  • The purpose of this study is to examine the causal relationship of related variables in order to promote entrepreneurship, which is one way to support the economic independence and stable settlement of North Korean defectors. This study is firstly to examine the influence of individualism and collectivism on entrepreneurial intentions, and secondly, to examine the mediating effect of social adaptability in the relationship between socialist value system and entrepreneurial intention. To this end, a survey was conducted on North Korean defectors, and the empirical analysis target was 223 North Korean defectors. For the verification of the causal relationship between personal disposition and entrepreneurial intention, and the causal relationship between value system and entrepreneurial intention PLS was used. And PROCESS for SPSS Macro was used to verify the mediating effect of social adaptation in the relationship between the value system and entrepreneurial intention. Looking at the results of the empirical analysis, the extraversion factor was found to have a positive effect on the entrepreneurial intention level of North Korean defectors, and the self-fulfillment desire factor was found to have a positive effect on the entrepreneurial intention. It was also found that individualist values have a positive effect on the entrepreneurial intentions of North Korean defectors, and collectivist values do not have a significant effect on the entrepreneurial intentions. As a result of examining the mediating effect of social adaptability between individualism/collectivism and entrepreneurial intention in this study, it was found that individualist value has a direct impact on entrepreneurial intention without engaging social adaptability.

  • The purpose of this study is to empirically identify the process of technology acceptance of the metaverse, a virtual world-based platform that has attracted attention due to the 4th industrial revolution and the COVID-19 pandemic. The technology acceptance model (TAM) was used to identify factors affecting the use of the metaverse platforms and to analyze the causal relationship among these factors. For research, a survey was conducted on ordinary adult men and women and was analyzed using a structural equation model. The study found that perceived pleasure, interactivity, self-efficacy, and social influence had a positive effect on perceived ease-of-use. Interactivity and social influence had a statistically significant effect on perceived usefulness. The relationship between perceived ease-of-use and perceived usefulness was not statistically significant, but both perceived ease-of-use and perceived usefulness had a significant effect on positively forming attitudes toward metaverse. Lastly, favorable attitudes toward the metaverse platform had a positive effect on the intention to continue using it. Through this study, it was possible to identify the factors affecting the intention to use the metaverse and to confirm the causal relationship between the factors. A deeper understanding of users may be obtained in future if the research subject can be expanded and investigated with various factors.

  • Objective: Research on children's death concepts requires an approach considering social and cultural context. A qualitative method is necessary to explore children's cognitive process of understanding death. Thus, this study, to overcome the limitations of the quantitative approach based on the deductive logic led by adult researchers, adopted a qualitative research method. Methods: The data collection, referring to the theories of Corr and Balk (2010) and Smilansky (1987), used Death Concept Questionnaire. Each structured question was followed by open follow-up questions to explore how children understood each concept of death. Results: The results showed that participant children were still lacking in the acquisition of death sub-concepts. The qualitative result from open interview showed how children can and can not acquire the concepts of death. Conclusion/Implications: The study could be used in future development of death education programs for children. Based on the results of this research, it is necessary to develop programs for children's death education, which would help them coping with death related anxiety and loss experiences.

  • E-authentication is one of the key functions for electronic transactions with the identification function made through the information systems. With the abolition of the mandatory use of public certificates, various private e-authentication services have emerged, and are developing to provide various additional services in addition to e-authentication. In this study, we explored the factors that affect user satisfaction with e-authentication services, compared the relative influence among the factors that we explored, and produced implications that could contribute to strengthening the competitiveness of e-authentication services. Based on the characteristics of e-authentication service, we searched and found four factors such as availability, convenience, added functionality and security. After that, we established and analyzed our research model to analyze the causal relationship between these four factors and user satisfaction. The analysis results showed that availability, convenience and security had significant effects on user satisfaction, but added functionality had no significant impact. In addition, compared to availability and convenience, security had a very strong impact on user satisfaction. This study suggests that e-authentication service providers should make efforts to make users aware of the usefulness of additional services while enhancing security.

  • We test the hypothesis that the gradual diffusion of information across asset markets leads to cross-asset return predictability in Korea. And, the aim of this paper is related to forecast the stock market, business cycle index and industrial production by various indicators of economic activities in Korea. For this, our paper sets models and focuses on empirical test. The stock market on this month correlate with industries in Korea. The stock market doesn't lead to industries. The industries and macroeconomic variables have high correlation. We test that gradual diffusion of industrial information will predict stock market in Korea. For this, we analysis on possibility of Granger cause by VAR models between industries and stock market. As a result, 21 portfolios cause to Kospi statistically significance at 5%. Especially, the Beverage portfolio has bilateral Granger causality to Kospi. In case of Internet and Cosmetics portfolio, Kospi has unilateral Granger causality to it. The predictability of specific industries has a relation to Macroeconomic variables. What industrial portfolios predict to Business Coincidence Index? The only 6 industrial portfolios of 36 portfolios have a statistically significance at 10%. And, 9 portfolios have a statistically significance at 5%.
