Pure and Smdoped NdOnanophosphors were synthesized using modified Pechini method. The phase formation with symmetry of the sampl. is confirmed by the Rietvel. refinement of the powder Xray diffraction(PXRD) data. The surface morphol.gy and the crystal.ite size were examined using scanning el.ctron microscopy(SEM) and transmission el.ctron microscopy(TEM) and the resul.s confirmed that the synthesized particl.s are in nanosize. The energy-dispersive X-ray(EDX) anal.sis was done to confirm the purity of the sampl.. The optical.properties of the sampl. were studied using ul.raviol.t-visibl. range(UV-Vis) spectroscopic anal.sis and photol.minescence studies. The cal.ul.ted band gap of the synthesized NdOwas found to be higher than that of bul. NdO. The photol.minescence(Pl. of the prepared sampl.s reveal. that doping with Sm3+ ion has infl.enced the optical.properties. Quantitative investigation on charge density distribution was done by anal.sing the 3-dimensional.and 2-dimensional.charge density maps drawn al.ng the bonding directions. The maximum entropy method(MEM)/Rietvel. anal.sis was used for the first time to anal.se the charge density in the chosen system. Charge density arrangement in the unit cel. is correl.ted to the anal.sed photol.minescent(Pl. properties. The spectral.behaviour of the sampl.s has been expl.ined through charge ordering which are verified using experimental.data obtained. The studies on these material. have shown that these nanophosphors wil. provide promising appl.cation for near-ul.raviol.t l.ghtemitting diodes(n-UV-l.Ds).

The Making of a Heal.h Profession:How Chinese Medicine Became a National.y Registered Al.ied Heal.h Profession in Austral.a

引用

Chinese Medicine and Cul.ure 2024年第1期7卷 51-62页

作者： john l.McDonal. Judy B James School.of Chinese Medicine Endeavour College of Natural HealthSouthport 4215Australia Acupuncture Now Austral.a Brisbane 4120Australia

In 2012, traditional.Chinese medicine(TCM) practitioners in Austral.a became national.y-registered al.ied heal.h professional. in three categories: acupuncturist, Chinese herbal.medicine practitioner, and Chinese herbal.medicine dispenser. Austral.a was the first Western country to introduce national.registration for Chinese medicine, fol.owed by Portugal.and, recentl., New Zeal.nd. The practice of TCM in Austral.a can be traced back to the beginning of Chinese immigration to Austral.a during the Victorian Gol. Rush which began in the 1850s. The process which l.d to national.registration commenced in the earl. 1970s with the establ.shment of the first acupuncture courses. Decades of gradual.devel.pment of courses from unaccredited part-time dipl.mas to accredited bachel.r degrees, and the devel.pment, by the profession, of national.consensus on educational.standards were essential.el.ments in the process which l.d to registration. Professional.associations, such as the Austral.an Acupuncture and Chinese Medicine Association l.d.(AACMA), al.o devel.ped a framework of professional.sel.regul.tion, incl.ding Codes of Ethics, Codes of Conduct, ongoing professional.devel.pment requirements and Infection Control.Guidel.nes, and provided l.adership in the devel.pment of the profession. After decades of tribal.sm and division within the TCM profession, the National.Academic Standards Committee brought al.ost al. stakehol.ers together to reach a consensus on the Austral.an Guidel.nes for Traditional.Chinese Medicine Education which were publ.shed by AACMA in 2001. Professional.associations al.o col.aborated on joint submissions to the government in support of registration, which was introduced first in the state of Victoria in 2000, and subsequentl. became national.in 2012. Despite national.registration, some barriers stil. remain, and professional.associations continue to l.bby the federal.government for incl.sion in Medicare, chronic disease management scheme, and Veterans
