  • According to the development of internet with Web, WBI has greatly influence on the present educational society. However, it is difficutly to design the web of the dynamic motions of graphics or animation using general programming technique based on high or low level language. Recently, Mecromedia Company supported a tool that is called Authoware which is the leading visual rich-media authoring solution for creating Web and online learning applications, to solve the problem easily. In the paper, using the the Authoware we tried to develop a web page about tidal variations due to sea level change and intertidal zone variations using the Authorware 5.1. To do this, we used the ocean survey data of Iho beach and the tidal level data based on Tidal Tables of Cheju harbor. The results showed that the Authorware was very useful to construct the simulation of tidal phenomena on web. Therefore, the Authorware can be applied to the simulation related with animation and dynamic motions for the other WBI objective.

  • With the advance of the Internet and computing technologies, e-learning is now a hot issue worldwide for providing the effective learning on the cyber-space. However, most of existing e-learning contents have been developed mainly based on text, including simple multimedia elements such as images, animations, and voices. This paper suggests a method effective for the computer programming e-learning. The method is based on program visualization using flowcharts. It features the stepwise hierarchical program visualization on the level of statements, the flowchart based visualization for control constructs of languages, visualization over whole programs, visualization compared with source codes, and interaction with users. Finally, we implement a system to realize the suggested method, and execute it for an example program.

  • With the growth of the Internet, web-based cyber education is progressing from the text-based to the hyper-based including multimedia, and from one way of simply giving the contents to the learner to another way of providing mutual interaction between the instructor and the learner. For this, there uses the RIA-based dynamic application and multimedia. RIA, which is the new paradigm on the web, provides the learners with more effective and rich contents. For developing a cyber education system, if we use the existing web languages, a large amount of effort is needed. But if we use the RIA-based paradigm, we can remarkably reduce the effort. Also, in developing a new web-based cyber education system the RIA paradigm makes the learners to satisfy their demands, and in developing the system providing the interaction the paradigm gives us the way minimizing the time and effort. In this paper, we compare and evaluate the efforts in developing the RIA based education system with the Non-RIA based education system.

  • In this paper, we present an Example-based Dialogue System for English conversation tutoring. It aims to provide intelligent one-to-one English conversation tutoring instead of old fashioned language education with static multimedia materials. This system can understand poor expressions of students and it enables green hands to engage in a dialogue in spite of their poor linguistic ability, which gives students interesting motivation to learn a foreign language. And this system also has educational functionalities to improve the linguistic ability. To achieve these goals, we have developed a statistical natural language understanding module for understanding poor expressions and an example-based dialogue manager with high domain scalability and several effective tutoring methods.

  • 근래 주목받는 키워드인 유비쿼터스(Ubiquitous), UCC(User Created Contents) 등은 기술적 발달과 함께한 사람들의 행동 양식 변화를 잘 반영하고 있다. 기술적인 측면에서 모바일 환경으로의 진화는 사람들에게 시공간적 제약을 없애주었으며, '호모 루덴스'로 표현된 유희적 인간의 개념은 현대인의 행동 양식을 잘 표현했다. 이중 지상파 이동 멀티미디어 방송(Digital Multimedia Broadcasting, DMB)은 방송에 있어서 시공간적 제약을 없앤 대표적인 사례이며, 'EDUTAINMENT(에듀테인먼트)'는 교육에 유희를 결합한 실례라고 하겠다. 특히 DMB는 정보와 유희의 욕구를 기본적으로 충족시킬 수 있는 방송이라는 매체를 이용한다는 점에서 에듀테인먼트의 기술적 기반이 될 수 있으며, 이를 통해 저 연령의 학습자에게 유희와 교육을 동시에 제공함으로써, 학습효과를 높일 수 있는 장점이 있다. 본 논문에서는 DMB 시스템을 위한 유아 대상의 에듀테인먼트 어플리케이션을 설계하고, 구현한다. 이 어플리케이션을 위해 스토리텔링, 음악과 악기 선택 시스템, 타임라인 및 자유표면 게임 시스템 등 DMB 시스템에 적절하며, 에듀테인먼트의 조건을 충족하는 몇 가지 방법론을 제안하여 방송을 통해 콘텐츠와 대상자가 서로 상호작용 할 수 있도록 한다. 이를 위해서는 기존 방송의 음성, 영상 서비스를 넘어 상호작용의 필수적인 요소라고 할 수 있는 데이터 서비스를 요구하며, 이는 MPEG-4 Part 11: BIFS(Binary Format for Scenes) 기술을 기반으로 그 구현에는 VRML에 기초한 BT(BIFS Text) 언어를 사용한다.

  • Modern society is complex and rapidly changing, and knowledge sharing is needed to acquire and create knowledge. Knowledge sharing is the act of providing information knowledge and know-how of their own in order to cooperate with or help their colleagues. This study presents a research model using social capital theory to explain the mobile knowledge sharing behavior of virtual community members. Based on previous studies, social capital theory is divided into structural, relational, and cognitive aspects. It was composed of social interaction ties as a measure of structural aspect, trust as a measure of cognitive aspect, shared language, shared vision and relational aspect. After collecting survey data, factor analysis and regression analysis were performed using SPSS 22. In this way, we examined how the detailed factors of social capital affect information sharing behavior and how the level of knowledge sharing affects community promotion. The results showed that social interaction ties, shared language, shared vision, and trust affect knowledge sharing. Knowledge sharing has had a positive impact on community promotion.

  • This paper presents a web-based virtual educational system for Java language, which consists of a management system named Java Web Player (JWP) and creative multimedia contents for the lectures of Java language. The JWP is a Java application program free from security problems by the Java Web Start technologies that supports an integrated learning environment including three important learning procedures: Java concept learning process, programming practice process and assessment process. On-line voice presentation and its related texts together with moving images are synchronized for efficiently conveying creative contents to learners. Furthermore, a simple and useful compiler is included in the JWP for providing user-friendly language practice environment enabling such as coding, editing, executing, and debugging Java source files on the Web. Finally, simple multiple choices are given suddenly to the learners while they are studying through the JWP and the test results are displayed on the message box. In order to show the validity of the proposed virtual educational system we analysed and assessed the learners' academic performance on the five quizzes for one semester.

  • The appearance of Intelligent mobile and home appliance increased the using of not only various multimedia contents but also educational contents. Especially the growth of smart device such as smart phone, smart pad and smart TV, provided the environment which everyone can use educational content anytime, anywhere, any device. However many smart devices are hard to reuse the various educational contents because the devices and mobile os policies are not unify. In this paper, we suggest the design of NeS(N-Screen e-learning system) in order to solve this problem. NeS is consisted of User Management, Educational Content Management, Content Convert System and Interactive Management System. In this system, we use the HTML5 language to assure interoperability in various Smart Device Environment. Through NeS, we can achieve Content OSMU(One Source Multi Use) in various device environment and assure the continuity of the contents for using the educational contents more easily.

  • Efficient continuous speech recognition system for practical applications requires that the processing be carried out in real time and high recognition accuracy. In this paper, we study the acoustic models by adopting the PDT-SSS algorithm and the language models by iterative learning so as to improve the speech recognition accuracy. And the adaptive pruning algorithm is applied to the continuous speech. To verify the effectiveness of proposed method, we carried out the continuous speech recognition for the Korean air flight reservation task. Experimental results show that the adopted algorithm has the average 90.9% for continuous speech recognition and the average 90.7% for word recognition accuracy including continuous speech. And in case of adopting the adaptive pruning algorithm to continuous speech, it reduces the recognition time of about 1.2 seconds(15%) without any loss of accuracy. From the result, we proved the effectiveness of the PDT-SSS algorithm and the adaptive pruning algorithm.
