Due to COVID-19, which has thrown the whole world into chaos, it has become an era where many technologies and contents are made non-face-to-face. At the same time, the popularity of the metaverse service is also increasing day by day, and the virtual costume (avatar) industry, one of the sub-industries, is also growing. In this study, we designed and developed a system for creating virtual costumes to be uploaded to ZEPETO, a mobile metaverse service. Unlike the existing service that requires a program that operates in a PC environment, it can be produced only by shooting and simple operation through a mobile device. With the advantage of being able to process all tasks of this system in a mobile environment, small businesses and individual operators who are not familiar with external programs will be able to more easily access the 3D virtual clothing industry.

In an era where non-face-to-face meetings become common, eXtended Reality(XR) is rapidly developing and filling areas that are not satisfied in online meetings based on existing photos/video method. In particular, general users are also able to easily access and use HMD-type mixed reality devices. However, the basic operations applied in HMD-type in Mixed Reality(MR) with hands as the main input tool do not have a standardized system, and each manufacturer operates in a separate response to each other's hand movements. Therefore, this study considered that a systematic hand motion matching system considering the usability and efficiency of operations performed in mixed reality was necessary, and conducted a study to clarify this. First, the basic operation performed in the MR environment and its attributes were investigated, and at the same time, the structure of the hand and the attributes of the possible hand movements were identified. Based on the identified properties, it is intended to present a system that can intuitively and efficiently match basic operation properties in the MR environment with subtle operation properties according to the structure/context of the hand.

COVID-19 is also influencing the coffee industry. This will increase untact consumption, a new consumption trend. Consumption utilizing online channels and delivery service applications that represent untact consumption is becoming commonplace. The coffee industry is also increasingly using coffee shops with drive-through and smart ordering systems that can be ordered with minimal contact. While most of the untact services are preempted at franchise stores, many independent coffee shops still offer differentiated services by communicating directly with customers. However, along with the prolonged COVID-19 infection, coffee shops in the present era, which cannot be free from infectious diseases, have no choice but to worry about delivery services. Therefore, this study analyzed the factors that influence coffee delivery services. Research results due to the influence of COVID-19, regular delivery services have increased along with coffee delivery services. Regular delivery services will play a central role in coffee delivery services due to increased use of home cafes by consumers who want to enjoy coffee in various ways.

This study is places importance on health and safety in the era of untact, non-face-to-face care areas are increasing. To find out the fun factors and the effect of immersion on use satisfaction of health application users. Through the first factor analysis, we found the fun and immersion elements(joyful, interest, social intercourse) of users. Secondly, we looked at the impact of fun factors and immersion on satisfaction (viral intention, continuity). Finally, we looked at whether the user's characteristics affect satisfaction. The impact on fun factors and satisfaction was different depending on gender, which are characteristics of health application users. Both men and women showed significant results in oral tradition of pleasure, and in the case of women, elements of joy and psychological compensation were found to affect the continuation of use. It is thought that it is important to consider this in terms of marketing so that the elements of enjoyment among the fun factors of users through health application can continuously affect the continuation of use or oral tradition.

This study noted the recent impact of Coronavirus Disease-19 (Corona 19) on the environment surrounding the library, and investigated the libraries' response activities. In addition, related issues on news media and social media were detected based on text mining techniques to engage environmental changes surrounding the library. Key issues were derived from 1,852 news reports on the library related to the Corona 19 situation and 227,983 tweets related to the library during the Corona 19 epidemic. Through this, implications were derived: prolonged 'Untact' situations, increased e-book lending, improved expectations for online services and librarians, and re-conceptualized library space. In addition, the direction of future services was discussed by selecting representative examples of library services provided in the non-face-to-face (untact) situation and dividing them into books, services, and spaces.

It has been determined the 6 core competencies of our university students. Among them, it was judged that the student's convergence thinking ability and self-development ability were insufficient. To enforce the two insufficient abilities, an engineering-related major collage course was newly established in the form of an intensive coursework. The course was conducted as a shared curriculum between division/departments. For each of the first and second semesters in the 2020, 54 students from two completion groups (Department of Electrical and Electronic Control Engineering; 26, Optical Engineering; 28) were the subjects of the survey, the survey results of 20 common questions were comprehensively analyzed. As the result, more than 75% of the respondents were positive about free online learning at any time and place. And if additional interactive activities and team teaching method are reinforced during recorded audio and video contents learning material, It is confirmed that the attempted intensive course can maximize the learning effect.

Today, in the era of the 4th industrial revolution based on the paradigm of hyper-connectivity, super-intelligence, and superconvergence, the remote work environment is becoming central based on technologies such as mobile, cloud, and big data. This remote work environment has been accelerated by the demand for non-face-to-face due to COVID-19. Since the remote work environment can perform various tasks by accessing services and resources anytime and anywhere, it has increased work efficiency, but has caused a problem of incapacitating the traditional boundary-based network security model by making the internal and external boundaries ambiguous. In this paper, we propse a method to improve the limitations of the traditional boundary-oriented security strategy by building a security model centered on core components and their relationships based on the zero trust idea that all actions that occur in the network beyond the concept of the boundary are not trusted.

In the post-corona era, telemedicine is becoming more important. This is the case in which it is written, in terms of this study, and in relation to the relationship between the Koreans and the Korean government. In addition, the aim is to prepare effective measures and seek policy suggestions for expanding the introduction of domestic telemedicine in the future. Although Japan has insisted on the necessity of introducing telemedicine in the medical community, it has institutionalized it with a cautious attitude until the establishment of telemedicine. On the other hand, South Korea lacks clear provisions on medical fees for telemedicine and legal measures regarding the responsibility for medical malpractice. Therefore, a clear legal interpretation of the telemedicine subject is needed, and a strategic approach is prioritized, including guidelines and measures for the legal responsibilities and limitations of physicians and patients.
