<p>Aerodynamic drag on several types of road cones was measured by wind tunnel experiments purposing improvement of anti-fall-down functions against lateral wind blowing. By opening holes on the side surface of cones, drag coefficient decreased so that maximum endurable wind speed increased over 30 m/s in the best case. This finding contributes to three benefits in road safety; reducing the weight of the cone for workers at roads, cost cutting by manufacturers for the synthetic resin material, and also for security aspects by internal visibility preventing from hidden matters. We also found different aerodynamic characteristics due to bottom plate condition of the cones. That is, when the bottom plate opened to the inner space of the cone, small angle of inclination intensified a recovery moment that pulls back the cone to the standing attitude. This effect significantly improved the maximum endurable wind speed and was explained by the flow allowed inside the cone when the side holes were provided. Such a fluid-structure interaction was analyzed theoretically to clarify the endurance mechanism.</p>

The glechoma hederacea subsp. grandis( G. grandis) is used as an herbal medicine and is supposed that the extract at the time of the bloom shade-drying is effective against a child's convulsion. Moreover, it may be considered as reduction of blood sugar level. In this study, the clinical test of the hair growth facilitatory effect of the G. grandis extract in human during one to three years showed remarkable improvement or a little improvement by evaluation at 95%(41 persons among 43 persons). With the mice, the tendency for hair growth was promoted compared with a control( physiological saline). Furthermore, we used the hair follicle organ culture system for the hair growth promoting substance from G. grandis extract. As a result, G. grandis in the growth phase after the bloom had remarkable growth effect, and found out having the remarkable hair growth effect in a fraction of aqueous phase from the extract especially. This aims at the establishment of the hair regenerative technology which utilizes the natural plant, G. grandis. It is possible to apply to the baldness and the alopecia caused by various factors, and preventive effect for the depilation, trichogenous, and the hair restoration action improve synergistic and it is effective as the external application medicine for the head with high safety compared with the scalp.
