Recent developments and improvements of EOD program
Lencová, Bohumila
EOD is used for computations in particle optics that require accurate determination of 2D electrostatic and magnetic focusing, deflection and multipole fields and accurate evaluation of optical properties from aberration theory or from ray tracing. EOD not only allows these types of computations, but it is a complete workplace equipped with a user interface for editing input data for FEM, computation of paraxial trajectories and aberrations and ray-tracing, running the computations, producing graphical outputs and processing them. Extensive documentation on more than 500 pages gives both the user manual, theory behind FEM, optics and ray tracing and basic description of examples. The easy start in using the program is enabled by a series of PowerPoint presentations and a number of videos, showing the work with EOD on both simple and difficult examples. More than 30 projects with sample data allow the user to understand the work with EOD.

Zikmund, Marian ; Pecinovský, Rudolf (advisor) ; Suchan, Vladimír (referee)
The goal of this thesis is to design and develop a framework for building modern single- page application in the JavaScript programming language and describe this approach to development. The work also contains the documentation for a more comfortable use and customization. The content is divided into eight chapters. The introduction is followed by the retrieval of information resources, including the specifics of the JavaScript programming language and explanation of the formation of single-page application. The description of the basic principles of their functioning, motivation and justification, when and why this approach is appropriate is also included. The work is primarily focused on the issue of single-page application, for which the use of the JavaScript programming language is crucial. For this reason, this work provides a whole chapter about this programming language, also including a description of its history and role in the context of others. Below are the common characteristics of single-page applications frameworks, built on top of the library ReactJS, whose formation is engaged in the following chapter. The developed framework also contains the user guide. The practical outcome of this work is an open source framework for creating serverless single-page applications, which is due to its architecture and documentation appropriately adaptable.

Míry podobnosti pro nominální data v hierarchickém shlukování
Šulc, Zdeněk ; Řezanková, Hana (advisor) ; Šimůnek, Milan (referee) ; Žambochová, Marta (referee)
This dissertation thesis deals with similarity measures for nominal data in hierarchical clustering, which can cope with variables with more than two categories, and which aspire to replace the simple matching approach standardly used in this area. These similarity measures take into account additional characteristics of a dataset, such as frequency distribution of categories or number of categories of a given variable. The thesis recognizes three main aims. The first one is an examination and clustering performance evaluation of selected similarity measures for nominal data in hierarchical clustering of objects and variables. To achieve this goal, four experiments dealing both with the object and variable clustering were performed. They examine the clustering quality of the examined similarity measures for nominal data in comparison with the commonly used similarity measures using a binary transformation, and moreover, with several alternative methods for nominal data clustering. The comparison and evaluation are performed on real and generated datasets. Outputs of these experiments lead to knowledge, which similarity measures can generally be used, which ones perform well in a particular situation, and which ones are not recommended to use for an object or variable clustering. The second aim is to propose a theory-based similarity measure, evaluate its properties, and compare it with the other examined similarity measures. Based on this aim, two novel similarity measures, Variable Entropy and Variable Mutability are proposed; especially, the former one performs very well in datasets with a lower number of variables. The third aim of this thesis is to provide a convenient software implementation based on the examined similarity measures for nominal data, which covers the whole clustering process from a computation of a proximity matrix to evaluation of resulting clusters. This goal was also achieved by creating the nomclust package for the software R, which covers this issue, and which is freely available.

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.

Fytochemical potencial of polyfenols contain in berries
KRUMPHANZLOVÁ, Iva
This thesis sums up findings on polyphenols and their positive influence on human health. In these fytochemicals, unlike in micronutrients, recommended daily amount cannot be estimated. Micronutrient deficiency in food can cause deficiency symptoms, while in polyphenol deficiency, the deficiency does not occur. When they are present in sufficient amount in food, it is considered functional food, which is important for civilization illnesses prevention. At the beginning of the theoretical part, the polyphenol classification from pharmacological and chemical point of view is represented. On the basis of this classification important role of antioxidants and flavonoids is described. Special attention is being paid to resveratrol, which is populardue to its well known "French paradox". The following part considers the polyphenol influence on human health. The way in which polyphenols protect our body from certain diseases is explained in detail. Most of the health benefits are supported by studies conducted on animals. These studies are also mentioned and described in this paper. In the theoretical part the process of absorption and the polyphenols safety for human body is also explained. Polyphenol sources are listed in the last subchapter. The work is mainly aimed at blueberry fruits (Vaccinium myrtillus) and vine grapes (Vitis vinifera). Other berries are briefly mentioned as well, such as cranberries, raspberries, blackberries and currant. The goal of this work is to create a diet that would provide a functional daily amount of polyphenols. This amount can be compared to 120 ml of native blueberries. Only products, consumable without cooking, are used in this diet. The second goal is to chart, which food products are adequate source of polyphenols. On the basis of these goals, research inquiries were defined. Research inquiry No. 1: What amount of polyphenols is contained in berries, especially blueberries. Research inquiry No. 2: Which food products (without cooking) are ideal to be included in diet, to provide adequate daily amount of polyphenols. To asses polyphenol content in blueberries, analysis of polyphenol content acquired through GEOMED program from Nemocnice České Budějovice a.s., department of clinical pharmacology, was used. Assessments were made using the HPLC method (high performance liquid chromatography) in cooperation with the biological centre AV ČR in České Budějovice. Thanks to this analysis, the first inquiry can be answered. An interesting phenomenon is discovered, that frozen blueberries have higher polyphenol content then cooled ones. Malvidin (malvidin-3-6"-acetoyl glycoside) was chosen as priority anthocyan since it is most represented in the blueberry. Remaining information about polyphenol content in certain food products were drawn on Joseph Maroon´s book, MD, FACS (2010). The practical part involves a diet for 14 days, which meets the given requirements. The results clearly show that it is possible to create a diet rich in polyphenols. A list of blueberry products accessible to everyone is included. Blueberry dairy products, jams, beverages, fruit salads and fruit pyre have been analysed. The list shows which product contains the most polyphenols. The required amount can be achieved by the proper combination of given products. The ideal one proved to be 200 ml of red wine and one blueberry dairy product (with the malvidin value higher than 64). Findings in this paper will serve to promote polyphenol awareness and itseffects. This diet can be used in nursing homes, where their positive influence on equilibrium can be applied. It can also be used in spas and other alimentation related facilities.

Antidecubital Care as a Nursing Problem
KŘÍŽOVÁ, Monika
This thesis deals with the issue of providing antidecubital care and observes the fulfilment of nursing interventions in the care about non-self sufficient patients. During performing her duties, every nurse encounters the issue of decubitus ulcers formation and with this related antidecubital care. Thus, it can be stated that the occurrence of decubitous ulcers serves also as the indicator of the quality of provided nursing care. A lot of people think that the problem develops particularly in elders, but young people who are bedridden after injuries and accidents are also affected and this complication degrades the quality of their life. The thesis is divided into theoretical and empirical parts. The theoretical part describes the anatomy of skin and its function, decubitus and classification of decubitus ulcers are defined, their localization with characteristics of predilection sites are specified, outlining complications in decubitus ulcers. The theoretical part pursues antidecubital care with the division into subheads on positioning, antidecubital aids, nursing interventions, and the mission of the European Pressure Ulcer Advisory Panel is described. The separate chapter includes the risk assessment of decubitus ulcers formations, as is e.g. Norton scale, etc. The last chapter embraces the specification of conservative and surgical treatment of pressure sores. The aim of the research examination was to determine whether the nurses perceived antidecubital care as a nursing problem and to map the opinions of the nurses relating to antidecubital care. Three research questions were set to achieve the objectives: first, what the pitfalls of nursing care were on the part of the nurses, secondly, what areas within antidecubital care were neglected and finally, how antidecubital care at selected inpatient wards was provided. The research was implemented at the chosen inpatient wards in České Budějovice Hospital, PLC, from the period of February to April 2014. The research file consisted of the general nurses and the medical assistants. A hidden participant observation was conducted and then questionnaires with 15 questions that were closed or semi-closed were distributed to the nurses. 45 questionnaires were handed out, 31 handed back and all 31 questionnaires could be processed. Thus, the total return of the questionnaires was 69%. Questions in the questionnaire were based on the observation criteria. The hidden participant observation was processed and plotted on the observation sheet and then classified according to the given criteria. After delivery, the returned questionnaires were checked and evaluated graphically. All results were processed using Misrocoft Office Excel program, were plotted in graphs with keys and descriptions. By processing and comparing the results, we ascertained that in some fields the opinion of the nurses was different from the practice that was really performed. It could be also caused by the fact that antidecubital care is very time-consuming, demanding and comprises a lot of nursing interventions. Sufficient number of aids with which the ward is equipped is relevant as well, be it preventive aids or medical ones. And last but not least the organization of the care. At present, the time spent on completing documentation is increasing and the time that can be used by nurses for contacting a patient and satisfy his/her needs is decreasing. Nevertheless, the patient´s state and his/her contentment reflect and demonstrate our care. After previous arrangement, the results of our research examination will be communicated to the ward sisters at the selected inpatient wards where the research examination was performed.
