With the help of information technology The problem of building a concrete form with a shapeless media is the starting point of presenting information by means of sound. Audio-Visual System using sound as a medium is a method that presents an auditory material visually and has a role of linking different sensory organs. In a sense, Audio-Visual System transfers a non-concrete sensation to a concrete one. Audio-Visual System presentation by late methods using active and non-active images produced by computerized irregular procedures can be limited because of the limited ways of visual output. On the other side, visualization using active images can induce more diverse expressions using sound as a medium. This study suggests a new way of expression in animations using visualization of various auditory materials and sounds built by Audio-Visual System with active images.

In 1944 Hans Asperger reported odd bizzare 400 children who showed autism like clinical symptoms but had higher intelligence and relatively intact speech function. He named these child 'autistic psychopathy'. Since them there were many controversial views about this syndrome. Some regards Asperger syndrome as the high functioning autism variant or preschizophrenic childhood condition or childhood form of schizoid personality disorder. Though there were still many controversy, recently ICD-10, DSM-IV accepted Asperger's syndrome as a distinct subtype of pervasive developmental disorder. The authors reviewed the history and conceptual changes of Asperger syndrome and summarized the interesting recent research findings. In addition, the authors argue that this syndrome has some linkage with autism and schizoid personality disorder and proposed that these is disorders do have common defect in social instinctual development.

An accurate system modeling in the underground water analysis requires many accurate parameters on the spot, which have a huge volume, because it may be generated more inaccurate products than to use mathematical analytical solution in a case that a degree of permeation, undercurrent coefficients, boundary conditions, and so on, are inadequately estimated. Recently, handling these parameters easily has been an active area of research. In this paper, we propose a new method which handles these parameters easily and accurately for a system model management using a well-known MODFLOW model. Also, we incorporate this method into ArcView functions. Results of the proposed system incorporated into ArcView are displayed visually.

그동안 사회적 여러 갈등의 갈등 조정을 위한 연구나 기술들은 주로 갈등발생원인들 중 법/제도적이나 정책추진 방법론 등 한 두 가지측면을 고려하여 평면적 분석을 시도하는 것이 대부분이고 특정지역 및 사례에 제한적으로 적용되는 것이 일반적이었다. 이와 같은 갈등 조정의 한계를 극복하기 위해 최근에는 이해당사자의 참여를 유도하고 공학적으로 접근하여 여러 대안 및 시나리오에 대해 모색할 수 있는 공영시각모형이 소개되면서 많은 정책결정과 수자원관리, 수질관리 분야 등에 널리 활용되고 있다. 하지만 객체지향을 내세우고 있는 공영시각모형은 신속한 모의 및 쉽게 모형을 다룰 수가 있다는 장점이 있으나, 공간적인 분석 및 표현은 불가능하다는 단점을 가지고 있다. 이에 본 연구에서는 ArcGIS를 기반으로 HEC-RAS와 연계하여 대상지역의 선 면적 개념의 치수적인 문제점을 도출시켜 이해당사자들에게 인식 및 이해시킬 수 있도록 하였으며, 댐 규모나 다른 대안이 수립되는 경우 이에 따른 수위저감효과와 홍수범람모의 및 홍수피해액 등을 제시할 수 있도록 개발하였다. 모형의 정확성, 신속성 및 다른 지역에서의 적용성 등을 확인하기 위하여 한탄강댐 갈등사례가 있었던 임진강 유역에 적용하여 모의운영 하였다. 그 결과 가상의 여러 대안에 의한 각 결과를 잘 제시하고 있었으며, 댐 건설 갈등현안 중 치수부문에 적용되어 갈등 조정에 기여할 수 있을 것이라고 판단된다.

It is difficult to figure out the specific contents of the buildings in the internet spatial area, since those data on the internet present only the location of buildings and the outlines of lands on which buildings are located, An experimental study for the view management of building information at internet urban spatial area was conducted on the Web-GIS based map using hyper map. With the building information on the 2-D map, modified from the previous numerical map and the regional building information and additional information, a new form of building through 3-D icons was shown on the internet spatial area. This study shows the Web-based building management system, which is designed to manage attribute data about hyper-linked buildings of 2.5-D icons and to reproduce visual building information by putting a variety of information into hyper-linked icons on the hyper map. This system not only complements the lack of consistency between real buildings and those on the map, but also provides users with more familiar urban space, so that everybody can utilize the building information as long as he has access to the internet.

Recently, as the social interest about environmental problems is increased and the importance is highlighted, the related information and the demand of information are increased. and, the Total Pollution System will be executed soon. Therefore, the information management system which can manage and analysis related information efficiently and systematically become required. Especially, the development and application of GIS which can effectively manage and analyze information using spatial data have been processing by government, private institute, and related academic institute of all over the world. also their potentiality of application have been recognizing. The main purpose of this study is to develop the stream water quality management system which can simulate future water quality using water quality model(QUAL2E) and be integrated the whole step from calculating pollutant load divided by administrative district and watershed to displaying the result of modeling visually.

새로운 세기의 수학 교육은 직관과 조작 활동에 바탕을 둔 경험에서 수학적 형식, 관계, 개념, 원리 및 법칙 등을 이해하도록 지도되어야 한다. 즉 학생들의 내면 세계에서 적절한 경험을 통하여 시각적 ${\cdot}$ 직관적으로 수학적 개념을 재구성할 수 있도록 상황과 대상을 제공해야 한다. 이를 위하여 컴퓨터 응용 프로그램을 활용한 자기주도적 수학 개념 형성에 적합한 교수 ${\cdot}$ 학습 모델을 구안하여 보았다. 이는 수학의 필요성과 실용성 인식 및 자기주도적 문제해결력 향상을 위한 상호작용적 매체의 활용이 요구된다. 본 연구는 구성주의적 수학 교수 ${\cdot}$ 학습 이론을 근간으로 대수 ${\cdot}$ 해석 ${\cdot}$ 기하 및 스프레트시트의 상호 연계를 통하여 수학 지식을 재구성할 수 있도록 학습수행지를 제작하여 교사와 학생의 다원적 상호 학습 기회를 제공하는 데 주안점을 두고자 한다.

Conventional visualization of PM (Particulate Matter)10 flows applies superimposition of concentration distribution maps and wind field maps. This method is efficient for small scale maps where only macro flow trends are of interest. However, in the case of urban areas, local flows are difficult to model at micro level using wind fields, and therefore different methods of flow extraction is deemed necessary. In this study, flow information is extracted and visualized directly from the PM10 density data by using the gravity model. This method has the advantage that additional information such as wind field is not necessary for estimating the intensity and direction of PM10 flow. The extracted spatio-temporal flow patterns of PM10 are analyzed with relation to traffic information.

The communication model has been accepted as the basic research paradigm of cartography since Board(1967) discussed the map/model analogy. In that paradigm, the function of maps was limited to the media of communication, and the functionality of maps was extremely emphasized. Therefore the model could not play its own role under the new environments such as computer, GIS, scientific visualization. Nowadays, the model has been attacked on several grounds and several alternatives have been suggested. Among the objections raised are (1) geographic visualization in which maps are considered as the tool of scientific visualization, (2) the contributions of art which are ignored in the positivist cartographic research, and (3) deconstructionist arguments which deny the scientific epistemology of map as an objective form of knowledge and recognize the textuality of maps including their metaphorical and rhetorical nature. Since a publication by McCormick et al, the scientific visualization based on the powerful computer graphics is used in a wide context. Maps are treated as the tools of scientific visualization and emphasis is on exploration of the geographic data to gain understanding and insight in the geographic visualization processes. The research on geographic visualization have stayed in the early stage of developing the conceptual model and the basic visualization tools. But, it is expected that the geographic or visual thinking which is emphasized in the geographic visualization will contribute the reestablishment of links between cartography and geography. Also, the development of scientific visualization tools and strategies will offer the opportunities to suggest a fresh idea, to synthesize information and develop holistic approaches to geographical problems.

인터넷의 활용이 증가됨에 따라 사용자들은 수많은 정보를 주고받게 되었고 이러한 시대의 흐름에 부응하여 네트워크의 대한 지적인 관심도 높아지게 되었다. 그러나 기존의 네트워크 학습체계는 이론적인 개념위주의 평면적인 형태였고 네트워크 자체의 추상적이고 학습 원리와 개념을 경험하기 힘든학습의 특성 때문에 전체적인 학습의 흐름과 기능을 이루는 동작에 초점을 맞추기보다는 각 단위별단편적인 개념위주 내용만 제시하여 전체적인 흐름을 파악하고 학습할 수 있기에는 미흡하였다. 이러한 관점에서 학습 내용이 어려운 네트워크의 동작 원리를 시각적으로 쉽게 이해할 수 있는 학습 도구를 제공하여 학습의 이해와 성취도를 높이는 방법이 필요하다. 따라서 본 논문에서는 학습자가 입체적으로 원리를 파악할 수 있도록 쉽고 흥미로운 학습을 유도할 수 있는 학습 시나리오를 구성하여 학습내용 간 연계성이 있도록 하고 그래픽과 이미지적인 효과를 극대화 할 수 있는 애니메이션을 기반으로 하여 보다 효과적으로 인터넷 동작원리를 학습할 수 있는 학습시스템을 설계 및 구현하였다.
