Schneeweiss, Oldřich ; Pizúrová, Naděžda ; Jirásková, Yvonna ; Žák, Tomáš ; Bezdička, Petr ; Večerníková, Eva
We have prepared MgO-Ni(Fe) nanocrystalline composites by controlled heat treatment of compacted spark synthesized nanocrystalline powders. Besides particle sizes and their chemical compositions, influence of interaction with surrounding atmosphere and adsorbed gases on phase composition and magnetic properties were investigated. Mössbauer spectroscopy, x-ray diffraction and TEM were used for phase analysis. Thermomagnetic curves and DTA/TG measurements were applied for detection of changes in structure and phase composition during heat treatments. The simultaneous gas analysis using mass spectroscopy by heating yielded information on adsorbed and dissolved gases and their reactions with the nanoparticles.

The migration crisis in Europe and subsequent implications for Swedish welfare state
Lacková, Dominika ; Bič, Josef (advisor) ; Němcová, Ingeborg (referee)
In general, migration is one of the most important global challenges. The topic of regulating migration flows came to the fore in relation to the current Europe's migration, or more precisely, refugee crisis. It has been described as the most massive migrant's crisis since the WW2. Unprecedented influx of immigrants and refugees in 2015 resulted in that even the best prepared European countries, such as Sweden, have reached a tipping point with regard to respect EU standards related to reception and processing of asylum applications. Master thesis covered two main analyses - the relevance of the refugee crisis in the EU in regards to the Swedish welfare state and the subsequent implications arising from the refugee crisis for the Swedish welfare state.

The role of nurse in the care of child patient with hemangiom.
ŠESTÁKOVÁ, Růžena
One of the most important areas of society-wide tasks influencing the health of the whole population is child care. It includes care of children with a hemangioma. Hemangiomas are the most common benign (not malignant) vascular tumours of a child age. This benign tumour may be present as early as at birth or appear in the first weeks of life. It is usually located on or under the skin surface but may also affect internal organs. Although a hemangioma may affect any body part, it is mostly located on the head and neck. A hemangioma is diagnosed in a tenth of new-born children. Hemangiomas typically appear at neonatal age or infancy. The objectives of the diploma thesis "Nurse's Roles in Care of a Child Patient with a Hemangioma" are to examine the roles of nurses in care of a child patient with a hemangioma, as seen by parents (mothers) of the children, and to identify which of the roles is the most important for the parents (mothers). It has also been ascertained whether nurses deal with any problems while providing this care and whether occurrence of a hemangioma in a child has any influence on the child's family. It has also been ascertained whether any complications are encountered in the treatment of children with a hemangioma. A qualitative research was used for data processing. Several methods of data collection were used. The researcher used a case history according to the model of Virginia Henderson, semi-structured interview with mothers of patients, data content analysis and secret participant observation during outpatient checks. The last method used was a survey aimed at nurses who took care of children with a hemangioma, asking them whether they dealt with any problems and complications in such children. The first research set consisted of ten child patients who were selected on purpose on the basis of pre-set criteria. The first criterion was presence of a hemangioma; five patients were hospitalised with a hemangioma and underwent a treatment with propranolol, while the other five patients with a hemangioma underwent only a conservative treatment. Last but the most important criterion was that mothers of patients with a hemangioma granted their consent to the research. These mothers formed the second research set and underwent a semi-structured interview focused on their personal experience with a hemangioma and on the work of nurses as seen by mothers. The last research set consisted of ten nurses who were also selected on purpose on the basis of a very important criterion, which was care of child patients with a hemangioma. This thesis may be of a benefit not only for professionals who are in contact with children with a hemangioma but may also serve to deepen general knowledge of other healthcare professionals who may encounter this disease either in their professional or private life. Based on the information acquired for the diploma thesis, was prepared for nurses and will be presented at professional workshops.

Progress, outcome, future scenarios and threats of multilateral trading system (WTO)
Kozáková, Michaela ; Štěrbová, Ludmila (advisor) ; Trojanová, Kamila (referee)
This diploma thesis aims to set a complex view on the current process of multilateral trade agreements under the World Trade Organization and point out the direction of DOHA negotiations. The emphasis is put on the Tenth Ministerial Conference, which took place in Nairobi in December 2015. Stances and demands of the WTO member are analysed step by step. The thesis considers threats that possibly come from plurilateral, bilateral and regional agreements and evaluate a potential risk for the multilateral trading system. For this purpose, the thesis is divided into four chapters. First chapter examine theoretical introduction to WTO and particularly to Development Doha Agenda, which is important for subsequent understanding of actual issues. Second part analyses in detail the negotiations in main negotiating parts of DDA before and after a summer break. Following chapter fluently continues with analyse of the progress after summer break and points out some current questions about preparations for MC10 and expectations. Space is also given to the MC10 and its outcomes. Finally, the last chapter gives a thought to future scenarios concerning function of the WTO.

CRM System Optimization
Fučík, Ivan ; Mildeová, Stanislava (advisor)
This thesis is focused on CRM solutions in small and medium-sized organizations with respect to the quality of their customer relationship. The main goal of this work is to design an optimal CRM solution in the environment of real organization. To achieve this goal it is necessary to understand the theoretical basis of several topics, such as organizations and their relationship with customers, CRM systems, their features and trends. On the basis of these theoretical topics it is possible to analyze current CRM solution in the organization. From the data obtained by the methods of observation and controlled interview it was possible to prepare a design for optimal CRM solution. This optimal solution comes also from user and organization requirements. The optimal CRM solution saves time and costs associated with current CRM solution and replaces existing and ineffective CRM tools.

Verníček, Marek ; Molnár, Zdeněk (advisor) ; Šperková, Lucie (referee)
The main purpose of this thesis is to investigate the use of Big Data for the methods and procedures of Competitive Intelligence. Among the goals of the work is a toolkit for small and large businesses which is supposed to support their work with the whole process of Big Data work. Another goal is to design an effective solution of processing Big Data to gain a competitive advantage in business. The theoretical part of the work processes available scientific literature in the Czech Republic and abroad as well as describes the current state of Competitive Intelligence, and Big Data as one of its possible sources. Subsequently, the work deals with the characteristics of Big Data, the differences from working with common data, the need for a thorough preparation and Big Data applicability for the methods of Competitive Intelligence. The practical part is focused on analysis of Big Data tools available in the market with regard to the whole process from data collection to the analysis report preparation and integration of the entire solution into an automated state. The outcome of this part is the Big Data software toolkit for small and large businesses based on their budget. The final part of the work is devoted to the classification of the most promising business areas, which can benefit from the use of Big Data the most in order to gain competitive advantages and proposes the most effective solution of working with Big Data. Among other benefits of this work are expansion of the range of resources for Competitive Intelligence and in-depth analysis of possibilities of Big Data usage, designed to help professionals make use of this hitherto untapped potential to improve market position, gain new customers and strengthen the existing user base.

Sperm protein profiles of different mammalian species
Pohlová, Alžběta ; Zigo, Michal ; Jonáková, Věra ; Postlerová, Pavla
Proteins are a substantial equipment of the spermatic cell; therefore, the characterization of sperm proteins is crucial for explanation of molecular mechanisms in the reproduction process. We isolated sperm proteins from different mammalian species - pig, bull, human, mouse, dog and cat. Extracted proteins were separated by SDS-electrophoresis and protein/glycoprotein profiles from epididymal or ejaculated sperm were compared. Additionally, we tested cross-reactivity of antibodies prepared to sperm boar proteins on spermatozoa of other mammalian species using immunofluorescent technique. Our future plan is to compare the protein profiles of sperm during their functional development (epididymal, ejaculated, capacitated) in various mammalian species and identify species-specific sperm proteins with zona pellucida binding activity.

Role of Psb28 proteins in the biogenesis of the Photosystem II complex in the cyanobacterium Synechocystis sp. PCC 6803
BEČKOVÁ, Martina
The thesis focuses on the role of Psb28 proteins, namely the Psb28-1 and its homolog Psb28-2, in the biogenesis of the Photosystem II complex (PSII) in the cyanobacterium Synechocystis PCC 6803. The aims of this work were to localize the proteins within the cells, and to determine their function. A fraction of both Psb28 proteins was identified in the monomeric PSII core complexes but most proteins were found in the unassembled protein fraction associated with thylakoid membranes. Psb28-1 was mostly detected as a dimer while Psb28-2 as a monomer. Psb28-1 also differed from Psb28-2 by its higher affinity to the PSII core complex lacking CP43 antenna. Characterization of Psb28-less mutants suggested regulatory function of the proteins in PSII biogenesis in connection with chlorophyll biosynthetic pathway. Analysis of preparations isolated using FLAG-tagged versions of Psb28 proteins showed their association with Photosystem II - Photosystem I supercomplexes, especially under increased irradiance, and supported a role of Photosystem I in the PSII biogenesis.
