European Journal of Business Science and Technology 2017, 3(2):81-89 | DOI: 10.11118/ejobsat.v3i2.105 
Recent studies have underlined a limited scope of research published with regard to the impact of cybercrimes, which is investigated by applying the scientific literature analysis and surveys. This paper focuses on in-depth research on cybercrime costs by analysing the information from selected online materials in order to reveal a research gap. To support the contributions of the research in the field, two methods, namely, literature review and statistical analysis were employed. The findings reveal that several interested parties such as independent IT companies, governmental and non-governmental institutions have conducted various surveys to identify...

Vietnam, is one of the developing countries, which approaches new technology, especially Internet is extremely fast approximately 67.1% in the population in 2017. With the boosting of information technology, it creates a new environment and tool to reach the customers' requirement. The new and effective method of narrowing the gap between the distributors and clients is electronic commerce (e-commerce). E-commerce is one of the most innovative expansions of the technologies that enable small and medium-sized enterprise (SMEs) access to global communication and trade. It can help SMEs expand their businesses to global market and increase sales, reduce...
Overview of Web Anonymization
Tomá¹ Sochor, Cyril Klime¹
European Journal of Business Science and Technology 2017, 3(2):96-105 | DOI: 10.11118/ejobsat.v3i2.101
Web anonymization tools have been used for a long time, primarily by the users afraid of possible undesirable consequences of their on-line activity on the web. The paper analyzes both historically proven anonymization tools like TOR and newer tools, namely JAP/JonDo and CyberGhost VPN that are based on slightly modified technological principles. The primary focus is given to the measurement and evaluation of the latency increase and the transmission speed decrease in comparison to normal (non-anonymized) web browser operation. Results show that all anonymization tools being subject of the analysis provide relatively moderate latency increase. On the...
Source Code Plagiarism Detection for PHP Language
Richard V¹ianský, Dita Dlabolová, Tomá¹ Foltýnek
European Journal of Business Science and Technology 2017, 3(2):106-117 | DOI: 10.11118/ejobsat.v3i2.100
This paper introduces a system for detection of plagiarism in source codes written in the PHP computer language, part of the plagiarism detection tool Anton. We used the greedy string tiling algorithm together with tokenization and hash calculation. The efficiency of the system was tested on both an artificial dataset and on real data coming from a course taught at our university. Our results are compared with other similar systems and solutions, concluding that Anton can detect all examined types of plagiarism with higher accuracy than other systems.
System Modelling and Decision Making System Based on Fuzzy Expert System
Radim Farana, Ivo Formánek, Cyril Klime¹, Bogdan Walek
European Journal of Business Science and Technology 2017, 3(2):118-122 | DOI: 10.11118/ejobsat.v3i2.103
They are available many modeling and decision making systems. Some of them are based on statistical methods like time series analysis. The general problem of these systems is that they cannot correctly react to the changes of modeled systems and their environment. This paper presents an approach based on the fuzzy expert system application, which is able to represent the expert knowledge about the modeled system behavior. This approach combines the statistical methods with expert knowledge and is able to give appropriate information about the system behavior and help with the decision making process. The presented paper describes general principles...
Decision Making on Various Approaches to Importance-Performance Analysis (IPA)
Jolanta Wyród-Wróbel, Grzegorz Biesok
European Journal of Business Science and Technology 2017, 3(2):123-131 | DOI: 10.11118/ejobsat.v3i2.82
The purpose of this paper is to compare several approaches to Importance-Performance Analysis (IPA) and show how different criteria can be used for dividing the IPA matrix to decisionmaking fields. The authors performed the IPA analysis basing on the data collected in customer satisfaction survey in health care sector. The survey was conducted from January to April 2016 in selected dentist's surgeries in cities ¯ywiec and Bielsko-Bia³a (southern Poland). Over 200 questionnaires were distributed, 100 of them returned. The study may facilitate the selection of appropriate form of matrix used in customer satisfaction surveys. It may be useful in future...
Affects Corporate Taxation Economic Growth? – Dynamic Approach for OECD Countries
Veronika Nálepová
European Journal of Business Science and Technology 2017, 3(2):132-147 | DOI: 10.11118/ejobsat.v3i2.104
This contribution deals with issues of corporate taxation in relation with economic growth. Its main objective is to quantify and analyse the relation of corporate taxation and economic growth using of OECD countries. The corporate tax rate is approximated by effective corporate tax rates such as corporate tax quota, marginal effective and average tax rates as determined by micro-forward looking approach and the alternative approach World Tax Index. The relation of taxation and economic growth is verified using an econometric model based on panel regression methods and tests using a dynamic panel. The model has shown a negative impact on economic growth...
