[en] We have measured total hadronic cross section using 9647 multi hadron events taken by the TOPAZ detector. The luminosity measurement was improved by the Forward Calorimeter (FCL) which gives less systematic error. In this report, we present the measured hadronic cross section σ-bar_h with only QED photonic correction is made, σ-bar_h = 143.8 ± 1.5(stat.) ± 5.4(syst.)pb. This value should be compared with the Standard Model effective Born cross section, and direct comparison with the LEP measurement is possible. The value of the electromagnetic running coupling constant α-bar(58 GeV) is determined from the obtained cross section. Other plans of physics studies based on this analysis are discussed. (author)
