우리는 지금 수자원관리의 새로운 패러다임을 맞이하고 있다. 이는 수자원과 관련된 환경의 변화 때문일 것이다. 소비자들은 자신들이 원하는 때에 원하는 만큼 물을 확보하고 싶어 하지만 절대적인 수요량의 증가는 이 같은 요구를 충족하지 못하고 있다. 물과 관련된 사회적인 분쟁이 증가하고 있고 결과적으로 수자원정책과 이에 대한 연구가 수자원관리의 가장 중요한 요소로 부각되고 있는 것이다. 우리나라도 최근 수자원정책에 대한 몇 몇 연구가 있었으나 다양성이 강조되어야 하는 정책연구가 지나치게 일정부문에 국한되어 왔다. 본 연구는 우리나라 수자원정책 연구에 대한 평가를 토대로 향후 방향에 대한 제언을 하였다.

Frequent hydro-meteorological events caused by global climate change and human exacerbate activities, make the water resource problem more complicated. The increasing speed urbanization brings a significant impact on the city flood control and security, water supply safety, water ecological security, water environment safety and the water engineering security in China, and puts forward higher requirements to urban water integrated management, undoubtedly which become the biggest obstacle for water ecological civilization construction, thus urgent requiring an advanced methods to enhance the effectiveness of the water integrated management. The other fields of smart ideas point out a development path for water resource development. The construction demand of smart water resource is expounded in the paper, combining the philosophy of modern Internet of things with the application of cloud computing technology. The concept of smart water resource is analyzed, the connotation characteristics of smart water resource is extracted, and the general model of smart water resource is refined. Then, the frame structure of smart water resource is put forward. The connotation and the overall framework of the smart water resource represent a higher level of water resource informationization development and provide a comprehensive scientific and technological support to transform water resource management from an extensive, passive, static, branch and traditional management to a fine, active, dynamic, collaborative and modern management.

The impervious area on the surface of urban area has been increased as buildings and artificial land cover have continually been increased. Urban development has gradually decreased the green zone in downtown and alienated the city from the natural environment on outskirt area devastating the natural ecosystem. There arise the environmental problems to urban area including urban heat island phenomenon, urban flood, air pollution and urban desertification. As one of urban plans to solve such problems, green roof system is attracting attentions. The purpose of this study was to investigate flood discharge and heat reduction effect according to the green roof system and to quantify effect by analyzing through simulation water and heat cycle before and after green roof system. For the analysis, Distributed hydrologic model, WEP (Water and Energy transfer Processes) and WEP+ model were used. WEP was developed by Dr. Jia, the Public Works Research Institute in Japan (Jia et al., 2005), which can simulate water and heat cycle of an urban area with complex land uses including calculation of spatial and temporal distributions of water and heat cycle components. The WEP+ is a visualization and analysis system for the WEP model developed by Korea Institute of Construction Technology (KICT).

Objectives : Onion (AlliumcepaL.) is one of the richest sources of flavonoids in human diet. In this study, we studied the effects of onion peel water extract (OPE) on the blood lipid profiles and glucose in rats. Methods : The experimental groups were divided with 5 groups (n = 6) of SD rats: normal diet + distilled water (NC), high-fat diet + Quercetin (PC), high-fat diet + onion peel water extract 4 mg/kg (OPE-4), high-fat diet + onion peel water extract 20 mg/kg (OPE-20), high-fat diet + onion peel water extract 100 mg/kg (OPE-100). Results : The liver fat showed significantly lower weights and size in the OPE-100 group as compared with NC group (p<0.05), The epididymal fat and retroperitoneal fat showed significantly lower weights and sizes in the OPE-4 and OPE-20 group as compared with NC group (p<0.05). The serum levels of total cholesterol, LDL cholesterol and triglyceride were significantly lower in the OPE-4 and OPE-20 group as compared with NC group (p<0.05). The OPE-4 and OPE-20 group showed higher HDL cholesterol concentration than NC group (p<0.05). Atherogenic index of OPE-4 and OPE-20 group was significantly lower in as compared with NC group (p<0.05). The serum levels of glucose significantly lower in the OPE-20 group as compared with NC group (p<0.05). Conclusions : In these results, we suggests that onion peel water extracts supplementation can reduces the serum lipid components and improves the lipid metabolism in hyperlipidemic SD rat induced with a high-fat diet.

Korea Water Resource Corporation is planning the active application on the New-Renewable energy enterprise at Si-Wha region which is located in Kyonggi-Do, builded up as the national policy enterprise and also currently carrying out a tidal electric power station construction. This research is considered of geography circumstance of the region. We are to analyze a wind power resources application feasibility in the side of economical efficiency and see simultaneously application of the wind power system also.

기후변화 적응전략 수립에 있어 정책적 패러다임이 과거 구조적 대책에서 위험관리로 변화하고 있으며, 지역 내 다양한 이해관계자의 참여와 협력을 바탕으로 하는 수자원 거버넌스의 구축은 기후변화 적응전략 마련의 핵심이라고 할 수 있다. 본 연구에서는 국내 및 OECD 주요국들의 물관리 정책과 수자원 거버넌스의 발전 과정 및 현황을 검토하여 국내 수자원 거버넌스의 한계점을 파악하고, 효과적인 기후변화 적응을 위한 국내 수자원 거버넌스의 개선방안을 모색하고자 한다.

본 연구에서는 물 사용관련 주요 지표인 1인1일 급수량을 이용하여 수요관리 추진 결과 분석 및 절감량을 산정하고, 수요관리를 통하여 발생하는 절감량을 물 수급전망에 연계할 수 있는 시스템을 개발하였다. 1인1일 급수량 분석결과 상수도 여건이 열악한 지자체는 상수도 보급 개선이 선행되어야 하며, 장래용수수요량 추정시에도 이를 고려하여야 할 것으로 판단된다. 금강권역을 대상으로 수요관리 절감량을 산정하고 K-WEAP (Korea-Water Evaluation And Planning System)을 이용하여 물수지분석을 수행한 결과 하천유량 변화 및 지하수와 저수지저수량 증가를 확인하였으며, 이는 다른 용도로 활용 가능하다고 판단된다.

In Korea while the dam or reservoir is an important water resource, the value of this water resource is deteriorating by thermal-induced stratification. To ameliorate the water quality of reservoir by breaking stratification the use of air diffuser system is now widespread in Korea. According to the previous research, dynamics of bubble plume and destratification efficiency depended upon two dimensionless groupings; Mh and Pn suggested by Asaeda et al (1993). However, these two variables only include Q, N, H, g, u. and installed Boryeong reservior in appropriate width of water aeration, air dose and number of installations after calculating by applying these figures. This paper is performed to find out effect analysis about water aeration improvement to break thermal stratification.
