This study was carried out to propose some useful advices for the improvement policy of the minor rural roads. From the case study on 5 country areas of Chonnam Province, it was ascertained that above a third of minor rural roads did not meet the statutory minimum level of their width, which means the necessity of substantial upgrade of road improvement works in rural areas.

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.

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.

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.

In this study, the maintenance problems were investigated through checking the creeks which were improved by close-to-nature river improvement technique. The characteristics of flow were measured at Changsa Creek in Suwon city. The computational results of numerical model with kinematic wave theory was evaluated through observation data about precipitation, velocity, and flow depth. Furthermore, SCS, Clark, and RRL models were compared to the actual observations. As a result, the kinematic wave theory's calculated peak time of discharge concentration occurred little earlier than the actual observation, but the tendency of hydrograph coincided with observation.

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.
