Two-dimensional (2D) semiconductor materials with discrete bandgap become important because of their interesting physical properties and potentials toward future nanoscale electronics. Many 2D-based field effect transistors (FETs) have thus been reported. Several attempts to fabricate 2D complementary (CMOS) logic inverters made too. However, those CMOS devices seldom showed the most advantage typical CMOS: low power consumption. Here, we adopted p-WSe2 n-MoS2 nanosheets separately for...
We have fabricated dual gate field effect transistors (FETs) with 12 nm-thin black phosphorus (BP) channel on glass substrate, where our BP FETs a patterned-gate architecture 30 nm-thick Al2O3 dielectrics top and bottom of channel. Top dielectric has simultaneously been used as device encapsulation layer, controlling the threshold voltage well when mainly operate under bias. Bottom, top, gate-controlling mobilities were estimated to be 277, 92, 213 cm2/V s, respectively. Maximum ON-current...
As one of the emerging new transition‐metal dichalcogenides materials, molybdenum ditelluride (α‐MoTe 2 ) is attracting much attention due to its optical and electrical properties. This study fabricates all‐2D MoTe ‐based field effect transistors (FETs) on glass, using thin hexagonal boron nitride graphene in consideration good dielectric/channel interface source/drain contacts, respectively. Distinguished from previous works, this study, all 2D FETs with α‐MoTe nanoflakes are dual‐gated for...
Objective The learning curve–cumulative summation (LC-CUSUM) test allows for quantitative and individual assessments of the process. In this study, we evaluated process skill acquisition performing endotracheal intubation (ETI) in three emergency medicine (EM) residents over a 2 year period their first years EM residency. Methods We 342 ETI cases performed by using LC-CUSUM according to rate success or failure ETI. A 90% (SR) was chosen define adequate performance an SR 80% considered...
Background . Basic life support (BLS) training with hands-on practice can improve performance during simulated cardiac arrest, although the optimal duration for BLS is unknown. This study aimed to assess effectiveness of various durations acquiring cardiopulmonary resuscitation (CPR) and automated external defibrillator (AED) skills. Methods We randomised 485 South Korean nonmedical college students into four levels training: level 1 (40 min), 2 (80 3 (120 4 (180 min). Before after each...
Cardiopulmonary resuscitation (CPR) training can improve performance during simulated cardiac arrest; however, retention of skills after remains uncertain. Recently, hands-only CPR has been shown to be as effective conventional CPR. The purpose this study is compare the rate in laypersons or training.Participants were randomly assigned 1 2 methods: 80 minutes 180 training. Each participant's evaluated at end and 3 months thereafter using Resusci Anne manikin with a skill-reporting...
Students are largely providing feedback to one another when instructor facilitates peer rather than teaching in group training. The number of students a affect the learning We aimed investigate whether larger size increases students' test scores on post-training with facilitated by after video-guided basic life support (BLS) refresher Students' one-rescuer adult BLS skills were assessed 2-min checklist-based 1 year initial A cluster randomized controlled trial was conducted evaluate effect...
Chain of survival is a series steps required to increase the rate patients with cardiac arrest.To arrest, chain should be strengthened in community.Chain 2015 Korean cardiopulmonary resuscitation (CPR) guidelines composed five chains: prevention and immediate recognition early access (activation emergency medical system [EMS]), CPR, defibrillation, effective advanced life support post-cardiac arrest care (Fig. 1).
Summary Feedback devices have been shown to improve the quality of chest compression during cardiopulmonary resuscitation for patients in supine position, but no studies reported effects feedback on when is tilted. Basic life support‐trained providers were randomly assigned administer compressions a manikin supine, 30° left lateral tilt and semirecumbent positions, with or without aid device incorporated into smartphone. Thirty‐six participants studied. The did not affect improved aspects...
