The Sensor Systems Design and Optimization for Energy Harvesting Applications
Žák, Jaromír ; Husák, Miroslav (referee) ; Bajer, Arnošt (referee) ; Hubálek, Jaromír (advisor)
Dissertation thesis is focused on using alternative energy sources called energy harvesting. This thesis offers a solution to problems with autonomous powering of sensor networks if primary power source recovery is impossible. In these cases, energy of the external power (e.g. temperature, light, motion) should be used. Proposed solution should be especially used in the field of medical applications (e.g. cochlear implants, pacemakers, insulin pumps). Long time monitoring of the personal health status is also possible when employing automated sensor systems. In this work, there is state of art review relating to the low power energy sources for an alternative powering of sensor systems. It was observed that existing systems are almost prepared for the implementation of energy harvesting power sources. The energy harvesting power sources have been developed by numerous researcher teams around the world, but there are only a few variants of power management circuits for effective energy gaining, storing and using. This area has a huge potential for the next research. The issues regarding to the distribution of gained energy are solved on the complex level in the thesis. For these purposes, a new simulation model of the whole system (fully implantable artificial cochlea) including its subcircuits was developed in the SPICE environment. It connects independent subcircuits into a single comprehensive model. Using this model, a few novel principles for energy distribution (e.g. Charge Push Through technique) was developed. In the near future, these techniques are also applicable to the design of versatile sensor systems.

Cooperation of a kindergarten teacher with other experts when working with a child with a cochlear implant
VÁCHOVÁ, Anežka
The bachelor thesis deals with the issue of education of children with cochlear implants in a regular kindergarten class. The main aim is to find out how the cooperation between the kindergarten and the specialist departments takes place and whether this cooperation is sufficient for the overall development of the child after cochlear implantation. The theoretical part is developed in four chapters, which include basic concepts, definitions, aetiology, developmental peculiarities of preschool children with hearing impairment and the legislative framework. In the first chapter I discuss hearing impairment, in the second chapter I discuss the characteristics of preschool and the specific peculiarities of this period. Chapter three discusses the legislative framework and the final chapter focuses on the possibilities of educating a preschool child with a hearing impairment in kindergarten. In the practical part, a questionnaire is developed, which I asked the teaching staff of regular kindergartens who have experience with inclusive education of a child with a cochlear implant to fill in. The questionnaire survey with the results is elaborated in the practical part of the bachelor thesis. It was conducted electronically for three weeks.

Caring for a child with a cochlear implant in the home environment.
LOVĚTÍNSKÁ, Michala
Cochlear implants have been used in the Czech Republic since 1993. The cochlear implant gives deaf individuals the opportunity to receive auditory sensations. Cochlear implantation is a procedure where the implant is inserted under the skin and connected to a series of electrodes that are inserted into the cochlea. This procedure is performed by a surgeon which is specializes in ear, nose and throat. After long - term rehabilitation, the individual is able to understand spoken language and can even make phone calls without reading. With a cochlear implant, most users canintegrate into main stream society, among the normal hearing population. Children go to mainstream school, play sports, and communicate with others, all with out the use of sign language. Cochlear implants are currently operated in the Czech Republic at the Motol Hospital in Prague, the St. Anne's Hospital in Brno and the Ostrava Hospital. The first aim was to find out and describe how the child experiences the cochlear implant fitting, the second aim was to find out what problems parents perceive after fitting the cochlear implant in a child, and the third aim was to find out what barriers parents perceive in caring for a child with cochlear implant. The research investigation was carried out by qualitative research, using the method of semi-structured interview. The research sample consisted of ten adult informants, specifically parents, and five child informants. Parents and children come from different regions of the Czech Republic. The interviews took place from February to March 2023. Subsequently, all responses from the interviews with parents of children with cochlear implants users were listed. The results of the responses are divided into categories and their subcategories. The analysis of the results shows that the perception of the cochlear implant is different in children. The research found a fourth group of children who react to the first programming by crying. It was found that the child's experience of CI programming can be influenced by parents. As such, barriers to caring for a child with a cochlear implant have not been identified. Rather, parents perceived shortcomings of the cochlear implant, such as the speech processor slipping off the child's head, difficulty in obtaining a helmet, and perceived sweat as a deficiency with CI. The results show that children's perception of cochlear implant fitting is very individual, depending on many factors. Parents can influence the child's perception by training individual sounds in the home environment. Problems following cochlear implant programming in a child should be minimal, with a chech-up by a clinical engineer. The difficulties perceived by parents in caring for a child with a cochlear implant do not come out as prominently as CI deficiencies. It is very important to treat the child individually. Each child has different characteristics and abilities. From the results of the research investigation, we want to provide comprehensive information for parents of children who experience hearing loss or deafness in their child, and their possible solution is a cochlear implant. The results of the bachelor thesis were presented before an expert jury at the student competition of the ZSF JČU in České Budějovice. Furthermore, the results will be published in a professional journal for nurses.

The inclusion of the child with a cochlear implant in the preschool mainstream education
SAJTLOVÁ, Tereza
This bachelor thesis deals with the problem of inclusion, concretely focused on a child with a cochlear implant in a kindergarten of a mainstream education. The target of this thesis is to make a theoretical basis of children with a cochlear implant problematic related to their education and on this basis make a case study of a child with a cochlear implant in a kindergarten of a mainstream education in an evaluation accent of an education process. The thesis is devided into two parts, theoretical and practical. The theoretical part is in its first chapter focused on an area of hearing impairment, defines the basic concepts and describes the specifics of children with a cochlear implant. The second chapter contains the basic terms and knowledges of a cochlear implant. The third and also the last chapter of a theoretical part deals with preschool education in a relation to the hearing impairment. The practical part focuses on a description of a development of the boy in all areas with a bigger focus on communicative competention and a process of preschool education. Also points to the separate support measures and their usage by his integration to the mainstream education. For the filling of this targets was being applied a research which took the form of observation, halfstructurated dialogues and document analysis. Due to entirety complexity the dialogues with the parents and the kindergarten teachers and anamnestic data has been detailed. By the research investigation it has been found out that the choice of a child placement to the mainstream education doesn´t have to be the suitable variant because every child is unique and has its own needs and limits. Through the detail analysis has been found out that the inclusion is very individual matter conditioned by many factors. Due to the relation to this mentioned boy with a cochlear implant there are these: a rehabilitation success, the level of communication skills, the correct choice of communicative system, the impact of hearing impairment to the separate parts of the development ant the last but not the least the cooperation of the parents and the preschool facility.

Comprehensive care for a child with severe hearing impairment before and after cochlear implantation
Lonsmínová, Lenka ; Hádková, Kateřina (advisor) ; Bartoňová, Miroslava (referee)
The thesis deals with the process of cochlear implantation from diagnosis of hearing impairment to sound processor setup and hearing rehabilitation. In the theoretical part, attention is paid to defining the topic of hearing impairment, there are mentioned means of communication that can be chosen for communication with a child with hearing impairment, and we find a description of the development of spoken language in these children. Subsequently, attention is paid to the system of care for these children and finally the cochlear implant and the whole process of cochlear implantation is described here. The empirical part is based on interviews with mothers of children with severe hearing impairment who underwent cochlear implantation, and focuses primarily on informing parents about the whole process, establishing communication with the child before implantation and the course of subsequent hearing rehabilitation. The work aims to point out the need for early diagnosis of hearing loss, its correct compensation, establishing contact using a sensory accessible means of communication and the importance of long-term cooperation in setting up a sound processor and subsequent hearing rehabilitation. Another goal is to prepare material that will quickly and easily provide parents with basic information...
