Impacto de la crisis de 2020 en la economía mexicana: un enfoque de insumo-producto con inoperabilidad
Authors: Solís y Arias J. Valentín , García Helio , Márquez José Manuel , Hernández Victor H.
Published: October 2022

En el texto se presentan dos modelos insumo-producto con inoperabilidad que analizan los efectos de la pandemia de Covid-19 en México, ambos utilizan desarrollos metodológicos recientes en los que se realizaron aportaciones en su especificación. El primero, un modelo estático, genera un índice de vulnerabilidad de las ramas económicas, produciendo su prelación para la atención con instrumentos de política económica. El segundo, un modelo dinámico, estima posibles trayectorias de recuperación económica de los sectores, su posible duración, y sus capacidades de resiliencia frente a fenómenos de persistencia de la pandemia. Los modelos se ajustan a los indicadores de corto plazo que produce el INEGI, reflejando un comportamiento heterogéneo entre los sectores; algunos con una tendencia de mediano plazo a no regresar a su capacidad productiva normal.
Extractivismo de capacidades: el caso del sector de software y servicios informáticos argentino
Authors: Baum Gabriel , Moncaut Nicolás , Robert Verónica
Published: October 2022

El sector de software y servicios informáticos (SSI) argentino lleva dos décadas de actividad impulsado por políticas públicas y la subcontratación internacional. Sin embargo, en la actualidad el crecimiento del sector está estancado. Este freno se debe a un extractivismo de capacidades que opera por tres vías: precios-salarios, formación y financiera. La primer vía, la explica la creciente competencia por costos que resulta en contracciones de salarios y beneficios. La segunda, la formación de capacidades que se reorienta a los requisitos de la demanda internacional en competencias estandarizadas. Y la tercera, la valorización financiera de los emprendimientos. El artículo construye un conjunto de información estadística que permite describir y documentar este fenómeno en el caso argentino.

Authors: Guerrero Rodríguez Lilia Esther , Pérez Vences Mayté , Dajer Torres Regina , Villalobos López Marilú , Méndez Jiménez Yesika
Published: October 2022

El aprendizaje del inglés como segunda lengua es fundamental en la formación universitaria. La presente investigación tuvo como objetivo analizar las estrategias de aprendizaje que emplean los alumnos de la Facultad de Pedagogía de una universidad en México para el desarrollo de competencias en el idioma inglés. Para lograr ese objetivo, se acudió al paradigma cualitativo y el método fenomenológico, a través de la aplicación de entrevistas a un grupo de 15 estudiantes de la Facultad de Pedagogía, siguiendo un protocolo de entrevistas semiestructurado. Se establecieron tres categorías deductivas a priori para orientar las entrevistas: Conocimientos previos, Afinidad para estudiar el idioma e Información e incorporación de estrategias de aprendizaje. Los discursos fueron analizados mediante el procedimiento de análisis categorial, lo cual permitió identificar subcategorías emergentes. Los resultados muestran que los estudiantes no aplican conscientemente estrategias de aprendizaje (cognitivas, metacognitivas y/o socioafectivas) y tampoco aprovechan el entorno didáctico existente para desarrollar un proceso de aprendizaje autónomo del inglés.

Published: October 2022

Lovastatin is a naturally produced 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase enzyme inhibitor- used for treating hypercholesterolemia. It was the first statin drug which was approved by the United States Food and Drug Administration (USFDA). In the current study, endophytic fungus Fusarium nectrioides (MH173849) isolated from Euphorbia hirta L. was used for the production of lovastatin. Four different culture media indicated as M1, M2, M3 and M4 were used for the initial production of lovastatin. Liquid cheese whey was used as nitrogen source. Growth morphology of fungi was investigated using Scanning Electron Microscopy analysis. Also, parameters like temperature, pH, inoculum size, incubation time, and RPM were optimized for the obtaining highest lovastatin production. Among the four media, M4 was found to produce the maximum concentration of lovastatin. Parameters such as temperature of 28°C, pH 6, RPM – 180 rpm and inoculum size of 5 x107 spores/mL were optimal for the production of lovastatin by F. nectrioides (MH173849).

Authors: Kumar Tarun , Ali Hamid
Published: October 2022

Abstract: Modern telecommunication systems require antenna with wider bandwidth and smaller dimensions. Various antennas for wideband operation have been studied for communication and radar system. The fractal antennas are preferred due to small size, light weight and easy installation. In this paper a parabolic planer monopole antenna using the Koch based fractal geometry is introduced for multiband operation. The design achieves a good input impedance match and linear phase of S11 throughout the pass band (1—3.5 GHz and -10dB criterion for impedance bandwidth). The use of fractal pattern in this paper provides a simple and efficient method for obtaining the compactness. Various bands are 1.2GHz and 2.3 GHz. The antenna has a promising peak gain of 5.3 dBi with 5.5 dBi directivity in pass band. The pass band has VSWR in between 1 and 2. The proposed antenna has enormous high bandwidth (1.124GHz) that suits the many wireless applications like WLAN, Bluetooth, analog radio and GPS system and it can also be used for microwave devices communication.

The effect of parents' emotional support and attachment perceived by adolescents on their experiences of school violence: Mediating effect of parents' participation in school activities
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Lim Sojin , Joo Hyunjung
Published: October 2022

Objectives The purpose of this study is to examine the effects of positive factors, which are parental emotional support, and negative factors, such as the type of alienation, during adolescence, on the adolescents' experiences of school violence. The purpose of this study is to more clearly approach the role of parents required during adolescence by analyzing the mediating effect of parental participation in school activities.
Methods For this purpose, data from the 6th year of the Korean Educational Longitudinal Study (2013) of the Korea Educational Development Institute was used. The data for students were extracted from adolescents' experiences of victimization of school violence, emotional support from parents, and marginalized variables among parental attachment, and the degree of parental participation in school activities was extracted from the data for parents. The subjects of this study were 5,707 high school first grade students and their parents' data.
Results First, the emotional support of parents perceived by adolescents did not have a significant effect on their experiences of school violence. The more adolescents felt alienated from their parents, the more likely they were to experience school violence. Second, both parents' emotional support and alienation perceived by adolescents were found to be variables that significantly affected parents' participation in school activities. When the emotional support of parents perceived by adolescents was high, parents' participation in school activities was high, and the higher the degree of parental alienation, the higher the parent's participation in school activities. Third, it was found that parents' participation in school activities completely mediates between the emotional support of parents and the adolescent children's experiences of school violence, and partially mediates between the alienation among parents and the adolescent children's experiences of school violence.
Conclusions The negative relationship between adolescent children and their parents appears to have an effect on the children's negative behavior in school life, so measures to reduce adolescents' experiences of school violence require school education and a cooperative effort with parents. High participation in school activities as parents during adolescence negatively affects adolescents' experiences of school violence, so a parent's role that respects adolescent autonomy is required.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Kang Kyung Hee , Choi Woongyoung
Published: October 2022

Objectives The purpose of this study is to verify the mediating effects of dysfunctional communication patterns on the relationship between adverse childhood experiences(ACEs) and marital satisfaction.
Methods To this end, a survey was conducted on 235 people aged 20 to 69 who are currently married, and 221 data were used for the final statistical analysis. For the collected data, descriptive statistics, reliability analysis, ANOVA and correlation analysis were performed using the SPSS 23.0 statistical program, and hierarchical regression analysis was performed to verify the influence of control variables. Also, Process Macro v4.0 Model 4 was used to analyze the mediating effects.
Results It was found that adverse childhood experiences and dysfunctional communication patterns directly affect marital satisfaction, and dysfunctional communication patterns completely mediate between adverse childhood experiences and marital satisfaction. In addition, among the sub-variables of the dysfunctional communication patterns, criticism, contempt, and stonewalling completely mediated between adverse childhood experiences and marital satisfaction, and defensiveness partially mediated.
Conclusions The results of this study showed that rather than directly predicting marital satisfaction through adverse childhood experiences, those who used a lot of dysfunctional communication patterns among those who had adverse experiences in childhood perceived marital satisfaction as low. Therefore, in the therapeutic intervention to improve marital satisfaction in the couple therapy counseling field, it may be more effective to examine whether the couple had adverse childhood experiences in their original family and whether the couple engage in dysfunctional communication patterns of criticism, defensiveness, contempt, and stonewalling in conflict situations, and focus on causes and alternatives.

A Qualitative Study for the Effective Design and Practice of Creative Experience Activities of the 2022 Revised Curriculum: A Critical Analysis into Elementary Teachers’ Experiences
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Jung Jung-Hoon , Jo Jae-seong
Published: October 2022

Objectives This study was to understand how creative experience activities are currently being operated in elementary schools and to find ways of the effective application and improvement of the creative experience activities of 2022 Revised Curriculum. In particular, the purpose of this study was to focus on how the domain and content of creative experience activities are being applied in elementary schools, and whether the creative experience activities are being revised by properly reflecting the opinions and experiences of teachers.
Methods An qualitative research was used for the study, including in-depth interview and document analysis. 10 public elementary school teachers were invited as research participants. The researchers collected data about how elementary school teachers plan creative experience activities, and how they apply the plan. Various school curricula documents were also collected. For the analysis, the researchers followed the process of the comprehensive analysis procedure of qualitative research.
Results First, most of the teachers responded that autonomous activities are a curriculum component when the schools and teachers could freely organize. Yet, in actual operation, the problem of teachers' lack of autonomy was revealed. Second, club activities were found to be the area where teachers' opinions and thoughts were most reflected. However, support for teachers was lacking and, contrary to the original intention, students' opinions were mostly ignored. Third, volunteer activities needed the most improvement among elementary school creative experience activities. Fourth, career activity was the area where teachers showed the greatest difference in perception and practice. Although new attempts and creative classes for effective management of career activities were observed, they were also operated in a way that was most unsuitable for the educational goals of elementary schools or the developmental level of the students.
Conclusions At the elementary school level, teachers believe that creative experiential activities play as important role as the subjects, but in actual practice, they were unable to practice creative experiential activities according to the original purpose of the curriculum. Insufficient support and interest of teachers also hindered the effective implementation of creative experience activities. To solve the problems, solutions such as appropriate content distribution and balance between the four domains, restructuring goal statements of each domains, and enhancing teachers’ and students’ autonomy were suggested.

NORMAL VIBRATIONS OF SAGGING CONDUCTORS OF OVERHEAD POWER LINES
Authors: Valiullin Airat , Danilin Alexander , Feldshteyn Valery
Published: October 2022

The phenomenon of self-excitation of thermomechanical vibrations of current-carrying conductors, experimentally discovered by academician A.F. Ioffe, is of practical interest as a possible explanation of the phenomenon of galloping conductors of overhead power transmission lines (OHL) – low-frequency vibrations with frequencies of ~ 1 Hz and with amplitudes of the order of the static conductor sagging. To build the theoretical foundations of this phenomenon, as a special class of self-oscillating systems, it is necessary, first of all, a model of conductor vibrations in the OHL span. With regard to the most studied type of conductor vibrations, high-frequency aeolian vibration, excited by sign-alternating aerodynamic forces from the Karman vortex street, the classical model of a straight string is reasonably applied. However, to study low-frequency vibrations of the galloping type, it is necessary to take into account the effect of sagging of the conductor, the associated elastic tension and, in some cases, the nonlinear nature of the vibrations. The article presents two models for calculating the natural vibrations of sagging conductors (cables) within the framework of the technical theory of flexible threads, assuming the constancy of the tension force along the length. The first model describes linear oscillations of an elastic conductor in the sagging plane. For a system of equations with respect to the displacement components given in natural coordinates, an exact solution of the Sturm-Liouville problem with estimates of the frequency ranges arising is obtained. The second model describes nonlinear vibrations of an elastic conductor in the sagging plane and pendulum vibrations accompanied by an exit from it. The solution of the problem is based on the principle of possible displacements using the Ritz method. The structure of the frequency spectrum and the natural forms of transverse vibrations are studied. The developed models are intended for further investigation of thermomechanical vibrations of conductor and flexible cable systems.
Diversity of the egg tertiary membranes in some elasmobranch species and comments on the actual yolk-sac viviparous reproductive mode
Authors: Oddone Maria Cristina , Capapé Christian
Published: October 2022

After fertilization, elasmobranch eggs (mostly megalecithal) are encapsulated in a tertiary membrane of different complexity, in the oviducal gland. The gross morphological characteristics of this membrane in elasmobranchs are highly variable, attaining it most sophisticates’ forms within the oviparous species. The purpose of this study was to contribute to the knowledge of the elasmobranch tertiary membranes, in both viviparous and oviparous species, and to discuss the relation with their role in protecting the embryos their development. In addition, the limitations of yolk-sac viviparity as a single reproductive mode category are commented, suggesting a new arrangement of taxa within that reproductive mode and new terminology. Data on tertiary membranes in elasmobranchs come from a large number of sources ranging from 1977 to date. Specimens were captured on board of commercial and scientific research cruises, from the following some major geographic regions: South Western Atlantic, South Western Pacific, and different areas of the Mediterranean Sea. In all, our records of tertiary membranes belong to ten species of sharks of five orders; Hexanchiformes, Squatiniformes, Heterodontiformes, Lamniformes, Carcharhiniformes, and eight species of rays and skates, of four orders: Rajiformes, Rhinopristiformes, Torpediniformes and Myliobatiformes. The reproductive modes reported for all this species were both lecithotrophic (yolk-sac viviparity, short single oviparity) and matrotrophic (ovotrophy, placentotrophy, limited and lipidic histotrophy). Six morphological and structural major patterns were detected within the yolk-sac viviparous species (type I to VI); a thin, diaphanous, shapeless membrane; candle capsules; oviparous-like tough egg capsule, and cases where no tertiary membrane was present.
Key macroeconomic indicators of economic growth in the case of developing countries
Authors: Iballi Nazmi , Smajli Remzi , Ziberi Besime
Published: October 2022

The neoclassical Solow-Swan economic growth theory of 1956, also known as the exogenous growth model, advocates for the accumulation of physical capital as an important driver of economic growth in the short run, while technological advancement is the key determinant of economic growth in the long run (Chirwa & Odhiambo, 2016). The main aim of this study is to measure the impact of some key macroeconomic factors, which influence the economic growth of a developing country, in our case, the Republic of Kosovo. This study uses secondary data from The World Bank Indicators for the time period 2010–2020. In this study, the ordinary least squares (OLS) econometric model is employed, the dependent variable used is the gross domestic product (GDP) growth, and the independent variables used are private consumption, remittances, export, and employment. Growth in an economy is measured by a change in the volume of its output or the real expenditure or income of its residents (The World Bank, n.d.-d). The study comes to the conclusion that the OLS model is important under the study circumstances thus the independent variables such as consumption, employment, exports, and remittances have a positive impact on Kosovo’s economic growth measured by GDP. The study comes with further recommendations such as increasing employment, using more effectively the remittances received from the diaspora, and increasing the exports for Kosovo to gain economic growth and sustainability.
A Novel Method to Prove the Four Color Theorem

«Silêncio de luz»: mística musical em Jorge de Sena
Authors: Paixão Ana
Published: October 2022

O processo poiético de Jorge de Sena desvela, com frequência, diálogos semióticos com outras artes. Em obras como Metamorfoses ou Arte de Música, a palavra poética seniana mostra-se como uma «gruta povoada de ressonâncias» , como bem afirma Sophia de Mello Breyner numa carta a Jorge de Sena. A criação tem o seu ponto de partida na experiência estética, na fruição de signos de outras artes, que, depois de capturados, vibram em silêncio. Em permanente semiose peirciana, esses signos serão recriados em palavras habitadas por ressonâncias interartísticas. O «Silêncio de luz»  converte-se numa das etapas fundamentais da poiesis de Sena – é a pausa pregnante, da qual emerge o poema. Vestígios de escutas, resquícios de experiências auditivas ou visuais impregnam esse silêncio criador, onde o dizer é sempre vacilante e contingente: «Da música ao sentido, que palavra / preenche o vácuo de silêncio […]?» . O inexprimível wittgensteiniano revela-se sobretudo em relação à música. Arte alquímica e intangível, que simultaneamente (nos) toca e transcende, que sustenta a harmonia das esferas e sublima a teoria das cordas, numa mística musical insondável: "Se há mistério na grandeza ignota, / e se há grandeza em se criar mistério, / esta música existe para perguntá-lo"
“Busco el nacer de la luz…” Decir el desierto y la sed en la poética de Hugo Mujica
Authors: Campana Silvia Julia
Published: October 2022

La poesía de Hugo Mujica, poeta argentino contemporáneo, nos sumerge en un espacio literario en el cual el silencio, el deseo, el desierto, la sed, el vacío perfilan un camino que conduce al acontecimiento del poetizar. Poeta del silencio que revela honduras de las cuales somos protagonistas, que oscilan entre paradojas: palabra-silencio, desierto y sed, luz y oscuridad, trascendencia e inmanencia, presencia y ausencia, que nos asoman al abismo de belleza y misterio del cual pendemos. La obra de Mujica está atravesada por lo sagrado como lo inaugural, la fuente que conduce al poeta-pensante a cavar hondo en lo más despojado, “allí donde la vida es la de todos, donde desnudos, somos todos un mismo rostro”.  Y su decir es testigo y fruto del diálogo con otros, entre ellos: Juan de la Cruz, el maestro Eckhart, Heidegger. Nos adentraremos en su espacio poético para volvernos escucha de esta hondura y descubrir la tensión que lo rodea, hacia el misterio de lo indecible.
Figuras Femeninas de la Sabiduría y la Justicia en la Obra De Hildegard de Bingen (1098-1179)
Authors: Góngora María Eugenia
Published: October 2022

En esta presentación quiero referirme a la presencia de dos figuras femeninas que tienen un papel importante en la obra de Hildegard de Bingen tal como podemos conocerla gracias a los escritos de dos autores monásticos que trabajaron con sus escritos: su hagiógrafo Theoderich de Echternach y el abad Gebeno de Eberbach, un compilador de su obra profética y apocalíptica.

 En este contexto, me referiré a la presencia de las figuras  Sapientia, la Sabiduría, y la segunda es la Justicia, que no tiene una presencia tan importante como la primera, pero que tiene una voz y un papel  especialmente interesante en el pensamiento apocalíptico de Hildegard.

 Hildegard,  magistra de un convento en Bingen, a orillas del Rhin durante el siglo XII,   fue leída por sus contemporáneos como una visionaria y una profeta,  como intérprete de las escrituras y los acontecimientos en el ámbito  de la Iglesia como institución; por otra parte, la interpretación de su obra hacia fines de la Edad Media y en la temprana modernidad  difiere en buena medida de los fenómenos de recepción más contemporáneos:, más recientemente. Hildegard ha sido ‘leída’ desde la filología, la  historia de la música, la literatura y la filosofía, pero también, a partir de sus escritos médicos, ha sido estudiada y “recreada” desde la ecología, la medicina alternativa y el feminismo. Sus visiones y profecías, por otra parte,  han aparecido  marginalmente en la tradición de los estudios sobre Sofía, la Sabiduría, que han tenido una larga e importante  historia hasta al menos la primera mitad del siglo XX.
Don Quijote ante la caballería espiritual de san Juan de la Cruz
Authors: López-Baralt Luce
Published: October 2022

Estamos en medio de una noche oscura de 1593. En medio de una medianoche oscura, pues tenemos documentados los hechos históricos. El cuerpo de san Juan de la Cruz es trasladado sigilosamente por despoblados  desde Úbeda, donde había muerto, hasta Segovia. El alguacil de Corte, don Juan de Medina, custodia los restos junto a los guardias que lo conducen en una litera. Al llegar a Martos se les aparece un hombre que les grita a grandes voces: "¿Dónde lleváis ese difunto, bellacos? Dejá el cuerpo del fraile que lleváis..." (Pasquau 1960: 2). La aparición "causó gran susto en el alguacil y sus compañeros, que se les espeluzaron los cabellos" (Fernández Navarrete 1819: 78-79). Más adelante en el camino aparece otro hombre, que vuelve a pedir cuenta al séquito de lo que llevaban e insiste en interrogarlos. En medio de tantos encuentros tensos, el conductor del féretro advierte que unas luces brillantes rodeaban la caja pequeña que contenía el cuerpo del santo.
Ecoteologia da Libertação em Diálogo com a Poesia em algumas Canções que abordam a temática
Authors: Maria de Oliveira Márcia , Sbardelotti Emerson
Published: October 2022

O presente artigo foi inspirado pela comemoração de 25 anos da publicação de dois livros importantes: 1. Ecologia: Grito da Terra, Grito dos Pobres – Dignidade e direitos da Mãe Terra, de Leonardo Boff; 2. Teologia e Literatura: Reflexão teológica a partir da Antropologia contida nos romances de Jorge Amado, de Antonio Manzatto. Nestas obras encontramos o diálogo frutífero entre Teologia da Libertação e Ecologia, e o diálogo salutar entre Teologia da Libertação e Literatura. O objetivo do artigo é mostrar, a partir destes diálogos, as canções que abordam a questão ecológica, que ressurgem e, ou germinam, com um novo ar primaveril, amazônico, samaritano, numa Igreja que procura estar em saída, toda ministerial e sinodal, no seguimento a Jesus de Nazaré. São três canções: de artistas da Música Popular Brasileira e das Músicas da Caminhada que, ajudam-nos a refletir o papel da poesia em diálogo com a ecoteologia, e como tais canções fazem perceber as raízes éticas e espirituais dos problemas ambientais, convidando-nos a uma mudança de comportamento, a uma mudança profunda enquanto seres humanos. A metodologia utilizada foi a pesquisa bibliográfica e vídeos do You Tube com as canções
Transposiciones del acontecimiento
Authors: Ramos Hendez Juan Carlos
Published: October 2022

La presente comunicación presenta una lectura comparatista desde la teoría y crítica literaria, articulada con el concepto de desarrollado por Erich Auerbach, que funciona en el sentido tipológico, en la figura transposición que planteamos entre dos mariofanías: el acontecimiento de Fátima (1917) como figura de las apariciones a tres videntes en Bogotá (1989). El caso se constituye a partir de un relato oral que reescribe el mensaje de Fátima en la experiencia vital de los videntes colombianos. Esta relación pone en tensión la concepción del tiempo y de la historia, la cual pensaremos desde la hermenéutica benjaminiana, como una constelación. Daremos cuenta de las problemáticas que implican pensar el acontecimiento epifánico —con fragmentos del material textual de las apariciones—, operados con categorías como la de tiempo mesiánico desarrollada por Giorgio Agamben, la relación entre promesa y consumación desde el hos me paulino (constelación entre pasado y futuro), la irrupción del acontecimiento (metáfora plasmática) en el paradigma religioso (mesianismo) y el secular (la revuelta y la revolución), y la dimensión política que subsiste directamente en el contenido del mensaje de Fátima y las diferentes hermenéuticas del mundo (cristianismo, capitalismo, marxismo) regidas por la experiencia vital de la modernidad: el devenir revolucionario.

Toponymy in brazilian sign language
Authors: Carmo Felipe dos Santos do , Sousa Alexandre Melo de
Published: October 2022

Toponymy is the field of Linguistics dedicated to the study of proper names of places (toponyms). This is one of the areas of Onomastics, which studies proper names in general. This study analyzes toponymic signs in Libras that name urban spaces (squares, parks, and leisure spaces) in the City of Rio Branco, State of Acre, Brazil. It taps into the morphological structure and the semantic-motivational aspects of 12 toponymic signs. The study methodology is built on Author 2 (2018, 2019b, 2021a), who drew on Dick’s (1990, 1992) theoretical and methodological framework. The results pointed to a hybrid compound formation in 41.6% of the signs and material culture references as motivation for 42% of them (ergotoponyms). The results are part of the Project “Toponymy in Libras”, developed at Universidade Federal do Acre.
Sentir e inteligir na construção de um caminho místico
Authors: Arnoso Santos Rodrigo José , Gomes Rogério
Published: October 2022

O intuito deste artigo é estabelecer um diálogo entre Xavier Zubiri e Anselm Grün. Parte-se de dois conceitos importantes da reflexão zubiriana, sentir e inteligir, como bases antropológicas fundamentais para construir um caminho místico. Zubiri tem a oferecer uma compreensão acerca do sentir e do inteligir, enquanto Grün parte da cotidianidade, das questões fundamentais e da simplicidade de linguagem para ajudar os interlocutores a fazerem a experiência e reflexão místicas. Os dois autores oferecem elementos substanciosos para quem deseja adentrar no campo da teologia espiritual, sobretudo, da mística.
