Published: June 2024

The aim of this study is to present the research scenario involving MOOCS, a new learning format that has the potential to become a disruptive innovation when compared to traditional teaching-learning models. Descriptive and quantitative work, bibliometric in nature, seeks to raise the characteristics of academic production. For that, a bibliometric search was carried out in the Web of Science database, in which 2,079 articles published in the period from 2011 to 2020 were investigated, in the respective database, including the characterization of production, methodological aspects and related themes. Initially, the total number of publications was identified, characterized by their thematic areas, types of documents, year of publication, authors, funding agencies and institutions, countries and languages. The research was carried out using Excel tools and VOSViewer software. It is also observed that the degree of cooperation between the authors is significant. Among those that stand out more are Kloos C.D. and Hoyos A.C. It can be seen that the main authors in the area are Spanish, despite the fact that this education model emerged in the United States in 2008.

Authors: Setyawan Herlin , Sukardi Sukardi , Risfendra Risfendra , Putri Meri Yulianti , Oktavia Vivi , Ambiyar Ambiyar , Wulansari Rizky Ema
Published: June 2024

The problem in this study is that many students in the electrical power installation engineering (EPIE) class have not mastered the skills of electric motor control (EMC). This is because the teacher still uses traditional methods in the learning process. Namely, the teacher actively explains the material according to practical experience rather than referring to EMC learning objectives. This study aims to apply a variable speed drive (VSD) jobsheet based on project-based learning (PjBL) in the EMC learning process and measure the effectiveness of the jobsheet applied. The research method used was a pre-experiment with an intact group comparison research design. The research subjects were taken from 11th-grade students of vocational schools majoring in electrical power installation engineering and were assessed using a questionnaire instrument to evaluate students' EMC performance. Data analysis techniques used were independent t-test and effect size test. Based on the independent t-test analysis results, the t-value is larger than the t-table (t = 4.936 > 1.99962), and the significance value is 0.000, which shows a significant difference in skills between the experimental and control classes. Based on the effect size analysis, the value is 1.243, which means the jobsheet can improve students' EMC skills in the large category. Based on these two results, it is known that the PjBL-based VSD jobsheet is effective in the EMC learning process. Thus, it is expected that EPIE vocational high schools can use the PjBL-based VSD Jobsheet in the EMC learning process.

Wide application in the oil and gas industry made carbon steel suffer annual losses due to corrosion. The corrosion protection utilizes inhibitor have drawbacks expensive and harmful to the environment. Potato peel extract (solanum tuberosum L) and its main constituents, such as flavonoids, alkaloids, and tannins, have been investigated as a green corrosion inhibitor for low-carbon steel in a 3.5% NaCl solution. The inhibitor’s effectiveness and corrosion rate monitoring were measured using weight loss. Potentiodynamic polarization was used to investigate the type of corrosion inhibition and adsorption of plant extract on the surface. Fourier transform infrared spectroscopy (FTIR) was utilized to observe the presence of functional groups, natural compounds, and the type of bonding for adsorbed organic inhibitors on the surface. The results of the Tafel polarization analysis indicated that the potato peel extract acts as a mixed-type inhibitor. The inhibition efficiency increased with the concentration of the inhibitor extract. The optimal inhibition efficiency of 73.33% is was achieved with 6 ml of potato peel extract and 216 hours of immersion time. The inhibitive effect is due to the adsorption of inhibitor molecules on the steel surface, following the Langmuir adsorption isotherm.

Published: June 2024

The waste collection stage generated 70% of the cost of the total Municipal Solid Waste (MSW) management system. Therefore, choosing the most affordable waste collection method is essential to accurately estimate the waste collection and transportation costs, thus selecting the required vehicle capacity. The study aims to design a waste collection system for calculating waste collection and transportation costs using a systematic framework that includes Hybridized Ant Colony Optimization (HACO) with Sequential Variable Neighborhood Search Change Step (SVNSCS) and Sequential Variable Neighborhood Decent (SVND). The framework addresses a Dynamic Capacity of Vehicle Routing Problem (DCVRP) and improves ACO's ability in exploration and exploitation stages. The objectives are to minimize the cost of travel distance and arrival time formulated in a mathematical model and to design a new strategy for eliminating the sub-tour problem in the following steps: (1) minimize the number of routes assigned, (2) increase the amount of waste in the vehicle capacity, and (3) define the best amount of waste allowed in vehicle capacity. The waste collection system compared HACO with ACO across four benchmark datasets. The results indicate HACO outperformance ACO at 100%, 91%, 100%, and 87%, respectively. The visualization results demonstrated that HACO has fast convergence and can be considered another essential tool for route optimization in the waste collection system.
Стационарное осесимметричное пространство-время с нарушенной $P$-четностью, допускающее главную конгруэнцию
Authors: Туракулов Зафар
Published: June 2024

Явление нарушения пространственной четности или $P$-четности, как его называют в физике элементарных частиц, рассмотрено как чисто геометрическое и выражающее свойства пространства-времени. Определение этого свойства возможно при условии, что пространствство-время обладает по крайней мере вращательной симметрией. При этом условии удается определить аналог зеркального отражения как дискретной операции симметрии. Применяя эти определения, все модели пространства-времени, построенные в общей теории относительности, можно разделить на четные и нечетные по отношению к этому преобразованию симметрии. Показана связь нечетности пространства-времени с кротовыми норами и гравимагнитным зарядом.

Finding matches between puzzle pieces is a difficult problem relevant to applications that involve restoring broken objects. The main difficulty comes from the similarity of the puzzle pieces and the very small difference between a pair of pieces that almost match and one that does. The proposed solution is based on deep learning models and has two steps: firstly, the pieces are segmented from images with a U-Net model; then, matches are found with a Siamese Neural Network. To reach our goal, we created our own dataset, containing 462 images and just as many masks. With these masks, we built 3318 pairs of images, half of them representing pieces that fit together and half that do not. Our most relevant result is estimating correctly for 290 out of 332 pairs whether they match.

Considering the current advancements in computer vision it can be observed that most of it is focused on two-dimensional imagery. This includes problems such as classification, regression, and the lesser-known object matching problem. While object matching ca be viewed as a solved problem in a two-dimensional space, for a three-dimensional space there is a long way to go, especially for non-rigid objects. The problem is focused on matching a given object to a target object. We propose a solution based on Graph Neural Networks that tries to generalize over multiple objects at once, based on self-attention and cross-attention blocks for the network. To test our solution, we utilised five convolutional operators for the layers of the model. The convolutional operators we compared included GCNConv, ChebConv, SAGEConv, TAGConv, and FeaStConv. This paper aims to find the best operators for our architecture and the task. Our approach obtained favourable results for predicting the barycentric weights for the model, while struggling to predict the triangle indexes. The best results were obtained for the models using GCNConv, for the triangles index prediction and FeaStConv for the barycentric coordinates prediction.

Dinámica demográfica, forma urbana y densidad de población en ciudades de México, 1990-2020: ¿urbanización compacta o dispersa?
Authors: Sobrino Figueroa Luis Jaime
Published: June 2024

El propósito de este artículo consiste en ofrecer evidencia empírica sobre las características de la dinámica demográfica y de la expansión física del desarrollo urbano en México entre 1990 y 2020, con el fin de identificar patrones de forma urbana y de contribuir al debate sobre la configuración compacta o dispersa del crecimiento. La pregunta general es si la urbanización contemporánea en México ha sido compacta o dispersa. Para lograr dicho propósito y contestar el cuestionamiento, se utiliza información estadística y cartográfica de los censos de población y vivienda. La conclusión general es que en México coexisten ciudades compactas y ciudades dispersas. En el marco de un descenso en la dinámica demográfica del país, la participación de la población que reside en asentamientos discontinuos se incrementó de manera discreta, indicador de la urbanización dispersa, además de que la densidad de población aumentó marginalmente, indicador de la urbanización compacta. Estos resultados matizan el patrón concentrado o disperso de la urbanización en México. La organización intraurbana e intrametropolitana de la población ha estado estrechamente relacionada con las modalidades del mercado urbano de vivienda y ha tenido efecto en el funcionamiento de los mercados urbanos de trabajo y de transporte.
Preparation and Study of Structural, Optical and Electrical Properties of the Composite Films [PVA-PEO-MnCl2.4H2O]
Authors: Hameed Alaa , Sabah A. Salman
Published: June 2024

In the present paper, pure polymeric blend film [PVA-PEO] and the polymeric blend films reinforced by MnCl2.4H2O  salt with different weight ratios (10, 20, 30, 40, 50 wt %) have been prepared  by using the solution casting method. The effects of weight ratio of salt on structural properties for all reinforced polymeric blends  films were studied.  FTIR spectra were used to establish  the interaction between the polymer (PVA) and the polymer (PEO) reinforced by MnCl2.4H2O salt, which causes some changes in the vibration modes and the position of the bonds. All inrestigated  samples exhibited  broad  bonds at  around  (3310 cm-1). The results showed the asymmetric vibration of  O-H group in the polymers matrix.  The peaks around (2880 cm-1) can be attributed to the presence of C- H stretching vibration group. The C=C stretching vibration appears in the bonds at (1955 cm-1). The peak at (1096 cm-1) for all reinforced films is attributed to the stretching mode of C-O-C stretching. There is a shift of out-of-plane rings C-H bending vibration from 961.2 to 955 cm-1. These indicate the chemical interactions of MnCl2.4H2O salt with the polymeric blend [PVA-PEO]. The two strong bonds observed around (1471 cm-1 and 844 cm-1) are assigned to the bending and stretching vibration of the CH2 group, respectively. The change in the spectral intensities of polymeric blend [PVA-PEO] involves a shift in some bonds due to the MnCl2.4H2O salt  addition.   The effects of weight ratio of salt  on optical properties for all reinforced polymeric blends films  were studied,  as the transmittance and absorbance  spectra  were  recorded within the range of wavelengths (190-1100) nm, and it was found that the energy gap value decreases with an increase of the  added  salt’s weight ratio. Results showed that the indirect electronic transitions are allowed.  Effects of salt’s weight ratio on electrical (dielectrical) properties for all reinforced polymeric blends films  were studied,  and the practical results showed a decrease in the dielectric constant (ε΄) with an increase in frequency for all polymeric blends films, while the practical results also showed an increase in the alternating electrical conductivity (σa.c)  with increasing frequency for all polymeric blends films, as well as an increase in both the dielectric constant and  alternating electrical conductivity with an increase in the added  salt’s weight ratio at same frequency.

Published: June 2024

The scarcity of the insulators that are required for refrigeration has made it necessary to use locally available materials that can achieve the desired refrigeration. This work presents the performance evaluation of a refrigerator utilizing a locally available material, which is wood particles that have been converted to particle board, as one of its insulators. A vapor compression refrigeration system was designed and fabricated to chill and preserve agricultural products, which are eggs, yogurt, and tomatoes. The various temperatures at which the agricultural products became chilled were compared with their theoretical preservation temperatures obtainable in literature, thereby evaluating the performance of the refrigerator. The temperature of 11 ℃, which was recorded for the egg in the present experiment, is lower than the theoretical preservation temperatures of 18 ℃ to 21 ℃ for an egg. The temperature of 7 ℃, which was recorded for the yogurt, is approximately equal to its theoretical preservation temperature of 5 ℃. The temperature of 8 ℃, which was recorded for the tomato, is lower than the theoretical preservation temperatures of 7 ℃ to 10 ℃ of tomato. This work has revealed that wood particles have the potential to achieve refrigeration, as well as chill and preserve agricultural products.
Decarbonization of Production Systems in Foundries
Authors: Kolmasiak C.
Published: June 2024

The article discusses the growing importance of decarbonization of production systems in the foundry industry as a response to climate challenges and increasing requirements for sustainable development. The process of reducing greenhouse gas emissions in foundry production is caused by a number of reasons. Decarbonization of the foundry industry refers to actions aimed at reducing greenhouse gas emissions, especially carbon dioxide (CO2). Reducing carbon dioxide emissions is increasingly being considered as a key element of the strategy of both small and large foundries around the world. Foundry is one of the industries that generates significant amounts of carbon dioxide emissions due to the energy consumption in the process of melting and forming metals. There is virtually no manufacturing industry that does not use elements cast from iron, steel or non-ferrous metals, ranging from elements made of aluminum to zinc. The article presents various decarbonization strategies available to foundries, such as: the use of renewable energy, the use of more efficient melting technologies, or the implementation of low-energy technologies throughout the production process. Application examples from different parts of the world illustrate how these strategies are already being put into practice, as well as the potential obstacles and challenges to full decarbonization.
Analysis of Fragmentation Phenomenon of Composite Layers of Fe-TiC Type Obtained “in situ” in Steel Casting
Authors: Marosz J. , Sobula S.
Published: June 2024

A method for fabrication of a composite layer on the surface of a steel casting using coating containing TiC substrates was presented. The reaction of the synthesis of the ceramic phase was based on the SHS method (Self-propagating High-temperature Synthesis) and was triggered by the heat of molten steel. High hardness titanium carbide ceramic phases were obtained, which strengthened the base material improving its performance properties presented in this article. Microstructural examinations carried out by light microscopy (LM) on the in-situ produced composite layers showed that the layers were the products of reaction of the TiC synthesis – the phenomenon called “fragmentation” by the authors of study. The examinations carried out by scanning electron microscopy (SEM) have revealed the presence of spheroidal precipitated and free of impurities. The presence of titanium carbide was twofold increase in hardness in the area of the composite layer as compared to the base alloy which was carbon cast steel.
The (Mal)Functionality of Vernacular
Authors: Bronner Simon J.
Published: June 2024

Continuing a dialogue with Ülo Valk on the value of the etic term vernacular in folk-loristic scholarship, this essay responds to his claim that despite the stigma of the word’s past usage and its rejection by other fields it holds promise for folkloristics because of its conceptual flexibility, which he finds is especially conducive to the study of belief and religious practices. Pointing out that flexibility – or “fuzziness” to quote other critics – suggests imprecision, residualism, hierarchy, and lack of analytical instrumentality, this essay contends that use of vernacular reveals more about its users than the groups and practices it purports to describe. Recounting the intellectual history of the term and its adoption in folkloristic circles as well as the author’s own scholarship, this essay maintains that the term has limited, if any, use in folkloristics and ethnology because of its negative assumptions and “fuzzy” logic. It can be reflexively analyzed, however, to understand scholars’ perceptions of cultural phenomena and their conflicts with cognitive categories of practice and belief enacted by cultural participants.

Published: June 2024

Gesture recognition is a crucial aspect in the advancement of virtual reality, healthcare, and human-computer interaction, and requires innovative methodologies to meet the increasing demands for precision. This paper presents a novel approach that combines Impedance Signal Spectrum Analysis (ISSA) with machine learning to improve gesture recognition precision. A diverse dataset that included participants from various demographic backgrounds (five individuals) who were each executing a range of predefined gestures. The predefined gestures were designed to encompass a broad spectrum of hand movements, including intricate and subtle variations, to challenge the robustness of the proposed methodology. The machine learning model using the K-Nearest Neighbors (KNN), Gradient Boosting Machine (GBM), Naive Bayes (NB), Logistic Regression (LR), Random Forest (RF), and Support Vector Machine (SVM) algorithms demonstrated notable precision in performance evaluations. The individual accuracy values for each algorithm are as follows: KNN, 86%; GBM, 86%; NB, 84%; LR, 89%; RF, 87%; and SVM, 87%.

Background

Patients with familial adenomatous polyposis (FAP) develop early colorectal adenomas and if left untreated, progression to cancer is an inevitable event. Prophylactic surgery does not prevent further development of cancer in the rectal remnant, rectal cuff in patients with ileal pouch anal anastomosis (IPAA) and even on the ileal mucosa of the pouch body. The aim of this review is to assess long-term rates of cancer and adenoma development in patients with FAP after prophylactic surgery and to summarise current recommendations for endoscopic management and surveillance of these patients.

Materials and methods

A systematic literature search of studies from January 1946 through to June 2023 was conducted using the PRISMA checklist. The electronic database PubMed was searched.

Results

Fifty-four papers involving 5010 patients were reviewed. Cancer rate in the rectal remnant was 8.8–16.7% in the western population and 37% in the eastern population. The cumulative risk of cancer 30 years after surgery was 24%. Mortality due to cancer in the rectal remnant is 1.1–11.1% with a 5-year survival rate of 55%. The adenoma rate after primary IPAA was 9.4–85% with a cumulative risk of 85% 20 years after surgery and a cumulative risk of 12% for advanced adenomas 10 years after surgery. Cumulative risk for adenomas after ileorectal anastomosis (IRA) was 85% after 5 and 100% after 10 years. Adenomas developed more frequently after stapled (33.9–57%) compared to hand-sewn (0–33%) anastomosis. We identified reports of 45 cancers in patients after IPAA of which 30 were in the pouch body and 15 in the rectal cuff or at the anastomosis.

Conclusions

There was a significant incidence of cancer and adenomas in the rectal remnant and ileal pouch of FAP patients during the long-term follow-up. Regular endoscopic surveillance is recommended, not only in IRA patients, but also in pouch patients after proctocolectomy.

Background

Recent evidence brought by novel anti-human epidermal growth factor receptor 2 (HER2) antibody-drug conjugates is leading to significant changes in HER2-negative breast cancer (BC) best practices. A new targetable category termed ‘HER2-low’ has been identified in tumors previously classified as ‘HER2-negative’. Daily practice in pathology and medical oncology is expected to align to current recommendations, but patient access to novel anticancer drugs across geographies might be impeded due to local challenges.

Materials and methods

An expert meeting involving ten regional pathology and oncology opinion leaders experienced in BC management in four Central and Eastern Europe (CEE) countries (Bulgaria, Croatia, Serbia, Slovenia) was held. Herein we summarized the current situation of HER2-low metastatic BC (mBC), local challenges, and action plans to prevent delays in patient access to testing and treatment based on expert opinion.

Results

Gaps and differences at multiple levels were identified across the four countries. These included variability in the local HER2-low epidemiology data, certification of pathology laboratories and quality control, and reimbursement conditions of testing and anticancer drugs for HER2-negative mBC. While clinical decisions were aligned to international guidelines in use, optimal access to testing and innovative treatment was restricted due to significant delays in reimbursement or limitative reimbursement conditions.

Conclusions

Preventing delays in HER2-low mBC patient access to diagnosis and novel treatments is crucial to optimize outcomes. Multidisciplinary joint efforts and pro-active discussions between clinicians and decision makers are needed to improve care of HER2-low mBC patients in CEE countries.
Post-Modern Planning Theory: the New era of Indonesia Energy Planning
Authors: Amelia Syarifah , Pradono Pradono , Rahayu Harkunti Pertiwi , Kombaitan Benedictus
Published: June 2024

Objective: The objective of this study is to explore how decision-making procedures based on postmodern planning theories can facilitate the integration of social and environmental aspects into energy planning. This is critical in the context of global agendas such as the Sustainable Development Goals (SDGs) and the New Urban Agenda (NUA), which emphasize the provision of clean energy and equitable access to energy.
 
Theoretical Framework: This study is grounded in postmodern planning theories, which prioritize inclusivity, communication, and the negotiation of values among various stakeholders. These theories contrast with traditional, market-oriented energy planning approaches that often marginalize social and environmental considerations.
 
Method: The research employs a qualitative approach, analyzing case studies where postmodern planning principles have been applied to energy planning. This includes a review of policy documents, interviews with key stakeholders, and an examination of the interactions between government sectors and between the government and society.
 
Result and Discussion: The findings indicate that postmodern planning approaches can effectively bridge the gap between social/environmental goals and economic interests in energy planning. Through enhanced communication and negotiation among stakeholders, it is possible to achieve more inclusive and sustainable energy policies. The study highlights specific instances where these approaches have led to more balanced energy planning outcomes, especially in regions focused on rapid economic growth.
 
Research Implication: The implications of this research suggest that adopting postmodern planning principles can significantly improve the inclusivity and sustainability of energy planning processes. Policymakers are encouraged to foster greater communication and value exchange among stakeholders to balance economic, social, and environmental objectives.
 
Originality/Value: This study contributes to the literature by demonstrating the practical application of postmodern planning theories to energy planning. It provides a novel perspective on how to reconcile the often competing interests of economic growth and sustainable development, particularly in the energy sector.

Catedráticos de Enseñanza Secundaria: ¿un cuerpo en extinción?
Authors: Galicia Mangas Francisco Javier
Published: June 2024

Objetivos: verificar si el Cuerpo de Catedráticos de Enseñanza Secundaria se halla o no en peligro de extinción, a consecuencia de la falta de convocatoria de nuevas plazas para la promoción profesional del profesorado de Enseñanza Secundaria. Metodología: la propia de las ciencias sociales y jurídicas, que parte del estudio histórico legislativo de la institución, para llegar a la normativa vigente. Se incorporan los datos recientes obtenidos de las diferentes comunidades autónomas y del Ministerio de Educación y Formación Profesional, a través de los cauces legales de acceso a la información pública. Resultados: se observa una disminución muy relevante del número de catedráticos de Enseñanza Secundaria, desde la atribución de competencias en materia de educación a las comunidades autónomas. Conclusiones: el acceso a los cuerpos de catedráticos forma parte del derecho a la promoción profesional de los funcionarios docentes. El sistema actual de acceso es el de concurso de méritos. Las funciones atribuidas a los catedráticos incluyen la docencia, proyectos de innovación e investigación, y la dirección y coordinación didáctica. Cada vez hay un menor número de catedráticos de Enseñanza Secundaria debido a la ausencia de convocatorias por parte de las Administraciones educativas.
Defensa de derechos laborales y profesionales en el magisterio veracruzano
Authors: Pedroza Cervantes José Manuel , Tirado Villegas Gloria A. , Sáez Díaz Diana Karent
Published: June 2024

Desde la perspectiva de género y la historia de la educación, este trabajo dilucida las trayectorias profesionales de las maestras Petra Calatayud y Felipa Flores, mujeres veracruzanas que vivieron en la bisagra del siglo XIX y XX, y de quienes la historia oficial había soterrado quehaceres en la vida pública: sus luchas, sus logros y fracasos. Seguir las pistas de las normalistas permite conocer cómo influyeron en ellas la ciencia y la pedagogía moderna en cuanto a saberes, actitudes y valores. Se hace notar algunas dificultades que vivieron y a las cuales hicieron frente, así como los procesos que trasgredieron a lo largo de sus carreras profesionales. Como se analiza en el texto, no sabemos si fueron feministas, lo que sí [re]conocemos es que lucharon por sus derechos laborales, alzaron la voz contra las estructuras dominantes y exigieron mejores condiciones para ellas y para su género.

Interpretative conflicts in the Colombian judicial system
Authors: López Daza Germán Alfonso
Published: June 2024

The debate on interpretative conflicts in constitutional matters is a subject of continuous relevance, not only in Colombia but also in countries where there is a constitutional justice system that is strongly active in the protection of fundamental rights and in the defense of the constitution. The power to create law through the interpretation made by constitutional judges in very specific problems is a very complex issue since it involves applying constitutional regulations to cases, seeking the integration that will allow them to find the solution to the issue in question. This article, product of jurisprudential research, addresses the problem of judicial interpretation, specifying it in terms of interpretative divergences of the high Courts in Colombia, which has implied the reconfiguration of the classic scheme of the balance of powers and consequently the existence of conflicts between the powers.
