STROBOSCOPIC VISION TRAINING
Authors: Fuerst Randy , Lynch Hannah , Kohmescher Kevin
Published: August 2024

The use of liquid crystal stroboscopic sports vision training dates back to our introduction in 1995. With vision being the predominant sensory modality driving a motor response—whether hitting a baseball, shooting a basketball, a goalie stopping an incoming puck hurtling towards him—coaches, sports psychologists, researchers, and sports vision doctors have worked to develop strategies to improve performance. What can be measured for the entire neuro-visual processing? Can you improve this processing? If so, what are the most effective regimens? How long does it last? What is it that the athlete visually discriminates on for meaning and expertise? Saccadic eye movements are the most common visual skill for acquiring a target. When making these eye movements, the brain ‘masks’ the visual world for a few milliseconds until the eye come to a stop. This is known as saccadic omission and suppression. Are there effective strategies to minimize the effect and speed up the saccadic eye movements? Can we improve fixation accuracy? Decrease latencies? Improve target acquisition, sometimes referred to as dynamic visual acuity? A body of research quickly uncovers what stroboscopic vision training (SVT) can and cannot impact. Both anecdotal and statistically significant research studies shed light on SVT enhancing central visual processing, visual concentration, and athletic performance tied to the subskills impacted by SVT.

Published: August 2024

Aluminum which is considered as a metal with use and great perspective belongs to the group of non-ferrous metals due to its low density and suitable physical, mechanical and chemical properties which make its application possible in many branches of modern industry.
The mechanical and physical properties of aluminum are significantly improved by its connection with other elements such as; like, Mg, Mn, Cu etc., can be used for the production of various industrial products by molding, lamination, pressing, stamping etc. In this paper the AlSi10Mg alloy was treated, the samples were analyzed by thermal analysis, heat treatment through hardness, the results which showed that the alloy hardness was significantly increased compared to before heat treatment. The purpose of this paper is to look closely at the stages of hardening and the change in hardness after melting and after heat treatment.
After the thermal analysis, the stages in detail of their creation in the laboratory conditions used during the experimental work with melting and the solidification process are defined.
Experimental work showed that microstructural and mechanical properties changed with heat treatments. It was observed that heat treatment has a great effect to increase hardness of AlSi10Mg. According to Optic Microscope (OM) analysis it can see formation of different phases.
Arte, rua e culturas juvenis: circuitos da etnobiografia – Eu mermo Eduardo Africano
Authors: Diógenes Glória Maria dos Santos
Published: August 2024

Este artigo versa sobre culturas juvenis traçadas em percursos de ruptura família-casa-rua. Ele tem por objetivo compreender de que modo tais percursos possibilitam experiências de reelaboração das linguagens de si e do mundo, e a projeção de singulares trajetórias artísticas. Trata-se de um estudo metodológico de natureza etnobiográfica. Por meio da singularidade da trajetória de um emblemático jovem denominado Eduardo Africano, pôde-se abrir espaço para a compreensão da realidade sociocultural de tantos outros considerados parte da geração Nem, Nem, Nem (NNN). O artigo destaca o considerável número de juventudes que se situa em denominadas e estigmatizadas zonas de perigo, geográficas e morais. Africano, negro, morador de periferia, tendo passagem pelas medidas socioeducativas em meio fechado, pelo extensivo tempo de moradia na rua, poderia potencialmente ter se perpetuado no quadro das estatísticas do NNN. Seguindo um percurso singular, ele contraria as estatísticas, torna-se: eu mermo. Em suas linhas finais e conclusivas, o artigo aponta para a vida como matéria da arte, bem traduzindo aquilo que Rancière (2005) denominará de “partilha do sensível”.
Juventudes e documentário em Visionários da Quebrada: cidade, espaço-tempo, fronteiras
Authors: Almendary Livia Chede , Borelli Silvia Helena Simões
Published: August 2024

Este artigo examina em que medida o documentário Visionários da Quebrada (2018, 90’, dir. Ana Carolina Martins), com suas formas específicas de produção e circulação, constrói discursos contra-hegemônicos em relação à invisibilização, estigmas e estereótipos que recaem sobre territórios periféricos de São Paulo e seus habitantes. O filme é realizado por um coletivo de jovens que fomenta o pensamento crítico sobre a constituição da cidade, cuja relação espaço-temporal é, desde o período colonial, marcada pela segregação e pelo racismo. O estudo de caso, de base qualitativa e interdisciplinar, analisa como Visionários da Quebrada — tanto pela narrativa fílmica quanto por sua estratégia de distribuição — convoca o público a se afetar pela cidade, conhecê-la criticamente e questionar divisões, segregações e processos de invisibilização construídos historicamente pela branquitude e suas expressões na organização do território. Fundamentado nos Estudos Culturais e Pós-Coloniais (assim como em suas reverberações latino-americanas), além de outras referências dos campos da História, da Comunicação e da Antropologia, o artigo se aproxima de uma perspectiva de antropologia visual que aborda o audiovisual, em particular o cinema, como ferramenta de grande importância na construção de identidades e cidadanias.
Apresentação: Juventudes, estéticas e políticas: agenda de pesquisa perante os desafios do século XXI
Authors: Marcon Frank , Raposo Otávio
Published: August 2024

As culturas juvenis e as suas intervenções estéticas são fenômenos de extrema relevância para a compreensão dos jovens como sujeitos políticos. Incentivados pelos dispositivos digitais, eles promovem trocas econômicas e simbólicas que desafiam o controle estatal e o estatuto de subalternidade que lhes é imposto, principalmente quando se trata de uma juventude desfavorecida e racializada. Perante um século de incertezas, as intervenções estéticas e políticas dos jovens são bastante profícuas para problematizar as profundas mudanças que estamos a viver em relação às sociabilidades, identidades, afetos, consumo, desigualdades sociais, crise climática e pandêmica, resistências e mobilizações artístico-ativistas. Este artigo trata desse conjunto de temas a partir da perspectiva das ciências sociais, em particular da antropologia, e em diálogo com as pesquisas etnográficas dos autores do presente dossiê. Trata-se de um artigo de apresentação que visa apontar tendências e hipóteses sobre as transformações nos modos da fazer juvenis, num período em que a hiperestetização da vida cotidiana e a expansão das tecnologias digitais recolocam a linguagem do político em outros domínios do simbólico, com efeitos no modo como os jovens produzem imaginários, visibilidade e agência. Se a arte e a estética têm gerado novas formas de fazer política, não menos importante são os processos de dominação e controle sobre os meios que viabilizam a produção e a circulação da criatividade juvenil. Destacamos, ainda, as contribuições dos seis artigos aqui reunidos, cujas ricas análises etnográficas problematizam a tríade juventudes, estéticas e políticas sob a ótica das subjetividades e experiências vividas.

Authors: Wang Fang , Du Wen
Published: August 2024

Based on the current situation of advanced mathematics curriculum teaching, this study first constructs a blended learning model for advanced mathematics based on SPOC through literature research from three aspects: curriculum design, teaching implementation, and learning evaluation. And designs a specific blended teaching case combined with the "definite integral concept". Then, we conducted a purposeful sampling in a public school called Qinghai Normal University and selected 82 students from two first-year classes majoring in biotechnology as the research objects, and carried out an 18-week empirical study with experimental control. Finally, the final grades and teaching evaluation questionnaires of students in advanced mathematics were collected for data processing and analysis. The research results showed that students in the SPOC blended learning class had better math scores than those in the traditional teaching class, and blended learning could narrow the gap in students' math proficiency. At the same time, the questionnaire survey found that students believe that blended learning in advanced mathematics courses has abundant resources, frequent interaction and communication, and can improve learning efficiency. However, traditional advanced mathematics learning puts a lot of pressure, and they are busy taking notes in the classroom and cannot respond to the teacher's questions in time.

Authors: Abboud Fredy , Kenefick Aubrey , Clark Peter , Colman Alexandra , Beltran Celine , Lyons Cameron , Khoury Nouhad , Kristo Kristina
Published: August 2024

The Black, Indigenous and People of Color (BIPOC) Health Promoter (HP) is a preventive medicine-based clinic serving the Black and Indigenous communities in Philadelphia, Pennsylvania. As part of Saint Joseph’s University’s Institute of Clinical Bioethics’ (ICB) health promoter program, the BIPOC clinic is modeled after the ICB’s four other health promoters—African, Hispanic, Asian, and Mobile/Rural. The BIPOC clinic is founded on the principles of education, community outreach, solidarity, respect for the human person, and accompaniment; it is also built on the availability and cohesion among seven elements: 1) program coordinators, 2) volunteering medical and dental professionals, 3) undergraduate and graduate volunteers, 4) organizational partnerships, 5) location, 6) funding, and 7) community support/engagement. Offering monthly medical and dental services to African American and Hispanic communities affected by the opioid epidemic in Philadelphia’s Kensington—an open-air drug market—the BIPOC HP may be a paradigm for preventive medical services and community outreach worth adopting and implementing by city officials in regions struck with illicit substance use.
Identifying and Eliminating the Toxic Work Environment in the Clinical Setting: A Narrative Review
Authors: Eisner Daniel
Published: August 2024

OBJECTIVE: This narrative review seeks to identify the scope, causes, and suggested solutions to both eliminating the toxic work environment (TWE) within a healthcare setting and maintaining a harmonious work environment, especially those in high volume areas such as emergency departments, primary care clinics, and urgent care clinics. BACKGROUND: Despite the end of the COVID-19 Public Health Emergency (PHE), turnover and shortages in the healthcare sector labor force continues at an alarming rate. While the causes have been implicated, little is known about specific practices proven helpful in reversing this trend. METHODS: The selected search engines identified studies published within the last 10 years focusing on the toxic healthcare work environment, workplace stress, burnout, and healthcare worker (HCW) turnover. Suggested solutions were then explored. DISCUSSION: Numerous publications defined attributes of a TWE, as well as causes and damages incurred, but few gave substantial suggestions for management. No studies or articles discussed the development or use of a standardized protocol on how to manage a TWE. CONCLUSION: The TWE is a growing concern for stakeholders, as it affects both the organization and the community it serves. Determining the scope, measuring the damage, and addressing the causes are critical in ending it. Numerous solutions are outlined but a commitment to maintaining a harmonious workplace by all stakeholders is key. More studies are needed to develop best practices for the elimination of the TWE by way of tested and standardized protocols.

Objetivo. Analizar los diseños epidemiológicos más utilizados en el estudio de la relación entre estrés psicológico en los adolescentes universitarios Metodología. Búsqueda bibliográfica con criterios de inclusión y exclusión específicos, Creative Commons, Portal de revistas, Redalyc y revistas electrónicas de diversas disciplinas siguiendo las recomendaciones del estándar PRISMA. Se extrajeron 8170 artículos de los cuales fueron seleccionados 16 para la revisión. Resultados. Más del 90% de los estudios confirmaron la relación entre estrés psicológico en los adolescentes universitarios, determinando que los niveles de estrés mantenidos aumentan el riesgo de aparición de sintomatología en los adolescentes. Del total de estudios, más del 70% fueron de diseño transversal y 25% fuero de tipo descriptivo y el 5% no experimental. La población más vulnerable fue la femenina, especialmente en las profesoras y estudiantes con porcentaje de 33%, mientras el 15% era equitativo. Discusión. En la mayoría de los estudios establecen una asociación unidireccional entre el estrés psicológico en los adolescentes universitarios, en el carácter experimenta se observo diferentes niveles de estrés, en donde se detectó depresión y ansiedad, al analizar las estrategias de afrontamiento y estrés académico, los resultados destacaron el dominio de las estrategias emocionales orientadas a la emoción en el grupo de estudiantes. Conclusión: Los estudios sobre estrés psicológico en los adolescentes universitarios tienen diseños y resultados heterogéneos. Los hallazgos resaltaron múltiples estresores psicosociales y partes del cuerpo afectado, siendo escasos los consensos en diagnósticos e instrumentos de medida. Aunque aparece una asociación entre estrés psicológico en los adolescentes universitarios, no se vislumbran relaciones causales claras. Dado el elevado coste de estos problemas, se considera necesario realizar más estudios con diseños y metodologías rigurosas.
Correlation of Preinjection Values of Gonadotropins and Estradiol Level with Clinical and Radiologic Evidence of Sufficient Pubertal Suppression in Girls with Central Precocious Puberty
Authors: SA Kobra
Published: August 2024

Background: In monitoring of precocious puberty treatment, less attention has been paid to the clinical signs and radiological evidence of puberty control. We evaluated the correlation of preinjection values of gonadotropins and estradiol level with clinical criteria of sufficient pubertal suppression in girls with central precocious puberty. Materials and Methods: 34 patients with CPP were included. After 4-19 dose of depot Triptorelin, blood levels of Estradiol, LH and FSH was measured before next dose of drug. The growth velocity and the bone age advancement were calculated. Correlation of Estradiol and gonadotropins level with clinical and radiologic evidences of pubertal suppression determined. Results: The mean age was 8.82±1.31 years. The mean LH ± SD was 1.02 ±0.53 IU/l (range 0.1-3.55 IU/l). LH/FSH ratio was 0.85±1.3 and 7 girls (20.5%) has LH/FSH ratio above 1. Serum LH level had significant correlation only with FSH (R = 0.589, P< 0.0001). The physical symptoms of puberty (breast tanner stage) were regressed well in 22 (52.9%) but in 12 (47.1%) cases were partially inhibited. Insufficient inhibition of physical signs of puberty was associated with higher growth rate of height (R: 0.422, P = 0.013) and higher BMI-SDS (R: -0.423, P: 0.008). Conclusion: A preinjection value of gonadotropins and estradiol level has not correlation with other criteria of sufficient pubertal suppression in girls with central precocious puberty and is not useful for monitoring of treatment.

Optimizing Machine Learning Performance with The Naive Bayes Classifier Process in Smart Farming
Authors: Saputra Made Yosfin , I Wayan Santiyasa
Published: August 2024

Indonesia is a country that relies heavily on the agricultural and plantation sectors to meet its needs for food and industrial raw materials. But farmers face challenges such as falling commodity prices and the negative impact of global warming, which has resulted in widespread drought. As a result, competition for water resources between the agricultural, industrial and household sectors is getting tighter, making it increasingly difficult for farmers to guarantee water supplies. The phenomenon of global warming has caused challenges in the current era. In Bali, although there is a method called “Subak” to manage rice field irrigation systems, it has not been fully implemented. To overcome this problem, a solution is needed that can automate water distribution based on soil moisture levels, temperature, light and air humidity. It uses machine learning techniques specifically using Naive Bayes Classifier to make real-time decisions regarding crop irrigation. The aim of this research is to increase the efficiency and effectiveness of crop irrigation in agriculture while reducing the impact of warming. The results of testing the scenario with orchid plants obtained an accuracy of around 80% and with general plants obtained around 80% which was tested every time 5 data were collected. Testing with a total of 84 training data and 26 test data. From the test results, an accuracy of 92.30769% was obtained.

Published: August 2024

Abstract
The increasing use of the internet in Indonesia has an influence on the presence of Online Travel Agents (OTA). Through the OTA application, users can book transportation and accommodation tickets more easily and quickly. The increasingly rigorous competition is causing companies like PT XYZ to be able to provide solutions to the needs and problems of their customers in the field of online ticket booking. Many customers submit reviews of the use of the PT XYZ application through Playstore and Appstore, and it needs a technique to group thousands of reviews and detect the topics discussed by customers automatically. In this study, we classified reviews from Android and iOS applications using BERT that had been adjusted through fine-tuning with IndoBERT, as well as modeling topics using LDA to evaluate the coherence score of each sentiment. The result of the comparison of hyperparameter models for the most optimal classification is epoch 4 with a learning rate of 5e-5. The accuracy obtained is 0.91, with an f1-score of 0.74. In addition, testing was carried out to compare BERT with other traditional machine learning. The best performing algorithm was Logistic Regression using TF-IDF word embeddings, achieving an accuracy of 0.890 and an F1-score of 0.865. Therefore, it can be inferred that the accuracy achieved by the fine-tuned classification model of IndoBert is sufficiently high for application in the PT XYZ review classification. Using a coherence score, we found 29 positive topics, 6 neutral topics, and 3 negative topics that were considered the most optimal. This finding can be used as evaluation material for PT XYZ to provide the best service to customers.

Published: August 2024

Algumas pesquisas no campo do Design abordam as propriedades sensoriais dos compósitos termofixos, além de analisá-los qualitativamente sob o prisma da sustentabilidade. Porém, também é necessário que os profissionais possuam informações sobre as propriedades que interferem no produto, tais como densidade, resistência mecânica e custo do compósito, que devem ser considerados em conjunto com dados quantitativos sobre sua sustentabilidade. Já existem algumas ferramentas de simulação e previsão de propriedades para compósitos termofixos, entretanto, caracterizam-se por serem sofisticadas, demandando uma sólida formação na área, além de não serem gratuitas. Uma ferramenta de livre acesso, que estima de forma simples e conforme as necessidades do usuário algumas características do compósito, pode contribuir para difundir e orientar o uso desses materiais. Assim, esta pesquisa objetivou desenvolver uma ferramenta computacional de auxílio a arquitetos, designers e pequenos fabricantes de compósitos que desejem empregar esses materiais em seus projetos e necessitem fazer escolhas a partir de algumas de suas características. Como método, foram pesquisados os softwares e ferramentas computacionais existentes que realizam tarefa semelhante. Em paralelo, baseando-se no público-alvo da ferramenta, foram definidas as propriedades dos compósitos a serem inseridas no processo de escolha, sendo definidos seus métodos de cálculo. Após a estruturação inicial da ferramenta, foram realizadas as simulações de teste, que levaram a aprimoramentos até a versão final. Como resultado, apresenta-se uma ferramenta elaborada a partir do software Microsoft Excel 2019, que possibilita estimar, a partir da matriz e da fibra de reforço selecionada pelo usuário, a densidade, o custo/kg, o percentual de matéria-prima de origem renovável e biodegradável do compósito, a espessura de um laminado feito com ele e o quantitativo de materiais de uma peça feita com esse laminado. O teste final ocorreu a partir de sua aplicação no projeto arquitetônico de um abrigo de ponto de ônibus. A ferramenta funcionou corretamente durante a simulação, sendo possível visualizar os compósitos mais densos e caros, as peças com maior quantidade de matéria-prima com conteúdo renovável, as mais pesadas, as mais baratas, entre outras características.

Os resultados ambientais das atividades humanas ao longo dos anos emergiram como uma das causas mais notáveis ​​das mudanças no clima no planeta. Diversos efeitos climáticos estão diretamente relacionados a essas mudanças, um dos mais perceptíveis é o aumento da temperatura, que vem gerando impacto significativo na vida na Terra. A capacidade adaptativa é uma das questões mais importantes para a diminuição dos perigos do aumento da temperatura. Neste contexto, o desenvolvimento de soluções adaptativas deve levar em consideração não apenas a mitigação dos efeitos das mudanças climáticas, mas também a diminuição de suas causas. Dispositivos que utilizam a energia elétrica tem sido considerado as soluções mais comuns encontradas para se adaptação ao calor, mas estes requerem recursos que implicam em mudanças climáticas. Além disso, os sistemas de ventilação passiva existentes que reduzem a temperatura geralmente exigem mudanças na estrutura do edifício, o que não é facilmente acessível para todas as sociedades ao redor do mundo. Assim, este estudo propôs a implementação do Processo de Desenvolvimento de um Produto Biomimético no desenvolvimento de uma solução bioinspirada visando a melhoria do conforto climático, mitigando os efeitos do aumento da temperatura. A pesquisa foi concentrada no design e concepção de uma telha biomimética desenvolvida para ser utilizada em residências com o intuito de diminuir a temperatura interna das residências em pelo menos 1oC. Os resultados obtidos foram analisados ​​em comparação com o uso de condicionadores de ar mostrando a viabilidade técnica e econômica do produto desenvolvido.

Program pengabdian kemitraan masyarakat (PKM) ini bertujuan untuk melakukan pendampingan kepada mitra dengan memanfaatkan buah nanas sebagai bahan fermentasi untuk memperbaiki mutu aroma dan cita rasa kopi. Hal ini dilakukan berdasarkan hasil observasi awal yang dilakukan oleh tim pengusul yaitu : 1) Proses pengeringan kopi yang tidak seragam, dan 2) Mutu aroma dan cita rasa yang masih kurang bagus. Penyebabnya karena bahan kopi robusta yang dibeli ke petani memiliki tingkat mutu yang berbeda. Dampaknya, harga kopi menjadi rendah. Mitra PKM ini adalah Usaha Pucako Roastery di Kelurahan Amplas, Kota Medan. Metode pelaksanaan PKM ini dilakukan melalui dua tahapan utama yaitu: 1) Pembuatan bubur buah nanas, dan 2) Fermentase kopi menggunakan bubur nanas. Melalui PKM ini diharapkan terjadi perbaikan mutu aroma dan cita rasa kopi serta dapat meningkatkan penjualan mitra. Adanya enzim bromelin pada bubur nanas akan dapat menurunkan kadar kafein karena enzim ini mampu memecahkan senyawa yang mirip protein pada kopi.

This program is considered important because Indonesia educational system require the use of problem-based learning methods (case studies) and project-based learning. In this regard, French teachers at partner schools find it difficult to teach using these two methods. To apply these two methods, teaching materials that match the characteristics of the two methods used are needed. To solve this problem, We have tried to integrate problem and project based learning methods in a structured textbook. The textbook was obtained through collaboration between lecturers and vocational French teachers. The textbook have been tested in learning classes. Based on the results of the trial, teachers felt very helped by the textbook which was developed through the integration of problem-based learning methods and case studies. In this way, learning becomes more effective and easier to implement. The conclusion from the results of this activity is that the integration of problem and project-based learning methods which are realized in the form of textbooks is very appropriate for use in learning.
