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 compare silica gel with acyclovir cream in the treatment of recurrent herpes labialis.', 'In this randomized, open-label, comparator-controlled trial, 74 patients with recurrent herpes labialis applied silica gel or acyclovir cream respectively over a period of 10 days. The treatment started within 24 hours of the first symptoms of a new recurrence. Patients rated five symptoms (tautness, tingling, itching, burning sensation, pain), lesion stage, efficacy, tolerability, and duration until the onset of improvement. Their willingness-to-pay was assessed. Physicians rated the severity of the herpes recurrence and efficacy.', "There was no significant difference between silica gel and acyclovir cream in the overall patients' assessment. There is evidence that silica gel relieved all investigated symptoms earlier than acyclovir cream. The efficacy and tolerability of both medications were rated as good to very good.

Example Input: To determine whether systemically administered recombinant human epidermal growth factor (rhEGF) accelerates the recovery of mouse small intestinal mucosa after irradiation.', 'A mouse mucosal damage model was established by administering radiation to male BALB/c mice with a single dose of 15 Gy applied to the abdomen. After irradiation, rhEGF was administered subcutaneously at various doses (0.04, 0.2, 1.0, and 5.0 mg/kg/day) eight times at 2- to 3-day intervals. The evaluation methods included histologic changes of small intestinal mucosa, change in body weight, frequency of diarrhea, and survival rate.', 'The recovery of small intestinal mucosa after irradiation was significantly improved in the mice treated with a high dose of rhEGF. In the mice that underwent irradiation without rhEGF treatment, intestinal mucosal ulceration, mucosal layer damage, and severe inflammation occurred. The regeneration of villi was noticeable in mice treated with more than 0.2 mg/kg rhEGF, and the villi recovered fully in mice given more than 1 mg/kg rhEGF. The frequency of diarrhea persisting for more than 3 days was significantly greater in the radiation control group than in the rhEGF-treated groups.

Example Input: We compared conventional treatment with pumpless extracorporeal lung membrane (Interventional Lung Assist [iLA] Novalung; Novalung GmbH, Hechingen, Germany) support in a pig model of postpneumonectomy severe acute respiratory distress syndrome.', 'Adult pigs underwent a left thoracotomy without (group I) or with a left extrapericardial pneumonectomy and radical lymphadenectomy (groups II to V). After stabilization, pigs belonging to group II were observed only, whereas in those belonging to groups III to V, a surfactant-depletion severe (Pao(2)/Fio(2) < 100) postpneumonectomy acute respiratory distress syndrome was induced. This was followed by observation (group III); treatment with conventional therapy including protective ventilation, steroids, and nitric oxide (group IV); or femoral arteriovenous iLA Novalung placement, near-static ventilation, steroids, and nitric oxide (group V). Each group included 5 animals. Primary outcome was extubation 12 hours postoperatively or postpneumonectomy acute respiratory distress syndrome.', 'A severe postpneumonectomy acute respiratory distress syndrome was obtained after 9 +/- 2 alveolar lavages over 90 +/- 20 minutes. In group V pigs, the iLA Novalung device diverted 17% +/- 4% of the cardiac output, permitted an oxygen transfer and carbon dioxide removal of 298.4 +/- 173.7 mL/min and 287.7 +/- 87.3 mL/min, respectively, and static ventilation (tidal volume, 2.2 +/- 1 mL/kg; respiratory rate, 6 +/- 2.9 breaths/min). All but 1 pig belonging to group V could be extubated compared with none in groups III and IV (P < .01), and only their lungs normalized cytokine release (P < .001) and surfactant (P < .03) and displayed fewer parenchymal lesions (P < .05).
