Climate change is one of the most essential factors that should be taken into account for dam safety assessment. In this study infiltration/slope stability analyses are performed based on various flood scenarios. Using the results of the numerical analyses, a safety assessment is performed on a fill dam in Nak-Dong River, South Korea.

This paper introduces the recent development of GFRP-steel hybridized rebar and deals with an evaluation of its mechanical performance by authors. The objective of this study is to investigate tensile and bonding performance of the GFRP-steel hybridized rebar. The effect of hybridization on tensile properties was evaluated by comparing the results of tensile test with those of non-hybrid GFRP bars. The surface of the bar was designed and experimentally evaluated to obtain the sufficient bond strength in this study. To ensure the long-term durability of GFRP-steel hybridized rebar to corrosion resistance, the individual and combined effects of environmental conditions are currently under investigation.

The change of paradigm to performance-Based evaluation system for maintenance of SOC infrastructure is the effective way to invest limited financial. Selecting of the evaluation items is very important to develop a comprehensive performance assessment techniques and it determined by Delphi analysis. Also, to analyze the importance of the performance items, the AHP analysis was performed.

Recently, assessment of vulnerability of existing dam structures is a rising key issue in aspects of entire life year from design, construction to maintenance even in Korea due to more frequent earthquakes and effects of climate change. This study aims to develop a vulnerability assessment method for existing dam structures by using fragility analysis method based on 2-D FEM analyses, which can take into consideration various uncertainty information to dam structure safety assessment, and which may be incorporated into an integrated safety management platform under development by K-water.

Although the scope of Official Development Assistance(ODA) projects has been expanded to the energy and environmental sectors, many Green ODA projects have experienced difficulties in sustainable operation because of insufficient consideration on the real status of recipient countries. Selecting technology to apply is the first step on the ODA process, however, there has been lack of study on evaluation indicators, especially for waste-to-energy. Therefore, we have explored the evaluation indicators for waste-to-energy technologies selection based on the case of Phnom Penh capital city in Cambodia. The study was performed through literatures review, field trips, and interviewing local officials and experts. Finally, we have suggested following indicators: secure of raw materials (waste price, collection, waste quality), sustainable operation (construction and operation cost, land use, management ability), and market condition (prices of substitutes, demanders, required quality of products).

In this study, it is an object to develop a regression model for the estimation of TOC (total organic carbon) concentration using investigated data for three years from 2010 to 2012 in the Gam Stream unit watershed, and applied in 2009 to verify the applicability of the regression model. TOC and CODMn (chemical oxygen demand) were appeared to be derived the highest correlation. TOC was significantly correlated with 5 variables including BOD (biological oxygen demand), discharge, SS (suspended solids), Chl-a (chlorophyll a) and TP (total phosphorus) of p<0.01. As a result of PCA (principal component analysis) and FA (factor analysis), COD, TOC, SS, discharge, BOD and TP have been classified as a first factor. TOCe concentration was estimated using the model developed as an independent variable BOD5 and CODMn. R squared value between TOC and measurement TOC is 0.745 and 0.822, respectively. The independent variable were added step by step while removing lower importance variable. Based on the developed optimal model, R squared value between measurement value and estimation value for TOC was 0.852. It was found that multiple independent variables might be a better the estimation of TOC concentration using the regression model equation(in a given sites).

Although the frequency of use for community facilities in rural villages is growing as well as the importance of the facilities for urban-rural exchange is being highlighted, study on spatial location-analysis of the facilities for such multi-purpose is not so much. This study aims to find the spatial distribution forms of community facilities in rural villages such as community center and rural-pocket park through location-analysis, in order to provide available data for selecting location in the future. As the study area, Sojeong-myeon, Sejong Special City was selected. This study conducted GIS analysis for criteria of the location-evaluation model developed in this study. This study introduced the concept of time-distance for accessibility analysis. This paper also used linear-consecutive scoring method(LCSM) as a scoring method of criteria and Analytic Hierarchy Process(AHP) method for weighting values of criteria. The application results showed that the new model can generate the intensity of community facilities according to spatial distribution and accessibility from cities to the facilities.

In empirical studies on rural development projects, differentiation tends to be considered a strategy aimed at increasing the number of visitors. Rural development projects include the improvement of living environment, and the discussion about project goals and evaluation of project results are often focused on the aspect of rural tourism. Thus, subjective benefits of such projects for residents are omitted. This study examines the meaning of differentiation from the perspective of residents and explores the validity of the number of visitors and the possibility of reflecting residents' subjective score as evaluation indicators for a project. To achieve such an objective, this study uses survey data collected from 153 people in 38 comprehensive development projects in areas of Eup and Myeon, Korea. The results of this study show that differentiation is viewed as a by-product of positive improvement from a rural development project, from the perspective of residents. The effects of rural development are classified into two dimensions: socioeconomic effects and living environmental effects. Landscape improvement is included in the dimension of living environmental effects and an increase in the number of visitors is included in the dimension of socioeconomic effects. As such, they are confirmed to be the factors that determine the level of differentiation. For example, the increase in the number of visitors is confirmed to be a valid indicator of project success, in which two-dimensional characters are reflected. The level of differentiation evaluated by residents is a result of the workings of the above two factors. Unlike in previous studies, the possibility of evaluation based on the perception of residents is confirmed in the evaluation of results. When the level of differentiation is interpreted as the direct result of a project, the number of visitors has an impact on socioeconomic effects, and the project content of landscape improvement has an impact on living environmental effects. The goal of policy and residents is the same in terms of the effort residents may make in maximizing results of a project by themselves; thus, the government's goal is achieved even when a project is carried out under the autonomy of residents. Ultimately, the government should focus on providing conditions in which active citizen participation can not only occur but help to establish a policy direction, which subsequently strengthens the substantial rights of residents.

Since the 1970s, construction projects of SOC infrastructure have began rapidly. therefore, it is expected that the proportion of infrastructure using for more than 30 years will be increased in an instant. Because an aging infrastructure can greatly damage the national economy and people, maintenance of the infrastructure is essential. In this paper, performance-based evaluation items for maintenance of SOC(Social Overhead Capital) infrastructure and the process of calculating the weights of each items by using the AHP(Analytic Hierarchy Process) method are introduced.

This research project is to be carried out to propose the methodologies for improving the structural maintenance system by performance concepts consideration. The main contents of this project are performance(Safety, Durability, Serviceability etc) based management methodology. If this project is performed successfully, it is expected that the infrastructures can be effectively managed in Korea.
