Recently, for the preservation and transmission of cultural heritage, various researches and content development based on technologies such as virtual reality, augmented reality, and extended reality, which are the core technologies of the 4th industrial revolution era, are being conducted. Intangible cultural heritage is variable, unlike tangible cultural heritage, so it changes greatly depending on time and space, and as a result, it is in danger of being discontinued due to the aging and death of the inheritors. In this study, the current status and cases of related realistic content production were collected and analyzed, focusing on statistical data, intangible cultural heritage training centers through search portals, and platform cases. As a result of the analysis, it was found that overall, there were very few cases of use in content and transfer education using intangible cultural heritage. Through this study, we will consider ways to revitalize the effective transfer education of intangible cultural heritage that is on the verge of being cut off from transmission.

The virtual reality technology is currently used classifying functional types such as the observation operation type, the experimental activity type, the learning information type, the field problem-solving type, and other different types, based on the media's characteristics implementing 3D form of multi-sensory information. Using Virtual Reality, the restoration of the 'Doksu Palace' has been grafted onto J. Keller's ARCS model, suggesting a field restoration concept that reenacts the lives of the people that had been in the field with the cultural heritage and history based on a scenario based scene direction. This paper also summarizes 3 different types of implementation of the field restoration assorting multi-scene direction. Certain limitations exist, due to the fact that a completed prototype hasn't been suggested and that a detailed notion of the housing and 3D audio connection has been omitted.

Current]y, the lack of equipments for the medical practice and education made it impossible for the people in medical institution to carry out suitable experiments for observing human bodies. In this paper, the authors embodied three dimensional images and moving pictures for the human skeletal structure, digestive organs and their processes over the internet framework. The three dimensional images and moving picture made it possible for the general people as well as the specialists to observe and obtain informations with regard to the human body. Especially, the authors realized a framework for visualizing the human bodies in three dimensional images, via which a detailed and realistic architecture for the human body and its organs can be obtained. The system developed in this Paper can be used in the practice and education of the people engaged in medical fields.

Purpose: This study was conducted to confirm the usability of virtual reality-based anatomy education programs for nursing college students and to identify factors that affect their usability. Methods: Data were collected from 143 nursing college students in Gyeonggi-do using a structured questionnaire from May to June 2022. The data analysis was analyzed using real numbers, percentages, means and standard deviation, ANOVA, Scheff's test, Pearson's correlation, and multiple regression using the SPSS/WIN 23.0 program. Results: The subject's usability was 4.26 points (out of 5). The variable that has the greatest influence on the usability of virtual reality-based anatomy education programs is perceived innovation (β=.370, p<.001), followed by perceived pleasure (β=.295, p=.001), perceived ease (β=.253, p<.001), smartphone usage time per day (β=.102, p=.031). These variables explained 70.6% of the usability of virtual reality-based anatomy education programs. Conclusion: The results of this study can be utilized as basic data for a virtual reality-based anatomy education program that will be developed and applied to nursing students in the future.

With the rapid development of digital technology and the growing trend to integrate it into the medical field, recent studies suggest language rehabilitation for people with aphasia using virtual reality (VR), augmented reality (AR) and mobile applications. This study conducted a scoping review to summarize the features of digital technology-based language rehabilitation for aphasia in the last four years (2018-2021) and draw implications for future research. A total of 20 papers met the selection criteria among the documents retrieved from the Web of Science, CINAHL, and RISS. This review demonstrates that digital technology could offer unique treatment content by gamification, individualization, and creating a realistic communication environment, and by utilizing them in various ways. Therefore, we expect digital technology-based language rehabilitation for aphasia could supplement the limitations of conventional language rehabilitation and provide a novel perspective on development of treatment content.

In this study, safety education contents for medical radiation workers were produced based on Mixed Reality(MR). Currently, safety training for radiation workers is based on theory. This is insufficient in terms of worker satisfaction and efficiency. To address this, we created ICT(Information and Communication Technologies)-based MR radiation worker safety education content. The expected effect of Mixed Reality worker safety education content is that education is possible without space and time constraints, realistic education is possible without on-site training, and interaction between images is possible through reality-based 3D images, enabling self-directed learning Is that. In addition, learning in a virtual space expressed through HMD(Head Mounted Display) is expected to make education more enjoyable and increase concentration, thereby increasing the efficiency of education. A quantitative evaluation was conducted by an accredited institution and a qualitative evaluation was performed on users, which received excellent evaluation. The MR safety education conducted in this study is expected to be of great help to the education of medical radiation workers, and is expected to develop into a new educational paradigm as online education in accordance with Corona 19 progresses.
