Aim of this research to analysing the level of the information security awareness of the undergraduate economic information technology students after the information security course. The young generation use smartphones, tablets to keep in contact with friends at home, on public transport, in the school etc. They use different communication forms on the internet like social networks, chat rooms and so on. These applications are protected by password authentication system to keep save the data of the users. We were interested for which systems find the Economic information technology students important in everyday life and what kind of password use for protecting the information. We see almost in every month in the news a service provider was attacked again by hackers and the have put the username and the passwords on the Internet. The success of the attack depends on user error mainly. On the one hand this research is important to see how complicated passwords use the students after the information security course and on the other hand how they will protect the important information at the work. The students filled out an information security awareness questionnaire after the information security course. The students had to say, which communication systems are more important, how long password they are using by the most important systems like e-mail, community sites, and so on, how complicated is the used password, how often change the students these passwords. Are they using same passwords by different systems or one same password? After the analysis could we see how effective was the information security course for the economic information technology students. How could we build the information security awareness by them to help them to keep save the sensitive data? © 2016 IEEE.

Looking back to the last 10 years of SPI, we can see a rapid change of focus from models to people. Models like CMMI, SPICE, Information Technology Infrastructure Library (ITIL) or others still will remain useful. However, they do not have the power to create competitive advantage. What we see in all analysed approaches is that people really count. That competitive advantage has one important source in the commitment and the responsibility of people for their processes in terms of effectiveness, efficiency and results quality. And it has also a source in the people's attitude to reasonable changes. Even if the approaches of Hammer, Jacobson, the ImprovAbility Model, the SPI manifesto, the ECQA Scheme and the SPI manager qualification scheme seem to be different on the first view, they all agree on the relevance of people and their needs. © 2011 John Wiley & Sons, Ltd.

Multiband aerial mapping technology—for the high spectral and high spatial resolution images—also the phenomenal traditional aerial mapping techniques, which are more reliable, compared to data obtained during the foundation stages of the process. Over the last decade, aircraft data recording technology has developed considerably due to its applications in the field of research and has become an increasingly central theme of multiband and high spatial resolution integrated processing. This has a significant impact on assessment results. Using practical examples, the author’s show that a properly selected spectral fractal structure based on data reduction and data selection procedures, significantly contributes to the hyper-and multispectral data cube optimum exploitation of additional information. © Springer International Publishing Switzerland 2015

Two decades ago it was made the first steps to establish a really Hamiltonian description of field theory of dissipative transport processes in order to apply all of the tools of modern field theories for these kind of processes. The great breakthrough was to introduce such scalar potential fields for the measurable quantities-temperature, pressure, etc.-, by which the complete Lagrangian-Hamiltonian formalism could be developed. Later it has been managed to create the differential equation for the relativistic invariant heat propagation by the help of the scalar field, which field can generate a dynamical temperature immediately. In the present paper it is focused on a farther step in the Lorentz invariant thermal energy propagation. Now, the temperature field satisfies a covariant field equation of a (wave-like) thermal energy propagation with finite speed-less than the speed of light. In our previous works the connection has been clarified between this scalar field and the usual local equilibrium temperature including the classical Fourier's heat conduction. The existence of a dynamical phase transition between the two kinds of propagation, between a wave and a non-wave, i.e., a dynamical phase transition between a non-dissipative and a dissipative thermal process is also found. Presently, it is pointed out that the so-called Wheeler propagator can be obtained without any difficulty for this process inspite of the existence of the dynamical phase transition and it can be seen that the causality condition is completed at the same time. © 2010 Springer Science+Business Media, LLC.

Nowadays, it is in the main stream of the recent researches that on nanoscale the sample size has an essential contribution to the behavior of the transport processes. In the present paper it is pointed out how to take into account not only the size parameter but the boundary contributions (wall effects from the reflections and scatterings of the phonons). The mathematical calculations are based on the fluctuation dissipation theory for the thermal transport. Calculating the spectra and the related time correlation functions the dynamics of thermal signal propagations are studied via the change of the behavior of the correlation functions in thin (60 and 100 nm) silicon layers. It can be easily recognized from the results of the elaborated calculations how the radical change appears in the signal propagation due to the contribution of the boundary effects. Finally, detailed examples are calculated numerically and analyzed graphically to show how the dynamics of the heat propagation changes depending on the wall effects at nanoscale. © 2012 Elsevier Ltd.

The application and introduction of ERP systems have become a central issue for management and operation of enterprises. The competition on market enforces the improvement and optimization of business processes at enterprises to increase their efficiency, effectiveness, and to manage better the resources outside of the company. The primary task of ERP systems is to achieve the before-mentioned objectives. For this reason the selection of a particular ERP system has a decisive effect on the future operation and profitability of the enterprise, i.e. the selection phase is highly relevant step within the introduction and implementation stage of an ERP system. The issues that are worth investigating are the criteria applied at the decision. The qualitative correlation between the size of enterprises, market position, etc. and the applied selection criteria for ERP systems could be analyzed as to whether which criteria are made use of at multinational enterprises or at SMEs. Our research is grounded in a literature review and case studies of everyday practice related to introduction, implementation and roll-out of ERP systems and it tries to provide answers for the above raised questions.

The competition on the market enforces companies to adapt to the changing environment. Most recently, economic and financial crisis accelerates the alteration of both business and IT models of enterprises. The forces of globalization and internationalization motivate the restructuring the business processes then consequently IT processes. To depict the changes in a unified framework, we need the concept of enterprise architecture as a theoretical approach that deals with the various tiers, aspects and views of business processes and different layers of application, software and hardware systems. The research carried out up to now unraveled the typical structural changes, the models for internal business networking and their modification reflects the centralization, decentralization and hybrid approaches. Based on the results achieved recently by investigation future research program are drawn up to deepen our understanding the trends within the world of ERP systems.

In the past years, efforts in the field of Software Process Improvement were increasingly focusing on human aspects realizing that people participating in the processes have a high impact on the success of any improvement. While these aspects are included in newer models and methodologies, it is still vague how Software Process Improvement can be made suitable for different people. In this paper, we propose a new approach: the application of usability methodology for Software Process Improvement. We present an overview of the people aspects in Software Process Improvement and introduce a methodology to apply usability methodology in this context. We also formulate ideas on how to adapt concrete improvement methods based on the usability methodology. © Springer-Verlag Berlin Heidelberg 2011.

The aim of this paper is to examine the European Monetary System (EMS) and its Exchange Rate Mechanism (ERM) regarded as the forerunner to European Monetary Union (EMU). It may contribute to understanding the nature and the operation of the monetary integration of the single currency area. The paper examines the reasons why the European Monetary System was formed in 1979, whether its crisis could have been avoided in the early 1990s and how the "new" ERM worked out. The ERM was succeeded by ERM 2 from 1999 in which the euro became the anchor for the other participating currencies. The global economic and financial crisis has brought both the structural and the operational weaknesses of EMU to the surface. The future of the European monetary integration is vital for Europe. The euro crisis is often perceived to have been caused by the global crisis. The ERM did not seem to have laid the groundwork for the monetary union and the Maastricht Treaty also has some critical points determining the operation of EMU in the long run. It is essential to gauge the euro-zone from the aspect of its vulnerability and susceptibility to crises to prevent a recurrence.
