전통건축물은 인류가 살아오면서 만들어 온 수많은 문화유산 중 하나로서 인류의 과학기술과 역사적인 사실들을 투영하고 있는 소중한 문화유산인 동시에 중요한 기록문화유산이다. 전통건축물은 건축물 자체로도 중요할 뿐만 아니라 그로부터 파생되는 그림, 도면, 단행본 등과 같은 여러 매체로도 표현된다는 특징을 가지고 있다. 이러한 관계들을 표현하고 전통건축물과 그에 관련한 기록물을 효율적으로 관리 보존 활용하기 위하여, 본 연구에서는 국내 외 문화유산 관련 메타데이터 현황을 알아보고 문제점들을 분석하여 이를 바탕으로 FRBR모형에서 제시하는 1집단 4계층의 논리구조 기반의 전통건축물 메타데이터 스키마를 제시하였다. As one of various cultural heritages created by humanity, traditional architectures are an archival heritage and cultural heritage reflecting social trends and historical facts. These traditional architectures show various features depending on characteristics by local areas and climatic conditions. They can be expressed in diverse formats such as a picture, a floor plan, and a book. For managing and retrieving traditional architecture records, it is necessary to develop metadata schema based on the FRBR model. Accordingly, this study analyzes the current situation and the problem of domestic and foreign metadata schema related to cultural heritage, and proposes the FRBR-based metadata schema for managing the traditional architecture.

N/A Background: Cushing's disease is a hypercortisolic state attributable to hypersecretion of ACTH at pituitary gland Most of these diseases are due to pituitary microadenoma. Selective removal of adenoma by transsphenoidal microsurgery is the treatment of choice for Cushing's disease. We evaluated 25 cases to analyze results of transsphenoidal microsurgery and to identify prognostic factors that may predict successful outcome. Methods: From 1989 to 1995, 25 patients were diagnosed as having Cushing's disease in Seoul National University Hospital. They were underwent pituitary microsurgery and confirmed to have pituitary microadenoma radiologically and pathologically. About these patients. retrospective evaluation was done. Results: The patients consist of 21 females and 4 males and the age was ranged from 23 to 49 years. 19 patients (76%) were judged as immediate remission. The preoperative clinical, hormonal, and radiological characteristics of the remission and failure groups were similiar The patients who were immediate remission were followed from 3 months to 72 months. 3 patients had recurrences(15.8%) at 4, 8, 49 months after operation. The pre and postoperative clinical, hormonal, and radiological characteristics of the long-term remission and recurrence groups were similiar. We could not find any predictable factors of surgical outcome. Conclusion: The first line trearment of Cushing's disease is transsphenoidal microsurgery. However considering relative late and high rate of recurrence of Cushing's disease following curative surgery, careful longterm follow up is mandatory.

${\gamma}-Al_2O_3$을 불화한 촉매상에서 아세틸렌으로부터 1,1-difluoroethane을 합성하는 실험을 반응물질의 몰비와 접촉시간, 그리고 반응온도를 변화하여 실시하였다. 촉매의 불화는 무수 불화수소로 고온에서 행하였다. 제조된 시료는 XRD에 의한 결정성, 질소 흡착에 의한 세공성, 그리고 피리딘-IR과 암모니아-TPD에 의한 산 특성을 측정하였다. 촉매의 활성은 ${\gamma}-Al_2O_3$가 불화됨에 따라 향상되었고 반응온도 $200^{\circ}C$ 정도에서 원하는 생성물인 1,1-difluoroethane의 분율이 90% 이상이었다. 불화된 ${\gamma}-Al_2O_3$촉매상에서 얻은 중간생성물인 vinylfluoride에 비해 원하는 물질인 1,1-difluoroethane의 비는 불화수소/아세틸렌 몰비가 높고 접촉시간이 큰 경우에서 높았고 반응온도 $210^{\circ}C$에서 최대의 값을 얻었다. The synthesis of 1,1-difluoroethane from acetylene as a function of HF/acetylene ratio, contact time and reaction temperature was studied on a fluorinated ${\gamma}-Al_2O_3$. The fluorination of ${\gamma}-Al_2O_3$ was treated with pure HF gas at high temperature. The crystallinity, the porosity, and the acid properties of the prepared samples were examined using XRD, the nitrogen adsorption, pyridine-IR and ammonia-TPD respectively. The activity was enhanced by further fluorination of alumina. The fraction of 1,1-difluoroethane was obtained above 90% at reaction temperature of about $200^{\circ}C$. The ratio of 1,1-difluoroethane to vinylfluoride over fluorinated ${\gamma}-Al_2O_3$ catalyst was increased with the mole ratio of HF/acetylene and contact time, and was found to be the highest ratio at reaction temperature of $200^{\circ}C$.
