The present study has sought to explore the critical issues of English immersion education through the voices of the four elementary teachers who have recently taught at immersion programs under the guidance of Busan Metropolitan City Office of Education. The interview data with three teachers and the teaching journals of one teacher were analyzed and categorized into two emergent themes: (1) current difficulties in the immersion programs and (2) possible problems with the implementations of immersion programs in all public schools. Specifically, the first issue included teachers' inadequate teaching skills for immersion programs, accumulated learning losses, and lack of immersion class hours. The second issue included workload imposed on immersion program teachers, promotion of private education, learning losses of other subjects, and administration for show. Finally, pedagogical implications are suggested.

The purpose of the study is to analyze the impact of storytelling factor, technical factor and exhibition environment factor on the degree of satisfaction, degree of immersion and immersion types in and . Our findings show that the degree of satisfaction not only has a significant correlation with the degree of immersion, but also influences on the holding power and behavioral intention. According to the results of correlation analyses, three factors have an impact on the degree of satisfaction and immersion. Immersion factors influence negatively on Focused Attention and Heightened Enjoyment, however, the factors effect positively on Temporal Dissociation and Curiosity. As the influence of immersiveness on the degree of satisfaction and immersion, and immersion types have been verified, this study offers a fresh understanding of the importance of immersion factors as evaluation criteria for digital exhibitions.

In this paper, we analyze the immersion effects according to the level of map in adventure game. Computer games are actively enjoyed by many people around the world. Game players have frequently experienced the immersion which is an important aspect to be attained from games. However, it is not clear what immersion is and what kinds of factors influence to immersion. Nonetheless, in recent many researches, the elements of humanities and fun were found as factors of immersion in various digital contents such as game, virtual reality, cinema and etc. Therefore, today's games are developed on the basis of the humanities and fun theory that many researchers have been studied for a long time. In games, the balance of the level of map is related with immersion. Hence, it is important to know how the map patterns of game affect immersion of players. In this paper, we developed a 3D survival adventure game named by "1 Hour" using Unity3D in order to simulate how map patterns affect immersion of players. We also analyzed the relationship between the level of map and immersion using the game.

Immersion is a features of VR technology, and the most important condition for evaluating VR experience. With the improvement of VR technology, including the presentation accuracy of VR content, the degree of interaction is diversified, the user's immersion in VR equipment should not only be improved technically, but researched from the user's perception level. The paper defines two important factors, immersion and presence, in a participant's experience with a VR device. Although the current technology can already simulate the real environment information visually and audibly, the content of the VR environment is not enough for us to achieve a completely real experience. Based on the Flow theory of Csikszentmihalyi and the sensory immersion achieved by current technology, this paper proposes the key factors of how to achieve conscious immersion for users in VR media. We prove that immersion is an indicator of the true degree of sensory simulation of VR equipment and is the basis for the realization of flow experience. What really makes the participant feel a perfect experience is the content provided by the VR environment and gave participants a sense of presence, it is not limited to video or games. On the premise of the Multi-Sensory, Immersion, Interactivity and Imagination experience achieved by using virtual reality technology, combined with the content creation of flow theory, the interactive immersion achieved by users is an important method to realize the awareness immersion of VR equipment.

The turbine system converts the kinetic energy of water flow to electricity by rotating the rotor in a restricted waterway between the seabed and free surface. A turbine system's immersion depth and rotation direction are significantly critical in the turbine's performance along with the shape of the rotor. This study has investigated the hydrodynamic performance of the Savonius hydrokinetic turbine (SHT) according to the immersion depth and rotation direction using computational fluid dynamics (CFD) simulations. The instantaneous torque, torque coefficient, and power coefficients are calculated for the immersion ratios Z/D ranging [0.25, 3.0] and both clockwise (CW) and counterclockwise (CCW) rotations. A flow visualization around the rotor is shown to clarify the correlation between the turbine's performance and the flow field. The CFD simulations show that the CCW rotation produces a higher power at shallow immersion, while the CW rotation performs better at deeper immersion. The immersion ratio should be greater than the minimum of Z/D=1.0 to obtain the maximum power production regardless of the rotation direction.

Purpose: This study aimed to compare balance ability according to the immersion level of virtual reality-based training for the balance enhancement of the elderly. Methods: This study included 48 elderly people aged 65 years and older (male 16, female 32). According to the immersion level of applied virtual reality training, 16, 17, and 15 persons were randomly assigned to full immersion, semi-immersion, and control groups. The subjects who were assigned to the full immersion group and semi-immersion group received virtual reality training for 6 weeks at 20 min at a time, 3 times per week. The control group received no intervention. Balance ability was evaluated by measuring the stability limit and the tandem walking test before and after the intervention. Results: Results showed significant differences among the three groups in the limit of stability of all directions and the tandem walking test after the intervention. The results of the limit of stability showed a significantly higher value in the full-immersion group than in the control group, and the results of the tandem walking test showed a significantly lower value in the full-immersion and semi-immersion groups than in the control group. Conclusion: The results indicate that the head-mounted display equipment for applying full-immersion virtual training is the most effective in enhancing the balance ability of the elderly.
