    Nowadays, we can observe an increasing trend in the spread of non-communicable diseases. It is important to highlight the social factors that negatively affect health. Determinants includes income, education and the research-relevant working and living conditions. From a labor market perspective, unemployment and poor working conditions are a significant responsibility for the deterioration of mental and physical health. Health is also affected by employment conditions. Extended working hours have been shown to be harmful to health. Poor health has generates poorer work performance, a higher rate of sick leave, and higher health care costs. My primary goals in my research was to explore the labor market impacts of workplace health promotion and guidelines for corporate health promotion. Within health promotion, physical activity has played a prominent role. I’ve been used secondary data collection during my research. I have been performed a traditional literature analysis based on domestic and international studies. My results are suggest that the workplace health promotion has more positive labor market effects than increasing productivity and reducing absenteeism and health care costs. It is important to mention that health promotion could bring benefits to both employers and employees. Regarding corporate guidelines, there is no new approach directive other than the older literature sources. thus, it may be worthwhile to develop a new and different corporate process for effective workplace health promotion.

    Areas after mining or calamity are not amenable to immediate afforestation and require some adjustment. After removal of wood biomass, the rest of the residue is scattered throughout the area. To modify them, Several methods can be used to remove it. The optimal conditions for the planting environment and the subsequent adaptation process of the planting can be achieved by its mechanical, biological, chemical treatment. The basic prerequisite for a successful renewal of forests is their release from undesirable increases, in some cases from foams (trees) from mining waste. The area is also released when forest nurseries, seed plantations, etc. are established. The main purpose of the release of surfaces is to achieve the maximum throughput of the area for the machines to be moved. They wear during work. Wearing is a permanently undesirable change in the surface due to the interaction of functional surfaces or functional surface and wear medium. A tool that does not have any editing can go into a state where it can no longer be used anymore. An experiment was carried out in which 9 new teeth were placed on the rotor of the crusher and their wear patterns were observed. The article shows the progress of tool wear over time.

    We have studied the tensile-impact strength of the magnesium catalysed cast polyamide 6 (PA6) rods according to the EN ISO 8256:2004 standard. The purpose of our investigation was to follow: the mechanical properties of rods are mapped beside same casting technological process in case of different diameters. We have compared the received results with each other than have sought disparities. We examined cylindrical product (rod) in seven dimensional steps in diameter ranging from 40 mm to 300 mm. We have determined that the semi-finished products can be divided into two groups typically in case of their tensile-impact strengths in this size range. The tensile-impact strength is higher in case of the rods with a diameter of less than 100 mm and it is smaller in the larger dimension range. Therefore, the smallest tensile-impact strength can be established in case of the natural semifinished PA6 rods that each rod accomplishes independently of size. However, a range can be determined, which the tensile-impact strength values of product are separated according to the manufacturing size

    The concept of function is fundamental importance to the mathematics. Since the most mathematical concept is not acquired in one step [13], thus we have to take a long journey for developing of the function concept. One of the aim of this process to develop an effective concept image which have an important role in problem solution. The students decides on the basis of a concept image whether a given mathematical object is an example or nonexample of the concept. (Vinner & Dreyfus, 1989). In this paper we are looking for the answer of the following question: what are the concept image of the function concept formed of the students by the end of the primary school (8th grade) and the first year engineering university students?

    3D printing is an increasingly widespread manufacturing process. With the development of machines and materials, the technology is becoming more accessible and easier to use. However, the technology's specificities mean that it requires knowledge of manufacturing technology. In some cases, it is necessary to solidify the freshly deposited layers as soon as possible in the event of large overhangs. This can be achieved by active cooling, which in turn can affect the material properties of the part. This research investigates the effects of active cooling during production.

    Under 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.

    The height determination of control and detail points is essential during the process of planning and manufacturing in the practice of civil engineering. Planning maps are drawn for the former, while the intended plan is set out on the ground during manufacturing, and after the manufacturing the completed installation is mapped. Using the same reference system in all three steps, both horizontally and vertically, is recommended even though in some cases it is unavoidable to change from one reference level to another. Regardless of the fact that both refer to the mean sea level of the Baltic Sea, this can create difficulties, since the difference between the EOMA and Bendefy networks used in Hungary shows varying values depending on the geographical location. The aim of the analysis is to determine a constant difference regarding the analysed settlements based on the common points of the networks.

    The Ti-2Al-2.5Zr titanium alloy plate in beta phase water quench at different times of the reentry after annealing is implemented while primary phase number and size distribution of samples are obtained. This research is carried out on corrosion behavior in 3.5% [mass fraction] NaCl solution. Experimental study showed that after the beta phase water quenching Ti-2Al-2.5Zr titanium alloyed after 500 oC annealing when partial recrystallization happened. There seems to be lots of tiny dispersion in the alloy that was annealed with its samples of six-party [HCP] structure of Ti, Zr, Al phase 2 with the dimension below 100 nm. Reaching 500 oC when the rate of annealing at a primary phase of the sample at 550 oC is low 90% of the primary phase is less than 100 nm. The changing of the rule of present decreasing also triggers little difference overall. Precipitation in the process of annealing Zr [Nb,Fe,Cr] 2is less that proves to be good for corrosion resistance.

    Social innovation is not determined as a uniform definition, after a literature review can be defined as follows: social innovation is an innovative and new way of improving community well-being [2]. Social innovation can be defined and measured at micro-, mezo- and macro level similar to technical and economic innovation and plays a key role in the competitiveness. Because of imbalances arising from different levels of economic development, catching-up demand of peripheral settlements have appeared. In addition to the so-called technical innovations, the solution of social problems can be achieved by social tools, methods and new organizations. In catching-up process the local, community level construed innovative ideas and the activities of social innovation play a significant role. The expansion of the innovative areas results in different innovation processes and they can be considered as complementary processes. The social and technical innovation are closely interacting. If there is achange in the economic sphere, social change can occur. This study examines the role of local communities in social innovation at regional level and summarizes the clarifying questions of implementation. Social innovation as a new tool is able to answer daily challenges. The innovative solutions of municipalities, which means new collaborations, result sustainable, flexible and open leadership at regional level. This study will examine the role of governments (or their institutions) in the implementation and generating of social innovation, the tasks of regional innovators and social solutions and models of certain municipalities in Hungary and the European Union.

    The Polylactic acid (PLA) is compostable and natural renewable sourced plastic type. Its mechanical properties quite similar to the PET, therefore the PLA is a good alternative for strongly ruled food industrial application. The PLA only has one critical attribute – the relatively low glass transition temperature. According to the relevant literature the glass transition of PLA is in the range of 40-70°C. In light of this fact, this material can be used only in that segments of food industrial field where the packaging process temperature are under of the lower limit of Tg range. The actual Tg of a material is highly depends on the molar mass and material structure, therefore the molar mass and the structure of material should be designed according to the future requirements of application and procedures.

    The lean approach is based on the buyer, while eliminating losses, in addition to value creation and efficiency gains, it determines the direction of developments in the process. To successfully build and maintain lean, engagement and development is indispensable, but it is not as simple as changing past behaviors and attitudes. The company also realized that changes were needed, as the increased number of employees in the company, and the increase in production and the profits associated with it, made it clear that organizational development is needed. The organization development was started by SWOT analysis, and along with Ishikawa's assay, I discovered whether LEAN was necessary for the company. With Gemba, I took a look at the problems and then categorized them to designate development points.

    Leadership decision-making is important for the successful functioning of organizations, so it is necessary for leaders to understand the factors that impact their decisions. Decision-making is always the responsibility of the leader, but in a changing world, it becomes an even more crucial factor for success. Making good decisions requires time, experience, and thorough problem-solving skills. In my research, through the analysis of scholarly sources, I have identified several role factors that clearly influence the decision-making process and its implementation. Furthermore, I have developed a self-designed questionnaire to examine the decision-making role in modern organizations. I analyzed the data from 230 respondents using various statistical methods. Based on my findings, conflict management, risk-taking, and a thorough understanding of the problem strongly determine leadership decision-making processes. The ability of leaders to effectively manage conflicts significantly impacts their decisions. Risk-taking is also of key importance, as leaders need to recognize the risks associated with a given situation and make decisions accordingly.

    Performance of the domestic online commerce showed a dynamic increase in recent years and, based on the expected forecasts, this trend will be realized in the future as well. In Hungary, the number of electronic commerce undertakings is estimated to be within a range of between 5 000 and 6 000 pieces and this number is steadily increasing. Today, the opportunities offered by the internet play an increasingly significant role in every segment of the economy. In the increasing market competition, it is no longer sufficient to serve the local population. Driver of the internet commerce is a marketing activity therefore the performance measurement is a priority. The excellent result and success essentially and principally depend on the performance, in addition to luck. Performance is understood as the measurable results or, in the broad sense, the successful efforts which are made to achieve the organizational objectives. The performance measurement is a measurement process of the efficiency and economy of an activity. Its aim is to support the decisions and actions related to the operation of the undertaking. The performance measurement is not only a decision support tool but also an element influencing every level of the decision-making system; it has an effect on the actions of stakeholders. Its danger and importance are simultaneously the fact that its improper operation (application of incorrect yardstick) can result in a functioning contrary to the corporate objectives. My aim is to survey the corporate performance measurement practice, to assess the connection between the financial and operational performance as well as to analyse the connection between the performance measurement practice and the performance achieved.

    Corporate innovation can be a major factor in economic development and long-term high-level corporate performance. The position of the EU in international innovation rankings has not improved since the 2000 2009 period; though there has been a more positive trend since 2010, meeting the Lisbon goals, the EU is still not at the forefront in terms of R&D&I. Behind this process is the rapid progress of some industrially developing nations in R&D&I, as well as the relatively slow institutional development of national innovation systems in Europe. The relative lag in Europe can be explained by the frequently referred to “European paradox”, which is still unclear for methodological reasons. Firstly we consider the international ranking in innovation, then discuss one of the explanations put forth to explain this rather weak performance. We present case study that represent Hungarian experiences with corporate innovation.

    Our research is focusing to one of the most complex and important production step of flat rolled products that is the simulation of hot rolling. During hot rolling two phenomena as work hardening and the process of regeneration of crystals has strong influence for physical properties of microstructure of aluminium alloys. It needs to be taken into account in case of rolling technology steps and development. When we talk about aluminium the dynamic softening in fact it is dynamic recovery that is followed by dynamic recrystallization. It goes in the same order of magnitude rate. But in steels the recovery has only a minor effect. Hot rolled and newly modified grain structure is influenced by these dynamic phenomena. Hot rolled grain structure goes through significant changes under further production steps like cold rolling and heat treatments. But aside from these intermediate production steps the microstructure that we get after hot rolling has significant effect for mechanical and grains structure of the final flat rolled product. Proper technology planning is essential that for cellular automata simulation method can ensure useable and good solution for the simulation of recrystallization.
