The comparison of the effect of passive hanging and hand grip strengthener ring compression on grip strength, postural function and range of motion in a healthy active population: a randomized experimental study
Haňurová, Adéla ; Čejka, František (advisor) ; Iskendri, Darina (referee)
Grip strength is increasingly used as a bioindicator of quality of life in both older and younger population. That's why we decided to research methods for increasing grip strength. The first method involves using resistance rings for grip strength training, while the second method involves passive hanging. The aim of this study was to investigate two methods for training grip strength and compare their effects on the physiological parameters of the human body after a month of systematic involvement in the daily lives of study participants, with the goal of determining their potential for rehabilitation. Participants were healthy, active, recreational athletes aged 20-60 years. They were stratified and randomly divided into two groups: one trained with resistance rings, and the other was passive hanging. Training sessions lasted 7 minutes each day, and the study duration was 1 month. Input and output measurements included examination of ranges of motion in the shoulders and spine, evaluation of postural functions and grip strength assessment using a dynamometer. A total of 31 participants completed the study, with an average age of 40.7 years, including 15 women and 16 men. Most participants were right-handed, with only one left-handed and two ambidextrous individuals. Statistical analysis revealed...

Surgery Treatment in Advanced Osteoarthritis of the Thumb CMC Joint Abstract The thesis addresses therapy of advanced stages of degeneration of the first carpometacarpal joint. First carpometacarpal joint is crucial for thumb oposition, allowing for a grip and fine motor skills. Based on standardized examination methods and criteria of thumbs` range of motion, grip strength - as described in experiment of this work - functional evaluation, overal patients` satisfactory rate and pain evaluation, this work compares the most frequently used surgical methods in treatment of 3rd and 4th degree of first carpometacarpal joint osteoarthritis. Arthrodesis, which provides good stability and thumb strength, however, range of motion is and fine motor skills are deteriorated. Resection arthroplasty, a wide group of surgical techniques based on trapeziectomy, where - despite the performance of tendon interposition, tendon sling or even ligament reconstruction - a grip strength loss, stability of the grip deterioration and restriction of thumb range of motion is inevitable. The last group of arthroplasty using implants, either replacing trapesium after it`s resection or total joint arthroplasty of the first carpometacarpal joint, which preserve both first column height and a center of rotation. Aim of this thesis is to...

Design of semiactive rear damper for electrobikes
Uhlíř, Radim ; Růžička, Bronislav (referee) ; Strecker, Zbyněk (advisor)
When riding off-road motorcycle, the rider's comfort and the grip of the driven wheel are crucial factors. That is why efforts are constantly being made to develop better shock absorbers that provide better comfort and rideability. Semi-actively controlled magnetorheological dampers can provide a significant improvement in vibroisolation properties. The aim of this thesis was to design, manufacture and test a fast magnetorheological damper for the rear structure of the Kuberg Freerider off-road electric motorcycle. The design damping characteristics were based on those of the factory DNM Burner RCP-2S damper. The magnetic circuit of the damper was designed using magnetostatic FEM analysis and the time response of the piston group was verified using transient electromagnetic FEM analysis. Subsequently, structural analysis of selected parts was performed, and the damper was fabricated and tested. A function sample of the magnetorheological damper with a 240 mm pitch, 76 mm stroke, dynamic range of 9.1 at a piston velocity of 0.1 m/s and an average time response of 6.6 ms has been created.

Kiselev, Danila ; Pavlík, Jan (referee) ; Vetiška, Jan (advisor)
This bachelor thesis focuses on the conceptual design of a universal end effector for handling shape complex components. The first part of this thesis focuses on a detailed research in the field of end-effectors especially manipulation end-effectors with a detailed description of their subsets. The next section is a system analysis that defines the problem situation and searches for an optimal solution. This is followed by an end effector design section that describes the individual components and the resulting assembly. The component descriptions include technical parameters. To verify functionality, a check calculation of the required gripping force was performed. Based on the results, a working head was selected. The critical moments are checked and compared to the manufacturer's maximum values, confirming the functionality of the proposed concept. At the end of the paper, in the evaluation and discussion chapter, other design options and their advantages and disadvantages in relation to the conceptual option are discussed. 3D models and manufacturing documentation of the individual components and assemblies have been developed.

Design of end effectors for forgings handling in an automated line
Pazour, Jiří ; Pavlík, Jan (referee) ; Tůma, Zdeněk (advisor)
The thesis deals with the design of four end effectors for forgings handling in an automated forging line. After a systematic analysis and determination of important variables, three conceptual variants of effectors were proposed, from which the best one was selected by means of multicriteria analysis. The parallel gripper variant was selected as the best one, for which the jaw shapes were designed and the required gripping force was calculated. According to the required stroke per jaw and force, the parallel gripper PGN-plus-P 300-1-V was selected, for which sensors, fittings, hoses, guards and valves were chosen. Furthermore, the manufactured parts, e.g. guards and flanges, were designed. The final design was verified by calculations for the maximum load of the gripper and the industrial robot. Last but not least, the total purchase price of the four effectors was estimated at CZK 620,000. This amount did not include the costs of assembly and the profit on sale.

Self-defense for medical staff of the Emergency Medical Service of the South Bohemian Region
ZELENKOVÁ, Iva
The subject of the bachelor's thesis is "Self-Defense for Medical Staff of the Medical Rescue Service of the South Bohemian Region." This work explores the various possibilities of self-defense - both physical and verbal - applicable to the disabling the aggressor. The theoretical part is focused on the current state of attacking exit crews. It also includes training of medical rescueworkers, including cooperation with the Police of the Czech Republic, as well as some factors that can greatly endanger healthcare professionals in their work. In the theoretical part, both the basics of self-defense - verbal and physical are mentioned, including the procedure of simple defensive techniques, for example against kicks, grips or strangulation. If an attack cannot be nullified by self-defense, we have a number of defenses, usable against the aggressor. Such a solution to the conflict also carries many risks in the area of criminal law, which is why the last chapter of the theoretical section is devoted to legal legislation. The data to process the practical part was obtained in the form of qualitative research using a semi-structured interview method with 10 employees of the Medical Rescue Service of the South Bohemian Region. We investigated whether they had experience of verbal or physical assault, how they prepared for possible assault, and whether they had any self-defense means by which to avert imminent attack in the course of their profession. The results of the investigation indicate that cooperation with the Police of the Czech Republic and early detection of the dangerous situation of the Medical Operations Centre tend to be crucial. All 10 respondents have experienced verbal aggression, half of them have experienced physical aggression. A few respondents expressed interest in self-defense courses, and those who keep fit by moving are interested in contributing to sports activities. This work can be used as an educational material for health care professionals or as a source of information in the area of self-defense and security in the South Bohemia Region.

Vítek, Pavel ; Friml, Dominik (referee) ; Veselý, Libor (advisor)
This thesis deals with strategies used in pick-and-place applications. In the theoretical part, the main parameters of the robot-conveyor system, such as efficiency and gripping rate, are first described. Subsequently, pick-and-place problems are divided into solutions with one or more robots. Then, the paper focuses on well-known strategies such as FIFO or SPT. The construction of a cost function based on the position of an object on the conveyor is described. Furthermore, the creation of the simulation is described, which is then compared to the B&R solution. Then, the different strategies in different scenarios are analysed. Finally, the rules for the selection of strategies are formulated and the whole paper is summarized.
