Road Safety Management Model
Authors: Verica Danchevska, Zoran Joshevski, Dejan Danchevski

Abstract: Traffic accidents are a serious problem in every society. Traffic safety is a science that analyzes road accidents with material damage, lightly injured, severely injured and killed persons. This paper proposes that road safety investment can be optimised by the development of a road safety management model. Road safety strategies typically include a basket of engineering, enforcement and education/training measures but there does not appear to be any management model which permits the optimisation of road safety investment. The proposed model utilises linear programming to predict changes in road safety resulting from safety interventions. It is mainly based on research in the areas of engineering and enforcement since there is little published research on the correlation between education and accident reduction. The model output provides the accident reduction and associated costs resulting from feasible road safety strategies. This should benefit policy makers when allocating resources. This example will be good experience for Traffic safety management system in the Republic of Macedonia.

Entrepreneurship Skillset Build-up in the Conditions of the Fourth Industrial Revolution
Authors: Dimitar Kolev
In the conditions of fourth industrial revolution, it is very difficult to find new entrepreneurship ideas and windows. This paper delves into the modern ways to do entrepreneurship like digital, green, medical, educational, social, creative or art. Some creative and critical thinking techniques for entrepreneur windows are discussed and their implementation in education has been drawn. They include lateral thinking, the six thinking hats, simplify and their suggested usage for classes as role-playing games, puzzles and quizzes. A connection between leadership, entrepreneurship, innovation and creative thinking has been drawn. On that basis, a conclusion about usage of creative thinking techniques in educational centres to build up entrepreneurship and leadership skills has been done.

Digital Transformation of Postal Operators – Challenges and Perspectives
Authors: Anna Otsetova
The postal operators are facing unavoidable digital business transformation in the era of the digital economy, Industry 4.0 and innovations. The rise of digital technology over the last 30 years has created both threats and opportunities for the postal industry. Digital transformation of companies and correspondence is having an impact on the core business activity of postal operators. Nowadays, electronic communications impact all of postal operators businesses. The volumes of physical letters have been decreasing substantially, particularly in the last couple of years. Obviously, this leads to loss of revenue. At the same time digital innovations, e-commerce, data collection, and digital identity have been at the heart of postal operators’ efforts to propose new services, spawn efficiencies, and adapt their organizational culture and strategy to the needs of the digital economy. These tendencies require a different postal infrastructure as well as different skills and patterns of employment for postal operators. Hence, the digital transformation has become a strategic priority for postal operators. Although postal services play a vital role in connecting people, businesses and government across the world, the postal industry is grappling with its greatest challenge yet: digital disruption.
This article dealt with the opportunity and challenges faced by postal operators in age of digital transformation. It focusses on main drivers of digital transformation and the dimensions of digital transformation in postal services sector. Based on own study a penetration rate for postal e-services in Bulgaria is presented. The results show that extent to which postal operators in Bulgaria are offered e-services is far from fully exploited across the entire network. Based on the results digital strategy priorities of postal operators are proposed

Handoff in Various Mobile Network Technologies
Authors: Ekaterina Otsetova-Dudin
Mobile cellular networks are an indispensable part of modern life, where the need for customer satisfaction in the use of many different services by consumers is constantly increasing. The requirements for higher transmission speed, lossless transmission, reliability, efficiency, low latency, mass connectivity, guarantee of high Quality of Service criteria are repeatedly increasing. All this requires the continuous development of the used technologies as well as the introduction of new generations of networks. Handover mechanism is extremely important in cellular network because of the cellular architecture employed to maximize spectrum utilization. To ensure the quality of service in wireless cellular networks, the report proposes the use of a Horizontal Handoff Priority Scheme. Simulation experiments have been carried out, the probability parameters of the scheme have been evaluated and the probabilities of losses occurrence have been classified as rare events. The proposed material are various algorithms and techniques for the implementation of Vertical and Horizontal Handoff in 3G, 4G and fifth-generation networks to provide the required QoS for mobile users with Ultra-High Definition.

Organization value building on the basis of intellectual capital
Authors: Iwona Tomaszewska
A very important part of the theoretical analysis of intellectual capital is the analysis of the organization value building on the basis of intellectual capital. The innovativeness of the organization and its ability to absorb innovations can to  be a value of the organization. The investments in the intellectual capital during organization value building should lead to absorption of innovation. So the considerations connected to the organization value building on the basis of intellectual capital raised in this article might be of value for the future empirical work results.
