Gažo, Ivan ; Brůna, Karel (advisor) ; Marek, David (referee)
The importance of a currency war and its consequences is nowadays a hot topic of all economies around the world. My master thesis is designed to explain this concept, to introduce the main actors of the currency wars, the ways, in which national economies were and are trying to boost and improve their economic situation and highlight the main tools that are usually used by major powers within currency wars. The practical part is divided into three main sub-chapters that analyze the causes and consequences of currency wars, which we have previously witnessed. Analysis of the currency war I. relates to the years 1921-1936, the currency war II. relates to the period around World War II. and the formation of Bretton Woods system, and finally currency war III. relates to last years, when a superpowers like US, China and EU entered the war as a result of economic recessions of 2007.

Impact of digital imaging on practical work of radiographer
MAREK, David
The submitted bachelor{\crq}s paper deals with the impact of digital imaging on the practical activity of a radiological assistant. In 2006, I participated in a professional seminar held by the AURA-GROUP company, which focused on digitalization of modalities in the health service. This topic seemed to be so interesting for me that I decided to find out what their experience were and what the comparison of the analogue and digital imaging would be like from the point of view of assistants working in practice and to find out more about requirements concerning a radiological assistant{\crq}s work both under the analogue and under the digital operation. In the theoretical section, the principle of X-rays is provided together with a small excursion into the history and the method of analogue and digital imaging and current methods of archiving as well. In this section, the current state of radiology is surveyed and the principles of the individual methods, their advantages and disadvantages together with future prospective are described here as well. In the practical section, I decided to verify the hypothesis that the digital imaging is more valuable in practice that the analogue one. Within the framework of quantitative methodology, the method of fact-finding through questionnaire was used. This questionnaire was presented to employees of radiological departments and the results were subsequently statistically processed and evaluated. The research sample was set up from employees working in the radiological departments in the hospitals in České Budějovice and Český Krumlov. For the purposes of this research, I made no difference as far as the individual age categories or educational background or any other criteria are concerned. This means that this selection was not limited in any way and it has, in my opinion, sufficient support both from the theory and practice and thus it has a sufficient testifying value with respect to the knowledge and experience of the radiological assistants subject to the research. The results of this work confirmed the respective hypothesis and it was demonstrated that digitalization has positive impact on practical activity of a radiological assistant for the purpose of post-processing adjustments, X-ray images archiving using the PACS system, and the fact that there is no need of the so-called wet process is particularly beneficial as well. In the summary, we should also see economic advantages, as they are one of The most important criteria for development of new methods of activities in the field of health care at the present time. The fact that the digital method of imaging saves costs relating to films, chemical substances, archiving capacities (rooms and staff) brings substantial savings, which may be utilized for example for the purchase of technologically advanced equipment.
