Authors: Hu Jie , Chen Hua , Yu Yonggang , Xue Xiaochun , Feng Zhiwei , Chen Xiaojun
Published: April 2023

As a damage element, high-speed fragments have a significant effect on the ammunition safety. The impact from the fragments are also one of the basic problems of ammunition safety tests. To clarify the reaction characteristics of combustion, explosion, detonation, and so on, when hypersonic fragments hit insensitive munitions, it is necessary to carry out corresponding research on the deceleration law of hypersonic fragment in the air. In this paper, a 30 mm caliber gun with large chamber, small caliber, and large aspect ratio is proposed to drive high-speed fragments. According to STANAG 4496 standard, a near-cylinder steel fragment with Brinell hardness HB ≤ 270 and mass of 18.6 g was designed. The test system was composed of zone interception velocity measurement, chamber pressure sensor, trajectory tracking system, high-speed camera, and other equipment were also established to obtain the pressure variations in the chamber, the velocity of the fragment, and its flight orientation. From the video taken by the high-speed camera and trajectory tracking system, the fragment and the projectile sabot achieve effective separation after the fragment travels out of the muzzle. As time goes on, the distance between the fragment and the projectile sabot gradually increases. The fragment is always in the front of the sabot and steadily flies to the target. The muzzle velocity of the fragment is controlled by adjusting the propellant charge, and the flight velocity in the air is measured by the zone interception velocity measuring device in the range of 5 Ma to 7 Ma. The theoretical models of fragment deceleration and the models of flight orientation are also established according to the experimental data. On this basis, F test and least square nonlinear regression fitting were used to analyze experimental data. Finally, the deceleration coefficient of quasi-cylindrical fragments between 5 Ma and 7 Ma stipulated in STANAG 4496 standard is 0.009312, and the average drag coefficient in air is 1.109.

Authors: Xie Yi , Zhou Lingke
Published: April 2023

With the promotion of the dual carbon policy and the process of transforming and upgrading manufacturing, vigorously developing high-tech manufacturing with high-technology content and significant added value has become a powerful driving force to improve the development of the regional economy. In this regard, this research employs the two-stage network SBM-DEA method with undesirable outputs and multi-stage activities involved in the green production process. We examine the green technology innovation efficiency of high-tech manufacturing in the Yangtze River Delta (YRD) region from 2010 to 2020. We divide the activities of the high-tech manufacturing industry into two sub-stages, namely, the research and development (R&D) stage and the result transformation stage. The results are as follows: (1) The efficiency level of green technology innovation in Shanghai is at an outstanding level, having the most significant performance both in the R&D stage at 0.833 as well as in the result transformation stage at 1.006. (2) Anhui’s green technology innovation efficiency is mainly driven by the R&D stage. Green technology innovation efficiency in Jiangsu province depends primarily on the stage of result transformation, but there is still room for improvement in resource allocation. (3) Zhejiang needs to catch up in both the R&D stage and the result transformation stage, as well as to optimize the resource allocation of the green technology innovation process.
A Laborer’s Mask-Wearing Behavior Detection Approach in the Manufacturing Field
Authors: Hung Yu-Hsin
Published: April 2023

Industry 4.0 has considerably advanced multiple manufacturing fields through digitalization and intelligentization. Many technologies, such as supervisory control, data acquisition, and data analytics, have been used widely in manufacturing sites to enhance production efficiency. Therefore, this created a cloud-based anomaly detection module for epidemic prevention at the manufacturing site. Image process technologies, deep learning algorithms, and cloud computing were employed in the proposed module to automatically identify labor anomaly behavior in the manufacturing site and prevent the epidemic. This study used image processing technologies and deep learning to recognize and train the manufacturing site image. Accordingly, the analyzed result could be incorporated into the cloud system using the Message Queuing Telemetry Transport (MQTT) protocol. Therefore, the administrators and laborers can be notified regarding the anomaly behavior. The author used the image data obtained from the cylinder head process site as a data source for DA. As per the experimental results, the proposed method has an accuracy of 90%. Therefore, deep learning algorithms provide a practical approach to anomaly detection for epidemic prevention. Furthermore, this study’s primary contributions are designing an improved approach and connecting the manufacturing site to the cloud side using the proposed module.
A Novel High-Voltage Gain Step-Up DC–DC Converter with Maximum Power Point Tracker for Solar Photovoltaic Systems

Published: April 2023

In order to generate electricity from solar PV modules, this study proposed a novel high-voltage gain step-up (HVGSU) DC–DC converter for solar photovoltaic system operation with a maximum power point (MPP) tracker. The PV array can supply power to the load via a DC–DC converter, increasing the output voltage. Due to the stochastic nature of solar energy, PV arrays must use the MPPT control approach to function at the MPP. This study suggests a novel HVGSU converter that uses the primary boost conversion cell and combines switched capacitors and voltage multiplier cells. The proposed topology is upgradeable for high-voltage gain step-up and can be incorporated as well. A clamp circuit reuses the energy that leaks out so that the switch voltage stress and power loss are kept to a minimum. One thing that makes it stand out is that the voltage stress on the diodes and switch stays low and constant even as the duty cycle changes. Additionally, the inductor greatly reduces the diodes’ reverse recovery losses. There is a lot of information about steady-state analyses, operation principles, and design guidelines. A prototype circuit is built to test the maximum power point tracking operation with voltage conversion from 20–40 V to 380 V at 150 W. The results of the experiments support the theoretical analysis and claimed benefits. The proposed converter has the ability to track the maximum power point and a high conversion efficiency over a wide range of power. A weighted efficiency of 90–96% is shown by the prototype.
Effect of Rosehip Powder Addition on Dough Extensographic, Amylographic and Rheofermentographic Properties and Sensory Attributes of Bread
Authors: Vartolomei Nicoleta , Turtoi Maria
Published: April 2023

One of the improvers used in breadmaking is ascorbic acid (AA), a chemical compound that strengthens the dough and extends the shelf life of bread. This work investigates the suitability of replacing the synthetic AA with rosehip powder (Rp) rich in this bioactive compound. Thus, a comprehensive study of wheat flour (WF) replaced with 0.5–2.5% w/w Rp regarding the extensographic, amylographic and rheofermentographic properties of dough and sensory attributes of bread was performed. WF without RP or AA addition of 2 mg/100 g was used as a control. A sample with an AA addition of 2 mg/100 g was also used. The Rp addition positively influenced the extensographic, amylographic and rheofermentographic properties of the dough. The dough resistance to extension, R, in Brabender Units (BU), increased from 330 ± 1.41 BU (control) to 995 ± 1.41 BU (2.5% w/w Rp) for a resting time of 90 min. The gelatinization temperature of the dough increased from 61.0 °C (control) to 62.9 °C (2.5% w/w Rp). The volume of gases retained in the dough increased in bread with up to 2.0% w/w Rp and afterwards decreased. The sensory properties of the bread, e.g., external appearance, volume, flavor, and taste, were appreciated by the sensory panel and received higher total scores than the control bread. According to the results presented in this work, the optimum concentration of Rp was 1.5% w/w. However, because the concentration of AA in Rp at the moment of use could vary, it would be better to consider an optimum range, e.g., 1.0–2.0% w/w Rp. The study showed that the Rp is appropriate for breadmaking as an alternative to synthetic AA.
Effect of Drying Pretreatment on Cellulolytic Enzymatic Hydrolysis of Lignin from Napier Grass
Authors: Saadon Syazmi Zul Arif Hakimi , Osman Noridah Binti
Published: April 2023

Biomass can be a viable supplement and alternative to non-renewable sources of fuel and chemicals. Lignin is an important part of biomass sources which can be used in various chemical and fuel industries. This study explores the pretreatment of lignin from Napier grass using thermal and physical means, as well as extraction of lignin via cellulolytic enzymatic hydrolysis to determine the optimum condition for feedstock pretreatment. Napier grass parts under various drying conditions and particle sizes were treated with enzymes. Moisture analysis, FTIR spectroscopy, UV–Vis analysis, and Klason lignin were carried out to analyze the moisture, functional group, and yield of lignin. Moisture content of the samples were inversely proportional to the drying conditions. The FTIR result showed lower peak intensity for higher drying conditions, while ball-milling showed less reduction in peak intensity. More Klason lignin was extracted under higher drying conditions. The yield of cellulolytic enzymatic lignin (CEL) was found to be more than actual lignin content, suggesting cellulose was not fully degraded. The FTIR spectra of CEL was found to be closer to that of lignin, but purification was still needed. Optimization was carried out by evaluating the statistical significance of each pretreatment effect of the pretreatments.

Frequent sprays on cotton prompted resistance development in the tarnished plant bug (TPB). Knowledge of global gene regulation is highly desirable to better understand resistance mechanisms and develop molecular tools for monitoring and managing resistance. Novel microarray expressions of 6688 genes showed 3080 significantly up- or down-regulated genes in permethrin-treated TPBs. Among the 1543 up-regulated genes, 255 code for 39 different enzymes, and 15 of these participate in important pathways and metabolic detoxification. Oxidase is the most abundant and over-expressed enzyme. Others included dehydrogenases, synthases, reductases, and transferases. Pathway analysis revealed several oxidative phosphorylations associated with 37 oxidases and 23 reductases. One glutathione-S-transferase (GST LL_2285) participated in three pathways, including drug and xenobiotics metabolisms and pesticide detoxification. Therefore, a novel resistance mechanism of over-expressions of oxidases, along with a GST gene, was revealed in permethrin-treated TPB. Reductases, dehydrogenases, and others may also indirectly contribute to permethrin detoxification, while two common detoxification enzymes, P450 and esterase, played less role in the degradation of permethrin since none was associated with the detoxification pathway. Another potential novel finding from this study and our previous studies confirmed multiple/cross resistances in the same TPB population with a particular set of genes for different insecticide classes.

To date, many fluorescence- and gel-based multiplex polymerase chain reaction (PCR) assays have been developed for the simultaneous detection of multiple infectious agents of respiratory disease in poultry. However, PCR assays are not available for other important emerging respiratory bacteria, such as Ornithobacterium rhinotracheale (ORT). We aimed to fill this gap by establishing a new duplex PCR method for the simultaneous detection of infectious laryngotracheitis virus (ILTV) and ORT. Multiplex primer design software was used to select the compatible multiplex primer pairs. It was determined that an annealing temperature of 65 °C and an initial concentration of 2.5 pmol/µL for each primer set were the most suitable conditions for multiplex PCR. The assay was confirmed to be specific, as it only detected the target pathogens, even in the presence of six non-target agents. The limit of detection was up to 103 copies/µL of template DNA for both ILTV and ORT. In the screening of 304 field samples, 23, 88, and 44 were positive for both ILTV and ORT, solely for ILTV, and solely ORT, respectively.
Reduction in Rumen Tetracycline-Insensitive Bacteria during a Grain Challenge Using the Isoflavone Biochanin A
Authors: Flythe Michael D. , Davis Brittany E. , Kagan Isabelle A.
Published: April 2023

The isoflavone biochanin A was previously shown to promote weight gain in growing steers by selectively inhibiting rumen bacteria-like growth-promoting feed antibiotics. The hypothesis that biochanin A inhibited the action of drug efflux pumps was tested by enumerating tetracycline-insensitive bacteria from steers in a subacute rumen acidosis (SARA) challenge. Steers (n = 3/group) treatment groups were forage only, SARA control, SARA with monensin (0.2 g d−1), and SARA with biochanin A (6.0 g d−1). As the steers were stepped up from the forage-only basal diet to 70% cracked corn, the number of rumen bacteria enumerated on two tetracycline-containing media types (nutrient glucose agar and tetracycline, and bile esculin azide and tetracycline) increased (p < 0.05) from as little as 1.7(105) to as great as 6.7(106) cfu mL−1 on the nutrient glucose agar in the SARA and monensin control groups. The biochanin A group maintained the same number of tetracycline-insensitive bacteria as the forage-only controls (p > 0.05). The effects were similar to the more selective media type, but the differences were smaller. These results support the hypothesis that biochanin A inhibits the activity of drug efflux pumps in vivo.

Purpose: To summarize the characteristics and trends of interest in retinoblastoma (Rb) in the last 50 years. Methods: The Web of Science Database was used to find all studies focused on Rb published from 1970 to 2018. The term “retinoblastoma” was used to search for the 100 most cited records. Results: The mean number of citations was 153.55 ± 88.9. The majority were from the United States (US) (n = 68). Drs. Shields authored 38% of the papers. The number of citations per year was positively correlated with the number of authors, r = 0.26 (p = 0.008). The number of patients was significantly associated with the number of citations per year (p = 0.012). Although papers on radiotherapy were the most common, publications about intra-arterial chemotherapy (IAC) were associated with 88.3% more citations per year (p = 0.031) and papers on intravenous chemotherapy (IVC) were associated with 40.3% more citations per year (p= 0.04). Review and meta-analysis studies had a higher median of citations (10.5) than interventional (6.4) or observational (5.2) studies. Conclusions: This study compiles a comprehensive analysis of the most-cited articles on Rb. Studies with a higher number of citations per year were associated with IAC, which emphasizes the significance of the advances in Rb treatments that allow for the saving of eyes and vision as well as lives. Review studies had more citations than observational or interventional studies. More citations were associated with a larger number of authors or more reported patients per paper. These findings highlight the importance of collaborations to achieve relevant, high-quality research of Rb.

Published: April 2023

Over the past 15 years, the fuel and energy complex of the Russian Federation has undergone significant systemic and structural changes. The need to implement changes is dictated by external challenges from the global energy markets, in the functioning of which the Russian economy plays a key role, as well as internal challenges, emerging in the form of requests from all sectors of the economy for the need to reduce the cost of consumed energy resources, and the need to increase the efficiency of the economy. Since 2006, a wholesale electricity (capacity) market has been operating in Russia, the mechanisms of which are based on the principle of competitive pricing for electricity supplied to consumers. Participation in the wholesale market for industrial enterprises opens up the possibility of reducing the cost of purchasing electricity, in the form of excluding the payment for the services of regional guaranteeing suppliers, whose share can range from 3% to 8% of the final electricity tariffs. Positive experience in creating competitive relations in the electric power industry determined the possibility for introducing energy market mechanisms into the Russian gas supply industry. In 2014, competitive natural gas trading was launched in Russia as part of the Commodity Exchange, in which large consumers and independent suppliers can participate.

Published: April 2023

Los migrantes retornados se enfrentan a dificultades de reintegración laboral, por ello, el objetivo de esta investigación fue conocer la influencia de la experiencia laboral en la intención emprendedora del migrante retornado de Estados Unidos en el municipio de Puebla, México. Este análisis se basó en la Teoría del Comportamiento Planificado, considerando como variable dependiente a la intención emprendedora y como variables independientes a la norma subjetiva, al control de comportamiento percibido y a la actitud conductual; así como también, a la experiencia laboral. La metodología empleada tuvo un enfoque cuantitativo de tipo correlacional causal y diseño no experimental. Los resultados destacaron que los migrantes retornados encuestados muestran actitud positiva frente a la intención emprendedora y se demostró que la experiencia laboral adquirida en Estados Unidos se relaciona negativamente con el emprendimiento. Una limitante de esta investigación es su alcance, ya que se realizó el estudio en una zona geográfica especifica; además, no se diferencia el tipo de retorno del migrante, por lo que sus resultados se deben de tomar con cautela. La originalidad de este trabajo radica en el uso de la Teoría del Comportamiento Planificado para analizar la influencia de la experiencia laboral en la intención emprendedora del migrante retornado.

Published: April 2023

Este trabajo investiga si existe discriminación salarial hacia los trabajadores hombres migrantes internos en México. Para ello, se realiza un análisis de descomposición de Blinder-Oaxaca en la media y por decil de ingreso, utilizando la Encuesta Nacional de Ingreso y Gasto de los Hogares (ENIGH) del 2020 y controlando por el problema de autoselección de los migrantes. Se encuentra que, aunque los migrantes internos reciben (en promedio) salarios 5.5% mayores que los trabajadores no migrantes, si recibieran salarios similares a los no migrantes de acuerdo con sus características observables y autoselección, los migrantes internos deberían recibir (en promedio) salarios 15.3% mayores que los no migrantes. También se encuentra que son los trabajadores migrantes más pobres y aquellos que llegan a las regiones centro y sur-sureste del país, los que registran mayores niveles de discriminación salarial. Dada la limitación de los datos, no es posible considerar el tiempo de migración, la asimilación de habilidades o la migración de retorno.

Nicolas Duruz, Las representaciones populares de lo "mental".

En esta investigación, el autor pone en evidencia una tipología de las representaciones populares de "la actividad mental". Sobre la base de 60 entrevistas conducidas acerca de una población no "psi", interpretados según un análisis de contenido comprensivo y no cuantitativo, el autor clasinca las representaciones en función de dos dimensiones : la intensidad de la actividad mental (dinámica vs estática) y su polaridad referencial (independencia vs dependencia de la realidad externa). Este estudio reposa sobre el postulado que el profesional "psi", tanto por razones éticas que de eficadidad, debe tener en cuenta en su trabajo con sus clientes a con sus pacientes de las "teorías subjetivas" de las cuales estos disponen para representar y explicar su problema. En función de esta tipología, cuatro perfiles de clientes tipo son esbozados con el fin de ayudar el profesional a ajustar mejor sus estrategias de intervención.

Les enfants battus : un dévoilement difficile
Authors: Selosse Jacques
Published: April 2023

Après quelques romanciers du 19ème siècle, ce sont les médecins légistes en France et les pédiatres américains qui ont attiré l'attention des cliniciens sur les enfants battus. Il a fallu près d'un siècle, un procès retentissant et le support technique de la radiographie pour révéler et convaincre de la réalité des sévices familiaux. La durée de ce dévoilement invite à s'interroger sur la nature des résistances et des défenses qui ont freiné la reconnaissance puis le traitement de cette forme particulière de violence.

Dans ce bref article introductif sont exposés succinctement quelques considérations sur l'étiologie complexe et interactive de la violence intra- familiale, sur la spécificité des rapports au corps de l'enfant réel, sur la réalité du traumatisme non accidentel, sur l'introjection de l'agresseur et l'inclusion réciproque dans l'expérience primitive du corps à corps. En conclusion, quelques réflexions sur les critères déontologiques des intervenants sont évoquées.

Une mère battue : du réel au fantasme
Authors: Boekholt Monika
Published: April 2023

Ce travail porte sur le fonctionnement psychique des enfants qui, hors contexte psychotique avéré, maltraitent leurs parents et en particulier leur mère. Après une incursion dans la littérature relative aux dénominateurs communs des conduites agressives dans lesquelles s'insèrent la plupart de ces maltraitances, la question de la spécificité des représentations et des affects sous-jacents est traitée à travers une étude de cas. Contrairement aux attentes, la clinique projective met en évidence une intense activité fantasmatique que les ressources défensives indigentes s'emploient à museler ; l'agir agressif tient alors lieu de rapproché incestueux et combat le risque dépressif de perte, essentiels dans la problématique.

Neuropsychologie et schizophrénie
Authors: Crombecque Alain , Osiek Christian
Published: April 2023

Alain Crombecque y Christian Osiek, Neuropsicología y esquizofrenia.

Las investigaciones sobre los problemas cognitivos de los esquizofrénicos, han tornado desde los años 60, a la neuropsicología, su método y sus instrumentos, siendo uno de sus principales objetivos el de localizar las zonas lesionadas del cerebro a partir de pertubaciones en los tests. Desde entonces, la neuropsicología ha evolucionado, gracias al hecho en particular del desarrollo de modelos que respon- den a los criterios de una neuropsicología cognitiva, orientados sobre la descripción de la organización de los problemas cognitivos, mas bien que sobre la localización de las lesiones cerebrales que las sostienen. Los instrumentos de evaluación utilizados corrientemente no corresponden, no obstante, a dichas evoluciones. En lo que concierne a los trabajos sobre los problemas cognitivos de los esquizofrénicos, solo una minoridad de entre ellos se han inspirado en la neuropsicología cognitiva. El desarrollo de la imaginacion cerebral parece aun haber alentado estos ultimos años, una cierta reviviscencia de la optica localizacionista. Por lo tanto, las conclusiones de las investigaciones orientadas según estos principios siguen imprecisas, tanto en aquello que concierne a la neuropatología, como en aquello también que concierne la naturaleza, la intensidad y la evolución de los problemas cognitivos. Esto resulta, al menos en parte, del uso poco adecuado de los instrumentos. Un análisis cualitativo de los modos de respuesta de los pacientes a los tests y la puesta en relación de sus resultados en los diferentes tests, permiten caracterizar mejor la naturaleza de los problemas cognitivos, cuyos mecanismos y arquitectura, a igual resultado, difieren en los esquizofrénicos y en los pacientes con lesiones cérébrales. Este análisis debe, de todas formas, tener un lugar en una teoría de funcionamiento mental, de la cual la teoría piagetiana puede constituir un modelo.

À propos de la question de la simulation dans l'hypocondrie : étude d'un cas
Authors: Rossel Frieda , Merceron Colette
Published: April 2023

Dans cet article, les auteurs discutent la différence établie par le DSM entre simulation et troubles factices et analysent un cas de suspicion de simulation sur la base des tests projectifs et d'épreuves de détérioration chez un sujet qui se plaint de troubles somatiques divers et de difficultés mnésiques. L'examen psychologique met en évidence une structure psychotique de nature paranoïaque.

Des troubles de la mentalisation aux atteintes narcissiques chez l'adolescent épileptique
Authors: Bobet René
Published: April 2023

L'épilepsie fut l'enjeu de débats passionnés entre organogenèse et psychogenèse des troubles psychiques des épileptiques. Le Rorschach reflète cette histoire d'une prévalence d'un mode de pensée médicale. D'où le désintérêt actuel pour une approche projective du vécu épileptique au profit d'une approche neuropsychologique. Pourtant envisagé comme une épreuve structurale et dynamique, le Rorschach peut contribuer utilement à la compréhension psychopathologique de l'épilepsie. Il met en évidence chez l'adolescent épileptique des troubles de la mentalisation, de l'investissement de l'Image du corps et du narcissisme. Des failles narcissiques plus accentuées se retrouvent chez certains adolescents dont l'épilepsie ancienne est résistante au traitement ; un fonctionnement « opératoire » apparaît d'un pronostic clinique plus favorable.

Published: April 2023

Marianne Dollander y Claude de Tychey, Asesinato de un niño y simbolización de la pérdida : aproximación clínica proyectiva longitudinal.

Los autores presentan los datos de un seguimiento longitudinal basado sobre el trabajo de duelo de una madre habiendo perdido a su hija en un asesinato. Ella ha beneficiado, durante un periodo de 16 meses, de un seguimiento psicoterapéutico asociado a un examen de la personalidad efectuado con la ayuda del Rorschach bajo la forma de un test-retest. Es posible, de esta forma, seguir la evoluciôn psicolôgica de esta mujer de la fase inicial de sideraciôn traumatica hasta la simbolizaciôn efectiva de la pérdida en continuaciôn del trabajo terapéutico. Algunas pistas de investigaciôn de alcance preventivo son también sugeridas.

La dialectique organisation/désorganisation comme recherche ou reflet d'un équilibre entre pulsions de vie et pulsions de mort
Authors: Golse Bernard
Published: April 2023

Après quelques rappels sur les notions de formation de la psyché, d'évolution et de structure, ce travail offre quelques exemples d'oscillation dialectique entre organisation et désorganisation choisis dans des champs différents (accordage affectif, positions kleiniennes, fusion et défusion, processus tertiaires). Après quoi, il envisage la question de la continuité et de la discontinuité au regard des nouveaux modèles du développement précoce de l'enfant, la continuité ne se situant peut-être pas du côté que l'on croit.

Design and Control for WLR-3P: A Hydraulic Wheel-Legged Robot
Authors: Li Xu , Yu Haoyang , Feng Haibo , Zhang Songyuan , Fu Yili
Published: April 2023

The robot used for disaster rescue or field exploration requires the ability of fast moving on flat road and adaptability on complex terrain. The hybrid wheel-legged robot (WLR-3P, prototype of the third-generation hydraulic wheel-legged robot) has the characteristics of fast and efficient mobility on flat surfaces and high environmental adaptability on rough terrains. In this paper, 3 design requirements are proposed to improve the mobility and environmental adaptability of the robot. To meet these 3 requirements, 2 design principles for each requirement are put forward. First, for light weight and low inertia with high stiffness, 3-dimensional printing technology and lightweight material are adopted. Second, the integrated hydraulically driven unit is used for high power density and fast response actuation. Third, the micro-hydraulic power unit achieves power autonomy, adopting the hoseless design to strengthen the reliability of the hydraulic system. What is more, the control system including hierarchical distributed electrical system and control strategy is presented. The mobility and adaptability of WLR-3P are demonstrated with a series of experiments. Finally, the robot can achieve a speed of 13.6 km/h and a jumping height of 0.2 m.

Authors: Groshenkova Victoria A. , Shabalina Svetlana A.
Published: April 2023

The article deals with the organization of preventive speech therapy work with young children in a preschool educational organization; the possibility of using productive activities in identifying and correcting speech disorders in young children is revealed; the results of a speech examination of children of the first junior group of three preschool educational institutions of the Tutaevsky municipal district (Yaroslavl region) in the amount of 70 people (32 boys, 38 girls) are described. The age of the studied children is from 1 year 9 months to 2 years 1 month. The study involved teachers (6 senior educators, 10 educators of groups for young children and 6 speech therapists) and 68 parents (legal representatives). The experimental work was built within the framework of preventive speech therapy work with young children based on the use of productive activities. The authors have developed a cycle of correctional and developmental classes in drawing and application in order to correct various aspects of the speech of young children, which meets the requirements of the educational program of a preschool educational organization, takes into account the level of psychoverbal development of children, involves the participation of educators, speech therapist and parents (legal representatives) on stages of diagnosis, correction and patronage. The authors use the term «speech-creative process», which involves the implementation of an interconnected speech and visual activity of the child, contributes to the prevention and / or correction of speech and motor disorders in children. The effectiveness of the experimental work is confirmed by the data of repeated diagnostics of the level of development of speech in young children. Conclusions are drawn about the need to conduct preventive speech therapy work in a preschool educational organization, to increase the staffing of speech therapists in a preschool educational institution, and to create advanced training programs for teaching staff working with young children. The tasks of implementing this area of work in the conditions of a preschool educational organization are outlined.
