Determining the Risk Level of Heavy Rain Damage by Region in South Korea

For risk assessment, two methods, quantitative risk assessment and qualitative risk assessment, are used. In this study, we identified the regional risk level for a disaster-prevention plan for an overall area at the national level using qualitative risk assessment. To overcome the limitations of previous studies, a heavy rain damage risk index (HDRI) was proposed by clarifying the framework and using the indicator selection principle. Using historical damage data, we also carried out hierarchical cluster analysis to identify the major damage types that were not considered in previous risk-assessment studies. The result of the risk-level analysis revealed that risk levels are relatively high in some cities in South Korea where heavy rain damage occurs frequently or is severe. Five causes of damage were derived from this study—A: landslides, B: river inundation, C: poor drainage in arable areas, D: rapid water velocity, and E: inundation in urban lowlands. Finally, a prevention project was proposed considering regional risk level and damage type in this study. Our results can be used when macroscopically planning mid- to long-term disaster prevention projects.

The model of community empowerment in fire forest disaster prevention in Indonesia

This paper will look into the topic of community involvement in forest fire disaster prevention, specifically in Indonesia. To begin, the paper will discuss the problem of forest fires in Indonesia, which occur frequently. The study also addressed issues related to disaster management, such as a lack of competence and knowledge, which resulted in disaster management ineffectiveness. The paper's third portion discusses the government's involvement in catastrophe management. Several initiatives and support have been implemented.

Joint Labor and Environmental Networks’ Chemical Disaster Prevention Recommendations to the U.S. Chemical Safety and Hazard Investigation Board

More than 180 preventable incidents at hazardous chemicals facilities occur each year, resulting in deaths, injuries, evacuations, shelter in place orders, environmental contamination, and facility shutdowns with permanent job loss. As of June 17, 2021, the Chemical Safety Board (CSB) had nineteen open site investigations of incidents that in total killed thirty-two people, injured at least eighty-seven people, led to thousands of residents sheltering in place or evacuating, and resulted in many millions of dollars in property damage. This document outlines twenty-one practical and measurable actions that the CSB can take to rebuild its investigative and recommendations capacity; set clear priorities for agency action; reform its governance policies; and increase public transparency and engagement. The proposed actions address incident investigations, safety studies, safety recommendations, agency governance, and public transparency and engagement.

Assessment of Prevention Performance Target Rainfall in Coastal Cities with Sea Level Rise

The rise in average sea level due to climate change aggravates the vulnerability of coastal areas, increasing the likelihood of flooding due to erosion of outfall to the coast and rivers. Therefore, the design standards of defense facilities should be strengthened to address such increased risk of flooding. Accordingly, in this study, a plan to adjust the disaster prevention performance target rainfall for two research areas was selected in consideration of the regional characteristics of the coastal area and the average sea level rise predicted for 2050, and the disaster prevention performance target rainfall increased from at least 89% to up to 169%. Based on these results, it is believed that this study can serve as a basis for improving data on rainfall targets for disaster prevention performance with consideration of future sea level rise in coastal cities.

Extreme value analysis of intracellular cargo transport by motor proteins

In the long axon of a neuron, cargo transport between the cell body and terminal synaptic region are mainly supported by the motor proteins kinesin and dynein, which are nano-sized drivers. Synaptic materials packed as cargos are anterogradely transported to the synaptic region by kinesin, whereas materials accumulated at the axon terminals are returned to the cell body by dynein. Extreme value analysis, typically used for disaster prevention in our society, was applied to analyze the velocity of kinesin and dynein nanosized drivers to disclose their physical properties in living cells.

Posttraumatic Growth after the Fukushima Nuclear Disaster: Examination of Free Descriptions among Fukushima Residents Who Lived in the Evacuation Area

We examined the differences in the posttraumatic growth (PTG) free descriptions from clusters of Fukushima residents (evacuation and non-evacuation zones) who experienced the Great East Japan Earthquake, and the relationship between “recovery from radiation anxiety” and the PTG-free description classification in these regions. A mail survey was conducted in August 2016 among Fukushima residents aged 20–79 years for free descriptions of their PTG. Participants were then divided into the “no anxiety,” “recovered from anxiety,” and “unrecovered from anxiety” groups based on their “recovery from radiation anxiety.” Data from 786 responses were analyzed. The PTG-free descriptions were classified into eight categories. Among those who lived in the evacuation zone versus those in the non-evacuation zone, “relating to others” (non-evacuation zone: 11.9% vs. evacuation zone: 18.4%) and “appreciation of life” (non-evacuation zone: 2.7% vs. evacuation zone: 9.8%) were significantly higher, and “increased awareness of disaster prevention” (non-evacuation zone: 20.4% vs. evacuation zone: 8.0%) was significantly lower. In the evacuation zone, “renewed recognition of nuclear issues” was significantly lower than the expected value in the no anxiety group (3.1%) and significantly higher than the expected value in the recovered group (22.9%). Further studies are needed to build support measures and potentially aid in preparing for future disasters.

Analysis On The Spatial Differentiation Characteristics of Poverty Risk Caused By Disaster Under The Stress of Geological Disasters – A Case Study of Sichuan Province

Research on the poverty risk caused by disasters in disaster - prone areas is a useful exploration to coordinate social economic development with disaster prevention and reduction, and is of great significance to regional sustainable development. Based on statistical data and spatial data, this paper takes Sichuan Province as the typical research area. Remote sensing and geographic information technology are used to study the poverty risk caused by disasters based on the quantitative evaluation of geological disasters risk and regional development level. the spatial differentiation characteristics of poverty risk caused by disasters are explored on the 1 km × 1 km grid scale. The results indicate that: (1) The overall risk of geological disasters in Sichuan Province is relatively high, with high and relatively high risk areas accounting for more than 40%, low and relatively low risk areas accounting for less than 30%. The risks in Mountain and Ravine Areas are significantly higher than other areas. (2) The regional development level in Sichuan Province is relatively high, but with significant the spatial differences. The development level of high-altitude areas and remote mountainous areas is quite different from that of the Chengdu Plain in the middle Sichuan Province. the problem of uneven development in the east, middle, and west is prominent. (3) The poverty risk caused by disasters is high, and the spatial pattern presents a characteristic of “high in the west and low in the east” with high positive spatial correlation. High - High Cluster Areas are mainly distributed in western and southwestern Sichuan. Low - Low Outlier Areas are mainly distributed in Chengdu Plain and Hilly Areas of Sichuan Basin. High - Low Outlier and Low - High Outlier Areas occupy a relatively small percentage with scattered distribution. This paper provides a reference for the coordinated management of disaster prevention and reduction, as well as social and economic development in underdeveloped areas.
