Shaving for adult men is one of the essential requirements for life. For physiological reasons, most adult men have beards, and if men trim their beards and take good care of them, their appearance becomes cleaner. If a dull blade is used for a wet razor, or if an appropriate massage is not used, skin irritation may occur, resulting in shaving wounds. Therefore, the convenience and comfort of the razor are required as much as the skin becomes smooth after shaving. In this paper, a pre-shaving method of sound massage was proposed to reduce the irritation of wet shaving on the skin and increase the convenience of shaving. It softens the skin or secretes oil through non-face-to-face low-frequency speakers to increase skin gloss, making shaving smooth and safe. We recorded the sound of the wet shave state to determine the skin condition before and after the wet shave, and objectively compared and analyzed the effect with this sound spectrum. In other words, it can be seen from the experimental results that the sound massage before shaving reduces the friction between the razor and the skin and the skin and beard by -7.0 dB, improving the skin wound of the wet shave and achieving a refreshing shave.

The foliage of variegated Solomon's seal is excellent in cut flower arrangements. However, it has a restricted marketing period because the harvesting is limited in spring and summer. The increased interest requires the year-round production, thus techniques for dormancy breaking and forcing without low temperature treatment is needed. Therefore, experiments were conducted to d etermine whether gibberellic acid (GA) could break dormancy in variegated Solomon's seal. Thes prouting of dormant bud did not occur throughout the experiment when $GA_3$ $400mg{\cdot}L^{-1}$ was applied to dormant rhizomes as a soil drench. However, when plants were treated with a GA drench after scratch with razor blade or were given direct injection of GA, percent sprouting was increased up to 100 or 83.3%, respectively. However, because treatments with razor or syringe may damage internal organs, we tested another method, scarifying the rhizomes with sodium hypochlorite (NaOCl). Rhizome scarification with 4% NaOCl for 6 or 24 hours followed by drench of $GA_3$ $400mg{\cdot}L^{-1}$ increased the dormancy breaking percentage to 70 or 86.7%, respectively. Moreover, scarified and GA-treated rhizomes produced more leaves than untreated or GA-soil drenched plants in the glasshouse. These results showed the possibility of year-round production of variegated Solomon's seal foliage with rhizome scarification and GA treatments.
