A nivel mundial, los países han utilizado durante mucho tiempo un mecanismo conocido actualmente como estados de excepción, el cual otorga facultades extraordinarias a los gobiernos para gestionar emergencias en situaciones no regulares, como desastres naturales, conflictos armados o crisis internas. Este estudio analiza los principios de razonabilidad en los estados de excepción decretados en Ecuador entre 2015 y 2019, evaluando su aplicación y cumplimiento. Los resultados revelan un incumplimiento en los principios fundamentales que regulan los estados de excepción, con énfasis en el principio de temporalidad, lo que debilita su eficacia como instrumento de gobernabilidad. Durante el período analizado, en Ecuador se priorizó el principio de necesidad sobre otros principios clave, como proporcionalidad, legalidad, temporalidad, territorialidad y razonabilidad. Además, el principio de razonabilidad en la legislación ecuatoriana muestra un alto grado de subjetividad, dependiendo en gran medida del criterio del gobernante en turno, lo que impacta significativamente la aplicación del estado de excepción. Este estudio contribuye al análisis de la aplicación de los estados de excepción en Ecuador y destaca la necesidad de fortalecer su marco normativo para garantizar un equilibrio adecuado entre seguridad y derechos fundamentales.

El diseño y operación de los programas de mejora continua Lean, representan una estrategia de largo plazo para mejorar el desempeño operativo en compañías. Su diseño generalmente está inspirado en el modelo del Sistema de Producción Toyota y producción esbelta. El grado de madurez del programa de mejora continua Lean, está asociado a una mayor productividad de las plantas. El objetivo de este estudio fue conocer, cual es el grado de madurez de esos programas que se han implementado en empresas multinacionales de manufactura automotriz en México. Se recolectó información por linkedin de una encuesta diseñada en una plataforma especializada en internet. De una muestra de 157 plantas, 10.1 % mostraron un alto grado de madurez en su programa de mejora Lean, 61 % mostraron un grado de conformación integral de acuerdo al modelo de investigación. Para identificar técnicas Lean con mayor grado de implementación profunda, se utilizó un análisis de conglomerados de k-medias, los resultados indican que las técnicas Lean con mayor grado de implementación, son calidad en la fuente, 5´s y trabajo estándar. Las técnicas Lean con menor grado de implementación están asociadas conceptualmente al pilar del Justo a tiempo en el modelo del Sistema de Producción Toyota.

En el negocio de la moda existe una gran variedad de ropa, cada una con un nombre propio para identificar de qué tipo de prenda se trata. El presente artículo describe un método para generar un modelo que identifique el tipo de ropa en base a 15 categorías, aplicando la tecnología de identificación de imágenes y aprendizaje automático como son las redes neuronales convolucionales bajo la utilización de la librería de Google TensorFlow, para elaborar un clasificador de ropa de moda. Concluyendo después de la fase de pruebas se alcanzó un 95 % de exactitud. Mientras que con un conjunto de prueba externo se logró un 70%, considerando la calidad de las imágenes como uno de los posibles motivos de falla.

Objective: to present and describe the clinical manifestations of ligneous (woody) conjunctivitis in a patient seen at Hospital de San José in Bogotá. Design: descriptive, retrospective study and case report. Methodology: review and analysis of the literature with reference to the diagnosis of the pathology, with variables as similar as possible to those found in the patient, with the purpose of characterizing the condition and determining a satisfactory management. Description: a 19-year-old patient with early manifestations (from birth) consisting of giant papilla type lesions in upper tarsal conjunctiva in both eyes. Confluent papillae with lobed masses dependent on the superior tarsal conjunctiva were evidenced upon ophthalmological exam. The biopsy confirmed the diagnosis of congenital woody conjunctivitis.

The principle of fiscal objectivity in the pre-trial stage constitutes an optimization mandate that is of the utmost importance for the criminal process, as it guarantees compliance with the rights of the person under investigation and of the victims. The modern accusatory system requires the prosecutor to act impartially, objectively, adjusted to the reality of the elements obtained during the preliminary investigation, and imposes the obligation to incorporate into the process both the elements against the investigated party and those that are in his favor. In addition to the fact that ethical behavior and a sense of justice are required of the prosecutor. The objective of this paper is to analyze the role played by compliance with the principle of objectivity and its importance, in charge of the prosecutor in the pre-trial stage in Ecuador. Methods of the Social Sciences are used, such as the historical-logical, the analysis-synthesis, or particularly legal, such as the exegetical; in terms of techniques, documentary review. As results, a theoretical systematization is obtained about the principle of fiscal objectivity in the Ecuadorian pre-procedural stage, as well as practical manifestations in Ecuador.

A low-cost automated greenhouse prototype was developed, which can be installed on rooftops, gardens, and even commercial greenhouses.

Introduction:This study proposes an analysis of the organizational climate and job satisfaction in nursing workers, seeing that work also carries positive elements, which impact on well-being and reduction of weakness throughout the productive life.Method: This is a exploratory study, with a quantitative approach, developed in the university hospital, with 242 active nursing workers.To the data collection were carried three instruments: Sociodemographic and Professional Characterization Questionnaire, the Organizational Climate Scale for Health Organizations (OCSHO), and the Job Satisfaction Questionnaire -S20/S23, valued to the Brazilian context.The descriptive analysis occurred through averages, standard deviation.To the associations between job satisfaction and organizational climate were applied the correlation coefficient of Pearson, and the correlation coefficient of Spearman.To establish comparisons among the score of Job Satisfaction averages according to the categories of the quantitative variables initially was assessed the variance homogeneity through the Barlett test, bearing in mind that the variables presented constant variance, the ANOVA Test, and afterward the post hoc test of Bonferroni for multiple comparisons.Results: It was found that nursing workers feel satisfied, with an overall score of 3.22 points, with the highest index related to intrinsic job satisfaction, with 3.30 points.As for the assessment of the organizational climate, workers reported being favorable, with a score of 3.49, ranging from 1.63 to 5.00 points, with the highest index related to leadership, with 3.81 points.The analysis of the association between Job Satisfaction and Organizational Climate identified a statistically significant correlation between climate and satisfaction, proving that the higher organizational climate score, the greater the job satisfaction.Conclusions: a statistically meaningful correlation between climate and satisfaction was identified, with a highlight to the issues concerning the satisfaction intrinsic to work, leadership, and higher age.It stands out

Heterojunctions made of n-type cadmium sulfide (CdS) and p-type zinc telluride (ZnTe) thin films with rectifying behavior have been developed using an in situ approach based on pulsed laser deposition (PLD). The structure of the CdS and ZnTe thin films was observed by x-ray diffraction (XRD) analysis. Optical and electrical characterization of the semiconductor films and fabricated diodes is also reported herein. For this purpose, a set of CdS/ZnTe diodes was fabricated with circular gold contacts of varying diameters from 100 µm to 300 µm. The carrier concentrations of the semiconductor layers were determined using a Hall-effect measurement system, yielding values of 5.26 × 1018 cm−3 and 3.5 × 1013 cm−3 for CdS and ZnTe, respectively. Current–voltage (I–V) characteristic curves were used to observe the typical rectifier behavior over three orders of magnification. In addition, other parameters were obtained from the I–V curves, such as the density current, saturation current, series resistance, threshold voltage, and ideality factor. Also, capacitance–voltage (C–V) characteristic curves allowed the determination of the following parameters: depletion width, built-in voltage, and donor concentration. According to the results, such n-type CdS/p-type ZnTe heterojunctions with rectifying behavior could find potential applications in the development of photodetectors by modifying the difference in carrier concentration between the two materials.
