The current state and prospects for sustainable development of tourism in Slovakia.
Libantová, Silvia ; Indrová, Jarmila (advisor) ; Chaloupka, Radek (referee)
Tourism contributes to the prosperity of destinations by bringing financial resources, new jobs, a higher level of services and infrastructure development. However, if tourism does not develop sustainably, it is accompanied by negative factors, as well. Especially, negative impacts on the environment, such as: water and soil contamination, increased noise and overcrowded destination during the high season. As a response to the worsening state of the environment and possible irreversible changes caused by irresponsible human behavior, the idea of sustainable development is becoming more important. The theoretical part describes tourism in the Slovak Republic and highlights plans for sustainable tourism development. In the practical part, the results of the questionnaire, related to the awareness of sustainable tourism in the Slovak Republic, are evaluated. The main objective of this thesis is to evaluate the current situation in the field of sustainable tourism and to make suggestions for its future development.

Awareness of vegetarians about deficit of certain nutritions in vegetarian diet and about ways to compensate them
VORLÍČKOVÁ, Markéta
This thesis deals with vegetarians' awareness of the lack of specific nutritional substances in the vegetarian diet and their compensation. The aim is to explore whether vegetarians have sufficient information about the nutritional composition of their diet, whether they are interested in researching this information and whether the information is available and sufficient. I also looked at whether people with this eating preference are preventing potential nutritional deficits and subsequent health problems. There were designated the following three research questions: "How often and where do most vegetarians get information about a meatless diet?", "How can you achieve a full fledged vegetarian diet?" and "What is vegan awareness on the potential deficiencies in their diet, and how do they try avoid these?". In the theoretical part I deal with vegetarianism as a lifestyle, vegetarianism and its subgroups, the reasons for going to this way of life, the composition of a vegetarian diet with a focus on nutrients that may be deficient, vegetarianism and its impact on the body at different stages of development and ultimately the impact of a meatless diet on human health. The practical section is an elaborated form of qualitative research, specifically I chose semi-structured interviews. I collected the data from the interviews. The interview contained fourteen or fifteen questions, and women were also questioned about the pregnancy period. I asked questions regarding the issue of vegetarianism, veganism or raw foodism. I was interested in individual eating habits, nutrition knowledge and personal experience of the respondents. The data was collected between January 2014 and March 2014. The research group consisted of 6 respondents. The group was made up of women and men in the age range from 20 to 30 years. Among respondents there were vegetarians, vegans and raw foodists and the period of time in which they have been eating this way is different for every person. All respondents were familiar with the purpose of providing an interview and agreed to the publication. The interviews I conducted in person and were recorded on a dictaphone mobile phone. The results of my work show that most respondents do research about a meatless diet. They logically state that most intensive research took place while they were switching their eating habits, but now they still keep finding out new information. The most commonly used way was the Internet, specifically through websites such as www.soucitne.cz or www.vegan-fighter.com. Other sources used are books, articles, studies, and information received from friends or family members. The respondents argue that because the information was obtained this way, their diet is balanced. They are often trying to maintain diversity in their diet, for example, consume legumes and combine various foods such as legumes with cereals. Raw foodists state that they often consume sprouts, seeds, nuts, and of course a large amount of raw vegetables and fruits. All Vegans and Raw foodists know about the possible lack of vitamin B12, and some for this reason, use supplements. Also mentioned are supplements or protein complex supplements designed specifically for vegans.

Modelling, parameter estimation, optimisation and control of transport and reaction processes in bioreactors.
ŠTUMBAUER, Václav
With the significant potential of microalgae as a major biofuel source of the future, a considerable scientific attention is attracted towards the field of biotechnology and bioprocess engineering. Nevertheless the current photobioreactor (PBR) design methods are still too empirical. With this work I would like to promote the idea of designing a production system, such as a PBR, completely \emph{in silico}, thus allowing for the in silico optimization and optimal control determination. The thesis deals with the PBR modeling and simulation. It addresses two crucial issues in the current state-of-the-art PBR modeling. The first issue relevant to the deficiency of the currently available models - the incorrect or insufficient treatment of either the transport process modeling, the reaction modeling or the coupling between these two models. A correct treatment of both the transport and the reaction phenomena is proposed in the thesis - in the form of a unified modeling framework consisting of three interconnected parts - (i) the state system, (ii) the fluid-dynamic model and (iii) optimal control determination. The proposed model structure allows prediction of the PBR performance with respect to the modelled PBR size, geometry, operating conditions or a particular microalgae strain. The proposed unified modeling approach is applied to the case of the Couette-Taylor photobioreactor (CTBR) where it is used for the optimal control solution. The PBR represents a complex multiscale problem and especially in the case of the production scale systems, the associated computational costs are paramount. This is the second crucial issue addressed in the thesis. With respect to the computational complexity, the fluid dynamics simulation is the most costly part of the PBR simulation. To model the fluid flow with the classical CFD (Computational Fluid Dynamics) methods inside a production scale PBR leads to an enormous grid size. This usually requires a parallel implementation of the solver but in the parallelization of the classical methods lies another relevant issue - that of the amount of data the individual nodes must interchange with each other. The thesis addresses the performance relevant issues by proposing and evaluation alternative approaches to the fluid flow simulation. These approaches are more suitable to the parallel implementation than the classical methods because of their rather local character in comparison to the classical methods - namely the Lattice Boltzmann Method (LBM) for fluid flow, which is the primary focus of the thesis in this regard and alternatively also the discrete random walk based method (DRW). As the outcome of the thesis I have developed and validated a new Lagrangian general modeling approach to the transport and reaction processes in PBR - a framework based on the Lattice Boltzmann method (LBM) and the model of the Photosynthetic Factory (PSF) that models correctly the transport and reaction processes and their coupling. Further I have implemented a software prototype based on the proposed modeling approach and validated this prototype on the case of the Coutte-Taylor PBR. I have also demonstrated that the modeling approach has a significant potential from the computational costs point of view by implementing and validating the software prototype on the parallel architecture of CUDA (Compute Unified Device Architecture). The current parallel implementation is approximately 20 times faster than the unparallized one and decreases thus significantly the iteration cycle of the PBR design process.

Eating habits of patients with metabolic syndrome
NOVÁČKOVÁ, Anna
Metabolic syndrome (syndrome X, Reaven's syndrome) is frequently occurring disease in Czech Republic. The diagnosis often detected only separated parts of metabolic syndrome which are usually not connected with complex of MS. Medical conditions co-occurred within this syndrome are following: elevated fasting plasma glucose (insulinoresistance), abdominal (central) obesity (women waistline > 88 cm, men waistline > 102 cm), elevated blood pressure, high serum triglycerides (> 1,7 mmol/l), and low high-density cholesterol (HDL) levels (women 1,25 mmol/l, men 1,0 mmol/l). The incidence of MS can be divided into the prevalence of MS itself (this correspond with 30%) and the prevalence of each individual part of MS which correspond with 80% population. The most frequently reasons of MS are so called environmental impacts as e.g. central obesity, insulinoresustance syndrome, fatty liver, systemic inflammation, intestinal alterations, hypertension, hypertriglyceridemia, foetal malnutrition, low basal energetic outcome, sleep apnoea syndrome, changes of gut flora, hyperglycaemia and cumulation of visceral fat. This bachelor´s work is concerned with eating habits, life style and other factors which could be reason of described metabolic syndrome. The aim of this study is evaluation of eating habits and life style of patients suffered from MS before syndrome outbreak, as well as participation of obesity in MS outbreak assessment. Two explorative questions were formulated on the basis of described goals: First research question: Did the MS patients follow principles of healthy eating before syndrome outbreak? Second research question: Does obesity have a significant effect on MS outbreak? Definition and characterization of MS in relation to diet is described in theoretical part of my work as well as explanation for reasons of MS outbreak, descriptions of each separated diseases of MS complex and their treatment. Metabolic syndrome in connection with obesity and its classification into each level is defined inthis part. Obesity treatment together with prevention and treatment of MS are suggested in terminal part of this section. In practical part of work, the results of own research are presented. This section is focused on: 5. evaluation of eating habits before MS outbreak; 6. obesity incidence in MS patients; 7. patient´s life style; 8. the presence of individual diseases participate in MS. Research part of my bachelor´s work is prepared with using of quantitative assessment, which was done by questionnaire investigation in southbohemian and westbohemian region. Research population consists of thirty gender-nonspecific and age various patients diagnosed as having MS. The research questions were focused on mapping of respondent´s eating habits, life style (smoking, movement activity, daily eating portions and breakfast regularity), previous and current illnesses as well as diseases of respondent´s relations. The aim of described investigation was evaluation of obesity, life style and diet participations in MS outbreak. The results did not prove observance of healthy eating principles in MS patients before and after syndrome outbreak, while most of respondents were overweight or obesity. It can be assumed that genetic predispositions play role in MS outbreak. Additionally, very interesting is detected occurrence of MS in many individuals younger then forty years old. The present work extended the knowledge about risk factors of MS outbreak together with eating habits, obesity and MS outbreak connections. When reasons of MS seem to be more clear, it is easier to establish new more effective prevention. On the basis of the results, it can be arranged diet suggestions useable as effective prevention of MS outbreak.

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.

Sperm protein profiles of different mammalian species
Pohlová, Alžběta ; Zigo, Michal ; Jonáková, Věra ; Postlerová, Pavla
Proteins are a substantial equipment of the spermatic cell; therefore, the characterization of sperm proteins is crucial for explanation of molecular mechanisms in the reproduction process. We isolated sperm proteins from different mammalian species - pig, bull, human, mouse, dog and cat. Extracted proteins were separated by SDS-electrophoresis and protein/glycoprotein profiles from epididymal or ejaculated sperm were compared. Additionally, we tested cross-reactivity of antibodies prepared to sperm boar proteins on spermatozoa of other mammalian species using immunofluorescent technique. Our future plan is to compare the protein profiles of sperm during their functional development (epididymal, ejaculated, capacitated) in various mammalian species and identify species-specific sperm proteins with zona pellucida binding activity.

Interpretive principles in Verdi's operas
Beneš, Andrej ; HAJÓSSYOVÁ, Magdaléna (advisor) ; VOTAVOVÁ, Yvona (referee)
The master’s thesis deals with the theme creation of the opera production of Giuseppe Verdi with the focus on his opera Falstaff and deals with significant important interpretations of this opera. This dissertation is supposed to bring a complete picture of Verdi’s opera production pointing out some details which are not commonly known nor from the public nor in the professional music world. What appears in this work is Verdi’s correspondence (letters). I consider these letters an authentic source to understand Verdi’s creative and artistic intentions. Hereafter I portray an idea of how to perceive opera Falstaff not only from my point of view but I used the lead from the Italian reviews and musicology.

Age management
Jirásková, Barbora ; Dvořák, Marek (advisor)
This thesis processes the concept of the human resources management with respect to the age structure of employees in the intentions of the Czech Republic. In the theoretical part, there is outlined the history of the application of the principle of age management, focusing on current demographic trends, forecasts of population age structure, the aging workforce and the need to preserve the ability to work into old age. Points to the need to adapt corporate strategy, personnel management trend of an aging population. It presents ideas for the main underlying programs and legislative measures which form the basis of the latest concepts and strategic plans in the Czech Republic and Europe. The empirical part deals with a specific level of allowance organization established by TSU and two sub investigation. The first is a case study of age management staff. The resulting data are confronted with the results of a survey among employees of the organization. The second investigation are interviews with members of management and employees of the HR department on the issue of the introduction of age management, their awareness of the concept of age management, the question of age discrimination, the issue of maintaining the continuity of knowledge in the organization and their views on these topics. The outcome of this survey indicates a willingness and readiness of the organization has already received age management principles adhere to and develop further.

Determination of content substances for selected species and varieties of roses.
Slavíková, Eva ; Sus, Josef (advisor) ; Súkeníková, Tereza (referee)
This bachelor's work is focused on comparing the most significant content substance, vitamin C, in fruits of chosen rose kinds species and varieties. Herbal products are often seen by people as products of "second choice", when failure of allopathic treatment occurs, which is focused especially on suppressing symptoms of illness, but it ignores health of the human body as whole. That's why are herbal products often alternative for therapy of chronic diseases. The base of this work is extensive literary research and results of laboratory measurings. Literary part of this work includes description of botanical classification of rose plants. There is stated basic characteristic of individual rose species and their morphological features. In following chapters is composed overview of effective substances in rose fruits and their effect on human health. In practical part of this work are included results of laboratory tests for determining ascorbic acid content for chosen samples of rose species and it also includes results of weighing and measuring of fruit samples of chosen rose species. There are also stated chosen rose species and shortly their origin and description, in the beginning of practical part. For practical part were chosen samples of species. Results of practical part are compiled into statistic tables and graphs and it confirms high content of ascorbic acid in rose fruits. This content is in range of cca 300 - 900 mg.100 g-1. Due to growing interest in alternative treatment options and "clean" natural product, it can be assumed, that many plants of Rosaceae family will keep its place in treatment practice. Those plants will be used not only for treatment of acute and chronic diseases, but also for cosmetic products production, thanks to its large effects and process options.
