Published: June 2023

Рациональность решения, которое принимается при проектировании морского порта, определяется возможностью рассмотреть как можно большее количество возможных сочетаний различных вариантов. Трудоемкость выполнения большого количества проектных расчетов приводит к необходимости ограничивать вариативность проработки решений. Для повышения эффективности проектной деятельности необходимо использовать современные методы компьютерных наук. В данной работе рассматривается задачу определения пропускной способности морского терминала на основании данных о границах территории терминала. Авторы предлагают использовать алгоритм, который строит различные варианты расположения склада терминала, параллельного или перпендикулярного к границам терминала. Результатами расчета алгоритма являются различные варианты расположения штабелей склада, их общая вместимость и пропускная способность всего терминала. Авторы рассматривают применение описанного алгоритма для формирования вариантов расположения склада контейнерного терминала. В работе доказывается, что предложенный метод может быть использован на предпроектных стадиях для определения наиболее рационального варианта расположения склада.

The rationality of a solution that is to be taken during a seaport’s design is defined by the capability to study as many different variants as possible. However, the labourness of the design calculations leads to the necessity to limit the number of variants. In order to increase the effectiveness of design calculations it is necessary to apply modern methods of computer science. The paper considers the task of automatic calculations of seaport’s throughput calculations based on its limits. The authors suggest a new algorithm to build different variants of storage yard configuration parallel or perpendicular to its limits. The results of the computation are different plans of container terminal storage yard, its total capacity and terminal’s throughput. The authors apply the suggested method to generated different plans of container yard. It is proved in the paper that the suggested method can be applied on the early stages of seaport’s design as a tool for definition of the most rational configuration of container yard.

Одной из самых спорных и плохо объяснимых формул, содержащихся в нормах технологического проектирования морских торговых портов, является формула расчёта объёма склада насыпного груза. В данной работе предпринята попытка интерпретировать эту формулу, а также внести в неё необходимые исправления. Для определения вместимости складской зоны идентифицированы методики вычислений, использующие средние значения (формула Уилсона, выведенная в рамках статьи формула-интерпретация норм технологического проектирования) и экстремумы максимальных значений (формула из норм технологического проектирования морских портов). Предлагается расширить расчётную методику, основанную на использовании этой формулы, для получения более адекватных оценок важнейшего инфраструктурного параметров - объёма склада морского перегрузочного комплекса. Целесообразно продолжить исследования об оптимальном размере склада на навалочных терминалах, в том числе используя накопленный эксплуатационных опыт и фактическую статистику терминалов (сроки и высота хранения угля, эксплуатационная производительность погрузки в суда, вместимости судов и др.).

One of the most controversial and poorly explained formulas contained in the norms of technological design of commercial seaports is the formula for calculating the volume of a bulk cargo warehouse. In this paper, an attempt is made to interpret this formula, as well as to make the necessary corrections to it. To determine the capacity of the storage area, calculation methods are identified that use average values (Wilson's formula, the formula-interpretation of technological norms derived within the framework of this paper) and extreme values of maximum values (formula from the technological norms of seaports). It is proposed to expand the calculation method based on the use of this formula in order to obtain more adequate estimates of the most important infrastructure parameters - the volume of the warehouse of the marine terminals. It is advisable to continue research on the optimal size of the warehouse at bulk terminals, including using the accumulated operational experience and actual statistics of the terminals (duration and height of coal storage, operational performance of ship loading, ship capacities, etc.).

The article presents additional approaches to the development of models for estimating labor intensity, providing reliability, low installation systematic error, the possibility of obtaining estimates, starting from the early stages of technical preparation of production and including the execution of work.
Calculation method of the flow induced by a disk of infinite radius rotates in a mass forces field
Authors: Яковлев А.Ю.
Published: June 2023

Одной из классических задач гидромеханики является задача Кармана о течении жидкости, вызываемом вращением в ней диска бесконечного радиуса. В настоящее время известны расширенные постановки данной задачи с учетом специфических свойств жидкости и ее поведения на границах потока. В данной работе рассмотрена задача Кармана в случае действия в жидкости массовых сил произвольной природы. Метод расчета этого течения предполагает задание в качестве исходных данных распределения массовых сил вдоль оси вращения диска. Задача решается в осесимметричной постановке, при этом распределение характеристик течения по радиусу определяется аналогично задаче Кармана. Особенностями разработанного метода являются переход к новой переменной, что позволило решать систему уравнений на конечном интервале, а так же применение метода математического программирования для решения краевой задачи. Разработанный метод был оттестирован на примерах классической задачи Кармана, и ее расширенной постановки Бэтчелора, в которой присутствует закрутка потока на бесконечности. Показана высокая точность получаемого решения. Метод был применен для нахождения решения в условиях действия массовых сил вблизи поверхности диска.

One of the classical hydromechanics problems is the Karman problem about the flow caused by the rotation of infinite radius disk in a fluid. Currently, extended formulations of this problem are known, taking into account the specific properties of the fluid and its behavior at the flow boundaries. In this paper, the Karman problem is considered in the case of the mass forces of arbitrary nature acting in a liquid. The calculation method of this flow assumes specifying the distribution of mass forces along the axis of disk rotation as initial data. The problem is solved in an axisymmetric formulation. Flow characteristics distribution along the radius determines similar to the Karman problem. The features of the developed method are the transition to a new variable, as well as the use of a mathematical programming method to solve a boundary value problem. The new variable made it possible to solving a system of equations on a finite interval. The developed method was tested by the classical Karman and Batchelor problems. The Batchelor problem is an extended formulation of Karman problem, in which there is a twist of the flow at infinity. The high accuracy of the obtained solution is shown. The method was applied to find a solution under the conditions of the mass forces action near the disk surface.
Numerical Simulation of Slip Flow and Heat Transfer of Biomagnetic Fluid over a Stretching Sheet in the Presence of a Magnetic Dipole with Temperature Dependent Viscosity
Authors: Murtaza M. G. , Alam Jahangir , Tzirtzilakis E. E. , Ferdows M.
Published: June 2023

The study of flow and heat transfer of biomagnetic fluid past a stretching sheet has a significant importance in a number of bio-medical and engineering applications including cancer treatment, drug delivery, magnetic resonance imaging, reducing blood flow during surgeries etc. Owing to these applications, the aim of the present paper is to study an electrically non-conducting Newtonian biomagnetic fluid in the presence of a magnetic dipole over an extendable sheet subject to velocity slip. The governing steady boundary layer equations with the help of similarity transformations were converted into a set of highly non-linear ordinary differential equations which are then computationally solved by applying the bvp4c function technique in MATLAB software. The results show that blood velocity and temperature can remarkably be influenced by the variation of ferromagnetic parameter. As the ferromagnetic parameter increases, the rate of heat transfer of blood is increased while coefficient of skin friction is reduced. We hope that this study could be useful in cancer treatment as well as in drug administration.
Estimating Seasonal and Interannual Variations in Precipitation in Rural Eastern Africa: A Case Study in Longido, Tanzania
Authors: Kuriakose Anoopa Susan , Walker Thomas William , Basu Onita
Published: June 2023

Access to water is a limiting factor for development in many semi-arid regions, contributing to food insecurity and environmental stresses on the local population. Additionally, some rural areas still have limited quantitative data on weather and associated rainfall patterns. This study analyzes ground meteorological data from a station installed at Longido, Tanzania and performs time series decomposition modelling of complementary Integrated Multi-satellite Retrievals (IMERG) data to quantify the amount, distribution, and variability of this essential resource. The seasonal rainfall pattern at Longido is bimodal with a large peak between March and May and a smaller peak between October and November. Interannual variability in rainfall is only weakly correlated with El Niño and the Indian Ocean Dipole indices; however, the highest observed rainfall does occur in a year with numerous simultaneous storms in the southern Indian Ocean. This analysis will help improve water management planning in the locality and points to a need to promote and support water storage as a method to meet the needs of the local population

Published: June 2023

The polyurethane foam material is commonly used and marketed in two forms, namely flexible and rigid. Flexible foam is used as a cushion, with various applications for commercial products such as chair support. Therefore, this study aims to describe the occurrence of a fire situation in a university room filled with many polyurethane foam chairs. It also aims to provide awareness regarding potential flame hazards, by using a fire modelling method with FDS. The results showed that fires on PU foam materials produced a high HRR and a wide spread of flame and smoke. From this context, the harmful effects of the fire on the room occupants were emphasized. The results obtained are expected to support the theory of compartment fire, flame distribution in solid materials, PU Foam inferno behaviour, etc. It is also expected to provide additional fire protection and evacuation training for room occupants.

Authors: Muis Alwas , Sunardi Sunardi , Yudhana Anton
Published: June 2023

Brain tumor is one of the most fatal diseases that can afflict anyone regardless of gender or age necessitating prompt and accurate treatment as well as early discovery of symptoms. Brain tumors can be identified using Magnetic Resonance Imaging (MRI) to detect abnormal tissue or cell development in the brain and surrounding the brain. Biopsy is another option, but it takes approximately 10 to 15 days after the inspection, so technology is required to classify the image. The goal of this study is to conduct a comparative analysis of the greatest accuracy value attained while classifying using segmentation with thresholding versus segmentation without thresholding on the CNN method. Images are assigned threshold values of 150, 100, and 50. The dataset consists of 7023 MRI scans of four types of brain tumors: glioma, notumor, meningioma, and pituitary. Without utilising thresholding segmentation, the classification yielded the highest degree of accuracy, 92%. At the threshold of 100, classification by segmentation received the highest score of 88%. This demonstrates that thresholding segmentation during CNN model preprocessing is less effective for brain image classification

Does The Indonesian National Standard (SNI) for Products in SMES Influence Cleaner Production Practices? A Snapshot of Best Practices from Yogyakarta, Indonesia
Authors: Rosyidi Muhammad Imron , Budiastuti Maria Theresia Sri , Rahardjo Mugi , Gunawan Totok
Published: June 2023

This article investigates the extent to which the Indonesian National Standard (SNI) for products adopted and applied by small and medium enterprises (SMEs) in Yogyakarta, Indonesia, can encourage them to effectively implement a quality management system (QMS) within their internal organizations, which eventually affects and benefits their process performance and clean production practices. Survey data collected from 44 respondents in 12 SMEs with SNI-certified products were processed and examined using descriptive analysis and regression analysis. The results showed that these could implement QMS effectively partly because it is a requirement for the SNI certification of the proposed product. The effectiveness of QMS implementation affects the achievement of process performance in that it can reduce the number of defective products, process costs, and process cycle times. According to the respondents, an effective QMS makes every activity and action taken in the production process more environmentally friendly and leads to cleaner production practices. These findings can help further research determine the model's feasibility to design and develop a better framework that promotes QMS and clean production practices, especially among SMEs in Indonesia.

Published: June 2023

Design for manufacturing and assembly (DFMA) is widely applied in many industries to optimize the manufacturing and assembly process at the early stage of design, with the aides of the CAD model. Many researchers apply the DFMA to increase assembly efficiency, by decreasing the number of parts from a product, decreasing the manufacturing cost, and reducing assembly time. Therefore, this research applies DFMA to develop exhaust fan housing with ceiling mounting for high rise building type with the same purpose, and at the same time to justify that the method can overcome the problem of assembly time in a production line. Both designs from before and after the application of DFMA, are being compared by using finite element simulation and experimental. The simulation employs stress analysis, to predict the strength of those designs. While the experimental uses a manufacturing cost survey, real assembly time survey and failure test to show the advantages of DFMA design results. The research result shows that the DFMA method can decrease the manufacturing cost by 0.44%, and the assembly time by up to 2%, and able to withstand the entire mass of the ceiling mounting fan.
Failure Investigation of Blank Holder Force (BHF) Control in The Outside Bracket For Front Seat
Authors: Romansyah Rofan Yulian , Budiarto Hanif Azis , Erlangga Yuliar Yasin , Safrudin Yunita Nugrahaini
Published: June 2023

This study investigated the failure of the Blank Holder Force (BHF) control in the outside bracket for the front seat. The production process involved progressive dies consisting of nine stations: first pierce, first trim, second trim, idle, flange, idle, second pierce, idle, and parting. However, at the 7th-9th station, the pilot hole in the product deforms into an oval shape, which is undesirable. Gemba-Kaizen methods were used in this study, and primary data were collected by comparing the design and actual progressive dies. The results showed that product defects are primarily caused by an unbalanced BHF and inadequate piercing clearance. A uniform distribution of force during the forming process is obtained by reducing the spring number on the blank holder. This reduces the force generated during the process. Furthermore, the die clearance was increased from 0.01 mm to 0.1 mm, making press and die alignment less critical and requiring less cutting and stripping forces

Published: June 2023

Implementing IT innovation in organizations is a complex and challenging process that affects organizational problems. The process involves many interacting factors and actors; hence this situation is difficult to control. This problem demonstrates the need to understand researchers' perceptions of IT adoption and implementation. This study aims to explore in depth the adoption and implementation of self-development IT applications (SDIT) in Islamic-based Higher Education Institution (IHEI) in Indonesia. The IT Adoption and Implementation Framework (Irawan et al., 2018) was applied as a lens to investigate the case. We conducted in-depth interviews with key informants involved during the adoption and implementation process in the organization. Interviews were transcribed and analyzed using thematic analysis. Certain Focus Group Discussion (FGD) studies and specific interviews with key informants representing three levels of management explained that mediating factors such as post-implementation interventions, subjective norms, and facilitating conditions influence success in adopting and implementing IT innovations in such cases. This study concludes that managerial interventions play an important role in reducing resistance from authoritarian approaches to mandating use and serve as a determinant of its sustainability in the future. These findings have significant implications for understanding how to achieve success in IT adoption and implementation in the post-implementation phase by providing empirical evidence. Theoretically, this study contributes to IT adoption and implementation frameworks by identifying the active role of critical actors in the adoption and implementation of IT applications in higher education institutions.

Authors: Campit Joseph B.
Published: June 2023

The study aimed to compare the classification performance of Support Vector Machine (SVM) and Naive Bayes (NB) machine learning models for estimating customer satisfaction utilizing Filipino text. Specifically, it analyzed the characteristics of the customer satisfaction data. It also examined the impact of different model configurations, including n-gram, stop words, and stemming, on the classification performance of the two models. The research employed qualitative and quantitative methods, utilizing text analytics and sentiment analysis to extract and analyze valuable information from unstructured responses from a satisfaction survey of the University President’s leadership performance conducted among PSU personnel and students. The dataset comprised 56,000 Filipino and English-word responses, manually annotated and randomly split into training and testing datasets. The study followed a general framework encompassing data pre-processing, modeling, and model comparison. To validate the classifiers’ classification performance, a 10-fold cross-validation approach was employed. The findings revealed that most personnel and students expressed positive sentiment toward the University President’s leadership performance. SVM outperformed the NB model across all different model configurations. With both stop word removal and stemming, the SVM trigram model achieved the highest classification performance for estimating customer satisfaction, using 75% of the data for training and 25% for testing. The proposed model holds the potential for estimating customer satisfaction using other unstructured customer satisfaction data utilizing Filipino text.

Published: June 2023

The consumption of electrical energy is increasing due to problems related to the deficient energy supply in certain localities, which affects the basic needs in rural communities where, currently, the efforts to distribute electricity by the authorities, through common technologies, are not enough. On the other hand, there is also the problem of the overexploitation of non-renewable energies, which produce large amounts of C02. To reduce these problems, renewable energies that do not generate polluting waste are used, but the ability of engineers is needed to achieve prototypes that give good results. The purpose of this research is to carry out the design and simulation of a control system and redesign of a Vortex wind turbine mast to keep it in resonance and generate electrical energy. The study objectives are met by verifying the specific results through requirements analysis, simulation design, and system validation. As a result, the parameters to generate vortices and keep the system in resonance were identified. In addition, the redesign of the mast of the Vortex wind turbine was obtained.

Vid årsskiftet 1998–1999 återfördes en unik fotosamling till hemtrakterna i Österbotten, inte ända hem, men nästan. Samlingen, som donerades till Folkkultursarkivet vid Svenska litteratursällskapet i Helsingfors år 1972 och där tillvaratogs av de framsynta etnologerna och arkivarierna Bo Lönnqvist och Ivar Nordlund, hade skapats av fotograf Erik Hägglund i Vörå. Den består av uppskattningsvis 40 000 glasnegativ. Nu utgör den en del av det material som uppbevaras vid Österbottens traditionsarkiv i Vasa. Traditionsarkivet är en avdelning inom Folkkultursarkivet och är geografiskt beläget ca 40 km från den ort där samlingen har uppstått. Det speciella med Erik Hägglunds fotosamling är att den tidsmässigt omspänner ett halvt sekel. Också på grund av sin numerära omfattning dokumenterar den livet på den österbottniska landsbygden på ett unikt sätt. I arkivets verksamhetsplan ingår att skanna, identifiera och införa glasnegativen i en bilddatabas. Vid utgången av år 2006 innehöll databasen uppgifter om närmare 18 000 negativ. Summerat med det vid Folkkultursarkivet skannade materialet, närmar sig de i databaserna inmatade bilderna 22 000. Samlingens omfattning har lett till en sållning av materialet under år 2007, vilket innebär att endel motiv inte skannas utan endast införs i en databas med tillgängliga uppgifter.

Authors: Vaughan Tanya , Richardson Sarah , Carslake Toby , Reimers Trisha , Macaskill Greg , Newton Toby , Zoanetti Nathan , Mannion Andrew , Murphy Martin
Published: June 2023

The Australian Council for Educational Research (ACER) was commissioned by the Teachers and Teaching Research Centre (TTRC) at the University of Newcastle to conduct an independent randomised controlled trial (RCT), with the goal of examining effects of Quality Teaching Rounds (QTR) on student outcomes and teachers’ practice in Victorian high schools. A total of 19 schools participated in Quality Teaching Rounds in 2022, with 20 schools in the wait list control. Data were gathered in an ongoing manner during the evaluation with: Progressive Assessment Tests in Mathematics (PAT-M) and reading (PAT-R) – baseline and follow up; student self-efficacy and aspiration surveys – baseline and follow up; teacher surveys – one questionnaire administered every term; implementation fidelity check surveys for teachers to complete for each QT Round; and implementation fidelity checks with onsite visits from ACER staff for 33% of the treatment schools. Key findings include: The mixed model analysis showed that treatment was not a significant predictor of PAT-R and PAT-M outcomes. Differences in student responses to the self-efficacy and aspiration surveys were identified. The control group showed a significant increase in the level of education that they aspired to complete (p = 0.037). Teachers in the control group had statistically significant growth in teacher efficacy, while those in the treatment group showed statistically significant lower teacher student support. Within the QTR process, the longest time was spent on discussing the coding and the individual coding process. Key observations identified from analysis of the fidelity check data are: teacher stress due to high rates of absenteeism, varied use of the Classroom Practice Guide, and analytical conversations about some elements and terms.

The Eviews application version 12 is used to analyze the data from both models. The findings indicate that leverage has a strong favorable impact on profit management. While Sales Growth has no discernible impact on Profit management. Meanwhile, while good corporate governance can moderate the impact of leverage on profit management, good corporate governance cannot moderate the impact of sales growth on profit management.
El Libertador San Martín y la educación pública peruana en los años 1822-1823
Authors: Arce Rodrigo
Published: June 2023

La corriente libertadora del sur implementó una educación adecuada a toda la población del Perú recién independizado. Esta investigación tiene como objetivo describir características de la educación pública propuesta por José de San Martín en los años 1822-1823. Antes de su llegada, la educación era impartida mayoritariamente por clérigos, en la que sobresalieron los jesuitas, pero que ya habían sido expulsados del país. Muy poca población podía costearla, pues los útiles escolares y la renta de los profesores eran caros, y había escasez de espacios adecuados para impartir clases. No existían centros de capacitación de profesores y la cantidad de maestros no era suficiente para la nueva época. El gobierno adopta la enseñanza mutua o lancasteriano, por sus bajos costos de inversión en capacitar profesores y en materiales de estudio. Es un tipo de investigación básica, histórica de enfoque cualitativo. El diseño de la investigación es de tipo no experimental y transversal, cuya característica es la compilación de datos. La técnica de recolección de datos abarca los documentos escritos, como inscripciones, correspondencia epistolar, informes, libros de apuntes, obras literarias, diccionarios, actas de fundación, periódicos, revistas, memorias, y otros. Los instrumentos son las fuentes históricas, copiados en fichas bibliográficas.

Published: June 2023

La presente investigación se propuso determinar la influencia de las herramientas digitales de organizadores gráficos en los niveles de desarrollo del pensamiento conceptual en los estudiantes de 7° de básica secundaria. Se realizó un diseño de preprueba/postprueba con un solo grupo, iniciando con el diagnóstico del desarrollo del pensamiento conceptual en los estudiantes mediante la aplicación de la prueba de pensamiento concreto de seriación y clasificación planteadas en la tercera etapa de la teoría del desarrollo cognitivo por Piaget (1954) para determinar el nivel de desempeño de los estudiantes. Posteriormente, se diseñaron guías didácticas en la asignatura de castellano y se aplicaron en las siguientes fases secuenciales: procedimental, desarrollo de ejercicios, actividades de finalización y práctica de trabajo independiente del estudiante con una metodología de integración para el desarrollo de destrezas y procesos mentales asociados al pensamiento conceptual y sus relaciones cáusales de tipo literal de Ariño (2017). Los resultados mostraron una mejora en los niveles de desarrollo del pensamiento conceptual en los estudiantes de 7 ° de básica secundaria.
Debido procedimiento administrativo sancionador y el control judicial como tutela jurisdiccional efectiva
Authors: Mendoza Giraldez Elizabeth
Published: June 2023

En este estudio, profundizamos la investigación acerca del procedimiento administrativo como un conjunto de actos y diligencias tramitados en las entidades, conducentes a la emisión de un acto administrativo. En esa línea, cabe señalar que, el trámite administrativo punitivo, es la conjunción de acciones relacionadas al control administrativo. Bajo este criterio, la atribución de castigo que faculta a la administración del Estado, se sostiene en la autotutela administrativa. Los administrados, por lo cual, tienen atribuciones y garantías que van en concordancia al debido proceso. Asimismo, en el presente artículo, se demostró que la relación de la potestad sancionadora de la administración pública con el control judicial como tutela jurisdiccional efectiva, se da por las razones prismáticas que justifican las facultades coercitivas que contemplan las normas legales. En conclusión, consideramos que el marco legal constitucional interviniente como última ratio, de control jurisdiccional, solo se pone de manifiesto en la medida en que la normatividad lo permita, se cumplan los requisitos previos y se haya agotado el principio de la no vulneración de los Derechos Fundamentales en la administración pública.

El trabajo de investigación tiene como finalidad promover un modelo interactivo de enseñanza aprendizaje en la asignatura de Fundamento de programación lenguaje C++  mediante la plataforma digital Educalim para estudiantes de primer semestre de la Facultad de Telecomunicaciones de la Universidad Upse del Cantón La Libertad, considerando una muestra de 60 estudiantes de la institución de educación superior. Se aplicó un estudio de investigación descriptiva, con un enfoque práctico y técnicas de recolección de datos, en las que se usaron instrumentos como: observación, y encuesta. La fundamentación teórica se sustenta en los antecedentes establecidos por Areces, (2017) y Aros, (2018) que analizaron las dificultades del aprendizaje de las matemáticas, la doctrina docente, la enseñanza tradicionalista en los procesos de enseñanza y las causas que traen consigo estas prácticas en la actualidad; por otro lado Caizaluisa, (2018) y Bolaños, (2020) promueven desde entonces el uso de los recursos educativos digitales como mejora a la enseñanza aprendizaje del lenguaje de programación. Estos antecedentes permitieron plantear una encuesta de satisfacción a los estudiantes con la finalidad de obtener información oportuna sobre la realidad de los procesos educativos en la institución, se tabulan datos y se genera una propuesta a corto plazo en que se da uso a recursos educativos digitales como: videos tutoriales, Moodle, plataformas virtuales; que aportan significativamente al aprendizaje del estudiante.

El proceso fundamental del estudio es identificar los factores que inciden en la deserción académica del sistema educativo del Ecuador, por medio del análisis de la información de las diferentes instituciones educativa. El tipo de estudio se enmarca en el enfoque cuantitativo, por lo cual, el diseño de la investigación fue no experimental, de corte descriptivo de carácter longitudinal, para el análisis de la información empírica se tomó en cuenta las bases de datos del Instituto Nacional de Estadística y Censo del Ecuador, sobre la encuesta del sistema educativo a nivel nacional; cada base de datos fue segmentada según el sexo, área geográfica, régimen escolar y jurisdicción. Respecto a la unidad observacional temporal (2010 a 2021).  Los resultados muestran que la tasa de deserción escolar en el Ecuador tuvo un aumento entre el periodo 2010 al 2012 y luego comenzó a disminuir. También se observó una diferencia por género, donde las mujeres experimentaron un aumento inicial, pero luego una disminución, mientras que los hombres experimentaron un aumento inicial más pronunciado. Además, la brecha entre el área urbana y rural en cuanto a la tasa de abandono escolar no ha sido significativa en los últimos 12 años analizados. Aunque se han registrado algunos cambios, la brecha nunca superó el 1%. El abandono escolar en el Ecuador es un problema complejo que involucra una variedad de factores. Si bien las dificultades económicas parecen ser el factor más significativo que contribuye al abandono escolar, la falta de acceso a la educación, el bajo rendimiento académico, los problemas familiares y de salud.
