Objectives: This study examined the correlation between the Scandinavian Stroke Scale (SSS) and the Motricity Index (MI) in acute cerebral infarction patients. Methods: We studied 75 inpatients within a month after the onset of cerebral infarction; patients were recruited from July 2012 to November 2013. We analyzed the correlation between changes in SSS and MI by pattern identification. Results: A significant moderate positive linear correlation was noted between SSS and MI in the total patient cohort and in a Fire-heat group, Dampness-phlegm group, Qi deficiency group, and Deficiency syndrome group. A significant strong positive linear correlation existed between SSS and MI in the Excess syndrome group. The Yin deficiency group showed a weak positive linear correlation, but it was not statistically significant. Conclusions: This study provides evidence that the correlation between SSS and MI in acute cerebral infarction patients could differ depending on pattern identification.

1. Objective. The aim of this study was to investigate whether dental implant exposure to the maxillary sinus cavity increases the risk of maxillary sinus complications. 2. Study design. An implant was placed bilaterally in the maxillary sinus of eight adult female mongrel dogs in a way that it penetrated the bone and mucous membrane of the maxillary sinus floor to the extent of 2 mm, 4 mm, or 8 mm. The implants were left in place for six months. 3. Results. Radiographic and histologic examinations did not show any signs of pathologic findings in the maxillary sinus of the eight dogs. 4. Conclusion. This study indicates that implant protrusion into the maxillary sinus cavity is not related to the development of sinus complications.

Thermal Management in the Electric Vehicel is essential to improve the battery performance. This paper aims at the investigating the performance of Phase Change Material to prevent the thermal runway in the EVs. The better phase change materials are identified through simulation, based on heat transfer rate through the PCM. The design of the battery module was done in auto cad and the analysis done in ANSYS CFD software. The three pcms like paraffin wax, RT and Expanded Graphite were selected for the comparison. From the simulation result it was identified that the battery pack temperature maximum is not beyond the 60℃ (safe operating temperature range) in all test condition with the Expanded Graphite pcm material. The results were validated with numerical calculation and shown good agreement based on data collected at different temperatures.
