No full textCultural and creative potential of Ukrainian cinema science: experience 2000 - 2010 years The article gives an analysis the concepts of the Ukrainian film experts of the first decade of XXI century, reflecting the new aspects of the theoretical approaches in both history of the Ukrainian cinema and the contemporary cinematic trends. Analyzed the works of famous Ukrainian film critics of the older generation - M. Braterskaya-Dron, L. Bryukhovetskaya, I. Zubavina, O. Musienko, A. Rutkovsky, V. Skuratovsky, S. Trymbach, A.

FINANCIAL ANALYSIS AND FORECASTING OF THE RESULTS OF SMALL BUSINESSES PERFORMANCE BASED ON REGRESSION MODEL
No full textObjective: to develop the economic-mathematical model of the dependence of revenue on other balance sheet items, taking into account the sectoral affiliation of the companies.Methods: using comparative analysis, the article studies the existing approaches to the construction of the company management models. Applying the regression analysis and the least squares method, which is widely used for financial management of enterprises in Russia and abroad, the author builds a model of the dependence of revenue on other balance sheet items, taking into account the sectoral affiliation of the companies, which can be used in the financial analysis and prediction of small enterprises’ performance.Results: the article states the need to identify factors affecting the financial management efficiency. The author analyzed scientific research and revealed the lack of comprehensive studies on the methodology for assessing the small enterprises’ management, while the methods used for large companies are not always suitable for the task. The systematized approaches of various authors to the formation of regression models describe the influence of certain factors on the company activity. It is revealed that the resulting indicators in the studies were revenue, profit, or the company relative profitability. The main drawback of most models is the mathematical, not economic approach to the definition of the dependent and independent variables. Basing on the analysis, it was determined that the most correct is the model of dependence between revenues and total assets of the company using the decimal logarithm. The model was built using data on the activities of the 507 small businesses operating in three spheres of economic activity. Using the presented model, it was proved that there is direct dependence between the sales proceeds and the main items of the asset balance, as well as differences in the degree of this effect depending on the economic activity of small enterprises.Scientific novelty: the article presents a regression model of dependence of revenues on the major categories of assets for small businesses based on the principles of economic expediency, not of mathematically correct dependencies.Practical significance: the main findings of this paper can be useful in the practical management of small businesses, for financial analysis and forecasting, in particular in the benchmarking of companies in certain sectors. In addition, the results of this research can be used in scientific and teaching activities in covering the issues of financial management of small businesses
Conserving surgery for iatrogenic defects of the maxillary sinus
No full textA rationale for the choice of the method of primary plastics perforation of the maxillary sinus defects of different etiology. The study Included 292 patients of both sexes aged 19-72 years who in the course of surgical intervention been opened maxillary sinus: at 80 - in the formation of access for the removal of cysts (30 in a conventional manner, endoscopic (FESS) - 30, osteoplastic by ultrasound NV Mishenkin • 30); In 212 - during the removal of the tooth (37 patients without restoring bone wall, 175 with the restoration of the authors' methodology with platelet plasma (patent 2,380,052). When using the osteoplastic ultrasonic method for accessing the maxillary sinus catarrhal, purulent and subatrophic changes in the nasal mucosa observed 4.5 times less than the traditional access and 3.8 times less than in FESS. results perforated plastic defect using the platelet plasma by the method of Al and AA Musienko 12 times better than traditional treatment group.Цель работы - обоснование выбора метода первичной пластики перфорационных дефектов верхнечелюстной пазухи различной этиологии. Под наблюдением находились 292 пациента обоего пола в возрасте 19-72 лет, у которых в процессе хирургического вмешательства вскрывалась верхнечелюстная пазуха: у 80-ти - при формировании доступа для удаления кисты (традиционным способом 30, эндоскопическим (ФЭСХ) - 30, остеопластическим ультразвуковым по Н.В. Мишенькину - 30); у 212 - во время удаления зуба (37 пациентам без восстановления костной стенки, 175 с восстановлением по авторской методике с тромбоцитарной плазмой (патент 2380052). При использовании остеопластического ультразвукового способа для доступа в верхнечелюстную пазуху катаральные, гнойные и субатрофические изменения слизистой оболочки полости носа отмечались в 4,5 раза реже, чем при традиционном доступе и в 3,8 раза реже, чем при ФЭСХ. Результаты пластики перфоративного дефекта с использованием тромбоцитарной плазмы по методике А.И. И А А Мусиенко в 12 раз лучше, чем в группе традиционного лечения
Restoring voluntary control of locomotion after paralyzing spinal cord injury
No full textHalf of human spinal cord injuries lead to chronic paralysis. Here, we introduce an electrochemical neuroprosthesis and a robotic postural interface designed to encourage supraspinally mediated movements in rats with paralyzing lesions. Despite the interruption of direct supraspinal pathways, the cortex regained the capacity to transform contextual information into task-specific commands to execute refined locomotion. This recovery relied on the extensive remodeling of cortical projections, including the formation of brainstem and intraspinal relays that restored qualitative control over electrochemically enabled lumbosacral circuitries. Automated treadmill-restricted training, which did not engage cortical neurons, failed to promote translesional plasticity and recovery. By encouraging active participation under functional states, our training paradigm triggered a cortex-dependent recovery that may improve function after similar injuries in humans
FRAX-Based Intervention Thresholds for Osteoporosis Treatment in Ukraine
No full textObjectives. Osteoporosis, in addition to its consequent fracture burden, is a common and costly condition. FRAX® is a well-established, validated, web-based tool which calculates the 10-year probability of fragility fractures. A FRAX model for Ukraine has been available since 2016 but its output has not yet been translated into intervention thresholds for the treatment of osteoporosis in Ukraine; we aimed to address this unmet need in this analysis. Methods. In a referral population sample of 3790 Ukrainian women, 10-year probabilities of major osteoporotic fracture (MOF) and hip fracture separately were calculated using the Ukrainian FRAX model, with and without femoral neck bone mineral density (BMD). We used a similar approach to that first proposed by the UK National Osteoporosis Guideline Group, whereby treatment is indicated if the probability equals or exceeds that of a woman of the same age with a prior fracture. Results. The MOF intervention threshold in females (the age-specific 10-year fracture probability) increased with age from 5.5% at the age of 40 years to 11% at the age of 75 years where it plateaued and then decreased slightly at age 90 (10%). Lower and upper thresholds were also defined to determine the need for BMD, if not already measured; the approach targets BMD measurements to those at or near the intervention threshold. The proportion of the referral populations eligible for treatment, based on prior fracture or similar or greater probability, ranged from 44% to 69% depending on age. The prevalence of the previous fracture rose with age, as did the proportion eligible for treatment. In contrast, the requirement for BMD testing decreased with age. Conclusions. The present study describes the development and application of FRAX-based assessment guidelines in Ukraine. The thresholds can be used in the presence or absence of access to BMD and optimize the use of BMD where access is restricted
