In this study, specific pollutant releases during the Asian monsoon season were estimated and the information was applied to the non-point pollutant sources management from two forested watersheds of the Soyang Lake. The two watersheds are part of the 2,703 km2 Soyang Lake watershed in the northern region of the Han River. The outlets of the two watersheds were respectively analyzed for continuous water quality concentration and for discharge during various single rainfall events. Statistical power function methods are utilized to compare stream discharge and pollutant flux release during the study period. Based on the monitoring data during the study period, the specific load flux method using simulated discharge was conducted and validated in the two watersheds. The model predictions corresponded well with the measured and calculated pollutant releases. The modeling approach taken in this study was found to be applicable for the two forested watersheds.

소양강물은 춘천과 서울지역 시민의 중요한 수원이다. 2006년 태풍 에위니아로 악화된 탁수현상은 예년과 달리 280일 이상 지속되었으며 이로 인하여 춘천 및 서울지역 물 공급에 차질을 빚었다. 한편 소양강 유역의 약 55%에 해당하는 고랭지밭의 토사유출이 탁수현상의 주요원인으로 꼽히며 이와 함께 무분별한 산지개간, 도로의 확포장, 임도개설 등도 탁수를 가중시키는 것으로 알려진다. 본 연구에서 2006년 6월${\sim}$2008년 8월간의 소양강 유역의 탁도, 강수량, 댐수위 등을 분석한 결과 탁도는 일 강우와 49일의 지연시간을 두고 최대의 상관성(r = 0.28)을 보였으며 특히 댐 수위와는 4일의 지연시간에 대해 탁월한 상관성(r = 0.60)을 나타냈다. 그리고 2006년과 2007년 두 차례 발생한 탁수의 지속기간과 거리별 탁도 자료를 이용하여 분석한 결과 취수원인 팔당댐에 탁수(10 NTU)가 도달하기 위한 소양강댐의 기준 탁도는 약 31 NTU로 추정되었다. 또 분석을 통해 향후 탁수발생 시 지속기간을 예측할 수 있는 지배감쇠곡선(master recession curve)을 제시하였다.

Objectives : It is told that Hyungbangsabaeksan is important to treat the Soyangin(少陽人) disease in Dongyisusebowon. Though Hyungbangsabaeksan is widely applied in Soyangin(少陽人) disease, it is difficult to understand the meaning of Hyungbangsabaeksan and also hard to use clinically. In this study, We tried to reveal the fundamental meaning of the Hyungbangsabaeksan and the indication of Hyungbangsabaeksan. Methods : We mainly studied diseases in Dongyisusebowon. The use of drug in Soyang disease(少陽病) is relatively difficult. So we firstly reviewed Mang-um disease(亡陰證) that is almost close to the Interior syndrome(裏病) and an Analogous Hak(似瘧) that is one of the interior syndrome. Based on the understanding of interior syndrome, We tried to understand Hyungbangsabaeksan in the usage of the drug in Soyang disease(少陽病). Results : We found the key point of indication of Hyungbangsabaeksan in Mang-um disease(亡陰證) of Exterior cold syndrome(表寒病) and an Analogous Hak of Interior syndrome. Also based on that, We identified characteristics of Soyang disease(少陽病). Therefore, we inferred that there are significant symptoms in Soyang disease(少陽病) that Hyungbangsabeaksan could be applied. Conclusions : Reviewing the usage of Hyungbangsabeaksan in Mang-um disease(亡陰證) and an Analogous Hak, we found that Interior syndrome is important in indication of Hyungbangsabeaksan. Also we found that Hyungbangsabeaksan is especially applied when irreversible transition of the disease can be predicted. Based on this, We concluded Hyungbangsabeaksan is preventively used in specific Soyang disease(少陽病), of which the machanism of the disease is similar.

본 연구에서는 1973년 완공된 소양호에 처음으로 발생한 녹조현상에 대하여 위성영상을 사용하여 분석하였다. 연구자료는 2023년 7월부터 약 2개월간의 광학영상 13장을 사용하였으며, 소양호에 발생한 녹조의 면적을 산출하였다. 정확한 녹조 발생 면적을 산출하기 위하여 support vector machine 알고리즘 기반으로 영상분류를 수행하였다. 그 결과 소양호의 녹조는 녹조 발생을 유발하게 한 불순물이 유입된 지점을 중심으로 발생하였다. 2023년 8월 태풍 카눈의 효과로 일시적으로 감소하는 듯 보였으나 지속된 더위로 인해 다시 녹조가 증가하였다. 본 연구결과는 소양호는 수도권 주요 수원지 중 하나로 반복적인 녹조 발생을 대비해야 하는 점을 시사한다.

1. Objective: This literary review investigates Lee Jema's clinical experiences with Soyang-type patients and their influence on his conceptualization of the Soyang physiology and pathology. 2. Methods: 1) The case reports in "Soyang constitutional type: Spleen Cold-based Exterior-Cold disease" were compared before and after the Sinchuk revision to explore the temporal change in the Sasang medical concepts. 2) The texts in Donguisusebowon (Gabo edition) and Donguisusebowon (Sasangchobongwon) were analyzed to investigate the pathological concepts appearing before the completion of the Donguisusebowon (Gabo edition). 3) The texts in Donguisusebowon (Sinchuk edition) was analyzed to investigate the pathological concepts formed between the Gabo and Sinchuk editions of Donguisusebowon. 3. Results and Conclusions: 1) Gabo edition : The Gabo edition divided the External-origin Exterior disease into Cold-dominant (Heat-moderate) and Heat-dominant (Cold-moderate) patterns and differentiated the severity of Exterior-based Exterior disease and Interior-based Interior disease into mild, moderate, severe, and critical conditions. Cold-damage Delirium disease pattern was categorized as an Interior-based Interior disease, and the treatment protocol using Baekho-tang (Baihu-tang) was established. The stool condition and bowel movement reflecting the patient's defecation habits, the prime indicator of health in the Soyang constitutional type, were emphasized on their importance. 2) Sinchuk edition: The Delirium disease pattern was moved into the Exterior-cold disease, and the treatment protocol applying Jihwangbaekho-tang (Dihuangbaihu-tang) and Hyeongbangsabaek-san (Jingfangxiebai-san), with variational usage of Gypsum, was newly established. The Seong-Jeong and basal disease patterns were suggested as important factors in treating the patients. Also, it was proposed that the symptoms and signs reflecting the condition of the life-preserving energy be assessed to understand the patient's current condition. The importance of post-acute rehabilitation and aftercare as well as the most appropriate acute-stage treatment were emphasized.

본 연구의 목적은 소양호 동물플랑크톤 군집의 장기적인 변동을 관찰하고 환경요인에 따른 영향을 알아보고자 하였다. 조사기간 동안 소양호 유역 강수량은 $705{\sim}1,779mm\;yr^{-1}$의 큰 변동을 보였으며, 이로 인한 호소의 수위변동과 함께 여름철 많은 양의 탁수가 유입되는 것으로 나타났다. 소양호 수질은 몬순기후로 인한 여름철 홍수기 탁수유입이 가장 중요한 환경요인으로 작용하였으며, 계절적 변화가 뚜렷하게 나타났다. 장기간 동안 소양호 동물플랑크톤 군집의 현존량은 2006년을 기준으로 이전과 이후로 뚜렷한 차이를 보였으며, 강우 이후 동물플랑크톤의 현존량이 급격히 증가하는 것으로 나타났다. 소양호에서 동물플랑크톤은 1차적으로 이화학적 환경요인과 양의 상관성을 보였으며, 강우 시 유입된 높은 농도의 인과 유기물 증가가 동물플랑크톤 성장에 영향을 미친 것으로 판단되었다. 그러나 소양호에서 동물플랑크톤 군집의 변동은 이화학적 환경요인으로만 설명하는 데는 한계가 있었으며, 동물플랑크톤의 생물량 증가를 먹이망 내에서 top-down과 bottom-up 효과로 설명할 수 있었다. 결과적으로 소양호 동물플랑크톤의 생물량과 군집구조는 탁수유입에 따른 영양염과 유기물 공급, 식물플랑크톤 현존량 및 종 조성 그리고 동물플랑크톤 상호작용이 주요한 결정요인으로 작용한 것으로 판단되었다.

The vertical distributions of sulfate reducing bacteria (SRB) in sediments of lakes in Korea (Lake Sihwa and Lake Soyang) and China (Lake Aha and Lake Erhai) were investigated by fluorescence in situ hybridization (FISH). SRB from sediment of Lakes of China were located to deeper layer than those in Lakes of Korea. SRB were not detected below 19 cm and 10 cm depth in sediments of Lake Sihwa and Lake Soyang, respectively. SRB numbers were, however, detected at all observed sediments in Lake Aha and Lake Erhai. In case of lakes in Korea, the proportion of SRB ranged from 2.9 to 25.6% (Lake Sihwa) and ranged from 0.6 to 7.1% (Lake Soyang). For lakes in China, the proportions of SRB were from 0.6 to 19.4% and from 2.9 to 11.2% within sediments from Lake Aha and from Lake Erhai, respectively. The high peaks of SRB numbers in sediments of all lakes were appearing at depths between 0 cm and 2 cm.
