This study aims to explore the status and motives for using avatars and digital fashion items in the metaverse and to examine consumers' purchase satisfaction and future purchase intentions. We intend to provide implications for the development of avatars and fashion items, and the direction of the fashion industry and clothing education. For this purpose, the purchasing status, consumer motives for using avatars and digital fashion items, purchase satisfaction, and future purchase intentions were investigated, through a survey with 149 consumers aged 19 years or older, with the experience of using avatars. The results are as follows. First, the percentage of avatar ownership was high among women aged between 19 and 29, and those with low or high incomes. The younger group was more likely to make mobile phone purchases than the older group, and the older group was more likely to use credit cards. Even those respondents who owned avatars did not purchase frequently or spent a lot on items. On the other hand, in the case of fashion item purchases, the group spending more than 8,000 won was aged between 19 and 29, and the frequency and amount of purchases increased as income increase. Second, among the motives for using avatars and fashion items, the pursuit of pleasure had the greatest influence, and men paid more attention to self-expression through avatars than women. Third, the motive for vicarious satisfaction influenced purchase satisfaction, and the factors that influenced future purchase intention were vicarious satisfaction and stress relief. The results of this study suggests that avatars and fashion items should be developed considering factors that can relieve stress for all age groups, create a sense of unity among metaverse users, and provide satisfaction in a virtual world that is different from reality. In addition, education on how to use fashion items and consumption attitudes in education related to clothing life will be required.

The purpose of this paper is to examine the change in perception of 3D virtual fashion before and after COVID-19 using big data analysis. The data collection period is from January 1, 2017, before the outbreak of COVID-19, to October 30, 2022, after the outbreak. Big data was collected for key words related to 3D virtual fashion extracted from social media such as Naver, Daum, Google, and YouTube using Textom. After the collected words were refined, word cloud, word frequency, connection centrality, network visualization, and CONCOR analysis were performed. As a result of extracting and analyzing 32,461 words with 3D virtual fashion as a keyword, the frequency and centrality of fashion, virtual, and technology appeared the highest, and the frequency of appearance of digital, design, clothing, utilization, and manufacturing was also high. Through this, it was found that 3D virtual fashion is being used throughout the industry along with the development of technology. In particular, the key words that stand out the most after COVID-19 are metaverse and 3D education, which are in high demand in the fashion industry.

4차 산업혁명과 메타버스와 같이 빠르게 변화하는 정보화 시대에서 디지털 사각지대에 놓인 '디지털 소외 계층'들이 존재하고 있다. 특히 고령자 같은 경우엔 빠르게 변화된 사회 속에서 보장받아야 할 디지털 교육을 받지 못하여 이제는 당연하게 누려야 할 편리함까지 놓치고 있다. 본 논문에서는 이런 문제들을 해결하기 위한 효과적인 디지털 교육 방안으로 '놀이'와 '게임' 그리고 '컴퓨터'를 융합시킨 'e스포츠'를 통해 디지털 치료제로서 제안하고자 한다. 이는 단순한 '교육'이 아닌 새로운 실버 콘텐츠로 접근하여 노인들의 또 다른 문화로 개척하며 디지털 소외 문제를 해결하는 것과 동시에 고령자들에게 'e스포츠'의 발전과 인식개선에도 기대해 본다.

기존의 안전교육 교수방법은 강의 방식으로 전달하고 있어 근로자의 참여를 이끌어내는데 한계점이 있으며, 불안전한 행동에 의한 안전사고를 예방하기 위해서는 스마트 체험식 안전교육으로 패러다임을 전환할 필요성이 있다. [연구배경/목적]:스마트 체험식 안전교육은 건설현장에서 근로자들이 보다 더 빠르게 위험을 인지하고 여기에 맞는 안전작업 이행과 위험발생 시 응급대처 능력 등을 향상시키므로 사전사후 학습전이의 효과성을 검정할 수 있다. 이러한 관점에서 안전사고를 예방하기 위한 본 연구는 안전교육의 체험학습방법과 참여방법, 교육콘텐츠 접근방법을 통하여 근로자의 안전행동 유도와 불안전행동 감소에 미치는 영향검증이 목적이다. [연구방향/범위]:실제 건설현장과 동일하게 작업환경을 구성해 놓은 스마트 체험식 안전교육시설에서 추락체험, 낙하물체험, 장비협착체험, 화재, 감전재해 등의 실제 사고를 체험해 볼 수 있도록 만들어진 체험학습 방법과 가상(VR, AR, 메타버스)공간에서 간접경험 할 수 있는 참여방법을 다룰 것이다. 그리고 안전체험교육 사전사후의 분석을 통하여 안전 학습전이 성과를 분석한다. [연구 분석방법]:연구의 주요 변인으로는 Human-Error, 안전행동요인, 불안전행동요인, 위험감수성, 조직특성, 조직의 안전문화, 조직의 역량, 안전교육특성, 교육콘텐츠 변화가 사전사후 분석을 통하여 현장 작업 시 안전 학습전이의 효과성을 검정하였다.

This study investigates the effectiveness of foreign language learning through diverse treatments in virtual settings, particularly by differentiating virtual environments with three textual enhancement techniques. A 2 × 3 mixed-factorial design was used, treating virtual environments as within-subject factors and textual enhancement techniques as between-subject factors. Participants experienced two videos, each in different virtual learning environments with one of the random textual enhancement techniques. The results showed that the interaction between different virtual environments and textual enhancement techniques had a statistically significant impact on presence among groups. In examining main effects of virtual environments, significant differences were observed in flow and attitude toward pre-post learning. Also, main effects of textual enhancements notably influenced flow, intention to use, learning satisfaction, and learning confidence. This study highlights the potential of Metaverse in foreign language learning, suggesting that learner experiences and effects vary with different virtual environments.

실사 영상 기반의 메타버스 환경을 구축하기 위한 다수의 카메라를 통한 영상 취득 및 부호화, 전송 기술이 활발히 연구되고 있고, 이를 위해 영상 압축 표준화 단체인 moving picture experts group (MPEG) 에서는 MPEG immersive video (MIV) 표준을 개발하였다. 하지만, 현재 널리 사용되는 가상 현실 영상을 스트리밍 가능한 장비의 연산 능력으로는 MIV 기반 몰입형 영상을 스트리밍 시 복호기 동기화 문제가 발생할 수 있다. 따라서 본 논문은 저사양 및 고사양 장비에서 적응적으로 복호기 개수를 조절 가능한 geometry packing 기법을 MIV 의 참조 소프트웨어인 test model for immersive video (TMIV)에서 구현한다. 제안하는 패킹 기법은 지오메트리 영상을 패킹하여 텍스쳐 영상과 같은 높이를 가지도록 한 후 각각 단일 서브픽쳐 (subpicture) 로 부호화한다. 이후 부호화된 서브픽쳐들에 적응적으로 비트스트림 병합이 적용되어 장비의 복호기 사양에 대응한다.

Interest in the metaverse is increasing as learners participate in learning with presence, improving learning motivation, and interaction. Currently, the use of metaverse in medical education remains in a test-phase of introduction within some companies, while some medical school professors are beginning to utilize it. Therefore, it is difficult to ascertain whether the metaverse has educational potential when used in medical education. This exploratory study investigates the possibility of the educational use of the metaverse. Both the educational usefulness and the examples of its educational usage in domestic and foreign medical schools are explored. As the metaverse is expected to be introduced and utilized more actively in the future, some of its advantages and limitations in medical education have been identified. In light of the vast potential of the metaverse in medical education, the method of educating and preparing medical students should be developed by preparing a new educational foundation.

Purpose This study aims to identify user experience factors that can enhance both metaverse utilization and satisfaction based on the honeycomb model. For this we presented two research questions: first, what are the experience factors of metaverse users? Second, do metaverse user experience factors impact satisfaction? Design/methodology/approach To address these questions, a mixed-methodology approach is employed, including text mining techniques to analyze online reviews and quantitative econometric analysis to reveal the relationship between user experience factors and satisfaction. A total of 69,880 reviews and ratings data were collected. Findings The analysis revealed eight metaverse user experience factors: entertainment, operability, virtual reality, immersion, economic activity, visual performance, avatar, and sociality, all of which were found to have a positive impact on user satisfaction.

Recently, content using VR technology in various fields is gradually increasing, and the technology is also rapidly spreading. Against this background, public libraries also need to provide services using VR technology according to the flow of the times. Therefore, this study drew application points through the investigation and analysis of domestic and foreign public libraries where VR programs are underway. And based on this, a final proposal is prepared after planning and reviewing VR-based educational and cultural programs in public libraries. VR-based educational and cultural programs introduced can be used as basic data for planning VR-based cultural programs in public library.
