BACKGROUND Safety of evacuation is of paramount importance in disaster planning for elderly people; however, little effort has been made to investigate evacuation-related mortality risks. After the Fukushima Daiichi Nuclear Plant accident we conducted a retrospective cohort survival survey of elderly evacuees. METHODS A total of 715 residents admitted to five nursing homes in Minamisoma city,...

Emergencies, especially major ones, happen fast, randomly, as well as unpredictably, and generally will bring great harm to people's life and the economy. Therefore, governments and lots of professionals devote themselves to taking effective measures and providing optimal evacuation plans. This paper establishes two different emergency evacuation models on the basis of the maximum flow model (M...

This article reviews the literature describing four chemical and nuclear accidents and the lessons learned from each regarding the evacuation of civilian populations. Evacuation may save lives however, if poorly orchestrated, it may cause serious problems. For example, an inaccurate assessment of danger may lead to the evacuation of the same population twice, as the area requiring evacuation be...

| Planning and design of evacuation networks is both a complex and critically important optimization problem for a number of emergency situations. One particularly critical class of examples concerns the emergency evacuation of chemical plants, high-rise buildings, and naval vessels due to re, explosion or other emergencies. The problem is compounded because the solution must take into account ...

Hospital evacuation is a difficult process that requires a robust strategy and careful execution. In the past, threats leading to possible evacuation were primarily natural disasters. In recent years the broadened nature of threats, including hazardous material spills and terrorist incidents, has complicated this already complex problem. Its importance continues to grow, but there is still no c...

Emergent evacuation is particularly prominent in events of various disasters. However, most existing evacuation models are either missing some human behavioral characteristics in crowds, or are computationally complex. In the paper, a cellular automata (CA) model is proposed to verify validity of evacuation plan. In the model, route is defined by a series of sub-targets. A “distance map” concep...

We propose a static uncapacitated multi-commodity flow model along with a time-based scheduling tool for solving evacuation scheduling problems with capacity constraints. The paper addresses the problem of modeling evacuation scheduling out of an affected area, there are a pre-defined set of exit points out of the target affected area and a set of source points for the evacuees. The proposed ap...

BACKGROUND The goal of this study was to assess the impact of formal opt-out family planning training on clinical competence in uterine evacuation. STUDY DESIGN Residents who participated in newly established, routine opt-out family planning training completed surveys before and after their rotations. The surveys asked residents to report clinical experience and competence in family planning....
