Embedded system is a large part in modern society. Most people, however, do not know about embedded systems. The need for training related to embedded systems is increasing because embedded system technology is a core technology of the country these days. In this paper, we understand embedded systems easily using LEGO Mindstorms NXT that is used in the actual embedded system education. In addition, we perform the simulation based on DEVS formalism and SES framework as a part of the knowledge related with embedded systems. Measuring the time and probability for completing the track by several algorithms of line tracer, we determine the speed and accuracy of the algorithms. We adopt the best algorithm through the simulation results, and we make line tracer with the algorithm.

Gastric hepatoid adenocarcinoma is a special type of gastric carcinoma, which produces AFP. We report a case of an metastatic gastric hepatoid adenocarcinoma mistaken for primary hepatocellular carcinoma (HCC). A 72 year-old woman was transferred to our hospital for treatment of the hepatic mass. She underwent subtotal gastrectomy for gastric cancer 2 years ago. A year ago, she was diagnosed with hepatic mass and treated with transhepatic chemoembolization under the suspicion of primary HCC in other hospital. The hepatic mass looked like primary HCC on CT, and serum AFP was elevated to 18,735 IU/mL. We did the transhepatic mass biopsy and compared it to the histology of the previous gastric cancer, The results of immunohistochemical staining between them was coincident, and so it was diagnosed as a hepatic metastasis of gastric hepatoid adenocarcinoma.

Isolated CCTGA 환자는 전체 CCTGA 환자의 약 1% 가량으로 매우 드문 것으로 알려져 있는데, 이들은 방실 차단, 전신 순환 방실 판막 역류 등 다른 기능적 이상이 나타날 때까지 무증상으로 지내는 경우가 많다. 저자들은 14년 동안 무증상으로 지내던 isolated CCTGA 환자가 호흡 곤란과 어지러움증으로 내원해 완전 방실 차단 보여 영구 심박동기를 이식해 치료한 1예를 경험하였기에 보고하는 바이다. Patients with isolated congenitally corrected transposition of the great arteries (CCTGA) comprise 1% of all CCTGA patients. They are usually asymptomatic until functional abnormalities such as atrioventricular block or systemic atrioventricular valve regurgitation become complicated. We report here a case of a 33 year-old man with isolated CCTGA and complete AV block that underwent implantation of a permanent pacemaker using endocardial leads. During a 12 month follow-up period, no symptoms developed and lead-related parameters have been stable. (Korean J Med 72:311-314, 2007)

Rituximab is a chimeric monoclonal antibody for human B lymphocyte subset CD20 and has recently been used for treatment of autoimmune disease such as rheumatoid arthritis and systemic lupus erythematosus (SLE). We report the experiences of rituximab treatment in two patients with severe SLE. The first case is 16-year-old female patient with hemolytic anemia, thrombocytopenia and acute renal failure due to aggravation of lupus nephritis, and the second case is 30-year-old female pregnant patient with diffuse alveolar hemorrhage after preterm premature rupture of fetal membranes. All two patients responded to rituximab and maintained symptom free state.

A 49-year-old female was admitted to our hospital for acute pancreatitis. The abdomen CT scan incidentally showed midline liver with hepatomegaly, centrally located gallbladder, pancreas truncation, right sided small bowel, left sided large bowel, interruption of the inferior vena cava with azygos continuation, preduodenal portal vein, and multiple spleens in the left upper quadrant. In MRCP, the head of pancreas was enlarged and short main pancreatic duct without accessory duct was showed. EUS revealed enlarged ventral pancreas with a main pancreatic duct of normal caliber, absence of the accessory pancreatic duct and the dorsal pancreas. She was diagnosed as polysplenia syndrome with agenesis of dorsal pancreas. It is a rare congenital anomaly frequently associated with various visceral anomalies including multiple spleens, impaired visceral lateralization, congenital heart diseases, gastrointestinal abnormalities and azygos continuation of the inferior vena cava. We report a case of polysplenia syndrome with agenesis of dorsal pancreas presenting acute pancreatitis. (Korean J Gastroenterol 2012;60:47-51)
