The objective is to empirically investigate statistically significant correlations and elucidate determinants of high and low anxiety parameters within the motivational orientation dimensions of junior athletes. The study encompassed male and female junior athletes (n = 96) (Мe = 17; М = 17.38; SD = ±1.71) representing individual sports from sports schools for children and young people – “SSSYOR №1” in Ivano-Frankivsk, Ukraine and “LSSCY Enerhetyk” in Lviv, Ukraine – and youth academies of professional handball clubs: “HC Dniprianka” in Kherson, Ukraine and “HC Real” in Mykolaiv, Ukraine and football club “FC Enerhiya” in Lviv, Ukraine. Methods: valid and reliable methods were applied to find the parameters of anxiety and motivational orientation of the respondents before the beginning of the game. Additionally, a planned observation with standard blanks was used. Statistical coefficients were used to establish significant correlations. Results. It was found that the junior athletes with a low level (Group 1) of the parameters of anxiety have an advantage in the level of motivation over the athletes with a high level (Group 2). A lack of advantage in the parameters of situational and personal social protection – SSP (U = 623.50; p = .549) and PSP (U = 532.00; p = .091) – was explained by an equally important impact of this protection for the respondents with a high level and those with a low level. It was proved that high and low psychological content parameter of anxiety have statistically significant correlations with the respondents’ motivational orientation: Group 1 – thirty correlations; Group 2 – twenty seven correlations. It was empirically established that situational (SAEP) and personal (PAEP) anxious evaluation of prospects has a positive impact on subject-directed (SbM) and socially-directed (ScM) motivational orientation in the two research groups. Discussion and conclusions. It was substantiated that the impact of the parameters of SAEP and PAEP are within the scope of a personal choice, social pressure and an athlete’s construction of the future that requires psychological assistance and support of coaching and teaching staff. It was highlighted that the impact of spectators, social pressure of mass-media, expectations of fans, coaching staff and management of an organization (sports school/professional club) and junior athletes’ aspirations to meet other peoples’ expectations are wrong tactics and strategies of training and competitive process. We can generalize that anxiety is a multifaceted phenomenon in the dimensions of motivational orientation of junior athletes combining a complex of internal and external factors determining psychophysiological reactions of a junior athlete’s body and their motivational orientation. We recommend that the obtained results should be taken into consideration by coaches working with juniors
AUTOMATIC PREVENTION OF THE VESSEL’S PARAMETRIC ROLLING ON THE WAVE
(2024) Kobets, V.; Zinchenko, S.; Tovstokoryi, O.; Nosov, P.; Popovych, I.; Попович, I.; Gritsuk, I.; Perederyi, V.
Parametric resonance is one of the most dangerous phenomena that occurs during a storm. In the event of a parametric resonance, an undamaged and properly loaded vessel can capsize within seconds. The essence of parametric resonance is to change the parameters of the vessel as an oscillating system. In this case, the coefficients of the differential equations of the vessel model become functions of time. Parametric oscillations are observed at a certain ratio between the frequency of the external influence and the frequency of the system's own oscillations. Parametric resonance in the roll channel is especially dangerous, which leads to a sharp increase in the amplitude of the vessel's rolling, water entering the deck and inside the vessel's hull, loss of stability and possible capsizing. The existing methods of storming are not effective enough, which is due to the use of visual methods for estimating the parameters of turbulence and manual graphic constructions, significant time delays between obtaining data for calculation and determining safe parameters of motion, the lack of constant measurement of turbulence parameters and refinement of safe motion parameters, the difficulty of selecting the dominant factor from the system dangerous factors, intuitive assessment of the level of danger. The authors have developed a method of automatic avoidance of parametric resonance, which differs from existing methods in that it automates the processes of measurement and information processing, reduces delays in decision-making, reduces the influence of the human factor on control processes, reduces crew fatigue, reduces the risks of losing the vessel and cargo, and in general increases the navigation safety. The developed method can be used for both manual and automatic control. In the manual control mode, the shipmaster has the opportunity to use automatically measured information and the results of its processing - visualization of parametric resonance areas and the position of the phase point for making management decisions. In the automatic control mode, the system itself calculates and implements safe movement parameters, and the shipmaster only observes its operation. The obtained results are reproducible and can be used to develop the functionality of automated systems and/or automatic parametric resonance avoidance modules.
DEVISING AN APPROACH FOR THE AUTOMATED RESTORATION OF SHIPMASTER’S NAVIGATIONAL QUALIFICATION PARAMETERS UNDER RISK CONDITIONS
(2024) Ponomaryova, V.; Nosov, P.; Ben, A.; Popovych, I.; Попович, I.; Prokopchuk, Y.; Mamenko, P.; Dudchenko, S.; Appazov, E.; Sokol, I.
The object of this study is the safety control system of ship management, by identifying and restoring the qualifica tion parameters of shipmasters in criti cal situations. The task solved in the study is the timely determination of an insufficient level of qualification for the perfor mance of certain operations in con trolling the movement of the ship, by applying a formal-logical model of de tecting the intuitive actions of the ope rator-shipmaster and gradually restor ing his/her qualification parameters using the devised method. The stages of development and the formal-logical structure of the model and method in terms of cognitive auto mation were described in detail as the study results. It was possible to ensure early detection of risks when controlling the movement of the ship in 56 % of cases, during a laborato ry experiment on simulators, which in 24 % of cases turned out to be particu larly dangerous. The interpretation of the results in volved algorithmizing complex and for malized data on the actions of opera tors and the application of the method of restoring their qualification para meters, which allowed a comprehensive approach to safety management. The distinguishing features of the findings were to predict the level of danger by simulating maritime opera tions with input navigational and indi vidual conditions. This made it possible to improve the effectiveness of ope rations to 89 %, reduce the phenome non of loss of control over the course to 32 %, reduce critical situations to 7 % and the cost of resources. The scope and conditions of practi cal use involve a comprehensive assess ment of external and internal influ ences on the level of danger, delay in decision-making by operators, as well as sailing conditions. The simulation results could be used to devise strate gies for planning maneuvers, predicting risks, and developing maritime securi ty systems
IMPACT OF EMOTIONALITY AND LOCUS OF CONTROL ON ATHLETES’ MOTIVATION FOR SUCCESS ACHIEVEMENT AND FAILURE AVOIDANCE IN INDIVIDUAL SPORTS
(2024) Popovych, I.; Bokhonkova, Y.; Sokolova, H.; Forostian, О.; Rodchenkova, I.; Yurkiv, Y.; Korniienko, I.; Попович, I.
This study aimed to identify statistically significant parameters regarding the influence of emotionality and locus of control on athletes' motivation for success achievement and failure avoidance in individual sports. The sample consisted of athletes participating in individual sports (n = 123) with a mean age of 23 (Me = 23; M = 23.19; SD = ±2.92), representing disciplines such as artistic gymnastics, track and field, weightlifting, freestyle wrestling, and boxing. Among the participants were medalists and winners of regional, national, international, and Olympic sports competitions. Methods. The methods verified in sports studies allowed measuring a number of parameters of emotionality and locus-control, and also two dependent variables – motivation for achieving success and avoiding failure. Statistically significant differences were identified by standard coefficients. Results. It was empirically established that both dependent variables have a considerable number of statistically significant correlations (p ≤ .050; p ≤ .010): motivation for achieving success has eight correlations, motivation for avoiding failure has seven correlations. It was found that three parameters – “athletes’ emotional stability”, “area of athletes’ achievements” and “athletes’ health and illnesses” correlate significantly with both motivations: motivation for achieving success (MAS) and motivation for avoiding failure (MAF). Diametrically opposite correlations of the parameters “athletes’ interpersonal relationships” with MAS (rxy = -.235; p=.041) and MAF (rxy = .215; p = .045) and “athletes’ sporting activities” with MAS (rxy = .623; p = .041) and MAF (rxy = -.238; p=.042) were established. Discussion and conclusions. It was generalized that emotional stability (ES) and emotional arousal (EA) are important parameters of athletes’ emotionality, whose constructive realization is within the scope of emotional intelligence (EQ) and has a statistically significant impact on motivation and achievement of victory. It was explained that support for emotional positive relationships in domination of motivation for achieving success can have a negative effect on athletes’ concentration. Such relationships can be a defense mechanism, emotional comfort and psychological relief in difficult situations of sporting activities in case of domination of motivation for avoiding failure. It was proved that emotionality and locus-control affect motivation for achieving success and avoiding failure of athletes in individual sports. The obtained results are characterized by scientific novelty and can arouse interest in everyone who is involved in training and competition processes of athletes in individual sports.
