„Hey, seit wann denkst du so?“ Heterogenität als alltägliche Erfahrung für Schülerinnen und Schüler an beruflichen Schulen. Ergebnisse einer Frankfurter Studie
Authors: Sorg Petra
Published: October 2020

In Beruflichen Schulen findet der Religionsunterricht oft im Klassenverband statt. Sie eignen sich deshalb als hervorragendes Forschungsfeld, um Positionierungsprozesse in heterogenen „globalisierten“ Klassenräumen zu erforschen und Faktoren und Voraussetzungen interreligiösen Lernens zu bestimmen. Am Beispiel eines Konfliktfalles werden die Ergebnisse einer Mixed-Methods Studie präsentiert, in der 301 Lernende quantitativ mit geschlossenem Fragebogen befragt und sieben Interviews qualitativ ausgewertet wurden.

Lead-gold eutectic (LGE) has been recently proposed as an alternative target material for high power spallation sources. In order to compare the corrosive properties of LGE to the better-studied eutectic of lead-bismuth (LBE), an isothermal twin-loop made of SS 316L was built and operated at the Institute of Physics of the University of Latvia. We have measured the concentration of steel alloying elements dissolved in both alloys at the end of two test campaigns via ICP-OES. In case of LGE, a pronounced concentration increase of Fe, Ni, Mn and Cr is found in the liquid metal, which is significantly higher compared to LBE. Similar results were obtained during complementary investigations on material samples exposed to both alloys in this twin-loop at 400 ◦C and 450 ◦C. These findings indicate that in contact with LGE, SS 316L steel suffers from substantial chemical attack. Detailed investigations using structure materials other than SS 316L have to be undertaken before qualifying LGE as a serious alternative to LBE.

Published: October 2020

Financial distress is a condition where the company is experiencing financial difficulties prior to bankruptcy. This study aims to identify and explain the influence of the fundamental variables and macroeconomic variables in predicting the probability of financial distress. Based on the eight variables used, current ratio, debt to assets ratio, return on equity and total asset turnover ratio is a fundamental variable. While the sensitivity of inflation, exchange rate sensitivity and interest rate sensitivity included in macroeconomic variables. The population in this study are all porperti and real estate company listed on the Stock Exchange in 2014-2018. The sample selection using purposive sampling technique, acquired 23 companies in the sample with the five companies in the category of financial distress and 18 companies in the category of non financial distress. The analytical method used is logistic regression and sensitivity analysis. The results showed that the variable current ratio, debt to assets ratio, total asset turnover ratio, inflation sesnitivity, exchange rate sensitivity and interest rate sensitivity did not significantly affect the probability of financial distress. While return on equity significantly negative influence on the company’s financial distress.

Authors: Osorio Ayala Lesly D. , Cantos Tello Paola M. , Carvajal Endara Andrea S.
Published: October 2020

Gingival hyperpigmentation is produced by excessive melanin deposit, generating a dark gum coloring. Although it does not constitute a health issue, in some cases it usually represents an aesthetic problem that can affect psychologically, for which there are currently several treatment alternatives such as: surgery with scalpel, laser therapy, abrasion, cryosurgery, electrosurgery, among others. The aim of this literature review was to analyze the available information about gingival melanosis and the therapeutics that can be applied to improve the appearance of patients with this condition. Articles in English and Spanish, published during the period 2000-2020 in the PubMed, Medline, Scielo, Cochrane and Lilacs databases, were reviewed. It was concluded that the selection of the technique will depend on each particular case, however, the laser is the most relevant.
Details of the Horse Bridle from the Burial of the Sarmatian Horseman from Kovalevka Kurgan Cemetery
Authors: Klepikov Valeriy , Krivosheev Mikhail
Published: October 2020

Introduction. The article publishes and analyzes the materials founded by the kurgan research near the village of Kovalevka in the southern part of the Volga-Don interfluve. Kurgan No. 13 is part of a kurgan cemetery, where the burials look relatively simultaneous and can be interpreted as a cemetery of nomadic migrants, settled in this territory in the confrontation with other Sarmatian groups.

Methods. The authors pay special attention to the details of the horse bridle, to the type of the bits and cheek-pieces, and to the plaques, which decorated the straps of the headband. The traditional method of analogies is used for the analysis and interpretation of the material.

Analysis. The type of rod cheek-pieces with two rectangular loops for fixing the rein in the central part and disc-shaped tips at the ends became widespread in the Sarmatian environment at the turn of the era. The cheekpieces and plaques were decorated with gold foil applications. Such burials are known in the Lower and Middle Volga region, Lower, Middle and Upper Don region, Kuban and in the Crimea. The authors find the origins of the tradition of making and using bits and cheek-pieces of this type in the East, in the regions of Transbaikal, Tuva, Altai and Northern China. The analysis of the bridle allows making the conclusion that it belonged to professional warriors-riders of upscale status.

Results. The appearance of such burials coincides with the process of changing Sarmatian cultures at the turn of the eras, and probably the horsemen were active participants in these historical changes. However, it is impossible to define them as an ethnic group, or even to combine them within one archaeological culture. Therefore, the authors propose to see such riders as representatives of an intertribal aristocratic military group.
Sarmatian Graves with Hiding-Holes in the Bottom of Pits in Kurgan Cemeteries of the Lower Volga Region
Authors: Raev Boris
Published: October 2020

Introduction. The article discusses one of the types of hiding-holes that were made in Sarmatian graves of the Lower Volga region. Hiding-holes as a substantial element of a graves structure are typical for Sarmatian burials of the last century BC and the first centuries AD. They were built in the burial pit, as well as near it, as a rule, in the west soil. In the burial pit, these were usually made as niches in the bottom parts of the walls, though hiding-holes in the bottom of the graves are characteristic only for the Lower Volga region.

Methods and materials. There are not very many graves with hiding-holes in the Volga Region – eight in total, and none of them have been found in the neighboring regions, or only single cases are known. Archive data on excavations of the kurgans in the region allows the author to specify some essential construction details of the graves with hidingholes. These holes were dug out in the bottom of the grave pits; they are round in shape, 0.3–0.5 m in diameter and 0.3–0.6 m in depth. A deceased was placed over the holes. A principal item always placed in all hiding-holes is a bronze cauldron, which in some cases is accompanied by other types of metal and ceramic vessels. The author comprehensively applies several scholarly methods of archaeological research. The first stage of collecting and initial processing of material included methods of external and internal analysis of sources taking into account professional characteristics of researchers. The primary classification method based on the similarity of objects, as well as the traditional method of comparative typology, was used at the interpretation stage. The interpretation of materials also required the use of the classical method of extensive parallels including ethnological examples.

Results. Among the burials with hiding-holes in the bottom of the pits, the majority were burials of women. Considering not only the ordinary but also the sacred meaning that was attached to the cauldrons by the nomads of Eurasia, the author concludes that the hiding-holes in the bottom of Sarmatian graves blocked out by the body of the deceased, served not only as a secret place for treasures but had some others cult significance.
On the Study of Scythian Mobility Based on Paleoanthropological Materials
Authors: Dobrovolskaya Maria , Volodin Semen
Published: October 2020

Introduction. The paper is about the study of the human skeletal remains isotopic composition from Middle Don burial mounds of the Scythian time to characterize the population mobility. Methods and materials. The materials from the monuments of Kolbino 1, Ternovoe 1, Gorki I, Devitsa V, Durovka are considered. Data on the isotopic composition of strontium enamel in teeth and bone tissue is used to estimate the mobility of the population. Information on the isotopic composition of bone carbon collagen and nitrogen is also used to reconstruct food models that reflect cultural traditions as well as environmental patterns. Analysis. Values of 87/86 Sr of bone and tooth enamel are considered as markers of an individuals stay at different ages in a territory similar or different by geochemical parameters to regional Middle Don. Data on the isotopic composition of nitrogen and carbon in bone tissue from the burial mounds are considered with broad comparative data of the steppe Eurasian population of the Early Iron Age. Results. The authors discuss carbon delta values marking the use of C4 type photosynthesis plants. Millet is this cultural plant in Eurasian history of the Early Iron Age. This plant is widely spread in all steppe and nomadic cultures. The individual variability of carbon delta of Middle Don population is increased compared to all others. There are individuals who differ from the majority in lower carbon deltas corresponding to the C3 type of photosynthesis. This feature is proposed to consider as an evidence of contacts with the territories with the antique agriculture traditions.
Reflection of Solar Symbolism in the Burial Rite of the Kemi Oba Culture: Case Study of the Grave Cist Painting from Koyash Village
Authors: Kozhukhovskaia Iuliia
Published: October 2020

Introduction. The article focuses on the analysis of solar elements in the burial rite of the Kemi Oba culture of the Early Bronze Age.

Methods and materials. The material draws attention to the painting of the grave cist from Koyash (Vodnoye) village that presents a set of mythopoetic schemes and plots, their interpretation proceeds from the processes of comprehension of the outside world.

Analysis. The paper identifies the ideograms on the basis of the painting of the grave cist under study: the circle with a dot in its center, the concentric circle, the triangle. The burial rite of the Kemi Oba culture focuses on the conceptualization of the afterlife in terms of observations of the solar nature, which is consistent with the prevailing Indo-European concepts of the Bronze Age. The sign of the concentric circle in the Kemi Oba culture appears as a solar symbol based on the analogies in the Indo-European mythology. The ideogram is part of the plot with dynamic character, and participates in the mythopoetic scheme based on the dichotomies: up – down, this life – afterlife in the context of the Axis Mundi idea. Four suns as part of the plot of the painted cist demonstrate the non-static solar nature, its four states, and, consequently, suggests the solar myth that has a spatio-temporal realization.

Results. The cosmological picture of the world of the Kemi-Oba people includes the processes of categorization of the environment objectified through the fragmentation of the path of the sun, i.e. duality and quaternary.
Materials for the Study of Items from Non-Ferrous and Precious Metals of Selitrennoe Settlement: Chemical Composition
Authors: Kovaleva Kseniya
Published: October 2020

Introduction. This paper presents the results of the study of the chemical composition of nonferrous and precious metal items from the excavations of the Selitrennoe settlement by the Volga Region Archaeological Expedition in 1986–1989 stored in the State Historical Museum.

Methods and materials. XRF was used as a method of determining the elemental composition; the main technological operations were determined using the trasology method. A total of 63 subjects were analyzed, including domestic items, jewelry and items related to production.

Analysis and Results. The alloys have been distinguished depending on the presence and concentration of alloying elements: brass (two-component, tin, lead, multicomponent), bronzes (tin, lead, leadarsenic, tin-lead, tin-zinc, and multicomponent) and silver alloys (multicomponent high silver bronzes and goldsilver alloy). Inclusions of soldering with silver in the solder and gilding according to the amalgamation have been also recorded. The results of the analysis show the prevalence of two-component brass and multicomponent alloys, a small amount of tin bronzes and the complete absence of items from “pure” metals – copper, tin and lead. The common practice of using recycled metal can be judged by the relatively low content of zinc in brass and a large proportion of multicomponent alloys. Despite the presence of distinguishable stable groups, a wide range of concentrations suggests the absence of clear recipes, including for certain categories of objects. The dependence of the applied technology on the composition of metal is also revealed. The sample of the Selitrennoe settlement is significantly different from other large series of analyses of the Golden Horde time (Bolgar Region, Uvek and its neighborhood).
On the Time When Using Hunting Birds Appeared in Traditional Cultures of Eurasia
Authors: Lukyashko Sergey
Published: October 2020

Introduction. The popularity of images of birds of prey in Scythian art makes us pay more attention to the place of birds of prey in the life of the Scythian world. Birds of prey were actively used in the hunting practice, and hunting with hunting birds was an elite form of hunting common in open spaces.

Materials. The first information about nurseries of hunting birds belongs to ancient China of the 7th century BC. Images of hunting birds appear on Hittite basreliefs of the 13th century BC. They are also known in the Assyria of the time of Sargon II.

Analysis. The active participation of the Scythians in political events in the Middle East allows us to assume that the Scythians are familiar with this method of hunting. In Scythian culture, there are a series of images of attacking birds, which should be seen as naturalistic sketches.

Results. The abundance of bone remains of hunting birds in the cultural layers of Scythian settlements and the presence of a burial of a man with a Falcon in the materials of the Elizavetovskoe hillfort directly indicates the use of hunting birds in the South Easten European continent steppe as early as the 4th century BC.
Utopia, ensaio e tempestade: o novo mundo em Morus, Shakespeare e Montaigne
Authors: Villas Bôas Luciana
Published: October 2020

Resumo Este artigo faz uma exploração de utopias letradas transmitidas ao longo de século XVI e início do XVII, enfocando um elemento específico das elucubrações humanistas: a ficção de encontros utópicos entre os mundos antigo e novo na Utopia de Thomas Morus, na Tempestade de Shakespeare e os Ensaios de Michel de Montaigne. Esses ‘encontros’ são, de fato, uma instância privilegiada de um imaginário político cuja articulação entrelaça a realização de um projeto humanista renascentista ao espaço recém-descoberto. Os ecos de Montaigne na Tempestade de Shakespeare são o ponto de partida para a investigação de aspectos controversos do imaginário político humanista renascentista em relação ao Novo Mundo e à colonização europeia.
Aparatos residuales: Cosmococas y Navilouca
Authors: Kogan Adriana
Published: October 2020

Resumen El presente trabajo se propone reflexionar acerca de los modos de relación que cierta zona del arte experimental brasileño de los años setenta propuso con respecto a la cultura de masas. La hipótesis central del texto es que la relación de reinscripción del arte con respecto a la cultura de masas funciona como un modo a través de los cuales el arte ejerce su antagonismo con respecto a lo social, basándose en la alteridad y en la resignificación de la exclusión que el Estado propicia a través de la censura. Para sostener esta hipótesis, el trabajo analiza las Cosmococas de Hélio Oiticica y Neville D’Almeida, y la revista Navilouca a partir de la relación con el residuo que cada obra propone. A partir de la distinción de estos dos modos posibles de relación con el residuo, se presenta el concepto de aparatos residuales, que es definido como una modalidad de vínculo a través del cual el arte experimental produjo la incorporación de los restos y desechos de la cultura de masas.
Effect of surface bugholes on chloride penetration of concrete coated with penetrants
Authors: Hu Liangjun , Yoshitake Isamu , Sayama Masayuki , Sayama Shoichi
Published: October 2020

Bugholes, considered an aesthetic problem, generally appear on concrete surfaces. Such surface imperfections may accelerate the ingression of liquids and chlorides. Chloride penetration is of crucial concern for reinforced concrete in a saline environment. Various surface penetrants have been widely used to protect concrete from environmental corrosion. However, most previous research on penetrants was conducted on concrete with minimal surface imperfections, such as bugholes or cracks. These surface blemishes bring worries about the protective effect of surface penetrants for concrete that may degrade. Surface finishing before coating increases construction costs and duration. This study focuses on the impact of surface bugholes on chloride penetration of concrete coated with surface penetrants. The surfaces of specimens have various sizes of bugholes. Specimens were immersed in a sodium chloride solution of 3% for 100 days. The test results show that silane-based penetrants have an excellent water-repellent effect even on a concrete surface with bugholes. The chloride penetration depth increased with increasing surface bughole size when the concrete surface was uncoated or coated with a low-water-repellent surface penetrant. For concrete surface treated with high-water-repellent surface penetrants, the influence of surface bugholes on chloride penetration was negligible.

Authors: Apple-Chiarella Vince , Vargas Tiffanye , Madrigal Leilani
Published: October 2020

The purpose of this study was to assess the continuing education preferences of soccer referees registered with the United States Soccer Federation. Participants completed a Likert-type survey consisting of 18 topics asking them to rank how helpful they would consider each topic for continuing education. Results indicated that referees considered player management, using personality to manage games, and the decision making process as the most important topics for continuing education.  Administrative duties and handling were considered the least important topics.  There were no significant differences in perceptions of importance when comparing referee experience levels.  These findings suggest that referee curriculum should be reviewed and revised according to referee preferences.
College athletes and the influence of academic and athletic investment on sense of belonging
Authors: Huml Matt R , Gellock Jennifer L , Lecrom Carrie W
Published: October 2020

While the athletic and academic experiences of student-athletes have been frequently examined by scholars (Houle & Kluck, 2015; Rettig & Hu, 2016), there is a lack of research into which investment creates a sense of belonging on campus for student-athletes. Other factors, such as sport status, have only been conceptually discussed, while transfer status and gender, have been examined in non-athlete populations, highlighting a gap in our college student understanding of sense of belonging. We used structural modeling to examine the relationship between athletic investment, academic investment, and demographics within a context of student-athletes. Results indicated as both athletic and academic investment increase, the student-athlete’s sense of belonging on campus decreased. Additionally, student-athletes who were transfers, in team sports, or men were more likely to have a reduced sense of belong on campus.

Published: October 2020

En el trabajo se analizan las arbitrariedades de la censura durante el franquismo y se señala cómo las obras de José Jiménez Lozano constituyen un desafío a los mismos presupuestos censores: sus historias muestran las consecuencias de usar la autoridad como freno a la libertad, así como la irreductibilidad de una conciencia libre. Se hace a partirde una colección de cartas inéditas sobre la escritura del autor de 1960. En ellas se descubrela confusió n de las advertencias que, a instancias de la autoridad eclesial, realiza la autoridad política sobre sus artículos. En segundo lugar, se analizan los expedientes de la censura sobre las tres primeras novelas del escritor: Historia de un otoño (1971), El sambenito (1972) y La salamandra (1973), los tres conservados en el Archivo General de la Administración. La censura conmina a mantener una imagen de España con fe y pensamiento únicos.

Adatok a Duna Komárom-Esztergom és Fejér megyei szakaszainak flórájához
Authors: Riezing Norbert
Published: October 2020

A cikk elsősorban a Duna árterének vízi és iszapnövényzetével foglalkozik. Az adatok többnyire a 2019-es, tartósan alacsony vízállás mellett végzett felmérések eredményeit tükrözik. A Komárom-Esztergom megyei szakasz iszapnövényzete viszonylag jól kutatottnak számít, míg a Fejér megyei korábban alig volt ismert. A vizinövények közül a Gönyű és Neszmély közötti szakaszról korábban ismert, egyébként is ritka Hippuris vulgaris és Hydrocharis morsus-ranae nem került elő. Megjelent viszont több veszélyes özönnövény, így a Salvinia molesta, Myriophyllum aquaticum, Limnobium laevigatum, valamint a Crassula helmsii, melynek ez az első hazai adata. Hosszú évtizedek után ismét előkerült a Vallisneria spiralis, jelen van az Elodea canadensis, illetve egyre elterjedtebb az Elodea nuttallii és az Azolla taxonok. Az iszapnövényzetben új fajként jelent meg, sőt meglehetősen elterjedt lett a Lindernia procumbens és az adventív Lindernia dubia. Özönnövények közül megjelent a Cyperus esculentus, az Euphorbia maculata és az Eleusine indica. A korábban ismerthez képest jóval elterjedtebb lett a Veronica catenata és a Schoenoplectus triqueter, valamint nagyobb állományai vannak a Cyperus glomeratus-nak. A nyílt kavicsos felszínek érdekes növénye a több lelőhelyen is megtalált Polygonum graminifolium, melynek egészen a közelmúltig nem voltak aktuális hazai adatai.

Published: October 2020

The epidemiological control of diseases communicable through the vaccine represented a great revolution in science and in the history of public health. The theme is related both to the orbit of the individual right to health, and to the collective right to health of all, since it is a disease preventive health policy.Advances in medicine in research and development of new vaccines will be of no use if there is no collective adherence by society to vaccination campaigns. On the other hand, the State cannot only hope that this adhesion occurs in a conscious and voluntary way, at times, it will have to assert its leadership to protect the right to health of the community.
Synchronization of the Electric Power Network in the Conditions of High-Frequency Measurement Noises
Authors: Furtat I. B. , Nekhoroshikh V. N. , Gushchin P. A. , Chugina Y. V.
Published: October 2020

The problem of robust synchronization of the electrical power network with unknown parameters is considered in the present paper. The load angles of each generator with superimposed additive high frequency noises are available for measurement. An algorithm has been synthesized to reduce the influence of noises on measurement signals and to ensure synchronization of the network in normal mode and in emergency situations associated with a sudden change in the conuctivity of power lines. To synthesize the control algorithm, the new approach is used which makes it possible to independently control the quality of noise filtering and the quality of the stabilization error of the output variable. The conditions guaranteeing the stability of the system are obtained. The simulation results have shown that the designed control system of a network of electric generators, when only noisy indications of load angles are available for measurement, provides better transient quality indicators compared to schemes of R. Ortega (France) and D. Hill (Australia), where the entire state vector is available to measurements and the parameters of the generator model are partially known. Modeling also showed that the proposed algorithm ensures the stability of a closed-loop system if there are unmodeled dynamics in network model. We also note that under conditions of random measurement noises, the control goal cannot be guaranteed due to the unlimited nature of the noises, however, the simulation results illustrate the satisfactory quality of transients with nonzero random signals in noises.

Published: October 2020

The article is devoted to priority solutions for launching systemic transformations of managerial education for the technological breakthrough. The basis for the development of such decisions was the scientific direction “Proactive Management in Actively Developing Industries and Economic Sectors”, in which the authors work, and the experience in creating educational products that meet the latest trends, including those that have appeared recently.

The research methodology included analysis of scientific literature on the problems of complex systems development, proactive management and anticipatory training, systematization of educational practices for managers in foreign and domestic universities, conducting surveys of experts – heads of Russian large industrial enterprises, professors and students.

The key reasons for the unsatisfactory state of management education are identified and a set of recommendations for its reform has been developed. Changes in organizational models of managerial education are proposed, the principles of implementing fundamental training and enhancing the humanization of education with a simultaneous increase in the level of knowledge of the scientific and technical foundations of production process are formulated. The conditions of increasing the effectiveness of students' practical training are considered, the forms of its implementation are determined to ensure the readiness of graduates to work in managerial positions. The results of long-term studies of anticipatory training, from managers at the lower levels to directors of large companies, are carried out.

Technical Ceremonies: Rationalization, Opacity, and the Restructuring of Educational Organizations
Authors: YURKOFSKY MAXWELL M.
Published: October 2020

After decades of accountability and market-based reforms in education, school systems are now organizing more around improving teaching and learning. Yet these efforts frequently yield unintended, superficial, or even counterproductive changes at the school level. In this article, Maxwell Yurkofsky develops the concept of technical ceremonies as a way of theorizing this emerging pattern of school organizations. Technical ceremonies involve educators changing their practice to align with new reforms in a way that privileges what is visible and measurable as a way of appeasing external stakeholders over more substantive improvements to practice. He argues that technical ceremonies arise as principals navigate a multitude of surface-level demands from the environment and the uncertainties that pervade efforts to transform teaching and learning.

Foot abduction brace noncompliance in children with idiopathic clubfoot: how the deep squatting posture might help
Authors: Sailohit Pipattra , Limpaphayom Noppachart
Published: October 2020

Background. Compliance with the foot abduction brace (FAB) is essential for idiopathic clubfoot (ICF) managed by the Ponseti method. The deep squatting posture (DSP) was correlated with favorable outcomes in ICF.
Aim. The aims of the study were to identify the noncompliance rate with the FAB, and assess how the routine practice of ankle stretching and Asian-style DSP affected the ICF correction during the Ponseti method.
Materials and methods. Of 42 children with ICF, 63 ICF underwent the Ponseti method at an average age of 8.7 12.6 weeks using an average of 5.4 1.7 casts followed by FAB wear. The children practiced the DSP exercise as an adjunct to the FAB protocol. Children noncompliant with the FAB protocol but compliant with the DSP exercise (group A) were compared with children noncompliant with both FAB protocol and DSP exercise (group B).
Results. At an average follow-up of 3.5 1.4 years, 8 of 42 children compliant with the FAB protocol. The FAB protocol deviation was documented at an average of 10.3 4.8 months. Children who did not adhere to the practice of the DSP exercise had a higher recurrent rate of any ICF deformity (OR 7.82, 95% CI 1.3553.79, p = 0.003). Of the 34 children (48 feet) noncompliant with FAB, the children in group A (39 feet) had lower recurrence rate (p = 0.02), a better Dimeglio grade (p = 0.005), and a better Pirani score (p 0.001) at the most recent evaluation than children in group B (nine feet). However, recurrent metatarsus adductus was more prevalent in group A.
Conclusion. The DSP exercise should be advocated as a supplemental modality but cannot substitute the regular use of FAB.

Background. The relative overgrowth of the greater trochanter is one of the most common deformities of the proximal femur in association with several disorders of the hip joint.
Aim. To analyze the dynamics of proximal femoral growth after trochanteric epiphysiodesis as well as to determine the options for using this method in the complex treatment of children with hip pathology.
Materials and methods. We analyzed the data of clinical and radiological examinations and surgical treatment (permanent trochanteric epiphysiodesis with metal fixation) outcomes for 43 (52 joints) patients aged 412 years with a developing high position of the greater trochanter.
Results. The surgery enabled slowing down of the growth of the greater trochanter on the side of intervention by (average) 50% (p 0.05), although the values of the neck-shaft angle both on the affected side and the side opposite to it did not change (p 0.05).
Conclusion. In moderate disorders of the growth plate of the femoral head epiphysis, trochanteric epiphysiodesis can prevent the progression and, in some cases, correct disturbed ratios of the hip joint, thereby avoiding the need for larger surgical interventions.

Published: October 2020

Background. A large number of studies have focused on automating the process of measuring the Cobb angle. Although there is no practical tool to assist doctors with estimating the severity of the curvature of the spine and determine the best suitable treatment type.
Aim. We aimed to examine the algorithms used for distinguishing vertebral column, vertebrae, and for building a tangent on the X-ray photographs. The superior algorithms should be implemented into the clinical practice as an instrument of automatic analysis of the spine X-rays in scoliosis patients.
Materials and methods. A total of 300 digital X-rays of the spine of children with idiopathic scoliosis were gathered. The X-rays were manually ruled by a radiologist to determine the Cobb angle. This data was included into the main dataset used for training and validating the neural network. In addition, the Sliding Window Method algorithm was implemented and compared with the machine learning algorithms, proving it to be vastly superior in the context of this research.
Results. This research can serve as the foundation for the future development of an automated system for analyzing spine X-rays. This system allows processing of a large amount of data for achieving 85% in training neural network to determine the Cobb angle.
Conclusions. This research is the first step toward the development of a modern innovative product that uses artificial intelligence for distinguishing the different portions of the spine on 2D X-ray images for building the lines required to determine the Cobb angle.
Surgical treatment outcome of wrist flexion contracture in children with cerebral palsy through temporary extra-articular arthrodesis

Published: October 2020

Background. The surgical approaches adopted for the treatment of wrist flexion contracture can be categorized into soft tissue intervention (such as lengthening or transplantation of tendons) and bone operations that stabilize the wrist joint. We developed a technique for temporary arthrodesis of the wrist joint to combine the main advantages of both the approaches, that is, the stability of arthrodesis by the installed metal construction and the possibility of active movements in the wrist joint after removal of the structure.
Aim. To compare the effectiveness of a new method of surgical treatment of wrist flexion contracture in children with cerebral palsy, such as temporary extra-articular arthrodesis and transplantation of the hand flexors to the extensors, according to Green.
Materials and methods. We conducted a comparative analysis of the treatment outcomes between the following 2 groups of patients: group 1 (n = 13) patients underwent a tendon transplantation of m. flexor carpi ulnaris on m. extensor carpi radialis brevis/longus (Green operation), while group 2 (n = 13) patients underwent temporary arthrodesis of the wrist joint with a bone plate for a period of 1 year. The patients in group 2, after the removal of metal structures, underwent a 14-day course of rehabilitation before evaluation of their treatment outcomes. A comparative analysis of the treatment results between the groups 1 and 2 was performed 1 year after arthrodesis and plate removal and at 1 year after muscle transplantation. The range of active and passive movements in the wrist joint was analyzed throughout. In addition, the functionality of the upper limb was assessed with reference to the international classification system of MACS 2002 and the Block and Box test.
Results. In the group 1 patients, an increase in the passive range of motion (+9.7) was noted. In both the groups, a significant increase was recorded in the amplitude of active movements (31.9 in group 1 and 45.7 in group 2). The upper limb functionality index MACS, on evaluating the condition of the arm as a whole, appeared to be almost identical in both the groups. In the group 1 patients, the average dynamics of the Block and Box test as a result of treatment was 8 additional cubes, while it was only 1.6 in the group 2 patients.
Conclusion. The Green operation was less effective in comparison with the operation of temporary arthrodesis as a method of correcting the flexion contracture of the wrist joint. However, the functional performance of the Green operation was higher. The choice of the optimal surgical treatment technique can be determined as follows. In children with a high functional perspective, the Green operation is preferred. However, in children with doubtful functional prospects where the correction of severe contracture is the main aim, temporary arthrodesis may be preferable.

Background. Abducto-plano-valgus foot deformity is one of the most common diseases affecting children and teens. Recently, various methods of surgical treatment have been proposed for the same. However, despite the availability of various operational methods, there are several contradictions in the feasibility and success of a particular operation.
Aim. To improve the technique of Evans Calcaneal osteotomy through the use of customized heel bone fixators.
Materials and methods. A total of 30 patients (42 feet) aged 915 years with abducto-plano-valgus foot deformity were included. We undertook clinical examination, X-ray, computed tomography, and experimental researches. The surgical treatment consisted of Evans Calcaneal osteotomy, with the use of the standard method of fixation in group 1 (n = 33 feet) and the use of a customized fixator in group 2 (n = 9 feet).
Results. The improved technique of Evans Calcaneal osteotomy using a special customized fixator allowed making the necessary correction in 100% of cases. The period of restoration of the heel bone integrity was reduced by an average of 30% (p 0.05). The period of restoration of the support became faster by almost 45% (p 0.05).
Conclusion. The use of a special customized fixator for Evans Calcaneal osteotomy could significantly improve the outcomes and shorted the treatment time for children with abducto-plano-valgus foot deformity.
