The models to predict when and where a landslide occurs were constructed with different purposes and scopes, but tended to be complementary to each other. The objective of this study was to convert the static landslide hazard into the dynamic landslide hazard and combine a spatiotemporal hazard matrix to assess it, in order to enhance the usability of the early warning system for landslide and the landslide hazard map developed by the Korea Forest Service. We applied various matrix evaluation models to develop scenarios and assess the 2017 landslide occurred in Cheonan, Korea. The results of this study showed that a simple combination of matrices facilitated quantitative evaluation of the dynamic landslide hazard and its accuracy was higher than the static landslide hazard map. In addition, the dynamic landslide hazard can be assessed for the near future by integrating the 1-hour prediction data provided by the Korea Forest Service. The results of this study can help maximize the utilization of the existing national landslide forecast system and landslide hazard map, which should enhance the efficiency of managing landslide-prone zones during the rainy season.

This study aims to analyze the characteristics of emergency medical services (EMS) utilization among elderly patients divided into two groups depending on place of living: nursing homes and places other than nursing homes. The data includes patients aged 65 years old and over for whom ambulances were requested by the 119 Dispatch Center in Gyeonggi Province from January 1st to December 31st, 2018. Statistical analysis was performed using IBM SPSS Statistics 21.0. The findings showed that EMS ambulances were requested more frequently for female patients in nursing homes than males in other places. Brain disease was the most common medical history of the EMS users at nursing homes (P=0.000). Also, critical medical conditions, such as cardiac arrest (5.4%), altered mental status (16.4%), difficulty breathing (18.6%), and fever (19.2%), were found more than twofold higher among the EMS patients in nursing homes, which were classified as emergency by EMS crews. This study suggests a review and amendment of the legal standards regarding support for emergency medical providers and allocation of ambulances.

With an aim to reduce the damage to the elderly who are vulnerable to disasters, this study analyzed the impact of disaster information access and understanding on the elderly’s response actions in disaster situations. The data were collected by surveying 191 elderly people over 65 years old living in their homes in Busan Metropolitan City. The analysis was conducted by frequency analysis and descriptive statistics using the SPSS 22.0 program to identify the demographic characteristics and major variables of the subjects. A multiple regression analysis was also conducted to verify whether information access and understanding of the elderly affects their disaster response behavior. It is found that the elderly’s disaster response behavior is affected by their access to disaster information on human resources (β=.205) and their understanding of disaster information on material resources (β=.340). The results of this study suggested the implementation plan to improve the disaster coping capacity of the elderly.
