This study analyzed the usefulness of Web 2.0 techniques for improving archival information service. As a result, Web 2.0 was found to be useful for information service in National Archives of Korea(NAK). The results show that Open API is the most influential factor and RSS is the second-most useful factor for information services. These results can be used as a framework for developing Web 2.0-based information services in the NAK.

The purpose of this paper is to present a statistical model that can predict the rapid shift of users' attention by analyzing the lifecycle patterns of news in a social news aggregation service. Internet news service sites have a distinct characteristic in a sense that users' attention change very quickly in a short period of time. In this research, we propose a regression model for each news category which can model the decay pattern of users' attention and the content promotion policy of a social news aggregator is proven to be a major source of the rapid growth in the popularity of news. The proposed model is expected to be useful for evaluation of the social news aggregation service provider's content promotion policy that attempts to maximize users' attention as well as the diversity of news contents.

Recently the concept of Library 3.0 and its substance have been discussed by scholars and specialists along with Web 3.0. This study aims to analyze the debates on Library 3.0 and review the concept of Library 3.0. In addition, this study proposes library 3.0 service model based on its analysis. The keywords of in the proposed Library 3.0 model in this study is the Social Semantic Digital Library(SSDL), the Linked Library, and the Mobile Library. First, the SSDL means a real knowledge sharing and cooperation by applying both semantic web technology that which can manage data by machines and social networking services into e-libraries. Second, the Linked Library indicates that library resources become linked data that link libraries in all over the world. Finally, the Mobile Library refers to ubiquitous library equipped with RFID and mobile technology.

Web2.0의 고도화와 소셜미디어의 진화에 따라 웹 기반 콘텐츠에 대한 다양한 활용이 시도되고 있다. 또한, IPTV 부분에서는 기존의 TV기반에서 Web기반, Mobile기반 서비스로 확산되고 있다. 이러한 멀티디바이스 환경과 웹기반 콘텐츠의 IPTV 활용 서비스를 위해서는 콘텐츠에 대한 정의와 이를 표현하기 위한 메타데이터에 대한 정의가 필요하다. 이를 위해서 관련 표준화 단체를 분석한 후 이들이 제공하는 콘텐츠 메타데이터의 연관관계를 비교 분석하였다. IPTV 서비스를 위한 콘텐츠 메타데이터는 TV AnyTime Phase1 을 바탕으로 각 표준기구의 네트워크 상황과 서비스 방식에 따라 선택적으로 적용하고 있으며, VOD 서비스를 위해서는 CableLab의 ADI 메타데이터를 적용하고 있다. 향후 멀티디바이스 환경에서 IPTV 서비스를 위해서는 메타데이터에 대한 확장 연구가 필요하다.

This paper describes an advanced unified communication system. The advanced unified communications mean a service that integrates basic communications such as call, SMS, email, and chatting with social networking service considered as a new communication channel, presenting a unified user interface. The advanced unified communication system is composed of advanced UC(Unified Communications) applications, open UC service platform, and UC back-end servers. The advanced UC applications consist of web-based application and smart phone application. The open UC service platform provides a variety of service components that enable the third party applications to access basic communications and social network services within an enterprise. The UC back-end servers provide server functionalities for call, SMS, email, and chatting.

As the number of podcast users consistently increases which is rising as a new media along with the generalization of SNS and smart devices, the necessity for advanced search service is on the rise. This study designed and implemented a system which recommends a podcast to the users who search podcast by using their social network information. Suggested social network-based podcast search system (PODSSO) collects necessary podcast information only, analyzes social network of the users and makes the users have reliable and interested podcast search results.

Recently, comics pulication industry is experiencing long-time recess in Korean market. To overcome the difficulties firms are trying to develop various tools which fit new technological environments, but previous research tend to have focused too much on web-base contents such as webtoons, rather than communication effectiveness through social network services. Thus, this study investigated the relationship between the characteristics of postings at social network service and the consumer responsiveness. In the results, we found that posting with visual images and event invitations were positively associated with consumer responsiveness, and the amount of information was negatively associated with the responsiveness. This study shows some implications on how firms can effectively enhance communication with consumers through social network service.

An SNS(Social Network Service) enables people to form a social network on online as in the real world. With the rising popularity of the service, side effects of SNSs were issued. Therefore we propose and implement a policy-based privacy protection module and access control policy language for ensuring the right of control of personal information and sharing data among SNSs. The policy language for protecting privacy is based on an attribute-based access control model which grants an access to personal information based on a user's attributes. The policy language and the privacy protection module proposed to give the right of control of personal information to the owner, they can be adopted to other application domains in which privacy protection is needed as well as secure sharing data among SNSs.

최근 소셜 미디어(Social Media)라는 말은 컴퓨터 관련 연구분야에 종사하는 사람들 뿐만 아니라 일반 사람들도 모르는 사람이 없을만큼 중요하고, 많이 쓰이는 말이다. 본 연구에서는 인터넷과 통신기기의 발달로 이러한 소셜 미디어들이 사용자들이 감당할 수 없을 만큼 생성되지만 이러한 소셜 미디어를 어떻게 사용하고 효율적으로 묶어서 표현해야 하는지에 관한 연구이다. 소셜미디어의 종류에는 블로그, 소셜 네트워킹 서비스(SNS), 위키, UCC, 마이크로 블로그 등으로 나누어진다. 본 연구에서는 Social Media를 기반으로 Tangible Blog를 위한 콘텐츠를 저작하는 시스템에 관한 연구를 진행한다. 여기서 소셜미디어는 일반적으로 사용되는 사진, 동영상, 효과음, 텍스트에 3D Contents를 추가는 것을 목표로 한다. 3D Contents는 현재 게임분야에 많이 사용되고 있는 Kinect를 이용하여 생성하고 이러한 소셜 미디어들을 Web 환경에서 Authoring 하는 방법에 관한 연구를 소개한다. 최종적으로는 현재 많이 사용되고 있는 Blog의 형태에서 발전한 Tangible Blog를 만드는 것이 목표이다. 여기서 Tangible Blog는 기존의 텍스트, 음악, 동영상 등의 소스를 이용한 사용자의 일상생활 및 의견 표현을 넘어선 3D Contents의 활용, 스토리텔링 기법 활용 및 Sensory Effect를 활용한 실감 있는 블로그를 만드는 것을 목표로 한다.
