    • Guidelines for the application of artificial intelligence in the study of the influence of climate change on transport infrastructure

      pg(s) 75-78

      We are witnessing the massive and impressive penetration of artificial intelligence (AI) into many areas of human activity. This process is expected to intensify in the next few decades. In most technical fields, there will be a preponderance of the so-called narrow artificial intelligence with clearly defined tasks and functions. It is usually a coherent set of neural networks trained to solve specific problems. The advantage of narrow AI is that it is entirely controllable and, at the same time, has excellent capabilities. This publication aims to outline guidelines for applying narrow artificial intelligence in investigating the impact of climate change on transport infrastructure. After a brief introduction to narrow artificial intelligence and climate change, various possible areas suitable for AI modeling are explored. Directions and preparatory tasks for collecting climate-sensitive local data on the condition and changes in the transport infrastructure in Bulgaria necessary for AI training are identified.

The difficulties in achieving this goal come from the fact that it is influenced by many and different factors. With this report, we aim to specify the global goal of industrial development and its particularities. The need for hybrid specialists and activities, their essence and their saturation with novelties. Duration and their importance in the stages of industrial revolutions. A proposal is made to specify the resources by grouping them into two groups, material and human, and to propose approaches and ways for their effective use. Special attention is paid to the preparation and qualification of hybrid specialists to implement this process.


    • Security related BPMN-extensions for RPA

      pg(s) 81-82

      Direct Robotic process automation (RPA) has received a lot of attention because of the increasing demand for solutions to improve the efficiency of business processes in an organization. With RPA, organizations can develop robots that automate a large number of processes. However, despite its relevance, RPA is a relatively young field and many of its concepts remain open to discussion. One of the primary tasks in creating a robot is the identification of threats at the design stage, which reduces the number of possible attacks, identifying vulnerabilities, thereby increasing the security of the robot itself. The increasing use of RPA-based solutions in mission-critical systems has created a need and interest in assessing their threats. The foundation for successful creation, launch and use of a secure RPA-based solution would be application of classical design techniques and evaluating the risks on all SDLC cycle stages. But in order to perform this appropriate tools taking into consideration the specific nuances of the domain area are needed. BPMN notation, used for describing business processes can be seen as a good candidate for designing RPA solutions. However, BPMN is not able to cover the description of all aspects in the robot process, namely, issues related to the specifics of RPA security remain unaccounted for. This study analyses business process notation (BPMN) as a modelling tool for the design of automated processes in RPA, proposes an approach for defining securityrelated extensions of BPMN using its own extension mechanism, that can be used for risk analysis on different SDLC stages.

    • Virtual workplace: current knowledge, changes and a new perspective on the way of work. A Systematic Literature Review

      pg(s) 83-88

      Today’s world is full of rapid changes, accompanied by an unsustainable pace of technological development. Thanks to the advent of virtualization, the way of working is changing as the dependence on time and space ceases to influence work opportunities. Globalization, information, and communication technologies mean that we are encountering more and more concepts such as virtual teams, virtual leadership, or remote working in companies. At the same time, virtualization, accelerated by the COVID-19 pandemic, opens up a range of new issues that require greater interest from researchers – such as the specifics of women working from home, the gender gap, ways of coping with stress, and others. Our paper is therefore dedicated to a systematic review of the literature on virtualization. Based on a qualitative analysis of the 30 most cited works from the Web of Science database that relate to the topic of the virtual workplace and were published in 2018-2022, we provide an overview of the current issues and challenges facing the corporate sector today. The VOSviewer and Voyant Tools software were used for the systematic literature review. Our research provides an overview of the most important topics related to virtualization while presenting problems and existing research gaps.

    • Preventing potential hazards in the development of machinery

      pg(s) 89-92

      The article focuses on the definition of industrial business risks that are associated with risk management. Following the description of the risks, the article then focuses on the elimination of the hazard or the reduction of each of the two criteria that determine the risk in question, such as the severity of the damage caused by the hazard and the likelihood that the damage will occur, separately or simultaneously, are two ways to achieve the purpose of risk reduction. The article is highly relevant to the implementation and development of technical systems and equipment.


    • Metaverse in Education

      pg(s) 93-94

      The presence of technology in everyday life has also entered the field of education, including as a virtual environment. Metaverse is one of the technologies that can bring new learning and teaching processes. It is a virtual environment that allows multiple users to interact in a 3D space. This technology can bring new ways of learning and teaching, such as simulations, virtual visits to museums or historical sites, virtual exercises, and more. The use and development of applications for these technologies, as well as artificial intelligence, is the connection between ICT and educational techniques. The goal of this article is to define metaverse and describe the roles of virtual, augmented, and mixed reality. The use of artificial intelligence and applications in metaverse can also bring new opportunities for personalized learning that adapts to the needs and preferences of individual students. For example, based on the analysis of the data from previous interactions and results there can be created recommendations for students and their learning.

    • An Interactive PLC Programming Application on Unloading and Handling Systems with Undergraduate Engineering Students

      pg(s) 95-98

      This article describes an experimental setup for the practical teaching of process control in an undergraduate mechanical engineering curriculum. The system is practice-oriented and is based on developing students’ skills in control system application of real process systems. A PLC (Programming Logic Controllers) program is proposed to introduce simulation aspects and final control design practices in scale processes (Unloading and Handling Station). It is based on the principle of introducing a PLC-supported, Siemens Simatic S7-200 PLC controller-controlled production system with the help of SIMATIC Step 7 Programming Software, presenting the scenario for the system and writing the PLC program accordingly. This algorithm prepared for the Unloading and Handling Station operation is not unique and without alternatives. The aim here is to enable students to get to know the system and program the system with different approaches according to the algorithm they have developed.

    • Evaluation of the learning success in the implementation phase of Extended Reality

      pg(s) 99-104

      Extended Reality (XR) stands as a hypernym for Augmented Reality (AR), Mixed Reality (MR) and Virtual Reality (VR) technologies and represents an increasingly important Industry 4.0 technology rank. XR technologies are enriching or replacing the environment with digital information. This introduces new possibilities for learning, collaboration, product presentation or other fields of application in companies. Various meta- and individual studies prove a positive influence of XR elements on learning success. However, the appraisal of results must be made with caution since no standard is currently available to measure learning success. This paper contributes to this situation by providing a framework to perform a generic measurement of learning success when using XR. The developed framework follows the 4-level evaluation model according to Kirckpatrick focussing on response, learn, apply, and benefit to the organization and is further developed meeting the specific requirements of XR training. The developed framework adresses two dimensions: the evaluation of the short term as well as the long-term training success. Furthermore, the paper gives insights in the practical validation of the framework done by an industrial company using a VR Training within the onboarding process. The framework is intended to help organizations to systematically assess the learning success of XR-supported training compared to traditional paper-based training.

    • Evaluation of the screen time children spend daily for using digital technology

      pg(s) 105-107

      The survey “Evaluation of the screen time our children spend daily for using digital technology” was conducted as part of a master thesis in Social Entrepreneurship at the American University in Bulgaria in March 2023. Analysis of the data for “time spent” by children on interacting with electronic devices is increasing alongside with the grow of the child and is directly influenced by entering formal education system. Acceptable “time spent” for the majority of parents is 1-2 hours in age group 5 to 9 (pre- and primary school) and 3-5 hours for 10 and above (when children enter the phase of adolescence). The parental that digital technologies are having positive
      impact over children (educational, social and digital skills development) is growing with the child growing up, and for the age group 10 -14 (secondary school) and 14 and above (gymnasium) it is dominating among parents.
