Statistical investigation of CT pulmonary angiography in terms of development and depending on age and sex in District Kroměříž 2006-2010
OPLUŠTIL, Vladimír
CT pulmonary angiography is, together with ventilation-perfusion scintigraphy, the main diagnostic methods for recognition as pulmonary embolism. This is a very dangerous disease, which may end up even in death. Its share of deaths in hospitals, including subsequent ? complications, is around 4%. Therefore, emphasis is placed on early diagnosis. Clinical and laboratory symptoms are unspecific (including D Dimer).(10) Pulmonary embolism after ischaemic heart disease and arterial hypertension the frequency of its occurrence, the third most serious cardiovascular diseases. Cause of death in pulmonary embolism is usually the exhaustion of the right heart, seeking to overcome suddenly increased the resistance of the pulmonary circulation. This is the pulmonary artery or its branches is embolism blood clot-trombus, resulting in the venous system or in the heart, a saddle embolus, patched up a significant part of the lung. The most common place of trombs, which embolizated to the lungs, are deep veins of lower limbs if they are affected by the flebotrombolitis.(16) In addition to the acute embolism are frequent and chronic embolism. They are equally dangerous. By gradually and subtly clog small blood vessels, reduces the total cross-sectional area of open pulmonary artery, which have blood flow, and since the volume of blood must be maintained even in the smaller section of the vascular bed, should permanently increase the blood pressure in a small circulation, which is also dangerous.(16) In my work is the methods of mathematical statistics processed file 1966 CT pulmonary angiogramy (CTPA), carried out on the CT work in Kroměříž in the years 2006-2010. The work is focused on the statistical survey of the influence of age, sex, and the time evolution of the CTPA during that period.

Comparison of knowledge of the general and professional public about the IRS
VINCÍK, Miroslav
To meet the objectives set by the thesis it was needed to carry out structural analysis of the Integrated Rescue System. Based on this analysis, statistical survey using descriptive methods and mathematical statistics was conducted. Statistical survey is based on the results of the questionnaire survey carried out in two groups of respondents from both the general and professional public. The respondents were chosen as a representative sample of citizens of the district Strakonice, which was specified in a separate chapter. The presence of the normal distribution of knowledge in the general public was then verified, on the contrary, in the professional public the presence of Poisson distribution was surveyed. The difference in the level of knowledge between the two groups of respondents was determined. To achieve the set objectives of the research three hypotheses were established: H1. The empirical distribution of knowledge of the general public can be replaced by the normal distribution at the level of mathematical statistics. H2. The empirical distribution of knowledge of the professional public is more remote to the normal distribution due to a higher level of knowledge. H3. There is a statistically significant difference between the knowledge of both groups of respondents. All 3 hypotheses were verified and accepted, with a positive result confirming the established hypotheses. In the "Discussion", analysis of the obtained results and confirmation of the established hypotheses H1, H2 and H3, together with proposed measures that could increase knowledge of the IRS in both groups of respondents, is presented.
