Increase of constant weight rates of weighing bottles and evaporating dishes in a pharmacological experiment
Authors: Chen Qun , Zhao Chenyu , Tan Chengbing , Arbad Ahmed
Published: October 2021

Improving the constant weight rates of weighing bottles and evaporation
dishes is beneficial to drug quality control. When different quantities of
weighing bottles were dried under the same conditions, the greater the
quantity is, the lower the constant weight rate will be. When quantities are
controlled to be the same, weighing bottles that have been cooled for 50
minutes have higher constant weight rates than those cooled for half an
hour. Without being affected by other factors, weighing bottles? constant
weight rates are higher when the bottles are dried at the temperature of 180?C than 105?C. The rate increases when the bottled are dried for 8 hours
instead of 5 hours. After soaking for 48 hours in the solution of 2% HNO3 +
6% HCl, the weighing bottles and evaporating dishes gain higher constant
weight rates. Being more efficient, faster, economical and practical, this
experiment has improved the method to increase constant weight rates of
weighing bottles and evaporating dishes, without the need of auxiliary
equipment, and thus increased the accuracy of drug weighing results.
Comprehensive correction method of airtight coring saturation based on core classification
Authors: Dong Junjie , Deng Rui
Published: October 2021

The indoor comprehensive analysis of core saturation of airtight coring wells
is an important part of well logging interpretation. According to the
saturation data, the geological reserves can be accurately calculated, and
the remaining oil saturation and water-flooded zone in the later stage of
the production well can be accurately evaluated. Due to the influence of
many factors in the coring process and the experiment process, the sum of
the core oil and water saturation is usually not equal to 100%. At present,
conventional airtight coring correction method is generally to analyze the
oil-water saturation, and then correct the data of the same factors that
affect the results. This article combines two methods for saturation
correction of XX oilfield in China. For cores with consistent missing
factors, mathematical statistics are used to correct the saturation. When
most of the rock pores have irreducible water and remaining oil, the phase
percolation split method is used for the correction after the experimental
analysis. By comparing with the logging interpretation results and the
results of adjacent wells, the feasibility of the comprehensive correction
method can be verified.

Authors: Zhang Yichi , Saito Shinichi , Tsuchiya Yoshishige , Wang Yeliang
Published: October 2021

A surface-modified scalable heat sink that can be fabricated by applying
silicon microfabrication technology has been proposed in this paper.
Theoretical estimation of the heat sink thermal resistance is based on the
heat sink with overall size of 1 cm ? 1 cm ? 1 cm, and four kinds of
structure with various total number of grooves on the surface of fins have
been investigated. Finite element analysis has been conducted by using
COMSOL Multiphysics where fluid dynamics and heat transfer are taken into
account. As a result, the lowest heat sinks thermal resistance of 6.84?C
per Watt is achieved for the structure with a larger fin area (13.1 cm2) and
a higher inlet air flow rate (4 m/s), suggesting an optimum fin area
depending on the air flow rate.
“near wall” combustion model of spark ignition engine
Authors: Wu Wenjing
Published: October 2021

This paper has illustrated a "near wall" combustion model for a spark
ignition engine that was included in a two-zone thermodynamic model. The
model has calculated cylinder pressure and temperature, composition, as well
as heat transfer of fresh and combustion gas. The CO submodel used a
simplified chemical equation to calculate the dynamics of CO during the
expansion phase. Subsequently, the HC submodel is introduced, and the
post-flame oxidation of un-burned hydrocarbon was affected by the
reaction/diffusion phenomenon. After burning 90% of the fuel, the
hydrocarbon reaction dominates at a very late stage of combustion. This
modeling method can more directly describe the ?near wall? flame reaction
and its contribution to the total heat release rate.
Comparison of the thermal focus shift and aberration between the single-mode and multimode lasers
Authors: Laskin Alexander , Volpp Joerg
Published: October 2021

Thermal lensing is a well-known but typically undesired effect during the use of laser optics. Nonuniform (gradient) heating due to absorption of high-power laser radiation in optical elements causes thermal lensing, paraxial focus shift, and aberration leading to changes in size and intensity profile of the focused spot in optics. Therefore, an analysis of primary physical effects of geometrical deformation of optical surfaces in the form of aspheric bulges and transformation of the material into a gradient refractive medium was conducted to quantitatively estimate the focus shift and aberrations. Since focus shift effects are different in the case of single-mode and multimode lasers, for both laser modes, the optimal relationships between the physical properties of optical materials for reduction in thermo-optical effects through compensating the material thermal expansion by the change in the refractive index—condition of self-compensation or athermalization were formulated. A comparison of the characteristics, namely, temperature coefficient of the optical pathlength and thermo-optical ratio allowed determination of the optimal materials for the optics for both single-mode and multimode high-power lasers: athermal crystalline quartz and specialty glasses, sapphire with extremely high thermal conductivity ensure minimal temperature gradients. Optics made of these materials exhibit a minimized thermal focus shift and aberration even during the absorption of laser energy in the bulk material and coatings by contamination, scratches, and other surface defects. Weak birefringence of crystalline quartz and sapphire does not prevent their successive use in laser optics.

Numerical Simulation for Interaction between the Fracture Surface and the Proppant Column after HiWay Fracturing
Authors: C Yong
Published: October 2021

HiWay fracturing uses impulse sand to achieve the proppant column supporting the rock wall surface, creating an open flow channel that is more conducive to improving the stimulation effect. The deformation law of the proppant column under the compression of the fracture wall surface is directly related to the effectiveness of the high conductivity fracture. However, the related laboratory physical simulation experiments are challenging to conduct, which restricts the study of the interaction between the fracture surface and the proppant column. In this paper, first, establish the finite element model of the interaction between the fracturing crack and the proppant column, and the variation law of stress-deformation of the crack wall and displacement of the crack wall under the closure stress is analyzed. Furthermore, this paper carries out the quantitative characterization of the active support area of the proppant column. Finally, the accuracy of the simulation results is verified by applying the experimental results of indoor proppant column rock plate compression. The numerical simulation method proposed in this paper can effectively realize the simulation of the interaction between the fracture surface and the proppant column in HiWay fracturing based on real engineering parameters, which lays theoretical and simulation experimental support for improving the effect of channel fracturing stimulation.
Petrophysical Signatures and Water-Reservoir Potential of Southern Apennines Turbiditic Sandstones Suites
Authors: S Critelli
Published: October 2021

After the seismic event of Irpinia (Southern Apennines), occurred on November 23rd 1980, the Pavoncelli tunnel, that used to supply with water the Puglia Region, was seriously damaged. Because of the strategic importance of this civil engineering work, a new water tunnel named Pavoncelli-bis that should substitute the previous one, was built and finally tested during the end of the 2019. The geological features of the area, highlighted the presence of three main siliciclastic formations (Corleto, pre-Numidian/Numidian and Castelvetere formations), crossed by the tunnel trace, that were petrophysically analyzed through the mercury injection porosimetry for a better definition of their petrophysical signatures and related water-reservoir potential at regional scale as hydrocarbon-reservoir potential. Data highlighted the presence of two clusters: one represented by the Corleto and Pre-Numidian Fms. showing good permeability (respectively 181.70 mD and 122.25 mD in median) and low porosity (respectively 4.56 % and 3.94 % in median); the other, represented by the Castelvetere Fm. highlighting good porosity (9.58 % in median) and a very low permeability (4.84 mD in median). Permeability, more than porosity, affects the cluster differentiation, whereas the other variables (average pore diameter and nanopores volume) do not show any particular trend. All these petrophysical parameters were compared with the sandstone composition (Qm, F, Lt), highlighting that porosity results negatively correlated to monocrystalline quartz (Qm) and positively correlated with feldspars (F). The lithic fragments values (Lt) are sparse and do not show any specific trend. The variability of porosity is directly linked with the diagenetic processes that interested the clusters of the Corleto and pre-Numidian Fms. (rich of Qm) and the Castelvetere Fm. (rich of F). Particularly, where quartz is more abundant, quartz cementation and overgrowth are more efficient and widespread, resulting in a reduction of the porosity. On the contrary, where feldspars are abundant, during diagenesis their dissolution can create new pore spaces and also clay-minerals with a better porosity than the previous feldspars. Moreover, clay-minerals can coat the quartz grains present in the sandstones inhibit the porosity loss of the quartz cementation and overgrowth. However, despite an increase in porosity, permeability decreases because the authigenic clays is mainly formed by isolated and blind pores.
Influence of Low Dosage Green Extracts on CO2 Hydrate Formation
Authors: PSR Prasad
Published: October 2021

Gas clathrates or the gas hydrates are the solid ice particles encapsulating gas molecules (commonly methane - CH 4 and carbon dioxide - CO 2 ) within the water cavities, at moderately high-pressure and low-temperature conditions. The petroleum extraction process from the deep-sea environment favours the occurrence of hydrates, and CO 2 hydrates require milder p, T conditions than CH 4 hydrates. Thus, chocking the pipeline network and obstructing the petroleum flow; leading to a substantial economic loss and hazardous. Conventional hydrate inhibitors (methanol, ethanol, glycols, Amino acids, and ionic liquids, etc.) are used, which are chemically toxic, costly, and required in large volumes (30-50 wt %). Therefore a suitable additive preventing plug formation is on high demand. The present study disclosures the use of three green leaf extracts Azadirachta indica (Neem - NL), Piper betel (betel - BL), and Nelumbo nucifera (Indian lotus - LL) in low dosage (0.5 wt %) on the CO 2 hydrate formation. Experiments are conducted in the isochoric method, with 0.5 wt % green-additives. The hydrates nucleate at higher subcooling (̴ 7-9 K), and the conversion is about ̴ 33-40 %. The induction time is nearly the same both pure- H 2 O and H2O with LL, whereas, it is ̴3 and 4 times higher for NL and BL. The hydrate growth kinetics also indicate significant retardation (2 – 4 times). Thus, these bio-additives, in low-dosage, could be an effective THI and also KHI for preventing the CO 2 hydrates plugs.

Published: October 2021

The COVID-19 pandemic has had a major impact on various sectors. Iran is one of the countries most affected by this pandemic. After considering the huge impact, the government imposed strict rules prohibiting social gatherings and restricting travel for the entire population following the large number of victims in the country. These restrictions lead to changes in the environment, especially air quality. The purpose of this study was to find out how the COVID-19 pandemic affected air quality in Iran following the activity restrictions in the region. The method used in this research was based on the use of multitemporal Sentinel-5P data processing with scripts available on the Google Earth Engine applied on the images, acquired in the period before and after the COVID-19 pandemic. The data used included the image collection of Sentinel-5P NRTI CO: Near Real-Time Carbon Monoxide, Sentinel-5P NRTI NO2: Near Real-Time Nitrogen Dioxide and Sentinel-5P NRTI SO2: Near Real-Time Sulphur Dioxide. The results showed, that for Iran in general, changes in the concentration of CO are clearly visible in urban areas with high population activity such as Tehran, where there was a decrease from 0.05 to 0.0286 mol/m2, while for other areas it is also influenced by the varying climate conditions, which affect the level of pollution. For the NO2 pollutant, there was a significant decrease in pollution levels in big cities such as Tehran, Qom, Isfahan and Mashhad from 0.0002 to 0.000114 mol/m2. For the SO2 pollutant, there was a decrease in pollution levels in Iran’s big cities from 0.0005 to 0.0000714 mol/m2. For Tehran province, which is the most populous and busiest province in Iran, it can be observed that there was also a decrease in the concentration of pollutants after the lockdown compared to the pre-lockdown period. The CO concentration decreased from 0.043 to 0.036 mol/m2, while for the NO2 pollutant there was a decrease from 0.0002 to 0.000142 mol/m2 and for the SO2 pollutant, there was a decrease from 0.0005 to 0.000143 mol/m2.

Study on the Mechanism of Hypertension Caused by Sorafenib in Liver Cancer-Bearing Rats Based on VEGF Signal Pathway
Authors:   People’s Hospital Of Huishan, Wang Kaicheng , Jiang Tingwang ,   The Affiliated Changshu Hospital Of Xuzhou Medical University
Published: October 2021

To explore the mechanism of hypertension caused by sorafenib in liver cancer-bearing rats based on Vascular Endothelial-Growth Factor (VEGF) signal pathway. After the three groups (blank, liver cancer and Spontaneously Hypertensive Rat (SHR) groups, n = 30) were administered orally with sorafenib (2 mg/kg), the non-invasive tail arterial pressure measurement was employed to determine the changes in blood pressure (BP). Enzyme-linked immunosorbent assay measured the changes of VEGF and Nitric Oxide (NO) in serum. The expressions of Kinase insert Domain Receptor tyrosine kinase (KDR-CD), endothelial Nitric Oxide Synthase (eNOS), Bax and Bcl-2 were detected by Western blot. TUNEL assay detected the Apoptosis Index (AI) of cardiomyocyte. CD31 immunohistochemical staining was observed the changes of Myocardial Capillary Density (MCD). The BP and VEGF levels of the blank and SHR groups were not significantly (P > 0.05) different from those in the before treatment cohort, while the BP of the liver cancer group was significantly (P < 0.05) higher. VEGF level was significantly (P < 0.05) lower than before. Compared with the blank group, the levels of NO, KDR-CD, eNOS, Bcl-2/Bax and MCD in the liver cancer group were significantly (P < 0.05) lower than those in the after administration, while the myocardial cell AI increased significantly (P < 0.05). After antagonist intervention, the BPs and myocardial AI of the liver cancer and SHR groups were significantly lower than before the intervention. Besides, levels of KDR-CD, eNOS, Bcl-2/Bax protein, MCD, serum VEGF and NO were significantly higher than before the intervention (P<0.05). Induction mechanism of hypertension induced by sorafenib may be owing to the inhibition of the VEGF signaling pathway, and reduction of endothelial cells proliferation leading to blockade of NO synthesis. This causes vasoconstriction, while promoting myocardial cell apoptosis and decreasing capillary density, thereby inducing the occurrence of hypertension.

Given different individual conditions, different TCM treatment strategies have been provided, such as moistening dryness and storing fluid, dispelling heat and detoxification, aroma penetrating filth and releasing lung and reducing turbidity.. To provide some references to the treatment of COVID-19 and related diseases and to lay a certain foundation for subsequent new drug research, this paper generalized the application and potential mechanisms of TCM in the prevention and treatment of COVID-19.
A Famous Chinese Prescription That Promotes Hcn4 Activity in Bone Marrow Mesenchymal Stem Cells is Shenfu Injection: Opinion
Authors:   The First Affiliated Hospital Of Guangzhou University Of Chinese Medicine, Li Rong
Published: October 2021

Sick Sinus Syndrome (SSS) refers to a group of heart rhythm disorders caused by problems relating to the sinus node. Currently, there is no effective treatment for SSS, and an electronic pacemaker is required to support heart function in SSS patients. However, electronic pacemakers are associated with several defects. For example, external magnetic noise commonly interferes, leading to complications. In addition, some patients, especially children with congenitals inoatrial node dysfunction, are not suitable subjects for pacemaker insertion. Therefore, the search for new therapeutic strategies for treating cardiovascular diseases has become imperative. Shenfu injection (SFI), a Chinese herbal medicine, is effective in improving bradyarrhythmia. However, the underlying mechanism of SFI's therapeutic effect remains elusive.

The Implementation of Bill 212 in Ontario Schools: Implications for Black Students
Authors: Gateri Hellen , Richards Donna
Published: October 2021

In February 2008, Bill 212 (Progressive Discipline and School Safety) replaced Bill 81, the Safe Schools Act of June 2000 with regards to the behaviour, discipline, and safety of students. However, since Bill 212 has been in effect, suspensions and expulsions have been unfairly implemented against Black secondary students. Using anti-Black racism (ABR) framework, this commentary paper explores the effects of sections 306–311 of the Bill on Black students within Ontario's secondary school system. Based on this exploration, we will critically examine the way suspensions and expulsions have been employed through Bill 212 and the consequences of these disciplinary measures for Black students. We recommend alternative practices such as restorative justice and the integration of ABR framework to address students’ inappropriate behaviours in the educational system.

Authors: ARI Yakup
Published: October 2021

The importance of the health sector is once again understood by the emergence of the Covid-19 pandemic. The purpose of this study is to examine the volatility spillover effect between health sector stocks traded in Istanbul Stock Exchange and exchange rate and precious metal prices during the pre-Covid-19 period and the Covid-19 period. For this purpose, the volatility of returns of four health sector stocks traded on the Istanbul Stock Exchange, foreign exchange rate, and the price of gold were obtained using the Exponential Weighted Moving Average model and used in the Diebold-Yılmaz Spillover Index approach. The data set is divided into two periods according to the date of the first cases seen in Turkey. While the first period consisted of 267 observations between January 2, 2019, and February 28, 2020, the second period consisting of 267 observations was created between March 2, 2020, and April 1, 2021. According to the results, the total spillover index in the period before Covid-19 is 9.60%, which indicates a low connectedness between markets. The spillover index for the Covid-19 period is calculated at 21.90% which means the error variances in markets are on average 21.90% originated from other markets. Moreover, it is found that RTA Laboratories has the highest net spillover in the Covid-19 period.
Interplay between MPIase, YidC, and PMF during Sec-independent insertion of membrane proteins
Authors: Endo Yuta , Shimizu Yuko , Nishikawa Hanako , Sawasato Katsuhiro , Nishiyama Ken-ichi
Published: October 2021

Integral membrane proteins with the N-out topology are inserted into membranes usually in YidC- and PMF-dependent manners. The molecular basis of the various dependencies on insertion factors is not fully understood. A model protein, Pf3-Lep, is inserted independently of both YidC and PMF, whereas the V15D mutant requires both YidC and PMF in vivo. We analyzed the mechanisms that determine the insertion factor dependency in vitro. Glycolipid MPIase was required for insertion of both proteins because MPIase depletion caused a significant defect in insertion. On the other hand, YidC depletion and PMF dissipation had no effects on Pf3-Lep insertion, whereas V15D insertion was reduced. We reconstituted (proteo)liposomes containing MPIase, YidC, and/or F0F1-ATPase. MPIase was essential for insertion of both proteins. YidC and PMF stimulated Pf3-Lep insertion as the synthesis level increased. V15D insertion was stimulated by both YidC and PMF irrespective of the synthesis level. These results indicate that charges in the N-terminal region and the synthesis level are the determinants of YidC and PMF dependencies with the interplay between MPIase, YidC, and PMF.

В связи с этим в данной работе были систематизированы факторы (социально-экономические, внешнеэкономические, структурные, факторы, связанные с доверием населения и неопределенностью и др.) и критерии (количественные и качественные), способствующие формированию и эффективной реализации денежно-кредитной политики ЦБ. Проведенный анализ показал, что необходим гибкий подход, сочетая как математический, так и теоретический инструментарий в условиях нестабильности экономики. Автором выделены мероприятия, реализация которых позволит менять текущую политику. Также выявлены некоторые аспекты, представляющие определенный вызов эффективной реализации ДКП (достижение умеренной инфляции, минимизация влияния на конъюнктуру внутреннего валютного рынка со стороны ЦБ, снижение зависимости курса рубля от цен на энергоресурсы, снижение уровня долларизации российской экономики и др). Область применения результатов. Результаты проведенного исследования могут быть использованы при анализе и прогнозировании структурных изменений в денежно-кредитной политике ЦБ. Выводы. Делается вывод, что комплексный подход, включающий в себя бюджетно-налоговые и денежно-кредитные инструменты, может способствовать не только стабилизации банковской системы в стране, но и достижению нового уровня экономического развития.

Цель работы. В статье исследованы тенденции развития мировой экономики в условиях пандемии коронавируса 2020 года. Метод или методология проведения работы. Проведены анализ и обобщение результатов развития стран мира в условиях влияния пандемии на экономику. Результаты. Выявлены основные тенденции, определяющие развитие мировой экономики на ближайшую перспективу. К ним следует отнести: сокращение мирового ВВП; снижение экономической активности, доходов на душу населения; деглобализацию и нарушение цепочки поставок; рост цифровой экономики, «экзабайтной экономики», круговой экономики, «экономики впечатлений», новых инвестиционных моделей и рынков; глобальное неравенство; изменение структуры потребления и сопутствующие этому процессы; экономическое соперничество стран. Область применения результатов. Результаты проведенного исследования могут быть использованы при анализе и прогнозировании тенденций развития стран мировой экономики. Выводы. Сделан вывод, что кризис, вызванный пандемией COVID-19, не похож ни на какой другой, а его последствия все еще непредсказуемы, следовательно, перспективы экономического восстановления также остаются неопределенными. Критически важной является необходимость сотрудничества всех стран и их коллективных действий для смягчения последствий кризиса, защиты уязвимых слоев населения и усиления способности стран справляться с подобными событиями в будущем.
НАПРАВЛЕНИЯ ЭКСТЕНСИВНОГО РАЗВИТИЯ ТРАНСПОРТНОЙ инфраструктуры города
Authors: Параскевов Александр Владимирович
Published: October 2021

Цель работы. В статье рассматривается ситуация, сложившаяся в транспортной инфраструктуре современных городов. Метод проведения работы. Проведен анализ современного состояния уличной дорожной сети. Результаты. Города, как правило, застраивались стихийно, не системно, во время строительства дорог не было расчета на нынешнее количество автотранспорта. В настоящее время заторы на дорогах – проблема больших городов. Развитие города может идти двумя способами – экстенсивным и интенсивным. Интенсивное предполагает качественное переосмысление необходимых работ, оптимизацию и совершенствование на основе уже существующей инфраструктуры. Предложена методика экстенсивного развития городской уличной дорожной сети, а также комплекс мер по преодолению транспортных коллапсов. Практическая значимость проведенного исследования состоит в возможности непосредственного использования усовершенствованных методик, алгоритмов, архитектур и программного комплекса для функционирования в составе системы управления городским дорожным движением. При этом методика позволяет увеличить плавность движения транспортных потоков на всем протяжении уличной дорожной сети, а также получать дополнительные финансовые потоки для текущего ремонта и совершенствования элементов уличной дорожной сети. Реализация результатов моделирования введения платы за проезд будет удалять все очереди, образовавшиеся из-за переполнения транспортной сети. Это должно произойти благодаря замене простоя в пробке эквивалентным размером платы за проезд. Область применения результатов. Результаты проведенного исследования могут быть использованы при системном изменении транспортной инфраструктуры города, планировании новых микрорайонов. Выводы. Пути преодоления транспортных коллапсов лежат в поле экстенсивного развития, грамотного планирования и транспортной политики.
ГОСУДАРСТВЕННАЯ ПОЛИТИКА ИМПОРТОЗАМЕЩЕНИЯ: ОЦЕНКА РЕГИОНАЛЬНЫХ ЭФФЕКТОВ (НА ПРИМЕРЕ ДАЛЬНЕВОСТОЧНОГО ФЕДЕРАЛЬНОГО ОКРУГА)
Authors: Белоусова Анна Васильевна
Published: October 2021

Цель работы. Целью настоящей работы является получение оценок экономических эффектов государственной политики импортозамещения для отдельного региона (единицы административно-территориального деления РФ). Метод или методология работы. Основным методом исследования выступает балансовое структурное моделирование, основанное на принципах методологии национального счетоводства. Результаты. Для случая Дальневосточного федерального округа разработана и статистически наполнена матрица финансовых потоков; проведена ее балансировка. Матричная конструкция является симметрической и содержит 9 счетов: производственный сектор (счета товаров и услуг, видов экономической деятельности), сектор факторов производства (счета капитала и труда), сектор институциональных единиц (счета предприятий, домашних хозяйств, правительства, остального мира), сектор капитала (одноименный счет). На основе структуры расходов по каждому из счетов получены оценки изменений финансовых потоков в экономической системе, обусловленные уменьшением объемов импортной продукции в товарном балансе Дальневосточного макрорегиона. Количественно идентифицированы мультипликативные эффекты, генерируемые экзогенным увеличением спроса, без и с учетом результатов государственной политики импортозамещения. Область применения результатов. Результаты проведенного исследования могут быть использованы при формировании мер государственной политики, направленной на снижение рисков от внешнеторговой деятельности, обеспечение условий региональной экономической безопасности. Дезагрегация объекта исследования позволит провести сравнительный анализ эффектов импортозамещения в пространственном разрезе. Соотнесение полученных оценок с затратами бюджетных средств, необходимых для уменьшения доли импортной продукции в товарном балансе, позволит определить потенциальные «выгоды» и/или «убытки» проводимой государством политики. Использование оценок матричных мультипликаторов позволяет прогнозировать реакции дальневосточной экономики на действие экзогенных факторов. Выводы. Путем количественного анализа мультипликаторов матрицы финансовых потоков доказано, что реализация политики импортозамещения увеличивает положительные эффекты для экономики Дальневосточного федерального округа.

Цель работы. Целью исследования является анализ показателей сферы здравоохранения регионов Приволжского федерального округа в динамике с 2013 г. Анализ включает себя показатели смертности, заболеваемости, инвалидизации, профилактики здоровья, финансовых, инфраструктурных и кадровых ресурсов системы здравоохранения как, с одной стороны, совокупности институтов и ресурсов, цель которых – улучшение здоровья населения, и, с другой стороны, как инструмента, с помощью которого государство как гарант охраны здоровья и оказания доступной и качественной медицинской помощи реализует свои задачи. Метод или методология проведения работы. Основным методом исследования является сравнительный анализ. Результаты. В процессе анализа выявлены положительные и негативные тенденции в сфере здравоохранения и общественного здоровья в рассматриваемых регионах. Регионами-лидерами оказались Нижегородская область и Республика Татарстан, наиболее отстающие результаты зафиксированы у Республики Марий Эл. В целом можно констатировать, что значения показателей регионов ПФО по сравнению со среднероссийскими значениями имеют положительные показатели и динамику показателей в сфере здравоохранения. Область применения результатов. Результаты исследования могут быть применены на практике органами региональной власти, отвечающими за функционирование и стратегическое развитие сферы здравоохранения, а также курирующих реализацию национальных проектов «Здравоохранение» и «Демография». Выводы. В целом многие рассмотренные количественные значения регионов ПФО по сравнению со среднероссийскими значениями имеют положительную динамику показателей в сфере здравоохранения, но это ни в коем случае не констатирует, что нет необходимости усовершенствовать работу региональных систем здравоохранения и улучшать показатели общественного здоровья, ведь это, помимо решения социальных проблем, способствуют ускорению экономического развития региона. Пандемия COVID-2019 должна стать для современности ярким примером ценностного отношения к вопросам здоровья как индивида, так и системы здравоохранения в целом.
АНАЛИЗ ПРОБЛЕМ РАЗВИТИЯ ПРЕДПРИНИМАТЕЛЬСТВА КАК ДОПОЛНИТЕЛЬНОГО РЕСУРСА ИННОВАЦИОННОГО РАЗВИТИЯ РЕГИОНА (НА ПРИМЕРЕ РЕСПУБЛИКИ ДАГЕСТАН)
Authors: Стофарандова Виктория Васильевна
Published: October 2021

Цель работы. На основе анализа механизмов перехода социально-экономической деятельности на инновационный путь развития описать проблемы развития предпринимательства как дополнительного ресурса инновационного развития региона. Метод или методология проведения работы. Теоретико-методологические изыскания с применением логических и эмпирических методов исследования позволили рекомендовать принятие решений о формировании государственной и региональной инновационной политики. Результаты. Развитие малого и среднего бизнеса выступает одним из главных факторов социальной и политической стабильности в регионе. Но несмотря на это данный бизнес не ощущает существенной государственной поддержки. А хорошо было бы увеличить вклад малого и среднего бизнеса в ВВП региона и государства. Область применения результатов. Результаты проведенного исследования могут быть использованы органами власти и управления, в том числе регионов, при прогнозировании инновационного развития территорий и определении наиболее перспективных направлений, обеспечивающих значительный социально-экономический рост региона. Выводы. Одним из факторов социальной стабильности в регионе выступает малый и средний бизнес. В регионе должна быть выработана определенная концепция и стратегия поддержки малого и среднего бизнеса и определены ее основные направления. Кроме того, необходимо заинтересовывать частных инвесторов в финансировании предприятий малого бизнеса. Потому что государство на сегодняшний день слабо справляется с такой нагрузкой.
