An integrated silicon pressure sensor has been designed, fabricated and tested. The signal conditioning circuits were designed to include calibration and temperature compensation of output voltage through trimming of diffusion and ion-implanted resistors. Before trimming of resistors, the compensation parameters such as pressure sensitivity, temperature coefficient of pressure sensitivity, temperature coefficient of piezoresistors and pressure sensitivity of piezoresistors were measured. Then offset voltage, span, and temperature coefficients of offset voltage and span were calibrated by trimming of resistors. The measured output voltage met our design specification and simulation value above room temperature. But, the measured output voltage at -30°C deviated from our design specification and simulation value because the offset voltages were found to vary randomly as a function of temperature.

목적 : 2002년 말 중국에서 SARS가 발생한 이후 국내에서도 2003년 10월까지 총 3명의 추정환자, 17명의 의심환자가 보고되었다. 향후 추가적인 SARS의 유행이 우려되는 상황에서, 그간의 SARS 환자 진료에 있어서의 실질적인 준비사항, 진료 현황 등에 대한 조사를 통해 문제점을 파악하여, 향후 더 나은 대비가 될 수 있도록 개선점을 제시하고자 하였다. 재료 및 방법 : SARS로 의심되는 환자를 진료 경험이 있는 병원의료진을 대상으로 2003년 10월에 설문조사를 실시하였다. 설문에는 SARS 환자 진료 시의 실질적인 조치, 진료 현황, 병실, 응급실 및 외래에서의 격리 시설과 준비사항, 보건당국의 관리와 지원에 관한 사항을 포함하였다. 결과 : 대상이 되는 22개 병원 중 17개(17/22, 77.2%) 병원이 설문에 응하였다. SARS 환자를 위한 격리실은 응급실, 외래, 일반병실 및 중환자실에서 각각 9개(9/17, 52.9%), 5개(5/17, 29.4%), 15개(15/16, 93.7%), 4개(4/16, 25%) 병원에서 음압처리가 되어있지 않은 일인실 혹은 다인실이 사용되었고, 1개(1/16, 6.3%) 병원에서만 일반병실에서 음압격리실이 운영되었다. 입원환자의 진찰 시 개인보호구의 착용은 거의 모든 의료기관에서 이루어졌다. 보건당국에서 SARS지정병원의 시설 등을 사전에 확인한 곳은 1곳(1/12, 8.3%)이였고, 14개 병원(14/15, 93.3%)에서는 보건당국에 의뢰한 검사결과를 통하 받지 못하였다. 결론 : 의료기관에서 SARS 환자용 격리실뿐만 아니라 기존의 격리실 설비 등이 미흡하였으며, 특히 중환자실 및 외래의 준비가 더욱 부족하였다. 보건당국의 의료기관에 대한 종합적인 지원이 부족하였고, 병원과의 원활한 연계가 잘 이루어지지 않았다. SARS 만이 아닌 격리를 필요로 하는 질환의 적절한 진료를 위해 향후 병원 시설의 정비와 정부차원에서의 보다 구체적이고 실질적인 대책마련이 필요하다. Background : There was an worldwide outbreak of the Severe Acute Respiratory Syndrome (SARS) originated from China in late 2002. During that period three cases of suspected SARS and 17 cases of probable SARS were reported in Korea. With the concerns about the reemergence of SARS-coV transmission, it is important to be prepared for any possibility. So, this study is aimed to analysis the past measures in managing SARS and propose the amendatory plans to improve the preparedness. Materials & Methods : Questionnaires were collected among clinicians with any experience in managing the probable or suspected SARS cases in Oct. 2003. 17 out of 22 hospitals responded to the questionnaire. The contents in the questionnaire were practical activities, personal equipments, response plans, isolation facilities in emergency centers, outpatient clinics, general wards and intensive care units, and relationship with the public health department. Results : The dedicated isolation rooms in emergency centers, outpatient clinics, general wards, and intensive care units were prepared in 9 (9/17, 52.9%), 5 (5/17, 29.4%), 15 (15/16, 93.7%), and 4 (4/16, 25.0%) hospitals, respectively. Except for one hospital that newly made negative pressure room for SARS, single or multi-bed rooms without airborne infection control were used in all the other hospitals. The personal precaution principles were kept quite well in general wards. Before the designation of SARS hospital by the public health department prior evalution to see if the hospital was suitable for managing SARS was conducted in only 1 (1/12, 8.3%) hospital. The results of laboratory diagnosis were reported back in 1 (1/15, 6.6%) hospital. Conclusions : The isolation facilities which can control airborne infection were almost deficient not only for SARS but also for other respiratory transmissible diseases. For the infection control of transmissible diseases including SARS, more investment is needed on medical facilities and comprehensive support from the public health department required.

Autosomal dominant polycystic kidney disease(ADPKD) is one of most common hereditary disorder. It is potentially fatal and the major mobilities are hypertension and renal failure. To elucidate clinical characteristics and outcomes of ADPKD, 67 ADPKD patients were analyzed retrospectively. The male to female ratio was 48 years for males and 42 years for females. The factors leading to the dignosis of ADPKD were flank or abdominal pain (46%), palpable abdominal mass (24%), incidental findings (18%), gross hematuria and headache. Urinalysis result showed hematuria (31%), proteinuria (19%), pyuria (18%). Among renal complications hypertension (67%) was the most common. Other complications were urolithiasis (16%) upper urinary tract infection (9%), cyst infection (7%). Azotemia was observed in 24% of cases. Echocardiography showed left ventricular hypertrophy in 24% and valvular regurgitation in 18% of cases, but there was no mital valve prolapse. Cerebrovascular events occurred in 6 cases (2 cases of intervertebral hemorrhage and 4 cases of cerebral infarction). Hipatic cyst were observed in 64% of cases. Eighteen cases culminated in end stage renal failure (ESRF) at an of 47. According to this study, the most common complications of ADPKD was hypertension (67%), ESRF (27%), and cerebrovascular event (9%). Hypertension was more frequently observed in increased creatinine group than normal.

Korean hemorrhagic fever(KHF) reported for the first time in Korea in 1951, althought it had previously been known from both Manchuria and Russia. Since that time it has been known as Korean hemorrhagic fever and has remained endemic near the Demilitarized Zone between North and South Korea. In 1976 and 1978, Lee et al reported the isolation of Hantaan virus, the etiologic agent of KHF, from the patients and Apodemus agrarius coreae collected in the endemic areas of KHF and developed Lee's method of serological diagnosis of KHF. Very recently, Lee et al demonstrated virus excretion in the urine of infected Apodemus agrarius for a long time. The urine from both Apodemus agrarius and susceptible human were examined its effect on the infectivity of Hantaan virus to Apodemus mice. The results are summarized as follows: 1) The urine from Apodemus agrarius rodent, the natural reservoir of Hantaan virus, had higher activity to inactivate the infectivity of Hantaan virus than that of human. 2) The urine from Apodemus agrarius just after sampling was pH 8.3 and it had stronger antiviral activity than the urine adjusted to pH 7.2. 3) pH of human urine just after sampling was 6.1 and this urine decreased 10~100 10? of the virus after 3 hours in room temperature, but the urine with pH 7.2 had no change to infectivity of the virus.

Carcinoid tumors have been reported in a wide range of organs but most commonly involve the lungs, bronchi and gastrointestinal tract. Within the gastrointestinal tract, appendix is the most common location for carcinoid, followed by the distal small intestine, the rectum, and the stomach. Among these, primary involvement of the ampulla of Vater is extremely rare. We report a case of carcinoid tumor of ampulla of Vater. A 62-year-old man presented with epigastric soreness. Gastroduodenal endoscopy showed hyperemic bulging mass on ampulla of Vater and diagnosed as carcinoid tumor by histologic finding, with immunohistochemical study. In ^(111)In-octreoscan, tumor had regional lymph node metastasis, but no evidence of distant metastasis. Pancreatoduodenectomy with lymph node dissection was performed.
