Comparison of R&D innovation indicators of the visegrád group
162-172Views:74Innovation is a crucial strategic issue not only for businesses to maintain and improve competitiveness, but also has paramount role at a macroeconomic level how a national economy is able to contribute to the national division of labour. Innovation and research and development are particular and even more crucial in post-socialist countries which are trying to catch up with Western Europe in an economic point of view. We compared countries in the Visegrád Group in the study regarding their innovation indexes, R&D indicators and corporate innovations. These indicate that countries in the Visegrád Group are lagging behind the European Union. The Czech Republic ranks the first place in almost each aspect among the countries in the Visegrád Group. As for time series indicators, there is a steadily improving tendency in R&D. Regarding measuring innovation and R&D, it can be concluded that perfect method and scorecard are not available, indexes based on varying methods may generate different results and decision taking only one index into consideration cannot be made in business practice. In my opinion, R&D indicators are dominant to a large extent in comprehensive innovation indexes that might be misleading in the assessment of innovation (particularly in corporate innovation).

Current Challenges of Personal Branding
485-494Views:846The purpose of this study is to highlight the importance of collaborating with influencers as one of the most recent marketing tools. This article is intended to help brands and influenceres in critical situations, such as problems encountered in measuring performance or finding the right strategic partners, as mentioned in the literature. In the future – among the many potential research areas – we plan to study the self-branding of athletes and find key factors that distinguish influencers from other people.

CSR Activities of International Ice Hockey Clubs
Views:149Worldwide there is a growing ephasis on corporate social responsibility (CSR) and became increasingly important for sports organisations too. At the same time the international research and study numbers increasing, which examine the practical application of the CSR concept in sport.
The study provides an insight into the importance of CSR activities in foreign hockey clubs, especially in Finnish and Swedish hockey clubs with long-rooted hockey cultures, through expert interviews and their analysis. We get an answer for how they have integrated environmental activities and helping society into their every day live. Good examples from abroad are provided, ont he basis of which this study can help the hungarian sport clubs who want to develop their organisation through CSR activities.

Topology Optimization of Acetabular Cup by Finite Element Simulation
22-34Views:417Hip 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.

Effects of TIG Reheating on Duplex Stainless Steel Weld Microstructure
295-302Views:141Duplex stainless steels (DSS) gaining their excellent mechanical properties and corrosion resistance due to their austenitic-ferritic microstructure, ideally in the same amount. However, to keep this ideal phase ratio during arc welding is very difficult. Generally, the arc welding processes will result in more ferritic microstructure in the weld metal and in the heat affected zone, due to the rapid cooling. The ferritic microstructure can cause chromiumnitride precipitation, because the nitrogen solubility in ferrite phase is very low below 700 °C. These chromiumnitride precipitations can cause loss of corrosion resistance and mechanical properties. However, during subsequent reheating, the chromium-nitrides can dissolve and act as a secondary austenite nucleation site in the ferritic microstructure. In our research we welded DSS specimen autogenously, with tungsten inert gas welding using pure argon and 94 % argon + 6 % nitrogen as shielding gasses. In the first case the sub-sequent solid-state reheating caused 20 % increase in the austenite fraction of the weld metal but with the use of mixed shielding gas only 5 % increase.

The Factors of Digitality and Sustainable Competitiveness in the Domestic Context
217-226Views:171The 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 Expectations and Motivation Regarding Future Income and graduation of the Students of the University of Debrecen, Faculty of Engineering
1-11Views:119My research conducted among undergraduate students of the Faculty of Engineering of the University of Debrecen examined the students’ incentive and income expectation broken down by their gender and by their ducation level. At the same time, it aimed to measure the impact factors influencing their motivation to get the degree and their ideas regarding the payment.

Analysis and Comparison of Forecast Methods for a Small Enterprise
14-21Views:348The application of forecasting models is an essential part of the profitable operations of every company. However, today’s small and medium sized enterprises (SMEs) does not pay enough attention to this field. This research presents a case study in which we tried to determine the sequence of a forecasting process, furthermore, determine the best applicable method to the dataset. Seven dissimilar forecasting method was applied: moving average and weighted moving averages with different periods (2-3-4 weeks), as well as exponential smoothing. The four-week-long weighted moving average served the best solution, which was tested by tracking signal as well.

Innovative Utilization Possibilities of Industrial Wastes from Hungary as Construction Industrial Material
203-212Views:110The research results carried out at the University of Miskolc Faculty of Earth Science and Engineering in the Center of Excellence of Sustainable Natural Resource Management show that the physical and mechanical properties of the construction industrial products (strength, compactness) made of waste sources can be controlled reasonably by the appropriate processing technologies and under optimized circumstances and characteristics (particle size distribution, specific surface area). It was established that beside the chemical activation, the mechanical activation of solids is an effective tool for improving the product characteristics. However, this modifies the physical as well as structural, mineralogical properties of the raw materials, therefore its determination is of great importance.
