Presented paper concentrate on problems connected with FMEA method usage in industrial enterprise. There is in the paper a description of the basic rules of FMEA method and competition between FMEA analysis and gap analysis. The analysis of defects has been done to find recommendations how to eliminate or restrain them. On the basis of conducted research we found that selection of staff to the team is very important factor in the FMEA analysis undertaking process. The staff should have appropriate level of knowledge about FMEA method methodology and other tools which are indispensable in the process of implementing this method within the company.
The following paper concentrates on some problems resulting from the use of Quality Function Deployment method in industrial enterprises. It is not an easy task although the method itself has many advantages. The aim of the paper is to analyse basic international literature as well as the main advantages and limitations of the Quality Function Deployment

Rapid development of road construction imposes requests on fast and quality methods for earthwork quality evaluation. Dynamic methods are now adopted in numerous civil engineering sections. Especially evaluation of the earthwork quality can be sped up using dynamic equipment. This paper presents the results of the parallel measurements of chosen devices for determining the level of compaction of soils. Measurements were used to develop the correlations between values obtained from various apparatuses. Correlations show that examined apparatuses are suitable for examination of compaction level of fine-grained soils with consideration of boundary conditions of used equipment. Presented methods are quick and results can be obtained immediately after measurement, and they are thus suitable in cases when construction works have to be performed in a short period of time.

The theoretical framework for this research is the sociology of leisure and the sociology of health. Because sedentary behaviour (of employees) is a relevant new research area with important health risks, we decided to focus our attention on this subject. Moreover, sedentary behaviour in the workplace seems to be an important topic for the future.
The general aim of the research is to provide a platform for exchange on effective approaches for promoting health-enhancing physical activity among workers, to learn from experiences in different European countries and to promote the most effective approaches across Europe.
Two methods of qualitative research were used. The first was the method of expert judges. By way of direct interview, the statements of nine persons were collected, all of whom were recognised as competent judges. The second method was the analysis of the content of the literature (quality method). Using the computer program Atlas.ti, the respondents and their answers were examined.
Most of the indications (89%) concerned responses indicating physical activity. In general, the experts are quite physically active and keep a healthy (in their opinion) diet. They have both knowledge and appropriate skills in physical education. They point to the growing interest of younger academics in health and fitness, which may be associated with trends in popular culture, such as a sporty lifestyle, the cult of the body, various healthy diets and supplements, etc., that are becoming the universal fashion.

Comparison of retrospectively ECG-gated coronary computed tomography with and without adaptive tube voltage, tube current parameters and individualized contrast media injection protocol to reduce ionizing radiation dose
Objective: The aim of the study was to estimate the decrease in ionizing radiation exposure dose using adaptive tube voltage, tube current parameters and individualized contrast media injection protocol compared to basic retrospectively ECG-gated CCTA protocol and to compare image quality.
Methods: This retrospective study consisted of 30 consecutive patients who had body mass index (BMI) between 25 kg/m2 and 30 kg/m2 and underwent retrospectively ECG-gated CCTA. We have enrolled 15 patients which were scanned with an adaptive tube voltage, tube current and an individualized contrast media injection protocol (study group), the other 15 patients underwent basic retrospectively ECG-gated CCTA protocol (control group). Comparison of ionizing radiation effective dose, subjective and objective image quality was accomplished. Differences in ionizing radiation effective dose were deemed statistically significant if p < 0.01, for other variables we considered a p value of less than 0.05 to be statistically significant.
Results: he difference of a mean effective dose between study and control groups was statistically significant (6.39 ± 0.88 mSv and 17.44 ± 2.45 mSv, p < 0.01). Despite significantly higher image noise, significantly lower contrast-to-noise ratio and signal-to-noise ratio in a study group, both groups showed comparable average image quality (62.03±16.85 and 39.98±8.79, p < 0.01; 5.16±2.03 and 7.71±1.28, p < 0.01; 3 (2.5-3) and 2.75 (2.75-3), p = 0.95).
Conclusions: Despite higher image noise compared to basic retrospectively ECG-gated CCTA protocol, adaptive tube voltage, tube current parameters and individualized contrast media injection protocol allows substantial reduction in ionizing radiation exposure dose to a patient (up to 63%) with an adequate image quality for the evaluation of coronary arteries.
Development of the walking ability and self-care of patients with Down syndrome is affected by their body weight determining their lifestyle to a great extent. Objectives: The study aimed at the determination of body mass index for persons living in residential institutions and families, exploration its impact on walking and self-care as two, objective factors of life quality. Method: Data collection of persons aged 3-35 with Down syndrome living in families covered seven counties, while those of living in residential institutions covered thirteen counties in Hungary. In the 183 cases studied 76 people in residential institutions, 107 people lived in families. The cross-sectional study was processed by non-random sample selection. The questionnaires were filled out by health visitors and care takers edited by their own. Results: 50.6% of adults and 26.1% of children belonged to the overweight or obese category. Their residence showed a significant correlation with the body mass index (p< 0.001). Overweight and obese persons in families, while thin ones were more prevalent in institutions. Regarding the walking ability and self-care of the persons living in families a significantly higher level of development was achieved (p< 0.001). Walking ability (p = 0.001) and self-care (p = 0,008) were worsened by less body weight significantly, while overweight or obesity influenced it less negatively. Discussion: The claim is not further acceptable whereas persons with Down syndrome are more prone to obesity than average people. However unfavourable weight gain in adults draws attention to the necessity to a healthy diet and regular exercise. The people living in residential institutions with significantly lower body mass index and the associated low development of walking ability and self-care envisages an urgent reform of residential institutions. Life in the institutions negatively affects the walking ability and self-care, and thus significantly reduces the quality of life of persons with Down's syndrome.
