Background Polyurethane coating of breast implants has been shown to reduce capsular contracture in short-term follow-up studies. This 30-year study is the longest examination of the use of polyurethane-coated implants and their correlation with capsular contracture. Methods This study evaluates the senior surgeon's (F.D.P.) experience with the use of polyurethane-coated implants in aesthetic breast augmentation in 382 patients over 30 years. Follow-up evaluations were conducted for six months after surgery. After the six-month follow-up period, 76 patients returned for reoperation. The gross findings, histology, and associated capsular contracture were noted at the time of explantation. Results No patient during the six-month follow-up period demonstrated capsular contracture. For those who underwent reoperation for capsular contracture, Baker II/III contractures were noted nine to 10 years after surgery and Baker IV contractures were noted 12 to 21 years after surgery. None of the explanted implants had macroscopic evidence of polyurethane, which was only found during the first five years after surgery. The microscopic presence of polyurethane was noted in all capsules up to 30 years after the original operation. Conclusions An inverse correlation was found between the amount of polyurethane coating on the implant and the occurrence of capsular contracture. Increasingly severe capsular contracture was associated with a decreased amount of polyurethane coating on the surface of the implants. No contracture occurred in patients whose implants showed incomplete biodegradation of polyurethane, as indicated by the visible presence of polyurethane coating. We recommend research to find a non-toxic, non-biodegradable synthetic material as an alternative to polyurethane.

본 연구의 목적은 한국인중 성장기에 있는 연령층에서 좌,우안 크기와 동공중심간거리가 연령변화에 따라 어떻게 변화되고 있는가를 비교하는데 있다. 대상은 7세부터 30까지의 연령층으로 전국의 남,녀를 무작위로 선정하여 5그룹으로 나누어 조사대상으로 하였다. 오른쪽눈 외안각에서 왼쪽눈 외안각까지의 길이와 두눈사이 길이가 최고치를 나타낸 것은 모두 B그룹에서 각각 94.30mm, 36.66mm이었고 각 연령별로 좌,우 눈의 크기 차이가 없는 사람의 비율은 ABC 그룹이 10.0% 정도로 나타났고 E 그룹에서는 22.7%의 수치를 나타내었다. 전체 길이에서 두눈 크기의 평균값을 뺀 수치는 동공중심간 거리보다 더 넓었다. B 그룹이 5.72mm, E 그룹에서는 1.13mm의 차이를 나타내 중등학생 해당자가 만 25세 이상 해당자보다 4.00mm이상 더 큰 수치를 나타냈다. 따라서 동공 중심은 눈의 중심에서 약간 코쪽으로 치우쳐 있음을 알 수 있고 어련 연령층 해당자가 만 25세 이상 해당자보다 더 많이 치우쳐 있음을 예상할 수 있다.

The purpose of this study was to investigate the effect of sex and menopausal age on the thickness and density of squamous portion of the temporal bone as the membranous bone. Patients who visited a general hospital in Chungnam and had a computed tomography (CT) examination of the head. A retrospective study was conducted with 120 subjects (30 men under 55 years old, 30 men over 56 years old, 30 women under 55 years old, and 30 women over 56 years old). Axial images of the squamous portion in the temporal bone were obtained from CT of the head. For this image, a slice sensitive profile (SSP) was acquired with an image analysis program and these were evaluated. The thickness was measured by using a digital ruler to measure the full width at half maximum (FWHM) of the SSP, and the density was measured in hounsfield unit (HU). These by gender were measured to be about 0.5 mm thinner in the temporal bone in men than in women, and there was a significant difference. The density was measured to be about 200 HU higher in women than in men of it, and there was a significant difference. As a result, it in women was thicker and had a lower density. The thickness of it in men and women over 56 years of age was 0.8 mm or more thicker in women and less than 400 HU in density. As a result, the women group over the age of 56 showed a distinct increase in thickness and decrease in density, different from other target groups. It is expected that the results of this study could be used as basic data for a new bone density measurement site study.

This survey was carried out to clarify the consumers' behavior related the purchase and use of women's dress shoes. The subjects participated in this study were 386 Korean women. Their age were ranged from 18 to 86 years. The results of this study were as following; 1. The most popular women's dress shoe sizes were 235 and 240. 2. 82.6% of subjects had experienced uncomfortable fit when they wore dress shoes. 3. The subjects aged over 30 years preferred low heel shoes. They valued wearing comfort above fashion trend in shoe design consideration. 4. The subjects aged under 30 years gave more emphasis on fashion trend than comfort and fit when they purchase dress shoes. 5. Consumer's experience of unfit with dress shoes was different with age. The younger subjects complained improper bottom sole shape. The older subjects had experience of unfit with outshell design and material. The subjects aged over 60 years thought that their dress shoe design was too narrow at the toe and lack for flexiblity of shoe material.

Three hundred and sixty seven cases of open heart surgery were done in the Department of Thoracic and Cardiovascular Surgery, Pusan National University Hospital from July, 1981 to October, 1985. 1. The age distribution of congenital heart disease patients was 3 to 41 years old and mean age was 12.7 years and of acquired heart disease was 9 to 57 years old and mean age was 30.9 years. 2. There were 281 cases [64.9%] of acyanotic congenital heart anomalies, 43 cases [11.7%] of cyanotic anomalies and 86 cases [23.4%] of acquired heart disease. 3. For myocardial protection, Bretschneider and potassium glucose solution had been used as cardioplegic solution but recently GIK solution is being used as secondary cardioplegic method by infusing repeatedly every 30 to 40 minutes time interval with excellent results. 4. The overall mortality was 8.2%. And the mortality rate in each disease entity is 2.5% in congenital acyanotic cases, 32.6% in congenital cyanotic cases and 11.6% in acquired valvular disease.

목적: 이 연구의 목적은 새롭게 개발된 대한치과보철학회의 보철물 평가 기준을 적용하여 고정성, 가철성 그리고 임플란트 보철물의 성공과 실패를 평가함으로써 보철물의 수명과 이에 관련된 요인을 분석하는 데 있다. 대상 및 방법: 전국 13개 대학/종합병원 보철과에 내원한 환자들을 대상으로 구강내 사용중인 보철물을 평가하였다. 대한치과보철학회의 기준에 따라, 수는 성공, 우, 양, 가는 실패로 규정하고, 실패한 보철물의 평균 사용기간과 실패와 관련된 요인을 분석하였다. Kaplan-Meier 분석에 의한 성공률을 분석하였다. 결과: 고정성 보철 810 증례, 가철성 보철 519 증례, 그리고 임플란트 보철 475 증례, 총 1,804 증례가 연구에 포함되었다. 검사 시점에 실패로 판정된 보철물의 평균 사용기간은 고정성 보철물은 $11.41{\pm}0.30$년, 중간값은 10년이었고, 가철성 보철물은 $8.18{\pm}0.29$년, 중간값 7년이었으며, 임플란트 보철물은 $7.99{\pm}0.30$년, 중간값은 7년이었다. 실패와 관련있는 요인 중 고정성보철물은 유닛 수, 지대치 수, 근관치료된 지대치 수, 치태지수였고, 가철성 보철물의 경우 대합치였으며 임플란트 보철의 경우 임플란트 개수, 사용기간, 치태지수였다. 결론: 대한치과보철학회의 기준으로 보철물을 평가한 결과, 실패한 보철물의 평균수명은 고정성 11.41년, 가철성 8.18년, 그리고 임플란트 보철물은 7.99년이었다.
