Transition from Accident Prevention and Flight Safety Programme to Safety Management System in a small air operator
Hloucal, Aleš ; Kujal, Tomáš (referee) ; Schaumann,, Ondřej (advisor)
The aim of the Master´s thesis is the design process of transition to a fully integrated safety management system, taking into consideration the unique characteristics of small air operators. It means describing the initial situation, studying the requirements and recommendations of ICAO Doc.9859 a proposal for the transition to fully integrated security management system, taking into account the specifics of a small air operators. Work also includes a description of the "target state", all inputs, outputs and main functions, integration into the quality system and the organization of society as a whole.

Car cabin passive cooling system performance study
Viščor, Petr ; Hejčík, Jiří (referee) ; Fišer, Jan (advisor)
The work is focused on issue of passive cooling in a cabin of a car. The basic principles and mechanisms of heat transfer are described in the theoretical part and the quality of cabin environment in terms of thermal comfort and air quality is discussed as well. Next part of the work describing the principles of ventilation and air conditioning of cabins and possible methods of passive cooling are discussed. Passive cooling means decrease of temperature of cars interior, without need of energy supply from car battery, or fuel. The last part of the work includes numerical simulation of selected methods of passive cooling using the THESEUS-FE 3.0 software. Simulations were performed on model of Volkswagen Polo car and primarily were focused on testing of functionality of various methods of passive cooling.

The use of bioimpedance analysis for kidney function evaluation
Veselková, Alena ; Šrámek, Petr (advisor) ; Švára, František (referee)
Objective: To calculate glomerular filtration (GF) through the use six available methods to estimate GF and measure impedance parameters phase angle () and fat free mass (FFM) by using multifrequency and monofrequency measurement. Select one method of estimating GF as a strict method of estimation GF for this study and by using linear regression relate with other method of estimating GF and impedance parameters measured () and FFM. Consider if () and FFM are significant parameters to improve methods of estimating GF given below (MDRD-A, MDRD-B, CLCG, CLcysC). (...) Conclusions: Impedance parameters () and FFM correlate with GF, decreasing GF cause decreasing of these impedance parameters. This study proved very close relationship between parameters FFMx and FFMc, obtained by using two different kinds of measuring (R2 - FFMx and FFMc = 0,843). Method of bioimpedance is ready to other validation and to develope bioimpedance scale to estimate renal function.

Artificial neural networks and their application in the assessment of insurance risks
Macek, Karel ; Jiroutek, Pavel (referee) ; Mrázová, Iveta (advisor)
The present work studies applicability of artificial neural networks in the assessment of insurance risk. Structure and function of multilayer perceptrons, Kohonen maps, Fuzzy ART networks, and Fuzzy ARTMAP networks are described. Concept of insurance risk is defined and the ratemaking by generalized linear models is introduced. Neural networks' methods for reduction of input space's dimension, knowledge extraction, and visualization are summed up. Data describing traffic accidents are acquainted and results achieved on them are presented. The work successfully demonstrates theoretically and experimentally that multilayer perceptrons approximate better than generalized linear models. Modification of multilayer perceptron estimated distribution function of total claim. Analysis performed by Kohonen map and by subsequent visualization detected two significant clusters. Analysis by Fuzzy ART network is presented as a part of new algorithm for reduction of input space's dimension. New algorithm inspired by Fuzzy ARTMAP network discovered a group of accidents where the claim is above average. This group is delimited by interpretable rules. Attached CD contains scripts for Matlab and MySQL that was used for mentioned analyses.

Branchial arches region and its blood vessels are extensively transformed in the embryonic development. Aim of this study is to investigate mechanisms of the branchial arches region development and to study how a morphogen Sonic hed gehog (Shh) participate on the formation and remodeling of branchial arches and their blood vessels. Influence of Shh was evaluated based on the changes caused by its inhibition in vivo. Shh function was inhibited with an anti-Shh antibody, which was produced into the embryo from the applied hybridoma cells. Shh signaling cascade was also inhibited by cyclopamine. Results show that Shh is important for dc novo format,ion of the blood vessels in the branchial arches region. Further Shh is necessary for stabilization of the vessel wall, mainly for anterior cardinal vein. Shh also alfects later vessel development and transformation, which includes i.e. fusion of the dorsal aorta, branching of the internal carotid artery and outflow tract development. Short time inhibition of Shh has minor effect on the apoptosis and proliferation activity of the branchial arches region mesenchymal cells. We assume that Shh signals directly to the blood vessels endothelial cells, as Shh receptor ptel is also expressed in endothelial cells and its signal is reduced with Shh inhibition. In studied...

The Possibilities in the Efectivity of the Primary Prevention
Hermanová, Lenka ; Ortová, Marie (advisor) ; Roth, Martin (referee)
Knowledges from different researchers showed necessity to begin with primary prevention activities from childhood. This function has primarily family and home - folks, then preJschool education and schools. This thesis is about possibilities how to make the primary prevention for children and young people more effective. Particular attention is paid on the primary prevention programs in schools. But there are other factors very important beyond these activities. And it is homeJfolks, primarily family and peers but also terms in the society. There are very important protective and risk factors, which prevention tends to enhance or tries to minimise. There are a lot of methods and criterias which are very important in these programs to be consider effective. And it is very important to adapt methods and forms of these programs to the age of individual. There are mentioned information about specificity in class of age, various types of programs and methods in this essay. Further information are about the possibilities and approaches, which are indispensable to achive success in the field of primary prevention school programs. Powered by TCPDF (www.tcpdf.org)

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.
