Manufacturing of swivel pin
Vávra, Roman ; Šlais, Miroslav (referee) ; Řiháček, Jan (advisor)
The thesis deals with the design of a suitable technology for serial production of a pin. The component material is structural steel 11,320 5R. Due to the series production and material savings, the molding technology was chosen to be cold. For production, the CM 4-5 ECO HATEBUR process press was designed with a nominal force of 1 700 kN. Progressive tool and drawing documentation of tools for the final operation were also designed. The tool load was verified by manual calculation, and the finite element method was calculated to heat the formed blank due to molding.

Evaluation of upsetting test
Vávra, Roman ; Císařová, Michaela (referee) ; Řiháček, Jan (advisor)
This work is focused on theoretical and practical processing upsetting test. There is an explanation of their significance in engineering. Also, there are described various kinds of tests and their evaluation. Furthermore, the work deals with the experiment for a specified material MS 68. This material was compacted using two test machines equipped with measuring software. First machine is a hydraulic press CZR 600 with software DEWESoft and the second is a universal testing machine ZD 40 using software M-Test. An evaluation based on the collected data is included in the form of deformation resistance curves of tested material.

Divorce/breakup of parents from the point of view of adolescents
VÁVRA, Roman
The theoretical level of the divorce theme is based on specialized literature and other sources of information. In the theoretical part are defined the basic terms related to topics such as family, function of family, types of education, OSPOD activity, court activity, child's right of participation, etc. The data for the empirical part are obtained by semi-structured interview and processed qualitatively. The interviews were conducted with seven adolescents between the ages of 18 and 19 who have personal experience with the divorce/breakup of their parents. The aim of this thesis is to get an idea of how adolescents retrospectively perceive pass divorce/breakup of parents, with a time interval of 2-5 years. According to my finding, it has clearly emerged that family breakdown is a very demanding life situation for all involved, which brings about a lot of different changes. These changes are emerging in three basic categories that came from the data analysis (functional and dysfunctional family, divorce factors, fast loss of childhood and "adult" reconciliation).

Family Life with a Handicapped Child
VÁVRA, Roman
This Bachelor´s thesis is focused on the issue of living in a family with a handicapped child not only from the emotional but also social, financial and other points of view. The Bachelor´s thesis is divided into theoretical and empirical parts. The theoretical part consists of five chapters. The first chapter defines and determines family as a unit, describes the basic functions of a family as perceived and defined by various specialists. The second chapter describes responses of parents to a newborn child with the disability and also causes of incurrence of such disability and possibly existing types, such as physical disability, mental disability, visual impairment, hearing and combined impairments or disorders are analyzed. Further, this chapter presents the individual stages of response to an announcement of a serious diagnosis where the parents go through various phases, i.e. shock and denial phase, helplessness phase, gradual adaptation and dealing with the problem phase, bargaining phase, and realistic attitude phase. Then, it analyses the factors that can influence acceptation of the handicapped child and possible inappropriate educative approaches of the parents to the handicapped children as described by various specialists. The third chapter is dedicated to the sibling relationship. The fourth chapter is focused on economic factors in the family with the handicapped child. And the last chapter introduces social services for the families with the handicapped child. In the empiric part a main goal is set which is to find out how the parents experience the stress connected with the handicapped child from the emotional and social as well financial point of view, etc. There are also two research questions put arising from the goal of the research. The first question leads to the revelation of an actual financial situation in a family with the handicapped child and the second question of the research is what view of future mother or father who care for the handicapped child actually has. To achieve the research goal of this Bachelor´s thesis a qualitative research strategy has been chosen. The basic method used is questioning, semi-structural interview. The interviews were conducted with five families caring for their handicapped child. There were five mothers and one father, a husband of one of the mothers, who agreed with the interview as the only man. Communication partners were selected on the basis of a purposeful selection. The interviews were held in natural environment of the communication partners upon their agreement. Qualitative research investigation has discovered the surprising finding that all of the communication partners got insufficient information about their child´s diagnosis from the doctors specialists. The specialists were quite unfeeling, asking them whether they would rather wish to place the child in a specialized institution. The parents searched for information about their child´s diagnosis in professional journals and books, later on internet. Another unpleasant finding is that the state financing (state benefits) of the families with the handicapped child is insufficient. Moreover, the research discovered that the sibling bond plays a substantial role in the care for the handicapped child since the siblings participate in the care and provide assistance and support for the handicapped child. In the families with siblings the functioning of the whole family is affected positively.
