This paper proposes a frame work for embedded system management. The management system can automatically monitor and maintain the Internet connected embedded-systems such as sensor devices, set-top box, web-pad, information appliances, PDA, etc. Users can easily diagnose system state, resolve system problems, maintain and update applications, and back up user information using the management system. We implement prototype for the management system on embedded Linux system and High -available Linux system.

EDMS systems have been a main alternative for enterprise content management (ECM), which provide valuable functions for the effective control and management of organization-level digital contents. However, it has not been effective frequently for the purpose of integrative control of overall contents in an organization. One of reasons for this problem is that individuals usually create and store files with their own personal computers and do not move them to the central storage and control device, EDMS. Many occasions show that this situation can cause undesirable results for better management of enterprise contents. This paper introduced an approach of virtual folder which can directly connect individual computers and EDMS storage device without users' inconvenience. Adding the capacity of restricting usage of individual computer, users unavoidably and conveniently store and retrieve digital contents using EDMS server system. Several modules and implementing architecture for the virtual folder system are shown and the results of utilizing the system are explained with a case of application.

The rapidly increasing use of the Internet and advancement of the communication network, the explosive growth of digital contents from personal home pages to professional information service the emerging file exchange service and the development of hacking techniques . these are some of the trends contributing to the spread of illegal reproduction and distribution of digital contents, thus threatening the exclusive copyrights of the creative works that should be legally protected Accordingly, there is urgent need for a digital copyright management system designed to provide centralized management while playing the role of bridge between the copyright owners and users for smooth trading of the rights to digital contents, reliable billing, security measures, and monitoring of illegal use. Therefore, in this study, I examined the requirements of laws and systems for the introduction of the centralized management system to support smooth distribution of digital contents, and also researched on the current status of domestic and international centralized management system for copyrights. Furthermore, 1 tried to provide basic materials for the standardization of digital contents copyright management information through the examination of the essential elements of the centralized digital contents management such as the system for unique identification the standardization for data elements, and the digital rights management (DHM) .

Currently for the development of internet and network technology, since request of service for the large volume multimedia data has been more increased, multimedia users want the convenience and accuracy of multimedia service system about storing and retrieving of the multimedia contents. To satisfy the request of users, metadata management for the diverse information of multimedia contents is very important. However, the metadata management for the multimedia contents is difficult because the metadata standards are different each other for the type of multimedia data and service. In this paper, we propose the integration metadata management system structure which extends previous metadata management system based on text for the multimedia contents metadata which are expressed differently each other according to the multimedia data or service type.

With the spread of computer and development of internet service, the varied contents and digital data has been produced, then provided. The digital contents are more efficiently able to be created, produced, provided as well as distributed, on the other hand, its own copyrights seem to be more easily broken than analogue contents due to the convenience to make copies of original contents. Therefore, protecting copyrights recently become the key issue. DRM(Digital Rights Management) is the current technology to protect digital contents from duplication but it sometimes causes problems in the key-management. In this thesis, we would first like to analyze DRM and find out some trouble in the key-management of it. Finally, we will show CDMS(CEK Distributed Management System) to improve DRM out of the key-management problem and continue to study for better key-management system with it.

This study is a subsequent research results of Lee and Hwang (2015) and presents results of the case in which an information system is developed and applied for the performance management scheme proposed by the early study. This study aims to provide the organizations that want to implement and apply an effective IS operational performance management scheme with the practical alternatives that they may consider. This study first summarize the major contents of the performance management scheme proposed by the early study. Then, the processes and detailed contents in which an information system is developed in order to operate and improve the performance management scheme. The specific contents provided by the study include the system development environments and methods, system architecture, and application structure. Finally, this study summarizes the major results of the study and suggests future research directions.

Recently, roost of the companies have, utilized internet with the purpose of business. According to this tendency, each company is exchanging various information and offering services of e-business through Web-Site. Contents on Web-Site are getting huge and the period of contents renewal is getting short. Consequently, each company is faced with many problems for the contents management because of specialization and fractionation of contents. A contents management system that creates, maintains and manages efficiently and conveniently contents on Web-Site toward solving these problems is very required. in this paper, we design and implement such a web contents management system. It also supports dynamic web page publication based on the XML components.

Effective resource management in the digital library should be implemented for the whole accessible sources on the network including multimedia one such as image files other than texts which focus on books. Contents management can be resource management of digital library in terms of wide scope, moreover, it\`s main function is to provide effectively tailor-made knowledge contents for users\` diversified objective of information usage. In this study, I examined main factors for more effective and advanced knowledge management including web resources under the current digital environment. First of all, I described closely several types of conceptualization and trails regarding more effective contents management and came up with advanced user-centered contents management system, i.e., user factors, intermediary factors, and finally service ones.

Digital contents is used already in near place with us. Contents of MPEG-4 standard is used to process multimedia data in field of communication, computer, broadcasting mobile etc. However, absence of copyright management and protection system and interoperability problem of right system between each corporation happened. Because MPEG establish IPMP(Intellectual Property Management and Protection) system standard in agreement with MPEG-4 system standard, proposed cooperation method to manage and protect copyright. Accordingly, in this paper, put in copyright of authorized contents management and protection extension system implementation adding MPEG-4 IPMP system like plug-in into existing MPEG-4 authorizing tool. Therefore, author edits IPMP information to protect contents or object, and process the information in system and authorize MPEG-4 digital contents that have management and protection sign according to IPMP standard. This system designed and implemented to divided into IPMP information save processor, IPMP information creation processor, media IPPM processor, XMT-A to MP4 converter IPMP extension.

대량의 컨텐츠에 대한 정보 관리 및 잦은 사이트 변화에 따른 퍼블리케이션의 용이성으로 CMS(Contents Management System)의 도입이 많이 이루어지고 있다. 본 논문에서는 CMS의 백앤드와 프론트 엔드를 연결하는 Access Structure 에 관해 고찰해보고, 이를 통해 시스템의 컨텐츠 검색을 효율적으로 지원할 수 있는 방안과 카테고리 수의 무분별한 증가를 막고자 하며, 퍼블리케이션에서의 확장된 아키텍쳐를 지원하기 위한 모델을 제안하고자 한다.
