The purpose of this study is to examine the expressional characteristics of T-shirts design using digital printing. Through digital printing system, a variety of patterns and pictures can be printed on T-shirts in a relatively short time. At this backdrop, the result of this research can aid to develop design of T-shirts with a high value added on it. The result was that the printing methods were categorized into borrowing the pictures of masterpieces, applying photography or caricatures, introducing graffiti or lettering, and representing industrial arts. In conclusion, digital printing system unlike the established printing method can have almost an unlimited range of expressing various kinds of pictures and patterns, so that designers may develop high value-added differentiated T-shirts. In other words, by creating a variety of designs with no limit of its quantity, its expressive range can be more widened and with an increased development of plotting machines, we may manufacture more varied kinds of products in a small quantity at a faster rate.

This study shows that digital technology is adapted practical method in fashion design process and virtual simulation and cyber fashion gallery based on virtual reality are researched. This study is proposed the 3D fashion design simulation in the virtual space used on 3D studio max, poser, photoshop program according to fashion design process. The main design concept is "temporary bridge" from rainbow. This study is supposed six fashion design in accordance with three sub-theme under main concept by changing color and texture used on 3D simulation. The results of this study are as follows: 1. This study produced Cyber Fashion Gallery in virtual space to the form of CD Rom title and web title by Macromedia Director 8.5, Macromedia Flash, Sound Forge. And it is enlarged the field of expression in aspect of Fashion Exhibition, beyond restriction of time and space. 2. Clothes modelling tools is able to easily adapt to various textiles and patterns in 3D dynamic virtual mannequin before making clothes. Digital technology is able to express image changed color and texture, especially new material, multi-finishing material and brilliant material and so on. So this study is able to develop tools for study of fashion coordination. 3. Cyber Fashion Gallery consists of gallery, story, painting, symbolism, example, image, quit. This study is enlarged the range of clothing expression by digital technology and open to possibility customized-manufacture.

By classifying temporary denture production for surgical guides, digital guide-based surgery, and final prosthesis production, the problems of each process were assessed in advance and the factors that could be improved were confirmed in this study. The manufacturing process of fusion dental prosthesis uses virtual programs and computed tomography images to manufacture devices using the latest technologies of computer-aided design/computer-aided manufacturing and three-dimensional printing, which enables implants to be placed in the desired location in advance. Moreover, implant placement is not dependent on the skill and condition of the dentist, and because it uses a computer system, it can always be performed at a constant and optimal position. This can reduce the remanufacturing rate compared with the general method, shorten the treatment period, and eliminate patient discomfort. Unlike the traditional method of using impression materials and plaster models, digital fusion dental prostheses would be evaluated as a technology for producing prosthesis through professional design technology and communication.

구강 스캐너를 이용한 디지털 인상과 CAD-CAM (Computer-aided design-computeraided manufacturing) 기술은 점차 발전하고 있다. 전통적인 인상 채득, 작업모형의 제작, 왁스 납형 제작 및 주조의 복잡한 과정이 단축되었으며 환자의 방문 횟수도 줄일 수 있게 되었다. 구강 스캐너 기술의 발전으로 디지털 인상의 정밀도와 정확성이 향상되었으며, 그 적응증은 보다 광범위한 부위의 고정성 치과보철물의 수복으로 점차 확대되어지고 있다. 본 증례 보고에서는 광범위한 부위의 고정성 임플란트 보철물의 수복을 위하여, 컴퓨터로 계획하고 가이드 수술용 템플레이트로 완전히 가이드된 수술을 하고, 즉시/조기 임플란트 보철물을 장착하였으며, 임시 보철물에서 최종 보철물로 전환하는 과정에서 구강스캐너의 지대주중첩 알고리즘을 활용하였다. 임플란트 수술 당일 획득한 구강스캔으로 맞춤형 지대주를 포함한 임시 보철물을 제작하여 활용하였으며, 최종 보철물은 임시 보철물에서의 맞춤형 지대주를 낀 채로 구강스캔하여 제작되었다. 이 과정에서 임시 보철물 장착 전에 미리 스캔해서 라이브러리화한 맞춤형 지대주 데이터를 구강스캐너 소프트웨어 '지대주 자동중첩 기능'으로 최종 디지털 인상에 자동적으로 매칭하였고, 치은연하마진인 부분도 지대주를 탈거하지 않고, 치은압배사 없이 정밀하게 획득할 수 있었다. 구강스캐너와 소프트웨어의 다양한 기술을 응용하여 임플란트 치료 과정을 디지털 워크플로우로 변화시킴으로써, 환자 불편감 및 치료 시간을 단축하였으며, 환자와 술자에게 모두 이롭고 예지성 있는 치료가 가능하였다.

Recently, the industry actively adopts the cutting-edge technologies of the fourth industrial revolution and uses them to enhance the productivity and service of mass-customization. The manufacturing industry is creating new processes and business models by achieving digital transformations through a lean start-up approach aimed at achieving the highest customer satisfaction with minimal resources. Although attempts are made to manufacture the building by introducing the latest technology in architecture, it is applied sporadically, not as an integrated system, in the entire phase of the architectural project. This paper analyzes the changes in the construction industry through the application of core technologies of the fourth industrial revolution. Design processes are analyzed for the digital transformation of the construction industry by case study of advanced architectural design practice. A novel design concept model 'Architectural lean startup' is proposed by combining the architectural process and the lean start up method. Through the design of the bus stop based on the architectural lean startup concept, it is confirmed that the designer repeats the 'Generate-Test-Analysis' to develop the design and generate the final result.
