Authors: MOUSAVIFARD Zahra Al-Sadat , KHAJEHNASIRI Farahnaz
Published: August 2021

introduction: Coronavirus (COVID-19) has recently emerged as a global threat. Workers' knowledge, attitudes, and practices about this new infectious disease are crucial to its prevention and control. This study was conducted to the status of knowledge, attitude, and practice was determined according to the COVID-19 prevention guidelines and the factors affecting it in the service workers of Tehran Metro Line 1 in the fall of 2020
Methods: This cross-sectional (descriptive-analytical) study was performed on 113 service-cleaning workers of Tehran Metro Line 1 with a mean and standard deviation of the age of 35.38+_5.43 in the fall of 2020. Data collection tools included a demographic questionnaire and a 32-item questionnaire to assess the status of knowledge, attitude, and practice to the COVID-19 prevention guidelines (with optimal validity and reliability). Answers were measured with pros, cons, no comments. Findings were presented by descriptive and analytical statistics and data analysis was performed by analytical tests of SPSS software version 25 with a significance level of p <0.05.
Results: The results of the study showed that in the field of knowledge, attitude, and practice with 74.9%, 83.2%, and 99.2% of the participants were at a good level, respectively. There was a significant relationship between age and attitude of participants in the study (p <0.05) so that the The attitudes of 30-34 years old were significantly different from the attitudes of other age groups There was also a significant positive relationship between education and performance of participants (p <0.05), people with a bachelor's degree had better performance. The relative frequency of non-COVID-19 infection in the study participants from the beginning of the disease until now (autumn 1399) was 68.1%.
Conclusion: In order to correct misconceptions and promote awareness and attitudes of the population of the study about COVID-19 , it is recommended that education and information be provided through the media. The good level of knowledge, attitude, and practice of the service workers - cleaning the subway towards the Covid-19 virus, had caused the incidence of coronary heart disease among them to be almost 30%. In this regard, the distribution of appropriate personal protective equipment, daily disinfection of subway stations can be effective factors in reducing the incidence of workers.
Internet of Things Based Cutting Tool Status Monitoring in a Computer Numerical Control Milling Machine
Authors: Natarajan K. K. , Gokulachandran J.
Published: August 2021

The Internet of Things (IoT) in the manufacturing industry shares machine data in real time. The majority of industrial data can be gathered and processed from machines and other remote IoT devices in a production system through data streaming. As sensors become smaller and more affordable, the Internet of things will attract more attention. It is possible to employ a wide range of sensors for monitoring, and with efficient open-source software, the status of the operation can be evaluated effectively. Our work aims at providing instructions for sending data (cutting tool status time) from Particle Photon devices connected to CNC milling machines to open-source software called ThingSpeak. This task is accomplished by integrating the Particle Photon device with the infrared sensor to the CNC milling machine. Three axis CNC vertical milling machine is used to manufacture the sample component. The status of the cutting tool, in this case the cutting time for each machining feature is monitored. Using infrared technology, the sensor detects whether the cutting tool is present. Particle photons measure machining time and communicate it to ThingSpeak. The ThingSpeak library will interpret the cloud information and displays it. With ThingSpeak software, we define the fields for various cutting tools and track every tool in real time. The time recorded using ThingSpeak software is found to be near to the time, which is monitored manually by the user. A major step in computer assisted process planning in manufacturing is monitoring the machining time for each cutting tool and it is successfully implemented in this research work.

La docencia durante la pandemia del COVID19 se ha visto en la necesidad de migrar a los recursos digitales de educación a distancia. Diseño Industrial de la Universidad Rafael Landívar asumió el reto, mismo que se vuelve aún más complejo con asignaturas como la de práctica profesional. La relación con una empresa o cliente real tuvo que desarrollarse combinando plataformas de video llamadas, correos electrónicos y aplicaciones de mensajes de texto. A pesar de las dificultades de metodología, conexión e interacción humana, la gestión del diseño logró sus objetivos y las contrapartes externas fueron receptoras del diseño innovador de los estudiantes landivarianos.
La rueda de la maravilla y el deseo inalcanzable del Sueño Americano
Authors: Marzorati Zulema , Pombo Mercedes
Published: August 2021

El Sueño Americano es un concepto central en el discurso de la identidad del pueblo estadounidense, desde su constitución como país hasta la actualidad. En términos generales, consiste en trabajar arduamente y progresar hasta lograr el éxito, pudiendo ser alcanzado por todos sus habitantes. Para Chomsky (2017) estamos asistiendo al réquiem de ese sueño, supuestamente igualitario y justo, debido a la creciente degradación democrática y concentración de la riqueza, que otorga mayor poder político a los ricos. El objetivo de nuestro trabajo es abordar esta temática desde las representaciones de La rueda de la maravilla (Woody Allen, 2017) un film que combina drama y tragedia con una puesta en escena en la que lo cinematográfico se une con lo teatral. Ambientada durante la década del ´50 -en que el crecimiento económico y el consumismo parecían asegurar esa movilidad social para todos los ciudadanos- y situada en Coney Island, centro turístico situado al sur de Brooklyn, símbolo de un esplendor ya decadente en esos años. La historia se centra en una pareja que trabaja en el parque de diversiones, Humpty (James Beluschi) manejando el carrusel, y Ginny ( Kate Winslet ) mesera en un restaurante de almejas. La acción es narrada por el guardavida de la playa, Mickey (Justin Timberlake) que mantiene una relación amorosa con Ginny, hasta que se enamora de la hija de Humpty, Caroline (Juno Temple) quien viene a Coney Island huyendo de la mafia. A través de estos personajes insatisfechos emocionalmente, el texto fílmico condensa a aquellos norteamericanos que han quedado fuera del sueño americano, dejando en claro que se trata de un mito inspirador más que de una realidad.
Crossover metodológico: investigación doctoral en Diseño con instrumentos de la Historia del Arte
Authors: Isidoro Alberto Martín
Published: August 2021

Este escrito busca mostrar la viabilidad que puede alcanzar la investigación doctoral en el ámbito del diseño, si va al encuentro de los métodos de la historia del arte para el análisis tanto de las imágenes como de los objetos visuales de diseño. La historia del arte asumió una actitud epistemológica similar a partir de la década de los 70, asociado a un décloisonnement disciplinario, potenciando sus instrumentos de análisis y considerando novedosas perspectivas temáticas. Lo que lo hace propicio en el campo del diseño es la cercanía disciplinaria que comparten el diseño y la historia del arte. No obstante, hay que advertir que cada disciplina tiene sus propios intereses, enfoques, normas e historia, los cuales modelan su aspecto. Por ello, resulta imprescindible en la transposición metódica, hacer una adaptación a los intereses disciplinarios.

Fanificación y conectividad en las sociedades hipermediatizadas
Authors: Álvarez Gandolfi Federico
Published: August 2021

Este artículo examina las transformaciones de las mediatizaciones y de las condiciones de circulación del sentido en el marco de las plataformas digitales con base en Internet. Para eso se pone la atención en un caso de estudio particular: el de la fanificación que atraviesa la vinculación entre obras audiovisuales, interacciones, producciones discursivas y prácticas en YouTube relacionadas con el consumo de objetos de la cultura de masas japonesa. El objetivo de este trabajo es poner en diálogo las reflexiones sobre tales cambios asociados a la expansión de los medios conectivos y de las lógicas algorítimicas de la dataficación social, con especial énfasis en los interrogantes generados por los estudios sobre fans –campo de constitución incipiente en el ámbito de la academia latinoamericana–. En el contexto de las sociedades contemporáneas hipermediatizadas, se propone revisar la extrapolación de ciertos postulados en torno de la “democracia” y “descentralización” de las redes sociales para el análisis de los usos que hacen de YouTube los fans de bienes culturales japoneses, usualmente conceptualizados en términos de prosumidores. Así se contrastan las oportunidades y limitaciones de la arquitectura de dicha plataforma para la participación, sus apropiaciones y las dinámicas colectivas específicas en torno de uno de los YouTubers o creadores de contenido más populares entre los mencionados fans.

Evaluation de la contribution de l’irrigation à la croissance économique et agricole : cas du Maroc
Authors: Mengoub Fatima Ezzahra , Lejars Caroline , Doukkali Mohammed Rachid
Published: August 2021

Situé dans une zone géographique où les ressources hydriques sont limitées, le Maroc a multiplié les efforts pour gérer ses ressources en eau. Ces efforts se sont concrétisés à travers l’amélioration continue du cadre législatif régissant le secteur de l’eau et s’adaptant aux nouvelles contraintes qu’elles soient climatiques, technologiques et/ou économiques. Dans ce sens, ce travail vise l’évaluation de l’impact de ces interventions publiques sur la croissance agricole et économique observées. La démarche méthodologique adoptée se base sur la méthode de comptabilité de croissance ou « Growth Accounting », développée par Solow en 1957. Elle permet de décomposer la croissance en contribution des facteurs et celle de la productivité. Les résultats de cette étude confirment le rôle primordial que joue l’agriculture en tant que moteur de croissance de l’économie marocaine. Ils montrent également que la contribution de l’eau à la croissance de la valeur ajoutée agricole est de l’ordre de 2% et qu’elle demeure tributaire des conditions climatiques, qui à leur tour changent sous l’effet du réchauffement climatique.

Located in a geographical area with limited water resources, Morocco has multiplied its efforts to manage its water resources. These efforts have been materialized through the continuous improvement of the legislative framework governing the water sector and adapting to the new constraints whether they are climatic, technological and/or economic. In this sense, this work aims at evaluating the impact of these public interventions on the observed agricultural and economic growth. The methodological approach adopted is based on the growth accounting method developed by Solow in 1957. It allows for the decomposition of growth into factor contributions and productivity contributions. The results of this study confirm the primary role played by agriculture as an engine of growth in the Moroccan economy. They also show that the contribution of water to the growth of agricultural value added is around 2% and that it remains dependent on climatic conditions which are changing under global warming.

METERING PIN DIAMETER OPTIMIZATION OF AN AIRCRAFT LANDING GEAR SHOCK ABSORBER
Authors: DİNÇ Ali
Published: August 2021

One of the most important components of an aircraft is the landing gear. In today`s modern landing gears, mostly oleo-pneumatic shock struts are used. Analytically, landing gear can be modeled as a mass-spring-damper system. The model used in the study included landing gear components such as the oleo-pneumatic shock strut, tire and wheel. Furthermore, a tapered metering pin was added to model in order to control the area of the orifice by which hydraulic oil flows during the act of landing impact force. Landing gear design usually aims to minimize two elements which are vertical acceleration and displacement of aircraft mass. The impact force during landing is indicated by vertical acceleration. Displacement of shock absorber should be minimum to decrease the size, weight and space needed for the landing gear system. An optimization problem was defined to minimize those two parameters within the range of given inputs. For this purpose, a composite objective function was created to include and optimize the two output parameters simultaneously with equal weight. Among many inputs, metering pin hub and tip external diameters were selected as variables for the optimization and other inputs were kept constant. For the optimization study, genetic algorithm method was coupled with the Matlab/Simulink model of the landing gear model. After some iterations, solution was converged to determine the two diameters of the metering pin where the vertical acceleration and displacement of aircraft mass are minimized as an objective. At the end of optimization process, vertical acceleration of aircraft mass was reduced from 2.433 g to 1.7828 g (-36.47%) within the given constraint of 2 g maximum. Displacement of aircraft mass X1 was increased from 0.2982 m to 0.3682 m (+23.47%) which is in an acceptable limit of 0.4 m.
An Interview with Nobel Laureate David Baltimore, PhD
Authors: Lederman Michael M. , Greenspan Neil
Published: August 2021

In an online interview, Nobel Laureate David Baltimore, Ph.D., reflected on his contributions to biomedical science that have had a major influence on the fields of molecular biology, virology, cancer, and immunology. Dr. Baltimore is President Emeritus and Distinguished Professor of Biology at the California Institute of Technology. Among other notable works, he discovered the critical nuclear transcription factor NF Kappa B and the Rag1 and Rag2 proteins that rearrange adaptive immune cell receptors.

His career path, he says, evolved naturally, as math and science came easily to him. As a high school student, he participated in a summer program at the Jackson Lab in Bar Harbor, Maine, where he says he came away feeling that experimental biology was exciting and rewarding.

“That's where I discovered that the frontiers of science, were not so distant; that I could actually make a discovery that nobody else in the world knew about,” he says. 

And that he did. Independently, he and Howard Temin discovered the viral enzyme reverse transcriptase revising the canon of cellular information transfer. They published back-to-back papers in Nature demonstrating that this enzyme in virus particles could transcribe RNA to DNA. Both received a Nobel Prize for this work.

In reflecting on his early experience evaluating how to work with recombinant DNA and how we should scientifically and safely approach gain of function research, he says, “We have to be very honest with ourselves about what might hold danger, and we have to control our instinct … to do anything we can to generate progress and understanding of life. …At the same time, we don’t want to hold back progress, and so there is a balancing.”

Dr. Baltimore also discussed his optimism about vectored immunoprophylaxis as a strategy for prevention of HIV and his doubt that scalable strategies will be able to cure HIV. He also reflected on his philosophy for the training of young scientists and the successful training program that he developed at the Whitehead Institute.

LA RELACIÓN ENTRE ESPIRITUALIDAD Y TEOLOGÍA DESDE LA RELACIÓN ENTRE LO VIVIDO Y LO PENSADO
Authors: Zas Friz Rossano
Published: August 2021

El articulo tiene como objeto estudiar la relación entre espiritualidade (lo vivido) y teologia (lo pensado) desde la metodología desarrollada por un nuevo paradigma para interpretar la tradición cristiana e ignaciana desde el contexto actual de post-cristiandad: el de la vida cristiana ignaciana. Para ello en la primera parte se ofrece una síntesis del mencionado paradigma, centrando la atención en la relación entre moción, emoción y decisión en el proceso de toma de decisiones (decision-making), mientras que en la segunda parte se desarrolla la importancia de la noción de transformación desde la formulación de San Ignacio de Loyola y San Juan de la Cruz. En la tercera y última parte de la investigación se exponen las consecuencias para la teología del planteamiento de las dos partes precedentes: se concluye la conveniencia de asumir la noción de ‘vida cristiana’ para expressar holísticamente la experiencia de la revelación cristiana y plantear la ‘teología experiencial’ como renovación de la teologia espiritual.

O CATECUMENATO NO EVANGELHO DE MARCOS
Authors: Carvalho José Carlos Silva
Published: August 2021

Neste artigo, pretende-se mostrar como o discipulado no evangelho de Marcos surge antes de qualquer ritualidade, o que nos faz regressar aos praenotanda do R.I.C.A. (Ritual de Iniciação Cristã de Adultos) e aos processos catecumenais. Sem apresentar a expressão, Marcos narra o percurso dos discípulos como um procedimento catecumenal, em que o grande catequista é Jesus. Para tal, partindo das personagens deuteragonistas - os discípulos - é possível verificar qual a parte do processo batismal que é relevada pelo evangelista, pois é de um processo que se trata. Os discípulos são envolvidos num catecumenato pelo grande catequista Jesus, percurso que atravessa todo o segundo evangelho canônico. Isso faz do discipulado em Marcos um catecumenato, que da parte de Jesus consiste num processo de familiarização.
PALAVRAS-CHAVE: Catecumenato. Discípulos. Batismo. Processo. Rito.

Authors: Kaur Gagandeep , Maremanda Krishna , Campos Michael , Chand Hitendra Singh , Li Feng , Hirani Nikhil , Haseeb M A , Rahman Irfan
Published: August 2021

Background: Chronic Obstructive Pulmonary Disease (COPD) and Idiopathic Pulmonary Fibrosis (IPF) are chronic, progressive lung ailments which are characterized by distinct pathologies. Early detection biomarkers and disease mechanisms for these debilitating diseases are lacking. Exosomes are small extracellular vesicles attributed to carry proteins, mRNA, miRNA and sncRNA to facilitate cell-to-cell communication under normal and diseased conditions. Exosomal miRNAs have been studied in relation to many diseases. However, there is little to no knowledge regarding the miRNA population of BALF or the lung tissue derived exosomes in COPD and IPF. Here, we determined and compared the miRNA profiles of BALF and lung tissue-derived exosomes from healthy non-smokers, healthy smokers, and patients with COPD and IPF in independent cohorts. Results: Exosome characterization using NanoSight particle tracking and TEM demonstrated that the BALF-derived exosomes were approximately 89.85 nm in size and ~2.95 X 1010 particles/mL. Lung-derived exosomes were ~146.04 nm in size and ~2.38 X 1011 particles/mL. NGS results identified three differentially expressed miRNAs in the BALF, while one in the lung-derived exosomes from COPD patients as compared to healthy non-smokers. Of these, three- and five-fold downregulation of miR-122-5p amongst the lung tissue-derived exosomes from COPD patients as compared to healthy non-smokers and smokers, respectively. Interestingly, there were key 55 differentially expressed miRNAs in the lung tissue-derived exosomes of IPF patients compared to non-smoking controls. Conclusions: Overall, we identified specific miRNAs to develop as biomarkers or targets for pathogenesis of these chronic lung diseases.

Relapses and resistance to therapeutic agents are major barriers for treatment of acute myeloid leukemia (AML) patients. This unfavorable circumstance emphasizes the need for new strategies targeting drug-resistant cells. As IDH mutation is present in the preleukemic stem cells and systematically conserved at relapse, targeting mutant IDH cells would be essential to achieve a long-term remission in the AML subgroup with IDH mutation. Here, using a panel of human AML cell lines and primary AML patient specimens harboring IDH mutation, we showed that the presence of IDH mutation through the production of an oncometabolite (R)-2-HG induces vitamin D receptor related transcriptional programs, priming these AML cells to differentiate with pharmacological doses of ATRA or/and VD. This activation occurs in a CEBP-dependent manner. Accordingly, our findings illuminate potent and cooperative effects of IDH mutation and vitamin D pathway to differentiate in AML, revealing a novel therapeutic approach easily transferable/immediately applicable in clinics for this subgroup of AML patients.
Institutional Investors' Monitoring Roles in State Controlled Firms and Income Smoothing Analysis for Stable Growth and Sustainability: Focusing on China Stock Market
Authors: Xu Meng-Jun , Kim Dong-Il
Published: August 2021

The purpose of this study is to examine the relationship between the institutional investors which can affect financial performance for corporate sustainability on the income smoothing. Therefore, this study focus on the connection between the nature of stock rights and income smoothing in China. For this study, hypotheses were established on the relationship each state-controlled companies, income smoothing, and information equilibrium of individual investors, and empirical analysis was conducted through related variables. The analysis results are summarized in three categories as follows. First, this research finds that state-controlled firms (CONTs) prefer income smoothing activities compared to non-state-controlled firms for the long-term sustainable development of firms using data from 2011 to 2019. Second, this study found out that Institutional investors support the behavior of CONTs to smooth their earnings because this behavior is seen as an attempt by CONTs to convey valuable private information to other investors. Third, we was able to discover that institutional investors' monitoring effect is predominantly driven by pressure-resistant institutional investors. This research complements the lack of empirical research on income smoothing and enable to give a guideline that the type of stock rights is a critical key determinant of participation in income smoothing activities for stable growth and sustainability in the future.

They strive to increase body immunity against various viruses, bacteria, and germs.  One of the plants capable of improving body immunity is noni plant. It is much likely to prevent corona virus. Noni fruit contains substance capable of preventing cancer and antimicrobials. skopoletin dan anthraquinon of noni fruit has anti-septic substance that can kill bacteria and fungi in the body. Alkaloid of morinda citrifolia is also effective to increase immunity and to lower cholesterol. Due to its anti-virus property, noni can also cure fever, pain, and cough. For noni fermented beverage, the analysis of SWOT (Strength, Weakness, Opportunities, Threats) has been made for its potential market. The fermented noni drink is expected to be an alternative herbal drink which is healthy and economic-valued. This product is also expected to inspire an innovative enterpreneurship. By making use of often-discarded-noni fruit into fermented noni beverage, people can employ others as noni fruit collectors, thus employment created. The manufacture of the product includes pre-production stage, fermentation production, packaging, promoting, launching, and to the post-production stage. The fermented noni has its particular blend of fresh and sweet flavors. Consumers may get attracted to buy this rich-nutrient herbal drink. The manufacture of fermented noni drink can empower the people of desa pagerngumbuk. They can start by planting the noni plant. Hence, it is expected to make a new enterpreneuship activity among the society of desa Pagerngumbuk. This can be initiated particularly by the women of PKK.
Photo-transformation of aqueous nitroguanidine and 3-nitro-1,2,4-triazol-5-one : emerging munitions compounds

Two major components of insensitive munition formulations, nitroguanidine (NQ) and 3-nitro-1,2,4-triazol-5-one (NTO), are highly water soluble and therefore likely to photo-transform while in solution in the environment. The ecotoxicities of NQ and NTO solutions are known to increase with UV exposure, but a detailed accounting of aqueous degradation rates, products, and pathways under different exposure wavelengths is currently lacking. We irradiated aqueous solutions of NQ and NTO over a 32-h period at three ultraviolet wavelengths and analyzed their degradation rates and transformation products. NQ was completely degraded by 30 min at 254 nm and by 4 h at 300 nm, but it was only 10% degraded after 32 h at 350 nm. Mass recoveries of NQ and its transformation products were >80% for all three wavelengths. NTO degradation was greatest at 300 nm with 3% remaining after 32 h, followed by 254 nm (7% remaining) and 350 nm (20% remaining). Mass recoveries of NTO and its transformation products were high for the first 8 h but decreased to 22–48% by 32 h. Environmental half-lives of NQ and NTO in pure water were estimated as 4 and 6 days, respectively. We propose photo-degradation pathways for NQ and NTO supported by observed and quantified degradation products and changes in solution pH.

Published: August 2021

In this study, five layers of hexagonal cladding and two elliptical air holes based on photonic crystal fiber are discussed highly for many communication areas by decreasing different types of losses such as effective material loss (EML), scattering loss, and conﬁnement loss in the terahertz (THz) waveguiding. Our suggested fiber (H-PCF) and all simulation results are obtained with the finite element method (FEM) and the perfectly matched layer (PML) boundary conditions based COMSOL Multiphysics software have been used to design in the THz region. After investigating all the graphical results, this optical communication-related H-PCF fiber discloses an extremely low effective material loss (EML) of 0.0184 cm−1, with an effective area of 7.07×10-8 m2 and flow of power in the core region of 88% at 1 terahertz (THz). Here, other simulation parameters such as conﬁnement loss, scattering loss, and V-parameter are also presented with a proper graph. So, we can easily say that the reported H-PCF fiber is strongly appropriate for different types of short and long-distance communication applications in the terahertz (THz) wave pulse region.

Background:The Covid-19 pandemic led to significant changes and disruptions to medical education worldwide. We evaluated medical student perceived views on training, their experiences and changes to teaching methods during the pandemic.MethodsAn online survey of medical students was conducted in the Autumn of 2020. An international network of collaborators facilitated participant recruitment. Students were surveyed on their perceived overall impact of Covid-19 on their training and several exposure variables. Univariate analyses and adjusted multivariable analysis were performed to determine strengths in associations.ResultsA total of 1604 eligible participants from 45 countries took part in this survey and 56.3% (n=860) of these were female. The median age was 21 (Inter Quartile Range:21-23). Nearly half (49.6%, n=796) of medical students were in their clinical years. The majority (n=1356, 84.5%) were residents of a low or middle income country. A total of 1305 (81.4%) participants reported that the Covid-19 pandemic had an overall negative impact on their training. On adjusted analysis, being 21 or younger, females, those reporting a decline in conventional lectures and ward based teaching were more likely to report an overall negative impact on their training (p≤0.001). However, an increase in clinical responsibilities was associated with lower odds of participants reporting a negative impact on training (p<0.001). The participant’s resident nation economy and stage of training were associated with some of the participant training experiences surveyed (p<0.05). ConclusionMedical students reported an overall significant negative impact of the Covid-19 pandemic on their undergraduate training. The efficacy of novel virtual methods of teaching to supplement traditional teaching methods warrants further research.
