This research paper is intended to investigate the supply chain operational performance and its potential factors that constitute an efficient supply chain operational performance in Japan and China. In order to perform this, the SCM Logistics Scorecard (LSC) has been utilized as a selfevaluation tool for participating companies. The LSC focuses on four decisive areas, namely, company strategy, planning and execution capability, logistics performance, and IT method and implementation. The number of participating companies was 554 from Japan and 236 from China. The scores in each assessment area were compared between the two countries. Subsequently, factor analysis has been conducted by using the result of LSC in order to identify the significant factors which established the operational performance of SCM in each country. The result of the factor analysis indicated that the structure in generating successful SCM in Japanese industry and the Chinese were considered similar in the aspect of SCM realization, SCM strategy and the utilization of IT along the chain. Finally, the correlation between extracted factors and financial bottom lines was conducted, which indicated that improving SCM performance brought positive impact on financial outcome, especially when IT utilization in cooperation with SCM organization strategy.

Even identical rainfallintensity witl different distribution of rain drops diameters can result in different received power by rader, so it is difficult to determine precise rainfall intensity for all types of rainfall from received power by radar. In addition, because a radar beam passes 5003,000M Above ground level, rainfall intensity obsevred by radar does not necessarily coincide with the ground rainfall intensity.In thie paper the authers discussed the method of improving coherency between the current scene of a radar raingauge and ground rainfall by uaing past observed data of a radar raingauge and ground raingauges, and could find techniques yielding a certain degree of success.
