Management of febrile infants,especially those younger than 3 months of age,is of clinical importance due to the relatively high risk of serious bacterial infection(SBI),such as bacterial meningitis,bacteremia,or urinary tract infection(UTI)[1].Fortunately,reliable guidelines for assessing the risk of SB I in febrile infants have been developed to help determine whether an infant should be hospitalized,undergo lumbar puncture,or be treated with antibiotics[2].However,many hospitals do not have written institutional guidelines,so clinicians often make decisions based on their own experience and knowledge[3-5].For a consistent approach to febrile infants,our hospital plans to introduce written *** this study,we estimated the expected effects of these guidelines and compared our data with the results of previous domestic studies.

Felines use their spinal column to increase their running speed at rapid locomotion performance. However, its motion profile behavior during fast gait locomotion has little attention. The goal of this study is to examine the relative spinal motion profile during two different galloping gait speeds. To understand this dynamic behavior trend, a dynamic motion of the feline animal （Felis catus domestica） was measured and analyzed by motion capture devices. Based on the experiments at two different galloping gaits, we observed a significant increase in speed （from 3.2 m.s-1 to 4.33 m.s-1） during the relative motion profile synchronization between the spinal （range： 118.86~ to 168.00~） and pelvic segments （range： 46.35~ to 91.13~） during the hindlimb stance phase （time interval： 0.495 s to 0.600 s）. Based on this discovery, the relative angular speed profile was applied to understand the possibility that the role of the relative motion match during high speed locomotion generates bigger ground reaction force.
