Hydrides of uranium intermetallics
Mašková, Silvie ; Havela, Ladislav (advisor)
We have been studying variations of magnetic properties as a function of hydrogen concentration for large families of UTX compounds, which prove that doping of U intermetallics by interstitial hydrogen leads to stronger magnetic properties. On the other hand, any dilution of uranium sublattice by a non-magnetic element leads to the suppression of magnetism. This was demonstrated e.g. on the case of U1-xThxCoSn, in which the long-range ferromagnetism vanishes at approx. 60% Th, preserving the same hexagonal structure (ZrNiAl type, space group P62m ) through the whole concentration range. It is intriguing to investigate whether the interaction with H is changed when replacing Th for U, and whether magnetic properties are affected by the H doping in the analogous way as in pure UCoSn, in which it leads to the increase of TC from 82 K to 102 K for UCoSnH1.4. Here we report on the changes of crystal structure and magnetic properties due to hydrogenation of U1-xThxCoSn (x = 0.2, 0.4, 0.6, 0.8, 1).

Analýza finančních toků spojených se zdravotnictvím a spokojenost pacientů se zdravotní péčí poskytovanou v soukromě vlastněných nemocnicích v České republice
Supová, Aneta ; Štěrbová, Ludmila (advisor)
This Master Thesis focuses on the structure of health related financial flows and patient satisfaction with privately owned hospitals in the Czech Republic. The main aim was to provide a general overview of health care system in the Czech Republic, to describe how the health care system is financed, and to find out if patients hospitalized in privately owned hospitals are more satisfied with the care provided in this type of hospitals. Having analyzed the major statistical reports from the WHO, EU, and the Institution of Health Information and Statistics of the Czech Republic, the theoretical part provided a comprehensive summary of health care, health financial flows, and pricing of health treatments. The practical part, on the other hand, shows distribution of health costs among differently aged people in the form of contribution/expenditure ratio. Finally, the results of the questionnaires conducted among patients in privately owned hospitals enabled to conclude that patients in the Czech Republic are still not fully aware of the difference between privately and publically owned hospitals.

Generalization of the methodology for evaluation of the gear windage loss
Bauer, Petr ; Kordík, Jozef ; Krátký, Tomáš ; Sedlář, Milan
The first part of the report proposes a methodology for gear windage loss evaluation using CFD analysis. The methodology includes simplification of gearbox complex geometry and the toothed wheel and pinion are replaced by a rough-walled disks with additional braking volume forces. The values of volume forces were determined using auxiliary computations with a real gear geometry (a gear segment with periodical boundary conditions). The computations included configuration of the gear wheel meshing with the pinion, while distance of wheel enclosure was a variable parameter (the case without enclosure was tested as well). The cases without pinion were computed too, they were compared with earlier results obtained with the gear segment geometry.\nThe second part of the report contains a revision of the earlier proposed analytical approach. The approach can serve for approximate gear windage loss evaluation and its idea dwells in smooth connection of logarithmic velocity profiles. The gear windage loss values obtained from the analytical approach were compared with the results based on CFD analysis. A good agreement between both methods was concluded.\n

The language of medical reports and its information-lexical analysis
Přečková, Petra ; Zvárová, Jana (advisor) ; Hanzlíček, Petr (referee) ; Skalská, Hana (referee)
The objective of the dissertation thesis has been the information-lexical analysis of Czech medical reports and the usability of international classification systems in the Czech healthcare environment. The analysis of medical reports has been based on the attributes of the Minimal Data Model for Cardiology (MDMC). Narrative medical reports and structured medical reports from the ADAMEK software application have been used. For the thesis SNOMED CT and ICD-10 classification systems have been used. There has been compared how well attributes of MDMC are recorded in narrative and structured medical reports. The language analysis of the Czech narrative medical reports has been made. A new application for measuring diversity in medical reports written in any language is proposed. The application is based on the general concepts of diversities derived from f-diversity, relative f- diversity, self f-diversity and marginal f-diversity. The thesis has come to the conclusion that using a free text in medical reports is not consistent and not standardized. The standardized terminology would bring benefits to physicians, patients, administrators, software developers and payers and it would help healthcare providers as it could provide complete and easily accessible information that belongs to the process of...

Regulation of Cathepsin D Activity and Activation
Máša, Martin ; Mareš, Michael (advisor) ; Jonáková, Věra (referee) ; Holada, Karel (referee)
PhD Thesis ABSTRACT REGULATION OF CATHEPSIN D ACTIVITY AND ACTIVATION Martin Máša supervisor: Michael Mareš Department of Biochemistry Faculty of Science Charles University Institute of Organic Chemistry and Biochemistry Academy of Sciences of the Czech Republic PRAGUE 2009 Introduction Cathepsin D (CD) is an aspartic peptidase located in the lysosomes of all mammalian cells, its main role is catabolic degradation of proteins. More over CD is known to participate in a range of physiological processes such as apoptosis and tissue homeostasis, as well as in the regulation of angiogenesis and the production of peptidic antigens. The role of CD in pathophysiology is associated with several diseases such as Alzheimer's disease and cancer. Alzheimer's disease is a neurodegenerative disorder, which is generally considered to be the most common form of dementia. Progression of this disease is accompanied with the deposition of amyloid plaques (AP) in the brain, which leads to neurodegeneration. The AP is a fragment released from amyloid precursor protein (APP) cleaved by secretases1 . High levels of CD were found in cerebrospinal fluid of the Alzheimer's patients2 . It was demonstrated that CD is able to cleave APP and produce the pathogenic AP. A genetic polymorphism in the CD gene was reported, which changes...

Competing on Analytics
Nagin, Gleb ; Pour, Jan (advisor) ; Basl, Josef (referee)
Business analytics refers to the skills, technologies, applications and practisies for continuous iterative exploration and investigation of past business performance to gain insight and drive business planning. Business analytics focuses on developing new insights and understanding of business performance based on data and statistical methods. Business intelligence traditionally focuses on using a consistent set of metrics to both measure past performance and guide business planning, which is also based on data and statistical methods. Analytics makes extensive use of data, statistical or quantitative analyses, explanatory and predictive modeling, and fact based management to drive decision, making. Analytics may be used as input for human decisions or may drive fully automated decisions. In other words, querying, reporting, OLAP, and alert tools can answer questions such as what happened, how many, how often, where the problem is, and what actions are needed. Business analytics can answer questions like why is this happening, what if these trends continue, what will happen next, what is the best that can happen (optimize). Example of application analytics in different areas: banks use data analyses to differentiate among customers based on credit risk, usage of other characteristics with appropriate product offering. Harrah's company (from 2010 renamed and called Caesers entertaiment. Gaming corporation that owns and operate over 50 casinos, hotels, and seven golf courses under several brands), uses analytics for customer loyalty programs. Deere & Company (manufacturer of agricultural machinery like tractors, combine harvesters, sprayers and other) saved more than $1 billion by employing and implementing a new analytical tool to better optimize inventory. We can mention areas where within analytics are basic domain model: sales/retail business, financial services, risk & credit, marketing, fraud, pricing, telecommunications, supply chain, transportation and many others.

The use of taping and kinesiotaping in physiotherapy
Ševečková, Tereza ; Polavková, Radka (advisor) ; Brožová, Kamila (referee)
This thesis is focused on the possibilities of using taping and kinesiotaping at physiotherapy. Application of the methods was provided in three different diagnoses. These were instability of the knee joint after plastic operation LCA, hallux valgus and backpain in the third trimester of pregnancy. The thesis is divided into the theoretical and practical part. The theoretical part describes the methods taping and kinesiotaping and it refers to the problems of the individual diagnoses. The practical part uses the qualitative research where three case reports are processed. The case reports contain introductory kinesiological analysis, progress of the therapy, checking kinesiological analysis and the therapy's evaluation. In the thesis taping and kinesiotaping are used individually despite the fact that these methods are just supplementary to the therapy. It is done in this way so as to be possible to evaluate the efficiency of these methods in selected diagnoses. Key words: taping, kinesiotaping, plastic operation LCA, knee joint after plastic operation LCA, hallux valgus, backpain, pregnancy
