The aim of the thesis is evaluating of methods used for assessing damages made by the game on a natural wood restoration in a forestry office in Buchlovice. For assessing damages, data of checking and comparing areas, biting areas with the use of fencings, transects and artifically established cultures. Single methods were evaluated separately and the amount of damages, according to the methods and evaluating of plants, were compared next. The data of 7 checking and comparing areas, 10 biting areas, 11 transects and 10 cultures were used for the evaluation. Three most represented plants were evaluated.

The thesis proposes a structural solution to the folding bed, which is combined with a workspace that even after folding of the bed itself remains in the horizontal position, and therefore it is not necessary to clear away objects lying on it. The proposed design is based on theoretical knowledge of the subject, which are collected and shown in the first part of the text. The solution is therefore supported by both technical and safety requirements as well as requirements for anthropometry and ergonomics, especially of beds, but also of desks. The structural design is drawn up using form of manufacturing drawings including bill of materials, economic evaluation of the level of direct material costs, and created visualizations. At the same time it is based on gathered informations by research of Czech market in supply area of folding beds which was evaluated in terms of price, design, and materials used in the manufacturing process.

The main objective of this thesis is the analysis and comprehensive review of agricultural tires designed for agricultural tractors highest performance class. Another part deals with the description and evaluation of major parameters for calculating the contact surfaces of tires with respect to an individual combination of inflation pressures and loads. The first part was prepared by literature review. Followed by laboratory testing focused mainly on determining the tire contact area with respect to an individual combination of inflation pressures and loads. The first part of the testing procedure was aimed at verifying the functionality and accuracy of the Plantograf. The second part of the test procedure included the estimate of the relationship between the wheel load and pressure distribution in the contact area of the tread of the tire under static loading. The last part of the test procedure consists in comparison of static and dynamic load tires. The measured and calculated values were processed into the relevant tables and graphs.
