CORBA, which is a standard base of distributed object in distributed computing environment, suggests the method for clearly creating the demand for object defined on OMG and receiving it. Although CORBA appeared as the standard of distributed object and has played an important role in operating distributed object between different computer systems, distributed object computing has such fundamental problem as great demand by many clients an3 Server and the overload of network. CORBA is middle-ware technology to develop one distributed application program by connecting separately-developed distributed object in various platforms which are connected in, open communication network. With expansion of distributed application software scale and complex interface between distributed objects, this study defines object as group in the concept of aggregate in order to control efficiently and to be controlled as group by grouping multi-arranged object and suggests group object model in the side of controller for efficient control of distributed object.
Evans syndrome is defined as a simultaneous or sequential occurrence of autoimmune hemolytic anemia and autoimmune thrombocytopenia. Autoimmune hemolytic anemia (AIHA) is usually induced by IgG warm autoantibody or cold-active IgM antibodies reacting specifically with antigens associated with a patient's RBC. AIHA is a fairly uncommon disorder, with estimates of the incidence at 1 to 3 cases per 100,000 per year. Mixed-type AIHA is a relatively uncommon form of AIHA, with studies noting the incidence of 7-8% among cases of AIHA. We experienced a patient, 46-year-old woman who was diagnosed having a very rare clinical presentation of mixed warm and cold antibody mediated Evans syndrome. She was treated with corticosteroid therapy only and has been maintaining a complete response for 15 weeks. 저자들은 혼합형의 자가면역성 용혈성 빈혈과 자가면역성 혈소판 감소증이 동시에 발생한 혼합형 Evans 증후군으로 진단하고 스테로이드 요법 후 혈액학적으로 회복된 상태로 15주가 지난 현재 steroid 5 mg/일 까지 감량한 상태에서 추적 관찰 치료중인 46세 여자 환자를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.
The 3-D shape use to effect of movie, animation, industrial design, medical treatment service, education, engineering etc... But it is not easy to make 3-D shape from the information of 2-D image. There are two methods in restoring 3-D video image through 2-D image; First the method of using a laser; Second, the method of acquiring 3-D image through stereo vision. Instead of doing two methods with many difficulties, I study the method of simple 3-D image in this research paper. We present here a simple and efficient method, called direct calibration, which does not require any equations at all. The direct calibration procedure builds a lookup table(LUT) image and 3-D coordinates by a real 3-D triangulation system. The LUT is built by measuring the image coordinates of a grid of known 3-D points, and recording both image and world coordinates for each point; the depth values of all other visible points are obtained by interpolation.

Clinical strains of Mycobacterium tuberculosis, M. terrae complex, M. gordonae, M. avium-intracellulae complex, and M. fortuitum from Korean patients were isolated and analyzed by comparing large restriction fragment (LRF) patterns produced by digestion of genomic DNA with infrequent-cutting endonucleases like AsnI and XbaI. and pulsed-field gel electrophoresis (PFGE). Three M. tuberculosis, two M. terrae complex, two M. gordonae, two M. avium-intracellulae complex, and two M. fortuitum strains were compared by using AsnI and XbaI. and this allowed easy visual separation of all epidemiologically unrelated strains. PFGE exhibits different DNA restriction patterns which are easy to compare. Genome size of the strains roughly ranged from 3020 to 3335 kb. The LRF patterns are useful for epidemiologic studies of tuberculosis with regard to drug resistance.
XML과 데이터베이스간의 자료 변환의 원리는 XML과 데이터베이스 간 매칭의 원리로 이루어진다. SQL Server의 데이터에 접근하기 위한 방법은 URL에 SQL 쿼리를 지정하는 방법과 template 파일을 이용하는 방법이 있다. MS-SQL 서버는 OpenXML 기능을 이용하여 기존의 관계형 데이터베이스에 대해 SQL 합리를 실행한 결과를 XML 문서로 변환한다. 즉 OpenXML은 노드 트리를 생성한 후에 XML 문서의 로우셋 데이터를 반환하고, XML 데이터를 관계형 형식으로 얻게 한다. XML 데이터를 데이터베이스 데이터로 삽입하기 위해서는 sp_xml_preparedocument 프로시져를 사용하여, XML 문서를 파성해 데이터를 추출한 후, 그 문서의 노드 구조를 메모리의 트라 구조로 매핑해서 데이터베이스 테이블에 저장하게 된다. 결국 XML과 데이터베이스간의 자료 변환의 원리는 XML과 데이터베이스간 매칭의 원리로 이루어진다. 본 논문에서는 매핑 원리를 채시한 후, SQL Server의 지원하에 두 자료간의 변환을 구현해 보임으로서 자료의 확장성과 효율성 및 다양한 효과를 가져올 수 있음을 제시하고 있다.<br/> The data transformation between XML and Relation Database is made through the principle of mapping bewtween them, There are two ways to access SQL Server, one is to assign SQL query to 001 and the other is to use template file. MS-SQL server takes advantage of OpenXML function to transform the results of executing SQL query into XML documents, That is, OpenXML first makes node tree and then transforms row set data of XML documents into XML data of relation type. In order to insert XML data into database data, data is extracted from parsing XML documents using sp_xml_preparedocument procedure, and then the document structure is mapped into tree structure and stored in a table of database, Consequently, Data transformation between XML and Relation Database is made through mapping between them. This article proposes the principle of mapping between XML and Relation Database and then shows the implementation of transformation between them so that it introduces the possibilty of bringing the extension and efficiency of data and various effects.<br/>
Through the rapid development of our electronic engineering during the past thirty years, our electronic industry has not only played a chief role in the economic development of our country, but also greatly enhanced our position in the world market. But to confront the international competition more effectively, sufficient supply of manpower skilled in electronic technology is seriously required, and to meet this requirement, it is thought very necessary to examine the demand and supply of the manpower and their education. This study is aimed to predict the future demand of skilled manpower and to suggest a desirable educational system for them by investigating the process of the past development in electronic engineering.
ICT를 활용한 교육은 전세계적인 추세이다. 지금은 자기 자신에게 필요한 가치 있는 지식으로 재구성하고 창의적인 학습이 필요한 시기로서 ICT를 교육현장에서 활용하고자 하는 노력이 급증하고 있다. 본 논문에서는 ICT를 이용하여 교수-학습을 효율화하는 방법과 대학에서 ICT활용에 관해서 기술하였다. The effort to make use of ICT in the classroom is increasing dramatically to meet the requirements of being creative and restructuring knowledge for an individual student. In this paper. methods to enhance teaching and learning using ICT and methods to utilize ICT in the university are proposed.
