Mitral valve disease is the most common disease of the acquired heart diseases, and atrial septal defect is also one of common congenital heart diseases. Coexistence of these two lesions is rare, but of great hemodynamic interest. Among 443 cases with mitral valve disease and 90 cases with atrial septal defect experienced in the Department of Thoracic Surgery, Seoul National University Hospital, there were 6 cases with atrial septal defect complicated by mitral valve disease. 1. Of the 6 patients, four were female and two were male. The age was ranged from 18 to 46. 2. Atrial septal defect was ostium secundum type in all cases, and the mitral valvular lesions were regurgitation in four and stenosis in two. Type II ventricular septal defect was also combined in one of the cases. 3. The atrial septal defect was corrected by, primary closure and the mitral valve was replaced with the prosthetic or bioprosthetic valve in all cases. The combined ventricular septal defect was closed using Teflon felt patch. 4. The operative result was good except in one who was expired of bacterial endocarditis 4 months after hospital discharge.

A clinical analysis was performed on 383 cases of chest injurjes experienced at Department of Thoracic Surgery, Seoul National University Hospital during 21 year period from 1957 to 1977. Of 383 patients of chest injuries, 209 cases were result from nonpenetrating injuries whereas 175 were from penetrating injuries, and there were 258 cases of hemothorax or/and pneumothorax, 162 of rib fracture, 33 of foreign body, 26 of clavicle fracture, 26 of lung contusion, 17 of diaphragmatic laceration, 14 of hemopericardium, 14 of flail chest and others. Stab wound was the most common in penetrating injuries and followed by gunshot and shell fragments. The majority of nonpenetrating chest injury patients were traffic accident victims. and fails accounted for the next largest group of accidents. Chest injuries were frequently encountered in the age group between 16 and 50 years, and 321 patients were male comparing to 62 of female. In blunt chest injuries the patients with five or more rib fractures had a 85 per cent incidence-of intrathoracic injury and 19 per cent had an intraabdominal organ damage, whereas those with four or less rib fractures had a 69 per cent and a 6 per cent incidence respectively. The principal associated injuries were cerebral contusion on 19 cases, renal contusion on 10, liver laceration on 7, peripheral vessel laceration on 5, spleen laceration on 3 and extremity fracture on 18 patients. The principles of therapy for early complications of chest trauma were rapid reexpansion of the lungs by thoracentesis [46 cases] and closed thoracotomy [125 cases] but open thoracotomy .had to be done on 90 cases [23-5%] because of massive bleeding or intrapleural hematoma, foreign body, cardiac injury, diaphragmatic laceration and bronchial rupture. The over all mortality was 2.87 per cent [11 among 383 cases], 8 cases were from penetrating injuries and 3 from nonpenetrating injuries.

Primary intrathoracic neoplasms occur frequently, and the most frequent intrathoracic tumors are of pulmonary or bronchogenic origin. Second in frequency are mediastinal tumors, and least frequency or comparatively rare are the neoplasms arising from the wall of the thorax and extending into the thoracic cavity. Of all intrathoracic tumors, fibroma is extremely rare. Recently, we have experienced a huge rapid growing intrathoracic fibroma originating from thoracic wall, which is removed successfully and confirmed histopathologically. Authors present one case of fibroma and discussion with a brief review of the relevant literatures.

This paper presents a method for designing a dual-polarized monopulse antenna operating at 2.2~2.3GHz. The proposed antenna consists of five coax-fed crossed dipoles, a cylindrical cavity and a circular ground. The sum pattern is realized using a crossed dipole inside the cavity at the ground plane center and the difference pattern is realized using four crossed dipoles equally spaced around the cavity. The sum pattern of the designed antenna has a maximum gain of 9.18dBc, a gain taper of 8.62dB at 64° from the antenna boresight and the difference pattern has a null depth of -45.0dB and a gain taper of 11.44dB. A tracking sensitivity of 0.86(V/V/BW) is obtained when the proposed antenna is applied to a reflector with a diameter of 4.6m and F/D of 0.4.

To estimate fuel consumption rate of a common vehicle, a car can be tested on chassis dynamometer or simulated following the driving mode which consists of time-velocity profile and time-grade profile. But estimation of the military vehicle is more difficult than common vehicle because of driving in high grade change and manual transmission. In this study, Military vehicle model is developed in MatLab Simulink to estimate real driving fuel consumption rate with time-velocity profile, time-shift gear profile and time-grade profile. On-road car tests of forward military operation area to verify the vehicle model are carried out for analyzing the result of engine torque and rpm simulation and comparing with those of the experiments.

목 적:쯔쯔가무시(Tsutusgamushi)병은 리케치아 (Rickettia) 감염증의 하나로 인체병원체인 R. tsutusgamushi에 감염된 좀 진드기 유충(chigger)에 물렸을 때 감염이 된다. 임상적으로 물린 부위에 가피형성, 발열, 발진을 특징으로 하는 급성 발진성 열 성 질환이다. 치료약제로는 Tetracycline, Doxyctcline, Chloramphenicol 등이 사용되고 있으나 소아에서는 약의 부작용으로 인하여 약의 사용에 있어 많은 제한을 받게 되는 경우가 많다. 최근 산모에서 발생한 쯔쯔가무시병을 macrolide 계통의 항생제인 Azithromycin을 치료한 것을 발표한 바가 있다. 이에 저자들은 소아에서 비교적 사용이 용이한 또 다른 macrolide 계열의 항생제인 Clarithromycin을 사용하여 쯔쯔가무시병에 대한 효과를 알아보고자 하였다. 방 법 2001년11월에 마산파티마병원에 급성 열성 질환으로 내원한 환자 중 임상적으로, 혈청학적으로 쯔쯔가무시병으로 진단을 받은 내과 환자 7명과 소아과 환자 3명을 대상으로 Clarithromycin(Ab- bott Laboratories, NorthChicago, IL, USA) 투여하여 쯔쯔가무시병의 치료효과에 대하여 알아보았다. 쯔쯔가무시병의 임상적 진단은 하루 이상의 발열과 최근 수주 이내에 감염 가능성이 있는 지역인들이나 산 등의 지역에 노출된 병력이 있으며 림프절 종대, 반점 구진상의 피부발진과 특징적인 가피 등 의 특징적인 이학적 소견이 동반된 경우 진단을 위한 검사를 실시하였다. 혈청학적인 기준은O. tsutsugamishi 항원 감작 면양 적혈구(sheep red blood cell)를 이용한 수동응집반응검사(passive hamagglutination assay : PHA)인 GENEDIA Tsutsugamushi PHA IIkit(Green Cross, Korea)를 이용하였는데 O. tsutsugamishi 항체가가 1 : 80 이상이면 양성으로 판정하였고 추적검사는 실시하지 않았다. Clarithromycin의 투여량은 성인의 경우 500 mg을 하루에 2회 경구투여 하였으며 소아의 경우 15 mg/kg으로 하루에2회 경구투여 하였다. 결 과 1) 총 대상 환자는 성인 7명, 소아 3명이었으며 성인의 경우 남자는 3명, 여자는 4명이었고 연령은 28세부터 76세까지이었다. 소아의 경우 남자는 1명, 여자는2명이었고4세부터 7세까지의 연령의 분포를 보였다. 임상증상으로는 전 환자에서 발열과 근 육통, 두통 등이 동반되었고 이학적 검사상 발진과 가피를 발견할 수 있었다. 7례에서 PHA 항체 양성 반응 보였고8례에서 간기능의 이상을 보였고6례 에서는 혈소판 감소가 있었다. 간기능의 이상을 보인 환자8례 중 추적관찰이 가능했던 환자6명에서 간기능 정상이 되었고 혈소판 감소증을 보인 환자 중 추적관찰이 가능했던 5명에서 혈소판의 수가 정상적으로 되었다. 2) Clarithromycin 투약 후 열이 떨어지는데 걸리 는 시간은 평균 1.3일(1 ~ 2일)이었으며 투약기간은 6일에서11일까지 평균7.2일을 사용하였다. 전 환자에서 특별한 합병증 없이 회복이 되었다. 결 론 본 연구에서 쯔쯔가무시병의 환자의 치료에 있어 Clarithromycin 투여가 효과적이었으나 증례 수가 많지 않아 향후 더 많은 연구가 이루어져할 것으로 사료된다. Purpose : Scrub typhus(tsutsugamushi disease) is a febrile disease characterized by fever, rash, eschar, lymphadenopathy. Therapy with tetracycline(doxycycline) or chloramphenicol is currently recommended for the treatment for scrub typhus. But there are limitations in usage a tetracycline(doxycycline) for scrub typhus in the children. Recently, there was a report that azithromycin, a macrolide antibiotic was used for scrub typhus in pregnant woman successfully. So we evaluated the effectiveness of the Clarithromycin, other a macrolide antibiotic, for scrub typhus. Methods : Seven patients with scrub typhus at department of internal medicine and three patients with scrub typhus at department of pediatrics Masan Fatima Hospital were involved for this study. A serologic diagnosis for scrub typhus were performed by use of passive hemagglutination test. Clarithromycin(Abbott Laboratories, North Chicago, IL, USA) was administrated orally in a daily dose of 500 mg for adult patients and 15 mg/kg/bid/day for pediatric patients. Results : There were 7 cases of adult patients, varying from 28 to 76 years of age and 3 cases of pediatirc patients, varying from 4 to 7 years of age with scrub typhus. All of cases had fever, myalgia, headache, rash, eschar. Seven cases had positive passive hemagglutination test and eight cases had abnormal liver function. Mean duration for the removal of fever after medication was 1.3 day(1~2 days) and all cases were recovered without complications. Conclusion : Our results suggest that Clarithromycin therapy may be effective for scrub typhus.

목 적 : 장바이러스는 무균성 뇌막염의 가장 흔한 원인으로 알려져 있으며 1993년과 1996년에 국내에서 유행하였던 무균성 뇌막염은 주로 echovirus type 9에 의한 것이었다. 무균성 뇌막염의 유행시 원인 바이러스를 밝혀내는 일은 진단뿐 아니라 역학적인 의미에서도 필요하다. 이에 저자들은 1997년도에 마산 지역을 포함하는 경상남도 중부지역에서 유행하였던 무균성 뇌막염 환자를 대상으로 원인 바이러스를 규명하고 임상증상과의 관계를 추구하고자 본 연구를 시행하였다. 방 법 : 1997년 3월부터 10월까지 마산 파티마병원에 무균성 뇌막염으로 진단된 환자 239명(소아 213명, 성인 26명)에서 채취한 검체(뇌척수액 128례, 대변 239례)를 대상으로 바이러스 배양과 enterovirus RNA 검출을 시행하였다. 배양된 바이러스는 면역형광법을 이용하여 동정하였고 장바이러스 RNA는 reverse transcription-polymerase chain reaction(RT-PCR)을 이용하여 확인하였다. 결 과 : 1) 환자의 발생시기는 3월부터 10월까지였으며 6월에 가장 많은 환자의 분포를 보였다. 2) 대상 환자 239명(소아과 213명, 내과 26명)의 연령별 분포를 보면 소아환자의 평균연령은 4.9세로 신생아에서부터 15세에 이르기까지 다양하게 분포하였고 16세이상 내과 병동에 입원하였던 환자는 평균 연령이 24.2세로 16세에서 35세까지의 연령 분포를 보였다. 3) 환자에서 바이러스 분리는 뇌척수액 128례중 53례(41.4%), 대변에서는 239례중 163례(68.2%)에서 분리가 되었다. 4) 분리된 바이러스의 결과를 보면 뇌척수액에서는 echovirus type30이 16례(30.2%), echovirus type 6이 6례(11.3%), echovirus type 4가 1례, 아형이 결정되지 않은 echovirus가 4례, coxsackievirus type B5가 1례, 아형이 결정되지 않은 enterovirus가 24례 이었다. 한편 대변에서는 echovirus type30이 72례(44.2%), echovirus type 6이 21례(12.9%), echovirus type 4가 1례, 아형이 결정되지 않은 echovirus가 17례(10.4%), coxsackievirus type B5가 1례, A24가 2례, 아형이 결정되지 않은 coxsackievirus type B가 3례, 아형이 결정되지 않은 enterovirus가 46례였다. 결 론 : 1997년 3월부터 10월까지 경상남도 중부지방에서 무균성 뇌막염의 유행이 있었으며 원인 바이러스는 echovirus type 30이 주된 원인 바이러스이었고 그 외에 echovirus type 4, 6, coxsackievirus B5, coxsackievirus A24에 의한 무균성 뇌막염의 산발적인 발생이 있었다. Purpose : Enteroviruses are the most common cause of aseptic meningitis. The epidemics of aseptic meningitis in 1993 and 1996 were mostly caused by echovirus type 9. Identification of the causative virus of aseptic meningitis in epidemics, is very important not only for diagnosis but also for epidemiologic purpose. The purpose of this study was to identify the causative virus and investigate the relationship between aseptic meningitis, prevailed in Masan and surrounding areas in Kyoungsangnamdo in 1997, and its clinical manifestations. Methods : One hundred twenty eight cerebrospinal fluid(CSF) and 239 stool specimens were obtained from 239 patients(213 children and 26 adult patients) with aseptic meningitis were admitted to Masan Fatima Hospitals from March to October 1997. Viral isolation and serotype identification was performed by cell culture and immunofluorescent test. Enteroviruses not typed by immunofluorescent test was confirmed by reverse transcription-polymerase chain reaction(RT-PCR). Results : 1) The peak incidence was noted in June. 2) The age of 239 patients(pediatrics-213 cases, internal medicine-26 cases) that were diagnosed ranged from neonate to 35 years, the age of the patients of pediatrics ranged from neonate to 15years(mean 4.9 years), the age of the patients of internal medicine (above 16 years) ranged from 16 years to 35 years(mean 24.2 years). 3) Fifty-three(41.4%) of 128 CSF specimens were positive for enteroviruses, and 163(68.2%) of 239 stool specimens were positive for enteroviruses respectively. 4) Serotypes of 53 enteroviruses isolated from CSF were 16(30.2%) of echovirus type 30, 6(11.3%) of echovirus type 6, 1 of echovirus type 4, 4 of untyped echovirus, 1 of coxsackievirus type B5, and 24 isolates of untyped enteroviruses. Of 163 enterovirus isolated from stool were 72(44.2%) of echovirus type 30, 21(12.9%) of echovirus type 6, 1 of echovirus type 4, 17(10.4%) of undetermined subtyped echovirus, 1 of coxsackievirus type B5, 2 of A24, 3 of undetermined subtyped coxsackievirus type B, and 46 isolates of untyped enterovirus. Conclusion : There were epidemics of aseptic meningitis in the central areas of Kyoungsangnamdo from March to October 1997. The main causative organism was thought to be the echovirus type 30, and echovirus type 4, 6, coxsackievirus B5 and A24 were also thought to contribute to the epidemics.

In this study, we evaluated the impacts of land-based pollution sources on seawater and shellfish in the Jindongman area after 20.5 mm and 90.6 mm rainfall events. We analyzed sanitary indicator microorganisms used in survey management, such as total coliform, fecal coliform, Escherichia coli, and male-specific coliphage in Waste water treatment plant (WWTP), major inland pollution source,s seawater, and shellfish for 4 days after rainfall events. Our results showed that the range of coliform group and fecal coliform was 1.8-49 and <1.8-4.5 MPN (most probable number)/100 mL, respectively, after rainfall events in WWTP discharge water. Furthermore, the radius of the calculated impacted area of major inland pollution sources ranged from 5 to 798 m after 20.5 mm of rainfall and 30 to 1,031 m after 90.6 mm of rainfall. The fecal coliform of seawater at 30 stations in the shellfish growing area and areas adjacent to four stations was <1.8-130 and from <1.8-79 MPN/100 mL, respectively. The E. coli level of shellfish at 7 stations in the shellfish growing area was <18-220 MPN/100 g.
