        신경교 세포에서 resveratrol이 amyloid-β에 의해 유도되는 Cdk inhibitor p21 및 Bax 발현의 감소 효과

        김영애,임선영,고우신,최병태,이용태,이숙희,박건영,이원호,최영현,Kim Young Ae,Lim Sun-Young,Ko Woo Shin,Choi Byung Tae,Lee Yong Tae,Rhee Sook-Hee,Park Kun-Young,Lee Won-Ho,Choi Yung Hyun 한국생명과학회 2005 생명과학회지 Vol.15 No.2

        Resveratrol (3,4',5-trihydroxy-trans-stilbene), a phytoalexin found in grape skins, peanuts, and red wine, has been reported to have a wide range of biological and pharmacological properties. $Amyloid-\beta$ deposition and senile plaque-associated astrocytes are common neuropathological features of Alzheimer's disease. In this study, we have explored the effects of resveratrol on $amyloid-\beta-peptide-mediated$ cytotoxicity in vitro and modulation of cell growth-regulatory gene products in astroglioma C6 cells to elucidate its possible mechanism for anti-cytotoxicity. Exposure of C6 cells to $Amyloid-\beta$ resulted in dose-dependent growth inhibition and morphological changes of C6 cells, which were recovered by pre-treatment with resveratrol. The anti-proliferative effect of $amyloid-\beta$ was associated with the induction of tumor suppressor p53 and cyclin-dependent kinase (Cdk) inhibitor p21 (WAF1/CIP1) expression assessed by RT-PCR and Western blot analysis in time-dependent manner in C6 cells. In addition, the pro-apoptotic Bax expression was also up-regulated in $amyloid-\beta-treated$ C6 cells without alteration of anti-apoptotic Bcl-2 and $Bcl-X_L$ expression. However, pre-treatment of resveratrol significantly inhibited $amyloid-\beta-induced$ p53, p21 and Bax levels, suggesting that the modulation of p53, p21 and Bax levels could be one of the possible pathways by which resveratrol functions as anti-cytotoxic agent. Our results demonstrate that resveratrol may enhance the protection against $amyloid-\beta-induced$ cytotoxicity by promoting the survival of glial cells. Resveratrol (3,4',5-trihydroxy-trans-stilbene)은 포도와 같은 식물에서 각종 감염균으로부터 자신의 몸을 보호하기 위하여 생성되는 물질인 phytoalexin의 일종으로 강력한 항산화작용, 암예방 효과 및 항암 작용을 포함한 각종 약리작용을 가진 것으로 보고 되어져 오고 있다. Alzheimer 환자의 뇌에 축적되어 뇌 신경세포를 죽이는 amyloid plaque의 주 성분은 $amyloid-\beta$의 축적에 의한 것인데, $amyloid-\beta$는 정상적인 단백질 신진대사 과정의 결과로 체내 모든 세포들로부터 생성되는 물질이다. 본 연구에서는 resveratrol의 세포독성 보호효과에 관한 효능을 검증하기 위하여 C6 신경교세포에서 $amyloid-\beta-peptide$ (fragment 31-35)에 의한 세포독성 및 세포성장 조절관련 주요 유전자들의 발현에 미치는 resveratrol의 영향을 조사하였다. $Amyloid-\beta$가 처리된 C6세포는 처리 농도의존적으로 증식이 억제되었으며, 형태적 변형도 유발 되었으나 resveratrol의 전처리에 의하여 효과적으로 차단되었다. RT-PCR 및 Western blot analysis에 의한 결과에서 $amyloid-\beta$ 처리에 의한 세포증식 억제는 종양억제유전자 p53 및 Cdk 억제제인 p21 (WAF1/CIP1) 발현이 증가되었다. 또한 apoptosis 유발에 매우 중요한 역할을 수행하는 Bax의 발현도 $amyloid-\beta$가 처리된 C6 세포에서 발현이 증가되었으나 apoptosis 유발억제에 관여하는 Bcl-2및 $Bcl-X_{L}$ 발현에는 큰 영향을 미치지 못하였다. 그러나 resveratrol이 전처리된 세포에서는 처리 농도 의존적으로 $amyloid-\beta$에 의해 유도되는 p53, p21 및 Bax의 발현이 정상수준으로 회복되었다.

        독일 경제아카이브즈의 형성과 유형

        The term 'Business Archives' is not familiar with us in our society. Some cases can be found that materials are collected for publishing the history of a firm on commemoration of some decades of its foundation. However, the appropriate management of these collected materials doesn't seem to be followed in most of companies. The Records and archives management is inevitable in order to maximize the utility of Information and knowledge in the business world. The interest in records management has been grown, especially in the fields of business management and information technology. However, the importance of business archives hasn't been conceived yet. And also no attention has been paid to the business archives as social resources and the responsibility of the society as a whole for their preservation. The company archives doesn't have a long history in Germany although the archives of the nation, the aristocracy, communes and churches have a long tradition. However the company archives of Krupps which was established in 1905, is regarded as the first business archives in the world, It means that Germany has taken a key role to lead the culture of business archives. This paper focuses on the process of the establishment of business archives in Germany and its characteristics. The business archives in Germany can be categorized in three types: company archives, regional business archives and branch archives. It must be noted here that each type of these was generated in the context of the accumulation of the social resources and its effective use. A company archives is established by an individual company for the preservation of and use of the archives that originated in the company. The holdings in the company archives can be used as materials for decision making of policies, reporting, advertising, training of employees etc. They function not only as sources inside the company, but also as raw sources for the scholars, contributing to the study of the social-economic history. Some archives of German companies are known as a center of research. A regional business archives manages materials which originated m commerce chambers, associations and companies in a certain region. There are 6 regional business archives in Germany. They collect business archives which aren't kept in a proper way or are under pressure of damage in the region for which they are responsible. They are also open to the public offering the sources for the study of economic history, social history like company archives, so that they also play a central role as a research center. Branch business archives appeared relatively late in Germany. The first one is established in Bochum in 1969. Its general duties and goals are almost similar with ones of other two types of archives. It has differences in two aspects. One is that the responsibility of the branch business archives covers all the country, while regional business archives collects archives in a particular region. The other is that a branch business archives collects materials from a single industry. For example, the holdings of Bochum archives are related with the mining industry. The mining industry-specialized Bochum archives is run as an organization in combination with a museum, which is called as German mine museum, so that it plays a role as a cultural center with the functions of exhibition and research. The three types of German business archives have their own functions but they are also closely related each other under the German Association of Business Archivists. They are sharing aims to preserve primary materials with historical values in the field of economy and also contribute to keeping the archives as a social resources by having feed back with the public, which leads the archives to be a center of information and research. The German case shows that business archives in a society should be preserved not only for the interest of the companies, but also for the utilities of social resou

      • 독일의 아키비스트 양성제도 - 마르부르크 기록학교(Marburg Archivschule)를 중심으로 -

        김영애,Kim, Young-Ae 한국기록학회 2000 기록학연구 Vol.0 No.2

        In this paper I tried to get an overall view of the training course of German archivists, based on the curriculum of Marburger Archivschule. In Germany the short-term training courses are offered by some archives and also graduate-level course is offered by a college in Potzdam. Marburger Schule is, however, said to be a representative institute for training of archivists in Germany because the institute has a long history and its graduates have been playing a leading role in the archival science and archival administration of Germany. By examining the curriculum of the Marburger Schule, I tried to analyze the important elements which have decided the shaping of curriculum historically. I also examined the general prerequisite to be an archivist in Germany, including qualification-examination in order to see how the high standards of German archivists can be maintained. There are three kinds of training courses in Marburger Schule: course for academic archivists, course for administrative archivists, short-term course for complementary training. The former two main courses are runned in association with each state archives(staatliche Archive, Landesarchive) in the Federal Republic of Germany along the line of public regulation. These courses consist of theoretical and practical education. Marburger Schule is charged with the theoretical education, while each local government(Landesregiergung) runs the training system according to its own rules with autonomy. The education of archivists must be structured to fill the expected role in a society to which archivists belong. The image of archivist changes in the course of times and makes a greate many differences according to the conditions and tradition of a country. The whole system of formal education is also related with the style of managing of Archives in each country. Therefore an example of a country can not be taken so easily as a model. The education system of archivists must be interpreted in the relation with the historical condition of a country and its administrative system of archives.

        모성연령과 출산순위의 변화가 저체중아 출생률에 미친 영향

        김영애,박정한,Kim, Young-Ae,Park, Jung-Han 대한예방의학회 1989 예방의학회지 Vol.22 No.2

        모성연령 및 출산순위의 변화가 출생시 체중에 미치는 영향을 알아보기 위하여 부산시내 1개 대학병원, 5개 종합병원,1개 병원, 1개 의원, 1개 조산소에서 분만된 1977년 7,786건과 1987년 8,671건의 단태아를 대상으로 산실의 분만대장에서 출생시 체중, 모성연령 그리고 출산순위를 조사하였다. 모성 연령은 1977년에 25-29세가 56.4%, 30-34세가 18.8%였으나 1987년에는 25-29세가 65.1%, 30-34세가 21.6%로 증가하였으며, 24세이하군과 35세 이상군의 출생아 비율은 감소하였다. 출산순위별 분포는 1977년에 1,2순위 출생아가 각각 56.9%, 28.8%였는데 1987년에는 각각 59.9%, 36.8%로 증가한 반면 3,4순위는 1977년에 10.6%, 3.6%에서 1987년에 각각 2.8%, 0.5%로 감소하였다. 저 체중아 출생률은 1977년에 5.3%였는데 1987년에는 4.0%였고, 이 가운데 직접표준화법을 응용하여 추정한 모성연령 및 출산순위별 변화가 저체중아 출생률 감소에 기여한 것은 10.7% 이었다. 나머지 89.3%는 모성 연령 및 출산순위별 저 체중아 출산률의 감소에 기인한 것이다. The objective of this study was to examine the impact of changes in maternal age and parity distribution on birth weight. The study population included 7,786 single live births in 1977 and 8,671 single live births in 1987 delivered at 9 medical facilities in Pusan. Data were obtained from the delivery record. The proportion of infants born to the mothers of 25-29 years increased from 56.475 in 1977 to 65.1% in 1987 and the proportion to the mothers of 30-34 years increased from 18.8% in 1977 to 21.6% in 1987. In the same period, the proportions of 1st and 2nd birth order were increased from 56.9% and 28.8% to 59.9% and 36.8%, respectively. The proportion of infants born to the age group of ${\leq}24\;and\;35{\leq}$ years were decreased in 1987. The proportion of births of the third or higher birth order was decreased from 14.2% in 1977 to 3.3% in 1987. Low birth weight (<2500gm) incidence rate was 5.3% in 1977 and it was decreased to 4.0% in 1987. It was estimated that changes in maternal age-parity distribution accounted for 10.7% of the decreased in low birth weight incidence rate. Rest of the change (89.3%) was attributed to the reduction of age-parity specific low birth weight incidence rate. Application of the direct adjustment method was considered to be an adequate tool for evaluating the impact of family planning on neonatal health.

        김영애,최목화,박정아,Kim, Young-Aee,Choi, Mock-Wha,Park, Jung-A 한국주거학회 2013 한국주거학회 논문집 Vol.24 No.1

        Number of children cared by child care centers has getting up almost half of the from zero to five year age group in korea. Home care children' activities are reported more active and natural than those of center care children. So this study seek the design guidelines for the residential core model of child care centers as second home in korea. The residential core model by Anita Lui Olds was selected and ten domestic center cases were surveyed for guidelines. Firstly, daily-residential core model is learning by daily life at home, and is equiped with cooking kitchenet and group activity area in group room. Secondly, play-residental core model is learning by playing by self, and is equiped with acting, eating and reading common area clustering two or three group room. Thirdly, eco-residental core model is learning by eco-friendly activities, and is equiped with companying, cooperating and sharing area. Fourthly, project-residental core model is learning by project by self, and is equiped with drawing, experimenting and presenting common area. Fifthly, the space of residential core model is organized with three or four group room and clustering living or common area. The larger the center is, the more the cluster is vertically. Facility area and outdoor playground per child is about 7 and $3m^2$.
