Evaluation of Strain Rate Effects on Transition Behaviour Applying the Master Curve Methodology
Dlouhý, Ivo ; Kohout, J. ; Jurášek, Ladislav ; Holzmann, Miloslav
Master curve methodology has been used for an evaluation of strain rate effects on transition behaviour of wrought CrMo and cast ferritic C Mn steel.The physical aspects of strain rate effect on reference temperature has been analysed as a base for the prediction of this dependence.Statistical aspects of the strain rate effects on the master curve have been discussed showing capability of the method for the prediction of strain rate susceptibility of steel fracture behaviour. It has been experimentally proved that the master curve shape does not depend on the loading rate.The relationship between reference temperature T0 (or the shift of T0 with respect to quasi-static loading rate)and loading rate can be described with linear dependence if logarithmic scale of temporal change of stress intensity factor is considered.For experimental establishing of the dependence of reference temperature on loading rates only two T0 values as determined at different loading rates are sufficient.However,it is useful to achieve the comparable accuracy of both T0 determinations that may demand larger number of specimens for the measurement of T0 at the higher loading rate.Standard quasistatic fracture toughness has been predicted from small pre-cracked Charpy type specimens tested dynamically applying the reference temperature shift obtained experimentally.The predicted fracture toughness temperature diagram has been proved experimentally.

Is import of goods from european countries to Czech republic more or less influenced by changes in nominal and real exchange rates than in non european countries?
Vereš, Jan ; Stroukal, Dominik (advisor) ; Slaný, Martin (referee)
This bachelor thesis analyses the connection between import of goods from foreign countries to Czech Republic and the exchange rate changes. The initial hypothesis of this paper is to prove that the depreciation of domestic currency has positive influence on balance of trade balance. For this purpose there is eight econometric models which were created by using time series from years 2003 to 2016. These models are divided in pairs among four chosen countries. For each country two models were created that follow the development of trade balance between Czech Republic and one of the countries in two different time frames. All the models always use the real effective exchange rate, growth rate of GDP for Czech Republic and growth rate of GDP for one of the countries as explanatory variable. It is connected with the second task of this thesis, which is the analysis of the differences in the behaviour of the models that belong to the countries which are members of the EU and these that are not. The aim is to find out whether the existence of tariffs on imported goods from countries out of the EU causes visible differences in the behaviour of the variables that were included in the models. Based on the outcomes of all eight models the main hypothesis has been proved right for three out of four countries. In the models for Germany, China and France the relation of real exchange rate and trade balance came out as positive in long term, in short term the outcome was ambiguous. The second question of this thesis has been answered, but its added value is questionable. The final models for each state do show some noticeable differences and they can be used to determine if the influence of the change of exchange rates on trade balance is smaller or bigger in the countries where tariffs are used. On the other hand, from the results we can learn that the sample of only four countries is insufficient for the deduction of any conclusions.

Progress of the system of public health insurance and health insurance companies in the Czech Republic for the period 2000 - 2015
Pecková, Tereza ; Lukášová, Tereza (advisor) ; Bartůsková, Lucia (referee)
This bachelor´s thesis analyzes the basic funds of health insurance companies for the period 2000 - 2015 in the Czech Republic, especially the creation of resources and their use and the entire system of public health insurance in the Czech Republic. Basic funds are one of the components of the overall economy of health insurance companies. First it is necessary to describe the market of the insured. The insured create and use the finances within public health insurance. Also important are contributions from the state budget for those insured by the state. We can conclude that the cost of health insurance companies are rising and that population is aging in the Czech Republic. However, this is not a balanced linear growth. The number of pensioners grew at a slower rate of growth, but according to population development forecast, there should be faster growth in the number of pensioners in the following years. Significant growth in cost is particularly noticeable in the age category of 80 and above, and increasingly more people should live up to this blessed age, also thanks to modern public health.

Influence of social politics on fertility rate in specific regions of Czech republic
Dvořák, Josef ; Melzochová, Jitka (advisor) ; Babin, Jan (referee)
Thesis is focused on relationship between fertility rate and tools of state support. The goal is to reveal relationship between these two factors. Partial goal is to discover specific effects of tools of state support in specific regions of Czech republic. I have aimed on research at national level and also specific regions between years 1993-2014. In order to find these relationships I used method that compares differences in development of the fertility rate. After that, I set up regression model solved by method called fixed effects. For specific regions analysis was used OLS method. Model was able to explain more than 80 % of variability. This results can be used for predicting of citizens behavior, when some changes in family allowances occurs. Main finding is, that most motivating tools are parenting allowances and child benefits.

Do women with children have lower wage rate than childless women?
Lukášová, Nikola ; Brožová, Dagmar (advisor) ; Čermáková, Klára (referee)
The aim of the thesis is to demonstrate if women with children in the Czech Republic have a lower wage rate than childless women. The data from WageIndicator Foundation was processed by using the the least squares method. The conclusion is that motherhood has a negative impact on salaries. I also found that the depreciation of human capital influences only women with two or more children. It can be caused by the lenght of maternity leave. The main finding is that the wage penalty for motherhood actually exists. And the society and politicians should give the motherhood penalty more attention in the future.

Analysis of real and nominal convergence of the Visegrad Group in the years 2000-2015
Wikturna, Jan ; Strejček, Ivo (advisor) ; Zamrazilová, Eva (referee)
This Bachelor thesis is focused on a macroeconomic analysis of the process of the real and nominal convergence of the Visegrad Group countries to the old member states of the European Union, called EU-15 during the period of 2000-2015. The objective of the analysis is to confirm or disprove the hypothesis that in the selected period there is a convergence of the economically backward V4 countries with the advanced EU-15 countries and to highlight the factors that are behind the narrowing of the gap in economics and price levels. The theoretical part deals with the ways in which we measure and compare the economic performance and economic level, and explains the different approaches of the problem of economic growth and the subsequent catching up effect. The practical part is focused on a comparison of elected macroeconomic indicators and reference is made to the selected factors to determine whether, and for what reasons, the economic convergence of these selected countries made towards the developed countries of the EU-15. The analytical part confirms the ongoing process of the real and nominal convergence throughout the period, but its course is varied during different times of the period. In conclusion, it is found that the rate varied by the convergence processes and in fact positively affected the V4 countries, that joined the European Union. The incoming dynamics of the convergence, especially the prices, were significantly disrupted by the economic crisis.

The effect of investment in tertiary education on gross wages in the region Prague
Diessner, Daniel ; Chytil, Zdeněk (advisor) ; Babin, Jan (referee)
The aim of this work is to determine whether and how higher education affects gross wages. The theoretical part focuses on the theory of human capital, especially investment in education. The theory posits that a higher investment in human capital leads to higher yield, higher wages. The validity of this concept will be tested on the group of respondents who entered the labour market at the turn of millennium. Concentration of candidates with tertiary education in this period has risen considerably, which could cause an imbalance in the labour market. The practical part is based on the work of Mincer (1974). I used Mincer Earnings Function as a basis to build regression model. Partial aim is to prove the declining rate of return on investment in tertiary education using Mincer Equation.

Comparison of Selected Impacts of New Frontier and Great Society Programs in 1960s
Kojan, Christian ; Johnson, Zdenka (advisor) ; Fabianková, Klára (referee)
This thesis deals with New Frontier and Great Society programs and their impact on social policy of the United States in the 1960s. The main goal of the thesis is to compare impact of both programs on selected indicators of standard of living with primary focus on the poverty rate. Thesis describes antipoverty measures of both programs and analyzes their impact on the standard of living. Hypothesis stating that the Great Society was more successful than New Frontier at reducing the poverty rate could not be proven true because of the immense influence of strong economic growth in the 1960s. Thesis suggests that the biggest success of both programs was the positive impact of the Great Society on education.

The possibilities of influencing walking stereotypes with botulinum toxin
Kolářová, Edita ; Angerová, Yvona (advisor) ; Pochylová, Barbora (referee)
Title: The possibilities of influencing walking stereotypes with botulinum toxin Abstract: The thesis is focused on finding opportunities to influence the walking stereotype of patients suffering from spasticity of the lower limbs by botulinum toxin. The aim of thesis is to compare the quality of walking stereotype of these patients before and after the application of botulinum toxin by using a standardized test intended to evaluate the walk and based on the results to evaluate the effect of botulinum toxin on the walking stereotype. While reading the theoretical part the reader is familiar with the basic concepts related to the problems such as spasticity, botulinum toxin and walking stereotype. The scales evaluating the muscle tone are subsequently described (The Modified Ashworth scale, The Tardieu Scale) and of course the scales evaluating the walking stereotype are also mentioned (Rancho Los Amigos Gait Analysis Form, Gait Assessment Rating Scale, Rivermead Visual Gait Assessment, Tinetti Balance And Gait Evaluation). Scales evaluating the walking stereotype are also described in detail at thesis, their pros and cons are highlighted and upon the preferences of the author, one of these scales is selected to be applied in the practical part. The practical part is composed of case studies of two patients...

Development of interest rates in the mortgage market in the Czech Republic between 2006-2016
Ditrichová, Gabriela ; Strejček, Ivo (advisor) ; Klement, Josef (referee)
This bachelor's thesis is focused on the development of interest rates in the mortgage market in the Czech Republic in the decade between 2006 and 2016. A strong economic growth between 2006 and 2007, which had positive effects in the mortgage loan market, was followed by a deep slump in the form of global financial crisis unleashed by speculations in the real estate market in the U.S. The main aim of the work is based on the development of mortgage interest rates and the significant factors that affect their amount - to verify or disprove the hypothesis that interest rates respond to changes of these factors. The results confirm the hypothesis only in certain areas. The influence of changes of interest rates has been proven in the case of inflation and discount rates by usage of the econometric model. Factors that have not shown a significant direct influence of interest rates may have an indirect influence on their change.
