This study is an primary analysis on convergence of porcelain lacquer painting art which is composed of porcelain art and raw lacquer technic. As a part of ceramic art, this study suggest 3 ways of porcelain lacquer decoration with understanding of its history and contemporary status. Lacquer technic gives stability for surface paintings and it also has various media to express its beauty. Porcelain lacquer decoration art contains artistic value and pragmatic purpose for daily life usage. These days, due to unavailability for mass production, it tends to be tried for art work purposes. However this artistic technic and value can be applied to porcelain goods, so that it will raise aesthetic pleasure and cultural diversity.

가상현실 기술이 발달함에 따라 사용자들은 더 현실적이고 사실적인 느낌을 요구한다. 이런 요구를 충족시키고자 여러 기술이 발전해왔는데, 햅틱 기술도 그 중 하나이며, 조각, 디자인, 오락, 의료 등 다양한 분야에서 햅틱 기술을 채택하고 적용하는 추세이다. 이렇게 다양한 분야에서 햅틱 렌더링을 위해 사용하는 모델로는 표면모델이 가장 널리 사용된다. 본 논문에서는 햅틱 장비를 사용하여 다양한 분야에서 가장 많이 사용되는 삼각형 메쉬들로 구성된 표면 모델을 조작하는 실험 및 연구를 진행하였다. 햅틱 렌더링을 위해 필요한 방법들과 시스템의 속도향상을 위한 방법들도 제시한다.

Product designers sketch various ideas of foreground figures(detail design) onto background figures(basic form) and evaluate numerous combinations of them in the late stages of design process. Designers have to test their ideas elaborately with a high-fidelity physical model that looks like a real product. However, due to the requirements of time and expense in making high-fidelity design models, it is impossible to evaluate such a number of combinatorial solutions of background and foreground figures. Contrary to digital models, physical design models are not easily modifiable and so designers cannot easily develope ideas through iterative design-evaluation process. To address these problems, we proposed a new concept 'Augmented Plasticity' that gives morphological editability to a rigid physical object using Augmented Reality technology and implemented the idea as Digital Skin system. Digital Skin system figures out the position and orientation of object surface with ARToolKit visual marker and superimposes a deformed surface image seamlessly using differential rendering method. We tried to apply Digital Skin system to detail design, redesign of product, and material exploration task. In consequence, it was found that Digital Skin system has potential to allow designers to implement and test their ideas very efficiently in the late stages of design process.

The vehicle exterior design is the main parameter of aerodynamic wind noise, but the modification of it is nearly impossible at a proto-type stage. Therefore, it is very important to verify exterior design and estimate the correct wind noise level at the early vehicle design stages. The numerical simulations of aerodynamic wind noises around A-pillar and wiper were developed for specific vehicle exterior designs, but could not be directly used for the discussions with designers because these need complex modeling and simulation process. This study proposes new approach to A-pillar and wiper wind noise estimation at design stage using response surface methodology of modeFRONTIER, of which database is composed of PowerFLOW simulation, PowerCLAY modeling, SEA-Baced (Statistical Energy Analysis-Based) interior noise simulation, and turbulent acoustic power simulation. New design parameters are defined and their contributions are analyzed. A state-of-the-art, easy and reliable CAT (Computer Aided Test) tool for A-pillar and wiper wind noise are acquired from this study, which shows high usefulness in car development.

모든 예술적 표현 활동은 서로 깊은 연관을 지니고 있으며, 복식 디자인 역시 예술적 표현 활동의 한 분야로서, 현대에 이르러 복식은 단순히 입는다는 개념을 탈피한 하나의 조형 예술로 인식되어지고 있다. 예술적 표현 활동은 조형 제작 활동의 주체인 인간이 예술적 표현의 의지를 사물로 객체화하는 과정에 있어서, 그 재료와 재료의 가공 기법을 통해 표현되는 활동이라고 말할 수 있다. 근자에 이르러 종이는 예술표현 활동에 있어서 진정한 표현 매재로 간주되고 있으며, 특히 종이를 예술적 표현을 위한 피동적 표면이라는 재료로서의 고정된 관념에서 탈피하여 입체적 조형이 시도되고, 이러한 종이의 입체로의 성형 가능성에 대한 발견은 조형 매체로서의 종이에 대한 새로운 시각을 제시하고 있다. 이에 본 연구는 종이 조형에 의해 표현되는 조형성을 복식에 적용시키기 위한 것으로서, 종이를 통한 조형성 표현의 여러 방법 중 특히 접기의 방법을 응용하여, 접기 기법의 조형요소로서의 특성과 인체와 결합하여 복식으로 이루어졌을 때 새로운 조형물로 인식되어질 수 있는 복식의 형태를 시도하였다. 작품은 접기 기법에 의해 형성되는 조형성을 복식을 응용하여, 복식에 대한 기하학적 조형성과 함께 새로운 실루엣과 이미지를 창출하며, 복식의 새로운 표현 영역의 확대를 위한 실물 작품으로 제작하였다.

This study is what tried to examine the importance of material in industrial design. Then, if planning is to start of product design, the use of material is the last step to complete design. Design material has existed from the time before mankind were born, and the new material which is useful for human beings is developing rapidly. It is no exaggeration to say that our environment is the aggregation of material which was surrounded with us. Then, material has the timely, spatial and cultural feature as well as physical feature. Besides, all sorts of functions of communicating information are being contained in accordance with the character of material. The outside surface of material has the function to develop the sense organ of human beings. This study examines 4 kinds of cultural features in design materials and shown by findings is as follows : Rrst is the technical progressivity to lead new Design form. Second is the symbolic nature to perform the communication function. Third is the sensible attribute to develop surface effect of Design material. Fourth is the future-oriented nature to convince the future such as new material and technology etc. Thus, so as to perform the competitive product design, it is important to grasp the harmony between material and design, structure and processing, and the substantial meaning that the material has and apply them properly, above all. Because the discovery of material will be the measure to forecast future design.

In generative design computer automatically and quickly generates many alternative design solutions, and the computer algorithms which perform the design tasks are important. The main purpose of this study is to propose a computer algorithm which generates three-dimensional shapes from a two-dimensional digital image such as a photograph or a painting. The base geometry of the final shape is a cylinder or sphere. A surface of the cylinder or sphere is deformed depending on the used image. The proposed algorithm was implemented as a computer program, and the program tested with several famous paintings. The algorithm and results presented in this study implicate the possibilities of the generative design which generates three-dimensional shapes from two-dimensional images. It is necessary to find and measure the values of the generated shape, and it will be a future research to find the relations of emotional and cognitive aspects between the input images and the generated shapes. Those studies are expected to expand the possibilities of generative design.

제품 표면에 코팅을 하는 것은 원자재나 디자인을 개선하는 것보다 훨씬 효과적인 결과를 가져온다. 제품에 코팅을 적용하면 성능과 신뢰성이 향상되어 수명이 증가되고, 소형 경량화가 가능해진다. 자동차 엔진과 그 외의 부품에 적용할 경우 에너지 절감 효과가 있고 친환경 요구에 부응할 수 있어 그 효과가 크다. 시스템의 잠재된 성능은 특정 목적에 따라 맞춤된 PVD/PACVD 코팅에 의해서 향상 될 수 있고, 실제로도 많은 경우 PVD/PACVD 코팅만이 새로운 설계 솔루션을 실현 가능하게 해준다.

A designed object reveals its meaning and image through form, color and material. Among these three elements, material has more powerful influence with its tactile and visual characteristics. In Korea, traditionally materials itself were mainly used to design artifacts rather than various color or formal decoration. The purpose of this study is to investigate the Korean traditional materials, and to classify them by the characteristics of their texture. For this study, the pictures of Korean traditional artifacts were collected from the national museums and literature. Those are architectural and interior elements, furniture, cloths and textiles, arts and crafts. Total of 533 collected artifacts were classified into seven categories, metal, day, stone, paper, wood, straw, fabric things. : 59 metal things, 115 clay things, 62 stone things, 73 paper things, 80 wood things, 47 straw things, 97 fabric things. Each materials were classified into its forming methods and surface treatment focused on the he characteristics of their surface texture. Throughout this study, the uniqueness of forming method and surface treatment of each materials in Korea has been clarified. And furthermore the classification by this various traditional methods of materials will provide plentiful information and ideas to today's designers of the world.
