Module for Electrodermal Activity recording
Vičar, Tomáš ; Harabiš, Vratislav (referee) ; Bubník, Karel (advisor)
This thesis describes electrodermal activity (EDA) and its origin based on the properties of the skin and thermoregulation of body. EDA is a signal having a close relationship to psychophysiology and its help we can evaluate a variety of emotional, motoric and attentional effects on the human organism. The thesis also discusses the possibility of sensing skin potential and conductatce and how to construct a module for its scanning and uploading to computer.

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.

Mammalian energetic savings in subterranean environment. The case of African mole-rats.
OKROUHLÍK, Jan
Mole-rats are placental mammals which are perfectly adapted to subterranean life. In this thesis I present novel findings on working metabolism and thermoregulatory physiology of mole-rats. These animals cope with low availability of food and have thus employed multiple strategies how to conserve energy and/or use it more effectively. Among other adaptations this resulted in lower resting body temperature, tolerance to increase in body temperature during exercise or while at rest, surprisingly efficient cooling while digging and precise diurnal and seasonal timing of activity with regards to environmental conditions. My focus in this work is on the digging metabolic rate and thermoregulation of social Fukomys mechowii and solitary Heliophobius argenteocinereus in soft and hard substrate, thermoregulatory abilities of Fukomys darlingi, seasonal changes of activity in free living Heliophobius argenteocinereus measured as daily energy expenditure and, finally, energetic consequences of the daily activity patterns of Fukomys anselli.

Pre-hospital Emergency Care for Person with Hypothermia
HONZEJKOVÁ, Barbora
Hypothermia is condition, when the temperature of the body drops below 35 °C. This specific shock caused by unfavourable surrounding circumstances can lead into a seriously threatening life condition of the patient. It is necessary to recognize the hypothermia and give the patient adequate care. The aim of my work is to map the knowledge to recognize the area of Hyperthermia for the medical rescue staff of the Medical rescue services in South Bohemia. Hypothesis was given one, H 1: Medical rescue workers know how to review the problems of hypothermia as a whole complex. In the practical part was used quantitative research. All the data were gathered via questionnaires which were distributed in regional centres for Medical Rescue services in South Bohemia. Record were evaluated and processed into the Pie and column graphs. The representation of respondents was almost equal according to gender of the participants with the various length of practice in this service. Only four out of twenty trivia questions related to problems of hypothermia reached the set limits of 75 % correctness. The results of this research show that the medical rescue worker do not have sufficient knowledge about the hypothermia. This could be caused by lack of information about this subject in Czech literature. Problems of hypothermia should be more taught at Medical schools for future medical rescue workers. And for those who are already employed by the Medical rescue service should be provided training courses or seminar on this subject. Medical rescue workers in South Bohemia region do not have sufficient knowledge about the problems of hypothermia which means that the hypothesis H 1 was not proved.

Bioenergetics of reproduction and postnatal development of two species of social mole-rat of genus \kur{Fukomys}
ZEMANOVÁ, Milada
The resting metabolic rate of mole-rats was measured with a close-flow respirometry system and body temperature was recorded with a rectal thermometer at an ambient temperature within and below adult thermoneutrality range. The development of ability to thermoregulate was monitored for pups of Fukomys sp. Huddling and presence of adults reduced the body heat loss of pups of all monitored age, but no effect was observed on the metabolic rate of the pups until they were two months old. Huddling had no effect on resting metabolic rate and body temperature in adult giant mole-rats Fukomys mechowii. The maternal cost of reproduction was evaluated in females from two species of the genus Fukomys. The energetic expenditure of females increased with pup´s age.

The Thermoregulatory Abilities in a Mole-rat \kur{Fukomys darlingi} and its Development in Pups
ZEMANOVÁ, Milada
The oxygen consumption and body temperature were measured in adults and pups of a social Mashona mole-rat(Fukomys darlingi)to test poikilothermic traits in this species and effect of presence of adults on pup´s thermoregulation abilities. The adult´s resting metabolic rate was 0.76 {$\pm$} 0.20 mlO2g-1hod-1 in the thermoneutral zone 27-34°C. We did not confirm poikilotermic traits in this species, because body temperature was stable (33.0 {$\pm$} 0.5°C) at low ambient temperatures. The pups started to thermoregulate in age of one month and they are able to maintain stable body temperature very late in age of three months. My results indicate that presence of adults is necessary for thermoregulation of pups.
