Avaliação de fatores de risco para quedas utilizando como instrumento o teste Timed Up and Go (TUG) associado à mini avaliação do estado nutricional (MNA) em pacientes idosos portadores de osteoporose primária atendidos em hospital universitário
Authors: Souza Samuel Lucca Fontes de
Published: January 2025

Introdução: a desnutrição é uma afecção bastante prevalente em idosos, atinge ambos os sexos e acelera as perdas de massa óssea e muscular, o que, junto à redução dos reflexos, acentua o risco de quedas nessa faixa etária. A mobilidade funcional é um dos fatores associados à capacidade do paciente de se manter estável para realizar atividades habituais, sendo importante para evitar quedas e fraturas, principalmente em pacientes com OP (Osteoporose Primária), devido à fragilidade óssea acentuada. O objetivo desse estudo foi avaliar de forma objetiva a relação entre a mobilidade funcional e a desnutrição em pacientes idosos com diagnóstico de OP. Metodologia: Trata-se de um estudo transversal e observacional que incluiu pacientes com 60 anos ou mais com Densitometria Óssea (DMO) ≤ -2,5 DP nos últimos 12 meses, sem doenças hormonais ou osteometabólicas que pudessem justificar uma OP secundária.  A desnutrição foi avaliada através da Mini Nutricional Assessment (MNA) e a mobilidade funcional foi avaliada através do Teste Timed Up and Go (TUG). Os valores de idade, TUG e MNA foram descritos com mediana e intervalo interquartil. A correlação entre TUG e MNA foi calculada usando o coeficiente de correlação de postos de Spearman. Posteriormente, o MNA foi dividido em categorias 1 (Estado nutricional normal) e 2 (sob risco de desnutrição e desnutrição) e avaliado se há diferença nos valores  do TUG através do teste U de Mann-Whitney. Resultados: O estudo contou com 48 pacientes (73 ± 9.50 anos de idade), sendo 45 do sexo feminino e 3 do sexo masculino, sendo analisado TUG (13.70 ± 8.32) e MNA (26.00 ± 2.63). O estudo mostrou uma correlação negativa  entre TUG e MNA (- 0.444  p- = 0.002). Quando categorizada a MNA em 1 e 2 e comparada com o TUG, encontrou-se uma diferença estatisticamente significativa com indivíduos na categoria tendo maiores valores de TUG (p = 0.014). Conclusão: De acordo com as análises supracitadas, os pacientes que apresentaram desnutrição ou risco de desnutrição através do MNA tenderam a uma menor mobilidade funcional de acordo com o TUG, quando comparados aos pacientes sem desnutrição. O estudo mostrou uma correlação estatisticamente significativa entre TUG e MNA. Dessa forma, nesta população, a desnutrição demonstrou ser um fator de risco importante para quedas devido à menor mobilidade funcional, o que resulta em um menor equilíbrio e maior fragilidade.

Authors: Duziyelebai Dilida , Zhuang Yugang
Published: January 2025

Mechanical ventilation is clinically used to assist in the gas exchange for patients who need to maintain adequate alveolar ventilation. Its common indications include respiratory failure, heart failure, drug overdose, and surgery. Although mechanical ventilation can save the lives of patients with respiratory failure, prolonged use can lead to diaphragm atrophy and contraction dysfunction. Currently, there is a lack of effective assessment and monitoring methods for diaphragm dysfunction in clinical practice, leading to insufficient attention to diaphragm function. Understanding the pathophysiological process of diaphragm dysfunction, assessment methods, and prevention and treatment strategies is crucial for improving the prognosis of ICU patients on mechanical ventilation. This paper briefly introduces the pathogenesis of diaphragm dysfunction, current assessment methods, and prevention and treatment strategies, hoping to provide some assistance to clinical practice.

Evaluation Method for Road Area Coverage of Roadside Surveillance Cameras
Authors: Song Jiaman
Published: January 2025

As the number of surveillance cameras has increased rapidly, the issues of coverage blindness, coverage overlap and lack of vision resulting from an irrational surveillance layout have become increasingly prominent. This has led to a waste of resources and a reduction in surveillance quality. The conventional methodology for evaluating road coverage is inadequate for accurately assessing the actual monitoring capacity of the camera. In light of the aforementioned issues, this paper puts forth a novel road coverage assessment method based on the monitoring camera perception model. This approach integrates the monitoring coverage calculation methods in two-dimensional and three-dimensional spatial dimensions, considers road coverage under both single and multiple monitoring deployment scenarios, and employs GIS spatial analysis technology to achieve a comprehensive assessment of the monitoring camera network coverage. The findings demonstrate that the proposed methodology is capable of accurately calculating the coverage of surveillance cameras under diverse pitch angles and the extent of duplicate coverage areas in multi-camera deployments. It enhances the overall coverage and precision of the surveillance network, and provides a scientific foundation and practical guidance for the design and planning of road surveillance networks.

Study on the Bridge Plugging Law of Pipeline Particles in Liquid-Solid System
Authors: Liu Zhen , Lv Sen , Ma Xiaohua , Liu Chenwei
Published: January 2025

Bridge plugging of solid particles is a common phenomenon in the field of oil and gas engineering, and it mostly occurs in liquid-solid. However, as a basic problem involving many fields, the current research focuses on the funnel flow system driven by gravity, and the exploration of liquid phase driving system is relatively few. In this paper, a visual particle pipeline bridge plugging test system was constructed and evaluated. The particle bridge plugging test experiment with particle/pore size ratio between 0.26-0.6 in liquid-solid system was carried out, and the influence of particle/pore size ratio on bridge plugging was analyzed. The results show that when the particle/pore size ratio is less than 0.28, the pipeline will not be blocked by particles. With the increase of the particle/pore ratio from 0.39 to 0.60, the number of particles required for the particles to form a stable bridge at the hole becomes less, the easier it is to form a stable bridge blocking structure, and the probability of bridge blocking is higher. The number of particles in the flow decreases with the increase of particle/pore size ratio before particle plugging. After the plugging is formed, the upstream pressure increases sharply, the flow rate decreases sharply and tends to be stable, and the flow rate corresponding to the plugging of large particles is higher. It has important guiding significance for further clarifying the bridging mechanism of particles in the flow environment.

Authors: Gan Ziwei , Yan Yijun , Li Zhijie , Jia Chunyang
Published: January 2025

Transition metal sulfides are considered as good electrode materials for supercapacitors due to their high specific capacity and good structural stability. However, its poor multiplicative performance and limited cycle life limit its wide application. To solve this problem, we synthesized NiCo2S4/CuCo2S4 bimetallic sulphide nanocomposites by combining NiCo2S4 with CuCo2S4 using a two-step hydrothermal method. Compared with NiCo2S4 and CuCo2S4 alone, the NiCo2S4/CuCo2S4 nanocomposites have higher specific capacity and better cycling stability as supercapacitor electrodes. The specific capacity value of the NiCo2S4/CuCo2S4 electrodes at 1 A g-1 is 830.3 C g-1 with a potential window of 0-0.5 V. The NiCo2S4/CuCo2S4 nanocomposites are used as the electrodes in supercapacitors. Ni3S4 and activated carbon as cathode and anode, respectively, the hybrid supercapacitor (HSC) assembled with NiCo2S4/CuCo2S4 electrodes has a capacitance value of 129.4 F g-1 at 1 A g-1 and an energy density of up to 52.9 Wh kg-1 at 410 W kg-1. Long-term electrochemical stability tests show that the retention of the electrochemical specific capacity is 54% after 16,000 cycles.

Experimental Study on Thermal Performance of Longitudinally-Finned Heat Sink Integrating Piezoelectric Fan
Authors: Yu Liang , Huang Ying , Li Xinjun
Published: January 2025

An experimental investigation is performed to research the heat transfer performance (HTP) of a longitudinally-finned heat sink integrating piezoelectric fan. This piezoelectric fan (PF) is actuated at its first-mode resonant frequency of 51Hz and excitation voltage of 220V. The influence of PF orientation on the thermal resistance of finned heat sink is revealed under different channel flow velocity ranging from 0m/s to 8m/s. The results show that the presence of the PF has a positive effect on HTP enhancement of finned heat sink, which is tightly dependent on the channel flow velocity, PF orientation. In general, the role of PF on improving the HTP of finned heat sink behaves in the situations of low channel flow velocity, especially under free convection situation. When the PF is located tightly close to the front edge of heat sink, its orientation appears to be an important factor affecting the HTP of finned heat sink.

Authors: Liu Ruiling , Sun Xuyang
Published: January 2025

With the rapid development of data collection and storage technologies, the variety of non-Euclidean predictors in the field of quantitative finance is increasing, and how to integrate them with the information of the traditionally used Euclidean factors to improve the performance of predictive models is an important research issue. Based on this, this paper proposes an integrated learning model based on multi kernel learning and Gaussian process regression. Specifically, on the one hand, the proposed method integrates the prediction information from different sources by using different kernel functions as a measure of the difference between elements in the Euclidean and non-Euclidean spaces and based on the Gaussian process regression model. On the other hand, the method improves the prediction accuracy and overall robustness of the prediction model by using the stacking algorithm to quadratically fit the output of the Gaussian process regression model as a new input variable. In addition, the learner used in the secondary fitting is model-free. Simulation analyses illustrate the effectiveness of the proposed method under different experimental settings. Finally, by predicting real stock price data, the results show that the proposed method has a smaller prediction error compared to some classical prediction models.

Данное исследование рассматривает применение технологий об-работки естественного языка (NLP) для анализа требований к IT-проектам с целью прогнозирования их стоимости. Исследование направлено на удовлетворение крити-ческой потребности в точных и объективных методах оценки затрат на ранних стадиях разработки IT-проектов. Мы представляем новый подход, сочетающий методы NLP и машинного обучения для извлечения ключевых характеристик проекта из текстовых требований и использования их для прогнозирования затрат. Методология включает сбор данных, предобработку текста, выделение признаков с использованием передо-вых методов NLP и разработку модели машинного обучения на основе градиентного бустинга деревьев решений. Эффективность данного подхода оценивалась путем об-ширного экспериментального анализа, в котором его результаты сравнивались с тра-диционными методами оценки. Результаты показали значительное улучшение точно-сти прогнозирования затрат, с уменьшением среднеквадратичной ошибки на 40% по сравнению с оценками экспертов. Исследование также выявило ключевые факторы, влияющие на стоимость проектов, с помощью анализа важности признаков. Мы об-суждаем значение этих результатов для практики управления проектами, подчеркивая потенциал подходов на основе NLP для улучшения принятия решений при планирова-нии и выполнении IT-проектов. Данное исследование вносит вклад в развивающуюся область автоматизированного анализа проектов и предлагает ценные инсайты как для исследователей, так и для практиков в области управления IT-проектами.
