以抑郁症、焦虑症、强迫症为个案,对每种症状2名共6名大学生心理障碍患者进行体育疗法干预研究。在深入了解被试者情况、分析其致病原因和特点的基础上,把针对性体育疗法、一般体育疗法及心理辅导结合起来制定体育疗法方案。经过8周的体育疗法干预实验,分析体育干预前后的观察记录和问卷测评结果得出以下结论:体育疗法干预后相关因子均有所降低,被试者的身心健康得到了促进,但体育疗法对于不同程度心理障碍治疗效果不尽相同,对于中度或重度症状的干预效果好于轻度症状。

The integration of endoscopy has significantly propelled the diagnosis and treatment of gastrointestinal diseases, with colonoscopy establishing itself as the primary method for early diagnosis and preventive care in colorectal cancer(CRC). Although deep learning holds promise in mitigating missed polyp rates, modern endoscopy examinations pose additional challenges, such as image blurring and atomizing. This study explores lightweight yet powerful attention mechanisms, introducing the spatial-channel transformer(SCT), an innovative approach that leverages spatial channel relationships for attention weight calculation. The method utilizes rotation operations for inter-dimensional dependencies, followed by residual transformation, encoding inter-channel and spatial information with minimal computational overhead. Extensive experiments on the CVC-Clinic DB polyp detection dataset, addressing endoscopy pitfalls, underscore the superiority of our SCT over other state-of-the-art methods. The proposed model maintains high performance, even in challenging scenarios.
