Orthodox educational methodology: the obsolete past or the upcoming future?
Authors: Menshikov Vladimir
Published: June 2024

The article defines the concept of pedagogical methodology as the unity of the method of cognition and the subject of cognition and analyzes the main directions of the European pedagogical methodology: ancient, Christian, New European; their essence is shown through the comprehension of the most important pedagogical categories: education, the purpose of education, the concept of a person, the process of education, including the content and technologies of education. Through the analysis of the work of A.A. Ostapenko and K.V. Zelinsky proves that the content of the main pedagogical category – the category of education cannot be the content of some theological category, which the authors take the concept of repentance. The concept of salvation cannot be such a content either. Pedagogical categories should have pedagogical content. It also explains the idea that the basic pedagogical category cannot be the category of education, therefore, as such, it is necessary to use historically the first Russian pedagogical concept – the concept of education. Based on this attitude, it is shown what is the content of the main pedagogical categories in the Orthodox methodology. It is revealed that pedagogical categories in the system of Orthodox methodology explain a person and his upbringing more accurately than in other pedagogical methodologies (ancient and New European). And therefore it is proved that the Orthodox pedagogical methodology has not remained in the historical past, but it should become the main pedagogical methodology now and in the future.
Cantatory manuscripts of Antonievo-Siysky monastery as a source for the history of Russian church singing of the 17th century (notation, text editions, styles of singing)
Authors: Grigorjeva Veronika
Published: June 2024

The Synodal Cantatory Collection of the State Historical Museum contains a complex of cantatory MSs from Antonievo-Siysky Monastery. Most of them date from the 17th century. This was the time when the Russian tradition of church singing was being actively transformed. At Antonievo-Siysky Monastery, these changes took place quite intensively, and the Siysky complex of MSs is a valuable source for the history of Russian church singing of the transitional period. All types of musical notation, known in the ancient Russian manuscript tradition of the 15th — 17th centuries, are found in Antonievo-Siysky cantatory MSs, including “double-signs” (Rus. двознаменники), as well as several pre-reform MSs with a naon edition, in which cinnabar marks of the same period as the main text are affi xed. The complex allows us to trace how the preferences of Siya’s scribes and singers in using a certain type of notation changed during the 16th — 18th centuries. According to the edition of the verbal text, Siysky MSs are divided into three groups, i.e. pre-reform, transitional, and post-reform. The variety of editions of the verbal text makes it possible to study the methods of Nikon’s editors of the Printing House (Rus. Печатный двор) and their monastic followers. The repertoire of chants found in Siysky MSs shows that Siya’s professional singers had excellent knowledge of both the cantatory heritage of the late 15th — 16th centuries and the achievements of their contemporaries from major centres of singing of that time.
Relief plates from the baptistery in Split: current issues in its study
Authors: Voronova Ariadna
Published: June 2024

The baptistery of the city of Split on the eastern coast of the Adriatic in the IX-XI centuries was built in the small temple of the Diocletian's palace, and in the XIII century a font of 12 marble slabs appeared in it, six of which are covered with carvings; the rest of the plates are the spolias of antique sarcophagi and their reliefs are cut out. As a result of many years of research of the monument, all scientists agree that the plates with carvings were taken from the altar barrier of either the Split cathedral of St. Domnius (the former mausoleum of Diocletian), or the church of St. Peter and Moses in Solin. Versions of the identification of the figures on the slab with the image of the ruler on the throne, the figure standing next to and the figure lying below make up two large groups: the sitting figure is either Christ or a some king. Most researchers are inclined to two options: Croatian king Peter Kreshimir IV (1058-1074) or king Dimitar Zvonimir (1076-1089). The details of the subsequent existence of the monument are very interesting: in the hands of the standing figure there was previously an object, most likely a scroll, subsequently removed, and the inscription on the upper field of the slab was erased. In addition, the historical circumstances of the epoch are analyzed, including the weakening of Byzantine influence in the region in the XI century with the strengthening of western influence, which led to liturgical changes reflected in the architecture. The stylistic features of the monument make it possible to attract a number of regional analogies.
The image of Pentecost in the iconographic programme of the altar ciborium of Sts Peter and Paul Cathedral in St. Petersburg
Authors: Vlasova Maria
Published: June 2024

The article is devoted to the unique monument of Peter the Great Baroque – the altar ciborium of the St. Petersburg Peter and Paul Cathedral. The study presents an analysis of the decoration of the ciborium (1722-1729, I.P. Zarudny). First of all, the connection of the iconographic and iconological program of the monument with the circumstances of the apostolic dedication of the cathedral of the new capital of the Russian Empire in the context of the church reform carried out by Peter I is traced. The synodal reform is proposed to be considered from the point of view of the principles of the structure of the ancient Church as a justification for the transition from patriarchal governance in favour of the conciliar Most Holy Governing Synod.In the article, the altar canopy of the Peter and Paul Cathedral is compared with the baldachin of the Assumption Cathedral of the Moscow Kremlin, with the imperial coronation baldachins of Catherine I and with the baldachin of D.L. Bernini from Saint Peter's Basilica in Rome. The external imitation of the European fashion for baldachins was perceived as an embellishing decoration, which didn't prevent the continuation of the Moscow tradition of church decoration in the St. Petersburg monument, and the preservation of its archetypal relationship with the Jerusalem temple. Thus, the semantic connection of the royal and Divine thrones, laid down in the early Byzantine period, continues until the beginning of the XVIII century. It has found its artistic interpretation, including in the composite monogram crowning the Cathedral of Peter and Paul, the variant of interpretation of which is proposed by the author. The theme of the kingdom in the decoration of I.P. Zarudny's ciborium is intertwined with the theme of apostolic succession and the foundation of the church. The apostolic dedication of the Peter and Paul Cathedral was embodied in the artistic solution of the entire altar composition, for which the image of the "Descent of the Holy Spirit on the Apostles" became central. The establishment of a new Church and a new Jerusalem, manifested in the image of "Pentecost", indicated a particularly important role for the new state symbolically denoting its continuity from both the artistic tradition of Byzantium and the tradition of the Western Christian world.
Old Testament translations in the Grand Duchy of Lithuania and their contexts
Authors: Kavaliūnaitė Gina
Published: June 2024

From the 15th century onwards, the Grand Duchy of Lithuania was a multiconfessional and multicultural state. Apart from Lithuanians, its population comprised Ruthenians (the ancestors of Belarusians and Ukrainians), Poles, and smaller Jewish, Tatar, and Karaim communities. After its Christianization, Lithuania officially fell under the jurisdiction of the Roman Catholic Church, but most of its inhabitants were of the Eastern Christian rite. Reformed Protestantism spread among the nobility at the turn of the 16th and 17th centuries, while Lutheranism flourished in Lithuania Minor. Smaller ethnic groups also had their confessional communities. All confessional groups had their sacred books. This article gives an overview of Christian vernacular translations of the Old Testament that were read in the Grand Duchy between the 15th and the 18th centuries. It briefly discusses the circumstances of the translation of the Old Testament into Ruthenian (the Skaryna Bible), Old Church Slavonic (the Ostrog Bible), Polish (the Brest, Nesvizh and Gdansk Bibles) and Lithuanian (the Bretkūnas, Chylinski and Quandt Bibles) as well as their characteristic features.

A further speaker moved to Trakai and stayed there for the rest of her life with her sister. Thanks to favorable circumstances all of them could communicate in their daily life in Halich Karaim and maintain their full competence in their community language. Common to them all was their concern about the future of the language and their strong determination to transmit their linguistic competence to others, and especially to the younger Karaim generation.
Mykolas Firkovičius (1924–2000) and his work as a unique basis for the Karaim language revival
Authors: Firkavičiūtė Karina
Published: June 2024

This article presents the contribution of Mykolas Firkovičius (1924–2000) to the revival and continuation of the Karaim language through three strands of his activities: religion, poetry and the language itself. Mykolas Firkovičius was a native speaker of Karaim, Karaim community leader in Lithuania for many years and officially served a senior priest in 1993–2000. Among other works, he published texts in Karaim, sources, poetry compilations, prayerbooks, textbooks, and wrote himself in Karaim. He was a man that profoundly helped his nation to continue its cultural and linguistic life after disastrous times that interrupted Karaim legacy, changed and transformed it. He provided plenty of material to be used by those who want to survive as Karaims, to still speak the language, and to stay strong rooted in the traditions.
Belarus’ Sovereignty in Question: Assessing its de facto Sovereign Status in the Shadow of Russia
Authors: Molis Arūnas , Pastorello Sara
Published: June 2024

The paper explores state sovereignty by developing a systematic framework for categorising states based on their sovereignty status. At the heart of our analysis lies the distinction between sovereign states and satellite states – a distinction that has significant implications for global security, stability, and the balance of power. While sovereign states exercise full autonomy and control over their affairs, satellite states often find themselves in a subordinate position, heavily influenced or even dominated by external powers. A theoretical framework deconstructs the concept of sovereignty into four crucial elements: authority, legitimacy, independence, and territoriality, which provide a structured assessment of the level of sovereignty in a state and serve as the basis for our analysis. To illustrate the application of our framework, we adopt a case study approach focused on Belarus. As a nation situated at the crossroads of Eastern Europe with a history marked by geopolitical contestation and strategic manoeuvring, Belarus provides a compelling context for examining sovereignty dynamics. Through a systematic analysis of Belarus’ political, economic, and military landscape, we seek to assess its sovereignty status within the framework of our analysis. While the topic of Belarus’ sovereignty and integration within Russia has been extensively explored over the years, the innovative contribution of this paper lies in purposefully designed methodology for sovereignty assessment and the use of the latest empirical data while practically applying the model for the case of Belarus.

Published: June 2024

Dynamic geometry environment allows us to investigate geometric relationships and problems more efficiently than the pencil-and-paper method. Continuous variation of geometric configurations shows the relationship from different points of view. This paper aims to provide some indications
of how a dynamic geometry environment, especially GeoGebra software, can be used to offer insight and support understanding of geometry problem solving and proofs through investigation and experimentation. Our case studies show in particular how prospective teachers of mathematics deal with
difficult geometry problems, designated initially to mathematically gifted students for competition, using investigation in GeoGebra. We attempt to reveal the prospective teachers' consideration systematically when they are solving a geometric problem. The prepared visual explanation and visual
proof steps serve as clues or scaffolding to facilitate geometric problem solving, and they can be useful also for mathematics teachers in preparing their students for mathematics competitions.

Published: June 2024

ABSTRACT Dasheen mosaic virus (DsMV), a Potyvirus, and a Potexvirus (herein tentatively named Caladium virus X, CalVX) were found naturally infecting Caladium bicolor (Araceae) with chlorotic and necrotic spots and rings. Electron microscopy observations from infected leaves revealed cytoplasmic cylindrical inclusions, induced by DsMV, as well as masses of elongated particles and virus-like particles scattered in the cytoplasm. In Gomphrena globosa foliar cells experimentally infected by CalVX, electron-dense crystalline inclusions, without elongated particles, were also present in the cytoplasm and nucleus. Complex inclusions which consisted of a central, stained faint yellow area surrounded by groups of dense, olive-green stained, bodies were frequently observed in epidermal cells when stained with calcomine orange-luxol brilliant green combination. These inclusions correspond to a cytoplasm region rich in vesicles, ribosomes, scattered virus-like particles and large virus aggregates.

MEASUREMENT OF BASIC HEMODYNAMICS DURING MULTIPOST TRANSCUTANEOUS EXTERNAL EAR STIMULATION: A TWO-CASE STUDY
Authors: Rozman Janez , Miklavec Katarina , Rozman Ingrid , Emri Anja , Mirković Tomislav , Ribarič Samo
Published: June 2024

The objectives of the investigation were to assess the short-term responses of the cardio-vascular system on the multipost transcutaneous stimulation (tANS) of the external ear (EE). The scope was to measure the forefinger photopleths (FPPG), toe photopleths (TPPG), aortic phonocardiogram (APCG), mitral phonocardiogram (MPCG) and brachial arterial blood pressure (BABP), assuming that they could be altered with the tANS. For the tANS, stimulator, two silicone ear plugs with four platinum electrodes each, and a large common electrode (CE), were used. Trials were carried out with two female volunteers, aged 25 years and 28 years. To capture the heart sounds, two customized electronic stethoscopes (transducers) were used. BABP was measured using a pressure transducer and blood-pressure appliance. To measure the FPPGs, a pulse oximeter and SpO2 finger clip were used. To measure the TPPGs, another pulse oximeter and customized SpO2 foot clip was used. Signals were gathered using a high-performance data-acquisition system. An offline analysis was made just before and just after the start of the tANS. To record the pulsations in the right brachial artery, the 2D ultrasound mode (B) of the ultrasound device was used before and during the tANS. Then, diagrams showing the vein cross-sectional area over time were constructed. The results show that vascular time intervals between heart sounds S1 and S2, captured as APCG and systolic peaks of the FPPG in the second volunteer, were slightly larger during the separate tANS of the left white (LW) and (RW) EE post than before the tANS. Furthermore, vascular time intervals between the heart sounds S1 and S2, captured as MPCG and systolic peaks of the TPPG in the second volunteer, were slightly smaller during the separate tANS of LW and RW EE post than before the tANS. Finally, tANS of the LW post elicited a slightly lower heart rate than the one measured when LW was not stimulated. In contrast, the tANS of the RW post elicited a slightly higher heart rate than the one measured when RW was not stimulated. It was also shown that the pattern of the vein cross-sectional area over time with tANS was different compared to both the FPPG and TPPG.

Authors: Kralj Jernej , Hanželič Blaž , Glodež Srečko , Kramberger Janez , Satošek Roman , Nečemer Branko
Published: June 2024

The plate heat exchanger (PHE) is a component that provides heat to be transferred from hot water to domestic cold water without mixing them with high efficiency. Over the lifetime of the PHE, cyclic pressure acts on the brazing points and the plates, and this may lead to fatigue failure. The fatigue behaviour of the PHE, designed by using copper-brazed 316L (also known as 1.4404) stainless steel, was investigated by performing fatigue tests to obtain the S-N curve of the analysed brazed joint. The fatigue tests have been performed on the Vibrophore 100 testing machine under the load ratio R = 0.1 for different values of calculated amplitude stress. Based on the obtained experimental results, an appropriate material model of the analysed brazed joint has been created, which was validated with numerical calculation in the framework of a program code Ansys. A validated material model can then be used for the subsequent numerical analysis of PHE.
INVESTIGATION OF THE BENDING BEHAVIOR OF INC625/SUS316L LASER-CLADDING LAYERS APPLIED TO GGG40
Authors: Altuncu Ekrem , Tarım Melih
Published: June 2024

Laser cladding is a multi-purpose thermal coating technology whose application area has increased rapidly in recent years. It can be used for the purposes of obtaining a thick (mm to cm) layer on surfaces by the interaction of different materials in powder form (especially metallic and metal-matrix composite) with the laser beam, thus repairing, restoring, improving and protecting the surface resistance of various industrial metallic parts. It is normally used to refurbishment, create and repair metallic components, hydraulic mills, gears, shafts, turbine blades, drilling tools, and other static or dynamically loaded mechanical parts. The benefits of laser cladding over alternative technologies include better metallurgy (bonding, hardness or lower porosity) as well as reduced part deformation and stress due to lower overall heat input. The melting of substrate material ensures a good metallurgical bond between the cladding layer and the substrate material. However, the melting of the substrate material causes dilution. Therefore, the melting of the substrate material should be controlled and kept to a minimum because high substrate melting causes an increase in the dilution, which may degrade the mechanical and corrosion properties of the clad layer. The laser beam over the substrate materials creates temperature gradients in the thickness direction that can lead to mechanical deformation (such as bending) and changes in the microstructural and interface properties. Depending on the substrate type and production history, as well as the laser-clad powder properties and process parameters (power, feed rate, clad speed etc.) used in the application, the deformation properties of the cladded part and its bending behavior can change.
In this study, INC625 and SUS 316L+INC625 clad layers were applied on a GGG40 substrate with optimized parameters and then subjected to bending tests. Bending-test results were examined comparatively and their microstructural properties were examined. Cladding powder feedstock material properties, substrate type and its thermo-physical properties, clad process parameters and surface preparation conditions, number and thickness of layers are the most important factors affecting the bending behaviour in laser-cladding applications and require optimization studies. The INC625 clad layer on the SUS316L bond layer has reduced the diffusional effects, and the hardness distribution has a more homogeneous profile. In this way, an increase in bending angles was observed. The highest bending angle of 32° was measured with dublex-clad layered samples.

Published: June 2024

In the construction field, mild steel is using as reinforcement in concrete, which can easily corrode and destroy the environment. So, the construction industries are focusing on alternate materials like natural and synthetic fibres for sustainability. In this study bamboo, glass-fibre bars were used as reinforcement and compared with a normal reinforced concrete slab subject to static and cyclic incremental loading conditions. According to this, the experimental studies were carried out on 9 slab elements of size 600 mm × 450 mm with different forms of reinforcement. The slab elements’ deflection, deformation, load-carrying capacity, stress, strain, crack patterns, stiffness and energy absorption were determined and compared. The ultimate load-carrying capacity of elements like conventional, GFRP and bamboo are 28.90 kN, 29.31 kN and 5.50 kN respectively; similarly, deflection 12.70 mm, 13.50 mm and 8.60 mm were found under static load. In the same way, the ultimate load-carrying capacities of the elements are 24.23 kN, 25.00 kN and 6.80 kN under cyclic loading conditions; deflections of 10.10 mm, 13.50 mm and 3.60 mm, respectively, on conventional, GFRP and bamboo elements. From the test results the stress, strain, energy absorptions were calculated and compared and the energy absorption of bamboo was 9.38% less than conventional and GFRP was 22.49 % higher than conventional elements. The study proved that GFRP material has a significant impact than conventional and bamboo elements and the bamboo reinforcement can be used in light-loading conditions.
CONDUCTOMETRY ANALYSIS – BENEFICIAL METHOD FOR DETERMINING THE CHEMICAL COMPOSITION OF ALKALINE SILICATE SOLUTIONS
Authors: Kalina Lukas , Bílek Vlastimil , Flídrová Michaela , Markusík David , Topolář Libor , Fládr Josef
Published: June 2024

The study deals with the methodology for determining the chemical composition of alkaline silicate solutions. Nowadays, the most widely used method in industry is titration, using the color change of an acid-base indicator. This technique is very accurate for the determination of the total alkalinity (i.e., Na2O, K2O, or Li2O). However, a problem arises in the determination of the SiO2 content, since the color change of the methyl red indicator is very slow and therefore the equivalence point is unclear. The main aim of this work is to present the benefits of conductometric titration, where the equivalence point is indicated by a sudden change in the conductivity. The applicability of the method was verified with other analytical techniques, such as ICP-OES and gravimetric analyses. Their results confirmed the values of the obtained silicate module (the molar ratio of SiO2 and alkaline oxide) in the cases of sodium, potassium and lithium water glasses. Based on the obtained results, one can say that conductometry is a very promising method providing an accurate, fast and instrumentally undemanding chemical characterization of alkaline silicate solutions, usable even in a manufacturing process.

Published: June 2024

Based on SVET technology, the corrosion tendency of HRB400 steel welded joint and its base metal in simulated concrete environment and the influence of corrosion products were studied in this paper. The results show that the microstructure of the weld metal and base metal are ferrite+pearlite, and the microstructure of the heat affected zone is incompletely transformed bainite+ferrite+pearlite. Since the region produces smaller grains and more grain boundaries after welding, it becomes the most prone area for corrosion of welded joints. The addition of Cl– inhibited the passivation of HRB400 steel welded joint in the simulated concrete pore fluid. Through the analysis of Nyquist curve and polarization curve, it was found that under high chloride ion concentration, the base metal is more sensitive to chloride ions compared to welded joints.With the increase of Cl– concentration, the current density in the welded joint area gradually increased, but after reaching the chloride concentration of 0.5 mol/L, the current density tended to be flat. The occurrence of this phenomenon confirms the above conclusion. Further more,through SVET testing of the filler metal, it can be found that the filler metal has good adaptability to the HRB400 welding joint, forming a welding joint with better performance.

Titanium alloys have many applications in aerospace, nuclear and automotive industries and in most parts are in sheet form and require joints of high integrity to meet the design requirements and achieve reliable welds. For weight and cost reduction, the technology of tailor-welded blanks (TWBs) is a promising technology in various components. TWBs are usually semi-finished metallic sheets made of different strengths, materials, and/or thicknesses and a forming process is often needed to manufacture the final components. In this paper, Grade-2 and Grade-5 titanium alloy sheets (Ti-TWBs) were laser welded and subjected to a forming process in U-profile geometry at elevated temperatures. The deformation behaviors of the weld joints after forming process were analyzed by mechanical tests such as tensile and hardness tests. The formability of the welded blanks is assessed based on variations in the geometric changes related to the springback angles. The results showed that there was significant increase in tensile strength with forming temperature increase and the failure mode was changed at 850 °C. The formability of the Ti-TWBs was found to be strongly dependent on the applied process temperatures and forming at 850 °C leads to the lowest springback angle.
МЕЖДУНАРОДНОЕ ПРАВО В СФЕРЕ УСТОЙЧИВОГО РАЗВИТИЯ: АСПЕКТЫ МЕДИАПРАВА
Authors: МАММАДРЗАЛИ Шахин Сабир

Фрагментарный характер международного права, преследование жизненно важных национальных интересов и наличие конфликтующих международных политических блоков свели к минимуму эффективность права на международном уровне, усложнили будущее устойчивого развития стран мира и углубили цепочку неравенства между нациями. Эти трудности побудили ученых предложить пересмотреть саму природу нынешних бюрократических институтов международного права и начать изучение нового правового поля — международного права устойчивого развития, чтобы противостоять пагубным вызовам с целью проложить путь для развития всех правовых сфер. Хотя нормативная база международного права устойчивого развития в основном состоит из несистематизированных норм «мягкого права», у нас есть Повестка ООН на период до 2030 г., Нью-Делийские принципы и отчеты о деятельности Комиссии международного права ООН, в которых прямо подчеркиваются роль медиаправа, права журналистов, свобода выражения мнений и информации, свобода интернета и доступ к нему. Тем не менее недостаточно научных работ о важности положений медиаправа для целей устойчивого развития, и существует настоятельная необходимость взглянуть на международное право устойчивого развития с точки зрения норм медиаправа.
ИНТЕЛЛЕКТУАЛЬНЫЕ СИСТЕМЫ РАСПОЗНАВАНИЯ ОБРАЗОВ И СМЫСЛА В СИСТЕМЕ ПРЕДУПРЕЖДЕНИЯ ПРЕСТУПЛЕНИЙ
Authors: ЖАРОВА Анна Константиновна
Published: June 2024

Интеллектуальные системы (ИС) являются наиболее перспективным направлением развития информационных технологий, важность применения технологических решений ИС в экономике и общественных отношениях заявлена в правовых актах. Однако мы сталкиваемся с ситуацией, когда информация, например, размещенная в интернете и содержащая намерение совершить преступление, не выявляется, что приводит к реализации преступником своих преступных умыслов. А ведь возможности некоторых алгоритмов искусственного интеллекта вполне могут быть использованы уполномоченными органами обеспечения безопасности в системе предупреждения преступлений. Это, к примеру, алгоритмы глубокого обучения, предиктивной аналитики больших данных, распознавания смысла и образов и другие.
К сожалению, в открытом доступе отсутствуют отчеты о результатах применения методов предиктивной аналитики больших данных в системе предупреждения преступлений на территории Российской Федерации. Однако есть много зарубежных отчетов о применении алгоритмов искусственного интеллекта (ИИ) в целях предотвращения преступных действий. Возможно, такая ситуация связана с различными подходами к пониманию понятия «преступление». В связи с этим в статье изучены аналитические материалы, в которых отражен опыт применения алгоритмов ИИ в целях определения вероятности отнесения выявленных противоправных действий к преступным на основе соотнесения признаков преступления; осуществления преступления конкретным человеком на основе анализа его криминогенных качеств, а также в целях выявления преступного умысла и оценки вероятности его перехода в преступные действия.

To evaluate the effectiveness of 2 artificial saliva formulations, sodium carboxymethylcellulose artificial saliva spray and sodium carboxymethylcellulose artificial saliva spray plus β-glucan.

: This study was a double-blind randomized controlled trial and involved older adults with xerostomia. The xerostomia inventory score, clinical oral dryness score, oral moisture degree, unstimulated salivary flow rate, and salivary total antioxidant capacity were measured prior to and after treatment. The results were evaluated 4 weeks after taking both products.

: The study included 51 subjects in the control (n = 25) and BG (n = 26) groups. xerostomia inventory score and clinical oral dryness score were significantly lower in both groups after 4 weeks of treatment (p<0.00). Additionally, both groups had significantly greater oral moisture degree and unstimulated salivary flow rate than before treatment (p<0.05). Only the increase in oral moisture degree in the BG group was significantly greater than that in the control group (p=0.048). Both groups tended to have decreased salivary total antioxidant capacity, but only the control group had a significant difference at 4 weeks (p=0.004). There was no significant difference in satisfaction score between the two groups. No serious side effects were found in the study.

: The clinical signs and symptoms of xerostomia were improved by both control and artificial BG saliva. BG improved oral moisture more than the control. Furthermore, BG was more likely to prevent a decrease in salivary total antioxidant capacity than was the control.
El poder en las ciencias sociales: una revisión preliminar
Authors: Cajas Guijarro John Wilfrido
Published: June 2024

El artículo explora los rostros del poder en diversas ciencias sociales, como la sociología, la ciencia política, la relaciones internacionales, la filosofía y la economía. El texto explora la complejidad del poder, subrayando diferentes facetas que incluyen las interacciones entre individuos, las restricciones impuestas a esas interacciones, la influencia en la configuración de sus intereses y construcción de su identidad. Estas facetas se manifiestan en distintas esferas, como las dinámicas cotidianas, los mercados, las relaciones de clase y las interacciones en la economía global. Como conclusión, se subraya la importancia de comprender estas perspectivas como una forma de contrarrestar las narrativas que sugieren la “ausencia de poder” en ámbitos, cuando en realidad el poder está omnipresente, aunque pueda se antoje etéreo.
Pro-Environmental Behavior of Visitors to National Parks in India: Role of Recreation Involvement and Environmental Activism
Authors: Maidullah Sana , Kumar Jeetesh , Bhat Iqbal Ahmad , Mandić Ante
Published: June 2024

This study investigates the impact of recreational involvement and environmental activism in forming pro-environmental behavior in tourists visiting national parks. The objective is to understand how tourists spend time with nature and their level of environmental contribution to their willingness to adopt pro-environmental behavior within the National Park. In addition, it aims to examine the mediating role of environmental satisfaction between tourists’ pro-environment behavior and their place attachment. Based on the theory of Place Attachment, which asserts that humans form feelings of association with specific locations, the authors intend to understand how tourist attachment to the national park affects their attitudes and actions related to the environment. Visiting a national park is a recreational involvement for tourists, allowing them to sense responsibility toward the environment. In addition, environmental activism is featured as an individual involvement to protect the environment. Three hundred and fourteen national park visitors in India participated in the current study. WarpPLS (7.0), a variance-based structural equation modeling (SEM), was used to test the research model. By revealing the factors impacting pro-environmental behavior in a national park in India, findings provide an understanding to the national parks authorities in designing interventions and education programs that promote recreation involvement and environmental activism to foster sustainable tourist behavior toward conservation and preservation of national parks in India.
