This study was carried out to analyze characteristics of water quality and correlation among water quality parameters in Idong reservoir used for agricultural water. The pH and concentrations of DO, SS, BOD, COD, TP, Chl-a in Idong reservoir almost met the water quality standards for agricultural water, but TN concentration exceeded the water quality standards for agricultural water. All of water quality items had no significant difference between horizontal points at 95% confidence level and the Idong reservoir was possible to be treated as the single water body. As NIP ratio of the Idong reservoir is 52, TP is a limiting nutrient salt. As TN exceeds the water quality standards, it is required to preserve TP below current state to prevent water bloom by eutrophication. Therefore, reduction of phosphorus from the watershed is necessary for controlling the eutrophication of Idong reservoir.

막증식성 사구체 신염은 메산지움의 증식과 사구체 모세혈관의 비후를 동반하는 진행성 신질환으로 병리학적 소견에 따라 1, 2, 3형으로 분류할 수 있다. 이 질환은 일차성 사구체신염의 약 2%가량을 차지하는데, 대개의 경우 만성적으로 진행하는 경과를 보이며 다른 사구체신염에 비하여 신기능 소실로 진행하는 경우가 많지만 효과적인 치료법이 정립되어있지 않고 다양한 치료가 시도되고 있다. 학교 집단신체검사에서 소변검사가 포함되기 시작하면서 제1형 막증식성 사구체신염은 수차례 보고되었고 이들에 대한 조기 치료가 신질환의 진행을 늦추는데 효과적인 것으로 알려져 있는데 반해, 제2형 막증식성 사구체신염이 학교 집단신체검사에서 발견된 예는 현재까지 국내에서 보고된 바 없기에 문헌고찰과 함께 보고하는 바이다. Type II membranoproliferative glomerulonephritis (MPGN) is characterized by thickening of the glomerular basement membrane owing to electron-dense deposits on electron microscopy. We experienced a case of type II MPGN in a child presenting with proteinuria, hematuria on school urinary screening tests. He had been treated with losartan and enalapril. This is the first case report of type II MPGN detected by school urinary screening tests in Korea. Thus we report a case of 10-years-old male with type II MPGN with a review of brief literature.

The feasibility of the up- and down-flow constructed wetland was examined fur rural wastewater treatment in Korea. Many constructed wetland process was suffered from substrate clogging and high plant stresses because of long term operation. The up- and down-flow constructed wetland process used porous granule materials (charcoal pumice : SSR=10:20:70) for promoting intake rate of nutrient to plant, and especially flow type was designed continuously repeating from up-flow to down-flow. $BOD_5$ and SS was removed effectively by the process with the average removal rate being about 75% respectively. The wetland process was effective in treating nutrient as well as organic pollutant. Removal of TN and TP were more effective than other wetland system and mean effluent concentrations were approximately 7.5 and $0.4mg\;L^{-1}$ which satisfied the water quality standard for WWTPs. The treatment system did not experience any clogging or accumulations of pollutants and reduction of treatment efficiency during winter period because constructed polycarbonate glass structure prevented temperature drop. Considering stable performance and effective removal of pollutant in wastewater, low maintenance, and cost-effectiveness, the up- and down-flow constructed wetland was thought to be an effective and feasible alternative in rural area.

Water quality data for 10 years (2000~2009) from about 826 reservoirs that are operated as a agricultural water quality survey network were analyzed in order to seek water quality management plan based on physical and chemical characteristics of agricultural reservoirs. The 95% reservoirs that exceed agricultural water quality standard of Chl-a (35mg/ $m^3$) had effective water depth shallower than 5m. The reason was that the reservoirs had more inflows of nutrient salts from the watershed, bigger surface water area of weak structure to algae occurrence. As the reservoirs of effective water depth shallower than 5m cover 49% of benefited area for irrigation, it is critical for agricultural water quality management of the reservoirs. The water quality of reservoir with shallower than 5m effective water depth was worse than reservoir with deeper than 5m effective water depth. Therefore, it is desirable that effective water depth of reservoirs make more than 5m for water quality management by building the bank higher and dredging the bottom of reservoirs.

Objectives The purpose of this study is to find out the relationship between mid parental height (MPH), birth weight, current growth condition of children (height, weight, BMI, body fat percentage, bone age) and final height of the future. Methods The study was conducted with 237 children, who were 12 - 14 years old. They were analyzed to find out the relationship between MPH, birth weight, height, current weight, BMI, body fat percentage, bone age and predicted height. Results 1. As MPH was increased, height and predicted height were also increased. As MPHs in girls were increased, 'bone age - chronological age' were decreased. As MPHs in girls were increased, body fat percentages were decreased. 2. As birth weights were increased, height, weight, BMI and body fat percentages were also increased in boys. 3. As body fat percentage was increased, predicted height was decreased. As 'bone age - chronological age' was increased, predicted height was decreased. As BMI was increased, 'bone age - chronological age' was increased. As body fat percentages in boys were increased, heights were decreased. As body fat percentages in girls were increased, 'bone age - chronological age' were increased. Conclusions MPH, birth weight, current growth condition (height, weight, BMI, body fat percentage, bone age) and predicted height are correlated to each other. There are some differences between boys and girls in these relationships.

김형중 ( Hyung Joong Kim ),함종화 ( Jong Hwa Haam ),김동환 ( Dong Hwan Kim ),홍대벽 ( Dae Byuk Hong ) 한국농공학회 2011 한국농공학회 학술대회초록집 Vol.2011 No.-

인공습지의 장기 운영에 따른 수질정화효율 저하를 보완하기 위하여 조합형 인공습지 시스템을 개발하였다. 조합형 인공습지 시스템은 지표흐름 인공습지 하단에 수질정화재료를 이용한 계단형 상하흐름 인공습지(지하흐름 인공습지)를 조합하여 구성된 인공습지 시스템이다. 계단형 상하흐름 인공습지는 폭 1.4m × 길이 5.6m × 높이 1m를 4열 설치하고, 그 속에 각각 바이오 세라믹, 활성탄, 복합여재, 제강슬래그를 충진하였다. 유기물 지표인 COD의 경우 유입수는 평균 8.43 mg/L로 농업용수 수질기준을 초과하였다. 그러나 인공습지+활성탄 시스템은 평균 2.17 mg/L로 낮아져 농업용수 수질기준을 만족할 뿐만 아니라 74.24%의 높은 제거율을 보였다. 다음으로 인공습지+제강슬레그 시스템이 평균 6.43 mg/L, 인공습지+활성탄+화산석 시스템이 평균 7.29 mg/L로 농업용수 수질기준을 만족하고, 각각 23.73%, 13.56%의 정화효율을 보였다. 반면, 인공습지+세라믹 시스템은 평균 8.24 mg/L로 수질기준을 초과하고, 2.20%의 낮은 정화효율을 보였다. 분산분석결과도 95% 신뢰수준에서 p=1.159E-05로서 시스템별로 유의한 차이가 있는 것으로 나타났다. TN은 유입수의 농도가 평균 3.19 mg/L로서 농업용수 수질기준을 초과하였다. 반면, 인공습지+활성탄 시스템은 평균 0.27 mg/L로 낮아져 농업용수 수질기준 이하를 만족하였다. 인공습지+제강슬레그 시스템과 인공습지+활성탄+화산석 시스템도 처리수의 TN농도가 각각 평균 0.95 mg/L, 0.96 mg/L로 낮아져 대부분 수질기준을 만족하는 경향을 보였다. 그러나 인공습지+세라믹 시스템은 평균 1.06 mg/L로 낮아지기는 하였으나 수질기준을 초과하는 경우가 많았다. 이 때 각 시스템의 수질정화효율은 인공습지+활성탄 시스템이 91.48%, 인공습지+제강슬레그 시스템이 70.34%, 인공습지+활성탄+화산석 시스템이 70.04%, 인공습지+세라믹 시스템이 66.94%의 높은 값을 보였다. TP는 유입수가 평균 0.21 mg/L로서 모두 호소의 농업용수 수질기준인 0.1 mg/L보다 높았다. 반면, 인공습지+제강슬래그 시스템의 경우는 유출수가 평균 0.02 mg/L로 낮아져 90.96%의 매우 높은 정화효율을 보였을 뿐만 아니라 모두 농업용수 수질기준을 만족하였다. 인공습지+활성탄 시스템 유출수도 평균 0.06 mg/L를 나타내면서 모두 농업용수 수질기준 이하를 만족하였고, 이때 TP정화효율은 69.69%의 높은 값을 나타냈다. 인공습지+활성탄+화산석 시스템은 유출수가 평균 0.12 mg/L로서 45.12%의 정화효율을 보였으나 농업용수 수질기준을 만족하지 못하는 경우가 있었다. 인공습지+세라믹 시스템 유출수의 경우도 평균 0.13 mg/L로서 유입수에 비해 낮아져 39.31%의 정화효율을 나타냈다. 이와 같이 조합형 인공습지 시스템은 인공습지의 장기 운영에 따른 TP와 COD 처리효율의 감소현상을 보완하기 위한 시스템으로 도입이 가능한 것으로 판단된다. 특히 활성탄과 제강슬래그를 이용한 인공습지 시스템이 매우 효과가 높은 것을 알 수 있었다.
