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.

朱恩選,羅又禎 慶尙大學校 1986 論文集 Vol.25 No.2

The effects of refractive indices on the visibility which is an important characteristic in a Dual-Beam LDV are investigated. There are two methods for experiment; One is in the case of the variety of refractive indices of scatterers, and the other in the case of the variety of refractive indices of media. In this study, the above second method was selected in order to find that the refractive index is an important parameter on the visibility. A resistance wire with 30㎛ width and a Pt wire with 50㎛ width were applied as scatterers. Five media, ie., H2O(n=1.332), Chloroform (n=1.444), DMSO (n=1.476), Benzyl alcohol (n=1.538) and Carbondisulfide (n=1.628), were used as surrounding media. In the result, it is found that the refractive index of scatter is a parameter of the visibility.

An experiment was conducted to figure out the atomization characteristics of rice-bran oil which is a highly viscous liquid by applying ultrasonic energy to improve the atomization of spray droplets. A spray simulator, an ultrasonic system, and six different nozzles(three kinds of single hole-type nozzles and three kinds of pintle-type nozzles) were made. To investigate the effects of ultrasonic energy on the atomization of a highly viscous liquid, a phase doppler particle analyzer was used for measurement and calculation of spray droplets data. Nozzle opening pressures chosen were of 5 levels, i. e., 10 MPa, 13 MPa, 16 MPa, 20 MPa, and 24 MPa. It was observed that the application of ultrasonic energy into the highly viscous rice-bran oil was effective for the atomization improvement of the liquid fuel. With the increase of nozzle opening pressures and pin-edge angles, and with the decrease of the hole diameters, the atomization of spray droplets was improved, which conforms to general theoretical characteristics.

Early repolarization is a common electrocardiographic (ECG) feature found in young adults, men and athletes, and has been considered to be a benign feature for the last several decades. But recent studies suggest that early repolarization may be related to idiopathic ventricular fibrillation and sudden cardiac death. We report a young man, 35 years old, who had life threatening ventricular fibrillation and sudden cardiac arrest. He was evaluated for cardiac causes of ventricular fibrillation. There was no explanation other than that his ECG showed an early repolarization pattern so we treated him with implantable cardioverter defibrillator. Thus, we suggest that early repolarization may be related with life threatening ventricular arrhythmia.

Background : Communite-acquired peumonia (CAP) is one of the leading causes of mortality and morbidity. Despite progress in diagnostic techniques and treatments, management of pneumonia remains challenging, because the precise etiology remains uncertain in as many as 49% of cases. The limitaions of identifying etiologic agents make it necessary to use empiric antibiotics in almost all patients, and furthermore emergence of antibiotic-resistant organisms pose difficulties to the selection of an empiric antibiotic regimen. For the optimal choice of empirical antibiotics, we should know the frequency of etiologic agents and antimicrobial resistance rates in the community. Methods : A prospective multicenter study of community-acquired pneumonia in Korea was carried out between May 1997 and April 2000. The microbiologic diagnosis was based on the results of sputum culture, blood culture and pleural culture. Results : Five hundred eighty eight cases of community-acquired peumonia in 562 patients admitted to the hospitals. The mean age was 59.9 with male predominance (58.3%), and 370 (63%) had underlyin gillness. The etiologic agents were identified in 38.3%, and the list of individual agents, in decreasing order, was Streprococcus pneumoniae (21.7%), Klebsiella pneumoniae (14.8%) Pseudomonas aeruginosa (9.8%), Staphylococcus aureus (9.5%), viridans group streptococci (5.7%), Enterobacter cloacae (4.2%), Hemophillus Influenza (3.8%), The rates of admission to the intensive care unit was 10.4%. The motality was 7.1%. Susceptible rates of S. pneumoniae to penicillin was 36.6% and showed multidrug resistant. Forty percents of S. aureus were methicillin-resistant S. aureus. K. penumoniae were susceptible to cephalosporin and quinolone. Conclusion : In Korea, S.pneumoniae is the most important agent causing community-acquired pneumonia. Susceptible rates of S. pneumoniae to penicillin was 36.6% and showed multidrug resistant. Gram negative bacteria such as K. pneumoniae, P. aeruginosa showed high incidence when compared with that of other countries. Most of them had underlying diseases including bronchiectasis and chronic obstructive pulmonary diseases. (Korean J Infect Dis 33:1∼7, 2001)

朱廷一,李喜鳳,申哲雨 충남대학교 농업과학연구소 1999 농업과학연구 Vol.26 No.1

벼 立毛中 보리 산파재배법은 파종노력 절감, 적기파종 및 포장조건 불량시 대체파종 등의 장점이 있지만 관행에 비하여 수량성이 낮고 연차간 變異가 큰 특징이 있다. 수량성을 향상시키기 위하여 栽培安定性을 높이는 관리기술이 요구되는데 우선 입모 확보와 둑새풀 방제체제 확립이 절실히 요구된다. 따라서 立毛率 향상시킬수 있는 요인, 다수확을 위한 적정 입모수 설정 및 둑새풀에 의한 감수정도 등을 구명코자 대전에서 올보리를 공시하여 벼 수확 1일전에 파종하고 이에 대한 결과는 다음과 같다 . 1. 볏짚피복과 진압에 의하여 출현율이 향상되었는데 볏짚피복효과가 진압효과에 비하여 높았고 추가진압으로 11% 증수 효과를 기대할 수 있었다. 2. 단위 면적당 적정보리 立毛數는 507개/㎡로 측정되었다. 3. 둑새풀 발생이 많을수록 수량이 감소되었는데 ㎡당 17~22본 발생시 21.8%, 6~11본 발생시 11.0%가 각각 감수되었다. This experiment was carried out to estimate the appropriate seedling stand and to find out the factors of good establishment and the reason of the reduction of yield by water foxtail. The seedling stands was improved by the ice straw mulching and treading by the tracks of combine. The effect of mulching was higher than the treading. The appropriate seedling stands for example yield were estimated about 507 plants per ㎡ and its yield was 24㎏/10a. The higher density of water foxtail, the less the grain yield; 21.8% by 17 to 22 water foxtail stands per ㎡ and 11.0% by 6 to 11 plants.

The relative density seems to be important as a factor of controlling the physical properties in the case of cohesionless soil ground as sand. Therefore, the study is more important about the method for reappearing he same relative density when the specimen of shearing test is to be produce or the model test of ground is to made. In this study, the apparatus making use of the multiple sieving pluviation method-one of the reappearance of relative density-could be made. Using this apparatus, tests were practiced varying the factors such as the size of sieve mesh and the number of sieve, the amount of falling discharge, the falling height etc. about the standard sand in Jumunjin and Hadong sand. When laboratory test is perfomed by the cohesionless soil, it presents the method for reappearing of the relative density in field.
