Study of geographical authenticity of Moravian white wines
Horáková, Kristýna ; Křikala, Jakub (referee) ; Diviš, Pavel (advisor)
The aim of this bachelor thesis was to verify geographical autenticity of Moravian white wines based on elemental analysis. This data were completed with the analysis of organic acids, fenolic compounds and atioxidants in wines. There were used two spektrometric methods for the elemental analysis (ICP-MS and ICP-OES). The concentration of organic acids was mesured by Ion chromatography. To determine the concentration of phenolic compounds in wines there was used the high performance liquid chromatography (HPLC-DAD), the content of antioxidants and the total content of phenols was measured on spectrophotometer. In total there were 33 samples of wine from 4 Moravian subregions. For the purpose of determination the samples in groups the dataset was firstly corrected by Grubbs test for remote results. From those data the box plots were created which represents the minimal, maximal and mean concentrations of each measured component. Furthermore the analysis of variance was applied, which picked up 12 statisticly valuable parameters from the whole 47. By appliyng the multidimensional statistical methods (Pearson correlation analysis (PCA) and discriminant analysis (DA)) were compiled mathematical models for the division of Moravian wines according to geographical origin. The success rate of the discrimination test was 96,97%. The cross-validation test showed an 81,82% success rate for classifying unknown samples.

Analysis of substances potentially dangerous to humans found in lipsticks
Horáková, Kristýna ; Kučerová, Simona (referee) ; Diviš, Pavel (advisor)
The diploma thesis deals with the determination of the content of risk elements and parabens in lipsticks and the assessment of possible negative effects on human health associated with the use of lipsticks. Parabens were analyzed by high performance liquid chromatography with diode array detection (HPLC-DAD). Aluminum, cadmium and lead were analyzed on an inductively coupled plasma mass spectrometer (ICP-MS). The mercury content was determined using an atomic absorption spectrometer with an UV detector (AAS-UV). A total of 36 lipstick samples from 22 cosmetic brands were selected for analysis, with a savings price in the range of CZK 50–1500. Based on the measured metal concentrations, the hazard quotients (HQ) for individual metals as well as the total hazard index (HI) for the sum of all metals were calculated. Metal concentrations in lipsticks were further processed using Kruskall-Wallis Anova to divide samples according to price categories. The relationship between the content of individual metals and the purchase price has not been proven. Furthermore, a Kolmogór-Smirnov test was performed on these data to compare groups with vegan and not vegan composition. The content of aluminum, which was about 2.5 times lower in vegan cosmetics, proved to be statistically significant for this distribution. Parabens were detected in the minimum number of lipsticks examined, but in some cases information on the content of parabens was missing on the product packaging.

Reflection of dreams in the creative expression of the artist in the context of the application art therapy procedures
HORÁKOVÁ, Kristýna
The topic of the bachelor thesis is a reflection of dreams in the creative expression of an artist in the context of the application art therapy procedures. The thesis is divided into a theoretical and practical part. The theoretical part deals with the charakteristics of dreams, the motif of dreams throughout the history of visual arts, and subsequently presents the work with dreams within the framework of an art therapy approach. The practical part is devoted to the anylysis of selected visual artifacts on the theme of Dreams or Last night I had a dream, with the aim of presenting the use of the interpretive potential of this theme in projective-interventional art therapy.

Fairytales and their potential in the development of emotional competencies in preschool children
HORÁKOVÁ, Kristýna
The theme of this Bachelor Thesis is Fairytales and their potential in the development of emotional competencies in preschool children. The paper is divided into two sections, theoretical part and practical part. The theoretical part describes characteristics od fairytales, the topic of emotional intelligence and subsequently presents emotional competence in preschool children. The practical part is devoted to the analysis of fairytales in order to present which fairytales can contrubute to the development in emotional compentencies of preschool children. Selected fairytales demonstrate their potential application to children with different types of temperament or for solving various emotional difficulties or problems that may affect a preschool child.

The Analysis of school lists of literary works for oral maturity exam in the Czech language and literature
Horáková, Kristýna ; Brož, František (advisor) ; Králíková, Andrea (referee)
This thesis analyses reading lists composed by secondary schools in school year 2016/2017 for the purposes of common general part of maturity exam - oral exam from Czech language and literature. The thesis creates basic material for exploring the form and development of state maturity exam. Reading lists are put into context with literary theoretic conception of canon as the thesis touches upon literary science, pedagogy and didactics. The thesis proceeds from general analysis of literary canon to functions and forms of canon (school canon and maturity exam canon). Then it concentrates on documents, which were available to students taking the maturity exam. The thesis carries out research on collection of 461 secondary schools that offer studies completed by maturity exam. It is followed by presentation of obtained data, verification of its correspondence to binding criteria defined in Katalog požadavků zkoušek společné části maturitní zkoušky (document specifying requirements for common general part of maturity exam) and comparison of obtained data with available sources from school and literary background. The conclusions reveal the content of given part of maturity exam and are set into context of current knowledge of academic and professional society. Keywords Reading lists, maturity exam,...
