CT X-ray quantitative evaluation
Novotný, Lukáš ; Malínský, Miloš (referee) ; Drastich, Aleš (advisor)
X-Ray Computed Tomography is irreplaceable medical imaging system. Quantitative evaluation is day to day routine used for clean run of this imaging system. The master’s thesis is focused on quantitative evaluation of first and third generation X-Ray CT. First of all is about subjective and objective evaluation of space and energetic resolution. Space resolution is evaluated in space and frequency domain. Energetic resolution is represent by low contrast resolution method. Application “Kvantitativní hodnocení kvality CT RTG zobrazení” created for this thesis is used for creation of reconstruction image and quantitative evaluation. This application was created with consideration of its usage in subjects about image processing. The master’s thesis contains results of quantitative evaluation X-Ray CT created with this application and proposal of lab work.
A comparison of teachers' attitudes towards qualitative and quantitative assessment before and after the Covid-19 pandemic
Výborná, Andrea ; Laufková, Veronika (advisor) ; Novotná, Kateřina (referee)
The aim of the diploma thesis is to analyze a sample of 46 Czech first-grade pedagogues, whether there was a change in their perspective on verbal assessment after distance learning due to the Covid-19 pandemic. This work is divided into two parts. The introductory part of the first, theoretical part contains information from scientific publications regarding the concept of assessment in general, its functions, its types and forms. In the next part, the theoretical part deals with quantitative and qualitative assessment with an emphasis on their influence on the student's motivation. In the second, practical part, I compared the results of 2 researches carried out by me in the form of a questionnaire. One was implemented in 2020 and the second, enriched with 2 update questions, was implemented in 2023 on the same sample of respondents. The conclusion of the thesis contains the answer to the question posed at the beginning of my diploma thesis. From the data collected from my 46 respondents, it appears that educators' views on verbal assessment did not change significantly after distance learning during the Covid-19 pandemic, although there was a slightly more positive perception of verbal assessment.
