Design of a mattrack unit of an RC model produced by the 3D printing
Mašek, Dominik ; Rekem, Jakub (referee) ; Otipka, Václav (advisor)
The focus of this bachelor thesis is 3D print and design of mattrack unit for the RC off-road car. In the first part there are description of 3D print technologies, materials for 3D print and evaluation which of this method is suitable for hobby printers. The second part is focused on technical solution and the design of mattrack unit, most of unit parts are made by 3D print. First step was choosing of type of construction which should be inspiration for this mattrack unit. It was necessary to choose suitable tolerance of holes and pins to get required deposition of printed parts. There was problem with an unstrung belt when bodies of guiding wheels rotated. This problem was solved by the mechanical limitation of rotate. The construction is described by the technical documentation which was created by the 3D model.

Automatic exchange of workpieces in CNC horizontal milling centers
Mašek, Dominik ; Marek, Tomáš (referee) ; Marek, Jiří (advisor)
The thesis focuses on the issue of automatic workpiece change in CNC horizontal milling centres. On the basis of a system analysis of the problem and the current state of the market, a suitable method of automatic workpiece change for a large machine tool, which can be specified as a machine designed for workpieces weighing more than 10 000 kg, is to be proposed. In the first part of the thesis the problem of automatic workpiece change is discussed, followed by a market analysis. The design of the structural solution consists of the design and evaluation of solution variants, the necessary technical calculations of the selected variant, a 3D model and selected drawings. The machine is rated for a load of 40,000 N from the pallet and workpiece.

Methodology of gait school of a patient with transfemoral amputation
Mašek, Dominik ; Černý, Pavel (advisor) ; Půlpán, Rudolf (referee)
Title: Metofology of gait school of a patient with transfemoral amputation Objectives: The main objective of this thesis is to give a comprehensive overview of methodology of the gait school from the prosthetic and rehabilitation care perspective of patient with transfemoral amputation. Methods: A qualitative research was used together with method of data collection, informal interview with an expert and observation of therapy. Results: The methodology of gait school is necessary for proper use and wearing prosthetic device. It positively influences the life of a patient with a transfemoral amputation. in conclusion of this thesis is proven the crucial importance of early starting with the methodology of gait school as soon as possible is important for quickly return to normal life. Keywords: amputation, rehabilition, gait, prothetics

Postural physiotherapy concentrated at axial stabilization of actively sporting children on a competitive level
MAŠEK, Dominik
This work is focused on the topic of stability of the axial system at actively sporting children on the competition level. In the theoretical part I write about basic knowledge about the postural system and deep stabilization system. The practical part of my thesis is processed as a qualitative research comprising input and output kinesiology analysis and input and output posturographic examination. The research took place at the Uran office at the University of South Bohemia, České Budějovice. The research sample was consisted of five actively sporting pediatric patients (two boys and three girls) aged 6 to 11 years. Three patients (two girls and a boy) do gymnastics and two patients (a girl and a boy) do the Korean martial art called Taekwondo. Therapy contained eight treatments lasting 15-20 minutes. Rehabilitation therapy included posturograph with NeuroCom Balance Manager system. Another three exercises were practiced individually at home. The aim of this work was to improve the axial stabilization using therapeutic programs and additional exercises and then subsequent evaluation of the results of these eight treatments. Here I follow the idea, that even short exercising of deep stabilizing deep system during training can lead to an overall improvement in the stabilization of the body, reducing the level of hazing superficial muscles and preventing the occurrence of clinical symptoms and complications, that are common in modern society, such as back pain, prolapsed intervertebral discs, etc. Results obtained by therapy proved that patients' axial stability and overall posture im-proved after eight therapies. This thesis may serve as a resource not only for health care workers, but also for the general public and sports coaches.
