الوصف: The subject of the work is electronic medical record linkage threat analysis and modeling with the use of the submitted data breaches list published by the U.S. Department of Health and Human Services. Multipronged data analysis with the use of statistics utilities and data visualization has been conducted. The model forecasting the number of data breaches based on a time series mathematical model has also been built. The article reviews the tools and techniques used in data security analysis and presents practical examples of modeling and analysis that can be used in practice to improve data protection. It was shown how important it is to protect personal data, especially medical data, and what tools can be used in the educational process of data analytics for students to effect data analysis, trend assessment, and data prediction.

الوصف: Present-day technologies used in SHM (Structural Health Monitoring) systems in many implementations are based on wireless sensor networks (WSN). In the context of the continuous development of these systems, the costs of the elements that form the monitoring system are decreasing. In this situation, the challenge is to select the optimal number of sensors and the network architecture, depending on the wireless system’s other parameters and requirements. It is a challenging task for WSN to provide scalability to cover a large area, fault tolerance, transmission reliability, and energy efficiency when no events are detected. In this article, fundamental issues concerning wireless communication in structural health monitoring systems (SHM) in the context of non-destructive testing sensors (NDT) were presented. Wireless technology developments in several crucial areas were also presented, and these include engineering facilities such as aviation and wind turbine systems as well as bridges and associated engineering facilities.

مصطلحات موضوعية: Multidisciplinary

الوصف: The theoretical and practical aspects and results of simulations based on a specialized tool that is used in the energy industry were adressed. The previously discussed cases in the literature by taking into account the worst case and critical states of networks in terms of complex networks were extended. Using the Monte-Carlo method, the vulnerability of the power grid to node failures was investigated, both in terms of the use of specialized software, which is used in the power industry, and a tool for the analysis of complex networks graphs. We present the results obtained and the observed analogy between the results of the analysis performed in specialized software and the complex network graph analysis tool. It has been shown that the results obtained coincide for both software packages, even though their application focuses on slightly different aspects of system operation. Moreover, further possibilities of extending the research in this direction are proposed, taking into account not only the improvement of the method used, but also a significant increase in the size of the tested structure model.

مصطلحات موضوعية: gamification in learning, playful experiences, smartphone applications, immersive learning

الوصف: The article analyses the impact of gamification on the effectiveness of the learning process with the use of the original mobile application. Gamification methods and gamification assessments attract more and more attention from both researchers and practitioners. We present the impact of learning rules and regulations of handball on the future referees of handball and people from the handball community (players, activists, sympathizers) from the implemented mobile application in comparison with the traditional method, i.e., from books or printed regulations. The results of the knowledge test for the users of the application were much better than traditional education. The analysis showed that in the first test, the users using the application and traditional learning achieved the same results (52%). In contrast, in the second test, the users using the application achieved 73% in comparison with the group not using the app (59%). Such a result may indicate that learning from the application has a good impact on the user. The adoption of gamification in learning and teaching is very popular and stimulating student motivation, involvement, and social influence.

الوصف: In this study, we focus on some problems related to virtual reality technology usage in supporting the educational process. The main goal is to obtain the optimal duration of exposure to virtual reality without the appearance of physiological problems for the user affected the achievement of teaching outcomes. Most of the characteristics of virtual reality software at the same time point out some issues in the areas of technological innovations, especially in the health context. The presented example of the VR environment’s training application shows the effectiveness of VR methods and their possibilities in training aircraft pilots. Teaching involving VR allowed to achieve, on average, as much as 90% correct answers, which in comparison with traditional methods resulted in an increase of 21 to 32.7% of correct answers in comparison with training using VR. The research confirmed that a critical challenge in the context of the broader use of VR in education is to appropriately adapt the learning materials and content to the technical requirements. Then, in certain areas, the use of VR is beneficial.

الوصف: The article presents results of studies using simulations on computer network devices, designed to examine the effectiveness of routing protocols with the video streaming and generated traffic for Jperf applications. In order to demonstrate the effectiveness of the selected protocols several simulation scenarios were made using different sized UDP packets. The traffic was analyzed in terms of statistical self-similarity. Multifractal analysis has also been made, using two kinds of spectrums. The study determined the relationship between them. These tasks were designed to determine the multifractal and long-term relationship for a given process.
