Research on MapReduce Heuristic Multi Table Join Algorithm Based on
Binary Optimization and Pancake Parallel Strategy
Authors: Jia Songhao , Yang Jizheng , Yang Cai , Zhang Haiyu
Published: October 2022

Background:

With the development of technology, the data amount has increased significantly.
In data processing, the multi table query is the most frequent operation. Because the join
keys cannot correspond one by one, there will be much redundant data transmission, resulting in a
waste of network bandwidth.

Objective:

In order to solve the problems of network overhead and low efficiency, this paper proposes
a heuristic multi table join optimization method. By sharing information, the unconnected tuples
are eliminated so as to reduce the amount of data transmitting. This shortens response time and
improves execution performance.

Method:

Firstly, the join key information of one table is compressed by the algorithm to make the
filtered information for sharing. Then, the concurrent execution is controlled according to the pancake
parallel strategy. Finally, the selection strategy of multi table join order is proposed.

Results/Discussion:

The experiments show that the proposed algorithm can filter a large amount of
useless data and improve query efficiency. At the same time, the proposed algorithm reduces a lot of
network overhead, improves the algorithm performance, and better solves the problem of low efficiency
of multi table join.

Conclusion:

This paper introduces the heuristic strategy to optimize the algorithm, so that it can
perform the join tasks in parallel, which further improves the performance of multi table join. The
algorithm creatively combines heuristic data filtering, which greatly improves the quality of data
processing. The algorithm is worth popularizing and applying.

Published: October 2022

Background

Globally, COVID-19–related psychological distress is seriously eroding health care workers’ mental health and well-being, especially in low-income countries like Nigeria. The use of mobile health (mHealth) interventions is now increasingly recognized as an innovative approach that may improve mental health and well-being. This project aims to develop an mHealth psychological intervention (mPsyI) to reduce COVID-19–related psychological distress among health care workers in Nigeria.

Objective

Our objective is to present a study protocol to determine the level of COVID-19–related psychological distress among health care workers in Nigeria; explore health care workers’ experience of COVID-19–related psychological distress; develop and pilot test mPsyI to reduce this distress; and assess the feasibility of this intervention (such as usability, engagement, and satisfaction).

Methods

A mixed (quantitative and qualitative) methods approach is used in which health care workers will be recruited from 2 tertiary health care facilities in southwest Nigeria. The study is divided into 4 phases based on the study objectives. Phase 1 involves a quantitative survey to assess the type and levels of psychosocial distress. Phase 2 collects qualitative data on psychosocial distress among health care workers. Phase 3 involves development of the mHealth-based psychological intervention, and phase 4 is a mixed methods study to assess the feasibility and acceptability of the intervention.

Results

This study was funded in November 2020 by the Global Effort on COVID-19 Health Research, and collection of preliminary baseline data started in July 2021.

Conclusions

This is the first study to report the development of an mHealth-based intervention to reduce COVID-19–related psychological distress among health care workers in Nigeria. Using a mixed methods design in this study can potentially facilitate the adaptation of an evidence-based treatment method that is culturally sensitive and cost-effective for the management of COVID-19–related psychological distress among health care workers in Nigeria.

Use of Telemedicine in Pediatric Services for 4 Representative Clinical Conditions: Scoping Review
Authors: Southgate Genevieve , Yassaee Arrash A , Harmer Matthew J , Livesey Helen , Pryde Kate , Roland Damian
Published: October 2022

Background

Telemedicine is becoming routine in health care. Postpandemic, a universal return to face-to-face consultations may risk a loss of some of the advantages of telemedicine. However, rapid implementation and adoption without robust evaluation of usability, efficacy, and effectiveness could potentially lead to suboptimal health outcomes and downstream challenges to providers.

Objective

This review assesses telemedicine interventions against international guidance and sufficiency of evidence to support postpandemic utilization in pediatric settings.

Methods

This scoping review was performed following searches on PubMed, Embase, and CINAHL databases on April 15, 2021, and May 31, 2022, and examined studies focused on telemedicine, remote consultation, video call, or remote patient monitoring in children (0-18 years) receiving outpatient care for diabetes, asthma, epilepsy, or renal disease. Exclusion criteria included studies published before 2011 as the technologies used have likely been improved or replaced, studies in adult populations or where it was not possible to disaggregate data for participants younger than 18 years as the focus of the review was on pediatric care, and studies not published in English. Data were extracted by 4 authors, and the data were corroborated by a second reviewer. Studies were examined for feasibility and usability, clinical and process outcomes, and cost-effectiveness.

Results

Of the 3158 studies identified, 56 were suitable for final inclusion and analysis. Data on feasibility or usability of interventions (48 studies) were overwhelmingly positive in support of telemedicine interventions, with common themes including convenience, perceived cost savings, and ease of use. However, use in preference to usual care was rarely explored. Clinical and process outcome data (31 studies) were mostly positive. Across all studies, there was limited measurement of standardized clinical outcomes, although these were more commonly reported in asthma (peak flow) and diabetes (glycated hemoglobin [HbA1c]). Implementation science data generally supported cost-effectiveness of telemedicine with a reduction of health care costs.

Conclusions

There is promising evidence supporting telemedicine in pediatric settings. However, there is a lack of evaluation of telemedicine in comparison with usual outpatient care for noninferiority of clinical outcomes, and this review highlights the need for a more standardized approach to evaluation of digital interventions.
Developing and Integrating Asynchronous Web-Based Cases for Discussing and Learning Clinical Reasoning: Repeated Cross-sectional Study
Authors: Tat Sonny , Shaukat Haroon , Zaveri Pavan , Kou Maybelle , Jarvis Lenore
Published: October 2022

Background

Trainees rely on clinical experience to learn clinical reasoning in pediatric emergency medicine (PEM). Outside of clinical experience, graduate medical education provides a handful of explicit activities focused on developing skills in clinical reasoning.

Objective

In this paper, we describe the development, use, and changing perceptions of a web-based asynchronous tool to facilitate clinical reasoning discussion for PEM providers.

Methods

We created a case-based web-based discussion tool for PEM clinicians and fellows to post and discuss cases. We examined website analytics for site use and collected user survey data over a 3-year period to assess the use and acceptability of the tool.

Results

The learning tool had more than 30,000 site visits and 172 case comments for the 55 published cases over 3 years. Self-reported engagement with the learning tool varied inversely with clinical experience in PEM. The tool was relevant to clinical practice and useful for learning PEM for most respondents. The most experienced clinicians were more likely than fellows to report posting commentary, although absolute rate of commentary was low.

Conclusions

An asynchronous method of case presentation and web-based commentary may present an acceptable way to supplement clinical experience and traditional education methods for sharing clinical reasoning.
Evaluating Health Care Provider Perspectives on the Use of Mobile Apps to Support Patients With Heart Failure Management: Qualitative Descriptive Study
Authors: Sivakumar Bridve , Lemonde Manon , Stein Matthew , Goldstein Sarah , Mak Susanna , Arcand JoAnne
Published: October 2022

Background

Nonadherence to diet and medical therapies in heart failure (HF) contributes to poor HF outcomes. Mobile apps may be a promising way to improve adherence because they increase knowledge and behavior change via education and monitoring. Well-designed apps with input from health care providers (HCPs) can lead to successful adoption of such apps in practice. However, little is known about HCPs’ perspectives on the use of mobile apps to support HF management.

Objective

The aim of this study is to determine HCPs’ perspectives (needs, motivations, and challenges) on the use of mobile apps to support patients with HF management.

Methods

A qualitative descriptive study using one-on-one semistructured interviews, informed by the diffusion of innovation theory, was conducted among HF HCPs, including cardiologists, nurses, and nurse practitioners. Transcripts were independently coded by 2 researchers and analyzed using content analysis.

Results

The 21 HCPs (cardiologists: n=8, 38%; nurses: n=6, 29%; and nurse practitioners: n=7, 33%) identified challenges and opportunities for app adoption across 5 themes: participant-perceived factors that affect app adoption—these include patient age, technology savviness, technology access, and ease of use; improved delivery of care—apps can support remote care; collect, share, and assess health information; identify adverse events; prevent hospitalizations; and limit clinic visits; facilitating patient engagement in care—apps can provide feedback and reinforcement, facilitate connection and communication between patients and their HCPs, support monitoring, and track self-care; providing patient support through education—apps can provide HF-related information (ie, diet and medications); and participant views on app features for their patients—HCPs felt that useful apps would have reminders and alarms and participative elements (gamification, food scanner, and quizzes).

Conclusions

HCPs had positive views on the use of mobile apps to support patients with HF management. These findings can inform effective development and implementation strategies of HF management apps in clinical practice.
Use of an Interactive Obesity Treatment Approach in Individuals With Severe Mental Illness: Feasibility, Acceptability, and Proposed Engagement Criteria (Preprint)
Authors: Nicol Ginger , Jansen Madeline , Haddad Rita , Ricchio Amanda , Yingling Michael , Schweiger Julia , Keenoy Katie , Evanoff Bradley , Newcomer John W
Published: October 2022

BACKGROUND

Digital and mobile health (mHealth) interventions are increasingly being used to support healthy lifestyle change, including in certain high-risk populations such as those with severe mental illnesses (SMI). Life expectancy in this population lags 15 years behind counterparts in the general population, primarily due to obesity-related health conditions.

OBJECTIVE

We tested the feasibility and usability of a 12-week interactive obesity treatment approach (iOTA) to adults with chronic severe mental illness (SMI) (Depression, Bipolar Disorder and Schizophrenia Spectrum Disorder) receiving treatment in community settings. The iOTA incorporates short message service (SMS) text messages to supplement monthly in-person health coaching.

METHODS

Factors hypothesized to be associated with weight change were illness severity and treatment engagement. “Severe” psychiatric symptoms were defined as baseline Clinical Global Impression (CGI) Severity score of >5. Criterion engagement was defined as a text messaging response rate >80% during the first 4 weeks of treatment. Disordered eating, assessed with the Loss of Control Over Eating Scores (LOCES), was also evaluated. Participants provided qualitative data, further informing assessment of intervention feasibility, usability, and acceptability.

RESULTS

Twenty-six participants were enrolled. The mean age was 48.5 years (SD 15.67); n=10/26 (40%) were Black and n=15/26 (60%) female. Participants with lower symptom severity and adequate engagement demonstrated significantly decreased weight (F1,16=22.54, P<.001). Conversely, high symptom severity and lower text message response rates were associated with trend-level increases in weight (F1,7=4.33, P=.08). Loss of control eating was not observed to impact treatment outcome. Participants voiced preference for combination of live health coaching and text messaging, expressing desire for personalized message content.

CONCLUSIONS

These results demonstrate the feasibility of delivering an adapted iOTA to SMI patients receiving care in community settings and suggest testable criteria for defining sufficient treatment engagement and psychiatric symptom severity, two factors known to impact weight loss outcomes. These important findings suggest specific adaptations may be needed for optimal treatment outcomes in individuals with SMI.
Twitter's Role in Combating the Magnetic Vaccine Conspiracy Theory: Social Network Analysis of Tweets (Preprint)
Authors: Ahmed Wasim , Das Ronnie , Vidal-Alaball Josep , Hardey Mariann , Fuster-Casanovas Aïna
Published: October 2022

BACKGROUND

The popularity of the magnetic vaccine conspiracy theory and other conspiracy theories of a similar nature creates challenges to promoting vaccines and disseminating accurate health information.

OBJECTIVE

Health conspiracy theories are gaining in popularity. This study's objective was to evaluate the Twitter social media network related to the magnetic vaccine conspiracy theory and apply social capital theory to analyze the unique social structures of influential users. As a strategy for web-based public health surveillance, we conducted a social network analysis to identify the important opinion leaders sharing the conspiracy, the key websites, and the narratives.

METHODS

A total of 18,706 tweets were retrieved and analyzed by using social network analysis. Data were retrieved from June 1 to June 13, 2021, using the keyword vaccine magnetic. Tweets were retrieved via a dedicated Twitter application programming interface. More specifically, the Academic Track application programming interface was used, and the data were analyzed by using NodeXL Pro (Social Media Research Foundation) and Gephi.

RESULTS

There were a total of 22,762 connections between Twitter users within the data set. This study found that the most influential user within the network consisted of a news account that was reporting on the magnetic vaccine conspiracy. There were also several other users that became influential, such as an epidemiologist, a health economist, and a retired sports athlete who exerted their social capital within the network.

CONCLUSIONS

Our study found that influential users were effective broadcasters against the conspiracy, and their reach extended beyond their own networks of Twitter followers. We emphasize the need for trust in influential users with regard to health information, particularly in the context of the widespread social uncertainty resulting from the COVID-19 pandemic, when public sentiment on social media may be unpredictable. This study highlights the potential of influential users to disrupt information flows of conspiracy theories via their unique social capital.
The Health Innovation Research School: development of a national multidisciplinary doctoral education program supporting and facilitating digital transformation in the healthcare system (Preprint)
Authors: Nygren Jens , Lundgren Lina , Bäckström Ingela , Svedberg Petra
Published: October 2022

UNSTRUCTURED

Digital health technologies have the potential to transform healthcare services to be more cost-effective, coordinated, and accessible on equal terms for entire populations. In the future, people will be assisted by such technologies to monitor their health status, taking preventive measures, and having more control of their health situation. An increase in digital supplementation or substitution of physical care visits can potentially add value to patients and care providers by increasing accessibility, safety and quality of care. However, healthcare organizations struggle with the challenges of developing and implementing digital health technologies and services in practice. As a response to this, we have developed a national multidisciplinary research school to increase competence and capacity for research on the development, implementation, and dissemination of digital health technology solutions. Through enhanced collaboration with business and public sector partners the research school will increase preparedness to support and facilitate the ongoing digital transformation of the healthcare system. A network of seven universities in Sweden was established as the basis for a two-year process to; 1) develop the forms of collaboration and coordination between the doctoral education programs at the universities, 2) establish and develop relationships with partners from industry and the public sector for joint research training projects, and 3) jointly formulate research-oriented and societally relevant research focus, goals and objectives for a research school in health innovation. The network-based development process resulted in the Health Innovation Research School with an ambition to strengthen the national capacity for healthcare improvement through health innovation. Results from the development work include; 1) a partner network, 2) scope, structure, management and activities of the research school such as a co-production model, format and roles for activities, seminars and meetings, an internationalization strategy, a communication and publication strategy and a management organization, 3) structure, courses and activities for the doctoral education process, 4) procedures for recruitment and admission of students and, 5) models for supervision of doctoral students.The network of several partners from industry, public sector and academia enables the research school to pose research questions that can solve relevant societal problems related to the development, evaluation, implementation and dissemination of methods and processes assisted by digital technologies. Ultimately, this will promote innovation to improve health outcomes, quality of care and prioritizations of resources.

RECELOS Y ENVIDIAS: VIOLENCIAS SUTILES DE GÉNERO EN LA ACADEMIA NEOLIBERALIZADA
Authors: Castelao-Huerta Isaura
Published: October 2022

Este artículo muestra cómo las envidias son una forma de violencia sutil de género al interior de la academia. Las profesoras titulares de la Universidad Nacional de Colombia que forman parte de esta investigación perciben que son envidiadas por su producción académica dentro de un sistema androcéntrico que desvaloriza los conocimientos y los aportes de las mujeres, en un contexto neoliberal de escasez de recursos que dificulta la investigación y la producción científica, pero que estimula económicamente a quienes logran productos académicos. De este modo, la percepción de la envidia por el crecimiento profesional deviene en relaciones sinuosas entre colegas, llevando a las profesoras al autoaislamiento. Al mismo tiempo, esto tiene consecuencias para sus estudiantes, ya que obstaculizar su avance académico es una forma de dañar a las docentes.
Journalists’ Social Identity: The Case of Two Calgary Newspapers
Authors: Tennant James Ian
Published: October 2022

When Postmedia bought Sun Media in 2014, it gained control of competing daily newspapers in Ottawa, Calgary, and Edmonton. Postmedia already owned the Calgary Herald and now controlled the Calgary Sun. The merger of the two newspapers’ newsrooms provided an opportunity to analyze journalists’ self-perceptions using Social Identity Theory. Journalists’ identification with their pre-merger newspaper persisted after the newsroom merger, an allegiance that may dissipate over time. In the meantime, journalists adapted to this merger of newspaper rivals by identifying with one masthead over the other depending on who the journalist is talking to.

A conservação da biodiversidade e outros serviços ecossistêmicos (SE) é de grande importância no campo das propriedades rurais em países de alta biodiversidade como a Colômbia, onde as comunidades locais priorizam outra série de atividades produtivas. Os métodos e resultados da implementação de uma metodologia de mapeamento participativo (MP) são apresentados para gerar cenários de concertação para a gestão de SE, através de quatro estudos de caso em propriedades rurais do corregimiento El Prodigio, município de San Luis (Antioquia, Colômbia). ). Foi adotada uma metodologia baseada nas abordagens de a) SE b) Pesquisa do Sistema Agropecuário ec) MP. Em cada propriedade rural, foram construídos de forma participativa quatro cenários de produção-conservação denominados atual (I), do proprietário (II), ambicioso (III) e concertado (IV), além disso, foram aplicadas entrevistas semiestruturadas para avaliar a percepção da conservação do SE pelos proprietários. Os resultados do processo de MP nos quatro cenários de análise por propriedade, permitem compreender as propriedades diferenciadas em termos de alocação de áreas para conservação e/ou produção no presente e na projeção futura. Conclui-se que o método PM é útil para desenhar estratégias de conservação-produção em ecossistemas ao nível da fazenda.
La forme urbaine patrimonialiste: limites de l'action de l'État dans la production de l'espace urbain au Brésil
Authors: Ferreira João Sette Whitaker
Published: October 2022

Les politiques publiques urbaines au Brésil reposent sur une confiance excessive dans le potentiel transformateur de l'appareil d'État et de la planification urbaine. En effet, le modèle étatique de référence est celui des économies régulées de l'État-Providence, dans lequel la production de l'espace urbain est le résultat de l'action d'un État fort. Mais ce modèle ne correspond ni à la sociabilité brésilienne, ni à notre forme urbaine. S'agissant de l'espace urbain, il convient d'élaborer une théorie de l'État qui puisse rendre compte des spécificités de notre société patrimonialiste. La théorie de la dérivation de l'État nous permet de déduire que la forme urbaine dérive de cette sociabilité spécifique, définissant un processus qui n'est pas celui de la production sociale de l'espace, mais plutôt celui de la production patrimonialiste de l'espace – un modèle de domination à travers l'espace qui entretien la société des élites.
Using the Environment to Understand non-Markovian Open Quantum Systems
Authors: Gribben Dominic , Strathearn Aidan , Fux Gerald E. , Kirton Peter , Lovett Brendon W.
Published: October 2022

Tracing out the environmental degrees of freedom is a necessary procedure when simulating open quantum systems. While being an essential step in deriving a tractable master equation it represents a loss of information. In situations where there is strong interplay between the system and environmental degrees of freedom this loss makes understanding the dynamics challenging. These dynamics, when viewed in isolation, have no time-local description: they are non-Markovian and memory effects induce complex features that are difficult to interpret. To address this problem, we here show how to use system correlations, calculated by any method, to infer any correlation function of a Gaussian environment, so long as the coupling between system and environment is linear. This not only allows reconstruction of the full dynamics of both system and environment, but also opens avenues into studying the effect of a system on its environment. In order to obtain accurate bath dynamics, we exploit a numerically exact approach to simulating the system dynamics, which is based on the construction and contraction of a tensor network that represents the process tensor of this open quantum system. Using this we are able to find any system correlation function exactly. To demonstrate the applicability of our method we show how heat moves between different modes of a bosonic bath when coupled to a two-level system that is subject to an off-resonant drive.
Conocimientos acerca del Virus de Inmunodeficiencia Humana de estudiantes de las comunas de Coyhaique, Aysén y Cisnes.
Authors: Flores-Garcés Leonardo , Conei-Valencia Daniel , Flores-Uribe Loreto
Published: October 2022

Introducción: En Chile, la incidencia del Virus de Inmunodeficiencia Humana (VIH) ha registrado un aumento de 173% entre los años 2010 a 2019, existiendo 15 mil personas portadoras del virus sin saberlo, destacando la población adolescente. En la Región de Aysén, entre el 2016 y 2017 el aumento fue de 81%. El principal factor de esta alza es la falta de información adecuada sobre sexualidad, por lo que el objetivo de estudio fue describir los conocimientos acerca del VIH de estudiantes adolescentes de las comunas de Coyhaique, Aysén y Cisnes. 
Material y método: estudio descriptivo transversal, de muestreo no probabilístico por conveniencia, a 445 estudiantes de 14 a 19 años de la Región de Aysén, a quienes se les aplicó el Cuestionario de Prevención del SIDA de Ballester et al adaptado y una encuesta de caracterización sociocultural y uso de sustancias.
Resultados: 45,6% consume alcohol, 24,7% tabaco y el 19% marihuana. El 80% ha recibido información sobre métodos anticonceptivos, infecciones de transmisión sexual y específicamente sobre VIH/SIDA, el 90,1% ha sido informado, reconociendo formas de transmisión y mitos. El 30,5% sabe que se transmite a través de lactancia o compartir una máquina de afeitar (31,7%), el 33,4% piensa que se puede infectar a través de la orina, la mayor parte sabe que para detectar la enfermedad es necesario una prueba sanguínea (80,3%) y declaran conocer el lugar donde se la pueden realizar (61,6%).
Conclusiones: la información recibida se considera deficiente o regular, desconociendo aspectos fundamentales en la prevención como el periodo de ventana y el uso constante de preservativo masculino.

Objetivo: Conocer la repercusión de la obesidad en la vida sexual de mujeres adultas de América entre los años 2010 y 2021.
Metodología: Revisión bibliográfica tipo narrativa. Se realizó una búsqueda de artículos en las bases de datos EBSCO, Lilacs, Science Direct, Scielo, Web of Science y Pubmed con los siguientes términos de búsqueda Decs: “Obesidad”, “Salud Sexual”, “Femenina”, “Patología”, “Desarrollo Psicosexual” y los términos Mesh: “Disfunción sexual”, “Psicológica”, “Mujeres” y “Conducta sexual” y sus equivalentes en inglés.
Resultados: Entre un 10% y un 60% de mujeres obesas presentan disfunciones sexuales, principalmente falta de deseo, excitación y dificultad para alcanzar el orgasmo, desencadenando inactividad e insatisfacción sexual. Existe una relación entre la obesidad y la insatisfacción con la imagen corporal y la baja autoestima, lo que ocasiona cuadros como depresión, angustia, estrés, ansiedad por el desempeño sexual y pensamientos negativos. La autoimagen negativa también se relaciona con la poca participación que tienen en los encuentros sexuales, lo que les provoca una desconexión con su cuerpo que no les permite reconocer sus necesidades emocionales ni sexuales.
Conclusión: La vida sexual de las mujeres obesas es un reto a investigar, ya que sus problemas involucran la dimensión biopsicosocial cuyo abordaje debe ser multidisciplinario.
Importante: Estudio derivado de proceso de tesina de pregrado. Las autoras declaran no tener conflicto de intereses.
Effect of Increasing Body Mass Index On the Activity of Matrix Metalloproteinase-2
Authors: Jain Richa , Das Biswajit , Saxena Shikha , Gupta Gaurav
Published: October 2022

The Increasing Body Mass Index is one of the major concerns in today's lifestyle, which may give rise to various disorders. Studies have suggested that Matrix Metalloproteinases (MMPs) are associated with Obesity and cardiovascular disease. This study aimed to evaluate the serum activity of Matrix Metalloproteinase-2 in overweight patients with anthropometric measurements to assess the effect of body mass index in MMP-2 activity. In this Age and sex matched case-control study the participants were selected in 2:1 ratio (219 cases and 108 controls). In this study Body Mass Index, Blood Pressure, and other biochemical parameters i.e. Fasting Blood Sugar (FBS), Total Cholesterol (TC), Triglycerides (TG), High-density lipoprotein cholesterol (HDL-C), Low-density lipoprotein cholesterol (LDL-C) along with MMP-2 were measured through semi-autoanalyzer and ELISA respectively. There was an increased concentration of FBS in overweight patients compared to the control group, which was statistically significant. In the case of lipid profile, there was an elevated concentration of TC, TG, and LDLC in the overweight population when compared to the control group and the findings were statistically significant, while HDL-C was significantly elevated in the control group compared to the case group. With respect to blood pressure, a significant increase was observed in systolic and diastolic blood pressure. In this study, there was a significant elevation of MMP-2 in the case group compared to the control group, which was positively associated with Body Mass Index. The outcome of this study revealed that increasing body weight might be the root cause of developing several life-threatening risk factors if not considered at initial level. Furthermore, altered concentration of MMP-2 in overweight patients may highlight cardiovascular Risk in these patients. (authors need to rewrite the abstract systematically.

Quantitative Assessment of Effectiveness and Utilization of Medical Equipment
Authors: Chowdhuri Isha Roy , Kiran Pal Arun
Published: October 2022

The problem of operational efficiency assessment of medical equipment is becoming crucial, due to its increasing requirement in hospitals. It has been observed that a significant amount of medical equipment is out of service for several reasons such as lack of training, maintenance and health technology management. The unexpected failures, downtime associated with breakdown and make ready, loss of production and poor maintenance costs of medical equipment are the major drawback in any hospital. Quality of diagnostic and treatment care provided to patients largely depends on the reliability, availability and maintainability of sophisticated medical equipment. Aim of the present study is to determine quantitatively overall effectiveness and utilization of some medical equipment. Overall Equipment Effectiveness (OEE) and utilization coefficient is the metric measurement of Total Productive Maintenance (TPM) which specifies effective functioning of devices.  The results of the effectiveness of the devices are found to be below the standard of 85%. The cause of low effectiveness value was due to poor performance and availability. Equipment utilization is also needed for the evaluation of medical equipment necessity, appropriateness and efficiency of the use in diagnosis and treating a patient. The proposed methodology may be able to increase the amount of working medical equipment by implementing preventive maintenance schedule. The methodology is also validated by failure probability and reliability of the machines.

A educação atual estabelece uma quebra de paradigmas para efetivar a inclusão de alunos da Educação Especial no ensino regular na perspectiva da Educação Inclusiva. Esse processo é desafiador para a escola e para os professores que têm alunos com deficiência. A pesquisa objetivou investigar quais as dificuldades e desafios enfrentados pelos professores nos Anos Finais do Ensino Fundamental com relação ao processo de inclusão de alunos com deficiência intelectual. Utilizou-se a metodologia qualitativa de caráter exploratório com aplicação de questionários e de entrevistas semiestruturadas. Como aporte teórico, são evidenciados os estudos de Mantoan (2003), Pletsch e Glat (2012), Oliveira (2017), Michel, (2005), Gil (1999), entre outros. Os resultados apontam que, apesar da necessidade de incluir os alunos com deficiência intelectual no ensino regular, os professores enfrentam dificuldades, como a ausência de formação voltada à inclusão, o processo de inclusão, conhecer os alunos de forma integral, escassez de recursos tecnológicos e a aprendizagem dos alunos com deficiência intelectual. Portanto, faz-se necessário um diálogo a respeito da escola inclusiva atual na busca de uma escola instrumentalizada, de um corpo docente preparado com linguagem, conceitos, valores e perspectiva do ensino no presente.

As discussões que circundam as temáticas de gênero, racismo/antirracismo e saúde têm alcançado grandes proporções no século XXI, uma vez que o intenso crescimento do preconceito, dos discursos de ódio e da disseminação de notícias falsas têm intensificado a desigualdade, racismo e misoginia. Debates se fazem cada vez mais necessários e a divulgação científica tem sido essencial, popularizando o conhecimento científico e favorecendo o bem-estar da sociedade e o combate à violência. Esta pesquisa-ação avalia o potencial da mesa-redonda: “Entre o Biológico e o Social: tecnologias de gênero, racismo/antirracismo e saúde” na desmistificação de conceitos embasados no determinismo biológico, favorecendo um ensino mais plural e humano. Realizado em 17 de junho de 2021 pelo projeto de extensão “Evolução Para Todos” em modalidade online, o evento contou com duas convidadas que apresentaram a relevância destas temáticas com base nas vivências e pesquisas realizadas por elas, para um público de diferentes formações e localidades. O evento proporcionou conhecimento e reflexão mais aprofundada das temáticas, e evidenciou como a divulgação científica é uma aliada essencial na construção de uma sociedade mais consciente e humanizada.

As crianças nem sempre foram alvos de cuidado e proteção, pois antes se tinha a ideia de que os pequenos seres humanos eram adultos em miniatura. No entanto, a história da humanidade é mercada por transformações que impactam no modo de pensar e agir na sociedade, o que leva a mudanças no modo de vida dos indivíduos. Dessa forma, transitamos de uma concepção em que adultos e crianças não tinha diferença para o entendimento das necessidades específicas que esta etapa da vida apresenta. Inclusive, compreendendo a importância de uma instituição fora do âmbito familiar para o atendimento dos indivíduos na etapa da infância. Assim, a partir de uma abordagem qualitativa, este texto tem por objetivo apresentar uma análise do surgimento da ideia de infância, das instituições de Educação Infantil no Brasil e as transformações que levaram o atendimento a partir de concepção assistencialista até o entendimento da criança como cidadã e o acesso as instituições como um direito. Por fim, consideramos que mesmo com inúmeros avanços na atualidade a Educação Infantil, instituída como direito, ainda carrega alguns desafios a serem superados.

Propomos, por meio deste artigo, analisar a inserção da mulher no processo do ensino, bem como, refletir sobre dinamização e popularização das políticas públicas de ensino superior direcionadas para as Ciências Exatas. Optamos por uma abordagem de caráter qualitativo, tendo como base a pesquisa bibliográfica e principais interlocutores Simone de Beauvoir (1980), Radl-Philpp (2008; 2010; 2013)  e Louro (2007; 2001), além de recorrermos aos bancos de dados do CNPq (Conselho Nacional de Desenvolvimento Científico e Tecnológico) dentre outros recursos tecnológicos para identificarmos a participação de homens e mulheres nos programas de oferecimento de recursos para bolsistas de pesquisas nas áreas das Ciências Exatas. Percebemos que só por meio de incentivo aos estudos na área de exatas poderemos superar o processo de segregação existente entre homens e mulheres. Os construtos biológicos e sociais traçados pela sociedade evidenciam um processo de exclusão vivenciado pela mulher. As políticas e os programas estabelecidos pelo governo e pelas instituições de ensino e pesquisa podem contribuir significativamente para a redução da exclusão social da mulher.

O debate de gênero e sexualidade tem evidenciado as inquietações vivenciadas em diversos segmentos e contextos socioculturais.  O processo de desenvolvimento de falas integra a construção constante e metamorfoseada dos conceitos e identidades relacionadas com o gênero e os e papeis sexuais e sociais de acordo com as representações dos corpos. Desta forma, a articulação dos estudos de gênero deve proporcionar diversas abordagens associando-se a outras categorias de análises presentes no tempo e espaço como classe, etnia, raça e gerações, bem como movimentos socioculturais. Trata-se de um dossiê que tem como tema central gênero, sexualidade e diversidade, apresentando abordagens e contextos socioculturais transitando pelos movimentos feministas e LGBTQI+, violência contra a mulher, formação de identidades sexuais e de gênero, desigualdade de gênero, modelos binários e heteroformativos estabelecidos em nossa sociedade.

Objetivou-se averiguar os impactos da pandemia do novo coronavírus e relacioná-los com o tipo de instituição e a renda familiar dos estudantes de ensino superior do Ceará, Brasil. Estudo exploratório, descritivo, de abordagem transversal, realizado entre junho e setembro de 2020, com a participação de 3.691 estudantes do ensino superior do Ceará. Para coleta de dados, utilizaram-se de questionário sociodemográfico e do Inventário de Saúde Mental (MHI-38). Os resultados constataram que os acadêmicos de instituições privadas possuem melhores índices de saúde mental em todas as dimensões do MHI-38. A partir da análise das maiores instituições presentes na pesquisa, constatou-se que os alunos da Universidade Federal do Ceará, assim como os da Universidade Estadual do Ceará, detiveram as menores pontuações, implicando maiores influências psicológicas. Renda e índices de saúde mental possuem relação direta de proporcionalidade. Deste modo, conclui-se que a saúde mental dos estudantes de ensino superior do Ceará foi influenciada conforme a instituição a qual fazem parte e as condições de renda. Logo, compete às entidades de ensino o estabelecimento de redes de apoio para promoção e assistência em saúde mental ao público acadêmico.

ABSTRACT. The major challenges in road infrastructure studies are related to the evaluation of the road pavement quality in a practical, non-destructive, and low-cost way. Information about the thickness of the layers is fundamental to pavement repairing. In this study, the applicability of the ground penetrating radar (GPR) method in the delimitation of the pavement layer is tested at the Shallow Geophysical Test Site Applied to Engineering of Universidade Estadual de Goiás (UEG). The ground penetrating radar presents satisfactory results, identifying the top and bottom of the first five layers by the 270, 400, and 900 MHz antennas. The 2 GHz antenna was able to only delimit the top and bottom of the Hot Rolled Asphalt (HRA). The geomembrane with geotextile set and the concrete layer were not identified in the radargrams. The resolution of each antenna is 9.8 cm for 270 MHz; 6.0 cm for 400 MHz; 2.9 for 900 MHz; and 1.6 cm for 1600 MHz. Concerning layer thickness estimates, the antennas had an efficiency percentage of 83 % (270 and 1600 MHz), 83.29 % (400 MHz), and 84.40 % (900 MHz). Layer thickness estimates obtained by GPR antennas were compared with true thickness using a paired t-test (α= 0.05). No significant differences in layer thickness were observed for the GPR antennas versus the actual pavement thickness.Keywords: GPR; geosynthetics; road investigation; shallow geophysical test site; non-destructive testing.
Seismic evidences of recurrent volcanism across the North Brazilian and the Fernando de Noronha ridges – Brazilian Equatorial Atlantic Ocean

ABSTRACT. This study, based on the interpretation of LEPLAC (the Brazilian Continental Shelf Survey Project) deep seismic lines (~16.0 s twtt), reveals for the first time across the Brazilian Equatorial Atlantic Ocean seismic evidences that buried portions of individual volcanic edifices of the North Brazilian and the Fernando de Noronha volcanic ridges are laterally coupled with a series of volcanic wedges. Our analyses evidence that these magmatic occurrences are presented as layered volcanic bodies as wide as 80 km and as thick as 1.2 s (twtt) close to the volcanic edifices. Volcanic wedges occur as layered prograding bodies stemming directly from the major volcanic edifices of both ridges. Seismic analyses also reveal that numerous layered volcanic accumulations associated to a same individual volcanic edifice may occur along variable stratigraphic levels. These occurrences indicate that the evolution of the North Brazilian and the Fernando de Noronha volcanic ridges is followed by a long history of recurrent volcanic activities that may have possibly been synchronous in distinct volcanic edifices distant apart.Keywords: seamounts, guyots, volcanic seismic facies, volcanostratigraphy, intraplate volcanic ridges.
