The aim of this thesis is to compare various options, how can companies meet the mandatory proportion of employment of handicapped people and also analyze tax impacts on companies considering the particular option they have chosen. The thesis is divided into five chapters, first of them is about free labor market and describes various options, how can companies meet the mandatory proportion of employment of handicapped people. Then the second chapter contains information about employers of handicapped people in protected labor market. The next chapter refers to so called protected working place, which is directly related to the possibility to receive purposeful contribution from the state. The last chapter of the theoretic part of the thesis is about tax relief for companies that employ handicapped people. Subject of the practical part of the thesis is to analyze accounting and tax data of real company and try to modify them based on hypothetical situation what will be changed in case of employment of handicapped person in this company. There are mainly tax impacts on the company analyzed.

This thesis deals with space conditions and working place in a computer lab. It also de-scribes the rules of correct seating of students and their feeling of comfort related to the stay in a computer lab. Theoretical part contents information about ergonomic requirements on the arrangement of working place at the computer. The information concerns table, chair, monitor, key-board and mouse. The requirements on space conditions of a computer lab are intro-duced as well as other factors. For example floor area, height of a room, position of working place and factors such as lighting, windows, noise, microclimatic conditions and ventilation. Working with computer effects our health, for example musculoskeletal problems, visual difficulties and psychical troubles are mentioned. Also the musculoskeletal system, sitting position, posture and examples of compen-sation exercise (concerning static load) are described in this thesis. The final section of the theoretical part is focused on the school stress, its conse-quences and also the school which supports health. The aim of the thesis is to map space conditions and working place in a computer lab in Písek district and to find out students opinions on feeling of comfort while staying in a computer lab and respecting the rules of correct seating. The second part of thesis gathers the results of my research. It concerned students from 6th till 9th classat chosen primary schools in Písek district by the method of ob-serving and the results were compared with the established criteria. Also the anonymous questionnaires were used. The space conditions of computer labs, working places of students and respecting the rules of correct seating were evaluated by observing. The questionnaires were focused on the recognition of students feeling of comfort while staying in a computer lab. Established facts were statistically tested by using chi-square test. The final results of the research show that working places in computer labs at pri-mary schools are suitable for ergonomic requirements. While observing of respecting the rules of correct seating, it was acknowledged, that these rules are not followed, despite the students have adequate conditions for their work. Although in the observed computer labs there were some deficiencies concerning space conditions and other factors, the students feel comfortable while staying in a computer lab. Because static load influences the musculoskeletal system of the students itis neces-sary to apply the factors of precaution at schools, especially as for the rules of correct seating. The students should be familiar with these rules and following the rules should be regularly and consistently controlled by teachers. The deficiencies in computer labs and on the working places are necessary to re-move to create adequate surrounding and conditions for the work of students. Appropri-ately arranged working place is basic requirement for the precaution of musculoskeletal problems and it also enables easier way of how to follow the rules of correct seating. Long-lasting sitting and unsuitable working conditions influence negatively the health of the students and that is significant also for the future. Health problems can be present till adulthood. The students should be aware of the risks and they should be taught to arrange their working place properly before they start working there.

Employers’ responsibility of the health and safety on the environment for the employee who is teleworking is one of the questions in this essay. What is teleworking, in relation to the aim for this essay, is the second question. Teleworking is an employment which is growing and the Swedish legislation is vague. The methods which have been used to investigate and understand the legislation is jurisprudence method and the legal dogmatic method. After the investigation of the aim and question of this essay it is possible to say, the Employers always have the responsibility for the environment of employees’ health and safety. But teleworking makes it hard for the employer to verify the health and safety on the environment, when they do not know where the employer is working.

Introduction: Work-related stress is one of the most challenging issues on workplaces. Reduced ability to relax and recover has been proposed as a key factor behind the increase of stress-related illness among workers. Massage and mental training are two commonly used techniques which may have positive effects on the ability to recover. One technique to help workers recover is a “recovery chair” which include both mechanical massage and mental training programs. However, it has not been scientifically evaluated yet whether using the techniques included in the “recovery chair”, both separately and in combination, as a health promotion tool. Aim: The overall aim of this thesis was to explore the psychological and physiological effects of the mechanical massage and mental training programs included in the “recovery chair”, both separately and in combination, as a health promotion tool for Swedish workers. Methods: In this study workers were randomly assigned to one of the following groups: i) Mechanical massage combined with mental training (n=19), ii) Mechanical massage (n=19), iii) Mental training (n=19), iv), Pause (15 min break in the armchair, n=19), v) and a Control group (n=17). Psychological effects were measured by the ”Swedish Scale of Personality” (SSP) and physiological effects were measured by heart rate, blood pressure and fingertip temperature, immediately before the randomization, after four weeks and after eight weeks (end-of-study). Results: Psychological effects: The results showed that receiving mechanical massage was associated with a significant decrease in “Somatic Trait Anxiety”. The participants in the mental training group showed a tendency to decrease in “Somatic Trait Anxiety”. The participants who received both mechanical massage and mental training showed a significant decrease in “Stress Susceptibility” between four and eight weeks. The results also showed a significant decrease in “Somatic Trait Anxiety” and a significant increase in “Detachment” for the paus group. Physiological effects: As compared to pre-intervention assessments, participants in the massage group condition showed significantly reductions in their resting heart rate, systolic and diastolic blood pressure and an increase in their fingertip temperature directly after the intervention (post-intervention). The mechanical massage and mental training group showed a significant increase in diastolic blood pressure during the last four weeks of the study. The participants in the mental training group showed a significant decrease in their heart rate, when compared the start of the study to week four. The pause group tended to have lower systolic blood pressure at post-intervention assessment when compared to the pre-intervention assessment. The participants in the control group showed significantly decrease in heart rate and their systolic blood pressure. Conclusion: The workers’ who used the “recovery chair” with mechanical massage or mental training programs, either separately or in combination, for eight weeks during working hours reported a positive impact on their levels of anxiety and stress sensitivity. The results also showed positive effects on the workers' blood pressure, pulse and fingertip temperature. The effect was particularly strong for workers' who received only mechanical massage. This indicate that stress management interventions as work place health promotion activities clearly have a potential to provide significant benefit for health and wellbeing for workers.

The aim of my diploma thesis is to produce an automated workplace for an antenna radiation pattern measurement with the R&S ESCS 30 measurement device. The result is a program named SFMAP.EXE. The measurement process is controlled by this program according to user defined parameters. The program collects the R&S ESCS 30 measured values and can evaluate the radiation angle values of the antenna. It can set up some parameters of the measurement device and controls the rotation of the turn-table, where the measured antenna is positioned. The controlling device based on FT232BL circuit was developed to capacitate the program to control the turn-table. With created program the turn-table can be controlled over the USB interface. This solution allows using any PC or notebook because of its standard equipment - the USB interface.

This Master’s Thesis is dealing with measuring antennas in far field. Especially with automation this measure, direction sensors made by optical mouse, Integrated Hall ICs for Linear and Off-Axis Rotary Motion Detection and remote unit this workplace, which can made communication with PC by USB. It describes the making control program for the PC.
