Supply Chain Response during the COVID-19 Pandemic: A Multiple-Case Study
Authors: Díaz Pacheco Raúl Antonio , Benedito Ernest
Published: April 2023

This study explores the responses of manufacturing and service provision companies in Santiago de Cali to stimuli during the COVID-19 pandemic. The responses included changes in demand, absenteeism, and the development of new products, which affected the supply chain (SC). The qualitative methodology of the multiple-case study was used. The evidence for the multiple-case studies was collected through semi-structured interviews, where the interviewees were SC experts from four manufacturing companies and one service company. The data analysis was performed in two phases. In phase one, the case study protocol was completed, and in phase two, thematic analysis was used to identify supply chain response (SCR) patterns. The results revealed two aspects of the SCR. First, to respond to a stimulus, SC adapted activities other than those of suppliers and manufacturers, such as product design and development, human resources, budgeting, and logistics. Second, the SCs used several alternatives to respond to the stimuli. This study contributes to two aspects of the SCR literature: (1) it documents the identification, detection, planning, and evaluation of SCR in response to a stimulus, and (2) it proposes the concept of the response alternatives. The response alternatives concept facilitates decision-making and resource management in SCR.

Published: April 2023

Design parameters such as initial bonding section, prestress, and bonding stiffness have a significant impact on the mechanical properties of the full-length bonded prestressed bolt. In order to understand the influence of the above three parameters on the axial force and shear stress of anchor bolts under the condition of rock separation, theoretical and numerical models were established, and the sensitivity of different parameters was analyzed based on the grey correlation method. Results indicate that the bonding stiffness had the greatest impact on the mechanical properties of the bolt and largely determined the peak axial force, peak interfacial shear stress, and number of sliding elements. Moreover, prestress had a significant impact on the peak axial force and the distribution of shear stress in the initial bonding section, while the length of the initial bonding section had a significant impact on the number of sliding elements and the peak axial force after sliding. The grey correlation method results show that the correlation degrees of the initial bonding section, prestress, and bonding stiffness were 0.8932, 0.9023, and 0.9775, respectively.
Modified Whale Algorithm-Based Optimization for Fractional Order Concurrent Diminution of Torque Ripple in Switch Reluctance Motor for EV Applications
Authors: Saha Nutan , Mishra Prakash Chandra
Published: April 2023

This work proposes a new multi-objective optimization technique for concurrent diminution of torque ripple with the regulation of the speed of a 75 Kilowatt, 8/6, 4-phase SRM based on a double close loop, modified whale algorithm optimized fractional order proportional integral (MWAO FO-PI) control with a commutation angle controller. The system is analyzed and designed in MATLAB/SIMULINK environment. First, the performance of MWAO is tested on 30-dimensional standard benchmark functions. It is found that MWAO performance is better when examined on 30-dimensional standard benchmark functions, compared with WOA, and another six recently proposed state-of-art functions. Then, a double loop control based on the MWAO FO-PI controller is designed and implemented for concurrent diminution of torque ripple with the regulation of the speed of a 75 Kilowatt, 8/6, 4-phase SRM with a commutation angle controller. It was found that the percentage improvement achieved in the combined objective optimization function with the MWAO FO-PI controller was 10.044% in comparison with the MWAO PI controller, and 9.0597% compared with the WOA PI controller. It is also proved that MWAO FO-PI-based double close loop control of SRM provides less torque ripple, better tracking of speed with a reference value of speed and a better current profile in comparison with the MWAO PI controller and WOA PI controller. From all the above analysis, the conclusion is reached that the MWAO FO-PI controller provides very good overall system operational performance compared with MWAO PI and WOA PI controllers. The conclusion is reached based on simulation analysis and experimental validation is lacking.

Authors: El-Sebaey Mahmoud S. , Ellman Asko , El-Din Sh. Shams , Essa Fadl A.
Published: April 2023

The main objective of this research was to create two different configurations of a flat-plate solar air heater, namely, Conventional-Case A and Modified-Case B, and develop a three-dimensional computational fluid dynamics (CFD) model using ANSYS R15.0. The purpose of the CFD model was to simulate the heat transfer behavior of the proposed solar air heaters under unsteady conditions. The RNG k-ε turbulence model was employed for this CFD study. The experiments were conducted on sunny days, under the same conditions as the Egyptian climate. The results of the experiments show that the simulated CFD model and the measured outlet airflow temperatures, relative humidity, and velocities of the two tested solar air heaters were compared. The developed model made very satisfactory predictions. Moreover, the deviations between the average CFD outlet air temperatures and the experimental results were 7% and 7.8% for Case B and Case A, respectively. The CFD-simulated average relative humidity was reduced by 31.6% when using Case B compared with Case A, and it was reduced by 28.8% when comparing the experimental data to Case B. Additionally, the average CFD thermal efficiencies obtained for Case B and Case A were 28.7% and 21.6%, respectively, while the average experimental thermal efficiencies for the cases were 26.4% and 18.2%, respectively. The proposed model can be used to design and simulate other solar air heater designs.

Published: April 2023

Liquid–liquid equilibrium (LLE) data are critical for the design and optimization of processes for extracting aromatics. Partial LLE data for the non-aromatic–aromatic–sulfolane ternary system were acquired at 313.15 K and 101.3 kPa. The LLE data for the extraction of aromatics using sulfolane were predicted using the COSMO-RS model. Correspondingly, the predicted and experimental data were analyzed using the root mean square deviation (RMSD), distribution coefficient (D), and separation factor (S). The COSMO-RS model could better predict the LLE data for the extraction of aromatics by sulfolane. The results of quantum chemical calculation show that hydrogen bonds and van der Waals interactions between sulfolane–benzene and sulfolane–toluene were responsible for the strong selectivity of sulfolane for benzene and toluene over alkanes. The LLE data predicted by the COSMO-RS method using the UNIQUAC thermodynamic model were subjected to correlation analysis. The calculated RMSD values were all less than 0.0180, and the relative deviation (δ) between the simulated value of the main process index for the extraction column and the actual data was less than 2.5%, indicating that the obtained binary interaction parameters can be reliably used in designing and optimizing the extraction of aromatics using sulfolane.

Published: April 2023

Pistacia lentiscus is an evergreen shrub widely used in folk medicine due to the high biological potential of the leaves’ phenolic compounds. Since phenolic compounds are susceptible to degradation under different heat, light and oxygen conditions, various microencapsulation techniques, such as spray drying, can be used to increase their stability. The objective of this study was to examine the influence of different carriers (gum arabic (GA), maltodextrin 13–17 DE (MD), β-cyclodextrin (BCD) and their mixtures), carrier concentrations in feed (12.8, 16 and 19.2% (m/V)) and drying temperatures (120, 150 and 180 °C) on the physiochemical properties, total phenolic content (TPC) and antioxidant activity (AOA) of Pistacia lentiscus leaf extract powders. Product yields of powders ranged from 23.53 to 65.51%, moisture content from 2.89 to 12.03%, hygroscopicity up to 4.45 g/100 g, solubility from 27.11 to 86.84% and bulk density from 0.24 to 0.45 g/mL. All obtained powders had satisfactory physicochemical properties, except BCD powders, which resulted in the lowest product yield, solubility and bulk density. However, BCD powders and those produced with GA containing mixtures retained the highest amounts of TPC and AOA. Thereby, the carrier mixtures with GA at a concentration of 19.2% and dried at 150 °C are recommended as the most suitable for the production of encapsulated Pistacia lentiscus leaf extracts with desirable physicochemical properties, rich in phenolics and with high antioxidant activity.
Research on the Failure Mechanisms and Strength Characteristics of Deeply Buried Mudstone under the Interaction of Water and Stress
Authors: Liu Yuedong , Wang Dongpan
Published: April 2023

Mudstone is a widely occurring type of rock in deep mining, and it is crucial to understand its failure mechanisms and strength characteristics under the interaction of water and high stress to ensure the stability of deeply buried engineered mudstone. In this study, the composition and the structure of mudstone were obtained, and triaxial tests were conducted on mudstone under five different water contents and four different confining pressures using a triaxial servo press. The variation rules for the peak strength and residual strength were obtained, and the applicability of the strength criteria was analyzed through fitting. The results showed that both the peak strength and the residual strength decreased linearly with increasing water content, with the peak strength decreasing more rapidly. Both the peak strength and the residual strength increased with increasing confining pressure, with the residual strength increasing more rapidly. The decrease in strength was primarily due to the decrease in cohesion, with the cohesion of the peak strength decreasing from 8.40 MPa to 0.94 MPa and the cohesion of the residual strength decreasing from 1.75 MPa to 0.82 MPa. The internal friction angle did not change much, with the internal friction angle of the peak strength decreasing from 41.57° to 37.29° and the internal friction angle of the post-peak strength increasing from 32.35° to 33.28°. For dry and low-water-content mudstone, the peak strength conformed to the Mohr–Coulomb criterion, while for mudstone with a higher water content, the peak strength conformed to the Hoek–Brown criterion. The residual strength conformed to the Hoek–Brown criterion. Under low and medium confining pressures, water played a dominant role in the damage pattern for the fractures produced by the initial damage to the mudstone. Under a high perimeter pressure, water played a guiding role for the fractures produced by the initial damage to the mudstone.

Published: April 2023

This work focused on the insufficient or excessive pressure relief in large-diameter pressure relief by drilling. The influence of large-diameter pressure relief by drilling on the 6307 working face of the Tangkou coal mine on the roadway deformation was taken as the research background, with numerical simulations, indoor experiments, and on-site applications used. The influence of pressure relief drilling on roadway deformation was studied to propose segmented reaming pressure relief. The influences of parameters (e.g., reaming diameter, reaming depth, and borehole spacings) on the evolution characteristics of segmented reaming cracks and pressure relief were further investigated. The results showed that segmented reaming pressure relief reduced the roadway deformation and the peak elastic energy of coal in the impacted hazard area and improved the energy accumulation of the surrounding rocks of the roadway. The effect of segmented reaming pressure relief was positively correlated with the diameter and length of the reaming section; it was negatively correlated with borehole spacings. The optimized segmented reaming parameters of the 6307 working surface of Tangkou coal mine are as follows: the optimized reaming diameter of 240 mm, the reaming section depth of 15 m, and the borehole spacing of 1.6 m. Field tests proved that the optimized segmented reaming technology can improve the deformation of the surrounding rocks of the roadway and construction.

Authors: Yang Hailu , Huang Xiaohui , Ye Zhoujing , Wang Linbing , Sun Fengyan
Published: April 2023

The purpose of this paper is to study the actual dynamic load characteristics of a full-scale Accelerated Pavement Test (APT) device called Natural Environment-Automatically Loaded Track (NE-ALT) during its operation. The NEALT uses hydraulic and support reaction forces to apply axle loads, which are somewhat different from real trucks. Therefore, in order to ensure the accuracy of the loading parameters of the device, it is necessary to analyze the dynamic load characteristics of the device during operation. In this paper, a virtual prototype model of the device was established, and the important parameters, including vehicle speed and axle load, were set. The dynamic axle load, dynamic load coefficient, and influential factors of the NE-ALT were analyzed using the model at different speeds, hydraulic pressures, and road roughness. The results have shown that the dynamic axle load accuracy was most affected by speed, followed by road roughness, and then hydraulic cylinder pressure. Compared with the real truck, its dynamic load stability was better than the real truck due to the restriction of the guide rail in the acceleration loading system and the method of hydraulic loading, and the larger the load, the more stable the load, which was different from the real truck. Therefore, in the design of accelerated pavement loading experiments, the dynamic axle load characteristics of equipment need to be considered. The results of this study can provide guidance for the further improvement and application of the NE-ALT.

Knowing the attitudes and behaviors of nursing students in relation to vaccination is important because they will soon be determinant for the health literacy of the population. Vaccination remains the most effective response in the fight against communicable diseases, including COVID-19 and influenza. The objective of this study is to analyze the attitudes and behaviors of Portuguese nursing students with regard to vaccination. A cross-sectional study was carried out, with data collection from nursing students at a university in Lisbon, Portugal. A sample of 216 nursing students was obtained, representing 67.1% of the students enrolled in this university. What stands out from the results of the questionnaire “Attitudes and Behaviors in Relation to Vaccination among Students of Health Sciences” is that for the majority of students the answers were positive; in addition, 84.7% had a completed vaccination schedule for COVID-19. Being a nursing student, being in the final years of the course and being a woman are the factors that most influence the positive attitude of the students. The results obtained are motivating, because these students will be the future health professionals most likely to integrate health promotion programs through vaccination.
T-ALL Cells as Tool Cells for CAR T Therapy
Authors: Ren Anqi , Zhao Yuan , Zhu Haichuan
Published: April 2023

T-cell acute lymphoblastic leukemia (T-ALL) is a hematologic malignancy derived from T cells. Numerous CAR T therapies have been successfully applied to treat hematologic malignancies in the clinic. Nevertheless, there remain several challenges to the extensive application of CAR T cell therapy in T cell malignancies, especially in T-ALL. The main reason for CAR T therapy limitations is that T-ALL cells and normal T cells share antigens, which improves the difficulty of sorting pure T cells, resulting in product contamination, and would lead to CAR T cell fratricide. Thus, we considered creating a CAR on T-ALL tumor cells (CAR T-ALL) to prevent fratricide and eliminate tumor cells. We found that T-ALL cells transduced with CAR would actually commit fratricide. However, CAR T-ALL could kill only tumor cells on T-ALL cell lines, and other types of tumor cells had no killing function after being transferred with CAR. Furthermore, we created CD99 CAR with expression controlled by the Tet-On system on Jurkat cells, which could avoid the fratricide of CAR T-ALL during proliferation, ensuring the controllability of the killing time and effect. Jurkat transduced with a CAR-targeting antigen, which was expressed on other cancer cells, could kill other cancer cell lines, demonstrating that T-ALL cells could be used as tool cells for cancer therapy. Our study supplied a new feasible treatment regimen for cancer treatment in the clinic.

Several effective COVID-19 vaccines are administered to combat the COVID-19 pandemic globally. In most African countries, there is a comparatively limited deployment of vaccination programs. In this work, we develop a mathematical compartmental model to assess the impact of vaccination programs on curtailing the burden of COVID-19 in eight African countries considering SARS-CoV-2 cumulative case data for each country for the third wave of the COVID-19 pandemic. The model stratifies the total population into two subgroups based on individual vaccination status. We use the detection and death rates ratios between vaccinated and unvaccinated individuals to quantify the vaccine’s effectiveness in reducing new COVID-19 infections and death, respectively. Additionally, we perform a numerical sensitivity analysis to assess the combined impact of vaccination and reduction in the SARS-CoV-2 transmission due to control measures on the control reproduction number (Rc). Our results reveal that on average, at least 60% of the population in each considered African country should be vaccinated to curtail the pandemic (lower the Rc below one). Moreover, lower values of Rc are possible even when there is a low (10%) or moderate (30%) reduction in the SARS-CoV-2 transmission rate due to NPIs. Combining vaccination programs with various levels of reduction in the transmission rate due to NPI aids in curtailing the pandemic. Additionally, this study shows that vaccination significantly reduces the severity of the disease and death rates despite low efficacy against COVID-19 infections. The African governments need to design vaccination strategies that increase vaccine uptake, such as an incentive-based approach.

Coverage of COVID-19 vaccines in Somalia remains low, including among health workers. This study aimed to identify factors associated with COVID-19 vaccine hesitancy among health workers. In this cross-sectional, questionnaire-based study, 1476 health workers in government and private health facilities in Somalia’s federal member states were interviewed face-to-face about their perceptions of and attitudes toward COVID-19 vaccines. Both vaccinated and unvaccinated health workers were included. Factors associated with vaccine hesitancy were evaluated in a multivariable logistic regression analysis. Participants were evenly distributed by sex, and their mean age was 34 (standard deviation 11.8) years. The overall prevalence of vaccine hesitancy was 38.2%. Of the 564 unvaccinated participants, 39.0% remained hesitant. The factors associated with vaccine hesitancy were: being a primary health care worker (adjusted odds ratio (aOR) = 2.37, 95% confidence interval (CI): 1.15–4.90) or a nurse (aOR = 2.12, 95% CI: 1.05–4.25); having a master’s degree (aOR = 5.32, 95% CI: 1.28–22.23); living in Hirshabelle State (aOR = 3.23, 95% CI: 1.68–6.20); not having had COVID-19 (aOR = 1.96, 95% CI: 1.15–3.32); and having received no training on COVID-19 (aOR = 1.54, 95% CI: 1.02–2.32). Despite the availability of COVID-19 vaccines in Somalia, a large proportion of unvaccinated health workers remain hesitant about being vaccinated, potentially influencing the public’s willingness to take the vaccine. This study provides vital information to inform future vaccination strategies to achieve optimal coverage.

Recent studies indicate an extremely high prevalence of long-term neurological manifestations among COVID-19 survivors, with nearly a third of patients diagnosed with neurological or psychiatric disorders in the first 6 months after acute COVID-19. Unlike the acute neurological manifestations of COVID-19, the pathophysiological mechanisms of long COVID-19 remain poorly understood. Several studies have concluded that both the CNS and the PNS are involved in patients with long COVID. The most common neurological symptoms were fatigue, memory/attention deficits, sleep disturbances, and myalgias, with each symptom occurring in one third of patients with prior SARS-CoV-2 infection. The impact of COVID-19 on patients, regardless of severity, extends beyond hospitalization for severe cases to continued deterioration in quality of life, mental health, and employment problems. Doctors' awareness of this condition, strict control of metabolic changes and risk factors for cardiovascular diseases, and effective and safe treatment of identified disorders are the main tasks in the management of patients with this pathology.

The prevalence of depressive disorders in modern society is quite high, which is an important medical and social issue throughout the world. The role of psychosocial factors in the development of cardiovascular diseases, as well as the high comorbidity of cardiac pathology and depression in recent decades, are beyond doubt. Therapy for depressive disorders in cardiac patients should combine efficacy and safety, as well as ensure patient adherence to therapy. Despite the rather large number and wide availability of antidepressants, including those that are relatively safe in relation to the treatment of depression in cardiovascular pathology, there is a need to search for new depressive disorders treatment options that are even safer and more effective, especially in patients with various comorbid pathologies and concomitant therapy.

Biographies révolutionnaires et migrations : les Français à Nice en 1794 d’après les cartes de sûreté
Authors: Doria Alessandra
Published: April 2023

Sur la base des données relatives aux 3 519 individus, hommes et femmes, recensés dans les registres des cartes de sûreté délivrées en décembre 1794 aux habitants de Nice, cet article analyse les phénomènes migratoires qui intéressent la ville dans la deuxième moitié du XVIIIe siècle et étudie les changements déterminés par l’annexion à la France révolutionnaire en septembre 1792. Du point de vue géographique et social, on observe que Nice, ville frontière, évolue au XVIIIe siècle au fil d’une migration de type infrarégional – Piémont, Gênes, Provence – d’hommes et de femmes appartenant en grande majorité au monde du commerce et de la manufacture. Avec l’annexion, on constate l’arrivée massive de Français et Françaises et le reflux des migrants provenant de l’Italie. L’étude ponctuelle des biographies de trois migrants ayant participé au processus révolutionnaire local permet d’interroger le rapport entre politique et migration. Ces exemples illustrent trois façons différentes dont, dans un contexte de participation démocratique, l’engagement révolutionnaire se noue aux parcours de migration.
Le gouvernement d’Alphonse de Poitiers en Auvergne
Authors: Roques Rémy
Published: April 2023

En 1250, de retour d’Égypte où il avait accompagné son frère Louis Ix, Alphonse se retrouva à la tête d’une vaste principauté. En 1241, il avait reçu en apanage le Poitou et l’Auvergne. Le Toulousain, le Rouergue, l’Albigeois, l’Agenais, le Quercy et le Venaissin lui revinrent suite au décès de son beau-père, le comte de Toulouse Raimond VII. En Auvergne, Alphonse recourut aux moyens qui, depuis le XIIe siècle, avaient garanti le succès du pouvoir royal : diffusion de l’hommage, concession de chartes de franchises et de traités de pariage, développement d’une administration composée d’hommes du Nord et d’aristocrates locaux. Toutefois, contraint de résider le plus souvent à Paris à cause de sa maladie, il fut amené à perfectionner ses méthodes de gouvernement. Messagers et tournées d’enquêteurs permirent de combler l’éloignement physique du prince et de faire le bilan de son administration locale. Le renforcement du dialogue avec la noblesse et les villes, la consolidation du réseau castral et une meilleure perception des revenus ont aussi contribué à transformer un domaine d’origine féodale en une principauté territoriale.

L’écriture de la bourgeoisie aux XIVe-XVe siècles. Un « livre de raison » de la famille Cruzat ?
Authors: Ramírez Vaquero Eloísa
Published: April 2023

Les Archives Générales de Navarre abritent, dans les fonds de la Chambre des Comptes, un «Livre de caisse» de la famille Cruzat. Il s’agit, nous le savons désormais, d’un livre de famille ou de raison, commencé en 1350 et contenant des informations jusqu’au milieu du XV e siècle. Ce livre permet de constater que les Cruzat, famille de commerçants du Burgo de San Saturnino de Pampelune, entretenaient des relations commerciales et familiales avec une grande partie de la bourgeoisie locale et disposaient d’un important réseau de relations commerciales de l’autre côté des Pyrénées. Leurs contacts, tissés notamment à travers un partenaire de la famille, un commerçant béarnais, s’étendaient dans l’ensemble du Midi et au reste de la France. Outre la gestion des affaires et l’articulation d’une série de sociétés commerciales, le livre présente d’intéressants aspects concernant la mémoire ainsi que l’administration du patrimoine familial. En attendant sa transcription complète, qui sera bientôt publiée, nous présentons ici une première étude de son contenu.

A century ago, the legal historien and «chartiste» Paul Guilhiermoz (1860-1923) armed with a deep knowledge of the sources of historical metrology, mapped out the evolution of agrarian measures in the Southwest of France during the Middle Ages and interpreting them through the use of calculus. Somewhat neglected afterwards, his demonstration is here strengthened by the analysis while at the same time some of his results have been submitted to close scrutiny.
Vie et destin d’une communauté religieuse au miroir de son livre de raison : la Visitation d’Albi (1783-1791)
Authors: Rives Danielle

Rives (Danielle), Vie et destin d’une communauté religieuse au miroir de son livre de raison : la Visitation d’Albi (1783-1791), Annales du Midi, vol. 129, no 297, janvier-mars 2017, p. 43-63

Le dernier livre de raison du monastère de la Visitation d’Albi, rédigé de 1783 à 1791, constitue un document passionnant sur la vie quotidienne d’une communauté religieuse confrontée aux mutations de la fin du XVIIIe siècle. Conservé aux archives départementales du Tarn, ce registre présente, au fil de longues et répétitives listes, les recettes et dépenses d’un couvent féminin. Derrière les comptes, apparaissent non seulement les gestes et les goûts des moniales, mais également les réseaux sociaux tissés avec la bourgeoisie albigeoise qui en font des actrices en leur siècle. L’observation attentive des sources de revenus, comme celle des charges communautaires, permet d’appréhender la spécificité d’un mode de vie plus ou moins conforme à la spiritualité souhaitée par Jeanne de Chantal et François de Sales, fondateurs de l’ordre.
PROBATION UPON HIRING: A NEED FOR TRANSFORMATION
Authors: DRACHUK M.A.
Published: April 2023

This publication invites discussion on the issue of probation upon hiring as an institution in need of transformation, in the author’s opinion. The goal of probation should be specified, since it can be established either to test the fitness of an employee for the job assigned, or for the employee to decide whether the offered job is suitable for them. Also, it is necessary to resolve the issue of the exact rationale and the moment in time the labor relations with an employee should be terminated during probation in case they do not succeed. The author suggests introducing a new special rationale - termination of a labor contract at the end of the employee’s probation without further employment of the worker at this employer’s based on a wrongdoing by the employee during probation or in case the employer discovers that the worker’s professional aptitude does meet the employer’s requirements. These amendments to the legislation can allow identifying fault-based (disciplinary) grounds for the labor contract termination among all the cases when the worker was considered to have failed the probation upon hiring, as well as to link them directly to the institution of labor discipline. It is no secret that in practice, multiple issues regarding the interaction between the regulatory provisions on probation outcomes and the regulatory provisions on disciplinary responsibility of workers arise: these problems should be resolved, since the court practice examples provided by the author often show diametrically opposed conclusions made by the courts based on their interpretation of statutory regulations. Also, the paper invites discussion on the renunciation of possible replacing probation by a fixed-term temporary labor contract and establishing a probation model for the change in employment functions (transfer to a new job).
COMPARATIVE LEGAL ANALYSIS OF THE INSTITUTE OF SELF-DEFENSE BY EMPLOYEES OF LABOR RIGHTS IN THE EAEU COUNTRIES
Authors: ZOLOTOV I.S.
Published: April 2023

The problem of protecting the labor rights of workers definitely attracts the attention of labor /scientists not only within the framework of national legal, but also cross-border legal field. Thus, new issues arise in this area during the unification of labor legislation within the framework of the Eurasian Economic Union. If the jurisdictional ways of protecting labor rights are to some extent developed within the framework of the national legal order of the member states of the Union, then the institution of self-defense is deprived of the attention of the legislator in these legal orders. In this regard, it seems important to analyze such a way of protecting rights as self-defense, guided not only by the ideas of the national development of the institute in the legislation of the Eurasian Economic Union member countries, but also its implementation within the framework of Union labor law. This work, as a scientific try to study the institute of self-defense by employees of their labor rights in the countries of the Eurasian Economic Union, takes as its basis a comparative legal scientific method. Applying this method, we can conclude that the legal model of self-defense of employees of their labor rights can be unified due to the uniform understanding of its nature by the legislation of most of the member countries of the Eurasian Economic Union. Nevertheless, the defective and obviously insufficient elaboration of the regulation of labor and legal self-defense in the studied legal systems shows a number of practical and theoretical problems that will ultimately affect the consolidation of such a legal model1 within the framework of the Eurasian Union labor law. In this regard, it seems important to present a single legal definition of self-defense, comprising the fundamental features of this method of protection. The adoption of such a term will allow to form a uniform understanding not only among labor scientists, but also among law enforcement agencies, and will serve as a starting point for the further development of the institute of self-defense in the Eurasian Economic Union.

Мета. У пацієнтів-підлітків з ідіопатичним сколіозом (АІС) рентгенографічні спостереження є золотим стандартом аналізу деформації хребта з негативними довгостроковими наслідками. Система Formetric 4D - більш безпечний варіант для оцінки пацієнтів з АІС у порівнянні зі стандартною рентгенографією. Методи. Чотирнадцять добровольців з АІС пройшли 30 замірів Formetric 4D. Шістдесят чотири пацієнта з АІС відправили до звичайних клінік. Оцінка включала стандартні рентгенограми і вимірювання топографії поверхні, порівняльний аналіз якої виконується. Результати. Після оцінки результатів сканування повторювалося у той же день. Стандартне відхилення  +/- 3,4 градуса для вимірювань сколіозного викривлення. Також визначався коефіцієнт надійності (Cronbach), який був дуже високим (0,996). Вимірювання Formetric 4D відрізняється від рентгенографічних вимірювань у середньому на 9,42 (поперековий відділ) і 6.98 (грудний відділ) градусів, у той час як кореляція між двома вимірами була велика (95%), а довірчий інтервал [ДІ]), склав 0,758 (поперековий відділ) і 0,872 (грудний відділ) відповідно.
