Havránková, Lucie ; Vrzal, Tomáš (advisor) ; Olšovská, Jana (referee)
In this work, reactions of selected beer components (especially amino acids and phenolic compounds) with nitrite ions in an acidic environment and analysis of the resulting reaction products were performed using gas chromatography with mass spectrometric detection. Analysis of reaction products revealed 127 products containing one or more nitrogen atoms derived from nitrite in the molecule. Most of the products were found in ferulic acid, coumaric acid, 5-ethyl-3-hydroxy-4-methyl-2(5H)-furanone and 2-methoxy-4-vinylphenol, no products were found in the case of isoleucine, glutamic acid, phenylethanol and maltol.

Importance of environmental elements (water environment and greenery) in urbanized areas of the Czech Republic
HAVRÁNKOVÁ, Lucie
The aim of the dissertation is to provide an analytical comparison of the effectiveness of using of the environmental potential of watercourses and greenery in urbanized areas/cities of the Czech Republic (ČR). The work is divided into a part of physical-geographical and sociological assessment and research. The physical-geographical analysis will provide the results of watercourse use in the city using the Urban River Sustainability Index (URSI) and watercourse availability analysis. In the area of eva-luation of cities in terms of greenery, the results are obtained through the calculation of the Indicator of the General Quality of Greenery in Cities (IOKZM) based on the Coefficient of Ecological Stability (KES) and the evaluation of the share of greenery in cities. Sociological research provides the user's opinion on the positive environmental contribution of the watercourse in specific urbanized areas, based on the results of quantitative and qualitative research. This section is statistically evaluated using logistic regression (LR) and multivariate correspondence analysis (CA). The overall results of the work create an overal image of the importance of environmental elements (water environment and greenery) in urbanized areas of the Czech Republic. They draw attention to the current state of Czech cities and suggest possible improving solutions not only for their changing climatic situation.

Poetics and picturesque in a landscape
Havránková, Lucie ; Hnízdil, Aleš (advisor) ; Jiří, Jiří (referee)
The subject of the thesis is a description and depiction of poetics and picturesqueness of landscape using the elements of East Asian landscape poetry as a source of inspiration to perceive the beauty of the landscape surrounding the South Bohemian village of Kvilda. Based on the study of landscape poetry texts, a specific mountain trail was chosen to capture this poetics and picturesqueness. By choosing well-selected stopovers on this trail, the thesis is aimed to evoke the perception of poetic elements of nature in the overall context of the surrounding countryside. Here, the text description of the esthetic values of landscape and environment is the way to create a project of revitalized landscape with picturesque features and specific vegetation species.
This work is also explained in the context of Šumava, which is described in the introductory part of the thesis so that the reader will gain a better understanding of the project setting. This introduction acquaints us with the natural and artistic background of Šumava and the environs of the village of Kvilda that surround the trail.
The whole project comprises the analysis of the environment of each stopping place on the trail, the description of its main points of interest and the transformation of the place in different seasons of the year in respect of a particular landscape feature. Each stopover is supplemented with landscape poetry texts with the aim to capture the atmosphere of the place even better. At the end of each chapter associated with a particular stopping place there are art displays which are specific to this environment. These should acquaint the visitors with the environment and offer them an inspiration that each place conceals. The whole project imitates a tour through nature and draws attention to individual points of interest in the landscape, which we so often tend to overlook. The above aspects can also be applied to garden and landscape design.
