Social collaboration and knowledge sharing among experts are the key characteristics of information system development projects. But the difficulty and complexity of communication may be the cause of the project failures. This study analyzes the influence of on-line social networking as communication system in information system development projects. A model has been developed to relate system, knowledge and social factors of on-line social networking to the performance of project members. Transactive Memory System (TMS), describing knowledge sharing process in human relationship, is used as a mediator. The analysis concludes that knowledge and social characteristics have positive effect on the members' performance, implying that the use of mobile devices and PCs as a social communication tool can be an effective way to enhance the possibility of project success.

This study is empirically intended to look into the effects of safety income system on recipient's economic independence and life satisfaction under the social security system. To achieve this, a survey was carried out to 650 adult householders benefiting from the social security system. The SPSS 23 statistical program was used to apply measurement variables related to the safety income system. The results of this study are summarized as follows. The social insurance and the social assistance of safety income system were adopted, having a significant effect on the economic independence. The effect of economic independence on life satisfaction was rejected, while the effect of social assistance on life satisfaction was adopted, showing a difference in the effect of each factor. The findings imply that social insurance and social assistance with support for safe income can be a positive help for economic independence, and unemployment benefit, national pension, long-term care subsidy and health insurance can help to achieve real economic independence, adopting only social assistance with limitation to life satisfaction. Consequently, the safety income system is very useful in helping recipients to achieve their economic independence through its introduction, but there is some distance to meet their life satisfaction.

The purpose of this study is to suggest a practical way to measure and report corporate social performance as public interest in corporate social value pursuits increases. In particular, we will look for ways to measure and report on the financial and social performance of a company based on the concept of the Double Bottom Line (DBL), which has recently spread to big companies. For this purpose, this study analyzed the theoretical background and practical techniques related to measuring and reporting corporate social performance, and examined methods for measuring and reporting social performance in the existing financial performance measurement system. As a result, SROI was the most suitable method for measuring social performance of a company. It is recommended that social performance reporting follows the disclosure method of the accounting system, and the details of reporting suggest that using the standard of GRI Standard, an international standard related to sustainability reporting, is the most reasonable alternative to 'Double Bottom Line' performance reporting.

This study analyzes the social function of democracy and the essential problems of social security of democracy. So far democracy has used a political term in politics. Democracy allows us the right to the freedom of individuality and social equality. Even scholars however, neglect to study about the criticism of democracy and social problems that are caused by democracy. It was expected that democracy would be valued by humans throughout the world. People have been fighting to establish a reliable political system of democracy. So they can have security in their society and the subject of politics. Therefore, We should consider study on democracy in function of democracy in relation to security of society and essential problems on what is democracy? Does democracy change with social change? Didier Bigo said, 'rising of freedom cause rising of a social unrest', B. Jeanneau said 'Democracy itself is the starting of social discord'. These are criticism of social security, the system and the function of democracy. It especially explains social discord and unrest that has occurred by an authoritative interpretation of democracy or the meaning of a word interpretation. It is a question of the day that it's converse the function of the system and the operation of democracy, act as social unrest.

Recently on IoT environment, there is necessary of protected network, which is only specific user can access it. Applying OAuth protocol on IoT, it can be easier to construct network authentication system, but it is hard to construct protected network authentication system. And there is weakness of OAuth protocol, which is easily attacked by sniffing Token by attacker. So, it is necessary to secondary authentication for OAuth. In ultimate IoT, the fog computing is essential. Fog computing is extension of cloud that enables networking not only in core system but also in edge system and communication node to node. Strength of fog computing is location awareness, support for mobility, and so on. If authentication in fog computing uses this strength, it can be more specialized in Fog Computing. So, in secondary Authentication, using Cyber-Physical-Social System will increase convenience of user than using existing authentication system, such as authentication certificate, id/password and group key, which is inconvenient for user. This study is about authentication based Cyber-Physical-Social System.

This study intended to analyze whether the system of voucher system, which was introduced as a policy tool to expand social services, was dependent or evolving through the research methodology of historical institutionalism. The voucher system is being introduced to emphasize the user's focus in the existing supplier-centered service provision system, but problems with the existing system have been found so far. We found that despite the shift in welfare paradigm from the remaining welfare supply to universal welfare in the past, the company was partially following the existing supplier-centered social service system. However, We found that new instruments for establishing legal systems and the path evolution factors are now being developed and matured within the voucher system. In other words, it was possible to predict that the voucher system would become more positive and mature in the future through logical changes in the system. Based on the results of the analysis of the voucher system, policy suggestions for policy values and objectives that were initially oriented toward the system were presented.
