Google Images Search Results as a Resource in the Anatomy Laboratory: Rating of Educational Value
Authors: Wink Alexandra Elisabeth , Telfer Amanda N , Pascoe Michael A
Published: October 2022

Background

Preclinical medical learners are embedded in technology-rich environments, allowing them rapid access to a large volume of information. The anatomy laboratory is an environment in which faculty can assess the development of professional skills such as information literacy in preclinical medical learners. In the anatomy laboratory, many students use Google Images searches in addition to or in place of other course materials as a resource to locate and identify anatomical structures. However, the most frequent sources as well as the educational quality of these images are unknown.

Objective

This study was designed to assess the sources and educational value of Google Images search results for commonly searched anatomical structures.

Methods

The top 10 Google Images search results were collected for 39 anatomical structures. Image source websites were recorded and categorized based on the purpose and target audience of the site publishing the image. Educational value was determined through assessment of relevance (is the searched structure depicted in the image?), accuracy (does the image contain errors?), and usefulness (will the image assist a learner in locating the structure on an anatomical donor?). A reliable scoring rubric was developed to assess an image’s usefulness.

Results

A total of 390 images were analyzed. Most often, images were sourced from websites targeting health care professionals and health care professions students (38% of images), while Wikipedia was the most frequent single source of image results (62/390 results). Of the 390 total images, 363 (93.1%) depicted the searched structure and were therefore considered relevant. However, only 43.0% (156/363) of relevant images met the threshold to be deemed useful in identifying the searched structure in an anatomical donor. The usefulness of images did not significantly differ across source categories.

Conclusions

Anatomy faculty may use these results to develop interventions for gaps in information literacy in preclinical medical learners in the context of image searches in the anatomy laboratory.

Background

There is a strong association between increased mobile device use and worse dietary habits, worse sleep outcomes, and poor academic performance in children. Self-report or parent-proxy report of children’s screen time has been the most common method of measuring screen time, which may be imprecise or biased.

Objective

The objective of this study was to assess the feasibility of measuring the screen time of children on mobile devices using the Family Level Assessment of Screen Use (FLASH)–mobile approach, an innovative method that leverages the existing features of the Android platform.

Methods

This pilot study consisted of 2 laboratory-based observational feasibility studies and 2 home-based feasibility studies in the United States. A total of 48 parent-child dyads consisting of a parent and child aged 6 to 11 years participated in the pilot study. The children had to have their own or shared Android device. The laboratory-based studies included a standardized series of tasks while using the mobile device or watching television, which were video recorded. Video recordings were coded by staff for a gold standard comparison. The home-based studies instructed the parent-child dyads to use their mobile device as they typically use it over 3 days. Parents received a copy of the use logs at the end of the study and completed an exit interview in which they were asked to review their logs and share their perceptions and suggestions for the improvement of the FLASH-mobile approach.

Results

The final version of the FLASH-mobile approach resulted in user identification compliance rates of >90% for smartphones and >80% for tablets. For laboratory-based studies, a mean agreement of 73.6% (SD 16.15%) was achieved compared with the gold standard (human coding of video recordings) in capturing the target child’s mobile use. Qualitative feedback from parents and children revealed that parents found the FLASH-mobile approach useful for tracking how much time their child spends using the mobile device as well as tracking the apps they used. Some parents revealed concerns over privacy and provided suggestions for improving the FLASH-mobile approach.

Conclusions

The FLASH-mobile approach offers an important new research approach to measure children’s use of mobile devices more accurately across several days, even when the child shares the device with other family members. With additional enhancement and validation studies, this approach can significantly advance the measurement of mobile device use among young children.

Authors: Verma Prateek , Sharma Rishabh , Mistry Maunil
Published: October 2022

Abstract: Internet of Things (IoT) describes physical gadgets with sensors, processing power, software and other technologies that connect with other devices and exchange data over the internet. Consumers and businesses everywhere are getting used to the notion that critical data processing and analysis are now being fulfilled by a new-age technology infrastructure. The Internet of Things (IoT) is the key driver of this trend, with 64 billion IoT devices estimated around the world by 2026. IoT activities span everything from smart homes and smart cities to fitness monitoring and inventory control. This rapid growth of IoT has its own set of challenges and the first one being the threat of cybersecurity. As the Internet of Things rapidly grows, cyber threats and associated risks continue to evolve and become increasingly complex. The biggest threat to these IoT devices, which has grown exponentially in the past few years, is the Distributed Denial of Service (DDoS). This highly daunting cyber-threat is extremely dangerous because perpetrators can now use IoT devices to make the attacks more severe. The formation of botnet clusters (hijacked IoT devices) is the heart of a large-scale DDoS cyber-attack. This research work focuses on the emerging trends associated with the volume of cyber-attacks. Furthermore, the research delves into the possible solutions to tackle, and possibly eradicate the cyber-threats present in the IoT systems. The domain of Machine Learning is investigated thoroughly in order to extract the ongoing research and possible solutions pertaining to the cyber-security of IoT devices and systems.

Published: October 2022

Seaweed constitutes one of the commercially important living renewable resources in the marine ecosystem.Seaweeds have antimicrobial, antioxidant, and anti-inflammatory properties. The aim of the study is to estimate the phytochemicals and antioxidant activity of Padina gymnospora and Ulva lactuca. The antioxidant properties and phytochemical analysis of Padina gymnospora and Ulva lactuca collected from the Gulf of Mannar during the low tide period were analyzed.The study's objective is to analyze the phytochemical and antioxidant activities using methanol as solvent. Antioxidant activities were determined using 2,2-diphenyl-1-picryl-hydrazyl (DPPH) assay treated with methanol and Phytochemical analysis carried out by Folin-Ciocalteu reagent. Antioxidants and phytochemicals in seaweeds provide healthpromoting effects and protect against non-communicable diseases such as Cancer, arthritis, diabetes, obesity, etc. The results reveal that antioxidant activities were higher in Padina gymnospora in methanol solvent than in Ulva lactuca. The percentage of inhibition of Padina gymnospora and Ulva lactuca was 61.5 and 64.5 respectively. IC50 value of Padina gymnospora and Ulva lactuca was 60.4 and 60.6 respectively.The preliminary phytochemical analysis of Padina gymnospora and Ulva lactuca was found to contain Alkaloids, Steroids, Terpenoids, Glycosides. To know the efficiency of green seaweed Ulva lactuca with brown seaweed Padina gymnospora the study was carried out. The highest flavonoid content was recorded in brown seaweed Padina gymnospora (25.5±0.02mg REg-1) compared toUlva lactuca (19.32±0.5mg REg-1). The total phenolic content was highest in Padina gymnospora (3.7±0.06mg GAEg-1) whereas Ulva lactuca contained (2.81±0.3mg GAEg-1). Therefore, the present work recommends consuming seaweeds in our regular diets to have a healthy lifestyle. From the current study of phytochemical and antioxidant rich seaweeds can be incorporated in the formulation of drugs used for treating various non- communicable diseases prevailing in the present era.

Published: October 2022

Serum (C Reactive Protein) CRP is a good predictor of vascular events and has been linked to polycystic ovarian syndrome (PCOS). The increased CRP may be an early marker of upcoming atherosclerotic diseases like coronary artery disease and stroke. To identify the disease of PCOS and its interrelation with increased CRP may work as a clue for its disease progression. The purpose of this study is to evaluate the high-sensitivity C- reactive protein, which is a characteristic of individuals with PCOS of reproductive age. The sample size for this prospective randomized study was 200 people, divided into two equal groups (with or without PCOS). This study included 100 obese women with the polycystic ovarian syndrome and 100 matched controls. These women's blood samples were tested for serum lipid profile and hsCRP.. The demographic variables were similar between the groups. Our findings revealed that patients with PCOS had high LDL and triglyceride levels. HDL levels were extremely low. This indicates a poor lipid profile in PCOS patients. (The p-value is 0.001). The hs CRP was 9.3 mg compared to 2.9 mg in the control group. According to our findings, hs CRP may provide information about the presence of the disease. As a result, more research is needed to explain the potential role of C-reactive protein in the disease incidence and progression of polycystic ovarian syndrome. Even though there are a lot of studies linking these two, we have done for Hs CRP and PCOS. The sample size is on the higher side in our study.

Published: October 2022

Nasal endoscopy is a minimally invasive, routine outpatient diagnostic procedure. With 0 degree scope being used as the first and often only endoscope in diagnostic nasal endoscopy, this study will explicate use of angled scopes to identify anatomical variants and common disease pointers. A Cross-sectional descriptive study involving 756 subjects, between age group of 12-80 years with chronic nasal complaints. All subjects underwent diagnostic nasal endoscopy with 0-, 30- & 70-degree endoscopes. Common anatomical variants along with disease markers were identified. Anatomical variants embedded in lateral wall of nose such as accessory maxillary ostium (AMO) & medialized uncinated (MU), were seen better on 30 & 70 degree scopes (AMO -12% & 12.8% respectively & MU -7.6 and 8.1% of study population respectively), when compared to 0 degree scopes (AMO-5.6% & MU-7 %). Disease pointers projected a general trend of being better visualized on angled scopes of 30 & 70 degree endoscopes. It included discharging meati (27.9 % & 26.3% subjects on 30 & 70 degree vs 25 % subjects on 0 degree), polyposis (20.2 & 19.6% on 30 & 70 degree vs 13% on 0), eschar (6.1% & 5.7% on 30 & 70 degree vs 4.5% on 0), CSF rhinorrhoea (1.3% & 2.1% on 30 & 70degree vs 0.5% on 0). With inclusion of angled scopes in routine nasal endoscopies, one gains capability to diagnose early disease processes, mucosal changes and learn intra nasal anatomy better. The angulation of lenses provides a better field of vision with appropriate magnification and illumination.

Published: October 2022

Non-invasive blood pressure measurement with a brachial cuff sphygmomanometer is an important assessment tool in the diagnosis and management of hypertension and disturbed hemodynamic status. However, when compared to intra-arterial BP, the accuracy of BP measured by non-invasive methods remains questionable. The study attempted to estimate the difference in blood pressure measured by the two methods, as well as analyse the impact of left ventricular morphology and functions on the magnitude of the BP difference recorded by invasive and non-invasive methods. Methods: The subjects were patients undergoing diagnostic coronary angiography for the evaluation of chest pain. The morphology and functions of the left ventricle were determined as part of the routine pre procedural screening. NIBP and IAP were measured twice during the CAG at the radial and aortic levels. Noninvasive BP was measured using a brachial cuff of mercury sphygmomanometer by the auscultatory method. Results of our study revealed that in non-invasive BP both the systolic and the diastolic pressures were higher than their corresponding recordings obtained by invasive methods. The ECHO-derived left ventricular hypertrophy and left ventricular diastolic function correlated positively with the systolic and diastolic pressure differences respectively. Conclusion: Hence we suggest evaluation of the above parameters by echocardiography after obtaining a high BP by non-invasive methods can be done before the commencement of antihypertensive drugs A pre-treatment echo will give a clue on the differences.

Published: October 2022

Medical students tend to experience greater overall psychological distress when compared to the levels of distress observed in the general population. A careful analysis of the coping behaviors and their associations with personality factors etc., in the light of their biological basis, may offer important clues for successful interventions in order to yield fruitful academic outcomes. The fundamental aim was to evaluate the associations between the choice of coping strategies and the Big Five Personality traits among academic high- and low-achievers, and average students who have recently been exposed to the medical curriculum. The other three aims were to evaluate the relationship between the employment of coping strategies and psych morbidity among the above group; to explore the gender-based differences among the above student category; to assess the variations in the associations of adaptive/maladaptive coping with relationship to personality and other factors in the light of higher biological control mechanisms. The voluntary participants of the study include one hundred and forty-two first year medical students (68 males, 74 females) from a private University in Puducherry state, South India. The self-rating anxiety scale and self-rating depression scales were found out. The personality traits were elucidated using the NEO-FFI (NEO Five Factor Inventory), which was administered to all the participants. Those with T-scores above 50 were classified as having elevation in the concerned personality trait. After evaluating the scores of the various personality traits. The average marks secured by the students in four consecutive academic examinations was entered. Correlations between the coping strategies and the above mentioned factors among low- achievers revealed a) a small negative association between TOC and Neuroticism (p<0.05); b) a small positive correlation between EOC and anxiety scores (p<0.05); c) a negative association between TOC and anxiety and depression (p<0.05); and d) a negative association between AOC-SD and depression scores (p<0.05) were noted. . Studies concerning the link between coping strategies, personality and psychopathology may help in identifying certain risk and resilience factors that could influence the impact of stressful academic training for individual students.

Published: October 2022

Ventilator-associated pneumonia (VAP) is one of the common complications occurring in patients predominantly in intensive care units. It is a respiratory tract infection that develops in patients who are intubated for more than 48 hours to 72 hours. It is commonly caused by pseudomonas aeruginosa, If the infection occurs within the first 48 to 72 hours, it is called “earlyonset” and if after 72 hours is termed as “late-onset”1. Even though there are innumerable methods to decrease the infection and its associated morbidity we wanted to examine whether any changes in position were effective in its reduction. The experimental study was conducted on 30 samples collected in a consecutive manner. The study was performed in the Intensive care unit of a medical college hospital for a period of 2 months. The study included both male and female patients between 18 – 55 years who underwent mechanical ventilation for >48 hrs. Following inclusion criteria, patients were screened and randomly divided into 3 equal groups, Group A (35-degree recumbency), Group B (40-degree recumbency), and Group C (45-degree recumbency). The degree was measured by a protractor which was confirmed with available protractor software. The pre and the post (Clinical Pulmonary Infection Scores) CPIS scores were noted. The demographic variables were similar between the groups. There was a significant reduction of scores in Group B and C than A (p value <0.001) there were no major side effects. There were no dropouts. We conclude that both 40-degree and 45-degree recumbency significantly decrease CPIS scores than 35 degrees. Even though Group C is better than group B it’s statistically insignificant.

Published: October 2022

Dental caries detection at an early stage by applying dermatoglyphics and assessing the salivary pH levels can facilitate the initiation of preventive measures at a younger age. However, there are little data available to substantiate the utility of dermatoglyphics and salivary pH in studying the genetic basis of dental caries.Therefore,the present study was aimed to assess the correlation between dermatoglyphic patterns and salivary pH in children with and without Early Childhood Caries (ECC).This cross-sectional study was carried out in 156 children of randomly selected schools in Puducherry in the age group of 3-5 years. Children with decayed, extracted and filled (defs) score of = 5 for group 1 (children with ECC) and defs score of 0 for group 2 (children without ECC) were considered for the study. Their fingerprint patterns and salivary pH were recorded and analysed using Chi-square test and Spearman correlation tests.In children without ECC group, loop frequency 10 and 7 was the most observed category whereas in subjects with ECC group, whorl frequency 7 and 8 was the most observed category. Significant proportion of whorls was seen more in both males and females in ECC group(p<0.0001). The mean salivary pH of subjects with ECC was 6.35±0.38 which was statistically significant (p<0.0001). Dermatoglyphic pattern and salivary pH can be used as predictive tool for diagnosis of ECC as there exists a definite variation in dermatoglyphic patterns and salivary pH in children with ECC and caries-free group. There are various methods to diagnose ECC but so far, there is no method to predict ECC using a dermatoglyphic pattern, salivary pH and ECC that may further facilitate initiation of preventive measures to avoid the progression of ECC at a younger age.

Published: October 2022

Anxiety and fear have become the most significant problem for normal children and differently-abled children at the dental operatory. Various techniques in distraction such as audio, and visual are employed for the behavior management of children. The study aimed to evaluate the effectiveness of four different techniques in anxiety management in differently abled dental pediatric patients. The study included 120 children, randomly assorted into four groups i.e consisting of 30 children in each. Each of these groups was subjected to different distraction techniques, like audio distraction, audio-visual distraction, video distraction and tell-show-do techniques. The parameters assessed were systolic and diastolic blood pressure (SBP and DBP), pulse rate (PR) and oxygen saturation (SPO2) levels. Variables were compared before, during and after the dental procedure using Kruskal-Wallis test. Post-hoc analysis and Bonferroni tests were used to determine the statistical significance in inter-group comparison. SBP was insignificant statistically intra-group at before-after time points. However, SBP during-after treatment showed statistical significance in intergroup (p=0.02). SBP in audio-visual distraction was statistically significant when compared with video distraction group. There was no statistically significant difference observed in the DBP and PR for intra and intergroup, however, SPO2 levels at alltime points in intergroup were statistically significant (p<0.001). Audio-visual distraction proved to be effective as a part of the behavior management technique followed by audio distraction. These non-pharmacological behavior management techniques provided a peaceful dental environment for differently abled children, who have anxiety and fear.
Solution of Molodensky’s boundary-value problem for gravity disturbances with a relative error the Earth`s flattening square (second) order
Authors: Mezhenova I.I. , Popadyev V.V.
Published: October 2022

The solution of the geodetic boundary value problem for determining the anomalous potential from gravity measurements in the spherical approximation, taking into account the relief and compression, was developed in sufficient detail in 1960 and is also based on the results of G. G. Stokes. Flattening of the reference surface was taken into account by D. V. Zagrebin in several works dated 1940–1970; in 1956 M. S. Molodensky proposed a simpler method for an oblate ellipsoid, based on the already known one for a sphere. It turned out that at the very beginning of developing the mentioned solution, an error was made when obtaining the derivative of the reciprocal distance between two points on the ellipsoid in the direction of the outward normal; later it was repeated in issue 131 of the Proceedings of the TsNIIGAiK. That inaccuracy did not influence the conclusions of V. V. Brovar in 1996 and 1999, where the relief was added to the consideration of compression. This solution of Molodensky’s problem, taking the compression into account, was seldom used, and that is probably why the mistake went unnoticed. V. V. Popadyev saw it and found the correct expression for the mentioned derivative, I. I. Mezhenova adapted subsequent conclusions for the gravity disturbances.

Authors: Pazarskis Michail , Gkatziou Maria , Konstantinidis Christos , Kourtesi Sofia
Published: October 2022

This paper investigates the accounting performance of companies listed on the Athens Stock Exchange after mergers by the industrial sector during the period of the financial crisis in Greece. More specifically, all mergers of listed companies during the period 2012–2016 are examined, with the analysis of a final sample of twenty-six companies listed on the Athens Stock Exchange. The evaluation of the accounting statements and the performance of Greek listed companies is done by extracting and comparing various figures from them (financial ratios) before and after the implementation of mergers. This research is based on the methodology of Healy, Palepu, and Ruback (1992) and Ramaswamy and Waegelein (2003) in order to explore if there is a positive or negative result from the merger transaction. The research results did not show any statistically significant change in any of the research financial ratios after the mergers. However, the effect of the absorbing company’s industry was examined in relation to the analyzed financial ratios and no better performance was observed for those in any industry. Finally, mergers as a competitiveness strategy in the business arena managed to provide the involved companies with a stable accounting performance during the crisis period in Greece.

Average path length of a special class of hierarchical networks
Authors: Liu Jia-bao , Zheng Ya-Qian , Wang Kang
Published: October 2022

Many of the behaviors observed in actual systems are comparable to
scale-free and small world structures in network research. In contrast
to conventional hierarchical networks, the unusual fractal hierarchical
network we created in this research has a pyramidal structure. The
findings we get from this network are expanded to be applicable to
arbitrary hierarchical networks. The average path length of unweighted
and weighted hierarchical networks are the main topics of this paper. We
demonstrate that, in the unweighted case, when the number of iterations
z tends to infinity, the average path length is only related to the
number of blocks of the hierarchical network. Additionally, in the
weighted network, the average path length is related to the number of
blocks r and the weighting factor w of the hierarchical network.
Existence of Coupled Optical Vortex Solitons Propagating in a Quadratic Nonlinear Medium
Authors: Medina Luciano
Published: October 2022

We consider the coupled propagation of an optical field and its second
harmonic in a quadratic nonlinear medium governed by a coupled system of
Schrodinger equations. We prove the existence of ring-profiled optical
vortex solitons appearing as solutions to a constrained minimization
problem and as solutions to a min-max problem. In the case of the
constrained minimization problem solutions are shown to be positive but
the wave propagation constants undetermined, but in the min-max approach
the wave propagation constants can be prescribed. The quadratic
nonlinearity introduces some interesting properties not commonly
observed in other coupled systems in the context of nonlinear optics,
such as the system not accepting any semi-trivial solutions, meaning,
that optical solitons cannot be observed when, say, one of the beams are
off. Additionally, the second harmonic always remains positive.

Nonparametric Additive Distortion Measurement Errors Models
Authors: Zhang Jun , Gai Yujie , Yang Yiping
Published: October 2022

We consider nonparametric estimation of some regression curves when the
data are observed with additive distortion which depends on an observed
confounding variable. The unobservable response variable and covariates
are both distorted in a additive fashion by unknown distorting
functions. We study the estimates of nonparametric mean function and its
first derivative, the variance function, the Sharpe ratio function and
correlation curve function. We obtain asymptotic normality results for
the proposed nonparametric estimators. Monte Carlo simulation
experiments are conducted to examine the performance of the proposed
estimators. The proposed estimators are applied to analyze a QSAR fish
toxicity dataset for an illustration.
Rodas de Samba na educação Étnico-Racial do Distrito Federal brasileiro
Authors: Ramos Alves Vitor João
Published: October 2022

A propagação de um conhecimento fragmentado, eurocêntrico, não democrático, não crítico, sexista e racista é a raiz de toda exclusão. Esse modelo técnico de ensino é pautado nas colonialidades do poder, do saber e do ser, hoje vigentes de forma estrutural na sociedade, repetindo fórmulas e discursos hegemônicos, e reproduzindo violentos mecanismos de exclusão social. Portanto, este artigo tem como proposta: fazer pensar a construção de um projeto de educação étnico-racial para escolas públicas do Distrito Federal brasileiro, a partir da tese de doutorado sobre rodas de samba como expressão de resistência espacial negra, defendida no Departamento de Geografia da Universidade de Brasília (UnB), em 2019. Serve de esforço e incentivo para a construção de alternativas, numa escala local, de preservação, valorização, emancipação e autonomia dos sujeitos periferizados e dos próprios coletivos de rodas de samba, presentes no território federal brasileiro
educação problematizadora em Paulo Freire
Authors: Freitas André Luis Castro de , Freitas Luciane Albernaz de Araujo
Published: October 2022

Por meio de um estudo descritivo crítico, fundamentado na obra freiriana, tem-se como objetivo refletir sobre as evidências que corroboram com a relevância dos princípios da educação problematizadora para a sociedade contemporânea. O trabalho foi construído a partir de uma pesquisa qualitativa de caráter bibliográfico. Discute-se o exercício dialético-dialógico e sua correlação com as ações que possibilitem aos sujeitos a pronúncia do mundo, mundo esse que pronunciado volta-se problematizado, permitindo a geração de novas ações. Como questão problematizadora aproxima-se a temática do distanciamento social as relações educativas, o que tenciona essa possibilidade de modificação. Retoma-se que a obra de Freire está imbricada a ações que visem desvelar a realidade no intuito de promover a transformação.

Authors: Sagrilo Ana Paula Bolsan , Alencar Edvonete Souza de , Cunha Aldrin Cleyde da
Published: October 2022

Nos últimos anos o contexto educacional vem sofrendo várias transformações, principalmente, quanto à produção dos novos materiais destinados à Educação Infantil. Assim, este artigo tem por objetivo dissertar como os autores didáticos e editores dos livros do Programa Nacional do Livro e do Material Didático (PNLD) de 2019 apresentam o ensino de matemática aos docentes. Para tanto, esta é uma pesquisa qualitativa de cunho documental. Sendo que, com base no estudo realizado, foi possível inferir que o Conhecimento Especializado do Professor de Matemática (MTSK) encontra-se presente em um dos livros do PNLD produzidos para os professores da Educação Infantil. No entanto, ainda apresenta uma fragilidade quanto ao domínio MK, algo que precisa ser questionado e refletido.
Povos originários no Brasil e no México
Authors: Nascimento Sueli do , Carvalho Alonso Bezerra de , Aguirre Cynthia Coronado
Published: October 2022

Esse trabalho objetiva trabalhar diálogos entre pesquisadores para fomentar reflexões sobre a formação docente no Brasil e no México, com vistas a uma prática educativa significativa através de uma formação intercultural na qual se conectem educação e espiritualidade. Para tanto, foi realizada uma busca na literatura com temas relativos ao assunto e como a revisão do currículo embasa a formação de professores, apontando conteúdos que em sala de aula estimulam o debate tanto sobre currículo quanto sobre interculturalidade. Para tal, prevalece a opinião de que os mais indicados sejam os sujeitos habilitados numa prática educativa autorreflexiva, padrão Freire. O processo de ensino e aprendizagem intercultural deve se apoiar em pensadores e escritores latino-americanos, incluindo os saberes dos povos originários. A proposta é repensar os currículos de ambos os países, com discussões que estimulem os/as pesquisadores/as a refletir sobre a desconstrução das ideias eurocêntricas e a linearidade histórica que permeia os currículos utilizados na formação de professores.
potencialidade educativa da “Auto-organização de Mulheres Negras de Sergipe Rejane Maria”
Authors: Santos Andréia Teixeira dos , Lucini Marizete
Published: October 2022

Este texto empreende uma reflexão teórica-conceitual sobre a potência educativa da “Auto-organização de Mulheres Negras de Sergipe Rejane Maria”, criada em Aracaju-Sergipe em 2014, a partir do referencial do Feminismo Negro e da Pesquisa Ativista Feminista Negra. Nesta análise, consideramos que as mulheres negras historicamente questionam e apontam soluções com relação às desigualdades raciais, sociais, de gênero e sexualidade, organizadas em movimentos sociais. Movimentos sociais que compreendemos como espaços educativos e de formação política dos seus membros, nos quais a educação está associada a uma práxis pautada em sua insurgência propositiva. Insurgência que está associada à construção de novas epistemologias e políticas públicas que tensionam a estrutura racista, sexista, classista e heteronormativa estruturantes da sociedade brasileira. Nesse sentido, consideramos a potencialidade educativa dos trabalhos de base desenvolvidos pela “Auto-Organização de Mulheres Negras de Sergipe Rejane Maria”, como movimentos educativos em que se produzem saberes e pedagogias emancipatórios que questionam a sociedade, ao mesmo tempo em que criam estratégias educativas de combate ao racismo, classismo, sexismo e a heteronormatividade.

É um ensaio produzido em primeira pessoa, do ponto de vista de um professor formador de professores, atuando em cursos de formação docente e no mestrado e doutorado em educação, no Brasil. O objetivo principal é, na partilha da experiência, refletir sobre o sentido da docência e as dificuldades de se conseguir efetivar a renovação pedagógica presentada por Freinet, um centenário atrás.
Umbral operators for Cayley and Sylvester continuants
Authors: Munarini Emanuele
Published: October 2022

We study the main umbral operators J, M and N associated with the Cayley
continuants U(?)n(x) and the generalized Sylvester continuants H(?)n(x)
= U(?+n)n(x). In particular, we obtain their representation in terms of
the differential operator Dx and the shift operator E. Then, by using these
representations, we obtain some combinatorial and differential identities
for the continuants U(?)n(x) and H(?)n(x).

Authors: Peters Dikioye Emmanuel , Baradum Sor-Aniabari Ruth , Ohiri Reginald Chibueze
Published: October 2022

The study investigated the phytochemical and essential oil compositions of Piper umbellatum Linn leaves. The leaves were detached from the stalk and washed carefully under running tap water, air dried at room temperature (20-25 ) for 14 days. The dried leaves were ground into a fine powder using a grinding mill. Phytochemical and essential oils composition were analyzed using GC/MS. Phytochemical composition revealed higher concentrations of phenolic acids (434.95164 mg/100 g), tannin (326.79716 mg/100 g), flavonoids (263.37233 mg/100 g), and stilbenes (144.63450 mg/100 g). Essential oil composition revealed a total of forty compounds of which alpha-pinene (28.09%), beta-pinene (17.73%), beta-caryophyllene (15.21%), Nerolidol (11.72%), and Germacrene D (10.14%) were present in considerable amount. P. umbellatum Linn leaves are therefore rich in bioactive components that possess a wide range of biological activities.
DEFRAGMENTİNG STUDENTS' THİNKİNG STRUCTURE İN SOLVİNG MATHEMATİCAL ARGUMENTS
Authors: Indrawatiningsih Nonik , Lestari Andika Setyo Budi
Published: October 2022

The structure of thinking is a representation of the thought process in the form of a problem-solving flow that is carried out by a person when he resolves a problem. many students make mistakes in solving problems. One way that can be done to overcome these errors is to defragment the structure of thought. This study aims to describe the students’ erroneous thinking structure in solving mathematical argument and the defragmenting efforts. The students of 10th Grade of high school in Pasuruan, East Java, Indonesia, were involved as research subjects. They were selected based on three criteria, namely low, moderate and high level of procedural error. The activity of ‘think out loud’ was used to observe the errors made by students in solving mathematical argument. The data obtained from this activity were codified and later used as a basis to perform the defragmenting process. Based on the findings of this study, it can be concluded that procedural errors in solving mathematical argument are in the form of error in determining the value of x from an equation, modeling an argument, and proving a valid argument. Defragmenting was done using scaffolding approach to improve students' thinking structure in solving mathematical problems
