It followed in system development and SMRT(Seoul Metropolitan Rapid Transit Co)System reached to an automatic train operation(ATO) and driverless operation(DLM) from the manual operation due to the train driver. The train like the general bus or the car vehicle was not serial riding in a car and the Parallel concept which the numerous passenger rides in a car simultaneously occur frequently the charge of the train driver unmanned bitterly from existing manual handling was a possibility of doing, train open door control(ODM) which bites also ATO, it handles it minimized. Like this ATO/DLM, the control system which bites being a Wayside to Train communication for immediacy, it is a system of the Vital concept the immediacy of the citizen Data evil the radio information transmission and the train of the interface which is accurate from unmanned operation and, will decipher, will accomplish it will guarantee. It respects the passenger accident prevention and an air question environment improvement from subway platform and phul leys the screen door of Platform(PSD) with the fire tube frost it refers and part it treats and to sleep it does, ODM which bites is accuracy and immediacy of altitude and when seeing from the viewpoint which demands the trust of altitude, ODM system the trust of car incest interface in the equipment construction which is safe and the comparative analysis back of the system analysis against the control which bites and case study and other subway system it leads from the research which it sees and signal - train in base grudge to sleep it contributes it does.

Objective : Because of the complex anatomical association among vascular,dural, and bony structures, paraclinoid internal carotid artery (ICA)aneurysms remain a major challenge for vascular neurosurgeons. Westudied the clinical outcomes of 61 paraclinoid ICA aneurysms after microsurgicalclipping in comparison with endovascular coiling. Materials and Methods : Between January 2008 and December 2012, wetreated 61 paraclinoid ICA aneurysms created by surgical clipping or endovascularcoiling. Preoperative neurologic status and postoperative outcomewere evaluated using the Glasgow coma scale (GCS) and themodified Rankin scale (mRS). Postoperative hydrocephalus and vasospasmwere reviewed using the patients' medical charts. Results : Most patients were in good clinical condition before the operationsand had good treatment outcomes. Clinical vasospasm was observedafter the operation in five patients, and hydrocephalus occurred insix patients. No statistically significant difference regarding aneurysm size,sex, GCS score, H-H grade, and mRS was observed between the surgicalclipping group and the endovascular coiling group. In addition, the treatmentresults and complications did not show statistically significant differencein either group. Conclusion : Surgical occlusion of paraclinoid ICA aneurysms is difficult;however, no significant differences were observed in the treatment resultsor complications when compared with coil embolization. In particular, useof an adequate surgical technique may lead to better outcomes thanthose for coil embolization in the treatment of large and/or wide-neckparaclinoid ICA aneurysms.
