As non-face-to-face activities have become commonplace, online video conferencing platforms have become popular collaboration tools. However, existing video conferencing platforms have a structure in which one side unilaterally exchanges information, potentially increase the fatigue of meeting participants. In this study, we designed a video conferencing platform utilizing virtual reality (VR), a metaverse technology, to enable various interactions. A virtual conferencing space and realistic VR video conferencing content authoring tool support system were designed using Meta's Oculus Quest 2 hardware, the Unity engine, and 3D Max software. With the Photon software development kit, voice recognition was designed to perform automatic text translation with the Watson application programming interface, allowing the online video conferencing participants to communicate smoothly even if using different languages. It is expected that the proposed video conferencing platform will enable conference participants to interact and improve their work efficiency.

This study was conducted to investigate the motives and effects of artists and teachers who participated in the ' Explore Life through Art' support project for school education by theme of culture and arts. As a result of research analysis using online survey and in-depth interview research method, it was found that both intrinsic and extrinsic motives have a complex effect on artists and teachers' motivation to participate in the project. As for the effectiveness of participating in the project, the trust between artists and teachers and the contribution of education were positive, but the trust and satisfaction with the institution were negative. In order to increase the effectiveness of the project, it is required to improve the operation and management of the operating institution. Motivation and effectiveness of project participation are important factors in improving the quality of a project, and it is hoped that this study will serve as a basis for practical discussions on the role of operating institutions and projects.

An increasing number of studies have examined the effects of corporate social responsibility (CSR) activities on corporate financial performance (CFP) in the service industry. However, the extant literature does not provide comprehensive insights into the conditions on which the CSR-CFP link relies. In this study, firms' marketing communication capability (MCC) is introduced as an important contingency variable, which determines the effects of CSR on the corporate financial performance, in the context of restaurant businesses. Multiple year data on the spending of public restaurant chains on different media are collected, and MCC is subsequently measured using the data envelope analysis. Then, a test is conducted to prove whether MCC moderates the relationship between CSR and firm financial performance. The empirical results support the hypothesis that MCC strengthens the effect of CSR on CFP. Through the findings, this research provides several interesting and important implications to the literature and managers of service firms.

National support for use of IPTV in school has increased for the purpose of enhancing public education. As a convergence media, IPTV is expected to create a better and more successful learning experience with individualized content and advanced technology. While the potential benefits of IPTV have been discussed in different perspectives, we cannot fully benefit from new media without careful preparation and pedagogical consideration. Therefore, purpose of this study was to investigate educational use and applicability of IPTV in Korea. First, it redefines the concept and characteristics of IPTV in an educational context. Second, it identifies the main issues and considerations in practice. Lastly, the paper discusses guidelines for future tasks to facilitate the educational use of IPTV in terms of educational application, technological issues (e.g., LMS, set-top box), and content development.

In the 21^st century, the growing use of information and communication technologies (ICTs) and social media platforms has influenced our way of life, including international diplomacy. With the use of new interactive communication technologies such as WhatsApp, Twitter, Facebook, Instagram, video sharing website, blogs, and other social media networks, digital diplomacy has become an active diplomatic mode in modern society and plays an increasing important role in international relations. Although Indonesia has gradually realized the pivotal role of internet diplomacy and recently put it into practice, it is still lagging far behind. This paper will examine how Indonesia conducts its diplomacy in the new era of digital world. How far and in what ways does the Indonesian government make use of digital technology to conduct its diplomacy? What opportunities and challenges are confronted to develop digital diplomacy? How does it navigate diplomacy in the digital age? Unless Indonesia embraces new channels and methods of diplomacy, its foreign policy implementation may not run optimally to support its aim of attaining its objectives in the international stage.

In this paper we used classification algorithms on social networking. We are proposing, a new classification algorithm called the improved Decision Tree (IDT). Our model provides better classification accuracy than the existing systems for classifying the social network data. Here we examined the performance of some familiar classification algorithms regarding their accuracy with our proposed algorithm. We used Support Vector Machines, Naïve Bayes, k-Nearest Neighbors, decision tree in our research and performed analyses on social media dataset. Matlab is used for performing experiments. The result shows that the proposed algorithm achieves the best results with an accuracy of 84.66%.

Objective: The purpose of the present study was to examine the changes in the body perception of young children using a short-term longitudinal design, then to investigate the factors related to their body perception. Methods: Participants were 65 preschool children and their mothers that were recruited from five institutions. An 11-month, two-time point longitudinal design was used in which children were interviewed individually to examine the changes in body perception. At the second time point, children were assessed with an additional measure to investigate self-esteem, and their mothers also reported on maternal factors and children's media experience through a questionnaire. Data were analyzed by paired t-test, independent t-test, correlations and ANOVA. Results: The results showed a significant decline of children's negative body perception over time. Children's media experience was positively correlated with negative body perception. Mothers whose children showed higher body mass index (BMI) sent more verbal messages about their child's weight reduction. In addition, children's negative body perception was positively correlated with physical self-esteem. Finally, there was a significant difference in only the physical self-esteem according to the level of children's body perception. Conclusion/Implications: The findings would suggest theoretical and practical implications to support intervention and education programs to improve the body image of young children.

Social media which support to share information and communicate between online users have recently won great popularity. Of the various social services blogs have played an active role as a community in sharing delivering and exchanging information among individual users who have share similar opinions hobbies and preferences. Based on this cultural phenomenon some companies often take advantage of blogs as a marketing tool to strengthen their public relations or deliver particular information to their costumer. This study is designed to classify fashion-related blogs and define the characteristics of each type expecting significant influences on future studies on this topic. We selected 50 fashion-related blogs as subjects including 25 Korean blogs and the same number of international blogs, defined their characteristics and classified them into four different types. As the result we found that there are apparent differences between the four types of blogs: "Individual taste" blogs which noticeably reflect bloggers' own preference "Trend leader" blogs in which the bloggers intend to be trend leaders beyond expressing their preference "Fashion media" blogs which plays a significant role as a magazine by providing various information concerning fashion for costumers and "Sales promotion" blogs which are used as promotional materials to attract customers by providing product reviews or advertisements.

A knowledge-based society values creative and independent individuals. This study depicts operational approaches to the effective utilization of school libraries as teaching/learning media center in order to support independent learning in relation to the way in which constructivist teaching-learning(CTL) improves learners' self-learning abilities. The result of this study seems to imply that self-learning based on constructivism is possible only when school libraries are managed as teaching/learning media centers and that the more variety there is in learning materials and when more direct interaction exists, there is more creativity and self-learning abilities are achieved in the learning process.

Works were focused on back pressure characteristics of ceramic fiber filter on DPF (Diesel Particulate Filter) system and experiments were performed to select appropriate filter which can filter particulates. Filters were installed on metal -support tube which has openings for exhaust gas flow. Ceramic fiber filters with high specific surface area and adequate high temperature strength are commercially available for filtration of diesel particulates and in -situ hot regeneration. Thus, ceramic blanket and ceramic board which are used as insulating media were applied to filter and filtration apparatus was installed on exhaust gas line connected to 2.0 L diesel engine. Alternating filter structure to adapt DPF system, collection efficiency test of diesel particulates was measured. In case of ceramic blanket, pressure drop was low, caused by the destruction of soft structures. Also, particulate collection efficiency was decreased depending on loading time. In case of ceramic board, structure design was altered to reduce back pressure on DPF system. Structure design was altered to induce Z-flow by making 10 mm and 5 mm holes on the surface of media. Alteration of 5 mm hole showed that media have low back pressure but particulate collection efficiency was 77%, while 10 mm hole showed that of 90%.
