Інноваційний інструментарій структурної політики управління розвитком аграрного сектору економіки
Authors: Kovalova O. V. 
Published: April 2020

Статтю присвячено дослідженню питань інноваційного інструментарію структурної політики управління розвитком аграрного сектору економіки.
Метою статті є дослідження та застосування інноваційних інструментів структурної політики управління розвитком аграрного сектору економіки.
Наукова новизна. Визначено, що існує взаємозв’язок між типом економічних відносин та моделлю управління, періодичністю процесів ускладнення та спрощення систем управління, пов’язаних із базовим розподілом праці. При спрощені (скороченні) функцій державного управління на перший план виходять альтернативні організації. Тому актуалізуються принципи належного врядування як елемент організаційно-управлінської системи політики, притаманний сучасним системам державного управління. Визначено логічні підсистеми структурної політики управління розвитком аграрного сектору економіки. Розроблено та обґрунтовано напрями і стратегічні пріоритети модернізаційної структурної політики в аграрному секторі економіки України.
Висновки. Забезпечення сталого розвитку аграрного сектору – визначальний пріоритет, який повинна враховувати держава при розробці і здійсненні структурної політики. Реалізація концепції сталого розвитку за рахунок раціонального використання потенціалу сільського сектору, сільського господарства й суміжних галузей має стати головною компонентою національного соціально-економічного зростання. Без відповідної структурної політики розвитку аграрного сектору рух в заданому напрямі є проблематичним. На такому баченні перспективи сьогодні наполягає усе передове світове співтовариство тому, що до аграрного сектору сформовані принципи економічної, екологічної та соціальної сталості. Усі вони пов’язані з природою та діяльністю людини, а сільське господарство – частина природи, яка задіяна у формуванні системи забезпечення головною компонентою людського існування – продовольством. Сталий розвиток аграрного сектору економіки нерозривно пов'язаний із забезпеченням сталого розвитку сільських територій. І тут необхідним є врахування зарубіжного, зокрема Європейського досвіду вирішення цієї проблеми. Вирішення даного питання вважаємо стратегічним для забезпечення конкурентоспроможного розвитку агропродовольчого комплексу та сільських територій. Стратегічні пріоритети сталого розвитку аграрного сектору економіки мають узгоджуватися з глобальними рішеннями, які прийняті світовою спільнотою, зокрема Цілями сталого розвитку 2030.

Abstract
Using selection criteria based on amplitude, time, and color, we have identified 329 objects as known or candidate cataclysmic variables (CVs) during the first year of testing and operation of the Zwicky Transient Facility. Of these, 90 are previously confirmed CVs, 218 are strong candidates based on the shape and color of their light curves obtained during 3–562 days of observation, and the remaining 21 are possible CVs but with too few data points to be listed as good candidates. Almost half of the strong candidates are within 10 deg of the galactic plane, in contrast to most other large surveys that have avoided crowded fields. The available Gaia parallaxes are consistent with sampling the low mass transfer CVs, as predicted by population models. Our follow-up spectra have confirmed Balmer/helium emission lines in 27 objects, with four showing high-excitation He ii emission, including candidates for an AM CVn, a polar, and an intermediate polar. Our results demonstrate that a complete survey of the Galactic plane is needed to accomplish an accurate determination of the number of CVs existing in the Milky Way.

COVID-19 has now become a pandemic. It has spread from Wuhan, China, in December 2019 to a large number of countries within three months. The objective of this work is to report the initial experience with epidemiologic and clinical features, as well as with the management of COVID-19 patients in India. This is a descriptive case series of the first 21 COVID-19 infected patients confirmed with polymerase chain reaction (PCR) and admitted to a tertiary care centre in India from 01.02.2020 to 19.03.2020. Clinical, laboratory, and radiologic data were collected, including age, sex, nationality, travel history, symptoms, duration of stay, and comorbidities. The mean age of the population was 40.3 years with a male preponderance. Thirteen (62%) patients had recent travel history outside India in the previous 30 days, two thirds of whom had travelled to Italy. The most common symptoms were fever and cough (42.9%) followed by sore throat, headache and breathlessness. Vital and laboratory parameters were preserved in all patients and none of them required ventilatory support. Among the first 21 patients diagnosed with COVID-19 infection in India, the typical clinical presentation consisted in a mild upper respiratory tract infection predominantly affecting the young male population. One patient required supplemental oxygen. All patients recovered with no residual symptoms.

Published: April 2020

Aim:
The study was designed to develop and standardize a novel polyherbal formulation (PHF) for augmenting milk production in healthy dairy cattle.

Materials and methods:
Five raw plant drugs, viz., tubers of Asparagus racemosus Willd. (Shatavari), whole plant of Eclipta alba (L.) Hassk. (Bhringraj), seeds of Trigonella foenum-graecum L. (Methika), fruits of Foeniculum vulgare Mill. (Mishreya.), and Anethum sowa Roxb. ex Fleming (Shatapushpa) were used to prepare hydroalcoholic extracts using the Soxhlet method. Three in-house batches of PHF were prepared and standardized as per Ayurvedic Pharmacopoeia of India (API) methods. Pharmacognostic authentication and chemical identification were done by macroscopic and microscopic studies, phytochemical screening, physicochemical analysis, and high performance thin layer chromatography (HPTLC) fingerprinting. The safety studies of galactagogue preparation were performed through heavy metals, microbial contamination, aflatoxins, and pesticide residue analysis.

Results:
Organoleptic studies revealed that all the batches appeared as semisolid in nature, blackish-brown in color, with a pleasant odor and slight bitter taste. Phytochemical screening confirmed the presence of similar secondary metabolites in the different batches of both raw drugs and PHF. Physicochemical analysis and HPTLC fingerprints at different illuminations showed that all three batches were uniformly composed and complied the pharmacopeial limits. Results of safety parameters advocated that all the three batches were safe and complied as per the WHO and API guidelines.

Conclusion:
The present work first claims the standardization of this unique, cost-effective, nonhormonal, Ayurvedic galactagogue in-house preparation, i.e., PHF for augmenting milk yield in dairy herd. It proves that all the three batches have similar characteristics and uniformly composed. It serves as a reference for identification and distinguishing the galactagogue herbs.
