Considerable amount of resources on roads, basic infrastructure, to promote economic development and distribution of goods is invested. Despite the necessity, its undesirable side effects are various environmental problems In order to efficiently evaluate these problems more than before, planning indictors for environment-friendly road constructions is proposed in this study. First, we make an investigation into real-life cases where the extracted planning indicators were applied. Second, it is suggested that an alternative assessment method efficaciously evaluate and/or adopt extracted planning indictors on road construction projects. Finally, criteria to determine environmental impacts with respect to planning indicators and apply them into real cases is proposed. This study has its significance in upgrading past pro-environmental indictors for road construction, suggesting reasonable applications of planning indicators, and setting criteria to determine environmental impacts based on planning indicators.

Removal work about weeds that grow naturally on road and industrial complex is attaining ordinary times but is suffering difficulty in weeding work by strong self-generation power. In the meantime, going side by side with these manual processing and weeding work through construction of weed-proof seat is attaining, but economic performance, limitation of application region and withdrawal processing problem are being blamed for shortcoming. The scope of this study is about the manufacture of weed-proof mortar using eco-friendly industrial byproducts characterized by an economic and simplicity for not limited to loss of function as a product recovered after treatment. After the carried out the various experiments and actual construction for the selection of mixing materials and derivation of appropriate mix, through the comparison and analysis of results, it was investigated the research results of weed-proof mortar for fundamental development.

Recently we are limiting use of toxic material of lead, mercury, cadmium, hexavalent chromium, PBB, etc. by a nation environment regulation guidance in Europe, the United States, China and Japan. In this paper, we developed manufacture method and RHD tag of environment material using Hanji, Broussonetia Kazinoki Siebold, and PLOYCABONATE, etc. The developed RFID tag stick to each layer interval using environment material which is minimized environment pollutant.

전기자동차는 석유 연료와 엔진을 사용하지 않고, 전기 배터리와 전기모터를 사용하는 자동차이다. 그동안 전기자동차는 가솔린 자동차보다 오랜 역사를 갖고 있었으나 배터리 중량, 충전 시간 등의 문제로 인해 실용화되지 못했다. 그러나 최근 들어 경제성과 친환경성을 만족시키면서 GM, 르노 등을 중심으로 전기자동차가 시판되고 있고, 국내에서도 활발히 개발되고 있다. 본고에서는 미국, 일본, 유럽, 중국과 국내의 전기자동차 관련 정책을 살펴보고 정책적 시사점을 도출하고자 한다.

최근 차량하중의 대형화에 의해 교량구조물은 사용년수가 증가함에 따라 노후손상에 의해 당초의 설계능력을 발휘하지 못하는 경우가 종종 있으며, 이에 대해 교량구조물의 내하력을 증강시키기 위하여 여러 가지 보수 보강 공법들이 사용되고 있다. 특히 재료의 내부식성, 친환경성 등을 고려하여 GFRP(Glass Fiber Reinforced Plastic)에 의한 보강이 점차 증가하는 추세에 있으나, 아직까지 기존 철근콘크리트 부재와 보강되는 GFRP 부재의 합성에 의한 해석기술에 대한 연구가 많지 않은 실정이다.(중략)

The existing transportation system, which is based on internal combustion engines, is rapidly being converted to electrification. Thus, eco-friendly public transportation with high transportation efficiency will continue to spread throughout the market in the near future. The purpose of this study is to compare and analyze the cognitive characteristics of passengers redgarding the technical and social factors of various public transportation means to help a successful introduction of eco-friendly public transit. Through a survey questionnaire (N=485), seven factors of seven transportation modes were evaluated and analyzed using principal component analysis. As a result, it is confirmed that potential passengers have high expectations for the eco-friendliness and city image of the eco-friendly buses. Also, it is confirmed that eco-friendly buses are superior in cleanliness and ride comfort than diesel buses. Given the study's results, this study identifies the cognitive characteristics of passengers regarding eco-friendly public transportation. We hope that these results will be used as basic information for image positioning and improved service with the use of eco-friendly transportation.

According to the latest report by the Customer Protection Board, those who moved into newly constructed buildings are complaining about unidentified pains, asking for more careful selection of constructive materials for prevention of such potential problems. It is internationally recognized today that ecological materials can serve a significant factor for users' health, environmental protection and better industrial competitiveness. This study examined eco-design aspects of each interior material through web site search, in order to help customers learn about and capitalize on eco materials in a proper manner. As a result, 1. It turned out that the domestic industry are giving an impetus to releasing new eco items focusing on lower VOCs emission or addition of functional components as part of the marketing strategy. However, it is recommended that company understand significance of life cycle, and produce eco-concept materials. 2. The reliable standard for choosing the domestic material is EL, HB, GR marks. It is desirable to enhance recycling technologies and expand the sustainable consumption. customer class, since many recycled items are not developed. 3. The sourcing is a vulnerable part in terms of the concept of being environment-friendly material. Therefore, many manufacturers should design the easy knock-down products and produce the good items using recycled materials instead of new raw materials. Also solutions for making the energy from burning material should be studied. 4. The guidebook or manual with correct information about eco-materials is required to promote production and consumption with sustainable concept. 5. Many manufacturers are emphasizing ecological materials for customers, but some of them intended to disrupt customers' proper selection by promoting even unverified items to be environment-friendly.
