Мета. Метою дослідження є вдосконалення економіко-математичної моделі максимізації прибутку підприємства в системі цінностей сталого розвитку. Методологія / методика / підхід. У роботі використано методи системного аналізу, систематизації, узагальнення та конкретизації, графічний метод і метод порівняння (процесів, показників тощо), а також економіко-математичні методи моделювання систем та експертні методи. Результати. Удосконалено структурну схему (триконтинуумну модель як концептуальну схему інформаційної технології) керування фінансовими і технологічними процесами, інноваційними ризиками, яка враховує вплив інновацій на діяльність (внутрішні змінні, бізнес-процеси) підприємства, обмеження (за виробництвом, реалізацією, постачанням, фінансами) і умови їх дотримання при оптимальному обсязі виробництва (реалізації), а також синергетичний ефект у контексті максимізації прибутку, у системі «вид інновації – вид розвитку», у системі цінностей сталого розвитку. Ця структурна схема є основою запропонованої економіко-математичної моделі максимізації прибутку підприємства в системі цінностей сталого розвитку. Запропоновано мультиплікативний критерій ефективності менеджменту, який включає методики визначення рівня якості розвитку підприємства та керування розвитком підприємства в системі «вид інновації – вид розвитку». З’ясовано, що рівень якості розвитку підприємства (у системі виробничого менеджменту і з урахуванням системи цілей маркетингу) залежить від: рівня ритмічності і бездефектності виробництва продукції; рівня задоволення потреб споживачів готовою продукцією. Оригінальність / наукова новизна. Удосконалено економіко-математичну модель максимізації прибутку підприємства в системі цінностей сталого розвитку, яка базується на теоретичних і прикладних засадах менеджменту, маркетингу, ураховує особливості системи діагностичних цілей економічної діагностики, інструментарій моніторингу параметрів діяльності підприємства, їх взаємозв’язок, а також містить окремі положення теорії обмежень, методи оптимізації та економіко-математичного моделювання, і, на відміну від наявних, з огляду на дослідження операцій, дозволяє розв’язати загальну економічну задачу на практиці – максимізувати прибуток підприємства в системі цінностей сталого розвитку. Практична цінність / значущість. Результати дослідження можуть бути використані в практичній діяльності підприємств усіх форм власності.

This article defines SCATT optoelectronic system accuracy of weapon movement registration. Three types of errors were found in defining the coordinates of the aiming point on a SCATT target: asymmetry of the left to right and up to down results, absolute errors in each direction and the dependence of the error upon the distance to the centre of the target. It was found that the optoelectronic registration shows the biggest errors in the left and up directions from the centre of the target (199%–283%) and relatively less errors in right (54%–188%) and down (18%–188%) directions. In order to make corrections while defining the aiming point coordinates on a SCATT target, one can use the correction factor based on the distance from the aiming point to the centre of the target.

The study purpose was to prepare a model of the trans-season reliability of physical fitness testing on the example of “Tourism” speciality students. Material and Methods. A total of 50 university first year bachelor’s students studying “Tourism” as a business service were involved in the physical fitness testing: 20 males with body mass 67.3±9.5 kg (M±SD) and body length 174.6±5.6 cm; and 30 females (body mass 59.6±7.3 kg, body length 163.9±5.2 cm). Monthly testing was conducted seven times from September to March using a complex test KONTREKS–2. Trans-season mean score reliability was evaluated within the intraclass correlation model. Results. Approximately 86% of the students were found to be on the average and higher levels and only nearly 5% − on the low level. Males showed significantly better state of the physical fitness than females (16.6%, p < 0.002) with 96.3% similarity of trends in scores between males and females during the trans-season study. A great variation within these samples was noticed, too; a corresponding part in the total variation was derived as 93.6%. A strong and high level significant correlation (r > 0.80, p < 0.001) was determined between all the seven monthly test-retest trans-season trials. Significant trans-season reliability on the excellent level was found for each of two gender samples (ICC > 0.95, p < 0.001). Deviations from mean values for seven monthly tests undertaken during the study period were not significant (chi-squared = 13.939, p = 0.834). Conclusions. A model of the trans-season reliability of physical fitness testing created on the example of the first year bachelor’s students of “Tourism” speciality showed its effectiveness and could be recommended for physical education of high school students.

The purpose of this research is to create a model of interaction between steps/day counts regarding genders, seasons of a year, and days of week. Material and Methods. Totally 74 of 4-th grade pupils (38 boys and 36 girls) from three primary schools in the industrial city were involved into the pedometer investigation. All the students were good healthy, and they participated in the schools’ lessons of physical education according to the common program. Pedometer determined physical activity was measured during a day using fitness tracker band. The measurements were done during one academic year using three full weeks (a week in autumn, winter, and spring). ANOVA was used to determine differences between samples grouped according days of weeks. Results. A strong significant difference between counts of steps during days of week for boys (p = 0.006) and smaller for girls (p = 0.052) were discovered with corresponding parts in the total variation (62.5 and 46.0 %). The same significant differences were discovered between mean counts in seasons (p = 0.053, 0.037) with corresponding parts in the total variation (14.5, 22.8 %). Rather significant variations of interaction between days of week and mean season results took place for boys (23.0%) as well for girls (31.1 %). Conclusions. During evaluation of physical activity in children based on steps/day counts, interaction between gender, season, and day of week should be taken into consideration.

Purpose: The paper is dedicated to the problem of testing physical capacity in primary school with the use of the Ruffier-Dickson test. The research aimed to verify the Dickson index corrected for the children’s age with the intention of usage in primary school physical education.Methods: Four groups of healthy males – aged 6, 7, 8, and 18 years – were randomly selected, 30 participants in each. One way ANOVA, t-test for independent samples, and intra-correlation coefficient were used to evaluate the validity of the Dickson index for the original and age-corrected functions. It was assumed that Dickson index values should not depend upon age among healthy participants in normal physical capacity.Results: Invalidity of the original Dickson index for 6–8-year-old children was shown, with a significant difference of their results from those of the adults (p < 0.001). The use of the index formula corrected for the age of children gives no significant difference between all the groups (p = 0.817) and a good level of validity, taking into consideration the corresponding intraclass correlation coefficient of 0.688. This conclusion is supported with t-test results (p = 0.915), which show a rather good level of the test validity.Conclusions: To guarantee the validity of the Dickson index, the results of heart rate measurements should be reduced proportionally to the ratio of a normal heart rate of the young patients’ population to the normal heart rate in adults.

Background and Study Aim. It is widely used a paradigm about the interdependence between the academic and sport achievements of students. The aim of this research was to create a model for studying relationships between academic and sport achievements of the sports and physical culture university students. Material and Methods. Totally 259 (168 male and 91 female) bachelor students of 18–23 years old studied Physical Culture and Sports were involved into the investigation. All the students were good healthy, and they participated in the sport training and competitions, according the common program. Interdependence between the semester control scores and scores of the sport achievements were studied in the frames of correlation models of parameter and non-parameter statistics. Distribution of scores was studied using Kolmogorov – Smirnov method. One-way ANOVA for repeated measures was used to determine differences between students’ scores and educational disciplines’ scores. Results. Almost non-significant weak interdependence between results of the semester control and sport achievements was noticed (р>0.05, 0.174≤rs≤0.284). There were no statistically significant and tight correlation between semester control scores of educational disciplines and corresponding sport achievements scores (|rs|≤0.376). Contrary, in 73% of educational disciplines pairs the semester control scores showed significant and tight correlation (p<0.001, 0.385≤r≤0.895). Conclusions. A well-known paradigm about significant relationship between academic and sport achievements of students was not confirmed with the results of this research and should be studied more profoundly.
