Various herbal medicinal extracts were examined for the development of cosmetic products with anti-oxidative and anti-wrinkle activity. First, total polyphenol contents and DPPH radical scavenging activities of herbal medicinal extracts were measured. Most herbal samples, except for DW extracts of Portulaca oleracea, Caesalpinia sappan, Taraxacum platycarpum, Carthamus tinctorius, and 70% EtOH extracts of Taraxacum platycarpum and Carthamus tinctorius, showed DPPH radical scavenging activity over 80% at a concentration of 400μg/ml. SOD-like antioxidant activity of DW extracts of Syzygium aromaticum, DW extracts of Eriobtrya japonica and 70% EtOH extracts of Sophora japonica was measured as 40%, 35% and 80%, respectively at a dry matter concentration of 50μg/ml. In elastase inhibition assay, DW extracts of Lycium chinense (50μg/ml) and 70% EtOH extracts of Areca catechu (50μg/ml) showed 50% and 40% of inhibition, respectively. At a concentration of 1.250μg/ml, DW extracts of Lycium chinense and 70% EtOH extracts of Areca catechu showed 10% and 30% of collagenase inhibition, respectively. Skin and lotion samples were prepared using the two herbal extracts of high anti-wrinkle activity: Lycium chinense extract and Areca catechu extract. The storage stability of skin and lotion containing each of the selected herbal extracts was evaluated. pH and viscosity were used as stability indicators for the stability test under different storage temperatures and freeze-thaw cycle conditions. The skin and lotion containing each of DW extract of Lycium chinense and 70% EtOH extract of Areca catechu was showed high pH and viscosity stability. The skin and lotion containing DW extracts of Lycium chinense showed relatively higher stability than the skin and lotion containing 70% EtOH extract of Areca catechu, at cycle chamber and freeze-thaw conditions. In summary, these results indicated that cosmetics containing DW extract of Lycium chinense were relatively stable, and this herbal extract could be used as a stable functional cosmetic material.

우리나라 연안컨테이너운송 서비스는 1995년 이후 한진과 대한통운이 연안항로에 전용선을 투입하여 운송서비스를 실시하였으나 연안컨테이너 물동량의 감소로 인하여 운항채산성이 악화되어 1999년 대한통운이, 2006년 5월에는 (주)한진이 연안컨테이너운송서비스를 중단하였다. 이로 인하여 국내외 선사들은 우리나라 항만간에 발생하는 환적화물의 처리 및 적시 운송에 어려움을 겪고 있다. 화주측면에서도 연안운송이 아닌 도로운송 등을 이용함으로써 물류비의 증가는 물론 운송지체에 따른 시간적 손실이 발생하고 있다. 따라서, 본 연구는 국내 연안컨테이너운송체계의 현황과 문제점을 파악하여 그 해결방안으로 몬테카를로 분석기법을 통해 컨테이너 연안운송분야에 외국적 외항선박이 투입되었을 경우의 경제적 효과에 대해 분석하였다.
