OBJECTIVE To describe the characteristics of patients who underwent a cranial operation and postoperatively suffered an intracranial hemorrhage significant enough to require evacuation. MATERIALS & METHODS : 3,109 cranial operations were performed at Houston Methodist Hospital (Texas Medical Center campus) between January 2009 and December 2013. Of these, 59 cases required a second operation fo...

Indoor emergency response plays a critically important role in disaster management for cities, which must consider the evacuation of people in a dynamic indoor environment. The spatial model is the foundation for the specific analysis of indoor emergency responses, such as evacuations. The current spatial model for evacuation has three primary pitfalls: (1) it primarily focuses on static spatia...

BACKGROUND Development of a postoperative hematoma is a reported complication after primary total knee arthroplasty. However, little is known about the clinical outcomes in patients who require surgical evacuation of an acute hematoma. The purpose of this study was to determine the incidence, risk factors, and long-term sequelae of postoperative hematomas requiring surgical evacuation. METHOD...

The statistics of sports arena accidents show that the main reasons which leading to crowd stampede are the exports blockage and the poor surrounding transportations. In the process of evacuation, the most common problem is that there are a large number of people are stranded and also they are the main carrier which leading to crowded stampede. With large amounts of data and reasonable evaluati...

The open government initiatives have provided tremendous data resources for the transportation system and emergency services in urban areas. This paper proposes a traffic simulation framework using high temporal resolution demographic data and real time open government data for evacuation planning and operation. A comparison study using real-world data in Seattle, Washington is conducted to eva...

OBJECTIVE To analyze and evaluate the efficacy of evacuation plans described by individuals with spinal cord injury (SCI). DESIGN Descriptive study from a convenience sample. SETTING Outpatient population center in Pittsburgh, PA, USA. METHODS Twenty-one individuals with SCI who previously indicated that they had a plan of evacuation from either their homes, places of work, or towns/citie...

For neurons, overexcitement is deadly. To avoid this, brain cells must sop up unneeded neurotransmitters from the synapse through membrane-bound transporters. If these transporters fail, neurons and other brain cells get excited to death—a phenomenon that may contribute to brain damage during stroke and Alzheimer's disease. Indeed, brain deterioration after stroke is associated with elevated le...

Walking speed is a very important factor in evacuation analysis for human safety. To provide against emergencies such as abandonment of ship due to accident, the authority body required evacuation analysis for passenger ships. To develop a simulation tool for the evacuation analysis, human behavior data for evacuation situations are fundamentally necessary. In this paper, onboard experiments we...

BACKGROUND Delayed epidural hematoma (DEH) following evacuation of traumatic acute subdural hematoma (ASDH) or acute epidural hematoma (EDH) is a rare but devastating complication, especially when it occurs sequentially in a single patient. CASE PRESENTATION A 19-year-old man who developed contralateral DEH following craniotomy for evacuation of a traumatic right-side ASDH and then developed ...

A simulation model based on temporal–spatial conflict and congestion for pedestrian–vehicle mixed evacuation has been investigated. Assuming certain spatial behaviors of individuals during emergency evacuation, a discrete particle swarm optimization with neighborhood learning factor algorithm has been proposed to solve this problem. The proposed algorithm introduces a neighborhood learning fact...
