Henzl, Martin ; Rosa, Tomáš (referee) ; Staudek, Jan (referee) ; Hanáček, Petr (advisor)
Tato práce analyzuje hrozby pro protokoly využívající bezkontaktní čipové karty a představuje metodu pro poloautomatické hledání zranitelností v takových protokolech pomocí model checkingu. Návrh a implementace bezpečných aplikací jsou obtížné úkoly, i když je použit bezpečný hardware. Specifikace na vysoké úrovni abstrakce může vést k různým implementacím. Je důležité používat čipovou kartu správně, nevhodná implementace protokolu může přinést zranitelnosti, i když je protokol sám o sobě bezpečný. Cílem této práce je poskytnout metodu, která může být využita vývojáři protokolů k vytvoření modelu libovolné čipové karty, se zaměřením na bezkontaktní čipové karty, k vytvoření modelu protokolu a k použití model checkingu pro nalezení útoků v tomto modelu. Útok může být následně proveden a pokud není úspěšný, model je upraven pro další běh model checkingu. Pro formální verifikaci byla použita platforma AVANTSSAR, modely jsou psány v jazyce ASLan++. Jsou poskytnuty příklady pro demonstraci použitelnosti navrhované metody. Tato metoda byla použita k nalezení slabiny bezkontaktní čipové karty Mifare DESFire. Tato práce se dále zabývá hrozbami, které není možné pokrýt navrhovanou metodou, jako jsou útoky relay.

Effective using of potential of bilingual environment
HOVORKOVÁ, Eva
The dissertation thesis "How to use the potential of bilingual environment efficiently" endeavors to highlight bad as well as good practices in bilingual upbringing. Bilingualism represents at present a very topical issue. In connection with increasing globalization, the issue of learning of foreign languages is more and more emphasised. People living in mixed marriages have often no idea how to bring their children up. In many cases they take steps that lead to irreversible consequences. The theoretical part of the thesis gives a survey of bilingualism, the division and kinds of bilingualism and ways of its acquisiton. The theory is practically illustrated in the empirical part through various examples. 42 case studies have been carried out, which include characteristic and uncharacteristic respondents. The findings of the research are compared with the facts mentioned in the reference works. The aim of the dissertation thesis is to find out which educational methods should parents follow in bilingual education and which methods they should better avoid.

THE DRAMATICAL SCRIPT AS A NECESSARY BASIS FOR SPACIAL REALIZATOIN
Tretiag, Štěpán ; KORČÁK, Jakub (advisor) ; HRBEK, Daniel (referee)
Using the concrete examples of my practical bachelor work my intent is to retrospectively describe and reflect on our scenic realization of the play Missing by south-African author Reza de Wet. The essence of a modern dramatic direction is to perceive the script of a play as a model which becomes a basis for its interpretation and the subsequent staging of the play. It is the process from the initial interpretation to final scenic realization I wish to focus on in my work.In the first part I will be dealing with creation of a physical space, that being stage design. I will try to capture what lead us to its final shape and how the basis for that can be found in the script of the play as well as the potential capability of the physical space to become a dramatic space. Its ability to create a platform for the actors to proceed from and how can it provoke them into acting, in particular. In the second part I will be dealing with the dramatic space, ergo the spacial expression of relationships and themes. I will proceed again retrospectively, focusing on how we managed to achieve the stage image which is functioning as a materialized metaphor. I will focus mostly on non-verbal actions, but with regard to the fact, that dramatical script is the basis for our realization of the play.

Obesity in children of school age from the perspective of nurses working in GP
BURSÍKOVÁ, Drahoslava
Abstract Obesity in School Children from the Point of View of a Nurse Working in a GP's Surgery The thesis focuses on the problems of nursing care of children with overweight and obesity. This issue is very urgent nowadays, not only in the Czech Republic, but it is a global problem. Our country holds one of the leading positions in children obesity. Children suffering from overweight and obesity have not only health problems resulting from obesity complications, but also problems in the field of psyche and social relations, particularly among their peers. This is why the right insight into the issue and finding an acceptable solution for the future is so important. The theoretical part deals with the problems of children obesity, the specifics of nursing care of these children within a surgery of a general paediatrician. It also focuses on the needs of children with normal weight and on the needs of overweight children. Four aims were set within the research. The first aim was to map the situation in obesity among school and pre-school children in Benešov District. The second aim was to map services (possibilities of further assistance, treatment) that parents and practitioners may use in treatment of children with overweight and obesity in Benešov District. The third aim was to compare success rate of obesity treatment in children that have already undergone obesity treatment under specialist supervision and success rate of weight reduction in children trying themselves. The fourth aim was to map the problems of cooperation of a nurse with parents and school in treatment of a child with obesity. We used a qualitative research method in the research part of the thesis. The questioning method by means of semi structured interview was applied. Three research samples were prepared for the research purposes. The first research sample consisted of 10 nurses working in paediatrician practitioner surgeries in Benešov District. The second research sample consisted of 10 persons intentionally chosen from among parents of children with obesity that are trying to reduce the weight of their children themselves or under assistance of an obesity specialist. The children were of school and pre-school age. The third research sample consisted of 10 paediatrician practitioners practicing in Benešov District. Open-coding technique paper and pencil method was applied on interview processing. A document analysis was used for the mapping of the services in Benešov District and the whole Central Bohemia Region. Six research questions were set: 1. What are the possibilities of specialist help to obese children? 2. Are parents willing to help their obese children with overweight reduction? 3. Do parents of obese children also have problems with overweight? 4. What experience do nurses from paediatrician practitioner surgeries have with care about obese children? 5. What does cooperation between parents and a nurse from a paediatrician practitioner surgery looks like? 6. How does a nurse working in a paediatrician practitioner's surgery cooperates with the school? The thesis conclusion shows that the problem of children obesity is not just the matter of Benešov District, but it is a global problem, it is urgent and has an increasing trend.

Doped DLC coatings for biomedical applications
Písařík, Petr
Nowadays there are materials having excellent properties for use in medicine (Diamond-like carbon, Hydroxyapatite, …). Diamond-like carbon (DLC) is a metastable form of amorphous carbon containing bonded carbon atoms of sp2 and sp3 hybridized orbital. DLC layers are semiconductors with high mechanical hardness, chemical inertness, low coefficient of friction, high thermal conductivity, good electrical and optical properties, biocompatibility and no cytotoxicity. All properties of the films are not always ideal, so it is necessary to modify the layer. One example of how to modify the properties of thin layers are dopations. The incorporation of dopants in films may lead to greater multifunctionality and much improved properties. Most modifications were made to modify contact angle and surface energy, to reduce internal stresses, to decrease surface roughness, coefficient of friction or wear....

Estrogen receptor beta (ERβ) in testicular cells and sperm
Dostálová, Pavla ; Žatecká, Eva ; Děd, Lukáš ; Dorosh, Andriy ; Postlerová, Pavla ; Jonáková, Věra ; Dvořáková-Hortová, Kateřina ; Pěknicová, Jana
Estrogen is a steroid hormone that plays an important role during sperm development in the male and female reproductive tract. Estrogen signalling is a complex process that depends on cell milieu and presence of receptors. Thanks to the steroid nature of estrogens, they can pass through the plasmatic membrane and bind to the intracellular estrogen receptors (ERs). Within the cell, there are several pools of ERs. One of them is localized to the cell nucleus and their activation leads to direct or indirect binding to DNA and ultimately to alternation in gene expression (genomic pathway). Other pools of ERs are associated with plasma membrane or are located in cytosol. Activation of membrane associated ERs leads to rapid non-genomic responses. Nowadays, two classical estrogen receptors are known – ERα and ERβ. Since ERβ is a predominant variant in testes, we focused our study on expression of ERβ variants in murine testes and sperm. We detected two variants of ERβ at mRNA level in both, testes and sperm. These variants differ in 54 nucleotids within the ligand binding domain and this variability results in different affinity to estrogen. We analyzed individual testicular cell types (spermatogonia, spermatocytes, spermatids, Sertoli cells) by RT-qPCR. Our results suggest that both ERβ variants are coexpressed in the same cell type and may therefore interact together. This may have consequences in mediating of estrogen signalling. Moreover, ERβ is expressed more in the later stages of spermatogenesis suggesting the role of ERβ in these stages or alternatively in spermatozoa alone. At the protein level, we detected ERβ in nuclear, membrane and cytosolic fraction prepared from testicular tissue suggesting the involvement of both, genomic and non-genomic, pathways of estrogen signaling in testes. In sperm, anti-ERβ antibodies localized ERβ in acrosome region and tail which is in accordance with the known role of estrogen on capacitation, acrosome reaction and motility.
