Importance of quality indicators in the healthcare – in case of musculoskeletal rehabilitation –
1-11Views:166Nowadays the term of management is so popular. It has an essential role in the professional life, moreover in the every day life too. Creating and using the quality indicators (one of the qualiy management tools) contribute to the improvement of the operation of the healthcare system and to the development of the quality of healthcare services. The aim of the paper is to define service quality and its dimensions in healthcare and to highlight the role of quality indicators. The research calls attention to the absence of indicators measuring the different aspects of quality directly, the difficulties of measuring service quality and the need of establishment of more specific measures in healthcare. A special area of healthcare, there habilitation of musculo skeletal diseases will be discussed. As a research my approach is to define all the indicators that are already used in this area of the healthcare. This examination is extremely important because one of the most commonailments are the musculo skeletal diseases and their number is just increasing.The paper is mostly descriptiv and follows analitical methods based on the international and Hungarian professional studies, informations. To access databases I was helped by the OSAP (National Statistical Data CollectionProgramme). Besides the importance of quality indicators the research calls for the need for more specific measures.

Possibilities of Improving Salt-Related Water Quality on a Hungarian River
13-22Views:166The purpose of the study was the assessment of the salt related quality of river Kösely and its tributaries and to determine with calculations whether it is feasible to achieve improvement of the demonstrated water quality by the means of dilution in the frame of a PhD study. Besides data collection a series of twenty-eight Electrical Conductivity (EC) measurement was carried out at eleven sites along the river system. The resulting EC values all year long on every reach of the river exceeded even the tolerable values specified as irrigation water quality criteria and water quality standards in the Water Framework Directive. In the paper, we introduce the results of the survey along with authority surveillance data series from earlier years. Investigations in the water using anthropogenic activities causing this special water quality problem were also carried out and the results – quantitative and qualitative aspects as well – are introduced here. Since the pollutant is a conservative material, the calculations were performed using the simple dilution equation which is based on the law of conservation of mass. The findings of the calculations were the identification of those reaches of the river system where adequate water quality can be achieved by dilution considering the limiting factor of water delivery capacity. Our conclusion is that under current conditions of water management and water using activities there is no way to meet quality requirements with dilution. This can be achieved only by prevention or reduction of salt load.

Optimizing the combustion processes of a small scale solid fuel-fired boiler
358-369Views:146Over the last decade, the public has been paying increasing attention to reducing greenhouse gas and acid rain emissions and reducing particulate matter, which is extremely harmful to health and the environment. To improve air quality, the European Commission has achieved a range of measures to reduce air pollutant emissions in the transport, heat and electricity, industrial and agricultural sectors. In Hungary, the amount of gas and solid air pollutants from solid fuel combustion used by the public during the heating season represents a significant percentage of the total amount present in the atmosphere. In 2016, taking into the total emission, the 29% of CO2 emissions; 85% of CO emissions; 75% of the particulate matter emissions and 21% of the NOx emissions were derived from households. It follows that the improvement of air quality can also be achieved by controlling the emissions of solid fuel combustion plants. During our research we aimed to optimize the operation of a newly purchased TOTYA S18 boiler and a pilot pellet boiler. Operating the boilers in the correct mode minimizes air pollutant emissions, and the greater part of the heat generated is actually turns to heating the home, as with poor settings, a lot of heat leaves through the chimney. The data obtained during the tests can also be used to determine whether the boilers comply with the emission values set out in Commission Regulation (EU) 2015/1185.

Surface Quality of Carbide Metal After Electrical Discharge Machining
31-38Views:146Recently, the requirements for machining shape-complex products made of hard-to-machine materials, including carbide, have been increasing significantly. However, their machining is rather problematic. Additionally, a high-quality standard of the machined surface is generally required, not only in terms of roughness but also in terms of the geometric accuracy of the machined surface. All this while maintaining a high level of economy in the machining process. However, meeting these demanding requirements in real technical practice is not always an easy task. Moreover, in combination with modern machining processes, only a limited number of production technologies can meet this requirement. Therefore, due to the high demands placed on today's modern production and the required high standard of the machined surface, progressive EDM technology is increasingly finding its application. And it is through this progressive technology that it is possible to achieve relatively good success in carbide machining. The aim of this paper was therefore to describe in detail the results of an experimental investigation aimed at identifying the quality of the machined surface achieved in terms of the roughness parameters of the machined surface in the electrical discharge machining of selected types of carbides using a wire tool electrode.

Utilisation and Quality Management of Power Plant Fly Ash
329-337Views:224Over the past decades, both the residential and industrial energy demand has increased due to the continuously growing consumption and production. As a large share of the electricity is still produced using fossil fuels, the utilisation of the by-products is a contemporary and pervasive issue. Fly ash is generated in large quantities in coal-fired power plants and has been proven to be an appropriate raw material for various industrial uses. Among others, it is applicable as an additive and lightweight aggregate in the cement and concrete industry, can be used for CO2 sequestration, glass foam production, catalyst production, or as a base material for geopolymers, as well. Geopolymers are inorganic polymers produced via the reaction between solid alumina and silica containing or alkali silicate materials in alkali media. Due to their numerous advantageous properties and wide variety of utilisation possibilities, research on fly ash base geopolymers became widespread topic. The quality of fly ash is determined by technical requirements, and the degree of quality control requirements depends on the final use. In certain fields of applications, standards and regulations have already been created to ensure the consistent quality of the final products made from fly ash, e.g. in the cement and concrete industry. There are various methods for fly ash processing, however, the methods to achieve the necessary properties are not standardised.

Production of Liquid Hydrocarbons from Plastic Wastes
345-350Views:148Thermal pyrolysis of HDPE, LDPE, PP and PS plastic wastes were performed in a batch reactor and the yields of pyrolysis oils and liquid transportation fuels prepared by atmospheric distillation were determined. The gasoline fractions were tested in a traditional spark-ignition engine without any modifications or fuel blending. Fuel consumption and exhaust gas emission (NOx, CO) were measured and compared to a commercial fuel (RON = 95). PS generated 70.5% gasoline range hydrocarbons from the solid waste, followed by PP with 42.1%, LDPE with 40.8% and HDPE with 37.3%. The fuel consumption was reduced by 9.1-9.4% in the case of PS compared to reference measurement. Reduction in fuel consumption was noticeable at HDPE, LDPE and PP as well. PS gasoline decreased by 91-96%, while HDPE, LDPE and PP more likely increased the CO emission of the engine compared to commercial gasoline. The results show that pyrolysis of plastic wastes is a promising method to generate value added liquid transportation fuels and reduce the footprint of waste accumulation in landfills.

Discussion on São Paulo Mobility Plans
17-33Views:161Since urbanization rising and urban demographic increase, urban transportation has been an important life quality aspect and a strategic decision for cities. Mobility seems to follow citizens' behavior and be influenced by urban cultural changes at the same pace it influences back the city routine and resident’s conduct. The discussion around the future of mobility gained new magnitude nowadays since some sort of vehicles have proved themselves as the cause of significant environmental impact, while others showed themselves as alternatives of low impact for different reasons – from quality public transportation to individual transport with minimized emissions. The city of São Paulo in Brazil published its Master Plan in 2014 and its Mobility Plan in 2015, analyzing the current situation and proposing a future for the city’s transportation system. This paper intends to analyze both plans, construe the popular participation in their formulation and application, discuss how data and strategy were presented and whether they are aligned with other countries’ thinking on the subject. As a city of over 10 million inhabitants, in a Metropolitan Region of 39 cities with over 20 million inhabitants, the transportation system of São Paulo is not an easy or single-solution issue. It is known the need for a combination of different transportation modes, requiring likewise new visions for all methods. Owing to the fact that modes complete each other and, in that manner, may reach a wider range of options for the population to plan daily life, then a system with a great variety of modes ensures the best functioning of them all. This paper focuses on an outsider view that searches for answers and solutions on the São Paulo transportation system, having as a base what is considered outstanding in the world for this issue.

Evaluation Opportunities tor Recreational Sport Services – Adapted to Higher Education Environment
150-164Views:237In our study, we analyse various researches dealing with quality aspects of sport services, and different quality models related to the interpretation of quality. The results which were obtained in the framework of primary research activity present the opinions of students from five different research universities. Sport services’ operation and sustainability are determined by market regulations, as parts of the service industry. Considering that the university leisure sports services take place in a competitive environment, the universities often have to compete with external sports service providers for achieving confidence of the young generations. For the qualitative tests, we used the QSport-14 measurement scale, which is generally applied by sports centres. This scale investigates the sports services according to three different aspects: (1) instructors, (2) infrastructural facilities and equipment and (3) offered sport programs. We have adapted the measurement scale to the university environment because of the differences and special characteristics of external sports service providers and university sports services. In addition, we analysed the factors influencing recreational sports, and we also examined that what changes would be needed in order to improve the quality of recreational sport activities in higher education.

Estimation of the Potential Runoff Quality Improvement as a Result of Applied Green Infrastructure Measures in a Hungarian Town
34-41Views:222Green infrastructure measures improves the quality of surface and subsurface waters along with increasing the water balance on the town level. The aim of the study is to estimate the potential runoff quality improvement by applying stormwater BMP-s along traffic roads in the town. This is of high priority in the aquifer protection area where runoff water may infiltrate into the aquifer carrying pollutants from the surface. Estimations are applied: first we determine the surface of traffic roads, then estimate the quantity of different kinds of pollutants accumulated on the surface and thirdly we estimate the expected performance of the applied green infrastructure elements based on findings in the literature. We determine the impervious urban surface area associated with transport-related functions within the protected drinking water recharge area using GIS technic using orthophotos. We estimate the expected reduction of runoff pollution assuming that stormwater BMP-s are applied in the area. The overall goal is to make the significance of diffuse pollution more obvious and enhance drinking water protection through taking diffuse pollution into consideration.

Analysis of the Causes and Effects of Noise from Rail Transport
116-130Views:124Noise emissions from rail transport are a major concern, as they affect both the environment and people's health and quality of life. Among the many sources of noise emissions, rail vehicles and infrastructure are a major factor. With regard to rail noise emissions, it can be concluded that noise effects are influenced by a number of factors. These factors include train speed, track condition, traction technology and the noise abatement methods used. The negative effects of noise exposure include sleep disturbance, stress and mental health deterioration. It also affects the quality of life of people in urban areas and property prices. It should be emphasised that reducing noise emissions from rail transport is key to creating a healthier and more sustainable urban environment. To achieve this, it is important to use modern noise abatement technologies, improve infrastructure and implement noise abatement actions effectively. Transport authorities and railway companies should work together to achieve a more noise-free rail transport, to improve people's quality of life and to protect the environment.

The Individual, Education or Work Environment Influences the Quality of Graduates’ Employment?
244-260Views:201In this paper I examine what has an effect on the quality of the graduated students’ employment. The quality is measured by the the discrepancy between the educational attainment of workers and the educational requirements of their job. On the base of this I can distinguish matching and overeducated workers. The latter category can be divided into two other groups, so called genuinely overeducated, who are not satisfied with their mismatch, and apparently overeducated, who are satisfied with their mismatch. Using multinomial logit model I try to identify those individual, educational and workplace’s characteristics that influence being matching, apparently, or genuinely overeducated using the database of students graduated in 2007 and 2009 in the University of Debrecen. I try to test those factors that were determined in the literature like mobility and commuting propensity, market rigidity, career mobility, job tenure.

What is worth knowing about the establishment from a work safety point of view
24-31Views:127Under establishment, we mean the process that results in the creation of a new unit (eg factory, plant, office, etc.), a workplace or an existing one what will be renewed, expanded or restructured, or installed; installed on a machine, plant, appliance, whether or not for productive or non-productive purposes. It is generally true that the design, construction, use and subsequent operation of workplaces, facilities, technology, materials, energy, personal protective equipment; production, distribution, import, transportation, movement, use and use of workplaces; in the absence of these, the requirements of the scientific-technical standard can be expected. An employer, operator, and service provider must adapt to market conditions. Accordingly, it should monitor the expectations of customers, business partners, market changes, trends to adapt to expectations, and therefore constantly develop their products, services, produce reliable quality, ensure that quality meets the market expectations providing personal and material conditions to ensure that employees can effectively and safely meet market expectations. The recognized business perception of the employer is to accomplish the above, the objectives to be achieved must be formulated, priority should be given to the potential risks (with particular regard to occupational safety risks) to be measured, measures to be taken to ensure effectiveness, short-, medium- and long-term planning, investment.
