In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

For the comparative analysis of the blood lactate concentration of scuba diver according to change from safety zone to sea and of the change of amount of CPK while scuba diving, C university measured the blood lactate concentration and amount of CPK against middle level and debutant scuba divers. As a result, the following differences ranging from 1) to 4) were found in divers by each factor. 1) The blood lactate concentration and CPK amount of clivers out of safety zone were 2.68 and 225.70 respectively. They were out of sea area 3.70 and 337.90 respectively. The change in blood lactate concentration out of safety zone was higher than out of sea area and CPK amount was found higher from safety zone than from sea area. But to find what differences between the blood lactate concentration and CPK amount between safety zone and sea area, I implemented independent T-test against average differences, the significance of blood lactate was .092 while that of CPK amount was .312. Therefore, the blood lactate concentration and CPK amount were not significant in safety zone and sea area. In other words, there is no significant differences in change of blood lactate concentration and CPK amount of clivers in change from safety zone to sea area. 2) The average blood lactate concentration and CPK amount in 30 minutes after going out of safety zone were 2.04 and 259,80 respectively and the average blood lactate concentration and CPK amount in 30 minutes after going out of sea area zone were 2.28 and 377.60 respectively. The blood lactate concentration and CPK amount during 30-min rest after going out of safety zone were found higher in sea area. But to find what differences between the blood lactate concentration and CPK amount between safety zone and sea area in 30 minutes out of waters, I implemented independent T-test against average differences, the significance of blood lactate was .592 while that of CPK amount was .307. Therefore, the blood lactate concentration and CPK amount after 30 minutes were not significant in safety zone and sea area. In other words, there is no significant differences in change of blood lactate concentration and CPK amount of divers in change from safety zone to sea area. 3) During stabilization of divers, the average blood lactate concentration and CPK amount were 2.66 and 290.80 respectively, the average blood lactate concentration and CPK amount after going out of safety zone were 2.68 and 257.70 respectively and the average blood lactate concentration and CPK amount during 30 minutes after going out of safety zone were 2.04 and 259.80 respectively and the average blood lactate concentration and CPK amount after going out of sea area were 3.70 and 377.90 respectively and the average blood lactate concentration and CPK amount during 30 minutes after going out of sea area were 2.28 and 377.60 respectively. From the above results of higher concentration and CPK of divers going out of sea area, the sea environment gives more impact on divers. 4) The conclusion of each factor and rest is as follows: The significance of blood lactate concentration and CPK amount during stabilization and out of safety zone were .961 and .666 respectively. Therefore, there is no significance in divers resting and going out of safety zone. The significance of blood lactate concentration and CPK amount during 30 minutes of rest and out of safety zone were .083 and .683 respectively. Therefore, there is no significance during 30 minutes of divers resting and going out of safety zone. The significance of blood lactate concentration and CPK amount during stabilization and out of sea area were .035 and .514 respectively. Therefore, there is no significance in clivers resting and going out of sea area. The significance of blood lactate concentration and CPK amount during 30 minutes of rest and out of sea area were .292 and .507 respectively. Therefore, there is no significance during 30 minutes of clivers resting and going out of sea area.

대장 지방종은 주로 우측 결장에 호발하고 특히 회맹판 부위와 맹장 부위에 호발한다. 또한 50~60대에 빈도가 높고 증상이 있는 환자에서 장중첩증이 높게는 40~50%에서 보고되고 있어 성인 장중첩증의 원인으로 중요한 비중을 차지한다. 특히 성인 장중첩증 및 장폐쇄의 중요 원인인 악성 종양과 임상 양상이 유사하여 감별진단이 중요하다. 저자들은 반복적인 복통을 주소로 내원한 환자에서 맹장의 4×5㎝의 점막하 지방종이 말단 회장부위와 반복적인 장중첩중이 발생했던 1례를 부분 절제술로 치료하여 양호한 임상 경과를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. Lipomas are one of the most common benign nonepithelial tumors of the colon which are often detected incidentally by radiologic investigation or on operation. These tumors are usually without specific symptoms. Colonic lipomas occur most often in the right colon, particularly in the ileocecal valve and the cecum. Most patients are asymptomatic. but tumors larger than 2 cm tend to produce a change in bowel habit. abdominal pain. rectorrhagia and complications including luminal obstruction or intestinal intussusception. Diagnosis can be made by colonoscopy abdominal CT. MRI, or barium enema. We report a case of lipoma of the cecum that originated in the submucosa and presented as a intussusception in a 50-year-old woman with a brief review of the literature.

This study was undertaken for the clinical evaluation and statistical analysis on the 38 cases of placenta previa who were admitted and treated from March 1, 1988 to Feb. 28, 1991. The results were as follows : 1. The incidence of placenta previa was one per 53 deliveries or 1.90% 2. There were 57.9 % total placenta previa, 21.1 % partial placenta previa, 13.1 % low-lying placenta previa and 7.9% marginal placenta previa. 3. Placenta previa has occured more often in multipara (63.2%) than primigravida 4. More than one-third (38.8%) cases of placenta previa had delayed admission until labor occured for some time following vaginal spotting has first time been noticed. More instructive prenatal education should be emphasized 5. Lower segment transverse section rate was 63.2%, classical cesarean section rate was 15.8% and cesarean hysterectomy was 9.8%. The rest of them were treated by vaginal deliveries of 5 cases(13.2%) 6. The perinatal loss associated with placenta previa was considered still higher : the premature death was 15.8% and term death was 2.6%. The problem of prevention of prematurity still remains to be studied. 7. There was no maternal mortality in our study

고속의 실시간 MPEG-2/H.264 transcoding 구조 제안

홍용택,이경호,김진상,조원경 경희-다반 ASIC 설계교육센터 2006 경희-다반 ASIC센터 논문집 Vol.7 No.-

H.264 비디오 코딩 표준은 기존 비디오 코딩 표준에 비해 뛰어난 압축부호화 효율로 인해 차세대 비디오 표준으로 각광받고 있으며 H.264가 가진 잠재적인 영향력 때문에 오늘날 디지털 비디오 시스템의 주를 이루고 있는 MPEG-2 시스템을 대체할 것으로 보여진다. 현재 MPEG-2 시스템이 광범위하게 자리 잡고 있기 때문에 H.264 시스템으로의 완전한 이동은 다소 시간이 걸릴 것으로 예상되고, 따라서 트랜스코딩 기술이 중요하게 대두되고 있다. 트렌스코더는 디코더와 인코더를 포함한 구조이기 때문에 매우 많은 연산량이 요구되며 그 복잡도를 줄이는 것이 중요하다. 본 논문에서는 디코딩 과정에서 추출된 정보를 인코딩 과정에 재사용함으로써 복잡도를 줄이도록 하였고, 또한 H.264에서 연산량이 많은 부분들을 여러 가지 알고리즘을 통해 복잡도를 줄임으로써 보다 빠른 속도로 동작이 가능한 트랜스코더 구조를 제안하였다.
