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.

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 purposes of this study were to exploring the rural residents' satisfaction of living environment and social service. For these purpose we collected the data from the residents in rural area(1,000). The major findings of this study were as follows : First, the total satisfaction score is 58.9. The highest score group is housing and environment(69.9). And the lowest score group is cultural life and leisure environment. Various welfare services have been carried out for low income people, disabled people, old people, children and rural women within the social service system. But many respondents did not have chances to use social service because it was not efficiently provided many social services. So most of the residents in village wanted more welfare services. Second, the qualitative enhancement is more important than physical infrastructure expansion in order to improve rural settlement condition(housing quality, water supply and drainage, road and traffic system, medical care etc.)

The purpose of this study is to analyze the moderating effect of social support on the effect of the use of social services by the elderly with disabilities on life satisfaction.To this end, the 15th data of the Korean Welfare Panel 2020 were used to verify the characteristics, correlation, and multiple regression analysis of variables related to life satisfaction. The SPSS WIN 25.0 program was used. The survey subjects extracted 684 elderly people with disabilities aged 65 or older, and the use of welfare services was divided into income Service, health Service, home welfare Service, and social participation Service, and the analysis results are as follows. First, it was found that the experience of using welfare services for the elderly with disabilities had a positive (+) effect on life satisfaction. Second, social support showed a moderating effect on the effect of using welfare services for the elderly with disabilities on life satisfaction. Through these results, the necessity of practical intervention measures and development of various programs in social welfare policies that can improve the quality of welfare services for the elderly with disabilities and increase life satisfaction through various social support was suggested.

Three most popular information services, Periscope, Ustream, and YouNow, vicarious for all Social Live-Streaming Services (SLSSs), are investigated to analyze their streamers' motivations and the user-generated content. Additionally, we collected demographic data (gender and age). More than 7,500 streams by users from the U.S., Germany, and Japan were observed. Main streamer motivations on SLSSs are boredom, socializing, the need to reach a specific group, the need to communicate, and fun. Important content categories on all three SLSSs are chatting, sharing information, 24/7, and 'slice of life.' We were able to identify differences between users from the U.S., Germany, and Japan as well as between the users of Periscope, Ustream, and YouNow. The main motive to stream in the U.S. is to reach a specific group, while in Japan it is socializing, and in Germany boredom. The top content category for both, YouNow as well as Periscope, is to chat; on Ustream it is 24/7 (i.e., webcams).

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.

The purpose of this study is to predict the roles of public social workers and clarify their job. There were a few studies concerning them, and they suggested that it was needed to reform the delivery system or to supplement personnel. But they were almost normative. This study, based on the literature, analyzed public social workers' daily works to suggest their desirable roles. Generally the job of public social workers consists of two functions. One is income maintenance function, the other is social services function concerned with economically disadvantaged. The result showed that these functions were meshed up to now. Especially, It also showed that although they performed mostly eligibility work related public assistance and general practices, they wanted to perform professional practices. Took into account their working conditions, it seemed to be desirable to clarify their job. Thus, several suggestions based on these results are as follows: First, while eligibility functions are the central aspects of the public social worker's roles, it is needed for them to provide selected access services. Second, if they wanted to perform social services, it would be needed to restrict their roles for case manager and broker.

In recent years, social networks come into the spotlight as the important ways to find people or share information. Especially, existing social network services based on the Internet, such as Facebook.com and Cyworld.com, are now extended into the mobile environment. A mobile phone easily collects the personal information since it is carried by the user at all times, and various types of data can be gathered together with the advance of sensor technologies. These features differentiate the mobile social network services from the previous Internet-based services. In this paper, we estimate the user's mobile social contexts like closeness and relationship between the user and surrounding people using Bayesian networks. The mobile social contexts can be employed as important information for providing mobile social network services, and experimental results on real world data have verified their possibilities.

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.
