O LETRAMENTO MATEMÁTICO NA EDUCAÇÃO BÁSICA SOB A ÓTICA DO PISA: UM ESTUDO EM ESCOLAS PÚBLICAS DO DISTRITO FEDERAL/BRASIL
Authors: Maria Soares de Oliveira Francisca , Elias de Sousa Nilton 
Published: June 2022

O artigo propõe analisar o processo de construção do letramento matemático na educação básica com professores do Ensino Médio de uma escola pública do Distrito Federal/Brasil a partir dos aspectos avaliados no Pisa. Para tanto, tomouse o conceito de letramento matemático, a partir do Pisa (Programa Internacional de Avaliação de Estudantes), como a capacidade individual de formular, empregar e interpretar a matemática em diferentes contextos da realidade. Essa temática foi baseada nos índices do Pisa e do Saeb que demonstraram baixa proficiência dos estudantes quanto aos conhecimentos referentes ao letramento matemático. No artigo, analisamos as justificativas para que ocorra essa baixa proficiência e os reflexos da construção do letramento matemático na mobilização desses conhecimentos para a vida. Por meio dos dados coletados, percebemos que os docentes pesquisados possuem fragilidades quanto ao Letramento Matemático, especialmente quanto às habilidades de resolução de problemas, modelagem matemática, investigação matemática e trabalho com projetos. Tais fragilidades encontram-se refletidas nos dados do Pisa e, consequentemente, do Saeb, tendo em vista os professores pesquisados não desenvolverem em suas práticas ashabilidades supracitadas. Por fim, apontou-se que o baixo índice nos resultados das avaliações do Pisa e do Saeb representam o desconhecimento dos estudantes, devido aos conhecimentos referentes ao Letramento Matemático não serem desenvolvidos em sala de aula. É urgente adentrar nesse conhecimento, proposto pela BNCC, caso se queira a elevação dos índices. Para tanto, éfundamental a articulação de saberes por meio de cursos de qualificação aos docentes, pois trata-se de um assunto de extrema importância para o desenvolvimento do conhecimento matemático.

Futures education: Curriculum and educational practices in Australia, Spain, and Chile
Authors: Castellví Jordi , Escribano Carmen , Santos Rodrigo , Marolla Jesús 
Published: June 2022

The images of the future among young people have been conditioned by the stories present in the media, films, books, and also in school. Educational curriculums are made up of a selection of knowledge that privileges some ways of understanding the future over others. Young people often imagine a future that is in economic, social, and/or climate crisis. However, they also imagine a bright future for themselves, detached from the future they imagine for society. In this article, we present a qualitative analysis of the curriculums of Australia, Spain, and Chile, together with interviews with teachers from these countries. We investigate the presence and absence of futures education in these curriculums, their degree of development regarding futures education, and make a first analysis of the influence of futures education in schools. To do this we identify four dimensions: situate in time, anticipate, imagine alternative futures, and social action. The results show that, while the Australian curriculum explicitly includes education for the future, the Spanish and Chilean curriculum include it only tangentially. In addition, the socio-cultural context of schools and the will of the teaching staff are elements that determine the implementation of futures education in the school context.
Diversos estudios nos indican que las imágenes del futuro que tienen los jóvenes están condicionadas por los relatos presentes en los medios de comunicación, las películas, los libros y también en la escuela. Los currículos educativos incluyen una selección de contenidos que privilegian unas formas de entender el futuro por encima de otras. Los jóvenes suelen representar un futuro en crisis económica, social y/o climática. Sin embargo, estos imaginan para sí mismos un futuro brillante, totalmente desligado del futuro de la sociedad. En este artículo presentamos un análisis cualitativo de carácter descriptivo e interpretativo de los currículos de Australia, España y Chile, junto con entrevistas a docentes de estos países, para estudiar la presencia y ausencia de la educación para el futuro en sus planes de estudios, así como su grado de desarrollo, y hacer un primer análisis de la influencia de la educación para el futuro en las escuelas. Para ello identificamos cuatro dimensiones: situar en el tiempo, anticipar, imaginar futuros alternativos y actuar socialmente. Los resultados muestran que, mientras que el currículo australiano incluye de forma explícita la educación para el futuro, el currículo español y chileno la incluyen solo de forma tangencial. Además, el contexto sociocultural del centro y la voluntad del profesorado son elementos que determinan el desarrollo de la educación para el futuro en la escuela.

Authors: Hejaz Hatem A. , Nawajah Inad , Wredat Maaly , Melhem Walaa 
Published: June 2022

Background:
Coronavirus disease-2019 (COVID-19) outbreak is a global concern and the World Health Organization (WHO) has declared it as a public health emergency of international concern.

Objectives:
This study aimed to assess knowledge, attitude, and practices (KAP) toward COVID-19 among the general population of Palestine at the time of the COVID-19 pandemic.

Materials and Methods:
A cross-sectional study was conducted using an online questionnaire; a series of questions regarding the KAP of the population about COVID-19 was asked, and participants’ demographic characteristics and source of information regarding COVID-19 were collected and analyzed using Statistical Package for the Social Sciences (SPSS) software program, version 26.0.

Results:
Seven hundred twenty-four individuals participated in this study. The average age of the participants was 28 years (standard deviation [SD] = 10.7), the majority were females 558 (77.1%), with a bachelor’s degree 480 (66.3%), and 229 (31.6%) students. Most of them from Hebron governorate 609 (84.1%) and many of them reported that they wear a mask when they leave their house and avoid shaking hands, 494 (68.2%), 424 (58.6%), respectively. The results indicate that Palestinians have a good level of knowledge about COVID-19 with a positive attitude and good compliance with Palestinian government measures. The result showed a significant correlation between female gender, higher age, and higher education with KAP. However, male gender, nonhealth-care-related professions, single, and lower level of education were significantly associated with lower knowledge scores. There was no clear satisfaction with the government’s role in limiting and controlling the spread of COVID-19.

Conclusions:
Palestinian population showed decent knowledge, appropriate practice, and a positive attitude toward the COVID-19 outbreak.
Expression of tissue PSA in breast cancer is associated with less aggressive disease and lower chance of tumor relapse
Authors: Hachim Ibrahim Yaseen , Hachim Mahmood Yaseen , López-Ozuna Vanessa Michel , Al-Hadithi Raji H. M. 
Published: June 2022

Background:
Human kallikrein 3 (hK3), also known as Prostatic specific antigen (PSA), was considered as one of the most useful markers for the detection as well as management of prostate cancer. While PSA was thought to be a prostatic tissue-specific protein, many reports suggest the presence of extraprostatic PSA in different tissues, including the breast. Few reports showed PSA immunoreactivity in breast cancer tissues and suggest a favorable prognostic role of PSA in breast cancer. However, most of those studies were not conclusive or restricted to small scale studies limiting their clinical significance.

Methods:
We used a bioinformatical approach to investigate the association between tissue PSA expression levels and different clinicopathological parameters in breast cancer using different publicly available databases. Further validation was done using our patient cohort of 40 surgical breast samples obtained from patients attending Al Kadhemyia Teaching Hospital – Iraq.

Results:
Using a cohort of 593 breast lesion samples extracted from the TCGA database using the ONCOMINE database, our results showed no significant upregulation of PSA mRNA levels in breast cancer samples compared to healthy tissue (P = 0.1). The same trend was also observed in our patient cohort with positive immunoreactivity in 50% (5 samples) of benign lesions compared to 36.66% (11 samples) in breast cancer samples. In addition, investigating the correlation between mRNA PSA expression and different clinicopathological parameters using the Breast Cancer Gene-Expression Miner v4.0 database and ONCOMINE databases, revealed a significant association between PSA expression and tumor grade (P = 0.0001), breast cancer subtype (P < 0.0001), in addition to early-stage disease presented as smaller tumor size and absence of LN involvement. The same trend confirmed with our patient cohort. Moreover, our analysis using KM plotter (4000 breast cancer samples) showed a significant association between higher PSA mRNA levels and favorable patient outcomes presented as prolonged relapse-free survival (RFS) (P < 0.0001).

Conclusions:
Our results clearly demonstrate the possibility of using tissue mRNA and protein levels of PSA as a marker to identify patients with a favorable outcome and lower risk of tumor recurrence. Our results also highlight the need for more efforts to investigate the biological role of PSA in breast cancer.
Comparing Different Doses of Dexmedetomidine Combined with Ropivacaine for Ultrasound-Guided Supraclavicular Brachial Plexus Block in Upper Limb Surgeries - A Prospective Randomized Controlled Trial
Authors: Akshara P. , Govindan Dilip Kumar , Govindasamy Jagan , Arif Mohamed , Sethuraman Raghuraman M. 
Published: June 2022

Background:
Dexmedetomidine is used as an adjuvant to local anesthetic agents to provide prolonged analgesia in peripheral nerve blocks. This study aimed at determining the optimal dose of dexmedetomidine, which when combined with ropivacaine will produce a superior quality block in terms of extended pain-free period and reduced perioperative analgesic/opioid use, which in turn improves patient satisfaction.

Objective:
The objective of the study is to assess the duration of analgesia with two different doses (25 μg and 50 μg) of dexmedetomidine with ropivacaine in supraclavicular brachial plexus block.

Subjects and Methods:
This prospective randomized controlled study included 50 patients undergoing upper limb surgeries under supraclavicular brachial plexus block randomly divided into two groups. Group D25 received 29 mL of 0.5% ropivacaine +25 μg dexmedetomidine diluted in 1 mL of normal saline (total 30 mL); Group D50 received 29 mL of 0.5% ropivacaine +50 μg dexmedetomidine diluted in 1 mL of normal saline (total 30 mL). Onset and duration of sensorimotor block, duration of analgesia, and time interval for the rescue analgesia and hemodynamic stability were observed.

Results:
The mean onset of motor and sensory block was significantly higher in the D25 group (P = 0.001). The Visual Analog Scale pain scores and rescue analgesia consumption were significantly lower in the D50 group (P = 0.013, 0.001). The duration of analgesia was significantly higher in the D50 group (P = 0.001).

Conclusion:
Dexmedetomidine 50 μg is an effective adjuvant dose to ropivacaine with insignificant hemodynamic changes with better duration of analgesia and lesser pain scores.
Perioperative Adverse Respiratory Events in Children with Obstructive Sleep Apnoea
Authors: Thampi Swapna , Chong Shang Yee , Pawar Dilip Kumar 
Published: June 2022

Background:
Obstructive sleep apnoea (OSA) in children is associated with the development of perioperative adverse respiratory events. The aim of our study was to find out the incidence of perioperative adverse respiratory events, to identify the risk predictors and to determine the appropriate anaesthetic agents in children with OSA.

Methods
After obtaining approval from the the Institutional Review Board, 189 children with OSA who had undergone adenotonsillectomy between 2004 and 2009 were selected from a retrospective review of case files. Variables recorded included demographic data, coexistent medical illnesses, anaesthetic techniques (including induction agents and muscle relaxants) and perioperative analgesia. The severity of OSA was determined based on polysomnographic criteria. Adverse events including difficult airway, desaturation due to bronchospasm or laryngospasm, postoperative desaturation and unplanned intensive care unit (ICU) admission occurring up to 24 h postoperatively were recorded.

Results
The incidence of perioperative respiratory adverse events was 19.6%. Severe OSA (odds ratio [OR] 5.8; 95% confidence interval [CI] 1.8–18.53; P = 0.003) and moderate OSA (OR 3.9; 95% CI 1.1–13.1; P = 0.029) were independent risk factors associated with complications. There was no correlation between the intraoperative anaesthetic techniques or use of perioperative opioid analgesics and the perioperative adverse respiratory events.

Conclusions
Preoperative diagnosis of OSA using polysomnography has been shown to identify children who are at increased risk of perioperative adverse respiratory events in children. In our review, 19.6% of children with OSA were at risk. The use of a severity index may better identify children at higher risk.
Use artificial neural network to recommend the lumbar spinal endoscopic surgical corridor
Authors: Chen Chien-Min , Chen Pei-Chen , Chen Ying-Chieh , Wang Guan-Chyuan 
Published: June 2022

Objectives:
The transforaminal and interlaminar approaches are the two main surgical corridors of full endoscopic lumbar surgery. However, there are no quantifying methods for assessing the best surgical approach for each patient. This study aimed to establish an artificial intelligence (AI) model using an artificial neural network (ANN).

Materials and Methods:
Patients who underwent full endoscopic lumbar spinal surgery were enrolled in this research. Fourteen pre-operative factors were fed into the ANN. A three-layer deep neural network was constructed. Patient data were divided into the training, validation, and testing datasets.

Results:
There were 899 patients enrolled. The accuracy of the training, validation, and test datasets were 87.3%, 85.5%, and 85.0%, respectively. The positive predictive values for the transforaminal and interlaminar approaches were 85.1% and 89.1%, respectively. The area under the curve of the receiver operating characteristic was 0.91. The SHapley Additive exPlanations algorithm was utilized to explain the relative importance of each factor. The surgical lumbar level was the most important factor, followed by herniated disc localization and migrating disc zone level.

Conclusion:
ANN can effectively learn from the choice of an experienced spinal endoscopic surgeon and can accurately predict the appropriate surgical approach.
Zeros in the character tables of symmetric groups with an -core index
Authors: McSpirit Eleanor , Ono Ken 
Published: June 2022

AbstractLet
$\mathcal {C}_n =\left [\chi _{\lambda }(\mu )\right ]_{\lambda , \mu }$
be the character table for
$S_n,$
where the indices
$\lambda $
and
$\mu $
run over the
$p(n)$
many integer partitions of
$n.$
In this note, we study
$Z_{\ell }(n),$
the number of zero entries
$\chi _{\lambda }(\mu )$
in
$\mathcal {C}_n,$
where
$\lambda $
is an
$\ell $
-core partition of
$n.$
For every prime
$\ell \geq 5,$
we prove an asymptotic formula of the form
$$ \begin{align*}Z_{\ell}(n)\sim \alpha_{\ell}\cdot \sigma_{\ell}(n+\delta_{\ell})p(n)\gg_{\ell} n^{\frac{\ell-5}{2}}e^{\pi\sqrt{2n/3}}, \end{align*} $$
where
$\sigma _{\ell }(n)$
is a twisted Legendre symbol divisor function,
$\delta _{\ell }:=(\ell ^2-1)/24,$
and
$1/\alpha _{\ell }>0$
is a normalization of the Dirichlet L-value
$L\left (\left ( \frac {\cdot }{\ell } \right ),\frac {\ell -1}{2}\right ).$
For primes
$\ell $
and
$n>\ell ^6/24,$
we show that
$\chi _{\lambda }(\mu )=0$
whenever
$\lambda $
and
$\mu $
are both
$\ell $
-cores. Furthermore, if
$Z^*_{\ell }(n)$
is the number of zero entries indexed by two
$\ell $
-cores, then, for
$\ell \geq 5$
, we obtain the asymptotic
$$ \begin{align*}Z^*_{\ell}(n)\sim \alpha_{\ell}^2 \cdot \sigma_{\ell}( n+\delta_{\ell})^2 \gg_{\ell} n^{\ell-3}. \end{align*} $$
