This study aims to investigate the effects of problem-solving competency of students when they study with digital textbook contents and digital inking in collaborative learning. The experimental group solved the math problems using basic digital textbook contents and digital inking while the control group solved the math problems using basic digital textbook contents alone. The result of analysis and comparison is as follows, the experimental group with basic digital textbook contents and digital inking showed more improved problem-solving competency than that of the control group with basic digital textbook contents alone, the experimental group showed recorded a higher satisfactory level than that of the control group.

Beyond the digital world from the analog age, the contents are very easily copied under the illegal conditions and these are rapidly distributed by the information super highway. The increase of ilegal usage and conflict in digital content market would diminish motivation of creators for their work, furthermore break down digital content market on cyberspace. Watermarking technology support to the legal users by the protection technique based chi the digital content copyright protection method(DRM). Most of previous digital watermarking have embeded to the content. In this paper, we have researched the standardization of digital rights management and developed more efficient watermark embedding method.

The best value proposition for the customers of satellite-DMB (hereinafter referred to as the "S-DMB") business in an environment of fierce competition shall be securing the best killer contents and distribute them in reasonable price as a mobile contents platform provider. In an era of merging the broadcasting with the communication, although many new players tapping into the market with state-of-the-art media such as digital convergence, the key to success in the market is dependent on whether the respective digital contents providers retain competitive digital contents which suit the taste of customers. Considering such market conditions, the purpose of this study is to look over the management examples of Korean S-DMB providers which is carrying out business in digital multi-media market and opening up the market, and to analyze the management strategies of domestic S-DMB companies to be the champion in the market.

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 devices for the digital home in ubiquitous environment aim at providing multimedia services which are not limited to the time and space. However, it does not ensure the fair use of digital contents and causes damage to the contents providers because of indiscriminate distribution of digital contents and the use of illegal contents. DRM system for solving this problems cannot protect the license stored on digital home devices and manage license by redistribution of contents. In this paper, digital forensic model that enables the misuse detection and previous interception of large-scale illegal distribution for contents and license, and also enables the creation and management of digital evidence for legal countermeasure.

This study has began to develop a method for the student major in visual communication and media design to allow them approach to digital contents design developing process in easier and more effective way. The aim of this study is to investigate the potential significance of developing analogue contents design as one of the preliminary works in the digital contents design developing process. The results revealed that designing analogue contents as one of the preliminary works of the digital contents design is: Firstly, it reduces students' mental pressure in organizing the structure of overall information clusters at the phase of information architecture. Secondly, it helps students to find out the object and the preferable form of information design intuitively in the process of information design. Lastly, it is helpful for students to understand the characteristics of digital contents design through clarifying the differences between analogue contents design and digital contents design.

The change of digital convergence service environment converted the subject of design into user -centric one instead of developer-centric one, and changed the existing design environment focused on product development into the new user -centric design environment. Accordingly, GUI considering user's usability come to take big shares in those contents being used for multimedia equipments. However, as the present educational contents provide complex interface due to its design produced based on the existing e-learning system, they have many problems in that they don't consider user's usability. Thus this paper aimed to analyze actual examples through GUI elements of educational contents being used for multimedia equipments and attempt to suggest some directions for development. additionally, consider the various characteristics of digital convergence environment and educational contents, and try to set up strategic directions possible to utilize user'-centric interface elements more usefully and properly at the time to produce designs.

Channel of distribution of contents of digitalised multimedia contents is changing in form passed directly to consumer from manufacturer through digital network of high speed. Together, diffusion of various digital equipment that do is changing Past multimedia consumption structure with the wonderful speed so that can consume easily digital contents. Specially, Multimedia Personal Computer and fast diffusion of a digital television are acting role such as catalyst that promote easy purchase and consumption of multimedia contents of good qualify. However, this system is no method that can sell digital contents and express right that original owner for the contents can insist nothing but consume. Because consumer can distribute to another person copying contents that buy because of and user can distribute producing ashes again according to necessary field by oneself as well as, can lose meaning for original contents. In this paper, Text editing system for XrML (extensible Rights Markup Language) that describe about integrity of message and entity authentication in addition to necessary rights, fees, condition etc. and this to do fetters XML (eXtensible Markup Language) for copyright protection for digital contents in treatise that see hereupon and use digital contents design and embody.
