박관희 大邱大學校 社會科學硏究所 2000 社會科學硏究 Vol.7 No.3

本 硏究에서는 먼저 OLTP(On-line Transaction Processing) 시스템인 TPS 시스템과 Data Warehouse and Data Mart를 비교 분석하였다. TPS 시스템은 기업의 기본적인 거래처리 법무를 신속·정확하게 처리하지 만은 고위 경영자의 의사결정에는 별로 지원하지 못하고 있다. 그러나 DSS인 기업 전체를 지원하는 Data Warehouse와 特定 부서에 한정된 소규모 Data Warehouse인 Data Mart는 고위 경영자의 의사결정을 지원하고 있다. Data Warehouse는 특정 주제(예: 고객, 환자, 제품 등)에 관해 기업 전반에 걸친 데이터를 한 곳으로 저장하여 경영자로 하여금 不時의 질의 및 분석을 하도록 경영 의사결정을 지원하고 있다. 그러나 Data Warehouse는 너무나 복잡하고 크기 때문에 사용자가 사용하기가 쉽지 않다. 따라서 특정 부서에 적합한 데이터를 Data Warehouse에서 선택하고 요약하여 소규모 Data Warehouse인 Data Mart를 구축하므로 최종 사용자가 데이터를 용이하게 이용하도록 한다. 최근에 개발된 Data Mart에 사용되는 사용자 도구인 OLAP(On-line Analytical Processing)는 Multidimentional 分析을 통해 사용자 정보를 容易하게 사용하게 한다. OLAP는 탐색 기법과 3차원 Cube를 분할하는 기법 等을 이용하여 사용자로 하여금 다양한 형태로 정보를 이용할 수 있게 한다. 따라서, 여러 형태로 정보를 이용하므로 경영자의 의사결정에 크게 이바지 할 수 있다. 기업들은 OLAP과 Data Mart의 사용을 통해, 경영자가 기업을 여러 측면으로 재 관찰 할 수 있어 불필요한 재고를 감소시켜 기업의 이익을 向上시키고 있다.

인체 대장암 20례와 자궁경부암 10례의 암조직을 대상으로 c-Ki-ras 유전자 codon 12와 13에서의 점돌연변이를 알아보고자 polymerase chain reaction(PCR)과 single-strand conformation polymorphism(SSCP) 검사법을 시행하였다. 대장암의 경우 20례중 9례(45%)에서, 자궁경부암의 경우 10례중 1례(10%)에서 양성으로 나왔다. 대장암에서는 codon 12에서 GGT가 TGT로의 치환이 4례로서 가장 많았으며, AGT, CGT로의 치환이 각 1례였고 codon 13에서는 GGC가 GAC로의 치환이 2례, TGC로의 치환이 1례인 것으로 나타났다. 자궁경부암의 경우 codon 12에서 GGT가 AGT로의 치환이 1례인 것으로 나타났다. In an attempt to clarify the role of genetic alteration in the genesis of human colorectal and cervical cancers, tissue specimens from 20 patients with colorectal cancer and 10 patients with cervical cancer were examined for the presence of point mutation in K-ras2 exon 1 by single strand conformation polymorphism analysis of PCR product. Exon I of c-Ki-ras2 was amplified by polymerase chain reaction(PCR) and comparison was made between the normal and mutated genes by nondenaturing polyacrylamide gel electrophoresis(PAGE) of PCR product and nucleotide sequence analysis using asymmetric PCR with direct sequencing. Genomic DNA from white blood cells were used as normal control and those from A427 cell line were used as mutated control. 1.PCR product from A427 cell line showed a distinct migration shift pattern compared to the normal control in PAGE and the direct sequencing indicated that nucleotide sequence of codon 12 was mutated from GGT to GAT. In addition, there was a loss of normal allele in A427 cell line. 2.PCR product from 9 cases(45%) out of a 20 colon cancer patients showed migration shifts in PAGE, and all of these 9 patients invariably demonstrated mutation of ras gene, either in codon 12(6 cases:30%) or 13(3 cases:15%). The base substitutions in codon 12 were: from GGT to AGT(1), CGT(1), or TGT(4). Base changes in codon 13 were from GGC to TGC(1) or GAC(2). 3.PCR product from 1 cases(10%) out of a 10 cervical cancer patients showed migration shrifts in PAGE, Invariably demonstrated mutation of ras gene in codon 12. The base substitutions was from GGT to AGT(1) TQE incidence of point mutation of c-Ki-ras in colon cancer was high, however, it was low in cervical cancer, which showed the relation of ruts gene mutation with colon cancer. PCR -SSCP analysis is a simple, rapid and efficient method of detection of point mutation, especially when dealing with multiple samples.

Bony depression in the face may occur doe to congenital failure of development trauma or excessive surgical resection. Various materials, autogenous bone, autogenous cartilage and silicone rubber have been employed for bony contour restoration. Since autogenous bone grafts become consolidated with the underlying recipient bones, the incidence of extrusion or deviation of the graft is much fewer. But they may be easily fractured at the time of carving because of their rigidity. Autogenous cartilage grafts do not require contact with the nasal bony framework, but they tend to curl and bend. Using silicone rubber is a simple and fast procedure, but the prosthesis itself is a foreign body which causes occasional foreign body reaction or exposure of the prosthesis. Therefore, the materials, which have such nature as consolidation, complete contact and convenience without complication are considered to be ideal for augmentation of the bony depression. It may be an ideal material for prevention of the complication of the implants, if a new bone formation at the gratted periosteum wrapping the silicone rubber implants develops. To confirm the possibility, biological test with dogs was initiated. Six samples of periosteum and fascia wrapping the silicone rubber implants, respectively were collected from 9dogs at 8, 16 and 24 weeks. Grossly, difference between translucent periosteum and whitish fascia was noticeable at 8 weeks after implantation. However, it is difficult to distinguish between fascia and periosteum at 24 weeks. Histologically, fibrous capsule developed at 8 weeks and there was a marked thickening at 24 weeks on both periosteum and fascia. At one of 6 samples of 24 weeks periosteum, wrapping the silicone rubber implant, formed a new bone. In conclusion it is possible for the grafted periosteum wrapping the silicone rubber implants to make a new bone. Therefore the periosteum and fascia wrapping the silicone rubber are well taken at the recipient site. Also, they play a good role of barrier against exposure of implant. Especially the periosteum is better than the fascia, because of its bony formation and easier obtaining
