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.

This paper proposes an experimental method for measuring the quality of experience to measure the influence of the participants' immersion, satisfaction, and presence according to the application of sensory effects to 360-degree video. Participants of the experiment watch 360-degree videos using HMD and receive sensory effects using scent diffusing devices and wind devices. Subsequently, a questionnaire was conducted on the degree of immersion, satisfaction, and present feelings for the video you watched. By analyzing the correlation of the survey results, we found that the provision of sensory effects satisfies the 360-degree video viewing, and the experimental method was appropriate. In addition, using the P.910 method, a result was derived that was not suitable for measuring the quality of the immersion and presence of 360-degree video according to the provision of sensory effects.

본 논문은 360도 동영상과 감각효과(Sensorial Effects)가 피실험자의 몰입도, 만족도, 실재감에 미치는 영향을 측정하기 위한 사용자 경험(Quality of Experience: QoE) 평가 실험 방법을 제안한다. 피실험자는 발향장치가 부착된 헤드 마운티드 디스플레이(Head Mounted Display: HMD)를 착용한 상태에서 감각효과가 동반된 360도 동영상을 경험한 후, 몰입도, 만족도, 실재감에 대한 설문에 응답한다. 응답 분석 결과 제안된 실험방법이 360도 VR 동영상과 감각효과에 대한 피실험자의 몰입도, 만족도, 실재감 등을 측정하기에 적합한 실험 방법임을 확인하였다. 반면, 360도 동영상을 시청하는 도중 비교 실험을 위한 회색 화면을 삽입하게 되면 몰입도와 실재감에 상당한 저하를 일으키는 것으로 파악되었다.

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 purpose of the present study was to investigate the influence of smartphone addiction on learning immersion, sociality and morality of college students and the present study is a descriptive survey research to investigate the influence of smartphone addiction on learning immersion, sociality and morality of college students. The subjects were 145 freshman, sophomore and junior students in the Department of Health at a college located in the Gyeongbuk region, and the data were collected from November 15 to 18, 2017. upon analyzing the correlations between the variables, a negative correlation was found between learning immersion and sociality and between learning immersion and morality, indicating that the learning immersion decreased as the sociality or morality increased. A positive correlation was found between sociality and morality, indicating that those who have a higher degree of sociality have a higher level of morality.

This study intends to propose an evaluation tool for analyzing the sense of immersion of realistic VR game contents in the metabus game industry, which is rapidly increasing recently. This paper presents an analysis tool to measure the degree of immersion after selecting three types VR games for research, and analyzing the immersion way method of the game. The research method analyzes how the user and the sense of immersion formed in the storytelling in the game can have an effect. Based on the results, we present an sense of immersion analysis and measurement method for evaluating the usability of VR game contents, which is a key element in the metaverse era. Furthermore, it expands the immersion element that appears in storytelling to the game industry and seeks a new direction of development through connection with the VR game industry.

Data for this study on computer game immersion were collected from 538 1st through 6th grade students with the use of questionnaires. Instruments included the computer immersion scale, and the self-concept, social avoidance and anxiety, aggression, and impulsiveness scales. Results showed that boys were more involved in computer games than girls, and 6th graders were more immersed than 1st through 5th graders. Self-concept, social anxiety, aggression, and impulsivity differed by degree of computer game immersion. Aggression was the most powerful explanation of computer game immersion. Children higher in impulsivity and social anxiety were more involved in computer games. Children higher in self-concept were less involved in computer games.

인터렉티브 아트는 관람객들과 상호 작용을 전제로 예술 작품을 구현하는 것으로 가상성, 몰입성, 상호작용성을 특징으로 한다. 그에 따라 관람객이 작품으로 몰입하게 하는 연구는 매우 중요하다. 현재까지 인터렉티브 아트분야에서, 몰입을 측정하기 위해서는 주로 설문지나 인터뷰, 정신 생리학적인 방법을 이용하였다. 그러나 이 방법들은 작품 관람 이후에 진행되어져서 정확한 몰입 측정이 어려우며 작품 관람에 방해를 줄 수 있다. 본 연구에서는 이를 개선하기 위해서 모바일 기기와 카메라를 이용하여 관람객들의 동선을 파악하고 관람시간을 중심으로 한 몰입 측정 방법을 제안한다. 본 논문은 작품의 몰입 정도를 파악하는데 도움을 제공한다.

The author has studied comparatively the sealing quality of conventional Z.O.E. cement, Kerr sealer and Nogenol sealer by means of penetration of 2% methylene blue solution through the root apex of human teeth in 72 cases as time elapsed. The results were as follows; 1. All the specimens, whose dye immersion time is two days, showed dye penetration of low degree unrelated to the kinds of root canal sealer. 2. Kerr sealer group, like conventional Z.O.E. group, showed dye penetration of high degree related to increased time of immersion in the dye. 3. In Nogenol group, there was slight increase in penetration related to increased time of immersion in the dye. 4. Kerr sealer group showed comparatively lower grade of dye penetration than conventional Z.O.E. and higher than Nogenel sealer.

Mass transfer characteristics during osmotic dehydration of carrots were studied as functions of immersion temperature and time, and sugar and salt concentrations. The effect of osmotic dehydration on the degree of browning of air-dried carrots was also evaluated. Increasing the immersion temperature and time, sugar concentration, and salt addition increased water loss, sugar gain, molality and rate of dehydration. The water loss and increases in solids, and molality were rapid in the beginning of the process and then increased slowly during remainder of the process. Increasing 1 or 2% salt concentration in the 40$^{\circ}$Brix sugar solution at 6$0^{\circ}C$ increased water loss and solid gain. Salt addition was not able to significantly affected on water loss and solid gain compare to temperature (40～8$0^{\circ}C$) and sugar concentration (20～60$^{\circ}$Brix) changes due to the low salt concentration. A minimum degree of browning of the air-dried carrots (O.D. = 0.048) could be achieved using binary solutions (40$^{\circ}$Brix sugar solution with 2% salt addition) with 24 min of immersion time compared to control (O.D. = 1.308) or blanching with 24 min of immersion time (O.D. = 0.174).
