Intercloud is a federated environment of private clusters and public clouds. The performance of Hadoop could be degraded significantly in intercloud environments. Because previous solutions for intercloud environments rely on speculative execution, they require additional cost in the cloud. In this paper, we propose a new task scheduler that improves performance without the help of speculative execution in intercloud environments.

[Purpose] The purpose of this study was to investigate the effect of jaw opening exercise (JOE) on aspiration in patients with dysphagia after stroke. [Subjects and Methods] Three subjects were recruited. Isometric and isotonic JOE were performed using a rubber ball, 5 days a week for 4 weeks. Aspiration was evaluated using the penetration-a spiration scale (PAS) based on a videofluoroscopic swallowing study. [Results] All subjects showed a score reduction of at least 1 point and a maximum reduction of 2 points in the PAS in the liquid type. [Conclusion] This study confirmed that JOE can be used to reduce aspiration in patients with dysphagia after stroke.

Purpose: The purpose of this study was to investigate the factors that make the bathroom experience an inconvenient one for stroke patients, including the use of basic materials to provide an effective and individualized bathroom environment. Result:The degree of inconvenience of bathroom usage results showed that the group of patients using wheelchairs experience more inconvenience than the group of patients without wheelchairs. The inconvenient factors between two groups are shown to have significant differences in the door sill, the location of the mirror, the chair for showering, transferring to the bathtub, slippery floor, the location of cabinets, door width, shower space, the location of shower booth, and the safety handle on the wall and toilet (p<.05). Conclusion:The result of this research shows that the inconvenient factors in the bathroom experience stroke patients vary depending on the use of wheelchair. The result may be utilized as therapeutic basic materials provide an effective bathroom environment to stoke patients in future.
