Comparison of spirometric instruments' precision
Chmelíková, Lucie ; Janoušek, Oto (referee) ; Slávik, Vladimír (advisor)
This thesis deals with pulmonary testing with emphasis to spirometry. In the first part is introduced and described pulmonary system and its attributes. There is a clear and complete list of pulmonary characteristics and parameters. It contains integrated summary of principles that are used for pulmonary measurement devices. First part is followed by description of created virtual device using LabVIEW programming. Simple meter of lung volumes can easily create spirometric curve and automatically evaluate desired values of volume. Program is further enhanced with optional archiving of measured spirometric curve. The last part of this thesis uses statistic testing for deciding of validity or invalidity of hypothesis. By statistic testing of hypothesis we are gaining and expanding basic knowledge about spirometric devices.

Face-detection based touchless measurement of heart rate
Chmelíková, Lucie ; Potočňák, Tomáš (referee) ; Janoušek, Oto (advisor)
This thesis deals with the study of contactless and noninvasive methods for estimation of heart rate. Contactless measurement is based on capturing person faces by video camera and from sequences of pictures are estimated values of the heart rate. The theoretical part describes heart rate and methods that are being used to estimate heart rate from color changes in the face. It also contains testing of tracking algorithms. Practical part deals with user interface of program for contactless measurement of heart rate and its software solution. Thesis also contains statistical evaluation of program functionality.

Lifestyle patients with psychiatric illness
Chmelíková, Lucie ; Matoulek, Martin (advisor) ; Anders, Martin (referee)
Introduction: Obesity in individuals with psychiatric disorders is normal nowadays. The aim of this research was to determine the lifestyle and the causes leading to obesity in these individuals. Methods: The quantitative research was conducted at the department D3 and III. 1. Internal Clinic at the Faculty of Medicine and at the General Faculty Hospital in Prague, at the psychiatric hospital Bohnice and on the Internet. The data were obtained through a questionnaire survey. The goal was to determine what basic eating and exercise habits the respondents with selected psychiatric disorders have, whether they are smokers and how they are burdened with diseases of civilization compared to the control group. The results: Data analysis revealed that respondents with psychiatric disease show more type 2 diabetes mellitus, heart disease and high blood pressure (89%) in the family and personal history. The results also showed that these individuals are more frequent smokers. Of the selected respondents, 46% were smokers, whilst 60% were smokers in the control group. According to 51% of respondents, overeating and according to 57%, little movement has the biggest impact on weight gain. In food preferences, psychiatric respondents reported the highest representation (62%) of vegetables and fruits. In...
