Optimization of inventory management in Rhiag Group
Konečný, Jan ; Vinš, Marek (advisor) ; Carugati, Giovanni (referee)
The thesis deals with inventory management in Rhiag Group. It is particularly focused on enhancement of model which is used for relocation of goods within the group. Purpose of this model is to improve allocation efficiency measured by items write-off value. Initially, author describes making of database which enables quantifying benefits of relocation, followed by testing of optimal relocation algorithm settings and determinig maximal delivery values for each relocation flow. In conclusion, optimal parameters of the model are recommended and benefits for Rhiag Group are estimated.

Process management in a network of medical facilities
Chládek, Jan ; Plášková, Alena (advisor) ; Konečný, Jan (referee)
The goal of this work is to define the basic processes that are necessary for the proper management of dental surgery. Based on this, then built the foundation for the management of dental practices across the network offices. The theoretical part describes all the way which I later took into account the practical part. Attention is also paid to strategic management tools such as the SWOT and PEST analysis. In the practical part focuses on the core processes that affect the proper operation of a well-established practice. Together with a selected physician practices we have defined and tried to straighten some processes. As a part of this Master's thesis, there are some own ideas how to improve the process in dentistry office. There are also defined the processes for network of medical facilities.

Measurement of urine absorbance with indicator Mn2+
KONEČNÝ, Jan
Measurement of urine absorbance which has been irradiate by a dose of ionising radiation with addition of Mn2+ should serve to find the dose of radiation. This method could work quickly and reliably for homogeneous irradiation of person or as a rough estimate of the dose which the person received during a radiation accident. This method should serve for quick classification of the person. The target of this thesis is to find out if the irradiated urine with the addition of a solution of manganese chloride will change absorbance according to radiation dose. And if urine can be used as a biological dosimeter. In the theoretical part I describe the basic areas related to the topic and target of my thesis. This part is divided to seven subchapters: ionising radiation, radiation protection, radiotherapy, particle accelerators, spectrophotometry, excretion and urine, and dosimetry and its methods. Methods of this thesis are not clear. I tried different procedures during experiments with different results. First, I always prepared samples of urine in tubes and irradiated it in a linear accelerator Clinac 2100C/D in České Budějovice, a.s. hospital with doses from 1 to 25 Gy. Before each measurement I had two sets of tubes with these doses: 0, 1, 2, 3, 5, 7, 10, 15, 20 and 25 Gy. The following procedure was different in each experiment. Sometimes I tried adding a solution of manganese chloride to all tubes at once. Sometimes I tried to adding a solution of manganese chloride to each tube separately. I added the solution to irradiated urine at various concentrations of solution (from 1 do 5 mols) and different amounts (from 1 to 3 ml). Another difference was the use of centrifuges. A centrifuge was use in about half of experiments. Other measurements were made without centrifugation.In discussion I propose recommended methods. I recommend measuring only without centrifuges. Each cell should be measured as soon as possible after irradiation and simultaneously as soon as possible after adding the solution of manganese chloride. Results of the thesis are not clear. Only some experiments which were measuring with centrifuge were clear. I can say that this method does not work when a centrifuge is used at any tested concentration of solution of manganese chloride. The absorbance of single doses of ionising radiation does not change and the values were the same when using 1M, 3M and 5M solutions of MnCl2. The resulting graphs from all experiments have a constant absorbance value of all measured doses. (subchapter 3.1).In the remaining experiments measured without the centrifuge the results were much more interesting. In some experiments the measured absorbance really changed with the dose of ionising radiation so the hypothesis of this study was confirmed. But the differences were too small for this method to be used for measuring radiation doses (subchapter 3.2).The results were compared with the results of the thesis ?Measurement of urine extinction in depending on ionising radiation? from author Š. Radová. She performed a similar experiment, but with a different indicator - FeSO4. 7 H20. It was found that the indicator FeSO4. 7 H20 is preferable to measuring doses of ionising radiation in urine. In conclusion I can say that the hypothesis of this study was confirmed, but the method could not be used in practice and irradiated urine with added MnCl2 indicator does not function as a biological dosimeter.

SOCIAL ROLE OF AN ACTOR IN THE CZECH THEATRE
Konečný, Jan ; Mrkvička, Ladislav (advisor) ; Hlaváčová, Jana (referee)
The present thesis synthesizes my reflections on the role of an actor not only in dramatic arts but in the Czech society as a whole at the turn of the 21th century. It is a reflection of all I have seen, observed and learned. I?m seeking not only to voice my personal opinions, but to put them forward from the wider perspective of Czech society, and as a representative of one generation. The text is therefore subjective and personal.

Marketing applications in dental office
Chládek, Jan ; Koudelka, Jan (advisor) ; Konečný, Jan (referee)
The goal of this Bachelor's Thesis is to apply the tools of marketing mix in the dental environment. In the theoretical part, I described all the bases, which are relevant to the issue. Attention is also paid to analytical methods such as the SWOT method, or target group analysis and competitive environment. In the practical part, I made acquaintance with the concrete dental practice on which I want to show the marketing mix and other instruments mentioned in the theoretical part. Element of this thesis is to propose my own solutions, which could inspire the practice's owner in the future being to be strengthen its overall position for dental service on the local market.

Computer processing of tomography data
KONEČNÝ, Jan
Computer processing of tomography data Tomographs are one of the most important diagnostic devices, which are used in every hospital nowadays; they have already been so for a considerable period of time. The different types of tomographs and the processing of tomographic data and imaging of these data are the subject of this thesis. I have described the four most common types of tomography: X-ray Computed Tomography, Magnetic Resonance Imaging, Positron Emission Tomography and Single Photon Emission Computed Tomography. This thesis has described the basic principles of these devices, their technical parameters, their use and also different data formats, which are used for tomographic data. The practical part of my thesis is involved with software for viewing and processing of tomographic data. It specifically concerns freely available viewers such as MRIcro, ezDICOM, Amide, ImageJ and Gpetview. Their main functions and their pros and cons have also been described therein. The last part of my thesis has been devoted to SPM software that is used for an advanced processing of 3D tomographic data from PET, VBM and MRI as well as EEG and MEG imaging techniques. I have described these features and also those individual steps that are taken during the processing of particular sample data that has been taken from examinations on functional Magnetic Resonance Imaging. This thesis is addressed to all, those who want to learn more about tomographic data processing and mainly it should serve as an overview of free software for processing and viewing of these data.
