Upright pentacle is the symbol with many meanings and origins. http://www.religioustolerance.org/wic_pent.htm http://www.witchvox.com/basics/pentacle.html http://www.akashanpathways.com/pentagram_pentacle.htm Wiccans apprently call it the symbol of life. BTW, the five arms represent the four elements plus spirit, and as Phil says, a (or alpha) stands for air. Could that J actually be gamma? It would be Earth, and the sign would make kinda sense. And, yes, Hippocrates from Kos and the caduceus.
