Bijota, Jan ; Mžourek, Zdeněk (referee) ; Galáž, Zoltán (advisor)
This thesis deals with speech analysis of people who suffer from Parkinson’s disease. Purpose of this thesis is to obtain statistical sample of speech parameters which helps to determine if examined person is suffering from Parkinson’s disease. Statistical sample is based on hypokinetic dysarthria detection. For speech signal pre-processing DC-offset removal and pre-emphasis are used. The next step is to divide signal into frames. Phonation parameters, MFCC and PLP coefficients are used for characterization of framed speech signal. After parametrization the speech signal can be analyzed by statistical methods. For statistical analysis in this thesis Spearman’s and Pearson’s correlation coefficients, mutual information, Mann-Whitney U test and Student’s t-test are used. The thesis results are the groups of speech parameters for individual long czech vowels which are the best indicator of the difference between healthy person and patient suffering from Parkinson’s disease. These result can be helpful in medical diagnosis of a patient.

Implementation of KDE+ statistic method
Svoboda, Tomáš ; Popela, Pavel (referee) ; Bíl,, Michal (advisor)
In this master's thesis I presented a new statistical method KDE+ (Kernel Density Estimation plus) that allows detecting clusters of points on the linear data. I created a self-standing application that enables anybody to try the method and apply it on their own data. One possible usage of the method and application is for the detection of critical roads sections with a high concentration of traffic accidents. Development of the application includes analysis of KDE+ statistical method, design of appropriate program structures and the implementation. Optimization were carried out to achieve higher performance after creating the prototype. At the end the software was validated by analysing vehicle collision data from the police database of the Czech Republic.

Use of NIC and NOC nursing care in the standard units
VACULČÍKOVÁ, Jitka
The thesis is focused on the up-to-date issues of application of NIC and NOC to nursing care at standard wards. Implementation of unified nursing language is a great challenge for Czech nursing. Application of unified professional terminology and standardized electronic data improves effectiveness of cooperation between health care staff from different facilities and develops nursing statistic registers, which are useful for development of research in nursing care and substantially improve the quality of nursing care in heath care facilities. This thesis is a part of research grant project implemented by the Department of Nursing of the Faculty of Health Care and Social Studies of the University of South Bohemia in České Budějovice, GAJU JU 079/2010/S, called Application of conceptual model and classification systems to nursing documentation. In the theoretical part we map the basic theses, principles and novelties of development, classification systems, particularly from foreign literature. We set four basic goals before the research, focused on application of classification systems to standard departments, on the aspects affecting introduction of classification systems to standard departments, elaboration of proposals and solution of application of classification systems and verification of application of classification systems to standard departments. The research was implemented in cooperation with the following South Bohemian workplaces: České Budějovice Hospital, Český Krumlov Hospital, Jindřichův Hradec Hospital, Prachatice Hospital, Strakonice Hospital, Tábor Hospital, and Písek Hospital. The empiric part was based on qualitative-quantitative method. We chose the techniques of document content analysis and semi structured interview. The quantitative research was based on questionnaire research. We examined the diagnostic-nursing management from selected documents from the involved hospitals by means of content analysis. We conducted interviews with head nurses and we particularly focused on the spheres of nursing documentation topics and diagnostic classification systems. Three research questions were linked to the interviews. The interviews were interpreted in the form of thought maps. The questionnaire research was designed for general nurses from standard surgical and internal wards. Four hypotheses were related to the questionnaire research. The quantitative data were processed in statistic form; we used frequency tables and also worked with the chi-square test of compliance. A basic nursing diagnostic module according to NANDA-I, NIC and NOC, which has been presented to nurses ? professionals from practice ? for testing is the output of the thesis. Nursing specialists were informed on the content analysis results at the 3rd South Bohemian Conference of non doctoral health care workers in České Budějovice.

Implementation of Statistical Functions Using HLS
Šinaľ, Peter ; Martínek, Tomáš (referee) ; Dvořák, Milan (advisor)
The aim of this thesis was to design and implement selected statistical functions used in technical analysis. I focused on moving averages, Black-Schles model for calculating option prices and Indicator Delta. These functions are through HLS transformed into an appropriate description for programmable FPGA. During the transformation process, emphasis is on low latency and resource consumption. Created solutions demonstrate the potential of HLS. They show complexity of the technical analysis and hardware requirements. Achieved results show high accuracy in the simulations. Deviation from the reference value is approximately 6,615*10e-3. The results also indicate thet that reducing latency does not necessarily cause an increase in the consumption of resources on the chip.

The role of general practitioner nurse in the prevention of the colorectal cancer in surgery.
TETÍKOVÁ, Hana
Current situation: The Czech Republic belongs to countries with high prevalence of colorectal carcinoma (CC). The theoretical part of this thesis includes basic information on carcinoma of the colon and the rectum. It also deals with its causes, symptoms and treatments. Primary, secondary and ternary prevention of CC is described in detail. Also the role of the nurse in general practitioner´s (GP) office in such prevention in adults is thoroughly investigated. Aims: Main aim of this work was to find the level of patient knowledge about the prevention program on CC and to map the role the nurse in GP office for adults has in this prevention. Methodology: Both qualitative and quantitative methods were chosen for this research. Obtained data was transferred into data matrix, evaluated using contingency tables and for statistical evaluation the one-sample and the two-sided t tests as well as the chi square test were used. The second method used was qualitative research in the form of structured interview. The interviews were transcribed into text. Through open coding analysis four categories were identified: The primary prevention of CC, The secondary prevention of CC, The immunochemical test for occult blood and The tertiary prevention of CC. Research group: The first research group consisted of patients aged 50 and above. The second research group consisted of five nurses working in the GP offices. Results: The first aim was to establish the level of knowledge in patients about CC. Four hypotheses were stated in order to fulfil the first aim. First hypothesis was: "Patients are informed about the prevention of CC". The level of significance for this hypothesis was calculated to 48.1 % and the hypothesis was therefore confirmed. However, reserves were discovered regarding the information on the primary prevention and first information about the secondary prevention is seen to dominate. This means that the research showed that patients that seldom visit the GP office fall through the CC screening. It is therefore very beneficial that a project has started from January 2014 with addressed invitations to the targeted population to such CC screenings. Second hypothesis presumes that "The knowledge of prevention of CC is gender indifferent". However, the reached level of significance at 2.2 % declines this hypothesis which means that the knowledge does differ based on gender. In fact the results show that women possess deeper knowledge on this subject. For example more women believe that smoking influences the prevalence of CC. The third hypothesis was supposed to either confirm or disprove that people are equally well informed about CC prevention in urban and rural areas. The level of significance of 1.2 % shows that this knowledge is better in urban areas. The last, fourth hypothesis asked whether patients have acquired their knowledge of CC prevention in the GP office. The level of significance for this hypothesis is 88.6 % and confirms the question. The second aim of this research was to map the role of the nurse in the GP office regarding the prevention of CC. The research question asked was" What role does the nurse have in CC prevention?" The research shows that her role is both irreplaceable and very significant.
