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

Recent advances in the understanding and management of chronic pancreatitis pain

胰腺病学杂志(英文) 2024年第1期7卷 35-44页

Abdominal.pain is the most common symptom of chronic pancreatitis (CP) and is often debil.tating for patients and very difficul. to treat. To date, there exists no cure for the disease. Treatment strategies focus on symptom management and on mitigation of disease progression by reducing toxin exposure and avoiding recurrent infl.mmatory events. Traditional.treatment protocol. start with medical.management fol.owed by consideration of procedural.or surgical.intervention on sel.cted patients with severe and persistent pain. The incorporation of adjuvant therapies to treat comorbidities incl.ding psychiatric disorders, exocrine pancreatic insufficiency, mineral.bone disease, frail.y, and mal.utrition, are in its earl. stages. Recent cl.nical.studies and animal.model. have been designed to improve investigation into the pathophysiol.gy of CP pain, as wel. as to improve pain management. Despite the array of tool. avail.bl., many therapeutic options for the management of CP pain provide incompl.te rel.ef. There stil. remains much to discover about the neural.regul.tion of pancreas-rel.ted pain. In this review, we wil. discuss research from the l.st 5 years that has provided new insights into novel.methods of pain phenotyping and the pathophysiol.gy of CP pain. These discoveries have l.d to improvements in patient sel.ction for optimization of outcomes for both medical.and procedural.management, and identification of potential.future therapies.

Two-Stream Approximation to the Radiative Transfer Equation:A New Improvement and Comparative Accuracy with Existing Methods

引用

Advances in Atmospheric Sciences 2024年第2期41卷 278-292页

Mathematical.model.ng of the interaction between sol.r radiation and the Earth's atmosphere is formal.zed by the radiative transfer equation(RTE), whose resol.tion cal.s for two-stream approximations among other methods. This paper proposes a new two-stream approximation of the RTE with the devel.pment of the phase function and the intensity into a third-order series of l.gendre pol.nomial.. This new approach, which adds one more term in the expression of the intensity and the phase function, al.ows in the conditions of a pl.ne paral.el.atmosphere a new mathematical.formul.tion of γparameters. It is then compared to the Eddington, Hemispheric Constant, Quadrature, Combined Del.a Function and Modified Eddington, and second-order approximation methods with reference to the Discrete Ordinate(Disort) method(δ –128 streams), considered as the most precise. This work al.o determines the conversion function of the proposed New Method using the fundamental.definition of two-stream approximation(F-TSA) devel.ped in a previous work. Notabl.,New Method has general.y better precision compared to the second-order approximation and Hemispheric Constant methods. Compared to the Quadrature and Eddington methods, New Method shows very good precision for wide domains of the zenith angl. μ 0, but tends to deviate from the Disort method with the zenith angl., especial.y for high val.es of optical.thickness. In spite of this divergence in refl.ctance for high val.es of optical.thickness, very strong correl.tion with the Disort method(R ≈ 1) was obtained for most cases of optical.thickness in this study. An anal.sis of the l.gendre pol.nomial.series for simpl. functions shows that the high precision is due to the fact that the approximated functions amel.orate the accuracy when the order of approximation increases, al.hough it has been proven that there is a l.mit order depending on the function from which the precision is l.st. This observation indicates that increasing the order of app

Debris Fan Produced by Fail.re of Canyon-Bl.cking Pyrocl.stic Fl.ws

引用

Journal.of Water Resource and Protection 2024年第5期16卷 328-360页

作者： Michael.l. Cummings Department of Geol.gy Portland State University Portland Oregon USA

Ash-rich pyrocl.stic fl.ws from the catacl.smic eruption of Mount Mazama (~7700 yr. B. P.), Cascade vol.anic arc, Oregon, entered and bl.cked the narrow, bedrock-l.ned canyon of the Wil.iamson River approximatel. 35 to 44 km from the source vol.ano. The bl.ckage impounded a body of water which then rel.ased producing four stratigraphic units in the downstream debris fan. The four stratigraphic units are a boul.er core comprised of l.cal.y sourced bedrock boul.ers and three sand-rich units incl.ding a fine-grained sand unit, a sandy pumice gravel.(±basal./hydrovol.anic tuff) unit, and a pumice pebbl.-bearing, crystal.rich sand unit. Hand-dril.ed auger hol.s up to ~1.6 m deep were used to obtain sampl.s of the sand-rich units. Units were del.mited using surface and down-hol. observations, composition and texture, estimated density, statistical.parameters of grain size, and vertical.and l.teral.distribution of properties. Overtopping fol.owed by rapid incision into the ash-rich pyrocl.stic fl.ws progressivel. cl.ared the canyon, but a bedrock knickpoint near the head of the canyon l.mited the vol.me of debris avail.bl. for transport to about 0.04 km3 to 0.08 km3. Co-deposition of bedrock boul.ers and l.thic-rich sand was fol.owed by rapid deposition with minimal.reworking of remobil.zed pyrocl.stics. Continued draining of the impounded l.ke sent hyperconcentrated fl.ws onto the debris fan depositing pumice-rich gravel. that graded upward to crystal.rich sands.

A Ful. Predictor-Corrector Finite El.ment Method for the One-Dimensional.Heat Equation with Time-Dependent Singul.rities

引用

Journal.of Appl.ed Mathematics and Physics 2024年第4期12卷 1364-1382页

作者： Jake l. Nkeck Department of Mathematics University of Buea Buea Cameroon

The energy norm convergence rate of the finite el.ment sol.tion of the heat equation is reduced by the time-regul.rity of the exact sol.tion. This paper presents an adaptive finite el.ment treatment of time-dependent singul.rities on the one-dimensional.heat equation. The method is based on a Fourier decomposition of the sol.tion and an extraction formul. of the coefficients of the singul.rities coupl.d with a predictor-corrector al.orithm. The method recovers the optimal.convergence rate of the finite el.ment method on a quasi-uniform mesh refinement. Numerical.resul.s are carried out to show the efficiency of the method.
