Maintenance and diagnostics of machine tools focusing on vibrodiagnostics, electrodiagnostics and tribodiagnostics
Houška, Jan ; Řezníčková, Hana (referee) ; Hammer, Miloš (advisor)
Master‘s thesis deals with maintenance and related technical diagnostics of machine tools. Diagnostics methods on which is the thesis focused are vibrodiagnostics, tribodiagnostics and electrodiagnostics. Work includes design of diagnostic system and measurement of vibration and electrical parameters of the machining center. Based on given results from data evaluation, further steps in predictive maintenance and usage of technical diagnostics for machine tools are recommended. Within tribotechnical diagnostics, the thesis is based on evaluation of long-term monitoring of process liquid status, which was used in several machining machines. A procedure for the measurement of selected parameters is proposed and periodical liquid status checks are established.

Analysis of Final Scores in Czech Video Game Media
Svoboda, Filip ; Houška, Jan (advisor) ; Švelch, Jaroslav (referee)
In a video game review, it is common to include a numerical recommendation rating in addition to a textual evaluation of the product (game). How (on what scale and how to use such scale) and whether to evaluate numerically or otherwise is a subject of extensive debate in the video game journalism context. The thesis aims to answer the question of how video game reviewers perceive the problematic aspects of the final scores through the interviews with Czech game reviewers. It compares the findings with each other and provides context. It also maps how scoring systems have changed over time.

League of Legends Player Community Toxicity
Wija, Jakub ; Fousek Krobová, Tereza (advisor) ; Houška, Jan (referee)
This thesis describes the toxic behaviour of League of Legends gaming community. It offers definitions of toxic behaviour as a communication-behavioural phenomenon that results from disruptive behaviour. It also describes types of toxic behaviour such as cheating, sabotage, mediocritizing, hostages-holding, and communicative aggression, on which I focused in this thesis. This thesis takes a closer look at hostility towards female and queer gamers and describes phenomena such as toxic geek masculinity or the incel movement. The main aim is to familiarize the reader with the issue and represent the perspective of the victims of this type of behaviour. The perspective is explored in the thesis through qualitative research in the form of semi-structured interviews. The research sample consisted of six respondents. Three respondents who identify as queer players and three respondents who identify as female. The interviews focused on how they perceive the toxic behaviour of the League of Legends community and how they perceive the game title itself. Amongst other, the analytical part includes the male and female respondents' experiences with hate speech or the strategies they use to cope with this type of toxic behaviour.

Comparison of profesional reviews and user comments on Metacritic in the case of The Last of Us Part II
Kafka, Pavel ; Švelch, Jaroslav (advisor) ; Houška, Jan (referee)
The subject of this thesis is to analyze and compare professional reviews and user comments on the aggregator Metacritic in the case of The Last of Us Part II. The goal of this thesis is to find out what distinguishes professional video game reviews from user comments, what dominant themes they contain and which of them play a major role in the final evaluation, on the example of The Last of Us Part II. First four chapters of the theoretical part of this thesis deal with the theoretical basis of the areas of game review and its function, review bombing, identification with protagonist and representation of female characters. The theoretical part ends with the introduction of The Last of Us Part II and the aggregator Metacritic. The research part contains a total of two surveys. The first two chapters are devoted to the introduction of methodologies of individual surveys and the definition of their research samples. The first research uses quantitative methods to describe the course of the user score over time. The second research uses qualitative thematic analysis to identify dominant themes in 10 professional reviews and 100 user comments. The dominant themes of these two research samples and their impact on the final evaluation are then compared with each other. The thesis ends with a discussion,...

Representing Death in Contemporary Computer Games - the case of The Last of Us II
Valtonen, Veronika ; Švelch, Jaroslav (advisor) ; Houška, Jan (referee)
The work deals with the analysis of the representation of death in computer games, specifically in the case of The Last of Us II, a survival horror genre. The analysis notices the differences in the representation of death in games compared to real life, where games significantly downplay the subject of death, and at the same time death is the main game mechanics that rewards the player as a successful killer. Games can stereotype death in a harmful way, but the studied game is specific in that it does not contain these common stereotypes. The work analyses main and secondary characters in order to find out how they die and how their deaths differ from each other. Protagonists and antagonists are also point of interest, as their death is different therefore an appropriate subject to examine what the game is trying to convey. These differences will be further analysed in the work in the context of game mechanics and audio-visual representation. Narrative is the main aspect representing death in the game. The consequences of death are also part of the narrative, and the work will focus on the aspects of burial and mourning. To achieve the findings within the representation of death in the game world, the work will analyse characters perception of the death, specifically through their dialogues or...

The Fight against Evil: Stereotypization of Antagonists in War-Themed Shooters
Houška, Jan ; Švelch, Jan (advisor) ; Krobová, Tereza (referee)
Using the method of qualitative content analysis, my research is focused on the visual and ideological representation of antagonists in eight PC games of first-person shooter genre (FPS), released between 2007 and 2019. The analysis is based on the identification of the stereotypical antagonistic representations. Its main attention is devoted to the ethnic and national stereotypes, because antagonists are ethnic and national Others in relation to protagonists. I aimed to define another summarizing and defining criterion of antagonistic representation, apart from the categories of othering already mentioned. In my thesis, I also describe ideological aspects which frame antagonistic representation. For the analysis of ideological content, I use Pötzsch's selective realism, which, by means of the four filters (violence, consequence, character and conflict) excludes negative and controversial aspects of war from FPS games. Not only does selective realism presents war selectively, it represents antagonistic actions selectively, too. In the text, I identify the stereotypical representations of three ethnic-national groups - orientalism and Cold War stereotypes in the case of Russians, neo-orientalism in the case of Middle Eastern antagonists and techno-orientalism in the case of East Asians. The ideology...
