Purpose: The purpose of this study was to draw practical implications applicable to the field by analyzing a double-mediator model of social participation and depression in relation to the utilization of Information Communication Technology (ICT) and cognitive function. Methods: The data from the Fifth Living Profiles of Older People Survey in Korea was used, and the sample included 3,925 people, 75 years of age or older. Descriptive statistics, correlation analysis, and the PROCESS macro test were used for verification of the double mediator model. Results: The results were as follows: First, ICT utilization was rated at an average of 1.4 out of 10, social participation at an average of 1.1 out of 7, depression at an average of 3.72 out of 15, and cognitive function at an average of 22.42 out of 30. Second, ICT utilization has a significant effect on cognitive function. Third, the mediating effects of social participation between ICT utilization and cognitive function were significant. Fourth, the mediating effects of depression between ICT utilization and cognitive function were not significant. Fifth, the serial double mediator effects leading to ICT utilization, social participation, depression, and cognitive function were significant. Conclusion: The study discussed the implications of maintaining and protecting cognitive function in the vulnerable elderly through the utilization of ICT.

The purposes of this study are to examine the differences of gender role identity according to general characteristics, parenting behavior, and family function, and to find out the main predictors of gender role identity, in order to further test the mediating effects of family function between parenting behavior and gender role identity among middle school students. Six hundred-fifty 3rd graders from three middle schools in Busan participated in this study. The results showed that the significant variables for predicting the masculinity of gender role identity include family cohesion, and parenting behaviors (father's reasoning, mother's over-expectation) and monthly household income, respectively. The significant variables for predicting femininity were family cohesion, and father's intrusive parenting behaviors, father's educational background and the mother's affection, respectively. The results indicated that for masculinity, family cohesion played the full mediator with the father's monitoring behavior and the partial mediator with the father's reasoning behavior. Similarly, for the mother's reasoning and affection, family cohesion played a full mediator. For femininity, the family cohesion played the full mediator with the father's affection and the partial mediator with the mother's affection. Similarly, for androgyny, the family cohesion played a role of full mediator with the father's monitoring, reasoning, affection and mother's reasoning and affection. In other words, the parents'positive parenting behaviors affected the family cohesion, and in turn, had an impact on the formation of the gender role identity.

This study was conducted in order to find out protective factors on adolescent's social withdrawal. The purpose of this study was to test the mediator effects of adolescent's ego-resilience in the relation between affectionate parenting attitudes and adolescent's social withdrawal. The data were collected from 586 students of high schools located in 'D' city, Korea. Adolescents completed questionnaires on 'My Memories of Upbringing(EMBU-short)', ego-resilience, and 'Korean Youth Self Report(K-YSR)' scales. The correlation and structural equation model were conducted to examine the relations between the variables by using the SPSS 21.0 and AMOS 21.0. The results are as follow: First, while the affectionate parenting attitudes did not directly affect the adolescent's social withdrawal, the ego-resilience had a direct effect on the adolescent's social withdrawal. Second, there was a significant mediator effect of the adolescent's ego-resilience between the affectionate parenting attitude and adolescent's social withdrawal. In conclusion, these results can be used as basic data to prevent social withdrawal of adolescents and increase their ego-resilience.

Xylanase (X) derived from Aurreobasidium pullulans and laccase-mediator system (LM) using Trichophyton sp. LKY-7 laccase (TrL) and N-hydroxy-2-pyridone analogue (NHP) as a mediator were applied in hardwood kraft pulp (HwKP) bleaching. The individual and the synergistic effects of X and LM stage were investigated in the enzymatic bleaching of HwKP. Also, the effects of subsequent alkaline extraction (E) and alkaline/hydrogen peroxide treatment (P) were examined. In X or LM treatment alone, an appreciable bleaching effect of HwKP was not observed, whereas subsequent E or P stage enhanced the increase of brightness and the decrease of kappa number. Especially, P stage significantly enhanced the bleaching effect of pulp. Bleaching of HwKP with XLM sequentially gave significantly higher pulp brightness and lower kappa number than that obtained after the treatment of HwKP with X+LM simultaneously. When HwKP was sequentially treated with XLM followed by P stage, the brightness increased by about 11% ISO and the kappa number decreased by about 3.6 in comparison with the initial pulp. Xylanase and laccase were strongly inactivated by NHP both in the absence and the presence of pulp.

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.

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 study addressed ways in which parental poverty factors are associated with child school performance and how these relationships may be mediated by self-regulated study performance. Data of the Korea Education Longitudinal Survey (KELS : 2005) were used in this survey of 6,908 students in 150 schools. Parental poverty status, self-regulated study performance, and school performance achievement were administered when children were in 7th grade. Using structure equation modeling analysis, the results of this study confirmed that self-regulated study performance is a mediator of the linkage between poverty and school performance. Thus, children's positive self-regulated study performance acts to buffer the negative cycle of poverty.
