When your ankle becomes a knee - a clinical study on long-term functional outcome and quality of life with a rotationplasty after resection of malignant limb tumors
Authors:   , Gotta Jennifer
Published: January 2023

Background: Increasing numbers of patients surviving malignant bone tumors around the knee joint have led to an increasing importance to investigate long-term results. This study assessed the long-term results of rotationplasty after resection of malignant bone tumors regarding functional outcome and quality of life to allow better comparison with other treatment options in bone cancer treatment. Procedure: 60 participants who underwent rotationplasty due to bone cancer took part in this multicentric questionnaire- based study. The long-term functional outcome was measured by the Musculoskeletal tumor society score (MSTS) and the Tegner activity level scale. The health-related quality of life (HRQL) was assessed by using the Short Form Health Survey (SF-36). Results: Patients treated with rotationplasty (median follow- up of 22 years, range 10–47 years) regained a high level of activity (median MSTS score of 24). Even a return to high level sports was possible (mean Tegner activity level scale of 4). Duration of follow-up did not influence the functional outcome. HRQL scores were comparable to the general German popula tion. Concerns of psychological problems due to the unusual appearance of the rotated foot have not been confirmed. Conclusion: Rotationplasty can be a good alternative to en- doprosthetic replacement or amputation, either as primary surgery or as a salvage procedure. Especially for growing children and very active patients rotationplasty should be considered.

Published: January 2023

A developed methodology for evaluating measurement uncertainty during the tensile tests of metals and alloys is presented. In this connection, the various sources of uncertainty are considered. The object of studies included high-strength bolts made of 40Kh “Selekt” steel, which were subjected to tensile tests according to the GOST 1497-85 State Standard using a UMM-100 universal tensile testing machine. The basic sources of uncertainty in the measurement of relative elongation and reduction were shown to include repeated measurements of relative elongation; errors of measuring the finite length by a vernier calliper and marking the initial length of a calculated section, as well as the measurement error of the tensile testing machine. These also include operator reading error, repeated relative reduction measurements, as well as the error of measuring the sample diameter by a micrometer before and after the tests. During the measurements, temperature deviation was demonstrated to constitute an additional source of uncertainty when the ambient temperature is different from the standard temperature value ((20±5)°C). Assumptions underlying laws describing the distribution of input values were assigned. Tensile tests are shown to be characterised by two components of uncertainty evaluated as types A and B. A mathematical model constructed for measuring relative elongation and relative reduction during tensile tests is presented. The standard uncertainties of input values are evaluated based on the assumed laws of their distribution. A correlation between the final length of the calculated section, the diameter of the sample following the test, and the applied force, is revealed. Expressions for the calculation of sensitivity coefficients, which characterize variations in the output value (relative elongation) depending on variations of input values, were obtained. The total and extended measurement uncertainties were evaluated. Based on the performed studies, a procedure for evaluating measurement uncertainty when carrying out tensile tests of high-strength bolts was described. The evaluation of measurement uncertainty during the product testing was shown to be a rather labourconsuming work. In this regard, the authors propose the development of procedures for evaluating the measurement uncertainty during the tests with their inclusion into regulatory documents for control methods.
Impact of distributed energy generation on energy supply to consumers in an integrated energy system
Authors: Barakhtenko E. A. , Mayorov G. S.
Published: January 2023

In this work, an approach for accounting and regulating the share of distributed generation in an integrated energy system is developed. In order to model an integrated energy system, a multi-agent approach was used, which presents a technologically complex system as a combination of agents, each having individual behaviour. The essence of a multi-agent approach is as follows: an integrated energy system is represented as a combination of components modelled by their agents having an individual behaviour algorithm; each element of an integrated energy system is involved in the generation of a solution and protects its interests on the basis of efficient energy supply. The implementation of this approach was carried out using the AnyLogic software environment, which includes the basic components of agent and simulation modelling, allowing any multi-agent systems to be developed depending on the application. The custom structure of the multi-agent system for integrated energy systems was developed, factoring in its performance features and interaction of objects, the main composition and types of agents of the multi-agent system being determined. The following types of agents were distinguished: consumer agent, dynamic consumer agent, network agent, manager agent of dynamic consumer, agent of centralised energy source, network agent and advisory agent. A multi - agent model of a real power supply system of a residential area in Irkutsk, having centralised and distributed energy sources, was developed. Taking into account the efficient operation of centralised energy sources, the principles for regulating the share of distributed generation in the system were proposed, allowing the total costs of energy supply to consumers to be reduced by rearranging power between centralised and distributed generation sources. The results obtained using the developed multi-agent model were used to formulate the principles of interactions of centralised and distributed energy generation sources. The redistribution of power between these energy sources on the basis of the above principles reduced the total costs by 4.22% for heat supply and 9.94% for electricity supply to consumers.
Steady-state equation of thermal explosion in a distributed activation energy medium: numerical solution and approximations
Authors: Donskoy I. G.
Published: January 2023

This work presents a mathematical model of thermal explosion in a medium described by a Gaussian distribution of reactivity, along with the determination of critical values for model parameters and their dependence on the distribution dispersion. The numerical solution of boundary value problems for steady-state temperature distribution in a reaction medium (a sweep method along with the iterative refinement of a source function, a half-interval method to find the critical value of the Frank-Kamenetskii parameter) was used. The grid convergence was investigated for the used difference scheme; the first order of accuracy was observed as a result of numerical evaluation of the critical value of the Frank-Kamenetskii parameter. Calculations were carried out with accuracy to three decimal places. Numerical methods were implemented as programs in the MATLAB environment. Numerical approximations were obtained for solutions of the thermal explosion equation characterised by distributed activation energy in the quasi-steady-state approximation. It was shown that the critical value of the Frank-Kamenetskii parameter is associated with the dispersion of the distribution and the Arrhenius parameter by a simple approximate analytical formula, confirmed by comparing with numerical estimates. Since the dependence of the critical value of the Frank-Kamenetskii parameter on the dispersion is described by a Gaussian function, the reaction medium becomes thermally unstable even at small values of the distribution dispersion. Calculations showed that a significant dispersion of reactivity (on the order of tenths of the average) can be observed only for chemical reactions characterised by low sensitivity to temperature (i.e. a small heat effect or low activation energy). Approximate formulas for critical conditions were also obtained for asymmetrical distribution functions. The analysis allows the proposed mathematical model to be used for assessing the thermal stability of reactive media having distributed reactivity (for example, natural materials, polymers, heterogeneous catalytic systems, etc.).
Mathematical modeling of zinc concentrate roasting in a fluidized bed
Authors: Alkatsev V. M. , Rutkovsky A. L. , Makoeva A. K.
Published: January 2023

The paper aims to stabilize the roasting of zinc sulfide concentrates in fluidized-bed furnaces using oxygen- enriched air. The balance between the given excess air blast (on average 20%) and the amount of loaded charge is achieved by selecting an appropriate number of evaporative cooling elements in the fluidized-bed furnace. Through the evaluation of scientific and technical information, as well as literature sources on the research topic, data were collected on the effects produced by an oxygen excess in the blast on the quality of sulfide concentrate roasting and by a blast volume on the state of the fluidized bed. In addition, statistical data for the study were obtained by analyzing the operation of fluidized-bed furnaces at Electrozinc. As part of the study, the heat balance in roasting was determined, taking into account the following technical characteristics of fluidized-bed furnaces used for roasting zinc sulfide concentrates: fluidized- bed level, number of nozzles, furnace diameter, diameter in the bed zone, hearth thickness, and the total weight of the furnace. Relying on the operation analysis of fluidized-bed furnaces, a method was proposed to regulate the oxygen supply depending on the amount of loaded charge. The oxygen supply is regulated in order to ensure a stable excess of oxygen in the blast without causing any significant changes in the blast volume and, consequently, to maximize the sulfur removal from the charge. A decrease in the excess air blast below 15% was found to significantly degrade the quality of the resulting cinder and dust, while an increase of over 20% reduced the SO2 content in the exhaust gases with no noticeable improvement in the quality of cinder. Therefore, the proposed method for regulating the oxygen supply to the furnace can improve the techno-economic performance of zinc sulfide concentrate roasting in fluidized-bed furnaces.
Selection of a leaching system for the extraction of gold from the ore of the Byn’govskoye deposit
Authors: Lobanov V. G. , Khabibulina R. E. , Kolmachikhina O. B. , Makovskaia O. Yu.
Published: January 2023

A theoretical substantiation of an environmentally friendly technology for extracting gold from mineral raw materials is presented. In terms of an alternative to conventional cyanide, the authors propose chlorine-bearing derivatives of organic isocyanuric acid (C3H3N3O3). In the studied process, this reagent combines the roles of a long-acting oxidant and complexing agent due to the resulting Cl– ion. For experimental purposes, the rotating disc technique was applied. Experimental results were evaluated by measuring the concentration of gold in solutions using the atomic adsorption method. The theoretical characteristics of gold dissolution using the proposed reagent were studied. In order to evaluate the applicability of the revealed regularities for practical purposes, comparative indicators for leaching gold from the ore of the Byn’govskoye deposit (Sverdlovsk Oblast) using the proposed reagent, cyanide and CYCAD cyanide substitute (China) were evaluated. The dependence of the gold disc dissolution rate on temperature, as well as leaching reagent and hydrochloric acid concentrations, were studied. In disc sample experiments, the exponential dependence of the dissolution rate on the concentration of the studied reagent was established. In this case, the maximum intensity of the process is achieved at a concentration higher than 50 g/dm3. The optimum acidity level comprises 0.3–0.4 g ion/dm3 of hydrochloric acid. Despite an increase in temperature being shown to accelerate the dissolution process, this appears to be technologically unjustified. Under optimal conditions, the gold disc dissolution rate reaches 0.5•10-3 g ion/(cm2•min), which is approximately one hundred times higher than during the dissolution by the cyanic solutions in conventional modes. Close gold extraction values were achieved in the solutions of cyanides and chlorine-bearing derivatives of isocyanuric acid during the leaching of gold from the ore under the comparable conditions. For CYCAD solutions, the same indicator is two times lower. The results of the performed studies demonstrate the high dissolution rate of gold using the proposed reagent along with the technological possibility of leaching gold from ores using this environmentally friendly reagent.

Published: January 2023

A hydrometallurgical technology has been proposed for processing the refractory part of the lining of aluminum production electrolysers dismantled and disabled for overhaul. Fluorine-containing compounds are transferred to the solution, which allows obtaining cryolite for being used in the electrolysis process. It is recommended to use solid residue from leaching (cake) with a minimum content of alkalis and fluorine as an additive to the mixture for cement production. According to the results of experiments on obtaining portland cement by traditional firing technology, the limiting content of alkali metal oxides (not higher than 4.5% by weight, calculated as Na2O) in the leaching cake was determined, the optimum content of this additive in the charge is from 5 to 12% depending on chemical composition of lime used.

Published: January 2023

This paper examines the kinetics of corrosion for steel St3 samples covered with a latex coating 69B–2k, manufactured by Kapitel LLC (Irkutsk), by analysing gravimetric tests performed using steel samples. A 3 wt % solution of sodium chloride was used as an electrolyte. The accuracy of the obtained results was confirmed by carrying out at least two parallel experiments. Prior to coating, the metal surface of samples was carefully prepared as per GOST R 9.907-2007. Film coatings were applied onto the metal surface by threefold dipping of samples in liquid latex followed by drying within 24 hours. The quality of the coating prior to and following the experiments was assessed visually and by microphotography. Gravimetric studies were carried out under temperature control (25 ± 0.2°C) in the working area. At the same time, changes in the sample mass were recorded over a controlled time interval (from 1 to 24 hours). The results of weighing samples obtained prior to and following the experiments were analysed using a kinetic flowchart, in which the type of reaction is defined in stages in a natural sequence. Kinetic analysis of the gravimetric results confirmed the absence of characteristic signs associated with chemical interactions on the surface of steel St3 coated with latex 69B-2k. Out of the known mathematical models of phenomenological kinetics, it is admissible to use a first-order equation to describe the course of a simple reaction during heterogeneous interaction, where the penetration of reagents through a latex film comprises a limiting stage. The kinetic analysis showed that it is necessary to study the properties of latex films; a strategy for further corrosion studies was determined.
Academic and Public Reputation of Universities: Priorities, Methods, and Management Tools
Authors: Abaev A. L. , Golova A. G.
Published: January 2023

The article is dedicated to the modern content of university reputation. It reveals the correlation of the concepts of reputation and image, and provides on overview of main factors influencing the reputation of universities. Within the study, the authors rely on the approaches of international rating agencies to determine the academic reputation of universities and the methodology for determining the indicators of ranking universities. The authors proceed from the assumption that the transformation processes taking place in the field of education show that academic reputation alone is no longer enough to attract applicants and representatives of other interested groups. Based on the results of the study, the article proposes the use of the concept of public (or social) reputation, as is customary in the business environment. At the same time, the authors distinguish “traditional” and digital contours of reputation. They note that the specificity of the educational sphere is determined by its diversity and multivector nature of the results of the activities of educational institutions, which determines the specifics of the use of communication tools in the formation and preservation of the public reputation of universities.

Authors: Bottaini Carlo , Vilaça Raquel , Osório Marcos , Montero Ruiz Ignacio , Mack Pietro
Published: January 2023

This paper focuses on the study of a group of metal artefacts recently recovered during the archaeological excavations in Vila do Touro (Central Portugal), i.e., 19 artefacts and a small metallic inclusion embedded in a pottery sherd. The objects have been analysed by an X-Ray Fluorescence spectrometer to characterise the elemental composition of metal artefacts. A Scanning Electron Microscope with X-ray Microanalysis System and an optical microscope were used to observe and chemically characterise the metal inclusion in the pottery. The fragment of an ingot was also analysed by a multicollector Inductively coupled plasma mass spectrometer to address issues bound to the provenance of raw material. The results revealed different compositional patterns (pure copper, binary bronze, i.e., Cu+Sn, leaded bronzes, i.e., Cu+Sn+Pb, and gold), while pointing out the Ossa Morena region (Southwest of the Iberian Peninsula) as likely source of copper used to produce the ingot.
Nihilismo y acidia: el sin sentido del carácter contemporáneo
Authors: Cuevas Thais
Published: January 2023

En el presente artículo se expondrá la correspondencia que yace entre el concepto nihilista, que se da desde la filosofía de Nietzsche; y la acidia, como parte del desarrollo de los pecados capitales que manifiesta Tomás de Aquino. Relación que, aun teniendo en cuenta la amplia diferencia de época de los autores, se deja entrever cómo ambos visualizan en el hombre una serie de conductas que trascienden a todo su entendimiento espiritual y psicológico, vislumbrando el «sin sentido» como punto final de toda acción humana que cae en aquellas disyuntivas. Entendiendo entonces el hecho de que Tomás de Aquino y Nietzsche sean capaces de dilucidar en la sociedad una pérdida de valores y hábitos, es posible percatar los matices que exponen al hombre como víctima y victimario de su propio destino adherido a aquellas nociones antropológicas.

Authors: Bernaards Coen A. , Fischer Kathrin I. , Rylands Angela J. , Gater Adam , Tolley Chloe , Zarit Steven H. , Lansdall Claire J.
Published: January 2023

Background:

Caring for an individual with Alzheimer’s disease (AD) is an allencompassing
challenge that affects daily life. Assessment of the care partner experience is needed to
support the development and evaluation of successful interventions for people with AD and their care
partners. We developed the 27-item Zarit Caregiver Interview for Alzheimer’s Disease (ZCI-AD-27)
to assess the impact of informal caregiving in the context of AD.

Objective:

We assessed the psychometric validity of the ZCI-AD-27 in a population of care partners
for individuals with moderate AD, and established thresholds for meaningful score change.

Methods:

Secondary data were obtained from informal care partners of participants in a clinical trial
(NCT01677754). Psychometric analyses were conducted to assess validity, reliability, and responsiveness
of the ZCI-AD-27. Anchor-based and distribution-based methods were performed to determine
clinically meaningful score change.

Results:

The ZCI-AD-27 had a 12-domain factor structure, including a second-order domain termed
Humanistic impact that included four key domains (Physical, Emotional, Social, and Daily life) as
confirmed by confirmatory factor analysis with the adequate fit. Internal consistency (Cronbach’s alpha
ranging from 0.66 to 0.93 for domains), convergent validity, and discriminant validity indicated
the good performance of the ZCI-AD-27. Known-groups validity analyses showed a greater impact on
care partners with increasing disease severity. Responsiveness results demonstrated that the ZCI-AD-
27 is sensitive to change over time and meaningful change analyses indicated a range of meaningful
score changes in this population.

Conclusion:

The ZCI-AD-27 is a comprehensive, psychometrically valid measure to assess the impact
of caring for individuals with moderate AD.
Bioactive Heterocycles: Green Synthesis and its Anti-Alzheimer Activity
Authors: Fathima Afridha Mohamed Sulthan Hasan , Aazath Kathar , Roopan Selvaraj Mohana , Anto Simplica Sagayaraj Jane
Published: January 2023

The wide pharmaceutical activity of the bioactive heterocycles, which include nitrogen,
oxygen, and sulphur and comprise five- and six-membered rings, has drawn the attention of medicinal
chemists for several years. The therapeutic potential of bioactive heterocycles for a variety of disorders
lies in their medicinal effects. The most prominent of them is Alzheimer's disease (AD), a
neurodegenerative disorder that impairs memory and causes other psychiatric problems. Globally, there
are around 54 million cases, and by 2050, that number is predicted to rise by 131 million. So far,
donepezil, galantamine, and rivastigmine have indeed received FDA approval for use in the treatment of
AD. In this regard, the pharmacophoric properties of heterocycle molecules are equivalent to those of
galantamine mimics. Therefore, it is beneficial to create novel compounds containing these moieties and
test their ability to inhibit acetyl and butyl cholinesterase. Diverse heterocyclic scaffolds may now have
therapeutic potential for Alzheimer's disease. Recently, greener and more expeditious synthesis of
bioactive heterocycles has drawn much attention because of the utilisation of environmentally benign
protocols, thereby diminishing the usage of hazardous chemicals. In this review, we discuss the most
pertinent findings about the "green" synthesis of heterocycles and their possible anti-activity against
Alzheimer's.

Manufactured by Laser Additive Manufacturing
Authors: Huang Lei , Chen Xizhang , Konovalov Sergey , Su Chuanchu , Pan Xiaoming , Panchenko Irina
Published: January 2023

Background:

Laser additive manufacturing has been used for surface repair and remanufacturing
due to fast laser processing speed, high energy density, and dense microstructure.
However, the properties of coating samples produced by laser additive manufacturing of ironbased
alloys vary considerably, resulting in a large amount of data that needs to be accumulated
and analyzed.

Methods:

The coating properties of iron-based alloy powders manufactured by laser cladding are
studied. The optimal process parameters of the laser cladding are determined by exploring and
comparing the macroscopic appearance, hardness, and conductivity of the junction of the cladding.

Results:

From the macroscopic appearance, when the ratio of the height to the width of the cladding
layer is 3.615, the surface of the cladding layer has a smooth surface and is closely combined
with the substrate.

Conclusions:

The hardness of the cladding layer is found to increase significantly, with an average
hardness of 663 HV. Besides, it is found that the blackhead's hole causes the conductivity
change. The ratio of the largest hole area to the smallest hole area is 8.29 times, and the depth ratio
is 1.91 times, but the average resistance ratio is about 1.6 times.

The integrated service post program (in Indonesian: posyandu) aims to reduce infant mortality, and maternal mortality rates. However, the coverage of posyandu visits in Singosari sub-district was low (<50%) in 2021; hence this study aims to identify enabling and reinforcing factors of the behavior of posyandu visits. This research was conducted in Banjarum Village on 61 mothers who have toddlers. The survey instrument was used to identify factors related to the behaviour of visiting the posyandu under five. The results of the enabling factors showed that 88.52% of mothers had a health card, 93.44% of mothers said their children did not receive immunisation at the posyandu for during the last three months, and 100% of mothers added that the posyandu had a supplementary food provision program. The results of the enabling factors show that 100% of mothers have the support of family and community leaders to bring their toddlers to visit the posyandu, and say they need a posyandu in their residence. There was no significant relationship between enabling factors and the behaviour of mothers who brought their children to the posyandu under five (p ³ 0.05). This study includes a small number of respondents and was conducted during the COVID-19 pandemic, therefore further research can be carried out on a larger sample size and during periods outside the pandemic.

Como ser um bom aluno? Dos modelos de escola aos pontos de vista das crianças
Authors: Melo Benedita
Published: January 2023

Resumo 
A apologia da performatividade e da excelência, resultante dos novos modos de regulação dos sistemas educativos, parece estar a penetrar em todos os níveis de escolaridade. Centrado na análise do ofício de aluno do 1.º ciclo, e tendo por base a hipótese de que estará em curso uma reconfiguração do modelo da escola primária assente na performatividade-competitividade, este texto analisa as perspetivas que crianças, oriundas de contextos geográficos, escolares e socioeconómicos distintos, possuem sobre o que é ser um bom aluno. A pesquisa teve por base a análise de conteúdo de entrevistas semidiretivas realizadas a 61 crianças do 3.º ano de escolaridade, em 2017/18. Os pontos de vista das crianças evidenciam duas dimensões essenciais das práticas escolares: a dimensão do poder e a dimensão cognitiva. As suas referências à ordem escolar deixam perceber como a estrutura do modelo de escola tradicional-industrial subsiste na atualidade. No entanto, é a componente das aprendizagens a que é mais valorizada nos seus discursos. As condições por elas enunciadas para participarem nos processos de aprendizagem dão conta de dois tipos de conceções sobre a excelência escolar. Uma primeira que enaltece os dons individuais, nomeadamente a inteligência, presente sobretudo entre as crianças com uma proveniência social menos escolarizada e menor desempenho escolar. Uma segunda conceção, próxima do modelo escolar performativo-competitivo, surge ancorada no trabalho, esforço, dedicação e superação individual, e está sobretudo presente nas crianças oriundas de famílias mais escolarizadas, com muito bom aproveitamento escolar.

Estratégias para promover a agência do estudante no processo de avaliação e feedback digital
Authors: Casanova Diogo
Published: January 2023

A avaliação e o feedback digital têm vindo a crescer como temas de investigação nos últimos anos, em particular no ensino superior. Dentro destes temas, o papel do estudante como tendo agência no processo de avaliação e feedback é considerado uma área relevante sobretudo tendo em conta o contexto do ensino superior, no qual se pretende que o estudante desenvolva competências de aprendizagem ao longo da vida. Nesta investigação pretende-se investigar a disponibilidade dos docentes para ceder ao estudante algum do poder que detêm no processo de avaliação. Procura-se, também, identificar que estratégias podem ser utilizadas pelos docentes no sentido de promover este novo papel do estudante na avaliação digital. A partir de uma metodologia qualitativa, foram recolhidos dados de 58 docentes que participaram em 10 focus-group criativos, uma abordagem ao focus-group na qual, para além de se envolverem em discussão sobre as suas práticas, os participantes procuraram, em grupo, desenvolver soluções de melhoria pedagógica e tecnológica nas suas práticas de avaliação digital. Como resultado da investigação, identifica-se um conjunto de recomendações para promover maior envolvimento do estudante nas estratégias de avaliação, organizado em três temas: (i) a preparação para a avaliação; (ii) a avaliação formativa; e (iii) o feedback após a submissão.
O que os computadores continuam não conseguindo fazer, 50 anos depois: A aprendizagem sob a perspectiva da fenomenologia do cotidiano de Hubert Dreyfus
Authors: Leporace Camila De Paoli
Published: January 2023

O artigo traz uma análise teórico-filosófica de aspectos fundamentais da fenomenologia do cotidiano de Hubert Dreyfus, com o objetivo de contribuir com um olhar filosófico para a aprendizagem para além do processamento de informações. Dreyfus, que em 1972 publicou seu conhecido livro O que os Computadores Não Podem Fazer, fez uma análise da inteligência artificial que torna possível a compreensão da cognição humana para além do cérebro, das representações mentais e da computação, a partir da centralidade da experiência no corpo em acoplamento com o mundo. Com base nas ideias de Dreyfus, argumenta-se que a aquisição de conhecimento não se dá apenas de maneira representacional, computacional, mas depende da experiência desse corpo engajado com o mundo e, ainda, das suas emoções. Demonstra-se que essas ideias têm proximidade com o enativismo, uma nova abordagem à cognição que apresenta uma alternativa ao cartesianismo e faz parte de um arcabouço teórico conhecido como os 4Es da Cognição: Embodied, Embedded, Extended e Enactive, ou Corporificada, Situada, Estendida e Enativa.
Implementação do RESCUR com crianças e adolescentes surdos: perceção de professores, pais e alunos sobre o impacto ao nível do bem-estar e das aprendizagens
Authors: Freitas Eunice , Simões Celeste
Published: January 2023

A resiliência é um conceito dinâmico e interativo que se refere à capacidade de o indivíduo se ajustar e recuperar perante vários tipos de adversidades ou dificuldades mais ou menos prolongadas no tempo. Implementar programas preventivos e promotores de resiliência revela-se, assim, fundamental na infância e na adolescência, principalmente em crianças vulneráveis. O presente estudo procurou explorar a perceção de 37 crianças e adolescentes surdos, com idades compreendidas entre os 3 e os 15 anos, e respetivos pais e professores acerca do impacto da adaptação e implementação do Currículo Europeu para a Resiliência (RESCUR).

Published: January 2023

With the advent of new technologies and the growing market demand, companies have been looking for ways to improve the efficiency of their production processes, introducing innovations from the elimination of waste, reduction of rework and incongruity of information due to manual data entry . The objective of this article is to demonstrate that it is possible to mitigate or eliminate stoppages in the TV production process, caused by difficulty in reading barcodes printed on a thermal transfer printer, with intelligent and innovative solutions supported by quality tools. In the search for the resolution of these problems, this work was developed in three chapters. Chapter I begins with an introduction that presents the problem to be dealt with, what types of bar codes are adopted in the company, addresses the quality tools that were used as support in the search for the solution of the problem and also the general objective and the specifics that were defined by the researchers. Chapter II briefly presents the methodology that was applied for the development of this work, the concept of efficiency and effectiveness in the production system, details the quality tools used (PDCA, Brainstorming, 5 Whys, Ishikawa Diagram, 5W2H) to find a viable solution to the problem being addressed. It discusses the most used types of bar codes, two-dimensional and linear, among others, their structural compositions, the encoding and decoding processes, the check digit and the methods that cover the detection of incorrect typing. Chapter III presents a proposed solution for the company, based on a vastly detailed analysis of the flowchart of each area involved in the printing process and the use of barcode labels, the materials used in the printing process, which information systems are used as well as the layout and method used for printing. The result of this study tends to contribute to other enterprises that have similar bar code printing processes, since its application aims to reduce or eliminate line stops, acting directly on the bar code failures that cause so much stoppages. line, demonstrating that disruptive thinking associated with intelligent change contributes positively to the company's results by improving process and information flow, contributing to increased efficiency and reduced rework.

In this work, three machine learning approaches were evaluated for detecting anomalies in impedance-based structural health monitoring (ISHM – Impedance-based Structural Health Monitoring) of a specimen in a controlled environment. Supervised, unsupervised, and semi-supervised algorithms were chosen to compare them regarding detecting anomalies in an aluminum beam with failure induced by surface machining on one of the faces. After applying the algorithms, it was found that, of the three types of learning, supervised and semi-supervised were the ones that achieved the best accuracy in detecting anomalies. On the other hand, the unsupervised type model did not obtain good results for the conditions investigated. Thus, this can be an important technique comparison achievement for implementing real anomaly detection ISHM systems.

The present study aimed to perform an epidemiological analysis of cases of drug intoxication in Brazil from 2012 to 2021. For this, data available in the Notifiable Diseases Information System (SINAN) of the Informatics Department of the Unified Health System (DATASUS) were used, considering the drug product as a toxic agent. During the study period, there were 1,255,435 cases of intoxication in Brazil. Of these, 47.5% (n= 596,086) were caused by drug products, with prevalence in females (72.11%; n= 429,838), age group 20 to 39 years (42.06%; n= 250,718), ethnicity/white color (45.51%; n= 271,268) and schooling - high school (23.81%; n= 141,934). Regarding the circumstances that triggered drug intoxication, the main reason was the suicide attempt in 391,635 cases (65.70%), and the Southeast region presented the highest number of intoxications per drug (49.51%), followed by the South (21.80%) and Northeast region (18.71%). Most cases of drug intoxication were defined based on clinical criteria (68.24%) and only 3.35% on clinical and laboratory criteria, which evolved to cure without sequelae in 81.11% (n= 483,490) of the cases, with 1,233 deaths. These data reinforce the need for health education focused on the rational use of medications and the importance of health professionals in this process, such as pharmacists, which are the interface between the patient and the medication.

Authors: Anjos Nicole Costa dos , Harb Antonio Geraldo
Published: January 2023

In the face of an increasingly competitive scenario in the services market, numerous researchers have searched for ways to distinguish which elements make up logistic service quality (LSQ) and how these lead to customer satisfaction. Set in a company in the Industrial Pole of Manaus, this study aimed to identify the perceptions of its customers about the dimensions of its logistics service quality. For this, an online survey composed of items related to the LSQ dimensions proposed by Mentzer et al. (2001) was applied and, aided by a non-parametric test of the distributions formed by the data, a strong association was found between Order Release Quantities, Ordering Procedures and Order Accuracy and the general satisfaction of the respondents. Furthermore, the use of the importance-performance matrix by Martilla and James (1977) made it possible to recommend improvements in handling lost goods and information on product availability.

This paper aimed to determine and spatialize physical-hydric attributes in the sugarcane area at the Sugarcane Research Unit in Ceres (GO) in Cerrado (vegetation of the Brazilian interior),. The experiment comprised an area of 285 x 60 m with a 15 m sampling grid, in which a deformed and undisturbed soil sampling was carried out from January 2020 to January 2021. The evaluated attributes were: (a) clay ; (b) sand; (c) silt; (d) soil density (SD); (e) particle density (PD); (f) total porosity (TP); (g) macroporosity (macro); (h) microporosity (micro); (i) water retention in field capacity (FC); (j) water retention in the permanent wilting point (PWP); and (k) total water availability (TWA). All physical attributes showed moderate to strong spatial dependence with adjustments to Gaussian models predominantly for granulometry and exponential, and spherical for the others, ranging from 15.4 to 191.9 m. Results of TWA spatial variability allow defining two management units and show that the soil under study has low water retention in the available water range. This study provides information that enables decision-making in irrigation management and soil decompaction..
