미국 뉴저지주 매차포닉강의 수질 모델 연구 : 오염 부하량 분석
박선순,크리스토퍼 유클린 江原大學校 附設 環境硏究所 1990 環境硏究 Vol.7 No.-
보정 및 검정 완료된 수질 모델을 이용하여 폐수 처리장 확장에 따른 안정 오염 부하량 분석이 실시되었다. 분석한 수질 현상은 생활 하수 유입 하천에서 일반적으로 나타나는 세가지 주요 현상 즉, 1) 용존산소, 2) 암모니아 독성, 그리고 3) 부영양화이다. 여름과 겨울에서의 갈수유량(7Q10)과 이때 나타나는 온도를 예측시 하천 임계 조건으로 가정하였다. 이 예측은 하천 수질에 악영향을 미치지 않는 방류수 수질 기준을 여름과 겨울에서 각각 결정하였으며 Utilizing the constructed water quality model, the waste load allocation analysis was performed for the purpose expansion of wastewater treatment plant. The projected water quality parameters were three major aspects in the streams of municipal wastewater effluents: 1) dissolved oxygen level, 2) ammonia toxicity, and 3) nutrient/eutrophication. The 7Q10 flow rates for both summer and winter periods and the temperatures associated with these periods were used as the critical stream conditions The projections determined the acceptable treatment levels for the purposed discharges during winter and summer periods, including dissolved oxygen, biochemical oxygen demand, ammonia nitrogen, total kjeldahl nitrogen, total organic phosphorus, total dissolved phosphorus, pH, and alkalinity.

Osteoporosis is a metabolic bone disease associated with an imbalance of bone remodeling. Osteoporosis is characterized by decreased bone mass and increased bone fractures. In this study, we investigated the effects of horse bone extracts (HBEs) in vivo. Horse bone was extracted with 80% alcohol (HBE-A) at 100oC or water (HBE-W) at 120oC. Animal model of postmenopausal osteoporosis was used, in which osteoporosis was induced by ovariectomy of female S.D. rats (female rats were divided into 5 groups), and HBEs were administered to ovariectomized rats every day for 8 weeks. After 8 weeks, the rats were sacrificed and the following osteoporotic factors were measured: body weight, bone mineral density (BMD), uterine/body weight ratio, serum estradiol (E2), and serum alkaline phosphatase (ALP). The results showed that the administration of HBE-W decreased the changes of body weight in ovariectomized rats. HBE-W increased the uterine/body weight ratio and BMD.
