In this paper, the effect of daily creativity of engineering students on problem-solving ability is addressed through the dual mediating effect of teamwork competency and self-directed learning ability. To this end, a regression-based statistical mediation analysis has been performed on the dual mediation model in which daily creativity and problem solving ability were treated as independent and dependent variables respectively, and teamwork competence and self-directed learning ability were included as mediation variables. The analysis result confirmed that the daily creativity has direct effect on the problem-solving ability, as well as indirect effects through teamwork competence and self-directed learning ability. In particular, the serial mediating effect of teamwork competency and self-directed learning ability was also confirmed to be statistically significant in the relationship between daily creativity and problem-solving ability. This verifies that problem-solving ability can be improved not only directly by improving daily creativity but also indirectly by improving teamwork competence and self-directed learning ability. In addition, teamwork competency showed greater indirect effect on problem-solving ability than self-directed learning ability, so increasing teamwork competency has a more significant effect on improving problem-solving ability than increasing self-directed learning ability. Therefore, in order to develop better problem-solving ability, it is necessary to identify and improve the learners' teamwork competency first and to strive to create an environment where learners can solve problems based on mutual trust with their teammates.

Objective: This study aimed to investigate the moderated-moderated mediating effects of children's media content selection and parental restrictive media mediation on the relationship between children's screen media time and executive function difficulties. Methods: A total of 693 parents of children aged 5~6 years participated in this study and were asked to answer all survey questions. The data were analyzed by descriptive statistics and correlation analysis using SPSS 27.0. Model 11 of PROCESS macro 4.3 was used to examine the moderated-moderated mediation model. Children's gender, age, childcare enrollment status, and household income were included in the analyses as covariates. Results: The moderated-moderated mediating effects of children's media content selection and parental restrictive media mediation were found to be significant. Specifically, bedtime mediated the relationship between screen media time and executive function difficulties only when parents did not appropriately implement restrictive mediation and children freely selected media content. Conclusion/Implications: It is recommended that parents understand the importance of implementing restrictive media mediation and selecting appropriate media contents for their child to prevent executive function difficulties in early childhood. Also, child education or day-care centers should offer education program about appropriate media use to reach more parents.

This study examined how the relationship between grandmother-adult child solidarity, caregiving satisfaction, and grandmother's child-rearing role varies according to the relation with the grandchild. Mediation effects and moderated mediation effects were analyzed to investigate the relationship between these variables. The participants were 295 grandmothers raising preschool-aged grandchildren in the Seoul and Gyeonggi areas. Data was analyzed using SPSS 23.0 and PROCESS macro, performing correlation analysis and hierarchical regression analysis. The statistical significance of the indirect effect was examined using a bootstrapping procedure. The results are as follows. First, grandmother-adult child solidarity directly affects the grandmother's child-rearing role. Second, grandmother-adult child solidarity indirectly affects the grandmother's child-rearing role through caregiving satisfaction. Third, the direct and indirect effects of grandmother-adult child solidarity on the grandmother's child-rearing role are moderated by the relation with the grandchild. The direct effect of grandmother-adult child solidarity on grandmother's child-rearing role was therefore shown to be significant on the maternal grandmother. Fourth, the indirect effect of grandmother-adult child solidarity on the grandmother's child-rearing role through caregiving satisfaction was shown to be significant on the paternal grandmother. Based on the results of this study, we discussed ways to strengthen the capacity of co-parenting between grandparents and adult children.

In this paper, we present an ontology mediation solution based on the methods frequently used in Formal Concept Analysis. Our approach of mediation is based on the existence of instances associated to two source ontologies, then we can generate concepts in a new ontology if and only if they share the same extent. Hence our approach creates a merged ontology which captures the knowledge of these two source ontologies. The main contributions of this work are (i) to enable the creation of concepts not originally in the source ontologies, (ii) to propose a solution to label these emerging concepts and finally (iii) to optimize the resulting ontology by eliminating redundant or non pertinent concepts. Another contribution of this work is to emphasize that several forms of mediated ontology can be defined based on the relaxation of certain criteria produced from our method. The solution that we propose for tackling these issues is an automatic solution, meaning that it does not require the intervention of the end-user, excepting for the definition of the common set of ontology instances.

Purpose: The aim of this study was to examine the relationship between handwashing knowledge and handwashing compliance in nursing students and to identify the moderation and mediation effects of self-efficacy and perceived behavioral control on the relationship. Methods: The participants were 172 nursing college students who completed the self-report measures. Data were analyzed using t-test, ANOVA, and Pearson correlation coefficient, Multiple regression analysis was used to test moderation and mediation effects. Results: The score for knowledge of handwashing was higher in participants who had completed fundamentals of nursing practicum (t=-6.54, p<.001) and the score for compliance with handwashing was higher in participants who had completed clinical practicum (t=-3.81, p<.001) or fundamentals of nursing practicum (t=-5.97, p<.001). Self-efficacy showed a significant moderation effect (z=2.21, p=.027) but not a mediation effect while perceived behavioral control had a significant mediation effect but not a moderation effect on the relationship between knowledge of handwashing and compliance. Conclusion: Findings indicate that clinical practicum and fundamentals of nursing practicum were helpful to nursing students in acquiring knowledge and in practicing proper handwashing technique. These findings suggest that continuing and repetitive education programs on handwashing need to be enhanced and strategies to strengthen self-efficacy and perceived behavioral control need to be included in education programs.

Objective: The purpose of this study was to identify the mediation effect of value of children in the relationship between maternal parenting stress and ideal number of children and to verify whether perception of the adequacy of national public childcare facilities moderates this mediation relationship. Methods: For the analysis, the 6th year results (2013) from the Panel Study on Korean Children by the Korean Institute of Child Care and Education were used. The main subjects of the study were 1,611 mothers with children aged 60 - 66 months. Results: First, there was a partial mediation effect of mother's parenting stress influencing the ideal number of children through the value of children. Second, the enhancing effect of the perception of the adequacy of national public childcare facilities moderating the value of children and ideal number of children was verified. Third, perception of the adequacy of national public childcare facilities had enforcing effects moderating the value of children and ideal number of children and mediation effects moderating the influence of maternal parenting stress on ideal number of children through the value of children. Conclusion: Based on the results, it was confirmed that the expansion of national public childcare facilities is a factor strengthening the maternal intention of birth.

Objectives: This paper examines the mediation effect of depression in the relationship between parental abuse, parental alcoholism, and suicidal ideation in university students. Methods: A survey on abusive experience from parents, parental alcoholism, depression, and suicidal ideation was conducted with 415 students from six universities. Structural equation analysis was performed using the AMOS program. Results: The result demonstrates that depression has some mediation effects between parental abuse and suicidal ideation in university students. Meanwhile, depression has an entire mediation effect between parental alcoholism and suicidal ideation. Conclusions: This study shows that the parental alcoholism by itself did not affect suicidal ideation in university students, but depression did. Experience of parental abuse is a significant risk factor which may cause suicidal ideation, and depression may cause suicidal ideation indirectly. It calls for efforts to prevent parental abuse and emphasizes the necessity of paying primary attention to the mediation effect of depression in preventing suicidal ideation.
