The influence of the Media on the Lifestyle of Teenagers
Richterová, Karolína ; Wolák, Radim (advisor) ; Lütke Notarp, Ulrike (referee)
This thesis examines the impact of media on adolescents' lifestyles, more specifically on two aspects of lifestyle, namely physical activity and sleep. Within the Covid-19 pandemic period, individuals were forced to stay in their homes, and all their social contact, as well as school and work obligations, shifted to the online environment. With this, screen time also increased, as did the associated sedentary behaviour. As they were all forced to be isolated, sports and leisure activities were also very limited or often also transferred to the online environment. The aim of this thesis is therefore to try to define the habits of adolescents in terms of physical activity, sleep and media consumption, and how these aspects are interconnected, and whether adolescents perceive this interconnection. The aim was also to provide some education to the individuals, where they were then confronted with recommendations for particular aspects of lifestyle (sleep and physical activity), but also recommendations regarding media consumption. As lifestyle was strongly influenced by the Covid-19 disease pandemic, the aim was also to see how individual students' habits changed within this period, but also afterwards. Within the framework of this work, qualitative research was conducted. Using in-depth interviews...

Genetic factors in the etiology of sleep disorders
Dvořáková, Markéta ; Šolc, Roman (advisor) ; Červená, Kateřina (referee)
Sleep disorders are a group of disorders affecting a considerable part of proportion of the human population. Their aetiology is usually very complex and includes environmental and genetic factors. The nature of these disorders is often multifactorial. Sleep medicine and the field of synthesis of its findings with those of modern or classical genetics still offer quite a huge possibilities of research. However, despite many unresponsed questions, it is now possible to summarise the identified confirmed or suspected genes whose mutations are involved in the causes of these disorders. It is possible to estimate the heritability of certain disorders based on their multiple occurrence in families, presence in twins or prevalence in the population across different ethnics. This bachelor thesis focuses on genetic aspects in the etiology of sleep disorders, their heritability, the strength of the genetic component, and genetic links between some of the disorders.

Influence of binaural beats on ideomotoric coordination
Pavlovič, Ondřej ; Pánek, David (advisor) ; Pavlů, Dagmar (referee)
Name: The effects of binaural beats on sleep quality: a systematic review Aims of the study: The main objective of this study is to present the possibilities of influencing stress and sleep, to determine the effect of binaural beats (BB) stimulation on sleep quality and parameters, and to determine the specifics of effective BB therapy based on the available data. Materials and methods: This systematic review includes scientific articles and clinical studies published in relevant and/or peer-reviewed journals and conference proceedings. Three electronic databases (Web of Science, Scopus, PubMed) were searched for all available sources published from 2000 to January 2023 in English language. The search was conducted using relevant keywords and their combinations. The screening and subsequent process of elimination was based on set of eligibility and inclusion criteria. Results: Total of fourteen studies met the eligibility criteria. BB stimulation increased subjectively perceived sleep quality and reduced mental tension. Objectively, it reduces time of falling asleep, accelerates the onset of deeper sleep stages (N2 and N3) and increases their duration, as well as the total sleep time. The parameters optimal for effective BB stimulation can be laid out as follows: BB in the frequency range of 2 to 4...

Sleep and the consequences of its lack on university students
Soukupová, Barbora ; Thorovská, Alena (advisor) ; Zvírotský, Michal (referee)
This bachelor's thesis is called Sleep and the consequences of its lack on university students. The work is divided into two parts. In the theoretical part are mentioned general characteristics of sleep, history, circadian rhythms, phases and meaning of sleep. Furthermore, attention is also paid to selected sleep disorders, possible causes, and finally the consequences that can occur during sleep deprivation. The practical part is carried out with the help of semi-structured interviews with respondents, followed by an analysis of the interviews, a comparison of individual data and a discussion in which the answers to the research questions are summarized and the results compared with the professional literature. The main goal was to find out the consequences of lack of sleep on university students, when it was found that the most common problems are with attention, memory and mood changes, as well as greater susceptibility to diseases. A partial goal investigated the possible causes that contribute to impaired sleep on university students. The research showed that the most common causes were stress and caffeine. Another partial goal was to find out how the quality of sleep subjectively changes in university students during the exam period. The results pointed to a reduction in sleep time, worsening...

Sleep dynamics analysis using electrophysiological features
Lampert, Frederik ; Janoušek, Oto (referee) ; Mívalt, Filip (advisor)
Táto práca sa zaoberá metódami detekcie spánku pomocou elektrofiziologických príznakov, bez dostupnosti anotácií v podobe hypnogramov. Vyhodnocovanie spánku pomocou polysomnografických (PSG) dát je časovo apersonálne náročný proces, ktorý sa odohráva zväčša vnemocničnom prostredí. Moderné implantabilné zariadenia schopné kontinuálneho snímania azdieľania dát otvárajú možnosť dlhodobého akontinuálneho monitorovania spánkovej aktivity upacientov snurologickými chorobami v domácom prostredí. Súčasné metódy na spánkovú detekciu využívajú intrakraniálne elektroencefalografické (iEEG) spánkové klasifikátory, ktoré sú tvorené a validované na štandardných polysomnografických dátach. Tie však nie sú vždy kdispozícii čo vedie kpotrebe vyvinutia metódy spánkového hodnotenia, ktorá by bola schopná analyzovať spánok pomocou elektrofyziologických príznakov aj bez dostupnosti anotácií v podobe hypnogramov ato obecne z malého počtu zvodov. Za týmto účelom bola navrhnutá metóda spánkového hodnotenia, ktorá vyhodnocuje spánok na základe výkonu elektroencefalografické (EEG) signálu v spektrálnej oblasti pomocou metrík zvaných Power in Band (PIB) metriky. V tejto práci bol analyzovaný výkon vdelta pásme (0,5-4 Hz), keďže EEG signál má vňom najvyššiu amplitúdu azároveň je jeho aktivita najviac výrazná počas N2 aN3 spánkových cyklov, ktoré sú najviac zastúpené vspánku počas noci, takže poskytujú najlepšiu informáciu orozložení spánku počas noci. Scieľom validácie PIB metrík boli taktiež predstavené štandardné metriky založené na hypnogramoch. Tieto metriky boli následne implementované do programovacieho prostredia Python a aplikované na dva voľne dostupné datasety, Dreem Open Dataset-Healthy (DOD-H) a Dreem Open Dataset-Obstructive (DOD-O) obsahujúce polysomnografické merania 25 zdravých jedincov (DOD-H dataset) a56 jedincov so syndrómom spánkového apnoe (OSA)(DOD-O dataset). Výsledky analýz boli vyhodnotené pomocou vizuálnej analýzy vo forme boxplotov, korelačných matíc a štatistických testov. Z výsledkov analýz vyplýva, že navrhnuté PIB metriky majú schopnosť rozlišovať medzi fyziologickým a patofyziologickým spánkom, avšak ich schopnosť rozlišovať niektoré aspekty spánku sa líši od štandardných metrík založených na hypnogramoch. Ztoho vyplýva, že PIB metriky nenahrádzajú štandardné metriky, ale skôr ponúkajú inú perspektívu na analýzu spánku.
