Authors: Moura Tathiany , Galvão Vivianny , Teixeira Marques Verônica
Published: December 2023

A qualidade da assistência prestada às mulheres durante o trabalho de parto é preocupação de  instituições nacionais e internacionais de saúde, que elaboraram guias para que a assistência seja prestada de forma respeitosa. Essas recomendações, porém, podem não aumentar o nível de informação das mulheres a respeito do tema. Por isso este estudo buscou analisar o entendimento de mulheres sobre violação de direitos humanos e violência obstétrica durante a assistência ao parto. Tratou-se de uma pesquisa quanti-qualitativa utilizando-se formulários e entrevistas semiestruturadas com mulheres que tiveram um ou mais filhos por via vaginal ou cesárea. A análise de dados quantitativos foi feita de forma descritiva e a qualitativa na forma de análise de conteúdo. Conclui-se que condutas consideradas como violência obstétrica e violação dos direitos humanos não são percebidas pelas mulheres como tal, pois só foi possível identificar a existência dessas condutas na análise qualitativa.

Authors: Díaz José Alejandro Sebastian Barrios
Published: December 2023

Um dos aspectos mais fundamentais da política internacional do século XXI é o processo de renovação e reconstrução da arquitetura da governança global, sobretudo com a re-emergência de países em desenvolvimento nos anos 1990 e início do século. Várias formas de intercâmbio entre países em desenvolvimento tem sido classificadas de CSS mas não há, contudo, visão consensual sobre a forma de operacionalizar a cooperação Sul-Sul. Pode-se dizer que, no caso do Brasil, predomina a CSS com caráter de cooperação técnica com foco no desenvolvimento de capacidades. O artigo tem por objetivo examinar o lugar de Moçambique na cooperação brasileira para o desenvolvimento internacional entre 2005-2020. A pergunta que orienta a análise é: qual é o espaço de Moçambique na cooperação brasileira para o desenvolvimento internacional?

Authors: Edwards S. L. , Mitchell W. , Matthews J. B. , Ingham E. , Russell S. J.
Published: December 2023

Abstract

This work is concerned with improving the design of textile scaffolds used to tissueengineer
anterior cruciate ligaments. Two important design criteria of a scaffold are
internal structure and cell-fibre compatibility. This paper considers both of these criteria,
providing a review of scaffold design and structural parameters, followed by experiments
on the biocompatibility of various generic fibres.
In this paper, the influence of surface area to volume ratio and polymer morphology on
cell-surface interactions is discussed, together with a consideration of the effect of poresize
and scaffold porosity on cell proliferation, migration and nutrient supply. Another
structural factor discussed is the role of fibre orientation as a means of guiding and
organising new tissue growth. It is possible to manipulate these scaffold parameters to
produce a scaffold of optimal structural design for the tissue engineering of the anterior
cruciate ligament.
A review of current scaffold types classified according to manufacturing method is
presented. These manufacturing methods include solvent casting/particulate leaching,
three-dimensional printing and fibre bonding. Scaffolds in fibrous form include woven,
knitted, braided, embroidered and more recently nonwoven.
Biocompatibility tests performed by the authors study the reaction of fibroblast cells to the
surface of different generic fibre types; including para-aramid, polyester, polypropylene,
polyglycolic acid and viscose rayon. The results of these tests are discussed in relation to
cell attachment and fibre morphology.

The work presented in this paper concerns an investigation we have carried out into the water retention ability of activated carbon nonwovens manufactured from cellulose fibres. The precursor nonwovens manufactured by the spun-laced method were pyrolysed and carbonised at temperatures of 400°C, 600°C, and 800°C, and next activated at the temperature of 850°C. The kinetic curves of water sorption and the absorption parameters were assessed. The proper(es of the microporous structure of the fibres were determined on the basis of the nitrogen sorption isotherm. The activated nonwovens were characterised by an active internal surface of over 1000 m2/gl. As the result of activaton, the water absorption increased by over 2.5 (mes when compared with the absorption of precursor nonwovens. The tests carried out allowed us to state that water reten(on mainly depends on the physical and the chemical properties of the carbon surface, as well as on the content of great pores in the porous structure of the fibres. In turn, the surface properties depend on the processing temperature.
STUDY OF THE BIODEGRADABILITY OF SODIUM SALT FROM THE CONDENSATION PRODUCT OF NAPHTHALENE SULPHONIC ACIDS AND FORMALDEHYDE
Authors: Ladhari N. , Hayet G. , Harrabi L.
Published: December 2023

Abstract

The biodegradability of dispersants (naphthalenesulfonate formaldehyde condensates),
used with disperse dyes, has been evaluated using different techniques such as chemical
oxygen demand (COD), UV-spectroscopic analysis and tonometry. A biomass was used
from industrial waste water which was acclimated for six months prior to use. The study
has shown that biodegradation involves two steps: first, the cleavage of the CH2 bridges;
second, the degradation of the aromatic nuclei. We identified a series of bacteria
(Pseudomonas cepacia, Pseudomonas vesicularis, Pseudomonas stutzeri,
Pseudomonas pichetti, Shevanella putrefacians, Agrobacterium radiobacter and
Aeromonas hydrophila) that proved to biodegrade the dispersant very efficiently.
THE INFLUENCE OF ACID DYES UPON SOME STRUCTURAL AND PHYSICO-MECHANICAL INDICES OF POLYAMIDE FIBRES
Authors: Nedkova Milena , Pavlov Pavel , Pishev Dimitar
Published: December 2023

The influence of three acid dyes upon some physico-mechanical indices of polyamide multifilament yarn has been studied as a consequence of the structure modifications which occur during the dyeing process. It has been established that, irrespective of the differences in the chemical composition of the dyes, the modifications in the properties of the samples used are quite similar. Some structural characteristics, tenacity and elongation at break, crease resistance and the critical time of dissolution, have been determined. The dependencies of the indices listed on the dye concentration are of a complex character, which reflects the gradual penetration of the dye molecules into the inter-fibrillar and intra-fibrillar amorphous areas of the structure which are different in solidity. The fluctuations in the course of the dependencies in the area of the lowest concentrations are the result of the combined influence of the processes of improvement of the crystal phase and the relaxation phenomena, occurring in the most accessible amorphous areas of the fibrous structure. With the increase in the dye concentration, the so-called .cross-linking effect. starts to appear, as a result of the formation of intermolecular links of the polymer-dye-polymer type, which influence the properties under investigation in a characteristic way. The increase in the dye presence in the substrate provokes the repeated alternation of the above-mentioned phenomena in the thicker amorphous areas of the samples, with a pronounced influence of the .cross-linking effect. in the highest concentrations.

Although modern sailcloth materials are extremely complex, a considerable degree of disorder is still present in the evaluation of their quality, and experience is still the most important parameter in assessing a product. For those reasons, precise characterisation and evaluation of modern sailcloth is a topic that requires systematic investigation, both in view of defining relevant characteristics & parameters, and in defining and adapting adequate testing methods and procedures & evaluation of results. The paper presented here is a contribution to the scientific and professional approach to the topic.
ON-LINE TECHNIQUE FOR MEASURING THICKNESS FOR THREE-DIMENSIONAL BRAIDED COMPOSITE MATERIAL PREFORMS
Authors: Wan Zhenkai , Li Jialu
Published: December 2023

This paper presents an automatic method that can measure the thickness of three-dimensional (3-D) braided composite preforms. The thickness of 3-D braided composite material preform is an important parameter of 3-D braided composites. With the development of 3-D braided composite technology, an automated measurement technology for thickness of braided composite preform has become an importantgoal. The objective of this paper is to present an automatic measuring system. The system we devised consisted of a computer, a proximity sensor, a pressure sensor, an analog-to-digital converter and pulse motor, etc. The measuring principle and results are discussed in the paper. The system was tested on both carbon and glass fibre preforms. We obtained very encouraging results. Experiments showed the pressure and eddy current resistance value are important parameters for measuring the thickness of 3-D braided composite material preforms. The measuring precision is higher when the pressure value ranges from 0.6kg/cm2 to 0.8kg/cm2 and the eddy current resistance is 2kΩ for preforms made of carbon-fibre than of other substances.
EFFECT OF THE SINGLE-YARN TWIST AND PLY TO SINGLE-YARN TWIST RATIO ON THE HAIRINESS AND ABRASION RESISTANCE OF COTTON TWO-PLY YARN
Authors: Palaniswamy Kolandaisamy , Mohamed Peer
Published: December 2023

Abstract

The effect of single-yarn twist and ply to single-yarn twist ratio on the evenness, hairiness
and abrasion resistance of two-ply cotton yarn has been studied. The hairiness of two-ply
yarn decreases as either the single-yarn or ply twist increases. The rate of reduction in
hairiness with respect to twist is more for the single-yarn twist than for the ply twist,
particularly for the finer two-ply yarn. Variation in hairiness decreases as the ply twist
increases. Yarn-to-yarn abrasion shows a different trend as compared to yarn-to-emery
abrasion at a low ply twist level. Two-ply yarn with 3/4 of the single-yarn twist shows the
highest abrasion resistance in both yarn-to-yarn abrasion and yarn-to-emery abrasion.
The abrasion resistance of the two-ply yarn depends on both single-yarn twist and ply
twist. Single-yarn twist and ply twist have a more influential effect on the yarn-to-yarn and
yarn-to-emery abrasion resistances respectively of cotton two-ply yarns.
ANALYSIS OF THE STABILITY OF A FLAT TEXTILE STRUCTURE
Authors: Szablewski Piotr
Published: December 2023

Abstract

This paper deals with a specific method of examining the state of equilibrium of a flat
textile structure. This kind of structure is modelled as an inextensible elastica loaded with
its dead weight and axial force. The elastica represents, as an example, a longitudinal
section of a fabric. It is assumed that the elastica rests on a flat, immovable base. We
considered only those forms of deformed elastica where it’s the two ends were supported
by pivot bearings, and the tangent at those points lay on the immovable supporting plane.
In the analysis, the shape of the deflection curve was determined for a given axial force,
and it was examined whether a given position is stable or unstable. The analysis was
carried out on the basis of the energetic method, by examining the potential energy of the
system. The investigations can be used for simulations of fabric buckling, folding and
other applications of textile mechanics.
STUDIES ON WOOLLEN THREADS FROM HISTORICAL TAPESTRIES
Authors: Odlyha Marianne , Theodorakopoulos Charis , Campana Roberto
Published: December 2023

Abstract

Fourier transform (FTIR) attenuated total reflectance (ATR) and second derivative
spectroscopy has been used for the first time to evaluate the state of degradation in
historical woollen threads from the collections of Flemish tapestries (15th-17th centuries)
in the Royal Palace, Madrid, Hampton Court Palace, and museums in Brussels. The work
was performed as part of the EC-funded project ‘Monitoring of Damage in Historic
Tapestries’, also known as the MODHT project [1]. The overall aim was to develop
procedures for recognising tapestries at risk and provide analysis for informing collection
care. Prior to the testing of the historical threads, model tapestries were prepared
according to traditional techniques of weaving and dyeing. They were then subjected to
accelerated light ageing. This paper reports on the part of the MODHT project in which
ATR-FTIR was used. It was selected since it is a non-destructive method, and also
because it has previously been used to study the oxidation products of cystine in wool
and to provide a semi-quantitative assessment of change [2]. Evaluation was conducted
on the model tapestries, and the cysteic acid peak was selected as the marker for
change, as it showed a systematic change with light ageing. The same marker was used
to assess the change in historical threads.

STRENGTH OF WET SPLICED DENIM YARNS AFTER SIZING USING A CENTRAL COMPOSITE DESIGN
Authors: Jaouachi B. , Hassen M. Ben , Sakli F.
Published: December 2023

Abstract

The retained strength of wet spliced yarns can be controlled to some extent by suitable
choices of certain factors related to the process. In order to understand how these
variables influence the breaking force of wet spliced yarns, a central composite design
was formulated and three variables - yarn count, the duration of air joining and the
duration of water joining - were considered. Analysis of the results indicates that yarn
count and length of splice contribute significantly to this mechanical property of wet sized
spliced yarns. The duration of water joining, the duration of air joining of splice and the
recipe size have a considerable effects.

carded yarn samples namely ‘Below 100mg’, ‘100-150mg’, ‘151-200mg’ and Normal sample of 50 s Ne for the
production of handloom fabrics. All the fabric samples have been produced with uniform process parameters
and their tested as per the standard procedure for durability, aesthetic characteristics, and colour fastness
properties. It is observed that the mass of kapas and its fibre properties significantly affect the fabric quality.
A NEW APPROACH TO THE UNSUPERVISED DETECTION AND CLASSIFICATION OF THE SPLICED YARN JOINT
Authors: Issa Khaled , Nagahashi Hiroshi
Published: December 2023

Abstract

This paper presents an automatic vision-based system for unsupervised detection and classification of spliced
yarn joints. In the splice detection process, a competitive learning method based on an LBG algorithm is used.
In the splice classification process, a dynamic time warping (DTW) algorithm is used to classify the extracted
splice joint into one of three categories, based on the degree of similarity between the spliced joint and the nonspliced
remaining part of the same yarn. The use of DTW in the classification makes the proposed method
adaptable to different types of yarns. Consequently, this method might be universally applicable for the
classification of all spliced yarn joints. The proposed method has been evaluated using three types of experiments,
yielding a promising result.
DEPENDENCE OF YARN AND FABRIC STRENGTH ON THE STRUCTURAL PARAMETERS
Authors: Teli M. D. , Khare A. R. , Chakrabarti Ruma
Published: December 2023

Strength of the fabric is an important property that decides and influences all other performance properties of the fabric. But though we all understand the importance of the strength of the fabric in daily wear, a systematic approach is required to correlate various strength properties with that of the yarn and fabric construction parameters. We are all aware of the effect of the individual factors like twist, count and cover factor on the strength behaviour of the fabric. However it is necessary to study the effect of all these parameters in combination with each other to ultimately influence the strength of the fabric. Such a study is also useful for designing of the fabric, depending upon the end use and the customer requirement as it is gaining importance in the recent fierce competitive scenario. In this study we have evaluated the strength properties of the fabric with respect to tensile, tear and bursting strength and correlated the results with respect to the yarn count, Twist Multiplier and picks per inch of the fabric using regression equations.
DYEING OF SULFONATION AND CROSSLINKED COTTON FABRIC
Authors: Sundrarajan M. , Gurumallesh Prabu H. , Selvam S. , Balaji R.
Published: December 2023

Abstract

Cotton fabrics were modified by different methods such as oxidation, sulfonation and crosslinking processes.
The modified and unmodified fabrics were subjected to weight measurements, water absorbency and strength
tests. In SEM analysis, modified fabrics showed improved woven pattern with less protruding fibres in x 75
magnification and swollen smooth rod like appearances in x 1500 magnification than in unmodified fabrics.
Modified fabrics were dyed with Reactive Red 120 and Direct Blue 86 under alkaline condition with low salt
content. The modified fabrics showed improved dye uptake than unmodified fabric. Crosslinking modification
was found to be very effective than sulfonation modification. Dye uptake and wet fastness properties were
improved for modified fabrics. For a 0.5% dye concentration study, the dye uptake obtained for modifications is
ranked as UM < 1W < 2W < 4W < 3W in reactive dyeing and UM < 1W < 4W <2W <3W in direct dyeing.
Evolutoids and pedaloids of frontals on timelike surfaces
Authors: Wang Yongqiao , Yang Lin , Chang Yuan , Liu Haiming
Published: December 2023

In this article, we define evolutoids and pedaloids of frontals on timelike surfaces in Minkowski 3-space. The evolutoids of frontals on timelike surfaces are not only the generalization of evolutoids of curves in the Minkowski plane but also the generalization of caustics in Minkowski 3-space. As an application of the singularity theory, we classify the singularities of evolutoids and reveal the relationships between the singularities and geometric invariants of frontals. Furthermore, we find that there exists a close connection between the pedaloids of frontals and the pedal surfaces of evolutoids. Finally, we give some examples to demonstrate the results.

Published: December 2023

In areas with high incidence of tuberculosis (TB), there are more infertile women who underwent in vitro fertilization (IVF) and have latent TB infection (LTBI), and thus, their potential risks should be paid enough attention. The purpose of our study aimed to analyze the relationship between LTBI and clinical pregnancy outcomes of IVF and fresh embryo transfer (IVF–FET). This was a retrospective study of 628 infertile women who had undergone IVF–FET in the Fourth Affiliated Hospital of Hebei Medical University from January 2019 to December 2021. The women experienced no clinical symptoms, negative imaging, and T-SPOT.TB-positive diagnosis of LTBI. We divided the study population into the LTBI group and the non-LTBI group. The clinical pregnancy rate in the LTBI group was significantly lower than that in the non-LTBI group (40.54% vs 49.51%, P = 0.031), and there was no significant difference in live birth rate and miscarriage rate between the two groups. Logistic regression analysis showed that LTBI was an independent risk factor for decreased clinical pregnancy rate in infertile women undergoing IVF–FET. In conclusion, LTBI affects clinical pregnancy rate of IVF–FET in infertile women, and therefore, clinicians (especially in countries with a high TB burden) need to pay attention to LTBI before IVF and embryo transfer.
Axisymmetric stagnation-point flow of non-Newtonian nanomaterial and heat transport over a lubricated surface: Hybrid homotopy analysis method simulations

Published: December 2023

The heat transfer phenomenon associated with the lubricated surfaces offers applications in the manufacturing processes, thermal systems, industrial systems, and engineering phenomenon. It is a well-established fact that improvement in heat transfer is recently successfully claimed with the interaction of nanoparticles. Following such motivation in mind, the prime objective of current continuation is to perform the prediction of heat transfer in second-grade material subject to the lubricated surface. The lubricants are filled with non-Newtonian power law material. The varying thickness of the thin lubricating layer permits an imperfect slip surface. The second-grade fluid interfaces with the boundary condition. The modified semi-analytical tool termed as hybrid homotopy scheme is used to perform the simulations. Shooting and homotopy methods are combined in this new approach. Relevant effects of parameters on physical phenomenon are explained. The importance of influencing parameters in relation to the velocity field, temperature, and concentration profiles is investigated graphically. It is claimed that analytical computations existed for shear thinning case. It is observed that there is a noticeable drop in concentration and thermal profiles due to the variation of viscoelastic parameter. The control of free stream velocity is claimed due to the interaction of slip parameters.

Authors: Qiu Zhengguo , Zhang Xiaqing , Jia Ni , Li Xu , Li Rui , Gopinath Subash C.B. , Jiao Mingna
Published: December 2023

Objectives

Alzheimer’s disease (AD) is an irreversible and progressive neurogenerative disorder, which affects the learning part of brain. It mainly affects the aged population and becoming a global health issue, expecting to increase more in near future. Late diagnosis of AD worsens the situation and difficult to treat the patient. Various biosensing techniques with suitable biomarkers have been developed by researchers to diagnose the earlier stages of AD.

Methods

This research was focused to develop a highly sensitive zeolite-dual probe-modified impedance biosensor for identifying AD biomarker, Aβ Oligomer (AβO). The sensing surface was initially modified with zeolite through the chemical linker and then a dual probe of anti-AβO aptamer and anti-AβO antibody were attached to the surface of the zeolite.

Results

On these dual probe-modified surfaces, AβO was quantified to diagnose AD. Further, AβO spiked artificial CSF was identified by dual probes without any interference, indicating the selective identification of AβO. In addition, control experiments with non-immune, complementary, and control proteins failed to show the increment of responses, confirming the specific detection of AβO.

Conclusions

This zeolite-dual probe-modified biosensor helps to lower the limit of detection to 0.1 pM and diagnose AD at the earlier stages.
Forward steps in green medical laboratory practices for a sustainable future
Authors: Alpdemir Medine , Yurt Emine Feyza , Şeneş Mehmet
Published: December 2023

This paper provides information on the significance of environmental sustainability and the potential benefits of implementing green laboratory processes. Sustainability is a broad concept that includes goals such as conservation of natural resources, energy efficiency, waste management, and reducing environmental footprints. Green laboratories strive to minimise environmental footprints by embedding sustainability principles into their everyday practices. This involves improvements in energy consumption, water usage, chemical waste reduction, and recycling, ultimately, as well as lower waste disposal costs. Implementing green laboratory approaches provides many benefits, such as a smaller environmental footprint, increased energy efficiency, water conservation, and cost savings. Moreover, a rational test ordering process can effectively contribute to reducing environmental impacts in medical laboratories. Rational test ordering provides cost-effectiveness and reduces the carbon footprint. Establishing a green and sustainable laboratory culture in medical laboratories requires a permanent organisation in where all personnel participate. Training of the hospital management teams, clinicians, and laboratory professionals is a vital point. Methodology and quality indicators should be defined by international and national laboratory associations within the framework of a green and sustainable laboratory plan, and data should be collected. In conclusion, adopting green laboratory practices reduces environmental impacts, saves costs, and accelerates innovation processes. Setting quality targets and rational test ordering practices are also essential for sustainability. Applying sustainability principles in laboratory workplaces is an important step towards protecting the environment and leaving a more liveable world for future generations.

Nos propomos identificar a voz das mulheres através dos documentos presentes no acervo, tendo em vista a invisibilidade verificada no período anterior à inauguração de cursos voltados à formação feminina. Parte-se da abordagem etnográfica em documentos, priorizando a coleta de dados nos arquivos, onde nos debruçamos no mapeamento e identificação das mulheres, indicadores da ação e da participação nas dinâmicas burocráticas, revelando os espaços que foram ocupados pelas mesmas desde a fundação da instituição.

O estudo da legislação permite refletir o curso histórico, percebendo o movimento das normas que regem a educação brasileira, que parecem se repetir, de tempos em tempos. Este artigo, pretende suscitar reflexões quanto aos avanços e aos retrocessos ocorridos ao longo das décadas, na formação docente para/na Educação Profissional e Tecnológica de Nível Médio (EPTNM) no Brasil. Para tanto, realizou-se uma pesquisa exploratória (MINAYO, 2009) da legislação educacional relacionada à História da Educação Profissional no Brasil, especificamente no que tange a formação de professores. Conclui-se que a formação de professores da e para a Educação Profissional, ao longo da história, tem sido alvo de políticas que não se firmam, e as idas e vindas das normas acabam comprometendo proposições duradouras no que tange a formação de professores, até os nossos dias.
Las construcciones de género y emocionalidad en las infancias a través de los textos de lectura escolar. Uruguay 1900-1930

Published: December 2023

Historizar los procesos de escolarización habilita a reconocer la producción de tramas de sentidos respecto al rol social de niños y niñas La infancia escolarizada se configuró a través de acciones políticas y educativas específicas. El manual escolar fue un dispositivo que permitió visibilizar los aspectos cívicos, políticos y de género en las representaciones de la(s) infancia(s) en la construcción de un nuevo orden social. Este artículo estudia la convergencia de discursos en estas representaciones presentes en los textos de lectura escolar. A través del estudio de los relatos e imágenes de los textos se muestra cómo se produjo un imaginario social unívoco e ideal de niños y niñas, invisibilizando otras infancias. En esta infancia imaginada se estudia específicamente la generización de los roles y el carácter performativo de los registros emocionales. Las fuentes consultadas fueron los textos de lectura escolar de las series graduadas de Figueira y de Abadie y Zarrilli autorizados por las comisiones de lectura de la Dirección General de Instrucción Primaria y las Memorias de la DGIP entre 1900-1930.
A dimensão classificatória em grupos escolares Campo-Grandenses (1958-1969)
Authors: Monteiro Hellen Caroline Valdez
Published: December 2023

objetivamos demonstrar taxas de aprovação e reprovação no Ensino Primário entre os anos de 1958 e 1969 em três Grupos Escolares na cidade de Campo Grande, atual capital do estado de Mato Grosso do Sul. Discutiremos a economia política da região, antes da divisão do estado de Mato Grosso (1977), a política educacional e as particularidades socioculturais. Para análise das fontes primárias coletadas nas instituições, quais sejam, Grupo Escolar Vespasiano Martins (1958-1961), Grupo Escolar General Malan (1962-1965) e Grupo Escolar Guia Lopes (1966-1969), nos pautamos nas discussões teóricas sobre avaliação escolar em sua dimensão classificatória. Cada instituição tinha seu modo de escrituração e apresentava especificidades na frequência dos alunos, taxa de aprovação e reprovação nos diferentes momentos históricos, demonstrando particularidades aferíveis e abrigadas na conjuntura nacional. Mediante a sistematização dos dados, buscamos trazer contribuições para a pesquisa sobre história das instituições escolares, especialmente no período de transição compreendido pela abertura tecnicista e o percentual de alunos matriculados na 1ª à 4ª série que prosseguiam ou não os estudos, dado o índice de evasão nas duas últimas séries do Ensino Primário.
Cada agora contém muitos antes e depois, cada aqui contém muitos alis: narrativas autobiográficas de professoras em perspectiva histórica

Published: December 2023

Este artigo tematiza narrativas autobiográficas de quatro professoras em exercício na rede municipal de Mantenópolis (ES), especificamente, nos anos iniciais do Ensino Fundamental, buscando dialogar com aspectos da cultura escolar inscritos nos processos históricos da educação brasileira. Analisando as trajetórias dessas professoras na História da Educação capixaba, em particular e, brasileira, de modo geral, as escolhas teórico-metodológicas permitiram pensar a educação a partir das experiências das próprias docentes, recorrendo ao resgate das suas memórias e em suas percepções enquanto sujeitos importantes no cenário educacional. Seus testemunhos de vivências e memórias no espaço escolar tornaram-se fontes para pensarmos aspectos da História da Educação capixaba e brasileira. A partir da abordagem da etnobiografia como possibilidade para a investigação com as histórias de vida de professores, apresentamos as narradoras e seus depoimentos em articulação com contextos locais, regionais e/ou globais da História da Educação.
РОЗВИТОК ЕМОЦІЙНОЇ ДЕЦЕНТРАЦІЇ ВИХОВАНЦІВ ІНКЛЮЗИВНИХ ГРУП ЗАКЛАДУ ДОШКІЛЬНОЇ ОСВІТИ ЗАСОБАМИ ІГРОТЕРАПІЇ

У статті розкривається значення ігротерапії в розвитку емоційної децентрації вихованців інклюзивних груп ЗДО. Акцентується, що емоційна децентрація, як важлива інтегральна якість особистості в дошкільному віці відтворюється у здатності розуміти почуття, думки та соціальну позицію однолітків і дорослих. Провідним завданням розвитку емоційної децентрації дітей з ООП засобами ігротерапії розглядається необхідність надання їм допомоги в самоусвідомленні, осмиленні своєї гідності, проблемних аспектів, особистих труднощів і досягнень інших людей. Доведено, що використання ігротерапії в інклюзивному освітньому просторі ЗДО сприяє н[1]лагодженню комунікації дітей з ООП з однолітками, дорослими та сприяє гармонізації їх соціальних взаємин, таким чином забезпечуючи формування в них емоційної децентрації.

OBJECTIVES

Early warning scores detecting clinical deterioration in pediatric inpatients have wide-ranging performance and use a limited number of clinical features. This study developed a machine learning model leveraging multiple static and dynamic clinical features from the electronic health record to predict the composite outcome of unplanned transfer to the ICU within 24 hours and inpatient mortality within 48 hours in hospitalized children.

METHODS

Using a retrospective development cohort of 17 630 encounters across 10 388 patients, 2 machine learning models (light gradient boosting machine [LGBM] and random forest) were trained on 542 features and compared with our institutional Pediatric Early Warning Score (I-PEWS).

RESULTS

The LGBM model significantly outperformed I-PEWS based on receiver operating characteristic curve (AUROC) for the composite outcome of ICU transfer or mortality for both internal validation and temporal validation cohorts (AUROC 0.785 95% confidence interval [0.780–0.791] vs 0.708 [0.701–0.715] for temporal validation) as well as lead-time before deterioration events (median 11 hours vs 3 hours; P = .004). However, LGBM performance as evaluated by precision recall curve was lesser in the temporal validation cohort with associated decreased positive predictive value (6% vs 29%) and increased number needed to evaluate (17 vs 3) compared with I-PEWS.

CONCLUSIONS

Our electronic health record based machine learning model demonstrated improved AUROC and lead-time in predicting clinical deterioration in pediatric inpatients 24 to 48 hours in advance compared with I-PEWS. Further work is needed to optimize model positive predictive value to allow for integration into clinical practice.

Objetivo: avaliar indicadores do programa nacional de triagem neonatal (PNTN) e de saúde no município de Rolante, RS, Brasil.
Método: estudo transversal, por meio dos prontuários eletrônicos cadastrados entre janeiro de 2017 e julho de 2020.Foi realizado o cálculo dos indicadores do PNTN dos anos de 2017 a 2019, e análise de outras variáveis de saúde como: período e local da coleta, peso e idade de nascimento, idade materna, realização de pré-natal, realização da consulta, resultado do exame e recoleta.
Resultado: a cobertura variou entre 201 de 256 (78,5%) e 229 de 272 (84,2%). Das 734 coletas 544 (74,1%) foram realizadas no período de três a cinco dias de vida, preconizado pelo Ministério da Saúde. A mediana da idade do RN na primeira consulta foi superior a 15 dias em todas as doenças triadas, exceto fenilcetonúria e deficiência de biotinidase, no período avaliado.
Conclusão: a partir dos resultados foi possível observar que a cobertura do município correspondeu aos dados nacionais e estaduais no período. E, ainda que o percentual de coletas realizadas na data ideal tenha sido alto, a idade preconizada na primeira consulta não foi cumprida na maior parte das patologias.
