The article presents information on the current state of keratobioimplants production and clinical use in Ukraine. Thanks to the cooperation of the State Enterprise Bioimplant of the Ministry of Health of Ukraine with 13 ophthalmological institutions, keratobioimplants have been successfully used to treat corneal diseases since 2014. Over 7 years the enterprise has manufactured and provided for treatment 1799 keratobioimplants from the donor cornea of the human eye for various types of keratoplasty.The donors were analyzed by age, infection level, optimal timing of keratolimbal discs retrieval as well as morphometric parameters of endothelial cells.Long-term clinical outcomes demonstrate high quality of engraftment and steady increase in visual acuity in patients after penetrating keratoplasty. In 99.4% of the patients undergoing curative keratoplasty, the inflammatory process was stopped, the destruction of the cornea was stopped, and the eyes were preserved for further surgical ophthalmological interventions.

Podkarpackie Voivodeship is one of the regions of Poland in which the number of agritourism entities is very high. Therefore tourism plays a significant role in its development strategy. The aim of the paper is to identify the current state of agritourism and the changes that have occurred in the region in the years 2000–2016. Specific objectives are to determine the distribution of agritourism farms and their offer, together with a comprehensive analysis of the environmental and socio-economic factors, as well as the impact of the Slovak-Ukrainian border. The report was developed on the statistical materials from the Polish Central Statistical Office, Podkarpackie Agricultural Advisory Centre in Boguchwała and data collected from municipalities and district offices that is published on their websites, as well as through interviews with 100 owners of agritourism farms in the Podkarpackie Voivodeship. The research has shown, on the one hand, the decline in the number of farms in the region and, on the other hand, the increase in the diversity of the tourist offer of these entities. Distribution of agritourism farms is closely linked to the attractiveness of natural environment and quality of secondary tourism resources. Traditional agritourism has not yet fully used its countryside, as well as cross-border advantages of its location.

The article discusses the current state of professional training of engineers, in particular, electronics engineers in Ukrainian higher education institutions (HEIs) and explores best practices from US HEIs. The research outlines the features of professional training of electronics engineers and recent changes in Ukrainian HEIs. Such challenges for Ukrainian HEIs as lack of collaboration between higher education and science with industry, R&D cost reduction for HEIs, and downsizing the research and academic staff, the disparity between the available quality of human capital training and the demanded are addressed. The study attempts to identify successful practices of US HEIs professional training of engineers in order to suggest potential improvements in education, research, and innovation for training electronics engineers in Ukraine.

The article considers the current state of the Russian language. Information technologies in the twenty first century present diverse forms of linguistic knowledge and modalities of knowledge quantisation in a linguistic sign. The Russian language develops from a standard, direct expression of thoughts to a nonstandard, psychologically complex, associative deep statement of thoughts. In the early nineteenth century, during the democratisation of the Russian language, a national genius, Alexander Pushkin, emerged. Thanks to him, the unique informational, cultural, and artistic evolution of the language took place. Nowadays, while democratisation and globalisation, processes which resemble the language evolution 200 years ago, are occurring. These processes suggest some patterns: overcoming stylistic disparity, changes in linguistic sign boundaries and semantic extension.

The presented study aims to examine the current state and development prospects of self-regulation in the Russian construction industry.Aim. The study aims to conduct a comprehensive analysis of the current state and development prospects of self-regulation as an institution of public administration, identify the problems of self-regulation in the construction industry, and formulate proposals on solving the identified problems.Tasks. The authors complete the following tasks to achieve the set aim: examine the regulatory framework of the activities of self-regulatory organizations in the construction industry — construction, design, and engineering surveying; analyze the current state and positive trends of self-regulation in the field of construction; identify problems in the activities of self-regulatory organizations in the construction industry — construction, design, and engineering surveying — and development prospects of the examined alternative to government regulation.Methods. The methodological basis of the study comprises the fundamental provisions of the modern economic theory, theories of public and municipal administration and legal sciences. The information base includes regulatory and legal acts of the Russian Federation on self-regulation in the construction industry, data from the State Register of Self-Regulatory Organizations, and statistics in the field of construction.Results. At the current stage of development of self-regulation in the construction industry, the most efficient mechanism for this institution involves guaranteed compensation for damage caused due to shortcomings in the works and services during construction, renovation, capital repairs of construction objects, engineering surveying, design. The victims should be compensated not out of insurance payments under civil insurance contracts, but rather out of the compensation funds of self-regulatory organizations.Conclusion. This study makes it possible to assess the institution of self-regulation in the construction industry — construction, design, and engineering surveying — as an efficient institution for proper protection of the interests of consumers of construction works and services and those of the government.

 Aspire of the Drug Utilization Studies (DUS) is to appraise factors related to the prescribing, dispensing, administering and taking of medication, and it’s associated. Since the middle of twentieth century, interest in DUS has been escalating, first for market-only purposes, then for appraising the quality of medical prescription and comparing patterns of use of specific drugs. The scope of DUS is to evaluate the current state and future trends of drug usage, to estimate roughly disease pervasiveness, drug expenditures, aptness of prescriptions and adherence to evidence-based recommendations. The increasing magnitude of DUS as a valuable investigation resource in pharmacoepidemiology has been bridging it with other health allied areas, such as public health, rational use of drug, evidence based drug use, pharmacovigilance, pharmacoeconomics, eco-pharmacovigilance and pharmacogenetics.

The authors describe a software suite for determining tilt degrees of tower-type structures according to ground laser scanning indication. Defining the tilt of the pipe is carried out with a set of measured data through approximating the sections by circumferences. They are constructed using one of the simplest search engine optimization methods (evolutionary algorithm). Automatic filtering the scan of the current section from distorting data is performed by the method of assessing the quality of models constructed with that of least squares. The software was designed using Visual Basic for Applications. It contains several blocks (subprograms), with each of them performing a specific task. The developed complex enables obtaining operational data on the current state of the object with minimal user participation in the calculation process. The software suite is the result of practical implementing theoretical developments on the possibilities of using search methods at solving optimization problems in geodetic practice.

AbstractIt is well known that the surface topography of a part can affect its mechanical performance, which is typical in additive manufacturing. In this context, we report about the surface modification of additive manufactured components made of Titanium 64 (Ti64) and Scalmalloy®, using a pulsed laser, with the aim of reducing their surface roughness. In our experiments, a nanosecond-pulsed infrared laser source with variable pulse durations between 8 and 200 ns was applied. The impact of varying a large number of parameters on the surface quality of the smoothed areas was investigated. The results demonstrated a reduction of surface roughness Sa by more than 80% for Titanium 64 and by 65% for Scalmalloy® samples. This allows to extend the applicability of additive manufactured components beyond the current state of the art and break new ground for the application in various industrial applications such as in aerospace.

Olfaction, the sense of smell, is characterized by a notable age-dependency such that aging individuals are more likely to have poor olfactory abilities. These impairments are considered to be mostly irreversible and as having potentially profound effects on quality of life and food behavior, as well as constituting warning signs of mortality, cognitive dysfunction, and dementia. Here, we review the current state of research on aging and olfaction, focusing on five topics which we regard to be of particular relevance for the field: nutrition and health, cognition and dementia, mortality, environment and genetics, and training-based enhancement. Under each of these headlines, we provide a state-of-the-art overview and discuss gaps in our knowledge which might be filled by further research. Understanding how olfactory abilities are diminished in aging, and how they may be alleviated or recovered, involves a set of challenging tasks for researchers in the years to come.
