In complex commercial facilities, tenants are critical factors in terms of their competitiveness, and tenant mix is a decisive factor in creating malls` concepts. This study investigates the effect of tenant characteristics on rental rate in complex shopping mall. The case mall of this study is Western Dome that is an open air mall in Ilsan. We set the independent variables for this study by distinguishing tenant characteristic variables and physical characteristic variables, and conducted variance analysis and multiple regression analysis. With empirical research, we confirm tenant characteristics have an effect on the rental rate of complex shopping mall. The empirical research shows tenants of food and beverage, accessory, cosmetic etc. pay relative higher rent, but tenants of culture and entertainment pay relative lower rent. And we also find out physical characteristics such as store size, corner location, connection to main street, main entrance distance, etc. have influence on the rental rate. This study shows tenant characteristics should be considered in determining rental rate of complex shopping mall.

An electrical railway system uses high voltage system for train traction and low voltage system for train control. Railway systems are broadly distributed across mountains, sea sides and cities. Electrical accidents provoke the death and injury of a human being and the damage of the equipment by the overcurrent due to the catenary dropping and by the overvoltage due to lightning. Grounding systems are adopted for the protections of the system from the overcurrent and the overvoltage. Isolation grounding for each system can be easily installed. However, the closed circuits between grounding systems can be occurred. The currents flow through the closed circuits cause the abnormal operation of the system. To overcome the problem of the isolation grounding, the equipotential bonding is usually adopted. The equipotential bonding should have very small grounding resistance. In this paper, we showed the transition from the isolation grounding system to the common grounding system and presented the comparison and the analysis of two grounding systems by simulation. In addition, we proposed the direction for a new grounding system of electric railway.
