Letko, Zdeněk ; Lourenco, Joao (referee) ; Sekanina, Lukáš (referee) ; Vojnar, Tomáš (advisor)
V disertační práci je nejprve uvedena taxonomie chyb v souběžném zpracování dat a přehled technik pro jejich dynamickou detekci. Následně jsou navrženy nové metriky pro měření synchronizace a souběžného chování programů společně s metodologií jejich odvozování. Tyto techniky se zejména uplatní v testování využívajícím techniky prohledávání prostoru a v saturačním testování. Práce dále představuje novou heuristiku vkládání šumu, jejímž cílem je maximalizace proložení instrukcí pozorovaných během testování. Tato heuristika je porovnána s již existujícími heuristikami na několika testech. Výsledky ukazují, že nová heuristika překonává ty existující v určitých případech. Nakonec práce představuje inovativní aplikaci stochastických optimalizačních algoritmů v procesu testování vícevláknových aplikací. Principem metody je hledání vhodných kombinací parametrů testů a metod vkládání šumu. Tato metoda byla prototypově implementována a otestována na množině testovacích příkladů. Výsledky ukazují, že metoda má potenciál vyznamně vylepšit testování vícevláknových programů.

Optimization of network flow monitoring
Žádník, Martin ; Lhotka,, Ladislav (referee) ; Matoušek, Radomil (referee) ; Sekanina, Lukáš (advisor)
The thesis deals with optimization of network flow monitoring. Flow-based network traffic processing, that is, processing packets based on some state information associated to the flows which the packets belong to, is a key enabler for a variety of network services and applications. The number of simultaneous flows increases with the growing number of new services and applications. It has become a challenge to keep a state per each flow in a network device processing high speed traffic. A flow table, a structure with flow states, must be stored in a memory hierarchy. The memory closest to the processing is known as a flow cache. Flow cache management plays an important role in terms of its effective utilization, which affects the performance of the whole system. This thesis focuses on an automated design of cache replacement policy optimized to a deployment on particular networks. A genetic algorithm is proposed to automate this process. The genetic algorithm generates and evaluates evolved replacement policies by a simulation on obtained traffic traces. The proposed algorithm is evaluated by designing replacement policies for two variations of the cache management problem. The first variation is an evolution of the replacement policy with an overall low number of state evictions from the flow cache. The second variation represents an evolution of the replacement policy with a low number of evictions belonging to large flows only. Optimized replacement policies for both variations are found while experimenting with various encoding of the replacement policy and genetic operators. The newly evolved replacement policies achieve better results than other tested policies. The evolved replacement policy lowers the overall amount of evictions by ten percent in comparison with the best compared policy. The evolved replacement policy focusing on large flows lowers the amount of their evictions two times. Moreover, no eviction occurs for most of the large flows (over 90%). The evolved replacement policy offers better resilience against flooding the flow cache with large amount of short flows which are typical side effects of scanning or distributed denial of service activities. An extension of the replacement policy is also proposed. The extension complements the replacement policy with an additional information extracted from packet headers. The results show further decrease in the number of evictions when the extension is used.

Adolescent overweight and obesity
JINDROVÁ, Kateřina
My bachelor´s thesis deal with obesity of adolescents and problems with overweight. These problems are described in details, and after that divided into specific parts. The main goal of my bachelor´s thesis is to chart problems with obesity and overweight in age group from 15 to 18 (adolescents) and primary describe their eating habits and physical activity. Theoretical part is focused on occurrence of overweight and obesity in the Czech Republic and in the world, causes of its origin, risk factors, classification and diagnosis, types, therapy and prevention. This bachelor´s work dealing with rational diet, describing basic principles of healthy catering and explaining right or wrong foodstuffs. I point mainly on prevention of overweight and obesity by healthy eating and physical activity. Methodical part is processed thanks to quantitative research. Data were gained by questionnaires, which were given to high school students (1st - 3rd grade). The research group contains 150 respondents from different schools in České Budějovice and close neighborhood. Final results are written down primary in graphs with commentary and data charts. In case of right use of qualitative research, there were determined two hypotheses. First hypothesis: Overweight and obesity is more occurred at adolescents with wrong eating habits. Second hypothesis: Overweight and obesity is more occurred at adolescents with low physical activity. For developing exploratory part, there was used quantitative research, which was provided by questionnaires given to students of age from 15 to 18. Entire data were processed by the use of program Microsoft Excel, and its calculations and functions. The answers of respondents were registered into database, and, by using specific excel functions, I was able to report data in determined categories. The research was mainly concentrated on physical activity and eating habits. Final results are put into well-arranged graphs, which are always enriched by comments, eventually completed by data tables, and, subsequently, statistically evaluated. In results, there might be seen two main differences between adolescents with standard weight and adolescents with overweight or obesity problems. One of those is irregularity in eating and wrong eating habits; big difference is also proved in physical activity. Adolescents with obesity or overweight have often irregular food intake, they drink a lot of high caloric beverages such as Coca-Cola, Sprite, Fanta etc., deficient income of fruit, vegetables, legumes, fish, or low physical activity. Only few of obese adolescents is different, because their problem is caused genetically. Adolescents with standard weight eat more regularly, but there are also some special cases, who have similarly wrong eating habits as obese people; however, all of these adolescents have one typical quality regular physical activity. Both hypotheses are confirmed. The results show that obesity is mainly caused by genetic predispositions, but these factors can be positively affected by periodic physical activity or appropriate eating habits. At the end of the thesis, it should be mentioned that it is necessary to be focused on right eating habits and regular physical from the very young age, when the basic customs and habits are assumed. That should include parents' action around their children, as they are usually the first example and they have the biggest influence.It is important to develop knowledge about all kinds of prevention, which are in most cases major in defending against formation of overweight and obesity.

The role of a nurse in a prevention and a treatment of intestinal parasites of children
JANDOVÁ, Anna
The best-known intestinal parasites are Pinworms, Roundworms, Tapeworms and the disease called Toxocarosis. The oftenest parasite is, according to sources, the Pinworm. Intestinal parasites affect mostly young children of pre-school age, sometimes even older. The first goal of the thesis was to investigate parents' awareness of the prevention of parasitic diseases in children. There is a hypothesis set to this goal: Parents of children who suffered from parasitic disease are more informed than parents of children who have not had this disease. The second goal was to map the specifics of nursing care for children with parasitic diseases at GPCHA practice. A research question was chosen for this aim: What are the specifics of nursing care at GPCHA in parasitic diseases? In methodology, the empirical part was chosen and it was a qualitative - quantitative research survey. For the quantitative part, the interrogation method and technique of non-standardized questionnaire was used. The research sample of quantitative survey consisted of 223 respondents, it means parents whose child is aged from 0 to 6 years. The questionnaires were distributed on social networking and others in a nursery school in Týn nad Vltavou. At the very beginning, respondents were acquainted with the topic of the thesis. The results of a quantitative survey were processed with the help of a data matrix and were further processed within twenty-arranged bar charts. To verify the hypothesis, we used the Chi- Quadrat test, which in this case is not satisfactory, therefore, there had to be chosen to merge the responses. An interrogation method, technique-depth interview was used in the qualitative part. The research group consisted of five nurses; three nurses working at GPCHA in Týn nad Vltavou and two working at GPCHA in České Budějovice. While processing the interviews, there open coding was used and an analysis of interviews was conducted by using the method of Pencil and Paper Interview. The results of this bachelor thesis will be published in the journal Paediatrics practice.

Oxygen therapy after cardiothoracic surgery from the point of view of nurses and patients
VRCHOTOVÁ, Klára
Cardiac surgeries are very serious surgical procedures with considerable specific features. This bachelor thesis focuses on oxygen therapy from the viewpoints of nurses and patients. Its theoretical part describes physiology of breathing and the oxygen therapy as such. It describes individual sources of oxygen and indications for oxygen administration. It also describes principles to be observed during oxygen administration. Specific aids are used for oxygen administration, particularly oxygen masks or oxygen goggles. Quality pulmonary rehabilitation is also necessary to make oxygen therapy more effective. Pulmonary rehabilitation is particularly important for patients after a cardiac surgery and it should be practiced even before the surgery. This approach is critical because in the post-surgery period the therapy makes it possible for the patient to breathe and to expectorate properly. Pulmonary rehabilitation is practiced with patients by general nurses at the cardio surgery ward, as well as by physiotherapists. There are various techniques available to determine efficiency of oxygen therapy and pulmonary rehabilitation. The techniques may be classified as invasive and non-invasive; the most frequently used non-invasive method is pulse oxymetry and the most frequently used invasive technique is blood collection for ABR. Two objectives were set for the thesis. The first objective was to map knowledge of nurses about how to provide care to patients treated with oxygen therapy. The second objective was to determine how the patients feel after a cardiac surgery. Two hypotheses and two research questions were formulated. The first hypotheses were: Nurses working at the resuscitation care station have more knowledge about oxygen therapy than nurses working at the intermediate care station. The second hypothesis was: Nurses working at the resuscitation care station have more knowledge about pulmonary rehabilitation than nurses working at the intermediate care station. The first research question was: How do the patients feel during oxygen therapy and pulmonary rehabilitation? The second research question was: How are the patients after a cardiac surgery informed about oxygen therapy and pulmonary rehabilitation? In the research part of the bachelor thesis I have used both quantitative and qualitative research methods. Quantitative processing of data was used for questionnaires filled out by nurses working in the hospitals Nemocnice České Budějovice a.s., Nemocnice na Homolce in Prague and in the faculty hospital Královské Vinohrady in Prague. The method was used for evaluation and assessment of knowledge of nurses working at the resuscitation and intermediate care wards. Quantitative methods were used for processing of data obtained through semi-structured interviews with patients after a cardiac surgery. The data were transcribed and coded using a pencil and paper method. The data were categorized based on the identified codes. Two categories were created: oxygen therapy and pulmonary rehabilitation. Each of the categories was further divided into three sub-categories. Two categories were created for the research oxygen therapy and pulmonary therapy. Three sub-categories were subsequently created for the oxygen therapy and the pulmonary therapy. The quantitative research has shown that the knowledge of nurses about oxygen therapy is higher among the nurses working at the resuscitation care ward. However, the situation is different in case of their knowledge about pulmonary rehabilitation. In this case the knowledge of nurses working at the intermediate care ward was higher. The processed data from the qualitative research have shown that patients do have sufficient information about post-surgery oxygen therapy, as well as about pulmonary rehabilitation. For all patients in the post-surgery period after a cardiac surgery the frequency of pulmonary rehabilitation was higher than 1 per day.

Specifics of nursing care in patients after transapical aortic valve implantation.
VOTRUBOVÁ, Nataliya
Transcatheter aortic valve implantation (TAVI) is a new and an attractive method in cardiology and as well as in cardiac surgery. It is constantly evolving method which has been developed as an alternative to standard open surgery, especially in patients with severe symptomatic aortic stenosis with unacceptably high perioperative risk or patients who are not suitable for conventional open heart surgery because of age and comorbidities.A teamwork is very importantfor this new method and approach. The choice for TAVI is discussed by the institutional multidisciplinary heart team, typically consisting of interventional cardiologists, imaging-specialists, cardiac surgeons and anaesthesiologists. The first implant in a human being was performed by Cribierin 2002. In Czech Republic this method was first used in 2008. Transcatheter aortic valve implantation (TAVI) was accepted as a minimally invasive alternative to open surgery. This method does not require the use of cardiopulmonary bypass, and cardiac arrest. Other several benefits includinglower risks of bleeding and stroke events, better wound healing, less pain, as well as more rapid early recovery due to preservation of continuity of the sternumthat result in shorter durations of stay in the hospital, earlier rehabilitation and faster returns to normal life. In the presented work was used a combination of qualitative-quantitative methods of investigation. The data was obtained by using the quantitative research. The main technique was using the questionnaires designed for nurses working at the Department of Cardiac Surgery, Hospital Czech Budejovice, a. s. These results were backed up by the implementation of qualitative research, which investigated the patients and physicians view on monitored issues. Questioning method using a semi structured interview technique was used for qualitative research. The results of the survey were processed using descriptive statistics charts in LibreOffice Calc and using diagrams created in LibreOffice Writer. Qualitative results of the research were transcribed from audio recordings and coded, and the base code was created nine categories of interviews with clients/patients and three categories of interviews with doctors. The aim of this work was to explore the specific problem of nursing care about the clients / patients after transapical aortic valve implantation. On the base of our obtained data it is evident, that the client/patient after TAVI may be positioned sideways, the use of surgical drains are less frequently, so the care about the surgical wounds is simpler, patients report less pain in the surgical wound and postoperative rehabilitation and recovery is shorter. H1 - The nurses take care about the clients/patients after transapical aortic valve implantation in the same way as about the clients/patients after open aortic valve replacement, without realizing the differences between the patients treated with different approaches, was not confirmed. The nurses'sees/reported major differences in invasiveness and extent of providing care, rehabilitation, convalescent, in the duration of the hospitalization and better cosmetic effect. The results of the research can serve as a basis for creating the standards of nursing care or educational material for clients/patients. It is also possible to present the results of this work at a specialized seminar for non medical healthcare workers and results can also increase the quality of nursing care about the clients/patients after transapical aortic valve implantation.
