China has the largest number of the user of web 2.0 such as messengers and blogs, as of 2008 year. Chinese Internet digital market will grow from $85 billion in 2007 to $264 billion in 2015. The importance of Chinese Internet business is increasing, because of its size and growth potential. This research is focused on following two questions. First, what are the major characteristics of social networking services in China? In order to find out the answer about this question, the case study on Tencent QQ and Sina Poco, the most representative social networking services company in China, was done. And the reason of the use of social networking services, their contents, and the attitude toward the paid service were identified. Second, what are the major factors influencing the use of social networking services in China. User participation, network effect, usefulness, and system quality were inferred as the factors influencing the use. These factors were based on motivation theory, technology acceptance model, and the related research papers. This research model was proved by data analysis using Partial Least Square. As results, the use of social networking services was influenced by usefulness, network effect, user participation, and system quality. But social influence was not significant of the use of social networking services.

With the advancement in the area of cloud storage services as well as a tremendous growth of social networking sites, permission for one web service to act on the behalf of another has become increasingly vital as social Internet services such as blogs, photo sharing, and social networks. With this increased cross-site media sharing, there is a upscale of security implications and hence the need to formulate security protocols and considerations. Recently, OAuth, a new protocol for establishing identity management standards across services, is provided as an alternative way to share the user names and passwords, and expose personal information to attacks against on-line data and identities. Moreover, OwnCloud provides an enterprise file synchronizing and sharing that is hosted on user's data center, on user's servers, using user's storage. We propose a secure Social Networking Site (SSN) access based on OAuth implementation by combining two novel concepts of OAuth and OwnCloud. Security analysis and performance evaluation are given to validate the proposed scheme.

With the evolution of Internet technologies and the increasing variety of Internet devices, advertisements in various web services have also expanded. Interactive web services often go hand in hand with effective advertisements for a business model. We estimated statistical parameters of the interactive web server for service monitoring and advertisement-effect. In the web pages, we integrated the plugins of social networking services (SNSs) (e.g. Facebook, Twitter) and an advertisement scheme (e.g. Google AdSense) that regards social name-directory contents. Empirical data analysis and statistical results are presented with the implementation of estimations of parameters (e.g. utilization-level and serviceability) and advertisements in a social networking name-directory service (http://ktrip.net or http://한국.net). We found that estimated parameters were applicable to service monitoring of web-server as well as to synthesis of advertisement-effect in our social-web name-directory service.

최근 소셜 네트워킹 서비스(Social Networking Service)에 대한 산업계화 학계의 관심이 집중되고 있다. 그러나 소셜 네트워킹 서비스의 폭발적 성장을 가능케 한 동인과 비즈니스 모델에 대한 이해가 배재된 무분별한 모방만으로는 개방형 생태계의 성공적인 안착을 도모하기 어렵다. 따라서 본 연구는 소셜 네트워킹 서비스의 플랫폼 전략, 비즈니스 모델을 분석하여 웹 기반 플랫폼 서비스를 추구하는 사업자들에게 시사점을 제공하는 것을 주요 목적으로 한다. 소셜 네트워킹 플랫폼은 개인 이용자에게 자신의 개인 정보를 공유하고 갱신할 자발적 동기를 부여하였다는 측면에서 개인화 광고를 가능케 하여 양면시장의 다른 소비자인 광고주들에게 전폭적인 지지를 받고 있다. 소비자의 참여를 유도하여 양적 팽창을 가능케 한 동인은 이용자 간 상호작용 유도와 플랫폼의 개방성에 있으며 이 플랫폼은 향후 광고 시장뿐 아니라 통신시장에 편재된 개별 기업들의 고유 영역으로 그 영향력을 확장하고 있다. 따라서 포털 사업자, 네트워크 사업자들은 소셜 네트워킹 서비스를 단순히 새로운 웹 서비스로만 인지하는 수준에서 벗어나 개별 일반 소비자의 수요를 응집시킬 수 있는 서비스 플랫폼의 확산 방안을 도출하고 광고주들의 수요를 충족시키지 위해 미디어의 진화를 촉진시켜야 한다.

In this paper, we propose a multi-level content transmission mechanism for intelligent quality of service (QoS) in social networking services (SNSs). Because existing SNSs and related work send image content to a client with a single fixed mechanism, they cannot consistently support content accessibility according to different conditions of QoS factors such as network congestion and throughput. In the proposed image transmission mechanism, our communication middleware (CM) provides an SNS developer with three transmission modes so that an SNS server or client can dynamically change the quality of images if required. In each transmission mode, an SNS server can send images to a requesting client with original high quality, thumbnail quality, or send only text information. With varying qualities of downloaded images, an SNS developed on top of CM can provide users with consistent QoS for access to SNS content.

엔터프라즈 어플리케이션에 대한 요구 사항은 서비스와 가치의 입장에서 철저히 변화되고 있다. 최근 기업들은 기술과 고객과 마케팅 운영의 필요를 충족하는 서비스를 제공하기 위하여 설계된 조직체의 네트워크와 함께 결합하면서 이러한 어플리케이션들을 서비스 시스템으로써 보기 시작하였다. 소셜 네트워크는 이러한 방향에서 주요한 역할을 담당하며, 고객과 파트너 간의 견고한 관계를 세울 수 있는 결정적인 정보를 조직에 제공해줄 수 있다. 기업은 소셜 네트워크 서비스를 CRM과 같은 엔터프라이즈 어플리케이션들과 통합하여 이런 개념을 이용하기 시작하였다. 본 논문에서는, 오픈 소스 기반 소셜 네트워크 엔진과 CRM 어플리케이션을 결합하여 소셜 CRM 시스템을 구성하였다. 이를 통하여 고객들을 기업에 더 근접하게 이끌어 올 수 있게 되며, 고객들과 더욱 원활한 소통을 촉진할 수 있게 된다. 서비스 시스템의 효율성을 분석하기 위하여 소셜 네트워크 분석을 사용하였다. 경쟁적이고 경제적으로 도전적인 상황에서, 판매자는 빠르고 효과적으로 고객들과 의미있는 소통을 정착할 필요가 있다. 본 접근방법을 통하여 최소화된 시간 안에 변화하는 고객의 요구사항을 처리함으로써 이러한 이슈를 겨냥할 수 있으므로, 서비스 품질과 비즈니스의 가치를 향상할 수 있게 된다.

To stress the importance of privacy in social networking, I presented an analysis on how information control and information management vulnerability influence trust and privacy concerns in social networking, and how trust and privacy concerns influence the sustainable usage intention of social network services. I also analyzed the factors affecting privacy concerns to present the method to alleviate social network users' concerns about privacy. Information collection control, information processing control and information management vulnerability were chosen and analyzed as the factors affecting privacy concerns. The results showed that information collection control and information management vulnerability significantly affected trust and privacy concerns; and information processing control did not significantly affect privacy concerns. The relationship between trust and privacy concerns, and sustainable usage intention was statistically significant; and the relationship between trust and expansion of communication channels was also statistically significant.

The Internet of Things(IoT) is a new promising technology made from a variety of technology. The IoT links the objects or people, then enabling anytime, anywhere connectivity for anything and not only for anyone. Social networking services have changed the way people communicate. Recently, new research challenges in many areas of Internet of things and social networking services are fired. In this paper, we propose things recommendation method using social relationship in social Internet of Things. We study previous researches about social network service, IoT, and social IoT. We proposed SIoT_FW(Social IoT Friendship Weight) using static and a dynamic social friendship weight. Also, our method considers four social relationships (Ownership Object Relationship, Co-Location Object Relationship, Social Object Relationship, Parental Object Relationship). We presents a music device scenario using our proposed method.

Social networking services have changed the way people communicate. Rapid growth of information generated by social networking services requires effective search methods to give useful results. Over the last decade, social search methods have rapidly evolved. Traditional techniques become unqualified because they ignore social relation data. Existing social recommendation approaches consider social network structure, but social context has not been fully considered. Especially, the friend recommendation is an important feature of SNSs. People tend to trust the opinions of friends they know rather than the opinions of strangers. In this paper, we propose a levelized data processing method for social search in ubiquitous environment. We study previous researches about social search methods in ubiquitous environment. Our method is a new paradigm of levelelized data processing method which can utilize information in social networks, using location and friendship weight. Several experiments are performed and the results verify that the proposed method's performance is better than other existing method.
