Authors: Maldonado Carlos Eduardo
Published: December 2020

Este artículo presenta la historia del seminario más antiguo  en América Latina sobre complejidad; específicamente, sobre ciencias de la complejidad. Como metodología se basa en la autoetnografía. Se presenta su historia, sus contenidos, dinámicas y futuro previsible. Se estudiaron experiencias semejantes de complejidad en América Latina y no se encontró ni continuidad o antigüedad, ni productos evidentes de un seminario análogo. La conclusión a la que se llega es que un seminario de investigación vale por dos características: su permanencia en el tiempo y los productos que presenta. En investigación existen dos clases de productos: tangibles e intangibles. La bibliografía al final da cuenta de productos tangibles; es decir, libros, capítulos de libro, artículos. Un producto intangible consiste en la producción de clases o actividades semejantes.

Published: December 2020

O consumo dos recursos naturais trouxe à tona questionamentos sobre o que pode ser feito para evitar prejuízos cada vez maiores à natureza. Sendo assim, as Unidades de Conservação (UCs) passam a exercer papel primordial no processo de proteção ambiental. Soma-se a isso o plano de manejo, instrumento que estabelece o zoneamento da UC e as normas que devem presidir o uso da área. Nesse contexto, este trabalho objetivou propor o zoneamento ambiental da REBIO das Araucárias a partir do processamento de atributos topográficos e das suas correlações com o uso do solo. Para tanto, foram gerados diversos atributos topográficos derivados do Modelo Digital do Terreno (MDT). Como resultados, verificou-se que a utilização dos atributos topográficos possibilitou o entendimento das informações pedológicas e de limitação de uso (susceptibilidade ambiental). Logo, para o zoneamento, realizou-se tabulação cruzada entre a Limitação de Uso e o Uso do Solo, sendo delineadas as Zonas de Manejo da unidade. Environmental zoning proposal for the Araucária Biological Reserve based on topographic attributes A B S T R A C TThe consumption of natural resources has raised questions about what can be done to avoid increasing damage to nature. Thus, Conservation Units (PAs) play a major role in the process of environmental protection. Add to this the management plan, an instrument that establishes the zoning of the CU and the norms that should govern the use of the area. In this context, this work aimed to propose the environmental zoning of REBIO das Araucárias from the processing of topographic attributes and their correlations with land use. For this, several topographic attributes derived from the Digital Terrain Model (DTM) were generated. As results, it was verified that the use of the topographic attributes made possible the understanding of the pedological information and of limitation of use (environmental susceptibility). Therefore, for the zoning, a cross-tabulation was performed between the Use Limitation and the Land Use, and the Management Areas of the unit were delineated.Keywords: Geotechnology; Topographic Attributes; Protected Áreas.

Sustentabilidad ambiental urbana. Una revisión a la situación ambiental en Bogotá (1990-2018) desde el materialismo histórico geográfico
Authors:   Universitaria Agustiniana, Duquino Rojas Luis Gabriel
Published: December 2020

Esta investigación aborda la problemática ambiental de la ciudad de Bogotá, entre los años 1990 y 2018, y está planteada desde la revisión de las relaciones existentes entre los procesos de evolución urbana (construcción de espacialidad de la ciudad) y degradación ambiental urbana (sobreexplotación de los recursos naturales y del espacio geográfico original). Estos fenómenos se han dado en el marco de la evolución de los procesos de imposición de estructuras ideológicas de dominación del sistema capitalista (su fase financiera y de servicios), y en los modos de vida y acción de la sociedad, desde lo más pragmático hasta lo simbólico y lo cultural. La perspectiva de estudio se apoya en el materialismo histórico-geográfico planteado en la obra de David Harvey y el planteamiento teórico conceptual asociado a la sustentabilidad ambiental, propio de los estudios de Enrique Leff. El capítulo da cuenta de un estudio geohistórico a la luz de las relaciones estructurales sociedad-naturaleza, desde una aproximación donde la crisis ambiental es el reflejo de una crisis civilizatoria; una encrucijada ambiental que es multidimensional y que se asienta en esferas vitales de la civilización contemporánea como la economía y la urbanización planetaria.

Authors:   Universitaria Agustiniana, Hernández Fox Leonor Arlen
Published: December 2020

La presente obra tuvo como objeto de investigación las normas y las transgresiones ocurridas en la vida familiar, en especial de las mujeres, en Cartagena de Indias y La Habana, las principales ciudades puertos del Caribe junto con Veracruz y Portobelo, entre 1759 y 1808. La consulta de una amplia variedad de fuentes localizadas, entre otras instituciones, en el Archivo General de Indias en España, el Archivo General de la Nación en Colombia y el Archivo Nacional de Cuba, así como la aplicación del método de la crítica histórica, permitieron demostrar que la legislación y los discursos producidos por el despotismo ilustrado con el fin de controlar la vida familiar reforzaron la normatividad patriarcal, destinada a consolidar la subordinación femenina ante la autoridad de los varones. Esto generó múltiples situaciones conflictivas y transgresoras, en las que las mujeres asumieron un rol protagónico como una alternativa válida para la defensa de sus derechos.
Regional Flood Frequency Analysis using Dimensionless Index Flood Method
Authors: Ibeje Andy Obinna , Ekwueme Ben N.
Published: December 2020

Hydrologic designs require accurate estimation of quartiles of extreme floods. But in many developing regions, records of flood data are seldom available. A model framework using the dimensionless index flood for the transfer of Flood Frequency Curve (FFC) among stream gauging sites in a hydrologically homogeneous region is proposed.  Key elements of the model framework include: (1) confirmation of the homogeneity of the region; (2) estimation of index flood-basin area relation; (3) derivation of the regional flood frequency curve (RFFC) and deduction of FFC of an ungauged catchment as a product of index flood and dimensionless RFFC. As an application, 1983 to 2004 annual extreme flood from six selected gauging sites located in Anambra-Imo River basin of southeast Nigeria, were used to demonstrate that the developed index flood model: , overestimated flood quartiles in an ungauged site of the basin.  It is recommended that, for wider application, the model results can be improved by the availability and use of over 100 years length of flood data spatially distributed at critical locations of the watershed. Doi: 10.28991/cej-2020-03091627 Full Text: PDF

Nowadays so-called traceability systems that provide fixing of history, application, and location of a product during its life cycle are formed in many spheres. Large scale and territorial distribution of petroleum supply systems require some electronical sensor fields and the same for data receiving, processing, visualization, and situation identification. Example of this kind of systems is so called guaranteed petroleum product logistics automation control system that provides petroleum product preserve during tank truck deliverance from oil terminals to gas stations. In the sphere of petroleum supply also some technology development and successful in-Russia and abroad application experience tell us about possibility of express-determination of petroleum product quality characteristics by means of spectroscopy. This method provides increase of test speed of all of the samples possible or necessary and even take and investigate sample «in-flow» (physically in pipelines, logically by means of mobile laboratories, etc). Quality parameter magnitudes may be used by automation systems of various levels to increase control efficiency. The article deals with determination, analysis and synthesis of the traceability systems for quality control of petroleum product.
Fuzûlî’nin Rind ü Zâhid’i örneğinde tasavvufta vahdet düşüncesi
Authors: KARAYAZI Nurgül
Published: December 2020

Tasavvufî geleneğin temel konularına şiirlerinde yer veren ve bu geleneğin tedrisinden geçtiği düşünülen XVI. yüzyılın mihver şâiri Fuzûlî’nin Farsça kaleme aldığı mensur Rind ü Zâhid adlı eserinde Muhyiddin İbnü’l-Arabî’den sonra sistemleşen vahdet-i vücûd düşüncesinin izlerini görmekteyiz. Eserde Rind ile Zâhid’i fikrî çerçevede karşılaştıran şâir, tevhid prensibine göre Hakk’a varılan yolun vahdet düşüncesinden geçtiği, bu yolda ikiliğe yer olmadığı ve bunu ancak muvahhidlerin başarabileceği kanaatindedir. Ayrıca, gönlün aklın ötesinde bir kavrayışa sahip olduğu, sırrın görünenin ötesinde görünmeyende bulunduğu hatta bâtının zâhirin içinde saklı olduğu, Rind ile Zâhid arasında münâzara edilen her meselelerin neticesinde varılan bir hakikat olarak karşımıza çıkarılmaktadır. Kâinatta tecellî eden her güzellik ilâhî güzelliğin bir tezâhürüdür. Temâşâ ettiğimiz her şey, bakış açımıza göre kötü gözükebilse de Hakk’ın sanat eseri olması hasebiyle hakîkatte güzeldir. Çünkü Allah her neyi yaratmışsa güzeldir. Muvahhid, her tecellînin bir nakış olup Nakkaş’a işâret ettiği hakikatini idrâk etmelidir. Çalışmamızda sûretten çok sîrete yönelmenin hakîkat yolundaki sâlik için en önemli hedef olduğunu belirten eser, tasavvufî kavram ve unsurlar göz önünde bulundurularak değerlendirilecektir.

Published: December 2020

En este trabajo se caracterizaron polvos de cobre y óxido de zinc embebidos en una matriz de dióxido de silicio. La relación molar de los polvos de ZnO y Cu fue de 2:1. Las propiedades antibacteriales conjuntas del ZnO y del Cu y la naturaleza semiconductora del ZnO favorecen la inhibición de microorganismos por estrés oxidativo y lisis celular; adicionalmente se favorece la transformación de compuestos volátiles indeseables por fotocatálisis. Las partículas de Cu se obtuvieron por reducción química y las nanopartículas de ZnO por la técnica hidrotermal. La espectroscopia infrarroja reveló bandas de absorción a 510 cm-1, 1100 cm-1 correspondientes a los enlaces Zn-O y Si-O, respectivamente. Por difracción de rayos X se observa la presencia de la fase Wurzita del ZnO. Los patrones de difracción del cobre Cu muestran los picos característicos de la estructura cúbica centrada en las caras.

La extracción sólido líquido de fuentes vegetales es una bioseparación ampliamente utilizada para la obtención de sustancias orgánicas de interés en la industria alimentaria, farmacéutica y cosmética. En el presente trabajo se estudió la operación de extracción con el modelo resuelto de Simpson por calculo fraccional de la expresión de difusión anómala de la segunda ley de Fick para estudiar el efecto de la microestructura y la temperatura en el comportamiento de la extracción y el tiempo de extracción. La determinación del tiempo de extracción es de gran importancia para el proceso ya que de no alcanzarse disminuye el rendimiento obtenido de la fuente vegetal y de ser mayor reduce su rentabilidad. Para ello se propuso un método numérico novedoso que define como tiempo de extracción aquel en el que se tiene un cambio marcado en la velocidad de extracción. La simulación se realizó con Matlab y se evaluó los parámetros del modelo que representan el efecto de la microestructura (n) y el efecto de la temperatura (k) de manera individual y combinado en un rango de 80% a 120% de su valor inicial. El ajuste de los datos experimentales al modelo de Simpson presento una R2 de 0.998, mientras la evaluación del parámetro k (temperatura) mostró tener menor consecuencia en el comportamiento y tiempo de extracción que el parámetro n (microestructura) los cuales presentaron tiempos de extracción de 507.8 a 14.5 min. y de 79.3 a 46.6 min. para n y k respectivamente. Los resultados de la simulación fueron congruentes con los observados en biomateriales con estructuras claramente diferentes como las de semillas y frutos procesados a diferentes temperaturas por lo que los métodos numéricos propuestos pueden ser una herramienta útil en esta bioseparación.

Published: December 2020

Além da importância do design como uma das variáveis decisivas da eficácia empresarial, observa-se que este é mais do que somente um processo projetual, uma vez que, algumas empresas adotam a gestão do design como estratégia competitiva e instrumento de construção da imagem corporativa. Neste sentido, este estudo busca identificar as expectativas de docentes de cursos de Design Digital quanto à disciplina de Gestão do Design, promovendo o pensar diferente, ou seja, inovar, porém, sem esquecer a prática. Dentre os resultados se evidenciou que o pensar sobre a prática é a reflexão que deve possibilitar alternativas para enfrentar as situações-problema na promoção da aprendizagem. A reflexão é o conhecimento que tem solidez teórica, transformando a prática e que vai além do mero fazer.

Efectividad del peeling de azelaico en el tratamiento del melasma: reporte de un caso
Authors: Páez Eva , Tobía Stephany , Colmenárez Vivian , Herrera Kathyuska , Vivas Sandra
Published: December 2020

Se trata de una paciente femenina, de 52 años, natural y procedente del estado Carabobo, Venezuela. El melasma es una hipermelanosis adquirida, crónica, de incidencia variable. Se caracteriza por máculas localizadas en las áreas expuestas al sol. Ha sido una patología de difícil manejo por la poca respuesta a los tratamientos, aunque los peelings químicos siguen siendo una herramienta clave. Los peelings a base de ácido azelaico, en concentraciones superiores al 20%, producen una exfoliación química inducida, con precipitación progresiva de proteínas epidérmicas con mínima reacción melanocítica, acción antiproliferativa y citotóxica en los melanocitos, con inhibición de la actividad oxidorreductasa mitocondrial y síntesis de ADN; además, reducen la hiperpigmentación mediante la inducción de descamación y de un efecto inhibitorio sobre la tirosinasa. La dermatoscopia y el análisis tricromático facilitan la caracterización y el seguimiento de la dermatosis. Por ende, el desarrollo de un protocolo que permita la cuantificación, localización y distribución del pigmento, gracias al cálculo de píxeles en cada canal RGB, sería de gran utilidad para establecer un tratamiento adecuado.

La toma de decisiones de gobiernos y sectores de la sociedad, intuiciones y datos en tiempos de pandemia SARS-COVID-19
Authors: Acosta Ortiz Alida María
Published: December 2020

Uno de los cuestionamientos más recurrentes durante la pandemia ha girado alrededor de la toma de decisiones y el tipo de evidencia que las respalda. Comparada con otras crisis como la económica del 2008, que principalmente afectó al sector financiero; o el escenario de malas decisiones durante la epidemia de la gripe aviar en la década de los setenta (1), la pandemia por COVID-19 ha afectado todo el sistema socioeconómico y generando incertidumbre ha aumentado la percepción de riesgo. Esto ha hecho que se requieran tiempos de respuesta más cortos, así como una reflexión del sistema de valores de las sociedades en el proceso de toma de decisiones. En este contexto, las evidencias provienen de diferentes sectores y de diferentes ramas del conocimiento. La pregunta que razonablemente surge entonces es: ¿A quién escuchar?

La rapidez con que se deben tomar las decisiones en tiempos de pandemia requiere un ajuste al modelo de toma de decisiones basado en evidencia que demanda información con alta credibilidad y libre de sesgos. Por ejemplo, el resultado de investigación científica de calidad. Supone además que la información disponible sea el resultado de un exhaustivo análisis y una evaluación metódica, además de accesible y fácil de entender.

En la actual coyuntura estos estrictos requerimientos son casi imposibles de atender. Se ha pasado de utilizar exclusivamente información de alta credibilidad, a aceptar información razonablemente creíble; de priorizar la información mediante una evaluación sistemática, se ha pasado a hacer una valoración desde la subjetividad del juicio profesional y la experiencia de quienes evalúan la información disponible.

The sediment-hosted polymetallic (Pb, Zn, Ag, Au-Cu) mineralization of the Vale do Ribeira Mineral District has been known since the beginning of the 20th century, but exploration was interrupted just before the turn of the century. The Vale do Ribeira Mineral District is part of the Southern Ribeira Belt, developed during the Brasiliano-Pan African orogeny. Polymetallic mineralization is mainly hosted in metalimestones of the Lajeado Group, a typical platform carbonate sequence of a passive margin, which has been deformed during the Gondwana assembly. The region has a gap of research since the mines were closed, which justifies new projects on their mineral economic potential. Fieldwork, petrographic and geochemical analyses were developed in five currently inactive mines (Panelas, Barrinha, Rocha, Lajeado, and Furnas) and their surroundings, along with the description of a drill core executed in the 1980s. The main type of ore consists of polymetallic fault-fill veins of massive sulfide, which are composed essentially by argentiferous galena, sphalerite, pyrrhotite, arsenopyrite, and chalcopyrite. The highest ore grades were obtained from samples in the Panelas Mine, with contents of up to 35% lead, 5% zinc, > 1% copper and 564 ppm silver, as well as 23% iron. New ore occurrences were described in a secondary gallery of the Barrinha Mine, whose gold grades reached up to 5,630 ppb. The main controls of the mineralization are lithological - since the ore occurs exclusively in carbonate rocks, irrespective of the geological unit - and structural, related to NE high-angle strike-slip fault zones, including evidence of fault-valve behavior. Fault zones as the main control of the polymetallic veins is an innovative interpretation, increasing the perspectives for mineral exploration in the area. Although they are small deposits, the presented data indicate that the region has potential for new discoveries and that the mined deposits are probably not exhausted.

We present a methodological proposal for the systematic mapping of superficial formations applicable on a national scale. The importance of such a proposition stems from the fact that a large part of the Brazilian territory is located in a humid or semi-humid tropical zone, where deeply weathered and sometimes tens of meters thick lateritized regolith mantles develop. The methodological approach consists of a geological-geomorphological-pedological compartmentalization of the terrains, together with elements of morphostratigraphic analysis and of the intrinsic properties of saprolites and soils. This approach, structured in a GIS environment, was applied in two different areas in Brazil: The Federal District and the São Luis island in the state of Maranhão, where the complex geodiversity of the regolith landscape stands out in both areas. The results highlight the diversity of horizons in the regolith profile, in addition to its anisotropy. The recognition of the complexity of these superficial formations is, therefore, of great importance for a more detailed analysis of various themes, such as for civil works; susceptibility to erosion and mass movements; potential for aquifer recharge; and mineral potential. Finally, the importance of the study of superficial formations is emphasized for the improvement of geological mapping and for the multi-thematic analysis of the physical environment applied to land management.

The provision of jumping tasks (JT) is an effort to improve students' problem-solving abilities. Descriptive qualitative research was conducted to describe and analyze students' ability to solve mathematical problems, both in the field-dependent cognitive style (FD) and independent field (FI). JT is a high-level question, C4-C6, in Bloom's taxonomy on the Three Variable Linear Equation System topic. The subjects in this study were students of class X MIPA 1 of SMA Negeri 4 Jember with 30 students consisting of 5 FD students and 25 FI students. The data collection method uses tests (JT questions) and interviews. The results showed the differences in FD and FI subjects' ability in the stages of carrying out the plan of completion and re-checking, i.e., the FI subject had better solving ability than the FD subject in the stage of planning the completion and re-checking. In contrast, at the other Polya stages, there were no differences.
Bahasa Matematis Masyarakat Yogyakarta: Suatu Kajian Etnografi
Authors: Prahmana Rully Charitas Indra
Published: December 2020

Yogyakarta has a nickname as the City of Culture. Yogyakarta has several cultures that are closely related to the context of learning mathematics. However, not many educators in Yogyakarta see this culture as a context that can be a starting point in learning mathematics. Thus, this study aims to explore the culture of Yogyakarta's people that can be used as a context in learning mathematics. This study uses ethnographic studies sourced from literature studies, field observations, and interviews with informants who understand the ancient Javanese language well to clarify and / or provide more understanding of the results of the literature review collected. The results showed some mathematical languages used by the Yogyakarta people in Javanese that could be used as starting points in learning mathematics. This mathematical language includes the mention of numbers, area, angle, volume, indefinite units, and determination of time units.

The Impact of the Agency Role-Based Model on Decision Making in Real Estate Development Projects
Authors: Zhai Ge
Published: December 2020

The professionalism of real estate development makes the decision-making environment of development relatively complicated. Building the decision model can help investors make reasonable decisions in real estate development. This paper analyses the construction project of Berlin Brandenburg Airport by using the agency role-based model of real estate development proposed by Adams & Tiesdell. The research found that the existing research is looking for different objective factors from real estate development cases, without analysing the influence of actors involved in the development process on the entire real estate development decision. In the process of real estate development, not only the changes in the market environment should be considered, but also the influence of different roles on decision-making in the development process. The conclusion of this paper provides a useful supplement to the real estate development model and proposes specific improvement measures.
The evolving burden of asthma and contemporary advances in management: Implications for clinical practice in Southern Africa
Authors: Andrew Kiboneka
Published: December 2020

Asthma is a rising significant global public health burden especially in the developing countries. The annual prevalence of severe asthma episodes is estimated from 1% to 21% for adults and over 20% for children aged 6–7 years. The prevalence of asthma varies widely around the world, ranging from 0.2% to 21.0% in adults and from 2.8% to 37.6% in 6- to 7-year-old children. The International Study of Asthma and Allergies in Children (ISAAC) reports a significant increase in the global prevalence of asthmatic episodes among children. t was estimated that more than 339 million people had Asthma globally in 2016. It is a common disease among children. The common disease asthma is probably not a single disease, but rather a complex of multiple, separate syndromes that overlap. Most asthma-related deaths occur in low- and lower-middle income countries. According to the World Health Organization (WHO) estimates, there were 417,918 deaths due to asthma at the global level and 24.8 million DALYS attributable to Asthma in in 2016. The WHO has estimated that the economic costs associated with asthma have exceeded those of TB and HIV/AIDS combined, and the Global Initiative for Asthma Program forecasted the number of asthma patients to grow globally to greater than 400 million by the year 2025. Since its first description by Hippocrates, asthma remains a treatable yet incurable disease. It is now clear that asthma is a complex syndrome with variable severity, natural history and response to treatment In Namibia a prevalence of Asthma of 11.2 % has been reported in adult populations. The increase in asthmatic episodes, morbidity and mortality among populations in Africa, Latin America and parts of Asia is a rising public health concern. The development of novel asthma phenotyping & endo typing plus better classification of patients using machine learning and big data have markedly improved asthma treatment outcomes in both children and Adults. Several research groups have developed cluster analyses of phenotypes in severe asthma. These clusters support the importance of disease heterogeneity in asthma and suggest differences in pathophysiologic mechanisms that define these clusters. Precision medicine is "an emerging approach for disease treatment and prevention that takes into account individual variability in genes, environment, and lifestyle for each person.
