Processes of open-die and die forging
Tvrdoň, Radek ; Peterková, Eva (referee) ; Lidmila, Zdeněk (advisor)
The thesis presents a theoretical summary of forging processes. It deals with the selection of semi-finished product, machine and also forming processes for both types of forging. It explains the usability of open-die forging for making simple parts and die forging for more complex components. While solving the die forging, the thesis is extended with instructions for making a drawing of a forged piece, which nominal dimensions are extended by mentioned additions. The drawing is followed by explanation of procedure of creation a die cavity, which is different for presses and hammers. The thesis also describes the process of calculations of forging force and labor.

Production of air filter cover
Procházka, Vojtěch ; Žák, Ladislav (referee) ; Podaný, Kamil (advisor)
The thesis is concerned with the concept of an air filter cover production .The component has a cylindrical shape with a circular protrusion and a hole in the bottom. It is made of a steel sheet 11 320 with the thickness 1 mm. Considering the production volume of 20,000 units per year, it was chosen as the most suitable pulling technology with a conventional tool without wall thinning. The component needs to be pulled in two operations, each time a retainer has to be used. The tool for each operation is separate. Technical drawing documentation is processed for the second tool. Due to the calculated force, the ŽĎAS CTH 250 hydraulic press with a nominal force of 2,500 kN was chosen. The economic evaluation shows that the production material cost for one piece is about 42 CZK. The cost of the second stroke tool is 260,000 CZK.

The reaction of selected Czech and German periodicals of the First Czechoslovak Republic to the Anschluss of Austria
Wybitulová, Berenika ; Šmidrkal, Václav (advisor) ; Kunštát, Miroslav (referee)
This bachelor thesis explores the Anschluss of Austria and its media image in selected Czech and German periodicals of First Czechoslovak Republic. The aim of the thesis is to present the narratives that shaped the news coverage of this historical event, and at the same time to show the influence of state-controlled mechanisms on the form of news about the Anschluss. The first chapter of the thesis introduces the media landscape of the First Republic, consideringthe connection of the Czechoslovak News Agency (ČTK) to state authorities or censorship measures during this period.In particular,it focuses on the phenomenon of party and non-party newspapers, as it is party and non-party periodicals across the political spectrum that are analysed in the second chapter of the thesis.In this section, the circumstances of the Anschluss are first briefly described, then the thesis analyses the impact of this situation on Czechoslovakia's international position and diplomatic relations. The analysis itself relies on archival findings that document the communication between the ČTK and state institutions during March 1938, and uses these findings to evaluate the content and wording of the articles in the various periodicals.Most of the periodicals agree that Czechoslovakia was not in danger after the Anschluss...

In the second chapter are first summarized history of IOJ and described main phases of IOJ's development - these are periodizated according to IOJ's Congresses. An integral part of the description and periodization is quotation of main international and Czechoslovak political circumstances, which had a real impact on the organization. The next text is followed by IOJ's objectives, aims, activities and structure. Finally, the IOJ's main persons and the curriculum vitae of the five leaders are mentioned.

"Katolická akce" as a tool of communist propaganda for christians in Czechoslovakia in 1949-1951
Zindulková, Magdalena ; Suk, Pavel (advisor) ; Groman, Martin (referee)
The aim of this thesis is to show the specific elements of propaganda that the communist regime used to speak to Christians in Czechoslovakia in the years 1949- 1951 using the so-called Catholic Action. This movement was a tool of the communist regime that wanted to subjugate the Catholic Church and use it for its own purposes. Catholic Action was artificially maintained for almost two years and used in the press primarily as a supposed mouthpiece for all Catholics. Eventually, it disappeared from the pages of the newspapers. This thesis describes selected elements of propaganda using specific examples from periodicals of the time. The results can help us to gain insight into the mindset of the former communist regime.

Elements of Propaganda in the Image of the Chernobyl Disaster in Czechoslovak Press
Vladyka, Tomáš ; Suk, Pavel (advisor) ; Cebe, Jan (referee)
On 26 April 1986, the worst nuclear accident in human history took place at Chernobyl in Ukraine. In addition to the massive loss of human lifes (it is estimated that hundreds of thousands of people died indirectly as a result of radiation), the accident had devastating effects on nature far and wide. In the first part of my thesis, I use literature to describe the reality of how the accident actually occurred and what its consequences were. Then, through an analysis of articles in the Czechoslovak press of the time (Rudé právo - the central daily of the Communist Party of Czechoslovakia; Týdeník aktualit - published in Czechoslovakia by the Soviet Novosti Press Agency), I present a comprehensive picture of how the Chernobyl accident was presented to Czechoslovak readers in comparison with reality. The depiction of the accident is also examined in contemporary Czechoslovak television coverage. In order to compare the depiction of the accident in the West, I further analyze articles in The New York Times. Part of the thesis also focuses on an examination of the archival holdings of the Central Committee of the Communist Party of Czechoslovakia to refute or confirm the hypothesis that there is evidence of instructions to journalists on how they should write about the crash.

The path of Italian fascists to power and its reflection in the Czech press
Klouda, Daniel ; Mejstřík, Martin (advisor) ; Matějka, Ondřej (referee)
This bachelor's thesis examines the rise of the Italian fascist movement from 1920 to 1922 and its reflection in selected Czech press. The theoretical part focuses on the Czech media landscape after World War I, followed by a description of the historical and political context of the events observed in Italy, briefly outlining the history of the fascist movement from its origins to Mussolini's appointment as prime minister. The practical part involves a qualitative analysis of articles covering six selected events involving Italian fascists, which were significant for the fascist movement. The choice of these events was influenced by their violent nature - through their violent actions, the fascists eliminated opposition and subsequently managed to discredit and undermine state authority and sovereignty to the extent that their rise to power seemed inevitable. The aim of this work is to monitor and compare interpretations of this development through selected events in three Czech newspapers: the national-democratic Národní listy, the independent Lidové noviny, and the communist Rudé právo. The thesis aims to analyze whether and how the ideological convictions of these newspapers were reflected in the rhetoric used to describe the fascist activities in the examined articles.
