The evolution and experience of China’s rural governance reform
Authors: Stoyanets Nataliia , Hu Zetao , Chen Junmin
Published: January 2023

Purpose. The purpose of this paper is to review the evolutionary development process of rural governance in New China and to reflect on the governance measures adopted by the country's rural revitalization strategy.

Methodology / approach. This paper uses theoretical analysis and comparative analysis methods to analyze the rural governance practices since the founding of New China by using the perspective of endogenous development theory. Through the literature research and related policy documents of a large number of rural governance researches, the paper summarizes the accumulated data, analyzes the evolution process of rural governance in China and evaluates the current status of the governance system.

Results. The article briefly reviews the evolution of rural governance in China since the founding of New China, including major policy adjustments and changes in actual conditions. Domestic scholars have studied the ability of each subject to participate in governance and the actual governance model. It should be pointed out that the importance of participating ability in the subject is more significant when various conditions are becoming more and more perfect. Especially in the case of the country’s continuous strengthening of the external governance capacity at the grassroots level, the villagers’ own participation ability and willingness have not improved, so the purpose of governance itself is difficult to achieve. It may further affect the realization of the national rural revitalization strategy and the governance modernization process of the entire country.

Originality / scientific novelty. From the perspective of endogenous development, this paper analyzes the ability of rural governance to participate in the main body, and evaluates the problems faced by rural governance in the current stage of China’s injection of huge resources into rural areas.

Practical value / implications. To better play a role in the current rural revitalization strategy, the government provides a way of thinking to better formulate policies and achieve sustainable development in rural areas.

Authors: Yang Chen , Lukash Svitlana , Ran Guo Qing
Published: January 2023

Purpose. Based on the econometric model (Kuznets curve) of the relationship between economic growth and environmental pollution – Environmental Kuznets Curve, this article analyses the relationship between economic growth and environmental pollution in Henan Province, and studies the natural economic relationship.

Methodology / approach. Three kinds of regional pollution index data of waste gas pollution and solid waste pollution and relative data of per capita GDP in Henan province were analyzed by using STATA software and OLS method was used to fit the relationship between environmental quality and economic growth, and the regression curve with the best fitting degree was obtained.

Results. This article analyses the relationship between the overall environmental quality and economic growth in Henan Province over the years. According to the established data model it is obviously that economic growth itself cannot promote the improvement of environmental quality. To realize the double goals of economic growth and environmental protection, the key is to find out the inherent law of economic change in the process of economic growth, so as to construct a long-term mechanism of promoting environmental friendly economic growth. It is necessary: strengthening of pollution control and reduce pollutant discharge; follow the economic road of recycling resources; optimizing industrial structure and promoting coordinated sustainable development; adhere to the policy of energy saving and emission reduction.

Originality / scientific novelty. Author’s developed econometric model is very useful in empirical assessment for the sustainable development of resources, environment and economy in Henan Province, and to provide a decision-making reference for the development of ecological environment in Henan Province. Accordingly, the proposed method, in the face of high-speed economic development today, put forward the countermeasures of economic sustainable development.

Practical value / implications. Using the author’s proposed method leads to the achievement of the following results: can better promote Henan Province economy and ecological environment coordinated development.

Структура прямого и сопутствующего эффекта роста объемов товарной продукции на пищевых предприятиях
Authors: Parmacli Dmitrii , Soroka Larisa
Published: January 2023

Цель. Цель исследования – обосновать и показать на конкретном примере методику расчетов прямого и сопутствующего эффекта прироста объемов реализованной продукции и на этой основе обеспечить преподавателей и студентов высших учебных заведений, а также специалистов отрасли современным методическим инструментарием.

Методология / методика / поход. При проведении данного исследования использованы общенаучные и специальные методы, а именно: абстрактно-логический – для обоснования методики расчетов величины прибыли в расчете на единицу продукции, метод экономического сравнения – при сравнении базового и расчетного вариантов, а также графический метод – при выявлении тенденций изменения показателей реализованной продукции.

Результаты. Исследование структуры экономического эффекта, вызванного увеличением объемов реализации товарной продукции, имеет свои особенности. Внедрение новых организационно-экономических мероприятий приводит не только к прямому экономическому, но и существенному сопутствующему эффекту. Приводятся особенности расчетов экономической эффективности инновационных разработок на пищевых предприятиях. В частности, представлена методика исчисления размера прибыли в расчете на единицу товара и всего по предприятию, в том числе за счет роста объема реализованной продукции, снижения себестоимости и повышения цен на товары. Вполне очевидно, что по мере роста объемов реализации увеличивается размер прибыли. Однако здесь выявлена следующая закономерность: прирост прибыли за счет снижения себестоимости продукции, как правило, выше прироста прибыли от увеличения объема товаров. Данная зависимость подтверждена на конкретном примере предприятия по производству пива.

Оригинальность / научная новизна. Проведенные исследования показали, что эффективность внедрения инновационных разработок на предприятиях, направленных на повышение объемов товарной продукции, зависят не только от размеров прироста объемов реализации, снижения их себестоимости и роста цен, но и от исходного состояния производства, выраженного в соотношении постоянных и переменных затрат и сложившегося уровня рентабельности продукции. Превышение эффекта, вызванного снижением себестоимости продукции, над эффектом роста объемов реализованного товара обеспечивает та инновационная разработка, которая при прочих условиях внедряется на предприятиях, имеющих более высокие показатели доли постоянных затрат, а рентабельность продукции ниже. Полученные результаты исследования выполнены авторами впервые на примере деятельности конкретного предприятия пищевой отрасли.

Практическая ценность / значимость. Выше изложенное позволяет утверждать, что экономическая оценка структуры прямого и сопутствующего эффекта роста объемов реализации продукции на пищевых предприятиях отличается простотой применения и потому окажется достаточно востребованной как в учебных целях, так и в реальных производственных условиях.
Analysis of expenditure path beyond staple foods consumption in Nigeria
Authors: Ikudayisi Adesola , Omotola Aderonke
Published: January 2023

Purpose. This study investigates the food expenditure path segmented by staples and non-staples in Nigeria.

Methodology / approach. A multi-stage sampling procedure was used to sample a cross sectional data of 438 urban households from two randomly selected urbanising states in South West, Nigeria. The study used descriptive statistics such as percentages and means to determine households’ food budget shares and their per capita food expenditure

Results. From the expenditure estimates, a differential effect in budget share of food was found with an increase in staples diet of Low Urban Area (LUA) households (33 %). However, consumption of non-staple foods was more pronounced among households residing in high urban areas (HUA) (35 %). Per capita food expenditure was higher for LUA households (N1377.52), while their food shares for processed cereals were equal with those of HUA. Findings suggest a more diverse diets, thus revealing a quality-quantity nexus within urban locations.

Originality / scientific novelty. This is the very study that explains urban differential beyond staple food consumption and nutritional outcome. The household food expenditure pattern brought to fore location-specific variations in urban diet in the study area.

Practical value / implications. The switch away from consumption of staples was beyond income responsiveness, but, towards changes in level of urbanization. The differential path in per capita expenditures on staple and non-staples are shown to have implications on nutrition within urban areas.

This study aims to analyze the epistemology of "Al-Quran and the Banyumasan Javanese Translation" (hereinafter abbreviated as QTJB) compiled by 10 translators with different scientific backgrounds. This research is qualitative research which aims to: 1) determine the background of the compilation of "Al-Quran and the Javanese Banyumasan Translation" and a description of the social space when the translation is compiled; 2) knowing the source and method of translation; and 3) knowing the contribution of the translation of the Al-Quran in the Javanese Banyumas language in preserving local languages, especially the Javanese Banyumas language. This study found that the QTJB manuscript uses the ḥarfiyyah translation method as well as the ṭafsīriyyah method armed with the Koran and its translation (QTK) published by the Ministry of Religion as the main reference and several classical commentaries and the Banyumas-Indonesian dialect dictionary. The results of translating the Koran into the Javanese Banyumasan language in the form of the QTJB manuscripts did not add new vocabulary to the Banyumas Javanese vocabulary, but QTJB took another form in the preservation of the Banyumas Javanese language by reintroducing vocabulary. forgotten words and almost wiped out from the vocabulary of today's society.
Microphysical, macrophysical, and radiative responses of subtropical marine clouds to aerosol injections
Authors: Chun Je-Yun , Wood Robert , Blossey Peter , Doherty Sarah J.
Published: January 2023

Abstract. Ship tracks in subtropical marine low clouds are simulated and investigated using large-eddy simulations. Five variants of a shallow subtropical stratocumulus-topped marine boundary layer (MBL) are chosen to span a range of background aerosol concentrations and variations in free-tropospheric moisture. Idealized time-invariant meteorological forcings and approximately steady-state aerosol concentrations constitute the background conditions. We investigate processes controlling cloud microphysical, macrophysical, and radiative responses to aerosol injections. For the analysis, we use novel methods to decompose the liquid water path (LWP) adjustment into changes in cloud and boundary-layer properties and to decompose the cloud radiative effect (CRE) into contributions from cloud macro- and microphysics. The key results are that (a) the cloud-top entrainment rate increases in all cases, with stronger increases for thicker than thinner clouds; (b) the drying and warming induced by increased entrainment is offset to differing degrees by corresponding responses in surface fluxes, precipitation, and radiation; (c) MBL turbulence responds to changes caused by the aerosol perturbation, and this significantly affects cloud macrophysics; (d) across 2 d of simulation, clouds were brightened in all cases. In a pristine MBL, significant drizzle suppression by aerosol injections results not only in greater water retention but also in turbulence intensification, leading to a significant increase in cloud amount. In this case, Twomey brightening is strongly augmented by an increase in cloud thickness and cover. In addition, a reduction in the loss of aerosol through coalescence scavenging more than offsets the entrainment dilution. This interplay precludes estimation of the lifetime of the aerosol perturbation. The combined responses of cloud macro- and microphysics lead to 10–100 times more effective cloud brightening in these cases relative to those in the non-precipitating MBL cases. In moderate and polluted MBLs, entrainment enhancement makes the boundary layer drier, warmer, and more stratified, leading to a decrease in cloud thickness. This LWP response offsets the greatest fraction of the Twomey brightening in a moderately moist free troposphere. This finding differs from previous studies that found larger offsets in a drier free troposphere, and it results from a greater entrainment enhancement of initially thicker clouds, so the offsetting effects are weaker. The injected aerosol lifetime in cases with polluted MBLs is estimated to be 2–3 d, which is much longer than estimates of typical ship track lifetimes from satellite images.
stoPET v1.0: a stochastic potential evapotranspiration generator for simulation of climate change impacts

Published: January 2023

Abstract. Potential evapotranspiration (PET) represents the evaporative demand in the atmosphere for the removal of water from the land and is an essential variable for understanding and modelling land–atmosphere interactions. Weather generators are often used to generate stochastic rainfall time series; however, no such model exists for the generation of a stochastically plausible PET time series. Here we develop a stochastic PET generator, stoPET, by leveraging a recently published global dataset of hourly PET at 0.1∘ resolution (hPET). stoPET is designed to simulate realistic time series of PET that capture the diurnal and seasonal variability in hPET and to support the simulation of various scenarios of climate change. The parsimonious model is based on a sine function fitted to the monthly average diurnal cycle of hPET, producing parameters that are then used to generate any number of synthetic series of randomised hourly PET for a specific climate scenario at any point of the global land surface between 55∘ N and 55∘ S. In addition to supporting a stochastic analysis of historical PET, stoPET also incorporates three methods to account for potential future changes in atmospheric evaporative demand to rising global temperature. These include (1) a user-defined percentage increase in annual PET, (2) a step change in PET based on a unit increase in temperature, and (3) the extrapolation of the historical trend in hPET into the future. We evaluated stoPET at a regional scale and at 12 locations spanning arid and humid climatic regions around the globe. stoPET generates PET distributions that are statistically similar to hPET and an independent PET dataset from CRU, thereby capturing their diurnal/seasonal dynamics, indicating that stoPET produces physically plausible diurnal and seasonal PET variability. We provide examples of how stoPET can generate large ensembles of PET for future climate scenario analysis in sectors like agriculture and water resources with minimal computational demand.
Origin of low-tropospheric potential vorticity in Mediterranean cyclones
Authors: Scherrmann Alexander , Wernli Heini , Flaounas Emmanouil
Published: January 2023

Abstract. Mediterranean cyclones are extratropical cyclones, typically of smaller size and weaker intensity than other cyclones that develop over the main open ocean storm tracks. Nevertheless, Mediterranean cyclones can attain high intensities, even comparable to the ones of tropical cyclones, and thus cause large socioeconomic impacts in the densely populated coasts of the region. After cyclogenesis takes place, a large variety of processes are involved in the cyclone’s development, contributing with positive and negative potential vorticity (PV) changes to the lower-tropospheric PV anomalies in the cyclone center. Although the diabatic processes that produce these PV anomalies in Mediterranean cyclones are known, it is still an open question whether they occur locally within the cyclone itself or remotely in the environment (e.g., near high orography) with a subsequent transport of high-PV air into the cyclone center. This study introduces a Lagrangian method to determine the origin of the lower-tropospheric PV anomaly, which is applied climatologically to ERA5 reanalysis and to 12 monthly simulations, performed with the integrated forecasting system (IFS) model. We define and quantify so-called “cyclonic” and “environmental” PV and find that the main part of the lower-tropospheric PV anomaly (60 %) is produced within the cyclone, shortly prior (−12 h) to the cyclones' mature stage. Nevertheless, in 19.5 % of the cyclones the environmental PV production near the mountains surrounding the Mediterranean Basin plays a significant role in forming the low-tropospheric PV anomaly and therefore in determining the intensity of these cyclones. The analysis of PV tendencies from the IFS simulations reveals that the major PV production inside the cyclone is typically due to convection and microphysics, whereas convection and turbulent momentum tendencies cause most of the positive PV changes in the environment.
Organismos Constitucionales Autónomos y rendición de cuentas horizontal en México: 1990-2020
Authors: Torres Fragoso Jaime
Published: January 2023

El objetivo de esta investigación es describir el estado que presenta la rendición de cuentas horizontal y analizar la calidad de la democracia en México. Además de una revisión documental, para ese fin se emplearon las bases de datos de V-Dem en lo que corresponde a dos indicadores: Control del Ejecutivo e Índice de Democracia Liberal. Los resultados muestran el regreso del viejo presidencialismo mexicano, un desempeño decepcionante de este país en ambos índices y, lo más preocupante, en declive. Entre las conclusiones se advierte que, debido a ello, no se puede afirmar que en México existe un verdadero Estado de derecho, una cabal separación de poderes y una democracia plena.
La batalla virtual por la memoria: Un análisis de las memorias en disputa en Twitter durante la Marcha del Silencio del 2020 en Uruguay
Authors: Acosta y Lara Borba Federico , Wilchinski Hirschfeld Marcelo
Published: January 2023

El estado de emergencia sanitaria decretado por la pandemia de COVID-19 obligó a que la Marcha del Silencio, una de las marchas tradicionales más multitudinarias del Uruguay, se trasladase por completo al ámbito virtual. En este inédito contexto, el presente artículo innova en el campo de los estudios de memoria pública al utilizar un análisis cuantitativo de la actividad en Twitter para analizar la batalla de memorias sobre el pasado reciente uruguayo. En línea con la literatura existente, se prueba la existencia de al menos dos memorias confrontadas, una predominante, que tiene al terrorismo de Estado como su concepto principal y con fuertes vínculos con la izquierda política, y otra memoria alternativa, que se articula según la ‘teoría de los dos demonios’. Para cada una de estas memorias se caracterizan los actores más relevantes y sus vínculos incluyendo la participación de los partidos políticos, legisladores y ministros.

Em “A bordo dos dias” propomos, a partir de nossas anotações, croquis, registros fotográficos e videográficos, compor um artigo como um diário de bordo dialógico, escrito coletivamente. Nesta relação da viagem realizada com a escrita e as poéticas contemporâneas surgem aproximações entre muro/fronteira, estrangeiro/residente, hospitalidade/hostilidade, território/poder, espaço público/privado, Norte/Sul, experiência/relato. Assim, esse caderno nômade que tradicionalmente acompanha viagens, torna-se, para artistas viajantes, uma reflexão teórica, poética, e uma maneira de responder à pergunta de Baudelaire: “diga, o que você viu?”. O diário de bordo é também a viagem.

Published: January 2023

The process of taking an input and converting it into a class or a likelihood that it belongs to that class is termed as image classification. For use in image processing applications, traditional machine learning models necessitate formal image processing, denoising, feature extraction, and dimensionality reduction. Deep learning eliminates the requirement for it. It is a subset of machine learning that has grown in popularity as processing units have improved, data sizes have grown larger, and research in the field has increased. In this paper, CNN is used to classify images of various machined surfaces. This study shows how to identify and classify machined surfaces such as turned, shaped, and ground surfaces using a 2D-CNN, deep learning-based machine vision inspection method. The goal of utilizing this model is for the surfaces to be detected properly the majority of the time, and for the model to run efficiently even for limited datasets. This model employs ReLU, Sigmoid, softmax activation functions, max pooling layers, and optimizers to learn unusual, unique patterns and determine what should be fed to the adjacent neuron. The proposed method is used to improve performance with a large image dataset, which comprises of various machined surfaces. When small datasets are supplied to the 2D-CNN, the model is more likely to overfit. To prevent this from happening, data augmentation can be used to produce higher, near-accurate outcomes with a smaller dataset fed to the suggested model. The proposed model produces the best results and demonstrates that without the usage of external computational resources such as a GPU, CNN can perform efficiently and produce improved and near-accurate results. In addition, when comparing the model proposed in this work to traditional machine learning approaches like ANN, it can be inferred that CNN provides better outcomes and accuracy using the same datasets as inputs to the models presented.

Authors: Yadav Siddharth , Yadav Vishal , Singh Daksh ManMahendra
Published: January 2023

India is one of the fastest growing nations within the global. To sustain this growth, power and power demands will increase. In this article, the present state and perspectives of using various energy sources in India for electric power generation are discussed as well as the main tools for promoting their development and utilization are highlighted. Indian power generation sector is the most expanded one in the world. Sources for power generation range from commercial ones such as coal, lignite, natural gas, oil, hydro and nuclear power to other important nonconventional sources such as wind, solar, agriculture and domestic waste. The demand for electricity in the country has been growing rapidly and is expected to grow further in the coming years. In order to meet this increasing requirement of electricity, massive addition to the installed generating capacity in the country is required. The demand of electricity has been increasing continually due to the increase in population, urbanization and usage of technology to access a comfortable life. It is also predicted that there will be a high demand of electricity by the year 2030. The Indian power sector is currently undergoing from a significant change that is redefining the outlook of the industry. The Government of India is currently focussing to attain 'Power For All' and has accelerated capacity addition in the country. In fact, the Power industry's future in India is bright, and sustained economic growth continues to drive electricity demand in India. Both energy and climate policies must be prepared for such a development in advance.

Regionally and internationally, the competition between languages is increased because of globalisation. Both sociolinguistic and Journalistic schools have extensive evidence of how quickly and unpredictably English has expanded over the world in comparison to other major languages. By addressing the grey area between Journalism and Philosophy of Ethics, the study explores teleological use of English words in the editorial contents of mainstream Urdu Newspapers of Pakistan. It categorizes the Urdu words used in two mainstream Urdu newspapers i-e Jang and Nawa-i-Waqt into further categories to take an in depth analysis of their usage. The method used is content analysis. All the hypotheses are proven on the findings of P value as 0.000. The findings revealed that Daily Nawa-i-Waqt used more common English words in their editorial as compared to Daily Jang in the taken universe.

This study explore and analyse rhetoric of political leaders of some selected parties of Pakistan during election campaign. For this purpose, speeches of political leaders of the three mainstream political parties were studied from sources including YouTube, TV shows and tweets. Content analysis method was used to analyse the data. Various forms, modes and types of rhetoric have been identified which were subsequently contextualized with the speeches, advertisements and rhetoric of the political leaders of the selected parties. Four themes including argumentations, storytelling, credit claiming and partisan cueing were extracted from the selected speeches. It was found that political elites and party leaders are so wisely manage to generate arguments, counter arguments, illustration and storytelling. The study also found that elites seems very justifiable by telling the stories and arguments but later on there is no substantial evidence in the form of performance, success and public service. The study concludes that the rhetoric used by party leaders are mostly directed towards political opponents and party leaders of other parties and less focused on the public policies and programs of general interest.

Molecular Detection of some Staphylococcal species with the newly developed folp gene sequences
Authors: Mohamed Adel El-Sokkary Mohamed
Published: January 2023

16SrRNA gene sequencing, universally accepted for bacterial identification could not effectively discriminate some closely related Staphylococcal species. For this reason, for bacterial species identification, other DNA sequencing genes are required. In this study, folp gene, encoding DHPS, was tested as a possible and alternative phylogenetic marker for more closely related Staphylococcal species. In this new method, 813 bp were implemented for classification instead of 1447 of 16S rRNA mostly used. Phylogenetic analysis was performed based on DNA sequences obtained from the GenBank including most important Staphylococcal species. As a result, the 16S rRNA-based tree clearly delineated 7 distinct clusters with high bootstrap values (1000) at distance adjusted to 5. Staphylococcus aureus, Staphylococcus epidermidis, Staphylococcus hominis, Staphylococcus haemolyticus and Staphylococcus saprophyticus were identified in separate clusters. However, 2 mixed clusters were resolved including Staphylococcus epidermidis and Staphylococcus warneri in one cluster, while Staphylococcus pasteuri and Staphylococcus warneri in the other one. Comparatively, the folp gene-based tree yielded 9 clusters with at distance adjusted to 5 and 1000 bootstrap value. Staphylococcus haemolyticus, Staphylococcus hominis, Staphylococcus haemolyticus, Staphylococcus ludunensis, Staphylococcus epidermidis, Staphylococcus aureus, Staphylococcus saprophyticus, Staphylococcus pasteuri were resolved in separate clusters, however, Staphylococcus warneri and Staphylococcus epidermidis were identified in one mixed cluster. In addition, DNA-DNA relatedness studies indicated high sequence divergence of folp gene exhibiting 61.58-96.48 % interspecies homology compared to 16S rRNA with sequences similarities of 97.09-99.32 %. At the intraspecies level, the nucleotide substitution rates were ranged between 0-25%, mostly at low level for most Staphylococcal species compared to 98.65-99.93 identified in 16S rRNA gene. Moreover, in blind tests, this method was able for correct identification of 13 bacteria isolates of different Staphylococcal species. As a conclusion, folp gene sequences provide better resolution compared to the 16S rRNA gene sequences for both interspecies and interspecies DNA analysis of Staphylococci.

Coumarins and chalcones have been molecules of considerable interest amongst medicinal chemists owing to their vivid pharmacological potentials including anticancer. A few coumarin-chalcone conjugates (C1-C5) with good antioxidant potential were evaluated for in vitro cytotoxicity against A549 cell lines using MTT assay. The IC50 of the conjugates was calculated after 24 h of treatment. The compounds C3 and C4 with higher mesomeric effects exhibited by the substituents were found to be possessing significant cytotoxic potential with IC50 values of 22.90 ± 2.1, 26.73 ± 6.6 µM respectively.

Kombucha is a fermented drink from herbs that provides many benefits for health, including antioxidant activity. Katuk (Sauropus androgynus (L.) Merr. ) leaves and kelor (Moringa oleifera Lam) leaves are common vegetables in Indonesia, and these plants were reported to contain natural antioxidants. This study aims to examine the antioxidant activity of single and mixture of katuk and kelor leaves before and after fermentation with Kombucha and identify the bioactive compounds of those samples. Katuk and kelor leaves were collected around the Serang Banten area. Antioxidant activity analysis was performed using free radicals DPPH method. Total phenolic content (TPC) and total flavonoids content (TFC) were measured. Compounds identification was conducted using liquid chromatography-mass spectrometry (LC-MS/MS). The results showed that the mixture of katuk and kelor fermented with Kombucha (KoKtKl 3:1) in the 50µl sample had the highest antioxidant activity (80.5% inhibition of DPPH), while under the same conditions, the unfermented sample only had 56.1% DPPH inhibition. Fermentation of katuk and kelor leaves with Kombucha for 7 days decreased pH, and increased antioxidant activity, TPC and TFC. The samples with the highest antioxidant activity (KoKtKl 3:1) were identified as containing kaempferol-3-O-rutinoside, kaempferol-3-O-β-D-glucopyranoside and quercimetrin, which are flavonoid glycosides that may be responsible for the antioxidant activity. In conclusion, katuk and kelor leaves showed antioxidant activity before and after fermentation with Kombucha, both as single preparations and mixtures which showed the potential to be studied further as a functional beverage for antioxidants.

Abstract:
Purpose: COVID – 19 which is still the leading health problem in the world, is not yet fully understood, therefore the study aims to investigate the posterior segment of the eye in patients with COVID – 19 using optical coherence tomography (OCT).
Materials and Methods: The present study was designed prospective and cross-sectional. Patients with a positive test result of COVID – 19 and healthy controls who were older than 18 years were included in the study. Excluded from the study were the patients with any systemic comorbidity and ocular disease. The demographic and clinical data, including ocular findings and the OCT data, including hyper-reflective (HR) lesions, retinal nerve fiber layer (RNFL), ganglion cell complex (GCC), and macular thicknesses (MT) were recorded as outcomes and analyzed.
Results: Twenty patients with SARS-CoV-2 and 20 healthy subjects were included in this study. There was no difference between COVID -19 patients and healthy controls in terms of the RNFL, GCC, and macular thicknesses (P > 0.05). HR lesions were detected in 18(45%) eyes of 9(45%) patients with COVID – 19 and 15(37,5%) eyes of 8(40%) healthy subjects’ retinae with no significant difference between groups (P = 0.165).
Conclusions: Hyper-reflective lesions could only be retinal vessels' tangential cuts seen in OCT B-Scans. There was not enough data that could indicate posterior segment involvement of COVID – 19.

The paper studies the implementation of a new transformer station in a network designed to take over some of the existing consumers, to provide the necessary energy for a number of new consumers and a reserve for future new connections to the electricity grid. By creating a fuzzy model, a number of rules have been created to highlight the power consumtion regimes, manifested at the level of the transformer station. Also, the possibility of optimizing and taking over from existing clients was created so that a balance and an optimization can be created regarding the disposition of the consumers on each station.
