the mediator variable. With the results, several implications were discussed and contributions are also explained.

This study aimed to investigate the influence of spiritual leadership on innovative work behavior and the effect of knowledge sharing on job crafting. Furthermore, the roles of knowledge sharing as a mediator for the impact of spiritual leadership on innovative work behavior, and job crafting as a mediator for the relationship between variables, were also examined. This research employed quantitative analysis, including the PLS-SEM approach; SMART-PLS, a measurement and structural equation model was employed to explain the relationship between variables, and the effect of mediation. The population study consisted of all lecturers at the Faculty of Economics and Faculty of Economics and Business at the PTKIN in East Java, Indonesia, comprising 220 randomly-selected samples. The result showed spiritual leadership does not directly influence innovative work behavior, while knowledge sharing directly affects job crafting. The findings indicated knowledge sharing mediates the impact of spiritual leadership on innovative work behavior, and the role of job crafting as a mediator for the relationship between variables was accepted. Therefore, this research confirms a positive influence of knowledge sharing on job crafting, and indicates both factors play an important role in mediating between variables, and are important for lecturers' innovative work behavior.

The anti-inflammatory effect of Spirulina fusiformis on monosodium urate crystal-induced inflammation in mice has been investigated and compared with the non-steroidal anti-inflammatory drug Indomethacin. The paw volume, lysosomal enzyme activities, lipid peroxidation, anti-oxidant status and inflammatory mediator tumour necrosis factor-$\alpha$ were studied in control and monosodium urate crystal-induced mice after oral administration of Spirulina platensis in an experimental model for gouty arthritis. In the induced mice, the levels of lysosomal enzymes, inflammatory mediator tumour necrosis factor-$\alpha$, lipid peroxidation and the paw volume increased significantly, whereas the antioxidant status decreased when compared to control mice. $\beta$-glucuronidase and lactate dehydrogenase level were also found to be increased in untreated monosodium urate crystal-incubated polymorphonuclear leucocytes. After the oral administration of Spirulina fusiformis, the physical and biochemical changes observed in monosodium urate crystal-induced animals were significantly restored to near normal levels. The results clearly indicated the anti-inflammatory role of Spirulina fusiformis, a promising drug for gouty arthritis.

This research analyzed the characteristics of social capital and sharing economy, which are the new paradigm in the development of the entire society. In addition, it identified the social roles of a public library as a mediator that promotes the social benefit by conducting a survey questionnaire. As the results of the analysis through correlation analysis and hierarchical multiple regression analysis, social capital and sharing economy are the co-related societal phenomenon, and public libraries positively effect on the construction of social capital and the participation in sharing economy. From the perspective of the roles of a public library as a mediator between social capital and sharing economy, it was identified that various programs provided by public libraries positively effect on mediating social capital and sharing economy.

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.

In the two-condition within-subject mediation design, pairs of variables such as mediator and outcome are observed under two treatment conditions. The main objective of the design is to investigate the indirect effects of the condition difference (sum) on the outcome difference (sum) through the mediator difference (sum) for comparison of two treatment conditions. The natural condition variables mean the original variables, while the rotated condition variables mean the difference and the sum of two natural variables. The outcome difference (sum) is expressed as a linear model regressed on two natural (rotated) mediators as a parallel two-mediator design in two condition approaches: the natural condition approach uses regressors as the natural condition variables, while the rotated condition approach uses regressors as the rotated condition variables. In each condition approach, the total indirect effect on the outcome difference (sum) can be expressed as the sum of two individual indirect effects: within- and cross-condition indirect effects. The total indirect effects on the outcome difference (sum) for both condition approaches are the same. The invariance of the total indirect effect makes it possible to analyze the nature of two pairs of individual indirect effects induced from the natural conditions and the rotated conditions. The two-condition within-subject design is extended to the addition of a between-subject moderator. Probing of the conditional indirect effects given the moderator values is implemented by plotting the bootstrap confidence intervals of indirect effects against the moderator values. The expected indirect effect with respect to the moderator is derived to provide the overall effect of moderator on the indirect effect. The model coefficients are estimated by the structural equation modeling approach and their statistical significance is tested using the bias-corrected bootstrap confidence intervals. All procedures are evaluated using function lavaan() of package {lavaan} in R.

This paper examine the roles of social rapport and friendship which are the representative variables of strong emotional bonds between customers and firms in service relationship marketing. As results, social rapport and friendship were confirmed as positive moderators between a relational antecedent variable and a relational mediator variable. In other words, emotional bonds, such as social rapport and friendship, stimulated relationship development in service relationship marketing. Meanwhile, customer-firm emotional bonds seemed to be a negative effect on the stage of a relational mediator variable and a relational outcome variable. This meant that relational mediator variable and emotional bond variables(social rapport and friendship) individually had an positive effect on a relational outcome variable. If emotional bonds between customers and firms had already built, they could have positive influence on the relational outcome, regardless of relational mediator variables. Conclusively, firms' relational efforts focus on the building the emotional bonds with customers, not on the process of relational antecedents, mediators, and consequences.

The purpose of this study is to investigate the relationship among stress, smartphone addiction, and depression of university students and whether depression is mediators in the relationship between stress and smartphone addiction. For this purpose, data were collected from May 1st to 31, 2017 from 400 university students, and analyzed 381 valid ones. Frequency analysis, reliability analysis, correlation analysis and regression analysis were used as analysis methods; and the Soble test was conducted in addition to verification of mediator effect according to procedures of Baron & Kenny(1986) for verification of mediator effect. The results of this study are as follows. First, stress of the subjects was positively correlated with depression(employment stress r=.353, economic stress r=.193, heterosexual relationship stress r=.138) and smartphone addiction(employment stress r=.262, economic stress r=.178, heterosexual relationship stress r=.190). Second, depression was a statistically significant partial mediator between employment-stress and smartphone addiction(Z=2.7151, p<.001). Based on the results of this study, I proposed education/counseling programs that can relieve employment-stress and depression.
