Published: July 2023

Search engine optimization (SEO), the practice of improving website visibility on search engines, faces the considerable challenges posed by the opacity of Google’s relevance ranking algorithm. Attempts at understanding how this algorithm operates have generated a sizeable number of studies in the worlds of both business and academia. Indeed, this research tradition has managed to present strong evidence regarding the participation of certain factors and their relative importance. For instance, there is a widespread consensus that domain authority is one of the key factors in optimizing positioning. This study seeks to determine the reliability of the domain authority scores provided by three leading platforms for SEO professionals: Moz’s Domain Authority, Semrush’s Authority Score, and Ahrefs’ Domain Rating, values obtained using different indices and applying different procedures. We hypothesize that the degree of coincidence is high, allowing us to deduce that the three tools are, therefore, highly reliable. The method of data triangulation is used to compare the values from these three sources. The degree of coincidence is determined using a statistical analysis based on Spearman’s correlation coefficient (rho). The sample of domains analyzed was selected from 61 neutral queries, which provided 16,937 results and a total of 3,151 domains. When examining the tools in pairs, the correlation coefficients obtained were above 0.9 in all cases. The rho coefficient of the global analysis was also 0.9. This confirms our hypothesis and demonstrates that the three platforms can be considered as providing reliable data. These results are clearly relevant given that SEO professionals depend heavily on domain authority values in their work, and the degree of reliability detected ensures that decision-making based on this indicator can be undertaken with confidence.

Published: July 2023

Objective: To evaluate the performance of three scores, the Pediatric Index of Mortality 3 (PIM-3), the Pediatric Logistic Organ Dysfunction 2 (PELOD-2), and the modified PELOD-2 scores, in predicting mortality in multiple organ dysfunction syndrome (MODS) children in Vietnam.Material and Methods: This cross-sectional study of MODS children admitted to the pediatric intensive care unit (PICU) of a central children’s hospital in the Mekong Delta, Vietnam, was undertaken from April 2019 to June 2021. All three scores were evaluated using receiver operating characteristic (ROC) curves for discrimination and the Hosmer-Lemeshow goodness-of-fit test for calibration.Results: Of eighty-four subjects, the median age was 24.5 months and the overall mortality rate was 63.1%. ROC curve analysis showed that the area under the curve of PIM-3, PELOD-2, and modified PELOD-2 for predicting the death of MODS children were 0.77, 0.89, and 0.89, respectively. With individual cut-offs, the PIM-3, PELOD-2, and modified PELOD-2 scores had sensitivities for predicting mortality of 81.1%, 79.2%, and 81.1%, respectively, and specificities of 61.3%, 87.1%, and 80.6%, respectively. All three scores performed well in the Hosmer-Lemeshow goodness-of-fit test, indicating high calibration between predicted and observed mortalities (PIM-3: χ²=4.36, p-value=0.823; PELOD-2: χ²=4.837, p-value=0.775; modified PELOD-2: χ²=6.082, p-value=0.638).Conclusion: The PELOD-2 and modified PELOD-2 scores showed a better mortality prognosis than the PIM-3 score. Compared to the PELOD-2, the modified PELOD-2 with fewer parameters can still predict mortality well in Vietnamese children with MODS when using a cut-off score ≥9.

Objective: To investigate the reasons leading cancer patients to visit an emergency room (ER) and the associated factors, which will suggest policies to reduce unnecessary ER visits.Material and Methods: A cross-sectional study was done in Songklanagarind Hospital, the major referral center in Southern Thailand. The data of cancer patients aged 18 years or older diagnosed during 2011 to 2018 were retrieved from our Hospital Information System. The reasons for the ER visits were defined and classified using the “chief complaints” from doctors’ notes. A negative binomial regression model was used to assess factors associated with the ER visits.Results: A total of 42,574 cancer patients were identified during the study period. 8,307 (19.5%) had visited the ER at least once. The most common cancer type was of the digestive organs (28.1%). The top 5 reasons for an ER visit were pain (25.4%), dyspnea (11.5%), abdominal discomfort (6.0%), fever (5.9%), and stoma and catheter device-related problems (5.2%). The most common factors associated with ER visits were age, metastasis, palliative chemotherapy or radiotherapy, previous hospitalization, years with cancer, type of cancer and healthcare scheme.Conclusion: Pain and dyspnea were the two most common chief complaints leading cancer patients to visit the ER. These two symptoms should be given special attention in cancer patients, especially those receiving chemotherapy or radiation, to ensure they are well controlled and do not lead to unnecessary ER visits.

Kekerasan seksual merupakan isu yang sedang hangat-hangatnya di lingkungan kampus Unpad Jatinangor, bermunculannya akun-akun di media sosial yang berisikan photo-photo pelaku kekerasan seksual dan terbentuk SATGAS PPKS yang berfokus pada penanganan kasus kekerasan seksual merupakan bukti nyata bahwa isu ini memang terjadi di lingkungan kampus. Kasus kekerasan seksual di kampus Unpad Jatinangor juga dirasa masih belum mendapatkan penanganan dengan maksimal sehingga masih banyak kasus yang tidak terselesaikan dengan baik, hal ini dipengaruhi oleh alur pengaduan yang belum diketahui oleh seluruh civitas akademik termasuk mahasiswa. Kekerasan seksual yang terjadi di kampus pun didukung oleh beberapa faktor seperti kondisi lingkungan kampus. Penelitian ini bertujuan untuk mengkaji keterkaitan antara kondisi fisik serta lingkungan dengan kekerasan seksual di kampus Unpad Jatinangor dengan mengacu kepada Stimulation Theory dan Behavioral Setting Theory. Metode yang digunakan pada penelitian ini adalah metode penelitian kualitatif. Hasil penelitian yang didapatkan menjelaskan bahwa kekerasan seksual dipengaruhi oleh adanya lingkungan fisik kampus yang sepi, gelap dan sulitnya menjangkau pos-pos keamanan, serta kurang terawatnya serta ketersediaan fasilitas sarana dan prasarana seperti CCTV.  Jalanan sepanjang rumpun SOSHUM dan SAINTEK, lorong-lorong gedung dan toilet menjadi beberapa titik yang berpotensi menjadi tempat terjadinya kekerasan seksual. Diperlukan aksi nyata serta kontribusi dari berbagai elemen sehingga isu ini bisa mendapatkan prioritas untuk mendapatkan penanganan dengan tepat. Seperti perbaikan sarana dan prasarana ataupun sosialisasi yang menyeluruh dan berkelanjutan mengenai upaya pencegahan serta penanganan kasus kekerasan seksual.

Published: July 2023

Relevance. Vaccination of the child population against pneumococcal infection (PI) has been carried out in the Republic of Tatarstan according to the national calendar of preventive vaccinations since 2014. The vaccination scheme includes vaccination with PCV-13 conjugated pneumococcal vaccine.

Aim. Study of the the frequency of bacterial transmission and the serotype landscape of S. pneumoniae isolated from healthy children- bacterial carriers of preschool age in the Republic of Tatarstan (RT).

Materials and methods. During the period from 2016 to 2022, 1,426 children from Kazan and the districts of the Republic of Tatarstan were examined. Examination of nasopharyngeal smears was carried out by the classical bacteriological method. Serotyping was performed using molecular genetic methods (PCR).

Results. The detection rate of S. pneumoniae among healthy preschool children varied in different years from 29.5 to 63%, averaging 38.5%. In urban children, the incidence of pneumococcal transmission was significantly higher than in rural children (p<0.01). Also, when analyzing the serotype landscape, mixed colonization by several serotypes was observed. As of January 1, 2021, the immune layer to the pathogen PI among preschool children was 81.7%. Monitoring of the serotype landscape of S.pneumoniae strains circulating in the RT showed the dominance of vaccine serotypes (67.2%), of which 44.4% are PCV13 serotypes. The proportion of non–vaccinated serotypes is 26%, untyped - 6.8%. Unvaccinated serotypes 35B (21.3%) and 23A (13.6%) dominated in vaccinated children, as well as serotypes not included in the PKV-13 vaccine cocktail, but included in the PPSV-23 polysaccharide vaccine not used for vaccination of children, namely 11AD (15.3%) 9LN (9.6%). In unvaccinated children, on the contrary, vaccine serotypes included in PCV-13 prevailed: 6ABCD (17.3%), 19F (20.9%), and unvaccinated serotypes 11AD, 9LN, 35B, 23A were detected with lower frequency 11,8%, 10,0%, 4,2%, 7,3% accordingly.

Conclusion. Data on the regional features of the pneumococcal serotype landscape can be the basis for expanding the vaccine cocktail due to the dominant serotypes: 9LN,11 AD, 35B, 23A.

Published: July 2023

Relevance. This study is related to the study of the etiology, pathogenesis and clinic of inflammatory bowel diseases (IBD). In a number of patients with IBD who are refractory to anti-inflammatory/immunosuppressive therapy, there are signs of current or transferred yersiniosis infection, not diagnosed by routine methods.

Aim. According to the scientific literature and the results of our own research, to identify the presence and assess the nature of the influence of yersinia on the occurrence and development of IBD.

Materials Methods. In our study, we conducted a bacteriological examination of feces by polymerase chain reaction (PCR) in patients with a diagnosis of IBD (UC and CD) in the acute phase (MMDAI ≥ 4 points for UC and Best index ≥ 150 points for CD), as well as immunological diagnostics using enzyme immunoassay (IFA) in the version of line-blotting (IB). Using the results obtained, clinical and instrumental semiotics were evaluated in subgroups of individuals suffering from IBD with confirmed yersiniosis ("IBD+ IER+") and without it ("IBC+ IER–"). We also assessed the role of intestinal infection by determining the effectiveness of initial antibacterial therapy in the treatment of exacerbation of IBD.

Results. A significant part (in the case of our sample – 45%) of patients with IBD, when examined by high-tech methods, demonstrate the presence of markers of a transferred or current yersiniosis infection. Its role in the initiation and development of autoimmune intestinal inflammatory process requires further clarification.

Conclusions. In 45% of patients with IBD, high-precision examination reveals markers of transferred or current yersiniosis infection. Routine clinical methods for the diagnosis of yersiniosis have low sensitivity and do not allow us to convincingly assess the role of this bacterial agent as a trigger factor for the onset or recurrence of IBD. There is a tendency for greater manifestation in the debut of IBD in patients with markers of systemic yersiniosis. The fact of improvement against the background of empirical antibacterial therapy in 24% of patients with IBD, achievement of early clinical remission in 57% of patients receiving antibiotic therapy, indicates a significant role of bacterial enterocolopathogens in the genesis of chronic intestinal inflammation in a number of patients.

Authors: Sergevnin V. I. , Ratnikova S. M. , Zueva N. G. , Rozhkova M. V.
Published: July 2023

Relevance. Employees of medical organizations (MO), by virtue of their official duties, are at the group risk of morbidity of a new coronavirus infection.

Aim. Evaluation of the manifestations of the COVID-19 epidemic process and the epidemiological effectiveness of the use of the Gam-Covid-Vac vaccine among employees of a multy-speciality medical organization.

Materials and methods. The incidence of COVID-19 among the staff of MO was studied for the period from March 2020 to December 2021. The latent epidemic process was evaluated avccording to the results of routine serological examination of employees for antibodies of classes IgM and IgG to SARS-CoV-2. The epidemiological effectiveness of immunoprevention was determined by comparing the incidence with the coverage of employees who has a completed course of vaccination.

Results. During the study period, 47.7% of employees of medical organizations had a clinically apparent form of COVID-19. In addition, according to the results of a routine serological examination, it turned out that 46.5% of employees had a subclinical form of infection. An increased level of morbidity was observed in the autumn period. The incidence of medical workers was in 2.2 times higher than other employees, medical staff of the hospital – in 1.7 times higher than polyclinics. The epidemic process was more intense in the group of nurses than doctors and junior medical staff. The epidemiological efficacy of the Gam-Covid-Vac during the first months of using vaccine has been established. Vaccinated people have a more mild course of COVID-19 in comparison with unvaccinated people.

Conclusion. In this way, the main manifestations of the COVID-19 epidemic process in employees of a multy-speciality medical organization were identified and the epidemiological effectiveness of the Gam-Covid-Vac vaccine in the first months of using vaccine was established

Authors: Yermalovich M. A. , Kolodkina V. L. , Samoilovich E. O. , Semeiko G. V. , Mikhalenko A. O.
Published: July 2023

Relevance. Serological studies play an important role in assessing the spread of SARS-CoV-2 and formation of post-infection and post-vaccination immune response.

The Aims aim of the study was a comparative assessment of seroprevalence and concentration of antibodies to SARS-CoV-2 at 3–6 months after infection or vaccination.

Materials & Methods. For the presence of total IgM and IgG antibodies to RBD fragment of the SARS-CoV-2 S protein, the blood sera of 1331 people aged 18-70 years were examined, of which 334 had COVID-19 3–6 months before the study, 305 did not have COVID-19 and were vaccinated (using Sputnik V, Russia, or Sinopharm, PRC) 3–6 months before the study, 692 people were not ill and were not vaccinated. A quantitative assessment of IgG antibodies to the full-size S-protein of SARS-CoV-2 was performed for 435 samples.

Results. The proportion of seropositive individuals 3–6 months after COVID-19 or after vaccination did not differ: 92.5% and 93.8% of the corresponding group had antibodies. Among the non-ill and unvaccinated, 45.7% also had specific antibodies, which indicates a high level of asymptomatic infection with SARS-CoV-2. The group of vaccinated was also examined immediately before the introduction of the vaccine, and 39.7% of them already had specific antibodies due to asymptomatic infection with SARS-CoV-2. The median concentration of antibodies in the group of COVID-19 was statistically significantly higher than in asymptomatically infected (50.9 AE/ml versus 29.1 AE/ml). The largest proportion of seropositive individuals (100.0%) and the highest concentration of antibodies (110 AE/ml) were detected in the group of vaccinated who had pre-existing antibodies.

Conclusion. Infection with the SARS-CoV-2 is characterized by a high frequency of subclinical course. Asymptomatic infection induced a weaker immune response compared to symptomatic COVID-19 or vaccination. Hybrid immunity caused by natural infection with SARS-CoV-2 and subsequent vaccination was the most persistent and pronounced.

Authors: Kostinov A. M. , Tarasova A. A. , Mashilov K. V.
Published: July 2023

Relevance. Community-acquired pneumonia and chronic obstructive pulmonary disease (COPD) remain a serious public health problem in all respects today.

Aims. To summarize the studies of domestic authors on the study of the effect of pneumococcal polysaccharide vaccine on various parts of the immune system and their relationship with the clinical course of the disease in patients with COPD and community-acquired pneumonia. We also consider it necessary to discuss the possible mechanisms of therapeutic effects after the introduction of a monovaccine against S. pneumoniae, as well as when it is combined with vaccines against Haemophilus influenzae type b infection, and the effectiveness of various vaccination regimens, including complex ones.

Conclusions. Convincing arguments are presented proving that the introduction of vaccines against respiratory infections can have not only a reventive value, but also a therapeutic effect, accompanied by a transient restoration of the immune system parameters, as well as a reduction in the contamination or elimination of S. pneumoniae in patients with chronic pathology of the bronchopulmonary system.

Published: July 2023

The article focuses on the relevance of the issues of formation and implementation of the intra-corporate policy of digitalization of marketing of agrarian enterprises. It was established that the aspects of digitization and realization of its potential directly in the segment of agricultural enterprises in Ukraine are still not sufficiently developed.

Therefore, the purpose of the study is to improve the methodological and applied principles and provisions of identification and substantiation of directions for strengthening the digitalization of marketing of agricultural enterprises. The advantages of the formation and development of digital management systems at domestic enterprises in general, as well as directly in the field of digitalization of their marketing systems and complexes, are emphasized. Prospective directions of digitalization of marketing of agrarian enterprises are determined by the following components: (1) product policy, (2) price policy, (3) policy of promotion and stimulation of product sales, (4) policy of product positioning on the market.

The problematic aspects of the formation of an environment of digital marketing of agricultural enterprises in Ukraine are reflected. The strategic stages of the policy of development and expansion of the priority directions of digital marketing of agrarian business entities have been determined. The system of structural blocks of the program of digitalization of agricultural enterprise marketing is substantiated, in particular - initial conditions, policy goal, goals and directions of regulation, globalization block, financial-resource and organizational-management support, monitoring and adjustment tools. The toolkit for monitoring the digitalization of marketing of agricultural enterprises has been defined, which involves taking into account the system of indicators in three groups: (1) development of the intra-corporate digital system, (2) digital modernization of business processes, (3) harmonization and convergence of intra-corporate digital systems into the global system of the digital economy of Ukraine and the EU.
Molefe on Wiredu's Humanistic Interpretation of Akan (African) Ethics
Authors: Agada Ada
Published: July 2023

In his 2015 Theoria article titled ‘A Rejection of Humanism in African Moral Tradition’, Motsamai Molefe argues that Kwasi Wiredu's humanistic interpretation of traditional Akan ethics cannot be the best account of African ethics because Wiredu overlooks the significant sentiment in traditional African thought that regards reality as a holistic totality of spiritual, social and environmental components. I point out that Molefe's rejection of Wiredu's humanism follows from the latter's de-emphasising of supernaturalism. I argue that Molefe overlooks the fact that the displacement of God in this humanism is consistent with the limited God sentiment in traditional African thought, which confirms Wiredu's humanistic ethics as one rooted in traditional African worldviews. Adopting the method of philosophical exposition and analysis, I show how Wiredu's limited God framework motivates scepticism about the possibility of a supernaturalist ethics and renders a humanistic orientation a more attractive account of African moral tradition.

Authors: ÖZTÜRK Emre
Published: July 2023

In this paper, we define a nonlinear transformation between space curves which preserves the ratio of $\tau/\kappa$ of the given curve in 3−dimensional Euclidean space $E^3$. We investigate invariant and associated curves of this transformation by the help of curvature and torsion functions of the base curve. Moreover, we define a new curve (family) so-called quasi-slant helix, and we obtain some characterizations in terms of the curvatures of this curve. Finally, we examine some curves in the kinematics, and give the pictures of some special curves and their images with respect to the transformation.
FHD flow in an irregular cavity subjected to a non-uniform magnetic field
Authors: ŞENEL Pelin
Published: July 2023

In this paper FHD flow in a rectangular pipe constricted by two analogous semi-cylinders attached to the left and the bottom walls is investigated. The laminar, axial flow is produced by a constant pressure gradient, and the flow is affected by a spatially varying non-uniform magnetic field caused by two electric wires. The current-carrying wires are placed along the axes of the semi-cylinders. The fully developed flow is studied on the 2D cross-section of the pipe, a cavity, where the wires act as point magnetic sources. The pressure equation is added to the mathematical model, and the velocity-pressure form governing equations are numerically solved by the dual reciprocity boundary element method (DRBEM). The Dirichlet type pressure boundary conditions are approximated through a process using the radial basis functions and a finite difference. The flow, velocity, and pressure variations are investigated for different magnetic field strengths and current ratios. The grid independence study is also carried out. The proposed iterative scheme is capable of generating numerical results by performing a non-uniform discretization for the boundary. Dense discretizations are applied at the places where the flow shows a sudden fluctuation. It is shown by the numerical results that the flow and the pressure variations are dominated by the strong magnetic source. With an increment in the magnetic number, the planar flow is accelerated, the axial flow is decelerated, and the pressure increases, especially around the strong point magnetic source.
Analysis of a production inventory system with MAP arrivals, phase-type services and vacation to production facility
Authors: ÖZKAR Şerife
Published: July 2023

In this paper, we discuss a production inventory system with service times. Customers arrive in the system according to a Markovian arrival process. The service times follow a phase-type distribution. We assume that there is an infinite waiting space for customers. Arriving customers demand only one unit of item from the inventory. The production facility produces items according to an (s, S)-policy. Once the inventory level becomes the maximum level S, the production facility goes on a vacation of random duration. When the production facility returns from the vacation, if the inventory level depletes to the fixed level s, it is immediately switched on and starts production until the inventory level becomes S. Otherwise, if the inventory level is greater than s on return from the vacation, it takes another vacation. The vacation times are exponentially distributed. The production inventory system in the steady-state is analyzed by using the matrix-geometric method. A numerical study is performed on the system performance measures. Besides, an optimization study is discussed for the inventory policy.
Chromatic Schultz polynomial of certain graphs
Authors: NADUVATH Sudev
Published: July 2023

A topological index of a graph $G$ is a real number which is preserved under isomorphism. Extensive studies on certain polynomials related to these topological indices have also been done recently. In a similar way, chromatic versions of certain topological indices and the related polynomials have also been discussed in the recent literature. In this paper, the chromatic versions of the Schultz polynomial and modified chromatic Schultz polynomial are introduced and determined this polynomial for certain fundamental graph classes.
New summability methods via $\widetilde{\phi}$ functions
Authors: SAVAS Rabia
Published: July 2023

In 1971, the definition of Orlicz $\widetilde{\phi}$ functions was introduced by Lindenstrauss and Tzafriri and moreover in 2006, the notion of double lacunary sequences was presented by Savaş and Patterson. The primary focus of this article is to introduce the double statistically $\widetilde{\phi }$-convergence and double lacunary statistically $\widetilde{\phi }$-convergence which are generalizations of the double statistically convergence [19] and double lacunary statistically convergence [24]. Additionally, some essential inclusion theorems are examined.

On solutions of three-dimensional system of difference equations with constant coefficients
Authors: KARA Merve , AKTAŞ Ömer
Published: July 2023

In this study, we show that the system of difference equations
\begin{align}
x_{n}=\frac{x_{n-2}y_{n-3}}{y_{n-1}\left(a+bx_{n-2}y_{n-3} \right) }, \nonumber \\
y_{n}=\frac{y_{n-2}z_{n-3}}{z_{n-1}\left(c+dy_{n-2}z_{n-3} \right) },~n\in\mathbb{N}_{0}, ~ \nonumber \\
z_{n}=\frac{z_{n-2}x_{n-3}}{x_{n-1}\left(e+fz_{n-2}x_{n-3} \right) }, \nonumber \\
\end{align}
where the initial values $x_{-i}, y_{-i}, z_{-i}$, $i=\overline{1,3}$ and the parameters $a$, $b$, $c$, $d$, $e$, $f$ are non-zero real numbers, can be solved in closed form. Moreover, we obtain the solutions of above system in explicit form according to the parameters $a$, $c$ and $e$ are equal $1$ or not equal $1$. In addition, we get periodic solutions of aforementioned system. Finally, we define the forbidden set of the initial conditions by using the acquired formulas.
Practical Dimensions of the «Symphony» of St. Emperor Justinian: State Coercion and Church Law and Order
Authors: Пашков Д.
Published: July 2023

В статье рассматривается теория «симфонии» (согласия) гражданской и церковной власти («царства» и «священства»), изложенная императором Юстинианом I в преамбуле к его 6­й новелле (535 г.) в качестве ответа на доктрины пап конца V – начала VI вв. Геласия и Симмаха. Последние утверждали превосходство священства и исключительное его заведование церковными делами. В отличие от них, Юстиниан говорит не о соотношении двух иноприродных обществ, но о соотношении двух служений в едином церковногосударственном теле. При этом, ограничивая деятельность священства богослужением, императорская власть берёт на себя заботу «об истинных догматах» и «о чести священников», а также о соблюдении канонов, т. е. о церковном устроении.

The article considers the theory of “symphony” (consent) of civil and church power (“Kingdom” and “Priesthood”), set forth by Emperor Justinian I in the preamble to his 6th short story (535) as an answer to the doctrines of the popes of the late V – early VI centuries Gelasius and Simmach. The latter claimed the superiority of the priesthood and its exclusive charge of church affairs. In contrast, Justinian speaks not of the ratio of two foreign societies, but of the ratio of two ministries in a single church-state body. At the same time, limiting the activities of the priesthood to worship, the imperial government takes care of “true dogmas” and “the honor of priests,” as well as the observance of canons, i.e., Church arrangement.
Canonical Corpus and its Significance in the Modern Life of the Orthodox Church
Authors: Лапидус И.
Published: July 2023

Искажение в понимании природы Церкви неминуемо ведёт к нарушению канонов, так же как и систематическое нарушение канонов ведёт к искажению образа Церкви, потере живой связи с «Телом Христовым» (Кол. 1, 24). Существует тесная связь между аберрацией в экклезиологии и антиканоническими действиями, предпринятыми Константинопольским Патриархатом на Украине в 2018–2019 гг. Концепция, описывающая предстоятеля Константинопольской Церкви как «primus sine paribus», появилась много лет назад, и действия патриарха Варфоломея на Украине являются логическим следствием и актуализацией этой идеи. Отсутствие активного интеллектуального диалога между экспертными сообществами Поместных Церквей неминуемо ведёт к утрате взаимопонимания и к отсутствию возможности своевременного предупреждения опасных тенденций, в том числе и в интерпретации канонов. В статье делается вывод о необходимости широкой дискуссии по теме понимания и имплементации в Древней Церкви канонических норм, содержащихся в 9, 17 и 28 правилах IV Вселенского Собора, в виде конференций, круглых столов, качественных и быстрых переводов публикаций на европейские языки, в первую очередь на английский и греческий. Эта дискуссия со временем может привести к адекватному пониманию ключевых канонических норм Халкидонского Собора и к соответствующему оформлению канонической оценки действий ныне здравствующего Константинопольского предстоятеля Синодами Православных Поместных Церквей.

Distortion in the understanding of the nature of the Church inevitably leads to the violation of canons, as well as the systematic violation of canons leads to the distortion of the image of the Church, to the loss of the vivid connection with the “Body of Christ” (Col. 1, 24). There is a close connection between aberration in ecclesiology and the anti-canonical actions taken by the Patriarchate of Constantinople in Ukraine in 2018–2019. The concept describing the primate of the Church of Constantinople as “primus sine paribus” appeared many years ago, and the actions of Patriarch Bartholomew in Ukraine are a logical consequence and actualization of this idea. The absence of an active intellectual dialogue between the expert communities of the Local Churches inevitably leads to a loss of mutual understanding and to the lack of the possibility of timely prevention of dangerous trends, including in the interpretation of canons. The article concludes that there is a need for a wide discussion on the topic of the understanding and implementation in the Ancient Church of canonical norms contained in rules 9, 17 and 28 of the IV Ecumenical Council, in the form of conferences, round tables, high-quality and quick translations of publications into European languages, primarily English and Greek. This discussion over time may lead to an adequate understanding of the key canonical norms of the Council of Chalcedon and to the corresponding formalization of a canonical assessment of the actions of the Constantinople Primate by the Synods of the Local Orthodox Churches.
