Risk Management of Bank Credit System and Decision Making Process
Skovajsa, Radek ; Kryštof, Zdeněk (referee) ; Čižinská, Romana (advisor)
The theoretical part of this thesis describes the development of Czech banking sector, especially with emphasis on post-revolutionary rebirth within the new conditions of market economy. The following part demonstrates the decision-making credit account process of a bank on a particular case study based on the methodics and procedures leading up to maximal elimination of credit risk. At the same time, the author presents a partially modified internal opinion on a decision of particular business transaction. It is accented that every decision of a bank must comply with the regulations of CNB. The conclusion of the thesis affirms the maximal efforts of domestic banks to minimalize risks within their decision-making credit account processes, which is mirrored in current stability in the development of Czech banking sector.

Study of Formation and Elimination of Acrylamide in Food Matrix during Heat Treatment.
Marková, Lucie ; Jarošová, Alžběta (referee) ; Buňka, František (referee) ; Šimko, Peter (advisor)
Acrylamide (AA) is a probable human carcinogen and undesirable contaminant which is produced by the reaction of reducing sugars with asparagine in plant foods during their thermal treatment above 120 °C. AA is most often determined by GC-MS and LC-MS/MS in isolates from the matrix in a wide range of foods. According to our observations, AA intake from food is higher among young people (from 1.8 to 3.8 µg/kg bw/day), which is consistent with the estimations of JECFA FAO/WHO from the year 2006. Considering the health risk, it is recommended to reduce AA formation in food during its processing, in particular exploiting the available experience. The aim of this thesis was to extend the knowledge of the possibility of AA elimination in selected types of thermally processed foods. The study was focused on cereal foods that contribute significantly to AA exposure, especially bread and sweet biscuits. The whole AA content in the bread is in the crust, which represents 5-15% of the bread. Crust of home-made bread contains approximately 30-75 µg/kg, however the marketed bread contains 2 to 10 times more of AA. This is due to the composition of bread mix, preparation conditions and baking. For maintaining the quality of home-made bread during the dry mixture shelf-life, optimization of bread mixtures was designed by increasing of yeast content, which proved positive effect on the reduction of AA content at sufficiently high activity of the yeast. Monitoring of AA content in assortment of sweet bakery products showed higher levels of AA in diabetic biscuits containing fructose instead of sucrose. Three of them even exceeded the reference value (500 µg/kg) more than 1.5 times for commodity "cookies". Elimination of AA by applications of the enzyme asparaginase has been designed for minimal interference in technology of their production. The concentration of the enzyme and the appropriate method of its use in industrial environment have been tested previously in model systems. In optimized conditions of the enzyme application, AA content in diabetic biscuits was reduced by more than 40% without affecting the organoleptic properties of the final product. Effect of the antioxidants on AA formation was also part of the study. AA content in gingerbread was reduced efficiently by the use of fennel, anise, cloves, vanilla and white pepper (by about 9-21%). Conversely, coriander and cinnamon significantly increased its content (by 18-54%). Since correlations between the DPPH• radical quenching activity of the spice extracts and AA content was not observed, the final content of AA was probably influenced by the chemical composition of spices and reactivity of the individual components in the matrix. Investigated methods appear to be suitable ways of elimination AA in some foods; however their specific use must be optimized with regard to the composition of the food, processing and the technology used. Estimated impact of application of the above-mentioned methods to the overall elimination of AA exposure showed that its intake in high school students from the Czech and Slovak Republic can be reduced on average by 10%. This decrease is a success to reduce the possible risk of cancer disease by eating foods with a high AA content. It is also important piece of information for food producers for further development of relevant methods for AA elimination which would help to reduce the AA intake from foods even more.

Effect of additives on acrylamide content in thermally treated foods
Marková, Lucie ; Ciesarová, Zuzana (referee) ; Šimko, Peter (advisor)
Acrylamide is an undesirable carcinogenic component of thermally processed foods being formed from reducing saccharides and asparagine. In this work, the effect of ammonium and sodium raising agents themselves or in their combination with L-asparaginase enzyme catalyzing the conversion of asparagine into aspartic acid resulting in the reduction of acrylamide in gingerbreads was studied. Also, the influence of selected inorganic salts on the content of acrylamide in a model matrix simulating a composition of cereal products was observed. Simultaneously, the impact of these salts on activity of L-asparaginase was examined to find optimal conditions for its application in cereal technology. Based on experiments it was found, that addition of L-asparaginase reduces acrylamide content by 40 % while inorganic salts addition decreases acrylamide content in the range of 30 - 99 % when the most effective compounds were NH4Cl and CaCl2.

Příčiny eliminace koní ve vytrvalostních soutěžích a jejich prevence
ŠVARCOVÁ, Jana
The aim of this work was to acquire, process and evaluate information about the most common reasons for the elimination of horses from endurance competition races in the Czech Republic. Information about the veterinary status of horses was obtained from the main judges of various horse races held in the Czech Republic, from the horses' endurance cards, which record the factors evaluated during the competition itself, and where it is possible to find out what worsens most often, and how the cause manifests itself. Veterinary cards of individual horses and races were chosen randomly. The veterinary cards were evaluated with the aid of a full text commentary, giving detailed descriptions of each worsened factor, including their frequency. It was then suggested how problems could be avoided. Individual data was summarized, and the differences between individual groups of competitions were expressed. Based on the analysis of veterinary cards from participating horses in endurance competitions, recommendations were made on how to prevent problems, and what specific problems the riders should consider during the race. The most serious and common problems of horses in terms of endurance are described. It was found that the most common reason for the worsening of horses in endurance races is the factor known in Czech as "Chody", or Lameness. The most frequent deteriorating factor in veterinary controls was with the Mucous Membrane. In more than 80% of horses, more than two factors worsened during the race, which did not improve during the race in any way, but often even worsened. Many factors affect deterioration, from training and preparation of the horse, to the knowledge of the horse itself. The results show that most riders in the Czech Republic are not sufficiently informed. There is insufficient care for horses during endurance races. The riders are not experienced enough to prevent injuries or deterioration of the horse's health resulting in exclusion from races.
