of the dissertaton Title: The use of biomechanics as a supportng argumentaton for the conclusions of expert opinions Auhtor: Ing. Vratslav Veselý, MBA Keywords: trafc accident, mechanism of injury, head injury, pedestrian, car windscreen, head impact velocity, deformaton zones The aim of this dissertaton is to map the mechanical propertes of the bones of the face and skull from the available literature and to describe the mechanisms of brain and cervical spine injuries. The descripton of these mechanisms contributes to the elucidaton of the origin of injuries from a purely mechanical/biomechanical perspectve, and in forensic practce contributes to the understanding of the situaton by other engineering professions not involved in forensic medicine. The strength and stfness parameters of the bones of the face and skull are used to determine the magnitude, directon and locaton of possible forces for fracture formaton, etc. Another objectve is to propose and describe a simple analytcal approach for determining the velocity of the head when striking the windshield of an automobile. To address the dependence of head impact velocity and car speed, and the efect of windscreen tlt. Using experimental testng, to describe the defects produced on the windscreen of a car afer a crash of...

Mechanics and consequences of impact head load
Plešková, Kristína ; Jelen, Karel (advisor) ; Tlapáková, Eva (referee)
Title: Mechanics and consequences of the head load impact. Objectives: The objective of the main part of the diploma thesis is the analysis of the data obtained during crash-test experiments, using a tram and a Hybrid III test dummy. The aim of the analysis is to describe the effect of mechanical load on the human head during collisions at different tram velocities, the position of the dummy and the types of front bodies of tram sets. Method: The work has the character of experimental research based on the results of a crash test and confirmation or refutation of hypotheses. Four types of tram sets used in Prague (T3, KT8D5, T14, T15) and a Hybrid III crash test dummy were used for the research. Based on the selected criteria, a contact impact of the tram into the dummy was performed and individual components of the acceleration vector were recorded. Obtained data were processed in Microsoft Office Excel 2007 and magnitude of the acceleration vector was calculated Head impact criterion (HIC) and Abbreviated injury scale (AIS) were used for assessment of the impact and porbability of severe head injury. The experiment took place on the tram track in the central workshops of DPP, in cooperation with UK FTVS, VUKV a.s., ŠKODA Transportation, Advance Engeneering and. No need for the approval of the...

The Level of Child Injury Prevention
Veselá, Marika ; Eislerová, Iva (advisor) ; Houšťková, Hana (referee)
The aim of my thesis titled "Level of child injury prevention" is to highlight the issue of child injuries and compare the results of two types of primary schools - urban and rural. This area is often underestimated, although it concerns a substantial part of our population. The work is divided into a theoretical and a practical part. The theoretical part focuses on prevention and its distribution, and the epidemiology of injuries and first aid, which plays a very important role. The empirical part consists of quantitative research based on a questionnaire survey, which focused on pupils at 9 th classes (which means children at the age of 14 and 15). It describes also the methodology of the research and its organization. Based on the information gathered in this section. The results are compiled, evaluated and recorded in tables and graphs with the follow up discussion. Key words: prevention, child injuries, head injury, musculoskeletal injury, first aid

Head injury at fatal road accidents.
AMBRŮŽEK, Tomáš
The issue of road accidents rate has been generally and continually a topical issue not only in the Czech Republic but in the whole developed world. This is the reason why this bachelor thesis deals with traffic accidents, more specifically with head injuries in fatal road accidents. The goal of this work was to asses the percentage presented by head injuries in fatal consequences of road accidents and identify the most common causes of death in car accidents. With the view of the set goal, the following hypothesis was formulated: ``Head injuries are the most frequent cause of death in traffic accidents.{\crqq} During the research, I used the methods of secondary and content analyses to review and asses head injuries in fatal traffic accidents. The analyzed sample was presented by 91 people killed in traffic accidents dissected at the Forensic Department of the České Budějovice Hospital. The data were collected from their autopsy reports. The method of combined analyses was used to identify and classify the type of their fatal injuries, i.e. whether the cause of death was the head injury itself, whether there were polytraumas with a fatal head injury combined or if the death was caused by other injuries. The research has fulfilled the original goal of this work {--} to asses the percentage presented by head injuries in fatal consequences of road accidents and identify the most common causes of death in traffic accidents. Drawing on the results of the research it is possible to state that the hypothesis (Head injuries are the most frequent cause of death n traffic accidents.) has been verified.
