  • To realize a high integrated Flash memory utilizing SONOS memory devices, the NOR type 1TC(one Transistor Cell) SONOS Flash arrays are fabricated and characterized. This SONOS Flash arrays with common source lines are designed and fabricated by conventional 0.35$\mu\textrm{m}$ CMOS process. The thickness of ONO for memory cell is tunnel oxide of 34${\AA}$, nitride of 73${\AA}$ and blocking oxide of 34${\AA}$. To investigate operating characteristics, CHEI(Channel Hot Electron Injection) method and Bit line erase method are selected as the write operation and the erase method, respectively. The disturbance characteristics according to the write/erase/read cycling are also examined. The degradation characteristics are investigated and then the reliability of SONOS flash memory is guaranteed.

  • The purpose of this study was to investigate the effect of dietary Morus alba L.(Bong-ip, B), Glycyrrhizae glabra(Gam-chei, C), Pinus densiflora(Sol-lp, S) and Angelica gigas(Dang-gi, D)powder on serum composition in rats(Sprague-Dawley male rats, 100-110g). Serum TG(triglyceride, p<0.01), total cholesterol, glucose, total protein, albumin, GGT$({\gamma}-glutamyl$ transferase, p<0.05) were significantly increased D group than that of nomal and other groups, but UA(uric acid, p<0.05) was significantly decreased, and C group(p<0.05) was significantly increased. but C group of urine(p<0.05) was significantly decreased. Also, B and S groups(p<0.05) of BUN(blood urea nitrogen), S group(p<0.05) of ALP(alkaline phosphokinase, Band C(p<0.05) of CPK(creatinine phosphokinsae, p<0.05) were significantly increased. B, S and C groups were better than D group for lipid metabolism, and pretection to liver. Also, B and C groups of glucose were same as normal diet, so Morus alba L. was good food for lipid metabolism and hypoglycemic effect.

  • Anal Therapy is taken valid compound of herb med and has many kinds of treatments. As one of the anal therapy, retention enema is most common and useful way. This study was performed in order to literatural basements of clinical treatments. we had cleared manifest about the origin and literatural basement of anal therapy, methods of management, classification of indication, clinical application and so forth. The results were summerised as follows. 1. It explained relationships between anus and Ojang-yukbu(五臟六腑), Sibie-geongmaek(十二經脈). But in fact the origin of anal therapy is Milgeon-dobub(蜜煎導法) and Jedamjib-dobub(猪膽汁導法) in Sanghan-jabbyungron(傷寒雜病論) of Han Dynasty. 2. The effect of anal therapy can be reached to the destination through theory of the organism which is called Jung-chei theory(整體論) and local medical action. We can find a little in Naegeong(內經), which is basement of Hang-jang therapy. 3. Anal Therapy have Kwanjaogbub(灌腸法), Guhangbub(灸肛法), Dohangbub(塗肛法), Hoonhangbub(熏肛法), Saekhangbub(塞肛法), Youkhangbub(浴肛法), Jwajeombub(坐점法) e.t.c. 4. Anal Therapy is available when person can't taken by mouth. Its benefits are fast effect and low side effect about liver because it is not taken trough liver mostly. 5. Anal Therapy has been used for the treatment of diseases such as stroke, high fever, pneumonia, ulcerative colitis, prostatitis, renal failure, pelvic inflammation. cancer and so on.

  • 최근의 인터넷의 급속한 발전에 힘입어 멀티미디어 데이터를 인터넷을 통해 서비스해 주는 스트리밍 서비스가 활성화가 되고 있다. 스트리밍 서버는 서비스를 요청한 클라이언트에게 일정한 데이터 전송률로 서비스를 하게 되는데, 이때 시간측정 함수를 매우 빈번히 사용하게 된다. 본 논문은 시간 측정함수를 가상 시스템 호출 기법을 이용해 성능을 향상 시킬 수 있음을 보여준다.

  • 프로세스와 디스크 입출력 속도를 비교해보면, 디스크 입출력의 속도가 휠씬 더 느리다. 따라서 디스크 입출력은 현재의 컴퓨팅 환경에서 병목현상이 되고있다. PFSL(Parallel File System for Linux)은 이런 문제를 해결하기 위한 클러스터링 환경의 병렬 파일 시스템이다. PFSL은 리눅스 머신 상에서 POSIX 스레드 라이브러리를 이용하여 멀티 스레드로 수행된다. 이 논문에서는 PFSL의 성능을 개선하기 위해 클러스터 환경의 작업 부하에 적합하도록 설계한 이중 캐쉬 구조를 소개하고자 한다.
