Opis:
Let us assume that some businessmen wish to have a meeting. For this to happen, they usually have to meet somewhere. If they cannot meet physically, then they can take part in a video (or audio) conference to discuss whatever needs to be discussed. But what if their meeting is meant to be private? In this case they need a cryptographic protocol that allows them to exchange their ideas remotely, while keeping them secure from any potential eavesdropper. In this paper we list all the necessary requirements that a cryptographic protocol must have in order to allow several businessmen to exchange their ideas securely over the Internet. Moreover, and based on the standard taxonomy of cryptographic protocols, we suggest several approaches on how to design cryptographic protocols that enable us to achieve our aim. Finally, we propose the design of a protocol that solves the meeting businessmen problem.

Opis:
The presented paper describes the characteristics of a study conducted on Synchronous Virtual Classrooms (SVCs), virtual spaces which harbour such resources as videoconferences, shared desk-tops, etc. The main objective of the research was to assess teaching and methodological, communication and technological aspects of SVCs in e-learning processes. Empirical methodology of quantitative and descriptive nature was used; a questionnaire was designed to assess these issues with a sample of 116 university students from six different fields of study at the University of Extremadura. As a conclusion, we report that SVCs with a constructive methodology enhance students’ creativity, favour virtual collaborative work, promote critical and independent thought, and create alternative channels to stimulate students’ active participation by means of flexible and attractive interfaces.

Opis:
The article aims to analyze innovative solutions in the areas of virtualization and video communication within economic and social processes. Some general trends in computer-mediated communication have been identified. Our findings that confirm these trends relate to telework and new challenges in supporting religious practices. We see trends emerging that create entirely new opportunities to boost the efficiency of decision making and management processes in organizations and to support all kinds of social processes.

Opis:
This paper is a report in brief of the project that “Henri Coanda” Air Force Academy, in collaboration with partners from Poland and Bulgaria, carried out under the aegis of the Erasmus + program of the European Union by the end of 2018. The project was called Systems for Aerial Surveillance and Security (SASS). The project proposed the initiation of a process of uniformisation of competences necessary for the people involved in the field of aviation, namely obtaining a joint study plan for pilots, air traffic controllers, and air surveillance officers [3]. It opened the way for cooperation between the Air Force Academies that began a joint semester of study. Achieving the objectives of the project meant introducing an online teaching/learning system based on an e-learning platform. The e-learning features have been fully utilised through the introduction of a videoconference system that allows teaching/learning activities for professors/students at a distance. The completion of the project was carried out by evaluating the results obtained at different stages. The analysis was based on the feedback from the main target groups - students, teachers and beneficiaries of the graduates. Two periods of teacher and student mobility were required for evaluation and analysis. The students’ and teachers' opinions on the implementation of the curriculum by means of the e-learning platform were analysed in detail.
