이동통신 서비스를 이용해 인터넷의 콘텐츠를 다운로드 받으면 통신비용이 자료의 양에 비례하여 사용자에게 부과된다. 각 Peer가 콘텐츠의 일부를 3G 채널 등을 이용하여 유료로 다운로드 받고 비용이 부과되지 않는 ad hoc 채널에서 콘텐츠의 나머지 부분을 다른 Peer와 교환하여 전체 콘텐츠를 구성하면 사용자에게 부과되는 비용을 절감할 수 있다. 본 논문은 각 사용자가 가지고 있는 일부의 콘텐츠를 교환하여 전체 콘텐츠를 구성하는 방법인 benefit value를 설명하고, benefit value 값이 변경되지 않아 전송횟수가 증가하는 현상을 benefit bitmap으로 해결할 수 있는 방법을 제안한다. 시뮬레이션 결과에 따르면 1Mbyte 파일을 5개의 Peer가 나누어 다운로드 받아 패킷을 512 byte와 1024 byte 크기로 교환했을 때, benefit bitmap을 사용하면 benefit value와 비교해 패킷 송신을 위한 버퍼의 크기가 100인 경우 약 22%, 버퍼가 3000인 경우 약 10% 정도 전송시간을 단축할 수 있다.

본 논문에서 제안하는 시스템은 특정 지역 내에 공청방송시스템과 인터넷 망이 설치되어 있다는 가정 하에서 콘텐츠 송출 시스템과 콘텐츠 분배기 및 TV 제어기로 구성된다. 이 시스템의 목적은 재난경보방송을 위한 긴급방송 콘텐츠를 송출하여 이를 TV를 통해 건물 내에 있는 사람들이 강제적으로 시청하게 함으로써 재난정보를 알리는 것이다. 그 지역 내의 일반적인 인프라와 경제적인 측면을 고려하여 콘텐츠 송출시스템과 콘텐츠 분배기는 LAN에 연결되며 콘텐츠 분배기와 TV 제어기는 RF로 연결되도록 구성하였으며, TV 제어기는 IR로 TV를 제어한다. 제안하는 시스템은 재난경보방송 외에도 안내정보 등을 공유하려는 목적으로도 다양하게 활용될 수 있다.

The successful quality factors to be successively sustainable excellent Festivals include ritual, experience, exhibition, sales, education, competitive, performance. In this study, Festival contents scales, that is named CONTSQUAL, being consisted of seven factors were drawn through the analysis of Cultural Tourism Festival 2012. Festival CONTSQUAL is ritual, experience, exhibition, sales, education, competitive, performance. The research sample is participants in the "Geumsan Insam Festival". Empirical analysis was carried out for visitors to verify the scales and research model. As a result, among festival CONTSQUAL, all components of qualities affected positively on Festival Flow but ritual and education. Festival flow affected positively on festival satisfaction while festival satisfaction affected positively on behavior intention. This study not only measured festival quality through the newly developed CONTSQUAL scales underlying sustainable competitive festival, but also built basic foundation for objectively assessing the festival contents quality, which would result in ensure successful local festival.

In this paper, we propose the techniques for effective management of profiles that necessary to provide adaptation content to an user. The profiles must be configured the related information of the user and can be exchanged according to periodic/aperiodic or event among user device, profile repository, contents adaptation server and contents storage server for providing adaptation content to an user. The profiles also must be supplied the contents services providers that need profiles for the adapted contents services. To support those function, we propose the management technologies of profiles and design profile framework supporting those. The proposed management framework of profiles is supported the profiles that are configurated using the various user's information and is used the Web Services for exchanging and providing regardless of the various devices and platform. The dynamic configuration method, metadata configuration method, and profiles providing methods using weight for effective management in the framework also are applied. The result of evaluation the proposed management techniques show effective profiles processing.

Recently, a hologram-like system to provide a realistic experience has been serviced in performances, exhibitions, education. The constructing method for the hologram-like system can be configured in various forms such as a pyramid-typed, a semi-transparent large screen form. However, in various types of hologram-like systems, it is difficult to provide adjustment by changing and revising the content according to the configured hardware characteristics. In this paper, we propose a novel technique that can automatically visualize virtual contents running on heterogeneous hologram-like systems. To change the content to a given hardware configuration, we receive pre-built simple text-based configuration data, and correcting process was performed. According to the results of this paper, we found automatically and easily corrected visualization with the given configuration of the hologram-like system. Also, the problem of reducing the time by manual control in various types of heterogeneous hologram systems was solved.

Antique maps are a cultural heritage of recorded information with distinguished pictorial and scientific value. They have been utilized in a variety of academic fields, especially in historical geography, as the most fundamental data to look into the restoration of space or historic changes of area from the past. However, there is no sufficient study on the development of contents using antique maps in the exhibitions. Furthermore, there is almost no content research on the antique maps integrating the academic programs in museums or art galleries. In particular, it is very difficult to find research on the approaches to configure or utilize the exhibition contents related to the Sea of Korea using European antique maps. This study examined the construction of educational contents in order to use the European antique maps including the Sea of Korea as well as Korea itself in the exhibitions. The results of this study may visualize the results of academic research on the territory and territorial waters of Korea and extensively acknowledge them as scientific data all over the world. Furthermore, this study aimed to create the opportunity to increase interest in the Sea of Korea and recognize it again, to find the contents construction to use European antique maps as academic data for exhibition and education in museums or cultural facilities and to provide a basic model for history education using antique maps.
