Abstract

Objectives
This study aimed to assess unilateral molar-incisor hypomineralization (MIH) on the stomatognathic system in children, investigating if greater impairment exists on the affected side in terms of postural and masticatory activities and occlusal force contacts.
Materials and Methods
Fourteen children with unilateral MIH (mean age: 7.92 years) were included in this cross-sectional split-mouth observational study. Electromyography (EMG) evaluated masseter and temporal muscle activity during various jaw postures and habitual chewing. Occlusal force contacts were measured using T-SCAN®. The analyses compared the side with MIH to the side without the defect. Statistical analysis employed the Shapiro-Wilk test, Wilcoxon signed-rank test, and paired t-test.
Results
Muscle hyperactivity was observed on the unaffected side, indicating greater voluntary contraction compared to the affected side for the temporal muscle at rest (p = 0.01) and masseter muscle in right laterality (p = 0.02). No significant difference was found in occlusal force between the sides analyzed.
Conclusions
Children with MIH exhibit compromised stomatognathic system functionality, with enamel defects potentially disrupting balance and leading to functional limitations.
Clinical Relevance:
Children with unilateral MIH may present muscle hyperactivity on the unaffected side, suggesting enamel defects could lead to stomatognathic system imbalances with clinical implications for dentists.

Published: May 2024

Abstract

With the rapid advancements in artificial intelligence (AI), it is vital to develop psychometrically sound measures of public attitudes toward this technology. The present study aimed to refine a pool of candidate items to create a concise yet robust inventory for assessing attitudes toward AI. Using a dataset of 604 participants from the general population of the United States, a pool of 96 candidate items was subjected to iterative Rasch analysis to reduce the number of items while ensuring psychometric robustness. The resulting scale, named the Artificial Intelligence Attitudes Inventory (AIAI), consists of two 8-item subscales measuring positive and negative attitudes toward AI. Analyses revealed that these subscales are distinct constructs rather than opposites on a single continuum, and they are only weakly related to psychological distress. The AIAI provides a concise yet comprehensive measure of positive and negative attitudes toward AI that can be efficiently administered alongside other measures. The findings underscore the multifaceted nature of public perceptions of AI and highlight the need for further research into the profiles and determinants of these attitudes. As AI continues to shape our world, the AIAI offers a valuable tool for understanding and monitoring public sentiment toward this transformative technology.
Analysis of Government Budget Deficit in Ethiopia: The Vector Auto Regression Model Approach
Authors: Alene Desta Birru 
Published: May 2024

Abstract

Over the previous several decades, Ethiopia's economy has been troubled by an ongoing budget deficit. Taking the problem into consideration, this paper used vector auto-regression model estimation techniques to shed light on the drivers, trends, and threshold levels of budget deficit in Ethiopia from 1979/80 to 2021/2022. The model estimation revealed that current account balance, consumer price index, and domestic borrowing have a positive effect on budget deficits, whereas institutional quality, financial deepening, and real gross domestic product havenegative effect in the long run. In the short run, domestic borrowing positively affects budget deficit whereas borrowing, institutional quality, and real gross domestic product affect negatively. The findings of the threshold study indicate that the projected threshold level of budget deficits is 3%. Any ratio of budget deficits over this threshold, on the other hand, has a positive impact on the current account balance, while any rate below this threshold has a negative impact. In order to lower the government budget deficit, it is advised that sensible economic policies be adopted, such as a simple and effective tax system, import substitution, and export promotion.
Causal Nexus Real Effective Exchange Rate, External Debt, Liquidity and Stock Value: Case study on Canada: Vector Error Correction Model (VECM) Approach
Authors: ARARSO ABRAHAM ZEWDU 
Published: May 2024

Abstract

Canada has currently one of the largest economies in the world. However, the Economy of Canada has witnessed various boom and bust over the last several decades. Real GDP growth has recorded on upward trend growth from 1980’s until 2007. However, in the aftermath of the Global financial crisis, the GDP growth rate of Canada has fallen to just below 2 percent. During the same time period, the level of Canada’s external debt, real effective exchange rate and money supply has grown exponentially. Likewise, the expansion of capital market in Canada reinforced the robust economic expansion and caused upsurge in the level of stock traded. This research examines the causal relationship between real effective exchange rate, external debt, liquidity and stock value in Canada between 1980 until 2016. To check the stationarity of the data, the research conducted Augmented Dickey-Fuller unit roots test. The result shows that after taking their first difference all variables turned to become stationary. Based on Johansen tests for co-integration, the study variables are co-integrated in the long run, therefore the research used Vector Error Correction Model (VECM). Furthermore, to verify the suitability of the data, the research conducted diagnostic tests like normality test, la-grange multiplier test and Heteroskedasticity Test. The estimation rest shows that there is both long run and short run causality among the research variables. In the short run, Canada’s liquidity has short run causality on Real effective exchange rate and Stock values. Conversely, real effective exchange rate and Government Debt have short run causal effect on Canada’s liquidity level. Likewise, stock value traded and real effective exchange rate have short run casual effect on Canada’s government debt. In the long run, the VECM estimation revealed that there is a long run causal relationship running from liquidity, government debt and stock value towards the Canada’s Real effective exchange rate (REER).
Application of Second Order Perturbation Theory to AnalyzeHeisenberg Hamiltonian in Ultra-thin Films of Spinel Ferrite
Authors: Nuthalapati Rusheel Sai 
Published: May 2024

Abstract

The Heisenberg Hamiltonian’s solution with second-order perturbation is explored in the context of non-aligned cubic spinel ferrimagnetic materials. This investigation delves into perturbations stemming from alterations in angle at the boundary between adjacent cells. As the number of cells (N) increases from 2 to 3, the energy peaks exhibit sharper profiles, and their positions shift along the energy-angle curve. Interestingly, the intervals between successive major peaks remain consistent. Visualizing the relationship between total energy, angle, and stress in three dimensions, the plot’s smoothness improves with higher N values. Notably, the energy diminishes as the number of layers increases, suggesting disparate behaviors between oriented and non-oriented films. In the scenario where N=2, minor peaks adjacent to major peaks emerge. Furthermore, when the second-order anisotropy constant remains uniform across the film for N=2, the film’s behavior resembles that of an oriented film.

Authors: Demir Mehmet 
Published: May 2024

Abstract

This paper investigates research on the evaluation of primary mathematics curricula over seventeen years to provide significant guidance on the essential issues and a set of fundamental principles for promoting mathematics achievement in Turkey and internationally. To do this, I aim to contribute to the primary mathematics curriculum and research by synthesising relevant research and identifying potential trends, highlighting key research findings, identifying challenges in curriculum implementation, and highlighting gaps in the literature. I synthesised ninety-four studies from 2005 to 2022 using descriptive content analysis, categorising the data according to overall mathematics curricula, including curriculum objectives, content, learning process and assessment, teacher, curriculum, and institutional challenges in implementing the curriculum. My critique highlights strengths and weaknesses in the literature, suggests research priorities for researchers to guide future research, and outlines specific implications for policymakers, leaders, and teachers in a mathematics curriculum.

Published: May 2024

Abstract

Background:
Dizziness is common reason for visit to the emergency department (ED), which impacts patient well-being and places significant demands on healthcare resources. Despite its prevalence, the trends of patient presentation and healthcare utilization has not been assessed for decades.
Objectives
To comprehensively analyze 10-year trends of patient presentation and healthcare utilization of dizziness attributed visits to the ED.
Methods
The National Hospital Ambulatory Medical Care Survey (NHAMCS) was used to obtain data for patients that visited the emergency department for dizziness from 2010 to 2019. Nationally representative estimates were derived for patient demographics and diagnostics. Trend analyses were conducted to investigate potential patterns and implications.
Results
A total of 1.3 billion dizziness attributed ED visits were estimated from 2010 to 2019 with a significant increase per year and a 49.23% increase over the decade (p<.001). Diagnostic imaging has significantly increased for this population (p=.005). However, the amount of head CT scans ordered have remained stable (p=.201). The number of medications provided during these visits have significantly increased (p=.005), without any difference in the rate of being admitted to the hospital (p=.231).
Conclusion
The rate of ED visits attributed to dizziness has continued to rise in the recent decade. There are notable presentation rates for ED dizziness visits depending on patient age, sex, and race. Although overall utilization of imaging has increased, orders for head CT has remained stable.

Introducción: en la atención hospitalaria, la provisión de comidas integra el proceso de recuperación de los pacientes. Los alimentos que se utilizan pueden afectar la calidad del ambiente. Objetivo: identificar las características de los diferentes patrones de menú, así como los impactos ambientales de los alimentos utilizados en las dietas de un Hospital Público Universitario (HPU) de Uruguay. Métodos: estudio retrospectivo utilizando datos secundarios. El período investigado fue el año 2021 y el primer semestre de 2022. Se evaluaron las prescripciones de dietas totales para alimentación oral (VO) y suplementaria (AS). Se analizaron las variables: a) valor energético en kilocalorías (kcal); b) huella hídrica (HH) - para dietas VO; c) valor energético; d) generación de gases de efecto invernadero (GEI) - para insumos utilizados para la AS. Resultados: el HPU sirvió 317.380 comidas durante los tres semestres. De las 24 opciones para la prescripción de dietas VO, 13 tipos representaron más del 93% de la cantidad total de prestaciones. En cuanto a los 21 tipos de alimentos utilizados en las prescripciones dietéticas, 6 fueron de origen animal. En la evaluación del impacto ambiental se identificó una diferencia de hasta 51% de HH entre los tipos de dietas VO. En AS, el grupo de fórmulas enterales para adultos representó el 88,37% del consumo total. El grupo de fórmulas infantiles tuvo el mayor impacto en la emisión de GEI. Conclusiones: además de la atención con prestaciones dietéticas el servicio de alimentación hospitalario debe considerar los impactos ambientales de su oferta alimentaria.

Published: May 2024

Camu camu (Myrciaria dubia) is a fruit from the Peruvian Amazon, highly valued for its high content of vitamin C, which is concentrated in its pulp. Due to this nutritional characteristic, it is processed into juices and extracts. However, its industrialization generates a considerable amount of waste. Therefore, its utilization is vital to reduce environmental pollution. The content of phenolic compounds in the peel and seed of camu camu has been studied, indicating that factors such as drying temperature and the method of stabilizing the concentrated powder are key to preserving its antioxidant activity. The objective of the study was to evaluate two drying temperatures (50 and 65°C) on camu camu seeds and peels, analyzing their effect on the total phenol content and the efficacy of atomization encapsulation and molecular inclusion of the concentrated extract at the optimal temperature. Extraction was conducted out with food-grade ethanol solvent at a ratio of 1:40 (g/g), at 55°C for 30 minutes, then concentrated to 60% in a rotary evaporator. At 50°C, a lower of phenolics (4979.99 ± 94.24 mg gallic acid equivalent (GAE)/100g of sample) was found in the peel and seed mixture, and total anthocyanins in the peel (47.82 ± 3.93 mg cyanidin/100 g sample).. Atomization and molecular inclusion of the concentrated extract showed efficacy in in retaining the encapsulated total phenols. In conclusion, using a temperature of 50°C for drying has a lesser impact on the content of polyphenols. Additionally, two alternatives for stabilizing the extract are presented: with maltodextrin and molecular inclusion with cyclodextrin, both equally effectives.
