Authors: Salamekh A. , Alsaid M. , Petrovsky V. A.
Published: December 2022

The description of an experimental setup for studying the durability of polymer composite materials samples which are used for the sea carrier ships superstructures manufacture is presented in the paper. The structural composition of the installation and methods of applying loads to the test sample are presented in detail. The installation includes a rocking table which simulates the rocking of the ship on which the test sample is fixed with bolted, riveted or adhesive connection methods. In this paper, an analysis of the loads affecting the walls of the superstructure is carried out. In particular, the area of the lower part connected to the main hull of the vessel during the operation of the vessel in marine conditions is analyzed. Acting loads on the test sample simulate the loads acting on the superstructures of sea vessels, in particular, on the junction of the superstructure with the main hull. During carrying out tests on this installation, it is possible to change the values of loads in accordance with the actual loading conditions of ship superstructures. The setup has a universal character and makes it possible to study the durability of samples made of polymer composite materials depending on their structural components, the number and arrangement of layers under certain loading conditions taking into account wind and wave loads as well as compressive loads that arise from the own weight of the superstructure. The calculation results of the stresses arising in the test sample under the action of the loads listed above are presented. The conclusion made proves the relevance and advantages of using the proposed installation for determining the durability of polymer composite materials and the tendency to improve it during further research.

Published: December 2022

The situation in the ship repair industry taking into account the organization of production, quality management and quality control during the ships repair is analyzed. The necessity of improving the technological processes of ship repair production is proved. It is proposed to continuously improve the production process by reducing losses arising from irrational production management. The introduction of lean manufacturing principles will significantly reduce losses. It is pointed out that it is necessary to solve the problems of providing ship repair production with modern means of non-destructive testing and complexes of new devices in order to improve the processes of quality control of ship repair work, since the improvement of means and methods of control contributes to improving the efficiency and quality of ship repair work. Conclusions that the high quality of repair work is ensured by the exact compliance with the established technology and careful consistent control, starting from the original materials and ending with the testing of finished products are drawn. The lack of preventive control functions, and therefore an active impact on quality, is the main drawback of the existing control system. It is indicated that there are such negative indicators as insufficient depth of theoretical justifications and the sequence of taking control actions, non-compliance with the basic principles of building control systems (centralization and independence of control, quantitative quality measurement, factor-causal analysis), lack of a comprehensive nature of measures and a systematic approach. In the future, it is proposed to create a quality management system that could prevent defects, and preventive control functions would allow systematically improving the quality of ship repair work.

Authors: Makarchuk N. V. , Makarchuk A. V. , Startsev V. N.
Published: December 2022

In modern shipbuilding, those enterprises and shipyards that introduce innovative and highly efficient technologies gain an advantage in the competitive struggle. The experience of the largest European shipyards, such as Meyer Werft and Blohm und Voss in Germany, Kvaerner Massa Yard in Finland, Fincantieri in Italy, shows the great potential of laser equipment in creating breakthrough technologies in shipbuilding. The leading role among the developed technologies is played by the technologies of laser and laser-arc welding. Compared to arc welding, laser and laser-arc welding increase the welding speed by 2-3 times, and a decrease in butt gaps leads to a decrease in the need for welding consumables. The approaches to creating a model for predicting the metal structure and mechanical properties of a welded joint in laser welding are discussed in the paper. This will make it possible to establish welding modes at the preproduction stage and obtain the properties of welded joints specified by the designer. This model is based on mathematical calculations of the thermal regime of welding and the process of crystallization of welds. A mathematical model of laser welding is used, taking into account the presence of a vapor-gas channel, which allows laser radiation to penetrate the entire thickness of the weld, which ensures the formation of a deep, narrow weld. The results of the calculation make it possible to determine the shape of the penetration pool and the position of the main temperature lines in the heat-affected zone. For beam welding methods, it is proposed to approximate the surface of the melt pool (crystallization front) by a cubic spline. Its main advantage is that the entire shape of the surface is modeled most accurately and completely, which allows you to build the surfaces of all areas of the bath without excluding any parts. On the basis of such a spline, the predominant direction of crystallite growth, their growth rate in the direction of welding are determined, and the integral characteristics of the emerging primary macrostructure of the weld metal are found. Based on the criteria characterizing the process of crystallization, a prediction of the macrostructure of the weld metal is given.

Published: December 2022

A method for calculating shock short-circuit currents in marine electric power systems with direct current distribution of electricity is presented in the paper. These systems are widely used in shipbuilding. The calculation of short-circuit currents in such systems has a number of features related to the operating modes of these networks. In the systems with direct current electricity distribution, the generation and consumption of electricity is carried out on alternating current, while the distribution is carried out on direct current. The current standards for calculating short-circuit currents in DC and AC systems in this case cannot be used for a number of reasons. These standards do not consider specific supply sources of short-circuit points (short circuit) and variable rotational speed of valve generators in the various operating modes. AC electric motors (ED), when they are mains powered with DC power distribution via autonomous inverters, supply the short-circuit point on the DC side. Capacitor banks and accumulator batteries connected to a system with direct current electricity distribution are additional sources for the short circuit site supply. The elements of a methodology for calculating short-circuit currents in marine power plants with direct current electricity distribution, taking into account all operating modes and additional sources of short-circuit location recharge, are proposed in the paper. A method for determining the maximum value of the shock current at the short circuit design point of the ship’s electric power system is proposed.

Published: December 2022

The sea transportation system, which in turn forms the basis of the global trade system, has been developing during the whole history of human civilization. The abrupt leaps in this steady development were caused both by the changes of technological paradigms (e. g. by the shift from sail to steam, appearance of steel framing and hull shells, containerization, digitalization etc.) and social reasons (abandon of the acceptable losses strategy after world wars, end of cold war, relaxation of the international tension and war conflicts etc.). Unfortunately, the social factors can not only push forward the development, but also have destructive character, manifesting themselves as crises of different scales and natures. The complexity and the scope of the global transportation system that has developed by the XXI century have already shown the tendency to kaleidoscopic changing of its states under small shocks. In full scale this sensitivity has developed after COVID-19 and Ukraine affairs. It seems unreal to expect not only quick revival of the collapsed world system of sea and land transportation, but even preservation of its structure. Consequently, the key elements of the transport infrastructure, i. e. sea port, found themselves in a very serious situation. Major ports have faced a problem of cargo flows deterioration and relevant redundancy of their capacity; minor ports have discovered the opposite problem, namely, the residual cargo flows squeezed on the periphery of business areal turned out to be too large for the existing facilities and resources. In both cases the changes in external commercial environment and relevant route patterns set for the ports a task of finding a new balance between potential cargo flows and existing resources. A decision of this problem by the methods of mixed integer linear programming is described in the paper.
SIMULATION MODELING OF THE SYSTEM OF RELATIONS BETWEEN THE PARTICIPANTS OF THE TRANSPORT AND LOGISTICS PROCESS AT THE SEA CARGO TERMINAL
Authors: Shapovalova Maria A. , Semenov Anton D.
Published: December 2022

In order to analyze the effectiveness of interaction of the cargo terminal operator with customs authorities and participants in foreign economic activity, a four-sector model of the network diagram of the interaction stages between participants in the transport and logistics process at the sea cargo terminal is presented in the paper; the model allows visualizing and controlling the process of aggregated relationships during cargo operations and the provision of customs services in the area of seaports activity. Calculations of works time parameters are performed on the basis of a four-sector model, in which the event is divided into four sectors, where the number of the event is indicated on the top, the early start of work is indicated on the left, the late end of work is marked in the right sector, and the number of the initial event of the previous work is indicated in the lower sector, according to which the critical path passes. At the same time, simulation modeling of the system of relations between the participants in the transport and logistics process at the sea cargo terminal is carried out. When modeling by the Monte Carlo method, a set of parametric values presented in the form of a probability distribution is used. It is noted that the operations performed in the simulation are subject to the normal distribution law, since a large number of participants are involved in the transport and logistics system. The results of the algorithm operation are presented in the form of a data array, which is a sequence of works performed during the interaction of participants in the transport and logistics process at the sea cargo terminal. One of the methods for modeling randomly distributed variables is the Box-Muller generation method. The use of the Box-Muller method in the work makes it possible to apply the fundamental law of probability transformation to obtain two independent normal variables that have a standard normal distribution. Thus, the chosen method gives a set of random numbers that have a normal distribution with zero mean and unit standard deviation. The results of simulation modeling allow us to conclude that the aggregated system of relationship between participants in the transport and logistics process, which uses the technology of preliminary declaration in order to make a decision on the early placement of goods in the inspection zone, is effective.

Authors: Ivanovskaya Aleksandra V. , Klimenko Nikolay P. , Popov Vladimir V.
Published: December 2022

The main breakdowns that may occur during the operation of the deck equipment of a fishing vessel are presented in the paper. These breakdowns can lead to devices failure, serious accidents, which, in turn, entail a decrease in the operational and economic efficiency of the ship’s auxiliary power plant and the ship as a whole. Therefore, in order to improve the maintenance system of deck equipment, it is necessary to improve the methodology for predicting reliability based on structural indicators of elements at the design stage. One of the methods for solving the task is to obtain, accumulate and statistically summarize information on the operational reliability of units, parts and equipment as a whole. For risk analysis during the operation of ship equipment, at the first stage, a classification of hazards based on available data and existing developments of technical means is required. To estimate the average resource and other indicators of the durability of ship mechanisms, it is necessary to know the parameters of the random factors distribution. This will allow, under different laws of parameters distribution, to predict the resource distribution by statistical modeling. The assessment results of the failures of the deck lifting equipment of a fishing vessel are considered in the paper. It is revealed that mooring, anchor and trawl winches, for which operating time data are given, are subject to the greatest failures. The probability of no-failure operation of parts is calculated and its graphical distribution is presented. The results obtained in this work contribute to the further continuation of research in the field of ensuring the required level of performance of elements of deck mechanisms.
PERSPECTIVE MAGNETIC NAVIGATION WITH USING THE SPLINE FUNCTIONS METHOD FOR OPTIMAL FORMATION OF THE MAP-AIDED STANDARD
Authors: Yuyukin Igor V.
Published: December 2022

An analytical review of the current problems of practical use of the planetary magnetic field as a geophysical basis for navigation is provided in the paper. A hypothesis about the possibility of orientation by an individual signature of a certain geographical area has been put forward and it is based on the fact that the Earth has a measurable magnetic field in any place and at any time, which makes the contours of abnormal magnetic intensity a reliable source of navigation. The results of domestic and foreign studies on the identification of the experimental mean square error of magnetic positioning for determining coordinates with an index of 10 m are analyzed, which in the perspective creates a precedent for supplementing magnetic navigation with the reliable backup global positioning systems. It is noted that navigation by the variable mutability of the magnetic field demonstrates a high-precision positioning potential in GPS-denied environment. As a result, the point of view of the necessity to search for an alternative method is emphasized. The actuality of creating a duplicate system is motivated by the fact that the reliability of global positioning is the subject of attention when studying the issue of cybernetic awareness for the both marine and aviation applications. The innovative approach is considered in a broad aspect, taking into account the possibility of constructing an effective configuration of an artificial neural network to remove the local magnetic field of a ship or aircraft from the measuring data of a magnetometer when using a machine learning algorithm to ensure the reliability of autonomous navigation both in near-Earth space and indoors. A three-dimensional visual representation of a digital model of a simulated magnetic field based on basic finite splines is implemented in two comparative versions: an approximated perspective of magnetic anomalies and its stylized frame model with a mathematical justification of the feasibility of using different methods as optimal standards for mapping the informativeness of magnetic positioning. The planning horizon for the incorporation of spline technology into navigation information processing has been theoretically expanded to a strategy for using a gradient approach in synthesizing the heterogeneous structure of the geophysical field in order to effectively position mobile objects based on realistic consideration of the architecture of multifactor orientation of the gradient vectors spectrum.
SPLINE MODEL OF GRIDDED DATA OPERATION AS A PRINCIPLE OF ELECTRONIC MAPPING SEABED TOPOGRAPHY
Authors: Yuyukin Igor V.
Published: December 2022

The influence of technologies of automated processing of hydrographic survey results on the potential of the human factor in the transformation of polygraphic cartographic products into digital ones is analyzed. When configuring the digital bathymetric model, the concept of the navigation surface is used as a perspective principle of automated mapping. The approach to the problem of generating bathymetric contours from measurement results in the navigation surface paradigm is construed on continuous spline interpolation of geospatial data for reasonable cartographic generalization when creating electronic cartographic products. From the theoretical positions of the spline approach, the subjectivity of the method of artificial displacement of generalized isobaths to deep-water areas is excluded when creating a safe digital model of the bottom relief, interpreted in a mathematical sense as a navigational isosurface. The principle of electronic mapping based on the use of a spline in tension as an effective approach for the process of generalizing isobaths in order to obtain a wide range of morphometric characteristics of underwater topography has been developed. The generalized line of the active depth contour is estimated in the form of algorithmic reproduction on electronic charts of the safe convexity of the isobate towards the deep-sea area due to the practical implementation of the B-spline “snake model” by analogy with the serpentine configuration of the bathymetric isoline in the form of a piecewise polynomial function. When using the spline approach, an innovative principle of electronic mapping of the underwater landscape based on operating with a set of gridded data is implemented. The latter are interpreted as the results of depth measurements with the formalization of a two-dimensional frame of fixed values of bathymetric measurements for their representation as a navigational isosurface in three-dimensional Euclidean space. The actual synthesis of the seabed topography is implemented on the basis of a proven hybrid spline model for a specific indicative test case based on the processing of experimental gridded data. Hypothetically, the possibility of intellectual assistance to the watch officer in the strategy of instant orientation in conditions of a minimum depth reserve under the keel is organized when using computer three-dimensional visualization of the topography of the underwater relief in an unaffiliated graphic environment with foreign software.
ANALYSIS OF THERMOHYDRAULIC CHARACTERISTICS OF STEAM GENERATOR CASSETTES OF THE RITM-200 REACTOR PLANTS OF THE UNIVERSAL NUCLEAR ICEBREAKERS
Authors: Korolev Vladimir I.
Published: December 2022

Currently, a new icebreaking fleet including universal nuclear icebreakers of the new generation of project 22220 is being intensively built in Russia. The nuclear icebreakers of this project such as “Arctic” and “Siberia” are already in operation. The “Ural” “nuclear icebreaker is almost ready for commissioning. “Yakutia” and “Chukotka” icebreakers as well as the icebreaker-leader of project 10510 are under construction. The integrated layout of the main equipment of the reactor plant had been used for the first time on the nuclear icebreakers of the new generation of these projects. The application of the new principle of equipment layout required switching to a fundamentally new method of forming the heat exchange surface of steam generators. As a result, straight-tube modular structures assembled into cassettes of steam generators were used. The approach to providing feed water supply and steam removal from steam generators has also changed, which significantly affects the thermohydraulic processes in the cassettes and leads to a decrease in the temperature of steam at the outlet of steam generators. In addition, the heat exchange surface of the modules in the longitudinal section forms annular channels with two-way heating by a coolant, which also affects the steam generators characteristics formation. In particular, the coefficients of heat transfer and heat transfer over the phase sections of heat exchange, the average logarithmic heat heads and the distribution of the heat exchange surfaces of the sections have changed compared to the previously used coil steam generators. At the same time, the hydraulic resistance of the flows through the working fluid and the coolant has decreased which reduces energy costs for pumping media and creates favorable conditions for improving natural circulation. In this paper, the task is to analyze the features of the thermohydraulic characteristics of steam generator cassettes, to compare them with similar characteristics of coil steam generators in operation.
Optimizing the Quality of Clinical Data in an Australian Aged Care and Disability Service to Improve Care Delivery and Clinical Outcomes: Protocol for an Agile Lean Six Sigma Study
Authors: Troeung Lakkhina , Tshering Gap , Walton Rebecca , Martini Angelita , Roberts Martin
Published: December 2022

Background

In Australia, aged care and disability service providers are legally required to maintain comprehensive and accurate clinical documentation to meet regulatory and funding requirements and support safe and high-quality care provision. However, evidence suggests that poor-quality clinical data and documentation are widespread across the sector and can substantially affect clinical decision-making and care delivery and increase business costs.

Objective

In the Optimizing the Quality of Clinical Data in an Australian Aged Care and Disability Service to Improve Care Delivery and Clinical Outcomes (OPTIMISE) study, we aim to use an Agile Lean Six Sigma framework to identify opportunities for the optimization of clinical documentation processes and clinical information systems, implement and test optimization solutions, and evaluate postoptimization outcomes in a large postacute community-based health service providing aged care and disability services in Western Australia.

Methods

A 3-stage prospective optimization study will be conducted. Stage 1 (baseline [T0]) will measure existing clinical data quality, identify root causes of data quality issues across services, and generate optimization solutions. Stage 2 (optimization) will implement and test changes to clinical documentation processes and information systems using incremental Agile sprints. Stage 3 (evaluation) will evaluate changes in primary and secondary outcomes from T0 to 12 months after optimization. The primary outcome is the data quality measured in terms of defects per unit, defects per million opportunities, and Sigma level. The secondary outcomes are care delivery (direct care time), clinical incidents, business outcomes (cost of quality and workforce productivity), and user satisfaction. Case studies will be analyzed to understand the impact of optimization on clinical outcomes and business processes.

Results

As of June 1, 2022, stage 1 commenced with T0 data quality audits conducted to measure current data quality. T0 data quality audits will be followed by user consultations to identify root causes of data quality issues. Optimization solutions will be developed by May 2023 to inform optimization (stage 2) and evaluation (stage 3). Results are expected to be published in June 2023.

Conclusions

The study findings will be of interest to individuals and organizations in the health care sector seeking novel solutions to improve the quality of clinical data, support high-quality care delivery, and reduce business costs.

The Use of Crisis Services Following the Mass School Shooting in Uvalde, Texas: Quasi-Experimental Event Study
Authors: Weitzel Kirsty J , Chew Robert F , Miller Adam Bryant , Oppenheimer Caroline W , Lowe Ashley , Yaros Anna
Published: December 2022

Background

Mass shootings result in widespread psychological trauma for survivors and members of the affected community. However, less is known about the broader effects of indirect exposure (eg, media) to mass shootings. Crisis lines offer a unique opportunity to examine real-time data on the widespread psychological effects of mass shootings.

Objective

Crisis Text Line is a not-for-profit company that provides 24/7 confidential SMS text message–based mental health support and crisis intervention service. This study examines changes in the volume and composition of firearm-related conversations at Crisis Text Line before and after the mass school shooting at Robb Elementary School on May 24, 2022, in Uvalde, Texas.

Methods

A quasi-experimental event study design was used to compare the actual volume of firearm-related conversations received by Crisis Text Line post shooting to forecasted firearm conversation volume under the counterfactual scenario that a shooting had not occurred. Conversations related to firearms were identified among all conversations using keyword searches. Firearm conversation volume was predicted using a seasonal autoregressive integrated moving average model trained on the 3 months of data leading up to the shooting. Additionally, proportions of issue tags (topics coded post conversation by volunteer crisis counselors at Crisis Text Line after the exchange) were compared in the 4 days before (n=251) and after (n=417) the shooting to assess changes in conversation characteristics. The 4-day window was chosen to reflect the number of days conversation volume remained above forecasted levels.

Results

There was a significant increase in the number of conversations mentioning firearms following the shooting, with the largest spike (compared to forecasted numbers) occurring the day after the shooting (n=159) on May 25, 2022. By May 28, the volume reverted to within the 95% CI of the forecasted volume (n=77). Within firearm conversations, “grief” issue tags showed a significant increase in proportion in the week following the shooting, while “isolation/loneliness,” “relationships,” and “suicide” issue tags showed a significant decrease in proportions the week following the shooting.

Conclusions

The results suggest that the Uvalde school shooting may have contributed to an increase in demand for crisis services, above what would be expected given historical trends. Additionally, we found that these firearm-related crises conversations immediately post event are more likely to be related to grief and less likely to be related to suicide, loneliness, and relationships. Our findings provide some of the first data showing the real-time repercussions for the broader population exposed to school shooting events. This work adds to a growing evidence base documenting and measuring the rippling effects of mass shootings outside of those directly impacted.

Authors: Tenda Priska Ernestina , Fatmawati Blegur  , Lely A.V Kapitan
Published: December 2022

Indian jujube leaves (Ziziphus mauritiana Lamk) have various potential biological activity. Previous studies have proven that ethanol extracted from Indian jujube (Z. mauritiana Lamk) leaves had analgesic activity. This study aimed to determine the total flavonoid content and analgesic activity of the ethyl acetate fraction of Indian jujube (Z. mauritiana Lamk) leaves ethanol extract. Tested fraction was prepared by maceration using ethanol as solvent followed by fractionation using ethyl acetate. Identification of active compounds was performed using color reaction, and determination of total flavonoids by colorimetric method. Ethyl acetate fraction was further tested for its analgesic activity using the writhing method. Swiss-Webster white male mice were divided into 5 treatment groups consisting of negative control contained sodium-CMC, positive control contained sodium diclofenac, while groups 3-5 were given ethyl acetate fraction of Indian jujube (Z. mauritiana Lamk) leaves with doses of 50, 150, and 200 mg/kg BW. All interventions were administered as a single oral dose. 0.7% (w/v) acetic acid was used as a pain inducer. Analgesic activity was measured by calculating the percentage of writhing protection as a measure of the analgesic effect produced by each intervention. The data were analyzed using one-way Anova to compare analgesic activity between treatment groups. Results showed that ethyl acetate fraction of Indian jujube (Z. mauritiana Lamk) leaves at doses of 50, 150, and 200 mg/kg BW gave an effect that was not significantly different from sodium diclofenac as positive control. The ethyl acetate fraction of Indian jujube (Z. mauritiana Lamk) leaves ethanol extract contained flavonoids, saponin, and tannins with total flavonoid content of 22.41 ± 1.16% w/w. It can be concluded that the ethyl acetate fraction of Indian jujube (Z. mauritiana Lamk) leaves have analgesic activity in mice.

Published: December 2022

Nowadays, with the trend of world political multi-polarization and the regional economic integration, international communication has become an essential way for the development of each country. News become indispensable to the public to acquire the information happened domestic and abroad everyday. Thus, accurate news translation based on different language backgrounds has become an important channel to get news. Give a broad overview of the current translation in China’s current situation, the research field has been expanded since the 70s of last century. However, relative researches still have a long way to go. Eugene Nida, a contemporary famous American theorist in the field of translation, his functional equivalence theory becomes a continuous improved theory which has great significance of guiding the news translation practice.This article mainly bases on Nida’s functional equivalence theory and combines with the news language features to analyze China's most representative newspaper- China Daily. By analyzing vocabulary, syntax and discourse, we could explore the application of Nida’s functional equivalence theory in guiding the practice of news translation. The study of Nida’s functional equivalence theory not only guides news translation but also instructs other translation practice. Nida’s functional equivalence theory is worthy of being studied.
Improved DIQKD protocols with finite-size analysis
Authors: Tan Ernest Y.-Z. , Sekatski Pavel , Bancal Jean-Daniel , Schwonnek René , Renner Renato , Sangouard Nicolas , Lim Charles C.-W.
Published: December 2022

The security of finite-length keys is essential for the implementation of device-independent quantum key distribution (DIQKD). Presently, there are several finite-size DIQKD security proofs, but they are mostly focused on standard DIQKD protocols and do not directly apply to the recent improved DIQKD protocols based on noisy preprocessing, random key measurements, and modified CHSH inequalities. Here, we provide a general finite-size security proof that can simultaneously encompass these approaches, using tighter finite-size bounds than previous analyses. In doing so, we develop a method to compute tight lower bounds on the asymptotic keyrate for any such DIQKD protocol with binary inputs and outputs. With this, we show that positive asymptotic keyrates are achievable up to depolarizing noise values of 9.33%, exceeding all previously known noise thresholds. We also develop a modification to random-key-measurement protocols, using a pre-shared seed followed by a "seed recovery" step, which yields substantially higher net key generation rates by essentially removing the sifting factor. Some of our results may also improve the keyrates of device-independent randomness expansion.
Quantum game theory and the complexity of approximating quantum Nash equilibria
Authors: Bostanci John , Watrous John
Published: December 2022

This paper is concerned with complexity theoretic aspects of a general formulation of quantum game theory that models strategic interactions among rational agents that process and exchange quantum information. In particular, we prove that the computational problem of finding an approximate Nash equilibrium in a broad class of quantum games is, like the analogous problem for classical games, included in (and therefore complete for) the complexity class PPAD. Our main technical contribution, which facilitates this inclusion, is an extension of prior methods in computational game theory to strategy spaces that are characterized by semidefinite programs.
Continuity of ideas of the Labor Code of the RSFSR of 1922 by Soviet and post-Soviet labor legislation
Authors: Lepyoshin Dmitrii A.
Published: December 2022

The article analyzes certain provisions of the Labor Code of 1922, which determined the vector of development of labor legislation in the period of changing political, economic and social conditions. The need for adopting the Labor Code in 1922 was caused by the transition of the Soviet state to a new economic policy. Since 1922, an accelerated process of updating labor legislation began. Some of the norms underlying the Labor Code of 1922 and the Labor Code of 1971 have been reflected and developed in the current Labor Code of the Russian Federation, e.g., the rules on terminating employment contract by parties’ agreement, differentiation in the legal regulation of labor, labor discipline, and others. The article investigates the legal position of the Constitutional Court of the Russian Federation, which had an important impact on the development of sectoral legislation, including, on recognizing part 1 of Article 392 of the Labor Code of the Russian Federation regarding the period for applying for moral damage compensation as contradicting the Constitution. Explaining the provisions of labor legislation, the Supreme Court of the Russian Federation also pays attention to the enforcement of provisions on compensation for moral damage in labor disputes. The article analyzes amendments to Article 263 of the Labor Code of the Russian Federation, allowing to conclude that those labor law norms continue to be updated.

Authors: Tumanova Anastasiya S. , Safonov Alexander A.
Published: December 2022

This article outlines a number of sources of law of various legal force that determine the legal status of non-governmental organizations in Soviet Russia in the 1917-1930s. Primarily, these are the Constitutions of the RSFSR and the USSR and Resolutions of the All-Russian Central Executive Committee and the Council of People’s Commissars on societies and unions. The authors examine doctrinal documents (resolutions of party congresses, excerpts from speeches by party leaders, etc.) that characterize self-organization of Soviet society and legal framework for the activities of mass voluntary associations. The legal foundations for voluntary associations operation in Soviet Russia, as well as specifics of legislative acts regulating their formation and activities, and the forms of control over them by the authorities, have not been fully studied in academic literature. This research aims to bridge this gap. Based on the analysis of a wide range of published sources, as well as the standpoint of modern methodology of critical legal research, the article investigates legal policy of the Soviet government aimed at developing a new legal framework for the activities of societies and unions including the principles of their relationship with the state in terms of formation, re-registration and termination of activities of mass voluntary organizations.
Social Significance of the RSFSR Criminal Code of 1922: historical, legal and humanitarian aspects
Authors: Stepanenko Raviya F.
Published: December 2022

The article examines experience and practices of the formation of the Soviet criminal legislation of the post-revolutionary period of Russia at the beginning of the 20th century and their significance for the development of domestic system of law. Attention is focused on the analysis of the norms of the General Part of the Criminal Code of the RSFSR of 1922, for the first time in the national history of state and law, which meaningfully fix social and humanistic patterns that were not previously characteristic of the criminal law normative sphere. The complexity of generating ideas and foundations of Soviet criminal law in conditions of uncertainty, multiplied by many problems of a political, socio-economic, legal, cultural, and other nature, determined the dominance of the ideological content of the introduced restrictions and penalties. On the other hand, the peculiarities of punishment system formation of the period under review should include the innovative social and humanistic orientation, which later became the basis for democratization and humanization of criminal, penitentiary, and criminal procedural law in Russia.
RSFSR Land Code of 1922 as the first codified act in the history of Russian land legislation
Authors: Yashchuk Tatyana F.
Published: December 2022

The RSFSR Land Code of 1922 (LC), adopted as part of the comprehensive codification of Soviet law in the 1920s, is in the focus of this article. The Land Code is looked at as the first codified act that forms the branch of Soviet land law, defining its subject, method, and parameters of further development. The article is based on extensive historiographical material, which is systematized by periods. In the 1920s the Code of Law was in full force, therefore, a doctrinal interpretation of its norms, and authors’ comments on the Code were published. Subsequently, the Land Code of 1922 was studied with the aim of understanding and gaining historical experience in the development of new land laws. The article uses normative legal acts of the Soviet period, published documents, and archival sources.

In modern conditions, historical and legal knowledge retains its relevance and topicality. This also applies to the monograph by A.D. Dyusyupova, devoted to the legal regulation of agrarian relations in the Russian Empire. The study is carried out on a large amount of factual material. The experience studied by the author is connected both with domestic legal traditions and modern searches for optimal ways of socio-economic development. In the context of modern global transformations, it is also extremely important to study different models for the development of adjacent and annexed territories, their inclusion into the united legal space and economic life. Therefore, the issues raised in the work of A.D. Dyusyupova undoubtedly contribute to the development of modern historical and legal science.

Sob o olhar da desconfiança: jornalistas como alvo de desinformação na pandemia da Covid-19
Authors: Rodrigues Lisboa Marcia , De Gouvêa Pereira Allan
Published: December 2022

A pandemia da Covid-19 acirrou a circulação de narrativas com informações dissonantes para embasar a defesa de posicionamentos. No Brasil, este fenômeno atingiu veículos jornalísticos, ao pôr em dúvida informações noticiadas, estendendo o descrédito aos jornalistas. Este artigo propõe-se a refletir sobre o deslocamento desses profissionais do estatuto de noticiadores da pandemia ao de noticiados, sob o olhar da desconfiança. Dois temas são centrais à discussão: a expansão do ecossistema da desinformação, em um cenário reverso da hiperinformação; e a epistemologia do jornalismo, com seus discursos normativos e práticas. Os dados para o exercício analítico foram colhidos de duas agências de verificação brasileiras no período de janeiro de 2020 a junho de 2021.
APROXIMAÇÕES ENTRE BASES NEUROBIOLÓGICAS DA MEMÓRIA HUMANA E PRESSUPOSTOS DA METODOLOGIA DIALÉTICA
Authors: Rosa Cleci Teresinha Werner da , Silva Estela Mari Santos Simões da , Ghiggi Caroline Maria
Published: December 2022

O presente artigo constitui-se de pesquisa de natureza qualitativa e bibliográfica, visando refletir sobre as possíveis relações no campo educacional entre a metodologia dialética e a neurociência cognitiva, no que diz respeito ao processamento da informação por mecanismos cerebrais humanos. O objetivo da pesquisa é mostrar os princípios neurocientíficos da memória associados às dimensões da abordagem metodológica dialética. E embora se reconheça que o ato de aprender envolva diferentes mecanismos neurobiológicos como atenção, emoções, motivação, sono e plasticidade cerebral, opta-se no artigo por estabelecer como recorte aproximações entre tipos de memórias e suas funções, com os momentos propostos pela metodologia dialética. Para tanto, apresentam-se inicialmente conceitos sobre consolidação de memórias no campo da neurociência cognitiva e os três momentos da dialética (mobilização, construção e elaboração de síntese do conhecimento). Na sequência, busca-se aproximações entre essas duas dimensões, compreendendo a primeira com uma área complementar e a segunda como uma estratégia didática direcionada à construção de conhecimentos. Por fim, evidenciam-se os sombreamentos entre os dois campos e apontam-se novas possibilidades para pensar uma neurodidática, mostrando que compreender mecanismos cerebrais envolvidos no ato de aprender surge como condição à efetivação de uma prática escolar que busca favorecer a aprendizagem.
