Leveraging Text Mining Approach to Identify What People Want to Know About Mental Disorders from Online Inquiry Platforms (Preprint)
Authors: Sim Jin-Ah , Park Soowon
Published: July 2021

BACKGROUND

Online inquiry platforms, which is where a person can anonymously ask questions, have become an important information source for those who are concerned about social stigma and discrimination that follow mental disorders. Therefore, examining what people inquire about regarding mental disorders would be useful when designing educational programs for communities.

OBJECTIVE

The present study aimed to examine the contents of the queries regarding mental disorders that were posted on online inquiry platforms.

METHODS

A total of 4,714 relevant queries from the two major online inquiry platforms were collected. We computed word frequencies, centralities, and latent Dirichlet allocation (LDA) topic modeling.

RESULTS

The words like symptom, hospital and treatment ranked as the most frequently used words, and the word my appeared to have the highest centrality. Results: Four topics exist according to the LDA, which are 1) understanding general symptoms, 2) disability grading system and welfare entitlement, 3) stressful life events, and (4) social adaptation with mental disorders.

CONCLUSIONS

People are interested in practical information concerning mental disorders, such as social benefits, social adaptation, and more general information about the symptoms and the treatments. Our findings suggest that instructions encompassing different scopes of information are needed when developing educational programs.

Quantum e cosmos (Quantum and cosmos)
Authors: Novello Mario
Published: July 2021

As leis rígidas que a física produziu nesses últimos quatrocentos anos e que permitiram organizar um universo ordeiro e regular estão sendo substituídas por leis cósmicas variáveis, dependentes do tempo cósmico. A violação do determinismo tradicional produzido por processos de bifurcação descobertas no século 20 em laboratórios terrestres foram estendidas para o universo e exibiram uma situação inesperada: um cosmos hesitante. No entanto, além dessas estranhas e inesperadas novidades que alteraram profundamente o papel da ciência no imaginário do filósofo, a mais fantástica novidade veio de uma releitura atualizada de Giordano Bruno através da imagem de um universo solidário. Nesse texto farei um sobrevoo dessas questões para atrair o leitor a voos futuros que a cosmologia pode permitir. Dito de outro modo, iremos tratar do microcosmo e suas múltiplas aparências; da distinção sombria entre o real e o virtual; dos múltiplos tempos da física e do tempo único da cosmologia; da dependência cósmica das leis físicas. Daremos então um salto no vazio e mesmo além; veremos o significado do processo de bifurcação exibido por um cosmos indeciso que limita o determinismo. Finalmente exibiremos o mecanismo descoberto pelos cosmólogos de um universo cíclico que produz processos em repetição e as diferenças que ocorrem em vários ciclos. Chegamos enfim ao universo solidário antecipado por Giordano Bruno e a construção de uma ética a partir dele.
pgHMA: Application of the Heteroduplex Mobility Assay Analysis in Phylogenetics and Population Genetics
Authors: Li Teng , Wong Thomas , Ranjard Louis , Rodrigo Allen
Published: July 2021

The Heteroduplex mobility assay (HMA) has proven to be a robust tool for
the detection of genetic variation. Here, we describe a simple and rapid
application of the HMA by microfluidic capillary electrophoresis, for
phylogenetics and population genetic analyses (pgHMA). We show how
commonly applied techniques in phylogenetics and population genetics
have equivalents with pgHMA: phylogenetic reconstruction with
bootstrapping, skyline plots, and mismatch distribution analysis. We
assess the performance and accuracy of pgHMA by comparing the results
obtained against those obtained using standard methods of analyses
applied to sequencing data. The resulting comparisons demonstrate that:
(1) there is a significant linear relationship (R = 0.992)
between heteroduplex mobility and genetic distance; (2) phylogenetic
trees obtained by HMA and nucleotide sequences present nearly identical
topologies; (3) clades with high pgHMA parametric bootstrap support also
have high bootstrap support on nucleotide phylogenies; (4) skyline plots
estimated from the UPGMA trees of HMA and Bayesian trees of nucleotide
data reveal similar trends, especially for the median trend estimate of
effective population size; and (5) optimized mismatch distributions of
HMA are closely fitted to the mismatch distributions of nucleotide
sequences. In summary, pgHMA is an easily-applied method for
approximating phylogenetic diversity and population trends. KEYWORDS:
bootstrap, heteroduplex mobility assay, mismatch distribution,
phylogenetics, skyline plot
Various parameters of the multiaxial variable amplitude loading and their effect on fatigue life and fatigue life computation
Authors: Papuga J. , Margetin Matúš , Chmelko Vladimír
Published: July 2021

The paper discusses various partial solutions used for estimating
fatigue life under variable amplitude multiaxial loading in the
high-cycle fatigue domain. The concurring effects are treated, and their
proposed solutions are commented upon. The major focus is on the
categories of the phase shift effect and of cycle counting, and on the
scope and quality of data, which support discussed theories. Results of
own new experimental data set on specimens from S355 steel are provided.
Fatigue life estimates for McDiarmid and Findley multiaxial methods and
for two different methods of load path decomposition to cycles are shown
to highlight some of the points open for discussion. It is concluded
that the available experimental data are not sufficient to substantiate
a clear decision to follow a definite algorithm.

Published: July 2021

Introduction Pre-operative management of neonates with esophageal
atresia and tracheoesophageal fistula (EA/TEF) requiring positive
pressure ventilation (PPV) support is clinically challenging. This study
evaluates the safety, feasibility and value of flexible endoscopy with
noninvasive ventilation and sustained pharyngeal inflation (FE-NIV-SPI)
in diagnosis and placing a naso-tracheo-fistula-gastric (NTFG) tube
before surgery. Methods A retrospective study conducted from 2017 to
2020 in neonates with Type-C EA/TEF and respiratory distress, where
FE-NIV-SPI performed with NTFG tube placement before surgery. Results
Five neonates were collected, one with duodenal atresia and one with
transposition of great artery. At FE-NIV-SPI, median body weight was
2,399 g and mean age was 15.2 hours. Four neonates yielded severe
(>80% collapsed) tracheomalacia. With this FE-NIV, all
tracheal, fistulas and esophageal lumens could clearly assess and
manage. All fistulas were less than 8mm proximal to carina with mean
orifice width of 5 mm. All NTFG tubes placed successfully after
confirmed the EA/TEF. Three neonates had co-intubated with nasal
endotracheal tube and 2 neonates had received nasal prongs PPV. Mean
procedural time of FE-NIV was 13.6±4.5 minutes. All neonates received
gastric decompression and feeding via NTFG tubes for mean of 11.4±18.2
days and had stable pre-surgical courses. No adverse associated
complication noted. Conclusion FE-NIV-SPI technique enables safe and
accurate measurement of EA/TEF anatomy and placing NTFG tube. It could
avert emergent gastrostomy, aid gastric decompression, feeding, and ETT
intubation, improve PPV, provide pre-surgical stabilization and identify
the fistula location during the surgical correction.
Covid-19: acquired acute porphyria?
Authors: Abrahams Lianne
Published: July 2021

Pandemic Covid-19 pneumonia, of SARS-CoV-2 aetiology, is of global importance to health systems, national economies, and individual civil liberties. Multiple therapeutic and prophylactic agents are currently undergoing clinical trial and, while progress towards a curative agent is promising, the principal limiting factor in public health emergency is time. A pre-existing licensed therapeutic would offer reprieve to international citizens currently enduring the adverse consequences of lockdown policies. The current review advances the author’s original hypothesis and advocates direct testing of the hypothesis by urinalysis of light-protected samples from critical Covid-19 patients to check for elevated aminolevulinic acid and porphobilinogen.

Published: July 2021

El cultivo de piña tiene una alta producción en Latinoamérica y ha incrementado su producción en los últimos años en países como Uruguay, Brasil, Ecuador, Costa Rica y Colombia, de la mano de procesos de desarrollo social, lo que ha logrado beneficiar a muchos agricultores. Este experimento se realizó en San Martin, Meta, Colombia, donde fue sembrada la piña variedad MD2 en distancias de 30 cm entre plantas por 40 cm entre líneas en cama y de un metro entre camas; se realizó evaluación de dos metodologías de aplicación: T1 = fertilización dirigida al suelo, T2 = fertilizante aplicado en la axila de la planta, ambos casos con dosis exacta; y se compararon con un testigo (T3) en donde no se aplicó ningún fertilizante. En este proyecto se estableció un diseño en bloques completos al azar, con tres tratamientos y cinco repeticiones, cada repetición estuvo constituida por 120 plantas por cama (600 plantas por tratamiento), que correspondió a una unidad experimental, evaluando cada 15 días (15, 30. 45 y 60 días) cinco plantas/cama/repetición, bajo un análisis de varianza con prueba de comparación de Duncan. A los 15 y 30 días de evaluación T1 y T2 presentaron las mayores de alturas de la planta (P<0.05) con valores de 15.18 y 43.60. y 16.24 y 53.20 cm respectivamente, en comparación con el testigo T3 (13.93 y 39.44 cm). A los 45 y 60 días T2 mostró una altura superior (P<0.05) con valores de 77.90 y 94.66 cm en comparación con T1 66.52 y 88.30; y T3 68.26 y 79.90 cm respectivamente; aunque a los 45 días T1 y T3 mostraron un comportamiento similar (P>0.05). Según los métodos de fertilización evaluados, el de aplicación directa al suelo evidenció mejor respuesta por parte de la planta en su sistema radicular y foliar, en comparación con los tratamientos de fertilización axilar y sin aplicación de productos (testigo), puesto que las plantas sometidas a fertilización directa en el suelo (T2) presentaron características de desarrollo más eficientes para la absorción de nutrientes.

The use various branches of transport on the grain market in Ukraine
Authors: Cherevko Heorhiy , Kolodiichuk Volodymyr
Published: July 2021

The purpose of the article is to assess the transport potential of the logistic supply of the grain market. In the article, on the basis of the dialectical method of cognition of objective reality and using the comparison technique, the logistic characteristics of railway, automobile, sea and river transport in transportation of grain cargoes in Ukraine are considered. It was determined that the weakest link in railway is the lack of grain wagons, their insufficient technical condition and a low level of rolling stock. That in turn limits the options of other elements of logistics system. The average annual rail route shipment of grain in Ukraine makes only 11% as opposed to 95% in the USA, for example. It leads to increased logistics costs and reduces the duration of grain wagons turnover. Ukraine has favorable conditions and a big potential for marine and river transport but unfortunately it is not used properly. It was established that the problematic issues of automobile shipment are the bad condition of roads. They do not meet international quality standards, and the average speed on the roads is several times lower than in Western European countries. The worst situation is in the rural areas that significantly complicates the logistics system and transporting grain from fields to elevators.

Nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH) are common conditions with a rising burden. Yet there are significant management gaps between clinical guidelines and practice in patients with NAFLD and NASH. Further, there is no single global guiding strategy for the management of NAFLD and NASH. The American Gastroenterological Association, in collaboration with 7 professional associations, convened an international conference comprising 32 experts in gastroenterology, hepatology, endocrinology, and primary care providers from the United States, Europe, Asia, and Australia. Conference content was informed by the results of a national NASH Needs Assessment Survey. The participants reviewed and discussed published literature on global burden, screening, risk stratification, diagnosis, and management of individuals with NAFLD, including those with NASH. Participants identified promising approaches for clinical practice and prepared a comprehensive, unified strategy for primary care providers and relevant specialists encompassing the full spectrum of NAFLD/NASH care. They also identified specific high-yield targets for clinical research and called for a unified, international public health response to NAFLD and NASH.

Published: July 2021

In this research, the damage mechanism applied by the projectile at the ballistic tip on the samples during the ballistic test of the samples consisting of different materials with the same wall thickness as the ballistic test was attempted to determine. Free falling low velocity ballistic test was performed in order to compare stainless steel, brass, copper, low carbon steel materials with the same wall thickness section. A jig consisting of sensitive force readings was set up and its principles were established. This study showed that the projectile tip creates a deformation zone as well as the state of absorbing the impact on the material which are possible to determine by sensitive measurements. Stainless steel and Brass showed better performance than low C steel and Copper due possibly to low work hardening property. K, strength coefficient, showed a significant correlation with the results.

Examining Saudi EFL University Students’ Readiness for Online Learning at the Onset of Covid-19 Pandemic
Authors: Abdullah Ghobain Elham , Ahmed Zughaibi Abdullah
Published: July 2021

Nowadays, especially after the COVID-19 crisis lockdown, the heavy reliance on technology and online platforms led to a greater expectation of more learning autonomy among English learners in EFL contexts such as Saudi Arabia. The sudden shift to online learning requires an investigation into students’ readiness and willingness for such a mode of learning. This can provide educators with many prospects about learning outcomes achievement and assessment, test performance, and interaction during classes. Therefore, the current study seeks to contribute to the well-known area of learner autonomy research, which is still lacking in the context of the study, by exploring the readiness of Saudi first-year undergraduate English learners towards online education. Participants’ level of readiness is identified according to their autonomous behaviors and activities. The study will also assess the investigated concept considering the influence of gender and field of study of the participants on their autonomy levels. A total of 802 students participated in this study. It was found that Saudi first-year university students are moderately autonomous, that both males and females have similar levels of aptitude and readiness for taking responsibility for their learning, and that English-major and non-English-major groups showed comparatively similar levels across different learning autonomy dimensions. Yet interestingly, English-major participants displayed a relatively lower autonomy level than students of other majors.

Modern Information and Communication Technologies have provided the mastery of writing skills by philology students during distance learning. Writing skills are acquired in writing texts of different genres: primary, written without the resource literature, and secondary, written by students based on primary sources. Interactive activities based on Internet resources enabled creating a virtual learning environment for mastering the second language written communication. This study analyzes various interactive activities on the Internet and suggests division into two groups: educational and controlling interactive activities. The study aims to define the effectiveness and methodological characteristics of the interactive activities to optimize the writing skills mastering during lockdowns. It presents the stages of text writing for users of the A2 language level. The paper gives examples of interactive activities based on communicative situations that teach to write a text at a sentence, paragraph, and text level. It also determines their goal, techniques, ways of control, and benefits of using such exercises for self-study of writing skills. The study concludes with recommendations of using communicative cases and activities to improve mastering written communication.

Authors: Alsuhaibani Zainab
Published: July 2021

Online learning becomes the means of education during COVID-19. Blackboard is one of the learning management systems that has been widely used before and during the pandemic. This study focuses on English as a Foreign Language (EFL) students’ use and perceptions of Blackboard. It explores and compares EFL students’ use and perceptions of Blackboard considering three phases: before COVID-19 in 2019, during online learning in 2020, and during online learning in 2021. A questionnaire and semi-structured interviews were used to collect the data. A total of 381 Saudi EFL students participated in the study. The results show that there are statistically significant differences in EFL students’ use of Blackboard between the three phases. EFL students’ use of Blackboard increased during online learning in 2020 compared to 2019, especially concerning the frequency of visiting Blackboard and the time students spent using it. Further, EFL students’ use of Blackboard increased significantly during online learning in 2021 compared to 2019 with regard to visit frequencies, time spent, and Blackboard tools used. Considering perceptions, the results indicate that there are statistically significant differences in students’ perceptions of Blackboard in terms of easiness and usefulness between the three phases. Interestingly, students had more positive perceptions of Blackboard before COVID-19 in 2019 and during online learning in 2021. The technical problems that students faced while using Blackboard during 2020 might have affected their perceptions. The study results of students’ use and perceptions of Blackboard are discussed in light of institutional policies and support.

The present paper aims to examine the use of the persuasive rules in texts and images to determine the role of these visual modes in recalling or adding what they mention. Such a study helps set clearly which visual mode is much more convincing, the image or the text. Scholars generally agreed that the visual mode is more persuasive. However, such a statement is general as it does not state exactly which type of visual mode is more convincing. Accordingly, the research questions highlighted here are: What are the persuasive strategies invested in any of these two visual modes, texts and images? And, what is the role these visual modes play to enhance the sense of persuasion? To achieve the objectives, the researchers will adopt the cognitive linguistic theory of frame semantics by Fillmore (1995). Since the study is qualitative, the study’s data will be limited to four randomly selected American English advertisements posted on Facebook. Findings have revealed that the number of the evoked frame units is unlimited and subjective, reflecting, as a result, a person’s imagination power, his needs, and desires. The study has concluded that the visual, written text is more persuasive than the pictures and photos. The text reflects a bricolage of various persuasive strategies that help pull the attention. Besides, the images provided played a vital role, though secondary to the texts, supporting the textual information and flavor it realistically.

Published: July 2021

The global spread of the COVID-19 pandemic has caused one of the most extensive school closures worldwide, sending over one billion students home away from their schools, teachers, and classmates. Governments opted for online education to ensure the continuity of learning. Teachers in Morocco have opted for different tech tools and platforms to design and deliver online classes. This study aims to assess the impact and effectiveness of online teaching during the COVID 19 outbreak among teachers in Morocco. Based on the theoretical framework Online Collaborative Learning (OCL), an online survey questionnaire is employed as a data collection instrument. A total of 421 Moroccan teachers from different regions all over Morocco took part in the study. This paper used the Statistical Package for Social Sciences (SPSS) software to analyze the collected data and determine the impact and quality of online teaching during the Covid-19 national school closure in Morocco. The results showed that most of the teachers faced numerous technology, training, and socio-economic challenges that acted as barriers to the processes of online education. The findings obtained can be of use in making future decisions concerning the implementation of teaching and learning online programs in Morocco considering the teachers’ perspective.
The Presence of Learner Identity in Online Classes in UTAS-Rustaq

Learner identity has always been a crucial aspect in shaping learners’ learning process. However, the unprecedented and inevitable shift to online learning increases the need to invest in learners’ digital identities. Virtual classes are a new learning context for many Omani students, including the University of Technology and Applied Sciences-Rustaq (UTAS-Rustaq) students, introducing them to new social norms and relatively new assigned roles. Despite students’ current presence in the virtual classes, they are not new to the virtual world; many are already part of social networks. The present study, therefore, aims to investigate learners’ participation in social media and whether such presence would have an impact on their acceptance and involvement in online learning. There is an urge to examine this area which remains unexplored in UTAS-Rustaq due to its past limited practices. A mixed-method approach was implemented to elicit data; the focus group interviews aimed to seek in-depth insights to illuminate the collected data from the survey. The participants were English language learners who have experienced online learning for almost a year. The results indicated a positive presence in the virtual world in contrast to a negative presence in the virtual classroom. Surprisingly, technical difficulties were not the reason for students’ resentment of online learning; on the contrary, students reported that they elevated their technical skills due to the current situation. Rather, negativity arose from a lack of relational connectedness with the new context, which students kept referring to as a temporary situation and lack of teachers’ support.

ABSTRACT Dentistry treatment is not only focused on restoring the function of mastication but also onthe aesthetic problem. Fluorosis is one of the aesthetic problems caused by excessive fluoride intakeduring email formation and produced color changes on the surface of the email. Fluorosis was notaffected by the aesthetics but also influenced the confidence of the patient. The Microabrasion techniqueis an option for fluorosis because it is conservative treatment with good results. A 20-year-old womanwho came to the Dental Conservation clinic complained that she wants to remove the brown color andwhite spots seen on the front teeth, which significantly interfere with her appearance. Based on clinicalexamination, many cavities were found in the back teeth of the upper and lower jaw. The results of thehistory and clinical study revealed that the patient had fluorosis in her teeth. Microabrasion was carriedout using Opalustre (ultradent). This material was applied to the tooth surface and rubbed using anapplicator (opal bristle) for 60 seconds. Then applied fluoride gel paste with finishing cup opal.Treatment results showed changes in tooth color, brown and white patches disappeared. Microabrasionis the first choice for aesthetic treatment in fluorosis and has shown satisfying results to restore thepatient's aesthetics problem. KEYWORDS: Fluorosis, microabrasion technique

ABSTRACT Diabetes Mellitus (DM) is a metabolic disorder characterized by high blood glucose levelsassociated with periodontal disease and increased levels of inflammatory biomarkers such asinterleukin. Therapeutic effects of molecular hydrogen for a wide range of disease models and humandiseases have been investigated. This review aims to systematically analyze and review animal andhuman studies investigating the effect of HRW on periodontal tissues, interleukin, or blood glucoselevels. An electronic search was conducted via PubMed/Medline, Google Scholar, Wiley Online Library,LILACS, Science.gov, and Cochrane Central Register of Controlled Trials (CONTROL) using thekeywords "Hydrogen Water", "Diabetes Mellitus", "Interleukin" and "Periodontal disease" for studiespublished between January 2011 to May 2021. After the elimination of duplicate items, the primarysearch resulted in 101 articles. After excluding irrelevant articles based on abstract and title, full texts of45 articles were read to exclude additional unrelated studies. Eight studies were included in this reviewfor qualitative analysis. The results showed that Drinking HRW exerts certain antioxidants for oxidativegingival stress and anti-inflammatory effects by decreasing interleukin and decreasing blood glucoselevels for DM patients.

Home-Based Enterprise and Its Impediment Factors to Self-Help House Improvement in Kampong Cikini, Jakarta
Authors: Adianto Joko , Gabe Rossa Turpuk
Published: July 2021

This research aims to embellish the existing literature on Home-Based Enterprise (HBE) to recuperate it as one of the effective solutions for self-help slum improvement programs in the future. Many experts have praised HBE as one of the plausible solutions for slum alleviation through income-generating activities that will enable the underprivileged to perform self-help house improvement. However, there is a vague establishment between HBE to self-help house improvement in Kampong Cikini, as one of the notable slum settlements in Central Jakarta. Through the employment of the case study method, this research established HBE’s contribution to self-help house improvement is less significant because of several impediments, which indicates the increment monthly income from HBE cannot automatically ignite the self-help house improvement. Both HBE and self-help house improvement are inseparable from socio-economy activities in the neighborhood and cannot be comprehended as an individual economy household’s activities. Therefore, specific solutions are required to overcome the mainly encountered impediments with considering the established interwoven domestic and economic activities, for increasing the impact of HBE to self-help house improvement.
