The focus of this development program is to input multimedia materials into learning according to the trend of recent social changes and to maximize the learning effect for improving problem-solving by offering familiar teaching materials. The expecting effects of this study are as follows: 1. This program helps students acquire mathematical concepts and principles about circular equation through concrete examples using a variety of media - text, voice, sound, and animation and so on - , makes it possible individual learning which was difficult for students to expect at the existing multitude class as progressing learning each unit on the screen and the perfect learning by offering FEED BACK 2. This program varied the difficulty of learning contents to learn according to learning abilities of learners by using animation and making the most of merits of computer and was able to improve learning effect by studying in a mutual way with managing learning procedure nonsuccessively. 3. Class using CAI program about developed circular equation unit has a positive effect on improving problem-solving by becoming from teacher centered class to student centered one. 4. This program makes students understand the contents of auxiliary learning in multimedia computer more efficiently, and cultivate abilities to adopt in accordance with changes in the future society by forming familiar computer mind.

최근 IT분야에서 떠오르는 단어는 모바일 플래시 컨텐츠라고 할 수 있다. 플래시 시장의 장래성에 비추어 볼 때 매우 발전 할 수 있는 분야라고 할 수 있다. 플래시는 캐릭터 다운로드 서비스가 주도해온 모바일 컨텐츠 시장의 선두 자리를 위협하고 있으며, 향후 매우 발전 할 수 있는 분야라고 할 수 있다. 플래시가 주목 받는 것은 많은 사용자들에게 접근할 수 있는 다양한 분야가 많고, 미개척 시장으로 그 가능성이 충분하다는데 있고, 근래들어 국내 모바일 폰이나 상업용 광고에 애니메이션이 주를 이루고 있다. 본 논문은 이러한 점을 감안하여 학생들이 애니메이션을 제작 할 수 있는 플래시 애니메이션 컨텐츠를 제작하고 이것을 응용하여 모바일 게임에 적용 할 수 있는 모델을 설계하고 구현하였다.

로봇디자인은 로봇이라는 첨단기술의 결정체와 인간을 연결하는 인터페이스 역할을 한다. 실용화 로봇기술의 성숙기에 접어들고 있는 현재 로봇에 대한 커다란 시장이 형성될 시점에서는 더욱 로봇디자인이 중요하게 될 것이다. 로봇이 인간과 같은 환경에서 살아가기 위해서는 인간 친화적인 인터페이스 디자인 기술과 기존의 로봇개념과는 다른 상호작용(interaction)을 고려한 로봇디자인이 개발되어져야 한다. 본 연구는 사례 연구 형식으로 쇼핑서비스지원 로봇을 대상으로 필요기능을 도출하고, HRI 디자인 요소에 대한 설계를 전개했다. 그리고 쇼핑서비스지원 로봇 디자인을 전개하였다. 특히, 제스처(Gesture), 표정(Expression), 사운드(Sound)의 HRI 디자인 요소 구성을 쇼핑서비스 로봇에 적용하여 구체적인 결과를 도출하였다. HRI 디자인에 대한 유효성 검증을 위해서 모션캡처, 애니메이션, 뇌파, 사운드 등이 통합된 인간과 로봇과의 구체적인 인터랙션을 제시하였다.

타격감은 슈팅 게임이 가져야할 중요한 요소 중의 하나이다. 게임 개발자들은 시각(특수) 효과, 음향 효과, 진동효과, 애니메이션, 카메라 테크닉 등 다양한 기법을 사용하여 타격감을 높이려 노력해왔다. 이 논문은 이러한 다양한 기법들이 2D 슈팅게임에서 타격감에 어떠한 영향을 미치는지에 대한 실험 결과를 소개하고자 한다. 우리는 사용자를 대상으로 2 가지 실험을 수행하였는데, 첫 번째 실험은 발사체에 적용된 4 가지 효과(시각, 애니메이션(반동), 음향, 진동)에 대한 16 가지 실험 세트로 구성하였고 두 번째 실험은 발사체와 피사체 각각에 시각 효과와 음향 효과만 적용하여 마찬가지로 16 가지 실험 세트로 구성하였다. 실험 결과 모든 개별적인 기법은 모두 유의한 분석 결과를 나타내었으며, 시각 효과와 애니메이션보다는 음향 효과와 진동 효과가 더욱 효과적인 기법이고 발사체 보다는 피사체가 더 중요하다는 것을 알 수 있었다.

This paper describes Web based education technique. We implemented a remote compile system with 8051 micro controller. It implemented the system in this paper so that a learner compiled 8051 control programs to the remote. Most big restriction subject is the control of the hardware in an engineering field even though it implements a remote education system. We download the Java Application to Java Web Start and execute in this system. In this paper the learner controls 8051 executions in Web to the remote and implemented so that we confirmed the action. The supplementary problem will be the construction of a remote education system which offeres existing text and sound information, flash animation.

Multimedia systems present information by various media, for example, video, sound, music, animation, movie, etc., in addition to the text which has long been used for conveying the information. But using several media may cause users' confusion and poorly designed user interface often aggravate the situation. Hypermedia systems allow the retrieval and representation of multimedia information using navigation and browsing mechanisms. Typically, there are two major navigation problems in a hypermedia compared to the ordinary user interface: disorientation and cognitive overload. In this study, the multimedia system was studied from the viewpoint of usability. Practical usability evaluation needs cost-effective, low-skill, and low- investment methods. The 'discount usability engineering' method, one of these methods, is based on the use of the following techniques: scenarios, simplified thinking aloud, and heuristic evaluation. The discount usability engineering method was applied to the usability evaluation of multimedia CD-ROM title.

Multimedia systems present information by using various media, for example, video, sound, music, animation, movie, etc., in addition to the text which has long been used for conveying the information. Among many multimedia applications, the multimedia information retrieval systems commercialized in the form of multimedia encyclopedia CD-ROMs, benefit by using various media for their ability to present information in an efficient and complete way. But using various media may cause end users' confusion and furthermore, poor user-interface design often exacerbates the systems. For appropriate design of the user interface of multimedia information retrieval systems, we investigated the characteristics of the multimedia information retrieval systems and listed 35 variables that might affect the usability of the user interface. And we selected 10 variables through some procedures such as brainstorming, literature survey, expert opinion, relevance analysis and feasibility analysis, in order to perform a screening study which will remarkably reduce the cost and time in conducting subsequent human factors experiments.

Recently, Location-based services(LBS) allow consumers to receive services based on their geographic location data. Users want to take services based location information with portable devices. And Point of Interest(POI) information's usage is increasing with mobile device's development and user's interest. And this paper shows that we connect the multimedia POI database(DB), provide the multimedia services through the portable devices and search POI using location and direction information. The multimedia POI is consisted of sound, image, moving image and animation with location information. When we search POI, we find POI in DB using the area zone and direction information.[l]

Multibody system dynamics is based on classical mechanics and its engineering applications originating from mechanisms, gyroscopes, satellites and robots to biomechanics. Multibody system dynamics is characterized by algorithms or formalisms, respectively, ready for computer implementation. As a result simulation and animation are most convenient. Recent developments in multibody dynamics are identified as elastic or flexible systems, respectively, contact and impact problems, and actively controlled systems. Based on the history and recent activities in multibody dynamics, recursive algorithms are introduced and methods for dynamical analysis are presented. Linear and nonlinear engineering systems are analyzed by matrix methods, nonlinear dynamics approaches and simulation techniques. Applications are shown from low frequency vehicles dynamics including comfort and safety requirements to high frequency structural vibrations generating noise and sound, and from controlled limit cycles of mechanisms to periodic nonlinear oscillations of biped walkers. The fields of application are steadily increasing, in particular as multibody dynamics is considered as the basis of mechatronics.

The infringement of the copyright is a problem by the distribution of digital contents copied illegally. The digital watermark is expected as a thing preventing unjust copying by burying information in digital data such as image, animation, the sound, TV, radio and movies. [1] [2]But a noise is included in a digital watermark reproduction image. So there is the case that the certification of the reproduction image has difficulty with. If a computer cannot recognize the information reproduced from digital watermarking, the information does not have a meaning. This paper aimed at improvement of the proof of a digital-watermarking reproduction image. And it is verified whether the difference of the form of a character affects the degree of correlation.
