The Contemporary animation style based on technology become various within some categories and genres as recreating the importance and meaning of many formalities. According to the variation of the contemporary animation style, The computer animation that has affected on continuous development of science and its following broad-band culture takes charge of the important position in producing the contemporary visual art. On this thesis, I will research < Ani-matrix > which has 9 episode each for the different Matrix world focused on its animation style. I will analyze their forms of expression into the both aspects of esthetics viewpoint technologically and film making style traditionally regarding to the matter of reality and reemergence on a viewpoint of a realistically esthetics. Also I will analyze mutual connection among the reinterpretation for the reality, philosophical message, and animation style within < Ani-Matrix> suggested by influence of Post-modernism. Thus, I intend to prospect the formation of animation style followed by its esthetics construction and effect on computer animation of the film genre.

This study takes a holistic approach to understanding the diffusion of IPTV services by combining the adoption-diffusion model and the use-diffusion model of innovation. IPTV service, a leading Digital converged application coupling media content with telecom, has been recently launched commercially in Korea. We created a structural model of adoption-diffusion, using the perceived ease-of-use and usefulness of TAM(Technology Acceptance Model) as mediating variables, and a structural model of use-diffusion, with the rate of use and the variety of use as mediating variables. To empirically analyze these models, non-users of IPTV were surveyed using the adoption-diffusion model to identity factors influencing their intention to subscribe to the service. Meanwhile, users of IPTV were surveyed using the use-diffusion model to determine the factors that influence their satisfaction with the service and their intention to fe-use it. Under the adoption-diffusion model, we found that trialability, household innovativeness and perceived risk were the determinants of user satisfaction with IPTV, and perceived ease-of-use, the mediating factors. Under the use-diffusion model, complementarity and communication were shown to be the determinants of users' satisfaction with IPTV, and variety of use, the mediating factor. We also found that consumers' intention to re-use IPTV was strongly influenced by its relative advantage and perceived risk.

The proposed new UCI syntax is compatible with the existing identifier and defines fixed length in such cases as printable ID, bar code and QR code which may entail better usage of identifier itself. For the compatibility, the identifiable metadata "key" is used for the existing UCI identifier and "UCI" element of metadata is defined for the new UCI identifier. The new UCI identifier plays roles of the resolution service and representation, and the old UCI identifier plays a role of internal DB management. Also, the object code has two types, meaningless and meaningful. The meaningful object code type can be used according the content classification standards in various field as comics, games, advertisement etc. The standardization activities can be supported by the root agency of UCI.

광기록의 역사는 1980년대초 Sony와 Philips가 공동 개발한 CD (compact disc: 640MB)의 출현으로부터 시작하여 1996년의 DVD (digital versatile disc: 4.7GB)를 거쳐 최근의 BD (Blu-ray disc: >20GB)에까지 이르고 있다. Read-only memory, recordable, rewritable 등 다양한 저장 및 재생방식이 존재하는데, 이는 레이저 조사에 의한 기록매체의 특성변화의 가역성 (reversibility)에 의존하므로 저장 및 재생방식에 따라 저장매체 또한 다르게 된다. 기록용량의 증가는 레이저의 파장이 짧아지고 동시에 사용된 렌즈의 개구수 (NA: Numerical aperture)가 증가함에 따른 빔 spot size의 감소에 기인한다. 회절한계를 극복하여 빔의 spot size를 줄이고자 하는 연구는 현재도 전세계적으로 활발히 이루어지고 있고 이러한 노력의 일환으로 어느 정도의 추가적인 저장용량 증가는 가능할 수 있으나, 2차원 방식으로는 대용량 광정보기록 (수백 GB ${\sim}$ TB급)의 실현은 불가능하다는 것이 일반적인 예상이다. 한편 장기적으로 기존의 2차원 정보기록방식을 대체하고 저장용량을 획기적으로 증가시킬 수 있는 bit-type 3차원 광정보기록의 개념이 1990년을 전.후로 처음으로 제시되었다. 이는 2차원 bit 정보가 수십 내지 수백 개의 다층 (multi-layer) 형태로 기록되는 방식인데, 그동안 산업체의 관심이 상대적으로 높지 않았던 이유는 영화, 음악 등 엔터테인먼트 시장성 확대를 위해 Blu-ray disc나 HD-DVD에 대한 연구개발에 치중해왔기 때문이다. 하지만 최근 급변하는 정보시스템 서비스 환경 속에서 정보유통량이 기하급수적으로 증가하고 있고 개인이 취급하는 정보량도 2010년경에는 수백 GB 단위가 될 것으로 예상되고 있으며 디지털 방송, 네트워크를 기반으로 한 서비스 수요 뿐 만 아니라 전자도서관이나 VOD (Video on Demand) 서비스 사업에 필수적인 수 TB급의 대용량 저장장치에 대한 수요 또한 크게 증가할 것으로 전망된다. 이에 따라 점차 그 물리적 한계에 다다르고 있는 기존의2차원 정보저장방식을 대체하고 저장용량을 획기적으로 증가시킬 수 있는3차원 정보기록(> $10^{13}$ $bits/cm^3$)에 대한 필요성이 대두된다.

Building a new library and remodeling an existing library for the multi-cultural space is a recent trend of the university libraries. That is, the spaces for using the digital and multimedia equipments, the rooms for reading and studying, the spaces for the cultural activities such as watching movies and holding an exhibition, and the spaces for the communication and refreshment are increasing in the libraries. However, this movement of securing and providing the new spaces is not closely connected with the off-line services and happens without the consideration of how to change the librarian's role and position. Therefore, the university libraries need to plan and provide the multi-learning space rather than the multi-cultural space considering the university library is an academic organization. Additionally, understanding the purpose of the university libraries, user's need, utilization method of books and considering the librarian's roles and placement are necessary in planning and providing the space of the libraries.

Recently, a drone is used for the general purpose application although the drone was builtfor the military purpose. A drone is actively used for the creation of contents, and an image acquisition. In this paper, we develop a 3D library module platform using 3D mesh model data, which is generated by a drone image and its point cloud. First, a lot of 2D image data are taken by a drone, and a point cloud data is generated from 2D drone images. A 3D mesh data is acquired from point cloud data. Then, we develop a service library platform using a transformed 3D data for multi-purpose uses. Our platform with 3D data can minimize the cost and time of contents creation for special effects during the production of a movie, drama, or documentary. Our platform can contribute the creation of experts for the digital contents production in the field of a realistic media, a special image, and exhibitions.

These days, with the advent of digital broadcasting, media environment offers users an opportunity to enjoy differentiated contents in a more aggressive fashion through user-media interactions based on computer technology. In fact, the development of contents which can induce spontaneous acts from users such as outdoor ads which use certain sensors and devices and exhibition halls has been active. With the development of low-price motion recognition devices, people have been able to enjoy diverse interaction-applied media by recognizing users' motion data without body contact. In this paper, we developed an interactive media player that can recognize the user's motion and control the video in the web service environment without installing a specific program. In addition, we set user motion recognition range and developed a user motion recognition algorithm suitable for the Leap Motion equipment installed in the kiosk. The results of this study can be experienced by various interactive media such as interactive tourism, education, and movie contents in kiosks that can be installed in public places.

Biographical information about people is usually collected and provided by a company or an institute which has a specific standard to select people for service. Recently, user oriented contents service like Wikipedia has started biographical information service, Wikipedia Biography Portal, in which users select people and freely describe about them. This study collected 500 biographical data from three categories of Wikipedia biography portal such as criminals, faculty, and directors. The contents of data from each category were analyzed with the word frequency and the divergence indicator to identify the characteristics of each category. As a result, divergency indicator is effective to represent the differential factors of each category. This study provides word clouds of top 100 word with divergence indicator and top 100 common words of three categories with word frequency as a guide for users to write about a person in these categories and for editors to accept and monitor the biography from users.
