AI brings gamechanging approaches for soccer analytics where soccer has been a typical benchmark for AI research. The combination has been an emerging topic. In this paper, soccer match analytics are taken as a complete observation-orientation-decision-action(OODA) loop.In addition, as in AI frameworks such as that for reinforcement learning, interacting with a virtual environment enables an evolving model. Therefore, both soccer analytics in the real world and virtual domains are discussed. With the intersection of the OODA loop and the real-virtual domains, available soccer data, including event and tracking data, and diverse orientation and decisionmaking models for both real-world and virtual soccer matches are comprehensively reviewed. Finally, some promising directions in this interdisciplinary area are pointed out. It is claimed that paradigms for both professional sports analytics and AI research could be combined. Moreover, it is quite promising to bridge the gap between the real and virtual domains for soccer match analysis and decision-making.展开更多

This study examined the impact of workplace-based sports participation on the mental status of Japanese workers. It involved a single-arm intervention comprising participation in a company’s volleyball team. Data on mental status were collected using a simplified version of the Brief Job Stress Questionnaire. Overall, 11 individuals participated, 9 (81.8%) of whom were women;the mean participant age was 38.2 years. Because the intervention was conducted during busy periods, the median (25th and 75th percentiles) score for qualitative job overload significantly increased from 3.0 (2.0, 4.0) to 3.0 (3.0, 4.3) (p = 0.03). Nonetheless, the fatigue score significantly decreased from 3.0 (3.0, 4.3) to 3.0 (2.0, 4.0) (p = 0.03). These results indicate that participation in workplace-based sports can prevent the deterioration of mental status during busy periods.展开更多

Objective: The objective of this study was to identify the factors of the failure of its treatment by the Ponseti method. Material and Method: We carried out a retrospective and descriptive study of cases of congenital equinus clubfoot varus at the Reference Health Care Center of Commune III of Bamako over 26 months from September 2020 to November 2022. Data were treated with the utmost anonymity. Result: This study was performed on 44 children seen for clubfoot: male (68%) and female (32%), with a sex ratio of 2.1. We obtained 13 cases of recidivism including 7 boys and 6 girls. We found 21 cases of unilateral and 23 bilateral;among which 9 recurrences were found against 4 in the unilateral forms. 85% of recurrences did not have good adherence to the splint and 62% did not come regularly for follow-up consultation. We obtained 33 children with idiopathic clubfeet (75%) with a recurrence of 24%, and 7 children with secondary clubfeet with 71 % recurrence. There was no recurrence in the postural type. Among the recurrences, 38.5% started treatment between 1 and 6 months, 23.1% from 0 to 1 month and 15.4% at 2 years and more. 85% of recurrences had a Pirani score between 4.5 to 6 at the start of treatment and 15% at a score of 2.5 to 4. Conclusion: The factors of the failure of the Ponseti method are mainly non-compliance with treatment, secondary clubfeet, and a high Pirani score at the start of treatment.展开更多

文摘Composite fabrics based on Polytetrafluoroethylene(PTFE)polymer displays several notable properties.They are waterproof,windproof,permeable to moisture and thermally insulating at the same time.In the present study,PTFE fibers are used as raw material to make fiber membranes.The film is formed by crisscrossing interconnected fiber filaments and the related air permeability:tensile creep characteristics and other properties are tested.The results show that the pore size,thickness,and porosity of the film itself can affect the moisture permeability of the film.The water pressure resistance of the selected fabric is 8.5 kPa,and the moisture permeability is 7038 g/(m^(2)·24 h).
文摘BACKGROUND Epidemiological understanding of acute sternoclavicular(SC)dislocations secondary to sports across the United States is poorly defined.AIM To identify and assess epidemiological trends of SC dislocations occurring secondary to sports-related mechanisms across United States over the past two decades.METHODS This cross-sectional,descriptive epidemiological study evaluates epidemiological trends of SC dislocations from sports that present to emergency departments(EDs)across the United States.Data were obtained from the National Electronic Injury Surveillance System database spanning two decades.Data on incidence,patient demographics,mechanisms of injury,dislocation types,incident locales,and patient dispositions were collected.RESULTS 1622 SC dislocations occurred nationwide from 2001 to 2020[incidence=0.262/1000000 people,confidence interval(CI)=0.250-0.275],comprising 0.1%of shoulder/upper trunk dislocations.Most patients were male(91%,n=1480)and aged 5-17(61%,n=982).Football,wrestling,and biking were the most frequently implicated sports,with contact sports responsible for 59%of athletic injuries(n=961).Recreational vehicle-related sports injuries,such as all-terrain vehicles,dirt bikes,and mopeds accounted for 7.8%of all injuries(n=126),with dirt bikes specifically comprising 3.7%(n=61).Ultimately,82%were discharged from the ED(n=1337),12%were admitted(n=194),and 6%were transferred(n=90).All recorded posterior dislocations were admitted or transferred from the ED.Patients sustaining SC dislocations from contact sports had a significantly increased risk of hospital admission or transfer rather than discharge from the ED as compared to patients whose injuries were from non-contact sports(incidence rate ratio=1.46,CI:=1.32-1.61,P<0.001).CONCLUSION SC dislocations from sports continue to be rare with a stably low incidence over the past two decades,likely comprising a smaller proportion of shoulder dislocations than previously thought.Contact sports are a frequent source of injury,especially among school-aged and teenage males.Most patients are discharged directly from the ED;however,a substantial number are hospitalized,many of which had documented posterior dislocations.Ultimately,understanding the epidemiology and mechanism-related trends of acute SC dislocations is important given the potential severity of these injuries,concentration in a specific population,and uncertainty linked to rare presentation.
文摘With China’s continued development of society and economy, the importance of ecological environmental protection is growing. This protection has become an indispensable part of social development. The use of various green environmental protection equipment can effectively promote ecological environmental protection and reduce the adverse effects of human activities on the environment. In the field of sports lighting equipment in China, traditional lighting methods constitute an inherent danger to the environment, leading to a waste of valuable resources and environmental pollution. This study involves a multi-tile-multifunctional-function controller, which effectively solves the control problem of the control light. In the sports lighting group, the high and low-level lighting of the sports lighting group, and adjust the light from the height highly effectively to adjust each height. The low-shot mode reduces the power consumption of the system by about 33% to 60%, which significantly helps energy saving. By optimizing the performance of the lighting system, promoting the preservation of power resources, reducing the adverse effects of pollution caused by equipment utilization and energy waste, and promoting the harmonious cohabitation of human and natural environment. .
