Agarolytic bacteria produce agarase, which may aid in the growth of cultured tropical abalone fed natural seaweed. Agarolytic bacteria can come from a variety of sources, such as seawater, abalone intestines, and dead seaweed. This study aimed to isolate, screen, describe, and identify agarolytic bacteria found in red macroalgae. Agarolytic bacteria isolated from Gracillaria segregated from the substrate at Drini Beach, Gunungkidul Regency, were qualitatively described using the agarolytic index, antibiotic susceptibility, acid resistance (pH 4), and safety test. We collected seven agarolytic isolates. FRAgK1 isolate had the highest agarolytic index, was sensitive to antibiotics, resistant to low pH conditions, and non-pathogenic to finfish, making it suitable for use as gut probiotics in abalone. The bacterium was short rod-shaped, Gram-positive, non-motile, lacked catalase and indol, and was unable to ferment lactose or sucrose. The 16S rRNA gene sequence of FRAgK1 was most similar to Bacillus subtilis, however only by 99.43%.

Authors: Rizal Muhammad
Published: January 2025

The goal of this study was to evaluate the use of BSF larvae meal and oil as feed components in order to determine their impact on Litopenaeus vannamei shrimp growth performance, nutritional composition, and health response. Three shrimp ponds, each with a diameter of 20 m, were stocked with 72,000 Litopenaeus vannamei post larvae (PL-8), resulting in a stocking density of 229 shrimp per square meter. The trial diets comprised three types: control diet (K), diet containing BSF larvae meal (A), and diet containing BSF larvae meal plus oil (B). The parameters observed in this study included shrimp growth and productivity, feed consumption, feed conversion ratio (FCR), survival rate, nutritional composition (proximate, amino acid profile and fatty acid profile), total bacteria in the shrimp's digestive tract, and total hemocyte count in the shrimp's hemolymph. It was found that subtituting fish meal with 34% BSF larvae meal did not affect the growth performance of shrimp raised in shrimp ponds, compared to the control treatment. The assessment of the amino acid profile has revealed minimal variation between treatment. Nevertheless, both treatments A and B exhibited a decreased concentration of unsaturated fatty acids, specifically omega-3 and omega-6, in comparison to control. Meanwhile, treatment B had the highest levels of saturated fatty acid and omega-9 fatty acid content.

Perbandingan Survei LiDAR Menggunakan Wahana Drone dan Handheld-SLAM Untuk Analisa Tree Trunk dan Tree Crown
Authors: Rahmadani Putri
Published: January 2025

Rekonstruksi tiga dimensi pohon memiliki peran penting dalam berbagai bidang, seperti studi pengelolaan hutan, ekologi, perhitungan emisi karbon, serta aplikasi perencanaan perkotaan. Namun, metode tradisional yang telah digunakan selama bertahun-tahun umumnya membutuhkan tenaga kerja intensif, memakan waktu lama, dan rentan terhadap kesalahan pengukuran. Untuk mengatasi kendala ini, metode berbasis point cloud mulai digunakan sebagai solusi yang lebih efektif. Point cloud tersebut dapat dihasilkan melalui teknologi LiDAR maupun fotogrametri. Teknologi LiDAR biasanya diintegrasikan dengan drone sebagai wahana untuk pengambilan data. Namun, dalam beberapa tahun terakhir, penggunaan LiDAR berbasis handheld-SLAM (Simultaneous Localization and Mapping) telah menjadi alternatif metode survei modern. Handheld-SLAM LiDAR adalah perangkat LiDAR yang dilengkapi dengan teknologi SLAM, memungkinkan pemindaian tiga dimensi secara real-time. Penelitian ini akan membandingkan dua metode akuisisi data, yaitu menggunakan drone LiDAR dan handheld-SLAM LiDAR, yang akan diaplikasikan untuk analisis karakteristik pohon, seperti bentuk tajuk (tree crown) dan batang pohon (tree trunk). Hipotesis awal penelitian ini adalah bahwa sensor LiDAR pada drone memiliki keterbatasan dalam merekonstruksi bentuk tiga dimensi pohon, khususnya pada bagian batang, karena akuisisi data yang dilakukan dari atas. Dengan adanya teknologi handheld-SLAM LiDAR, diharapkan keterbatasan tersebut dapat diatasi, sehingga menghasilkan pemodelan pohon yang lebih akurat. Lokasi survei penelitian ini adalah sebagian kecil area Taman Hutan Raya di Bandung, dengan tutupan lahan yang terdiri dari pepohonan. Akuisisi data dilakukan menggunakan dua perangkat LiDAR: handheld LiDAR SATLAB Lixel X1 dan DJI Zenmuse L1 yang diterbangkan menggunakan DJI Matrice 300RTK. Data yang diperoleh dari kedua alat ini kemudian diolah menggunakan perangkat lunak pengolah point cloud untuk menghasilkan data bebas noise. Hasil pengolahan ini digunakan untuk menganalisis karakteristik pohon, termasuk tree crown  dan tree trunk. Penelitian ini diharapkan dapat menyimpulkan perbandingan efektivitas kedua metode akuisisi LiDAR dalam merekonstruksi bentuk nyata pohon, serta menunjukkan sejauh mana data dari kedua metode tersebut dapat diintegrasikan untuk menghasilkan model pohon yang lebih akurat dan komprehensif.

Published: January 2025

Indonesia has entered the ageing population phase, marked by the percentage of older individuals exceeding 10 per cent and continuing to rise. Older individuals are more vulnerable to various factors, such as economic non-productivity, declining health conditions, and the need for companionship. Happiness among older individuals is important because productive, healthy, and happy older individuals may become a second demographic dividend for the country’s development. By utilising the Happiness Index Survey (SPTK) 2021 data, this study aims to measure the happiness of Indonesian older individuals and identify the sociodemographic, socioeconomic, health, and social engagement factors associated with it. The happiness index for older individuals in Indonesia is estimated to be at 70.54 points, with 49.3 per cent of them having a happiness index above this number, categorised as happy, and 50.7 per cent falling into the less happy category. Binary logistic regression identifies significant factors associated with happiness among older individuals. These include marital status, education level, type of residence, household income, employment status, ownership of old-age security, non-presence of chronic diseases and disabilities, and frequency of communicating with family. Gender is not significantly associated with happiness among older individuals. Various interventions from stakeholders are crucial to enhance the happiness of older individuals, primarily to protect them from vulnerabilities. These include health protection, empowerment, welfare assurance, and social support for older individuals with limited social relationships.

Authors: B P Aparna
Published: January 2025

Slag is one of the non metallic product which is formed in the manufacture of pig iron and steel in blast furnace. The
constituents of slag are silicates of calcium, manganese and aluminium in different compositions. The molten slag is insoluble
having lower density and floats on the pig iron. Slag is one of the essential by product obtained in the manufacture of iron,
which is considered as the industrial waste product. But this waste product will be considered as one of the useful product in the
construction industry. Hence this slag can be used as alternative material for coarser aggregates and finer aggregates in
construction activities. The study can be carried out by partial replacements of steel slag for fine aggregates to know the concrete
strength parameters. The different types of steel slag are listed below: Blast furnace slag (BFS) and steel furnace slag (SFS) are
being use as an industrial by product. For the cement composites and cementitious components of concrete, Ground granulated
blast furnace slag (GGBS) has been used. BFS and SFS have distinctive chemical and physical properties hence they are well
suited for use in various construction and civil engineering projects Air-cooled BFS provides a strong aggregate that can be used
in the production of concrete, Portland cement as well as asphalt-concrete. Water Cooled slag with gives lightweight aggregates
which can be uses in the production of masonry blocks and lightweight concrete. Pelletized & granulated BFS are grouted and
used in production slag cement. S

Published: January 2025

Abstract: The classification of skin disease images is a vital application of deep learning, particularly through the utilization of
transfer learning techniques with models like EfficientNet. Transfer learning involves leveraging knowledge gained from a pretrained model on a large dataset and adapting it to a specific task, which is particularly advantageous when dealing with limited
labeled data. EfficientNet, known for its effectiveness in balancing model size and performance, serves as a powerful feature extractor. The initial layers capture general features from images, and by fine-tuning the later layers, the model can be tailored to
the nuances of skin disease classification. This adaptation allows for efficient learning of relevant patterns in dermatological
images. To enhance model generalization, data augmentation techniques are applied during training. This involves introducing
variations in the training data, such as rotations and flips, to expose the model to a diverse range of scenarios. Additionally,
incorporating techniques to handle class imbalances within the dataset is crucial for unbiased learning. Validation during
training is vital to prevent overfitting, ensuring that the model generalizes well to unseen data. Evaluation metrics like precision,
recall, and F1 score provide a comprehensive understanding of the model’s performance, especially when dealing with
imbalanced datasets. In summary, the classification of skin disease images using transfer learning with EfficientNet involves
adapting a pre-trained model to the specific task of dermatological classification

Published: January 2025

In the course of the study, an improved model of the motion of a viscous lubricant in the working clearance of a radial plain bearing with a modified support profile was developed. The main attention was paid to the effect of a polymer coating with a groove on the distribution of pressure and velocity of the lubricant. To achieve the stated goals, numerical analysis methods were used, which provided the creation of a detailed picture of the distribution of pressure and velocity inside the working zone. Particular emphasis was placed on taking into account the compressibility of the lubricant, which made it possible to significantly improve the accuracy of calculations and increase the reliability of the obtained data. The model proved to be reliable and accurate, which is confirmed by the consistency of the calculated data with experimental measurements. As a result of the modeling, the characteristics of the distribution of pressure and velocity of the lubricant in the system were studied in detail. The study showed that the introduction of a polymer coating with a groove significantly affects the behavior of the lubricant, improving its distribution and reducing potential zones of overheating and wear. Thus, this work is an attempt to make a contribution to the field of radial plain bearing research. The results obtained can be used for further improvement of bearing designs, which will increase their reliability and durability in various industries.
Ritmos del caminar y caminabilidad en las ciudades intermedias, Osorno, Chile
Authors: Martínez-Rodríguez Soledad
Published: January 2025

Intermediate cities, characterized by their shorter distances, could be projected as favorable spaces for adopting active means of mobility such as walking. However, the trend seems to be moving in another direction. The most recent mobility surveys show a decrease in people going for walks and an increase in car use in several intermediate Chilean cities. This phenomenon raises questions about the experiences of those who walk in intermediate cities to understand why these cities could be evaluated as walkable, as walking is no longer a daily mobility option for most people. This article addresses this question based on ethnographic research conducted between 2021 and 2022 in the city of Osorno, in the Los Lagos region, where pedestrian experiences of twenty inhabitants were analyzed. A relevant finding is the frequent disruptions in the rhythms and sense of continuity that participants experience in their trips and their impact on the daily walk. Based on this observation, the proposal is made to incorporate the notion of rhythm into the debate on the walkability of intermediate cities as a valuable element that allows focusing on the experiences that people have while walking and to make progress in the understanding of what makes a city walkable, and what makes its inhabitants want to walk it. In this way, this article contributes to knowledge of pedestrian experiences in non-metropolitan contexts, often ignored in urban walking studies, enriching our understanding of everyday mobility in intermediate cities.

Published: January 2025

Heritage protection in Chile, in the last 20 years, has been strongly influenced by citizen movements, who seek to maintain the identity of their neighborhoods, using the instrument of Typical Zone (ZT) as a protection tool. In principle, a central objective of these actions is to maintain the housing destination as a mechanism to preserve the social fabric. However, in several TZs, the housing facades conceal a diversity of uses. This situation raises doubts regarding the effectiveness of the regulatory tool in relation to the aspirations of the communities. In this sense, the objective of the research was to analyze the changes in the residential character of three neighborhoods after their designation as ZT. The methods used included registration in GIS mapping of land uses for the year 2024 using information from the Internal Revenue Service; these data were complemented with population data from the 2002 and 2017 Censuses. The results point out that the ZT instrument is far from guaranteeing the pursued preservation of the social fabric. These conclusions emphasize the importance of rethinking heritage protection instruments in pericentral areas, so as to aim for a balance between investment attraction and the desired neighborhood identity pursued by communities.

Published: January 2025

Public health has multidisciplinary challenges involving a combination of physical, mental, and social welfare. Two limitations to quantifying indoor pollutants (gases, chemical compounds, and suspended particles) are the high cost and the complexity of available measurement systems. Under this scenario, an experimental approach was used to develop a low-cost system to measure variables that affect human and environmental health. Calibration, validation, and technical adjustment processes were conducted in an extreme-climate location in southern Mexico, following domestic and international standards. The key results showed the feasibility of using low-cost tools to measure pollutants in developing countries. 57% of the data for H2S had a result above 150 ppm, which is considered harmful to human health. On the other hand, developing the measurement system in the studied locality showed the importance of having data to measure environmental pollution levels according to each region's habits and customs. Sensors and open access systems were used as these can directly benefit resource-constrained researchers and the public and private sectors interested in measuring environmental and comfort variables to promote universal access to knowledge.
O ethos dos territórios periféricos do mundo colonial: um pensar a partir dos corpos, do poder e da subjetivação
Authors: Cândido Artur Mamed , Holanda Marianna
Published: January 2025

Partindo de uma abordagem transdisciplinar, este ensaio filosófico versa sobre os processos de subjetivação configurados nos territórios periféricos do mundo colonial. Propõe-se uma leitura compreensiva sobre o legado moral das relações coloniais-escravistas, no que se refere à constituição do ethos ainda vigente nesses territórios. Está pautado nas contribuições de pensadores associados a campos como os da Teoria do Reconhecimento, da Análise do Discurso, da Analítica do Biopoder e dos Estudos Coloniais e Decoloniais, para descrever e conceitualizar formas normativas histórica e politicamente constituídas por meio das quais o pleno reconhecimento da humanidade — enunciada conforme os parâmetros normativos europeus — foi e segue sendo negado aos corpos que habitam as periferias do mundo colonial. Afirma que o perfil ético e valorativo configurado nas periferias do mundo colonial é atualizado, desde o nascimento da Era Moderna, pela instituição de discursos e práticas reiteradas que operam reduzir o status moral de incontáveis corpos, remetendo-os à condição de não pessoas. Assim, lança mão da noção de corpos periféricos para descrever um modo de subjetivação que pode recair sobre incontáveis corporalidades e vivências marcadas pela experiência da violência colonial. Trata-se de imaginar uma categoria de inteligibilidade ético-política que inscreve todos os corpos historicamente marcados pelo domínio moderno-colonial, mesmo que esses já não habitem os territórios periféricos do mundo. De tal modo,a constituição do ethos dos territórios coloniais passa a ser lido enquanto um processo coletivo de produção dos sujeitos sociais acionados por dispositivos caracteristicamente modernos de subjetivação, como os dispositivos da raça, da classe, da capacidade e do gênero, que reproduzem e atualizam incessantemente as configurações de um biopoder colonial.

Este artigo analisará um patente paradoxo: a mesma sociedade que apoia e investe em programas e projetos de inclusão social e que pretende, com muitas dessas ações, discutir e reparar historicamente o lugar atribuído à população negra em nossa sociedade é aquela que, sem titubear, ceifa qualquer possibilidade de ascensão e de representatividade dessa mesma população quando posta à prova, como foi o caso de Luiz Justino. Músico integrante da Orquestra de Cordas da Grota – projeto social de ensino de música erudita localizado na Grota do Surucucu, uma “comunidade” da Zona Sul de Niterói, Rio de Janeiro –, Luiz, jovem e negro, sofreu uma injustificável abordagem no centro de Niterói no dia 2 de setembro de 2020 e imediatamente foi conduzido à delegacia, onde ficou detido até ser transferido no dia seguinte para o presídio de Benfica. Em virtude da grande mobilização dos integrantes da Orquestra junto à mídia e aos movimentos sociais comprometidos com o antirracismo, o m úsico teve sua prisão revogada no dia 6 de setembro de 2020 e foi absolvido do processo no dia 9 de junho de 2021. A etnografia que dá base a este artigo foi realizada por meio da observação direta ao acompanhar os ensaios e apresentações da Orquestra, através de entrevistas com os interlocutores do campo e da análise da repercussão do caso na mídia, uma vez que a prisão do músico e seus desdobramentos foram acompanhados por todo o espectro da mídia, configurando-se como um “caso de repercussão”.

Introdução: A disfagia é uma condição que compromete a capacidade de engolir alimentos e líquidos de forma adequada, podendo resultar em sérios problemas na qualidade de vida, no estado nutricional e na hidratação, além de apresentar riscos de morte. Essa dificuldade de deglutição é comum em pessoas com necessidades especiais, como Síndrome de Down, Paralisia Cerebral e Transtorno do Espectro Autista. Fatores de risco para a disfagia podem ser identificados por qualquer pessoa que receba treinamento adequado de um fonoaudiólogo. Portanto, é crucial que os educadores de pessoas com disfagia sejam treinados para reconhecer sinais e oferecer um manejo alimentar apropriado. Objetivo: Capacitar educadores de indivíduos com disfagia para oferecer cuidados alimentares adequados e prevenir complicações associadas a esta condição. Métodos: As oficinas foram realizadas em uma instituição pública de educação especial destinada a professores de pessoas com disfagia orofaríngea, com foco em estratégias de manejo alimentar. Avaliações foram realizadas antes e após as oficinas para medir o impacto no conhecimento e na satisfação dos participantes. Além disso, foi distribuído material informativo aos educadores. Os dados coletados foram organizados em tabelas no Excel® e analisados por meio de estatística descritiva. Resultados: Todas as participantes (dez) eram mulheres com ensino superior completo. Quando questionadas sobre a compreensão do termo "disfagia", sete (70%) afirmaram compreender um pouco sobre o assunto e referente à habilidade em identificar sinais de disfagia em indivíduos com deficiência, seis (60%) dos participantes se consideraram pouco hábeis. Os resultados revelaram uma melhoria expressiva no entendimento da disfagia após as oficinas, com nove (90%) dos participantes relatando maior segurança no reconhecimento e manejo dos sinais desta condição, sendo que, todas os participantes (100%) reconheceram uma "contribuição significativa" para o aumento de seu conhecimento na área. Conclusão: Este estudo ressalta a importância da capacitação contínua e a necessidade de ampliar iniciativas educativas na área, promovendo um ambiente alimentar seguro e melhorando a qualidade de vida das pessoas com disfagia.

Introdução: A nutrição desempenha um papel crucial no desenvolvimento humano, especialmente nas fases iniciais da vida, onde ocorrem 90% das conexões cerebrais. A Organização Mundial da Saúde (OMS) recomenda o aleitamento materno exclusivo nos primeiros seis meses, seguido por uma introdução gradual de alimentos complementares até os dois anos de idade, visando garantir o desenvolvimento saudável das crianças. No entanto, há uma tendência preocupante de introdução precoce de alimentos complementares, aumentando os riscos de mortalidade, especialmente em áreas com condições precárias de higiene. Objetivo: Validar o conteúdo de um guia de introdução alimentar sob a perspectiva da Fonoaudiologia. Métodos: O desenvolvimento foi realizado em três etapas, sendo o Desenho do Estudo, a Formulação do Material e a Adequação Semântica dos Itens (Validação de Conteúdo). Para a avaliação, participaram fonoaudiólogas (N=5) com experiência nesta temática. Foi utilizado o Índice de Validade de Conteúdo (IVC) para a validação completa do instrumento. Resultados: Para todos os itens avaliados, encontrou-se um valor mínimo de IVC de 0.80 (80%), ou seja, concordância de ao menos quatro dos cinco juízes, seguindo o que é preconizado pela literatura especializada. O instrumento conta com 56 páginas, divididas em tópicos e subtópicos, sendo eles, Atuação Fonoaudiológica; Sucção; Deglutição; Mastigação; Respiração; Introdução; O que é a Introdução Alimentar; Quando e como começar; Alimentação precoce; Cuidado e precauções; 10 passos para uma alimentação saudável; Principais técnicas de Introdução Alimentar; Alimentos que devem ser evitados; Utensílios recomendados; Cortes seguros; Tabela guia do desenvolvimento oral; Qr code direcionando para vídeo de como realizar manobra de desengasgo. Foram utilizadas imagens como apoio visual. Conclusão: Os resultados obtidos demonstram adequação aos critérios científicos de validação de conteúdo, evidenciados pelo IVC superior a 0,80 (80%), indicando que o guia possui fundamentação suficiente para ser utilizado como um recurso na orientação de cuidadores quanto às práticas da introdução alimentar.

OBJECTIVE

To compare the prevalence of diagnosed diabetes among U.S. adults with and without disabilities, overall and by subgroups.

RESEARCH DESIGN AND METHODS

We used data on adults aged ≥18 years from the cross-sectional 2021–2022 National Health Interview Survey to report the prevalence of diagnosed diabetes by functional disability status and for each disability type (hearing, seeing, mobility, cognition, self-care, and communication) separately. With use of the Washington Group Short Set on Functioning indicator, disability was defined according to the categories of milder (reporting some difficulty), moderate (reporting a lot of difficulty), and severe (cannot do at all) by disability type. Crude prevalence and age-standardized prevalence of diabetes were also calculated for adults with any difficulty with any disability by age, sex, race/ethnicity, education, insurance, and poverty-to-income ratio.

RESULTS

Diabetes prevalence increased with number of disability types, was lower among adults with no disability (5.8%) than among those with milder (9.5%) or moderate to more severe (18.3%) disability, and was 4.0–10.3 percentage points higher among those with moderate to more severe disability than among those with milder disability for vision, hearing, mobility, and cognitive disabilities. Diabetes prevalence was similar for adults with milder and moderate to more severe self-care and communication disabilities.

CONCLUSIONS

Prevalence of diabetes was higher among adults with any functional disability than without and increased with increasing number of disability types. Adults with multiple disability types, or those who have difficulty with self-care or communication or other moderate to more severe disabilities, may benefit from diabetes prevention programs.
