The purpose of this study is to verify the mediating effect of interaction among learners in a Web Based Collaboration Learning (WBCL) environment. 254 Korean college students served as test subjects and during the 4 weeks of research period, they studied the Test of English for International Communication (TOEIC) in a web-based collaborative learning system. The interaction between learners was looked into by categorizing the concept into task oriented information sharing activities and relationship oriented communication activities and analyzing the causal relationship between the two activities. Learning performances were measured in individual level. The results are as follows. First, task oriented information sharing activities effect positively on relationship oriented information sharing activities. Second, the managerial characteristics of WBCL had a positive effect on interaction between learners but the systematic characteristics had partial influence on interaction between learners. Third, the interaction between learners completely interconnects the managerial characteristics of WBCL and learning performance but partially interconnects the systematic characteristic of WBCL and learning performance. In conclusion, this study implies that managerial and systematic characteristics of WBCL should be considered on the preferential basis for the WBCL to become successful and interactive activities such as information sharing and communication should be encouraged to be active from a small-size WBCL perspective.

Purpose: The purpose of this study was to investigate the mediating effect of optimism on the relationship between grit and learning flow in nursing college students. Methods: Structured self-reported questionnaires were used to measure grit, optimism and learning flow. The study was conducted on 200 nursing students in P, U and J cities between September 1 and September 20, 2020. The data were analyzed using a t-test, one-way ANOVA, Pearson's correlation coefficients and hierarchical multiple linear regression with SPSS/WIN 23.0. Results: Significant relationships were found between learning flow and grit (r=.60, p<.001), between learning flow and optimism (r=.42, p<.001), and between grit and optimism (r=.42, p<.001). Additionally, optimism had a partial mediating effect on the relationship between grit and learning flow (Z=3.11, p<.001). Conclusion: These results indicate that interventions to increase the level of grit along with optimism is necessary in order to increase the level of nursing college students' learning flow.

교육기관들은 e-Learning이 지속적으로 교육에서 중요한 역할을 하고 있으며 오프라인 교육에 대한 대안으로 증가되었기 때문에 e-Learning 품질관리를 위한 가이드라인을 제시하고 있다. 또한 e-Learning이 전통적인 교수-학습 모델과 항상 일치하지는 않으며, 서비스 설계와 구현에서 더 많은 주의가 필요하기 때문에 현재까지 다양한 e-Learning 품질관리 기법들이 개발되고 있다. 그러나 현재의 학습 객체 중심의 e-Learning 품질관리는 부분적이고 정적인 관리를 사용하기 때문에 많은 문제점을 가진다. 본 논문에서는 인과지도(CLD: Causal Loop Diagram)를 이용한 동태적인 e-Learning 품질관리를 제안하였다. 제안 방법은 기존 방법보다 더 효율적이며 e-Learning에서 관리적인 문제들에 대해서도 중요한 전략을 제공한다.

Distance teaming systems have become popular tools for teaching and learning. The purpose of this study is to analyze influence of instructor factors and media richness on student's intention th use and performance in distance teaming. We used TAM as a theoretical foundation to explain student's behavior. The model was tested using LISREL analysis on the sample of 246 users rho have experience with the distance teaming systems. The results show that instructor factors such as luぉ style and attitude have partial effects on perceived usefulness, ease of use and media richness. In addition, results also show that both TAM variables and media richness strongly predict intention In use of the distance loaming system Finally, the usage intention has a positive effect on teaming performance. Implications of these findings are discussed for researchers and practitioners.

In this study, we investigate the relationships among organizational market orientation, learning orientation, information technology(IT) support for firm resource, IT support for strategy, and balanced scorecard(BSC) performance in export firms. The development of the research model is based on the empirical studies of strategy and resource-based view. The data from the survey was analyzed using Partial Least Squares(PLS). The results from the empirical model suggest that IT support for firm resource is effected by market orientation and learning orientation. And, IT support for strategy is enhanced by IT support for firm resource. Finally, BSC performance of export firms is effected by IT support for strategy.

Recent trends in deep reinforcement learning (DRL) have revealed the considerable improvements to DRL algorithms in terms of performance, learning stability, and computational efficiency. DRL also enables the scenarios that it covers (e.g., partial observability; cooperation, competition, coexistence, and communications among multiple agents; multi-task; decentralized intelligence) to be vastly expanded. These features have cultivated multi-agent reinforcement learning research. DRL is also expanding its applications from robotics to natural language processing and computer vision into a wide array of fields such as finance, healthcare, chemistry, and even art. In this report, we briefly summarize various DRL techniques and research directions.

Why does e-Learning service for individuals remain in the early development stage? To find the answers of this question, we adopted usefulness and intention to continued use as dependent variables based on technology acceptance model and inferred convenience, cost-effectiveness, social presence, interactivity, concentration, and procrastination as independent variables based on literature review and interview with e-Learning users. Convenience and cost-effectiveness of e-Learning tend to enhance usefulness and/or intention to continued use, while lack of social presence, interactivity, and concentration of e-Learning and academic procrastination tend to hinder usefulness and/or intention to continued use. To prove this research model, we used a data set collected from the survey. The respondents of survey were the undergraduate students who used voluntarily e-Learning. Data analysis was conducted using 275 respondents by partial least square. The analysis result of causal relation indicated that convenience and cost-effectiveness influenced both usefulness and intention to continued use, and that cost-effectiveness and concentration influenced only intention to continued use. But, interactivity and procrastination did not influence usefulness and intention to continued use.
