The analysis provided evidence to suggest that both net income and cash flows from operating activities are functioned as financial performance measures with similar properties. We also find that capital efficiency is an important factor. Furthermore, there is also evidence that cash flows from investing activities and cash flows from financing activities have a common factor.No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671472019ライフサイクルを考慮した企業の成長要因93111ENTakahisaKoshidaToyotakaNakagawaHidekazuNagahata10.18926/56507No potential conflict of interest relevant to this article was reported.岡山大学経済学会Acta Medica Okayama0386-30692541994Approximation Formulas for the Lower Confidence Limits of Process Capability Indices301314ENYasushiNagataHidekazuNagahata10.18926/OER/41789No potential conflict of interest relevant to this article was reported.Acta Medica Okayama11999Automatic Micromanipulation System using Stereoscopic Microscope327331ENTetsuyaSanoHidekazuNagahataHidekiYamamoto<p>In this paper, we developed a visual feedback system that controls a micromanipulator so that a needle head may reach a target. The system consists of a stereoscopic microscope, a micromanipulator, two CCD cameras and a personal computer. The position of the target and the needle head under stereoscopic microscope are measured three dimensionally by using two CCD cameras which are set to eyepieces of the microscope. It is necessary that the image processing employed be fast so that the micromanipulation can be carried out at a realistic rate. The image processing time for detecting the target and the needle head is greatly reduced by using image compression </p>No potential conflict of interest relevant to this article was reported.Acta Medica Okayama12006Design Support System for Japanese KimonoENTetsuyaSanoHidekazuNagahataHidekiYamamoto<p>The Japanese kimono has the same shape and the basic size, regardless of the wearer's form.
