Authors: CARRILLO BARBOSA Yazmid Adriana , MORENO LÓPEZ William , GUZMÁN RINCÓN Alfredo
Published: July 2024

El objetivo principal de este estudio es evaluar la rentabilidad y los riesgos asociados al portafolio del nexo agua, energía y alimentos (AEA) en el escenario pospandemia. Para ello, se empleó una metodología cuantitativa y trans- versal, basada en el análisis de una variedad de commodities que representan estos sectores, tales como bonos de agua de California; petróleo crudo Brent, gas natural, maíz, soja y café. El análisis se realizó mediante un algoritmo desarrollado en Python, enfocado en evaluar la rentabilidad, el riesgo del portafolio y la Frontera de Eficiencia de Markowitz. Los resultados mostraron que, aunque existen oportunidades de rentabilidad en el portafolio del nexo AEA, también se presentan riesgos significativos para la obtención de dicha rentabilidad. Un hallazgo clave del es- tudio es que, a pesar de la creciente demanda de recursos eficientes y sostenibles, la inversión en estos sectores requiere una gestión estratégica y considerada. Se sugiere la necesidad de una cuidadosa selección y diversifi- cación del portafolio, alineando las inversiones con principios de sostenibilidad para garantizar su viabilidad a largo plazo. El estudio concluye destacando la importancia de desarrollar modelos predictivos más robustos y aboga por investigaciones futuras para un análisis más integral de las dinámicas entre agua, energía y alimentos y su impacto en los mercados financieros.

Published: July 2024

Este estudio investiga el impacto del diseño gráfico en la percepción de la movilidad estudiantil en la Universidad UTE, Quito, con el propósito de determinar si los carteles gráficos pueden persuadir a los jóvenes a elegir medios de transporte públicos o alternativos en lugar de vehículos privados. En primera instancia, se llevaron a cabo encuestas a una muestra de estudiantes con un nivel de confianza del 95% y un margen de error del 5% para comprender sus hábitos y necesidades de movilidad. Los resultados indican que, aunque la mayoría utiliza transporte público, preferirían tener un vehículo privado si tuvieran la oportunidad. Luego, se presentó una muestra de carteles diseñados por estudiantes de Diseño Gráfico, seguido de entrevistas a un grupo de participantes para evaluar su influencia en la elección de transporte. Los resultados muestran que la mayoría de los estudiantes entrevistados cambiaron su perspectiva hacia la movilidad, considerando más seriamente el uso de transportes alternativos para abordar la contaminación ambiental y los problemas de movilidad. Aunque este estudio no es concluyente, nuestros hallazgos sugieren que los carteles gráficos lograron influir en la percepción de los estudiantes, resaltando así la importancia del diseño gráfico como herramienta para abordar problemas sociales.
Entre mandatos y desobediencias
Authors: Diez Manuelita
Published: July 2024

El envejecimiento plantea grandes retos para la provisión de cuidados así como para garantizar condiciones de vida dignas para las personas mayores (Arias, 2015; OEA, 2015). En Argentina, en 8 de cada 10 hogares en los que viven personas mayores, su cuidado es provisto por familiares generalmente de género femenino (BID, 2020), mostrando esto la necesidad de producir conocimiento que permita promover la corresponsabilidad de género.
El artículo presenta los resultados de un estudio cualitativo y transversal realizado entre octubre y diciembre del 2023 con el objetivo de describir las representaciones sociales, prácticas y sentidos vinculados a la provisión de cuidados no remunerados en varones de nivel socioeconómico medio que vivían en la Ciudad de Buenos Aires y que cuidaban a personas mayores. La muestra fue no probabilística e intencional y estuvo conformada por 10 varones de entre 18 y 40 años. El instrumento de recolección de datos fue una entrevista semiestructurada. El análisis se realizó mediante la segmentación y codificación de los datos, incorporando el enfoque de género. Como resultado se obtuvo que las representaciones sociales de reciprocidad y responsabilidad sobre la que se asentaban los cuidados resultaban también en valoraciones positivas de los varones acerca de sí mismos. Los vínculos entre los varones y las personas cuidadas fueron caracterizados como “intensos”, resaltando la cercanía y la amorosidad pero también la necesidad de distancia. Se identificó además la necesidad de incorporar en los espacios de trabajo estrategias y políticas que garanticen a los varones licencias de cuidados.
La diáspora africana en Ecuador: memorias, conexiones e historias olvidadas
Authors: Guerrero Maruri Fernando
Published: July 2024

El artículo resalta la importancia de promover el estudio de la diáspora africana en Ecuador y la región, al repasar bibliografía de diferentes partes del mundo, busca convertirse en un disparador para quienes cursan carreras de pre y posgrado con intereses en la inclusión del tema de la esclavitud en su vasta complejidad, de una forma más integral y multidisciplinaria.
Partiendo de los estudios de Lucio Ferreira (2009) en Brasil, se realiza una revisión crítica y discusión bibliográfica deductiva que vincula ideas, concepciones teóricas y conceptos con proyección a la construcción sostenida de evidencia empírica (Sautu, 2006, p. 87), en donde, autores de distintos continentes recogen diversas experiencias investigativas de museos y sitios patrimoniales vinculados a la diáspora africana. De frente, al reducido número de estudios de largo aliento, alcance e impacto que se encuentran sobre Ecuador.
El presente trabajo mapea posibilidades de aporte en esa línea de investigación en búsqueda de los excluidos de la historia oficial sin una representación real en la memoria de su país. La revisión y análisis de bases de datos de producción científica concluye que el Estado y los criterios de investigación sobre la versión oficial ha retrasado y permitido la pérdida de tiempo y evidencias cruciales para comprender el pasado y su impacto en la sociedad actual.

Abstract
The European Commission asked EFSA for a risk assessment on small organoarsenic species in food. For monomethylarsonic acid MMA(V), decreased body weight resulting from diarrhoea in rats was identified as the critical endpoint and a BMDL10 of 18.2 mg MMA(V)/kg body weight (bw) per day (equivalent to 9.7 mg As/kg bw per day) was calculated as a reference point (RP). For dimethylarsinic acid DMA(V), increased incidence in urinary bladder tumours in rats was identified as the critical endpoint. A BMDL10 of 1.1 mg DMA(V)/kg bw per day (equivalent to 0.6 mg As/kg bw per day) was calculated as an RP. For other small organoarsenic species, the toxicological data are insufficient to identify critical effects and RPs, and they could not be included in the risk assessment. For both MMA(V) and DMA(V), the toxicological database is incomplete and a margin of exposure (MOE) approach was applied for risk characterisation. The highest chronic dietary exposure to DMA(V) was estimated in ‘Toddlers’, with rice and fish meat as the main contributors across population groups. For MMA(V), the highest chronic dietary exposures were estimated for high consumers of fish meat and processed/preserved fish in ‘Infants’ and ‘Elderly’ age class, respectively. For MMA(V), an MOE of ≥ 500 was identified not to raise a health concern. For MMA(V), all MOEs were well above 500 for average and high consumers and thus do not raise a health concern. For DMA(V), an MOE of 10,000 was identified as of low health concern as it is genotoxic and carcinogenic, although the mechanisms of genotoxicity and its role in carcinogenicity of DMA(V) are not fully elucidated. For DMA(V), MOEs were below 10,000 in many cases across dietary surveys and age groups, in particular for some 95th percentile exposures. The Panel considers that this would raise a health concern.

LA CATÁSTROFE CLIMÁTICA COMO PROFECÍA SECULAR Y MILENARIA
Authors: López-Lemus Luis G.
Published: July 2024

El movimiento por el cambio climático es una entidad cultural poderosa. No afirma ni niega la realidad de su narrativa central, que corresponde a la ciencia decidir y, sin embargo, es la cultura la que explica el poder y la prevalencia de su narrativa, las respuestas políticas y sociales a ella y la aparente voluntad de muchas personas para incurrir en costos inmensos con el fin de evitar una supuesta amenaza existencial aún cuando nuestra capacidad para alterar sus consecuencias es cuestionable. Esta narrativa emplea el miedo como un poderoso motivador que se inculca desde la niñez y cuya condena apocalíptica se determina de antemano por la desobediencia colectiva, mientras que la salvación se promete para los píos y arrepentidos que cumplan con sus onerosas disposiciones, muchas de ellas inútiles. En 1983, Michael Barkun, hoy profesor emérito de la Universidad de Syracuse en Nueva York, publicó un puntilloso ensayo que identifica proféticamente el surgimiento de un “nuevo apocalipticismo” en el tan politizado discurso mediático de nuestro tiempo. Se comparten extractos selectos del mismo, traducidos libremente, supeditándolos a los debates públicos vigentes sobre el tema, particularmente enfáticos en sus catastróficas proyecciones y nefastas consecuencias

Authors: Abbas Amjed H. , Jasim Ahmed Hussein , Hammoud Samir S. , Al-Hindy Hayder Abdul-Amir Makki , Alesawi Kareem Nasir Hussien
Published: July 2024

Background: Several reviews have shown a pro-inflammatory role of Interleukin-17 (IL-17) level and have an association to numerous inflammatory illnesses, like rheumatoid arthritis, allograft rejection, systemic lupus erythematosus, and asthma. The T helper-17 (Th-17) cellular fraction of CD4+ T-cells that have been involved as the principal pathogenic cells in a variety of illnesses that has an autoimmune base, produce the cytokine interleukin-17A (IL-17A).
Asthma is a chronic inflammatory disease associated with recurrent airways obstruction that is relieved either spontaneously or with medications. Both innate and adaptive immunogenic cells in asthma collaborate with respiratory epithelium to generate "bronchial hyper-reactivity (BHR)". To determine the role of IL-17 in asthmatic patients and the relationship between IL-17 and asthma severity.
Results: IL-17 revealed a significant (p-0.001) rise in the values of IL-17 among asthmatic cases (mean = 176.6) compared to healthy controls (mean=22.55). The difference in IL-17 levels between severe and mild asthma was also significant, with a p-value of 0.005.
Conclusion: This study suggests that there was a significant difference in the concentrations of IL-17 between asthmatics and healthy control (p-0.001). In severe asthma, IL-17 levels are significantly (p-0.005) higher than in mild/moderate asthma.
Embedding of Neutrosophic Graphs on Topological Surfaces
Authors: Majeed Amir Sabir
Published: July 2024

Background:
 A planar graph (PG) is a graph with no intersecting edges. Particular to both crisp and neutrosophic graphs (NG) is the planar graph, in contrast to crisp planar graphs. NPGs allow for the intersection of neutrosophic edge NEs, since the value of planarity in these graphs is the degree of planarity of the intersected NEs. The NPGs are often represented on a flat surface.
Materials and Methods:
 This study discusses how to embed NGs on surfaces such as spheres and m-toruses by defining the degree of intersection of the neutrosophic edges of NGs with finding the faces on the given graph structures using Euler's theorems. Here, the proofs of Euler's theorems help us find, given the total NFV of G, the interval containing that value.
Result:
 As result of this work obtained that for any two isomorphic planer graphs, they have the same planarity value. For any neutrosophic planer graph with f = (1,1,1) can be embedded in the plane if it can be embedded in the sphere and according to NPGs, for planar and spherical surfaces, equivalent theorems to Euler's formula are proved and shown.
Conclusion:
 It concludes that by using neutrosophic sets and crisp graphs to construct neutrosophic graphs with the benefit of Euler’s theorem, it can provide the concept of embedding neutrosophic graphs in different topological surfaces such as a plane, sphere, and m-torus.

The topic of previous research with the research now proposed by researchers is interconnected, which remains on the creative products of Sekarbela pearl crafts in Mataram City. This study is to analyze customer attitudes which are important aspects of consumer behavior that periodically need to be analyzed and assessed to ensure the continuity of purchases and loyalty of their customers. The result shows that the attitude of consumers of pearl creative products was positive. These results are obtained from the process of analyzing a number of attributes inherent in the product such as durability, design, pearl grain quality, specifications, frame material, aesthetic value, and product price. The value of this attitude needs to be increased by marketers to ensure the survival of the business that has become the icon of Mataram City.

Published: July 2024

Pictures obtained from a chest X-ray can assist in diagnosing and screening various illnesses, including pneumonia, mass, lung opacity, TB, and nodules. The convolutional neural network (CNN) has been devised to predict pulmonary disease. In this investigation, we classify lung disease based on pictures from chest X-rays using a technique known as transfer learning. This method was chosen because it allows us to make more accurate diagnoses. Transfer learning has proven effective for detecting diverse anomalies in limited medical imaging datasets, leading to notable outcomes. This study involves utilizing a dataset comprising a collection of chest X-ray photos obtained from the Kaggle website, including nine different lung diseases (COVID, mass, effusion, lung opacity, nodule, pneumonia, pneumothorax, pulmonary fibrosis, and tuberculosis), as well as images of individuals without any lung ailments. The objective is to employ several transfer learning models (VGG19, Inception V3, Efficient Net V2m, Xception, Mobile Netv3, and Dense net201) to train these images, classify them, and then select the most influential Model for addressing this task. Most models yielded promising results, particularly dense net201, mobile net, and VGG19, which achieved more effective yields with 95.49%, 94.89%, and 93.69% accuracy rates, respectively.

There is a great need of internet applications that involves data to be sent in an extra safe way. Steganography and cryptography help in providing data safety. Steganography hides the existence of message by inserting data in some other digital media and Cryptography transforms data in to cipher object that can be in unreadable form to normal user. To resume the defense of data defeating and communication over internet, this paper suggests a hybrid heuristic, integrating a genetic algorithm and steganography technique to efficiently solve this problem.
Computational results show that the suggested technique can significant improvement the performance of a genetic algorithm for this problem, this was proven by the results of the comparison between the suggested technique and several other proposed systems. Genetic Algorithm is used for pixel variety of image where secret data is to be hidden so that detection of secret data become multifarious

Objective: To compare the cold steel method and bipolar diathermy in tonsillectomies in terms of post-tonsillectomy hemorrhage. Study Design: Randomized Controlled Trial. Setting: Department of ENT, Head & Neck Surgery, Ayub Teaching Hospital, Abbottabad. Period: 29th October 2020 to 1st June 2022. Methods: A total of 102 patients of both genders with ages 3 to 59 years undergoing tonsillectomy were included. Patients undergoing antiplatelet therapy, experiencing bleeding diathesis, possessing a high anesthetic risk, having uncontrolled medical conditions, suffering from anemia, or currently dealing with acute infections were not included in the study. Patients were divided into two groups A & B. Group A patients were operated by the Cold steel method and Group B were operated by Bipolar diathermy. All the surgeries were performed by the same surgical team. Both tonsils were fully exposed by Boyl Devi's mouth gag under general anesthesia. Complete removal of both tonsils was done with the Cold steel method in group A and by using Bipolar diathermy in group B. Post-operative hemorrhage (occurring 24 hours after surgery) without the necessity to return to the operation theatre for intervention was assessed. Results: The mean age of patients in group A was 20.0 ± 13.83 years and in group B was 19.12 ± 13.17 years. The majority of the patients 79 (77.45%) were between 3 to 30 years of age. Out of 102 patients, 63 (61.76%) were males and 39 (38.24%) were females with male to female ratio of 1.6:1. Frequency of secondary hemorrhage in Group A (cold steel method) was found in 01 (1.96%) while in Group B (bipolar diathermy) was 06 (11.76%) (p-value = 0.050). Conclusion: This study concluded that the frequency of post-tonsillectomy hemorrhage is higher in patients operated by bipolar diathermy as compared to the cold steel method.

Objective: To find out the functional outcomes as per Harris hip score (HHS) among patients of pertrochanteric fractures undergoing dynamic hip screw (DHS) versus proximal femoral nail anti-rotation (PFNA) at a Tertiary care hospital. Study Design: Non-randomized Controlled Trial. Setting: Orthopedic Section, Department of Surgery, Agha Khan University Hospital, Karachi, Pakistan. Period: 1st August 2023 to 30th January 2023. Methods: A total of 40 patients of age 18 and older with confirmed pertrochanteric fractures were non-randomly allocated to ether fixation with DHS or PFNA. Intra-opeative blood loss and duration of surgery were recorded. The functional outcome assessment was assessed using HHS. Results: In a total of 40 patients, 31 (77.5%) were female. The mean age was 67.63±15.13 years (ranging between 23 to 89 years). The most common mechanism of fall was tipped over loose carpet, noted in 17 (42.5%) patients.  The mean intra-operative blood loss in DHS and PFNA groups were 73.75±20.06 ml, and 72.75±23.14 ml, respectively (p=0.885). The mean duration of surgery were 76.6±14.7 minutes, and 115.1±18.3 minutes in DHS and PFNA groups, respectively (p<0.001). Excellent, good, fair, poor, and failed outcomes were reported in 3 (7.5%), 17 (42.5%), 6 (15.0%), 10 (25.0%), and 4 (10.0%) patients respectively. When both groups were compared for outcomes, no statistically significant differences were observed (p=0.339). The mean HHS in DHS, and PFNA groups were 75.26±11.41, and 73.46±14.57, respectively (p=0.666). Conclusion: Functional outcomes as per HHS were relatively similar with DHS and PFNA approaches in patients with pertrochanteric fractures.
