www.eymj.org Kung Sun Oh was born on October 4, 1878 in Gongju, South Chungcheong Province, Korea. His pen name Hae Gwan (海 觀) means “to see the world in humanity” (Fig. 1). Prior to the emergence of Western medicine in Korea, two Koreans had ventured off to learn the practice thereof in the US: Jaipil Soh (Philip Jaisohn in English, 1864–1951) and Jeomdong Kim (Esther Park in English, 1876–191...

Systematic consideration of uncertainty in data, model structure, and other factors is generally unaddressed in most Total Maximum Daily Load (TMDL) calculations. Our previous studies developed the Management Objectives Constrained Analysis of Uncertainty (MOCAU) approach as an uncertainty analysis technique specifically for watershed water quality models, based on a synthetic case. In this stu...

Image segmentation is the process of partitioning a digital image into multiple segments. Segmentation is fundamental step in analyzing and understanding an image. In this paper, different segmentation algorithms are implemented. Watershed transform is region based segmentation technique. It changes your image into another image whose catchment basins are the objects you want to identify. Where...

The Muskingum-Cunge flood routing procedure has been incorporated into the Natural Resources Conservation Service Technical Release 20 (TR-20) hydrologic model. The TR-20 model is an event watershed hydrologic model used to analyze impacts of watershed changes (land use, reservoir construction, channel modification, etc) on volume of runoff and peak discharge. Rainfall runoff modeling is very i...

Recent findings in the Umpqua River Basin in southwestern Oregon illustrate a tension in the rise of both community-based and watershed-based approaches to aquatic resource management. While community-based institutions such as watershed councils offer relief from the government control landowners dislike, community-based approaches impinge on landowners' strong belief in independence and priva...

watershed scale irnpact. Our objective was to estimate the watershed scale impact of grass buEers by comparing sediment and agichemical losses from two adjacent 14 1 165 hectare watersheds, one with conservation buffers and one without. Rainfall derived m o f f events frorn 2002-2003 were monitored for water runoff, TSS, phosphorous and atrazine loss. A conservation-watershed included 0.8 Ism o...

BACKGROUND AND PURPOSE The watershed cortical areas are the first to be deprived of sufficient blood flow in the event of cerebral hypoperfusion and will be the sites of watershed microinfarcts. Cerebral hypoperfusion is associated with Alzheimer disease (AD), but information regarding the occurrence of watershed cortical infarcts in AD is lacking. METHODS Brains of 184 autopsy cases (105 def...
