Grants Rating Due to Operative Public Procurement Law and by Applicable Regulations
129-138Views:139The aim of new Public Procurement law is to ensure the efficiency of appropriation public money. On new legal regulation public procurement procedures become significantly faster and transparency and competition is increasing. The law entered into force on the first of November in 2015, but has been modified several times since then. A year ago, the National Parliament adopted the law on State Program Evaluation cover. The legislation aims to make the European Union resources for projects in an objective, transparent and independent from the interests of the operators assessment system.

Price Analysis Practices in the Pig Sector
1-12Views:65The analysis of sales prices has become a particularly important topic in pig production research, including statistical analysis. With globalisation, we can say that today we are talking about a sector constantly exposed to the effects of the world market. It is also worth pointing out that, compared with other sectors, the impact of external regulation and influence is less pronounced. Thus, the aim of the present research was to identify the journal articles published on the subject of price analysis and, on the basis of these, to establish the correlation with the methodologies often used. It examines the spatial location of price analysis. The results obtained show that the practice of price analysis is mainly carried out in the context of market leading countries, usually on the basis of a cross product chain issue. The research shows the emergence in recent years of increasingly sophisticated methodologies that allow more accurate conclusions to be drawn, while also facilitating planning from a practical point of view.

Justification for the Olympic Reform Package Based on Good Practice
Views:236The Olympic Games have always been the pinnacle of sport and achievement. The modern Olympics are held every four years, and the venue is chosen from among the cities that apply. In my research, I wanted to find out the reasons for the decline in the popularity of the Games. To answer this question, I looked at 2 successful Olympics (2000 Sydney, 2012 London) in the hope of identifying success factors that could be adapted to other host countries. I conducted secondary research, reviewed related international and national research, and the available economic data. During the document analysis, I found that the expected costs of organising the Olympic have increased significantly over the last two to three decades, and under-planning is a common feature. As a result of the research, I have found that the most important pillars of successful organisation are a proper organising committee, comprehensive opportunity and risk analysis, accurate planning, sustainability in planning, continuous cost control, private sector support, and the work of volunteers.

An Overview of the Situation of SMEs in Hungary in Catching up to Industry 4.0
72-80Views:123Since I have been working I have been in contact with small and medium-sized enterprises (SMEs) and large companies in various ways. I have thus been confronted with the disadvantages of the former in terms of the introduction and use of 4IF technologies. Yet most of them are aware that to remain competitive in the market, they cannot avoid digitising their operational processes to some extent. I have also found that this mainly depends on the characteristics of the organisation; for example, its orientation. Domestic SMEs are therefore currently at a competitive disadvantage in the market. However, there is no information on whether there is a trend towards development and where they themselves should develop. This would help them to develop the right, achievable vision for the future, coupled with a feasible business strategy.

The Role of Statutory Notes in Informing Market Players
202-212Views:326The conduct of numerous economic operators is influenced by the globalization accelerated nowadays. In this connection, it can be certainly said that the globalization affects the accounting regulation as well. In our country, the business entities falling within the scope of the aforementioned regulation are subject to Act C of 2000 on Accounting, according to which the prepared reports shall provide the external and internal stakeholders with information ensuring a true and fair overall picture of the business entities’ property, financial and profitability situation as well as future plans. Over the recent years, the reason of changes in the Accounting Act was the harmonisation with other laws thus the main part of the change in year 2016 was the obligatory transposition of the Directive 2013/34/EU into the domestic law system as well as the completion of the previous deficiencies. These changes influence the system of accounting records that has been already established. In my treatise, I will highlight a part of the report i.e. the Notes providing text information in addition to the numerical data. Furthermore, the changes in Act of 2016 on Accounting will be presented with respect to the Notes.

Teaching the Analysis of Newton’s Cooling Model to Engineering Students
63-68Views:91To apply mathematical methods to physical or other real life problem, we have to formulate the problem in mathematical terms. It means that, we have to construct the mathematical model for the problem. Many physical problems shows the relationships between changing quantities. The rates of change are represented mathematically by derivatives. In this case the mathematical models involve equations relating an unknown function and one or more of its derivatives. These equations are the differential equations. In this article, teaching the analysis of Newton's cooling model to engineering students is presented as one of the applications of separable differential equations.

Evolution, Place and Role of Controlling in a Business Organisation
466-477Views:973The development of controlling can be traced back to the beginning of 20th century. Thus it has one century of continuous scientific development. Controlling has been applied in fields such as finance, manufactureproduction, and trade sales. In financial accounting different activities have been formed for planning and accounting costs and performance. These activities were integrated by management accounting, which serves the ever growing information needs of the management. In addition to the operational functioning of growing and diversification companies controlling covers even the strategic level. The primary focus of controlling activity at 21st-century businesses is to improve organisational performance. Previously there were differences between the German and Anglo-Saxon trends. According to the German trend controlling is a set of instruments that provides the required information needed for management decision-making and based on it planning, monitoring, and controlling activities could be achieved. Furthermore, the German trend considers that a particular department is responsible for controlling activities. Conversely, according to the Anglo-Saxon conception controlling is considered as a part of management and managers are responsible for efficient allocation of resources, the so-called „management control”, carrying out planning and controlling tasks at the same time. Some differences can be recognised between the two conceptions about where is controlling placed in companies within the organisational framework. However, it can be stated as a fact, that management and controlling are inseparably linked, and the aim of both fields is to increase the performance of a company.

Sport, the Remedy of Stress
69-78Views:2420The study examines the relationship between mental health, resilience and perceived stress among leisureand competitive athletes. Three questionnaires (Keyes Mental Health Continuous Scale, Detected Stress Questionnaire, and 10-item CD-RISC Questionnaire) were studied, filled out by a total of 436 people, of which 297 were competitive athletes and 139 leisure athletes. The main question of my research was whether there is a difference between these three variables, and how resilience and perceived stress affect three factors of mental health, athletes in leisure and competition. The results show that for all variables the athletes of the competition achieved a better average value than the leisure athletes, and I could show a significant difference in the mean values in the case of the emotional and social well-being variables. Moreover, perceived stress had a greater impact on emotional well-being, while resilience had a positive effect on psychological and social well-being.

Environmental Index and Environmental City Resilience Index calculation for Four Settlements in Szabolcs-Szatmár-Bereg County and Four in Győr-Moson-Sopron County
17-29Views:110Globalization and urbanization pose a number of challenges for different settlements. Stakeholders seek to cure global problems through sustainable projects. Since the Brundtland Commission's definition of sustainable development in 1987, the approach to sustainability has permeated all dimensions of the economy, including the environmental dimension. In Hungary, IBM conducted a study (Lados - Horváthné Barsi, 2011), in which the search for green, sustainable solutions defined in the definition of a livable city plays a key role. The characteristics of sustainable cities, that they are resilient to disasters, return to equilibrium after a shock has occurred (Seeliger, Turok, 2013). Resilience can also be mentioned as one of the pillars of sustainability. In a UN-Habitat statement, resilience refers to the ability of any urban system to withstand and recover from multiple shocks and to maintain the continuity of its services (OECD, 2018). In my study, I would like to present the results of the environmental index and the Environmental Urban Resilience Index (EURI) of the four largest cities selected on the basis of the population in the easternmost and westernmost counties of the country.

The Global Electric Car Industry and the Related Indirect Emission
Views:518Our planet tries to create a more environmental friendly transport. Related to the car purchases we can determine the consumers’ attitudes have changed in the last years and we can say that the electric cars have become one of the most significant participants in the industry. In one of his investigations Christopher Buchal realised electric cars can burden the environment with more than 11-28% than the avarage engine cars. It is possible if we make difference between direct and indirect emission, because the direct emission of the electric cars is zero, but the indirect emission can be really high related to the power generation. My goal is giving a real picture about the electric car industry and presenting my suggestions for the future.

New Research methods of Sales-Marketing Interfaces
160-183Views:336The energy invested in research in this topic is justified by the fact that the lack of optimal integration between SM (sales-marketing) can negatively affect overall corporate efficiency. The aim of this article is to present possible research methods that can reveal the impact of selected indicators, such as information exchange, coordination, vision and communication, conflicts, on the operation of the SM interface, according to Hungarian and foreign employees of international companies, and how they affect sales and marketing collaboration between pharmaceutical companies (PMC) and non-pharmaceutical companies (NPMC). It also attempts to demonstrate how the Partial Least Square (PLS) path modeling technique can provide valuable information on the consequences of management activity, and how the methods provided by Voyant Tools provide further research through quantitative analysis of qualitative data on the marketing sales interface (SMI), they can open up opportunities. The PLS-PM modeling technique was used to explore the relationships between the selected factors and possible hidden variables. These results clearly demonstrate that there are factors that influence SM collaboration that operate differently in PMCs and NPMCs, and that nationality differences can have a significant impact on how employees evaluate factors that affect SM collaboration. Of the methods we selected by Voyant Tools, the t-SNE (t-Distributed Stochastic Neighbour Embedding) tool proved to be the most sophisticated analysis, allowing the deepest analyzes by exploring relationships between groups of terms. -
Globális kihívások a mezőgazdaságban
195-205Views:239Jelentős globális kihívásokkal kell szembenézni napjainkban a mezőgazdaság tekintetében. A természeti erőforrásokkal megfelelően kell gazdálkodni, hogy idő előtti kimerülésüket elkerüljük (erőforrás gazdálkodás). Az embernek szüksége van a természeti erőforrásokra, –fémre, ásványi anyagra, fára, termőföldre, élelmiszerre, levegőre és vízre –nem túlozva ezek az élet nélkülözhetetlen feltételei. A probléma, hogy az emberiség nagyobb mértékben éli fel ezeket az erőforrásokat, mint ahogyan az természetes módján újratermelődne. A biológiai diverzitás és az ökoszisztéma megőrzéséhez és fenntartásához a növény- és állatfajok védelme elkerülhetetlen. Ha elpusztítjuk környezetünket, akkor a jövő helyzete, az emberiség léte kerül veszélybe. Egyes előrejelzések szerint 2050-ben a mai erőforrás kitermelés ötszörösét fogjuk elérni. Egyes ökoszisztémák 60%-ára igaz, hogy az erőforrásait már jelenleg is túlzott mértékben használjuk ki, gondoljunk csak a halállományra vagy a mértéktelen esőerdei fakitermelésre, ami köztudottan baljós feltevéseket vetít előre a levegőszennyezésre nézve. 2050-re az emberiség 30%-os növekedését prognosztizálják a kutatók, ami 9 milliárd embert jelent. A népesség több mint 70%- a fog városban lakni, ami újabb területeket fog elvonni a természetes élőhelyekből. A világnépesség növekedésével az étrendben is jelentős változás fog bekövetkezni, elsősorban a magas hozzáadott-értékű élelmiszerek irányába tolódik el a fogyasztási szerkezet. Ez a növekedés azt eredményezi, hogy az állattenyésztés takarmányigénye nő, ami földhasználatban indukál változást. Az előttünk álló út egyértelmű és világos, sokkal hatékonyabban kell gazdálkodnunk a természeti erőforrásainkkal. Továbbá ezeket úgy kell kitermelnünk/előállítanunk, hogy a környezetet tovább ne romboljuk, a jelenlegi állapotát ne rontsuk. A globálisan követendő cél az lenne, hogy mind kevesebb erőforrás felhasználásával több értéket állítsunk elő. Már a nyersanyagok kitermelésétől kezdve óvni kell a környezetet, és ezt folytatni az előállított termékek felhasználásán keresztül egészen addig, amíg esetlegesen hulladék nem keletkezik belőle. Itt kerül előtérbe a folyamatos terméktervezés és – fejlesztés, valamint a pazarló eljárások visszaszorítása az anyagtakarékosság visszaszorításával. A jelenlegi gazdaságnak törekednie kell a fenntartható jövő elérésére.

The Comparative Analysis of the Microbial Communities of Activated Sludge
87-101Views:145The composition of the microbial communities in the activated sludge was thought mostly chaotic and unpredictable, but due to the new studies and breakthroughs in the past decades, now it is known that specific, accidental and non-accidental factors are responsible for the structure of the microbial community. The aim of the study is to compare the microbial communities of activated sludge of one large and two small wastewater treatment plants. During our research 14 months of data were processed. After the sample analysis and data processing, the diversity and seasonal changes of the community structures revealed. The results of the statistical analysis show that the larger system has more diverse community structure.

Opinions of Higher Education Students about Internships and Working while Studying
286-297Views:339The importance of working while studying in higher education has a globally growing tendency, and Hungary is not an exception. The demand for the opportunities of student employment has been recognized not only by the students but also by the policy makers of higher education, leading to the introduction of solutions like the obligatory internship semesters or the dual training programs. The current study contributes to the better understanding of this field through the analysis of a database from a questionnaire survey conducted among bachelor students from seven majors of the University of Debrecen during the Fall semester in 2015 (N = 589). The main findings suggest that the students mostly consider the internships as an investment into their future career while the short term compensation and the personal interests have a lower importance for them. About 75% of the students would be willing to work not more than 20 hours a week, and most of them would look for ‘official’ studentwork. For working, they would sacrifice the time connected to the following activity-areas (relative to the other activities in the list, and in descending order): time for leisure (this is the most likely to be sacrificed), for sport, for friends, for family, and for learning (this is the less likely to be traded in for working hours). Willingness to work (measured in daily working hours) seems to be connected to the following factors: major, year of study, how important the activity areas are considered compared to working (learning, family, friends, sports, leisure), and the importance of finding a personally interesting internship.

The Possible Job Creation and Job Destructive Effects of Technological Development
53-61Views:310Throughout history, technological change has often provided the basis for employee anxiety. Between 1811 and 1816, a group of workers in England who called themselves "Luddists" destroyed machines, because they thought it would endanger their workplace. 19th-century thinkers and economists such as Karl Marx and David Ricardo predicted that mechanizing the economy would ultimately worsen workers' conditions, depriving them of a decent wage. Over the last century, John M. Keynes (1930s) and Wassily Leontief (1950s) have expressed their fears that more and more workers will be replaced by machine solutions that will lead to unemployment. In recent years, Brynjolfsson and McAfee (2014) have argued that existing technologies reduce the demand for labor and put some of the human workforce at a permanent disadvantage. However, there are a number of compensation mechanisms that can offset the initial displacement effects of automation and process innovation in general (Vivarelli, 2015). First of all, while workers are being replaced in industries that introduce new machine technology, additional workers in new industries are needed. Second, automation (and process innovation in general) reduces average costs. Acemoglu and Restrepo (2017) found that this results, on the one hand, in the effect of price productivity (“priceproductivity”) (as production costs decrease, the industry can expand and increase labor demand); and, on the other hand, it leads to economies of scale in production (the reduction in costs due to automation leads to an increase in total output and increases the demand for labor in all industries). Similarly, Vivarelli (2015) argues that lower average costs can result in lower prices (if the industry's market structure is perfectly competitive), stimulate product demand, or result in extra profits (if the industry's structure is not perfectly competitive). If these extra profits are reinvested in the company, this investment can create new jobs. The presentation intends to present these counterbalancing cases and to provide real examples based on the literature.

Analysis of labor consumption in Hungary in the last 5 years
127-137Views:139The main idea of my research was the statement of the President of the Hungarian Fruit and Vegetable Interprofessional Organization and Product Council (Ferenc Apáti), according to which the main obstacle to the future development of horticulture and the development plans of horticultural enterprises is capital shortfall factors). The employment of seasonal workers in the production of grapes and fruit and in horticultural farms is of the greatest importance. As a result, in my research, I examined the use of labor by those working in agriculture over the past 5 years. I reviewed how the coronavirus has affected the time spent by seasonal workers at work in the recent past. Since there are a lot of work phases in agriculture where there is a temporary use of labor, I considered it important to get around this topic better. As seasonal agricultural workers are often able to reach their agricultural jobs through travel and border crossings, government regulations (travel restrictions, border closures) have made it more difficult for these people to access jobs.

Design and Implementation of BHN Testing Equipment To Measure Remaining Stress Of Wheelset Parts (Tie Rod and Stabilizer Bar)
337-341Views:181Nowadays in the automotive industry both production and service, requires accurate lifetime calculations. Today we have big amount of theoretical background and nowadays the importancy of technical and industrial databases become more and more important. By materials scientific and fracture mechanics aspects are well covered, but the remaining stresses which are present in every step of production, we can not clearly identify the origin of them. There are different paralell methods to mesure them, but the application of different methods are depending on the engineers, and their expreiences at the company. This part of the analysis is not standardised yet, so there are differences even in the same company.
