Social networking service (SNS), which is based on the "six degree separation" theory, has gained its popularity in recent years. SNS creates a new way for maintaining relationship and sharing information over the virtual space. As a major branch, campus SNS provides a new platform for student to study as well as build and maintain inter-personal relationships. The highly realness of personal information and relatively strong group cohesion of campus SNS has turned it into an inevitable tool in students' daily life. The rapid growth of SNS in campus is creating huge academic and commercial benefits. However, little comprehensive research reveals what are determinant factors in driving students' intention to participate in campus SNS. In this paper, we conceptualize the participation of campus SNS as a social behavior and evaluate the impact made by social factors such as subjective norms and identity, as well as the impact of perceived reality and playfulness through an extended technology acceptance model.

In 21st century, According to development of Information Technology, It is clear that the importance of tourism information is extended increasingly. For this reason, It should be needed to realize a general system which make it possible to enjoy cyber tourism based on knowledge information system to recover a local potential growth power, catch a jumping chance again, and hold a new competitive power. But to discuss a tourism information system, the matters of hard ware, software and information mediating system should be reviewed generally, this research is likely to provide a cyber tourism information system through internet as a way of cyber tours through multimedia technology and stereoscopic image technique using GIS (Geographic Information System) centering on the networking system of tourism information. Constructing $\ulcorner$cyber touristy city$\lrcorner$ on internet, foster a new industry, to go balanced with a present tourism industry and experience a virtual reality, various theme tours create high profit to shrunken tourism industry.

The anatomic course of recurrent laryngeal nerve, its branch and its function were most significant for laryngeal, thyroid and tracheoesophageal surgery. Furthermore, the vocal cord palsy resulting from multi-etiology was serious complication and resulted in affecting the life quality. So, for the prevention of this complication, the concepts and knowledge about anatomic course and variants are very important. At now, most of anatomic courses and it's function has been identified precisely. But recently, the report about the anastomotic loops of both recurrent laryngeal nerve was published. In this study, we explored three cadevors for identifying the reality of the anastomotic loops between recurrent laryngeal nerves. Finally, we identified the cervicomediastinal anastomosis at tracheoesophageal groove in 2 of 3 cadevors that was confirmed by pathologic finding. This anatomic reliefs related to it's branch are extremely interest, although research is still in its initial phase. Our study will be extended toward histomorphometrical study and progressive electrophysiologic study, and we will be able io gather the largest amount of useful data regarding any possible use of this anatomic entity in future.

In reality, we can observe anomalous diffusion patterns of cycle-recycle or rejuvenation. Abrupt changes in the market environment such as sudden currency devaluation or change in government policy or those in marketing strategies such as drastic repositioning can lead to such atypical diffusion patterns. The authors present extended Bass models that incorporate effects of such abrupt changes of external factors into the hazard rate and the market potential. Using a set of compact-car data affected by a drastic change in the government policy, they illustrate the strengths of the proposed models.

The Late modem society have been changing in so complicated and diverse ways. Each unique parts of both culture and arts are interpenetrating as lowering high of u artistic boundaries lot better communication between environmental contexts in the concept of ‘intertextuality’. Contemporary Interior Design also has freed itself from a conventional boundary of field rather than stay in a single field, which is now shown to attempt a new style of design and expression style connecting itself it to other genre. So in this thesis ‘installation’does not mean a traditional field of arts but for building interior space with environmental area in extended context - place(hyper -reality ), tableau (medium) , transformation (expansion) . Contemporary Interior Design is expanding its range and enhancing its power of expression based on the installating concept and its expression style.

In this paper, we introduce ETRI AI Strategy #3, "Leading Future Technologies of Network, Media, and Content." Its first goal is "to innovate AI service technology to overcome the current limitations of AI technologies." Artificial intelligence (AI) services, such as self-driving cars and robots, are combinations of computing, network, AI algorithms, and other technologies. To develop AI services, we need to develop different types of network, media coding, and content creation technologies. Moreover, AI technologies are adopted in ICT technologies. Self-planning and self-managing networks and automatic content creation technologies using AI are being developed. This paper introduces the two directions of ETRI's ICT technology development plan for AI: ICT for AI and ICT by AI. The area of ICT for AI has only recently begun to develop. ETRI, the ICT leader, hopes to have opportunities for leadership in the second wave of AI services.

VRML(Virtual Reality Modeling Language)은 비/반몰입형 가상현실을 구축하기 위하여 널리 사용되는 언어이다. 그러나 이 언어는 키보드와 마우스 위주의 단순한 형태의 사용자 인터랙션만을 제공하기 때문에 다양하고 현실감 있는 가상환경을 구축하기엔 많은 제약이 따른다. 특히, 운전 시뮬레이션과 같이 확장된 사용자 인터랙션을 필요로 하는 가상 환경을 구축하기 위해서는 핸들/패달 장치를 이용할 수 있도록 하여 사용자에게 실제 상황과 흡사한 환경을 제공할 수 있어야 한다. 따라서 본 논문에서는 사용자 인터랙션을 확장하여 핸들/패달 장치를 이용할 수 있는 VRML 기반 운전 시뮬레이션을 구현하였다.

Engineering approach of statistics processing is defined for the statistical expert system. First, the engineering approach requirement are conceptualized by using an artificial intelligence in statistics, with the extensions being additional statistical knowlege engineering such as software engineering, optinal relationships, and the generalization abstraction. The methodology produces statistical expert system designes that are not only accurate representations of reality but also enough to accommodate future processing requirements. It also representions of knowledge that must be constructed, using the extended engineering processing model conceptualization and proposed engineering approach of the problem.

XR(가상 및 확장현실)에서의 리얼타임 그래픽은 조명이 제 역할을 하지 못하면 인물이 공간감이 느껴지지 않거나 스킨톤이 맞지 않아 이질감을 초래한다. 본 논문에서는 Art-Net 시스템을 활용하여 실제 조명과 가상조명에서의 배경 및 인물의 컬러를 동기화하는 방법을 제안하였다. 제안된 Art-Net 시스템을 통해 인물의 공간감을 향상 시킬 수 있을 뿐만 아니라 보는 이의 몰입감을 높였다.

본 논문은 제조 산업 현장에서의 업무 능력 향상을 위한 XR 교육훈련 콘텐츠의 가변적 시나리오를 제안한다. 가변적 시나리오를 적용한 XR 교육훈련 콘텐츠는 교육훈련 관리자가 자유롭게 시나리오를 가감할 수 있어 동일한 콘텐츠 내에서 다양한 시나리오로 콘텐츠를 구성할 수 있는 특징을 가진다. 이는 기존 하나의 시나리오로 반복되는 교육훈련의 한계를 해결할 수 있으며, 현장에서 발생할 수 있는 돌발적 상황 및 변화되는 업무 프로세스를 효과적으로 진행할 수 있을 것이다.
