  • This study empirically analyzed the effects of immersion and self-efficacy on the intention to continuously use realistic media. To this end, we used an extended technology acceptance model that includes not only the perceived ease of use and usefulness, but also the perceived joy as important factors. We collected data from 595 participants through an online questionnaire survey and tested the research model using a covariance-based SEM. As a result, we found that a user's immersion significantly increased perceived usefulness, ease of use, and joy of realistic media; and self-efficacy increased perceived usefulness and ease of use. Although the effect of perceived usefulness was relatively stronger than that of perceived joy, we found that the effect of perceived joy on the intention to use was also quite large. The effect of perceived ease of use on intention to use was found to be completely mediated by perceived usefulness and joy. In addition, the differences according to the types of media were tested by comparing two groups: augmented reality and virtual reality. The effects of perceived ease, usefulness, and joy on the intention to use were very similar regardless of the type of immersive media. However, it was found that self-efficacy increases usefulness only in augmented reality. Based on our findings, we have discussed the implications of our study, as well as the scope for future research.

  • 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.

  • Recently, the importance of CPR training for the layperson has been emphasized to improve the survival rate of out-of-hospital cardiac arrest patients. An accurate and realistic training strategy is required for the CPR training effect for laypersons. In this study, we develop an extended reality (XR) based CPR training system and evaluate its usability. The XR based CPR training system consisted of three applications. First, a 3D heart anatomy image registered to the manikin is transmitted to the smart glasses to guide the chest compression point. The second application provides visual and auditory information about the CPR process through smart glasses. At the same time, the smartwatch sends a vibration notification to guide the compression rate. The 'Add-on-kit' is a device that detects the depth and speed of chest compression via sensors installed on the manikin and sends immediate feedback to the smartphone. One hundred laypersons who participated in this study agreed that the XR based CPR training system has realism and effectiveness. XR based registration technology will contribute to improving the efficiency of CPR training by enhancing realism, immersion, and self-directed learning.

  • This study aimed to propose a method for collecting and applying media platform based materials at the National Library of Korea. Firstly, we analyzed the current status and limitations of data collection based on domestic media platforms, including the National Library of Korea. Secondly, a literature review method was used to investigate the current status and types of digital content based on media platforms. Thirdly, we identified the types of materials based on media platforms that are not currently included in the National Central Library's online material collection guidelines through the examination of cases from major overseas libraries. Fourthly, after reviewing technical and legal elements such as the definition of collection targets and scope for each new media, and collection methods, we established collection criteria. Fifthly, based on the research results, the policies proposed in this study are as follows: 1) there is a need to establish a clear legal basis for the collection of media platform based materials; 2) the development and presentation of collection guidelines for media platform based materials is necessary; 3) the development of collection tools and infrastructure for media platform based materials is required; 4) for the collection of media platform based materials, it is necessary to obtain permission for collection from targeted social media organizations, and to cooperate in linkage with organizations that produce and service extended reality content; 5) for the service activation of media platform based materials, it is necessary to improve accessibility for the usage activation of these materials, to enhance the content extensibility and ease of use of the e-deposit system including extended reality content, and to advance and construct spaces for reproducing extended reality content.

  • Initial imperfections, such as initial deflection or remaining stress, cause deterioration of buckling strength of structures. The Koiter imperfection sensitivity law has been extended to describe the mechanism of reduction for structures. The extension is twofold: (1) a number of imperfections are considered, and (2) the second order (minor) imperfections are implemented, in addition to the first order (major) imperfections considered in the Koiter law. Yet, in reality, the variation of external loads is dominant over that of imperfection. In this research, probabilistic evaluation of buckling loads against external loads subjected to probabilistic variation is conducted by extending the concept of imperfection sensitivity. A truss arch subjected to dead and live loads is considered as a numerical example. The mechanism of probabilistic variation of buckling strength of this arch is described by the proposed method, and its reliability is evaluated.

  • Recently, a wide range of next-generation's game consoles has been developed by many game makers. Particularly, active interaction between users and games is required more than ever before for giving gamers the fullest pleasure. In this work, an infrared image sensor based position recognition system which can be used for virtual game interface is proposed. Furthermore, two kinds of compensation algorithms and Extended Kalman Filter are utilized to enhance the performance of the proposed system. The proposed system can effectively generate the position of the gamer in the face of the coordinate distortion and noise. To verity the feasibilities of the proposed system, various experiments are carried out.

  • The purpose of this study is to capture how marriage migrant women, who are burdened with the luggage of the social, cultural, and historical 'past,' reconstruct their own 'experiences in reality' as subjective agents after their immigration into a new space. By applying a phenomenological method, this study analyzes the world of life in which marriage migrant women come to have experiences in the dimensions of bodilihood, spatiality, temporality, and relatedness. As a result of the analysis, marriage migrant women never think of their bodiliness as the subject of discrimination though they have some differences in skin colors and cultural aspects, and make efforts to overcome prejudices in reality withtheir pride of body. As for the spatiality, marriage migrant women attempts at a spatial turn in which they reconstruct a novel sociocultural space. With respect to the temporality, marriage migrant women recognize themselves not as passive subjects who only resent reality but as being prepared for future actively. As for the relatedness, marriage migrant women show life in which they pioneer their own areas on the basis of extended personal relations.
