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 aimed to clarify the continuance intention of users of size recommendation services. The expectation-confirmation model framed the analysis of the 180 data points collected. The analysis determined the mediating effects of perceived usefulness and satisfaction on the relationship between expectation-confirmation and continuance intention. The moderated mediation effect of familiarity was also analyzed, and a path analysis was conducted using PROCESS macro. Results showed that expectation-confirmation had a significant effect on perceived usefulness, satisfaction, and continuance intention. Findings indicated that perceived usefulness affected satisfaction and continuance intention and confirmed that satisfaction affected continuance intention. In the relationship between expectation-confirmation and continuance intention, mediation analysis verified the mediation and double mediation of perceived usefulness and satisfaction. In the group with an above-average familiarity value, moderation analysis confirmed a moderating effect between perceived usefulness and satisfaction. Above-average familiarity values also confirmed that the moderating effect on continuance intention was significant.

The purpose of this study was to examine the relationship between family strength and career decision-making difficulties and the mediating effect or career self-regulation. The results of the present study suggested the significance of family strength and career self-regulation in understanding career decision-making difficulties. With 172 Korean college students, there were both significant direct and indirect effects from family strength to career decision-making difficulties. Specifically, the mediation roles of career self-regulation was confirmed. Comparing the partial mediation model with full mediation model, the partial mediation model fits better with the data. These results have significant clinical implication that counseling practitioners need to address the possible influence of family strength on college student's perceived difficulties in career decision-making process and to assist students develop appropriate level of competencies of regulating one's emotion, thoughts, and behavior related to career problems.

Purpose - This paper is an empirical investigation of the mediation effect of innovation activity in industry transformation considering the relationship between the semiconductor industry and high-quality economic development. The research questions are whether the semiconductor industry drives high-quality economic development and if so, what is the semiconductor industry's role in high-quality development? We found that the semiconductor industry has clearly improved the quality of economic development, and its comparative advantage has significantly increased per capita national incomes. Furthermore, innovation activity proved to be an intermediary factor for the semiconductor industry to promote high-quality economic development. The world economy should aim to reasonably develop the international semiconductor industry and cultivate innovation markets. Design/methodology - Our empirical model considers the relationship between the semiconductor industry, innovation activity, and high-quality economic development. We constructed an analysis framework based on data from 199 World Bank economies between 1995 and 2019, and we used a mediation effect method to calculate the total effect of the semiconductor industry on promoting high-quality economic development, the indirect effect of the semiconductor industry on promoting innovation activity, and the mediation effect of these innovation activities on the promotion of high-quality economic development. Findings - The results show that the semiconductor industry has significantly promoted high-quality economic development. This is true even after the robustness test of grouping and alternative variables was applied. An analysis of the mechanism shows that promoting patents, scientific research, efficient government, and urban management innovation are important mechanisms for the semiconductor industry to release high-quality development dividends. Originality/value - Although it has been shown that specific industries like semiconductors can affect high-quality economic development through industrial upgrading, few researchers have attempted to empirically test the impact of the semiconductor industry on high-quality economic development. In this paper, we use a mediation effect model, alternative variables and a grouping test to find the internal mechanisms of the comparative advantage of the semiconductor industry in high-quality economic development from the perspective of innovation activity.

The purpose if this study was to find and investigate effective mediation factors influencing performance of servitization through servitization acceptance activities by means of empirical results. According to the previous researches, two main mediation factors which were related with servitization competencies such as ICT competency of servitization and competency of servitization process were distinguished from lots of competencies which are relying on servitization process. Using a 373 sample data investigated from CEOs, directors and managers of small and medium sized firms in Korea, the structured mediation model was proposed. The measurement for the each variable was accepted for this study when the respondents were revealed to understand the servitization concepts which explained especially company's business moving towards the service specific gravity from selling existing products. The measurement for the each variable reflected that respondents were participating in any sort of servitization type or had intension to be involved with any servitization categories. The mediation hypotheses were tested in the way of analytical measures with the result of strong reliability. According to analysis, two mediators showed positive mediation role and statistically adopted between servitization acceptance activities and servitization performance in the 99% significant level. We confirmed that ICT competency of servitization and competency of servitization process were in the role of positive mediation between servitization acceptance activities and performance of servitization. The total of indirect effects were 0.2546 to support each mediation hypotheses. Tested two mediators were not on the same level. The most affecting mediation element on servitization performance was appeared as competency of servitization process. With the result of this study, we expect that the small and medium sized companies might have servitization business strategies including proper service competencies and mediators through acceptance activities to obtain suitable performance. According to the analysis, Companies which consider product-servitization need to set strategies to reinforce above two competencies.

This study sought to examine the effect of three (distributive, procedural, and interactional) justice perceptions in predicting employees' motivation to participate in training activities. On the basis of theoretical linkages between the constructs, full mediation and partial mediation models by perceived benefits of training were developed. The models were tested using SEM (Structural Equation Modeling) on responses from 302 employees of three wireless operators in the Republic of Korea. The results showed the partial-mediation model is a dominant model. It also confirmed that interactional justice directly influence motivation to participate in training, whereas procedural justice influence the variable through perceived benefits of training. Furthermore, limitations and implications of the current study and directions for future work are discussed.
