Measuring the burden of caring for the elderly
Mezenský, Štěpán ; Remr, Jiří (advisor) ; Tuček, Milan (referee)
This thesis focuses on informal care and the burden of informal care. The aim is to explore the current form of informal care and to reflect on it with existing knowledge. In its first part, the thesis focuses on a description of the demographic development of the seniors, a description of informal care and the problems associated with it, solidarity, caregiving burden, and the possibilities of assistance and support for informal caregivers. Furthermore, the thesis sets out to describe what assistive technologies are, how informal carers use them and how they relieve them of the caring burden. Peripherally, the thesis also touches on the impact of the COVID-19 pandemic on the caregiving burden. Through quantitative measurement using my own modification of the ZBI-4 questionnaire, I describe caregiving burden, taking into account basic sociodemographic data. The results show no statistically significant differences either across genders or across generations, apart from a significantly lower perceived caregiving burden for Generation X. I follow the quantitative part of the research with the qualitative part, based on semi-structured interviews. In the qualitative part, I describe the reasons for the decision for informal caregiving, its form and consequences, potential generational differences,...

Eye-Tracking Control of an Adjustable Bed
Kopeček, Martin ; Kremláček, Jan (advisor) ; Čapek, Lukáš (referee) ; Komzák, Martin (referee)
The origin of this work was based on the need to control an electric positioning bed by patients with no or significantly reduced upper limb motor skills. The key point and objective of the dissertation study was to develop non-contact alternatives to manual controls and to verify that the eye-tracking technique is usable and offers patients a new level of increased self-sufficiency. The thesis is organized into three related parts with experiments conducted at the detached departments and in the laboratory. After an introductory section covering the stages of development and current progressive trends in eye movement tracking, an experimental study of the applicability of bed control with the role of alternating head and leg position changes using on-screen graphical controls is described. This stage was conducted using a virtual bed. In a group of 17 patients with diagnoses of a pentaplegia, tetraplegia, high paraplegia, myopathy, and spinal muscular atrophy, the overall time to solve the task was 67.1 s (median) with a large interindividual variability with interquartile range from 56.7 s to 92.9 s. The solution efficiency (100 % matched to optimal performance) was 45.5 (34.9; 62.0) %. Within each group patients achieved different results for both studied parameters. When evaluating the features of the...

Current Trends in Business Practice Support Employees with Visual Impairment.
KUBEŠOVÁ, Eliška
The bachelor's thesis deals with people who are visually impaired and with current trends in support during their employment. The thesis aims at the analysis of the needs of people with visual impairments in connection with the issue of their employment, as employment and access to the labor market belong to basic human and civil right. People with visual impairments are limited in their access to information and independent mobility. The area of occupational rehabilitation, re-education, development of information and communication technologies, precisely these areas aim at the minimization and elimination of limits. At the beginning, the theoretical part describes who a person with a visual impairment is, and deals with the degrees and types of visual impairment. It analyses the specifications of congenital and acquired visual impairment, the possibilities of its compensation and, last but not least, its health and social impacts. Another section was dedicated to methods of education and professional training of people with visual impairments. In these sub-chapters, individual types of education are briefly explained, from pre-school, primary school and secondary school to university education and subsequent professional training. The last section of the theoretical part describes the work itself and also its importance for individuals with visual impairments. The sub-chapters of this section are devoted to the psychological aspects of work, legislative definition, human rights issues and of course to current trends in the employment of visually impaired people. The practical part is processed in the form of quantitative research. The data obtained from the survey are processed at the level of the first and the second level of classification. The results show that visually impaired people encounter most often a certain attitude of employers and employees based on prejudices against people with disabilities, with employers' fear of higher expenses when employing them. On the contrary, they perceive the most significant support from the family, the possibilities of using modern technologies, or assistive technologies, and in projects supporting the employability of the blind people.

Rejmanová, Alžběta ; Nováková, Olga (advisor) ; Svěcená, Kateřina (referee)
This thesis aims is designing and practical testing of "small splints" by patients which have limited functionc of upper extremities due to damage or malfunction. The proposed "small splints" are designed to facilitate the completion of certain procedures of pADL. "Small splints" are made from thermoplastic material, which is convinient for such purposes as regards the properties of ductility, variability and customization options. This bachelor thesis presents proposals of "small splints" for personal hygiene, specifically for a toothbrush and self - feeding, with selected objects: a glass, a cutlery knife, a fork and a spoon. The last "small splint" is intended to graphomotoric with a specific focus on stationery. The work is divided into two parts, theoretical and practical. The theoretical part is based on the analysis of scientific literature and deals with general functions of the upper limbs and causes of limited functions, splinting and assistive technology options. The practical part contains the research methodology, my target and formulation of research question. Three patients with limited function of upper limb were involved in the project. These patiens tried splints over a period of time and "small splints" were modified according to their individual needs. According to the...
