This paper presents about an implementation of Video Transmitting and Receiving System(VTRS) for acquiring test data. The VTRS consists of two parts. The first is Transmitter Unit(TU) that is installed on a missile to acquire various kinds of data and transmit the data to the ground through RF signals. The second is Receiver Unit(RU) that receives the transmitted RF signals and reconstruct those to the original data. To gather a high speed data reliably and securely on the ground, the TU is designed by considering data transfer scheme, data compression, modulation method, encryption technic, link budget, and antenna radiation pattern. Further, a placement method of multiple receiving stations is suggested. The VTRS has been tested on a field to check the link margins and maximum receiving distance in a real environment. Finally, the VTRS is applied to a missile flight test and gathered high speed data reliably.

The unification theory of urban and rural areas emphasizes the organic relationship between the central place and its hinterlands, and pursues the balanced development within the framework of mutual cooperation between urban cities and its surrounding rural counties. Since 1995, 47 urban-rural unified cities have been created. In the respect of urban system, the appearance of the unified cities is a big impact. Because the unified cities are different with the new cities or upgrade cities from 'Eup'(the below level of city), in the character of city size and population density. The objective of this paper is to describe changes in the urban system by unified cities. The Rank-Size regression coefficients are employed as a measure of changes in the urban system. And net population density of cities are used as a variable in analysis of variance. The results allows us to confirm a number of hypotheses. The main effect of changes in urban system transformed the increasing number of cities to the appearance of unified cities. There are some heterogeneities, the character of city size and population density between cities and unified cities, in urban system. So, it is not proper to analyse cities and unified cities as a same urban system.

Recently, the process of institutionalization for company town development has been progressed rapidly, with propose of company section, accept of the central goverment, and interest concentration of local goverments. So, this study firstly set the company town concept, secondly survey the process and the contents of its institutionalization, and fainally suggest its desirable future course. The results of this research can be summarized as follows: First, the company town development should not be simple real estate. development and the regional innovation systems(RIS) such as public-private partnership will be need. Second, the real concept of company town is making a town suitably company activity not simply taking development benefit. The company town development is not for once revitalization of the local economy through simply company attraction but making sustainable charming space so space itself can attract company.

忠州市 洞地域의 土地利用變化에 관한 硏究

류상규 忠州大學校 2002 한국교통대학교 논문집 Vol.37 No.2

In this paper the land use composite rate of each dong region in Chungju is used to calculate land use coefficient of localization and specialization. The land use composite rate are classed in two type, as urban and rural use. As a result (1) Main land use items, high localization and outstanding change, are for factory and school. But the changing trend are in case by case. In case of road use, the coefficient of localization increased during last decade. It means that road construction or widening are proceeded usually in built up area then suburbs. (2) The specialization coefficients of Sung-Nae, Moon-wha, the CBD of Chungju, go into declining. So, Chil-Gum, Yeon-Su, Mok-Hang dong are expected to be new core area of Chungju, and renewal program will be needed in Sung-Nae, Moon-wha dong, present CBD of Chungju.

Space syntax is a set of techniques for the analysis of spatial configurations of all kinds, especially where spatial configuration seems to be a significant aspect of human affairs, as it is in buildings and cities. In this paper, the spatial characters of Chungju National University Campus were analysed in 3 time series. The result of this research wsa summarized as follows. Concentration to campus center area is serious and by topographical factor construction of new building and network that connecting center and outer area is difficult. So, it will be desirable that focus in detailed space improvement work such as subspace development, control of walk space ect. And Space syntax will be used as effective guideline in future planning work.

생태자연도를 활용한 개발가능지 평가 : 충주시 사례 The Case of Chungju

Recently, the concept of ESSD is an universal and standard of planning for developable land assesment. In Korea, the Ecological Map and Land Suitability Assessment Program are provided by public section and used as basic index of spatial planning. This study demonstrates the application of preserved land oriented developable land assesmen through the case study of Chungju. The 1st, 2nd grade and special zones of ecological map, topological characters - slope and level - and water supply preserve area are used as criteria. This study proposes a methodology for land suitability - developable land assesment and the result shows that this method will be a core part of sustainable landuse planning process.

The research described in this paper starts by accepting the basic concepts and methods of the descriptive theory of space, known as space syntax. The aim of this research is to estimate the development planning alternatives in the respects of expansion and integration. So, this research attempted to include the adjacent built up area of planning site in analysing area. And the area is divided in 3 zones, existing built up area zone, connection zone, and new built up area zone. Analysing principal index of space syntax theory against each alternative, it is needed that making new alternative which is based on alternative 3 and improved some parts of it's new built up area zone. This new alternative represents the most desirable intelligibility among the alternatives with increasing of connectivity and integration in it's new built up area zone.

In this study the spread process and its characteristics of Chungju Built up area were analyzed and topographic maps were used. Analysing initial Chungju locational characteristics and projecting the land readjustment projects district onto the topography maps, the diffusion process of Chungju were analyded. The research results are as follows: In terms of the sustainability of the city, it is expected that the incerase of the size of the population and rapid spread of builtup area as 1980’s are difficult in Chunjgu. So, as the basic framework of urban master plan and CBD regeneration plan of Chungju, the portion of the CBD regeneration projecteds should be increased rather than the new development porjects.

In this study, yang-an data created in 1902 were used to identify scale and spatial structure characteristics of Chungju Eupseong at that time. First, the information was classified. Second, mapped to compare with the current map. Third, the location of the walls and the gates were identified. And finaly the road system and the land use characteristics of Chungju Eupsseong could be estimated.

In this research, analyzed population change trend of latest 10 years of Chungju from viewpoint of natural and social factor. Compared Chungju's population change characteristics by comparing Chungju's population change trend with Chungchong-bukdo and our country whole population change trend. Analytical results are as following. First, it is thing by change trend of the whole country that latest Chungju's population increases. But, the change is slight than whole country and Chungchong-bukdo. Second, when see as change of structure of population by age, graying tendency of Chungju is progressing faster than whole country and Chungchong-bukdo. So, as for Chungju, disadvantage is added in increase of population. Third, when compare natural increase level of population, natural increase element of population of Chungju was reduced by about 1/4 level during analysis period.
