Resistance of HDPE materials against crack propagation from two-parametric fracture mechanics point of view
Bareš, Pavel ; Fiedler, L.
The influence of geometry constraint on the resulting values of fracture characteristics of HDPE material is analysed. To this aim the crack growth resistance (J-R) curves and the initial fracture toughness values for HDPE material were experimentally determined for an arc-shaped test specimen with and without protective layer. Two parameter fracture mechanics is applied and transferability of the experimental data to the two-layer pipe used in praxis is discussed. Finite element calculations were used for the investigation. It is concluded that the estimation of the service life of pipes based on the approach is conservative.

Risk group of persons with disabilities on the labour market in Prague from 2005 to 2015
Hošková, Laura ; Maule, Petr (advisor) ; Lukášová, Tereza (referee)
The theoretical part of the Bachelor Thesis comprehensively illustrates the status and representation of persons with disabilities (PWD) on the current labour market in the Czech Republic. In a general manner, the Thesis looks at the employment policy as well; especially its legislative basis in the legal framework of the Czech Republic and selected EU countries. Furthermore, the legal obligations of employers of PWD and the possibilities of fulfilling the mandatory share of PWD employment are stated. Findings of two qualitative employment studies are presented showing that PWD enter the labour market equipped with specialized competencies, which they are willing to complete by retraining programmes in case of need. The employers perceive the employment of PWD mainly as a financial profit, granted to them by the state; and the legislative conditions are a sufficient incentive for them. The questionnaire survey pointed out that the weakness in the employment of PWD is the lack of part-time jobs, which are highly demanded among them. Therefore the Thesis presents a solution, which could be the creation of shared work positions.

Nizamov, Kirill ; Pecinovský, Rudolf (advisor) ; Šlajchrt, Zbyněk (referee)
The thesis is concerned with a comparison between a Java framework called Spring and Grails, Zend, Nette, NodeJS, Play, Symfony, OpenXava frameworks described in the theses of Odehnal [1], Kočárek [2], Kadlec [3], Dočkal [4], Šimon [5]. The thesis consists of two parts. The theoretical part introduces the Spring ecosystem and its individual modules to the reader. This part also outlines trends and estimates Spring position and popularity among other Java frameworks. The practical part focuses on web application development based on the criteria defined in the Odehnal's thesis [1]. The sample application shows the style of development in the Spring framework and its functionality and capabilities. Based on the gained experience during the sample application development, Spring is next compared to the other frameworks mentioned earlier and included into the previous comparison. The comparison criteria are specified in the Odehnal's thesis [1] and consist of 4 areas. First of all, there is a basic framework differences comparison. Next, there is an architecture comparison. The third area involves a comparison of work with the framework which also contains both objective criteria and personal estimation. The last part is dedicated to a comparison related to framework support, available literature and overall popularity. The result of this thesis is a comparison of 8 frameworks including the created sample application, which should help the readers when selecting one of the them and should make it easier to orientate in the world of web frameworks.

The Controlling Study
Herda, Tomáš ; Mikovcová, Hana (advisor) ; Herda, Zdeněk (referee)
The main goal of this Diploma´s Thesis is to make a model for calculation of water and sewer rates for the company Vodovody a kanalizace Náchod, a.s. when sticking to the set criteria both from the side of VaK Náchod, a.s. and law regulations. Based on the theoretical part an analysis of customer sensitivity to the price changes using the data for last 20 years follows. Findings from the first two parts are used in risk analysis in next part. The created model calculates the water and sewer rates based on the information from the company accounting system in the way to generate sufficient financial resources to fulfill the renovation plan of infrastructural property plant and equipment and to transfer given amount to the company funds. In addition, the model monitors whether the legal condition of maximal allowable increase of profit per m3 is met. In the customer sensitivity to the price changes part the price elasticity of demand for water and sewer rates is calculated based on the data from 1995 to 2015. The assumption of inelastic demand is confirmed. Risk analysis part is deals with potential risk regarding the demand and prices. Potential impacts for the most significant risk are quantified. The analysis uses knowledge gained in the first two parts. It was confirmed that potential risks are exiting but do not have any significant impact on the going concern of VaK Náchod, a.s. The created model has been already used for the calculation of prices for the year 2017. Customer sensitivity analysis to the price changes and link to the potential risks is an additional information for VaK Náchod, a.s. which validates that nowadays, there are no significant threats which could affect the demand and water and sewer rates significantly.

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.

Comparison of methods of ECLIA and ELISA in determining the beta-CrossLaps
KOŽANTOVÁ, Jana
Osteoporosis is a very old disease affecting a large majority of population. Its occurrence rate has been growing permanently. It is a systemic disease of bones for which the decrease in bone mass, i.e. of inorganic as well as organic bone part is characteristic. Typical symptoms are osteoporotic fractures. To perform an in time diagnostics of the disease, it is necessary to execute the necessary examinations. One of them is also the laboratory determination of markers of bone resorption and new creation for finding out the state of bone metabolism. The target of my bachelor thesis was to find out the level of the bone resorption marker (beta-CrossLaps) by means of ELISA and ECLIA methods on the same serum from patients with the diagnosed osteoporosis and to process statistically the results. In the next part I dealt with the structure and functions of bones. Then I focused on markers of bone formation and resorption. Finally I mentioned the bone metabolism and its control mechanisms. I concentrated mainly on the metabolism of calcium, D vitamin, parathormone and calcitonin. I carried out the practical part of my bachelor's thesis in the accredited private laboratory STAFILA, spol. s r. o. in České Budějovice. The procedure of my work followed the standard operating procedure of the laboratory. In the research, in total 66 serums of patients with osteoporosis were analysed by me. At first, I determined the concentration by beta-CrossLaps method based on the principle of sandwich ELISA on the appliance NexGen Four from TestLine company. Then I analysed the same samples on the automatic analyser IDS-iSYS from IDS company, this time by ECLIA method. Both appliances on which the determination was executed, principles of both methods, applied analytic sets and the procedures of analysis are described in the methodical part. In the next part of my bachelor's thesis, the results of my measuring are stated. At first I entered the concentrations beta-CrossLaps in ng/ml measured by both methods into the table and for the respective samples I stated the sex and years of birth of individual patients. Moreover I prepared a graph illustrating the share of men and women of various age categories in my research. The second graph shows the differences in values of beta-CrossLaps concentrations between both methods. Resulting concentrations were subject to regression analysis. I applied linear regression and Grubbs test for finding out the outlying values excluded from the further statistical processing. I performed Passing-Bablok regression based on the remaining values. As a result of regression equation and 95% CI of the slope B and intercept A, the proportional error of measuring was rejected but on the contrary, the systematic error was confirmed. Correlation coefficient R = 0,97 shows a very good linear dependency between both methods. It turned out by practice in the laboratory that the evaluation of concentrations beta-CrossLaps from the same patients on various appliances may show partially different values. I worked at two different analysers, each of them was based on another principle, with a different sensitivity and calibration. All of this could have the influence on the resulting concentration of individual samples. The advantage of automatic analyser IDS-iSYS is a quicker determination. Moreover it is possible to perform on this apparatus all the possible examination concerning the bone metabolism from D vitamin, parathormone, osteocalcin up to bone markers. It is advantage for the patients with osteoporosis as well as with other metabolic skeleton diseases. It follows from this that all the necessary examinations may be carried out on one apparatus.

Expert capacities of the Czech political parties: case study of defence policy
Bayerová, Anežka ; Němec, Jan (advisor) ; Vymětal, Petr (referee)
The thesis deals with marginally explored area of expert capacities of the Czech political parties with respect to the different organizational types of selected political parties and movements. The work aims to find out what expert capacities work for these types of political parties, how these experts are recruited in their position, whether it corresponds to their educational background and professional experiences with function, which are they holding in the expert authority. Work is elaborated in the form of case study, which focuses on the activities of defense policy expert commissions. The text is divided into two theoretical and one empirical chapters. The first chapter deals with the process of policy-making, its actors and activities associated with this process. The second chapter defines the various types of political parties first from the mainstream perspective (cadre, mass, catch-all parties), which complements the modern concept of business party and finally there is a typology of S. Wolinetz (office-seeking, vote-seeking, policy-seeking parties). The last empirical chapter presents the case study focused on four Czech political parties (TOP 09, KSČM, ČSSD and political movement ANO 2011) and their access to party expertise. The result of this work is to compare the level of analytical capacity across selected political parties/movements and testing of hypotheses formulated in the introduction of the thesis.

International trade with fresh fruit and vegetables
Laketić, Aleksandar ; Štěrbová, Ludmila (advisor) ; Halík, Jaroslav (referee)
The main goal of my Master´s thesis is to evaluate dynamic environment of international trade with fresh fruit and vegetables. In the first part of my thesis I analyzed importance of the production of fresh fruit and vegetables for economies of selected countries. Next I had described the trade flows and patterns. In the second part I made a characterization of payment terms and trade negotiations in the context of international trade with fresh fruit and vegetables. Furthermore I made an analysis of import and export rules and regulations of the EU. Based on this analysis I came to general conclusions on the trade policies of countries and communities. In the last part of my thesis I applied findings from the previous parts on the analysis of two cases. The first analyzed case is the situation of imports of Chinese pomelo to the EU, with regards to maximal residue levels of pesticides. Second analyzed case is the situation of South African citruses imported to the EU, with regards to the problematic of citrus black spots.
