Demand for air transportation in Korea keeps increasing, and the number of airport operations also grows as a result. The major two airports in Korea, Incheon International Airport and Gimpo International Airport, share the metropolitan airspace, which is crowd with air traffic. As air traffic increases in the metropolitan airspace, the demand for the airport operations would outnumber the capacities of these airports. However, there is a room to efficiently manage the shortage of the airport capacity due to the different distributions of operations in these airports. This study presents a dynamic slot allocation that allows exchanging slots according to the traffic demand. The dynamic allocation mitigates the airports' capacity problem but the airspace capacity itself should be increased in order to tackle the problem fundamentally.

Advanced countries in the aviation industry, especially the United States and European Union, develop and commercialize their own SBD system integrated with IT convergence technology, dominating the international market. Nevertheless, most of SBD technologies in domestic airports rely on other countries. It is imperative that internal airport operators introduce the Self Bag Drop system and produce, apply, and manage the most optimized SBD system for airports and airlines. Upon analyzing the tendency and operation of the SBD system utilized in leading international airports, this is conducted to address the possibility of the future implementation in domestic airports.

The term "Privatization" has a different meaning in different contexts and cultures. In this paper, the term "Privatization" in the context of airports is defined as the movement of an entity from the government sector to the private sector. This is the definition that is commonly employed in the U.S. Airport revenue can he divided into two sub-categories of aeronautical revenue and non-aeronautical revenue. At many of the major international airports, however, non-aeronautical revenue has been growing faster than the aeronautical revenue, contributing an increasingly larger share of the total revenue. And the best way to enhance simultaneously the airport operations. With the remarkable growth in the air traffic volume of pssengers and cargo. more and more mega-international airports have been built or are under construction. As the air transport demand is expected to increase at an even greater rate in the 21st century, new types of airports which will be free of current major problems. such as airport congestion and flight delays are badly needed.

Recently, Intense competition is expected to bring about continuous change with the rapid global aviation industry. In particular, domestic passenger demand has been steadily increasing over the past five years, with domestic and international shipments growing at a CAGR of 8.4% and 10.0%, respectively. In addition to the economic value of the airport, social interest due to greenhouse gas emissions is also rising. In this study, we analyzed the efficiency of airport operation by using DEA model(Directional Technology Distance Function) considering undesirable output for 14 airports in Korea. As a result of analysis, all airports except Gimhae, Yangyang, Cheongju and Yeosu were analyzed as efficient airports. However, only Gimpo, Gimhae, Jeju, Muan, Daegu and Gwangju were analyzed as efficient airports considering the undesirable output.

지속적인 고속도로망 확충과 고속철도 개통 등에 따라fr개선 항공수요가 계속 감소하고 있다. 이러한 상황에서 각 공항과 지방자치단체에서는 지방공항을 살리기 위한 대책 마련에 심혈을 기울이고 있다. 이런 측면에서 본 연구는 고속철도의 등장으로 인한 대구국제공항의 현황을 분석하구 공항의 활성화를 위한 방안을 도출하고 대구공항개발에 대한 장 중단기간의 역할에 대한 로드맵을 제시하여 대구국제공항의 활성화를 통한 경쟁력을 확보할 수 있는 실질적인 이행방안을 제시하였다. 이런 관점에서, 대구시에 대구국제공항의 활성화를 위한 전담기구를 조직하여 일관적인 수요진작을 위한 지역 여행사지원, 대구국제공항을 주요항공 기지로 사용할 항공사의 지원, 일본의 지방도시에서 새롭게 개장하고 있는 공항에 대한 우선적 노선 개설, 중화권으로의 노선개설 및 확대 등을 적극적으로 추진할 것을 제안하였다. 건설교통부 차원에서는 인천국제공항의 허브화 지원만을 주요공항정책의 수단으로 삼고 있으나, 인천국제공항은 국가를 대표하는 공항으로 하되 수요의 흡수는 광역 수도권으로 하고, 향후 서해안권과 영남권의 거점 공항을 육성 할 필요가 있다. 국내 지방공항의 항공수요는지역인근의 자체 기종점 수요를 기반으로 하고 있어서 다거점 (1강 2중과 제주)으로 육성 할 필요가 있다는 견해를 제시하였다.

본 연구는 공항에서 활용되는 새로운 지표를 제시하고자 시작되었다. 일반적으로 공항에서는 여객과 화물을 처리하게 되며, 공항은 이를 통해 수익을 창출하게 되는 것이다. 하지만 공항들 모두가 여객과 화물처리실적이 동일한 분포를 보일 수는 없는 것이다. 여러 공항들을 상호비교 분석할 경우, 통일된 공항처리량 지표가 적용되어야만 공정한 결과를 기대할 수 있는 것이다. 현재 사용되고 있는 여객과 화물을 하나로 통합하여 적용하는 지표로는 '공항처리량단위(Work Load Unit)'가 있으며, 이는 여객 1명의 가치가 화물 100Kg의 화물량과 동등하다는 가정을 한 것이다. 기존의 WLU는 타당한 근거나 분석을 통해 설정되었다기보다는 공항에서 수행된 업무부하 정도에 관한 경험들을 바탕으로 설정된 것이므로 논란의 여지가 많다. 이와 같은 한계를 극복하고 새로운 지표를 제시하는 것이 본 연구의 목적이다. 여러 가지 접근방법을 적용할 수 있겠으나, 본 연구에서는 화물과 여객이 공항수익에 기여하는 상대적 가치가 어떻게 되는지를 비교하는 방법을 적용하였다. 화물가치와 여객가치를 분석하기 위해서 공항수익을 크게 항공기 운항관련 수익, 여객처리 관련 수익, 상업수익 등으로 구분하였다. 상대가치 분석을 위해 아시아 14개 공항, 유럽 18개 공항, 북미 지역 18개 공항 등 총 50개 공항이 선정되었다. 최종분석 결과에 따르면, 여객 1명의 수익기여를 기준으로 할 때 화물 280Kg과 동등하다는 결론을 도출하였다. 이는 기존에 적용되던 여객 1명당 화물의 가치를 100Kg으로 설정한 것보다 높은 수치를 보였다.

Purpose: The performance of global major airports is evaluated and several research questions are examined relative to the measures characterizing airport performance. Methods: The two-stage internal structure of airport performance is considered by decomposing it into physical operations and revenue generation. In the physical operations stage, operating costs, number of runways, terminal area and number of employees are used as inputs, while passenger throughput, cargo throughput and aircraft movements are taken as outputs. Subsequently, in the revenue generation stage, the outputs from the preceding stage are taken as inputs, while revenue is used as output. Results: Based upon this two-stage modeling of airport performance, a multiplicative two-stage network data envelopment analysis model is employed to calculate the overall and stage efficiencies of 59 airports using the recent data in the 2014 Airport Benchmarking Report published by the Air Transport Research Society. Several internal and external factors are also considered such as airport size, airport geographical location, proportion of international passengers, ownership (listed or not) and management style, and statistical analysis is performed to examine their impacts on airport performance. Conclusion: It is shown that the airports exhibit statistically significant difference across regions, and also some statistically significant factors affecting airport performance are identified.

Monthly variations of radiative forcing (RF) and mean temperature changes by greenhouse gases emitted from commercial aircraft were estimated based on the simplified expression at four international airports (Incheon, Gimpo, Jeju, and Gimhae Airports) during the years of 2009~2010. The highest RF and mean temperature change in the study area occurred at Incheon Airport, whereas the lowest RF and mean temperature change at Gimhae Airport. During 2009~2010, the mean RF and mean temperature change estimated from aircraft $CO_2$ emissions at Incheon Airport were approximately 30.0 $mW/m^2$ and $0.022^{\circ}K$, respectively. The mean RF and mean temperature changes caused by other greenhouse gas $N_2O$ was significantly small (<<0.1 $mW/m^2$ and << $1{\times}10^{-3}^{\circ}K$). Meanwhile, $CH_4$ emissions caused negative mean RF ($-4.45{\times}10^{-3}mW/m^2$ at Incheon Airport) and the decrease of mean temperature ($-3.83{\times}10^{-6}^{\circ}K$) due to consumption of atmospheric $CH_4$ in the aircraft engine.

This study is to explore the airline network patterns of Incheon and Narita International Airports using passenger flight departure and arrival data of the two airports. The so-called Origin-Destination data is collected from the airports' websites and some of the important data items are flight number, city of origin, destination city, departure/arrival time, number of flights, and delay time. A snowflake schema dimensional model is proposed and implemented. Tableau Public, a well-known visual analytic tool, is used to connect the dimensional model and played an important role in navigating the data space to find interesting and visual patterns among corresponding airports and airlines. For the efficiency of analyzing this spacious data mart, data visualization method was used. Four types of visualization method proposed by Yau was used; visualizing patterns over time, visualizing proportions, visualizing relationships, and visualizing spatial relationships. The strength of connectivity of each flight segments is calculated to evaluate the degree of globalization of Seoul and Tokyo. We anticipate that various patterns and new findings produced by the data mart would provide airline managers, airport authorities, and policy makers in the field of travel and transportation with insightful information.

It is anticipated that Gadeok New Airport will be constructed, and the entity responsible for its operation will be a new airport authority, not the existing airport corporation, as the Ministry of Land, Infrastructure and Transport has announced its plan to establish the Gadeok New Airport Construction Authority. Based on the precedents of existing airport corporations, it is expected that the future authority will undergo organizational changes to become an airport corporation. This study seeks to establish criteria for selecting overseas airports for benchmarking when researching the entity that will operate the newly established Gadeok New Airport authority. To provide a specific basis for selecting overseas airports for the future operation of Gadeok Airport, the Delphi survey method will be used to derive criteria. Currently, when examining the participation of local governments in regional airports, Gimhae International Airport is operated solely by the Korea Airports Corporation, receiving criticism for the lack of participation by the local government, such as Busan City, in decision-making related to airport operation and local reinvestment. Therefore, it is deemed necessary to provide early direction for improvement in this regard.
