We study radiation damage accumulation in alpha polymorph of gallium oxide (α-Ga2O3) epitaxial layers under irradiation with 40 keV monatomic P and 140 keV molecular PF4 ions. The distribution of stable structural damage is bimodal in both cases. The growth rate of the surface disordered layer under PF4 ion irradiation is significantly higher than that under monatomic P ion bombardment. At the same time, monatomic ion irradiation is more efficient in the bulk defect peak formation. Thus, the density of displacement cascades strongly affects the formation of stable damage in α-gallium oxide. The doses required to create the same level of disorder in the metastable α-polymorph are higher than that in the thermodynamically stable α-. Mechanisms of damage formation in these polymorphs are different. Keywords: gallium oxide, α-Ga2O3, ion bombardment, collision cascades, radiation damage, collision cascade density, defect engineering, radiation resistance.

Silicon light-emitting diodes with dislocation-related electroluminescence have been studied at room temperature. For the fabrication of the light-emitting diode structures, a well-known method for the formation of dislocation-related luminescence centers during anneals of silicon with a high oxygen concentration in a flow of argon was modified by introducing a preliminary O+ ion implantation and carrying out a final anneal in a chlorine-containing atmosphere. In the electroluminescence spectra, the D1 dislocation-related luminescence line dominates at currents less than <150 mA and the near-band-edge luminescence line starts to dominate with increasing current. The electroluminescence excitation efficiency for the D1 center is 3.3·10-20 cm2·s at room temperature. Keywords:: Light-emitting diodes, dislocation-related luminescence, silicon, oxygen precipitates.

Capacitance--voltage characteristics of metal dielectric semiconductor structures with atomic layer deposition Al2O3 on n- and p-Cd0.22Hg0.78Te (with and without a surface graded-gap layer) preliminary oxidized in oxygen glow discharge plasma (with the resulting oxide thickness of 2 nm) have been studied. The obtained structures reveal the positive fixed charge with a density of ~(1-6)·1011 cm-2. The ratio between a slow surface states density and a surface band gap width is almost independent on graded-gap layer presence, with the value of ~(4-8)·1011 cm-2·eV-1. The proposed passivation approach provides near-ideal low-frequency capacitance-voltages characterized by weak influence of fast surface states. Films of CdHgTe grown without the graded-gap surface layer are proved to be much more sensitive to the process of oxidation in glow discharge plasma. Keywords: mercury cadmium telluride, film, surface states, plasma.

The electrical and photovoltaic characteristics of the Ga2O3/n-GaAs structures have been studied. A gallium oxide film was obtained by HF magnetron sputtering on n-GaAs epitaxial layers with concentration of N_d=9.5·1014 cm-3. The thickness of the oxide film was 120 nm. Measurements at a frequency of 106 Hz have shown that the capacitance-voltage and conductance-voltage dependences are described by curves characteristic of metal-insulator-semiconductor structures and exhibit low sensitivity to radiation with λ=254 nm. When operating on a constant signal, the samples exhibit the properties of a photodiode and are able to work offline. The photoelectric characteristics of the detectors during continuous exposure to radiation with λ=254 nm are determined by the high density of traps at the Ga2O3/GaAs interface and in the oxide film. Keywords: MIS-structures, capacitance-voltage characteristics, volt-siemens characteristics, photocurrent, trap density.

Authors: Morozova N. K.  , Miroshnikova I. N.
Published: January 2023

Intense CdS luminescence in the blue and green spectral regions is widely used in all areas of optoelectronics. In this spectrum band are working on lasers CdS. This paper presents the results of a study of the exciton region of the CdS spectrum based on the theory of anti-intersecting bands (bands anticrossing theory-BAC) with the involvement of broader initial data for the analysis of optical properties. Depending on the growth conditions, the presence and change of oxygen concentration and intrinsic point defects determining the composition of crystals are taken into account. The concept of the nonuniform distribution of isoelectronic oxygen centers in the bulk of CdS due to their predominant segregation on compensating stacking faults is introduced. Cathodoluminescence (CL) spectra were studied using various recording methods, excitation intensity and temperature, as well as pulsed CL at high excitation intensities. In a scanning electron microscope from local registration and a high excitation density, the emission of the edge luminescence components of CdS was detected at 300 K. To analyze the optical data, we used the capabilities of the method for constructing band models based on the BAC theory, which collects extensive and multilateral information about specific samples. A model of a CdS · O multizone with stacking faults, which determines the spectrum of edge emission is presented. An explanation of the nature of the green edge emission of cadmium sulfide as excitons localized on oxygen-containing complexes in SF layers has been obtained for the first time. It was found that the system of levels of localized excitons at stacking faults does not change either with temperature up to 300 K, or with a change in the oxygen solubility in the crystal to the limiting one. It is shown that the presence of isoelectronic oxygen centers appear itself in the electro-physical properties of crystals. Recommendations are given for the diagnostics of crystals suitable for the creation of luminescent systems or lasers that are stable in operation. Keywords: isoelectronic centers, bands anticrossing theory, localized exciton, stacking faults, point defects, stimulated radiation.

Authors: Sharov M. K.
Published: January 2023

The values of the lattice period and the linear coefficient of thermal expansion (α) of Pb1-xCdxTe solid solutions are determined depending on the cadmium content and temperature using high-temperature X-ray diffractometry. An increase in the concentration of cadmium in Pb1-xCdxTe in the range x=0.02-0.08 leads to a significant increase in the linear coefficient of thermal expansion. A change in temperature range T=293-673 K leads to decrease in the linear coefficient of thermal expansion. Besides, an increase in temperature does not affect the value α of the undoped PbTe in the indicated temperature range. Keywords: lead telluride, cadmium, solid solutions, lattice period, linear coefficient of thermal expansion.

Authors: Gautam Pawan Kumar , Singh Anoop Kumar
Published: January 2023

Tectonic geomorphology has been evidenced as an essential tool to define and measure recent tectonic deformation. The Nandakini River originates from Nanda Ghunti glacier at 6886 m in Lesser Himalaya. It covers about ~551 km2 basin area, with a fourth-order stream. It confluences with the Alaknanda River near Nand Prayag (at elevation 852 m), Chamoli district of Uttarakhand. The drainage pattern is predominantly dendritic in the study area. The morphotectonic indices are measured to know the tectonic activity of the drainage basin. Morphometric indices reflecting hypsometric Integral is 1.07, indicating a deeper incision and a slight erosion. The basin elongation ratio is 0.17, suggesting that the area is tectonically active. The drainage basin asymmetric factor (44) suggest tilting. In addition, the drainage basin shape (3.27) indicates the basin is tectonically strong, the transverse topographic symmetry factor (0.31) indicates the asymmetric nature, the valley floor width to valley height ratio is 0.54 shows the deep, narrow valleys, and Active V-shaped incision. Stream longitudinal profile showing the area tectonically influenced. The Sinuosity Index of 1.12 suggests that low sinuous nature. The Stream length-gradient Index is 10.64, indicating high tectonic activity in valleys and basin areas. The transverse profile helps to understand the tilting of the basin. The Surface profile shows irregularity, and the linear trend of the profile shows the tilting of the basin. River carrying capacity with large boulder-size sediment indicates youth stage and tectonically active environment. The morphotectonic indices suggest that the drainage basin was affected by the regional structures and the present tectonics.

Published: January 2023

Background

The construction of an elimination stoma has a physical, psychological, and social impact on the person. The development of stoma self-care competence contributes to the adaptation to a new health condition and improvement of quality of life. eHealth refers to everything associated with information and communication technology and health care, including telemedicine, mobile health, and health informatics. The use of eHealth platforms by the person with an ostomy, as a digital application that includes websites and mobile phone apps, can bring scientific knowledge and well-informed practices to individuals, families, and communities. It also allows functionalities that enable the person to describe and identify early signs and symptoms and precursors of complications and to be guided to an adequate health response for their problems.

Objective

This study aimed to define the most relevant content and features to promote ostomy self-care integrated into an eHealth platform as a digital app or website to be used by patients for self-management of stoma care.

Methods

We developed a descriptive, exploratory study with a qualitative approach using the focus group methodology, which was oriented to reach a consensus of at least 80%. A convenience sample of 7 participants consisting of stomatherapy nurses was used. The focus group discussion was recorded, and field notes were taken. The focus group meeting was fully transcribed, and a qualitative analysis was performed. The research question was: Which content and features for ostomy self-care promotion should be integrated into an eHealth platform as a digital app or website?

Results

An eHealth platform, which can be a smartphone app or website, for people with ostomy should provide content aimed at promoting self-care, namely in the field of knowledge and self-monitoring, as well as the possibility of interacting with a stomatherapy care nurse.

Conclusions

The stomatherapy nurse has a decisive role in promoting adaptation to life with a stoma, namely through the promotion of stoma self-care. Technological evolution has emerged as a useful tool to enhance nursing interventions and promote self-care competence. The development of an eHealth platform aimed at promoting ostomy self-care should include the capabilities for telehealth and help with decision-making regarding self-monitoring and seeking differentiated care.

Published: January 2023

Rad je usmeren je ka iznalaženju racionalnog konceptualnog modela zaštite i očuvanja teritorijalnog integriteta i suvereniteta Srbije u kosovsko-metohijskom prostoru, čija primena ne bi ugrozila ostvarivanje njenih drugih vitalnih i važnih interesa. Polazeći od logike strateškog mišljenja, u radu se polazi od teze da takav model podrazumeva primenu prelaznog rešenja, usmerenog ka ostvarivanju posebnog strategijskog cilja koji bi imao ulogu etapnog političkog cilja. Takvim rešenjem umanjuju se rizici ostvarivanja ekonomskog razvoja Srbije i očuvanja fizičke bezbednosti njenih građana, a obezbeđuje prostor za kasnije ostvarivanje krajnjeg političkog cilja kojim se dostiže željeno stanje u strategijskom okruženju koje podrazumeva „reintegrisan prostor AP KiM u ustavno-pravnom poretku Republike Srbije“. U pogledu strategijskih pristupa i načina delovanja, konceptualni model zahteva izbegavanje ofanzivnog pristupa u vojnoj dimenziji, a primenu kombinovanog ofanzivno-defanzivnog pristupa u diplomatskoj, ekonomskoj i informacionoj dimenziji strategijskog okruženja. Način primene instrumenata nacionalne moći bio bi sekvencijalan, odnosno postepen i dugoročan, odvijao bi se u više faza, uz akumulaciju manjih strategijskih efekata. Rad pripada naučnom polju strateških studija a metodološki okvir obuhvata primenu analitičko-sintetičke, deduktivno-induktivne, istorijsko-komparativne i prognostičke metode.
CRITICAL DISCOURSE ANALYSIS AS A CRITICAL SOCIAL STUDY: NORMAN FAIRCLOUGH’S APPROACH
Authors: Pesic Milena
Published: January 2023

The initial thesis of this paper is that critical discourse analysis (CDA), as a qualitative, critical, explanatory approach in exploration of social communication, represents a valuable way of researching contemporary social/political communication, and an indispensable complement to traditional social scientific techniques, which privilege positivist paradigm, quantitative research in social/political communication examinations. Consequently, the main purpose of this paper is to point out what the uniqueness of CDA’s scientific contribution to the study of society consists of, through observing the specificity of the theoretical and methodological framework, categories and analytical procedures of CDA in Norman Fairclough’s approach. The introductory part of the article provides a summary overview of the starting points, notions and tenets of CDA. In the following section the focus is on the analytical review of the different levels of Norman Fairclough’s theoretical framework and methodological procedures of CDA. The third, final part of the article is an attempt to provide an overall view of the importance of CDA in Fairclough’s approach for critical social study.

Published: January 2023

Nowadays laser scanners play an important role in technology and research, when it comes to measure 3D coordinates physically and in real time of any object under observation. Laser scanners have to measure the 3D coordinates of these objects in shortest time and with the smallest measuring error. A novel laser scanner called Technical Vision System (TVS), which uses Dynamic Triangulation and DC motors, was developed and proven to represent a fast and reliable scanning system. Previous research used the step response of the TVS mechanical actuators (DC motors), which can overshoot if certain controller parameters of the closed-loop control are selected. If the overshoot is undesirable, a trade-off must be made between speed and overshoot of the step response. Thereby, present paper describes a new approach to control the actual angular position of the TVS DC motors using a trapezoidal profile for the DC Motor velocity. The DC motors step response is replaced by a trajectory response, which allows the reduction of the relative angular error of the DC motors shaft to a value less than or equal to 0.1 percent. Also, the design of the control system, to implement the trapezoidal trajectory profile for the DC motor velocity in practice, is described in detail.

Design and synthesis of the poly vinyl chloride (PVC) membrane as Fe(III) ion selective electrode (ISE) sensor based on EHA ionophore as an excellent sensory molecule for monitoring Fe(III) in the sample solution had been done. Simple and efficient EHA was made by condensation of carboxylic acid HA with ethanol and sulfuric acid as catalist. PVC membrane was prepared by mixed all component such as PVC powder, EHA, plasticizer (o-NPOE and DOP) and anion lipophilic (Sodium-TPB and oleic acid) with a total weight of 100 mg and dissolved in 1 mL of dry THF. The electrode membrane responses showed that the electrodes were highly selective to ion Fe3+ at pH 3 with response time of ±50 seconds. The dynamic range of the membrane ISE sensor was 10-1–10-7 M with the value of Nernst factor was ±19 mV per decade. The membrane electrode can be used for at least 5 weeks. The analytical results of Fe(III) measurement showed good confirmity with reference method (AAS), suggesting that the developed analytical tool could be used to measure and monitor Fe(III) in the real water samples.

Published: January 2023

Abstract: Art that was entirely or partially produced by an autonomous system is referred to as generative art. An autonomous system is typically a non-human entity that is capable of making judgments on its own about aspects of a piece of art that would otherwise require direct input from the artist. We have created a GUI which lists the applications which are based on the concept of generative art. Our GUI contains applications like random password generation, abstract artworks, map generation, wallpaper generation. Password generator will provide randomly generated passwords which would be derived from the images created using image generation algorithms/scripts such as EPWT and python’s in-built random function which uses algorithms like mersenne twister, a pseudo-random number generator. This application aims to provide usefulness for old hashing algorithms which are getting obsolete day by day. Abstract artwork generator will generate random images for stimulating creativity of artists, designers, architectural and marketing firms for getting started on a new project. This generator uses general complex functions which contain scripts for different shapes and combinations. This approach is able to generate some innovative solutions and demonstrates the power of computational approach. A layout of the area with the requested coordinates and different constraints will be provided through map generating model. Wallpaper generation model will generate aesthetically pleasing wallpapers with adjustable features.
An Improvised Approach of Deep Learning Neural Networks in NLP Applications
Authors: Vaghasia Rishil
Published: January 2023

Abstract: In recent years, natural language processing (NLP) has drawn a lot of interest for its ability to computationally represent and analyze human language. Its uses have expanded to include machine translation, email spam detection, information extraction, summarization, medical diagnosis, and question answering, among other areas. The purpose of this research is to investigate how deep learning and neural networks are used to analyze the syntax of natural language. This research first investigates a feed-forward neural network-based classifier for a transfer-based dependent syntax analyzer. This study presents a long-term memory neural network-based dependent syntactic analysis paradigm. This model, which will serve as a feature extractor, is based on the feed-forward neural network model mentioned before. After the feature extractor is learned, we train a recursive neural network classifier that is optimized by sentences using a long short-term memory neural network as a classifier of the transfer action and the characteristics retrieved by the syntactic analyzer as its input. Syntactic analysis replaces the method of modeling independent analysis with one that models the analysis of the entire sentence as a whole. The experimental findings demonstrate that the model has improved its performance more than the benchmark techniques.

Authors: The Aurelia Theresa Nagata , Tondok Marselinus  Sampe
Published: January 2023

Interreligious conflicts can change the state system regarding religious tolerance and the emergence of terrorist behavior. In Surabaya, terrorism incidents have occurred in three Christian churches, and the alleged perpetrators are the Islamic fundamentalist group JAD. These incidents have fueled feelings of threat and fear of death, which can lead to prejudice. This research aimed to determine the role of social dominance orientation and interreligious empathy as predictors of prejudice toward Islamic fundamentalists. It used a quantitative design with a sample of 400 Christian students aged 17-24 in Surabaya. Furthermore, SDO-7, BES-A, and the Prejudice toward Islamic Fundamentalists Scales were adopted. The results showed that social dominance orientation and interreligious empathy predicted the prejudice toward Islamic fundamentalists (R=0.056; R2=0,061; F(2, 378)=12.876; p<0.001) using multiple linear regression tests. Social dominance orientation did not significantly predict prejudice (t= -0.91426; p=0.361), unlike interreligious empathy (t=4.365; p<0.001). Therefore, intergroup relations need to consider interreligious empathy in reducing prejudice.

This study aims to determine the role of personal growth initiatives (PGI) in psychological distress among undergraduate students during the COVID-19 pandemic. This study hypothesizes that there is a role of PGI in psychological distress among undergraduate students during the COVID-19 pandemic. Respondents in this study were 200 active undergraduate students in Indonesia. The sampling technique used was purposive sampling. The measuring instruments were the General Health Questionnaire-12 (GHQ-12) and the PGI scale. The results show that PGI had a significant role in psychological distress, with F(1.198) = 13.784, p= 0.000, R2 = 0.065, and R2 adjusted = 0.060. The regression coefficient (β = -0.175) indicated that an increase in PGI, on average, could decrease the psychological distress score by 0.175. Thus, the hypothesis proposed in this study can be accepted.

The influence of bracing on the stress state of the ribbed-ring dome framework
Authors: Lebed Evgeny V.
Published: January 2023

The aim of current research was to establish the relationship between the stress state of the ribbed-ring dome framework and the degree of its bracing. It was assumed that the meridional ribs and rings of the dome framework are made of metal. The framework of the dome consists of 24 ribs and 7 rings. The study was performed for a ribbed-ring dome of spherical shape with a span of 39.3 m and a height of 11.0 m on computer models. The initial computer model of the framework of a ribbed-ring dome made of steel I-beams without bracing has been developed. On the basis of the initial model, additional models were developed for the frameworks with bracing between meridional edges in four, eight cyclically symmetric sectors and in all sectors. Both for the initial model and for all models of the dome framework with bracing, computer calculations were performed for the effect of the load from the own weight of the load-bearing and enclosing structures, and two variants of the snow load. During the calculations, deformations, internal forces and stresses in the meridional ribs, upper and intermediate rings of different models were determined, which were compared with each other. Graphs of changes in deformations of the frame, graphs and diagrams of changes in internal forces and stresses in the meridional ribs, in the upper and intermediate rings of the dome, depending on the degree of bracing in the framework, are obtained. An assessment of the influence of bracing on the stress state of the rib-ring dome frame is performed.

A Amazônia possui um papel significativo no regime climático brasileiro. Entretanto, o avanço do agronegócio e a crescente ocupação da floresta Amazônica, expressos a partir do aumento do desmatamento e das queimadas, pode significar o surgimento de crises nas demais regiões brasileiras, entre elas o Centro-Sul. Nesse sentido, o presente trabalho possui a finalidade de demonstrar, a partir do estudo da literatura especializada, a importância da Amazônia para a manutenção do clima em todo o território nacional e explicitar como o desmatamento e as queimadas na floresta influenciam no clima do Centro-Sul brasileiro. A metodologia baseia-se em levantamento bibliográfico mediante revisão de literatura. Os estudos analisados indicam que a Floresta Amazônica apresenta alta influência nos ambientes extra-amazônicos, estendendo-se à economia em nível nacional, embora seus serviços ecológicos estejam sendo reduzidos com o avanço do agronegócio e do desmatamento da floresta.

A Operação Urbana Consorciada Porto Maravilha, se refere a um conjunto de intervenções urbanas e financeiras sob justificativa de revitalização da região portuária do Rio de Janeiro. Com base nesses fatos, a investigação objetiva contribuir para uma melhor compreensão da economia política da política urbana através do dimensionamento da influência do capital internacional sobre a produção do espaço na área. A pesquisa tem particular pertinência no contexto das discussões atuais em torno da nova rodada de intervenções da gestão de Eduardo Paes na área central, através do lançamento do Projeto Reviver Centro e da renovada tentativa de consolidação do Porto Maravilha. Ademais, a investigação do incremento da participação do capital analisado poderá engendrar reflexões para o campo dos estudos urbanos, tendo em vista que os agentes internacionais não vivem no espaço da intervenção e as transformações ocorrem em função de seus interesses, que são descolados das demandas locais.

O artigo analisa as relações de gênero em escolas paraibanas, a partir das memórias da escolarização de rapazes e homens na Educação de Jovens e Adultos. Com pesquisa fundamentada na História Cultural, especificamente nos estudos de gênero, utilizou-se a metodologia da História Oral temática, com entrevistas de dez estudantes do sexo masculino de escolas públicas de João Pessoa, Paraíba. As memórias dos estudantes sobre sua escolarização (entre anos 1950 e 2000), desvelam a concepção de que existiria uma suposta ‘natureza’ distinta para os sexos biológicos, determinando comportamentos de homens e mulheres. Assim, garotos seriam propensos à bagunça, enquanto garotas seriam dedicadas aos estudos. Conclui-se que essa percepção contribui para a manutenção de fronteiras entre o feminino e o masculino no cotidiano escolar.
Educação escolar quilombola

Published: January 2023

O presente artigo analisa documentos legais sobre a trajetória educacional do/a negro/a no Brasil. Como se sabe, a história da educação deste país mostra assimetrias nos direitos educacionais do/a negro/a, visto que esbarravam em restrições da própria legislação. Pelo viés qualitativo e documental, o estudo discute a Educação Quilombola na Educação Escolar Quilombola e os desdobramentos dos Planos de Educação, da Base Nacional Comum Curricular e do Projeto Político Pedagógico, mostrando que essa educação é uma demanda da população negra e requer pedagogia própria, respeito às especificidades étnico-raciais e culturais. Os resultados apontam para a necessidade de formação docente específica, continuada e de materiais didáticos e paradidáticos adequados às singularidades das comunidades. Os aparatos legais são vastos, e a urgência reside em apropriar-se desse conhecimento e fazê-los valer na prática, com a implementação das leis já existentes.
Cidades Educadoras e gestão escolar democrática
Authors: Dutra Thiago , Gerhardt de Barcelos Renata , Heberlê de Almeida Lia
Published: January 2023

O objetivo deste estudo é refletir sobre as interfaces entre as ideias de Cidades Educadoras e gestão escolar democrática, que possibilitem o desenvolvimento de um modus operandi de cidadãos/ãs participativos/as na reinvenção da escola e das cidades enquanto territórios educativos democráticos geradores de aprendizagens significativas, da infância à velhice. Por meio de análise bibliográfica incluindo Paulo Freire, Jaqueline Moll, Zygmunt Bauman, Néstor Canclini, entre outros, e da experiência dos/as autores/as como gestores/as de escolas públicas, demonstra-se que a escola deve ser organizada de forma democrática e participativa por professores/as, funcionários/as, estudantes e pela presença ativa da comunidade nas decisões. Já a cidade, para que seja educadora, precisa se organizar democraticamente, dando voz a cidadãos/ãs e buscando interações, de forma a educar. Nesse sentido, a gestão democrática é uma possibilidade, além de administrativa e educacional, que proporciona práticas de participação coletiva.

O objetivo deste texto é estudar as estratégias do Sindicato dos Trabalhadores em Educação do Estado da Bahia – APLB-Sindicato durante a pandemia da COVID-19, ao identificar riscos a trabalhadores e trabalhadoras em educação. Como caminho metodológico, realizou-se análise documental dos informativos produzidos pelo sindicato e pelo governo, entre março de 2020 até a retomada das aulas em 2021 (remota e semipresencialmente). Adotou-se a perspectiva de análise marxista para explicitar a relação do par dialético essência e aparência. Concluiu-se que as informações obtidas pela APLB-Sindicato junto aos/às professores/as da rede pública de ensino subsidiaram inúmeros debates e negociações com o governo estadual, desde 2020, durante a pandemia; além disso, podem dar suporte à formulação de políticas públicas para a educação e estreitar o diálogo entre gestores/as estaduais e representantes da categoria.

Este estudo propõe problematizar a plataformização da educação, estratégia da Nova Gestão Pública – NGP para controle do trabalho docente. A revisão da literatura e a análise documental sobre a rede estadual de educação pública da Bahia indicam que, a partir do estabelecimento do ensino remoto na pandemia da Covid-19, em 2020, ampliou-se o uso de ferramentas tecnológicas associadas à NGP na educação. Tais mecanismos de controle estão presentes na ação docente, desde a formação, cada vez mais instrumental, perpassando os processos de ensino e alcançando o monitoramento de resultados, com indicadores impostos a redes de ensino e unidades escolares. Foi possível mapear intenções, estratégias e resultados da regulação da ação docente e depreender que a plataformização atende a imposição de uma agenda global de educação e que o controle da ação docente aponta para o cerceamento da autonomia do/a professor/a.

Published: January 2023

Los sistemas de gestión de la seguridad y salud en el trabajo han evolucionado en las últimas décadas, principalmente por las regulaciones legales impulsadas por los gobiernos nacionales, fomentando con ello la generación de políticas públicas de empleo. El cumplimiento y desarrollo de los sistemas de gestión permite impulsar y ejecutar diferentes métodos de medición de la gestión y el desempeño de la seguridad y salud en el trabajo; sin embargo, existen limitaciones y fallas relacionadas con estos componentes. Este artículo tuvo como propósito presentar los resultados de una revisión sistemática que indaga por las estrategias de medición del desempeño de los sistemas de gestión por medio de la conceptualización del desempeño y su aplicación, la presentación de métodos que se han documentado en la literatura para dicha medición, así como los de mayor uso y sus principales ventajas, desventajas y la eficacia de estos. Para ello, se revisó la literatura de treinta y ocho artículos publicados entre 2002-2021 en Science Direct, Scielo, Pubmed y Redalyc, lo que permitió identificar sesenta y un aspectos relacionados con el desempeño de la seguridad y salud en el trabajo y siete modelos de medición del desempeño. De acuerdo con la estructura y necesidades de las organizaciones, se establece que estas pueden utilizar métodos específicos para la medición del desempeño de la seguridad y salud en el trabajo; no obstante, algunos métodos o herramientas presentan niveles elevados de complejidad y metodologías de evaluación que no pueden ser aplicadas por las pequeñas y medianas empresas, mientras que otros instrumentos, como la herramienta diagnóstica de la gestión de la seguridad y salud en el trabajo integra diferentes componentes que facilitan un seguimiento riguroso a la gestión de la seguridad y salud en el trabajo con un enfoque de medición superior para cualquier tipo de organización.

Aims: This study aimed to evaluate the effect of remifentanil
pretreatment on sufentanil-induced cough (SIC) during general anesthesia
induction. Methods: A total of 120 patients who were scheduled for
elective surgery were equally randomized into two groups (n=60 each).
Patients in R group received 0.5 μg/kg remifentanil and N group received
same volume of normal saline 1 minute before sufentanil (0.5 μg/kg)
intravenous injection. Remifentanil and sufentanil were diluted to 5ml
and then administered to patients in both R and N groups within 5
seconds. Then midazolam, etomidate and rocuronium bromide were given to
facilitate tracheal intubation. The incidence and severity of cough in
both groups were recorded within 2 minutes after sufentanil
administration during general anesthesia induction. The mean arterial
pressure (MAP), heart rate (HR), and pulse oxygen saturation (SpO2) were
recorded at T1 (before the injection of remifentanil or normal saline),
T2 (1 minute after remifentanil administration), T3 (before intubation)
and T4 (1 minute after intubation). Additionally, the incidences of
adverse events, including dizziness, nausea, apnea, truncal rigidity,
bradycardia or other adverse effects were also recorded. Results: The
incidence of SIC in R group was significantly decreased when compared
with N group (3.33% vs 35.00%, respectively; P < 0.001). No
statistical differences were found in MAP, HR, SpO2, and the incidences
of other side effects between two groups at T1, T2, T3, and T4 (P
> 0.05). Conclusion: Pretreatment with remifentanil 0.5
μg/kg can effectively and safely suppress the incidence and severity of
sufentanil-induced cough.

Error Augmentation training using a robotic interface is thought to
promote motor recovery by enhancing proprioceptive feedback, which
motivates and challenges patients to optimize their performance during
training. Here, we investigated the effectiveness of robotic Error
Augmentation training on motor recovery after a stroke, compared to
standard robotic training in a null field. Post-stroke patients were
randomly assigned to one of two groups: a study group (n=9) that was
trained on a 3D robotic system applying Error Augmentation forces, and a
control group (n=7) that carried out the same protocol in null field
conditions. The robotic rehabilitation intervention was applied in
addition to the standard rehabilitation protocol of the rehabilitation
center. Error Augmentation training increased clinical scores compared
to standard robotic training by 266% on the Motor Assessment Scale, and
88% on the Fugl-Meyer scale. The Motor Assessment Scale scores were
significantly correlated with the Fugl-Meyer scores (p=0.03, r=0.541).
There were more movement errors on the initial trials of the game
sequence using the DeXtreme robotic device with Error Augmentation
compared to trials with no force field. This difference vanished however
after 10 trials. Error Augmentation training decreased the number of
movement units and jerkiness compared to the control treatment. These
findings suggest that Error Augmentation training may enhance motor
performance possibly through motor adaptation.

Published: January 2023

Oral mucosal lesions may persist years before diagnosis of inflammatory
bowel disease (IBD) and subsequent primary sclerosing cholangitis (PSC).
It may be that a dental practitioner may be the first clinician to
suspect IBD. Suspect IBD; early referral and close collaboration with a
gastroenterologist are recommended.
