Control manual para CNC

El objetivo del proyecto es diseñar un control manual para controlar un CNC (Control Numérico por Computadora) de forma no automática. A lo largo del proyecto en primer lugar se estudiará la tarjeta HY-TB4DV-M obteniendo sus esquemas mediante ingeniería inversa para diseñar de la manera más apropiada el Control Manual aquí descrito. En segundo lugar se realizará el diseño y fabricación del prototipo para la posterior comprobación de su correcto funcionamiento. En tercer lugar se procederá a programar el prototipo mediante la plataforma Arduino dotando al proyecto de las funcionalidades y características deseadas. Por último se hará el diseño final del Control Manual para CNC a partir del prototipo optimizando las características que hayan ofrecido margen de mejora. La finalidad última de este proyecto es la fabricación y comercialización del diseño para el usuario final que desee un control manual fácil de usar e intuitivo.Departamento de Tecnología ElectrónicaIngeniero Técnico de Telecomunicación, Especialidad en Sistemas Electrónico

Global attitudes in the management of acute appendicitis during COVID-19 pandemic: ACIE Appy Study

Background: Surgical strategies are being adapted to face the COVID-19 pandemic. Recommendations on the management of acute appendicitis have been based on expert opinion, but very little evidence is available. This study addressed that dearth with a snapshot of worldwide approaches to appendicitis. Methods: The Association of Italian Surgeons in Europe designed an online survey to assess the current attitude of surgeons globally regarding the management of patients with acute appendicitis during the pandemic. Questions were divided into baseline information, hospital organization and screening, personal protective equipment, management and surgical approach, and patient presentation before versus during the pandemic. Results: Of 744 answers, 709 (from 66 countries) were complete and were included in the analysis. Most hospitals were treating both patients with and those without COVID. There was variation in screening indications and modality used, with chest X-ray plus molecular testing (PCR) being the commonest (19\ub78 per cent). Conservative management of complicated and uncomplicated appendicitis was used by 6\ub76 and 2\ub74 per cent respectively before, but 23\ub77 and 5\ub73 per cent, during the pandemic (both P < 0\ub7001). One-third changed their approach from laparoscopic to open surgery owing to the popular (but evidence-lacking) advice from expert groups during the initial phase of the pandemic. No agreement on how to filter surgical smoke plume during laparoscopy was identified. There was an overall reduction in the number of patients admitted with appendicitis and one-third felt that patients who did present had more severe appendicitis than they usually observe. Conclusion: Conservative management of mild appendicitis has been possible during the pandemic. The fact that some surgeons switched to open appendicectomy may reflect the poor guidelines that emanated in the early phase of SARS-CoV-2
