In this study, we investigated the anti-oxidative effects, antimicrobial, and anti-inflammatory activities of the extracts from broccoli to evaluate its use as a functional ingredient in cosmetics. The extracts are WE (water extract at RT), MWE (mineral water extract at RT), EE (70% ethanol extract at RT), and USEE (heat process for 12 hours at 60℃ after ultrasonification for six hours with 70% ethanol). The measurements of the total polyphenol content from broccoli extracts were highest in EE at 425.24±13.9 mg/g dry. The result of electron donating ability of EE was the highest at 10,000 ㎍/㎖ as 97.81% and increased in a concentration-dependent manner. The ferric reducing antioxidant powder (FRAP) of EE was the highest at 10,000 ㎍/㎖ as 1235.6 μM. In an antimicrobial activity test, the EE showed significant antimicrobial activity against S. epidermidis, S. aureus, E. coli, P. acnes, and P. ovale. Furthermore, broccoli extract exhibited no cytotoxicity in RAW 264.7 cells. Also anti- inflammatory activity by NO assay showed LPS-induced NO was significantly inhibited following treatment with EE of 1,000 ㎍/㎖. Therefore, the broccoli ethanol extract can be used as a resource of natural cosmetic material for functional cosmetics.

조대우 충남대학교 경영경제연구소 2001 경영경제연구 Vol.24 No.1

대덕밸리는 지난 20여년간 기초기반연구의 산실로서의 국가정책적 역할을 충실히 수행하여 왔다. 1990년에 접어들면서 태동된 벤쳐기업들이 IMF사태이후 우리 나라의 미래를 결정하는 중요한 전략대안의 하나로 선택되면서 대덕연구단지의 중요성은 지역차원을 넘어 국가적 차원으로 승화되기에 이르렀다. 대덕밸리의 벤쳐기업은 엔지니어가 보유기술의 수월성을 기반으로 기업을 설립하였으나 설립하는 순간 경영자로서의 역할을 수행해야 하는 과제에 봉착하게 된다. 본 연구에서는 대덕밸리로 옮겨온 지 7년째가 충남대 경영대학원은 새로이 등장한 신세대 벤쳐기업인들을 어떻게 교육할 것인가에 관심을 갖고 이들을 새로운 경영연구의 대상으로 또한 새로운 경영자교육의 대상자로 생각하고 새로운 사회적 수요를 경영대학원 프로그램에 어떻게 수용할 것인가를 살펴본후 예시적 대안을 제시하였다.

In this paper, an integrated developing environment(IDE) for a biped robot is presented, through which a new path planning algorithm is designed. The IDE is composed of four modules, each of which is designed by using the object-oriented programming techniques. Four modules have the capability of gait control, path planning, mission-level language interpretation, and monitoring respectively. Also, each module exchanges its information each other through database. The new path planting a1gorithm is composed of an environment analysis algorithm and a path search algorithm, and is used in the IDE. In this paper, an extended visibility graph algorithm is proposed as the environment analysis algorithm and the A algorithm is used as the path search algorithm for the path planning of biped robots. Since the path planning a1gorithm is designed by using the object-oriented techniques and is also implemented within the IDE, it has a good adaptability to the changes of algorithm and construction, and also has a high reusability of the designed capabilities.

新安海域의 海洋學的 特性에 관한 硏究

The purpose of this study is to investigate and analyze the physical and chemical characteristics (water temperature, salinity, pH, DO, COD, transparency, solid solution, and nutrient) of the Shinan sea area extending from February to November in 1992 and to contribute to the protection of sea ecosystem and sea environment through research on sea pollution. The following are the results. The water temperature of the continental side sea was lower in winter and higher in summer than that of the island side sea. This seems to have resulted from the difference of specific heat between in land and in sea. Salinity was highest in April and lowest in August. This may be viewed in the way that much precipication and fluctuation of land water from the mouth of Mokpo in the rainy season, summer, have influenced on the salinity of the above sea area. The range of pH proved to be rather high in summer. This seems to have resulted from the features of atmosphere and land and water distribution of this area. DO was highest in February and lowest in August on account of the influence of water temperature and activities of marine inhabitants. But COD was highest in August and lowest in April. This also had a close relation to water temperature and activities of marine inhabitants. Judging from the standard amount of inhabitant environment of marine organisms, 2 mg/l, the above-mentioned area was found rather clean. Transparency was high in summer and low in winter. This may be viewed in the way that the shallow soundings and monsoon had an influence on the spout of marine deposits such as silt and clay. Solid solution was high in spring and winter. The correlation coefficient to the transparency was r=-0.927 in the continental side sea and r=-0.845 in the island side sea. This showed reverse distribution. PO4-P was high in spring and winter and low in summer and autumn. This resulted from the fact that the amount of consumption decreased in winter on account of the weakening of plankton multiplication, while the amount of supply increased on account of the decomposition of the animal dead bodies. NH_4-N was high in spring, when all living creatures are enlivened. NO_2-N and NO_3-N was high in autumn owing to the cycle process of nitrate. DIN was high in autumn and winter and the Shinan sea area was found one of the malnourished area in total nitrogen quantity The correlation coefficient between PO_4-P and DIN in the continental side sea was r=0.368 on the surface and r=0.821 at the bottom, while that in the island side sea was r=0.6833 on the surface and r=0.895 at the bottom. This showed that the island side sea was higher and more stable in correlation than the continental side sea. According to the above results, the author found that the Shinan sea area was one of the malnourished and rather clean sea area and was proper for an ecosystem environment.
