디지털 방송 기술의 비약적인 발전은 그 수요와 공급을 늘려가며 디지털 컨버전스 시대의 매력적인 산업으로 디지털 방송을 급부상시키고 있다. 이러한 발전 추세를 반영하듯 국내 아날로그 방송 서비스는 2012년을 기점으로 종료해야 하는 운명을 맞아 그 가속화는 더욱 빨라질 것으로 예상된다. 한편, 디지털 방송의 한 분야인 지상파 이동 멀티미디어 방송(Digital Multimedia Broadcasting, DMB) 역시 시류에 발맞추어 디지털 방송과 모바일 환경의 결합이라는 추가적인 이점을 안고, 몇 가지 서비스를 선보이고 있다. 하지만 이와 같은 이점에도 불구하고, DMB 서비스는 교육 혹은 광고 분야 등의 뚜렷한 수요의 증가를 가져오는 콘텐츠에 대한 제작과 배포가 쉽지 않고, 그 방법과 기준이 혼재하는 어려움으로 인하여 DMB가 지닌 무한한 가능성에 비해 크게 이슈화가 되지 못하고 있는 실정이다. 본 연구에서는 이러한 점에 착안하여, 지난 연구들에서 얻은 경험을 밑거름 삼아 기본적인 콘텐츠의 제작 및 배포는 물론 DMB 서비스에서 특화될 수 있는 콘텐츠를 더욱 쉴게 생성할 수 있으며, 기술적으로는 3차원 객체를 지원하는 부분을 보강하며, 편리한 인터페이스 등을 포함하는 저작 도구를 개발한다. 이를 위해 기존 연구들에서 다루어온 MPEG-4 Part 11 : BIFS(Binary Format for Scenes)를 기반으로 국내외에서 연구된 기존의 저작도구들을 비교하며, 새로운 아이디어들을 접목시켜 향후 DMB 서비스에서 효율적으로 쓰여 질 수 있는 저작도구를 개발한다.

Edutainment refers to the form of entertainment designed to educate as well as to amuse. It typically seeks to instruct its audience by embedding messages or educational contents in some familiar form of entertainment such as computer games, films, websites, multimedia software, etc. The purpose of this study is to identify the determinants of attitude toward online game-based edutainment. This study proposes the attitude, fun, usefulness, social interaction, challenge, and educational story as major research variables, and collected the survey responses from game players having experiences with online game-based edutainment. Factor analysis confirmed that 19 questions can be categorized into 6 factors : attitude, fun, usefulness, social interaction, challenge, and educational story. Regression analysis shows that fun, usefulness and educational story significantly and directly affect the attitude toward these edutainment games, and that educational story influences the level of usefulness. In addition, challenge and social interaction were found to have significant impact on fun. In conclusion, the wider implications of the findings for utilizing online game-based edutainment are provided.

This paper deals with the design of teaching learning model for programming language education. Various courses related to programming language education have opened at the university having many academic majors. In the meantime, a variety of programming languages have been developed, many integrated development environments of programming language have also been developed for users to make a program easily. But it is difficult for many novice learners to learn programming language still, likewise it is difficult for many teachers to teach the introduction course of programming language. In this paper, we have designed a teaching learning model based on scholastic achievements and blended learning for programming language education. The teaching learning model designed in this study was applied to a course opened in the second semester of 2011. According to the course evaluation result, the teaching learning model for programming language has shown to be an effective for novice learner.

In this paper, we propose a Scorm-based Sequencing & Navigation Model for Collaborative Learning. It is an e-Learning process control model that is used to efficiently and graphically defining Scorm's content aggregation model and its sequencing prerequistites through a formal approach. To define a process based model uses the expanded ICN(Information Control Net) model. which is called SCOSNCN(SCO Sequencing & Navigation Control Net). We strongly believe that the process-driven model delivers a way of much more convenient content aggregating work and system, in terms of not only defining the intended sequence and ordering of learning activities, but also building the runtime environment for sequencing and navigation of learning activities and experiences.

In this paper, we propose a novel model and effective authoring strategy of educational contents which improve the drilling effects in the cyber education through Internet. Especially we offer an authoring process of digital contents of engineering departs using JAVA component library technology and concept-based branch method, making the element of the library as unit-contents separated in accordance with their characteristics arid then accessing them at arbitrary instant in the replaying time. In proportion to the proposed model and strategy, the resultant contents shows advanced adaptabilities and interactions so that the contents can be user-oriented considerations. Combining and realizing the proposed authoring strategy for constitution of digital contents, we can get a more efficient scenario of making and drilling especially in the area of engineering or language courses.

The Korea government has recently announced "A Master Plan for Smart Education", including application of digital textbooks and composition of education system using cloud computing. Our education system in future circumstance, over the conventional e-learning methods, needs the smart education solutions which enable students to study and communicate on various types of devices. The ongoing government project related with the digital textbook has been performed as mid- and long-term goals, whereas PDF-based e-textbook project, similar to e-book model and, has been already completed for the short-term goal. For the purpose of improved future smart education circumstance, however, a specific strategy is required in the following areas: flexibility of format conversion and independency of original text sources among the multiple device platforms. Therefore, in this paper, we propose a standardization scheme for e-textbook format based on e-book structure. To do this, we survey trends in e-book technologies, and research on standardization of e-book format for digitalization of textbooks, based on the analysis of existing textbooks. Moreover, we produce an example e-book content using our proposed standard method. As a result, our approach can be applied to the future smart education circumstance, and we may say that it will be efficiently applicable to the long-term digital textbook project.

The digital app-book is an advanced form of the electronic book (e-book), which attracts a lot of interests by the help of video, sound, sensors and a variety of interactions. As mobile devices have evolved, the demand of digital app-books is also rising substantially. However, the distribution of digital app-book contents is hard to meet the demand because the digital app-book requires a lot of programming cost for the interaction. To resolve this problem, Was verified and implementation as a library function of the interaction between device and user. The proposed library consists of three parts (user action recognition, device action, and content action) and provides various user-device interaction functions by combining methods of each part, which can support source code reusability, easy understanding and availability, and wide expandibility. The library was used in the development of natural science education app-book contents. As a result, it could reduce a lot of code lines and facilitate more rapid app-book development.

One of the major issues in the field of corporate training and formal education is the support of personalized learning. Successful personalized learning needs the availability of the relevant learning contents at just-in-time for learners each. The competency is one of personal characteristics. So competency-based learning is one of the methods that fulfill the above need. Successful competency-based learning needs the method that recommends the relevant contents for the user's deficient competency based on the user's current competency and objectives. We assume that there exists a student information system that provides each user's competences and objectives as fields of a LIP/ePortfolio-compliant student information. This paper proposes an ontology-based system that, given the user's competences and objectives from the above student informaton system, recommends the relevant contents among a large number of educational contents using competency ontology and domain ontology. The advantage of this system can easily handle the change of competency map and terms related with competences in student information and education contents.
