  • The recent rise in SARS and bird flu infections around the world has raised the interest in studying the habits of air borne pathogens such as germs and viruses. In this study, simulations were carried out to predict the performance of UVGI air sterilizer at preventing airborne infections inside a car, based on the installation position and the removing effect of the UVGI air sterilizer. Simulation results showed that the UVGI air sterilizer was most effective when located at the rear side of the front seats. It was also showed that when the out-air mode and the UVGI air sterilizer were set to the highest capacity, the microbial safety levels were maintained in a car for 21 hours.

  • The main purpose of this study is to develop air transportation cultural index which is able to estimate the level of them. Generally Speaking, air transportation cultural, a compound word of 'air transportation' and 'culture', is a substantial entity consisting knowledge, art, morality, legality, cultivation, customs, and etc, which comes from aircraft operation sector, airport operation/management sector and user sector. They are classified in a primary scope, as aircraft operation sector relating to flight operation, airport operation/management sector and user sector. The research and analysis were taken approximately 4 months, from June 2004 to October 2004. To evaluate the index, the detailed item for three categories were chosen and quantified. The grades for each items were induced from calculation formula for air transportation cultural index by applying weight values. The final grade of Korea's air transportation cultural index recorded 63.19 points.

  • Meteorological factors and air pollutants are associated with respiratory diseases, and appropriate use of weather and air quality information is helpful in the management of patients with such diseases. This study was performed to investigate both the utilization of weather and air quality information by, and the needs of, patients with respiratory diseases. Questionnaires were administered to 112 patients with respiratory diseases, 60.7% of whom were female. The rates of bronchial asthma and chronic obstructive pulmonary disease among patients were 67.0% and 10.7%, respectively. The majority of subjects (90%) responded that prevention was important for respiratory disease management and indicated that they used weather and air quality information either every day or occasionally. However, respondents underestimated the importance of weather and air quality information for disease management and were unaware of some types of weather information. The subjects agreed that respiratory diseases were sensitive to weather and air quality. The most important weather-related factors were diurnal temperature range, minimum temperature, relative humidity, and wind, while those for air quality were particulate matter and Asian dust. Information was gleaned mainly from television programs in patients aged 60 years and older and from smartphone applications for those below 60 years of age. The subjects desired additional information on the management and prevention of respiratory diseases. This study identified problems regarding the utility of weather and air quality information currently available for patients with respiratory diseases, who indicated that they desired disease-related information, including information in the form of action plans, rather than simple health- and air quality-related information. This study highlights the necessity for notification services that can be used to easily obtain information, specifically regarding disease management.

  • Even a small amount of hazardous air pollutants could have a harmful influence upon human beings, animals and plants. Hazardous air pollutants have the properties of toxicity, canceration and organism accumulation. They include heavy metals, volatile organic compounds, polycyclic aromatic hydrocarbons, dioxin, etc. The Clean Air Conservation Act has defined specific hazardous air pollutants and designated 35 pollutants, distinguishing them from common air pollutants for special control. This study investigates the history of the controls of specific hazardous air pollutants with reference to some relevant laws and regulations in Korea. It investigates the regulations at the permission stage, such as the restrictions on installation of emission facilities, the permission and reporting of installation of emission facilities, and the regulations at the operation stage, such as maintaining permissible emission levels, installation of measuring devices, dues for emission, self-measurement and securing environmental engineers. The current regulatory management is not so satisfactory in regards to the serious effects of specific hazardous air pollutants upon the human body. An advanced new concept, like the maximum available control technology in US, the facilities management standards, which will soon take effect, will be able to lessen the emissions of fugitive hazardous air pollutants. In addition, this study discusses some possible stricter controls on the emission facilities of specific hazardous air pollutants and proposes some measures to maintain and supplement the current systems.

  • The unequivocal risk of climate change, the weakness of energy security, and the problem of air quality will be possibly accelerated by the same reason, the enhanced fossil fuel dependancy in the future. It is obvious that greenhouse gases and air pollutants are mainly emitted from same sources. Moreover, greenhouse gases and air pollutants have their adversed impacts on same socio-economical, and environmental sectors. With these regards, several but limited studies have emphasized on the importance of the integrated management of climate change and air quality problem. In this study, we address the current trend of energy consumption and the change of air quality condition. Also the related policies are checked out in order to reduce emissions of greenhouse gases and air pollutants in Korea. By surveying previous studies, it is shown that the cost of climate change actions can be reduced by air quality co-benefits and vis-a-versa. Also the integrated strategy for climate change and air quality is introduced in term of cost-effectiveness and co-benefit.

  • This paper intends to prevent dangerous goods shipments from compromising safety, and to minimize the risks to life and property inherent in air transport of dangerous goods. For this purpose, this paper reviews the changes of international standards for the international air transport of dangerous goods, and recommends the methods for improving the management system for the air transport of dangerous goods. As for the research methodology, this paper reviews the current regulations of the ICAO Technical Instructions for the Safe Transport of Dangerous Goods, IATA Dangerous Goods Regulations, and national regulations governing the air transport of dangerous goods in Korea. As the results of this paper, it is anticipated that the national regulations for shipping dangerous goods by air will be detailed, and compliance with the regulations will be enforced. In conclusion, ensuring the safe transport of dangerous goods by air is a shared responsibility of the government authorities, carriers and shippers.
