Published: October 2021

Although mental disorders are common among university students, the majority of students with mental health issues do not seek out treatment during their academic life. The aim of this study was to evaluate the effects of a novel group approach- choir singing, and its potential impact on stress, via salivary cortisol levels and self-reported stress levels in university students during 4 sessions of choir singing. It was based on a quasi-experimental research conducted with 25 Brazilian university students. Each choir singing session lasted 60 minutes. A question was asked before and after the intervention: what is the level of your stress? Salivary cortisol was collected before and after the intervention. After the choir singing intervention, there was  a statistically significant reduction in self-reported stress (p<0.0001) and salivary cortisol levels (p<0.0001). This research suggests that choir singing can reduce the self-reported stress of university students after 4 weeks of follow-up with ∆= 45.83% and salivary cortisol levels in the first week with ∆= 3.57%.

Published: October 2021

COVID-19 is a global pandemic (Jaihah) that brings hardships (Haraj). This has affected all aspects of our life. The United Nations Development Programme reported that uncertainties due to this global pandemic are manifold. Under a 'High Damage’ scenario, the world could see a staggering 251 million people driven into extreme poverty by the pandemic, bringing the total number to one billion by 2030. The Singapore government had made swift and comprehensive response by forming multi-ministry task force and galvanise various organisations, at all levels, including faith-based institutions to manage and address the multiple challenges in hands. This paper highlights the 3Rs approach adopted by the government through their policies, measures, and actions on various aspects of sustainability including climate and social changes and how the rest of the stakeholders come together for greater impact, with specific focus on the response from the Muslim community.
Mineral Kritikal dari Perspektif Keselamatan Negara
Authors: Abdul Aziz Badhrulhisham
Published: October 2021

Mineral kritikal (menurut United States Geological Survey, USGS) boleh dikategorikan sebagai 'komoditi mineral yang mempunyai kegunaan penting serta tiada pengganti berdaya maju, namun berdepan dengan potensi gangguan bekalan, ditakrifkan sebagai kritikal kepada keselamatan ekonomi dan negara'. Dalam tempoh 10 tahun yang lepas, negara-negara seperti Australia, Kesatuan Eropah (EU) dan Amerika Syarikat telah mula berusaha mengenal pasti, mengkategori dan memprioritikan secara strategik mineral kritikal, contohnya nadir bumi. Walaupun Malaysia kaya dengan mineral berharga (dengan anggaran nilai rizabnya sebanyak RM 4.11 trilion; dimana kemungkinan besar RM 1 trilion boleh dianggarkan sebagai nilai mineral kritikal), ia masih belum membangunkan pelan komprehensif untuk mineral kritikal yang boleh diekstrak. Kertas kerja ini, yang berdasarkan laporan tempatan dan antarabangsa bersama-sama dengan data yang boleh dipercayai, mencadangkan untuk Malaysia mula meneroka usaha mengenal pasti kedudukan sumber-sumber penting dengan sewajarnya. Seterusnya negara perlu mewujudkan perancangan strategik yang komprehensif dalam memelihara dan menggunakan mineral kritikal ini, dengan mengambilkira risiko rantaian bekalan dan pembangunan teknologi yang merupakan perkara antara paling utama kepada keselamatan negara.
Keynote Speech: Colonial-Capitalism and Its Impact on Natural Resources in The Colonised World
Authors: Noor Farish A
Published: October 2021

This keynote speech was delivered at the International Conference on Interdisciplinary and Strategic Studies (ICRIS) on August 12, 2021. It explains the concept of colonial-capitalism and highlights the importance of understanding the underlying logic of capitalism behind the praxis of colonialism. From the middle to late stages of colonialism over the past 500 years, the underlying logic of colonial conquest continued to evolve. Initially, it was the Crusades that prompted the Europeans to start their exploration but then it was the conflicts and competition among the European powers themselves that galvanised their desire to conquer the world. This speech also illustrates how colonial-capitalism has changed our view of nature and our human relationship with the natural world, which in turn has influenced how we manage our natural resources. It concludes by reflecting on how we are still living in the long shadow of the 19th century and why the struggle for mental liberation continues until today.

Published: October 2021

Purpose: The main aim of the study was to assess correlates associated adherence among Female Sex Workers on PrEP in the study. This was done through determining level of knowledge on PrEP, level of adherence, correlates affecting adherence and analysis of strategies to enhancing PrEP adherence.

Materials and Methods: A cross sectional analytical study with mixed method using both qualitative and quantitative data collection method was carried out between March and May 2021. Three hundred and forty-five Female Sex Workers (FSWs) were enrolled in the study. Data was collected using structured questionnaire from study participants after having their consent. Three focus group discussions (FGD) were conducted for those FSWs who will not be involved in the quantitative arm of study. Key Informant Interview was conducted with service providers using Key informant interview (KII) guide. Data collected was entered into Excel spread sheet in password protect computer. Data analysis was carried out in, Univariate analysis, bivariate analysis and multivariate analysis. Statistical Package of Social Science (SPSS) version 20.0 was   used for analysis. Data was presented using graphs and Tables.

Results:  The study found that 72% did not know the name of PrEP, 39% reported to have missed PrEP with 33% having missed appointment for PrEP refill. Qualitative data showed that PrEP engagement meetings should be conducted monthly to enhance PrEP adherence. The respondents who had reminders on when to take medication was as well associated with adherence (p=0.014) compared with those not using reminders. The study also found out that employment status was associated with adherence to PrEP medication (P=0.050) with FSW who were salaried being 2.5 times more likely to adhere to PrEP medication compared to those who were not salaried.

Unique contribution to theory, practice and policy: The Ministry of Health should ensure that targeted PrEP counselling is done during the initiation for the eligible clients. The information and telecommunication department to work on SMS reminder system in order to remind FSWs using PrEP about appointment dates for the pill pick up thus enhance adherence to FSWs using PrEP. The procurement department should work together with pharmacy department to ensure that there is enough stock for PrEP at every clinic. This will help to ensure that adherence is achieved for the FSWs on PrEP.

Sentiment analysis is the methodical recognition, extraction, quantification, and learning of affective states and subjective information using natural language processing, text analysis, computational linguistics, and biometrics. People frequently use Twitter, one of numerous popular social media platforms, to convey their thoughts and opinions about a business, a product, or a service. Analysis of tweet sentiments is particularly useful in detecting if people have a good, negative, or neutral opinion. This study assesses public opinion about an individual, activity, commodity, or organization. The Twitter API is utilised in this article to directly get tweets from Twitter and develop a sentiment categorization for the tweets. This paper has used Twitter data for two separate approaches, viz., Lexicon & Machine Learning. Lexicon based approach further categorized in Corpus-based and Dictionary-based. And various Machine learning-based approaches like Support Vector Machine (SVM), Naïve Bayes, Maximum entropy are used to analyse Twitter data. Neural Network (NN), Decision tree-based sentiment analysis is also covered in this research work, to find out better accuracy of the approaches in the various data range. Graphs and confusion matrices are used to visualise the results of the analysis for positive, negative, and neutral remarks regarding their opinions.

Os principais resultados evidenciaram que existem pontos a serem corrigidos por parte da gestão do programa para que iniciativas como esta, ocorram de maneira mais efetiva.
COMPRAS PÚBLICAS COMO INSTRUMENTO DE DESENVOLVIMENTO LOCAL
Authors: Rossoni Roger Alexandre
Published: October 2021

Segundo estimativa do Ministério do Planejamento, Orçamento e Gestão, as compras públicas movimentam valores de aproximadamente 15% do PIB. O presente estudo pretende verificar empiricamente o impacto das compras públicas como instrumento de desenvolvimento socioeconômico nos municípios do Paraná. Por meio da utilização da regressão linear múltipla aplicada a dados referente às compras públicas dos municípios paranaenses em 2013, variáveis socioeconômicas e ao Índice IPARDES de Desempenho Municipal (IPDM), foi verificado o efeito das compras públicas no processo de desenvolvimento no Estado do Paraná. O modelo estimado demonstra que as compras públicas, quando realizadas em fornecedores locais, implicaram em um maior IPDM nos municípios paranaenses. Apesar do modelo demonstrar uma relação positiva entre a realização de compras públicas em fornecedores locais e o IPDM, verifica-se que o impacto das compras públicas no IPDM é de pequena proporção. Desta forma, a utilização das compras públicas como fator estratégico para desenvolvimento socioeconômico apresenta suas limitações.  A utilização das compras públicas como indutor do desenvolvimento local necessita de um maior debate e da adequação da legislação vigente referente ao processo de licitação
Condition Assessment of Reinforced Concrete Systems with Fusion Bonded Epoxy Coated Rebars
Authors: Kamde Deepak K. , Kessler Sylvia , Pillai Radhakrishna G.
Published: October 2021

Corrosion assessment of reinforced concrete (RC) structures with fusion-bonded-epoxy (FBE)-coated steel rebars is a challenge because the common inspection methods and data cannot be applied or interpreted in the same way as that for the systems with uncoated rebars. If corrosion detection tools based on techniques such as half-cell potential (HCP), linear polarization resistance (LPR), or electrochemical impedance spectroscopy (EIS) are used for the assessment of systems with FBE-coated steel rebars without considering the difference in the electrochemical conditions between coated and uncoated systems, then the interpretation can result in the inability to detect ongoing corrosion. Therefore, the objective of this paper is to examine the suitability of these inspection methods and data to be applied to the RC systems with FBE-coated steel rebars. For this, the suitability of test methods on HCP, LPR, and EIS for assessing corrosion conditions of RC structures was assessed using laboratory specimens and field structures. Field investigation using HCP shows that the HCP could not detect corrosion of FBE-coated steel rebars unless the coating was severely disbonded due to corrosion of steel rebars. Also, the suitability of test methods on HCP, LPR, and EIS was assessed by additional laboratory specimens. Although complex, only the EIS technique could reliably detect the corrosion conditions of the FBE-coated steel rebars embedded in concrete. Therefore, a way forward to assess RC structures using the EIS technique is proposed.
Comparing the kinematics of back squats performed with different heel elevations
Authors: Monteiro Pedro Henrique Martins , Marcori Alexandre Jehan , Nascimento Vitor Bertoli , Guimarães Anderson Nascimento , Okazaki Victor Hugo Alves
Published: October 2021

Purpose

Back squat (BS) is a popular exercise owing to its capacity to develop lower limb strength. During BS, trunk inclination and knee range of motion (RoM) are relevant aspects of a proper technique, and these movement kinematics parameters can be positively altered with official weightlifting shoes lifting the heel 13 mm above the ground. Wedges are a low-cost alternative to lifting the heel to different heights, but movement kinematics adaptations with higher elevations, above 25 mm, are not well described in the literature. Thus, we compared the effect of different heights of heel wedges on BS kinematics.

Methods

Fifteen experienced recreational weightlifters (22 ± 5.4 years; 83 ± 11 kg; 179 ± 6 cm; 5 ± 2.1 years of BS experience) were conveniently selected. Three randomized conditions were applied: barefoot (B), 25-mm (W25), and 50-mm wedges (W50). BS movement was assessed by kinematic analysis with an optoelectronic camera system.

Results

After ANOVA, the post-hoc indicated significant RoM differences in reducing trunk (F = 27.27; p < 0.01) and increasing knee (F = 16.87; p < 0.01) flexions between conditions. Post-hoc analysis verified decreasing trunk inclination (B > W25 > W50; p < 0.05) and increasing knee (B < W25 < W50; p < 0.05) RoM with increasing wedge height.

Conclusions

Higher wedges allowed positive adaptations by promoting a more upright trunk position and greater BS depth. Using a heel wedge can be a low-cost and viable strategy to optimize BS technique in a variety of training settings and contexts.

Purpose

This study investigated the occurrence of relative age effect (RAE) in Brazilian elite soccer athletes depending on age categories, playing position, and competitive level.

Methods

Data from 2660 male elite soccer athletes who participated in the 2019 Brazilian soccer championships were analysed. To determine RAE, the players were divided by their quarter of birth: Q1 (January-March), Q2 (April-June), Q3 (July-September), and Q4 (October-December). Data were obtained from the Brazilian Soccer Confederation (CBF) official website, and from each club’s website when no information was available at the CBF website. Were included the athletes who participated in the 2019 Brazilian soccer championships in series A and B. Data were organized in accordance with age categories (under-20 or senior), playing position (forwards, midfielders, defenders, and goalkeepers), and competitive level (Series A or B).

Results

An overrepresentation of soccer players born in the first quarter of the year was found when compared with the other quarters, whereas players born in the last quarter of the year were underrepresented, regardless of the age category and competitive level. Regarding playing position, an overrepresentation of soccer players born in the first quarter of the year was found for all playing positions in both age categories, except for the goalkeepers in the senior category.

Conclusions

Our results showed a prevalence of RAE in U-20 and senior age categories in elite Brazilian soccer athletes, in both competitive levels, and for all playing positions, except for goalkeepers in the senior category.

Asian countries have dealt with COVID-19 with varying levels of success. The WHO’s lack of effective leadership in the region has resulted in increasingly contested global health governance. The pandemic continues to undermine global health, and the highly interdependent economies in Asia have exposed the speed with which pandemics can now spread. The security of migrant workers is more precarious than ever. Millions have been stranded and face limited access to health services. Public Health in Asia during the COVID-19 Pandemic: Global Health Governance, Migrant Labour, and International Health Crises provides an accessible framework for understanding the COVID-19 pandemic in Asia through the lens of global governance in health and labour.
Contested Legitimacies
Authors: Grimm Jannis Julien
Published: October 2021

Since the overthrow of President Mursi in mid-2013, Egypt has witnessed an authoritarian rollback and shrinking spaces for civil society. Nationalist discourses have villified popular protest and channelled pressure for reform into a state-centric model of governance. Despite this hostile environment for social mobilization, protest has persisted. Contested Legitimacies explores this resilience of contentious politics through a multimethod approach that is attuned to the physical and discursive interactions among key players in Egypt’s protest arena. Drawing from a unique archive of sources, it investigates the rise and fall of different coalitions of contenders, from the Tamarod uprising against Mursi, to the Anti-Coup resistance against the military coup, to the challenges posed by the Tiran and Sanafir island campaign to Al-Sisi's regime. It highlights the decisive impact of battles fought in a discursive arena on the conditions of possibility for street politics: In postrevolutionary Egypt, a contest over the meaning of political legitimacy cemented political polarization, limited social movements’ coalition choices, and ultimately paved the way for a restoration of autocracy.

Published: October 2021

Knowledge Graph is a semantic network that reveals the relationship between entities, which construction is to describe various entities, concepts and their relationships in the real world. Since knowledge graph can effectively reveal the relationship between the different knowledge items, it has been widely utilized in the intelligent education. In particular, relation extraction is the critical part of knowledge graph and plays a very important role in the construction of knowledge graph. According to the different magnitude of data labeling, entity relationship extraction tasks of deep learning can be divided into two categories: supervised and distant supervised. Supervised learning approaches can extract effective entity relationships. However, these approaches rely on labeled data heavily resulting in the time-consuming and laborconsuming. The distant supervision approach is widely concerned by researchers because it can generate the entity relation extraction automatically. However, the development and application of the distant supervised approach has been seriously hindered due to the noises, lack of information and disequilibrium in the relation extraction tasks. Inspired by the above analysis, the paper proposes a novel curriculum points relationship extraction model based on the distant supervision. In particular, firstly the research of the distant supervised relationship extraction model based on the sentence bag attention mechanism to extract the relationship of curriculum points. Secondly, the research of knowledge graph construction based on the knowledge ontology. Thirdly, the development of curriculum semantic retrieval platform based on Web. Compared with the existing advanced models, the AUC of this system is increased by 14.2%; At the same time, taking "big data processing" course in computer field as an example, the relationship extraction result with F1 value of 88.1% is realized. The experimental results show that the proposed model provides an effective solution for the development and application of knowledge graph in the field of intelligent education.

An Intelligent and Data Driven Mobile Platform for Early Childhood Development using Machine Learning and Data Mining
Authors: Ding Maggie , Sun Yu
Published: October 2021

In China almost 96 million children live in rural areas. Some of these children suffer from malnutrition since parents or guardians do not have knowledge of nutritional plans or how to calculate nutritional values. However, most of the Chinese population has access to a mobile device. This paper proposes a mobile application, which runs on the IOS and Android platforms, to calculate nutritional values and recommend a nutritional menu. EZ Nutrition and Education is a mobile app that targets millions of parents and caregivers in rural China and provides a solution to the regions’ early childhood underdevelopment problems. It provides recommendations for healthy meals and age-appropriate educational activities, measures children’s daily intake of calories and macro-nutrients (protein, carbs, and fats), and provides a way to have fun through activities that teach skills and values so as to prevent the underdevelopment of rural children’s physical, intellectual and mental growth. We applied our application to a group of participants (ages 6-12) and conducted a qualitative evaluation of the approach. The results show that the nutritional calculator feature can help parents improve the nutritional health of their children. Though two of the underweight participants lost weight and two of the overweight participants gained weight while using the recommended nutritional plan, we believe that the recommended nutritional menu could be an excellent feature for this application after we adjust some of the parameters since some parents claimed they could not follow the recommended menus.
FencingEstimate: A 3D Game-Based Interactive Driving Simulation Training System using Artificial Intelligence and Computer Vision
Authors: Lei Weixuan , Sun Yu
Published: October 2021

Training for fencing during the pandemic has changed from what it was beforehand. Students have been taking lessons online, and instead of fencing with peers, students now train by watching and analyzing fencing videos. Learning fencing from watching videos of world class fencers is an effective way of learning. However, sabre fencing is so fast that many inexperienced fencers are unable to capture the important information by watching short clips. Therefore, they are unable to learn techniques such as sabre fencing just from watching videos. This paper traces the development of an application that can utilize computer vision and pose estimation to analyze fencing video clips and output accurate scored points as well as the techniques used within the given clips. We applied our application to help less experienced fencers improve their ability to recognize points and conduct qualitative evaluations of different fencing techniques.

not only worried about this fatal communicable virus but also other difficulties that are being declared by the patients.One such deadly problem being reported in patients in India in current times, who have produced positive result for COVID-19 and are slowly regaining health, is a fungal disease called mucormycotic or black fungus. With many such cases being announced incities and states like Mumbai Bengaluru, Delhi, and Gujarat it has provoked an extra wave of fear among the general population.Mucormycosis, previouslycalledaszygomycosis, is an uncommon fungal infection. It is caused by the mould related to mucorales, that is found mainly in decayed wood organic matters soil and leaves. They can cause blackening of skin, redness, inflammation,sores and can encroach the eyes, lungs and even the brain, substantiating to be dangerous if left without treatment. So, it is necessary to knowthe etiological factors and prominent symptoms associated withclinical implications of mucormycosismainly invasiveness and perforation into deeper part of the bone.That is why it is necessary to identify immediately any possible badsigns of mucormycosisarising in both, COVID-19 patients, and other individuals. The report must be communicated to the healthcare workerswithout delay so that treatment can be provided at a suitable time and the patient recovers completely.

Introduction and Aim:Diabetes mellitus, especially type II DM is one among the most prevalent metabolic diseases in the global scale. One of the commonest complications of diabetes mellitus is vestibulopathy affecting the inner ear. Malondialdehyde (MDA) obtained from lipid peroxidation of poly unsaturated fatty acids (PUFA) is an important compound that generally serves as one of the key markers for oxidative stress. The aim of the study is to prove the significance of MDA in Vestibulopathy in Type-2 i.e.,non-insulin dependent diabetes mellitus.

 

Methodology: A cross-sectional study of 100 diabetic patients of age group between 35 years and 50 years were tested for vestibular function by electronystagmography(Commonly used test to determine and evaluate vestibular system). Based on the biothermal caloric stimulation the Clausen butterfly chart was generated and thus the code is ascertained. Serum levels of Malon-di-aldehyde were assayed by TBARS method (Thiobarbituric acid Reactive substances).

 

Results: The study proved, that there was a 4 times increased risk of developing vestibulopathy with increasing duration of diabetes. It also proved that there was an increased risk of developing vestibulopathy in diabetic patients, having MDA > 2?mol/L.

 

Conclusion: Thereby the study confirmed the clinical significance of periodic screening of MDA levels, in diabetic patients, particularly those with uncontrolled/poor glycemic control & with longer duration of diabetes. Estimation of their serum MDAlevels and vestibular function by the electronystagmography test, is advised in order to prevent the occurrence of diabetic vestibulopathy at the earliest and also to prevent the worsening of any such, other complications associated with the disease.

Published: October 2021

Introduction and Aim: Essential oils have been used from ancient times to treat different gram-positive and gram-negative bacterial-related infections. The study aims to screen the antibacterial, anti-quorum sensing activity of origanum oil against the common infection causing gram-negative and gram-positive bacteria.

 

Material andMethods: The MIC (minimum inhibitory concentration) and antibacterial activity of origanum oil against the eight bacterial species, namely, Pseudomonas aeruginosa, Shigella flexneri, Salmonella enterica, Klebsiella pneumoniae, Streptococcus pneumonia, Streptococcus pyogenes, Staphylococcus aureus, and Enterococcus faecalis, was assessed by broth-dilution method and well diffusion method. The anti-quorum sensing activity was analyzed using bioreporter strain CV026 at sub-MIC concentrations, while the cytotoxicity of the origanum oil was analyzed using the SW480 cell line.

 

Results: The oil's antibacterial activity was analyzed by measuring the clear inhibitory zone diameter, and maximum inhibitory zone of 36.66 mm zone against Staphylococcus aureus (Gram-positive) and 33.33 mm against Salmonella enterica (Gram-negative) of origanum oil was measured. And the minimum inhibitory zone of 16.66 mm zone of Enterococcus faecalis (Gram-positive) and 19.66 mm against Klebsiella pneumoniae (Gram-negative) of oil was noted. And the lowest MIC (0.1 mg/ml) of oilwas found against Streptococcus pneumonia. The oil significantly inhibited the violacein pigment production (30.29 %) at 0.02 mg/ml concentration (this oil concentration did not significantly affect the growth curve). The in vitro cytotoxicity assay shows that the oil inhibited the SW480 cells growth with increasing concentration.

 

Conclusion: The origanum oil possesses antibacterial and anti-quorum sensing activity and can be used as an alternative for treating tested bacterial infection.

Introduction and Aim: Oilseeds are an important source of nutrition in developing countries, which are either consumed directly or as snacks. However, the presence of anti-nutritional factors limits their use. This study evaluated the potential application of probiotic Lactobacillus plantarum in reducing the anti-nutritional content in peanut, mustard and sesame.

 

Materials and Methods: Peanuts, sesame and mustard seeds were coarsely ground, defatted by Soxhlet extraction method using hexane and fermented by submerged fermentation method using Lactobacillus plantarum. After fermentation for 72hrs, the contents were centrifuged and the pellets in addition to defatted raw sample were analyzed for anti-nutrients like polyphenols, oxalates, trypsin inhibitors and lectins using standard protocols.

 

Results: Polyphenol content was reduced by 26.40, 46.70 and 41.50%, while oxalate content exhibited 61.50, 32.70 and 37.70% reduction in peanut, mustard and sesame respectively. Trypsin inhibitor activity was reduced by 80.00, 12.13 and 77.78%, while lectin exhibited 87.50, 62.50 and 64.87% reduction in peanut, mustard and sesame respectively.

 

Conclusion: Peanut showed maximum reduction in oxalates, trypsin inhibitors and lectins followed by sesame and mustard. However, highest polyphenol reduction was exhibited in sesame. Hence, from the present investigation, it is found that fermentation may be a promising tool in reducing anti-nutritional factors from oil seeds.
