Acute effect of head down tilt on blood pressure and haert rate
Tolar, Jan ; Radvanský, Jiří (advisor) ; Procházka, Michal (referee)
Whereas the effects of a long-term activity of head-down tilt (HDT) in the angle between 3ř and 12ř were examined in details in cosmic medicine as the model of a state of weightlessness, literature concerning effect of HDT on cardiovascular control in the angle over 30ř is scarce. The aim of the thesis is to examine acute reaction of systolic, diastolic, mean arterial blood pressure and heart rate during three minutes of 30ř, 50ř and 70ř HDT, realized on a tilt (inversion) table with fixed legs. For the combination of HDT and head-up tilt (HUT), the following protocol was chosen: 5 minutes lying in a horizontal position (HOR), 3 minutes of 70ř HUT, 3 minutes of 30ř HDT, 3 minutes of HOR, 3 minutes of 50ř HDT, 3 minutes HOR, 3 minutes of 70ř HDT, 3 minutes HOR and 3 minutes of 70ř HUT. A non-invasive continuous Peňáz method, using Finapres Ohmeda, was used to monitor beat-by-beat blood pressure and heart rate. Blood pressure was also measured by sphygmomanometer each minute for calibration. In the angle of 30ř HDT, there was a significant decline of heart frequency (p < 0,01). During the 50ř HDT, there was a significant rise of systolic blood pressure in the third minute, of diastolic and mean arterial pressure each minute and the heart rate dropped significantly (all p < 0.05). In the 70ř HDT,...

Metodiky řízení informatických procesů - implementace ISO 20000
Rajnyš, Michal ; Ing. Jan Tolar (advisor) ; Prof. Ing. Jiří Voříšek, CSc. (referee)
Increasing amount of consulting companies offering support for implementation of norm ISO/IEC 20000 and their assurance that this norm is suitable for any type of organization is bringing a question if it is in reality true. The text is considering methodologies of information processes management in MSP and is highlighting problems that can arise in this segment. The work consists of theoretical outputs as well as experience from planning the implementation of ISO 20000 in a small Business Intelligence company. In the first part of this work are methodologies put in general frame of informatics management (IT Governance) and is discussed their purpose and impacts of standardization of management processes to which their use is leading. The main attention is paid to ITIL and ISO 20000 and their mutual relationship. In both methodologies is apprised suitability for segment MSP. In scope of the practical part are defined conditions that need to be fulfilled in order to achieve successful implementation of ISO 20000 in MSP. The main output of this part is concrete methodology of implementation of ISO 20000 in a small company.
