Authors: Yıldız Çoksan Serpil , Bütün Ayhan Aynur , Karabulut Şahin
Published: June 2024

This study aimed to understand and explore the experiences of deaf parents who have hearing parents by examining in depth their experiences while raising their hearing children. To do this, we conducted in-depth interviews with four deaf parents (four mothers and four fathers) using Turkish Sign Language. Interpretative phenomenological analysis revealed four main themes: (a) concern about the child, (b) need for social support, (c) communication, and (d) access to information sources. All these themes indicated that deaf parents in Türkiye have difficulty communicating in hearing society, have problems receiving public services through sign language, and experience prenatal and postnatal anxiety about their children because they have difficulty accessing suitable sources of information. We discussed the findings in the context of Türkiye's policies towards the Deaf community and the types of intervention Programs that may be suitable to be implemented in the future.

IMPLEMENTATION OF LEARNING MANAGEMENT SYSTEM (LMS) IN PNS COMPETENCY DEVELOPMENT ACTIVITIES IN BPSDM GORONTALO PROVINCE
Authors: Laraga Riwan
Published: June 2024

Digital transformation in the bureaucratic environment is not something new, but it appears that it has not been implemented evenly and quickly, both in its implementation and in adapting to technology transfer by the bureaucracy and service users. Digital-based bureaucratic implementation is still dominant in financial matters. The end of 2019 was a momentum to accelerate the digital transformation of the bureaucracy, because the bureaucracy was faced with a situation where it was inevitable that they had to use digital services to avoid physical connections considering the corona virus or Covid-19 outbreak. No exception, civil servant competency development activities through training must be carried out with a new concept, namely digitally. Learning Management System (LMS) in training activities as a solution so that competency development can still be implemented. Of course, this must be adapted according to the demands of needs while still considering effectiveness and efficiency. The manifestation of the accelerated transformation of competency development through digital learning can be seen from various LMS implementation policies by the State Administration Institute of the Republic of Indonesia (LAN RI) as the supervisory agency. This scientific paper will analyze the application of LMS in the implementation of competency development through training attended by civil servants. Apart from that, it will also explain how it is implemented by elements of training organizers and managers as well as widyaiswara as facilitators to training participants. The approach in this research is descriptive qualitative which will interpret the phenomena found at the BPSDM research location in Gorontalo Province. Sampling was carried out by purposive sampling of Widyaiswara, Latsar participants, PKA participants, PKP participants, training managers and training organizers. A literature study was carried out to understand the concept of implementing an LMS based on existing regulations and to interpret studies in the literature related to digital transformation, especially LMS. The research results illustrate that LMS is very useful for developing employee competency, but its use is still deemed to be less effective due to the limitations of training participants, training organizers and managers as well as Widyaiswara in exploring the use of the LMS provided by LAN RI.

Published: June 2024

El cultivo de plátano es fundamental para las familias colombianas que buscan competir en el mercado de manera ecológica. Este estudio se enfocó en medir la altura y calcular el diámetro de las plantas de plátano, utilizando métodos de fertilización orgánica que respeten el ambiente. La investigación se llevó a cabo en la finca Alto Peñasora, ubicada en Puerto Asís, Putumayo, Colombia. Se establecieron cuatro tratamientos, aplicando residuos de frutas y verduras, estiércol bovino fresco y gallinaza con una relación carbono/nitrógeno de 3-1. Los tratamientos fueron: T1- testigo, T2 - abono verde, T3 - 6 kg de abono orgánico y T4 - 4 kg de abono orgánico. Se evaluaron las variables de altura y diámetro de las plantas. Los resultados mostraron que, aunque el diámetro de las plantas no presentó diferencias significativas debido a las limitaciones de crecimiento impuestas por el clima estival, la altura sí varió significativamente. El tratamiento testigo alcanzó la menor altura, lo cual indica que el abono orgánico fue efectivo en mejorar este parámetro. Este hallazgo sugiere que la fertilización con abono orgánico no solo es viable sino también beneficiosa para el crecimiento de las plantas de plátano en las condiciones específicas de la llanura amazónica del departamento de Putumayo, ofreciendo una alternativa ecológica para la agricultura local.

Published: June 2024

A formação docente reverbera ações estratégicas que empoderam os professores para desempenharem seu trabalho com mais segurança e qualidade. O coordenador pedagógico desempenha um papel fundamental na formação continuada e também precisa de aporte pedagógico. A formação perpassa por processos que afetam os coordenadores, para que, através da homologia de processos, afetem sua equipe docente. Esse relato apresenta um momento de formação de coordenadores pedagógicos de uma grande rede de ensino, cujo principal objetivo era proporcionar momento de construção coletiva de um plano de ação baseado no Planejamento Reverso. Esse momento buscou incentivar reflexão sobre obstáculos que dificultam ou inviabilizam o processo qualificado de ensino e aprendizagem; estimular perfil pesquisador com a abordagem da sala de aula invertida e oportunizar momento de reflexão sobre gestão de aprendizagem. A contribuição para a prática pedagógica reside no fato da importância do planejamento, que visa a contemplação dos objetivos propostos com foco na personalização da prática, considerando as diversidades dentro de uma sala de aula e possíveis barreiras para que se alcance o resultado esperado. Um plano de ação foi construído mediante as etapas delineadas e as propostas socializadas para que coletivamente fosse possibilitada a reflexão sobre a aplicação prática do plano em alguma das unidades escolares nas quais os coordenadores atuam. Com o planejamento reverso a seleção de prioridades ficou evidente e a partir desse momento é elucidada uma clareza na definição de metas que são mais condizentes com as reais necessidades, tendo em vista que não se inicia pelos conteúdos, mas sim na correlação entre conteúdos, habilidades, competências, valores e atitudes.

Authors: Vicente Valdir Natalino , Grani Gabriel
Published: June 2024

O presente estudo evidencia a importância da Hierarquia e da Disciplina para a organização da vida em sociedade, fazendo uma análise de sua evolução e definição para a sociedade civil e militar. Enfatiza-se que para as instituições militares, a hierarquia e a disciplina são fundamentais, uma vez que suas estruturas são baseadas nestes institutos, os quais possibilitam o funcionamento eficiente daquelas, bem como um controle rígido de seus recursos humanos. Neste sentido, o presente estudo esclarece que a atualização da Diretriz nº 005 de 2011 da Polícia Militar do Estado do Paraná, lavrada em 2021, ao tratar de seus elementos essenciais, retirou do Gerente da Crise (oficial mais antigo) o Poder de Decisão e o repassou ao Comandante do Teatro de Operações, gerando então um flagrante conflito, no qual o oficial mais antigo presente não possui gestão sobre a decisão crucial para desfecho do evento crítico. Por fim, este Artigo aponta que, sobre o enfoque da hierarquia e da disciplina, tal distorção deve ser corrigida a fim de manter hígidos, fortes, esclarecidos e dignos os preceitos basilares das instituições militares estatuídas por estes institutos.

El fosfito (Phi) es un bioestimulante que está recibiendo un interés creciente en la horticultura debido a que su aplicación en cultivos ha mejorado el rendimiento, calidad y la tolerancia a diversos tipos de estrés. Se evaluaron cuatro dosis crecientes de fosfito (0, 0.1, 0.3 y 0.5 mM) durante 30 días en condiciones in vitro en caña de azúcar (Saccharum spp.) durante la etapa de multiplicación. Se utilizaron las variedades CP 72-2086 y Mex 69-290 en las que se registraron variables de crecimiento (brotes, hojas y biomasa) y bioquímicas (clorofilas, carbohidratos, aminoácidos y proteínas). Para el análisis de datos se realizó análisis de varianza y se aplicó la prueba de Tukey (P ≤ 0.05) para la separación de las medias. La dosis de 0.3 mM Phi en la variedad CP 72-2086 incrementó la longitud, ancho y número de hojas; también incrementó el número de brotes y la concentración foliar de clorofilas a y b. El tratamiento con 0.3 mM Phi en la variedad Mex 69-290 aumentó el tamaño de brotes y longitud de hojas. Por lo tanto, el Phi tiene un papel crucial como bioestimulante inorgánico en variedades de caña de azúcar cultivadas in vitro, al mejorar las variables de crecimiento y bioquímicas.

El girasol (Helianthus annuus) es originario del centro y norte de México, Estados Unidos y el sur de Canadá; sin embargo, la industria aceitera mexicana importa de Argentina, Estados Unidos y Canadá el 95 % del grano. El mercado demanda aceite tipo alto oleico por sus beneficios a la salud y estabilidad durante el freído, por lo que las empresas impulsan agricultura por contrato para su siembra a productores interesados; sin embargo, dado que no se han generado variedades alto oleicas mexicanas, el agricultor debe asumir un alto costo por el uso de semilla híbrida de empresas transnacionales. Por lo anterior, en el presente estudio se planteó como objetivo desarrollar variedades alto oleicas mediante la aplicación de marcadores moleculares asociados con la mutación de Pervenets que origina el genotipo Ol y el fenotipo alto oleico; para ello se aplicó el método de mejoramiento denominado selección recurrente entre progenies autofecundadas (SREPA). Con esta metodología se obtuvieron 54 líneas alto oleicas S4 y variedades sintéticas de ciclo precoz, intermedio y tardío, las que se evaluaron en cuatro municipios y cinco ambientes. Los resultados mostraron rendimiento de hasta 3.4 t ha-1 y porcentaje de aceite oleico entre 90.1 y 93.1 %, comparables con los mejores híbridos comerciales alto oleicos usados como testigos.

Published: June 2024

El pasto banderita [Bouteloua curtipendula (Michx.) Torr.] cuenta con gran variabilidad morfológica y genética en los pastizales del norte de México, lo cual sugiere que existe la posibilidad de selección de genotipos resistentes a condiciones de zonas áridas; sin embargo, la información sobre su eficiencia fotosintética y características estomáticas es escasa. El objetivo del presente estudio fue relacionar la eficiencia fotosintética, características estomáticas y producción forrajera en poblaciones de pasto banderita. Se utilizó un diseño de bloques completos al azar con cuatro repeticiones. Se establecieron 216 macetas en invernadero donde se evaluaron como tratamientos 51 poblaciones de pasto banderita del estado de Chihuahua, México y tres variedades comerciales como testigos. Se evalúo la eficiencia fotosintética y las propiedades estomáticas; además, se cuantificó la acumulación de forraje. Se realizaron análisis estadísticos descriptivos, análisis de correlación, componentes principales, análisis de agrupamiento y análisis multivariado de la varianza. Las medias para disipación de calor no regulada (YNO, 0.223) y disipación de calor regulada (YNPQ, 0.447) indicaron que estas variables son proporcionales a la eficiencia fotoquímica del fotosistema II (YII, 0.330). Los valores máximos y mínimos en producción de forraje fueron 9.8 y 17.92 g por planta y altura de planta de 7.3 y 23 cm, respectivamente. Existe correlación positiva entre área estomática (AE) y disipación de calor regulada con altura de planta y producción de forraje. En el análisis de componentes principales los dos primeros explicaron el 58.8 % de la variación total. Se encontraron 11 poblaciones sobresalientes en disipación de la energía regulada controlando la fotoinhibición, sin poner en riesgo la producción de la planta.

Se evaluó la efectividad del colágeno extraído de la escama del pez Tilapia del Nilo (Oreochromis niloticus) en la encapsulación de β-caroteno. Se realizaron dos encapsulaciones por liofilización: encapsulación con proteína de soya (EP) y encapsulación con colágeno y proteína de soya (EPC) en proporción 1:4. Las muestras se caracterizaron fisicoquímicamente, se evaluaron sus propiedades de fluidez y se utilizaron modelos matemáticos y cinéticos para predecir la estabilidad del β-caroteno encapsulado almacenado a 35 °C durante ocho semanas. Se obtuvo un rendimiento de extracción de colágeno del 13.85 %, el colágeno tuvo la siguiente composición proximal: proteína 47 %, ceniza 40 %, grasa 9 % y humedad 7.9 %. Inicialmente, EPC mostró una mayor tasa de retención (TR = 83.4 %) que EP (TR = 53.3 %), mientras que después del almacenamiento a 35 °C durante ocho semanas, la retención de β-caroteno en EPC fue de 0.84 %, mientras que en EP alcanzó solo 0.48 %. La eficiencia de encapsulación de EPC (66.7 %) fue mejor que la de EP (42.6 %). Se encontró alta cohesividad y fluidez intermedia en EP y cohesividad intermedia y fluidez intermedia en EPC. Según los resultados, el colágeno de esta fuente demostró ser un material funcional para encapsular el β-caroteno.

Published: June 2024

Las poblaciones de Pinus montezumae del centro de México son esenciales por su contribución en servicios ambientales a más de 25 millones de personas de esta zona. Estos bosques han sido amenazados por el cambio de uso de suelo y la fragmentación, lo que reduce su regeneración. El objetivo del presente estudio fue determinar la germinación de semillas y algunas características morfológicas de plántulas de P. montezumae de ocho poblaciones del centro de México, así como analizar la influencia de la densidad de rodales y variables climáticas y edáficas sobre la calidad de semillas. Se utilizaron semillas de 10 árboles por población. Se evaluaron varios parámetros germinativos y características morfológicas de plántulas a los 40 días después de emergencia. Se utilizó un modelo lineal mixto generalizado para evaluar la significancia del factor población en cada característica y se realizaron análisis de correlación de Pearson con variables edáficas, ambientales y de densidad. Hubo diferencias estadísticas (P ≤ 0.05) en las variables evaluadas. La germinación media fue 84 %, con variación de 80.7 a 87 % entre poblaciones. Las plántulas presentaron, en promedio, 6.5 cotiledones (3-10, pero 6-7 más común) con una longitud de 29 mm y un hipocótilo de 16.4 mm. La germinación estuvo relacionada con la precipitación (r = 0.75), y el número y la longitud de cotiledones con la temperatura de los sitios de origen de las poblaciones (r = 0.84, r = 0.87, respectivamente). La materia orgánica mostró correlación negativa con la longitud de cotiledones (r = -0.94). El contenido de fósforo del suelo de origen correlacionó positivamente con la germinación (r = 0.94) y con el número de cotiledones (r = 0.77), mientras que el nitrato lo hizo con la longitud del hipocótilo (r = 0.80). La densidad de árboles no presentó correlación con las variables evaluadas, por lo que el bajo número de árboles no es limitante para la repoblación.

Published: June 2024

Animal carcasses in natural environments are a food source for various organisms, such as fungi, bacteria, and insects. Insects also utilize this ephemeral resource for oviposition and development of their offspring, with the immatures being responsible for the greatest consumption of the resource. Thus, the aim of this study was to characterize the fauna of necrophagous insects associated with a cow carcass Bos taurus Linnaeus found in the municipality of São Raimundo das Mangabeiras, Maranhão, Brazil. Insects were sampled using forceps and entomological nets for eight days, with the immatures being taken to the Laboratory of Entomology and Vectors (LEV) and subsequently reared at room temperature. A total of 1,149 specimens were sampled, comprising 141 adults and 1,017 immatures. Among the adults, the species Chrysomya albiceps (Widemann), Necrobia rufipes (Fabricius), and Dermestes maculatus (De Geer) were prominent. Regarding immatures, all insects that emerged were of the species C. albiceps. Additionally, we report the first record of Chrysomya putoria (Widemann), Cochliomyia hominivorax (Coquerel), and Hemertia illucens (Linnaeus) visiting bovine carcasses in the Neotropical region. The results reveal a late colonization of C. albiceps in advanced stages, confirming the importance of research with carcasses in the context of forensic entomology.

La contabilización de huevos de mosquitos en campo requiere de tiempo y personal operativo con experiencia, y en algunos casos, la ayuda de costosos equipos de laboratorio. Además, se pueden presentar errores humanos al realizar este tipo de conteos manual y visual, por lo que se han desarrollado algoritmos para el conteo automático. Debido a que algunos algoritmos o interfaces llegan a necesitar de un conocimiento matemático elevado o de recursos informáticos con hardware complejos, el presente trabajo presenta un software (JAVA) sin costo, con interfaz amigable y accesible a equipos de cómputo básicos y sin la ayuda de conexión a internet, para el conteo automático de huevos de mosquitos. El software desarrollado se puso a prueba usando papeletas de ovitrampas con huevos de Aedes aegypti que fueron digitalizadas y analizadas mediante el software JAVA denominado “CERECOVE”. El software requirió de aproximadamente cinco minutos para la cuantificación en una amplia gama de números de huevos, siendo un software fácil de operar, gratuito y una opción útil para este propósito. Únicamente los valores de la comparación de la categoría “muy abundante” entre conteo manual y el programa JAVA-CERECOVE presentaron diferencias estadísticamente significativas (P= 0,01491). Este software puede representar una herramienta poderosa para aumentar la vigilancia de enfermedades transmitidas por vectores y evaluar el impacto de los programas de control.

Published: June 2024

In this paper we propose an approach for chaotic time
series and extreme events prediction based on WaveNet model, which is a deep neural network that directly synthesizes speech waveforms from acoustic features. We test our approach on artificial data obtained from long time series with extreme events generated by two coupled bursting Hindmarsh-Rose neurons, and on two real-life data sets (local field potentials recorded in mice and electroencephalogram recorded in humans) containing patterns of epileptiform activity, which also can be viewed as extreme events.
Masked autoencoder-based self-supervised learning for forest plant classification
Authors: Huy Luu Van , Tuong Nguyen Huy , Han Le Hoang Ngoc , Hieu Nguyen Van
Published: June 2024

Forest plant identification and classification play a pivotal role in various domains, encompassing biodiversity conservation, agricultural advancement, and beyond. Conventional plant identification methods often rely on expert botanists or manual identification approaches, which can be time-consuming and subjective. Deep learning models have emerged as a promising approach to automatically classify plants, offering high accuracy and efficiency. However, these models often rely on convolutional neural networks (CNNs) and their variants to extract features, which may fail to capture the complex relationships among plant characteristics. This paper proposes a novel feature extraction method using semi-supervised learning techniques combined with Masked Autoencoder architecture to enhance the feature extraction of plant data, applicable to problems with limited datasets. The proposed model, named MAE SGD, achieves an accuracy of nearly 94% on the QuangNamForestPlant - a dataset collected by our research team in Quang Nam province, Central Vietnam, comprising
24,314 images of 710 different forest plant species. Future research directions will focus on expanding the forest plant dataset and improving the recognition model to increase the model’s accuracy and overall performance in identifying forest vegetation.
Robust control of one class of nonlinear systems with a distributed delay
Authors: Imangazieva Aliya
Published: June 2024

The paper presents a novel robust control of one class of nonlinear single-input single-output (SISO) systems with distributed delay on state used the auxiliary loop method. The problem is solved by introducing an auxiliary loop and using two Khalil observers to compensate for a generalized disturbance signal containing information not only about the parametric uncertainty of the installation model, but also information about distributed delay and disturbances. The designed control law is investigated in MATLAB. To illustrate the obtained results, an example of a nonlinear system with a distributed time delay is given. It is shown that the proposed control law under conditions of parametric uncertainty ensures the achievement of the goal with a given accuracy.

Algorithms for guidance and control of a space robot-manipulator when approaching mini-satellites in adjacent orbital planes of the earth-survey constellation and the results of their computer verification are presented. The article examines the issues on astrodynamics of a space robot in the gravitational fields of the Earth, Moon and Sun, taking into account the aerodynamic resistance to its movement in low orbit. At the same time, an electro-reactive propulsion unit and a cluster of gyroscopic drives are used to create vectors of control forces and torques. The most important are new methods and results for the space robot digital control during its flight between mini-satellites.
Space, time and life in quantum-semiotic view
Authors: Surov Ilya
Published: June 2024

The origin of space and time is the deepest question in fundamental physics. This paper addresses it from quantum-theoretic perspective, deriving both concepts from elementary principles. Time appears as a measure for the stream of decision acts, collapsing quantum potentialities of the future to actual reality. Guiding of this construction is identified as fundamental function of life, thus obtaining definition in cybernetic style. This entails specific geometric structure of subjective meaning identical to that of the simplest quantum state, the qubit. Alignment of individual meaning spaces then produces 3-dimensional Euclidean space as biologically fixed format of common sense. The problem of space-time is thereby triangulated with the nature of life, identifying these three concepts as integral sides of the same fundamental phenomenon. The theory opens new prospects for scientific and ethical progress.

The objective of this study is to determine the factors that inﬂuence the adoption and use of e-learning platforms by older people in Chile, based on the Uniﬁed Theory of Acceptance and Use of Technology 2 (UTAUT-2) and the theory of Personal Innovativeness in Information Technology (PIIT). Data were collected from 138 elder people from various communes in the province of Concepción, Chile, through a survey. For the analysis of the data and validation of the hypotheses, a structural equation model was used. The results indicate that effort expectancy, social inﬂuence, hedonic motivation, and facilitating conditions signiﬁcantly inﬂuence the intention to use e-learning platforms by these people. In addition, it was found that facilitating conditions and the intention to use are positively related to the use of e-learning platforms. The results indicate the importance of considering the innovative characteristics of the elderly in all the variables that precede the intention to use e-learning platforms. It is relevant to consider that this age group be part of the social and technological development that society is experiencing. In this way, they would improve their quality of life, remain active and independent for longer time.

Published: June 2024

Las prácticas Lean se consideran en la literatura como una ﬁlosofía de trabajo que les permite a las organizaciones identiﬁcar y eliminar aquellas acti-vidades que no generan valor, a menudo llamadas residuos, las cuales tienen un impacto no solo en los procesos productivos, sino también en la cadena de suministro, en las actividades de logística y en el nivel del rendimiento empresarial. Sin embargo, son relativamente pocos los estudios publicados en la literatura que han analizado y discutido la relación y consecuencias de la aplicación de las prácticas Lean y sus efectos en la cadena de suministro Lean y el rendimiento empresarial. Por ello, el objetivo esen-cial de este estudio es llenar el vacío que existe en la actual literatura y probar empíricamente la aso-ciación positiva entre las prácticas Lean, la cadena de suministro Lean y el rendimiento empresarial. Para este propósito, se distribuyó una encuesta a una muestra de 460 empresas manufactureras de la industria automotriz de México, y se validó el modelo de investigación propuesto por medio del uso del PLS-SEM. Los resultados sugieren que las prácticas Lean tienen un impacto positivo tanto en el rendimiento empresarial como en el de la cadena de suministro Lean, al igual que la cadena de sumi-nistro Lean también tiene un efecto positivo en el rendimiento empresarial.

Objective: to evaluate the long-term results of mastoidoplasty with bone chips in patients with chronic suppurative otitis media. Materials and methods: Surgical treatment of 38 patients with chronic suppurative otitis media and sclerotic type of mastoid structure was performed. Anatomical and functional results were assessed according to otoscopy, audiometry, CT of the temporal bones. Results: a satisfactory anatomical result was obtained in 84% (32 patients), unsatisfactory in 16% (6 patients), among them 1 recurrence of cholesteatoma, 3 cases of partial lysis of the osteoplastic material with the formation of retraction pockets, 2 cases of formation of partial fibrous atresia of the external auditory passage. According to audiometry after 1 year, in 16 patients (42%) the air-bone interval was at the level of 0–10 dB, in 14 (36%) patients it was 10–20 dB, in 4 (11%) patients it was 20–30 dB, more than 30 dB in 4 patients (11%). The mean value of the air-bone interval before surgery was 26.7 ± 10.9 dB, after surgery 20.8 ± 10.8 dB (P < 0.05). Conclusion: the technique of mastoidoplasty using bone chips during primary operations in patients with chronic suppurative otitis media with cholesteatoma and sclerotic structure of the mastoid process, showed high efficiency and allows achieving satisfactory anatomical and functional results in 84%.
ANALYSIS OF THE UNSUCCESSFUL OUTCOME OF OSSICULOPLASTY DUE TO THE PECULIARITIES OF PROSTHESIS FIXATION

Published: June 2024

The reasons for unsuccessful functional outcomes of ossiculoplasty are poor aeration of the middle ear, cicatricial deformity, adhesive process in the tympanic cavity, incorrectly selected length of the prosthesis, which ultimately leads to dislocation or extrusion of the implant with deformation of the neotympanic membrane in 1-6% of cases. The article presents a clinical case of dislocation of a partial prosthesis after ossiculoplasty with tympanoplasty, the cause of dislocation of which is not a widespread one. Patient K., 42 years old, previously underwent tympanoplasty with ossiculoplasty with a partial prosthesis for left-sided mesotympanitis with destruction of the ossicular chain. Despite the improvement in hearing in the early postoperative period, the patient began to notice a gradual decrease in hearing in 6 months. The examination revealed left-sided conductive hearing loss of the 3rd degree with a air-bone gap (ABG) of 40 dB, cicatricial deformity of the anterior meatotympanic angle, according to computed tomography of the temporal bones (CT), lateralization of the neotympanic membrane with cicatricial deformity of the anterior meatotympanic angle, diastasis between the head of the stapes and leg of a partial prosthesis. The head plate of the prosthesis is adjacent to the inner surface of the neotympanic membrane together with the cartilaginous plate. During an intraoperative detailed examination of the extracted prosthesis, it was revealed that the head plate of the prosthesis was fixed to the cartilage with three interrupted sutures with a thread of non-absorbable material, the nodes were located on the side of the prosthesis stem. A repeated ossucoloplasty was performed with a longer partial prosthesis, eliminating atresia in the anterior meatotympanic angle. ABG was less than 10 dB, on the control CT of the temporal bones, the tympanic cavity was airy, the partial denture was in the correct position in 10 months. This clinical case is of particular interest, since the unsuccessful outcome of tympanoplasty with ossiculoplasty was due to the peculiarities of fixing the denture plate with suture material combined with the peculiarities of the reparative process.
