A proposal and manufacturing of temporary dental restoration
Jiroušek, Jan ; Sliwková, Petra (referee) ; Sedlák, Josef (advisor)
This bachelor thesis deals with manufacturing of temporary dental restoration. Theoretical part contains an overview of types of dental restorations and their division, Furthermore it states important properties and division of the dental materials used nowadays. The next point of theoretical part is an overview of the technologies of dental restorations manufacturing used at present. Practical part is aimed at manufacturing of temporary dental restoration by using the digitization by intraoral scanning, design of restoration in CAD software and CAD/CAM manufacturing. The thesis is concluded with discussion comprising a summary and evaluation of the results of single steps from practical part.

Analysis of mechanical properties of plastic samples produced by 3D printing technology
Jiroušek, Jan ; Joska, Zdeněk (referee) ; Sedlák, Josef (advisor)
The master's thesis deals with the determination of mechanical properties of materials used for 3D printing (PLA, PETG, ABS, ASA). The theoretical part contains characteristics of polymer materials and describes testing of mechanical properties and additive technologies. In the experimental part, the standardized samples produced by the technology Fused Filament Fabrication were analysed using mechanical tests (tensile test and hardness test). Some of the examples were exposed to the selected factors of degradation. Selected parameters from mechanical testing (tensile strength, modulus of elasticity in tension, elongation and Shore hardness) were statistically processed. The conclusion of the thesis evaluates the impact of the factors of degradation on particular materials and compares them subsequently.

The status of municipalities with extended powers in the planning and implementation of regulatory measures.
JIROUŠEK, Jan
The title of this thesis is Situation of Municipalities with Extended Competence in Planning and Implementing Regulatory Measures. The objective was to determine whether and how the municipalities with extended competence in the South Bohemian and Vysočina regions are ready to execute regulatory measures and if the level of regulatory measures corresponds with the needs of citizens to whom the measures are applied. In the theoretical section of this thesis, the municipality with extended competence with its authorities is defined. The regulatory measures, their preparation and implementation are introduced. In the research section two hypotheses were stated. The first was focused on quality and adequate training of the staff of municipalities with extended competence so that to minimize the risks associated with inadequate planning and implementation of regulatory measures. The research has proved that from the perspective of municipalities with extended competence there are considerable uncertainties in the interpretation of the practical implementation of regulatory measures by administrative authorities. Significant differences were found in the documentation focused on regulatory measures. The second hypothesis was focused on shortcomings after the implementation of regulatory measures among the population of the South Bohemian and Vysočina regions, in the sense that it negatively affects the tolerance limits. It has been found that most respondents would tolerate the regulatory measures, but according to the response, the readiness of crisis management workers has been rather inadequate. In this thesis, the method of quantitative research was chosen. The technique of data collection was anonymous questionnaires made up for 32 municipalities with extended competence and 100 residents in the South Bohemian and Vysočina regions and for 50 residents of the South Bohemian region. In municipalities with extended competence all 32 municipaties were addressed, but only 24 questionnaires were returned. In the residents all 100 respondents were addressed the return rate of questionnaires was 100%. The results are shown in graphs and as percentages.
