In this study, the effects of changed environment on spatial extension of flood discharge data which is generating discharge data at ungauged watersheds. Especially, effects of dams on spatial extensions of flood discharge data and on natural flow generation were studied. This is somehow an intial trial of flood discharge data generation for heterogeneous watersheds because of dam installation. Data extensions have been performed based on the flood discharge data from YeoJoo water gauge station located on the Nam-Han River. For the evaluation of flood discharge data spatial extension under dam effects and producing natural flow, 41 flood events associated with YeoJoo water gauge station were selected from 1986 to 2010. When flood discharge data were extended based on YeoJoo water gauge station, 77% of selected flood events were over the satisfaction ranges (NSE>0.5) of Nash-Sutcliffe Efficiency for model validation. Extended flood discharge data at Yangpyung has 0.84 NSE obtained from spatial data extension based on YeoJoo water gauge station. Generated natural flow at YeoJoo was influenced strongly by Chungju Dam which has larger effects on streamflow at YeoJoo than Hoangsung Dam. Observed peak discharges after the 1986 of Chungju Dam installation were smaller than those of the obtained natural flow. Through these results, spatial extension of flood discharge data with installed dams works efficiently for ungauged watersheds and natural flow can be generated using extended flood discharge data.

Crohn ' s disease (CD)와 ulcerative colitis (UC)의 원인은 아직 확실하지 않다. 확립된 연구보고는 없으나 여러 가지 세균이나 바이러스가 원인일수도 있고, 장내세균이 증강인자일수도 있다. 또한, 서양식 식사도 장 점막의 상태와 점막투과성에 영향을 미치기 때문에 역시 증강인자라고 할 수 있다. 각가지의 생활습관도 inflammatory bowel disease (IBD) 발병에 영향을 미치는 요인으로 알려져 있지만, 이들에 대한 다 기능성인자를 규명하는 것은 아직 많은 기초적 연구가 필요하다.

최근 공간정보에 대한 수요가 급증하고, 짧은 갱신주기를 요구하는 경우가 증가함에 따라 상업적인 목적으로 모바일매핑시스템이 자체개발 과정을 거쳐 실용화 서비스를 적용하고 있는 추세이다. 해외에서는 공공 및 민간부문으로 나뉘어 활발히 개발 및 운용되고 있는 실정이다. 본 연구는 모바일매핑시스템의 국내 외 동향 분석과 도로 및 주변 시설물의 파손과 변화에 따른 도로시설물모니터링에 모바일매핑시스템의 활용성을 분석하였다.

K-Means modelling has been tried for finding major DNA marker of ILST035 microsatellite loci in Hanwoo Chromosome 6 linkage map. Major DNA markers are obtained from the ILST035 microsatellite through quantitative trait loci(QTL) and data mining modelling.
