A comparison of different types of epoxy adhesives
Mihulka, Jan ; Žák, Ladislav (referee) ; Kubíček, Jaroslav (advisor)
This thesis is focused on a bonding technology. The first part describes the theory of the bonding and it is discussed the main areas of this technology. The experimental part deals with the comparison of four two-component epoxy adhesives in terms of shear strength. For the experiment it had been selected adhesives: Bison Epoxy Universal, Pattex Repair Epoxy Ultra Strong 5 min, Ergo 7430 and Letoxit LH 232. After performing the experiment, it was shown that Bison Epoxy Universal and Pattex Repair Epoxy Ultra Strong 5 min achieved the strengths stated in the datasheet. The strengths of Ergo 7430 and Letoxit LH 232 adhesives was lower than stated in their technological products, thefore, did not meet our expectations. The reason for not achieving the declared strength was probably poor dosing or insufficient mixing of ingredients.

The relation between the early mother-child contact after birth and the subjective perception of their relationship
Kolumpková, Michaela ; Horáková Hoskovcová, Simona (advisor) ; Takács, Lea (referee)
This work observes the relation between mother-child early contact immediately after birth and emotional tune of mothers in relation to their child. The theoretical part deals with the situation of labor, further development after birth, with an emphasis on very early contact and ways to establish the relationship between a mother and a child. In the end of the theoretical part, the quality of the relationship between a mother and a child and the interactions between them is described. The empirical part examines if the early contact immediately after birth or a general contact between mothers and babies in the hospital, influence emotional tune of a mother to her child. The research was based on interviews with mothers who were describing their child. It was assumed that the emotional tune of mothers is associated with the choice of adjectives describing their child or the whole situation. However, research does not show a significant relation of early contact and emotional tune of a mother to her child. Based on the research results, the conclusion is that the immediate early contact after birth does not have a significant effect on the quality of the relationship between a mother and her child.

Virtual launch of the robotic welding and gluing line using Tecnomatix - Process Simulate
Tomeček, Radim ; Juříček, Martin (referee) ; Simeonov, Simeon (advisor)
This thesis deals with the design and creation of a virtual twin of a robotic cell intended to simulate and create a virtual launch of this cell. The goal was to design the layout of the robotic cell and subsequently create a full virtual run of an automated robotic workstation designed for spot welding, MIG welding and bonding processes. The initial research section deals with the individual technologies to be simulated. Subsequently, three designs for the layout of the robotic workstation are developed in this thesis. After evaluating and selecting the design, a virtual twin of the robotic cell is created using Process Simulate and then all the processes are simulated resulting in the virtual launch of the cell.

Current trends in the care of newborns.
MARKOVÁ, Anna
Neonatology is a branch of medicine that still evolves. Therefore, it is necessary to adjust some experienced, obsolete or even dangerous procedures so as to find current care options that will suit either current medicine or current society. The thesis aims both to verify the newborn care development in a period of the last twenty years and to primarily map the actual situation. The diploma thesis is divided into two parts, theoretical and practical. The theoretical part of the work deals with current obstetrics and clarifies individual areas of newborn care. The practical part presents the results obtained using a qualitative research survey, having two goals delineated. The first goal focuses on mapping changes occurring in the newborn care in the past twenty years. The second goal aims to realize possible benefits of alterations to mother and child. To obtain data, two sets of framework questions were set. One questionnaire was determined for nurses and midwives who had at least ten years' experience in taking care for the newborn and the other for mothers where it was at least a five-year- gap between the first and last delivery. The research survey shows that over the years there have been changes in all areas of newborn care that we monitor. In the first treatment of the newborn after birth, in the initiation of nutrition, bath, care of the umbilical stump, in the childbirth management and other necessary procedures where the needs of the child and the mother's wishes must merge. Personnel' knowledge and procedures in individual facilities also play an important role, which should correspond with current recommendations. Information obtained from the research survey could be used to think about possibilities how to make the work of nurses and midwives more efficient and it could be used to improve the quality of nursing care.

Mother-infant bonding - a historical comparison
Slezáková, Zdeňka ; Dudová, Radka (advisor) ; Šmídová, Olga (referee)
Bonding is an emotional and biological process that creates a bond between a mother and her child and is among others important for easier breastfeeding, faster recovery of the mother etc. It is important to support it by an early contact between the mother and her newborn child. The diploma thesis aims to compare the discourse regarding mother-infant bonding and its support in our country around the year of 1980, when the rooming-in system appears, up to the present, with the milestone between 1998 and 2000, when the Centre of Active Birth was established as a result of changes in birth care that occurred then and which started to offer a different kind of care from the model that was known and used in the Czech Republic at that time. Emphasis will be put on the development of the discourse, changes in birth and after-birth care it has brought and changes of its participants and the role which women have as receivers of care. The theoretic part introduces the relatively little-known term 'bonding' and its support from the biological and social points of view, then discourse analysis will be applied in the methodological and experimental parts of the thesis. Analysed materials included media communication both in printed and electronic forms available at each analysed period. Keywords:...
