Time-averaged flow characterisations in a bimodal gravel-bed stream and relative role of sediment depositions on near-bed coherent flow structures
Authors: Das Ratul , Malakar Pritam , Datta Akash
Published: February 2024

The present study aims to quantify experimentally the relative role of sediment depositions on near-bed flows and turbulence in a gravel-bed stream. Time-averaged velocity was measured over a sand-filled gravel-bed stream with four cases of sediment depositions and compared with those over a gravel-bed stream without sediment depositions. An acoustic Doppler velocimeter was used to measure the instantaneous velocity of flows. The progressive infilling of void spaces in the gravel-bed stream forms distinct bimodal depositions that alter the mean flows characterised by increasing zero-velocity levels and massive damping in the bed shear stresses. The data plots of turbulent intensity depict enhancement of streamwise turbulent intensity in the near-bed flow region with increasing sand depositions. Moreover, the opposite nature of streamwise and vertical turbulent kinetic energy fluxes in the interfacial sublayer leads to slowing down the time-average Reynolds shear stresses at the vicinity of the gravel-bed surface. At the vicinity of the crest, the ejection and sweep events contributed approximately 86 and 56%, respectively, to the total Reynolds shear stress production in the case of gravel bed under clear-water flow conditions. By contrast, the contributions of turbulent sweep events increased over the sand-filled gravel bed at the same location.

Published: February 2024

Este artigo trata da produção discursiva em torno do lançamento de uma coleção de moda, intitulada “Carne Seca ou um Turista Aprendiz em Terra Áspera”, do estilista brasileiro Ronaldo Fraga, com o objetivo de analisar e discutir os sentidos sobre os sertões que circulam na internet na contemporaneidade, considerando sua inscrição no universo midiático nacional. Como metodologia, selecionamos matérias publicadas em sites na internet, onde as notícias sobre o evento circularam, e os submetemos à análise dos discursos que produziram sentidos sobre o que é o sertão e o sertanejo. Consideramos, portanto, que os estudos do discurso nos permitem reflexões sobre a construção de saberes, sentidos e “verdades” na/pela história. Para tanto, destacamos como respaldo teórico-metodológico os pressupostos da Análise do Discurso de orientação francesa e os estudos de Michel Foucault sobre discursos, sujeitos e saberes, além de referenciais teóricos sobre a historiografia do sertões, sobretudo, no que se refere à etimologia da palavra, o surgimento e as transformações do conceito ao longo da história. Em linhas gerais, nossas análises sobre as matérias apontam para efeitos de sentido sobre um sertão “áspero”, “masculino”, passível de refinamento, ao passo em que esses discursos constroem a figura do estilista como um sujeito capaz de transformar essa aspereza em moda.

A Fundamentação teórica no que diz respeito ao gênero apoia-se em Garcia (2015), Tiburi (2018), Felipe (2016) e Lugones (2014). A pesquisa com viés documental baseia-se em fontes da Universidade, como Regimento, PDI, Estatuto, visando à compreensão dos parâmetros norteadores desses cargos institucionais. Nessa perspectiva, a investigação destaca uma desigualdade, que favorece o gênero masculino, quando se trata de cargos indicados. Um outro fator importante diz respeito à formação das mulheres que, de uma maneira geral, apresentam maior titulação (doutorado, mestrado e especialização).
CONSTRUÇÃO REFERENCIAL DA NÃO-PESSOA NOS ENUNCIADOS NO FACEBOOK
Authors: Cordeiro Ana Luiza
Published: February 2024

Os interlocutores estabelecem trocas interacionais mobilizando a língua para se constituírem como sujeitos linguística e empiricamente. Para tanto, a referenciação de pessoa, espaço e tempo é imprescindível para localizar o locutor em sua centralidade enunciativa e, consequentemente, construir as referências para os alocutários. Nesse sentido, parte-se da discussão da linguística enunciativista para analisar uma postagem coletada na fanpage #Meu Amigo Secreto no Facebook, bem como suas replicações por usuárias da rede social, visando identificar se há variantes de referenciação da terceira pessoa num mesmo enunciado diante da mudança do sujeito locutor. Com ancoragem teórica da Teoria da Enunciação, de Émile Benveniste (2005; 2006), com especial enfoque no estudo Da Subjetividade na Linguagem, publicado em Problemas de Linguística Geral I (2005), acredita-se haver o atravessamento do locutor enquanto “Eu” que determina ou indica a classificação da não pessoa enquanto específica ou genérica.

Published: February 2024

A contribuição dos gêneros textuais é notória em nossa vida desde a infância. Dentre os diversos existentes, destacamos o jornalístico, o qual está presente em nosso cotidiano através de notícias em diferentes suportes. Com o cenário de pandemia, desde o ano de 2020, o vírus SARS-CoV-2, responsável pela COVID-19, foi tema recorrente nas manchetes. Consequentemente, com o avanço da doença, surgiu a necessidade da imunização e, posteriormente, a obrigatoriedade do “Passaporte da Vacina” expandiu-se. Esta pesquisa é voltada para a análise e reflexão das publicações de notícias sobre o “Passaporte da Vacina” e o emprego das “anáforas diretas” nos textos midiáticos. Logo, foram selecionadas duas notícias: uma do site CNN e outra do EL PAÍS. O método descritivo e quantitativo buscou observar e refletir se as notícias tencionam influenciar os leitores na tomada de decisão para realizar o esquema vacinal (imunização de pelo menos duas doses da vacina), e apresentar o “Passaporte da Vacina” quando for solicitado. As análises nos permitiram observar os textos e o processo coesivo nas relações linguísticas através de pronomes, advérbios, emprego de conectivos, sinônimos, expressões nominais, dentre outros recursos indispensáveis na compreensão do gênero.

Published: February 2024

O presente artigo busca relacionar, com base em pesquisa qualitativa e análise documental e teórica, o grafite urbano como expressão de arte popular e o seu respectivo apagamento e destruição como expressão do discurso autoritário. Analisando decisões institucionais e ações do governo de São Paulo, sob a gestão do prefeito João Doria, objetiva-se compreender como essa manifestação se mostra antidemocrática e antipopular, por meio de Análise Crítica de Discurso (ACD) interdisciplinar. Para se chegar ao resultado do estudo aqui apresentado, utilizou-se a concepção teórica de grafite como expressão artística e conceituações de fascismo, bem como sua relação para com a arte, em cada governo autoritário exemplificado. Conclui-se, após realização da análise, que o ato de apagamento do grafite e o discurso que o sustenta são manifestações ur-fascistas, com base no conceito de Umberto Eco e de referenciais teóricos fornecidos por autores como van Dijk e Maingueneau.
Dialogismo em cartaz
Authors: Da Silva Maria Laura
Published: February 2024

Pretende-se, no presente artigo, realizar uma análise do gênero cartaz, utilizado em uma manifestação a favor da educação e contrária a mudanças e cortes de recursos feitos pelo atual governo, ocorridas no mês de maio de 2019. Nesse sentido, situado no campo da Linguística Aplicada, o intuito desse trabalho é investigar como os discursos articulam-se nos cartazes, levando em consideração o dialogismo bakhtiniano, e como eles podem contribuir para o letramento crítico. Em face disso, o trabalho fundamenta-se na concepção de Dialogismo (BAKHTIN; 2000, 2016), no conceito de Letramentos Críticos (KLEIMAN, 1995; ANDRADE, 2016; SANTOS, 2016) e na Educação Crítica (FREIRE & SHOR, 2008). Metodologicamente, o corpus da análise foi constituído por cartazes usados durante manifestações na cidade do Natal-RN. Para explicitar as relações dialógicas envolvidas na produção desses discursos, analisamos também algumas matérias da esfera jornalística que vincularam informações que dialogam com os enunciados dos cartazes. Como resultados, constatamos que as relações dialógicas, construídas por meio dos cartazes analisados, foram estabelecidas por meio de retomadas e ressignificações de termos como “fake news” e “mito”. Tais ressignificações só foram possíveis a partir de uma postura crítica dos interlocutores que produziram e expuseram seus cartazes no contexto da manifestação.
GÊNERO, SEXUALIDADE E RELAÇÕES DE PODER
Authors: De Oliveira Dantas Crislainny Dayanny
Published: February 2024

A temática do gênero e sexualidade se mostra cada vez mais relevante, considerando o fortalecimento dos espaços de luta e resistência na atualidade. A escola, enquanto instituição que exerce controle sobre os corpos através da disciplinarização, deve estar atenta à essas questões e promover oportunidades iguais para os mais diversos estudantes. Sob essa perspectiva, este artigo tem como objetivo analisar o discurso produzido no Referencial Curricular do Ensino Médio Potiguar, no tocante à temática do gênero e sexualidade, como um dos Temas Contemporâneos Transversais, relacionando as relações de poder na construção dos sentidos e das vontades de verdade. Para tanto, utilizamos a Análise do Discurso como aporte teórico a partir dos estudos de Foucault (1988, 1995, 1998, 2004, 2008). Trata-se de um trabalho descritivo-interpretativo de caráter qualitativo. Usamos o método arqueogenelógico para análise do discurso que tem como corpus enunciados extraídos do Referencial Curricular do Ensino Médio Potiguar, documento normativo que orienta a práxis didático-pedagógica, formulado a partir da reforma do Ensino Médio. A análise nos permitiu constatar que a temática emerge nos Temas Contemporâneos Transversais do documento como estratégias de biopoder e regulamentação dos temas que envolvem à sexualidade no contexto escolar.

Published: February 2024

Neste trabalho, a partir de uma abordagem qualitativa, examinamos vinte e oito textos falaciosos disponibilizados no site Aosfatos.org e relacionados aos resultados das eleições presidenciais brasileiras de 2022. Nossos objetivos foram: i) localizar as estratégias interacionais, textuais e cognitivas mais recorrentes em conjuntos de Fake News e examinar papel argumentativo dessas produções; ii) descrever como se operacionalizam os textos em movimentações sociais digitais. Teoricamente, embasamo-nos em Perelman e Olbrechts-Tyteca (1996 [1958]), entre outros, no que diz respeito às Teorias da Argumentação e procedemos a um diálogo com estudos do texto-discurso de van Dijk e Kintsch (1983), Koch (1996), Marcuschi (2007), Morato e Bentes (2013), entre outros. Os resultados apontam para a estratégia de repetição como central, a qual foi fortalecida pela lógica das redes digitais e pelo cenário de polarização política da época. Além disso, do ponto de vista argumentativo, as Fake News precisam ser examinadas em agrupamento de textos-discursos, pois esse conjunto e a dinâmica das redes podem indicar como ocorre a força argumentativa dessas produções.

combined with Texture Analysis in Predicting the Histological Grades of Rectal
Adenocarcinoma
Authors: Gao Fei , Zhou Jie , Cao Wuteng , Gong Jiaying , Wang Peipei , Wang Chuanbin , Fang Xin , Zhou Zhiyang
Published: February 2024

Purpose::

To evaluate the predictive value of 3.0T MRI Intravoxel Incoherent motion diffusion-weighted magnetic resonance imaging (IVIM-DWI)
combined with texture analysis (TA) in the histological grade of rectal adenocarcinoma.

Methods::

Seventy-one patients with rectal adenocarcinoma confirmed by pathology after surgical resection were collected retrospectively. According to
pathology, they were divided into a poorly differentiated group (n=23) and a moderately differentiated group (n=48). The IVIM-DWI parameters
and TA characteristics of the two groups were compared, and a prediction model was constructed by multivariate logistic regression analysis. ROC
curves were plotted for each individual and combined parameter.

Results::

There were statistically significant differences in D and D* values between the two groups (P < 0.05). The three texture parameters
SmallAreaEmphasis, Median, and Maximum had statistically significant differences between groups (P = 0.01, 0.004, 0.009, respectively). The
logistic regression prediction model showed that D*, the median, and the maximum value were significant independent predictors, and the AUC of
the regression prediction model was 0.860, which was significantly higher than other single parameters.

Conclusion::

3.0T MRI IVIM-DWI parameters combined with TA can provide valuable information for predicting the histological grades of rectal
adenocarcinoma one week before the operation.
A Systematic Review and Meta-Analysis of MRI Radiomics for Predicting
Microvascular Invasion in Patients with Hepatocellular Carcinoma
Authors: Zhou Hai-ying , Cheng Jin-mei , Chen Tian-wu , Zhang Xiao-ming , Ou Jing , Cao Jin-ming , Li Hong-jun
Published: February 2024

Background::

The prediction power of MRI radiomics for microvascular invasion (MVI) in patients with hepatocellular carcinoma (HCC) remains uncertain.

Objective::

To investigate the prediction performance of MRI radiomics for MVI in HCC.

Methods::

Original studies focusing on preoperative prediction performance of MRI radiomics for MVI in HCC, were systematically searched from databases
of PubMed, Embase, Web of Science and Cochrane Library. Radiomics quality score (RQS) and risk of bias of involved studies were evaluated.
Meta-analysis was carried out to demonstrate the value of MRI radiomics for MVI prediction in HCC. Influencing factors of the prediction
performance of MRI radiomics were identified by subgroup analyses.

Results::

13 studies classified as type 2a or above according to the Transparent Reporting of a Multivariable Prediction Model for Individual Prognosis or
Diagnosis statement were eligible for this systematic review and meta-analysis. The studies achieved an average RQS of 14 (ranging from 11 to
17), accounting for 38.9% of the total points. MRI radiomics achieved a pooled sensitivity of 0.82 (95%CI: 0.78 – 0.86), specificity of 0.79
(95%CI: 0.76 – 0.83) and area under the summary receiver operator characteristic curve (AUC) of 0.88 (95%CI: 0.84 – 0.91) to predict MVI in
HCC. Radiomics models combined with clinical features achieved superior performances compared to models without the combination (AUC:
0.90 vs 0.85, P < 0.05).

Conclusion::

MRI radiomics has the potential for preoperative prediction of MVI in HCC. Further studies with high methodological quality should be designed
to improve the reliability and reproducibility of the radiomics models for clinical application.
MRI Plain Scan: A Tool in the Management of Cervical Cancer during
Pregnancy
Authors: Gao Feng , Qian Ting , Sun Minghua , Lu Yuanyuan , Cheng Jiejun , Fu Le
Published: February 2024

Objective::

The purpose of this study was to assess the diagnostic value of magnetic resonance imaging (MRI) in staging and treatment of cervical cancer in
pregnancy, and to evaluate the benefit of apparent diffusion coefficient (ADC) during neoadjuvant chemotherapy management.

Materials and Methods::

This was a retrospective cohort study. Patients were divided into two groups according to the stage of cervical cancer. The mean term of pregnancy
at the time of the diagnosis was the early second trimester (range 10-27 weeks) and the median age was 33 years (range 26-40 years). The
abdominal and pelvic MRI images and clinical data of these patients were reviewed. Tumor size, local tumor spread, and nodal involvement were
evaluated using an MRI dataset. The treatment and follow-up imaging were analyzed as well, and the ADC was measured before and after the
chemotherapy.

Results::

16 patients with histopathologically confirmed cervical cancer during pregnancy were retrospectively enrolled. 7 patients were diagnosed with
local cervical cancer (FIGO stage IAI) and designated as early stage group, as the lesion was invisible on MRI. In this group, pregnancies were
allowed to continue until cesarean delivery (CD) at 38-41 weeks. The other 9 patients presenting with local or extensive cervical cancer (FIGO
stage IB2-IIA2) were designated as the advanced-stage group. The lesion could be measured and analyzed on MRI. They were treated with neoadjuvant
chemotherapy in pregnancy. Among them, 6 patients underwent TP regimen (paclitaxel 135~175 mg/m2 plus cisplatin 70~75 mg/m2),
while 3 patients received TC regimen (paclitaxel 135~175 mg/m2 plus carboplatin AUC=5). NACT was performed for 1 to 2 courses before
surgery. ADC demonstrated significant differences before and after chemotherapy administered during pregnancy (1.06 0.12 sec/mm2 vs. 1.34
0.21 sec/mm2).

Conclusion::

MRI has been found to be helpful in staging cervical cancer in pregnancy. Patients with stage IA confirmed by MRI can choose conservative
treatment and continue the pregnancy until term birth. MRI can dynamically monitor the efficacy of chemotherapy for patients with stage IB and
above during pregnancy. ADC value can have a potential role in the evaluation of chemotherapy efficacy
Immunoglobulin G4 (IgG4)-related Lymphadenopathy in Submandibular Space
Mimicking Submandibular Malignant Tumor: A Case Report
Authors: Yang Go Eun
Published: February 2024

Background::

Immunoglobulin G4 (Ig G4)-related disease is rare; however, it is a fibroinflammatory disease that has been studied a lot so far. Although the
expression pattern varies depending on the organ affected, it usually manifests as organ hypertrophy and organ dysfunction.

Case Presentation::

A 46-year-old man was referred to our otorhinolaryngology department for left submandibular swelling and tenderness that occurred 2 weeks ago.
He was treated with antibiotics (augmentin 625mg, per oral) for 2 weeks, but his symptoms did not improve, and his white blood cell (WBC) count
was 10,500 /μL (normal 3,800−10,000 /μL).

Conclusion::

A mass-like lesion of the submandibular space has been concluded and the laboratory findings have been satisfactory (IgG4 level); IgG4-related
disease, which is rare, but recently often reported, can be included in the differential diagnosis.

Authors: Çavdarlı Cemal , Güvenç Hülya , Çomçalı Sebile , Coşkun Çiğdem , Alp Mehmet Numan
Published: February 2024

Background::

Immune thrombocytopenic purpura (ITP) is a rare auto-antibody mediated disease of isolated thrombocytopenia (<100,000/μL) with normal
haemoglobin levels and leukocyte counts. Only a small number of ITP cases have been reported with accompanying ophthalmological findings.
Herein, we report an ITP case with demonstrative retinal haemorrhages.

Case Presentation::

A fifty-five-year-old woman with a known history of type 2 diabetes mellitus was referred to our clinic with blurred vision. After detailed
anamnesis and clinical assessment, she was diagnosed as primary ITP in haematology department, and systemic steroid (1.5mg/kg) therapy was
initiated. During her follow-up, a concomitant peripheral facial paralysis (PFP) emerged. In the course of follow-up, her platelet counts increased
gradually, the retinal haemorrhages regressed partially, and the PFP recovered completely.

Conclusion::

ITP is a rare haematologic disease that sometimes manifests with additional systemic involvements, and this disease should be remembered in the
differential diagnosis of unusual retinal haemorrhages, which might be the only presenting feature.
Primary Pulmonary Enteric Adenocarcinoma: Rare Imaging Findings
Authors: Xie Lixuan , Liu Zhijun , Chen Yousan
Published: February 2024

Introduction::

Pulmonary enteric adenocarcinoma (PEAC) is an extremely rare variant of lung adenocarcinoma characterized by pathological features similar to
those of colorectal adenocarcinoma. It is mostly observed on computed tomography (CT) and positron emission tomography (PET)/CT as solitary
or multiple nodules/masses in the lung. It tends to grow rapidly and is difficult to distinguish from lung metastatic colorectal cancer. Herein, we
have presented a case of PEAC with special imaging findings.

Case Presentation::

A chest CT scan of a 72-year-old man with suspected chronic pneumonia revealed a well-defined consolidation in the upper lobe of the left lung.
The lesion was slightly enlarged at the 9-month follow-up, and low FDG accumulation was subsequently observed using 18F-fluorodeoxyglucose
(18F-FDG) PET/CT scans. The patient was later diagnosed with PEAC through percutaneous lung biopsy.

Conclusion::

Our case has demonstrated specific imaging findings of PEAC.
Iatrogenic Pseudoaneurysm with Acute Arterial Thrombosis in Multiple
Branches of the Lower Limbs Treated by Ultrasound-guided Thrombin
Injection: A Case Report
Authors: Gou Bo , Tu Bin , Xin Feng-Yue , Zhang Ji-Cheng , Wang Jie , Liu Jian
Published: February 2024

Introduction::

With the development of vascular intervention, pseudoaneurysm complications are increasing. Ultrasound-guided thrombin injection (UGTI) is
currently the treatment of choice for pseudoaneurysm, but the pharmacological properties of thrombin may trigger acute thrombosis within the
vessel lumen. Despite a very low incidence, this type of primary arterial thrombosis is a serious complication of UGTI, and cases involving
multiple branches of the lower limb arteries are particularly rare.

Case Presentation::

Here, we report a case of a 65-year-old male who underwent UGTI for the treatment of an iatrogenic pseudoaneurysm of the femoral artery
complicated by acute thrombosis of multiple arteries in the lower limbs, and the patient ultimately underwent a successful thrombectomy.

Conclusion::

We reviewed the case and analyzed the possible etiologic causes, providing a reference for future clinical work.

Supporting data were obtained through interviews with students, lecturers, laboratory assistants, and laboratory personnel representatives. The results showed that the implementation of biochemistry lab work at the University in Mataram had gone through the pre-laboratory, laboratory work, and post-laboratory stages. Expository, inquiry, and demonstration are lab work methods, with 80% of the implementation using the expository method. Instructions related to waste handling have not been carried out in the implementation of biochemistry lab work. Based on these findings, several recommendations were put forward for improving the biochemistry lab work at the University.
Effectiveness of discovery learning-based multiple representation module on enhancing the critical thinking skills of the students with high and low science process skills
Authors: Chusni Muhammad Minan
Published: February 2024

The study examines the effectiveness of a multiple representation module based on discovery learning in enhancing students' critical thinking. The study used a quasi-experiment design with a 2×2 design analysis. The subjects were 114 students with high and low science process skills from Sleman district's class VII Islamic Junior High Schools. The sample was separated into two groups: a control group that utilized conventional modules and an experimental group that utilized a Discovery Learning-based Multiple Representation module; each sample group was further broken into two groups with high and low science process skills. The test of critical thinking skills was adopted by Facione (2011). Another instrument was an observation sheet to observe science process abilities. The data analysis revealed that implementing the Discovery Learning-based Multiple Representation modules improved students' critical thinking abilities. Not only did student science process abilities influence their critical thinking abilities, but there was also an interaction between the module and student science process abilities.
A Review of North American Prospects for Power and Hot-Water Generation with Thermal Energy
Authors: Benavides Jose , Sharma Pushpesh , Al Saedi Ahmed , Kabir Shah
Published: February 2024

This article outlines an innovative approach to explore thermal energy extraction for power generation or industrial hot water applications. Unlike traditional steady-state models, this approach embraces time-variant scenarios, explicitly incorporating a cyclical fluid circulation strategy to maintain a stable surface fluid temperature or power output. By introducing an increasing and decreasing stepwise rate sequence and an intermittent circulation strategy, the method aims to optimize efficiency in response to varying geothermal gradients. This approach also considers the effect of well configurations namely U-shaped heat exchangers, and conventional wellbore heat exchangers. The study emphasizes the importance of assessing the value proposition of this rate-sequencing approach in different North American basins, with the potential for replication in other regions. This approach recognizes the geographic dependency of thermal prospects, particularly at specific well depths. Notably, the article explores the possibility of retrofitting abandoned wells in oil fields and drilling new wells in geothermal-friendly areas for a comparative analysis of their relative value propositions. In essence, the proposed roadmap signifies a departure from traditional models, showcasing a dynamic and adaptable strategy for thermal energy extraction. This strategy aligns with the need for energy transition and changing energy mix for the future. The inclusion of retrofitting existing wells and drilling in strategic locations adds a practical dimension to the study, offering insights into the scalability and applicability of the proposed approach beyond its initial geographic focus.

El objetivo de este estudio es evaluar y valorar la adopción e impacto económico, social y ambiental de las tecnologías generadas para el manejo de los suelos en el sistema de producción de algodón en el Valle Cálido del Alto Magdalena. Se identificaron las principales tecnologías en manejo de suelos, las cuales se dividen principalmente en la labranza convencional, mínima, cero y vertical. Se encontraron unas tasas de adopción de 80.5% en la labranza convencional, seguido por la labranza mínima, con una participación del 13%, la labranza cero con un 3,6%, y finalmente la labranza vertical con un 2,9% de adopción. Adicionalmente se identificaron algunos elementos endógenos y exógenos que dinamizan o inhiben el proceso de adopción, como la disponibilidad de maquinaria, la tenencia de la tierra, incidencia de malezas, menores costos en la preparación del suelo entre otros factores. Otro elemento a evaluar fue el medio de información más efectivo de difusión de las tecnologías en labranza de suelos, el cual resulta ser la trasmisión del conocimiento a través de la familia y la técnica más efectiva es la demostración de métodos (55,1%). Las tasas de adopción se atribuyen principalmente a la aversión al riesgo por parte de los agricultores por cuanto creen que los métodos diferentes a los convencionales facilitan la proliferación de malezas trayendo consigo bajas en los rendimientos y por otro lado la ineficacia de los métodos de difusión.

Published: February 2024

Background

Respiratory diseases, including active tuberculosis (TB), asthma, and chronic obstructive pulmonary disease (COPD), constitute substantial global health challenges, necessitating timely and accurate diagnosis for effective treatment and management.

Objective

This research seeks to develop and evaluate a noninvasive user-friendly artificial intelligence (AI)–powered cough audio classifier for detecting these respiratory conditions in rural Tanzania.

Methods

This is a nonexperimental cross-sectional research with the primary objective of collection and analysis of cough sounds from patients with active TB, asthma, and COPD in outpatient clinics to generate and evaluate a noninvasive cough audio classifier. Specialized cough sound recording devices, designed to be nonintrusive and user-friendly, will facilitate the collection of diverse cough sound samples from patients attending outpatient clinics in 20 health care facilities in the Shinyanga region. The collected cough sound data will undergo rigorous analysis, using advanced AI signal processing and machine learning techniques. By comparing acoustic features and patterns associated with TB, asthma, and COPD, a robust algorithm capable of automated disease discrimination will be generated facilitating the development of a smartphone-based cough sound classifier. The classifier will be evaluated against the calculated reference standards including clinical assessments, sputum smear, GeneXpert, chest x-ray, culture and sensitivity, spirometry and peak expiratory flow, and sensitivity and predictive values.

By integrating this technology into medical education and practice, healthcare professionals can stay up-to-date with the latest developments, improve patient outcomes, and drive innovation in the field.

OBJECTIVE

The objective of this study is to examine the student's views regarding the utilization of ChatGPT for educational purposes in the United Arab Emirates.

METHODS

The theoretical framework involves the adoption properties, including the trialability, observability, compatibility, users’ satisfaction, personal innovativeness, and Technology Acceptance Model (TAM) constructs. The uniqueness of this paper lies in its theoretical model which connects both individual-based characteristics and technology-based aspects. The originality of the study lies in its theoretical framework which combines both individual-based characteristics and technological features. Furthermore, a unique hybrid analysis method will be applied, combining deep learning-based structural equation modeling (SEM) and artificial neural network (ANN) analysis. Additionally, the study employs the Importance-Performance Map Analysis (IPMA) to assess the impact and performance of the various factors.

RESULTS

The results of the ANN and IPMA analysis indicated that Perceived Usefulness (PU) is a critical predictor of Users' Intention to Use the ChatGPT.

CONCLUSIONS

This finding is significant as it helps decision-makers in the educational sector to prioritize their efforts and plans based on the relative significance of each factor. The study also has important methodological implications, demonstrating the potential of deep artificial neural network (ANN) architecture to provide a deeper understanding of the complex relationships among the factors in a theoretical model.

Application of Building Intelligent Design in Energy Saving and Sustainable Development
Authors: Luo Jiarui
Published: February 2024

With the rapid development of social and economic development, people's living standards to a certain extent has been continuously improved, building energy consumption further shows a trend of sustained growth, the apparent contradiction in the supply of energy resources in our country further aggravated. In order to the sustainable development of mankind, we must effectively reduce the energy consumption, and further implement the building energy conservation measures into practice. To a certain extent, effective control of building energy consumption, and further alleviate the contradiction between China's energy supply and economic and social development. Let building energy-saving design in China's energy saving and emission reduction to make the necessary contribution. China is a populous country, per capita resources are poor, people's overall average standard of living is low. With the deepening of China's reform and opening up, the Chinese people are gradually getting richer and richer, the Chinese people began to continuously improve their material life, especially the living environment, so China's construction business is also rapidly developing, with the increase of a large number of new buildings, the building energy consumption is growing rapidly. However, China's large population, the energy situation is not optimistic, reduce building energy consumption is the implementation of the scientific concept of development, to achieve sustainable development of the major strategic initiatives.
Crisis sociocomerciales en la industria textil de México (1519-2022)
Authors: Gómez Pérez Ana Laura
Published: February 2024

La historia textil mexicana se entreteje con acontecimientos sociales y comerciales que marcaron su desarrollo y crecimiento nacional, a través de los cuales ha experimentado varias crisis. El objetivo de esta investigación es analizar las causas que provocaron las cinco crisis sociocomerciales en la industria textil mexicana de 1519 a 2022, mediante una metodología lógico histórico, pues sus procedimientos y herramientas cronológicas permiten examinar hechos pasados usando una historiografía de fenómenos reales. Por ello, la revisión se enfoca en que las cuestiones sociales y comerciales fueron el eje principal para que las cinco crisis marcaran el rumbo de este sector, ya que lo textil ha sido esencial para la economía, pues una política nacional proteccionista fortalecedora contribuyó a que el sector textil del siglo XVI siguiera de pie, mientras que la reducción de costos y el desempleo fueron consecuencias de una sobreproducción del siglo XX.
Derechos humanos de las mujeres en prisión, un anhelo
Authors: Gutiérrez Domínguez Ana María
Published: February 2024

En este ensayo se reflexiona sobre los derechos humanos de las mujeres en prisión, desde un enfoque jurídico y de política criminal, con el fin de evidenciar su ineficacia. Se analiza la situación de las mujeres en dos momentos, como sujetas del procedimiento penal y como internas en centros de reclusión. Para ello se parte de datos estadísticos que aportan un panorama de sus circunstancias y permiten establecer las formas en las que se vulneran sus derechos. Se concluye con las siguientes propuestas: en primer lugar, elaborar un protocolo en el procedimiento penal para tratar a las mujeres con perspectiva de género y eliminar la prisión preventiva oficiosa; en segundo, generar un instrumento que dé certeza jurídica a aquellas que se encuentran en prisión. El objetivo primordial es fomentar el reconocimiento y validez de los derechos humanos de las mujeres.
Naturaleza jurídica de la Acción por incumplimiento en Ecuador frente a la ejecución de sentencias internacionales
Authors: López Ruiz Iliana
Published: February 2024

Se valora la garantía constitucional de acción por incumplimiento, presentando un análisis detallado en el ordenamiento jurídico ecuatoriano, asimismo, se profundiza en sus requisitos de procedencia y admisibilidad, con énfasis en la prueba del reclamo previo. Por último, estudia el procedimiento de esta garantía y los efectos de la sentencia derivada de la misma. El objetivo fundamental es analizar la eficacia de esta acción jurisdiccional partiendo del estudio de su naturaleza jurídica. Se utiliza el método cualitativo de investigación científica, para la recolección de información sobre aspectos relacionados a la regulación normativa de esta acción. Finalmente, se logra concluir que no se delimitó adecuadamente en la norma la naturaleza y alcance de esta garantía en lo referente al cumplimiento de sentencias internacionales, pues forzadamente se le da esta doble dimensionalidad a la garantía, sin considerar que exigir el cumplimiento de una sentencia internacional no es igual a exigir el cumplimiento de una norma abstracta o un informe, a ello sumado que la Acción por incumplimiento es un proceso de conocimiento, que posee requisitos de procedencia y admisibilidad, que dificultan el acceso de las víctimas, sometiéndolas a un nuevo proceso, con las etapas y tiempos procesales que ello implica. Es precisamente esa la relevancia de la investigación debido a que por las razones antes mencionadas esta garantía jurisdiccional no está siendo eficaz para exigir el cumplimiento de resoluciones internacionales emitidas por organismos de protección de derechos humanos.
Análisis de las políticas de transformación digital de las microempresas en la región latinoamericana: los casos de Colombia y Chile
Authors: Barcia Lehmann Rodrigo , Martínez-Cárdenas Betty
Published: February 2024

El objeto de este artículo es comprender cuál es la naturaleza y las implicaciones de las políticas de transformación digital de las microempresas en la región latinoamericana, en particular, respecto de los casos de Colombia y Chile. En efecto, debido a la pandemia causada por el virus SARS-CoV-2, que generó la enfermedad COVID-19 y las medidas de restricción de movimiento del año 2020, la transformación digital de las microempresas se hizo aún más urgente. Esta urgencia obedece a la necesidad de reactivar la economía, de un lado, pero también a la necesidad de regular internamente el Objetivo de Desarrollo Sostenible Núm. 9 (ODS9). Para ello, Chile y Colombia han transpuesto en la legislación interna todo un conjunto de políticas que han acelerado el uso de la tecnología. En especial, nos hemos detenido a analizar qué depara el futuro para las pequeñas empresas, o cómo las políticas públicas ayudarían a la incorporación de las nuevas tecnologías y al cumplimiento efectivo del ODS 9.  Nuestra tesis es que para lograr una reglamentación efectiva en la promoción de las tecnologías emergentes para lograr que estas puedan ser utilizadas para reducir los costos de transacción y las externalidades respecto de las pequeñas empresas, la transposición del ODS9 es insuficiente. Este estudio emplea el método del derecho comparado para analizar algunos de los cambios generados en Chile y Colombia con respecto a las pequeñas empresas y analizará críticamente la técnica de transposición de los ODS. Las nuevas tecnologías pueden servir para trabajar legislativa y jurisprudencialmente sobre estas dos fallas de mercado y las consecuencias de ello merecen una reflexión en derecho comparado.
Contribuciones de la policía administrativa para el cumplimiento de los fines del Estado social y democrático de derecho en el ordenamiento territorial
Authors: Vásquez Santamaría Jorge Eduardo
Published: February 2024

A partir de la interrogante ¿qué contribuciones promueve la policía administrativa en el ámbito especial del ordenamiento territorial colombiano y español para cumplir con los fines que le son asignados en el Estado social y democrático de derecho (ESDD)? primero se hace una contextualización del ESDD, y en él, de los retos a los que está llamado el derecho administrativo para facilitar los cometidos del componente social. De allí se desprende el derecho administrativo como ciencia de dirección, alternativa dogmática que permite diferenciar el ámbito general administrativo de los ámbitos especiales o de referencia, entre los cuales está el ordenamiento territorial. En este opera el ejercicio de la función administrativa que tiene como una de sus expresiones la actuación de policía, lo que da lugar a una exploración comparada del panorama teórico sobre la policía en el derecho administrativo de España y de Colombia, a identificar contribuciones que aquella actuación promueve sobre el ámbito del ordenamiento territorial, y con ellas, de móviles de sistematización en el ámbito administrativo general. Para ello se empleó una metodología cualitativa, dogmático jurídica, comparativo-hermenéutica, con estrategia documental.
