In this study a framework for cost effective visualization application is presented. Visualizations of a complex street rehabilitation and a highway interchange project are performed. The visualized products were presented to political and community groups, which significantly expedited the consensus building and project approval process.

This paper briefly introduces the work done up to 1998 during the past twenty years for numerical modeling of ocean process focussing on the neighbouring seas of Korean Peninsula. Modeling of global ocean dynamics has also been performed as a pathway to understand the regional ocean dynamics. The ocean simulation produces a vast amount of multidimensional multivariate dataset therefore adoption of scientific and technical visualization techniques were essential to properly understand the physics involved.

In computer forensics investigation, the investigators collect, protect, analyze and interpret massive amount of data which were used in cyber crime. However, due to its huge amount of information, it takes a great deal of time and errors often result even when they use forensics investigation tool in the process. The information visualization techniques will greatly help to improve the information processing ability of human when they deal with the overwhelming amount of data and have to find out significant information in it. The importance of Intrusion Detection System(IDS) among network forensics is being emphasized in computer forensics. In this study, we apply the information visualization techniques which are proposed to be a great help to IDS and carry out the usability test to find out the most effective information visualization techniques for IDS.

In this paper development of on-line data visualization program is described and some examples of data postprocessing are shown. The program is written in JAVA language and runs as a JAVA applet on the web browser such as Internet Explorer or Firefox. Remote users can use the program to visualize and analyze their own flow data by accessing the program server through the internet and loading data files in proper formats from their local computers. This paper describes briefly about algorithms for data visualization, structure and available functions of the program, and web sever system. The mechanism of how the JAVA applet can access and process local data files and relevant coding techniques are explained as well. Also explained is what is required for the remote users and client computers to access the program on-line. Some visualization examples performed on a local computer are illustrated by accessing the server remotely.

The real-time holographic interferometer with digital high-speed camera is applied to the experimental study of laser induced plasma/plume in pulsed Nd:YAG laser welding. A pulsed Nd:YAG laser with 1.2 kW average power is applied to generate laser induced plume. The recording speed of the high-speed camera is 3,000 f/s. The high speed photographs of weld plume without another visualization method, are compared with the visualization photographs with holographic interferometer. The radiation intensity from the laser induced plume is recorded by the high speed photographs, which fluctuated during laser radiation and disappeared after laser end. The density distribution of the plume is recorded by the holographic visualization method. The experimental results show the process of generation of the laser induced plasma/plume, and give the feasibility of quantitative measurement of laser induced plume in laser welding.

본 연구는 지방 문화재 특성화 사업의 일환으로 안동지방 전통문화재인 하회마을 ' 하회별신굿' 탈의 캐릭터사업계획에 따른 시각화 작업을 안동 MBC방송국으로부터 의뢰 받고 1998년 6월 1일부터 8월 20일 까지 약 3개월간의 작업과정과 작업결과에 대한 것을 기술한 것이다. 또한 본 논문에는 작업과정 중 기초적인 예비 조사단계에서 자료수집 및 분석과정과 본격적인 아트워크과정, 그리고 최종적인 시각형태를 수록하였고, 향후 각 지방자치단체에서 본 프로젝트와 유사한 전통문화재 캐릭터사업의 시각화작업을 중심으로 그 문제점과 고려해야할 사항들을 요약해서 결론으로 했다.

A flow visualization technique was developed to analyze flow distribution inside a dishwasher in this study. Then, a new design plan was proposed to improve the efficiency of the dishwasher by the analyzed results and it was confirmed experimentally by the developed technique. Gas flow fields inside a drying duct of a tub for a drying process was investigated by a developed PIV (Particle Image Velocimetry) and a CFD (Computational Fluid Dynamics) method. Also, the flow visualization technique was developed for the liquid flow field of a rotor-arm system to propose the improved design idea. Also, interactions between liquid and gas were observed around the rotor-arm system. The two-phase flow was modified to the liquid flow field because laser sheets are refracted when pass through the two-phase flow. Thus, the flow visualization techniques was developed in this study to measure the instantaneous flow velocities in the liquid quantitatively.

기존의 다양한 데이터 시각화 툴에서 제공하는 차트 추천 방식은 사용자의 의도를 고려하지 않은 상태로 차트를 추천한다. 일부 시각화 툴에서는 세분화된 정량적 데이터 분류 체계를 따르지 않기 때문에 명확한 데이터 시각화가 이루어지지 않고 있다. 본 논문에서는 입력된 정량적 데이터를 정확하게 분류하고, 사용자 의도를 반영하여 효율적으로 차트를 추천하는 가이드라인을 제안한다. 가이드라인은 데이터를 분석하는 분석 가이드라인과, 입력된 데이터 타입과 사용자의 의도를 반영하여 차트를 추천하는 추천 가이드라인으로 구성되어 있다. 이러한 가이드라인을 통해 차트 선택 과정에서 사용자의 의도에 부합하지 않는 차트를 배제하였고, 사용자가 차트를 선택하는데 소요되는 시간이 감소하였음을 확인하였다.
