Temporary strengthening of road bridges
Suza, Dominik ; Kaplan,, Věroslav (referee) ; Pukl,, Radomír (referee) ; Klusáček, Ladislav (advisor)
Bridge strengthening is frequently associated with costly, long-term reconstruction. In some cases the bridge load capacity is sufficient for standard traffic, but requirements for an extremely heavy vehicle can exceed the maximal bridge load capacity. These vehicles normally weigh hundreds of tons. Moreover, well-known bridge strengthening technologies are not efficient and economical for this special load case. This doctoral thesis presents a short-term bridge strengthening method using a temporary support structure for the assistance of the existing bridge carrying structure. Although this strengthening method is rather old, it is rarely known. Approaches from 1980, are still often used, rely on simplified principles and approximation models. This approximation causes restricted efficiency of the strengthening system and creates a mathematical model that is not necessarily safe. The introduced new short-term bridge strengthening theory is based on monitoring of real bridge structures and temporary support structures during the crossing of extremely heavy vehicles. A mathematical model, which represents behaviour of real structures suitable, is introduced. The major effects, which have the greatest influence on this strengthening method are discussed. Further more a safety hydraulic element invented at Brno University of Technology, which can be used with the strengthening system is shown. The application of this system ensures required boundary conditions and therefore it guarantees the proper usage of the strengthening system.

Supporting children in Drawing as a game
Haberhauerová, Klára ; Klusák, Miroslav (advisor) ; Fulková, Marie (referee)
This thesis is focused on the drawing of preschool children from the perspective of a game. The game that can offer children a functional pleasure already during the game itself. Theoretical starting points offer an insight into contemporary Czech and foreign didactics of an art education, the development of graphomotorics and also the theory of correction of specific learning disorders, concretely dyspraxia and dyspinxia. It focuses on the possible cause of refusing to draw, presents the view on the role of the teacher in planning and active participation in the educational process. The theoretical base is followed by an original empirical research that was lead in one kindergarten. The aim of the research was to introduce the Drawing as a game to children, so that they can have a positive experience from it. In the research we can find not only the diagnostics of children in terms of their ability to enjoy drawing as a game, but also self intervention in children, who had little or no pleasure in playing the game at the beginning. The conclusion contains a list of factors that supported individual interventions in their success.

Social agriculture as an alternative business solution for agriculture
ŠVEC, Zdeněk
This bachelor's thesis introduces social agriculture as an alternative business solution in the whole agricultural sector. This work is not focused just on social agriculture but also on agriculture in general and also on some social terms. It also explains the main meaning in social agriculture, its benefits in social life and for what kind of people it can be beneficial and helpful. It analyzes social agriculture in the Czech Republic and in other European countries.The literal research is divided into three parts. The first part is about agriculture in general and its main functions in agricultural sector. In the second part are described some social terms and the third part which is the longest one is about the social agriculture. The third part also deals with financing of farms or companies that concentrate on social agriculture in each country.
