The purpose of this study is twofold: First, to develop new sustainable design methods (aligned with ethnic elements and traditional culture) combined with three-dimensional digital clothing technology throughout the design process, which can be presented as guideline materials for various fashion designs to be developed in contemporary sensibilities. Second, it is the intention to produce creative fashion designs by incorporating the characteristics and methods of Miao's Huangping batik dyeing technique and to present various possibilities in the fashion design field. The overall design characteristics sought by Miao minority are in line with the complex terrain and the ecological and climatic conditions. Miaoist batik dyeing (registered as part of Chinese national intangible cultural heritage) features unique production methods and patterns. The study results are as follows. First, this attempt has enabled understanding of the national costume culture as Chinese Miao's traditional cultural heritage to be promoted, while the direction of contemporary design development using traditional elements has been presented. Second, the study demonstrated new and innovative expressions and styles relying on three-dimensional digital contouring technology and identified the possibility of developing various designs. Third, it was confirmed that the dyed batik pattern design created by the three-dimensional digital contouring technology could be recombined or expanded as digital printing to express the traditional ethnic designs in a practical manner utilizing digital printing techniques based on traditional characteristics.

An in-line phase-shifting digital holographic microscopy system was constructed by inserting a conventional microscope in the object arm of a Mach-Zehnder interferometer. It was used to measure the three dimensional shape of a micro Fresnel lens. It was also shown that both the lateral and the axial resolutions of the in-line phase-shifting system using a self-calibration algorithm were superior to those of the best off-axis system.

최근 컴퓨터 분야의 발달과 사진측량의 발전으로 수치사진측량시스템은 GIS의 기본도 구축, 3차원 지형정보 및 DEM 획득, 수치정사투영영상 생성, 3차원 투시 등 광범위한 분야에 이용됨에 따라 이에 대한 수요가 급증하고 있지만, 이 모든 시스템들은 외국기술에 의존하고 있어서 국내기술개발이 절실하다. 본 연구에서는 수치사진측량기법을 Visual C++ 언어를 이용하여 항공측량용 사진기에 의해 촬영된 한 쌍의 입체사진으로부터 내부표정, Epipolar Line 생성, 탐색영역 설정, 영상정합 등을 이용하여 3차원 좌표를 추출 할 수 있는 PC용 윈도우즈 수치사진측량시스템을 개발하였다. 이 시스템에서는 국가지리정보체계 구축사업의 일환으로 국립지리원에서 제작되고 있는 수치지도를 생성 및 수정할 수 있는 모듈을 개발하였고, 3차원적 입체분석을 위해 여색입체시를 이용하여 모니터상에서 3차원적으로 볼 수 있는 모듈을 개발함으로써 도시의 효율적인 관리를 위한 유용한 기능과 전문적인 수치사진측량시스템을 지원할 수 있는 모듈을 개발하였다.

Transient and asymmetric density distributions have been investigated by three-dimensional digital speckle tomography. Multiple CCD images captured movements of speckles in three angles of view simultaneously because the flows were asymmetric and transient. The speckle movements between no flow and downward butane flow from a circular half opening have been calculated by a cross-correlation tracking method so that those distances can be transferred to deflection angles of laser rays for density gradients. The three-dimensional density fields have been reconstructed from the deflection angles by a real-time multiplicative algebraic reconstruction technique (MART).

Numerical simulation is one of the most useful tools to study gas discharge phenomena that occur in alternating current plasma display panel (AC-PDP) cell. Most PDP cell simulations have been performed for two-dimensional cell, is cross-section along the address electrode. We developed a three-dimensional PDP simulator and applied it to a T-shaped electrode cell in order to show the effects of sustain electrode shape that cannot be included in two-dimensional simulation. The dependence of power consumption on electrode shape and area in the simulation showed the same trend as experiment.

디지털 기술을 이용한 유물의 문양표현 방법은 크게 디지털 탁본기술과 디지털 명암기술의 두 가지가 있다. 디지털 탁본기술은 유물에 새겨진 명문이나 문양을 원형의 훼손 없이 3차원으로 스캐닝하고 이를 객관적 수치로 입체화시켜 명암효과를 표현함으로써 디지털 탁본 데이터를 구축하여 육안으로 확인하기 어려운 원래의 명문이나 문양을 명확하게 나타낼 수 있는 디지털 기술을 말한다. 디지털 명암기술은 유물 표면의 유리질 피막으로 인해서 대상물의 깊이정보를 계산할 수 없는 경우 3차원으로 스캐닝하고 이를 실감이미지 맵핑기술을 응용하여 디지털 명암이미지를 생성하는 디지털 기술을 말한다. 디지털 탁본기술은 주로 토기나 기와 그리고 비석 등 음각 또는 양각으로 표현된 명문이나 문양을 표현하는데 유용하며, 디지털 명암기술은 디지털 탁본기술이 적용될 수 없는 자기나 유리 등의 유물에 효과적으로 이용될 수 있다.

Multimedia boom has happened worldwide these days. In multimedia, we use several kinds of media such as character, figure, voice, music, still images, moving picture etc.. Then I think image including moving picture is the most effective and important media for human being. Creating digital images using a computer has the following two main approaches, depending on how the computer is used. 1. CG Technology. Created images, produced through computer graphics. 2. Digital Image Processing. Images processed through digital image processing technologies. Approach (1) is very popular as Computer Graphics. Two-dimensional and three-dimensional computer graphics techniques are used over wide applications today. On the other hand, Approach (2), which uses digital image processing technology, has been attracting attention lately, in the filed of movies and television. In this report, I will introduce these approaches of CG and digital image processing, and show some application fields such as current movies.

Digital media was realized by two-dimensional design backup. But, digital medium decides form of architecture, and act as a design tool that can expand area of thinking. With such social change, investigate for digital architecture. And, wish to analyze design process of digital architecture and search the characteristics. Through comparison of digital and analogue, clear up that the digital world had complex and ambivalent attribute. Define digital design process as "Digital continuum" with characteristic of digital architecture and divided in 3-steps of concept - development - representation. Analyzed digital design process of Frank O, Ghery, Peter Eisenman and Greg Lynn on th assumption division. As a result, design concept is starting from three-dimensional thinking instead of existent two-dimensional thinking. And because general work of process was gone by digital media, "mass costomization" was possible. Also, it gave architect new role. Differ with former days, select various variables, should tuning and cording, and emphasize role as coordinator who must select the result. Digital is summoning very radical and epoch-making change in architecture. At center of these change, digital design process asks architect complex thinking and creative concept.

문화유산 분야에서 일찍이 문화유산을 보존 복원하기 위한 목적으로, 3차원(3D) 디지털 기술을 이용하여 문화유산의 원형을 기록하여 왔다. 하지만 문화유산 3차원(3D) 디지털 기록은 점군 데이터 취득부터 3차원(3D) 모델 제작까지 복잡한 단계를 거쳐 생산되는 대용량의 디지털 기록으로, 장기 보존 문제를 피할 수 없다. 국제적으로 관련 논의가 활발히 진행 중에 있으며, 국내외 선행연구와 사례 분석을 바탕으로 문화유산 3차원(3D) 디지털 기록의 보존 방향을 제언하고자 한다.
