Klíma, Tomáš ; Doucek, Petr (advisor) ; Čermák, Igor (referee) ; Čapek, Jan (referee) ; Štubňa, Ivan (referee)
The aim of this dissertation thesis is to develop new methodology of information systems penetration testing based on analysis of current methodologies and the role of penetration tests in context of IS/IT governance. Integral part of this aim is evaluation of the methodology. The first part of the thesis is devoted to the presentation of history and current state of research in selected area, definiton of basic terms and introduction of role of the penetration tests. This part is followed by the review of relevant sources and comparative study of current methodologies with a goal to identify their weaknesses. Results from this study are further used as a basis for new methodology development. Classification of IS penetration tests types and testing scenarios are also included. The second part includes design of new methodology, at first its history, structure and principles are presented, then its framework is decribed in high level of detail. In the third part the reader can find (theoretical and practical) validation. The biggest scientific contribution is the methodology itself focused on managment of penetration tests (which is the area currently not sufficiently descibed). Secondary contribution is the extensive review and the comparative analysis of current methodologies. Contribution to the economic and technical (practical) application we can mainly see in the development of new methodology which enables companies to improve management of penetration tests (especially planning, operational management and implementation of countermeasures).

Use of Interest Rate Models for Interest Rate Risk Management in the Czech Financial Market Environment
Cíchová Králová, Dana ; Arlt, Josef (advisor) ; Cipra, Tomáš (referee) ; Witzany, Jiří (referee)
The main goal of this thesis is to suggest an appropriate approach to interest rate risk modeling in the Czech financial market environment in various situations. Three distinct periods are analyzed. These periods, which are the period before the global financial crisis, period during the financial crisis and in the aftermath of the global financial crisis and calming subsequent debt crisis in the eurozone, are characterized by different evaluation of liquidity and credit risk, different relationship between financial variables and market participants and different degree of market regulations. Within this goal, an application of the BGM model in the Czech financial market environment is crucial. Use of the BGM model for the purpose of predicting a dynamics of a yield curve is not very common. This is firstly due to the fact that primary use of this model is a valuation of interest rate derivatives while ensuring the absence of arbitrage and secondly its application is relatively difficult. Nevertheless, I apply the BGM model to obtain predictions of the probability distributions of interest rates in the Czech and eurozone market environment, because its complexity, direct modeling of a yield curve based on market rates and especially a possibility of parameter estimation based on current swaptions volatilities quotations may lead to a significant improvement of predictions. This improvement was also confirmed in this thesis. Use of swaptions volatilities market quotations is especially useful in the period of unprecedented mone- tary easing and increased number of central banks and other regulators interventions into financial markets that occur after the financial crisis, because it reflects current market expectations which also include future interventions. As a consequence of underdevelopment of the Czech financial market there are no market quotations of Czech koruna denominated swaptions volatilities. I suggest their approximations based on quotations of euro denominated swaptions volatilities and also using volatilities of koruna and euro forward rates. Use of this approach ensures that predictions of the Czech yield curve dynamics contain current market expectations. To my knowledge, any other author has not presented similar application of the BGM model in the Czech financial market environment. In this thesis I further predict a Czech and Euro area money market yield curve dynamics using the CIR and the GP models as representatives of various types of interest rates models to compare these predictions with BGM predictions. I suggest a comprehensive system of three criteria, based on comparison of predicti- ons with reality, to describe a predictive power of selected models and an appropria- teness of their use in the Czech market environment during different situations in the market. This analysis shows that predictions of the Czech money market yield curve dynamics based on the BGM model demonstrate high predictive power and the best 8 quality in comparison with other models. GP model also produces relatively good qua- lity predictions. Conversely, predictions based on the CIR model as a representative of short rate model family completely failed when describing reality. In a situation when the economy allows negative rates and there is simultaneously a significant likelihood of their implementation, I recommend to obtain predictions of Czech money market yield curve dynamics using GP model which allows existence of negative interest rates. This analysis also contains a statistical test for validating the predictive power of each model and information on other tests. Berkowitz test rejects a hypothesis of accurate predictions for each model. However, this fact is common in real data testing even when using relatively good model. This fact is especially caused by difficult fulfilment of test conditions in real world. To my knowledge, such an analysis of the predictive power of selected interest rate models moreover in the Czech financial market environment has not been published yet. The last goal of this thesis is to suggest an appropriate approach to obtaining pre- dictions of Czech government bonds risk premium dynamics. I define this risk premium as a difference between government bond yields and fixed rate of CZK IRS with the same length. I apply the GP model to describe the dynamics of this indicator of the Czech Republic credit risk. In order to obtain a time series of the risk premium which are necessary for estimation of GP model parameters I firstly estimate yield curves of Czech government bonds using Svensson model for each trading day since 2005. Resulting si- mulations of risk premium show that the GP model predicts the real development of risk premiums of all maturities relatively well. Hence, the proposed approach is suitable for modeling of Czech Republic credit risk based on the use of information extracted from financial markets. I have not registered proposed approach to risk premium modeling moreover in the Czech financial market environment in other publications.

The Role of Nurse in the Prevention of Disease of Civilisation
PAVLOVÁ, Martina
The current state Prevention is a complex care of a patient when we are trying to prevent from the occurrence or development of a disease, or when we want to prevent from its consequences and mitigate them. Recommendations for prevention set by a doctor must be on a scientific basis, and they must be a part of all branches of medicine. Their effectiveness depends on the cooperation between patients and medical staff. The basic and most efficient method of prevention is the health promotion and health education, which is closely associated with it. The term health promotion involves a set of activities and precautions for the purpose of making health better and sustaining it. Diseases of civilisation (hereinafter "DoC") are groups of diseases which are distinguished by their association to our lifestyles. Human body is more and more threatened from unfavourable influences of external environment, such as the quality of atmosphere, work environment and environment itself, the lack of physical movement, unhealthy diet, smoking, and alcohol consumption. The list of diseases of civilisation varies and changes together with our society and the development of our lifestyles. Among the most common or frequent diseases of current time are cardiovascular diseases, which involve atherosclerosis, hypertension, myocardial infarction, stroke, coronary artery disease and obesity. Furthermore, between civilization diseases include diabetes mellitus type 2 or cancer, etc. The goal of the thesis There are two goals set for this paper. The first goal was to find out what the role of a nurse in the prevention of diseases of civilisation was. The second goal was to find out what the above mentioned role of a nurse was from the point of view of patients. Methodology For the purpose of the research part of this thesis, qualitative research using semistructured interviews was carried out. Respondents were divided into two groups; the first one consisted of eight nurses working at internal medicine and neurological department of the hospital in České Budějovice and a nurse working in a private office of a general practitioner for adult patients. The second group consisted of eight patients of the above mentioned health facilities. Results According to our findings, nurses and patients have different oppinions on the role of a nurse. Nurses in disease prevention see themselves as an equivalent to a doctor when undertaking this practice and giving guidance. The patient speaks only to the nurse who emphasized what they were told by the doctor and reiterated the main points. They make available to them leaflets and brochures or Internet resources. In contrast, most patients see a nurse as a more important source of information than the doctor. Patients have the feeling that the doctor does not have enough time or does not want to be botherd with questions. Rather the patient turns to his nurse, which they sees as more appropriate and someone to whom they can confide in without bothering. Summary The goal of the thesis was to focus on prevention, DoC, and the role of a nurse in the prevention of such diseases, as well as to study this issue, look at it from the point of view of patients and nurses via the interviews carried out in this paper, and to analyse such information. Based on this analysis are published recommendations for nurses and patients.

Pick´s disease and the specifics of the nursing care of a patient with this disease
KOPKAŠOVÁ, Lenka
Pick's disease is a degenerative-atrophic process that primarily affects the frontal and temporal lobes of the brain. Besides Alzheimer's disease, it is a lesser known form of dementia which affects people of younger age. Although the exact range of Pick's disease occurrence varies in the literature, the average reported age is between 50-60 years. The disease can change eating habits, cause emotional swings, inappropriate behaviour and sloppy appearance of the patients. The behaviour to others is often selfish, the patients are unable to listen to others and ignore their surroundings. Pick's disease is also characterized by inappropriate sexual behaviour. Globally, the number of dementia patients is still growing and according to expert guesses the increase will continue. Nursing care for patients with dementia is therefore becoming a very actual topic as dementia is called a quiet epidemic of our century. Nurses in their departments quite frequently encounter patients suffering from dementia of various origins at different stages of disability and the staff at healthcare facilities often regard these people as a burden. The aim of this thesis, which is called Pick's Disease and Specifics of Nursing Care for Patients with this Disease, is, based on the theoretical knowledge, to map definitions and diagnosis of Pick's disease, to define the needs of such a patient, and to list the most common problems in the nursing care. It focuses on people with dementia within medical facilities. For proper understanding of the problem, the thesis starts with the anatomy and physiology of the brain and the description of cognitive functions which are affected by the dementia syndrome and the definition of dementia. Based on the studied literature, dementia is divided according to various criteria. It has been found out that dividing dementia is not entirely uniform, but the essential facts and overall opinions of the authors do not diverge. Pick's disease belongs to a group of frontotemporal dementia and its position in this group has changed over time, as it is recorded in the literature. The thesis includes recommendations resulting from the studied literature in the approach to patients with dementia and emphasizes personal communication with the patients and empathetic and humane approach. Although medicine cannot prevent dementia, an early diagnosis of a specific type of dementia and correctly targeted treatment can increase the quality of life not only of the patients but also of their families. I have chosen this topic because I find it very current and interesting. During my nursing practice at the Surgery Department and Aftercare Department, I have met patients suffering from dementia and I did not know how to properly and efficiently communicate with them. For the theoretical part of my work, the methods of explanation, synthesis and induction on the basis of Czech and foreign information sources have been used. The most frequently quoted Czech authors in my thesis are doc. MD. Roman Jirák, PhD., the head of the center for diagnosis and therapy of Alzheimer's disease at the psychiatric clinic of the General University Hospital in Prague, the 1st Medical Faculty of Charles University. This thesis can serve as an informational and educational source both for nurses and the general public who may experience the disease within their families. It would be considered a great success if it helped nurses or family members to diagnose Pick's disease or other dementia at an early stage.

Relationship between the coat colour and melanoma occurrence in horses
Hovorková, Kristýna ; Hofmanová, Barbora (advisor) ; Majzlík, Ivan (referee)
The literary review is divided into two main parts, the first part is dealing with the coloring of horses and their genetic base and the second part is dealing with melanoma formations of horses and their division. In the chapter about several color types of horses there is a description of forming basic color types which is done by three locuses: COLOR, EXTENSION and AGOUTI. Locus COLOR (CREAM) controls whether or not to create pigment. EXTENSION locus controls about the type of pigment and AGOUTI locus controls the distribution of pigment.
The next subsection gives a breakdown of the white color in horses. Greying proces is related with locus GREY where there is a loss of pigment and the coat itself. This process and mutation is commonly connected with dermal melanoma. Non-pigmented spots called vtiligos are connected with the greying process, which is more intense with increasing age. Vtiligios are commonly found in grey horses, at the same locations as dermal melanoma. The places are perianal area under the tail, around the vulva, lips, eyes and around the penis.
Melanoma formations are divided according to whether they occur in Grey horses or other colored horses and whether they have a benign or malignant potential. A further breakdown of melanomas at grey horses is whether it is a separate, smaller segments or large, associated lesions, when this condition is called dermal melanomatosis.
At the end of the thesis there is a description of the treatment options for melanoma. The most effective appears to be a surgical removal of smaller formations. There were studies which have examined the anticancer action of the drug cimetidine but the results are not yet sufficiently conclusive. As preventing the occurrence of melanoma in grey horses it is appropriate to implement the necessary measures and individuals who are concerned should not be included in the next breeding.

The renovation of historical parks near the small feudal residences on the example of the study of the renovation of the castle garden in Doudleby nad Orlici in Eastern Bohemia.
Faltysová, Lenka ; Buttry, Ivana (advisor) ; Jakub, Jakub (referee)
The aim of this work is the processing methodology and presentation process how to restore monuments of garden art. On the example of the revitalization of the castle garden immovable cultural monument Castle Doudleby nad Orlicí, based on the study of literature, similar interventions and the analysis and interpretation of various types of archival material the current quality of historic garden was evaluated. It is based on field survey, which consists of dendrological research, analyzing the authenticity of trees and appreciation of all the collected documents, historical sources and professional literature. Concept recovery of castle garden is based on the expert authority´s binding point of view of the state care of historical monuments.
Renaissance castle in Doudleby nad Orlici is located in the eastern part of the town on a slightly raised hill on the right bank of the River Divoká Orlice. There was a wooden medieval fortress with the farmyard on this place in the 13th century. Sr Mikuláš from Bubno started to build a hunting lodge in the Renaissance style as villa in 1588, which was finished in 1590. The significance of Renaissance residence, which complement the early Baroque elements from the late 17th century, is enhanced by the opulent and impressive sgraffito - carpet pattern covering all external and internal frontage, restored in 1886 by Kirchner. The tall chimneys are the part of decoration in the courtyard decorated with sgraffito as well. The chateau complex is formed along its circuit of farm buildings and residential buildings. Building of castle itself is separated by a park with old trees and newer lawns (Hieke, 1984).
Castle park in Doudleby nad Orlicí was founded in 1809 in compositional continuity of the Renaissance castle building. The park forms one organic complex with the castle. The promoter strived, like in the castle rooms, to demonstrate here his wealth, his sense of art and his botanical-dendrological knowledge. The park is designed as a narrow disposition in landscape style and it is composed as a long vista to the castle. The area of the landscape park is 3.76 hectares nowadays.
The literature search is especially dedicated to the Renaissance and its relationship to the garden art. The monument care in the Czech Republic and the activity of professional organization of the monument care of the National Heritage Institute in Josefov is introduced in this section.
The methodological guide describes the used bolsterings and resulting outputs on the basis of them are implemented of such measures, which will help to improve the health and vitality of existing promising trees and new plantings of trees, which are consistent with the original composition with emphasis on the rehabilitation and upgrading of historical value of the object. Treatment of trees and supplementary planting will be done within the frame of total revitalization of the castle park.
The practical unit describes the current status of vegetation monuments of garden art. The inventory trees is the essential tool for analyzing the current status of vegetation monuments of garden art. Inventory, which should provide quality base for a draft recovery, should also be addressed in certain parts with characteristics of individual species (Krejčiřík, 2015).
The results of field investigation were completely recorded in the graphical output.

Resolving of insolvency of business corporations trough bankruptcy
Marková, Martina ; Civínová, Denisa (advisor) ; Klára, Klára (referee)
The presented thesis tries to introduce the reader to the course of the insolvency proceedings, especially in bankruptcy proceedings. The theoretical part mainly discussed about the meaning and history of this institute, further aspects necessary for the commencement of insolvency proceedings and then there is described in more concise form the additional course up to the decision on the debtors bankruptcy. Subsequently, the author deals with the consequent procedure in cases where the debtors bankruptcy is solved by bankruptcy. Describes the course, focusing primarily on the sale of the debtors property and its subsequent allocation among the creditors until its conclusion, which is the submission of the final report by the insolvency administrator of the court, its subsequent approval and distribution schedule. In the practical part of the thesis the theoretical knowledge mentioned above is applied to the selected insolvency case of business corporation. In this part there are also pointed some potential problems and complexities that arose in this case. There is also described and analyzed the entire insolvency proceedings from filing an insolvency petition to the preparation of the final report by the insolvency administrator, that is the stage where the proceedings took place on the date of submission of this work. Furthermore, the author discusses the development and the number of insolvency proceedings in our country since 2008 when the new legislation of this institute came into force. On the same principle, the author also deals with the analysis of the most common types of obligations of business corporations.

Change trajectories of wetlands in the landscape of lowlands and uplands in the Czech Republic
Richter, Pavel ; Skaloš, Jan (advisor) ; Dagmar, Dagmar (referee)
Wetland habitats are of great multifunctional importance in landscape. In particular, they have the capacity to retain water during its surplus and then in the dry season to release the water. In this work the dynamics of change in wetlands coverage was analyzed, including the representation structure of different categories of wetlands over the past 180 years in the landscape of lowlands and uplands in the Czech Republic. The historical maps of Stable Cadastre, current orthophoto and current GIS layers of localization and classification of different types of land use/cover and landscape types were used as data sources. The area of wetlands has dramatically decreased from 5 762 hectares in the period 1825-1843 (more than 9.5 % of the area) to 54 hectares in 2014 (0.9 %). Based on the study of available documents three types of wetland habitats were classified: wet meadows, wet meadows with trees and swamps . Although, the most of the historic wetlands were constituted of wet meadows (89 %) these days the swamps (48 %) form the largest part of the wetlands. Half of the historic wetlands were transformed to arable land because of increasing production of agriculture. According to the evaluation of monitored changes by predictors it was found that more pressure on the degradation of wetlands was in the areas with more suitable climatic conditions for agriculture (e.g. The Danube basin, Moravia, soil types in the lowlands, Corn agricultural production area etc.). In these areas the swamps were formed as new wetlands in places of historical watercourses localization more significantly than elsewhere in monitored area. The aim of this work was also to describe the main driving forces and pressures that have influenced the changes in wetlands. The outcome of the paper can be used in landscape planning with regard to the protection and management of wetlands.

Mophological and molecular diversity of a tropical tree species Guazuma crinita in the Peruvian Amazon
Tuisima Coral, Lady Laura ; Lojka, Bohdan (advisor) ; Helena, Helena (referee)
Fast growing tree species Guazuma crinita (Malvaceae) was selected as a priority species for domestication in the Peruvian Amazon due its important contribution to the livelihood of local farmers. Its domestication process is still in an early age as for many tropical tree species little is known about its genetic variability and we dont know anything about the impact of domestication on its genetic resources. The main objective of this research was to assess the genetic variability of G. crinita within and among populations in the Peruvian Amazon by the use of morphological (wood physical traits) and molecular (ISSR and AFLP) markers.
Wood physical properties among six G. crinita provenances were evaluated. Wood samples were drilled from the base middle and top of the stem of 12 randomly selected eight-years-old trees for determination of wood measurement. Pearson correlations between physical properties were also determined. All wood physical properties except green density differed significantly among provenances. We also found statistically significant variation due to stem level position. The moderately dense wood and the coefficient of anisotropy (1.6) suggested that G. crinita has stable wood; they represent important advantages in terms of costs for transport and transformation process. The results suggested potential to select provenances with desirable wood properties for further breeding and domestication. Due to the variation found even in limited tree samples it is recommended further analysis with more extensive number of samples from different provenances and planting zones.
This research presents the first assessment of genetic variability based on inter-simple sequence repeat (ISSR) markers for 44 G. crinita genotypes from a clonal garden multiplication established in the Peruvian Amazon Research Institute (IIAP) in Ucayali region. Ten ISSR primers amplified a total of 65 bands of which 61 were polymorphic (93.8%). The range of DNA amplification varied from 260 to 2200 bp. Among the provenances overall genetic differentiation (Gst) was 0.03 indicating 97% of genetic diversity within provenances. Gene flow (Nm) was 12.9 alleles per generation. Cluster analysis was not related with geographic origin suggesting a common gene pool which was supported by calculation of weak positive correlation was found between genetic and geographic distance.
With the use of AFLP markers an insight on how domestication process does impact G. crinita genetic resources is also reported on this research work. I was able to generate fingerprint for 58 leaf samples representing eight provenances and three population types, 19 from a natural regenerated population 15 cultivated in home garden nursery and 24 from a collection of genotypes considered as semi-domesticated population. Seven selective AFLP primer combinations were used. A total of 171 fragments were amplified with 99.42% of polymorphism at species level. Each type of population generated fragments with 72.51% 49.12% and 54.39% of polymorphic fragments respectively. Neis genetic diversity and Shannon index information were found to be higher in the population of natural regeneration compared to overall semi-domesticated population (He = 0.10 and 0.9; I = 0.19 and 0.16 respectively). The analysis of molecular variation (AMOVA) showed higher variation within provenances rather than among (84% and 4% respectively). UPGMA clusters analysis and PCoA did not showed correspondence between genetic and geographic distance in addition their correlation was not significant. There was a significant genetic differentiation among types of population suggesting slight genetic bottleneck in semi-domesticated populations yet with relatively high levels of genetic variation.
In situ conservation for populations with high levels of genetic diversity was recommended. In addition proper management of natural regeneration and ex situ genotype collections might be a good conservation strategy to maintain G. crinita genetic resources.
The use of morphological (wood physical traits) and molecular markers were successful to reveal genetic variability of G. crinita and they could be used for other tropical tree species. For further researches it is emphasis to extent the number of samples and geographic scale.
