In this study, the importance-performance analysis (IPA) of the content components of remote graduate students was conducted. To this end, an online survey of 221 remote graduate students at J University obtained the following results. First, the importance of content components by area was in the order of learning content, interaction, teaching-learning strategy, and evaluation, and the degree of execution was in the order of teaching-learning strategy, interaction, evaluation, and learning content. Second, it was found that there were significant differences between importance and performance in the four areas of content components: learning content, teaching-learning strategy, interaction, and evaluation. The importance-execution analysis (IPA) was conducted in two dimensions: region-specific and item-specific, and the results are as follows. The learning content was found to be the maintenance area, the teaching-learning strategy and interaction were the key improvement areas, and the evaluation area was the overinvestment area. The results of this study can be used as basic data to diagnose the present of remote graduate school content and to gauge what needs to be improved in the future based on it.

이러닝 체제를 관리하는 기존의 LMS/LCMS는 동영상의 콘텐츠 운영시 교수 학습간에 학습자의 정확한 진도율 측정이 힘들고, 교수자와 학습자간 사이에 실시간성이 부족하며, 콘텐츠 내 다양한 인터랙티브 요소의 제공에 한계가 있다. 이 논문에서는 이러한 이러닝의 한계를 극복하기 위해 실시간 동영상 콘텐츠를 지원하는 학습관리 시스템으로 콘텐츠 연계를 위한 기술을 분석 설계하여 콘텐츠간의 연계기술을 제안하고 동영상 콘텐츠 운영을 위한 플랫폼을 제시하여 기존의 단점을 보완한다. 이를 바탕으로 한 LCM/LCMS 기반기술은 시간 공간적 제약을 극복해 실시간 상호작용이 원활한 사이버 학습도구로 마련될 것이다.

This paper proposes a educational content display system based on spatial augmented reality with a multi-touch screen for effective learning with intuitive interaction. It is hardly expected that the existing display systems have major learning effects because the user-system interaction can only be achieved through buttons or switches, In contrast, the system proposed by this paper ensures more effective interaction through the user's movement, not through buttons or switches. This system uses a spatial augmented reality method to display images, thereby attracting the users' attention. In addition, it ensures the effective dissemination of information by providing visual images that are more realistic.

As digital convergence evolves, it is expected that the market of IP-based services like VoIP and IPTV will be expanded. In particular, IPTV market is expected to attract consumers' attention through various interactive services offering a variety of experiences to consumers. Interactivity sets apart old media from new one in terms of how to mediate effects of user satisfaction. The object of this study is to investigate (1) multi-dimensional Interactivities in an interactive medium based on IP and relationship among them, and (2) significant factors affecting cognitive absorption of interactive media users. This study aims to provide implications on how to develop strategies for IP-based media including e-learning system.

This study examines the interaction effects between branded contents' ending types(happy ending, non-happy ending) and the level of product involvement(high involvement, low involvement) on consumer's negative responses. Results suggest that the level of product involvement had no significant effect on consumer responses since product on video clips was not closely linked to the contents' message. Selective empathy is identified as the happy ending type of branded contents had a greater effect on consumer's negative responses than the non-happy ending type of. It is an apparent new phenomenon shown among the young after 2000s. Moreover, the interaction between contents' ending types and the level of product involvement had a significant effect on consumer's negative responses. Two interaction terms (i.e. happy ending and low product involvement; non-happy ending and high product involvement) are the viable message strategies to weaken the consumer responses in terms of 'dislike'.

This study aims to explore the effects of interaction through UCC at online brand communication on scrap intention and visiting loyalty. According to study results, first, only information feature has positive effects on all interactions among quality feature of brand community; Second, confidence and responsiveness feature of brand community has positive effects on the connection feature among elements of interaction; Third, certainty has positive effects on activeness and connection among interaction elements. Fifth, while intention of sharing has positive effects on activeness and connection among interaction elements, it has no effects on the responsiveness. Finally, interaction does not affect the responsiveness of scrap intension, but has positive effects on visiting loyalty.

In this paper, we propose a novel model and effective authoring strategy of educational contents which improve the drilling effects in the cyber education through Internet. Especially we offer an authoring process of digital contents of engineering departs using JAVA component library technology and concept-based branch method, making the element of the library as unit-contents separated in accordance with their characteristics arid then accessing them at arbitrary instant in the replaying time. In proportion to the proposed model and strategy, the resultant contents shows advanced adaptabilities and interactions so that the contents can be user-oriented considerations. Combining and realizing the proposed authoring strategy for constitution of digital contents, we can get a more efficient scenario of making and drilling especially in the area of engineering or language courses.

초등학교 수학과의 학습은 학습자의 구체적인 조작을 통해서 개념을 학습하여야 한다. 웹에서 구현되는 콘텐츠들은 개념 학습을 위한 정의나 정적인 것이다. 이린 정적인 콘텐츠는 상호작용의 제약 조건이 많다. 이런 제약 조건을 극복하고 학생들의 인지적인 단계에 적합한 동적인 상호작용을 위한 콘텐츠 개발이 필요하다. 이에 본 연구에서는 수와 연산 영역의 교육과정을 분석을 통하여 객체와 클래스를 분석 설계한 이전의 연구에 이어 '수 클래스'를 구현하고 구현한 클래스를 활용하여 학생들의 자유로운 조작과 탐구활동을 통해 수와 연산의 개념과 원리를 학습할 수 있는 프로그램인 '수와 연산 학습 애플릿'을 개발하였다. 이것은 학생들의 동적인 상호 작용을 강하할 수 있다.

Recently, VR technology has been able to enjoy VR content using HMD due to changes in hardware and displays. VR video contents and HMD are becoming interactive through human senses and computer interfaces. Based on flow based on VR user's perspective, VR video contents and HMD were approached as subjects for continuous use. The components of the independent variable Flow were set up in real life, immersion, and interaction. Data from 400 male and female users of 450 users commissioned by the survey agency were used in the study. Research shows that first flow influences VR video contents and continuous use. Second, flow has been shown to affect HMD and its continued use. Among the flow factors that enhance the persistence of VR video content and HMD, which act as the greatest influence was studied. Through this research, the company aims to help establish direction of the next-generation VR industry
