Application of cooperative game theory in Cournot oligopoly
Eryganov, Ivan ; Mazal,, Jan (referee) ; Hrdina, Jaroslav (advisor)
This Master’s thesis deals with the application of cooperative game theory for solving the problems of Cournot's oligopolies. The knowledge of oligopoly theory and game theory has been elaborated to build a model describing the behavior of companies at a market that meets the preconditions of Cournot's oligopoly. The definition of cooperative game is based on the -characteristic function, which takes into account, compared to classical methods, that companies which are not in the coalition are pursuing their own profits, not suppressing coalition positions. The properties of the resulting cooperative games are examined in detail, focusing on monotony and convexity. Several theorems about these properties have been derived and their economic interpretations are given. Also, the question of calculation of the -characteristic function using the best-reply dynamics algorithm is being solved, and its convergence for a given type of games is justified. The model is applied to data from the oil market, which is further characterized by the results of the cooperative game.

Subjective perception of nurses fatigue in the ward with Covid-19 positive patients
Vosátková, Laura ; Jirkovský, Daniel (advisor) ; Haluzíková, Jana (referee)
The bachelor thesis deals with the workload of nurses caring for COVID-19 positive patients. The aim of the questionnaire survey was to determine the workload of these nurses and to determine whether the workload of the Covid-type ward exceeds the workload of the standard non-Covid ward. Data collection took place in the inpatient, ICU and ARO wards of the Rudolf and Stefanie Hospital in Benešov, which cared for COVID-19 positive patients. The questionnaire survey took place from November 2021 to January 2022. The target group of respondents consisted of practical and general nurses. A data sheet created by Microsoft Excel was used for data processing, and STATISTICA CZ 12 was used for basic statistical analyzes and frequency tables. From the results of the survey it was found that the share, resp. 73.44 % of respondents reported a rate of subjective experiences that matched congestion in Covid's department. 90.63 % of respondents reported a share of subjective experiences in the Covid department that corresponded to monotony. The share of the combination of subjective experiences of overload and monotony was stated by 67.19 % of respondents. 20.31% of respondents and 1.56% of respondents experienced an unfavorable workload in the ward with COVID-19 positive patients. It can be concluded that the...

Functions in examples and counterexamples
Janda, David ; Pilous, Derek (advisor) ; Zhouf, Jaroslav (referee)
The aim of my Bachelors thesis is to explicate students coming to the uni- versity the key problems in fundamentals of mathematical analysis. I focus on the most notable terms of continuity and limit, which these secondary students were acquainted with. However, majority of them just intuitively and informaly. I am trying to point out the fact, that the knowledge of many students is distortid and uncomplete. As a result it is necessary to practise and clarify this knowledge so that the intuitive imagination of these terms corresponds to the formal definition. I am trying to get this point by brea- king of intuitive imaginations of students by counterexamples. Important is a chapter named The Construction of Functions, which contains instructi- ons leading to the finding functions with specific features. Not only these features, described in this thesis, but also more complex such as derivation, primitive function or uniform convergence. It is a consequence of the fact, that the principle of examples to practise these terms is in many sights similar and repetitious. In chapters named Continuity and Limit, I am interpreting these terms using the special examples, which are in my opinion optimal for rehearsing. My intention is to help illustrate selected problematical sections of mathematical analysis.

Pharmacist's health aspects of stress
Čavajdová, Barbora ; Švarcová, Eva (advisor) ; Loudová, Irena (referee)
Charles University, Faculty of Pharmacy in Hradec Králové Department Department of Social and Clinical Pharmacy Candidate Barbora Čavajdová Consultant PhDr. Eva Švarcová, Ph.D. Thesis Title Pharmacists' health aspects of stress Introduction: Pharmacists working in pharmacies may be subject to some strain and stress. The main task of this profession is the dispensing of medicines when you need to be very attentive and responsible. With the action of stressors and the consequent stress there are manifestations of fatigue which disappear with rest. Working conditions are an important factor that affect the overall mental and physical condition of the pharmacist. Objective: The aim of the thesis was to evaluate the degree of fatigue of pharmacists by analysing working conditions and based on the results to recommend proposals for improving health and working conditions in pharmacies. Methods: The method was based on a questionnaire survey, where pharmacists responded to the degree of fatigue in the area of subjective feelings of fatigue, vision problems and problems associated with the musculoskeletal system. Questionnaires were filled in by pharmacists from chain (Benu and Dr.Max) and other pharmacies, then the results were compared. Out of 200 questionnaires, 160 fully completed questions were...

Psychosocial Work Burden of Pharmacists I.
Čavajdová, Barbora ; Švarcová, Eva (advisor) ; El-Hmoudová, Dagmar (referee)
Charles University, Faculty of Pharmacy in Hradec Králové Department Department of Social and Clinical Pharmacy Candidate Barbora Čavajdová Consultant PhDr. Eva Švarcová, Ph.D. Thesis Title Psychosocial Work Burden of Pharmacists I. Introduction: Practicing a pharmacy as a pharmacist can cause stress and strain. The main task is to dispense medicines, where a lot of attention and responsibility is needed. With the induced stress and the action of stressors, there are feelings of fatigue, which disappear after rest. Working conditions are an important factor that affect the overall mental and physical condition of the pharmacist. Objective: The aim of the work was to evaluate the degree of fatigue of pharmacists by analyzing working conditions and based on the results to recommend proposals for improving health and working conditions. Methods: The method was based on a questionnaire survey, where pharmacists responded to the degree of fatigue in the area of subjective feelings of fatigue, vision problems and problems associated with the musculoskeletal system. Questionnaires were filled in by pharmacists from chain and independent pharmacies, and the results were then compared. Out of 200 questionnaires, 160 fully completed questions were returned to me and the results were evaluated in Microsoft...

Vliv monotónní činnosti na vybrané fyziologické funkce operátorů lesnických harvestorů
Hájek, Miroslav
The characteristic feature of today's human is the ability to produce complex tools and then use them to influence their surroundings for their own benefit. Thus man constantly influences his surroundings by the activity of the world, and the energy that he makes from himself, he returns sooner or later in a different form. They are very often negative influences affecting his or her mental and health condition, which derives from the correct or gradually worsening human physiology. In this bachelor thesis, we will not only deal with selected physiological functions without which we would not survive for a long period of time, but also with the impact on these functions of monotony, which is a frequent problem of many of today's professions. In this case, we will deal with the harvester operator post.
