The protection of space asset has been new major cause of space militarization. For such purpose, it has been officially announced that a policy of deterring and denying any adversaries from accessing the outer space. Space militarization is to be conversed into a new concept of space weaponization. The USA has announced its policy of space weaponization, while China and Russia have not revealed their plan or policy. Latter States, however, have proposed a draft treaty limiting the deployment of warfare in the outer space. The terms of the Outer Space Treaty, reflecting three significant United Nations General Assembly resolutions from the 1960s, support the position that ground rules must be observed in the exploration and the use of outer space, particularly in the absence of specific space law rules. Yet the combination (and culmination) of these two approaches to the legal regulation of outer space-specific rules as and when agreed by the international community and the translation of principles developed for terrestrial regulation to outer space-still leaves much room for uncertainty and exploitation for military and strategic purposes. As space weaponization may contribute to deterring the use of weapon, it may be not against the UN Charter Article 2(4). If space weaponization might generate the space debris such that the outer space is no more available for exploration and use, it is against the proportionality principle and discrimination principle enshrined in the laws of the war. But, if the limitation upon the kind and use of space weaponization is agreed among the States, then the space weaponization may not be against the laws of the war, and be considered permissible within the rationale of limited war.

Despite growing international cooperation for maintenance of international peace and security, wars continue to occur due to conflicted state interests. Continuing conflicts has advanced development of various weapon systems such as global integrated intelligence, surveillance and reconnaissance. However, with a big increase in the number of civilian casualties caused by the weapon systems development, the international community has also advanced diplomatic efforts to minimize deaths of civilian and military personnel. Therefore, it is essential to observe the principle of discrimination between combatants and non-combatants when operating unmanned aerial vehicles (UAVs), better known as drones. Drones have become more capable of distinguishing combatants from non-combatants due to its high-tech prowess. In the operation of drones, any parties involved in combat or the war are responsible for mounting civilian casualties. In addition, it should comply with the principle of proportionality that calls for a balance between results of such action and expected military advantage anticipated from the attack. The rule of proportionality prohibits use of military force which may be expected to cause excessive civilian harm. Drones have been able to track and monitor targets for hours and select the accurate locations of the targets. The aim is to reduce civilian losses and damage to a minimum. Drones meet the standards of Article 51.4 of the Additional Protocol.

In the sixty year since the first launch of Sputnik 1, it has become impossible to consider economic, political, or scientific human life in the communication field without reference to outer space. But, there is a growing groundswell of public opinion aimed at preventing arms race in space. Therefore it is necessary to establish some institution or mechanism such a code of conduct, international law. But every nation has a different posture on the grounds of national interest, or different levels of space development, the conditions required for the successful negotiation of a comprehensive treaty are not yet ripe. It is hoped that by beginning with soft measures (TCBM, Code of Conduct) for which it is easier to secure voluntary participation it may be possible to build up to a comprehensive treaty. The participation of the Space powers (US, Russia, China) in a dialogue of mutual exchange and shared information would contribute to international peace and give a long term benefit to humankind. It is also necessary to promote partnership through regional and bilateral cooperation. We should guide and shape opinion so that more nations ratify and sign existing international legal covenants in order to contribute to the efficency of Space law. International law needs to enforce PAROS and Space Security.

While in the early stages of space activities only a few states engaged in the use of outer space, as is well known, commercial space activities have grown dramatically in recent years. Both states, state institutions, and international governmental organizations as well as many private enterprises are engaged in such commercial use of outer space by now. This development is not reflected in the present state of space law. The existing international instruments of space law were developed and finalized before this development and thus only provide very few and sometimes unfitting provisions for the commercial use of outer space and particularly the use by private enterprises. Law formulated in an era when the word "privatization" had not even been coined cannot contain potential problems caused by the increasing commercialization of outer space. For the promotion and further development of such commercial use of outer space it is necessary to clarify and establish the legal framework for such use, because participants will need this information for their future investments in this field. The purpose of this paper is to research and make an analysis of the contents and international regulation of international space commerce, which is rapidly proliferating and to review the process of improvement on national legislations relating to the commercialization of outer space in a few main space advanced countries to make the sustainable progress of commercial space activities project in international society. The legal implications of matters such as international commercial launch services, the liability aspects of such services, intellectual property rights, insurance, product liability insurance and materials processing could one day will be subject to regulated by international space law as well as domestic law. In fact, the question of commercialization is linked to the question of sharing benefits of space activities, and this currently is an agenda item in the Legal Subcommittee of UN COPUOS. Most of developed countries have enacted the national legislation for commercial space activities relating to the development of our space as follows : The National Aeronautic and Space Act of 1958 and the Commercial Space Act of 1998 in the United States, Outer Space Act of 1986 in England, Establishment Act of National Space Center of 1961 in France, Canadian Space Agency Act of 1990 in Canada, Space Basic Act of 2008 in Japan, and Law on Space Activity of 1993 in Russia. Becides there are currently three national legislations relating to space development and commercial space activities in Korea as follows : Aerospace Industry Development Promotion Act of 1987, Outer Space Development Promotion Act of 2005, Outer Space Damage Compensation Act of 2008. Commercial space great promise for the utilization and expansion of human outer space activities but aspring commercial actors must recognize that foreign policy, as well as obligations to the international community as a whole, ensure that commercial space activities will not operate in a legal and regulatory vacuum. As commercial space matures the law and accompanying regulation will most certainly evolve and choose to become participants in the inevitable evolution of law and regulation.

세계 어디에서나 에너지의 수요가 급속히 증가하고 있는 반면, 인류가 사용 가능한 에너지 자원은 그 한계가 보이고 있다. 더욱이지구 온난화 현상이 표면화되어 있는 현 시점에서 인류의 사회활동은 환경문제와 밀접하게 연관되어져서 생각해야 한다는 것이 지구라는 close system 에서는 명확하다. 한정된 에너지 자원을 유용하게 사용하여 인류 미래의 삶을 보다 윤택하게 유지하기 위하여서는 사용목적에 맞는 최적의 에너지 형태로 효율 좋게 변환하는 것은 무엇보다도 중요하다. 열전기술은 원래우주개발 및 군사관계에 우선적으로 사용된 기술로써, 냉전시대의 미국과 소련이 개발경쟁을 한 바 있다. 열을 전기로 바꾸는 열전발전과 전기를 열로 바꾸는 냉동 보온의 양면으로부터 우주 탐사기에 탑재된 발전기, 잠수함용 냉난방장치, 비상용 전원, 자동차용 전원 등 가지각색의 system 이 고안되었다. 냉전시대가 끝나고 우주 군사 관계의 기술이 외부로 확산되게 되었으나 열전분야에서는 변환효율이 크지 않다는 단점으로 인해 민생부분으로 즉각적으로 전이할 수없는 어려운 점이 내재해 있었다. 에너지 및 환경의 문제가 심각히 대두되고 있는 오늘날에 이르러서야재료 및 그 응용에 대한 연구가 다시 붐을 이루어 활발히 진행되고 있다. 본 발표에서는 열전소재의 효율을 높이기 위한 고차나노구조 제어기술 및 그것을 이용한 최근의 연구결과들을 소개한다.

After its experiment involving the exploding of a satellite in space in 2007, China proudly aired news on TV and ran articles in newspapers. However, the event was internationally criticized and drew widespread attention. Many countries denounced the explosion by pointing out that it could be part of the nation's plan to expand its military power to space or that it could pose a danger to the peaceful use of space. However, there is no talk of whether the experiment that produced a huge amount of space debris could have violated an international law, namely the Outer Space Treaty. Although space garbage has been said to be a serious problem, the amount is still on the increase. If we continue to launch new space launch vehicles into orbit at this rate, we will not be able to use it anytime soon like we do today. As the commercial use of space is likely to increase, the situation will certainly get worse. The international community is fully aware of the seriousness of the problem and working together to reduce the amount of space garbage. However, despite the fact that the United States and Soviet Union's ASAT(Anti-Satellite) programs have been implemented for a long time, there have been no complaints about them in terms of military expansion or breach of the Outer Space Treaty. Also, the recent Chinese test is largely viewed to be in accordance with international law. A lot of research has been undertaken with regard to the problem of space garbage. Now people's awareness of dangers being posed has been fully raised. Under the circumstances, the dismissing of China's satellite smashing, leaving a big mess in its wake, as nothing more than an experiment, is a red flag to, if not many, at least some people. By means of this thesis, I would like to review whether the Chinese test has violated an international space law. This thesis presents an overview of the issues surrounding the event and examines the possibility of violating the Outer Space Treaty, formally the Treaty on Principle Governing the Activities of States in the Exploration and Use of Outer Space, Including the Moon and Other Celestial Bodies. After the China test, the UN Scientific and Technical Subcommittee first adopted space debris mitigation guidelines, I'll introduce the content of the guidelines and discuss the characteristics of the guidelines and what can be done to address the issue.

Today, satellites are widely used in many fields like communication and image recoding. The image acquired by satellites contains variety information of wide region. Therefore, they are used for agriculture, resource exploitation and management, and military purpose. The satellite is required to acquire images effectively in a given time period. Because the period that satellites can acquire images is very restrictive. In this study, the modeling of processing time and attitude maneuvering for satellite image acquisition is performed. From this modeling, mission planning algorithm using heuristic evaluation function is suggested and performance of the proposed algorithm is verified by numerical simulation.

Nuclear Power Sources(NPS) have been used since 1961 for the purpose of generating energy for space objects and have since then been recognized as particularly suited essential to some space operations. In January 1978 a malfuctioning Soviet nuclear powered satellite, Cosmos 954, re-entered the earth's atmosphere and disintegrated, scattering radioactive debris over a wide area of the Canadian Northwest Territory. This incident provided some reasons to international legal scholars to make some principles to regulate using NPS in outer space. In 1992 General Assembly adopted "Principles Relevant to the Use of Nuclear Power Sources in Outer Space". These NPS Principles set out certain legal and regulatory requirements on the use of nuclear and radioactive power sources for non-propulsive purposes. Although these principles, called 'soft laws', are not legal norms, they have much enfluences on state practices such as 1983 DBS Principles(Principles Governing the Use by States of Artificial Earth Satellites for International Direct Television Broadcasting), 1986 RS Principles(Principles Relating to Remote Sensing of the Earth from Space) and 1996 Declaration on International Cooperation in the Exploration and Use of Outer Space for the Benefit and in the Interests of all States, Taking into Particular Account the Needs of Developing Countries. As far as 1963 Declaration of Legal Principles Governing the Activities of States in the Exploration and Use of Outer Space is concerned the main points such as free use of outer space, non-appropriation of celestial bodies, application of international law to outer space etc. have become customary international law binding all states. NPS Principles might have similar characters according to states' willingness to respect them.
