Steroid cell tumor is a rare ovarian sex cord-stromal tumor which accounts for 0.1% of all ovarian tumors. Until now, only 4 cases have been reported in domestic literatures. Steroid cell tumor often secrets testosterone and presents virilization in adult women or precocious puberty in children. Treatment is often performed by surgical removal, adjuvant chemotherapy and radiation, but completely accepted treatment was not existed. We experienced a case of steroid cell tumor, which was manifested by typical virilization in a 43-year old patient, who was previously performed hysterectomy and unilateral oophorectomy. So, we present with a brief review of the literatures.

발전 및 산업설비에 사용되는 많은 압력용기는 저합금가강을 사용하여 제작되고 있다. 압력용기의 내면은 부식이 미치는 영향을 최소화하기 위하여 오스테나이트계 스테인리스강으로 덧살용접을 하고 있으나, 용접 층간의 계면에서 발생하고 있는 박리균열은 압력용기의 신뢰성에 중요한 변수가 되고 있다. 본 연구에서는 DSP를 사용하여 오버레이 용접부를 고속으로 검사할 수 있는 C-scan 시스템을 개발하였다. 본 시스템은 신호 처리부 (오실로스코프, 펄서.리시버, 디지타이저, DSP), 스케너, 프로그램 및 위치 제어부로 구성되어 있다. 개발된 시스템을 사용하여 실제 오버레이 용접부에 대한 초음파검사를 실시한 결과 고속으로 신뢰성 높은 검사결과를 얻을 수 있었다. Many pressure vessels for power and industrial plant are fabricated from low alloy carbon steels. The inner sides of pressure vessels are commonly weld-cladded with austenitic stainless steels to minimize problems of corrosive attack. Disbonding cracks are often detected at the transition region of welding interlayer, which is serious problem to reliability of pressure vessels. We have developed C-scan system to high speed inspection of overlay weld using DSP(digital signal processor). This system consists of signal processing parts (oscilloscope, pulser/receiver, digitizer, DSP), scanner, program and position controller. The developed system has been applied to a practical ultrasonic testing in overlay Weld, and demonstrated high speed with precision

Background : Various types of protective footwear have been used to minimize bacterial contamination in operating rooms. In recent years, debate has arisen concerning the need for use of such protective footwear. This study was designed to provide useful data about choosing shoes most suitable for the surgical environment. Methods : Between November, 1999 and January, 2000, we performed this experimental study by comparing effect of three types of shoes (i.e., disposable shoescover, operating room-restricted shoes, and ordinary shoes) on bacterial contamination of operating rooms equipped with two different ventilation systems (i.e., high air-change, low air-change) respectively. Data were collected during two-hour sham operations in which subjects and their activities were strictly standardized. Bacterial flora were sampled from the study area floor and air colony-counts were measured. Results : In experiments involving high air-change ventilation system, there was a significant difference of floor contamination between three types of shoes, but no difference of air contamination. Under low air-change system, there was a significant difference of both floor and air contamination between three types of shoes. Conclusion : The results show that protective footwear would be unnecessary in the operating room with high air-change ventilation system, but it is important to choose suitable shoes carefully under low air-change system. Therefore, the use of outdoor shoes can be considered under high air-change system, but it would seem sensible to apply their first use in less bloody operations at the day surgery center or out-patient department to prevent transfer of body fluid into the outside environment.

연구배경: 갑상선기능항진증에 의한 갑상선중독증 환자들은 호흡곤란을 호소하며, 그 원인으로 호흡근의 근력 약화, 좌심실부전으로 인한 폐모세혈관의 울혈, 기도저항의 증가, 갑상선종으로 인한 기관의 압박, 호흡기능 이상 등이 거론되고 있다. 폐동맥고혈압이 동반된 그레이브스병 환자가 여러 증례가 보고되었으며, 폐동맥고혈압 환자에게서 갑상선 자가항체와 갑상선기능저하증의 빈도가 높음이 알려지면서 갑상선중독증이 동반된 그레이브스병 환자에게서 관찰되는 호흡곤란의 한 원인으로 폐동맥압 증가가 작용할 가능성이 제시되고 있다. 이에 저자 등은 그레이브스병 환자를 대상으로 폐동맥압을 측정하고 치료 전후의 폐동맥압의 변화를 전향적으로 연구하였다. 방법: 갑상선중독증이 동반된 그레이브스병 환자와 정상 갑상선기능을 나타낸 대조군을 대상으로 갑상선기능검사 및 갑상선 자가항체를 측정하고, 심초음파를 이용하여 치료 전후로 폐동맥압을 측정하여 폐동맥압과 갑상선기능 및 갑상선 자가항체와의 관계, 폐동맥압의 변화 등을 관찰하였다. 결과: 1. 연구대상은 대조군 10명 (남녀비 1:9, 관해 상태의 그레이브스병 3명, 갑상선종 3명, 정상인 4명), 그레이브스병 환자 26명 (남녀비 7:19)이었다. 2. 대조군과 치료 전 그레이브스병 환자의 폐동맥압은 각각 23.5±2.32 mmHg, 29.6±10.3 mmHg이었고, 치료 전의 폐동맥압과 혈청 갑상선자극호르몬 결합억제 면역글로불린 (TBII) 농도는 유의한 양의 상관관계를 보였다. 3. 26명의 그레이브스병 환자 중에서 10명 (38.5%)이 폐동맥고혈압 (기준: 폐동맥압 > 30 mmHg)으로 진단되었다. 4. 치료 전후로 폐동맥압을 측정한 13명은 폐동맥압이 치료 전 29.6±10.3 mmHg에서 치료 후 폐동맥압 22.2±6.48 mmHg로 의미있게 감소하였다. 결론: 갑상선중독증을 보이는 그레이브스병 환자의 약 40% 정도에서 폐동맥고혈압이 발견되어 폐동맥고 혈압은 그레이브스병에 흔하게 동반하는 질환으로 생각된다. 향후 그레이브스병 환자에서 관찰되는 폐동맥압의 증가와 관련한 병인, 발생기전 및 임상적 의의 등에 대한 연구가 필요할 것으로 생각된다. Background: Exertional symptoms, dyspnea and impaired effort tolerance are common in patients with Graves' disease. Proposed explanations include: high-output left heart failure, ineffective oxygen utilization and respiratory muscle weakness. In addition, pulmonary hypertension has also been reported in patients with Graves' disease. A high prevalence of hypothyroidism and positive thyroid autoantibody were also observed in patients with pulmonary arterial hypertension. Therefore, the pulmonary artery pressure in patients with Graves' disease was evaluated. Methods: Two-dimensional and Doppler echocardiographic examinations (Hewlett Packard Sonos 2500) were performed to determine the pulmonary artery (PA) pressure in 26 Graves' disease patients, both before and after treatment (23 patients with propylthiouracil and 3 with RAI), and in 10 euthyroid controls. The changes in the PA pressure after treatment were evaluated in 13 patients with Graves' disease, who became euthyroid after treatment. Results: The pulmonary artery pressure was increased in the untreated Graves' disease patients compared to the normal controls (23.5±2.32 vs. 29.6±10.3 mmHg). 38.5% of the Graves' disease patients (10/26) showed pulmonary arterial hypertension (PA>30 mmHg) and the serum TBII level was higher in the Graves' disease patients with pulmonary arterial hypertension than in those with normal PA pressure (P<0.05). In the Graves' patients who became euthyroid after treatment, the PA pressure was significantly decreased. Conclusion: 38.5% of the untreated Graves' disease patients showed pulmonary arterial hypertension, and the pulmonary artery pressure was significantly decreased in those who became euthyroid after treatment. The pathogenesis and clinical importance of pulmonary arterial hypertension in Graves' disease requires further studies (J Kor Soc Endocrinol 18:465∼472, 2003).

One of the central problem in the study of the coastal surface wave environment is predicting the transformation of waves as they propagate towards the shore. The transformation is mainly due to existence of obstacles such as breakwaters and vertical cylinders. In general, the types of wave transformation can be classified as follows; wave diffraction, reflection, transmission, scattering, radiation et al. This research deals with the wave transmission and dissipation problems for two dimensional regular waves and scrap-tire vertical breakwater. Using the unsteady mild slope equation, a numerical model has been developed to calculate the reflection and transmission of regular waves from a multiple-row scrap-tire breakwater and vertical cylinders. In addition hydraulic model experiments have been conducted with different values of properties between the piles and opening ratio (distances) between the rows of the breakwater. It is found that the transmission coefficients decrease with decreasing the opening ratio and increasing the rows of vertical cylinders. Comparison between hydralic and numerical experiments results shows resonable agreement.

Objectives : One of the objectives of this study is to estimate the prevalence rates of psychiatric diagnoses in the combined populations of psychiatric hospitals, psychiatric nursing facilities and homeless asylums using the Korean version of the Composite International Diagnostic Interview (K-CIDI), which is a comprehensive and fully standardized interview schedule to assess psychiatric disorders for diagnosis. The Other objective is to compare with previously studied prevalence rates of Psy-chiatric diagnoses using the results of this study. Methods : The study subjects, aged from 181o 64 years, were randomly selected from 64,582 institutionalized population of psychiatric hospitals, Psychiatric nursing facilities and homeless asylums as of 30, June, 2001. Twelve trained interviewers administered the K-CIDI to the selected respondents. A total of 1,875 respondents (male 1,194, female 681) completed the interview. Results : The lifetime and one year prevalences of any diagnosis excluding nicotine dependence · withdrawal, anxiety disorder, eating disorder, somatoform disorder were 88.2% (male 88.1%, female 88.3%), and 65.8% (male 62.7%, female 73.7%), respectively. The lifetime and one year prevalences of schizophrenia and other psychotic disorders were 78.5% (male 75.3%, female 83.7%), and 56.8% (male 51.9%, female 64.8%), respectively. The lifetime and one year prevalences of alcohol use disorder (dependence/abuse) were 26.7% (male 37.9%, female 8.3%), and 8.7% (male 12.8%, female 2.1%), respectively. The lifetime and one year prevalences of mood disorder were 18.1% (male 13.5%, female 25.8%), and 10.4% (male 7.2%,female 16.9%), respectively. The lifetime and one year prevalences of schizophrenia and other psychotic disorders were comparable with the 2001 community survey by 1.19% to 1.32%, and 0.51% to 0.61%, respectively. The lifetime and one year prevalences of schizophrenia were also comparable by 0.16% to 0.28%, and 0.16% to 0.25%, respectively. There were no significant changes of prevalence rates when correction were applied to other psychiatric diagnosis. Conclusion : The results of this study could be used for evaluating the distribution of psychiatric diagnoses in mental health related facilities and for planning mental health policies.
