최근 들어 외국에서는 오염된 토양을 평가하고 복원하기 위한 법적인 규제로써 전함량 대신에 오염물질의 노출과 생물유효도를 평가하는 도구를 개발하려는 움직임이 있다. 토양오염 물질의 위해도를 관리하기 위해서는 전함량 보다는 생물학적 이용 가능한 함량을 파악하는 것이 중요하다. 수많은 연구자들이 생물유효도를 평가하기 위한 다양한 연구들을 진행하여 왔으나, 아직 생물유효도를 평가하기 위한 표준 분석법이 개발되어 있지 않은 실정이다. 이 논문에서는 생물유효도 관점에서 토양에서의 중금속의 거동 특성을 이해하고, 오염된 농경지 토양관리에 적용해 보고자 하였다.

This study was carried out for improving the effectiveness of water resources development project through local resident opinions in the environmental impact assessment(EIA). The EIA reports of seven dams were examined. Four dams -Youngju Dam, Seongduck Dam, Buhang Dam and Hantangang Dam- which included many local opinions including 470 opinions of 341 local residents were selected to be analyzed. Local residents submitted their opinions in the six fields which are meteorological phenomena, water quality, land use, fauna and flora, noise and vibration, and residence, and the major opinions of those opinions came from the atmosphere environment field which is 32% of total opinions and social and economic field which is 38% of total opinions, respectively. In submerged area, opinions of the measure for migration and compensation were 91% and in non-submerged area, opinions of the measure for meteorological phenomena was 86%. Those percentages were maximum in each area. Opinions concerned meteorological phenomena were 86% and 53% in Youngju Dam and Seongduck Dam where area is surrounded by existing dam, but there was only 9% and 0% of opinions in Buhang Dam and Hantangang Dam where area is without existing dam nearby. The reformation methods which reflected the resident`s opinions were suggested on EIA in dam development projects. First of all, reliability and objectivity of the field of meteorological phenoma should be enhanced by scientific prediction of the phenomenon days. Secondly, techniques reducing uncertainty of various water quality prediction models ought to be developed and effectiveness of the reduction strategies in environmental impact should be quantified. Finally, the draft of EIA report should involve the detailed plans of migration and compensation`s procedures, criteria and measures to support.

Durability of automotive structures is a primary engineering consideration that is evaluated during a vehicle design and development. In addition, it is a basic expectation of consumers, who demand ever-increasing levels of quality and dependability. Automakers have developed corporate requirements for vehicle system durability which must be met before a product is delivered to the customer. To provide early predictions of vehicle durability, prior to the construction and testing of prototypes, it is necessary to predict the forces generated in the vehicle structure due to road inputs. This paper describes an application of the virtual proving ground? approach for vehicle durability load prediction for a vehicle on proving ground road surfaces. Correlation of the results of such a series of simulations will be described, and the modeling and simulation requirements to provide accurate simulations will be presented.
