Objective: Occupational medicine specialists in the Busan, Ulsan and Kyung-Nam areas established an area-based occupational disease surveillance system and used this system to collected case information for the purpose of preventing occupational diseases Methods: l l hospital participated in this system. The authors selected five main diseases, which were hand-arm vibration syndrome (HAVS), work-related musculoskeletal disorder (WRMSD), occupational asthma, occupational skin disease and occupational and occupational lung cancer and established their case definitions. All cases were reported on the web, and real time analysis was conducted. Results: Between April 2001 and April 2003, 192 cases of HAVS, 118 cases of WRMSD, 33 cases of occupational asthma, 17 cases of occupational skin disease and 17 cases of occupational lung cancer (for a total of 377 cases of these five main diseases) were reported. most of the HAVS cases came from shipbuilding, and 172 of them (92.7%) were associated with grinding. Of the four main types of WRMSD, carpal tunnel syndrome (CTS) was the most prevalent with 46 cases and shipbuilding was also the main industry involved (83.9%). The ergonomic risk factors involved mainly associated with the hand. In 19 (57.6%) and 4 (12.1%) cases of occupational asthma, the agents involved. The causative agents of occupational lung cancer included Cr, welding fume, PAH, Ni, etc. 10(58.8%) of the cases were diagnosed as squamous cell carcinoma and 5(29.4%) as adenoma. Conclusion: This result showed that an area-based occupational disease surveillance system might provide an effective method of evaluating the prevalence of such diseases, however the Busan, Ulsan and Kyung-Nam provinces are too large to be treated as individual areas. Therefore, the authors suggest that each province should establish its own surveillance system.

몇가지 植物의 棲息地 造成에 關한 硏究

윤종선,김익환,신세균,심우경,이철희,신영철 韓國植物ㆍ人間ㆍ環境學會 1999 인간식물환경학회지 Vol.2 No.2

종의 棲息密度가 낮아지고 있는 하늘나리, 섬초롱, 자란 3종의 식물을 인위적으로 棲息地를 造成하기 위하여 국립공원 속리산 등산로변 標高 200m, 400m, 600m 지점에 150주식 종당 450주를 조직배양 및 분주에 의하여 육묘 된 묘를 이식하여 생존상태 및 棲息地 造成의 가능성을 2년에 걸쳐 검토한 결과는 다음과 같다. 1. 造成 棲息地의 토양의 理化學的 造成은 pH 5.2∼5.6, 유기물 함량 29∼54g/㎏, CEC 9.4∼11.5㎝ mol(+)/㎏으로 산성을 띠고 있었으며, 유기물 함량은 높은 편이었고, 염기치환용량은 낮았으나 비교적 우리나라 典型的 山地土壤의 理化學的 造成과 유사하였다. 2. 棲息地內 생장기간의 投光率은 標高 200m 지역은 10.8∼11.6%, 400m lw역은 10.8∼11.4%, 600m 지역은 11.0∼12.8%로 식재식물의 生長環境에 부족한 상태였다. 3. 식재 식물 수는 식재 후 활착율은 3종 모두 양호하였으나, 점차 감소되었으며, 특히 자란의 감소율이 높았다. 감소의 원인을 분석한 결과 하늘나리, 섬초롱, 자란 모두 굴취나 절취의 피해가 많았으며, 특히 자란은 凍害에 의한 枯死가 1년차 72∼86주, 2년 차에서 19∼35주로 조사도어 자연상태에서의 越冬은 어려운 것으로 나타났으며, 집중호우에 의한 流失도 감소의 한 원인이었다. 4. 식재식물의 생장상태는 불량하였는데 이는 投光量 부족으로 판단되어 棲息地造成時에는 錄陰期 投光量에 대한 사전 검토가 중요한 요인으로 나타났다. 5. 개화율은 섬초롱과 자란에서 높았으며 標高가 높을수록 개화기는 2∼4일 늦어지고 휴면기는 빨라지는 경향이었다. 식물 棲息地 造成時에는 造成 식물의 생장에 적합한 토양, 光環境 등을 고려한 위치 선정이 중요하며, 上層林에 의한 遮光으로 下層 초본식물 遷移速度가 빨라짐으로써 光環境 개선을 위한 上層林의 間伐, 周邊樹種의 更新이 요구된다. In order to make the artificial habitats of Lillium concolor, Campanula takesimana and Bletilla striata that the number of plant became sparse, 150 plants per species were transplanted at the region of 200m, 400m and 600m above sea level. And the growth of plants and the potential as habitats creation were analyzed. In the physical and chemical properties of soils in the there, soil pH was 5.2 to 5.6, organic matter content was 29 to 54g/㎏ and cation exchange capacity(CEC) was 9.4 to 11.5㎝ mol(+)/㎏. The transmittance rates of sunlight of the habitats during the growing periods were 10.8 to 11.6% in the 200m region, 10.8 to 11.4% in the 400m region and 11.0 to 12.8% in the 600m region. These transmittance rates were deficient for normal growth of plants. After the plants were transplanted, the survival rates of three species were high in common but the rates decreased gradually. Especially the decrease rate was high in the Bletilla striata. The causes of decrease were digging and cutting by climbers, sweeping asay by rainfall and freezing damage. Especially, the cold tolerance of Bletilla striata was weak in the natural condition. The growth of planted plants was poor, and it was assumed that the reason was shortage of sunlight transmittance. The flowering rates were high in the Campanula takesimana and Bletilla striata. And as the elevations were high, the flowering was later by 2 to 5 days but the dormancy was earlier. In the artificial making of plant habitats, the growth environment of plants have to be considered to choose the suitable region. And, because the habitats are shaded by the trees and bushes, the thinning of trees and the change of species are needs to improve the light transmission.

But WBC in mouse fed sunflower seed was higher the that ao the other treantment groups r-GTP and total cholesterol level of mouse fed sunflower seed were high, but BUN was low

소재 관련업체 및 기관과 신소재연구소의 상호 정보교환 시스템 구축

박재윤,안영철,전병세 경남대학교 신소재연구소 2002 신소재연구 Vol.14 No.-

현재 국내 부품소재 산업은 제조업 총 생산액의 약 30%를 차지하는 주요산업이며, 향후 그 규모가 확대될 전망이다. 그러나, 산학간의 관계에 있어서는 상대방에 대한 정보가 제한되어 있기 때문에 중소기업의 애로기술을 해결하기 위한 산학협동이 어려운 실정이다. 따라서 경남대학교 신소재연구소에서는 산학간의 정보교환을 원활하게 하고 중소기업의 애로기술을 해결하고자 부품소재관련 전문 홈페이지를 구축하였다. 본 연구에서는 중소기업 및 경남대학교의 구성원이 신소재연구소의 홈페이지를 쉽게 사용할 수 있도록 홈페이지의 내용을 설명하고자 한다. Currently, parts and materials industry is the major part of the domestic manufacturing industry occupying 30% of the market and the share is expected to increasingly grow. However, as far as the relationship between the industry and the university is concerned, it is very difficult to develop an industry-university cooperation to solve a technological difficulties of the medium and small sized enterprises because of the limited amount of informations between them. Therefore, a homepage for parts and materials has been constructed in the Institute for Advanced Materials in Kyungnam University to facilitate free exchange of informations between industry and university and to solve technological difficulties of the industry. In this study, the contents of the homepage are introduced in detail for the users in the medium and small sized enterprises and Kyungnam University.

양윤주,하영철,송정근,홍창희 東亞大學校 附設 情報通信硏究所 1999 情報通信硏究所論文誌 Vol.7 No.1

본 논문에서는 VLSI 전체 전력소비에 있어 비중이 높은 클럭 시스템의 전압 스윙 폭을 줄여 전력소비를 감소시킬 수 있는 저전압 클럭용 플립플롭을 제안한다. 제안된 플립플롭이 저전압 스윙 클럭으로도 동작함을 증명하고 이 플립플롭과 연계하기 위한 실제 전압 폭 감소 클럭 드라이버를 설계하였으며, 이 클럭 드라이버에 의해 기존의 클럭 드라이버에서 발생하는 전력소비를 1/4가량 감소시킬 수 있음을 설명했다. 본 논문에서 제시하는 플립플롭과 클럭 드라이버간의 연계동작과 소비전력 감소 효과는 SPLICE simulation을 통해 검증하였다.

In this paper, we developed a simulation model of a car parts assembly line to improve the system performance such as worker's utilization balancing, productivity. This simulation model has been developed using QUEST, a true 3D discrete event simulation packcage that is designed for modeling and analysis of manufacturing systems. We have suggested the results obtained to improve the system performances of an existing production line.

다범주 순서형 품질특성을 갖는 제품의 최적 공정조건 결정에 관한 연구

김상철,윤원영,전영록 한국품질경영학회 2004 품질경영학회지 Vol.32 No.3

This paper deals with an optimal process control problem in production of hull structural steel plate with high defective rate. The main quality characteristic(dependent variable) is the internal quality(defect) of plates and is dependent on process parameters(independent variables). The dependent variable(quality characteristics) has three categorical ordinal data and there are 35 independent variables(29 continuous variables and 6 categorical variables). In this paper, we determine the main factors and to develop the mathematical model between internal quality predicted probabilities and the main factors. Secondly, we find out the optimal process condition of main factors through analysis of variance(ANOVA) using simulation. We consider three models to obtain the main factors and the optimal process condition: linear, quadratic, error models.
