Diphenylhydantoin 투여중 발생한 순수 적혈구 형성 부전증 : 증례 보고 Case Report
장진우,박종운,이종화,김영수 대한신경외과학회 1987 Journal of Korean neurosurgical society Vol.16 No.1
The authors have described a case with pure red cell aplasia (P.R.C.A.) caused by the administration of diphenylhydantoin after head injury. P.R.C.A. associated with diphenylhydantoin is very rare and easily treated with a discontinuation of diphenylhydantoin & steroids.
Energy-aware Task Scheduling for Multi-Processor Systems considering Battery Lifetime
Il-jong Jung,Jong-wha Chong 대한전자공학회 2008 ITC-CSCC :International Technical Conference on Ci Vol.2008 No.7
Increasing needs of large-scale tasks, using single processor in a system is inefficient because it causes waste of energy consumption due to high operating frequency. To overcome the defect of a single processor, multi-processor systems which can operate tasks on low frequency are required to minimize energy consumption. Since the multiprocessor systems are expanded to portable devices such like PDAs, laptop computers and cellular phones, it is necessary to not only minimize energy consumption but also optimize battery lifetime because these devices are powered by batteries. This paper presents two solutions to maximize the portable device lifetime. First, the tasks are partitioned to subtasks have the different operating frequencies, which are higher than the previous subtask in a task. The operating frequencies and the subtasks’ execution cycles are decided by the formulation to guarantee the deadlines and the energy efficiency. This method maximizes the energy reduction because the latter subtasks operated by the higher frequency are not executed if tasks’ execution cycles are decreased. To minimize the average energy consumption, the tasks’ execution times are extended to the deadlines to lower the operating frequencies. Second, the frequencies of tasks scheduled in processors are adjusted by Dynamic Voltage Scaling (DVS) to avoid that the maximum frequency of each task overlaps. This process optimizes the battery lifetime, satisfying recovery effect. The simulation results show that the proposed method saves 15%~50% more energy than the existing method.
