Ion balance and its effect on heart function, measurement and analysis of ECG
Štrbková, Lenka ; Nováková, Zuzana (referee) ; Wilhelm,, Zdeněk (advisor)
Mechanical heart function is based on electrical changes at the level of cardiac cells. These electrical changes are primarily affected by the distribution of ions, intra-and extracellularly. Kidneys are very important for the physiological regulation of ion homeostasis in the body. The ion homeostasis is disrupted in case of the kidney function failure. The aim of this thesis is to compare ion values, acid-base balance before and after dialysis, and also possible changes in ECG time intervals before and after dialysis of these patients. The thesis also deals with the description of the electrocardiographic signals and the implementation of the program for ECG signal analysis. I used the ECG signals from the available database „PhysioBank“ for testing the developed program.

The skin conductivity and its use in clinical practice
Javorčeková, Lenka ; Kozumplík, Jiří (referee) ; Nováková, Zuzana (advisor)
The aim of bachelor thesis is to acquaint with the measurement of the skin conductivity and its use in a clinical practice. The applied protocol is based on a current measurement of the skin conductivity in the resting and stressful conditions. The endurance previsions were created through listening to the most favourite and the most unpopular songs. This fact was detected before the measurement on the ground of completed questionnaires.

Economic Evaluation of Public Investment Projects
Nováková, Zuzana ; Adlofová, Petra (referee) ; Hromádka, Vít (advisor)
The thesis deals with the evaluation of economic efficiency that benefits the public investment project. The aim of this study is to compare the estimated project costs with the costs actually incurred. The theoretical part describes the theme of public sector cost-output methods, and in detail analyzes the cost-benefit analysis. Furthermore, this section deals with regional policy and subsidy resources used to finance public projects. The practical part describes the project funded by funding from the European Union, which compares the value of all expected costs needed for an application for a grant with the real values of costs after project implementation.

Transcutaneous electrogastrography
Davidová, Lenka ; Závodná, Eva (referee) ; Nováková, Zuzana (advisor)
The aim of this thesis is to introduce the physiology and pathophysiology of the gastrointestinal tract, with functional parameters and appropriate diagnostics. The thesis also deals with transcutaneous electrogastrography devices and presents a suggestion of a measurement protocol which would involve a group of volunteers in fasting and postprandial states. The theoretical part describes the function of the gastrointestinal tract, detailing the analysis of gastric myoelectric activity and gastric motility. It also outlines technical and formal aspects of the parameters, artefacts and subsequent data analysis. In the practical part, a program is designed and implemented in the Matlab computing environment for the analysis of EGG recordings. Furthermore, differences between parameters in fasting and postprandial states are evaluated.

The measurement of cardiovascular parameters
Žáková, Monika ; Kratochvíla, Jiří (referee) ; Nováková, Zuzana (advisor)
This paper summarizes the problems of physiology of the cardiovascular system, with a focus on cardiovascular measurements during physical activity. It describes the diagnostic tools Cardiovit AT-104 (Schiller, Switzerland) and PowerCube (Ganshorn, Germany), used to spiro-ergometry measurements. It provides options to export data and work with them. It proposed protocol for the measurement of a small group of volunteers, by which we measure basic diagnostic parameters before, during and after physical activity. The MATLAB application is created, allowing clear analysis of measurement records. The final part contains a statistical assessment affected by physical activity on the measured parameters and a comparison of results with the available literature.

Thermal comfort and its estimation
Žáková, Monika ; Vondra, Vlastimil (referee) ; Nováková, Zuzana (advisor)
This paper summarizes the problems of human thermoregulation and its measurement, with a focus on the method of indirect calorimetry in resting conditions at different ambient temperatures and during physical activity. It also introduces the issue of human thermal comfort and the methodology of its monitoring using thermal manikin. It describes PowerCube Ergo (Ganshorn, Germany) and Cardiovit AT-104 (Schiller, Switzerland), the diagnostic devices used to spiro-ergometry measurements. It introduces the options to export data. The work proposes the protocol for measuring the thermoregulation of the small group of volunteers, which is realized by the practical part. According to the same protocol is monitored thermal comfort of the thermal manikin. In MATLAB is created the application, allowing clear analysis of measurement records. The data are evaluated and discussed.

Evaluation of Economic Efficiency of the Business Plan
Nováková, Zuzana ; Dufek, Zdeněk (referee) ; Korytárová, Jana (advisor)
The aim of this bachelor´s thesis is the evaluation of economic efficiency of the public benefit of the investment project. The aim of the thesis is measurements of embedded costs to final outputs of the project for qualified investment decisions. The theoretical part describes the topic of public sector, cost-output methods and discusses in more detail the procedure for processing and purpose and structure of the cost benefit analysis. Practical part looks on the feasibility study including analysis of costs and benefits of public sector and its alternative financing opinion by the grant program of the European union

Measurement of basic parameters of the cardiovascular system using a stress test
Matoušek, Denis ; Janoušek, Oto (referee) ; Nováková, Zuzana (advisor)
The bachelor's thesis describes the measurement of basic parameters of the cardiovascular system using a physical test on a bicycle ergometer, their processing and evaluation with the subsequent division of subjects into individual categories according to their physical fitness. The main goal of this work is to create a script in the MATLAB environment, which will be used to evaluate the results of the measured person in the student tasks taking place in practical exercises in physiology at the Faculty of Medicine, Masaryk University.

Continuous measurement of blood pressure
Kopčil, Petr ; Chmelař, Milan (referee) ; Nováková, Zuzana (advisor)
This paper deals with the physiology of cardiovascular system, explains elementary principles related to blood flow physiology and describes some basic mechanisms for regulation and blood pressure measurement. The paper also includes a description of the medical device, known as the Finometer (FMS, Netherlands), for continuous non-invasive blood pressure measurement and suggests a way to data export from this device to a text file. It introduces user friendly application to manage recorded data written in MATLAB. There is a statistical test to assess the difference between two statistical data files in the last chapter of this paper which includes a comparison our results with studies made in Czech Republic and other countries too.

The underground garage in Brno-City
Nováková, Zuzana ; Rupp, David (referee) ; Horák, Vladislav (advisor)
The thesis focuses on the design of the underground garage in the centre of Brno under the Petrov hill. The main target of the thesis is to design spatial arrangement of the underground space and its feasibility study. In the following parts the design of the structural solution and its check calculation is carried out.
