There have been various studies analyzing public sentiment after a large-scale disaster. However, few studies have focused on the relationship between public sentiment on social media and its results on people’s activities in the real world. In this paper, we conduct a long-term sentiment analysis after the Great East Japan Earthquake and Tsunami of 2011 using Facebook Pages with the aim of inv...

background: environment and its ecosystems are affected by various natural and man-made disasters. the environmental management in disasters tries to protect ecosystems, sustain development, reduce disaster risk, and adapt to or decrease the impact of climate change. this study aimed to investigate the impact of disasters on the environment and methods of reducing these effects. materials and m...

The field of crisis management knowledge and expertise is associated with a wide range of fields. Knowledge-based crisis management is a combination of science, art and practice. Iran is an earthquake-prone country. Through years several earthquakes have happened in the country resulting in many human and financial losses. According to scientific standards, the first 24 hours following an earth...

INTRODUCTION In order to prepare the healthcare system and healthcare personnel to meet the health needs of populations affected by disasters, educational programs have been developed by numerous academic institutions, hospitals, professional organizations, governments, and non-government organizations.

This paper presents a method for determining the network lines and buses where the occurrence of faults will lead to voltage sags causing severe financial losses in the power system. The proposed method is based on a typical stochastic assessment of voltage sags. The network regions where fault occurrences will simultaneously lead to voltage sags at different sensitive load points can be determ...
