Samguk Yusa is a important historic record about the dynasties of ancient Korea. It consists of information about the hidden, mythical history, old languages and poems. This historical book has been translated many times since the Liberation of Korea in 1945. However, these books are the result of academic research so we are restricted in our usage of them to understand Korean history. There are many historical documentaries and TV series on Samguk Yusa. However, these programs can be viewed only and not be utilized in any way by the audience. Since the computer was introduced to the public, multimedia technology has been a good source to combine text, image, moving picture, sound, animation and graphic. Producing the CD-ROM about historical books not only produce digital images but also a valuable high quality digital information. Digitalization process also keeps the original content of the historical books as well as provide value as a research material as historical, artistic and archaeological item. Furthermore, its information would be provided through a network, like internet, to share and to promote more advanced studies. The purpose of this study is to produce the basic method of multimedia design of Samguk Yusa. This study also researches the problems of multimedia process for more effective usage.

Carlo H. Sequin, a computer scientist, became to know a sculpture of subtle space construction which was created by Brent Collins, a sculptor, and introduced it as 'Visual Mathematics' in a journal. Sequin who was able to deduce a basic logic of the construction, has developed a software which can be used for virtual modeling merely by substituting simple numerical values using a computer and supplied it to Collins. The present author who was exposed to their collaboration works through series of their papers published in the journal, Leonardo, introduces the Collins' sculptures and the author's modeling procedures of animation works both of which show many common things in visual characteristics and modeling expansion method. The author investigates the mathematical characteristics which is used as a basic motive of modeling and then supplied as a principal visual characteristics of a material. 'Modeling Development by Principle Expansion,' in which the expansion is developed on the base of space twist as for Collins whereas the space section as for the present author, is introduced in this study. With the same stream of the mutual reaction in 'arts, sciences and technology' which has been stressed with the development of sciences and technology, this modeling technology is suggested as a research theme which has a possiblity of various applications.

When various kinds of contents are developed in accordance with higher rate of Internet use to have quality conditions, added values can be elevated in genuinely strong power of Internet. As soon as visiting web site on Internet, men are invited to visit corresponding information web site by a variety of techniques and colors. The visual expression is thought to be important, and color plans of web designs play an important role. This is because the color decides on images of web design to transfer sense as an important element. The paper selected colors by each type of web site and investigated color images. The purpose of the paper is to classify local web sites by each type, for instance, identity, information/community, entertainment, shopping and learning, etc and to suggest directions of color image plan by each type of web site.

We all know *.x file is a bridge of the 3D model developer and the game developer. In today's 3D game programming, more and more advanced hardware support it to run, but we still need to consider the methods to generate the animations. 3D model maker is tired of rectifying the skeletal animations. If he mistakes one point in some one animation, this will lead to distortion in *.x file. Then the modification consumes long time. So finding a good blending method is the best choice for generating multiple skeletal animations. There were some methods for animations blending. In this paper, we could use 3D max or Maya to blend animations; and we could use *.x file and blend animations in coding. And we will use 3D max 8.0 to export the *.x file and present a better way to combine skeletal animations.

<2010 만화산업백서>에서는 2009년과 2010년 상반기 주요 이슈 중 하나로 학습만화의 강세를 꼽았다. 시리즈(예림당)는 3천만 부를 돌파했고, <만화로 보는 그리스로마신화>(가나출판사)는 2천 3백만 부를, <먼나라 이웃나라>(김영사)는 1천 5백만 부, <마법천자문>(아울북)은 1천3백만 부, <코믹 메이플 스토리>(서울문화사)는 1천 1백만 부, <서바이벌 만화 과학상식>시리즈(아이세움)는 1천 만부를 각각 돌파했다고 한다. 초판 발행 부수가 2,000부도 넘지 못하고 있는 현 만화 단행본 시장에서 이러한 학습만화의 강세는 단순한 유행이나 교육열을 넘어, 학습만화가 한국 만화 산업에 중요한 위치로 자리매김 했음을 보여주고 있다. 실제로 2009년 출판만화 시장의 현황을 보면, 어린이만화는 총 927종이 발행되어 시장 규모가 2,362억 원에 달해, 출판만화 전체 시장의 67%를 차지하고 있을 정도로, 한국 만화 산업에서 중요한 위치를 점하고 있다.1) 1970년대 '만화전집' 형태로 출판되어 영업사원들에 의해 판매되던 한국 학습만화는 1987년 고려원에서 출간된 이원복의 <먼나라 이웃나라>에 이르러 대중들에게 주목받기 시작했다. 그러던 것이 2000년 초반 <만화로 보는 그리스로마신화>와 <서바이벌 만화 과학상식>시리즈와 <마법 천자문> 등이 참신한 기획력과 적극적인 마케팅 전략으로 천만 부 시대를 열었고, 시리즈에 이르러 3천 만부를 돌파하면서, 명실상부 학습만화 시대를 열었다. 물론 2000년대 중반 인기작의 아류작들이 쏟아져 나오고, 만화 출판 경험이 없는 출판사들이 학습만화 시장에 뛰어 들면서 학습만화 시장의 거품에 대한 우려의 목소리가 아주 없었던 것은 아니다. 실제로 학습만화 시장에 뛰어 들었던 많은 출판사들이 서점 가판대에 제대로 진열조차 못해본 체 사라져 가고 있다. 그럼에도 불구하고, 학습만화 시장은 꾸준한 성장세를 보이고 있다. 그렇다면, 천만 부 이상을 판매하고 있는 학습만화의 성공요인은 무엇일까? 본고에서는 성공한 학습만화의 스토리텔링을 유형별로 분류하여 분석해 보고, 변화한 스토리텔링 방식이 마케팅과 기획력과 결합해 어떻게 시너지 효과를 내고 있는지 사례별로 분석해 보고자 한다.

We propose a Web-based collaborative CAD system which is independent from any platforms, and develop a 3D solid modeler in the system. We developed a new prototype of 3D solid modeler based on the web using Java 3D API, which could be executed without any 3D graphics software and worked collaboratively interacting with each user. The modeler can create primitive objects and get various 3D objects by using loader. The interactive control is available to manipulate-objects such as picking, translating, rotating, zooming. Users connect to this solid modeler and they can create 3D objects and modify them as they want. When this solid modeler is imported to collaborative design system, it will be proved its real worth in today's CAD system. Moreover, if we improve this solid modeler adding to the 3D graphic features such as rendering and animation, it will be able to support more detail design and effect view.

Recently, due to the development of attack techniques that can circumvent existing information protection systems, continuous threats in a form unrecognized by the user have threatened information assets. Therefore, it is necessary to support the prompt responses to anticipated attempts of APT attacks, bypass access attacks, and encryption packet attacks, which the existing systems have difficulty defending against through a single response, and to continuously monitor information protection systems with a defense strategy based on Indicators of Attack (IOA). In this paper, I suggest a centralized intelligent information protection system to support the intelligent response to a violation by discerning important assets through prevention control in a performance impact assessment about information properties in order to block the attack routes of APT; establishing information control policies through weakness/risk analyses in order to remove the risks in advance; establishing detection control by restricting interior/exterior bypass networks to server access and monitoring encrypted communications; and lastly, performing related corrective control through backup/restoration.

In 3D animation most people adjust the moving motion of their characters on various terrains by using motion data acquired with the motion capture equipment. The motion data can be used to present real human motions naturally, but the data must be captured again to apply to the different terrains from those given at acquiring mode. In addition, there would be a difficulty when applying the data to other characters, in that case the motion data must be captured newly or the existing motion data must be heavily edited manually. In this paper we propose a unified method to generate human motions of walking and running for various terrains such as flat plane, inclined plane, stairway and irregular face. With these methods we are able to generate human motions controlled by the parameters : body height, moving speed, stride, etc. In the proposed methods, the positions and angles of joint can be calculated by using inverse kinematics, and we calculate the trajectory of the swing leg and pelvis according to the cubic spline. With these methods we were presented moving motions using a model of a human body.

Delivery efficiency of e-learning media can be influenced by authoring processes. Generally, a moving picture recorded by video camera can be delivered to student by multimedia streaming service, using media server technology. A e-learning media authored by lecture authoring tool is played in a student application by download-based delivery system. Recently, some animation know-how are applied to author e-learning media by hand-operation. In this paper, we suggest a client-based streaming service for the e-leaning media consists of media files and integration data The lecture of e-learning media nay be divided into some time-based small blocks. Each blocks can be located distributed site. The student system gather those blocks by download-scheduling. This is a valid method for QoS guarantee streaming services. In addition to our study, lecturers can author composite e-learning media includes media files and dynamic web pages simply, The distributed e-learning media files of our study is managed by multi-author and updated rapidly.

Micro-simulation models have been recognized as an efficient assessment tool in developing traffic signal control technologies. In this paper a prototype of a microscopic simulation model which can be applied to evaluate the performance of traffic-adaptive signal control strategies was developed. In the simulation process, space-based arrays were appled to estimate parameters of car following and lane changing models. Two levels of link types, a micro-type and macro-type links, were also embodied in the simulation process. The proposed model was tested on a test network consists of 9 intersections. The performance of the proposed model was evaluated in link by link comparisons with the results of NETSIM. The results show that the proposed model could appropriately simulate traffic flows of the test network. The model also produces traffic adaptive signal timings, cycle lengths and green times for turning movements, based on the detector data. It implies that the optimization process of the model produces reasonable signal timings for the test network on the cycle basis.
