The perception of crisis communication via social networks by subculture of university students
Kroupa, Pavel ; Opatrný, Martin (advisor) ; Černík, Roman (referee)
The subject of my thesis is perception of crisis communication through social network. The aim of this work is to verify the connection and context between social network, interpretation and risk evaluation. The first theoretical part deals on the research of appropriate literature and defines key words like perception of information, communication, crisis communication, social medias and social networks. It also analyses the structure and communication process, types of communication, theoretical models of crisis communication, instruments of crisis communication and social networks themselves such as Twitter and Facebook. The theoretical part is the basis of the empirical part, which describes the realization of the research among college students. Stated hypotheses lead to the formulation of research questions and build the questionnaire. The questions in the questionnaire are built to verify that the high number of shared posts, sharing a particular user or a large number of controversial comments to that contribution may be related to the interpretation and evaluation of the crisis. It is emerging from the research that the high amount of sharing a post and the concrete person who shares this post has influence on the interpretation and evaluation of the risk. Benefit of this work is the fact that...

Treating extraordinary situations connected with the leakage of dangerous harmful substances applied in the Brewery Eggenberg, a. s.
FUČÍK, Jaromír
The thesis treats the situation connected with the possible leakage of ammonia, applied in the Eggenberg a. s. brewery as cooling medium. It deals with the so-called worst variant of the accident {--} leakage of the maximum possible amount of the substance. The introduction is devoted to the legislation concerning the dangerous chemical substance, prevention of serious accidents, components of the integrated rescue system and the fire prevention. The thesis contains the characteristics and the description of ammonia as dangerous substance, with focus on its toxicity and it analyses the results of a possible leakage. For the simulation of a possible accident, the software instrument TerEx was applied. The calculations acquired after entering the input data into the program served for determination of the zone where the detrimental concentration of ammonia would reach in case of a leakage. In comparison with the original calculations performed in the last years applying the ROZEX programme, the zone with a harmful concentration would be substantially extended. The results of the thesis should be taken into consideration in the emergency plan of the region and in the emergency plan of the Eggenberg a. s., Brewery, however, also the procedure of the intervention of the integrated rescue system components shall be specified. Moreover the way of performing the inspections in the section of the fire protection in subjects applying, processing or storing dangerous chemical substances and preparations is drafted. The thesis tries to draw the attention to the fact that also a relatively small amount of a dangerous chemical substance may cause a considerably significant accident.
