Preparation of web presentation on fundamental conceptions in computer physics
KŘÍŽOVÁ, Jaroslava
This Bachelor's Thesis has undertaken to acquaint high school students with basic information in the field of computer physics. The work is conceived as a textual overview which does not aspire to provide a specialization base for scientific work, but is primarily aimed at understanding the basic terms. In the introduction, I deal with the definitions of computer physics. The chapter entitled Hardware and Software Devices of Computer Physics begins with a brief description of the architecture of the computer and its historical development. This is followed by the basics of programming with a short overview of programming languages. In the chapter entitled Computer Modelling, I present a brief characteristic of this field and acquaint the reader with the basic terms and techniques of modelling. In the following chapter, the reader is acquainted with the principles associated with hybrid modelling as well as the Monte Carlo method. The fourth chapter is intended to be an interesting demonstration of modern trends in computer modelling. In the last chapters, I deal with the brief characteristic of programs that are most commonly used in the field of computer modelling (MATLAB, Fluent and COMSOL Multiphysics).

The Value of CSR for Czech Consumers
Faradji, Elise ; Štěrbová, Ludmila (advisor) ; Seror, Patricia (referee)
Nowadays consumers purchasing behavior is influenced by new factors such as the social and environmental implication of companies. This is why Corporate Social Responsibility (CSR) is a growing trend which companies need to look after carefully. However implementing an efficient CSR strategy is a complex process for corporations; especially since the core concept of CSR remain quite blurry. The goal of this study is to analyze the perception of consumers towards CSR to find out about the value creation that CSR produce for consumers and its impact on their purchasing behavior. This paper will ultimately help companies to implement their CSR strategy more efficiently. This study aims to contribute by conducting an in-depth analysis of consumers attitudes and behavior towards CSR. If most of researchers are using a quantitative approach this study means to deal with the issue with a qualitative perspective. Indeed twelve semi-structured interviews will support the findings. On top of those practical and physical interviews some theoretical knowledge will be added to the construction of the argument especially to bring a framework that shows the importance of all types of value creation (functional emotional and social). The findings of the thesis emphasize the facts already proven by other researchers; value creation is fundamental to make consumers care about CSR. However the study will show how much skepticism towards CSR can impact negatively consumers purchasing behavior. The research will help companies implementing more successful CSR strategy and develop new solutions to reach customers and influence their purchasing behavior through the creation of value for them.

Diversity in the labor market
Gaydoshikova, Ekaterina ; Dvořák, Marek (advisor)
The aim of the thesis is to evaluate the issue of diversity of the labor market in the Czech Republic on the example of specific organizations, evaluate the implementation of the concept of diversity in the workplace on the basis of selected factors. When analyzing diversity is an emphasis on primary and secondary characters of diversity: age, gender, ethnicity, mental and physical abilities, marital status, religion, work experience. The work consists of two parts, theoretical and practical. The theoretical part defines concepts: diversity, equal opportunities, primary and secondary characters of diversity, acceptance of the importance of diversity as a value. The practical part deals with the implementation of diversity into practice on the basis of the analytical methods (analysis: workforce, documents and research positions) and draft incorporation into relevant strategic processes of the organization.

Evaluation of the effectiveness of teaching vocational subjects depending on physical activity before schooling.
Janošíková, Martina ; Hanušová, Marie (advisor)
The period of transition to secondary school brings substantial changes in the requirements for study obligations, autonomy, communication, expression, or separated from their families in the form of staying at the dormitory. Students enrolled in sport centers, in addition to these changes, still struggling with the responsibilities associated with sport. Because they are students first through fourth grades of secondary schools and secondary vocational schools, an age when image self-I am, what I believe in, arises in interactions with the outside world and their own experience, plays a very important role to influence the environment, educators, teachers and trainers, with which students spend most of their time in practice. This study looks at students comprehensively in terms of personal development as a multifactorial biopsychosocial unit, in terms of cognitive and motivational processes, states and properties from the perspective of social psychology dealing with the interactions, relationships and communication, psychology of individuals within the social group and its importance for the development of the individual . It monitors conditions and educational outcomes in terms of educational psychology, dealing with forming properties, opinions, attitudes and value orientation from the perspective of educational psychology.

Individual human odor as a forensic trail in criminal proceeding made by contact or contactless transmission and its resistance to physical agents
Santariová, Milena ; Bartoš, Luděk (advisor) ; Chmelíková, Eva (referee)
The dissertation thesis consists of four papers that have been published in scientific journals.
Study n. 1
The need to recover evidence from water is quite common in criminal investigation. The article deals with the possibility to collect human scent from such objects and with the ability of specially trained dogs to match such scent samples with scent samples collected from detained suspects. During an experiment, designed as a blind one, it has been proved, that human scent can survive on submerged objects and can be later used for scent identification.
Study n. 2
To collect odors the Czech Republic Police use special fabric sorbents manufactured under the registered mark ARATEX. Before use the fabric sorbent is treated by water vapor sterilization. After the scent identification the sorbent is destroyed. The goal of the study was to verify if the vapor sterilization is effective enough to remove human scent that has already penetrated into the sorbent structure or in other words if the sorbent can be exposed to vapor sterilization and then used again. Specially trained dogs were used to match starting odors with target odors in the line-ups. The results showed that dogs are able to correctly match human odors even after they have being exposed to vapor sterilization.
Study n. 3
The purpose of the study was to determine the temperature at which the human scent is degraded so that a dog would not be able to identify it. In contrast to expectations, eight dogs used in the experiment almost flawlessly identified human scents from five scent donors exposed to temperatures of 100°C, 200°C, 300°C, 400°C, 500°C, 600°C, 700°C, and 800°C. Only two of the dogs were able to identify 5 of 15 scent samples exposed to 900°C. No dog identified a scent exposed to 1000°C. Our study verified heat survivability of human scent far beyond existing expectations.
Study n. 4
We tested the hypothesis that if odor fallout (the release of a human odor onto an untouched object) in human subjects exists, then holding a hand above an absorbent will produce a detectable scent which will be subsequently matched in a detection test by trained dogs. Scents were collected from seven males to sterile cotton absorbent squares. The left hand was used to get the control scent and the right hand served as the target scent. Each experimental subject was sitting and his left hand was laid down on a cotton square for 3 min. The right hand was held 5 cm above another cotton square for 3 min. The scent identification was done by two specially trained police German shepherds. Both dogs performed 14 line-ups and correctly matched the collected scents of all test subjects. The results suggest the existence of human odor fallout, whereby a human scent trace is left by humans even if they do not touch an object.

Total contents and speciation of arsenic and selenium in plants growing in soils with different physico-chemical properties
Tremlová, Jana ; Száková, Jiřina (advisor) ; Vymazal, Jan (referee)
This dissertation thesis deals with uptake, accumulation and transformation of arsenic and selenium in plants growing on soils with different chemico-physical soil properties. The contents of arsenic were investigated in 99 wild plant species, coming from 27 different families and 6 different vegetables growing in arsenic contaminated soils. The results suggest that there are species-specific mechanisms which protects certain plants from the excessive uptake of arsenic from the soil. On the other hand, there are plants using a strategy of accumulation, which theoretically may increase the risk of arsenic entry into the food chain, whether through grazing cattle and wildlife or through consumption of vegetables growing on arsenic contaminated soils. The most prevalent arsenic compounds are AsV and AsIII. Other arsenic compounds occure as minor species. An important finding was detection of arsenobetaine in Plantago lanceolata L. and Carex praecox Schreb ..
The contents of selenium were examined in 73 species of wild plants, coming from 29 different families. The results suggest that naturally low levels of selenium in the soil of selected locations along with a low capability of selenium uptake via collected plant species lead to the low content of selenium in plant biomass which may contribute to selenium deficient throughout the food chain. Foliar application of selenate on wild plant communities and on some types of vegetables in our case Brassica oleracea var. italica can have a positive impact on increasing the selenium content in the aboveground biomass of these plants and by extension, increase the selenium content in the human diet. Dominant selenium compounds in the aboveground biomass of the analyzed plants were SeVI and selenomethionine, with variable proportion of other commonly occurring organic selenium compounds, which is mainly affected by plant species.

THE DRAMATICAL SCRIPT AS A NECESSARY BASIS FOR SPACIAL REALIZATOIN
Tretiag, Štěpán ; KORČÁK, Jakub (advisor) ; HRBEK, Daniel (referee)
Using the concrete examples of my practical bachelor work my intent is to retrospectively describe and reflect on our scenic realization of the play Missing by south-African author Reza de Wet. The essence of a modern dramatic direction is to perceive the script of a play as a model which becomes a basis for its interpretation and the subsequent staging of the play. It is the process from the initial interpretation to final scenic realization I wish to focus on in my work.In the first part I will be dealing with creation of a physical space, that being stage design. I will try to capture what lead us to its final shape and how the basis for that can be found in the script of the play as well as the potential capability of the physical space to become a dramatic space. Its ability to create a platform for the actors to proceed from and how can it provoke them into acting, in particular. In the second part I will be dealing with the dramatic space, ergo the spacial expression of relationships and themes. I will proceed again retrospectively, focusing on how we managed to achieve the stage image which is functioning as a materialized metaphor. I will focus mostly on non-verbal actions, but with regard to the fact, that dramatical script is the basis for our realization of the play.
