Title: Definition of Business Rules Using Business Vocabulary and Semantics
Abstract: This paper discusses the definition of business rules using business vocabulary and semantics. At the beginning business rules, business vocabulary and semantics of business rules are specified. There is also outlined the current state of research on this topic. Then the definition and formalization of business rules using semantics and business vocabulary is described. Based on these proposed procedures was created a tool that implements and simulate these processes. The main advantage of this tool is “Business Rules Layer”, which implements business rules into the system but is separated from this system. Source code of the rules and the system are not mixed together. Finally, the results are evaluated and future development is suggested.

Title: A Lightweight Anti-Phishing Technique for Mobile Phone
Abstract: Mobile phones have become an essential device for accessing the web. This is due to the advantages of portability, lower cost and ease. However, the adoption of mobile phones for online activities is now being challenged by myriads of cybercrimes. One of such crimes is phishing attack. In this work, a lightweight anti-phishing technique is proposed to combat phishing attacks on mobile devices. This is necessary because these mobile platforms have increased the attack surface for phishers while diminishing the effectiveness of existing countermeasures. The proposed approach uses a number of URL behavior to determine the status of a website based on frequency analysis of extracted phishing features from PhishTank. To increase the detection power of unknown pattern, a machine learning algorithm called Support Vector Machine is adopted. The results indicated that the approach is very efficient against phishing sites with negligible false negatives.

Title: HACS: A Hybrid Framework for Continuous Flexible and Controlled Architecting
Abstract: Systems like e-voting, e-banking or e-health must offer flexibility to continuously meet technical and legal changing requirements and must at the same time guarantee robustness to respect their security and sensitivity. Component Based Software Engineering (CBSE) and Service Oriented Software Engineering (SOSE) with their modular design represent the most suitable paradigms for those systems. They have strong complementary advantages, despite their similarities, their heterogeneity still hinders systems to benefit from both of them. In this paper, we propose a hybrid framework HACS (Hybrid Approach between Component and Service). HACS proposes to define sensitive systems as a hybrid architecture where the critical parts are controlled according to CBSE coupled to the flexibility and dynamism of SOSE. To address heterogeneity and make possible the substitution between hybrid components, HACS uses a common syntax with semantic annotations based on SAWSDL related to two ontologies; HACS ontology and domain ontology. We illustrate HACS all along the paper through an e-voting case study.

Title: Modelling the Effects of a Predictable Money Supply of Bitcoin
Abstract: The paper examines effects of a predefined and immutable money supply using a simulation performed in Minsky. It uses the cryptocurrency Bitcoin as an example and compares its settings and outcomes with Euro as a credit based fiat currency. Minsky is a specialized software for creating SFC economic models. It operates in continuous time. Unlike Euro, Bitcoin is a non-liability currency. It is not being issued against debt and it does not allow a fiduciary issue. The study examines the economy of the EU complexly, focusing on its monetary system, using Eurostat data. Then it changes the rules of the system so that they comply with the rules of Bitcoin’s protocol. The performed simulations show different effects of these monetary settings on wealth distribution among particular groups of economic subjects as well as on the stability of the economy as a whole after some time has passed.

Title: Influence of Non-Linearity on Selected Cryptographic Criteria of 8x8 S-Boxes
Abstract: The article defines standard criteria used to characterize the cryptographic quality of the S box: regularity, non linearity, autocorrelation, avalanche and immunity against differential cryptanalysis. The values of autocorrelation, avalanche and immunity against differential cryptanalysis for regular 8x8 S-boxes with non-linearity 98 and regular 8x8 S-boxes with non linearity 104 are compared. It is statistically verified that higher non-linearity improves the values of these criteria in a cryptographically advantageous sense.

Title: Analysis of the Survey Results About University Students Perception of Benefits of Supporting E-Learning Education
Abstract: The paper deals with the analysis of the answers to the results of the questionnaire survey on the e-learning system used at the Faculty of Business Economics of the University of Economics in Bratislava with seat in Košice, used at the Faculty in Košice and the workplace in Michalovce. The results of the survey point to the fact that respondents appreciate the use of e-learning form of education compared to its classical form (78 % of respondents) and the possibility of studying at any time (64 % of respondents). Part of the survey was focused on the analysis of the areas in which students have learned to improve their skills and knowledge on the basis of working with the e-learning system. Improvements were felt by respondents mainly in the field of the subject, communication area and informatics. As part of e-learning, respondents particularly saw room for improvement in expanding the e-learning portal content, for example, by lectures, more volumes, and by compilation of study materials requiring inclusion of other subjects into the system. Proper use of e-learning education will help to increase the quality and competitiveness of the provision of education more effectively, thereby increasing the satisfaction of students and meeting their commitments to society.

Title: The Emergence and Historical Development of Informatics and Computing Disciplines in Selected European Countries and the USA
Abstract: This article presents an overview that compares the historical tendencies in defining informatics as a new discipline, subject area or field of study focused on the design and application of computer technology. Apart from computer construction, the focus is on two major areas: computational processes and information processes. The article first considers the development in the United States of America (USA), which differed substantially from Europe. In the USA the development concerned disciplines referred to as computer science, computer engineering and (library and) information science. The article then discusses the situation in France and Germany. Consequently, the development in the USA and Western Europe is contrasted with the development in the Soviet Union, particularly with the crucial role of cybernetics in this region. The time range considered in the article is limited to the 1960s and 1970s. The article introduces the individual regional concepts of informatics and discusses the social, economic and political background of the emergence and development of these concepts. This view makes it possible to present an original approach to the ambiguous interpretation of “What is informatics as a scientific discipline in an international context”, while respecting the distinctions given by the outset and historical development in different countries.
