Possibilities and usage of multimedia communication instruments in practice
Malý, Michal ; Krsek, Libor (advisor) ; Horný, Stanislav (referee)
The main purpose of my work is to describe and chart the possibilities and use of the means of multimedia communication as the title prompts. In the work there is shown their broad variability in use in many different areas. My work is divided into several chapters. At first the reader is introduced into the broad issue of multimedia including definitions and descriptions of individual elements. Then follows an overview of areas where the multimedia material is possible to apply such as in education, households, as well as in work and public places. There is also a sub-chapter about virtual reality. Next my work deals with the ways how the multimedia content is presented to people by which I mean with what technologies and equipment it is spread. An overview of today's trends, new technologies together with a prediction of future development is not missing. The closing part of my work is dedicated to a comparison between theory and practical situation in particular the use of multimedia in the chain stores Baumax.

Managing interest rate risk
Hrouda, Jiří ; Radová, Jarmila (advisor) ; Witzany, Jiří (referee)
Main interest of this bachelor thesis is a management of interest rate risk from the ALM point of view. The goal is to provide a reasonable insight into management procedure as a whole i.e. from theory and measurement to evaluation of interest rate risk. Due to the limitation of extent, hedging of interest rate risk is not treated in the thesis. Real data analysis of interest rate risk is an essential part of the thesis. In the analysis the approaches to measurement of interest rate risk are being used on real data simulating real life interest rate risk measurement procedure.

Application and equation of the multiple-criteria decision making methods at intercompany comparison
Řezníček, Josef ; Kuncová, Martina (advisor) ; Šindelářová, Irena (referee)
The target of this thesis is to compare suitable application methods at intercompany comparison. Used methods are divided into three sections. In the first part, the multiple criteria decision methods are described. Within this part, common used methods (method of simple order, method of standard variables, method of distance from virtual subject) and more advanced methods taught in the class of Theory of decision (WSA, Topsis, ELECTRE III, Mappac and other) are described. As part of these methods the determination preferences are defined. Further Data envelope analyses are introduced. The last method mentioned in the theoretical part is index IN05 method. All of the above described methods are applied to the beer industry. In conclusion the comparison of all used methods is presented.

The meaning of the education in secondary prevention of ischemic heart disease
Adamcová, Jitka ; Tůmová, Andrea (advisor) ; Býma, Svatopluk (referee) ; Prchalová, Eva (referee)
The main idea of my work is to give a comprehensive view of education problems and its meaning in secondary prevention of ischemic heart disease.As the education is all life process it isn't possible to find a complex effect upon further development of ischemic heart disease in such a short time. The theoretical part of my work shows the terms as aterosklerosis, ischemic heart disease, risk factors and education.In the next part I try to find out life style of clients (patients) and their knowledge. I use questionnaire.One part of this questionnaire is a small objective inquiry of a nurse.After 2 -3 months I compare the improvement in particular spheres of life style. 50 clients (patients) of a private cardio surgery have taken part in my research. In the end I can say that even if the results of my research weren't 100 per cent positive at all 50 clients (patients), they show unambiguous contribution of the education in secondary prevention of cardio vascular diseases.

Methods of protection against eavesdropping and snooping in digital networks
Pokorný, Tomáš ; Šalamon, Tomáš (advisor) ; Štorková, Veronika (referee)
The aim of this work is to provide a comprehensive overview of eavesdropping and snooping in digital networks, describe possible threats and show technological and organizational precautions against them. The first chapter introduces the reader into the topic and shows all the main threats. The second chapter describes technological precautions with the emphasis on data flow. The first part of this chapter explains the terminology. Next part tries to solve the security of each type of a communicational channel followed by the virtual private networks issues, physical networks and the risks of encryption. The third chapter analyses organizational issues with the emphasis on legislation. Precautions in this chapter make the technology from the previous chapter more effective. The fourth chapter uses the findings from previous chapters and tries to secure a company in all its complexity. This allows the estimation of total cost. The practical part of this thesis should serve for companies with already developed infrastructure who want a transparent solution that would protect them from eavesdropping and data thefts.

Applications of Multivariate Time Series Models in Finanacial Analysis
Hrba, Martin ; Cipra, Tomáš (referee) ; Zichová, Jitka (advisor)
The thesis deals with the applications of multivariate ARMA models for particular time series from nancial markets; it consists of a theoretical part and a practical part. The former refers to the theory of multivariate ARMA models and methods of their applications. In the latter two time series are solved by system Mathematica 5.0, one currency courses series and one stock exchange index series. The data and programme source code are enclosed on a CD.
