To quantitatively measure or evaluate aesthetic factors is not easy in comparison with physical, functional, behavioral or economic factors. Yet aesthetic factors essentially play an important role in design modeling process. Despite its importance, research on aesthetic assessment or the interaction of aesthetic influential elements is insufficient. Therefore, this study is intended to find the relationships between visual preference and aesthetic variables of perceptual-cognitive dimension and affective dimension in commercial space design. According to the result of this substantiation research, aesthetic variables that give a positive effect on the preference of commercial space design are unity, order, and clarity in perceptual-cognitive dimension and 'pleasant', 'relaxing' in affective dimension. On the other side, aesthetic variables that give a negative effect on the preference are contrast, complexity, and ambiguity that is a contrary concept of clarity in perceptual-cognitive dimension and 'exciting', 'arousing' in affective dimension.

Housing market is segmented through 1) housing supply classified by housing characteristics and 2) housing demand classified by different housing opportunity of household. Moreover, neighborhood plays a role in intensifying housing market segmentation as a factor affecting on decision making relevant to housing supply and demand. while segmented housing markets have different mechanism, existing studies on residential differentiation and housing market have overlooked the characteristic differences among housing submarkets as the studies presume metropolitan housing market to be a single housing market. while the concept of 'residential differentiation' pays much attention on spatial pattern after the ecological approach appeared, the concept of ‘housing submarkets' is explanatory of the process of urban space structure formation. Analysis on housing submarkets makes up for the weak points of the behavioral approach inquiring into socio-economic constraint and different housing opportunity of household.

Variables representing neighborhood quality should be included in hedonic price models to control lfor the influences of negative or positive externalities from the quality of neighborhood on urban housing prices. This study proposes a GIS-based method to effectively measure the neighborhood quality variable when data on the neighborhood quality are aggregated by census sub area. This study also tests the superiority of the proposed neighborhood quality variable created by intensive use of GIS operations to a neighborhood variable not based on GIS operations in explaining the housing price variations by using Seoul＇s apartment sales data. The results from this study show that the neighborhood quality variable based on GIS-based operations shows better performance in explaining the urban housing price variations in Seoul＇s housing market. The implication from the results is that the potentials of GIS-based spatial operations in creating neighborhood quality variables should be well acknowledged by the researchers in the area of urban housing market study and GIS-based spatial operations should be more actively applied to generate better neighborhood quality variables for hedonic price models.

Purpose: This study is focus on investigation of user's spontaneous behavior in the public space of ward where chronic patients are hospitalized. Methods: The notion and necessity of social healing environment is analyzed by literature review. User's location and behaviour are investigated for analyzing behavior by visiting the six wards. Results: The result 1) Stay is main behavior of users. 2) The frequency of stay is high in the place where are planned as the dayroom, the program room and the balcony. 3) In the corridor, the users are staying around court and single side corridor. And the users who are staying in the ward planned middle corridor and double corridor are spreaded all over the corridor. As the result of the analysis of correlation between frequency of user for stay and area of public space, 4) The area of the dayroom, the program room and the balcony is bigger, the frequency of users are higher. 5) There is no correlation between area of corridor and frequency of users. 6) When the density of user is highest in the place for stay, one person occupied $1.96m^2$. Implications: Hereafter the public space, which social healing environment is considered, is planned, this study could suggest the directions of architectural planning about area.

This study aims to calculate reasonable carving capacity of the Gwangneung area and to review its tourism policies from the perspective of the tourist's demands. According to the analysis results, The socio-psychological carrying capacity by targeted intervals of time is generally underestimated and less than desired. Parking lots followed by stores and then roads are the biggest issues weighing down the area's carving capacity Also, another finding shows that the physical carrying capacity, analyzed based on area use, is estimated for 600 tourists and 130 cars. This study recommends following that Gwangneung establish various tour programs linking its cultural and historical sites to forest and ecological resources. Further to this, Gwangneung might be better off exerting efforts to developing environmental education programs and training more cultural and ecological guides. The findings necessitate that should be made off limits to cars, and instead servicing the area with shuttle buses. Management offices can also be classrooms used for cultural, historical and ecological education and exhibitions. Other findings suggest an expansion of convenience facilities such as more potable water stations, benches, resting areas and a continued monitoring of tourism activities in the area.

Cellular Automata(CA) have been investigated and utilized as a theoretical framework and/or methodology for analyzing and simulating the properties and behaviors of many complex systems in various physical science and engineering field. Due to the conceptual elegance and effectiveness of implementing spatio-temporal dynamic models and the compatibility with raster GISs, recently a variety of modeling works using both CA and GIS have been published in GIS fields Most of spatial dynamic models introduced in previous research, however, were very limited and furthermore integrated CA-GIS system for practical modeling purpose are not developed yet. This study aims to develop an integrated CA-GIS system in which a CA simulator is used as an analytical engine for GIS providing a multipurpose spatial dynamic modeling functionalities. This integrated CA-GIS system is anticipated radically enhancing the current lacking dynamic modeling functionalities of GIS and being utilized as an powerful and effective tool for practical spatial dynamic modeling research.

With the advent of the fourth industrial revolution, studies on driving management and driving strategies of autonomous vehicles are emerging. While obtaining microscopic traffic data on vehicles is essential for such research, we also see that conventional traffic data collection methods cannot collect the driving behavior of individual vehicles. In this study, UAV videos were used to collect traffic data from the viewpoint of the aerial base that is microscopic. To overcome the limitations of the related research in the literature, the micro-traffic data were estimated using the multiple object tracking of deep learning and an image registration technique. As a result, the speed obtained error rates of MAE 3.49 km/h, RMSE 4.43 km/h, and MAPE 5.18 km/h, and the traffic obtained a precision of 98.07% and a recall of 97.86%.

Contemporary human beings have tendency to orient themselves to a natural environment while they have adapted themselves to artificial surroundings, which implies that a development of interior space where man, nature and space are in a sympathetic harmony with one another through overcoming non-naturalness and non-humanization is seriously needed. There are two methods in that; one concerns an introduction of environment-friendly expressions into the interior space as its natural factor, and the other involves expressing natural objects or beauties with orderly change commonly seen around in form of artificial design. On this study, the definition of ″Environment-friendliness″ and how it has evolved itself with time are first considered to search out for environment-friendly characteristics in the interior design. And then, among the characteristics of environment$.$friendly expressions widely observed in the interior space, the two aspects are studied for our purpose; an introduction of natural factors and an expression with artificial design. For the study, public facilities located in Ulsan were proposed since they accommodated lots of people. To meet the needs of the times that the development of environment-friendly space should reflect the factors of beauty and comfort enough to live in, relevant studies should be more activated and specialized. When there are a wide understanding of and a profound work upon introducing natural factors as well as ones of sound design into the interior space, a desirable environment-friendly expression could be created.

The study on how visitors of a museum view exhibition is necessary for providing quality experience to the visitors. Previous studies on the movement of visitors of a museum focused on qualitative analysis after the follow-up survey. Therefore, the purpose of this study is to find out various ways to use quantitative analysis methods on the movement of visitors in the museum. Quantitative analysis of the exhibition place and movement of visitors was conducted using programs to produce quantitative results from the space analysis including VAE, VGA, V-ERAM and ESA. VAE and VGA helped to understand the spatial structure and ESA was helpful to predict how the flow of human traffic would be in the museum. If the programs are used all together, it would be easier to quantitatively predict how the How of human traffic would be in an exhibition room. However, this study is in its infancy, so following studies are necessary based on more data and results of analysis in the future.
