项目摘要

In order to observe the sleep-awake states of infants and identify the characteristics of these states, efforts were devoted to developing software that can objectively collect data and analyze it. This system focused on infant body movement, based on observation and analysis methods using videosomnography.In 2004, the system was developed and the software almost completed. The time-lapse video set/system was changed to a digital camera and computer, reducing weight and enabling acquisition of digital data.In 2005, a trial was conducted to validate the reliability of the software, where already-analyzed video data was read by the software and the earlier results were compared against the analysis results of the new software system. However, the image quality of the analogue video data was rough and subtle analysis was difficult, so analysis was stopped. Accordingly, the video was digitalized for legacy migration only. To save the image data, a hard disk was used connected to the required large capacity LAN.In 2006, in order to validate the reliability of the software, an Actiwatch was also used while collecting infant data. When data of 9 infants one month postpartum was analyzed, motion detection was activated other than for direct infant movement for an average 6.0% out of an average recording time of 9.3 hours. Reliability using the Actiwatch was demonstrated by Spearman's rank correlation coefficient.During the whole development period of this system, the author participated in domestic and overseas sleep research conferences, etc. and through presentations received feedback from sleep researchers. In trials conducted with overseas joint researcher Dr. Thomas F. Anders (Department of Psychiatry and Behavioral Sciences, UC Davis, M.I.N.D. Institute), the system was refined. Further development issues that became clear are the method of automatic analysis, and the addition of voice data and vital data (breathing).
为了观察婴儿的睡眠-觉醒状态,并确定这些状态的特征,致力于开发能够客观地收集数据并进行分析的软件。该系统以婴幼儿身体运动为研究对象,采用视频睡眠学的观察分析方法,于2004年开发完成,软件基本完成。将延时视频设备/系统改为数码相机和计算机,减轻了重量,使数字数据的获取成为可能。2005年,进行了一次验证软件可靠性的试验,软件读取已分析的视频数据,并将早期结果与新软件系统的分析结果进行比较。然而,模拟视频数据的图像质量较差,难以进行精细分析,因此停止了分析。因此,该视频被数字化,仅用于遗留迁移。为了保存图像数据,使用了连接到所需大容量局域网的硬盘。2006年,为了验证软件的可靠性,还使用了Actiwatch来采集婴儿数据。当分析9名产后1个月婴儿的数据时,除直接婴儿运动外,平均6.0%的婴儿运动检测被激活,平均记录时间为9.3小时。通过Spearman等级相关系数验证了Actiwatch使用的可靠性,在该系统的整个开发过程中,作者参加了国内外睡眠研究会议等,并通过演讲收到了睡眠研究人员的反馈。在与海外联合研究员托马斯·F·安德斯(Thomas F.Anders)博士(加州大学戴维斯分校精神病学和行为科学系,M.I.N.D.Institute)进行的试验中,该系统得到了改进。进一步的开发问题变得清晰起来,是自动分析的方法,以及添加语音数据和重要数据(呼吸)。
