  • It is almost impossible for firms to possess all of resources and capabilities needed to create technological innovations in modern competitive environment. This situation forces firms to conduct R&D collaboration. Therefore, this paper analyzes an effect of appropriability protecting knowledge exclusively on R&D collaboration and product innovation performance. In addition, we investigate how the governmental R&D support moderates and influences those relationships through empirical analysis. The results of moderated mediation show that the impact of appropriability on product innovation performance appears to be a common pattern in each conditional indirect effect of appropriability regardless of financial, direct, indirect R&D support of the government. The more governmental R&D supports increase over a certain level, the more conditional indirect effects of appropriability on product innovation performance increase through the vertical R&D collaboration. However, conditional indirect effects of appropriability through horizontal R&D collaboration are not significant in all levels of government R&D supports. If we utilize an analysis of moderated mediation by applying governmental R&D supports as a moderator, it is possible to analyze a significant strength of innovation policies and their performance. Therefore, this paper would make a contribution to an evolution of governmental R&D support and an effective formulation of innovation policy.

  • Objective : Previous research showed that childhood trauma or domestic violence resulted in difficulties in controlling emotion and problem solving and vulnerability to psychiatric disorders. To understand the long term effect of childhood trauma, this study investigated their influences on cognitive processing of anger-evoking event and anger behavior among prisoners. Methods : All data were collected from 198 prisoners off our districts in Korea. After they consented to participate, prison officer distributed a questionnaire that included scales to demographic measure, childhood abuse (emotional abuse, physical abuse, and neglect), cognitive response of anger (attentional focus, suspicion, rumination, and hostile attitude) and behavior of anger (impulsive reaction, verbal aggression, physical confrontation, and indirect expression). For statistical analyses, SPSS 18.0 were used and path coefficients were evaluated from the structural equational modeling using LISREL 8.52. Results : Almost 50% of prisoners of our sample experienced one or more trauma during childhood. Then we tested the long term effect of childhood trauma on anger response by structural equation modeling. As expected, childhood trauma was associated with cognitive processing of anger-evoking event and anger behavior. More specifically, emotional abuse (${\beta}$=0.21, p<0.01) predicted suspicion which in turn associated with impulsive reaction (${\beta}$=0.73, p<0.001) and verbal aggression (${\beta}$=0.87, p<0.001). Emotional abuse (${\beta}$=0.24, p<0.01) also predicted hostile attitude which associated with physical confrontation (${\beta}$=0.80, p<0.001) and indirect expression (${\beta}$=0.80, p<0.001). Interestingly, physical abuse associated directly with impulsive reaction (${\beta}$=0.23, p<0.01) and indirect expression (${\beta}$=0.17, p<0.05). Neglect predicted rumination (${\beta}$=0.15, p <0.05) which associated with indirect expression marginally (${\beta}$=0.11, P<0.10). Conclusion : The results of this study, suggest longitudinal and harmful effect of childhood trauma on difficulties in controlling anger. Especially, it was revealed that childhood abuse related with processing anger evoking events more suspicious and hostile and then various anger-expressing behaviors.

  • The purpose of this study is to establish the social support system for social integration by analyzing the effect of multicultural experiences on multicultural perception and stereotype and the meditating effect of multicultural perception. The research result is summarized as follow : First, multicultural perception is differently influenced according to multicultural experiences. That is, multicultural experiences have found to have the positive effect on multicultural acceptance and the negative effect on rejection about other cultures or prejudice about other cultures. Second, the result which analyzed the effect of multicultural perception on stereotype has found that acceptance about other cultures doesn't have any effect on stereotype. However, it can be found that the prejudice and rejection about other cultures are verified to be the variables which have the positive effect on stereotype. Third, the result which analyzed the direct effect of multicultural experiences on stereotype and the indirect effect through multicultural perception has found that multicultural experiences don't have any direct effect on stereotype, but do have the indirect effect through multicultural perception. With the help of information technology.

  • The purpose of this study is to investigate the effect of technology acceptance model (TAM) on behavioral intention in order to grasp the degree of technology acceptance on autonomous driving among the various factors that consumers perceive as unmanned vehicle system becomes commercialized. In addition to the mediating effect of perceived usefulness proposed by the existing TAM, this study proposed the perceived trust (PT) and hypothesized its mediating effect on behavioral intention to use the self-driving. Path anlaysis is adopted to investigate our hypothesis using the structural equation model. The sample used for the analysis was 149 valid data among 160 responses. The effects of total effect, direct effect, and indirect effect were confirmed by hypothesis test on mediating effect. Non-parametric bootstrapping analysis was also performed to confirm the robustness. All the hypotheses were significant and we found a partial indirect effect, which implies that mediation effect of PT on behavioral intention.

  • The purposes of this study were to analyze the effect of perceived parent-adolescent communication on SNS addiction tendency among high school students and to investigate the mediating effects of self-control on the relationship between above variables. 567 students who were registered in three high schools located in D city completed a questionnaire on parent-adolescent communication, SNS addiction tendency, and self-control. Structural equation models were conducted to compare the research model (complete mediating effect) and the competing model (partial mediating effect), and bootstrapping was conducted to investigate the mediating effects of self-control with SPSS 23.0 and AMOS 23.0. The results are as follow: First, while the parent-adolescent communication did not directly have an effect the SNS addiction tendency, the self-control had a direct effect on the SNS addiction tendency. Second, the research model was selected as a final model which implied that parent-adolescent communication had an indirect effect on SNS addiction tendency among high school students. Third, self-control had a significant mediating effect on the relationship between parent-adolescent communication and high school students' SNS addiction tendency. Based on the results of this study, it can be concluded that parent-adolescent communication had an indirect effect rather than a direct effect through self-control on high school students' SNS addiction tendency. This result indicates that the SNS addiction tendency rate of high school student can be lowered, by mediating self-control. Finally, this study suggests that the implicit points on counseling methods to remedy self-control of high school students, and shortcomings and limits of this study and advice for follow-up studies all be discussed.

  • Objectives The purpose of the present study was to examine the relationship between the chronotype and the burnout, so we investigated the mediating effects of the mediators such as perceived stress, stress response, and depression. Methods Employees working at Incheon Customs conducted a mental health self-examination through the internet. Among them, 174 people who agreed to the mental health survey participated in the study. Participants completed questionnaires including Composite Scale of Morningness (CSM), Center for Epidemiological Studies-Depression Scale (CES-D), Perceived Stress Scale (PSS), Stress Response Inventory (SRI), Maslach Burnout Inventory-General Survey (MBI-GS). Results Our results showed a higher degree of CES-D, SRI, exhaustion, and cynicism in evening and intermediate type compared to morning type, and a higher degree of professional efficacy in morning type compared to intermediate type. CSM was shown to have a direct effect on exhaustion and indirect effect through CES-D and SRI. CSM also had a direct effect on professional efficacy and had an indirect effect through the CES-D. However, CSM was found to have only indirect effects through the SRI for Cynicism. Conclusions In this study, individuals with evening type tend to experience a high degree of burnout (exhaustion, cynicism and professional efficacy) through the mediation effect of depression and stress response. Further study is necessary to reveal the effect of management of the depression and stress response in the employee with evening type.

  • This study explores the applicability of social capital theory in IT project management. Specifically, an empirical model is developed using different types of leadership competencies (emotional, cognitive, and social) as independent constructs impacting IT project performance. Social capital shared among team members are measured and placed as a mediating construct between leadership competencies and performance. Using PLS analysis of 120 data points collected through a survey of IT project participants in two large electronic manufacturers, direct and indirect impacts of leadership competencies are explicated. Research results reveal that emotional leadership competency seems to directly influence the project performance but not through team social capital, while social leadership competency seems to indirectly influence the project performance through team social capital but not directly onto the project performance. Cognitive leadership competency is the only leadership competency that maintains direct and indirect influence on project performance. Total effect of cognitive competency on project performance is almost two times larger than the total effect of emotional leadership competency and six times larger than the total effect of social leadership competency. Implications of findings are discussed at the end, and further studies are suggested.

  • This study provides an efficient marketing strategy for the cosmetic market by analyzing the effect of consumer desire on buying motive, brand satisfaction, brand attachment, and brand loyalty. The research conducted a survey using convenience sampling for adult women (from 20 years to 60 years) who purchased cosmetic items within 6 months. A total of 463 samples were used for the final analysis. Data analysis consisted of descriptive statistics, Cronbach's alpha, a confirmatory factor analysis, and a structural equation modeling analysis. Customer cosmetic consumption need had six factors: exhibition need, safety need, need to look younger and to pursue beauty, need to go along with others, eco-friendly need, and pleasure need. The buying motive had four factors: others-oriented motive, motive to keep skin healthy, economic motive, and motive to change products. The causality model showed that customer consumption need influenced buying motive, brand satisfaction, brand attachment, and brand loyalty. There were also significant effects on buying motive for brand satisfaction, brand attachment, and brand loyalty. In addition, there were indirect effects on the relationship between customer consumption need and brand loyalty. The pursuit for pleasure had a significant indirect effect on brand loyalty.
