The modulation of the circadian rhythm in melatonin production in human induced by experimental lighting conditions
Skálová, Kateřina ; Bendová, Zdeňka (advisor) ; Jelínková, Dana (referee)
The circadian system controls the timing of most of the physiological functions and behaviour within approximately 24 hours period. The light/dark cycle aligns this circadian period with the exact length of the solar day. Light information is conveyed via ipRGC cells in the retina, with maximum sensitivity in the blue part light (460-480nm wavelength). The information proceeds to the main circadian clocks located in the suprachiasmatic nuclei. This clock regulates the synthesis of neurohormone melatonin in the pineal gland whose high night level can be rapidly downregulated by the light at night. The major aim of this study was to test the effectiveness of the blue or green light-emitting device, potentially utilized in clinical practice, to suppress the night melatonin level and provide thus the first evidence that this device may affect the circadian system. The results show that the light emitted by this device has the potential to lower melatonin levels in most subjects with the higher efficiency in the blue range. Key words: circadian rhythms, melatonin, light pulse, eyelids, blue and green light
Circadian system and memmory
Skálová, Kateřina ; Bendová, Zdeňka (advisor) ; Houdek, Pavel (referee)
Circadian system is a part of all living organisms. It controls suitable timing of their physiological functions and behaviour. The molecular mechanism of interlocking transcription-translational feedback loops of clock genes and their protein products forms the core of the circadian system. The main structures of this system in mammalian organisms are suprachiasmatic nuclei of the hypothalamus. Memory is also closely connected with circadian system. It is one of the most important abilities of organism for creating knowledge. Both memory and circadian system enable to the organism to adapt to changes in its external environment. The expression of clock genes was detected in brain structures involved in mediation of memory such as hippocampus, amygdale and basal ganglia. The oscillations of these clock genes influence the formation and retrieval of memory traces. The aim of this work is to summarize current knowledge about the relationship between the memory and the circadian system. Key words: circadian system, memory, clock genes, suprachiasmatic nuclei, hippocampus
Preparedness pre-school padagogue for integration/inklusion of childern with mental retardation
SKALOVÁ, Kateřina
Bachelor's work title Preparedness pre-school pedagogue for integration/inclusion of children with Mental Retardation is divided to three parts in its theoretical chapters. First chapter summarizes the knowledge about the children with mental retardation. Second chapter is about how to raise and educate the children with mental retardation and in this field the chapter approaches historical contexts in details. Last theoretical chapter explains the concept of the intergartion and inclusion. Practical part shows the results of the investigative surveys. I was trying to find out, if the teachers at ordinary nursery schools are ready for inclusion of the children with mental retardation. I have chosen qualitative survey for a practical part. Methods of gathering the facts were chosen as half structured interviews.
Comparison of Online Marketing Communications in the Czech Republic and Austria
Skalová, Kateřina ; Král, Petr (advisor) ; Bockstefel, Jan (referee)
The topic of this diploma thesis is comparison of online marketing communication in the Czech Republic and in Austria. The aim of this thesis to compare online marketing communication in the Czech Republic and Austria, describe its characteristics, identify main differences and analyze essential reasons for the differences. After the introduction part, in the second chapter, the theoretical grounds of marketing communication, internet, its characteristics and history, as well as online marketing communications are described. In the third chapter, both markets are described in detail, in terms of internet users, situation on the marketing communications markets and in terms of media consumption. In the fourth chapter, main common features and differences are analyzed. In the last chapter, the most significant reasons for the differences are analyzed, first in terms of macroeconomic influences, second in terms of the industry itself and third in terms of individual preferences. The main sources for the diploma thesis were theoretical books concerned with marketing communication, online marketing communication and internet, written in Czech, English and German. Furthermore, statistical data of national statistical offices, articles from magazines and online sources, printed and online studies of selected associations or companies as well as interviews with experts are used.
