Nuevas notas a “La niña de plata”: calificativo de Dorotea
Authors: Ferreira Barrocal Jorge
Published: December 2022

El apelativo de Dorotea -protagonista de la comedia urbana La niña de plata- solo ha sido estudiado por Muriel (2007) en el prólogo de su edición. A partir de las referencias aparecidas en un ciclo poético valenciano de finales del siglo XVI, la editora concluye que “la niña de plata” es la duquesa Isabel de Híjar. Sin embargo, ningún elemento textual de la comedia permite sostener tal conjetura. En verdad, la selección del epíteto responde a razones de orden económico. Se llega a esta conclusión después de haber llevado a cabo una lectura atenta de una serie de pasajes de la obra a la luz del contexto metalífero y monetario de la temprana modernidad hispánica, algo que nunca antes se había contemplado en las aproximaciones anteriores a la pieza del Fénix.
Fratricidio y rebelión en los dramas del Sturm und Drang: Leisewitz, Klinger y los hermanos enfrentados
Authors: Carmen-Cerdán Rodrigo
Published: December 2022

El presente artículo se propone analizar las obras Julius von Tarent de Johann Anton Leisewitz y Die Zwilinge de Friedrich Maximilian Klinger, ambos publicados en 1776 y exponentes del drama del Sturm und Drang. En estos análisis se estudiarán las motivaciones de los personajes, así como las reinterpretaciones que cada obra ofrece del fratricidio de Caín y Abel: en Leisewitz, Julius no puede unir las esferas de la razón de Estado y del amor, con lo que decide rebelarse contra la primera e intentar huir, pero Guido se lo impide y termina asesinándolo; en Klinger, Guelfo cuestiona la primogenitura de Ferdinando y la reclama para sí, pues considera que se la han robado y le han dado todo a su hermano. Mediante las acciones de los personajes de ambos dramas se hace visible la maquinaria de subordinación y ejercicio del poder que opera en ellos. Se concluye que las obras no deben verse como dramas revolucionarios, sino que más bien en ellos opera una incipiente crítica a los postulados ilustrados y se muestra la decadencia e inminente colapso de una sociedad/familia demasiado rígida e hipócrita que busca únicamente su preservación y continuidad sin tener en cuenta las consecuencias internas, esto es, la fragmentación y polarización que puedan provocar.
Intención de abandono y resiliencia en estudiantes universitarios de nuevo ingreso
Authors: Blanco Elena , Galve-González Celia , Herrero Francisco Javier , Bernardo Ana B.
Published: December 2022

El abandono universitario es un fenómeno global y complejo, que se produce como resultado de la interacción de múltiples variables académicas, económicas, afectivo-motivacionales, etc. Entre éstas, la resiliencia puede resultar importante porque la transición del bachillerato a la universidad supone un gran cambio en la vida de los estudiantes, donde la capacidad de adaptación al nuevo entorno es fundamental. La presente investigación busca analizar la relación que existe entre la capacidad de resiliencia de los alumnos y la intención de abandono universitario. Además, busca comparar los niveles de resiliencia y la intención de abandono entre las titulaciones analizadas. Se contó para ello con una muestra de 440 estudiantes de nuevo ingreso del Grado en Magisterio y del Grado en Psicología, de diferentes universidades españolas, y se implementó un cuestionario ad hoc para medir la intención de abandono y una escala de resiliencia. Los resultados indican que los alumnos que muestran intención de abandono poseen puntuaciones más bajas en la escala de resiliencia. Además, muestran que los estudiantes del Grado en Psicología tienen una mayor intención de abandono que los estudiantes del Grado en Magisterio. Por ello, se sugiere la implementación de herramientas que fomenten la resiliencia como medida preventiva del abandono universitario.

Authors: Hevia Artime Isabel , Montes García María
Published: December 2022

El objetivo de este trabajo es presentar un estudio centrado en conocer la forma en que niños y niñas de sexto curso de Educación Primaria de cuatro centros educativos asturianos representan el proceso migratorio a través de sus narraciones. Para ello, en 2017 se plantea una investigación de tipo exploratorio que posibilita el acceso a la subjetividad de los menores a través de una técnica cualitativa de carácter proyectivo consistente en una narrativa inconclusa. En general, en los relatos de los niños y niñas se evidencia una representación social de las migraciones un tanto idealizada en donde se pone de manifiesto la influencia de las informaciones procedentes del medio social y se detectan diferencias entre quienes han vivenciado un proceso migratorio y quiénes no.
Una escuela para todos y todas. La herencia educativa de la Segunda República Española
Authors: Parra-Nieto Gabriel , Del Castillo Encinar Borja
Published: December 2022

El impulso transformador de la Segunda República partía desde la base de que la igualdad de la ciudadanía y la educación eran necesarias para construir una sociedad más justa. Así, las ideas del regeneracionismo, el institucionismo y el socialismo permearon el nuevo sistema educativo. Para conocer el impacto de estas medidas, se ha recogido la valoración que hacen de las aportaciones educativas republicanas y de su estado actual de desarrollo 40 profesionales de la educación, mediante una encuesta que combina preguntas tipo Likert y de respuesta abierta. En ellas se destaca que los ámbitos en los que más intervino la República fueron: la extensión del sistema educativo, la coeducación y las misiones pedagógicas, mientras que la que más desarrollo ha alcanzado en la actualidad es el acceso a la Educación Básica. A pesar de la universalización de la educación, los asuntos que preocupaban a nuestros antecesores republicanos siguen siendo debatidos hoy día. La implantación de las medidas que ellos marcaron y el desarrollo de una educación verdaderamente igualitaria y equitativa todavía no es completa, por lo que es imprescindible que sigamos trabajando en este sentido.

Published: December 2022

The efficacy of statins in the primary and secondary prevention of cardiovascular disease has been proven beyond doubt. The number needed to treat to prevent one cardiovascular event is 1 in 30 over 10 years, and the number needed to treat for secondary prevention is much lower. However, a recent study demonstrated that only 68% of eligible patients are on statin therapy. Moreover, there seems to be a reluctance to escalate statin doses due to the fear of adverse effects. The adverse effects that worries patients and their physicians most frequently are those related to muscular symptoms. N-of-1 trial evidence suggests that muscular symptoms attributed to statins are often caused by the nocebo effect. This article aims to provide a structured, evidence-based approach to suspected statin-related muscle toxicity.
Determinants of bilateral current account balance between the Eurozone and the United States
Authors: Bertsatos Gerassimos
Published: December 2022

Long- and short-run current account balance (CAB) determinants of the nineteen Eurozone (EZ) member states vis-a-vis the United States (US) are examined. Particularly, the competitiveness of the EZ vs the US, the relationship between the current account deficit and the budget deficit (twin deficit), and other factors determining the current account balance are studied. Quarterly data was used in a sample of the nineteen EZ member states with the US as a trading partner over the period 2008 - 2018. It is found that the CAB in the long run has a positive relationship with the real interest rate, real exchange rate, Gross Domestic Product (GDP) per capita, and exchange rate volatility, but a negative relationship with the fiscal balance. In the short run, it is notable that only the real exchange rate affects the current account balance. Finally, policy implications are discussed regarding the determinants of the current account.

Authors: Torshin I. Yu. , Gromova O. A. , Maksimov V. A. , Chuchalin A. G.
Published: December 2022

Deficiency of certain micronutrients interferes with the functioning of acquired immunity, which may negatively affect the efficacy and safety of vaccinations. The results of clinical and epidemiological studies have shown that micronutrient supplementation before vaccination increases its efficacy (antibody titers against viral/bacterial pathogens) and safety (prevention of malaise, reduction of disease severity and mortality in case of post-vaccination infection).

The aim of the study was to analyze the currently available studies on the relationship between micronutrient status and the results of vaccination against bacteria and viruses.

Conclusion. Micronutrient supplementation contributes to the formation of adequate immunity after vaccination and increases the safety of vaccination. Vitamin-mineral complexes represent a cost-effective method to reduce the risks of vaccination in patients with polyhypovitaminosis.
Understanding Asian American College Students’ Suicidal Behavior: Qualitative Study
Authors: Kim Caleb
Published: December 2022

The purpose of this study is to examine Asian American college students’ perception of suicide and culture-bound risk factors associated with suicidal behaviors. By analyzing five focus groups of 28 Asian American college students, this study identifies their dual perspectives on suicide and a range of culture-bound risk factors such as loneliness and sticking out feelings, parent’s higher academic pressure, inter-generational acculturation disparity and burden for living up to model minority image. The findings of this study suggest that Asian American college students’ suicidal behavior needs to be understood from their Asian cultural attributes such as collectivistic values for honoring family reputations and racial discrimination besides individual student’s mental illnesses including depression. Based on this finding, this study recommends culturally competent suicide prevention programs for both college campus and Asian American ethnic communities.
A Study of the Relationship between Social Communication Skills and Sensitivity to Paralanguage
Authors: N. Yoshimoto Jun
Published: December 2022

Sixty office workers at a temporary employment agency were surveyed for their Autism-Spectrum Quotient (AQ) and Sensitivity to Paralanguage (SP) scores. The SP measure contains 12 questions and requires participants to guess the nature of the social relationship between two people based on a 30-second acoustic sample of their dialogue. Paralanguage was selected for investigation in this study rather than nonverbal aspects of communication because people with autism spectrum disorder (ASD) tendencies — who tend to avoid looking at the face of the interlocutor — still use paralanguage effectively. Social communication skills (SCS) were defined as the sum of scores from the AQ subscales “Social skills” and “Communication”, and participants were categorized into either high or low SCS groups. Five participants had AQ scores of 26 or more, including one participant with an AQ score of 36. The five high AQ scorers were all male and all in the low SCS group. The low SCS group had a mean SP score that was 0.47 points higher than the high SCS group. The results indicate that people with poor SCS were more effective in guessing the social relationship between the two parties based on paralanguage than those with high SCS. There are two possible explanations for this finding. The first is that the SP test favors people with ASD tendencies in the low SCS group. The second is that the high SCS group may typically rely on senses other than hearing when making social judgments. In future, the reasons for our finding may be clarified by creating a “sensitivity to nonverbal cues” measurement that uses only visual information.
Time Perspective in Relation to Academic Performance and Subjective Well-Being among Chinese Adolescents
Authors: Wu Zihan
Published: December 2022

In an effort to contribute to the study on time perspective and its influence on adolescents, the present study aimed to investigate the relationship between the time perspective and adolescents’ academic performance and time perspective and adolescents’ subjective well-being. In this study, time perspective has three dimensions, the past, present, and future, and is divided into time relation, time orientation, time frequency, and time attitudes. Subjective well-being consisted of four subscales to assess adolescents’ subjective well-being score, including the joy of learning, school connectedness, education purpose, and academic efficacy. A total of 379 students (176 males and 203 females) from seven middle and high schools in China participated in our study by responding to an online survey. The results showed that adolescents who think more frequently about the future and present and hold positive attitudes towards the present usually had better academic performance. Thinking more frequently about the present exerted a positive influence on adolescents’ subjective well-being. In contrast, past time perspective was not a major determining factor on either adolescent’s academic performance and subjective well-being.
Emergency Cooperation Mechanism under Institutional Collective Action — A Review on Inter Organizational Collaboration
Authors: Kang Wei , Mao Shuo
Published: December 2022

In recent years, due to the high-frequency growth and increasing cross-border nature of all kinds of emergency events, which has made the emergency management ability of a single organization in the face of all kinds of emergencies is not so prominent. How to strengthen the cooperation of different organizations in emergency management has become a major problem to be solved by the governments at all levels. Many scholars in various fields have also carried out a variety of theoretical research and management practice. This paper introduces the role of cooperation mechanism under the institutional collective action framework in the emergency management in the face of different types of emergencies. The emergencies are divided into natural disasters, social security events, disaster accidents and public health emergencies. This study found that cooperation mechanism with different degree of autonomy and complexity can effectively help organizations strengthen their willingness to cooperate, promote formal and informal exchanges, promote the rational flow and effective allocation of resources and promote effective collective action. And the binding and bridging mechanism is more popular with the organization participants in all levels of government when dealing with all kinds of emergencies, while other types of cooperation mechanisms focus on different types of emergencies according to their own characteristics. Through the in-depth study of cooperation mechanism under the institutional collective action framework, it also provides a new idea for the domestic emergency management.
Key challenges for BRICS at the current stage
Authors: Yevseenko Andrey
Published: December 2022

The urgency of further building up cooperation within the framework of the BRICS forum has increased after the start of the Russian special military operation in Ukraine. However, the ties within the grouping cannot be based solely on the promotion of Chinese or Russian interests, nor on a rigid anti-Western platform. The projects initiated within that framework need to be broader in scope. This requires not only building up cooperation inside of already established relationships, but also attracting new participants. Each of the latter has certain advantages and disadvantages in terms of strengthening BRICS potential. Therefore, it is important not only to determine the trajectory of development of the association, but also its priority tasks. The dichotomy between its functionality and scale will continue to hold back the development of BRICS. Nevertheless, the interest of the developing countries of the non-Western world towards the forum from is going to persist.

The USA and the food losses` problem
Authors: Ovchinnikov Oleg
Published: December 2022

The problem of food waste and loss is one of the most important components of the global food problem. Its relevance has been steadily growing in the last 2-3 decades, due to the huge (about 1 billion tons annually) volume of food waste and loss against the background of a number of other problems, in particular, the degradation of the main natural resources used in agricultural production, as well as the presence of a significant number of hungry and malnourished population. Along with the fact that a significant amount of food waste and loss is produced in the USA (about 100 million tons annually), the formation of a coherent system of measures to combat food losses has begun in the country. This article analyzes the accounting methods/principles, as well as the structure and sources of food losses in the world and the USA.
Postmodern metamorphoses as determinants of political science
Authors: Krotkov Vladimir
Published: December 2022

The article examines the trends and characteristics of global transformations that have social, political, economic, informational, axiological and other connotations. Postmodern transformations and practices are ambivalent in nature, which, on the one hand, leads to unified models and institutional formats, on the other – to differentiated and turbulent forms of being. The analyzed post-industrial trends and practices determine heuristic approaches and corresponding research optics within the framework of political science. As a result, many political science paradigmatic aspects of the last century do not quite correlate with the new challenges of our time. The revealed scientific contradiction can become a driver of future scientific reflection in the field of socio-political knowledge.

Authors: Jin Ting , Ma Zhuang , Niu Jinfang , Su Peng
Published: December 2022

Concentration is crucial for children to nurture good personality and develop well. To observe teachers and children in concentration-oriented preschool education activities, it is necessary to analyze the video images of relevant activities. This paper the image segmentation and target extraction of preschool education activity space for improving children's concentration. After discussing the relationship between children's concentration and preschool educational activity intervention, the authors introduced the frequency-tuned saliency algorithm into the constructed Gaussian mixture model, constructed the spatial information of the images on the preschool educational activity space for improving children's concentration, and successfully segmented these images. Since the target children are small and numerous, have color overlap with the background, and face strong light interference, the ViBe algorithm with complex scenes, i.e., ViBe+, was selected to quickly detect the multiple child targets in complex preschool education activity environments. Experimental results verify the effectiveness of the proposed algorithm.
A New Feature Extraction Method for EMG Signals
Authors: Sevim Yusuf
Published: December 2022

Surface Electromyography (sEMG) is an important tool for gesture recognition. Features and classification methods have to be carefully selected to be successful in the recognition of electromyografic signals. In most of the sEMG studies, time and frequency domain features have been extracted and classified with a single classifier. But neither one feature nor one classifier alone has achieved high classification accuracies. Using a feature and classifier combination would be a solution for this problem, and increase the accuracies. As a contribution to this field, a new time domain EMG feature is suggested and its classification performance is examined for feature and classifier combinations in this study. According to the results of this study, the new feature has high classification accuracy, and when it is used with AR and ST features, the average of the classification accuracy reaches 99.57% for multiple SVM classifier. Besides, the new feature+AR+ ST feature combination shows high classification accuracy for single classifier, and this eliminates the need for multiple classifiers.
A Traffic Parameter Detection Algorithm Based on Double Coils
Authors: Wu Hao , Sun Xiaoyan , Zhong Jin , Cao Fengyun
Published: December 2022

This paper designs a detection method for real-time acquisition of traffic intersection parameters based on image processing. Firstly, two virtual coils were drawn at the beginning and the end on the acquired video stream image. Next, the presence of the vehicle was judged based on the change of the gray value in the two virtual coils. The background difference algorithm was adopted to detect and obtain various traffic parameters. The experimental video samples were collected in the actual road environment. Our algorithm relies on the first and last two coils for information processing, and completes vehicle detection, speed detection, and important parameter information acquisition of body color. Experiments show that, compared with the traditional machine vision-based traffic information detection algorithm, our traffic parameter detection method, which is based on double virtual coils, has high detection accuracy, and can detect more parameter information, while satisfying real-time performance.
Implementation of Omar Pigeon Space-Time (OPST) Algorithm to Mitigate the Interference and Peak-to-Average Power Ratio (PAPR) Using RPR Mobile and HST-HM in the 5G
Authors: Duraisamy Kumutha , Thanarajan Tamilvizhi , Alharbi Meshal
Published: December 2022

Nowadays, the 5G parameters play an eminent role in the massive Multiple-input, multiple-output orthogonal frequency-division multiplexing (MIMO-OFDM) system for enriching high signal to noise ratio (SNR). 5G application has emerged in the role of artificial intelligence for involving the reduction of Peak to Average Power Ratio (PAPR) and Bit Error Rate (BER). In MIMO – OFDM system, the high PAPR is a tremendous drawback during the transmission of bit symbol with the number of sub-carriers in the signal. To avoid Intercarrier Interference (ICI) during transmission of the number of sub-carriers, the Omar Pigeon Space-Time (OPST) algorithm is implemented. Then, to overcome high PAPR in the uplink, the Hybrid Space-Time - Hadamard matrix (HST-HM) techniques are proposed and the Bit Error Rate (BER) is decreased abruptly. 5G parameters and specifications are incorporated in this OPST algorithm for avoiding interference during the data bit transmission in the MIMO – OFDM system. Realtors Property Resource (RPR) mobile app is developed for an experimental display of the information that occurs in the real-time uplink MIMO – OFDM system. Thus, the descriptive analysis and simulated results of PAPR, SNR, and BER are executed using the proposed system of HST with HM in the 5G Communication. The RPR mobile executes the outcomes through the OPST algorithm with a better system performance of the MIMO-OFDM system based on the 5G.

Authors: İnce Esra , Karakaya Barış , Türk Mustafa
Published: December 2022

Security and privacy problems in communication systems and social media platforms where digital image/video are shared almost always, have attracted researchers interest on information security. Starting from this point of view, a novel one-dimensional chaotic maps based pseudo random bit generator is proposed to make a significant contribution to the literature about protection of personal data in any network. Electronic circuit realizations of Logistic and Tent maps as entropy source are designed on Orcad-Pspice environment and state variables are inputted to novel post-processor algorithm. The rest of main blocks of proposed pseudo random bit generator design are built up fixed-point binary conversion algorithm, XOR processor and H function post-processor. The generated pseudo random bit series are tested by using NIST 800.22 statistical test suite and applied to color image encryption in order to show the effectiveness of proposed design. Cryptanalysis processes such as histogram, NPCR-UACI and correlation analysis are demonstrated. Analysis results show that the proposed design can be used successfully in many secure communication and media transmission applications.
Application of Signal Imaging Analysis Technology in Prediction and Treatment of Water Inrush in Diversion Tunnel
Authors: Yao Jun , Wang Yuan , Feng Di
Published: December 2022

A signal imaging analysis technology was proposed to accurately interpret geological radar detection images in order to address the issues of difficult interpretation of radar advance forecast images of water inrush in diversion tunnels in unfavorable geological zones and difficult detection of grouting effects in grouting circles. The waveform, amplitude, and frequency differences in the radar data among various geological bodies in the fracture development zone, broken zone, and water-rich zone can be analyzed by the signal imaging analysis technology, which can extract multiple technical parameters for comprehensive judgment and provide a foundation for the interpretation of geological radar images. In this study, signal mapping analysis technology was used to interpret the geological detection images taken in front of the tunnel face and the surrounding rock geological detection map after cement-polyvinyl alcohol grouting, respectively. The accuracy of the signal mapping analysis technology was confirmed, and the following conclusions were drawn: (1) Geographic Different geological structures, such as fissure zones, broken zones, and water-rich zones, have different reflection signal properties for radar electromagnetic waves. With the help of the image, distinct geological features can be identified and water inrush can be anticipated; (2) Electronic scanning imaging can be used to observe it. The geological radar image feedback of the grouting circle after grouting indicates that the lithology of the grouting circle is complete and the grouting reinforcement and sealing effect is good when the cement-polyvinyl alcohol slurry concretion particles are dense; (3) The numerical analysis results of the seepage field of the tunnel demonstrate that the grouting of the surrounding rock can effectively reduce water seepage and control water gushing. The study's findings offer a specific reference point for the forecasting and management of water gushing in diversion tunnels located in adverse geological regions.
A Neighborhood Impact Driven K-Medoid Clustering and Fuzzy Logic Blended Approach for High Density Impulse Noise Detection and Removal
Authors: Bandyopadhyay Aritra , Deb Kaustuv , Chakraborty Avishek , Das Atanu , Bag Rajib
Published: December 2022

In the field of image processing, removing impulse noise has been regarded as one of the most important tasks, primarily because of the noise pattern it presents. Existing filters used the effect of only those non-noisy pixels which were present inside the specified windows ignoring the effect of the non-noisy pixels present in the surrounding windows. So, the least distant non-noisy pixels in the present window as well as in the surrounding windows may have an influence on the present window's noisy pixels. Hence, considering the above factors, in this paper, a two-step technique named KMDCIFF (K-medoid clustering identified fuzzy filter) is proposed for removing impulse noise from digital images. In the proposed KMDCIFF algorithm, the first step is noise detection using K-medoid clustering, followed by a fuzzy logic-acquainted noise reduction strategy that utilizes the least distant local and non-local non-noisy pixels for removal operation. The detection process involves the application of K-medoid clustering on all 5×5 windows produced by centering each pixel of the considered image. In order to remove noise, a 7×7 window is constructed with each detected noisy pixel in the center. Analyzing the impact of the least distant local and non-local pixel on each noisy pixel, the same is replaced by an estimated pixel’s intensity value obtained from the most influential non-noisy pixels. KMDCIFF is evaluated using well-known metrics for diverse types of images. At a high noise density of 80%, KMDCIFF exhibited significant peak-signal-to-noise-ratios (PSNRs) of 26.97 dB and 29.67 dB and structural similarity indexes (SSIMs) of 0.8045 and 0.9288 on random and fixed valued impulse noise impacted Lena image, respectively. Comparing the results of the contemporary study to those of previous studies of a similar kind in this sector, the results are unswervingly astounding.
CT Image Denoising Model Using Image Segmentation for Image Quality Enhancement for Liver Tumor Detection Using CNN
Authors: Gavini Venkateswarlu , Lakshmi Gurusamy Ramasamy Jothi
Published: December 2022

Image denoising is an important concept in image processing for improving the image quality. It is difficult to remove noise from images because of the various causes of noise. Imaging noise is made up of many different types of noise, including Gaussian, impulse, salt, pepper, and speckle noise. Increasing emphasis has been paid to Convolution Neural Networks (CNNs) in image denoising. Image denoising has been researched using a variety of CNN approaches. For the evaluation of these methods, various datasets were utilized. Liver Tumor is the leading cause of cancer-related death worldwide. By using Computed Tomography (CT) to detect liver tumor early, millions of patients could be spared from death each year. Denoising a picture means cleaning up an image that has been corrupted by unwanted noise. Due to the fact that noise, edge, and texture are all high frequency components, denoising can be tricky, and the resulting images may be missing some finer features. Applications where recovering the original image content is vital for good performance benefit greatly from image denoising, including image reconstruction, activity recognition, image restoration, segmentation techniques, and image classification. Tumors of this type are difficult to detect and are almost always discovered at an advanced stage, posing a serious threat to the patient's life. As a result, finding a tumour at an early stage is critical. Tumors can be detected non-invasively using medical image processing. There is a pressing need for software that can automatically read, detect, and evaluate CT scans by removing noise from the images. As a result, any system must deal with a bottleneck in liver segmentation and extraction from CT scans. To segment and classify liver CT images after denoising images, a deep CNN technique is proposed in this research. An Image Quality Enhancement model with Image Denoising and Edge based Segmentation (IQE-ID-EbS) is proposed in this research that effectively reduces noise levels in the image and then performs edge based segmentation for feature extraction from the CT images. The proposed model is compared with the traditional models and the results represent that the proposed model performance is better.

Due to its intricacy, dermatology presents the most challenging and uncertain terrain for diagnosis. Skin conditions like Carcinoma and Melanoma are frequently very challenging to identify in the early stages and are much more challenging to define independently. The use of pattern recognition models to automate detection has been studied by a number of writers. This research describes a novel Deep Convolutional Neural Network (DCNN) for Skin Disease Detection. The photographs of skin would undergo processing to remove unwanted noise as well as to improve the photos. The performance of classification will be greatly impacted by the pixel values of a picture. The picture is classified using the softmax classifier method by feature extraction utilising DCCN, and a diagnosis report is produced as the result. In comparison to more classic approaches like KNN (K-Nearest Neighbour) and CNN, this methodology will provide results faster and with improved accuracy, precision, and recall. With a detection time of 10,000 milliseconds, DCNN achieved accuracy, precision, and recall percentages of 98.4%, 96.3%, and 97.2%, respectively.

Życie i twórczość Józefa Wieniawskiego na wielu płaszczyznach wciąż wymaga opracowania. W ten zakres wpisuje się działalność polskiego pianisty i kompozytora, jaką prowadził na terenie Półwyspu Skandynawskiego. Należy wspomnieć również o zaangażowaniu jego starszego brata Henryka – skrzypka. Poruszając niniejsze zagadnienie, warto jednocześnie zwrócić uwagę na relacje z tamtejszym środowiskiem artystycznym, za sprawą jednego z jego czołowych przedstawicieli. Celem niniejszego artykułu jest zatem wypełnienie kolejnej luki w badaniach dotyczących kompozytora.

Published: December 2022

Este artigo, decorrente de um estudo de caso com abordagem qualitativa, teve por objetivo analisar a prática da coordenação pedagógica no contexto da Educação Especial, focalizando-se na relação com o professor da Sala de Recursos Multifuncionais, a partir da observação de atendimento a um aluno com síndrome de Down, em uma escola municipal de Natal/RN. Buscou avaliar o papel do pedagogo, enquanto coordenador, para a realização dessa tarefa na prática. Como instrumentos de coleta de dados foram realizadas entrevistas semiestruturadas com a coordenadora pedagógica e o professor da SRM e a observação do atendimento de um aluno com Síndrome de Down no segundo semestre de 2019. Como técnica de análise de dados, utilizamos a análise de conteúdo. Os principais achados da pesquisa apontaram que que o coordenador por assumir diversas funções, perde o foco em suas atribuições pedagógicas e que há um distanciamento dos assuntos voltados às pessoas com deficiência. Além disso, o estudo revela uma necessidade formativa dos agentes educacionais para o atendimento de estudantes com deficiência e uma maior interlocução entre os professores da SRM, das classes regulares e coordenação pedagógica.
Consensualidade na justiça 100% digital: problemas e perspectivas
Authors: Almeida Marcelo Pereira , Pinto Adriano Moura da Fonseca , Filpo Klever Paulo Leal
Published: December 2022

O paper dialoga com duas políticas judiciárias de iniciativa do CNJ, que promovem a adoção de métodos consensuais de solução de conflitos, sobretudo a conciliação e a mediação, bem como a informatização crescente dos processos judiciais. A proposta do trabalho é refletir sobre essas inovações, pensando em problemas e dificuldades que podem atravessar o caminho da consensualidade nesse contexto. Foi utilizado o método dedutivo, parcialmente exploratório, a partir do mapeamento normativo que regula esses seguimentos e da abordagem bibliográfica de autores que enfrentaram os temas discutidos no presente texto em diferentes perspectivas, associado a experiências e observações empíricas dos autores em sua prática forense.
Repensando a ideia de normal e patológico na educação – contribuições do pensamento de Canguilhem
Authors: Manzi Ronaldo
Published: December 2022

Há um crescimento no uso de medicamentos em crianças e adolescentes como nunca visto antes. As escolas, como mostram estudos recentes, contribuem para que haja esse crescimento. Na verdade, mesmo o Estado incentiva que os professores estejam preparados para identificar qualquer indicativo de transtorno. O fato de que uma grande porcentagem de pessoas com idade escolar possui um transtorno de ordem biológica se fundamenta em uma concepção de normal e patológico em que se toma uma média como referencial ideal. Entretanto, a ideia de normal e patológico pode ser colocada em questão a partir de um estudo que vem da própria medicina – é o caso das reflexões de Georges Canguilhem. Apesar de seu trabalho não ter tido impacto nas áreas médicas, ele foi fundamental nas áreas humanas, porque oferece uma concepção de normal com potencial transformativo. Normal não seria aquele que segue uma norma ideal, mas aquele que é capaz de instaurar uma nova norma. A concepção de Canguilhem, como pretende-se mostrar, pode nos levar a repensar o que consideramos um transtorno e tem um potencial crítico na escola, pois lhe traz a responsabilidade de ouvir cada caso. Apresentar-se-á, nesse artigo, a posição inovadora de Canguilhem e como ela ainda nos dá uma possibilidade de repensarmos a ideia de transtorno em pessoas em idade escolar.
Principais mudanças percebidas pelos pais relacionadas às práticas educativas parentais no contexto da covid-19

Published: December 2022

Esta pesquisa teve como objetivo identificar a percepção dos pais em relação às mudanças nas suas práticas educativas parentais e sua repercussão em relação aos filhos, na faixa etária dos 6 aos 12 anos, durante a pandemia da Covid-19. Trata-se de um estudo descritivo e qualitativo desenvolvido a partir da aplicação de um questionário do tipo Likert com 26 itens, os quais foram respondidos por 35 participantes que preencheram os critérios de inclusão. Os resultados indicam que as práticas educativas parentais mais prevalentes durante o contexto pandêmico foram a monitoria positiva e o comportamento moral, em detrimento daquelas consideradas negativas, tais como a negligência, a disciplina relaxada, a punição inconsistente e a monitoria negativa. A análise dos dados também permitiu destacar o predomínio do estilo parental autoritativo para a resolução de situações conflituosas. Foi possível identificar que, mesmo diante de um cenário desafiador, a maioria dos pais buscou o diálogo e o afeto como meio para resolução dos conflitos que surgiram com seus filhos durante o isolamento social e tantas outras adversidades trazidas pela pandemia.
Silla’s Tale of 'Okdae(玉帶)' and Its Political Significance
Authors:   HUFS Institute of History and Culture, KO HYUN AH
Published: December 2022

In Silla, there are two tales relating to Okdae. These are records of a Cheonsaokdae(天賜玉帶) during King Jinpyeong’s reign in the middle ancient period and of a Heukokdae(黑玉帶) during King Sinmun’s reign in the middle period. These two records were noted early on in each period because they shared the motif of the Okdae. Cheonsaokdae is said to be one of the three treasures of Silla, along with the Jangyukjonsang(丈六尊像) and the Nine-story Wood Pagoda of Hwangnyongsa Temple. Hwangnyongsa Temple reflected the political ideology of Cakravartin(轉輪聖王) from King Jinheung’s reign onward and served as the national temple for protecting Silla. The two treasures of Hwangnyongsa Temple are noteworthy because the ideology of King Jeonryunseong of the middle ancient period was maintained even after King Jinheung and was based on the concepts of Sacred Bone(聖骨) and Seokgajok(釋迦族), which were emphasized from King Jinpyeong to King Seondeok. In the case of Cheonsaokdae, perceptions about Silla’s three treasures appear to have been formed during the reign of King Seondeok, given that it is related to the Jeseok faith(帝釋信仰), which was predominantly practiced during King Seondeok’s reign.
Meanwhile, in the records on Heukokdae from King Sinmun’s reign, black jade was considered to be associated with the Five Elements(五行說). The Five Elements theory, based on Confucianism, was introduced in Silla in the middle ancient period. Particularly worth noting is the fact that Qin Shi Huang, who united China for the first time, chose black as the primary color based on the Five Elements theory. During King Sinmun’s reign, a new ideology was required to match the status of the newly unified empire. Consequently, the tale of the “black jade,” influenced by the Five Elements theory, emerged.
Okdae can be viewed as a symbol of the ruler, and the tale of the two okdae is symbolic of the connection between the middle ancient period and the middle period, while the heukokdae of the middle period represents the process by which a new political idea was established.
