A relationship between the water quantity and the inflow pollutant loads of BOD, TN, and TP in So-okcheon of the upper Keum river in 2000 was investigated in this study. Daily streamflow of So-okcheon needed to compute the pollutant loads was estimated by the DAWAST model, because there is no measurement of the discharge. From a relative function of the inflow pollutant loads using DAWAST, BOD can be estimated by the relation of y= 145. 31x <sup>1.06</sup>, TN by y=598.11x<sup>0.90</sup> and TP by y=39.60x<sup>0.89</sup>.

This paper presents reducing method of profile error on a mechanical tuning for multi-spindle control of NC machine tools. To reduce the profile error in the feed drive system, it is useful to adopt same transfer function of multi spindle machine tools. By selecting the correction vector of servo rigidity and natural vibration on JK map, multi spindle control can be tuned by mechanical parameters with small profile error.<br/>

This paper presents a developing algorithm of checking errors of feed mechanism in the NC machine tool with DAC method. It is useful to check static and dynamic rigidity with relation between lost motion and current of rotor. For checking error of feed in assembly tuning with machining center proposed checking algorithm is useful.<br/>
