Center for Research of Science and Technology ("PUSPIPTEK") has 460 hectares land area, still maintained as a green area with more than 30% green space. There are 47 centers for research and testing technology, technology-based industries, and as well as public supporting facilities in PUSPIPTEK area. Based on the concepts developed to make this area as an ecological region, PUSPIPTEK can be seen as a model of eco-innovation. The purpose of this research is to develop a model of water, energy and waste management with eco-innovation concept. As a new approach in addressing environmental degradation and maintaining the sustainability of ecosystem, studies related to eco-innovation policy that combines the management of water, energy and waste in the region has not been done. In order to achieve the objectives of the research, a series of techniques for collecting data on PUSPIPTEK existing conditions will be carried out, which includes utilities data (water, electricity, sewage) and master plan of this area. The savings over the implementation of the concept of eco-innovation in water, energy, and waste management were calculated and analyzed using quatitative methods. The amount of cost savings and feasibility were then calculated. Eco innovation in water management among other innovations include the provision of alternative sources of water, overflow of rain water and water environments utilization, and use of gravity to replace the pumping function. Eco-innovation in energy management innovations include the use of LED and solar cell for air conditioning. Eco-innovation in waste management includes methods of composting for organic waste management. The research results: (1) The savings that can be achieved with the implementation of eco innovation in the water management is Rp. 3,032,640 daily, or Rp.1,106,913,600 annually; (2) The savings derived from the implementation of eco innovation through replacement of central AC to AC LiBr Solar Powered will be saved Rp.1,933,992,990 annually and the use of LED lights in the Public street lighting PUSPIPTEK saved Rp.163,454,433 annually; (3) Application of eco innovation in waste management will be able to raise awareness of the environment by sorting organic, inorganic and plastic waste. Composting and plastic waste obtained from the sale revenue of Rp. 44,016,000 per year; (4) Overall, implementation of the eco-innovation system in PUSPIPTEK area can saves Rp. 3,248,377,023 per year, compared to the existing system; and (5)The savings are obtained with implementation of eco-innovation is considered as income.

The purpose of this study is to suggest a actual conditions and expert's role on the green tourism in rural community. There are four types of green tourism in rural villages. It is an alternative tourism that has naturalism and sustainability, not mass tourism. I can find it is a one of the new rural development method in a point of view of rural people's income. Green tourism requires a participation of village peoples. So, management hang on not government office, but village people themselves. By surveying green tourism villages in the case of this study, I propose a few results as follow; firstly, green tourism of Korea will give an innovation to stagnant rural society. Secondly, rural people themselves must participate directly in development and guidance, when every programs are advanced. Thirdly, through this project of green tourism, we expect that urban and rural symbiosisically have a network.

Objectives Despite the great contribution made by chemical substances to the development of modern civilization, their indiscriminate use has caused various kinds of damage to the global environment and human beings. Accordingly, the major developed countries and international society have tried to ensure the safe use of chemicals and a reduction in the use of hazardous chemicals through the establishment of the United Nations Environment Programme and various international agreements. In this reason, we tried to introduce about Green Chemistry progress at the present in worldwide and Korea. Methods We checked and analyzed relative journals, reports using keyword as like Green Chemistry, alternative chemicals, eco-friendly etc. and major country's government homepage search. Results Green Chemistry theory, which argues for the reduction or removal of harmfulness in chemicals throughout their entire life-cycle, has been spreading, and major developed countries, such as the US and Denmark, have developed and operate programs to provide reliable chemical information to help replace hazardous chemicals. Korea has also been conducting studies as like eco-innovation project. Through this project the "Alternative Chemical Search program," has been developed, distributed, and operated since 2011 to provide reliable information to small and medium-sized businesses that have difficulties collecting information to ensure conformity to international regulations. The program provides information that includes the regulations of major countries and Korea, information on 340 alternative chemicals, 70 application cases, and 1:1 consulting. Conclusions The Alternative Chemical Search program is expected to contribute to the establishment of response systems for regulation of Korean small and medium-sized businesses, and it also will be used to provide basic data for Korean hazardous chemical regulation, together with the Act on the Registration and Evaluation, etc. of Chemical Substances and the Chemical Control act, making it possible to establish an infrastructure for Green Chemistry in Korea and to increase national competitiveness.

As the response to climate change becomes a more pressing global issue, so do expectations for climate change in the green information and communication technology (ICT) industry and the possibility of solving environmental problems through ICT. However, because the green ICT industry is still in its early stages, there is little research on it. Understanding the startup ecosystem in the industry is helpful for recognizing innovation trends in emerging technologies such as green ICT. In this regard, this paper investigates the current state and characteristics of the green ICT ecosystem and presents implications based on an examination of startup venture capital investment trends and submarket identification in the green ICT industry as emphasized by the carbon neutrality paradigm shift. The analysis included 4,807 companies and 3,990 funding records, as well as exploratory data analysis and "k-means" clustering techniques.

When an incoming Global Positioning System (GPS) signal is acquired, pull-in search performs a finer search of the Doppler frequency of the incoming signal so that phase lock loop can be quickly stabilized and the receiver can produce an accurate pseudo-range measurement. However, increasing the accuracy of the Doppler frequency estimation often involves a higher computational cost for weaker GPS signals, which delays the position fix. In this paper, we show that the Doppler frequency detectable by a long coherent auto-correlation can be accurately estimated using a complex-weighted sum of consecutive short coherent auto-correlation outputs with a different Doppler frequency hypothesis, and by exploiting this we propose a noise resistant, low-cost and highly accurate Doppler frequency and phase estimation technique based on a reverse directional application of the finite rate of innovation (FRI) technique. We provide a performance and computational complexity analysis to show the feasibility of the proposed technique and compare the performance to conventional techniques using numerous Monte Carlo simulations.

As the climate crisis intensifies, the need to improve the climate resilience of developing countries is ever increasing. Hence, the international community is seeking ways to effectively conduct climate technology transfer by linking the projects with financial mechanisms. However, commercialization of climate technology in developing countries is no easy feat as comprehensive knowledge on the target country is a prerequisite for seeking a suitable technology-financial linkage measure. Hence, in-depth discussions on effective climate technology and financial linkage measures have become an important global agenda, and South Korea, as a country with long experience in climate technology transfer, and a strong ecosystem for public climate technology, should step forward to take up a leading role. Against this backdrop, this paper proposes strategies and implementation measures for linking funds from the Multilateral Development Banks (MDB) with Korea's Public Climate Technology (PCT) by examining several key areas of R&D, international cooperation, and technology commercialization.

Metal additive manufacturing (AM) technologies are classified into two groups according to the consolidation mechanisms and densification degrees of the as-built parts. Densified parts are obtained via a single-step process such as powder bed fusion, directed energy deposition, and sheet lamination AM technologies. Conversely, green bodies are consolidated with the aid of binder phases in multi-step processes such as binder jetting and material extrusion AM. Green-body part shapes are sustained by binder phases, which are removed for the debinding process. Chemical and/or thermal debinding processes are usually devised to enhance debinding kinetics. The pathways to final densification of the green parts are sintering and/or molten metal infiltration. With respect to innovation types, the multi-step metal AM process allows conventional powder metallurgy manufacturing to be innovated continuously. Eliminating cost/time-consuming molds, enlarged 3D design freedom, and wide material selectivity create opportunities for the industrial adoption of multi-step AM technologies. In addition, knowledge of powders and powder metallurgy fuel advances of multi-step AM technologies. In the present study, multi-step AM technologies are briefly introduced from the viewpoint of the entire manufacturing lifecycle.

정부는 지난 2008년 8월 새로운 국가 발전 패러다임으로 ‘저탄소 녹색성장’을 제안한 바 있다. 이 전략의 골자는 저탄소 사회의 구현과 새로운 성장동력을 동시에 확보한다는 것이다. 하지만 전통적으로 많은 학자들은 두 목적이 서로 상충되는 것으로 인식해 왔다. 다시 말해 녹색전략은 환경규제를 강화하게 되고 이것은 기업의 생산비용을 증대시키게 된다는 것이다. 그러나 포터를 비롯한 일단의 학자들은 이것을 근거가 부족하거나 지나치게 정태적인 분석의 결과로 보았다. 또 이들은 적절한 형태의 환경규제는 기술혁신을 유도함으로써 단기적 비용을 상쇄하는 효과를 나타낼 수 있다고 주장하였다. 이들 논쟁에 관해 많은 선행연구가 있지만 실증연구는 대단히 부족한 것이 사실이다. 본 논문은 환경관리를 위한 정부 정책과 기업의 혁신 활동이 어떤 여건에서 기업의 기술혁신을 유도할 수 있는지를 탐색하고자 하였다. 분석 결과, 기업의 녹색경영전략에 따라 경영성과에 차이가 있는 것으로 나타났다. 특히 외부 규제에 대한 대응정도나 내부 녹색경영 의지가 높을수록 기술성, 수익성, 성장성 등이 커지는 경향을 확인할 수 있었다. 그리고 국제 환경규제나 기후변화협약에 대해 기업이 처한 여건 역시 기술과 경영 두 측면에서 경영성과에 영향을 미치는 것으로 나타남으로써 기술혁신활동과 환경규제 그리고 경영성과 간의 상관성을 확인할 수 있었다.

This paper discusses the determinants of green practices and incorporates some empirical findings from a recent study in the petrochemical sector in the Republic of Trinidad and Tobago. The study was comprised of a survey and follow-up interviews with senior executives who participated in the survey. Of fourteen companies involved, the findings affirmed that the investigation of accidents, provision of an emergency response, employee training, decreasing the production of wastes, and pre-treating wastes before disposal should be stressed. Government requirement, the economic reasons and public pressures were the driving forces of green practices. The five most important determinants identified include performance evaluation, financial justification, impacts on company, management leadership and operations integration. Implementing environmental management systems as a feasible approach to green practices in the petrochemical sector was explored. The findings provide guidance that helps organisations to accommodate the determinants of green practices into achieving sustainable environmental goals.

본 논문은 녹색성장 정책의 도입과 집행과정에서 주요 행위자와 이들의 관계를 정책네트워크 이론을 적용하여 분석하였으며, 이를 통해 정책과정에서 나타나는 특징과 전략적 변화를 살펴보았다. 한국에서 녹색성장 정책은 대통령과 직속 기관을 중심으로 도입되고 추진되었으며, 단시간 내에 관련 법 제도 정비가 이루어지고 관련 조직이 설립되는 결과를 낳았다. 이는 주요 행위자로서 대통령과 직속기관을 중심으로 역할이 수행되고 영향력이 집중되었기 때문이다. '녹색성장'이라는 정책문제에 대한 대통령의 관심과 인식변화로 녹색성장은 국정 최우선 과제로 설정되었으며, 정책의 원활한 추진을 위한 자원의 재분배와 전략 수립, 관련 규범과 규칙 등에서의 변화를 수반했다. 결과적으로 새로운 법과 정책, 규제와 정부조직이 나타났으며, 이명박 정부에서 녹색성장은 매우 적극적이고 원활하게 수행되었다. 그러나 민간과 하위 정책행위자의 참여가 부족한 상황에서 상위 정책행위자 중심의 정부 주도로 정책이 추진됨에 따라 정책의 지속성이 약하다는 한계를 나타내기도 하였다. 결국 박근혜 정부가 들어선후, 대통령의 관심과 우선순위가 변경됨에 따라 녹색성장 정책은 주된 추동력을 상실하게 되었다.
