  • Aviation safety requires systematic national attention and management because aircraft accident produce greater undesired social impact, economical damage, and declining national credibility compare to other transportation accident. Specially, Republic of Korea has highly increased risk of air accident as a major air transportation point having small aerospace, connecting pacific ocean and Asia, and explosively increased air traffic produced by economical growth, operating numerous military aircraft for the South and North Koreas' confrontational situation. Also, greatly increased domestic and oversea air travels by Koreans and foreigners as well as air freight based on heightened Korea's national power, launching new low cost carriers, and popularized leasure aviation have produced large amount of aviation needs in various fields. However, national aviation safety management system gratifying increased aviation needs and aircraft operations is seem to be slow in progress. This paper will show optimized measures utilizing private, governmental, and military resources to prevent aircraft accident under circumstances of limited budget and an favorable conditions, then will propose several action items.

  • Effective management of ULD (Unit Load Device) in Air Cargo Transportation is one of the Airline's main concerns. At present, the way of management of ULD which has the ID tag based on RFID is carried by cargo control staff with PDA. However, the activity of ULD management is limitted due to complexity of cargo terminal facilities. In this study, we offer the effective way of management of ULD by the DRONE equipped by LED-ID & RFID READER at the higher altitude in Air Cargo Terminal to recover the difficulty of identification due to complexity of terminal facilities. Further to the above, we suggest the operational effectiveness, limitation, and the direction of future research.

  • Air pollution in large cities is reduced through the environmental health policies, but due to increased population and automobile, some pollutants are still a problem. These air pollutants are known to cause asthma and respiratory diseases. According to an OECD report, the number of premature deaths will increase. Hazardous air pollutants should be managed through a systematic monitoring, risk assessment, and many studies are in progress. In order to manage hazardous air pollutants, transformation of policy for the protection of human health is required. management policy through the calculation of the excess number of deaths that occur from hazardous air pollutants for the public health is necessary. Korea has put a lot of efforts for air quality, but health risk assessment should be more considered.

  • Health benefits from implementing air quality control measures were assessed using the Environmental Benefits Mapping and Analysis Program (BenMAP). BenMAP developed by US EPA is a GIS-based software tool that estimates the health impacts and associated economic values connected with changes in ambient air pollution. Once a set of BenMAP-required data was collected, the health benefits from implementing Seoul Air Quality Management Plan (SAQMP), an official AQ improvement plan for Seoul Metropolitan Area, was assessed using BenMAP. The PM10 concentrations assuming the SAQMP implemented successfully were predicted with the MM5 (Mesoscale Meteorological model version 5)/CMAQ (Community Multiscale Air Quality) model. A PM 10 exposure related premature mortality function was adopted trom a well-known epidemiology study. Economic valuation functions driven from benefit transfer methods were utilized. Through the SAQMP, PM10 concentrations were estimated to be lowered by $15{\mu}g/m^3\;to\;75{\mu}g/m^3$ depending on air quality modeling grids. 5,569 premature deaths (95% CI $3,264{\sim}7,809$ deaths) could be avoided in the Seoul Metropolitan Area. The economic value of the deaths avoided was estimated to $13.2 billion $(95%\;CI\;$890\;million{\sim}$28.2\;billion)$ using the benefit transfer value. BenMAP could be a useful tool for developing effective air quality improvement policy, enabling the policy makers to anticipate the effects of regulatory changes on people's health and the economy.

  • Air Traffic Management aims to fulfill the requirement of the aviation demander by constructing the most effective and safety aviation systems for providing safety and cost-effective service. All concerned parties of aviation present the needs of improving Air Traffic Management system for solving the issue of the current system and the air traffic capacity in the 21st century, and introduce the significant improvements from the conventional technology and method for the past 40 years. Accordingly, ICAO promotes the development of innovative procedures and technologies to solve the problems and meet the demands. It is the concept of Performance based Navigation(PBN) based on Communication, Navigation, and Surveillance/Air Traffic Management(CNS/ATM). This study defines differences between RNAV and RNP RNAV as methods of air navigation based on the CNS/ATM, and needs and requirements of PBN as an emerging global standard. It also outlines basic elements supporting and implementing the PBN concept.

  • This study aims to deveop a methodology for measuring the level of service quality in the air transportation. To measure the level of service quality, the approach taken here deals with not only the facility factors but also qualitative factors such as comfort and convenience as the influencing elements for service quality. The contents of this study can be summarized as follows: (1) For the systematic developement and management of air service, service factors of the air transportation are classified by AHP(analytic hierarchy process). (2) In computing the weight of service factors, a pairwise comparison method in AHP is used. (3) This study will suggest a method of measuring the competitive level of air service, and a result of an empirical study appling the method developed.

  • An air traffic control organization will require knowledge management to keep competitive advantage. A traffic controllers are forced to share their tacit as well as explicit knowledge among their organization to get aircraft's safety and efficient operation. The purpose of this study is to examine which factors influence the air traffic controllers' intention of sharing knowledge for the case of Civil Aviation Safety Authority, Ministry of Construction and Transportation. An ANOVA analysis shows that a difference exists between ages in terms of open mindedness towards sharing knowledge, the search for new knowledge and the recognition of the importance of sharing knowledge.

  • In this study, a discrete-event simulation model is developed to estimate load factors and the corresponding revenues under different pricing and dispatching policies. The model has been employed to forecast the inbound and the outbound air cargo demands of the major Northeastern Chinese cities, and the simulation results were compared to the actual demands obtained from real-life airline operations. The statistical analysis confirms that the simulation model is able to provide accurate estimates for air cargo demands, and thus, the model may be employed to be a useful tool for air cargo demand management.
