Tea is one of the most popular beverages worldwide. It was demonstrated that the beverage prepared by leaching of leaves of Camellia sinensis in hot water, has a positive effect on human organism in many cases. The substances found in green tea have antioxidant properties and positive effects on the prevention of many diseases. The beneficial effects are attributed mainly due to plant phenols whose antioxidative activity protects the body against free radicals. In this work the content of selected biologically active compounds in extracts of loose green teas was determined using modern bioanalytical methods. The amount of natural antioxidants determined in tea from Japan and China at different preparation temperatures of the tea extract solution were compared.

The dominant trend of the current corporate information systems is undoubtedly a growing emphasis on information and their quality. But quality is not the only crucial factor. No less important is speed and flexibility of information acquisition. Due to a dynamic environment in which today's corporation must survive, even the high-quality information are very quickly getting older, lose their value and reduce the competitive advantage the company which manages them. This thesis deals with the analytical portals, which significantly improve work with information and are used largely in modern enterprises. The work consists of two main parts, theoretical and practical. Theoretical part tries to explain what exactly the term "analytical portal" means and what is the role of analytical portal in reference to the company management procedures and existing information systems. In addition to this introduction, theoretical part also contains instructions on how to evaluate the analytical portals. This guidance includes both the various aspects of which you can evaluate the portal and the proposal of possible way of processing results, so they could be used for an objective comparison of more competing products. The practical part contains a practical example of evaluation of specific product. This evaluation is based on the basis of the use of specific tool for creating analytical portal as the implementation of demonstration example, as well as the use of theoretical background as defined in the previous section. In addition to a general introduction to the problems of analytical portals, work may also serve as a basis for the creation of a specific methodology for evaluating different products on the market.

Phenolic substances are synthesized in plants, where they help in their defense against fungal diseases, are used as a significant source of substances by the human population. Phenolic substances are not a human organism capable of producing themselves and it is therefore necessary to take these health benefits in the diet. Grape vines, berries, are very rich in natural phenolic substances. We divide these natural phenolic substances into two basic groups: flavonoid and non-flavonoid, which, thanks to the technology of grapevine processing, pass into wine. Thanks to different grape processing technology, red wine is richer in phenolic content, but the content of these antioxidant components is not negligible even in white wines. Grape vines and their wine products are constantly being studied for the content of antioxidant components and their importance for human health, thanks to the development of modern analytical methods. The results of scientific studies are constantly updated and accepted not only by human health experts but also by the general public.

The work succeeded in defining and arranging the basic typology of approaches to coaching, describing their theoretical starting points, pros and cons in application in the environment of Czech firms. The typology serves the ordering persons (mostly human resources officers) for convenience when looking for an appropriate approach and when choosing an eligible coach. The work defined a new term - analytic coaching - and have provided its specificities and differences from other theoretical approaches, as well as eight case studies where we have proved the efficiency of analytic coaching. The managers being coached within the monitored sample familiarized themselves during the study with coaching procedures, methodology and principles, and they start applying and promoting them within their management of people, becoming the upholders of the new firm culture focused on involvement, independence and self-management of employees. Interest was aroused in the managers being coached in self-development, in study of soft management elements and in coaching applications in the intra- and extra-employment spheres.

In the first part of the thesis is processed literature review focused on the composition of fruit, production of fruit wines and their distribution, and diseases and defects of these wines too. The experimental part of thesis is focused on comparing the sensory substances between fruit wines and grape wines. For the experiment using fruit wines from red currants, sweet cherriesa and sour cherries and red wines from varieties Blue Portugal, from white varieties Müller Thurgau and pink varieties of St. Laurent. Case of fruit musts was made basic analysis of substances. For wines was performed sensory analysis by hundred system. Spectrophotometry was determined the total content of flavanols and anthocyanins. Alpha Spectrometers FT-PR has performed a detailed analysis of the substances in wine Top sensory evaluated wine was currant and St. Laurent rosé. The worst evaluated was the cherry wine. The highest values of flavanols reached cherry wine and grape wine Müller Thurgau, the lowest rate was observed in the sweet cherry wines. The highest measured value of anthocyanins was at sour cherry wine, the lowest measured amount was at grape wine Müller Thurgau. In the comprehensive evaluation can be said that among the surveyed wines don't were significant differences.

This diploma thesis explores analytic techniques used to determine the amount of thermolabile proteins in wine making processes. It also includes the comparison of applied analytic techniques. The analysis was preceeded by the study of available sources dealing with thermolabile proteins, methods of assessment and the influence of thermolabile proteins on the colloidal stability of wine. The applied analytic techniques were assessed in the aspect of accuracy and speed. At the end of the thesis there is the list of reference suitable for wine making processes. In the experimental part I compared different analytic techniques used to determine the amount of thermolabile proteins. The measurements took place at the Institute of Viniculture and Viticulture at the Faculty of Horticulture in Lednice, South Moravia. We used turbidimetric measurable methods, such as heat-cold testing with the temperature of 90 °C and 60 °C for different time range. We also did acidic test with sulfosalicylic acid, trichloroacetic acid, and also taninn and ethanol test. The later testing involved just turbidimetric unmeasurable technique, in the form of a foam test.

This could also create conditions for implementation of new methods.

This diploma thesis is about graph databases, which belong to the category of database systems known as NoSQL databases, but graph databases are beyond NoSQL databases. Graph databases are useful in many cases thanks to native storing of interconnections between data, which brings advantageous properties in comparison with traditional relational database system, especially in querying. The main goal of the thesis is: to describe principles, properties and advantages of graph database; to design own convenient graph database use case and to realize the template verifying designed use case. The theoretical part focuses on the description of properties and principles of the graph database which are then compared with relational database approach. Next part dedicates analysis and explanation of the most typical use cases of the graph database including the unsuitable use cases. The last part of thesis contains analysis of own graph database use case in which several principles are defined. The principles can be applied separately. There are crucial analytical operations in the use case. The analytical operations search the causes with their rate of influence on amount or change in the value of the indicator. This part also includes the realization of the template verifying the use case in the graph database. The template consists of the database structure design, the concrete database data and analytical operations. In the end the returned results from graph database are verified by the alternative calculations without using the graph database.
