The impact of the ICT-supported instruction within the university education is the problem dealt in this paper. It is solved within the research running at the Faculty of Informatics and Management, University of Hradec Kralove, which focuses on comparison of study results which students reached in the traditional face-to-face lessons and in ICT-supported instruction in two subjects - Database Systems 2 and IT English. The sample group consists of approx. 350 students and final results prove no statistically significant difference between the approaches.

In recent years, information and communication technology (ICT) has been characterised by several evolving trends and new challanges. The design and management of each information system must address issues related to planning an ICT infrastructure. Communication technologies are evolving very fast, following the current trend of the time when everything is becoming digitized and the demand for new ubiquitous services is growing. This process has enabled the advent of the Next Generation Network (NGN). With the development of the Next Generation Network, considering the proposed infrastructure, speed, services and amount of connections will increase exponentially. At the same time vulnerability, threats, risk and quality of service (QoS), should be adequately assessed for the continuous evolution of the converged network, which will define roles and relationship in the future information and communication environment. In this paper we propose an overview of the Next Generation network addressing the new challenges of the converged infrastructure and we propose a framework to assess quality of service and security features, giving an appropriate analysis method regarding certain parameters and requirements.

In Telemedicine, confidential information is transferred through an unsecure channel from one party to another. In this paper, a field programmable gate array (FPGA) based approach to protect the data in the Telemedicine system, the mySECURE II is developed. There are two security schemes on a crypto System-on-Chip (SoC) proposed in this paper namely hybrid encryption scheme and Rivest-Shamir-Adleman (RSA) based digital signature scheme. It focuses on the development of 128-bit Advanced Encryption Standard (AES) subsystem, 2048-bit RSA crypto subsystem and Secure Hash Algorithm (SHA-1) crypto subsystem. In AES encryption and RSA crypto subsystems, the strength of these cryptosystems relies on keys. Therefore, a hybrid random number generator (RNG) is designed to provide on-chip key generation operation in this work. The crypto SOC is designed using hardware-software co-design technique. The hardware subsystems design are implemented on Altera Stratix 1S40F780C5 FPGA development board and integrated with Nios II processor to form a complete cryptosystem in System of Programmable Chip (SoPC) environment. The software design consists of the development of device drivers for hardware subsystem communication, and implementation of Cryptographic Service Provider (CSP), serves as the Application Programming Interface (API) in host PC. As a result, a prototype has been developed to test the functionality of the crypto hardware subsystem as well as the usability of the CSP.

Teaching and learning software engineering have been recognized as important challenges for computer science students and instructors. These challenges become stronger if we consider the distributed software development scenario that is gaining space everyday into the software industry. In order to help address this challenge, this article introduces a Collaborative and Distributed Learning Activity (CODILA). This collaborative activity helps students to reach the professional skills required in the professional work, and instructors to perform such transfer process. The paper also presents and discusses the obtained results from a particular CODILA, which address the challenge of designing a software architecture of a communication infrastructure in a distributed way. Six Latin American universities participated in the activity. The obtained results were satisfactory and indicate these types of experiences can be used to address the stated challenges.

As companies expand their businesses to the international marketplace, they will rely on their employees to have skills in using web-based information and communication technologies (ICTs) for collaboration. To simulate this global environment in the classroom, the authors created a six-week project in which first-year introductory technology students from Bentley University in the United States and fourth-year multimedia students from “Politehnica” University of Timisoara, Romania, used a number of ICTs during a semester project to evaluate two similar online collaboration tools. In doing so, they were able to develop several 21st Century Skills for Digital Literacy as identified by Jenkins. Students created blog posts, videos, and collaborative documents to chronicle their learning, shared their results within ViCaDiS, an online learning environment.

The explosive growth of recommender systems has resulted in realization of individualized service as commercial patterns and research prototypes. However, the traditional recommendation approaches are overemphasized the similarity between user preference and items feature. They are completely ignored affectivity that was a crucial factor. Our study focuses on exploring a new affective recommendation approach of semantic associated extension by integrating the Spreading Activation model with knowledge of cognitive psychology for the real-time preference-aware. This paper presents an affectivity-based recommendation approach to eliciting a characteristic sequence consisted of color nodes mapping the relationships between user preference with his mood and items feature. Predominance of our proposal was illustrated through an instantiation of movie recommender system that was developed based on the proposed approach. The testing results of performance show that our affectivity-based recommendation approach outperformed the traditional collaborative filtering approach in terms of the accuracy. This paper also presents a novel insight into exploitation of rich repository of domain-specific knowledge to provide real-time recommendation for user.

Current UK trend of empowering local communities and promotion of the “Big Society” concept are stimulating new research into practical ways of developing community participation. There is a need for a better understanding of the tipping points for this engagement and how ICT can make use of these. The aim of this research is to develop a frame of reference for effective community participation through ICT, applying both complexity and design perspectives to recognize the role of local interactions. Research will start by constructing a narrative of experiences to help develop semi-structured interviews. The successful outcome will be an effective and efficient, time saving framework.

This research aims to design an educational mobile game for home computer users to protect against phishing attacks. Phishing is an online identity theft which aims to steal sensitive information such as username, password and online banking details from victims. To prevent this, phishing education needs to be considered. Mobile games could facilitate to embed learning in a natural environment. The paper introduces a mobile game design based on a story which is simplifying and exaggerating real life. We use a theoretical model derived from Technology Threat Avoidance Theory (TTAT) to address the game design issues and game design principles were used as a set of guidelines for structuring and presenting information. The overall mobile game design was aimed to enhance avoidance motivation and behaviour of home computer users to protect against phishing threats. The prototype game design is presented on Google App Inventor Emulator. We believe by training home computer users to protect against phishing attacks, would be an aid to enable the cyberspace as a secure environment.

With the increasing popularity of Web services and Service-Oriented Architecture, we need sophisticated infrastructure to discover and compose Web services. Dynamic Web service Composition will gain wider acceptance only when users know that the solutions obtained are comprised of trustworthy services. In this paper, we extend our Web service Composition framework to include selection and ranking of services based on their reputation score. We present a technique to calculate a reputation score per service using centrality measure of Social Networks.
