강원도 태백시 황지의 폐탄광과 폐광석 더미에서 유출되는 산성 광산배수의 유입으로 인한 주변 하천의 오염 실태에 대하여 조사하였다. 하천의 오염도를 알기 위해 하천수와 하상퇴적물의 pH, 황산염이온 농도 및 무기원소 농도를 측정하였으며 하상퇴적물에 서식하는 미생물의 활성을 탈수소효소활성(DHA)으로 측정하였다. 폐탄광과 폐광석 더미의 배수가 직접 유입되는 지천에서는 산성 배수의 유입으로 인해 하천수와 하상퇴적물의 pH 가 중성에서 산성으로 감소하였다. 또한 산성 광산배수가 유입되지 않은 청정지역에서 하상퇴적물의 DHA는 1,176∼4,259g-TPF·g-dry soil()·24h()이었으나 유입되는 지천은 12∼170g-TPF·g-dry soil()·24h()로 매우 낮았다. 청정지역과 비교하여 오염된 지역의 하상퇴적물 중에서 Pb와 Fe의 농도는 각각 37∼46ppm과 40.600∼464,000ppm으로 매우 높았다. 폐탄광 배수의 유입으로 산성화된 하천수에서는 11∼42ppm의 높은 농도의 Al이 검출되었다. 또한 오염된 지역에서 하상퇴적물중의 Mn, Mg 및 Ca의 농도가 청정지역과 비교해서 현저하게 낮았고, 반면에 하천수 중의 농도는 높았다. A survey was carried out to investigate the contamination of streams by the acid mine drainage originated from the abandoned coal mines and coal refuse piles. The physico-chemical characteristics such as pH, sulfate and elements concentrations in the water and sediment in streams were analyzed. Microbial activity in the sediment was evaluated by measuring dehydrogenase activities. At sites contaminated by acid mine drainage, the pH of the water and sediment declined to acidic range from neutral due to the accumulation of sulfate. the dehydrogenase activity ranged from 12 to 170㎍-TPF·g-dry soil()·24h() at the contaminated sites, whereas uncontaminated sites had activities of 1.176∼4.259㎍-TPF·g-dry soil()·24h(). The dehydrogenase activity was significantly affected by low pH of the sediment, indicating that high concentration of sulfate inhibited microbial activity. The concentrations of heavy metals such as Pb and Fe in contaminated sediment (37∼46ppm Pb: 46,000∼464,000 ppm Fe) were much higher than those in the uncontaminated sediment. The concentration of Al in the contaminated water acidfied by coal mine drainage was in the range of 11 to 42 ppm. Compared with those in the uncontaminated sediment, the concentrations of Mn, Mg, and Ca in contaminated sediment were low because of the leaching from soil to water by the acidfied stream water.

Increased Non-permeable areas which have resulted from civilization reduce the volume of groundwater infiltration that is one of the important factors causing water shortage during a dry season. Thus, seeking the efficient method to analyze the volume of groundwater in accurate should be needed to solve water shortage problems. In this study, two different watersheds were selected and precipitation, soil group, and land use were surveyed in a particular year in order to figure out the accuracy of estimated infiltration recharge ratio compared to Web-based Hydrograph Analysis Tool (WHAT), The volume of groundwater was estimated considering Antecedent soil Moisture Condition (AMC) and Curve Number (CN) using Long Term Hydrologic Impact Assessment (L-TH1A) model. The results of this study showed that in the case of Kyoung-an watershed, the volume of both infiltration and baseflow seperated from WHAT was 46.99% in 2006 and 33.68% in 2007 each and in Do-am watershed the volume of both infiltration and baseflow was 33.48% in 2004 and 23.65% in 2005 respectively. L-TFIIA requires only simple data (i.e., land uses, soils, and precipitation) to simulate the accurate volume of groundwater. Therefore, with convenient way of L-TKIA, researchers can manage watershed more effectively than doing it with other models. L-THIA has limitations that it neglects the contributions of snowfall to precipitation. So, to estimate more accurate assessment of the long term hydrological impacts including groundwater with L-THIA, further researches about snowfall data in winter should be considered.

The survey was carried out to investigated the contamination of streams by the acid mine drainage originates from abandoned coal mines and coal refuse piles. The physico-chemical characteristics such as pH, sulfate and elements concentrations of waters and sediments in streams were analyzed, and the microbial activities in the sediments were evaluated by measuring dehydrogenase activities. In sites contaminated by the acid mine dranage, the pH of waters adn sediments declined to acid from neutral due to the accumulation of sulfate. Dehyfrogenase activities ranged from 12 to 170 ㎍-TPF·g-dry soil-¹·24h-¹in the contaminated sites, whereas teh uncontaminated sites had activities of 1,176-4,259 ㎍-TPF·g-dry soil-¹·24h-¹. Dehydrogenase activities were significantly affected by low pH of sediments, indicating that high strength of sulfate inhibited microbial activities. The concentrations of heavy matals such as Pb and Fe in contaminated sediment (37-46 ppm Pb; 46,000 ppm Fe) were much higher than those in the uncontamnated sediments. concentration of Al in the contaminated water acidfied by the abandoned coal drainage was in range of 11 to 42 ppm. compared with those in the uncontaminated sediments, the concentrations of Mn, Mg and Ca in contaminated sediments were low because of the leaching of them from soil to water by acidfied stream water.

장혜진,유희석,임윤경,문세희,장기홍,이정필 대한부인종양 콜포스코피학회 2003 Journal of Gynecologic Oncology Vol.14 No.4

목적 : 재발성 난소암에서 platinum 감수성을 기준으로 2차 항암요법으로 사용한 Carboplatin과 Paclitaxel의 효과를 알아보기 위하여 본 연구를 진행하였다. 연구방법 : 1998년 1월 1일부터 2003년 8월 31일까지 만 5년 8개월 간 아주대학교병원 산부인과에 재발성 난소암으로 입원한 환자 중에서 최초 수술로 난소암을 확진한 후 Cisplatin 또는 Carboplatin 등 platinum 제재가 포함된 항암치료를 받은 후 6개월 이후에 재발한 환자 29명을 대상으로 Carboplatin은 5 AUC를 그리고 Paclitaxel은 175 mg/m^(2)를 투여하였으며, 최소 3회에서 최고 16회까지 투여하였다. 치료효과의 판정은 CT, MRI, Ultrasonography등 영상진단상 암종괴의 크기가 완전히 소실되었을 경우를 완전반응(complete response)으로, 50%이상 감소되었을 경우를 부분반응(partial response)으로, 50% 미만으로 감소되었거나 20% 미만 증가하였을 경우를 불변(stable disease)으로, 그리고 20% 이상 증가되었을 경우를 진행(progressive disease)로 정의하였다. 결과 : 대상 환자에서 완전반응은 6명(21%), 부분반응은 11명(38%), 그리고 불변은 5명(17%)로 전체 반응율 (overall response rate)은 59% 그리고 임상적 유용성(clinical benefit=CR+PR+SD)은 76%이었다. 결론 : 재발성 난소암환자에서 기왕에 사용한 Platinum 제재에 민감한 환자에서는 Carboplatin과 Paclitaxel의 병행 투여가 효과적이었다. Objective : To ascertain the effect of Carboplatin and Paclitaxel combination as a second line regimen for recurrent ovarian carcinoma based on platinum sensitivity. Methods : From January 1st, 1998 through to August 31st, 2003, 29 patients were retrospectively reviewed who had previously underwent primary cytoreductive surgery and adjuvant chemotherapy with Cisplatin or Carboplatin for ovarian carcinoma, and who had later recurred during follow up. All 29 patients had recurred at least 6 months after therapy, and thereafter received second line chemotherapy consisting of Carboplatin (5 AUC) and Paclitaxel (175 mg/㎡) for a minimum of least 3 cycles and a maximum of 16 cycles. Treatment efficacy was assessed by imaging studies including Computerized tomography, Magnetic Resonance Imaging, or Ultrasonography. Complete response was determined as complete disappearance of tumor, partial response at least than 50% reduction in tumor volume, stable disease as less than 50% reduction or less than 20% increase in tumor volume, and progressive disease as more than 20% increase. Results : There was complete response in 6 (21%) patients, partial response in 11 (38%), stable disease in 5 (17%), showing an overall response rate of 59%. The clinical benefit (CR+PR+SD) was 76%. Conclusion : The combination of Carboplatin and Paclitaxel administration seems to be an effective mode of second line therapy in patients with recurrent ovarian carcinoma who had been sensitive to prior platinum based chemotherapy.

관로, 전력구 등 지하매설물의 불투명한 존재여부 및 부정확한 정보로 인해 신규 지하매설물의 계획 노선, 설계, 시공에 많은 문제를 야기시키고 있다. 이에 Ryu(2015) 등은 전기장 해석을 통해 지하매설물의 크기, 위치, 방향 등을 예측할 수 있는 식을 제안하였다. 3개의 현장에 적용하여 싱크홀 존재 여부 및 크기와 지하매설물의 위치, 크기, 방향을 예측하였으며, 예측된 결과를 토대로 설계에 반영되고 후속 조치가 수행되었다. The uncertain existence and insufficient information of underground structures, such as pipe lines and cable tunnels, is causing many problems related to route plan, design, construction of new underground structures. The theoretical equations that is able to predict the location, size, and direction of underground structures through electric field analysis are suggested at the previous study (Ryu., 2015). Three field tests were performed for predicting the location, size, and direction of underground structures and the existence and size of sink-hole. Prediction results were reflected at the design and follow-up measures were performed.
