Benedikovičová, Petra ; Nečadová, Marta (advisor)
The aim of my diploma thesis is the macroeconomic analysis of the Visegrad Four countries after joining the EU, which will be evaluated in the international context. It will be assessed on three levels, both in terms of economic performance of V-4 converging countries, based on Eurostat statistical data and the Czech Statistical Office. At the second level, it will be assessed in terms of multi-criteria evaluation of the Global Competitiveness Report, which in addition to hard statistical data, is working with soft data as well. At the third level, the Competitiveness will be evaluated in terms of innovation performance, based on an evaluation tool of EU Innovation Union Scoreboard.

Classicist gates and doors in Polička
Junek, David ; Konečný, Lubomír (advisor) ; Macek, Petr (referee)
The houses doors and gates belong to discreet, but very significant monuments. There were more than 12 joineries in Polička, where 85 carved gates and doors were made during the period 40 - 80 years in 19th century and they were unique in whole Czech republic. 35 of them have preserved. Classicism appeared in Bohemia during the reign of kaiser Joseph II. (1780 - 1790) and it entered to Polička in 1841, when the buildings of schools for boys were built and faded until the eighties. The big town fire in 1845 caused outstanding classicist reconstruction. The publication treats on following topics very closely: The submitters - citizens of Polička - decorated gates were an subject of reputation. The joiners - there are the detailed lists of the masters and descriptions of their hoboes journeys. Construction of the gates and doors. The motives of decoration. The colour scheme of the gates and facades - the most common gate colours were ochre, brown and green - gate dichromatism is much modern. The door hammering including handles and locks - about locksmiths work, many cast-iron handles came from the iron-foundry in Blansko (it was one of the 5 most important iron-foundries in Austro-Hungary). The stony gantries - undecorated, made from sandstone or hard gneiss: gantries were painted by same colour as the gates....

Diagnostics of diabetes mellitus in adults including pregnant
ŠTĚRBOVÁ, Eva
Diabetes mellitus is worldwide spread chronical disease which affects both sexes and all age groups. If the disease is not treated it can cause hard damage to various systems or even kill. The thesis is divided into two parts. The objective of the first, theoretical part, was to bring closer the problems of diabetes mellitus, its classification and complications. Simultaneously, the possibilities of laboratory diagnostics of the disease were described. The objective of the second, empirical part was to assess if glycohemoglobin was a suitable compensation of oral glucose tolerance test as a marker of impaired glucose tolerance. For the thesis the data of 94 patients investigated at the Laboratory of Clinical Chemistry in Nemocnice České Budějovice, a. s. (Hospital České Budějovice Inc.) were used. The patients were divided into two groups: the group called ``Pregnant{\crqq} (51 pregnant women) and the group called ``Others`` (43 people). In both groups oral glucose tolerance test was carried out and glycohemoglobin was determined. The level of glucose in blood was determined by a fotometric enzymatic method at the analyzer ADVIA 1650 Chemistry system, glycohemoglobin was determined by effective liquid chromatography at the analyzer TOSOH A1c 2.2 (HLC 723 Ghb V, G5). The group of pregnant cannot be reliably evaluated because only one woman was diagnosed gestational diabetes mellitus according to oral glucose tolerance test. In the group of Others impaired glucose tolerance according to oral glucose tolerance test was proved in 14 individuals, 5 of them had increased glycohemoglobin and 9 individuals had glycohemoglobin in referential range. Diagnostic sensitivity, specificity a effectiveness at cut off 4,0 % was counted for glycohemoglobin. Sensitivity was 36 %, specificity 96 % and effectiveness 73 %. The results show that the use of oral glucose tolerance test as a marker of impaired glucose tolerance is still more suitable than the use of glycohemoglobin which does not have sufficient sensitivity for the diagnosis of the disease.

Králík, Petr ; Hála, Michal (referee) ; Mrňa, Libor (advisor)
This thesis deals with research of cutting defects at laser cutting of 15 mm thick carbon steel by Bystronic fiber laser with emphasis on wide cutting gap, which causes enlargement of wide of cutting gap and deterioration of roughness of cutting edge and increase of creation fo heat. The introduction describes the main types of lasers used for cutting sheet of metal and compare their advantages and disadvantages. Also described is a cutting process and its parameters, and also the possible cutting defects. An experiment was conducted on steels S355MC and S235JR and cutting defects were analyzed in relation to the set of cutting parameters. Next part determines the extent of the recommended parameters that should be chosen for specific cutting conditions and is balanced recommendations regarding the choice of material to be cut, and technological adaptations parts. In the last part is measured roughness of a wide cutting gap, the width of the heat affected zone and micro-hardness of the material.

Maňas, Petr ; Kaván, Martin (referee) ; Mrňa, Libor (advisor)
Experimental work evaluated the dependence of the thickness of the cutting edge, its roughness and assessment of appearance with regard to the defects resulting from the diameter of the focal spot during oxidative cutting Yb:YAG laser. Other variables include the experiment: process parameters such as laser power, cutting speed, oxygen pressure and focus position. Experiment is based on the Taguchi tables. Test samples were cut off from sheet thickness 10, 15 and 20 mm. Representatives of conventional steel were S235JRC+N, S235JR, S235JR+N and steel type RAEX developed for laser and plasma cutting. Samples were evaluated according to the ČSN EN ISO 9013. The evaluation of samples was into classes according to standards of quality. Hardness measurements were performed on the samples thickness 20 mm of convectional steel and steel type RAEX.

Assessment of the state of wood in the construction and evaluation of the usefulness of non-destructive testing methods
Munduchová, Markéta ; Vaněrek, Jan (referee) ; Brožovský, Jiří (advisor)
This bachelor's thesis consists of theoretical and experimental part. In the theoretical part there are given findings regarding on structure of wood, its basic properties and durability. The following describes the wood defects, influence of wood pests and fungi, types of wooden structures, climatic conditions, chemical corrosion and mechanical damage to the wood. Evaluation of the status of wood in the structures is appropriate by using non-destructive methods, therefore was performed research articles on these methods. Non-destructive methods are used: visual, hardness tests, electrical, radiation, optical and moisture determination. Experimental part of the bachelor's thesis is focused on ultrasonic impulse method, that can detect defects or damage in the wood mass that depends on the speed of ultrasonic impulse. For a reliable interpretation of the results it is appropriate to combine non-destructive methods when assessing status of wood structure.

Charles University in Prague, Faculty of Pharmacy in Hradci Králové Department of: Pharmaceutical Technology Candidate PharmDr. Sylva Klovrzová Supervisor doc. PharmDr. Zdeňka Šklubalová, Ph.D. Title of Doctoral Thesis: Formulation of extemporaneous paediatric liquid preparations in the hospital pharmacy In the paediatric population, oral solutions and/or suspensions represent a suitable alternative to preparation of hard capsules in the pharmacy. This thesis aims at formulation of stable liquid oral preparations with cardiologic drugs, propranol- hydrochloride, sotalol-hydrochloride and furosemide, for the children aged from newborn to approximately 6 year. At the formulation of the preparation compositions, the simple routine preparation in a pharmacy was the main target as well as the use of excipients safe for paediatric population in the minimal necessary amount. Using a high performance liquid chromatography, chemical stability of the active ingredient and, simultaneously, the preservative was determined in all formulated preparations stored at two different temperatures at time points over minimum 180 days. In order to achieve this, the specific analytical methods were developed and validated at the department of Analytical chemistry, Faculty of Pharmacy in Hradec Králové. However, the...

Administrative delicts of legal entities
Kareta, Jan ; Prášková, Helena (advisor) ; Kopecký, Martin (referee)
72 10. Resumé Liability of legal entities is a actual issue which is broadly discussed not only in the Czech republic in the connection with criminal law reform but in the whole Europe. According to the international treaties and also as a result of internal interest each state has to find its way to be able to impose effective and deterring sanctions towards legal entities in the the case of breach of public law. This thesis describes the Czech system of public liability of legal entities which lies within the administrative branch of law, its difficulies and suggests how it could be partialy improved. Current state of the law of liability of legal entities suffers from numerous imperfections, defects and from the absence of general arrangement. The most important challenge which lies before the Czech legislatives is to deside if the public law liability of legal entities stays within the reach of the administrative law and will be just altered and impoved partialy or if it shifts to the penal law. This question is very hard to respond, because the traditional continental criminal law is on one hand based on the principle "societas delinquere non potest", which means that the legal entity is not able to possess a guilty state of mind (or mind at all) and on the other hand it is based on the principle of...
