然而，本研究欲探讨旅馆房务部人力资源的运用及管理，因此针对一家个案观光旅馆之房务员的洁房作业进行动作与时间研究，将所测量所得的时间视为工作绩效之一，目的在於制定洁房的标准时间及标准作业流程，并深入探讨影响房务员洁房时间的因素，同时本研究也想了解房务员之工作满意度及服务态度与其洁房时间的关系，因此本研究亦采用参与观察及深度访谈来搜集个案房务员对工作满意度与服务态度之质化资料，同时运用专家意见法来评量个案房务员之工作绩效，藉以探讨个案房务员之工作满意度、服务态度与工作绩效之间的关系。

Methods:The depth of the anterior and posterior rims of foramen magnum and the angle between medulla oblongata and upper spinal cord on midsagittal SE or FSE T1WI were measured in 320normal Chinese individuals and in 36patients with basilar impression.

随机选取320例没有颅颈交界区相关的临床症状及体症，MRI扫描无明显颅骨破坏性病变和颅颈交界区畸形的正常国人和36例颅底凹陷症患者的颅脑MRI图像，于正中矢状面SE或FSE T_1WI图像上测量枕大孔前、后缘中点深度和延髓-上颈髓轴线夹角数值。正常人按性别、年龄分16组，每组20例。

Purpose:To determine the normal ranges of the depth of the anterior and posterior rims of foramen occipital magnum and the angle between medulla oblongata and the upper spinal cord on midsagittal MRI in normal Chinese idividuals and patients with basilar impression,to study their clinical significance and to provide normal reference in diagnosing basilar invagination by MRI.

目的：利用颅脑正中矢状面MRI自旋回波或快速自旋回波T_1WI图像测量颅颈交界区正常的中国人和颅底凹陷症患者枕大孔前、后缘中点深度和延髓-上颈髓轴线夹角数值，评价其正常值范围，探讨其发育规律及临床意义，为MRI诊断颅底凹陷症提供直接的参考标准。
