Circadian rhythms in human life - elaboration of the topic with elements of the flipped classroom teaching method
Křivohlavá, Tereza ; Mourek, Jan (advisor) ; Manková, Denisa (referee)
The thesis deals with an alternative teaching method called the flipped classroom, which was applied in the practical part to the topic of the biology of circadian rhythms. In the flipped classroom method, the phases of teaching are switched. Study material is created for the students and presented to them for home study before the class. In the actual teaching, there is then more time for clarifying ambiguities or consolidating material, which is the main advantage of the flipped classroom. Circadian rhythms are biorhythms repeating with a period of approximately 24 hours. The circadian system is controlled by the central circadian clock in the suprachiasmatic nuclei of the hypothalamus. These circadian clocks are synchronized by environmental stimuli, predominantly light. In the case of irregular artificial lighting, the body's circadian clock desynchronizes and disturbances in mood, cognitive performance, or physical health can occur. In the frame of the practical part of the thesis, a video was created to introduce students to the topic of circadian rhythms. In addition, worksheet assignments were created to practice and deepen students' knowledge of biological rhythms, as well as the design of an entire teaching unit with flipped classroom elements. Everything was tested on 4 groups of the...

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...

Chronotypes and Social Jet Lag Related to Obesity
Halászová, Andrea ; Fárková, Eva (advisor) ; Červená, Kateřina (referee)
In nature we can observe plenty of actions which show some kind of regularity as they repeat with a certain period. The circadian rhythm with its period of approximately one day belongs among these. The circadian rhythm is synchronized mainly by light, but there are also many other internal and especially external synchronizers such as the society we live in. In an organism many processes show circadian rhythmicity, but everyone has the rhythm adjusted individualy, thus called chronotype. It's indeed very important to note that living in harmony with the chronotype is essential. Social jet lag is the term for a long-term disbalance and circadian desynchrony as a consequence of the need to adjust this individual circadian preference to the regime set by the society we live in. Many of recent studies support the findings, that social jet lag might have an impact on health and could participate in development of some of the lifestyle diseases such as obesity. Therefore it should be found beneficial to apply those finding in a clinic practise not only in order to help with an efficient treatment of obesity and its consequences but also in preventing it.

The Quality of Life Analysis with Circadian and Diurnal Rhythms at Pubescent and Adolescent in South Bohemia Region.
VLKOVÁ, Alena
This thesis deals with quality of life with regard to circadian and diurnal rhytm of children at children´s homes in South Bohemia. The theoretical part deals with pubescent and adolescent age of a child, circadian and diurnal rhytm, sleep and life quality of children. I also describe issues of value orientation, family and upbringing at children´s institutions. The most important part of the thesis was questionnaire development. QuestionnaireThe Circadian Typology CIT Harada, Krejčí (2010). There is a group of pubescents (10-14 years) and a group of adolescents (15-19 years). My research involves children´s homes in Písek, Volyně, Radenín, Žíchovec, Koryto, Boršov nad Vltavou, Homole and in Zvíkovské Podhradí. Data collecting took place since February 2012, to October 2012. The conclusion of the thesis shows results of completed questionnaires from 118.

Aspects of Mental and Social Health of Pubescent in Relation to the Circadian rhythm.
KŘESŤAN, Tomáš
The aim of this diploma thesis is to deal with the issue of both mental and social health in relation to the circadian rhythm. This work was created at the same time as a project GAJU no. 101/2011/S. "The Psychosocial and Somatic Indicators in Comparison to the Circadian Rhythm". In the theoretic part of this work the issue of the mental and social health is solved as well as the definition and characterization of the pubescent period is given here. The matter of the circadian and diurnal rhythms is explicated here as well. In the experimental part there is a questionnaire research involving 250 pubescents (125 girls, 125 boys). The age of the pubescents ranged from 11 up to 13 years. The average age for both of the sexes was 13 years. The data capture was proceeding from May 2011 till February 2012. For this purpose the method of two standardized questionnaires was used. The questions from the social sphere originated from the questionnaire called The Quality of Life, Cummins (1997) ComQol S5. The questions solving the issue of the circadian rhythms were chosen from the questionnaire called The Circadian Typology CIT, Harada, Krejčí (2012). The gained data were evaluated by the means of the basic statistic methods and reciprocal correlation. On the basis of results I concluded that some data are correlated with social and mental health, strongly affecting the concept and the importance of sleeping. At the beginning of this work 5 hypothesis were provided. Three of them were confirmed by data analyze.
