The main purpose of the research is to suggest a new business model of direct distribution of organic agricultural products cultivated in suburban area. To secure competitiveness, logistics cost reduction is important through direct transaction of organic agricultural products cultivated on suburban area. The research addresses food safety, farmers' income and unemployment issues with Eco-M business model. The research methods include investigation on the followings: current domestic agriculture; related problems on the existing literature reviews; the current status of suburban agriculture; specialty store of eco-friendly agricultural products. Eco-M business model can solve various problems of suburban agriculture supply system, challenges of organic farming specialty stores, unemployment issues, and difficulties of processing verticalization. Future research should include followings. First, there should be comparative analysis between businesses of environment-friendly specialty stores through suburban agriculture and producer's agriculture connected with organic farming market. Second, it is required to develop strategy of environment-friendly specialty stores. Finally, analysis of the potential of Sextic industries is necessary throughout production-process-service process.

Many countries are pursuing the policy of activation of the railway that are means of high-efficiency eco-friendly for a sustainable low-carbon green growth through railroads' logistics, the Korea government also aims to increase railroad logistics two or three times more than present railroad logistics. But there are problems to expand the terminal infrastructure that are the limitation of geographical conditions and huge costs. We are developing the simulation to analyze the result by changing the operation method of yard trailers, reach stackers and gates. This paper aim to analyze gate performance adopting RFID.

GCM(Green Chain Management) is being spread by that companies which apply with eco-friendly concept in entire SCM(Supply Chain Management) perspective is being increased for resolving some recent environmental problems. There are reasons that numerous companies focus on GCM. At first various governments began to directly manage components and material contents about various noxious substances. Second, environment problem management in the entire logistics process from procurement of product materials to distribution of product became to be important according to introduction of certification system that evaluate the environmental impact throughout life-cycle of products. Purposes of this paper are 1) to analyze the GCM process whose important is more increasing in the recent logistics environment change, 2) to comprehend places and sources that generate environmental elements like energy consumption and greenhouse gas emissions in elements of logistics function, and 3) to construct integrated GCM system for observing activity of logistics function throughout life-cycle of products.

본 연구의 목적은 김포양촌 신도시를 대상으로 조성될 생태시설로써 조류생태공원, 에코센터, 생태하천과 생태수로 등에 대한 비용편익을 추정함으로써 그 경제적 타당성을 분석하고자 함이다. 본 연구는 최초로 생태 친화적 신도시개발의 경제성분석을 시도하였다. 생태시설에 대한 모든 시나리오에서 B-C비율은 1을 넘었다. 특히 에코센터의 편익/비용 비율이 5.02-3 75로 가장 높았다. 네 가지 생태시설의 건설비용이 50%증가를 가정한 경우에도 경제적 타당성을 유지하였다. 본 연구는 신도시 건설을 할 경우 생태적 다양성을 갖추는 것이 주거단지조성의 핵심요소임을 시시하고 주택건설의 방향이 탄소배출제로 및 에너지 효율화와 조화된 방향으로 추진될 것을 제안한다.

As environmental concerns continue to grow, green supply chain management (GSCM) is attracting attention as an element of competitive advantage for companies. This study examined internal GSCM practices to show how they influenced the end-point of the supply chain from the perspective of the end-consumer. It identified the effects of environmental concerns on consumer purchasing behavior mediated by the company image of internal GSCM practices. Data were collected through an email survey of Korean consumers. Reliability and validity were verified using SPSS 18.0. Cronbach's alpha, and confirmatory factor analysis. The results showed that environmental concerns had a positive impact on such practices, and the image of internal GSCM practices was found to have a significantly positive effect on consumer purchasing behavior. Companies will have to actively reflect environmental factors in their operational activities, and GSCM implementation will become a necessity. A positive image of internal environmental management and eco-design, which are key elements of internal GSCM practices, strengthened the company's eco-friendly image and ultimately affected consumer purchasing behavior. This suggests that it is important for companies to evaluate their environmental attitude and make eco-friendly products from a consumer's perspective, making it a differentiation strategy for a company in building an eco-friendly corporate image.

지속적인 유가 상승과 탄소배출 규제 강화는 기업들로 하여금 높은 경쟁력을 가지도록 요구한다. 따라서 고객 서비스 증대와 비용절감을 위해 효율적인 물류시스템을 구축하고 운영하는 것에 많은 노력을 기울이고 있으며 비용 경쟁력을 가지는 친환경 산업단지의 필요성이 증대되고 있는 실정이다. 부산시에서는 친환경정책을 통해 경쟁우위를 점하고 부족한 산업단지를 충족시키기 위해 서부산권에 '부산신항배후 국제산업물류도시'를 선정하고 개발을 진행하고 있다. 이러한 산업단지를 구축하기 위해서는 적절한 정책과 화물수송 공동화를 통한 물류시스템이 필요하다. 특히, 산업 단지내 물류시스템의 체계구축을 통한 효율적인 운영은 저비용 친환경적인 측면에서 매우 중요하다. 따라서 본 연구에서는 물류체계를 분석하고 분석내용을 바탕으로 물류네트워크 운영모델을 제시함으로서 산업단지의 기반을 마련하는데 목적이 있다.

Geopolymer concrete (GPC) has emerged as a feasible choice for construction materials as a result of the environmental issues associated with the production of cement. The findings of this study contribute to the development of machine learning methods for estimating the properties of eco-friendly concrete to help reduce CO₂ emissions in the construction industry. The compressive strength (f_c) of GPC is predicted using artificial intelligence approaches in the present study when ground granulated blast-furnace slag (GGBS) is substituted with natural zeolite (NZ), silica fume (SF), and varying NaOH concentrations. For this purpose, two machine learning methods multi-layer perceptron (MLP) and radial basis function (RBF) were considered and hybridized with arithmetic optimization algorithm (AOA), and grey wolf optimization algorithm (GWO). According to the results, all methods performed very well in predicting the f_c of GPC. The proposed AOA - MLP might be identified as the outperformed framework, although other methodologies (AOA - RBF, GWO - RBF, and GWO - MLP) were also reliable in the fc of GPC forecasting process.

IMO has enacted a convention that air pollution due to emissions of ships and sulfur oxides emissions should be significantly reduced by 2020. Based on the current support policies, this work intended to draw up the government support plans required by the shipping companies. Analytic Hierarchy Process analysis was done with factors derived from brainstorming and literature studies. The analysis results showed that the cost factor was generally the most important criterion and the Financial Aid was relatively more important within this cost factor. The policy implications for the regulation of sulfur oxides emissions was provided.

Renewable energy has become more popular with the increase in the use of solar power. Consequently, the disposal of defective and old solar panels is gradually increasing giving rise to a new problem. Furthermore, the efficiency and power output decreases with aging. Researchers worldwide are engaged in solving this problem by developing eco-module technologies that restore and reuse the solar panels according to the defect types rather than simple disposal. The eco-module technology not only solves the environmental problem, but also has economic advantages, such as extending the module life. Replacement of encapsulants contributes to a major portion of the module maintenance plan, as the degradation of encapsulants accounts for 60% of the problems found in modules over the past years. However, the current International Electrotechnical Commission (IEC) standard testing was designed for the commercialization of solar modules. As the problem caused by long-term use is not considered, this method is not suitable for the quality assurance evaluation of the eco-module. Therefore, to design a new accelerated test, this paper provides an overview of EVA degradation and comparison with the IEC and accelerated tests.
