This Article examines a structure of two Conventions of Space Station, compares 1988 Convention and 1998 Convention, and tries to apply "model" to it. The structure of 1988 Convention shows us three phases: the Convention as a framework, the bilateral memorandum of understanding and the legislation by domestic process of United States. There were many advantageous provisions for United States. In 1998 Convention, however, those provisions are dampened and provisions become impartial, for example, the criminal jurisdiction, the right of intellectual property and the codes of conducts in Space Station. On the other hand, we sets the "model" up, that is "input of national benefits and ideas ${\Rightarrow}$ process of law-making ${\Rightarrow}$ output of common benefits, universal ideas and wastes." In the case of applying this "model" to 1988 and 1998 Conventions, we are convinced of enough possibility to understand and explain the legal system of Space Station by this "model." This result awakes us that study of legal system of Space Station according to the "model" influences the fundamental theory of International Law Study: the relation between international law and domestic law. This "model" has possibility to change the theory of relation between from "international law and domestic law" to "domestic law and domestic law through international legal system." In the end, we should reconsider on "policy-oriented jurisprudence" by professor McDougal to use his key words for explanation of concepts in the "model," because his theory contains important suggestions to the study of law-making process and legal system for outer space activities in the near future.

Theories of international organization have explained the creation, maintenance, and decline of international organization. However, their explanations on changes of international organization have been much more different one another. For example, the theory of hegemonic stability argues that international organization can be created and maintained only by a hegemonic state and will be declined if the hegemonic state decline. On the other hand, the functional approach believes that the positive functions and effects that international organization provides motivate states to create and maintain the organization, while the game-theoretical approach explains international organization based on cost-benefit calculation of rational states. Thus, the empirical evaluation of the arguments of the theories of international organization and defining the major factors that determine international organization are necessary not only for the development of theories of international organization but also for making desirable policies toward international organization. For the purpose, this paper compares and contrasts the three major theories of international organization and applies the approaches to the case of the International Civil Aviation Organization (ICAO) to test their arguments. Since the ICAO has been rarely examined by the theories of international organization, the case study could be desirable case to evaluate theories of international organization. In this sense, this paper attempts to define the major factors that determine the creation, maintenance, and decline of the ICAO. In particular, since the Korean government has changed its policy for air transport security system recently, it will investigate the role of ICAO on the policy change to define the limits and strength of ICAO. In conclusion, this paper will assess the relative explanatory power of each approach based on the analysis of the creation and changes of ICAO

본 연구에서는 항공운송산업의 발전을 위하여 항공기 운항의 기반이 되는 국내 공역관리의 실태와 문제점을 검토하고, 이의 개선방안을 도출하고져 하였다. 한국은 세계10위의 국제적 민간항공국임에도 불구하고 경쟁력의 원천인 국내여건이 매우 취약한 실정이다. 국내 공역은 약 40만$km^2$인 대구비행정보구역내에 14개소의 접근관제구역과 16개의 항공로가 있고, 민간항공의 비행을 금지하거니 제한하는 71개소의 통제공역과 47개소의 주의공역이 설정되어 있다. 이와 같이 국내 공역은 매우 협소하고 복잡하며, 국가안보의 특수 상황으로 인하여 공역운영의 효율성이 떨어지며, 항공운항의 비경제성과 비행안전요인이 상존하고 있다. 이를 개선하기 위해서는 국가공역관리체제가 실질적이며 체계적으로 확립되어야 하며, 총체적인 국가이익의 극대화를 위하여 안보목적의 군 관할 공역과 민간항공이 활용 가능한 공역의 활당이 최적화 될 수 있도록 공역구조가 재편되어야 한다. 또한 운영상 효율성을 제고하기 위하여 접근관제구역의 광역화, 항공로체제 개선, 공역설계기준의 제정, 수도권 공역 부족의 해소와 미래항행시스댐 운영에 대한 대비가 필요하다.

The purpose of this study is provide better suggestions to utilize the small aircraft by examining current situations of those airports. Then, the results of this study should help explain about the Availability of the airports for small aircraft in view of airplane exhibition, air-sports activity fields for aviation sports population, aviation theme park, and aviation-related education facility. This study examines current situations of the small airports for small aircraft which have been limited in their utility and compares the airports at the same level abroad. By examining these airports, this paper can make suggestions for the Availability of the small airports. Significance of the study lies in providing businessmen planning to invest the small airports and owners of airports with profitable consequences. At the macro level, it is expected to have a more effective development of land and an increase of aviation market value.
