해외 주요 국가와 비교 고찰을 통한 인체조직기증 활성화 방안

현윤정(Yun-Jung Hyun),이난영(Nan Young Lee),김동자(Dong Ja Kim) 한국산학기술학회 2020 한국산학기술학회논문지 Vol.21 No.12

현대 사회는 장기 및 인체조직기증에 대한 요구도가 높아지고 있으나, 우리나라에서 인체조직기증에 대하여 인식도와 기증률이 낮아 기증 활성화를 위한 현실적인 방안에 대한 연구가 필요할 것으로 사료된다. 본 연구는 국내외 관련 문헌고찰 및 나라별 이식 등록기구 홈페이지 자료를 참조하여, 인체조직기증과 관련한 국내 법률과 운영 제도 현황을 분석하였으며, 해외 주요 국가와 비교 고찰하였다. 본 연구를 통하여 국내 인체조직기증 활성화 방안으로 법률적 측면에서 이원화된 장기와 조직이식에 관한 법체계의 통합화, 제도 운영적 측면에서 과도한 압력이 없는 국가의 장기기증에 대한 추정적 동의 방식인 Opt-out 제도의 활성화와 사회 문화적 측면에서 대국민 홍보 활성화를 제시하였다. 그러나 추정적 동의 방식은 다양한 사회적 공론화 단계가 필요하며, 거부 의사를 위한 등록체계 운영사항에 대해 국내 실정에 맞는 이해가 있어야 할 것이다. 결론적으로 외국에 비하여 낮은 장기 및 인체조직기증을 활성화하기 위한 법적 제도정비가 요구되며, 기증에 대한 긍정적 인식 전환, 대중 홍보 및 사후 기증자와 가족에 대한 지원 등이 필요할 것으로 사료된다. In modern society, there is a growing demand for human tissue donation along with organ donation. However, the awareness of tissue donation and actual donation rates remain very low in South Korea. This study was undertaken to evaluate the current status of domestic laws and systems, and to compare them with the operation systems of major foreign countries, by reviewing literature and web sites of organ donation and registration. The authors present three measures to promote human tissue donation in Korea: integration of a dual legal system in a legal aspect, vitalization of the Opt-out system in terms of system operation, and activation of public relations in terms of social and cultural aspects. The Opt-out system, in particular, is the most effective way to activate transplants in the form of presumed consent of countries without undue pressure. However, the presumed consent method requires various stages of social public debate, and the requirement is a proper domestic understanding of the registration system for rejection. In conclusion, we believe the solution towards a positive inclination for organ donation is a public policy to increase the supply for organs and human tissue transplants, and positive perception of donations, public promotion, and support for postmortem donors and their families.

In this study, we suggested the management scheme of analyzing the national and oversea related policy against soil and groundwater contamination by radioactive materials due to nuclear accidents. In Korea, we need to remedy swiftly the contaminated land due to intensive land development demand. So, we need to develop more effective management scheme to recover actively the land contaminated by radioactive materials. We require to improve monitoring network, to expand media-specific monitoring system, to prepare management system for remediation of contaminated land, and to develop flow work for soil and groundwater remediation.

Well production by a riverbank filtration facility with multi-radial collector well systems in Jeungsan-ri, Changnyeong gun, Korea was evaluated. In this study, the drawdown at collector wells due to pumping and groundwater inflow rates along the horizontal arms of the collector wells were computed through numerical simulations. Sensitivities of the well production to hydraulic conductivity and well flow coefficient, which represents the resistance to the flow from the aquifer to the horizontal arms, were analyzed. Simulation results showed that, with given proposed pumping rate conditions, the drawdown in the caisson exceeded maximum drawdown constraints in the study site and the adjustment of the pumping rate at each well is needed. The drawdown is affected by the hydraulic conductivity of the main aquifer and the well flow coefficient, which means the profound field investigation of the study site is needed to accurately estimate the efficiency of riverbank filtration through radial collector wells.

Brownfields, properties abandoned or underused due to former contaminations and/or associated environmental stigma, has long been one of pervasive environmental problems and a critical sustainable development concern in developed countries. We are yet to face the brownfields issues, most likely due to the nation`s relatively short history of hazardous waste site regulation and its liability burdens imposed. We advocate a proactive policy initiative by the central government for revitalization of brownfields located in economically distressed areas, which shares many of the characteristics that led to the problems associatedwith the stigma of brownfields in the U.S, including,most notably, unknown or insolvent responsible parties, and reluctance of third-party acquisition and reuse due to difficulties in recovering cost of site remediation. For the new policy direction, we suggest a community-driven local brownfields restoration and reuse program in which local governments and residents of impacted communitieswork in partnershipwith the central government and private developers towards local empowerment. The term “local brownfields” indicates soil and groundwater contaminated properties that are located in disenfranchised areas while sharing the common characteristics of brownfields. Investigated nationwide distribution of the potential local brownfields, and the reviews of theU.S. and Japanese brownfields redevelopment cases studies, we identified the key factors for successful brownfields redevelopment, including a local development vision, leadership and a strong public-private partnership. We added a critical overview of the brownfields redevelopment experiences within the nation. For the analysis of the cases, we developed a set of assessment indicators evaluating the three substantiality pillars of environment, economy, and society, and the results of surveys on the local government officials and experts regarding the demands, administrative priorities, and prospects of the local brownfields revitalization. As a result, we suggest a targeted strategy framework for the local brownfields revitalization: the revitalization should accomplish three sequential goals of (1) recovering environmental potential of the contaminated sites, (2) community-driven redevelopment, and (3) local empowering and life quality enhancement. To achieve these goals, a targeted strategy framework is needed, for the four categories of the local brownfields, classified based on the environmental and economic potentials:(1) central government-driven (high environmental potential, low economic potential); (2) private development (low environmental potential, high economic potential); (3) priority-based (low environmental potential, low economic potential); and (4) local government-driven (high environmental potential, high economic potential)

본 연구는 기존의 지하수 오염 취약성 평가 방법을 개선하고, 연구지역에 적용하여 보다 정량적인 지하수 오염 취약성 분석을 기반으로 지하수 관리 우선 대상 지역을 선정하는 것이다. 이를 위하여 첫째, 기존의‘잠재오염’중심의 지하수 오염 취약성 평가 방법을 오염을 완화시키는‘대응능력’을 고려한 방법론으로 개선하였다. 둘째, 계층분석 방법(AHP)과 지하수 전문가의 설문을 바탕으로 지하수 오염 취약성 평가 인자의 가중치를 산정하였다. 셋째, 광역지자체(경기도)를 연구지역으로 선정하고 개선된 방법론 및 가중치를 GIS로 구현하여 실제 지하수 오염 취약성 평가를 수행하였다. 넷째, 정량적 지하수 오염 취약성 평가도를 바탕으로 지하수 오염 관리 우선 대상 지역을 선정하였다. 본 연구에서 개선된 지하수 오염 취약성 평가 세부 평가인자는 총 15개 이며, 이에 대한 AHP를 활용한 가중치의 산정결과에서 기존의‘잠재오염’에 해당하는 평가인자 보다 신규로 개선된‘대응능력’이 높은 가중치로 분석되었다. 또한 GIS를 활용한 경기도 지역의 지하수 오염 취약성 평가 결과 서울에 인접한 고양시 및 광명시 등이 지하수 오염 취약성이 높았으며, 포천시 및 양평군이 상대적으로 취약성이 낮은 것으로 분석되었다. 본 연구에서는 기존의 지하수 오염 취약성 평가를 개선하였고 실제 연구지역에 적용하였다. 본 연구의 결과는 향후 국가 및 지자체 차원의 지하수 관리 기본계획에 직간접적으로 활용이 가능할 것으로 판단된다. The purpose of this study is to improve the previous groundwater contamination vulnerability assessment method, apply it to the study area, and select priority areas for groundwater management based on the quantitative analysis of groundwater contamination vulnerability. For this purpose, first, the previous‘potential contamination’ based on groundwater contamination vulnerability assessment method was upgraded to the methodology considering‘adaptation capacity’which reduced contamination. Second, the weight of groundwater contamination vulnerability assessment factors was calculated based on the analytical hierarchy process(AHP) and the result of survey targeting groundwater experts. Third, Gyeonggi-do was selected as the study area and the improved methodology and weight were implemented with GIS and actual groundwater contamination vulnerability assessment was carried out. Fourth, the priority area for groundwater contamination management was selected based on the quantitative groundwater contamination vulnerability assessment diagram. The improved detailed groundwater contamination vulnerability assessment factors in this study were a total of 15 factors, and 15 factors were analyzed as new and improved weight with higher``adaptation capacity`` than the assessment factor corresponding to the previous ``potential contamination`` in the weight calculation result using AHP. Also, the result of groundwater contamination vulnerability assessment in Gyeonggi Province using GIS showed that Goyang and Gwangmyeong which were adjacent to Seoul had a high groundwater contamination vulnerability and Pocheon and Yangpyeong County had a relatively low groundwater contamination vulnerability. In this study, the previous groundwater contamination vulnerability assessment was improved and applied to study areas actually. The result of this study can be utilized both directly and indirectly for the groundwater management master plan at national and local government level in the future.
