Sources for the Study of Early Ecumenical Views of Amfilohije Radović: Justin Popović
Authors: Cvetković Vladimir
Published: November 2021

The paper aims to analyze the early ecumenical views of Amfilohije Radović with reference to the influence exerted on him by his spiritual father Justin Popović. This investigation is important because Radović’s ecumenical engagement is often a matter of controversy, which results in conflicting views. Sources for studying Radović’s early ecumenical views are: his correspondence with Justin Popović on ecumenism, his engagement in editing and publishing Popović’s book Orthodox Church and Ecumenism, and finally, his article written as a report from an inter-Orthodox conference held in September 1972 in Thessalonica. In addition to Radović’s similarity with Popović's views, the paper also aims to show their differences, i.e. their different interpretations of the same phenomena.
Metropolitan Amfilohije’s Views on St Gregory Palamas and Orthodoxy: A Return to Palamism
Authors: Athanasopoulos Constantinos
Published: November 2021

In what follows, I examine the views of Metropolitan Amfilohije’s views on St Gregory Palamas and Orthodoxy, primarily focusing on his PhD thesis, which was defended at the University of Athens, Faculty of Theology in 1973, and published in Thessaloniki in the same year. I claim that his views there not only show him defending Palamas, but also highlight the need for a strengthening of Palamism in Greece and abroad. Some of the problems, which he identified in 1973, exist in Orthodoxy today and his suggestion that all contemporary Orthodox intellectuals should persist in the Philosophy and Theology of Palamism seems to be the only way to solve these problems, even today.

Authors: Nguyen Giao Thanh
Published: November 2021

Water quality is critical for a healthy ecosystem, this study was conducted to evaluate the surface water quality in lakes in An Giang Province from 2017 to 2019. Water quality was assessed using variables of temperature, pH, dissolved oxygen (DO), total suspended solids (TSS), chemical oxygen demand (COD), biological oxygen demand (BOD), nitrate (NO3- - N), phosphate (PO3 4- - P ), ammonia (NH+ 4 - N), and coliforms at nine locationsbelonging to seven reservoirs including O Tuk Sa, Thuy Liem, Soai So, Soai Chek, O Thum, O Ta Soc, and Bung Binh Thien. Water quality criteria were assessed according to the National Technical Regulation on Surface Water Quality (QCVN 08-MT: 2015/BTNMT). Cluster analysis (CA) and principal component analysis (PCA)were applied to group water quality to identify the main parameters affecting water quality in the reservoirs. The findings indicated that the water quality in the reservoirs were polluted by TSS, organic matters (DO was low, while COD and BOD were high), and microorganisms (coliforms). The PCA analysis showed that the watervariables including temperature, pH, DO, TSS, COD, BOD, NO3- - N, PO3 4- - P , NO3- - N, and coliforms significantly influenced the surface of the water in the reservoirs. It is necessary to investigate pollution sources to propose appropriate solutions to treat and maintain the water quality in the reservoirs of An Giang Province .

Authors: Лелюх Софія
Published: November 2021

У статті обґрунтовано загальні основи організації та розробки змісту навчання в системі православного шкільництва Волині у ХІХ – на початку ХХ століття, що склалися під впливом суспільно-релігійних, соціально-політичних, соціокультурних чинників. Окреслена специфіка процесу організації та розробки змісту навчання в приходських/народних училищах Волинської губернії православним духовенством краю під впливом освітніх реформ ХІХ - початку ХХ століття. Визначено основні проблеми в організації діяльності приходських народних училищ в краї – спорадичність, неврегульованість розгортання мережі початкового парафіяльного шкільництва під опікою православного духовенства. Зміст освіти концентрувався виключно навколо вивчення основ православ`я і змісту богослужінь, з невеликим додатком у вигляді арифметики й історії Російської імперії. Реалізація такого змісту навчання цілком відповідала тій само формулі, проголошеній на початку ХІХ століття – «православ`я, самодержавство, народність». Головними чинниками такої неврегульованості визначено складнощі з фінансуванням народних училищ, проблеми із забезпеченням приладдям та елементарними підручниками, а також вчителями – представниками місцевого духовенства, що мали б належний рівень професійної підготовки до викладання у системі парафіяльного шкільництва.

Published: November 2021

У статті досліджено проблеми педагогічного менеджменту в системі освіти України. Наголошено на важливості питань управлінської діяльності та підвищенні якості професійних компетентностей менеджера.

На особливу увагу заслуговує висвітлення вимог до освіти, менеджменту та  пріоритетної ролі управлінської діяльності в навчальних закладах, реалізації головних завдань педагогічного менеджменту на засадах інноваційних стратегій та новітніх технологій, представлених у Національній стратегії розвитку освіти України.

У проаналізованих наукових працях, присвячених проблемі управлінської діяльності в галузі освіти, зосереджено увагу на тому, що саме освіті належить важливе місце в сфері професійного менеджменту, тому на зміну традиційному «управлінню» має прийти «педагогічний менеджмент», який дасть можливість більш детально висувати вимоги до фахових компетенцій керівників закладів освіти.

У статті розглядаються концепції, критерії та види освітнього менеджменту, висвітлені у науково-педагогічних дослідженнях як українських, так і зарубіжних вчених. Представлені головні завдання, що стоять перед закладами освіти, реалізуються у процесі виконання менеджерами своїх професійних навчально-виховних функцій.

У процесі дослідження проблеми педагогічного менеджменту як важливої складової системи освіти України поняття «менеджер навчального закладу» визначено як «фахівець, який має високий професійний рівень, є компетентним у різноманітних питаннях щодо організації, управління та контролю в освітньому процесі закладів освіти».

with Innovative Materials
Authors: Vershinina MG , Barsukova NK , Chumicheva OA , Nadiezhina LG
Published: November 2021

Background: It is of current importance to develop an algorithm for assessing chemical and physical safety of products for children and adolescents made with such innovative materials as organic cotton, bamboo, fibers and threads containing silver ions used for children’s underwear, materials impregnated with marigold extract for insoles of children’s footwear, and diapers from plant raw materials. The institute conducts testing and scientific substantiation of children’s goods made using innovative technologies.
Objective: To assess safety of diapers made with innovative materials (ECO-diapers).
Materials and methods: We conducted physicochemical, toxicological and organoleptic testing of 200 samples of medium size disposable baby ECO-diapers made with innovative materials.
Results: The results of chemical and toxicological tests of ECO-diapers in a model aqueous environment showed that the formaldehyde concentration in aqueous extracts of the diaper samples ranged from 0.08 ± 0.020 to 0.1 mg/dm3; toxicity index values – from 74.1 to 89.1 %; pH – from 0.35 to 0.5 units, and the total phenolic content – from < 0.005 to 0.024 ± 0.002 mg/dm3,
thus being within permissible limits. Measured concentrations of acetaldehyde, acrylonitrile, acetone, benzene, hexane, methyl and propyl alcohols, toluene, ethyl acetate, lead, arsenic, zinc, chromium were also below threshold values. Chemical testing of the samples of baby diapers in a model air environment with exposure duration of 4, 12, and 24 hours detected migration of chemicals already after four hours of exposure, which did not change following 12 and 24 hours. The value of water absorption capacity, which is one of the main indicators of functional benefit of diapers, ranged from 307.6 ± 30.8 g to 355.5 ± 35.5 g and significantly exceeded the established standard (not less than 240.0 g for medium size diapers) owing to the use of innovative materials in the production of ECO-diapers.
Conclusions: Our findings demonstrate the necessity to develop special methodological approaches to measuring breathability of ECO- and traditional diapers, to regulate smell by including this organoleptic quality criterion in the list of safety requirements, and to limit exposure duration in a model air environment to four hours.
Changes in the Method and Modes of Mobile Phone Use and Their Relationship with the Well-being in Junior Schoolchildren
Authors: Vyatleva OA , Kurgansky AM
Published: November 2021

Background: Significant changes in the methods and modes of mobile phone (MP) use in modern primary schoolchildren and insufficient knowledge of their health consequences have determined the relevance and purpose of this study.
Objective: To assess the dynamics of MP use in primary school students and its impact on children’s well-being.
Materials and methods: In 2017–2019, changes in the type of MP, modes of voice communication and mobile Internet (MI) use, and the dynamics of the health symptoms frequency were assessed in the prospective cohort study of 47 primary schoolchildren (25 boys and 22 girls) using questionnaires. MP radiation levels were measured for 23 children.
Results: During the observation period, we noted a decrease in the level of MP radiation (p = 0.002); an increase in the proportion of children using MI (from 57.4 to 85.1 %, p = 0.006) and in the frequency (p = 0.002) and duration (p = 0.01) of MI use; keeping MP closer to the body in the daytime (p = 0.01). By the end of the study, we observed an increase in the proportion of children with clinically significant symptoms (CSS) of sleep disturbance (from 23.4 to 40.4 %, p = 0.025) and anxiety (from 2.12 to 12.8 %, p = 0.043). The decrease in MP radiation levels accompanied by an increase in the frequency and duration of MI use correlated with the replacement of the “push-button” MP with a smartphone. The switch to smartphone and MI usage was associated with an increase in CSS of anxiety (p = 0.02) and difficulty falling asleep (p = 0.043).
Conclusion: The study showed that in modern junior schoolchildren aged 7–10 with a short experience of MP usage, transition to using a MP as a multimedia device is a more important factor in impairment of well-being than the duration and intensity of MP voice communication.
Analysis of Central Hemodynamic Parameters in Medical Students during
the Pre-Examination Study Period
Authors: Belyayeva VA
Published: November 2021

Background: One of the main negative factors of the educational environment is the increased stress impact on the cardiovascular system of students preparing for examinations. The cumulative effect of a long-term, systematic exposure to stressors may be accompanied by impaired mental and somatic health of students. The extent of response to stress is individual; it is usually determined by cardiovascular health and a complex of psychophysiological characteristics of the body.
Objective: To study the main parameters of central hemodynamics in medical students depending on the body mass index and adaptive potential in the pre-examination study period
Materials and methods: In spring–summer 2019, 170 medical students (young men and women aged 20.4 ± 0.3 years) with different adaptive potential of the circulatory system were surveyed during a pre-exam study period to establish their anthropometric indicators, blood pressure and heart rate and to further estimate the body mass index and the main central hemodynamics parameters.
Results: The average heart rate of students during the pre-exam study period was 85.4 ± 12.21 beats per minute. The level of metabolic
and energy processes in the myocardium was characterized as moderate with a tendency to insufficient functional capacity of the cardiovascular system (CI = 90.4 ± 1.22). Significant differences were revealed in a number of parameters un-der study depending on gender, body mass index (F = 3.99; p = 0.00890) and the adaptive potential of the circulatory system (F = 23.08; p = 0.00000).
Conclusions: In the pre-examination study period, both the heart rate and the Kerdo index among the students were elevated, which indicates the predominance of sympathetic autonomic stress. The students with tense adaptation mechanisms demonstrated higher values of certain hemodynamic parameters. The pulse pressure and the Robinson index were higher in overweight students compared to their peers with a normal body mass index. None of the students with class 1 obesity had a satisfactory level of adaptation of the circulatory system. The analysis of central hemodynamic parameters enables the assessment of tolerance of the cardiovascular system of students to the burden of learning.

How immersive virtual reality methods may meet the criteria of the National Academy of Neuropsychology and American Academy of Clinical Neuropsychology: A software review of the Virtual Reality Everyday Assessment Lab (VR-EAL)
Authors: Kourtesis Panagiotis , E. MacPherson Sarah
Published: November 2021

Clinical tools involving immersive virtual reality (VR) may bring several advantages to cognitive neuroscience and neuropsychology. However, there are some technical and methodological pitfalls. The American Academy of Clinical Neuropsychology (AACN) and the National Academy of Neuropsychology (NAN) raised 8 key issues pertaining to Computerized Neuropsychological Assessment Devices. These issues pertain to: (1) the safety and effectivity; (2) the identity of the end-user; (3) the technical hardware and software features; (4) privacy and data security; (5) the psychometric properties; (6) examinee issues; (7) the use of reporting services; and (8) the reliability of the responses and results. The VR Everyday Assessment Lab (VR-EAL) is the first immersive VR neuropsychological battery with enhanced ecological validity for the assessment of everyday cognitive functions by offering a pleasant testing experience without inducing cybersickness. The VR-EAL meets the criteria of the NAN and AACN, addresses the methodological pitfalls, and brings advantages for neuropsychological testing. However, there are still shortcomings of the VR-EAL, which should be addressed. Future iterations should strive to improve the embodiment illusion in VR-EAL and the creation of an open access VR software library should be attempted. The discussed studies demonstrate the utility of VR methods in cognitive neuroscience and neuropsychology.
Risk-based constraints with correlated uncertainties for the optimal operation of an energy community
Authors: Dolányi Mihály , Bruninx Kenneth , Toubeau Jean-François , Delarue Erik
Published: November 2021

This paper formulates an energy community's centralized optimal bidding and scheduling problem as a time-series scenario-driven stochastic optimization model, building on real-life measurement data. In the presented model, a surrogate battery storage system with uncertain state-of-charge (SoC) bounds approximates the portfolio's aggregated flexibility.

First, it is emphasized in a stylized analysis that risk-based energy constraints are highly beneficial (compared to chance-constraints) in coordinating distributed assets with unknown costs of constraint violation, as they limit both violation magnitude and probability. The presented research extends state-of-the-art models by implementing a worst-case conditional value at risk (WCVaR) based constraint for the storage SoC bounds. Then, an extensive numerical comparison is conducted to analyze the trade-off between out-of-sample violations and expected objective values, revealing that the proposed WCVaR based constraint shields significantly better against extreme out-of-sample outcomes than the conditional value at risk based equivalent.

To bypass the non-trivial task of capturing the underlying time and asset-dependent uncertain processes, real-life measurement data is directly leveraged for both imbalance market uncertainty and load forecast errors. For this purpose, a shape-based clustering method is implemented to capture the input scenarios' temporal characteristics.
Characterization of Wearable and Implanted Antennas: Test Procedure and Range Design
Authors: Berkelmann Lukas , Manteuffel Dirk
Published: November 2021

A method for measuring de-embedded antenna parameters of wearable and implanted antennas for on-body communications is presented. It consists of a tapered flat phantom in order to characterize an antenna’s general ability to excite surface waves travelling along the boundary between body tissue and free space expressed by an angular on-body antenna gain. The design offers a test zone large enough for most typical Wireless Body Area Network devices up to smartphone-size while minimizing the required amount of tissue-simulating material. The designed antenna test range is validated in the 2.4 GHz ISM-band. In order to showcase the applicability to a realistic application, different designs of antennas integrated into an implanted pacemaker are characterized by their on-body gain patterns. A comparison of their performance in in-situ path-loss measurements reveals a clear relation to the on-body gain patterns and indicates that this parameter is a suitable measure for enabling educated antenna design for on-body applications.

Authors: A Nitish , Hanumanthappa J. , S.P Shiva Prakash , Krinkin Kirill
Published: November 2021

The dynamic contexts of heterogeneous Internet of Things (HetIoT) adversely affect the performance of learning-based network intrusion detection systems (NIDS) resulting in increased misclassification rates---necessitating an expert knowledge correlated evaluation framework. The proposed generalizable framework includes intrusion root cause analysis, correlation model, and correlated classification metrics that can be generalized over any NID dataset, corresponding expert knowledge, detection technique, and learning-based algorithm to facilitate context-awareness in reducing false alerts. To achieve this, we perform experimentations on the Bot-IoT dataset---with generalized traffic behaviors from multiple existing NID datasets---employing the Support Vector Machine (SVM) machine learning and Multilayer Perceptron (MLP) shallow neural network classifiers, demonstrating the generalizability, robustness, and improved performance of the propounded framework compared to the existing literature. Furthermore, the proposed framework offers minimal processing overhead on the classifier algorithms.
Hardware Design of a Tele-EEG Device For Detection of Neurophysiological Condition
Authors: Aminaie Pouya , Aminaie Poorya
Published: November 2021

The main idea of this research originates from the patients such that
each patient with neural disorder should refer to a medical center to
check his brain’s health condition to sample his EEG signals and present
the results to a specialist for further investigation. If this process
can be done remotely by tele-medicine techniques, it will save cost and
time. In tele-medicine method, the patient can record the EEG signal
alone at home and send the results to his physician. To this end, this
research employs Bluetooth to connect the interface system to the
computer, and the patient can send the results to his physician after
saving the data. Thus, the main purpose of designing this BCI system is
to record EEG signals using a microcontroller and transmit them via
Bluetooth to a computer and mobile phone such that the signal can be
represented instantaneously in a GUI.
Neural-network fusion processing and inverse mapping to combine multi-sensor satellite data and to analyze significant features
Authors: Joshi Gunjan , Natsuaki Ryo , Hirose Akira
Published: November 2021

In the last decade, the increase in the number of active and passive earth observation satellites has provided us with more remote sensing data. This fact has led to increased interests in the field of fusion of the different satellite data since some of the satellites have properties complementary to one another. Fusion techniques can improve the estimation in areas of interest (AOIs) by using complementary information and inferring unknown parameters. However, when the observation area is large, extensive human labor and domain expertise are required for processing and analysis. Thus, we propose a neural network which combines and analyzes the data obtained from synthetic aperture radars (SAR) and optical sensors. The neural network employs a modified logarithmic activation function, unlike conventional networks, to realize inverse mapping for significant feature analysis based on dynamics consistent with its forward processing. In this paper, we focus on earthquake damage detection by dealing with the data of the 2018 Sulawesi earthquake in Indonesia. The fusion-based results show increased classification accuracy compared to the results of independent sensors. We further attempt to understand which input features are the significant contributors for which classification outputs by inverse-mapping in the data fusion neural network. We observe that inverse mapping shows reasonable explanations in a consistent manner. It also indicates contributions of features different from straightforward counterparts, namely pre- and post-seismic features, in the detection of particular classes.

Prima dei Tuchini. Fedeltà di parte e comunità nelle valli del Canavese (Piemonte, secolo XIV)
Authors: Gravela Marta
Published: November 2021

Famous for the late 14th-century revolt known as Tuchinaggio, the Canavese area, in north-western Piedmont, provides significant information concerning the relationship between lords and subjects in a longer time span. By analysing a wide range of sources (pastoral visitations, chronicles, court and notarial records, statutes), the essay examines the domini-homines dialectic in the first half of the 14th century: in the Canavese Alpine valleys various degrees of institutional consolidation of communities can be outlined, identifying a process of growth common to communities in the entire Alpine Arc.
Signorie e relazioni interstatali. Opportunità e rischi del potere locale lungo la frontiera alpina dello stato di Milano (secolo XV)
Authors: Della Misericordia Massimo
Published: November 2021

This essay analyzes the ways in which rural lordship was legitimized, maintained and sometimes contested in the late Middle Ages. The focus is not on the local societies and the political competition within the regional state, but rather on the position of seigneurial power in the interstices of international relations. Specifically, the dynamics of the frontier allowed the lords to enforce their power, but produced situations that put their authority in risk, providing opportunities for their subjects to contrast it. Political brokerage is the key to exploring the competition and the relationship between a variety of local actors and the state authorities. The source I selected is the Carteggio sforzesco, consisting of the written correspondence between these protagonists. From this viewpoint and thanks to records rich in narrative and descriptive contents, I will try to reconstruct economic tensions, military instability, the need for diplomatic agreements and for individual protection, that define the relationship between the Duchy of Milan, Valais, Switzerland and Grisons. Finally I will go into depth in the case-study of Val Formazza, where the domination of the lords family was in decline during the 15th Century, while local protagonists of this diversified local world – highlanders of lower social conditions settled in a peripheral valley forming an ethno-cultural minority of German speakers – were capable.
La signoria nel gioco politico: una lettura strutturale (area subalpina, secoli XIV-XV)
Authors: Fiore Alessio
Published: November 2021

Aim of this article is to discuss the structural role of territorial lordship for its owners in north-western Italy between the fourteenth and fifteenth centuries. Through analysis of a large number of cases, we can see that it performed different functions according to different frameworks. In particular, it was a device for reproducing the social eminence of lords compared to the rest of the regional elite. Indeed, controlling a lordship meant having a huge and stable political capital, which could however be invested in two substantially opposite strategies: in the search for substantial autonomy from state power, or on the contrary in the creation of a structural and symbiotic link with state powers.
La signoria dell’ospedale di Sant’Andrea di Vercelli su Larizzate
Authors: Olivieri Antonio
Published: November 2021

The paper examines the case of the acquisition and management of the farm of Larizzate, near Vercelli, by the hospital of Sant'Andrea of Vercelli, in a period going from the twenties of the thirteenth century to the early fifteenth century. A comparison between the data provided by the agrarian pacts and the data made available by the periodical accounts that recorded the trend of the give and take between the owner and the dependent farmers shows the discrepancy between the services due and actually paid by the hospital employees in Larizzate. An analysis of the account books reveals, on the one hand, the great importance of the work carried out by the employees for the hospital to offset the debts accrued by the former towards the latter; on the other hand, the importance of the works for the construction and restoration of the defensive structures with which the farm was equipped. These fortifications were an expression of the lordly power exercised by the institution over the population gravitating around the farm, which can also be seen, albeit in a discontinuous manner, from other sources.
La signoria di Arena in Oltrepò. I Beccaria e la forza della comunità (secoli XIII-XVI)
Authors: Covini Maria Nadia
Published: November 2021

The lordship of the Beccaria, a branch of the great family from Pavia, on Arena Po, was established at the end of the thirteenth century, taking advantage of both the financial difficulties of the small municipality and the power of the family in Pavia. It was meant to last for centuries. Managed in a consortium form by various Beccaria exponents, it encountered difficulties also in relation to the political events of the duchy. Various documents are examined to investigate the nature, modalities and reality of the relations between the lords and the land in the final centuries of the Middle Ages, especially from the fiscal, economic and agricultural point of view.

Published: November 2021

Based on the content analysis of the sources of patent and scientific literature on the biotechnology of lichens as a medicinal raw material, systematized modern information is provided, as well as original experimental data regarding the cultivation of botanical species of lichens of various ecological and geographical groups under controlled conditions. Since ancient times, lichens havebeen used as medicines and are included in the pharmacopoeias of various countries. At present, methodological approaches have been developed for the cultivation of lichens (genera Usnea, Rhinocarpon, Umbilicara ) and their components: phycobiont (genera Nostoc, Chlorella ), mycobiont ( Petrusaria pertiza, Leydea parasema, Alternaria sp.). The main biologically active compounds (usnic acid, lichenin, cetrarin, water-soluble vitamins, calcium oxalate) and the pharmacological effects caused by them (antimicrobial, stimulating appetite, enveloping, anti-inflammatory, anti-burn, regenerating). Biotechnological approaches can be implemented for species cloning, reproduction, creation of a bank of cell cultures of lichens and their components in order to preserve economically valuable producers in an active state and develop technologies for obtaining biomass and pharmacologically valuable biologically active compounds.
