Šubčíková, Lenka ; Martínková, Markéta (advisor) ; Milichovský, Jan (referee)
Chronic pancreatitis is complex disease with complicated diagnosis. Nowadays there are the diagnosis and classification of chronic pancreatitis primarily based on imaging methods. In this study the results of two indirect tests of pancreatic exocrine function with different arrangement were compared. The pancreatic fecal elastase 1 was determinate by immunoassay with monoclonal antibody, as a simple screening test. The dynamics and kinetics of pancreatic exocrine secretion was observed by a breath test with 13 C-labeled substrate. The group of four volunteers was monitored for six months and analyzed each month. The mutual variability of these tests and their correlation was studied. The patients' (suspected suffering by chronic pancreatitis) anonymous data for these tests created by the Institute of laboratory biochemistry and laboratory diagnostics between 1999-2012 were statistical processed. We found, that the indirect tests of pancreatic exocrine function and determination of pancreatic enzymes does not correlate. Both of these tests have the specific diagnostic value mainly for diagnosis of pancreatic exocrine insufficiency. 1

Jůnová, Štěpánka ; Kera, Denisa (advisor) ; Koťa, Jaroslav (referee)
The thesis consists of current and traditional language teaching methods' description. Methodical approaches for language teaching in virtual reality are also described. One example of applying methodical approaches is mentioned in connection with effectivity evalutation. A project and a case study is a part of this thesis. They focus on application of different language teaching methods in Second Life. A combination of pedagogical research methods was used to carry out the project. Two goals were set in the project. The first goal was about to find out the average knowledge the students acquired depending on applied teaching method. The second goal was about to find out the average knowledge the students acquired in total. The indirect and mixed teaching methods proved as the best in the research. In the section "Project Realization" there is a final report about useful findings and recommendations for effective use of Second Life in the field of education. A video domumentation from the research can be found on enclosed CD. During the research that was originally defined by the university a new questions and problems appeared like Netspeak and language learning, question of identity when applying for a job in Second Life or how to document your teaching activities in virtual environment with the help of...

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.

This diploma thesis deals with the problems associated with acquisition of experimental data from technological unit for biomass combustion with nominal capacity of 1 MW, with regard to determination of thermal efficiency. In the introduction part, parameters of currently available biomass-based fuels as well as of those with large potential in the future are summarized. Further, a review in the field of biomass combustion technology is given. Biomass boilers are compared according to their technical parameters, function and benefits and drawbacks. In theoretical part methods for determination of thermal efficiency by direct method, indirect method and modified indirect method are described. Main parameters influencing resultant values of efficiency are included into the analysis. In final part an evaluation of real operational data from prototype unit combusting wooden chips is made. Recommendations for further experimental data gathering and their processing with the aim to evaluate thermal efficiency are suggested.



Prediction of Stock Returns Usig Financial Statement Analysis
Hájková, Petra ; Jakubík, Petr (advisor) ; Hollmannová, Monika (referee)
This diploma thesis should contribute to research in the area of fundamental analysis. Its aim is to study whether financial statement data of Czech non-financial companies capture information that is not reflected in prices. Therefore, the question is whether investment strategy based on financial statement analysis could earn excess returns. In order to test this hypothesis, a three-step estimation procedure based on a logit model is used to identify financial ratios relevant for prediction of future earnings. The final estimated model includes four financial ratios and is then used to set a one-year investment strategy. Although the performance of the estimated model is not too sound, this investment strategy brings positive abnormal returns during the monitored period of time. Despite the fact that results were influenced by several factors, they could indicate that financial statement analysis of companies listed on the Prague Stock Exchange is able to predict stock returns.
