The purpose of this study is to identify the chaotic state of school education caused by COVID-19 and to seek the role of the principal in responding quickly to the national crisis. To solve this problem, 34 elementary school principals in Seoul, Busan, Daegu, Daejeon, and Jeju were surveyed with open questions through the first SNS on what leadership is needed to cope with COVID-19, and the second in-depth interview was conducted through phone calls. In the New Normal era, principal's leadership requires insightful and responsible leadership in supporting educational activities, class support, and problem prevention that can occur due to rapid response to crisis situations, rapid budgeting and input, and promotion of teacher-to-teacher communication, according to a survey. In crisis situations such as COVID-19, it is necessary to establish a role of principal for schools to cope stably and to establish an educational environment in which students learn in a safe environment. For this, national and educational policy support is needed.

Ecomuseum which appeared in France in 1968 and widely diffused over the world, is a new type of museum. The purpose of this museum is not to simply possess and exhibit the existing relics, but to discover the locational senses of a territory by in-situ conserving and interpreting its entire natural and cultural heritages, and to plan the participation of its population and the development of its local community. The significance of this museum can be found in the recovery of disappearing collective memories of a territory, the restoration of the cultural identity of its population and the revitalization of a underdeveloped area. As the majority of these museums are fragmented or open air museums, an 'web ecomuseum' which makes the remote offering of informations about whole dispersed heritages and their holistic interpretation possible by digitalizing, recording, conserving, interpreting and utilizing related heritages, is necessary. This paper considers the possibility of web ecomuseum and its constitution contents and methods through the case of Mountain Mudeung area. Especially, in relation to the latter, this paper suggests a plan which consists of selection of own local themes, construction of digital archives, design of web expositions and production of electronic cultural maps.

In a network environment, when a user requests a server's service, he/she must pass an examination of user authentication. Through this process, the server can determine if the user can use the provided services and the exact access rights of this user in these services. In these authentication schemes, the security of private information became an important issue. For this reason, many suggestions have been made in order to protect the privacy of users and smart cards have been widely used for authentication systems providing anonymity of users recently. An remote user authentication system using smart cards is a very practical solution to validate the eligibility of a user and provide secure communication. However, there are no studies in attribute-based authentication schemes using smart cards so far. In this paper, we propose a novel user authentication scheme using smart cards based on attributes. The major merits include : (1) the proposed scheme achieves the low-computation requirement for smart cards; (2) user only needs to register once and can use permitted various services according to attributes; (3) the proposed scheme guarantees perfect anonymity to remote server.

Purpose: The COVID-19 pandemic has changed how healthcare is delivered worldwide and has affected the environment of the healthcare. Physical therapy in traditional healthcare systems can be difficult in unusual circumstances, such as the COVID-19 pandemic. Tele-physical therapy, defined as "the delivery of the physical therapy at a distance using electronic information and telecommunication technologies," will be a solution for this healthcare crisis. Thus, in this study, we proposed a mobile application for tele-physical therapy. Methods: This study used the Chrome Browser version 83.0.4 based on the Windows 10 64Bit operating system to use the App Inventor. To operate the mobile application, we used the Samsung Galaxy Note 9. The design of the mobile application was based on the review of a system used in the physical therapy department. Results: The graphical user interface (GUI) of the mobile application was displayed on three screens: selecting a painful joint (1st screen of the GUI); selecting a painful movement of the joint (2nd screen of the GUI); a self-manual therapy method and movie (3rd screen of the GUI). The proposed mobile application showed the stable repeatability of the self-manual therapy movie. Conclusion: The results of this study demonstrated that the proposed mobile application using the App Inventor for android will be able to create easy to use and reliable tele-physical therapy.

The interest in online education has increased due to the spread of COVID-19. Especially, in the online environment, the importance of scaffolding, which refers to the help and support provided by instructors or peer learners, is being emphasized. This study aimed to review the antecedents of online scaffolding at the university of Korea through the method of systematic review. For this purpose, we collected 578 studies conducted from 2010 to 2021 and selected 7 studies according to the criteria of selection and exclusion. As a result, we found general features, types, and effects of online scaffolding at the university of Korea. Based on these results, we discussed suggestions and implications for a follow-up study. We hope many empirical kinds of research will be conducted about online scaffolding at the university.
