Making Inclusive Cities is a new urban agenda for better future cities. Inclusive cities should be conceptualized from multidimensional viewpoints including various academic disciplines beyond a single discipline such as urban planning/design and urban engineering which are primary disciplines to have handled urban challenges. The aim of this research is to propose diverse approaches to examine the concept of the inclusive city. This study examines the inclusive city from the lens of co-evolution, social exclusion, inclusiveness, and amenity, looking forward to more academic attempts to investigate this worldwide urban agenda.

The purpose of this study was to analyze affective characteristics and the demands of elementary science gifted students on gifted educations in urban and rural areas. The subjects were 196 science gifted students. The survey questionnaires were consisted of self-esteem, interests in science, scientific attitudes, and demands regarding gifted classes. The results of this study were as follows. First, self-esteem and interests in science, particularly interests toward science, toward science learning, toward science related careers, in urban gifted students were higher than those in rural areas. Whereas interests toward science activities and science anxiety of science gifted students in rural areas were significantly higher than those in urban area. Furthermore, scientific attitudes of science gifted students in urban area were higher than rural those in open-mindedness, critical-mindedness, voluntariness, creativity, whereas science gifted students in rural areas were higher than urban those in cooperation. Second, for the analysis on demands regarding class contents and methods, 'teaching content that challenges and exciting stimuli' of science gifted students in rural areas were significantly higher than those in urban area. Third, for the analysis on demands regarding educational environments, 'satisfaction with class materials provided by gifted classes' of gifted students in urban area were higher than those in rural area.

NDVI (Normalized Difference Vegetation Index) plays an important role in surface land cover classification and LST (Land Surface Temperature Extraction). Its characteristics do not full carry the information of the surface cover typically in urban areas even though it is widely used in analyses in urban areas as well as in vegetation. However, abnormal NDVI values are frequently found in urban areas. We, therefore, examined NDVI values on whether NDVI is appropriate for LST and whether there are considerations in NDVI analysis typically in urban areas because NDVI is strongly related to the surface emissivity calculation. For the study, we observed the influence of the surface settings (i.e., geometric shape and color) on NDVI values in urban area and transition features between three land cover types, vegetation, urban materials, and water. Interestingly, there were many abnormal NDVI values systematically derived by the surface settings and they might influence on NDVI and eventually LST. Also, there were distinguishable transitions based on the mixture of three surface materials. A transition scenario was described that there are three transition types of mixture (urban material-vegetation, urban material-water, and vegetation-water) based on the relationship of NDVI and LST even though they are widely distributed.

In the midst of growing demand for rural life of urban dwellers, this study tried to investigate the difference in behavior and recognition about urban rural exchange between Korea and Japan. For this, this study utilized 2,000 total samples of the survey conducted by MLIT in Japan, because Japan has experienced a low birth rate and aging population earlier and actively promoting urban rural exchange program than South Korea. The result of the analysis is as follows. First, the needs for rural life of urban dwellers are similar both in Japan and South Korea. However, Japanese prioritize future efforts to current efforts. Second, urban dwellers' activities in rural areas were classified into three categories; field trips and hands-on activities, cruise and circulating activities, and leisure activities. Third, similarly three types of visit or intercourse of urban dwellers into rural areas were classified; repeatedly visit the same place as 'iterative type', visit a new place as 'new pioneer type', and not yet determined as 'undefined type'. Variables such as age of household, income, number of inmate, and number of children were analyzed linked to these three types of visit or intercourse in a Discriminant analysis. As a result, only 'age of household', however, turned out to be the crucial factor which influence decisively distinguishing characteristics of these three types of visit into rural areas.

The study of how buildings affect wind flow is an important part of the research being conducted on urban climate and urban air quality. NJU-UCFM, a standard $k-{\varepsilon}$ turbulence closure model, is presented and is used to simulate how the following affect wind flow characteristics: (1) an isolated building, (2) urban canyons, (3) an irregular shaped building cluster, and (4) a real urban neighborhood. The numerical results are compared with previous researchers' results and with wind tunnel experiment results. It is demonstrated that the geometries and the distribution of urban buildings affect airflow greatly, and some examples of this include a changing of the vortices behind buildings and a "channeling effect". Although the mean air flows are well simulated by the standard $k-{\varepsilon}$ models, it is important to pay attention to certain discrepancies when results from the standard $k-{\varepsilon}$ models are used in design or policy decisions: The standard $k-{\varepsilon}$ model may overestimate the turbulence energy near the frontal side of buildings, may underestimate the range of high turbulence energy in urban areas, and may omit some important information (such as the reverse air flows above the building roofs). In ideal inflow conditions, the effects of the heights of buildings may be underestimated, when compared with field observations.

For building an urban image, various elements such as symbolic building, ethnic characteristics, historical background, natural environment, and diverse cultural elements can influence on it. Many cities in developed countries are showing their unique urban image reflecting their own culture, history, and aesthetic tastes. Especially color, one of the major design elements, has greater impact than other visual factors to form an urban characteristic. Despite the long history and cultural background, Seoul as a capital city of Korea does not show an unique city image with the perspective of color. Recently, Seoul has been designated as '2010 World Design Capital' and implements various urban design projects. As a leading city of design, Seoul is trying to make its urban identity through the own symbolic environment color. The purpose of this study is to find an environmental color scheme for developing a desirable urban design through several cases of foreign countries. For the purpose, Paris, London, Amsterdam, and Tokyo were selected as case cities. Each of the cities showed their own cultural characteristics and made their unique urban image by appropriate usage of their natural environment, symbolic building, emblem of country, and so on. We need to consider these successful cases to build up the image of Seoul.

The objective of this study is to analyze the characteristic of radiation environment in the urban and rural through the field observation in the summer. The radiation balance was compared through the measurement of the shortwave radiation and long-wave radiation in the urban, sub-urban, and rural. The following conclusion could be obtained from this research. (1) In the results of observation including the rain-day, it was found that the short wave radiance in the urban is lower about 10% than the rural. (2) The upper part of atmosphere layers in the urban area absorb much short wave radiation energies compared with the rural relatively. It can increase the temperature of the upper part of atmosphere layers and the emittance of long wave radiation. (3) The ratio of the downward short wave radiation to the downward long wave radiation was 1.24 for the urban, 1.28 for sub-urban and1.35 for rural. It can be estimated that the atmosphere condition of the rural is better than that of other areas.

Theory of the building heat transfer is generally limited to the heat flux to the surfaces of windows and walls, which influences the indoor climate of a building, in the field of architectural environmental engineering. While the heat flux from the buildings to their environment has been considered in the viewpoint of urban climate, its conventional theory have been rarely examined. The purpose of this study is to propose a building-urban heat transfer model for defining the relation between the building and the urban climate by extending the building heat transfer model. In this study, the extended building heat transfer model, where response factor method is used, is established on the urban space and the indoor space by the boundary of building envelopes. Computer simulation (HASP/ACLD) is conducted on the subjected urban area by the established building-urban heat transfer model. As a result it is logically proved that the short waves of solar radiation, which interact with long Waves of radiation from the buildings and the earth, increase the urban air temperature ana buildings largely influence on the urban climate.

Purpose: The purpose is to analyze a relationship between urban characteristics and individual characteristics on the health level of individuals. Method: This study analyzed the relationship between urban characteristics and individual characteristics on individual health level in 2016 for local governments in Korea using a hierarchical linear model. Results: It was found that urban characteristics, along with individual characteristics, have a significant effect on the health level of individuals. Although the degree of influence is very large, some variables are not statistically significant, so more detailed research is needed for future urban policy. Conclusion: Although urban characteristics affect an individual's health level, additional research is needed on the variables of individual urban policies.
