The role of brake is safely to transport passenger & cargo and stop vehicles at emergency in railway vehicle. Brake system reduces the speed by control command of electricity or air. mechanical methods to perform brake are disk brake & tread brake. This study targeted development of highly efficient sintered alloy brake shoe in railway vehicle whose high frictional coefficient wear resistance compatibility of the existing tread brake shoe & minimization of wheel's thermal damage and performed development of friction material's formulation analysis of pressure distribution in wheel tread & brake shoe optimum form design through analysis of heat flow.

As a result of the examination analyzed loop type of Detecting the Broken Rail Monitoring System as a part of prevention of train derailment, installed in the Seoul Metro No. 2 subway line 98.51m section which is Samsung to Seolleung, we found that it is possible to detect crack location(Thermit welding: 48.18m) within the margin of error of ±1m accurately As analysis of the first day, third day, fifty day, and seventh day periodically, we found that Fresnel reflection happened where the crack location 48.18m. However other 3 branches show loss by bending of optical cable(spread reflection from the outside impact)

This study, taking into account the great importance of private education in Korean Education, attempts to analyze current problems facing private schools and on the basis of this analysis, to search for policy directions in order to solve those matters. As a whole, the dependancy of education in Korea on the private sector is very high. But most institutions of private education are in financial difficulaties. In supporting private schools, above all, the governmental policy directions can be fostered as the following. 1. Financial aid should be raised to the private schools. Governmental subsidies for private schools should be intensified in view of the discontinuation of the gap between private and public schools. 2. It is hoped that a private educational treasury would be founded. For the establishment of this treasury, a 3-year preparatory period is needed and during the period various investments should be implemented. 3. To improve the quality of education the teacher recruitment policy should be changed in middle and high schools from the recommendation method to an open contest method 4. To raise the efficiency of the administrative system pertaining to private schools it would be set up an administrative office so that private schools could play roles in planning and policy making. The office could handle the tasks of control and establishment of private educational institutes, and could be change with the task of financially supporting private schools and private education.
