Background. The equality of subjective- and objective-assessment methods in laparoscopic surgery are unknown. The aim of this study was to compare a subjective assessment method to an objective assessment method to evaluate laparoscopic skill. Methods. A prospective observational cohort study was conducted. Seventy-two residents completed a basic laparoscopic suturing task on a box trainer at two consecutive assessment points. Laparoscopic skill was rated subjectively using the Objective Structured Assessment of Technical Skills (OSATS) list and objectively using the TrEndo, an augmented-reality simulator. Results. TrEndo scores between the two assessment points correlated. OSATS scores did not correlate between the two assessment points. There was a correlation between TrEndo and OSATS scores at the first assessment point, but not at the second assessment point. Overall, OSATS scores correlated with TrEndo scores. There was a greater spread within OSATS scores compared to TrEndo scores. Conclusion. OSATS scores correlated with TrEndo scores. The TrEndo may be more responsive at rating individual’s laparoscopic skill, as demonstrated by a smaller overall spread in TrEndo scores. The additional value of objective assessment methods over conventional assessment methods as provided by laparoscopic simulators should be investigated.

History Of

Unmasking aircraft pilot couplings (APCs) prior to vehicle entry into service have been a long standing challenge in the aerospace industry. APCs, often only exposed through unpredictable or very specific circumstances, have arisen throughout the history of manned powered flight and have required stopgap “fixes” to ensure system safety once a problem has been identified. This paper describes two newly created novel tools, one objective and one subjective, to detect and analyze APCs. The Phase Aggression Criterion is the objective assessment method and, in the advanced form described in this paper, is capable of APC detection in near real time. The innovative Adverse Pilot Coupling Scale is a subjective assessment method for APCs experienced during completion of closed-loop tasks. Results from the application of both of these tools are presented as well as the very good correlation between them. Furthermore, the application of the tools to simulated flight-test data has shown how existing handling qualities mission task element courses and their associated performance tolerances can be inadequate when used to unmask the proneness of a pilot–vehicle system to APC.

English testing is a most common test conducted around the world for evaluating an individual’s English capabilities in mostly reading, writing, speaking, and listening domain. With increased cost and higher subjective assessment attached in some tests, there is required to change the test from traditional method to computer based. In this study, a proposed method for conducting speaking test for English based on objective assessment method. The proposed system is able to identify different dialects based on unit analysis of syllable along with phonetic errors. The proposed system is based on pronunciation parameters and neural network for evaluation purpose. The PSO algorithm is used for training the artificial neural network. The experiment result conducted for validating the proposed system shows promising performance

Abstract. Background: Arterial surgery for lower limb ischaemia is a frequently performed procedure in patients with severe cardio-pulmonary comorbidities, making them high-risk patients for acute postoperative complications with a need for prolonged stay in the post-anaesthesia care unit (PACU). However, detailed information on complications during the PACU stay is limited, hindering mechanism-based interventions for early enhanced recovery. Thus, we aimed to systematically describe acute complications and related risk factors in the immediate postoperative phase after infrainguinal arterial surgery. Patients and methods: Patients transferred to the PACU after infrainguinal arterial surgery due to chronic or acute lower limb ischaemia were consecutively included in a six-month observational cohort study. Pre- and intraoperative data included comorbidities as well as surgical and anaesthetic technique. Data on complications and treatments in the PACU were collected every 15 minutes using a standardised assessment tool. The primary endpoint was occurrence of predefined moderate or severe complications occurring during PACU stay. Results: In total, 155 patients were included for analysis. Eighty (52 %) patients experienced episodes with oxygen desaturation (< 85 %) and moderate or severe pain occurred in 72 patients (47 %); however, circulatory complications (hypotension, tachycardia) were rare. Preoperative opioid use was a significant risk factor for moderate or severe pain in PACU (59 vs. 38 % chronic vs. opioid naïve patients (P = 0.01). Conclusions: Complications in the PACU after infrainguinal arterial surgery relates to saturation and pain, suggesting that future efforts should focus on anaesthesia and analgesic techniques including opioid sparing regimes to enhance early postoperative recovery.
