Sustainability, sustainable supply chain management
322-328Views:868With the rapid development of the world economy, the growing scarcity of natural resources and the degradation caused by pollution, environmental protection has become a major concern for countries and regions of the world. Sustainability is a common subject in many parts of the world and the various research areas among policy makers, journalists, scientists, universities and social debate. It is generally accepted, that companies also play an important role in addressing the challenges of sustainable development. In this role, making a key challenge to balance often conflicting pressures caused by sustainable development, that is, the level of corporate economic performance against environmental deterioration and social disruption. Effective integration of sustainability principles into companies requires action beyond the borders of organizations. The issue of sustainability is becoming more and more prominent in corporate governance. One of the most important area of supply chain management is for companies to gain a competitive edge in the market. This has a significant impact on the natural environment, and there is a growing need to integrate environmental thinking in supply chain management and processes, which is why companies are increasingly focusing on sustainable development, taking on more CSR initiatives and achieving a greener supply chain. Sustainable and green supply chain management practices have been developed over the past decades, trying to integrate environmental considerations into organizations by reducing unwanted negative consequences for the environment of production and consumption processes. In this article, I have examined the issues of sustainability and sustainable supply chain management, mainly based on descriptive secondary literature.

Estimation of the Potential Runoff Quality Improvement as a Result of Applied Green Infrastructure Measures in a Hungarian Town
34-41Views:220Green 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.

Development Lies in Corporate Processes
358-369Views:254Nowadays, our rapidly evolving world is characterized by constant change. Organizations need to be prepared and responsive to these systematic changes to compete in the marketplace. Today nothing is constant or predictable because the organization is driven by the "3 C" force (customers, competition, change). Rapid adaptation to ever-changing circumstances requires companies to move from structured organizations based on traditional functions to process-based management. By using state-of-the-art process management procedures, organizations can be made transparent, analysable, measurable, and continually improving, and help companies increase their performance and organizational flexibility, and reduce costs. It also helps to recognize when it is necessary to change a process for an effect. In the event of creating well-organized processes, companies are more responsive to changes in the market, allowing them to operate more efficiently, and to carry out development activities easier. Nowadays, development as a new framework focuses primarily on digitalisation, which is challenging for companies to adapt but without this, they would be left behind in the competition. These challenges require radical changes and transformations in the lives of many organizations, which are difficult to achieve. With the development of process-based enterprise management, not just multinational companies can improve their operation, but small and medium-sized enterprises can also move towards digitalization thus inducing development for not only their own but for the economy as a whole.

The Alternative Use of Straw
331-343Views:140The problem addressed in this work is to examine the feasibility of using straw in innovative and alternative ways, focusing on aspects of cost sensitivity in subject areas of building investment and energy compsumption. I analysed the energy efficient performance of a straw bale building and compared that with those of a conventional construction, a newly-constracted building and a passive house. In my study I assessed the figures of costs of emboided energy, primary energy consumption and carbon dioxide emission. I made calculations in terms of energy costs for a lifespan of 50 years. Considering that straw-bale construction uses an excellent and sustainable insulation material, its energy use is by 25.38% less than that of conventional construction.

A study of pressure-sinkage relationship used in a tyre-terrain interaction
186-199Views:170The vehicle applies a normal load to the terrain, which causes sinkage and motion resistance. To forecast the normal pressure distribution on the interface of a vehicle–terrain and the tractive performance of a vehicle, the response of the terrain to normal load (which is characterized by pressure–sinkage relationship equations) must be measured. This paper presents the common conventional pressure sinkage models used in terramechanic and the modification that happened to this models. In addition the features of the new models.

The Legal Aspects and Challenges of Managing Workplace Mobbing
1-9Views:711Workplace mobbing (psychological harassment) can be a great challenge for the management of any organization. Although the phenomenon has been discovered for quite some time, there is still no unequivocal definition, and therefore preventive and managerial actions are rudimentary. It is clear that mobbing affects not only on the individual employee, but the whole organization. The reduction of commitment of people working in this environment (and not only those directly affected by it) may have a detrimental effect on the performance of the organization. I will present a legal case study to highlight some of the general and procedural shortcomings of mobbing at the workplace.

Project Risks and Risky Projects
164-189Views:355Projects are key drivers of organizational change, both their failure and success can have significant impact on the organizational performance. Risks may arise throughout the entire project life cycle. Managing these and initial project planning uncertainties is an important task of Project Management. The study describes the application of traditional project management tools and methods in risk analysis, -evaluation and -treatment based on modern project and risk management standards and recommendations. The authors also examine the link between classic project management objectives (project time - resources – scopes) and risk-based decision-making. The different scale and scope of projects call for different responses to the associated risks. The study highlights the possible role of the ISO 31000 risk management standard package in project risk management. The authors analyse the risk management of the different projects on the basis of processing relevant literature, including the relationship of the project stakeholders to the risks. R&D, agile projects and project portfolios have specific and complex risk exposures, but their project management can provide several „hidden” risk analysis and - treatment functions.

The Correlation between LGBTQ Tolerance and Economic Development in Europe
31-51Views:347This study analyses the relationship between LGBTQ tolerance and economic development. It uses various indices measuring tolerance and economic data of 48 European countries. Based on previous literature I outlined how economic progress is supposed to have an impact on the social inclusion of marginalised groups. Also, a number of empirical reports are cited providing substantial evidence that tolerance can too shape economic performance. The main aim of this paper is to confirm that these findings in fact hold water in Europe. Having examined the regression analysis of GDP per capita and tolerance, as well as HDI and tolerance, I found that the modernisation theory proved valid on my sample. The other component of my analysis focusing on the sway of social inclusion over FDI showed that more tolerant states attract more foreign capital. These results led me to believe that economic progress and LGBTQ inclusion are interrelated, thus the latter should be considered upon forming policy.

Numerical Model Analysis of Natural Gas Combustion Burners
67-71Views:159Traditional power plants still the dominating power source for all the major industries and powerdemanding facilities, the most crucial facility for the whole plant operations is the industrial boiler which generatessteam, heating energy or electrical power. Boilers generate energy by combustion. The improvement of combustion efficiency could greatly influence the energy consumption and will make the boiler more efficient and cleaner (less emissions), that’s why it is important to understand the combustion and thermal flow behaviours inside the boiler. Beside experimental testing, computational work nowadays becoming more and more important due to lower cost and acceptable accuracy with minimum error. With numerical calculations method, the computational model created by a Computational Fluid Dynamics (CFD) software could reduce a lot of trial and error on experimental work. In this paper utilizing the ANSYS FLUENT 19.1 software to make crate the combustion model. The ratio of air to fuel mixture, the equivalency factor, mass flow rate of the mixture, velocity, mass fractions of the mixture components (fuel and air) and their temperatures will serve as the input parameter while the exhaust gase component mass fraction, temperature, mass flow and velocity will be monitored.

The Factors of Digitality and Sustainable Competitiveness in the Domestic Context
217-226Views:184The recovery of international relations and the development of technology are in correlation with the increasing globalization tendencies. These processes increase the interdependence of countries, but also the competition between them. The factors of competition are constantly changing and being revalued. As a result new elements appear in addition to the traditional elements, and there are assimetries between existing components. The economic performance of a country increasingly depends on the knowledge and technology, its economic success on the use of knowledge. The purpose of the study is to present and analyze the proxies that define and shape the role of Hungary by IMD Competitiveness Research Center and by the complex indicators developed by Korea-based SolAbility. It also draws attention to all the factors that will significantly effect our country's economy in the future.

The Role of Employee Participation and Resistance in the Success of Change Management
22-30Views:262Successful change in the lives of organizations has played a particularly important role in the recent turbulently changing decades, and leadership-follower relationships need to be addressed in order to maintain performance. Participation should be ensured for members of the organization and emerging resistance should be addressed. The subject of my research was to examine whether the assessment of the success of change is influenced by the provision of opportunities for employees to make suggestions and their opposition to change. By performing chi-square tests, I came to the conclusion that if the opinion of the worker is heard, they are more likely to judge the change to be successful, however, the manager is not affected by the involvement of the employees in this. However, there is a correlation between employees' resentment to change and the success of change, both from the employee and managerial side, change is more unsuccessful if resentment develops. Based on the results, both factors are important. It is worth drawing the attention of managers to the need to ensure participation, as failure to do so can lead to dissatisfaction among employees, which can also have a negative impact on the success of the organization.

Role of Grants for Tourism Purposes in Development of the Northern Great Plain Region
365-376Views:181Aim of the treatise is, based on main macroeconomic indicators, to present the development of the Northern Great Plain region and the amount of EU grants received, including the ones for tourism purposes, as well as to examine the effects of grants. Based on the data, it can be concluded the region received significant grants during the years 2007-2013; it is in last place in view of the economic development but has achieved better performance in several areas. It is difficult to examine the accommodation and food service national economic sector independently: in one respect, it develops by the combined impact of several other areas, on the other hand, the tourism-related developments become usable for other sectors as well, new enterprises and investments are launched, at the same time, not only the companies’ but the municipalities’ revenues from tourism are increasing. Based on the statistical data, attention will be drawn to the fact that the outcome of developments is just moderate in the area of catering and tourism in the region and has a different rate by county.

The impact of realization of solar power plant installation requests in Mandatory Purchase (KÁT) system on the electricity supply of Hungarian settlements
54-60Views:108The support system of renewable energy production was changed in Hungary in 2017. The legislator created the Mandatory Purchase (KÁT) system earlier to encourage the electricity production from renewable energy sources and waste. The Renewable Energy Subsidy System (Metár) changed the Mandatory Purchase (KÁT) system from the 1st of January in 2017. It had been known before Metár came into force that the supported period in the Matár would be only 13 years while it was 25 years in the KÁT. Therefore, a real rush started for the KÁT support licenses in 2016 in order to make more beneficial contracts by the investors. At the time, the Hungarian Energy and Public Utility Regulatory Authority (MEKH) released a record amount of licenses (more than 2000 pieces) to build solar power plants under 500 kW performance. This is more than 1000 MW total power. This paper searches the answer how this solar power plants will influence the level of self-sufficiency of the Hungarian settlements in the electricity supply if those are realized. Hereinafter, we will analyze the possible impact of these solar power plants in the settlement electricity self-sufficiency.
