The Impact of Load Folowing in Providing System Services of the Selected Dukovany Power Plant Unit on the Parameters of the Core
Kaňa, Jiří ; Ing. Jakub Lüley, PhD., ÚJFI FEI STU v Bratislave (referee) ; Katovský, Karel (advisor)
To operate safely and reliably, the power grid needs power sources that are capable of providing flexibility. In the scenario that emission-free sources dominate the energy mix, the provision of these services will largely be the responsibility of nuclear power plants. Changing the output of a nuclear power plant is burdened with a number of specificities that need to be respected compared to the output changes of thermal power plants. This thesis explores the possibilities of using the reactor at the Dukovany power plant to provide load-following. From a theoretical point of view, it presents information on the needs of the power system, the general possibilities and limitations of using nuclear power plants for load-following and presents the historical context of this practice. After applying different scenarios of load-following, the simulation results are assessed from safety, operational and economic points of view.

Development and Deployment of a Platform for Efficient Data Collection and Visualization in Opportunistic Sensor Networks
Chovancová, Emília ; Miklánek, Štěpán (referee) ; Musil, Petr (advisor)
Oportunistické senzory predstavujú zaujímavú alternatívu ku získavaniu cenných informácií a dát, ktoré šetria zdroje ekologicky a ekonomicky. Do tejto kategórie patria aj dané meteorologické meradlá a snímače, ktoré sú opísené v rámci tejto diplomovej práce a ktoré budú v budúcnu využívané pre porovnávanie s inými mikrovlnnými spojmi. Cieľom práce bolo vytvoriť technickú dokumentáciu ku príslušným meradlám, v nej opísať ich technické vlastnosti, tok dát a navrhnúť bezepečnostné vylepšenia infraštruktúry. Ďalším cieľom bolo vytvorenie webovej aplikácie, ktorá má umožňovať optimalizovanú vizualizáciu dát v reálnom čase a tým informovať užívateľov o aktuálnych klimatických podmienkach v rámci FEKT kampusu.

Ensuring availability and security in industrial networks
Zatloukal, Zdeněk ; Fujdiak, Radek (referee) ; Holasová, Eva (advisor)
Currently, a key aspect of industrial automation is ensuring a high level of security, reliability, and data availability in industrial communication networks. Given the rising cyber threats, it is essential to develop and implement advanced strategies for protecting industrial infrastructures. This thesis aims to perform a comprehensive analysis and development of security solutions for industrial networks, focusing on the Modbus RTU/TCP and MQTT communication protocols, which are crucial for the effective management of modern industrial operations. The work employs methodological approaches that combine theoretical research with practical experiments. It includes an analysis of existing protocols, the design of communication security through these protocols, and their subsequent testing in a controlled industrial environment to verify security, efficiency, and reliability. The analysis revealed significant deficiencies in the security of existing systems and led to the integration of new security measures into the industrial switchgear, which significantly improved the protection of data and communication infrastructure. The implemented solutions demonstrate significant progress in protecting industrial networks against various types of attacks. This thesis represents a significant contribution to the field of industrial network security. The results of the work provide valuable information for the further development of security technologies in the industry and offer practical guides for engineers and technicians who are working on improving the security status of industrial systems.

Security Testing Tool for Industrial Devices
Pospíšil, Martin ; Člupek, Vlastimil (referee) ; Fujdiak, Radek (advisor)
The master thesis is focused on the issue of security of industrial devices in information networks. The theoretical part first describes the convergence of operational and information technologies. It then focuses on the industrial protocols Modbus TCP and OPC UA, security models, and an analysis of the current state of security testing. The practical part of the master thesis details the design and implementation of the developed tester and the methodology created for testing purposes. In conclusion, experimental testing of two industrial devices with the above communication protocols is conducted.

Safe administration of injectable medications
VANÍČKOVÁ, Eliška
Introduction: Drug administration is an essential part of nursing practice. Following the example of other countries, the safety of drug administration is coming to the fore. Nowadays, patient safety is a key element in the provision of quality nursing care. The aim of this thesis was to map the procedure of drug administration by intramuscular and subcutaneous routes. Methodology and research sample: For the purpose of this thesis, the method of participant observation was chosen, which took place in the departments of internal medicine and surgery from August to October 2023. All observations were recorded in a pre-designed record sheet and the data were statistically analysed using SASD and SPSS software. The analysis was based on first and second level classification, contingency tables with absolute and relative frequencies and sign scheme were constructed. The results were then organised into graphs and tables. Results: The results of the thesis indicate that the nurses observed do not follow the labelling of injections to a considerable extent, which can lead to errors. Furthermore, in a significant number of cases the nurses do not take care to properly disinfect the injection site of the injectable drug, which leads to a higher likelihood of signs of inflammation at the injection site. A surprising finding was the precision in hand sanitation. This behaviour is very important because, in combination with careful disinfection of the injection site, it is more likely to prevent the introduction of infection into the patient's body. Conclusion: The thesis provides a comprehensive view on the issue of safe administration of injectable medicinal products. As a result of this work, it will be presented at a student conference and an article will be written on the subject.

Tourism participants' psychological responses to terrorism and related security threats: Geographical conditionality and manifestations
Krajňák, Tomáš ; Vágner, Jiří (advisor) ; Siwek, Tadeusz (referee) ; Daněk, Petr (referee)
Existing literature examining the impacts of safety and security on tourism has paid considerable attention to the role of the psychological responses of tourism participants. It has also confirmed the centrality of these responses in the process of how security threats influence tourist behaviour. However, no attempt has been made to clarify whether the psychological responses are also geographical in nature. The dissertation primarily intends to address this shortcoming by examining the influence of political- security threats. Therefore, its main aim is to identify and clarify the geographical conditionality and manifestations of tourism participants' psychological responses to terrorism and related security threats. The empirical part of the dissertation is the result of several conducted studies published in four journal articles. Therefore, multiple methods of data collection and analysis were used to achieve the main aim of the thesis. The work required a certain pragmatic approach to engage both positivist and more interpretivist methods. Still, consistency between the philosophical starting points and the adopted methods was not neglected, as it prevailed in the treatment of the sub-aims and in the resultant publication outputs. Specifically, the methods employed include a systematic...
