The spread of COVID-19 has caused confusion in the education field as it has led to the implementation of untact classes without preparation. The purpose of study is to find ways to effectively design and operate untact classes for tax accounting department. The survey and FGI were conducted on professors and learners. As a result, video classes through lecture shooting and PPT-based video conversion were the most utilized. Students prefer these two types most, because they can learn repeatedly regardless of time and space. The improvement measures are as follows. For video classes that reflect various characteristics of the subject, supporting for equipment and human resources is needed, and for professors, teaching support for untact classes and education on equipment manipulation is needed. Continuous Quality Improvement for untact classes should be overhauled. In the future, in-depth research is needed to various majors, this will help find ways of untact classes suitable for the characteristics of the subjects.

The threat of COVID-19 pandemic put many universities in Korea to develop and implement various types of untact online classes. Online education has been recognized as one of the effective educational methods because of its ubiquitous and flexible educational environments. However quick move to online education caused by the sudden attack of the COVID-19 led to many problems such as faculty's burden and stress from the planning and designing suitable for online classes, technology system problems for both students and faculty and students' complaints of the low quality of education. The primary purpose of this study is to investigate the effects of learner, contents, and instructor factors on college student satisfaction with untact online classes during the first attack of COVID-19 pandemic. The data were collected from 605 undergraduate students of S women's university based in Seoul, who took the untact online classes in the spring semester 2020. The results of empirical analysis reveal that only contents factor are likely to predict learner satisfaction. These findings provide insights that the effective planning and designing classes are key to enhancing learner satisfaction with online education. This study suggests that instructors need various contents developed and educational strategies for students.

This study examined how the use of learning apps in Zoom-based classes affects learners' English achievement and assessed the efficiency of app use in Zoom-based English classes. The study utilized the English Central (EC) app to induce learners to actively participate in zoom-based classes. To assess the app's efficiency, two rounds of achievement tests and an open-ended questionnaire were administered. The two tests showed that Zoom-based EC app utilization classes positively affected learners' English achievement and the questionnaire revealed that the learners were highly satisfied with using the EC app in Zoom-based classes. The participants praised this approach for "complementing insufficient class content" and facilitating "immediate feedback" (on the EC app), "English practice," and "real-time communication and sharing of opinions" (on Zoom-based classes), describing it as "not boring" and "4 skill training in English." Instructors should strive to efficiently use such new teaching tools in the evolving environment of the untact era.

This study conducted and evaluated the PBL-based team activity classes in contact and untact learning. Appropriate subject (Engineering communication) was also selected and evaluation methods were improved. In the qualitative evaluation results, in contact learning, similar score ranges were formed for each task, and the variability of scores for each task was not large. In untact learning, the difference in scores for each task was rather large, and the variability of scores for each task was large, indicating a large difference between teams that performed well and teams that did not. In the quantitative evaluation, contact learning showed a little low grades, but untact learning showed relatively high grades, but there were limitations in showing the conclusion that the untact learning effect was very good. As a result of the survey, there were more positive responses to the degree of understanding of the class conducted online, the degree of help to improve competence, and the team activity. However, if untact learning continues, it was analyzed that it is necessary to prepare appropriate measures to enhance learning effects and efficiently conduct team activities.

In this study, we analyzed the application of flipped learning in the untact online classes, focusing on thr social and engineering subjects of universities. Due to the unprecedented situation of COVID-19, the professors and learners were unable to conduct the face-to-faceclasses, and the existing flipped learning classes were analyzed separately from the social and engineering subjects. In particular, the results of this study will provide the basic data on the direction of post-corona-era university classes in that it can increase the effectiveness of flipped learning if it is linked to the flexibility of the university's academic system such as intensive course.

Since the global spread of COVID-19, social distancing and untact service implementation have spread rapidly. With the transition to a non-face-to-face environment such as telework and remote classes, cyber security threats have increased, and a lot of cyber compromises have also occurred. In this study, cyber-attacks and response cases related to COVID-19 are summarized in four aspects: cyber fraud, cyber-attacks on companies related to COVID-19 and healthcare sector, cyber-attacks on untact services such as telework, and preparation of untact services security for post-covid 19. After the outbreak of the COVID-19 pandemic, related events such as vaccination information and payment of national disaster aid continued to be used as bait for smishing and phishing. In the aspect of cyber-attacks on companies related to COVID-19 and healthcare sector, we can see that the damage was rapidly increasing as state-supported hackers attack those companies to obtain research results related to the COVID-19, and hackers chose medical institutions as targets with an efficient ransomware attack approach by changing 'spray and pray' strategy to 'big-game hunting'. Companies using untact services such as telework are experiencing cyber breaches due to insufficient security settings, non-installation of security patches, and vulnerabilities in systems constituting untact services such as VPN. In response to these cyber incidents, as a case of cyber fraud countermeasures, security notices to preventing cyber fraud damage to the public was announced, and security guidelines and ransomware countermeasures were provided to organizations related to COVID-19 and medical institutions. In addition, for companies that use and provide untact services, security vulnerability finding and system development environment security inspection service were provided by Government funding programs. We also looked at the differences in the role of the government and the target of security notices between domestic and overseas response cases. Lastly, considering the development of untact services by industry in preparation for post-COVID-19, supply chain security, cloud security, development security, and IoT security were suggested as common security reinforcement measures.

In the case of long-term hospitalization for young patients, 'Hospital Schools' are operated to pursue school classes and to develop social and emotional abilities for them. However, face-to-face classes at hospital schools have been completely prohibited, and the untact or limited contact environment has been strengthened even for young patients due to the COVID-19 in recent years. Augmented Reality(AR) technology enables the development of experiential content with virtual environments, objects and characters similar to real life. The developed contents should revitalize the imagination of young patients living only in hospitals and allow them to experience, not only acquiring knowledge, but also improving interpersonal skills and sociality. This study is intended to provide diverse adventures and in-depth choice experiences to young patients who are struggling in an environment of untact and limited contact by creating experiential fairy tale contents using AR technology. In addition, long-term hospitalized children will be able to cultivate the will to overcome illness with positive emotions through the augmented reality experience fairy tale content studied and implemented in this study.
