The main topic of my thesis is the prevention of socially pathological phenomena and their implementation in low-threshold facilities for children and youth (NZDM). The work has two parts: theoretical and empirical. The theoretical part describes the socio-pathological phenomena, prevention, prevention programs and social services - NZDM general. In the empirical part is to find out the answer to the question, what is the impact of the implementation of prevention programs for service users in a particular device - in NZDM V.I.P.in Czech Budejovice, what should prevention programs in 2012 targeting and why, how often were made and what was the clients' interest in the topics of preventive measures.

In my dissertation I focused on the priorities of Bernard Bolzano o.p.s. school club in Tábor. In the theoretic part of my dissertation I mention leisure time in connection with children, historical development of leisure time pedagogy, functions, forms and activities of interest education, relationships and communication, definition of a school club and its advantages, school club participants, framework education programme and key competencies. In the practical part of the dissertation I made a research on priorities of a school club. On this basis I created various hypotheses. The veracity or inveracity of the hypotheses should have been verified by a questionnaire formed by research questions. Special additional questions of a structured dialogue with parents and educators of the school club served to specify the research. The evaluation of questionnaires and dialogues has brought the verification of the hypotheses.

This thesis deals with the legitimization of swimming in the selected children's home and school as a leisure activity. It defines the basic concepts to the topic with the help of case studies characteristics respondents, episodic interviews and field notes examines whether through the fitness swimming there could happen changes in the lifestyle of adolescents and if it corrects their behaviour. The aim of the research is to prove the above mentioned positive effects with the selected individuals and to legalize fitness swimming facilities in the same or similar types of organizations as a prevention of socially pathological phenomena.

The thesis talks about free time as a space for self-fulfillment in the context with the value change and the change of life style and concretely it analyses free time of the age group of adolescents, it describes their psychological development. The background part describes the historical development of free time, value change, value orientation and life style; it further deals with the question of self-fulfillment, life quality and the needs of an individual. The thesis captures the increasing importance of free time in the present society. The goal was to capture the importance of purposeful use of free time for today{\crq}s individual and its influence on the life quality. It is the purposeful use of free time, which works as a prevention of its possible pathology.

This doctoral thesis deals with biophysical interpretation of quantitative phase imaging (QPI) gained with coherence-controlled holographic microscope (CCHM). In the first part methods evaluating information from QPI such as analysis of shape and dynamical characteristics of segmented objects as well as evaluation of the phase information itself are described. In addition, a method of dynamic phase differences (DPD) is designed to allow more detailed monitoring of cell mass translocations. All of these methods are used in biological applications. In an extensive study of various types of cell death, QPI information is compared with flow cytometry data, and preferably a combination of QPI and fluorescence microscopy is used. The DPD method is used to study mass translocations inside the cell during osmotic events. The simplified DPD method is applied to investigate the mechanism of tumor cell movement in collagen gels.

In the last decade there is a rising interest in thermoelectric applications. Thermoelectric generators enabling the direct conversion of the heat into the electricity become attractive. This fact is caused by the demands of environmental operation and saving primary resources. Scientists intensively investigate and develop new materials and structures suitable for these applications. The efficiency of the thermoelectric conversion progressively increases. Unfortunately we have no available materials with sufficient thermoelectric properties which could provide cost-competitive price. Thermoelectric generators seem to be useable devices. For example, in case of the unused waste heat using of the thermoelectric generator can increase the overall effectiveness of the unit despite the low efficiency of the generator. This master thesis deals with the issue of the Peltier modules representing the main part of the thermoelectric generators. The physical principles and structures of the thermoelectric modules and the possibility of thermoelectric power production are described here. In the practical part of this thesis the design of the low power generator utilizing waste heat from biomass boiler Verner A 251.1 is proposed.

This master´s thesis provides an overview of all designs of check valves, their usage and typical features. Main purpose of this work is to clear up the phenomenon of check valve slam and the other problems that occur during transients. The check valve slam was measured at the test rig in the hydraulic laboratory. For unsteady flow evaluation after pump shut down was used Gibson method. The dynamic characteristic was possible to create by results from this method. It was achieved without impact of the speed of sound in the fluid. This work also contains 2D transient CFD calculations, which was used for evaluation of the hydrodynamic torque acting on the hinge pin. This approach provides an option to calculate wide range of cases at the expense of not entirely exact geometry. The main contribution of the theoretical study at the beginning of this thesis is its entireness. It might give an important clue when right valve is selecting. For good choice of valve might be helpful to use dynamic characteristics in this thesis presented. Mentioned characteristics were created by new way and its background is in measurements and simplified CFD calculations.

The aim of this master´s thesis is an explanation of the problem of transport optical networks with Dense Wavelength Division Multiplexing. DWDM principle, properties and limit of transmission system. Focus of thesis is also specification properties of migration transmission system to higher speed 40G, 100G and in future to 400G. Part of thesis is outlined the basic division of multiplexing system, there are discussed the basic solutions of wavelength multiplexes CWDM and DWDM, focus for the effects of nonlinear phenomena and parasitic modulation FWM, SPM and XPM in modulation DP-QPSK and 16-QAM. In practicle part we will make measurement of properties of 10G and then experimental measurement parameters on 100G.

The thesis is divided into two parts. Theoretical part consists of four chapters, empirical investigation, the practical part.Chapter one focuses on the notion of family and its importance. Except for clarification of the concept are described the basic characteristics of the family now, basic functions of the family and educational styles. Conclusion of the firts chapter looks at the family as a potential risk factor of development and socio-pathological behavior in children and adolescents. The second chapter explains the basic concepts of social deviance and social pathology and describes the main causes of social pathologies. The third chapter describes the various social pathologies, which pose the greatest risk for the age group of children and adolescents. There are described in more detail: dependence on psychoactive substances, aggression and violence, vandalism, bullying, cyber crime and delinquency and pathological gambling. The fourth chapter is devoted to prevention, especially for a preventive action in the family. Practical part is an empirical investigation, in which the case study of ten children and adolescents who have committed some form of pathological behavior.

In comparison with the art production at Nurnberg or at the cities of the so-called Danube School at the end of 15th century stands the simultaneous painting at Munich in the background. Therefore is sometimes forgotten, that there, in this period, a painter Jan Polack with his workshop was active. To his important customers/patrons belonged the dukes Sigmund and Albrecht of Wittelsbach and the Bavarian monasteries (Weihenstephan near Feising), for which he made few altars or portraits. A most of these altars were after that removed from the original sacral areas and today they are presented in the Bavarian National-museum at Munich or in other galleries. Only a few altars, for example three altars for the chapel in Blutenburg near Munich, have been staying on the original place in this small chapel. These Master thesis would like to compare his most representative pictures in the context with the others paintings, which were created in the middle or at the end of the 15th century in Bavaria (circle of Hans Pleydenwurff, Wolfgang Katzheimer etc.). This comparison can help to find the sources of the Polacks artistic expression. A special attention should be devoted his cooperation with Mair of Landshut, because few pictures of Polacks altar from the church of St. Peter in Munich have just been to Mair inscribed. It is also important to point to same compositional connections between the altar-pictures of Jan Polack and the graphics (Master E. S., Martin Schongauer) One highly-valued contribution of this thesis could be a capitol about the possible inspiration of the Polacks artistic expression for the artists, who came from Bohemia and who have been working here for a long times, but who could gain their training in the Bavaria (Munich). At the literature (Jaroslav Pešina) was one opinion expressed, that an altar in a church in Chudenitz concludes the formal features, which reveal a connection to the art at Munich in the middle of the 15th century. However, other authors (Roman Lavička) think that the painted boards of an original altar of Doudleby were inspired by Polacks artistic expression, although any concrete related features were not in the literature mentioned. It is appropriate too, point to the several compositional connections between the pictures of Jan Polack und a so-called Master of an altar from Litoměřice. This anonymous Bohemian painter, who is knowed only according to his most important commission, would be supposed to study in the Bavaria (an artistic circle of Rueland Frueauf at Passau) at the end of the 15th century. It is possible, that he could visit Munich und he could be inspired by the Polacks paintings.
