Authors: Ozverel Cenk Serhan , Kurtulmus-Yilmaz Sevcan
Published: November 2020

COVID-19 has been recognized at the end of 2019 and has been recognized in more than 215 countries with more than 24 million reported cases. Dental practitioners were regarded under high risk of getting COVID-19 due to their working environment and the mode of transmission of the virus. Present study aimed to evaluate the awareness and assessing the knowledge of dental students and dentists on COVID-19.

The study population consisted of undergraduate students who are currently studying dentistry in Cyprus. Students were sent an onlinesurvey and data were collected on 16th of April. Survey was comprised of questions about the demography, education level of the participants, their infection control knowledge, conditions that require treatment during pandemic.

A total of 594 students with equal gender distribution joined the survey. The age group of the participants were mostly between 18-25 age (94%) with 63% pre-clinical and 37% clinical students. The majority of participants were aware that dentists were at high risk group in terms of COVID-19 (98.5%). When clinical questions were asked, data indicatedstrong relationship between participantsâ€™ responses with their level of study. Upon asking COVID-19 specific questions, participants that have taken microbiology course were reported to have higher correct answer rate.

Dental students studying in Cyprus demonstrated high awareness of COVID-19 and the higher risks of COVID-19 exposure that dental professionals face. Study demonstrated the importance of microbiology courses, as it significantly affected the answers to the questions on diagnosis methods and immune response to COVID-19.

Published: November 2020

Objective: In this study, we aimed to evaluate CD3, T-bet and GATA3 staining of intraepithelial lymphocytes (IELs) in comparison to the routine H&E stains in celiac disease.

Methods: a total of 50 patients, in whom celiac disease was diagnosed based on a combination of clinicopathological features, were enrolled in the study. Duodenal biopsied tissues were processed routinely into formalin fixed paraffin embedded (FFPE) blocks. Sections were prepared and stained with H&E and each of CD3, T-bet and GATA3. A number of histological criteria were measured to calculate the Marsh score. The results were analyzed using the IBM SPSS analytic software.

Results: a positive correlation was found between the count of T-bet stained cells and the increase of intraepithelial lymphocytes (P-value = 0.001). In addition, low count of GATA3 stained cells was seen in almost all cases. The count of GATA3 stained cells was not affected by the increase in IELs count.

Conclusions: the majority of increased IELs were stained with T-bet. Whereas in normal IELs count is less than half the IELs were stained with T-bet. This would indicate that T-bet immunostaining is a potential alternative to H&E and/or CD3 based counting of IELs.

Dear Editor-in-Cheif

As the Coronavirus pandemic exacerbates, its disproportionate impacts affects all aspects of the community and life. The dental schools and dentistry profession were in the front line of this changes and bear a large portion of this crisis.[1] This burdens added to the dental education in Iraq in addition to its current challenges. [2,3] Until October 28th 2020, Iraq registered  463,951 cases, and 10,770 persons died from COVID-19, which 2.3% from the infected cases and 6% of the death cases were dentists.[4] Upon on the WHO recommendations along with this high mortality rate made the policy makers in Iraqi MOH and MOHESR take the decisions for national wide lockdown and closure of dental schools in Iraq and minimize the dentists presence in public hospitals and dental centers to 25%, and just for emergency patients need since March 1st 2020. This decision affected the 5th stage students which had already graduate in September 2020 from taking the enough clinical training and patient management, while the successful e-learning coverage the theoretical educational sessions well. As its impossible to certain the end of this pandemic and this will be a real threaten for the new graduated dentists skills and knowledge to manage patients, the policy makers must change the dental education program in Iraq and to add the (Exit Interview) for all graduated students which would make a need assessment for the real need, and design an intensive course for them upon on their needs that would help dental schools and educators to ensure the dental education quality assurance. This intensive course could be like the General Practice Residency (GPR) which is accredited in USA.[5] This model could be considered in other effected countries which has the same lockdown and closed policy like Iraq.

Authors: Wijaya Andik Nur , Roki'ah Siti
Published: November 2020

This study explored critical thinking skills toward YouTube resources in students' argumentative texts. The study was conducted at two non-English majors of the universities in the Indonesian context. The data were in the argumentative forms that were constructed by selected students. This study used a content analysis approach that was involved in coding and categorizing to analyze the data. After the data were analyzed, the findings showed that the patterns of critical thinking elements of the student's argumentative texts were varied, and the integration of technology resources was able to foster critical thinking skills. However, it is based upon the quality of the technology itself and the instruction in the classroom. Thus, technology implementation, YouTube resources should be found on the quality of the resources and teaching in the school.
Los muiscas en las crónicas y los archivos
Authors: Londoño L Eduardo
Published: November 2020

Para dar una imagen de las sociedades y culturas aborígenes de América, la ethohistoria ha utilizado tradicionalmente la información escrita de las crónicas de las Indias, recurriendo más recientemente a los documentos de los archivos civiles y penales del período colonial. Tomando tres ejemplos, este artículo muestra que puede existir una variación considerable en la información derivada de estas diferentes fuentes para un caso particular. Todo análisis se basará en los conceptos desarrollados por la antropología, teniendo en cuenta las circunstancias en que se produjo cada documento . Pero también es conveniente buscar otros métodos por los que nuestra investigación pueda trascender el análisis textual (literatura) para llegar a los propios indios (etnografía).

Published: November 2020

El saqueo intensivo ha descubierto un rico y variado conjunto de objetos de oro, cerámica y otros materiales de la hacienda Malagana, cerca de Palmira (Departamento del Valle del Cauca) en el fondo del valle plano del río Cauca. Estos objetos descontextualizados tienen a menudo paralelos con los objetos de los complejos culturales del sur oeste de Colombia que datan del primer milenio D.C., y especialmente con Tierradentro y San Agustín. Los vínculos más cercanos parecen haber sido con Calima (llama y Yotoco).

The Visualization, Interaction and Simulation Laboratory (VISLab) is part of the Computer Graphics, Image Processing and Interaction research group, which started its activities in 1978 developing projects mainly on rendering and animation. Along the years, as new researchers joined the group, new research fields such as image acquisition and analysis, virtual reality, non-conventional interaction, and visualization of complex data started to be investigated. Within this group, VISLab is majorly concerned with research on human-computer interaction, with emphasis on non-conventional, 3D interaction and haptics, and immersive visualization in the context of virtual and augmented reality applications. In this paper, we present the research of the VISLab and the strategy being used to achieve its main goal: to enhance the human with computers, extending the perception capabilities and improving the human power of action in a natural way.
Valuing Unpaid Care Work in Bhutan
Authors: Suh Jooyeoun , Dorji Changa , Mercer-Blackman Valerie , Hampel-Milagrosa Aimee
Published: November 2020

A growing body of scholarly literature has attempted to measure and value unpaid care work in various countries, but perhaps only the government statistical agencies in the United States and the United Kingdom have seriously undertaken periodic and systematic measures of the time spent on unpaid work at the national level, and partially incorporated those values into their gross domestic product(GDP). One country that has been ahead of its time on aspects of societal welfare measurement is Bhutan, which produces the Gross National Happiness (GNH) Index. However, until the first GNH Survey, in 2008, Bhutan did not have any sense of the size and distribution of unpaid work, despite its strong societal norms about the value of volunteering and community work. This paper is the first to estimate the value of unpaid care work in Bhutan. It shows the pros and cons of various approaches and their equivalent measures of unpaid care work as a share of GDP. As with similar studies on the topic, this paper also finds that women spend more than twice as much time as men performing unpaid care work, regardless of their income, age, residency, or number of people in the household. The paper also provides recommendations for improving the measurement of unpaid care work in Bhutan.

Authors: Ghazali Norliza , Nordin Mohamad Sahari , Abdullah Arnida , Mohd Ayub Ahmad Fauzi
Published: November 2020

This research explored two important constructs in 21st century e-education—students’ MOOC-efficacy and meaningful learning among undergraduate students in selected public universities in Malaysia. Its main objective was to examine the causal relationship of students’ MOOC-efficacy on meaningful learning. The study conceptualized students’ MOOC-efficacy in four dimensions (i.e. information searching, making queries, MOOC learning, and MOOC usability), while conceiving meaningful learning as having five dimensions (i.e. cooperative learning, active learning, authentic learning, constructive learning, and intentional learning). This research applied cross-sectional survey design. Data were collected with a 52-item questionnaire whose reliability indexes ranged from 0.822 to 0.890 for the dimensions. The study's population was identified as university students who have had some experience with MOOCs and who willingly volunteered to participate in the research. A sample of 603 respondents was drawn through simple random sampling. The full-fledged Structural Equation Modeling (SEM) was adopted for data analysis. The finding indicated that students’ MOOC-efficacy was positively associated with meaningful learning. The results show that students’ MOOC-efficacy explains 67% of the variance in meaningful learning. The fit indices indicate an adequate fit: RMSEA = 0.041, CFI = 0.923 and χ2/df = 2.067. The finding provides further insights into what works in an open online environment. The insights may be used to fulfill learners’ needs and preferences. MOOC-efficacy interventions are crucial in order to encourage students’ meaningful learning in the e-learning platform.

Filipino Teachers' Compartmentalization Ability, Emotional Intelligence, and Teaching Performance
Authors: Go Marivel Bayona , Golbin Jr. Rodolfo A , Velos Severina , Bate Glynne
Published: November 2020

Teachers, as individuals outside the classroom, deals with their problems yet are still expected to display desirable dispositions during student interaction. Thus, the strategy for regulating thoughts and emotions is vital for effective teaching. This study aims to measure Filipino teachers' problem compartmentalization ability, their level of emotional intelligence, and teaching performance, mainly when they experienced personal issues. It also seeks to determine the relationship among variables. Validated researcher-made and adopted instruments were administered to the 140 teachers from different public schools in the Cebu province, Philippines. The tools were subjected to validity and reliability tests. The gathered data were analyzed using the weighted mean and Spearman rho coefficient. Findings revealed that Filipino teachers have a high ability to compartmentalize their problems. Also, they have a high level of perceiving, understanding, managing, and using their emotions. They also display positive disposition when they are in the classroom showing their good performance despite their personal issues. Statistically, Filipino teachers' emotional intelligence and their problem compartmentalization ability were positively and significantly correlated to their teaching performance. Hence these approaches may be included by the school leaders in teachers' training for the improvement of their well-being.
POLITIK REPRESENTASI ISLAM DALAM FILM 212 THE POWER OF LOVE
Authors: Sahid Asep Abdul
Published: November 2020

Film merupakan media yang menggambarkan praktik wacana melalui penanaman kekuasaan dan ideologi. Oleh karena itu, film selalu berada dalam ruang persaingan praktik pendefinisian, pemosisian dan pengontrolan khalayak. Munculnya film-film religi bertema Islam di Indonesia juga tidak terlepas dari praktik wacana tersebut. Lebih dari satu dekade, film religi yang bercerita tentang Islam dan dinamikanya telah mampu memberikan warna bagi dunia perfilman dan juga bagi perkembangan Islam itu sendiri. Kajian dalam tulisan ini merupakan perluasan kajian tentang teks film yang bertujuan untuk mengidentifikasi, menganalisis dan merumuskan bagaimana Islam dalam konteks persaingan politik Indonesia direpresentasikan melalui narasi film. Korpus kajian adalah Film 212 the Power of Love yang memiliki latar belakang Aksi Bela Islam, 2 Desember 2016 (ABI). Islam yang dianalisis pada kajian ini mengkhususkan pada ekspresi keislaman tertentu, seperti sosial dan politik. Kajian ini menggunakan metode analisis wacana kritis dari Theo van Leeuwen yang menyajikan model exclusion dan inclusion. Kedua model analisis ini umumnya sama-sama mengandung potensi promosi dan marginalisasi. Kajian ini menunjukkan bahwa pertama, Film 212 the Power of Love menyajian wacana Islam apolitis vs Islam apatis. Dan kedua, dengan wacana tersebut menjadi promosi atau legitimasi bagi semua pendukung ABI dan sekaligus marginalisasi bagi kelompok masyarakat anti ABI.
“ZIKIR GEMILANG” ELITE POLITIK DI BANDA ACEH: Wacana Populis atau Kebijakan Publik?
Authors: Akmal Saiful , Darwin Rizkika Lhena , Zalikha Siti Nur
Published: November 2020

ikir publik menjadi arus baru di Aceh setelah tsunami. Dalam perkembangannya, zikir digunakan oleh elit politik baik ketika pilkada sebagai strategi kampanye, maupun sebagai kebijakan populis dalam menjalankan pemerintahan. Begitu pula Pemerintah Kota Banda Aceh periode 2017-2022 yang menjadikan zikir sebagai salah satu program utama yang kemudian diberi nama “zikir gemilang“. Penelitian ini tertarik untuk melihat implementasi zikir ini apakah cenderung sebagai wacana populis atau kebijakan publik. Penelitian ini menggunakan pendekatan kualitatif lewat metode wawancara semi struktur dan bola salju terhadap sejumlah informan kunci. Hasil penelitian ini menunjukkan bahwa meskipun pemahaman ulang terhadap fenomena zikir dari wacana ke aksi terjadi, namun itu sebatas pergantian slogan dari “madani“ ke “gemilang“.  Kemudian, ada tiga dimensi wacana dominan yang dimainkan oleh elit terkait pelaksanaan kebijakan zikir: 1) wacana dimensi sosial budaya (islam sebagai sistem sosial), 2) wacana dimensi ekonomi (wisata islami) dan 3) wacana dimensi politik (kebijakan populis demi elektabilitas). Penelitian ini juga mengindikasikan bahwa program zikir cenderung menjadi wacana populis untuk membentuk citra elit. Dengan demikian, kebijakan zikir digunakan sebagai pemenuhan janji kampanye, dan sarana komunikasi atau klarifikasi publik terhadap kebijakan-kebijakan yang dibuat oleh pemerintah.
Onomatopoeia in Omani Arabic
Authors: Jahdhami Said al
Published: November 2020

Onomatopoeia is believed to be of a widespread occurrence in all languages of the world though with different extents. Arabic language is attested to be rich in the use of onomatopoeia in speech, prose, and poetry. Omani Arabic, a unique variety of vernacular Arabic spoken in the Sultanate of Oman in the eastsouthern part of Arabia, likewise has numerous usages of onomatopoeic words in everyday life interactions. Both lexical and non-lexical onomatopoeia exist in Omani Arabic falling into three main categories: human sounds, animal sounds, and sounds associated with nature and objects. Onomatopoeic sounds appear in different syllabic forms including full syllables and non-syllabic forms with one or more consonants. The use of voiceless sounds and fricatives is more prevalent compared to other types of sounds.  Cases are attested of sounds captured in diverse manners exhibiting alternation among sounds close in place of articulation as well as between emphatic sounds and their non-emphatic counterparts. The use of fricatives is used to mark the duration of sounds as opposed to the use of plosives employed to show abruptness and short duration of sounds. Morphologically, most of these words are used as verbs and derivative nouns. Reduplication is likewise used to mark the intensity and duration of actions signified by these sounds.

RB137 and RB138 antibodies recognize human cathelicidin LL37 by ELISA
Authors: Palazzo Raffaella , Pietraforte Immacolata , Chizzolini Carlo , Lande Roberto , Frasca Loredana
Published: November 2020

LL37 is a cationic antimicrobial peptide (AMP), which can undergo post-translational modifications (PTM), such as citrullination and carbamylation. We demonstrate here that recombinant antibodies RB137 and RB138 are specific for native LL37 and do not recognize modified LL37 (citrullinated and carbamylated). They thus represent tools to assess the presence of native, unmodified LL37 in body fluids by ELISA.

U ovom radu izvršeno je eksperi­mentalno zavarivanje MAG postupkom zavarivanja pod­ržano ultrazvukom. Uzorci zavareni različitim para­metrima su ispitani metalografski i ispitivana je mikro­tvrdoća. Pokazano je da ultrazvučna obrada utiče na eliminaciju stubaste strukture, karakteristične za elektro­lučne postupke zavarivanja. Pored toga, javlja se smanjenje sadržaja Vidmanštetenovog i alotriomorfnog ferita, a povećanje sadržaja igličastog ferita. Kao pos­ledica, javlja se povećanje mikrotvrdoće u metalu šava. Pored toga, smanjuje se razugljeničenje na površini, što sve ukazuje da je brzina kristalizacije uz prisustvo ultrazvuka povećana u odnosu na konvencionalno MAG zavarivanje.

Southwest Borderland Voices and Stories: Community Cultural Wealth as Living Literacies
Authors: Henderson Violet
Published: November 2020

This study qualitatively examines the literacy experiences of three Southwest Borderland Latinos who left high school before graduating. Addressing a gap in the literature that reveals the limited attention paid to how students who left high school before graduating generate and use community cultural wealth (Burciaga & Erbstein, 2012), this investigation explores the vibrant role and contribution of community cultural wealth in literacy development. Through the frameworks of New Literacy Studies (NLS) and family literacy within the context of the Southwest Borderlands, and employing the tool of counternarratives through a Latino Critical Race Theory (LatCrit) lens, this study provides a platform for validating and affirming the voices, stories, experiences, and knowledges of the research participants. Utilizing portraiture as the methodology illuminates the living literacies that transpired when the participants read their world and the word (Freire, 2006).
The Underachievement of Portuguese-Canadian Youth: An Ongoing Phenomenon
Authors: Nunes Fernando
Published: November 2020

For nearly 4 generations, the youth of the Portuguese-Canadian community have been underachieving academically and dropping out of school earlier and in greater numbers, than most other youth. As a result, the Portuguese in Canada have had disproportionately low levels of frequency in post-secondary education, which are often comparable to those of Canada’s Aboriginals. The author discusses some of the reasons for the perpetuation of this phenomenon: The ignoring of the underachievement of Luso-Canadians by anti-racism education scholars; the dismissal of existing research data and unwillingness to acknowledge the effects of systemic barriers, by the community’s own political and business leadership; the belief amongst many that Portuguese-Canadian parents are at fault for the perpetuation of underachievement; the positioning of the Portuguese-Canadian community as a working-class, little-educated group; as well as a lack of programs that are specifically targeted to Portuguese-Canadian youth.
Long-term Object Tracking Based on Improved Continuously Adaptive Mean Shift Algorithm
Authors:   School of Information and Control Engineering, China University of Mining and Technology, Xuzhou 221008, China, Sun Jinping , Ding Enjie , Li Dan , Akram Adeel , Kerns Matthew Keith
Published: November 2020

Long-term object tracking encounters complex scene changes, such as deformation, short-term departure from sight, occlusion, and lighting changes, resulting in complex and unstable tracking. To improve the accuracy and success rate of long-term object tracking in complex scenes, an improved continuously adaptive mean shift (CAMShift) algorithm was proposed. The joint probability density distribution of the target model was obtained by using the Bhattacharrya coefficient to calculate the contribution of the color features and texture features. Combining with the fused target model and Kalman filter, the target position was obtained by implementing CAMShift algorithm. Finally, a template pool was designed to store high-confidence tracking results. The target template was updated online by retrieving the initial frame from the template pool to recover re-detection after tracking drift or failure. The accuracy of the proposed algorithm was verified by simulation analysis. Results show that the distance precision and success rate of the proposed algorithm are 0.9 and 0.83, respectively. The proposed algorithm effectively solves long-term target tracking problems affected by complex scenes, such as occlusion, similar colors, and deformation. This study provides references for the automatic detection of traffic incidents in the intelligent traffic monitoring system.
A Methodology for the Estimation of Microplastic Concentration in Relation to the Meteorological Forcing and WWTPs Effluents in Urban Coastal Areas
Authors:   Department of Environmental Engineering, Democritus University of Thrace, Xanthi, 67100, Greece, Anastasiou S.
Published: November 2020

The study of the urban coastline is of great significance for understanding the impacts of human activities on the marine environment. Only recently the emission of microplastics is starting to be considered as a threat to aquatic and terrestrial ecosystems and currently, little information on this topic is available. The present study focuses on the development of a methodology based on the implementation of the hydrodynamic circulation model ELCOM (Estuary and Lake Computer Model) for the estimation of microplastics distribution in Kavala Gulf coastline. The approach aims to include the effects of the high seasonal touristic activity and consequent large fluctuations in wastewater treatment plants (WWTPs) discharge rates. Parameters such as microplastic concentration, effluent flow rate and temperature, meteorological forcing and scalars at the boundaries were applied and the simulation was designed to cover the entire 2006 in order to include an approximation of the seasonal 3D dispersion patterns. The microplastic concentration was estimated based on the suspended particulate matter (SPM) concentration measurements applying the approach of [1]. The physical and chemical parameters of the particles were assumed to conform with the assumptions of [2]. The results showed a strong correlation between the microplastics dispersion patterns, the wind climate and the seasonal increase in population during the summer. Microplastic concentrations reached up to 0.185 μg/l in the WWTPs adjacent coastline in correspondence to the beaches with the highest touristic activity. The periodical formation of anticyclonic flows resulted in a net transport towards the center of the gulf and an increase in microplastic concentration in the bottom layer. On the other hand, the simulation showed that considerable quantities of microplastics tend to be transported outside the study area and far from the coastline in deeper waters.

In the experimental calibration processes, several error of measure can be obtained. Usually, these values are called as outliers. The outliers impact in the instruments’ metrological reliability and, consequently, in the industrial processes’ quality control. In specific terms, for mass metrology, the outliers are extremely critic, due to sensibility of technology used for this industry, i.e.: non-automatic weighing instruments (scales). The EURAMET/cg-18/v.02 is the international standard that defined procedure and tests for to assessment the metrological reliability of scales, however, a statistical treatment for outliers is not defined. In order to propose robust alternatives for outliers analyses, this work to evaluate parametric techniques for the elimination of outliers in the calibration of a Bernalo non-automatic weighing instruments (Capacity: 30.000 kg; Resolution: 0.001 kg). Three methods were applied in the analysis of experimental data: Dixon, Grubbs and Chauvenet. The results confirmed a reduction in the expanded uncertainty associated to mass measurement (k=2) up to: 17.6% (Dixon); 19.9% (Grubbs) and 35.2% (Chauvenet). According to the results and considering the contribution of work to applied mass metrology, the authors propose the inclusion of analyzes and evaluation of outliers in the EURAMET/cg-18/v.02. Thus, it is expected an increase in metrological reliability in mass measurement processes at the scientific and industrial sector.
Influence of Lateral Monotonic Loading Upon the Behaviour of Rubberized Concrete Filled Steel Tube

Published: November 2020

Using waste tyres as recycle material in the construction industry seems to be a good solution to the problem of waste management and landfill. The main purpose of this paper is to study the behaviour of rubberized concrete-filled steel tube (RuCFST) analytically for square and rectangular columns under lateral monotonic loading. Seventy-two prototypes modelled using ABAQUS 6.12-1 software with various variables, which are cross-section shape, rubber replacement as a percentage of natural aggregate, column length, sections slenderness ratio and the axial loading level. The results showed that the adopted model in elastic and plastic properties gives a good agreement between numerical and referenced experimental results. Moreover, increasing the rubber replacement percentage has no major effect on the columns’ capacity; meanwhile increasing the columns’ length lead to decrease the strength capacity dramatically. Furthermore, increasing the axial loading percentage leads to reduce the column lateral strength. Similarly, the columns’ capacity decreases with increasing the section slenderness ratio.
