Ukrainian short-distance runners’ performances (men and women) at the Olympic Games and World Championships during the period of 1992 – 2019 have been analyzed. The dynamics of their results in 100-200m running was identified as well as the reasons for going behind world’s leading runners. Peculiarities of performing fairly precise movements at high speeds, specific character of showing speed in a sprint race and phases of acceleration and deceleration were characterized. This should be taken into consideration in the process of choosing major training exercises, improving speed abilities of athletes. The results of the Ukrainian sprinters show that the methodological component of the development of the speed quality used by the coaching staff was in the leading positions in Europe and in the world. The current level of training of Ukrainian short-distance runners leaves much to be desired for various reasons, one of which, in our opinion, is the main one - an increase in the unjustified intensification of short-distance runners training in the initial stages of the multi-year training process. This approach led to a decrease in normative results in sprint racing, as well as to the lack of purposeful methodological support and system of realization of accumulated knowledge on development and improvement of one of the basic physical abilities - quality of speed. At the present stage, this problem is a major one and requires a comprehensive study and training of the coaching staff to develop a better organization of the training process in sprint racing. These characteristics of sprint running give us the opportunity, on the one hand, to correctly evaluate the prospective indicators of the sprinter body (total body length, legs, their ratio, type of nervous system, etc.), and on the other - with high accuracy of adequacy to select the main training tools and methods of their application. that will improve the quality of speed and, as a consequence, increase the speed of running.

Issues of improving the functional training (different orientation of the training process) of athletes due the development of the respiratory system, including the respiratory system, as well as increasing the body's resistance to hypoxic stress remain extremely relevant at the present stage of sport development. The aim of the study is to investigate the peculiarities of the reaction of the external respiratory system in athletes, depending on the orientation of the training process. Materials and methods. The study involved 104 athletes (84 men and 20 women) skill level from CMS to IMS: 63 – athletes, who developed mainly endurance quality (triathletes, swimmers, long-distance runners, rowing), 31 – strength quality (weightlifters, powerlifting, weightlifting), 10 – speed quality (runners sprinters). The mean age of the athletes under study was 21.75 ± 3.32 years. Among them there are international masters of sports (IMS) – 2 athletes, masters of sports (MS) – 25, candidates for master of sports – 48, athletes of 1 degree – 29. Computer spirometric examination was performed for all athletes using the spirographic complex “Spirocom” produced by LLC “KHAI-Medica” in Kharkiv in accordance with existing recommendations. Research results. Analysis of computer spirometry showed, that athletes, who developed the quality of strength had 18.2 % (P = 0.014) greater vital capacity of the lungs, due to the predominance of respiratory volume by 29.9 % (P = 0.017) and by 42.1 % (P = 0.001) inspiratory reserve volume, but less by 22.4 % (P = 0.019) expiratory reserve volume, than athletes, who improved the quality of endurance. Athletes, who developed the quality of endurance in contrast to athletes, who improved the quality of speed had a higher forced vital capacity of the lungs by 14.9 % (P = 0.031), due to the predominance of a inspiratory reserve volume by 9.8 % (P = 0.049) and expiratory reserve volume by 28.5 % (P = 0.044). Athletes, who improved the quality of speed had lower vital capacity of the lungs by 26.1 % (P = 0.003), forced vital capacity of the lungs by 20.2 % (P = 0.016), due to a decrease of inspiratory reserve volume by 34.2 % (P = 0.008), than athletes, who improved the quality of strength. Athletes, who developed the quality of speed, had greater resistance to air flow in the bronchi of small caliber in the exhalation phase, as evidenced by a lower rate of forced expiratory volume1 by 21.1 % (P = 0.015), the volume of forced expiratory to reach the peak expiratory flow by 30.2 % (P = 0.016), MEF 75 by 22.9 % (P = 0.036), FEF 75–85 by 22.8 % (P = 0.035), than athletes, who developed the quality of strength. Conclusions Athletes, who have developed a quality of strength have a greater vital capacity of the lungs, due to the predominance of respiratory volume and inspiratory reserve volume, but less expiratory reserve volume, than in athletes, who improved the quality of endurance. Athletes, who developed endurance quality, in contrast to athletes, who improved the quality of speed, have a higher forced vital capacity of the lungs, due to the predominance of inspiratory and expiratory reserve volumes. The function of external respiration of athletes, who improved the quality of speed is characterized by lower vital capacity of the lungs, forced vital capacity of the lungs, due to reduced inspiratory reserve volume, and greater resistance to airflow in the bronchi of small caliber in the expiratory phase, than in athletes, who developed the quality of strength.

An attempt is made to supplement and expand the understanding of the organizationof the training process of athletes (at the stage of initial training) with special means using thegame method. In a pedagogical experiment on 48 athletes (boys and girls), the effectiveness of theexperimental methodology was determined, including: blocks of outdoor games aimed at developingelementary and complex types of speed abilities; sets of conjugate development exercises (running+ jumping); relay races to prevent the formation of a “speed barrier” from hill to hill 6x40 meters, aswell as a relay race with a handicap of 4x50 meters, to increase motivation for training sessions, etc.Correlation analysis between the recorded indicators has been carried out.The effectiveness of the experimental method (p<0.05), aimed at developing the speed abilitiesof athletes of 10–12 years old, using the game method was revealed. Correlation analysis showedthat after the pedagogical experiment there was a change in the structure of correlations betweenthe studied indicators in both groups: during the training process, some connections disappeared,others appeared.Our studies allow us to assert that the use of more games for the development of speed andreaction speed will improve the results of short-distance runners without forcing special training(p<0.05).

Marine representatives of the phylum Gastrotricha are reported for the first time from the State of New Jersey, USA. Littoral and shallow sublittoral sediment collected at Ship Bottom on Long Beach Island, near Atlantic City, yielded 11 species belonging to eight genera in six families in the orders Macrodasyida (four genera in three families) and Chaetonotida (four genera in three families). Littoral samples were richer than the one sublittoral sample (7 vs 4 spp.). Among the taxa was a large, undescribed species of Tetranchyroderma characterized by the following key traits: total body length up to 605 μm; cuticular covering complete, made up of pentancres; a pair of cephalic tentacles; dorsal adhesive tubes arranged in dorsal and dorsolateral columns; a pair of ventral adhesive tubes arising from a common base, near the perigenital area only on the right side; peculiar cuticular openings ‘stomata’ along the ventrolateral margins of the body; protogynous hermaphroditism. Tetranchyroderma weissi sp. nov. is, at least in the investigated location, restricted to the sediment layers below 20 cm of the intertidal zone, and is able to live in thiobiotic sediment. A key to the described species of the world based on easily discernible traits, visible in both living and formalin-fixed specimens is provided.

Subject. The study addresses the improvement of risk management efficiency and the quality of lending decisions made by banks. Objectives. The aim is to present the bank management with a fair algorithm for risk management motivation on the one hand, and the credit management (business) on the other hand. Within the framework of the common goal to maximize risk-adjusted income from loans, this algorithm will provide guidelines for ‘risk management’ and ‘business’ functions on how to improve individual and overall efficiency. Methods. The study employs the discriminant analysis, type I and II errors, Lorentz curve modeling, statistical analysis, economic modeling. Results. The paper offers a mechanism for assessing the quality of risk management decisions as opposed to (or in support of) decisions of the lending business when approving transactions. The mechanism rests on the approach of stating type I and II errors and the corresponding classical metric of the Gini coefficient. On the ‘business’ side, the mechanism monitors the improvement or deterioration of the indicator of changes in losses in comparison with the market average. Conclusions. The study substantiates the stimulating ‘rules of the game’ between the ‘business’ and ‘risk management’ to improve the efficiency of the entire business, to optimize interactions within the framework of internal competition. It presents mathematical tools to calculate corresponding indicators of the efficiency of internally competing entities.

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.
