Evaluation of the results and quality of the online district round of the D category of the Geography Olympiad 2020/21
Filipová, Diana ; Jelen, Jakub (advisor) ; Hanus, Martin (referee)
The thesis deals with the analysis of tests of category D (secondary schools) of the district round of the 23rd year of the Geography Olympiad and the evaluation of their quality. In the theoretical part the concept of giftedness and giftedness is defined. At the same time, different approaches to their definition are discussed. In the following chapters, the Geography Olympiad subject competition, its system and structure are presented. The criteria and selection processes that enable selected competitors to represent the Czech Republic at international geography competitions are presented. This is followed by an analysis of the course of the competition during the period of the Covid-19 pandemic and a description of the measures taken to ensure the security and continuity of the competition. Deeper attention is paid to the evaluation of the quality of the test of the district round of category D of the 23rd Geography Olympiad and the analysis of the success rate of the competitors in the individual parts of the competition. Specifically, the parts of the atlas work, the written test of geographical knowledge and the practical part are evaluated. The test problems are evaluated using statistical methods such as Spearman's and Pearson's correlation coefficient, discriminant index and Cronbach's...

Evaluation of the results of the online district Geographic Olympiad 2020/21
Filipová, Diana ; Jelen, Jakub (advisor) ; Svobodová, Hana (referee)
The thesis deals with the analysis of tests of category D (secondary schools) of the district round of the 23rd year of the Geography Olympiad. In the theoretical part the concept of gifted children. At the same time, different approaches to their definition are discussed. In the following chapters, the Geography Olympiad subject competition, its system and structure are introduced. The criteria and selection processes that enable selected competitors to represent the Czechia at international geography competitions are presented. This is followed by an analysis of the course of the competition during the period of the covid-19 pandemic and a description of the measures taken to ensure the security and continuity of the competition. A deeper attention is paid to the evaluation of the results of the district round of the 23rd year of the Geography Olympiad and the success of the competitors in the individual parts of the competition. Specifically, the parts of work with an atlas, the written test of geographical knowledge and the practical part are evaluated. The questions of the district round were analysed in terms of the number of points obtained in each task and part. Subsequently, statistical processing and evaluation of the reasons for success in each task were carried out. At the end of the...

Change of Cephalometric Values Focused on Labial Bone Thickness
Filipová, Diana ; Dostálová, Taťjana (advisor) ; Racek, Jaroslav (referee) ; Špidlen, Miloš (referee)
The morphology of the craniofacial complex is prone to alterations resulting from a wide range of external factors. In the first part of the presented thesis, we analysed the influence of slow long- term changes of the environment and population genome by comparing historical (11-12th century AD) and contemporary skulls using cephalometric X-ray images. The second part focuses on the effects of orthodontic treatment on bone thickness in relevant areas, with the analysis being based on Cone Beam computed tomography. A comparison of the palatal angle of 115 historical and 75 contemporary skulls revealed a statistically significant decrease of this parameter. The follow-up of 58 patients utilizing three- dimensional diagnostic imaging measurements before and after treatment revealed a statistically significant decrease in vestibular bone thickness, without changes of total alveolar width. Our analysis revealed a substantial bone response to respective forces, with relevant clinical implications - respecting the anatomical limits of the range of motion is essential to achieve therapeutic success and to avoid alveolar defects. Keywords: 3D imaging, CBCT, cephalometry, orthodontics, dentistry
