This study explored the factors that influence elementary school teachers' intention to use an artificial intelligence (AI) math learning system and analyzed the interactions and relationships among these factors. Based on the technology acceptance model, perceived usefulness for math learning, perceived ease of use of AI, and attitude toward using AI were analyzed as the main variables. Data collected from a survey of 215 elementary school teachers was used to analyze the relationships between the variables using structural equation modeling. The results of the study showed that perceived usefulness for math learning and perceived ease of use of AI significantly influenced teachers' positive attitudes toward AI math learning systems, and positive attitudes significantly influenced their intention to use AI. These results suggest that it is important to positively change teachers' perceptions of the effectiveness of using AI technology in mathematics instruction and their attitudes toward AI technology in order to effectively adopt and utilize AI-based mathematics education tools in the future.

The most important points in the field of entrepreneurship research are new venture creation and behaviors for start-up venture. Most of past researches are limited to the formation of entrepreneurial intention, and researches on entrepreneurial activities, specifically nascent entrepreneurial behavior, have not been studied well. In this study, we view entrepreneurial process as gestation process from entrepreneurial intention to nascent entrepreneurial activities, and identify the moderating effects of cognitive style, which is the way of thinking about the information in entrepreneurial process. In addition, we find the moderating effects of cognitive style on the relationships between perceived barriers and support in environmental factors and nascent entrepreneurial activities. Subjects of this study are potential entrepreneurs. So we selected university students who are taking venture start-up course, conducted a survey, collected 367 questionnaires. In statistical test, we applied PLS-SEM for testing hypotheses because CB-SEM is too sensitive to test more than two moderating effects in th research model. As a result of the analysis, it was found that entrepreneurial intention, cognitive planning style, cognitive creative style, perceived support had a significant effect on nascent entrepreneurial behavior. The results of the analysis of the moderating effects of cognitive style which are the hypotheses in the research are as follows. First, the cognitive planning style did not have a significant moderating effect on the relationship between entrepreneurial intention and nascent entrepreneurial activities. Second, in the relationship between perceived barriers and nascent entrepreneurial activity, cognitive planning style did not have significant moderating effect, and cognitive creating style had significant negative moderating effect. Third, in the relationship between perceive support and nascent entrepreneurial activity, cognitive planning style had significant positive moderating effect, and cognitive creating style did not have significant moderating effect.

This study analyzed the positive effect of perceived over-qualification on creative behavior, moving away from the perspective of previous studies that mainly focus on the negative effects of perceived over-qualification. A survey of 282 employees in the financial industry in China was conducted and the structural equation model analysis was used. As a result of the analysis, perceived over-qualification has a positive effect on employees' creative behavior, the fact that perceived over-qualification has a positive effect on creative behavior has enriched research on the effect of perceived over-qualification th some extent. In addition, theoretical and practical implications were provided by demonstrating the relationship between creative behavior, emotional exhaustion, job crafting, and perceived organizational support. It was measured in the terms of subjective over-qualification, Discussions on over-qualified recognition remain at the individual level of employees, and future studies need to study the collective phenomenon of over-qualified recognition at the team level or organization level.

The pharmaceutical industry is experiencing a productivity crisis with a low probability of success despite a long period of time and enormous cost. As a strategy to solve the productivity crisis, the use cases of Artificial Intelligence(AI) and Bigdata are increasing worldwide and tangible results are coming out. However, domestic pharmaceutical companies are taking a wait-and-see attitude to adopt AI platform for drug research. This study proposed a research model that combines the Value-based Adoption Model and the Innovation Resistance Model to empirically study the effect of value perception and resistance factors on adopting AI Platform. As a result of empirical verification, usefulness, knowledge richness, complexity, and algorithmic opacity were found to have a significant effect on perceived values. And, usefulness, knowledge richness, algorithmic opacity, trialability, technology support infrastructure were found to have a significant effect on the innovation resistance.

This study explored the longitudinal relationships between school life adjustment and the parents' neglect/abuse as perceived by children according to gender. The participants were 5th and 6th grade children and the instruments were parents' neglect/abuse scale and school life adjustment scale. Using Korea Youth Panel data of Child Youth Policy Institute of Korea, 5th and 6th grade data were analyzed. The results were as follows: Neglect/abuse as perceived by children were different according to their gender and grade. Children who had perceived more parents' neglect/abuse were more likely to have difficulty in school life adjustment. The results of this study suggest that the appropriate interventions for the parents' neglect and abuse is needed by showing the stability of the child's perception of the parents' neglect and abuse during the 5th-6th grade.
