The development of ICT technology centered on mobile smart platforms have been emerging as a shared economic platform based on collaborative consumption. In this study, we analyze what factors affect success and failure in commercialized shared economic platforms from 2008 to 2016, and present what policy factors are needed to activate shared economic platform. To do this, we analyze successful cases of shared economic platforms and failed cases, derive key variables that affect success and failure, and conduct inductive analysis based on ID 3 algorithm based on them. Through this, we present the policy factors for the commercial success of the shared economic platform by deriving the rules for the success and failure of the shared economic platform.

Our Digital Carousel enables user to share media objects through media synchronization mechanism. We implemented the Digital Carousel so that the users participated in collaborative work may refer shared media or error objects as the same view to others. This paper explains the design and implementation of the EC_DXS(Error Control in Digital Carousel System). EC_DCS is a system that is suitable for detecting sharing and recovering software error based on multimedia CSCW(Computer Supportes Cooperated Work). With error sharing system, a group cooperating users can share me. applications. From the perspective of multimedia collaborative environment, an error application becomes another interactive presentation error is shared with participant engaged in a cooperative work.

The efficiency of the data share service of P2P method is decided by the maintaining guard method of a sharing list, This paper suggests the data sharing system of the P2P base that it should retain a shared data list at a client, The Server at a proposed system guards inclusively client. divided into several groups and at each individual group, a client appointed the TopHost uses the method guarding a free share list of a applicating group, The TopHost designs to execute it relating with server in case of the mergence and the division of a group as well as a maintaining management of a data share list, The efficiency of the suggested system regard the maintaining guard of groups formed of a client of the appropriate level of a kernel and exams examination to measure it through a really executed data share service.

This paper suggested a web based error manager for societal security service. This is a system that is suitable for detecting, sharing and recovering software error based on multimedia CSCW(Computer Supportes Cooperated Work). With error sharing system, a group cooperating users can share error applications. Our a web based error manager for societal security service enables user to share error objects through interaction awareness. This method has a file sharing, a window copy, a window overlay, or a window sharing. We implemented the web based error manager for societal security service so that the users participated in collaborative work may refer shared error objects as the same view to others.

This paper describes the design overview of shared file system $SANique^{TM}$ and proposes the method for detection of failure node and recovery management algorithm. We also illustrate the characteristics and system architecture of shared file system based on SAN. In order to provide uninterrupted service, the detection and recovery methods are proposed under the all possible system failures and natural disasters. The various kinds of system failures and disasters are characterized and then the detection and recovery method are proposed in each disconnected computing node group.

This study explore the perceived differences of factors influencing the shared accommodation in China, and the influencing paths of consumers' use of shared accommodation. This paper collects the questionnaire survey of the Chinese shared accommodation user and applies method of Amos V23.0. The results showed that perceived usefulness and perceived pleasure had positive effects on trust, and they also have indirect positive effects on perceived intention through trust, while perceived risk and perceived ease of use had no significant effects on trust. The conclusion is helpful to promote the long-term development of sharing accommodation companies by satisfying the needs of consumers from the point of view of consumers.

Recently, an idea has been suggested in which members construct the network by sharing their surplus bandwidth of their own access point. This kind of network is called public-shared network. As an application, SVC video streaming delivery system on public-shared network has been proposed. To send video stream from the stream server to clients, a tree structure is constructed where the root is a stream server, internal nodes are sharable access points, and leafs are clients. The previous researches have focused on constructing the minimal sharable-bandwidth tree which can serve all video streaming requests using the minimal sharable bandwidth. In this paper, we have shown that the problem of constructing a tree structure with given sharable access points to serve maximal video streaming requests is NP-hard. We also have developed an efficient heuristic algorithm for this problem and evaluated experimentally our algorithm.

Despite the rapid adoption of electronic journals, the need for print journals still remains. The current level of foreign journals acquisition poses a threat to strengthening the national research capabilities. Furthermore, there is too much overlap among academic libraries for foreign journals. We propose the establishment of government funded foreign research information centers to systematically acquire and distribute foreign print journals. We discuss specific approaches to selecting and operating such centers. Foreign research information centers are expected to enhance the national scholarly information infrastructure as well as the academic libraries' core capabilities.

실업계 고등학교 담임교사와 취업 지도 교사들은 서로의 취업 지도 경험과 정보를 공유하고 활용하는데 축적된 자료의 부족과 시스템의 미비로 많은 어려움을 겪고 학생들 역시 장소와 시간의 제약으로 현실에 맞는 취업 정보를 얻는데 한계가 있었다. 이에 본 논문에서는 취업 지도 시스템을 구현하여 취업관련 정보를 공유하고 시간과 공간적 제한을 극복해 취업 지도 과정을 간편하게 하는데 중점을 두고 향후 취업 지도 시스템에 대한 연구 방향을 제시하고자 한다.

Normally the 3rd grade class teachers at commercial rush schools suffer from coaching to selecting new employment of their students because of the lack of those data and systems. Also, the 3rd grade student are struggling for finding optimum information because there is hardly spare time and system for them So, in this article, the guideline for the new students employment-coaching system is described focused on simplification the coaching process by offering useful information and reducing time loss.
