    Abstract PDF
    This study, focusing on the area expansion of limestone mines, identifies the problems ofEnvironmental Impact Assessment(EIA) and what impact the current problems exert on anothermines developing process. The legal relations analysis reveals that the Management of MountainousDistricts Act and other related laws effect on EIA process, especially the case of area expansion oflimestone mines excluded from EIA. However, these problems can create mismatch with the policygoal of EIA system and have a negative impact on the environment in the future. A series of indepthinterviews with managers in related agencies found that those agencies have been unawareof the seriousness of the problem. Without any strategy, negative result made by developmentactivities would get more serious and sustainable development may not be possible at all. In orderto solve these problems, government should modify the current interdependent legal provisionand create the incentive structure to participate actively related agency in the EIA system.

    Analysis of Economical efficiency for renewable energy in Steam Power Plant

    Choi, Kyoung-sik | 2014, 23(1) | pp.11~17 | number of Cited : 3
    Abstract PDF
    Since the Renewable Portfolio Standard (RPS) would be started in 2012, the use of renewableenergy should be 11% of total energy use including bio-fuel in 2030. The economic efficiency forrenewable energy in B power plant was considered with the bio-diesel, wind power and solarpower. The Net Present Value (NPV) and Benefit/Cost Ratio(BC) were used for the economicefficiency with the cost and benefit analysis. In case of bio-diesel, the cost resulted from the fuelconversion and the benefit would be created with trade and environmental improvement. Withregard to wind power and solar power, the construction cost would be required and benefit factorswould be same as the bio-diesel. The wind power was the best of economic efficiency of renewableenergy as the results of NPV and BC ratio. Whereas, the market of wind power was very popularand the techniques of wind power has been developing rapidly.

    Analysis of Relationship Between Water Quality Parameters with Land Use in Yeongsan River Basin

    박진환 , 문명진 , Kapsoon Kim | 2014, 23(1) | pp.19~27 | number of Cited : 10
    Abstract PDF
    The purpose of this study is to provide a base line data to improve the water quality in theYeongsan River basin. As the major factor that affects the water quality of Yeongsan River isnonpoint pollution source, in order to find a resolve to improve the quality, a study was conductedto identify the correlation between the stream water quality and that of the land use. The studyshowed that the concentration of the contents in the water from the agricultural land environmentwas found to be higher as oppose to that found in the content of the water from the forest land. Asa result, it can be deducted that agricultural land deteriorates water quality whereas that of theforest land is of much better quality. Therefore, it is highly recommended to take advancedimproved care of agricultural land close to a water source to improve the quality of YeongsanRiver basin.

    Suggestion of assessment height for noise measurement according to the vertical radiation characteristics of railway noise

    조준호 , 장강석 | 2014, 23(1) | pp.29~37 | number of Cited : 2
    Abstract PDF
    Exact and precise noise measurement is the basis for the reduction measure R&D, impactassessment and prediction modeling for railway noise. In this study, research trend as well asnational and international noise measurement standard are investigated. For the estimation ofvertical radiation characteristics of railway noise, specially devised zig was used. From the noisemeasurement and analysis, exact noise height radiated from the railway was characterized. Theobtained results will be used for the suggestion of the height of microphone position of railwaynoise measurements.

    Local Analysis of the spatial characteristics of urban flooding areas using GWR

    심준석 , KIM JISOOK , LEE,SUNG-HO | 2014, 23(1) | pp.39~50 | number of Cited : 5
    Abstract PDF
    In recent years, the frequency and scale of the natural disasters are growing rapidly due to the global climate change. In case of the urban flooding, high-density of population and infrastructure has caused the more intensive damages. In this study, we analyzed the spatial characteristics of urban flooding damage factors using GWR(Geographically Weighted Regression) for effective disaster prevention and then, classified the causes of the flood damage by spatial characteristics. The damage factors applied consists of natural variables such as the poor drainage area, the distance from the river, elevation and slope, and anthropogenic variables such as the impervious surface area, urbanized area, and infrastructure area, which are selected by literature review. This study carried out the comparative analysis between OLS(Ordinary Least Square) and GWR model for identifying spatial non-stationarity and spatial autocorrelation, and in the results, GWR model has higher explanation power than OLS model. As a result, it appears that there are some differences between each of the flood damage areas depending on the variables. We conclude that the establishment of disaster prevention plan for urban flooding area should reflect the spatial characteristics of the damaged areas. This study provides an improved understandings of the causes of urban flood damages, which can be diverse according to their own spatial characteristics.

    Official Development Assistance and Environmental Assessment

    Lee, Jong-Ho | 2014, 23(1) | pp.51~65 | number of Cited : 5
    Abstract PDF
    ODA projects such as multi-purpose dam, industrial complex, road construction etc. haveresulted in environmental damage and resident relocation including destruction of site of living. Even the grandiose developments as ODA projects have made clear the value clashes betweendevelopment and environmental conservation, and have brought about conflicts between publicinterests and public environmental right, and the discordance between public interests and privateproperty rights in the recipient country. This study summarizes and analyses the Korea’s ODA projects and will suggest the publicparticipation and governance system based on Saemaul Movement, Strategic EnvironmentalAssessment and Environmental Impact Assessment based on the guideline of OECD DAC, andemphasize Strategic Environmental Assessment and Social Impact Assessment in the procedureof ODA projects. In the future the ODA project should be implemented for the overcome of poverty and responseto climate change based on the experience and trial and errors of Korea’s compact growth andpast ODA projects.

    A Study of Non-point Source Reduction Efficiency by Constructed Wetland installed in Flood Pumping Station

    chun suk young , KIM JI TAE , 이일국 and 1 other persons | 2014, 23(1) | pp.67~74 | number of Cited : 1
    Abstract PDF
    The aim of this study was evaluated the effects of total rainfall, rainfall intensity and antecedentdry days and identify the correlation analysis with the EMC removal efficiency, in order to providean understanding of the operation and maintenance factors of constructed wetland in floodpumping station. This study was conducted total of 20 monitoring in a catchment(326.2 ha) ofconstructed wetland in Ga-un flood pumping station located at the downstream of the Wang-sukstream. The determined EMC removal efficiencies were 36.04±9.45% for BOD, 38.50±13.50% forCODMn, 34.34±13.05% for TN and 34.22±14.27% for TP, respectively. These results showed that thepollutants concentration and EMC were reduced while passing through the constructed wetland. In the correlation analysis, the highly correlations with EMC removal efficiency of BOD and CODMnwere observed for total rainfall and rainfall intensity (P<0.05). However, the correlations were notfound with TN and TP for rainfall variables.
