The effectiveness of the Escape Room as an educational methodology in the Infarction Code.

OBJECTIVE: To evaluate the efficacy of an educational intervention (escape room) in the acquisition and retention of knowledge in relation to the Infarction Code, and to compare the knowledge of other teaching methodologies related to the Infarction Code. METHODS: A pre-post study was designed without a control group. After one month of the master class on the Infarction Code given to master's degree (doctors and nurses), an educational intervention was carried out consisting of an Escape Room on the same content, with a questionnaire that collected various sociodemographic data, and a knowledge test on the Infarction Code, which was repeated immediately after the activity and at the end of 2 months after the activity, and a test of knowledge on the Infarction Code. immediately after the activity and 2 months after the master class. Likewise, after the activity, a gamified experience evaluation questionnaire (GAMEX) was completed. RESULTS: Thirty-two students received the educational intervention (12 physicians and 20 nurses), and differences were observed between medical and nursing professionals in terms of initial knowledge of simulation and gamification. After the activity, and based on the initial knowledge test, the score increased by 3.49 points, an increase that was also reflected in the test taken two months after the master class, where an increase of 2.08 points was maintained. The participants rated the experience positively, with no significant overall differences between the two professional groups. CONCLUSIONS: The nurses had greater knowledge and contact with clinical simulation, virtual reality and gamification. The escape room showed to be a valid method for the assimilation and retention of knowledge in master's degree students. Medical professionals experienced a greater degree of immersion in the activity.

Laser Annealing of P and Al Implanted 4H-SiC Epitaxial Layers.

This work describes the development of a new method for ion implantation induced crystal damage recovery using multiple XeCl (308 nm) laser pulses with a duration of 30 ns. Experimental activity was carried on single phosphorus (P) as well as double phosphorus and aluminum (Al) implanted 4H-SiC epitaxial layers. Samples were then characterized through micro-Raman spectroscopy, Photoluminescence (PL) and Transmission Electron Microscopy (TEM) and results were compared with those coming from P implanted thermally annealed samples at 1650-1700-1750 °C for 1 h as well as P and Al implanted samples annealed at 1650 °C for 30 min. The activity outcome shows that laser annealing allows to achieve full crystal recovery in the energy density range between 0.50 and 0.60 J/cm2. Moreover, laser treated crystal shows an almost stress-free lattice with respect to thermally annealed samples that are characterized by high point and extended defects concentration. Laser annealing process, instead, allows to strongly reduce carbon vacancy (VC) concentration in the implanted area and to avoid intra-bandgap carrier recombination centres. Implanted area was almost preserved, except for some surface oxidation processes due to oxygen leakage inside the testing chamber. However, the results of this experimental activity gives way to laser annealing process viability for damage recovery and dopant activation inside the implanted area.
