This study analyzed the impact of cooling shelters, a key heatwave response policy of local governments, on the reduction of heat-related patients, considering regional characteristics and overlapping vulnerable populations. Using pooled ordinary least squares, the impact was assessed based on data from 226 local governments nationwide from 2016 to 2022. The analysis showed that, unlike in metropolitan cities, cooling shelters had a negative effect on heat-related patients in Do (province) areas. In Si, Gun, and Gu (city, county, and district) areas, the effect varied depending on the type of overlapping vulnerable populations. While the reduction effect was greater in areas with higher elderly and elderly living alone populations, it was not statistically significant in Gun (county) areas and showed a decreasing trend for elderly basic livelihood security beneficiaries in large city districts. These results suggest the need for a customized strategy that reflects regional and vulnerable group-specific characteristics, moving beyond a uniform policy application. This study provides academic and policy contributions by offering such evidence.

This study examines the structural effects of increasingly frequent natural disasters on South Korea’s housing market. Using nationwide apartment transaction data and disaster damage records from 2022 to 2023, it empirically investigates how natural hazards influence housing price inequality and spatial segregation. The findings indicate that areas with greater disaster damage tend to experience lower apartment prices, accompanied by widening price disparities and increased inequality. However, the impact of disasters on spatial segregation was not statistically significant. These results suggest that natural disasters can deepen regional disparities and housing inequality beyond short-term price shifts. By providing a multi-layered, national-level quantitative analysis, this study offers policy insights for addressing structural inequality and strengthening the resilience of housing policies in disaster contexts.

This study empirically analyzes the impact of major natural disasters on the sale prices of single-family houses. Employing 2023 transaction data from the public real estate transaction system of the Ministry of Land, Infrastructure, and Transport, a hedonic regression analysis was conducted to assess the relationship between disaster experience and housing prices. The results reveal that single-family house prices in disaster-affected areas were, on average, 12.8% lower than those in non-affected areas, with the decline being more significant in areas that experienced repeated disasters. Specifically, house prices in areas with two disaster experiences declined by an average of 18.7%, and recovery took longer. Additionally, price fluctuations varied by disaster, housing type, and the local housing market. This study provides empirical evidence regarding the impact of natural disasters on the sale prices of single-family houses and underscores the necessity for real estate market stabilization and housing recovery policies in disaster-prone areas.

In Busan Metropolitan City, Bus Rapid Transit (BRT) has been installed as a public transportation initiative aimed at improving the punctuality and speed of buses. While BRT installation improved the speed of buses, the speed of general vehicles decreased. This reduction in the general vehicle speed also affects the timely dispatch of firefighting vehicles. Therefore, this study investigated the effects of the BRT installation and the specific sections of the BRT installation in Busan on the dispatch speed of firefighting vehicles. The analysis used data from the dispatches of 119 safety centers belonging to Busanjin Fire Station to Busanjin-gu from 2013 to 2022. A multiple regression analysis was conducted by dividing the collected data into two categories: BRT installation dates and sections along Jungang-daero, Chungryeol-daero, Haeundae-ro, and Gudeok-ro, where BRT was installed. The results of the analysis revealed that the BRT installation and linkage system in Busan Metropolitan City positively influenced the dispatch speed of firefighting vehicles, improving it by approximately 18%, from 16.26 km/h to 3.03 km/h. This improvement is likely attributed to the dedicated bus-only lanes, which allow firefighting vehicles to operate in a flow separate from the stagnant general traffic, leading to faster response times.

This study analyzes the major factors affecting the installation of residential firefighting systems in detached houses. In particular, it investigates the dependence of local fire risk and local government prevention efforts, along with housing and household characteristics, on the type of installation. This study used data from the 2020 Population and Housing Census, the first nationwide survey on residential firefighter system installation, and employed multinomial logistic regression analysis. The analysis results revealed that less than half of households had installed all firefighting systems, where the installation rate differed significantly by region. Housing and household characteristics also influenced the installation type. Local fire risk as well as the local government’s fire prevention policies positively affect the installation of residential firefighting systems.

This study aims to empirically verify whether disasters affect physical changes, linking research on the effects of disasters on psychology and the effects of psychology on physical changes. It focused on the Sewol ferry disaster, and physical changes were tracked from 2010 to 2018, including the four years before and after the disaster in 2014. We constructed panel data on obesity rates from 229 local governments and used longitudinal data to analyze the impact of large disasters on changes in obesity rates over time. The results indicated that the Sewol Ferry Disaster had a long-term effect on the increase in obesity rate over time. In the directly affected areas of Ansan and Jindo, there was not only a long-term increase but also an immediate increase in the obesity rate. The findings of this study provide an opportunity to expand our understanding of the impact of disasters on society, and can also serve as foundational data for national and local disaster-related long-term impact support policies.

This study empirically analyzes the impact of local governments' disaster preparedness capabilities and local characteristics on storm and flood damage. It considers the budget allocated by local governments for securing and managing disaster management resources as a disaster preparedness capability. Impervious area is used as a local characteristic. Disaster management resources are significant because they are built and utilized during preparedness, response, and recovery phases. Local characteristics should also be considered because of their influence on the impact of disasters. The results of this study indicate that the ratio of the disaster management resource budget affects the reduction of damage. The impact of the budget increases in areas with a relatively higher percentage of impervious area. Therefore, local governments must secure and manage disaster management resources as part of their disaster preparedness. This can be achieved by utilizing ordinances and plans.
