수동적 온톨로지 구축은 해당 도메인의 지식을 가진 전문가가 필요하고, 시간적인 소모가 크다. 또한 완성된 온톨로지의 수동적인 지속적 개선은 상당한 비용을 초래할 수 있다. 그래서 온톨로지의 자동 구축과 지속적 자기 개선 방법이 하나의 해결책이 될 수 있을 것이다. 따라서, 이 논문에서는 기계 학습을 통한 온톨로지 구축의 자동화 방법과 지속적 자기 개선 모델을 소개하고자 한다.

In this study, we surveyed 184 participating participants in the golf lesson program. The motivation, self-efficacy, and intention to participate were surveyed. First, the multiple regression analysis of participation motivation and self-efficacy showed that behavior self-efficacy had a significant effect on external manifestation and socialization, whereas maintenance self-efficacy was related to technology development/achievement, enjoyment, A significant influence was found. Second, regression analysis of participation motivation and participation persistence intention showed that only enjoyment factor explains meaningfulness of participation persistence intention. Third, regression analysis of self-efficacy and participation persistence showed a significant effect on both behavior and maintenance factors.

COVID-19 is forcing people to minimize face-to-face networking activities between members of society, and they are increasing their use of online platforms. In particular, interest in the metaverse, a virtual community with enhanced realism, is growing. Specifically, this study suggests a mechanism to improve the intention to continuous use of metaverse users by using the self-determination theory, and confirms that trust between metaverse members moderates the relationship between self-determination and intrinsic motivation. We obtained 353 samples through a questionnaire targeting those who have used metaverse and verified the hypothesis through structural equation modeling. As a result of the analysis, individual self-determination of the metaverse formed intrinsic motivation such as identification and enjoyment, which affected the intention to continue use, and the trust of metaverse members partially moderated the relationship between self-determination and motivation. The result contributes to the sustainability of the metaverse platform by suggesting an approach to users and the environment to improve the intention of continuous use of metaverse.

This study looked at what factors lead to continuous participatory intention of online childrearing community. Trust, reciprocity and perceived security from the perspectives of community attributes and reputation motivation, information motivation, enjoyment motivation and self-monitoring from the users' perspectives were conceived as determinants that might have influences on continuous participatory intention of online childrearing community. It were also empirically tested whether they affect continuous participatory intention of online childrearing community. The moderating effect of self-monitoring was examined, too. In order to collect data, online questionnaires were conducted to women whose ages were 20-49 years old and joined online childrearing community. Their responses were analyzed with a regression analysis. The findings showed that trust, reciprocity and information motivation have influences on continuous participatory intention of online childrearing community. The moderating effect of self-monitoring between reciprocity and continuous participatory intention was also found.

The purpose of this study was to examine the relations and analyze the mediation effect that exists between the feedback types by professors of university physical education and self-efficacy and sports continuance. The sampling method was used to survey physical education university students from three different universities located in the Greater Seoul Metropolitan Area. 309 samples were ultimately selected as valid samples. Data processing was carried out by using SPSS 18.0 and AMOS 18.0. The fidelity of the whole model was assessed through this process and then the theory was tested. The results were as follows. Firstly, if the perceived feedbacks by the professor were complimentary/encouragement and performance knowledge/positive nonverbal feedbacks it had a positive effect. Negative nonverbal perceived feedback had a negative effect forecast. Secondly, complimentary/encouragement perceived feedbacks by the professor did not have a meaningful impact on sports continuance index. Performance knowledge/positive nonverbal feedback resulted in static effect while negative nonverbal feedback had a negative effect. Lastly, self-efficacy served a meaningful mediation role in the relation between negative nonverbal feedback by the professor and sports continuance.

With a recent rise of various chatbot services, this study attempts to explore the role of chatbot users'' psychological characteristics by applying the self-determination theory. In particular,this study investigates (a) the relationship between chatbot users' psychological needs(perceived autonomy, perceived competence, perceived relatedness) and user satisfaction, continuous intention to use, and (b) the moderating effect of chatbot type and user motivations. Based upon a survey, the results revealed that perceived autonomy, competence, and relatedness had significant positive effects on user satisfaction and continuous intention to use. The results also confirmed that the user satisfaction had a significant positive effect on the continuous intention to use. The moderating effect of social and relational motivation was found between perceived autonomy, competence, relatedness and user satisfaction. The implications are discussed for furthering the development of chatbot services.

The purpose of this study is to study the mediating verification of self-efficacy in the effect of self-management of hair beauty experts on job performance and beauty continuity intention. The subjects of the study were surveyed and used for analysis of 256 beauty experts working as hair beauty experts in Seoul and Gyeonggi Province. The SPSS 28.0 and AMOS 28.0 statistical package programs were used for the analysis method, and descriptive statistics of mean, standard deviation, kurtosis, skewness, confirmatory factor analysis and reliability analysis, correlation, and mediating effect analysis were analyzed using bootstrapping techniques. The results of the study showed that the self-management of hair beauty experts had a significant positive (+) effect on self-efficacy, job performance, and intention to continue beauty. The self-efficacy of hair beauty experts had a significant (+) effect on job performance and beauty continuity intention. It was confirmed that there was a mediating effect of self-efficacy in the relationship between self-management and job performance of hair beauty experts. The statistical significance level is p<.It was analyzed by setting it at the level of 05.

Focusing upon the post-adoption stage of IS, this study reasoned that IS users' personality is one of major influencing factors of continuous IS usage intention and empirically examined how the degree of continuous IS usage intention is variable according to the IS users' personality types classified based on MBTI(Myers Briggs Type Indicator). In order to validate the research model and hypotheses, this study made a field survey of 330 IS users and statistically analysed response data. The results of empirical analyses showed that the intent of continuous IS usage was affected by self-efficacy of IS; and self-efficacy by self-leadership of IS; and self-leadership by IS user' personality type and expectation confirmation. That is, it was found that IS users' personality type and three intervening variables(expectation confirmation, self-leadership and self-efficacy) were significant predictors of the intent of continuous IS usage. This study is thought to be contributive to providing the theoretical basis of finding IS success factors in the post-adoption stage and the practical guideline for effective personnel management relevant to IS implementation.
