UNLOCKING THE POWER OF BIG DATA: DIGITAL TRANSFORMATION OF PUBLIC POLICY IN DPRD DKI JAKARTA
Authors: Gemiharto Ilham
Published: December 2023

This research delves into the prospects and obstacles associated with utilizing large-scale data in developing public policies within the Indonesian context. Integrating big data technology holds promise as a tool for government agencies aiming to refine the public policy formulation process, ultimately providing enhanced services to the populace. Despite its inherent complexity and costliness, incorporating big data offers the government a means to furnish the most up-to-date, precise, and granular information pertinent to developmental issues. For instance, in the agricultural sector, big data can offer an intricate understanding of the diverse requirements of farmers in distinct regions, such as the differentiation between rice varieties sought by farmers in Kalimantan compared to those in Java. Furthermore, the expansive reservoirs of geophysical and meteorological big data hold the capacity to significantly bolster the government's initiatives concerning natural disaster mitigation policies. Nonetheless, the practical integration of big data still needs to be improved by a dearth of comprehensive regulations governing its application. Additionally, the perils of recurrent data breaches in the Indonesian context pose a formidable challenge. This comprehensive analysis concludes that using big data in policy formulation within Indonesia encounters substantial hurdles that threaten to overshadow the potential advantages this technology could offer in enhancing public policy crafting.

Campaigns carried out by the Ministry of Health and other government collaborations will not be successful without mass media broadcasts. Hence a phenomenon occurs that there is still a lack of discussion regarding the media raises the issue of stunting in the media. Thus this study aims to find out how concerned the media is in news portals regarding child stunting issues in Indonesia. The theory which is used in this study is the theory of health communication and online reporting. This study uses a post-positivistic paradigm, a digital media content analysis method with a qualitative approach. The data collection technique captures big data regarding stunting news in the news portal during November 2022 on National Health Day. The results of the study show that the online news portal with high awareness is tribunnews.com around 528 news out of 750 news. The most widely published issue is the government's commitment to reduce the stunting rate in Indonesia and the government's campaign programs as evidence of a concrete movement to increase public awareness regarding the prevention and treatment of stunting in society. The benefits of this research are expected to further strengthen the insights of researchers both in terms of expertise and scientific competence of researchers.

Chemo mechanical preparation is one of the important stages for successful endodontic treatment, and Boric acid has been proposed as an alternative irrigation solution for root canal treatment. Objective: The purpose of this study was to evaluate the effect of irrigation with boric acid (BA) and EDTA on the mineral content and microhardness of dentin and penetration of the AH Plus root canal sealer. Methods: 63 single-rooted teeth were instrumented. Microhardness analysis, 45 teeth were cut longitudinally and then transversely to obtain dentin. Pre- and post-treatment microhardness values were measured. The samples were randomly assigned into 3 groups (n = 15) for irrigation solution: distilled water, 17% EDTA, and 5% BA. The 18 roots were irrigated with three solutions (n = 6). Nine of the roots were filled with AH-Plus for confocal laser scanning microscopy analysis, and the others were used for XRD analysis. Results: The results were evaluated with the ANOVA test. BA caused a significant decrease in microhardness value in apical and coronal parts (p < 0.05), while EDTA reduced only in coronal parts (p < 0.05). Conclusion: BA provided higher sealer penetration ability. BA reduced the microhardness and provided better sealer penetration.

Objective: The aim of this study was to evaluate the position, angulation and surrounding trabecular bone structure of a unilateral impacted maxillary canine (IMC) tooth using fractal analysis. Methods: Cone beam computed tomography images of 50 patients (38 female, 12 male) with unilateral IMC were selected for this retrospective study. A 25x25 pixel region of interest (ROI) was selected in the trabecular bone between the premolars on the impacted and non-impacted side and fractal analysis was conducted. The angulation of unilateral impacted canines was measured and the position was categorized as vestibular, intra-alveolar and palatal. Results: Of the 50 impacted teeth, 42% were in the vestibular, 26% were in the intra-alveolar, and 32% were in the palatal position. The most common angulation angle of the IMC was 0°-15° which occurred in 44% of canines. While the bone fractal values did not statistically significantly differ between the sides, the values were 1.05 ± 0.9 on the impacted side and 1.04 ± 0.1 on the non-impacted side. No significant difference was observed in fractal values according to the position and angulation angles of the impacted maxillary canine (p > 0.05). Conclusion: The structure of trabeculation around the impacted canine tooth was no different than on the non-impacted side.

Malocclusion’s negative impact is not only limited to dentofacial appearance but also related to quality of life. Nowadays, orthodontic treatment can be done using conventional fixed appliances, or removable appliances called clear aligners. The preference for orthodontic appliances can be affected by several factors, including patient characteristics, self-perception, psychosocial, and oral-disorder factors. Objective: This study aims to evaluate the factors affecting the preference for orthodontic appliances among undergraduate students in West Jakarta. Methods: In this cross-sectional study, 244 undergraduate students were retrieved by purposive sampling from 7 universities located in West Jakarta. A self-administered questionnaire was used to collect data, and logistic regression analysis was carried out. Results: Fixed orthodontic appliances were commonly used (79.5%), and the majority of treatment providers were orthodontists (64.8%). Students’ belief that poor dental alignment is related to decreased social attractiveness was significantly associated with the preference for orthodontic appliances (p = 0.026; 95% CI = 1.170-11.317). Orthodontic treatment provider was significantly associated with a preference for orthodontic appliances (p = 0.000; 95% CI = 0.678-3.156). Conclusion: Fixed orthodontic appliances still become the main preference for malocclusion treatment among undergraduate students in West Jakarta. Besides that, the qualification of orthodontic treatment providers affects the preference for orthodontic appliances among undergraduate students in West Jakarta.

Published: December 2023

Este artículo de reflexión se ocupa de investigar, desde un enfoque cualitativo con revisión bibliográfica, en describir y analizar de manera crítica los problemas probatorios que supone la imputación del delito de feminicidio en Colombia; particularmente en lo relacionado con los estándares probatorios que permiten acreditar el elemento contextual o la intencionalidad subjetiva del autor de causar la muerte a una mujer en razón de su sexo o en el marco de una violencia estructural de género. En este sentido, se cuestiona la capacidad probatoria del ente acusador para acreditar fehacientemente tal circunstancia, al tiempo que se realiza una revisión del ejercicio de valoración probatoria que realiza el juez frente a esta clase de delitos, así como la indeterminación, de cara a los principios de tipicidad y legalidad, que dicha interpretación supone en perjuicio del procesado.
Analysis of 5G Rotman beamforming lens antenna for higher beam angle and minimum phase error
Authors: Parsediya Deep Kishore , Singhal Pramod Kumar
Published: December 2023

Rotman lens beamforming networks are widely used for high gain, wide bandwidth applications in 5G communication. The uniform amplitude and phase distribution along with wide angle scanning at the array ports are mostly demanded for reducing the losses. Furthermore, minimum phase error is essential requirement for lens designs. Conventionally, for wide angle scanning, the lenses are designed by using most common expression between beam angle α and focal ratio (parameter ‘g’) i.e. g = 1 + 0.5α
2. The lenses obtained by such relation are inefficient for higher beam angle such as α = 45° due to the restricted shapes of beam and array contours. Hence suffer with large path length error limitation. In this paper, the mathematical relation between beam angle and focal ratio (parameter ‘g’) has been developed. The proposed relation offers phase error reduction more than 3× than the conventional expression based lens error. The simulation of the designed lens has performed using Software MATLAB which showed close agreement with the analytical values. Furthermore, three rectangular MPA arrays at center frequency 2.35 GHz have been proposed and simulated with lens design for 5G frequency range i.e. 2.3–2.4 GHz and offer high gain, directivity and wide coverage.
Numerical Determination of Target Values and Process Parameters of Case Hardening, Taking into Account the Local Stress State of Failure-Relevant Construction Details
Authors: Diemar A. , Gerth U. , Lahmer T. , Teichert G. , Könke C.
Published: December 2023

Through the thermochemical process of case hardening, the local material strength of steel components can be increased. In addition to the increase in stress due to the notch effect, the shape of construction details also has an effect on key component properties after case hardening, such as edge hardness and case hardening depth. The component-related specification of target values for case hardening is currently based on empirical values or expert knowledge. In addition, the effect of design details during case hardening is not taken into account when specifying process parameters in the control and regulation software of case hardening systems. This article presents a concept for the numerical determination of target values and process parameters for case hardening based on the stress state of the component. Compared to the empirically based determination of target values and process parameters for case hardening, the application of the concept makes it possible to adapt the case hardening of components to their stress in the failure range and thus significantly increase the energy and resource efficiency of case hardening.
The School of Salamanca on Value of Money: A Reassessment
Authors: Bahmanpour-Khalesi Mohammadhosein , Sharifzadeh Mohammadjavad
Published: December 2023

This study endeavors to investigate the theory of the value of money from the vantage point of late scholastic scholars, with a specific focus on the Salamanca School and the two prevailing monetary doctrines: Objectivism (Metallism) and Subjectivism (Chartalism). Our investigation employs the classical works of late scholastic thinkers from the 15th to the 17th centuries to illuminate the perspectives held by the Salamanca School concerning monetary value. The findings affirm that the twofold theory of money value proposed by late scholastic thinkers constitutes a nuanced iteration of the multidimensional approach to money. This comprehensive framework encompasses various facets of value, such as the final, actual, formal, and material dimensions. Moreover, the conspicuous emphasis placed by late scholastic thinkers on the subjective aspects of money value imparts a multifaceted character to their theory, demonstrating striking parallels with modern subjective doctrine.

Authors: Sotiropoulou Lamprini , Loupas Marios Athanasios , Adamopoulou Mary , Athanasiou Dimitris , Kalogeropoulou Maria
Published: December 2023

Background

Neurofibromatosis (NF) is a group of rare genetic disorders characterized by the development of tumours that may affect the brain, spinal cord, and the nerves that send signals between the brain and spinal cord and all other parts of the body. The disease burden on Greek patients and caregivers is unknown.

Objective

The aim of this study is to determine the societal economic burden and health-related quality of life (HRQoL) of families with neurofibromatosis type 1 (NF1) in Greece.

Methods

A cross-sectional study was conducted in which an online questionnaire was completed by NF1 patients and their caregivers. A cost of illness model was developed in which costs per NF1 patient were calculated from a societal perspective and extrapolated to the total affected population in Greece. Finally, the 36-item PedsQL™ Family Impact Module was used to measure the HRQoL of families with NF1 members.

Results

The economic burden of NF1 was estimated at €21,594 per patient in 2022. When extrapolating this outcome across all affected persons, the average annual cost was €56,319,583. Out-of-pocket expenses accounted for 10% of the total. Results of the analysis on HRQoL indicated a significant burden on family members representing the caregivers of NF1 patients with the majority of scores falling below 50 and a mean total score of 45.

Conclusions

The results highlight the considerable burden of NF1 not only in terms of the high costs but also in terms of reduced HRQoL for patients’ families.

Published: December 2023

Objectives

There are limited treatment options and no consensus on the management of advanced rare ovarian malignancies. Rare ovarian malignancies can present with peritoneal metastases (PM), featuring a similar presentation to more common ovarian subtypes. Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) is an effective treatment for PM of non-gynecologic origin and, recently, epithelial ovarian cancer. We evaluated the feasibility of CRS/HIPEC in the management of PM from rare ovarian malignancies and report postoperative outcomes on these patients.

Methods

A retrospective review of a single center, prospective database (1994–2021) was performed to identify patients with rare ovarian malignancies treated with CRS/HIPEC. Clavien-Dindo 90-day morbidity/mortality and Kaplan–Meier overall (OS) and progression-free survival (PFS) were analyzed.

Results

Of 44 patients identified, 28 underwent CRS/HIPEC. Six were aborted due to extensive disease. Histologic subtypes included: clear cell (5/28, 17.9 %), endometrioid (5/28, 17.9 %), granulosa cell (3/28, 10.7 %), low-grade serous (6/28, 21.4 %), mesonephric (1/28, 3.6 %), mucinous (6/28, 21.4 %), and small cell (2/28, 7.1 %) carcinomas. Eight (28.6 %) patients had primary and 20 (71.4 %) had recurrent disease. Median peritoneal cancer index (PCI) was 21 (IQR: 6–29). Complete cytoreduction (<2.5 mm residual disease) was achieved in 27/28 (96.4 %). Grade III/IV complications occurred in 9/28 (32.1 %) with one (3.6 %) mortality. After a median follow-up of 65.8 months, 20 patients were alive. Five-year OS and PFS were 68.5 and 52.6 %, respectively.

Conclusions

In patients with PM from rare ovarian malignancies, CRS/HIPEC is feasible and has an acceptable safety profile. Longer follow-up and multicenter trials are needed.

Published: December 2023

The relevance of this study is the increased interest of modern researchers in the field of humanities in the problems of interaction between language, culture, and thinking, as well as the need to study in this aspect the interdisciplinary notion of the concept from the position of literature studies. The purpose of the study is to investigate the concepts of “power” and “death” as key units in the conceptual framework of Kazakh writer Yessenberlin’s novel The Nomads: The Charmed Sword, and to determine the features of their reflection in the individual author’s language picture of the world. The leading method is the method of conceptual analysis, which makes it possible to identify and comprehensively consider concepts in both individual authors and the national picture of the world of the Kazakh people. Within the research, the hierarchical structure of the conceptual framework of Yessenberlin historical novel is presented. The authors calculated associative rows of the concepts composing the novel’s conceptual framework and made conclusions concerning the relationships between the studied concepts, as well as the meaning of the central concepts “power” and “death” and the distinction between historical facts and artistic fiction. The main statements and conclusions can be used in the process of teaching philological disciplines in higher education institutions.
Estimation of the Departmental Female Employment Rate: Towards a New Strategy Based on Combining Spatial and Non-spatial Small Area Estimators
Authors: Mahali Kamel
Published: December 2023

Local statistics are in high demand in almost all countries due to their relevance for public policy monitoring and evaluation, decision-making, and strategic planning. However, traditional sources of local statistics, such as general censuses, administrative statistics, and national and local surveys, have limitations. This has led to the development of several techniques for estimating parameters over small areas. In this article, we use both spatial and non-spatial estimators for small domains to estimate the local employment rate of women in Algeria. We find that the empirical spatial estimator is the most appropriate and efficient estimator as more spatial correlations are considered. We also find that an approach based on the combination of spatial and non-spatial small area estimators is very beneficial because it allows for obtaining efficient estimates with lower Root Mean Squared Errors (RMSEs). This finding is significant for Algeria and similar countries, where traditional sources of local statistics are limited. The combination of spatial and non-spatial estimators can provide more accurate and reliable estimates of local statistics, which can be used to inform public policy and decision-making.

Published: December 2023

Objectives

To assess the frequency of multiple thrombophilia-associated mutations and polymorphisms in a selected population of high-risk pregnancies.

Methods

Thrombophilia screening was performed for 1,500 pregnant women with prior pregnancy complications or thrombotic events. Nine thrombophilia-associated mutations or polymorphisms were screened: factor V Leiden, factor V H1299R, prothrombin G20210A,MTHFRC677T,MTHFRA1298C, factor XIII V34L,PAI-14G/5G polymorphisms,EPCRG4600A,EPCRC4678G.

Results

Out of the 1,500 patients, 1,291 fulfilled the criteria for data interpretation. All patients had low-risk thrombophilia-associated genetic variants. Only 1.24 % of cases presented high-risk abnormalities (homozygous factor V Leiden/prothrombin G20210A, or both mutations in heterozygous form). Heterozygous factor V Leiden occurred in 10.38 % of cases, while only 5.81 % carried heterozygous prothrombin G20210A mutation. The frequency of prothrombin G20210A mutation was higher (10.37 %) in the subgroup associating factor V Leiden, than in the subgroup lacking it (5.36 %). Low-risk genetic variants occurred with a higher frequency: 23.78 % factor V H1299R, 57.32 %MTHFRC677T, 55.54 %MTHFRA1298C, 44.07 % factor XIII V34L, 73.20 %PAI-14G/5G polymorphisms, 69.64 %EPCRG4600A, and 69.63 %EPCRC4678G.

Conclusions

All patients had at least one prothrombotic genetic mutation or variant. Our data highlight the need for thrombophilia screening, including low-risk genetic variants, in a high-risk population of pregnant women with a history of pregnancy complications or thrombotic events.

Published: December 2023

SCN2Aencodes NaV1.2, an excitatory neuron voltage-gated sodium channel and a major monogenic cause of neurodevelopmental disorders, including developmental and epileptic encephalopathies (DEE) and autism. Clinical presentation and pharmocosensitivity vary with the nature ofSCN2Avariant dysfunction and can be divided into gain-of-function (GoF) cases with pre- or peri-natal seizures and loss-of-function (LoF) patients typically having infantile spasms after 6 months of age.

We established and assessed patient induced pluripotent stem cell (iPSC) - derived neuronal models for two recurrentSCN2ADEE variants with GoF R1882Q and LoF R853Q associated with early- and late-onset DEE, respectively. Two male patient-derived iPSC isogenic pairs were differentiated using Neurogenin-2 overexpression yielding populations of cortical-like glutamatergic neurons. Functional properties were assessed using patch clamp and multielectrode array recordings and transcriptomic profiles obtained with total mRNA sequencing after 2-4 weeks in culture.

At 3 weeks of differentiation, increased neuronal activity at cellular and network levels was observed for R1882Q iPSC-derived neurons. In contrast, R853Q neurons showed only subtle changes in excitability after 4 weeks and an overall reduced network activity after 7 weeksin vitro. Consistent with the reported efficacy in some GoFSCN2Apatients, phenytoin (sodium channel blocker) reduced the excitability of neurons to the control levels in R1882Q neuronal cultures. Transcriptomic alterations in neurons were detected for each variant and convergent pathways suggested potential shared mechanisms underlyingSCN2ADEE.

In summary, patient iPSC-derived neuronal models of SCN2A GoF and LoF pathogenic variants causing DEE show specific functional and transcriptomic in vitro phenotypes.

Significance statementSCN2Aencodes one of the major brain voltage-gated sodium channels, NaV1.2, and is a major monogenic cause of neurodevelopmental disorders, including severe infantile epilepsy and autism. SCN2A pathogenic variants cause either gain or loss of channel function, which correlates well with the clinical phenotype. Gain of function variants are associated with early-onset seizures with or without developmental delay, whereas loss of function results in late-onset severe epilepsy and/or autism. We used patient-derived induced pluripotent stem cells to generate neuronal cultures for two recurring SCN2A variants causing early and late seizure onset epilepsy. Identified electrophysiological and transcriptome changes compared to the isogenic control lines can be correlated with the distinguishable clinical phenotype.
The Neural Dynamics of Face Ensemble and Central Face Processing
Authors: Sama Marco Agazio , Nestor Adrian , Cant Jonathan Samuel
Published: December 2023

Extensive work has investigated the neural processing of single faces, including the role of shape and surface properties. However, much less is known about the neural basis of face ensemble perception (e.g., simultaneously viewing several faces in a crowd). Importantly, the contribution of shape and surface properties have not been elucidated in face ensemble processing. Furthermore, how single central faces are processed within the context of an ensemble remains unclear. Here, we probe the neural dynamics of ensemble representation using pattern analyses as applied to electrophysiology data in healthy adults (seven males, nine females). Our investigation relies on a unique set of stimuli, depicting different facial identities, which vary parametrically and independently along their shape and surface properties. These stimuli were organized into ensemble displays consisting of six surround faces arranged in a circle around one central face. Overall, our results indicate that both shape and surface properties play a significant role in face ensemble encoding, with the latter demonstrating a more pronounced contribution. Importantly, we find that the neural processing of the center face precedes that of the surround faces in an ensemble. Further, the temporal profile of center face decoding is similar to that of single faces, while those of single faces and face ensembles diverge extensively from each other. Thus, our work capitalizes on a new center-surround paradigm to elucidate the neural dynamics of ensemble processing and the information that underpins it. Critically, our results serve to bridge the study of single and ensemble face perception.
The astronomical and calendrical calculations in the 6th Hymn de Crucifixione by Ephrem the Syrian in the old Babylonian, Jewish and Christian context
Authors: Fomicheva Sofia
Published: December 2023

The paper is focused on the astronomical and calendrical lore which the Syriac poet-theologian Ephrem the Syrian abundantly uses in his 6th hymn De crucifixione. In this hymn devoted to the interpretation of three days problem of Jesus’ resurrection, the Syriac poet and theologian employs some astronomical data, i.e., the duration of solar and lunar years, the duration of the lunar months, the necessity of the intercalations in the calendars etc. The author analyses this lore in the context of the astronomical knowledge existing to Ephrem’s epoch. On the one hand, the article pays attention to the similar use of the astronomical data in a lot of Jewish and Christian works of the 3rd and 4rd centuries. In this period the astronomical calculations have been used actively both in Christian and Jewish milieux. On the other hand, the calculations by Ephrem mirror the peculiarities of the region of the north Mesopotamia where he lived and created his works. For example, the author demonstrates that Ephrem could be influenced by the old Babylonian astronomical theory and use in his computations the Babylonian “double hour”. In the article is also demonstrated that the calculations by Ephrem are striking similar to the ones in the “Panarion” by Epiphanius of Salamis. Epiphanius seems to be acquainted with Ephrem’s works or to use the similar tradition stretching back to the Babylonian one. The author draws a conclusion that the calculations in the hymns are used to express Ephrem’s self-presentation as the scribe and the sage who obtains the cosmic “secrets”. This picture is deep rooted as in the old Mesopotamian literature as in Jewish Aramaic writings. The author points out that Ephrem uses the astronomical lore in the liturgical context and not in the theological “scientific’’ tractate. Hence, Ephrem constructs a new religious and poetic “myth” about the Crucifixion and feast of Pascha upon the astronomical dimensions it has both in the Christian and in the Jewish traditions.
Аnonymous Sogita about Abraham and Isaac (5th cent.)
Authors: Golovnina Natalia , Dmitrieva Elizaveta
Published: December 2023

The publication presents a translation from the Syriac language of the anonymousSogita about Abraham and Isaac (V century). The introductory article discusses the issue of thepeculiarities of the Syriac versification, characterizes the sogita as a liturgical exegetical genre,as well. In addition, the influence of the Jewish tradition on the structure-forming principles ofthe Sogita genre is traced, which was manifested in its dependence on the principles of narrativeexegesis. A characteristic feature of the latter is the obligatory reconstruction of the plot detailsand characteristics of the characters missing in the biblical narrative as a way to set the text theright perspective of understanding. In turn, the mutual influence of Christian Syriac andByzantine literatures is reflected not only in the set of ideas, but also in the choice of means ofrhetorical expressiveness for church preaching. The poetic form and dialogues between biblicalheroes among the Syrians were mandatory for almost all homiletic genres (sogita, madrash,memra) from the very beginning of their existence. Among the Byzantines, dramatic homiliesbegan to appear only in the fifth century, and the rhythmized prose of sermons, facilitating thetransition from the ancient metrical versification to the syllabic, gradually acquired a new poeticform for the Greeks. In the comments to the sogita, there are collections of interpretations of aparticular problem that have developed in all three traditions: Syrian, Byzantine, and Jewish,which makes it possible to clearly understand how the same exegetical methods worked tojustify solutions that differ from each other.
Christian Arabic book making in the mountains of Samtskhe: from the history of contacts between Georgia and the church of Antioch at the latter half of the 15th century
Authors: Panchenko Konstantin
Published: December 2023

The 15th century was a period of deep decline and isolation of the Rum Orthodox Church of Antioch. Nevertheless, exactly in this time contacts between the Arab Christians and Georgian lands became more intense. In 1460-s political disintegration of Georgia began. Rulers of western and southern Georgian lands strived for independence not only from political power of kings of Kartli but as well from ecclesiastical jurisdiction of Catholicos of Mtskheta and tried to find moral support from the Patriarchs of Antioch. About 1462–1464 Patriarch of Antioch Mikhail IV gave the autocephaly to the Catholicos of Abkhazia previously subordinate to Mtskheta. At the same period atabegs of south-Georgian principality of Samtskhe maintained close contacts with the Church of Antioch intending to receive ecclesiastical autocephaly of their lands from the Patriarch of Antioch. Among the evidences of these contacts there were two Arabic Christian manuscripts written in Georgian lands in 1478 and 1488 by order of Kaykhosro, the son of atabeg of Samtskhe Kvarkvare. Presumably from the very beginning these books were intended to be a donation to Sinai monastery of St. Catherine, the main spiritual center of the Christian East. Scribe who composed the first manuscript, deacon Ephrem, was prominent copyist and author of the earliest Arabic description of Mount Sinai. The second scribe Elias from Damascus was calligrapher and poet who undoubtedly belonged to elite of the Melkite intellectuals. Both scribes in one way or another were connected with Melkite community of Damascus which at that period dominated in ecclesiastical affairs of the Orthodox East.

On the stability of a characterization by the lack of memory property
Authors: Januškevičius Romanas
Published: December 2023

An useful and interesting characterization of the Weibull distribution is its lack of memory (of order α) property, i.e., P(X  ≥ (xα + yα)1/α|X ≥ y) = P(X ≥ x) for all x, y ≥ 0. The characterization holds even in the case when it is required to fulfil this relation not on the entire semi-axis {y|y ≥ 0}, but only at two incommensurable points y1 and y2. The stability estimation in this characterization is analyzed.

One of the approaches to modeling the process of blood distribution in soft tissues of living organisms
Authors: Pyanylo Yaroslav
Published: December 2023

An approach to building a mathematical model of pressure distribution in soft tissues of living organisms is proposed. Soft tissues are modeled by a porous medium that has the shape of a hollow cylinder of a certain length and radius. The movement of the fluid contained in the porous medium is described by the filtration equation undergiven boundary conditions. A numerical experiment was conducted, the results of which qualitatively coincide with real processes.

Authors: Denysiuk Orest
Published: December 2023

The main purpose of this article was to study existing image processing methods, binarization and noise reduction, and to develop an improved adaptive thresholding algorithm. The analysis of methods and tools for eliminating distortions in image and video signals is an urgent task in numerous fields, including medicine, computer vision, and document science. The article discusses in detail the existing binarization and noise reduction methods, highlighting their advantages and limitations. However, the main achievement is the development and implementation of an improved adaptive thresholding algorithm. This algorithm considers the specific features of the image and automatically adapts the binarization threshold for better processing quality. It is a significant contribution to the field of image processing and can be used in various fields, including medical diagnostics and visual object detection in images.
Hysteresis in ferromagnetic materials and its impact on electromagnetic devices
Authors: Dyriv Roman
Published: December 2023

Hysteresis is a well-known phenomenon that occurs in ferromagnetic materials when they are exposed to external magnetic fields. It results from the inherent properties of magnetic domains, which tend to align with an external field direction. However, when the field is removed, the domains do not return to their initial state but retain a residual magnetization, which leads to the formation of a hysteresis loop. This behavior can have a significant impact on the performance of electromagnetic devices, which rely on magnetic fields for their operation. Hysteresis can cause energy losses, reduced efficiency, and other undesired effects in devices such as transformers, inductors, and electric motors
Representationofcubicirrationalityusingthesumoftwoperiodicbranchedchainfractions
Authors: Fys Mykhailo
Published: December 2023

The paper creates such an algorithm that represents cubic irrationality using the sum of two periodic branched chain fractions. Theunity and convergence of these fractions are proved. It is logically assumed that the irrationalities of higher orders are directly related to the order of the algebraic equation. However, it is difficult to propose such a simple procedure for constructing the corresponding irreducible equation for the simple reason that there are no closed formulas for roots higher than degree four. And the existing formulas for the 3rd and 4th orders are not very suitable for constructing an equation that corresponds to the given irrationality. Therefore, in the future, we will propose a simple way of constructing the corresponding irreducible equation and perform the necessary research on its basis

Asthmalitis? Diagnostic Variability of Asthma and Bronchiolitis in Children <24 Months
Authors: Walsh Patrick S. , Wendt Wendi-Jo , Lipshaw Matthew J.
Published: December 2023

BACKGROUND AND OBJECTIVES

Bronchiolitis and asthma have similar acute clinical presentations in young children yet have opposing treatment recommendations. We aimed to assess the role of age and other factors in the diagnosis of bronchiolitis and asthma in children <24 months of age.

METHODS

We conducted a retrospective cross-sectional analysis of the Pediatric Health Information System database. We included children aged <2 years diagnosed with bronchiolitis, asthma, wheeze, or bronchospasm in emergency department or hospital encounters from 2017 to 2021. We described variation by age and between institutions. We used mixed-effects models to assess factors associated with a non-bronchiolitis diagnosis in children 12 to 23 months of age.

RESULTS

We included 554 158 encounters from 42 hospitals. Bronchiolitis made up 98% of encounters for children <3 months of age, whereas asthma diagnoses increased with age and were included in 44% of encounters at 23 months of age. Diagnosis patterns varied widely between hospitals. In children 12 to 23 months of age, the odds of a non-bronchiolitis diagnosis increased with month of age (odds ratio [OR] 1.13, 95% confidence interval [CI] 1.12–1.13), male sex (OR 1.37, 95% CI 1.35–1.40), non-Hispanic Black race (OR 1.54, 95% CI 1.50–1.58), number of previous encounters (OR 2.73, 95% CI 2.61–2.86, for 3 or more encounters), and previous albuterol use (OR 2.24, 95% CI 2.16–2.32).

CONCLUSIONS

Non-bronchiolitis diagnoses and the use of inhaled bronchodilators and systemic steroids for acute wheezing respiratory illness increase with month of age in children aged 0 to 23 months. Better definitions of clinical phenotypes of bronchiolitis and asthma would allow for more appropriate treatment in acute care settings, particularly in children 12 to 23 months of age.
Import Substitution and Parallel Imports in Various Regions of the World: Economic and Legal Analysis
Authors: Emelkina Irina A. , Fomina Olga N.
Published: December 2023

Introduction. Import substitution is one of the key tasks of Russian politics and the economy of recent decades, which determines the relevance of studying this concept in other regions of the world to create the prerequisites for its most effective integration in our country. Back in 2022, parallel imports in our country began to be legalized by implementing the international principle of exclusive rights exhaustion. The purpose of the work is to analyze various regional approaches to import substitution and parallel import.

Materials and Methods. The object of the study is the institutions implementing the legal regulation of import substitution and parallel imports in the Latin American, East Asian, North American and African regions, in particular the institution of exclusive rights exhaustion to trademarks, compulsory licensing, etc. in doctrinal and historical aspects. In the course of the study, an analysis of key legal acts related to the registration of import substitution policy and the legalization of parallel imports in the most representative countries of various regions of the world was carried out. The doctrines and judicial practice of some foreign countries concerning import substitution, exclusive rights exhaustion, parallel imports and compulsory licensing were studied.

Results. As a result of the analysis of the import substitution policy in various regions of the world, it was concluded that it is advisable to develop in our country our own most adequate way for introducing import-substituting practices, in particular, combining tariff and non-tariff methods of protectionist influence on the economy. The domestic concept of exclusive law is currently undergoing a stage of transformation from “pro-author” to a kind of “mixed”, giving it uniqueness and identity. The national principle is legislatively enshrined in Art. 1487 of the Civil Code of the Russian Federation, however, judicial and administrative, in particular customs practice, is already guided by the “pro-market” model, implementing the international principle of exhaustion, laid down in by-laws.

Discussion and Conclusion. We consider it expedient to form at the level of the CIS countries and other friendly states the creation of international organizations with similar functions aimed at paternally regulating the economies of the participating countries and creating optimal conditions for the implementation of the import substitution policy. The data obtained by the authors may be of practical significance for representatives of the legal, economic, business community, practicing lawyers, teachers and entrepreneurs, as well as representatives of the lawmaking initiative.
