Assessment of electromobility possibilities in the South Bohemian Region
DUCHOŇOVÁ, Eva
This diploma paper evaluates the possibilities of the current state and development of electromobility in the South Bohemian Region in connection to other alternative ways of transport using the knowledge and resources for the development of elec-tromobility worldwide and in the Czech Republic. It further describes the usage in countries whose development affects the electromobility and predicts future devel-opment in the Czech Republic. The possibility of using subsidy titles and state sup-port of electromobility in the Czech Republic is compared to the evaluation of local specifications influencing this development - demands on the distribution system, engineering requirements in the form of partial demands of charging stations (port-folio, service, etc.). At the same time, barriers and support for this life trend are indicated, including the assessment of the pros and cons concerning electric cars in the Czech Republic and in the South Bohemian Region using SWOT analysis and Porter's model. At the end of the paper to support my hypothesis there are used the results of a questionnaire survey among business and non-business residents of the South Bohemian region.

Injury risks and their analysis in czech parkour community
Hubka, Petr ; Gryc, Tomáš (advisor) ; Bačáková, Radka (referee)
Title: Injury risks and their analysis in czech parkour community Objectives: The aim of this bachelor thesis was to find out when, where and how the most common injuries in parkour happen, which individual body segments are most affected and a comparison of injury rates between parkour competitors and non- competitors. Methods: The main methods used were analysis, synthesis and questionnaire survey. The subjects were parkour players aged 15 years and older. The questionnaire survey was used to obtain key information on injuries to recreational and elite parkour athletes. Results: 90% of parkour athletes have suffered at least one injury in the last 3 years of parkour training. The average number of injuries in 3 years of training is for competitive parkour athletes 3.03 and for non-competitive parkour athletes 2.77. The most common type of parkour injury is joint injury i.e. in 44% (n=57 responses). The most common skills that cause injuries in parkour are flips i.e. 36% (n= 40 responses) and jumps (precision, tictac, catleap and others) i.e. 32% (n= 36 responses). The most common place where parkour injuries occur is outdoors, i.e. at 57% (n= 66 responses). The most common body segment injured while doing parkour is the ankle joint (n= 50 responses). The most common cause of injury in parkour is...

Bird mortality at transparent barriers
Houdová, Monika ; Reif, Jiří (advisor) ; Koleček, Jaroslav (referee)
Bird mortality at transparent barriers (noise barriers or common house windows) is undoubtedly very important environmental issue, because of the rapid development of human society and even more rapid growth of very dangerous places for birds. At this time there is no review article yet, that would synthesize each sub-study on the extent to which individuals can die on those obstacles, which factors are critical for the ability of obstacle avoiding, how much collision threaten the vitality of bird populations and if we can prevent such unintended damage. This bachelor thesis handle with these questions as a literary review. From the available information we can suggests that the most important factor is migration behavior of birds, individuals migrating through the night are much more at risk than those migrating during the day, mostly because of light pollution, which can confuse them. The most dangerous time of year in this direction is clearly autumn, and that also relates with migration. Population losses caused by collision to the transparent barriers can be up to 20 % of the total population per year. Thesis in addition to a summary of available information on the issue proposes and evaluates possible preventive aplications, which may further serve to effective conservation for birds among...

Ecological and ethological aspects of bird-building collisions
Semeráková, Anna ; Sedláček, Ondřej (advisor) ; Koleček, Jaroslav (referee)
Collisions with artificial structures represent one of the most significant cause of bird mortality worldwide. Accounting for hundreds of millions bird deaths each year, bird-building collisions represent a particular problem. Although the bird's vision system is perfectly adapted to the orientation during fast flight, birds are often confused due to the transparency or reflectivity of the glass. Moreover, light pollution of urban areas interferes with the physiological geomagnetic and polarized light compass in birds, which causes the night migrants to disorient. The bird-building collision frequency variates in time and space. Throughout the day, largest number of fatal collisions occurs during early morning. Throughout the year, the peak in the numbers of fatal strikes appears in the course of autumn migration. Local species abundance did not appear to be the most important predictor of collision probability. Species traits making birds highly prone to collisions are small body size, high flight speed, long distance of migration and feeding strategy requiring rare and temporary food sources. Aggressive males during the mating period and inexperienced post-fledging juveniles are among the most vulnerable individuals. Based on taxon-specific ecological traits, some bird families were identified to...

Extreme obstacle racing
Simandl, Radek ; Hájková, Jana (advisor) ; Rotková, Hana (referee)
Extreme obstacle racing is a brand new sporting industry that is currently developing most not only in Europe but also around the world. I focused mainly on introducing this new sport in order to find out different level of the motor skills of beginners and professionals. In the theoretical part of my work, I defined what is characteristic for this sport and why it is so famous and wanted today. In the practical part, using the proposed test battery, I tested all the motor skills of beginners and professionals in order to identify the real physical differences between them. As a result of these facts, methods of testing, observation, processing, evaluation, analysis and statistics of data, along with the study of professional literature, were used. Based on the established hypotheses, I asked questions that I had in my opinions and attitudes to the beginners and professionals of this thriving sport. Through research and testing, we have found that professionals are certainly more dominant in motor skills than beginners with overall predominance in all underlying motor tests that included speed, endurance, strength and coordination tests. The benefit of this work is the analysis and introduction of a new sporting industry, including the main discovery of real differences between beginners and...

Vliv barvy překážky na kvalitu výkonu koně
HOLINKOVÁ, Petra
This diploma work deals with what influence the colour (red, yellow, green and blue) of an obstacle has on the jumping performance of horses. Eleven horses of different ages and breeds which are used for both recreational as well as sport riding purposes participated in the trial. The success of the horses at jumping over obstacles of variours colours was evaluated in relation to other selected variables, namely gender, age, height of the jump, and the type of riding surface. The horses were most successful at jumping yellow (96.4%) and red (95.2%) obstacles, whilst being less successful over green (85.7%) and blue (83.3%) ones. A successful jump included those where the front or hind hoof touched the obstacle without actually knocking the obstacle down. The values for touching the obstacle with the front or hind hoof were approximately the same for the red (7.1%) and green (9.5%) obstacles. With the yellow obstacles, there was a higher percentage of touching with the front hoof (11.9%) than the hind hoof (4.7%). With the blue obstacles, there was also a higher percentage of touching with the front hoof (10.7%) than the hind hoof (9.5%), although the difference was not as marked as with the yellow obstacles. The influence of the other selected variables on the jumping performance of the horses over the different coloured obstacles was diverse. The values of the correlation coefficients for gender and the type of riding surface did not prove there was a statistically significant influence of the horse´s success. In contrast, statistically significant relationships were proven for the height of a jump which was green, with a correlation coefficient rxy = -0.236+ (i.e. the higher the green jump the less successful the jumps), or yellow, with a correlation coefficient rxy = -0.377+++ (i.e. the older the horse the less successful the jumps).
