Authors: Nugrahhu Putra Andino
Published: February 2024

The purpose of this study is to see the extent to which the implementation of teaching and learning activities for Cultural Arts subjects, especially in the field of Music Arts at high schools in Palangka Raya, was carried out during the COVID-19 pandemic. This research is evaluation research with a descriptive qualitative approach that uses a discre­pancy evaluation model that measures the gaps in the learning process. Data was collec­ted through observation, interview, and documentation techniques and validated using triangulation and source triangulation. The results of the study found that in the evalua­tion of input, music art learning consisting of curriculum components, lesson implemen­tation plans, teacher qualifications, and learning facilities has run well. However, teacher qualifications and learning facilities need to be reviewed so that they can be adjusted to the standards set by the government. In the evaluation of the music art learning process consisting of teacher performance, student attitudes, class climate, and student learning motivation is in a good category, where the teacher masters the learning material and can manage to learn well, thus creating a class climate, student attitudes, and student learning motivation are in a good category. Music learning outputs are evaluated by the minimum completeness standards set in each school. Music learning programs in schools can still run well, but there needs to be an adjustment of subject teachers’ tea­ching qualifications not to produce outputs that deviate far from the main objectives of art education.

Published: February 2024

This study aimed to create a basic plan for adding bioinformatics education into STEM (Science, Technology, Engineering, and Mathematics) learning, particularly for future biology teachers. By reviewing studies from 2019 to 2023 in the ERIC Database with the key terms "Bioinformatics Education" and "STEM Literacy," the research highlighted important areas in this subject. It organized the findings into four main themes related to bioinformatics education: levels of education, challenges faced, teaching methods, and methods for research or evaluation. Additionally, it identified three themes in STEM literacy: educational levels, challenges, and definitions or ways to measure it. The review pointed out a critical need for teaching materials, tools, and strategies in bioinformatics for future biology teachers at the college level. It also found a lack of research on STEM literacy at this level, with just three articles addressing it. These articles examined STEM literacy through skills such as general knowledge, career awareness, and communication skills. The suggested basic plan promotes combining bioinformatics education with real-world biological issues, career preparation, and addressing educational shortcomings. It recommends a bioinformatics module with specific curriculum content, tools, and teaching methods to improve STEM literacy, including knowledge, attitudes, and skills in STEM. This plan could guide future research in classrooms to improve STEM literacy among future biology teachers through bioinformatics education.

Quality Assessment of Smartphone Medication Management Apps in France: Systematic Search
Authors: Toïgo Mickael , Marc Julie , Hayot Maurice , Moulis Lionel , Carbonnel Francois
Published: February 2024

Background

Adherence to medication is estimated to be around 50% for chronically ill patients in high-income countries. Improving the effectiveness of adherence interventions could have a far greater impact on population health than any improvement in specific medical treatments. Mobile health (mHealth) is one of the most effective solutions for helping patients improve their medication intake, notably through the use of mobile apps with reminder systems. With more than 327,000 apps available in the mHealth field, it is difficult for health care professionals and patients alike to choose which apps to recommend and use.

Objective

We aim to carry out a systematic search of medication management smartphone apps available in France that send reminders to patients and assess their quality using a validated scale.

Methods

Mobile apps were identified in October and November 2022 after a systematic keyword search on the 2 main app download platforms: App Store (Apple Inc) and Google Play Store. Inclusion criteria were free availability, date of last update, and availability in French. Next, 2 health care professionals independently evaluated the included apps using the French version of the Mobile App Rating Scale (MARS-F), an objective scoring system validated for assessing the overall quality of apps in the mHealth field. An intraclass correlation coefficient was calculated to determine interrater reliability.

Results

In total, 960 apps were identified and 49 were selected (25 from the App Store and 24 from the Google Play Store). Interrater reliability was excellent (intraclass correlation coefficient 0.92; 95% CI 0.87-0.95; P<.001). The average MARS-F score was 3.56 (SD 0.49) for apps on the App Store and 3.51 (SD 0.46) for those on the Google Play Store, with 10 apps scoring above 4 out of 5. Further, 2 apps were tested in at least one randomized controlled trial and showed positive results. The 2 apps with the highest ratings were Mediteo rappel de médicaments (Mediteo GmbH) and TOM rappel medicaments, pilule (Innovation6 GmbH), available on both platforms. Each app’s MARS-F score was weakly correlated with user ratings on the App Store and moderately correlated on the Google Play Store.

Conclusions

To our knowledge, this is the first study that used a validated scoring system to evaluate medication management apps that send medication reminders. The quality of the apps was heterogeneous, with only 2 having been studied in a randomized controlled trial with positive results. The evaluation of apps in real-life conditions by patients is necessary to determine their acceptability and effectiveness. Certification of apps is also essential to help health care professionals and patients identify validated apps.
Experiences and Views of Young People and Health Care Professionals of Using Social Media to Self-Manage Type 1 Diabetes Mellitus: Thematic Synthesis of Qualitative Studies (Preprint)
Authors: Ma Yanan , Law Kate , Hassan Lamiece , Nenadic Goran , van der Veer Sabine N
Published: February 2024

BACKGROUND

Social media have shown the potential to support type 1 diabetes self-management by providing informational, emotional, and peer-to-peer support. However, the perceptions of young people and health care professionals’ (HCPs) toward the use of social media for type 1 diabetes self-management have not been systematically reviewed.

OBJECTIVE

The aim of this study is to explore and summarize the experiences and views of young people with type 1 diabetes and their HCPs on using social media for self-management across qualitative findings.

METHODS

We searched MEDLINE, Embase, PsycINFO, and CINAHL from 2012 to 2023 using Medical Subject Heading terms and text words related to type 1 diabetes and social media. We screened and selected the studies according to the inclusion and exclusion criteria. We quality appraised and characterized the included studies and conducted a thematic synthesis.

RESULTS

We included 11 studies in our synthesis. A total of 9 of them were qualitative and 2 were mixed methods studies. Ten focused on young people with type 1 diabetes and 1 on HCPs. All used content analysis and were of moderate to high quality. Thirteen descriptive themes were yielded by our thematic synthesis, contributing to five analytic themes: (1) differences in how young people interact with social media, (2) characteristics of social media platforms that influence their use and uptake for type 1 diabetes self-management, (3) social media as a source of information, (4) impact on young people’s coping and emotional well-being, and (5) impact on support from and relationships with HCPs and services.

CONCLUSIONS

The synthesis suggests that we should consider leveraging social media’s peer support capabilities to augment the traditional services for young people with type 1 diabetes. However, the patients may have privacy concerns about HCPs’ involvement in their online activities. This warrants an update of existing guidelines to help young people use social media safely for self-managing their diabetes.

COVID-19 pandemic was reported to modify people’s behaviour in using public spaces and accessing services. This fact has become a critical input related to future city development strategies, space arrangements, and the implementation of smart city. Therefore, this study aims to 1) Identify efforts in several cities during COVID-19 pandemic, specifically concerning the use of public spaces and services, and 2) Compile the outlines of future urban planning strategies after the pandemic. The aspects related to the use of Information and Communication Technology (ICT), space arrangement, and urban environment are discussed. The analysis is based on case studies in four capital cities, namely Jakarta, Paris, Bucharest, and Canberra. Furthermore, field observations and in-depth interviews are used to emphasize changes in the function and use of public spaces and services during and after the pandemic. The result shows that differences and common elements configure the transformations of urban spaces since changes in the use of public spaces are closely connected to efforts to combat the pandemic. Meanwhile, in public services, changes are associated with the increasing use of ICT and Internet of Things (IoT). In the future, cities need to show their visions according to the local conditions supporting better spatial arrangement and management of urban environment due to ICT and IoT prominence.

Food loss and wastage occur in large quantities globally every year and it occurs in the entire supply chain right from the production to the processing stage. The loss of food is due to various factors like adopting traditional cultivation practices, low investment in the food sector, and more loss from poor pests and disease management of agricultural crops. The most important and major cause is due to microbial spoilage; fungi are most harmful to the consumers and also to the agriculture sector. Synthetic chemical strategies can prevent fungal growth and may reduce wastage but still causes accumulation of chemical substances in the environment and food chain in a long run. For these reasons, the use of bio-control technologies can be a great solution to agriculture and food sector as well. In view of this, the present study has been conducted using an efficient Azotobacter species, which belongs to the PGPR group. In this study, antifungal compounds produced by Azotobacter have been extracted by following solvent extraction protocols and identified using GCMS methods. The antifungal compounds were tested against the major fungal pathogens viz., Aspergillus, Fusarium, and Penicillium species. The metabolites produced by Azotobacter species were efficient in controlling the growth of the fungal species. These compounds can be used as a potential bio-preservative in the food sector instead of synthetic chemicals. Thus, these compounds can further be analyzed and tested on the food sample, having a great scope in the future to replace the chemical preservatives.

Published: February 2024

Durante las últimas décadas, la Educación ciudadana en Chile ha cobrado una especial relevancia. Esto ha quedado evidenciado a partir de la explicitación de su abordaje por medio del currículo (MINEDUC, 2012; MINEDUC, 2015; MINEDUC, 2018; MINEDUC 2019), el establecimiento de la Ley 20.911 que crea el Plan de Formación Ciudadana (MINEDUC, 2016; MINEDUC 2018 A), y de la incorporación de este ámbito en los nuevos Estándares para el desarrollo profesional docente: Marco para la Buena Enseñanza (CPEIP, 2021). Debido a este contexto, a través de la siguiente investigación nos interesa indagar en cómo una carrera de Pedagogía en Educación Primaria del Norte de Chile ha abordado la enseñanza de la Educación Ciudadana desde el punto de vista disciplinar y didáctico, y cómo este abordaje influye en las representaciones sociales que el profesorado en formación construye sobre su rol y el de la escuela en el desarrollo de competencias ciudadanas del estudiantado. La investigación se sitúa desde una perspectiva cualitativa (Ñaupas, et al, 2018), y utiliza el estudio de caso para abordar sus objetivos. Los resultados preliminares evidencian que el enfoque utilizado por la carrera ha tensionado el desarrollo de una ciudadanía con pertinencia territorial, que considera clave asumir un compromiso activo con la protección del entorno natural, social y cultural. A su vez, asignan una gran relevancia a la escuela en este proceso de generación de ciudadanía, pero reconocen tensiones en las prácticas cotidianas de esta para la promoción de una cultura democrática.
The Risk of Silence—How the Capital Market Penalizes Social Media Passivity
Authors: Beer Christian , Maniora Janine , Pott Christiane
Published: February 2024

We examine whether passivity on firms’ corporate Facebook pages moderates the relationship between the sentiment among social media users toward the firms and their future stock returns. We find that a longer period of posting passivity is likely to reverse a positive effect of positive sentiment on the firm’s future stock prices. For negative sentiment, we find that social media passivity results in amplified negative sentiment on the firm’s future stock prices. Moreover, we find that the longer the firm is passive, the longer it takes to overcome the negative effects of the posting passivity by resuming posting.

An in vitro comparison of the dimensional stability of four 3D-printed models under various storage conditions
Authors: Knode Vanessa , Ludwig Björn , Hamadeh Sinan , Pandis Nikolaos , Fleming Padhraig S.
Published: February 2024

Objectives

To investigate the dimensional stability of various 3D-printed models derived from resin and plant-based, biodegradable plastics (PLA) under specific storage conditions for a period of up to 21 weeks.

Materials and Methods

Four different printing materials, including Draft V2, study model 2, and Ortho model OD01 resins as well as PLA mineral, were evaluated over a 21-week period. Eighty 3D-printed models were divided equally into two groups, with one group stored in darkness and the other exposed to daylight. All models were stored at a constant room temperature (20°C). Measurements were taken at 7-week intervals using the Inspect 3D module in OnyxCeph software (Image Instruments GmbH, Chemnitz, Germany).

Results

Dimensional change was noted for all of the models with shrinkage of up to 0.26 mm over the study period. Most contraction occured from baseline to T1, although significant further contraction also arose from T1 to T2 (P < .001) and T1 to T3 (P < .001). More shrinkage was observed when exposed to daylight overall and for each resin type (P < .01). The least shrinkage was noted with Ortho model OD01 resin (0.16 mm, SD = 0.06), and the highest level of shrinkage was observed for Draft V2 resin (0.23 mm, SD = 0.06; P < .001).

Conclusions

Shrinkage of 3D-printed models is pervasive, arising regardless of the material used (PLA or resin) and being independent of the brand or storage conditions. Consequently, immediate utilization of 3D printing for orthodontic appliance purposes may be preferable, with prolonged storage risking the manufacture of inaccurate orthodontic retainers and appliances.

Bile acids (BAs) are pleiotropic regulators of metabolism. Elevated levels of hepatic and circulating BAs improve energy metabolism in peripheral organs, but the precise mechanisms underlying the metabolic benefits and harm still need to be fully understood. In the current study, we identified orosomucoid 2 (ORM2) as a liver-secreted hormone (i.e., hepatokine) induced by BAs and investigated its role in BA-induced metabolic improvements in mouse models of diet-induced obesity. Contrary to our expectation, under a high-fat diet (HFD), our Orm2 knockout (Orm2-KO) exhibited a lean phenotype compared with C57BL/6J control, partly due to the increased energy expenditure. However, when challenged with a HFD supplemented with cholic acid, Orm2-KO eliminated the antiobesity effect of BAs, indicating that ORM2 governs BA-induced metabolic improvements. Moreover, hepatic ORM2 overexpression partially replicated BA effects by enhancing insulin sensitivity. Mechanistically, ORM2 suppressed interferon-γ/STAT1 activities in inguinal white adipose tissue depots, forming the basis for anti-inflammatory effects of BAs and improving glucose homeostasis. In conclusion, our study provides new insights into the molecular mechanisms of BA-induced liver-adipose cross talk through ORM2 induction.

Polycystic ovary syndrome (PCOS) portrays a common which impacts the reproductive capacity as well as causes irregular menstrual cycles. Apart from criteria set at the time of Rotterdam syndrome ESHRE/ASRM-sponsored PCOS consensus, in the last decade, a newer problem insulin resistance (IR) has been observed more commonly along with subjects having PCOS greater IR in view of different for instance overweight in addition to obesity, however clarification is lacking in patients with PCOS who are of normal weight, thereby validating the posit that IR takes place independent of weight. It has been confirmed by proof that there is existence of the complicated pathophysiological conditions taking place resulting in dysfunctional post insulin receptor signalling particularly in PCOS patients having familial diabetes. Furthermore PCOS patients documented a greater incidence of non-alcoholic fatty liver disease (NAFLD) associated with hyperinsulinemia, which was observed to be greater in obese subjects having PCOS. Here in this narrative review we have concentrated on how as a further corollary to the in-depth work of the group of Genazzani AD; applications might be made with regards to utilization of very low-calorie ketogenic diet (VLCKD) along with Mediterranean diet (MD) for the treatment of PCOS apart from part of the glycaemic index in addition to glycaemic load in the generation of PCOS as well as prevention of its complications as well as trans generational transmission to the progeny.

ABSTRACT
Dental and oral health problems affect more than half of Indonesia's population (57.6%). The highest prevalence of dental caries occurs in children aged 5–9 years (92.6%). Dental caries in children can cause pain, difficulty chewing food, difficulty sleeping, and difficulty concentrating, which have an impact on children's quality of life. Prevention efforts can be done by providing dental health education. Education necessitates the use of media in its delivery. One of the media that can be used is a story book. The purpose of this community service is to increase the knowledge of elementary school students about maintaining oral health. Muhammadiyah 1 Ketelan Surakarta Elementary School provided education for 30 grade 4 students. Education was carried out using storybooks as media. The book contains material related to maintaining oral health. In the book, there are several games used as material for evaluation. The measurement of knowledge is done before and after the provision of education. The results of education showed that 25 students (83.3%) experienced an increase in knowledge, 2 students (6.7%) experienced a decrease, and 3 students (10%) had a fixed value. Conclusion: Story books can be used as educational media because they can increase children's knowledge.

In the present article, the combined influence of the changeable gravity field and temperature-reliant viscosity on the porous bed is considered for investigation numerically by the Galerkin technique in the presence of upward vertical throughflow. The temperature-reliant viscosity is known to be exponential. The porous matrix is subjected to continuous downward gravity fluctuations varying with distance across the medium and vertical upward throughflow. Four different cases of gravity variance were discussed. A parametric analysis is conducted by adjusting the following parameters: throughflow parameter, viscosity parameter, and gravity parameter. Results show that the beginning of the convective moment would be delayed by all three parameters throughflow, temperature-reliant viscosity, and gravity variance. It has been shown that the fluidic system is more inconsistent in case (iii) and more consistent in case (iv).

The study of transverse oscillations of systems moving along their axis is a very difficult, but at the same time a very important task. Mathematical models of nonlinear transverse oscillations of a beam moving along its axis are analyzed in this paper work, both for non-resonant and resonant cases. The task becomes even more complicated if we additionally take into account the method of fastening the ends of the beam or the perturbation at its ends. We have obtained dependencies that can be used in construction, transport, industry, mechanical engineering and other domains of technology, ensuring the stability and safety of the operation of such mechanical systems. Mathematical models have been obtained for structural engineers to determine the amplitude–frequency response of relevant structures. These mathematical models are key to researching the dynamics of moving media. The obtained results allow considering not only the influence of kinematic and physical-mechanical parameters on the amplitude–amplitude frequency response of the medium, but also the fastening method. In addition, the correlations obtained in the paper make it possible to study not only the influence of the moving medium parameters on the nature of changes in the frequency and amplitude of oscillations, but also to consider the movement at the points of support of the medium. Namely, even at the stage of designing a pipeline for a liquid flowing at a certain speed, it is possible to consider the influence of the oscillation of the supports or their fastening method on the dynamics of the oscillatory process. The resulting dependencies allow designers to consider the influence of the characteristics given in the paper with a high level of accuracy and predict dynamic phenomena in them. In engineering calculations of various mechanical systems, the resulting dependencies can be used to optimize parameters to avoid negative destructive phenomena during operation.

Published: February 2024

Threats to the climate and global changes in ecological processes remain an urgent problem throughout the world. Therefore, it is important to constantly monitor these changes, in particular, using non-standard approaches. This task can be implemented on the basis of research on bird migration information. One of the effective methods of studying bird migration is the auditory method, which needs improvement. That is why building a model based on machine learning methods that will help to accurately identify the presence of bird voices in an audio file for the purpose of studying bird migrations from a given area is an urgent problem. This paper examines ways of building a machine learning model based on the analysis of spectrograms, which will help to accurately identify the presence of bird voices in an audio file for the purpose of studying the migration of birds in a certain area. The research involves the collection and analysis of audio files that can be used to identify characteristics that will identify the sound of the files as birdsong or the absence of sound in the file. The use of the CNN model for the classification of the presence of bird voices in an audio file is demonstrated. Special attention is paid to the effectiveness and accuracy of the CNN model in the classification of sounds in audio files, which allows you to compare and choose the best classifier for a given type of file and model. Analysis of the effectiveness and accuracy of the CNN model in the classification of sounds in audio files showed that the use of Mel-spectrograms is better than the use of STFT-spectrograms for studying the classification of the presence of bird sounds in the environment. The classification accuracy of the model trained on the basis of Mel spectrograms was 72 %, which is 8 % better than the accuracy of the model trained on STFT spectrograms.

Published: February 2024

The main problems of detection and available methods of correcting errors in encoded messages with Fibonacci matrices, which make it possible to find and correct one, two and three errors in the same or different lines of the code word, are analyzed. It has been found that even in the last decade, many scientists have published a significant number of various publications, each of which to one degree or another substantiates the expediency of using Fibonacci matrices for (de)coding data. It has been established that the elements of a codeword obtained by multiplying a message block by a Fibonacci matrix have many useful properties, which are the basis for the method for detecting and correcting errors in them. The statement is given, according to which the ratio of the corresponding elements of the code word is close to the golden ratio, which is important for the existing methods of correcting potential errors. This property of the elements makes it possible to identify the presence of double and triple false elements by checking whether their ratios belong to a fixed interval. It is found that the false affiliation indicates that there are two errors in different lines of the codeword, which require solving the corresponding Diophantine equations, the suitability of the solution of which must satisfy certain conditions for error correction. It was found that in order to correct two errors in one line of the code word, a condition was introduced according to which the set of blocks of the input message should contain only minimal matrices, which makes it possible to take the smallest solutions of the Diophantine equation, the suitability of which is specified by test ratios. It was found that in order to correct three errors in a codeword, it is necessary to check whether the relations of its corresponding elements belong to a fixed interval and to solve a nonlinear Diophantine equation, the implementation of which is extremely difficult. The proposed approach boils down to trial and error, according to which you first need to find the exact location of the erroneous elements, and only then correct them according to the appropriate methods.

Published: February 2024

Employee job satisfaction is one of the things that the South Kuta District Office pays attention to, especially for Non-Civil Servant Employees who work there. This has prompted researchers to examine the job satisfaction of non-civil servants at the South Kuta District Office. The sample in this study was 53 people or all non-civil servant government employees at the South Kuta district office. The sampling technique uses saturated sampling. The researcher uses the saturated sample technique because the population is more than adequate, and all employees in the company are considered to be able to be used as research samples. Data was analyzed using path analysis. The result is considered imperfect due to the small population of the research location. This research was carried out at the South Kuta sub-district office, where the object was limited to one sub-district. The weakness in this study also lies in the results where independent variables can affect dependent variables with 38.7%. The value of the influence in this study is considered to be small. The research found that Role conflict significantly affects job satisfaction and job stress. Job stress also significantly affects job satisfaction and has indirect effects on role conflict toward job satisfaction.

Published: February 2024

Industrial symbiosis (IS) is a practical approach to sustainable economic and environmental management involving exchanging materials, energy, water, and by-products among industries. While IS has been extensively studied in developed countries, its implementation in developing countries still needs to be improved. The purpose of the research was to assess the influence of geographical proximity and symbiotic intensity on the exchange of solid waste materials. This study employed a descriptive, cross-sectional research design and examined 41 manufacturing industries in Kisumu County, Kenya. A combination of quantitative and qualitative data was collected through questionnaires administered to technical officers in the industry. Besides, in-depth interviews with industry experts, county administrators, and industry association representatives were conducted, providing valuable insights and perspectives on the subject matter. The findings established that geographical proximity did not significantly influence types of waste exchanged (p = 0.298, p = 0.327, and p = 0.535) using nutrient-value waste as the reference category. This finding was likely due to high variability in distance between industries in the symbiotic exchanges. In contrast, the symbiotic intensity statistically significantly influenced the amount of solid waste reused in the network (Adjusted R2 = 0.113, p = 0.039). Furthermore, it was established that increasing the number of actors in the network (β = 0.324) can significantly impact solid waste reuse more than increasing the number of types of waste being exchanged (β = 0.243). This study underscores IS as a sustainable alternative to conventional manufacturing, especially in developing countries, while indicating that factors other than geographical proximity shape symbiosis.

În acest cadru am prezentat modul în care Curtea Constituțională a apreciat că ar trebui să se asigure verificarea ex post a supravegherii tehnice, precum și noua reglementare procedurală cu evidențierea titularilor plângerii, a organelor judiciare competente să o soluționeze și a obiectului analizei judecătorului de cameră preliminară.

Deopotrivă, au fost evidențiate multiplele ipoteze de interpretare ale dispozițiilor generale ale procedurii apte în scopul evitării dificultăților viitoare de interpretare și aplicare a normei.
Repere privind statutul legal al ‘platform workers’. Propunerea de Directivă privind îmbunătățirea condițiilor de muncă pentru lucrul pe platforme vs. „testul ABC”
Authors: Albanezi Albert
Published: February 2024

‘Gig-economy’ sau „munca la cerere” (‘on demand work’) reprezintă o concretizare a pieței digitalizate de muncă, creată și dezvoltată cu ajutorul platformelor digitale de muncă ce pot lua forma aplicațiilor mobile. Teoretic, raporturile dintre platforme și lucrători nu sunt raporturi de muncă, respectiv nu prezintă un caracter de continuitate. Practic însă, controlul exercitat asupra serviciului prestat poate fi interpretat în sensul manifestării autorității de către angajator. În încercarea de a alinia realitatea faptică și o calificare corespunzătoare, lucrarea de față prezintă două abordări asemănătoare, respectiv Propunerea de Directivă privind îmbunătățirea condițiilor de muncă pentru lucrul pe platforme și „testul ABC” aplicabil în California. În analiza noastră vom prezenta prezumțiile pe care se bazează aceste soluții, arătând și implicațiile posibile.
Indícios de circulação da cultura escrita em contextos sediciosos de finais do Brasil colonial
Authors: Moreno André Luiz Alves
Published: February 2024

Este texto apresenta indícios sobre o processo de circulação da escrita nos movimentos de insurreição de finais do período colonial, com base nos processos devassatórios da Inconfidência Mineira (1789), da Revolta dos Letrados (1794) e da Conspiração dos Alfaiates (1798). Parte-se dos pressupostos teórico-metodológicos do campo da História da Cultura Escrita, uma forma específica de História Cultural, que compreende quaisquer manifestações humanas como passíveis de serem objetos de estudo da ciência histórica. Para a grande área da Línguística Histórica especificamente, as pesquisas sobre a difusão social e a circulação da escrita são fundamentais, pois forcenem contributo substancial para a contextualização das fontes e dos perfis sociológicos de quem leu e escreveu nos idos do Brasil, dando-nos margens de análise mais aproximadas das facetas diacrônicas do português que aqui foi introduzido, se difundiu e se consolidou.
Descrição e prescrição: sobre os usos gráficos e a ortografia em sincronias passadas
Authors: Lima Maria Hozanete Alves de , Melo Felipe Morais de
Published: February 2024

A descrição dos usos gráficos e a prescrição ortográfica são dois motores que atravessam a pleno funcionamento toda a história da língua portuguesa, a datar do século XVI, com as primeiras obras metaortográficas, até os dias de hoje, com as pesquisas linguísticas ou a escola, por exemplo. São eles os propulsores deste trabalho, cujo objetivo é levantar uma reflexão, através de um repasse historiográfico, a respeito da presença dos tratados e tratadistas nas investigações de Grafemática Histórica voltadas para o português brasileiro (PB) de maneira a problematizar a contribuição dessas fontes para entender a engrenagem da língua escrita e da ortografia em sincronias passadas, sobretudo no Brasil. Para tanto, percorrem-se três etapas, cada qual fundamentada majoritariamente nas premissas e ideias de um autor ligado aos estudos diacrônicos: 1º. partindo de Ramírez Luengo (2012), um inventário de algumas pesquisas nacionais relacionadas ao PB na área da Grafemática Histórica; 2º. a apresentação do intrincado cenário histórico, no mundo lusófono, tanto das ideias ortográficas, com aporte central em Gonçalves (2013), quanto da sociedade brasileira; e 3º. a reflexão, nas trilhas provocadas por Morais de Melo (2018), acerca das pesquisas grafemáticas de orientação diacrônica voltadas ao PB em face do complexo quadro metaortográfico e extralinguístico exposto. O trabalho identifica uma prevalência do uso de tratadistas nas pesquisas em apreço e constata, nas veredas lusófonas, não só uma peculiar e bastante acentuada profusão de ideias ortográficas mas também uma realidade de bastante penúria social e educacional no Brasil. Do cruzamento desses resultados, repensa o papel dos tratadistas nos estudos da língua escrita em perspectiva diacrônica dirigidos ao PB.

Published: February 2024

The study delves into the delegitimization of religion during the COVID-19 pandemic, addressing not only the social aspects of religious life but also the social significance of religion itself. It explores how this delegitimization, particularly in Islam, has altered the sacredness of religious life. This qualitative research, utilizing literature review and media analysis, aims to uncover the forms of religious delegitimization that have transformed the face and substance of religion during the pandemic. It investigates 1) how this process has changed the legitimacy of religion, 2) the patterns of belief and worship, and 3) the context and factors underlying this delegitimization. The findings reveal that religious delegitimization during the pandemic is a part of the process of objectifying religion in a health disruption, highlighting changes due to COVID-19 regulations, understanding of religious sacredness, and the authority of religious figures in the context of religion and COVID-19 controversies.
