Objective: This study was designed to estimate the frequency and risk factor for edenomyosis Methods: The clinical records of 623 women undergoing hysterectomy were retrieved in the Department of Obstetrics and Gynecology, Soonchunhyang University Hospital, during 5 years, from Jan. 1995 to Dec. 1999. Results: The following result were obtained. 1. Adenomyosis was found in 247 of 623 patients(39.6%) 2. The highest incidence was 40-49 years of age group, an incidence of 46.6% and mean age was 44.7 years. 3. Adenomyosis was more frequently observed in parous women than non-parous women, such as 93.1% and 6.9%, respectively. 4. Dysmenorrhea, metrorrhagia, pelvic pain and vaginal bleeding were common symptom of adenomyosis, an incidence of 28.7%, 19.0%, 18.2% and 16.2%, respectively. 5. Myoma was the most combined disease in adenomyosis, showing the incidence of 54.7%. 6. Grossly, the size of uterus was enlarged more than 10 weeks gestational size in adenomyosis, an incidence of 61.9%. 7. Preoperative diagnostic accuracy of adenomyosis was 6.9%. Conclusion: The results show that deeply understanding of the common symptoms and epidemiology of adenomyosis improve the preoperative diagnostic accuracy.

연구목적 : 전산화 Standard Progressive Matrices(SPM) 검사의 한국인 성인 표준자료를 확립함으로써, 간이로 지능을 평가하는 경우에도 보다 정확하게 지능지수를 추정하기 위해서 본 연구를 수행하였다. 방 법 : 18세 이상의 남녀 정상인 자원자 353명을 대상으로 전산화 SPM 검사를 시행하고, 백분율 및 표준점수(T-점수)를 기준으로 하여 표준화 자료를 작성하였다. 전체 대상군을 성별, 연령별로 구분한 후 평균과·분포가 유사한 집단은 군을 합치는 방법을 사용하였다. 한국인 표준자료에 근거하여 추정한 SPM 지능지수와 외국인 표준자료에 근거하여 추정한 SPM 지능지수를 각각 KWAIS 지능지수와 비교함으로써 타당도를 검증하였다. 결 과 : 18∼30세, 31∼40세, 41∼50세, 51세 이상의 연령군으로 구분된 한국 정상 성인의 SPM 표준화 자료를 산출하였다. 본 연구 결과에 의한 표준화 자료를 적용하여 지능지수를 추정하는 것이 현재 사용하고 있는 외국인의 표준화 자료를 이용하는 것보다 KWAIS 지능지수에 더욱 근접한 결과를 보였다. 결 론 : 18세에서 50세까지의 한국인 남녀에게는 간이지능평가도구로서 전산화 SPM 검사의 한국인 표준화 자료를 유용하고 타당하게 적용할 수 있음을 확인하였다. Objectives : We conducted this study to provide standardized data of the computerized Standard Progressive Matrices(SPM) test in Korean adults. Methods : The computerized SPM test was administered to 353 healthy volunteers aged 18 years over. We provided the standardized data(percentile and standardized T-scores) for the groups with similar mean and distribution of SPM scores, which was originally divided by age and sex. The validity of the new standardized data was tested by comparing IQs estimated by SPM and K-WAIS. Results : The standardized SPM data were provided for four age groups : 18 to 30 years, 31 to 40 years, 41 to 50 years, 51 years and over. IQ estimated by this standardized data tends to be closer to IQ by K-WAIS than the IQ estimated by foreign normative data. Conclusion : The standardized data of the computerized SPM were proven to be a useful and valid tool for measuring IQ briefly, compared with the conventional way of measuring IQ.

Purpose: T-tube is a major procedure that prevents complication by biliary decompression, but which is accompanied by complications. Therefore, several procedures such as ENBD, PTBD, and antegrade biliary stent have been attempted, but with controversies as to which procedure is superior. Also, there are no standard procedures after laparoscopic CBD exploration. We performed this study to ascertain the most appropriate biliary drainage procedure after laparoscopic CBD exploration. Methods: From March 2001 to December 2009, 121 patients who underwent Laparoscopic CBD exploration in Gunyang University were included for retrospective analysis. The patients were divided to 4 groups according to type of procedure, and we compared clinical parameters including age and gender, operation time, hospital stay, start of post-operative diet, and complications. Results: There was no difference in age, gender, mean operation time, postoperative diet between the 4 groups. Hospital stay in the Stent group was shorter than T-tube group. There were 10 (7%) complications that occurred. Two 2 occurred in the T-tube, 3 in PTBD, and 5 in the Antegrade stent group. There were more complications in Stent group but no significant statistical difference. In 5 cases with remnant CBD stone, a total of 4 (3 PTBD, 1 Stent) was performed by endoscopic CBD stone removal. One T-tube case was removed easily by choledochoscopy through the T-tube. Three migrated and the impacted stents were removed by additional endoscopy. Perioperative biliary leakage (1) and peritonitis (1) post t-tube removal were resolved by conservative treatment Conclusion: T-tube appears to be an appropriate method to patients who are suspected to have remnant CBD stones. Multiple procedures may be performed on a case by case basis such as performing PTBD first in a suspected cholangitis patient.

Endoscopy and Imaging Modalities/Basic Science of Gastrointestinal Disorders/Miscellaneous : Risk Scoring System For Colorectal Cancer In Men Developed By Harvard Group May Not Be Applicable To Korean

Background/Aims: Colorectal cancer (CRC) is one of the leading causes of cancer death in Korea. Since CRC is preventable by colonoscopy with polypectomy, risk assessment tool is necessary for appropriate screening recommendation. Recently, some researchers of Harvard Medical School suggested a simple equation to obtain risk score for CRC. The score can be calculated as follows: risk score=(2: age 50-59 years)+(4: age 60-69 years)+(6: age≥70 years)+(1: BMI≥25-30 kg/m2)+(2: BMI≥30 kg/m2)+(1: history of past or current smoking)+(1: alcohol use>weekly). We tested the applicability of this scoring system in Korean population to verify the propriety of future prospective study. Methods: We retrospectively analyzed the results of colonoscopy done for health screening in men between April 2003 and August 2007 in Daegu Catholic Medical Center. Among 1845 cases, colorectal polyp was found in 665 cases. Risk scores were obtained using the equation in 654 eases with polyp. We evaluated the relationship between the incidence of high risk polyp (HRP) or CRC and the risk score. HRP was defined as more than 10 mm in size or severe dysplasia or villous component of pathology or multiple polyps. Results: Among 654 cases, HRP or CRC was found in 193 cases. The incidence of HRP or CRC had positive association with the risk score (P<0.05). The incidence of HRP or CRC also had positive association with the patient age (P<0.05) and age was a major influencing factor for the incidence. Within the same age group, there was no definite association between the incidence of HRP or CRC and the risk score (P<0.05). None of smoking history, alcohol use, or body mass index was an meaningful predictor of HRP or CRC in the same age group. Conclusions: The patients with higher risk score showed higher incidence of HRP or CRC. But age was the only significant factor having discriminative ability. We could not validate the risk scoring system suggested by Harvard group in this study. That might be partly explained by ethnic difference. Because We included not only CRC but also HRP in the analysis, that might be another reason. We hoped this easy risk scoring system can give us more information other than age to select men with higher risk of CRC but it was apparently disappointing. There is a need to develop our own predictive model for the incidence of colon cancer in Korea.

The Effect of the Transparency of an Overdense Plasma on Proton Beam Generation by an Intense Ultra-Short Laser Pulse

Kwon Duck-Hee,Jeong Young-Uk,Kitae Lee,Park Seong-Hee 한국물리학회 2006 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.49 No.1

The interaction of an ultra-short intense laser with an overdense plasma is numerically studied from the point of view of accelerated proton beam generation. We use a one-dimensional particle-in-cell (PIC) code for simplicity. The laser intensity is about 1018 1019 W/cm2, the pulse width is a few tens of fs, and the plasma density is about 4nc 10nc (nc !2me0/e2). Various forces to accelerate proton ions are investigated as the light intensity and the plasma density are varied . One of the main forces is light pressure, and another is the space-charge-field force induced by rapid electron dispersion. Different behaviors of the energy distribution of the accelerated proton beam are observed under different conditions for the transparency and the opacity of the laser pulse. When the laser light is mostly reflected in front of the plasma slab, the proton ion beams is more collimated by the light pressure. In addition, the kind of polarization of the laser affects the energy spectrum of the accelerated protons, and circular polarization is preferred to linear polarization for effective collimation of an accelerated proton beam.

Distribution of S-alleles among Korean Apples by PCR and Cross-pollination

Seong Heo,Soon-Il Kwon,Jeong-Hwan Hwang,Yong-Uk Shin,Mok-Jong Kim,Bong Ju Park,Sung-Il Oh,Young-Jae Oh,Daeil Kim 한국원예학회 2012 원예과학기술지 Vol.30 No.6

To acquaint correct information about the fertilizability and analyze S-allele based genetic diversity among Korean apples, we investigated self-incompatibility genotypes by PCR and cross-pollination tests in field. As a consequence, S-genotypes of Korean apples were distributed within narrow genetic diversity as S1S3 for ‘Hongro’ and ‘Saenara’; S1S9 for ‘Gamhong’ and ‘Manbok’; S3S5 for ‘Seokwang’; S3S9 for ‘Sunhong’, ‘Seohong’, ‘Chukwang’, and ‘Hwahong’. Coupled with cross-pollination experiments in field, our results provide support for the view that apples are fully compatible when both of their S-loci differ and semi-compatible when they carry one different and one identical S-locus. Furthermore, the results of this study indicate that S-alleles have to be extended to various genotypes for Korean apple breeding.

P140 : Clinical effect of bovine amniotic membrane and hydrocolloid on laser wound: comparative, open label, randomized, clinical trial

( Seong Uk Min ),( Ji Young Yoon ),( Seon Yong Park ),( Hyuck Hoon Kwon ),( Dae Hun Suh ) 대한피부과학회 2013 대한피부과학회 학술발표대회집 Vol.65 No.2

Background: Bovine amniotic membrane (BAM) accelerates epithelization, and have anti-inflammatory, anti-angiogenic and strong analgesic effects. Objectives: To evaluate the clinical effects of BAM on wound by ablative laser treatments and compare the clinical effect of BAM on wound with that of hydrocolloid dressing. Methods: Forty-nine subjects with nevi or scars requiring ablative laser treatment were enrolled. For comparing the efficacy, we divided the body into several areas such as face, neck, trunk, upper extremity and lower extremity and included the patients with two or more same skin lesions in the same area of the body. After ablative laser treatments, BAM and hydrocolloid dressing were applied to wound. Objective and subjective assessment were done at baseline, 1, 4, 6, 8, 11, 13 days after treatment. Histologic change was assessed by skin biopsy. Results: The site treated by BAM showed shorter epithelization time than hydrocolloid site (6.7 Vs 9.2 days). Epithelialization was confirmed by skin biopsy. Erythema and oozing at BAM-treated site after laser treatment faded away more quickly than those at hydrocolloid-treated site. Satisfaction score of BAM treatment was higher than that of hydrocolloid treatment. No adverse effects other than mild pruritus were observed. Immunohistochemistry revealed different growth factor profile between two treatment modalities. Conclusion: BAM could make benefits on wound by ablative laser treatment compared with hydrocolloid dressing.
