The objective of this research is to analyze which functions make up web-based as well as mobile social media services and messengers. Services are clustered by their functionality. A total of 640 individual functions were identified, while investigating altogether 44 selected services in their web and mobile versions. Applying content analysis, functions were assigned to the services. The services were ranked by the number of implemented functions, and the functions were ranked by their occurrence in the services. Cluster analysis was applied to classify the services according to their functionality. Facebook and VKontakte were found to be the ones with the most functions; the most frequently implemented functions are support, profile, and account-related. Cluster analysis revealed six classes for mobile and seven classes for web applications. There is a noteworthy difference regarding the functionality scope between web and mobile applications of the same services. An example for this is Mendeley with 38 functions in the mobile and 91 functions in the web version. This is the first empirical attempt at clustering social media services based on their functionality.

Social networking service (SNS) is a service that allows people to share information, manage relationships with others, and express themselves on the Internet. The number of SNS users have increased explosively with the growth of mobile devices such as smartphones. As the influence of SNS has grown extensively, potential threats to privacy have also become pervasive. The purpose of this study is to empirically examine the main factors that affect users' intentions to use security functions provided by their SNS. The main theories for this study include the rational choice theory and the theory of planned behavior. This study has identified the factors that affect intention to use security functions. In addition, security function awareness and information security awareness are found to be important antecedents for intention to use security functions. The results of this study implies that when SNS providers develop security policies, they should consider the ways to improve users information security awareness and security function awareness simultaneously.

In recent years there has been an increasing amount of attention paid to outosourcing of information systems (IS) functions in organizations. The changing and more strategic role of outsourcing in business firms has been given much coverage in academic and trade publications. Trying to remain competitive and up-to-date in the rapidly developing world of computer technology is becoming a financial burden to many organizations in fields such as banking and financial services, health care, and manufacturing. Hiring outsiders to handle part or even all of its information services helps an organization provide better services and maintain a competitive advantage. This paper attempts to provide a benchmark of current IS outsourcing utilization in Korea. A detailed descriptive analysis of survey responses from 78 Korean companies indicates the usage, length of experience, expenditure of outsourcing, and kinds of IS functions being outsourced. The study also analyzes the effects (strategic, economic, and technological) of IS outsourcing with respect to the length of experience, expenditure of outsourcing, and kinds of IS functions being outsourced As a result of the analysis there are significant differences in the strategic, economic and technological effects of IS outsourcing with respect to the expenditure of outsourcing, kinds of IS functions being outsourced and firm size.

This study attempts to provide the foundation for a possibility that industrial su n.0, pporting organization can be strong information centers if they fortify their information dissemination activities, along with the basic functions. The following conclusions are resulted from the analysis in the operations of libraries, service methods and their publications of the information activities provided by the industrial su n.0, pporting organizations. First, the organizations have not be acquiring enough information materials. The services for bibliographic information should guarantee the uses of original documents. Second, the number of organizations providing on-line information services has been increasing, but the provided materials are nothing but their own materials produced during performing the basic functions. Third, the speedy information provision and efficient information dissemination for the end-users in the distance may be possible through on-line service, but it requires information analysis function to select the necessary information in our industrial environment. Forth, th information activities provided by the libraries of industrial su n.0, pporting organizations should be fortified.
