This paper investigates the cost structure ot the Korea and Japan railroad industry with respect to density, scale and scope economies as well as productivity growth rate using a generalized trans)og multiproduct cost function model. The paper then assumes that the Korea and Japan railway companies pi·educe three outputs (incumbent railway passenger-kilometers. Shinkansen passenger-kilometers, ton-kilometers of freight) using four input factors (labor, fuel, maintenance, rolling stock and capital). The specified cost function includes foul other independent variables: track lengths to reflect network effects, two dummies to reflect nation and ownership effects, and time trend as a proxy for technical change. The simultaneous equation system consisting of a cost function and three input share equations is estimated with the Zellner's iterative seemingly unrelated regression. The unbalanced panel data used in the paper, a total of 154 observations. are collected from the annual records of the Korea National Railroad (KNR) for the yews $1977{\sim}2003$, Japan National Railways (JNR) for the years $1977{\sim}1984$. seven Japan Railways (JR's) for the years $1987{\sim}2003$. The findings show that the Korean and Japanese railways exhibit product-specific and overall economies of density but product-specific diseconomies of scale with respect to incumbent railway passenger-kilometers, Shinkansen-kilometers and ton-kilometers. However, the railways experience mild overall economies of scale which result from economies of scope associated with the joint production of incumbent railway/Shinkansen and feight, freight/incumbent railway and Shinkansen except Shinkansen/incumbent railway and freight. In addition, the economies of density and scale in the KNR, JR east, JR central, and JR west companies at the point of the years $1990{\sim}2003$ average is generally analogous to the above results at the point of sample average. There also appear to be economies of ssope associated with the joint Production of the incumbent railway and Shinkansen in JR central but diseconomies of scope in JR East and JR West. The findings also indicate that the productivity growth rate of the privately-owned JR's is larger than that of the government-owned KNR.

There have been various research in analyzing airport productivity such as measuring total factor productivity using the models of translog cost function. DEA(Data Envelopment Analysis) model is very useful in measuring productivity with linear programming when the output is not clearly identified and measured quantitatively in such complex facilities as airport. This study is to measure airport productivity using DEA approach for Northeast Asia. Seven international airports were analyzed including Incheon International Airport in Korea, Cheklapkok Airport in Hongkong, Narita Airport in Japan, and Changi Airport in Singapore. With the productivity measured, we can identify one of the important aspects of comparative advantage in hub competition in Asia.

Typical activity-based travel analysis has been focused on passenger travel using household survey data. The current research focuses on freight transport using one-day travel survey data. Passenger travel can be seen as the outcome of traveller's subjective decision-making, whereas freight transport is the outcome of shipper or transport company's optimized scheduling. The research conducts an activity-based analysis of freight-vehicle trip chains. In particular, the research focuses on the difference in travel pattern between shipper-oriented private vehicle and transport company-oriented business vehicle. The research analyzed the travel diary of freight vehicles collected as part of the third national logistic survey in 2005. The diary is freight driver's one-day travel record including the information of loading capacity, item transported, destination, arrival time, etc. The analysis results show the difference between private and business vehicles in the travel pattern regarding the sequences of destination, destination type and item transported and the multi-dimensional information of the three sequences.

현재 정부는 지금까지 관청 조직인 철도청에 의해 철도시설의 건설 및 유지관리 업무와 열차 수송 업무 등 운영부문을 일괄적으로 수행되어 오던 우리나라의 철도교통체계를 근본적으로 변화시키는 작업을 추진하고 있다. '철도구조개혁'이라 지칭되는 이러한 작업은 소위 말하는 상하분리 또는 수직적 분리의 원칙에 따라 철도청의 업무를 하부구조에 해당하는 기반시설(infrastructure) 부문과 철도차량을 운행하여 여객과 화물을 운송하는 운영부문으로 구분하여, 기반시설에 해당하는 부문은 기본적으로 사회간접자본의 개념에서 국가의 책임으로 하고 운영부문에 해당하는 부문은 타 교통수단의 운영주체 위상(예: 고속버스 회사, 항공회사 등)과 같은 민간 경영체제로 전환한 다는 것이 주 내용이다.(중략)

Auf die ganze Welt macht unbemannte $Flugger{\ddot{a}}te$(sog.Drohnen) in vielen Bereichen rasch Fortschritte und Anwendungen gezeigt. Nachdem ferngesteuerte Drohnen $urspr{\ddot{u}}nglich$ $prim{\ddot{a}}r$ $f{\ddot{u}}r$ $milit{\ddot{a}}rische$ Zwecke entwickelt wurden, $erh{\ddot{o}}cht$ sich derzeit ihre zivile Nutzung sowohl im Freizeit- als auch im Dienstleistungsbereich(Paketdrohnen, Drohnen-taxi) stetig. Mit der vermehrten Drohnennutzung steigen allerdings auch die damit verbundenen Risiken und Herausforderungen. In Zusammenhang damit stellt sich dann die Frage, ob $gegenw{\ddot{a}}rtige$ Vorschriften im Bereich von Luftrecht zurecht gekommen sind. Es sieht sich gerade der zwei Schwerpunkt $gegen{\ddot{u}}ber$. Erstens kann $Passagierebef{\ddot{o}}rderung$ mit unbemanntem Luftfahrzeug(mehr als 150kg) im $gegenw{\ddot{a}}ritigen$ Luftrecht keine Anwendung finden. Denn das kor. Luftsicherheitsgesetz und sein Durchsetzungsverordnung definieren die Terminologie von unbemannten Luftfahrzeugen und unbemannten $Flugger{\ddot{a}}te$ als "wenn eine Person nicht an Bord geht und ferngesteuert wird". Also soll Drohne nach dieser gesetzlichen Definition nur "ohne Person" geflogen werden. Das besagt ohne Piloten und ohne Passagiere. Zweitens ist unbemannte $Flugger{\ddot{a}}te$(weniger als 150kg) nicht auf Handelsgesetz anzuwenden, auf das ${\ddot{u}}ber$ Anspruchsgrundlage und Zurechnungsnorm des gewerblichen Luftverkehr geregelt ist. Der unbemannte Luftfahrzeuglieferdienst bringt nicht nur die Gefahr einer $Besch{\ddot{a}}digung$ des Frachtguts mit sich, sondern auch die Gefahr von $Bodensch{\ddot{a}}den$ durch Dritte. Gemäß ${\S}$ 896 des Handelsgesetzes ist aber die Anwendung von unbemannte $Flugger{\ddot{a}}te$(weniger als 150kg) $hierf{\ddot{u}}r$ begrenzt, weil unbemannt $Flugger{\ddot{a}}te$ $einschl{\ddot{a}}gig$ in Ultralight $Flugger{\ddot{a}}t$ ist, die im Handelsgesetz ausschließlich besteht. Technische Fortschritt und die dadurch $erm{\ddot{o}}glichten$ kommerziellen Anwendungen werden die Nachfrage nach unbemannter $Flugger{\ddot{a}}te$ wecken. Die Umsetzung der $bez{\ddot{u}}glichen$ Vorschriften sollte auch diese Entwicklung aktiv begleitet und $fr{\ddot{u}}hzeitig$ kommuniziert und erarbeitet werden, damit Hersteller und Nutzer $fr{\ddot{u}}hzeitig$ Planungssicherheit haben.

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.

최근 들어 공항운영에도 마케팅개념을 도입해야 한다고 주장하는 경우를 자주 볼 수 있다. 항공 운송산업 초기에서부터 1970년대까지 공항운영은 안전성확보에 초점이 맞추어져 있었다. 1980년대 이후 항공운송산업의 규제완화와 항공수요 급증에 의한 공항 혼잡화 문제가 대두되면서 공항 운영에도 효율성과 수익성을 강조하게 되었고 일반기업 경영에서 개발한 운영 기법을 공항운영에 도입하게 되었다. 이러한 추세는 당연히 공항운영에 마케팅 개념도입을 고려하게 된 것이다. 그러나 아직도 공항마케팅에 대한 체계적 고찰이 이루어진 적이 없어 본 연구는 공항 마케팅에 관한 일반적 고찰을 목적으로 수행하게 되었다. 본 연구는 공항운영에 있어서 마케팅 개념이 도입되게 된 배경과 공항 마케팅의 특성 등을 고찰해보고 공항운영에서 마케팅 개념을 어떻게 실현 할 수 있는지를 파악하는 것을 구체적 목적으로 했다. 우선은 공항운영에 있어서의 마케팅 개념 도입 배경을 살펴보고, 공항마케팅의 특성을 고찰한 후, 공항마케팅이 처하게되는 환경과 공항마케팅의 목표를 분석했다. 논의된 환경 하에서 마케팅 목표실현을 위해 어떠한 방법으로 마케팅 부서를 조직하고 어떤 업무를 수행하는지를 선진국 공항의 예를 들어 정리하고, 공항마케팅의 주요 대상인 항공사와 여객에 대한 공항의 마케팅 활동 방법을 분석함으로써 본 연구의 목적을 달성하도록 했다.
