Given a passage classify if the passage has a definite objective/aim/goal or not. Output '1' if the passage has a defininte objective/aim/goal and output '0' if the passage does not have a definite objective/aim/goal.

[Q]: Patients with acute myocardial infarction (AMI) whose culprit lesion lies in a branch of the 3 major coronary arteries have well-preserved cardiac function. A first MI with preserved cardiac function is a risk factor for left ventricular free wall rupture (LVFWR), so the aim of this study was to investigate the possible relationship between AMI with branch segment occlusion and LVFWR.', 'The 439 patients with AMI were retrospectively studied. They were divided into 2 groups: group B (n=70; segments 4 atrioventricular node artery, 4 posterior descending coronary artery, 8, 9, 10, 12, 14, or 15 according to the AHA classification), and group P (n=369; segments 1, 2, 3, 5, 6, 7, 11, or 13). Primary percutaneous coronary intervention (PCI) was more often performed in group P (75% vs 57%; P=0.0018). In-hospital mortality tended to be lower in group B (1.4% vs 6.2%; P=0.105). The incidence of LVFWR was significantly higher in group B (10.0% vs 1.6%; P=0.0002).By multivariate logistic regression analysis, 1-vessel disease, absence of primary PCI, branch segment occlusion, and age were identified as independent predictors of LVFWR.

[Q]: To determine whether full-scale simulation (SIM) is superior to interactive problem-based learning (PBL) for teaching medical students acute care assessment and management skills.', 'Randomized controlled trial.', 'Simulation center at a U.S. medical school.', 'Thirty-one fourth-year medical students in a week-long acute care course.', 'After institutional review board approval and informed consent, eligible students were randomized to either the SIM or PBL group. On day 1, all subjects underwent a simulator-based initial assessment designed to evaluate their critical care skills. Two blinded investigators assessed each student using a standardized checklist. Subsequently, the PBL group learned about dyspnea in a standard PBL format. The SIM group learned about dyspnea using the simulator. To equalize simulator education time, the PBL group learned about acute abdominal pain on the simulator, whereas the SIM group used the PBL format. On day 5, each student was tested on a unique dyspnea scenario.', "Mean initial assessment and final assessment checklist scores and their change for the SIM and PBL groups were compared using the Student's t-test. A p < .05 was considered significant. The SIM and PBL groups had similar mean (PBL 0.44, SIM 0.47, p = .64) initial assessment scores (earned score divided by maximum score) and were deemed equivalent. The SIM group performed better than the PBL group on the final assessment (mean, PBL 0.53, SIM 0.72, p < .0001). When each student's change in score (percent correct on final assessment minus percent correct on the initial assessment) was compared, SIM group students performed better (mean improvement, SIM 25 percentage points vs. PBL 8 percentage points, p < .04)

[Q]: To assess the effects of soft contact lens base curve radius (BCR), sex, ethnicity, central corneal curvatures, and vertical palpebral aperture size (PAS) on the postlens tear thickness (PLTT).', 'The PLTT was measured using optical pachometry on 114 experienced lens wearers who were fitted with lathe-cut soft lenses (Alden 47, polymacon, 35.5% H2O, -2.00 diopter, and 14.0 mm). Each subject was randomly allocated to one lens group receiving a BCR of 7.9, 8.3, or 8.7 mm. Pachometry measurements were taken at 30 min after lens insertion. Vertical PAS and keratometry readings were measured for 94 of the 114 subjects.', 'The mean (95% confidence interval) PLTT was 15.7 microm (13.2-18.0 microm), 12.8 microm (10.9-14.7 microm), and 12.1 microm (10.2-14.0 microm) for the 7.9-mm, 8.3-mm, and 8.7-mm BCR groups, respectively. The differences in PLTT among the three BCR groups was significant (analysis of variance F-test; P=0.039). Post hoc testing using the Tukey honestly significant difference statistic showed that only the two extreme BCR groups (7.9 mm and 8.7 mm) were significantly different. Sex had no effect on the PLTT; however, the PLTT was significantly thinner for the Asian compared with non-Asian eyes (P=0.0001). The Asian PLTT did not vary with different soft lens BCRs. The non-Asian PLTT was thicker with lenses of the steep BCR compared with the flat BCR.
