Proposing the financial performance prediction index for decision support of the hospital management
Hajdíková, Taťána ; Černá, Anna (advisor) ; Lieskovská, Vanda (referee) ; Lazar, Jaromír (referee)
Dissertation thesis deals with the managerial needs in the area of financial health. Managers need a tool to reveal the impending financial failure or to assess the financial quality of the organization. They link their decisions to performance, ability to pay, employee productivity, financial resources and financial risk. In the theoretical part of the thesis it is necessary to explain the non-profit sector and its connection with the hospital environment. It is also necessary to introduce models used both in the Czech Republic and abroad, which share common elements. The basic aim of this thesis is to propose a financial performance prediction index for decision support of the hospital management, the owners of hospitals and insurance companies. To achieve the basic goal, three sub-goals must be accomplished. The first goal is to divide the hospitals into healthy and unhealthy by using the multi-criteria methods. The second goal is, based on an expert approach with the support of statistical methods, the selection of indicators appropriate for the hospital environment and the third goal is to find a suitable method for the determination of weighted representation of individual indicators in the proposed index and to assemble the final form of the new financial index for the hospital environment.

The capacity of the European Union to form a common foreign policy: The approach towards Russia during the crisis in Ukraine
Grycová, Adéla ; Rolenc, Jan Martin (advisor) ; Cibulková, Petra (referee)
The thesis deals with the issues of framing and europeanization of the foreign policy of the European Union in the context of an actorness of the EU. These two theoretical concepts are applied on the case of an approach of the Czech Republic and European Union towards Russian Federation during the crisis in Ukraine. The aim of this thesis is to find out if the European Union is capabble of affecting the behaviour of a member state in order to create unified and operational foreign policy. The first chapter deals with teoretical definition of the two concepts and detailed description of the stances of Czech Republic and European Union follows in the second one. On the basis of these chapters the assessment is conducted. The last part firstly concludes if any attempt of influecing is present and secondly the success rate of the attempt is evaluated.

The role of acetylation in the RNA recognition motif of SRSF5 protein
Icha, Jaroslav ; Staněk, David (advisor) ; Šenigl, Filip (referee)
Acetylation is emerging as an important posttranslational modification, which is found in thousands of proteins in eukaryotes, as well as prokaryotes. Global proteomic studies implicated acetylation in regulation of various processes like metabolism, gene expression, cell cycle or aging to name a few. In this work I set out to investigate the role of acetylation of a splicing regulatory protein SRSF5 by creating mutations in its acetylation site. I tested the hypothesis that acetylation influences SRSF5 interaction with RNA. I expressed acetylation-mimicking (Q) or non-acetylable (R) mutant of SRSF5 in HeLa cells and measured their interaction with RNA by RNA immunoprecipitation or in vitro by fluorescence anisotropy. Both approaches agreed that mutants interact with RNA less than the wild type protein and Q mutant bound RNA weaker than R mutant. I did not detect further difference in localization or dynamics among the proteins in vivo, which suggests that difference caused by weakened interaction of mutants with RNA was outweighed by other factors influencing SRSF5 behaviour, probably protein-protein interactions. I also found out that mutant SRSF5 proteins do not have a dominant effect on splicing of fibronectin alternative EDB exon. The data obtained give an indirect evidence for the hypothesis that...

del Corro, Elena ; Peňa-Alvarez, M. ; Morales-García, A. ; Bouša, Milan ; Řáhová, Jaroslava ; Kavan, Ladislav ; Kalbáč, Martin ; Frank, Otakar
The research on graphene has attracted much attention since its first successful preparation in 2004. It possesses many unique properties, such as an extreme stiffness and strength, high electron mobility, ballistic transport even at room temperature, superior thermal conductivity and many others. The affection for graphene was followed swiftly by a keen interest in other two dimensional materials like transition metal dichalcogenides. As has been predicted and in part proven experimentally, the electronic properties of these materials can be modified by various means. The most common ones include covalent or non-covalent chemistry, electrochemical, gate or atomic doping, or quantum confinement. None of these methods has proven universal enough in terms of the devices' characteristics or scalability. However, another approach is known mechanical strain/stress, but experiments in that direction are scarce, in spite of their high promises.\nThe primary challenge consists in the understanding of the mechanical properties of 2D materials and in the ability to quantify the lattice deformation. Several techniques can be then used to apply strain to the specimens and thus to induce changes in their electronic structure. We will review their basic concepts and some of the examples so far documented experimentally and/or theoretically.

Flodrová, Dana ; Toporová, L. ; Macejová, D. ; Laštovičková, Markéta ; Brtko, J. ; Bobálová, Janette
Bottom-up proteomic approach was used for detailed characterization of proteins from\ntwo human tumour cell lines representing major clinically different types of breast\ncancer. The aim was to show the differences between them on proteomic level. Here\nwe present almost 100 unequivocally identified proteins out of which 60 were mutually\ndifferently expressed for MDA-MB-231 and MCF-7. Some well-known breast cancer\nmarkers like annexins A1, A2 and vimentin were found in the MDA-MB-231 cell line.\nOn the other hand, MCF-7 cells were found to be positive for cytokeratins and keratins\nand thus we were able to distinguish both cell lines sufficiently.

Modelling, parameter estimation, optimisation and control of transport and reaction processes in bioreactors.
ŠTUMBAUER, Václav
With the significant potential of microalgae as a major biofuel source of the future, a considerable scientific attention is attracted towards the field of biotechnology and bioprocess engineering. Nevertheless the current photobioreactor (PBR) design methods are still too empirical. With this work I would like to promote the idea of designing a production system, such as a PBR, completely \emph{in silico}, thus allowing for the in silico optimization and optimal control determination. The thesis deals with the PBR modeling and simulation. It addresses two crucial issues in the current state-of-the-art PBR modeling. The first issue relevant to the deficiency of the currently available models - the incorrect or insufficient treatment of either the transport process modeling, the reaction modeling or the coupling between these two models. A correct treatment of both the transport and the reaction phenomena is proposed in the thesis - in the form of a unified modeling framework consisting of three interconnected parts - (i) the state system, (ii) the fluid-dynamic model and (iii) optimal control determination. The proposed model structure allows prediction of the PBR performance with respect to the modelled PBR size, geometry, operating conditions or a particular microalgae strain. The proposed unified modeling approach is applied to the case of the Couette-Taylor photobioreactor (CTBR) where it is used for the optimal control solution. The PBR represents a complex multiscale problem and especially in the case of the production scale systems, the associated computational costs are paramount. This is the second crucial issue addressed in the thesis. With respect to the computational complexity, the fluid dynamics simulation is the most costly part of the PBR simulation. To model the fluid flow with the classical CFD (Computational Fluid Dynamics) methods inside a production scale PBR leads to an enormous grid size. This usually requires a parallel implementation of the solver but in the parallelization of the classical methods lies another relevant issue - that of the amount of data the individual nodes must interchange with each other. The thesis addresses the performance relevant issues by proposing and evaluation alternative approaches to the fluid flow simulation. These approaches are more suitable to the parallel implementation than the classical methods because of their rather local character in comparison to the classical methods - namely the Lattice Boltzmann Method (LBM) for fluid flow, which is the primary focus of the thesis in this regard and alternatively also the discrete random walk based method (DRW). As the outcome of the thesis I have developed and validated a new Lagrangian general modeling approach to the transport and reaction processes in PBR - a framework based on the Lattice Boltzmann method (LBM) and the model of the Photosynthetic Factory (PSF) that models correctly the transport and reaction processes and their coupling. Further I have implemented a software prototype based on the proposed modeling approach and validated this prototype on the case of the Coutte-Taylor PBR. I have also demonstrated that the modeling approach has a significant potential from the computational costs point of view by implementing and validating the software prototype on the parallel architecture of CUDA (Compute Unified Device Architecture). The current parallel implementation is approximately 20 times faster than the unparallized one and decreases thus significantly the iteration cycle of the PBR design process.

The Tax Assignation and Theater
Gerneš, David ; POKORNÝ, Jiří (advisor) ; VÁVROVÁ, Hana (referee)
Bachelor thesis aims based on an analysis support system theaters in the Czech Republic, the analysis of the tax system in the Czech Republic and analysis of tax assignations in the Slovak Republic, to investigate whether for the Czech theater network, this measure was beneficial and whether it would be worth it to deal with its introduction into practice. The thesis also examines the impact of the introduction of the assignation of income tax on Czech public budgets and polls. Within the survey sent to 120 respondents who were asked about their relationship to culture and whether they would be introducing a possibility for assignations and what area non-profit sector would contribute. On the basis of these steps is then designed a system of assignations suitable for Czech Republic.

Alternative methods of leading childbirth
PAPAI, Daria Kristina
The topic of my bachelor thesis is "Alternative methods of child delivery". The theoretical part describes the physiological delivery its particular phases and their progression. In addition, I aim to explain what the term alternative birth means, and what it includes. The various alternative positions are described, which can be used to facilitate childbirth, as well as their appropriate use during the particular delivery phases. The theoretical part is concluded by descriptions of pain relief methods, including the description of both pharmacological and non-pharmacological methods. The second part of the thesis is a practical part, summarizes the results of an evaluation research. The aim was to explore the most used alternative methods and to identify the views and experiences of women with alternative methods and aids used during delivery in selected hospitals. Furthermore, the aim was to describe the regions of the Czech Republic in terms of the use of alternative aids and procedures. The hypotheses were formulated based on previous experiences and personal opinions of the author of the thesis. The research sample consisted of women after a spontaneous child delivery in the České Budějovice Hospital and in the Znojmo Hospital. The research was conducted in the form of an anonymous questionnaire survey, using a non-standardized questionnaires. The results of the survey were compiled in tables and the chi-square test was applied as a method for statistical processing and verifying the hypotheses.

Effect of snowpack on runoff generation during rain on snow event.
Juras, Roman ; Máca, Petr (advisor) ; Ladislav , Ladislav (referee)
During a winter season, when snow covers the watershed, the frequency of rain-on-snow (ROS) events is still raising. ROS can cause severe natural hazards like floods or wet avalanches. Prediction of ROS effects is linked to better understanding of snowpack runoff dynamics and its composition. Deploying rainfall simulation together with hydrological tracers was tested as a convenient tool for this purpose. Overall 18 sprinkling experiments were conducted on snow featuring different initial conditions in mountainous regions over middle and western Europe. Dye tracer brilliant blue (FCF) was used for flow regime determination, because it enables to visualise preferential paths and layers interface. Snowpack runoff composition was assessed by hydrograph separation method, which provided appropriate results with acceptable uncertainty. It was not possible to use concurrently these two techniques because of technical reasons, however it would extend our gained knowledge. Snowmelt water amount in the snowpack runoff was estimated by energy balance (EB) equation, which is very efficient but quality inputs demanding. This was also the reason, why EB was deployed within only single experiment. Timing of snowpack runoff onset decrease mainly with the rain intensity. Initial snowpack properties like bulk density or wetness are less important for time of runoff generation compared to the rain intensity. On the other het when same rain intensity was applied, non-ripe snowpack featuring less bulk density created runoff faster than the ripe snowpack featuring higher bulk density. Snowpack runoff magnitude mainly depends on the snowpack initial saturation. Ripe snowpack with higher saturation enabled to generate higher cumulative runoff where contributed by max 50 %. In contrary, rainwater travelled through the non-ripe snowpack relatively fast and contributed runoff by approx. 80 %. Runoff prediction was tested by deploying Richards equation included in SNOWPACK model. The model was modified using a dual-domain approach to better simulate snowpack runoff under preferential flow conditions. Presented approach demonstrated an improvement in all simulated aspects compared to the more traditional method when only matrix flow is considered.
