  • The distribution pattern of water quality parameters and phytoplankton biomass in upper inflow rivers of lake Paldang had surveyed. In North-Han river system, nutrient concentrations and algal biomass was below the standard of mesoand oligotrophy from lake Soyang to lake Paldang, maintaining good water quality, except the N5 site located near the Chuncheon-Si, showing high nutrients concentrations and algal biomass. The algal biomass of the South-Han river system showed oligotrophic level in the upstream near the lake Chungju, and increased along the flow direction showing eutrophic level in the downstream within the lake Paldang area. On the other hand, the highest concentrations of nutrients were detected in the middle stream near the Yeoju-Si and Yangpyung-Gun rather than in the downstream suggesting algal biomass in lake Paldang would not come from the upper river area but come from the growth within the lake area using nutrients from the upper inflow river.

  • In hydrology analysis, the result of a slope analysis for terrain have an very important effect on water quality and water quantity Recently, a slope analysis tend to use the digital elevation model rater than the traditional map sheet. But a terrain slope analysis by the digital elevation model depends on grid size of the digital elevation model. Hence the effect of a slope analysis by the digital elevation model is a important factor. In this study, therefor, in order to determine a hydrological parameter and a terrain parameter for simulation of the water quality and the hydrological property, we adapted two sample area that are the Nerin stream of the basin of the Soyang lake and a Osip stream of Samchuk, and its individual coverages are $640\;km^2$ and $33\;km^2$. Also to analyze the effect of grid size in the slope of a basin, we apply DEM changing a grid size respectively at intervals of 100 m from 100 m to 1.000m for the Nerin stream basin and at intervals of 10 m from 20 m to 300 m for the Osip stream basin.

  • Occurrence frequency of flood and drought tends to increase in last a few decades, leading to social and economic damage since the abnormality of climate changes is one of the causes for hydrologic facilities by exceedance its designed tolerance. Soil and Water Assessment Tool (SWAT) model was used in the study to estimate temporal variance of groundwater recharge and baseflow. It was limited to consider recession curve coefficients in SWAT model calibration process, thus the recession curve coefficient was estimated by the Baseflow Filter Program (BFLOW) before SWAT model calibration. Precipitation data were estimated for 2014 to 2100 using three models which are GFDL-ESM2G, IPSL-CM5A-LR, and MIROC-ESM with Representative Concentration Pathways (RCP) scenario. SWAT model was calibrated for the Soyang watershed with NSE of 0.83, and $R^2$ of 0.89. The percentage to precipitation of groundwater recharge and baseflow were 27.6% and 17.1% respectively in 2009. Streamflow, groundwater recharge, and baseflow were estimated to be increased with the estimated precipitation data. GFDL-ESM2g model provided the most large precipitation data in the 2025s, and IPSL-CM5A-LR provided the most large precipitation data in the 2055s and 2085s. Overall, groundwater recharge and baseflow displayed similar trend to the estimated precipitation data.

  • Objectives : To find appropriate constitutional therapy by understanding Hyeong and Gi from the perspective that "Gi is inner position, and Hyeong is outer position, and Yang converts to Gi, Eum makes Hyeong(氣裏形表, 陽化氣 陰成形)". Methods : 1. Defined Hyeong(形)and Gi(氣)and studied Wonhyeong(圓形) and Banghyeong(方形), the shapes that are formed as a result of Gi-movement. 2. Used 'Hyeong-Gi' concept to analyze physiological and pathological phenomena; classifies parts of the body into Sasang by extrapolating from WonBang concept; and studied Sasangchejil. 3. Based on the above 1 and 2, studied medical direction of Sasangchejil written in Hwangjenaegyeongsomun Tongcheon Results : 1. Wonhyeong is the result of Yang(陽) movement, whereas Banghyeong is the result of Eum (陰) movement. 2. Hyeong(body) can be classified into Won(圓, circle) and Bang(方, square) or more specifically into Won of Won, Bang of Won, Won of Bang, Bang of Bang. Each corresponds to Taeyang(太陽), Soyang(少陽), Taeeum(太陰), and Soeum(少陰). 3. The constitutional therapy can be formulated by refering to "Tongcheon(通天)" and by taking into consideration that each Sasang constitution has a bias toward Mok(木), Hwa(火,) Gum(金), Su(水). Conclusions : Basic treatment for round shaped people needs to be focused on a cure of Boeum(補陰) and Bojeong(補精), whereas for angular shaped people, treatment should be about Bogi(補氣) and Boyang(補陽). Treatment for Taeyangin(太陽人) should be about strengthening Ganeum(肝陰) and reducing Paeyang(肺陽) and for Soyangin(少陽人), the treatment needs to be strengthening Sineum(腎陰) and diminish Biyang(脾陽). Taeeumin(太陰人) should receive a cure that reinforces Pyeyang(肺陽) and brings Ganeum(肝陰) down, whereas Soeumin(少陰人) should have a cure that strengthens Gi and increases Yang.
