Authors: Parreira André Luís , Carvalho Paulo Simeão
Published: August 2021

Este artigo apresenta o processo de tradução para língua portuguesa e validação no Brasil do teste conceitual Kinematics Concept Test (KCT), produzido originalmente por investigadores da ETH Zurich. O teste se propõe avaliar a aprendizagem de conceitos de Cinemática, uma área que representa um dos maiores desafios para os professores que ensinam Física no Ensino Médio. As questões desse teste se estruturam sobre representações de tabelas de valores, imagens/desenhos e gráficos.

Após traduzido e validado o conteúdo, sua validação de confiabilidade aconteceu com 118 estudantes do primeiro ano do Ensino Médio do Colégio de Aplicação da Universidade Federal de Viçosa, que alcançaram resultados equivalentes aos dos estudantes suíços que participaram da validação da sua versão original.

As técnicas empregadas no processo de validação, bem como seus resultados, apontam para um consistente grau de fiabilidade, mostrando assim que o KCT é uma ferramenta muito útil para os professores realizarem uma avaliação formativa com os seus alunos, bem como para projetos de pesquisas que requeiram avaliação do nível de conhecimento em Cinemática de estudantes de língua portuguesa.
Investigating DNA Damage Mechanism Induced by Monosodium Glutamate and Associated DNA Repair Cell Machinery: A Literature Review
Authors: Aghaei Novin , Grigorescu Teodora , Katani Nia
Published: August 2021

Introduction: Monosodium Glutamate (MSG) is a widely used food additive to enhance flavours. Though commonly used, MSG’s accumulation in the body can induce genomic instabilities. These genome instabilities are detectable through various methods such as Random Amplified Polymorphic DNA Polymerase Chain Reaction (RAPD-PCR) and comet assay. Additionally, cells can employ DNA repair mechanisms to ameliorate this damage. The objective of this review paper is to investigate the role of prolonged MSG ingestion in DNA damage, potential downstream diseases, and DNA repair mechanisms that cells undertake to counteract these effects, such as nucleotide excision repair (NER) and base excision repair (BER). Compounds such as vitamin C, green tea extract, and Allium sativum have been shown to ameliorate the health hazards of MSG by inhibiting oxidative stress, reducing apoptosis, and increasing antioxidant availability.
Methods: This review focuses on MSG-induced DNA damage mechanisms including gene suppression, chromosomal disruption, and carcinogenic effects. We conducted a comprehensive literature review of 28 peer-reviewed articles published since 2000-present.
Results: Studies show that MSG consumption may lead to the formation of Reactive Oxygen Species (ROS) and micronuclei (MN), which are known as biomarkers of carcinogenesis. Furthermore, the genomic instabilities that lead to this effect were identified through the use of RAPD-PCR and comet assays. These instabilities are mainly dealt with by endogenous repair machineries such as NER and BER. Also, researchers have identified many substances which act as preventative measures towards the potential harmful impacts of MSG.
Discussion: Diseases, such as cancer and obesity, may be linked to chronic intake of MSG. The efficacy of the mentioned DNA damage detection methods will be discussed. Furthermore, the endogenous mechanisms of NER and BER are outlined in this review. Substances such as vitamin C, green tea extract, and Allium sativum aid to prevent genotoxic effects induced by MSG.
Conclusion: Through this research, we hope to bring awareness to the harmful impacts of MSG on genome stability and its role in disease development. We aim to educate the public about the prevalent usage of MSG in the food industry and to inform individuals to take precautions in their food consumption.

Vulneración de derechos humanos por el extravío de cuerpos durante la pandemia por la covid-19 en Ecuador
Authors: Carrión Intriago Freddy Vinicio
Published: August 2021

La pandemia de la covid-19 resquebrajó a la sociedad ecuatoriana y evidenció una crisis económica estructural sin precedentes que afectó gravemente a los sectores más desprotegidos e hirió profundamente la memoria colectiva. El presente artículo analiza los derechos humanos vulnerados en Ecuador durante el 2020, principalmente en Guayaquil debido al mal manejo de los cadáveres y su posterior extravío. La investigación se centra en establecer qué derechos humanos vulneró el Estado por acción u omisión en el marco de la crisis sanitaria. La metodología elegida fue la revisión de literatura analítica que permite establecer un marco teórico para analizar los impactos del virus más allá del ámbito de la salud. También se usó información levantada por la Defensoría del Pueblo y los datos de la prensa nacional e internacional, así como de las organizaciones de la sociedad civil. De esta forma, el artículo pretende ser una denuncia pública derivada del trato inhumano e indigno que se dio a los cuerpos de las personas fallecidas en el marco de la pandemia. Por otro lado, abre el debate social y académico sobre la dignidad humana y el manejo de cadáveres, de tal forma que el ejercicio se convierta en una garantía de no repetición. Y, que la memoria de los cuerpos que aún no son entregados a sus familias sea una constante que nos interpele como sociedad para demandar que el Estado cumpla con su rol de garante de los derechos humanos de todos y todas.
¿Es eficiente el uso de la tecnología SIG, en la Gestión de la Política Pública?
Authors: Castro Yunapanta Wilfrido Manuel
Published: August 2021

La recuperación de edificaciones patrimoniales es conceptualizada desde una visión de sostenibilidad al reutilizar estructuras que ocupan un espacio privilegiado de la ciudad,que contienen unos saberes heredados del pasado y fomentan un sentido de pertenencia en la ciudadanía. Uno de los problemas que enfrentan estas estructuras es la falta de mantenimiento debido a los costos que implica su intervención, por lo que el Municipio de Quito promueve una política de incentivos para mejorar las condiciones de habitabilidaden este tipo de bienes.
Esta investigación tuvo como objetivo evaluar la eficiencia de esta política pública en territorio, utilizando las herramientas SIG de código abierto y la infraestructura de datos espaciales de la ciudad. Los resultados indicaron que los incentivos se concentran enel área central de la ciudad, por lo tanto, las parroquias urbanas y rurales quedan como espacios desatendidos. Se concluye que el uso de la tecnología de los sistemas de información geográfica presenta la ventaja de ver la facilidad y flexibilidad en la especialización de datos, y permite correlacionar variables como la densidad poblacional con los estados de conservación de las edificaciones. La información obtenida ayuda a lostomadores de decisión a evaluar la eficiencia en la aplicación de la política pública, y a prevenir posibles fallas en su aplicación.

Authors: Falconí Suárez Franklin Eduardo , Loachamin Daisy , De la Cruz Cintia
Published: August 2021

En este artículo se analiza la discriminación en los mensajes de la televisión local contra los ciudadanos venezolanos que habitan en el cantón Latacunga y cómo les afecta en su vida cotidiana. Se utilizó un diseño no experimental, descriptivo y correlacional, desde un enfoque cualitativo. Además, se aplicó técnicas como la observación estructurada, que partió del monitoreo diario del programa Reporteros en Acción de TV Color Canal 36, durante el primer semestre de 2019. Asimismo, se llevó a cabo un grupo focal con nueve ciudadanos venezolanos que no cuentan con un trabajo formal. Los resultados obtenidos evidencian que la información difundida es discriminatoria, producto de las prácticas de cobertura periodística estandarizadoras, reduccionistas y que naturalizan una imagen negativa de estas personas, lo cual genera rechazo en la población local y facilita las condiciones para abusos de diverso tipo. El estudio concluye que la población migrante expresa la necesidad de reconocimiento e integración intercultural en condiciones de equidad, sobre la base de una visibilización adecuada de sus rasgos culturales y éticos, lo cual no es posible si los medios no cambian sus prácticas de cobertura informativa.

In general, the notion of a cooperative is a business entity that is owned and managed by its members. Meanwhile, multi-business cooperatives are cooperatives whose business activities are in various economic aspects such as savings and loans, production, consumption and services, which consist of people or cooperative legal entities by basing their business activities on the cooperative principle as well as a people's economic movement based on the principle of kinship. This research took place in one of the cooperatives in the village of Rensing, East Lombok, with the cooperative name "Daruzzakah". This cooperative is a multi-business cooperative with one type of activity is to provide savings and loans or credit to its members. The purpose of this cooperative is as an alternative means of borrowing money or credit as well as trying to prevent its members from loan sharks. However, in practice there are problems, namely the number of delays and credit payments that are not on time. Judging from the large number of customers who borrow funds, a strategy is needed to be able to fulfill all of these activities, the increasing number of prospective customers applying for credit with different economic conditions, requiring accuracy in making credit decisions. To avoid this, it should be necessary to analyze member data to determine the feasibility of providing credit, so that it can be classified as whether or not to get a loan. Data analysis can be done using data mining techniques. For this reason, the authors try to provide solutions to these problems by applying the naïve Bayes algorithm in predicting and determining creditworthiness. The Naive Bayes algorithm has been widely used by previous researchers and has high accuracy values. In this study, the Naive Bayes algorithm was used and resulted in an accuracy value of 96.45% with an AUC value of 0.942 which means it is a good classification.
An Association of Vitamins A and E with Hyaluronic and Lactobionic Acids may Prevent Molecular Changes Associated with Keratocyte to Myofibroblast Transition

Published: August 2021

Inflammatory events in the corneal stroma may activate keratocytes and trigger their transition towards myofibroblasts, which now produce different extracellular matrix (ECM) proteins thus causing corneal opacification.Corneal haze is a frequent side effect after photorefractive keratectomy (PRK) to correct high myopia.Currently, a preventive treatment with mitomycin-c can be used to limit the occurrence of this phenomenon. However, mitomycin-c is a toxic drug, not devoid of side effects, which may occasionally involve the corneal endothelium. Therefore, we have searched for a less risky, natural way, to prevent keratocytes transition. To this purpose, we have used as markers of the phenotype switch the proteins lumican (highly expressed by keratocytes and much less by myofibroblasts) and smooth muscle actin (αSMA) (highly expressed by myofibroblasts and poorly found in keratocytes), beside Fibronectin (Fn), the expression of which is also increased by transforming growth factor-beta (TGFβ treatment. Treatment of human keratocytes with TGFβ was used to induce the protein shift. Among different possible candidates, we have found that vitamins A and E, hyaluronic and lactobionic acids may prevent, either alone, or much better in association, the shift in the ratio between lumican and αSMA and the increased Fn expression. In conclusion, it could be speculated that topic treatment of the ocular surface with an association of these four compounds could be able to prevent or at least limit the occurrence of post-PRK corneal haze, with the additional advantage of lubrication, hydration and antioxidant defense exerted by these molecules.

The analysis was carried out with methanol extract and one hundred and seventy-six (176) phyto-constituents identified and scored at different retention times ranges from 3.22min in I. hexaloba (Pierre) Engl. & Diels. to 34.56min in I. campanulata Engl. & Diels.. The prominent compounds were scored in carboxylic and its derivates while the least compound was identified in alkyne. Highest M.wt. was 741.5 in I. congolana (De Wild.&T.Durand) Engl. & Diels. at retention time of 34.52 min and the lowest M.wt. was 84.15 in I. thonneri (De Wild.&T.Durand) Engl. & Diels. at retention time 3.44 min. Hexadecanoic acid, methyl ester formula C17H34O2 and M.wt of 270.4 was scored in all the six species suggested a diagnostic characters for the genus Isolona. Quantitatively, the amount of the analytes isolated in all the species ranges from 0.1% in I. hexaloba to 59.36% in I. thonneri. Two UPGMA distant trees were constructed with RMSD and Euclidean index to illustrate the relationships among the Isolona species based on the difference chemical constituents. The distance tree revealed the separation of I. thonneri from all other species, also a sub-cluster tree of I. hexaloba, I. campanulata and I. zenkeri (Engl.) Dyer. was also constructed. The highest distance value level is 9.576 scored between I. thonneri and I. congolana while the highest similarity level was 2.911 scored in I. hexaloba and I. campanulata. The overlapping phyto-constituents characters revealed the closeness of the taxa studied, this invariably will update the existing data in the genus and ultimately in the family Annonaceae.

Published: August 2021

Rapid prototyping is closely related to 3D printers (additive manufacturing). Rapid prototyping is a technique for making a prototype model from a CAD file which is the final result, while a 3D printer is one of the processes. The 3D printer process is by melting the filament layer by layer to form a component or product. The 3D printer melting process uses a heater on the nozzle. This study aims to analyze the effect of nozzle diameter and layer thickness on the accuracy (dimensional measurement) of 3D printer objects. To determine the precision, a test object was made based on ASTM D995-08. The variation of nozzle diameter used is 0.2 mm and 0.5 mm, while the variation in layer thickness is 0.1 mm and 0.3 mm. In this study, delta type 3D printing was used with polylactic acid (PLA) material to make test objects. Dimension measurement using ASTM D5947-06. Analysis of the measurement results used ANOVA with a 2-level factorial design type and a 2 factorial interaction (2FI) model design using Design-Expert®. software. From the actual measurement results, the most accurate (precise) results are obtained on the test object with a variation of the nozzle parameters with a diameter of 0.2 mm and a layer thickness of 0.1 mm. From the analysis of the specimen measurement data, it can be concluded that the nozzle diameter significantly affects the response of length, width and height while the thickness of the layer affects the response of the length and width of the specimen.

Observational and randomized data show equivalent results as compared to overnight observation. In addition, it ensues great savings for the healthcare system. Nevertheless, in Brazil, this approach is underused. The objective of this study was to describe the characteristics and outcomes of patients undergoing percutaneous coronary intervention with same-day discharge. Methods A single-center study with patients who underwent selected procedures, uneventful, discharged on the same day. Clinical and angiographic characteristics were described. Major cardiovascular events and complications were analyzed, reported, and compared to a historical cohort. Results A total of 413 patients were included, mean age of 64±10 years. After a 30-day follow-up, no major cardiovascular event was observed in selected patients submitted to the same-day discharge strategy. In addition, we found an increase in clinical and angiographic complexity as compared to the previous series, which did not translate to rise in adverse outcomes. Conclusion Uncomplicated percutaneous coronary interventions, with same-day discharge, are safe among appropriately selected patients, encouraging further adoption of this approach.

The volume of complex coronary interventions has grown in Brazil and worldwide. Since they are performed in patients at increasingly higher risks, new techniques have been developed when interventional cardiologists are faced with uncommon situations, such as no safe arterial access for the procedure. We report a case of a patient with severe peripheral artery disease and occluded right femoral artery, in whom a single access (left femoral artery) was used for positioning the Impella™ and the guidewire for angioplasty.

Jenis tumbuhan di bawah tanaman kelapa sawit antara lain rumput-rumputan, tumbuhan berdaun sempit, tumbuhan berdaun lebar yang dikelompokkan dalam gulma. Namun, ada juga tumbuhan leguminosa. Jenis leguminosa ini juga dibudidayakan di bawah tanaman kelapa sawit saat tanaman masih muda dan berfungsi sebagai penutup tanah, maka penutup tanah di perkebunan berfungsi untuk menjaga kelembaban tanah dan menjaga kesuburan tanah. Istilah lain gulma adalah tumbuhan pengganggu, yang mengandung pengertian semua jenis tumbuhan yang menghambat dari berbagai jenis tanaman yang diusahakan atau dibudidayakan baik oleh petani maupun usaha pertanian swasta. Gulma tersebut perlu diberantas, namun gulma dapat menjadi tanaman yang sangat dibutuhkan oleh ternak sebagai sumber hijauan.
Vaccinating adolescents in England: a risk-benefit analysis

Published: August 2021

The UK JCVI committee recently announced that vaccines would not be offered to all 12-17 year olds, as the potential risks were not outweighed by the benefits. Here, we offer a quantitative risk-benefit analysis of vaccines among 12-17 year olds in England, showing that the benefits of vaccination greatly outweigh risks among12-17 year olds in England in the current context.

Sistem pertanian terpadu telah menjadi bagian dari budaya bertani di Indonesia. Sistem ini mampu memanfaatkan sumber daya lokal yaitu bahan ikutan berupa jerami, serta kotoran ternak secara efisien. Ciri utama sistem pertanian terpadu adalah adanya keterkaitan antara tanaman dan ternak misalnya limbah tanaman jagung (jerami) digunakan sebagai pakan ternak, begitupun sebaliknya kotoran ternak dapat digunakan sebagai pupuk organik untuk tanaman. Sistem pertanian terpadu memberikan keuntungan kepada petani yaitu pupuk kandang sapi dan bahan ikutan pertanian berupa jerami. Pupuk kandang sapi selama ini belum optimal digunakan dapat dimanfaatkan sebagai pupuk organik untuk meningkatkan kesuburan tanah atau dapat dijual sebagai sumber pendapatan. Limbahpertanian yang tersedia dapat dimanfaatkan sebagai sumber pakan yang berkualitas, sehingga mengurangi biaya penyediaan pakan.

The Psychological Costs of Painless but Recurring Experiences of Racial Discrimination
Authors: Huynh Que-Lam , Devos Thierry
Published: August 2021

When studying discrimination, it is important to examine both perceived frequency and stress associated with these experiences, as well as the interplay between these two dimensions. Using data from Latino/a participants (N = 168), we found an interaction effect of the reported frequency and reported stressfulness of discrimination on psychological distress (depression and anxiety), such that frequency predicted greater psychological distress for low-stress events, but high-stress events were associated with greater distress regardless of frequency. In addition, using the constructs of “stated” and “derived” stressfulness, we found that the frequency of experiences of discrimination that were rated as less stressful were in fact correlated with greater psychological distress. Discrimination events not experienced as stressful nonetheless may have negative implications for the target, especially if they occur frequently.

Background: Tuberous Sclerosis Complex (TSC) is a single gene disorder carrying high risk of autism spectrum disorder (ASD). Various neurological complications increase the risk of ASD but the way risk factors operate together is unclear. We aimed to explore risk pathways to ASD by modelling the interplay between genetic mutation (TSC1/TSC2), cortical tuber count, seizure type and severity. Methods: The Tuberous Sclerosis 2000 Study is a UK longitudinal study of the natural history of TSC. We recruited newly diagnosed children (N=125) and collected data on mutation, cortical tuber count (cranial MRI/CT), seizure history, and IQ. ASD and IQ assessments were carried out at 10-year follow up (N=86, M age=13.1 years). Structural equation modelling (SEM) was used to explore pathways that mediate between mutation and ASD symptoms. Results: Risk of ASD was high: 39.5% met research criteria for ASD and a further 41.9% showed autistic traits. SEM resulted in two indirect pathways, with cortical tuber count and occurrence/severity of epileptic spasms in infancy mediating between mutation and ASD (mutation-tubers-spasms-ASD, B=2.08, 95%CI 0.15–8.02; mutation-spasms-ASD, B=2.98, 95%CI 0.04–8.89). Concurrent seizures (B=3.08, 95%CI 0.42–6.18) and IQ (B=-117.10, 95%CI -183.57–-59.16) were also associated with ASD symptoms. Conclusions: There was significantly elevated risk of ASD and subclinical autistic traits. Tuber count and severity of spasms predicted ASD severity, suggesting that prevention/control of seizures in infancy may decrease severity of ASD symptoms. ASD was occasionally reported in the absence of overt seizures in infancy, so their causal role requires further investigation.
Boundaries of American Identity: Relations between Ethnic Group Prototypicality and Policy Attitudes

We sought to document that the extent to which different ethnic groups are perceived as embodying the American identity is more strongly linked to anti-minority policy attitudes and acculturation ideologies among majority group members (European Americans) than among minority group members (Asian Americans or Latino/as). Participants rated 13 attributes of the American identity as they pertain to different ethnic groups, and reported their endorsement of policy attitudes and acculturation ideologies. We found a relative consensus across ethnic groups regarding defining components of the American identity. However, European Americans were perceived as more prototypical of this American identity than ethnic minorities, especially by European American raters. Moreover, for European Americans but not for ethnic minorities, relative ingroup prototypicality was related to anti-minority policy attitudes and acculturation ideologies. These findings suggest that for European Americans, perceptions of ethnic group prototypicality fulfill an instrumental function linked to preserving their group interests and limiting the rights afforded to ethnic minorities.
Modeling Concept System
Authors: Li Fangfang
Published: August 2021

Understanding thinking and realizing human-level artificial intelligence have long been regarded as one of the ultimate dreams. However, most of the studies dedicated to this goal are in a direction that could never achieve it. This direction is that trying to explain intelligent behavior by human-summarized codes of conduct. Expert systems, machine learning, and almost all theories that interpret psychological phenomena are products of this idea. Since the code itself is one-sided, this method is limited from its beginning. To truly understand the thinking, we must embrace a new way: treat all codes of conduct, such as rationality or survivability, as phenomena rather than a goal of intelligence. These phenomena will emerge based on some basic settings when the intelligent machine interchange information with the outer world. In this paper, we will model the data structure of thinking, namely, the concept system, which is the first part of modeling thinking based on the idea above. To demonstrate the power of this model, we discussed how cognitive phenomena can emerge based on this model. These phenomena include recognition, reasoning, causality, semantic concepts, and the concept of concepts.
