급격한 산업화 과정을 거쳤던 우리나라는 무분별하고 무계획적으로 형성되어 양적으로 팽창된 도시들이 현재는 건축물들의 노후화와 인구 공동화 현상 등 도시의 쇠퇴화가 진행 중이다. 도시재생사업이란 노후화된 건물들의 물리적인 개선과 더불어 질적인 기능의 연계도 함께 이루고자 하는 방안을 의미하며, 우리나라에서 도시재생사업은 재정비촉진 사업이란 형태로 이루어지고 있다. 이는 기존의 건설사업과는 기간, 규모 등에서 많은 차이가 있으며, 도시재정비촉진 지구내의 개별적인 사업들이 실행되어지면서 목적에 달성하지 못하는 많은 문제점이 발생하고 있다. 본 연구에서는 도시재생사업에 대한 고찰을 통해 사업의 특성을 파악하고, 개별적으로 수행되는 사업들의 효과적이며 체계적인 관리능력의 부재의 문제점을 파악하고, 그에 따른 대처 방안으로서의 종합사업관리 방식의 적용 가능성을 제안하였다.

Pusan has experienced some different paths of urbanization and industrialization compared to other cities. and has faced the problem of over-saturation In enoronmental capacity. Pusan needs to fond out sustainable development strategies based on Agenda 21 by UNCED In 1992 to secure urban renewal. Therefore. Pusan's sustainable development strategies focus on the 1)research on envlronmental capacity and reasonable population accommodation 2)supp1y of basic enoronmental facilities for the human settlement 3)protection and efficient management of environmental pollution 4)saving and control of energy and other resources S)independent and stable euecution of plan based on biological relation 6)harmony between nature and urban spatial organization. In addition. these policies can be suggested along with the conclusions; First, ostablishment of green plan-muddle and long term environmental goals Included In the urban planning to reduce enoronmental deterioration and pollution. Second, computation of sustalnability Indeu the Index Is necessary to sustainable urban development, which is related with green GNP of the national level. Third, capacity estimation of nature and social environment-estimation of enoronmental capacity to the civilized area is required become an ecopolis, and is required to focus on the western area of Pusan which has high decree of potentiality.

Stormwater reduction plays an important role in the safety and resilience to flooding in urban areas. Due to rapid climate change, the world is experiencing abnormal climate phenomena, and sudden floods and concentrated torrential rains are frequently occurring in urban basins and the amount of outflow due to stormwater increases. In addition, the damage caused by urban flooding and inundation due to extreme rainfall exceeding the events that occurred in the past increases. To solve this problem, water supply, drainage, and water supply for sustainable urban development, the water management paradigm is shifting from sewage maintenance to water circulation and water-sensitive cities. So, in this study, The purpose of this study is to examine measures to increase the resilience of urban ecosystem systems for urban excellence reduction by analyzing the effects of green infra structures and LID techniques and evaluating changes in resilience. In this study, for simulating and analysis of runoff for various stormwater patterns and LID applications, Storm Water Management Model (SWMM) was used.

Den have been many construction projects in urban n We have a lot of problems which have to be solved especially against residence complaints existing building damage due to construction worts. We sometimes have to pay a certain amount of cost to solve the above problem, not in planning. In addition to, we have to suffer from work delay due to confronting problem. Almost all of these are due to blasting work to break solid rock to be excavated. Therefore, this study is focused on finding out how to reduce noise more cheaply. Four cases(4) as cheaper but more effective way have been tested to find out which way of local fence will have better moise reduce function in a field site. Where five(5) large breakers are being operated. It is concluded that more form and shape of local movable panel than the site of panel can be influenced on noise reduce.

With the rapid development of urban traffic system and fast increasing of vehicle numbers, the traditional centralized ways to generate the source-destination shortest path in terms of travel time(the optimal path) encounter several problems, such as high server pressure, low query efficiency, roads state without in-time updating. With the widespread use of smart cameras in the urban traffic and surveillance system, this paper maps the optimal path finding problem in the dynamic road network to the shortest routing problem in the smart camera networks. The proposed distributed optimal path generation algorithm employs the delay routing and caching mechanism. Real-time route update is also presented to adapt to the dynamic road network. The test result shows that this algorithm has advantages in both query time and query packet numbers.

The purpose of this study was to develop a Korean Coping Strategy Scale and to examine coping characteristics of Korean housewives form urban low-income families using this Scale. Two hundred and forty mothers were either interviewed or filled out this Coping Strategy Scale and Demograpic Information Questionnaire. The Coping Strategy Scale consisted of 14 items under 4 dimensions of problem-solving, support-seeking, emotion-regulation/explosion, and abandonment. Item analysis and construct validation were found acceptable. The alpha coefficient of the Scale was 73. The results showed that the mothers used problem-solving most as a coping strategy, followed by supportseeking and emotion-regulation/explosion. Abandonment coping strategy was used least frequently. The demographic variables of mother's and their husbands' age, duration of marriage, income and expenditure per moth were significantly related to mothers' coping strategies.

Most of gas turbine combined cycle power plants are located in urban areas to provide peak load and district heating. However, NOx(nitrogen oxides) of exhaust gas emission from the power plants cause additional fine dust and thus it has negative impact on the urban environment. Although DLN(dry low NOx) and multi-stage combustors have been widely applied to solve this problem, they have another critical problem of damages to combustors and turbine components due to combustion dynamic pressure. In this study, the effect of different fuel ratio on NOx emission and pressure fluctuation was investigated regarding two variable conditions; combustor stages and power output on M501J gas turbine.

As economy and population have been growing, air pollution problems both in local and regional scale came to the surface in East Asia in last decades. In addition to urban problems, regional air pollution is also becoming a big issue international concern. Urban and regional air pollution issues are closely related and we have to tackle the problem by understanding underlying scientific reality and taking a strategic approach to mitigation. (omitted)

This paper proposes the method to develop information system for maintenance of urban transit. We have to develop the standard information system, but have difficult to get user's requirement. To solve this problem, we propose the method, web-based, component-based, and prototype-based development method. Proposed method may provide a procedure to develop information system that have hard to get user's requirement.

This study aims to inquire the sense of place. As an example, I present some conflicts over the right of coal spilled into the sea during coal loading which had occurred frequently in the formation and development period of the Chikuho coalfield (Chikuho-tanden) and Wakamatsu Port located in the northeastern part of Fukuoka Prefecture.
