We look at the business model development of a fan community platform 'Weverse' from two-sided platform (TSP) to multi-sided platform (MSP) and investigate its platform business model. From the Rocket Model's theoretical perspective, the results reveal that Weverse firstly focuses on inviting artists as many as possible starting from BTS, then attracts new artists' fans naturally. For success of this TSP, it forms MSP, 'Weverse Shop' to meet two sides' relevant needs timely and filtered. In third stage of connection, various partnerships are attempted in terms of open platform strategies. For instance, by combining 'VLive' and Weverse, Naver's fan platform business is transferred to Weverse. For core transaction through direct and indirect monetization, several cobranding activities are tried. Lastly, regarding optimization, newly born Weverse being launched in the first half of 2022 is supposed to create further synergies with Naver's R&D capabilities in data, AI, and other technologies like metaverse platform 'ZEPETO' which already sells clothing items of Weverse artists.

최근 전 세계가 COVID-19 팬데믹을 겪으면서 실세계 속 사회 및 문화 활동이 온라인 등 비대면으로 옮겨지며 비대면 사회활동 및 가치 창출을 위한 메타버스 플랫폼들이 생겨나기 시작하고 이들의 사회적 파급력 및 가치가 높아지고 있다. 메타버스 플랫폼에서 수행되는 사회 및 문화 활동의 가치가 높아짐에 따라 메타버스 플랫폼은 해커에게 '저비용 고효율'적인 공격 대상이 되어 메타버스의 안전성 및 보안성 이슈가 화두가 되고 있다. 본 논문에서는 메타버스 플랫폼을 대표하는 'ZEPETO^TM', 'Roblox^TM', '어스2^TM' 등의 메타버스 플랫폼에서 발생한 보안사고의 공격 지점 및 연관된 공격 체인을 조사하고 메타버스를 구성하고 있는 핵심 시스템 요소에 대한 위협벡터를 도출하였다. 본 연구 수행에서 활용한 방법론은 메타버스 플랫폼뿐만 아니라 신규 소프트웨어 기반 플랫폼이 출시될 때의 위협벡터를 도출하고 그에 따른 보안대책 수립을 위한 활용으로 사용될 수 있다.

The combination between metaverse and non-fungible token (NFT), which opens up new opportunities for the media industry, raised expectations for a new economic system and business model. Of course, last year, various institutions and researchers continuously introduce representative metaverse services and business strategies such as Roblox, Fortnite, and ZEPETO. However, as 2022 progresses, the reaction to the metaverse is tepid than expected. Search volume on Google has been continuously decreasing. Furthermore, skepticism, regarded as one of the special phenomena caused by the coronavirus disease 2019 pandemic, is expanding since December 2021. Nevertheless, analysis or contemplation of a new business model related to the metaverse, which is still ongoing, is essential for those who must prepare for the future. The reason is that even if without being activated now, advanced preparation can help when various problems arise. In this study, we look at the metaverse and NFT biz models and estimate a picture of the future. In other words, the social and economic problems that may arise when the business model is expanded are summarized, and technical and policy measures are derived as solutions.

To enhance safety in dangerous situations, it is essential to provide practice-oriented safety education. However, direct experiences can be limited, and thus, metaverse-based safety education is emerging as an alternative. In this study, we analyzed the first official metaverse safety education program of the Korea Ministry of Education, mainly focusing on its title, objectives, content, and results using the Revised PRISMA framework. The program concentrates on "life safety" for "fire safety," "disaster safety" for "earthquake safety," and "first aid" for "abrasions, burns, fractures, cardiopulmonary resuscitation, and the use of AED." We classified the objectives of the entire program and its three sub-programs, and identified the knowledge, main practice tasks, and their results. The aim of this study is to promote an understanding of the main cases of national-led metaverse safety education and infer the practical safety education contents emphasized to Korean school-age students.

Education in radiology involves a large portion of practical training, and it is difficult to conduct it through non-face-to-face online education. In this study, we utilized the Metaverse platform, which can replace hands-on education, to implement a practice room that is difficult to access through non-face-to-face classes into a virtual world, and then evaluated the satisfaction of learners after the practice class, the practicality of the Metaverse platform class, and the future orientation of the curriculum. I wanted to find out. Using the metaverse platforms ZEPETO (Build It) and ZEP (ZEP), the S University radiology department lab was implemented into a virtual world and used for students' classes. A total of 50 students were surveyed twice, divided into pre- and post-surveys, and all questions used a 5-point Likert scale. As a result of the study, satisfaction was low at 2.32 for education without using Metaverse virtual space, while education using virtual space was very high at 4.16. As a result of the analysis, the satisfaction level of the new education system and the practicality of the Metaverse platform classes are very high, and it is believed that it will be a more effective education platform when conducting additional education such as app explanations in the future.

Metaverse is attracting attention as the development of virtual environment technology and the emergence of untact culture due to the COVID-19 pandemic. In this study, by analyzing users' reviews on the "Zepeto" application, which has recently attracted attention as a metaverse service, we tried to confirm changes in the requirements for the metaverse after the COVID-19 pandemic. To this end, 109,662 reviews of "Zepeto" applications written on the Google Play Store from September 2018 to March 2023 were collected, topics were extracted using LDA topic modeling technique, and topics were analyzed using the Causal Impact technique to examine how topics changed before and after based on "March 11, 2020" when the COVID-19 pandemic was declared. As a result of the analysis, five topics were extracted: application functional problems (topic1), security problems (topic 2), complaints about cryptocurrency (Zem) in the application (topic 3), application performance (topic 4), and personal information-related problems (topic 5). Among them, it was confirmed that security problems (topic 2) were most affected by the COVID-19 pandemic.

In the COVID-19 pandemic era, non-contact services were demanded and the use of extended reality and metaverse services increased rapidly in various applications. In this paper, we analyze Gather.town, ifland, Roblox, and ZEPETO metaverse platforms in terms of user interaction, avatar-based interaction, and virtual world authoring. Especially, we distinguish interactions among user input techniques that occur in the real world, avatar representation techniques to represent users in the virtual world, and interaction types that create a virtual world through user participation. Based on this work, we highlight the current trends and needs of human-metaverse interaction and forecast future opportunities and research directions.

This study investigated effects of metaverse experience on avatar fashion item benefit sought and the impact of fashion item benefit sought on fashion item purchase behavior. An online survey was carried out in the last year targeting male and female consumers aged 15 to 39 years who had purchased avatar fashion items from 'Zepeto'. A total of 363 responses were analyzed in this study. Results are as follows. First, four factors of metaverse experience were derived: 'entertainment experience', 'escape experience', 'adventure experience', and 'relationship experience'. Four factors of avatar fashion item benefit sought were derived: 'trend/brand sought', 'situation suitability sought', 'individuality sought', and 'ideal appearance sought'. Second, all four factors of metaverse experience were found to significantly affect the benefit of trend/brand sought. It was found that entertainment, adventure, and relationship experiences, excluding escape experiences, had significant effects on situational suitability sought. In addition, it was confirmed that entertainment and adventure experiences had significant effects on individuality sought and ideal appearance, respectively. Third, it was found that the trend/brand sought had a significant effect on metaverse usage time and purchase amount and that the situational suitability sought influenced the number of avatar fashion items purchased.

Purpose: This study aims to examine the opportunities in the food industry in the context of non-fungible tokens (NFTs) and the metaverse. The metaverse expands offline experiences into a virtual space and provides users with the advantage of overcoming the limitations of physical space. Research design, data and methodology: With the development of various contents based on advanced technology, the metaverse is becoming popular among the MZ generation (comprising millennials and Gen Zs), who are skilled at navigating digital platforms. Moreover, the previously entertainment game focused service has expanded to the business field after COVID-19; activities on the metaverse are now making space for economic value creation. I examined the recent global trends in the context of NFTs and the metaverse as well as the existing cases in Korea. Results: Globally, gaming and performance platforms such as Roblox, Fortnite etc. are still concentrated in the entertainment industry. However, as shown by ZEPETO and ifland in Korea there are many opportunities in the retail and food industries. Conclusions: We analyzed the ecosystems of the retail and food and beverage sectors, where the metaverse will be useful in the future, and have suggested the implications of the opportunities provided by the metaverse.
