Changes to rights to claim foster care benefits since year 2013
ZEMANOVÁ, Hana
Foster care is a form of social care in the Czech Republic. A fostered children and foster parents receive from state a foster care benefits. Up until 2012 these benefits were set by Act No. 117/1995 Coll., on State Social Support. In 2012, Amendment No. 401/2012 Coll., transferred foster care benefits to Act No. 359/1999 Coll., for Social-Legal Protection of Children. With this change in law, there was also a change in the conditions of entitlement to claim foster care benefits and the establishment of efforts to professionalize foster care. The aim of my work is to analyse and compare the legislation of changes to foster care benefits from the perspective of the State Social Support Law and the Law of Social-Legal Protection of Children. I have tried to confirm or invalidate the hypotheses using quantitative research, this forms the empirical part of my work. Hypotheses were focusing on comparing the situation before and after the changes of Law for Social-Legal Protection of Children. As a technique I chose to study documents and using these documents I have provided secondary analysis. I have worked with the statistics of the Ministry for Labour and Social Affairs of the Czech Republic, the Labor Offices and the Regional Offices. The results of my findings have shown that more foster parents should be able to claim foster care benefits. Passing the bill on professional foster care has increased the interest in providing foster care, this must be seen as positive outcome. My research could be used as study material for other students of social science or for people who work in the area of social-legal protection of children. It could also be used as feedback for ministerial officials to sea the real situation since the changes in foster care law.

Anti-Plague texts in the late Middle Ages and the Early modern period.
PAMPUSCHOVÁ, Marie
The theme of this work are late medieval and early modern time anti-plague treatises and official regulations against plague. In times when many countries and even continents were affected by plague, many city councils and rulers themself had the treatises printed in order to reduce the risk of transmission of the infection and development of the illness. The treatises adjusted regulations of towns and villages. These official decrees against plague were supplemented with plague treatises that were written for inhabitants of towns affected by black death. Many of them were written in Latin and therefore incomprehensible to uneducated people. It changed when a doctor Jan Černý wrote such a treatise in Czech language. The treatises advised not only how to prevent plague but also how to treat it. I divided my work into two parts. In the first part I describe particular plague epidemics that took place especially in Bohemia and Moravia. I progressed chronologically from antiquity to the 18th century and described whole course of epidemics in various regions. In the second part I focused mainly on different ways how these treatises deal with prevention and treatment of the disease. I made a comparison of various plague treatises from Prague, České Budějovice and Nepomuk. In order to gather data and informations I focused on historical sources and literature that give us informations from people who had first-hand experience of plague. I do the overall comparison and critique of these sources in seperate chapter. I believe this work can work as an educational material for students and teacher

Optimalization of material flow in automotive industry
Kolář, Tomáš ; Jirsák, Petr (advisor) ; Vinš, Marek (referee)
This master thesis is focussed on optimalization of material flow in an automotive company. First part introduce theoretical background. Automotive industry and its actual trends on global markets. Follows short introduction of the company where project of this thesis was executed. Main theoretical part describes concept of lean management, its tools in practical examples, but it is also focussed on philosophical approach to the work and mindset of the company. Follows the aplication part based on theoretical background. The whole project of this master thesis is focussed on specific area called PC store. At first this area is showed in context of overall material flow. Shortly there are introduced processes and areas where full material packaging flows. Follows deeper analysis and optimalization of PC store itself. There are three approaches of stock and lead time reduction applied. Last part shows the comparison of initial and future state including performed changes.

INFLUENCE OF LASER CUTTING AND PUNCHING ON MAGNETIC PROPERTIES\nOF ELECTRICAL STEEL M470-50A
Bulín, Tomáš ; Švábenská, Eva ; Hapla, Miroslav ; Ondrůšek, Č. ; Schneeweiss, Oldřich
Electrical steel M470-50A belongs to the most often used materials in electrical machines. Due to this fact, it is desirable to know the magnetic parameters after processing raw sheets into the required shape. Basic parameters of mechanical, electrical, and magnetic properties of the sheets are usually obtained from the producer but the magnetic properties are changing in dependence on additional machining processes. The aim of this study is to describe changes in parameters of magnetic behavior after punching, laser and spark cutting of the original sheets. The basic information of structure was obtained by optical and scanning electron microscopy. The magnetic parameters were acquired from the measuring of magnetic hysteresis loops in dependence on saturation fields and frequencies. The results are discussed from the point of view of applied\ncutting technology with the aim to obtain the best magnetic parameters and consequently a higher efficiency of the final product. Results can be used as input parameters in simulation of the electrical machine.

Changes in structure and phase composition in the surface of tram rail
Švábenská, Eva ; Roupcová, Pavla ; Schneeweiss, Oldřich
We have investigated structure and phase composition of surface layer of tram rails after long time running and the results were compared with those obtained on the original part of material. Changes due to effects of severe plastic deformation together with thermal shocks by friction process were expected. The information about structure and phase composition was obtained by optical and scanning electron microscopy, X-Ray Powder Diffraction, Mössbauer Spectroscopy and Glow Discharge Emission Spectroscopy (GDOES) and this was completed by microhardness measurements. The results show that the surface layer in comparison with the original material exhibits important changes in grain structure, an increase in microhardness and high content of iron oxide and hydrooxides. According to the depth profile of the chemical composition measured by GDOES there is an increase in carbon content in the surface layer which can be effect of up-hill diffusion.

Satisfaction of women in labour with nursing care during childbirth.
KLÍMOVÁ, Magdaléna
This dissertation investigates the level of satisfaction among expectant mothers with the care services provided during childbirth. Satisfaction reflects a subjective perception of an expectant mother in meeting her needs during childbirth. The feeling of satisfaction is very personal, however, evaluation of the care provided needs to be determined and not ignored. It is important for expectant mothers that the health care professionals present as empathic, friendly, co-operative, and tactful.Theoretical part was developed from evidence-based literature and available findings related to this problematic. There is a description of a childbirth process including a midwife's role during the individual stages of childbirth and options for pain management. Other chapters focus on midwife's approach toward an expectant mother and factors which influence the level of satisfaction during childbirth. Dissertation's aim was to determine whether the expectant mothers were more satisfied in smaller maternity departments, and to evaluate the way a midwife may influence the mother's satisfaction. There were two hypotheses stated and verified by a statistical testing. Hypothesis No. 1: Expectant mothers are more satisfied in smaller maternity departments than larger ones. Hypothesis No. 2: The level of satisfaction is influenced by midwife's empathic approach. Practical part focused mainly on a midwife's approach toward expectant mother. A quantitative research was implemented in form of questionnaires. The research sample constituted of expectant mothers from four postpartum departments in the Czech Republic. In total the sample included 215 expectant mothers, 109 from smaller facilities and 106 from larger maternity departments. In terms of the overall level of satisfaction with their midwife during the childbirth process, 89% of expectant mothers from smaller maternity departments and 83% of expectant mothers from larger departments stated they were satisfied. Conversely, 11% of respondents from smaller facilities and 17% of respondents from larger facilities were dissatisfied. Based on research analysis comparing the level of satisfaction of expectant mothers from smaller and larger maternity departments the hypothesis no. 1 "Expectant mothers are more satisfied in smaller maternity departments than the larger ones" did not show as statistically significant and was rejected. Nonetheless, the questionnaire responses clearly showed that empathic approach of a midwife influenced expectant mother's satisfaction. Statistical testing demonstrated a significant correlation between an expectant mother's satisfaction and empathic approach of a midwife. The second hypothesis "The level of satisfaction is influenced by midwife's empathic approach" was accepted.The research findings may serve as a guiding material for the midwives in order to provide a high quality care to expectant mothers during the childbirth process. They may also be utilised by future midwives who are in undergraduate preparation for the profession, or those professionals who contribute in any way during the childbirth process. Additionally, the research findings may be presented at conferences designated for midwives.

Plasma spraying from liquids: plasma liquid interaction and coating build up
Tesař, Tomáš ; Mušálek, Radek ; Medřický, Jan ; Lukáč, František
Plasma spraying from liquid feedstocks is a rapidly developing field of thermal spraying since the coatings prepared from liquids exhibit some unique features, such as high hardness, thermal shock resistance or low thermal and electric conductivity. The key factor influencing the final coating character and properties is the input material which may be in the form of a suspension or a solution. Parameters of the selected suspension (solids concentration, viscosity, surface tension, chemical composition, etc.) or solution (concentration, etc.) determine its interaction with the plasma jet which strongly influences the coating buildup. This proceeding introduces the problematics of the interaction between the liquid feedstock material with the plasma jet and presents the way of evaluation of the coating buildup.
