The natural seasonal changes in the food choice and digestive tract of wild ruminants
Kamler, Jiří ; Homolka, Miloslav
Herbivore populations all over Europe have been strongly influenced by human activities. A combination of harvest, changes in forest structure, supplementary feeding, predator extirpation and others factors have led in most cases to increases of their populations and a severe impact on the composition and structure of the forest vegetation. The food choice of free living ungulate species is strongly influenced by season and animal species and changes in diet composition and quality cause the changes in the digestive tract. Effective management of ungulate populations and forest ecosystems should be based not only on detailed information about the impact of deer browsing and the number of deer to harvest but also on the density of deer species, the food supply, the structure of diets consumed by individual species, attraction and quality of the individual components of food supply the total quality of food taken and seasonal changes in digestive tract.

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.

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.

Influence of storage conditions on content of biologically active substances in apple fruits.
Ferdová, Jitka ; Čarnecká, Martina (referee) ; Márová, Ivana (advisor)
This study deals with antioxidants in diet and their effects on human organism. Further, it summarizes the agents affect the quality of apples in the course of long-term storage and it outlines the possibility of defence against them. In the experimental part methods of determination of antioxidant enzymes superoxid dismutase (SOD), catalase and polyphenol oxidace (PPO) in apples were introduced. The enzymes were measured in apples tissues in liquid nitrogen after 158 days in normal or modified atmosphere. In Apple the quantitative and qualitative analysis of proteins was realized. Further, some low molecular antioxidants (total phenolics, total flavonoids and vitamin C) as well as total antioxidant status were measured in frozen raw juice. This values were compared with values from apples analyzed immediately after the harvesting. Artificial inoculation with fungi was made in the last part and the fruitfulness was observed.

Human factor in air transport
Pískatý, Slavomír ; Šplíchal, Miroslav (referee) ; Chlebek, Jiří (advisor)
This dissertation examines the problems of human error in civil aviation. Its aim is, first and foremost, to evaluate types, origins and frequency of particular mistakes in piloting technique of aeroplanes. The dissertation comprises a study of the commonest human errors as presented by the examples of European airlines. The conclusion of the dissertation details proposals of method and approach on eliminating human error and thus increasing air travel safety.

Has Marriage and Birth Rates an Increasing Trend During the Economic Crisis?
Feurich, Marek ; Chytilová, Helena (advisor) ; Slaný, Martin (referee)
The economic crisis affects human decision-making through income and substitution effect. The aim of this work is to prove the assumption that the substitution effect operates in the Czech Republic with a higher intensity than the income effect. In other words that economic crisis has positive impact on marriage and birth rates. To test for the relationship among variables, regression analysis is performed on quarterly time series between the years 1993-2012. Two separate models for marriage and natality are assembled. Although the development of the minimum wage and the size of the gross domestic product shows positive effects on marriage and fertility rates, results demonstrate that negative effects of rising unemployment and declining interest rates operates with greater intensity. Against original assumptions is the overall impact of the economic crisis on the marriage and the birth rate proved to be negative in the observed period in Czech Republic.

Endoscopic laser-assisted cordectomies classified by Remacle and Rudert (typ I-V cordectomies) comprise a vast range of procedures from simple vocal cord stripping or submucosal cordectomy (type I) through more extensive surgery (subligamentous cordectomy- type II, transmuscular chordectomy- type III) to complete (type IV) or extended cordectomies (type V) used when tumour involves the anterior commisure, arytenoid region, subglottic region etc. Endoscopic laser-assisted surgery of the larynx is usually indicated in early stages of infiltrative malignant disease of the glottic region (Tla-b, T2) or in preneoplastic conditions (laryngeal intraepithelial neoplasia - LIN I, II or III). Radiotherapy is also believed to be an equivalent type of oncological therapy for these diseases. Both surgery and radiotherapy can worsen one of the main functions of the human larynx- the human voice. Because the overall survival rates and local control rates are quite similar in both types of therapy, one should always have in mind something that is beyond the main goal of achieving radical removal of the tumour- patients quality of life (QoL) and quality of voice. It is very interesting to compare QoL and voice quality in different types of treatment. The possibility to conserve the radiotherapy for the possible recurrence...

Motivating Alcohol Addicts to Change
Oswald, Eduard ; Dočkal, Jan (advisor) ; Klimešová, Anna (referee)
The aim of this work is to show that the theme of motivation is a central topic in case of an alcohol addict. Dependence has many dimensions as well as a man has. It hits and changes the whole personality and represents a complicated structure of factors which transcends any medical concept. The goal of this work is to confirm both theoretically and practically dependence concerns human spirituality. Furthermore, it aims to show how complicated the phenomenon of motivation is and to point out connections between the factors influencing changes of an addict and his will and effort to change as well. That is why I focus on personality as a whole at first.. Secondly, I put forth a survey of possible approaches to motivation which I regard acomplicated and complete structure, not only within a frame of psychology but regarding philosophy, sociology and spirituality as well. Like I did on the topic of dependence, I focused on links between motivation and spirituality, too, aiming to account on pastoration possibilities in this field. The goal was to show that as for working on addicts pastoration has both theoretical and practical reasons. Powered by TCPDF (www.tcpdf.org)
