  • 국도의 분류에 대한 연구는 계속되어왔으나 도시간선도로의 분류에 대한 연구는 미진한 편이다. 교통량의 증가로 도시간선도로는 간선도로로서의 역할을 제대로 수행하지 못하고 있다. 본 논문에서는 교통특성변수를 사용한 군집분석을 이용하여 도시간선도로의 기능을 정립하였다. 서울시내 55개의 간선도로의 기능을 정립하기 위해 교통량, 주말계수, 속도 계수 등 교통특성을 사용하였다. 본 논문의 결과와 AADT를 사용한 방법의 결과를 비교하였는데 AADT를 사용한 방법은 전체 차선의 교통량에 의해 특성을 분류하였으나 본 논문에서 실제 교통량을 반영한 차선당 교통량을 주요 변수로 사용하여 결과를 도출하였다. 또한 서울시 간선도로 기능분류와 본 논문의 결과를 비교하여 교통특성이 반영되었음을 증명하였다. 결과적으로 본 논문에서 제시한 방법은 현재 간선도로 기능분류 방법보다 교통특성을 나타내는데 효과적이며 기능분류체계는 도로확장 및 계획 설계에 도움이 될 것으로 판단된다.

  • 도심 지역은 무선 채널 환경 중 대표적인 이동 통신 사용 지역으로서, 건물의 밀집도가 다양하게 분포하는 형태를 보인다. 건물 밀집도의 차이는 신호전달 과정에서 상당한 영향을 미칠 것으로 예상되어, 건물 밀집도의 정도가 채널 특성 분석에 있어서 영향을 미칠 가능성을 고려하여 전파 특성을 분석할 필요성이 있다. 측정은 제주도 인근 도심 지역에서 실시하였으며, 채널 사운더와 $4{\times}4$ 안테나로 채널 특성을 측정하였다. 측정된 데이터를 바탕으로 도심 지역에서 건물 밀집도를 고려한 채널 특성을 도출하였다. 본 논문은 700 MHz 대역에서 도심 지역 건물 밀집도를 고려한 MIMO 시스템의 전파 채널 측정을 통해 측정 데이터를 분석하고, 채널 특성을 도출하였다.

  • 본 연구는 대구시 도심의 토지이용 변화와 재개발의 실태를 파악하고, 도심 공간의 쇠퇴가 토지이용에 어떻게 반영되고 있는지를 고찰하였다. 1980년대이래 우리나라의 대도시가 겪는 공통의 현상으로서 도심의 쇠퇴는 인구뿐만 아니라 경제활동에서도 영향을 미치고 있다. 이 같은 도심의 공동화 현상과 관련하여 도심에서 토지이용을 크게 용도지역과 실제 토지이용의 측면에서 중심상업지구와 주거지역에서 변화를 파악하였다. 그 결과 중심상업지역은 중심상점가에서 상업적인 기능이 강화되고, 업무적 기능은 정체 혹은 쇠퇴로 나타나는데 비해 주거용 토지이용은 다른 용도지역과 혼합되어 나타나지만 실제 개발은 필지 규모의 제약 때문에 도심 공간의 효율화에 저해가 되는 것으로 밝혀진다. 아울러 건축물에 기초한 토지이용 전환의 정도에 의해서 주거용도의 변화정도를 뒷받침하고 있다. 끝으로 도시재개발사업의 일환으로서 도심재개발 사업을 살펴보고, 현재의 문제점과 그 과정을 기술하였다.

  • It is essential to consider strategies, spatial planning, and reflection of sustainability for the creation of sound urban spaces. To this end, there is a need for plans that can secure better sustainability through strategic environmental assessment (SEA) of plans. This study examined the literature and available precedent to develop a SEA model for administrative plans for urban development including metropolitan plans, urban master plans and urban management plans. In the course of development of the model, environmental issues associated with the urban plans were analyzed by classifying them into ten categories, including "spatial planning," "conservation planning," "greenbelt systems," "habitats." and etc. according to their rank. Furthermore, those issues were reflected on the development of environmental evaluation indices for the plans. Overall and detailed environmental indices that can be applied to the administrative plans for urban development including metropolitan plans, urban master plans and urban management plans were devised for five stages: (1) Establishment of development goals and strategy, (2) Analysis of current status and characteristics, (3) Conceptualization of spatial structure, (4) Planning for each department, and (5) Execution and management. Sub plans are more detailed and concrete. Criteria based on the evaluation indices, when performing evaluations on plans based on each environmental assessment index in reference to experts and the literature, were used to forecast their effects, i.e. whether they had a positive, negative, or no effect or relationship, or whether their effects was uncertain. Based on the forecasts, this study then presents means to establish more improvable plans. Furthermore, by synthesis of the effects according to each index and integration of the process, plans were analyzed overall. This study reflects the characteristics of the present time period based on issues in the SEA process and techniques in upper level administrative plans being newly established, and presents them according to the stage of each plan. Furthermore, by forecasting the effect of plans by stage, this study presents proposals for improvement, and in this aspect, can be meaningful in promoting plan improvements through SEA.

  • The purposes of this study are to analyze the meanings of urban spaces which are the background of the Korean films, and to capture the interactions of ordinary culture and urban spaces. By reading urban spaces through films, it is possible to understand the variety of experiences that are hardly captured with direct eyes, specific and vivid urban images, and various events formed by the interactions of spaces and people. The scope of the study is the urban spaces revealed in Korean films portraying cities after the 1960's as their settings, and the total of 18 films was selected with every $4{\sim}5$ films for each time stage. With the selected films, analytical meanings were developed with considering three aspects; 1) phylogenetic meaning that simply reflects social-cultural and historical background, 2) the outer strum meaning that concerns the situation of special background and film scene, and 3) metaphorical and metanymic meaning on films. According to the appearance frequency, spatial backgrounds of film scenes are mainly alleys, main streets, railroad, loft, and riverside. And then the connection between spaces and meaning clusters was grasped, and reflected meanings were derived for every spaces. And the meaning of urban space in films was analyzed based on the meaning of developments and outer stratum. The fundamental characteristics and feelings of people in media such as films are more emphasized than in real world. Urban space is not considered as a simple visible shell, but is recognized as 'a real situation' created by people. The intension of this study was to open the possibility of the various views of urban spaces. The construction of the urban space should be approached from a perspective of creating new places at where the space and human beings interact with considerations of stories of various human lives. I hope new vistas can be opened up for the research subjects and methodologies about the hereafter study of urban spaces through the mutual communications with various adjacent regions including films.

  • Kyoto, which was Japan's political and cultural capital for more than a millennium before the dawn of the modern era, shows distinctive characteristics formed in the process of urban modernization. A citizen plaza perfectly fit to a modern city is lying on the east side, but a delayed urban reconstruction in the city center due to a strong conservative self-government awareness, as well as a delayed modernization of tax system, caused disorderly urban sprawl to appear in the suburbs. Thanks to the enactment of urban planning law enacted in 1919 by the government (Ministry of Internal Affairs) and an increasing awareness about the necessity and rationality of urban planning projects, urban renovation took place at a rapid pace. In the meantime, new ways of urban design were sought for and experimented to conserve it as a historical city against the city' quickly changing landscape.
