Small mammals in diet of barn owl in the Eastern Meditarranean
Šindelář, Jiří ; Horáček, Ivan (advisor) ; Anděra, Miloš (referee)
The extensive material of skeletal remains of mammals from a diet of barn owl in the eastern Mediterranean has been processed and evaluated with different techniques of chorological and morphometric analysis. At least 8400 individuals of 45 species of insectivores, rodents and bats were found in our total collection of samples, which represents a significant portion of fauna of the region. We have evaluated a chorological composition of the taphocoenoses and the interregional differences, manifested primarily by differences in the representation of satellite and accessory elements. We found a highly significant impoverishment of the isolated island taphocenoses (Cyprus, Karpathos, partly on Crete), where Cricetidae, Arvicolidae, C. leucodon etc. are missing. On the other hand the essential part of the dominance structure takes up the Rattus rattus, which acts here as an invasive species, significantly more successful than in the ragged continental contexts. The species diversity of the examined samples is positively correlated with the geographic latitude (taphocenoses of the northern regions are significantly richer) and negatively with the island effect and the degree of aridization. The morphometric analysis of the three most abundant species of Soricidae within the studied region showed...

Collaboration nurse and family members of patiens with brain injury
LIŠKOVÁ, Sandra
The bachelor thesis deals with the cooperation of nurses and family members of patients with brain injuries. Brain damage is among the most serious injuries a person can have. Brain injuries are the second highest cause of death after abdominal trauma. People often confuse the term head injury with brain injuries. The lasting consequences of these injuries are very severe and often fatal. The skin on the scalp can indeed bleed, but we can only talk about brain injury if there is any actual damage or suppression of the brain issue, which can have many causes.The theoretical part describes the most common injuries of the brain; changes in behavior and fatic disorder in a patient with a brain injury, nursing care of patients with brain injury, communication between the nurse, the patient and his family, and also notes the importance of the nurse patient relationship and the significance of the patient's family. In the theoretical part, we have tried to give comprehensive and understandable information about the cooperation of nurses and family members of patients with brain injuries.For the empirical part of this thesis, a qualitative investigation was chosen. We used the method of data collection in the form of semi-structured interview . The survey was carried out in February 2014. Interviews with correspondents were videotaped and subsequently transcribed and processed by categorization of data. For the process the main category and subcategories were established which are, for clarity, shown in the diagrams . The interviews with correspondents were running at the University Hospital in Motol. After the approval of the matron the research investigation was initiated . Correspondents were asked prepared questions , depending on how the conversation developed, supplementary questions were considered. Interviews with nurses and family members were done separately because of the possible influence the nurses could have upon the family members. All interviews with the nurses and the family members were conducted at the University Hospital in Motol. The duration of the interview was approximately 45 minutes. At the beginning of the meeting with the correspondent, the basis of the interview was outlined and the reason for the interview was explained. None of the corcorrespondents minded the interview being recorded. Each interview was obtained with oral consent and explanation of anonymity.During the processing of the interviews, the method of open coding was used. Each sister and family was assigned a number. Then the answers of the nurses and the family members were numbered in the interviews. The rows have been numbered due to the possibility of referring to them. This method is called "paper and pencil" because of a synoptical process. For example, a nurse said line 3 and it is displayed as N1/3. A total of one main category and seven subcategories were established in both groups of corcorrespondents . The created categories and subcategories can be seen in the diagram one and four. The individual subcategories were depicted in the empirical investigation with the addition of interviews and quotes. The interviews were recorded on a CD, which is part of the thesis.The research sample consisted of two groups. The first group of correspondents consisted of nine nurses aged 24-50 years. Six nurses of all the interviewed completed tertiary education, two correspondents studied at a college and one respondent reached secondary education. Four correspondents were from the Neurosurgical Department, two correspondents from the Department of Anesthesiology and Resuscitation (ARO) and three correspondents from the Department of Chronic Resuscitation and Intensive Care (OCHRIP). The second group of the researched sample were relatives. The second group of the study sample was made up of four relatives, in varying relation to the patient, the families were in the age range from 30 years to 68 years.

Růst Mycobacterium smegmatis na agarovém médiu a agarovém médiu pokrytém celofánovou folií - morfologická a proteomová studie
Ramaniuk, Volha ; Weiser, Jaroslav (advisor) ; Beranová, Jana (referee)
Biofilm formation is one of the most common bacterial survival strategies. Majority of bacterial species are able to form these three-dimensional structures, including pathogens like Mycobacterium tuberculosis. Representatives of Mycobacterium genus widely occur in the nature, although they can cause serious problems when they appear in medical equipment and artificial replacements of the human body. Non-pathogenic Mycobacterium smegmatis mc2 155 was used as a model organism in our experiments. We investigated morphology of the three- and six-day-old colonies (in fact biofilms) on agar and agar covered with cellophane using Stereo microscope and Scanning Electron Microscope. We found that a type of surface as well as a carbon source has a great influence on the morphology of the M. smegmatis colonies. We isolated proteomes from the agar and cellophane cultures and from planktonic culture. Two-dimensional electrophoresis was used as the main proteomic method. Proteomic data were analyzed using PDQuest software. Then the sets of proteins detected by qualitative and quantitative analyses were compared using Venn diagrams. As a result, we recognized 7 unique proteins that might be specific for recognition and adhesion of bacteria to the cellophane, no unique protein in agar proteome and 46 unique...

Aesthetic standards in art education
Podlipský, Rudolf ; Slavík, Jan (advisor) ; Janík, Tomáš (referee) ; Hazuková, Helena (referee)
In this thesis paper, application of aesthetic norms in visual art education has been studied from the explanatory point of view of structuralism (with an emphasis on Czech Structuralism). The study has been carried out as a qualitative research focused on didactic analysis of teaching processes. The aim has been to find out the extent of impact aesthetic norms may have on visual art education teaching process; to examine ways of handling aesthetic norms by teachers during the lessons; as well as to verify or newly develop a fundamental conceptual apparatus enabling to handle the aesthetic norms issue within visual art education lessons in a material way. The study is grounded in records of standard teaching units (written records of lesson observations; videotaping). In his study, the author applies the concept analysis method - a methodological means for didactic reflection and evaluation of teaching based on creative tasks and activity approach.
