Acinar cell carcinoma is a rare tumor that represents 1~2% of al1 pancreatic cancers. Clinical and radiologic findings are inconclusive in this disease Acinar cell carcinoma is characterized by rapid progression and early metastasis, which lead to its poor prognosis. A 41-year-o1d man was admitted to our hospital for abdominal pain. Abdominal computed tomography (CT) and positron emission tomography-computed tomography (PET-CT) showed a splenic mass, which was being invaded by a pancreatic tail mass and which had increased ^(18)F-fluorodeoxyglucose (FDG) uptake Primary radical distal pancreatectomy and splenectomy were performed. Pathologic findings revealed an acinar cell carcinoma of the Pancreas The patient underwent a total gastrectomy three months later because of gastric recurrence Four months later, multiple hepatic metastases were discovered, and the patient underwent a left hepatectomy During treatment with capecitabine, there was no evidence of tumor progression for 14 months. We report a case of metastatic pancreatic acinar cell carcinoma, which did not progress for an extended period while the patient was being treated with capecitabme.

The purpose of this study was to find the way of treatment and prevention the stroke by Sangsang constitutional medical therapy. I came to get some conclusions after considering literatures of 《Dongyi Suse Bowon》and the conclusions as follows. 1. In 《Dongyi Suse Bowon》the stroke of Soumin is caused by 'Interior cold disease'. When 'Interior Yin' can not descend, the disease arise. In this case Lee Je-ma used 'Sohabhyang-won(蘇合香元)' , 'Chulaek-su(鐵液水)' . 2. The stroke of Soyangin is caused by 'Interior heat disease'. When the hot Qi of stomach and spleen is blocked, the disease arise. In this case Lee Je-ma used 'Dokhwal-jihwang-tang(獨活地黃湯)' , 'Jihwang-baekho-tang(地黃白虎湯)'. 3. The stroke of Taeumin is caused by 'Dry and heat disease'. When the heat of liver and the dryness of lung is excessive, the disease arise. In this case Lee Je-ma treated with 'Woohwang-chungsim-hwan(牛黃淸心丸)'. 'Wonji-sukchangpo-tang(遠志石菖浦湯)' , and 'Kwache-san(瓜帝散)' etc. Above results indicate that not only taking medicine but also filling up the Healthy energy(保命之王) is important to treat stroke.

국내 데이터베이스 구축 시장은 작년 기준으로 3조 6,633억원 규모로 추정된다. 데이터베이스 산업의 지속적인 성장과 맞물려, 데이터 마이그레이션의 중요성도 날로 높아지고 있다. 고객 위치를 찾아주는 g-CRM이나 고객에게 상품을 추천하는 맞춤 설계 기능 등은 모두 고객 데이터베이스, 상품 데이터베이스, 지리정보 데이터베이스 등이 결합되어야 구현 가능한 서비스들이다. 스마트 비즈니스의 핵심 인프라도 통합되고 완전하며 신뢰할 수 있는 데이터베이스라고 할 수 있다. 이러한 데이터베이스의 중요성에도 불구하고, 데이터 마이그레이션 및 통합 과정의 효율적인 수행 방안이나 데이터 검증 방법에 대하여는 구체적인 연구가 부족한 실정이다. 본 연구에서는 다양한 타입으로 존재하는 과학기술분야 콘텐츠들을 대상으로 데이터 마이그레이션을 위한 모델을 설계하였고, 모델을 기반으로 실제 데이터 마이그레이션 작업을 수행한 결과를 제시하였다. 아울러 데이터 마이그레이션 결과에 대한 검증을 위해 데이터베이스의 완전성, 데이터값의 일관성, 관계의 일관성을 검증하였고, ANSI/ASQ Z1.4-2003에서 제시된 샘플링 검사 기법도 적용하였다. 결과적으로 모델 수립에 의한 체계적인 데이터 마이그레이션 수행은 데이터베이스 정합성 및 데이터값의 정확성에 영향을 미치고, 고품질의 데이터베이스를 유지하기 위한 필수 요소라 할 수 있다. The domestic market of database in Korea is estimated to be over 3.663 trillion won. The data migration is getting to be more important along with the continuous growth of the database industry. g-CRM and private recommending function are examples of the service that can be given through coupling among customer database, product database, geographic information database, and others. The core infrastructure is also the database which is integrated, perfect, and reliable. There are not enough researches on efficient way of data migration and integrating process and investigation of migrated data though trends of database in IT environment as above. In connection with this issue, we have made a model for data migration on scientific and technological contents and suggest the result of data migration process adapting that model. In addition, we verified migration's exhaustiveness, migration's consistency, and migration's coherence for investigation of migrated data and database. From the result, we conclude data migration based on proper model has a significant influence on the database consistency and the data values correctness and is essential to maintain high qualified database.
