The study empirically analyzed the effects of content attitudes and recall on digital signage advertising appeal (information appeal vs. image appeal) and interactivity level (low vs. high). As a result, first, it was found that a moderately low level of interactivity had a positive effect on content attitudes and recall than when the level of digital signage was extremely high. In addition, at moderately low levels of interactivity, information appeals had higher content attitudes and recalls than image appeals. Second, the content of image appeal has a positive effect on attitude when the digital signage level of interactivity is high, and the image recall ad and information appeal ad have negative effects on recall. Third, the low level of interactivity of digital signage has a positive effect on the content attitude and recall of information appeal. With the advent of digital media in recent years, concerns about how to construct the level of interactivity and information content on a strategic level are increasing in practice. The results of this study are expected to suggest the direction of the strategic grounds for this.

Tools and methods for interacting with the virtual environment are essential in order for a student to perform the virtual reality education contents. However, since the developed controller has generally been constructed for adults, it is necessary to study interaction tools considering the purpose of education and the level of students. Therefore, this study analyzed elementary and middle school students' perceptions of HMD and interactive tools, which are currently widely used as an initial research for developing interactive tools. Results show that students' perceptions has increased in post-questionnaire compared to pre-questionnaire, indicating that the universal controller can be used in the education. Implications for the development of interaction tools are discussed based on interviews with students.

This study is about the effect of interaction and flow of consumers within the company SNS on the consumers' affection. Verification took place through empirical analysis based on the theoretical background. The following is the summary of the research results generated based on the research results. First, correlation between aspect of the motivation for the use of contents and interactivity is as follows. Mutual sense of solidarity (Hypothesis 1-1), influence (Hypothesis 1-2), connectivity (Hypothesis 1-3) and reactivity (Hypothesis 1-4) exerted positive(+) on the interaction. Second, correlation between aspect of the motivation for the use of contents and flow is as follows. Mutual sense of solidarity (Hypothesis 2-1), influence (Hypothesis 2-2) and connectivity (Hypothesis 2-3) exerted positive(+) effect on immersion. Meanwhile, reactivity (Hypothesis 1-4) was not statistically significant when it comes to flow. Third, interaction between contents characteristics and interaction exerted positive(+) positive on the interactivity of entertainingness (Hypothesis 3-1) and informativity (Hypothesis 3-2). Fourth, correlation between contents characteristics and flow was examined, which demonstrated that only informativity (Hypothesis 4-2) exerted positive(+) effect on the immersion. Meanwhile, entertainingness was not statistically significant when it comes to the immersion. Lastly, correlation between interaction, flow and affection is as follows. Correlation between interactivity and flow(Hypothesis 5) was not statistically significant while interactivity(Hypothesis 6) and Flow(Hypothesis 7) exerted positive(+) effect on the affection. This study presents diverse implications and significances to the working level people who use the company SNS based on these results.

This study notices that corporate crisis spreading throughout society through SNS, according to the growing influence of online e-WOM on the basis Mobile and SNS. The study will prove that users' psychological tendencies can be affected by online e-WOM and played a role factors of crisis management on Facebook fanpage. This study conducted Facebook Fanpages users' perception of authenticity, Fanpage identification theory and interactivity affected Online e-WOM before a crisis, and authenticity, Fanpage identification theory and interactivity affected negative Online e-WOM after a crisis. The result through the sample of 290 men and women in their 20s and 30s who use a Facebook fanpage. found that Facebook fanpage users' perception of authenticity, Fanpage identification theory and interactivity affect on Online e-WOM before a crisis. On the other hand, the results found that Facebook fanpage users' perception of authenticity, and interactivity affect on Online e-WOM in caused crisis. Based on the results from the present study, suggested authenticity, Fanpage identification theory and Interactivity function in the aspect of the relationship marketing or crisis communication.

핵폐기물 지하처분, 지열개발, 지하 환경의 안전과 제어 등과 관련된 문제에 있어서 암석 및 암반의 역학적 거동 외에 열·수리·화학적 상호작용에 대한 이해가 필요하다. 이미 전세계적으로 국가별로 혹은 공동연구를 통하여 열·수리·역학적 상호작용에 관하여 많은 연구가 진행되었으며 최근 화학적 상호작용에 대한 문제가 추가적으로 제기되고 있다. 특히 장기간의 지하 환경의 안정성에 미치는 중요한 요소로 크립현상과 열·수리 화학적 상호작용 연구에 대한 필요성이 제기된 바 있다. 이 중 열·역학적 상호작용에 대해서는 현장문제에 적용 가능한 만은 연구결과가 제시된 바 있으나 기타 상호작용에 대해서는 다양한시험방법과모델링으로 인하여 아직가지 통일된 의견이 제시된 바 없다. 제 2주제에는 총 92편의 논문이 접수되었으며, 이 논문들의 내용, 성격, 해석방법 등을 간략히 정리하였다.

애드혹 유비쿼터스 컴퓨팅 환경에서 상호작용 미들웨어는 컨텍스트의 변화에 따라 애플리케이션간의 상호작용을 재구성할 수 있도록 지원해야 한다. 또한 미들웨어는 컨텍스트 인지 상호작용을 지원하는데 있어 컨텍스트 종류나 애플리케이션들 혹은 환경의 다양성에 따라 컨텍스트 변화에 대한 적응성을 동적으로 변화시킬 수 있도록 기능을 제공해야 한다. 하지만 기존 연구들은 컨텍스트 변화에 대한 적응성을 변화시키는 이러한 요소들에 대해 고려하지 않으며 그로 인해 컨텍스트 변화에 대한 적응 정도를 정적으로 설정함으로써 컨텍스트 인지 상호작용을 지원하는데 있어 경우에 따라 오버헤드가 발생하거나 컨텍스트 변화에 빠르게 대응하지 못한다. 따라서 본 연구는 애드혹 유비쿼터스 컴퓨팅 환경에서 동작하는 Publish/Subscribe 기반의 상호작용 미들웨어에서 이벤트 중계의 정확성과 컨텍스트 변화 적응성간의 관계를 기반으로 다양한 컨텍스트 종류나 사용자, 환경에 따라 이벤트 중계의 정확도를 동적으로 조절하는 기법을 제안한다. 그리고 이를 기반으로 이벤트 중계 정보를 동적으로 재구성하여 컨텍스트에 맞춰 효율적으로 컨텍스트 인지 상호작용을 구성할 수 있는 기법을 제안한다. 비교 분석 결과 기존 연구에 비해 컨텍스트 변화에 대한 적응성에서 더 나은 결과를 보여주었다.

This study examined the influence of child care teachers' playfulness on teacher-child interactions. The mediating influence of the teacher's efficacy on these relationships was also examined. The study subjects were 293 child care teachers in Busan and Gyeongnam. The collected data were analyzed with a structural equation model to verify the structures and paths among the variables overall. The results were as follows. First, teachers' playfulness directly affected the teacher-child interactions. Second, the teacher's efficacy had a direct effect on the teacher-child interactions. Third, teachers' playfulness not only influenced the teacher-child interactions directly but also influenced teacher-child interactions through the teacher's efficacy. The study concludes with a discussion of the implications of the influence of child care teachers' playfulness on teacher-child interactions mediated by the teacher's efficacy.

Mobile contents market is growing with the rapid adoption of smart-phones. Online access via mobile compared to PC-based online access, has distinctive service delivery characteristics which are ubiquitous connectivity and contextual offer. In addition, this study includes characteristics which are relatively disadvantageous for mobile services compared to PC-based services. These are response time and supporting non-verbal informations. This study investigates the influence of service delivery characteristics to perceived interactivity and mobile service attitude. The results show that mobile services' ubiquitous connectivity and contextual offer showed a positive relationship with the perceived interactivity of the mobile service. And the response time also showed a positive relationship with the perceived interactivity, but non-verbal information didn't. When the trade-off is met between response time and nonverbal information, mobile service developer should choose response time since it has positive effect on perceived interactivity and attitude.
