Az innováció fogalmának történeti áttekintése = Historical overview of the concept of innovation
Az innováció mindennapi része életünknek, még ha többségünk
nem is veszi ezt sokszor észre. Egy biztos: az idők kezdete
óta folyamatosan jelen van az emberiség történelmében. Ennek
következtében számos tudóst késztetett arra, hogy külön
vizsgálat alá vonja az emberi, technikai újítás, megújulás
képességét, lehetőségeit. A dolgozat az innovációnak, mint
társadalmi-közgazdasági-technikai fogalomnak a történeti
áttekintését igyekszik bemutatni, az egyes tudosók vélekedése

Innovation and organizational culture - change management issues in a financial institution's organizational culture
Az ökológiai innováció helyzete és jövője Magyarországon = The eco-innovation in Hungary – present and future
The innovative EU – the future of Europe
In this study, I am going to compare the current innovation performance of the European Union
with that of its competitors and give guidance on how to promote the flow of knowledge in
Europ
e thereby enhancing the efficiency of the R&D sector. These processes might be solutions
to recover from the economic crisis and make progress in the 21st century
The Hungarian Innovational Potential and the R&D Sector
Usually, when one says „innovation”, novelty and the ability to
renew come to mind. The measurement of the concept has become a
very important field of study and a key indicator of national
economies. In this article, after a short review of the
theoretical approaches to innovation, I am going to examine the
status of the Hungarian R&D sector. Where is Hungary now in
terms of innovational activities? Who are the actors and the
funders of the system, and more importantly: in what proportion?
What fields are prominent in domestic practice? Amongst others,
I set out to find the answers to these questions in this
article.

Analysis of Vibration During Turning Process of Different Materials
In this article, we would like to introduce the problems caused by vibrations in case of polymer turning processes. Nowadays there is a lot of research in this topic, to avoid the unnecessary phenomena of vibrations. The two most common methods are the Spindle Speed Variation (SSV), and the Vibration Assisted Machining (VAM). In case of SSV, the CNC machine can increase and decrease the speed of spindle continuously during turning which can significantly reduce the effects of chatter. This method is beneficial for longer workpieces when there is not any support except the chuck. Vibration-assisted machining can be used to minimise the problems caused by vibrations. VAM combines precision machining with small-amplitude tool vibration to improve the fabrication process. It has been applied to some processes ranging from turning, drilling to grinding. Based on the enumerated above we made some trial measurements about the basic vibrations of the turning tool shank. The tests were done on an NCT EUROturn-12B CNC machine which can found in the workshop of our institute. The tested material was Polyamide 6 because this is the most commonly used polymer in the industry. In the future, we would like to test some other basic and composite polymer materials too. The equipment was served by a specialist from SPM Budapest Kft. With these tests, our goal was to make sure that the equipment and the measuring setup are suitable for our future research
