  • Hydrogen is considered a key energy source to achieve carbon neutrality through the global goal of 'net zero'. Due to limitations in producing green hydrogen domestically, Korean companies are interested in importing green hydrogen produced overseas. The Middle East has high-quality solar energy resources and is attracting attention as a region producing green hydrogen using renewable energy. To build a green ammonia plant, optimization of the production facility configuration and economic feasibility analysis are required. It is expected that it will contribute to reviewing the economic feasibility of constructing overseas hydrogen production plants through preliminary economic feasibility analysis.

  • 최근 녹색기후기금 (GCF, Green Climate Fund) 사무국의 한국유치를 계기로 기존에 한국이 주도해 설립한 글로벌녹색성장센터 (GGGI)와 녹색기술센터 (GTC)와 더불어 한국은 글로벌 녹색성장을 선도하는 전 세계 녹색성장의 허브로 자리매김하게 되었다. 그러나 이와 같은 선진경제로의 도약을 위해서는 무엇보다 한국경제가 모범적인 녹색성장의 정책 추진이 필수적이라 할 것이다. 이는 최근 이산화탄소배출량의 성장률에 있어 중국에 이어 세계 2위의 불명예스런 한국의 입장에서 더욱 절실히 요구되는 상황이라 하겠다. 특히 이와 같은 녹색성장의 지속적인 경쟁력 우위를 주도하기 위해서는 무엇보다 낙후된 한국의 물류산업에 대한 전면적인 개편이 필요하다고 할 것이다. 이는 운송산업이 전세계 이산화탄소배출량의 21%정도를 차지하는 가장 전략적으로 중요하면서도 취약한 분야이기 때문이다. 이에 따라 물류 및 운송산업에 대해 녹색 생산성을 실증분석하고 이에 기초한 전략적 대안을 제시하는 것은 한국의 통상정책의 가장 중요하고도 의미가 있는 연구라 할 것이다. 이를 위해 본 연구는 기존의 전통적 생산성개념에 환경오염변수를 고려한 방향적 거리함수(directional distance function)와 Malmquist 지수 (ML지수) 가운데에서도 가장 최근에 새롭게 제시된 총체적 ML지수 (Global Malmquist-Luenberger Index, GML) 연구 모형을 기초로 환경 보호와 경제개발을 조화롭게 추진하기 위한 녹색생산성의 실질적인 정책 방향의 패러다임을 제시하고 있다.

  • There is rising interest in green energy, energy efficient equipment, and products as countries show increased interest in 'Low Carbon and Green Growth'. The cellphone has become one of the essential influences on modem people beyond the meaning itself by the release and the commercialization of the Smartphone. Thus, it considers that the introduction of fashion for cellphones and digital devices to be always on should be a quite natural design attempt for humans to wear clothes at all times. In addition, outdoor activities increase as the population enjoys more sports and leisure time that requires the development of specialized outwear such as the development of a functional jacket. This specialized field is associated with higher value-added businesses. This study made a prototype of a functional jacket equipped with solar cells that established a system of a fashion design that is harmonious with green growth as a plan to measure of fashion design for green growth. The objects of this study are as follow: First, the study seeks a design method for green growth. Second, it makes a prototype to present the improved design method. Third, it presents the establishment of a design system that considers green growth and the concrete measures practical for the system. It established the design system and made the prototype of functional jacket equipped with solar cells, LED, and digital devices as a measure of design for green growth based on the improvement plan of the design that the problems had been supplemented for. Previous studies were mainly about prototypes that attempted to equip mobile digital devices as a study of smart wear; however, this study leaves the issue of power supply for a follow-up study that is different from preceding studies.

  • 21세기는 유기체적 세계관의 발달과 함께 환경친화적 접근이 조형계에서 크게 부각되고 있다. 이제 환경친화디자인은 단순히 환경보호적인 차원을 넘어 인간과 기술, 환경이 함께 호흡하는 유기체적인 환경친화, 환경과의 일치의 개념으로 발전해 가고 있다. 그러므로 본고는 현대에 발전하고 있는 환경친화디자인의 유형, 즉 자연보호적인 접근이 중심이 된 입장과 인간과 환경의 친화관계 회복이 중심이 된 입장의 두 가지 환경친화디자인 유형을 조사하고 이의 필요성과 Green Amenity에 의거한 기능을 분석하고자 한다. 그리고 이 중에서 단절된 인간과 자연환경의 유기적 연결성을 강조하는 환경친화디자인에 초점을 맞추어 이에 해당하는 공간 디자인 사례를 제시하고자 한다. 이를 통해 인간이 소원하는 삶과 환경에는 편리함과 관련된 기술적 물리환경 뿐만이 아니라 생물적 소산을 이용한 자연친화적 구상이 필요함을 논증해 보고자 한다. 공간디자인에 있어서 이런 접근은 인간과 자연의 단절된 친화관계 회복에 도움을 줄 수 있으며 이렇게 인간과 자연의 친밀감이 회복될 때에 자연보호를 위한 인간의 노력도 유기체적 방향성을 가지고 바람직한 성과를 거둘 수 있다고 본다.

  • This study aims to analyze the qualitative and quantitative effects of environmental policies in terms of green space management using logistic regression model(LRM). Landsat satellite imageries in 1985, 1992, 2000, 2008, and 2015 are classified using a hybrid-classification method. Based on these classified maps, logistic regression model having a deforestation tendency of the past is built. Binary green space change map is used for the dependent variable and four explanatory variables are used: distance from green space, distance from settlements, elevation, and slope. The green space map of 2008 and 2015 is predicted using the constructed model. The conservation effect of Ulsan's environmental policies is quantified through the numerical comparison of green area between the predicted and real data. Time-series analysis of green space showed that restoration and destruction of green space are highly related to human activities rather than natural land transition. The effect of green space management policy was spatially-explicit and brought a significant increase in green space. Furthermore, as a result of quantitative analysis, Ulsan's environmental policy had effects of conserving and restoring 111.75㎢ and 175.45㎢ respectively for the periods of eight and fifteen years. Among four variables, slope was the most determinant factor that accounts for the destruction of green space in the city. This study presents logistic regression model as a way of evaluating the effect of environmental policies that have been practiced in the city. It has its significance in that it allows us a comprehensive understanding of the effect by considering every direct and indirect effect from other domains, such as air and water, on green space. We conclude discussing practicability of implementing environmental policy in terms of green space management with the focus on a non-statutory plan.

  • In the field of soil and groundwater remediation, sustainability was merged into remediation process and green remediation was initiated within the concept of sustainable development. Green remediation was defined and has been already applied to the remediation fields in U.S. In the case of Europe, green remediation has been evaluated for the application of green technology in the remediation industry and they especially defined sustainable remediation following idea of sustainable development. Although green and sustainable remediation is global trends, there are only a few cases about application of green remediation in South Korea. It is needed to develop soil and groundwater remediation technology towards green remediation, considering "Green Growth" as policy direction in South Korea.

  • The purpose of the study is to analyze the existing situation of the green buffer zone in the large scale industrial site and other major residential apartment areas. In this study, it is specifically intended that the planning guideline be upgraded to adopt future landuse trends and thus to suggest design criteria for management of the buffer zone. The framework of the analysis is to review the current landuse, noise reduction, ecological implications and landscape in general. Although the major function of a green buffer zone is considered to protect the residential area from various hazards of industrial, traffic, and visual environment, the situation is that most of the zones are maintained at a minimum level of services by local government. The study carried out intensively almost every type of case studied throughout the country, which implies that the management of the green buffer zone should be expanded physically enough to function for its original objectives. The study recommends that ecological management of the green buffer zone be emphasized and therefore the criteria for this purpose as well as noise issue should be developed prior to the landuse aspects. The study suggests specific guidelines for planning and design for the green buffer zone development. This study should be verified positively through the sustainable monitoring and requires nationwide and overall examination so that it may be applied to whole green spaces.
