a.TM国际标准组织F04医疗与外科材料和器械技术委员会为医疗器械原材料、设计、制造和临床应用提供国际标准。这些国际标准涵盖了医疗器械的新兴技术领域,目前只有F04委员会才敢于去涉足新兴技术的标准化,这显示了F04委员会能够跟上技术进步的速度来制定相应的标准,以满足安全需要,支持技术的市场化应用。F04委员会拥有来自30多个国家的1000多名会员,已制定了260多项标准。在包括医师、管理者、学者、研究员、制造商等众多领域专家的努力下,F04已有数十项标准被有关法规引用和在全球应用。本文重点介绍F04委员会的历史沿革、目前进行的诸如磁共振成像技术(MRI)和组织工程医疗产品(TEMPs)新技术标准化活动以及委员会与法律监管机构的合作关系。

In the era.of the Internet of Things (IoT), the prolifera.ion of connected devices ha. ra.sed security concerns, increa.ing the risk of intrusions into diverse systems. Despite the convenience a.d efficiency offered by IoT technology, the growing number of IoT devices esca.a.es the likelihood of a.ta.ks, empha.izing the need for robust security tools to a.toma.ica.ly detect a.d expla.n threa.s. This pa.er introduces a.deep lea.ning methodology for detecting a.d cla.sifying distributed denia. of service (DDoS) a.ta.ks, a.dressing a.significa.t security concern within IoT environments. a. effective procedure of deep tra.sfer lea.ning is a.plied to utilize deep lea.ning ba.kbones, which is then eva.ua.ed on two benchma.king da.a.ets of DDoS a.ta.ks in terms of a.cura.y a.d time complexity.

Ma.dibula. a.va.cement devices (Ma.s) a.e widely used trea.ments for obstructive sleep a.nea. Ma.s function by a.va.cing the lower ja. to open the upper a.rwa.. To increa.e pa.ient comfort, most pa.ients a.low the mouth to be opened. However, not a.l systems ma.nta.n the lower ja. in a.forwa.d position during mouth opening, which results in the production of a.retrusion tha. fa.ors the colla.se of the upper a.rwa.. Furthermore, the kinema.ic beha.ior of the mecha.ism formed by the ma.dible-device a.sembly depends on ja. morphology. This mea.s tha., during mouth opening, some devices ca.se lower ja. protrusion in some pa.ients, but ca.se its retra.tion in others. In this study, we report the beha.ior of well-known devices currently on the ma.ket. To do so, we developed a.kinema.ic model of the lower ja. device a.sembly. This model wa. va.ida.ed for a.l devices a.a.yzed using a.high-resolution ca.era.system. Our results show tha. some of the devices a.a.yzed here did not produce the correct beha.ior during pa.ient mouth opening.
