  • In this research, the test how the evaluation of the spacial image influenced by the environmental friendly elements included in the visual information, and how the selection of the sound changed depending on the characteristics of spacial image were carried out by the 40 subjects. Vast tracts of green land and the waterfront were highly preferred and impressive than the other spaces. The green music, signal with water sound and bird chirping sound were highly scored. In the frequency characteristics of the factors, the first factor was artificial sound (high at the low frequency band), the second was natural sound(uniform at all frequency band) and the third was water sound (high at the middle and high frequency band over 500 Hz) . This shows that the proposal of the sound which has the frequency characteristics fit to the spacial image should be selected for the soundscape of the target space.

  • 해양환경에 노출된 콘크리트는 육상에서 건설되는 콘크리트와 달리 해풍, 조력, 파도, 파랑 등에 의한 물리적 작용과 해수의 $SO_4{^{2-}}$, $Cl^-$$Mg^{2+}$ 이온 등에 의한 화학적 침식작용 및 동결융해 등 가혹한 환경에 노출되어 콘크리트의 내구성을 크게 저하시킨다. 해중 콘크리트의 대규모 시공은 콘크리트의 강도손실은 물론 알칼리(pH) 및 중금속 등 환경유해물질이 용출될 수 있어 이에 대한 충분한 검토와 연구가 필요한 실정이다. 본 연구에서는 전기로 환원슬래그로부터 CSA 자극제를 개발하고 전기로 산화슬래그를 콘크리트용 골재로 활용하여 인공리프용 친환경콘크리트를 개발하였다. 초기강도는 Normal concrete보다 낮게 나타나 친환경콘크리트의 초기강도 품질향상을 위한 추가적인 연구가 필요하였으며, 친환경콘크리트의 해수저항성은 양생일 1년 대비 평균 강도손실이 8~9% 발생하였다. 고함량 고로슬래그 미분말과 고비중 전기로 산화슬래그 골재를 사용한 친환경콘크리트를 동결융해저항성 재료로써 충분히 활용할 수 있는 가능성을 확인하였다. 친환경콘크리트의 중금속 용출특성은 콘크리트의 수화반응을 통한 경화과정에서 중금속 성분은 화학적 결합을 통해 고정화되기 때문에 환경유해성 기준 이하이거나 검출되지 않아 유해물질 용출에 안전하다는 것을 확인하였다.

  • The food self-support rate on the basis of cereals in Korea is approximately 27%, which will threaten the national food security. The dramatic increase in population accompanied by rapid industrialization in developing countries has caused imbalances in the supply of food and energy. To cope with these global crises over food and energy supplies as well as environmental problems, it is urgently required to develop new environmentally friendly industrial crop varieties to be grown on marginal lands including desertification areas for sustainable development. Sweetpotato (Ipomoea batatas (L.) Lam.) ranks seventh in annual production among food crops in the world. Its wide adaptability on marginal lands and rich nutritional content provide a high potential for preventing malnutrition and enhancing food security in the developing countries. In addition, sweetpotato can be developed as a bioreactor to produce valuable industrial materials including bio-ethanol, functional feed and antioxidants by molecular breeding. In this respect, we focus on the molecular breeding of sweetpotato with multi-function on marginal lands. The strategies for development of environmentally friendly industrial sweetpotato will be introduced and discussed.

  • The world has faced with various environmental problems such as climatic change, global pollution, and depletion of natural resources. Conventional economic development continues not only to intensify the magnitude of the problems but also to damage growth potential of future generations. Therefore, recent manufacturers are highly required to accommodate themselves to sustainable development that aims at preventing the loss to the future generations. Moreover, the manufacturers are under heavy pressure from various environmental regulations. This paper proposes green bill of material (Green-BOM) which conforms to the environmental regulations to restructure eco-friendly manufacturing system. Green-BOM is useful for managing green product and process information to satisfy several environmental regulations by recording energy consumption, recycle rate, volatile organic compounds (VOCs), substance information, and so on.

  • In spite of numerous advantages in railroads such as mass transportation, high reliability, and environmental soundness etc., the value of railroad construction is relatively underestimated compared to road. This is because the current method of evaluation focuses mainly on economic effect. In this study, considering recent research results, the environmental value of railroad construction was assessed by calculating the effect of reduction of emissions and water contamination. With these two benefits, the environmental effect produced by railroads and road construction was calculated and compared to each other using EMME/3. As a result, the senario 4 which considers 'Hot/Cold start' condition and water contamination had highest benefits. Furthermore, the environmental effect produced by railroad is 55~101% higher than road construction. If the suggested method is used in the current appraisal system, the environment-friendly mode like railway would be highly valued, much more than before.
