  • The immigration procedure at airports is vital to making passenger and cargo transport faster. The rapid procedure of immigration could be an important determining factor when passengers select an air transport company, one that should have high satisfactory in terms of their service level and efficiency. Therefore, the advanced airport makes it easy for customers and their cargo to proceed. The coordination between authorities related to the Korean international airport is not satisfactory for customers. This paper analyzes the factors necessary to enhance the airport immigration procedure with the movement of aircrafts, passengers, cargo, and post, using the CK(Cook and Kress) model of DEA(Data Envelopment Analysis). From this study, the author found that research and development will be needed to improve the immigration procedure, especially on facilities and their operating systems. There are needed, also, performance indicators and a continuous monitoring system.

  • Incheon International Airport (IIAC) has been named "best airport worldwide" according to the AETRA Passenger survey Program that was jointly administered by Airports Council International (ACI) and the International Air Transport Association (IATA) in 2005. This paper identifies eight dimensions underlying the overall service qualify in passenger terminals. These eight elements were found from literature reviews through relevant documents. The research explains the linkage between the overall satisfaction with IIAC and five services that influence that satisfaction. The five services are the following: service quality of passenger terminals, commercial facility services, easy access by transportation, service quality of the airlines, and contributions to the community by IIAC. The data envelopment analysis (DEA) designed by Cook and Kress (CK Model) was used to maximize the efficiency of commercial facility services, easy access by transportation, service qualify of the airlines, and contributions to the community by IIAC because the model best provided practical plans for a more competitive airport. This paper has three significant results. First, it includes research of passenger terminal-oriented service quality. Second, the author researches service qualify focusing on a three-cornered relation among passengers, airline employees, and IIAC. Third, the paper contains research of service quality focusing on IIAC's employees.

  • The demand for specialized human resources capable of bringing about highly advanced logistics systems and the integration of logistics centers situated in local hubs, has been on the rise. Logistics industry requires more of a systematic mind set, endless innovation, and the navigation of uncharted waters than the logistics industry. This study lays out the reasons for the importance of developing human resources in the logistics industry, and then carries out an evaluation of the current state of human resources development in that particular field in Korea. This study found that there is not only a shortage in terms of the courses needed to develop the skills required to carry out the core activities associated with the logistics sector, but also that students' ability to speak English and Chinese, which are ubiquitous in the international logistics industry, was also wanting. There is a need for the study of logistics at the university level to be based on practical applications rather than theoretical ones.

  • To develop a crisis management for aviation safety, this study has defined crisis management includes risk management which is eliminates or lowers risks prior to accidents and emergency response after the accidents. This study takes a look at different kinds of crisis managements, risk managements and statistical methods of other nations and fields in order to develop a risk management model. Through surveys which have 102 risk factors that include air traffic control, maintenance and airport sectors, the weight of each risk factor was calculated and the probability was divided to develop a model for risk management. The risk management model of this study is conducted using four steps (risk management plan, risk factor identification, weight and probability analysis, decision making) and 4 standards of weight along with 5 standards of probability This study takes a look at Predictions through a quantitative method using a risk index for the risk management model An effective risk management model should have a wide and continuous collection of data and adopt various methods using this model. The crisis management could not be very effective only using a pre-active risk management. So it should also be conducted by using a pro-active response system to protect additional damage and to prevent accidents of the same nature. From the results, the most important points were the establishment of command and control accountabilities, and cooperation of related organizations.

  • This paper analyzes the differences in the service quality priorities of air cargo service providers and customers. After having identified what constitutes the decisive factors with regards to air cargo service quslity, research was carried out to evaluate the differences in the service quality priorities of air cargo service providers and customers. Moreover, this paper analyzes these differences by separating air cargo service providers into Korean and international air cargo service providers. In order to attain the objectives of this research, the air cargo service sectors were divided into three general categories: supply capability(H/W), service accountability, and competitiveness of service fees and management capability(S/W). The researchers then placed 6 different criteria into each service category, for a total of 18. The evaluation of the service quality priorities of air cargo service providers and customers revealed very little difference between these two groups. With regards to the service criteria found in each service category, our research found marked differences between the service quality priorities of providers and customers in only three of the 18 criteria. However, we found marked differences in service quality priorities in 7 of the 18 criteria when the air cargo service providers were divided into Korean and international air cargo providers. While domestic air cargo service providers evaluated management's capability to handle cargo accidents and incidents as the most important priority, international air cargo service providers placed the highest priority on the cargo rate system. The results of this research imply that in order to properly evaluate the differences between the service quality priorities of air cargo service providers and customers, the air cargo service providers itself should be separated between the Korean air cargo service providers and the foreign providers because of their respective inherent perception on service quality.
