The purpose of this study was to survey and analyze the effects of job satisfaction and job stress on organizational commitment among radiological technologist working in primary, secondary and tertiary hospitals in Busan. As a result, the scores of job satisfaction and organizational effectiveness of the tertiary hospital were significantly higher (p<0.05). In the group with no turnover experience, the organizational commitment, job satisfaction, and organizational effectiveness scores were significantly higher (p<0.05, p<0.01). Job stress was not statistically significant between variables in the analysis of general characteristics. Hierarchical regression analysis showed that the radiological technologist organizational commitment had the highest impact on job satisfaction (β=0.703, p<0.001). Radiological technologist are important in the diagnosis and radiation therapy of diseases in hospital. Therefore, based on the results of this study, it will be helpful to analyze the relationship between job satisfaction, job stress and organizational commitment of radiological technologist, and to prepare a plan to increase their organizational commitment.

This paper investigates the relationship between R&D professionals' career plateau and organizational commitment in which career plateau's sub-dimensions consist of structural and job-content plateau. Further, it aims to examine the moderating effect of age and creative behavior of R&D professionals on the relationship between career plateau and organizational commitment. Empirical data were collected from 418 R&D professionals who work for Government sponsored research institutions. The results showed that the relationship between structural plateau and organizational commitment is differently related depending on age level. That is, the negative relationship between structural plateau and organizational commitment is stronger for junior R&D professionals. Furthermore, the relationship between job-content plateau and organizational commitment is negatively related, and differs in the strength depending on the creative behavior level of R&D professionals. For one with stronger characteristics of creative behavior, job-content plateau is more negatively related to organizational commitment. Based on the results, some implications are suggested on the career plateau issues of R&D professionals who work for government sponsored research institutions. Finally, it is discussed on the limitations of this study and further research directions.

Lately the VR (Virtual Reality) game genre is becoming increasingly more popular and it has been cementing its place in the market as its own independent game genre. The key advantage of VR is that it lowers the barrier between player and the virtual world, thus creating an immersive experience. The suggested method develops a game that allows the player to experience what it is like to be visually impaired using the unique characteristics of VR. A distinctive feature of this game is that the character is provided only a limited range of sight, which is created using silhouette outlines. This restrictive visual field is then grafted onto VR and the player can indirectly experience blindness in a highly immersive manner. The silhouette outline along with the particle system is created using Oculus Rift, a headset highly used in VR game development, and Unity 3D game engine. We will also explain in detail regarding the removal of borders between the objects.

In this study, we aim to design an action game that increases the user experience. In order to increase the immersion of the game, the characteristics of the game used by the user were analyzed, and the systemic and visual characteristics of the game were designed with reference to each characteristic. The proposed method uses Unity 3D to implement an interaction system between objects in the game and is designed in a way that allows users to immerse themselves in the game. To induce immersion through the visual elements of the game, 2D objects and players are placed in a 3D space, and a 2D dynamic light shader is added. It is composed of inter-combat rules and monster behavior pattern collision detection and event detection. The proposed method contained the user experience with the implementation thesis, and showed the game's possibility of leading the user's affordance.

The metaverse applies various technological means such as digital twin modeling, 3D rendering, and holographic imaging, which can provide an immersive tourism service experience. However, since the development of the metaverse is still in its infancy, there is relatively little research on digital tourism from the perspective of the metaverse. This research empirically studies the factors that promote the participation behavior of users on the metaverse platform for digital cultural tourism. Our results show that users' internal motivations for learning and entertainment and the functions provided by metaverse, which are sensory stimulation and social interaction lead to the intention to participate in cultural tourism on metaverse with the mediating effects of immersion experience and perceived pleasure.

Presence, flow, and arousal are interesting user experiences provided by video and people's demand for media which responds to personal interest is getting strong. This research compares video watching and game play by conducting a survey and measuring brain wave to find out the difference of those user experiences in the two media. As a result, all the three user experiences were proved to be significantly higher in game play than video watching. And those EEG frequencies which are known to be related to the state of flow were also measured higher scalp distribution of the game play group. Finally, presence, arousal, and EEG(${\alpha}$, ${\beta}$, ${\delta}$) were found to have influence on the flow state in game play. This research is intended to prove above relations by experiment and make a contribution to the theoretical and methodological improvement in the related area.

Objective : Tellegen Absorption Scale(TAS) is an instrument intended to assess hypnotizability and designed to sample absorbing and self-altering experiences, including dissociative experiences. The present study attempted to identify the internal structure of TAS. Methods : One hundred and thirty nine undergraduates completed the Korean version of Tellegen Absorption Scale(TAS-K). Cronbach's alpha was calculated and factor analyses were done. Results : An exploratory principal-components analysis yielded three factors accounting for 31.06% of variance. Factor 1 included dissociative(dissociation-like) experiences, factor 2 tapped imaginative involvements, and factor 3 had to do with perceptual sensitivity. Conclusion : TAS-K may include absorbing and self-altering experiences.

Realistic education using virtual reality compared to traditional learning can enhance students' understanding of knowledge through immersion and interaction. In previous studies, VR education is mainly focused on experiences, and it is difficult to find its applications for environmental education. Environmental issues are a global problem, and environmental education is essential for the future. In this research, we developed an immersive virtual reality-based environmental education simulation designed to help students recognize the importance of environmental education and participate in environmental-friendly actions. This simulation is based on the virtual ecosystem model, which maintains a casual relationship among environmental factors, spatio-temporal connection, and persistent state. Users intuitively recognize environmental problems and is motivated to solve the problem while experiencing the results of interaction related to environmental factors in virtual environment.

This study organizes an immersive content production pipeline using Meta Quest Pro as an asymmetric virtual environment where mixed reality(MR) and virtual reality(VR) users participate and interact together. Based on this, we compare and analyze the differences in presence and experience provided by the user's experience environment. The proposed production process is to build an integrated development environment using Meta XR All-in-One SDK based on the Unity 3D engine. This includes a real space analysis method using the Room Model function for organic and accurate interaction between MR users in the real world and VR users based on virtual scenes at fixed coordinates. Based on this, this study produces immersive table tennis content where MR and VR users participate together. Finally, we conduct survey experiments to compare and analyze the effects of differences in platform and participation methods on presence and experience using the produced content. As a result, this study confirmed that all users can feel a satisfactory presence and experience within an experience environment where real and virtual correspond.

This study investigates the relationships among learning motivation, learning immersion, and academic achievement in college-level nursing students who give non-face-to-face online lectures. The data for this study were collected using questionnaires given to 147 students attending four-year nursing colleges at two universities. For the data analysis method, descriptive statistics, t-test, ANOVA, the Scheffe test, Pearson's correlation analysis, and multiple regression analysis were used. As a result of the study, the average motivation was 101.29±12.18 points, learning commitment was 72.02±8.03 points, and academic achievement was 31.31±4.06 points. The relationships among learning motivation, learning commitment, and adaptation to college life showed significant positive correlations. In the results of multiple regression analysis, factors influencing the academic achievements of nursing students were found to be learning motivation and learning commitment. Therefore, in order to increase academic achievement in nursing college students, it is necessary to develop a specific strategy to improve learning motivation and to develop various activities and programs to immerse students in learning.
