Nitric oxide (NO) plays a key role in the processes of inflammation and carcinogenesis. Three isoforms of NO 야mthase have been identified: endothelial 띠띠c oxide 와nth앓e (NOS), neuronal NOS, and inducible NOS (이OS). The purpose of this study was to investigate the characteristics of iNOS expression in 7, 12-dimethylbenz[alanthracene (DMBA)-induced hamster buccal pouch carcinogenesis. Sixty three outbred young (6-week-old) male Syrian golden hamsters were randomly divided into three groups: DMBA treated group (n=57) and non-treated (n=3), and mineral-oil treated group (n=3). No iNOS activity could be detected in the untreated or mineral oil-treated pouches. 80th cytoplasmic and nuclear stainings were observed in the DMBA-treated pouch kera띠lCX까es. There were iNOS expression 외so in the strorna1 cells. The mean values of iNOS expression in the epithelium increased gradually from control to dysplastic lesions and more to invasive squ따nous cell carcinoma. πle clifference between iNOS expr'않sion in the normal and that the dysplastic and carcinomatous lesions is statistically significant. The mean values of iNOS expression in the stroma increased gradually from control to dysplastic lesions and more to invasive squamous cell carcinoma. The difference between iNOS expression in the normal and that the carcinomatous lesions is statistica11y si맑, ificant. In conclusion, this study has demonstrated that iNOS is expressed in DMBA-induced hamster pouch carcinomas. πlis finding suggests that iNOS expression may be associated with the development of chemically induced oral carcmomas.

Since the shoes sewing has been labor-intensive and produces on a large scale, the variation of items sustains much loss and restrict the improvement of labor productivity. The design of the multi-item and small-quantity system requires a survey and investigation for the production system. In this paper, through the questionaires, we analyze and evaluate the line layout, productivity, organization, administration, subsidiary facilities, and work environment. The results of this study may contribute, as a fundamental data, to the plant rationalization, a variety of activities for cost curtailment, and a design of line layout.

The design of experiments says that it's statistical method planning to get the best information of quality characteristics with the least number of times of experiments. This paper aims at analyzing the process capability and at determining an optical condition by experimental designs using the 2-way classification with repitition in order to maintain lower Nacl content and to refine both or a very small quantity of fatty acid and various magnetic jons in the glycerin to use ion exchange resin treatment process. An optimal condition of each level combination in both of passing temperature of cation exchange resin(A₁, A₂, A₃) and of anion exchange resin (B₁, B₂, B₃) is A₃B₃The process capability index is improved form 0.63 to 1.40 and is interpreted as a desirable state. This analysis of process capability by experimental designs will contribute to improving productivity and quality of products.

Nitric oxide (NO) plays a key role in the processes of inflammation and carcinogenesis. Three isoforms of NO synthase have been identified: endothelial nitric oxide synthase (NOS), neuronal NOS, and inducible NOS (iNOS). The purpose of this study was to investigate the characteristics of iNOS expression in 7, 12-dimethylbenz[a]anthracene (DMBA)-induced hamster buccal pouch carcinogenesis. Sixty three outbred young (6-week-old) male Syrian golden hamsters were randomly divided into three groups: DMBA treated group (n=57) and non-treated (n=3), and mineral-oil treated group (n=3). No iNOS activity could be detected in the untreated or mineral oil-treated pouches. Both cytoplasmic and nuclear stainings were observed in the DMBA-treated pouch keratinocytes. There were iNOS expression also in the stromal cells. The mean values of iNOS expression in the epithelium increased gradually from control to dysplastic lesions and more to invasive squamous cell carcinoma. The difference between iNOS expression in the normal and that the dysplastic and carcinomatous lesions is statistically significant.

In these days enterprise's production management have appeared important management department of enterprise management. It is to survive in the market competition and to bring up international competitionality. Among other things. It is required effective and reasonable production management for 'The Productivity Progress and Reduction of Cost'. Factory's production is very which individual enterprise's content and personality as well as become complicated constitution. For the reason, Factory's production has difficulty in that, has build up management system effective organization and rules that has contain individual enterprise situation. M.R.P(Material Requirements Planning) is management technique adapt oneself to this requirement. Computer requisition cost and M package requisition cost were compared. in a M package. As regard it's easily handwork part. Cost for handwork and M package cost were compared. As the result of comparison. M package cost proved inefficient than efficient M.R.P design

열 필라멘트 CVD법에 의한 다이아몬드 박막합성과 기판 사전처리의 영향

다이아몬드 증착시 기판의 표면처리를 변화시켰을 때 다이아몬드의 핵생성 밀도에 미치는 영향에 대하여 연구하였다. 실험장치는 열 필라멘트 CVD 장치를 사용하였고, 반응가스로 메탄과 수소가스를 사용하였다. 기판의 표면 처리는 탄소 상을 기판에 증착시키는 방법, Soot에 의한 기판 표면처리, 혹연에 의한 기판 표면처리로 크게 3가지로 행하였다. 모든 경우에 핵생성 밀도가 증가하였으나 탄소 상을 증착시킨 경우와 soot에 의한 사전처리의 경우의 핵생성 밀도의 증가가 혹연에 의한 처리보다 더 현저하였다. 또한 탄소강의 증착의 경우 표면에 굴곡이 없는 매우 평탄하고 균일한 다이아몬드 막을 얻을 수 있었다. 사전증착처리 한 기판에 탄소 층을 형성시켰을 때 탄소 층과 기판과의 접착력이 약한 것을 이용하여 다이아몬드 막을 쉽게 분리시켜 free standing 다이아몬드 박막을 얻을 수 있음을 알았다. Effects of the substrate pretreatment on uncleation density of the diamond thin films have been investigated. The film was prepared using the hot-filament CVD reactor with the mixture of methane and hydrogen. The substrate pretreatment was done in three different ways: predeposition of carbon on the substrate, soot on the substrate, and graphite on the substrate. All three cases enhanced the nucleation density of diamond. And the effect was more marked in the first and the second cases than in the third one. In the first case where the substrate was predeposited by the carbon phase, a very smooth and uniform film of diamond could be obtained. Since the bound strength between the substrate and the predeposited carbon phase is relatively weak, separation of the diamond film layer from the substrate was found to be easy.
