        Assays for detecting pregnancy-associated glycoproteins (PAGs) levels in the blood of pregnant cattle have been developed and commercialized to determine pregnancy status. This study was conducted to determine the accuracy of a PAG-based ELISA test for pregnancy detection in Hanwoo. The anticoagulated treated whole blood was sampled from 595 Hanwoo that were 28-71 d (mean 49) and 85-128 d (mean 106) after artificial insemination. At the 2nd blood collection time, a transrectal palpation test was used as the standard for pregnancy diagnosis. For PAGs and the transrectal palpation test (n=595), the sensitivity was 98.4% (pregnancy, 481/489), the specificity was 100% (open, 106/106), and the accuracy was 98.7% (pregnancy+open, 587/595). In conclusion, the rapid PAG-based ELISA pregnancy test was highly sensitive and specific for pregnancy detection in Hanwoo.

        The runoff characteristics of non-point source pollutions in the municipal area of Jeonju were investigated and analyzed by using the SWMM (Storm Water Management Model). The flow rates and water qualities of runoff from two types of drainage conduits were measured respectively. One was a conventional combined sewer system and the other was a separated sewer system constructed recently. From August to November in 2004, investigations on two rainfall events were performed and flow rate, pH, BOD, COD, SS, T-N and T-P were measured. These data were also used for model calibration. On the basis of the measured data and the simulation results by SWMM, it is reported that 80-90% of pollution load is discharged in the early-stage storm runoff. Therefore, initial 10-30 mm of rainfall should be controlled effectively for the optimal treatment of non-point source pollution in urban area. Also, it was shown that the SWMM model was suitable for the management of non-point source pollution in the urban area and for the analysis of runoff characteristics of pollutant loads.
