The aim of the thesis is to create a system that will assist doctors in localizing and relocalizing positions on the human body. The considered use-case is the dermatological diagnosis of skin diseases. The thesis includes the design and implementation of a localization system for a medical instrument and a demonstration application. The system stores positions on a unique 3D model of a specific patient taken by a 3D scanner. According to the tests performed in the last part of the thesis, the proposed system can localize positions on the human body with accuracy in units of millimeters.

Media image of Václav Klaus and Vladimír Mečiar in selected press from the period of split of Czechoslovakia
Matějková, Kristýna ; Just, Petr (advisor) ; Charvát, Jakub (referee)
Czechoslovakia underwent a challenging transition from a communist regime to a democratic system in the 1990s. Some Slovak citizens perceived this period as their chance to seek emancipation. This desire, nourished by some political figures, started the division process of the Czechoslovak federation, which resulted in a series of bargaining between the two national prime ministers, Václav Klaus and Vladimír Mečiar. The citizens of the federation were waiting to see how their protracted meetings would unfold. And the only intermediary that could regularly bring them information, were the media. Nevertheless, through its important role of informing the public, the media also has a considerable power to influence what people consider important and what they think about. The way in which the media covered all events that led to the breakup may have had an effect on the public opinion on the existence of Czechoslovakia. This diploma thesis offers a view on how selected Czechoslovak press in 1992 portrayed the main characters of the final split of Czechoslovakia, focusing on the perception of Václav Klaus in Slovak media and Vladimír Mečiar in Czech media.

Populism as a discursive strategy: an analysis of the communication of selected populist actors in the Czech political arena
Křovák, Jan ; Charvát, Jakub (advisor) ; Just, Petr (referee)
This paper analyses the concept of populism as a discursive strategy. Therefore, it uses the view of populist discourse as discussed by Ernesto Laclau and other authors in their works. The author analyses the communication practices of four selected Czech political actors on social networks (Facebook and Twitter) in the period before the elections to the Chamber of Deputies of the Parliament of the Czech Republic in October 2021. For the analysis, the author chose representatives who are commonly labelled as populists, i.e. former Prime Minister Andrej Babiš, far-right populists, i.e. Tomio Okamura, and then two politicians representing mainstream parties - Markéta Pekarová Adamová from TOP 09 and Vít Rakušan from STAN. In the theoretical part, the author describes in depth the phenomenon of populism on the basis of expert literature, and in a comprehensive way points out the relationship between populism, social networks, media and political communication. In the practical part, the author conducted a so-called critical discursive analysis of posts of the politicians on the above-mentioned social media and then compared their dominant communication practices. The author then places the data and results of the research in context of the populist narrative described in the theoretical part of the thesis.

The electoral system to the Chamber of Deputies of the Parliament of the Czech Republic
Charvát, Jakub ; Bureš, Jan (advisor) ; Buben, Radek (referee)
The aim of this text is to analyse current electoral system to the Chamber of Deputies of the Parliament of the Czech Republic and its critics. Chapter one defines four main variables that are exclusively specific to list proportional representation systems - electoral district magnitude, electoral formula, legal threshold and the number and character of tier districting. Various combinations of these variables produce various proportionality of the representation authority. Chapter two presents descriptive analysis of the current electoral system to the Chamber of Deputies, by means of four main variables and a secondary variable - character of list of candidates (ballot structure). Chapter three is pointing to some of the critics of the current electoral system. In chapter four, there I present my project how to reform current electoral system. These changes are likely to have minimal effect on the electoral behaviour of voters and political parties. I propose: to modify the number of electoral districts from current fourteen to nine (by means of combination current small electoral districts), modification of the process of preferential voting (four preferential votes for each voter instead of current two votes and variable threshold for being elected by means of preferential voting from four to five per...

Nature as Myth
Charvát, Jakub ; Češka, Jakub (advisor) ; Skovajsa, Marek (referee)
What exactly do we mean by "nature"? What do people expect from "nature"? And how has our understanding of it changed? The M.A. thesis "Nature as Myth", using Barthe's two-tiered system of signs and myths as a methodological tool, attempts to answer these questions through an examination of various historical and literary sources. The thesis has a chronological structure, consisting of four parts: 19th century, 1918-1938, 1938-1989, and from 1989 until the present. It focuses on fiction, memoir, and the history of "back to nature" movements. It also deals with environmental and aesthetic issues. The last section touches on the representation of nature in advertisement. The thesis will demonstrate that in all four of the time periods the most common depiction of nature is as a place of escape - both literally and figuratively. key words: nature, hiking, tramping, scouting, woodcraft, recreation in the cabins and cottages, ecology

This project may produce more proportional electoral results than the...
