Examination and imaging procedures in pneumology from the point of view of a radiographer
VÁVROVÁ, Hedvika
The Bachelor thesis discusses whether SARS-CoV-2 significantly affected the number of lung X-ray and CT scans. The aims of this thesis were "Statistical processing of lung X-ray and CT lung examination data in the X-ray department of the Hospital České Budějovice, a.s. in terms of time distribution over a period of 5 years." and "Analysis of examination and imaging methods in pneumology." In the theoretical part, an overview of the anatomy of the respiratory system was given. Furthermore, SARS-CoV-2 and its effect on the lungs were described. Finally, examination and imaging techniques in pneumology were explained. When the anatomy of the respiratory system was compared with the examination and imaging procedures, objective 2 was found to have been met. The aim of the research part was the statistical processing of the data of lung X-ray scans and lung CT examinations in the X-ray department of the Hospital České Budějovice, a.s. over a period of 5 years. Also, the research focused on an analysis of examination and imaging methods in pneumology. There were three initial hypotheses as follows: "Monthly numbers of X-ray examinations will have a theoretical distribution close to the normal distribution", "Monthly numbers of CT examinations will have a theoretical distribution close to the normal distribution", "Monthly numbers of X-ray and CT examinations are positively correlated". Statistical investigation was used to confirm or refute the stated hypotheses using basic methods of descriptive and mathematical statistics. Based on the results, hypotheses H1 and H2 were confirmed, while hypothesis H3 can be confirmed with time. As a result, objective 1 can be considered fulfilled. The insights gained from this work may be of assistance to follow-up studies. Further research could investigate SARS-CoV-2 and its impact on lung imaging and testing in 2021 and 2022. X-ray and CT scans of the lung in these years would likely fail to test for normality.

Statistical investigation of selected emergency call parameters
VLKOVÁ, Kristýna
The diploma thesis is focused on the activity of the EMS dispatch centre of the Emergency Medical Service, which represents an element of critical infrastructure and is also a part of the Integrated Rescue System. This work deals with the functioning of the Medical Rescue Service, its structure, legislation, crisis preparedness, cooperation with other members of the Integrated Rescue System in case of emergencies and crisis situations. In the research section, a statistical survey of measured data of selected parameters (causes, degrees of urgency) of 155 emergency line calls of the relevant region was used along with logical and empirical methods of applied quantitative research, Hypotheses about normality of the selected parameters were confirmed. Hypothesis about the correlation dependence of the selected parameters was rejected. During the survey, the most common acute problems of callers were identified. Calls were stratified according to the degrese of their urgency according to the valid legislativ. The results of this work can be used to raise awareness of the general population in this field. At the same time the collected data can provide a platform for further research.

Comparison of knowledge of the lay and professional public about the acitivities of the Police of the Czech Republic within the Integrated Rescue Systém
MÁCHOVÁ, Nikola
The diploma thesis as a report on applied quantitative research met a global goal and three sub-goals. The global goal (system analysis of the role of the police of the Czech Republic in the Integrated Rescue System and the definition of internal structural levels characterizing the police of the Czech Republic) was met in the theoretical part. The global goal of the research led to the construction of questionnaires reflecting the basic parameters of the initial theory (theory of civil protection) in the field of activity of the Police of the Czech Republic and generated three partial goals. These sub-objectives were associated with the verification of operationalized hypotheses H1, H2, H3. H1: The empirical distribution of lay knowledge about the activities of the Police of the Czech Repulic in the selected region is close to the normal distribution. H2: Empirical distribution of experts' knowledge of the activities of the Police of the Czech Republic in the selected region is a distant distribution to the normal. H3: The knowledge of lay people and experts about the activities of the Police of the Czech Republic within the Integrated Rescue System is different at the selected level of statistical significance. Hypothesis H1 and H2 were verified using descriptive and mathematical statistics. Hypothesis H3 was verified using methods of mathematical statistics. The system analysis method was used to meet the global goal. One-dimensional and two-dimensional statistical analysis methods were used to meet the sub-objectives and thus to confirm the hypothesis. The benefits of the work include practical and theoretical benefits. Theoretical benefits include confirmation of the applicability of two-dimensional and one-dimensional statistical analyzes associated with the study of research variables "Knowledge of lay people", "Knowledge of experts", "Types of theoretical distributions". Practical benefits include the normality of knowledge among the generel public and the declared distance from normality among experts. The question is whether the observed distance of normality in experts is large enough or should be even higher. It is the examination of the determined distance of normality in experts could be the task of follow-up work. It would also be good to focus on analyzing the results of the answers to the individual questions of the questionnaire. Any identified deficiencies could be reflected in strengthening the training of experts in the identified areas.

Statistical investigation of chosen parameters estate criminality within Police department in Czech Republic
DVOŘÁK, Tomáš
Property crime is one of the most common type of crime. Prime goal of this diploma thesis is to help the structural form of Czech Police by analyzing property crime and its clarification. Regarding to it, the structural form of Czech Police was introduced with the placement of property crime at the whole crime scene in Czech republic. Structural levels this diploma thesis contained: Czech Police (CP), Structure of CP, Main tasks of CP, Connection between executive power and judical power, Prosecution, Ethical code of CP, Crime. Structure level of "Crime" contained: Crime clarification, Factual and place juristiction, Crime control, Property crime (PC), Development of PC, Causes of PC, Legislation of PC, Delimitation of PC, Clarifitacion of PC, Comparing PC to neigboring countries. Partial goal of this diploma thesis was researching the mentioned structural form of Czech Police. District department of Czech Police was the researched unit. Part of property crime and its clarifitation were researched parameters. These parameters were researched on 100 randomly chosen District department. The mentioned structure of Czech Police was supported by verifitation research hypothesis, in particular the bond of researched parameters. Researched parameters were expressed in percentual form due to the bond between them. Logical and empirical methods of applied quantitative research were used to obtain information about proceeding the property crime. All information were obtained by analyzing Police database. The research hypothesis were accepted by investigation obtained informaton: H1) Empirical distribution of researched parameters of property crime will be comparable to normal distribution. H2) Researched parameters of property crime will be close and positive related in terms of regression and corellation. The main goal of this diploma thesis was fullfiled by accepting both hypothesis (H1,H2). Teoretical benefit of diploma thesis lies in completing the main goal and in confirmation of usability methods of two-dimensional statistics. Practical benefit of diploma lies in confirmation the work efficiency at district departments of Czech Police. Work efficiency was supported by research resutls respectively by confirmation of normal distribution and positive corellation between examined parameters. Conducted research could serve as one of documents used in property crime prevency. Ambition of this diploma thesis was to highlight the need of furter research on the field of property crime.

Statistical investigation of physical readiness selected parametrs of professional firefighters within HZS South Bohemia CPS České Budějovice and HZSp JE Temelín
SEVERA, Marek
Physical readiness is an integral part of the requirements for the firefighter profession. Getting acquainted with the selected organization of units and mapping their physical training led to an understanding of the problem. Logical methods of applied quantitative research were used to obtain information. A factor (strength part of physical tests) was determined to compare the physical readiness of selected organizations. Using the application of empirical research methods, the parameterization of the selected factor was performed and the first research goal was met. Research hypotheses were positively verified by methods of investigating the obtained data: H1: Selected parameters of strength physical readiness should have an empirical distribution close to the normal distribution (normality was verified by nonparametric testing). H2: Comparison of the parameters of the strength part of physical tests of selected organizations should lead to the acceptance of the null hypothesis at the selected level of statistical significance (no statistically significant differences in the physical readiness of selected organizations were found at the selected level a= 0.05). By verifying the operationalized hypotheses H1, H2, the second goal of the work was fulfilled, the comparison of physical readiness between individual organizations. The verification of hypotheses was supported by the theory of estimates of theoretical parameters of the normal distribution and regression and correlation analysis of measured data with two dimensions of the strength part of physical tests (lying-seats, cranks). The theoretical benefits of the diploma thesis can be considered the proposed and implemented structuring of the theoretical part - a description of the organization of selected units, a description of physical training legislation, new trends in physical training, physical training abroad. The practical benefit of the diploma thesis is to document the chosen structuring of the theoretical part by selecting a suitable comparative factor - the strength component of physical tests. The applied quantitative research could have research connections - to document the chosen structuring of the theoretical part by other parameters of physical readiness and special physical training of professional firefighters.
