지하암반층에 처분한 방사성핵종들의 이동방식을 이해하기 위한 방법의 일환으로 다차원 불균일장에대한 모사기법에 대해 다루었다. 이차원 암반균열평면을 설정하고 균열틈 값이 공간적으로 다양한 형태를 가질 때 지하수가 흐르는 유형과 핵종들이 이동하는 특성을 이해하기 위해, 공간적으로 다양하게 변해 가는 균열틈을 가진 암반층을 모사한 다음, 여기서 지하수와 방사성핵종들의 흐름특성을 파악하고 물질이동에 영향을 미치는 중요한 수리학적 매개변수들에 대해 논의하였다. 암반 균열폭 값은 추계적 방식으로 설정한 확률밀도분포와 공간상호간섭길이를 함수로하여 통계적방식으로 계산하였다. 각 매개변수들의 값의 차이에 따라 달라지는 분포상태변화를 그림으로 표현하여 설명하였다.

본 논문에서는 실시간 대화 행위에서 대화 메시지 사이의 응답 관계를 시각적으로 표현하는 방법을 제안한다. 제안한 방법은 기존 텍스트 기반 대화 방식과 트리 기반 대화 방식을 결합한 형태로서 대화 메시지의 일반적인 응답 관계뿐만 아니라, 기존 트리 기반 인터페이스에서 지원이 어려운 최근 수신 대화 메시지의 응답 관계를 시각화함으로써 대화자의 상호작용을 용이하게 한다. 이러한 방법은 기존 텍스트 방식의 테이블 구조에 트리 구조를 결함하여 대화에서 응답 관계를 명확히 구분한다. 제안한 방법의 구현은 XML과 DOM을 이용하여 대화 메시지와 대화 시스템을 구현하였으며, 응용 분야는 협업, 원격 교육, 온라인 게임 등이다.

무선 인터넷 시장의 급속한 성장과 함께 이에 맞는 실용적인 전자지불 방식의 요구가 커지고 있다. 많은 전자지불방식 중에서 전자수표시스템은 계산량이나 정보교환량 측면에서 전자동전방식보다 효율적인 지불수단이다. 그럼에도 불구하고 제한되어 있는 액면가 문제나 지불과정에서 발생하는 거스름의 재사용 문제로 활성화되지 못하고 있다. 이 시스템은 모바일 단말기의 한계에 따른 연산 속도를 고려하였으며, 액면가나 거스름과 같은 문제정올 해결하였다. 부분은닉서명 기법을 이용하여 수표의 액면가의 임의의 표현이 가능하며 거스름의 형태가 처음 발행 받은 수표와 같아 재사용이 가능하게 된다. 이때 거스름으로 재발행 받은 수표는 익명성을 보장하여 어떤 수표의 거스름인지를 알 수 없게 된다.

Hanok is a cultural heritage containing our ancestor's life style intact and breathing alive with us until now. As Hanok has been concerned as a echo-friendly architecture, a new methodology for efficient construction without damaging the traditional construction process comes into request. The goal of this research is development of a architectural design tool based on the BIM(Building Information Modeling) for satisfying these demands. It will be usable to support whole process of the traditional building from digital design to production and construction. Firstly, we take a consideration of the traditional architecture reflecting the spirit of the age and suggest efficient design method for architectural components. Each components is pre-fabricated as a template representing similar components. All pre-fabricated components are designed by object-oriented concepts so, many variations for a component can be derived from the pre-fabricated component. Our method is helpful for reducing design errors because that it considers combining rule between connecting components in the template design. Moreover it is plugged in the commercial architectural CAD, so it can supports digital design not only traditional architecture but also fusion style mixed with modern architecture.

The purpose of this study is to analyse and interpret the way of differentiated expression and changing creative trend following 5-day workweek which has been recently adopted. For this aim 11 pieces of distinctive advertising text were analysed. The criteria for selection of analysing text were relativeness with 5-day workweek and cognitive inconsistency. These texts were negative phrases, exaggerated expression, and excessively humorous appeals. The study revealed the followings: First, 5-day workweek concerned advertising texts were considered as high attention getting and successful in stimulating advertising audiences' curiosity by using the elements opposing the value and belief system formed in the existing audience. Second, consumption-driving lifestyle was found in most expressions for credit cards advertising. Third, hedonic need-oriented lifestyle was typical in young consumer products category. Fourth, family centered lifestyle emphasized meaning of rest and solidarity of family.

The demand of the real-time data was promoted by significant development of network and IT technology. In particular, the entry of an aging society and income growth increase the demand for personal health related data which attempt to provide various and evolutional healthcare services by several healthcare institutions. Especially the presentation of the medical examination result is the most basic healthcare services which should be expressed to maximize understanding in personal health records for their own health. However according to absence of systematic visualization framework and visualization model, intuitive understanding of healthcare related data is difficult. Cosequently In this study, customized visualization representation based on the results of medical examination was provided to aviod consistent format for health examinee and establish a variety of data representations.

Now a day, lots of the animations include TV series Animations are made by the technique of 3D Animation. However, 3D Animation obstructs visual elements and deteriorates an acquaintance with the limit of unfamiliar material methods and dispersion of light. For this reason, a large of number of 3D Animations are repacked with the style of 2D Animation. Most of previous studies for the conversion of output 3D Animation to the style of 2D Animation are analysis for 2D rendering techniques. In case of Non-realistic 3D Character Animation, first and foremost it needs investigation of the basic producing method for the 2D Animation is different with the realistic expression way of the one for the 3D animation. For a case study, expression methods for the non-realistic and the non-actuality 2D Character Animation come with impossible ways in the real life. This study for the 3D Animation with the style of 2D Animation is to investigate on the keynote for effective expression methods, when we turn 3D Animation into the style of 2D Animation.

The contents of remote lectures are written by authoring tools or animation tools. Written contents then integrate existing medias, and are stored in a file type, which is added to the lecturing activities of lecturers. These files are stored according to the kinds of each authoring tool. So, there is no interchangeability and the efficiency of each media is not so good. Due to these structural features, it is not possible to do streaming lectures in on-line environments. In this study, a technique was suggested, which guarantees the interchangeability of remote lecturing contents using SMIL which is a synchronizing multimedia language. The suggested technique is an extended type of SMIL, and includes tags to represent the lectures of tutors which are the specific feature of remote lectures. Additionally, a model, which does streaming SMIL remote lecture contents through on-line, and which transfers control techniques are suggested. The remote lecture contents established by the proposed method can be applied to all authoring tools for remote lectures just by installing conversion modules, and can be a kind of expression model of the synchronizing model for streaming service in on-line environment.

This study explored the simulation of film in the post-modern society through Jean Baudrillard's theory of simulation. The 21st century can be said to be in a simulated world in which representational images dominate and can be said to be the era of images, where reality and imagination cannot be distinguished. In this world, movies are created under the premise of 'fictional' as a work of art created by man, but in the present post-modern society, the audience responds to and ignores the movie according to the expression of this simulation. In this aspect, we looked at the trends according to the expression method of Simulation, and found that successful film works express the cold reality in various and diverse ways and express it with positive 'stimulating' elements. Through this, in order to develop more deeply and systematically in the production of domestic films, various humanistic values, which are double tracks that can systematically compose a simulation that contains a didactic message about the real world and draw the audience's response, It was concluded that an attempt to express 'stimulating' in a positive sense was necessary.

As image contents in broadcasting have been created in HDTVs and monitors have been commercialized, facial expression of objects in broadcasting lighting has become a very significant task. Figure modeling of objects in HDTVs requires smoother and cleaner video images owing to the expansion of precision of image expression by light. Lighting methods that enlighten characters in the digital generation have come to require a new change. Character modeling methods used on expression features of underlight are receiving attention for aesthetic expression of figures in HD images. Accordingly, the influence of underlight light source intensity, distance, and size on character modeling characteristics was experimentally measured and comparatively analyzed. The experiment results show that good results can be obtained only when the intensity is 17%∼25.5% in contrast to total brightness, distance is beyond 40cm, and the size is at least 20cm, to exhibit the optimum effect of underlight. This data will become material with high usage to gain smoother and cleaner images of characters in future high-quality images.
