I generalized and analyzed the Supreme Court's judgements sentenced form Cho Sun High Court of Jus-tice to the present. Morever I tried to establish the system of a theory for surface rights from the viewpoint of the conventional law and present the direction in law-making political side. 1. The legal surface rights from the viewpoint of the conventional law have not been admited by the usage. Therefore I studied in detail its history, examples of foreign law-making, recognition authority and application object.

High Altitude Platform network systems utilize Unmanned Aerial Vehicle as routers for ground node communication. For this purpose, geographical clustering of ground nodes must be required. In this paper, we assume mobile ground nodes over wide area and the clusters composed of ground nodes are identified. UAVs can be positioned at the point of centroid of clusters. The number of UAVs are derived from the area size and the number of ground nodes deployed in that area. From the simulation and application of clustering algorithms, we showed visual clustering results with dynamic variance of number of ground nodes.

최근 초고속 멀티 미디어 통신망을 경제적으로 구성할 수 있는 하나의 방안으로서 성층권 통신시스템에 대한 관심이 증가하고 있다. 성층권 통신 시스템이란 대류권(Troposphere, 지상 10-20 Km) 위에 존재하는 성층권(Stratosphere, 지상 20-50 Km)에 통신 탑재체를 싣고 있는 비행선을 체공시켜 각종 무선 통신 서비스를 제공하는 시스템이다. 본 논문에서는 실측 데이터를 이용한 채널 모델을 적용하여 성층권 통신 채널을 섀도우잉이 포함된 라이시안 채널로 모델링하였으며, 이러한 채널에서의 BPSK시스템의 성능을 분석하였다.

Through the 2014 Donbas conflict and the 2022 Ukraine-Russia war, we are experiencing that the command of the air is no longer only secured by the Air Force. Long-range surveillance reconnaissance and strikes carried out by the Air Force could be replaced by drones and missiles, and the enemy's aerial attacks could be controlled by air defense systems such as Panchir and portable anti-aircraft missiles, allowing ground forces to carry out maneuvers freely. In other words, it is much more advantageous for the air force and the navy to take control of the air through long-distance operations, and the ground forces should support them. Therefore, this study aims to consider the cost-effectiveness aspect of the delivery command of the air; it provides implications for quickly responding to enemy air attacks by developing the air defense weapon system, drones, missiles, precision-guided munitions, etc rather than focusing on expensive fighter jets.

In order to investigate the factors and processes affecting the vertical distributions of ozone, we analyzed the ozone profile data measured using ozonesonde from 1995 to 1997 at Pohang city, Korea. In the course of our study, we analyzed temporal and spatial distribution characteristics of ozone at four different heights: surface (100m), troposphere (10km), lower stratosphere (20km), and middle stratosphere (30km). Despite its proximity to a local, but major, industrial complex known as Pohang Iron and Steel Co. (POSCO), the concentrations of surface ozone in the study area were comparable to those typically observed from rural and/or unpolluted area. In addition, the findings of relative enhancement of ozone at this height, especially between spring and summer may be accounted for by the prevalence of photochemical reactions during that period of year. The temporal distribution patterns for both 10 and 20km heights were quite compatible despite large differences in their altitudes with such consistency as spring maxima and summer minima. Explanations for these phenomena may be sought by the mixed effects of various processes including: ozone transport across two heights, photochemical reaction, the formation of inversion layer, and so on. However, the temporal distribution pattern for the middle stratosphere (30km) was rather comparable to that of the surface. We also evaluated total ozone concentration of the study area using Brewer spectrophotometer. The total ozone concentration data were compared with those derived by combining the data representing stratospheric layers via Umkehr method. The results of correlation analysis showed that total ozone is negatively correlated with cloud cover but not with such parameter as UV-B. Based on our study, we conclude that areal characteristics of Pohang which represents a typical coastal area may be quite important in explaining the distribution patterns of ozone not only from surface but also from upper atmosphere.

In recent years, due to the continuous density and urbanization of space, the expansion of awareness of rights, the need for landscape conservation, and the development of construction technology, the conventional flat land use has been deviated from the conventional flat land use, and the transmission line, urban railway, parking lot, communal district, underground shopping mall, pipeline, etc. Although 3D spatial activities are carried out in the form of 3D space, there are considerable difficulties in administration to manage the 3D use of land due to the inadequacy of related regulations. In this background, for the administration that can manage Sectional Superficies, which is a representative case of 3D spatial use of parcels, which is a registered unit of land, first, the law on the establishment and management of spatial information, and cadastral re-examination from the legal and institutional aspects Standardization of 3D space registration through amendments to the Special Act, etc. and the formation of consensus among related departments. Second, in technical and administrative aspects, the registration of Sectional Superficies based on cadastral survey results, establishment of a platform for integrated management of location and attribute data, and registration method was found to be in need of improvement. As suggested in this study, by registering and managing Sectional Superficies, it is possible to manage various 3D land use of not only ground space or surface space but also underground space. It is expected to be able to register and manage lot-based 3D land use efficiently.

과학과 기술의 발달로 급격히 발전하는 무기체계와 전략전술은 현대전의 양상을 과거의 대량물량전과는 달리 최단기간에 최대의 전과를 거둘 수 있도록 "속전속결" 중심으로 변화되었다. 이러한 속전속결전의 생명은 신속한 제공권 장악과 그에 따른 입체 기동전에 의한 기동력 확보이다. 제공권 장악에 있어 전투기의 미비점을 보완해오던 헬기는 잇따른 첨단장비와 기술 개발로 지상전의 핵심전투력인 전차의 기능에까지 그 영역이 확대되는 추세에 있으며, 전차의 정체성에 대해 재고의 필요성을 요구하게 되었다. 과연 헬기는 전차를 대체할 수 있는가? 이 글은 헬기와 전차 기술개발의 현재와 미래를 살펴보고, 각각의 기능 및 운용을 면밀히 분석하여 그 발전개념의 타당성을 검토하였다.
