Problems of the small municipalities in the Czech Republic with respect to the functioning and effectiveness of the public administration
Klusáček, Petr
The contribution deals with certain issues which are connected with the third period of the current public administration reform in the Czech Republic. The attention is paid especially to the functional aspects of the above-mentioned reform. From hierarchical point of view, the contribution is focused on the municipal level, where exist the most significant disparities caused by large occurrence of the small municipalities (defined as a municipality up to 1 000 inhabitants). The main objective is to find the most suitable measures and tools, which could be implemented in future to achieve improvements in the functioning and effectiveness of the public administration on the territory of the Czech Republic.

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.

NUMERICAL ESTIMATION OF MICRO-CRACK PATHS IN POLYMER PARTICULATE COMPOSITE
Majer, Z. ; Náhlík, Luboš
Determination of composite mechanical behavior is one of important part during the composite tailoring. The aim of the present work was to estimate a micro-crack behavior in a polymer particulate composite. The composite was investigated by means of the finite element method -using ANSYS software. A two-dimensional three-phase finite element model was developed to analyze the crack growth behavior. The assumptions of the linear elastic fracture mechanics were considered and the Maximum Tangential Stress (MTS) criterion was used to predict the direction of the crack propagation. The effect of the elastic modulus of the interphase on the micro-crack propagation was investigated. The properties of matrix and particles were taken from experiment. It was shown that the interphase properties influence the stress intensity factor KI as well as the micro-crack paths. The results of this paper can contribute to a better understanding of the micro-crack propagation in particulate composites with respect to the interphase.

On Motivation of Moravian and Silesian Anoikonyms Derivate from the Appellative kámen
Šimečková, Marta
This paper deals with motivation of Moravian and Silesian minor place names containing the basic noun kámen ‚stone‘, e. g. Kameňák (the suffix -ák was attached to the respective noun to create this anoikonym), Kamenice (with the suffix -ice), Kamenička (with the suffix -ička). There are numerous motivations, the most frequent is the motivation of soil quality and of location (especially in prepositional anoikonyms, for example Mezi kamencem, Na kamenici). Other motivations are rare: motivation of a particular stone as significant part of the landscape, motivation of building material or stone mining. The frequency of these motivations is different from the frequency of motivations in underived anoikonyms (or anoikonyms containing plural form of the fundamental word Kameny; in this type of anoikonyms, motivation by a particular stone in the site is more frequent). The motivation is hard to determine in some cases, the interpretation can be impeded by bachelor's etymology therefore it is necessary to cooperate with old maps.

Small Size Municipality Revenues in Czech Republic
JIREKOVÁ, Kateřina
The aim of this thesis is to evaluate the system of municipality incomes in the Czech Republic with respect to specifics of small municipalities. In last few years these municipalities have become a frequently discussed topic because of their lower incomes. The legislation has been devoting to this problem since 2008 and the differences between large and small municipalities in the Czech Republic were removed. There is income analysis of all municipalities in the Czech Republic from 2000 up to 2012 in this thesis. The municipalities were divided into two groups. The first group contains small villages, defined as municipalities up to 499 inhabitants. In the second group there are other municipalities of the Czech Republic except small villages, statutory cities and the Capital City of Prague. The real data were recalculated per head for this analysis and minimum, maximum, median and arithmetic mean were found. Variability of incomes is evaluated from these results. Regression and correlation analysis is made in some groups of revenues because of finding dependence among variables. Disparity in incomes of small towns and other communities is assessed by comparing the arithmetic means and medians between groups of municipalities using a Two-Sample t-test and Mann-Whitney test. Revenue growth is evaluated determination of the trends of the time series using linear regression. Some specifics in financing small villages were found from these analyzes. There was also confirmation of the hypothesis that small municipalities have lower incomes per an inhabitant.

Project management in selected company
POKORNÝ, Radek
This work deals with project management in chosen company. It has two parts. The first part is theoretical, which is focused to theoretical treatment of the subject. It explains what is the project, management of projects, organizations of projects, processes of project management, what is target of project, communication, control, changes and risks and more. In the practical part I focused to concrete company and project management and than I analyzed concrete project. Name of the mentioned company is OHL ŽS, a.s. It is company from Spain, which acts all over the world. In the Czech Republic has the base in Brno. This company has several divisions and every of them is focused to different professional architecture. I have chosen division of structural engineering. This division builds all kinds of buildings. It could be construction of new buildings or reconstruction. To analysis of chosen project I used various business documents, contracts with investor or suppliers, document which include billing, timetable. I especially used my experience with projects of this company, and I was part of this project. Name of this project is Reconstruction of cladding including replacement windows and insulation. During the analysis of project I found a couple major gaps. If we could avoid these gaps, we could increase profit. These graphs is especially in management. At the beginning there were appointed two temporary construction managers. They doesn't care about result project, because they knew that they will not be to the end of the project. These gaps are because there is missing motivation system. Project manager can´t affect results of employees. It doesn´t depend on performance of employees, they always has the same wages. For elimination of these gaps I proposed several suggestions for improvement. The first suggestion is modification and extension of motivation system. New motivation system include personal evaluation. This evaluation depends on performance of employee. The second part is bonus from over profit. The next suggestion is make a new working position. This position would take care about controlling and project documentation. During the building project, especially at the end is construction manager very busy. It depend of decision of construction 63 manager what kind of activity will have prefer. Project documentation and administration or controlling of building works. If they are doing everything correct and technology are respect. Suggested position would take care about invoices, real work, which is done, project documentation, controlling of budget. The third suggestion is purchase of small machinery such as chipping hammers and drills. At this time they rent all devices. Rent is higher than purchase price. The last suggestion is use credit to restoration of fleet. At this time they have obsolete fleet, because the bought all cars by cash. It is not conveniently.

Distribution of CD46 and β1 integrin molecules with respect to different membrane structures of the sperm head
Šebková, Nataša ; Frolíková, Michaela ; Děd, Lukáš ; Dvořáková-Hortová, Kateřina
CD46 protein plays an important role during fertilization and its role is associated with acrosome stability. CD46 is probably involved in signalling pathways triggering the acrosome reaction (AR). It also associates through membrane integrins with specific MAP kinases involved in the AR. Our aim was to monitor the dynamics of relocation of CD46 and β1 integrin during sperm maturation and its preparation for the fertilization. The dependence of this localization changes on the dynamic of actin cytoskeleton was studied. Our results show the changes in the localization of these proteins associated with the AR and their co-localization was observed using proximity ligation assay. After the AR CD46 and β1 integrin spreads across the sperm head, entering the post-acrosomal compartment, and permeates the borders of different domains. It was shown previously that actin dynamics is necessary for acrosome reaction-associated translocation of Izumo1 protein that is required for sperm-egg fusion. Therefore Latrunculin A was used during sperm incubation. The co-incubation of capacitated sperm with Latrunculin A leads to a decrease of the percentages of sperm, which express relocation pattern after induced AR. 3D models and visualizations of potential membrane processes responsible for the relocation of proteins from the acrosomal area to the other compartments of the sperm head were prepared. Our results deliver new information that proteins CD46 and β1 integrin undergo dynamic relocation towards the sites of sperm-egg fusion during the AR in vitro. The inhibitor of actin dynamics abrogates significantly the AR-associated changes in proteins localization. We speculate that this relocation is of importance for the successful sperm-egg interaction, adhesion and subsequent gamete fusion.

Nursing care management of patients after intrapleural chemical pleurodesis
KIESEWETTEROVÁ, Renáta
The pleurodesis is a treatment method for patients suffered from the symptomatic malignant pleural effusion. The goal of the pleurodesis is to close a pleural area by connection of visceral and parietal pleura in order to reduce or terminate production of pleural effusion. The sterile talc powder is the world's most used agens within a practice. After a parental analgesic is the powder (as a sllury) either applicated into a pleural cavity through the chest drainage or surgically dispersed over the treated (via abrasion, decortication) pleural space during the thoracoscopy/thoracotomy. This diploma thesis focuses on the treatment technique of bedside talc-pleurodesis through the chest drainage. The nurse has an irreplaceable role in the whole process from a preparation of patient to assistance by intrapreural application, to care of patient after the operation or serves as a physical support during potential complications. The aim of the presented work is to detect priorities in nursing care and find out whether patients need increased care after intrapleural therapy. The qualitative research method was chosen for the analysis where semi-structural interview with open questions were used. We created case reports analysed with the adaptive model of Callista Roy as well. The research sample contained patients chosen with respect to specialization of researched problem. We set two basic focal stimuli according to the analysis of respondents´ reactions. These stimuli serve as a basis for determination of priority parts of the nursing care by patients after bedside pleurodesis. We defined the need to be without pain and the need to ensure safety and certainty as a central focus of the nursing care. Among secondary fields of nursing care were identified sleep disturbances and limited mobility, which leads to reduction of self-care in getting dress, hygiene as well as in defection and miction. We found out within the second goal identical intensity of the nursing care before and after bedside talc-pleurodesis. This statement is based on comparison of interventions before and after aplication analysed via adaptive model by Roy. Nevertheless, causes of interventions were modified to a certain extent. The main goal of diploma thesis was to map requirements for high-quality nursing care related to bedside talc-pleurodesis via chest drainage. The work should extend theoretical basis not only for nurses in clinical practice.

Stress situations and nursing personnel
MAREŠOVÁ, Lucie
This thesis deals with the stressful situations in the profession of the nursing staff. The occupation of the nurse belongs to the most demanding ones. In this occupation, the nurse is permanently affected by many stressors of different types. She faces death, the suffering, dying and incurably ill people very often. She is there in times of pain, agony and suffering. Personal encounters with these difficult situations require highly professional approach but most of all, they present immense work stress for the nurse. The theory section describes mainly the stressful situations that are the most common and most difficult in the work of the nursing staff. The next part of the theory section describes possible consequences of the stressful situations and methods of managing them including the support by the management. This thesis has two objectives. The first objective was to map the manners used by the nursing personnel to cope with the stressful situations brought by their profession. The second objective was to find out the difference in the coping with the stressful situations between the hospital staff and hospice staff. The research section of this thesis contains the quantitative research done using the technique of an anonymous questionnaire with 20 question prepared by ourselves. The questionnaire was distributed to the nursing staff of all categories in the hospital and hospice care. It was completed by 269 respondents in total. The data was statistically processed using systems Microsoft Excel 2010 and Software R, version 3.0.2 (Chi-squared test, Fisher´s exact test, and Wilcoxon test). We determined four hypotheses. H1: Manners of coping with the stressful situations depend on the qualification of the nursing staff reached; not confirmed. H2: Manners of coping with the stressful situations are influenced by the length of practice of the staff; not confirmed. H3: Manners of coping with the stressful situations differ between the hospital staff and hospice staff; confirmed. H4: The nursing staff views their own mental hygiene as more efficient than the support from the management concerning the coping with the stressful situations; confirmed. The research results show that the nursing staff faces the stressful situations very often. They see as the heaviest stress the care of the suffering and aggressive patient, conflicts with the patient´s family, conflicts at work and workload. The manners of coping with the work burden which proved as the best for them are relax, rest and sleep. There were no differences proved in the manners of coping with the stress among respective members of the nursing team. Nevertheless, the coping with the work burden of the nursing staff in the hospital and hospice care is different. A minimum of the respondents notices any support during the stressful situations from the employer. On the other hand, certain support by the management could be viewed in the form of trainings, supervision or contribution to a "recovery" which are granted to the respondents from the employer according to their answers. However, the respondents would prefer, as the support by the management, the increase in pay or more days off. The respondents view as insufficient the preparation of the graduates for the future stressful situations in their profession, as well. They would recommend mainly various trainings dealing with the stress and its management. A good solution to alleviate the work burden of the nursing staff and quality enhancement of the services provided could be investments into better work conditions, both in terms of sufficient human and material resources and the very organization of the work processes.

Land Abandonment in the Mediterranean Effects on Butterfly Communities with Respect to Life History Traits
ŠLANCAROVÁ, Jana
This thesis deals with the effects of changing land use, following landscape abandonment, on butterfly communities in the Mediterranean Basin. It consists of three case studies. The first focuses on the effects of forest encroachment on butterflies in the Southern Balkans; the second studies butterfly communities in Portuguese 'montados' and the third explores demography and life histories of three co-occurring Papilionidae butterfly species (Archon apollinus, Zerynthia polyxena and Zerynthia cerisy) in Greek Thrace. The results describe shifts in butterfly communities, detectable even at the level of individual species life history traits, with increasing forest encroachment. The preference of range-restricted Mediterranean endemics for either grasslands or open woodland formations contributes to falsifying the forested Mediterranean hypothesis, favouring a hypothesis of finely grained landscape mosaic instead. This mosaic is currently threatened by land use change and biodiversity homogenisation. Maintaining habitat and landscape heterogeneity is crucial for conserving the Mediterranean biodiversity hot-spot.
