In this paper we present the development of CITIS(Contractor Integrated Technical Information Service) reference model system which can be utilized for electronic commerce among enterprises. For the physical analysis target model, we selected switching system businesses of Korea Telecom. From analysis of life-cycle business process and data, we derived CITIS reference model containing CITIS To-Be model and CITIS scenario. Derived CITIS reference model is generalized so that it can be used not only for switching system businesses but other business areas regarding CITIS implementation. On the base of the derived CITIS reference model, We also developed CITIS information management system and CITIS-support workflow system as CITIS reference model system. Developed CITIS reference model system supports information and business process sharing among enterprises on internet and it does make a contribution to expansion of CITIS which is moving from conceptual research towards real implementation phase.

With the development of information and communication technology, we have been able to access and manage documents containing corporate information anytime and anywhere using smart devices. As the work environment changes to smart work, the scope of information distribution is expanded, and more efforts are needed to manage security. This paper proposes a file sharing system that enables users who have smart devices to manage and share files through mutual cooperation. Proposed file sharing system, the user can add a partner to share files with each other when uploading files kept by spliting the part of the file and the other uses an algorithm to store on the server. After converting the file to be uploaded to base64, it splits it into encrypted files among users, and then transmits it to the server when it wants to share. It is easy to manage and control files using dedicated application to view files and has high security. Using the system developed with proposed algorithm, it is possible to build a system with high efficiency even for SMEs(small and medium-sized enterprises) that can not pay much money for security.

Sharing knowledge is an important factor in the discourses on the knowledge management on the campus. This article analyzed the impact of organizational context on faculty's perceptions of knowledge-sharing capabilities in the university. As a result, perceptions of knowledge-sharing capabilities and performance-based reward systems were found to significantly affect faculty knowledge-sharing capabilities in the university studied. Also, results from multivariate analysis showed that the faculty's perception of knowledge-sharing more significantly affected knowledge-sharing than reward system.

The purposes of the study were to identify the characteristics and types of grey literatures, to investigate the factors restricting the sharing of grey literatures in Korea, and to make recommendations for the efficient collection and utilization system of grey literatures being produced and managed by either government agencies or government-supported research institutes in Korea. A survey instrument was designed to measure the current status of grey literature management systems and to elicit expert opinions from information professionals in information centers for an efficient system of grey literatures. It was found that information professionals considered the technical reports as the most important type of grey literatures, but maps and dissertations as the least important type of information value. Related to the participation for the central system of grey literatures, many respondents preferred to utilize the grey literatures owned by other information centers, but they showed a neutral interest level in sharing their information centers' grey literatures with other centers.

Children's play facilities have changed over a decade from the traditional play facilities in the front yard to the new type of commercial play facilities which install more exciting and enjoyable facilities, such as Kids Park. The more diversified in the type of facilities, the more difficult in the safety management by the existing system. The 'Safety Management System of Children's Play Facilities' of MOSPA(Ministry of Security and Public Administration) has provided the safety information uni-directly by government sector to the private communities. Recently, multi-directional information sharing methods, such as community mapping are adopted actively in the social activities which have common purpose for making the better community by information sharing with government and private sector. On the purpose of citizen's participation for safe play facilities and preventing accidents, this study investigated the status of child accidents and safety standards, especially focused on the children's play facilities. And the way for sharing safety information among the communities with the GIS mapping skills is suggested in the respect of more easily monitoring and practically inputting the comments on the status of management of play facilities by real users based on their experiences. It is expected that more activities from the private sector would participate to the safety management of children's play facilities by realizing the suggested system.

Currently, studies have show that the network related energy consumption are increasing. and part of overall energy consumption of our society are too. So, that is important to look for energy-efficient network applications and protocols. A most of network energy consumption are due to network edge devices. in this paper, in order to cut down the emissions of carbon dioxide from ICT business, which contributes 2% of the global energy consumption, it is necessary to understand energy consumption in peer-to-peer system. In this paper, in this paper we propose a architecture based on the introduction of a p2p proxy. The model is analyzed analytically and numerically to reveal how these factors influence the overall power consumption in both steady state and flash crowd information exchange scenarios. Specifically, our results show that the proxy-based solution can provide up to 50% reduction in the energy consumption and, at the same time, a significant reduction in the average file download time.

As the size of camera modules is decreasing and as the computing performance of portable devices is improving, taking photos has become a part of daily life. However, existing photo management programs and products that manage such photos still require extensive user effort to facilitate the sharing and browsing of images. It is especially difficult for novice users to manage and share photos. In this paper, we develop a round-robin concept-driven user preference feedback mechanism for achieving direct photo sharing, instant display, and easy management using optimized user controls and user preference-driven classification. Compared with commercial photo management systems, our proposed solution provides new features: optimized user controls, direct sharing and instant display, and user preference feedback driven classification. These new features boost the round-robin concept-driven user preference feedback. This paper proposes a photo finder that automatically searches for photos in storage spaces or cameras. The proposed photo finder relies on user preference feedback to share photos by leveraging user preferences, and the round-robin connection transmits photos to the family's digital photo frame or web album by arbiter. The proposed method saves time and spares users the effort required for photo management. Moreover, this method does not merely direct photo sharing and simple photo management, but it also increases the satisfaction level of users viewing the photos.
