Combination of simulation methods and methods of multicriterial decision while purchasing mobile tariffs by companies.
Millová, Terézia ; Kuncová, Martina (advisor) ; Digoň, Daniel (referee)
Because of the high penetration of private market, mobile operators are forced to focus on the services offered to another customer segment. Recently, corporate customers are seen as a promising segment and the competition within this segment is rising significantly. The growth of the competition and offer enhancement force companies to understand the decision making process in purchasing mobile services as much as possible. It is not only time consuming but also financially demanding for management even in small firms. This decision making process, that the companies go through, is the main topic of this Master Thesis. Main goal is neither to choose particular vendor of the mobile services nor to choose particular mobile tariff from the recent market offer but to inform about possibilities proposed by mathematical methods in the decision making area. In the Master Thesis different methods are suggested, compared and combined with the target to enable companies to make the right decision concerning their specific requirements.

Study of factors influencing the function of MntH, membrane transport protein of E. coli
Jurková, Ingrid ; Urbánková, Eva (advisor) ; Krůšek, Jan (referee)
MntH belongs to the Nramp family of transport proteins, and plays an important role not only in homeostasis of iron and manganese, but also in bacterial defence against the immunity response of an infected host cell. MntH co-transports divalent metal ions into the cell together with protons with a stoichiometry dependent on the membrane potential and extracellular pH. Using the redistribution potential dye diS-C3(3), we measured the effects of MNTH expression and MntH-mediated metal transport on the cell membrane potential and intracellular pH. Cells expressing MNTH were found to be hyperpolarised and their membrane potential was depolarised upon the addition of metal ions. In the theoretical part of our work, we explored general four-, six-, and eight-state carrier models that were modified by introducing the voltage dependence of all rate constants. Using mathematical modelling, we simulated the effect of various model parameters (including membrane potential, substrate concentration, and carrier or substrate charge) on substrate influx. We observed some of the transport characteristics described for MntH proteins such as variable symport stoichiometry that is influenced by the membrane potential and pH. However, for a more detailed simulation of the eight-state carrier model, more information about...

Opportunities and limitations of psychological work with "fleet car" drivers
Špryngarová, Jana ; Wagnerová, Irena (referee) ; Štikar, Jiří (advisor)
Traffic safety problems are often discussed and researched, especially recently. Psychology plays an irretrievable part in solving these problems. Submitted diploma theses focuses on specific segment of these problems, the area of the traffic safety related to drivers, who do not have the driving as the main scope of employment, though they need a car to perform their work - fleet car drivers. Emphasis is placed on definitions of the key-terms and summary of theoretical pieces of knowledge, taking in consideration that the issue has not been researched extensively. In practical part of the thesis the opportunities and limits of the work with fleet car drivers are discussed. Pieces of knowledge that aroused from the thesis lie in the area of mental capacity of the fleet car drivers, in the area of general approach to trainings at the hands of the employers and also in the area of the administration of the records regarding the accidents (above all for the purposes of their importance for the subsequent work on raising the safety of fleet car drivers). As the most important result from diploma it appears the project for specialists from different areas, mainly from the area of traffic psychology, to enter the problems of fleet car driving with more urgency.

HRDLIČKOVÁ, Tereza
The final thesis deals with an application of project within history lessons at secondary grammar schools of the Administrative Region of Ústí nad Labem .The thesis summarizes the basic theoretical findings on a projects realisation together with findings gathered by the empirical research at secondary grammar schools of Administrative Region of Ústí nad Labem. The research focused on recognising a present status of incorporating and using projects in the history lessons, and on the experience of pupils and teachers with this specific teaching strategy. On the grounds of connecting these findings, the thesis provides the reflection of possible using of projects in the course of history lessons (not only as a supplement of ordinary lessons). The thesis recognises a present status of projects realisation within history lessons, including the favoured topics, a way of realisation, outcomes, and a brief summary of particular projects offered by external organisations. The thesis deals with positives and negatives of projects realisation in accordance with opinions of pupils and teachers of secondary grammar schools of Administrative Region of Ústí nad Labem. The thesis also contains two proposals of history projects that might be used by teachers for creating their own projects.

Inlflation and risks in evaluation of PPP projects
Mora, Igor ; Valach, Josef (advisor)
Thesis focuses on issues of inflation and risks in evaluation of PPP projects. It sets the basic assumptions and standards for risk identification and administration in PPP projects and furthermore discusses their impact on Value for money and Availability payment. The thesis sets the basic rules for incorporating the inflation and risks into the PPP alternative and sets the rules for economic evaluation of PPP against PSC alterantive (Public Sector Comparator). For the illustration a hypothetical project of construction of primary and secondary schools has been worked out. For the evaluation of economic impact and selection of PPP vs. PSC alternative a standard financial model has been prepared. It focuses on analyzing the Value for moeny and seting up the Availability payment.

Property tax administration and local taxes
Pribulová, Lucie ; Sedmihradská, Lucie (advisor) ; Sedmihradská, Lucie (referee)
My bachelor's thesis describes tax collection and discusses the problems of property tax administration. I analyzed how the municipality goes about collecting local taxes, I described what part of municipality revenues is made up from the local taxes and as an example I introduced the town of Česká Kamenice. Moreover, I indicated the effectiveness of the tax offices in the collection and recovery of property tax and how large the proportions of this revenue are compared to the total tax revenues. I also show the development of collections of this tax on a nationwide scale, as in the case of the Finance Office in Děčín. In conclusion, I have considered the choice of property taxes to be collected by the municipality and what consequences would result from this situation. I compared all the positives and negatives of this amendment and believe that by strengthening the powers of municipalities the system of tax collection would become more efficient.
