Multicriteria games
Tichá, Michaela ; Dlouhý, Martin (advisor) ; Lachout, Petr (referee) ; Čičková, Zuzana (referee)
Theory of multicriteria games is a special field of game theory, when one or more players have at least two payoff functions and want to maximize simultaneously. The work introduces a number of new findings. It examined the concept of finding equilibria in pure strategies in noncooperative multicriteria game. It is possible to find all the equilibria in pure strategies by full search and solving two linear programs for each point. Furthermore, two linear programs are formulated for verifying that a selected point is the equilibrium of the game or not. In the noncooperative games is also introduced the concept that with knowledge of the equilibrium of bimatrix game determines preferences of the players. Although finding the equilibrium point of the bimatrix game is nonlinear problem, finding the preferences is linear problem. The latest findings in the noncooperative games is a generalization of the concept that solves multicriteria game by assigning weights to each criterion of each player. The work demonstrates that it may not be necessarily linear weights, but it can be more general function that describes the player's preference. The remaining part is devoted to knowledge in cooperative games. There is considered that the players know their preferences and are able to express them by weights. The game with known preferences is defined and solved with the use of bargaining theory. Then it is generalized to a case where players have more payoff functions, from which they can choose. Finally, the multicriteria case of voting game is defined. It is designed completely new concept, which selects the winning coalition in the voting game. This concept is then applied to the real situation after the elections to the Chamber of Deputies in 2013.

Chosen natural resources: focuses of conflicts nad its economic consequences
Sytný, Patrik ; Vošta, Milan (advisor) ; Sankot, Ondřej (referee)
The bachelor´s thesis aims to three chosen natural resources, which are petroleum, natural gas and water, and conflicts based on disputes over them. The aim of the thesis was to valorize nature of the conflicts, define their main focus and draw prospective economic consequences. Professional literature that deals with this kind of issue, was used in order to find out the true nature of the conflicts. The result is an evaluation, which has proven, that the most influental conflicts are rising over disputes over petroleum. Their economic and political impacts are very perceptible and economically measurable in the way of GDP, the total product and other economic indicators. In the thesis has been also proven that the conflicts on the basis of natural gas have similiar nature and extent as it is in the case of petroleum, even thought in a smaller amount. The least important conflicts in a meaning of economic impacts are those over water, by those has been proven, that they do not poses such an impact on economic and political situation as petroleum or natural gas nowdays.

World Trade in Crude Oil
Benešová, Nela ; Čajka, Radek (advisor) ; Bolotov, Ilya (referee)
This master´s thesis deals with trade with crude oil and its impact on the world economy. Everyone, who wants to start to trade with crude oil, should find out basic terminology and information about crude oil that is characterized in the first chapter. The hunt for oil started many years ago, therefore the history is also mentioned in this master´s thesis. The second chapter focuses on the world trade with crude oil. Territorial structure and trade flows are described in this part of the master´s thesis. Nevertheless, the crude oil also has an impact on the world economy and economies of single states. The third chapter analyses states, where the inhabitants live beyond means of people from other countries but these states are so depended on crude oil that if this trade stopped, these countries would go bankrupt. However, there are also exceptions. Even though, there are states that have huge sources of crude oil, they still have to deal with financial problems. The forth chapter characterizes the trade with crude oil of the Czech Republic because it is a net importer of crude oil and the last chapter focuses on new trends in crude oil such as shale oil and trading at a crude oil market.

Specifics of nursing care of a child patiens with oncological pain.
ČAŇKOVÁ, Helena
The topic of the thesis is: Specifics of nursing care of a child patient with oncologic pain. Children{\crq}s pain is a phenomenon surrounded by many myths and false information. It is also not sufficiently assessed and treated and often bagatelized by both nurses and doctors. Nurses play irreplaceable role in pain treatment, they are with the child patient more frequently then the doctor and are in close touch with the child{\crq}s parents. The care of a suffering child is a serious task in nursing. Treatment of a patient in pains requires a complex, holistic approach. Nurses, even if they diagnose pain properly, do not set an adequate nursing care plan and do not carry it out. Nurses have to defend interests of the sick child and must not let him/her suffer. The data was obtained by quantitative and qualitative research. The quantitative research was carried out by the technique of anonymous questionnaire. The questionnaire was made for the parents of children with oncologic disease. The qualitative research was carried out by the technique of semi-structured in-depth interview. The research sample consisted of nurses working at the Department of children{\crq}s oncology One of the aims of this thesis was to outline the problems in nursing care of a child patient with oncologic pain from the point of view of the parents. We observed if the parents had been informed about their child{\crq}s pain, if they know what symptoms they should watch in their child, if they know all the aspects of pain to be assessed and treatment methods to relieve the pain and also how nurses respond to their child{\crq}s pain. For this aim, a following hypothesis has been set forth: The parents of children patients with oncologic pain are educated about the possibilities of nursing care focused on relieving the pain. This hypothesis was confirmed by statistic testing. Another aim of this thesis was to find out the specifics of nursing care of a child patient with oncologic pain. Nurses think that the specifics of nursing care of a child patient with oncologic pain are not different from any other care of a child in pains. They just state that an oncologic disease is associated with pains caused by the disease itself or by diagnostic or therapeutic procedures. Therefore they consider a specific feature the fact that the pain is observed more intensively and the staff is more precise in relieving the pain. It is obvious from the research that it would be effective for both parties, both for the nurses and the parents, to use educational materials on pain intended for them. I suppose that if there were such materials available, the parents would not need to contact nurses repeatedly. There was also a positive finding in the research that 92.5% of parents stated that nurses respond to children{\crq}s pain within 10 minutes. Further, that nurses believe that the child has pains, which was stated by 98.2% of the parents.

The Conclusion of a Contract under the United Nations Convention on Contracts for the International Sale of Goods in Comparison with Czech National Legislation
Krčálová, Kristýna ; Boháček, Martin (advisor) ; Levý, Jan (referee)
This Master's thesis focuses on the United Nations Convention on Contracts for the International Sale of Goods (CISG), better known as the Vienna Convention. The main purpose of this thesis is to evaluate conditions for application of this international treaty and to assess the contracting process under the CISG including the similarities and differences with the Czech national legislation. Finally, it seeks an answer to the question, which of these rules (international or national) are more advantageous for a Czech contractual party with respect to concluding a contract. The thesis is divided into five parts. The first one represents an introduction to the CISG, its origin and the Czech Republic's attitude to it. The second part identifies the conditions for application of the CISG and therefore defines a subject and an object of an international contract of sale under the CISG. Both third and fourth parts gradually introduce two phases of the contracting process (offer and acceptance) including the relevant case-law. The last chapter strives to complete the contracting process with an analysis of the exact moment, when a contract is concluded, as well as with an analysis of a potential battle of the forms and its impact on a contract conclusion.

Jakubec, František ; HOJDA, Petr (advisor) ; MIKŠ, Antonín (referee)
A Director of Photography has many artistic possibilities when working with cine lenses. Today, we can produce many optical effects in digital post-productions; however, working with lenses and with their defects (aberrations) is very interesting when you use them with modern recording technology. This thesis examines a small part of these issues. The theoretical part is about general qualities of optical systems, their aberrations, and measurement of picture quality. Furthermore, there is also a description of the movie camera and lenses, which were used for testing. The analytical part is about analyzing real footage from tests.

Sorption and Stabilization of Metals/Mettalloids by Innovative Synthesized Sorbent Amochar.
Ouředníček, P. ; Trakal, L. ; Komárek, M. ; Pohořelý, Michael
Remediation of contaminated soil which is based on stabilization and immobilization of potential\nhazardous substance by sorption materials has been studied intensively nowadays. Biochar – activated organic carbon belongs to this group of stabilizing agents which can adsorb wide range of contaminants, including metals/metalloids. Surface area of the biochars is quite large in general and functional groups (e.g. COO–) can form chelates or alkaline elements on the surface, which is represented by cation exchange capacity. Altogether with the high pH values (7.00 – 10.00), biochars are quite effective sorbents and can adsorb metals/metalloids from the solution (ground water), especially in acidic soils (in the environments affected by intensive mining activities). Sorption\neffectiveness can be increased (especially for As (V) or Cr (VI) sorption) by modification of biochar by various types of secondary oxides. Innovative sorbent AMOchar (AMO + biochar) has been synthesized currently. The product was prepared by adding of biochar to the reaction solution during amorphous manganese oxide (AMO) synthesis. The AMOchar was formed mainly by Mn-oxalates which had coated surface of the pristine biochar. AMOchar composite was able to remove significantly higher amounts of various metal(loid)s from the solution despite the rather high pH of the material. Sorption effectiveness was high not only in case of Pb (II) sorption (almost 99%), and Cd(II) (51.2%), but also a very high amount of As(V), 91.4%. Additionally, both AMOchar composite was able to reduce Mn leaching. This can avoid potential post-contamination caused by the dissolution of less stable Mn-oxalates as observed in the pure AMO.
