The important changes in water environment management in Korea can be summarized as the enactment of Act on the Integrated Control of Pollutant-Discharging Facilities. Therefore water quality impact assessment should be reexamined and be revised. This study examines the present water quality impact assessment items (permissible discharge limits, standards for effluent water quality including Total Pollutant Load Management System) and considers the land use regulation for water quality conservation and NVZs(Nitrate Vulnerable Zones of EU and England). It also considers lately adopted standards(maximum discharge standards, permissible discharge standards, and marginal discharge standards etc) based on Act on the Integrated Control of Pollutant-Discharging Facilities and then compares Korean BAT and its counterpart control technology of U.S.A. And it also compares the items of water quality impact assessment with those of Integrated Control of Pollutant-Discharging Facilities, based on EIS reporting items. This study suggests five improvement measures for water quality impact assessment. First reflection of discharge impact analysis on impact prediction and assessment, second reflection of permissible discharge standards on agreed standards in the EIA procedure, third, reflection of diversified BAT on mitigation measures in the EIA procedure, forth introduction of land use regulation such as NVZs, finally strengthening linkage between water quality items and land use items etc.

남·북한강 상류 수계에는 만대지구, 가아지구, 자운지구, 도암호유역, 골지천유역, 대기지구 등 총 6개의 비점오염원관리지역이 지정되어 있으며, 비점오염원관리를 위한 관리대책 및 시행계획에 따라 지속적으로 비점오염저감시설이 설치·운영되고 있다. 그러나, 기후변화에 따른 집중호우 등의 원인으로 뚜렷한 비점오염 저감효과가 나타나지 않고 있으며, 개별 비점오염 저감시설의 명확한 저감효율이 정량화되지 않아 탁수저감 기여도 및 효율성 평가 시 한계가 있다. 따라서 본 연구에서는 문헌연구를 통하여 비점오염저감시설별 저감효율 제시가 미흡하였던 시설 중 돌망태, 식생토낭에 대해 실험을 진행하였다. 저감효율 평가를 위해 경사도 3%, 사면 폭 4 m, 사면길이 22 m의 시험포를 조성하였다. 강우시 발생하는 유출수를 대조구와 비교하였으며, 영농시기를 고려하여 영농작업을 병행하여 실시하였다. 제거효율법을 통한 저감효율 산정 결과 돌망태와 식생토낭의 SS항목은 80.5%와 73.7%로 저감효율이 가장 높은 것으로 나타났으며, BOD는 71.2%, 60.2%, T-N은 70.5%, 64.7%, T-P는 63.7%, 63.1%로 나타났다. TOC는 46.8%, 38.8%로 다른 항목에 비해 상대적으로 낮은 저감효율이 나타났다. 부하량합산법을 통한 저감효율 산정 결과 돌망태와 식생토낭의 T-N 항목은 78.6%와 70.8%로 저감효율이 가장 높은 것으로 나타났으며, BOD는 77.5%, 65.4%, SS는 76.7%, 67.8%, T-P는 68.4%, 63.7%로 나타났다. TOC는 62.7%, 44.6%로 시설별 뚜렷한 차이가 나타났다. 제거효율법과 부하량합산법을 이용하여 저감효율을 분석한 결과 모든 항목에서 40%이상의 저감효율이 나타났으며, 돌망태가 식생토낭에 비해 저감효과가 좋은 것으로 분석되었다. 경사면의 흙탕물 저감을 위해서는 비점오염저감시설의 설치가 우선되어지나, 탁수저감 기여도 및 저감효율 제시를 위한 정량화는 장기간의 모니터링이 필요하기 때문에 지속적인 모니터링을 통한 효율평가가 이루어져야 할 것으로 판단되며, 본 연구 결과는 향후 비점오염저감시설 설치에 따른 유역 내 오염물질 발생 모의를 위한 모델링의 기초차료로 활용될 수 있을 것으로 기대된다.

Riverfront facilities are river space facilities used by citizens for the rest and convenience. Recently, although the importance of efficient maintenance of riverfront facilities is increasing, damaging facilities cases are increasing due to frequent floods. Currently, the inspections and diagnosis of river space facilities are limited to the main flood control facilities. And the standards for the maintenance and management of the riverfront facilities are insufficient. Utilization survey, which is the standard for managing river space facilities, is also inefficient in terms of manpower consumption and economic feasibility. This study uses mobile big data to classify river usage and conducts a survey for usability of river facilities to derive economic evaluation for usage performance. In the future, if economical method system that considers safety, usability, and durability is conducted and demanding analysis for each convenience facility is evaluated, it is expected that the efficient maintenance of riverfront facilities is perfomed better and the use of rivers by citizens will further increase.

As the law on the private sector investment in social infrastructure was amended in January of 2005, the government is aggressively promoting BTL projects but many trials and errors and problems are occurring. Especially, the Value-For-Money evaluation conducted by the responsible agencies to judge the appropriateness of the project found there was a conspicuous difference between the computed cost and the final contract sum. Accordingly, this study is aimed to grasp the problems in the current Value-For-Money evaluation and to improve it in order to proceed with BTL projects efficiently. To achieve this, through a relative comparison to the final contract sum, a clear standard for the items of Value-For-Money evaluation was presented and thus, a model that can ensure accuracy in computing the Value-For-Money was established so that a delay in negotiations can be avoided. If the Value-For-Money evaluation established in this study is used in assessing the appropriateness of unit prices for BTL projects for education facilities, a reasonable result can be expected to be drawn in selection and negotiations with contractors, and maintenance and Post-Operation-Evaluation(POE) of education facilities as well.

Leading waste disposal countries, such as Sweden, Switzerland, and the United Kingdom, conduct safety assessments across all stages of High-Level Radioactive Waste Deep Geological Disposal Facilities-from planning and site selection to construction, operation, closure, and post-closure management. As safety assessments are repeatedly performed at each stage, generating vast amounts of diverse data over extended periods, it is essential to construct a database for safety assessment and establish a data management system. In this study, the safety assessment data management systems of leading countries, were analyzed, categorizing them into 1) input and reference data for safety assessments, 2) guidelines for data management, 3) organizational structures for data management, and 4) computer systems for data management. While each country exhibited differences in specific aspects, commonalities included the classification of safety assessment input data based on disposal system components, the establishment of organizations to supply, use, and manage this data, and the implementation of quality management systems guided by instructions and manuals. These cases highlight the importance of data management systems and document management systems for securing the safety and enhancing the reliability of High-Level Radioactive Waste Disposal Facilities. To achieve this, the classification of input data that can be flexibly and effectively utilized, ensuring the consistency and traceability of input data, and establishing a quality management system for input data and document management are necessary.

Over the past decade, urban regeneration projects have been actively promoted nationwide in South Korea, leading to the establishment of numerous community facilities aimed at fostering community engagement and revitalization. Recently, the need for diagnostic tools to provide appropriate support and guidance for the sustainable operation of these facilities has been increasingly emphasized. However, a comprehensive manual or nationwide standard approach remains lacking. As such, this study aims to propose evaluation criteria and their application methods for the periodic operational assessment of those facilities. First, through a review of previous studies, candidate indicators were identified. After that, preliminary indicators and frameworks were determined through expert consultations, followed by surveys conducted with 65 experts to finalize the evaluation indicators. The survey results highlighted the importance of 'Value Creation (VC)' and 'Operation Management (OM)' as key aspects of facility evaluation. In assessing VC, key factors include enhancing community vitality, strengthening local capacity, providing tailored functions for the community, and contributing to the local economy. In constructing OM, the focus lies on operational system, financial management, operational personnel, and economic viability and sustainability. This study proposes an evaluation framework that includes the final evaluation indicators and available data sources for each indicator, and a pilot test was conducted to verify its applicability. Moreover, the study suggests directions for utilizing the evaluation criteria and methods for applying indicators tailored to the characteristics of individual facilities.
