본 연구에서는 고해상도 기후시나리오를 이용하여 국내 대표 도시 지역인 서울특별시를 대상으로 기준기간(1971～2000년) 대비 미래기간 2020s (2011～2040년), 2050s (2041～2070년), 2080s (2071～2100년)의 기후변화에 따른 배수시스템의 영향을 평가하 였다. 이를 위해 과거 관측 강수량 자료는 기상청 관할 기상관측소와 자동기상관측망 자료를 이용하였으며, 기후변화 시나리오는 RegCM3과 Sub-BATS 기법을 통해 역학적 상세화된 5 × 5 km 해상도 기반의 시단위 강수량 자료를 생산하였다. 과거기간 대비 미래기간 확률강우량의 변동성을 비교한 결과 과거기간 대비 2080s의 확률강우량 증가율은 28～54%로 나타났으며, 특히 지속시간 3시간, 6시간, 24시간 확률강우량의 증가폭이 크게 나타났다. 또한 배수시스템의 기후변화 영향을 직접적으로 분석하기 위해 XP-SWMM을 이용하여 유출해석을 수행하였다. 평가 결과, 강우강도 증가로 인해 과거기간 대비 미래 3기간에 공릉1, 서초2, 신림4 배수분구의 침수발생 맨홀 수와 월류량이 크게 증가하였다. 이러한 결과는 현재 구축되어 있는 서울시 배수시스템은 기후변화 에 취약함을 나타내고 있으며, 이에 대응하기 위해 다양한 기후변화 적응대책이 요구됨을 의미한다.c

정부에서는 분리수거에 의한 폐기물 감량화를 유도하기 위하여 1995년부터 전국적으로 종량제를 실시하고 있으나, 수거 및 운반단계에서 발생되는 문제(폐기물 방치에 따른 악취 및 미관저해 등 환경위생적인 측면, 수거차량 이동에 따른 교통안전 등의 문제)를 크게 개선하지 못하고 있다. 이러한 문제를 해결하고자, 생활폐기물 수거운영방식으로 이미 유럽 및 일본 등에서 운영되고 있는 자동집하시스템이 도입되고 있다. 대전광역시는 서구 도안동에 신도시를 조성하면서 친환경 도시환경 조성과 쓰레기수거 경비 절감을 위해 총사업비 927억원을 투입해 자동집하시스템인 크린넷을 설치하여 운영하고 있으나, 제1집하장은 수변공원내에 주거지역과 근접하고 있어 집하장 주변에서 악취에 대한 민원이 많이 발생하고 있다. 제1집하장 주변 악취 민원해결을 위해서 기존의 악취방지시설을 보완하여 운영하고 있으나, 효과적인 대안이 수립되지 않은 실정이며, 현재 악취방지시설은 약액세정법으로 운영되고 있어 새로운 약품의 추가 주입과 기존 주입약품과의 주입량 비율을 조정함으로써 부지경계에서의 측정값은 배출허용기준 15이하는 충분히 만족하지만 큰 효과는 없어 이에 대한 민원을 해결하고자 한다. 악취는 감각공해로 사람마다 악취의 강도를 느끼는 정도가 다른 특징이 있어 민원소지가 많으므로 악취는 배출허용기준을 만족하더라도 복합악취희석배수 만큼 악취가 발생된다는 결과를 의미하므로 악취가 전혀 발생되지 않게 처리하는 방법은 기술적 한계와 더불어 과다한 소요비용이 발생될 수 있다. 따라서 악취를 현재보다 줄이기 위한 방법적용은 기술적 부분과 비용적 부분이 동시에 검토되어야 하며 다음과 같은 방안을 제시할 수 있다. 1) 기존에 설치되어 있는 악취방지시설의 운전조건 수정을 통해(일반 물세정이 아닌 약액세정을 실시, 일반 활성탄을 첨착활성탄으로 교체) 보다 높은 악취제거 효율을 기대하고, 2) 기존 방지시설 운전조건을 개선한 후에도 사업장 주변에서 악취민원이 발생한다면 최종배출가스를 하수 차집관로로 유입하여 처리하도록 하며, 3) 장기적인 방안으로 기존의 악취방지시설로 악취문제를 해결하기 어렵다면 신규 악취방지시설(촉매연소)을 설치할 수 있다.

The grid-based water balance of watershed scale was assessed in the mountainous area of Pyosun catchment in Jeju Island after analyzing precipitation, evapotranspiration, and runoff from January 2008 to December 2013. The existing results of direct runoff, evapotranspirtion, and groundwater recharge comparing to precipitation were presented 22.0%, 25.6%, and 52.4%, respectively, in Pyosun catchment. However, this study indicated each component shows 14.5%, 24.2%, and 61.0%, respectively, in the mountainous area of Pyosun catchment. Therefore, groundwater recharge rate in the mountainous area appears higher than 10% comparing to the overall catchment. It would be analyzed that the amount of direct runoff is relatively small. Moreover, this difference could be generated because of the spatial discontinuities in the process of estimating the total amount of precipitation in the mountainous area. Therefore, the grid-based spatial analysis to maximize the spatial continuity would be useful for providing a more reasonable result when the total amount of water resources are evaluated in mountainous areas in the future.

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.

This study classifies the types of spatio-functional differentiation in Korean island areas and analyses typical characters and suggests the development directions by each type. Eup/Myeon-level island areas are classified as six types by the factor analysis and the cluster analysis. First type is the traditional rural center. This type puts emphasis on maintaining phase as the central space and has to maximize development potential of the whole of settlement zone. Second type is the specialized region in manufacturing industry and the qualitative mutual growth of regional industries is able to be suggested. Third type is the specialized region in the neighborhood service provision. This type needs to devise the plan for utilizing potential customers actively and developing into the region specialized in tourism industry. Fourth type is the specialized region in tourism-support service functions. This type has to promote differentiated policies for maintaining amenity infra or value of countryside capital and preservation and utilization of resources by regional features. Fifth type is the fishing industry-dominated region. This type has to promote sustainable fishery development through the policy reflecting regional features and condition. Finally, sixth type is the sluggish region dominated with the traditional agriculture and fishery. This type is needed to aim at developing into the new food production base having the advantage of clean environment by strengthening support in specialized agro-fishery products. The existing researches on spatio-functional differentiation were mostly discussed with respect to land development, but this study highlights the difference in deal with the island areas distinguished from the condition of industry.

To analysis of virus free sweetpotato effect, 5 virus free sweetpotato and virus normal sweetpotato varieties were planted in 5 different regions at 2010 year. The average yields of virus free sweetpotato are showed different results according to regions. Sinjami which cultivated at Iksan were increased maximum 68% compare to normal. However, Sinjami which cultivated in Hamyang were decreased yield 11% compare to normal. Analysis of tuber formation ratio of Sinjami, Yenhwangmi, Singeonmi which cultivated in Nonsan were decreased tuber number compare to normal. However, 3 varieties were all increased on Average storage root weight and yield of marketable storage root. In the results of analysis of marketable storage root according to cultivated regions and varieties, all varieties except Sinjami which cultivated in Hamyang were increased yield. Also, quality of virus free sweetpotato were enhanced 7 to 9 compare to virus infected sweet potato which showing average 3. Contents of starch between virus free and virus infected sweetpotato were not affected by virus. Virus free sweetpotato were more increased starch products according to increased total production yield. Also, Brix° (%) was not showing difference between virus free and virus infected sweetpotatoes. In this experiment, Virus free sweetpotato are enhanced production yields and quality. Therefore, we suggested that virus free sweetpotato is one of the methods to reduce damage by sweetpotato virus.

Centennial- to millennial-scale climate change since the last glacial needs to be revealed to improve the overall predictability of future environmental change. Special attention has been paid to short-term climate oscillations because they usually occurred rapidly enough to cause noticeable change in the average expected lifespan of human. Recently, short-term climate change during the late last glacial was successfully reconstructed from Hanon maar paleolake in Jeju island. In this study, centennial- to millennial-scale climate signals transferred via atmospheric teleconnection were detected for the first time in South Korea. Possible future presence of abrupt climate shifts such as Younger Dryas or 8.2 ka event would not seriously influence the Korean peninsula, especially not Jeju island, due to the Kuroshio warm currents. The study of climate variabilities in Korea could provide essential paleoclimatic information for the entire East Asian monsoon region since the climate of the Korean peninsula is driven significantly by coupled land-atmosphere-ocean dynamics.

As environmental concerns including climate change drive the strong regulations for car exhaust emissions, electric vehicles attract the public eye. The purpose of this study is to identify rural areas vulnerable for charging infrastructures based on the spatial distributions of the current gas stations and provide the target dissemination rates for promoting electric cars. In addition, we develop various scenarios for finding optimal way to expand the charging infrastructures through the administrative districts data including 11,677 gas stations, the number of whole national gas stations. Gas stations for charging infrastructures are randomly selected using the Monte Carlo Simulation (MCS) method. Evaluation criteria for vulnerability assessment include five considering the characteristic of rural areas. The optimal penetration rate is determined to 21% in rural areas considering dissemination efficiency. To reduce the vulnerability, the charging systems should be strategically installed in rural areas considering geographical characteristics and regional EV demands.
