Residuals of pharmaceuticals in waters
Vašíčková, Petra ; Čáslavský, Josef (referee) ; Vávrová, Milada (advisor)
This bachelor thesis focuses on studying synthetic pharmaceuticals spreading into the aquatic ecosystem. Ketoprofen and diclofenac, non-steroidal analgetics were studied. The aim of this work is to develop both a suitable analytic method for analytes isolation from a given matrix and an optimal technique for identification and determination of analgetics residues in waters. Solid phase extraction (SPE) was employed as the separation method for isolation of given pharmaceuticals and high performance liquid chromatography (HPLC) with diode-array detection was used for their determination. The optimised and validation method was used to model samples of water. Obtained results were evaluated and their interpretation was done.

Determination of drug residuals using separation methods
Vašíčková, Petra ; Opatřilová, Radka (referee) ; Vávrová, Milada (advisor)
Nonsteroidal anti-inflammatory substances became a very frequently used and constantly evolved group of the drugs, particularly in a human medicine. The risk of their penetration into the environment, especially to the water environment, is rising during the recent years. The diploma thesis is focused on a selection of appropriate separation method and optimization of analytical procedure for the identification and determination of the non-steroidal anti-inflammatory drugs in sewage and surface waters. Salicylic acid, ketoprofen, diclofenac and ibuprofen were chosen from the wide range of NSAIDs as the most widespread agents of this drugs group in the medical practice. The method was optimized and elaborated using the model water samples. This method was used for determination of the analytes contained in the real water samples. Waste water samples were taken from the large-scale wastewater treatment plant in Brno-Modřice and surface water samples were taken from the Highlands river Křetínka. Solid phase extraction (SPE) was used for the real samples treatment and preconcentration, the determination was performed using the high performance liquid chromatography with mass spectroscopy method (LC-MS).

Monitoring of Social Networks as Part of Marketing Research of Firm
Vašíčková, Petra ; Kincl, Tomáš (advisor) ; Novák, Michal (referee)
The main purpose of this master thesis is to help companies in their work with social networks. The first chapter is a short introduction into social networks and types of their users. The second chapter helps companies to realize how the social networks are connected to marketing activities and what kind of monitoring possibilities they can take advantage of. Then the thesis is focused on what kind of businesses is monitoring applicable for as well as how to correctly determinate goals and monitoring on social networks. These findings are demonstrated on particular company named Foreigners.cz Pilsen.
