본 연구는 기존 구도심부 상업지역의 공동화로 인한 쇠퇴현상이 나타나고 있어 현 시점에서 진주시의 도시공간구조를 살펴보고자 하였다. 도시공간구조 분석의 범위는 구득자료의 한계와 연구의 목적을 감안하여 진주시의 동지역으로 한정하였다. 진주의 도시공간구조를 밝히기 위하여 다변량해석(Multivariate Analysis)을 사용하여 분석한 결과 7개의 지역(중심지, 공업지, 일반주거지 등)으로 유형화할 수 있었다. 진주시는 장래 낙후된 도시이미지의 쇄신, 서부경남의 중심도시로의 부활을 위해서는 앞서 지역별 현상을 감안하여 도심 노후지역의 전면적인 도심재개발, 재건축사업 및 재정비촉진사업 등이 필요할 것으로 보이며, 상평공단 이전 및 초장동 일원과 연계한 신도시 건설, 현재 계획 중인 혁신도시의 차질 없는 추진이 필요할 것으로 판단된다.

Urban agriculture, which can be defined as agriculture performed in a city, is suggested as an alternative solution to restore deserted community and expand green land in city area through cultivation activities. In Korea, 'Urban Agriculture Promotion and Support Act' was enforced from May 2012. In addition, in the same year, Seoul Metropolitan Government declared 'the beginning of urban agriculture era,' established municipal ordinance, and increased budget to actively support urban agriculture. As a result, urban agriculture practices have been increasing every year. Yet, the way of developing urban agriculture in a uniform way of expanding green land has led to difficulties of securing proper spaces. Accordingly, 'roof top' spaces have gained attention. This study analyzes rooftop garden, one of the spaces of carrying out urban agriculture, from the publicness perspective. The study selected a case study of a public rooftop garden in Mullae-dong, Yeongdeungpo-gu, investigated present conditions and usage features of the garden, and explored the conditions to be a 'public' roof top garden. Through theoretical analysis, both physical and non-physical indicators were derived for analysis framework; physical aspects- accessibility, locality, openness, comfortness, and non-physical aspects- subjectivity, cooperativeness, and a sense of community. The results of this study are as follows. First, openness and locality scores were the highest, and comfortness scored the lowest, in ensuring the publicness of Mullae roof top garden. Second, non-physical indicators had stronger effect than physical indicators on rooftop garden users' awareness on publicness and building a garden community. In conclusion, in order to vitalize roof top garden, users should be engaged from the very first planning stage of building a garden, opening hours should not be limited, and more importance should be put on users to subjectively manage the operation of rooftop garden than merely creating a physical environment.

In recent years, energy consumption in the transportation sector by expanding motorization continues to increase in almost every country in the world. Moreover, the growth rate of the transportation energy consumption is significantly higher than those of the civilian and industrial sectors. Therefore, every country strives to reduce its dependence on private transport, which is the main contributor to the transportation energy consumption. In many countries, concepts such as Transit Oriented Development (TOD) or New Urbanism, which controls road traffic by increasing the proportion of the public transportation significantly, have been implemented to encourage a modal shift to public transport. However, the level of change required for eliminating environmental problems is a challenging task. Minimizing transportation energy consumption by controlling the increase of the traffic demand and maintaining the level of urban mobility simultaneously is a pressing dilemma for each city. Grasping the impact of the diversity of the urban transport and infrastructure is very important to improve transportation energy efficiency. However, the potential for reducing urban transportation energy consumption has often been ineffectively demonstrated by the diversity of cities. Therefore, the accuracy of evaluating the current efficiency rate of the urban energy consumption is necessary. Nevertheless, quantitative analyses related to the efficiency of transportation energy consumption are scarce, and the research on the current condition of consumption efficiency based on international quantitative analysis is almost nonexistent. On the basis of this background problem definitions, this research first built a database of the transportation energy consumption of private modes in 119 cities, with an attempt to reflect individual travel behaviors calculated by Person Trip data. Subsequently, Data Envelopment Analysis (DEA) was used as an assessment method to evaluate the efficiency of transportation energy consumption by considering the diversity of the urban traffic features in the world cities. Finally, we clarified the current condition of consumption efficiency by attempting to propose a target values for improving transportation energy consumption.

불규칙성(irregularity)과 다양성(variety)을 특징으로 한 18세기 낭만주의 조경의 픽춰레스크 미학은 19세기 도시 가로형태에 적용되어 '어번픽춰레스크(Urban Picturesque)'라는 개념으로 불리게 된다. 선행연구가 가로의 어번픽춰레스크 특징 중 물리적 형태에만 국한하여 보행체험의 흥미도에 미치는 영향관계를 보려 했던 한계점을 보완하기 위하여 본 연구는 물리적 측면과 활동적 측면의 양대 인자를 보행흥미 도를 결정하는 변수로 설정하였다. 사례연구에서는 서울의 보행자중심 가로들을 대상으로 하여 '어번픽춰레스크'적 특성에 따른 물리적 측면과 활동적 측면의 설문조사를 통하여 도시 가로설계에서 '어번픽춰레스크' 개념의 적용가능성을 모색 하고자 하였다. 실증적 조사분석을 통한 연구결과는 다음과 같다. 덕수궁길이 물리적으로는 픽쳐레스크한 특징을 더욱 많이 갖추고 있었음에도 실제의 보행흥미도에서는 인사동길이 더 높게 나타났다. 그 이유는, 인사동길이 덕수궁길에서 보이는 가로의 다양한 형태변화의 속성과 명동길에서 보이는 다양한 활동적 측면의 요소, 그리고 가로의 독특한 분위기 등을 동시에 복합적으로 갖추고 있는 가로이기 때문인 것으로 파악되었다. 이로써 도시환경의 물리적인 형태와 활동적인 요소는 복합적으로 작용하여 가로의 보행체험에 영향을 주는 것으로 파악되었다. 결론적으로, 현대도시의 보행자가로에서 '어번픽춰레스크'적 특성이 이용자에게 보다 흥미롭고 매력적으로 느껴지게 하기 위해서는 가로의 물리적 형태와 더불어 각 가로상황에 맞는 활동적 측면이 활성화되어야만 한다는 것을 알 수 있었다.

Because of their exclusive features, millimeter wave directive mesh networks can be considered for small cell backhaul support in urban environments. For this purpose, a network of closely spaced stations has been considered with very directive line-of-sight links operating in the 60-GHz band. An attempt is made to evaluate channel response and interference behavior in such a network, taking into account the effect of building blockage. A simple grid of building blocks is considered as the propagation environment, and wave propagation is simulated using 2.5-dimensional (2.5D) ray tracing (2D with ground effect) to calculate the received signal at different nodes in the network. The results are compared with free space predictions and used to evaluate interference at all nodes in the channel and describe certain characteristics of links, such as the delay profile and the correlation length.

The objectives of this article are to grasp the characteristics of the apartment buildings with commercial facilities through various case studies and to present alternative measures in planning method to the issue of division of space function. To present the alternative planning method on apartment buildings with commercial facilities in urban housing blocks, 34 cases completed in 1990's were chosen in Seoul area. Substantial methods such as field research, close observation and interviews were carried out to analyze on these subjects. The analysis were focused on the sizes and features of apartment buildings and its relationships to other components. Other components can be roughly divided into four sectors which are environments, roads, arrangements of the main building and public facilities and commercial facilities inside the resident blocks.

Urban transit system must secure fast, safe and reliable transportation capacity as a metropolitan mass transit. For this purpose, it is important to make all the sub-systems (which consist of EMU, power feeding, signaling & telecommunication, railway, platform facility, and control system and so on) work well. To operate all the systems effectively and reliably, a maintenance measure optimal to each system's characteristics is needed to be established and executed. So, highly reliable maintenance should be performed. But, EMU maintenance methods suitable to its own model and EMU lines are not yet introduced. This study examined few examples mainly to secure reliability on a maintenance quality in operating method and the features of train maintenance system based on travel distance.

This research is to establish a theme-type organic edu-farm model and provide ways to practically apply it so as to vitalize urban-rural exchange through the emerging concept of green tourism. This research also traces the practical development of organic edu-farm programs. Organic edu-farm(OEF) should be some of the ideas to develop organic agriculture resources according to the local features, and learn by direct and actual experience a life of organic farm. A few policy suggestions to put OEF model in practical use are proposed. What the state needs to do through direct involvement are to put efforts at demand expansion on organic farm products, to clean and beautify the green rural environmental settings, to build more urban-rural exchange facilities. What is more important, however, is financial support, to create the network and to develop program contents for each OEF operation unit. The OEF model proposed in this research will be applied as a relevant reference in planning and realizing sustainable green tourism at the village level.

Waste policy instruments such as garbage bag-fee system and recycling policy initiated in 1995 have contributed to the reduction of solid waste generation. Rural areas now produce less amount of solid wastes in terms of per capital than urban areas and as compare to a decade ago. However, most policy efforts since the early 1990s related to waste issue have been concentrated in urban areas. Waste problems in rural areas are not the amount itself, but the specific characteristics which are unique in rural regions. Large portion of solid wastes and farming wastes are being illegally treated and/or burned out. Surveys show that the main reasons for the illegal treatment of rural wastes are th lack of systematic policy tools targeting on them, insufficient financial capacity and man power of local governments, rural people's cognition problem about wastes, among others. This study reviews current features of the treatment of rural solid wastes and provides policy suggestions for the resolution of the problem.
