Attitudes of high school students toward genetically modified organisms
Brousková, Mariana ; Janštová, Vanda (advisor) ; Čížková, Věra (referee)
The diploma thesis focuses on investigating attitudes of czech high school students toward genetically modified organisms (= GMO). The main objectives of this thesis are to investigate students' attitudes toward, and knowledge of GMO, to find out any relation between attitudes toward, and knowledge of GMO. I found out if there is any relation between students' attitudes toward GMO and other factors like family environment (level and type of eduction of parents, religion), school environment (teachers who teach students, school) or place of residence. Data colletion was carried out by quantitative questionnaire survey among 185 Czech students of Prague's and out-of-town's grammar schools from 10 different classes. My findings show that the attitudes of Czech students toward GMO are positive and are not influenced by gender, parents' education, the students' attitudes toward biology, type of students' planned studies at university or the location of their school. However, at the same time, a statistically significant difference was found in the case of free-time activities, the teacher who teaches students and the purchase of organic food. In the case of the students' knowledge, a significant difference was found in the case of the type of the father's education, the type of the students' planned...

New breeding techniques in crop plants
Brousková, Mariana ; Opatrný, Zdeněk (advisor) ; Cvrčková, Fatima (referee)
Nowadays when human population and demand for quantity and quality of food constantly grow, there is effort to improve technologies, which are used to functioning currently agriculture. Currently spectrum of crop plants, which are available for people, is one of main basis of agriculture. This spectrum is enriched of new cultivars or new crop by classical breeding for centuries. From the end of 20th century spectrum is further expanded on gentically modified plants. However, there were distrustfulness of human society and therefore genetically modified plants were legislatively restricted about their use and cultivation. Inter alia, for these reasons effective and socially acceptable alternatives of standart GM techniques were searched. Set of methods, which was named "New breeding techniques"- NBTs, provides such benefits. This work summarizes NBTs and explains basic principles of their use.
