This paper proposes an optimal incentive scheme for environmental pollution and output control in oligopoly markets under asymmetric information situation where the regulator has no information about each firm's technology on output productions and pollution abatements. We compare two interesting optimal incentive schemes (one is static model previously proposed and the other is dynamic model suggested in this paper), analyze features of these schemes, and carefully discuss its relevances to other schemes.

Air pollution problems are serious and present significant challenges to the engineering research community. EPA's engineering research programs have shifted from a primary focus on $SO_2$ and NOx pollution control to more complex and more difficult problems such as indoor air quality, air toxics, and global climate change. EPA research engineers are working closely with other research organizations in both the private sector and other federal research organizations to identify, evaluate, and develop cost-effective engineering solutions. The APPCE works closely with the EPA regulatory and regional offices to ensure that the best engineering information is utilized to formulate and implement the Agency's environmental protection program.

When considering marine pollution control procedures there are three general areas which demand close attention. These are: $\bullet$ oily bilge water $\bullet$ refuse $\bullet$ sewage All of these applications can be handled constantly changing to address the complexity of the waste management issues. The basic marine pollution regulations are covered by the International Maritime Organizations MARPOL 73/78 convention, with the various annexes and revisions. Of particular importance for equipment to deal with oily-water, sewage and plastic wastes.

유조선은 보통 상선과는 다른 선체구조와 작업환경을 가지고 있다. 유조선에서 사고가 발생하면, 보통 상선에서는 선박과 화물에 제한되지만 유조선 사고에 따른 피해는 선박과 화물에 추가하여 유류유출에 따른 엄청난 제3자에 대한 배상책임을 져야한다. 따라서 유조선 운항에 따른 위험요소, 사전/사후손실통제, 해상 보험과 관련된 법규정을 이해하고, 기대하지 않은 사고가 발생할 때 피해를 최소화해야 할 것이다. 이러한 피해를 줄이기 위해서는 사전에 유류오염방지 시스템구축 및 유류오염 피해보상에 대한 준비를 해야만 한다. 이러한 준비에도 불구하고, 유조선 사고는 빈번히 발생하고 있다. 이에 본 논문에서는 유조선 운항에 따른 근본적이면서 전반적인 위험관리 방안에 대해 연구하였다.

In this paper, we study on a modified mesh generation method based on the pollution error estimate. This method is designed for the control of the pollution error in any patch of elements of interest. It is a well-known fact that the pollution error estimates are much more than the local one. Reliable a posteriori error estimation is possible by controlling the pollution error in the patch through proper design of the mesh outside the patch. This design is possible by equally distributing the pollution error indicators over the mesh outside the patch. The conventional feedback pollution-adaptive mesh generation algorithm needs many iterations. Therefore, the solution time is significant. But we use the remeshing scheme in the proposed method. We will also show that the pollution error reduces less than the local error.

Urban pollution has been a problem in China since ancient times. In modern times, pollution was aggravated by industrialization and urbanization and became closely related to people's lives. Shanghai was the industrial center and the most urbanized place of modern China. As a price, it needed to face extremely serious urban pollution, and the treatment of this problem involved all aspects of social life. Noise pollution let foreigners to interpret the Chinese people and the city of Shanghai from a cultural perspective, and let Chinese residents to understand Shanghai and the nation from a civilized perspective. Pollution regulation made Shanghai the first city in modern China to implement overall pollution control and levy environmental protection fees. It also enabled the Chinese to gradually fight for their rights in urban governance. Urban pollution also brought business opportunities; in the highly commercial city of Shanghai, it promoted the development of some industries. The experience of urban pollution and its treatment prompted the people of Shanghai to rethink and re-recognize modern civilization, and also promoted the formation of Shanghai urban community.

본 연구의 목적은 대표적 점오염원인 석탄화력발전소의 대기오염방지시설을 개선했을 때 최대 착지 농도 및 주변지역의 대기오염도 변화를 파악하는데 있다. 대기오염방지시설 개선 전 후의 대기질을 예측 비교하여 시설의 개선 효과가 어느 정도인지를 분석하였다. 대기질 예측에는 바람장의 변화를 Puff의 이동으로 나타낼 수 있고, 비정상 상태를 구현 할 수 있는 대기오염확산모델인 CALPUFF 모델을 이용하였다. 화력발전소의 주요 대기오염배출 물질인 아황산가스($SO_2$), 이산화질소($NO_2$), 먼지($PM_{10}$) 항목을 예측 항목으로 선정하였다. 연구결과 $SO_2$, $NO_2$ 항목은 대기오염방지시설 개선으로 인하여 최대 착지지점 및 주변지역의 대기질 오염도 감소에 상당히 효과가 있는 것으로 분석되었다. $PM_{10}$ 항목의 경우에는 최대 착지지점에서는 오염도 감소 효과가 높으나, 석탄 화력발전소 주변지역의 대기오염도 감소 효과는 다소 낮게 분석되었다.

Water quality of the Lake Youngrang in the Sokcho City is eutrophic. Jangcheon is the largest inflow source to the lake. Major pollutant sources are stormwater runoff from resort areas and various land uses in the Jangcheon watershed. A storm sewer on the southern end of the lake is also an important pollution source. In this study, water quality modelling for Lake Youngrang was carried out considering the rainfall-runoff pollution loads from the watershed. The rainfall-runoff curves and the rainfall-runoff pollutant load curves were derived from the rainfall-runoff survey data during the recent 4 years. The rainfall-runoff pollution loads and flow from the Jangcheon watershed and the storm sewer were estimated using the two kinds of curves, and they were used as the flow and the boundary data of the WASP model. With the measured water quality data of the year 2005 and 2006, WASP model was calibrated. Non-point pollution control measures such as wet pond and infiltration trench were considered as the alternative for water quality management of the lake. The predicted water quality were compared with those under the present condition, and the improvement effect of the lake water quality were analyzed.

Nine districts in Seoul were chosen randomly and a questionnaire containing 23 questions was distributed to survey the perception of noise pollution by the citizens. The results were primarily analyzed to understand the perception of Seoul citizen as a whole, and then analyzed according to 4 demographic variables -district area, age, gender and occupation -to see if there were any possible relation between nonnoise variables and noise annoyance. Actual noise level data measured by the city government were used to compare quantified noise level with the surveyed people's perception. It was found that people consider road traffic noise to be the naix source of noise pollution In Seoul and that most people have experienced annoyance in everyday life. Also it was verified that the responsibility for noise control should be on both city government and the individuals, but It was generally considered that very little effort Is actually put Into solong norse pollution from both groups. From the survey, It could be analyzed that domographic variables do affect people In the awareness of noise pollution, and that one's sensitifty and annoyance due to noise increase as one ages. From the study, It was concluded that noise pollution Is not considered currently as a hazardous problem to most Seoul citizens, however specific noise reduction policies, especially regarding road traffic noise, should be put Into practice In the near future.

This paper examines the dynamics of environmental policy development in Korea by reviewing some of the ways on how the policy windows have been opened. There are a lot of theoretical arguments about the major factors influencing policy development or changes. Many scholars have believed that severe pollution accidents or salient environmental episodes might have been the main motivation of environmental policy development. This line of argument seems valid, especially with the water pollution control policy in Korea. Water pollution control programs had rapidly expanded along with the series of water pollution accidents in the tap water sources from the late 1980s to mid-1990s. However, regarding other major env. issues, various other factors have played more important roles in the development of the relevant policies. In case of air pollution control policy international sport events such as, 1986 Asian Games, 1988 Summer Olympics, and 2002 World Cup Competition, have contributed for the development. The municipal solid waste management policy partly owed its development to the introduction of local autonomy system in the mid-1990s. Even the foreign currency crisis occurring in December 1997 helped the policy paradigm shift from rigid supply-oriented to soft demand-oriented approaches. After closely looking at the dynamics of environmental policy development in Korea, this paper tries to identify the logical background of the observed outcomes.
