The three main processes involved in the design of stressed membrane surface are surface form-finding, stress analysis and cutting pattern generation. The last process, cutting pattern generation, is considered as a very important procedure in the aspect of the practical design for the fabric membrane surface. In this paper, The cutting pattern generation technique using the geodesic line algorithms is first introduced. And the numerical examples resulting from this technique are presented. Cable elements are used for the approximating membrane surface and two kinds of model, square line and central line model, are used in pattern generation. Finally, a number of different cutting pattern generation for the same membrane surface is carried out and the numerical results are compared each

본 논문에서는 다단 논리회로의 고장을 완벽하게 검출할 수 있는 테스트 패턴 생성기를 설계하였다. 이 테스트 기법은 테스트 패턴 생성 논리회로를 사용하여 생성하였다. 생성된 테스트 패턴은 기존의 전체 테스트 방법에 비해 패턴을 크게 감소시켰다. 이 테스트패턴 생성기는 다단 논리회로에서의 모든 고장을 검출할 것으로 본다. 여러 가지 I.C 테스트 방법 중에서 어떤 방법을 선택할 것인지는 고장검출 속도에 영향을 준다. 가장 중요한 것은생산단가이며 설계된 테스트 패턴 생성기는 저가형이다.

Recently, a hyaluronic acid micro needle patch for therapeutic and cosmetic purposes has been used by attaching directly to the skin with a pattern having a micro needle shape of 1/3 thickness of hair. These products are attracting attention as an innovative product that maximizes the effect by activating the active ingredient in the skin in the deep skin without blocking the horny layer because the micro needle shape exists on the patch surface so that it can penetrate effectively to the skin. Currently, DAB (droplet air blowing) or MEMS technology is used to make pattern shapes for patches. Because of this technology, manufacturing time is long and manufacturing cost is high, so we tried to develop the mold technology to machine the microneedle shape directly to the metal. In this study, we first fabricated a needle pattern with a quadrangular pyramid shape and finally produced a conical needle pattern.

The aim of the research is to develop a PC based courseware which is programed to drafts clothing patterns. The pattern making are numerically formulized. The of the program were as follows；1. Menu and instructions are displayed in Korean Language. 2. Easy step-by-step instructions explaining how to draw basic pattern and design pattern. 3. Low cost personal computer and general purpose printer are used. The source program was written in C-language and compiled using Turbop C. The Bezier spline is used to draw curves of pattern and to display Korean characters and pattern on same screen simultaneoulsy, Korean characters are drawn graphically. The low cost IBM Personal Computer or compatibles with Hercules Graphic Card is required to run this grogram.

The purpose of the study is to identify the designers' and the patterner's pattern making, draping and the use of dress form in domestic companies of designer's brand to present basic information for effective pattern works. It turned out that the designer brand companies at home use flat pattern and draping at the same time rather than draping only The effects of the use of draping lies in unique designs and elastic materials, which seems proper phenomena for the current design trend such as high duality and diversification. But, draping has such problems that the pattern takes long time to be finished and that the staffs don't acquire well the needed skills due to the lack of draping education. To secure the high added value of fashion, it is required to develop education programs for new skills and to apply draping actively. Also, it requires an educational system in which practice oriented skills are cultivated, and efficient investment into apparel business.

Marbling dyeing technique shows beautiful flowing pattern because the pattern is transferred to the medium by the pigments floating onto the viscous solution base. However, this marbling pattern does not have any reproducibility and the result of accidental pattern formation. Marbling process contains many complicated procedures such as making marbling base, mordanting the medium, and bubble removal with size limitation. Computer changed the many aspects in textile design and digital technique is used in many design production. However, it is impossible to produce marbling pattern with digital drawing. In this research, the digital textile design starting from marbling pattern was developed for digital textile printing. Marbling was done to produce the initial motifs and scanned. Several marbling media such as silk, polyester, and paper were used. Photoshop was used to process and develop textile design based on these marbling motifs. One repeat was developed and various colorways were tried. The developed textile design were printed using DTP.

As the IT industry rapidly progresses, the functions of electronic devices and display devices are integrated with high density, and the model is changed in a short period of time. To implement the integration technology, a uniform micro-pattern implementation technique to drive and control the product is required. The most important technology for the micro pattern generation is the exposure processing technology. Failure to implement the basic pattern in this process cannot satisfy the demands in the manufacturing field. In addition, the conventional exposure method of the mask method cannot cope with the small-scale production of various types of products, and it is not possible to implement a micro-pattern, so an alternative technology must be secured. In this study, the technology to implement the required micro-pattern in semiconductor processing is presented through the photolithography process and plasma etching.

The purpose of this study is to investigate the fitness according to drafting method of the block patterns for women in Korea. The major findings of this study are as follows: 1. According to each sensory test of the frontal view, back view, side view and silhouette Block Pattern I is the best of them in summation of the sensory tests score. Block, Pattern D and I have good shape too. However the best block Pattern D shows good score in evaluation of overall fitness and silhouette. 2. Most of block patterns, which show high scores in sensory tests, are the Compromise Method taking merits of the Proportional Method and Short Measure Method among the Pattern Drafting Methods. Box-shape patterns show low score in the sensory tests. 3. Regarding to the number of measurement, the patterns of the Compromise Method using 6-8 measurements seem to be optimal. In degree of fitness, loose fit type basic patterns are better than other patterns from a viewpoint of the total satisfaction.

최근 개인정보 유출 사건으로 이를 이용한 2차적 피해에 대한 우려가 높아지고 있다. 아이디와 패스워드 같은 정보가 유출되더라도 추가적인 피해를 막기 위한 대책이 필요하다. 본 논문은 똑같은 단어를 타이핑 하더라도 사용자 마다 다른 패턴을 분석, 추출하여 로그인 시스템에 적용하는 기법을 제시한다. 즉 타인이 본인의 패스워드를 알아내 입력하더라도 다른 타이핑 패턴으로 인해 접근을 막는 시스템이다. 이를 위해 개인의 타이핑 패턴을 추출하는 알고리즘을 개발하고 이것을 바탕으로 적정 수준의 일치성을 가지는 패턴을 찾아내는데 이용할 수 있다.
