  • Recently, by the whole world paradigm shift to "Low Carbon Green Growth", it is required to renovate National Transportation and Logistics System. Transportation accounts for 21% of the total energy consumption and 20% of the total $CO_2$ emission, and also places its main reliance on fossil fuels. From green point of view, electric railway system is superior to the other transportation alternatives, but also required to develop the innovative technologies for high efficiency and low energy consumption. In this paper, the concept of railway green operation system by regenerative synchronized driving is presented, including the numerical example and the estimated effect.

  • This study aimed at finding directions for Korean agriculture to establish a new paradigm of sustainable development. Various problematic issues and concerns in the environment necessitate the transformation of Korea's development paradigm from unconditional growth to "Green Growth" through new policies on green value and review of various advanced researches. In this research, the environment-friendly agriculture's problems, particularly in agribusiness were analyzed. Drawing from Michael Porter's Value Chain Analysis, this research developed a value chain model in agriculture that reflects the environment and the present situations. Future directions in the agriculture sector were also discussed. Korea realized food self-sufficiency through the green revolution in the early 1970s. However, a lot of problems have also occurred, including ground and water pollution and the destruction of ecosystems as a result of the overuse of pesticides and chemical fertilizers. In the late 1970s, the growing interest on environment-friendly agriculture led to the introduction of sustainable methods and techniques. Unfortunately however, these were not innovative enough to foster environment-friendly agriculture. Thereafter, the consumers' distrust on agricultural products has worsened and concerns about health have increased. In view of this, the Ministry of Food, Agriculture, Forestry and Fisheries introduced in December 1993 a system of Quality-Certified Products for organic and pesticide-free agri-foods. Although a fundamental step toward the sustainability of the global environment, this system was not enough to promote environment-friendly agriculture. In 2008, Korea's vision is for "Low Carbon Green Growth" to move forward while also coping with climate change. But primary sectors in a typical value chain do not consider the green value of their operations nor look at production from an environmental perspective. In order to attain sustainable development, there is a need to use less resources and energy than what is presently used in Korean agricultural and value production. The typical value chain should be transformed into a "closed-loop" such that the beginning and the end of the chain are linked together. Such structure allows the flow of materials, products and even wastes among participants in the chain in a sustained cycle. This may result in a zero-waste sustainable production without destroying the ecosystem.

  • The new paradigm called 'Low Carbon Green Growth' involved in reducing greenhouse gas is on the rise as a critical issue worldwide. The essential of Kyoto protocol issued in 1997 is to achieve the sustainable economic growth environments by converting existing production system to eco-friendly one. The protocol imposes the liability to reduce greenhouse gas to the countries joined to it. The paradigm is directly involved in the energy consumption and environmental pollution caused by construction activities. Value Engineering which are mainly applied in the design phase in practice is a measure to improve the value of a constructed facility by analyzing and/or appraising the functions and costs of it. However, an appropriate method which assesses eco-friendliness of constructed facility has not been propose by researchers. This paper proposes a method which assesses the performance involved in eco-friendliness of constructed facility using Value Engineering (VE) in the design phase. The method estimates the environmental cost relative to the amounts of energy consumption and environmental pollution occurred over the entire project life cycle. The database called "Life Cycle Inventory DB", which stores information about the amounts of environmental pollution, is used. The algorithm which retrieves the amounts of environmental pollutions from the DB and converts them into environmental costs is developed. The algorithm is implemented into a system which quantifies the eco-friendliness of constructed facility in the design phase using VE.

  • 세계 각국은 침체에 빠진 경제를 재건해야 하는 동시에 지구온난화로 촉발된 환경문제까지 고려해야 하는 상황에 놓였다. 이 같은 상황에서 기존의 다양한 선행 연구는 생산증가와 환경보호를 동시에 수용하는 녹색 생산성을 정확하게 분석하지 못한다는 문제를 가지고 있다. 이러한 한계를 극복하기 위해 본 논문에서는 녹색 생산성이라는 새로운 개념을 제시하고 그 도출 방법을 체계화하였다. 뿐만 아니라 녹색생산성에 대한 영향을 미치는 결정적 정책변수를 파악하기 위해 1단계 DEA 분석을 통한 생산성 지수를 비교하고, 이에 기초하여 2단계 붓트렙 회귀분석을 실시하여 그 결정요인을 분석하였다. 1단계 실증분석의 결과, 미국, 일본, 유럽연합에 비해 한국의 녹색 생산성 지표는 크게 미흡한 것으로 나타났으며, 그 원인을 찾기 위한 2단계의 회귀분석 결과, 국가총생산, 에너지집약도, 탄소집약도, 자본집약도, 노동집약도의 변수가 정부의 환경오염 감축 노력보다 중요한 것으로 나타났고, 이를 위해 요소투입형 생산구조에서 요소의 질적 고도화가 필요함을 지적하였다.

  • 세계는 지속가능개발에 대한 관심을 가져왔고, 지속가능의 3가지 가치(환경보전성, 경제성장성, 사회발전성)를 중요시 여겼다. Rio+20 회담은 "녹색경제"에 대해 주목하고 지속가능개발을 위한 방안을 모색하려 했지만, 결론적으로 Rio+20에서 제시한 "The Future We Want"에 대한 답을 찾지 못하여 많은 아쉬움을 가지고 있다. 또한 지속가능개발의 3가지 가치만으로는 지속적인 발전에 한계가 있다고 판단되고, "The Future We Want"에 대한 해답과 지속가능개발의 발전을 위한 방안으로써 5가지 가치 즉, 녹색별(환경보전성, 경제성장성, 사회발전성, 과학기술성, 자율자발성)을 제안한다. 그리고 4대강사업의 결과를 녹색별로 검증함으로써 녹색별 모델을 지속가능발전을 위한 새로운 패러다임으로 제시하고, 대한민국의 안녕강국을 기대한다.

  • Since the industrial revolution, the global environmental problems such as greenhouse gas accumulation and the average temperature increase have caused people's attention. 'Low Carbon, Green Growth' was presented to cope with these global concerns, as one of main policies of 2008 in Korea. The paradigm of a green urban development is started to concern the whole city's energy problems owing to realize 'Low Carbon, Green Growth' in the urban side. The government established a nation's basic energy plan for 20 years, and some local cities made efforts to develop new renewable energy such as the solar, wind and water energy which are suitable to each city's character. As a part of these efforts, the concept of U-Eco city is newly appeared to reflect upon ubiquitous technique, urban ecology and the next generation energy system. However, urban plan is difficult to adopt this next generation energy system with existing laws, regulations and technical systems. The new executive and systematic system is needed to realize the U-Eco city U-Eco for the management of an efficient city. In this study, the authors investigate the concept of the next generation energy system and U-Eco city to realize the energy-efficient city plan and analyze problems to occur during the application of them in an existing city plan. Then, the authors show the remedies to deal with occurred problems.

  • For as to world, the concern about the environment problem is enhanced than any other time in the past because of being 21 century. And the environment problem is highlighted as the world-wide issue. The time of the environment problem intimidates the alive of the mankind and presence of an earth over the time. It becomes the essentiality not being selection in the personal living or the economical viewpoint now to prepare for the climatic modification. As to the company management, the green growth period which it excludes the environment management considering an environment, cannot carry on the company the continued management comes. That is, in the change center of the management paradigm, there is the environment management. Nearly, the greenhouse gas which the publication industry is the environmental toxic material like all industries is generated. The greenhouse gas is ejected in the process of running the manufacturing process and print shop of the various kinds material used as the raw material of the book. Particularly, the tree felling for getting the material of the paper is known to reach the direct influence on the global warming. This study does according to an object it considers and organizes the environment parameter based on this kind of fact as to the publication industry. And it is determined as the reference which is used as the basic materials preparing the case that carbon exhaust right transaction(CAP and TRADE) drawing are enforced in all industries and is sustainable the management of the publication industry and reduces the environmental risk among the company many risk management elements and plans and enforces the publication related policy that there is a value. In the printing publication industry, this study tried to inquire into elements discharging the environmental pollutant or the greenhouse gas. Additionally, in the printed publication production process, it tried to inquire into the effort for an environment-friendly and necessity at the printing paper and the printers ink, regarded as the element discharging the greenhouse gas all kinds of the printing materials, operation of the print shop and all kinds of the machines and recycle process, and etc. These considerations make these industrial field employees aware of the significance about a conservation and environmental protection. They try to give a help in the subsequent study producing quantitatively each environmental parameter emission of green house gas. This makes the calculation of the relative $CO_2$ output reproached ultimately possible. Meanwhile, in a sense, many research protects and improving an environment in connection with the contents of research at the printing publication industrial field is in progress. There will be the voluntary human face that it has to protect an environment but this can not do by the outside factor according to all kinds of environment related law and regulation. Anyway, because of acting on company management as the factor of oppression, the increase of this environment-related correspondence cost could know that the research that the environment loading relates with a procurement and development, environment management system introduction, quality control standard, including, normalizing including a material, and etc. through the part of the effort to reduce the cost low was actively in progress. As to the green growth era, as follows, this paper prescribed the subject and alternative of the print publication industry. It is surrounded by the firstly new digital environment and the generation of the subject. And secondly the printing industry is caused by the point of time when the green growth leaves by the topic which is largest in the global industry and it increases. The printing publication industry has to prepare the bridgehead for the environment-friendly green growth as the alternative for this resolution with first. The support blown in each industry becomes the obligation not being selection. Prestek in which the print publishing was exposed to spend many energies and which is known as the practice of the sustainable print publishing insisted that it mentioned importance of the green printing through the white pages in 2008 and a company had to be the green growth comprised through the environment-friendly activity. The core management for the sustainable printing publication industry presented from Presstack white pages is compacted to 4 words that it is a remove, reduce, recover, and recycle. Second, positively the digital printing(POD) system should be utilized. In the worldwide print out market, the digital printing area stops at the level of 10% or so but the change over and growth of the market of an analog-to-digital will increase rapidly in the future. As to the CEO Jeff Hayes of the Infoland, the offset print referred to that it of the traditional method got old and infirm with the minor phase of the new printing application like the customer to be wanted publication and the print of the digital method led the market. In conclusion, print publishers have to grasp well the market flow in the situation where a digitalization cannot be generalized and a support cannot avoid. And it keeps pace with the flow of the digital age and the recognition about the effort for the development and environment problem have to be raised. Particularly, the active green strategy is employed for the active green strategy.

  • Under the paradigm of 'Eco', the core of sustainability management, this study aims to establish both domestic and international markets and secure competitiveness in the global markets through the development of children's furniture composed of recycled and unharmful materials. Currently, in Europe and in the Western regions, the concepts of 'eco-friendly', 'children', and 'DIY' are well-placed in the daily lives of the people. On the other hand, compared to the domestic demand for eco-friendly children's furniture, the essential approach and the qualitative improvements about the subject are being slowly progressed. Particularly, the process of applying eco-friendly materials and finishing materials to the children's furnitures are mostly in a non-existent state. Thus, in this study, simple application of basic eco-friendly materials such as natural woods or imitation of overseas furniture designs were avoided to create transformable eco-friendly one-touch DIY children's furniture for children's growth and development through the application of eco-friendly processes of technology, design, and other stages of the development process. In other words, under the big category of eco-friendly children's furniture, the furniture was developed through an environmentally-friendly process of universal design that is suitable for children of all ages, and thus, ultimately maximizing the economical effective value and reducing consumption of resources and environmental pollutions.
