Zeman, Kryštof ; Vozňák, Miroslav (referee) ; Gaydamaka, Yulia (referee) ; Hošek, Jiří (advisor)
Předkládaná disertační práce je zaměřena na \uv{Modelování propagačního kanálu pro off-body komunikaci v oblasti milimetrových vln}. Navzdory pokrokům v rámci bezdrátových sítí v přímé blízkosti člověka stále systémy 5. generace postrádají dostatečnou šířku pásma a dostatečně nízkou odezvu. To je způsobeno neefektivním využíváním rádiového spektra. Tento nedostatek je potřeba co nejdříve odstranit a právě z tohoto důvodu je hlavním cílem této práce navrhnout vylepšený model rádiového kanálů pro off-body komunikaci. Úkolem tohoto modelu je umožnit uživatelům efektivněji a přesněji simulovat propagaci signálu v rámci daného prostředí. Navržený model je dále optimalizován a ověřen vůči nejnovějším měřením, získaným z literatury. Nakonec je tento model implementován do simulačního nástroje NS-3, pomocí kterého je následně využit k simulaci množství scénářů. Hlavním výstupem této práce je ověřený model přenosového kanálu pro off-body komunikaci v rámci milimetrových vln, společně s jeho implementací do simulačního nástroje NS-3, díky čemuž je dostupný pro širokou veřejnost.

Endoparazité daňčí zvěře na Úsovsku
Heinzová, Zuzana
The aim of my bachelor thesis was to record the occurrence of endoparasites in European fallow deer in females, males and young. In 2018, a regulation was issued by the State Veterinary Administration banning the use of antiparasitic drugs for cloven-hoofed game. The measure was intended to prevent the spread of a dangerous disease, namely African swine fever. Previously, antiparasitic drugs against parasitic diseases were commonly treated in my chosen area. Part of my bachelor's thesis was to compare the results before and after the imposed ban. Treatment with antiparasitic drugs is now possible with an exemption, once parasites have been demonstrated in ungulates and under certain conditions.

Perception of the "culture wars" concept in American media
Šimek, Jan ; Just, Petr (advisor) ; Charvát, Jakub (referee)
American society is going through an era of deep social and political divisions. At the forefront of this deepening divide are the so-called culture wars, an umbrella term for a set of narratives around cultural and social issues that both sides of the conflict use to advance their political goals. This thesis aims to determine how much space culture wars themes occupy in the production of selected American media outlets, how these themes are projected onto their audiences and how this influences the audience's trust in the mainstream media. The first part of the thesis presents the methodology used in collecting and evaluating the data used in the research for this thesis. The theoretical section also defines concepts and terms related to the topic of the thesis. The practical part of the thesis will then focus on the evaluation of the data from the questionnaire survey conducted among American media consumers between May and June 2023.

Campaign to stop 'killer robots': prospects of a preemptive ban on autonomous weapons systems
Rosendorf, Ondřej ; Smetana, Michal (advisor) ; Hynek, Nikola (referee)
This thesis addresses the issue of autonomous weapons systems and their potential preventive prohibition with regard to current international discussions at multilateral forums such as the Human Rights Council, First Committee of the General Assembly, and Convention on Certain Conventional Weapons at UN. The aim of this thesis is to provide an extensive empirical account of the substance of those discussions and their most likely outcome, estimating state preferences with use of content analysis and the likely outcome with median voter prediction. From a theoretical standpoint, the thesis draws from defensive realism and contributions of arms control, arms trade as well as institutionalist literature from which it draws the concept of legalization. From a methodological standpoint, the thesis relies on quantitative methods, in particular, content analysis for collection of data and median voter theorem for prediction of the likely outcome. In addition, the thesis uses the method of regression analysis to examine states' activity at the aforementioned fora. In conclusion, the thesis finds that the most likely outcome of discussions on autonomous weapons systems is a moderate-obligation form of hybrid regulation, which includes solutions such as framework convention and moratorium. Further finding of...

Rules, bans, restrictions in healthcare facilities
KODETOVÁ, Věra
Rules, bans, restrictions in healthcare facilities Improving the quality of care for patients is the main goal of every healthcare facility. Satisfaction of patients with medical and nursing care is one of the indicators of quality. Patients have not only rights but also duties. Among other things, patients{\crq} duties include compliance with rules, bans and restrictions during a visit to healthcare facilities. This particularly concerns compliance with therapeutic rules, instructions given by a physician and other limitations associated with the operation of a healthcare facility. The main objective of this diploma thesis was to identify the patients{\crq} attitude and perception of rules, bans, and restrictions, find out how patients observe them and compare the number of rules, bans and restrictions in both outpatient and inpatient healthcare facilities. The data was collected in a survey undertaken in Nemocnice s poliklinikou Praha Italská (Hospital with Outpatient Clinic Prague Italska). This healthcare facility has 2 hospital wards and 31 specialist outpatient departments. A total of 188 respondents took part in the survey (102 outpatients and 86 inpatients). Five hypotheses were proposed. The first hypothesis, which predicted that most patients would perceive rules, bans and restrictions as burden, was not confirmed. The second hypothesis, which predicted that rules, bans and restrictions that were personal would create more stress in female patients than in male patients, was confirmed. The third hypothesis was also confirmed since female patients from outpatient departments of the healthcare facility were shown to be more compliant with rules, bans and restrictions than male patients. Female inpatients from hospital wards of the healthcare facility were not more compliant with rules, bans and restrictions than male inpatients. The fourth hypothesis was not therefore confirmed. Our assumption that inpatients from hospital wards of the healthcare facility are facing more rules, bans and restrictions than outpatients was disproved. The fifth hypothesis was not therefore confirmed. The author has chosen this topic for her diploma thesis because as a nurse she meets different kinds of patients on a daily basis who react differently to rules, bans and restrictions in this healthcare facility. The results of the survey led us to design training classes for nurses and information brochures for patients who visit healthcare facilities. A sufficient amount of information is a basic prerequisite for understanding and complying with rules, bans and restrictions.
