Authors: Alcaíno Manuel , Jaimovich Analia , Lerche Sofía , Méndez Carolina , Ortiz Guerrero Marcela , Vidal Eloísa
Published: December 2022

Este artículo describe la experiencia de gestión educativa en el municipio de Aracruz, en el estado de Espírito Santo, Brasil. El municipio de Aracruz presenta una mejora sostenida en la educación primaria de sus escuelas, registrando el salto más importante entre los municipios urbanos grandes del estado. Algunos de estos resultados se dan en el marco de una importante inversión de la Secretaría Municipal de Aracruz (SEMED) en la consolidación de una función de acompañamiento pedagógico a directores/as escolares y en la implementación de innovaciones en la gestión de la información y sistemas de evaluación local. Un componente clave de esta experiencia es la continuidad de un cuerpo técnico formado por docentes que reparten su jornada laboral entre la escuela y el departamento de educación. La elaboración del Plan Municipal de Educación 2015 - 2025 representa la expresión de un trabajo que se viene realizando en Aracruz, que culmina en: i) la organización de un sistema robusto de supervisión de las escuelas para el seguimiento y acompañamiento técnico-pedagógico; ii) creación de un sistema municipal de evaluación diagnóstica que frecuentemente alimenta a las escuelas sobre el dominio de los estudiantes en diferentes materias; y iii) la implementación de un sistema de gestión de la información escolar que apoya a los equipos de las escuelas y de la SEMED para el seguimiento actualizado de las prácticas educativas. Esta tríada de iniciativas, que funcionan de manera articulada, fortalece un mecanismo interno de rendición de cuentas, coordinación y optimización de esfuerzos entre equipos y asegura una asistencia efectiva a las escuelas.

Authors: Zambrano Omar , Hernández Hugo , Granado Albani , Quiroz Gabriel , Gómez José Gregorio , Benzecry Ricardo
Published: December 2022

El éxodo masivo de venezolanos ha sido uno de los temas más importantes en los últimos años debido a sus implicaciones sociales, económicas, políticas y regulatorias. Se estima que el número de refugiados y migrantes venezolanos en el mundo superó los 6 millones de personas en febrero 2022. Muchos venezolanos han optado por emigrar para tener mejores condiciones de vida y también para contribuir a mejorar la situación económica de sus familias a través del envío de remesas. Desde 2016, el envío de remesas ha sido una fuente creciente de ingresos para una gran parte de hogares venezolanos. Se utilizan datos de la Encuesta Nacional de Condiciones de Vida para evaluar el aporte de las remesas al ingreso de las familias receptoras y su impacto distributivo, así como para reflejar el papel que desempeñan en la pobreza por ingreso. Los resultados del estudio sugieren que el 18% de los hogares son receptores de remesas, sin embargo, el promedio de remesas recibidas esconde una gran heterogeneidad. El flujo de remesas tiende a ser regresivo en el sentido que su peso como proporción del ingreso total es mayor en los hogares más ricos. Las remesas representan un importante complemento del ingreso familiar, con un rol creciente en el sostenimiento de su bienestar.
Financial Solutions for Development: National Infrastructure Platforms
Authors: Ketterer Juan , Ortega Andrade Adrián , Martínez Álvarez Juan , Fonseca Daniel
Published: December 2022

This paper presents a new public policy instrument, national infrastructure platforms (NIPs), to promote investment in sustainable infrastructure in Latin America and the Caribbean. The region has important infrastructure deficits that limit its ability to meet challenges of economic growth, climate change, and social inclusion and equality. NIPs will allow countries to maximize the use of public, multilateral, and concessional financing resources to promote socioeconomic development. Specifically, since the infrastructure challenges of the region will not be met with public funding, NIPs will permit countries to optimize the role of public investment as a financial enabler for private investment, prioritizing climate change resilience through sustainable infrastructure. This document outlines the structure of NIPs and their three main functions: project preparation, de-risking, and financial structuring. These respectively identify and prioritize projects, incorporate the necessary risk mitigation instruments, and structure and deliver bankable projects until they successfully reach their commercial and financial closing stages.

Authors: Villasmil Ricardo
Published: December 2022

El documento se centra en comprender el impacto que la migración masiva de venezolanos ha tenido tanto en los familiares que permanecen en el país como en Venezuela como país de origen. Se examina la crisis humanitaria y se destaca su rol como determinante fundamental de la migración. Se caracteriza a esta última en términos de su destino y de sus características socioeconómicas en particular y se contrastan los resultados con la evidencia empírica en materia de migraciones masivas. Concluimos que la migración venezolana ha sido consistente con la selección positiva y la discriminación positiva y que ha estado signada por un fuerte sesgo hacia personas jóvenes, lo cual ha tenido un impacto importante en la estructura de edades y en la tasa de crecimiento poblacional. Finalmente, se estima la pérdida de capital humano asociada a la migración venezolana y se realiza una aproximación al ndice de Capital Humano de Venezuela.

Published: December 2022

El acompañamiento pedagógico a las instituciones educativas es una de las funciones clave de las Unidades de Gestión Educativa Local (UGEL) del Perú. En el presente estudio se analiza el Programa Integrado para la Mejora de los Aprendizajes de la UGEL Chucuito en la región de Puno. Este programa, implementado desde 2017, cuenta con cuatro iniciativas orientadas a responder a las necesidades de asistencia técnica de los directivos y docentes: (1) Escuelas Maestras Innovadoras; (2) Redes Educativas Vivas; (3) Grupos de Interaprendizaje; y (4) Sistema de Formación Permanente SISFOPERCH. A través de una descripción de la arquitectura institucional del sistema educativo peruano se busca comprender las funciones de la UGEL y su interacción con los otros niveles del sector, para luego conocer en qué consiste el programa destacado. Además de la descripción del programa, se presentan los desafíos institucionales que la UGEL Chucuito ha debido sortear durante su diseño e implementación. Esta iniciativa se destaca porque se hace cargo de la problemática de la gestión pedagógica en zonas rurales andinas con dificultades de acceso y conectividad, sitúa el bienestar integral del docente en el centro de sus intervenciones y, al mismo tiempo, impulsa las innovaciones pedagógicas y la vinculación con el medio a través de la generación de alianzas estratégicas con instituciones locales y nacionales para la implementación de sus proyectos.

Authors: Ansoleaga Antonio , Fretes Santiago , Valencia María Paula
Published: December 2022

La presente nota técnica desarrolla una visión analítica sobre la efectividad de las operaciones con garantía soberana y sus determinantes -con un foco especial en CSC-, con el objetivo de generar lecciones para el trabajo operativo que permitan aumentar la probabilidad de impacto/éxito de las operaciones a futuro. A través de un enfoque cuantitativo, se analiza el efecto de distintos determinantes revisados en la literatura sobre la probabilidad de éxito de las operaciones, encontrando que, tanto por magnitud como por significancia estadística, las variables de diseño y capacidad institucional aparecen como las más relevantes para explicar la efectividad de las operaciones, según el modelo y la data utilizada. Si bien el análisis cuantitativo permitió dirigir la atención a aquellas variables identificadas como relevantes para explicar la efectividad de las operaciones, éstas aún encierran una gran heterogeneidad en su interior constituyéndose en una especie de “caja negra”-, la que se exploró, en una segunda etapa, a través de un enfoque cualitativo (estudio de casos y entrevistas a actores clave) para obtener recomendaciones operativas concretas.
Kant's Copernican revolution as an altered method of thinking [in metaphysics]: its structure and status in the system of transcendental philosophy
Authors: Katrechko Sergey
Published: December 2022

Kant’s transcendental philosophy of Kant is the metaphysics of possible experience related to the solution of the [semantic] problem set in his famous letter to M. Hertz (02.21.1772): “What is the ground of the relation of that in us which we call 'representation' to the object?” There are two possible ways to solve it: empiricism and apriorism, – and Kant chooses the second of them, thus making his “Copernican Revolution”. In the Preface to the 2nd ed. Critique Kant correlates his Copernican turn/revolution with "altered method of our way of thinking [in metaphysics]" [BXVIII] and considers it as an analogue of the hypothetico-deductive scientific method of Copernicus – Galileo – Newton. The analysis of structure of the Copernican Revolution shows that it is possible to pick out two vectors: the empirical (from the thing-in-itself to representations) and the noumenal ones (from the transcendental unity of apperception [or transcendental object] to objects of experience). The introduction of an a priori vector (resp. a priori forms) means that Kant's conception is not empirical, but Kant’s keeping empirical vector says that it is compatible with empirical realism [A370–1]. Thus, Kantian transcendentalism is a synthesis of realism (basic level) and transcendental idealism (as a meta-level superstructure above it), whose task is to find out and analyze the transcendental conditions [possibility] of our knowledge of objects.
The Question Answered: What is Kant’s ‘Critical Philosophy’? (Translated by Alexey Zhavoronkov)
Authors: Westphal Kenneth R.
Published: December 2022

This paper answers the question, what is Kant’s ‘Critical Philosophy’? The answer is not provided by a bibliography of Kant’s main works, nor by his transcendental idealism. The answer consists in Kant’s critique of our human capacity to judge and of those rational principles by which we can properly judge matters accurately and cogently. To show this, three key features of Kant’s critique of rational judgment are examined: Five constitutive characteristics of our human capacity to judge (§2), two basic theses of Kant’s Critical Philosophy (§3) and a table of basic systematic questions and their Critical answers (§4). This conspectus is philosophically significant because it clearly identifies Kant’s Critical method and its key considerations, which continue to be widely neglected when considering philosophical method (§5).

Authors: R Priyanka R , Kaur Harpreet , Kharbanda OP , Priya Harsh , Sood Anubhuti , Mishra Deepika
Published: December 2022

Background: E-cigarettes have been perceived as a safer product compared to conventional cigarettes and have often been used for the purpose of cigarette smoking cessation. The aim of this scoping review is to provide a systematic review of the existing literature on the effects of e-cigarettes on human oral health and oral tissues. Methodology: Systematic literature search was undertaken and reviewed independently by two experts in online databases till May 2019. Both human and invitro studies were included. Guidelines of preferred reporting items for systematic reviews and meta-analyses for scoping reviews (PRISMA-ScR) were followed for reporting of the data. Results: A total of 24 studies were included following removal of duplicates, title and abstract screening and; full text screening. E-cigarettes have deleterious effects on the oral cavity tissues comprising of clinical findings of periodontium, gingiva, oral hygiene and micro-organism growth. In addition, there is a threat of serious injuries associated with e-cigarette explosion. In-vitro studies reveal e-cigarette use may lead to oxidative damage, altered morphology, reduced cell viability and cytotoxicity of oral epithelial and fibroblast cells. Conclusions: Though e-cigarettes have been found to be less harmful than the conventional cigarette smoking, there is a need to exercise caution while considering it as a smoking cessation tool. Longitudinal population-based studies are required for analyzing its in-vivo effect on oral tissues.
91 Soruda İmâmiyye Kelamının Özü: Şeyh Müfîd’in en-Nüket fî Mukaddimâti’l-Usûl Adlı Eserinin Tercümesi ve Değerlendirmesi
Authors: ALTUN Bekir
Published: December 2022

Şeyh Müfîd, hayatı boyunca İmâmiyye kelamını geliştirme ve rasyonelleştirme çabası içerisinde olmuştur. Bu uğurda birçok eser telif etmiş ve eserlerinde farklı metodolojiler denemiştir. Kendisinden sonrakilere yol haritası olacak bir eser olarak ise en-Nüket fî Mukaddimâti’l-Usûl adlı eseri kaleme almıştır. Zira İmâmiyye’de kelamî meselelerin nasıl ele alınacağına dair önemli ipuçları sunmakta ve bir kelam metodolojisi ortaya koymaktadır. en-Nüket, onun sistematik olarak kaleme aldığı ilk eseri olmakla birlikte İmâmiyye içerisinde de ilk sistematik kelam eseri olma hüviyetine sahiptir. Öncelikle İmâmiyye kelamına ait terimlerin anlamını verdikten sonra sırasıyla tevhîd, nübüvvet, imamet, va‘d ve va‘îd, konularını sistemli bir şekilde ele almıştır. Dikkat çeken husus ise girişte adalet ile ilgili bazı kavramların anlamlarını vermesine rağmen (muhtemelen yazma nüshalardaki tahrifattan kaynaklı) eserin sistemi içerisinde bir prensip olarak adalet bahsine yer vermemiştir. Eserde muhteva ve metot yönüyle Mu’tezilî düşüncenin, özellikle Kâdî Abdülcebbâr’ın etkisi görülmektedir. Bu çalışmada öncelikle Şeyh Müfîd’in en-Nüket fî Mukaddimâti’l-Usûl adlı eserinin içerik ve üslup açısından değerlendirmesi yapılarak eserin Müfîd’e aidiyeti ile ilgili tartışmalara değinilmiştir.

Justice and Community, Ancient and Modern
Authors: Anastaplo George
Published: December 2022

That great byproduct of the scientific enterprise, technology, has opened the way to what we know as globalization, making it easy to abandon thereby the age-old question of what size community is best for the human being and for justice, a question reflected in what Aristotle had to say about the merits (as well as, perhaps, about the limitations) of the polis. Does the opening to globalization mean that we can no longer believe that we can (or even should) ever again control our lives by shaping the communities in which we live? This essay explores this issue drawing for inspiration upon a variety of literary texts, ancient and modern, including works by Shakespeare, Euripides, Aristophanes, and Aeschylus.

"Philosophical faith” and mystical experience: Convergence and divergence
Authors:   Yuri Gagarin State Technical University of Saratov, Duplinskya Yuliya M. , Friauf Vasiliy A. ,   Saratov State University
Published: December 2022

Introduction. The common version that mystical experience reveals the deep unity of religious traditions, hiding behind the external facade of their differences, seems controversial. Theoretical analysis. It is justified that the similarity between different traditions of mysticism does not express the quintessence of religiosity, as such, but only convergence in a certain phase of the evolution of religions. Mysticism is compared with the entry of religion into the phenomenological phase of development. Mysticism, like philosophical phenomenology, is turned to the experience of consciousness. Phenomenology forms the common space of meeting for mystical experience and the experience of philosophical faith. Phenomenological experience is similar to the “energy minimum” of mystical states. Like the state of heat death in thermodynamics, this is a kind of common denominator, at which all mystical traditions are aimed in the process of devolution, and then desacralization. After the mystical-phenomenological phase, religious consciousness is reoriented from the phenomenological Presence to the eschatological Coming. Here the trajectories of divergence are again indicated. Conclusion. From the standpoint of Orthodox ascetics, the philosophical faith, as a phenomenological version of mysticism, is insufficient, because it is associated only with a change in consciousness. The true experience of God’s message in Christianity requires the transformation of everything - including the flesh of human nature.
From the subject to the agent in social and humanitarian discourses of the 21st century
Authors:   South Ural State University (National Research University), Penner Regina V.
Published: December 2022

Introduction. The article is focused on the problem of tuning research optics in the directions of vision and understanding a subject, society and the whole world. Since the Age of Enlightenment, the idea of subjectivity has been the foundation for such optics. In the 21st century the place of the subject is claimed by multiple agents that do not have a human nature. Theoretical analysis. In addition to nature as such and the organisms inhabiting it, the role of agents today is being played by instruments and technologies, including digital technologies. In order to trace the development of the idea of agency in social and humanitarian discourses, the article is based on the concepts of modern authors who carry out their research within the framework of the so-called queer theory (posthuman by R. Braidotti, companion species by D. Haraway and A. Tsing, agential realism and intraactivity by K. Barad). Conclusion. In posthumanistic logic, the contemporary world can be perceived as a smooth, heterogeneous space (G. Deleuze). In this “smoothness” it becomes more and more difficult to single out one or another element that is capable of performing the function of a structuring beginning, hierarchizing the external.The article concludes that the understanding of a person, society, nature and technology through the agential prism will clarify research optics in the context of social and humanitarian discourses.
Personal maturity: A research model in the context of an event approach
Authors:   Donetsk National University, Andryushkova Nadezhda P.
Published: December 2022

Introduction. The problem of personal maturity, its criteria and mechanisms of achievement, acts as one of the significant and urgent problems in modern psychological science. A large number of scientific papers are devoted to the interpretation and definition of this concept, the search for its content and structural elements. Theoretical analysis. Based on the systematization of theoretical material, the author builds a model for the analysis of personal maturity (in the context of the event approach). In this model, there are blocks that can act as parameters of personal maturity: event block, reflexive block, semantic block, behavioral block. Conclusion. Conclusions are drawn that significant personality events can act as possible initiators of the formation of personal maturity, and are defined in the event block of the study. The mechanisms of experiencing a crisis event, forming unity with reflexive processes, constitute (a reflexive block of research). Comprehension of the situation, construction of new meanings (semantic block of research). Adaptation to new conditions, situational activity (behavioral research unit). The author believes that the data obtained can be used for a more detailed analysis of personal maturity, the conditions for its actualization, as well as for the construction of models of empirical research of personal maturity.
Forming a tolerant attitude of foreign students to Russian culture in the process of aesthetic education
Authors:   Volsk Military Institute of Material Support, Romanova Viktoriya V.
Published: December 2022

Introduction. The education of tolerance has been of interest to scientists since ancient times. Theoretical analysis. A comparative analysis allows us to conclude that the concept of “tolerance” should be defined from different positions: some researchers emphasize the idea of mutual respect and equality, others underline not so much respect and tolerance for other people, regardless of race, religion, social status, etc., but more the influence of tolerance on the process of human socialization; others pay special attention to the spiritual component of the concept of tolerance, referring tolerance to the criteria of moral upbringing of the individual. Consideration of the problem of tolerance education made it possible to identify the mechanisms of its development. Conclusion. In order to form a tolerant attitude towards Russian culture in foreign students, it is necessary to develop their interest in Russian culture and teach them to adequately understand the unfamiliar surrounding reality, to be able to focus on appropriate behavior and communication in the Russian-speaking society. The formation of a tolerant attitude towards Russian culture is influenced by classes in Culture of Speech, in which emotionally colored situations of creativity and communication should be used. The most important components of the tolerant attitude of foreign students to Russian culture are the culture of speech and communication.
Optimization of Mutation Testing Challenges to Fixing Faults
Authors: Arnomo Sasa Ani , Ibrahim Noraini , Dasa Putri Anggia , Hutabri Ellbert
Published: December 2022

One of the challenges of mutation testing is fixing faults. In the debugging phase, all live mutants were repaired. Programs need high mutation scores to be declared reliable program codes. Each mutation test can allow the identification of multiple mutants. This is what confuses the faults fixing process. The objective of this research is to get the shortest route so that it can help in sorting the mutant types during application improvement after testing. The optimization is needed considering the number of mutants in each mutation testing. The problems related to optimization are very complex. It takes a suitable method to find the shortest path by paying attention to each point. There are 30 projects chosen randomly. The operator mutations that are often killed when testing mutations are AOIU and COI. The proposed optimization for mutant repair sequence is the ant colony system (ACS). The route selection using the Ant Colony System algorithm resulted in route optimization of 1.528254. Meanwhile, if the genetic algorithm is used, the score is 1.767643. Optimization results are very helpful for developers in improving code in mutation testing. Research states the best order for handling mutants using ACS. This research can be further developed with the addition of class-level mutant cases which are produced using class mutation operators. Class mutation operators have different characteristics from traditional mutation operators. In particular, it requires changes to the program structure, such as the definition of class variables.
Incremental Knowledge-based System for Recommending Content Adaptation in Dynamic Learning Environment
Authors: Muhammad Alva Hendi , Ariatmanto Dhani , Yuhefizar -
Published: December 2022

Dynamic learning environment (DLE) provides an opportunity for students with a remarkable learning experience in a limited time and specific situations. In this condition, adaptation and personalization have been key issues to accommodate differences between students. Both paradigms emphasize tailoring learning activities to studentsâ€™ understanding and interest through learning objectives, instructional approaches, and learning pathways. In addition, the students will learn optimized instructional activities at their own pace. This paper presents an incremental knowledge-based system to facilitate learning content adaptation in DLE. To be specific, the knowledge base contains a set of rules incrementally constructed using Ripple Down Rules (RDR) after evaluating a series of test cases. The test cases are generated automatically by analyzing the attributes that reflect the learning situation. Since it is impossible to perform thorough testing involving all input parameters, the selection criteria using pairwise testing are applied to minimize the refinement. Therefore, the evaluation of the theoretical concept is then carried out on a real case. The selected case study for the analysis is the subject of Computer Networking for an undergraduate course. Several adaptive scenarios are presented based on some criteria. An education expert is involved in recommending suitable content for adaptation during the evaluation phase. However, the knowledge base development is automatically constructed from the incremental knowledge acquisition process. As the evaluation progresses, the knowledge base is validated for its accuracy in predicting learning content recommendations.

Authors: Hariyadi Tri , Djali Mohamad , Nurhadi Bambang , Rosniawaty Santi
Published: December 2022

The quality of coffee beans is influenced by the level of maturity, which can be determined based on the skin color of the coffee fruit and post-harvest processing. The study was conducted to determine the effect of freeze-drying on various variations in the level of maturity of water content, caffeine, and heat transfer value. The freeze-drying method was chosen because it can maintain the chemical content of the food. Robusta coffee was obtained from Karawang Regency, West Java, Indonesia. Coffee fruit is sorted by skin color using a colorimeter. Fresh beans are obtained by stripping the fruit skin and epidermis and washing mucus. Fresh bean is reduced in size until it passes the 18-mesh sieve. Freeze-drying is operated at an initial temperature of -20 â„ƒ, sublimation temperature of 40 â„ƒ, and operating pressure of 1 to 6 mbar abs. Water content analysis using gravimetric methods, caffeine content analysis using UV-Vis spectrophotometry method, and fat content using the Soxhlet method. The total heat transfer value is determined from the cup to the material. The results showed that the freeze-drying process at semi-ripe to over-ripe maturity levels could reduce the water content to the permissible limit but cannot be used for unripe. The results of the statistical significance test show that the freeze-drying process at various maturity levels can significantly reduce the water content but can maintain the caffeine content in robusta coffee beans. The highest heat transfer value occurs at the un-ripe maturity level of 86.50 kJoule.
Analysing Kinship in Severe Acute Respiratory Syndrome Coronavirus 2 DNA Sequences Based on Hierarchical and K-Means Clustering Methods Using Multiple Encoding Vector
Authors: Banjarnahor Evander , Bustamam Alhadi , Siswantining Titin , Tampubolon Patuan
Published: December 2022

Based on the World Health Organization data obtained in mid-April 2021, Coronavirus or Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has already infected more than 134.9 million people worldwide. The virus attacks human breathing, which can cause lung infections and even death. More than 2.9 million people worldwide have died due to coronavirus infection. Meanwhile in Indonesia, more than 1.5 million people has been infected and 42.5 thousand people died because of this coronavirus. Based on this data, it is important to carry out a kinship analysis of the coronavirus to reduce its spread. Identification of the kinship of the COVID-19 virus and its spread can be done by forming a phylogenetic tree and clustering. This study uses the Multiple Encoding Vector method in analysing the sequences and Euclidean distance to determine the distance matrix. This research will then use the Hierarchical clustering method to determine the number of initial centroids, which will be used later by the K-Means clustering method kinship in the SARS-CoV-2 DNA sequence. This study took samples of DNA sequences of SARS-CoV-2 from several infected countries. From the simulation results, the ancestors of SARS-CoV-2 came from China. The results of the analysis also show that the closest ancestors of COVID-19 to Indonesia came from India. The SARS-CoV-2 DNA sequence also consisted of nine clusters, and the sixth cluster has the most number of members.

Published: December 2022

Palm oil shell (POS) is a solid waste from the oil palm industry and can cause environmental problems. This waste could convert into high-quality products such as biochar, bio-oil, and biogas that follow reaction mechanisms and kinetics parameters. This study aims to characterize palm oil shells and biochar, determine the optimum temperature of oil palm shell pyrolysis to produce biochar as briquettes and obtain kinetics and thermodynamic parameters. Palm oil shells were cleaned, sifted to a size of 0.4-2 mm, and dried at 105 ÂºC for 24 h. The pyrolysis was operated by 200 g of POS in a pyrolysis reactor and kept at 350 ÂºC, 375 ÂºC, and 400 ÂºC for 1 h. The bio-oil mass was recorded every 5 min, starting from the first drop after the temperature of pyrolysis reached. The optimum temperature for charcoal briquettes was 375 oC. The liquid and solid products were increased by increasing temperature, and gas products were decreased. The kinetics parameters of activation energy (E) and pre-exponential factor (A) were 20.7808 kJ mol-1 and 0.0821 min-1, respectively. Palm oil shell pyrolysis requires a lot of heat which is indicated by a positive enthalpy change (âˆ†H) of 15.3934 kJ mole-1. The non-spontaneous reaction on pyrolysis was proved by a positive Gibbs free energy change (âˆ†G) of 179.2998 kJ mole-1. Those parameters allow the process to be operated in optimal conditions, increasing the efficiency in future studies.
Impact of Feature Selection and Data Augmentation for Pregnancy Risk Detection in Indonesia
Authors: Basuki Setio , Irfan Muhammad , Azhar Yufis
Published: December 2022

This paper aims to develop an automatic system for pregnancy risk detection in Indonesia. The system requires a sophisticated approach to achieve the required performance as a sensitive field. Existing works are developed using small-sized datasets and limited classification features. Moreover, all features treated equally make the detection results hard to interpret which features contribute more. To address these issues, we propose to combine more complex features, data augmentation methods, and feature selection techniques. We prefer to use all 118 pregnancy indicators and 400 instances from Puskesmas as an original dataset. Next, the new datasets are used to build two data augmentation methods, i.e., GMM and CTGAN. Each data augmentation method generates 2,000 new synthetic instances. Following this, five machine learning methods combined with three feature selection approaches, i.e., RFE, Random Forest, and Chi-Square, are implemented in all datasets. Through experiments, we observed that feature selection techniques play an essential role in improving classification accuracies. While the GMM-based augmentation demonstrated performance improvement, the CTGAN-based synthetic dataset depicted low performances. The best accuracy on all experiment settings reached 95%. By using Random Forest combined with RFE on a GMM-based dataset, the highest accuracy was achieved using only five features. Another notable result is that both XGBoost and Decision Tree reached the same 95% accuracy on the GMM-based dataset on only nine features. The overall results show that appropriate data augmentation and feature selection are a matter for achieving better performance in this research.
Tonne Kilometre Per Hour (TKPH) Prediction for Lifetime Tire Estimate Using Statistical Analysis: A Case Study at Coal Mine
Authors: Sari Laura Puspita , Seto Franklin Chandra Pragnyono
Published: December 2022

To expedite mining production activities, the condition of the transportation equipment of fuel and spare parts must be ready because the loss of time due to refueling and waiting for spare parts can reduce the Physical Availability value of the dump truck. In this study, the type of tire used as the research object is a tire measuring 33.00-51. The initial identification of tire conditions showed that the Hours meter average was smaller than the Key Performance Indicator (KPI) Hours meter, which was 2719 HM. The type of tire damage that dominates is Sidewall Separation, with a damage percentage of 54%. This study aims to predict the value of TKPH with ten independent variables that exist in the activity of the transportation cycle. The method used to predict is the Multiple Regression and ARIMA statistical methods. From the results of Multiple Regression using the SPSS application, three models are produced, each with different independent variables. As for ARIMA seen from the choleogram of the Autocorrelation Function (ACF) and Partial Autocorrelation Function (PACF), the number of lags = 1, so ARIMA models that can be applied may be (1,0,1) and (1,1,0). The results of the study prove that the prediction model that is close to this is the Multiple Regression Model 3 where the Mean Absolute Deviation (MAD) value is 69.16, the Mean Absolute Prediction Error (MAPE) is 66.07, and the R-square value is 52.41%.
Flood Vulnerability Evaluation and Prediction Using Multi-temporal Data: A Case in Tangerang, Indonesia

Published: December 2022

Land-use change has an impact on growing physical flood vulnerability. Geographic Information System (GIS) and Analytic Hierarchy Process (AHP) approaches are increasingly being used for flood vulnerability assessments. However, none has used time-series land cover data for evaluation and rainfall over various return periods for prediction simultaneously, especially in Indonesia. Therefore, this study aims to evaluate and predict physical flood vulnerability using time-series land cover data and rainfall data over various return periods. Eight criteria were considered in the assessment: elevation, topographic wetness index, slope, distance to the river, distance downstream, soil type, rainfall, and land cover. The criteria weights were determined using the AHP method based on expert judgment. The multi-criteria model was built and validated using flood inundation data. Based on the validated model, the effect of land cover changes on flood vulnerability was evaluated. The flood vulnerability changes were also predicted based on rainfall over various return periods. The evaluation and prediction models have shown reliable findings. The criterion elevation and distance to the river significantly influenced the physical flood vulnerability by 41% and 20%. The evaluation model showed a strong correlation between the built-up area and the area with high flood vulnerability (r2 = 0.96). Furthermore, the model predicted an inundation area expansion for rainfall over various return periods. Further research using spatial data with higher resolution and more advanced validation techniques is needed to improve the model accuracy.
Native Bacillus subtilis Strains Efficiently Control Lupin Anthracnose Both under Greenhouse and in Field Conditions

Published: December 2022

Colletotrichum acutatum is the cause of lupin anthracnose in the Andean zone. The pathogen affects the crop throughout its entire production cycle, causing losses of up to 100%. In previous studies, native strains of B. subtilis (CtpxS1-1; CtpxS2-1 and CtpxZ3) from the province of Cotopaxi reduced anthracnose infections in seed and seedlings. This study evaluated the potential biological control of these strains by using two lupin anthracnose susceptible cultivars under greenhouse conditions and in the field. Plants of I-451 GÃ¼aranguito and I-450 Andino cultivars were treated with active biomass from each B. subtilis strain.

O mercado de polpas de frutas congeladas é uma excelente alternativa para evitar desperdícios e perdas, agregando valor econômico à fruta e tornando-se promissor ao setor alimentício, possibilitando o uso de diferentes sabores de polpas de frutas, independente da sazonalidade. A produção artesanal de polpas de frutas é uma atividade comum na cidade de Porto Franco-MA. Assim, o presente trabalho objetivou avaliar características físico-químicas e microbiológicas de polpas de acerola e cajá produzidas artesanalmente, verificando se estas se adequam aos padrões de qualidade da legislação vigente. Para tanto, foram utilizadas 6 amostras, onde foram realizadas análises de pH, sólidos solúveis (°Brix), acidez total titulável (AT) e vitamina C (ácido ascórbico), e também análises microbiológicas de coliformes a 45°C, Salmonella sp., bolores e leveduras e bactérias aeróbias mesófilas. Dos resultados obtidos, todas as polpas encontraram-se dentro dos Padrões de Identidade e Qualidade (PIQ) quanto a pH e sólidos solúveis. Entretanto, as polpas de acerola encontraram-se abaixo do limite mínimo estabelecido pela legislação para acidez titulável (0,8%) e vitamina C (800 mg/100g). Quanto as análises microbiológicas, todas as polpas apresentaram ausência de Salmonella sp., e coliformes a 45°C <3, atendendo aos padrões exigidos pela legislação, assim como bolores e leveduras e bactérias aeróbias mesófilas. Portanto, as polpas de cajá foram que melhor atenderam aos padrões da legislação, porém, as inconformidades nas polpas de acerola não afetaram a qualidade microbiológica das polpas, pois todas a amostras estavam de acordo com a legislação em vigor.

Capital providers, such as shareholders on capital markets or European funding providers, are interested in the net present value of discounted cash flow and the risks or opportunities that may contribute to financial planning in a negative or positive way. Since the Sarbanes Oxley act, corporations listed on US capital markets are demanded to practice enterprise risk management. There are several methodologies in place: the COSO framework, ISO 31 0000, RIMs Risk Maturity. These are holistic approaches to risk management in all business aspects, with a designated methodology. This methodology will be the scholarly literature review in this article, whose goal to elaborate the reference enterprise risk management methodologies and their relevance in empirical data analysis, European project funding calls. European projects demand risk management and mitigation, but do not offer a reference framework to do this. The article purposes to make European funds easy to understand as their requirements are explained and the most suitable scientific solution is sought. The methodology is a descriptive case study, with instrumental value. Findings are that funding authorities, be they capital markets or public funds, benefit highly in their decisions by the integration of opportunities and risks. The research concerns the suitability of enterprise risk management with European funds, and the conclusion of a perfect match confirms theory, brings it new scope, and may be of high practical use as for the coherent and timely documentation of European project funding calls.
Effectiveness of corporate mergers and acquisitions in developed and emerging countries
Authors: Kucharski Adam , Marszałek Jakub
Published: December 2022

The aim of the article is to compare the effects of mergers and acquisitions carried out by entities from developed and emerging countries. The article covers consolidation transactions completed between 2000 and 2018, exclusively by listed automotive companies. 764 consolidation transactions extracted from the Thomson Reuters Eikon database were observed, for which an efficiency measurement method based on the relationship of the share price to the stock market index was adopted. Data analysis was carried out using descriptive statistics and statistical inference methods. A comparison of the efficiency of M&As completed in developed and emerging countries showed no significant differences in a statistical sense. This means that the macroeconomic conditions of the country from which the company originates have no significant impact on the chances of success of the consolidation implemented by the company. Companies from emerging countries were found to be more profitable, with higher liquidity and were less indebted. On the other hand, entities from developed countries had better operating efficiency ratios, suggesting that they achieved higher margins. The study thus also contradicts the thesis that cost position is important for the efficiency of entities, especially in emerging countries. In the context of the results of the comparison between the two groups of companies, it is reasonable to assume that the determinants of consolidation success are microeconomic in nature and are independent of the country in which the transaction takes place.
