Influence of Outdoor Volleyball on Human Cardiopulmonary Function in Haze Environment
Abstrct
Smog has always been one of the initiators that affect human health. In a severe haze environment, all functions of the human body will decline or even fail. In this paper, the influence of outdoor volleyball on human cardiopulmonary function in severe haze environment is studied. Whether heart sounds and lung sounds are normal or not can directly reflect the health status of human heart and lungs. Therefore, based on DNN (Deep Neural Network), this paper realizes the detection, separation and detection algorithm of heart and lung sounds, and analyzes the influence of outdoor volleyball on human cardiopulmonary function in Haze environment. In this paper, a set of lung sound data acquisition paradigm and evaluation method is designed, and the collected lung sounds are preprocessed by band-pass filtering to suppress noise interference. And the original features of lung sounds are extracted by using Mel spectrogram. Experimental results show that this method has high separation accuracy and robustness, the average SNR (Signal to Noise Ratio) reaches 24,307, and the error is only 0.104. It effectively improves the accuracy and recognition rate of cardiopulmonary sound separation. This shows that the improved relationship modeling method can accurately reflect the influence of outdoor volleyball on cardiopulmonary system in severe haze environment, and provides an accurate theoretical basis for outdoor volleyball training in severe haze environment.

The advent of cinema brought with it its use as a propaganda device with which to transmit ideals and doctrines. As a result, newsreels and cinema documentaries were born with the aim of showing the «most relevant» news of the country and abroad, the former with a shorter duration. In this study, the Spanish NO-DO and «Sucesos Argentinos» are used as primary sources to interpret the images and imaginaries that were projected between 1943 and 1955 on female physical culture. The intention is to understand the official discourse of both political regimes on what Argentinean and Spanish society should be like, especially by questioning those meanings about women. In total, 69 issues of NO-DO and 14 editions of «Sucesos Argentinos» have been found which aim to show female physical culture in this period. The female physical culture shown in both newsreels was aimed at strengthening women’s bodies so that they could carry out their «natural functions» (mother, wife, housewife), as well as highlighting their «inferiority» in relation to men through lower impact activities and the homogenization of bodies through clothing, and the performance of the same exercises in synchrony. And all this in countries with different regimes, but which, in the end, coincided.
