Options of managing the stress situations during mass accidents
ŠEVČÍK, Radek
All of us face stress every day. The manner we are able to handle stress affects our behaviour, health and success in completing the tasks brought to us by our lives. The level of stress is immense in the mass accidents and the demands to handle such stress high. Therefore, it is beneficial to have certain awareness about the impact of stress; to know how stress affects us, what it make provoke in us and to know, as well, how to manage it efficiently. This kind of stress awareness should be very high mainly in the case of people who intervene at the very place of an accident tragedy. My bachelor thesis was prepared in the quantitative manner using questionnaires. The research sample was formed by selected employees of the accident flying squads of Salvage and Rescue Service (``SRS{\crqq}) of the South-Bohemian and South-Moravian regions. The main aim of my thesis was to determine whether there is a targeted preparation of the SRS employees for stress situations. I have set two hypotheses in respect of the research. Hypothesis No. 1, ``Employees of accident flying squads of the SRS practicing for more than 5 years are more informed on the stress issues during mass accidents{\crqq}, was confirmed. Hypothesis No. 2, ``Employees of accident flying squads of the SRS were trained specifically for stress situations during the mass accidents{\crqq}, was not confirmed. In my research, I found that 61.5% of the employees questioned did not pass any specific training for stress resistance. My bachelor thesis should serve as an impulse for the creation of a specific training for the employees of accident flying squads of the SRS and also as a potential ground to enhance the training in the given field within the study program of ``Health Rescuer{\crqq}.

Classification of electronic documents using cluster analysis
Ševčík, Radim ; Řezanková, Hana (advisor) ; Svátek, Vojtěch (referee)
The current age is characterised by unprecedented information growth, whether it is by amount or complexity. Most of it is available in digital form so we can analyze it using cluster analysis. We have tried to classify the documents from 20 Newsgroups collection in terms of their content only. The aim was to asses available clustering methods in a variety of applications. After the transformation into binary vector representation we performed several experiments and measured the values of entropy, purity and time of execution in application CLUTO. For a small number of clusters the best results offered the direct method (generally hierarchical method), but for more it was the repeated bisection (divisive). Agglomerative method proved not to be suitable. Using simulation we estimated the optimal number of clusters to be 10. For this solution we described in detail features of each cluster using repeated bisection method and i2 criterion function. In the future focus should be set on realisation of binary clustering with advantage of programming languages like Perl or C++. Results of this work might be of interest to web search engine developers and electronic catalogue administrators.

VZTAH INDEXU EKONOMICKÉ SVOBODY K INDEXU VNÍMÁNÍ KORUPCE
Ševčík, Radim ; Vrabec, Michal (advisor) ; Průša, Milan (referee)
The aim of this bachelor work is to estimate the dependency on corruption of economic freedom. Firstly, the theoretical backgrounds of both economical phenomena are examined. Then, the relationship between the economic freedom of the World Fraser Institute and the Corruption Perceptivity Index by Transparency International is discussed, using regression techniques and correlation analysis.
