This master thesis deals with the application of various types of surface treatments on selected tropical wood species and the subsequent change of colour due to the effect of natural and simulated UV radiation. Measurements were performed on the following three species: zebrano (Microberlinia brazzavillensis), panga panga (Millettia Stuhlmannii) and african padouk (Pterocarpus soyauxii). As surface treatment were used water-based, polyurethane, oil and solvent-based paint. Samples were exposed to simulated UV radiation. The total duration of radiation was 168 hours. After that the colour changes delta E* were measured by using a spectrophotometer. The aim was to compare the different paints used on all woods and their colour change. The thesis also includes research of light permanency of coating exposed to natural UV radiation.

This thesis focuses ontopic regarding: „Tropical pavilions in zoological gardens as living space for nontargeted species (spiders) – complex study” is focused on generic diversity of original and non–native species (mostly spiders) in tropical and subtropical pavilions of zoological gardens in Brno and Prague. The final goal of this thesis is to gather information in local pavilions and terrariums and determinating generic diversity especially in non–native species of spiders. Collecting samples was done by land–falling traps and on a few occasions by hand. Collected samples of invertebrates species were then determinated. Main goal was to determinate, which local rare species of local and mostly non–native species occur in zoological gardens. After the determination was done the most occured species were Parasteatoda tepidariorum (Koch, 1841) in Brno ZOO and Hasarius adansoni (Audouin, 1826) in Prague ZOO. The most interesting findings were Heteroonops spinimanus (Simon, 1892), Theotima minutissima (Petrunkevitch, 1929) a Prodidomidae Simon family, 1884, which occurence were in Czech Republic not yet recorded. Furthermore were found few species which are in Czech Republic rare, primarily Nesticodes rufipes (Lucas, 1846).

The name of the thesis: Practical exercises using the theme of tropical and subtropical fruits in teaching natural history and biology describe the basic issue that the following text is devoted to. This thesis is connected to my bachelor thesis, "Tropical Fruit in Natural History and Biology Textbooks," defended in 2010. The main objectives of the thesis was to complete the contentual analysis of natural history and biology textbooks for the 2nd degree of primary schools, lower grades of grammar schools, and secondary schools. I focused on the issue of the incorrect inclusion of certain plants in chapters for tropical and subtropical fruits. Based on the total contentual analysis of textbooks, I have chosen the processing of practical exercises with the theme of tropical and subtropical fruits as the main objective. Based on the evaluation of the questionnaire, which served as a basis for practical exercises, in which teachers of natural history and biology were addressed, I was focused primarily on lab exercises, worsheets, proposals for project days, didactic games, and excursion worksheets, when creating the practical exercises. The subsequent objective was to verify one laboratory exercise in teaching. The result of this thesis is not only a brief review of natural history and biology...

The diploma thesis deals with the light permanency changes of some chosen tropical woods. Their trade names are garapa (Apuleia Leiocarpau), angelim (Hymenolobium Petraeum), meranti (Shorea spp), sapeli (Entandrophragma cylindricum), merbau (Intsia bijuga), massaranduba (Manikara), teak (Tectona grandis), iroko (Chlorophora excelsa) and eucalyptus (Eucalyptus grandis). The woods are surface modified by means of four different surface modifications both with and without a usage of an alcohol base. All samples were lighted up by artificial sunlight from the xenon lamp for 106 hours by lighting 209,7 KJ/m2. The colour changes were measured during the exposition according to the greyscale and spectrophotometer in the CIEL *a*b* color model. Then the individual woods' color changes depending on the surface modification were assessed by the color difference deltaE*.

The thesis focuses on analyses of relations between risk factors and dengue fever incidence in a selected area of Southeast Asia region. Specifically, it focuses on the Philippines, where the governmental organizations provide relatively sufficient amount of data. First, general problematic of Neglected Tropical Diseases with focus on dengue fever is introduced. Its transmission and influencing factors are specified. Then, current methods of dengue incidence and risk factors relationship modelling are reviewed. Furthermore, statistical processing of available data is carried out, especially, in terms of detailed analysis of the relationship between climatic factors and dengue incidence in the Philippines. Based on the obtained results, a mathematical model describing the relationship between dengue, cumulative precipitation and mean temperature on regional and weekly basis, is created. Model estimation is performed with generalized linear regression by applying negative binomial distribution. With the model, the dengue incidence dependency on selected risk factors was verified. Concurrently, overall complexity of the disease development and transmission was verified by the model.
