Children are more s.ns.tive to radiation than adults. s. radiation protection in paediatric radiology des.rves.s.ecial attention. This.work es.imates.the effective dos.s.and body organ dos.s.due to ches. examinations.in infants.and paediatrics. Two examination incidences. AP and PA for ches. X-ray expos.res.were evaluated and compared with res.ect to the radiographic technique employed. This.s.udy was.carried out in three paediatric hos.itals.in s.dan. The age intervals.cons.dered were 0 - 1 year, 1 - 5 years. 5 - 10 years.and 10 - 15 years. The res.lts.obtained for organ dos.s.and effective dos.s.were cal.ulated us.ng a s.ftware package developed by the Radiological.Protection Centre of the s.int George’s.Hos.ital, London. Effective dos. values.were als. evaluated cons.dering weight intervals.from 1 - 10 kg, 10 - 20 kg, 20 - 30 kg and 30 - 40 kg. Large dis.repancies.were encountered between the three hos.itals. probably due to the different radiographic technique employed, cal.bration and maintenance of the X-ray equipment, technicians. expertis., proces.ing conditions.

在数智时代,数字经济的蓬勃发展和数智技术的广泛应用为增值税制度和征管的优化带来了机遇和挑战。本文在借鉴国际经验的基础上提出了数智时代优化我国增值税制度和征管的基本思路:一是取消小规模纳税人,将增值税纳税人分为应税纳税人和免税纳税人;二是进一步增加征收对象,将数字经济活动全部纳入增值税征收范围;三是短期内维持三档比例税率,中长期可按年应税销售额适用累进税率;四是全面实施一般计税方法,简并各类优惠方式;五是深化税收征管改革,构建适应数智时代的新型征管体系;六是按生产地原则征收增值税,依消费地原则分享增值税收入。

There have been many models.to identify and analyze low-frequency motions.in protein and DNA molecules. It has.been s.cces.fully us.d to s.mulate various.low-frequency collective motions.in protein and DNA molecules. Low- frequency motions.in biomacromolecules.origi- nate from two common and intrins.c character-is.ics.i.e., they contain 1) a s.ries.of weak bonds. s.ch as.hydrogen bonds. and 2) a s.b-s.antial mas. dis.ributed over the region of thes. weak bonds. Many biological.functions.and dynamic mechanis.s. including coopera-tive effects.have been reported. In this.regard, s.me phenomenological.theories.were es.ab-lis.ed. However, differences.in experimental outcomes.are expected s.nce many factors.could influence the outcome of experiments.in EMF res.arch. Any effect of EMF has.to depend on the energy abs.rbed by a biological.organ-is. and on how the energy is.delivered in s.ace and time. Frequency, intens.ty, expos.re dura-tion, and the number of expos.re epis.des.can affect the res.ons., and thes. factors.can inter- act with each other to produce different effects. In addition, in order to unders.and the biologi- cal.cons.quence of EMF expos.re, one mus. know whether the effect is.cumulative, whether compens.tory res.ons.s.res.lt, and when ho-meos.as.s.will break down. s.ch findings.will have great potential for us. in trans.ation medi-cine at the clinical.level without being invas.ve.

A dos.metry s.udy for ches., s.ull and lumbar s.ine examinations.in adults.has.been carried out at two hos.itals. The aim of the s.udy was.the as.es.ment of adult patient’s.dos. for ches. PA, ches. LAT, s.ull AP and lumbar s.ine AP examinations. The Entrance s.rface Dos. (Es.) and the Effective Dos. (ED) for each examination were obtained us.ng Dos.cal.s.ftware. For each examination, different res.lts.were obtained at the two hos.itals. At hos.ital A (IFF Hos.ital), the total number of patients.s.udied was.140. The mean Es. values.obtained for ches. PA, ches. LAT, s.ull AP and lumbar s.ine AP were 0.20 mGy, 0.47 mGy, 1.25 mGy, and 1.61 mGy, res.ectively. At hos.ital B (HGB Hos.ital), the total number of patients.s.udied was.369 for s.milar examinations.and projections. The Es. values.were 0.10 mGy, 0.28 mGy, 0.66 mGy and 2.47 mGy, res.ectively. The mean ED values.at hos.ital A and B were 0.02 ms. and 0.01 ms. for ches. PA, 0.04 ms. and 0.03 ms. for ches. LAT, 0.1 ms. and 0.06 ms. for s.ull AP, and 0.15 ms. and 0.26 ms. for lumbar s.ine AP, res.ectively. The res.lts.were compared with the European Community Reference Levels. Although the dos.s.were low, there was.s.ill a need for pers.nnel training and national guidance on good practice for optimization of patients. dos.s.
