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.

How are high school students informed about virus biology
Solarová, Pavlína ; Drda Morávková, Alena (advisor) ; Fraiberk, Martin (referee)
Biology is the study of viruses, which are engaged in teaching 2-3 lessons. During those hours, students must not only absorb information about the structure and function of the virus, but also the reproduction of the organism, several representatives and, ultimately, diseases that cause that exists prevention and treatment these diseases. Students remember what it is for the vaccine, the virus infects whom, how they can get infected or what the immune system. What makes the problem of students are questions: which of the viral disease is, what constitutes a viral particle, or what is an infectious disease. In the RVP G is determined curriculum is very vaguely. The teacher thus has a certain freedom in creating the ŠVP and its preparations. To more precise what students should know for graduation, testing requirements used common catalog of the school-leaving examination in this case of biology, who has broken the outputs of the curriculum of all biological disciplines.

The nutritional importance of polyphenols in berries
MARTANOVÁ, Anna
People's nutrition is inseparable part of our lives. We could include substances, that we know are healtful, to our food. If we don't have enough of the substances, we can see negative effects on human organism. The substances are named micronutrients and vitamins. We could enrich a diet with substances that we think are healthy, but their deficit doesn't case pathological symptoms. Food which we put to this category is possible to name as function food. Function food contains substances which have positive effect on our health. One of the substances are polyphenols. This issue is very interesting for me, because polyphenols are compounds that are among others particulary found in berries, especially in blueberries. Blueberries are berries that are widespread throughout the world. One of the best sources of blueberries is also Sumava, where I come from and where blueberries are well connected. The first part of my thesis is about the functional foods and ingredients that make these foods Functional foods. Ordering: probiotics, prebiotics, synobiotiks, micronutrients, fytochemiks and polyphenols. Farther the first part deals with berries, specializing in blueberry and its properties and composition, which can have a positive impact on human health.In the second part there were two objectives of the work. The first aim of my study was to determine the diet, which includes foods that contain the optimum intake of polyphenols, equivalent to 120 ml of fetal native blueberries. Polyphenols are that part of blueberries, which make them so special. In the diet were preferentially embedded short dishes that have undergone heat treatment. Analyses of polyphenols in foods and beverages I got with the program GEOMED hospital Ceske Budejovice, Inc., Department of Clinical Pharmacology. Results polyphenol content were performed by HPLC. The content of polyphenols in native blueberries was laid as equal to 1 and the contents examined further product was then expressed as a multiple or ratio of the native blueberries. I take into account all these factors when drawing up the model menu. Another aim I have set is to map products in which the content of polyphenol is beneficial. There is a high number of products with blueberry flavour on the market. The content of blueberries, however, is often negligible. The surprising result was the polyphenol content in lemonade Toma, whose relative value ug / ml is 2.59 when compared with the native blueberry, which is placed as equal to 1. After the development work, in which I obtained information from the literature search, the sales network and the Department of Clinical Pharmacology, Hospital Ceske Budejovice, I would like to say that blueberries are an important source of polyphenols and that a diet which will include daily equivalent of receiving polyphenols, may not in any way differ from a regular rational diet. Not even cooking the dish precludes putting together this diet because blueberries are relatively stable against temperature changes. Inclusion of such a diet in the catering equipment could bring a positive impact in the future, especially for older people by improving memory function and balance.

Podnikatelský plán vybrané firmy (model lean canvas)
Strupplová, Lucie ; Filipová, Alena (advisor) ; Zeman, Jiří (referee)
The well arranged and instructivee business plan is the basic part of every business project.. Currently is very often used the lean canvas model of the business plan. This model shows us very istructively all the factors influencing the project realisation. The dissertation is divided into the two basic parts. In the thoretical were compared the essential forms of the business plan with their differences. The practical part consists of creating the lean canvas model for the progressive company using the UAV and the MAIA application, monitoring the flight of the UAV. The economic data were analyzed and the structured scheme of the project, with the prediction was realized. The lean canvas model was very useful and optimal for this company and it´s project.

Výběr a implementace open source nástroje pro řízení portfolia projektů
Marek, Jan ; Chlapek, Dušan (advisor) ; Kučera, Jan (referee)
Methods and ways of implementation of changes and innovations in companies through project management are in today's society very well established. There exists methodologies, techniques and tools for the management of individual projects. However in a role of project manager, I very often faced the fact that companies are performing the project portfolio management in very intuitive way. This in itself leads to failed and prematurely terminated projects, initiation of the wrong projects or realisation of correct projects, but at the wrong time. Very often I have also recognized, that there is lack of awareness of fact, that there are also Open Source applications that can help with the organization's portfolio. This thesis deals with the definition of requirements, search and selection of proper OSS application and subsequent implementation. In the first part of this thesis I prepare a theoretical framework about PPM, and on that basis then identify and verify a set of requirements for selection of right OSS PPM application. The next section of thesis describes searching for suitable applications from a variety of sources, assessment against the requirements and the final selection. In the last part the implementation project is drafted, which aims to serve other colleagues in project management as one of the possible implementation paths. The outputs are then continuously confronted with experts in matter of projects and project management in the field of IT in order to maximize symbiosis between theory and real life experiences. Virtually every project management methodology defines the collection of already-proven techniques, best practices or lessons learned from the previous similar implementations. The main contribution of this thesis I see in fact that it contains not only the design of the project implementation, but also describes a logical path, what leads to the result. Therefore this thesis could be used as a base or discussed best practice, when a project of implementation of PPM application in place.

The tax system reduces motivation to return to work among mothers with young children: recommendations and evaluation
Šatava, Jiří
In the Czech Republic, the overall taxation of work, i.e individuals' income tax together with social security and health insurance contributions, places a heavy burden even on the relatively low earnings of so-called second earners in households, i.e. partners with lower earnings. These peoples' work activity is, however, generally very sensitive to the level of taxation. A large group of these earners is made up of mothers with young children. Mothers who are the second earner in their household are subject to a participation tax rate (PTR) up to 30 % higher than their partners, and yet a higher PTR results in lower motivation to work. Women with children and low earning potential are subjected to the highest PTRs in comparison with their partners.

Access to Information and Access to Justice in Environmental Matters in the Republic of Irealand and the Czech Republic
Vítková, Martina ; Stejskal, Vojtěch (advisor) ; Sobotka, Michal (referee)
This diploma thesis deals with access to environmental information and access to justice in environmental matters introduced by Aarhus Convention in the specific conditions of Czech Republic and Ireland. These rights are considered to be very important tools for environmental protection. At a time when people threaten their own existence by negative interference with the environment it is necessary that effective means for its protection exist. These means are access to environmental information and access to justice in environmental matters, which together can be called as environmental procedural rights. The first chapter of this thesis presents the sources of environmental procedural law and observes the development of law at international, European and national level. The most important international document in this field is the Aarhus Convention that was adopted in 1998 by most of the European countries and that provides for access to environmental information, access to justice and public participation in environmental decision-making. This convention has largely affected the law of the European Union, where several directives has been adopted, including most importantly the Directive 2003/4/EC on access to environmental information and the Directive 2003/35/EC on public participation in...

Introduction to bio art
Šperanda, Nina ; SILVERIO, Robert (advisor) ; JANOŠČÍK, Václav (referee)
Bio art is a contemporary art practice that works with living organisms (except humans) or is created in cooperation with living organisms. It is relatively new art movement that is rooted deeply inside the history of evolution, domestication of animals and plants, technological discoveries, their development and science. Never before was art questioning its ethics and aesthetics in such profound, molecular and sub-molecular way.
In this work I will consider the historical influences and conditions that led to current developments in the field. I will also try to explain the problematics of defining what bio art is and try to clarify the associated terminology. Most relevant and ground breaking works in the field will be mentioned as some new recent developments.
Aesthetics of bio art is also an important subject often set aside by the ado around ethics of it. It is an extremely important subject to be considered when talking about bio art and I will try to sketch out a brief outline of it with references to philosophy and contemporary bio art theory.

Šimon, Lukáš ; VIZVÁRY, Radim (advisor) ; SOPROVÁ, Jana (referee)
This thesis discusses the life and work of Etienne Decroux, one of France's most important reformers of the theater and his method of Le Mime Corporel, which still forms the basis of modern pantomime. Decroux is known worldwide as an excellent mime, director, teacher, theorist and reformer of the theater. His contribution to the development of the European theater in the last century is very significant, especially for mime theatre. The work presents Decroux's personality and his contribution to the creation of the new method of mime theatre - Le Mime Corporel. Another task of this thesis is to explore the effects of different important personalities in the artistic development of Etienne Decroux, to describe the basic elements forming the method Le Mime Corporel and to compare it to other genres of movement theater.
