Spirometry
Vyškovský, Daniel ; Slávik, Vladimír (referee) ; Janoušek, Oto (advisor)
This work presents spirometric measurements on a group of volunteers. First of all the physiology of respiration is explained. Further the theory necessary for measurement and analysis of respiration parameters is mentioned. A separate chapter contains information about ventilation disorders with focus on obstructive diseases. The measurement methodology is described in the analysis section. The program developed for automatic spirometric signal analysis is described in the next section. Parameters obtained from the program are statistically analysed and compared for physiological and obstructive state. Changes, which the individual parameters represent in relation to the simulated obstruction, are discussed. The appendix section contains a report to be used for laboratory lessons together with the developed program.

A probe of student´s knowledge of photosynthesis at the lower-secondary school
BOHÁČOVÁ, Nikola
This bachelor's thesis focuses on pupil's knowledge about photosynthesis and the other related processes in the terrestrial plants. The aim of the thesis was to find out misconceptions of the ninth grade pupils of elementary schools and lower grammar schools. It also deals with attitudes of teachers about teaching photosynthesis. Theoretical part of this thesis mentions physiological processes of plants and their possible misconceptions. These misconceptions are common in Czech and foreign studies. The study was realized in four elementary schools and lower grammar school using a questionnaire survey. The results of the survey declare that there are misconceptions and insufficient knowledge of plant physiology. Answers from biology teachers state that teaching biochemical processes in lower grades of primary school is difficult.

Influence of Wim Hof method on freediver performance
Pilušová, Viktorie ; Heller, Jan (advisor) ; Pavlů, Dagmar (referee)
Title: Influence of Wim Hof method on freediver performance Objectives: The aim of this thesis is to find out whether Wim Hof's method (WHM) can demonstrably improve the performance of a freediver and whether, as an added component of regeneration in his training unit, it can demonstrably contribute to the improvement of selected physiological parameters, compared to a group practicing Pranayama in combination with cold exposure and meditation and a control group without intervention. Another goal is to compare the results obtained in the individual groups for a period of two and four weeks of measurement and thus objectify the effect of the selected intervention. Methods: As part of the issue of improving the athlete's performance, selected physiological parameters of individuals engaged in freediving on the breath were observed. For the implementation, the WHM was used, which uses the connection of psychological and physical resistance to stress factors. A total of 32 healthy male subjects in the age range of 32-61 years participated in the study, who were randomly divided by lot into 3 as closely as possible groups of 10-11 members each for WHM or Pranayama training, or into a control group. The experiment consisted of an initial measurement, where input data was taken from the participants and...

Activated sludge inhibited by pesticides
Pokluda, Michal ; Pavlíková, Marcela (referee) ; Hrich, Karel (advisor)
The bachelor's thesis focuses on researching the inhibitory effects of selected pesticide substances on activated sludge present in wastewater treatment plants. The thesis is divided into a theoretical part and a practical part. The first part provides a theoretical explanation of pesticides, their presence in water, their basic classification, and the legislation addressing the issue of pesticide substances in water. The thesis also lists and describes methods for removing pesticides from water. Furthermore, the content of the theoretical part touches upon the topic of the Modřice wastewater treatment plant, primarily describing its treatment process. The practical part of the thesis involves laboratory research on the oxygen consumption rate of microorganisms in activated sludge in the presence of pesticides toxic to these organisms. The testing methodology is based on the standard ČSN EN ISO 8192.

Development of features quantifying respiratory dysfunctions in Parkinson’s disease patients
Cvetler, Dominik ; Mekyska, Jiří (referee) ; Kováč, Daniel (advisor)
In the beginning of the thesis, Parkinson's disease and hypokinetic dysarthria are briefly described, which have a negative effect on speech production and cause breathing problems during speech in sick patients. The aim of the thesis is to create an algorithm for automated detection of breaths and the design of parameters for the quantification of respiratory disorders in patients with Parkinson's disease. In the MATLAB environment, the recordings of the researched subjects were processed and an algorithm was created for the detection of breaths, which used the logistic regression method. Based on the predicted breaths, proposed parameters were extracted from the recordings, which were then statistically analyzed and compared in healthy controls and patients with Parkinson's disease. By using a machine learning model, it was possible to predict the clinical data of patients from the proposed parameters to a certain extent. The average accuracy of the model for predicting puffs was 0.85. Of the 14 proposed parameters, 6 were suitable for quantifying respiratory disorders associated with hypokinetic dysarthria. The result of the work is a functional algorithm for the automated detection of breaths in the speech signal and proposed parameters that could be useful for the quantification of respiratory disorders in patients with Parkinson's disease.

Survey of students' knowledge and teachers' attitudes to the topic of terrestrial plants photosynthesis in basic school education
ŠOBR, Zdeněk
This thesis focuses on the pupil's knowledge about photosynthesis, biomass, the teacher's attitude to teaching these issues including the use of digital educational resources. The focal point of this thesis is a questionnaire survey among primary school teachers and students, which examines the level of knowledge and personal attitudes of both groups of respondents to teaching this topic and its digitization. 154 pupils and 10 teachers from 5 different primary schools were involved in the survey. An analysis of a number of textbooks published by Fraus was also included. The results confirmed that misconceptions, which have already been described in the past, remain among the students. These include, for example: "The plant breathes when it is not performing photosynthesis. The main reason why plants perform photosynthesis is oxygen production. The plant breathes carbon dioxide and exhales oxygen." The literature and the results of this study suggest that using modern aids in science classes and in self-study could be a solution to dealing with misconceptions.
