기존의 전자악보들은 복잡한 인터페이스를 가지고 있어 사용하는데 불편하다는 단점이 있었다. 이에 본 연구에서는 기존의 전자악보 시스템들을 비교 분석하여 보다 전문적인 기능을 가지고 있으면서도 쉽게 사용할 수 있으며, 더 효율적인 연주를 할 수 있는 Two-Panel 구조의 전자악보 시스템의 인터페이스를 설계하였다.

Standards-curriculum based archival contents for education is the best effective teaching and learning units for historical thinking abilities. This paper purposes a developing procedures of an archival contents for education that is theoretical instructions of developing an archival contents for education by the National Archives of Korea. This paper can be used of the theoretical bases for the National Archives of Korea by proposing the methodology of development of an archival contents for education. The developing procedures of an archival contents for education is the same with the procedures of developing an e-learning contents that has planning, analyzing, designing, developing and assessing steps but it is characterized by an archival contents for education that is curriculum standards analysis, collection analysis, and detailed design for structured formats in effective-accomplishments for teaching-learning objectives. I propose the procedures for determining teaching-learning subjects that enable the development of an archival contents for education by curriculum standards analysis. I also propose the procedures for deriving the key words from the teaching-learning subjects. Collection analysis methods analyze key records that correspond to the learning subjects according to the selection criteria of primary sources. In the steps of designing, titles of contents and contents structures have to be determined and storyboards based on flowchart of learning have to be made of according to the results of analyses. In the steps of developing contents, making a copy of primary sources like a original is the key points. And also in the steps of assessment, products of teaching-learning contents to effectively achieve the teaching-learning objectives have to be estimated by the appraisal board. Finally I propose that user's survey research after the services have to be reflected on contents updates and new developments of contents.

In this paper, a touch interface of a smart device using, learner controlled by three-dimensional learning content for more realistic learning environment will be constructed. Fabrication of three-dimensional learning content is difficult. So teachers and learners to create content and share content, a framework was designed. The framework consists of an XML language and intuitive. Android-based devices are available from the playback and authoring. Server environment for content sharing was established. The proposed framework is verified through expert evaluation. In result, it was positively evaluated in terms of usability.

Since passive information users in mass media era became active information producers in this Internet era, an enormous amount of education contents has been created. As people use different production and reproduction tools even for the same content, however, user-created contents (UCC) do not have compatibility among them, which leads to other problems too. In order to solve these problems, this study proposes "a platform in UCC production environment based on standard specification, which will enhance interoperability among contents." We expect that this platform will help design Contents Publication and Management System (CPMS), which minimizes jobs required to be done repetitively for contents up-loading or transfer and thus enables easy contents sharing and management.

Current technologies on digital rights management (DRM) have focused on security and encryption as a means of solving the issue of unauthorized copying, that is, locking the content and limiting its distribution to only purchasers. But, illegal content copy should be protected not only from purchasers but also from other principals such as media distributors and content providers. In this paper, we designed and implemented end-to-end digital lights management system that can cover a content protection on the overall value-chains of content distribution. Proposed system provides content protection and secure management of digital rights in creator, provider, and distributor like in purchaser. Accordingly it can provide an environment protecting each principal's digital rights and prohibiting illegal usage of content.

There are various types of educational contents in mobile world. Moreover new and various kinds of contents have been developed recently according the smart phone has become popular. Therefore, many telecommunication companies of domestic and overseas are showing many kinds of smart phone as to customers are growing more and more interested in mobile devices. Currently, most of the language educational contents are composed to foreign languages like English, Japanese, Chinese, but the development of Korean educational contents are inadequate. In this paper, so, we design the linguistic contents for beginning Koran education of foreigner which are used on mobile platforms.

지상파 DMB 데이터 표준인 MPEG-4 BIFS Core2D@Level1을 이용하여 데이터 콘텐츠 구현 시, BIFS 언어가 갖고 있는 문제점으로 인해 GUI 표현이 어렵다. 따라서 본 논문에서는 이와 같은 문제점을 해결하여 데이터 콘텐츠 개발자가 손쉽게 GUI 기능을 구현할 수 있도록 MPEG-4 BIFS GUI 프로파일을 설계하고 구현하였다. DMB 환경에 적합한 GUI 노드 선정을 위해 콘텐츠 개발자의 요구사항 조사와 타 솔루션과의 비교 분석 및 데이터 콘텐츠에서 자주 쓰이는 기능을 파악하였으며, 이와 같은 분석 내용을 바탕으로 GUI 프로파일을 구성을 위한 노드들을 정의하였다. 각 노드들은 XMT 형식으로 구현되었으며, 정의한 프로파일 검증을 위하여 테스트용 데이터 콘텐츠를 개발하였다. 이와 같은 연구를 통해 DMB 데이터 콘텐츠 개발 시 개발자가 화면 구성에 필요한 GUI를 손쉽게 구현할 수 있게 된다면, 다양한 데이터 콘텐츠 개발을 위한 발판이 되어 향후 데이터 방송 활성화에 기여할 수 있을 것이라 기대된다.

As digital content items increase, new content services are often added to or integrated among existing content management systems to manage them. For efficient system integration, this paper designed a content management system that combines two existing content management systems based on a microservices architecture. In addition, during the development process, integrated system that existing systems were recycled without disruption to existing systems, integrated efficiently and implemented as scalable systems. It measured the resource usage of this systems and analyzed the differences between features for system integration using traditional middleware.
