Design of hearing aid
Svoboda, Adam ; Janoušek, Oto (referee) ; Kolářová, Jana (advisor)
This bachelor’s thesis deals with the physiology of the auditory system and defects that cause temporary or complete deafness. It was created program in Matlab, which allows modification of the speech signal to simulate hearing loss and subsequent multi-channel amplification, presenting function of the digital hearing aid. It also deals with distribution of hearing aids according to the material and software and there is dismantled some modern systems from Siemens and functions that may include hearing aids.

Molecular genetic analysis of rare ocular disorders in Roma population from the Czech Republic
Rysková, Natálie ; Lišková, Petra (advisor) ; Klímová, Aneta (referee)
The Roma are the largest and most widespread transnational ethnic community. The Czech Republic estimates their 2% representation in its population. Due to the high level of endogamy, the spectrum and frequency of hereditary diseases in the Roma population differ from the majority population. Hereditary eye diseases are one of the most common causes of blindness in younger adults and thus represent a real socio-economic burden. The aim of the thesis was to perform molecular genetic analysis in individuals of Roma origin suffering from hereditary diseases affecting vision, including dual impairments and syndromes, and to determinate the frequency of the detected pathogenic variants in this population. Molecular genetic analysis of 17 families was performed using direct and whole exome sequencing. Within the framework of an international collaboration, the degree of their mutual kinship was calculated using the PLINK program. The frequency of selected variants was determined in a control dataset comprising 156 Roma exomes and genomes. The spectrum of analyzed diseases included various retinal dystrophies, primary congenital glaucoma, Usher syndrome, neuronal ceroid lipofuscinosis, Noonan syndrome, nanophthalmos and congenital cataract, facial dysmorphism and neuropathy. The results of the thesis...

Portrayal of d/Deaf People in Cinematography
Švábová, Adéla ; Zbořilová, Radka (advisor) ; Prokšová, Hana (referee)
The bachelor's thesis analyzes the topic of deaf people and deafness in feature-length motion pictures made by hearing directors. At the beginning of this thesis the author focuses on the terminology concerning deaf people, the relationship between art and deaf people and deafness, brief history of cinematography with the accent on important events concerning deaf people and deafness and then the author focuses on influence of movies on public opinion with the accent on terms stereotype, prototype and myth. Author afterwards focuses on analysis of the selected sample of movies. There are two types of analysis in this thesis, first one looks into purpose of the topic in those movies, the second one analyzes chosen movies in detail. The second analysis ends with comparison and evaluation of those movies. The purpose of this thesis is to make first insight into the topic of deaf and deafness in feature-length motion pictures made by hearing directors.

Evaluation of postural stability among deaf adults
Palasová, Ivana ; Pavlů, Dagmar (advisor) ; Pánek, David (referee)
vi Abstract Title: Evaluation of postural stability among deaf adults Objectives: The purpose of this diploma thesis was to compare the postural stability between the deaf and the normal hearing adults, and to find out if the statistically significant difference in measured parameters does exist. Methods: 102 subjects at the age of 20-45 years participated in this study. The experimental group consisted of 35 deaf adult subjects with congenital or early childhood deafness. The control group has been made by 67 normal hearing adult subjects. The postural stability was objectively evaluated by Footscan, the pressure measuring plate. Nine tests were passed, duration of each test was 30 seconds. The total travelled way (TTW) expressing the total path the centre of acting pressure travelled during the test and the Romberg ratio, which is the ratio of TTW values under the condition of closed and open eyes, were selected as indicators of postural stability. T-test was used to assess the statistical significance of the differences between the group of deaf adults and normal hearing group. To estimate the influence of individual characteristics of the subjects (evaluating the data from the questionnaires) to their postural stability, the ordinary least squares estimator was used. Results: The experimental group was...

The difference in the character of understanding and experiencing emotions between heaving impaired users of sign language and intact people.
HEIDINGEROVÁ, Jana
The presented bachelor thesis deals with the topic of understanding and experiencing emotions of the hearing-impaired users of sign language. Describes similarities and differences in understanding emotions and emotional experience of the target group and the intact population, and within theoretical and practical parts strives to point out causes of potential differences. The theoretical part summarizes the most important influences on personality development of the hearing-impaired users of sign language and their emotional experiencing, among them e.g. nature of family environment, type of adopted communication system, specific education strategies, and different views and population attitudes towards the hearing-impaired. The empirical part includes two interviews conducted with experts on the issue of hearing impairment, and results of the color-semantic differential test, supplemented with individual expressions of emotions and stimulus words related to the topic of the thesis. Differences in the evaluation of the stimulus words and individual associations are also described. Outcomes of interviews describe similarities and differences between the target and control group, alternatively their explanation. Test results point to some differences in dissimilarity of emotional intensity, in value hierarchy of stimulus words, and in the number of discrepancies between conscious and unconscious evaluation of stimulus words. Due to the limited size of the research sample and the methods used, it is not advisable to generalize the results of this paper. The conclusions of the thesis may serve a topic for further studies.
