Adolescents reach the game-use states of adaptive and maladaptive by the absorption to computer game. Authors claimed that the two states are commonly related with the time of game-use, and the degree of them are distinctive according to adolescent individuals, specifically their self-control propensity. Authors proposed a conceptual research model that Big Five personality types predict their self-control which moderates the relationships from game use-time to the maladaptive and adaptive states. The data to test its validity and reliability had been sampled 999 Korean students in elementary school, middle school, and high school. Resultingly, the openness and conscientiousness of the adolescents affected positively on the self-control, which moderated negatively the relationship from the game use time to the maladaptive use state, but the positive moderation on the relationships from game use time to adpative state was not significant. These results mean that we could apply teenager's Big Five personality type and their self-control traits as a tool for preventing teens from the overuse state like addiction.

Because the service is characterized by simultaneous production and consumption, the customer must participate directly in the delivery and production process of the service. For this reason, the variable Customer Participation has aggregated many empirical results in the service marketing field. Recent research on customer participation has focused on the relationship marketing, and is empirically identifying the relevance of customer participation and relative value of relationship marketing. These findings indicate that customer participation should be understood in a relationship between customers and service firms. Using commitment velocity and customer participation velocity considering dynamic of the relationship, this study aims to re-examine the relationship between customer participation and encounter satisfaction which is the foundation of relationship formation. Multiple regression analysis and hierarchical regression analysis are used as research methods. The study found that customer participation has a direct positive effect on encounter satisfaction, and that commitment velocity and customer participation velocity also have a significant effect on encounter satisfaction. However, all assumptions that were expected to moderate the impact of customer participation on encounter satisfaction were rejected. Although the study failed to identify the moderating role, it was clear about the impact on the encounter satisfaction of commitment velocity and customer participation velocity. Applying them to a wider variety of service types provided an opportunity to identify the value of the study, and to broaden the scope of the study suing these variables.

The purpose of this study was to stimulate the online word-of-mouth advertising by developing the concept of word-of-mouth constraint factors and measurement tools in connection with the SNS advertising on social networks. To achieve the objective of this study, this study was conducted in 3 phases. First, the exploratory investigation(target group interview, in-depth interview, and expert interview) was performed to determine the concept and scope of the word-of-mouth constraint based on literature study and qualitative investigation method. Second, the reliability and validity of the measurement questions were verified through the survey in order to refine the developed measurement items. Third, the predictive validity of measurement items was verified by examining the relationship with other major construct concept for which the developed measurement items were different. Based on the results of study, 6 components and a total of 23 measurement questions for those components were derived. Each was called intrapersonal and interpersonal constraint(psychological sensitivity, compensatory sensitivity, and other person assessment), structural constraint(reliability, informativity, and entertainment). We developed the measurement questions related to word-of-mouth constraint based on qualitative study and quantitative study and holistically examined the social and psychological, environmental interruption factors acting as the word-of-mouth constraint factors for SNS advertising in terms of SNS achievements and evaluation from the perspective of word-of-mouth constraint. The results will lead to creation of basic framework for systematic and empirical research on the online word-of-mouth constraint and to achievement of effective SNS word-of-mouth advertising.

Recently, various systems have been developed to support ship navigation safety. In order to verify the usefulness of such a system, it is most ideal to try it on a real vessel, but there are many difficulties. As an alternative, usability verification methods applied with modelling and simulation (M&S) techniques are required such as FMSS, which is closest to reality, is very expansive to construct, and there needs the specialized operator. For this reason, this paper proposes a method to verify the navigation safety support system by modeling and simulation techniques based on the Discrete Event System Specification (DEVS) formalism. As a first step, we designed the navigation simulation architecture based on the SES/MB framework, and details on modelling ship core equipment and navigator agents based on the DEVS. Through this, we are able to implement the navigation simulation system for vessels, and evaluate the effectiveness of navigation safety support elements such as collision avoidance, etc. using developed scenarios.

Blockchain is considered as an innovative technology along with Artificial Intelligence, Big Data, and Internet of Things. However, since the inception of the genesis of blockchain technology, the cryptocurrency Bitcoin, the technology is not utilized widely, not let alone disruptive applications. Most of the blockchain research deals with the cryptocurrency, general descriptions of the technology such as trend, outlook of the technology, explanation of component technology, and so on. There are no killer applications like Facebook or Google, of course. Reflecting on the slow adoption by businesses, we wanted know about the current status of the research on blockchain in Korea. The main purpose of this paper is to help business practitioners to identify the application of blockchain to enhance the competitiveness of their organization. To do that, we first use the framework by Iansiti et al (2017) and categorize the blockchain related articles published in Korea according to the framework. This is to provide a benchmark or cases of other organizations' adoption of blockchain technology. Second, based on the value proposition of blockchain applications, we suggest evolutionary paths for adopting them. Third, from the demand pull perspective of technology adoption for innovation, we propose applicable areas where blockchain applications can be introduced. Fourth, we use the value chain model to find out the appropriate domains of blockchain applications in the corporate value chains. And the five competitive forces models is adopted to find ways of lowering the power of forces by incorporating blockchain technology.

Establishing career goals and making a career choice is the most crucial task for college students. This study aims to identify the motive of college students' career choices and analyze the relationship between career capabilities and career decision-making in order to provide basic materials that can assist college students in the career decision-making process. To do this, a survey was conducted among college students attending a D university in Busan. A total of 326 survey responses were selected for analysis, and path analysis was conducted using SPSS 25 and AMOS 25. The results of the study are as follows. First, intrinsic motivation for career choice and extrinsic motivation for career choice were found to affect career consideration and career management capabilities, respectively, with statistical significance. Second, career consideration and career path management capabilities influenced both concreteness and confidence, which are elements of career decision-making with statistical significance. Intrinsic motivation for career choice and extrinsic motivation for career choice affected concreteness and confidence in career decision-making with career consideration and career management capabilities as parameters. These findings imply that in order to increase the concreteness and confidence in the career decision-making of undergraduate students, it is necessary to strengthen their career consideration and career management capabilities. As the unemployment rate of youths rises and the types and specialization of jobs increase amid uncertainty in the future employment conditions, undergraduate students face increasing difficulties in career decision-making. The results of this research are expected to be used as basic materials for the career decision-making of undergraduate students, which will assists in career path consultation and guidance in universities.

The purpose of this study is, first, to empirically verify the relationship between the influences of the start-up performance and the inherent fear factor of failure on the start-up performance through the preparation of the start-up. Second, this study aims to prove the influence of the moderating effect of social support on the relationship between start-up preparation and the burden of start-up failure. The research subjects were sampled and analyzed by 298 start-ups who are currently starting their own businesses. This study founds that preparation of start-up items, which is a subordinate theory of start-up preparation, had a significant effect on start-up performance, and that anxiety about failure had a significant effect on start-up performance. Using the SPSS statistical program, the hierarchical regression analysis proved the moderating effect of social support in the relationship between star-tup preparation, start-up failure burden and startup performance. Furthermore, the moderating effect of social support among start-up preparation, start-up failure burden and start-up achievement was analyzed, but no significant results were found for start-up failure burden. Besides, the effect of the opposite concept of independent variables on the dependent variables at the same time is to be analysed.

As knowledge management is recognized as an important factor for organizational performance, organizations are increasing their investment in knowledge management policies and technologies. The purpose of this study is to suggest positive and negative causes on the intention to share knowledge through a using knowledge management system(KMS) and to suggest the effect of organizational sharing climate. Research models and hypotheses were presented through previous studies, and 417 samples were obtained through the survey for employees of organizations that adopted a KMS. As a result of the analysis, usefulness and ease of use of the KMS had a positive effect on the intention to share knowledge, and task conflict and ambiguity had a negative effect. The knowledge sharing climate was found to be an antecedent for the technology acceptance model and task stress. In addition, task stress moderated the effect of usefulness and ease of use with the intention to share knowledge using KMS. The results suggested the direction to be pursued at the organizational level for the continuous use of KMS.

COVID-19 has radically changed the behavior of members of society for exchange. In particular, the strong contagiousness of the virus is increasing networking on online platforms while reducing people's networking in the real world. Recently, the metaverse, which strengthened the presence based on 3D technology, is attracting attention from members of society such as individuals and companies. We present a method to improve metaverse utilization from the perspective of organizations and employees who have introduced metaverse for work. In other words, we check the effect of metaverse social function and telepresence on the employee's intention to offer support by improving the trust of the metaverse participants. We obtained samples through questionnaires targeting employees of organizations that introduced metaverse to their work, and verified the research hypothesis by applying the structural equation model. As a result, social interactivity, reciprocal favor, and telepresence of metaverse partially affected metaverse trust (platform, peer, organization), and metaverse trust increased the intention to offer support. Our study suggests a strategic direction to improve the metaverse utilization and exchange level of employees of organizations who want to use the metaverse for business.
