Nanostructured carbon materials are potentially of great technological interest for the development of electronic, catalytic and hydrogen-storage systems. Here we describe a general strategy for the synthesis of highly ordered, rigid arrays of nanoporous carbon having uniform but tunable diameters (typically 6 nanometres inside and 9 nanometres outside).(More)
As the Unified Modeling Language (UML) becomes an industrial standard for object-oriented software development, many system models have been specified in UML notation. A system can be described in terms of the functional view through the use case model, the static view through the class model, and the dynamic view through activity or sequence model. In(More)
Between February 1997 and December 2001, 311 adult-to-adult living donor liver transplants (A-A LDLTs) were performed at the Asan Medical Center for patients above 20 years of age. Indications for A-A LDLT were: chronic hepatitis B (203), chronic hepatitis C (5), hepatocellular carcinoma (64), alcoholic cirrhosis (9), cryptogenic cirrhosis (4), secondary(More)
Intussusception following gastric surgery is a rare postoperative complication. It may develop in clinical situations following gastroenterostomy, Billroth II gastric surgery with or without Braun anastomosis, or Roux-en-Y gastrojejunostomy. The patients may present with either an acute surgical emergency or with a chronic, relapsing form. The mortality may(More)
The INK4A locus encodes two tumor suppressor genes, p16(INK4A) and p14(ARF), transcribed using alternative exons 1alpha or 1beta spliced onto the same exons 2 and 3. Both p16(INK4A) and p14(ARF) are capable of inhibiting the cell-cycle progression, albeit in different manner; p16(INK4A) is phosphorylation of retinoblastoma (pRB) dependent while p14(ARF) is(More)
Rib tuberculosis is an extremely rare condition with the incidence not exceeding 3 percent of all skeletal tuberculosis. The authors experienced a recalcitrant case of pulmonary tuberculosis accompanied by chest wall cold abscesses involving ribs recurring at a new site in approximately 10 months despite of medical and surgical treatment. The patient has(More)
PURPOSE The purpose of our study was to determine specific CT findings of tuberculous pneumonia presenting as segmental or lobar consolidation along with a pathologic review of specimens with similar radiographic patterns. METHOD CT findings of 45 cases of proven tuberculous pneumonia and 21 proven nontuberculous pneumonia were compared. Pathologic(More)
BACKGROUND In an effort to expand the deceased donor pool, transplant centers have accepted expanded-criteria donors as appropriate for many of the patients in the deceased donor pool. We investigated expanded-criteria deceased donor kidney transplantation and compared the outcomes of kidney transplantation according to donor types. METHODS We(More)
By increasing the requirement of reliable and accurate sensor information, the integration of multiple sensors has gained attention. Especially, the fusion of a LIDAR(Light Detection And Ranging) and a camera is one of the sensor combination broadly used because it provides the complementary and redundant information. Many existing calibration approaches(More)
