최근 기후변화로 발생되는 폭우, 강풍 등의 기상현상으로 인해 하천범람, 내수침수, 해수범람 등 특히 해안도시지역에서의 물 문제는 날로 심화되고 있다. 이에 정부에서는 저영향개발(Low Impact Development, LID) 사업 및 친환경그린인프라(Green Infrastructure, GI) 기술요소의 적용확대를 추진하고 있다. 이에 환경부에서는 환경기술개발사업의 일환으로 '그린인프라 제도/정책 및 재원관리의 선진화(2021)' 연구용역을 통해 관련 추진체계 구축, 제도 개선방안 등을 모색하였다. 해당 연구에서는 기존의 LID 및 GI 관련 정책·제도 개선, 강우유출수 관리목표 설정방안, 투수/불투수도 제작 지침 마련, 시민인식조사 등을 통해 그린인프라 확대를 위한 과학적 근거 및 통합관리제도를 마련하였다. 이와 더불어 2013년부터 도시지역의 우수유출 저감, 물순환 구조 개선, 비점오염원 관리를 위해 '그린빗물인프라(Green Stormwater Infrastructure, GSI) 조성 사업'을 추진하여 국비지원을 지속하고 있다. 'GSI 조성사업'은 2014년 공공청사 중심에서 학교, 도서관, 체육시설, 공원 등 적용 범위를 확대 하고 있는 추세이나, 수도권지역과 물순환선도도시 조성사업이 진행중인 5개 지역(김해시, 광주시, 안동시, 울산시, 대전시)을 제외한 각 지자체에서는 실효성 있는 추진체계 및 가이드라인 부존 등의 문제로 적용에 어려움을 겪고 있다. 이에 경상남도는 지역적 특성을 반영한 GSI 조성 추진체계 마련을 목표로 본 연구용역을 추진하였으며, GSI 관련 국내외 현황조사, GSI 조성을 위한 공공청사의 우선순위 선정, 지형적(토지피복, 토양형 등), 기상학적 현황을 토대로 한 우선순위 선정, 이를 통합한 경남형 GSI 조성 추진체계를 제시하고자 한다.

Climate change has recently become a serious global issue, and carbon emissions and energy consumption are increasing, particularly in cities where economic activities and populations are concentrated. Accordingly, various countries worldwide are promoting the Green New Deal and promoting urban-centered climate change response policies with the aim of carbon neutrality. In Korea, following the "smart green city" project that creates a city where humans and the environment coexist, a similar "carbon neutral green city" policy is set to be introduced. Therefore, in this study, implications and directions for the sustainable introduction of the carbon neutral green city policy will be derived by comparing and analyzing the State and Tribal Assistance Grants of the U.S. bipartisan infrastructure law and the smart green city of the Korean new deal.

Recently, urbanization has become a serious issue, as there is imbalance between regions and various environmental problems occur intensively in cities. Therefore, cities all over the world are promoting the Green New Deal and trying to realize carbon neutrality. Accordingly, the European Union is leading the creation of carbon-neutral cities by promoting policies aimed at rapidly realizing carbon neutrality. In Korea, projects such as U-City and Smart City have also been promoted continuously for many years, and recently, the projects Smart Green City and Carbon Neutral Green City have been introduced. Therefore, this study aimed to derive directions and implications for future projects based on policies to address climate change by analyzing the guidelines for the Smart Green City project and the project plans of Gimhae-si and Gangjin-gun, which are the leading projects in the Smart Green City business model and are equipped with an extensive budget.

최근 환경부에서 발표한 「제3차(2021~2025) 강우유출 비점오염관리 종합대책(2020)」에 의하면, 우리나라는 지난 50년간 급격한 도시화, 산업화 과정을 거치면서 불투수면적이 전 국토의 약 22.4%에 달한다고 보고되고 있다. 특히 전체 소권역의 6%에 해당하는 51개 소권역의 경우 불투수 면적률 25%를 넘어서고 있는 것으로 조사되었다. 이러한 불투수면의 증가는 기후변화에 의한 영향으로 토양 침투량과 기저유출량을 감소, 갈수기 하천건천화 심화, 우기 표면유출수 증가를 가중시키며 이로인한 비점오염물질 유입 증가, 수질 악화의 원인으로 작용 될 수 있다. 이에 정부에서는 저영향개발(Low Impact Development, LID) 사업 및 친환경그린인프라(Green Infrastructure, GI) 기술요소를 적용하여 도시지역 기후위기 대응 수단의 일원으로 우수유출 저감, 물순환 구조 개선, 비점오염원을 관리하고자 '그린빗물인프라(Green Stormwater Infrastructure, GSI) 조성 사업'을 추진하여 공공청사를 중심으로 학교, 도서관, 체육시설, 공원 등 적용 범위를 확대하고 있다. 이에 본 연구에서는 기후변화에 가장 취약한 해안도시지역인 경상남도에 위치하고 있으며, 불투수면적이 높고 노후화된 소규모 청사 2곳을 시범 구역으로 선정하였다. 각 시범 구역별 GSI 시설 적용이 가능한 주차장, 화단, 옥상 등의 개선방안을 제시하였으며, 적용 규모를 달리하여 물순환·물 환경 개선 효과를 검증하였다. 검증에는 국내에서 개발된 K-LIDM 모형을 활용한 우수유출저감 및 직접유출체적 산정결과를 통해 물순환 효과를, 국립환경과학원에서 제시되고 있는 '토지계 지목별 발생부하원단위', 수질환경개선 보고서에서 제시된 침투형, 식생형 비점오염저감시설의 저감효율을 활용하여 물순환 저감효과를 분석하여 비교하였다.

This study has developed a design indicator required to promote green remodeling in school facilities. And, implemented the green remodeling pilot test on the school facilities that are planning actual remodeling. This pilot test suggested user participation design methodology such as verification of the developed design indicator, design goal setting, evaluation and adjustment of design proposal. The Green Remodeling Design Indicators were classified into 3 large categories of architectural performance, usability, and design through analysis of cases related to 'green buildings' and 'remodeling'. We have developed nine middle categories such as architectural and structural performance, facility performance, environmentally-friendly, circulation, space, amenity, harmony with surroundings, form and symbolization. In addition, 42 detailed indicators were developed for each category, including general, functional, and special indicators. For the verification of this study, two green remodeling design workshops were conducted for Gwangju J elementary school. The first design workshop presented the importance of the design indicator and set the goal of the design plan of green remodeling for project. And, the second Workshop presented the evaluation of the satisfaction with the design and the direction of future adjustment for project. The design indicator developed in this study can be utilized as a design indicator of design quality management and decision system for the school green remodeling in the future. In addition, by accumulating information on the Green Remodeling Project, it is necessary to spread green remodeling and construct a sustainable building environment.

This study is suggested to enlarge the green area and to connect and improve the present green areas by deriving the lines of community greenway using living areas and community spaces close to the life of residence in Nam-gu. The purpose of this paper is to suggest the method of establishing greenway for the formation of community in which the residence can grow the community spirit and love their living space much more. Land-use status, green coverage ratio, and impermeability paving ratio are investigated. The community facilities are classified. The highest is educational facility, which is 7.7%, the green facility is 1.9% and the total area of community facilities which is 21.4%. The total area of Nam-gu is divided into 31 zones in total according to the administrative districts, the mail roads and reserved land of railroad and urban development. The total 20 lines of community greenway lines are chosen and the total length of lines is 18.2km. Finally, the characteristics of community greenway lines are analysed, the characteristics of community greenway lines are overall estimated according to the land-use, the street environment and the community facility. The classification system of community greenway is established on the basis on the function and purpose of greenway, the present status of land-use and the type of community facility. Based on the field investigation, the 6 greenway types are suggested considering the interconnection. The method of establishment of community greenway is suggested according to the principle of function and purpose, the principle of land-use and the principle of use of the facilities. Furthermore, the planting methods suitable to each greenway type are suggested in the building planting case of wall planting, roof planting, veranda planting, etc., and in the complex planting of parks, schools, roads, parking lots and other small areas.

La_0.7Sr_0.3MnO₃ precursor solution were prepared by a sol-gel method. La_0.7Sr_0.3MnO₃ thin films were fabricated by a spin-coating method on a Pt/Ti/SiO₂/Si substrate. Structural and electrical properties with the variation of sintering temperature were measured. All specimens exhibited a polycrystalline orthorhombic crystal structure, and the average thickness of the specimens coated 6 times decreased from about 427 nm to 383 nm as the sintering temperature increased from 740℃ to 830℃. Electrical resistance decreased as the sintering temperature increased. In the La_0.7Sr_0.3MnO₃ thin films sintered at 830℃, electrical resistivity, TCR, B-value, and activation energy were 0.0374 mΩ·cm, 0.316%/℃, 296 K and 0.023 eV, respectively.
