In order to development of culture goods I made works with various color's silk fabrics dyed with water extract or methanol extract of plants. The Plants used for dyeing as dyeing material were indigo, safflower, amur cock tree, onion's Peel, citrus peel, mugwort, gromwell, sappan wood. Each of Plants were extracted by each of temperature and time. The mordants used for various color chanties are aluminium sulfate, cupric acetate mono hydrate, ferrous chloride. With fabrics of various color dyed like this I made works which give expression to an easy and natural image of the Korean nation of fabrics.

제품 생산 공정에서 주로 사용하는 담체에 인디케이터나 제품 용액 등을 코팅할 경우 온도 습도 조도 등 외무 요인에 의해 제조조건이 상이해지고 공정 시간 및 품질에 영항을 준다. 본 논문에서는 RGB 값을 통하여 백색도를 측정하여 담체에의 코팅 균일도를 측정할 수 있는 센서 시스템을 구현한다. 구현 시스템은 대량으로 발생되는 센서 데이터 정보를 저장 분석 및 기술적 해석을 통한 다양한 파라미터들을 조정함으로서 공정 진행과 코팅 결과의 최적합성을 유도하고, 다양한 유사제품들의 생산 공정의 모니터링 및 자동화 시스템 개발에 적용이 가능하다.

This paper presetns modifications of a hydraulic shovel to robotize, and we derive a dynamic model of the hydraulic shovel arms,and hydraulic analysis are discussed . Then , our purpose is making to imitate a target railroad line of the grinder position by the PID control. Moreover, to determine the gains of the PId controller, we referenced the Ziegler and Nichols' method. In this paper, we demonstrated that the PID control is available for system. These results indicated the possibility of practical use fo the deburring robot with the hydraulic shovel.

It is well blown that the product development time in manufacturing industry is critical. A new methodology for a product design knowledge management is required to reduce design errors and to optimize a design process. In this paper, Process-Related design knowledge management and Document Template are introduced to provide a design process to prevent previous design errors and a solution for the desist errors. Also the Document Template is more convenient interface in integrating the design knowledge into a system.

The purpose of this study is to investigate the backstaining generated during cellulase treatment for indigo-dyed denim. The results were as follows. 1. High generating conditions of the backstaining were as same as best conditions for cellulose activity (temperature at 6$0^{\circ}C$, pH at about 4.5~5.5, treatment time at 40 min. and enzyme concentration at 2g/l). And also, liquor ratio, sample weight and repeated-use cycle of liquor had influenced on the backstaining. 2. The backstaining was decreased about 30~40% when various additives, that is, surfactant, anti-backstaining agent (C.M.C) and softners were added. 3. A application of image processing on the backstaining evaluation was more effective than method by reflectance, particullarly in out of level fabrics. In image analysis, the backstainings were measured by histogram between 256 gray levels.

We prepared natural indigo/calcium hydroxide complex powder from tinctoria's leaf, according to the demand of developing new dyeing technique of natural fibre with natural indigo. FT- IR and UV/Visible spectra were operated to find the dyeing properties of synthetic indigo and natural indigo powder. Cotton, flax and silk fabrics were dyed with different pH, dye concentration and dyeing time. The colour yield of indigo dye was quite sensitive to dye bath pH and fabric. In synthetic indigo, the highest K/S value of dyed silk fabric was shown at near pH 9.0, and which of flax and cotton fabric were shown at pH 11.0. In other hand, in the case of natural indigo complex powder, the highest K/S value of dyed silk fabric was shown at near pH 8.0, and which of flax and cotton fabric were shown at pH 9.5∼pH 10. Mercerized cotton fabric dyed with natural indigo powder has a little antimicrobial activity.

Cotton fabric was dyed with indigo at different pHs, dye concentrations, and repeated dyeings. And the K/S value and dye uptake of the dyed materials at those conditions were determined. The decrease of pH during the reduction process of indigo stock solution was observed. As a result the decrease of pH of the dye stock solution depended on the dye concentration and initial pH. The highest K/S value was shown at fabric dyed at pH 11 and the relationship between K/S value and dye uptake depended on initial pH of reduction bath and the slope was lower as the pH increased to 13.

This paper implemented the tools to measure the risk of the modules for the web application project written in ASP, using the Indicator of the Module Risk Levels. The Indicator of that is developed by GSFC group in NASA based on structural programming language and gives us software product quality metrics. The implemented tools examined with the ASP projects of the practical business. As the results the data shows the module risk levels easily, and then the data affects the maintenance to improve the application quality.
