The purpose of the present study is to examine the flow characteristics of ER fluids between 2 port and 3 port rectangular tube brass electrodes. ER fluid is made silicon oil mixed with 2-3wt% starch having hydrous particles. Flow visualization of the ER fluids were obtained by CCD camera measuring those of the clusters using an image processing technique. This research found the flow rate(Q_(L)) with 0 kV/mm, 0.5kV/mm and 1.0kV/mm for Q_(L) = 0, 0 and 5.73cm³/s. When the strength of the electric field increased, the cluster of ER fluids are clearly strong along the rectangular tube and the flow rate(Q) decreased.

Background : The reported incidence of early gastric cancer located in the upper portion of the stomach has been increasing with the recent advances in its diagnosis and screening. Recently, we have successfully performed laparoscopic assisted proximal gastrectomy and gastric tube reconstruction without pyloroplasty on three patients with early gastric carcinoma localized to the upper third of the stomach. We describe our modification of this procedure in this report. Method : After creating an surgical pneumoperitoneum, the stomach was mobilized using laparoscopic coagulating shears. Upper half of the greater curvature and three-quarters of the lesser curvature were then dissected along with regoinal D2 lymphadenectomy. This was followed by a 5 cm, longitudinal mini-laparotomy in the upper abdomen, and the construction of the exteriorized stomach with a gastric tube measuring 20 cm long and 4 cm wide. Reconstruction with an esophagogastrostomy was performed using a circular stapler. Result : No post-operative morbidity or mortality was observed in this small series of patients. The average operative time was 250 minutes (range 220-300 minutes), and the average blood loss was 150 ml (range 90-180 ml). The mean number of lymph nodes harvested during these laparoscopic proximal gastrectomies was 24 nodes (range 22-25 lymph nodes). The average postoperative hospital stays was 7.5 days (range 7-8 days). Conclusion : Our technique of laparoscopic assisted proximal gastrectomy and gastric tube reconstruction without phloroplasty offers a minimally invasive technique with the potential of impoving the post-operative quality of life patients with an early-stage proximal gastric cancer.

Effect of Acute Ethanol Intoxication on Hepatic Rhodanese Activity in Rats with Extrahepatic Cholestasis

곽춘식,--,--,-- THE KOREAN SOCIETY FOR BIOMEDICAL LABORATORY SCIEN 2004 Journal of biomedical laboratory sciences Vol.10 No.2

Liver and serum rhodanese activities were determined in acute ethanol intoxicated rats with extrahepatic cholestasis induced by common bile duct ligation (CBD) to manifest the biochemical background of alcohol drinking hazard under the hepatobiliary disease. Liver cytosolic and microsomal rhodanese activities and these Vmax values in CBD ligated rats with acute ethanol intoxication were found to be decreased much more than that in CBD ligation alone. However, the difference of Km value on above hepatic enzyme was not found between the experimental groups. On the other hand, serum rhodanese activity in CBD ligated rats with acute ethanol intoxication was greater increased more than that in CBD ligation alone. These results indicate that the biosynthesis of the hepatic rhodanese decreases and the serum rhodanese activity increases in cholestasis combined with acute ethanol intoxication. reflecting damage of aggravated hapatocytic membrane. Accordingly, the resulting data supported the fact that alcoholic drinks were enzymologically harmful to the hepatobiliary disease.

신중두,임동규,김건엽,박문희,고문환,엄기철 한국환경농학회 2003 한국환경농학회지 Vol.22 No.1

Consoli가 설명한 것처럼 전과정평가의 개념 및 일반적인 정의에 따르면, 전과정평가는농업생산에 관련된 환경영향을 평가하는데 부합하는 방법이라고 생각되며, 특별히 전과정 평가방법인 Eco-indicator 95는 농업 체재에 대한 환경영향을 분석하는데 적절한 기법인 것으로 입정되었다. Eco-indicator 95 method를 이용하여 지구온난화 및 수계 부영양화와 관련된 시비체계에 따른 벼 재배에 대해 비교할만한 분석체계를 이루었다. 그렇지만 본 연구에서 전화정평가 항목에 기록된 모든 관련 정보가 환경 영향에 고려되지 않았기 때문에 Eco-indicator 95 method를 농업생산 체계에 적용할 때 몇 가지 난제에 부닥친다. Eco-indicator 95 method에 토양 및 자원의 이용과 같은 몇 몇 중요한 환경적인 문제가 포함되지 않았으며, 이 방법의 다른 문제는 환경 평가를 위하여 현장 정밀연구가 수행되지 않았다는 것이다. 그렇지만 본 연구에서 얻어진 생태지표 지수를 이용하여 벼 재배에 따른 시비방법 간의 차이점을 나타내기에 충분하다고 여겨지며, 가장 높은 생태지표 지수를 나타낸 화학비료를 시용한 구에서 가장 큰 환경영향이 관측되었고, 이러한 차이점은 주로 화학비료 투입에 의한 토양중의 높은 인산 함량의 축적 때문인 것으로 여겨진다. 분석한 시비체재는 특별히 지구온난화 보다는 수계의 부영양화의 환경적인 문제에 기여되는 것으로 나타났으므로 질소 시용비율 및 시용기술 이외에 액비 시용에 따른 양분 용탈이 수계 환경에 명확히 영향을 미치는 것으로 나타났다. The suitability of the Life Cycle Assessment (LCA) methodology to analyze'the environmental impact of rice cultivation with different fertilizing systems is investigated. The first part of an LCA is an inventory of parameters used and emissions released due to the system under investigation. In the following step, the Life Cycle Impact Assessment, the inventory data were analyzed and aggregated in order to finally get one index representing the total environmental burden. For the Life Cycle Impact Assessment (LCIA) the Eco-indicator 95 method has been chosen because this is well documented and regularly applied impact assessment method. The resulting index is called Ec -Indicator value. The higher the Eco-indicator value the stronger is the total environmental impact of an analyzed few system. The rice field experiment conducted in middle parts of korea was chosen as an example for the life cycle impact analysis. In this experiment the treatments were consisted of none fertilizer plot (NF), standard fertilizer plot (SF) applied chemical fertilizers based on soil chemical analysis before rice transplan ing, and efflux fertilized plot (EF) applied with pig wastes fermented as the same rates of SF plot as basis on total nitrogen content. The obtained Eco-indicator values were clearly different among the treatments in the rice trial. The total Eco-Indicator values for SF and EF have been observed 58 and 38% relative to the NF, respectively. For all the treatments the environmental effects of eutrophication contributed most to the total Eco-indicator value. The results appeared that the LCA methodology is basically suitable to assess the environmental impact associated with different fertilizer applications for rice cultivation. A comparative analysis of the fertilizing system's contribution to global warming and eutrophication is possible.

윤순강,김원일,김진호,김선종,고문환,엄기철 한국환경농학회 2002 한국환경농학회지 Vol.21 No.4

본 연구는 동진강 유역의 수질 보전을 위한 기초자료를 얻기 위하여 동진강 본류와 이에 유입되는 정읍천을 대상으로 2001년 5월부터 11월까지 수질 모니터링을 실시하였다. 동진강 본류의 수질은 BOD기준으로 상수원 Ⅱ~Ⅳ등급(2.84~6.45 ㎎/L)으로 지점별로는 DJ6(정읍천 합류후)이 4.07㎎/L로 높게 나타나 Ⅲ급수의 수질을 유지하였다. COD는 지점별로 11.20~32.96 ㎎/L의 범위로 정읍천 합류후의 농도가 32.96 ㎎/L로 가장 높게 나타나 정읍천을 통한 본류의 오염물질량의 증가를 알 수 있었다. T-N의 경우 4.16~5.84 ㎎/L의 범위로 유역 전반에 걸쳐 오염이 이루어지고 있는 것으로 나타났고, T-P의 경우 BOD, COD와 마찬가지로 정읍천 합류후가 0.19 ㎎/L로 타 지점에 비하여 놀게 조사되었다. 본류의 COD의 경우 장마후 갈수기에 높은 농도를 나타냈고, T-P의 경우는 하천의 유량이 증가하는 홍수기보다 장마전 갈수기의 오염정도가 높고 이후 장마후 갈수기로 갈수록 수질이 악화되는 것으로 조사되었다. 동진강 수질의 오염은 주로 하류로 갈수록 그 정도가 심하게 나타나는데, 이것은 정읍천을 통해 유입되는 도시 생활하수와 인근 공장단지의 산업폐수가 그 주 요인으로 오염물질(BOD, COD T-N 및 T-P)의 농도가 상승하는 주원인이 되고 있다. 따라서, 동진강 수계의 수질관리를 위해 주 오염원이 되고 있는 정읍천의 도시생활하수와 공장단지에서 방류되는 산업폐수의 제어에 대한 대책이 먼저 이루어져야 할 것으로 판단된다. Irrigation water quality along Donjin river watershed was monitored to find a possible pollutants, for maintaining water quality to achieve food safety through water quality preservation of river. As a pollution indicators, such as Biological Oxygen Demand(BOD), Chemical Oxygen Demand(COD), Total Nitrogen(T-N), and Total Phosphate(T-P) in Dongjin river were examined from May to November in 2001. The results were as follows : The BOD level of Dongji n river ranged from 2.84 to 6.45 mg/L, which would be in a Ⅱ~Ⅳ grade of the potable water criteria by Ministry of Environment. Averaged BOD level of downstream DJ6(After Jeongupcheon confluence) was 4.07 mg/L. The average COD level of Dongjin river ranged from 11.20 to 32.96 mg/L. COD level of DJ6 rapidly increased rapidly after the junction of Dongjin river and Jungupcheon because it showed the latter had relatively high pollution level. T-N content were significantly high in all sites of Dongjin river ranged through 4.16 to 5.84 mg/L. T-P examined high concentration than another thing point by 0.19 mg/L after Jeongupcheon confluence as BOD and COD. COD of main stream was expressed high concentration to dry season after rainy season. In case of T-P, pollution degree of dry season before rainy season appeared and examined that quality of water was worsened go by dry season after rainy season. The water quality of Dongjin river was deteriorated with inflow of Jungupcheon polluted by municipal and industrial sites near Jungup city.

윤순강,이종식,정구복,김민경,김선종,고문환,엄기철 한국환경농학회 2002 한국환경농학회지 Vol.21 No.4

본 연구는 만경강 유역의 수질 보전을 위한 기초자료를 얻기 위하여 만경강 본류와 이에 유입되는 지천을 선정하여 2001년 5월부터 11월까지 매월 수질 모니터링을 실시하였다. 만경강 유역내 본류 및 지천의 유기물과 영양염류 함량을 조사한 결과, 본류의 T-N은 3.78~12.68 ㎎/L였으며, 지천중 축산폐수가 유입되는 익산천의 농도가 가장 높았다. 본류의 T-P의 BOD는 각각 0.043~0.864 ㎎/L와 2.59~13.29 ㎎/L였으며, 지천중 익산천이 가장 높았다. 본류의 COD는 12.9~119.5 mg/L였으며, 지천중 도시생활하수가 유입되는 추천이 가장 높았다. 만경강 유역 수질저하의 주 원인은 축산폐수였으며, 도시생활하수가 그 다음으로 중요한 원인으로 평가되었다. 만경강 본류의 T-N과 T-P는 하천의 유량이 증가하는 홍수기인 7~8월보다 장마선 갈수기인 5~6월에 높았고, COD는 장마전 갈수기보다 홍수기에 높았으며 장마가 완전히 끝난 영농후 갈수기인 9~11월에도 수질저하가 지속되었다. 만경강에 유입되는 지천중 전반적으로 수질오염이 심각한 익산천과 추천은 영농후 갈수기에 수질이 가장 저하되었고 상대적으로 홍수기에는 양호하였다. A survey on four tributaries along with Mankyeong River was carried out to get the information for the water quality improvement and control. Typical paddy farming were major agricultural practices in Kosancheon and Soyangcheon. Iksancheon was livestock raising watershed. Chucheon was urban watershed. Water quality in six sites of main stream and four sites of tributaries in Mankyeong River were investigated from May to August in 2001. The concentration of nutrients in main stream of Mankyeong River were in the range of 3.78~12.68 mg/L for total nitrogen, 0.043~0.864 mg/L for total phosphorus, 2.59~13.29 mg/L for BOD and 12.9~119.5 mg/L for COD, respectively. Water quality of Mankyeong River mostly exceeded the standard water quality criteria of Korea. Major causes of water pollution were evaluated as sewage of swine and urban area. Among the four tributaries, water quality in agricultural practices, Kosancheon and Soyangcheon was relatively less polluted. While, the highest level of water pollution measured in Iksancheon was due to livestock The water quality of Iksancheon and Chucheon was generally more polluted in the dry period than in rainy period.

Hyun-Su Park,Ki-Young Kim,Mun-Sik Shin,Tae-Hwan Noh,Jong-Cheol Ko,Young-Jun Mo,Woon-Cheol Shin,Jeong-Kwon Nam,Bo-Kyeong Kim 한국육종학회 2012 한국육종학회 심포지엄 Vol.2012 No.07

Japonica rice cultivars exhibit high susceptibility to bacterial blight(BB) disease due to genetic vulnerability in Korea. Korean japonica resistant rice cultivars mainly possess one of the genes, Xa1 or Xa3 for BB resistance. These resistance genes are becoming susceptible to K3a, resulting in serious rice yield reduction. This study was carried out to confirm the effect of xa13 gene pyramiding for developing of japonica rice cultivars resistant to BB pathogen breaking down Xa1 or Xa3. IRBB4 conferring Xa4 gene was resistant to K1(HB01013), K2(HB01014), K3(HB01015), and moderately resistant to K3a(HB01009). IRBB5 having xa5 gene was resistant to K1, K2, K3, and K3a. The recessive gene xa13 was resistant to K1 race but susceptible to K2, K3, and K3a. But Xa21 gene is susceptible to predominant K1 race but resistant to other races such as K2, K3, and K3a. Two genes Xa3 and xa13 were susceptible and Xa4 gene was moderate resistant to 24 isolates. xa5 and Xa21 genes were resistant to all isolates including K3a. When xa13 gene combined Xa4, xa5 and Xa21 genes, effect of xa13 gene pyramiding showed higher resistant reaction than that having singe gene out of Xa4, xa5, and Xa21. The order of resistance against 24 isolates breaking down Xa3 gene was IRBB55(xa13+Xa21) > IRBB53 (xa5+xa13) > IRBB51 (Xa4+xa13).
