Authors: Dandavate Nupoor , Gadkari Nitin , Rajbhoj Ashwin , Patil Mayur , Gaikwad Naineesh , Bankar Ashwin
Published: June 2023

Background: Anemia is particularly prevalent in India due to widespread malnutrition. Cancer related anemia affects about three-fourths of cancer patients, causing symptoms like fatigue, appetite loss, and difficulty concentrating, and can worsen cancer prognosis, lengthen treatment, and reduce survival rates. Anemia is a significant cause of tumor hypoxia, which exacerbates the side effects of radiotherapy and chemotherapy, and affects energy levels and emotional distress.
Methods: The present cross-sectional study aims to assess the prevalence and types of anemia in patients with newly diagnosed non-luminal solid tumors. The study sample included all patients meeting the inclusion criteria, with a sample size of 100. Clinical evaluation and investigations were carried out to determine the presence and severity of anemia. Data was compiled and analyzed.
Results: Of the 100 patients enrolled, 68% had evidence of anemia, and the majority of them were in the age group of 51-60 years. Anemia’s association with body mass index (BMI) was noted and was more common in underweight and normal-weight patients. The commonest malignancies in the study were head and neck cancers, breast cancers and female genital cancers, and the incidence of anemia in these malignancies was higher than in other tumors. When sub-classified a higher prevalence in gynecological tumors was noted. The majority of anemic patients had mild anemia, with microcytic hypochromic anemia being the most common type.
Conclusions: The study provides valuable information on the incidence and severity of anemia in patients with non-luminal solid tumors, which can help clinicians in their treatment planning and management.

AIM: To evaluate effects of endogenous dopamine induced by low concentration atropine eye drops on choroidal neovascularization (CNV) in high myopia mice.
METHODS: The C57BL/6J mice were deprived of the right eye for 4wk, and the high myopia was diagnosed by optometry, the diopter was less than -6.00 D, and CNV was induced by 532 nm laser. The changes of dopamine D1 receptor (DRD1), dopamine D2 receptor (DRD2), and vascular endothelial growth factor A (VEGFA) were detected by Western blot technology at 0.5, 1, 2h, and 7d after 0.01%, 0.05%, and 0.1% atropine eye drops, respectively, the area of CNV was measured.
RESULTS: Significant increases were observed on the expression of DRD2 in mouse high myopia model at 0.5, 1, 2h, 7d with 0.05% and 0.1% atropine eye drops (P<0.05). Significant decreases were observed on the expression of DRD1 and VEGFA in mouse high myopia model at 0.5, 1, 2h, 7d with 0.05% and 0.1% atropine eye drops (P<0.05). The area of CNV induced by laser in the drug-treated group was significantly smaller than that in the control group, and the higher the concentration, the more significant the inhibitory effect (P<0.05).
CONCLUSION: The 0.01%, 0.05%, 0.1% atropine eye drops can decrease the level of VEGFA and inhibit high myopia CNV indirectly by up-regulating the level of DRD2 and down-regulating the level of DRD1, and the effect of 0.05% and 0.1% atropine eye drops is more significant.
İlk Dönem Eş‘arî Kelâmcılarını Âdet Teorisini Kabule Sevk Eden Âmiller
Authors: ŞERMET Sümeyra , CENGİZ Lütfü
Published: June 2023

Kelâm ilmi Allah’ın varlığı ve sıfatlarını ispatlamayı amaçlamaktadır. Bu amaç etrafında kelâmcılar, duyulur âlemden gaybî alana yönelen bir yöntem benimsemişlerdir. Kıyâsü’l-ğāib alâ’ş-şâhid şeklinde isimlendirilen bu yöntem, muhaliflerle yapılan tartışmalarda ortak bir zemin oluşturmuştur. Çünkü duyulur âlem inkâra mahal vermeyecek şekilde insan algısına açıktır. Bundan hareketle Eş’arî kelâmında “Allah dışındaki her şey” şeklinde tanımlanan âlem hem yapı hem işleyiş itibariyle ele alınmaya çalışılmıştır. Kelâmcıların belirledikleri ilkeler etrafında âlemin cevher, araz ve cisimlerden oluştuğu söylenmiştir. Bahsi geçen varlıklar en temelde birbirine, ayrıca daha üst bir iradeye bağımlı bir şekilde kurgulanmıştır. Eş‘arî gelenek bu kurgudan hareketle âlemin işleyişini âdet teorisi ile açıklamayı tercih etmiştir. Hatta onların âleme ve Allah’a yönelik temel kabulleri bu tercihi zorunlu kılmıştır. Çünkü onlar Allah’ı mutlak irade ve kudret sahibi fâil-i muhtar bir ilah olarak tasavvur etmektedir. Âlemde akıl tarafından imkânsız görülen olay ya da durumlar haricindeki her şey, O’nun kudreti dâhilindedir. Bu yönüyle âlem mümkünler mecrası şeklinde nitelenmektedir. Özellikle arazın bâkî olmayan yapısından hareket eden Eş‘arî gelenek, arazların her an yeniden yaratılması gerektiği görüşünü ısrarla savunmaktadır. Bu temel savunu da âlemin Allah’a olan bağımlılığını tümüyle gözler önüne sermektedir. Bu temel kabuller üzerine inşa edilen âdet teorisi, mutlak irade ve kudret sahibi Allah’a herhangi bir sınırlama getirmeden âlemin işleyişini özgün bir şekilde açıklamaktadır. Eş‘arî geleneği birebir yansıtan bu teori, onların başta Allah-âlem ilişkisi olmak üzere tüm kelâmî meseleleri tutarlılık içinde açıklamalarına olanak sağlamaktadır. İşte bu çalışma ilk dönem Eş’arî geleneği âdet teorisini kabule sevk eden temel ilkeleri başlıklar halinde ele alarak irdelemeyi amaçlamaktadır. Bu amaç etrafında literatür taraması yapılarak tespit edilen ilk dönem Eş’arî kelâmcıların görüşleri incelenmiş, konu bağlamında yorumlanmıştır.

Published: June 2023

Asthma is a common chronic airway inflammation that produces a healthcare burden on the economy. We aim to obtain a better understanding of the clinical status and disease burden of patients with asthma in China.
A retrospective study was carried out based on the computerized medical records in the Jinan Health Medical Big Data Platform between 2011 and 2019 (available data from 38 hospitals). The asthma severity of each patient was assessed retrospectively and categorized as mild, moderate, or severe according to Global Initiative for Asthma 2020 (GINA 2020).
The results revealed that the majority (75.0%) of patients suffered from mild asthma. Patients treated with inhaled corticosteroids (ICS)/long-acting beta-agonists (LABA) at emergency department visits had lower frequencies of exacerbations compared with non-ICS/LABA-treated patients. The incidence rates for 1, 2, 3, and 4 exacerbation of the patients treated with ICS/LABA are lower than those treated without ICS/LABA (14.49 vs. 15.01%, 11.94% vs. 19.12%, 6.51% vs.
12.92% and 4.10% vs. 9.35%). The difference got a statistical significance Chronic obstructive pulmonary disease (COPD) and gastroesophageal reflux disease (GERD), two comorbidities related to asthma, were risk factors for asthma exacerbation. Finally, patients who suffered from exacerbations produced a heavier economic burden compared to the patients who never suffered exacerbations (mean costs are ￥3,339.67 vs. ￥968.45 separately).
These results provide a reference for clinicians and patients to obtain a better treatment and therapy strategy management for people living with asthma.

Published: June 2023

Introduction: Some accurate tools exist to assess fear-avoidance behavior, such as the Tampa scale for kinesiophobia (TSK) in individuals with musculoskeletal problems. The current research aims to compare the psychometric characteristics of the original Persian 17-items TSK questionnaire and its 11-item brief version in chronic non-specific low-back pain (CNSLBP).
Materials and Methods: In this test development study, 295 patients with CNSLBP referred to the physiotherapy clinic of Milad Hospital in Tehran city, Iran were evaluated. Confirmatory factor analysis (CFA) and α Cronbach was conducted to assess the validity and reliability of the original and brief Persian version of the TSK, respectively. For goodness-of-fit, the Χ2/df, root mean square error of approximation (RMSEA), goodness-of-fit index (GFI), and comparative fit index (CFI) indices were used.
Results: Internal consistency specified by Cronbach’s α was 0.949 for the original version of the questionnaire and 0.927 for the brief one. Based on the CFA findings, the goodness-of-fit indices for the brief version were GFI=0.921, RMSEA=0.078 (90% confidence interval (CI), 0.062%-0.094%), comparative fit index (CFI)=0.981, and Χ2/df=2.791. These indices for the original one were 0.882, 0.066 (90% CI, 0.055%-0.076%), 0.983, and 2.270, respectively.    A significant correlation was found between these two versions (P<0.001). These findings confirm the adequacy of the brief version of the TSK.
Conclusion: The brief Persian version of TSK can be considered a reliable and valid tool to evaluate somatic focus and activity avoidance in patients with CNSLBP.
Subcortical Role in Figurative Processing by Persian- speaking Alzheimer and Parkinson’s Patients
Authors: Azad Omid
Published: June 2023

Introduction: The production of figurative expressions, particularly idioms, and proverbs, is negatively affected by damage to the left hemisphere and subcortical area of the brain. Alzheimer patients, thanks to the preservation of basal ganglia, can produce these expressions. In contrast, compared to Alzheimer’s patients, Parkinson’s patients cannot produce these expressions due to the malfunction of the basal ganglia. This study attempts to compare the linguistic and cognitive performance of Persian-speaking patients with Alzheimer’s disease, Parkinson’s disease, and healthy counterparts regarding the production and comprehension of these figurative expressions.
Materials and Methods: In doing so, by selecting a sample  of participants  composed  of  10 Alzheimer’s patients, 10 Parkinson’s patients, and 10 healthy individuals matched with each other regarding age and education. Then, different tests, including Arizona battery for communication disorders of dementia, famous names, and face test, structured conversation, figurative expression completion, elicitation of response based on situational context, Northridge evaluation of idioms and proverbs in situational context, conventional and figurative expression evaluation were condcuted to analyze their performance.
Results: The results of Arizona battery for communication disorders of dementia indicated that Alzheimer’s patients were in the middle stage of the disease while Parkinson’s participants were classified as non-dementia patients. Although the result of the Renown face and name recognition test demonstrated a significant difference between Alzheimer’s patients and the healthy group regarding cognition and confidence levels, the same result was not observed between healthy control and Alzheimer’s patients. Furthermore, in the test of structured conversation, the proportion of produced words by Alzheimer’s patients was more than that of Parkinson’s patients. However, the results of sentence and figurative expression completion tests corroborated the weaker performance of Alzheimer’s patients compared to their Parkinson and healthy counterparts. Furthermore, notwithstanding in the test of Elicitation of response based on Situational Context, Parkinson’s patients performed more poorly than their Alzheimer and healthy counterparts, in the tests of conventional and figurative expression evaluation, Alzheimer’s patients’ pattern of performance was different from that of other groups as they performed more weakly than Parkinson patients.
Conclusion: The observed dissociation in the performance of Alzheimer as well as Parkinson’s patients in the linguistic production and comprehension tests shed light on the significant role of the subcortical area of the brain in the production of idioms and proverbs.

Authors: Gholami Samaneh , Torkaman Giti , Bahrami Fariba , Bayat Noushin
Published: June 2023

Introduction: The knee is the most affected weight-bearing joint by osteoarthritis. The kinetics parameters are correlated with the progression of knee osteoarthritis (KOA). This study was done to investigate the relationship between kinetics parameters and functional tests with Western Ontario and McMaster Universities osteoarthritis index (WOMAC) scores in people with moderate KOA.
Materials and Methods: Twenty- three participants with moderate KOA participated in this study. Gait analysis involved the measurement of the external peak knee adduction moment (PKAM), peak knee flexion moment (PKFM), knee adduction moment impulse (KAM impulse), and knee flexion moment impulse (KFM impulse) during level walking. Functional tests included timed up and go (TUG) and figure of eight walkings (FO8W) tests. Pearson’s correlation coefficient was used to investigate the correlation between kinetics parameters and functional test scores with WOMAC total scores and sub-scores.
Results: There was a significant inverse correlation between the first PKAM and WOMAC total score and pain sub-score (r=-0.43 P=0.03 and r=-0.6 P=0.002, respectively). Also, there was a significant inverse correlation between the second PKAM and pain sub-score (r=-0.46 P=0.02). There was no significant correlation between functional tests and WOMAC scores.
Conclusion: The low score of the WOMAC in the moderate KOA should not be attributed to the low level of joint knee moments.

Published: June 2023

Introduction: In individuals with anterior cruciate ligament deficiency (ACLD), defective sensory and motor neuroplasticity occurs in the central nervous system (CNS) due to defects in sensory afferents. To successfully restore ACLD individuals to pre-injury conditions, it is necessary to modify the neuroplasticity created in the CNS by prescribing more appropriate training. For this aim, in this study, we used perturbation training differently.
Materials and Methods: Thirty athletes with unilateral anterior cruciate ligament (ACL) rupture were randomly assigned to the perturbation and standard training groups. The training program of two groups was performed in three intermittent sessions per week for one month. The relative power spectrum of alpha of quantitative electroencephalography (QEEG) was measured in three tasks: (1) the single-leg jump-landing, (2) the single-leg stance with opened eyes, and (3) the single-leg stance with closed eyes.
Results: The perturbation training group only showed significant symmetry in the relative power spectrum of alpha between the two limbs in the single-leg jump-landing test (P=0.92, ES=0.04) in comparison pre-post test. Also, this group showed high symmetry in the alpha band in the single-leg stance test with closed eyes (P=0.53, ES=0.16).
Conclusion: The results of the present study  showed  that  both  mechanical  perturbation and standard training are suitable for transporting ACLDs back to sports. It also seems that mechanical perturbation training had higher effectiveness in modifying the CNS alpha power.

Trachyspermum ammi (L.) Sprague (commonly known as ajwain) contains ingredients that attenuate menstrual problems, especially cramping. In this study, we evaluated the impact of ajwain on the pain intensity in a sample of Iranian female college students with primary dysmenorrhea (PD) in comparison to mefenamic acid (MFA). This study was an open-label, randomized, parallel-group clinical trial conducted in the university dormitories in Tehran, Iran, from September 2018 to May 2019. Seventy patients were randomly assigned to two groups of ajwain and MFA. The participants in the ajwain group were treated with a 500 mg ajwain capsule three times a day for seven days, from the 26th cycle day to the 3rd day of the menstrual cycle, for three consecutive cycle periods. The other group received MFA capsules with the first dose of 500 mg and then 250 mg every eight hours, if necessary, from the first day of the menstrual cycle. The two groups were compared in terms of the pain intensity by the visual analog scale (VAS) in pre-intervention cycle and three consecutive cycles during the study. Maximum pain intensity, mean pain, and duration of pain after the intervention were significantly reduced in both groups. The mean VAS score significantly decreased in the ajwain group compared to the MFA group post-intervention (p < 0.02). Moreover, passing blood clots was significantly reduced in the ajwain group (p < 0.03). The findings of this study suggest that ajwain may be effective in pain relief in PD without adverse effects.

Type 2 diabetes (T2DM) and its complications can cause severe morbidity and mortality. The researchers and clinicians’ attention has been toward finding an efficient treatment for T2DM to decrease its heavy burden on the people and countries. Whey protein (WP) is a known glucose-lowering treatment of traditional Persian medicine. This randomized controlled clinical trial aimed to evaluate the efficacy of the WP on the improvement of the glycemic index of the patients with T2DM in Fars, Fasa, Iran. A total of 58 patients with T2DM met the inclusion criteria and were randomly assigned to one of two groups: intervention or placebo. For 12 weeks, they were given 1 sachet of WP or 1 sachet of placebo. Before and after the trial, fasting blood sugar (FBS), lipid profile, and liver enzymes were tested. Finally, 35 patients completed the study (18 in the whey group and 17 in the placebo group). The mean ± standard deviation of age, BMI, and the disease duration in placebo group were 52.1±9.2 years, 26.8±3.9 kg/m2 and 102.9±67.7 months and in WP group were 51.2±8.2 years, 25.7±3.7 kg/m2 and 74.2±51.1 months. There were no significant differences among the study groups at the beginning (P>0.05). Meanwhile, the WP and placebo groups were the same by means of the amount of anti-diabetic drugs that participants consumed (P=0.242). After 12 weeks FBS and hemoglobin A1C amounts showed remarkable decreases in the WP group compared to its starting point (P=0.011 and P=0.001 respectively); while in the placebo group, no significant difference was observed (P>0.05).  No severe complications were reported in the two groups. In conclusion, we found that whey protein would be a promising complementary therapy to control hyperglycemia in the patients with T2DM.

The Stachys genus is a medicinal plant, with 34 different species, from Lamiaceae family that grows in Irano-Anatolian plateau. There are 12 species of Stachys native to Iran. Some species of Stachys have been used in traditional medicine of Iran, Turkey, Italy, Greece, China, and Japan for the treatment of various diseases like inflammation and common cold. Some researchers have noted many biological effects, such as cytotoxic, antioxidant, immunomodulator, anti-inflammatory and antibacterial effects for the members of this genus. There are a few evidences on phytochemical constituents of S. byzanthina. The aim of this study was phytochemical investigation of various extracts of this plant to obtain the most efficient fractions and compound(s) to study the antimicrobial effects of this plant. Separation and isolation of compounds was performed by various methods of chromatography. The structure of each compound was identified by spectroscopic methods. Antimicrobial studies were performed on different fractions of S. byzantina by microdilution method and to determine the Minimum Inhibitory Concentration (MIC), agar well diffusion was done. Ethyl acetate fraction has the highest total phenol contents (1082.05 mg GAE/g fraction) and antioxidant capacity (IC50= 1.23 mg/mL). Also, ethyl acetate fraction, the most potential fraction of S. byzanthina, demonstrated the largest inhibition zone (17.5 ± 0.7 mm) with 5 mg/mL in MIC against Staphylococcus auresus. Apigenin and its derivatives were isolated from this fraction and according to literature; they can be responsible for antibacterial activity of this fraction of S. byzanthina.

Published: June 2023

Fatigue is a complex phenomenon that is explained as difficulty starting or keeping voluntary physical or mental activity leading to negative impacts on life and work performance. This study aimed to investigate the anti-fatigue effects of Viola odorata L. in an animal model. Aqueous and ethanol extracts of V. odorata were prepared and total phenolics content was determined. Then, the anti-fatigue activity of the extracts was evaluated via a weight-loaded forced swimming test in the rat. To this end, 48 male Wistar rats were randomly classified into 6 groups. The control group using distilled water and other groups with ethanol (EVO; 50, 100, 200 mg/kg) and aqueous extracts of V. odorata (WVO; 50, 100mg/kg) were gavaged once daily for four weeks. Then, the forced swimming was conducted and swimming time, as a fatigue factor was measured. In addition, to validate the effect of V. odorata on the endurance capacity of the rats, biochemical factors including glucose, lactate dehydrogenase (LDH), and tumor necrosis factor (TNF-α) were examined in the serum. Hepatotoxicity was also assessed using hematoxylin-eosin staining. Our data indicated that the forced swimming time of the EVO-100, EVO-200, and WVO-100 groups was significantly increased. The serum glucose in the group which received EVO-200 was increased significantly; while serum LDH levels in all treated groups were significantly decreased. Also, the serum level of TNF-α in the groups which received EVO-100 or 200 was increased significantly. However, there was no considerable difference in serum TNF-α level and no hepatotoxicity within aqueous extract groups. Pathology results showed fewer effects of the aqueous extract rather than ethanol extract on the liver. The results provide evidence for the development and use of V. odorata aqueous extract as an anti-fatigue supplement.
Encuadres y estereotipos de género: avances y cambios en la cobertura mediática de las mujeres políticas. El caso de Claudia López en Bogotá y Manuela Carmena en Madrid
Authors: Cárdenas Arias Valeria
Published: June 2023

Diversos estudios evidencian que las mujeres políticas enfrentan mayores obstáculos en su acceso al poder que se ven normalizados y potencializados por el papel de los medios de comunicación. Contrario a sus homólogos hombres, las mujeres en la política tienden a recibir un tratamiento distinto por parte de los medios. En este artículo se analiza el problema de los estereotipos de género como catalizadores de encuadres en la cobertura mediática de las campañas electorales y los periodos de gobierno de Claudia López en Colombia y Manuela Carmena en España. La metodología utilizada es mixta, y se analizaron en total 394 publicaciones de los dos periódicos digitales más leídos de cada país, con el objetivo de identificar los encuadres estereotipantes y profundizar el análisis en dos de las variables: el tema de la esfera íntima y lo relacionado con el liderazgo y los “roles de género”. A la luz de los resultados, eltiempo.com y semana.com en Colombia, así como elmundo.es y elpais.es en España, se pudo evidenciar que los medios de comunicación siguen usando encuadres que refuerzan el sexismo y que se traducen en una cobertura mediática diferenciada, que además varía en tiempos de campaña y épocas de gobierno.

The Convergence of Factors That Affect the Dairy Product Market: A Comparative Analysis of European Union Countries
Authors: Klapkiv Jurij , Putsenteilo Petro , Karpenko Vitalii
Published: June 2023

The European Union is a large producer of milk and dairy products. It is also a significant market for the consumption of dairy products, which is characterised by effective demand, and it significantly influences the markets of other food products. The main milk producers in the EU are Germany, France, Poland, the Netherlands, Italy and Spain. Intensive migration has contributed to additional demand for food products, in particular, dairy products. This provided the basis for the construction and calculation of a dynamic model of dairy production, the export of dairy products, and the coexistence with the existing population as the main consumers in the EU–27 countries and Great Britain between 2004 and 2020.

An additional research value is that based on the presentation of the analysis and modeling, the relationship between the growth in the demand for dairy products and the growth in the population is established. The reason for the large population in the countries of Central and Eastern Europe is intensive migration flows, which increase the demand for dairy products. The increase in volumes reduces the cost price, which contributes to the export of dairy products, and also contributes to the increase in the volume of production of dairy products. The resulting models made it possible to analyse the influence of population growth on the increase in production volume. At the same time, the dependence and influence of the export of dairy products on the increase in the volume of production of dairy products in the EU–27 and Great Britain countries is investigated.

The results of the mathematical modelling indicate unique opportunities to develop the dairy sector of individual EU–27 countries, i.e., the Czech Republic, the Netherlands, and Poland. These countries have a rational ratio of the influence of the population growth factor on the increase in the volume of dairy production and the optimal influence of the export of dairy products on the increase in the volume of dairy production.

Authors: Lebre-Rodrigues Claudia , Nakamura Wilson Toshiro , Mendes Johnny Silva
Published: June 2023

This research investigates the determinants of ROE and the impact caused by the Covid-19 pandemic on public companies in Latin America. The fixed effects regression model with panel data is used to identify that factors related to sales policies and cost controls are the ones that contribute the most to ROE performance, regardless of the period. On the other hand, the level of indebtedness and macroeconomic indicators are not significant, strengthening the finding that the operational and internal decisions of the company contribute more strongly to maximizing shareholder returns. This verification helps financial managers in directing decisions and expands academic knowledge on this topic.

The Russian economy and financial market are facing a wide range of challenges under the unprecedented sanctions pressure. The anti-crisis measures promptly taken by the Bank of Russia and the Government of the Russian Federation stabilized the situation, focusing the agenda on the restoration and further development of the Russian economy and financial market in the new realities. Considering that the extraordinary change in circumstances is likely to last for a long time and will have structural consequences, it is necessary to develop systemic solutions for development of the Russian economy and the financial market, to reorient the economy on innovative tracks in order to ensure technological sovereignty. For such a transition in the context of the reduction of the country’s investment potential, “long money” plays a significant role, as President of Russia Vladimir Putin has repeatedly said. A promising way to solve the problem can be savings of the population, as one of the possible significant sources of investment resources for effective restructuring and improvement of the domestic economy. However, it is important to understand whether there are conditions today for the formation of savings by the population and opportunities for their further investment in the country’s economy. The current socio-economic situation of the country, as well as the state of the financial market, reflects the possibility of implementing various models of financial behavior of the population, due to such factors as income, trust and affordability, which are reflected in the “3D effect”. The author singled out these factors as fundamental in the formation of an individual’s economic behavior program when it comes to the available resource potential, as well as the environment in which the program is implemented. In the course of the study, it was found out that the components of the “3D effect” reflect negative trends in the formation of the financial behavior of citizens, in particular, their savings and investment strategies. In this connection, there are acute questions related to ensuring a qualitatively new level of the resource base, as well as the environment.

Convergence and depopulation processes in the Center-Periphery system
Authors: Zhulego Vladimir , Balyakin Artem , Sorokin Mikhail
Published: June 2023

The paper proposes advancement of a stratum demographic model characterized by the presence of two strata — the Center and the Periphery, which are different in respects of their way of life, development level and social values. The processes of convergence and depopulation in the heterogeneous system of the Center-Periphery type were studied. Various variants of “catch-up development” of the Periphery are considered within the framework of numerical simulation. Modes of economic growth that contribute to the convergence of income levels in the countries of the Center and the Periphery are indicated, depending on the value of the characteristic time of convergence. There are identified the regimes of a stable and supposedly irreversible depopulation of the Periphery. It is shown that economic participation of the Center in changing the situation in the Periphery countries might be necessary to achieve economic convergence for maintaining the stability of the entire system. As an explanatory principle of the observed phenomena, the institutional trap concept is proposed. A number of socio-economic interpretations of the dynamics of the Center-Periphery system as well as the possibility of the System behavior control by appropriate management decisions are discussed on the results of computer modeling. Further development of the proposed model may include studying other scenarios of economic interaction and taking into account additional demographic and migration parameters in the equations of economic growth.
Interpretation of digitalization indicators of the Russian system of general education
Authors: Skvortsova Elena
Published: June 2023

The article analyzes digitalization indicators of the Russian general education system provided by the Federal State Statistics Service (Rosstat) and the Unified Interdepartmental Information and Statistical System (EMISS), as well as data from a secondary analysis of the results of the sociological survey “Teenagers 360°” (within the framework of the strategic program “Teenagers Russia” of the Commissioner for Children’s Rights under the President of the Russian Federation) and other sources. The following indicators are considered as indicators: the indicator of the use of special software tools available to students in educational organizations; the number of students using e-learning and distance learning technologies; the number of students in organizations engaged in educational activities under additional general educational programs for children; the proportion of children attending additional educational classes; the purposes of using the Internet by children. Their dynamics over the past few years is traced. The interpretation of the digitalization impact on education is presented at the quantitative and qualitative levels. There are analyzed the opinions of specialists in the field of social and pedagogical sciences, teachers and physicians directly related to education and childhood on the digitalization impact on health, mental abilities, assimilation of knowledge and acquisition of craft and work skills. It is concluded that the excessive introduction of digital technologies in all sectors of domestic general education, including additional school education, can interfere with acquisition and systematization of basic knowledge and not contribute to upbringing of the younger generation in a traditional and moral way. Digital educational innovations are perhaps useful as additional educational tools, but only with a quality and serious content.
Meal 'n' Knowledge. Review of the book «Science In The Media: Popular Images and Public Perceptions»
Authors: Sokolov Dmitry
Published: June 2023

The article discusses the book "Science In The Media: Popular Images and Public Perceptions" by Paul Brewer and Barbara Lay of the University of Delaware. The book touches upon the issue of media representation of science and scientists and provides an analytical overview of the different media (from children's TV shows to social media posts) that shape the perception of science among a wide audience. The book is based on American material, but the trends noted by the authors, as well as the conclusions drawn, are important not only for the USA, which gives their work additional value. The authors collected, classified and sociologically processed a huge array of materials, and were able to outline the most effective ways to promote scientific knowledge in society, while helping to understand the inevitable limitations of various media channels of communication between the scientific community and the public. In addition, the authors, tracking the logic and priorities of various media (serials, TV shows, news programs, and so on), along the way explain the paradox of passion for pseudoscience against the backdrop of an abundance of scientific information. Instead of complaining about the superficiality of journalists and TV shows, the authors suggest that scientists, firstly, carefully choose programs for cooperation, secondly, take into account the specifics of a particular media format when working with it, and, thirdly, use the digital environment more actively to advance scientific points of view.
Features and Problems of Developing a University Scientometric Policy
Authors: Osipov Mikhail
Published: June 2023

The subject of research in this article is the regularities of the process of developing the scientometric policy of the university and the methodology for assessing its effectiveness. In the course of the study, it was found that in order to increase the efficiency of organizing and conducting scientific research in universities, it is necessary to have a certain scientometric policy of the university, which is a set of actions and decisions aimed at determining certain quantitative scientometric indicators both for the organization as a whole and for individual employees of the organization: how many publications should be published on behalf of the organization per year, in which publications certain articles should be published, what should be the average impact factor of the journal, where certain articles and other scientific publications should be published, how many publications are needed, how many should to be cited or what should be the Hirsch index for occupying a particular position in a scientific organization or an educational organization of higher education, what are the necessary resources to achieve the goals, what factors will contribute to the achievement of the goals and objectives of the scientometric field and which ones will hinder this and how to neutralize the hindering factors. It seems that the presence of such a scientometric policy is one of the most important conditions for increasing the efficiency of scientific research in universities. The paper also analyzed the factors influencing the effectiveness of scientometric policy in educational institutions of higher education. Ways to improve the effectiveness of scientometric policy in universities are proposed, which include the following areas: a) the availability of a specialized course dedicated to the specifics of scientific research; b) the university has a unified scientometric policy; c) overcoming myths and stereotypes in the field of scientific research and publication of their results

Perusahaan Daerah Air Minum (PDAM) Way Rilau Kota Bandar Lampung mengolah air sungai Way Kuripan sebagai baku air bersih. Hingga saat ini, pemantauan kekeruhan dan padatan terlarut (TDS) air baku untuk menentukan dosis koagulan dalam pengolahan air masih dilakukan secara konvensional. Sementara, kualitas fisik air baku bersifat fluktuatif, terutama dipengaruhi curah hujan. Akibatnya, seringkali dosis tidak cukup untuk proses koagulasi/flokulasi sehingga air olahan masih keruh. Penelitian bertujuan membuat prototype alat pengukur kekeruhan dan TDS berbasis Internet of Things dengan sistem sensor. Alat dikembangkan menggunakan microcontroller ATMega-328P, sensor kekeruhan TS-300B, sensor TDS ESP-8266, dan modul SIM-800L V.2. Prinsip kerja alat dengan menangkap nilai kekeruhan dan TDS oleh sistem sensor, selanjutnya data diolah oleh microcontroller dan diteruskan melalui Modul SIM800L V.2 ke penerima (smartphone/PC) melalui jaringan internet. Hasil penelitian mendapatkan tingkat akurasi yang tinggi pada pengukuran kekeruhan (96,89%) dan TDS (97,55%). Analisis statistik tidak menunjukkan perbedaan hasil pengukuran antara prototype dengan alat ukur standar pada kedua parameter (p-value>0,05). Sedangkan kecepatan transfer data selama 30 detik. Hasil penelitian ini menunjukkan bahwa prototype mampu memberikan hasil pengukuran kekeruhan dan TDS secara valid, berbiaya murah, dan real time.
A esfera social no trabalho da arte: relações entre forma e contexto político na obra de Antônio Dias
Authors:   Universidade de São Paulo, Rivetti Lara Cristina Casares
Published: June 2023

Existe um conjunto de trabalhos de Antonio Dias (1944 - 2018), produzido entre cerca de 1963 e 1966, que ocupa um lugar central na sua trajetória. Dias começou a produzir muito cedo, já no final da década de 1950, quando frequentou, como aluno especial, a Escola Nacional de Belas Artes (onde teve aulas com o gravurista Oswaldo Goeldi, do qual foi assistente) e os cursos ministrados por Ivan Serpa e Aluísio Carvão, na escola de artes do Museu de Arte Moderna do Rio de Janeiro / MAM-RJ. É verdade que esses trabalhos inaugurais são ainda incipientes, tateantes e pouco representativos de aspectos que viriam a se revelar como centrais em sua obra. Mas logo nos primeiros anos da década seguinte, surgiu uma produção que demonstrava fôlego para responder às questões colocadas para os artistas naquele momento, e na qual já se encontravam formuladas, com maior contundência, algumas das reflexões que, mais tarde, seriam tomadas como pontos centrais de toda a sua obra.
