Glycopeptide resistance in staphylococci
Rozsypálková, Adéla ; Tkadlec, Jan (advisor) ; Balíková Novotná, Gabriela (referee)
The aim of this thesis is to describe the mechanism of the resistance to glycopeptide antibiotics in a genus Staphylococcus, especially in a species Staphylococcus aureus which is common cause of nosocomial infections resulting frequently in expensive and long-term treatment. This pathogen is dangerous due to its ability to acquire resistance to most antibiotics used in a clinical practice. The resistance of these microorganisms can develop very easily due to inappropriate treatment (administration, drug concentration, duration), which, if not detected, could ultimately results in treatment failure and the death of the patient. The vancomycin resistance of S. aureus could be divide into groups according to their values of vancomycin MIC: VSSA, VISA, hVISA and VRSA. Vancomycin intermediate resistance is associated with mutation, e.g., which affect cell wall synthesis. In contrast, VRSA is associated with the transfer of the mobile genetic element with the vanA or vanB operon from genus Enterococcus. This transmission is due to co-infection with both pathogens. Glycopeptide resistance has also been shown to be very common in coagulase-negative staphylococci (CNS), such as S. capitis, which cause infection in preterm infants. Glycopeptide resistance in CNS and intermediate resistance of S. aureus is...

The Immigration Policy of David Cameron between the years 2010 and 2015
Paulíková, Veronika ; Kasáková, Zuzana (advisor) ; Rovná, Lenka (referee)
The immigration has became the main topic in many western countries during several past years. This thesis focuses on immigration policy of the United Kingdom, where immigration represents 12,5 % of the whole population. Namely it deals with immigration policy during the premiership of David Cameron in the years 2010 to 2015. This topic is relatively recent, therefore has not been sufficiently explored. Moreover, attention is usually focused on integration policy; as a consequence thesis should contribute to mapping of actual immigration policy in the United Kingdom. This thesis examines which specific changes in immigration policy have been introduced by the government of David Cameron. Immigration policy is analyzed on base of the new Immigration Act and other documents which amended new law, then on the reforms of visa policy. The main objective of the analysis is to map immigration policy of David Cameron and reveal the specific steps taken by the government. The thesis also examines whether the development of immigration policy changes are applied to all immigrants from non-EU countries, or only to a certain type of immigrants. It also rates the achievement of stated goals of the Conservative Party.

Cancelation of the visa duty for Ukraine and its impact on the Czech Republic
Vondráčková, Dominika ; Mlejnek, Josef (advisor) ; Landovský, Jakub (referee)
The association agreement between EU and Ukraine includes visa liberalization, which brings concerns about the capability of absorbing the increasing migration of Ukrainian citizens in the Czech Republic. The theses aims at showing realistic state of affairs especially through statistics and interviews with members of crucial interest groups connected to migration process. The text is demonstrating that number of Ukrainians in the Czech Republic is significantly raising, but we cannot consider this raise as intractable. The increase directly connected with visa liberalization can be clearly demonstrated at the number of tourists. Looking at the number of asylum applications, growth was not noted which is considered as sign of well-managed liberalization of migration. Significant changes cannot be seen also in the statistics of illegal migration. Nevertheless, members of foreign police agree that they observe increase of illegal Ukrainians but do not have the capacities to arrest them and register as illegal in the statistics. Visa liberalization is not the only reason of the increase of Ukrainians in the Czech Republic. Major influence is the overall socio-economic situation of both countries and especially extremely low unemployment in the Czech Republic, which creates pressure to the employers...

Analysis of the payment card market in the Czech Republic
Tomčík, Alexandr ; Hoffman, Andrej (advisor) ; Fučík, Vojtěch (referee)
The subject of this bachelor thesis is the analysis of availible data on the payment card market in the Czech Republic in years 2001 to 2016. The theoretical part focuses on the history of payment cards and when they first appeared in the territory of the Czech Republic. It further divides payment cards into several groups according to the type or technology used. The purpose of the thesis is to find out how the card market has developed, wheter Visa or MasterCard has the major share of the issued payment cards and to quantify the parameters of non-cash payments in the Czech Republic. Due to the similar level of development of contactless payment in both countries, part of the work is intended to be compared with the Slovak Republic. The last chapter presents current variants of mobile payment in several world countries and available options in the Czech Republic.
