一种基于最优个体保存策略的服务组合优化选取方法

提出了一种基于遗传算法的Web服务选取方法,使得组合形成的增值服务不仅能完成预定义任务,还能满足用户的特定需求。 该方法采用动态适应度函数,提高了服务组合的适应度,通过计算个体间服务质量的海明距离和实施最优个体保存策略,提高了服 务组合的质量。实验结果证明了该方法的有效性。     

基于移动终端的病区营养订餐系统开发及应用

传统手工订餐方式在营养配餐、订餐管理、绩效管理、食材管理、财务管理等方面存在诸多弊端,已难以适应现代医院精细化管理要求。通过开发基于移动终端的病区营养订餐系统,可以实现了点餐、统计、营养咨询、测评的科学管理,在提高工作效率、改善服务质量、增加财务透明度、提供决策支持、实现多院区的共同管理方面获得较好的应用效果。     

301模式就医一卡通信息系统在预约诊疗中的应用

近年来,在新医改的助推下,为满足患者不断增长的就医需求,缓解日益凸显的看病难问题,预约诊疗在国内应运而生。预约诊疗在全国范围内的开展,有效地提高了患者就医可及性和便利性。目前国内预约诊疗大部分还停留在预约挂号阶段,尚未实现就医全流程预约管理。“301模式便民就医一卡通”信息系统,响应国家开展预约诊疗的号召,为开展多种形式的预约诊疗服务提供了可借鉴的成功案例。

Epidemiology of Cheerleading Fall-Related Injuries in the United States

Context:

Over the past several decades, cheerleaders have been performing fewer basic maneuvers and more gymnastic tumbling runs and stunts. As the difficulty of these maneuvers has increased, cheerleading injuries have also increased.

Objective:

To describe the epidemiology of cheerleading fall-related injuries by type of cheerleading team and event.

Design:

Prospective injury surveillance study.

Setting:

Participant exposure and injury data were collected from US cheerleading teams via the Cheerleading RIO (Reporting Information Online) surveillance tool.

Patients or Other Participants:

Athletes from 412 enrolled cheerleading teams who participated in official, organized cheerleading practices, pep rallies, athletic events, or cheerleading competitions.

Main Outcome Measure(s):

The numbers and rates of cheerleading fall-related injuries during a 1-year period (2006–2007) are reported.

Results:

A total of 79 fall-related injuries were reported during the 1-year period. Most occurred during practice (85%, 67/79) and were sustained by high school cheerleaders (51%, 40/79). A stunt or pyramid was being attempted in 89% (70/79) of cases. Fall heights ranged from 1 to 11 ft (0.30–3.35 m) (mean  =  4.7 ± 2.0 ft [1.43 ± 0.61 m]). Strains and sprains were the most common injuries (54%, 43/79), and 6% (5/79) of the injuries were concussions or closed head injuries. Of the 15 most serious injuries (concussions or closed head injuries, dislocations, fractures, and anterior cruciate ligament tears), 87% (13/15) were sustained while the cheerleader was performing on artificial turf, grass, a traditional foam floor, or a wood floor. The fall height ranged from 4 to 11 ft (1.22–1.52 m) for 87% of these cases (13/15).

Conclusions:

Cheerleading-related falls may result in severe injuries and even death, although we report no deaths in the present study. The risk for serious injury increases as fall height increases or as the impact-absorbing capacity of the surfacing material decreases (or both).     

Are Elite Collegiate Female Athletes PRIME for a Safe Return to Sport after ACLR? An Investigation of Physical Readiness and Integrated Movement Efficiency (PRIME)

BackgroundElite female athletes who successfully return to sport after anterior cruciate ligament reconstruction (ACLR) represent a high-risk group for secondary injury. Little is known about how the functional profile of these athletes compares to their teammates who have not sustained ACL injuries.PurposeTo compare elite collegiate female athletes who were able to successfully return to sport for at least one season following ACLR to their teammates with no history of ACLR with regard to self-reported knee function, kinetics, and kinematics during a double limb jump-landing task.Study DesignCross-Sectional StudyLevel of EvidenceLevel 3MethodsEighty-two female collegiate athletes (17 ACLR, 65 control) completed the knee-specific SANE (single assessment numeric evaluation) and three trials of a jump-landing task prior to their competitive season. vGRF data on each limb and the LESS (Landing Error Scoring System) score were collected from the jump-landing task. Knee-SANE, vGRF data, and LESS scores were compared between groups. All athletes were monitored for the duration of their competitive season for ACL injuries.ResultsAthletes after ACLR reported worse knee-specific function. Based on vGRF data, they unloaded their involved limb during the impact phase of the landing, and they were more asymmetrical between limbs during the propulsion phase as compared to the control group. The ACLR group, however, had lower LESS scores, indicative of better movement quality. No athletes in either group sustained ACL injuries during the following season.ConclusionDespite reporting worse knee function and demonstrating worse kinetics, the ACLR group demonstrated better movement quality relative to their uninjured teammates. This functional profile may correspond to short-term successful outcomes following ACLR, given that no athletes sustained ACL injuries in the competition season following assessment.
