Automatic air pluvation system for physical modelling applications
Authors: Wu Jinbiao , Kouretzis George , Pineda Jubert , Suwal Laxmi , Gibson Ross , Goodwin Michael
Published: November 2021

This paper presents an air pluviation system, developed to facilitate 1g physical model tests in granular soils. The deposition process is fully automated and requires minimal input from the operator, thereby significantly reducing the time required to deposit large volumes of granular material, improving the uniformity of the prepared specimens and the reliability of test results. The components comprising the pluviation system have been calibrated to produce loose-to-very dense sand beds, of relative density that ranges between Dr = 7% and  > 100% of the maximum density achieved with the procedures described in the pertinent standards. The testing chamber where sand is deposited is instrumented with an array of pressure sensors, and the rig is equipped with a miniature cone penetration testing (mini-CPT) device. Measurements from the earth pressure sensors and cone tip resistance profiles are used to evaluate how friction at the sand–chamber interfaces affects the distribution of geostatic stresses inside the chamber, the uniformity of sand beds and boundary effects during deposition and during mini-CPT testing. The air pluviation system allows preparing layered sand profiles by adjusting the deposition parameters on the fly, and this feature is demonstrated through the analysis of mini-CPT tests performed in layered sand beds.

Published: November 2021

Compartilhamos os resultados de duas pesquisas interventivas realizadas em escolas brasileiras de ensino básico a partir da implementação de unidades didáticas como instrumentos orientadores dos processos de ensino e de aprendizagem. Esses instrumentos são compostos por atividades articuladas de práticas de linguagem e por diferentes gêneros textuais, além de serem informadas por abordagens pedagógicas de estudos sistêmicos-funcionais da linguagem e da educação científica, ambos desenvolvidos no campo indisciplinar da Linguística Aplicada. Com a comparação das respostas apresentadas pelos alunos participantes para um mesmo questionário, aplicado antes e após as intervenções pedagógicas, o resultado produtivo da implementação das unidades didáticas foi comprovado. Após as intervenções, os alunos complexificaram as próprias compreensões sobre ciências, o que foi revelado especialmente pela inclusão de pesquisas sobre fenômenos linguísticos nos contextos das práticas científicas descritos pelos alunos. Esse fato foi observado de forma mais expressiva nas respostas dos alunos da escola privada, os quais participaram da intervenção em que a própria língua materna foi objeto de investigação, diferentemente dos alunos da escola pública, que participaram da intervenção em que a Língua Portuguesa foi utilizada numa perspectiva instrumental. Nesse último caso, o português foi utilizado em função da investigação de objetos de pesquisa do interesse de outra disciplina escolar.

Published: November 2021

Türkiye’de 1950’li yıllardan 1980’li yıllara kadar emek gücüne dayalı kentleşme süreçleri meydanagelmiş ve bu süreç 1980’lerden itibaren kentsel mekânda gerçekleşen neoliberal uygulamalarabağlı olarak yerini sermaye birikimine bağlı kentleşme süreçlerine bırakmıştır. Kentsel mekânlardabu şekilde meydana gelen değişim ve dönüşümlerin en somut örneklerinden biri, kent merkezlerindeyer alan endüstriyel tesislerin değişen ekonomik şartlara bağlı olarak yerini alışveriş merkezlerinebırakmaları olmuştur. Bu çalışmanın motivasyonunu; “fabrikaya yönelik aidiyet duygularınasahip üreten bir toplumdan, alışveriş merkezinin misafirleri durumundaki tüketen bir topluma geçişsürecinde kentsel mekân nasıl şekillenmektedir?” sorusu oluşturmaktadır. Hizmete girdiği 1950’liyıllarda Hatay’ın en büyük üretim merkezi olan Ak-İş iplik fabrikası zamanla işlevini yitirerek yıkılmışve onun yerine bir alışveriş merkezi inşa edilmiştir. Emek gücünden sermaye birikimine doğrugerçekleşen bu dönüşümün Antakya kentsel mekanını nasıl şekillendiğini ampirik analizlerle ortayakoymak bu çalışmanın temel amacıdır. Çalışmada hem nicel hem de nitel verilerin birlikte değerlendirilmesianlayışını benimseyen karma yöntem kullanılmıştır. Nitel veriler, Ak-İş iplik fabrikasındanemekli olmuş 5 kişiyle gerçekleştirilen derinlemesine görüşmelerden elde edilmiştir. Nicel verilerinelde edilebilmesi için ise Antakya’da ikamet eden 265 katılımcıya anket uygulanmıştır. Çalışmanınnitel bulguları; emek gücü, kentsel bellek ve mekân kullanımı olmak üzere üç temaya dayanmaktadır.Nitel bulgular, bir üretim mekânı olarak fabrikanın yeni mekânların üretilmesinde önemli rollerüstlendiğini göstermiştir. Nicel verilerden ve alan araştırmalarından elde edilen bilgiler ise; kentselmekânın tüketim ve sermaye odaklı olarak önemli değişim ve dönüşümler geçirdiğini ortaya koymuştur.

Published: November 2021

Objetivo: Analisar a relação entre estrutura de capital e governança corporativa.

Método: A amostra reúne as empresas listadas na BM&FBOVESPA no período de 2010 a 2014. Os dados foram coletados no website do BNDES e na base Economática® e a análise quantitativa foi realizada por meio de teste de diferenças entre médias, análise de correlação e regressão linear múltipla.

Resultados: As empresas não participantes dos níveis diferenciados de governança corporativa apresentam maior endividamento médio. No ano de 2012, as empresas receberam maior volume de recursos financiados pelo BNDES, destacando-se a empresa Petrobras. Os resultados apontam que a governança corporativa influenciou negativamente o endividamento subsidiado, e que a rentabilidade apresentou uma relação negativa com todos os quatro tipos de endividamento analisados, confirmando-se no mercado brasileiro o que preceitua a Teoria Pecking Order.

Contribuições: A pesquisa contribui para enriquecer a bibliografia sobre estrutura de capital, ao incorporar a dívida subsidiada como uma das variáveis explicativas do modelo. Devido à sua grande importância para o meio empresarial, e ao fato de os resultados dos estudos acadêmicos serem, em linhas gerais, heterogêneos, as discussões sobre estrutura de capital contribuem de alguma forma para o avanço nesse campo de pesquisa.
The Presumption of a Creative Nature (Originality) of Copyright Objects
Authors: Mikhailov S. V.
Published: November 2021

The paper is devoted to the doctrinal meaning and practical significance of the presumption of the creative nature (originality) of copyright objects. This presumption is not directly enshrined in Russian law, but it follows from the systemic interpretation of the rules dedicated to notion of the author. A citizen who created a work by his creative work is recognized as the author. The laws of many countries contain the presumption of originality of works, but its interpretations are diametrically different. At the present time, in the conditions of an increasingly accelerating and complicating civil turnover accompanied by the information revolution, legal and technical substantive approaches to the category of originality (as a synonym for creativity) as a common and only prerequisite for the protection of works by copyright and the continental copyright system have gradually begun to converge. At the same time, domestic judicial practice still unreasonably ignores the doctrine of substantial similarity of works based on the presumption of originality. The author proposes an authentic classification of disputes concerning the originality of works, the basis of which is the number of objects involved in the dispute.

The author builds a coordinate system, the criterion of which is the degree of change of the original work: identical copying — non-identical copying — processing — free creation of another original work. At the same time, the author emphasizes that a copy, even significantly different from the original, does not cease to be a copy. In legal terms, identical and non-identical copying constitutes reproduction that requires the consent of the author or copyright holder of the original work. A necessary sign of processing is the purpose of the author of the changes to expand the possibilities of using the original work; processing also requires the consent of the author or copyright holder with respect to the original work. Non-identical copying and reworking should be distinguished from creating a new work using an unprotected content of the original authentic work.
Elements of Precarious Employment in the Work of Scientifc and Pedagogical Workers
Authors: Chernykh N. V.
Published: November 2021

The paper highlights the problem of the growth of the segment of precarious employment in the work of researchers and the faculty, who work mainly in scientific and educational institutions (scientific and pedagogical workers). Besides the elements of precarious employment characteristic of the category of workers under consideration, the author considers the fixed-term nature of labor relations and the low level of the conditionally constant part of wages in the general structure of wages of scientific and pedagogical workers, which can be attributed to the legal prerequisites for the deterioration (precarization) of their labour regulation. In addition to the acts of federal legislation regulating the labor of scientific and pedagogical workers, the author analyzes the provisions of the relevant acts of social partnership for the period from 2015 untill 2023. The author highlights the problem of increasing the types of work included by the employer in the employment of the “second half of the day” of scientific and pedagogical workers without paying additional wages. The lack of legal regulation of the distribution of types of work performed by a scientific and pedagogical worker within a 36-hour working week is also noted by the author among the legal preconditions that, with appropriate law enforcement, worsen the conditions of employment of such workers due to the significantly increasing proportion of time that workers spend on achieving performance indicators and efficiency determined by the employer. In the conclusion of the paper, the author justifies amendments to the legislation in terms of regulating a fixed-term employment contract, establishing the share of guaranteed wages in the overall structure of wages, regulating the types of work included in the working hours of scientific and pedagogical workers at the level of a by-law, which cumulatively will promote sustainability of employment conditions for employees and improve their legal status.
The V. Schoeneman Case: Einsatzkommando 8, the Wehrmacht and the Holocaust
Authors: Grakhotskiy A. P.
Published: November 2021

In 1964, the trial of Werner Schoenemann, the commander of one of the 6 punitive units of the Einsatzkommando 8, took place in Cologne. The criminal was charged with mass executions of Jews on the territory of Belarus in late June — September 1941. The paper shows how the former Nazi tried to avoid criminal responsibility and what legal assessment by the German justice his atrocities received. V. Schoeneman denied his guilt and sought to shift responsibility for what he had done to the Wehrmacht troops. The defendant argued that the actions of extermination of Jews were carried out on the initiative of the German armed forces and were in the nature of reprisals; they were designed to force the local population to abandon the conduct of guerrilla warfare. Based on the testimony of the accused, law enforcement officers detained three officers of the 354th Infantry Regiment involved in the liquidation of the Jewish community of the town of Krupki (September 18, 1941). During the investigation, it was established that the service members provided support to members of the Einsatzkommando 8 during the execution, but were not the initiators of this atrocity. For complicity in the grave murders of 2,170 Jews in the settlements of Slonim, Borisov, Smolevichi, Krupki and others, V. Schoeneman was sentenced to 6 years in prison. When assigning such a lenient punishment, representatives of the German Themis relied on the dominant approach to assessing the criminal activities of former Nazis in the 1960s. According to the jury, the defendant was only a submissive executor of orders, an impersonal, devoid of his own motives “cog” in the mechanism of the Nazi state. V. Schoeneman did not repent of what he had done. For the former punisher, Jewish victims were still just dry figures in the reports, thanks to which he sought to make a career. Schoeneman’s case proves that Wehrmacht service members took an active part in the Holocaust along with members of the Einsatzkommandos. The genocide, unprecedented in the history of humankind, became possible only because of the broad participation of German citizens representing various social strata and professional groups.
An exploratory examination of the impact of technology and gender in a business-to-business sales encounter
Authors:   , Christ Paul Francis , Anderson Rolph Ely
Published: November 2021

During a selling encounter, the use of certain objects by a salesperson could send nonverbal signals to the buyer. One object that has become increasingly visible in sales presentations is the portable computer. The use of such technological devices is presumed to offer benefits to salespeople as they attempt to build a business relationship. Yet, no academic studies to date have specifically examined how organizational buyers respond to salespeople who utilize advanced technologies. Whether salespeople, who use advanced technology during a sales presentation, are viewed differently than those, who use little or no technology, is the main focus of this study. A secondary concern is the role gender plays in the buyer-seller dyad. Previous research has primarily examined the topic in terms of the salesperson gender and not the gender of the buyer. This study attempts to shed light on whether the buyer's gender is a contributing factor in the buyer-seller relationship. Additionally, the effect of salesperson's gender is taken up in an effort to address shortcoming in prior research. The research methodology involves an experimental approach with three treatment levels: salesperson use of technology, salesperson's gender, and buyer's gender. The dependent measures relate to the impressions buyers develop of a salesperson in five areas: (1) the salesperson's credibility; (2) the benefits offered by the salesperson's product; (3) the image of salesperson's company; (4) the salesperson's effectiveness in terms of buyer's behavioral intentions; and (5) the salesperson's performance during the presentation. Subjects for the study are 283 graduate business students. Each was presented with a booklet containing one of four treatment conditions: (1) female salesperson/minimal technology, (2) female salesperson/advanced technology, (3) male salesperson/minimal technology, and (4) male salesperson/advanced technology. Results indicate that salesperson's use of advanced technology may have an influencing effect on buyer's perceptions. Also, buyers may perceive salespeople differently depending on the salesperson's gender. Finally, no difference was found between female and male buyer's responses on general measurements, however, there were differences observed in female and male buyer's responses to different levels of technology. Overall, the study's findings may offer valuable insight for both salespeople and sales managers.

Efficacy of probiotic Lactobacillus reuteri on chronic generalised periodontitis: A systematic review of randomized controlled clinical trials in humans
Authors: Ahuja Vipin , Ahuja Annapurna
Published: November 2021

It is well recognized fact that periodontal diseases are caused by multifactorial etiologies; in which microorganisms play an important role. An essential component of therapy is to eliminate or manage these pathogens. This has been traditionally accomplished through mechanical means by scaling and root planning and adjunctive anti-infective therapy, which includes local and systemic antimicrobials. But the unwarranted use of antimicrobial is associated with adverse effects and development of resistance. To overcome these problems newer technologies have been tested in the field of periodontics; one of these therapies is use of probiotic. This approach of therapy is of interest to periodontist due to the aforementioned shortcomings of conventional methods.

A manual and electronic search was made for human studies up to November 2020 that presented systemic and local use of probiotics in generalised chronic periodontitis. A systematic approach was followed by two independent reviewers and included eligibility criteria for study inclusion, quality assessment, and determination of outcome measures, data extraction, data synthesis, and drawing of conclusion.

Only 3 randomized controlled human trials qualified, and they concluded that use of probiotic Lactobacillus Reuteri proves beneficial in improving clinical and microbiological parameters in generalised chronic periodontitis.

Authors: Kumari Priyanka , Khatri Manish , Bansal Mansi , Puri Komal
Published: November 2021

TheLaser Assisted New Attachment Procedure (LANAP) protocol is a laser based periodontal regenerative procedure and was patterned, conceptually, after the Excisional New Attachment Procedure (ENAP) to separate the diseased epithelium from the underlying connective tissue and to selectively vaporize and disrupt inflamed and necrotic tissue from connective tissue.

: The present study was designed to compare and evaluate the clinical efficacy of LANAP versus ENAP in the treatment of chronic periodontitis.

: Twenty periodontal pocket sites of ≥5mm in systemically healthy patients were selected and randomly allocated to either (ENAP) Excisional New Attachment Procedure (Group I) or (LANAP) Laser Assisted New Attachment Procedure (Group II). Patients were evaluated for Plaque Index, Gingival Index, Gingival Bleeding Index, Probing Depth, Loss of attachment, recession and VAS scores. Patients were recalled for follow up at 1 week, 1 month and 3 months at which clinical parameters were recorded.

: The results of the present study revealed statistically insignificant difference in both groups however clinically significant reduction in probing depth was seen with ENAP as compared to LANAP but laser procedure had less VAS scores as compared to ENAP.

Although probing depth reduction was more for ENAP, patient discomfort with less bleeding was observed with LANAP.

Published: November 2021

Apical migration of the gingival fiber attachment and marginal gingiva leads to gingival recession and can be caused due to many factors such as faulty tooth brushing, masochistic habits, periodontal disease etc. This causes dentinal hypersensitivity, aesthetic problems, root caries, cervical abrasion, and difficulty in maintaining oral hygiene and often possess a challenging situation for the clinician to deliver best care to the patients. This case reports about the use of SCTG along with coronally advanced flap.

To report a case of RT2 recession, older term – Millers Class II recession which showed promising result when root coverage procedure was done using sub-epithelial connective tissue and coronally advancing the flap.

A 62-year-old male patient was referred to the Department of Periodontology, with a chief complaint of hypersensitivity and downward shifting of gum in upper front left teeth region which was progressive in nature with no obvious medical history.

After achieving profound anaesthesia over the concerned region the recipient site was prepared. After which the donor tissue was retrieved from the palatal area using trap door method and placed over the recipient site. No root biomodification agents were used. The graft was stabilised using interrupted suture and then criss-cross suturing was done, and non-eugenol periodontal dressing was given.

The follow up results showed good outcome with predictable root coverage achieved using Sub-epithelial Connective Tissue Graft (SCTG) and coronally advanced flap in the canine region which is often the most difficult one to achieve complete root coverage because of canine prominence.

SCTG can be used successfully along with coronally advanced flap and clinicians must opt for such treatment modalities for patients benefit.

Published: November 2021

Misalignment and unbalance are a common fault occurring in the rotor system. A new approach for detecting misalignment and unbalance problems combining the intrinsic time - scale decomposition (ITD), the root mean square (RMS) and perceptron multilayer network (MLP) is proposed in this paper. Vibration signals of normal condition, misalignment horizontal, misalignment vertical and unbalance with different level are collected under different speed. ITD, nonlinear analysis of signals, was applied to decompose the vibration signals into 8 proper rotation components. The RMS values of 8 components are calculated and using as features vector. Last, the perceptron multilayer network was used for fault identification and classification. The proposed approach accurately classified and detection of unbalance and misalignment; the average accuracy achieved is 97.99%.

Published: November 2021

Lipaza lizosomalna katalizuje reakcję hydrolizy estrów cholesterolu i triglicerydów, której produktem są wolne kwasy tłuszczowe i wolny cholesterol, będące kluczowymi mediatorami wewnątrzkomórkowej homeostazy lipidowej. Deficyt LAL jest chorobą monogenową, spowodowaną obecnością patogennych wariantów molekularnych w genie LIPA, o dziedziczeniu autosomalnym recesywnym. W deficycie LAL dochodzi do kumulacji estrów cholesterolu i trójglicerydów w lizosomach, co wtórnie powoduje zwiększoną syntezę endogennego cholesterolu, apolipoproteiny B oraz lipoprotein o niskiej gęstości (VLDL). Diagnostyka deficytu kwaśnej lipazy jest łatwa, dzięki dostępnej obecnie metodzie badania aktywności enzymu w suchej kropli krwi. Analiza molekularna jest niezbędna celem weryfikacji diagnozy klinicznej i biochemicznej oraz analizy korelacji genotyp-fenotyp. Sebelipaza alfa jest rekombinowaną ludzką lizosomalną lipazą przeznaczoną do stosowania w enzymatycznej terapii zastępczej u pacjentów z niedoborem LAL.

Published: November 2021

Neurony dopaminergiczne śródmózgowia i neurony dopaminoceptywne prążkowia mają kluczowe znaczenie dla regulacji procesu uczenia się ze wzmocnieniem i motywacji do poszukiwania nagród. Aktywność oraz plastyczność tych neuronów jest w znacznej mierze zależna od pobudzającej transmisji glutaminianergicznej. W szczególności istotną rolę odgrywają receptory N-metylo-D-asparaginowe (NMDA) oraz metabotropowe receptory dla glutaminianu z grupy I, zwłaszcza mGluR5. W niniejszym artykule omówiono znaczenie aktywacji tych receptorów dla regulacji aktywności fazowej neuronów dopaminergicznych i plastyczności neuronów dopaminoceptywnych prążkowia. Opierając się na badaniach przeprowadzonych na zwierzętach z komórkowo specyficzną inaktywacją receptorów glutaminianu w układzie dopaminowym, przedstawiono również konsekwencje zaburzenia przekazywania sygnału zależnego od tych receptorów dla procesu uczenia się ze wzmocnieniem i motywacji do poszukiwania nagród. Omówione w artykule mechanizmy mogą mieć istotne znaczenie dla zrozumienia neuronalnego podłoża objawów towarzyszących chorobom psychicznym takim jak depresja, schizofrenia czy uzależnienia.

Published: November 2021

Coffee is one of the agricultural products whose processing requires special attention, in order to maintain its qualities preserved, in the post-harvest, different grain patterns can be obtained due to the adoption of techniques and the use of equipment that enable the separation of fruits by maturation stage, thus enabling the formation of more  homogeneous coffee batches when compared to the coffee batch without this separation (fruit mixture). The chemical composition of the coffee bean depends on genetic and environmental factors and pre and post-harvest management conditions. The presentwork aimed to characterize the physical-chemical attributes of the different coffee patterns obtained during the post-harvest of the fruits. Thirteen patterns were obtained, being: mix of dried fruits in high wind, mix of dried fruits in low wind, more mature green, natural float, natural raisin, float, natural cane green, natural ripe, natural ripe fermenting in water, natural ripe dried fermented, peeled, ripe peeled and pulped, in three random repetitions. The evaluated attributes were: Brix, total titratable acidity, pH, and ash content. The Natural Mature (MN) treatment was the best processing evaluated, as it provided the highest Brix value and the lowest titratable acidity value. The mature peeled, pulped mature, and natural mature treatments showed better sensory values, so they are recommended for post-harvest management to obtain a good drink quality.
Economic growth and sustainability: An analysis of the Environmental Kuznets Curve on the Legal Amazon
Authors: Wakim Vasconcelos Reis , Roma Jaques Otto , Magalhães Elizete Aparecida de
Published: November 2021

The objective of this work was to analyze how deforestation of the Legal Amazon (AMZ-L) is affected by the economic growth of the states it covers, from 2000 to 2017. This study is based on the Environmental Kuznets Curve theory (EKC), proposed by Grossman and Krueger (1991). We used the panel data method considering the fixed effects to answer the research problem. The hypothesis of the EKC, in fact, happens in the initial stage, showing that, with the increase in income, deforestation rates drop, causing the curve to reverse, taking an inverted “U” shape. However, at high-income levels, deforestation increases again, thus the curve takes an “N” shape. Considering this scenario, we can conclude that the increase in income alone does not guarantee deforestation reduction. However, we must emphasize that deforestation rates are lower than in the initial stage at high-income levels, showing the government intervention is needed.

EXPERIMENTAL AND MATHEMATICAL JUSTIFICATION OF THE APPLICATION DIGITAL TECHNOLOGIES FOR RECORDING THE POSITION OF THE LOWER JAW DURING TOTAL PROSTHETICS USING DENTAL IMPLANTS
Authors: Melnikov Yuri , Zholudev Sergey , Zaikin Dmitry
Published: November 2021

Subject. When prosthetics of toothless jaws are performed, the physiological position of the lower jaw must be determined before the final structures are made. In some cases, the use of temporary prostheses for several weeks may be useful to check for a new occlusion in a centric relationship. When the correct ratio is achieved, it is difficult to transfer them from the preliminary prostheses to the final ones. This article presents a case and a technique used to communicate information about the position of the lower jaw using a digital workflow.

To determine the optimal position of the lower jaw, a computer tomogram of the temporomandibular joint was used to mathematically measure the correct position of the head of the lower jaw.

Purpose. To describe a technique designed to transfer the inter-occlusal relations of the upper and lower jaws, using digital technologies in the prosthetics of full adentia using dental implants.

Methodology. On the example of a clinical case of rehabilitation of a patient, total removal of failed teeth was performed, followed by prosthetics of complete adentia with the installation of six implants on the upper and lower jaws. After the completion of the integration period, a cone-beam computed tomography was performed with the capture of the temporomandibular joint, and a scan of plaster models with installed gum shapers was performed. The obtained data were compared in a specialized program for mathematical calculation of the optimal position of the lower jaw. This information was used to produce registration templates for the manufacture of fixed structures supported by implants in the resulting central jaw ratio.

Results. A digital protocol for determining the central ratio of the jaws allowed us to transfer the information obtained in a virtual model of the temporomandibular joint to a permanent restoration based on implants.

Conclusion. The approach described in this article predictably conveys information about the optimal position of the lower jaw during prosthetics and allows you to perform the final restoration on implants with optimal occlusal ratios, based on a mathematical calculation performed in specialized programs.

Subject. Dentine pathology is widely prevalent among children in many countries around the globe, which determines the relevance of consideration, organisation and performance of different forms of health education activities for this part of the population. Programmes for dental disease prevention are represented by different methods and means, the purpose of which is creation of correct skills and abilities aimed at preservation and maintenance of oral cavity health. For blind and hyposeeing children, there is absence of special technology for teaching dental culture and rational hygiene of the oral cavity. Aim – studying and analysis and literature related to forms and methods of health education activities for children with consideration for their somatic status. Methods.The study was carried out based on the search for and analysis of original articles devoted to issues of dental disease prevention among children and adolescents in the following databases: ELIBRARY, PubMed, Medline, Cyberleninka. A total of 45 sources have been analysed (25 by Russian and 20 foreign authors). Conclusions. Preventive dental care programmes for conventionally healthy children at the modern stage of development are sufficiently effective, diverse in their contents, point at the necessity of further introduction of individual preventive care activities. Few organisational forms of health education activities have been developed for children with health limitations. There is no special method for organisation of health education activities for blind and hyposeeing children. These circumstances point at the necessity of development and introduction of correction methods for primary prevention of oral cavity diseases for this category of subjects.

Occlusion is a harmonious interaction of the dental system in dynamics, ending with the contact of teeth in conditions of their normal or disturbed ratio. This is a complex action involving teeth, masticatory muscles, TMJ. Occlusive disorders are a reflection of the external manifestations of pathological processes of the dental system. There is no doubt that in the search for etiological factors of occlusion disorders, the problem will manifest itself in one of the parts of the chewing system. The aim of the study was to optimize the early diagnosis of occlusive disorders in young patients without violating the integrity of the dentition. Materials and methods. The study included 36 patients without a violation of the integrity of the dentition aged 18 to 25 years (15 men, 21 women), who did not complain of pain in the dental system. A comprehensive dental examination was carried out and an individual "questionnaire and patient's health card" was filled out. Computer analysis with the T-Scan III occlusiography system of the company Tekscan (USA) was used to register the nature of the closing of the dentition, the study of diagnostic models in the PROTAR evo 7 KAVO articulator, as well as the study of the registration of the difference in the biopotentials of the masticatory and temporal muscles proper in patients in the phase of relative physiological rest and with maximum jaw compression using a four-channel electromyograph Synapsis NMF Neurotech (Russia). The results showed that the prevalence of occlusive disorders in the study group is 83.3%. The abnormal position of the teeth in the dentition in combination with malocclusion anomalies, non-physiological relief of the occlusal surfaces of the teeth formed due to various factors which cause the appearance of premature contacts. This prevents the harmonious sliding movements of the lower jaw and is accompanied by articulatory changes in the entire chewing system.
