Reduction of Colitis in Mice by Chemically Programmed Supramolecular Nanoassemblies of Vitamin–Lipid Conjugates
Authors: Xian Shiyun , Meng Fanchao , Chen Xiaona , Zhu Liqing , Wang Hangxiang
Published: December 2024

Inflammatory bowel disease (IBD) is a relapsing disorder characterized by uncontrolled chronic inflammation of the gastrointestinal tract, posing a significant therapeutic challenge owing to the limited efficacy and undesirable side effects of current therapeutic options. A key pathological hallmark of IBD is the excessive production of reactive oxygen species (ROS). Hence, therapeutic strategies aimed at reducing ROS levels are promising for relieving these inflammatory conditions. Vitamin C—a natural nutrient for the human body—is well known for its potent antioxidant effects. However, the clinical development of vitamin C as a therapeutic drug has been hindered by its poor stability, rapid metabolism, and inadequate tissue accumulation. Herein, we report that the bioavailability of vitamin C can be enhanced by chemically reprogramming it with a small panel of long-chain fatty acids that aid in the aqueous self-assembly of the resulting drug conjugates to create self-deliverable nanoassemblies, enhancing their inflammation disease–oriented delivery and cellular uptake. In mice with dextran sulfate sodium–induced colitis, the optimal vitamin C–lipid nanoassemblies preferentially accumulated in inflamed colonic tissues following systemic administration and substantially ameliorated disease severity. We extended this strategy to incorporate the clinically approved glucocorticoid budesonide into the vitamin C nanosystem, facilitating a synergistic combination. In the chronic colitis model, the combination treatment reduced inflammation without compromising global immunity. Mechanistically, the treatment modulated the intestinal inflammatory microenvironment and altered the immune cell landscape, partly through regulation of the gut microbiome. Given its anticipated negligible side effects, this novel nanoassembly platform leveraging small-molecule lipidation may become a promising therapeutic for treating various inflammatory diseases.
UIEAnything: Zero-Shot Underwater Image Enhancement via Advanced Depth Estimation, White Balance Models, and Improved Sea-thru
Authors: Shao Jinxin , Zhang Haosu , Miao Jianming
Published: December 2024

Underwater image enhancement is fundamental for marine applications yet remains challenging due to complex light–water interactions that degrade image quality through wavelength-dependent absorption and scattering effects. Existing methods often require extensive paired training data and struggle to generalize across diverse underwater conditions. We propose UIEAnything, a novel zero-shot underwater image enhancement framework that integrates automatic white balance preprocessing, physics-guided depth estimation, and an improved restoration algorithm based on underwater light transport theory. Our approach introduces three key innovations: (1) a domain adaptation strategy that bridges the gap between underwater and natural images via physically motivated white balance correction, enabling effective utilization of pre-trained models; (2) an improved Sea-thru algorithm incorporating nonlinear backscatter modeling and adaptive attenuation estimation, accurately capturing the depth-dependent nature of underwater light propagation; and (3) a unified framework that eliminates the need for task-specific training while maintaining physical consistency. Extensive experiments on seven benchmark datasets demonstrate that UIEAnything consistently outperforms state-of-the-art methods, achieving average improvements of 15.3% in PSNR and 12.8% in SSIM. Furthermore, without additional training, our framework demonstrates remarkable generalization capability by successfully addressing other challenging vision tasks involving scattering media, such as image dehazing and sandstorm removal. These results establish UIEAnything as a significant advancement in physics-guided zero-shot learning for image enhancement in complex optical environments.
Technological Change, Capital Deepening and Agricultural TFP Growth: Evidence from Cross-country Comparison of 18 OECD Countries
Authors: Sheng Yu
Published: December 2024

This paper employs deterministic production-frontier analysis (DEA) to evaluate technological progress and its role in agricultural total factor productivity (TFP) growth across OECD countries over the past four decades. Using a newly developed production accounting dataset covering agricultural TFP of 18 OECD countries from 1973 to 2015, we estimate annual production frontier shifts and decompose these changes over three 15-year intervals (1973–1987, 1987–2001, and 2001–2015) into components of technological progress, efficiency gains, and capital deepening. Our findings indicate that technological progress, while partly offsetting changes in input scale, has consistently been the primary driver of agricultural TFP growth among OECD countries. However, since 2000, technological progress in agriculture has decelerated, coinciding with transformative advancements in biological and digital technologies that have accelerated industrial productivity. This shift has redirected agricultural technological progress away from Hicks-neutral improvements towards a labor-augmenting path that benefits capital-intensive economies, contributing to the observed deceleration in agricultural TFP growth across countries.

Authors: Yamaguchi Fabio Seiji Mazzi , Kroes Hector Fugihara , Martins Gabriel Benevides Valiate , Lage Gustavo Estefan , Silva Vitor Matheus , Rudelli Bruno Alves , Marcon Raphael Martus , Gurgel Henrique Melo de Campos
Published: December 2024

Introduction: Telemedicine has emerged as a key tool to overcome socioeconomic disparities, expand healthcare access, and reduce environmental impacts. Its adoption surged during the COVID-19 pandemic, minimizing travel-related barriers and ensuring continuity of care. In Brazil, where regional inequities in healthcare access and pollution heavily affect public health, telemedicine holds significant promise. However, further research is needed to quantify its economic and environmental benefits. Moreover, examining how socioeconomic factors influence patients' preferences for telemedicine is essential. These correlations help identify patterns that may influence telemedicine adoption and provide deeper insights into how socioeconomic factors can affect access to and benefits from remote healthcare services.
Objective: To evaluate the economic and environmental impacts of telemedicine use and the correlation of socioeconomic variables with telemedicine preference in patients with hip pathologies at a tertiary referral center in São Paulo, Brazil.
Methods: A cross-sectional study (January-June 2024) analyzed telemedicine patients, collecting data on preferences, demographics, travel, and costs (transport and food). Avoided distance, time, and pollutant emissions were calculated using Google Maps and emission factors. Correlations were conducted between patients' preference for telemedicine and their socioeconomic data. Statistical analyses used Wilcoxon, chi-square, and logistic regression tests.
Results: 148 patients participated, with 77.7% preferring telemedicine. The mean avoided travel distance was 168.84 km, with a mean time saving of 223.97 minutes. Patients using public transport and private cars saved, respectively, USD 12.62 and USD 28.95. Telemedicine also reduced pollutant emissions, avoiding approximately 7 tons of carbon dioxide. Telemedicine preference was positively associated with higher income (p = 0.0283). Other variables showed no statistically significant associations.
Conclusion: Telemedicine led to significant time and cost savings, as well as a reduction in pollutant emissions. These findings demonstrate telemedicine’s potential to improve access and reduce environmental impacts. Preference for telemedicine was positively associated with higher income, highlighting potential barriers for lower-income populations. Further research is needed to address the lower adherence to virtual consultations among socioeconomically disadvantaged groups.
Lactococcus lactis subsp. cremoris C60 creates a type I regulatory T cell-dominant anti-inflammatory intestinal environment through functional modification of dendritic cells
Authors: Saito Suguru , Kakizaki Nanae , Okuno Alato , Maekawa Toshio , Tsuji Noriko M
Published: December 2024

Lactic acid bacteria (LAB)-mediated probiotics have the capability to modulate intestinal immunity, creating an anti-inflammatory environment. Among the immune-modulatory effects, interleukin (IL)-10-producing CD4+ T cells are often discussed for their anti-inflammatory roles. While regulatory T cells (Tregs) are a well-known subset, type I regulatory T (Tr1) cells, which also produce abundant IL-10, receive less attention in LAB-induced anti-inflammatory effects. Here, we report that Lactococcus lactis subsp. cremoris C60, a probiotic LAB strain, increases IL-10-producing Tr1 cells in the intestinal environment, contributing to resistance against inflammatory conditions such as dextran sodium sulfate (DSS)-induced colitis. Intragastric administration of heat-killed (HK)-C60 significantly increased IL-10+CD4+ T cells in intestinal tissues compared to control treatment. These populations predominantly consisted of Forkhead box protein P3 (Foxp3)-negative cells, indicating that Tr1 cells were primarily expanded by HK-C60 stimulation. Further analysis revealed that IL-10+ Tr1 cells could be classified into two major subpopulations: IL-10 single-positive (SP) and IFN-γ/IL-10 double-positive (DP) cells. An in vitro co-culture system using CD4+ T cells and bone marrow-derived dendritic cells (BMDCs) demonstrated that HK-C60 stimulation modified dendritic cell function, promoting Tr1 cell differentiation. Moreover, pro-inflammatory IFN-γ+CD4+ T (Th1) cells differentiated into IL-10+ Tr1 cells in the presence of HK-C60-stimulated BMDCs, with the effect being particularly pronounced in DP Tr1 cells. HK-C60-administration attenuated inflammation and reduced pro-inflammatory leukocyte infiltration in the colon of DSS-induced colitis mice, accompanied by the expansion of DP Tr1 cells. The suppressive effect of intestinal CD4+ T cells in HK-C60-treated mice was IL-10-dependent, as demonstrated by an in vitro IL-10 neutralizing assay. Thus, C60-based probiotics promote the creation of an anti-inflammatory intestinal environment by increasing IL-10+ Tr1 cells rather than Tregs.

Published: December 2024

The corrosive nature of sub-soil to aggressive attack on buried metallic pipes and concrete, and its competence to withstand overburden stress from civil engineering infrastructures at Otue-Ogume, an oil producing community in Delta State was here assessed with geo-electric and geochemical methods. Nine Vertical Electrical Sounding (VES) was carried out with Mini-Res Resistivity Meter using the Schlumberger array. Soil samples were also collected with hand auger at varying depths of 0-1m, 1-2m and 2-3m at each of the nine VES stations for geochemical analysis. The VES data was processed with IPI2WIN software and delineated six to eight geo-electric layers of lateritic topsoil, clayey sand, sandy clay, Fine-medium grained sand, medium-coarse grained sand, coarse grained sand, sandy clay and clay. The soil resistivity, thickness and depth ranged respectively from 53.04Ωm to 4535Ωm, 0.6m to 79.2m and 0.6m to 134.8m. The geochemical parameters (pH, Cl-, and So42-) were lower than the permissible standards, although the Cl- and So42- concentration could be potentially high with time due to seasonal fluctuations which can trigger the corrosion dynamics of the soil. The subsurface soil layers were characterized as essentially non-corrosive, moderately corrosive and mildly corrosive to concrete and metallic pipes. The subsurface soils were also characterized as highly competent, competent and moderately competent confirming that it can withstand erecting of massive buildings or civil engineering infrastructures to depth of 2m. Treatment of the moderately and mildly corrosive sub-soil layers is strongly advised before crude oil and gas transmission pipes is buried to that depth.
University-Industry Collaborations in European regions: the Effect of Business Cycle on diversification
Authors: Quignon Aurelien
Published: December 2024

This paper explores the effect of the business cycle on university-industry collaborations and technological diversification within 218 European regions from 1990 to 2018. I find that university-industry collaborations increase during economic expansions, with the most pronounced effects observed in the exploitation of technologies already known to the region. In contrast, the exploration of new technologies is also positively associated with economic growth, albeit to a lesser extent. The analysis further shows that the effects of R&D investments on university-industry collaborations vary by sector over phases of the business cycle: private sector R&D expenditures are countercyclical, driving collaboration during recessions, while government R&D spending is procyclical, supporting exploratory activities during economic booms.
Locality of topological dynamics in Chern insulators
Authors: Markov Anton , Golovanova Diana , Yavorsky Alexander , Rubtsov Alexey
Published: December 2024

A system having macroscopic patches in different topological phases has no well-defined global topological invariant. To treat such a case, the quantities labeling different areas of the sample according to their topological state are used, dubbed local topological markers. Here we study their dynamics. We concentrate on two quantities, namely the local Chern marker and the on-site charge induced by an applied magnetic field. The first one provides the correct information about the system’s topological properties, the second can be readily measured in experiment. We demonstrate that the time-dependent local Chern marker is a much more non-local object than the equilibrium one. Surprisingly, large samples driven out of equilibrium lead to a simple description of the local Chern marker’s dynamics by a local continuity equation. Also, we argue that the connection between the local Chern marker and magnetic-field induced charge known in static holds out of equilibrium in some experimentally relevant systems as well. This gives a clear physical description of the marker’s evolution and provides a simple recipe for experimental estimation of the topological marker’s value.

Authors: Galvão Maria Cristiane Barbosa , Ricarte Ivan Luiz Marques
Published: December 2024

Os níveis de evidência em saúde surgem, no século 20, no escopo da medicina baseada em evidências, que buscava e busca integrar a melhor evidência científica disponível à experiência clínica dos profissionais de saúde e à experiência dos pacientes como método para orientar decisões clínicas e melhorar a qualidade da assistência em saúde. Todavia, críticas associadas ao uso dos níveis de evidência em saúde se voltam para a simplificação da abordagem, priorização dos métodos quantitativos, desconsideração do contexto social e cultural da assistência, inadequação de seu emprego para doenças e condições complexas como a saúde mental, doenças raras e cuidados paliativos. Tais críticas e reflexões elucidam os desafios e demandas associadas para a implementação dos níveis de evidência em saúde, que serão objeto de análise neste estudo de caráter teórico. A partir do exposto, as conclusões do presente estudo se voltam para a proposição de possibilidades de implementação dos níveis de evidência na perspectiva do século 21, onde se vislumbra a revisão dos níveis de evidência atuais bem como o desenvolvimento de um novo modelo de revisão sistemática denominado, por ora, revisão sistemática mista, viva e contextualizada.

Authors: Onwuzuligbo Amarachukwu , Uronnachi Emmanuel , Onwuzuligbo Chukwunonso , Umeyor Chukwuebuka , Attama Anthony
Published: December 2024

Background:

Ocimum gratissimum has folklorically been ascribed to possess several
medicinal activities, including antimalarial.

Objective:

This research explored the antimalarial activity in its essential oil and the anti-anaemic
effect of Hibiscus sabdariffa (Hs) in combination.

Methods:

Ocimum gratissimum essential oil (OGE) was extracted through hydro distillation and
analyzed using GC/MS. Hs extract was obtained using cold maceration. Pre-formulation studies
tested their antimalarial and anti-anemic activities using different concentrations of the essential
oil and the Hs extract. Nanoemulsions containing OGE and Hs extract were formulated and characterized
using scanning electron microscopy (SEM), particle size, and polydispersity index (PDI).
Post-formulation anti-anaemic and antimalarial evaluations were conducted.

Results:

The pre-formulation animal studies showed that the group administered 10 ml/kg of 20%
oil had the highest reduction in parasitaemia. Also, 230 mg of Hs gave the highest anti-anaemic activity.
SEM imaging showed homogenous dispersion of the emulsions. Particle sizes and PDI
(size, PDI) were (56.17nm, 0.478), and (44.40 nm, 0.461) for the 10% and 20% nanoemulsions, respectively.
The post-formulation suppressive animal studies gave a maximum parasitemia reduction
of 88.1, and 100%, respectively, for the treatment groups administered 4ml/kg of 20% nanoemulsion
and Artemether-Lumefantrine (AL) 2.3/13.7mg/kg respectively; and a percentage reduction
in parasitemia (curative test), of 74.66 and 99.69% respectively. Hematocrit values and body
weight were increased in the groups treated with the emulsion.

Conclusion:

Emulsions containing O. gratissimum essential oil and H. sabdariffa extract showed
effectiveness in reducing parasitaemia and reversing anaemia in a dose-dependent manner.
Revisits, Readmission, and Mortality From Emergency Department Admissions for Older Adults With Vague Presentations: Longitudinal Observational Study
Authors: Alvarez Avendano Sebastian Alejandro , Cochran Amy , Odeh Couvertier Valerie , Patterson Brian , Shah Manish , Zayas-Caban Gabriel
Published: December 2024

Background

Older adults (65 years and older) often present to the emergency department (ED) with an unclear need for hospitalization, leading to potentially harmful and costly care. This underscores the importance of measuring the trade-off between admission and discharge for these patients in terms of patient outcomes.

Objective

This study aimed to measure the relationship between disposition decisions and 3-day, 9-day, and 30-day revisits, readmission, and mortality, using causal inference methods that adjust for potential measured and unmeasured confounding.

Methods

A longitudinal observational study (n=3591) was conducted using electronic health records from a large tertiary teaching hospital with an ED between January 1, 2014 and September 27, 2018. The sample consisted of older adult patients with 1 of 6 presentations with significant variability in admission: falls, weakness, syncope, urinary tract infection, pneumonia, and cellulitis. The exposure under consideration was the ED disposition decision (admission to the hospital or discharge). Nine outcome variables were considered: ED revisits, hospital readmission, and mortality within 3, 9, and 30 days of being discharged from either the hospital for admitted patients or the ED for discharged patients.

Results

Admission was estimated to significantly decrease the risk of an ED revisit after discharge (30-day window: −6.4%, 95% CI −7.8 to −5.0), while significantly increasing the risk of hospital readmission (30-day window: 5.8%, 95% CI 5.0 to 6.5) and mortality (30-day window: 1.0%, 95% CI 0.4 to 1.6). Admission was found to be especially adverse for patients with weakness and pneumonia, and relatively less adverse for older adult patients with falls and syncope.

Conclusions

Admission may not be the safe option for older adults with gray area presentations, and while revisits and readmissions are commonly used to evaluate the quality of care in the ED, their divergence suggests that caution should be used when interpreting either in isolation.
Assessing ChatGPT’s Clinical Competency and Patient Perceptions in Emergency Medicine: Insights from Clinical Performance Examinations (Preprint)
Authors: Park ChulHyoung , An Min Ho , Hwang Gyubeom , Park Rae Woong , An Juho
Published: December 2024

BACKGROUND

Emergency medicine can benefit from AI due to its unique challenges, such as high patient volume and the need for urgent interventions. However, it remains difficult to assess the applicability of AI systems to real-world emergency medicine practice, which requires not only medical knowledge but also adaptable problem-solving and effective communication skills.

OBJECTIVE

We aimed to evaluate ChatGPT's performance in comparison to human doctors in simulated emergency medicine settings, utilizing the framework of Clinical Performance Examination (CPX).

METHODS

Twenty-eight text-based cases and four image-based cases relevant to emergency medicine were selected. Twelve human doctors were recruited to represent the medical professionals. Both ChatGPT and the human doctors were instructed to manage each case like real clinical settings with simulated patients. After the CPX sessions, the conversation records were evaluated by an emergency medicine professor on history taking, clinical accuracy, and empathy on a 5-point Likert scale. Simulated patients completed a 5-point scale survey including overall comprehensibility, credibility, concern reduction for each case. Additionally, they evaluated whether the doctor they interacted with was similar to a human doctor. The mean scores from ChatGPT were then compared to those of the human doctors.

RESULTS

ChatGPT scored significantly higher than the physicians in both history-taking (mean score 3.91 [SD 0.67] vs. 2.67 [SD 0.78], P < 0.01) and empathy (mean score 4.50 [SD 0.67] vs. 1.75 [SD 0.62], P < 0.01). However, there was no significant difference in clinical accuracy. In the survey conducted with simulated patients, ChatGPT scored higher for concern reduction (mean score 4.33 [SD 0.78] vs. 3.58 [SD 0.90], P = 0.04). For comprehensibility and credibility, ChatGPT showed better performance, but the difference was not significant. In the similarity assessment score, no significant difference was observed (mean score 3.50 [SD 1.78] vs. 3.25 [SD 1.86], P = 0.71).

CONCLUSIONS

ChatGPT’s performance highlights its potential as a valuable adjunct in emergency medicine, demonstrating comparable proficiency in knowledge application, efficiency, and empathetic patient interaction. These results suggest that a collaborative healthcare model, integrating AI with human expertise, could enhance patient care and outcomes.

Seismic Performance Assessment of RC Structure Using Country Specific Codes: A Review
Authors: Pathak Ritika
Published: December 2024

Seismic analysis is critical in ensuring the structural safety and performance of multistorey buildings in earthquakeprone regions. National seismic codes, such as India’s IS 1893:2016, China’s GB 50011-2010 (updated in 2016), and Turkey’s
Turkish Earthquake Code 2018, play a pivotal role in guiding the design and construction of these structures. This review paper
aims to compare the provisions and applications of these three seismic codes with a focus on their treatment of seismic hazards,
structural response parameters, and design methodologies.
Using STAAD.Pro software as a computational tool, the study identifies key differences in base shear calculations, story drift
limits, ductility requirements, and material considerations. While the Indian code emphasizes simplicity and accessibility, it lacks
the detailed performance-based approach of the Chinese code, which integrates advanced probabilistic hazard assessments and
material guidelines. The Turkish code offers a balance between safety and economy, incorporating rigorous site-specific data
and soil-structure interaction considerations. The findings suggest that aligning global seismic standards and adopting advanced
computational tools can significantly enhance the design efficiency and safety of multistorey buildings. This review contributes
to the broader knowledge base of seismic engineering and provides insights for improving code practices in regions with diverse
seismic risks.
Response of Exterior Beam-Column Joint with Rectangular Spiral Reinforcement under Cyclic Loading
Authors: Sonawane Yogesh Narayan
Published: December 2024

This study presents an experimental evaluation of the performance of exterior beam-column joints reinforced with
rectangular spiral reinforcement. Beam-column joints are critical regions in reinforced concrete structures, and their behavior
significantly influences the overall seismic performance of buildings. Traditional reinforcement techniques for these joints often
struggle with issues such as inadequate confinement and potential failure under cyclic loading. In an effort to improve the
structural integrity and enhance the seismic resistance of these joints, the use of rectangular spiral reinforcement was explored
as an alternative. The experimental program involved testing of beam-column joint specimens under cyclic loading conditions to
assess their strength, crack patterns hysteresis behaviour. The specimen was designed with varying configurations of rectangular
spiral reinforcement in the joint region, and their performance was compared to traditional reinforcement methods. Key
parameters, including crack patterns, load-deflection behavior, and ultimate failure modes, were analysed. The results indicated
that rectangular spiral reinforcement provided better confinement, resulting in improved strength and enhanced seismic
performance under cyclic loading. The study concludes that rectangular spiral reinforcement can be an effective solution for
improving the resilience of exterior beam-column joints in earthquake-prone regions. This research contributes to the
development of more reliable reinforcement strategies for structural joints, promoting safer and more durable building designs.

This qualitative study explores the potential of Augmented Reality (AR) in enhancing the understanding of biological concepts through the lens of constructivism theory. The research aims to investigate how AR technology can be leveraged to create immersive and interactive learning experiences in biology education. By examining the perspectives of educators, students, and AR developers, this study seeks to provide insights into the effectiveness of AR in constructing knowledge and promoting deeper comprehension of complex biological processes. This research uses a qualitative approach with a literature study method and descriptive analysis to explore the understanding of biological concepts through Augmented Reality (AR) from the perspective of constructivism theory.Augmented Reality (AR) is revolutionizing educational paradigms by creating immersive learning environments that blend physical and digital elements, This technology supports the constructivist learning theory by allowing students to actively construct knowledge through direct interaction with virtual biological models, fostering deeper comprehension of complex biological systems and processes.While AR presents significant educational potential, its implementation in biology education faces several challenges that require careful consideration and strategic solutions. AR can help students understand complex concepts in a more exciting and fun way. In the context of constructivism theory, AR supports active, collaborative, and experience-based learning, which is very important in biology education.

This article focus on Islamic banking syndicated financing in the context of funding strategic projects in Aceh Province after the enactment of Qanun Number 11 of 2018. The research methodology used is normative legal study, which includes analysis of norms, principles of Islamic banking, and opinions of Islamic economic law experts. The approaches employed are the legislative approach. The object of this research is focused on the role of Islamic banks and the mechanisms carried out by Islamic banking in syndicated financing after the establishment of Qanun Number 11 of 2018 concerning Islamic Financial Institutions. The results of this study indicate that in the context of funding strategic projects, the infrastructure development of Aceh Province. That Islamic banking syndicated financing has an important role on the basis of financing needs on a large scale. It is hoped that the syndicated financing will be the right solution by referring to several provisions that contain sharia principles in the sharia banking syndicated financing process. The enactment of Qanun Number 11 of 2018 concerning Islamic Financial Institutions, became the legal basis for the implementation of syndicated financing. In addition, it also refers to the fatwa issued by DSN-MUI Number 91/DSN-MUI/IV/2014 concerning Syndicated Financing (Al-Tamwil Al-Mashrifi Al-Mujamma'), and based on OJK Circular Letter No. 36/SEOJK.03/ 2015 concerning Products and Activities of Islamic Commercial Banks and Sharia Business Units. So the implementation of syndicated financing at Islamic banks in Indonesia is in principle in line with the existing provisions in Sharia, but still must continue to be supervised by the Sharia Supervisory Board/DPS in this case the context is the Aceh Sharia Council/DSA so that there are no violations in its implementation.
Nude aesthetics of the disabled persons: a political and anti-normative political analysis
Authors: Abreu Passos Fábio
Published: December 2024

In every society, the body has always been in the clutches of powers that impose limits and prohibitions on it. In contemporary times, however, the dispositive for monitoring the body have expanded, aiming to disassemble and reassemble it based on established norms. From this machinery emerges a binary understanding of human corporeality: on one side, the healthy, beautiful, normal, and the efficient; on the other, the sick, ugly, abnormal, and disabled. Given this scenario, it is important that we create an environment in which it is possible to form free citizens who are artists of themselves, who turn their lives into works of. This article reflects on the antinormative nudity of people with disabilities, while trying to answer the following questions: What does it mean to have an abnormal body? Does the disabled person have a body that carries an aesthetic? The answer to these questions will be brought through political philosophy reflections and with my artistic works. I am, hoping to bring the invisible effects that the machinery of governmentality has on the bodies of people with disabilities to the surface of public dialogue while, at the same time, creating a locus that enables the visibility of these same bodies.
The Gender Issue in the African Union Peace and Security Council
Authors: Losekann Raquel Losekann , Santos Luis Haroldo Pereira
Published: December 2024

The purpose of this paper is to analyse the initiatives related to the Women, Peace and Security Agenda of the Peace and Security Council of the African Union since 2000, when United Nations Security Council Resolution 1325 was launched. It seeks to answer the following question: to what extent has the PSC contributed to the implementation of the UNSC's “Women, Peace and Security” Agenda on the African continent? It considers the hypothesis that the PSC works on this issue based on four pillars from a holistic and integrated perspective, even if it has not achieved the full realisation of these measures. The research methodology consists of document analysis and is based on a qualitative approach, supported by a literature review. The main documents analysed were resolutions, meeting minutes, official PSC reports, and the Continental Framework Results indicators. The main results were that the PSC's conception of gender actions, despite following a “UN” model, is broader and more integrated. Although the Women, Peace and Security Agenda has been introduced at the normative level, there are still a series of implementation challenges.

Motion capture: estratégia imersiva para o corpo dançante
Authors: Silva Aires Daniel , Fagundes Dantas Mônica
Published: December 2024

Este artigo busca explicitar algumas características das tecnologias de motion capture ou captura de movimentos 3D em situação de Dança, desde uma perspectiva de documentação e da funcionalidade dos sistemas até uma noção de imersão para aquele que doa seus movimentos e produz arquivos de si, seja ele o corpo dançante. Deste horizonte, explana-se sobre o assunto a partir dos experimentos e criações que temos realizado no Sul do Brasil junto ao Programa de Pós-graduação em Artes Cênicas, [nome da instituição removida para avaliação], e que contextualizam a experiência imersiva para o corpo dançante. Com o objetivo de aprofundar as relações entre o corpo dançante e a experiência corporificada em ambientes imersivos tecnológicos e de alargar o entendimento tecnológico em Dança, utiliza-se de entrevista semiestruturada com um artista-pesquisador-participante dos projetos que temos desenvolvido. O texto se conclui na proposição do motion capture como estratégia de expansão sensório-espacial e imersiva, em uma proposição que escapa a ideia de simulação.
