International health insurance companie

国际健康保险公司为全球客户提供紧急医疗服务。在严重伤病情况下,通过合作的医疗撤离公司快速部署空运服务,通常2到3小时内即可到达患者所在位置。患者将被运送至最近的合适医疗机构,并在情况稳定后返回本国。

The goal of medical evacuation is to save a patient's life and/or limit the extent of an injury. If the patient's condition is stable and there is no risk from flying, the insurance company will have the patient flown to the nearest adequate medical facility. For example, if someone is injured in Cambodia they would be flown to Bangkok, if in West Africa, to France. Once the patient is stabilized, the insurance company may even have them flown back to their home country, if needed.

International health insurance companies provide insurance coverage for people all over the world. No insurance company is large enough to have their own fleet of planes available in every country. Instead, they have contracts with medical evacuation companies and planes worldwide. So in the case of a severe injury or illness, air transportation for the patient can be deployed very quickly. Depending on the physical location of the patient, extraction can be available often within 2 to 3 hours.

Many international insurance companies have divisions within their company that handle medical evacuation 24/7 for their clients. One of the companies that we work with has ten nurses and one medical officer (doctor) on staff in their evacuation division.

Here is the general procedure of a medical evacuation:

1. The insurance company is contacted concerning the need for a medical transportation.

2. The Medical Evacuation Division in the company makes a quick and complete evaluation of the illness or injury. This is generally done in consultation with a physician that works with the insurance company and medical personnel that are on the ground stabilizing the patient.

3. Evaluation of the physical and geographic location of the patient in regard to the nearest airport and nearest adequate medical facilities is considered.

4. The patient is evacuated to the nearest adequate medical facility, and once stabilized and if medically necessary, evacuated back to their home country.

5. If the medical condition is not overly serious they will use a common carrier for the evacuation often sending along medical personnel to assist the patient in flight. If the patient's condition is very serious, they will charter a plane from a medical evacuation company in the region.

成都市作为中国西部地区具有战略地位的核心都市,其人口的空间分布状况对于城市规划、社会经济发展及公共资源配置等研究具有基础性数据价值。本文聚焦于2019年度成都市人口分布的空间数据集,该数据以矢量格式存储,属于地理信息系统中常用的数据交换形式。以下将对数据集内容及其相关技术要点进行系统阐述。 Shapefile 是一种由 Esri 公司提出的开放型地理空间数据格式,用于记录点、线、面等几何要素。该格式通常由一组相互关联的文件构成,主要包括存储几何信息的 SHP 文件、记录属性信息的 DBF 文件、定义坐标系统的 PRJ 文件以及提供快速检索功能的 SHX 文件。 1. **DBF 文件**:该文件以 dBase 表格形式保存与各地理要素相关联的属性信息,例如各区域的人口统计数值、行政区划名称及编码等。这类表格结构便于在各类 GIS 平台中进行查询与编辑。 2. **PRJ 文件**:此文件明确了数据所采用的空间参考系统。本数据集基于 WGS84 地理坐标系,该坐标系在全球范围内广泛应用于定位与空间分析,有助于实现跨区域数据的准确整合。 3. **SHP 文件**:该文件存储成都市各区(县)的几何边界,以多边形要素表示。每个多边形均配有唯一标识符,可与属性表中的相应记录关联,实现空间数据与统计数据的联结。 4. **SHX 文件**:作为形状索引文件,它提升了在大型数据集中定位特定几何对象的效率,支持快速读取与显示。 基于上述数据,可开展以下几类空间分析: - **人口密度评估**:结合各区域面积与对应人口数,计算并比较人口密度,识别高密度与低密度区域。 - **空间集聚识别**:运用热点分析(如 Getis-Ord Gi* 统计)或聚类算法(如 DBSCAN),探测人口在空间上的聚集特征。 - **空间相关性检验**:通过莫兰指数等空间自相关方法,分析人口分布是否呈现显著的空间关联模式。 - **多要素叠加分析**:将人口分布数据与地形、交通网络、环境指标等其他地理图层进行叠加,探究自然与人文因素对人口布局的影响机制。 2019 年成都市人口空间数据集为深入解析城市人口格局、优化国土空间规划及完善公共服务体系提供了重要的数据基础。借助地理信息系统工具,可开展多尺度、多维度的定量分析,从而为城市管理与学术研究提供科学依据。 资源来源于网络分享,仅用于学习交流使用,请勿用于商业,如有侵权请联系我删除!
