Methodology of highly reliable systems design
Straka, Martin ; Gramatová, Elena (referee) ; Racek, Stanislav (referee) ; Kotásek, Zdeněk (advisor)
In the thesis, a methodology alternative to existing methods of digital systems design with increased dependability implemented into FPGA is presented, new features which can be used in the implementation and testing of these systems are demonstrated. The research is based on the use of FPGA partial dynamic reconfiguration for the design of fault tolerant systems. In these applications, the partial dynamic reconfiguration can be used as a mechanism to correct the fault and recover the system after the fault occurrence. First, the general principles of diagnostics, testing and digital systems dependability are presented including a brief description of FPGA components and their architectures. Next, a survey of currently used methods and techniques used for the design and implementation of fault tolerant systems into FPGA is described, especially the methods used for fault detection and localization, their correction, together with the principles of evaluating fault tolerant systems design quality. The most important part of the thesis is seen in the description of the design methodology, implementation and testing of fault tolerant systems implemented into FPGAs which uses SRAMs as the configuration memory. First, the methodology of developing and automated checker components design for digital systems and communication protocols is presented. Then, a reference architecture of a dependable system implemented into FPGA is demonstrated including several fault tolerant architectures based on the use of partial dynamic reconfiguration as the mechanism of fault correction and the recovery from it. The principles of controlling the reconfiguration process are described together with the description of the test platform which allows to test and verify the design of fault tolerant systems based on the methodology presented in the thesis. The experimental results and the contribution of the thesis are discussed in the conclusions.

Network Architecture and Interconnection of Embedded Systems
Trchalík, Roman ; Drábek, Vladimír (referee) ; Srovnal, Vilém (referee) ; Švéda, Miroslav (advisor)
The thesis focuses on the architecture of embedded systems. It summarizes the current state of accepted standards from IEEE 1451 family, which deals with creating an environment for the sensors and their involvement in various networks. These standards describe the open, network-independent communication architecture for a sensor-based system. One of the main outcomes of this work is the architectures presented as case studies, which can be used as design patters for embedded applications. They are demonstrated on ZigBee technology suitable mainly for small devices with very low power consumption. Based on these studies the new design of universal gateway was proposed. Its major advantage is that it allows interconnection of the endpoints based on different sensor network technologies. Additionally, the thesis deals with modifying the routing protocol of ZigBee network in order to reduce power consumption required to transmit one data packet.

Composing Data-driven Circuits Using Handshake in the Clock-Synchronous Domain
Sýkora, Jaroslav
We present a technique for modelling and synthesis of fine-grained data-driven circuits in the clock-synchronous hardware, such as the field programmable gate arrays (FPGA), called the Flow-Transfer Level (FTL). The distinguishing property of the FTL technique is that it does not rely on FIFO queues to handle flow synchronization between the components (called operators). The communication channels, called pipes, employ conceptually a two-state handshake protocol. The handshake behaviour of each operator is defined logically using dependency subgraphs that are symmetrical for producers and consumers. The original data-flow netlist of operators is transformed into a global control dependency graph. Cycles in dependency graphs are allowed as long as they do not constitute real data dependencies but only dependencies in promises of handshake completions. A method is given that recursively eliminates these cycles.

The reflection of František Bakule's work in a relation to a current special educational practice
BALÍKOVÁ, Tereza
František Bakule was a significant Czech teacher during the first half of the 20th century. He was known as the first director of the "Jedlicka Institute in Prague" as well as the founder of so-called "Bakule´s Institute" as well as one of the few representatives of the "Czech alternative approach towards education" which is very well recognized all around the world. His legacy and teachings, however, are currently not being developed on the systematic level and neither they are being put into practise by Czech professional mainstream educational community. We also need to mention that is not used by even the stream of special education, in contrast to many foreign alternative pedagogical trends, which are gaining popularity and are generally applied with success. The aim of this thesis is therefore to analyse the work of Frantisek Bakule through the prism of contemporary school educational environment with emphasis on the education of students with disabilities. The first chapter is devoted to outlining the life journey of Frantisek Bakule, particularly focusing on the major milestones that influenced the formation of his personality, his ideas, inspiration and motivation which was reflected in his teachings and then in his very own coherent concept of education. To be specific, we are introduced to his family background and a significant part is then devoted to description of Frantisek´s experience as a teacher, including stages of operating in Jedlicka´s Institute and in his own "Bakule´s institute". The second part is then focused solely on Bakule´s specific educational concept. First, the core principles of the concept are defined. Later parts then talk about Bakule´s original curriculum and a his proposal of an ideal classroom environment. The text also contains a detailed description of how Bakule approached several subjects, which were at the core of his teaching concept, namely "Work activities", "Music education" and "Arts". Original teaching practices are analysed by using current teaching methodology and terminology. Due to the identified aim and goals of the thesis, the third chapter analyses the current concept of education of the above, according to Bakule´s core areas and principles. The text is designed specifically to be subsequently reflecting the work of Frantisek Bakule from the perspective of today's teaching methods, namely the methods of special education. The idea is to define common points and possible differences and uncover hidden inspirational potential, which is then the main content of the fourth and final chapter. Based on the analysis and all its subsequent reflections, the final chapter tells us that although Bakule´s educational goals don´t differ too significantly from the current concept embedded in the relevant framework of educational programs, to achieve such goals we are currently using very different techniques and methods in comparison to Bakule´s ways. Even though Bakule himself tested and verified all of his concepts in practice, which can be very simply described as "do not teach students about life and work, but through life and work", and these concepts also have been proven correct by various subsequent results of psychological researches, the current system still doesn´t draw from them too much. From all the above it is quite obvious that the legacy of life´s work of Frantisek Bakule is currently not utilized nor it is being appreciated by our professional pedagogical community. On the other hand, we need to note that it may also be due to the level of fragmentation in which his concept and materials were preserved to the present days.

Communication of medics with the parents of a child patient.
ŽÁKOVÁ, Nikola
The theoretical part is divided into eleven chapters. The first chapter deals with the definition of communication. The second chapter describes the kinds of communication, including verbal and nonverbal. The third chapter discusses the communication skills of nurses. In the fourth chapter we expanded on the communication of the nurse with a child patient. The fifth chapter describes the basics of communication between nurses and parents of child patients. The sixth chapter discusses a situation where the nurse communicates with parents of a disabled and dying child. The seventh chapter describes the communication of nurses at the pediatric department. The eighth chapter contains the specifics of the children's department. In the ninth chapter is divided into childage. The tenth chapter discusses communication as a part of nursing care. A final chapter describes the process of hospitalization of children and their parents. The thesis is divided into theoretical and empirical parts. Much of the theory is described above whereas the empirical section describes the results of the research. Objectives and research questions The first objective of this thesis was to investigate how the nurse communicates with the parents of a child patient. The second objective was to determine whether a parent understands the information given by the sister and the final objective was to determine any errors that the nurse makes when they communicate with parents of child patients. Research questions: 1. How the nurse communicates with the parent of a child patient? 2. How does the nurse inform parents of a child patient? 3. How a parent of a child patient assesses the clarity of the information provided by the nurse? 4. What mistakes nurse makes in communication with the parents of a child patient? Methodics For the research a survey was chosen to provide qualitative information, which was obtained via interviews. The second methodology used in this work is called participant observation. Data for the first part of the survey was obtained through semi-structured interviews with the parents of hospitalized children. Interviews were conducted on the basis of questions prepared in advance. If necessary, the interview was supplemented with other issues. The interview was to determine how children were admitted to the children's department, what information reached parents about the examination of the child, and also the overall impression of the nurses on the ward. We asked parents about the verbal and nonverbal communication of sisters. They described the errors they found in the communication and behavior of nurses. The second part of the research was anonymous on the pediatric ward of the hospital where nurses evaluated verbal and nonverbal communication skills. The research group The research set for the first part of the survey consisted of seven mothers of children hospitalized in the pediatric ward. The mothers were in different hospitals in the Czech Republic. The research set for the second part of the investigation, which was carried out by observation technique, consists of six nurses employed at the pediatric ward of a state hospital. Nurses were selected randomly. They are of different ages and they have different length of practice and other training.

Practical use of theatroterapy in the activation process of adults with intellectual disability
REJŠKOVÁ, Denisa
The aim of my bachelor thesis "A Practical Usage of Theatrotherapy During a Stimulation of Adult People with Mental Handicap" was to create, execute and evaluate a theatre performance focusing on a stimulation of mentally disabled adults. During leisure activities, it is possible to offer to mentally disabled people such activities that develop their personalities universally, lead towards their own activity and creativity. However, the mentally disabled people´s selection of activities is limited in comparison with the intact ones. Considering an offer of leisure activities for the target group, I decided to use theatrotherapy which has been created for them and then to implement a theatre performance. According to the specialised literature, by using it, it is possible to reach positive results in the field of communicative and locomotive skills as well as the memory and social relations. This thesis consists of three chapters. The target group will be defined in the first chapter in which I define the term of mental disability, characterise adult people with medium or severe mental disability and specify their social, mental and locomotive limitations in details. I define the theatrotherapy, describe its development, aims and methods in the second chapter. Simultaneously I mention it as a means of stimulation in the conclusion of this chapter. Theoretical part of the work is followed by in the third, practical chapter. I prepare a theatre performance based on specialised literature which I implement and evaluate here. The theatre performance was based on principles and rules of theatrotherapy. An original script adapted to the target group was used for its implementation. Classical teaching methods and drama teaching methods were used for rehearsing, namely methods verbal, graphically demonstrative, practical skills gaining, roleplaying, methods and techiques of training games and exercises, evaluation and reflection. During the evaluation and objective technique was used which aims for an analysis of actor´s activity, and a subjestive technique which aims for self-evaluation and actor´s feedback. The above mentioned activity was supported by IN Civic Society and ten people with medium and severe mental disability aged 25-45 participated. There was a process of involvement during a making of the performance and positive results in the field of communicative and locomotive skills were reached. The actors experienced new and unusual situation during the performance. They met new people too because some students of the University participated too. This resulted in social integration. The bachelor thesis is meant as an inspiration for the personnel of institutions providing social services.

The role of nurses and their impact on the care of patients with total hip arthroplasty.
SLABÁKOVÁ, Květoslava
Total hip replacement is one of the most extensively and highly effective operating methods in orthopaedics. The patients are brought back the self-sufficiency, life without the pain and noticeably motion restriction. Irreplaceable function here is a role of the nurse, who helps the patient to return back to his common life...The aim of this work was to find out, how the patients feel the role of the nurse and its influence to given nursing care before and after the total hip replacement as the less fulfilled. There were following research questions set: How the patients feel the role of the nurse before and after the total hip replacement? How the patients before and after the total hip replacement feel the interpretation of the nurse roles? How the patients before and after the total hip replacement feel the role of the nurse and its influence to given nursing care. Which of the nurse roles are felt by the patient as the unsatisfactory in postoperative care? The patients before and after the total hip replacement feel through the everyday nurse activities the nurse in her role of the caregiver and education giving person, following the nurse vindicator and the nurse bearer of changes. The patients feel the care thanks these roles as a quality, holistic and continual. Nevertheless was the role of the education giving named as the least fulfilled. In connection with these research results was created a manual, a Guide book for the patients before and after the total hip replacement. This Guide book was given to testing purposes. This Guide book was appreciated by the patients very positive despite a large amount of information, which were surprising for many of them. We gained some data, which gave the impulse to complete the information in the Guide.The created Guide book can´t replace the effective communication of the patient with the medical staff, which could be always the most suitable "source" of information.
