Krátký, Štěpán ; Bělka, Miloslav (referee) ; Lízal, František (advisor)
This master’s thesis is focusing on the research of chosen smoking types and their comparison in regard to emitted particles. Aerosol created during smoking represents a serious threat for human health. For purposes of this work an experimental set-up was constructed in the Laboratory of Aerosol Research at BUT FME and experiments simulating smoking process were carried out. The results of these experiments are presenting objective information about the constitution of produced aerosol which enters smoker’s lungs. There are many myths about the harmful effects of different types of smoking. The goal of this work is to verify and resolve these myths and set the foundation for possible upcoming research in this area.

Pokorná, Vendula ; Lukavská, Kateřina (advisor) ; Vanek, Marián (referee)
In my diploma thesis, I deal with description of the prevalence of use of twelve tobacco products in the population of Prague high school students. For these tobacco products, I am also investigating the differences in their use with regard to gender and type of school. Therefore, I am looking for differences in their use between girls and boys and between students of grammar schools and secondary vocational schools. In the most widely used products - combustible tobacco, electronic cigarettes without nicotine, electronic cigarettes with nicotine and heated tobacco, I also examine differences in the intention to use them in the future between girls and boys and between students of gymnasiums and secondary vocational schools. Furthermore, I deal with one of the most important determinants of smoking - the perceived harm of tobacco products and examine how the perceived harm of combustible tobacco, electronic cigarettes and heated tobacco affects their use and the intention to use them in the future by Prague adolescents. The main goal of my thesis is to demonstrate the relationship between the perceived harm of tobacco products and their use and intention to use them in the future. The data was obtained thanks to cooperation with secondary schools in the capital city of Prague, specifically in...
