Because the service is characterized by simultaneous production and consumption, the customer must participate directly in the delivery and production process of the service. For this reason, the variable Customer Participation has aggregated many empirical results in the service marketing field. Recent research on customer participation has focused on the relationship marketing, and is empirically identifying the relevance of customer participation and relative value of relationship marketing. These findings indicate that customer participation should be understood in a relationship between customers and service firms. Using commitment velocity and customer participation velocity considering dynamic of the relationship, this study aims to re-examine the relationship between customer participation and encounter satisfaction which is the foundation of relationship formation. Multiple regression analysis and hierarchical regression analysis are used as research methods. The study found that customer participation has a direct positive effect on encounter satisfaction, and that commitment velocity and customer participation velocity also have a significant effect on encounter satisfaction. However, all assumptions that were expected to moderate the impact of customer participation on encounter satisfaction were rejected. Although the study failed to identify the moderating role, it was clear about the impact on the encounter satisfaction of commitment velocity and customer participation velocity. Applying them to a wider variety of service types provided an opportunity to identify the value of the study, and to broaden the scope of the study suing these variables.

The purpose of this study is to investigate differences in learning flow and teaching presence according to the lecturer's appearance and the lecturer's speech rate. For this experiment, 183 freshman students from Xingtai University in China were selected as subjects of the experiment, and a total of four types of lecture videos were developed to test the lecturer's appearance and their speech rates. Data was analyzed through multivariate analysis of variance. According to the results of the analysis, first, learning flow and teaching presence of groups who experienced the presence of the lecturer appeared were significantly higher than the groups who learned without the appearance of the lecturer. Second, the groups who learned from videos with a fast speech rate showed higher learning flow and teaching presence than the group who learned at a slow speech rate. Third, there were no significant differences in both learning flow and teaching presence according to the lecturer's appearance and speech rate. This result provides a theoretical and practical basis for developing customized videos according to learners' characteristics.

This study identified the properties of online game, and analyzed existing studies on the impact of the properties of online game on flow. As a result, graphics, sounds, scenarios, game speed, manipulability, and item difficulty were identified as properties of online game, which were influential factors to flow. As a result, the hypotheses on scenarios, game speed, and item difficulty were adopted as significantly influential factors to flow, Attribute of online game. Meanwhile, the hypotheses on graphics, sounds, and manipulability, which were expected to significantly impact flow, were rejected.

체감형 게임의 재미를 극대화 하기 위해서 몰입감있는 게임화면이 제공되어야 한다. 곡면, 반구형 스크린은 일반 평면 스크린을 사용할 때 보다 더 높은 몰입감을 줄 수 있지만 투사시 생기는 왜곡영상 보정에 많은 계산이 요구되는 문제가 있다. 정지된 영상(프리젠테이션 화면)이나 비디오 영상은 메모리 버퍼링을 통해 시스템이 요구하는 속도를 보장할 수 있으나, 사용자와 상호작용이 요구되는 게임에서는 사용자의 반응을 처리한 후 매 프레임 마다 빠른 워핑(warping) 처리를 요구하게 되는데, 렌더링될 화면을 미리 보정할 수가 없기 때문에 시스템 처리속도 저하의 원인이 된다. 본 논문에서는 체감형 게임을 곡면에 투사하는 방법과 GPU를 이용한 빠른 영상 보정을 제안함으로써 게임에서 요구하는 처리 속도를 보장하고 고해상도의 게임화면을 사용할 수 있도록 했다. 웹카메라를 이용하여 스크린과 프로젝터될 영상간의 호모그래피(homographpy)를 정의해서 워핑했고 워핑 연산을 HLSL로 작성하여 GPU를 이용했다. 실험결과로 반구형 스크린에서 몰입감 있는 AR 탁구게임을 보인다.

21세기에 들어서면서 급속도로 성장한 한국의 게임 산업은 어느덧 국내에서 성숙기 단계를 맞이하고 있다. 또한 게임 산업의 꾸준한 확장을 위해서는 글로벌 시장에서 인정받을 수 있는 게임 개발이 절실히 요구되고 있다. 본 논문은 이를 위한 한 단계로서 MMORPG 장르의 게임 중에 오랫동안 이 분야에서 성공 가도를 달리고 있는 월드오브워크래프트를 몰입도 관점에서 성공 요인을 분석하고, 이를 바탕으로 2011년도에 주목 받고 있는 신생 게임 테라의 특징을 동일한 관점에서 분석한다. 몰입도 분석 방법은 정보이론과 정신물리학에 기반하며 게임의 레벨과 스킬의 개수에 의존적인 함수로서 정량적인 접근 방법을 제안한다. 제안 방법에 따르면 월드오브워크래프트는 확장팩 대격변을 전후하여 레벨에 따른 스킬 콘텐츠를 재배치하여 새로운 시도를 선보였다. 그 반면에 테라는 화려한 그래픽을 강점으로 내세우지만 낮은 몰입도와 레벨에 따른 스킬 콘텐츠가 부족하고 그 의도마저 모호하다. 이러한 특징은 실제 테라를 플레이할 때 나타나는데 월드오브워크래프트에 비해 상대적으로 단조로운 스킬 선택권과 직업 선택권의 형태로 발견되어지는 문제로서 제안하는 방법이 몰입도를 측정하는 하나의 방법으로 평가된다.

The purpose of this paper is to investigate which the nature of teacher behavior affects the learning flow in the context of military education. Empirical results show that the leadership of the nature of teacher behavior has a significant effect on three factors of learning flow (flow experience, transformation of time, concentration on task). In addition, the pace of class of the nature of teacher behavior is significantly related to the transformation of time and the concentration on task, and the sense of humor of the nature of teacher behavior significantly affects the concentration on task. The findings provide practical implications on how a military education institution strategically employes the leadership, the sense of humor, and the pace of class in an attempt to select and train instructors.

With the development of ICT technology, the game industry is growing rapidly. However, due to the excessive play of the game, there are cases where normal life is difficult. It is necessary to study the diagnosis and countermeasures against such game addiction. This paper study a system for diagnosing game addiction based on game usage information of game users. In order to develop a game addiction diagnostic system, this study classifies game addiction and abuse users and collects and models log information in real game environment. In addition, the addiction and good use model of game users was used as a knowledge to diagnose the addiction of new game users. Through the experiment, we could confirm the meaningful results. Also, according to the result of the diagnosis, the service such as SMS and reporting was suggested.

The virtual reality industry has an opportunity to take another leap forward with the surge in demand for non-face-to-face content and interest in the metaverse after Covid-19. Therefore, in order to popularize virtual reality content along with this trend, high-quality content production and storytelling research suitable for the characteristics of virtual reality should be continuously conducted. In order for content to which virtual reality characteristics are applied to be effectively produced through user feedback, a quantitative index that can evaluate the content is needed. In this study, the process of viewing virtual reality contents was analyzed and head movement was set as a quantitative indicator. Afterwards, the experimenter watched five animations and analyzed the correlation between recorded head movement information and immersion. As a result of the analysis, high immersion was shown when the head movement speed was relatively slow, and it was found that the head movement speed can be used significantly as an index indicating the degree of content immersion. The result derived in this way can be used as a quantitative indicator that can verify the validity of the storytelling method applied after the prototype is produced when the creator creates virtual reality content. This method can improve the quality of content by quickly identifying the problems of the proposed storytelling method and suggesting a better method. This study aims to contribute to the production of high-quality virtual reality content and the popularization of virtual reality content as a basic research to analyze immersion based on the quantitative indicator of head movement speed.
