  • 적응적 웹기반 기법에서 학습자의 반응이나, 탐색 행동의 근본적인 원인이 되는 학습 동기, 지각 등에 대한 판단을 정확히 할 수 없기 때문에, 학습자에게 완전히 적응적인 수업 환경을 조성해 주는 데는 한계가 있다. 이러한 한계를 극복하기 위한 대안으로 학습자간 상호작용이나 협동 학습을 지원하는 웹기반 교수 시스템이 제안되고 있다. 본 논문에서는 웹기반 환경에서 학습자들간의 협동학습을 효과적으로 지원하는 적응형 교수 시스템을 제안한다. 본 시스템은 협동학습 공간에서 주어진 과제를 수행하기 위해 발생되는 학습자들의 대화와 서로간의 상호작용을 분석하여 적절한 조언을 제공함으로서 협동학습이 효과적으로 이루어 질 수 있도록 지원한다.

  • The attitudes and interests of parents toward having better interrelationships with their children will have the greatest positive impact on the mental health of a growing child. The purpose of this study is to elicit how to effectively use bibliotherapy to promote interaction between parents and children. Based on action research methods, and in order to achieve the research objectives, the parent-child bibliotherapy target program was divided into two "lanes" and a total of 25 iterations were performed or observed for every process in detail and with different technologies. According to the result, the bibliotherapy helps improve parent-child interaction.

  • The purpose of this study is to examine the effects of the interdependent partnership between liner shipping companies and port-related service firms on the service quality and transaction performance. The empirical analysis found that sharing information and mutual trust of partnership factor positively affected service quality of the port-related service firms, but the communication had negative effects on it. The interdependence had the interaction effect between the partnership and the service quality. Also, the service quality affected satisfaction of transaction and re-purchasing of the shipping companies. This study shows that the partnership to be formed mutual dependent relationship between shipping companies and the port-related firms improve the service quality of shipping service network and enhance transactional satisfaction of both parties.

  • In this study, the effects of reciprocal peer tutoring strategy on science achievement, science learning motivation, and self-esteem were investigated. Three classes of eighth graders (N=94) at a coed middle school were sampled for the study. They were divided into the comparison group, the cooperative learning (CL) group, and the reciprocal peer tutoring (RPT) group. Students were taught about the separation of mixtures for 13 class hours. Mid-term science examination scores were used as a blocking variable. The two-way ANCOVA results revealed that there were no significant differences among the three groups in the science achievement test, although the scores of the RPT group were higher than those of the comparison group. In all the subtests of the science learning motivation questionnaire, the scores of the RPT group were significantly higher than those of the comparison group. The scores of the RPT group were significantly higher than those of the other groups especially in the confidence part of the science learning motivation questionnaire. In the self-esteem test, the low achievers in the RPT group scored significantly higher than those in the CL group.

  • The effectiveness of joint operations depends on Jointness based on interoperable elements of participating forces. Many specialists have actively done research studies on interoperability measurement models with the goal of straightforward way of measuring and then have improved the interoperability of elements based on DOTMLPF-p (Doctrine, Organization, Training, Materiel, Leadership & Education, Personnel, Facilities, Policy) in the forces. After the survey of 16 interoperability measurement models, we have concluded that most of them applied only a small portion of DOTMLPF-p elements explicitly or all portions of DOTMLPF-p elements implicitly. In this study, we propose a conceptual interoperability measurement model for applying all DOTMLPF-p elements explicitly. And it can evaluate not only the level of interoperability among forces but also level of jointness for joint operations.

  • The purpose of this study is to establish smart signage in a certain space and to analyze not only media ingestion and advertising inducement as well as any information (high vs. low vs. low) and flow level And the memory effect related to whether or not to remember. The results of this study show that the higher the interaction level and the higher the engagement level, the higher the advertising engagement is. In addition, media involvement was high when interaction level was low and flow level was high. Finally, if the level of interactivity is low and the level of flow is high, then non - valued attribution information is more likely to be recalled than the comprehensive evaluation information. If the interaction of smart signage is high and the flow of users is low, Recalled more recall information. In the future, detailed strategies for enhancing user flow will be needed rather than a strategy for unconditional enhancement of interaction in smart signage strategy.

  • This study examines how interactivity and usage mode of a chatbot interface affects user experience. Chatbot has rapidly been commercialized in accordance with improvements in artificial intelligence and natural language processing. However, most of the researches have focused on the technical aspect to improve the performance of chatbots, and it is necessary to study user experience on a chatbot interface. In this article, we investigated how 'interactivity' of an interface and the 'usage mode' referring to situations of a user affect the satisfaction, flow, and perceived usefulness of a chatbot for exploring user experience. As the result, first, the higher level of interactivity, the higher user experience. Second, usage mode showed interaction effect with interactivity on flow, although it didn't show the main effect. In specific, when interactivity is high in usage mode, flow was the highest rather than other conditions. Thus, for designing better chatbot interfaces, it should be considered to increase the degree of interactivity, and for users to achieve a goal easily through various functions with high interactivity.

  • This study examines the economic effects of a developed country's minimum quality standards (MQS) and mutual recognition agreements (MRAs) between countries. Based on the results of such analysis, it also considers the optimal MRA strategy for South Korea. For this purpose, the paper constructs a simple three-country model in which the representative firms in each country supply differentiated goods to the developed country market. The analysis results are as follows: First, the rise in the MQS of a developed country intensifies the competition level, reduces the profits of all firms, and raises the developed country's consumer surplus. In addition, if one of the firms exits the market due to the MQS, competition is relaxed, and the profits of the remaining firms increase. Second, countries subject to MQS can improve their social welfare through the MRAs; thus, it is essential to utilize them strategically. In the case of South Korea, the optimal situation is to have an MRA with the developed country or for all three countries not to have any MRA.
