In the 21st century, the traffic culture is changing suddenly with the advent of high-speed train era so called the traffic revolution age. The policy management for inducing the creativity becomes important for research institutes since the research institutes play an important role for the lead and distribution of new technologies. Therefore, the approach strategy of this investigation is based on the viewpoint of the organizational culture for better performance of research and development through stimulating inducements of creativity and active action of members. A questionnaire survey was performed on five research institutes including a professional railway research institute (PRRI) and four industrial research institutes for the current research, and a development plan for organizational culture of a PRRI has been presented based on the comparison study between two different types of research institutes.

In this study, the relation between the rotation which are usually caused by the creep of the contact wire, the bar geometry and the forces(wire tensions) for the triangle-shaped distribution bar and straight-shaped one in dependent tensioning device system is reviewed. According to the result, a rotation of distribution bar in triangle-shaped one modifies the distribution of the tensions between the three wires hooked in a distribution bar. On the contrary, a rotation on the straight-shaped one leads to no tension distribution change. Therefore, to use the straight-shaped distribution bar instead of triangle-shaped one is recommended. In addition, the design contents of the distribution bar which will be used in electrification of Gyeongbu line are described in this paper.
