Authors: Mazhar Bal
Published: April 2024

The aim of this study is to examine the precautions and policies of the Ministry of National Education (MoNE) in the preearthquake period for disadvantaged groups that may be affected by earthquakes. One out of five students in Turkey
was affected by the February 6, 2023, earthquake in the country. In terms of the education system, the earthquake
caused psychological problems, difficulty accessing education, and economic issues. MoNE has not provided inclusive
training for teachers for the education of children directly affected by earthquakes in the last five years. There is a teacher
module for inclusive education for children affected by disasters, but there is no educational content for students directly
affected by the earthquake.
Development and validation of Emotional Competence Scale (ECS) for upper primary school students
Authors: Nikita Yadav , Rajkumari Singh
Published: April 2024

This paper is an attempt to develop and validate the Emotional Competence Scale (ECS) in order to assess the emotional
competence of upper primary school students. This review was done to find the dimensions that measure emotional
competence. The dimensions are classified into two broad categories, such as personal competence and social
competence. Personal competence includes self-awareness, emotional awareness, emotional regulation, responsible
decision-making, and trust in expressivity. Social competence includes social awareness, social skills, and relationship
management. The ECS was constructed to measure emotional competence across personal and social dimensions.
The scale underwent rigorous development stages, including item collection, expert validation, piloting, item analysis,
and refinement. The final ECS comprised 14 items with a five-point Likert scale for responses. Reliability analysis using
Cronbach's alpha and split-half reliability demonstrated high internal consistency (α = 0.70, split-half reliability = 0.77).
Face and content validity were established through expert evaluations, confirming the scale's appropriateness for
measuring emotional competence in upper primary school students.
Creative teaching: A conceptual framework
Authors: Flavia P D'souza , Padmanabha C. H.
Published: April 2024

Human beings are born creative, however, as they grow and interact with society, they often become less creative or are
taught to be uncreative. Children are naturally full of curiosity and creativity; they perceive their surroundings in unique
ways. However, the environments in which they grow up often stifle their creativity. In modern society, it is crucial to employ
creative teaching methods to bring out the best in students and foster their creativity. Creative teaching also serves to
increase students' interest in the subject matter. According to the National Advisory Committee on Creative and Cultural
Education, the primary task in teaching creativity is "to encourage young people to believe in their creative potential,
engage their sense of possibility, and instill the confidence to try." Creativity in teaching plays a vital role in enhancing
students' learning experiences. Research in educational contexts suggests that confidence, enthusiasm, and
commitment are common qualities found in creative teachers. This article explains how creative teaching develops
creativity and increases interest among students in learning, the barriers to creative teaching in the classroom and
concludes with recommendations to develop creativity in teachers.
Telecommunications, Universal Service and Poverty in Mexico: a Public Policy Assessment (1990–2008)
Authors: Casanueva-Reguar Cristina , Pita S. Antonio
Published: April 2024

This article analyzes the design and implementation of telecommunications service policies targeted at the poorest regions of Mexico (1990–2008). It begins by defining universal access and service policies, their economic and social rationale. Secondly, it discusses the scope of public policies on universal service provision designed by Mexican authorities to achieve the goal of universal access. Thirdly, the paper analyzes the distributive effects of this set of policies among thepoorest sectors of the population. The sources on which this research was based were two national surveys: the Household Income and Expenditure Survey (2008), and the Household Survey of the Access and Use of Information Technologies (2007). The additional information on regional economic development was based on the poverty indexes by the national population council and economic information given by Mexico’s Census Bureau. Additional use was made of the annual reports prepared by Ministry of Communications, statistics published by the Federal Telecommunications Commission and official documents prepared by the government agencies. Finally, a series of in-depth interviews was conducted with the former representatives of the Office of Rural Telephony. Finally, the article discusses, in the light of available evidence, possible explanations for the apparent failure of the universal service policy that was implemented to bring at least basic voice services to Mexico’s neediest.

Published: April 2024

This paper studies a vital issue in wireless communications, which is the transmission of images over wireless networks. IEEE ZigBee 802.15.4 is a short-range communication standard that could be used for small distance multimedia transmissions. In fact, the ZigBee network is a wireless personal area network (WPAN), which needs a strong interleaving mechanism for protection against error bursts. Thispaper presents a novel chaotic interleaving scheme for this purpose. This scheme depends on the chaotic Baker map. A comparison study between the proposed chaotic interleaving scheme and the traditional block and convolutional interleaving schemes for image transmission over a correlated fading channel is presented. The simulation results show the superiority of the proposed chaotic interleaving scheme over the traditional schemes.

Self-Adaptive Stable Mutation Based on Discrete Spectral Measure for Evolutionary Algorithms
Authors: Obuchowicz Andrzej , Pre ̧tki Przemysław
Published: April 2024

In this paper, the concept of a multidimensional discrete spectral measure is introduced in the context of its application to the real-valued evolutionary algorithms. The notion of a discrete spectral measure makes it possible to uniquely define a class of multivariate heavy-tailed distributions, that have recently received substantial attention of the evolutionary optimization community. In particular, an adaptation procedure known from the distribution estimation algorithms (EDAs) is considered and the resulting estimated distribution is compared with the optimally selected referential distribution.
Topological Synthesis of Tree Shaped Structures Based on a Building Blocks Hypothesis
Authors: Miazga Przemysław
Published: April 2024

In this paper a new approach to evolutionary controlled creation of electronic circuit connection topology is proposed. Microwave circuits consisting of a tree like connection of ideal transmission lines are considered. Assuming that a reasonable number of transmission lines in a tree network ranges from 10 to 100, the number of connection combinations is immense. From the engineering practice comes the hypothesis that any device can be decomposed into some functional building blocks consisting of one to dozen transmission lines. The variety of linking combinations in a tree with a limited depth is confined to hundreds or thousands of shapes. Therefore we can decrease the dimensionality of research space, applying evolution to building blocks only. Evolutionary algorithm (EA) which processes simultaneously the population of λ functional blocks and population of μ circuits is proposed. A μ, λ selection scheme with tournament together with specific encoding of solutions, and custom operators is implemented. The μ, λ, α EA was tested on an example of the design of a microwave transistor matching circuit.

Authors: Luo Jie , Liu Yang , Wang Bing , Li Lei , Yang Junyu
Published: April 2024

Objective: To analyze the enduring rotational steadiness of AcrySof IQ Toric intraocular lens (IOL) in cataract patients suffering from myopia in a long-term study. Methods: A retrospective study was conducted on a case series involving 78 patients. A total of 120 eyes with an axial length (AL) ranging from 24–30 mm and corneal astigmatism ≥ 1.50 D underwent implantation of AcrySof IQ Toric IOL guided by the version navigation system. The eyes were divided into two groups based on AL. Group A included 60 eyes with high myopia (AL ≥ 26 mm), while Group B consisted of eyes with low to moderate myopia (24 mm ≤ AL < 26 mm). Data on the preoperative AL were collected. Measurements were taken for residual astigmatism, the best corrected visual acuity (BCDVA), corneal astigmatism, and IOL rotation occurring between 24- and 48-months post-surgery. The percentage of eyes with an IOL rotation of under 5° and 10° was analyzed. Results: The mean length of follow-up times was recorded as 34.27 ± 4.98, and the average rotation was 2.73 ± 1.29°. Group A exhibited a slightly higher average rotation of 2.87 ± 1.31°, compared to the rotation of 2.59 ± 1.27° observed in Group B. At both the 24–36 month and 26–48 month post-operation marks, the degree of IOL rotation did not show a statistically significant difference between the two groups, with none of the patients experiencing a rotation exceeding 10° (P > 0.05). The percentage of rotation degrees under 5° was recorded as 98.22%. After the procedure, the BCDVA was 0.13 ± 0.03 LogMAR. There was a substantial increase in the χ2 value after the operation as compared to the pre-operative χ2 value (χ2 = 76.79). The standard deviation of preoperative corneal astigmatism was statistically significant (P < 0.05) at 2.17 ± 1.08 D. Following the surgical procedure, the remaining astigmatism was measured at 0.41 ± 0.26 D. The data showed a notable gap in statistical significance (t = 4.281, P < 0.05). Conclusion: The AcrySof Toric IOL was a reliable solution for managing corneal astigmatism in cataract patients with myopia, demonstrating excellent long-term rotational stability.

Published: April 2024

We designed an improved direct-current capacitor voltage balancing control model predictive control (MPC)for single-phase cascaded H-bridge multilevel photovoltaic (PV) inverters. Compared with conventional voltage balancing control methods, the method proposed could make the PV strings of each submodule operate at their maximum power point by independent capacitor voltage control. Besides, the predicted and reference value of the grid-connected current was obtained according to the maximum power output of the maximum power point tracking. A cost function was constructed to achieve the high-precision grid-connected control of the CHB inverter. Finally, the effectiveness of the proposed control method was verified through a semi-physical simulation platform with three submodules.

Effect of Whitefly (Bemisia tabaci Genn.) Infestation on the Growth Parameters of Eggplant (Solanum melongena L.) in Kebbi State, Nigeria
Authors: Mustapha Abubakar , Sanusi Muhammad , Bhupendra Koul , Anas Hamisu , Danladi Garba Hani
Published: April 2024

Whiteflies (Bemisia tabaci Genn.) are aggressive hemipteran species that depend primarily on leaf tissue for their nourishment, causing substantial damages and yield losses in their hosts. This study was carried out to assess the effect of whitefly infestation on the growth parameters of one of the commercial eggplant cultivars (round green Solanum melongena L) under filed conditions. The trial consists of four treatments (T1= 15, T2= 30, T3= 45 and control (T4) = 0 whiteflies/plot) replicated four times. The result revealed that all the parameters assessed are negatively affected by whitefly infestation with plants in treatment (T3) being most affected while those in T1 are least affected. The dry weight recorded least value (1.1 g/leaf) having the highest percentage reduction (69.11%) followed by leaf area with 152.5cm2 (48.83% reduction) while the number of leaves was least affected recording 50.3 leaves/plant (18.09% reduction) at 90 days after infestation in 2022 experiment. In 2023 experiment, similar results were recorded with plants in T3 being most affected. Dry weight of the leaves had the lowest value (1.3g/leaf) representing the highest reduction (68.30%) followed by the leaf area with 167.3cm2 (44.8% reduction) with the number of leaves also being least affected, recording 52.1 leaves/plant representing 9.40% reduction with plants in treatment T1, at 90 days after infestation. The highest reduction in yield was also recorded with plants in T3 (92.10, 90.10%) while the least was observed in T1 (86.8 and 85.70%) for the respective trials (2022 and 2023). The result shows the level of susceptibility of the variety examined to whitefly infestation, demonstrating the urgent needs for the development of eco-friendly and sustainable whitefly management regimes for improved eggplant production in the area.
Juventud Revolucionaria en el segundo periodo del MIR (1967-1969): ¿relevo, superposición o ruptura generacional?
Authors: González Alarcón Javier , Ganter Solis Rodrigo
Published: April 2024

Esta investigación describe y analiza la ruptura generacional del Movimiento de Izquierda Revolucionaria en el contexto del Tercer Congreso realizado en 1967, en el que una nueva generación asume la conducción del movimiento. Partiendo de los estudios en juventudes y del enfoque de la historia reciente, se plantea la hipótesis que una ruptura generacional no debilita o diluye los procesos de cambio político-sociales, sino que les inyectaría nuevas energías, contenidos y velocidades a dichos procesos, permitiendo la incorporación de nuevos actores, mentalidades, prácticas y subjetividades políticas. Se utiliza un método cualitativo de análisis de contenido que considera la recolección de datos de revisión de archivos desarrollados por el mismo movimiento. Los resultados confirman que esta ruptura generacional se expresaría en dos niveles, en primer lugar, una ruptura que de carácter dialéctico y, en segundo lugar, una ruptura con un carácter eminentemente político.

A través de una investigación cuantitativa no experimental tipo encuesta, se comparan las concepciones epistemológicas sobre la Historia de estudiantes de secundaria colombianos (N=764) y españoles (N=648). Para efectos de la recolección de información se empleó un cuestionario cuyos ejes principales de indagación estaban sustentados en los debates sobre aprendizaje histórico derivados de la teoría de la conciencia histórica. Los resultados indican que, en el estudiantado que participó en la investigación perviven y se entremezclan diversas formas de constitución de sentido alrededor de la Historia entendida como conocimiento, hecho que evidencia que el proceso de comprensión de los fundamentos y desarrollo del aprendizaje histórico de los jóvenes está definido por una alta complejidad, la cual, pone en cuestión perspectivas unidireccionales de análisis sobre sus posicionamientos epistémicos.
Germán Domínguez Gajardo y la extensión cultural durante la dictadura cívico-militar chilena
Authors: Alvarado Leyton Matias
Published: April 2024

En este artículo se estudia el paso de Germán Domínguez Gajardo dentro de la institucionalidad cultural durante la dictadura cívico-militar chilena, específicamente entre 1973 y 1990. Para esto se ahonda en su biografía y su quehacer dentro de distintas entidades culturales, principalmente a través de documentos oficiales y de prensa del período. Se propone así que Domínguez desempeñó un papel clave no solo como un engranaje de la dictadura, al estar involucrado –y encabezar– algunas de sus entidades, sino que también fue gracias a su gestión y, en particular, a su propuesta de extensión cultural, que la institucionalidad cultural sufrió un cambio considerable por aquel entonces.

Natural Language Processing (NLP) is a fascinating field of study that teaches computers to understand and use human language. This means that computers can read, write, and even translate text just like humans. NLP has many practical uses, such as categorizing text, identifying the tone of language, recognizing names in text, translating languages, and answering questions. NLP has come a long way since it was first developed. In the past, it relied on strict rules to understand language, but now it uses advanced techniques like machine learning and deep learning to understand text. However, there are still some challenges in NLP, such as understanding the meaning of words in context and considering cultural differences. Despite these challenges, NLP is being used in many different areas, from healthcare and finance to education and customer service. NLP is transforming the way humans interact with computers and is making it easier to extract important information from large amounts of text.

The present study compares the thermal and energy performance of refrigerators with varying volumetric capacities when faults occur. Simulated faults include the malfunction of the fan attached to the evaporator and the airflow return area obstruction in the freezer. The proposal above included three intensity levels for each fault. Both refrigerators were instrumented to measure temperature conditions within the fresh food compartment and the freezer. In addition, during the test period, energy consumption was measured until thermal stability was reached in both compartments. The effect of each fault’s levels was compared with the reference condition for each refrigerator, which was without faults, as they left the factory. The results show that the fan fault caused the most significant variation in the thermal condition of both refrigerators. The temperature increased from 2°C to 4°C in the fresh food compartment, and from 1°C to 14°C in the freezer. The above causes warmer spaces compared to the reference refrigerator. Consequently, each refrigerator's energy consumption increased from 36% to 65%.

The exposome-centered approach marks a significant shift in occupational and environmental epidemiology, prioritizing a holistic evaluation of environmental exposures throughout an individual's life to elucidate their effects on health. Unlike traditional methods that single out environmental factors for their direct health impacts, this approach seeks an integrated analysis of all non-genetic influences, encompassing specific and general external environments and internal responses. While acknowledging environmental factors' pivotal role in chronic diseases and global mortality, existing methods struggle with precisely measuring and analyzing the broad spectrum of exposures and their combined effects. The exposome framework addresses these gaps through advanced omics technologies, refined exposure assessment models, and comprehensive data analytics. Yet, its application faces hurdles like the requirement for substantial infrastructure, cross-disciplinary training, and new statistical techniques for high-dimensional data analysis. Recent endeavors in applying the exposome concept show its promise in improving our understanding of environmental and occupational health, underlining its importance in advancing epidemiological research and public health. This abstract condenses the rationale, challenges, and ongoing efforts to incorporate the exposome into epidemiol-ogical studies, emphasizing its potential in enhancing the field.

The transition towards large-scale intensive pig farming methods has resulted in an increase in cases of complex, mixed infections, and secondary infections. Porcine circovirus (PCV), the causative agent of PCV disease (PCVD), is a small nonenveloped DNA virus containing a single-stranded circular genome. Previously, PCV was even considered nonpathogenic to pigs. However, a novel strain of PCV, designated PCV-2, has been associated with various disease syndromes in pigs over the last 5 years. PCV-2 primarily induces post-weaning multisystemic wasting syndrome, characterized by clinical signs such as debility, dyspnea, palpable lymphadenopathy, diarrhea, and pallor or icterus. PCV-2 is now recognized as an important emerging pathogen. Early diagnosis and disease prevention have become crucial for effective pig farm management. However, clinical diagnosis may be complicated by antibiotic treatment and atypical disease symptoms. To ensure accurate pathology diagnosis, it is essential to integrate robust laboratory diagnostics with traditional methods. Surface-enhanced Raman Scattering (SERS) spectroscopy has emerged as a potentially powerful technique for whole-organism fingerprinting, enabling rapid identification of bacteria. Biosensors utilizing SERS offer promising capabilities for sensitive and quick detection of bacterial pathogens, thereby reducing diagnosis time. In this study, our aim was to characterize and evaluate a SERS-based diagnostic system for detecting and identifying PCV-2 present in pooled swine sera and feces. We compared the spectra of PCV-2 recovered from the specimens to those of pure PCV-2 to determine the PCV-2 molecular fingerprint. Our results demonstrated successful detection, identification, and classification of PCV-2 in swine sera and feces using SERS. SERS provided reproducible molecular spectroscopic signatures suitable for analytical applications. This approach presents a new and potent tool for real-time surveillance of animal viral pathogens in clinical settings.

This paper provides a comprehensive review of information technology (IT) initiatives to address health disparities and evaluate their outcomes. Health disparities, defined as unequal health outcomes and access to healthcare across different population groups, are a persistent challenge globally. IT, including telehealth, electronic health records (EHRs), mobile health (mHealth) applications, and data analytics, presents innovative opportunities to mitigate these disparities. The review discusses the successes and challenges of these IT initiatives, highlighting their potential to enhance healthcare access, improve the quality of care, and promote health equity. Telehealth has been instrumental in bridging the gap for remote and underserved populations, while EHRs have improved care coordination. mHealth applications offer personalized health interventions, and data analytics is crucial in identifying and addressing health disparities. However, the effectiveness of these IT solutions is hindered by barriers such as the digital divide, lack of digital literacy, and privacy concerns. The paper calls for continued investment in accessible and equitable IT initiatives. It emphasizes the need for a multidisciplinary approach involving policymakers, healthcare providers, and IT professionals to implement effective solutions. Through this review, the paper aims to contribute to understanding how IT can be leveraged to combat health disparities, offering insights for future research and policy development.
