As COVID-19 spread, non-face-to-face activities were required, and the use of service robots is gradually increasing. This paper analyzed the relationship between the increasing trend of service robots before and after COVID-19 through keyword search containing the keyword 'service robot AND non-face-to-face' over the past three years (2018.10-20219) using BigKines, a news big data analysis system. As a result, there were 0 cases in the first period (2018.10~2019.9), 52 cases in the second period (2019.10~2020.9) and 112 cases in the third period (2020.10~2021.9), an increase of 115% compared to the second period. The keywords commonly mentioned in the analysis of related words in the second and third periods were COVID-19, AI, the Ministry of Trade, Industry, and Energy, and LG Electronics, and the weight of COVID-19 was the largest, confirming that the analysis keyword. Due to the spread of Corona 19, non-face-to-face is required, and with the development of information and communication technology, the field of application of service robots is rapidly increasing. Accordingly, for the commercialization of service robots that will lead the non-face-to-face economy, there is an urgent need to nurture human resources that require standardization and expertise in safety and performance fields.

This study analyzed the factors influencing the satisfaction of school students in Covid-19. The subjects of the study were surveyed in all 5th-6th grade of elementary school students, 1st-3rd grade of middle school, and 1st and 2nd grade of high school students in G metropolitan city. A total of 13,672 students participated in the survey, of which 13,613 were used for final data analysis. A hierarchical regression analysis of factors affecting students' life satisfaction showed that 22.2% of school life factors, 4.7% of home life factors, and 10.7% of daily stressors. The most influential factor in Covid-19 was home life satisfaction. Next was appearance stress for elementary school students and academic stress for middle and high school students. This can be seen as a result of Covid-19, which increased non-face-to-face classes and increased time for students to spend at home, which led to a greater impact on students' satisfaction in life. Nevertheless, middle and high school students can still see that academic stress has a significant impact on life satisfaction. Through this, it is necessary to support students to facilitate relationships, communication, studies, and leisure at home in the context of Corona 19. Especially, various educational policies must be accompanied so that the educational gap due to non-face-to-face classes does not deepen depending on the family environment.

This study deals with keywords from social media on domestic portal sites related to COVID-19, which is spreading widely. The data were collected between January 20 and August 15, 2020, and were divided into three stages. The precursor period is before COVID-19 started spreading widely between January 20 and February 17, the serious period denotes the spread in Daegu between February 18 and April 20, and the stable period is the decrease in numbers of confirmed infections up to August 15. The top 50 words were extracted and clustered based on TF-IDF. As a result of the analysis, the precursor period keywords corresponded to congestion of the Situation. The frequent keywords in the serious period were Nation and Infection Route, along with instability surrounding the Treatment of COVID-19. The most common keywords in all periods were infection, mask, person, occurrence, confirmation, and information. People's emotions are becoming more positive as time goes by. Cafes and blogs share text containing writers' thoughts and subjectivity via the internet, so they are the main information-sharing spaces in the non-face-to-face era caused by COVID-19. However, since selectivity and randomness in information delivery exists, a critical view of the information produced on social media is necessary.

We have changed a lot in our lives because of a disease called Covid-19.One of the biggest changes is to check the "disaster notification character" service spent in the country every time it is sent in real time. By the way, we cannot accept the characters of other regional disasters other than the area where we live. After visiting other areas, when we returned to the area where we relocated, we experienced difficulty in confirming the flow lines because we could not receive the characters of the flow lines of the corona confirmed persons in the visited areas separately. And if you use the broadcast-type broadcast service, you will not receive unnecessary copper wire information, and you will be able to obtain the characters of the disaster only where we visited. We try to provide app services to provide the public with more accurate and reliable information.

The purpose of this study is to examine how college students' stress coping in the post-corona era affect leisure constraint negotiations. To achieve the purpose of this study, from January 25th to February 19th, 2021, 247 copies were used for this study, excluding 13 questionnaires from Jeonbuk, Jeonnam, and Busan. For data analysis, descriptive statistics, confirmatory factor analysis, ANOVA and hierarchical regression analysis were performed using SPSS 21.0 and AMOS 18.0. As a result, there was a difference in leisure constraint negotiations according to changes in the types of leisure before and after COVID-19. According to the stress coping method of college students, it appears that it has a positive effect on the part of leisure constraint negotiations, so it is necessary to consider a detailed approach to the coping plan. In particular, it was confirmed that the active stress coping method(Active problem solving, Social support seeking) had a positive effect on the leisure constraint negotiations. Therefore, future research will require efforts to verify their relationship with various approaches to leisure constraints, leisure constraints negotiations, and stress and stress response strategies with COVID-19.

This study examines the social discourse on the characteristics of the learning community in the untact era, and discusses the directions that learning communities for children could explore and consider in the pandemic situation and beyond. For this purpose, big data for one year, from January 20, 2020 to January 20, 2021, were collected through internet portal sites (includingincluding Google News, Daum, Naver and other News surfaces), using two keywords "untact" and "learning community", and analyzed by employing a word frequency and network analysis method. The analysis results show that several important terms, such as 'village education community', 'operation', 'activity', 'corona 19', 'support', and 'online' are closely related to the learning community in the untact era. The findings from this study also have implications for developing the learning community as an alternative model to fill the existing gaps in public care and education for children during the prolonged pandemic and afterwards. In conclusion, the study findings highlight that it is meaningful to identify key terms and concepts through word frequency analysis in order to examine social trends and issues related to the learning community.

Amid global pandemic of covid-19, Korean government's response has drawn wide attention among social scientists as well as medical studies. The role of Korean state and civil society has attracted particular attention among others. Yet, this paper criticizes extant studies on Korean case which focus on the extensive intervention of the strong state and subjective attitude of Korean citizens in coping with covid-19. The concept of the strong state lacks social scientific specification and subjective citizens do not match with Korean realities. This article argues that Korean state's capacity in collecting and mobilizing digital data may offer better understanding for the successful responses to the pandemic. First, Korean state is the ultimate coordinator in collecting, analyzing and applying big data about the expansion of covid-19 with its huge network of dataveillance. Also, such role has been largely based upon relevant legal framework and well prepared manuals and cooperation with civic actors and companies. In other words, Korean digital dataveillance had demonstrated its transparency and cooperative governance. Second, such dataveillance capacity has deep roots in the long-term development of Korean state's big data management. Korean state has evolved about thirty years while enhancing digital data network within governments, companies and private sectors. Third, the relationship between Korean state's dataveillance and civil society can be characterized as a state centered push model. This model demonstrates highly effective governmental responses to covid-19 crisis but fall short of building social consensus in balancing individual freedom, human rights and effective containment policies. It means communitarian solidarity among citizens has not been a major factor in Korea's successful response yet.

The World Health Organisation(WHO), paying attention to the spread and fatality of the coronavirus(COVID-19), which first occurred in Wuhan, China, declared a global emergency. Although many countries implement strict measures to slow down the spread, WHO officially declared a pandemic. COVID-19 has sparked fears of an impending economic crisis and recession. Due to the economic crisis caused by social distancing, self-isolation and travel restrictions, the collapse of the world economic system centered on free trade and the decline of globalization are mentioned. Political leadership that has not responded properly to the pandemic is challenged, and nearly all of society is rapidly changing to a non-contact and immobile culture. COVID-19 has seriously affected all levels of the education system, from preschool to tertiary education. The so-called old concept of deschooling is realizing in the field of education through digital media paradoxically. Church education is facing a serious crisis as well. Churches are seeking now a new normal that includes theological reflection on the pandemic, online worship, education, and non-face-to-face ministry to overcome the worst unexpected crisis. In the post-corona era, church education must actively seek alternatives in response to rapidly changing surrounding conditions and reconstruct educational philosophy(theology) that focuses on Christian values. In addition, it is necessary to start operating a mobile(or online) church school that combines offline and online. It is necessary to introduce 'Blended Learning' method that combines non-face-to-face and face-to-face learning, and by combining church school and homeschooling, churches and families need to share the responsibility of education in faith.
