With Covid-19, the era of Untact has arrived. Online is bound to develop because face-to-face has become difficult among the threats of the Corona virus. Even in this era, even worship services to God have been offered online. Teenagers, the generation most accustomed to online, seem to easily adapt to online worship. Online youth worship is expected to continue even in the post-corona era. If so, the theological reflection on whether online youth worship is possible is necessary. Through theological reflection, we need to secure theological justification for online youth worship, and strive to make it a better and more accurate online worship service. Online worship tailored to the eye level of youth and online worship that meets the spiritual needs of youth should be planned, prepared, and implemented. This paper presented the theological justification for online youth worship by looking at the definition of worship, elements of worship, places of worship, and history of worship. In addition, while examining the characteristics of adolescence, it suggested why online youth worship is important and necessary. Then, in order to plan online youth worship that is more advanced and more accurate than the online worship currently being conducted in each church, the reality of online youth worship was presented by examining the purposes, contents, and methods of online youth worship.

This study aims to suggest the sustainable services for academic library in the New Normal Age, analyzing the online services during the COVID-19 pandemic. For this purpose, this study examined the operation condition of academic libraries' services during the COVID-19, analyzing the untact and online services of 63 libraries of universities which have more than 10,000 students. And this research classified the online services into three types, which are 'collection', 'facilities', 'programs' and examined the library homepage and development plans of academic libraries. This study also looked into the services of Korean public libraries and foreign libraries to suggest the sustainable services for academic library. As a result, this study suggests 'providing online materials for course reserves', 'expansion of research and study curation services to invigorate the use of library materials', 'introducing the smart library system and renovation of library facility and space services', 'planning of online programs through expansion of interaction with users'.

In the era of the 4th Industrial Revolution, the use of information based on AI APIs has a great influence on industry and life. In particular, the use of artificial intelligence data in the medical field will have many changes and effects on society. This paper is to study the necessary components to implement the "Cognitive Health Advisor model (CHA model)" and to implement the "CHA model using chatbot" based on this. It uses the open Cognitive chatbot to analyze and analyze the health status of users changing in their daily lives. The user's health information analyzed by the biometric sensor and chatbot consultation delivers the information to the user through the chatbot. And it implements a cognitive health advisor model that provides educational information for users' health promotion. Through this implementation, it intends to confirm the possibility of future use and to suggest research directions.

This study explores the potential of using a library chatbot to improve the non-face-to-face digital reference services for academic library users by designing and implementing a library chatbot. Through data analysis, user needs and library services were analyzed, and a scenario was designed by selecting an appropriate development method. For user-friendly interaction, the personality of the chatbot and user interface was designed to evaluate its usability. In addition, the accuracy was verified through the response accuracy evaluation and performance evaluation of the chatbot, and the effectiveness of the chatbot was evaluated through a user satisfaction survey. In order to manage the operation and maintain service quality, the chatbot is improved by monitoring user-chatbot conversations and reflecting user feedback. Based on these findings, recommendations for designing and implementing a library chatbot were made to help improve library reference services.

The prolonged untact era, which has continued since the end of 2019, further accelerated the spread of distribution platforms that provide cultural contents in digital form. Digital content distribution platforms are fiercely competing in the market as the central axis of cultural content planning, production and distribution. In this study, we apply the open innovation theory as a competitive element of digital content distribution platforms to assess whether competitiveness can be secured in terms of multilingualization of content.

최근 COVID-19 때문에 교육 및 모임 등 다양한 환경을 비대면으로 진행하고 있다. 이에 따라 메타버스 개념이 새로운 이슈로 주목받고 있다. 본 작품은 메타버스, 즉 3차원 가상공간의 새로운 세계에서 사용자를 대신하여 참여시킬 수 있는 아바타를 제작해 본다. 메타버스를 활용한 사용자의 움직임을 인식하는 3D 아바타는 코로나 사태로 인한 언택트 시대에 매우 유용하게 활용될 수 있을 것이다. 본 논문에서는 사용자가 각종 비대면 미팅에 자신의 아바타를 만들어 참여할 수 있도록 그 아바타를 움직임과 함께 구현하는 과정을 설명한다. 먼저, Kinect를 통해 사용자의 움직임을 받아 유니티를 연동시켜 불러온다. 다음으로 블렌더를 통해 사용자가 원하는 아바타를 제작하고 유니티 환경에서 사용자의 움직임을 실시간으로 반영하는 아바타를 나타낸다. 사용자는 자신의 행동을 그대로 반영시켜주는 3D 아바타를 가상현실 속 화면을 통해 확인할 수 있다.

최근 언택트 시대에 프리랜서 시장이 활성화되면서 재능거래 플랫폼이 빠르게 성장하고 있다. 이러한 재능거래 플랫폼은 판매 금액의 일정 부분을 중개 수수료로 책정하여 수익을 올리는데, 서버-클라이언트 모델 기반의 서비스를 제공하기 때문에 서버 운영비용이 발생하여 수수료가 높다는 단점이 있다. 본 논문은 분산저장파일시스템(IPFS)을 활용한 이더리움 플랫폼 기반 분산앱(dApp) 시스템에 대한 것으로, 거래 정보 같은 가벼운 데이터는 블록에 올리고 블록체인에 올릴 수 없는 대용량 데이터는 IPFS에 분산 저장 후 파일 주솟값인 CID 값을 블록체인에 올려 서버 및 데이터베이스 운영비용을 절감하는 방법을 제안한다.

Due to a long-term pandemic of COVID-19 since 2019, our society finally goes into 'un-tact (non-contact) era' in earnest by increasing an importance of non-contacted activities which are able to live without contacts among people. Un-tact era has influenced to generate a huge structural change with digitalization in our daily life as well as industrial society based on digital twin as an essential technology. As a technology representing real world in virtual digital world by integrating various technologies applied to 4^th industrial revolution, digital twin leads an innovation in industrial society with diverse industrial processes. But this technique isn't actively used across all industries due to structural limitations and environmental restrictions of digital twin. Especially, the field of construction and facility is necessary to use digital twin because it requires periodic managements of buildings in daily life and is directly connected with casualties in cases of disaster. But issues faced in reality are acting as an obstacle for applying digital twin. Therefore, this study suggests the necessity applying digital twin in facility safety response based on these issues and emphasizes active applications of digital twin by describing the expected effects being created. Furthermore, it connects to create demands of digital twin by overcoming current issues and suggesting high sustainable development.

Recently, with the development of virtual and augmented reality technology, metaverse is emerging as a new paradigm that will lead the next-generation internet era, and social and economic activities are spreading around the game, entertainment, music, and content industries. Moreover, as non-face-to-face conversion accelerated after the outbreak of COVID-19, lifestyles and industrial sites are becoming untact and further rapidly becoming a metaverse. In particular, the application of metaverse to the education field is attracting attention because realistic classes using real-time voice conversations using avatars, 3D objects, and 360-degree images can increase immersion and overcome the limitations of distance education. This study examines the concept of metaverse and examines that education using metaverse can be an alternative that can increase the efficiency of education in the non-face-to-face era. In particular, it shows that it is effective in language education and suggests an actual metaverse-based Korea language education program.
