The effect of hop on the growth of facultative pathogenic bacteria
Vaníček, Jiří ; Buchta, Vladimír (advisor) ; Jílek, Petr (referee)
Charles University in Prague Faculty of Pharmacy in Hradec Králové Department of Biological and Medical Sciences Author: Jiří Vaníček Supervisor: doc. RNDr. Vladimír Buchta, CSc. Supervisor specialist: doc. MUDr. Pavel Čermák, CSc. Title of Diploma thesis: The effect of hop on the growth of facultative pathogenic bacteria Background: The aim was to determine the sensitivity of selected strains of anaerobic bacteria (Bacteroides fragilis, Clostridium perfringens, Clostridium difficile) to compounds isolated from hop extract (α-bitter acids, β-bitter acids, xanthohumol). Method: To determine the minimum inhibitory concentration (MIC) of anaerobic strains used in the macrodilution method, known as Schaedler Broth, to which were added isolates from hop extract. Minimal bactericidal concentration (MBC) was determined at Schaedler blood agar and Columbia blood agar. Results: The research carried out demonstrated inhibitions within all the selected strains. The measured concentrations of MIC and MBC moved subsequently within the ranges: α-bitter acids 1024 -128 mg/l β-bitter acids 527 - 4 mg/l xanthohumol 128 - 8 mg /l Conclusion: The results obtained showed xanthohumol to be the best. All strains tested showed low and stable xanthohumol MIC and MBC values. From the bitter acids, only beta acids reached...

Geometric problems solvable without calculations
Divišová, Barbora ; Vondrová, Naďa (advisor) ; Vaníček, Jiří (referee) ; Jirotková, Darina (referee)
Title: Geometric Problems Solvable without Calculations Abstract: The thesis focuses on geometric problems which are usually set with a picture and ask for some numerical value. They are solvable by a geometric strategy, i.e., strategy with a small involvement of calculations. Their difficulty lies in the necessity to distinguish partial configurations in the picture. The goal of the research was to describe pupils' solving strategies and find out if they are age dependent. The theoretical background of the thesis consists of the concepts of visualisation, roles of pictures in geometry and their understanding by pupils and the ability to see in geometry. In the pilot study, tasks of the given type were selected for the main study. In the first phase of the main study, three problems were used with 9 pupils of different ages in semi- structured interviews with the goal to get an insight into the solving strategies and their characteristics and look into the influence of prepared hints on the pupils' solutions. In the second phase, 125 pupils aged 12 till 19 solved independently one problem while in the third one (which was a methodological compromise between the previous two), 130 pupils aged 12 till 19 solved two problems independently but had an opportunity to get hints and could explain their solutions...

Floristic and plant ecological characteristic of Vinca minor in the Bohemia, Czech Republic
Vaníček, Jiří ; Karlík, Petr (advisor) ; Jurasová, Vladimíra (referee)
Questions: Are the forest stands with occurance of Vinca minor different from similar surrounding vegetation? What is the effect of presence of V. minor on species composition and species richness? What is the influence of former settlement on species composition and content of metals in soil?
Lokation: Central Bohemia (Czech Republic)
Methods: Forest vegetation with occurence of V. minor and similar surounding vegetation was sampled in 17 lokalities in Central Bohemia usig 200 m2 relevés. For each site including 3 relevés soil pH and soil content of metals were measured. Totaly 111 relevés were recorded. 57 of them with occurence of V. minor were classified using TWINSPAN classification. Recorded ecological variables were tested using canonical corespondence analysis (CCA).
Results: The cover of V. minor is positively corelated with soil pH value (p=0,005). There were no significant differences between stands with and without V. minor. The Ellenberg indicator values for moisture and nutrients were higher at places settled in the past. Most of the well-preserved stands with V. minor were in mesic oak-hornbeam forests (all. Carpinion-betuli). Conclusion: The V. minor seems to be a good indicator of former settlement. It grows mostly in places where it was planted in the past and it colonizes new sites either slowly or not at all.

Analysis of Economic Indicators Using Statistical Methods
Picka, Václav ; Vaníček, Jiří (referee) ; Doubravský, Karel (advisor)
The thesis is focused on the analysis of economic indicators of Brno Transport Company, Inc. using statistical methods. The issue of time series, regression analysis and selected economic indicators is illustrated in the theoretical part. In the practical part the indicators will be analyzed using time series and regression analysis associated with their predictions for the future. The last part contains recommendations for possible determination of strategies and business objectives.

Design of a Destination Card for Toulava Region
Drábová, Martina ; Jarolímková, Liběna (advisor) ; Vaníček, Jiří (referee)
The aim of this diploma thesis is to design a destination card for Toulava region. This region is located on the border of Central and South Bohemia. Theoretical part of the thesis is focused on theory of destination management and marketing. Destination cards are broadly speaking packages of tourism services, so the first part deals with this term a lot. Next chapter is focused on destination card principles and best practices in this field. The second part of the thesis occupies with an analysis of internal as well as external environment of the Toulava region. The last chapter deals with a design of the destination card itself and it is based on findings from previous chapters.

Čulíková, Veronika ; Valentová, Jana (advisor) ; Vaníček, Jiří (referee)
The diploma thesis aims at the creation of a new thematic product, namely for the destination of South Bohemia. The thesis is divided into two parts where the theoretical part defines terms related to the topic of the thesis first and deals with the destination marketing and the process of creating tourism destination product. In the practical part, there is, based on performed analyses, designed the product concept, the sense of which is wandering around places which South Bohemian folk songs are about. At the end, the benefits of the designed thematic product are predicted and its potential is evaluated.
