Using materials recovered from the waste stream instead of virgin resources as a raw material in manufacturing has great environmental and economic benefits. However, there is lack of public interest in needs for integrated waste management and its relevant facilities, because of NIMBY syndrome, This article has proposed a system dynamics model for the study of the potential and systemic consequences of resource circulation management system(RCMS) policy for a Sudokwon landfill site in Korea. The results of the study indicate that the effects of RCMS are seen continuously to increase in term with both the community welfare level and the resource and energy level. Moreover the effects of RCMS appear sharply in the first half of the simulation period.

The current industrial development and the Increase of population along Nakdong River have produced a rapid Increase of wastewater discharge. This has resulted in problem of water quality control and management. Although many efforts have been carried out, water quality has not significantly improved. The goal of this study is to design a NGIS-based water quality management system for the scientific water quality control and management in the Nakdong River. For general water quality analysis, QULA2E model was applied to the Nakdong River. A sensitivity analysis was made to determine significant parameters and an optimization was made to estimate optimal values. The calibration and verification were performed by using observed water quality data for Nakdong River. A water qualify management system for Nakdong River was made by connecting the QUAL2E model to ArcView. It allows a Windows-based Graphic User Interface(GUI) to implement all operation with regard to water quality analysis. The modeling system in this study will be an efficient NGIS for planning of water quality management.

Purpose: In this study, we proposed a plan to establish and implement a safety and health management system by utilizing corporate resources so that manufacturing companies can effectively respond to the Serious Accident Punishment Act. Methods: We identified critical factors and response strategies necessary for manufacturing companies to respond to the Severe Accident Punishment Act effectively and surveyed employees working at the company regarding their importance and performance. Results: In this study, we presented a method of strategically constructing the response strategies (20) shown in previous studies by matching them with the company's resources (leadership, organization, budget, education, and awareness). In particular, leadership refers to the ability of managers who can prevent serious accidents by carrying out safety and health security obligations to avoid safety and health hazards or risks to employees in the business or workplace that is controlled, operated, and managed. Conclusion: Based on the manager's firm leadership, the system's purpose and direction must be accurately set and sufficiently communicated to members. In addition, for companies to identify and improve risk factors on their own, a Process approach must be established to improve execution by referring to legal standards together with field managers and supervisors.

본 연구는 국가 하천환경의 관리를 위한 법제도적 체계와 정책 추진과정에서 적용하고 있는 하천환경평가체계에 대해 검토하였으며, 이를 바탕으로 기 제안된 하천환경의 평가분야와 지표의 타당성을 논의함과 동시에 현행 국가정책과의 연계방안을 제시하고자 수행하였다. 국가의 하천환경관리체계는 국토교통부와 환경부로 이원화된 법제도적 체계 속에서 독립적인 위상의 확보가 용이치 않은 가운데 핵심적 사항이라 할 수 있는 국가표준의 하천환경평가체계도 구축되어있지 못한 상태인 것으로 나타났다. 구체적으로 수자원과 수질, 하천환경과 수생태계의 관리측면에서 관련 상위 및 하위의 계획 간 또는 각 계획 내통합적 접근이 매우 미흡할 뿐 만 아니라 하천환경의 현황조사 및 종합분석과 평가에 따른 계획 설계 과정의 일관성과 실효성 역시 확보되어 있지 못한 것으로 나타났다. 국가 하천환경관리체계의 통합적 접근을 위해서는 일차적으로 국가계획간 위계의 정립과 연계성 확보가 매우 중요한 것으로 판단되었으며, 또한 우리나라 하천환경의 제반 특성을 고려하여 개발된 하천환경평가체계는 기존 평가기법과의 정합성 및 연계성을 바탕으로 시급하게 적용되어야 할 것으로 판단되었다. 특히 하천환경자연도와 하천친수도를 평가하는 하천환경평가체계는 하천유역수자원관리계획에 적합한 하천유역 평가법과 하천기본계획에 적합한 하천수계 평가법으로 구분, 제안하였다.

A flood -flow management system model of river basin has been developed in this study. The system model consists of the observation and telemetering system, the rainfall forecasting and data-bank system, the flood runoff simulation system, the dam operation simulation system, the flood forecasting simulation system and the flood warning system. The Multivariate model(MV) and Meterological-factor regression model(FR) for rainfall forecasting and the Streamflow synthesis and reservoir regulation(SSARR) model for flood runoff simulation have been adopted for the development of a new system model for flood-flow management. These models are calibrated to determine the optimal parameters on the basis of observed rainfall, streamflow and other hydrological data during the past flood periods. The flood-flow management system model with SSARR model(FFMM-SR,FFMM-SR(FR) and FFMM-SR(MV)), in which the integrated operation of dams and rainfall forecasting in the basin are considered, is then suggested and applied for flood-flow management and forecasting. The results of the simulations done at the base stations are analysed and were found to be more accurate and effective in the FFMM-SR and FFMM0-SR(MV).
