Runoff and nutrient concentrations were monitored to identify pollutant load characteristics of a subwatershed in the Jooam lake. Observed concentrations of T-N and T-P were $1.445{\sim}3.980mg/{\ell}\;and\;0{\sim}0.273mg/{\ell}$, respectively. Runoff load of T-N, T-P by single storm occurred June 24th 2001 contributed 55% of T-N and 41% T-P of total pollutant load during study period.

In this research, a precast concrete slab with two ribs was developed to increase the stiffness of slab. The developed precast slabs are allowed to cast concrete for multi stories and to construct concrete slabs without any props. Seven concrete slabs were tested to investigate the behavior of the developed precast slabs. Test results indicated that the developed slabs showed a similar behavior with the slabs without ribs.

HEMU-400X train have been developed and will be operated over 350km/h. In this paper, the influence of vertical alignment on running behavior and safety for HEMU-400X train was instigated by numerical analysis. The wavelength and amplitude of vertical alignment were considered in scenario of this numerical analysis. This research is based on just numerical analysis and the final result which include measurement will be published in the future.
