Published: December 2021

The term “COVID” is breaking the hearts of the entire human community. The Corona virus is more infectious and is exceptionally irresistible, it is vital to isolate the patients and yet the specialists need to screen Corona virus patients as well. With the expanding increase in the number of Corona cases, the doctors find it difficult to keep track on the medical issue of isolated patients. To address this issue, we designed a distant IOT based screen framework, that considers observing of numerous Corona virus patients over the web. The system uses temperature sensor, respiratory sensor and pulse oximeter to measure the health parameters of the patients. If any oddity is detected in patient’s health, the patient presses the emergency help button which we installed in our system. This will alert the doctor and the care taker over IOT remotely. Our system thus provides a safe health monitoring design, in order to prevent the disease spreading through Corona virus and monitoring the individual health of each patient.

The use of online net banking official sites has been rapidly increased now a days. In online transaction attackers need only little information to steal the private information of bank users and can do any kind of fraudulent activities. One of the major drawbacks of commercial losses in online banking is fraud detected by credit card fraud detection system, which has a significant impact on clients. Fraudulent transactions will be discovered after the transaction is completed in the existing novel privacy models. As a result, in this paper, three level server systems are implemented to partition the intermediate gateway with better security. User details, transaction details and account details are considered as sensitive attributes and stored in separate database. And also data suppression scheme to replace the string and numerical characters into special symbols to overcome the traditional cryptography schemes is implemented. The Quasi-Identifiers are hidden by using Anonymization algorithm so that the transactions can be done efficiently.

Authors: Zhu Jing-E , Chen Yun-Chao , Yu Song-Yuan , Xu Hui-Xiong
Published: December 2021

Schwannoma is a benign tumor that originates from Schwann cells in the nerve sheathing of cranial, other peripheral, or autonomic nerves. Patients often present with painless mass as the chief complaint. The main symptoms of this tumor are related to its size and specific nerve origin. At present, the pretreatment diagnosis is mainly made by ultrasound, CT, MR, or biopsy, and the main treatment is surgical resection. We reported a new treatment method for cervical schwannoma in a 65-year-old woman with a history of non-small cell lung cancer (NSCLC). When the patient’s neck mass was initially found with hoarseness and severe cough, it was considered as cervical lymph node metastasis of lung cancer due to her medical history. And she was diagnosed with schwannoma by core-needle biopsy after chemotherapy failed and the tumor shrank after the radiotherapy with no improvement of the clinical symptoms. After considering the physical condition, the patients were treated in our department for minimal invasiveness treatment. The patient was definitively diagnosed with cervical vagus schwannoma and was treated with ultrasound-guided microwave ablation of schwannoma under general anesthesia with systematic evaluation and improved preoperative examination. Her condition was stable, and the symptoms of severe cough disappeared after anesthesia resuscitation and the ablation. The tumor continued to shrink after the operation with no recurrence of cough symptoms. Ultrasound-guided percutaneous microwave ablation (MWA) for cervical vagus schwannomas might be a minimally invasive, effective, and relatively safe alternative to conventional treatment for those patients with severe symptoms.

Published: December 2021

BACKGROUND: Recurrence or metastasis after surgery had been reported in hepatic epithelioid angiomylipoma (epi-AML). Most hepatic epi-AMLs were misdiagnosed with hepatocellular carcinoma or other hepatic tumors before surgery. OBJECTIVE: To describe the baseline and contrast-enhanced ultrasound (CEUS) features of hepatic epi-AMLs and to explore the potential ultrasonic features for prognosis. METHODS: The retrospective study enrolled 67 patients (56 females, 11 males) with 67 pathologically confirmed hepatic epi-AML lesions. All the lesions were examined by baseline ultrasound and 42 lesions were examined using CEUS with SonoVue (Bracco, Milan, Italy) before surgery. RESULTS: Baseline ultrasound features of hepatic epi-AMLs included heterogeneous echo (86.6%), well-defined border (68.7%), hypoecho (64.2%), regular morphology (62.7%), peripheral-tumor arc-shaped or ring-like vessels (53.7%), and low value of resistive index (0.51±0.08). CEUS features of hepatic epi-AMLs included arterial phase hyper-enhancement with smooth and well-defined margin (100%), peripheral-tumor ring-like vessels (57.1%), and intra-tumor vessels (52.4%). Some CEUS features, including arterial phase heterogeneously tortuous filling, intra-tumor vessels and peripheral-tumor ring-like vessels were more commonly found in hepatic epi-AMLs of uncertain malignant potential/malignant than in benign hepatic epi-AMLs (p < 0.05). CONCLUSIONS: Baseline ultrasound and CEUS features may be useful in diagnosis of hepatic epi-AML, and some CEUS features may be indicative of its malignant potential.

Published: December 2021

Background: Idiopathic normal pressure hydrocephalus (iNPH) is often misdiagnosed as Alzheimer’s disease (AD) due to overlapping pathophysiology and similar imaging characteristics, including ventricular enlargement and increased white matter lesions (WMLs). Objective: To compare the extent and distribution of WMLs directly between iNPH and AD and examine the association with underlying pathophysiology. Methods: Twelve patients with iNPH (mean age: 78.08 years; 5 females), 20 with AD (mean age: 75.40 years; 13 females), and 10 normal cognition (NC) participants (mean age: 76.60 years; 7 females) were recruited. The extent and distribution of WMLs and the lateral ventricular volume (LV-V) were evaluated on MRI using voxel-based morphometry analysis. Concentrations of cerebrospinal fluid biomarkers, such as amyloid-β protein (Aβ)42, Aβ40, Aβ38, and tau species, were also measured. Risk factors for small vessel disease (SVD) were assessed by blood examination and medical records. Results: The periventricular WML volume (PWML-V) and deep WML volume (DWML-V) were significantly larger in iNPH than in AD and NC. The DWML-V was dominant in iNPH, while the PWML-V was dominant in AD and NC. GM-V was significantly smaller in AD than in iNPH and NC. The LV-V positively correlated with WML-V in all participants. There was a significant negative correlation between LV-V and Aβ38 in iNPH. Furthermore, there was no significant difference in SVD risk factors between the groups. Conclusion: The differences in the extent and distribution of WMLs between iNPH and AD, especially predominance of DWML-V over PWML-V in iNPH, may reflect decreased fluid and Aβ clearance.
A test for fuzzy exponentiality based on Kullback-Leibler information
Authors: Kong Lingtao
Published: December 2021

The exponential distribution has been widely used in engineering, social and biological sciences. In this paper, we propose a new goodness-of-fit test for fuzzy exponentiality using α-pessimistic value. The test statistics is established based on Kullback-Leibler information. By using Monte Carlo method, we obtain the empirical critical points of the test statistic at four different significant levels. To evaluate the performance of the proposed test, we compare it with four commonly used tests through some simulations. Experimental studies show that the proposed test has higher power than other tests in most cases. In particular, for the uniform and linear failure rate alternatives, our method has the best performance. A real data example is investigated to show the application of our test.

Published: December 2021

Due to the increasingly demand of wireless broadband applications in modern society, the device-to-device (D2D) communication technique plays an important role for improving communication spectrum efficiency and quality of service (QoS). This study focuses on the optimal allocation of link resource in D2D communication systems using intelligent approaches, in order to obtain optimal energy efficiency of D2D-pair users (DP) and also ensure communication QoS. To be specific, the optimal resource allocation (ORA) model for ensuring the cooperation between DP and cellular users (CU) is established, and a novel coding strategy of ORA model is also proposed. Then, for efficiently optimizing the ORA model, a novel swarm-intelligence-based algorithm called the dynamic topology coevolving differential evolution (DTC-DE) is developed, and the efficiency of DTC-DE is also tested by a comprehensive set of benchmark functions. Finally, the DTC-DE algorithm is employed for optimizing the proposed ORA model, and some state-of-the-art algorithms are also employed for comparison. Result of case study shows that the DTC-DE outperforms its competitors significantly, and the optimal resource allocation can be obtained by DTC-DE with robust performance.

Published: December 2021

Background: The impact of SARS-CoV-2 infection among neuromuscular diseases with respiratory involvement, including amyotrophic lateral sclerosis (ALS), is still to be elucidated. Objectives: We aim to characterize the clinical outcome of ALS patients non-invasive ventilated (NIV), following SARS-CoV-2 infection. Methods: We analyzed retrospectively our patients followed regularly at our ALS clinic, from the beginning of the COVID-19 pandemic (middle March 2020) to March 2021. We included patients on NIV with a documented SARS-CoV-2 infection. We recorded demographic and clinical data, including from the acute infectious illness. Results: Three men with spinal-onset ALS are described, mean age of onset was 55±9.1 years (45–61), and mean disease duration was 17.5±15.9 months (6.1–41). All of them were wheelchair-bounded, with a mean ALSFRS-R of 15.3±0.6 (15–16). One patient used NIV 15 hours/day, 2 between 4 to 7 hours/day, and all used assisted coughing twice daily. None had coexistent comorbidities. They were managed for SARS-CoV-2 infection as outpatients with fluticasone, bronchodilators, azithromycin and increasing frequency of assisted coughing. Supplemental oxygen (mean of 2 liters per minute) was needed in two patients, and one required NIV also during the daytime. Total recovery from SARS-CoV-2 infection was observed in all, despite being in an advanced stage of their disease, with severe respiratory involvement. Conclusions: Prompt medical treatment is recommended for ALS patients with severe disease infected by SARS-CoV-2.

Published: December 2021

Background: Previous studies reported skin phosphorylated α-synuclein (p-syn) deposits in Parkinson’s disease (PD) patients but not in patients with parkinsonism due to tauopathies, although data on the latter are limited. Objective: We aimed to assess the presence of skin p-syn deposits in patients with clinical diagnosis of parkinsonism usually due to tauopathy and PD. Methods: We consecutively recruited 26 patients, 18 fulfilling clinical diagnostic criteria of progressive supranuclear palsy (PSP) and 8 of corticobasal syndrome (CBS), 26 patients with PD, and 26 healthy controls (HC). All subjects underwent skin biopsy to study p-syn deposits in skin nerves by immunofluorescence. Results: Skin p-syn deposits were present in only two of the PSP/CBS patients and none of the HC. Conversely, all PD patients showed p-syn deposition (p < 0.001, Chi-square). The two p-syn positive patients were diagnosed with PSP and CBS, respectively. Although clinical and MRI findings supported these diagnoses, both patients had some atypical features more typical of synucleinopathies. Conclusion: The detection of skin p-syn deposits may help in the differential diagnosis of parkinsonism. Indeed, in this study, all PD patients and only two out of 26 with a clinical diagnosis of PSP/CBS had skin p-syn deposits. Furthermore, these two patients showed clinical features that could suggest an atypical synucleinopathy presentation or a mixed pathology.

Published: December 2021

A Co3O4 enhanced La0.8Sr0.2Co0.5Fe0.5O3 - δ (LSCF) electrode is developed for use in air electrodes with proton conducting solid oxide fuel cell (SOFC). The incipient wetness impregnation method enables Co3O4 nanoparticles on the LSCF surface without altering the bulk porosity of the LSCF electrode. The polarization resistance of LSCF electrodes is significantly reduced by Co3O4 doping, and both charge transfer and diffusion/conversion resistances were positively affected. The highest reduction in charge transfer resistance is obtained at 700 °C, which is increased from 21 % to 32 % through reduction of po2. Conversely, the highest reduction in diffusion/conversion resistance is achieved at 550 °C. By increasing po2, the reduction is increased from 57 % to 66 % and its activation energy is reduced up to 33 % compared to pure LSCF. The lowest total area specific resistances obtained under air are 1.45 Ω·cm2, 2.95 Ω·cm2, 6.75 Ω·cm2 and 16.45 Ω·cm2 at 700 °C, 650 °C, 600 °C and 550 °C, respectively.

Published: December 2021

Periodontitis is an important health concern that is associated with long term complications. Development of resistance to antibiotics limits the treatment options in periodontitis. We investigated Thymus linearis essential oil for treatment of periodontitis. The essential oil was collected using hydrodistillation and characterized using GC-MS. The constituents were further analyzed for druglikeness, ADMET properties and molecular docking using transcription regulators 2UV0 and 3QP5. The GC-MS results revealed that carvacrol was a major constituent (76.26%) followed by caryophyllene oxide (6.83%) and L-borneol (6.08%). The in vitro antimicrobial studies showed significant inhibition against Staphylococcus aureus, Staphylococcus epidermidis and Pseudomonas aeruginosa (MIC range 0.024 –0.312μg/mL). The essential oil showed a good inhibition of bacterial biofilm produced by S. aureus (72%) and S. epidermidis (70%). Finally, the antiquorum sensing property (30 mm zone of inhibition) was recorded with violacein inhibition (58%). Based on in silico and in vitro findings, it was concluded that T. linearis essential oil can be used for the treatment of periodontal infections.
Performance Improvement in single-gate organic transistors with contacts at top and bottom: Additional p + region insertion near source and drain
Authors: Gupta Sakshi , Mittal Poornima , Juneja Pradeep
Published: December 2021

This research explores performance attributes of bottom gate top contact (BGTC) and bottom gate bottom contact (BGBC) organic thin film transistors (OTFT). To upgrade the performance characteristics, a region of 5nm with high concentration of carrier is tallied neighboring contacts. The drain current for BGTC is –18.6μA as compared to –5.1μA of BGBC transistor. Also, it is established that the innate attributes of BGTC are better than those of their counterparts, which is typically considered because of the inadequate contact attributes and mediocre semiconductor quality of BGBC OTFT. The analysis showed that upon varying the length of the channel ranging from 5μm to 40μm, there was a significant change in the drain current of BGTC and BGBC devices. For the same values of VGS and VDS (0V to –5V) where drain current in BGTC structure varied from –129.86μA to –13.69μA, whereas for their counterparts it ranged from –37.10μA to –3.76μA for channel length equal to 5μm and 40μm respectively. Also, with the varying doping strength ranging from 1012 cm–3 to 1016 cm–3 for BGBC device, drain current varied from –2.15μA to –18.52μA for BGTC whereas for BGBC it varied from –0.19μA to –7.09μA keeping VGS and VDS –5 V, yielding that upon varying the doping strength, where for BGTC ID changed by a factor of 8.6, the BGBC device showed a considerable change by a factor of 37.3. Likewise, mobility, threshold voltage, sub-threshold swing and transconductance also showing better performance with the P + insertion. These variations in the innate attributes are primarily due to the deficiency of carriers at the interface of source and channel, leading to a greater drop in the potential, which is more prominent for the bottom gate bottom contact devices.

Authors: Houben Milan , Chettouf Sabrina , Van Der Werf Ysbrand D. , Stins John
Published: December 2021

Background:

Unilateral neglect (UN) is a common and disabling disorder after stroke. UN is a strong and negative predictor of functional rehabilitative outcome. Non-invasive brain stimulation, such as theta-burst transcranial magnetic stimulation (TBS), is a promising rehabilitation technique for treating stroke-induced UN.

Objective:

To systematically review the available literature, researching whether TBS of the contra-lesional hemisphere is more effective than standard rehabilitation in improving symptoms of UN in patients with right hemisphere stroke.

Review methods:

A systematic review was conducted to retrieve randomized controlled trials (RCTs) that were relevant to the objective of this review. PubMed, Ovid and Cochrane Library electronic databases were comprehensively searched from inception up to February 2021. Of the included studies, methodological quality was assessed using the PEDro scale, whereafter a best evidence synthesis (BES) was conducted to summarize the results.

Results:

Nine RCTs investigating the effects of TBS on stroke-induced UN symptoms were included in this review. Seven studies assessing continuous TBS (cTBS) found significantly greater amelioration of UN symptoms in the TBS intervention group when compared to the control group; one study assessing cTBS found no such significant difference. One study assessing intermittent TBS (iTBS) found significant between-group differences in favor of the intervention. The BES yielded strong evidence in favor of cTBS, and limited evidence in favor of iTBS.

Conclusions:

The included studies in the present review allow the conclusion that TBS can have favorable effects on UN recovery in stroke patients. Its clinical use is recommended in conjunction with cognitive rehabilitation and occupational or physical rehabilitation as needed. However, many aspects for optimal usage of TBS therapy in clinical settings, such as exact TBS protocols, number of sessions, and treatment duration, are not clear.

Technological features of metal structures strengthening by gluing of high-strength FRP-systems during reconstruction
Authors: Rudnieva Iryna
Published: December 2021

The building heritage of Ukraine includes numerous examples of metal structures, especially used in industrial buildings and for large-span structures. The use of metal structures in construction is primarily due to their mechanical properties. They are frost-resistant and can withstand temperatures down to -65 degrees, tough, resistant, durable and reliable. They can also be used in areas with increased seismic activity. But, in certain situations metal structures need to restore or strengthen due to structural defects, wear of load-bearing elements, as well as in order to increase the bearing capacity. In some cases, strengthening with fiber-reinforced polymer composites (FRP) gives better results than traditional methods with metal strengthening.
A significant part of the Ukrainian architectural and historical heritage is made up of buildings and structures using metal structures. The first designs were made of cast iron or wrought iron (machined or tinned), but they subsequently developed rapidly along with the evolution of methods for forging mineral iron.
The main cultural reason for the restoration of old metal structures that guarantee structural functionality and load-bearing capacity, based not only on the need to preserve their historical origin, but also on the value of the landscape in which they are located.
Long-term operation of buildings and their structural elements made of metal without timely maintenance and major repairs, insufficient strength of structural materials, as well as changes in weather conditions and current regulatory documents in Ukraine, often leads to the need to recalculate the load-bearing metal structures of the building frame and strengthen them with the most effective methods, both from the point of view of reliability and from the point of view of profitability, which is influenced by prolonged shutdown of enterprises, stoppage of the production process or the inability to use the adjacent territory to carry out reconstruction work.
The article discusses the technological features of metal structures strengthening by gluing high-strength FRP-systems during the reconstruction of building, and also provides basic recommendations for the installation, monitoring and maintenance of strengthened elements.

The article is devoted to solving an urgent problem - the development of effective methods of water purification from heavy metal ions from industrial wastewater.
Today more emphasis on technologies that allow recycling of precious metals, the organization of return water supply and receipt safe disposal of sludge. Experimental studies of copper ions extraction from industrial wastewater of galvanic production by ferritization method have been carried out. The process of formation of ferromagnetic compounds of copper and iron has been studied. The results of X-ray diffraction analysis of the mineralogical composition of the samples and phase transformations that occur during aging and during the experiment are presented. The lattice constant of the α-ferite phase is calculated. X-ray diffraction analysis confirmed the presence of ferite compounds and metallic copper. In this case, in the process of "aging" of the samples, the amount of the ferrite phase and metallic copper increases. Electron microscopic analysis confirmed that in the surface layer changed due to the formation of new phases, copper-containing iron oxides, the formation of cement copper and cuprospinel simultaneously exist.
The influence on the course of the ferritization process of its conditions - the concentration and ratio of copper and iron ions, temperature, pH of the medium, the consumption of oxidant - oxygen is studied. The optimal parameters of the ferritization process for wastewater treatment from copper with an initial concentration of up to 10 g / l are determined. The possibility of formation of copper ferrite without aeration at a temperature of 200 C is shown.
The study of physicochemical properties of sediments formed during ferritization is performed.
Studies have shown that the residual concentration of copper in the solution after the application of the proposed technology is in the range from 0.14 to 0.6 mg / l. The efficiency of copper removal is 99.98%.
It is established that at the process temperature within 50… 700 C, the ratio
Cu: Fe = 1: 2.7, pH = 8.8… 10.5 and aeration intensity 4… 8 l / min precipitates are formed, which consist in the vast majority of ferrites and metallic copper.

La capacitación es el proceso que permite a la organización desarrollar la capacidad de aprendizaje de sus miembros, a través de la modificación de conocimientos, habilidades y actitudes, orientándola a la acción para enfrentar y resolver problemas del trabajo. En dos empresas del centro del país, uno del sector alimentos y otro del sector minero, desconocemos los beneficios de invertir en capacitación a los trabajadores. Por ello, utilizamos técnicas estadísticas, definiendo indicadores claves de desempeño (KPI) y diagnosticando la gestión actual de medición del impacto de la capacitación en cada organización. En algunos casos encontramos que es significativo el impacto de la capacitación en la productividad y en otros casos no es así.
Az online térben bekövetkező zaklatások lehetséges okai, dinamikai jellegzetességei és megoldási lehetőségei

A 21. században a technológiai újítások fénykorát éljük. Az online tér nagyban megkönnyíti mindennapjainkat, ugyanakkor számos előnye mellett a sötét oldalát is kénytelenek vagyunk megismerni. Nem kell a legdrasztikusabb cselekményekre gondolni ahhoz, hogy találkozzunk az internet veszélyeivel: elég csupán, ha zaklatásnak vagyunk kitéve a közösségi média egyes platformjain. Az online zaklatás, más néven cyberbullying olyan, agresszív és szándékosan ismétlődő cselekvés, amelyet egy egyén vagy csoport hajt végre elektronikus eszközök alkalmazásával (kép, videó eljuttatásával, telefonhívással, e-mailek küldésével, weboldalak és egyéb üzenetküldő programok használatával), s amellyel szemben az áldozat gyakran védtelen. Fontos feladat azonosítani az elkövetőket és feltárni az egyes zaklatások mögött meghúzódó dinamikai folyamatokat. Az elkövetők személyiségelemzése révén felkutatásuk és azonosításuk felgyorsulhat, az áldozatok jó esetben segítséget kapnak az átélt traumával való megküzdéshez és a reziliencia tudatos formálásával kapcsolatban, továbbá hatékony preventív és interventív módszerek kidolgozása is megvalósulhat.

Published: December 2021

O trabalho aborda a relação entre formação inicial e prática docente no ensino superior, enfatizando os saberes docentes mobilizados pelos professores e suas influências para a constituição de sua identidade profissional. Nesse artigo, questionamos quais saberes e práticas da formação inicial refletem na atividade profissional docente de professores de Educação Física do ensino superior? E como esses saberes e práticas contribuem para construção de sua identidade profissional?  Nesse sentido traçamos como objetivo analisar a relação entre a prática docente e a formação inicial de professores universitários, mapeando os principais saberes adquiridos durante o processo formativo dos sujeitos pesquisados e as contribuições desses saberes para a constituição de sua identidade profissional. Utilizamos de uma abordagem predominantemente qualitativa, partindo de um estudo de caso no âmbito do curso de Licenciatura em Educação Física de uma instituição pública de ensino superior do estado do Ceará, tendo como sujeitos da pesquisa, professores do referido curso. Como técnica de coleta de dados utilizamos a entrevista semiestruturada. A pesquisa nos revelou que os saberes da formação inicial se encontram refletidos nas atividades de ensino desenvolvidas pelos professores pesquisados, porém, não podemos considerá-los determinantes, tendo em vista, que os professores se encontram mobilizando outros saberes que não foram enfatizados em sua formação inicial. Contatamos ainda, a contribuição dessa etapa formativa inicial no processo de construção da identidade docente dos professores pesquisados, por meio de referências de ensino que marcaram de forma positiva (ou negativa) a formação desses sujeitos.

Na atualidade identificamos uma polêmica em torno do uso de medicamentos psicotrópicos em crianças cada vez menores, em virtude de supostos diagnósticos de Transtorno de Déficit de Atenção e Hiperatividade. Por meio de uma pesquisa de campo, realizada em três municípios paranaenses, na rede pública municipal de Ensino, nos segmentos de Educação Infantil e séries iniciais do Ensino Fundamental, foi possível verificar o percentual de crianças que fazem uso de medicamento controlado, qual o diagnóstico predominante e qual medicação mais prescrita. O diagnóstico predominante em ambos os segmentos foi o TDAH, na Educação Infantil o medicamento mais prescrito foi a Risperidona e no Ensino Fundamental foi a Ritalina. Problematiza-se os efeitos colaterais destes medicamentos e seu prejuízo para o desenvolvimento a partir das concepções da Psicologia Histórico-Cultural. Há uma correlação entre o aumento dos diagnósticos e das prescrições nas séries iniciais do Ensino Fundamental, que parece indicar a transformação das dificuldades inerentes à aquisição da linguagem escrita em supostos transtornos, que configura o quadro de medicalização da infância.
Pedagogia histórico-crítica e a educação escolar das pessoas com deficiência
Authors: Padilha Anna Maria Lunardi , Silva Régis Henrique dos Reis
Published: December 2021

O propósito deste texto é discutir a relação entre o movimento histórico, social e educacional da Educação Inclusiva no Brasil e a proposta da Pedagogia Histórico-Crítica como práxis pedagógica, no sentido da compreensão e da superação da exclusão escolar generalizada, ainda presente em nosso país. Para a Pedagogia Histórico-Crítica, a superação da sociedade de classes e das desigualdades por ela produzidas é uma condição fundamental para que a diversidade humana se realize de forma plena e radical. Partindo da realidade da educação Inclusiva no Brasil, seus impasses e suas conquistas, o texto aborda os desafios e possibilidades da formação humana com escola para todos, em salas de aula que devem, efetivamente, atender às singularidades de seus alunos em direção ao domínio dos conhecimentos que a humanidade desenvolveu e a ciência, a filosofia e as artes sistematizaram. Em seguida, reflete-se, com os fundamentos da Psicologia Histórico-Cultural, que uma teoria pedagógica revolucionária deve mediar, por meio da obra da cultura, o desenvolvimento mental dos indivíduos, promovendo saltos de qualidade no desenvolvimento humano. O texto finaliza apontando a contraposição ao que propõe os “Projetos de Escolas sem Partido” que procuram restringir e eliminar o debate de ideias e as possibilidades do pensamento plural. Insiste-se na necessidade do estabelecimento de condições para que as “muitas vozes” sociais manifestem e apresentem suas explicações para os problemas concretos que afligem as pessoas com deficiência e as demais minorias sociais.
