Automated diagnosis of sleep disorders using wearable devices
Sigmund, Jan ; Mekyska, Jiří (referee) ; Mikulec, Marek (advisor)
Sleep disorders induce many negative repercussions. Furthermore, research about their connection to cognitive health is increasing in numbers. This thesis concerns detection of poor sleep quality via raw actigraphy data. Existing method for assessing sleep was selected, it’s performance was validated against polysomnography on 27 patients. Used algorithm defines sleep as the absence of change in arm angle. Resulting 81 % sensitivity, 62 % specificity and 78 % accuracy is different from the outcome in the pilot study. Two approaches, to determine sleep quality were used. Both are based on comparing sleep features – first, with National Sleep Foundation recommendations and second, with control group without sleep disorders (7 persons). The goal was to pinpoint the remaining 19 patients with diagnosis. The recommendation for SOL, WASO, NA>5 and SE had higher sensitivity (75 %), lower specificity (71 %) and identical accuracy (74 %). These approaches were then also tested on 7-day actigraphy, consisting of 27 subjects, that are presumed to have prodromal dementia with Lewy bodies. Same principle was applied to try to predict LBD and thereby address the link between sleep quality and neurodegeneration. This resulted in 86 % sensitivity, 38 % specificity and 63 % accuracy. With regard to achieving solid sensitivity in all cases and good accuracy this could be used to indicate sleep quality.

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...

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...

Analysis of quality and length of sleep in students of PF JU
ŠTĚPÁNKOVÁ, Natálie
This diploma thesis deals with the analysis of quality and length of sleep in students of PF JU. The goal was to explore how students are doing with their sleep, whether they have any sleep problems or not and how their sleep habits differ. The thesis is divided into theoretical and practical part. The theoretical part was created on the basis of Czech and foreign scientific literature and in the practical part of the work there are the survey results and hypotheses evaluation.

The Effect of Excessive Use of Modern Technologies on the Origin of Sleep Disorders in Children of Older School Age
SOUČKOVÁ, Klára
This bachelor thesis deals with the excessive use of modern technologies for the possible origin of sleep disorders in children of older school age. The theoretical part characterises older school age, sleep, sleep disorders, the specifics of sleep in children and adolescents, modern technologies and their impact on human organism and summarises available research related to the impact of using modern technologies on the sleep quality in children. The practical part presents quantitative research examining the influence of excessive use of modern technologies on the possible origin of sleep disorders in children of older school age.

Sleep hygiene of students of Charles University FPES
Beranová, Tereza ; Majorová, Simona (advisor) ; Nováková, Pavlína (referee)
Title: Sleep Hygiene of Students of Charles University FPES Objectives: The aim of the bachelor's thesis was to find out to what extent students of bachelor's programs at Charles University FPES (Faculty of Physical Education and Sport) adhere to the principles of sleep hygiene. Methods: I used the poll method for data collection for the practical part of the bachelor's thesis. The poll of my own design was created via Google Forms. The data were converted to the Microsoft Excel 2010. The basic procedures of descriptive statistics were applied to process the data. The research was focused on a group of students of full-time bachelor's programs at Charles University FPES. Results: The poll results showed that most students only partially follow sleep hygiene. Only 12 (10.3 %) students out of 116 (100 %) participators adhere to almost all recommended sleep hygiene principles. For the rest of the students, it was recommended to eliminate negative factors affecting sleep. Keywords: sleep, insomnia, sleep disorders, regeneration, addictive substances, circadian rhythm, EEG
