House management is very important in water resource protection in order to provide sustainable drinking water for about four millions population in northern Taiwan. House management can be a simple job that can be done without any ingredient of remote sensing or geographic information systems. Remote sensing and GIS integration for house management can provide more efficient management prescription when land use enforcement, soil and water conservation, sewage management, garbage collection, and reforestation have to be managed simultaneously. The objective of this paper was to integrate remote sensing and GIS to manage houses in a water resource protection district. More than four thousand houses have been surveyed and created as a house data base. Site map of every single house and very detail information consisting of address, ownership, date of creation, building materials, acreages floor by floor, parcel information, and types of house condition. Some houses have their photos in different directions. One house has its own card consists these information and these attributes were created into a house data base. Site maps of all houses were created with the same coordinates system as parcel maps, topographic maps, sewage maps, and city planning maps. Visual Basic.NET, Visual C#.NET have been implemented to develop computer programs for house information inquiry and maps overlay among house maps and other GIS map layers. Remote sensing techniques have been implemented to generate the background information of a single house in the past 15 years. Digital orthophoto maps at a scale of 1:5000 overlay with house site maps are very useful in determination of a house was there or not for a given year. Satellite images if their resolutions good enough are also very useful in this type of daily government operations. The developed house management systems can work with commercial GIS software such as ArcView and ArcPad. Remote sensing provided image information of a single house whether it was there or not in a given year. GIS provided overlay and inquiry functions to automatically extract attributes of a given house by ownership, address, and so on when certain house management prescriptions have to be made by government agency. File format is the key component that makes remote sensing and GIS integration smoothly. The developed house management systems are user friendly and can be modified to meet needs encountered in a single task of a government technician.

Issues and problems in formulating South Korea's water resources policy are discussed in terms of water quantity and quality. South Korean needs both water conservation and water supply capability for the growing population and economic activities. The government has attempted to build more large-scale dams to store and supply water for residential, farming and industrial uses, but the environmentalists who emphasize conservation and environmental protection oppose the government. The environmentalists are popular among the general public. Water quality has been deteriorating from point- ad non-point sources. urban and farm runoffs are serious pollutants. All want by preserve water quality. There is no dispute on this matter between the government and the environmentalists. Money is hard to come by to preserve water quality. Economic and financial crises and no self-sufficient local governments' revenue structure are pessimistic. Basic survey on water resources, hydrology and hydraulic is badly needed for the future water resources planning.

최근 우리 사회에서 빈번하게 목격되는 환경이념과 개발이념 간의 갈등은 대체로 지역의 문제로써 표출되는데, 팔당 상수원 보호구역의 경우도 마찬가지이다. 자연자원의 개발을 통해 지역발전을 도모하고자 하는 지역주민들과 수도권 전체의 공익을 위한 맑은 물 확보 차원의 정부의 노력이 상충되고 있는 현장인 것이다. 더욱이 환경보호가 핵심키워드로 인식되고 있는 작금의 상황은 중앙의 환경단체들이 정부 편에 서서 지배담론을 강화시켜 줌으로써 생존권 화보를 위한 지역주민들의 저항담론을 약화시키고 있고, 따라서 극한 대립의 상황에까지 이르게 하였다. 이러한 갈등의 구도 속에서 매우 인상적인 중재적 역할을 수행하고 있는 것이 바로 유기농업운동이다. 이는 정부와 지역의 첨예한 대림을 완화시키고, 소위 윈-윈(win-win) 전략의 수립이 가능한 방향으로 지역주민들을 설득해가고 있다. 이는 또한 "지속가능한 발전", 혹은 "지탱가능성" 이념을 충족시킬 수 있는 하나의 대안으로써 이 지역에서 뿌리를 내려가고 있다. 환경규제에 맞서서 싸우고 있는 지역에서 오히려 혁명적인 친환경적 지역발전 정책들이 추진되고 있다는 본 지역에서의 상황이 다소는 역설적으로 들릴 수 있으나, 이는 우리나라의 농촌지역에서 앞으로도 계속 겪게 될 환경보존과 지역발전의 대립 구도 해결에 있어서 매우 중요한 방향타가 될 수 있을 것이다.

Objectives: Potential environmental risks caused by chemicals that could be released from a recycled plastic product were assessed using a screening risk assessment procedure for chemicals in recycled products. Methods: Plastic slope protection blocks manufactured from recycled plastics were chosen as model recycled products. Ecological risks caused by four model chemicals - di-(2-ethylhexyl) phthalate (DEHP), diisononyl phthalate (DINP), cadmium (Cd), and lead (Pb)-were assessed. Two exposure models were built for soil below the block and a hypothetic stream receiving runoff water. Based on the predicted no-effect concentrations for the selected chemicals and exposure scenarios, the allowable leaching rates from and the allowable contents in the recycled plastic blocks were also derived. Results: Environmental risks posed by slope protection blocks were much higher in the soil compartment than in the hypothetic stream. The allowable concentrations in leachate were $1.0{\times}10^{-4}$, $1.2{\times}10^{-5}$, $9.5{\times}10^{-3}$, and $5.3{\times}10^{-3}mg/L$ for DEHP, DINP, Cd, and Pb, respectively. The allowable contents in the recycled products were $5.2{\times}10^{-3}$, $6.0{\times}10^{-4}$, $5.0{\times}10^{-1}$, and $2.7{\times}10^{-1}mg/kg$ for DEHP, DINP, Cd, and Pb, respectively. Conclusions: A systematic ecological risk assessment approach for slope protection blocks would be useful for regulatory decisions for setting the allowable emission rates of chemical contaminants, although the method needs refinement.

The aim of this study is to explore the possibility utilizing Rhododedron brachycarpum as a new natural dye resource. It was dyed in silk fabric according to different dyeing conditions such as dye concentration, dye bath temperature, dyeing time and dye bath pH. The effect of the mordanting conditions were estimated as dyeability and color changes. Additionally, the colorfastness, antibacterial property, ultraviolet protection properties of the dyed and mordanted silk fabrics were examined. The water-soluble dye of Rhododedron brachycarpum extracted with distilled water was expressed as Yellow Red color. The dye-abilities of silk generally increased depending on the increasing values of dye concentration, dye bath temperature and dyeing duration. The highest K/S values were obtained at a dye concentration of 100% (v/v), a dye bath temperature of $90^{\circ}C$, a dyeing duration 120 minutes and a dyeing of pH 2. The light fastness of dyed and Cu mordanted silk fabrics were found to be 4 grade while Al, Fe mordanted silk fabrics were found to be 2~3 grade. The dry cleaning and rubbing fastness were excellent or good. The fade of washing fastness was not good, however, the stain of washing fastness was excellent. The dyed and Al, Cu mordanted silk fabrics indicated 99.9% reduction rate. The dyed and the mordanted fabrics showed very good ultraviolet protection factors.

본 연구에서는 (1) 선진외국 및 기타국가의 농업용수 수질기준을 검토하고 (2) 선진외국과 국내의 농업용수 수질기준을 항목별로 심층 비교 분석하여, 현행 농업용수 수질기준의 적정성을 평가하였다. 또한 (3) 국내 농업용수 수질기준의 문제점을 파악하고 추가로 기준설정이 요구되는 수질기준 항목을 도출하였다. 우리나라의 농업용수 수질기준은 따로 마련되어 있는 것이 아니라, 수질환경기준의 4등급에 해당하는데, 이는 관리목적의 기준으로 이수목적의 농업용수로 필요한 항목들이 누락되어 있는 실정이다. 예를 들어 캐나다의 경우 농약과 비료에 의한 오염 등을 고려하여 관개용수 수질기준을 제시하고 있으며 일본의 경우 우리나라와 달리 EC, Zn, 그리고 Cu항목을 설정해 두고 있다. FAO에서도 주요항목으로 염도와 토양 침투율 그리고 특정이온의 독성에 대해 제시하고 있으며 중국의 경우 벼에 대한 농업용수 수질기준을 따로 제시하고 있는 실정이다. 국내 농업용수 수질기준의 추가항목 필요성은 수질환경기준의 8항목과 사람의 건강보호항목 9항목으로 나누어 세밀하게 검토한 결과, 국내 농업용수 수질기준에 추가되어야 할 수질항목으로 나트륨, 전기전도도, 미생물항목. 그리고 5개의 미량원소 (염소, 붕소, 구리, 철, 아연)가 제안되었다. 전기전도도 (EC) 는 염도의 지표로 식물뿌리 주변에 염농도가 높으면 수분결핍과 이온 독성을 나타낸다. 하수처리수를 재이용하여 농업용수로 이용할 경우 분변성 오염은 공중위생상 문제가 되며 병원성 미생물의 공존가능성을 시사하기 때문에 미생물항목이 필요하다. 또한, 염소, 붕소, 구리, 철, 아연의 5개의 원소는 이미 선진국에서는 기준설정이 되어 있는 수질항목들로, 식물생장에 필수원소들이지만 일정량 이상이 되면 식물독성을 유발하는 원소로 제시되었다. 우리나라의 농업용수 수질기준이 농작물을 보호하고, 나아가 인체건강을 고려하는 실질적인 이수목적의 기준이 되기 위해서는 추가로 제안된 수질항목들에 대한 기준이 선정된 필요가 있는 것으로 사료된다.

The purpose of the study for the development of the technologies of water quality monitoring and contamination protection at water resource aquifer is to secure the groundwater as potable water resources. The results of water analysis as a basis of potable water criteria showed that 30 groundwater samples among 138 samples of small water supply system (21.7%) were exceeded the water criteria. The concentrations of Cl, $NO_3$ and Na for granite area are higher than those of gneiss and metasedimentary rocks of Ogcheon belt area and they are caused by the high vulnerability of groundwater at granite region where the residential area and cultivated land are concentrated. The spatial distribution of components indicated the close relationships between water quality and geology, land use, and topography. The multivariate statistical results showed that the water samples are divided into three groups by geology.
