The emergence of global internet access from the low Earth orbit (LEO) comes with cybersecurity vulnerabilities. Under international space law regimes, the concept of cybersecurity in outer space remains ambiguous. Furthermore, cyberattacks affecting the era’s thoroughly segregated computer space systems were unimagined. Cyber borders are not the same as physical borders. Cyberspace does not admit the demarcation of territorial sovereignty, as it is not based on physical location, and assigning territorial sovereignty to cyberspace is time-consuming. This research proposes the concept of a multi-stakeholder international legal regime for space cybersecurity, as establishing cybersecurity standards and risk management mechanisms necessitates technical measures and a regulatory framework. International cooperation is the only way to provide a fully coordinated approach to cyberspace protection which is consistent with the fundamental premise of international cooperation and collaboration in space.

The sustainable development of outer space demands the protection of intellectual property in outer space. However, it worth noting that the intellectual property international treaties have not explicitly regulated in their provisions the issue of intellectual property protection in outer space, neither the provisions of the five outer space treaties explicitly address the legal issue. One suspicious rationale resulting in this legal status is the theoretical territoriality paradox between the legal regimes of outer space and intellectual property. This article aims to unveil the theoretical territoriality paradox by comparing the two legal regimes of outer space and intellectual property. It then moves to argue that the paradox is proved to be a theoretical problem since the legal value of Article VIII of the Outer Space Treaty elaborately reconcile the theoretical paradox and practically provides a self-contained mechanism that would permit guaranteed levels of intellectual property rights protection in outer space.

Since the existing international legal regime governing space weapons is inadequate, the international community is worried about the weaponization of outer space. This paper introduces the efforts and contributions in this regard made by the UN General Assembly, the Conference on Disarmament, the UN Committee for Peaceful Uses of Outer Space and the UN Institute for Disarmament Research. It then analyzes several different approaches to solving the problem of weaponization of outer space, i.e. amendment of Article IV of the Outer Space Treaty, conclusion of a multilateral treaty on comprehensive prohibition of space weapons, and transparency and confidence-building measures in outer space activities. It concludes that a multilateral treaty on the prevention of weaponization of outer space with appropriate verification mechanism will be a final solution. At the present stage, a combination of various CBMs can also serve the purpose to prevent space weapons.

According to the historical documents and paintings in many civilizations, rocks that fell from the sky fascinated humans as the message from the God or supernaturals. Scientific progress allows humans to recognize these exciting extraterrestrial objects as meteorites. Meteorites contain a wealth of pivotal information regarding formation of the early Solar System. Meteorites also provide broader scientific insights on, for example, the origin of life, interplanetary transfer of life forms, massive depletion of biosphere on Earth, and evolution of lithosphere on Earth-like planetary bodies.

본 연구는 초고층 건축물 외부공간의 식물 피복 상태가 온도변화에 미치는 영향을 파악하고자 서울시에 위치한 초고층 건축물 12개소를 대상으로 연구를 수행하였다. 초고층 건축물 외부공간의 토지 피복 유형별 온도 차이 분석을 위해 6개 유형(외곽도로, 포장지, 관목/초지, 단층교목식재지, 다층식재지, 수경시설)으로 건축물외부공간의 피복유형을 구분하였으며 토지이용유형별 대표지점에서 온도를 실측하였다. 건축물 12개소의 주변 환경차이를 고려하기 위해 외곽도로의 중앙부에 대조구를 선정하여 온도를 측정한 후 일원배치 분산분석을 토대로 유사한 온도경향을 보이는 대상지를 4개 그룹으로 분류하였다. 분류된 그룹의 토지 피복 유형과 외부 공간 온도와의 일원배치 분산분석결과, 주로 단층교목식재지, 수경시설, 다층식재지는 저온역에 속하였으며, 관목/초지, 포장지, 외곽도로는 고온역에 속하였다. 저온역과 고온역의 온도차이는 약 1.06~6.17℃의 차이를 보였다. 그러나 조성된 식재지와 수경시설 면적의 협소, 건축물로 인한 일사도달량의 저감과 반사량의 증가 등으로 초고층 건축물 외부공간 온도에 미치는 영향이 다양하게 나타났다. 이에 각 공간에 필요한 녹지량과 수공간의 면적을 조성 전 미리 산출하여, 효과를 발휘할 수 있는 최소한의 면적과 녹지량을 확보할 필요성이 있었다.
