Investigation of application and development of precision irrigation technology
239-248Views:403Due to the extreme weather conditions irrigation is nowadays considered an increasingly necessary factor. After evaluating the water requirements of the plant and the available water resources is necessary to decide what irrigation method to use. One of the most commonly used methods in field conditions is rain-type irrigation, of which there are several types (eg linear, winding drum). The uniformity of the field nozzles can be characterized by the Christiansen uniformity factor (CU%) and the distribution uniformity factor (DU%). The coefficients can be derived from the volume of water captured by the rain gauges. Our investigations were carried out in July and August 2019 at the University of Debrecen's Vision Plant Experimental Plant and at a linear irrigation equipment of a Nyírbátor company. The aim of the study was to compare the uniformity of water dispersion applied by conventional linear technology and precision linear irrigation technology.

Practical Application of Methods in Strategy-Based Analyzes
59-72Views:722Increasing environmental volatility is a growing challenge for companies and businesses. The speed of economic events is changing, and the risk of uncertainty is increasing, requiring business to take a new approach to strategic planning. In the design and forming of their strategy, both the factors of the external and internal environment and the analysis of their competitors can be based on well-chosen methods. We consider the review of these methods, their application in planning and educational practice. The aim of our work, in which we present the methods that underpin the strategy applied in both domestic and international practice. The analysis of the external environment illustrates the construction and applicability of an external factor analysis matrix based on traditional PEST analysis and the Porter's five-factor model. In the case of internal factor analysis matrix, we focus on the approach of method choice, and on the applicable methods, the importance of the resource-based approach, the analysis of key factors and the Porter value chain analysis matrix. The third pillar of the analysis that underpins the strategy is the matrix-based assessment of competitors. The applicability of the methods depends on the form of the enterprise, the field of activity and the nature of its activities, which is complicated by the emergence of new economic spheres (e.g.: sharing) and transformed power relations.

Transformation of the Decisional Leadership Role
26-40Views:389Leadership 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.

Analysing the Possible Connection Between Dark Triad Personality Traits and Ethical Attitudes of University Students
57-67Views:491In our paper we examined the possible connection between the Dark Triad personality traits and ethical attitudes among university students. The analysis of both topics has become the focus of interest in the past decades. Researchers consider the impact of many factors in the background of ethical attitudes and behavior. Among other things, personality is also a potential factor. The Dark Triad personality means the coexistence of the socially undesirable narcissism, Machiavellianism and psychopathy. Such people are characterized by self-love, aggression, the lack of guilt or conscience, so they are less likely to have ethical attitudes. In our research, this connection was examined by a questionnaire survey conducted among first year students of University of Debrecen Faculty of Natural Sciences and Technology and Faculty of Economics and Business. Respondents completed the validated Dirty Dozen questionnaire which was developed to measure Dark Triad personality and a questionnaire adapted from Lozier's research in which respondents were asked to evaluate school situations whether they are ethical or unethical and to what extent they are unethical. In our research, we were looking for significant relationships between the strength of the Dark Triad characteristics and the ethical judgment of situations. We also analyzed the differences between men and women and students of the two faculties.

Requirements for Multicultural Competencies Defined by a Focus Group
44-56Views:358Globalization, the spread of multinational companies and the enormous development of information technology can lead to a new trend in employers’ requirements. However, being employed by an international company is a real possibility for any employee in any part of the world. Even if they do not have to work abroad, employees may have to function in a multinational environment in their home countries. A favourable combination of intercultural competencies is a key factor in the selection and development of employees. A possible way of measuring these competencies can be the Multicultural Personality Questionnaire (MPQ). First of all,on the employers’ part, it is important to clarify the exact requirements and competencies (dimensions) to be able to draw up an ‘ideal profile’. We prepared two versions of the MPQ (91-item; 5-dimensional) and used them to test employers’ requirements in the selection process regarding the dimensions of cultural empathy, open-mindedness, social initiative, emotional stability and flexibility. This study describes the results of a focus group interview, which took place in 2017, revealing the importance of multicultural competencies from the employers’ point of view and examining the conditions of the adaptability of the two questionnaires. We used the focus group method to find out in what conditions the questionnaires canbe used in a selection process. What possibilities and limits are therefor using the direct five-dimensional questionnaire? What aspects do we need to take into consideration in expressing and interpreting the requirements in the results of the test?

The significance of analysing potential conflicts in the sales-marketing integration
41-59Views:263Our research aims to identify the critical interfaces between sales and marketing that need to be improved in order to ensure productive cooperation. The relationship between the two departments is full of conflicts and interdependencies. The improvement of communication is of strategical importance, as it is key to staying competitive in the market. The effectiveness and quality of the sales-marketing cooperation is a key factor that is negatively affected by personal and organisational factors as well as a lack of information and conflicts. In addition to the key factors of managing the sales-marketing interfaces, we have also identified the actions that can promote their improvement, including strategic and organisational roles and responsibilities. Our empirical research results show that regular information exchange, more common and interdisciplinary meetings, and a clearly communicated and implemented corporate vision have a positive effect on the coordination and integration of the sales and marketing departments. Consequently, management is reponsible for establishing a corporate vision, i.e. a comprehensive management culture that is clearly communicated across the board in order to increase the employees’ sense of belonging. Of all elements of management culture, the most important factors are coordination and the establishment of a common strategic sysyem. All in all, corporate profit, which is of key importance to the employer, is largely dependent on the successful integration of the sales and marketing departments, which can be achieved through the implementation of the above factors.

Numerical Model Analysis of Natural Gas Combustion Burners
67-71Views:332Traditional 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.

Digitalization Process by Agricultural Companies, or the Results of a Questionnaire Survey
625-636Views:397The term “information society” first appeared in Japanese social science in the early 1960s (Z. Karvalics, 2007). The interpretation of the concept has undergone significant changes over the past decades, showing that dynamically developing societies, which are undergoing constant changes due to the rapid development of information, information management and the dynamism of the digital world. The close relationship and connection between information and information technology has become a fundamental factor in the societies of today, the organizations life, which generates inevitable, sometimes serious debates and profound changes. Economic operators must necessarily be resilient to technological change. We should think of the time of the Industrial Revolution, when modern weaving machines flooded the factories. Otherwise, a resilient organization will not survive in an evolving and ever-changing dynamic economic environment. Of course, this is true of agriculture as well, just as it is for other sectors of the national economy. On the one hand, my assumption on the basis of which my questionnaire was compiled was that enterprise management systems are increasingly used by enterprises in agriculture due to the diversification of activities. At the same time, I assumed that the size of a business could influence the use of information technology (hereinafter IT), so I hoped that my research would provide reliable data on this as well.

Topology Optimization of Acetabular Cup by Finite Element Simulation
22-34Views:649Hip replacements typically consist of a four-part piece. Our research will focus primarily on the acetabular component. Several different types of materials can be used when creating a hip replacement implant ranging from plastic to titanium. Different materials are used to accommodate for allergic reactions or circumventing potential health risks. Aside from the material, the size of the components plays a factor in terms of durability; a larger diameter head might avoid dislodgement though it could increase wear and tear on the stems through constant friction. A patient’s force applied to the hip replacement is usually measured through a number of physical assessments. Finite element analysis (FEA), a computer-based method of data observation, allows for us to accurately simulate hip forces and their impact on the hip replacements. Through this, it becomes easier to predict and calculate the performance of specific designs. Generative systems can also be used to support performance analysis and optimization through assessing a multitude of cases, many of which apply in real-world scenarios. By applying both systems, we designed and modeled an acetabular cup that when measured decreased the mass from 129 grams initially down to 52 grams, a 60% decrease in total mass. Furthermore, the design we created lessened the trauma on the piece through distributing force across the entirety of the piece rather than specific segments only. This shows an increased durability and life expectancy when compared to usual acetabular cups.

Opportunities for Keeping Talent Highlighting Career Needs
31-43Views:599Organizations should focus not only on finding a workforce, but also on finding a talented employee and to be able to keep them. That is why we considered it important to pay attention to talents and careers. In this paper, we attempt to identify those factors which are important for career prospects among future employees and those already in the workforce. Moreover, we want to identify the factors which those who are already employed consider to be factors influencing their career prospects. We conducted a survey of students using questionnaires. 116 questionnaires were completed, of which 73 were filled in by BSc / BA students and 43 by Msc / MA students. We sought to discover to what degree the respondents considered the career factors we presented them with as influencing their ability to acquire an ideal job, as well as to what degree the same career factors would be able to assist them in their future career advancement. Presently, in their roles as students seeking gainful employment, important factors include perseverance, diligence, knowledge, and aptitude, all of which the respondents feel will become even more important in making their later advancement possible. At present, they do not consider the support of companions / partners and morality important; but they consider the support they receive from their colleagues to be a factor which grows in importance over time. In the questionnaire survey of employees, we were looking for two answers. On the one hand, which factors are important in shaping their careers, and on the other hand, at the workplace, which factors were related to employee retention and satisfaction. For their careers, they consider it important to have diligence, morality, and the support of colleagues. These results are similar to the views expressed by the students. However, those who already work consider ‘kissing up to the boss’ to be more important for their advancement possibilities than the students did. The responses concerning factors contributing to successful employee retention brought interesting results. Factors that are most commonly fulfilled, such as a good co-worker relationship and the working relationship with a leader, are barely above the average score of 4, which is actually a result that is above average. Medium results include the realization of independence, challenging work, fair pay and career prospects factors, all of whcih would be vital for talented people to experience flow in their careers. In the long term, leaders and HR professionals need to pay attention to take calculated, equisite steps to keep talented workers.

Company Valuation of an Entity Operating in International Accounting Environment
320-331Views:735Company and asset valuation plays a major role nowadays. Determining the company’s value is a key factor for management in appropriate decision making, and it is a necessary step for individuals who wish to invest and for investors. There are numerous models which utilize different methods for company valuation. In our study we based our valuation on the McKinsey model for a company in an international accounting environment. In the study we present the main attributes of the McKinley model, its structure, which includes the main steps of valuation. We put a special emphasis on the calculation of free cash flow, future balance sheets and profit and loss accounts anticipation as well as future turnover, which highly influences the changes of data in the future reports thus in the company value. The McKinsey model is a discounted cash flow model, in which the company value and the consequent future cash flow can be determined as present value.

Experiences of Innovation Projects in the Light of the „European Paradox”
563-578Views:242Corporate 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.

The Empirical Examination of Different Customer Types
92-100Views:274The proper knowledge of customer types is essential for a well functioning company – regardless of its size. In current research we wanted to identify and characterize the particular customer groups with involving 302 persons. During the examination we measured the attitudes of these participants with the help of a statement range based on Kotler’s classical customer types. For the identification we made factor- and cluster analysis, and we could separate five different factors. They received the names of Angry, Definite, Discursive Passive, Experience Shopping and Indefinite - based on some related statements. After the cluster analysis – along these factors - we could separate four different groups: Young Impulse Shoppers, Outspoken Definites, Negatives and Born Customers. Each and every group requires different communication, sales attitude and service morals.
