Methods Japan, South Korea, the USA and Australia were selected as the representative countries. The standards language were limited to English, Japanese and South Korean. The websites of the national standards bodies and the official websites for the acupuncture association/ institute of these four countries were searched systematically. The laws of acupuncture were included in the study. Results Technical standards made up the most of the standard system for acupuncture in Japan, basic standards accounted for the most of the system in South Korea, while management standards accounted for the largest proportion of acupuncture standard systems in the USA and Australia. Conclusion Japan and South Korea, which use acupuncture mainly due to cultural and historical influences, place emphasis on establishing technical and basic standards. The USA and Australia, which use acupuncture as a complementary therapy, place emphasis on establishing management standards of acupuncture.展开更多

Using the single- epoch precise point positioning （PPP） method and the appropriate positioning flow, we process GPS data from six IGS （International GNSS Service） sites （e.g., MIZU, TSK2, USUD, MTKA, AIRA and KSMV） located in Japan and obtain the positioning results with centimeter scale precision. The displacement time series of the six sites are analyzed using the least squares spectral analysis method to estimate deformations caused by the Mw9.0 mainshock and the Mw7.9 aftershock, and the cumulative displacements after 1 day. Mainshock displacements at station MIZU, the nearest site to the mainshock in the North （N）, East （E）, and Up （U） directions, are -1.202 m, 2.180 m and -0.104 m, respectively, and the cumulative deformations after 1 day are -1.117 m, 2.071 m and -0.072 m, respectively. The displacements at station KSMV, the nearest site to the Mw7.9 aftershock in the N, E and U directions, are -0.032 m, 0.742 m and -0.345 m, respectively. The other sites obviously experienced eastern movements and subsidence. The deformation vectors indicate that the horizontal displacements caused by the earthquake point to the epicenter and rupture. Elastic bounds evidently took place at all sites. The results indicate that the crustal movements and earthquake were part of a megathrust caused by the Pacific Plate sinking under the North American Plate to the northeast of Japan island arc.展开更多
