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.

Through the rapid development of our Information Communication engineering during the past thirty years, our Information Communication 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 internation competition more effectively, sufficient supply of manpower skilled in Informational Communication 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 envelopment in Information Communication engineering.

Podocyte apoptosis induced by hyperglycemia is considered a critical factor in the development of diabetic nephropathy. Recent studies have implicated Notch signaling in podocyte apoptosis; however, its regulatory mechanisms are not fully understood. In this study. we found that high-glucose treatment increased Notchl and jagged-l expression, the transcriptional activity of Hes. and podocyte apoptosis, and decreased the expression of coactivator-associated arginine methyltransferase 1 (CARMI) in rat podocytes. Transient transfection of CARMI reversed high-glucose-induced Notchl expression. the transcriptional activity of Hes, and podocyte apoptosis. Moreover. the silendng of CARMI using siRNA increased Notchl expression. the transctiptional activity of Hes, and podocyte apoptosis. However, the Glu266-mediated enzymatic activity of CARMI was not necessary for Notch signaling activation and podocyte apoptosis. Here, we demonstrate that AMP-activated protein kinase alpha (AMPKa) and cannabinoid receptor 1 (CB,R) are regulated by CARMI and that high-glucose-induced podocyte apoptosis is mediated by a CARMl-AMPKa-Notchl-CB,R signaling axis. We also show that highglucose-induced CARMI downregulation is due to ubiquitination-dependent CARMI degradation. Finally, we demonstrate that CARMI expression in podocytes was diminished in rats with streptozotocin-induced diabetes compared to vehicle-treated rats. Together, our data provide evidence that ubiquitination-dependent CARMI degradation in podocytes in diabetes promotes podocyte apoptosis via Notch 1 activation. Strategies to preserve CARMI expression or reduce the enzymatic activity of a ubiquitin ligase specific for CARMI could be used to prevent podocyte loss in diabetic nephropathy. ⓒ2014 Published by Elsevier lnc.
