Obesity and Obesogens
Dvořáková, Jana ; Müllerová, Dana (advisor) ; Houdek, Zbyněk (referee) ; Štich, Vladimír (referee)
The prevalence of obesity has already epidemic dimensions. Recently, the obesogens have been identified as the main cause in addition to excessive food intake, the lack of physical activity and the genetic background. These substances damage the metabolic processes, interfere with the hormonal functions and impair the energy balance in behalf of gaining weight and obesity. The theoretical part of this work deals with obesity, adipose tissue, lipid droplet and obesogens. From the obesogens there is closely specified a group of persistent organic pollutants (POP) from which one representative was used in the practical part of this work. The aim of the practical part was to describe the cellular model of differentiation the mesenchymal stem cell into adipocytes and to investigate the effect of one of the most frequently occurring obesogen on the expression genes of lipid metabolism and insulin signalling pathway. The morphological changes were observed in cells during differentiation (at days 0, 4, 10 and 21). The mesenchymal cells of the elongated spindle shape changed into adipocytes filled with lipid droplets. Oil Red O staining was used for quantification of accumulated lipids. The differentiation to adipocytes was confirmed by fluorescence immunocytochemistry using a specific protein FABP4. The...
Creation of instructional materials for selected sports leisure activities of children with visual impairment
DVOŘÁKOVÁ, Jana
This bachelor thesis is focused on the methodology of teaching selected sports activities in schools for pupils with visual impairment. For the purpose of this thesis there were chosen three sport activities: ice skating, cycling and swimming. The aim was to create videos that will serve as instructional material for physical education teachers in schools for pupils with visual impairment, but also for parents of pupils with visual impairment. The theoretical part defines terminology and legislation connected with the issue of teaching physical education of pupils with visual impairment. The following chapters describe the current educational system of children and pupils with visual impairment. The theoretical part concludes with a description of the methodology of ice skating, cycling and swimming, which is modified for the needs of pupils with visual impairment. The practical part is based on interviews with teachers who teach physical education at primary schools for pupils with visual impairment. Based on these interviews, instructional videos that describe the methodology of teaching skating, swimming and tandem biking to pupils with visual impairments have been created.
Motivation, reward and punishment in primary education and their practical application
Dvořáková, Jana ; Dolista, Josef (advisor) ; Blažková, Miloslava (referee)
The aim of the diploma thesis is the theoretic description of forms of motivation, rewards and punishments applied on elementary school pupils. The research was aimed at the individual forms of motivation, rewards and punishments that respondents apply in their teaching and what the effects are. Theory and practice are compared with the intention to highlight attitudes and features that are applied by teachers in the fields of motivation, rewards and punishments. Consequently, the agreement of forms of motivation and rewards for pupils described in the literature and their application of practical teaching at the elementary school was confirmed. However, the point the academic literature and applied practice differs were the forms and methods of pupil's punishments. Opinions about applied forms of punishment have been diverged by individual interviewed teachers although researched file shows considerable agreement in the previous two topics. The purpose of the thesis is to acquire an outline and detailed information about the given issue and their subsequent comparison with the practice knowledge. The thesis also enriches the theoretical resources with the real experience and whatsoever, there is a general monitoring of the approach of elementary school teachers to this issue. The practical part proceeds in...
The effect of pyrazine derivatives on the secondary metabolites production in in vitro cultures of medicinal plants I.
Dvořáková, Jana ; Tůmová, Lenka (advisor) ; Kašparová, Marie (referee)
The aim of this work was to investigate the effect of pyrazine derivative, 1-octyl-3-(pyrazin-2- yl)urea, as an abiotic elicitor on the production of flavonoid rutin in in vitro cultures of Fagopyrum esculentum Moench., Cultivar Bamby. Suspension and callus cultures were cultivated on Murashige and Skoog nutrient medium (MS) with the addition of 2,4-dichlorophenoxyacetic acid (2,4-D) as growth regulator at a concentration of 1 mg/l. The elicitor solution was added to the cultures at three concentrations: c1 (100,0 mg/100 ml), c2 (10,0 mg/100 ml) and c3 (1,0 mg/100 ml). The elicitor was monitored at six time intervals: 6, 12, 24, 48, 72 and 168 hours. To control samples 1 ml of ethanol 96% was added instead of elicitor solution and samples were collected after 24 and 168 hours. Samples were taken at given time intervals and dried. Subsequently, the rutin content was monitored by HPLC. The rutin release into the nutrient medium was also tested. During the experiment on the callus cultures no statistically significant increase in rutin production after elicitor treatment was observed. But elicitor increased rutin production in suspension cultures after treatment in all tested concentrations. The calluses always released rutin into the nutrient medium. The rutin content in the media ranged from 53,4 to...
Analysis of Czech Language Secondary School Text Books from the Gender Point of View
Dvořáková, Jana ; Chejnová, Pavla (advisor) ; Hájková, Eva (referee)
The thesis examines the issue of gender in textbooks. The aim of the thesis is to analyse three sets of Czech language secondary school textbooks and ascertain, whether these textbooks contribute to the propagation of gender stereotypes in the society or whether they do not. The thesis is divided into a theoretical section and an empirical section. The theoretical section firstly explicates the fundamental concepts of gender, secondly focuses on the discrimination of women via language and on other topics from the field of gender linguistics. The last chapter of the theoretical section focuses on how gender stereotypes influence schooling. The empirical section encompasses the aforementioned analysis of the selected Czech language textbook sets. The analysis further investigates the manner in which men and women are represented in the curriculum, how men and women are portrayed in the illustrations, if the linguistic means are gender-balanced, and also whether the textbooks include any gender linguistics topics. The results of the analysis show that in all textbook sets, men are the dominant gender in illustrations, as well as among significant figures and authors of literary excerpts. In terms of roles, employment and character traits that are attached to individual characters, the sets of...

Philosophical aspects of education in dialogue between Wolfgang Brezinka and Zygmunt Bauman
Dvořáková, Jana ; Dolista, Josef (advisor) ; Zátka, Vlastimil (referee)
The text of this work is primarily based on the works of Wolfgang Brezinka, focusing on the philosophy of education and on many sociological works by Zygmunt Bauman, which are cited for better orientation in the philosophical-educational context of the chapter focusing on the philosophy of education used in the antiquity The aim was to present the reader with at least a brief awareness of the individual aspects of the philosophy of education as presented by Brezinka and to supplement it with the possible aspects that can be taken from Bauman, who primarily focuses on exploring the socio-cultural phenomena of the modern society. Gradually, the essential characteristics, features, and characteristics that accompanied the upbringing in antiquity are presented, just as the educational aims and beliefs in relation to the upbringing that is presented by Brezinka. Furthermore, there are discussed and examined the pitfalls of modernism and postmodernism in relation to personality, culture, society and philosophical-educational possibilities as pointed out by Bauman. The amount of works on the philosophy of education is insufficient and even here, of course, it has not been possible to cover all the philosophical aspects of education which are available to the authors dealing with the philosophy of education, yet...
On the analysis of thin-wall parts sawing
Spáčil, Radek ; Dvořáková, Jana (referee) ; Píška, Miroslav (advisor)
Master‘s thesis deals with sawing of the thin-walled parts with high speed steel slitting saw. At first the most used conventional and unconventional possibilities of materiál cutting are described by a form of search. The next chapter describes forces arising from splitting saw machining, including their dependence on a specific cutting force, a chip cross section and a engagement angle. The second part of the thesis deals with the technological improvement of the cutting process, where three possible solutions are considered – geometry of the cutting tool, PVD coating deposition of the cutting tool and process fluid change. In the experimental part non coated slitting saw with burrs, non coated deburred slitting saw and coated slitting saws are compared. Used coatings were Ti(C,N), Cr-Al-Si-N, Al-Cr-B-N, and TripleCoating Cr, which is consisting of three layers TiN + (Al,Ti)N + Cr-Al-Si-N. The experiment has shown that the cutting forces inceases as the edge radius and wear level of the cutting tool increases. Coated cuttung tools has shown lower differences between the first and the last cut. Slitting saws have been also used in real cutting process to verify experimental results.

The de minimis regime and financing of Czech theatres
Jonášová, Helena ; DVOŘÁKOVÁ, Jana (advisor) ; SOUČKOVÁ, Jaroslava (referee)
This diploma master thesis focuses on the de minimis regime and its application within financing of theatres in the Czech Republic. The de minimis regime is one of the instruments of finance regulations of finance from public budgets, in relations to enterprises in the Czech Republic. As it is an instrument of so-called state aid with considerable selective features, is it a subject of thorough regulations by the European Union. These regulations thus directly affect legal systems of member countries of the EU. The aim of the master thesis is to describe how the de minimis regime affects the opportunities of Czech theatres to receive financial support from public budgets and to find out how the legal acts of the European Union affect the financial situation of these theatres. The thesis also deals with the problem as seen from the point of view of providers of these financial supports so that it could be possible to reflect the issue as a whole. The theoretical background of the thesis is formed by the relevant legal acts, issued by the European Commission and by the commentaries made about them. An inseparable part of this work is also grant calls of individual grant providers in the Czech Republic. The practical part of the master thesis is then based on thorough research of all Czech theatres with regards to their relations to de minimis issues. The master thesis also works with data provided by the Czech Register of the de minimis regime.
