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.

Input: Consider Input: Several studies have reported that ventriculoperitoneal shunt insertion for treatment of normal-pressure hydrocephalus results in improvement of gait and, less frequently, improvement of cognition. We sought to identify the demographic factors associated with cognitive improvement after shunt insertion to improve assessment of prognosis for cognitive gains with treatment.', 'We report cognitive testing before and after ventriculoperitoneal shunt insertion in 36 patients with normal pressure hydrocephalus, who previously had improvement of any clinical symptom--gait, urinary incontinence, cognition--after a diagnostic trial of continuous cerebrospinal fluid drainage.

Input: Consider Input: Perchlorate is an environmental contaminant that blocks iodine uptake into the thyroid gland and reduces thyroid hormones. This action of perchlorate raises significant concern over its effects on brain development.', 'The purpose of this study was to evaluate neurologic function in rats after developmental exposure to perchlorate.', 'Pregnant rats were exposed to 0, 30, 300, or 1,000 ppm perchlorate in drinking water from gestational day 6 until weaning. Adult male offspring were evaluated on a series of behavioral tasks and neurophysiologic measures of synaptic function in the hippocampus.', 'At the highest perchlorate dose, triiodothyronine (T(3)) and thyroxine (T(4)) were reduced in pups on postnatal day 21. T(4) in dams was reduced relative to controls by 16%, 28%, and 60% in the 30-, 300-, and 1,000-ppm dose groups, respectively. Reductions in T(4) were associated with increases in thyroid-stimulating hormone in the high-dose group. No changes were seen in serum T(3). Perchlorate did not impair motor activity, spatial learning, or fear conditioning. However, significant reductions in baseline synaptic transmission were observed in hippocampal field potentials at all dose levels. Reductions in inhibitory function were evident at 300 and 1,000 ppm, and augmentations in long-term potentiation were observed in the population spike measure at the highest dose.

Input: Consider Input: To evaluate the effect of 3-month kale (Brassica oleracea acephala) juice supplementation on coronary artery disease risk factors among hypercholesterolemic men.', 'Thirty-two men with hypercholesterolemia (> 200 mg/dL) were recruited after annual health examinations among the faculty and staff at university. The subjects consumed 150 mL of kale juice per day for a 12-week intervention period. Dietary and anthropometric assessments were performed and blood samples were collected to evaluate biochemical profiles before and after supplementation.', 'Serum concentrations of HDL-cholesterol, and HDL- to LDL-cholesterol ratio were significantly increased by 27% (P<0.0001) and 52% (P<0.0001), respectively. The LDL-cholesterol concentration and the atherogenic index were significantly reduced by 10% (P=0.0007) and 24.2% (P<0.0001), respectively without affecting body mass index, waist and hip circumferences, or nutrient intakes after three months of supplementation. While there was no difference in the concentration of malondialdehyde, significant increase in glutathione peroxidase activity (P=0.0005) were accompanied by a significant increase in the serum selenium level (P=0.0132). It was also found that the responses of these risk factors to kale juice administration were dependent on smoking status.
