Published: October 2024

The Spaceborne Global Lightning Location Network (SGLLN) serves the purpose of identifying transient lightning events occurring beneath the ionosphere, playing a significant role in detecting and warning of disaster weather events. To ensure the effective functioning of the wideband electromagnetic pulse detector, which is a crucial component of the SGLLN, it must be tested and verified with specific signals. However, the inherent randomness and unpredictability of lightning occurrences pose challenges to this requirement. Consequently, a high-power electromagnetic pulse radiation system with a 20 m aperture reflector is designed. This system is capable of emitting nanosecond electromagnetic pulse signals under pre-set spatial and temporal conditions, providing a controlled environment for assessing the detection capabilities of SGLLN. In the design phase, an exponentially TEM feed antenna has been designed firstly based on the principle of high-gain radiation. The feed antenna adopts a pulser-integrated design to mitigate insulation risks, and it is equipped with an asymmetric protective loading to reduce reflected energy by 85.7%. Moreover, an innovative assessment method for gain loss, based on the principle of Love’s equivalence, is proposed to quantify the impact of feed antenna on the radiation field. During the experimental phase, a specialized E-field sensor is used in the far-field experiment at a distance of 400 m. The measurements indicate that at this distance, the signal has a peak field strength of 2.2 kV/m, a rise time of 1.9 ns, and a pulse half-width of 2.5 ns. Additionally, the beamwidth in the time domain is less than 10°. At an altitude of 500 km, the spaceborne detector records a signal with a peak field strength of approximately 10 mV/m. Particularly, this signal transformed into a nonlinear frequency-modulated signal in the microsecond range across its frequency spectrum, which is consistent with the law of radio wave propagation in the ionosphere. This study offers a stable and robust radiation source for verifying spaceborne detectors and establishes an empirical foundation for investigating the impact of the ionosphere on signal propagation characteristics.

Published: October 2024

Robotic grasping is a common operation scenario in industry and agriculture, in which the force sensing function is a significant factor to achieve reliable grasping. Existing force sensing methods of flexible grippers require intelligent materials or force sensors embedded in the flexible gripper, which causes such problems of higher manufacturing requirements and contact surface properties changing. In this paper, a novel rope-driven force sensing flexible gripper is designed based on the fin-shaped gripper structure, which can realize the grasping sensing functions of contact nodes and contact forces without the need for force sensors. Firstly, the rope-driven force sensing flexible gripper is designed, including the driving unit, the transmission part, the gripper unit, and the force sensing unit. The force sensing unit and the gripper unit are connected by rope, and the prototype of the rope-driven force sensing flexible gripper is completed. Secondly, a force sensing algorithm and control system based on finite element method and grasping geometric relationship are designed to realize the rope-driven force sensing flexible gripper grasping control and sensor data acquisition and processing. Finally, the experimental system of the rope-driven force sensing flexible gripper is built, and the grasping experimental tests of objects with different diameters and different contact nodes are carried out to verify the force sensing function of the rope-driven force sensing flexible gripper. The force sensing flexible gripper designed in this paper can provide a new idea for the design and force sensing method of intelligent robotic grasping system in robotic teaching, scientific research, and industrial applications.

Published: October 2024

Minimally invasive interventional surgery is commonly used for diagnosing and treating breast cancer, but the high fluidity and deformability of breast tissue reduce intervention accuracy. This study proposes a bionic breast interventional robot that mimics the scorpion’s predation process, actively manipulating tissue deformation to control target displacement and enhance accuracy. The robot’s structure is designed using a modular method, and its kinematics and workspace are analyzed and solved. To address the nonlinear breast tissue deformation problem, a hierarchical tissue method is proposed to simplify the three-dimensional problem into a two-dimensional one. A two-dimensional tissue deformation solver is established based on the minimum energy method for quick resolution. The problem is treated as quasi-static, deriving the displacement relationship between external manipulation points and internal tissue targets. The method of active manipulation of tissue deformation is simulated using MATLAB (2019-b) software to verify the feasibility of the method. Results show maximum errors of 1.7 mm for prostheses and 2.5 mm for in vitro tissues in the X and Y directions. This method improves intervention accuracy in breast surgery and offers a new solution for breast cancer diagnosis and treatment.

Published: October 2024

Visually Impaired Persons (VIPs) have difficulty in recognizing vehicles used for navigation. Additionally, they may not be able to identify the bus to their desired destination. However, the bus bay in which the designated bus stops has not been analyzed in the existing literature. Thus, a guidance system for VIPs that identifies the correct bus for transportation is presented in this paper. Initially, speech data indicating the VIP’s destination are pre-processed and converted to text. Next, utilizing the Arctan Gradient-activated Recurrent Neural Network (ArcGRNN) model, the number of bays at the location is detected with the help of a Global Positioning System (GPS), input text, and bay location details. Then, the optimal bay is chosen from the detected bays by utilizing the Experienced Perturbed Bacteria Foraging Triangular Optimization Algorithm (EPBFTOA), and an image of the selected bay is captured and pre-processed. Next, the bus is identified utilizing a You Only Look Once (YOLO) series model. Utilizing the Sub-pixel Shuffling Convoluted Encoder–ArcGRNN Decoder (SSCEAD) framework, the text is detected and segmented for the buses identified in the image. From the segmented output, the text is extracted, based on the destination and route of the bus. Finally, regarding the similarity value with respect to the VIP’s destination, a decision is made utilizing the Multi-characteristic Non-linear S-Curve-Fuzzy Rule (MNC-FR). This decision informs the bus conductor about the VIP, such that the bus can be stopped appropriately to pick them up. During testing, the proposed system selected the optimal bay in 247,891 ms, which led to deciding the bus stop for the VIP with a fuzzification time of 34,197 ms. Thus, the proposed model exhibits superior performance over those utilized in prevailing works.
A Survey of Advanced Border Gateway Protocol Attack Detection Techniques
Authors: Scott Ben A. , Johnstone Michael N. , Szewczyk Patryk
Published: October 2024

The Internet’s default inter-domain routing system, the Border Gateway Protocol (BGP), remains insecure. Detection techniques are dominated by approaches that involve large numbers of features, parameters, domain-specific tuning, and training, often contributing to an unacceptable computational cost. Efforts to detect anomalous activity in the BGP have been almost exclusively focused on single observable monitoring points and Autonomous Systems (ASs). BGP attacks can exploit and evade these limitations. In this paper, we review and evaluate categories of BGP attacks based on their complexity. Previously identified next-generation BGP detection techniques remain incapable of detecting advanced attacks that exploit single observable detection approaches and those designed to evade public routing monitor infrastructures. Advanced BGP attack detection requires lightweight, rapid capabilities with the capacity to quantify group-level multi-viewpoint interactions, dynamics, and information. We term this approach advanced BGP anomaly detection. This survey evaluates 178 anomaly detection techniques and identifies which are candidates for advanced attack anomaly detection. Preliminary findings from an exploratory investigation of advanced BGP attack candidates are also reported.

Published: October 2024

In this paper, we introduce a security approach for on-device learning Edge AIs designed to detect abnormal conditions in factory machines. Since Edge AIs are easily accessible by an attacker physically, there are security risks due to physical attacks. In particular, there is a concern that the attacker may tamper with the training data of the on-device learning Edge AIs to degrade the task accuracy. Few risk assessments have been reported. It is important to understand these security risks before considering countermeasures. In this paper, we demonstrate a data poisoning attack against an on-device learning Edge AI. Our attack target is an on-device learning anomaly detection system. The system adopts MEMS accelerometers to measure the vibration of factory machines and detect anomalies. The anomaly detector also adopts a concept drift detection algorithm and multiple models to accommodate multiple normal patterns. For the attack, we used a method in which measurements are tampered with by exposing the MEMS accelerometer to acoustic waves of a specific frequency. The acceleration data falsified by this method were trained on an anomaly detector, and the result was that the abnormal state could not be detected.

Published: October 2024

Osteoarthritis (OA) is a global problem. There are few reports in the literature regarding the temporal and spatial parameters of gait in people with OA. The aim of this study was to determine spatiotemporal parameters for the pelvis and lower limbs during walking in women with OA and to compare these parameters with healthy people. For this purpose, a 6 min walking test (6MWT) was carried out. OA subjects had worse outcomes compared to the control group (p < 0.05). Data were collected using IMU sensors integrated into the MoKA system and mounted on indicator points on the body. Limited mobility of the pelvis in the frontal plane was observed in the study group, which influenced walking strategy. For the comparison with the control group at each minute, p < 0.05. IMU sensors attached to the body and integrated in one application provide extensive research and diagnostic capabilities.
Approximate Observation Weighted ℓ2/3 SAR Imaging under Compressed Sensing
Authors: Li Guangtao , Xin Dongjin , Li Weixin , Yang Lei , Wang Dong , Zhou Yongkang
Published: October 2024

Compressed Sensing SAR Imaging is based on an accurate observation matrix. As the observed scene enlarges, the resource consumption of the method increases exponentially. In this paper, we propose a weighted ℓ2/3-norm regularization SAR imaging method based on approximate observation. Initially, to address the issues brought by the precise observation model, we employ an approximate observation operator based on the Chirp Scaling Algorithm as a substitute. Existing approximate observation models typically utilize ℓq(q = 1, 1/2)-norm regularization for sparse constraints in imaging. However, these models are not sufficiently effective in terms of sparsity and imaging detail. Finally, to overcome the aforementioned issues, we apply ℓ2/3 regularization, which aligns with the natural image gradient distribution, and further constrain it using a weighted matrix. This method enhances the sparsity of the algorithm and balances the detail insufficiency caused by the penalty term. Experimental results demonstrate the excellent performance of the proposed method.
Photoelectric H2S Sensing Based on Electrospun Hollow CuO-SnO2 Nanotubes at Room Temperature
Authors: Zou Cheng , Peng Cheng , She Xiaopeng , Wang Mengqing , Peng Bo , Zhou Yong
Published: October 2024

Pure tin oxide (SnO2) as a typical conductometric hydrogen sulfide (H2S) gas-sensing material always suffers from limited sensitivity, elevated operation temperature, and poor selectivity. To overcome these hindrances, in this work, hollow CuO-SnO2 nanotubes were successfully electrospun for room-temperature (25 °C) trace H2S detection under blue light activation. Among all SnO2-based candidates, a pure SnO2 sensor showed no signal, even toward 10 ppm, while the 1% CuO-SnO2 sensor achieved a limit of detection (LoD) value of 2.5 ppm, a large response of 4.7, and a short response/recovery time of 21/61 s toward 10 ppm H2S, as well as nice repeatability, long-term stability, and selectivity. This excellent performance could be ascribed to the one-dimensional (1D) hollow nanostructure, abundant p-n heterojunctions, and the photoelectric effect of the CuO-SnO2 nanotubes. The proposed design strategies cater to the demanding requirements of high sensitivity and low power consumption in future application scenarios such as Internet of Things and smart optoelectronic systems.
Experimental Comparison of Two Main Paradigms for Day-Ahead Average Carbon Intensity Forecasting in Power Grids: A Case Study in Australia
Authors: Zhang Bowen , Tian Hongda , Berry Adam , Huang Hao , Roussac A. Craig
Published: October 2024

Accurate carbon intensity forecasts enable consumers to adjust their electricity use, reducing it during high fossil-fuel generation and increasing it when renewables dominate. Existing methods for carbon intensity forecasting can be categorized into a source-disaggregated approach (SDA), focused on delivering individual generation forecasts for each potential source (e.g., wind, brown-coal, etc.), and a source-aggregated approach (SAA), attempting to produce a single carbon intensity forecast for the entire system. This research aims to conduct a thorough comparison between SDA and SAA for carbon intensity forecasting, investigating the factors that contribute to variations in performance across two distinct real-world generation scenarios. By employing contemporary machine learning time-series forecasting models, and analyzing data from representative locations with varying fuel mixes and renewable penetration levels, this study provides insights into the key factors that differentiate the performance of each approach in a real-world setting. The results indicate the SAA proves to be more advantageous in scenarios involving increased renewable energy generation, with greater proportions and instances when renewable energy generation faces curtailment or atypical/peaking generation is brought online. While the SDA offers better model interpretability and outperforms in scenarios with increased niche energy generation types, in our experiments, it struggles to produce accurate forecasts when renewable outputs approach zero.
The Impact of Air Pollution Risk on the Sustainability of Crop Insurance Losses
Authors: Wang Bingxia , Haron Mohd Azmi , Siri Zailan
Published: October 2024

Climate change poses significant risks to natural and economic environments, particularly through its interaction with air pollution. As agriculture is vital for national production, and crop insurance supports social security, it is crucial to examine how air pollution affects crop insurance. Here, we quantify the impact of air quality on crop insurance claims from an actuarial perspective and evaluate the implications for the industry. Utilizing claims data from the U.S., we explore the potential of particulate matter (PM2.5) as a predictor of insurance claims, building on literature that highlights its economic damage to crops. Through the application of a generalized additive model (GAM) and extreme gradient boosting, we found that PM2.5 is indeed a factor influencing crop insurance indemnity in both models, with the GAM demonstrating superior predictive performance. Furthermore, we employed Bai and Perron breakpoint analysis to elucidate the relationship between PM2.5 levels and crop insurance claims over time, alongside two-way fixed effects models to investigate its correlation with various crop types. Our findings highlight the need for crop insurance managers to integrate air quality considerations into their risk processes to ensure sustainability of the industry and pricing strategy in the face of evolving environmental challenges.

Published: October 2024

Citrus fruits are among the most produced and traded agricultural products worldwide, with significant economic and social importance. Despite their importance in the European Union, Middle East, and Africa, the existing literature is limited. Several studies have reviewed different aspects of general agri-food supply chains, but a product-based literature review on citrus supply chains has not been conducted. This paper provides a comprehensive review of the citrus supply chain in these regions, identifying the key research topics, methodologies, and supply chain echelons addressed in the literature. The study employed a systematic review, real-world case studies, and supply chain stakeholders’ interviews. This multi-faceted approach allows researchers to highlight research gaps, map a complete citrus supply chain, and provide a detailed material flow and sustainability-oriented overview of potential inputs and outputs at different stages. By incorporating real-world case studies and stakeholder interviews, this paper offers a nuanced and practical perspective on the operational and sustainability challenges unique to the citrus supply chain. This study serves as a guide for future research and enables practitioners to pinpoint areas and strategies for operational improvement across the supply chain.

Published: October 2024

The global transition towards a carbon-neutral economy highlights the potential of biomass as a renewable fuel source. However, the sustainability of biomass energy systems is challenged by its complex fouling behaviours during combustion. This study investigates the impact of air staging on mitigating fouling in biomass combustion. By optimising the secondary-to-total air flowrate ratio (Qs/Qt) and the positioning of secondary air, this research investigates the impact of operational and design parameters on fouling deposits in biomass combustion. A fixed-bed combustor was used for the experiments, with hardwood pellets as fuel. This study employed TGA and SEM to analyse the fouling deposit samples’ chemical composition and morphology. First, visible inspection established that the inclination of fouling matter to accumulate on cooled deposition pipes is indeed sensitive to Qs/Qt. The results show that lower Qs/Qt ratios (<0.50) lead to heavier, stickier fouling. Peak temperatures in the fuel bed increase with higher Qs/Qt, enhancing the combustion efficiency and affecting the fouling characteristics. SEM analysis further shows that higher Qs/Qt ratios produce finer, more dispersed fouling particles, whereas lower ratios result in larger, more cohesive particles. These findings provide actionable insights for enhancing the sustainability of biomass energy systems and minimising their environmental impact.

Published: October 2024

The architecture, engineering, and construction (AEC) industry faces ongoing challenges in enhancing safety performance. Despite the availability of advanced technologies for enhancing safety, there is limited understanding of the inter-relationships among safety factors and advanced technologies for enhancing safety performance. This study aims to investigate the inter-relationships among factors affecting safety performance and advanced technologies. A questionnaire survey was disseminated to construction professionals to assess the criticality of factors and strategies. The data were analyzed using descriptive statistics, correlation analysis, and exploratory factor analysis (EFA). The findings indicate that 16 factors and eight advanced technologies are critical for enhancing safety. The EFA grouped 11 critical factors into four underlying groupings: safety planning and hazard prevention, workplace environment and supervision, employee safety support, and medical readiness and site protection. Moreover, the EFA grouped the eight critical advanced technologies into two underlying groupings: advanced digital technologies and personal and site monitoring technologies. The correlation analysis demonstrates measurable but weak associations between the factors and advanced technologies, indicating the need for future research to explore additional variables that may impact these relationships. The findings help construction professionals prioritize resources to address the specific groupings of critical factors and advanced technologies.

Authors: Alzamil Waleed
Published: October 2024

Despite efforts to solve the housing crisis in Saudi Arabia, there are still many challenges related to providing affordable housing due to the high cost of production. Cooperative housing is an approach that achieves the principle of affordable housing through collective effort and effective management. However, activating sustainable cooperative housing production is a process that involves reforming the entire housing system, including policies, subsidies, management, and financing. This study aims to develop a conceptual framework to activate cooperative housing production in Saudi Arabia so as to achieve affordable housing. The research methodology relies on a theoretical approach to identify the relationship between cooperative housing and urban systems so as to determine the factors of cooperative production, including housing policies, management, subsidies, and financing, within a participatory framework. This study focuses on monitoring the situation of cooperative housing and local housing challenges using theoretical concepts, indicators, and international experiences. This study proposes a comprehensive framework for the production of cooperative housing that effectively affects the Saudi housing market and is compatible with the needs of people with low incomes.

Published: October 2024

Currently, the production of waste in the food industry is increasing, which is a serious problem. However, most of these residues, especially those derived from fruits and vegetables, have great unknown properties that are not used. The main objective of this article is the analysis and characterization of the waste from quince after its processing to observe its properties and its potential use in different industries as a functional ingredient, thus favoring the circular economy and sustainability. Quince by-product nutritional parameters such as proteins, fibers, sugars, vitamins, and minerals were analyzed. Also, the antioxidant capacity was measured by various methods: 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity (DPPH), antioxidant capacity in Trolox equivalent antioxidant capacity (TEAC/ABTS), and total polyphenol content (TPC). Finally, the antimicrobial capacity against different postharvest-pathogenic fungi was measured in direct sample and extract. The nutritional results showed a nutritional profile rich in soluble and insoluble fiber, potassium, calcium, and magnesium, and low in fat. The antioxidant results from the extract showed significant levels of phenols and higher antioxidant capacity from the extracted sample. No positive results were found in the antimicrobial capacity study. Quince by-products could be a potential ingredient in the industry due to their nutritional composition and antioxidant content.

Climate and land use change pressures are critical to food production in Social-Ecological Systems (SESs). This study assessed farmers’ perceptions of the pressures of climate and land use changes alongside their impacts on food production in Mhahakanumulla Village Tank Cascade System (MVTCS), a SES maintained by traditional agricultural land use systems in the dry zone of Sri Lanka. This study used both rating and ranking scale questions to quantify farmers’ perceptions. The tobit regression model was employed to evaluate how farmer perception was influenced by socio-economic factors. The results showed that most of the farmers had experienced that the climate of the MVTCS area had changed over time, and they perceived variability of rainfall patterns as the most prominent and influential climate change. The increased cost of production, wildlife damage, and land degradation were ranked by the farmers as the most impactful factors of food production due to climate change. The farmers rated deforestation and land clearing as the most influential and impactful changes in land use, while wildlife damage and land degradation ranked as the highest impacts on food production due to land use changes. Among the socio-economic determinants, training and income/profit positively influenced farmer perceptions of the severity of both climate and land use change. The level of farmer’s adaptation to climate change had a negative association with their perception of the severity of climate change. Household size negatively influenced the perceptions of the severity of climate change while positively influencing perceptions of land use change impacts. Among the spatial determinants, farm size and downstream locations of MVTCS positively influenced perceptions of the severity of both climate and land use change. Thus, the effectiveness of adaptation strategies towards climate and land use change pressures depends on how well they are understood by the farmers. The study findings provide helpful insights for formulating localized land use policies and climate change adaptation strategies in these globally important landscapes with a combination of both top-down and bottom-up approaches.

Published: October 2024

Resources and environment are essential elements of social and economic development. Whether the current resources and environment can sufficiently support economic and social development is an important scientific issue. Existing studies have not reached a consensus on the definition, assessment, and forewarning methods of resource and environmental carrying capacity (RECC). Therefore, this study puts forward a ternary theoretical system of RECC from the perspective of pressure, support, and adjustment, constructs a novel evaluation indices system of RECC, introduces a ternary evaluation model, and proposes a hierarchical forewarning method of RECC with a threshold of 1. Furthermore, an empirical demonstration of 31 provinces in China is presented. The results show that: (1) the average RECC index of 31 areas revealed a downward trend from 2012 to 2021, indicating the gradually improving RECC; (2) the RECC indices of central areas were always high, which manifests the poor RECC; (3) the number of provinces with RECC at Alert Level III decreased from 18 to 7, and the number of provinces at Non-Alert Level increased from 6 to 8.

Background: The effect of initial immunosuppressive therapy on the kinetics of the SARS-CoV-2 vaccine-induced humoral response is unknown. Here, we compared the kinetics of SARS-CoV-2 vaccine-induced humoral response in chronic kidney disease patients undergoing kidney transplantation (KTRs) and compared to patients remaining on dialysis during the Omicron circulation. Methods: This prospective, non-randomized, real-world study included 113 KTRs and 108 patients on dialysis. Those with previous COVID-19 or negative IgG at screening were excluded. Blood samples were collected to assess SARS-CoV-2 IgG titers and neutralizing antibodies at months (M) 1, 3, 6, and 12. Results: Seroreversion occurred in one KTR and in three patients on dialysis. KTRs had lower IgG titers over time (M1: 10,809.3 ± 12,621.7 vs. 15,267.8 ± 16,096.2 AU/mL; M3: 12,215.5 ± 12,885.8 vs. 15,016.2 ± 15,346.1 AU/mL; M6: 12,540.4 ± 13,010.7 vs. 18,503.5 ± 14,581.0 AU/mL; p = 0.005), but neutralizing antibodies were similar (M1: 94.0 vs. 90.3%; M3: 92.9 vs. 90.5%; M6: 99.0 vs. 95.5%; M12: 98.9 vs. 97.5%; p = 0.812). During follow-up, KTRs received more vaccines (141 vs. 73; p < 0.001) and contracted more COVID-19 (32.7% vs. 14.8%; p = 0.002). Conclusions: Compared to patients on dialysis, KTRs had lower SARS-CoV-2 IgG titers and similar rates of seroreversion and neutralizing antibodies over time. Although KTRs received more boosters, they had a higher incidence of COVID-19.

Following the issuance of Constitutional Court Decision Number 46/PUU-VIII/2010 concerning amendments and additions to Article 43 of Law Number 1 of 1974 concerning Marriage, significant changes have been made to family law in Indonesia. These changes pertain specifically to the status of children born out of wedlock who may now be legitimized. Constitutional Court Decision Number 46/PUU-VIII/2010 declares and confirms that children born out of wedlock can now have civil relationships with their biological fathers akin to legitimate children, not only with their mothers and maternal families. Previously, children born out of wedlock only had civil relationships with their mothers and maternal families. To establish a civil relationship with a child born out of wedlock, the biological father must acknowledge paternity. In practice, the biological father can acknowledge paternity by petitioning the District Court, and the custody rights over the child born out of wedlock lie with the biological father. This can be substantiated through scientific and technological evidence or other legal evidence. The research conducted is of a normative legal nature, and the data analysis employs a qualitative descriptive method

Published: October 2024

En el presente artículo realizamos una primera aproximación al análisis de la interpretación simultánea en Lengua de Señas Argentina (LSA) de términos de economía en el discurso político. Nos proponemos observar el comportamiento de los términos interpretados en discurso político sobre la base del encuadre metodológico de la Teoría  Comunicativa  de  la Terminología (TCT) desarrollada por María Teresa Cabré (2005).
El análisis parte del proceso de reflexión activa del equipo de trabajo sobre los desafíos afrontados durante la interpretación en LSA de los discursos políticos en español y la toma de decisiones adoptadas para su resolución, en tanto que los autores formamos parte del mismo. Abordamos un corpus compuesto por 5 videos de discursos producidos por Cristina Fernández de Kirchner en Cadena Nacional de la misma temática entre los años 2013 y 2015 con interpretación en LSA y las transcripciones correspondientes. La cuestión de la deuda externa es un tema recurrente vuelva a estar en la agenda de discusión política y se ha convertido en los últimos años en una protagonista central del discurso político (Suarez y Corvallán, 2022). 
Los resultados evidencian la necesidad de estudios en las áreas de terminología en LSA, especialmente en lo que se refiere al estudio de los signos-términos dentro de diferentes áreas de conocimiento.

Uma revisão integrativa sobre linfogranuloma venéreo (LGV) é essencial para sintetizar e analisar criticamente as evidências científicas disponíveis, proporcionando uma visão abrangente e atualizada sobre a epidemiologia, fisiopatologia, diagnóstico, tratamento e prevenção dessa doença sexualmente transmissível emergente. O objetivo deste estudo é consolidar e analisar criticamente essas evidências para orientar políticas de saúde e práticas clínicas mais eficazes, direcionadas às necessidades da população brasileira. A revisão, realizada entre julho e agosto de 2024, abrangeu 22 estudos, 3 capítulos de livros e 12 documentos de órgãos de saúde, focando em produções desde 2002. Os resultados destacaram a crescente incidência de LGV em homens e mulheres sexualmente ativos no Brasil, com predomínio de casos na faixa etária de 15 a 40 anos. Observou-se um aumento significativo de surtos em países desenvolvidos, particularmente em homens brancos homossexuais, com forte associação ao HIV. A coinfecção de LGV com HIV foi significativa, especialmente em populações de alto risco. A revisão enfatiza a relevância do diagnóstico precoce, utilizando técnicas laboratoriais sensíveis como os testes de amplificação de ácido nucleico (TAAN) e destaca que o tratamento adequado é crucial para conter a disseminação da infecção. Medidas de prevenção, incluindo o tratamento de parceiros sexuais e uma abordagem multidisciplinar, são essenciais para o manejo eficaz do LGV. Assim, a vigilância epidemiológica contínua e a implementação de estratégias de saúde pública são fundamentais para reduzir a morbidade associada a essa doença e melhorar a saúde da população brasileira, especialmente entre os grupos mais vulneráveis.

Published: October 2024

O bem-estar social e a segurança pública são desafios que necessitam de acompanhamento constante, com práticas de médio e longo prazo, assim como exige que diversos profissionais estejam atuando de acordo com padrões estabelecidos pelo Estado e que venham a atender as demandas da população. Estas discussões envolvem questões sociais, mas também aspectos técnicos e operacionais, especialmente dentro das forças de segurança. Com isso, é possível a inserção de uma discussão polêmica dentro do estudo: o uso das bodycams pelas forças militares de segurança. Com isso, o estudo tem como objetivo geral analisar os principais desafios da inserção destas ferramentas tecnológicas no trabalho cotidiano dos policiais. Como objetivos específicos: analisar os argumentos que sustentam o uso destas ferramentas; verificar quais fatores impõem paradigmais éticos e operacionais na utilização das bodycams; estudar e comparar análises presentes na literatura a respeito da eficiência, os desafios e os resultados do uso destas ferramentas. Para atingir os objetivos propostos, o estudo tem fundamentação a partir de uma revisão de literatura de natureza básica e qualitativa, em estudos que tiveram como pauta central a discussão sobre os pontos positivos e negativos das chamadas bodycams, os desafios da implementação e quais resultados já estão disponíveis para apreciação. A justificativa do estudo está diretamente atrelada ao estado da arte do tema, onde existem estudos específicos (estudo de caso) de algumas situações de implementação em certas cidades ou regiões, bem como pesquisas de caráter mais conceitual; a revisão destas bibliografias se mostra relevantes.

Deslizamentos de terra são um grave problema em todo o Brasil, devido à presença de terrenos íngremes, chuvas intensas e solos instáveis. Esses eventos causam danos materiais significativos, interrupção de serviços e representam riscos à vida humana. Diante dessa realidade, foi proposto um estudo que visa abordar essa questão por meio de um sistema inovador. O sistema proposto consiste em uma estaca de monitoramento de áreas de risco, equipada com sensores que coletam informações do local. Esses dados são enviados por meio de comunicação via rádio. Para visualizar as informações, foi desenvolvido um aplicativo específico. Esse aplicativo permite visualizar os dados coletados e, mais importante, emite alertas em tempo real caso ocorra movimentação de massa. Um aspecto crucial do sistema é a sua capacidade de comunicação sem fio. Utilizando tecnologia LoRa, dispensa-se a necessidade de cabos de alimentação e conexão à internet, tornando-o uma solução eficiente para transmitir informações em áreas de difícil acesso. Assim reduzindo custos e aumentando a eficiência do monitoramento. Com o intuito de avaliar a percepção sobre esse sistema de monitoramento, foi realizado um questionário junto a geólogos e funcionários da Defesa Civil da região do Vale do Itajaí. Os resultados da pesquisa revelaram uma oportunidade promissora para a implementação de um protótipo do sistema proposto. A aceitação da tecnologia LoRa como meio de comunicação reforçou sua viabilidade, considerando sua capacidade de fornecer informações de forma eficaz, mesmo em áreas remotas. Esse estudo destaca a importância de soluções tecnológicas avançadas no monitoramento de deslizamentos de terra.

Working capital primarily consists of a company’s current assets, or the part of its financial resources that are converted from one kind of resource to another as operations are carried out on a daily basis. Working capital management is regarded as a key component of a company’s profitability. This study examines the working capital relationship with firm’s profitability. An optimal working capital is essential for enhancing the value of an organization. The impact of GST is significantly evident on all transactions of FMCG sectors, especially during stock transfer between two branches of a company, during which period the funds get blocked. This study considered 55 FMCG manufacturing firms, listed in BSE for a period of 12 years starting from 2012 to 2023. Multiple regression model was used to test the hypothesis. The study established a low working capital turnover ratio, which indicates quick realization of inventory, and creates the demand for funds to procure more stock for production purpose. The working capital turnover was used to gauge aggressive investing practices. An aggressive investment strategy is indicated by a low working capital turnover ratio, and a conservative strategy is indicated by a high ratio.
