정보를 생산하고 공유, 관리하는 방법이 디지털 방식으로 변경되고, 각종 문서의 정보들이 전자화된 문서로 변환되면서 활용도가 크게 높아졌을 뿐만 아니라 그 양도 증가함으로써, 모든 형태의 디지털 콘텐츠에 대한 효율적인 관리시스템을 필요로 하게 되었다. 콘텐츠관리시스템은 일관된 콘텐츠 저장 방법 및 관리 정책의 부재로 종합적인 콘텐츠 관리 및 콘텐츠 처리 지연과 콘텐츠의 질적인 저하를 가져오는 문제점이 있다. 본 논문에서는 멀티미디어 데이터를 효율적으로 처리하고 유비쿼터스 지식관리를 위한 ECM(Efficient Contents Management) 시스템을 제안하였다.

This paper presents an adaptive rate control scheme for streaming-based content sharing service. This scheme delivers multimedia contents from a user device to another device or seamlessly redirects streaming service across heterogeneous user devices. In the proposed scheme, a streaming server adjusts video quality level according to the network and client status. Our scheme is different from other rate control schemes, because the video quality at the server is decided not only based on the available bandwidth, but also based on the device characteristics and bandwidth requirement at the access network. We also propose a bandwidth estimation method to achieve more equitable bandwidth allocations among streaming flows competing for the same narrow link with different Round Trip Times (RTTs). Through the simulation, we prove that our scheme improves the network stability and the quality of streaming service by appropriately adjusting the quality of the video stream. The simulation results also demonstrate the ability of the proposed scheme in ensuring RTT-fairness while remaining throughput efficient.

With the continuous effort to make business management more efficient, companies have started to utilize smart workplaces and the incorporation of mobile devices. Furthermore, big data processing, using Database as a Service (DBaas), is also being researched for integration. Similarly. mobile cloud can be utilized to allow for data sharing among employees. In this paper, in order to solve the issue of efficiency in business management, a collaboration system for data sharing using mobile cloud environment is explored. The proposed system, looks to benefit the increased integration of environment and corporate public through use of standardized data, in a design capable of efficient integrated management system.

This paper deals with the result of an analysis on the effect of the power generation by municipal solid waste(MSW)-refuse derived fuel(RDF) and the introduction of tipping fee sharing between RDF manufacturing and power generation project. As a model case for the MSW generated at small and medium cities in our country, an analysis of the RDF power generation and Tipping fee sharing shows that 1) MSW amount of 7,800* $10^3 $t/y could produce 1,950*$10^3$t/y of RDF 2) Electric power generated by MSW-RDF could supply 290,000 households/year and 98,548 C-t/y of $CO_2$ could be reduced. 3) Tipping Fee should be shared by the considering of the contents of project of both side between RDF Production and power generation.

As knowledge-based society comes to the fore, sharing knowledge becomes a hot issue. Among various types of knowledge, a significance of software(applications) and contents is a huge in a current society. Moreover, along with appearance of smartphone, for instance iPhone, Application Store(also known as AppStore) utilized as a common gateway for sharing software and contents, brings a big interest for many users and developers. However, prior research to understand users' behavior on AppStore has been a scant. Therefore, the main purpose of this study is to investigate the impact of key smart service environmental factors on AppStore in order to empirically explain users' psychological feelings of intention to use AppStore. Based on a well-known technology adoption model, TAM, the study incorporates three main characteristics(user, society, and service) with six constructs(Innovation, Enjoyment, Subjective Norm, Information Level, Content variety, and Cost), influencing perceived usefulness, which then affects users' intention to use AppStore. Results provide evidence that support the tested hypotheses. The implications of the findings suggest a new theoretical work for future AppStore research and offers suggestions that the researchers and practitioners of AppStore should consider regarding the development of application and contents.

The propagation of smart devices and the rapid expansion of wireless mobile networks have increased the need for ubiquitous device connectivity and contents access. DLNA is currently being used as the de facto standard for connectivity of consumer devices in the digital home. The guidelines provided by DLNA are intended to facilitate device and contents discovery, management, sharing and distribution. However, consumer experience with DLNA has been rather poor and usability not up to speed. Different problems and issues in limited compatibility have been reported due to manufacturer customizations. Such compatibility issues are often difficult to identify by average consumers who are not savvy in information communications and multimedia technology. In this paper, the design and implementation of a DLNA protocol inspection tool is presented for compatibility analysis among DLNA certified devices. The tool monitors the home network and performs analysis of the underlying protocols used by DLNA. The tool can be used for diagnostics and troubleshooting, enabling the user to identify compatibility issues between devices or problems in the network.

OMA(Open Mobile Alliance 는 모바일 디바이스 분야에서 DRM 기술에 대한 가장 활발한 표준화 활용을 벌이고 있으며, 2007년에는 OMA-DRM v2.1 표준을 발표하였다. 이후 2009년에는 OMA-DRM v2.1의 확장이라고 할 수 있는 OMA-SRM(Secure Removable Media)과 SCE (Secure Contents Exchange)등 DRM 기술과 공유 모델에 대한 표준을 발표하였다. SCE는 사용자도메인을 구성하여 OMA-DRM v2.1에서 정의된 모바일 디바이스뿐만 아니라 일반 가전기기(Phone, PC, 카오디오 등)간의 콘텐츠 및 권리(Rights)를 공유할 수 있다. 본 논문에서는 OMA-DRM과 ACE의 기술과 공유 모델에 대하여 분석을 하고, 프록시 재 암호기법을 사용하여 공유된 콘텐츠와 권리를 이용하기 위한 각 개체들의 키 분배방법을 제시하고자 한다.

The information system fields of spatial applications have rapidly grown during the last decade in Korea. Spatial data has been produced for a variety of systems without common standards until national GIS Committee defined the data exchange formats among spatial databases in the middle of 1990's. It aimed at promoting data sharing between the different systems in similar application fields. However, a considerable number of databases built prior to the introduction of the standards are not yet standard compliant but still play the roles of the main producers/consumers in the data collection field such as early developed huge AM/FM systems maintained by governmental organizations. The strong autonomy of these databases keeps their own data models, formats and descriptions from being standardized, which leads the sharing to a more difficult stage. Sharing is another way of data acquisition with least efforts and time away from direct collection. A data clearinghouse is the core module which directs users to the relevant data resources. The contents of datasets should be described with predefined metadata standards for precise indexing. Moreover, a number of technical problems have to be resolved for the common use of data between heterogeneous spatial database systems. However, the technical issues can be covered by the present information technologies. The difficulties persist in the political/institutional issues. Institutional issues are derived from the diverse sources such as political background, governmental policies, related laws and/or regulations. The paper will firstly make an analysis of current situation in terms of Korean policies, laws and regulations, secondly abstract the institutional issues from the situation analysis, lastly present guidelines for promoting spatial data sharing in Korea.

Development of IT technology, in combination with the medical area, a number of developments have been made of the digital advanced medical devices, also increased interest in health, sharing of medical information has become increasingly necessary. Standardization for medical information sharing to satisfy these requirements have been studied. However, the medical information system is to build a system independent hospital itself, is difficult to share and exchange medical data with other medical institutions. In this paper, we provide a medical cloud system that can share medical information. Use DBaaS of cloud services. And is an international standard to have a HL7 share information by forming a meta-schema, each of the data transfer, the format of the document oriented data solves the heterogeneity between hospitals. Extracts the required field name of examination information, to exchange information with each of the local information and mapping. Health diagnostic information in the present study and diagnosis through accurate information sharing and exchange is possible ongoing management.
