Differences between men and women in the Czech labour market
Stroukal, Dominik ; Kadeřábková, Božena (advisor) ; Pavelka, Tomáš (referee) ; Němec, Otakar (referee)
This thesis consists of five articles that apply current world research on labor economics at the Czech Republic and confirms the significant differences between men and women in this market. It shows that gender has a significant influence on the preference on the labor market and, consequently, on employment and health. First, the thesis shows that preferences are relevant determinant of career and then we study the difference in preference of salary for men and women. Subsequently it shows that gender plays a significant role in explaining the relationship between homeownership, and unemployment, as well as unemployment and health. The first chapter was able to demonstrate that the preference for a career has a positive influence on the choice of career. The influence of higher education on prioritizing career proved to be positive and significant. Probability of a career choice is reduced by the presence of children, however, is not dependent on their number, which is contrary to the theory of preferences. The second chapter shows that Czech women prefer more non-monetary rewards than men. It has also been shown that people with university education are same in the preferences of non-monetary rewards regardless of the gender of the respondents, however, compared to the world's research, the Czech higher education increases this preference. It turned out that women prefer risk less than men. The third chapter demonstrates that although the housing market undermines labor mobility and employment in the Czech Republic at the regional level, therefore, that in regions with a higher rate of home ownership is higher unemployment, at the individual level, the owners of housing are unemployed are less likely. The estimates are significantly different for men and women. Men living in owner-occupied housing have a higher likelihood of employment than women. At regional level, however, this thesis shows that the high rate of home ownership increases unemployment for both men and women, in the long run only to women. The fourth chapter showed that men transition to homeownership reduces the likelihood of unemployment next year. For women, this relationship has proved to be insignificant. In addition, as insignificant showed the opposite relationship, the transition from unemployment to the newly acquired home ownership. The last chapter shows that the change in the working status to unemployment will increase in the future probability of worse health. Influence in less than two years, however, proved to be significant. An important conclusion is that men have a significantly stronger relationship between health and unemployment than women.

Internal equity principle in the context of company strategy
Kopecký, Martin ; Nový, Ivan (advisor) ; Háša, Stanislav (referee) ; Blažek, Ladislav (referee)
The thesis deals with the scientific problem of the link between the strategic management and the compensation system using the principle of internal equity. The work is based on two pillars, namely the qualitative research and own proposed solution. The first part of the thesis describes the qualitative research and the possibilities and the synergistic effects of linking business strategy and compensation system. The qualitative research is performed as a multi-case study and investigates the phenomenon in the practice of three companies from various markets (the Czech Republic, Slovakia and Bosnia and Hercegovina) and industries (finance, IT/Telco and FMCG). The research tries to find answers to the four research questions: How does business strategy influence compensation process? How can compensation support the realization of a business strategy? How can business strategy be linked with a compensation system within the principle of internal equity? How can compensation reinforce the strategic function of the human resources management? The research is based on the study of theoretical sources as well as on practical fieldwork. The qualitative research itself uses qualitative research methods for data collection, such as observations, questionnaires, and document analysis. The population questioned was top managers, line managers and representatives of HR department. In total, 142 interviews were performed by a single person. The collected data were analyzed and the triangulation was applied. The findings were summarized and generalized into a final report that brings answers to the research questions above. The research brings valuable findings used in the second, design part of the thesis. The own proposed solution consists of two main models. The first one is a simplified scheme of the compensation system and the second one is a model of strategic segmentation of jobs. The first model could be used successfully in the business practice as well as in education. The second model of the strategic job segmentation brings answer to the question of synergistic linking of business strategy and the compensation system within the principle of internal equity. The model brings valuable findings and a foundation for further theoretical research and its further development. The model also brings practical solution to the design of related policies and processes in the strategic management of human resources. By the design of both proposed models the main objectives of the thesis were achieved.

Dietary supplements and iodine supplementation for children 11-12 years in the Czech Republic
HALÁSZOVÁ, Monika
Bachelor Thesis called "Dietary supplements and iodine supplementation for children 11-12 years in the Czech Republic" deal with the intake of dietary supplements containing iodine and intake of other significant dietary sources of iodine in relationship to saturation with iodine in the monitored group of 300 children aged 11-12 years . The thesis is divided into theoretical and practical part. Theoretical part deal with established issues in light of current situation and uses the knowledge of specialized literature in these areas: iodine and his dietary sources, influence of deficient or excessive intake of iodine on thyroid gland and its function, and also the solution to iodine deficit in Czech Republic. The thesis also deals with dietary supplements and nutrition of school-aged children. Practical part is focused on quantitative research. This research was done on selected group of children who had low level of ioduria (iodine in urine) according to State health institution. Statistical file included 300 children of both gender in age from 11 to 12 who live in Czech Republic. The reason why children of this age were chosen is because of importance of optimal intake of iodine in period of physical and sexual evolution. The children were divided into two groups. One group had ioduria up to 300ug/l and the second group had ioduria over 300u/l. Data were collected through questionnaire. Because of age of respondents, the questionnaire was filled in presence of at least parent. The questionnaire should have also served to parents as information about iodine importance for their children. The individual evaluation of ioduria and questionnaire was given to parents upon their request. Collected data were evaluated in Microsoft Excel. In practical part, two main goals and two research questions are set. Their task is to determine the rate of usage of dietary supplements with iodine and to find out what significant sources of iodine the children with ioduria over 300u/l take in. The milk and milk products, salt with iodine, salted delicacies, sea products and dietary supplements with iodine were observed as probable main sources of iodine intake. The first goal was to find out the amount of iodine intake from dietary supplements for previously mentioned group of children. The second goal was to find out if the dietary supplements with iodine (or any other combination of food rich on iodine) are used by observed individuals with ioduria over 300u/l. The results of research show if the respondent's level of ioduria is affected by in taking the dietary supplements or food with significantly higher content of iodine. My own research proved relatively frequent (but irregular) intake of dietary supplements with iodine by whole examined population. On the other hand, usage of dietary supplements with iodine is probably not correlated with usage of table salt without iodine or with thyroid gland illness by individual respondent or in his family. The milk and milk products and table salt with iodine proved to be the main source of iodine. According to research, children with excessive ioduria consume sources of iodine as frequent as other children. Deeper insight into results shows that reason for excessive saturation with iodine is combination of intake of dietary supplements as well as other significant food sources of iodine, especially milk and its products. By several respondents, the higher level of ioduria can be caused by higher consummation of sea products or by usage of dietary supplements with iodine in last two days. The need for better awareness about suitable rate of iodine dietary supplements intake as well as medical importance for lowering the amount of (iodine) table salt in food was discovered by research. The optimal supply of iodine by higher percent of observed population could be also achieved by optimizing the content of iodine in milk.

Grammars with Restricted Derivation Trees
Koutný, Jiří ; Janoušek, Jan (referee) ; Vojnar, Tomáš (referee) ; Meduna, Alexandr (advisor)
V této disertační práci jsou studovány teoretické vlastnosti gramatik s omezenými derivačními stromy. Po uvedení současného stavu poznání v této oblasti je výzkum zaměřen na tři základní typy omezení derivačních stromů. Nejprve je představeno zcela nové téma, které je založeno na omezení řezů a je zkoumána vyjadřovací síla takto omezené gramatiky. Poté je zkoumáno několik nových vlastností omezení kladeného na cestu derivačních stromů. Zejména je studován vliv vymazávacích pravidel na vyjadřovací sílu gramatik s omezenou cestou a pro tyto gramatiky jsou zavedeny dvě normální formy. Následně je popsána nová souvislost mezi gramatikami s omezenou cestou a některými pseudouzly. Dále je prezentován protiargument k vyjadřovací síle tohoto modelu, která byla dosud považována za dobře známou vlastnost. Nakonec je zavedeno zobecnění modelu s omezenou cestou na ne jednu, ale několik cest. Tento model je následně studován zejména z hlediska vlastností vkládání, uzávěrových vlastností a vlastností syntaktické analýzy.

The Pump with a Diffuser with Stochastic Blades (Runner and Diffuser)
Dobšáková, Lenka ; Melichar, Jan (referee) ; Veselý, Jindřich (referee) ; Haluza, Miloslav (advisor)
This doctoral thesis studies the non-uniform blade cascade for centrifugal pumps. Influence of non-uniform blade cascade is investigated on the impeller and diffuser. A non-uniform blading impeller of pumps in this doctoral thesis was examined in terms of influence on efficiency characteristic. The idea of using non-uniform blading is to obtain a flat efficiency characteristic. Then the centrifugal pump could be used on larger scale of power with achieving a sufficiently high efficiency. The work is based on experimental measurements and numerical simulations of non-uniform hydraulic pump components. Non-uniform impeller and the diffuser were newly designed for this research. A new measuring track of small submersible pumps was needed to design and build for measurements. Different pump combinations with conventional hydraulics on one working point and hydraulics with non-uniform were measured. All measurements were evaluated and characteristics of efficiency, head and power were obtained for each measured combination. Some of pump combinations (which were measured in experiment) were numerically simulated by program Ansys Fluent. Data needed to evaluate the characteristic of efficiency and specific energy were collected from each numerical simulation. A theoretical consideration concerns the influence of non-uniform blade cascade applied on diffuser. The suggestion how to decrease hydraulic losses in canals was done. The theoretical consideration how to make a flat efficiency characteristic was made.

Specifics of nursing care in patients after transapical aortic valve implantation.
VOTRUBOVÁ, Nataliya
Transcatheter aortic valve implantation (TAVI) is a new and an attractive method in cardiology and as well as in cardiac surgery. It is constantly evolving method which has been developed as an alternative to standard open surgery, especially in patients with severe symptomatic aortic stenosis with unacceptably high perioperative risk or patients who are not suitable for conventional open heart surgery because of age and comorbidities.A teamwork is very importantfor this new method and approach. The choice for TAVI is discussed by the institutional multidisciplinary heart team, typically consisting of interventional cardiologists, imaging-specialists, cardiac surgeons and anaesthesiologists. The first implant in a human being was performed by Cribierin 2002. In Czech Republic this method was first used in 2008. Transcatheter aortic valve implantation (TAVI) was accepted as a minimally invasive alternative to open surgery. This method does not require the use of cardiopulmonary bypass, and cardiac arrest. Other several benefits includinglower risks of bleeding and stroke events, better wound healing, less pain, as well as more rapid early recovery due to preservation of continuity of the sternumthat result in shorter durations of stay in the hospital, earlier rehabilitation and faster returns to normal life. In the presented work was used a combination of qualitative-quantitative methods of investigation. The data was obtained by using the quantitative research. The main technique was using the questionnaires designed for nurses working at the Department of Cardiac Surgery, Hospital Czech Budejovice, a. s. These results were backed up by the implementation of qualitative research, which investigated the patients and physicians view on monitored issues. Questioning method using a semi structured interview technique was used for qualitative research. The results of the survey were processed using descriptive statistics charts in LibreOffice Calc and using diagrams created in LibreOffice Writer. Qualitative results of the research were transcribed from audio recordings and coded, and the base code was created nine categories of interviews with clients/patients and three categories of interviews with doctors. The aim of this work was to explore the specific problem of nursing care about the clients / patients after transapical aortic valve implantation. On the base of our obtained data it is evident, that the client/patient after TAVI may be positioned sideways, the use of surgical drains are less frequently, so the care about the surgical wounds is simpler, patients report less pain in the surgical wound and postoperative rehabilitation and recovery is shorter. H1 - The nurses take care about the clients/patients after transapical aortic valve implantation in the same way as about the clients/patients after open aortic valve replacement, without realizing the differences between the patients treated with different approaches, was not confirmed. The nurses'sees/reported major differences in invasiveness and extent of providing care, rehabilitation, convalescent, in the duration of the hospitalization and better cosmetic effect. The results of the research can serve as a basis for creating the standards of nursing care or educational material for clients/patients. It is also possible to present the results of this work at a specialized seminar for non medical healthcare workers and results can also increase the quality of nursing care about the clients/patients after transapical aortic valve implantation.
