Objective : The purpose of this case study is to report the effectiveness of Sojongyuryang-tang gagambang in respect of spleen dampness on 3 psoriasis patients who had unhealthy dietary habit.Methods : PASI(psoriasis area and severity) score was used to check the prognosis of 3 psoriasis patients, who have been treated with Sojongyuryang-tang gagambang and acupuncture.Results : PASI score decreased as a result of Sojongyuryang-tang gagambang treatment in 3 psoriasis patients. Conclusion : Sojongyuryang-tang gagambang can be effective treatment for the unhealthy diet related psoriasis when diagnosed as spleen dampness.

OSEK/VDX is a joint project aiming at an industry standard for ECUs in vehicles and OSEK OS is a real-time operating system that meets OSEK/VDX specifications. In this paper, we suggest an implementation of task switching and interrupt handling mechanisms of OSEK operating system based on ARM processors. Considering the requirements of OSEK OS and characteristics of ARM processor, we have designed task switching and interrupt handling mechanisms. For evaluating the validation of the suggested mechanisms, we have checked the functional correctness on an experimental embedded board with ARM processor and calculated the time of task switching and interrupt handling.
