Suk, Rudolf ; Horák, Záboj (advisor) ; Tretera, Jiří Rajmund (referee)
Legal regulation of the provision of spiritual care for the benefit of members of the police, fire brigades and victims od crime and disasters Abstract This thesis deals with the legal regulation of the provision of spiritual care for the benefit of members of the police and fire services and victims of crime and disasters. The aim of the thesis was to analyse the legislation, treaties, as well as other legal acts currently in force in the Czech Republic, which regulate the provision of spiritual care to the above mentioned groups and, based on a comparison with other European countries, to identify theoretical models of legal regulation of the provision of spiritual care and the possibilities of their application in the implementation of spiritual care in some public institutions of the Czech Republic. The legal regulation of the provision of spiritual care to the above-mentioned groups is insufficient in the Czech Republic. Spiritual care for members of the Fire Brigade and victims of disasters is provided only externally on the basis of the personal involvement of some clergy and other entities and any legal regulation of the provision of spiritual care to victims of crimes is lacking. Concrete steps, formulated in the conclusion of the thesis, which could be taken by the Czech Republic, the Police of...

Nordic walking - gait analysis of older adults.
Novotný, Petr ; Vilímek, Miloslav (advisor) ; Horák, Zdeněk (referee)
Title: Nordic walking - analysis of senior walking Aims: This thesis aims to make a kinematic and kinetic analysis of gait and NW in elderly using Qualisys and Kistler. Afterwards, it also aims to compare the selected parameters with each other and, based on the results, to objectify the effect of NW on the gait of the elderly. Methods: The theoretical part of this thesis was processed using books and electronic sources obtained from online databases (PubMed, Medline, and Google Scholar). The research part was done in the form of an experiment. Fifteen women aged between 65 and 83 years (mean age 74) who regularly practiced Nordic walking under professional guidance participated in the research. These women were measured while walking and NW. A 3D kinematic analysis of walking and NW was performed using the Qualisys Motion Capture camera system. Ground reaction forces were measured using Kistler force plates placed in the captured kinematic analysis path. Data from these instruments was processed in Qualisys Track Manager and Microsoft Office Excel. Selected gait parameters that were analyzed included stride length, double-step length, gait speed, stride cadence, standing phase duration, lateral pelvic deviation, hip flexion and extension, knee joint flexion, dorsal and plantar flexion of the ankle...

Friction and lubrication of total hip replacement produced by 3D metal printing technology
Uhrová, Simona ; Horák, Zdeněk (referee) ; Vrbka, Martin (advisor)
This thesis investigates the tribological properties of total hip replacements manufactured by both traditional and additive technologies. The primary objective is to assess the impact of different manufacturing methods on friction and lubrication at the contact between the joint head and the acetabular cup. Techniques such as a pendulum joint simulator and optical methods are utilized to analyse the lubricant film formation and friction coefficient. The findings indicate that additively manufactured implants can potentially offer comparable or superior tribological properties compared to traditional methods, potentially leading to enhanced longevity and functionality of the implants. However, the need for appropriate surface treatment and further research into wear to ensure extended life and improved implant functionality is emphasised.

An investigation of friction and lubrication of coated hip joint replacement
Balcárek, Ondřej ; Horák, Zdeněk (referee) ; Nečas, David (advisor)
The thesis focused on studying the effects of a new hydrogel coating and material combinations on the coefficient of friction and formation of lubricating film in the conformal contact of hip joint replacement. Experiments were conducted using a ball-on-cup configuration with a hip pendulum simulator. The formation of the lubricating film was observed using fluorescence microscopy. The results showed that the application of the coating did not have a clear impact on the coefficient of friction. However, for pairs with a coated cup, there was a reduction in CoF by approximately 20%. Generally, lower friction was observed when using a ceramic joint head. Surprisingly, even more interesting results were obtained in the lubrication analysis, where the use of metal heads led to a reduction in the thickness of the lubricating layer. Ceramic pairs exhibited very stable behavior. In addition to friction and lubrication, the topography of the implants was further evaluated, and their wettability was analysed. Although the polymer coating was expected to be highly hydrophilic, the surface properties were only slightly influenced, which partly explains why there was no significant improvement in the tribological behavior of the replacement. As the coating applied is already patented and its effectiveness in reducing wear has been clearly demonstrated, it is appropriate to investigate this issue further, with more attention being paid to long-term experiments. Based on the obtained data, it appears that the short-term benefits of the coating are practically negligible. However, it is important to highlight that, except for minor exceptions, the application of the coating did not lead to a deterioration of properties, which is a significant outcome of this work.

An investigation of lubrication of knee joint replacement
Sýkora, Tomáš ; Horák, Zdeněk (referee) ; Nečas, David (advisor)
This diploma thesis deals with an experimental analysis of knee joint replacement lubrication. The experiments were realized at a knee joint simulator which can apply conditions according to certain standard and survey the phenomena by using fluorescence microscopy. The aim of thesis is to clarify the influence of particular components of synovial fluid on the lubrication process. The intensity of fluorescence expresses dimensionless parameter of a lubrication film thickness. There was a fundamental study with mineral oils before the experiments with the synovial fluid. The study allows to have a look at contact transformation during walk. Results are shown in graphs as dependency of intensity on time, including pictures showing phenomena in the contact zone. Experiment results show that protein -globulin creates a layer on the surface. There is albumin on the layer and it makes the lubricating film thicker. The protein interaction is supported by hyaluronic acid and fosfolipids which stabilizes the created structure. According to lubrication is behaviour of film related to a complex structure of synovial fluid. Thesis gives more information about behaviour of synovial fluid and can be used for future development of knee replacements.

Development of the coefficient of friction and lubrication film in a total knee replacement during a gait cycle
Odehnal, Lukáš ; Horák, Zdeněk (referee) ; Ranuša, Matúš (advisor)
This master´s thesis deals with the experimental analysis of the coefficient of friction and lubrication film in total knee replacement. The experiments are performed on a knee joint simulator, with an implemented module for measuring friction. To observe film formation, fluorescent microscopy is used. The experiments are mainly focused on a detailed description of the influence of parameters occurring during the gait cycle. This approach should significantly help in describing the tribological processes that occur in the total knee replacement. The results confirm previous investigations in terms of axial load, where the coefficient of friction decreases with the increasing load. In the case of lubrication film, no significant changes are observed. On the contrary, while investigating the influence of SRR, noticeable changes in film formation are observed while the coefficient of friction being unaffected. While describing the whole gait cycle, precise results are obtained only in the first half of the cycle as the second half is accompanied by the occurrence of large deviations from a rapid decrease of load. This work provides a better understanding of the field of lubrication film in total knee replacements. Moreover, thanks to the simultaneous measurement of the coefficient of friction and the observation of the contact area, it is possible to draw better conclusions than if the experiments had been carried out separately.

Influence of viscosupplementation on cartilage lubrication
Ondra, Martin ; Horák, Zdeněk (referee) ; Ranuša, Matúš (advisor)
This work deal with the determination of the effect of viscosupplementation on the lubrication of articular cartilage in the beginning phase of osteoarthritis. This effect was evaluated based on the development of CoF measured by a tribometer in configuration pin-on-plate. The tribological model of incipient osteoarthritis was simulated by using two articular cartilages lubricated with osteoarthritic synovial fluid to which viscosupplementation agents were added. These preparations differed mainly in cross-linking and molecular weight of hyaluronic acid (HA). Measurements have shown that viscosupplementation may be effective in the beginning phase of osteoarthritis. The efficacy of viscosupplementation preparations with cross-linking HA was significantly higher compared to the efficacy of viscosupplementation preparations without cross-linking. These results support the use of viscosupplementation to delay the advanced stage of osteoarthritis.

Lubrication of knee joint replacement
Sadecká, Kateřina ; Horák, Zdeněk (referee) ; Vrbka, Martin (advisor)
The work deals with the lubrication of total knee replacement using fluorescence microscopy method, which allows unique insight into the contact between femoral and tibial component. The aim was to determine the effect of composition of synovial fluid (i.e. albumin, -globulin, hyaluronic acid and phospholipids) on film thickness and protein behaviour in contact, and also to determine changes of contact area during rotation. Since this is the first experimental work dealing with a knee replacement lubrication primarily, only simple rotation and load cycles were applied by the knee simulator. The output of the experiments was fluorescence intensity, which corresponds to dimensionless film thickness, over time. Another important output are the images directly showing the fluorescently labelled proteins in the contact area. The results show, there are fundamental differences in lubrication in different positions of rotation, due to changes of position, shape and behaviour of the contact area. The composition of the lubricant is also essential, since the proteins themselves form a relatively strong lubricating film and their mixture leads to a substantial reduction of film thickness, due to significant formation of clusters. Complex fluid, although it does not form the strongest layer, is able to create a quite continuous film.
