The impact of EAES Fellowship Programme:a five-year review and evaluation
No full textBackground: The European Association of Endoscopic Surgery (EAES) fellowship programme was established in 2014, allowing nine surgeons annually to obtain experience and skills in minimally invasive surgery (MIS) from specialist centres across the Europe and United States. It aligns with the strategic focus of EAES Education and Training Committee on enabling Learning Mobility opportunities. To assess the impact of the programme, a survey was conducted aiming to evaluate the experience and impact of the programme and receive feedback for improvements.Methods: A survey using a 5-point Likert scale was used to evaluate clinical, education and research experience. The impact on acquisition of new technical skills, change in clinical practice and ongoing collaboration with the host institute was assessed. The fellows selected between 2014 and 2018 were included. Ratings were analysed in percentage; thematic analysis was applied to the free-text feedbacks using qualitative analysis.Results: All the fellows had good access to observing in operating theatres and 70.6% were able to assist. 91.2% participated in educational activities and 23.5% were able to contribute through teaching. 44.1% participated in research activities and 41.2% became an author/co-author of a publication from the host. 97.1% of fellows stated that their operative competency had increased, 94.3% gained new surgical skills and 85.7% was able to introduce new techniques in their hospitals. 74.29% agreed that the clinical experience led to a change in their practices. The most commonly suggested improvements were setting realistic target in clinical and research areas, increasing fellowship duration, and maximising theatre assisting opportunities. Nevertheless, 100% of fellows would recommend the fellowship to their peers.Conclusion: EAES fellowship programme has shown a positive impact on acquiring and adopting new MIS techniques. To further refine the programme, an individualised approach should be adopted to set achievable learning objectives in clinical skills, education and research.</p
Investigation of Al-B<sub>4</sub>C Metal Matrix Composites Produced by Friction Stir Additive Processing
No full textAluminium—boron carbide metal matrix composites (Al-B4C MMCs) belong to the class of materials extensively used in the nuclear industry as a thermal neutron absorber in spent fuel casks. This article investigates a novel production method of Al-B4C MMCs—Friction Stir Additive Processing (FSAP)—as an alternative production method to casting or sintering. FSAP is derived from friction stir welding, which can be used to local modifications of microstructure, or it can be used to incorporate the second phase into the processed material. During this study, a variant of FSAP for MMC production was proposed, and its mechanical and thermal neutron absorbing properties have been investigated. Further, the influence of neutron irradiation on mechanical properties has been studied. Results show that FSAP can successfully produce Al-B4C MMCs with 7 mm thickness. Neutron irradiation causes only a slight increase in hardness, while its effect on tensile properties remains inconclusive
The laparoscopic surgical skills programme: Preliminary evaluation of grade I Level 1 courses by trainees
No full textIntroduction: New training models are needed to maintain safety and quality of surgical performance. A simulated setting using virtual reality, synthetic, and/or organic models should precede traditional supervised training in the operating room. Aim: The aim of the paper is to describe the Laparoscopic Surgical Skills (LSS) programme and to provide information about preliminary evaluation of Grade I Level 1 courses, including overall quality, applicability of the course content in practice and the balance between theory and hands-on training modules, by participating trainees. Material and methods: During 5 accredited LSS Grade I Level 1 courses held in Eindhoven (the Netherlands), Kosice (Slovak Republic), and Lisbon (Portugal) between April 2011 and January 2012, demographic data and pre-course surgical experience in laparoscopic surgery of the participants were recorded. The final course evaluation form was completed by each participant after the course (anonymous) to evaluate course progress, course materials, assessment, staff, location and overall impression of the course on a 1-10 scale to obtain feedback information. Results: Forty-seven surgeons of 5 different nationalities were enrolled in an LSS Grade I Level 1 programme. Most participants were first or second year residents (n = 25), but also already established surgeons took part (n = 6). The mean age of the participants was 31.2 years (SD = 2.86), the male/female ratio was 32/15, and previous experience with laparoscopic surgery was limited. Overall impression of the course was rated with 8.7 points (SD = 0.78). The applicability of the course content in practice and the balance between theory and hands-on training were also rated very well – mean 8.8 (SD = 1.01) and 8.1 points (SD = 0.80) respectively. Conclusions: Laparoscopic Surgical Skills Grade I Level 1 courses are evaluated as well balanced, with content applicable in clinical practice, meeting the expectations of individual participants. International interest in the programme suggests that LSS might become the future European standard in surgical education in laparoscopic surgery. Further conclusions concerning success of the programme may be drawn after the completion of clinical assessment of enrolled participants.Industrial DesignIndustrial Design Engineerin
Influence of the Environment on the Reliability of Security Magnetic Contacts
No full textMagnetic contacts are one of the basic components of an alarm system, providing access to buildings, especially windows and doors. From long-term reliability tests, it can be concluded that magnetic contacts show sufficient reliability. Due to global warming, we can measure high as well as low ambient temperatures in the vicinity of magnetic contacts, which can directly affect their reliability. As part of partial tests, research into the reliability of magnetic contacts, we created a test device with which their reaction distance was examined under extreme conditions simulated in a thermal chamber. The results of the practical tests have yielded surprising results
