This study investigated the management environment of medium and small business by examining the role of medium and small business in national economics, the change in management condition, and the problems in Qualify and technique. Also we analyzed problems in the past quality control activity of our medium and small business, and examined the driving direction and introduction method of QM. And to understand the effect of manager's concern in quality management to observe the quality system before and after introduction of QM. A target for this investigation is the medium and small business which has introduced QM through ISO 9000.

Qualify Engineering(QE) is purposed for company profits. It is difficult to understand the literature of QE which is published in Korean. In this paper, we want to make easy understanding of the QE and to apply it to real fields. Though that Taguchi has contributed to QE is absolute, QE and Taguchi methods are not the same methods. In this paper, we are trying to show differences of those. QE methods also are developed from the design of experience, the design of parameter and the on-line control of production process. Nowadays, the main subject of QE are to determine control variables and noise variables.

Using the CNG(compressed natural gas) and LPG(liquified petroleum gas) as the automotive fuel will be expanded because of their clean effect to the environmental air qualify. But these programs of gas using expansion would have a difficulty due to public consideration of gas utilities as a big hazard. The Ministry of Environment has an ambitious plan to substitute more than 25,000 buses with CNG and ensure more than 200 CNG refueling stations as well by the year of 2007. However, it is very difficult to establish new CNG and LPG refueling stations because of expanded safety distance than ever before by several major explosion accidents.

Recently SAMWOO EMC received order and built interior walls which was used the day process in several high-rise compound buildings. On the way to build, this process was brought about several matter according to the progress and qualify control. So, this study is the improving way of the dry process from experiences on those constructions

Taguchi's parameter design seeks proper choice of levels of controllable factors (Parameters in Taguchi's terminology) that makes the qualify characteristic of a product optimal while making its variability small. This aim can be achieved by response surface techniques that allow flexibility in modeling and analysis. In this article, a collection of response surface modeling and analysis techniques is proposed to deal with the multiresponse optimization problem in experimentation with Taguchi's signal and noise factors.

Computer software users develop and utilize their application software by themselves since Processing methods are different by quantity and qualify of the information The developed model needs input data and error numbers generated during the testing phases. However. total error numbers of the existing model and each error time was needed as data for developing the new model. But, maximum likelihood estimation must be used to exponential model of binomial-type and estimating of parameters by using the searched data. Parameter estimation can be done with trial and error or simulation.

Near-infrared(NIR) reflectance spectroscopy was employed to qualify various ploymorphs. We collected 8 potential polymorphs forms of Medicine T for this study. Near-infared spectra of the powder samples contained in glass vials were obtained over the wavelength region of 1100-1750nm. There were the peak around 1560nm in the 6 spectra among 8 spectra. Principal component analysis(PCA) has been performed to examine the qualitative difference of 8 polymorphs PC space. (omitted)

공기 중에 존재하는 미생물(바이오에어로졸, bio-aerosol)은 많은 질병 발생의 원인이다. 의학계에서는 바이오에어로졸과 공기 매개성 질병의 전파와의 연관성이 잘 알려져 있다. 특히 결핵, 수두, 홍역, 천연두의 발병은 공기를 통한 질병 전파의 중요성을 확인시켜 준다. 그러나 IAQ(indoor air qualify)의 영향은 최근에서야 조사되었다. 보건의료기관과 연구실험실에서는 세균과 진균의 감염이 HVAC 시스템을 통해서 종종 일어난다. 유사한 IAQ연구에서는 바이오에어로졸이 빌딩증후군과 같은 빌딩과 관련된 질병(building-related illness, BRI), 감염, 중독성 증상, 민감성 질병과 1차적으로 연결되어 있음을 발견되었다.

Recently, automated construction machines have been developed for technically solving construction industry problems such as labor, productivity, qualify and the profit decrease. In spite of the importance of performance analysis in order to commercialize the automated construction machines, previous studies are mainly forced on developing hardware and software of automated construction machines. The primary objective of this research is to propose the performance analysis model of automated construction machines, which can measure productivity, quality and safety improvement rate based on the research and development phases, and to develop a performance analysis system, which enables performance evaluator to easily analyze the performance of the automated construction machines. Finally, it is anticipated that the effective use of the performance analysis model and computerized system would be able to develop the automated construction machines having high performance, and to establish the marketing strategy effectively in order to increase the possibility of commercialization of the developed construction machines.
