We propose a stochastic optimization approach for the location and distribution problem of medical supplies to be used in disaster situations. We develop a robust decision support mechanism, which is serviceable under the wide variety of possible disaster types and magnitudes. In preparation for disasters, we develop a stochastic programming model to select the storage locations of medical supp...

This research investigates the public's trust in risk-managing organizations after suffering serious damage from a major disaster. It is natural for public trust to decrease in organizations responsible for mitigating the damage. However, what about trust in organizations that address hazards not directly related to the disaster? Based on the results of surveys conducted by a national institute...

BACKGROUND Few studies have examined the contribution of specific disaster-related experiences to post-traumatic stress disorder (PTSD) symptoms. AIMS To examine the roles of peri-traumatic stress and distress due to lingering disaster-related disruption in explaining linkages between disaster exposure and PTSD symptoms among a cohort exposed to the 2010-2011 Canterbury (New Zealand) earthqua...

No previous study has been able to examine the association by taking account of risk factors for dementia before and after the disaster. We prospectively examined whether experiences of a disaster were associated with cognitive decline in the aftermath of the 2011 Great East Japan Earthquake and Tsunami. The baseline for our natural experiment was established in a survey of older community-dwel...

BACKGROUND Health professionals involved in a disaster are not immune to the stressors. However, little attention is given on the psychological consequences among these professionals. This study has explored the frequency of posttraumatic stress disorder (PTSD) among them after the Nepal earthquake 2015. METHODS A descriptive cross sectional study was carried out amongst the medical professio...

When stricken by a catastrophic natural disaster, the efficiency of disaster response operation is very critical to life saving. However, communication systems, including cellular networks, were usually crashed due to various causes making the coordination among a large number of disorganized disaster response workers extremely difficult. Unfortunately, rapid deployment of an emergency communic...

On September 21, 1999 the 921 or Chi Chi earthquake struck the centre of Taiwan. The earthquake’s magnitude was ML 7.3, and MW 7.7 and the epicentre depth was 8 km. The earthquake hit at 1:47 am, and left about 2,471 dead and 11,305 seriously injured. Over 10,000 buildings collapsed and direct losses were estimated at US$14 billion. This paper describes some of our preliminary findings on a Nat...

BACKGROUND Physical inactivity is a health issue that often occurs after serious disaster. Social factors, which can be disrupted by disaster, are important determinants of physical activity levels in everyday living. This study was designed to confirm the association between social factors and physical activity among elderly survivors of the Great East Japan Earthquake. METHODS From Septembe...

Mental health is an important aspect of public health after a disaster. This article describes what is known and what remains to be learned regarding the mental health impact of the January 12, 2010, earthquake in Haiti. Public health surveillance efforts in Haiti and the United States in the first 2 months after the earthquake are described. Challenges in clinical assessment and public health ...

The devastating Haiti earthquake rightly resulted in an outpouring of international aid. Relief teams can be of tremendous value during disasters due to natural hazards. Although nobly motivated to help, all emergency interventions have unintended consequences. In the immediate aftermath of the earthquake, many selfless individuals committed to help, but was this really all in the name of reach...
