A 6 year experience with the bileaflet St. Jude Medical valve is reported. Between Feb. 1986 and Dec. 1992, 68 patients received 87 such valves[36 mitral, 13 aortic, and 19 double mitral-aortic valve replacements]. The results are summarized as follows 1. There were 35 male and 33 female patients ranging in age from 17 to 55 years the mean age of 35.3 $\pm$ 9.7 years. 2. The mean aortic clamp time[ACT] of the MVR, AVR and DVR groups were 91.5$\pm$16.4, 117.2$\pm$28.7 and 165.5$\pm$24.1 minutes. The mean total bypass time [TBT] of the MVR, AVR and DVR groups were 112.8$\pm$19.5, 134.7$\pm$31.4 and 192.2$\pm$28.5 minutes. 3. Eighty seven valves were used [55 mitral site, 32 aortic site]. 31mm[20], 33mm[15], 29mm[15], 27mm[2], 25mm[2] and 35mm[1] were used in mitral site and 23mm[13], 21mm[8], 19mm[7] and 25mm[4] were used in the aortic site. In the DVR, there were valve combinations such as 4 cases of M[29mm]-A[19mm], 4 of M[31mm]-A[23mm], 3 of M[33mm]-A[23mm] and others. 4. Preoperative NYHA functional classes were II [3 cases], III [46 cases], IV[19 cases] and improved to I [52 cases] and Il [13 cases] postoperatively. 5 Early postoperative complications were occurred in 15 cases[2Z.l%] and there were LOS in 5 cases[7.4%], arrythmia [3 cases], wound infection [2 cases], hepatitis [2 cases], sudden cardiac arrest [2 cases] and postoperative bleeding [1 case]. The early hospital death was occurred in 3 cases[4.4%] with LOS [1 case] and sudden cardiac arrest [2 cases]. 6. Mean follow-up time of survival cases[65 cases] was 31.3$\pm$21.9 months and the total follow-up time was 169.8 patient-years. Late postoperative complications were occurred in 4 cases[2 thromboembolism, 1 paravalvular leak, 1 thromboembolism br paravalvular leak, 1 valve endocarditis] with the occurrence rate as 2.35% per patient-years. Reoperation was performed in 2 cases [1 paravalvular leak, 1 left atrial thrombus] and there was one [1.5%] late valve related death. Therefore the 6 year complication free rate was 90.6% and 6 year actuarial survival rate was 98.3$\pm$1.7%. On the basis of this experience and the results, SJMvalve appears to be one of the best performing mechanical prosthesis currently available, in terms of both hemodynamics and lower complications with warfarin antioagulation.

본 논문에서는 화자검증 시스템의 성능향상을 위해서 주성분 분석 (PCA) 기반 Mel-Frequency Discrete Wavelet Coefficients (MFDWC) 추출방법을 제안한다. 제안된 방법에서는 멜척도 (Mel-scale)를 근사화한 각 레벨 (level)의 각 노드 (node) 에너지를 계산하기 위해 기존의 평균치 대신 주성분 분석을 이용한 첫 번째 eigenvector를 이용한다. 이 eigenvecto.의 제곱의 합은 1로서 일반적인 가중 함수 (weighting function)의 조건을 만족하고, 또한 각 화자마다 서로 다른 값을 갖게 되므로, 화자의 특징을 더 잘 나타내는 MFDWC를 추출할 수 있다. 화자검증은 Gaussian Mixture Model (GMM) 기반의 백그라운드 모델과 화자 모델과의 점수를 비교하는 이진 결정 (binary decision) 방법을 이용하여 Universal 백그라운드 모델 (UBM)과 각 화자 모델의 값을 프레임단위로 비교하여 대상 화자의 수락/거부 여부를 결정하는 방법을 채택하였다. 특징 파라미터에 따른 화자 검증 성능변화를 확인하기 위하여 제안된 화자종속 가중함수를 이용한 MFDWC를 특징 파라미터로 이용한 경우와 Mel-Frequency Cepstral Coefficients (MFCC), Linear Predictive Cepstral Coefficients (LPCC), 기존의 MFDWC를 특징 파라미터로 이용한 경우에 대하여 성능비교실험을 수행한 결과 각각 $0.80\%,\;5.14\%,\; 6.69\%$의 향상된 성능을 나타내어 제안한 방법의 유효성을 확인할 수 있었다.

Objectives: The purpose of this study is to review the acupuncture treatment for Polycystic ovary syndrome (PCOS) in women. Methods: We searched articles in 3 search engines with keywords related to 'Polycystic ovary syndrome', 'PCOS', and 'Stein-leventhal' in February 2024. Clinical researches and case reports that used acupuncture on PCOS were included. Animal studies and non clinical data were excluded. Data on acupuncture treatment such as methods, site, duration, frequency, and period were analyzed. Results: Of 60 selected articles, there were 51 randomized controlled trials, 5 clinical trials and 4 case reports. Studies were conducted using manual acupuncture, electro acupuncture, auricular acupuncture, thread embedding acupuncture, warm needling and laser acupuncture. Most studies used more than one acupoint, and there were 78 acupoints selected for acupuncture treatment for PCOS. The most commonly used acupoint was 三陰交 (SP6)(n=50). By analyzing the network of acupoints, 關元 (CV4), 氣海 (CV6), 中脘 (CV12), 三陰交 (SP6), 血海 (SP10), 天樞 (ST25), 足三里 (ST36) were located in center of the network. The mean treatment time, number of treatments, and duration were 28.63±4.48 minutes, 34.52±29.26 times, and 98.18±38.25 days. Conclusions: The results of this study could be useful in establishing the evidence for performing standardized acupuncture treatment for Polycystic ovary syndrome.

토양수분함량과 큰검정풍뎅이의 밀도 변화와의 관계를 파악하는데 필요한 기초 자료를 얻기 위해 토양수분함량이 큰 검정풍뎅이의 난과 유충의 생존에 미치는 영향을 조사하였다. 사양토와 식양토의 수분함량 15%와 25%에서는 난과 1, 2, 3령 유충 모두 79% 이상의 생존율을 보였으나 5%와 35%에서는 현저히 떨어졌다. 이 극한 수분함량에서는 토성에 따라 난과 유충의 생존율에 차이가 있는 것으로 보였다. 큰검정풍뎅이의 난은 생존할 수 있는 낮은 수분함량의 한계에 가까워질수록 발육기간이 길어졌다. 식양토에서 33-36%의 높은 수분함량에 난을 일정 기간 처리했을 때 배자 발육을 진행된 난일수록 잘 견뎠고 처리기간이 길어짐에 따라서 전란기간이 길어졌다. 또한 높은 토양수분함량에서는 3령 유충의 섭식 활동이 뚜렷이 억제되었다.

목적: 만성 B형 간염으로 치료가 필요하였던 소아청소년 중 lamivudine을 투여하면서 전향적으로 관찰한 자료를 검토하여 약제에 대한 치료 효과를 파악하고자 하였다. 방법: 2003년 6월 1일부터 2015년 10월 30일까지 가톨릭대학교 성빈센트병원 소아청소년과를 방문하여 만성 B형 간염의 첫 치료로 lamivudine (3 mg/kg, 최대 100 mg)을 3개월 이상 투여한 55명을 대상으로 하였다. 약제 투여 후 1개월, 3개월째, 이후는 매 3개월마다 B형 간염 바이러스(hepatitis B virus [HBV]) 표지자, HBV-DNA, 간기능을 추적하였다. 치료 중단은 alanine aminotransferase (ALT) 정상, HBeAg 음성 및 anti-HBe 양성 결과가 처음 발견된 시기로부터 12개월 후로 정하였다. 결과: 연구군은 남자가 31명(56.4%), 여자가 24명(43.6%)이었고, 약제의 첫 투여 연령은 평균 8.1세, 투여기간은 평균 23.4개월이었다. ALT 정상화는 98.2% (54/55), HBeAg 양성에서 anti-HBe 양성으로의 혈청 전환은 70.6% (36/51), HBsAg 소실은 10.9% (6/55)에서 이루어졌는데 모두 7세 미만 연령이었다. 약제 투여 6개월 시 HBV-DNA <2,000 IU/mL 바이러스 반응은 78.7% (37/47)이었고, 약제 중단 12개월 후에도 바이러스 반응이 유지되는 경우는 87.2% (34/39)이었다. Lamivudine 약제 내성이 발현된 경우는 16.4% (9/55)이었다. 결론: 만성 B형 간염을 가진 국내 소아청소년에 대한 lamivudine의 치료 효과는 유사한 외국 연구 결과에 비해 더 우수하였다. 새로 권고되고 있는 다른 항바이러스제 치료에 대한 국내에서의 지속적인 연구도 필요할 것으로 판단된다.

Objectives: The aim of this study was to evaluate the effectiveness and safety of electroacupuncture for non-alcoholic fatty liver disease (NAFLD). Methods: A randomized, controlled pilot trial was conducted. Twenty-two participants were randomized into one of the two groups: an acupuncture group (n=11) and wait-list group (n=11). The treatment group received 8 sessions of electroacupuncture over 8 weeks. Twenty points (CV4, CV12, both LR14, GB26, ST25, ST34, ST40, ST36, SP4, SP6, LR3) were selected for needling. The control group did not receive acupuncture treatment during study period and followup were done in the 4th and 8th weeks after randomization in both groups. The primary outcome was body fat computed tomography and the secondary outcomes included blood test (aspartate aminotransferase, alanine transferase, triglyceride, total cholesterol, high density lipoproteincholesterol, low density lipoprotein-cholesterol, blood sugar test, ${\gamma}$-guanosine triphosphate) and body composition test (body mass index, weight, body fat mass, body fat rate, waist hip ratio). Safety was assessed at every visit. Results: There was no significant differences in between the experimental group and control group. There were no adverse events. Conclusions: The results suggest that In patients with NAFLD, electroacupuncture treatment did not induce worsening of liver disease and liver function, but it was no improvement symptoms of fatty liver. Study of herb medicine treatments and other acupuncture therapy of NAFLD are required later.

The effects of Hyungbangjiwhangrang on the enhancement of learning and memory of AD model rats were studied with Morris water maze and radial arm maze. Sample group was electrolytically lesioned on nbM, and then daily treated with the medicine for two months. Control group with nbM lesion, and sham group with the sham operation were treated the vehicle for same duration. The following results were observed.1. As the learning trials of Morris water maze processed repeatedly, sham group achiened 201.64${\pm}$33.13 seconds in 1st trial, 153.14${\pm}$61.80 seconds in 2nd, 106.21${\pm}$46.81 seconds in 3rd, 76.64${\pm}$48.40 seconds in 4th, and 52.29${\pm}$38.25 seconds in 5th. The control group achieved 224.08${\pm}$29.16 in 1st trial, 191.77${\pm}$67.97 seconds in 2nd, 177.77${\pm}$65.44 seconds in 3rd, 140.92${\pm}$68.27 seconds in 4th, and 126.46${\pm}$79.15 seconds in 5th. The sample group achieved 223.36${\pm}$23.33 seconds in 1st trial, 215.86${\pm}$38.93 seconds in 2nd, 190.79${\pm}$51.57 seconds in 3rd, 155.79${\pm}$62.67 seconds in 4th, and 127.93${\pm}$62.11 seconds in 5th. Therefore, these data shows that all three groups were improved in learning capacity as trials were repeated, but the shame group showed prominent improvement in learning compared with the control group(p<0.05).2. In memory retention test of Morris water maze that counts the staying time in the target area, sham group stayed for 15.36${\pm}$5.39 seconds, the control group stayed for 5.54${\pm}$5.64 seconds, and the sample group stayed for 7.43${\pm}$6.09 seconds. The analysis of the memory retention data shows that the sham group marked more significant improvement stati- stically in memory retention compared with the control group(p<0.05).3. In the learning of radial arm maze, the number and rate of animals that arrive the learning criteria amounted 12 out of 14, 85.7% in sham group, 4 out of 13, 30.8% in the control group, and 10 out of 14, 71.4% in the sample group So, the sample group shows better learning capacity significantly compared with the control group(p<0.05). With the experimental results above, Hyungbangjiwhangtang can be supposed to have the improving effects on the learning and memory of AD rats induced by eletronical injury of nbM.
