An Unusual Presentation of a Thyroid Malignancy: A Case Report
Authors: M Irfan , A Baharudin , A Ananda Dorai
Published: November 2020

Patient with thyroid mass rarely presents in emergency situation. It is because the nature of the mass is that it usually increases slowly in size. Thus, any surgical intervention can be planned electively. The most common condition that necessitates urgent intervention, is upper airway compromise due to sudden rapid increase in size of the swelling. This can be due to intralesional bleeding or superimposed infection on the enlarged gland. We report a case of urgent completion thyroidectomy performed to a patient with fungating recurrent papillary carcinoma who present with bleeding from the mass externally.
An Undiagnosed Non Functioning Retroperitoneum Paraganglioma, Complicating A Gynaecological Surgery; A Case Report
Authors: AW Noraziana , B Hakim , R Alik , A Mokhtar
Published: November 2020

Paragangliomas are uncommon tumors arising from the neuroendocrine elements (chief cells) of the paraganglia and symmetrically distributed along the aorta in close association with the sympathetic chain. Although functional tumors are easier to diagnose due to the clinical findings caused by excess secretion of catecholamines and an elevation of the urinary catecholamine levels, however the diagnosis of nonfunctioning paraganglioma of the retroperitoneum is difficult and only few cases have been made before exploratory laparotomy. Although our patient was initially planned and operated by our gynaecological team, the incidental findings had to involve the general surgeons. She is fortunate that the tumour did not show any features of malignancy nor metastasis, however a long time follow up is needed in case of any possible recurrence.
Anti-CCP Antibodies: an Emerging Marker for the Early Diagnosis of Rheumatoid Arthritis
Authors: K Sarah , A Nadeem
Published: November 2020

Rheumatoid arthritis (RA) is a systemic disease affecting mainly joints. Since rheumatoid arthritis is a common and a world wide problem therefore accurate diagnosis of this disease is essential. In the past rheumatoid factor was considered as the only marker for diagnosing this disease; however rheumatoid factor is present in many other disorders and even in up to 15% of healthy population. For the detection of rheumatoid arthritis, over the years many auto antibodies have been reported such as anti perinuclear factor (APF) and anti keratin antibodies (AKA) but they were not specific and due to the tedious procedure used for their laboratory diagnosis, they could not become popular for the diagnosis of this disease. Recently anti-CCP antibodies have been reported and they are becoming popular due to their high sensitivity and specificity. It is hoped that in a couple of years time anti-CCP antibodies could be included in the ACR criteria for diagnosing RA.

Old-Russian needle-cases with an arched openwork back
Authors:   Russian Museum of Ethnography, Kuznetsova Valentina
Published: November 2020

Needle-cases of the 12th–13th century with arched openwork backs and rattle-pendants are known in historiography as an attribute of the Finno-Ugrian culture. The most of their finds come from kurgan cemeteries of the Ladoga and Upper-Volga regions. They have been also encountered in layers of Novgorod and Izborsk, burial grounds of Madi (Estonia), Zamikutye (former Gdov Uyezd), Tikhman’ga (Arkhangelsk Oblast), and Kintusovo (on the Salym River, Khanty-Mansi Autonomous District). Some objects come from the collection of the Teploukhovs from the Perm Cis-Urals, from the Ydzhydyel cemetery in the Republic of Komi and from Vaygach Island. These objects were manufactured using a wax model and have an abundant decoration. They have a typical for Northwestern Russia form of tubular needle-case, but the origin of their decoration (twisted cord, slanting guilloche, volutes, etc.) is related with the Volga and Kama region. These artefacts cannot be considered as exclusively Finno-Ugrian ones. They belong to the culture of Old Rus’ but are executed in a syncretic style reflecting the contacts between the North-West and North-East of the forest zone.

Ryurik Gorodishche, Yaroslavovo Dvorishche and Novgorod the Great
Authors:   Institute for the History of Material Culture Russian Academy of Sciences, Musin Aleksandr
Published: November 2020

The paper presents a hypothesis of the origin of Novgorod. The decrease of Gorodishche in the 890–930s corresponded to the emergence of settlements at Torgovaya Side. Its revival in the 930–950s was synchronous to the ag- glomeration at Sofiyskaya Side. The appearance of the Princely Court near the Market and the bridge over the Volkhov in the 970s and the construction of the Detinets in the 11th century completed the formation of the town.

The article discusses the effect of cathode polarization on the protective properties of powder epoxy coatings, assesses their operational reliability, statistics of failures and describes the problems found during their operation. In the process of applying commercially available pipes with epoxy powder coating on the existing gas pipeline, a not previously manifested defect was observed - the formation of dome-shaped swellings. This led to some restrictions on the use of epoxy powder coatings. With the advent of a new generation of epoxy materials, as well as in connection with the revision of the regulatory documentation GOST R 51164-98, the issue of removing these restrictions on their use for insulating large diameter pipes (up to 1,420 mm). Without additional protection has become topical. As a result, it became necessary to estimate the probability of the appearance of defects of this type when using modern powder coatings. We carried out laboratory studies of the effect of cathode polarization on the properties of modern two-layer epoxy coatings after exposure to them of shock loads of a certain size. The results indicate that the impact of such a mechanical load may cause the appearance of microdefects of the coating, which are not determined by the existing methods of control. Due to the penetration of electrolyte under the coating and the occurrence of certain physicochemical and electrochemical processes that are enhanced by imposing the potential of cathodic protection and increasing the operating temperature, these microdamages can serve as active centers for the formation of a cupola-shaped swelling.
The inhibition of steel corrosion in model pore liquid of the concrete by derivatives of phenol
Authors: Gedvillo I.A. , Zhmakina А.S. , Andreev N.N.
Published: November 2020

In the course of corrosion tests, the protective properties of sodium nitrite and phenol derivatives in the electrolyte simulating a pore liquid of concrete contaminated with chlorides were compared. The experiments were carried out not only in hermetically sealed cells but also and in conditions of free access of air. It was found that in hermetically sealed cells phenol and resorcinol inhibit corrosion of steel, but significantly inferior to the protective ability of sodium nitrite. Hydroquinone protects steel more effectively than nitrite under conditions of limited oxygen access to metal. However, there is a significant deformation of plastic cells, which may be due to the absorption of oxygen, and the corresponding inhibition of the cathode process. With natural aeration of the model electrolyte hydroquinone in concentrations (1….2 g/l) inhibits the corrosion process in 2…8 times. In this case, the samples were covered with a gray film with a blue tint, but unlike nitrite, full protection of steel was not observed. Large concentrations of hydroquinone under these conditions significantly activate the corrosion of steel.
Investigations of the corrosion activity of the KAlCl4 melts by the methods of physicochemical analysis
Authors: Filatov E.S.
Published: November 2020

Corrosion behavior of metal alloys in a melt of potassium chloroaluminate (KAlCl4) was investigated. Metal aluminum was used as a protector for protection against continuous frontal corrosion. The equilibrium potentials of aluminum and the corrosion potential of the alloys were measured. The data were obtained to evaluate the corrosion ability of the system of molten salt of potassium chloroaluminate - gas (argon) by measuring the redox potential of the specified environment depending on the composition of the gas atmosphere above it, i.e. from impurities of water vapor, hydrochloric acid, oxygen and other, for example, carbonaceous gases. The calculations of the protection efficiency using the potential difference between the metal aluminum and the protected material were performed. The regularities of changes in the equilibrium potentials of aluminum from the temperature and concentration were established as the fundamental data for possible use at determining the composition ratio of potassium chlorides and aluminum in potassium chloroaluminate as input data for the development of a sensor of composition of chloroaluminate potassium.

The protective efficiency of the volatile IFHAN-114 corrosion inhibitor (VCI) was determined by impedance spectroscopy under atmospheric corrosion of St3 steel and copper in livestock buildings containing trace amounts of carbon dioxide, ammonia and hydrogen sulfide in the regulatory allowable concentrations. A 0.1 M NaCl solution was used as the background electrolyte. The effect of the combined presence of NH3 and CO2 corrosion stimulants of metals in the air was modeled by introducing (NH4)2CO3 in concentrations of 10 and 100 mg/L into the background solution. To simulate the combined presence of NH3 and H2S in air, equivalent amounts of Na2S and NH4Cl were introduced into the background electrolyte solution to obtain (NH4)2S (10 and 100 mg/L) at specified concentrations. This resulted in the hydrolysis of NH4+ and S2- ions to form NH4OH and H2S, which are stable in the surface phase film. According to impedance spectroscopy, (NH4)2CO3 at a concentration of 10 mg/L acts as an corrosion inhibitor of steel in a 0.1 M NaCl solution, and IFKHAN-114 (nonequivalent mixture of polyaniline with benzoic acid), introduced into the solution along with this amount of ammonium carbonate, plays the role of a corrosion stimulator. However, with an increase in the concentration of ammonium carbonate, its inhibitory effect is decreased, and for IFKHAN-114, introduced along with the salt, on the contrary, is appeared. A similar pattern is observed for the copper electrode. In the presence of (NH4)2S, almost the same effect of salt and VCI is observed for steel and copper, but with some variation. A comparison of the data obtained by gravimetric tests and impedance measurements showed that in the latter case only qualitative results can be obtained, although they undoubtedly confirm the presence of the inhibitory ability of IFKHAN-114 in a chloride neutral solution.
Corrosion of the inner surface of the tanks with sulfurous oil and pyrophoric properties of formed deposits
Authors: Begishev, Ildar R. , Reformatskaya Irina I. , Podobayev Alexander N. , Ascheulova Irina I.
Published: November 2020

The corrosion rate of the inner surface of the tanks in contact with the natural vapor-gas phase of the tanks can reach 3 mm/year. On the surface of the metal simultaneously occur two corrosion reactions, namely, the first with the formation of iron oxides and hydroxides, the second - with the formation of sulfide compounds. The resulting corrosive deposits are pyrophoric ones and cause spontaneous combustion of the tanks. Replacement of the natural vapor-gas phase with a mixture of N2 + O2 (nitrogen protection) with an O2 content of not more than 7 vol.% leads to a decrease in the corrosion rate by more than 2 orders of magnitude and is up to 0.013…0.015 mm/year. Continuous operation of nitrogen system provides fire and explosion safety operation of the tanks as a result of the termination of the formation of pyrite. In tanks, steel corrodes by an electrochemical mechanism, since the thickness of the moisture film on their walls (105…106 monolayers) is commensurate with the thickness of the diffusion layer at the steel – electrolyte solution interface.
Curing of inorganic composition coating of aluminum – phosphate system
Authors: Demin S.A. , Petrova A.P.
Published: November 2020

Known methods for applying an inorganic composite coating are accompanied by its heat treatment at a temperature of at least 300 °C, which requires the use of furnaces. Recent developments have allowed to reduce the temperature of heat treatment to 90 °C for at least 3 hours or to 105 °C for at least 1 h, which allows the use of portable heating equipment. However, the use of any equipment with such prolonged heat treatment is not acceptable when applying corrosion protection to large structures, especially when their dismantling is impossible. The results of studies on the chemical curing of an inorganic composite coating that does not require heat treatment are presented. It is proposed to spray a hardener solution onto a composite coating having a more alkaline pH instead of heat treatment. When a hardener reacts with acidic residues of an inorganic binder on the surface of a dried coating, monosubstituted phosphates undergo a transition to poorly soluble two-and practically insoluble tri-substituted phosphates not only on the coating surface, but also on the inner surface of the pores, which leads to almost complete insolubility of the coating. Treatment of the coating with an aqueous solution of monosubstituted potassium phosphate, two-substituted potassium phosphate or potassium pyrophosphate gives the coating water resistance. The inorganic composite coating acquires a high protective ability (more than 1300 hours in a salt fog chamber) on steel parts after treatment with only aqueous solutions of mono-substituted or two-substituted potassium phosphate.
Research universal combined inhibitor for the oil and gas industry
Authors: Adigezalova M.B.
Published: November 2020

Using the gravimetric method, the inhibitory efficiency of the combined inhibitor with respect to hydrogen sulfide and carbon dioxide corrosion of St3 steel in model produced water MI was studied. Corrosion tests were carried out in 0,5 liter sealed vessels on St3 samples of size 30х20х1. Gossypol resin + MARZA was used as a multifunctional combined inhibitor. Diesel fuel and kerosene were used as solvent. It has been established that the protective effect of using a multi-functional combined inhibitor in formation water with oil containing hydrogen sulfide and carbon dioxide using kerosene as a solvent ranges from 75 to 96 and for diesel as 80 to 100. The combined inhibitor allows to achieve in the MI medium containing hydrogen sulfide and carbon dioxide in the process of daily testing the corrosion rate of steel is about 0,04 g/m2·h. only in a concentration of not less than 70 mg/l. However, with an increase in the duration of the test by an order of magnitude, a similar corrosion rate is observed already at an inhibitor concentration of 50 mg/l. The same is characteristic of carbon dioxide and hydrogen sulfide - carbon dioxide solutions.
Quantitative Assessment of Bone Marrow Edema in Adolescent Athletes with Lumbar Spondylolysis Using Contrast Ratio on Magnetic Resonance Imaging
Authors: Nakamae Toshio , Kamei Naosuke , Tamura Takayuki , Kanda Tsukasa , Nakanishi Kazuyoshi , Adachi Nobuo
Published: November 2020

Study Design: Prospective cohort study.Purpose: To quantitatively evaluate bone marrow edema (BME) in the pedicle on magnetic resonance imaging (MRI) for adolescent athlete patients with spondylolysis.Overview of Literature: Spondylolysis, a stress fracture of the pars interarticularis, is a common occurrence in adolescent athletes with low back pain. T2-weighed fat-saturated MRI is reportedly useful for the detection of BME in the pedicle in the early stage of spondylolysis; however, to our knowledge, the quantitative assessment of BME in spondylolysis has not been reported.Methods: Adolescent athletes with spondylolysis, including those with symptoms of low back pain, were enrolled. The sporting activity of the patients was restricted, and a hard brace was attached to the spine. The BME range of interest was taken on T2-weighed fat-saturated MRI, and the signal intensity (SI) of the BME (SIedema) was measured. The contrast ratio (CR) between the SI of the BME and SI of the spinal cord (SIcord) was calculated per the following formulae: CRedema=(SIedema–SIcord)/(SIedema+SIcord). The CR of the normal pedicle was measured as a control per the following formulae: CRcontrol=(SIcontrol–SIcord)/(SIcontrol+SIcord).Results: The study enrolled 32 men and one woman; the mean patient age was 15.2 years (range, 12–18 years). The average CR of the edema and normal pedicle at the first visit was 0.506 (range, 0.097–0.804) and 0.137 (range, -0.741 to 0.572), respectively. The CR of the edema was significantly higher as compared to that of the normal pedicle (p<0.01). MRI that was performed 1 month after the first visit showed that the CR of the edema had decreased to 0.204 (range, -0.152 to 0.517). The CR of the edema 1 month thereafter was significantly lower than that at the first visit (p<0.01).Conclusions: Quantitative assessment of BME using CR on MRI is useful in the evaluation of the healing process of spondylolysis.

Study Design: This is a retrospective observational study with an outpatient setting.Purpose: This study aimed to describe the effects of duloxetine (DLX) administration for postsurgical chronic neuropathic disorders (both pain and numbness) following spinal surgery in patients without depression.Overview of Literature: Although several reports indicated the potential of DLX to effectively treat postoperative symptoms as a perioperative intervention, there have been no reports of its positive effect on postsurgical chronic neuropathic disorders.Methods: A total of 24 patients with postsurgical chronic pain and/or numbness Numeric Rating Scale (NRS) scores of ≥4 were enrolled. All patients underwent spine or spinal cord surgery at Keio University Hospital and received daily administration of DLX for more than 3 months. The mean postoperative period before the first administration of DLX was 35.5±57.0 months. DLX was administered for more than 3 months at a dose of 20, 40, or 60 mg/day, and the degree of pain and numbness was evaluated using the NRS before administration and 3 months after administration. Effectiveness was defined as more than a 2-point decrease in the NRS score following administration.Results: In terms of the type of symptoms, 15 patients experienced only numbness, eight experienced both pain and numbness, and one experienced only pain. Of the 24 patients, 19 achieved effective relief with DLX. DLX was effective for all patients with postsurgical chronic pain (n=9), and it reduced postsurgical chronic numbness in 18 of 23 patients. No significant difference was observed in background spinal disorders. DLX was not effective for five patients who complained only of postsurgical chronic numbness.Conclusions: This study reports the effectiveness of DLX for postsurgical chronic neuropathic disorders. Although DLX reduced postsurgical chronic pain (efficacy rate=100%) and numbness (78.3%) in certain patients, further investigation is needed to determine its optimal use.
Quantitative Evaluation of the Diffusion Tensor Imaging Matrix Parameters and the Subsequent Correlation with the Clinical Assessment of Disease Severity in Cervical Spondylotic Myelopathy
Authors: Nischal Neha , Tripathi Shalini , Singh Jatinder Pal
Published: November 2020

Study Design: We performed a prospective observational study of 52 patients who were clinically suspected of cervical spondylotic myelopathy (CSM), based on the modified Japanese Orthopaedic Association (mJOA) score, and were referred for magnetic resonance imaging (MRI) of the cervical spine.Purpose: To evaluate the quantitative parameters of the diffusion tensor imaging (DTI) matrix (fractional anisotropy [FA] and apparent diffusion coefficient [ADC] values) and determine the subsequent correlation with the clinical assessment of disease severity in CSM.Overview of Literature: Conventional MRI is the modality of choice for the identification of cervical spondylotic changes and is known to have a low sensitivity for myelopathy changes. DTI is sensitive to disease processes that alter the water movement in the cervical spinal cord at a microscopic level beyond the conventional MRI.Methods: DTI images were processed to produce FA and ADC values of the acquired axial slices with the regions of interest placed within the stenotic and non-stenotic segments. The final quantitative radiological derivations were matched with the clinical scoring system.Results: Total 52 people (24 men and 28 women), mean age 53.16 years with different symptoms of myelopathy, graded as mild (n=11), moderate (n=25), and severe (n=16) as per the mJOA scoring system, underwent MRI of the cervical spine with DTI. In the most stenotic segments, the mean FA value was significantly lower (0.5009±0.087 vs. 0.655.7±0.104, p<0.001), and the mean ADC value was significantly higher (1.196.5±0.311 vs. 0.9370±0.284, p<0.001) than that in the non-stenotic segments. The overall sensitivity in identifying DTI metrics abnormalities was more with FA (87.5%) and ADC (75.0%) than with T2 weighted images (25%).Conclusions: In addition to the routine MRI sequences, DTI metrics (FA value better than ADC) can detect myelopathy even in patients with a mild grade mJOA score before irreversible changes become apparent on routine T2 weighted imaging and thus enhance the clinical success of decompression surgery.

Published: November 2020

Study Design: This was a retrospective clinical study.Purpose: This study aimed to evaluate the effect of combination therapy with zoledronic acid and teriparatide on the risk of new vertebral fracture (NVF) in type 2 diabetes mellitus (T2DM) patients after percutaneous kyphoplasty (PKP).Overview of Literature: Although T2DM had been associated with bone fragility and increased fracture risk, it remains unknown whether patients with T2DM could expect similar benefit from the combination therapy with zoledronic acid and teriparatide following PKP.Methods: Total 106 diabetic patients who had undergone PKP and had received anti-osteoporosis treatment for osteoporotic vertebral compression fracture were enrolled and allocated into the following two groups: group I (n=52, zoledronic acid) and group II (n=54, zoledronic acid plus teriparatide). The operating time, bone cement volume, and complications related to anti-osteoporosis treatment or PKP, if any, were recorded. The Visual Analog Scale (VAS) score and Oswestry Disability Index (ODI) were assessed at admission, at discharge, and at the final follow-up. Dual-energy X-ray absorptiometry scan of the hip for the measurement of the bone mineral density (BMD) was performed preoperatively and at the final follow-up for all the patients.Results: There was no significant difference in the age, body mass index, bone cement volume, or follow-up time of the groups. The mean follow-up duration was 22.5±1.6 months. All the patients had improved VAS and ODI, and group II had significantly better clinical outcomes than group I. All the patients had increased BMD at the latest follow-up, while group II exhibited significantly more improvement. The prevalence of NVF was lower in group II (11.5% vs. 7.4%, p=0.523). Male patients had a higher prevalence of NVF although the difference was not statistically significant.Conclusions: Combination therapy with zoledronic acid and teriparatide could improve the clinical outcomes, and BMD and had the potential to reduce NVF in diabetic patients following PKP.

The physiopathogenesis of adolescent idiopathic scoliosis remains unknown. However, a multifactorial pathogenesis is being assumed. Besides biomechanical, biochemical, and genetic factors, some studies have focused on congenital or acquired abnormalities in the vestibular organ with consecutive development of scoliosis. This study aims to analyze a possible correlation between any vestibular organ congenital or acquired pathologies and scoliosis based on the current literature. Therefore, we conducted a literature search in three databases, with search terms such as “scoliosis,” “organ of balance,” “idiopathic scoliosis,” “vestibular organ,” “spine,” and “balance.” Fifteen studies were selected and used for research. The relationship between scoliosis and vestibular organ abnormalities was recorded from all included works. Seven studies demonstrated a direct correlation between vestibular organ anatomical abnormalities and the form of the scoliotic spine. Another study confirmed the influence of the pathology of the vestibular organ on scoliosis but questioned whether it had an impact on the formation or the progression of the curvature. Others demonstrated a temporal overlap of the embryonic development of the vestibular organ and the beginning of pre-scoliotic characteristics, but their relationship remained questionable. In three studies, the correlation remained unclear, and any context has been denied. It seems unlikely that an isolated vestibular disorder can trigger structural scoliosis. However, the vestibular system pathologies may certainly occur in the multifactorial genesis of idiopathic scoliosis. Whether the correlation refers to the expression or the progression of scoliosis or may even have an influence on both remains unclear. New treatment options could be derived from these findings with a positive influence on the course of the deformity.

The article presents a constructive model of training bachelors in cybersecurity in an educational-digital environment. The concepts of "model" and "modeling" are analyzed. The meaning of the definition of "construct" as a whole, distinguished from other entities of a certain area, which is inaccessible to direct observation, but hypothetically deduced and / or constructed logically on the basis of observed features, with a sufficient degree of experimentally and logically validated, is verified. the concept used to represent it. The scientific position in relation to the conceptual field of the model of preparation of bachelors in cybersecurity in the conditions of educa-?ional-digital environment is determined. Based on theoretical analysis, the constructive model is able to reflect the spatial pedagogical relationships between the elements of the object under study. It is determined that the conceptual model of training bachelors in cybersecurity in an educational-digital environment consists of five constructs. Each of the five model constructs is characterized, namely target, conceptual, content, activity-technological and result-corrective. The purpose of the model is defined to form the readiness of bachelors in cybersecurity in the educational-digital environment for professional activity. It has been found out that the result of constructive model of preparation of bachelors in cybersecurity in the conditions of digital educational environment is the formed readiness of bachelors in cybersecurity for professional activity.

In the context of European chall-?nges, modern professional development of future teachers, requires specific approaches to designing the trajectory of self-determination and self-identification within the profession. The need of reforming the educational and qualification disciplines (courses) of higher school, which should be focused on the operation of knowledge and their critical thinking has been proved; the learning dynamics, the development of personal abilities and talents of students, the ability to take responsibility and be ready to teamwork have been substantiated. The overview of external and internal sources of professional development of future teachers in the context of reforming the training of future teachers has been presented.Purpose. Analysis of external and internal factors of professional development of future teachers based on the introduction of a competency-based approach for higher education. Results. The level of professional development of future teacher is a combination of theoretical knowledge, practical skills, methodical creativity and personal qualities of a specialist, which largely ensures the appropriate level of effectiveness of his pedagogical activities. The fulfillment of the tasks set before education will be provided under the condition of reforming the construction of approaches to the training of future teachers, expansion, enrichment and continuity of profe-?sional development. Methods. Analysis, synthesis, abstraction con-cretization, systematization, modeling, generation. Originality. The authors have analyzed internal and external factors of professional development of future teachers, the influence of the level of self-awareness of the specialist (I-concept) on the prospects of quality professional self-improvement or the creation of psychological barriers to success in the profession.

ntroduction. The article deals with the es-sential characteristics of multicultural education, which should be applied to the modern methods of foreign stu-dent adaptive preparation, who interacts with the repre-sentatives of the new cultural environment. Purpose. To explore the features of multicultural edu-cation aimed at foreign student’s preparing for practical activities of academic and social nature. Results. It is revealed that multicultural education is manifests in the peculiarities of persons, connections who are the representatives of different linguistic, ethnic or national groups. The concept of global thinking, that char-acterized by the ability of a foreign student to practically apply the existing socio-cultural skills and interpersonal activity, is considered. On the analysis of the researchers findings, the own interpretation of the concepts of «multi-cultural education» and «technology of multicultural educa-tion» is given.Conclusion. On the base of theoretical study, we con-cluded that multicultural education provides the need of adaptation process in the ways that will ensure the full activity of the individual in the academic and social envi-ronments: the preparation of linguistic, cultural and psy-chological character. In addition, the adaptation involves the development of global thinking principles, through which a foreign student is able to use the formed interper-sonal and sociocultural skills in a specific situations of interaction with representatives of another society. In this connection, it is possible to distinguish the main manifes-tations of multicultural education, which should be used in the process of acculturation preparation, such as: the use, with the practical information giving on the character-istics of other cultures, of practical elements, among which the audiovisual means may be used; the students' cultur-al knowledge developing in the way to ensure a uniform interpretation of the actions of other cultures representa-tives and will allow to prepare the foreign students for activities in the host country's cultural space; the practical consolidation of the acquired knowledge both through the cross-adaptation (with the interaction of different cultural groups during the preparation phase), and at the time of the formation of adaptation tasks that will provide a con-nection between the academic and social contacts of the individual.
