El demonio dentro: reflexiones acerca de las identidades sexo/genéricas a la luz de un relato trans
Authors: Ramírez Pavelic Mónica , Contreras Salinas Sylvia
Published: July 2023

El objetivo de la investigación es identificar algunos elementos que se dan cita en la conformación de la identidad de un sujeto transexual masculino. Se utiliza para ello un diseño de investigación cualitativa, mediante estudio de caso y análisis de discurso. Desde los resultados surgen seis categorías: diferencia, tránsito, especialistas, confusión, nombre y rabia. A partir del discurso de Víctor se vislumbra la adopción de prejuicios culturales y modelos normalizantes que se encontrarían mayoritariamente al servicio del poder hegemónico. Se concluye en la urgencia de recoger elementos que permitan deconstruir y reconstruir el concepto de diversidad.
La imaginación poética de Olga Costa y José Chávez Morado en Cuautla: el agua, el nacimiento de la ciudad y las sirenas
Authors: Comisarenco Mirkin Dina
Published: July 2023

En el presente trabajo se analiza el ciclo mural de Olga Costa y José Chávez Morado, realizado en el Balneario Agua Hedionda de Cuautla, Morelos en 1952, obra que permite observar algunas de las diferencias temáticas y estilísticas de cada uno de los miembros de la pareja de artistas de forma paradigmática. Apoyándome en algunos conceptos de Gaston Bachelard en su obra clásica El agua y los sueños: ensayo sobre la imaginación de la materia (1942), en el texto interpreto los imaginarios de los artistas en sus representaciones sobre el agua. Considerando sus visiones individuales en torno a  la conceptualización y a la ensoñación del motivo del agua, se concluye que, para conocer el movimiento muralista mexicano en todo su alcance, es necesario integrar al muralismo femenino que complementa y enriquece al fenómeno cultural del movimiento creado originalmente con la intención de democratizar el arte.

Authors: Nso-Mangue María Lourdes , Malik-Liévano Beatriz , Llanes-Ordóñez Juan
Published: July 2023

La ausencia de la orientación en el sistema educativo ecuatoguineano data desde la colonia española. En el día de hoy, la orientación se reconoce como un derecho de todo alumnado. El objetivo de la investigación de este artículo es diagnosticar las necesidades de orientación en estudiantes universitarios de Guinea Ecuatorial, previas a su acceso a la universidad, y así, presentar sus resultados a las autoridades educativas por si creen conveniente diseñar propuestas de implantación de servicios de orientación en esta población estudiantil. Se utilizó un enfoque cuantitativo no experimental, exploratorio-descriptivo, a través de una encuesta. La muestra del estudio está compuesta por 404 estudiantes de la Universidad Nacional de Guinea Ecuatorial. El instrumento de la recogida de información es un cuestionario de necesidades de orientación universitaria del alumnado elaborado para este fin. En los resultados descriptivos se constata que existe poca información respecto a la elección de la carrera, asimismo, de la carrera matriculada, se presenta diversidad de problemas académicos, y de insatisfacciones con los estudios actuales. Lo anterior significaría que este grupo de estudiantes presentaba necesidades de orientación académico-profesional en la elección de su carrera universitaria, y necesidades académicas y personales durante sus estudios en la universidad. Los resultados de esta investigación revelan una preocupación por atender las necesidades y dificultades que enfrentan estudiantes ecuatoguineanos a lo largo de su formación universitaria.
feminismo en la literatura ecuatoguineana: una aproximación al estudio socioeducativo de la novela Ekomo de María Nsue Angüe
Authors: Bituga-Nchama Pedro Bayeme , Nsue-Nsá Marcelo Beká , Ayíngono-Edú María Soledad , Hichaicoto-Topapori Anita
Published: July 2023

El propósito de este artículo es estudiar el pensamiento feminista en la literatura ecuatoguineana, a partir de una aproximación al estudio socioeducativo de la novela Ekomo de María Nsue Angüe, la primera novela escrita por una mujer en la historia de la literatura ecuatoguineana. El problema de investigación se centra en la poca difusión académica que tiene el estudio del pensamiento feminista de la novela Ekomo dentro de la literatura ecuatoguineana en particular y en general de la de la literatura del mundo hispánico. Sin embargo, es importante estudiar la perspectiva feminista de esta novela para conocer su contenido socioeducativo para impulsar cambios socioculturales que permitan una sociedad más equitativa e inclusiva. El método utilizado para este análisis es el descriptivo, fundamentado en la metodología cualitativa que ha permitido analizar los datos obtenidos con el cuestionario realizado, y cuyos principales resultados ponen de manifiesto que la novela Ekomo es feminista, porque refleja las incoherencias de los discursos masculinos, así como las injusticias y asimetrías de las relaciones de género en la sociedad ecuatoguineana.
Las investigaciones existentes sobre esta novela no se centran en señalarla como una obra feminista por su componente socioeducativo para la sociedad ecuatoguineana. Por eso, la solución que proponemos al problema está en estudiar esta novela como feminista porque ayuda a reivindicar desde la literatura el abandono de prácticas culturales aberrantes. Por tanto, es fundamental que una obra de esta naturaleza tenga más difusión desde el ámbito académico para que se conozca su contenido pedagógico.

Abstract. Workplace telepressure is defined as the preoccupation and urge to immediately respond to work-related asynchronous messages in the form of ICT during private hours and working hours, (Barber et al., 2019). This demand to promptly respond to messages can hinder resource recovery and lead to poor well-being, such as burnout (Maslach & Leiter, 2008; Sonnentag & Fritz, 2015). Burnout is a feeling of emotional exhaustion, physical exhaustion, and cognitive fatigue resulting from the gradual depletion of an individual's intrinsic energy sources that occur over time due to work (Shirom 2005). This study aims to determine whether or not Workplace Telepressure contributes to Burnout, as well as to see how big this contribution is. This research is a quantitative research with a causality correlation approach. Using non-probability sampling technique with accidental sampling technique (convenience sampling). Respondents to this study consisted of 30 resident doctors who were pursuing a Specialist Medical Education Program at the Department of Physical Medicine and Rehabilitation, University of Padjadjaran. Using the Workplace Telepressure measurement tool from Barber and Santuzzi (2015) which has been adapted by Parahyanti and Hutama (2022), and the Shirom-Melamed Burnout Measure (SMBM) (2018) which has been adapted by researchers. The results of this study indicate that Workplace telepressure contributes significantly to burnout by 15.2%.

Published: July 2023

Abstract. Problems at the research location indicate that production has not been achieved, causing high mining operational costs. The aim of this research is to increase production targets for operational costs incurred using the rupiah exchange rate with the assumption that 1$ = Rp. 14,300. The research method uses linear programming and the bunching effect. Data collection was carried by calculating the number of available mining operational tools and cycle time data is taken as much as 270 data on 3 mining fleets. The actual productivity generated is 328.49 BCM/hour with an actual production cost of $2.35 USD/BCM with a predetermined target of 500 BCM/hour. The results of the actual conditions need to be corrected by optimizing the number of conveyances to be used using the POM for Windows application, namely the number of conveyances used is 10 units with a production of 520.22 BCM/hour and a production cost of $1.6 USD/BCM. The results showed that the use of 10 units of means of transportation resulted in optimal production with minimum costs compared to the use of 9 units of means of transportation. The loss of time experienced by the transportation equipment due to the bunching effect is 7 hours/month due to differences in engine power on the transportation equipment, different operator skills, undulations street and puddles on the road surface, non-ideal mine road geometry.

Abstract. Research activities were carried out at PT XYZ West Java. One of the negative impacts of blasting activities that can damage the environment is ground vibration. If the vibration generated by blasting activities exceeds a predetermined threshold value, it can result in damage to nearby building structures. The purpose of this research is to determine the explosive charge per delay in controlling ground vibration due to blasting which refers to primary data and secondary data as the research method being carried out. Vibration analysis was carried out based on the Indonesian National Standard (SNI) No 7571 of 2010 by identifying building classes, namely Class 2 buildings that have a PPV value of 3 mm/s and a PPV threshold value for companies, namely 2 mm/s. Based on the results of the analysis that has been carried out between the PVS and SD values, the constant value (K) obtained is 1883.9 and the exponential site (e) is 1.824. The predicted PPV values generated in Leuwidendeng Village are 0.06 mm/s and 0.08. While the predicted PPV values in the office are 0.22 mm/s and 0.48 mm/s, and the predicted PPV values in the explosives warehouse are 0.57 mm/s and 1.97 mm/s. The recommended explosive charge per delay is optimal for PPV 2 mm/s at a distance of 200 meters, namely 22 kg/hole and at a distance of 550 meters using an optimal explosive charge of 137 kg/hole.

The quality of an academic institution is influenced by its website. E-learning, as a type of website used for learning, offers flexible learning opportunities. In order to enhance the effectiveness of e-learning services, it is necessary to evaluate and identify areas for improvement. This research aims to evaluate the quality of learning using the webqual 4.0 method and Importance Performance Analysis (IPA) to determine gaps and prioritize areas for future improvement. The variables examined in this study include usefulness, information quality, and service interaction quality. A qualitative descriptive design was employed, and data suitability was analysed using the webqual and IPA methods. The research data, consisting of numerical values, was collected through interviews and questionnaires administered to faculty members and students via google form. The evaluation scores for usefulness, information quality, and service interaction quality were found to be 72,9%, 75%, and 74,35%, respectively, indicating good quality. The gap analysis revealed a value of -0,07, suggesting that the e-learning website does not fully meet user expectations. The IPA results showed that quadrants III and IV require improvement due to their low performance, as this can affect the level of importance attributed by users to those attributes.

Meteorologists are experiencing many challenges in the reliable forecasting of the track and intensity of tropical cyclones (TC). Uses of the potential vorticity (PV) technique will enrich the current forecasting system. The use of PV analysis of TC intensification over the North Indian Ocean (NIO) is rare. In this study, the authors analyze the behaviour of upper-level PV with dynamic parameters of TCs over NIO. The authors used NCEP FNL reanalysis 1 × 1 degree data as input in WRF model version 4.0.3 with one-way nesting between the parent and child domains. The authors used a coupling of the Kain-Fritsch (new Eta) scheme and the WSM 6-class graupel scheme as cumulus and microphysics options to run the model. The authors found that at least one potential vorticity unit (PVU) (1 PVU = 10–6 m2 s –1KKg–1) upper PV is required to maintain the intensification of TC. Larger upper PV accelerates the fall of central pressure. The high value of upper PV yields the intensification of TC. The wind shear and upper PV exhibited almost identical temporal evolution. Upper PV cannot intensify the TCs at negative wind shear and shear above the threshold value of 12 ms–1. The upper PV and geopotential heights of 500 hPa change mutually in opposite trends. The upper PV calculated by the model is comparable to that of ECMWF results. Therefore, the findings of this study are admissible.

An important pest that attacks long bean plants is the green ladybug (Nezara viridula L.). Green ladybug attacks cause the young pods to become empty and deflated, because the seeds do not form and the pods fall. Several field tests showed that yield loss by one adult N. Viridula per two plants caused pod damage by 49%.  The aim of the study was to determine the color and height of the traps that were effective in trapping the green ladybug (Nezara viridula L.). The study was conducted in Taeno hamlet, Rumah Tiga Village, Teluk Ambon District from April to June 2022. The study used a Randomized Block Design (RAK) with 2 treatments. The first treatment was a trap color consisting of 3 levels, namely red, yellow and green. The second treatment was the height of the trap which consisted of 3 levels, namely the height of the trap 1 m, 1.5 m, and 2 m above ground level. The results obtained information that the interaction between the red trap color and the 1.5 m trap height had a significant effect on the number of green ladybug populations trapped in the 1st to 4th observations. -3 is found in the use of yellow traps, while in the 4th observation the interaction between green traps with a trap height of 1.5 m.
