  • 대기오염의 제어가 발전 단가에 미치는 영향을 분석하기 위하여 전산 모델이 개발 되었다. POGEN은 석탄 화력 발전소에 대해 대기오염 제어 비용을 가산한 균등화 발전 단가를 계산한다. 부 프로그램 Pollution은 대기 오염 제어 비용을 가산한 지배 방정식을 사용하여 총 자본 비용과 변동비용을 계산한다. 이 비용은 균등화 발전 단가를 계산하는 부 프로그램 GENeration의 추가 입력으로 사용된다. 탈황설비의 직접 비용에 대한 Pollution을 이용한 결과는 경험이 풍부한 선진국에서 발간된 비용 자료로써 검증하였다. 2001년의 전력 생산비용은 석탄화력발전소에 적용된 세 가지의 규제 시나리오에 의해 추정되었다. 입력 변수의 중요도와 미래 발전소에 대한 입력 변수에 포함된 불확실성 때문에 생기는 불확실도의 전파를 검토하기 위해 Latin Hypercube Sampling과 Multiple Least Squares 방법을 사용하여 민감도 분석과 불확실도 분석을 수행하였다. 가장 민감한 입력 변수는 원자력, 화력 공히 할인률이다. 배출가스제어 비용으로서 9-11 mills/kWh 정도가 추가되어야 한다. 이 비용은 전력 생산비용의 거의 20 퍼센트가 되고, 이에 해당하는 투자비는 1GW 용량의 석탄 화력발전소 초기 투자비용의 40%가 될 것이다. 원자력 발전에 대한 단가는 90퍼센트의 신뢰도로써 32.6-65.9, 석탄 화력에 대해서는 45.5-60.5 mills/kWh가 되며, 엄격한 규제 분위기 하에서는 원자력이 95%의 신뢰도로써 유리할 것이 전망된다.

  • The I.A.P.(Index of Atmospheric Purity) by the distribution of Bryophtes on the bark of various latifoliate tree trunks was investigated at four sites(Daeheung, Songkwang, Jeungsim, and Heunggook Temple) from April, 1991 to April, 1993. The IAP was in inverse proportion to the degree of air pollution. The I.A.P at four sites were estimated 78.2 at Daeheung temple, 61.0 at Songkwang temple, 28.3 at Jeungsim temple, and 10.3 at Heunggook temple, respectively. The distribution degree of Bryophytes in Heunggook temple progressed during the last ten years. It represents the bettrment of air quality. Bioassay by means of lichens seems to have great potential for better and less expensive ways of measuring pollution levels instead of the high cost of buying and maintaining air pollution monitoring equipment.

  • A new approach considering CO2 air pollution constraints in the long-term generation mix is proposed under uncertain circumstances. A characteristic feature of the presented approach in this paper is what effects give the air pollution constraints in long term best generation mix. Best generation mix problem is formulated by linear programming with fuel and construction cost minimization with load growth, reliability (reserve margin rate) and air pollutionconstraints. The proposed method accommodates the operation of pumped-storage generator. It was assumed in this study that the construction planning of the hydro power plants is given separately from the other generation plans. The effectiveness of the proposed approach is demonstrated by applying to the best generation mix problem of KEPCO-system, which contains nuclear, coal, LNG, oil and pumped-storage hydro plant multi-years.

  • This research suggest one-body type scrapped styrofoam crusher with sprayed air (or water), which at present separately composed of dust eliminator, air supplier and crusher. Air (or water) that supplied from compressor injected to rotating twin roller through axis hole, and sprayed out of fine hole on the surface. The crusher that manufactured with sprayed air (or water) can make high-quality primary styrofoam removed pollution and dust. In case of mixed sprayed air and water, clean degree of crushed styrofoam was higher than single sprayed air. This could be contributed to reduce environmental pollution, cost and space in standpoint of recycling scrapped styrofoam.

  • Kazakhstan's cities experience high concentrations levels of atmospheric particulate matter (PM), which is well-known for its highly detrimental effect on the human health. A further increase in PM concentrations in the future could lead to a higher air pollution-caused morbidity and mortality, causing an increase in healthcare expenditures by the government. However, to prevent elevated PM concentrations in the future, more stringent standards could be implemented by lowering current maximum allowable PM concentration limit to Organization for Economic Co-operation and Development (OECD)'s limits. Therefore, this study aims to find out what impact this change in environmental policy towards PM has on state economy in the long run. Future PM10 and PM2.5 concentrations were estimated using multiple linear regression based on gross regional product (GRP) and population growth parameters. Dose-response model was based on World Health Organization's approach for the identification of mortality, morbidity and healthcare costs due to air pollution. Analysis of concentrations revealed that only 6 out of 21 cities of Kazakhstan did not exceed the EU limit on PM10 concentration. Changing environmental standards resulted in the 71.7% decrease in mortality and 77% decrease in morbidity cases in all cities compared to the case without changes in environmental policy. Moreover, the cost of morbidity and mortality associated with air pollution decreased by $669 million in 2030 and $2183 million in 2050 in case of implementation of OECD standards. Thus, changing environmental regulations will be beneficial in terms of both of mortality reduction and state budget saving.

  • 본 연구에서는 톨게이트에서 하이패스 전용차선 제한속도변경에 따른 톨게이트에서의 교통흐름의 변화와 이에 따른 환경오염에 대한 영향을 비교분석하였다. 톨게이트 시뮬레이션을 위해서 인천톨게이트 자료를 이용하였으며, 다양한 하이패스 전용차선 제한속도에 근거하여 시뮬레이션을 시행하였다. 미시적 시뮬레이션 분석을 위하여 본 연구에서는 Paramics가 사용되었다. 시뮬레이션 실행결과, 현재보다 높은 하이패스 제한속도 (70Km/h)가 기존제한속도 (30Km/h)에 비하여 톨게이트에서 교통류의 흐름에 긍정적인 영향을 미치고 환경적으로도 긍정적인 영향을 미치는 것으로 나타났다.

  • A valuation of air pollution is critical for relevant policy-making for the public and research direction. This study conducted a willingness-to-pay (WTP) survey using contingent valuation method (CVM) in Seoul Korea. In detail, this study puts an emphasis on its temporal changes referred on two surveys conducted in 2014 and 2019. In reference to the previous studies in 2002, our survey indicated that the public awareness of air pollution and interests on its sources and solutions increased noticeably. Our survey showed that WTP increased significantly from 2588 to 4827 and 8240 Korean Won $month^{-1}$ in 2002, 2014, and 2019, respectively. Moreover, the percentage of respondents to pay the WTP also increased from 48% to 68% and 79% in 2002, 2014, and 2019, respectively. Our analysis based on the number of Google search on particulate matters (PMs) strongly suggests that such the noticeable increases of the public attention to air pollution is well accorded with the moment of the announcement of a standard for ultra-fine particles and the start of PM prediction in late 2013. But the Google search rate grew about 16.7 times in 2009 compared to 2014, which is much larger than the growth rate of interest and WTP between 2014 and 2019. Our results shed light on policy decision for the right person in the right place on the right time in the era of air pollution.
