The air quality management in regional viewpoint was investigated for the improvement of national air pollution with various standard air pollutants. The focal region in this research is north-eastern region in asia where the many developing industries are located in neighboring countries. The major concerns were the trends of air quality in recent years and the state of environmental technologies and policies of air quality in each countries. The regional air quality management for the improvement of air pollution and the effective programs were suggested for the effective air quality management.

Policy direction for the management of air quality in Korea has been on the reduction of the average concentrations of the criteria air pollutants such as sulfur dioxide and fine particles. However, recently, risk based management of air pollutants becomes an important issue. In this study, to develop an effective air quality management policy direction in Korea, (1) the fourth Multiple Air Toxics Exposure Study (MATES IV) carried out in the South Coast Air Quality Management District (SQAQMD) in the USA is reviewed and (2) the results are compared with in these in Seoul and (3) policy directions are suggested. It was found that (1) systematic integrated study comprising of measurement, modeling, emission inventory estimation, and risk assessment was essential to estimate the health risk of air pollutants reliably, (2) cancer risk of diesel particle was dominant over other air pollutants, and (3) health risk based emissions were different from amount based emissions. It was suggested that (1) reducing the exposure from hot spots might important to reduce health risk from air pollutants and (2) an integrated air quality management administration system is important for the efficient management of air pollution.

With the rapid development of China's industrialization and urbanization, air pollution has become a growing concern. The emergence of air pollution not only affects people's health, but also restricts the development of China's social economy. This paper puts forward specific measures for air pollution control by examining the causes of air pollution and by comparing air pollution status and management policies between Korea and China. Methods of control involve improving the urban environmental management mechanism, spreading awareness of urban environmental management and air pollution management laws and regulations system, strengthening clean energy utilization and urban environmental greening, increasing investment and management funds and more. Through these measures, urban environmental management in China can be accelerated and level of environmental management improved.

건설사업은 인간의 생활의 질을 높이고 편리한 인간생활을 위해서 필수불가결한 요소이지만 이러한 건설행위자체는 개발과정에서 환경오염에 커다란 영향을 미친다. 또한, 쾌적한 환경에 대한 욕구 증대로 사업수행시 대기관련민원의 증가로 인한 공사지연이 빈번히 발생하고 있어 건설사업에서의 대기환경관리 중요성이 크게 부각되고 있다. 이에 본 연구에서는 건설사업시 환경관리를 위한 관리지침개발을 위해 건설사업 추진시 발생하는 여러 가지 오염 중 대기오염에 대한 관계법령 및 규제사항 검토, 환경관리 주요검토항목 및 주요관리지침을 도출하는 과정을 통해 건설사업 단계별 행동관리지침을 개발하여 건설사업의 환경관리 체계를 구축하는 것을 목적으로 한다.

In this paper, we aim to propose cyber security considerations and countermeasures for infrastructure and services in the UAM(Urban Air Mobility) Air Traffic Management field, which is one of the key elements of the UAM market that has not yet bloomed. Air traffic management is an important factor for safe navigation and social acceptance of UAM. In order to realize air traffic management, infrastructure and services based on solid network connectivity must be established. And for industries where connectivity is the core component, it can become an infiltration route for cyber threats. Therefore, cyber security is essential for the infrastructure and services. In detail, we will look into the definition of the existing air traffic management field and the cyber threats. In addition, we intend to identify cyber security threat scenarios that may occur in the newly designed UAM air traffic management infrastructure. Moreover, in order to study the cyber security countermeasures of the UAM air traffic management infrastructure, there will be analysis of the UAM operation concept. As a result, countermeasures applicable to the infrastructure and service fields will be suggested by referring to the cyber security frameworks.

Problems of secondary pollution and hazardous pollutants have rapidly come to the front in our society during the past few years. More attention should be paid to monitoring and assessment in order to identify the nature of complicated problems, but our air-quality policy is hurriedly seeking for management strategies. A typical example is air quality management in the industrial estates such as those located in Yochon and Ulsan. Yochon Industrial Estate was designated as a special air-quality management area of volatile organic compounds(VOCs) in 1996. And VOCs in the air of Ulsan Industrial Estate has been specially controlled since 1997. In this paper, however, it is suggested that hazardous air pollutants(HAPs) rather than VOCs should have been managed in the industrial estates. History of studies on organic compounds in the air of the industrial estates is reviewed. A stepwise approach for air quality management in the industrial estates is recommended.

환경재해방지와 대기오염관리를 목적으로 GIS기반의 대기 오염관리시스템 즉 높은 시 공간적 해상도의 오염물질배출량 산정과 영향예측, 자료관리 및 분석 등이 가능한 지리정보시스템을 구성하였다. 사례연구는 다양한 오염원의 존재하여 대기오염물질 배출량 증가로 인하여 환경재해의 가능성이 상존하는 광양만지역을 선정하고, 대기오염관리시스템에 오염원의 속성 공간자료체계를 구축과 배출모형, 대기오염모델, 분석도구 등을 이용하여 배출량 산정과 영향예측, 분석 등을 수행하였다. 분석결과, 산정된 배출량이 대상지역 오염원의 위치와 오염물질의 배출특성, 공간분포와 일치하는 정확한 예측결과를 나타내었다. 또한, 대기 오염모델의 TSP 예측결과는 실측값과 상관계수가 0.75로서 다소 높은 상관도와 오염원 영향농도와 범위 등의 파악에서 명확한 분석기능이 제공되는 것으로 나타났다, 본 연구에서 개발된 대기 오염관리시스템은 신속한 공간 속성 자료체계(database)의 구축과 높은 시 공간적 해상도의 배출량 산정, 대기오염모델의 입력자료 생성, 영향예측, 다양한 결과분석 등이 가능하여 합리적인 대기오염관리의 분석도구로서 사용될 수 있을 것으로 사료된다.

Managing hazardous air pollutants (HAPs) becomes an important issue with the amendment of the Clean Air Conservation Act in 2012. In this study, to develop an effective air quality management policy direction against the HAPs in Korea, (1) the HAPs control policies in the USA, United Kingdom, Japan, and the South Coast Air Quality Management District (SQAQMD) are reviewed, (2) the state of the art of the HAPs management in Korea are studied, and (3) policy directions are suggested. It was found that each country has its own policy priority and management directions. It was also found that the current HAPs management status is far behind to the countries compared in HAPs identification, emission inventory, monitoring, modeling, and risk management. Further policy directions are suggested.
