Resumen: Esta investigación psicométrica analizó la estructura interna y la confiabilidad del Inventario de Estrategias Metacognitivas de O’Neil y Abedi (1996) en una muestra de estudiantes universitarios de Perú. Para ello, se tomó una muestra intencional de 404 estudiantes de una universidad privada de la ciudad de Arequipa, de los cuales el 54,5% eran varones con una edad promedio de 19 años. Se aplicó la versión de la prueba validada por Vallejos et al. (2012), la cual tiene una estructura de tres factores: autoconciencia, autorregulación y evaluación. Para calcular la validez del instrumento se utilizó el análisis factorial confirmatorio, y para calcular la fiabilidad se emplearon la prueba alfa de Cronbach y la prueba omega de McDonald. Los resultados confirmaron la estructura trifactorial, pero sólo la primera dimensión obtuvo índices de fiabilidad adecuados.

Abstract: In this psychometric research, the internal structure and reliability of the Metacognitive Strategies Inventory by O’Neil and Abedi (1996) were analyzed in a sample of university students from Peru. For this purpose, an intentional sample of 404 students from a private university in the city of Arequipa was taken, of which 54.5% were men with an average age of 19 years. The version of the test validated by Vallejos et al. was applied, (2012) which has a three-factor structure: Self-knowledge, Self-regulation and Evaluation. To calculate the validity of the instrument, confirmatory factor analysis was applied, and to calculate reliability, Cronbach’s Alpha test and McDonald’s Omega test were applied. The results corroborated the three-factor structure, but only the first dimension obtained adequate reliability indices.

Abstract: Large Language Models (LLMs) are revolutionizing efficiency and automation in programming code generation. This study aims to provide an overview of these models' state-of-the-art and specific programming applications. The methodology enabled the identification of 549 initial publications, screened through successive phases to select 27 key articles for qualitative analysis. The results show that LLMs significantly improve the quality of generated code, enhance programmer productivity, and support learning through tools such as ChatGPT, Codex, and GitHub Copilot. The analysis highlights that 66.7% of the reviewed articles were published in 2024, reflecting a growing interest in this field. The United States leads research with 11 publications, followed by the Netherlands and Switzerland. The selected studies were filtered to generate a critical synthesis evaluating the quality and applicability of LLMs in code writing and debugging. This review examines the main advantages of LLMs, such as increased productivity and optimized code generation. However, it also addresses challenges like accuracy issues and the risk of generating errors or insecure code. LLMs can significantly enhance generated code quality and facilitate new programmers' learning curve. Nevertheless, the need for rigorous human oversight is emphasized to ensure the reliability of the solutions generated by these models.

Abstract: The present research is carried out for the improvement of the availability of a hydroelectric power plant through a wear-sediment quantity correlation model for the scheduling of its preventive maintenance, the data is based on the measurement of blade thicknesses, as well as visual inspection to identify discontinuities in the water equipment, once the data has been collected, data analysis techniques can be used to evaluate the condition of the Francis turbine and determine the need for preventive maintenance under working condition. The data analysis detailed is the least squares method where the independent variables considered are power and suspended particles with their nephelometric unit of measurement of turbidity in parts per million (PPM). By means of the aforementioned analysis, it is possible to complete the results with the projection of the wear to years after the data obtained from the inspection point, and it also allows taking preventive measures before a failure occurs, which helps to reduce downtime and maintenance costs. Thus, the hydroelectric power plant under study has an annual average availability of 97.21 %, reduced by the suspension of power generation due to reservoir flushing and scheduled maintenance shutdowns. While the annual average reliability is 99.89 %, it is reduced by unscheduled failures. The result of the correlation statistical model determined the preventive maintenance for improvement conditions of 98 % of the availability in the hydroelectric power plant and is reflected in the reduction of days of no electricity generation.

Resumen: La presente investigación se realiza para la mejora de la disponibilidad de una Central Hidroeléctrica a través de un modelo de correlación desgaste-cantidad de sedimentos para la programación de su mantenimiento preventivo, los datos se basan en la medición de espesores de los alabes, así como la inspección visual para identificar discontinuadas en los equipos hídricos, una vez que se han recopilado los datos, se pueden utilizar técnicas de análisis de datos para evaluar el estado de la turbina Francis y determinar la necesidad de mantenimiento preventivo bajo condición de trabajo. El análisis de datos que se detalla es el método de mínimos cuadrados donde las variables independientes que se consideran son potencia y partículas de suspensión con su unidad de medida nefelométricas de turbidez en partes por millón (PPM). Mediante el análisis mencionado se logra culminar los resultados con la proyección del desgaste a años posteriores a los datos obtenidos del punto de inspección, además que permite tomar medidas preventivas antes de que se produzca una falla, lo que ayuda a reducir el tiempo de inactividad y los costos de mantenimiento. Es así como la Central Hidroeléctrica en estudio tiene un promedio anual del 97.21 % de disponibilidad, se reduce por la suspensión de la generación eléctrica, debido al lavado del embalse y las paradas por mantenimiento programado. Mientras que, la confiabilidad promedio anual es el 99.89 %, se reduce por fallas no programadas. El resultado del modelo estadístico de correlación determino el mantenimiento preventivo por condiciones de mejora del 98 % de la disponibilidad en la Central Hidroeléctrica y se refleja en la disminución de días de no generación eléctrica.

Resumen: En Es | Texto: En Es | PDF: En | PDF: Es

ABSTRACT: Buccal mucosal grafts are versatile in medical practice, documented minimally despite potential in otolaryngology, ophthalmology, dermatology, plastic surgery and urology. They offer advantages such as being hairless, easily obtained, and infection-resistant, with a thin, highly vascularized epithelial layer aiding absorption and reducing contracture risk. Complications from oral donor sites, like pain and sensory changes, are known, relevant in conditions such as Fournier's gangrene, necessitating urgent surgical intervention and often reconstruction. We present a case report of a 45-year-old male with Fournier's gangrene treated jointly by urology and maxillofacial surgery. Buccal mucosal grafts were harvested from the inner cheek mucosa for simultaneous urethral reconstruction. The procedure preserved the parotid duct, obtaining a graft comprising mucosal, submucosal, and glandular tissues, applied to the urethral defect with bovine dermis coverage. Postoperative recovery was uneventful, with successful catheter removal in 2 weeks and complete donor site healing in 6 months. Buccal mucosal grafts prove effective in complex reconstruction, offering structural integrity and minimal morbidity. Despite challenges like graft contraction and limited tissue availability in severe cases, buccal mucosal grafts are favored for reliability and patient satisfaction in reconstructive needs, notably urethral reconstruction. The evidence shows a high success rate in most of the uses of buccal mucosal grafts, so it is recommended as an effective and safe graft for extraoral reconstructions, particularly urethral reconstruction, where the Maxillofacial Surgeon is part of the interdisciplinary team. Awareness of potential complications and procedural limitations ensures optimal outcomes and patient care.

RESUMEN: Los injertos de mucosa bucal son versátiles en la práctica médica, documentados mínimamente a pesar de su potencial en otorrinolaringología, oftalmología, dermatología, cirugía plástica y urología. Ofrecen ventajas como la ausencia de vello, facilidad de obtención y resistencia a infecciones, con una capa epitelial delgada y altamente vascularizada que favorece la absorción y reduce el riesgo de contractura. Se conocen complicaciones de los sitios donantes orales, como dolor y cambios sensoriales, que son relevantes en condiciones como la gangrena de Fournier, que requieren intervención quirúrgica urgente y a menudo reconstrucción. Presentamos el reporte de caso de un hombre de 45 años con gangrena de Fournier tratado de manera conjunta por Urología y Cirugía maxilofacial. Se obtuvo injertos de mucosa bucal de la mucosa interna de la mejilla para la reconstrucción uretral simultánea. El procedimiento preservó el conducto parotídeo, obteniendo un injerto que comprendía tejidos mucosos, submucosos y glandulares, aplicado al defecto uretral con cobertura de dermis bovina. La recuperación postoperatoria curso sin complicaciones, con la retirada exitosa del catéter a las 2 semanas y la completa cicatrización del sitio donante en 6 meses. Los injertos de mucosa bucal demuestran ser efectivos en reconstrucciones complejas, ofreciendo integridad estructural y mínima morbilidad. A pesar de los desafíos, como la contracción del injerto y la disponibilidad limitada de tejido en casos severos, los injertos de mucosa bucal son preferidos por su fiabilidad y satisfacción del paciente en necesidades reconstructivas, especialmente en la reconstrucción uretral. La evidencia muestra una alta tasa de éxito en la mayoría de los usos de injertos de mucosa bucal, por lo que se recomienda como un injerto eficaz y seguro para reconstrucciones extraorales, particularmente en la reconstrucción uretral, donde el cirujano maxilofacial forma parte del equipo interdisciplinario. La conciencia sobre las posibles complicaciones y limitaciones del procedimiento asegura resultados óptimos y un adecuado cuidado del paciente.

Resumen: En | Texto: En | PDF: En

The perceived lack of reliability is one aspect of peer assessment that makes educators reluctant to use it in their teaching. This study was done among third-year information systems students who had to assess two assignments of their peers by using rubrics. The rubrics differed in the sense that the one was more detailed requiring less subjective judgement while the other one was less detailed and required more subjective judgement from assessors. To determine the reliability of the peer assessment process, all the assignments of the participants in the study were reassessed by the lecturer and the marks compared. While the reliability of the peer assessment of both projects was acceptable, the assessment of the assignment requiring less judgement was more reliable compared to the assignment requiring more subjective judgement. A survey done among the participants revealed that they were happy with their marks and with the effort put in by their peers in assessing them. A significant number of students believed their peers awarded them higher marks for both assignments; however, this was only found to be the case for the assignment requiring more subjective judgment. It was also found that while the ratings of one peer rater resulted in reliable marks when the detailed rubric was used, it was not the case for the rubric requiring more subjective judgement. This study provides motivation for educators to use peer assessment as fears about the reliability thereof is unwarranted provided that properly designed rubrics are used, and students are adequately guided through the process.

Resumen: En | Texto: En | PDF: En

BACKGROUND: Many serious adverse events associated with gestational diabetes mellitus (GDM) can be mitigated by timely glucose control during pregnancy, achieved through education and lifestyle choices. The aim of this study was to translate and cross-culturally adapt and test the preliminary internal consistency and test-retest reliability of the South African English, Afrikaans and isiXhosa versions of the GDM Knowledge Questionnaire (GDMKQ). METHODS: A prospective, observational study was conducted at a high-risk antenatal clinic in South Africa. Pregnant women ≥ 18 years with GDM were consecutively sampled. Semantic equivalence between the original and adapted versions was assessed. Face and content validity, internal consistency and test-retest reliability were evaluated. RESULTS: The three SA-GDMKQ versions demonstrated good face and content validity. For internal consistency, Cronbach's alpha values were 0.534 for the Afrikaans version, 0.434 for the English version and 0.621 for the isiXhosa version. Test-retest reliability found kappa (standard error [s.e.]) values ranged between −0.03 (0.18) and 0.89 (0.13) for the English version, between −0.07 (0.18) and 0.53 (0.13) for the Afrikaans version and between 0.28 (0.18) and 0.87 (0.17) for the isiXhosa version. All versions of the SA-GDMKQ had a statistically significant (p < 0.001) positive linear correlation between the total scores. CONCLUSION: The English, Afrikaans and isiXhosa SA-GDMKQ versions were found to be feasible and easy to comprehend, although lower internal consistency and test-retest reliability were displayed. Further validation of the psychometric properties of the English, Afrikaans and isiXhosa versions of the SA-GDMKQ among larger sample groups is however warranted. CONTRIBUTION: This study adds to the knowledge around developing and using culturally appropriate questionnaires and outcome measures in research and clinical practice.

Resumen: En | Texto: En | PDF: En

A nutating grinding mill, exemplified by the commercial HICOM mill, achieves efficient particle size reduction through the accelerated motion of the material charge within the nutating chamber. This design, characterised by high particle velocities and rapid charge circulation, offers a compact solution compared to tumbling mills. There have been concerns regarding the mechanical reliability of kinetic joints for certain specialised mining applications. Recognising the need to model internal forces in such systems, this study focuses on the uncoupled simulation using multibody dynamics and the discrete element method. The investigation employed a small-scale experimental test mill, referred to as the NuMILL, featuring a cylindrical chamber (140 mm internal diameter, 245 mm height, 6° nutation angle). Instrumented with an array of sensors, the NuMILL provided internal load data for validating the simulations. Experiments were conducted with an empty chamber or filled with charge material. Charge materials included coarse sand or steel pellets with a charge-to-chamber mass ratio of 0.25. The mill speed ranged between 100 to 700 RPM. Multibody dynamics modelled resultant inertial and frictional loads within 5%, while the discrete element method simulated the internal material contact loads with accuracies ranging from 1% to 19%. The combined simulation approach predicted the resultant forces in the critical kinetic joint within a 20% margin. Representing the charge using rigid lumped mass elements was also studied. The presented simulation techniques, validated against experimental data, offer a robust foundation for analysing larger systems, including the industrial-scale HICOM.

Abstract The aim was to map evidence on the quality of records in the Mortality Information System (SIM) through a national scoping review of articles published up to April 2023 across five databases (PubMed, Embase, Scopus, LILACS, and SciELO). Studies focused on specific causes of death were excluded. Dimensions evaluated included accessibility, methodological clarity, coverage, completeness, reliability, consistency, non-duplication, timeliness, validity, and studies on ill-defined causes/garbage codes. Among the 33 included articles, a general improvement in SIM quality was observed, with a 68.5% reduction in garbage codes (2000-2015). However, regional inequalities in SIM persist, with coverage below 90% in Acre and Maranhão and poorer performance in the North and Northeast regions. A robust SIM is essential for public health strategies aimed at preventing avoidable deaths.

Resumo O objetivo foi mapear evidências sobre a qualidade dos registros do Sistema de Informação sobre Mortalidade (SIM) por meio de revisão de escopo nacional com artigos publicados até abril de 2023 em cinco bases (PubMed, Embase, scopus, LILACS e SciELO). Excluíram-se estudos focados em causas específicas de óbito. Foram avaliadas dimensões como acessibilidade, clareza metodologica, cobertura, completitude, confiabilidade, consistencia, nao-duplicidade, oportunidade, validade e estudos de causas mal definidas/garbage codes.. Dos 33 artigos incluídos, observou-se melhoria geral da qualidade do SIM, com redução de 68,5% nos garbage codes (2000-2015). Contudo, persistem desigualdades regionais no SIM, com cobertura abaixo de 90% no Acre e Maranhão e pior desempenho nas regiões Norte e Nordeste. Um SIM robusto é essencial para estratégias de saúde pública voltadas à prevenção de mortes evitáveis.

Resumo O Oxford Happiness Questionnaire-Short Form (OHQ-SF) é uma escala de 8 itens que avalia a felicidade e foi adaptada para uso com indivíduos espanhóis. No entanto, nenhum estudo examinou a sua validade estrutural e invariância de gênero em adultos jovens. Para verificar isso, as propriedades psicométricas do OHQ-SF foram analisadas em uma amostra de 625 universitários espanhóis (175 homens, 28%, e 450 mulheres, 72%), com faixa etária entre 18 e 29 anos (M = 20,80, DP = 2,40). Foram utilizadas adaptações espanholas do OHQ-SF, Purpose In Life Test-10 Items (PIL-10), Satisfaction With Life Scales (SWLS) e Seeking of Noetic Goals (SONG). O OHQ-SF apresentou consistência interna de 0,66, confiabilidade composta de 0,68, correlação média entre itens de 0,21 e correlações totais de itens variando de 0,27 a 0,52 (M = 0,36). Os procedimentos confirmatórios revelaram um ajuste excelente para o OHQ-SF (SBχ2(20) = 22,387, p = 0,320, CFI = 0,996, TLI = 0,995, RMSEA = 0,014) e invariância configural, métrica, escalar e estrita entre grupos de gênero. A diferença entre a média das mulheres (36,40, DP = 5,3) e a média dos homens (36,27, DP = 5,09) no OHQ-SF não foi significativa (t(623) = -0,285, p = 0,776). As correlações entre o OHQ-SF, o PIL-10, o SWLS e o SONG-8 foram fortes e significativas (ρ = 0,61, p < 0,001; ρ = 0,64, p < 0,001; e ρ = -. 38, p < 0,001 respectivamente). Estes resultados confirmam que a versão espanhola do OHQ-SF, utilizada com estudantes espanhóis no presente estudo, é uma escala confiável e válida.

Abstract The Oxford Happiness Questionnaire-Short Form (OHQ-SF) is an 8-item scale that assesses happiness, and it has been adapted for use with Spanish individuals. However, no study has examined its structural validity and gender invariance in young adults. To check this, the psychometric properties of the OHQ-SF were analyzed in a sample of 625 Spanish undergraduates (175 men, 28%, and 450 women, 72%), with an age range between 18 and 29 years (M = 20.80, SD = 2.40). Spanish adaptations of the OHQ-SF, Purpose In Life Test-10 Items (PIL-10), Satisfaction With Life Scales (SWLS), and Seeking of Noetic Goals (SONG) were used. The OHQ-SF showed an internal consistency of .66, a composite reliability of .68, an average inter-item correlation of .21, and total-item correlations ranging from .27 to .52 (M = .36). Confirmatory procedures revealed an excellent fit for the OHQ-SF (SBχ2(20) = 22.387, p = .320, CFI = .996, TLI = .995, RMSEA = .014), and configural, metric, scalar, and strict invariance across gender groups. The difference between the women’s mean (36.40, SD = 5.3) and the men’s mean (36.27, SD = 5.09) in the OHQ-SF was not significant (t(623) = -.285, p = .776). Correlations between the OHQ-SF, the PIL-10, the SWLS, and the SONG-8 were strong and significant (ρ = .61, p < .001; ρ = .64, p < .001; and ρ = -.38, p < .001 respectively). These results confirm that the Spanish version of the OHQ-SF, used with Spanish undergraduates in the present study, is a reliable and valid scale.

Resumen: En | Texto: En | PDF: En

Abstract This article presents a comparative study of the reliability of reinforced concrete (RC) cross-sections subjected to simple bending, designed at the ultimate limit state and following the recommendations of the 2014 and 2023 versions of the Brazilian code NBR 6118. The analyses are based on reliability theory by implementing the FORM algorithm on three rectangular cross-section configurations, considering three constant values of dimensionless bending moments and five different concrete strength classes between C30 and C90. Although the elements designed by NBR 6118:2023 have shown additions of up to 19% in the total steel cross-section area as a consequence of the implementation of the strength reduction factor ( η c), the results show no significant improvements in reliability compared to the 2014 previous version of NBR 6118.

Resumen: En | Texto: En | PDF: En

Abstract Although it is recognized that periodontal disease negatively impacts quality of life, there is no validated instrument to assess this impact in Brazil. This study aimed to translate, cross-culturally adapt, and validate the OHIP 14 PD (Oral Health Impact Profile Applied to Periodontal Diseases) for application among Brazilian patients. The original instrument was translated and validated into Brazilian Portuguese in a cross-sectional study with 110 participants recruited from a Dental School clinic. The sample was divided into two groups: 55 with periodontal disease and 55 without periodontal disease. The instrument was self-administered twice within an interval of 7 to 10 days for patients with periodontal disease. The psychometric properties of the Brazilian version were verified using internal consistency (Cronbach’s α) and the reliability through the test-retest method (ICC, intraclass correlation coefficient), convergent validity (Spearman correlation), and discriminant validity (Mann-Whitney test), with p <0.05. Most of the sample consisted of women (n=69; ±40.65 years). The OHIP 14 DP - Br showed excellent internal consistency (α=0.997) and outstanding reliability using the test-retest method (ICC=0.945, p<0.001). There was a significant correlation between the scores obtained in all seven domains between this questionnaire and self-perceived gingival health (p=0.023). This study provides psychometric evidence supporting the cross-cultural validity of the OHIP 14 DP - Br version for use in Brazil.

Resumen: En | Texto: En | PDF: En

Abstract This article presents an application for failure probability in long-pipeline gas systems through the development of trend curves over time for the attributes of corrosion wear, which are related to the length, width, and depth of the defect. In addition, Risk-Based Inspection (RBI) is applied in the most favorable numerical failure values according to the location of the defect, with the aim of analyzing the structural reliability and the expected useful life of the gas pipeline. To do this, it was necessary to use the data provided by pig readings in 2008, 2012 and 2018 by an instrumented pig, type Magnetic Flux Leakage (MFL), inspecting a gas pipeline with the finality to measure wall thickness. The 56 km long and 18 in diameter pipeline is partly onshore and partly offshore. Also, the pipeline anomalies are standardized according to the standards established in POF (2016). It is important to emphasize that the methodology described in this article can be used in the industry where the prevention of leakage incidents, the predictability of maintenance, and the elaboration of the respective inspection plans are required, since it has been theoretically possible to calculate the probability of failure in time beyond the respective impact on risk for the operational variables presented.

Resumo O efeito do confinamento lateral em lajes de concreto armado é amplamente reconhecido por sua capacidade de aumentar a carga última suportada. Nesse contexto, este estudo propõe uma análise da confiabilidade de lajes dimensionadas conforme as normas brasileiras, considerando ou não o fenômeno, com o objetivo de estabelecer uma comparação entre os casos. Utilizou-se um modelo numérico desenvolvido no software ANSYS, calibrado a partir de resultados experimentais, para determinar as cargas de ruptura das lajes. O Método de Simulação de Monte Carlo foi empregado na obtenção das probabilidades de falha e índices de confiabilidade. Adicionalmente, conduziu-se um estudo paramétrico para compreender os principais fatores que influenciam os índices de confiabilidade, considerando ou não o confinamento lateral. Os resultados indicaram um aumento significativo na confiabilidade das lajes quando o confinamento lateral foi considerado, elevando o índice de confiabilidade médio de 3,29 para 4,44. O estudo paramétrico revelou que os fatores influenciando a confiabilidade das lajes confinadas são similares àqueles obtidos desprezando-se o efeito, também demonstrado pela forte correlação entre os índices de confiabilidade de lajes confinadas e não confinadas.

Abstract The effect of lateral confinement in reinforced concrete slabs is widely recognized for its ability to increase the supported ultimate load. In this context, this study proposes a reliability analysis of slabs designed according to Brazilian standards, considering or not the phenomenon, with the goal of establishing a comparison between the cases. A numerical model developed in ANSYS software, calibrated from experimental results, was used to determine the slabs' failure loads. The Monte Carlo Simulation Method was employed to obtain the failure probabilities and reliability indexes. Additionally, a parametric study was conducted to understand the main factors influencing the reliability, whether considering lateral confinement or not. The results indicated a significant increase in the reliability of the slabs when lateral confinement was considered, raising the average reliability index from 3.29 to 4.44. The parametric study revealed that the factors influencing the reliability of confined slabs are similar to those obtained when not considering it, as also demonstrated by the strong correlation between the reliability indexes of confined and unconfined slabs.

Resumen: En | Texto: En | PDF: En

Abstract The Corneometer CM® 825 from Courage & Khazaka electronic GmbH is widely utilized in clinical efficacy testing of cosmetics. Assessing methodological variables is crucial for ensuring the reliability of the process. The aim of this study was to evaluate the operational and instrumental parameters of the Corneometer CM® 825 in the clinical assessment of skin hydration levels. Precision and accuracy of the measurements were assessed by measuring hydration levels on 10 participants in specific areas of the forearm and face. Three different skin conditions (dry, normal, and hydrated) resulting from the use or non-use of moisturizing cosmetics and a drying promoter were evaluated within 120 minutes of their application. The electrical capacitance method demonstrated good repeatability, with coefficients of variation mostly below 10%. However, higher variability was observed in inter-observer readings. The equipment exhibited high sensitivity and accurately discriminated the differences between hydrated and dry skin. Operational training and standardization of the methodology are essential to ensure accurate, reproducible, and reliable results in studies utilizing the Corneometer equipment for assessing skin hydration levels.
