Faulty field sensors cause unreliability in the observed data that needed to calibrate and assess hydrology models. However, it is illogical ignore abnormal or missing values if there are limited available. This study addressed this problem by applying imputation replace incorrect recover streamflow information dataset of Samho gauging station at Taehwa River (TR), Korea from 2004 2006. Soil Water Assessment Tool (SWAT) two machine learning techniques, Artificial Neural Network (ANN) Self...
The Warburg effect is important for cancer cell proliferation. This phenomenon can be flexible by interaction between glycolysis and mitochondrial oxidation energy production. We aimed to investigate the anticancer effects of pyruvate dehydrogenase kinase inhibitor, dichloroacetate (DCA) respiratory complex I inhibitor metformin in liver cells. DCA and/or on HepG2, PLC/PRF5 human lines, MH-134 murine hepatoma primary normal hepatocytes using MTT assay. Inhibition lactate/ATP production...
Abstract The generation of human oligodendrocyte progenitor cells (OPCs) may be therapeutically valuable for demyelinating diseases such as multiple sclerosis. Here, we report the direct reprogramming somatic into expandable induced OPCs (iOPCs) using a combination OCT4 and small molecule cocktail. This method enables A2B5 + (an early marker OPCs) iOPCs within 2 weeks retaining ability to differentiate MBP-positive mature oligodendrocytes. RNA-seq analysis revealed that transcriptome O4 was...
Three watersheds in Korea (Dochoncheon, Gongjicheon, Seolseongcheon) with different land cover characteristics were selected for non-point source pollution monitoring. Event mean concentration (EMC) was calculated, and runoff compared through first-flushing statistical analyses. The of the water quality parameters highest Seolseongcheon during dry days among three watersheds. EMCs biochemical oxygen demand (BOD) total nitrogen (TN) higher Dochoncheon Gongjicheon rainy days, respectively....
The negative changes in the hydrological cycle are increasing due to climate change and urbanization, resulting deterioration of water quality environmental issues. Although Low-Impact Development (LID) techniques studies have been conducted solve this problem, spatial distribution LID facilities sewer types has received less attention. In study, it is proposed analyze effects type, facilities, type on runoff using Storm Water Management Model identify effective ways improving Non-Point...
본 연구에서는 SWAT(Soil and Water Assessment Tool) 모형을 이용하여 미래 기후변화가 충주댐 유역(6,585.1 km<TEX>$^2$</TEX>)의 하천수질에 미치는 영향을 분석하고자 하였다. 기상자료는 IPCC에서 제공하는 A2, A1B, B1 배출시나리오를 포함하는 ECHAM5-OM 모형의 결과를 과거 30년(1977-2006, baseline period) 기후자료를 바탕으로 편이보정(bias correction)과 Change Factor Method로 Downscaling 6년(1998-2003) 동안의 일별 유출량 및 월별 수질(SS, T-N, T-P) 자료를 보정 검증을 실시한 후, Downscaling된 ECHAM5-OM의 시나리오에 대해 2020s, 2050s, 2080s로 대별되는 미래의 수문학적 거동 변화 하천수질 변화를 전망하였다. This study is to assess the future potential impact of...
본 연구에서는 SLURP 장기 수문모형을 이용하여 미래기후와 예측된 토지이용자료 및 식생의 활력도를 고려한 상태에서 하천유역의 수문요소에 미치는 영향을 분석하였다. 경안천 상류유역(<TEX>$260.4\;km^2$</TEX>)을 대상유역으로 선정하여 4개년(1999-2002) 동안의 일별 유출량 자료를 바탕으로 모형의 보정(1999-2000)과 검증(2001-2002)을 실시하였다. 보정 검정 결과 Nash-Sutcliffe 모형효율은 0.79에서 0.60의 범위로 <TEX>$R^2$</TEX>는 0.77에서 나타났다. 미래 기후자료는 IPCC(Intergovernmental Panel on Climate Change)에서 제공하는 A2, A1B, B1 기후변화시나리오 의 MIROC3.2 hires, ECHAM5-OM 모델의 값을 이용하였다. 먼저 과거 30년 기후자료(1977-2006, baseline)를 각 모델별 20C3M(20th Century Coupled...
The analysis of endocrine disrupting compounds (EDCs) and pharmaceutical personal care products (PPCP), present at trace level in surface waters, is often expensive, time-consuming, complex. Implementing effective monitoring strategies for these essential to determine the types analytes, sampling locations, frequencies. Multivariate analyses were used investigate patterns EDCs PPCPs Lake Mead, Nevada, purposes. results cluster principal component identify among demonstrated that selected...
The impact of the channel geometry on water quantity and quality simulation Soil Water Assessment Tool (SWAT) was evaluated for Andong Dam watershed. new equations to determine bankfull width channels bottom floodplains were developed using aerial photographs, its performance compared with current SWAT. more exact than since tended overestimate widths floodplain. When observed data, streamflow scenario 2 (S2, applying equations) showed lower deviation higher accuracy 1 (S1, because peak flow...
The important role of WT1 in early folliculogenesis was evident from its restricted expression pattern immature follicles and involvement transcriptional control inhibin-α FSH receptor. There is also considerable evidence that a potent inhibitor apoptotic cell death the developing kidney male germ cells, suggesting it could play regulation follicle survival. Therefore, we evaluated if involves survival granulosa cells (GCs) during FSH-independent stage. GCs were obtained small preantral rat...
Contaminants of emerging concern (CECs) are raising public awareness because their potential effect on aquatic ecosystems and health. For this study, the authors applied spatial analyses to four selected US watersheds identify critical areas susceptible CECs used watershed characteristics (i.e., source distribution, land use, climatic hydrologic conditions) prioritize types CECs. The results identified sub‐basins where major wastewater treatment plants located as for CEC point pollution in...
Engraftment of oligodendrocyte progenitor cells (OPCs), which form myelinating oligodendrocytes, has the potential to treat demyelinating diseases such as multiple sclerosis. However, conventional strategies for generating oligodendrocytes have mainly focused on direct differentiation into forebrain- or spinal cord-restricted without establishing amplifying stem/progenitor cells. Taking advantage a recently established culture system, we generated expandable EN1- and GBX2-positive...
The Ministry of Environment in Korea aims to reduce non-point source (NPS) pollution and improve soil water management by expanding NPS priority areas. Six areas suspended solids (SS) according loss were chosen as they either constitute serious hazards the natural ecosystem due pollutants or are with unusual geologic structure strata. Although more comprehensive standards required for effective management, however, no detailed consideration factors available legal provisions. Therefore, this...
Rapid and accurate diagnosis of foot-and-mouth disease viruses (FMDV) is essential for the prompt control FMD outbreaks. Reverse transcription polymerase chain reaction (RT-PCR) real-time quantitative RT-PCR (qRT-PCR) are used routine FMDV as World Organisation Animal Health-recommended diagnostic assays. However, these PCR-based assays require sophisticated equipment, specialized labour, complicated procedures detection amplified products, making them unsuitable under-equipped laboratories...
