This study concerns the present possession of CT and MRI machines in Daegu and the technologists' awareness of Quality Control. the study was conducted by visiting forty medical institutions as well as a survey. The survey was carried out by technologists responsible for CT and MRI. CT and MRI machines have only been used in medical institutions in Daegu for a short period. The study revealed that most of them have been acquired by those institutions recently. Most of the technologists who participated in the study are aware of the (prescribed) Quality Control measures and conduct regular inspections in accordance with the quality control chart, however some of them do not.

The purpose of this study is to remind the necessity of reengineering establishment of future-oriented fashion industry and to research the sevices for the system establishment at this present time when the consumer's demands level is extremely high. This research has been done by the literature review of the relative articles, books and the case study. First, through the analysis of the important changes and movements of fashion industry environment by the environmental interpretation model of Draft and Weick, the strategic development, corresponding the environment change of fashion indudtry, has been attempted. Second, this study examined QR integration management method according to the Kunz's behavior theory of the apparel firms. Third, as the prior occupation strategy regarding the things can be done very well from now on the things are needed, the necessity and establisnment of SCM, based on companionship and beyond the boundary between the companies has been studied through the exchange of the data of manufacture and sales which has been regarded as the secret of the companies. Finally, to become a company to lead the market, in addition to the re-organization of the internal process of a company with the leadership which has the clear vision for the consumer's satisfaction, the process have to be integrated under the cooperation with its business partners and the cost have to be reduces, and the time which takes to correspond to the consumer's requirements have to be reduced.

A high proportion of hazardous (PVC, asbestos, chlorinated solvents) and infection wastes are treated in incinerators, the high temperature and high energy characteristics of plasma may be employed to convert waste materials into inert small volume products and combustible gases, plasma torch melting(PTM) is one of the most widely used tool for the vitrification of wastes. The ash product generated is of low bulk density and may also contain leachable quantities of toxic heavy metal and organic species. Plasma processing is able to treat these ashes, destroying any contained polyaromatic hydrocarbons components. Also we presented a steady three-dimensional model for a plasma melting furnace optimum designed in this study with RNG k-ε model, and its use in characterizing the structure of the flow field, temperature field and reaction field. Among various types of plasma torches, non-transferred hollow cathode type torch is best suited due to its long lifetime, easy power controllability and steady power output. Development of a plasma torch showed the lifetime longer than 300 hours and efficiency better than 65% And the various factors(electrode diameter, cooling flow rate and temperature and gas flow rate affecting the thermal efficiency of the torch) were experimentally evaluated.
