We have investigated a performance of bio-electrode reactor for removal of nutrient like a nitrogen, phosphorus and organic substrate. Lab scale of bio-electrode reactor was operated with synthetic and tannery wastewater. Iron bar and stainless steel used for anode and cathode respectively. In experiment with synthetic wastewater, we were able to obtain the optimal current density range of 2.4-40 mA/dm² after 48 hrs operating time. And in that experiment, about 70~73% of ammonia nitrogen and 54~64% of phosphorus were removed. In experiment with tannery wastewater at 2.4-4.0 mA/dm², the removal rate of ammonia nitrogen, phosphorus and organic substract were about 62-69%, 45~59% and beyond 79% respectively.

목적 : 제일제당에서는 녹농균의 세포외막 단밸질을 유효성분으로 하는 백신인 CFC-101을 개발하였으며, 동물시험에서 이 백신의 안전성과 유효성을 입증하였다. 본 연구에서는 이 녹농균 백신의 인체에 대한 안전성과 면역원성을 평가하는 동시에 인체 접종시의 최적 투여 용량을 결정하기 위하여 제 I/Ⅱa상 임상시험을 수행하였다. 방법 : 건강한 성인 남자를 피험자로 선별하여 각 용량군에 백신투여자 6명, 위약투여자 2명을 배정하였다. 백신 투여군은 0.25mg, 0.5mg 또는 1.0mg 용량의 녹농균 백신을 7일 간격으로 3회에 걸쳐 근육주사 하였으며, 위약 투여군에게는 세포외막 단백질을 제외한 동일한 성분을 투여하였다. 백신접종 후 국소적 또는 전신적인 반응의 발생여부를 관찰하고, 혈액시료를 체취하여 백신의 역가와 유효성을 검정하였다. 결과 : 녹농균 백신 CFC-101은 모든 접종자에서 양호한 내약성을 보였다. 또한 0.5mg 과 1.0mg 백신 투여군에서는 100%의 항체양전율을 나타내었다. 생성된 항체는 녹농균 세포외막단백질에 특이성을 보였고, 녹농균 감염에 대해 방어효능이 있었다. 결론 : 이와같은 결과로부터 이 녹농균 백신은 인체에 안전하게 투여할 수 있으며, 높은 항체 생성능으로 감염방어 효능을 보이고 0.5mg과 1.0mg이 최적용량인 것으로 판단되었다. Background : We developed a Pseudomonas aeruginosa outer membrane protein(OMP) vaccine CFC-101, and the prophylactic efficacy of which has been demonstrated in animal models. In order to evaluate the safety and immunogenicity of the P. aeruginosa vaccine, we carried out a phase I/Ⅱa clinical trial in healthy male volunteers. Methods : Groups of eight volunteers, including two placebo subjects, were vaccinated intramuscularly with three doses of 0.25, 0.5 or 1.0 mg of the vaccine at one week intervals. Sings of systemic and local reactions observed after vaccination were recorded for each vaccinee for 5 days. Physical examinations were performed on days 0, 1, 7, 8, 14, 15, 21, and 42, and clinical laboratory tests were done on days 0, 3, and 21. Blood samples for assay of serum antibody levels were obtained up to 42 days after the first vaccination. Results : The vaccine was generally well tolerated by all vaccinees, showing no significant side effects. In the three dosage groups, all vaccinees, except one receiving the 0.25 mg dose, showed significant elevation in serum IgG antibody titers against the vaccine proteins, indicating 100% seroconversion in 0.5 and 1.0 mg groups. The human antibodies induced by the vaccine were specific for P. aeruginosa OMPs, as confirmed by western blot analysis and immunoprecipitation assays. The capacity of the human antisera to enhance opsonophagocytic killing activity by polymorphonuclear leukocytes and to confer protection against P. aeruginosa infections indicates that the antibodies elicited by the vaccine have protective efficacy. Conclusion : We conclude that the P. aeruginosa OMP vaccine is safe and effective for human use and its optimal dose to be 0.5 or 1.0 mg.

Background: We have doubt about the truth that Type 2 DM is associated with chronic hepatitis C infection. The aim of our study was to prove a close relationship between chronic HCV infection and type 2 DM in korean patients. Methods: We reviewed the out-patient's medical records of 466 patients with type 2 DM who visit the Sung-ae hospital from March 2000 to August 2001. Diabetic patients were analyzed for the following variables: age, sex, waist circumference, weight, waist/hip ratio, using of self monitoring of blood glucose, method of therapy, duration of disease, experience of previous transfusion, major surgical procedure, accompanied disease, liver function tests (LFT), HbA1 c. We ruled out patients with liver cirrhosis. Results: Hepatitis C virus infection was observed more frequently in patient with Type 2 DM. Of 466 Type 2 DM patients, 13 patients were infected with Hepatitis C virus (2.79%). Compared with mean prevalence of Korean population (1.3~1.6%), it's value is very high. the other hand, 21 patients were infected with Hepatitis B virus (4.5%). Such results are similar to mean prevalence of the general public (4~5%). Conclusions: Prevalence of hepatitis C was closely associated in korean patients with type 2 DM. And an increased prevalence is independent of cirrhosis.

하수슬러지 중에 존재하는 HEM에 대해 분석하고, 이를 토양에 사용할 때 발생하는 연간 오염부하량에 대해 추정하였다. 전국의 하수처리장에서부터 수집된 하수슬러지 시료 84점에 대해 분석한 HEM의 평균함량은 27.7±26.5 g/㎏이었고, 최소 1.05에서 최대 194 g/㎏을 나타내어 분석시료간에 큰 편차를 보였다. 하수 처리장이 위치한 도시의 규모에 따라 5단계로 나누었을 매 HEM의 함량은 광역시, 대도시, 중도시, 소도시, 농촌지역에 각각 22.7±16.7, 33.3±25.8, 22.0±8.7, 31.0±30.8, 27.7±25.1 g/㎏을 나타내었다. 미국 EPA의 하수슬러지 토양시용량 기준을 적용하여 농경지, 산림, 공공용지, 개량용지로 분류하고 각각 7,000, 26,000, 18,000, 74,000 ㎏/㏊ (건물량 기준)를 하수슬러지 최대 사용량으로 가정하여 HIM의 연간 오염부하량울 계산하였다. 건물량 기준으로 시용량이 7,000 ㎏/㏊인 농경지의 경우 최대 1,032 ㎏/㏊의 HEM 부하량을 나타내었고, 개량용지 시용기준인 74,000 ㎏/㏊를 적용한 경우 HEM의 연간 오염부하량은 10,908 ㎏/㏊으로 추정되었다. 그 외 산림기준을 적용할 때는 최대 3,832㎏/㏊, 공공 용지 기준을 적용할 때는 최대 2,653 ㎏/㏊의 연간 오염부하량이 추정되었다. To estimate annual pollutant loading rate of n-hexane extractable material (HEM) to soil 84 sewage sludge samples were analyzed. The average content of HEM was 27.7±26.5 g/kg, and ranged from 1.05 to maximum 194 g/kg. According to the number of population of the city the areas were classified as five regions, i.e. big, large, middle, small, and rural area in which the waste water treated plants were grown. The contents of HEM were 22.7±16.7, 33.3±25.8, 22.0±8.7, 31.0±38.8, 27.7±25.1 g/kg, in big, large, middle, small, and rural area, respectively. The applicated areas with sewage sludge to land also were divided as 4 sites by US EPA criteria such as agricultural, forest, public contact sites, and reclamation site. The quantitation of annual pollutant loading rate was estimated using a function (99 percentile concentration = X￣+ 30) when the application amounts were in dosages of 7,000, 26,000, 18,000, 74,000 kg/ha in 5 regions, respectively. The annual pollutant loading rate of HEM to soil by sewage sludge application was maximum 1,032, 3,832, 2,653, and 10,908 kg/ha in agricultural, forest, public contact sites, and reclamation site, respectively.
