Šťastný, Pavel ; Houška, Milan (advisor) ; Hlavatý, Robert (referee)
The aim of this thesis is, by using the methods of multi-criteria decision, to design and recommend a suitable variant of the communication for the pedestrian for the preparation of a tender documentation for the public tender in the village of Dolany.
The issue of the decision-making processes in the selection of the optimal variants using the methods of multi-criterial decision-making is analyzed in the literature research of the publication. The description of multi-criteria methods reflects the subsequent procedure of the calculation in the practical part. Research also deals, regarding to the theme of the publication, with selected requirements in the procurement, sub-targets of the tender documentation for the selection procedure and a brief specification of the communication for the pedestrian.
The practical part of the thesis starts with the description of the village of Dolany and the preparation for the setting the options. The determination of the possible variants and the choice of different criteria follow. The selection of the compromise variants is carried out using the method of the analytical hierarchical process (AHP) for the possibility of inclusion also qualitative criteria which cannot be fitted into the framework of the tender documentation. In the end, the selected option is recommended to the village of Dolany.

Cereals - Active Substances, Biological Effects and Selected Applications in Food Industry
Lichnová, Andrea ; Tremlová, Bohuslava (referee) ; Vávrová, Milada (referee) ; Márová, Ivana (advisor)
The presented doctoral thesis is focused on the study of the biological effects of active compounds found in cereals, on the development of methods of analysis these effects, on the determination of the content of active substances and characterization of the relationship between composition and biological effects of cereals and cereal products. For the analysis several kinds of raw cereal samples (flakes, flour, germ, bran), flavored extruded cereal products and also samples of paddy and husked rice were chosen. To major types of analysed active compounds belong mainly phenolic compounds in the form of glycosides and aglycones, and also saccharides. Group parameters such as total polyphenols, flavonoids and total and reducing saccharides were determined spectrophotometrically, individual phenolics and saccharides were determined by high performance liquid chromatography (HPLC). TEAC, DPPH and CLAMS methods were used to determine the antioxidant activity. Indirect methods of determination of substances with antioxidant effect were used as well. Results of the total antioxidant activity were compared with values of antimutagenic/genotoxic activity obtained by several microbial test systems. Antimutagenic effect was expressed as a percentage of inhibition of effect of standard mutagen and could be considered as a potential preventive effect of cereals to DNA arising primarily by free radicals effect. The highest values of group and individual phenolics, antioxidant and antimutagenic activity were found in germs, bran, in buckwheat products and in coloured and raw rice. In flavoured cereal products addition of chocolate or fruit positively influences content of active phenolic substances as well as sugars, antixidant and antimutagenic activity. In a representative sample of Czech population, questionnairy study was performed to monitor interest in cereals and consumer preferences. The most of consumers consider cereals with chocolate flavour as less healthy than confirmed results of laboratory analyses. In this study some new food products were developed. Several types of model cereal products containing plant (fruit, vegetables) extracts were proposed. Extracts were added to cereals in freeze-dried and encapsulated form. The highest positive effect exhibited addition of local forrest fruit extract. Within preparation of encapsulated extracts several methods of preparing lipid or saccharides particles were also tested. The encapsulation efficiency of the methods and stability and size of particles were analysed. Optimal type of fortified cereal foods could be suggested based on the acquired results. Selected cereals were used as alternative carbon substrates (processed or raw) for the cultivation of microorganisms to produce enriched biomass usable in the feed industry. We can conclude that cereals in raw as well as processed form belong to universal foods and rich sources of biologically active substances. They can be processed by many ways. They can be used for direct consumption, as a part of new products and also undirectly as a substrate for feedstock.

The evaluation of coefficients when determining the optimal number of clusters in cluster analysis
Novák, Miroslav ; Löster, Tomáš (advisor) ; Makhalova, Elena (referee)
The objective of this thesis is the evaluation of selected coefficients of the cluster analysis when determining the optimal number of clusters. The analytical evaluation is performed on 20 independent real datasets. The analysis is made in statistical SYSTAT 13.1 Software. The application of coefficients RMSSTD, CHF, PTS, DB and Dunn's index on real datasets is the main part of this thesis, because the issue of evaluating the results of clustering is not devoted sufficient attention in scientific publications. The main goal is whether the selected coefficients of clustering can be applied in the real situations. The second goal is to compare selected clustering methods and their corresponding metrics when determining the optimal number of clusters. In conclusion, it is found that the optimal number of clusters determined by the coefficients mentioned above cannot be considered to be correct since, after application to the real data, none of the selected coefficients overcome the success rate of 40%, hence, the use of these coefficients in practice is very limited. Based on the practical analysis, the best method in identifying the known number of clusters is the average linkage in connection with the Euclidean distance, while the worst is the Ward's method in connection with the Euclidean distance.

Productivity dynamics of herb layer in the thermophilous oakwood in the Nature Reservation Na Voskopě (Czech Karst) with respect to the solar radiation intensity
Mevald, Ondřej ; Černý, Tomáš (advisor) ; Josef, Josef (referee)
The Nature Reserve Na Voskopě is a special site where a long-term experiment was established in 2013, dealing with the switch of a long abandoned coppice back to its actively managed form. The project aims to examine the long-term impact of the proposed measures on the structure and diversity of plant species in herb layer especially in lighter woods at lower altitudes. The specific aim of this study was to examine the hypothesized crucial role of light conditions on the dynamics of plant biomass production in the undergrowth of such experimentally opened up thermophilous oak-dominated stand. A design was set up based on 40 permanent plots, where there were taken biomass samples from the herb layer in 2015. Further on, hemispherical images of forest canopy were photographed in the centre of each permanent plot. These images were evaluated in the analytical program WinScanopy, which calculates the amount of direct and diffuse radiation. The obtained datasets were evaluated by the regression analysis. The only decisive variable affecting the productivity of the herb layer turned to be diffuse radiation. The biomass data were also compared with light conditions sampled in the previous season (2014) as a part of ongoing experimental research. Season 2014 is characterized as a normal one and we managed to find a much stronger relationship between light conditions in 2014 and biomass productivity in 2015. Light conditions in season 2015 were significantly affected by the extremely dry and hot weather leading to strong defoliation of forest canopy. Still, we managed to demonstrate the positive impact of light conditions for the production of herb layer biomass. Weather extremes may also indicate an increase in biomass production in the next season, since a significant proportion of nutrients remained unused in the soil due to stopping the growth of vegetation. The current composition of the vegetation is very often determined by the extreme events in the abiotic environment occurring not long ago. Hemispherical images also proved as a very effective way to determine the light conditions, so it is also recommended to use for further research.

The effect of water stress on the content of monosaccharides in potato tubers
Podhorecká, Klára ; Orsák, Matyáš (advisor) ; Hnilička, František (referee)
Bachelor thesis is focused on monitoring of influence on selected metabolites, especially monosaccharides. The first part is devoted to short characterization of potatoes, therefore the importance of this crop, morphology, cultivation and also are described demands of potatoes on environment and nutrition.
In the next section is detailed discussed problems of the chemical composition of tubers with a focusing on carbohydrates. Potatoes are globally consumed and are popular source of carbohydrates. Potatoes are rich in vitamins also, especially in vitamin C, B3 and B6. Potatoes contain a high content of minerals, especially potassium and magnesium, too. As another substances are in potatoes colorants, antioxidants, phenolic and related substances, proteins, and small amount of lipids. It is noted that proteins of the potato tuber are ranked among nutritionally valuable proteins of vegetable origin. Among this proteins is ranked Patatin, which is considered to be a major reserve protein and it is placed in the vacuoles. Substances, which has a negative effect on the human body are called Glycoalkaloids the opposite. Glykoalkaloids are synthesized by plants of the family Solanaceae. The most significant substances in potatoes are alfa-solanine and alfa-chaconine. Value of tubers is primarily determined by their chemical composition, which forms food and raw materials. The contents of sugars in the tubers are relatively low (0,5 % of the original mass), and even though their contents are important both in aspect of manufacturing and in sensory aspect. The main reducing monosaccharides are ranked glucose and fructose, typically with a concentration of 0,15 - 1,5 %. The sugar content significantly affects internal and external quality characteristics especially fried products. Several studies confirm that the accumulation of carbohydrates might help resist extreme stress conditions, especially low temperatures, salinity and water deficiency.
In the next chapter is created summary of stress conditions effects on plants with focusing on potatoes. In plants we can talk about stress, if variability of negative environmental factors exceeds a certain limit. The main theme and also the most limiting factor is deficiency of water in other words water stress. Also were mentioned other factors abiotic and biotic factors marginally.
By effects of stress reaction is created a specific level of adaptive skills. Temporarily it can lead to acclimatization, which increasing the resistance to abiotic stressors. Most of plants are trying to establish the tolerance to stress. In this Chapter were also described changes during storage and during heat treatments of potato, which leads to an undesirable darkening of the tubers. Excessive levels of reducing sugars cause unacceptable browning of fried products.
In the last chapter is described selected methods of determining carbohydrates. These methods are based on reducing properties of sugars, on their condensing reactions by color, measurement of optical activity, measurement of refractive index, separation methods and others.
The methodic of work clarifies the determination of reducing monosaccharides (glucose, fructose), sucrose by the high performance liquid chromatography (HPLC) in four selected varieties of potatoes from harvest of 2015.
