Development of finite element model of human vocal tract and space around the head based on data from computer tomography
Švarc, Martin ; Pellant, Karel (referee) ; Švancara, Pavel (advisor)
This bachelor´s thesis deals with creating a computational model for acoustic wave propagation in vocal tract and the area near the head. The main objective of this work is to map the three-dimensional model of the human head as an additional acoustic environment for more accurate measurement of the human voice on the basis of data from computed tomography, the study of function of the vocal cords, biomechanics of the human voice and an overview of medical imaging techniques suitable for the display of biomechanical models. The grid for finite element method (FEM) will be created from solid geometry of the vocal tract (from the vocal cords to the lips) and the acoustic space near the human head. The grid will be created in order to obtain new knowledge about the different locations of a human head with microphone.

Possibilities of physiotherapy for functional disorders caused by vocal loading in singers
BÁRTOVÁ, Kateřina
This bachelor thesis is focused on the possibilities of physiotherapy for functional disorders from excessive vocal load in singers. Functional disorders caused by excessive vocal load are a very common, but also neglected issue of voice. These disorders are caused by a frequent overuse of the vocal cords by speech and singing voice, mainly due to a poor voice technique. Functional voice disorders occur in voices of the untrained, but also in voices of the profesionals. If vocal overload is not treated, phonaesthenia, hyperkinetic dysphonia or hypokinetic dysphonia may occur. If the patient is not getting treated even in this case, irreversible organic changes in their vocal system may occur. In functional vocal disorders, there is a dyscoordination of different parts of the vocal tract, hyperactivity of the exhalatory muscles, extra-laryngeal muscles, and vocal cord adductors. The treatment of functional disorders from excessive vocal load consists in the elimination of the primary causes. Re-education of the voice with the help of voice exercise and re-education of the related body system is important. The aim of this paperis to map the possibilities of physiotherapy for functional disorders from excessive vocal load in singers and to design an exercise unit as a prevention of functional vocal disorders. In the theoretical part, the bachelor thesis deals with the voice, the anatomy of the vocal system and its function. There are described functional voice disorders, their causes, and methods of treatment. Furthermore, the bachelor's thesis focuses on the description of physiotherapy options that can be used for functional disorders from excessive vocal load. The practical part of the bachelor thesis is divided into two parts. The first part is processed in the form of qualitative research. The research sample consists of two singers with repeated problems of overloaded vocal cords. The sample underwent an input and output kinesiological analysis and the design of the therapy was created according to the identified issues. The therapy had positive impact on both patients and helped their improvement. The second part is processed in quantitative form. The research sample consists of 100 amateur and professional singers who filled out a questionnaire focused on the education of respondents in the field of singing, their subjective opinion on the correct performance of singing, questions on vocal disorders and methods of their treatment. The questionnaire contains, as well, a short subjective test of vocal overload. The questionnaire maps singers' awareness and the incidence of vocal disorders among those surveyed. According to the results of the questionnaire, it can be stated that the education of singers is still insufficient. In accordance with the results of the questionnaire, a handbook for singers was compiled in order to prevent voice disorders with the help of prevention and to inform singers about functional voice disorders.

Influence of airflow control with vocal cords on dynamic stand stabilization
Rybáčková, Kristýna ; Šorfová, Monika (advisor) ; Lopot, František (referee)
Title: The effect of airway control on stance dynamic stability Objectives: The aim of this thesis is to find out whether and how will the influence of vocal cords modulation be manifested on the dynamic stabilization of the standing body during translational shifts of the supporting surface of different intensities and A-P directions. Thus, building on the findings of Massery et al (2013). Methods: The thesis has the character of qualitative research. The experiment was attended by 23 healthy probands, of which 7 men and 16 women aged 20-40 years. Spirometry was used to test the objectivity of airway airflow during breathing / phoning maneuvers with different vocal cords positioning and dynamic computer posturography using the Neurocom Smart Equi Test System and its Motor Control Test, which evaluated the effectiveness of automatic postural responses. We connected the posturograph with the spirometer using the Kistler accelerometer (type 8766A100BB). The course of the experiment was simultaneously recorded by a camera (GoPro Hero 7). The Smart EquiTest System generated three postural perturbations of different intensity (S - sub treshold, M - threshold, L - saturating) in two directions (anterior translation / posterior translation). The measured data were then processed in the program Neurocom...

Nursing caring for a patient with thyroid gland disease
Drnek, Jan ; Pírková, Vendula (advisor) ; Kulhavá, Miluše (referee)
This bachelor's thesis "Nursing care for female patient with thyroid disease" consists of two parts describing theory and practise. Theoretic part provides basic information about thyroid gland - anatomy, histology and physiology - function in human organism, followed by description of goitre, the most frequent disease requiring surgical intervention, focused on disorder reasons, incidence symptoms, diagnostics, therapy, possible complications and prognosis for patients suffering this disease. Part of the literary researche describes the nursing care process for patient with planned neck surgery, and the role of the nurse in pre- operative preparation and a post-operation care. Practical part presents a case story of 53 years old female patient from diagnosis to definitive surgical solution. Case story has been described according to the Marjorie Gordon nursing modus, which accentuates biologic and social needs of the client. After presentation of basic data on patient, diagnostics and therapy of her disease and hospitalisation course, the story has been focused on specific needs of the client, formulation of nursing diagnoses, targets and plans, their realisation and evaluation. The aim of this thesis was description of question is in surgically intervented thyroideal disease focused on nursing...

Speech education of a free time educationist - the vocal cords, a work tool
PRAŽÁKOVÁ, Magda
Speech education of a free time educationist the vocal cords, a work tool. The work concerns with the anatomy of speaking organs, genesis and evolution of the voice and its properties. It deals with defects of voice, in terms of functional and organic. The voice education is divided into the individual components respiratory, vocal (phonetic) and articulatory. In the context of prevention of voice defects it emphasizes the voice hygiene, not only in teaching of the correct voice techniques, but t also in recovery after the voice organs diseases. An important part of this thesis are games and exercises for pedagogy of leisure time, where we can find illustrative and detailed examplex of not only relaxing games such as a rag doll or a worm, but also the breathing exercises for relaxation of the body and the achievement of correct breathing (e.g. drawing with the blowing through a straw or various stretching exercises). Therefore it may be a source of inspiration not only for a person potentially interested in a voice training, but also for educationists of free time.

Voice/vocal cords - the working tools of a leisure time pedagogue
ČARNOGURSKÁ, Lenka
This work deals with voice and the vocal cords as the working tools of pedagogues not only of leisure time. It describes the structure and the workings of the vocal apparatus. It discusses voice typology and voice properties. It includes the basic division of voice disorders and speech impediments, their causes, and the possible ways of their treatment. It also summarises the principles of vocal hygiene along with the voice care options available. The crucial part of the work is the chapter concerning vocal practice, which gives information on specific breathing, vocal, and articulation exercises. Pedagogues belong among vocal professionals and are subjected to considerable vocal strain. Correct voice formation and care should be part of their lifestyle. At the same time, pedagogues are speech models to their pupils and students, and refined speech reflects on them.
