Authors: Tang Yifu , Feng Jinghan
Published: March 2024

Unemployment remains a pervasive challenge on the global stage, bearing significant social, psychological, and economic ramifications. This issue touches the core of human existence, influencing not just the fundamental necessities of life but also personal aspirations and leisure activities. For nations on the cusp of economic growth, like the United States, unemployment is a formidable obstacle to achieving their growth aspirations. Addressing this concern requires a forward-looking approach, where predictions about future unemployment rates are made based on accessible data. This study embarks on such a mission, focusing on the unemployment rates in the United States. It employs the k-nearest neighbor regression (kNNR) to make these estimations. To enhance the precision of these forecasts, we have assembled a new dataset, including factors presumed to impact the behavior of unemployment. Encompassing factors believed to have a bearing on unemployment dynamics. To assess the effectiveness of the kNNR, we have juxtaposed its performance with that of another prominent machine learning contender: linear regression and decision trees. The empirical outcomes are telling with a coefficient of determination (R2 value of 0.936; the kNNR not only showcased its predictive prowess but also outshone the other algorithms in the fray. These findings underscore the potential of the kNNR algorithm as a potent tool in unemployment rate prediction endeavors.

Síndrome de Klinefelter: una revisión integral más allá del cariotipo 47 XXY
Authors: Guevara Márquez Diana Katerine , Méndez García Germán Augusto
Published: March 2024

El síndrome de Klinefelter se define como una condición patológica cuya etiología responde a una aberración cromosómica en el varón cuyo cariotipo característico es el 47 XXY. Con una prevalencia anual entre los 85 y 250 por 100.000 nacidos vivos se considera la patología cromosómica más frecuente. La ausencia de signos clínicos en las primeras décadas de la vida lleva a un diagnóstico tardío asociado a alteraciones metabólicas, vasculares y sobretodo hormonales que impactan de manera negativa en quien padece la condición. En respuesta al infra diagnóstico de esta condición médica se evidencia la necesidad de conocer los procesos genéticos y epigenéticos que explican la aparición de la enfermedad; en aras de cumplir dicho objetivo se realizó una revisión sistemática de la literatura en las principales bases de datos en investigación médica, tras aplicar los criterios de inclusión del material bibliográfico obtenido se filtraron 50 artículos cuyo análisis y consolidación conduce a la elaboración de un documento actualizado y que en virtud de la evidencia científica representa una guía importante en la compresión y abordaje de pacientes con síndrome de Klinefelter.

Praktische wijsheid van de jeugdprofessional ontrafeld: Hoe de professional in het complexe jeugd domein tot handelen komt
Authors: Sarti Asia , Van Zelm Ruben , Egberts Inge , Coppoolse Remco , Houweling Loes
Published: March 2024

SAMENVATTING
Het welbevinden van de Nederlandse jeugd staat onder druk. Jeugdprofessionals die dagelijks werken aan vorming, begeleiding, preventie en behandeling van jonge mensen, zien zich daarin geconfronteerd met de nodige uitdagingen. Aangezien kennis en protocollen ontoereikend zijn in het komen tot adequaat handelen, is het van belang te exploreren wat ‘praktische wijsheid’ van individuele professionals hierin kan betekenen. Data uit acht open interviews, met inzet van de rich pictures methode, zijn geanalyseerd om te onderzoeken wat praktische wijsheid in het jeugddomein behelst. Dit toonde aan dat professionals komen tot het juiste handelen in knellende situaties door het eigen morele kompas als belangrijke richting gever te gebruiken. Het handelingsrepertoire is rijk en loopt uiteen van het volgen van intuïtie en wendbaarheid tot het gebruikmaken van kennis en zelfkennis. Het is van belang dat organisaties ruimte maken voor wat professionals al doen hieromtrent, maar ook dat (gezamenlijke) reflectie wordt gefaciliteerd. Elementen uit onze onderzoeksmethode lijken hierbij behulpzaam te kunnen zijn.

De toekomst van wonen, zorg en ondersteuning verbeelden. Sociaal-ruimtelijk en retrospectief denken als antwoord op institutionele logica’s die op reis gaan. 
Authors: Benoot Toon
Published: March 2024

In deze bijdrage wordt ingegaan op de dominante interpretatie van het begrip de-institutionalisering, waar deze aan heeft bijgedragen, maar ook wat deze niet belicht. Van daaruit wordt gepleit voor een sociaal-ruimtelijk perspectief, en wordt beschreven wat dat kan betekenen in het denken en handelen van sociaal werkers. Daarop wordt een casus toegelicht van een residentiële zorgaanbieder die de woonzorgomgeving wil transformeren naar een inclusieve leefomgeving, waarbij ook wordt ingegaan op de manier waarop sociaal-ruimtelijk onderzoek in dit proces kan bijdragen aan een begrip van de-institutionalisering. Het vraagt van zowel sociaalwerkbeleid, - praktijk en -onderzoeksgebied om een ander handelen te verbeelden. En het is in die geest dat deze bijdrage afsluit met een verkenning van mogelijkheden van het retrospectieve denken over de toekomst.

Authors: Nguyen Nhu Lam , Tran Dinh Hung , Ngo Tuan Hung
Published: March 2024

This study investigated characteristics and factors affecting the outcome of massive burns in children. A retrospective study was conducted on 288 pediatric burn patients (=<16 years old) with burn extent ≥ 30% of total burn surface area (TBSA) admitted to the Le Huu Trac National Burns Hospital from 1/1/2018 to 31/12/ 2022. Patients were divided into two groups of survival and death comparing demographic characteristics, burn features, and outcome. The results showed that most patients were under 6 years old (79.51%), boys (64.58%), due to scald (76.69%). Inhalation injury accounted for 6.25% and the overall mortality rate was 6.94%. There was no remarkable difference between survival and death groups in terms of age, gender, and admission time (p > 0.05). Meanwhile, the death group had significantly greater burn extent, deep burn area as well as the rate of inhalation injury than the survival group (p < 0.01). The most fatal causal agent was flame as compared to scald and other agents (18.75%; p < 0.01). Multivariate analysis showed that the increased deep burn area and the presence of inhalation injury were independent risk factors for mortality with AUC = 0.82; sensitivity: 80%; specificity: 91.42% in the case of combining both variates.

Comparative Analysis of Wavelet Families in Image Compression, Featuring the Proposed New Wavelet
Authors: Öz İbrahim
Published: March 2024

Image compression is fundamental to the efficient and cost-effective use of digital media, including but not limited to medical imagery, satellite images, and daily photography. Wavelet transform is one of the best methods used in compression. This study conducts a meticulous comparative analysis of various established wavelet families and introduces a novel wavelet named new wavelet for image compression (NWI), shedding light on its performance compared to well-established counterparts. This research conducts a meticulous comparative analysis of various wavelet families to assess their performance in image compression. The results show that an average compression ratio of around 75% can be achieved with a 38 dB PSNR value for all test images. The best result was achieved with the test-2 image, with a compression performance (CP) of 3312.08, using the proposed NWI wavelet. The research evaluates eight wavelet families and shows that the performance of image compression depends on both image type and selected wavelet family while keeping the coding algorithm the same for all calculations of image processing scenarios. In image compression, introducing new wavelet families, such as the NWI, can enhance performance and achieve better results.

Published: March 2024

The present study employed an ex-post facto research design to investigate the impact of employee health and safety costs on the profitability of oil and gas companies listed on the Nigerian Exchange Group (NXG) in 2023. Utilizing data analysis techniques such as descriptive statistics, Pairwise Granger Causality Tests, Panel unit root tests, and Ordinary Least Squares (OLS) regression analysis through E-view-9 software, the study fills gaps in previous research by focusing specifically on this underexplored aspect of corporate expenditure. Through purposive sampling, the study ensures a comprehensive analysis of companies with up-to-date financial reports, enhancing the reliability and validity of the findings. The study found that there is insufficient evidence to conclude that employee health and safety costs have a significant direct effect on profitability for the listed oil and gas companies in Nigeria within the examined timeframe. By adopting a rigorous research methodology and statistical approach, the study provides valuable insights into the relationship between employee health and safety costs and profitability in the Nigerian oil and gas sector, contributing significantly to the existing literature and advancing understanding in this field. The study further suggested that oil and gas companies should implement proactive safety measures, such as regular training and equipment upgrades, to prevent workplace accidents and reduce associated costs. Also, they should enhance transparency by integrating employee health and safety metrics into sustainability reporting frameworks to build stakeholder trust and accountability.

Authors: Mardikaningsih Agusti , Kurniasari Praharisti , Pradipta Anangga
Published: March 2024

Critical thinking ability is one of the rational thinking capabilities that is highly required by students in solving problems or delivering an idea. In fact, however, students’ critical thinking skill is still categorized as low according to the previous studies. One feasible alternative to be done in developing students’ critical thinking ability is implementing electronic-based scaffolding. For that reason, there should be research to examine conceptual e-scaffolding in blended learning on Problem-Based Learning (PBL) model to observe the first semester students’ critical thinking ability at IKIP Budi Utomo Malang. This study employed mixed-methods with explanatory research design. The experimental group was given conceptual e-scaffolding treatment in blended learning on Problem-Based Learning model and the control group did not receive any additional treatment. For both experimental and control groups, the research subject was the students in the first semester at IKIP Budi Utomo Malang. As there were two research groups, 46 students belonged to the control group. The instruments utilized in this research were pre-test and post-test. The pre-test consisted of 18 multiple choice items with reliability coefficient of 0.735 and critical thinking post-test consisted of 14 essay question items with reliability coefficient of 0.762. In addition, semi-structured interview and think aloud guidelines were used. Quantitative data were obtained from the distribution of pre-test and post-test items. Meanwhile, qualitative data were retrieved from semi-structured interview and think aloud. The quantitative data were then analyzed using ANACOVA parametric analysis while the qualitative data were analyzed using path analysis model. The research findings indicated that: 1) the critical thinking ability of students who studied with conceptual e-scaffolding in blended learning on Problem-Based Learning was higher than those who studied with conventional method, 2) the implementation of conceptual e-scaffolding in the form of link map in Problem-Based Learning model influenced positively towards students’ critical thinking ability. This was reflected from the behavior and the way of thinking of students belonged to the experimental group indicating critical thinking ability development during the learning process. Furthermore, conceptual e-scaffolding in the form of link map helped the students to obtain information easily and utilized it in understanding concepts in geometrical optic material.
Profissionais cubanos e o “imigrante ideal”
Authors: Martínez Maria Beatriz Souza , Oliveira Marcia Maria de
Published: March 2024

A migração é fenômeno crescente e de origem variada, no caso de Cuba está fortemente presente em sua história e entre as principais características da sua sociedade. Após o final da Guerra Fria e o colapso da União Soviética, Cuba deixou de receber ajuda financeira da Rússia, até então seu principal parceiro econômico e político. Esta situação impulsionou uma crise econômica e abastecimento nos anos de 1990 na ilha, sendo chamado de ‘Período Especial’. Durante este período várias pessoas buscaram sair da ilha, tornando-se conhecida a figura do ‘balseiro’, pessoa que buscava sair do local por meio de embarcações precárias. Esses aspectos juntamente com as consequências advindas fizeram surgir um tipo de migrante com características específicas que são tratadas nessa pesquisa. O objetivo deste trabalho então é analisar a migração de profissionais cubanos conforme o conceito de ‘imigrante ideal’, de Fábio Koifman, e demais conceitos relativos à migração internacional, como ‘migrante qualificado’.

O freio lingual é uma estrutura anatômica que desenvolve importante papel no ato da sucção, fala e alimentação. A anquiloglossia constitui uma anomalia congênita sendo caracterizada por alteração no freio da língua que resulta em limitações dos movimentos dessa estrutura, podendo ser identificada em diferentes faixas etárias. O presente trabalho tem como proposição relatar um caso clínico de frenotomia lingual em paciente pediátrico, bem como, a conduta clínica e cirúrgica para o presente caso. Paciente, MCCC, do gênero feminino, 20 dias de idade, compareceu a um consultório odontológico em Jataí, para avaliação do freio lingual, o qual segundo a mãe a incomodava para mamar. A paciente foi submetida ao exame clínico, sendo verificada a presença de baixa inserção do freio lingual. Diante das características clínicas, o diagnóstico foi de anquiloglossia, e o plano de tratamento instituído foi a frenotomia lingual. O procedimento cirúrgico contou com as seguintes etapas: anestesia tópica, secção do freio lingual com a utilização de tesoura de ponta romba. Após a realização do procedimento cirúrgico pode-se observar melhor mobilidade da língua do paciente. Conclui-se que a frenotomia mostrou-se eficiente para melhorar a postura e mobilidade da língua, funções orais e sucção de leite materno.

A presente investigação teve por objetivo realizar um levantamento da agrobiodiversidade, animal e vegetal, em dois quintais agroflorestais urbanos no município de Benjamin Constant - AM, Alto Solimões, Fronteira Brasil-Peru-Colômbia. Para tanto, optou-se pelo estudo de caso de caráter exploratório, participante, autonarrativo, descritivo e qualitativo. No primeiro quintal, da família Sá, foram identificadas 50 espécies vegetais, sendo as frutíferas e medicinas prevalecentes. Algumas destas espécies também são consideradas de uso múltiplo pela família, como a mangueira e o jenipapeiro. Também foi observado a presença de pequenos animais domésticos, destacando-se as aves e quelônios, ambos destinados para alimentação dos seus mantenedores. No segundo quintal, da família Santos, foram encontradas 25 espécies vegetais e 03 espécies de animais domésticos. As espécies vegetais que mais se destacaram foram o açaizeiro (Euterpe precatoria), e em segundo lugar o coqueiro (Cocos nucifera), considerando os dois quintais investigados. Fica evidenciado que a diversificação de plantas cultivadas e a presença de animais domésticos, principalmente, as aves, comum nos dois quintais, contribuem para segurança alimentar e nutricional dos seus mantenedores. Os dois quintais também desempenham funções e serviços ecossistêmicos relevantes, principalmente, na provisão de alimentos e recursos medicinais. Ressalta-se que as plantas medicinais são fundamentais no tratamento primário de saúde das famílias, sendo essas utilizadas a partir do conhecimento tradicional associado aos metabólitos secundários presentes em suas diferentes estruturas botânicas. Foi observado que os quintais agroflorestais também conservam a agrobiodiversidade in situ/on farm de diversas espécies vegetais, nativas e cultivadas. Por fim, considerando a multifuncionalidade e importância dos QAFs, especificamente em Benjamin Constant-AM, recomendam-se mais estudos em uma perspectiva sistêmica e holística desses agroecossistemas.

As infecções pelos vírus da hepatite B (HBV) e C (HCV) podem apresentar curso crônico, com evoluçãopara em fibrose, cirrose e câncer de fígado. Entre indivíduos portadores do vírus da imunodeficiência humana ( HIV/AIDS), a alta prevalência de co-infecção por esses vírus hepatotrópicos representa um importante problema de saúde pública.. O estudo retrospectivo, de corte transversal, objetivou investigar prevalência, características epidemiológicas e genótipos dos vírus das hepatites B e C entre portadores de HIV/AIDS na Amazônia, durante os anos 2015 e 2016. Foram incluídos 404 (n = 404) indivíduos portadores de HIV/AIDS, atendidos em uma unidade de referência situada na cidade de Belém, Pará. Alíquotas de sangue, soro e plasma foram coletados. A contagem de linfócitos TCD4+ foi realizada por citometria de fluxo. A determinação da carga viral do HIV foi realizada por PCR quantitativo. Foram realizados testes sorológicos e moleculares para marcadores de infecção por HBV eHCV. Indivíduos que tinham HBsAg+ também foram testados para anti-HDV total. A presença de pelo menos um marcador de infecção por HBV foi detectado em 24,2% (98/404) dos participantes, oito (1,9%) foram também positivo para HBsAg+. Oitenta e oito participantes (21,8%) tinham anti-HBs+ isolado, indicando um perfil vacinal. Nenhum dos indivíduos com marcadores sorológicos apresentou contato com o HBV apresentavam anticorpos anti-HDV. Os valores de carga viral e HBV genótipos em relação à contagem de LT-CD4+ e carga viral do HIV foram detectados em oito indivíduos (1,9%) que apresentaram HBsAg+. A prevalência de anticorpos anti-HCV entre os participantes do estudo foi de 0,74% (3/404), sendo o HCV-RNA detectado por RT-qPCR em todas as amostras sorologicamente positivas. Dois participantes (0,5%) apresentaram resultados sorológicos inconclusivos para anti-HCV, entretanto nestes dois indivíduos o HCV-RNA não foi detectado. Entre as três amostras positivas pro HCV-RNA, duas pertenciam ao genótipo 1A e uma ao genótipo 3. Conclui-se que há uma ocorrência de coinfecção, tanto HBV/HIV quanto HCV/HIV, com prevalência inferior à encontrada no cenário nacional na Amazônia.

O contexto pandêmico gerado pela COVID-19, alterou bruscamente a educação no Brasil e no mundo, além de mudar o cotidiano e estilo de vida dos docentes dos cursos de Odontologia. Houve a necessidade de uma adaptação no modo de ensino, ocasionados pelo isolamento e distanciamento social que entraram em vigor. Todavia, esses novos modos de ensino, em específico com a implantação do ensino remoto, podem gerar problemas de saúde mental, como: ansiedade e estresse nos docentes. Dessa maneira, o este estudo teve como objetivo compreender as percepções relacionados as doenças mentais consequentes do contexto pandêmico da COVID-19, em docentes do curso de odontologia de diversas instituições de ensino superior durante o ensino remoto. Trata-se de uma pesquisa qualitativa com docentes de Odontologia, em que foi aplicado uma entrevista semiestruturada de forma remota. A entrevista semiestruturada foi gravada e realizada nas plataformas virtuais Google Meet ou Zoom, em dias e horários definidos pelo participante. As perguntas da entrevista abordaram sobre saúde mental no ensino remoto, possíveis sentimentos de estresse e ansiedade dos docentes durante o período pandêmico. Sendo que, a análise desses dados foi fundamentada na análise de conteúdo temática. O referencial teórico adotado foi as representações sociais, baseados no conceito de ancoragem e/ou objetivação. Foram encontradas quatro categorias: Objetivação dos sentimentos dos docentes; “Os dias e as noites parece que começaram a se misturar. […].”: contradição na qualidade do sono; Do temor ao alívio: retorno das atividades presenciais; Representação social dos docentes sobre as atividades de ensino. Conclui-se que o ensino remoto foram fatores estimuladores que comprometeram a saúde mental dos docentes.
