Development of the hydrocarbon resources of the Russian Federation continental shelf is the largest infrastructure project. Unique explored oil and gas reserves simultaneously represent a complex science-intensive technical task associated with the offshore geological exploration, well drilling, production, and transportation of the hydrocarbons. Article discusses technical solutions proposed by the authors for the safe development of the Kamennomysskoye-Sea and Semakovskoye gas fields located in the shallow waters of the Ob and Taz bays of the Kara Sea. According to the results of engineering-geological surveys and marine electrical exploration, it is established that the frozen soils are widespread on the banks of the bays and partly in the water area at a distance of up to 100 m from the coast. Construction and operation of the gas wells and offshore pipelines in the Arctic zone are associated with complications caused by the formation of thawing halos in the near-wellbore space and the soils of gas pipelines foundation. As a result, near-mouth subsidence of soil, deformation of structures and piping of wells, collapse of the coastal slope in the area of gas pipeline landfall are possible. In order to avoid these negative phenomena and improve the operational reliability of engineering facilities, new technical solutions are proposed, the use of which will improve the industrial and environmental safety of expensive projects. As such solutions based on the numerical thermal engineering modeling, the following is proposed. Creation of an ice-ground cantilever due to the joint operation of thermal stabilizers and heat-insulated lift pipes in order to reduce the thermal effect of gas production wells on the host soils. This will allow to reduce the distance between the wellheads, ensuring safety and reducing the cost of backfilling multi-well pads. Local thermal stabilization of soils at the base of gas pipelines is possible with the use of thermal stabilizers installed with a certain step, the size of which is determined by the results of heat engineering, deformation, and strength calculations.

The article is devoted to the study of the applicability of expert assessment methods for analyzing the vulnerability of production and technological processes at the petrochemical industry facilities in the event of equipment failures leading to a malfunction of the object. Justification is given concerning the need for an expert assessment procedure for identifying the combinations of failures of the production process in case of failure of specific elements of the process flow diagram. Examples are given related to the use of expert methods for predicting the risks of hazardous events and calculating possible consequences for the population, the environment, and the state as a whole in the event of an accident using methodological recommendations for risk analysis developed by Rostechnadzor. Enterprises, in particular, of the petrochemical profile, need methods, the use of which will make it possible to reasonably develop more advanced preventive measures to counter potential threats. Each combination of failures corresponds to its own array of diverse initial data, including the results obtained using the Event tree analysis and Failure tree analysis methods, the results of calculations of damage indicators, economic indicators, expert assessments in determining the «weights» of the criteria when finding production vulnerabilities of the technological process. The choice of a priority scenario is based on such methods as the Reduced Hierarchy Analysis method, Full Hierarchy Analysis method, multicriteria optimization — the shifted ideal method. It is proposed to improve the possibilities of using the method for determining scenario of an emergency considering a comprehensive assessment of the values of indicators of a set of criteria in order to identify the most vulnerable combination of failures and measures to ensure industrial safety.
Locating the southern boundary of the East European Platform within the north-western Black Sea shelf according to gravimetric data
Authors: Kozlenko M.V. , Kozlenko Yu.V.
Published: September 2022

The work is devoted to the problem of determining the position of the border of the East European Platform (EEP) and the Scythian Plate (SP), which is of great economic importance in dividing the north-western shelf of the Black Sea into more and less promising areas for hydrocarbons. An analysis of the allocation of the juncture of EEP and SP using 23 literature sources published from 1985 to 2020 was performed. The essential differences in drawing the relevant line by different authors are shown. A method for determining the position of the southern boundary of the EEP within the north-western shelf of the Black Sea is proposed, based on the integrated use of gravimetry data — characteristic features of the gravity field (Δgf.a.) and the results of systematic two-dimensional density modeling. The outcome of modelling allowed determining the position and nature of the EEP and SP junction in the section of the earth’s crust, which turned out to be a transcrustal fracture of the southern falling with angles of inclination from 83.5° to 85.5° in different parts of the shelf. According to calculations of the exit points of the faults on the basement surface superimposed on the scheme Δgf.a made it possible to identify the spatial position of the junction of EEP and SP and its extension outside the modeling area for the entire study area. It is established that this line has a zigzag character, changing direction at the intersection with submeridional faults. It is shown that the formation of the southern boundary of EPS was controlled, except for the submeridional component characteristic of EPS, by three other systems — latitude, directions NE-SW and NW-SE, which are observed for tectonic elements of SP in Pridobruzha and Crimea. The correctness of the determination of the boundary position by gravimetric data is confirmed by the results of seismic stratigraphy and thermometry previously obtained by other researchers.

In this work, the dependence of the friction and wear behaviour in dry-lubricated steel-bronze contact on the dry lubricant used and on the substrate material (steel or bronze) under constant load was investigated. For this purpose, a block two-disc test rig was used, with the dry lubricants PA66-PTFE-cb as blocks, which were produced via chemical bonding (cb) of polyamide 66 (PA 66) and radiation-modified polytetrafluoroethylene (PTFE). The results provide a good basis for the selection of a suitable dry lubricant and the counter body for the transfer of the dry lubricant in dry lubricated worm gears consisting of a steel worm and a bronze wheel.

Rolling-sliding contacts, such as the tooth flank contact, are tribological systems whose properties are determined by the interactions between the contacting bodies, the lubricant and the ambient medium. Innovative manufacturing processes are being used to reduce friction and increase the load-carrying capacity of highly loaded rolling-sliding contacts. For mixed friction conditions, bowl-shaped structures in particular, generated for example by laser machining, have led to improved running behavior. Similar to laser machining, machine hammer peening (MHP) also produces a deterministic surface structure that can exhibit improved tribological properties. In recent years, MHP has been used specifically to optimize the service life of highly stressed tools, e.g. in deep-drawing processes, and has been developed further in a targeted manner. In this report, the rolling strength of machine-hammered surfaces is evaluated using fatigue tests on a disk-on-disk test rig gear-typical contact conditions. The MHP can be used to increase the contact strength in a targeted manner, whereby the selection of the process parameters during surface hammering represent an important influencing factor. In particular, the surface can be pre-damaged by excessive impact energy as a result of the ram stroke.

Published: September 2022

This study aims to identify and describe the translation of Indonesian cultural terms in the film Battle of Surabaya. It did not intend to pinpoint the exact translation technique used. The animated history of Indonesia and the variety of the language used in the movie, such as Dutch, English, Japanese, Indonesian, and local, motivated the researcher to conduct the research. The research method used mixed-method and translation theory as a ground theory for analyzing the data. The analysis found that 24 vocabularies contain Indonesian culture-each cultural term spread in every aspect. Socio-culture found 17 data or 71% of the total existing data; Material culture only found 1 data, Ecology 3 data, Organization 2 data, Gesture or habits also 1 data. The difference in translating cultural terms was only to equate equivalence in meaning between ST and TT. Bringing cultural aspects in various ways is the same as appreciating a culture, but the way to show it and transfer it becomes a challenge for the translator. The true meaning of a cultural term may not be fully conveyed due to a lack of data or only communicated to each other in a cultural group. It can be solved if the cultural term has a glossary and the translator uses it. This study also found that foreign cultures that have been in the local culture for too long can grow and become part of the local culture itself.

Studies on taunting in video game context tend to mull over around how players taunt other players via online chat features. Studies on how taunting works in games with in-game taunt features are under investigated. Examining twenty-seven gamestory-wise and gameplay-wise games, we argue, through this sociolinguistic study, that taunting designed for game characters is better termed ludic taunting since it has different functions from that of taunting in games with online chat feature and in real life. Ludic taunting has two major functions namely narrative and mechanical. The former which refers to taunting for game story-bound purposes is classified into archetyping, cameoing, and mythopoesing. The latter, for game play-bound purposes, is classified into buffing, cosmeticizing, cueing, debuffing, hinting, and rewarding. Game designers and scholars could employ this study as a reference in designing games with in-game taunt features.

Authors: Rahayu Mundi
Published: September 2022

The current paper examines the Native American people's identity, especially the main female character's cultural identity in the short story entitled The Search Engine. Sherman Alexie, the author of the story, is a Native American writer who harnesses the Indian identity as one of the main topics. The identity presented in the main character, Corliss, shows the challenges of the stereotypes of Native American girls. For that reason, the paper aims at exploring the new Indian woman’s cultural identity represented in the main character, Corliss, in the short story The Search Engine. The study applies feminist literary criticism that enables the writers to deeply explore the issue of woman's identity among the American native people. The main character, Corliss, shows the new female image identity, in which she can challenge traditional stereotypes of Native American women. Corliss is represented as a highly literate woman, with a lot of reading on English literary works, and has concern on her Indian-ness, which is often incommensurable to her big family’s views. The main character shows the new female image of an Indian girl evidenced in her excellent literacy and attitude toward Indian and White people. She has new consciousness in seeing the Indian men and women and their relation to White people.

Published: September 2022

Argyrodites are a class of compounds united by a similar structural motif. Typical for argyrodites is the coexistence of rigid anionic and disordered cationic sublattices. Due to this, argyrodites exhibit a wide range of properties. This work is devoted to the development of the single crystal growth regime of high-quality single-crystalline samples of Ag7PS6, which belongs to the compounds with argyrodite structure. The initial Ag7PS6 alloy is obtained from high purity elementary components by a two-step and one-temperature method. The maximum synthesis temperature was 850°C. The obtained alloy was investigated by DTA and XRD methods. The congruent melting of Ag7PS6 (Tmelt = 801°C) and the structural phase transition P213 → F-43m at a temperature of 271°C was confirmed. The study of the phase composition established the synthesized alloy is single-phase. The growth of Ag7PS6 was carried out by the directional crystallization method from the melt. The growth regime of Ag7PS6 was selected taking into account the nature of the thermal behavior of the compound based on DTA data. As a result, the grown Ag7PS6 single crystal of ~ 40 mm long and 12 mm in diameter was obtained. According to the results of XRD, it has been established that the grown Ag7PS6 single crystal is single-phase and crystallizes in a primitive cubic cell with lattice parameters of 10.3917 Å.

Experimental studies of excitation of thymine, guanine, cytosine, uracil, which are the basis of the biological structure of DNA and RNA, contribute to the study of the mechanisms of their destruction under the influence of low-energy β-radiation and ultraviolet radiation. Crystal chemical analysis of the structure of the cytosine molecule showed that it exists in two crystalline forms that crystallize in orthorhombic syngony, but in different space groups (form Cyt (I) – Pccn (56) and Cyt (II) – P212121 (19)). The crystal structure of cytosine (form Cyt (I)) is formed by repeating fragments consisting of two parallel chains, each of which forms three cytosine molecules. Parallel chains are connected by hydrogen bonds formed between the N atoms of the amino group of one molecule and the N heterocyclic ring of another N–H¼N molecule (1,897 Å). The individual fragments are perpendicular to each other (along the x-axis and the y-axis) and are connected by hydrogen bonds of the N amino group and the O carbonyl group of the N–H¼O (2.158 Å). Linear chains of cytosine molecules (form Cyt (II)) are located along the y-axis and are connected by single cytosine molecules of adjacent chains by hydrogen bonds N–H¼O (2,127 Å). Chains are formed from cytosine molecules that are connected by hydrogen bonds N–H¼O (2.153 Å) and N–H¼N (1.898 Å). Ab initio quantum chemical calculations of the electronic structure using the Quantum Espresso (QE) software package based on density functional theory (DFT) showed that Cyt (II) is characterized by a direct conductivity type, band gap Eg=3.52 eV, crystal cell energy Ecrys= –571.81 Ry, energy per atom E/at= –142.95 Ry, Fermi energy EFermi=2.67 eV. The optical band gap (Eg) of cytosine Cyt (II) is formed by electron transitions N 2p(O 2p) → C 2p(N 2p).
PARTIAL CATALYTICAL PROPANE OXIDATION ON ALUMOSILICATE CATALYSTS
Authors: Dzyamko V.M.
Published: September 2022

In the scientific literature the problem of obtaining highly selective aluminosilicate catalysts is related to the study of the influence of the nature of active centers (acidity of their surface) on the catalytic activity. In some cases a linear dependency can be observed between the rate of acidity and catalytical activity. The acidity of alumosilicates, in its turn, is considerably dependent on the mode of their preparation. In case of preparing alumosilicates by joint precipitation with the increase of Al2O3 rate from 0.1 to 1.0% the concentration of acid centers increases in proportion with aluminum oxide contents. With further increase of aluminum oxide rate the concentration of acid centers increased more slowly whereas at Al2O3 rate of 75% the concentration of acid centers decreased. In this work physical and chemical properties of five alumosilicate catalysts with different content of aluminium oxide in them are synthesized and analyzed. The reaction of propane oxidation by air oxygen was investigated to define the influence of alumosilicates’ active centers on the catalytic process. In all specimens of alumosilicates the reaction products were as follows: formaldehyde, acetic acid, CO, CO2, C3H6, H2, H2O, as well as acetic aldehyde were found in small amount. At high (above 770 K) temperature CH4 and C2H4 were found. The possibility of obtaining of formaldehyde and acetic acid with high selectivity is demonstrated. The catalysts’ activity in the reaction under study accounts for aluminium oxide in their content the acidity of the surface. A suggestion is made about the possibility of the formation of formaldehyde and acetic acid on different active centers of the catalyst. On the basis of the research and relevant literature a scheme of propane oxidation on alumosilicate catalysts is proposed.

Published: September 2022

One of the wound treatments was negative pressure wound therapy (NPWT), which used wound dressings on the wound bed to ameliorate wound healing. Unfortunately, most wound dressings were two dimensional (2D), lacking the ability to cover severe wounds with a straightforward procedure. The sheets needed to be stacked following the wound curvature, which might be problematic since improper stacking could hinder the wound healing. Regarding the mentioned problems, our group develops 3D wound dressings, which are made using 3D printers. The wound dressings are made of polycaprolactone (PCL), polyurethane (PU), and polyvinyl alcohol (PVA). As the initial stage, the mechanical integrity of the soft polymers was investigated under uniaxial tensile and uniaxial compressive stress using computational methods. The polymers were defined as 3D lattices following the dimension of existing wound dressings. Based on the simulation results of displacement and von Mises stress, the three polymers are mechanically safe to be used as wound dressing materials.

Published: September 2022

The patient from the Asian region always demanded a fully functional knee implant, which implied a high-flexion range of motion. Most of their daily life activities utilized the deep knee flexion which flexed until 165° such as the Japanese proper sitting style and Muslim prayer position. The problem of the study is extending the range of motion or achieving the high flexion of total knee replacement as the traditional total knee replacement was incapable to achieve more than 115°. Hence, the purpose of this study is to achieve a modified design of a knee implant that can flex up to 165° by carried out a static structural analysis in the ANSYS R16. There are 0°, 90°, 135°, and 165° angles of flexion with a different net force based on the percentage of body weight implemented on the knee implant. The analysis includes total deformation, Von Mises stress, shear stress, and contact pressure on knee implant were observed and compared to find better modification design. The total deformation had been decreased by about 69% at 0° flexion, 58.5% at 90° flexion, 90.93% at 135° flexion. The contact pressure also had been decreased by about 99.2%, 22.2%, 99.98% at angle flexion of 0, 90, and 135, respectively. The same declination happened to von Mises stress at about 85.05%, 9.52%, and 88.04% at the same angle of 0, 90, and 135, respectively.

Published: September 2022

Adsorption Cooling System gives an alternative to the commercial vapor compression refrigeration cycles due to their benefits of having a very environmentally friendly and promising energy-saving system. An adsorption cooling system consists of four main components which are thecondenser, evaporator, expansion valve, and adsorption bed for the system to effectively function. One of the factors that affect the efficiency of the system is the performance of the evaporator itself as the system operates at sub-atmospheric pressure and the performance is mediocre when using conventional evaporators. Due to the low-pressure condition, hydrostatic pressure may affect the saturated temperature of the water refrigerant in a flooded type evaporator. Therefore, in this study, the performance of the evaporator was investigated based on the water height variation. The highest heat transfer coefficient and evaporation heat transfer rate are achieved when the water is set at the heat exchanger tube diameter level. Furthermore, 0.1 kg of silica gel adsorbent is used to obtain the maximum of 250 W/kg of Specific Cooling Power when the heat transfer fluid is set to 20 ºC.

Published: September 2022

The fibre behaviour is a critical aspect that will determine the deformation of the composite since it highly relies on its physical and chemical properties. This paper focus on the effect of similar fibres aspect ratio (L/D) with different length of untreated Kenaf fibre and SodiumHydroxide/silane treated Kenaf fibres on the flexural properties of the composites. The treated and untreated kenaf fibre at two different fibre lengths (A: 0.4 cm and B: 2.9 cm) were fabricated at low filler loadings (5,10,15%) and high filler loadings (45,50,55%). The results showed an improvement in the flexural stress (7-44 %) and modulus (6-46 %) with the application of treatments for both A- and B- fibre categories. The optimum result was achieved from the treated samples at a shorter A-fibre composite, although the aspect ratio between A and B-fibre samples are similar. The chemical treatment coalition might improve the surface interaction and, at shorter fibre length, it affects the fibres compact-ability that led to an improvement in stress distribution and low voids formation as supported by the observation on the composite's fractured surface where traces of matrix observed on the surface of pull-out fibres. From the fractographic analysis, the fibres morphological condition before the fabrication is one of the important factors to consider since it can affect the end-properties of the composites.

Published: September 2022

Piezoelectric materials have found their parts in numerous manufacturing applications such as transducers and sensors. Piezoelectric material shows anisotropy; in addition, its elastic field and electric field are integrated. The analysis of piezoelectric materials has obtained great interest among researchers with the development of smart structures. It is significant to explain the distribution of stress and electric displacement fields along the bonded edge. It has never been obvious how stress singularity and electric displacement fields are distributed at the vertex of piezoelectric dissimilar material joints. Stress and electric displacement distribution near the vertex along the interface of piezoelectric boned joints are investigated in this present research. Numerical analysis of piezoelectric dissimilar material joints is carried out by using Abaqus FEA software. From the numerical analysis, it is observed that stress, displacement, electric potential, electric displacement field evolvement along the interface edge rises with the increment of adhesive layer thickness and slant angle. So, a thin adhesive layer thickness and small slant angle are more reliable for operation.

Published: September 2022

Dissimilar metals welding using shielded metal arc welding (SMAW) has been widely used in various industries such as automotive, maritime, transportation, and offshore structures. In this work, the Taguchi approach was applied for improving the tensile strength of dissimilar welding between AISI 4340 steel and 304 Austenitic stainless steel. The effects of four welding factors: electrode type, welding current, joint type, and welding speed on the tensile strength were studied. The various factors were assigned to an L9 orthogonal array, and analysis of variance (ANOVA) was utilized to determine a significant contributing factor. It was found that electrode type and current welding factors significantly affect tensile strength. The optimum condition parameters for tensile strength were achieved with an electrode type (E309), welding current (110 A), joint type (II), and welding speed (2 cm/min).

Entre los hallazgos puede mencionarse que la experiencia iniciada en el contexto por covid-19 supuso transformaciones en las relaciones laborales y en los procesos de cuidado, lo que produjo disrupciones y cambios en las prácticas familiares, donde persisten desigualdades de género, limitaciones para el desarrollo laboral, imperativos, preocupaciones y malestares con impacto diferencial en las mujeres. El artículo aporta a considerar el trabajo sostenido por docentes-madres como una actividad que, pese a no haber sido considerada esencial, no admitió discontinuidades y ello tuvo consecuencias en los arreglos familiares. Analizamos de este modo la estructura sexual y generizada de los cuidados, la cual se ha visto intensificada en momentos de pandemia, aunque no ha implicado mayores márgenes de reconocimiento.
Consideraciones en torno al concepto de cine experimental
Authors: Jacobsen Camus Udo
Published: September 2022

El concepto de «cine experimental» es quizás uno de los más difíciles de definir, pero también de reconocer. Aquello que denominamos de este modo responde a acercamientos epistémicos y fenoménicos diversos. Este concepto aglutina, de este modo, una serie de prácticas creativas y fenómenos de recepción diversos. Nos proponemos aquí delimitar algunos criterios que sirvan para acercarnos a una definición más precisa que nos permita identificar con mayor claridad una película experimental.
¿Qué deviene el Cine?
Authors: Berti Agustín
Published: September 2022

La reciente obra de Pablo Martín Weber ha tenido un impacto notable en el circuito de festivales y museos del cine. Este artículo analiza sus films, realizados a partir de la manipulación digital de archivos audiovisuales utilizando procedimientos experimentales. Para ello, se parte de una revisión de preguntas clásicas de la teoría del cine como la ontología de la imagen fotográfica de Bazin o el cine como escritura de Astruc, y discusiones más recientes sobre el found footage y el cine de base de datos, a la luz de debates sobre la estandarización, la gubernamentalidad algorítmica y la visión maquínica para abordar la tecnicidad inherente a la poética (y la política) de Weber.
El mundo rasgado. Una poética del cine
Authors: Mutchinick Melissa
Published: September 2022

Reseña a Gustavo Fontán (2021). Maraña/Escritos sobre cine. Ciudad autónoma de Buenos Aires, VerPoder. 127 páginas.

«Una película que interrogue al mundo solo puede ser un balbuceo», reseña la contratapa del libro de Gustavo Fontán, Maraña/Escritos sobre cine (2021). Un balbuceo que permita vislumbrar la experiencia de la rasgadura del mundo, aunque el cine pocas veces haya querido asimilarla. Lo rasgado nos da cuenta de un mundo en tensión, azaroso e incomprensible, lo que se manifiesta de imprevisto en un instante fugaz. Cómo filmar la experiencia de esta rasgadura es de los que nos habla Fontán en este libro.
In Search of a New Methodology of Social Regulation and of Knowledge of Law: About Convergent Technologies and Aesthetics of Law
Authors: CHERNOGOR Nikolai , EMELYANOV Alexander , ZALOILO Maksim
Published: September 2022

Modern law falls into an “aesthetic” crisis, which must be considered as an expression of the structural crisis of law at the moment of its transformation from the state of a self-regulating system to a self-developing system. Postmodern law needs new legal patterns, which would allow returning the ease of perception of law and the beauty of the formulation of its prescriptions. In this regard, a revision of the methodology of social regulation and of knowledge of the law is required. The starting point is an appeal to the aesthetics of law. The final result is determined by the technological level.
The objectives of the study are to establish the possibility of expanding the methodology of cognition of law through the methods of aesthetics and convergent (NBICS) technologies, as well as to determine the nature and extent of their influence on the methodology of social regulation.
The introduction of aesthetic methods in the context of the development and implementation of NBICS technologies will allow us to establish the regularities of the genesis of law and the legal order, which will determine the main directions of overcoming the modern structural crisis in law.

Authors: KHITARYAN Davit , STEPANYAN Lusine , OGANYAN Kadzhik , OGORODNIKOV Vladimir , OGANYAN Karina
Published: September 2022

The article deals with the essence of abstract humanism through the identification of the main principles of synergetic historicism. It is argued that the process of self-organization of mankind is revealed through the implementation of the mechanism of the concept of the synergetic mind. The regularities of the development of social self-organization through a harmonious “synergistic person” are considered. The mechanism for realizing the ideal of synergetic humanism in reality with the help of social progress as an increase in the degree of confrontation between social chaos and social order (freedom and responsibility) is revealed.

Authors: GEVORGYAN Srbuhi , KARAPETYAN Vladimir , ISPIRYAN Mariam , DALLAKYAN Alla
Published: September 2022

The aim of the research is to reveal the distribution of psychological attitudes (preferences) of risk specialists according to the structural-operational components of the activity, to reveal the expression of social-psychological attitudes of self-confidence observed in specific situations with six-month changes, to review the connection among needs, situations and unconscious actions. Structural similarities of a person’s dispositional behavior and psychological attitudes are considered by us in terms of requirement, situation and unconscious actions. In a given social situation, the content of a person’s specific requirements can be significantly different depending on the specific role of the person. The psychological attitudes of professionals are mostly expressed in official activities, when a task arises to give preference to some structural-functional component (“motive-goal-action-result”). The analysis shows that changes in the social attitudes of professionals in the professional field related to the new situation and over time did not have a significant impact on the whole group. Meanwhile, the data of each participant has been changed to some extent.

Published: September 2022

The research contained in this work is aimed at actualizing the problem of forecasting the sustainable development of society and the state in the conditions of multifactorial socio-political turbulence observed in the modern world. The stated provisions and conclusions are intended to draw attention to the need to increase the effectiveness of cognitive activity in relation to state-organizational reality through logical and rational tools associated with the development of an appropriate dynamic self-organizational model of the object under study.
The article, appealing to the synergetic methodology, expressing the basis of the post-non-classical scientific paradigm, contains an analysis concerning the issues of the ontology of modelling of human-dimensional systems; modelling of crisis states of socio-political systems; program formula of the dynamic model of the state system.
The article substantiates the position on the fundamental possibility and importance of carrying out interdisciplinary design and research activities in the state-legal sphere, using methods of mathematical modelling and computer programming, thereby ensuring an increase in the quality of social engineering, predictability and functionality of the system of the state organization of society.
Moral Consciousness as the “Voice of Conscience” in I. Kant’s Religious Philosophy
Authors: KHASUEV Aslanbek , KAPUSTINA Darya , NEDOSUGOVA Anastasia , ZABOLOTSKAIA Irina , SHAFAZHINSKAYA Natalia
Published: September 2022

The notion of “conscience” is one of the most ancient components of the axiological sphere, the central factor of a person’s moral consciousness. The phenomenon is closely linked with the features of the ontological status of man in the world. The authors present the concept of conscience in the philosophical and religious tradition and examine the key ideas of Immanuel Kant’s religious philosophy in connection with moral consciousness as the “voice of conscience”. The idea of heterodoxy and contradiction between Immanuel Kant’s religious philosophy and Christian religious and philosophical tradition is substantiated.
Creativity Phenomenon in the Context of Medieval Christian Philosophy
Authors: URALBAEVA Sholpanay , NATAEVA Zalina , KORTUNOV Vadim , KAPUSTINA Darya , KOTOVCHIKHINA Natalia , SOMOV Denis
Published: September 2022

Based on the analysis of fundamental worldview principles of the leading medieval philosophers – Aurelius Augustinus and Thomas Aquinas – the conceptual principles of the phenomenon of creativity in Medieval literature are established. It is concluded that human creativity in the medieval Christian paradigm is associated with the divine, manifesting as salvation through union with God. In medieval Christian philosophy, creativity is not just a person’s action but also the appearance of a chance for a particular person to accept the new ontological status due to gravitating towards God and the Absolute.
