Creating a Responsive Society for Effective Implementation of Inclusive Education: The Case for the Adoption of the Socioecological Model
Authors: Obisike Ebere Ellison , Adalikwu-Obisike Justina
Published: July 2024

Inclusive education increases human capital such as knowledge, skills, social interactions, and health, which enhance individuals’ chances for higher earnings, social mobility, and sustainable growth within communities and countries. For inclusive education to be successful, a written plan or an individualized education plan has been advocated for. The concept of this plan defines special education programs, accommodations, and services that a school board will provide for students or the practice of helping students meet their educational goals through educational programs that modify certain course requirements to be either above or below age-appropriate, grade-level expectations, and the provision of alternative course or class expectations that help students acquire knowledge and skills that are not part of the curriculum.  Therefore, using this plan, the proponents of inclusive education advocate for the inclusion of individuals living with physical and mental impairments, such as sensory or mobility limitations, intellectual disabilities, language disorders, and behavior disorders, to promote education access to marginalized groups in society. On the other hand, the opponents of inclusion education argue that the concept of a written plan, or an individualized education plan, seems ineffective and paradoxical to the general government’s policy on an inclusive classroom. A review of existing literature on inclusive education shows that the inconsistencies in both the concept and implementation of inclusive education are the outcomes of the dichotomy between an unresponsive society, which encourages a stagnant or ill-prepared system, and a rapidly evolving political correctness environment. As a way forward, we recommend the adoption of a social-ecological model for creating a responsive society for the effective development and implementation of inclusive education policies based on the findings of our consolidated literature review.

Financial Assessment of Microgrid’s Independence using RES and Hydrogen-Based Energy Storage
Authors: Nikologiannis Marios , Mozakis Ioannis , Iliadis Ioannis , Katsigiannis Yiannis
Published: July 2024

The main difficulty that microgrids face is an economically feasible state of self-sustainability. The unpredictable behavior of dispersed Renewable Energy Sources (RES) and their stochasticity along with the usually high variability of electricity demand is a challenge for the stability of a microgrid. Therefore, innovative models for the development of energy systems that integrate new technologies in optimal and sustainable ways are required. Green hydrogen production is an emerging technology aiming to solve such problems through its use as a storage system within a viable business scheme. Integrating hydrogen production with RES and storage systems can enhance energy independence and economic opportunities. The focus of this paper is the proposal of a profitable financial scheme that leads to sufficient levels of the system’s independence from a main grid. Such an approach is implemented by a cost-effective pathway for a microgrid located in Crete through the simulation and investigation of its system that achieves high levels of selfsufficiency by incorporating RES backed by hydrogen-based energy storage. The proposed methodology relies on assessing the system’s sizing through the calculation of values that replicate its operation, with Net Present Value (NPV) serving as an indicator of the scheme’s profitability. The financial evaluation of the investment predicts, under specific assumptions, a total initial cost equal to 12,037,150.00 EUR, and an NPV of 20 years equal to 2,489,862,897.40 EUR.

Published: July 2024

Introducción: El consumo de sustancias psicoactivas es una problemática de salud pública, que conlleva consecuencias a nivel personal, familiar y comunitario. La probabilidad de que una persona consuma sustancias psicoactivas depende de varios factores. Objetivo: Identificar los factores asociados en los pacientes que ingresan al servicio de urgencias con trastorno por sustancias psicoactivas en el Instituto Neuropsiquiátrico Nuestra Señora del Carmen (INSECAR) en Santa Marta durante el periodo 2020 a 2022. Métodos: Estudio cuantitativo, observacional, de corte transversal, donde se revisaron 415 historias clínicas de la muestra calculada de los pacientes que ingresaron por urgencias con trastorno por sustancias psicoactivas en el INSECAR de Santa Marta periodo 2020 a 2022. Resultados y conclusiones: La mayoría de los pacientes eran hombres de 19 a 30 años, de vivienda urbana, escolaridad primaria completa y conformación familia monoparental, con una prevalencia del 40.7% de trastorno afectivo bipolar y 37.3% ninguna comorbilidad, el 47.71% estuvieron hospitalizados de 31 a 60 días. La sustancia más utilizada por primera vez fue marihuana, la prevalencia de uso de las sustancias fue 100% marihuana, 84,6% cocaína, 72.8% benzodiacepinas, 59.3% Bóxer, 13.5% cigarrillo y 27.2% alcohol. Dentro de los factores asociados se encontró que la cocaína incrementa tres veces el riesgo de larga estancia hospitalaria (OR 3.26 IC95% 1.24-8.5 p=0.011), mientras que el uso de cigarrillo disminuye el riesgo en un 67% (OR 0.33 IC95% 0,12-0,89 p=0.023). Para establecer correlaciones y causalidades se sugiere realizar más estudios en esta población con un grupo control y seguimiento a largo plazo.

Нора (Hole) in Russian Epics
Authors: Toporova Tatyana V. ,   Institute of Linguistics, Russian Academy of Sciences
Published: July 2024

The purpose of the paper is to comprehensively analyze the lexeme nora in Russian epics and to determine its role in the mythopoetic model of the world. A special research method has been developed — a scheme for describing an epic word, which arose on the basis of a thesaurus description of a folklore word and lexicological studies of a number of key concepts in other archaic traditions that have undergone fundamental processing. It consists of several blocks: phonomorphological, textual, extralinguistic, grammatical, etymological, derivational, semantic, syntactic and poetic. Нора is attested in epics about Dobrynya and the snake, mainly in plur., such a significant predominance of which is not accidental: many holes serve to mark the entrances to the other world, which they collectively form. Accus. is the most frequent case, realized in the construction to go into a hole / holes, describing the motif of the hero’s penetration into the snake’s underground possessions. The synonyms of the hole are an open field, denoting in epics an alien and dangerous space not controlled by the heroes, and the damp earth with its recesses, which are directly related to the lower world with its chthonic inhabitants (snake); antonyms are home and Kiyev-grad, to which it is opposed as chaos, undeveloped space to the developed, unsocialized locus to the society. The attributes of the hole mark the possessor (snake) and the most essential property of the abyss as the lower zone of the universe (deep). Нора finds an attraction to the mythological motif of snake-fighting in the “basic myth”; нора (< Indo-E. *ner-, nor-) has analogies in other Indo-European designations of the other world.
Sanctuaries in the Discourses of Sacred Geography
Authors: Lebedev Vladimir Yu. ,   Tver State University, Prilutskiy Alexander M. ,   Herzen State Pedagogical University of Russia
Published: July 2024

The paper explores the phenomenon of sanctuaries from the perspective of religious semiotics. The authors have identified the ambivalence of the perception of a mystical place by folk religion: a mystical place can be simultaneously perceived both as a topos in which ritual is performed, and as an object of worship. At the same time, stable ritualogemes of veneration of mystical places are developed, forming elaborate ritual complexes. Analysis of the mytho-semiotic specificity of narratives about sanctuaries made it possible to propose their typology: places of power, mysterious places, places of refuge, places metonymically associated with special religiously significant events. Specal areas that are dangerous and harmful to humans are considered separately. The study includes analyzing of basic mytheologems that form the discourse of sacred geography. It has been proven that the narrative about sanctuaries is not only formed as a result of the functioning of the mechanisms of mythological hermeneutics characteristic of folk religiosity, but also turns out to be capable of generating new mythological plots. At the same time, a religious studies analysis of the specifics of sacred sites revealed the impossibility of their unambiguous confessional identification due to the presence of syncretic mythologemes in their interpretation. Stories about visiting sacred places and the experiences of various events and states associated with these visits are actively mythologized and become sources for the generating of new semantics and semiotics of sacred geography.

Fish are an important component in the human diet, providing a rich source of proteins, micronutrients, and polyunsaturated fatty acids (PUFA). The chemical composition of fish derivatives is high in PUFA, making them more susceptible to lipid oxidation, consequently developing unpleasant aroma and flavor due to the formation of rancid compounds, which contribute to off-flavors. Various chemical and instrumental methods have been proposed in recent years to assess the stability and quality of foods concerning lipid oxidation. The most used methods to evaluate primary oxidation products are peroxide index and conjugated dienes, while for secondary products, thiobarbituric acid reactive substances (TBARS) and chromatographic methods (fatty acids, volatile compounds) are used. In addition to these methods, microbiological analyses are crucial to assess microbial activity, as spoilage microorganisms can alter the texture and sensory attributes of foods through the degradation of proteins, carbohydrates, and lipids. Finally, sensory evaluation involving panelists allows for monitoring the gradual formation of lipid oxidation compounds and microbial deterioration in products.

Land use changes in tropical regions have increased, leading to rising environmental stress in Java, Indonesia. Food shortages have driven land conversion and expansion, which increases peak flows during the rainy season and reduces water storage in the dry season, heightening flood risks. Research on integrated catchment hydrology is crucial. This study examines the relationship between land use, runoff, and sediment in the Bogowonto Upper Watershed using SWAT hydrological modeling. The SWAT model helps understand hydrological processes at the watershed scale and the impact of land use changes on runoff and sediment dynamics. The sensitivity of SWAT model parameters varies in the Bogowonto Upper Watershed. Runoff sensitivity analysis indicates a +62% increase with a 50% change in CN value, showing high sensitivity. A 50% change in vegetation cover results in a +50% model output, indicating moderate sensitivity. Slope, Ksat (saturated hydraulic conductivity), and bulk density are fairly sensitive, while AWC is slightly sensitive. For sediment, a 50% increase in CN value results in a +47% change, and a 50% increase in vegetation cover leads to a +58% model output, showing moderate sensitivity. The model, run from 2014-2019, shows excellent accuracy with NSE of 0.82, RRMSE of 0.43, R² of 0.83, and PBIAS of 9.8%.

Published: July 2024

As the application of steel structures in construction continues to grow, research into their seismic performance is becoming increasingly important. This paper focuses on steel structure connections, specifically those between components with varying profiles such as H-profiles, box-profiles, and L-profiles. Additionally, it encompasses three core areas: seismic performance (bearing capacity, ductility, stiffness), initial defects (initial cracks, residual stresses, manufacturing imperfections), and damage models (weld fractures, bolt failures, plate buckling). In addition, this paper employs experimental testing and finite element, with a focus on conducting parametric analyses for the connections. Based on the primary findings, the presence of initial defects such as cracks, residual stresses, and manufacturing imperfections can lead to premature failure, concentrating damage near welds and exacerbating stress concentrations. This adversely affects factors like fatigue strength, fracture toughness, and buckling strength, ultimately reducing the seismic performance of the connections. Moreover, factors like bolt over-tensioning, geometric deviations in plate components, and corrosion can further impact bearing capacity, fatigue performance, and ductility. Crucially, these initial defects not only compromise the seismic resistance of structures but also increase the risk of structural failure. However, majority of existing research has focused on monotonic and cyclic loading studies, with limited exploration of connections under seismic conditions. Acknowledging this gap, this paper outlines a future research agenda aimed at refining the design of steel structure connections. This initiative seeks to mitigate potential adverse consequences stemming from formidable seismic events, thereby enhancing the overall resilience of these crucial connections.

Cool-pavement technology has emerged as a potential solution to environmental issues posed by the urban heat island phenomenon, with surface temperature acting as a vital parameter in the evaluation of its thermal performance. This study focuses on the thermal performance results of modified asphalt concrete mix, wherein palm oil shell (POS) serves as a replacement for fine aggregate. Modified asphalt samples prepared using the Marshall Mix Design, with varying degrees of fine aggregate substitution (0%, 10%, 20%, 30%, 40%, and 50%), underwent a 24-hour continuous surface temperature measurement over a span of 20 days, under real-world tropical climate conditions. The findings demonstrated that sample P5, comprising 50% fine aggregate substitution, exhibited the highest reduction in surface temperature when compared to control sample P0, registering a significant decrease of up to 3.29°C during the period of peak solar intensity. ANOVA test-based statistical analyses confirmed significantly lower temperatures for all test samples, barring sample P1 (10% aggregate replacement), relative to the control sample. The results highlight the efficacy of POS as a fine aggregate substitute in asphalt concrete, significantly lowering asphalt pavement surface temperature, thereby endorsing the potential use of POS-modified asphalt in cool-pavement applications.

Numerical analysis is important to predict material behaviour without require an experimental implementation. This manuscript focuses on a numerical prediction establishment of a direct recycled aluminium alloys AA6061 undergoing Taylor Cylinder Impact test using Johnson-Cook model in HyperWorks Radioss. The numerical setup was first validated against the experimental data at the velocity range of 179 to 212 m/s. Good agreement between simulation and experimental data was obtained within the range that exhibits a mushrooming shape fracture mode. A parametric study was then conducted to study the deformation behaviour of the selected recycled aluminum alloys within the validated range at various geometrical settings. The analysis was made by focusing on the post-impact configuration of the projectile at different impact velocities in terms of residual length, deformed diameter, and the final length-to-diameter ratio. It was found that a broader projectile experienced a less significant reduction in its final length (Lf/Lo goes from 0.87 to 0.9 for projectile diameter 9mm to 34mm) and a smaller increase in the deformed diameter compared to a thinner projectile (Df/Do goes from 1.18 to 1.12 for projectile diameter 9mm to 34mm). It was found that a thinner projectile experienced more diameter expansion than length reduction post impact. In addition, a longer projectile experienced more residual length reduction (Lf/Lo goes from 0.92 to 0.87 for projectile length 2mm to 14mm) and more radial deformation compared to the one with a smaller initial length (Df/Do goes from 1.06 to 1.18 for projectile length 2mm to 14mm). All projectiles showed more significant changes on the deformed diameter compared to the changes in residual length post-impact. The results helped the understanding of a critical aspect of the deformation behaviour of recycled aluminum alloy AA6061 more effectively compared to experimental work implementation.
