Possibilities of kinesio taping to prevent injuries of professional dancers

A literature review of the application of kinesio taping in the prevention of professional dancers’ injuries indicated frequent dance-related and overuse injuries and a lack of organized information about this issue. This study aimed to assess the impact of kinesio taping on the musculoskeletal system of dancers, based on scientific research data from 2015–2017. The analysis revealed that kinesio taping can effectively reduce muscle spasms, rebuild muscle strength of the injured extremity, improve static and dynamic balance and ease pain, due to its ability to improve proprioception of joints and regulate muscle tone. These effects reduce muscle imbalance and joint instability, thus increasing treatment efficacy and shortening the physical load limitation. Kinesio taping significantly reduces the risk of overuse syndromes and dance-related injuries during dance training and strenuous exercises of people with chronic musculoskeletal diseases. Therefore, kinesio taping has broad utility in primary and secondary prevention of dance-related injuries.     

Trauma demography and clinical epidemiology of motorcycle crash–related head injury in a neurosurgery practice in an African developing country

Objective: Though motor vehicle crashes (MVCs) were the main cause of head trauma from road traffic injuries (RTIs), motorcycle crashes (MCCs) are now a major cause of RTI-related head injury (HI) in many developing countries.

Methods: Using a prospective database of HIs from a neurosurgical practice in a sub-Saharan African developing country, a cross-sectional survey was conducted for the trauma demography and clinical epidemiology of this MCC-related HI.

Results: Motorcycle crashes accounted for 57% (473/833) of all RTI-related HIs in this registry. The victims, with a mean age of 33.1 years (SD = 18.3), consisted mainly of males (83.1%), those of low socioeconomic status (>90%), and those aged between 20 and 40 years old (56%). MCCs involved only riders in 114 cases (114/473, 32.1%), of which 69% were motorcycle–motorcycle crashes. The HI was moderate–severe in 50.8%; clinical symptomatology of significant HI included loss of consciousness (92%), anisocoria (35%), Abbreviated Injury Scale head (AIS–head) score > 3 (28%), and CT-Rotterdam score > 3 (30%). Extracranial systemic injury involved the limbs most frequently, with an Injury Severity Score (ISS) >25 in 49%. The fatality rate was 24%.

MCC-related HI among pedestrian victims involved more vulnerable age groups (the young and elderly) but have lower mean ISS compared to motorcycle passengers (mean ISS = 23.5 [11.6] vs. 27.4 [13.0]; 95% confidence interval [CI], 1.27–6.49; P = .004). In addition, compared to a contemporary cohort of MVC-related HIs in our registry, MCC victims were older (mean age 34.8 years [18.0] vs. 30.8 [18.4]; P = .002); had higher proportions of certain extracranial trauma like long bone fractures (71 vs. 29%; P = .02); and suffered fewer surgical brain lesions (25.5 vs. 17.2%; P = .004).

Conclusions: Motorcycle crashes are now a significant threat to the heads, limbs, and lives of vulnerable road users in developing countries.     

重庆市突发环境事件时空格局及影响研究

基于2009年-2015年重庆市突发环境事件统计数据,研究了重庆市近7年突发环境事件的动态变化趋势、空间分布格局及污染影响特征,讨论了引发突发环境事件内外部因素之间的关系.结果表明:重庆市7年内共发生突发环境事件134起,且呈波动下降趋势,春季和夏季为交通事故和自然灾害高发期;突发环境事件空间上主要集中在主城九区及相邻的区县,渝西、渝东南及渝东北各区县发生次数较少.道路交通事故、设备故障和操作不当是导致突发环境事件的主要因素,主要发生形式为泄漏.污染类型主要为水污染和水气复合污染,污染物出现频率大小为:油类>酸碱类>液氨>苯及其化合物>减水剂>其他各种污染物.

溢油鉴别数字化判定在船舶油污事故调查中的应用

本文以一起船舶油污事故的溢油源调查为例,简述了重复性限法、t检验法两种方法的判定原则及判定流程,具体介绍了两种方法在船舶油污事故溢油源鉴定中的应用。应用结果表明,重复性限法、t检验法是两种值得在船舶溢油事故鉴定中推广应用的判别方法,诊断比值的准确性是影响两种判定方法应用的一个重要因素。     

生产安全事故责任认定定量化方法的探讨

当前,我国生产安全事故的责任认定是在事故调查组分析调查事故原因后,对事故责任者承担的责任进行定性的责任认定,受一定的主观因素影响。为了避免主观因素的影响,本文提出了一种责任认定定量化方法,该方法首先从安全管理、安全技术和职业健康卫生三方面建立了完善的事故影响因素集;然后在分析事故原因后采用专家打分法(德尔菲法)确定各影响因素的影响度,并计算出与事故相关的责任者的累加影响度,即责任大小;最后根据事故造成的人员伤亡和经济损失情况对事故责任者作出处理。此方法对生产安全事故责任认定更加公正客观。

为了研究我国煤矿各类事故之间的相互关系,运用主成分分析法对我国煤矿事故数据进行了统计分析,计算得到煤矿事故类型的第一主成分和第二主成分,并进一步分析了煤矿事故的主要类型以及各类事故之间的相互联系,对制定相应的煤矿事故预防措施具有一定的指导作用。     

中国突发环境事件时间序列分析

突发性环境事件时间序列特征可表征环境风险管理成效及存在问题。研究表明2000年以来中国突发环境事件预防、控制与管理取得了显著成效,其中,突发性水污染事件、大气污染事件以及噪声振动危害年发生频次呈大幅度降低趋势,但固废污染事件自2003年以来的年发生频次变化不大,而其它突发性环境事件自2002年以来的年发生频次则呈快速增长态势,说明中国在强调突发性水环境和大气环境事件监管的同时,还需加强固废污染事件及其它类型突发环境事件的监控与管理。     

基于人体皮肤热模型的热防护服评价方法研究

在热防护服热防护性能测试装置基础上,用自行研制的新型耐高温模拟皮肤传感器代替铜片热流计测量通过应急热防护服装面料的热流量,将热流量作为热波皮肤模型边界条件,得到人体皮肤表层下80μm处的温度值,从而得到一定条件下人体真实皮肤达到二级烧伤所需时间,用其评价热防护服用织物的热防护性能,并将热波皮肤模型(TWMBT)的测试值与Pennes模型以及铜片热流计的测试结果进行分析比较。采用热波皮肤模型分析织物层下的"皮肤"防热时间更接近实际皮肤达到二级烧伤时间值,可较为精确的量化织物热防护性能,为应急救援热防护服装的热设计提供理论依据。     

Pedestrian fatalities, Atlanta Metropolitan Statistical Area and United States, 2000-2004

Motor vehicle crashes killed almost 5,000 pedestrians in 2005 in the United States. Pedestrian risk may be higher in areas characterized by urban sprawl. From 2000 to 2004, pedestrian fatality rates declined in the United States, but the Atlanta metropolitan statistical area did not experience the same decline. Pedestrian fatality rates for males, Hispanics, and the 15–34 and 35–54 year age groups were higher in Atlanta than in the United States overall. Pedestrian safety interventions should be targeted to high-risk populations and localized pedestrian settings.
