Stiff Systems Analysis
Šátek, Václav ; Dalík, Josef (referee) ; Horová, Ivana (referee) ; Kunovský, Jiří (advisor)
The solving of stiff systems is still a contemporary sophisticated problem. The basic problem is the absence of precise definition of stiff systems. A question is also how to detect the stiffness in a given system of differential equations. Implicit numerical methods are commonly used for solving stiff systems. The stability domains of these methods are relatively large but the order of them is low. The thesis deals with numerical solution of ordinary differential equations, especially numerical calculations using Taylor series methods. The source of stiffness is analyzed and the possibility how to reduce stiffness in systems of ordinary differential equations (ODEs) is introduced. The possibility of detection stiff systems using explicit Taylor series terms is analyzed. The stability domains of explicit and implicit Taylor series are presented. The solutions of stiff systems using implicit Taylor series method are presented in many examples. The multiple arithmetic must be used in many cases. The new suitable parallel algorithm based on implicit Taylor series method with recurrent calculation of Taylor series terms and Newton iteration method (ITMRN) is proposed.

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.

Effect of a graduate of field of study Special Education - tutorship in practice of providers of social care
SALABOVÁ, Jana
Theoretical part of the thesis is divided into 4 main chapters. First one deals with the helping professions generally, their definitions and definition of the Special education - Tutorship branch of study per se.It also briefly touches the subject of readiness of the future graduates to deal effectivelly with the challenges of a career in the field of social services. Chapter number two is called Special education and it defines the subject of special education itself, it's purpose and inner structure. Third chapter focuses on social services. It brings up it's definition and types and forms of social services.It also contains the examples of the institutions which fall into this category and it's providers. Chapter number four, which happens to be the last one in the theoretical part of the thesis, covers the role and purpose of graduates of the special education - tutorship studies. It brings up the definition of a social worker, necessary prerequisites as well as beneficial personality traits and feautures. In a subchapter of chapter four is a short description of a pedagogue tutor. Definition who he actually is, who are proper candidates for this position, what are desired personality traits we look for in tutors and the actual content and purpose of their work in institutions providing social services. The end of chapter four is dedicated to a position of a social worker. His activities, the position and definition of a personal assistant and again personality traits needed for a successful career in this field. The objective of the practical part of the thesis is to describe working of Special education - tutorship studies graduates in practice. Particularly their experiences "from the field", how do they evaluate the level of skill of fresh graduates during their first encounters with the reality, how satisfied are they with their choice of a career so far and what was their motivation to pursue such career. Practical part of the thesis includes qualitative research. To meet the above objectives, data collection technique had been chosen using a structured interview with the respondents, who were graduates of Special education tutorship studies. You can tell by the results of this thesis that graduates in the field of social services apply mostly to lower positions as a social service workers, even though they are qualified to perform as a social workers. The age of clients with whom the respondents work ranges from childhood to senior. The motivation that led those questioned respondents to the decision to choose the area of social services varies. Some reported that they were influenced by the actual practical experience during their studies at the university, when both the work itself and their enthusiasm for the target group played role. Others expressed they had previous experience working with people with disabilities or they just wanted to acquire new experiences. Also, involvement of a family member and their previous education was a motivation. Job satisfaction is evident from observed data, and it also contributes to work done accurately and responsibly. Personal benefits for the respondents according to findings are usually their usefulness at work, new experiences they are getting and last but not least advances of their clients. As the biggest advantage the respondents usually mention variability of their work, target group and the clients in itself and the fact, that their work is highly satisfying and they basically work in a very pleasant team of individuals. On the other hand, not exactly satisfying financial reward and challenging working hours are mentioned as disadvantages. Special education - tutorship studies - the branch they've studied, is by the majority of respondents considered to be beneficial for them and they especially highlight practical impact of practice they completed during their studies and which included visits to various relevant institutions.

The need for security and safety in connection with a planned surgery with the patient's perspective and nurses
BOHDALOVÁ, Jaroslava
A planned operation performance always affects patient´s needs for assurance and safety. It is important to provide necessary information connected with the planned operation performance itself so that the patient can feel assure and safe. The key role for the patient and her/his needs for assurance and safety is in general nurse´s hands because she is the closest person to the patient and can help to inspire her/his needs for assurance and safety with konfidence best through the aid of her knowledge and skills that she should have as well as through the aid of her attitudes. The target of the thesis was to find out how a planned operation performance affects patient´s needs for assurance and safety and how a general nurse inspires patient´s needs for assurance and safety connected with a planned operation performance with confidence. The following research questions were stated: How does a planned operation performance affect patient´s needs for assurance and safety? How does a general nurse affect patient´s needs for assurance and safety connected with a planned operation performance to inspire her/him with confidence? What is insufficient in filling patient´s needs for assurance and safety before a planned operation performance? How can a general nurse help a patient control her/his fear and state of anxiety related to a planned operation performance? The method qualitative research with the use of depth interview was used to figure out the investigation. The respondents were willing to record the interview which were verbally rewritten and then subjected to the contents analysis by the method paper and pencil. From the research it is clear that a planned operation performance affects patient´s needs for assurance and safety in a negative way disregarding to her/his previous experience. Patient´s worries and negative feelings can be eliminated by a general nurse who treats her/him as equal, taking up an individual approach, informing her/him about all performances and proceedings, having a calming and welcoming way of communication, using empathy and listening as well as trying to meet patient´s wishes according to her possibilities. The research reveals the advantage of patients´ readiness for planned operation performances. Patients can learn it in the framework of educational proceeding in the out-patients´ department at the same time when they learn that they are going to be operated. The research also shows that general nurses do not have enough knowledge in the sphere of therapeutical communication. The results indicate that it would be suitable to start educating patients as soon as it is known how their disease will be solved and treated in order to reduce the negative impact of surgical treatment to patients´ needs for assurance and safety. General nurses should complete their knowledge and skills to be able to help patients to cope with their difficult life-situation. On the basis of the research investigation and after the consultation with the senior nursing officer, the training course will be organized. The topic of the training course will concentrate on communication with patients before planned operation performances with a view to therapeutical communications and therapeutical interviews. Other discovered facts, for example, the lack of information provided to patients and possibilities regarding better patients´ readiness for planned operation performances will surely be solved by the hospital management.

Účinky xenobiotik na oxidační stres, metabolizmus lipidů, integritu DNA a životaschopnost lidských buněk a rybích spermií in vitro
LINHARTOVÁ, Pavla
Pollution of the aquatic environment by inorganic and organic chemicals is a major factor posing a serious threat to the survival of aquatic organisms including fish. In addition balancing risks and benefits of fish consumption is nowadays an intensively discussed public health topic. Spermatozoa of almost all fish species are released into water environment where they can be directly exposed to various compounds, such as xenobiotics including toxic metals, prior to fertilization. In addition, exposure of parental adults to various xenobiotics may affect gamete quality, which may subsequently reduce fertilization success. On the other hand the advantages of eating fish are well-known, not only in the point that fish is a healthy source of protein and other nutrients, but eating contaminated fish may also confer various health benefits. Research over the past few decades has shown that the nutrients and particularly the n-3 fatty acids (FA) found in fish and seafood, are for examples protective against cardiac diseases and have a positive impact on brain development. The thesis provides a focus on two different cell model types. Firstly, human hepatocellular cells (Hep G2, ATCC) were used as in vitro tool for studying the effect of the intake of cadmium (Cd2+) contaminated fish on cytotoxicity, oxidative stress and fatty acid and phospholipid class compositions. Secondly, spermatozoa of one threatened species of fish, sterlet (Acipenser ruthenus) were used as in vitro model for studying effect of potentially hazardous xenobiotic compounds' occurring in open waters. Sperm from sterlet were exposed for 2h to environmentally relevant concentrations of DQ (0-150

Social perception of Game Management with emphasis on social group dealing with ornithology
Menclová, Barbora ; Obleser, Petr (advisor) ; Adámková, Jana (referee)
This bachelor thesis is focused on evaluation of the stand of ornithological comunity on game management under the terms of problematical relationships between these two groups. Its goal is to chart the concrete fields of arguments within the legislation, as well as game management´s beneficial effects and moral aspects. Another pursuit is also to sketch the realization of possible cooperation. Using questionnaire, which was sent to members of Czech Society for Ornithology and its regional subdivisions, the respondents answered 20 questions and these results were statistically evaluated.
The results show, that game management itself is perceived slightly differently compared with perception of individual hunters. The game management is evaluated more as salutary, whereas the hunters evoke rather negative feelings among respondents. It can be caused by subjective experiences, which influence the way the respondents see the whole game management society. Legislation seems to be the often repeated problem, to be concrete its breaking for example by illegal hunting or insufficient demands for to get a hunting and a gun licence. Ornithologists would also welcome changes regarding the list of the game animals. Problem is also the insufficient knowledge of hunters in the field of ornithology and ekology, which could be solved by tightening the conditions for the hunting and the gun licence.
From the proposals, which were laid in the questionnairy and which are dealing with improving of the mutual relations, the respondents voted mainly discussion - collective, regular, at the expert level, where could be possible to solve actual issues relating game management, as well as ornithology.

Tool to assess the landscape connectivity in different area units and dispersal distances
Chrumko, Adam ; Šímová, Petra (advisor) ; Krčílková, Šárka (referee)
The purpose of this diploma thesis is to introduce a basic summary of landscape connectivity calculations mainly focusing on the Conefor program and the effect of input parameters on output landscape connectivity indices. One of the main goals is to create an ArcMap Toolbox to simplify the calculation of landscape connectivity indices for many areas of interest. Basic squares that cover the whole Czech Republic were chosen as main areas of interest. These units are used for example for mapping the abundance of flora and fauna. The same indices were calculated for NUTS3 and LAU1 areas in order to compare effect of size of input areas. This thesis provides a simple solution in the form of a Python Toolbox for Esri ArcMap to calculate overall indices of landscape connectivity through a Conefor command line application for a large number of input areas. Forest connectivity for different dispersal distances and input areas of interest was calculated with this Toolbox. As an input vector layer of forests, CORINE land cover data from mapping period 1990, 2000, 2006 and 2012 were used. Input dispersal distances were chosen in the range from 50 to 50.000 meters in order to comprehensively describe their effects on indices. Resultant forest and connectivity changes are represented by cartograms; the effect of input data on output indices is shown in graphs.
