Published: June 2022

Objetivos: Describir los resultados radiográficos, funcionales y las complicaciones de la cirugía percutánea en pacientes con fracturas de calcáneo tipo IIC de Sanders en lengüeta.
Materiales y Métodos: Se evaluaron 9 fracturas articulares de calcáneo desplazadas en 9 pacientes con radiografías de pie, de frente y de perfil, y tomografía computarizada preoperatorias. Se tomaron radiografías de pie, de frente y perfil, sin carga en el posoperatorio inmediato y con carga a las semanas 6 y 12, y al final del seguimiento. Se midió el ángulo de Böhler y se cuantificó el grado de artrosis subastragalina y calcaneocuboidea. Se evaluaron las siguientes variables: puntaje AOFAS, complicaciones de la herida, lesión neurológica y necesidad de cirugías adicionales, como retiro del material de osteosíntesis y artrodesis subtalar.
Resultados: El seguimiento fue de 21.1 meses. La edad promedio de los pacientes (3 mujeres y 6 hombres) era de 42 ± 12. El ángulo de Böhler preoperatorio fue de 7º (±6,2º) y de 33,6º (±4,1°) en el posoperatorio final (p <0,00001). Hubo una restricción leve de la movilidad subtalar en todos los pacientes. No se observó artrosis subtalar ni calcaneocuboidea. El puntaje AOFAS fue bueno en 4 pacientes y excelente en 5. Todos obtuvieron buenos y excelentes resultados. No se observaron infecciones de la herida, lesiones neurológicas ni complicaciones de la herida.
Conclusión: La cirugía percutánea en fracturas de calcáneo tipo IIC de Sanders en lengüeta permite lograr una reducción adecuada con buenos resultados funcionales y bajas tasas complicaciones de parte blandas.

В статті представлено результати досліджень по синтезу гідрогелевого матеріалу медичного призначення із використанням природніх біополімерів (альгінату натрію та желатину). Ці полімери є біосумісні, нетоксичні, біодеградабельні та відносяться до класу відновлюваної сировини. Комбіновані альгінат желатинові гідрогелі формуються внаслідок утворення сітки гідрогелю при сумісному перехресному зшиванні іонами кальцію макромолекул альгінату натрію, желатину та макроланцюгів рідкозшитої поліакрилової кислоти. Визначено оптимальні умови синтезу (мінімальні граничні межі концентрацій компонентів, мольне співвідношення йонів кальцію до кількості карбоксильних груп Са2+/СООН-) при яких комбіновані гідрогелі мають задовільні фізико-хімічні та механічні властивості. Залежності механічних властивостей альгінат-желатинові гідрогелі від ступеня набрякання вказують на широкий діапазон їх задовільних експлуатаційних характеристик. Вивчено здатність отриманих гідрогелів сорбувати та вивільняти знеболювальні препарати (лідокаїн та новокаїн). Здатність альгінат-желатинових гідрогелів до тривалого вивільнення лікарських препаратів дозволяє прогнозувати тривалість пролонгованої доставки цих препаратів до ран. Проведений аналіз цитотоксичності in vitro показав, що синтезовані гідрогелі не мають токсичного впливу на живі клітини. Сукупність переліченого спектру властивостей дозволяє стверджувати, що отримані комбіновані альгінат-желатинові гідрогелі є перспективним матеріалом для створення гідрогелевих пов’язок для догляду за ранами.

Published: June 2022

ABSTRAK Kemajuan ekonomi wilayah sangat ditentukan oleh perkembangan pusat pertumbuhan ekonomi. Kawasan Minapolitan Pasir Jambak sebagai lumbung penghasil produk perikanan tangkap di Kota Padang dapat menjadi salah satu pusat pertumbuhan ekonomi di Indonesia. Studi ini bertujuan untuk menganalisis kemampuan kawasan sebagai lumbung penghasil tangkapan yang optimal dan meningkatkan keberadaan cold storage (ruang pendingin) dalam menyerap hasil tangkapan nelayan lokal, menganalis langkah strategis dalam mengatasi kelangkaan produk dan menstabilkan harga di pasaran. Jenis penelitian ini adalah deskriptif kualitatif dengan menggunakan data primer dan data sekunder. Penelitian dilakukan pada Januari 2021. Pengumpulan data dilakukan melalui observasi, wawancara, dokumentasi dan FGD (Focus Group Disscusion). Teknik pemilihan responden menggunakan purposive sampling. Teknik analisis data dilakukan secara kualitatif dengan langkah reduksi data, penyajian data dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa kemampuan kawasan sebagai lumbung penghasil produk tangkapan laut belum mencapai optimal. Karena belum mampu memenuhi kebutuhan konsumsi lokal. Hasil tangkapan nelayan langsung diserap oleh pasar tanpa harus dibeli oleh pemilik cold storage. Pemilik cold storage justru membeli produk tangkapan nelayan yang berasal dari luar kawasan minapolitan. Dalam skala mikro cold storage sudah berperan dalam mengatasi kelangkaan produk di pasar dan bisa menstabilkan harga ketika terjadi kelangkaan komoditi. Perlu dilakukan pengembangan kawasan menjadi kawasan mandiri dengan meningkatkan volume hasil tangkapan nelayan, jenis komoditi yang dihasilkan dengan meremajakan armada kapal, meningkatkan kemampuan alat tangkap nelayan yang lebih moderen. Fasilitas penunjang suatu kawasan perikanan tangkap harus menjadi fokus pengembangan selanjutnya untuk menjadi kawasan yang maju dan berkembang. Kata kunci: kawasan minapolitan; hasil tangkapan; cold storage; kualitatif; armada kapal; alat tangkap

Published: June 2022

Purpose: the study of the current state of the potential level of digitalization of the sectors of the economy of the northern regions of the resource type (NRRT) and to identify possible promising directions for their development.Methods: the research is based on the application of standard methods of data collection and processing, comparative analysis and rating assessment. The data of the Federal State Statistics Service and statistical collections of the Higher School of Economics for the period 2010–2020 were used.Results: the rating of the TOP 10 countries of the world on digital competitiveness is presented. A methodological approach is proposed to substantiate the attribution of NRRT subjects to the resource-type category by calculating the share of the statistical indicator "mining" in the structure of the gross regional product. An assessment of the resource dependence of the regions of the Far North was carried out, based on the analysis of which the criteria for assigning eight subjects of the Russian Federation to NRRT were determined. The analysis and assessment of the current state of the level of digitalization of NRRT, which showed the leading positions of the Magadan region, Yamalo-Nenets and Khanty-Mansi Autonomous Okrugs, was carried out. It is noted that the level of regional expenditures on the introduction and use of digital technologies does not significantly affect the composite integral index of the digitalization potential of the northern resource–type regions.Conclusions and Relevance: the development of methodology and research on digitalization of resource regions of the Russian North, the results of which are presented in this article, is being implemented in a number of areas: the development of a conceptual scheme and a system of indicators for monitoring the northern regions; the development and construction of a composite index of development of the digital economy in the regions of the North; the development of methodology for monitoring the development and use of "end-toend" digital technologies (technologies for working with big data); monitoring and assessment of the level of development of the digital economy in the Arctic municipalities; the study of the relationship between socio-economic and digital development of the regions of the Russian North; the development of digital technologies of regional and municipal management and the study of socio-economic effects of their implementation; the study of digital transformation of priority economic sectors of the northern regions.
The global shortage of semiconductor components as a source of the current crisis in the global automotive industry
Authors: Shcherbakov G. A. 
Published: June 2022

Purpose: of this article is to identify the causes of the automotive industry crisis in 2020–2022, which led to the shutdown of the conveyor lines of the largest automotive companies around the world, based on the study of the degree of dependence of the automotive industry on microelectronic components.Methods: in preparing the work, a complex of scientific research methods was used, in particular, the method of system analysis, as well as conceptual-methodological and logical methods.Results: during the COVID-19 pandemic, the global automotive industry faced two unforeseen shocks that virtually paralyzed production output. The first of them was associated with a deep drop in demand for automotive products. The second – with the complete depletion of the semiconductor industry's production capacity for the release of critical microcircuits necessary for the production of cars. Both events, directly related to the change in consumer behavior during the pandemic, provoked a severe industry crisis, in which the automotive industry has been to this day. The resulting shortage showed the fragility of existing supply chains and the precariousness of the practice of "immediate production" in emergency economic conditions.Conclusions and Relevance: the crisis of the automotive industry in 2020–2021 proceeded in two stages and was triggered by two mutually exclusive reasons from the point of view of economic theory. The first stage is a drop in demand, a «classic» crisis of overproduction. The second stage of the crisis is a chronic (continuing for a long time) shortage of microelectronic components for automotive production. It is this phenomenon that does not fit into the framework of a generalized understanding of the functioning of market economy mechanisms.
Economic factors of increasing fertility in the Volga Federal District: a retrospective analysis (2000–2020)

Published: June 2022

Purpose: to determine the economic factors that steadily influenced reproductive trends in the Volga Federal District in 2000-2020, their regional differentiation. The hypothesis of the study: the dynamics of the birth rate is predetermined, among other things, by economic factors (of a general economic nature and economic activity of households). With a positive change in the economic well-being of the population and households, stable prerequisites are formed for the growth of the birth rate in the Volga Federal District.Methods: the correlation and regression analysis of the total fertility rate and economic predictors for 2000-2020 of the Volga Federal District regions was used. Econometric prerequisites for determining reproductive trends are formed based on changes in macro- and microeconomic indicators of the economic well-being of the region and individual households.Results: regional differences in the influence of economic factors on fertility are revealed: direct linear dependence on the volume of investments per capita and the level of employment; inverse dependence on the level of poverty and the share of household spending on food (except for the Republic of Bashkortostan). When assessing the inverse linear dependence on the indexation of prices for primary housing, the coefficient of determination is insufficient (except for the Udmurt Republic), as in the case of assessing the impact of the unemployment rate (the factor is insignificant for the Republic of Bashkortostan, Kirov Region, Perm Krai). The growth and decrease in monthly consumer spending lead to a decrease in the birth rate.Conclusions and Relevance: one-factor regression analysis showed that in the Volga Federal District, the formation of reproductive trends is negatively affected by an increase in the share of spending on essential goods. Multivariate regression analysis revealed a correlation of fertility rates with a steady increase in the level of employment. The presented approach can be used to describe the prerequisites for the formation of stable reproductive trends in other districts and regions of Russia for the implementation of preventive measures of the demographic policy of the state in order to maintain the stability and positive development of the demographic situation, prognostic estimates of trends of deviation from the positive trend.
Increasing the social responsibility of oil and gas companies in the context of the green economy formation: Russian and Western experience
Authors: Gusov A. Z. , Lylova E. V. , Kolganova E. V. , Eyeberdiyeva M. M. 
Published: June 2022

Purpose: the main idea of the article is to prove that the level of corporate social responsibility (hereafter CSR) of large gas and oil companies can be improved. This is a necessary condition for providing sustainable development of these companies because on the one hand the new paradigm of their development considers transition to low-carbon technologies, on the other hand, the main activity of gas and oil companies is associated with natural resources consumption, which inevitably leads to certain negative environmental consequences. At the same time, it is these consequences that trigger the process of establishing a green economy.Methods: the authors conducted a comparative and iterative analysis of the CSR development process of four major Western and four major Russian oil and gas companies.Results: large oil and gas companies around the world are deeply involved into the implementation of various areas of CSR in different directions to ensure long-term sustainable development. Our analysis showed that CSR areas are different and correspond to the basic set of CSR activities. Also, there are more advanced activities, though this applies only to individual companies. Oil companies have demonstrated certain features in their CSR practice, such as the variety of issues being addressed, the wide presence of intersectoral partnerships, and interaction with social entrepreneurs. However, not all companies are equally involved in the implementation of CSR.Conclusions and Relevance: the results of research allow us to determine the main reserves for improving the competitiveness of the analysed companies. The practical application of the results of this study is possible in the field of corporate governance, strategic planning for oil and gas companies. The results of the study are also of interest from the point of view of the development of scientific ideas about modern ways of implementing corporate social responsibility and the specifics of its implementation in the oil and gas industry.

Published: June 2022

Purpose: to identify objective patterns of development of mortgage–backed securities that determine the prospects of this direction to increase its role in the Russian economy.Methods: the study used general scientific methods of cognition, including comparative analysis, economic–statistical and abstract– logical methods, generalization and complex analysis. The methodological basis is the fundamental provisions of the theory of mortgages, the general theory of mortgage lending, thematic works of domestic and foreign scientists, as well as data from the Analytical Center DOM.RF.Results: the concept and classification of mortgage–backed securities are considered, the features of securitization are presented. The analysis of factors affecting the price level and profitability of mortgage–backed securities is carried out. The analysis of the state of the mortgage securities market in Russia has been carried out. The analysis of factors that have a significant impact on the current level of prices and yields of Russian mortgage bonds has been carried out. Development problems have been identified.Conclusions and Relevance: in the conditions of uncertainty in the Russian economy caused by the pandemic, sanctions, geopolitical tensions and inflation, retail investors are seek to secure their savings by investing them in bonds with yields higher than deposit rates. Bank deposits will remain the main way of saving money for the population. The popularity of bond investments will gradually grow, especially among the younger generation. The state has taken the right step towards improving the financial literacy of the Russian population and instilling a culture of investing in various instruments, especially securities. A similar practice should be applied to mortgage–backed securities. It is recommended to use positive experience in attracting individuals to certain segments of the stock market: simplification of access and purchase of mortgage bonds for the ordinary population; information campaign to popularize mortgage bonds as a simple investment tool with optimal compliance with the «risk–return» parameters; provision of state or institutional support measures in the form of tax benefits for investors, or reduced size agency commissions.
Psychometric Function Characteristics of Time- Compressed Persian Words
Authors: Moosapour Bardsiri Mohammadsaleh , Mahdavi Mohammad Ebrahim 
Published: June 2022

Background and Aim: The psychometric function characteristics (e.g. threshold and slope) of the time-compressed words have not been investigated in previous studies to compile psychometrically homogeneous word lists. Therefore, this study aimed to investigate psychometric function characteristics of monosyllabic time-compressed Persian words to develop psychometrically equivalent time-compressed word lists.
Methods: Two hundred most common monosyllabic words in Persian language were time- compressed at a rate of 40%-85% and presented to 21 participants with normal hearing at a fixed intensity level. The threshold and slope of the psychometric function for all words were determined using the logistic regression. The compression ratio (CR) for 5%-95% correct recognition was predicted based on the psychometric function fitted to the measured correct recognition score.
Results: Mean CR 50% of the words was in a range of 53%-78%. The mean CR 50% and slope were not significantly different between consonant-vowel-consonant and consonant- vowel-consonant-consonant words. The predicted CR for 5%-95% correct recognition varied from 61.5% to 88.4%. The final result was two 50-word lists of monosyllabic words with the same mean threshold and slope.
Conclusion: Persian time-compressed monosyllabic words have different CR 50% and slope that may interact with their intelligibility.

Keywords: Time compression; intelligibility; psychometric function; Persian monosyllabic words
