Contradictions often occur between the process of urban modernization and protection of history and culture, which have become the topics of current studies. The development of a city has its past, present and future while history and culture have their continued process. Culture is the sediment of history, left among buildings and merged in life. Exerting a subtle influence on the construction of a city and behaviors of citizens, culture is very important to the urban construction and is also the soul of a city and its buildings. Culture is closely bound up with inhabitants' life and the key to protect well the cultural features is to protect well historical and cultural venues. Qushuiyuan Garden is a venue for local folklore activities. The programming holds that folklore, historical and humane sceneries should be protected and left to our coming generations.

Urban landscape represents a city's internal identity as well as external form. Therefore, urban landscape and image planning has to involve marketing strategies to deliver the economic growth and regional revitalization through recreating the environmental and cultural value of the city. This study intends to develop practical city image management programs as city marketing tools which consider opinions of local authorities, related experts, and residents. To achieve this purpose conjoint analysis was applied on three components which symbolically reflects features of assets and resources in Anseong. This study can be summarized as follows: 1. The first consideration for Lake Geumgwang is to develop farm experience Programs on waterside fields. 2. The rot consideration for Bauduki Festival is to make efforts for public relations(PR) to be able to merchandise festival-related goods and develop unique products. 3. The first consideration for Anseong Grapes is to build leisure-oriented theme parks for local farm products. This study is meaningful to develop the efficient and quantitative management method of city image for marketing. The integrated approach to the management programs to reflect opinions of local policies, experts and citizens is expected to become a useful foundation in studying city images and marketing.

Traffic congestions are rapidly increasing in urban areas. In order to reduce these problems, it needs real-time data and intelligent techniques to quickly identify traffic activities with useful information. This paper proposes a Fuzzy Domain Ontology(FDO)-based opinion mining system to monitor the transportation network in real-time as well to make a city polarity map for travelers. The proposed system retrieves tweets and reviews related to transportation activities and a city. The feature opinions are extracted from these tweets and reviews and then used FDO to identify transportation and city features polarity. This FDO and intelligent prototype are developed using $Prot{\acute{e}}g{\acute{e}}$ OWL (Web Ontology Language) and JAVA, respectively. The experimental result shows satisfactory improvement in tweets and review's analyzing and opinion mining.

The two-phase turbulent flow past an interface-piercing circular cylinder is studied using a high-fidelity orthogonal curvilinear grid solver with a Lagrangian dynamic subgrid-scale model for large-eddy simulation and a coupled level set and volume of fluid method for air-water interface tracking. The simulations cover the sub-critical and critical and post critical regimes of the Reynolds and sub and super-critical Froude numbers in order to investigate the effect of both dimensionless parameters on the flow. Significant changes in flow features near the air-water interface were observed as the Reynolds number was increased from the sub-critical to the critical regime. The interface makes the separation point near the interface much delayed for all Reynolds numbers. The separation region at intermediate depths is remarkably reduced for the critical Reynolds number regime. The deep flow resembles the single-phase turbulent flow past a circular cylinder, but includes the effect of the free-surface and the limited span length for sub-critical Reynolds numbers. At different Froude numbers, the air-water interface exhibits significantly changed structures, including breaking bow waves with splashes and bubbles at high Froude numbers. Instantaneous and mean flow features such as interface structures, vortex shedding, Reynolds stresses, and vorticity transport are also analyzed. The results are compared with reference experimental data available in the literature. The deep flow is also compared with the single-phase turbulent flow past a circular cylinder in the similar ranges of Reynolds numbers. Discussion is provided concerning the limitations of the current simulations and available experimental data along with future research.

This study tries to view the social and public roles of roads in urban structure in a renewed way, focusing on NakAn-Eupsung, which was a spontaneous settlement, not a designed city, of the many traditional villages. The most valuable meaning the alleys of traditional villages give us is the community of cooperation. Thus, this study tries to examine the features of the community in three major ways happening on the alleys of NakAn-Eupsung in three major ways. First, the features according to regional community; second, the features by social community; third, the features according to public community. Through this, we can understand the features of alleys within the building structure of traditional villages, and also we can have a chance to grasp the image of 'togetherness-of-the-public', long lost on contemporary alleys. In order to realize the ideal of sustainable residence, the techniques of housing complex project are continually being developed, and recently it is not hard to come across the flow of planning techniques taking especially community into consideration. At this point of time, it seems that various kinds of communities being made up on roads of traditional villages can present new directions and models to contemporary housing complex formation.

The Mesopotamia civilization is developed by physical geography. It began from Sumer civilization at BC 3800 and finished to Assyria and Babylonia civilization at BC 600. Therefore, to examine the changing process of the city of 3,000 years standing, it is important to know the elements of the influence to the initial human civilization and city. This study analyzed the 13 cities, that the city were among the 30 the city in same age. As a result of this study, firstly, functions of the city were gradually transition from the farming culture to the functions of commerce, trade, and military. Secondly, the location of the city was gradually move into northern from southern, it is associated with features of the city. Thirdly, the aspect of urban form, the hills above the city of Tel's shape was gradually coming down to the plains. So later, became a form of urban planning undisturbed terrain. fourthly, urban structure has slowly changed from the temple based city to palace based city.

At the present stage of the world economic development, a new economic system is being formed, in which non-economic values, in particular environmental and social parameters, have become widespread. A new vision of economic activity is being formed, which acquires the qualities of Smart-economy. The purpose of this paper is reveal the features of managing the development of smart cities as specific entities of the Smart-economy. New functions of economic entities are formed within the framework of the Smart-economy concept, while their role and weight in the localities' activity or formation have changed. Determining that the key trends in the Smart-economy development are such as digitalization, greening, socialization, institutionalization, and urbanization, this is necessary to note that all these trends are most active in the formation of urban ecosystems. These trends are determined by the general population growth and the urban population growth, which requires considerable attention to planning each city's development itself. Such planning could ensure the comfort of living for all its inhabitants, quality, safe, and modern life. The Smart-city's key elements and the intellectualized approach implementation planes to the decision of these or those tasks are definedIt is determined that a new ecosystem of governance is being formed.

This study aims to find out the genetic characteristics of gridded subdivision area which has its origin from ancient local administrative city-Sangju, Jeonju, Namwon, Kwangju, Chungju. The spatial structure, based on the inter-relationship among gridded subdivision area, city wall, and topographic condition, and the morphological characteristics of gridded subdivision area are analyzed. The points of analysis on morphological characteristics of gridded subdivision area consist of the size of unit block, the organization system of unit block, the orientation of subdivision line. As a result of the analysis, three main characteristics are found. Firstly there can be found no same land subdivision rule among study areas. Secondly, the morphological features of study area were the products of cumulative process of different subdivision areas which were developed in different periods. Thirdly, the original regular gridded land subdivision seems to have been carried out in the object of a farm-land cultivation around 7th century. And there was a change of land-use from farm land to urban land-use during the later 7th century and 8th century.
