"The good coach": Subjective perceptions of coaching in performance athletes
Fialová, Kateřina ; Mudrák, Jiří (advisor) ; Vítek, Petr (referee)
This bachelor's thesis explores the lived experience of performance athletes with their coaches. The aim of the thesis is to identify key themes through which performance athletes describe their experience of the quality of their coaches' work and how they construct the concept of a "good coach" through these themes. The theoretical part of the thesis is divided into three chapters, introduce the various themes that are relevant to the research topic. Attention is paid to defining the coaching profession including coaching roles, coach typology, defining a good coach based on research studies and elaborating on motivational climate. The next chapter elaborates on motivational theories, with particular emphasis on self-determination theory. The next section of the thesis focuses on the personality of the athlete, emphasizing the Big Five personality theory and the determinants that appear to be important in the context of coaching. The empirical part of the bachelor thesis was conducted using a qualitative research design. Data collection was conducted through semi- structured interviews. 5 participants, 4 men and 1 woman, took part in the research. The interviews were transcribed and analysed using thematic analysis method. Based on this procedure, 9 themes were identified that were identified by...

Detection of Similar Binding Sites in Protein Structure Databases
Telčer, Jakub ; Hoksza, David (advisor) ; Galgonek, Jakub (referee)
The evaluation of protein-ligand binding site similarity is crucial in many fields, from drug repurposing trials to evolutionary studies. Current state-of-the- art methods achieve good results on the benchmarking datasets. However, the current approaches operate over pairs of binding sites and are not applicable for searching databases of unprocessed protein structures. In cases when the binding sites are unknown, they have to be firstly located by using binding site prediction algorithms. That significantly increases the upfront costs of creating large databases of similar binding sites. This work covers the current methods for assessing binding site similarity and explores the possibility of fast searching of large databases of related structures by presenting a simple method that allows faster than linear search without the need for identification of the precise locations of the putative binding sites. The proposed approach shows promising preliminary results that merit further investigation, although more insight is still needed.

War in Vietnam and the role of Television broadcasting in the United States of America
Ondrejková, Pavlína ; Groman, Martin (advisor) ; Cebe, Jan (referee)
In my thesis I focus and analyse how selected studies track the media's actions during the Vietnam War. I focus most closely on 1968 and the events of the Tet Offensive and examine how the media (mainly television) reflected these event. Through qualitative analysis, i also trace whether the selected studies support or refute the Pentagon's official statement that held the media responsible for America's failure in Vietnam. My analysis found that none of the selected studies support the official position that the media was responsible for the United States' loss in the Vietnam War, but all of the studies consider that the media played a very important role.

Title: The History of czech schools in nature and their development over the past 50 years from the Perspective of czech citizens Aim: The aim of this bachelor thesis was to investigate the personal experiences of Czech citizens with schools in nature. Respondents were primarily asked about the purpose, form, content, and significance of these schools. Methods: This bachelor thesis is a theoretical-empirical work with quantitative research, utilizing an online survey as the research technique. The survey consisted of 24 questions and was completed by 151 respondents who attended primary school in the Czech Republic. Results: The results showed that most schools in nature now last about one week, much shorter than in the past when they could last several weeks. These programs most commonly occur in the 4th grade, but some schools participate annually. 89.6% of respondents said learning took place only in the mornings, mostly indoors. For extracurricular activities, respondents most frequently mentioned hiking and nature games. The socialization goal was highlighted as key, emphasizing improved relationships among students and between students and teachers. Another benefit frequently mentioned was the opportunity to spend time in nature, especially important for urban children. Conclusion: Schools in...

Comparison of similarities of mass spectra and structures of small molecules
Malíčková, Viktorie ; Galgonek, Jakub (advisor) ; Škrhák, Vít (referee)
Methods for measuring the similarity of mass spectra and the structures of small molecules are crucial for advancements in medicinal chemistry, pharmacology, and metabolomics. One commonly used method for comparing the mass spectra of molecules is cosine similarity. This measures the similarity between two non-zero vectors by calculating the cosine of the angle between them. Comparing the mass spectra of molecules enables searching in molecular databases, clustering of spectra, and exploration of spectral libraries. Structural similarity is measured based on various molecular fingerprints, such as Daylight, RDKit, Atom-Pair, Topological Torsion, Extended-Connectivity fingerprints, and others. These fingerprints are compared using similarity coefficients. The methods for comparing structures and mass spectra of molecules mentioned can be applied using bioinformatic libraries such as RDKit and CDK for generating and analyzing structural fingerprints, and the MatchMS library for comparing mass spectra. The work provides a theoretical overview of molecular descriptors, including various types of molecular fingerprints and techniques for measuring structural similarity, as well as the principles of mass spectrometry and approaches to comparing mass spectra. The practical part of the work focuses on...

Use of ionic liquids for preparation of epoxy materials
Rebei, Marwa ; Beneš, Hynek (advisor) ; Machotová, Jana (referee) ; Polášková, Martina (referee)
Epoxy resins represent an important category of thermosets widely as coatings, electronic encapsulants, matrices for composites, etc., due to their beneficial properties, such as strong adhesion, high chemical and electrical resistance, and good processability. However, their curing reactions present some limitations, such as using catalysts (for example, organometallics, complexes and MOFs) which are active at high reaction temperatures. In most cases, these catalysts are toxic and require organic solvents. Consequently, alternative non-toxic catalysts/initiators that can promote well-controlled fast curing under mild conditions have been explored while maintaining sufficient thermomechanical properties of the formed epoxy networks. In this thesis, three different epoxy ring opening reactions induced by various imidazolium ionic liquids (ILs) were studied. The first subsection (4.1) discusses the step-growth epoxy-dicarboxylic acid polymerization in an imidazolium IL medium conducted under mild conditions (T = 80-120 řC). The IL was shown to act as both a solvent and an initiator/catalyst for the reaction. In addition, IL-anions (chloride, bis(trifluoromethylsulfonyl) imide, or methanesulfonate) strongly affect the progress of the reaction. It was found that the Cl- anion is the most effective...

Locally adaptive splines
Dian, Patrik ; Maciak, Matúš (advisor) ; Hlávka, Zdeněk (referee)
The aim of this thesis is to present some semiparametric methods used for estimating an unknown regression function. All approaches are based on a minimization of an ob- jective function, which is formulated as the sum of a loss and a penalization function. We present a reformulation of unsolvable problems due to infinite dimensionality as problems which are of finite dimensions, in the form of classical ridge or lasso regression. A crucial part in these methods plays a penalization parameter used to obtain a balance between the bias and the variability of the estimate. Techniques devoted to finding the optimal values of the penalization parameter are shown. Finally, applications of the mentioned methods on two simulated datasets are displayed. We focus on the local adaptivity of in- dividual approaches, as well as the computational intensity, which we shall compare. In addition, we analyse a new method proposed to find the optimal value of the penali- zation parameter. 1

Patient organisation from the perspective of patients and health care professionals - how we can enrich each other. Participatory research in urology patient care
Novotná, Hana ; Povolná, Pavla (advisor) ; Hradcová, Dana (referee)
This thesis focuses on the development of a patient organization for prostate cancer patients to link the medical system to the needs of patients and their loved ones. The research involved mapping the needs of patients and healthcare professionals through qualitative interviews. Findings suggest that patients evaluate their experience of the disease primarily through treatment and contact with health professionals, with communication with doctors playing a key role. However, the healthcare system still shows deficiencies in communication and information provision, thus not providing enough support to patients. At the same time, health professionals are found to be poorly informed about patient organisations, but with a willingness to cooperate in the future. In order to make the change, two sets of conditions were defined. Realistic conditions for the successful use of patient organisation services include informing patients and health professionals about their existence and activities, and actively encouraging patients to seek information. Idealistic conditions include a change in the perception of gender roles in society and greater involvement of patients in shaping the health system. The paper proposes steps to achieve these conditions, including the presentation of research findings and...

Molecular simulation of Lennard-Jones fluid as a task for physical chemistry laboratory
Krieger, Jakub ; Košovan, Peter (advisor) ; Kolafa, Jiří (referee)
Molecular simulations are capable of reproducing and predicting the behavior of real systems using a simplified model. Over the past 70 years, thanks to the rapid development of computers, this method has become an important part of various scientific fields. Thanks to their speed and low cost, molecular simulations can work hand in hand with a real experiment and in some cases even replace it. The didactics of this progressive method are in its beginnings at the Faculty of Science of Charles University, and its teaching is limited to master's and higher studies. In this work, we created and tested a task for physical chemistry laboratory, which can serve as a first introduction to molecular simulations for undergraduate chemistry students. The task, written in the interactive Jupyter Notebook environment, was designed based on modern pedagogical approaches of inquiry based learning, supplemented by a high level of scaffolding due to the complexity of the teaching content. The choice of simulating the model of supercritical argon described by the Lennard-Jones potential was based on the requirement for conceptual simplicity and the possibility of connection with already known concepts. Testing of the task on 12 students made it possible to create a time schedule, correct errors, identify the most common...

Motivation to sport climbing
Brezina, David ; Turčová, Ivana (advisor) ; Baláš, Jiří (referee)
Title: Motivations of Climbers for Sport Climbing Objectives: The aim of this bachelor's thesis was to determine what motivates climbers to engage in the activity of sport climbing. Additionally, we investigated the influence of age, gender, and duration of climbing practice on climbers motivation. Methods: The research was conducted through a survey among 78 sport climbers (37 women and 41 men) in the Czech Republic. The survey inquired about various aspects of climbing motivation, such as personal reasons, risk perception, and social factors influencing participation in climbing activities. The survey included a total of 14 closed or semi-closed questions with selectable options. The results were processed using Microsoft Excel and Google Forms. Results: We found that the most common motivations for sport climbing are: overcoming personal limits and fears, the desire for physical improvement, the social aspect-meeting friends and building community, and the climbing activity itself. Furthermore, we discovered that younger climbers tend to seek adventure and excitement more. Older climbers cited being in nature and the climbing activity itself as their main motives. Both genders mentioned the social and communal aspect as an important motivation. Men leaned more towards the physical challenge and...
