In this study, Urban Climate Simulation was performed by 3-Dimensional Urban Canopy Model. The characteristics of urban climate were analyzed combining artificial land coverage, building size, heat production from the air conditioning and topographic conditions as physical variables which affects urban climate characteristics. The results are as follows. (1) The aspects of the urban climatal change is derived to be related to the combination of the building coverage ratio, building height and shading area. According to the building height, the highest temperature was increased by $2.1^{\circ}C$ from 2-story to 5-story building and the absolute humidity by 2.1g/kg maximum and the wind velocity by 1.0m/s was decreased from 2-story to 20-story building. (2) Whole heat generation was influenced by the convective sensible heat at the lower building height and by the artificial heat generation at the higher one over 20-story building influence to some extent of the building coverage ratio. The effect of the altitude is not more considerable than the other variables as below $1^{\circ}C$ of the air temperature. In the last, deriving the combination of building coverage and building height is needed to obtain effectiveness of the urban built environment planning at the point of the urban climate. These simulation results need to be constructed as DB which shows urban quantitative thermal characters by the urban physical structure. These can be quantitative base for suggesting combinations of the building and urban planning features at the point of the desirable urban thermal environment as well as analyzing urban climate phenomenon.

A smart city utilizes data collected from various sensors through the internet of things (IoT) and improves city operations across the urban area. Recently substantial research is underway to examine all aspects of data that requires for the smart city operation. Atmospheric data are an essential component for successful smart city implementation, including Urban Air Mobility (UAM), infrastructure planning, safety and convenience, and traffic management. Unfortunately, the current level of conventional atmospheric data does not meet the needs of the new city concept. New and innovative approaches to developing high spatiotemporal resolution of observational and modeling data, resolving the complex urban structure, are expected to support the future needs. The geographic information system (GIS) integrates the atmospheric data with the urban structure and offers information system enhancement. In this study we proposed the necessity and applicability of the high resolution urban meteorological dataset based on heavy fog cases in the smart city region (e.g., Sejong and Pusan) in Korea.

In celebrating a half century history of the Korean Geographical Society, this paper is concerned about research trends of the urban geography in Korea by reviewing of 449 papers and 15 books mainly in an urban geography field. The findings are summarized as follows: (1) The development of the urban geography in Korea has several stages; \circled1 The launching stage just after 1945; \circled2 the premature stage in the 1960s; \circled3 the taking-off stage in the 1970s; \circled4 the maturing stage in the 1980s; and \circled5 culminating stage in the as of 1990s. (2) The earlier studies had a few limited research themes without major debating issues. In the 1970s, various research themes had been introduced in the urban geography. More diverse themes have been studied in urban geography after the 1980s. The major themes in the urban geography included urbanization, urban structure, urban system, urban economic structure and so on. (3) The most frequent research area for the Korean urban geographers has been the Seoul metropolitan area followed by Kyongsang-Province region. Outside Korea, the most frequent research areas are the American cities followed by the cities of Japan, Canada, and France. (4) The urban geography in Korea has played a major role in introducing the quantitative methods and techniques into geography. For example over 30.5% out of papers in urban geography has taken the quantitative techniques in the past 35 years during the 1960-1994 period. The papers inside urban geography have counted more than 60 percent from research papers in major university journals and took 34.6 percent from the papers of the Journal of Korean Geographical Society.

The relationships between fashion and architecture have been interactive. Since the fashion has had the role to decide the structure type of urban environment, it is becoming the new sign of space boundary. This study searches the social and cultural characteristics of Nomadism and the relationships among all kinds of changing objects. After then, the module system characteristics are meditated by analyzing the composition method of module system in architecture. Moreover, the study examines the aesthetic values in the fashion and body architecture from artistic aspect. Based on the above discussion, the followings are the characteristics of body architecture as the social structures expressed in modern fashion. The liquidity is the fluid form of dynamic structures. It shows the extended space form which produces the continuity. The transformation is the variable structure by module system and it forms the diversified structural combination. The movement combines the controlling function to be able to regulate and move freely the body related objects. The convergence is the text combination interpenetrated mutually in enlarged space. Through this, the non-linear continuity and the access of the individual factors are shown.

The spatial and temporal changes of the annual mean urban heat island(UHI) intensity were investigated using near surface temperature data measured at 16 automatic weather systems(AWS) in Busan metropolitan area(BMA) during the 11-yr period, from 2000 to 2010. For nighttime, the annual mean UHI intensity at Dongnae(U1) in 2000 was weaker than it in 2010. However the change of the annual mean UHI intensity at Daeyeon(U2) during 11 years was different from it at U1. The annual frequency of the UHI intensity over $5^{\circ}C$ considerably increased at U2 and decreased at U1 during 11 years. The center of the UHI also spatially shifted southward with Daeyeon and Haeundae in BMA. It would be caused by the increase of urban area, population-density and transportation near U2 and by the decrease of them near U1. We found that the spatial and temporal differences of the UHI intensity have coincided with changes of land-use, population density and transportation in BMA.

In Korean context, the innovative cities imply new towns or urban clusters in the Non Capital Regions, all of which would accommodate the relocated Capital based public organizations. The central government-initiated innovative cities have provoked pros and cons towards their effectiveness and efficacy for the balanced territorial development. From a broader prospective, this paper firstly examines the current status quo of the innovative cities. Based on their master plans, it analyzes physical and non physical factors which would exert significant impact on the innovative cities. Secondly, it pays attention to how key factors strengthen or weaken their behavioral patterns in terms of dynamic location and implementation policies of the innovative cities. Using System dynamics approaches, it sets up couples of scenarios, categorizing between supporting and opposing arguments towards the innovative cities. Lastly, after divulging systematic structure of the innovative cities, it proposes a series of practical alternatives which would contribute to minimizing unexpected side effects or unwanted social cost in the long run. In order to guarantee reinforcing structure of the innovative cities, the paper suggests that QOL (quality of life) variables, which would require continuous investment in the social infrastructure, are pivotal in achieving original goals of the innovative cities. Otherwise, the innovative cities would not be innovative per se. In the worst case, they might be degraded into the unpopular ghost towns.
