This study focused on urban regeneration projects to diversify projects methods. Since the enactment of legal redevelopment projects, they were concentrated on improving the physical environment and supplying housings. In this article, 12 cities' urban regeneration policies and projects will be examined to point out the characteristics of each regions via documentary studies and interview investigations. They could be divided into 3 groups by population and region. Finally, this article is intended to propose diversified regeneration methods depending on the regions and to address implications on the regeneration policies.

With the increased demand on housing quality and effective urban redevelopment, a new paradigm in reconstruction project is in need. Especially, the Urban and Residential Environment Improvement Law which initiated on July 1, 2003 has become a significant turning point. This code is expected to function as a consistent and systematic measure. This study will examine the code's major concepts and methods to progress reconstruction projects effectively. The application of construction management is examined carefully since the new code requires renewal project consulting firms to function as a professional complement rather than simply perform administration work, as in the past. Also, construction managing methods that can be related to renewal project consulting are examined and speculated. Lastly, methods to improve efficiency in reconstruction projects are introduced through case study and analysis on applicability and expected results.

The purpose of this article is to review the status of designation and preservation, management of national prehistoric sites and to suggest future applications. Prior to the discussion, the overall status of national prehistoric sites was reviewed. Specifically, the current status of designation, designated area, and distribution by region of national prehistoric sites according to the period and nature of the sites were examined in detail. Next, in order to understand the preservation and management of national prehistoric sites, I report the results of field trips to several sites, such as Geomdan-ri in Ulju, Songguk-ri in Buyeo, and Seoktaek-ri in Hongseong, and propose some measures for preservation, maintenance, and management of the remains. Finally, by referring to cases of US national historic sites such as protection, conservation, operation and management system and academic research project of cultural heritage, it is necessary to consider the need for a direction of the utilization that considers both socio-economic aspects as well as education and research on cultural heritage. The active use of cultural heritage can be a measure that leads to the continuous preservation and management of the sites, and ultimately will be a shortcut to increasing the value of national prehistoric sites.

Railroad rolling stock has long service life and a lot of maintenance cost running on rail by wear and vibration. And it is very important to get optimization of maintenance. This paper want to analyze rolling stock maintenance situation of KORAIL and find out its improvement methods. Especially, the purpose of this paper is to adopt the most effective maintenance period and methods to daily inspection which needs many maintenance manpower in rolling stock. Rolling stock has self-diagnosis function using computer system and the quality of rolling stock has much improved these days but current daily inspection repeat for short period routinely and it is very ineffective. Therefore, the paper adopt improved daily inspection period reflecting the characteristics of rolling stock, and want to secure reliability of rolling stock and minimize maintenance cost.

최근 전 세계적인 기후변화로 인한 풍수해 증가 추세와 금년 잦은 지진발생으로 인해 재난에 대한 관심이 증가하였다. 그러나 대부분의 재난대비는 도시지역에 기초하고 있기 때문에 농촌마을의 재난대비책을 마련하는 것 이 필요하다. 이에 본 연구에서는 농촌지역의 공간구조분석을 통하여 농촌지역 특성을 도출하였고, 농촌지역 특성에 따른 자연재해현황을 조사하여 공간구문론 분석을 통한 농촌마을 재난대비 공간정비 가이드라인을 개발하였다.

현재 4대강 유역개발과 하천 정비 등 관련된 대규모 토목공사가 진행되고 있다. 친환경적인 수자원 정비를 가능하게 하는 친환경 콘크리트 제품의 개발은 환경오염 방지 및 환경보전에 있어서 필수적이다. 현재 국내에서는 콘크리트에 다양한 자원 순환형 재료를 적용하고 있지만, 적극적 친환경 콘크리트의 연구는 아직 미미한 상태이다. 본 논문에서는 친환경적인 수자원 정비를 가능하게 하는 콘크리트의 필요성과 활용측면에 대해 논해 보고자 한다. 또한 국내외 관련 기술현황을 비교하여 현 콘크리트 제품 개발 산업에 적용방안을 제시하고자 한다.

가스터빈 발전은 연료를 연소하여 연소가스로 직접 터빈을 회전시켜 터빈에 연결된 발전기에 의해 발전하는 방식으로 연료로는 중유, 원유, 경유, 가스등을 사용한다. 주요설비는 공기압축기, 연소기, 터빈 및 발전기로 구성되며 이중 고온부는 연소기와 터빈이다. 가스터빈의 효율은 터빈입구온도(TIT : TBN INLET TEMP)에 의존하는데 현재까지 약 1,30$0^{\circ}C$ 급의 가스터빈이 운전중이며 앞으로 1,50$0^{\circ}C$ 급의 고효율 가스터빈에 도전하고 있으며 연소가스의 고온화는 고온부의 재료개발, 냉각기술, 코팅기법의 향상과 더불어 이루어질 수 있다. 가스터빈의 고온부 부품인 연소기, 터빈의 동익(Moving blade) 및 정익(Fixed blade) 재료로 초내열합금이 계속 개발중이며 또한 각 부품에 대한 공기냉각기술, 코팅재료 및 기법도 개발중이다. 그러나 현재 국내에서 가동중인 가스터빈은 빈번한 기동정지로 열 사이클에 의한 부품의 손상이 심각한 실정이므로 고효율 가스터빈 개발과 이에 대한 정비기술 개발이 병행하여야만 안정된 전기공급을 이룰 수 있다는 차원에서 가스터빈은 고온부품의 정비기술에 대한 그 현황과 전망에 대해 살펴보고자 한다.
