Tissue engineering has emerged as a promising approach to treat the loss or failure of a human tissue or organ without the limitation of current therapies. In the tissue engineering approach, the patients could be treated with new tissues or orgarfs reconstructed with transplanted cells. The cells for tissue engineering could be somatic cells derived from the patients themselves, other individuals, or animals. Another valuable cell source would be stem cells. Embryonic stem cells retain the pluripotency to differentiate into every cell type of human organs, but ethical issues remain problematic. Adult stem cells remove the problems of ethical issues and immune rejection, but have limitation in differentiation into all ranges of tissue-specific cell types. Engineering tissues with stem cells and biomaterials may be an alternative to current suboptimal therapies for treatment of malfunction or loss of human tissue or organ.
밀착결합된 MIMD 시스템에서 지원되는 세마포어 형식의 동기화 기법에 관한 연구
김병수 建陽大學校 1992 建陽論叢 Vol.- No.1
봄 논문에서는 MIMD 시스템에서의 기존의 동기화 기법들과는 달리 종속의 성질에 따라 적절한 동기화 명령어를 문장 사이에 삽입하는 동기화 기법에 관하여 논하였으며, 가변종속에서의 동기화 기법도 아울러 논하였다. 또한 동기화명령어들의 효율적인 제거 방법을 개발하여 기존의 CPG 방법과 비교, 월등한 성능향상을 보였다.

Small bowel leiomyoma is a rare tumor which may occur wherever smooth muscle is present. The small bowel is the most common site and it makes up 20~30% of all benign small intestinal neoplasms. A spectrum of symptoms are common ranging from nausea, vomiting, abdominal pain, to massive intestinal bleeding. Bleeding is the most common symptom and is usually gross and recurrent. Occasionally it may be life threatening. But, the most serious problem is both the absence of specific clinical symptoms, and the difficulties shown in radiological diagnostics of the small bowel. If conventional diagnostic methods fail to reveal any positive findings for gastrointestinal bleeding, the diagnosis of intestinal leiomyoma should be suspected and an SMA angiography shoud be performed. The angiographic criteria of small bowel leiomyoma is very characteristic. We present a case of leiomyoma with considerable and prolonged gastrointestinal bleeding, which was diagnosed by angiography. A 61-year old woman was admitted with a history of melena over the last 10 days. An SMA angiography showed a hypervascular mass with a diameter of 3×3cm. A segmental resection was performed under the impression of the gastrointestinal bleeding due to leiomyoma of the small bowel. Microscopic examination of the lesion shows interlacing or whorl bundles of spindle shaped ces and no mitosis.
