Syndrom vyhoření a jeho dopad na pracovníky pomáhajících profesí v církvi / Burn-out syndrom and its impact on workers of helping profession in the Church

Kamarýtová, Anna January 2014 (has links)
This diploma thesis deals with the topic of burnout syndrome and its impact on Church related community workers, in order to determine how much are these workers endangered, how to take care of these workers and whether their employers are familiar with the risks of burnout syndrome. The first chapters are devoted to the theoretical definition of burnout syndrome in the overall view on this issue, but also takes a closer look on Church related community workers in the helping profession in the Church. I'm trying to capture a fully describe the motivation for helping, factors leading to burnout syndrome, diagnosis, prevention and treatment. The final chapter and the whole practical part is devoted to the history and characteristics of the studied groups, which form the priests of the three largest churches in our country: Roman Catholic, Evangelical and Czechoslovak Hussite Church. This part is a quantitative research. To illustrate the work I decided to include three case studies that document the real life stories of burnout syndrome at different stages.

Počítačová simulace kolapsu budovy zplastizováním kloubů / Computer simulation of building collapse due to formation of plastic hinges

Valeš, Jan January 2012 (has links)
The aim of the thesis is to create an analytical 2D model of a multi-storey building and its consequent loading until the point of collapse which occures due to formation of plastic hinges. The first part is going to present a linear analysis of the problem; it focuses on location and level of load when the plastic hinges are formed. Then a nonlinaer analysis is going to be performed by RFEM programme using postcritical analysis and dynamic relaxation. Differences between the results of mentioned types and methods of analysis are going to be compared and an impact of variables is going to be evaluated .

Aquapark Brno / Water park Brno

Brázdová, Zuzana January 2018 (has links)
The subject matter of the assigned project is Aquapark Brno – located near Lužánky. The subject is an architectural study elaboration of an aquapark adjoining the current swimming pool building which was established in 1979. This building facility is used primarily by professional swimmers and sportsmen for it contains the only 50 meters long swimming pool with a tribune in Brno. The aim of the project is to create new areas and pools for visitors with recreational intentions and therefore to widen the possibilities for free time activities. The project also deals with restoration of a 16 meters long training pool in the existing building, creation of inner and outer aquapark areas and adding exercise and dance halls as an extension to the existing fitness center. Another goal of this project was to make the pedestrian access to the area more pleasant which is achieved by creating an underground parking space in the area of the existing building’s frontal space and also by designing a footpath leading from the remote side of the excessively frequented Sportovní street. The primary aim of the project is an operational connection of the existing and the new building by a central building and also preventing an eclipse of the area by integrating the building in the area’s hillside. The advantage of the project is the presence of relaxation facilities and sports areas. The project completes the sporting environment of the area which makes it an attractive locality for a family recreation.

Interakce hyaluronanu s hydrofobními soluty / Hyaluronane interactions with hydrophobic solutes

Slezáková, Dagmar January 2008 (has links)
The diploma thesis is based on the study of hydrophobic interactions of the native hyaluronan with selected solutes. On the basis of a literature search were chosen fluorescent probes and fluorescing biologically active substances, which are useful for investigation of colloids as 6-(p-toluidino)-2-naphthalenesulfonic acid (polarity probe), lipophilic vitamin (±)-alpha-tocopherol, pyrene (polarity probe) and finally hydrophilic vitamin riboflavin. In the experimental part of this thesis was studied the influence of solvents with different polarities, or more precisely dielectric constant, on the emission spectra, as well. There were investigated interactions of native hyaluronan with TNS and then interactions, which were influenced by the ionic strength. Such influenced interactions were not observed, that was probably due to the strong solvation´s wrapping of the hyaluronan. Interactions were observed after the process of lyophilisation followed-up by the rehydratation of the samples. For the next study of interactions the riboflavin was chosen and was investigated the REES effect in the native hyaluronan in different concentrations of its different molecular weights. In this case were not observed any shifts in the emission maximum with the excitation wavelenght shift and that is why the interactions of hyaluronan with riboflavin were not demonstrated in the field of chosen concentrations. By using another probe alpha-tocopherol was investigated the associative behaviour of hyaluronan and moreover was observed anisotropy of alpha-tocopherol in different concentrations of different molecular weights of native hyaluronan. The anisotropy reached high values in contrast to the reference solute that was the mixture of glycerol and ethanol. The anisotropy depended more on the molecular weight than on the concentration of hyaluronan. Interactions of hyaluronan were also studied by using the polarity probe pyrene in different concentrations of different molecular weights of the hyaluronan. The pyrene 1:3 ratio did not show the concentration dependence within the chosen concentrations except for the molecular weight 253.9 kg mol–1. Both probes alpha-tocopherol and pyrene were performed by the process of lyophilisation followed-up by the rehydratation, which improved interactions of these probes with hyaluronan.

Bravenec, Ladislav January 2013 (has links)
The aim of the thesis is to compare the iterative methods which program RFEM 5 uses the non-linear calculations of structures, namely the analysis of large deformations and post critical analysis. Comparison should serve as a basis for which calculation method is the most accurate, fastest and most reliable in terms of getting results. Time-consuming will be judged according to the calculation of the solution and the time needed to compute one iterativ. Robustness we will compare the reliability of methods in in normal use. Accuracy of the calculation will be determined by comparing the maximum deformation structures. Comparison will be made with examples from practice.
