The purpose of this study is to present measures to enhance non-face-to-face communication platform services by measuring the user experience elements of major videoconferencing platforms in the non-face-to-face era. As a method of research, the platform of Zoom and MS Teams was selected, and the factors affecting the user experience were evaluated in combination with task and Think Aloud, and seven Honeycomb models of Peter Mobil were reconstructed to be analyzed through surveys and in-depth interviews for each paragraph. Studies have shown that Zoom has high usability, usability, accessibility and searchability, and MS Teams have excellent attractiveness. Therefore, based on the results of this study, the guidelines for video conferencing platform services and the improvement of the interface were presented. Based on this study, we hope that the usability of videoconferencing will be improved, and that various related studies will proceed as follow-up studies.

In an acceleration of 'untact' society during the COVID-19 pandemic, video conferencing platforms have been provided to connect the isolated and to overcome the limit of having interpersonal relationships. While these services brought a great deal of benefits, they also increased the number of people who suffer from additional fatigue from video conferencing. This study, thus, aimed to identify the factors of using video conferencing services and further to examine the relationship between the factors and the users' overall fatigue. Through focus-group interviews and survey, four main factors of fatigue (restriction from untact communication, difficulty of use, background set-ups, discomfort from excessive attention) were identified. This study also found the positive relationships of restriction from untact communication and background set-ups on the users' overall fatigue. The results does not only provide implication on defining new fatigue factors from young generations but also help practitioners and service providers to improve the deficits of services that the real users currently experience.

Metaverse is at the center of heated debates in many areas recently. Coupled with real world, metaverse is extending its domain into social and cultural activities in addition to economic value creation as untact activities increase. Global companies are investing in R&D for metaverse. The reason is that metaverse is supposed to create new value by converging virtual and real worlds thanks to technology advancement such as AI, big data, 3D graphic, 5G, cloud computing, etc. Thus, innovative changes are expected in the economic, social and cultural areas. However, there are many problems to be solved yet for connecting virtual world and real one. Also, epoch-making development of products and services should be done for realistic experience and profit creation using virtual space in various industries beyond untact social activities against pandemic situation. The essence, present condition, development and its application areas of metaverse will be analyzed, and expected problems researched so that the strategy and methodology for securing global competitiveness will be addressed in coming metaverse era.

Edutech is a compound word of education and technology, and is an educational paradigm in the era of the 4th industrial revolution. This refers to next-generation education using information and communication technology (ICT) such as big data, artificial intelligence (AI), robots, and virtual reality (VR) of the 4th industrial revolution. e-Learning is being used as an online lecture for education in ICT, but edutech is attracting attention along with e-learning as the feeding of non-face-to-face education has rapidly increased due to COVID-19. Therefore, this paper summarizes the reviewed papers on the blockchain-based badge service platform, simulation-based collaborative e-Learning system, video English dictionary, and blockchain-based access control audit system.

The purpose of this study was to identify the convergence factors influencing learning satisfaction of nursing students in the COVID-19 pandemic after applying non-face-to-face mixed classes consisted of both real-time and non-real time distance educations. The participants were 109 nursing students who attended in a university and completed the self-report questionnaire. Data were analyzed using the SPSS 23.0 program. The results showed that the learning flow was 3.41, self-regulated learning ability was 3.75, and learning satisfaction was 3.98. Learning satisfaction showed a positive correlation with learning flow (r=.42, p<.001) and self-regulated learning ability (r=.75, p<.001). In addition, the factors influencing the learning satisfaction of the subjects of this study were self-regulated learning ability (𝛽=.662) followed by 60.6% (F=25.63, p<.001). Therefore, to enhance learning satisfaction of nursing students, it is necessary to increase their self-regulated learning abilities and to develop and apply training program considering the needs of the educational environment change in the post-COVID-19 era.

비대면 시대로 인한 화상 회의의 중요성이 높아졌다. 하지만 현재까지도 회의기록의 문서화 작업은 수작업으로 이루어지고 있어 시간과 인적자원이 많이 소모되고 있다. 본 논문은 기존 수작업으로 진행되는 회의 문서화 과정의 문제점을 개선하고자 한국어 키워드 추출을 활용한 인공지능 회의록 자동 생성 시스템을 제안한다. 회의 음성 파일을 기반으로 STT 기술을 활용한 회의 전문을 자동 생성하고 전문에 KR-WordRank 알고리즘을 적용해 키워드를 추출, Summary API를 사용하여 요약본을 생성한다. 최종 결과로 회의 전문과 키워드, 요약본이 담긴 PDF 형식의 회의록을 사용자에게 제공하여, 수기 회의록 작성 시 들이는 시간적, 인적 비용 절감을 돕는다.
