For the Hancheon drainage area in Jeju island, a groundwater flow model using Visual MODFLOW was developed to simulate artificial recharge through injection wells installed in the Hancheon reservoir. The model was used to analyze changes of the groundwater level and the water budget due to the artificial recharge. The model assumed that $2{\times}10^6m^3$ of storm water would recharge annually through the injection wells during the rainy season. The transient simulation results showed that the water level rose by 39.6 m at the nearest monitoring well and by 0.26 m at the well located 7 km downstream from the injection wells demonstrating a large extent of the affected area by the artificial recharge. It also shown that, at the time when the recharge ended in the 5th year, the water level increased by 81 m at the artificial reservoir and the radius of influence was about 2.1 km downstream toward the coast. The residence time of recharged groundwater was estimated to be no less than 5 years. The model also illustrated that 15 years of artificial recharge could increase the average linear velocity of groundwater up to 1540 m/yr, which showed 100 m/yr higher than before. Increase of groundwater storage due to artificial recharge was calculated to be $2.4{\times}10^6$ and $4.3{\times}10^6m^3$ at the end of the 5th and 10th years of artificial recharge, respectively. The rate of storage increase was gradually diminished afterwards, and storage increase of $5.0{\times}10^6m^3$ was retained after 15 years of artificial recharge. Conclusively, the artificial recharge system could augment $5.0{\times}10^6m^3$ of additional groundwater resources in the Hancheon area.

The pumping capacity of riverbank filtration using radial collector wells at the Geum, Yeongsan, Seomjin, and Nakdong rivers was evaluated using Milojevic's equation. Assessment of the radial collector wells' pumping capacity in riverbank filtration was carried out using a case study in which one set of collector wells is installed in the watershed of each river. Nakdong River was evaluated to have the highest pumping capacity for riverbank filtration. The areas capable of producing over 10,000 $m^3$ per day were found mostly in the Nakdong River.

Objectives : It is known that the five Su points are very useful clinically. The following study was undertaken in order to find out the general characteristic and the origin of the five Su points. Methods: We investigated the relation of symptoms that are treated by five Su points and Shi-Dong Suo-Sheng-Bing(是動 所生病). The main reference book was Zhen Jiu Jia Yi jing(鍼灸甲乙經) and the author took Liver Meridian of Foot Gworeum(足厥陰肝經) as an example. Results : 1. Five Su point of Liver Meridian of Foot Gworeum(足厥陰肝經) treats Shi-Dong-Bing(是動病) of Liver Meridian of Foot Gworeum. It is peculiarity of Five Su point of Liver Meridian of Foot Gworeum, differed from the others acupoints. Symptoms of Shi-Dang-Bing appears with the abnormal pulsation of Merdian Gi(脈氣), and the special feature of Shi-Dang-Bing is the symptoms are consisted of disorders of whole body, trobles of an internal organ, and psychosomatic disorders. 2. In <Su Wen San Bu Jiu Hou Lun (素問 三部九候論)>, it is described the part of pulse feeling for Shi-Dong-Bing(是動病) of Liver Meridian of Foot Gworeum(足厥陰肝經) as ‘A region that is 2 Chon(寸) from the basic digital joint of the first toe’. This region is agree with the acupoint of Liver Meridian of Foot Gworeum in <Mai-Jing(脈經)>, <Qian-Jin-Yao-Fang(千金要方)>. And Haeng-gan(行間) Tae-chung(太衝), members of five Su-points of Liver Meridian of Foot Gworeum is situated the same region. So we suppose that the part of pulse feeling for Shi-Dong-Bing of Liver Meridian of Foot Gworeum is transformed into Haeng-gan(行間) Tae-chung(太衝), among the five Su points.

본 연구에서는 창원시 강변여과수 개발사업(2단계)에서 얻어진 자료들을 이용하여 대수층의 수리전도도와 방사형집수정의 수평집수관에서 산출되는 유량과의 상관관계를 규명하고자 하였다. 연구지역인 낙동강 중하류 모래자갈층에서 수평적으로 채취한 미고결 퇴적물의 시료를 이용하여 경험식에 의한 수리전도도를 산정하였다. 여러 경험식을 이용하여 연구지역에서 수리전도도를 산정한 결과, Beyer식에 의한 수리전도도가 가장 적합한 것으로 판정되었다. 산정된 수리전도도는0.083 ~ 0.264 cm/s의 범위, 평균 0.159 cm/s로 나타내고 있어 연구지역의 대수층 특성은 모래자갈층에 투수성이 양호한 것으로 나타났다. 산정된 수리전도도와 실측자료에 의한 스크린 내 지하수의 유입속도 및 유량과의 상관관계를 분석하고자회귀분석을 실시하였다. 회귀분석 결과, 수리전도도와 지하수의 유입속도 및 유량은 약 72 %의 높은 상관관계를 가지는것으로 나타났고, 각 변수들 간에 실측자료와의 검증에서도 약 72 %가 일치하는 것으로 분석되어 선형 회귀식은 높은 적합성을 나타내었다. 본 연구의 결과로서 선형 회귀식을 이용하여 수리전도도에 의한 방사형집수정의 수평집수관에서 산출되는 유량의 추정이 가능하고, 연구지역과 유사한 대수층에서 적용이 가능할 것이라고 사료된다. This study was performed to investigate the correlation between hydraulic conductivity and the flow rate of an aquifer, with the flow rate calculated from the laterals of the radial collector well using data obtained by the development project of riverbank filtration (Second Phase) in Changwon City. The hydraulic conductivity was empirically calculated from unconsolidated sediments collected from a sandy gravel layer along the middle-to-downstream sections of the Nakdong River. The Beyer equation produced the most suitable hydraulic conductivity from the various empirical formulas employed. The calculated hydraulic conductivity ranged from 0.083 to 0.264 cm/s, with an average value of 0.159 cm/s, suggesting that the aquifer in the study area possesses a high permeability with a good distribution of sandy gravel. The relationship between the calculated hydraulic conductivity in the aquifer and the entrance velocity into the screen, the flow rate was analyzed through the linear regression analysis. From the result of regression analysis, it showed that the hydraulic conductivity and the entrance velocity into the screen and the flow rate have a linear regression equation having about 72% of the high correlation. The result of verification in the measured data between each variable showed a high suitability from being consistent with the approximately 72% in the linear regression analysis. This study demonstrates that the groundwater flow rate can be estimated within the laterals of the radial collector well using a linear regression equation, if the hydraulic conductivity of the aquifer is known. This methodology could thus be applicable to other aquifers with hydraulic conductivity and permeability parameters similar to those in the present study area.
