The purpose of this study was to research for anti-oxidation and anti-wrinkle effects of Acar mono Sap (AM). To cosmetic effect of AM, safety effect (MTT assay), anti-wrinkle effect (elastase, MMP-1 inhibition assay) and anti-oxidant effect (DPPH assay) were measured. When water extract of AM was used for cell viability, it was over 100% at 6% (6 ml/100 ml in phosphate buffer) concentration. AM showed 45.7% elastase inhibition and 23.7% MMP-1 inhibition at 50% (50 ml/100 ml in phosphate buffer) concentration so that it had good anti-wrinkle characteristic. And AM showed 68.9% antioxidation capacity at 50% concentration by using a DPPH assay. Consequently, AM can be used as natural materials or additives for human skin owing to their beneficial biologic functions, including the anti-wrinkle effect, for cosmetic compositions.

송배전선로 자동화 공법과 관련한 일반적인 기술들이 이미 선진외국에 의해 많이 개발되어졌으나 선로 구성 및 지형적 특징으로 인하여 외국으로부터 기술도입을 통하여 그대로 활용하기는 어려운 실정이다. 본 연구에서는 송배전선로의 자동화 공법 기술개발 방향수립을 위하여 송배전 작업 현황 및 선진외국의 송배전 자동화 작업 신공법 기술동향을 분석하고 작업자의 안전과 직접적으로 관련이 있는 송배전 활선 작업 현황을 조사하였다. 또한 국내외 활선작업용 로봇 개발 및 적용현황을 조사 분석하고 활선작업용 로봇 개발을 위한 요소기술을 검토하였다. 이를 통하여 국내 적용 가능한 활선작업 신공법의 적용방안을 제시하였다.

There have been developed in authentication systems for information using biometric information approaches such as fingerprint, face, and iris. In general, a door-lock system is operated by touching keypads, which remains fingerprints on the keypads. Such door-lock systems do not protect personal information from others due to the exposure of fingerprints to keypads. In this paper, we propose the new door-lock system that does not leave fingerprints on the keypads. Without touching keypad the system works because the system accepts authentication information by using illuminance sensor and LED. The experiment shows that the implemented door-lock system works well under any circumstance.
