This study assessed the feasibility of doing hearing screening in Migrant, American Indian and Early Head Start programs using otoacoustic emissions (OAE) technology. Staff members were trained to screen 0–3-year-old children for hearing loss using hand-held OAE equipment and a multi-step screening and referral protocol. Of the 3486 children screened as a part of the study, 77% passed an OAE screening at the first step, 18% more passed an OAE screening at the second step, and 5% were ultimately referred for medical or audiological follow-up. Eighty children were identified as having a hearing loss or disorder of the outer, middle or inner ear requiring treatment. Of these 80, six had permanent bilateral or unilateral hearing loss. Although the protocol suggested that the multi-step screening procedure should be completed within a 4-week time period or less, analysis of the data showed that for children requiring more than an initial OAE screening, the length of time over which the screening was completed ranged from 7 to 12 weeks. The median time required to complete a single OAE screening session was 4 minutes per child. The results demonstrate that OAE screening of young children using this protocol is practical and effective. The implications for conducting periodic hearing screening throughout early childhood are discussed. 相似文献

A survey of all Illinois community and senior institutions was conducted to determine which noncollegiate learning experiences are awarded credit. The survey showed that most institutions credit some kinds of noncollegiate learning, although the extent varied by validation modes. Public community colleges appear to be most receptive to crediting noncollegiate experiences, but overall, the awarding of credit appears to be related to the ease of using the validation mode and the length of time the system has been in use. 相似文献

广枣提取液对小鼠免疫功能和运动耐力的影响 总被引：11，自引：0，他引：11
观察了广枣提取液对小鼠免疫功能、运动耐力的影响。结果表明：广枣提取液可明显增加小鼠耐缺氧时间，延长小鼠负重游泳时间，降低运动后小鼠血乳酸水平，显著提高其心肌组织中SOD活力；同时明显增加小鼠脾脏／体重、胸腺／体重比值，增强小鼠对巨噬细胞的吞噬能力．提高小鼠的细胞免疫、体液免疫功能。提示广枣提取液具有显著促进小鼠免疫功能及显著提高小鼠运动耐力的功效。 相似文献
