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 characteristics were compared through first-flushing and statistical analyses. The mean of the water quality parameters was the highest in Seolseongcheon during dry days among the three watersheds. EMCs of biochemical oxygen demand (BOD) and total nitrogen (TN) were higher

Melanotic neuroectodermal tumor of infancy (MNTI) is a rare pigmented tumor generally occurring in the head and neck region in children 12 months of age or younger. Approximately 380 instances of this tumor are reported in the medical literature. We presented a case of MNTI that occurred in the left temporal bone of a 2-month old female infant. And, the clinical assessment, histologic diagnosis, and management is reviewed.

본 연구에서는 RHESSys (Regional Hydro-Ecologic Simulation System) 모형과 관측 자료를 이용하여 유출량, 증발산량, 토양수분량, 총일차생산량과 순광합성량을 평가하고자 한다. 수문생태모형인 RHESSys는물, 탄소 및 질소순환과 지형 공간적 변화에 따른 물질이동을 모의할 수 있다. 대상유역은 설마천 유역(8.5 <TEX>$km^2$</TEX>)으로 우리나라 북서쪽에 위치하고 있다. 유역의 90%이상이 산림유역이고, 토양은 대부분 사양토이다. 2007~2009년의 관측 일유출량을 이용하여 유출량을 검 보정하였고, 증발산량은 에디 공분산 방법에 의한 플럭스 타워로부터 관측되었으며 토양수분은 신뢰할 만한 실측자료를 바탕으로 모형의 보정(2007~2008) 및 검증(2009)을 실시하였다. 또한 지구의 탄소순환을 규명할 수 있는 식생의 순광합성량과 총일차생산량에 대한 모형의 검 보정은 Terra 위성의 MODIS (Moderate Resolution I

BACKGROUNDEarly goal-directed therapy (EGDT) has been used for patients with severe sepsis and septic shock in the emergency department (ED). In 2003, international management guidelines for severe sepsis and septic shock were developed under the auspices of the Surviving Sepsis Campaign (SSC); however, EGDT based on the SSC was not fully evaluated in the ED. The purpose of this study was to evaluate the efficacy of EGDT based on the SSC in the ED in Korea.METHODSWe randomly assigned patients wh

Accurate monitoring of snow cover is a key component for studying climate and global as well as for daily weather forecasting and snowmelt runoff modelling. The few observed data related to snowmelt was the major cause of difficulty in extracting snowmelt factors such as snow cover area, snow depth and depletion curve. Remote sensing technology is very effective to observe a wide area. Although many researchers have used remote sensing for snow observation, there were a few discussions on the ch

For most upland crops in Korea, underground water is used to ensure an adequate water supply. Thus, surface water storage tanks are needed to supply surface water from reservoirs or streams. This study discusses the design, manufacture and monitoring of a water storage tank capable of reliably supplying water to crops and preventing the inflow of floating debris. The study was conducted in an apple orchard in Yesan-gun, Chungcheongnam-do in Korea. Based on the water requirements of the crops and
