Innovation and investment mechanism for the formation and implementation of state policy to ensure the technological competitiveness of leading countries and Ukraine in the digital economy

The aim of the study is to assess the technological competitiveness of the leading countries and Ukraine as well as the formation of an innovation and investment mechanism to improve it. The article presents the scheme of research of technological competitiveness of the leading countries and Ukraine on the basis of qualitative and economic-statistical analysis, analysis of comparative advantages, grouping method and correlation-regression analysis. Analysis of foreign trade in high-tech products showed that the studied countries occupy more than half of this market. The studied countries take an active part in international economic relations since they have rather high export quotas but the ratio of the export of high-tech goods to GDP is very low. The analysis of comparative advantages showed that Ukraine has the greatest preference for the export of aerospace products, Germany for pharmaceuticals, China for office equipment, the United States for instrument making, and only China for telecommunications. It was determined that France, China, and South Korea have the highest level of innovation in national exports, and Ukraine and the Russian Federation have the lowest.

Economic and legal aspects of the use of computer programs

Keywords: computer program, economic and legal regulation, taxation, licenseagreement, initial cost, value added tax, royalties The article deals with the economic and legal aspects of using computer programs inbusiness operations. In particular, certain problems of taxation relating to the creationand use of computer programs are considered. There have been consideredways and means of representations in the accounting of the following operations: purchaseof intellectual property rights to a computer program, supply of a computer programfrom a non-resident (resident) to a resident. The principles of the formation ofthe cost of a computer program, depending on the terms of purchase, have been outlined.The has been defined the concept of royalties from the use of a computer programin the economic activity of an enterprise. The article indicates that the supply ofservices (performance of work) related to software products and that introducechanges to the software are deemed to be any updates, changes, additions to expandtheir functionality. Such an operation is referred to as the supply of software productsusing IT benefits. The supply of services that do not introduce changes, namely: installation,configuration, testing, identification and rectification of deficiencies, information,and consulting support is referred to operations that are subject to VAT atthe general rate. The article states that VAT is charged on operations for the supplyof software products from a non-resident (resident) to a resident in the customs territory(customs territory) of Ukraine, which, in turn, is not subject to VAT. At the sametime, if as a result of the provision of technical support services for software products(including software products provided for use under the license agreement) there areno changes in software products (for example, training staff to work with the program,installing the program, configuration of office equipment, etc.), then operationsfor the provision of such services are subject to VAT in the generally established mannerin the amount of 20 percent.There has been determined the need to improve economic and legal regulation ofthe creation and use of computer programs in the economic activities of companies interms of taxation.

A METHODOLOGICAL FRAMEWORK FOR RESEARCH OF ERGONOMIC RISK FACTORS IN DENTISTRY

This paper proposes a methodological framework for the research of ergonomic risk factors in dentistry, since this is a profession with very specific and complex ergonomic challenges. When analyzing ergonomic risk factors in dental practice, three separate entities should be taken into account: the dentist, as the central figure in the office; the dental office equipment, which includes all the instruments and devices, dental chair and dentist stool; and the dental office, including the workplace layout and the working conditions. Bearing in mind that it is impossible to eliminate the risk, systematic analysis of ergonomic risk factors enabled us to propose solutions for its reduction. Risk reduction improves dentists’ work ability and working conditions in the dental office and contributes to a more humane, i.e., more functional design of dental equipment.

Justification of technical solutions for facades of reconstructed industrial buildings in terms of energy saving and safety

Introduction. Reconstruction measures can restore production assets of an enterprise, ensure its economic efficiency, solve transportation and environmental problems. A relevant objective is to identify a set of the most important tasks of reconstruction of an industrial facility. Development of draft design proposals for the reconstruction of industrial buildings is complicated by the fact that a designer has to make a compositional link between “old” and “new” architecture, different in style and functionality, while focusing on the use of the most advanced effective materials and modern industrial structures. The article describes features of technical solutions for facades in the course of the reconstruction of industrial buildings aimed at the improvement of their energy efficiency and safety. Materials and methods. Reconstruction of industrial enterprises performs the function of transformation of industrial areas. Modern industrial architecture is focused on industrial tasks, such as the workplace protection from negative environmental effects (wind, rain, cold); arrangement of effective lighting in the workplaces; rational arrangement of workplaces, office equipment and production lines, auxiliary and service facilities, etc. Results. If there are social, historical, and architectural reasons to preserve a building, it is necessary to reconstruct and improve old industrial buildings and change their technical and economic characteristics. The reconstruction of a building means its modification aimed at changing its functionality in part or in full, taking into account the future prospects of the building. Conclusions. When restoring wornout elements of buildings that have historical significance, new elements are made in such a way that the appearance of a building remains unchanged or looks identical to its original historical appearance. Most industrial buildings, built before the law on energy performance of buildings was enacted, do not meet current regulatory requirements in terms of the thermal protection of the building enclosur.

Labor safety of medical personnel in medical organizations of stationary type

The aim of the research is to study the safety system of nursing personnel in medical institutions of the stationary type. Results. The most important conditions forthe effectivework of nursing personnel are: medical care of personnel, the availability of office equipment at the workplace, small mechanization for caring for patients with sufficient provision of personal protective equipment, tools, antiseptics and disinfectants. Conclusion. A harmful psychophysiological production factor in the professional activities of nursing personnel is also manifested in significant intellectual and emotional stress, which, over time, also cause the development of any somatic disease in specialists.

Public Transportation Network Design and Frequency Setting: Pareto Optimality through Alternating-Objective Genetic Algorithms

The transportation network design and frequency setting problem concerns the optimization of transportation systems comprising fleets of vehicles serving a set amount of passengers on a predetermined network (e.g., public transport systems). It has been a persistent focus of the transportation planning community while, its NP-hard nature continues to present obstacles in designing efficient, all-encompassing solutions. In this paper, we present a new approach based on an alternating-objective genetic algorithm that aims to find Pareto optimality between user and operator costs. Extensive computational experiments are performed on Mandl’s benchmark test and prove that the results generated by our algorithm are 5–6% improved in comparison to previously published results for Pareto optimality objectives both in regard to user and operator costs. At the same time, the methods presented are computationally inexpensive and easily run on office equipment, thus minimizing the need for expensive server infrastructure and costs. Additionally, we identify a wide variance in the way that similar computational results are reported and, propose a novel way of reporting benchmark results that facilitates comparisons between methods and enables a taxonomy of heuristic approaches to be created. Thus, this paper aims to provide an efficient, easily applicable method for finding Pareto optimality in transportation networks while highlighting specific limitations of existing research both in regards to the methods used and the way they are communicated.

The Lockdown and Smart Working Effects on Electric Energy Consumption: The Analysis for a Group of Employees

The COVID-19 pandemic has accelerated the use of smart working: the working activity carried out also outside the office and not only at the office. This has interesting consequences also on the energy sector, since it can decrease commuting consumption and shifts electric consumption from the tertiary to domestic sector. In this work the electric consumption performance of a (representative) group of 10 employees, working with classical office equipment, has been investigated. The variation of the electric load curves has been analyzed in the office and at home before, during and after the 2020 lockdown restrictions introduced by the Italian government. Consumption changes, with respect to the previous year, have been analyzed and discussed. The variations of the electric load curves affect, in case of adoption of PV (photovoltaic) panels, PV self-sufficiency and PV self-consumption. In the case considered, while the former does not vary significantly (with values of about 40-50%), the latter decreases, in case of the office building, from 44% to 24% and it increases, in case of households, from 32% to 50%. These consequences have to be taken into account when programming new PV plant installations.
