Construction of intelligent campus tennis players' body data monitoring and injury warning system based on data fusion / Construção de sistema inteligente de monitoramento de dados corporais e alerta de lesões para jogadores de tênis baseado na fusão de dados / Construcción de un sistema inteligente de monitoreo de datos físicos y alerta temprana de lesiones para jugadores de tenis del campus basado en la fusión de datos

ABSTRACT As far as competitive sports are concerned, scientifically organizing the training process and strictly following the training rules are the only way to success. Tennis is the foundation of all sports. It develops physical and motor skills in a comprehensive and effective manner. Biomechanical diagnosis is mainly carried out on the basis of force-time curve recording of different movement modes, and the generated data is processed by computer through a special measuring device. The main purpose of this study is to use data fusion technology to analyze and evaluate the injury factors involved in various sports. Based on this, a dynamic chain model for early warning of sports injury risk factors is established, which can provide a reference for athletes to avoid and reduce the risk of injuries and ensure normal training and competition. In tennis training, scientific training monitoring is applied to diagnose and monitor athletes' physical function and psychological state. Conduct humanized and scientific management of the training process.

RESUMO No que se refere aos esportes competitivos, a organização científica do processo de treinamento e o cumprimento estrito das regras de treinamento são a única forma de êxito. O tênis é a base de todos os esportes. O tênis desenvolve competências físicas e motoras de uma forma abrangente e eficaz. O diagnóstico biomecânico é realizado principalmente com base na gravação da curva força-tempo de diferentes modos de movimento, e os dados gerados são processados pelo computador através de um dispositivo de medição especial. O objetivo principal deste estudo é usar a tecnologia de fusão de dados para analisar e avaliar vários fatores de lesão esportiva. Com base nisso, estabelece-se um modelo dinâmico de cadeia para o alerta precoce de fatores de risco de lesão esportiva, podendo fornecer uma referência para que os atletas evitem e reduzam o risco de lesão e garantam a normalidade dos treinos e das competições. No treinamento de tênis, aplica-se o monitoramento de treinamento científico para diagnosticar e monitorar a função física dos atletas e seu estado psicológico. Conduzir a gestão humanizada e científica do processo de treinamento.

Elimination of avoidable blindness due to cataract: Where do we prioritize and how should we monitor this decade.

Background: In the final push toward the elimination of avoidable blindness, cataract occupies a position of eminence for the success of the Right to Sight initiative. Aims: Review existing situation and assess what monitoring indicators may be useful to chart progress towards attaining the goals of Vision 2020. Settings and Design: Review of published papers from low and middle income countries since 2000. Materials and Methods: Published population-based data on prevalence of cataract blindness/visual impairment were accessed and prevalence of cataract blindness/visual impairment computed, where not reported. Data on prevalence of cataract blindness, cataract surgical coverage at different visual acuity cut offs, surgical outcomes, and prevalence of cataract surgery were analyzed. Scatter plots were used to look at relationships of some variables, with Human Development Index (HDI) rank. Available data on Cataract Surgical Rate (CSR) was plotted against prevalence of cataract surgery reported from surveys. Results: Worse HDI Ranks were associated with higher prevalence of cataract blindness. Most studies showed that a significant proportion of the blind were covered by surgery, while a fifth showed that a significant proportion, were operated before they went blind. A good visual outcome after surgery was positively correlated with higher surgical coverage. CSR was positively correlated with cataract surgical coverage. Conclusions: Cataract surgical coverage is increasing in most countries at vision <3/60 and visual outcomes after cataract surgery are improving. Establishing population-based surveillance of cataract surgical need and performance is a strong monitoring tool and will help program planners immensely.
