Statistical investigation of CT pulmonary angiography in terms of development and depending on age and sex in District Kroměříž 2006-2010
OPLUŠTIL, Vladimír
CT pulmonary angiography is, together with ventilation-perfusion scintigraphy, the main diagnostic methods for recognition as pulmonary embolism. This is a very dangerous disease, which may end up even in death. Its share of deaths in hospitals, including subsequent ? complications, is around 4%. Therefore, emphasis is placed on early diagnosis. Clinical and laboratory symptoms are unspecific (including D Dimer).(10) Pulmonary embolism after ischaemic heart disease and arterial hypertension the frequency of its occurrence, the third most serious cardiovascular diseases. Cause of death in pulmonary embolism is usually the exhaustion of the right heart, seeking to overcome suddenly increased the resistance of the pulmonary circulation. This is the pulmonary artery or its branches is embolism blood clot-trombus, resulting in the venous system or in the heart, a saddle embolus, patched up a significant part of the lung. The most common place of trombs, which embolizated to the lungs, are deep veins of lower limbs if they are affected by the flebotrombolitis.(16) In addition to the acute embolism are frequent and chronic embolism. They are equally dangerous. By gradually and subtly clog small blood vessels, reduces the total cross-sectional area of open pulmonary artery, which have blood flow, and since the volume of blood must be maintained even in the smaller section of the vascular bed, should permanently increase the blood pressure in a small circulation, which is also dangerous.(16) In my work is the methods of mathematical statistics processed file 1966 CT pulmonary angiogramy (CTPA), carried out on the CT work in Kroměříž in the years 2006-2010. The work is focused on the statistical survey of the influence of age, sex, and the time evolution of the CTPA during that period.

Evropský trh s elektřinou a energetické politiky států EU
Veselý, Aleš ; Klosová, Anna (advisor) ; Resende, Moises (referee)
The main focus of this thesis is to find out what factors have the biggest influence on the price of electricity for household consumers in the European Union in the context of creating the internal electricity market in the EU. By means of the cluster analysis six EU Member States have been selected according to the following criteria: electricity consumption, electricity production, and the price of electricity. As a result of that Belgium, the Czech Republic, Estonia, Hungary, Malta and Sweden have been selected. Consequently, the regression analysis has been carried out to find out what factors influence the electricity prices in every country individually. The independent variables are mainly various sources of electricity production. It was found out those renewable resources most influent the electricity price for households in Belgium, Estonia, Hungary, and Sweden. Nevertheless, in the context of Europe 2020 strategy and the formation of the European energy market, one of the European Commission's objectives is to increase the share of renewable sources in the production of electricity in the EU Member States. Therefore, it will bring about higher prices of electricity, which goes against the Commission's effort to decrease the price of electricity for households through the liberalisation of electricity and the creation of the internal electricity market.

Analysis of the demand for services of selected driving school
Milatová, Barbora ; Mičúch, Marek (advisor) ; Koubek, Ivo (referee)
This thesis examines effects of selected factors on the demand for services in chosen driving school. Testing, carried out by the regression analysis, demonstrates how the total monthly sales are influenced by prices of different types of courses, selected marketing strategy, the presence of discount in a given month, the success of students in driving exam, the number of training cars and the number of training teachers. Furthermore, the price elasticity of demand for two types of courses has been measured. These courses had been selected due to their most significant impacts on the price elasticity of demand. Once the model had been transformed and the four variables causing multicollinearity have been omitted, the final result showed that the demand for driving is mainly influenced by well-chosen marketing strategy and a success of students at their first examination. The effect of price of the course on the demand proved to be insignificant.

Who Are the Users of the Discount Coupons?
Vejtrubová, Zuzana ; Svoboda, Miroslav (advisor) ; Babin, Jan (referee)
The main objective of this bachelor's thesis is to find out, who are users of discount coupons. Hypothesis are tested on the panel data including 107 observations. This data are obtain from customers of drugsotre DM, which provides discount coupons for their customers. Object of one of the hypothesis was that users of coupons are more price elastic than nonusers. This hypothesis was confirmed for two of three selected products. Other hypothesis are related to what are the households, which use discount coupons. The results of analysis show, that users of coupons are households, where female head is unemployed, have higher education, is older and do not have children. All these results confirm the hypothesis. Only hypothesis that income has positive effect on coupon usage intensity remained unconfirmed.

The analysis of a relationship between the level of public ownnership and the procurement effectiveness in utilities sector
Rističová, Sara ; Pavel, Jan (advisor) ; Zídková, Hana (referee)
This master thesis is focused on the public procurement in the utilities sector. The main objective is to analyze the influence of the level of the public sector ownership on the public procurement effectiveness. To give the complex view of the problem, the study also determines the final impact of the public procurement effectiveness on the global operational effectiveness. The theoretical part starts with the analysis of the legal directives and the environment in the relevant sectors. The analytical part uses the econometrics methods for the data file of utilities sector procurement from the period of 2006-2011 based on the information from ISVZ and Creditinfo-Albertina systems. When the conclusions are made, the public sector ownership has the positive impact on the public procurement effectiveness but the contrary effect on the global operational effectiveness.

Regression and correlation analysis of time development of the traffic accidents number at transportation of dangerous substances in a selected region.
VÁVRA, Martin
The aim of this thesis was to conduct a statistical survey and the measurement of statistical dependences of time development of the traffic accident rate at transportation of dangerous solid, liquid and gaseous substances, including their total number and also in case of leakage of these substances in a selected region "the Czech Republic". The purpose of the thesis was to verify statistical data, or more precisely, verification of two basic hypotheses H1 and H2, and five sub-hypotheses H11, H12, H13, H14, H15. For these verifications methods of descriptive and mathematical statistics were used, especially regression and correlation analysis in hypothesis H1. To verify hypothesis H2, nonparametric normality test as a technique of mathematical statistics was applied. Verification of hypotheses H1 and their sub-hypotheses H11, H12, H13, H14, H15 enabled to prove linear regression associated with negative correlation within the development of traffic accidents at transportation of dangerous substances in annual units of time (2002 to 2011). Verification of hypothesis H2 enabled to demonstrate normality in distribution of the number of accidents at transportation of dangerous substances within individual months of the monitored period from 2007 to 2011. As benefits of this thesis both the proposal of the sequence of statistical methods for examining the research topic and the application of the mentioned statistical methods to the number of traffic accidents at transportation of dangerous substances can be considered Based on the results of this study, possible follow-up research work may be suggested. A research is proposed which would survey the ways of prevention or other factors leading to negative correlation dependence. Another possibility of follow-up research work could be, for example, statistical surveys and the measurement of statistical dependences in regions of the CR or investigation of the theoretical distribution of the number of traffic accidents at transportation of dangerous substances within a different time unit.

Size of tax rates in relation to the tax revenue
Frey, Marek ; Vokoun, Marek (advisor) ; Vebrová, Ludmila (referee)
This thesis examines the question of adjusting the size of tax rates in relation to the tax revenue on a sample of EU countries and on the example of the Czech Republic. Research is hold thanks to the Eurostat statistics related to the reporting on the implicit tax rates of capital, labour and consumption allowing us for an international comparison for the period from 1995 to 2008. Thanks to the Components of total tax revenue growth analysis and Regression analysis of tax revenue we shed some light on investigation of current understanding and interpretation of the issues of taxation, tax competition within the EU and the avoidance of excise taxes, taxes on labour and capital. Our results suggest that there are Laffer curves with decreasing returns to scale in case of excise taxes, taxes on capital. In case of labour taxes there seems to be complicated relationship, however, in one of the models traditional-like curve were introduced. If we change the tax rates on capital we can most probably expect decreased tax return between two years but further investigation to this issue is needed.
