Patterns for generating and consuming contents are various in these days from conventional broadcasting contents to UCC. There are many researches on developing recommendation engines based on user's profile for providing desired contents. In this paper we propose a contents recommendation system using not only user's profile but other's profiles in closed user group of the social network based on patterns for user's consuming contents. The proposed recommendation agent update user's profile using usage history and other's profiles related to the user in the closed user group.

University IT center usually has led IT system and headquarters have been working as a separate organization. If we apply the governance framework that is unique to the university system for IT governance in university IT project, IT transparency and efficiency are increased, and IT is no longer a simple tool but a university IT governance it will be stabilized. To improve existing problems, UCC was developed a unique framework of university organization based on CobiT Cube. So it can use effectively University IT on various side. I propose a method that can be applied to university information system sequentially through UCSP spiral process so that information service is classified into 5 areas and process is gradually applied.

With the advancement of internet and video compression technology, there has been an increasing demand for video, and producted a large quantity contents of UCC. Therefore, Semantic-sensitive retrieval and construction for digital video library is more in demand than ever. However, it is extremely difficult to categorize and label scenes in any video automatically for searching wanted scene. This study proposes a method to extract certain scenes and analyze the video content, and shows the experimental results after categorizing 5 sports news(soccer, baseball, golf, basketball, and volleyball).

This study examines user satisfaction and information behavior of information commons in the National Digital Library (NDL) of Korea through survey method. It analyzed service quality factors that affect the overall user satisfaction, and users' information behavior according to the physical spaces/facilities in the information commons. User satisfaction factors were developed to measure library satisfaction in all aspects of the eleven physical spaces/facilities of information commons service, and information behavior on eleven physical spaces/facilities in information commons were explored by users' character. According to survey findings, overall level of user satisfaction was maintained highly since the beginning of NDL. In particular, the facility of 'Productivity Computer Cluster' was ranked highest as 83.8 and the 'UCC Studio' was ranked lowest as 70.8 among the eleven facilities in information commons.

In this paper, we apply the next generation Internet Broadcasting Move Picture solution, FlashVideo has been designed and implemented. Currently being broadcast in the field to compress HD video in real time, as well as live Internet VOD services are available through the online system, the Internet LIVE broadcast and VOD service easy to operate and UCC services that support the solution. VOD video cameras and in real time using H264 CORECODEC to compress MPEC4, WMV, and real-time video streaming on the Internet, and phone system that supports the first, real-time recording of camera images featured nation's first real-time encoder system (Real time encoder system) is, Web and smart environment suitable for supporting the latest CORECODEC technology and software products. Second, the video can be played in MP4 player and customize your chat, and customizing is a possible two-way Internet Broadcasting System. Third, CMS (Contents Management System) feature video contents and course management contents in real time via the Android phone and iPhone streaming service is available.

Recently, the web 2.0 services which appear by exponential extension of the Internet can be expressed with the changes in the quality of structural evolution and in the quantity of increasing users. The structural base is in user participational architecture, the web 2.0 services such as Blog, UCC, SNS(Social Networking Service), Mash-up, Long tail, etc. play a important role in organization of web, and grouping and searching of user participational data in web 2.0 is broadly used by folksonomy. Folksonomy is a new form that categorizes by tags, not classic taxonomy skill. it is made by user participation. Searching based on tag is now done by a simple text or a tag cloud method. But searching to consider and express the relations among each tags is imperfect yet. Thus, this paper provides the relational searching based on tags using the relational graph of tags. It should improve the trust of the searching and provide the convenience of the searching.

This research focus on the economic activity as consumer and producer traits of future customers in the convergence age. We assess level of convergence for digital devices and services respectively by questionnaire survey and interview for 14 professions. And then, for evaluating convergence level and usage of digital services of each respondents, we conducted the questionnaire survey for 343 samples. Findings of our research hold that the group who showed higher level of convergence tends to use the socialized digital services more. Convergence generation were heavy users in appstore on smart-phone and wireless game and more participating. In digital service area, facebook/cyworld, twitter, UCC, portal, internet community in digital service. Convergence generation are global network communication, buying decision making activity, actively opinion expression, prosumer attitude, dependency on digital device, experience based purchase behavior, enthusiastic information sharing.

UCC(User Create Contents), UGC(User Generate Contents)의 높은 시장 확장은 인간의 창조적 능력과 창의적 생산 욕구와 맞물려가며 급성장하고 있으며, 웹 서비스의 형태도 사용자 중심의 구조와 환경을 구성해 나가는 방식으로 변화하고 있다. 이러한 사용자 중심 구성을 제공하기 위해 서비스 제공자는 서비스 배포자에게 웹 스크립트 언어 형태의 서비스 호출 코드 기반의 웹 서비스를 제공하고 있다. 본 논문에서는 웹 상에서의 스크립트 언어로 된 서비스 호출 코드에 대해 서비스 코드 제공자 및 서비스 배포자에 대해 관리 및 운영상의 효율성을 높일 수 있도록 단일 서비스 호출 코드 기반으로 제공할 수 있는 법을 제시하며, 본 논문에서 제시한 단일 서비스 호출 코드 기법의 효율성을 언급하고 있다. 또한 본 기법에 대한 활용 예시를 제공하고 있다.
