  • This study analyzed opinions of specialists checking of industrial environment, analysis of bid guideline to select environment friendly railway corridor and choose weight factors. Thus, 7 major categories were extracted from 20 EIA categories and essential supplement request items for environment friendly railway corridor selection. To select environment friendly railway corridors, many alternatives should be compared and the assessment of each alternative must be carried out on the basis of these 7 categories. To solve this problem, the selected method was AHP which simplifies the complex problems utilizing hierarchy, quantifying qualitative problems through 1:1 comparison, and extracting objective conclusions by maintaining consistency. As a result, a GUI-based program was developed which provides basic values of weighted parameters of each category defined by specialists, and a quantification of detailed assessment guidelines to ensures consistency.

  • 최근 세계적으로 환경문제에 대한 인식이 새롭게 변화하면서 산업발전을 지향하는 과정에서 과거의 산업개발 기조를 지양하고 환경 친화적인 산업구조로 변화하기 위해 규제강화 및 자구책 등을 모색하고 있다. 정책적 제도 마련과 더불어 환경 유해물질을 처리할 수 있는 새로운 기술 개발에 총력을 기울이고 있으며, 오존층의 파괴 및 인체에 해로운 영향을 미치는 것으로 알려져 있는 휘발성유기화합물질(Volatile Organic Compounds, VOC)에 대한 처리 방안도 중요한 문제로 대두되고 있는 실정이다. (중략)

  • In the area of such a nature-friendly stream improvement, it is not established yet which engineering method is suitable for stream environment, due to lack of technology. Therefore, although nature-friendly stream improvement was done with expensive engineering method, the effect has not been fully confirmed, which results from the absence of overall valuation tool of stream improvement. In this regard, it is necessary to develop and apply comprehensive and diverse valuation methods covering stream functions to the analysis of stream improvement. In this study, we collected data from years' of monitoring on the Gyeongcheon river, which is located in Sunchang-eup, Jeollabuk-do and recently underwent an nature-friendly stream improvement work. Based on the data, we developed a series of valuation methods such as stream naturalness evaluation, life cycle evaluation, amenity evaluation, and economic benefit analysis to consider the environmental function of stream from a comprehensive perspective. Stream naturalness evaluation is a quantitative analysis of how natural a stream is, and includes additional valuation items such as ecosystem and water quality for the purpose of overall valuation, unlike existing research focusing on physical elements and structural characteristics of a stream. We developed a method of stream valuation with life cycle assessment to river reorganization project. Amenity evaluation method was developed as a means to analyze residents' satisfaction with stream improvement through questionnaires. Economic benefit analysis was developed as a means to determine the attributes of environmental water supply, ecosystem, river maintenance, and water quality and predict economic benefits using contingent valuation method (CVM) and multi-attribute utility analysis (MAUA) method in order to analyze economic benefits brought in by stream improvement. It is considered that the four methods developed in this study make possible to conduct an overall and quantitative analysis of stream improvement.

  • 현대는 인간의 복지와 환경보호의 양면을 중요하게 여기는 시대이다. 생물을 담보로 생산성을 추구하는 모든 산업이 환경에 친화적이면서 인간복지에 기여하는 산업으로 접목되기를 강요하고 있는 시대다. 이러한 현상은 범세계적인 추세다. 이러한 대전제에 부응한 산업이 되었을 때 얻게되는 수익에서 수익의 합리성을 찾을 수 있고 지속적인 성장이 기대되는 산업으로 보장받을 수 있기 때문인 것으로 생각된다. (중략)

  • The purpose of this study is modeling a user-friendly Korean-Japanese thesaurus for internet circumstances. The methodology had two steps: first, the problems were analyzed when multilingual thesaurus is constructed, with review of various multilingual thesauri and interview with multilingual thesaurus constructor in Korea and Japan. Second, collaborative tags were analyzed to differentiate cultural/linguistic background from word usage pattern. As a result, searching thesaurus model was suggested and applied to develop a user-friendly Korean-Japanese thesaurus.

  • 이미 알려진 바와 같이 차세대 차량에 채용될 동력 시스템의 연구개발이 배출가스 규제에 대한 배기 성능의 획기적 개선에 집중되고 있는 한편, 포괄적 친환경 차량 개발 또한 일반의 관심을 끌고 있다. 현재에 이르기까지 배출가스 규제치 즉, 대기로 배출되는 질소산화물(NOx), 입자상물질(Particulate Matter, PM) 및 미연탄화수소 등에 대한 정량적 규제치의 만족여부가 차량의 친환경 여부를 가리는 척도로 주로 인식되어 왔으나, 금후 보다 본격적으로 완성차량 조립을 위한 전 제품의 제조과정으로부터 차량 폐기까지를 총괄한 포괄적 환경 영향 평가가 필수 불가결한 요소로 등장하리라 예측된다.
