Automatic detection of fake-news on Slovak texts
Romanský, Patrik ; Mareček, David (advisor) ; Novák, Michal (referee)
Fake news is a problem in recent years. This study focuses on detecting fake news written in the Slovak language using text classification methods. It is unique because it is the first to conduct such a comprehensive set of experiments on Slovak. During the study, a balanced dataset was created, and over 80 experiments were conducted to find the optimal classifier for the problem. Pre-trained transformer-based language models, including BERT, mBERT, RoBERTA, XLM-RoBERTa, and SlovakBERT, were used in the initial step of the study, and their performance was compared against other machine learning methods using standard metrics. The models were fine-tuned with LIAR and COVID19 FN, English-language datasets, to test the impact of fake news topics and language transfer properties. SlovakBERT combined with training exclusively on Slovak datasets achieved the best results with an (acc = 0.9610). This study can contribute to the development of tools to automatically detect fake news in Slovak, aiding in the fight against the spread of false information. 1

Employee benefits of pedagogical staff of selected schools
Novák, Michal ; Hubert, Vlastimil (advisor) ; Tureckiová, Michaela (referee)
The bachelor's thesis focuses on the provision of employee benefits to teaching staff and the use of this area as a human resource management tool for school management. The thesis is divided into a theoretical and a empirical part. The theoretical part of the thesis summarizes knowledge about the issue from the professional literature, defines basic terms and serves as a basis for the following practical part. The empirical part describes the method of setting the goals of the thesis, i.e. describing the use of providing benefits as a human resource management tool from the point of view of the management of selected schools, the methodology of the research and presents the results of the research, including their interpretation and discussion. Qualitative research was carried out at three selected secondary schools in Prague, using semi-structured interviews with school principals and a subsequent questionnaire among the pedagogical staff of the given schools. The result of the research is an answer to the research questions, i.e. how the management of selected schools uses employee benefits as a human resources management tool, what benefits are offered to the teachers at selected schools and which benefits are the most popular among teachers at selected schools. The research shows that the...

Knowledge comparison of laymen and experts about selected oil accidents
NOVÁK, Michal
Oil spills are an unfortunate part of industrial development so an active prevention is demanded. When such an event occurs, adequate measures need to be taken. The goal of the diploma thesis is to analyze law regulations, documents and information about preselected oil accidents around the world and in the Czech Republic. This thesis also evaluates the knowledge of experts and lay public in the field of oil accidents, while using preselected methods of descriptive and mathematical statistics. Following hypothesis H was chosen to achieve the adequate results of the diploma thesis: "The answers of groups of laymen and experts differ in the case of all questionnaire questions." Theoretical part of this thesis outlines the issue of oil, including general knowledge about its origin, chemical characteristics, oil extraction, processing and areas such as world oil consumption and oil logistics. Storage of oil is also a chapter contained in the theoretical part of this thesis, before it started to focus on the very core of research, oil accidents. These types of accidents were processed by using specialized documents, thanks to which relevant knowledge about individual types of oil accidents were ascertained. The research part was based on the evaluation of answers, which were collected, by using a questionnaire survey. Based on the results of the evaluated knowledge of laymen and experts in the field of oil accidents, the selected hypothesis was getting solved. A total of 105 people took part in the quantitative data collection. For lucidity, the final results are graphically portrayed. Based on the results, which were interpreted in the practical part of this thesis, hypothesis H was rejected. Based on descriptive statistics, the tables for the number of correct answers from lay people and from experts show a proximity to the normal distribution for lay people and a proximity to the Poisson distribution for experts. The diploma thesis brings theoretical and practical knowledge and the possibility to take advantage of the results, not only throughout the academic sphere. This topic also has the potential for follow-up work creation.

Novák, Michal ; Oláh, Vladan (advisor) ; Omcirk, Dan (referee)
Title: Strength exercises for the prevention of knee injuries in drop landing: a sysmatic review. Objectives: This study aims to create an incidence overview of strength exercises for the prevention of knee injuries during drop landing using a systematic search of scientific databases. Methods: For an elaboration of this thesis was used the systematic review method based on recommendations of PRISMA (Page et al., 2021). At the beginning of the thesis, a research question was defined to identify the most common strength exercises in intervention programs to prevent drop landing injuries. Next, a script was created using defined keywords and Boolean operators such as AND, OR and NOT. The script was used to retrieve studies from internet databases (Web of Science, SportDiscus, Scopus, PubMed). Duplicates were subsequently excluded from the retrieved studies, and the number of studies was further reduced by expert review according to predefined criteria. Results: According to the results of this bachelor thesis, lunges are the most common exercise used in intervention programs to prevent knee injuries during drop landing. They were used in 13 out of 24 intervention programs. In addition to strength exercises, plyometric exercises are widely used in intervention programs. Keywords: Strength training,...
