주택건설과 대규모 개발사업으로 인해 골재부족이 심화되면서 하천정비공사에서 골재채취가 주요한 사업이 되고 있다. 하지만 무분별한 골재채취는 하천생태계를 파괴시키는 원인이 된다. 본 연구는 하천에서 골재를 채취할 때 수생태계에 미치는 영향과 골재채취를 중지하고 휴식년제를 취할 때의 수생태계에 미치는 영향을 서로 비교${\cdot}$분석함으로서 하천골재 채취가 환경에 미치는 영향을 분석하였다. 연구방법은 수리학적 분석, 수질분석, 생태학적 분석을 이용하였다. 연구대상지역은 영산강의 일부구간으로 현재 이 구간은 골재채취공사가 진행중인 지역이다. 하상변동을 수치해석으로 모의한 결과 하상은 골재채취후 안정적으로 유지될 것으로 분석되었으며 골재채취가 수질에 미치는 영향은 그리 크지 않았고 단지 부유사(SS)가 약간 증가하였다. 생태학적 조사 결과 어류, 포유류, 양서류, 파충류와 조류는 공사로 인한 영향을 많이 받고 있는 것으로 분석되었다. 본 연구의 결과는 골재채취 사업에 따른 환경영향평가 및 사전환경성 검토에 활용될 수 있고, 하천공사와 수공구조물의 설계 및 유지관리 등에도 활용될 수 있을 것이다.

Providers haven't recently had a flexible construction cost estimation system to meet various needs of consumers about public housing. So the subject of this study is to estimate construction cost reasonably in early project stage of public housing and then develop reliable means which is able to support construction cost management and establish a adequate funding investment plan as a provider. In this study, Regression analysis was performed by the case on 20 public apartment complex which were designed from the first half of 2007 to the first half of 2008. A total construction cost of construction, civil engineering, machinery, elevator, land scape, electricity and communication work was used as one sample for increasing explanation and representativeness of the case. In addition, The total construction cost which is devided into design, contract and completion cost was variously analysed for increasing relevance of model and actual utilization. The result of estimation model based on a total construction cost set up completion and design cost showed that error rate is within 2%, which is a excellent result. The estimation model of the construction cost developed by this study is expected to estimate approximate construction cost which is adjacent real construction cost in early stage of the project by using some data.

This paper proposed an effect analysis method that meets the characteristics and purposes of the revitalization project for old industrial complexes, and quantified the economical effects about the project in Jeollabuk-do by case analysis. The problems on the existing effect analysis about revitalization project for old industrial complexes, estimated as transportation benefits on the main entrance roads plan and the increased rent benefits on the internal roads and other plans, were examined. In addition, the land use plan ratio on the old industrial complexes compared to the averages, and the surveys to the residential company were conducted. And this paper finally proposed an effect analysis methodology for the revitalization project for old Industrial Complexes in consideration of the increase in the operation rate and the added values through the conversion to high value-added industrial sectors. It was analyzed that new value added of KRW 743,278 million can be generated for next 30 years when the revitalization project for old Industrial Complexes in Jeollabuk-do is implemented.

Kimpo international airport logistics complex had been the most busiest airfreight gateway in Korea during last century but, after the grand open of Incheon international airport in 2001, it had lost its major role as a national airfreight hub facilities. However, owing to its locational advantages in Seoul metropolitan area. Kimpo airport logistics park still acts like an urban logistics distribution center in these days. Caused by the KAC's profit oriented policies, the Kimpo airport logistics park's public function as an urban distribution center might be curtailed in the future. Therefore, several laws and ordinances related to national and regional logistics strategies should be modified to prevent it.

This study analyzes the validity of the type classification of the type and design changes of apartment landscaping planting construction design changes that were completed in the private sector, efficiently manages the design changes that are displayed over landscaping planting work in general in the future, and performs research by placing the object underlying the presentation. The results are as follows. First, the percentage that occurred in the planting construction of design changes that have occurred in the apartment landscaping construction was carried out in the private sector and accounted for 61.8%. This indicates that part of the planting is a major design change. Second, as the cause of such a design change to be those associated with the field conditions such as lack of main construction period. In particular, due to a change in oral, appeared 7-48 times design changes of one review design change approval is complex, design changes of planting construction had shown a feature that occurs in multiple simultaneous. Third, the 7 types of Design Changes in planting design were delineated as 'design changes for consideration of the user', 'design changes for image improvement', 'design changes for ease of maintenance', 'design changes due to the mismatch of design statement', 'design changes due to the relationship with the engineering species of other', 'design changes due to lack of field study', and 'design changes due to the consideration of feasibility.' Fourth, 'design changes for consideration of the user' and 'design changes for image improvement' were found in more than half of the frequency of the overall changes. This differed from the results shown in public corporations. Fifth, if planting construction design change process, private companies, it was found that is showing the approval of the practice after the previous construction of the construction cost savings due to construction time. However, in the case of a public corporation, these exhibited a different aspect from the private sector and show a design change procedure that reflects the changes after the design change events in the field have occurred. The above results, the type of landscaping works in planting design change of public enterprises, regardless of the private sector, is the same in the seven types, the main reason of and procedures for design changes, indicating that there are other respects. In design change, it may be desirable to apply becomes liquidity rationality and efficiency of the dimension, depending on the nature of the landscape construction.

This study aims to examine the distinctions in evaluation index items between overseas and domestic ecological area-related systems, derive analytical indicators, and assess recently completed apartment complexes before and after the implementation of overall ecological area ratios. The objective is to analyse variances in the application of ecological area characteristics, categorizing them into ecological area analysis indicators and presenting their implications. The spatial scope covers completed apartment complexes in both metropolitan and non-metropolitan areas. Thirty-six completed apartment complexes were selected for analysis, and basic ecological area data were compiled. Subsequently, the data was utilized to categorize three analysis indicators-ecological area ratio, ecological area diversity, and ecological area connectivity-by metropolitan and non-metropolitan areas, as well as by type of apartment complex (sale housing versus rental housing) and size (large-scale, medium-scale, and small-scale). Results of the analysis indicate higher ecological area ratios and greater diversity in ecological area spatial types in metropolitan areas compared to non-metropolitan areas, and in pre-sale housing complexes compared to rental housing complexes. Mediumand large-scale apartment complexes exhibit higher ecological area ratios, with ecological area diversity being more pronounced. Ecological area connectivity reveals more numerous and varied connection points and types in metropolitan areas than in non-metropolitan areas. Implications of this study suggest that large-scale development should prioritize securing ecological area ratios and diversity in apartment complexes. Enhancing biodiversity necessitates establishing connections within and beyond the ecological area network of the complex. Future research should focus on linking the ecological area network within the complex.

단순한 공항 역할을 벗어나 복합문화위락단지로 거듭나고 있는 김포공항에 3차에 걸친 조명분야 ESCO사업이 착륙했다. 한국공항공사 전기통신처는 국내선 청사의 2만5천개에 달하는 조명기기를 지난 99년 1월 고효율에너지기자재로 교체하는 ESCO사업을 실시한 데 이어 다른곳에도 두 차례 추가ESCO사업을 추진할 정도로 효율적이고도 적극적인 에너지절감활동을 전개해나가고 있다.
