The value of culture receives the attention of the world in order to solve urban problems and revitalize cities. Cultural city policies are implemented in Korea and EU to revitalize cities by utilizing cultural values. Although the cultural city policy is effective for urban regeneration, it has not been verified whether it has a positive effect in terms of urban identity and customer-based city brand. This study investigated whether cultural and artistic infrastructure and cultural artistry, which are resources of a cultural city, have a positive effect on urban identity, and whether urban identity affects the brand recognition and the perceived quality of a city. For this study, questionnaires were collected from 208 people residing in Seoul, and empirical analysis was conducted on 206 copies of them, excluding 2 copies of insincere answers. The infrastructure and cultural artistry of cultural and artistic resources showed significant results in the positive relationship between the cultural specificity of urban identity, social system and growth potential. Cultural specificity of urban identity also showed a significant positive effect on city brand equity. In the case of the social system and growth potential of urban identity, there was a significant positive effect on perceived quality, but insignificant results were found in the relationship with brand awareness. Through the results of this study, practical implications can be drawn for cultural city policy implementation and city brand management.

As cities continue to evolve and expand, the importance of accurately modeling and simulating urban environments to predict and assess various risk scenarios has become increasingly recognized. Since city simulation can capture the intricate dynamics of urban life, the versatility of city simulation has been demonstrated in numerous case studies across diverse applications. Owing to this capacity, city simulation plays a critical role in the disaster risk management field, especially in accounting for the uncertainties in natural/man-made disasters. For example, in the event of an earthquake, having detailed information about an urban area is instrumental for evaluating stakeholder decisions and their impact on urban recovery strategies. Although numerous research efforts have been made to introduce city simulation techniques in disaster risk reduction, there is no clear guideline or comprehensive summary of their characteristics and features. Therefore, this study aims to provide a high-level overview of the latest research and advancements in urban simulation under different hazards. The study begins by examining the simulation techniques used in urban simulation, with a focus on their applicability in disaster scenarios. Subsequently, by analyzing various case studies, this research categorizes them based on their unique characteristics and key findings. The knowledge gained from this literature review will serve as a foundation for subsequent research on simulating the impacts of urban areas under various hazards.

Accurate knowledge of land use/land cover (LULC) features and their relative changes over upon the time are essential for sustainable urban management. Urban sprawl growth has been always also a worldwide concern that needs to carefully monitor particularly in a developing country where unplanned building constriction has been expanding at a high rate. Recently, remotely sensed imageries with a very high spatial/spectral resolution and state of the art machine learning approaches sent the urban classification and growth monitoring to a higher level. In this research, we classified the Quickbird satellite imagery by object-based image analysis of Dempster-Shafer (OBIA-DS) for the years of 2002 and 2015 at Karbala-Iraq. The real LULC changes including, residential sprawl expansion, amongst these years, were identified via change detection procedure. In accordance with extracted features of LULC and detected trend of urban pattern, the future LULC dynamic was simulated by using land transformation model (LTM) in geospatial information system (GIS) platform. Both classification and prediction stages were successfully validated using ground control points (GCPs) through accuracy assessment metric of Kappa coefficient that indicated 0.87 and 0.91 for 2002 and 2015 classification as well as 0.79 for prediction part. Detail results revealed a substantial growth in building over fifteen years that mostly replaced by agriculture and orchard field. The prediction scenario of LULC sprawl development for 2030 revealed a substantial decline in green and agriculture land as well as an extensive increment in build-up area especially at the countryside of the city without following the residential pattern standard. The proposed method helps urban decision-makers to identify the detail temporal-spatial growth pattern of highly populated cities like Karbala. Additionally, the results of this study can be considered as a probable future map in order to design enough future social services and amenities for the local inhabitants.

Today, ever growing population density in Seoul or areas near Seoul is problematic. To overcome the problem, the government tries to construct so called, 'New-towns'near Seoul to spread out the population over larger areas. But building new-towns created another problem of traffic between Seoul and New-towns. It can be solved if more public transportation systems such as urban railroads are constructed. In order to succeed in urban railroad construction, we have to make a perfect plan through in depth research on characteristics of the urban train and the construction site. In this paper, we propose a method to design the Decision Support Systems(DSS) using Geographic Information Systems(GIS) and Spatial Analysis for the planning of urban railroad construction.

The control center of an urban railway operator provides railway users with various information on railway use through a 1:N same-time broadcasting system. However, the facilities of the broadcasting system are aging, exposing many limitations in meeting the needs of urban railway users who have become familiar with mobile services. To overcome these challenges, this study analyzed the mobile-based same-time broadcasting services using location information of urban railway users and the requirements of various stakeholders (urban railway users, an operator, and external service providers, etc.) to suggest optimal service models and physical structures. Through this study, it aims to secure safer operations of urban railway as well as to improve better disaster responses through rapid and efficient spread of the situation in case of disaster.

In this study, among the W-S-R(Wiper-Signal-Rainfall) relationship methods used to produce sensor-based rain information in real time, we sought to produce actual rainfall information by applying machine learning techniques to account for the effects of wiper operation. To this end, we used the gradient descent and threshold map methods for pre-processing the cumulative value of the difference before and after wiper operation by utilizing four sensitive channels for optical sensors which collected rain sensor data produced by five rain conditions in indoor artificial rainfall experiments. These methods produced rainfall information by calculating the average value of the threshold according to the rainfall conditions and channels, creating a threshold map corresponding to the 4 (channel) × 5 (considering rainfall information) grid and applying Optima Rainfall Intensity among the big data processing techniques. To verify these proposed results, the application was evaluated by comparing rainfall observations.

This study compared the everyday-life information behaviors of urban and rural adolescents to suggest ways that school library information services can better meet the information needs of each of these groups. It focused its comparison not only on the everyday-life information-seeking behaviors but also on kinds of information grounds and barriers forming information grounds. Two qualitative methods, written activity logs and semi-structured in-depth interviews, were used to examine everyday-life information behaviors of adolescents. It is expected that the proposed strategies will be used in planning actual school library information services for urban or rural youths.

The development impact fee (DIF) zoning is used to adequately provide the pre-planned urban infrastructures in those urban and regional sectors where significant urban sprawl has already taken place followed by the rapid population growth. The infrastructure installation fees are levied to those landowners whose properties belong to the DIF zone in which they enjoy the direct benefits that accrue from the installed infrastructures. While the law is deemed to be equitable in that the actual beneficiaries pay for their benefits, it is required to designate the zone boundaries accurately and consistently since they are the very dividers that differentiate the legitimate fee-payers and the free-riders. This study, especially, tries to test a seemingly advanced alternative, so-called the cost-weighted distance measure, as a potential candidate to replace the current air-distance measures to designate the zone boundaries. The statistics indicate that the coefficient of variation for major indices spread from 11.75 to 35.6 in the case of the latter method, it only ranges from 0.21 to 0.76 in the case of the former. The zonal outcomes also show much higher consistency in their shapes. It is hoped, in this context, that the study findings could possibly be adopted in the future research efforts expected soon to amend and improve the current DIF zoning law.
