Published: July 2023

Given the potential negative impact reliance on misinformation can have, substantial effort has gone into understanding the factors that influence misinformation belief and propagation. However, despite the rise of social media often being cited as a fundamental driver of misinformation exposure and false beliefs, how people process misinformation on social media platforms has been under-investigated. This is partially due to a lack of adaptable and ecologically valid social media testing paradigms, resulting in an over-reliance on survey software and questionnaire-based measures. To provide researchers with a flexible tool to investigate the processing and sharing of misinformation on social media, this paper presents The Misinformation Game—an easily adaptable, open-source online testing platform that simulates key characteristics of social media. Researchers can customize posts (e.g., headlines, images), source information (e.g., handles, avatars, credibility), and engagement information (e.g., a post’s number of likes and dislikes). The platform allows a range of response options for participants (like, share, dislike, flag) and supports comments. The simulator can also present posts on individual pages or in a scrollable feed, and can provide customized dynamic feedback to participants via changes to their follower count and credibility score, based on how they interact with each post. Notably, no specific programming skills are required to create studies using the simulator. Here, we outline the key features of the simulator and provide a non-technical guide for use by researchers. We also present results from two validation studies.

Published: July 2023

The paper assesses the value relevance of the tenure of auditors and size of audit firm by using empirical data from actively traded firms on the floor of Nigerian Exchange Group. Data for the study were obtained from the published annual reports and accounts of 124 quoted companies in Nigeria between 2012 to 2021. The average -monthly share price of the fourth month after accounting year end of all sampled firms was utilized as the dependent variable of the study in order to establish the value relevance of accounting information in the financial statements, Incorporating the explanatory variables of the study (auditor tenure and control variables) into The Ohlson’s 1995 price model quantitative approaches such as descriptive statistics, correlation, and panel corrected standard errors regression analysis were used in analyzing the data for the study. Findings of the study indicate that auditor tenure and audit firm size led to significant positive influence on market reaction in the first month after the release of annual reports and accounts of sampled firms. This means that, auditor tenure and audit firm size were found to be value relevant to users of accounting information in Nigeria. The study recommends that investors should consider the audit tenure and auditors size when making investment decisions and prioritize firms that have been audited by big auditors and by integrating small audit firms, as well as firms whose audit tenure is on average of five to six years in line with International best practices, rather than ten years as stipulated by the Code of Corporate Governance and CBN.

This study examines the moderating role of ownership concentration on the effect of audit characteristics on audit report lag of listed consumer goods firms in Nigeria. The ex-post facto research design was adopted, secondary data was extracted from annual reports and accounts of listed consumer goods firms in Nigeria. The population of the study is twenty-one (21) and the sample size consist of fifteen (15) for ten years (2012-2021). Six (6) companies were flitter out from the study due the technical suspension by NXG during the period of study. Census sample techniques were adopted. PCSEs regression model was employed as technique of data analysis. The findings of the study revealed that the Audit Committee Size (ACS) and Audit Committee Meeting have a positive and significant effect on Audit Report Lag (ARL). Also, the Audit Committee Financial Expertise (ACFE) revealed a positive and insignificant effect on Audit Report Lag (ARL), while the Audit Committee Independence is established to have a negative and insignificant effect on Audit Report Lag (ARL). However, with consideration of moderating role ownership concentration, the Audit Committee Size (ACS) and Audit Committee Meeting (ACM) is found to have significant negative effect on Audit Report Lag (ARL), while the Audit Committee Financial Expertise and Audit Committee Independence are found to have a positive and insignificant effect on Audit Report Lag (ARL). The study concludes that ownership concentration moderates the effect of audit committee on Audit Report Lag. The study recommended that the management of the study firms should continue to sustain the frequency of meetings and size or numbers of the committee in their respective audit committee since the two committee have been empirically proven to have significantly reduced the timeframe of reporting their financial reports.

Published: July 2023

We investigate the impact of the surface-brightness (SB) limit on the galaxy stellar mass functions (GSMFs) using galaxy catalogs generated from the Horizon Run 5 (HR5) simulation. We compare the stellar-to-halo-mass relation, GSMF, and size–stellar mass relation of the HR5 galaxies with observational data and other cosmological simulations. The mean SB of simulated galaxies are computed using their effective radii, luminosities, and colors. To examine the cosmic SB dimming effect, we compute k-corrections from the spectral energy distributions of individual simulated galaxy at each redshift, apply the k-corrections to the galaxies, and conduct mock surveys based on the various SB limits. We find that the GSMFs are significantly affected by the SB limits at the low-mass end. This approach can ease the discrepancy between the GSMFs obtained from simulations and observations at 0.6 ≲ z ≤ 2. We also find that a redshift survey with an SB selection limit of

Quantifying the Key Factors Affecting the Escape of Planetary Atmospheres
Authors: Luo J. , He H.-Q. , Tong G.-S. , Li Jiao
Published: July 2023

The habitability of Earth-like planets is an increasingly important subject in astrophysics and in planetary sciences. Atmospheric escape plays a vital role in the evolution of the habitability of Earth-like planets. By systematically analyzing the numerical simulation results of the interactions between the planetary atmospheres and the stellar winds, in this work, we evaluate various factors related to the atmospheric nonthermal ion escape rates, including planetary parameters (e.g., mass, density, radius, semimajor axis, etc.) and stellar wind parameters (e.g., density, velocity, and interplanetary magnetic field (IMF) strength). Furthermore, we determine and quantify the key factors affecting the planetary atmospheric nonthermal ion escape rates. Our results show that the correlation coefficients between planetary atmospheric nonthermal ion escape rates and stellar wind density, IMF strength, and the ratio of the planetary radius to the planetary semimajor axis are 0.98 (0.88), 0.95 (0.81), and 0.87 (0.59), respectively, in the scenario of maximum (minimum) dynamic wind pressure. This means that the planetary atmospheric nonthermal ion escape rates increase with the increasing stellar wind density, the increasing IMF strength, and the increasing ratio of the planetary radius to the planetary semimajor axis. Generally, the nonthermal ion escape rates of planetary atmospheres are more sensitive to stellar wind parameters than to others. In addition, we determine the functional relations of the above three significant parameters for evaluating and quantifying the effects of such key physical factors on the nonthermal ion escape rates of the planetary atmospheres. Our findings will be very useful for better understanding the key factors that influence the escapes of planetary atmospheres.

Published: July 2023

Abstract

In winter 2019, an excursion to the central and eastern parts of Georgia was conducted, focusing on arboreal species and other carabids overwintering under bark or at the base of trunks. Other habitat structures were also investigated. The work was done as part of ongoing studies in preparation of a new checklist of Georgian Ground Beetles and to contribute to the faunistic as well as ecological knowledge base for the main natural areas of this country. Forty-three taxa were recorded. The arboreal species Dromius agilis (Fabricius, 1787), the plant-dwelling species Demetrias imperialis (Germar, 1823), and Paradromius suturalis (Motschulsky, 1844), and another six species (Microlestes corticalis (Dufour, 1820), M. fissuralis (Reitter, 1901), M. fulvibasis (Reitter, 1901), M. luctuosus Holdhaus in Apfelbeck, 1904, Pterostichus leonisi Apfelbeck, 1904, and P. strenuus (Panzer, 1796)) are new for Georgia. In some sites, the number of recorded specimens under bark, in litter, or in the upper soil was very low, probably due to specific climatic conditions (e.g., very low humidity). It is supposed that in these areas, most of the individuals reside deeper in the soil during periods of low activity or hibernation. The number of Dromius individuals overwintering under bark near the stem base increased with altitude. The relevance of special survey methods in the winter for ground beetles is emphasized.

Synchronization analysis of coupled fractional-order neural networks with time-varying delays
Authors: Li Biwen , Cheng Xuan
Published: July 2023

In this paper, the complete synchronization and Mittag-Leffler synchronization problems of a kind of coupled fractional-order neural networks with time-varying delays are introduced and studied. First, the sufficient conditions for a controlled system to reach complete synchronization are established by using the Kronecker product technique and Lyapunov direct method under pinning control. Here the pinning controller only needs to control part of the nodes, which can save more resources. To make the system achieve complete synchronization, only the error system is stable. Next, a new adaptive feedback controller is designed, which combines the Razumikhin-type method and Mittag-Leffler stability theory to make the controlled system realize Mittag-Leffler synchronization. The controller has time delays, and the calculation can be simplified by constructing an appropriate auxiliary function. Finally, two numerical examples are given. The simulation process shows that the conditions of the main theorems are not difficult to obtain, and the simulation results confirm the feasibility of the theorems.

Published: July 2023

Background

Childhood malnutrition remains a significant public health problem impacting the physical and mental growth if school aged children, particularly in limited-resource countries.

Objective

The study objective was to assess levels of physical activity, patterns of screen time (S.T.), the relationship between physical activity and screen time patterns, and how these factors affect growth status (adjusting for socioeconomic status).

Methodology

A cross-sectional study included 3,834 children between 6–14 years attending pre-selected schools. Teachers, students, and parents were invited to fill out a standardized questionnaire, and Body Mass Index (BMI) was calculated using Center for disease control (CDC) centile charts. A Chi-square was performed to see the possible association between any height and weight abnormalities and all possible risk factors. Multivariate logistic regression was applied to see the effect of variables significantly associated with univariate analysis.

Results

Approximately 2,447 (63.8%) children were between 11–14 years old and 1,387 (36.2%) were between 4–10 years old. The mean height was 143.71 ± 16.51 centimetres, the mean weight was 36.5 ± 12.9 kilogram, and the mean BMI was 17.16 ± 3.52. Multivariate logistic regression status and junk food combined affected stunting socioeconomic status was significantly associated with being underweight p = 0.001.

Conclusion

Childhood obesity and stunting remain significant problems in Pakistani school-going children. These are significantly associated with poverty, a lack of physical activity opportunities, and available food quality.

Published: July 2023

Internet memes are commonly associated with the communication of interests and opinions on social networking sites, and are used to share experiences and negotiate common ground through various contexts. Previous studies on identity construction and the use of Internet memes have not paid sufficient attention to identity construction in education-centred Internet memes. Hundreds of memes were selected from Instagram handles that contain memes on general issues out of which only seventeen representative education-centred Internet memes were selected to illustrate identity negotiation and construction in education-centred memes and to examine identity construction in educational contexts through memes. Adopting aspects of van Dijk's critical discourse analysis (CDA) complemented with Kecskes' sociocognitive approach to common ground, and Staszak's otherness as the framework for the study, data were subjected to discourse analysis. Memes give different representations and identities in the information of all and transformation of higher education through the online space.

Authors: Olajimbiti Ezekiel Opeyemi , Dada Samuel Ayodele
Published: July 2023

The marketization of higher education, which is becoming competitive due to the growing number of tertiary institutions, has attracted the attention of scholars. Previous studies have focused on promotional strategies in institutions' websites, prospectuses, and social media, while little attention has been paid to promotional emails. This study, therefore, complements existing studies by examining the rhetoric in promotional emails of tertiary institutions within the context of student enrollment. The data includes 80 emails sent by 20 higher education institutions to prospective students and were subjected to discourse analysis using Bhatia's genre analysis. The findings reveal three move structures: self-promotion, incentive, and invitation through rhetorical strategies of the institution's achievements, scholarship opportunities, and event participation using linguistic resources that indicate intentions to persuade potential applicants. The findings show how tertiary institutions attempt to build friendly relationships with prospective students through persuasion.
Sentiment Analysis of the Consumer Review Text Based on BERT-BiLSTM in a Social Media Environment
Authors: Zhou Xueli
Published: July 2023

In this paper, a BERT-BiLSTM-based consumer review text sentiment analysis method in the e-commerce big data field is proposed. First, the unlabeled text is trained using the BERT training model for the language introduced in the deep learning, and then the pre-training model of the text data is delivered by the learning textual features and data to extract deeper vectors. Second, the BiLSTM model is applied to simultaneously obtain contextual information so as to illustrate optimal textual features. Finally, a corresponding sentiment analysis model relative to the consumer review text is constructed by combining the BERT model with BiLSTM to better merge the context for classifying sentiment and improving the final feature vector accuracy for the sentiment classification results. Simulated by experiments, the method proposed in this paper was compared with another three methods using the same data set. The results obtained indicate that the proposed method has the highest precision, recall, and F1-Measure, and the values reach 92.64%, 90.32%, and 91.46%, respectively.

Published: July 2023

Digital transformation of enterprises is driving the need for a digital identity to recognize people for delivering services. The implementation of digital identity is complex, requiring several technological solutions and much coordination. Capturing and processing data is challenging because biometric issues may arise due to imaging errors. This article addresses this issue and proposes a computer vision-based framework for contactless recognition process using a focus group discussion approach for inputs from experts. The proposed framework enhances image capturing process, extraction of high-quality features from captured images, image processing, contactless face detection, and authentication. The study also derives lessons for other biometric-based identity projects based on image analysis. The proposed framework can be used as a reference for understanding multidimensional perspectives, scalability, and adoption of technological solutions in other similar projects in developing countries in future.

Endocrine tumours are commonly encountered in clinical practice. The demographic data in a specific part of the country can be harnessed only from a tertiary care referral center. We aimed to analyze the epidemiological pattern of various histopathological subtypes of four major endocrine glands in the body in Northwestern India. In this retrospective chart review analysis, we reviewed three lakh records of histopathologically proven tumours coming to four major pathology departments and laboratories in Jaipur, Rajasthan over five years; of which 3081 were from patients with endocrine tumours. We included these endocrine tumours in our study and the results were obtained. The collected data were analyzed and results were obtained using Microsoft Excel 2019 Version 2107. Thyroid tumours were the most common tumours (96.8%) with adrenal, parathyroid and pituitary in order. Percentage of malignant cases among the thyroid disorders was 20.55%. Multinodular goitre (50.3%) and papillary carcinoma thyroid (77.67%) topped the benign and malignant thyroid tumours respectively. Females in 21 to 40 years age group were most affected in thyroid tumours. Pheochromocytoma was the most common adrenal tumour (60%) most commonly affecting females in the age group pf 21 to 40 years of age. Parathyroid adenoma constituted the majorchunk of parathyroid tumours (86.9%) with no sex predilection and affecting patients mostly in the age group of 31 to 45 years. Pituitary adenoma was found in 34 of 35 cases with a female preponderance and a wide range of affected age groups (21 to 50 years). Different histopathological subtypes of endocrine gland tumours have a varied epidemiological profile in NorthwesternIndia and incorporation of this knowledge will help improve the clinical acumen of the treating personnel in this part of the country.

Authors: Samarawickrama S. T. N. , Edirisinghe J. C. , Kanuwana K. P. N. G.
Published: July 2023

Although Moringa oleifera is identified as a nutrient-dense, superfood with increasing demand in the international market, it is recognized as an underutilized plant in Sri Lanka with vast potential to improve rural income. Thus, the objective of this study is to identify the existing potential of the plant, to act as an income generator. Value chain analysis was done qualitatively, in order to map the existing value and to identify main actors, channels and constraints along value chains. Dry and intermediate ecological zones were selected and a total of 47 participants were drawn purposively, and interviewed through face-to-face interviews and telephone conversations in order to gather primary data needed. Two value chain maps were identified related to leaf and pod – based products and exporters add a considerably higher amount of value to products. Leaf collector was identified as an actor who arbitrary gains higher profits with a little value addition. It is concluded that even though there is a high potential and return for M. oleifera based products, the communication gap among actors in the value chain and lack of awareness among local consumers hinder the possible income generation.

With the development of technology, most people got the chance to engage in digital marketing activities. Online shopping is a trending facility that improves day by day and social media advertisements play a major role in customers’ online purchase intention. The purpose of this study was to observe how the features of social media advertisements affect the online purchase intention of customers in Sri Lanka when purchasing products including agricultural products. The social media advertisement features that affect online purchase intention (creativity, customer feedback, entertainment and information in advertisements) were considered in this study. A google form questionnaire was used to gather data and 312 responses were collected. Confirmatory Factor Analysis and Structural Equation Modeling were used for the data analysis. After analyzing the gathered data, it was found that informative advertisements and creative advertisements on social media platforms have a direct impact on online purchasing intention. Also, the results indicated that customer feedback affects purchase intention through information. Entertaining online advertisements have an impact on purchase intention through their creativity. This study focused on only four features in social media advertisements. Therefore, future researchers should address the other advertisement features as well. The findings of this research can be used to make advertisements more useful and profitable for advertisers as well as sellers.
A Goodness of Fit Test for a Survival and Count Bayesian Joint Model: In the Presence of Clusters
Authors: Kumaranathunga K. U. S. , Sooriyarachchi M. R.
Published: July 2023

Bayesian statistical model fitting was an uncommon approach until recently, causing a lack of assessment techniques for these models. However, with the enhancement of computational facilities and advanced estimation techniques, Bayesian models have become popular. Though there are developed goodness of fit (GOF) tests available for classical multilevel models including joint modelling of mixed responses, there is no suitable model based GOF test to be applied on such a model which is fitted under a Bayesian framework. Therefore, this study focused on developing a suitable GOF test for multilevel Bayesian joint models having survival and count responses which are two frequently occurring data types in many fields. The novel test is developed mainly based on four classical GOF tests, including the well-known Hosmer-Lemeshow test and, the Bayesian concepts such as Bayesian credible intervals and regions. In addition, a simulation study has been used to examine the properties of the GOF test together with an application to a real-life example. The novel test performed well in terms of power and acceptable in terms of Type I error rates. Overall, the test performed well with small sample sizes.

Published: July 2023

Child Sexual Abuse has been a global epidemic with devastating consequences. One in four girls and one in six boys have been experienced some form of sexual abuse in their tender age in the world. According to Police statistics, Child Sexual Abuse (CSA) cases is growing in recent years in Sri Lanka too. Galle is among the four districts where the reported child abuse cases high and the reported CSA complaints are increasing extraordinarily. Also, there is no previous research have been done in the Southern part of the country regarding the crisis of CSA. So, main objective of this study is to determine the key risk factors that affected to a CSA in Galle Police Division, and to develop suitable regression and machine learning models to predict the severity of CSA. 225 CSA cases reported to Police Child and Women Bureau of Galle Police Division during the period 2017 – 2020 were treated for this study. Out of twenty-one risk which were found from literature and knowledge of domain experts, sixteen variables showed a significant relationship with response variable severity of CSA according to chi-square test of association. Traditional OLR model was performed to predict severity of CSA and to detect key risk factors to a CSA with two different data selection methods. Next, machine learning techniques: Decision Tree, SVM, and PNN were trained to classify severity of CSA. Random over-sampling technique was used to overcome the class imbalanced problem persists in the dataset. Finally, bagging technique was executed to conserve robustness of models and to improve performance. The OLR model classified the severity of CSA with 68.85% accuracy. Machine learning techniques, Decision Tree, SVM and PNN model classified the severity of CSA with an accuracy of 82.15%, 77.68% and 85.25% respectively. PNN model performed with higher accuracy better than other fitted models. The results obtained from this study can be used to take precautions and to arrange awareness sessions for adults to reduce CSA in Galle Police Division. Also, the study can be extended to the whole island to reduce CSA and to make it a better place for children.
Optimal Trajectory Generation for a Quadrotor Biplane Tailsitter
Authors:   Rensselaer Polytechnic Institute, McIntosh Kristoff ,   CCDC Army Research Laboratory, Reddinger Jean-Paul , Mishra Sandipan , Zhao Di
Published: July 2023

This paper introduces a methodology for an optimization-based trajectory planner for the autonomous transition of a quadrotor biplane tailsitter (QRBP) between the flight modes of hover to forward flight and forward flight to hover. The trajectory planner uses a simplified first principles dynamic model of the QRBP in the formulation of a optimization problem for trajectory planning. Additional constraints on the trajectory are imposed based on physical limitations, such as available power, stall limits, among others. The cost function for the optimization problem is chosen to be the time-of-transition. The solution of this problem generates time-optimal state and input trajectories for transition. To validate the algorithm, the trajectories are tested on a flight dynamics simulation of a QRBP to demonstrate feasibility and tracking performance with an inner-loop PID feedback controller; and compared against trajectories generated from a heuristic approach. The results of the simulated tracking performance indicate the proposed trajectory planner is capable of generating feasible transition trajectories for the previously specified flight modes.

Published: July 2023

This paper reports on the current state of experimentation and deployment of the PMM method within the Design Office of Airbus Helicopters (AH). It shows that it is possible to efficiently carry out a system engineering process based on modeling and simulation (MS4SE). It is based on simulation tools that are widely available and known to engineers in the practice of their disciplines. The PMM method has not yet been used at AH on a complete helicopter program. This is owed in part to the too recent emergence of PMM. However, PMM has gone through several qualification stages in the form of Proofs of Concept (POCs) and pilot projects conducted directly in relation with operational teams and engineering disciplines interested to PMM for the greatest benefit of end users. The paper presents results for each stage of the development cycle paying a particular attention on both ends of this cycle: from the development of the operational concept and the validation of the top-level specification to the final verification of a helicopter function on an integrated helicopter test laboratory.
An analysis of COVID-19 and spirituality among African Christian women
Authors: Igboin Benson O.
Published: July 2023

There has been increasing research into the COVID-19 pandemic and the theological responses to it. However, not much research has been done on the COVID-19 and how women, particularly in Africa, utilised spiritual resources to respond to the pandemic. This article sought to bridge this gap. The article utilised both descriptive and analytical methods, and argued that many African women were more concerned about the health of the community than their male counterparts who concentrated more on arguments about the pandemic. Gleaning from our ethnographic data carried out from the Christ Apostolic Church and the Spirit and Life Family Bible Church in Nigeria, the article used Galen Watts’ theory of ‘spirituality of and for’ to analyse how African Christian women deployed their spirituality and resources to address the existential challenges the pandemic posed. It argued that the African Christian women shunned the ‘spirituality of’ argument that relates with discursive functions of being spiritual, which does not correspond to its practical application, and adopted ‘spirituality for’ which resonates with how spiritual resources are deployed to (re)solve existential challenges towards human flourishing. This, it argued, aligns much with the theology of The Circle of Concerned African Women Theologians.Contribution: The article concluded that most women were accentuated towards ‘spirituality for’ because it is compassion-driven and responds to the existential quest for the health of the community.

Yoga Practice and Choices of Foods, Physical Activity, and Leisure
Authors: Telles Shirley , Sharma Sachin Kumar , Gandharva Kumar , Prasoon Kumari , Balkrishna Acharya
Published: July 2023

Background:

Previous surveys from countries other than India reported positive health behaviors in yoga practitioners. The present study aimed to determine with respect to yoga practitioners in India: (i) percentages of yoga practitioners who consumed specific foods, had additional physical activity and leisure activity, (ii) the association between these choices and their yoga practice, and (iii) the association of yoga with adding or avoiding specific foods and with meal timings in a day.

Materials and Methods:

This convenience hybrid-mode sampling survey was conducted on 551 yoga-experienced persons.

Results:

(1) Yoga practitioner respondents ate fruits and vegetables regularly (62.1%), did not consume animal source products (69.2%), alcohol (98.0%), or tobacco (98.4%), had a regular physical activity other than yoga (77.5%) and leisure activities (92.2%). (2) More than 150 min/week of yoga practice and experience of yoga exceeding 60 months was (a) significantly associated with (i) regular consumption of fruits and vegetables, (ii) lower consumption of sugar-sweetened beverages, animal source foods, tobacco, and alcohol (P < 0.05, Chi-square test) and (b) not associated with physical activity or leisure activities (P > 0.05, Chi-square test). (3) Yoga practitioners excluded sugar-sweetened beverages, animal-source foods and fast foods from their diet, whereas they added fruits, vegetables, and plant-based juices to their diet, with earlier first and last meals for the day.

Conclusion:

In India, yoga practitioner respondents’ choices for foods, physical activity, and leisure conform to accepted positive health behaviors. The exclusion of animal-source foods emphasizes the need for well-planned and fortified diets among vegan yoga practitioners.
Apgar Score at Various Gestational Ages
Authors: Zakerihamidi Maryam , Kianifar Sheila , Moradi Ali , Boskabadi Hassan
Published: July 2023

Introduction:

The Apgar score is an accepted method for reporting the condition of a newborn. The present study was performed to evaluate the Apgar score at different gestational ages.

Methodology:

This cross-sectional study was performed on 1161 newborns with a gestational age of 25–40 weeks born in the maternity ward of Ghaem Hospital in Mashhad during 2014–2021 with available sampling. The data collection was performed with the researcher-made checklist, including neonatal characteristics. The neonatal Apgar scores of the 1st and 5th min and the cord pH after birth were registered in gestational ages categorized to 25–28.6, 29–32.6, 33–36.6, and 37–40 weeks.

Results:

The mean 1st and 5th min Apgar scores after birth were as below: At the gestational age of <29 weeks, 6 and 7.3, at 29–33 weeks, 6.60 and 8.2, at 33–37 weeks, 7.5 and 8.7, and at more than 37 weeks, 8.2 and 9.6. There was a moderate correlation between gestational age at birth and 1st and 5th min Apgar score.

Conclusion:

Apgar score components improve in higher gestational ages; therefore, a lower Apgar score is acceptable at lower gestational ages. The results of the present study show the real Apgar score for different gestational ages. This can be a criterion for evaluating the Apgar score of the baby at any gestational age.

Published: July 2023

ABSTRACT

Aim:

The aim of this study was to evaluate the syndecan-1 expression in oral submucous fibrosis (OSF) according to grades of epithelial dysplasia.

Materials and Methods:

Twenty samples of OSF were divided into three groups: Group 1 (OSF with mild epithelial dysplasia, n = 15), Group 2 (OSF with moderate epithelial dysplasia, n = 3), and Group 3 (OSF with severe epithelial dysplasia, n = 2).

Results:

A statistically nonsignificant (P > 0.05) difference was noted when staining intensity of syndecan-1 in stratum basale were compared between OSF with mild dysplasia (O1) and OSF with moderate dysplasia (O2) (P = 0.141), O1 and OSF with severe dysplasia (O3) (P = 0.222) also between O2 and O3 (P = 1.00). A statistically significant (P < 0.05) difference was noted when staining intensity of syndecan-1 in stratum spinosum were compared between O1 and O2 (P = 0.010), O1 and O3 (P = 0.038), between O2 and O3 the difference was not statistically significant (P = 0.414). A statistically nonsignificant difference was noted when intensity of syndecan-1 expression in superficial layers of the epithelium was compared between O1 and O2 (P = 0.655), O1 and O3 (P = 0.715), also when O2 and O3 were compared, the difference was not statistically significant (P = 1.00).

Conclusion:

Downregulation of syndecan-1 antigen in OSF according to increased grades of epithelial dysplasia correlates to some extent with the disease progression.
Methods to Improve the Biocompatibility Quotient of Orthodontic Materials in Clinical Practice: A Review
Authors: Jain Nikhil , Vichare Gauri , Mall Sanjana
Published: July 2023

ABSTRACT

Biocompatibility of dental materials has always been a highly scrutinized theoretical domain that is often not given due attention in the clinical practice. Often, the lack of awareness on the part of the orthodontist of biocompatible material substitutes leads to a lack of treatment in this small but significant subset of the patient population that encounters such mishappenings. This review aimed to provide contemporary orthodontist with methods and substitutes that can be implemented in the clinical scenario and improve the biocompatibility quotient as well as the treatment outcomes. These methods will lead the way to better patient compliance in case of hypersensitivity-prone cases and a more customized approach to attain the end treatment goal while maintaining the biological integrity of the patient.
