Questions of pollutants determination in waste waters
Tandler, Ágnes ; Čáslavský, Josef (referee) ; Vávrová, Milada (advisor)
In this bachelor thesis of theoretical character is being solved the problem of the presence of harmful substances in waste waters. Concerning inorganic substances attention is focused to lead and cadmium and their compounds. From the wide row of harmful organic compounds are chosen surfactants, polycyclic aromated hydrocarbons and polychlorinated biphenyls. There are described their chemical properties, origin and appearance in waste waters. This work also includes their analytical determination by mobile analysis and confirmatory methods. The last chapter includes standard operating procedure of the confirmatory fotometric method of determination of anionic surfactants, which is suitable for accredited laboratories.

Editing, validation, standardization and preparation for publication of electronic version of an screening diagnostic questionnaire DACH
Šporclová, Veronika ; Niederlová, Markéta (advisor) ; Šípek, Jiří (referee) ; Thorová, Kateřina (referee)
The questionnaire DACH was created within the pilot survey of the dissertation project of PhDr. Kateřina Thorová, Ph.D. Since it was put into practice, the questionnaire has become a relatively common tool used in the diagnosis of Autism Spectrum Disorders. The theoretical section of my dissertation introduces the reader to the wider context of Autism Spectrum Disorders - from ethiology to treatment (therapy). The empirical section then focuses on editing, validation and standardization of the DACH questionnaire created by Thorová. Empirical testing of the DACH was conducted on a sample of 240 people. Statistical analysis of the collected data demonstrated a relatively high level of reliability, sensitivity and specificity of the method, along with a high predictive value of positive results. The correlation between the questionnaire results and the results of the diagnostic assessment with the use of the methods of the "golden standard" for autism was lower, but can be considered as satisfactory. The main goal of my dissertation is to develop a standardized Czech method for screening early symptoms of autism in children. For wider access of the practical applications of this project, an electronic version of the DACH questionnaire is available, including scoring and general recommendations. The...

Signals of anxiety in drawings of primary school children
ČERNÁ, Adéla
This bachelor thesis deals with the extent of using drawing techniques as indicative screening method for detecting increased level of anxiety and anxiousness of primary school children. The basic terminology such as anxiousness, anxiety and fear are defined in the theoretical part. The thesis focuses on the issue of anxiety and anxiousness of children attending primary schools as well as on using children's drawings as a diagnostic tool with an orientation on human body drawing. Signs of anxiety are described from different point of view of several authors in the last chapter. These signs will be further examined in the practical part. A scale for measuring degree of anxiety and anxiousness was used in the practical part. This scale served as a tool for dividing respondents into three groups. The aim of the survey was to find out the differences in human body drawing tests among respondents of different degrees of anxiety. The groups were compared in these human body drawing tests according to specific defined signs of anxiety. The results of the thesis could support measurability of anxiety signs and usage of drawing techniques in the area of children psychodiagnosis.
