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.

Example Input: To evaluate the effect of uterine leiomyomas on the endometrium using molecular markers of endometrial receptivity: HOXA10, HOXA11, LIF, and BTEB1.', 'Case-control study.', 'University medical center.', 'Thirty reproductive-aged women with submucosal, intramural, or no uterine myomas who underwent hysteroscopy or hysterectomy.', 'Proliferative phase endometrial sampling was performed at the time of surgery. In uteri with a submucosal myoma, directed endometrial biopsies were obtained over the myoma and over normal myometrium.', 'Endometrial HOXA10 expression was evaluated as a primary endpoint using quantitative real-time reverse transcriptase-polymerase chain reaction (RT-PCR) and immunohistochemistry. HOXA11, BTEB1, and LIF were evaluated using real-time RT-PCR.', 'Endometrial HOXA10 and HOXA11 messenger RNA (mRNA) expression were significantly decreased in uteri with submucosal myomas compared with controls and with uteri with intramural myomas. A similar trend was seen in BTEB1 mRNA expression; however, no difference was found in LIF mRNA expression. Immunohistochemistry localized the decrease in endometrial HOXA10 protein expression to stroma. In the presence of a submucosal myoma, there were no regional differences in gene expression.

Example Input: We conducted this study to analyze the values of the key cephalometric angular measurements of the mandible using 3-dimensional (3D) computed tomography scans.', 'In the 106 enrolled patients, a 3D cephalometric analysis was performed to measure the angular variables of the mandible. These values were compared between the two sides and between the two sexes.', 'The frontal measurements revealed that the mandibular body curve angle was larger on the left (Lt) side (right [Rt], 141.247.54; Lt, 142.686.94; P=0.002) and the gonial angle was larger on the right side (Rt, 134.378.44; Lt, 131.547.14; P<0.001). The sagittal measurements showed that the gonial angle was larger on the right side (Rt, 134.378.44; Lt, 131.547.14; P>0.05). Further, the transverse measurements revealed that the mandibular body curve angle was larger on the right side (Rt, 140.287.05; Lt, 137.566.23; P<0.001).

Example Input: The specific aim of the study was to investigate and compare epiphyseal length and extension in the proximal humerus, closure in the growth plate and bone marrow signal intensity related to the proximal humeral physis in the dominant arm and the non-dominant arm of the asymptomatic adolescent elite tennis player.', 'The study sample included 35 asymptomatic elite young tennis players (15 males and 20 females, mean age 17.4years2.7). Each player contributed with two shoulders to the MRI measurement. The non-dominant arm was used as a control.', 'Relative reliability between the radiologists was excellent (ICC 0.78-0.96). Statistically significant differences between dominant arm and non-dominant arm in epiphyseal length (mm) laterally (DA 27.3 vs NDA 26.7) were shown. Statistically significant differences were also found in epiphyseal extension (mm) laterally (DA 36.1 vs NDA 35.1) and ventrally (DA 36.2 vs NDA 34.8). No statistically significant differences were found between dominant arm and non-dominant arm in epiphyseal extension (mm) medially (DA 31.7 vs NDA 31.7) and dorsally (DA 22.6 vs NDA 22.1).
