Elements Influencing User Engagement in Social Media Posts on Lifestyle Risk Factors: Systematic Review
Authors: Yip Yan Yee , Makmor-Bakry Mohd , Chong Wei Wen
Published: August 2024

Background

The high prevalence of noncommunicable diseases and the growing importance of social media have prompted health care professionals (HCPs) to use social media to deliver health information aimed at reducing lifestyle risk factors. Previous studies have acknowledged that the identification of elements that influence user engagement metrics could help HCPs in creating engaging posts toward effective health promotion on social media. Nevertheless, few studies have attempted to comprehensively identify a list of elements in social media posts that could influence user engagement metrics.

Objective

This systematic review aimed to identify elements influencing user engagement metrics in social media posts by HCPs aimed to reduce lifestyle risk factors.

Methods

Relevant studies in English, published between January 2006 and June 2023 were identified from MEDLINE or OVID, Scopus, Web of Science, and CINAHL databases. Included studies were those that examined social media posts by HCPs aimed at reducing the 4 key lifestyle risk factors. Additionally, the studies also outlined elements in social media posts that influenced user engagement metrics. The titles, abstracts, and full papers were screened and reviewed for eligibility. Following data extraction, narrative synthesis was performed. All investigated elements in the included studies were categorized. The elements in social media posts that influenced user engagement metrics were identified.

Results

A total of 19 studies were included in this review. Investigated elements were grouped into 9 categories, with 35 elements found to influence user engagement. The 3 predominant categories of elements influencing user engagement were communication using supportive or emotive elements, communication aimed toward behavioral changes, and the appearance of posts. In contrast, the source of post content, social media platform, and timing of post had less than 3 studies with elements influencing user engagement.

Conclusions

Findings demonstrated that supportive or emotive communication toward behavioral changes and post appearance could increase postlevel interactions, indicating a favorable response from the users toward posts made by HCPs. As social media continues to evolve, these elements should be constantly evaluated through further research.

Authors: Lee Li-Yun , Tung Heng-Hsin , Liao George , Liu Su-Ju , Chen Zi-Yu , Yang Yea-Ru
Published: August 2024

BACKGROUND

Physical activity and appropriate nutrition are essential for older adults. Improving physical health and quality of life can lead to healthy aging.

OBJECTIVE

To investigate the long-term effects of smart multi-health promotion programs on the physical and mental health of older adults in communities.

METHODS

A quasi-experimental method was utilized to recruit 112 older adults voluntarily from a pharmacy in central Taiwan between April 2021 and February 2023.Participants were divided into an experimental group (n=64) receiving a multi-health promotion program and a control group (n=48) with no specific intervention. The study measured frailty, nutritional status, well-being, and quality of life using standardized tools such as the Clinical Frailty Scale (CFS), Mini-Nutritional Assessment-Short Form (MNA-SF), Well-being Scale for Elders (WSE), and the EQ-5D-3L. Data were analyzed using descriptive statistics, independent t-tests, Pearson correlation, and generalized estimating equations (GEE).

RESULTS

The experimental group outperformed the control group in muscle mass and strength. The GEE analysis revealed that the experimental group had a significantly higher quality of life at 12 weeks and 24 weeks. The groups showed no significant variations in frailty or well-being with time.

CONCLUSIONS

The study's findings highlight the practical benefits of interventions, including physical and social activities and nutritional support, in enhancing the quality of life and general physical health of the elderly.

Exploring Fit in an mHealth Effectiveness-Implementation Trial: A Qualitative Study (Preprint)
Authors: Jacobson Nora , Park Linda Sujin , Pulvermacher Alice Diane , Voelker Samantha Jane , Herzog Mallory Frances , Quanbeck Andrew Ryan
Published: August 2024

BACKGROUND

Implementation frameworks like the EPIS model emphasize the importance of the “fit” between an intervention and its context, which includes the needs of its target population, as well as the culture, resources, and capabilities of the implementing organization. Even though lack of fit is a major barrier to implementation, fit has not often been a focus of implementation research.

OBJECTIVE

This paper uses fit as a lens to examine the implementation of Tula, an mHealth app aimed at reducing risky drinking days among individuals meeting the criteria for mild to moderate alcohol use disorder, in a 3-arm (app alone; app plus peer mentoring; app plus health coaching) RCT.

METHODS

Semi-structured interviews with 18 trial participants and 7 Tula implementers were conducted. Trial participants were pulled equally from each arm of the trial, and represented participants who demonstrated both high and low engagement with the application. Implementers consisted of a project manager, 4 peer mentors, and 2 health coaches. Interviews with participants focused on their motivations, opinions, and experiences of the intervention and their perception of their drinking behavior following the intervention, including how their use of the app worked to change that behavior. Interviews with implementers were centered on their roles, theories of change, perceptions of intervention, and areas for improvement. All interviews were analyzed using rapid qualitative analysis with both deductive and inductive components.

RESULTS

We identified areas of both fit and misfit. For example, there was a good fit between implementers’ theories of change and participants’ description of how change occurred. Fit was improved by the versatility of the app, which allowed participants to customize their experiences. Conversely, misfit was noted in the app’s inability to cultivate connection for many participants and a disjunction between the role of peer mentors in the intervention and their broader professional ethos.

CONCLUSIONS

Focusing on fit provides a useful guide to enhance future iterations of the Tula app that lead to better sustainment of the intervention.

Authors: Buajaroen Hathaichanok , Portangtam Darin , Chankham wariya , Simalaotao Paisan , Sirisukpoca Ubonrat , Kongkamsook Monchai , Timtab Pantip , Sousengaee Tapanee
Published: August 2024

BACKGROUND

In Nakhon Pathom Province, residents who recovered from COVID-19 over the past 3-4 years have not been monitored for post-COVID-19 symptoms (Long COVID), resulting in a lack of necessary services.

OBJECTIVE

1)To study the issues, needs, and systems of nursing and continuous care for people living with post-COVID-19 in Nakhon Pathom Province.
2)To design and develop a database system for continuous monitoring and care of individuals with post-COVID-19 in Nakhon Pathom Province.
3)To develop guidelines for the continuous care of patients recovering from post-COVID-19 in the community at Nakhon Pathom Province.
4)To evaluate the effectiveness of the database system for continuous monitoring and care of individuals with post-COVID-19 in Nakhon Pathom Province

METHODS

Participatory action research.

RESULTS

Post-COVID-19 symptoms persist for approximately six months, with common symptoms including persistent cough and easy fatigue. Patients with post-COVID symptoms have reduced access to services, relying on symptomatic treatment at local healthcare facilities and utilizing telehealth nursing systems. They expressed a need for continuous care from professional nurses and village health volunteers. Consequently, healthcare guidelines for post-COVID-19 recovery were developed, consisting of five approaches: 1) self-care through digital information retrieval, 2) care via telehealth nursing systems, 3) physical healthcare services post-recovery, 4) mental health services post-recovery, and 5) continuous care for referral in case of post-recovery incidents. These guidelines were used to design a database system for continuous monitoring and care, which was evaluated as highly effective.

CONCLUSIONS

This research highlights the critical need for a proactive and comprehensive approach to managing post-COVID-19 care in Nakhon Pathom Province. By developing and implementing a database system for continuous monitoring and care, along with clear guidelines, the study effectively addresses the ongoing needs of individuals recovering from COVID-19. The integration of technology, along with continuous care provided by professional nurses and village health volunteers, is highly effective in improving the quality of care. The findings suggest that adopting these strategies and implementing supportive policies on data management and communication systems focused on home visits will significantly enhance health service management and better prepare the region for future public health challenges.

Published: August 2024

The Coronavirus Disease 2019 (COVID-19) is a worldwide outbreak disease caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2). Indonesia is the fourth most populous country in the world and is predicted to be affected significantly over a more extended period. Universitas Gadjah Mada (UGM) Academic Hospital is one of the COVID-19 referral hospitals located in the Yogyakarta Special Region, Indonesia. Since the early months of the pandemic, the hospital has prepared strategies to provide effective and efficient patient care. The focus has been safety for both patients and healthcare staff. Here, we will share our experiences activating a Hospital Incident Command System (HICS) as a hallmark for preparedness and response to the COVID-19 pandemic disaster so it can be adopted in other hospitals nationwide or worldwide. The HICS in the UGM Academic Hospital includes 1) surge capacity for isolation rooms, 2) infection prevention and control, 3) human resources, 4) continuity of essential health services and patient care, 5) communication, 6) logistics and management of supplies including pharmaceuticals, 7) essential support services, 8) case management system, 9) surveillance early warning and monitoring, 10) laboratory services, and 11) additional programs including community service programs. Based on our experiences, early preparedness with a proactive response, and adapting plans to local needs, the national and global current situation are the keys to managing patient care. Implementing all levels of the hierarchy of control infection and keeping the human resources adequate also could protect staff
The Effect of Bilateral Orchiectomy on Total Prostate Specific Antigen (TPSA) Levels in Prostate Adenocarcinoma Patients
Authors: Sp.U WIKAN KURNIAWAN
Published: August 2024

AbstractBackground: Hormonal therapy is one treatment option for prostate cancer. There are two main categories of hormone therapy: surgical therapy and non-surgical therapy.  Orchiectomy is the surgical method of hormone therapy; medication supplementation is the non-surgical method. Many kinds of indicators are used to track the advancement of patients with prostate cancer receiving hormone therapy. tPSA levels are one of the markers that are regularly evaluated.Methods: In this retrospective study, PSA levels in patients with prostate adenocarcinoma cancer were evaluated before and after bilateral orchiectomy.  Use the search terms "prostate cancer" and "orchiectomy" to find research subject data in the UGM Academic Hospital's medical records installation between 2020 and 2023. The study's findings will be shown in a graphic and statistical analysis while protecting the subjects' anonymity.Results: Most of the participants (n=18, 60.0%) have pre-orchiectomy tPSA level of more than 30 ng/mL, while only almost a quarter (n=7, 23.3%) of participants have post-orchiectomy tPSA level of more than 30 ng/mL. The two research groups (p<0.0001) before and after the orchiectomy procedure, significantly differ between the two research groups based on Wilcoxon paired sample test analysis.Conclusion: TPSA levels are considerably decreased by bilateral orchiectomy.
Educação do Campo e o (im) Pacto Nacional da Alfabetização na Idade Certa (PNAIC)
Authors: Ribeiro Simone , Albuquerque Andrea Serpa
Published: August 2024

Este texto tem como objetivo refletir sobre Política Pública de Educação, e nosso foco são os encontros e desencontros entre o PNAIC e a Educação do Campo. O que nos move nesta escrita são as conversas que temos travado tanto nos encontros de formação do próprio programa quanto aquelas levantadas em nossos grupos de pesquisa: Historicamente como tem se dado a formulação de políticas de educação implementadas no campo brasileiro e, em que sentido, o PNAIC rompe ou reafirma esta história? No campo brasileiro cujas condições de letramento e até mesmo de acesso à escola são muito diversas, como se estabelece este pacto? O pacto é pela alfabetização ou pela alfabetização na idade certa? Quais as perspectivas para a formação de professores através do PNAIC? Por ser um tema ainda recente no cenário da política pública de educação, nossa contribuição objetiva manter vivo o diálogo, talvez suscitando ainda mais questões. Mas acreditamos que um dos caminhos para efetivar a construção de políticas públicas com a participa- ção dos sujeitos aos quais elas se destinam seja este. Como diria Riobaldo, personagem criado por Guimarães Rosa, ainda nos admiramos e nos animamos com a boniteza do inacabamento humano: “O senhor... Mire veja: o mais importante e bonito, do mundo, é isto: que as pessoas não estão sempre iguais, ainda não foram terminadas – mas que elas vão sempre mudando”.
Jogos no ensino-aprendizagem da geometria no Pacto Nacional pela Alfabetização na Idade Certa
Authors: Carneiro Reginaldo Fernando
Published: August 2024

A utilização de jogos é uma possibilidade para retomar-se o ensino-aprendizagem da Geometria na escola básica, que até algum tempo atrás foi deixado em segundo plano. Assim, temos como objetivo, neste artigo, discutir algumas possibilidades e limites do jogo no ensino-aprendizagem de Geometria a partir do material de matemática do Pacto Nacional de Alfabetização na Idade Certa – PNAIC. Para tanto, apresentamos algumas reflexões sobre o caderno Jogos na alfabetização matemática que traz cinco jogos para o ensino de Geometria: Na direção certa, Trilha dos sabores, Jogo das figuras, Dominó geométrico e Equilíbrio geométrico. Esses jogos permitem trabalhar diversos direitos de aprendizagem e abordam os conteúdos de localização, deslocamento, lateralidade, conhecimento do espaço, figuras geométricas, sólidos geométricos, suas características, etc. Além disso, na proposta de utilização dos jogos, observamos algumas atividades, como os constantes questionamentos em todos os momentos do jogo, a necessidade de avaliação e a escrita de relatórios que podem levar a perda da ludicidade, da motivação e do interesse da criança pelo jogo.
Educ(ação) na sala de aula regular
Authors: Marques Luciana Pacheco , Antunes Katiuscia C. Vargas
Published: August 2024

A proposta deste artigo é propor uma reflexão sobre a educ(ação) na sala de aula regular, problematizando a maneira como a educação vem se organizando no que tange aos seus objetivos, ao processo ensinoaprendizagem, à relação professoraluno, à prática pedagógica e à avaliação. Pretendemos inicialmente discutir essas questões à luz da abordagem tradicional, posto que para poder superá-la e caminhar na direção da educação inclusiva é necessário primeiro conhecê-la e compreendê-la como intrínseca à nossa prática, uma vez que nos constituímos professores e professoras imersos nesta perspectiva. Posteriormente, apresentamos outra perspectiva que indica uma caminhada inclusiva, lembrando sempre que todo caminho só acontece no seu saberfazer cotidiano e que cada escola é única em sua construção coletiva com seus professores e suas professoras, alunos e alunas.
As Tecnologias da Informação e da Comunicação (TIC) na educação para todos
Authors: Souza Amaralina Miranda
Published: August 2024

Ao refletir sobre a utilização da tecnologia na educação, devemos considerar a colaboração que a educação dá às melhorias sociais e como a tecnologia é importante como instrumento para alcançar estes fins, desde que seus usuários se utilizem dela para conduzir finalidades e valores adequados à sua realidade. Nesse sentido é necessário pensar uma escola que, efetivamente, acolha a todos os alunos e seja administrada de uma forma a favorecer os diferentes processos de ensino e de aprendizagem. O sucesso do processo educacional está diretamente ligado à possibilidade de se reconhecer as diferenças que existem na sala de aula e aceitá-las, respeitando estas diferenças e oportunizando os recursos necessários para que todos os alunos tenham acesso a todos os níveis de ensino. Esse artigo traz reflexões sobre o uso das tecnologias como apoio ao trabalho do professor para responder à diversidade de demandas educacionais dos alunos. Apresenta considerações sobre as Tecnologias Assistivas (TA) e o Software Educativo (SE) Hércules e Jiló, construídos para apoiar o trabalho do(a) professor(a) na construção de novas estratégias pedagógicas, voltadas para o atendimento às necessidades educacionais específicas de todos os alunos.
¿Cómo podemos comprender la filosofía de la educación?
Authors: Meza Marisa
Published: August 2024

Hoje podemos observar um retrocesso, geralmente dramático, da presença da Filosofia da Educação na formação de professores. Este fenômeno possui razões políticas e econômicas que parecem agravar-se por uma sistemática mudança de nome das poucas atividades acadêmicas presentes no currículo de formação de professores que em outros tempos haveríamos chamado de Filosofia da Educação, mas que hoje não tem esse nome, Se trata de uma mudança involuntária ou casual de nomes ou existe uma tentativa de distanciar em relação a certos conceitos existentes com relação ao que a Filosofia da Educação é? Como podemos entender a Filosofia da Educação? Este trabalho pretende ser responsável especialmente da ultima pergunta e, em forma tentativa, da primeira, realizando um diálogo crítico com as compreensões da Filosofia da Educação de alguns clássicos com Richard S. Peters y Terry W. Moore, e outros filósofos e filósofas como Nel Noddings, María García Amilburu y John White.
Um exercício que faz escola: notas para pensar a investigação educacional a partir de uma experiência de formação no Rio de Janeiro
Authors: Kohan Walter Omar
Published: August 2024

O presente trabalho apresenta uma experiência prática de formação no campo da filosofia da educação realizada junto com Jan Masschelein (Universidade Católica de Louvain); Wim Cuyvers, Jorge Larrosa (Universidade de Barcelona) e Maximiliano López (Universidade Federal de Juiz de Fora), além de setenta estudantes, entre belgas e brasileiros. Situo a experiência, descrevo seu marco teórico e metodológico e analiso alguns dos trabalhos resultantes dela. O eixo central do exercício é o conceito escola, ressignificado a partir de sua etimologia, como a materialização do tempo livre (skholé). Nesse sentido, a escola compreende quatro dimensões: separação (do tempo afirmado nos campos social, econômico e político); profanação (dos sentidos socialmente consagrados ou naturalizados); atenção (que torna o mundo interessante) e amor público (pelas coisas do mundo e o mundo como tal). Depois de tecer algumas considerações sobre o valor do exercício, apresento – apenas a título de primeira elaboração sobre o tema – o conceito de escola nômade.
La Bildung de Simón Bolívar. Notas Preliminares
Authors: Villegas Gregorio Valera
Published: August 2024

En este trabajo se realiza un estudio sobre el proceso formativo de Simón Bolívar desde la perspectiva de su bildung; valga decir, de su trayectoria, el ir de camino por los senderos que transitó, en su llegar a ser el que llegó a ser. Para ello hemos tomado como referentes fundamentales a sus viajes de formación. Se trata, metodológicamente hablando, del despliegue de una fenomenología hermenéutico crítica de la bildung orientada por el viaje de formación; con miras, entre otras cosas, a bocetar una relación de narración / formación, especialmente referida a la formación intelectual de la persona / personaje llamado Simón Bolívar. Entre los objetivos pueden destacarse: realizar un análisis interpretativo, fenomenológico/hermenéutico, de la invención histórica de un sujeto; desarrollar una mirada de su bildung a partir de unos hitos referenciales conformados por los viajes de formación realizados y la subsecuente metamorfosis sufrida. Como uno de sus principales aportes está la interpretación del viaje de formación como elemento fundamental de la bildung de Bolívar.
Montaigne: filosofia e educação para a vida
Authors: Lemgruber Márcio Silveira
Published: August 2024

A partir de um levantamento em diversos livros de história da educação, de autores nacionais e estrangeiros, procuro analisar o lugar neles ocupado por Michel de Montaigne, ou seja, quais os principais aspectos de suas ideias são enfatizados em cursos de formação de professores. Concluo que as ideias mais estritamente pedagógicas dos Ensaios, expressas nos capítulos Pedantismo e Da educação das crianças, têm uma razoável divulgação. Entretanto, outras formulações como as epistemológicas ou acerca da diversidade cultural, que poderiam ser muito estimulantes para a formação do futuro docente, pouca ou quase nenhuma presença têm naquelas obras.
Ludicidade e formação da criança no primeiro ano do ensino fundamental
Authors: Bonfim Patrícia Vieira , Pereira Lucia Helena Pena
Published: August 2024

No intuito de analisar os desafios enfrentados pela criança de seis anos ao ingressar no Ensino Fundamental, este artigo apresenta alguns dos resultados de uma pesquisa realizada em escolas públicas de uma cidade mineira. O referencial teórico baseou-se em literatura que considera as atividades lúdicas como aquelas que possibilitam o envolvimento pleno e criativo da criança, favorecendo o seu desenvolvimento integral. Os resultados permitiram apontar que o brincar e o aprender são vistos como ações opostas na escola; há muitas dúvidas da comunidade quanto à ampliação do ensino obrigatório brasileiro e de como atuar nos anos iniciais, e que, cada vez mais, o lúdico tem ficado em plano secundário nas práticas pedagógicas.
Preencher Potências e Inventar Educações Possíveis: pela experimentação de uma Formação-Sem-Órgãos
Authors: Mossi Cristian Poletti , De Oliveira Marilda Oliveira
Published: August 2024

O artigo busca, a partir da frente filosófica instaurada por Deleuze e Guattari na obra Mil Platôs (1995a, 1995b, 1996, 1997a, 1997b), pensar o campo educativo – o qual implica nas relações entre corpos, espaços, práticas, metodologias – como um fenômeno de estratificação de agenciamentos territoriais. Desse modo, a prática do Corpo-sem-Órgãos, enunciada por Artaud (Para acabar com o julgamento de Deus, 1947) e evidenciada também por Deleuze e Guattari em Mil Platôs, pode se tornar cara no sentido de gerar alguns movimentos de desterritorialização/desestratificação dos agenciamentos territoriais estratificados que formam o campo educativo. Isso implica pensar em pequenas educações, enquanto práticas marginais, que se alojam em uma grande Educação, já deveras instituída e legitimada, possibilitando aos corpos envolvidos em tais processos o “preenchimento de uma potência” (DELEUZE, 1988/1989, s/p) que lhes confere alegria produtiva e inventiva. Por fim, o artigo problematiza uma educação/formação sem órgãos que desinstitui as relações entre aprendizes, docentes e espaços educativos de formação de uma relação hierárquica, intentando tramar desvios sinuosos dos caminhos incessantemente pisados, invencionando outros percursos que se distanciam de receituários e identidades fixas.
Inspetor de Ensino e Diretor Escolar na Legislação Educacional de Minas Gerais (1906–24)
Authors: Ribeiro Betânia Oliveira Laterza , Carvalho Luciana B. O. B. , Oliveira Sandra M.
Published: August 2024

Na primeira República (1889–1930), a legislação possibilitou pensar na organização da educação. As reformas se proliferaram país afora, institucionalizado um modelo de escola para um modelo de cidadão. Institucionalizar supôs controlar e hierarquizar a administração do grupo escolar pela ação do inspetor de ensino e do diretor. Este estudo verifica a constituição e o surgimento desses agentes em leis e decretos da legislação mineira. Tomados aqui tomados como fontes históricas, são lidos no campo da gênese das políticas educacionais e da organização e do funcionamento do grupo escolar. O estudo objetiva analisar tanto o efeito da força político-legal na administração e estruturação técnico-pedagógica para controlar a ação escolar quanto seus reflexos no ensino primário, sobretudo de Minas. Os resultados mostram que os cargos de inspetor (criado em 1835) e diretor (criado em 1906) deviam ser exercidos por homens; e que sua atividade fiscalizadora previa fazer a escola funcionar, fiscalizar tal funcionamento e atestá-lo mediante documentos para o governo. O estudo mostra que a ação desses sujeitos supunha outros conhecimentos que não os pedagógicos e administrativos. Mais que isso, reforça a ideia de centralização das decisões educacionais a ser tomadas com base em documentos da burocracia escolar que faziam a interface do governo mineiro com a escola.
Enactaciones de la educación matemática crítica en Colombia
Authors: Valero Paola
Published: August 2024

Al investigar las investigaciones que se presentan en los seis artículos que conforman el número especial sobre la Educación Matemática Crítica (EMC) en Colombia, se han identificado las resonancias y diferencias en las condiciones y problemas de estudio de tales seis investigaciones. En una primera instancia, el ejercicio analítico sobre los textos permitió identificar unas generalidades sobre las intenciones, problemas de investigación, referentes teóricos y metodologías presentes en los estudios. En un segundo momento se identificaron dos enunciados que circulan en las investigaciones. El primero tiene que ver con los efectos de poder presentes en las prácticas educativas en matemáticas cuando se adopta una visión disciplinar de las matemáticas como punto de partida orientador de los procesos educativos. El segundo tiene que ver con la configuración del deseo de gobierno a través de las matemáticas como parte de procesos políticos y económicos en la sociedad. En su conjunto los resultados del análisis de los textos muestran los puntos ciegos de tales estudios y también las potencialidades para futuras enactaciones de la EMC en Colombia y en otros países en América Latina
The mathematical pattern of the shroud in the mortuary bundle of Zimapán, Hidalgo
Authors: Galán Tamés Mariana , Mainou Luisa , Gómez González Judith , Aguilar Romero Ariana
Published: August 2024

Among other material remains found in a burial from a rock shelter in Zimapán, the shroud that wrapped a pre-Hispanic individual presents a distinctive pattern that is not noticeable to the naked eye. One of its most interesting elements is the mathematical thinking behind this which is repeated throughout the entire textile as the main motif. The main objective of this article is to analyze the mathematical and geometric aspects of the shroud’s weaving technique.
Categories of analysis will include plane geometry (polygons and angles), transformational geometry (translations, reflections, and rotations), graph theory, the minimal motif, and the generating system. The analysis will also include reflections on the constructive logic of this textile piece, for example under the notion of measurement and its reproduction. These observations can also contribute to research on the identification of different traditions of weaving and subsequent comparative analyses between different pieces.
Saberes Matemáticos Ancestrales: una mirada Etnomatemática al tejido en lana de ovejo
Authors: MORALES PEÑA JHOM JAIRO
Published: August 2024

Este trabajo nació como respuesta a la desarticulación entre los conocimientos matemáticos escolares y las prácticas culturales desarrolladas en la comunidad indígena Yanacona de Caquiona, municipio de Almaguer, Cauca, Colombia.  Ante esta problemática, se buscó identificar Saberes Matemáticos Ancestrales (SMA) en el tejer lana de ovejo, desde una perspectiva sociocultural enmarcada en la Etnomatemática, con enfoque cualitativo y tejido metodológico etnográfico. La identificación de SMA implicó la participación del investigador en el ambiente natural de las tejedoras, a través de la ejecución de actividades como la negociación, acceso y trabajo de campo; utilizando la observación participante y la entrevista semiestructurada como técnicas para la obtención de la información. En ese sentido, entre los hallazgos se encontró que en la práctica de tejer están presentes SMA relacionados con actividades matemáticas universales como: medir, contar y diseñar (Bishop, 1999). También, se logró conceptualizar una noción de SMA a partir de un ejercicio de reflexión conjunta respecto a lo que las sabedoras consideran como matemático y ancestral dentro del tejido, reconociendo en ellas, no solo la capacidad de ejecución de una práctica, sino también, y principalmente, la capacidad de reflexionar frente a esta. Así mismo, se consiguió describir el proceso de elaboración de algunos tejidos en lana de ovejo, descubriendo que para tejer se desarrollan 6 etapas, y se develó que para la comunidad de Caquiona esta práctica es sinónimo de vida y tradición, y que contribuye a su sobrevivencia y trascendencia en el tiempo.
Posibilidades/límites del Aprendizaje y Servicio Solidario
Authors: Bruno Gustavo Nicolás , Ruiz-López Natalia
Published: August 2024

Desde una mirada latinoamericana, el Aprendizaje y Servicio Solidario (AySS) se entiende como un paradigma pedagógico y una filosofía de la educación. En el involucramiento de una institución educativa con la comunidad, la dimensión “aprendizaje” se retroalimenta con la dimensión “servicio”: el servicio dado-recibido tiene que ver con la calidad del aprendizaje y los conocimientos involucrados. Y la “solidaridad” no es un fenómeno vertical sino horizontal, un “hacer junto a” con mutuo beneficio, y con creación de vínculos comunitarios para abordar las necesidades conjuntas.
Como núcleo del trabajo de campo de una investigación doctoral, se desarrolló una experiencia de AySS en un Instituto de Educación Secundaria (IES), de Getafe (Madrid). Se trataba de un contexto de “estudiantes/profesores de clase media”, con “poca diversidad” étnica-lingüística-etc. No siempre objeto de interés desde una perspectiva Educación Matemática (EM) “para la justicia social/democracia/equidad/etc.”, desde iniciativas de Etnomatemática, o similares. Pero la escolarización matemática genera numerosas estratificaciones en la escuela y el sistema educativo, que se traducen en sistemas de acreditación, jerarquización y poder simbólico en las sociedades capitalistas modernas. Y el grupo de estudiantes/profesores e investigadores involucrados en esta experiencia son parte de tal maquinaria de selección/acreditación/exclusión.
La experiencia consistió en investigar y proponer juegos y actividades matemáticas para residencias de personas mayores, que formarían parte, con ayuda de los terapeutas de las residencias y acuerdo de los directores, de las actividades de terapia ocupacional previstas en las residencias, para estimulación cognitiva. En este artículo se ofrecen algunos resultados de esta investigación. Se referirán resultados en tanto que sentidos-eventos emergentes desde las entrañas del AySS, analizando las posibilidades y límites que nos ofrece este paradigma para abordar algunas inquietudes de investigación desde una perspectiva sociopolítica en EM.
ON QUANTUM CODES CONSTRUCTION FROM CONSTACYCLIC CODES OVER THE RING I_q[u,v] /
Authors: Ali Shakir , Sharma Pushpendra
Published: August 2024

This paper focuses on studying the properties of constacyclic codes, quantum error-correcting codes. The code is studied over a specific mathematical structure called the ring $\mathfrak{S}$, which is defined as $\mathfrak{S}=\mathfrak{I}_q[\mathfrak{u},\mathfrak{v}]/\langle \mathfrak{u}^2-\alpha^2,~ \mathfrak{v}^2-\alpha^2,~\mathfrak{u}\mathfrak{v}-\mathfrak{v}\mathfrak{u} \rangle$, where $\mathfrak{I}_q$ is a finite field of $q$ elements, $\alpha$ be the nonzero elements of the field $\mathfrak{I}_q$ and $q$ is a power of an odd prime $p$ such that $q=p^m, ~\textup{for}~ m \ge 1$. The paper also introduces a Gray map and use it to decompose constacyclic codes over the ring $\mathfrak{S}$ into a direct sum of constacyclic codes over $\mathfrak{I}_q$. We construct new and better quantum error-correcting codes over the ring $\mathfrak{S}$ (cf.; Table 1 and Table 2). Moreover, we also obtain best known linear codes as well as best dimension linear codes (cf.; Table 4).
PENERAPAN SYARIAT ISLAM DI ACEH DAN TANTANGAN DI ERA EKONOMI DAN POLITIK LIBERAL
Authors: Yusran Hadi Muhammad
Published: August 2024

Since its declaration on 1 Muharram 1423 H or coinciding with 15 March 2002, Islamic law in Aceh has been under the spotlight. Islamic Sharia, which was revealed by Allah Swt, should be understood as a perfect rule and become rahmatan lil'alamin, instead it gets opposition from some Muslims who are secular and anti-sharia. Some Muslims today, especially leaders and intellectuals in Aceh who claim to be critical but do not have adequate knowledge about Islamic law, dare to reject God's law (sharia). Various negative issues and shubhat are put forward. Among other things, Islamic sharia in Aceh is not in accordance with human nature. In addition, the implementation of sharia in Aceh is said to have been hasty, without careful thought and preparation. This paper attempts to refute these allegations. Whether we realise it or not, negative accusations against the implementation of Islamic sharia in Aceh not only destroy Islamic sharia itself, but also go against the law of God (Allah Swt) and human nature. The accusation that Islamic law in Aceh is incompatible with human nature is a fallacy. Islamic Sharia in Aceh, wherever and whenever, is in accordance with human nature. With Islamic law, human beings discover their nature as servants of Allah and caliphs on earth. Therefore, Islamic law was revealed to guide and protect this human nature so that it does not deviate and is not tyrannised. In addition, this paper also refutes the accusation that Islamic sharia in Aceh was implemented in a hurry. In fact, Islamic sharia in Aceh has been implemented since ancient times, the time of the kingdom of Aceh. However, the implementation of sharia at this time was carried out in stages. That is why, in the beginning, its scope was only limited to certain areas. For example, in criminal law only applies to jarimah khamar, gambling and khalwat / adultery with ta'zir punishment. The next stage is the application of hudud punishment in the case of jarimah hudud. This is the concept of tadarruj that characterises Islamic law itself.

Telematic services that require low latency for real-time applications and that make use of wireless mobile networks are increasingly popular. In the case of Tele-Surgery services that employ Live Video Streaming (LVS), latency times of the order of 1ms are needed. Given the difficulty of implementing real 5G test scenarios that enable this type of service to be characterized, this paper presents an emulation scenario that uses Simu5G to simulate the network, Wowza as a real video server, OBS Studio for transmission and VLC media player for content playback. This emulation scenario makes it possible to modify such parameters as bitrate, bandwidth, frequency and numerology index in order to evaluate different network configurations. By varying these parameters in a controlled way, packet losses are obtained for different bitrate values. The best quality video was obtained with a bitrate of 3000 Kbps.

Globalizacja ekonomiczna przyspiesza przepływy czynników wytwórczych w skali krajowej i globalnej. W rezultacie roną jednak koszty transakcyjne funkcjonowania systemów gospodarczych i pojawia się koniecznośc wprowadzenia nowych mechanizmów ich optymalizacji i kontroli. Dotyczy to w szczególności sektora rolno-żywnościowego, który odgrywa kluczową rolę w zrównoważonym rozwoju gospodarki rynkowej. Pojawia się ważne pytanie, czy w tych warunkach czynnik ziemi jest zdolny do generowania rent ekonomicznych, które stanowiłyby przesłankę przewag komparatywnych?jednej strony, ricardiańskie renty gruntowe zanikają, renty ekonomiczne według doktryny H. George’a wywołują kryzysy finansowe, a założenia monetarystyczne okazują się niewystarczające. Z drugiej strony czynnik ziemi zyskuje nowe zastosowania w zakresie usług środowiskowych, które pozwalają założyć, że renty gruntowe mają źródło w przepływach realnych.Celem opracowania jest ukazanie ewolucji teorii renty gruntowej od czasów ekonomii klasycznej do dzisiaj. Podjęto w nim próbę sformułowania koncepcji renty gruntowej adekwatnej do procesów zachodz??cych we Wspólnej Polityce Rolnej Unii Europejskiej, ukierunkowując ją na czynniki instytucjonalne. Stawia się też, że renta instytucjonalna należy do najtrwalszych rent ekonomicznych, zważywszy na kierunek rozwoju, który obrało europejskie rolnictwo

Wspólna Polityka Rolna a ubezpieczenia gospodarcze w rolnictwie polskim
Authors: Wicka Aleksandra , Wojciechowska-Lipka Ewa
Published: August 2024

Celem opracowania jest przedstawienie ewolucji ubezpieczeń w rolnictwie w Polsce oraz omówienie aktualnego systemu ubezpieczeń obowiązkowych ze szczególnym uwzględnieniem obowiązkowych ubezpieczeń upraw. W artykule przedstawiono podstawy prawne, najważniejsze uwarunkowania budżetowe oraz zakres korzystania z ubezpieczeń upraw. Zwrócono także uwagę, iż na popyt na ubezpieczenia produkcji roślinnej wpłynęły przede wszystkim zmiany w przepisach wspólnotowych i krajowych a w małym stopniu wzrost świadomości ubezpieczeniowej rolników. Wprowadzenie nowych uregulowań może także przesunąć wydatki budżetu z wypłat odszkodowań związanych z klęskami na wypłaty dotacji do polis ubezpieczeń.

Celem podjętych badań była ocena efektywności ekonomicznej oraz określenie roli dopłat wyrównawczych ONW w kształtowaniu dochodu gospodarstw owczarskich prowadzących produkcję w różnych warunkach przyrodniczych. W badanych obiektach obszary ONW w zależności od regionu stanowią od 51,22% do 78,37% ogółu użytków rolnych jakie posiadają gospodarstwa. Nie zależnie od regionu, w którym utrzymywano owce, sprzedaż żywca oraz innych produktów owczarskich w strukturze przychodów stanowiła zaledwie około 20 %.Zdecydowany wpływ na poprawę sytuacji ekonomicznej gospodarstw miały dopłaty wyrównawcze do obszarów o niekorzystnych warunkach gospodarowania. Stanowiły one od 4,41 % w strukturze przychodów dla regionu południowego do 6,04 dla regionu północno – wschodniego. Analizując dochodowość gospodarstw, stwierdzono, iż dzięki dopłatom ONW dochody rolników wzrosły o około 29,56%.Reasumując należy podkreślić, iż uzyskiwane dopłaty oraz dotacje przez badane gospodarstwa w głównej mierze decydowały o dodatnim wyniku ekonomicznym prowadzonej działalności rolniczej.
Progressive resistance exercise training of the hypotrophic quadriceps muscle in man. The effects on morphology, size and function as well as the influence of duration of effort
Authors: Ingemann-Hansen T Halkjaer-Kristensen J.
Published: August 2024

The effects of progressive resistance exercise (PRE) training for 4 weeks on the hypotrophic quadriceps muscle were investigated in 23 young healthy male soccer players, who had been immobilized in a plaster cast 4-6 weeks after knee ligament injuries. The subjects were allocated to two training regimes where the injured leg was trained for periods of varying duration, whereas the intensity and frequency of exercise were alike in the two groups. However no significant differences were detected between the two training groups. In the whole material the lean thigh volume of the injured leg increased from 4.09 to 4.47 litres (p less than 0.001), whereas the fat component of the thigh was unchanged. The dynamic strength (1 RM) of the injured leg increased from 14.0 kg to 27.0 kg and amounted to 87% of the control leg after 4 weeks of training. At this time the maximum isometric strength amounted to 114 Nm, which was 63% of strength in the control leg. Succinate dehydrogenase (SDH) in homogenates of muscle biopsy sample increased (i.e. 20%, p less than 0.05) to the same level as found in the control leg. No changes in phosphofructokinase (PFK) were observed. The type I fibre distribution was lower in the immobilized leg than in the control leg. These results indicate that, following muscular hypotrophy resulting from 4-6 weeks of immobilization, dynamic exercise can restore the oxidative potential, whereas the size and strength are only partly recovered.
Strengthening of human quadriceps muscles by cutaneous electrical stimulation
Authors: McMiken DF Todd-Smith M
Published: August 2024

The effectiveness of cutaneous electrical stimulation as a muscle-strengthening technique was evaluated by comparison with an isometric regime. Sixteen normal healthy subjects were randomly assigned to either an electrical group or an isometric group. A pretest was given of maximum voluntary force in the quadriceps (extensor) muscles, measured with a cable tensiometer. Subjects then trained (isometrically or by electrical stimulation) four days per week for three weeks. Training by electrical stimulation was via a square-wave pulse (75 Hz and 0.1 ms) with the voltage determined by subject tolerance for ten, 10-sec induced contractions (with 50-sec rest intervals). Isometric training consisted of ten, 10-sec maximal contractions (with 50-sec rest intervals) at each session. Feedback of the generated force was standardised for both groups. Post-training measures were then administered using the same protocol as the pretest. Both groups demonstrated a marked improvement in quadriceps strength of 22 +/- 5.3% for the electrical group and 25 +/- 6.9% increase for the isometric group (p less than 0.02). The change in strength was apparently not dependent on the magnitude of the stimulating voltage (5-10 V) nor on the tension induced. There was no significant difference in the strength gains achieved by the two regimes (p greater than 0.05). No pain, muscle lesions or other ill effects were observed with electrical stimulation. We conclude that cutaneous electrical stimulation is a viable strengthening technique. There are obvious practical applications of this technique to the rehabilitation of patients who are not able to maintain an effective voluntary contraction.

Budaya Betawi seiring waktu semakin kehilangan makna di dalam nya dikarenakan arus urbanisasi yang pesat dan mengakibatkan masuknya kebudayaan baru ke Jakarta yang tentunya berpengaruh kepada eksistensi dari etnis Betawi ini sendiri yang perlahan hilang dan tidak dapat dipungkiri perkembangan zaman secara konsisten terjadi dari waktu ke waktu, yang mengakibatkan kehilangan identitas budaya lokal serta kurangnya wadah serta lingkungan yang sama-sama membangun upaya pelestarian kebudayaan etnis Betawi yang tentunya merujuk kepada identitas budaya maka tujuan dari penelitian ini adalah untuk mengetahui dinamika dan transisi dari permasalahan krisis identitas etnis Betawi, apa sajakah yang menjadi tantangan dalam menghadapi krisis identitas etnis Betawi serta upaya apa sajakah yang dapat dilakukan untuk menghadapi krisis identitas budaya tersebut. Penelitian ini menggunakan pendekatan kualitatif dengan pendekatan deskriptif, dan fokusnya adalah modifikasi sebagai respons terhadap krisis budaya, yang tentunya akan disesuaikan seiring berjalannya waktu, dalam pengumpulan data tersebut menggunakan Teknik triangulasi sehingga kesimpulannya merujuk kepada dinamika dan transisi dalam permasalahan krisis identitas etnis Betawi secara nyata terlihat, Jakarta terus berkembang sesuai dengan gaya pembangunan kota modern dunia. Hotel, apartemen, dan mal berlomba-lomba membangun tiang beton, yang akhirnya menghancurkan perkampungan Masyarakat lokalnya. Masyarakat Betawi dan semua aspek budaya tradisionalnya secara bertahap tetapi pasti terpengaruh oleh modernitas jadi urbanisasi dan perkembangan zaman di era globalisasi juga menjadi tantangan dalam menghadapi krisis identitas tersebut untuk itulah modifikasi budaya menjadi upaya kuat dalam menghadapi krisis identitas karena sesuai dengan zaman saat ini dan menyesuaikan juga dengan generasi saat ini tanpa menghilangkan nilai asli dalam budaya tersebut.
