Recently, digital contents have become increasingly perceived as a axe aspect of national development, and as such their generation and widespread promotion is being now pursued on a global basis, as govemment move to assist corporations in the realization of consistent industrial develo- pment. Efforts are also being made to seek avenues for the paid use of qualitativefy excellent contents, instead of relying upon traditional methods of free-of-charge provision. This paper examined the role of public institutions for the charging and development of contents industry. And it is suggested that promotional strategy and mode! for paid digital contents. ln particular, it is focused on those cases by the the Korea Institue of Science and Technology Information (KISTI) as a non-profit institution in public information sevice.

본 논문에서는 사료 검증을 바탕으로 반차도의 문화원형(文和元型, Culture Archetype) 가상복원을 통한 3D 증강현실 콘텐츠를 개발하였다. 반차도란 의궤에 담긴, 조선 시대 왕실의 행차를 그린 그림을 의미한다. 조선의 왕실문화를 활용한 궁궐콘텐츠는 한국 고유의 것이며, 스토리텔링이 풍부한 반차도를 활용한다면 국민의 전통문화 향유를 증대시킬 수 있다. 현대에서는 재현행사를 통해 왕실의 행차를 재현하고 있지만, 실내에서는 재현하기 어려워 왕실 행차에 대한 문화유산 접근성이 낮다는 한계가 있다. 또한, 문화콘텐츠닷컴과 국립중앙박물관에서 제공하는 반차도 관련 멀티미디어 콘텐츠는 반차도 구성을 설명하는 것이 아니므로 심도 있는 반차도 학습에 어려움이 따른다. 이를 극복하고자 본 논문에서는 사료 고증 메타데이터에 기반을 두어 문화원형 가상복원 3D 증강현실 콘텐츠를 제안하고자 한다. 이를 토대로 문화원형 가상복원을 위한 3D 증강현실 콘텐츠의 활용 가능 모습을 살펴보고, 기록유산 반차도의 문화원형 가상복원기반 증강현실 3D 콘텐츠를 제안하다.

Although the amount of UCC(user created content) rapidly grows nowadays, there are various problems in authoring, distribution and management of this abundant content because the platforms for fabrication and replaying content are not compatible and the authoring environments are not sufficiently interoperable with other site or with each other. In this paper, we propose a CPMS(content publication and management system) scheme improved in interoperability to solve these problems, and we design a novel system enhancing the efficiency and speed of content distribution and management by minimizing the repetitions in the processes of production, reshaping, and publication. Moreover the proposed system adopts an improved content management technology by changing from simple point-to-point method to the centralized distribution method, and as for the service scheme, we change from the site link method to the database link method, and we also take duplex interlink scheme instead of simplex one. We finally compare the proposed system to the conventional ones as points of view of compatibility and interoperability to prove the improved performance of our system.

The importance of cultural contents industry is steadily growing owing to the Korean wave etc. and Buddhist cultural contents is a part of the cultural contents. However, the development of Buddhist cultural contents in many ways has left much to be desired. That is because, it is difficult for the public, who is not Buddhist scholar, to understand and take interest in conventional contents on Buddhist books themselves which are digitalized. Also, most contents researches are discussed on the necessity of contents development and just stay in these subjects, but it is insufficient to study a semantic analysis and visualizing contents on Buddhist books. So, in this paper, we analyse mandala's twinning rite in the Buddhist books and implement visual contents on the rite. The mandala is using toohadeokbul in a special way as the abhisinca rite. We analyse concept of the toohadeokbul and implement its visual contents which visualize ideological logic of Buddhism. The implemented contents are able to provide the public with Buddhist cultural experience of the yard. Additional, by trying to visualize descriptive expressions of Buddhist books, this paper could be a precedent for developing visual contents of unlimited data comprised in Buddhist books.

CDN(Content Delivery Network) has been used as contents transmission network for transmitting high capacity contents fastly and stably. Main goals of CDN are efficient distribution and management high capacity contents. Current CDN distributes contents by managing contents based on basic metadata created by contents provider. However, existing CDN management system doesn't provide a method for applying additional metadata in content itself that is necessary for efficient contents management and distribution. Since the existing system can not annotate additional information in metadata about contents itself, and can not search contents that user wants. This paper proposes a method for applying additional metadata in existing CDN and implemented it as contents metadata management system(CMMS). A user can search needed contents effectively via CMMS. Also, the searched result can help selecting and managing contents to distribute in CDN.

There are many and various devices like sensors, displays, smart phone, etc. in smart environment. And contents can be provided by using these devices. Vast amounts of contents are provided to users, but in most environments, there are no regard for user or some simple elements like location and time are regarded. So there's a limit to provide meaningful contents to users. In this paper, I suggest the contents recommendation system that can recommend contents to users by reasoning context of users, devices and contents. The contents recommendation system suggested in this paper recommend the contents by calculating the user preferences using the situation reasoned with the contextual data acquired from various devices and the user profile received from the user directly. To organize this process, the method on how to model ontology with domain knowledge and how to design and develop the contents recommendation system are discussed in this paper. And an application of the contents recommendation system in Centum City, Busan is introduced. Then, the evaluation methods how the contents recommendation system is evaluated are explained. The evaluation result shows that the mean absolute error is 0.8730, which shows the excellent performance of the proposed contents recommendation system.

Mobile game have an advantage of mobility, portability, and simple interface. These advantages are useful for gesture recognition based game which should not have much content quantity and complex interface. This paper suggests gesture recognition based mobile game content with user movement could be applied directly to the mobile game wherever recognition system is equipped. Gesture is recognized by obtaining user area in image from the depth image of TOF camera and going through SVM(Support Vectorn Machine) using EOH(Edge Of Histogram) features of user area. And we confirmed that gesture recognition can be utilized to user input of mobile game content. Proposed technique can be applied to a variety of content, but this paper shows a simple way of game contents which is consisted of moving and jumping newly.

This paper focuses on the systematic conceptualization of the 'contents' through the differentiation between the meanings of the work of art and the contents. The 'contents' are referred to as various media products, but they are all the audience-oriented work of art. From the beginning of its birth the film medium turned out to be a kind of contents, which is involved in the specific role of audience. It also implies that the film medium could not exist without the interaction of the media text and audience. In order to understand this context, this paper analyzes the film of Alfred Hitchcock.

콘텐츠의 네트워크를 통한 배포가 늘어나면서 콘텐츠의 보안에도 많은 연구가 활발히 진행되고 있다. 이러한 콘텐츠 보안은 콘텐츠 자체에 보안을 설정하거나 콘텐츠를 볼 수 있는 프로그램 등에 보안을 설정하는 방법 등을 사용하고 있다. 여러 가지 보안 기술 중 워터마크는 불법 콘텐츠 유포의 방지, 불법 콘텐츠의 추적, 저작권 주장, 위 변조 방지 등에 사용되고 있다. 워터마크는 위 변조를 방지하는 목적에서는 잘 훼손되도록 제작되지만 저작권 보호의 목적에서는 훼손되면 안 된다. 그러나 콘텐츠의 유통 과정 중 워터마크는 훼손되기 쉽다. 콘텐츠를 제작하는 과정에서 워터마크가 삽입되면 콘텐츠의 압축, 편집, 송출 등의 단계에서 공격을 받아 훼손될 수 있기 때문이다. 이러한 공격에서 워터마크를 살아남게 하기 위해서 본 논문에서는 움직임 예측을 이용한 워터마크 삽입 방법을 제안한다. 방법은 워터마크 메시지를 삽입할 때 움직임이 있다면 그 부분에 좀 더 강하게 워터마크 메시지를 삽입하도록 하는 것이다. 실험 결과 이러한 방법으로 워터마크를 삽입할 경우 워터마크가 좀 더 잘 검출됨을 확인할 수 있었다. 제안하는 내용은 콘텐츠 보안이 필요한 VOD, IP-TV, DMB, FTA(Free-to-Air) 방송 등에 사용될 수 있을 것이다.

본 논문은 무선 인터넷 환경에서 사용자의 편의와 상호 운용성을 고려해서 유선상의 HTML 프레임 콘텐츠를 변환시키는 프레임 지원 HTML 변환기의 설계 및 구현에 대해 기술한다. 구현된 HTML 변환기는 일반 텍스트 콘텐츠의 경우, 일대일 태그 매핑을 통해 WML 콘텐츠로 변환이 된다. 프레임으로 구성된 콘텐츠는 프레임 콘텐츠 재구성 모듈에서 일련의 재구성 과정을 거친 후에 대부분의 프레임 콘텐츠가 여러 메뉴에 대해서 보여지는 타겟 프레임은 하나로 고정되어 있는 것을 고려해서 무선 단말기의 화면에 1행 2열의 테이블 형태의 WML 콘텐츠로 변환이 된다. 즉 좌측열에는 여러 메뉴 콘텐츠를 우측열에는 타겟 프레임에 보여지게 되는 콘텐츠를 위치 시킴으로해서 프레임 콘텐츠의 변환을 수행한다. 추가적으로 이미지 맵이 포함된 콘텐츠의 변환은 이미지 맵 관련 태그를 파싱한 후, 링크되어 있는 HTML 문서의 이름을 추출해서 WML 콘텐츠 데이터로 대체하고, 해당 콘텐츠로 링크시킴으로써 변환이 가능하게 한다.
