Analysis of the performance of various communication networks is often realized by researchers using simulation tools which can be free or commercially oriented. Network simulator (v.2) is a free, powerful and worldwide used simulation tool but it is not equipped by a graphical interface and therefore users have to spend additional time to gain an ability to work with it. This considerably restricts its usage in educational processes. In this paper we provide detailed comparison of third party tools developed to enhance and simplify work with Network simulator and we also mention reasons why we developed our tool with name GUIns2 which provides not only a graphical interface for Network simulator but also supports other simulation based activities. GUIns2 is characterized with a focus on an every phase of the simulation process. To better understand our tool and its contribution we proposed and described one wired network simulation scenario. GUIns2 makes simulation capabilities of Network simulator more accessible to wider base of users.

In today's fast-paced world access to the right information for the right person at the right time is critical, and it is not necessarily related to business life. The same applies to students using e-learning systems and contents. As there are seemingly never-ending news reporting different types of security vulnerabilities and exploits on a daily basis, security and privacy have become top priorities. People are forced to share confident and sensitive information through different services on the internet, while relying on the security they offer can be misleading at best. Even if strong and complex passwords are required from the users, there is no guarantee that even the underlying protocol or services do not contain any security vulnerabilities. So it is extremely important to realize that other factors must be involved during the authentication process without making it too complicated for the everyday use. In this paper the more and more popular two-factor authentication method is proposed as a reasonable and promising solution, and an example is also given how it can be implemented for e-learning systems currently available.

In this paper are presented the approaches and measures taken in order to enhance the learning process of computer networks. During research described in this paper we take into the consideration primarily traditional form of education, i.e. active presence of student at the institution. Enhancement itself lies in the elimination of system testing and its replacement with testing on the real devices. Overall experience brings promising results and improvement in the educational process.

Discrete Fourier Transform (DFT) is a well-known mathematical tool used for scientific and engineering purposes. One of the areas, where DFT is frequently used is digital signal processing (DSP). The application of DSP techniques is used in many diverse areas, from telecommunication sector through medical data processing up to modern home entertainment systems. Many of the DSP applications require real time data processing. In the scientific area the DFT is frequently used for modelling of electrical circuits, communication systems and other areas, where the direct (from time domain to frequency domain) and inverse transformations are performed. This contribution presents two available libraries to accelerate DFT using parallelization. Presented libraries are implemented for use on recent computer processors (Central Processing Unit, CPU), as well as for the calculation of the graphics cards (Graphic Processing Unit, GPU). We briefly introduce the libraries and then present the comparison of their performance.

The aim of the study was to demonstrate whether and how information technology affects human development, particularly in the shaping of creative attitudes. Creative attitudes were examined by standardized questionnaire of KANH creative attitudes. The study aimed to demonstrate how Biofeedback training method affects the level of creative attitudes. In the group with predominance of reproductive attitudes, after training there was an increase of creative attitudes, some people slightly decreased level of creative attitudes. The important news is that there has been a decline in reproductive activities. In the group of patients with a predominance of creative activities, in certain individuals, there was an increase in creative behavior. In more than a dozen people was minimal decline of creative attitudes. There was a decline of reproductive behavior in a few subjects, while in a few, this attitude remained unchanged. The paper pointed out that in most subjects, under the influence of biofeedback training method there has been a decline in reproductive behavior. Only in one of the individuals, reconstructive operations have not changed. It is noteworthy that decreased reproductive attitudes even among those who interrupted therapy.

The paper focuses on the field of the possible use of mobile devices for education. data were collected by the questionnaire method from 203 respondents - FIM students monitoring the ownership and use of the devices for personal and education purposes. The results show the mobile devices are widely spread among the FIM students so their systematic implementation into the process of instruction cab start.

Many years have in education dominated theoretical information and knowledge transmission and relatively little (or no) attention has been paid in practical experiences, creativity and innovation. However, in current dynamically changing and by information and technologies supersaturated environment becomes creativity an important determinant of the success of organizations because of its ability to generate new/innovative ideas, products, and solutions. Educational institutions are facing a new challenge - to prepare students - the future workforce - so that they are able to adequately or creatively address the problems and challenges, think critically and unconventionally (out of the box), act quickly and efficiently. The paper summarizes existing business simulation literature and provides some authors' experiences and outputs of the research on students' attitudes to the use of business simulation in education as a “innovative” teaching method.

According to current researches, individual differences in eye movement patterns may be related to different ways of text processing, to comprehension difficulties, etc. They also depend on the nature of the text. Particular question is how reading takes place in case of using figurative (visual) language, e.g. in case of metaphors, irony, or fixed phrases (phraseologisms). Based on other researches, it is evident that the development level of executive functions of each individual is strongly tied to their sociocultural background, especially to the parenting style of their family; on the other hand, differences in executive function significantly affect a person's performance at school. The notable part for the aim of this paper, however, is the direct link between executive functions and eye movement, i.e. on the basis of eye tracking it is possible to make direct, unaltered conclusions on executive functions [1]. Electronic screens on laptop and tablet computers and smartphones are being used for reading text, often while multitasking [14]. The question arises whether reading from a screen is as effective as the reading from textbooks. One of the aims of the paper is to verify the visual patterns of information retrieval from screen for problem comprehension and solving using eyetracking technology.
