원룸 또는 오피스텔의 임대 비용이 상승함에 따라 개인 단독으로 거주 공간을 임대하는 것이 점차 어려워지고 있다. 따라서 대학생 또는 사회 초년생은 임대 비용을 절약하기 위하여 룸메이트를 구하여 공동으로 임대 비용을 지불함으로써 거주 비용을 줄이고 있다. 그러나 서로 다른 환경에서 자라온 사람들은 관심사나 취미가 다르기 때문에 같이 거주하면 다수의 생활 불편함이 발생한다. 이 논문에서는 이러한 문제를 해소하기 위하여 서로 간에 유사한 관심사를 가지고 있는 룸메이트를 연결시켜주기 위한 웹을 설계하고 구현한다. 제안한 웹은 취미나 습관 등을 저장한 사용자가 룸메이트를 구할 경우에 유사한 취미나 습관을 가지고 있는 사용자들을 연결시켜 준다.

This study examined the constitutional engineering of the Philippine democracy in terms of power sharing and accountability, and the effectiveness and stability of the Philippine democracy as a result were assessed. Based on the analysis, the nature of the present Philippine democratic system since 1986 was brought to light. This study argues that the system of power sharing between the President and the congress in the Philippines tends to serve for negotiating political interests among the power elites rather than functioning in a constructive way. And the public accountability system is not functioning as it was designed to do. Due to the defects the Philippine democracy continuously suffers the lack of political effectiveness and stability. Despite of the problem, the reason not to break down the system would be the fact that the system served for the oligarchic power elites to circulate and recreate the political power exclusively. The direction of the Philippine constitutional engineering should be weakening the present traditional elite dominated political system, and strengthening the chances of political participation from the various classes. Some concerned people suggested the constitutional change to parliamentary system in order to strengthening party politics, and federal system to cope with the problems of regional conflicts, but such efforts failed repeatedly due to the conflict of political interests. Considering the present circumstance, it would be advisable to reform political party law and election system in the direction of strengthening political party system, and to expand the scope of local government system in the direction of devolving the centralized political power.

This paper aims to study Thai democratic deepening and the constitutional engineering with the analytical concepts of 'power sharing' and 'accountability' focusing on the 1997 and 2007 Constitution. With regard to power sharing, the 1997 Constitution had the characteristics of majoritarian principle including a two-party system, strengthening of prime minister and the executive's power etc. It enhanced significantly the aspects of accountability compared with the previous constitutions. The institutions such as Constitutional Court, Commission on Election, Administration Court, Commission on Human Right, Ombudsman, Commission on Anti-corruption, and the Measure for Anti-money Laundering were established by the 1997 Constitution. However, such empowered accountability system were often abused by the political power groups in the political process. The 2007 Constitution has the characteristics of consensual principle including a multiparty system, proportional representation system, weakened prime minister's power, balancing of cabinet and parliament's power, pushing ahead with decentralization. However, the consensual principle of the 2007 Constitution came, in part, from the factional interests. It is similar to the 1997 Constitution in terms of accountability system, which enhanced in law but abused often in practice. One of the critical reasons for the failure of the 1997 and 2007 constitutions to consolidate democratic system was the political game played around the so-called network for the monarchy composed by the military, the civilian bureaucracy, Constitutional Court and the privileged classes. The future of the Thai democratic deepening depends on the constitutional engineering in which the factional interests should be excluded, and the rules of power sharing and accountability which traditionally played around the network for the monarchy should be effectively institutionalized.

This study aims to discuss the current status of the ride-sharing platform industry, which embodies the core values of the 4th Industrial Revolution, sharing and connectivity, as well as economic, industrial, and legal issues. To understand the position of competing groups, the research conducted extensive literature reviews on domestic and international cases of technical and legal issues of the sharing economy. The result indicates that the ride sharing industry showed the economy of synthesis in which production, supply, distribution, and consumption are on one platform. It made possible to share values to users and synthesize them with new services through easy-access mobile application technology. To resolve the conflicts between the taxi industry and the ride sharing industry, this study suggests the following: Ride-sharing companies should make contributions to provide legitimate services. The taxi industry needs to understand the value of the new industry and consumers who chose the shared platform service. The significance of the current study is that it proposed a comprehensive analysis and policy direction toward the issue of balance between public and private interests and legal stability.

Recent popularity of smart devices and social media seem to increase much interests on social learning, Despite of positive expectation on technology-based social learning, there are not many successful cases and practices of how to apply hands-on technologies and measure educational results. In this study, we tried to promote idea-sharing among learners in a classroom using web-based peer-review of assignments on a specific topic. Then we investigated effects of idea-sharing among learners in terms of individual knowledge construction. Experimental results show that idea-sharing promotes knowledge convergence and divergence, and then knowledge construction at learner's own.

Due to the emerging of high-speed network, lots of interests of access to remote data have increased. Those interests motivate using of Cooperative Caching that uses remote cache like local cache by sharing other clients' cache. The conventional algorithm like GMS(Global Memory Service) has some disadvantages that occurred bottleneck and decreasing performance because of exchanges of many messages to server or manager. On the other hand, Hint-based algorithm resolves a GMS's server bottleneck as each client has hint information of all blocks. But Hint-based algorithm also causes some problems such as inaccurate information in it, if it has too old hint information. In this paper, we offer the policy that supplement bottleneck and inaccuracy； by using file identifier that can search for the lookup table and by exchanging oldest block information between each client periodically.

The purpose of this study is to empirically examine a behavior improvement of unethical information sharing through the ethics program in organization. An unethical behavior of information sharing on organization members is to be get to private interests through divulgence of company's confidential information. An unethical information-sharing of individual is the opportunist and selfish behavior for an expansion of social capital and shows a negative ripple effect in organization. When conducting the research methods, the analysis order performs the cluster, discriminant, t-test and multiple regressions. According to the study, There are differences the behavior of unethical information sharing between opportunist and non-opportunist. The opportunist member for unethical behavior improvement required the program operation both value and compliance oriented program. Non-opportunist member required only the value-oriented program. The upcoming research needs to explore both ethics program's frequency and action of a punished person.

Forming a network, through Social Network Services (SNS), among a group of people who share the same hobby or interests could increase the information sharing among the members at an exponential rate. Moreover, SNS users' behavior extends beyond the traditional introverted consumption behavior to a proactive behavior by owning or actively sharing product information. For firms, such proactive consumer behavior translates into marketing effects such as the word of mouth (WOM) effect. Therefore, SNSs are accepted not only as a communications channel between firms and consumers but also as marketing channel, suggesting the possibility of a new revenue source. In this context, we will explore into the factors of SNS contents which conserve firms' image and product information, and effects of the factors on consumer attitude and WOM.

Despite various types of online social networks having different topological and functional characteristics, the kinds of online social networks considered in social recommendations are highly restricted. The pervasiveness of social networks has brought scholarly attention to expanding the scope of social recommendations into more diverse and less explored types of online social networks. As a preliminary attempt, this study examined the information-sharing patterns of a new type of online social network - unilateral (directed) network - and assessed the feasibility of the network as a useful information source. Specifically, this study mainly focused on the presence of shared interests in unilateral networks, because the shared information is the inevitable condition for utilizing the networks as a feasible source of personalized recommendations. As the results, we discovered that user pairs with direct and distant links shared significantly more similar information than the other non-connected pairs. Individual users' social properties were also significantly correlated with the degree of their information similarity with social connections. We also found the substitutability of online social networks for the top cohorts anonymously chosen by the collaborative filtering algorithm.
