  • This study was focused on the evaluation of Nanjido landfill site by leachate analysis. Several parameters, for example pH, BOD, $COD_{Mn},\;COD_{Cr}$, SS, TP, $NH_3-N$, Color, were selected as major leachate quality parameters. $BOD/COD_{Cr}$. was used to estimate the biodegradable portion in organic matter. Samples were collected at the leachate storage wells and leachate treatment facility inflow in each quarter of 2003. The results were as follows : 1. Inflow quality of treatment plant in 2003 was analysed as $pH\;7.3\~8.0,\;BOD\;12.4\~30.0mg/L,\;COD_{Mn}\;101.2\~130.3mg/L,\;COD_{Cr}\;122.5\~238.0mg/L,\;SS\;16.1\~115.3mg/L$, $T-P\;0.27\~0.80mg/L,\;NH_3-N\;208.0\~~354.0mg/L$, Color $110.3\~129.0$ unit. 2. $BOD/COD_{Cr}$ of inflow ranged between $0.07\~0.16$ indicating that the landfill had the properties of old-fill and organic portion in leachate was mostly persistent organic matter. 3. Though concentrations of BOD, COD, $NH_3-N$, Color in leachate storage wells were mostly higher in first landfill than in second landfill, $BOD/COD_{Cr}$ ranging from 0.03 to 0.20, showed reversely. 4. Correlation coefficient$(R^2)$ between color and other parameters related to organic matter showed mostly above 0.7 and especially highest value with $COD_{Mn}$ of 0.7985.

  • 석탄화력발전소 온배수열 활용하여 발전소 인근지역 시설농업에 난방열을 공급하는 사업의 배관투자비는 설치거리에 비례하여 증가하고 발전소와 떨어진 거리는 경제성 확보에 문제를 낳는다. 또한, 설치거리가 짧은 경우는 난방열 수요 확보가 어려워 경제성 확보의 문제가 있을 수 있다. 본 연구에서는 기준 열배관로 신설길이 1 km에 대한 경제성 평가와 열배관로 신설길이 변동에 따른 민감도를 정부지원금 수준, 난방열 수요량 수준과 정부지원금 증가에 따른 경제성 확보가능 열배관로 신설거리 수준에서 분석하였다. 분석결과 기준 열배관로 신설길이에서는 NPV 131백만원, IRR 15.73%로 경제성을 확보 가능한 것으로 평가되었다. 다만, 민감도 분석결과 열배관로 신설길이가 2.6 km를 초과하는 경우 NPV가 음수로 나타나 경제성을 확보하지 못하는 것으로 분석되었다. 결과적으로 초기투자비의 50%를 정부가 지원하는 경우 5.3 km, 80%를 지원하는 경우 11.4 km 이내에서 경제성을 확보하는 것으로 분석되었다. 기준 열배관로 신설길이에서는 난방열 수요가 기준 열수요 대비 62% 수준 이하로 감소하는 경우 경제성이 없으며, 열배관로 신설길이가 2 km에서는 기준 열수요 대비 14%만 감소하여도 경제성을 확보하지 못하는 것으로 분석되었다. 초기투자비대비 정부지원금 비율이 증가하는 경우 열배관로 신설거리의 탄력성이 증가하여, 열수요 1단위에서 부담하는 시설투자비인 고정비가 감소한다. 이는 단위당 생산원가가 감소하는 효과로 나타나고 시설농업에 더 저렴한 수준으로 열을 공급할 수 있음을 의미한다. 정부지원금은 열배관로 신설거리가 증가하는 효과로 경제성이 확보될 수 있고, 열수요 개발가능 범위 증가에 따라 추가적인 경제성을 확보할 수 있다. 초기투자비 대비 정부지원금 비율이 증가할수록 생산단가 감소로 인한 시설농가의 에너지비용 또한 감소할 것으로 예측된다. 본 연구결과는 발전소 온배수열 활용사업에 대한 정부지원금의 효과성을 경제적 평가측면에서 분석한 점에서 의의를 가지며, 향후 시범적용 또는 Pilot 단계의 실제 적용사례를 기반으로 한 경제성 평가결과에 대한 필요성을 제기할 수 있는 근거가 된다.

  • Currently the forest area is 6,370,000 hectare (ha) which occupies 63.7% in Korea. The forest has good functions such as production of forest products, conservation of national land, prevention of disasters, etc. However constructing houses near the forest area make bad situation like illegal waste incineration by resident. So research subject is forest fire caused by waste incineration place including facility. And this study was conducted about statistical analysis and research analysis of the 100 waste incineration places including facilities at the country town. Statistical analysis shows that March is 27% which percentage is the highest number of forest fire in 10 years' average. The number of forest fire caused by waste incineration is 45 which is the third highest number in the fire statistic. The distance between waste incineration place including facility and forest area is 30m, 40m and 50m. That 40m (36%) is the most common distance from forest area. The types of waste incineration are ground (62%), the temporary facility made with oil drum can (35%) and other made with steel sheet, concrete, etc. The result of this study is that government and local government must conduct the improvement measure to reduce illegal incineration such as waste pickup area made with rain and wind proof type installed near residence, expenses for waste treatment, enlightenment and training, etc. Also considering their age and income are needed for realistic improvement.

  • The problem of outdated and surplus facility-items in existing Rural Living Environment Renewal Program(RLERP) makes this study focus on restricting the range of facility sorts for the purpose of coㅁins with the changing rural living environment. In the four aspects of plan establishment, project implementation, comprehensiveness and linkage between programs, this study made an analysis of the existing RLERP that has 4-stage hierarchy, namely, Gun(county), Myun(primary administrative district), village and project site level Firstly, Myun and upper level policy programs fulfill the comprehensiveness and planning aspects, but have defects in the implementation and linkage aspects. Secondly, the village level programs satisfies more or less the four condition, but give rise to the problems of equity between the project target village and the non-target, and of generalization of the planning method applying to a specific village. At last, project level programs, controlled by several ministries, have defects in comprehensiveness and linkage aspects, exposing the sectoralism of central government. Above all, the existing RLERP has so many facility items, which have led to inefficient investment till now. Therefore, it's necessary that the environmental facilities should be selected(simultaneously reduced ), referring to following 5 criteria. (1) Exception of facilities relating to agricultural production. (2) Confined to public facilities to be constructed by government support. (3) Common-use facilities located in small town and below level area. (4) Consideration of not only the present need but also the future need of rural residents. (5) Reflection of a regional difference of mountain, plane and suburban area. Just 13 kinds of living environmental facilities are finally selected as the result of the selecting work, which can be an new alternative for RLERP. Concludingly, the selected facility items should be integrated into a designated project site by the prepared plan in order to enhance the efficiency of RLERP, investment and also to satisfy the four analytic aspects mentioned above.

  • In this study, the function and purpose of the disposal cover, which is an engineering barrier installed to isolate the disposal vault of the near-surface disposal facility for radioactive waste from natural/man-made intrusion, and the design details of the demonstration facility for performance verification were described. The Demonstration facility was designed in a partially divided form to secure the efficiency of measurement while being the same as the actual size of the surface disposal facility to be built in the Intermediate & low-level radioactive waste disposal site of the Korea Radioactive Waste Agency (KORAD). The instruments used for measurement consist of a multi-point thermometer, FDR (Frequency Domain Reflectometry) sensor, inclinometer, acoustic sensor, flow meter, and meteorological observer. It is used as input data for the monitoring system. The 3D monitoring system was composed of 5 layers using the e-government standard framework, and was developed based on 4 components: screen, control module, service module, and DBIO(DataBase Input Output) module, and connected them to system operation. The monitoring system can provide real-time information on physical changes in the demonstration facility through the collection, analysis, storage, and visualization processes.

  • This paper is the result of simulation modeling concerning high-level radioactive waste repository(HLRWR) and people's mind for the facility. We describe a procedure of simulation modeling for resident's policy acceptance and perceived risk of HLRWR facility by using System Dynamics approach. To Complete some complicated works, we made the 20 pieces of stock-flow diagrams based on the causal loop diagram that is a blue print of whole variables and relations. The simulation outputs clearly show that cental government efforts to siting the HLRWR will be failed if nothing to give for the region's residents. On the contrary, a monetary incentive and a regional development program help to turn this gloomy situation into a desirable and acceptable condition dramatically. Government has to prepare the schemes considering the HLRWR acceptance and total supporting program including the cash and local development programs.

  • Since the HF release in 2012 in Korea, it became one of the most significant to evaluate consequence to the vicinity of industry facilities handling hazardous materials. BTX plant is selected to assess off-site risk to check whether the facility satisfies the Chemical Control Law by Korea Government. Accident scenarios were listed using process safety information. The scenarios having effect to the off-site were selected and assessed further according to guideline provided by Korea government. Worst case and alternative scenarios including other interested scenarios were evaluated using ALOHA. Each evaluated scenario was assessed further considering countermeasures. The results showed that the facility handling chloric acid is safe enough and needed no further protections at the moment.

  • Recently, biomass application for energy is getting more interests from many countries since biomass is widely available over the nation wide, whereas fossil fuels are produced in several limited regions. Recognizing the importance, government is promoting renewable energy use in Korea. The locational characteristics of the existing biomass potential directly can be used to decide scale of power plant for local agricultural facility. Although there are a few studies on feasible biomass potential in local areas, it is expected that both government and commercial sectors recognize the potential of biomass energy and the importance of reducing greenhouse gases. When planning biomass energy systems, biomass price is determined by the costs of collection, transportation, chipping, drying if required. In this paper investigates the economic and spatial characteristic of biomass location by land use map. However typical area of each categories in local region is not correct to agricultural census data. Therefore we concerned about how to calculate feasible biomass potential which it can be describing total amount of plant scale, and to match both of data. Even though its spatial distribution, in rural area in Korea, to expand biomass energy programs in the area, government serve to find areas of higher biomass production with suitable locations for plants to convert to bio-energy in order to increase the usage of renewable energy.
