  • Objectives: The main purpose of this review is to introduce the current status of environmental health indicators of Korea and to share our experience of the developmental process of Korean version of environmental health indicators. Methods: This paper describes 1) the background of environmental health indicators; 2) the ways how we developed environmental health indicators of Korea; 3) the current status of selected indicators; and 4) suggestions for the further policy development. Results: The 6-year long project for the development of environmental health indicator systems in Korea could provide outputs on three major distinct aspects on the indicator issues. Firstly, we have developed the rational process/manual so that the government can select and advocate the potential indicators with a relatively objective manner. Secondly, we have suggested the potential candidate indicators which can be implemented immediately. We also pooled all indicators in order to evaluate the summary index which we expect to tell the status of environmental health. Third, we provided suggestions on the further utilization of this indicator system. Conclusion: The mission of environmental health policy is to resolve the public health problems occurring because of hazardous environment. In order to identify the environmental determinants of the community health problems and to evaluate the effectiveness of the policy implemented, these environmental indicators can be used. Therefore, the government should implement this ready-prepared system of environmental health indicators.

  • In this paper, we study on a modified mesh generation method based on the pollution error estimate. This method is designed for the control of the pollution error in any patch of elements of interest. It is a well-known fact that the pollution error estimates are much more than the local one. Reliable a posteriori error estimation is possible by controlling the pollution error in the patch through proper design of the mesh outside the patch. This design is possible by equally distributing the pollution error indicators over the mesh outside the patch. The conventional feedback pollution-adaptive mesh generation algorithm needs many iterations. Therefore, the solution time is significant. But we use the remeshing scheme in the proposed method. We will also show that the pollution error reduces less than the local error.

  • 지표를 활용한 대기오염 취약성 평가에서는 지표의 선정과 함께 지표별 가중치 결정이 중요한 문제이다. 본 연구는 전국 249개 시군구를 대상으로 엔트로피 가중치 산정법을 활용하여 오존을 중심으로 한 대기오염 취약성을 평가하고, 엔트로피 가중치 방법론의 활용가능성을 검토하였다. 연구방법은 대기오염 취약성 지표를 선정하고 이들을 표준화하고, 엔트로피를 이용한 가중치를 적용하여 취약성을 평가하는 방식을 활용하였다. 노출 지표는 기상요인과 대기오염요인을 고려하였고, 민감도는 취약대상과 취약환경요인을, 지자체별 적응능력은 지역의 사회 경제적 요소, 보건의료요인, 대기관리 요인을 적용하였다. 취약성 평가 결과는 단순합산의 경우 화성시, 광진구, 김포시, 광주시, 군포시 순으로 취약성이 높게 나타났으며, 취약성-탄력성 지표(VRI) 방식도 단순합산 결과와 유사한 취약지역 공간 분포 패턴을 나타내었다. 본 연구에서 제시한 엔트로피 가중치를 이용한 대기오염 취약성 평가는 자료에 기반한 객관적인 취약성 평가로 불확실성을 동반하는 기후변화와 대기오염 취약성 평가에 활용가치가 높을 것으로 보인다. 또한 취약성 평가결과는 지자체별 특성이 반영된 것으로 세부적인 분석을 통해 지역 맞춤형 정책수립에 활용될 수 있다.

  • It is one of the most critical steps identifying impaired waterbodies exactly in the selection of target water quality indicators for the management of Total Maximum Daily Loads (TMDLs). Excess ratio and excess level were applied and analyzed by the stream zone basis in order to evaluate water impairment for Nakdong, Geum, Youngsan and Seomjin rivers. Each river basin was divided into stream zones in the light of its watershed and waterbody characteristics. Selected water quality parameters discussed in this study were pH, DO, BOD, COD, SS, T-P, T-Coli and F-Coli. The excess ratios of the water quality parameters were used to discriminate water bodies that did not meet water quality standards. The excess levels were used to classify the degradation of water quality. The excess ratios and the excess levels to the water quality criteria of the medium influence areas were used for each stream zone. The results indicate that the excess ratios and the excess levels are varied on the stream zone in each river basin. Three parameters, pH, DO and SS, met water quality standards in all stream zones. The other five parameters indicated very high excess ratios in most waterbodies, and especially T-P and T-Coli revealed to be very high excess levels in some waterbodies. These parameters could be considered as major target indicators for the management of TMDLs.

  • Saemangeum reclamation project was started in 1991 with the purpose of eco-friendly reclamation, but without clear definition of eco-friendliness. This study was carried out to find out the environmental indicators to define and evaluate the eco-friendliness of Saemangeum project. The methodology to identify the indicators included the analysis of similar reclamation projects, professional discussions, and Delphi survey. The eco-friendly indicators are theoretically based on the five elements of eco-friendliness; 1) resource consumption, 2) energy consumption, 3) pollution emission, 4) bio-diversity, 5) social amenity. The 69 indicators were explained in detail for the convenient use of the indicators by the potential users. The 69 indicators were classified into three categories such as pre-evaluation, process evaluation, and post-evaluation. In terms of spatial consideration, the 69 indicators were classified into two categories such as direct influence area and indirect influence area. Also the 69 indicators were classified into 7 categories: 1) sea, 2) lake, 3) agricultural land use, 4) industrial land use, 5) residential land use, 6) tourism land use, and 7) environmental land use. Twenty core indicators were selected from the 69 indicators by surveying the importance of each indicator. The core indicators are recommended in case of time and budget strain. When there are few quantitative data accumulated for the reclamation project, 5 macro indicators are recommended to be used. Macro indicators are qualitative in nature, and may be used in order to evaluate the overall eco-friendliness of a reclamation project.

  • For monitoring the fecal pollution at Nak-Dong River, one of the eutrophicated rivers, the differences between total coliforms (TC) and fecal coliforms (FC) using both of membrane filtration (MF)/MPN method, and also fecal streptococcus (FS) by MF-method was investigated. To evaluate the correlation between TC, FC, and FS statistical analyses were performed by using Minitab. And a part of the presumptive TC/FC and background colonies was purified and identified using API 20E kit (Biomeriux). As results, most (89%) of presumptive FC by MF was identified as Escherichia coli while only 14% (MPN) and 11% (MF) of TC were identified as E. coli. Furthermore, FC by MF was correlated significantly with other fecal indicators (TC/FS by MF and FC by MPN), while TC by MPN was not correlated with any other indicators. Thus, the detection of FC by MF-method may be the most reasonable for monitoring the fecal pollution.

  • The objective of this study was to investigate non-point sources (NPS) pollution and prioritize management areas affected by NPS pollution in the Saemangeum Watershed. AHP (Analytical Hierarchy Process) technique was selected to prioritize sub-watersheds for effectively managing NPS pollution in this study areas. Generation properties of NPS pollution, discharge properties of NPS pollution, and runoff properties of NPS pollution were selected and set for AHP. Weighted descriptors including indicators like numbers of livestock, land- and livestock-system loads, rainfall, and impervious area ratio were generalized from 0 to 1 and multiply each index based on screened 17 survey data. The results were visualized as maps which enable resource managers to identify sub-watersheds for effective improving water quality. The sub-watersheds located in Gongdeok-Myeon, Yongji-Myeon, Hwangsan-Myeon of Gimje-Si were selected for managing NPS pollution control areas. This result presented that these sub-watershed are more affected by the pollution from livestock-system than from land-system. The finding from this study can be used to screen sub-watersheds that need further assessment by managers and decision-makers within the study area.

  • To effective a watershed management, it is necessary to have one or more quantitative measures that can be used to evaluate the relationship between pollutant sources and their impact on water quality. Such measurable quantities are termed indicators. Once an indicator has been selected, a target value for that indicator must be established that seek to distinguish between the impaired and unimpaired state of the waterbody. Various factors will be considered for the selection of an appropriate watershed management indicator. For example, available data, application, management conditions, cost, etc. This paper lists various factors that should be addressed in choosing a watershed management indicators and investigates applicable indicators during watershed management period.
