Creativity is an ever-increasing research area related to fashion design, namely the documentation and dissemination of creative scholarship. The purpose of this project is to apply creative bridge or creative leap theory to the development of an existing designer's garment collection using the creative design process of an architect. A single case study design was used to investigate the phenomenon of design process creative leap using a direct observation. Results indicate the difficult challenge of producing new and individualized silhouettes for the marketability of clothing, it is apparent that new methods of fostering creativity in designers through non-traditional approaches would benefit the education of apparel designers. Through targeted design practice, educators and practitioners can apply the principles of scientific inquiry into design processes to solve a problem, address a challenge, or create based on personal inspirations.

A worm screw is widely used in a geared motor unit for motion conversion from rotation to linear motion. For mass production of a high quality worm, the current roll forming process is substituted with the milling cutter process. Since the milling cutter process enables the integration of all machining operations of worm manufacturing on a CNC(Computer Numerical Control) lathe, productivity can be remarkably improved. The tooling system for side milling cutter on the CNC lathe to improve machinability is developed. However, the runout of spindle and cutting tips are important factors to be considered for producing high quality worms because the tooling system has multiple tips. In this study, surface roughness variations accuracy according to runout was investigated in side milling cutter for worm screw. The result shows by simulation and experiment.

The process of producing software differs in many aspects from that of traditional manufacturing. Software is not manufactured in the classical sense. Development of software more closely resembles the development effort that goes into design new product [1-3]. In this article, we first describe the foundations of process improvement, which all processes can share. The process improvement differences between software and manufacturing process are then discussed, and a defect driven process inspection and improvement is introduced. Based on the discussion, two experiments were designed and the results of the results were collected. Through the comparison, we found that some efficient quality improvement approaches can be easily adapted in the software improvement and that the inspection efficiency is also significant.

This study examines the performance of pretreatment process system as the initial construction stage of the pretreatment process system to use CGS, a by-product generated in IGCC, as a concrete fine aggregate of construction materials. The process undergoes a grinding process capable of grinding to a predetermined particle size during primary grinding and a sorting plant through sieve grading of 2.5 mm or less for particle size correction. Afterwards, it is hoped that the use of coal gasification slag of Korean IGCC as a fine aggregate for concrete will be distributed and expanded by producing quality-improved CGS fine aggregate using water as a medium for removing impurities and particulates.

1996년도의 유통시장개방을 계기로 소매유통 환경이 급변하기 시작하였으며, 이러한 소매유통 환경변화에 대한 대응력을 강화하기 위해 조직화를 통한 규모화가 산지의 중요한 과제로 대두되고 있다. 이에 산지에서는 여건변화에 대응하기 위하여 소규모 개별농가가 조직화를 통해 전문화·대규모화 되어 가고 있고, 품목별·지역별로 특화되어 가는 양상을 보이고 있다. 하지만 소비지 시장에 대한 경쟁력 강화라는 관점에서는 여전히 문제점을 보이고 있는 것이 사실이다. 이러한 문제점의 가장 대표적인 경우가 시장대응상의 산지유통조직의 조직화·규모화 문제이다. 본 연구에서는 선행연구들을 통한 농산물 유통환경 변화에 따른 산지 조직화 배경 및 필요성, 국내 산지유통조직의 현황 및 문제점, 국내·외 산지유통조직 우수사례를 살펴보고, 조직화·규모화를 중심으로 향후 산지유통조직 경쟁력 제고방안을 위한 개선방안에 대해 제시하였다. 연구 결과, 농산물 소매유통환경 변화에 따라 산지유통조직의 경쟁력을 제고하기 위한 개선방안으로 1) 원물수집 체계 다양화를 통한 가동률 향상 및 조직화 강화, 2) 전문화된 품목의 광역연합마케팅 추구를 통한 규모화 실현, 3) 국외 산지유통조직 우수사례인 프랑스 "브레따뉴 청과물 경제위원회"와 같은 관리 운영조직 설치 및 운영, 4) 국내에 적합한 산지유통조직모델 개발을 위한 지원체계 확립 등의 4가지를 제시하였다. 특히 국내 산지의 경우 산지조직화·규모화에 성공한 각종 사례분석을 통해, 조직적 규모화의 과정 속에서 생겨나는 각종 어려움과 그에 대한 극복방식 등을 일반화 시켜가는 노력이 요구된다.

Spinning is a chipless forming method for producing axially symmetric parts by using axial-radial motions of a spinning roller. This process has still some advantages in such a view point that a variety of complex shapes which can not be formed in a press can be easily spun at a low cost although it is one of the oldest forming methods for spinning mainly cookware parts for a long time. This study is to investigate the optimum roller path in order to obtain the maximum spinnability in producing cylindrical cups of Aluminum(A1050-H16) sheet metal. Working conditions applicable to any size of blank were predetermined through preliminary spinning tests. 9 types of roller path were proposed and experiments were carried out. The modified involute curve was shown to give the maximum drawing ration and more uniform quality of spun cups as compared with other results of this study. in addition thickness distribution and dimensional accuracy of spun cups were examined and discussed.

An extractive fermentation process using pervaporation was studied in a 7 liter fermentor. Pervaporation was performed using a silicone membrane module and a low-acid-producing strain Clostridium acetobutylicu, B18 was used to produce butanol. In batch culture without pervaporation pH 5.5 and initial glucose concentration of 60 g/L resulted in the highest butanol productivity (0.216 g/L$.$h) with butanol yield of 0.261 Butanol flux through the membrane was best at 2.0 L/min-tubing of air flow rate In batch and fed-batch fermentation glucose consumption rate increased by 1.3 times with pervaporation.

The spent fuel slitting device is an equipment developed in order to feed UO$_2$pellet to the dry pulverizing/mixing device. In this study, we have compared and analyzed the handling method of the slitting and that of the pellet and hull, processing time, separating time for 20kgHM, the number of blades, on the existing slitting device using in DUPIC, and spent fuel management technology research and test facility. Also, we have compared and analyzed about an advantage and weak point, designing and producing, processing, establishment, operation, maintenance about the vertical and horizontal slitting device. Based on these results, we have developed the vertical slitting device. By using the results, we have enhanced the slitting processing time(over 40%)in comparison with DUPIC device, and it will is effectively applied to available data for designing and producing of the hot test facility.

Twenty microbial strains producing the acylase were isolated from soil by using Micrococcus luteus ATCC 9341 as an indicator strain, using either D-($\alpha $)-phenylglycine methylester and 7-aminocephalosporanic acid (7-ACA) or glutaric acid dimethylester and 7-ACA as substrates. Among the isolates, only one strain was turned out to be the 7-ACA producer from either cephalosporin C or glutaryl 7-ACA as the substrates by using the overlay of 7-ACA sensitive strain (SS5). 7-ACA produced from cephalosporin C by an isolate (APS20) was detected by high performance liquid chromatography. The isolated strain (APS20) was identified to Bacillus macerans on the basis of cellular fatty acid profile by gas chromatography. Bacillus macerans APS20 had no $\beta $-lacta-mase activity on cephalosporin C, and that is very important for the enzymatic production process of 7-ACA. However, this strain was resistant up to 100 $\mu $g/ml of cephalosporin C.

The application of solar energy, in the field of alternative energy, was on the increase tendency. In the case of advanced nations, through continuous R&D, solar-heat hot-water-boiler with high efficiency has been used for the house and the industrial process on business, advanced nations on reached up the experimental stage of solar generation system. But the actual circumstance of the domestic has been not accomplished the popularization of solar-heat hot-water-boiler and the settlement of it which is the fundamental stage of the solar energy usage. This trouble, the domestic was flooded with small enterprise for producing solar-heat hot-water-boiler, was caused by the popularization and the production without verification of performance. To supply the monitoring program for evaluating solar-heat hot-water-boiler, this research was purpose to improve the technical development of the enterprise for producing solar-heat hot-water-boiler and served as an aid f3r the enlargement and the popularization on solar energy.
