This study focused on the fact that changes of policies have influence on housing culture of Korea and analyzed changes in apartment houses planning since the deregulation of the price ceiling through newspaper advertisement. The research compared and analyzed advertisements of apartment houses sales appeared in the 'Gwangju Il-Bo' daily newspaper from 1990 to 2003 by planning factors. : The results are as follows. Reliability and economy were important factors in deciding apartment before the deregulation of the price ceiling policy, but as apartment houses were merchandised after the deregulation of the price ceiling policy, brand of enterprise and image of apartment houses were highlighted more. In the environment of apartment complex, the concerns of location after the deregulation of the price ceiling policy were more increased than before its policy and it means emphasis on living environment for better life. The apartment housing unit and building showed change of the apartment housing unit plan considering residents, high quality of interior design and high-tech and differentiation of equipment since the deregulation of the price ceiling policy. The ground space has been parked or afforested and the underground space is used for parking lot as a part of environment-friendly in the apartment complex planning. The deregulation of the price ceiling policy made brand, image, high-grade and differentiation, and got many changes in the planning side of the apartment sales advertisement.

Historically, college campuses have played a role of a city, and the development pattern of various forms and functions of cities was found in the growth stages of campuses as well. In this way, campuses developed in close relationships with our lives and such a characteristic can be confirmed in a number of cases in and out of the country. The strategic concept of such expansion is shown in the strategic classification through a master plan. This research examines concepts of major universities in the metropolitan area of Korea for promoting campus expansion and proposes implications through them. The results drawn from the research are as follows. Firstly, various developmental directions should be sought in aspects of planning, programming and economics for campus expansion with the complex application of such factors. Secondly, the multi-campus strategy of past localization era is changing into the concept of forming a global campus materializing itself as the planning strategy of internal campus. Thirdly, the physical barrier is being dissolved as a way to promote the relationship with local communities, and particularly, the management strategy of constructing new buildings in connection with local communities is the leading measure of materialization. Lastly, the development of underground space is actively carried out due to the limitation of ground physical space through which a role of establishing new campus order along with securing space is pursued.

각국의 무인기 카테고리 분류 기준에는 차이가 있으나, 대부분의 국가에서는 중량을 기준으로 25 kg(55 lb) 이하를 소형무인기로 분류하고 있다. 소형무인기는 주로 군사용, 공공용으로 개발되어 왔으나, 최근에는 취미 및 미디어 촬영 등을 위하여 민간분야로 확산되고 있다. 하지만 이러한 무인기를 운영하기 위해서는 유인기와 같은 수준의 안전성을 확보할 필요가 있다. 이는 무인기가 유인기와의 충돌이나 추락에 의해 지상 피해를 유발할 수 있기 때문이다. 본 논문에서는 미국과 유럽의 국가들을 중심으로 소형무인기 운용을 위한 입법 및 운용 승인제도에 대해 조사하였다. 또한 소형무인기 운영을 위한 국내 제도 마련 방안에 대해서도 연구하였다.

There exists historically intimate relationship between the fisheries of the three countries of Northeast Asia in terms of the same fishing ground and similar resources. This means that if one of the countries fail to manage their fisheries properly, it will harm the others. Especially, if the EEZ straddling and Trans-Boundary Fish Stocks aren't managed by the cooperation of the three countries, the exhaustion of resources will be more likely to be accelerated. Considering the aspects mentioned, this paper refers to the necessity of fisheries cooperation between Korea, China, and Japan. Next, it analyzed the joint control cases of Norway/Russia Management of Shared Fish Stocks in the Barents Sea, Management of South Tasman Rise in Orange roughy, Agreement on Fisheries between the European Economic Community and the Kingdom of Norway, Conservation and management of pollack resources in the central Bering Sea, and drew a conclusion for ourselves. Last of all, it suggests a step-by-step strategy of promoting joint control between three countries, and the plan of the establishing and managing the organization of joint fisheries control. About the joint control, "The Joint Statement of promoting collaboration between Korea, China, and Japan" has been announced at ASEAN in October 7th, 2003 and the summit talk of the three countries. In the joint statement, the three countries came to an agreement which says, "Cooperation in Fishery Resource Conservation : The three countries will cooperate, bilaterally or trilaterally, to promote the sustainable use and conservation of fishery resource through the effective fishery management". Not only the consistent collaboration between the government is necessary, but also continuous exchange and related study on a Non-governmental level is also needed for the viable outcome in the near future. When deducting the result for the joint fisheries control, this writer hopes the contents of this study will be helpful.

도시지역에의 내수침수는 주로 우수관로 배수체계의 통수능력 부족으로 발생된다. 따라서 지금까지의 도시침수에 대한 국내외 연구가 우수관로해석에 국한되어왔다. 하지만 우수관로시스템 해석을 통해서 배수능이 부족한 관거를 찾는 것만으로 침수방지대책을 세우는 것은 매우 근사적이고 비합리적인 대안을 제시할 수밖에 없는 실정이다. 본 연구에서는 도시침수양상에 대한 정확하고 합리적인 해를 도출하기 위하여 ILLUDAS를 이용한 관로시스템 해석과 2차원 지표류 계산모형을 연계한 침수해석 모형을 개발하였고, 2001년 7월 서울지역의 집중호우 사상에 대한 적용결과로 해석결과를 검증하였다. 표고차가 적은 도시유역에서 침수모의를 위해서는 2차원적 홍수전파양상을 반드시 고려해야 침수범위, 침수위 등에 대한 정확한 해석이 가능할 것으로 판단된다. 본 연구결과는 도시 홍수 예경보와 침수지도 작성 등의 도시치수 및 방재계획 수립에 실제적으로 응용될 수 있을 것으로 기대된다.

The Kepler(NASA) and CoRoT(ESA) space telescopes are surveying thousands of exoplanet for finding Earth-like exoplanets with similar environments of the Earth. Then the TPF(NASA), DARWIN(ESA) and many large-aperture ground telescopes have plan for spectroscopic observations of these earth-like exoplanets in next decades. Now, it has been started to simulate the disk averaged spectra of the earthlike exoplanets for comparing the observed spectra and suggesting solutions of environment of these planets. Previous research, the simulations are based on radiative transfer method, but these are limited by optical models of Earth system and instruments. We introduce a new simulation method, IRT(Integrated Ray Tracing) to overcome limitations of previous method. The 3 components are defined in IRT; 1)Sun model, 2)Earth system model (Atmosphere, Land and Ocean), 3)Instrument model. The ray tracing in IRT is simulated in composed 3D real scale space from inside the sun model to the detector of instrument. The Sun model has hemisphere structure with Lambertian scattering optical model. Atmosphere is composed of 16 distributed structures and each optical model includes BSDF with using 6SV radiative transfer code. Coastline and 5 kinds of vegetation distribution data are used to land model structure, and its non-Lambertian scattering optical model is defined with the semi-empirical "parametric kernel method" used for MODIS(NASA) and POLDER(CNES) missions. The ocean model includes sea ice cap structure with the monthly sea ice area variation, and sea water optical model which is considering non-lambertian sun-glint scattering. Computation of spectral imaging and radiative transfer performance of Earth system model is tested with hypothetical space instrument in IRT model. Then we calculated the disk averaged spectra of the Earth system model in IRT computation model for 8 cases; 4 viewing orientation cases with full illuminated phase, and 4 illuminated phase cases in a viewing orientation. Finally the DAS results are compared with previous researching results of radiative transfer method.

The importance of urban and regional natural park increases because of the needs for preserving the natural resources and providing with natural recreation space in nature. This planning of natural park management should be established based on the research of the various natural resources in the park. But for the lack of effective data synthesizing methods and concepts, only some restricted factors for zoning plan are considered even though GIS computer system for large complex simulation is used. Therefore, in this study three ecological zoning models such as Basic Factor Model (BFM), Visual Landscape Model (VLM) and Comprehensive Ecological Model (CEM) are proposed and applied to Byounsan Peninsula Nature Park(BPNP) for comparison with the current natural park zoning. The BFM has three components -elevation, slope and vegetation. The VLM has applied with six components -elevation, slope, vegetation, road type, and the visual distance. Finally the CEM's modelling factors have included all of BFM, VLM components are added with the land use type, nature and historic resource factors. The zoning concept of BPNP was based on "Minimization" focused on the specific factors. But introduced modelling concept is "Optimization" based on the total ecological environment. So the result of the modelling has larger area for preservation and development zoning compared with the current zoning whose characteristics are ambiguous which allows the environmental destruction. The future study issues will be the determination of the weighting factor, component reconsideration based on the ground truth data and the agriculture residential area zoning.
