The Communication Based Train Control(CBTC) System generally used to improving existing lines in the world is efficient and stable for improvement. Also it is efficient for improvement because it does not cause any problems in operation of existing lines. We examined the mixed operation scheme for more efficient and stable improvement when improvement is implemented depending on aged equipment and the increased number of passengers in the Korean city railroad. The biggest point in the mixed operation is to implement a stable test without interfering with the operation of the existing lines. For this purpose, we deduced a method of installing the equipment, a method of testing depending on the installed equipment, and the types of mixed operation, and presented a scheme of execution of the methods depending on the mixed operation.

Objectives The purpose of this clinical trial was evaluate the safety and efficacy of Mahwangjeongcheon-tang (MJT). Methods Twenty six volunteers were recruited as subjects. They were divided into two groups, which were MJT test group and placebo group. The investigated items related to the safety were the weight, the results of renal function and liver function. The investigated items related to the efficacy are the results of the spirometer, the clinical asthma measurement scale in oriental medicine-V (CAMSOM-V) and the quality of life questionnaire for adult Korean asthmatics (QLQAKA). Results There are no difference in the weight, the results of the renal functions and the liver functions between MJT test group and placebo group. There are the some differences in the result of the questionnaires related to the efficacy between MJT test group and placebo group.

ERTMS/ETCS Level 2 is currently planning, making contract, constructing and operating at several lines in European well-developed railway countries different from past ten years ago, and applying extensively for purpose of its inter compatibility and operational efficiency, and economic feasibility. On the other hand, ATP system correspond to ETCS Level 1, which was domestically introduced in early 2000, has introduced, operated, and planned or constructed in national railway network, but the lines, which its improvement period is come, are being occurred starting Gyeongbu Line. Therefore, we study the consideration and construction plan by stages if LTE-R Korean Radio-based Train Control System for conventional & high-speed railway under domestic development is extensively applied as the third National Railway Network Construction Plan was announced.
