Item type:Publicación, Technological skills, self-efficacy, and resilience with SEM model as predictors of investigative skills in Ecuatorian higher-level students(2026-04-28) ;Chávez-Arizala, Jenrry FredyResearch skills are essential for academic and professional training in higher education; however, their development faces significant challenges, especially in contexts such as Ecuador, where few studies analyze the factors that shape them. The objective of the study was to determine the extent to which technological competencies, academic self-efficacy, and resilience predict research competencies among Ecuadorian higher education students. The methodology applied was an empirical, cross-sectional, correlational, explanatory research with a non-experimental design. The analysis was implemented using the structural equation model (SEM). 517 students from two higher education institutions in Ecuador participated. Four validated instruments were administered: the Digital Competence Questionnaire for Future Teachers (CCDFM), the Perceived Self-Efficacy Scale Specific to Academic Situations (EAPESA), the Brief Resilience Scale (CD-RISC-10), and the Perceived Research Competencies Scale (RPCs). Data were analyzed using SEM, with adjustments evaluated using CFI, RMSEA, and SRMR. Results: The SEM model showed an adequate fit (CFI = 0.901; RMSEA = 0.079 and SRMR = 0.376). Technological competencies (β = 0.51, p < 0.001) and resilience (β = 0.16, p < 0.001) were significant predictors of research competencies, while academic self-efficacy did not show a significant direct relationship (p = 0.157). The correlations showed positive associations among all variables (r = 0.48–0.66, p < 0.001). It is concluded that integrating technological competencies and resilience strategies into university programs strengthens research skills.Citas (OpenAlex): 1metric-badges.view 1 - Algunas métricas están bloqueadas por suconfiguración de consentimiento

Item type:Publicación, Sistema experto “KALM” para el mantenimiento preventivo correctivo en la red telefónica peruana(2016-02-23) ;Leiva Povis, Jorge ZenónEn la red telefonica se tiene soporte de comunicaciones de los variados servicios para la atencion de diversos clientes naturales e institucionales, con la frecuente evolucion de los sistemas de mantenimiento, y la rotacion de los operadores dentro del esquema de organizacion responsable del mantenimiento de la red, constituyendo elementos adicionales que subrayan la necesidad de aplicar tecnicas tecnologicas que permitan la prevencion del corte de los servicios. Para erradicar las distorsiones y cortes de la transmision de la informacion a traves de los diferentes nodos que circulan la informacion hasta que llegue al cliente final, se ha desarrollado un sistema experto basado en reglas difusas para identificar los posibles cortes de trasferencia y bits errados de informacion en un nodo determinado. Al identificar los errores de informacion, se vuelve a retransmitir la informacion errada logrando garantizar una calidad de informacion adecuada para el cliente final que lo espera cuando realiza una peticion.Citas (OpenAlex): 0metric-badges.view 8 - Algunas métricas están bloqueadas por suconfiguración de consentimiento
Item type:Publicación, Evidencias psicométricas y análisis de red de la escala inteligencia emocional en estudiantes de instituciones confesionales(2023-09-29); ;Murillo-Antón, JaiminINTRODUCCIÓN. La inteligencia emocional es un constructo que se estudia a partir de tres enfoques, basados en habilidades, en rasgos y mixto, esto ha permitido el desarrollo de diversos instrumentos que han hecho hincapié en la adaptación en diferentes contextos. El presente estudio tiene como objetivo evidenciar las propiedades psicométricas y analizar la red de la escala inteligencia emocional en estudiantes adolescentes de instituciones confesionales. MÉTODO. El método es instrumental con una muestra transversal de 550 estudiantes encuestados. Los datos recolectados tuvieron un análisis de fiabilidad igual a ω = 0.933, que permitió aplicar un estudio de la estructura interna basado en el análisis factorial exploratorio (AFE; n = 280) y en el análisis factorial confirmatorio (AFC; n = 270); después de conocer la estructura factorial de la escala se aplicó un análisis de red con la finalidad de mostrar los nodos y las aristas que reflejan las conexiones entre las variables y el índice de centralidad por variable. RESULTADOS. Los resultados muestran que la estructura original se redujo significativamente a una estructura factorial más robusta, basada en 22 items con cargas factoriales mayores a 0.5, cuya estructura se corrobora con el análisis AFC a partir de cuatro factores de la escala inteligencia emocional con índice de bondad de ajuste significativos (X2 < 3; p-valor < 0.001; TLI = 0.939; CFI = 0.947; RMSEA = 0.055); además, el análisis de red de la escala inteligencia emocional encontró nodos y aristas representativas. DISCUSIÓN. Finalmente, el valor de la escala, con una estructura basada en 22 items, mide adecuadamente la inteligencia emocional y puede ser utilizada en estudiantes.Citas (OpenAlex): 1metric-badges.view 7 - Algunas métricas están bloqueadas por suconfiguración de consentimiento
Item type:Publicación, Characterization of diet in biochemical and anthropometric profiles with principal component analysis in obese patients, Guayaquil - Ecuador(2023-09-19) ;Gomez Rutti, Yuliana Y. ;Gordillo Cortaza, Janet Del R.Objectives: To determine the characterization of the diet in biochemical and anthropometric profiles with principal component analysis in obese Ecuadorian patients. Methods: Descriptive, comparative, longitudinal studies; we had access to the institutional health clinical history database and a study group was formed, they were offered a low-carbohydrate diet. The sample consisted of 110 obese patients from the Hospital of Guayaquil-Ecuador. Results: The patients were between the ages of 25 to 65 years. The results showed a significant loss of BMI (kg/m2) (Δ-2.6±1.9) (p<0.001), waist circumference (cm) (Δ-5.1±4.7) (p<0.001), body fat (%) (Δ-3.6±3.6) (p<0.001), triglycerides (mg/dL) (Δ-25.4±72.9) (p<0.001) and glucose (mg/dL) (Δ-6.8±9.6) (p<0.001). Conclusion: The low carbohydrate diet reduces BMI, waist circumference, body fat, triglycerides and glucose in obese patients.Citas (OpenAlex): 1metric-badges.view 4 - Algunas métricas están bloqueadas por suconfiguración de consentimiento

Item type:Publicación, Transformations for non-destructive evaluation of brix in mango by reflectance spectroscopy and machine learning(2023-11-14) ;Ernesto Paiva-Peredo ;Diego Gonzales-Rodriguez ;W. T. Herrera; Mango is a very popular climacteric fruit in America and Europe. Among the internal properties of the mango, total soluble solids (TSS) are an adequate indicator to estimate the quality of mango, however, the measurement of this indicator requires destructive tests. Several research have addressed similar issues; they have made use of pre-processing transformations without making it clear which of them is statistically better. Here, we created a new spectral database to build machine learning (ML) models. We analyzed a total of 18 principal component regression (PCR) models and 18 partial least squared regression (PLSR) models, where 4 types of transformations, 3 different feature extractors, and 3 different pre-processing techniques are combined. The research proposes a double cross validation (CV) both to determine the optimal number of components and to obtain the final metrics. The best model had a root mean square error (RMSE) of 1.1382 °Brix and a RMSE on the transformed scale of 0.5140. The best model used 4 components, used y2 transformation, reflectance R as the independent variable and MSC as a pre-processing technique.Citas (OpenAlex): 3metric-badges.view 4 - Algunas métricas están bloqueadas por suconfiguración de consentimiento
