        In 2013, International Agency for Research on Cancer (IARC) concluded that outdoor air pollution is carcinogenic to humans, with the particulate matter component of air pollution most closely associated with sufficient evidence of increased cancer incidence by exposure to particulate matter component of air pollution. Motor vehicles are one of a major emission sources of fine particle (PM2.5) in urban areas. A large number of epidemiological studies have reported a positive association of morbidity or mortality with distance from the roadside. We conducted this study to assess the association of PM2.5 concentrations measured at roadside hotspots with those at adjacent residential sites using real-time PM2.5 monitors. We conducted real-time PM2.5 measurements for rush hour periods (08:00∼10:00 and 18:00∼20:00) at 9 roadside air monitoring Hotspot sites in metropolitan Seoul over 3 weeks from October 1 to 21, 2013. Simultaneous measurements were conducted in residential sites within a 100 m radius from each roadside air monitoring site. A SidePak AM510 was used for the real-time PM2.5 measurements. Medians of roadside PM2.5 concentrations ranged from 9.8 μg/m3 to 38.3 μg/m3, while corresponding median values at adjacent residential sites ranged from 4.4 μg/m3 to 37.3 μg/m3. PM2.5 concentrations of residential sites were 0.97 times of hotspot roadside sites. Distributions of PM2.5 concentrations in roadside and residential areas were also very similar. Real-time PM2.5 concentrations at residential sites, (100 m adjacent), showed similar levels to those at roadside sites. Increasing the distance between roadside and residential sites, if needed, should be considered to protect urban resident populations from PM2.5 emitted by traffic related sources.

        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).

        Global increase in energy consumption has been known to cause the depletion of fossil fuels, and results in the increase of coal and oil price. Recently, waste to energy policy has received attention more and more, Korea imports approximately 97% of its total energy consumed, and there is an urgent necessity for the development of alternative energy source. Domestic waste management policy aims at zero waste community, which can be explained as the concept of 4R. The 4R consists of existing 3R (Reduce, Reuse and Recycle) and Recovery policies. Conversion of waste to energy, a form of renewable energy, has been known as an effective alternative for the increasing energy crisis. In this study, waste wood generated in D city was investigated as one of the alternative energy source. Expecially, the conversion of waste wood to solid refuse fuel (SRF) as an energy source was focused on. As an initial step to evaluate the applicability of waste wood as the alternative energy source, the waste wood sample were characterized by a proximate analysis and element and heavy metal contents analyses. In addition, heating values of the waste wood were calculated by presumption equation and Dulong's equation, and measured by bomb calorimeter. In summary, waste wood can be considered as one of the alternatives for effective energy source by meeting Korea standards for the quality and grade of SRF such as in lowheating values, contents of moisture, sulfur, and chlorine, and heavy metal contents

        Along the increases of incineration bottom ashes emitted from the municipal solid waste incinerator, the issues, such as increased treatment costs, environmental problems and lack of land area for incineration treatment facility have raised. Therefore, this study was performed to analyze the incineration bottom ash to seek how to recycle the resources. The particles of bottom ash discharged as municipal solid wastes are not even and composed of inorganic substances such as iron and non-metals; in this study, therefore, the bottom ash are used as the basic data for the purpose of resource recycle. In this study, the waste incineration bottom ash emitted from the incineration treatment facility located in city C were analyzed. About 100 tons of municipal solid waste are incinerated in this facility on a daily basis. The particle size, XRF, TGA and ICP were analyzed for bottom ash. A LA-950(Laser Scattering Particle Size Analyzer) was used to perform a particle size analysis and as a result, the particle diameter of a large range was distributed and the particle diameter was shown to be wide so not evenly distributed. The distribution of particle diameter for each sample was shown to be inconsistent. XRF used an EDX-750 (Shimazu) to analyze the chemical components and as a result, the key components contained in the bottom ash included CO2, CaO, SiO2, Al2O3, B2O3, etc. The analysis revealed that CaO contained to be lower than other area. TGA / DSC 1 / 1600 LF(Mettler-Toledo AG) were used to analyze TGA and the heating rate of 10℃/min was applied up to the maximum temperature 1200℃. As a result, the sample of incineration bottom ash showed its significant reaction at around 700℃. In general, when temperature of bottom ash starts raising, the moisture started to evaporate at around 100℃ while a significant decline is observed in weight. However in this study, no significant change was observed around 100℃ followed by the pre-processed and bottom ash. ICP used 820 ICP-MS (Bruker, Germany) to analyze the heavy metal - As, Cd, Cr, Cu, Hg and Pb. 3 different bottom ash were divided into 3 samples and as a result, the average concentration of each substance was analyzed as As 0.0049ppm and Cu 0.006ppm, whereas the concentrations of Cd, Cr, Hg and Pb were observed to be less than the quantization limit; therefore, the concentrations of all 6 items were shown to be less than the hazardous level of the specified wastes.

        This study identified concentrations, toxicities, and sources of polycylic aromatic hydrocarbons (PAHs) and heavy metals in roadside sediment from different areas of Gwangju City. Samples were collected from 13 sites of heavy traffic area (TA), downtown area (DA) and park area (PA) during February and June in 2014. The results showed a wide distribution range of PAHs concentrations between 0.139 mg/kg and 1.740 mg/kg. The highest concentration of PAHs appeared in heavy traffic area (TA). The toxic equivalent quotients (TEQs) of PAHs in the roadside sediment ranged from 27 ng/g to 159 ng/g. The TEQs and PAHs ratio of heavy traffic area and downtown area was 9.1 to 11.0%, respectively. The contributions from potential sources to PAHs in roadside sediment were estimated by the principal component analysis (PCA) and diagnostic ratios between PAHs. Vehicular (gasoline and diesel engine) emissions were found to the predominant contributor of PAHs. The concentrations of heavy metals were highest in the heavy traffic areas. The correlation analysis among traffic intensity and heavy metals, showed that AADT correlates very strongly with Cr, Cu and Pb concentrations. From the results of pollution index (PI) calculation for roadside sediment, heavy traffic area was severly polluted by heavy metals such as Cr, Cu, Pb and Zn. Contaminants in roadside sediment were found to be much affected by the vehicles. Therefore, roadside deposited sediments would be expected to be managedon a regular basis.

        Climate change has been a global issue since the 19th century. The increase in rainfall variability, which covers the increase in the earth’s total precipitation, will definitely lead to frequent and more severe flood disasters. As the damage increases year after year with floods as the most chronic and costly disaster among these hazards, Korea has to improve its technological responses and countermeasures to better visualize the hazards brought about by such disasters. Gunsan City ranked number eight in the country’s most susceptible region to floods. From 2004 to 2013, Korea has experienced a total of 174 flood disasters which were estimated to cost USD 7.32 billion. But reports showed that the total expenditure of the government amounted to 1.4 times the estimated losses and damages and the private companies have spent twice the said estimated amount. To summarize, the post-disaster loss and damage reports showed underestimated values. This study aims to develop a semi-parametric geographically weighted regression which can implement a flood damage estimation model of Gunsan City. The model building process include parameters like flood depth, flood duration, inundated area, family income and land price. The datasets are composed of both untransformed and transformed data (using Box-Cox Method). Both Ordinary Least Squares (OLS) Regression and Geographically Weighted Regression (GWR) were evaluated in this study, but the search for best fit resulted to the use of GWR.

However, reports showed that the total expenditure of the government amounted to 1.4 times the estimated losses and damages and the private companies have spent twice the said estimated amount. To summarize, the post-disaster loss and damage reports showed underestimated values. In this regard, the National Emergency Management Agency (NEMA), the government institution designated to assess and analyze the damages and losses as well as evaluate the disaster risks of the said areas in accordance to their disaster risk management plans, are now developing a new estimating method for damages and losses. This study aims to develop flood damage functions that will estimate the flood damages of Gunsan City based on the building type: residential, commercial and agricultural facilities, by utilizing the Ordinary Least Squares Regression and later on, the Geographically Weighted Regression. The model building process includes flood depth, flood duration, inundated area, family income and land price as the parameter variables. Due to normality issue, the datasets were transformed through Box-Cox Method. Both Ordinary Least Squares (OLS) Regression and Geographically Weighted Regression (GWR) were evaluated in this study, but the search for ‘best fit’ resulted to the use of GWR.
