研究目的:探讨不同草坪下不同鞋钉构造对足球运动员进行特征动作的下肢生物力学表现和非接触性运动损伤风险。研究方法:选取14名专业男性足球运动员作为受试者,受试者分别着长钉足球鞋(Soft Ground Design,SG)、短钉足球鞋(Artificial Ground Design,AG)和碎钉足球鞋(Turf Cleats,TF)在自然草皮(Natural Turf,NT)和人工草皮(Artificial Turf,AT)条件下进行直线加速跑和45°左侧切动作。vicon三维红外运动分析系统用于采集下肢运动学数据、Kistler三维测力台同步收集地面反作用力数据。研究结果:直线加速跑和45°侧切动作中,AT-SG的膝关节峰值屈曲角度和屈曲活动度均显著大于NT-TF和AT-TF;NT-SG和AT-SG的地面反作用力垂直负荷加载率(vALR)显著高于NT-TF和AT-TF,鞋钉和草皮交互作用显著。45°侧切动作中,AT-SG和NT-TF的平均抓地系数值最小,鞋钉和草皮交互作用显著。研究结论:长钉SG足球鞋在AT较大的膝关节屈曲角度和屈曲活动度有利于缓冲较大的地面冲击力,但容易引起长时间运动疲劳程度加快,导致非接触性运动损伤风险的增加。同时,长钉SG足球鞋在AT上较高的vALR容易引起如胫骨疲劳性骨折、跟腱炎等损伤风险的增加。

足部作为人体动力链与外界环境接触的始端,形态的变化与功能的表现紧密相关。通过对即刻与短期裸足运动干预以及长期裸足运动人群的足部形态和运动学、动力学、肌肉活动度等生物力学特征进行系统总结归纳,旨在从生物力学角度揭示裸足运动的本质特征,探究形态与功能的关联。研究发现,习惯着鞋人群在短期裸足步行及跑步运动干预时,均表现出小步长、高步频的时空参数特征。短期裸足步行及跑步后足触地角度减小,踝关节跖屈增大,膝关节屈曲程度增大等运动学特征与习惯裸足人群的运动学特征相似。对习惯着鞋人群进行短期裸足步行及跑步干预时,比习惯裸足人群在着地期的冲击峰值及垂直负荷增长率均呈现降低。长期使用不合脚鞋具可改变足形和功能,如足部肌群横截面积减小,足前掌宽度及接触面积降低,拇指外翻及削弱绞盘功能等。被抑制的足部功能或许是习惯着鞋人群损伤风险较大的原因,而开展裸足运动时需综合考量足形态与功能,循序渐进,以实现足部功能训练,提高运动表现。

以降低高跟鞋损伤风险为出发点,对高跟鞋步态生物力学特征进行系统综述,并结合相关流行病学依据对高跟鞋引发的肌肉骨骼系统损伤情况作出总结,为进一步研究提供思路.对高跟鞋步态中足底压力分布、下肢各关节三维角度变化及关节力矩特征三方面进行了较为全面的总结与分析,并且明确阐述了高跟鞋对踝关节扭伤、足部疼痛及摔倒的生物力学机制的影响.但到目前为止,没有足够的流行病学研究证据可以证明高跟鞋会增加膝关节炎的患病风险.随着对高跟鞋步态及其损伤机制更为明确与深入的认识,高跟鞋设计也将朝着更加人性化与合理化的方向发展.

Industrial accidents have shown that many people can be affected,such as in Seveso,Italy,in 1976.Industrial accidents in nuclear power plants have also led to fatalities and evacuations.To better guide preparedness against and mitigation of industrial accidents,an assessment is necessary to evaluate hazard exposure and the type of potentially vulnerable social groups that need to be taken into account.This study conducted a spatial assessment of three types of industrial facilities in Germany:facilities registered under the Seveso Directive,chemical parks,and nuclear power plants.The method consisted of a spatial assessment using a Geographic Information System of exposure around hazardous sites registered under the S eveso Directive in Germany and of census data to analyze social vulnerability.Hazards analyzed included industrial accidents and earthquakes.The results revealed that most industrial sites are in urban areas and that population density,the numbers of foreigners,and smaller housing unit sizes are higher in close proximity to these sites.The buffer zones analyzed in circles between 1 and 40 km show a decreasing vulnerability with more distance.This can guide emergency management planners and other stakeholders to better prepare for major accidents and better devise disaster risk reduction strategies specifically for different social groups.

Aggressive behavior in patients with psychiatric disorders is attracting increasing research interest.One reason for this is that psychiatric patients are generally considered more likely to be aggressive,which raises a related question of whether diagnoses of psychiatric disorders predict the prevalence of aggressive behavior.Predicting aggression in psychiatric wards is crucial,because aggressive behavior not only endangers the safety of both patients and staff,but it also extends the hospitalization times.Predictions of aggressive behavior also need careful attention to ensure effective treatment planning.This literature review explores the relationship between aggressive behavior and psychiatric disorders and syndromes(dementia,psychoactive substance use,acute psychotic disorder,schizophrenia,bipolar affective disorder,major depressive disorder,obsessivecompulsive disorder,personality disorders and intellectual disability).The prevalence of aggressive behavior and its underlying risk factors,such as sex,age,comorbid psychiatric disorders,socioeconomic status,and history of aggressive behavior are discussed as these are the components that mostly contribute to the increased risk of aggressive behavior.Measurement tools commonly used to predict and detect aggressive behavior and to differentiate between different forms of aggressive behavior in both research and clinical practice are also reviewed.Successful aggression prevention programs can be developed based on the current findings of the correlates of aggressive behavior in psychiatric patients.

While social vulnerability assessments(SvA)use spatial indicators and indices that have become state of the art, they also receive substantial critique. This article analyzes, by means of a literature review of 63 articles, if and in which aspects such an indicator approach is regarded as useful by scientific studies. The findings indicate a need for more research on the validation and justification of indicators. This article supports the conceptual development of SvA by adding to reflection about advancements and applications, but also shortcomings. The main advancement area discussed is validation and the demand for establishing benchmark criteria for vulnerability. Based on this, longitudinal monitoring of vulnerability and validation studies are conceivable based on existing SvA, but these efforts demand more conceptual development.

Society is reliant on infrastructure services, such as information and communication technology, energy, water, and food supply, but also on governmental, cultural, and search and rescue organizations. The goal of project KritisKAT at the Federal Office of Civil Protection and Disaster Assistance in Germany is the development of generic criteria for the identification and evaluation of infrastructures regarded as “critical” for society. Acknowledging that full protection against all threats and cascading effects is not possible, the approach focuses on the impacts rather than the prevention of threats. The development of generic criteria requires the prioritization of infrastructures and identification of their key characteristics for civil protection purposes, risk management activities, and strategic proactive planning. For this purpose, the development of a national critical infrastructure priority inventory is based on a thorough examination of the range of criteria typically used in similar approaches. The specific focus of this paper is to identify and simplify essential characteristics of infrastructure criticality. The main outcome of this study is the development of common criteria generally applicable to a variety of infrastructures.
