Improvement of The Driver Simulator Control and Comparison Between Driver-Road-Vehicle Interaction in Real and Simulated Environment

The present doctoral thesis discusses the ways to improve the performance of driving simulator, provide objective measures for the road safety evaluation methodology based on driver’s behavior and response and investigates the drivers' adaptation to the driving assistant systems. The activities are divided into two macro areas; the driving simulation studies and on-road experiments. During the driving simulation experimentation, the classical motion cueing algorithm with logarithmic scale was implemented in the 2DOF motion cueing simulator and the motion cues were found desirable by the participants. In addition, it found out that motion stimuli could change the behaviour of the drivers in terms of depth/distance perception. During the on-road experimentations, The driver gaze behaviour was investigated to find the objective measures on the visibility of the road signs and reaction time of the drivers. The sensor infusion and the vehicle monitoring instruments were found useful for an objective assessment of the pavement condition and the drivers’ performance. In the last chapter of the thesis, the safety assessment during the use of level 1 automated driving “ACC” is discussed with the simulator and on-road experiment. The drivers’ visual behaviour was investigated in both studies with innovative classification method to find the epochs of the distraction of the drivers. The behavioural adaptation to ACC showed that drivers may divert their attention away from the driving task to engage in secondary, non-driving-related tasks.

Surgery after biological therapy in locally advanced NSCLC with molecular driver: feasibility and effectiveness of a new multidisciplinary approach

Introduction: Surgical outcomes after biological therapy have not been investigated yet and no information about timing, postoperative complications and survival have been recorded. Methods: This is a prospective study which compares a group of stage IIIA and IIIB NSCLC patients treated with biological therapy with patients undergoing standard induction chemotherapy. Data reported are preliminary results on the safety and effectiveness of surgery after target therapy. Results: We compared 22 patients treated with standard chemotherapy (Group 1) and 6 patients who received target therapy (Group 2). No differences were observed with an important bias due to the limited number of cases. The median time of resection was 159.8 ± 62.8 for group 1 and 201 ± 57.8 for group 2 (p=0.194). Complete resection was obtained in all Group 1-cases. Post-operative complication rate was 22% vs 16% (p=1). Pathologists reported necrosis >50% in 13% in group 1, Fibrosis >50% was presents respectively in 27% and 33% of patients (p=1). Residual vital tumor was >50% in 77% of patients undergone CT and in 66% of patients undergone TT (p=0.622). A total of 6 (31%) patients in the CT-group developed recurrence, 3 in the TT- group (64.2%), p was 0.634. No difference was observed both in terms of OS (P=0.29, Figure 3) and in term of DFS (P=0.106, Figure 4). Discussion: There is no consensus in the use of target therapy for advanced tumor in association with surgery. EGFR-tyrosine kinase inhibitors showed higher and more rapid response and our study wants to demonstrate that surgery after target therapy gives full access to the advantage of definitive local treatment. In our series, despite fibrosis, radical surgery has been achieved in all patients operated. The intraoperative blood loss, operation time, postoperative hospital stay and postoperative complication rate seems to be similar.
