Validation of the Developmental Coordination Disorder Questionnaire for children aged 6 -10 years in the Czech Republic
Vlasáková, Nikol ; Čepička, Ladislav (advisor) ; Dvořáková, Hana (referee) ; Mess, Filip (referee)
Problem: A specific developmental disorder of motor function affects up to one in 12 people. Neither the prevalence of DCD nor its diagnosis is completely uniform. According to some authors, even given the difficulty of existing tests and test batteries, a "gold standard" for diagnosing DCD is still being sought that would most effectively diagnose its prevalence. In Canada, a standardized screening method, the Developmental Coordination Disorder Questionnaire (DCDQ), has been developed as an auxiliary diagnostic tool to help detect DCD in children. It is an exploratory method that uses a questionnaire technique designed primarily for parents and teachers of children to diagnose the prevalence of this disorder. We believe that by using the DCDQ questionnaire, which according to Schoemaker is a "coarse screen" in identifying children with DCD, we will single out children with DCD and suspected DCD. Studies emphasize the importance of early identification of children with developmental coordination disorder (DCD), not only as a prevention of secondary academic, emotional, and social manifestations of the disorder. The questionnaire allows screening of children with motor difficulties. The DCDQ has not been validated in the Czech Republic and this is the aim of this study so that it can be used for the...

Validity of the VO2 Master Pro device for maximal oxygen consumption prediction and the measurement of resting metabolism
Goldschmidt, Tobiáš ; Nohel, Michal (referee) ; Chlíbková, Daniela (advisor)
Measurements of maximal oxygen uptake and resting metabolic rate are one of the most important things in testing athletes and madical patients. For these measurements are used breath analyzers. These analyzers are usually non-portable costly devices. VO2 Master Pro is on the other hand portable breath analyzer with much lower prize. It is biggest disadvantage is that it contains only O2 sensor and not CO2 sensor as madically aproved devices. Aim of this study is to determinate validity and difference of measurements between VO2 Master Pro and reference device for measuring maximal oxygen uptake and resting metabolic rate. Difference for measuring maximal oxygen uptake was 4,15 ± 4,41 %. For measuring of resting metabolic rate difference was 41,20 ± 11,44 %. For measuring of maximal oxygen uptake is VO2 Master Pro valid but for measuring of resting metabolic rate it is not. It was also confirmed, that size of measured value have non-linear corelation with size of difference in measuring maximal oxygen uptake.

Assessment Centre Method Validation - Approaches and Options
Fousková, Petra ; Rymeš, Milan (advisor) ; Záškodná, Helena (referee)
The subject of this thesis is a validation of an assessment centre for employee selection, e.g. examining the validity of this method. Currently, the assessment centre represents an often used method of employee selection. At the same time, however, its implementation is demanding from the financial, time and personal perspective. If the assessment centre shall be considered an effective employee selection method, it is essential to pay attention to its psychometric aspects, especially the validity of its findings. First, the terms "assessment centre" and "validity" are defined and explained. Then, the thesis presents approaches and options of validation of the selection assessment centre based on scientific literature, articles and researches. Key Words assessment centre, employee selection, validation, validity

Correlation of human figure and tree drawings
Matoušková, Tereza ; Klusák, Miroslav (advisor) ; Kučera, Miloš (referee)
This bachelor thesis deals with the figure drawing test and the tree test from the projective point of view, based on the books written by Zdeněk Altman. I focus on the interconnection between these two kinds of drawings. The thesis contains the basic characteristics of these two methods and discussion about their scientific basis. I describe the process of using the books as manuals for drawing analysis. This thesis also contains results of drawing analysis and characterization of their authors. Fifteen adolescents placed in a children's home participated in research. In conclusion, I address the correlation of both drawings.

Processing of Incorrect XML Data
Svoboda, Martin ; Holubová, Irena (advisor) ; Nečaský, Martin (referee)
XML documents and related technologies represent widely accepted standard for managing and exchanging semi-structured data. However, surprisingly high number of XML documents is affected by well-formedness errors, structural invalidity or data inconsistencies. The aim of this thesis is the analysis of existing approaches resulting to the proposal of a new correction framework. The introduced model involves repairs of elements and attributes with respect to single type tree grammars. Via the inspection of the state space of an automaton recognising regular expressions, we are always able to find all minimal repairs. These repairs are compactly represented by recursively nested multigraphs, which can be translated to particular sequences of edit operations altering data trees. We have proposed four particular algorithms and provided the prototype implementation supplemented with experimental results. The most efficient algorithm heuristically follows only perspective repair directions and avoids repeated computations using the caching mechanism.

Reliability of evaluation in selected technical subjects
Konvičková, Hana ; Tvrzová, Ivana (advisor) ; Kasíková, Hana (referee)
v anglickém jazyce Annotation In the theoretical part of my bachelor thesis I deal with the definitions of school evaluation, conception of the current evaluation, types of evaluation, characteristics of evaluation, specifications of the secondary technical school evaluation, as well as the assessment in specialised subjects and reliability of the assessment as the condition of the objective evaluation. The empirical part deals with the level of reliability in the assessment of a set task in the subject - Commercial - Law Correspondence. The written and oral communication and written and electronic communication. The teachers of this subject, at three secondary technical schools in Prague 1, 4 and 9, were asked to give students a specific task and assess it according set criteria. One of the assessors was the teacher of the subject and I was the second one. The reliability was defined as the identity rate of the independent assessment of the same school tasks carried out by two assessors. In the summary I reflect the contribution and drawbacks of the research and the task assessment done by the other teachers and my own assessment. I try to suggest the steps for following the basic rules of criteria in business letters.

The Reliability of Measuring on the Skytec Interactive Ski Simulator
Novotný, Otomar ; Jindra, Matouš (advisor) ; Fořterová, Petra (referee)
Title: The Reliability of Measuring on the Skytech Interactive Ski Simulator Objectiv: The goal of this work is to investigate the reliability of the measurement of energy expenditure on the Skytech Interactive Ski Simulator. Methods: The sample consisted of 14 subjects, among which were 9 boys and 5 girls. The value of energy expenditure was measured by indirect calorimetry using the energy equivalent and respiratory exchange ratio. For the measurement of respiratory gases, the Metamax 3B metabolic analyzer and for the analysis of heart rate, the Polar S610 heart rate monitor were used. The subjects completed two measurements, each lasting 6 minutes. During this time, the data needed for subsequent calculations reliability were measured. Assuming that the pair of measuring has a two-dimensional distribution, the reliability equals the correlation coefficient. It was computed using the maximum likelihood method. Results: The measurement of energy expenditure on the Skytec Interactive Simulator provided consistent and reliable results. The findings in this study can be applied to further testing on this machine. Conclusion: The reliability of energy expenditure reached 0,84, a result better than the usual values of reliability tests, which may typically be about 0,8. Keywords: Energy expenditure,...

Analytical methods for measurement error estimation in survey data
Chylíková, Johana ; Vinopal, Jiří (advisor) ; Kreidl, Martin (referee) ; Buriánek, Jiří (referee)
Analytical methods for measurement error estimation in survey data This dissertation aims at the domain of measurement error in social science survey data. To conceptualize and estimate measurement errors it employs the analytical and theoretical framework that stems from the analytical method of structural equation modeling (SEM) and Classical Test Theory (CTT), extended with the component of the systematic measurement error. This thesis has two goals that may contribute to development and extension of Czech social science methodology. The first goal is to illustrate methods of measurement error estimation, which has not been used for analysis of Czech data yet, and to point out to some problematical aspects of these methods. The second goal is to employ presented methods to obtain new findings regarding the quality of data from Czech surveys. The dissertation presents three empirical studies, each of which uses one of the methods defined within the presented theoretical and analytical framework. First study presents an analysis of reliability of measurement with the Quasi Simplex Model (QSM). It illustrates how to use the model and brings optimistic results regarding the reliability of the Czech EU SILC panel data. In the second study the confirmatory factor analysis model, operationally called...
