본 논문은 RISC CPU 인 Intel StrongARM SA-1100 을 기반으로 하는 실시간(Real-Time) 운영체제를 설계한 내용을 설명하고 있다. 본 논문에서 구현된 운영체제는 태스크들이 우선순위 기반으로 처리되는 선점형 스케줄링 방식을 채택함으로써 실시간 운영체제의 주요 특정인 시간 결정성(determinism)을 보장하도록 하였다. Intel StrongARM SA-1100 은 고성능(High Performance), 저전력(Low Power)의 장점 때문에 모바일(Mobil) 환경에서 많이 사용되고 있다. 본 논문은 Intel StrongARM SA-1100 CPU를 타겟으로 시간 결정성이 보장되도록 멀티 태스킹(Multitasking)과 ITC(InterTasking Communication)를 설계하고 구현한 내용에 대해 설명하고 있다.

Pseudomyxoma peritonei (PMP) is a rare clinical syndrome characterized by profuse jelatinous materials in the abdominal cavity and pelvis with mucinous implants on the peritoneal surface. There are some studies for serum tumor markers, including carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9) and carbohydrate antigen 125 (CA125), to assess the risk of recurrence following cytoreductive surgery and intraperitoneal chemotherapy. However, rare cases were reported about recurrence with increasing serum CEA levels. Herein, we report a case of recurrence of PMP according to serially elevated serum CEA.

The gastrointestinal tract is the most common site of extra-nodal non-Hodgkin lymphoma. However, the incidence of primary rectal lymphoma is extremely rare. Among the primary gastrointestinal lymphomas, follicular lymphoma has been described as a rare disease. It is difficult to diagnose rectal lymphoma due to its variable growth patterns and inadequate biopsies. Majority of patients with rectal lymphoma have non-specific symptoms or negative biopsies, often delaying the diagnosis. Our patient is a 62-year-old female. Two sessile and smooth subepithelial lesions with a yellowish normal mucosa were found on a screening colonoscopy. The initial mucosal biopsy finding was chronic inflammation, but we were highly suspicion of malignancy; we performed an endoscopic mucosal resection. Herein, we present a rare case of rectal follicular lymphoma diagnosed by endoscopic mucosal resection with a literature review. (Korean J Gastroenterol 2017;69:139-142)
