The Reflection of the Vietnam War in American Cine from the End of the 1960s to the Beginning of the 2000s.
Porš, Jaroslav ; Kovář, Martin (advisor) ; Soukup, Jaromír (referee)
(in English): This thesis deals with the second war in Indochina (American Vietnam War), its causes, course, political and international contexts and, in particular, its representation in American cinema in the second half of the twentieth century and the beginning of the twenty-first century. In the main part of this thesis, I introduce the most important films dedicated to the Vietnam War while comparing and showing the different approaches of directors to this topic. I present films that deal not only with the war in Vietnam, but also topics that are immediately connected to it, such as the draft, returning veterans and their problems or war heroes. For each movie I endeavor to show the artistic quality or flaws and emphasize the political attitudes of the directors and their relationship to the Vietnam War.

Application of bioscanners and videotechnique for studies of fish migration
Porš, Jaroslav ; Kalous, Lukáš (advisor) ; Lucie, Lucie (referee)
In recent years there has been a significant decrease in abundance and species diversity of migrating fish. A significant decrease was recorded especially in diadromous fish species such as Atlantic salmon (Salmo salar) and eel (Anquilla anquilla). A significant population decline was also observed in potamodromous abundant fish species. Transverse barrier which prevents fish migration in rivers and impaired water quality are considered as the main causes of this situation. At present there is being improved a surface water quality, habitat rehabilitation and restoration of the possibility of free migration of aquatic animals. Design and construction of fish ladders are the most important factors to improve conditions of the fish migration. Closely related to this is a migration permeability testing of these fish ladders while the biological function and the activity of a single technical solution is evaluated. A non-invasive automatic monitoring method using a bioscanner Riverwatcher was selected to assess the functionality of fish passage on the river Ohře in Kynšperk nad Ohří. Bio scanner was installed at the end of the track of fish passage. Riverwatcher camera system, a product of Vaki Aquaculture Systems Ltd., was used in the Czech Republic for the very first time. Direct catches of fish samples in the river using an electric unit (section under fishway) were also used for the data collection. Size and species selectivity was tested at the fish ladder. The influence of external factors affecting the course of migration, such as flow rate, water temperature and light, was monitored at the same time.
