Aim: The aim of this study was to evaluate the quality of the performance of everyday activities in children with spina bifida.
Methods: Fifty children with spina bifida (of 65 children in a geographic cohort), aged 6 to14 years, were evaluated with Assessment of Motor and Process Skills.
Results: Compared with age-normative values, 60% of the children with spina bifida were found to have motor ability measures below 2 SD and 48% process ability measures below 2 SD. Most of the children with spina bifida had difficulties performing well-known everyday activities in an effortless, efficient and independent way, relating to both motor and process skills. The motor skills hardest to accomplish involved motor planning and the process skills hardest to accomplish were adaptation of performance and initiations of new steps, thus actually getting the task done.
Conclusion: To reach autonomy in life, children with spina bifida may need particular guidance to learn not only how to do things but also how to get things done. 相似文献

Given the increasing volume of radiological exams, the decreasing frequency of direct communication with the referring provider,
and the distribution of patient data over many clinical systems, radiologists often do not have adequate clinical information
at the time of interpretation. We have performed a survey of radiologists to determine the need and actual utilization of
patient data at the time of image interpretation. Our findings demonstrate that most radiologists want more clinical information
when interpreting images and that this information would impact their report, but they are discouraged by the time it takes
to access this information. In addition, current mechanisms for monitoring necessary patient follow-up are inadequate. 相似文献

Raman spectroscopy was used to design and monitor a lysozyme protein batch crystallization process in a lab scale study to
facilitate the design of a pharmaceutical protein manufacturing process. A D-optimal design that consisted of 18 experiments
was performed to elucidate the effect of temperature, concentration of the precipitating agent, time of crystallization, and
possible interactions between these three factors on the Raman scattering changes. A polynomial mathematical model was calculated
relating the scattering of the lysozyme solutions measured at individual Raman shifts to the significant factors obtained
in the previous crystallization experiment. The 2,940-cm−1 band provided the highest correlation values indicative of small prediction errors and good predictive ability for the crystallization
model. Raman scattering signals obtained during the experiments were used as input to obtain a response surface for the factors
studied and elucidate the relationship between the crystallization process conditions and the crystals obtained. The main
factors affecting the crystallization process were the sodium chloride concentration and temperature. 相似文献

试论医院流程化管理形成的基础——过程方法 总被引:10,自引:0,他引:10
李杰 《中华医院管理杂志》2007,23(8):568-570
一些医院采用了流程化方式进行医院管理活动,由于普遍存在着对流程机制、实质内涵以及流程管理认识和操作能力上的不足,因此收到的效果不大。医院流程化管理的基础应是对过程进行的科学规范化的管理,应采用先进的“过程方法”理论和手段对现有的医院流程内容进行完善和改进,切实提高组织流程化管理水平。 相似文献
