Building a community that is resilient to disasters has become one of the main goals of disaster management. Communities that are more disaster resilient often experience less impact from the disaster and reduced recovery periods afterwards. This study develops a methodology for constructing a set of indicators measuring Community Disaster Resilience Index (CDRI) in terms of human, social, economic, environmental, and institutional factors. In this study, the degree of community resilience to na

This paper presents the performance of constructed bridges in cold regions through examining the bridges in North Dakota that is one of the coldest regions in the United States. Unique approach of a combined multiple regression and geographic information system technology is employed to evaluate the performance and to identify the critical sources affecting deterioration of the 5,289 bridges sampled from the National Bridge Inventory database inspected between 2006 and 2007. Typical parameters e

Due to continuing city growth and global warming over the past decades, urban heat island (UHI) effects, referring to the phenomena wherein the ambient air temperatures in cities are higher than those in rural areas, have become a serious threat to urban populations. Impervious surfaces, buildings with low-albedo materials, and a lack of vegetated areas are the major causes of poor urban thermal environments, particularly during the summer. Previous research has focused primarily on the thermal

Air quality is affected by the interplay between emission sources and urban planning factors such as land use, built environment, development pattern, and transportation. Few empirical studies have been conducted to determine the influence of urban form characteristics on air quality in Korea. Thus, the purpose of this research is to examine the relationship between urban form and air pollution, focusing on ozone pollution in Korea. The characteristics of urban form include density, concentratio

Socially and economically marginalized people and environmentally vulnerable areas are disproportionately affected by natural hazards. Identifying populations and places vulnerable to disasters is important for disaster management, and crucial for mitigating their economic consequences. From the fields of geography, emergency management, and urban planning, several approaches and methodologies have been used to identify significant vulnerability factors affecting the incidence and impact of disa

There has been increasing interest in effective evacuation in response to natural disasters, particularly in understanding human evacuation behavior. It is important to determine the factors affecting evacuation decision making to promote prompt evacuation. This study focuses on the effects of past experiences on evacuation behavior in South Korea, especially the evacuation drill experience. Additionally, the influence of demographic and socio-economic characteristics on evacuation behavior is c

Climate change is a growing problem and has been highlighted as a global issue. Empirical evidence increasingly indicates its obvious potential risks to humans and society. As members of this society, business organizations face greatly diverse climate change-related risks that they must recognize and respond to. However, gaps exist between scientific evidence and the actions of business organizations. Few empirical studies have examined the business organizations’ actions taken in response to c
