A Ubiquitous-Ecological City (U-Eco City) is the new urban paradigm integrated with ubiquitous-city (U-City) connecting the high-tech IT technology to the urvan space with the concept of the sustainable eco-city. As a U-Eco City is attempted for the first time domestically and internationally, there is insufficient discussions for its develoment goal, planned design proposal, technology and service element and others. Even if there are plans to build up it, policy and technology, service structuring business and others, it is difficult to assess how it would bring the efficacy. Therefore, the purpose of this study is to present the indicators system to assess a U-Eco City. The results of this study revealed the following; First, the conceptual framework, which was established to achieve sustainable urban quality, can be suggested by establishing its notion of the U-Eco City. The concept of a U-Eco City as established in this study suggests that the economic development in growth-oriented level has to be conducted not only quality of urban environment but also in terms of sustainable to consider the complex impact of various development; Secondly, the developed assessment system has heightened the completeness as the evaluation index through the attitude survey. As a result of questionnaire survey with the subject of specialists and interested party of this study, the urban qualitative aspect is formulated for the stability as a relatively important aspect. For the urban continuity aspect, society, environment and economy have all similar importance, but the environment element was shown to be highest. And finally, subject area was selected on the basis of the evaluation system and the analysis was made on the basis of the implementation design plan of the area. As a result of the assessment, safety and economy have shown to be high. This is indirectly indicated for the priority in economic growth driven development plan unlike the importance of environmental continuity obtained through the attitude survey. When planning on urban development, there is a need for supplementing the environment part and it has to present the connection plan between the economic growth and environmental continuity.

The important of Smart City has been increasing on the driving force of 4^th industrial revolution and method to solve urban problems. Korea government introduced and implemented ubiquitous City as an intrinsic Smart City brand from the early 21^th century. Diverse types of Smart City projects were announced as national strategy by the spatial characteristics. National Test-Beds in Sejong city and Busan(EDC: Eco Delta City) are urban planning to be future city models for new town development. In the old towns in cities, various type of Smart City projects are support by government by urban growth stage; frontiers, stable or declining urban realm. 「3^rd Comprehensive Plan for Smart City(2019 ~ 2023)」 in Korea plans an important role to build innovative ecosystem and reinforce global competiveness by spreading of Smart Cities. For the successful Smart City as open and inclusive space, it is need that this space should be made by the cooperation of citizens, private sectors and local and central government.

The purpose of this study is to analyze the characteristics of the 11 southeastern states in the United States by using regional characteristics variables and to classify the regions. First, 19 variables from four categories of population, society, industry-economy and urban service were selected and factor analysis were conducted, and the result showed five major factors of population, economic condition, job and commuting. Based on the following factor scores, a cluster analysis was conducted, and eight types of big city, medium-sized city, bed town, small town, urban hinterland, retirement town, and rural village were derived. These types of spatial distribution characteristics showed big cities were by different types of regions and they formed metropolitan areas. Each types of classified regions were located along the road network with hierarchy. The study focused on cases in the southeastern regions of the United States and can be used as a comparison with Korean cases. If the same research method is applied to Korea in the future, or if the time series of changes is tracked by analyzing different time points, it will greatly help identify the characteristics of urban and rural mixed areas.

The purpose of this study is to grasp the present state of a outdoor space planning and to analysis plan characteristics in based on regional characteristics in Housing complex plan. The analysis result of this study is as follows : first, we know that the right of regional characteristics is appearing variously every research workers. also an analysis about regional characteristics that should be considered in housing complex plan was insufficient. Second, regional characteristics can be classified into 5 factors. These are classified as a context of location, city link, life atmosphere, needs of locals and creation of image. Third, it has originality against other housing complex to graft items connected with 'U contest' on outdoor space planning. Also, it has affirmatively effected on image of Buk-gu and recognition of Dong beyn-dong and Seo beyn-dong. It is get out of the uniform design by a planning based on land and surrounding environment in arrangement and forms. Also residents have the satisfaction and pride in arrangement considering the climate of a region and security of the green space.

In this study, we have intended to precisely analyze the aspect of propagation and the extent of damage due to the traffic noise as hon as a main source of noise in urban area. The propagation of traffic noise has a strong relationship between distance and shape of surface. Thus, it is necessary to consider the distribution of buildings for estimating effects of noise in urban area because noise propagations will be affected by buildings. For this, we developed the DEM and DBM using the airborne LiDAR data in the study area and compared with results from the noise simulations using the each model. The extent of damage occurred by the traffic noise above 60 dB(A) from the case of DEM were shown at the 60% of a whole study area, whereas the extent from other case of DBM were shown at the 30% of a whole study area. Also, the extent of the noise levels between 45 dB(A) and 50 dB(A) will be generally recognized as calm environment was increased(the 0% to the 43%) in the case which simulated with building informations. These results indicated that the shape informations of buildings like a DBM is a essential source to simulate the propagation of traffic noise in urban area especially. With results in this study, the effect of traffic noise at a specific area will be easily and precisely estimated if we have the LiDAR data and a traffic census for Korea. Furthermore specific area's traffic noise simulation could be possible using only road traffic information once we have DBM data from LiDAR surveying. This also could be applied as a base data for noise pollution petitioning, traffic planning, construction, etc. in huge city planning projects like a U-City.

As social needs are increasing to minimize the occurrence of external effect due to urban development and to diffuse the benefits of development to surrounding areas, diverse cooperative planning methods are increasingly being discussed. In the long term, laws and systems need to be refined to support cooperative planning, but prior to such development, elements, procedures, and methodologies wherein cooperative planning in U.S.A cases could be implemented were examined to derive the alternative to and implications of cooperative planning that can apply not only to single administrative districts but also to complex boundary new towns being developed by various local governments. This paper surveyed and analyzed the cases of Wisconsin State of the U.S.A, thereby deriving the following implications. First, joint planning areas should be established within the boundary area of various local governments to establish cooperative planning areas in special areas such as complex boundary new towns, and to this end, urban planning means should be prepared. Together with such efforts, to boost the flexibility of cooperative planning, life sphere unit-based planning unit should be established, and a well-organized operation system to activate communities should be prepared. Also, revenues, generated through regional growth, should be distributed to individual local governments through joint tax according to the agreed-upon ratios, and as such, measures to share services and operate joint tax in small-size regions should be secured. Together with such efforts, to establish cooperative governance, measures to manage conflicts through the participation by stakeholders and arbitrators should be prepared from the planning stage, and measures for implementing cooperative planning at the level of basic urban planning should be prepared.

Recently, it is appearing that new paradigm of urban planning that ubiquitous concept such as the u-City, uECO-City is introduced while is rising necessity about third dimensional geo-spatial information of high quality for urban area. Orthophoto can manufacture by expense and time that is less easily than digital map using personal computer even if is not highly technician and according as position relation between manmade feature and natural feature is equal, can get information of distance, angle, horizontal and vertical position coordinate of topographic, area etc.. directly through orthophoto. Also, visual effect is good that orthophoto is expressed by image and interpretation is easy to detailed part of topographic. Manufacture and practical use are consisting in various field, for it is having advantage that can recognize information effectively than digital map. Therefore, this study presents a way of generating a detailed DSM for producing a true-orthphoto of the urban area, and this study also presents a way to produce an optimum true-orthophoto for an urban area by investigating through experiment the optimum variable for the geometric and radiometric correction of the orthophoto. This study also examined the potentials of the thesis by building a 3-dimensional city model of the model region with the above thesis on optimum generating method.
