Experiment kit for the law of force
CÍSAŘ, Aleš
This master's thesis deals with the development and implementation of an affordable trolley set intended for the demonstration of Newton's second law in the framework of teaching physics in primary and secondary schools. The aim of the work was to design, manufacture and test an educational tool that would not only be effective and pedagogically beneficial, but also available to a wide range of educational institutions thanks to the use of modern production technologies such as 3D printing. In the theoretical part of the thesis, a review of current pedagogical approaches to teaching physics and identification of key requirements for educational tools focused on physics experiments was carried out. The practical part is dedicated to a specific design and prototyping of the wheelchair set, including the development of associated worksheets and methodological materials for students and teachers. The pilot testing of the educational benefit of the wheelchair set was carried out in different classrooms, where the reactions of students and teachers were monitored and feedback was obtained for further improvement. The results of the testing showed that the wheelchair set significantly improves the understanding of Newton's second law among students and increases their motivation to actively participate in the learning process. This thesis provides a detailed overview of the development, application and testing research of the innovative teaching tool and its significant benefits for teaching physics. The potential of integrating modern production technologies into the development of educational materials and their influence on making quality and interactive education in the natural sciences more accessible is emphasized.

Bankruptcy prediction modelling in the environment of V4 countries
Suchánek, Aleš ; Režňáková, Mária (referee) ; Karas, Michal (advisor)
This diploma thesis is focused on the construction of a new bankruptcy model designed for small and medium-sized enterprises in the construction industry in the environment of the Visegrad Four countries. The first part of the thesis is focused on defining the concepts of bankruptcy, bankruptcy model and their placement in the historical context, followed by a description of selected bankruptcy models, a brief description of the construction industry and an analysis of constuction sector. In the practical part, the reliability of selected bankruptcy models is tested and then a new bankruptcy model is constructed.

Selected aspects of immunopathogenesis of HIV infection
Bartovská, Zofia ; Holub, Michal (advisor) ; Boštík, Pavel (referee) ; Marešová, Vilma (referee)
Introduction: Virus-specific CD8+ T cells are crucial to suppress the viral replication in HIV infection. Their functional status is important as well. Also, the chronic nonspecific immune activation of T and B lymphocytes plays an important role in the immunopathogenesis of HIV infection. Aim of the study: To analyze the frequency and functional status of HIV-specific CD8+ T cells and the expression of nonspecific activation markers on B and T cells in HIV+ patients and to assess the effect of combined antiretroviral therapy (cART) on these parameters. Patients and methods: Our cohort included 80 HIV+ patients: 36 HIV+ patients on cART, 18 patients without therapy, in whom cART was introduced during our study, 9 patients without therapy, 10 patients with primary HIV infection, 3 long-term non-progressors and 4 patients initially on cART, in whom the therapy was discontinued. Control group consisted of 34 HIV- healthy individuals. We examined CD4+ a CD8+ T cell counts, viral load, expression of nonspecific activation markers on T cells and the frequency of HIV-specific CD8+ T cells by ELISpot method and flow cytometry using MHC tetramers and intracellular cytokine detection. Results: No significant differences in HIV-specific CD8+ T cells were found between treated and untreated HIV+ patients. The frequency...

Analysis of failed studies at universities in the Czech Republic
Ptáčková, Veronika ; Mazouch, Petr (advisor) ; Hulík, Vladimír (referee)
The master thesis deals with failed studies at universities in the Czech Republic. The first part is focused on literary research, on explanation of theoretical terms and on statistical methods, which are subsequently applied in the analytical part. These are decision trees and logistic regression that helped to determine the influence of factors on studies without graduation. The aim of this master thesis is to find significant factors, to compile a profile of failed students and to suggest the measures which could reduce their elimination from tertiary education.
