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: Our objective was to identify the antioxidant properties of honeybee products from Turkey, chestnut honey, pollen, propolis, and royal jelly, and their hepatoprotective activity against CCl4-induced hepatic damage in rats.', 'Animals were fed with honeybee products for 7 days following CCl4 injection. Development of liver damage and oxidative stress were monitored by measuring the activities of the enzymes alanine transaminase, aspartate transaminase, malondialdehyde, superoxide dismutase, and catalase. Antioxidant capacities of the bee products were identified using FRAP and DPPH assays, as well as by measuring total phenolic and flavonoid contents.', 'The antioxidant activities of the honeybee products were highest in propolis, followed, in order, by pollen, honey, and royal jelly. Despite their different levels of antioxidant capacity, their roles in the prevention of liver damage induced by CCl4 were very similar, which can be explained through their bioavailability to the treated animals.

Example Input: Evidence regarding the mortality rate after administration of the pandemic influenza A (H1N1) 2009 vaccine on patients with underlying diseases is currently scarce. We conducted a case-control study in Japan to compare the mortality rates of patients with idiopathic interstitial pneumonia after the vaccines were administered and were not administered.', 'Between October 2009 and March 2010, we collected clinical records in Japan and conducted a 1:1 matched case-control study. Patients with idiopathic interstitial pneumonia who died during this period were considered case patients, and those who survived were considered control patients. We determined and compared the proportion of each group that received the pandemic influenza A (H1N1) 2009 vaccine and estimated the odds ratio. Finally, we conducted simulations that compensated for the shortcomings of the study associated with adjusted severity of idiopathic interstitial pneumonia.', 'The case and control groups each comprised of 75 patients with idiopathic interstitial pneumonia. The proportion of patients who received the pandemic influenza A (H1N1) 2009 vaccine was 30.7% and 38.7% for the case and control groups, respectively. During that winter, the crude conditional odds ratio of mortality was 0.63 (95% confidence interval, 0.25-1.47) and the adjusted conditional odds ratio was 1.18 (95% confidence interval, 0.33-4.49); neither was significant. The simulation study showed more accurate conditional odds ratios of 0.63-0.71.

Example Input: Closed suction drains have an important role in surgical wound healing. Although most surgeons use them routinely, indications for use and their postoperative management (emptying, removal) vary. The purpose of this study was to assess drain use by head and neck surgeons in Canada, to conduct a biomechanical analysis of the drains in a laboratory setting, and to make recommendations for drain use and management.', 'A survey was mailed to 343 active members of the Canadian Society of Otolaryngology. Three sets of experimental trials were conducted on the most commonly used drains to assess the effect of increased reservoir filling on suction generated through (1) incrementally increasing the amount of fluid within the reservoir, (2) compression of the reservoir with no fluid within, and (3) compression with the reservoirs while filled to 25% capacity with fluid.', 'A 41% response rate was obtained. It was found that the majority of head and neck surgeons in Canada use Hemovac and Jackson-Pratt drainage systems routinely. There is considerable variability in practice with regard to drain emptying and timing of removal. Experimental results indicate that as filling of the reservoir increases, suction generated decreases sharply, to between 13 and 20% of initial values at 50% capacity.
