The content of this diploma thesis is the design of adjustable armchair, which will keep the rules of sitting ergonomics, which will be influenced by the specified requirements for resting seating and will be in accordance with the standards dealing with the given issue. The starting point for designing is the theoretical part, which describes seating issues, deals with the importance of seating in the context of time, emphasizes the importance of seating furniture ergonomics and at the same time points out the benefits of relaxation on adjustable resting furniture. The thesis focuses more on the positioning function. There is a research of historical adjustable armchairs in this thesis. Also there is a research of the current offer and the positioning mechanisms which are used nowadays. The basis for the practical part is the list of suitable technological processes and materials used in upholstery production which the author considers for realization of the final armchair design. The practical part is divided according to the individual design points. There is the stage of sketching and the stage of verifying the way of positioning using both 3D and physical models. For a better orientation and understanding of author‘s working procedure, the practical part is extensively accompanied by visualizations and photos. The final design is demonstrated by the 3D model, its visualizations and the drawing documentation that will serve to produce a functional prototype.

This thesis focuses mainly on threats to the safety of nursing personnel. These include a high risk of injury when positioning and the risk of developing musculoskeletal disorders,which can lead to a long-term sickness of the member of the medical staff. The theoretical part is divided into four parts. The first part describes in particular the need for safety and security, as well as factors that have an influence on this human need.Attention is focused also on ensuring safety while providing nursing care, especially when positioning patients. In connection with safety during this activity, a section in this thesis is devoted to the kinaesthetic mobilization, which offers a slightly different view of the positioning and patient handling. In the last chapter of the theoretical part, findings concerning the prevention of damage to health nurses in providing nursing care are summarized. The thesis has three objectives that were formulated as follows. Objective 1: Determine whether nurses use kinaesthetic principles during a patient handling. Objective 2: Determine whether nurses, in their opinion, have enough equipment to ensure safety during patient handling and positioning. Objective 3: Map the causes of the use of inconsiderate patient positioning techniques. Based on these objectives, the research question and three hypotheses were set. Research question: What are the possibilities for improving patient handling and positioning within the nursing process? Hypothesis 1: The use of kinaesthetic depends on the type of department. Hypothesis 2: Nurses use bad positioning techniques despite their knowledge that they can harm their health and also patient's. Hypothesis 3: Lack of time is the most common cause of the use of the inconsiderate method of positioning. In order to fulfil the objectives, a quantitative research, for which we choose the questionnaire method of data collection, was conducted. The questionnaires were designed for nurses working in the department of surgery, internal medicine and the department of aftercare. The survey was carried out in 7 hospitals of South Bohemia. In total, 340 questionnaires were distributed into these hospitals.The final research sample, therefore, consisted of 209 completed questionnaires. The rate of return was 61%. The obtained data were processed and analysed using Microsoft Excel 2013, then analysed statistically using the chi-square test. The results were processed into graphs. Based on the results, we can conclude that the hypothesis 1 is confirmed. We found that kinaesthetic is used most in aftercare departments. On the contrary, surgery departments use it the least. This is probably due to a different composition of patients on these wards.Hypothesis 2 was, for testing purposes, divided into two working hypotheses. H2a: 60 % nurses know that classical principles of positioning can damage their health. This hypothesis has been disproved. A corollary is HA: Knowledge of nurses about the risk of an injury is not 60%. The research has also revealed that almost three quarters (74 %) of the nurses know that positioning can damage their health. The second part of the hypothesis 2, i.e. H2b: 60 % nurses know that the classical principles of positioning can damage the health of the patient, has also been refuted, and thus applies HA: Knowledge of nurses about the risk of an injury to the patient is not 60%. The results of the survey showed that only 24 % nurses consider the classic method of positioning a risk to patient's health. Hypothesis 3 was, through our research survey, refuted. Sisters see the most frequent reason for using the inconsiderate positioning procedure in the lack of staff.We managed to answer the research question by analysing literature in the theoretical part and performing the survey in the practical part of this thesis.An output of this thesis will be an expert article published in a professional journal and a presentation at a professional conference

In the Laboratory of the Experimental Biophotonics at Brno University of Technology, a new generation of the Coherence-Controlled Holographic Microscope (CCHM) is being developed. Because of the automation of certain microscope procedures, a fully motorized three axis computer controlled manipulator of the sample is to be employed. A fast and accurate lateral positioning in a range of several centimeters is required. For the focusing capability, very precise positioning in the optical axes is required as well. Initially, the basics of microscope manipulator design are presented. Then, commercially available solutions are introduced and compared with special focus on its possible implementation in the new generation of CCHM. However, due to the specific design of the new CCHM, available manipulators are not suitable. Therefore, a new optimized manipulator design is introduced in the second part of the thesis. A selection of its appropriate elements, especially actuators, is based on a review. For the new manipulator design, a technical documentation was made and a testing software was developed. A crucial part of the manipulator was assembled and tested.

The main research topic of this dissertation thesis deals with the influence of the working accuracy related to large CNC machines on the required workpiece properties. The state-of-the art has constantly been developed and the customer’s requirements directed to manufacturers of the machine tools are increasingly demanding. There is required a high accuracy, reliability, shortening delivery times etc. The manufacturer is expected to fulfill all the customer’s requirements. The machining accuracy is dependent, among others, on the positioning accuracy of a machine tool that represents the position of the cutting tool relative to a workpiece. The accuracy of a particular machine tool is therefore a limiting factor concerned with reaching the highest accuracy and quality of a workpiece. Acceptance test procedures are initially realized within a manufacturing shop floor and then within a customer environment. The main subject of the testing procedures is to verify. basic properties of a machine tool such as basic dimensions of a machine, strokes in all respective coordinates, machine travels and spindle speeds. A machining of a workpiece with a desired precision specified by the customer is also performed. In this thesis, a new methodology to calculate and determine errors concerned with machining on vertical lathes is proposed with the aim of predicting the machining accuracy of CNC machine tools. The objective of this work was to determine the influence of machining accuracy of a CNC machine in connection with a subsequent geometrical accuracy of a workpiece. Considered position of a tool relative to a workpiece will be affected by errors concerned with a kinematical inaccuracy, geometrical errors and errors related to machining forces. A vertical lathe SKIQ 30 produced by TOSHULIN, a.s. has been used as a testing machine on which the proposed methodology has been verified. During processing various calculations in this thesis there has been found out that the machining inaccuracy of the machine – main topic of interest – is influenced by the machining conditions such as cutting conditions, material to be machined and even the setting of working positions of the machine. For instance, a position of the cross slide is determined by a workpiece height and a position of the lathe carriage that is determined by a workpiece diameter and a travel of the slide that is also determined by a workpiece height. It can be stated then that to predict the machining accuracy of work pieces, it is important to know the behavior of the machine in its all range of working envelope. Based on the information acquired about the behavior of the machine, it can be determined an appropriate position for a workpiece setting that allows utilizing the maximum reachable accuracy with respect to the stiffness and geometrical accuracy of the machine tool. An appropriate setting of initial working position may influence the subsequent geometrical accuracy of a workpiece.

OF MASTER THESIS Tittle of master thesis: Use of individual types of positioning on patients after stroke in the acute and subacute phase of rehabilitation from the perspective of occupational therapy. Stroke is one of the diseases that most affects the human population. It can result in temporary disability, permanent consequences and death. The patient's positioning after a stroke can affect many risks of secondary changes. The aim of this work is to find out how occupational therapists are involved in the positioning of patients in the acute and subacute phase after a stroke in stroke centers in the Czech Republic and how the positioning in stroke centers takes place. The literature and recommended procedures show that the correct positioning after a stroke in the acute and subacute phase prevents the development of immobilization syndrome and secondary changes. Positioning patients after a stroke can affect muscle tone, shoulder pain, prevent subluxation in the joints, maintain passive and active range in the joints, etc. In patients after a stroke, agitation should occur from the affected side to support the return of sensorimotor functions and to involve the affected parties to activities. The occupational therapist is most involved in positioning the affected upper limb, especially to...

The main subject of this doctoral thesis is the influence of the geometrical accuracy of large CNC machine tools on desired features of produced work pieces. Doe to globalized market environment and competition producers of machine tools have changed their strategy for delivery of their products to customers. The main issue is not only to deliver a machine tool as such; supporting instructions related to the technology of the cutting process on the machine tool are of great importance. When taking delivery, the customer can see a new machine tool that will produce by him specified work piece with a desired accuracy. In the proposed thesis, a development of a novel methodology of measuring vertical lathes for prediction of chosen geometrical parameters of work pieces is introduced. The main goal of this work has been to determine the influence of the geometrical accuracy of selected design groups of a vertical lath on the future geometric accuracy of the work piece. The proposed methodology has been developed and verified on a selected vertical lath SKIQ30 produced by TOSHULIN, a.s. For identification of chosen parameters of the vertical lath a measuring system using latest measuring technologies has been applied. The basic tool for measured data processing has been a set of statistic methods for prediction of behaviour of measured design groups of the machine. The foundation for statistical processing has been calculation of geometrical deviations obtained from algorithms designed for proposed measurement methodology. The proposed measurement methodology for vertical lathes has been divided into two parts. In the first part, the methodology of measurement and evaluation of linear axes is solved, where a measuring system Laser Track has been used. The employment of the system Laser Track turned out to be very suitable. Conclusions related to the accuracy of the measuring device have been drawn in the thesis. The second part of the proposed methodology is represented by observation and description of the rotating disk, where non-contact position transducers have been used. In the course of the doctoral dissertation it has been observed that the studied (with respect to the geometry) behaviour of the machine is significantly affected by the cutting conditions. To these belong the loading of the rotating disc by the mass of the work piece, angular velocity of the rotating disc and the operating time of the machine. Based on these observations it can be stated that for prediction of work piece features it is essential to know the behaviour of the machine tool in the whole range of the operating speeds and loading of the rotating disc. A part of the proposed methodology for measuring vertical lathes seems to be very suitable for a design of a diagnostic system that could be applied on large rotating disc. Furthermore, it is recommended to extend the doctoral thesis in order to develop a unit for compensation of geometrical errors on rotating discs of vertical lathes.
