The quality of electric power is influenced by harmonic factors that occur due to animbalance in the load on the power system. This load imbalance results in a current at theneutral point. This amount of current can cause equipment damage and loss of electrical power.Therefore, an earthing system is needed to parse the current flowing at the neutral point and asa safety for the electric power system in a building. The objective of this research was to specifythe impact of the grounding resistance value of the neutral point on the current THD on theMDP installed during peak load conditions at the Electrical Engineering Campus of UdayanaUniversity in Jimbaran. This research method uses simulation with Simulink Matlab software todetermine the effect of neutral point grounding resistance on current THD in areas withcalcareous soils. The simulation outputs indicate that the value of the earth resistance affectsthe THDi value in the electrical system. The simulation outcomes represent that when the earthresistance value is 5 , the THD of the R, S, and T phase currents is feasible at 17.55%, 19.42%, and 8.86%. Then when the resistance value is lowered by 0.5, the THD of the R, S, T phasecurrents is feasible 17.20%, 17.35%, and 8.79%. This shows that more slight the earthresistance number, the smaller the current THD value.

According to the decree 1285 (1), regulating the approaches of sustainable construction in Colombia as part of the inclusion of "Environmental Criteria for the Design and Construction of Urban Housing" of the Ministry of Environment and Sustainable Development, the following research work is part of the management of passive measures for the improvement of the thermal condition of housing buildings.
Under this approach, the analysis of envelopes (walls and roofing) is key to enriching the proposals for improving thermal comfort focused on light dry construction systems and their components. In the case of walls, described and expanded in the text "Analysis and Evaluation of thermal performance of the Light Dry Construction System in Residential Buildings” (2), factors that trigger heating inside the spaces due to heat transfer phenomena are detected. In this section we isolate the roof variable that is addressed in the current project, called "Analysis and evaluation of the thermal performance of roofing systems used in dry constructions for Residential buildings located in the city of Santiago de Cali and its area of influence", where different roofing solutions are tested in the field considering this variable as fundamental in the analysis, thermal comparison and evaluation, not including architectural management variables that can be simulated later (openings of gaps in specimens and arrangement of spaces).
At the same time, they considered technical aspects that were successful in the previous study, being that they determined the behavior of the components of the construction system and their location; These mechanisms include ventilated chamber and well-performing thermal insulation such as glass wool and polyester foam

Published: February 2023

La micro-generación eléctrica es una alternativa usada en zonas de difícil acceso y que no están conectadas al sistema eléctrico nacional. Para resolver esta limitación, se utilizan diferentes tecnologías de aprovechamiento de las energías renovables, dentro de las que se destacan las turbinas tipo Pelton, las cuales se distinguen por requerir grandes saltos de agua y pequeños caudales. Para el desarrollo e implementación de esta tecnología de generación eléctrica, existen algunas metodologías de dimensionamiento entre las que se destacan: el uso de curvas paramétricas para el diseño del cangilón, dinámica de fluidos computacional para el diseño general de la turbina y del cangilón, y otras metodologías más tradicionales que utilizan métodos gráficos para el diseño del cangilón; todas éstas con algunas deficiencias que no permiten un desempeño óptimo bajo una condición específica de operación. En este trabajo se comparan tres metodologías tradicionales para el diseño del cangilón de las turbinas tipo Pelton (OLADE, Nechleba y Thake), esto con el fin de seleccionar la más adecuada para una condición especifica. Por lo tanto, se hace un análisis del comportamiento dinámico por medio de un análisis modal, y del comportamiento estático estructural en el software de elementos finitos ANSYS. De los resultados obtenidos, todos los cangilones cumplen con dos de los tres criterios de selección pre-establecidos, se destaca la metodología de Thake al tener los mejores resultados en la relación de resistencia - peso.

Effect of operating parameters and modes in the filtration of acid whey using ultra- and microfiltration ceramic membranes.
Authors: Muvdi Nova Carlos Jesus , Cáceres Roa Sergio Alejandro , Mora García Said
Published: February 2023

Whey is a liquid by-product obtained by cheese elaboration, which is not completely used due to the large quantities produced.  As a result, the whey is poured into rivers and soils and becomes a pollutant agent. The valorization of acid whey using membrane clarification was evaluated, where the effect of temperature and membrane cut-off were studied using acid whey. Permeability was three times higher at 70°C than 50°C (163.2±11.1 y 62.4±9.2 L/m2.h, respectively) for membranes with a cut-off of 0.2 µm. Furthermore, the permeate flux for this cut-off was three, six and ten times higher compared with the cut-off of 300, 150 y 50 kDa at 70°C, respectively. The clarification stage was scaled-up with 0.2 µm membranes, achieving about 22 L of whey filtered for Batch mode until a volume reduction factor (VRF) of 5 with protein retention of 68%. In Fed-Batch mode, the retention of protein was 61%, but the filtration could be carried out for longer, reducing fouling and filtering almost the double of the quantity of whey compared with Batch mode. In all cases, the turbidity of permeates was lower than 12 NTU (reduction >99%), regardless of whey turbidity whose values might be superior to 12,000 NTU.

The reactor was operated for 119 days divided into 5 operational phases which included the start-up and the variation of cell-residence time. In order to determine the biokinetic coefficients for starch removal, the cell-residence time was varied between 20 to 4 days, and the system operation was set hydraulic retention time of 24 hours with a completely mixed reactor setup. The chemical oxygen demand concentration was 1000mg/L in the inflow of the reactor and dissolved oxygen remained above 2mg/L.
In this experimentation time, the parameters such as pH, chemical oxygen demand (in the influent and effluent), dissolved oxygen and Mixed liquor suspended solids were monitored. The calculation of biokinetic constants was done by an approximate method, using the graphical Lineweaver-Burk method. The biokinetic coefficients determined were for Maximum substrate removal rate , Half saturation rate constant or affinity constant (  sludge yield coefficient (Y), and Microbial decay or indigenous respiration rate   .
The results showed that Y, ,  and  (  were in the range of 0,3- 0,7 mgSSV/mgBOD5, 2- 8 Day1 and 40-120 mg/L (COD- BOD5), respectively. Values of the coefficients were within the range of those reported for conventional activated sludge processes.
lectura crítica en el giro digital
Authors: Vargas Franco Alfonso
Published: February 2023

El propósito de este artículo es reflexionar sobre las implicaciones que tiene el giro digital en la política educativa sobre la lectura crítica en Colombia. El origen de la discusión surge de la lectura de cuatro documentos del Ministerio de Educación Nacional en el área de Lengua Castellana, publicados en las dos últimas décadas (1996-2016), que permite por un lado describir cómo construyen el concepto de evaluación de la lectura crítica y, por el otro, explorar algunas de sus implicaciones para la didáctica de la lectura en la educación básica y media. El análisis de los textos permite ver la irrupción del discurso de la evaluación por competencias a lo largo de toda la escolaridad básica y media, y su articulación con el de la educación superior a través de las pruebas Saber 11 y Saber Pro. Sin embargo, los documentos requieren una importante adaptación a la lectura crítica en internet y las redes sociales para incorporar los profundos cambios que plantea la digitalización de la cultura escrita en la formación del lector crítico.
inicialización en la lengua de señas colombiana (LSC): análisis a partir de un corpus espontáneo
Authors: Barreto Alex Giovanny
Published: February 2023

Este estudio presenta el proceso de contacto lingüístico entre la lengua de señas colombiana (LSC) y el español, conocido en la literatura especializada como inicialización. En este estudio se usó una metodología mixta de análisis de corpus e interpretación etnográfica en muestras de uso espontáneo de la LSC. Se propone una clasificación de tres tipos de inicialización: simple, prestada y compuesta. En consultas con los colaboradores sordos de la investigación, se encontró que 26 grafemas del alfabeto español están representados en al menos un caso de inicialización. En el corpus de uso espontáneo el 74 % de los grafemas fueron identificados en señas inicializadas, pero el uso de estas ronda solo el 6 % de la muestra, lo que contrasta con el 15 % que se estima en el ASL. Estos resultados son relevantes teniendo en cuenta el bajo prestigio de la inicialización al interior de algunos sectores de las comunidades sordas colombianas. Los resultados sugieren que el español escrito ha dejado una huella importante en la formación de palabras en la LSC.
principio de arbitrariedad y la motivación sinestésica en la lengua
Authors: Rodríguez Fernando G.
Published: February 2023

El principio saussureano de arbitrariedad del signo lingüístico ha sido relativizado desde la casuística de las motivaciones fonética, morfológica y semántica. En particular, de aquella primera es conveniente distinguir el plano de la onomatopeya propiamente dicha, que rescata cualidades de sonido para utilizarlas en la confección de signos, y el de ciertos otros mecanismos de conservación de cualidades físicas del referente que no parten de la esfera del sonido (motivación sinestésica). En este trabajo, luego de relevar el Curso de lingüística general en los pasajes más directamente vinculados con este problema, se traza un sucinto recorrido por los estudios más importantes que en el siglo XXI han desafiado, desde la rehabilitada motivación sinestésica, la preeminencia y la exclusividad de la arbitrariedad como principio conformador de los signos del lenguaje. Se discute la interpretación que mejor corresponde a los diversos resultados de tales estudios para sugerir, en conclusión, que esta variante de motivación entre el significado y el significante deberá reconocerse más abiertamente en plan de comprender, de la forma más apropiada, todos los aspectos de la lengua en su compleja realidad.
Situación de calle en el norte de México: apuntes para un modelo tridimensional de intervención social
Authors: Romero-Plana Virginia
Published: February 2023

El artículo propone un modelo tridimensional de intervención social para población en situación de calle, a partir de un estudio de caso realizado en Hermosillo, Sonora (México) con varones exmigrantes deportados. Una lectura final de la investigación diagnóstica propuso la conformación de tres constructos reflexivos desde los cuales comprender el sinhogarismo: la trayectoria de vida de los hombres adultos mayores en su rol de exmigrantes, la desconexión socio-familiar tras el proceso migratorio, y la deportación y el desamparo socio-estructural basado en la falta de política social y en la exclusión social. La pobreza extrema es una combinación entre escasez de ingresos, falta de desarrollo humano y exclusión social. De acuerdo a esta definición leída desde la mirada de los Derechos Humanos, el marco teórico sobre el que se sustenta el análisis de los resultados y desde el que se proyecta el modelo de transformación se aborda desde dos ejes: a) la pobreza multidimensional y la integralidad del desarrollo y b) la desigualdad y la justicia social. El modelo de transformación social incorpora a los sujetos en su propio proceso de cambio y a sus entornos desde tres dimensiones: 1) individual, 2) socio-familiar y 3) socio-estructural. Los aspectos básicos abordables en este modelo, y desde los cuales se conforman los objetivos de intervención, son los siguientes: proyectos de vida, salud emocional,  oportunidades laborales,  redes socio-familiares, igualdad de género y conciencia social.

Published: February 2023

Los vínculos parentales de apego son determinantes para el desarrollo socioemocional de los hijos. Su estimulación contribuye a promover prácticas sensibles de cuidado que favorecen en la niñez la creación de habilidades para habitar un contexto. Situado en esta idea, la presente investigación analiza las experiencias de paternidad de hombres militares pertenecientes al Ejército Nacional de Colombia. La metodología utilizada tiene un enfoque histórico hermenéutico, de tipo cualitativo y a través de un diseño narrativo se profundiza en categorías relacionadas con la trayectoria de vida paterna, la relación paterno-filial y la dinámica familiar. La técnica empleada es entrevista biográfica y los participantes diez hombres militares de diferentes edades, lugares y rangos. Como resultados, se evidencia que las experiencias paternas se encuentran marcadas por las vivencias de socialización adquiridas durante su rol como hijo. A nivel laboral, los distanciamientos territoriales ocasionados por su jornada de trabajo, sumado a las situaciones de violencia del país, generan dificultades de tiempo para compartir con sus hijos. Como conclusión, la paternidad militar promueve significados asociados a ser un ejemplo a seguir, proveer económicamente el hogar, formar con disciplina y brindar a su familia un entorno de vida seguro.
The cult of Sarapis in Hellenistic Egypt as a continuation of the policy of "merging peoples"
Authors: Sivkina Nataliya Yurievna , Mozherovtseva Aleksandra Dmitrievna
Published: February 2023

As part of their policy aimed at creating a strong Hellenistic Egypt, the Ptolemies created and maintained the syncretic cult of Sarapis. Ancient sources have preserved several beautiful stories and legends about the appearance of this god and his cult in Egypt. The purpose of this work is to clarify the political role of this cult in Egypt, the peculiarities of its perception by different segments of the population, which ultimately influenced the change in the Ptolemaic policy towards the local population. The main research methods are both general philosophical methods – analysis and synthesis, and special – comparative-historical and comparative-genetic methods.   In the modern world, there are a large number of countries (including Russia) in which different peoples live, having different traditions and beliefs. The study of the Egyptian version of the policy of "merging peoples" and the cult of Sarapis, as one of its components, helps to understand what factors should be avoided in an attempt to smooth out contradictions and create a strong interethnic association, which determines the relevance and novelty of the study. According to the creators, the cult of Sarapis should have been understandable and close to both Greeks and Egyptians. Therefore, the image of God, traditions and rituals included Greek and Egyptian elements, which was supposed to bring the population closer together on the basis of worship of this god and contribute to strengthening the central government. But in reality it turned out that in Egypt itself the cult of Sarapis did not become popular with either the Hellenes or the local population. The policy of uniting different ethnic groups on the basis of the religious factor without carrying out the same policy of rapprochement in other spheres (military, administrative, etc.) was doomed to failure.

Toward Better Analysis of Breast Cancer Diagnosis: Interpretable AI for Breast Cancer Classification
Authors: Prananda Alifia Revan , Frannita Eka Legya
Published: February 2023

Recently, some countries have been distressing with the increasing number of breast cancer cases. Those cases were extremely increased in every year. Practicaly, the increasing number of patients was caused by the manual examination. Recently, some researchers have been done in the development of AI method for solving this problem. However, AI itself still has limitation since it worked in the black-box approach which was difficult to be trusted. Thus, to overcome those problems, we proposed a method that was able to classify breast ultrasound images into two classes (benign and malignant) and able to explain how the prediction was made. Our proposed method consisted of four processes i.e., pre-processing step, development of CNN model, interpretable step and evaluation. In this research work, our proposed method performed into 780 breast ultrasound images divided into three classes (133 normal, 210 malignant, and 437 benign). In the training process, our proposed method obtained training accuracy of 0.9795, training loss of 0.0675. The validation process obtained validation accuracy of 0.8000 and validation loss of 0.5096. While, in the testing process, our proposed method achieved accuracy of 0.7923. In the interpretable process using LIME, the LIME result is covered by doctor visualization. It was indicated that LIME was suitable enough in visualizing the important features of breast cancer severity. Regarding to the results, our proposed method has a potensial to be implemented as an early detection method for classifying malignancy of breast cancer in order to help the doctor in the screening process

Статья посвящена цифровой культуре современной КНР, способах ее проявления, культурной преемственности актуальных феноменов повседневности с лучшими образцами из прошлого. Авторы предлагают подробный обзор контента китайского Интернета. В основе обзора лежат каналы современной китайской культуры (кинематограф, индустрия моды, а также гороскопы), получившие новое прочтение в эпоху цифровой культуры. Авторы приходят к выводу о том, что разработка гармоничной, сбалансированной Интернет-культуры с китайской спецификой становится острейшей повесткой дня для культурно-образовательной политики обновленного Китая. Очевидно, что безудержный рост экономики КНР и уверенное повышение благосостояния и достатка простых китайцев обеспечивает глубокое проникновение Интернет-технологий во все сферы жизни жителей Поднебесной. Сегодня Интернет-культура – это важнейшая часть общей культуры, огромная платформа для продвижения идей и мыслей, новаторский способ заявить о себе миру. К числу проблем китайского Интернета следует отнести избыточную вульгаризацию и чрезмерную развлекательность, необоснованная передача ошибочной информации, что наносит удар по социально-идеологическим основаниям современной КНР. Следовательно, разработка гармоничной, сбалансированной Интернеткультуры с китайской спецификой становится острейшей повесткой дня для культурно-образовательной политики обновленного Китая.

The article is devoted to the digital culture of modern China, the ways of its manifestation, the cultural continuity of the actual phenomena of everyday life with the best examples from the past. The authors offer a detailed overview of the content of the Chinese Internet. The review is based on the channels of modern Chinese culture (cinema, fashion industry, as well as horoscopes), which have received a new reading in the era of digital culture. The authors come to the conclusion that the development of a harmonious, balanced Internet culture with Chinese specifics is becoming the most pressing agenda for the cultural and educational policy of a renewed China. It is obvious that the unrestrained growth of the PRC economy and the steady increase in the well-being and prosperity of ordinary Chinese people ensures the deep penetration of Internet technologies into all spheres of life of the inhabitants of the Celestial Empire. Today, Internet culture is an important part of the general culture, a huge platform for promoting ideas and thoughts, an innovative way to express yourself to the world. The problems of the Chinese Internet include excessive vulgarization and excessive entertainment, unjustified transmission of erroneous information, which strikes at the socio-ideological foundations of modern China. Consequently, the development of a harmonious, balanced Internet culture with Chinese specifics is becoming the most pressing agenda for the cultural and educational policy of a renewed China.

В данном исследовании осуществлено определение особенностей психологической адаптации борцов самбо первого года тренировок. В исследовании приняли участие 60 респондентов из них 30 спортсменов боевого самбо первого года тренировок в возрасте 10-12 лет и 30 подростков, не занимающихся спортивными видами деятельности. Исследование проводилось в два этапа: в начале цикла тренировок по боевому самбо и через год активных тренировок. В качестве методики исследования адаптации нами была выбрана методика социально-психологической адаптации СПА (Роджерс-Даймонд). Были выявлены значимые различия в исследуемых группах в показателях «адаптивность», «дезадаптивность», «непринятие себя», «внешний контроль», «ведомость». Уровень психологической адаптации спортсменов в течении первого года тренировок значительно вырос по сравнению с уровнем психологической адаптации сверстников, не занимающихся спортивной деятельностью. Можно предположить, исходя из результатов, что тренировки по боевому самбо положительно влияют на понижение восприимчивости к психологическому воздействию со стороны посторонних лиц. В дальнейшем автор планирует дополнить исследование данными о исследовании особенностей психологической адаптации спортсменов первого года тренировок других видов спортивной деятельности.

In this study, the features of psychological adaptation of SAMBO wrestlers of the first year of training were determined. The study involved 60 respondents, including 30 combat sambo athletes of the first year of training aged 10-12 years and 30 teenagers who are not engaged in sports activities. The study was conducted in two stages: at the beginning of the combat sambo training cycle and after a year of active training. As a method of adaptation research, we have chosen the method of socio-psychological adaptation of the SPA (Rogers-Diamond). Significant differences were revealed in the studied groups in the indicators "adaptability", "maladaptivity", "self-rejection", "external control", "statement". The level of psychological adaptation of athletes during the first year of training has significantly increased compared to the level of psychological adaptation of peers who are not engaged in sports activities. It can be assumed, based on the results, that combat sambo training has a positive effect on reducing susceptibility to psychological influence from outsiders. In the future, the author plans to supplement the study with data on the study of the features of the psychological adaptation of athletes of the first year of training other sports activities.

Пандемия COVID-19 повлияла на все без исключения сферы общественной жизни. Сфера образования почувствовала на себе, одной из первых, влияние коронавирусной эпидемии и отреагировала на установленные ограничения переводом всей образовательной деятельности в дистанционный режим. Стремительный переход многих образовательных процессов в другой формат вызвал необходимость быстрого приспособления к новым условиям со стороны государственной власти, профильных министерств и непосредственно учреждений образования. Изменения, которые происходят в учреждениях высшего образования, касающиеся методов обучения, самого подхода к преподаванию, формирования компетенций у соискателей образования, организации учебного процесса, что вызвало неоднозначную реакцию у участников образовательного процесса. Такой кризис исполнил роль стимула для инноваций в образовательной среде. Для обеспечения непрерывности обучения и профессиональной подготовки разрабатываются суперсовременные решения для дистанционного обучения и используются различные новаторские подходы, ведь образование – это не просто одно из основных прав человека. Это основополагающее право, от которого напрямую зависит реализация всех остальных прав человека. Образование-это всемирное общее благо, мощнейшая движущая сила прогресса для достижения целей в сфере развития общества и основа равноправного, справедливого, мирного существования человеческой цивилизации.

The COVID-19 pandemic has affected all spheres of public life without exception. The education sector was one of the first to feel the impact of the coronavirus epidemic and reacted to the established restrictions by transferring all educational activities to a remote mode. The rapid transition of many educational processes to another format has caused the need for rapid adaptation to new conditions on the part of the state authorities, relevant ministries and directly educational institutions. Changes that are taking place in institutions of higher education concerning teaching methods, the approach to teaching itself, the formation of competencies among applicants for education, the organization of the educational process, which caused an ambiguous reaction among participants in the educational process. Such a crisis has served as an incentive for innovation in the educational environment. To ensure the continuity of education and professional training, cutting–edge solutions for distance learning are being developed and various innovative approaches are being used, because education is not just one of the basic human rights. This is a fundamental right, on which the realization of all other human rights directly depends. Education is a global common good, the most powerful driving force of progress to achieve goals in the field of development of society and the basis of an equal, just, peaceful existence of human civilization.

Chinese piano music has flourished for almost a century of history. The purpose of the article is to analyze literature and research materials on the history of Chinese piano music and art, as well as to provide a clear context and background information for colleagues studying the history of the development of Chinese piano art. This article examines the historical formation of piano education in China since the end of the 19th century. In the early period of learning to play the piano in the country, the creation of a number of new schools played an important role in promoting the development and popularization of musical culture. Shen Xingong and Li Shutong were outstanding representatives of piano education at that time. After the establishment of the Republic of China, Mr. Cai Yuanpei, who served as the head of education, issued a "Decree on temporary measures in the field of general education" and "Temporary standards of the curriculum of general education" for the whole country. All these educational reform documents consider piano teaching as the standard content of the new curriculum. In the 21st century, learning to play the piano is possible for many ordinary families. The increased interest in learning to play the piano reflects the general desire of the population for high art.
