“…Among the many environmental problems of the modern world (Ziarati et al, 2020;Vambol et al, 2019;Mozaffari et al, 2020), one of the important ones is noise pollution (Lauper et al, 2016;Lumnitzer et al, 2018). Noise sensitivity manifests itself through irritation, which can be considered a health-related marker of environmental noise exposure.…”

Among the many environmental problems of the modern world one of the important ones is noise pollution. Currently, noise pollution from vehicles requires special attention in densely populated and industrial cities, as there is a trend towards an increase in the areas of acoustic discomfort in built-up areas. The noise that occurs on the roadway of the highway extends not only to the territory near the highway, but also deep into the housing development. Study' objective was to assess noise pollution from vehicles in the most densely populated area of Poltava (Ukraine), as well as to establish the possibility of influencing the situation through legal mechanisms to have an understanding of further research directions and ways to achieve a comfortable urban environment in Ukraine. The noise levels from traffic flows were measured in accordance with GOST 20444-2014, using the Testo 815. To determine the equivalent noise level from the traffic flows movement, an empirical dependence was applied in accordance with the methodology of the State Agency for Highways of Ukraine. Determined that the daytime threshold values are exceeded by 20–28.9 dB(A), which is not acceptable. The reasons for the increase in noise are the road bumps, a significant number of cars and number of stops and streets junctions, the movement of vehicles at a non-constant speed, lack of roadside landscaping. About 62,550 people live in areas where the noise level exceeds the permissible value for the area near residential buildings. The calculation method used turned out to be more accurate than the measured results and showed a significant effect of traffic intensity on noise pollution. Apparently, the low measurement accuracy is justified by outdated road noise measurement standards, which, in turn, need to be seriously revised. Reducing noise levels by optimizing traffic flows is one of the priority areas in which it is necessary to bring the environmental legislation of Ukraine. Ukrainian legislation still needs to undergo many changes to reach a level where it can be used as a control lever to achieve a safe ecological environment.

“…The foundation of the main idea of balanced thinking is to maintain a balance between the social, economic, and ecological dimensions (Aguilar-Salinas, et al, 2017; Armeanu et al 2017). It is in particular important for the factors that cause increasingly use of natural resources, which are hardly renewable, for example, the evolution of civilization, massive population growth, or high demand of recipients (Pacana, Siwiec, Bednárová, 2020;Pacana et al, 2014;Lumnitzer et al, 2018). Currently, activities are related, among others, to the use of renewable energy sources, the use of ecological materials, or the strict adherence to the principles of recycling.…”

“…A favorable phenomenon is the growth of companies that are certified in accordance with applicable environmental protection programs (Malindzak et al, 2017;PN-EN ISO 14001:2015). One of the stages that occur in the process of evolution of environmental management in Poland is: dilution, filtration, cleaner production, product life cycle management, as well as renewable energy and environmental management strategies (Armeanu et al 2017;Pacana, Siwiec, Bednárová, 2020;Lumnitzer et al, 2018;Gherghina, Vintilă, 2016). These actions are realized according to the philosophy of sustainable development under which popular techniques are practiced for example, Clean Production (CP) and EMAS systems (Eco-Management and Audit Scheme) (Budynek et al, 2014;Siwiec, Pacana, 2021a, 2021bMasternak, 2009).…”

The paper investigates challenges associated with institutional leadership engagement of main staff to fill inner vacancies. Design/methodology/approach: The study rates merit, experience, rank, competencies, long service, in-depth knowledge, and deeper consultation as key requirements for appointment in some selected academic institutions. The survey collects data through questionnaires and semistructured interviews. The SPSS and descriptive statistics were used for the analysis of data presented in percentages, tables, and graphs. Findings: The results show that over 80% of respondents said that the prerogative of leaders in second-cycle institutions to share leadership needs a reassessment. As it undermines specific parameters and subsequently creates emotions among staff and unsatisfactory students' behaviours at school. The study found social and external factors as the basis for some nominations that weaken institutional unity and performance. Recommendation/limitations: The legislative instrument should be amended to suit the current management environment. Besides, ethical leadership and emotional intelligence should be encouraged at schools for effective management and harmony. Practical implications: Organizational failures across economies to a large extent are results of stimulus variables. Originality/value: The paper demonstrates how institutional leaders are often torn between stimulus and prospective variables resulting in self-interest to the detriment of institutional vision.

Efforts to develop effective and innovative materials are increasingly being developed by researchers, especially in the development and utilization of NFRP (Natural Fiber Reinforced Polymer) in the automotive sector due to increased demand and increased ecological awareness. The purpose of this literature review article is to provide up-to-date information on the application of NFRP and plastic recycling in the automotive sector as well as consideration of selecting natural fibers for use as reinforcing composites in the automotive sector. This literature review focuses on the progress of the development of polymeric materials applied in the automotive field. Referring to defined inclusion and exclusion criteria, 30 articles in polymer composite studies published between 2015 and 2020 were selected for further investigation. The analysis of selected studies revealed that several leading car manufacturers have produced and developed products from NFRP or recycled plastics with natural fiber reinforcement because they are relatively cheap, lightweight, and able to reduce exhaust emissions. The great potential of using NFRP materials and recycled plastics in the automotive sector presents a future challenge, namely the increasing need for natural fiber in the long term which will certainly have an impact on ecosystems and biodiversity.
