The purpose of this research is to obtain the characteristics of water-vapor separator for improving the evaporative surface. The experimental system is constituted with water vapor generator, vapor storage tank, laser source for visualization and camera for photography. The efficiency of water-vapor separator can be varied by the kinds of the inside materials. Thus, in this report, we introduced the three kinds of materials with wire scrap, wire brush and sponge. As the experimental results, the wire brush was showed the best efficiency with 185 g/hr.

Developing a new commercial product, it is need to connect the end users demand of quality to the industrial technology of company. for the reason, this study is to build up the users demand for imminent marketing product of a certain company by AHP(Analytic Hierarchy process), analyse quantitatively users subjective thoughts collected by Group Consensus, calculate the added-value of users demands and verify the consistency of users opinions by consistency-exponential-calculation. The added value obtained by this method is substituted into a user-demand item of QFD(Quality Function Development). and, the technical characteristic data transferred from the extracted essential factor for developing and manufacturing a new product is substituted into a technical characteristic item of QFD. The faculty of quality is firstly finished by this procedure. But, because the relation a technical characterization with users demand do not be known in new product, Wassermans method was introduced for correlation users demand with technology and for the processing and marketing of a new product. The all assumption on the thesis was based on the reliable real data of a certain company.

Poly(3-perylenylmethyl methacrylate)의 합성

具廣謨,全一鍊 慶一大學校 1993 論文集 Vol.9 No.1

In order to obtain a high molecular weight polymer containing the pendant perylene chromophore, poly(3-perlenylmethly methacrylate)(PPeMMA) was selected. PPeMMA monomer was prepared by the reaction of 3-hyddroxymethylperylene with methacryloyl chloride in tetrahydrofuran in the presence of triethylamine at room temperature. PPeMMA polymer was prepared by azobisisobutyronitrile-initiated radical polymerization of PeMMA in benzene. The PeMMA and the corresponding polymer were characterized by spectroscopic methods. The polymer was insoluble in ordinary organic solvents.

Abstract - The biggest difficulty the small and small business currently face is not to have the effective operation of management system that is the computerization of management, and the problem is the small and medium-sized company can not afford the expenses caused by maintaining and operating such huge man-powers and facilities. Therefore, in this study, we try to develope the Quality Information System allowing the effective outflow and management of information through the availability lf viewing and managing the information by the level by menas of setting the log-in levels for the operation of information, easy revision or medification in the changed structure and new assignment made and followed by the modularization of program. For the accomplishment of above purpose, the material coding work or process allowing the easy classification of materials by emplyees of the company through the in-house standardization of material classifying standard is the foundation for the fast data processing so, it must be achieved first. And also, the purpose of this study is for inducement of the production management and quality control operated by companies to the computerization and automation, and we try to develop the DB Design allowing the realtime monitoring the ordered quantity to quantity to be delivered and output through a unit of PC and the increased consequence with the other works by monitoring the output at the site through the central PC instead of the system monitoring the output at the site by the manager for accomplishment of this purpose.

본 연구는 거세한우 육성우에 대한 황토 첨가급여가 발육에 미치는 효과를 구명하고자 발육능력, 사료섭취량을 규명한 바 아래와 같은 결과를 얻었다. 전 시험기간 동안의 평균 일당증체량은 대조구와 황토급여구가 각각 0.91㎏과 0.87㎏/day로 대조구가 높은 것으로 나타났지만 유의성은 인정되지 않았다. 사료섭취량은 대조구와 황토급여구 모두 평균 일일 두당 농후사료 섭취량이 2.42㎏이었으나, 건초섭취량에 있어서는 각각 3.02와 3.14㎏으로 황토급여구가 다소 높은 경향으로 나타났다. The study was conducted to investigate the effect of dietary supplements of reddish clay on the growth performance in growing Hanwoo steers. A total of 8 calves was allocated into 2 feeding groups, control(basal diet) and treatment(basal diet plus ad libitim Reddish clay) for Hanwoo steers. This study was carried out for 5 months with a total of 8 calves. The results obtained in the present studies are summarized as follows : Average daily gains throughout the experimental period of 4 months to 9 months of age were 0.91 and 0.87㎏ for control group and reddish clay-supplemented group, respectively, however, no statistical significances were found. Average daily intake of concentrates was 2.42㎏ for each group, while that of hay tended to be higher in reddish clay-supplemented group(3.14㎏) than in control group(3.02㎏).

Salmonella균 증식에 있어서 Ferric Citrate의 영향

유승모,고광균 순천향의학연구소 1995 Journal of Soonchunhyang Medical Science Vol.1 No.2

This study was performed to find a method of more high isolation rate of salmonella infection among the patients suspected of salmonellosis. Especially, there are several inhibitors in most popularly used S-S agar medium for increasing the selectivity of salmonella therefore, the formation of colonies is very low. So, I investigate the effect of the ferric citrate of an ingredient of S-S agar medium on the growth of salmonella. 1. The growth of all Salmonella spp. is inhibited in agar plate medium including low concentration of ferric citrate and as increasing the concentration of ferric citrate of the medium, inhibition of the growth of salmonella is greater. 2. Especially the growth of Salmonella enteritidis is inhibited in a medium including 0.1% ferric citrate. 3. Therefore, in order to increase the rate of isolation, it is proper to use the differential medium than to use selective medium.
