We read with great interest the recent review of benign epilepsy with centro-temporal spikes (BECTS) and child-hood absence epilepsy (CAE) by Verrotti et al. (1)BECTS and CAE are the most common epilepsy syndromes in childhood and share certain clinical features: similar age at onset, overall good prognosis, and genetic predispo-sition. Several studies have reported the coexistence of the two syndromes, and recently, Verrotti et al. analyzed 19 cases reported to have clinical features of CAE and BECTS. Among the total 19 cases, three cases had fea-tures of both syndromes contemporarily;three cases expe-rienced absence seizures initially followed by BECTS;and the other 13 cases experienced BECTS at onset and had absence seizures later.

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.

Multicast technology application has been widely utilized in broadband internet. Source authentication is one of the most needs for many multicast applications transferring real-time information such as stream video and online news. Because multicast current services provided to the group members are changed dynamically, data transferring by a group member is not used by the recipient. In order to verify the identity of the sender who sent the packet and to make sure that the data have not been tampered, an optimized source authentication scheme has been proposed to transfer the authentication information not to the next-door packet. The proposed method for multiple packets authenticates the source with a limited number of electronic signatures. The proposed method can reduce overhead compared to the method by adding a digital signature for every packet. In addition, by sending the generated electronic signature to the first packet and the last packet, it prevents the loss of consecutive packets, as well as a source authentication can be provided in real-time services.

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.

Information analysis of high dimensional data was carried out through similarity measure application. High dimensional data were considered as the a typical structure. Additionally, overlapped and non-overlapped data were introduced, and similarity measure analysis was also illustrated and compared with conventional similarity measure. As a result, overlapped data comparison was possible to present similarity with conventional similarity measure. Non-overlapped data similarity analysis provided the clue to solve the similarity of high dimensional data. Considering high dimensional data analysis was designed with consideration of neighborhoods information. Conservative and strict solutions were proposed. Proposed similarity measure was applied to express financial fraud among multi dimensional datasets. In illustrative example, financial fraud similarity with respect to age, gender, qualification and job was presented. And with the proposed similarity measure, high dimensional personal data were calculated to evaluate how similar to the financial fraud. Calculation results show that the actual fraud has rather high similarity measure compared to the average, from minimal 0.0609 to maximal 0.1667.
