코로나 19의 확산으로 인해 온·오프라인의 경계가 희미해짐과 동시에 비대면 형태 서비스가 확산되고 있으며, 교육 분야에서도 비대면 화상 강의와 원격수업의 적용이 일상화되고 있다. 기존의 비대면 화상 강의 시스템의 경우, 피교육자 신원확인 미흡에 따른 비인가자 접근 및 교육 방해 행위가 발생하였고, 교육내용 및 보고서 등 교육자와 피교육자 간 송·수신 내용 노출의 위험성이 있으며, 대량의 트래픽 유발에 따른 수업 방해가 가능하여 보안상의 대책이 요구된다. 본 논문에서는 기존의 비대면 형태의 피교육자 신원확인 미흡에 따른 비인가 접근 및 교육 방해 행위와 교육자와 피교육자 사이의 송·수신 내용의 위험성을 해결하고, 대량의 트래픽 유발에 따른 수업 방해에 대한 보안대책으로 블록체인 기반 DID 비대면 실습교육 플랫폼 설계를 제안한다.

By 'National GIS Plan', various strategies and programs have been carried out for the professional training in the fields of geospatial information. The e-learning can make it possible to develop and manage the adaptable curriculums, to maximize the effect of the practical exercises, and to establish the cooperative systems with the industries. In this study, curriculums of the geospatial fields were developed and suggested for the cyber universities. These curriculums were divided into three stages, fundamentals, applications, and advances, and into three tracks, system development and construction, mapping and geospatial data construction, and practice and application, based on the current demands in geospatial industries. Owing to be the modularized structure, proposed curriculums would be easily adapted and updated to the change of the new demands.

Because telemedicine is also the medical care, it is limited by law to allow medical personnel only physician because there would cause a risk to health and hygiene. Since the work dealing with the life and honor the human body involving a small mistake, it may be difficult to recover the damages can be recovered even if the telemedicine. Therefore, systematically it is to allow remote medical care only proven national healthcare only clinical practice starting with basic medical medicine, and received training as a systematic study of the body and life of humans. The patient information could get far away in the distance to provide medical information and professional advice to the remote system, even if you can not be reached due to several issues such as the number of differences that occur in time. We Mentioned various opinions on regulatory issues and information gathered for the development of the medical industry in this respect.

Recently there have been many Internet-based studies to provide personal users an efficient educational tool making use of multimedia data. The typical examples are remote education and virtual university where many educational trials on theory-based contents have been performed more frequently than those on experiment-based contents for engineering area. This paper describes about a base system implemented as an example of Internet-based experiment-oriented educations to establish cyber engineering laboratories for mechanics, electronics and chemistry. For the first time as a model of cyber engineering laboratories we herein Introduce in detail a server-and-client-based simulative method in which the result may be displayed on computer monitor of client PC while a simulator program is executed on the server. Secondly we introduce an interactive method in which the user of client PC may not only communicate directly with experiment server after initial connection with management server but also he can confirm the status of experiment being performed by way of video as well as experimental result.

The purpose of this study is a method to discover problems and improve them by analyzing the status of software education of A primary school conducted by online class. The coronavirus infection-19(COVID-19) pandemic, which began in early 2020, has continued to delay the start of the new semester. Finally, on April 9, 2020, the first semester began with online class. While progressing non-face to face online class, most students said they had difficulties. Students solved difficulties in class with Internet searches or program hints, not teachers. In the post-class self-evaluation, most students answered that there was no increase in coding skills. To solve this problem, the school rents additional smart devices to student. schools should have real-time interactive classes. After covid 19, online class became a paradigm for classes. Therefore, software education will also require research and development of curriculum and teaching learning methods suitable for online classes.

Fashion design education essentially requires not only a theoretical but also a practical process in which feedback comes through personal interactions between an instructor and a student. But the existing WBI system exemplifies its limitations by applying only a one-way Distance Education methodology that limit interactions based only on the theoretical texts. This study affirms that distance learning system is possible for the applied component of the fashion design curriculum as long as the specific needs of the particular program is taken into consideration and systematically applied. So it designed and applied an original web-based distance educational system specifically incorporating the needs of the fashion design curriculum Thus the results show that the enhanced distance education system is a tool that could be effectively utilized with the same degree of success as the traditional classroom as long as the traditional teaching component of direct interaction necessary to the fashion design program is incorporated.

Purpose: Due to the coronavirus infection-19 (COVID) pendemics, all educational institutions were required to provide full non-face-to-face real-time education, and fire officials were required to provide fire-fighting education by applying non-face-to-face education. In this difficult situation, the National Fire Service Academy tries to find the direction of the non-face-to-face real-time education and suggest ways to improve it through a survey of the status of non-face-to-face real-time education conducted by the NFSA to fire officials. Method: A survey was conducted on fire officials under the theme of "Consciousness Survey for Improving the Quality and Specialization of Non-face-to-face Real-Time Remote Education" and an in-depth analysis was conducted based on the results. Result & Conclusion: First, professors or educational operators shall actively utilize remote education programs suitable for educational characteristics by utilizing various programs. Second, a dedicated notebook for non-face-to-face training should be provided to provide an educational environment where all learners can participate in the training without difficulty. Third, in the case of education and training that requires the use of equipment due to the nature of fire officials' education and training, it is necessary to consider it as a non-face-to-face training place by arranging educational equipment at each fire station. Fourth, it is hard to expect a satisfactory educational effect to cope with practical education with theoretical education. Therefore, facilities and programs that enable non-face-to-face real-time hands-on training should be developed. It is worth considering the proper combination of face-to-face education while maintaining the social distance as much as possible until such non-face-to-face training is possible. Fifth, non-face-to-face education is considered to have high eye fatigue due to the light and electromagnetic waves of the computer screen, and as time goes by, the concentration level decreases. Therefore, it is necessary to form an education time to reduce the eye fatigue of learners and increase concentration through proper class and rest time. Finally, professors should operate a learner participation-oriented education that allows professors and learners to interact rather than one-sided knowledge transfer education. In addition, technical problems of non-face-to-face remote education should be thoroughly prepared through preliminary system checks to ensure that education is not disrupted.

In this paper, a cloud computing platform is designed and implemented based on an open source cloud platform, OpenNebula, and Xen hypervisor on each node for efficient computer lab system. For the purpose of convenient management, a web-based user interface has been developed for the cloud virtualization system. Once individual virtual machine is allocated to a user based upon class schedule, each user can access the virtual machine remotely and use appropriate operating system and application programs. The developed system can reduce computer lab upgrade cost, management cost, and administration time considerably.
