This paper examines the rising value of social networked journalism and analyzes the case of a social news site based on the theory of networked journalism. Social networked journalism allows the public to be involved in every aspect of journalism production through crowd-sourcing and interactivity. The networking effect with the public is driving journalism to transform into a more open, more networked and more responsive venue. "wikitree" is a social networking news service on which anybody can write news and disseminate it via Facebook and Twitter. It is operated as an open sourced program which incorporates "Google Translate" to automatically convert all its content, enabling any global citizen with an Internet access to contribute news production and share either their own creative contents or generated contents from other sources. Since its inception, "wikitree global" site has been expanding its coverage rapidly with access points arising from 160 countries. Analyzing its international coverage by country and by news category as well as by the unique visit numbers via SNS, the results of the case study imply that networking with the global public can enhance news traffic to the social news site as well as to specific news items. The results also suggest that the utilization of Twitter and Facebook in social networked journalism can break the boundary between local and global public by extending news-gathering ability while growing audience's interest in the site, and engender a feasible business model for a local online journalism.

모바일 산업이 발달하면서 사람들은 개인간의 보다 섬세한 정보교환과 이로 인한 끈끈한 유대관계를 추구하게 되었다. 이러한 요구에 소셜 네트워킹 서비스 들이 단문 메시지 중심으로 활성화 되어 왔고, 스마트폰과 결합하면서 위치 정보를 추가하고자 하는 요구와 필요성이 문제시되고 있다. 그러나, 이러한 위치 정보는 민감한 정보이기 때문에 보안 및 프라이버시 문제가 대두되고 있다. 가족 구성원의 위치 정보를 공용 서버에 저장하는 것은 서비스 사용 활성화를 저해하는 요인이 될 수 있기 때문에, 본 논문에서는 가정내 홈 서버에서 사용할 수 있는 가정용 위치 정보 기반의 SNS 서비스를 제안하며, 사회의 가장 작은 구성 단위인 가정에서 가족 구성원들간의 친목과 유대관계를 증진시킬 수 있는 보다 공익적인 서비스를 제안하고자 한다.

A rapid increase was observed among individuals who want to communicate through a Social Networking Service (SNS). The increasing number of SNS users who create and share information resulted in a huge volume of SNS information. This deluge of information decreases the interest of SNS users, thereby prompting them to generate stimulating and exaggerated information to draw attention to themselves. This study aims to examine the effect of SNS users' desire for attention and share their tourism experience. This study utilizes use and gratification theory and investigates the moderating effect of gender. The analysis shows that the desire for attention influences sharing of tourism experience through compliance and identification at the level of SNS commitment. Gender difference was observed between compliance and identification. This study provides theoretical and practical implications based on the results.

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.

최근 소셜 네트워킹 서비스(SNS)의 급격한 성장과 함께, SNS를 대상으로 상품 마케팅을 하는 기업(광고주)들이 증가하고 있다. 이에 따라 SNS에서 상품을 효과적으로 광고할 수 있는 광고 대행 유저들을 광고주에게 추천해주는 서비스들이 등장하였다. 하지만 위와 같은 대부분의 서비스들은 단순히 유저의 이웃 수를 기반으로 유저의 광고 효과를 평가하기 때문에, 유저를 통해 단계적으로 파급되는 광고 효과는 고려하지 못한다는 한계를 가지고 있다. 위와 같은 문제를 해결하기 위해, 본 논문은 영향력 최대화 (Influence maximization) 연구 분야의 기술을 활용하여, (1) 유저를 통해 단계적으로 파급되는 광고 효과를 고려하는 광고효과 최대화 방안을 제안한다. 또한 보다 정확하게 광고효과를 평가하기 위해, (2) 광고 상품과 유저 사이의 적합도를 정의하여 광고 대행인 선출 과정에 적용하였다. 실세계 데이터를 이용한 실험을 통해 제안하는 광고 대행 유저 선출 방안이 전통적인 선출 방안들과 비교하여 광고 효과가 더 큰 유저들을 선출한다는 것을 입증하였다.

The use of SNS (Social Network Service) has been increasing in world society and the SNS has been used to satisfy different purposes of social groups over the years. In the beginning, the SNS were formed using e-mail, listserve, newsgroup, etc., where information was shared among relatively homogeneous groups of people. Now different groups including corporations have been using SNS such as personal web pages, blogs, Facebook and Twitter for their social media marketing. This study intends to verify the relationship between SNS use and export marketing performance. To achieve this, different types of SNS use were analyzed in order to verify their relationship with export marketing performance. The conceptual model is suggested in this paper and several research constructs are identified. The constructs used in this paper include export marketing performance, SNS use, degree of innovation, product online fitness, marketing competence, and internationalization competence. According to the results, the SNS use directly influences the export marketing performance. In addition, the factors which determine the level of SNS use are product's online fitness and organizational willingness to undertake innovation. Therefore, it is suggested to increase SNS use in different marketing purposes for future research.

The proliferation of using social media and social networking services affects the lifestyles of people. These phenomena are useful to companies that wish to promote and advertise new products or services through these social media; these social media venues also come with large amounts of user data. However, studies that analyze the data of social media within the perspective of information exchanges are hard to find. Much of the previous research in this area is focused on measuring the performance of exhibitions using general statistical approaches and piecemeal measures. Therefore, in this study, we want to analyze the characteristics of information exchanges in social media by using Twitter data sets, which are relating to the Mobile World Congress (MWC). Using this methodology provides exhibition organizers and exhibitors to objectively estimate the effect of social media, and establish strategies with social media use. Through a user network analysis, we additionally found that social attributes are as important as the popular attribute regarding the sustainability of information exchanges. Consequently, this research provides a network analysis using the data derived from the use of social media to communicate information regarding the MWC exhibition, and reveals the significance of social attributes such as the degree and the betweenness centrality regarding the sustainability of information exchanges.

최근 소셜 네트워킹, 멀티미디어 서비스의 사용량이 증가됨에 따라 인터넷의 트래픽은 이전보다 빠르게 증가되고 있다. 이에 링크나 노드의 failure 같은 네트워크 failure 발생은 서비스 이용자들에게 큰 영향을 미치게 된다. 이러한 failure로 부터 빠르게 회복하기 위한 다양한 Fast Reroute scheme들이 제안되었다. 하지만 이러한 Fast Reroute의 Back-path는 특정 링크에게 과도한 트래픽을 유발하게 된다. 본 논문에서는 이러한 점을 해결하기 위한 실제적인 Link Cost를 고려한 Load-Balancing기법을 제안한다. 실험결과 평균 degree가 높을수록 대체가능한 경로들이 증가되기 때문에 FIR에 비해 성능이 향상됨을 확인할 수 있었다.
