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: The aim of this study was to evaluate and compare microwave disinfection with chemical disinfection of dental gypsum casts.', 'A total of 120 casts were prepared from a silicone mold using Type III dental stone. Of the 120 casts, 60 casts were contaminated with 1 ml suspension of Staphylococcus aureus and 60 casts were contaminated with 1 ml suspension of Pseudomonas aeruginosa. Then, the casts were disinfected with microwave irradiation and chemical disinfection using the microwave oven and 0.5% sodium hypochlorite. Bacteriologic procedures were performed; the cfu/ml for each cast was calculated as a weighted mean. The results were analyzed using Kruskal-Wallis test and Mann-Whitney test.', 'The untreated casts showed Brain heart infusion broth counts of 106 log cfu/ml compared to irradiated and chemically disinfected casts, in which 105 log reduction of cfu/ml was seen. These results satisfied the requirements of current infection control guidelines for the dental laboratory. The results obtained for chemical disinfection were in equivalence with microwave disinfection.

Example Input: To investigate the relationship between the damages of hand functions and the type of cerebral palsy (CP) in children with CP.', 'A total of 280 children aged 4-12 years old with CP in the 20 districts of Chengdu were included. The damages of hand functions were assessed with the Chinese Version of Manual Ability Classification System (MACS) and its relationship with the type of CP were analyzed.', 'Among the 280 investigated children, there were 195 chidren with spastic CP, which accounted for the largest proportion (69.64%), wherein the spastic diplegia was most common (56.41%). The classification of MACS was level I-II in 65.13% children with spastic CP, whereas the classification of MACS was level IU-V in 84. 44% and 80.95% children with mixed and dyskinetic CP, respectively. With the increase of the degree of cognitive dysfunction in children with CP, the level of MACS was also increased. There was a difference between the classification of MACS and the different type of CP (P<0.05). The children with spastic CP were mostly mild hand dysfunction, while the children with mixed and dyskinetic type of CP were mostly middle and severe hand dysfunction. A positive correlation was found between the MACS and the subtype of spastic CP (r=0.541, P<0.05). In most of the children with diplegia from spastic CP, the hand dysfunction was mild, whereas the children with quadriplegia from spastic CP were mostly middle and severe hand dysfunction.

Example Input: Adenosine administered intravenously terminates supraventricular tachycardias (SVT) involving the AV node as part of the reentrant circuit. Dipyridamole increases interstitial myocardial levels of this nucleoside. This study was designed to determine whether intravenous dipyridamole increases coronary sinus plasma adenosine concentrations ([Ado]cs) in humans to levels sufficient to alter electrophysiological parameters and terminate SVT.', 'A custom-designed catheter and syringe for sampling blood for measurement of [Ado]cs was placed in the coronary sinuses of 7 patients. [Ado]cs and refractory periods and conduction characteristics of the atrium and AV node were determined after autonomic blockade and dipyridamole infusion (5 micrograms.kg-1.min-1 after a loading dose of 0.56 mg/kg). The atrial effective and functional refractory periods remained unchanged after dipyridamole infusion. In contrast, the AV nodal functional refractory period increased from 350 +/- 32 to 381 +/- 41 milliseconds (P = .03); the Wenckebach cycle length also increased from 309 +/- 47 to 350 +/- 57 milliseconds (P < .0001). Coincident with these changes, [ADO]cs increased from 0.18 +/- 0.11 to 0.31 +/- 0.12 mumol/L (P = .02). In another 10 patients with AV or AV nodal reentrant tachycardia, SVT was induced, and coronary sinus blood samples were drawn. Dipyridamole was infused, and coronary sinus blood samples were obtained after 15 minutes or coincident with termination of SVT. Mean [ADO]cs increased from 0.17 +/- 0.06 mumol/L during SVT to 0.38 +/- 0.21 mumol/L after dipyridamole (P = .02). Mean tachycardia cycle length increased from 334 +/- 132 to 375 +/- 139 milliseconds (P = .02); this effect was confined to the AV node, as demonstrated by an increase in AH interval from 171 +/- 144 to 214 +/- 140 milliseconds (P = .003). SVT terminated with the infusion of dipyridamole in 4 of the 10 patients.
