We report a case of tsutsugamushi disease in a 26 year-old pregnant woman who was treated with azithromycin. Her gestation period was 27 weeks and she admitted with fever, rash, and eschar on the right shoulder. Currently recommended medications for the treatment of scrub typhus are doxycycline or chloramphenicol. But, these drugs are class D drugs according to the U.S. Food and Drug Administration (FDA) Fetal Risk Summary, so they couldn't be used to treat pregnant women. Recently, a few case reports suggested that azithromycin, a relatively new macrolide antibiotic, was effective and safe for the treatment of scrub typhus in pregnant women. And, there is no evidence that azithromycin causes harmful effects to the developing fetus or to children. On the basis of current in vivo test that confirms the effectiveness of azithromycin, it may be the drug of choice for the treatment of scrub typhus in pregnant women and children.

서정필,박준석,황태식,장석준,김승호 대한응급의학회 2000 대한응급의학회지 Vol.11 No.3

Background: Ketamine use in emergency room has been increased. It has rapid onset of action and appropriate duration of action. It does not need endotracheal intubation and produces potent analgesia, sedation, and amnesia. The object of this study is to determine the safety and the degree of physician's satisfaction in relation to ketamine use. Materials and Methods: This is a prospective study using protocol. Pediatric trauma patients who need sedation were given IM ketamine(4 ㎎/㎏) and atropine(0.01 ㎎/㎏) in a same syringe. Monitoring of patients was done by EM residents and complications of ketamine use were recorded. Physician's satisfaction was also recorded after the procedure. Results: Intramuscular ketamine was administered 54 times, mainly for laceration repair. Physicians completed protocol for 51 of treated children. The median time for onset of sedation was 6.5±2.4 min, and duration of action was 32.4±10.8 min. Hypersalivation occurred in 9.8%(n=5); random movement 3.9%(n=2), emesis during procedure(n=1), emesis at home(n=1), and transient oxygen desaturation(n=1). All were quickly identified and treated without specific airway management and sequelae. Of 84% of physicians was satisfied with ketamine use for pediatric sedation. Conclusion: Intramuscular ketamine can be administered safely and satisfactorily in emergency room to facilitate pediatric procedures in conjunction with a defined protocol and appropriate monitoring.

문화취향이 정보 불평등에 미치는 영향

서우석,이호영 한국정보사회진흥원 2006 정보화정책 Vol.13 No.3

인터넷을 이용한 문화콘텐츠 소비가 증가함에 따라 정보화 과정에서 문화취향이 중요한 요인으로 작용하게 되었다. 이 연구는 정보 불평등에 대한 문화취향의 영향을 이론적으로 규명하고 경험적 자료의 분석을 통해 실증하고자 하였다. 이론적인 논의에서는 정보부자와 정보빈자 사이의 간극에 대한 관심으로부터 출발하였던 정보격차의 문제가 정보화의 진전에 따라 다차원적인 양상을 갖게 되면서 사용격차가 갖는 의미가 커졌음을 제시하였다. 또한 인터넷 사용에 대한 기대편익과 충족감의 순환구조를 통해 인터넷의 사용격차가 구조화될 때 문화취향에 따른 네트워크 효과가 중요한 변수로 작용할 수 있음을 논의하였다. 서울시민을 대상으로 수집한 경험적 자료를 이용하여 분석한 결과 문화취향은 인터넷 이용정도, 인터넷 글쓰기, 인터넷 기대편익에 모두 유의미한 영향을 미치는 것으로 나타났다. 이러한 결과는 정보 불평등을 해소하기 위해서 소외 계층이 정보화로 얻을 수 있는 만족과 기대 수준을 높이는 방향으로 정책이 추진되어야 하며 이를 위해서 소외 계층의 문화취향을 고려한 부처간 협력사업이 필요함을 시사한다.

최근 몇 년 사이에 인터넷(Internet) 공간상에서 거래되는 선박 매매 사이트의 출현으로 인하여 사이버해운거래 시장이 형성되고 있다. 인터넷은 다양한 정보제공자에 의해 광범위한 분야의 정보를 멀티미디어 형태로 전달한다는 점에서 매우 각광을 받고 있지만 이용자의 증가로 무수한 정보들이 걸러지지 못한 채로 Web상에 존재하게 되었다. 따라서, 이러한 정보들을 체계적으로 정리하고, 이용자들의 구미에 맞게 가공된 정보의 필요성이 대두되게 되었다. 이러한 문제를 해결하기 위해서 이용자가 원하는 것을 스스로 인지하고 판단하여 요구사항을 해결해주는 "지능적 대리인" 또는 "지능을 가진 도우미"라고 일컫는 지능형 에이전트(Intelligent Agent)의 필요성이 대두되었다. 지능형 에이전트는 그 다양한 기능으로 인하여 인터넷에서 매우 중요한 요소로 자리잡게 되었다. 우리나라를 비롯해서 선진 해운국에서는 선박매매사이트를 개설하여 사이버 공간상에서 거래를 수행하고 있지만, 사이트별 등록된 선박의 수가 많지 않을 뿐 아니라 거래대상 선박의 표현 방식도 사이트별 국가별로 매우 달라, 선박 매매 시 충분한 매매 대상 선박정보를 획득하기 어려운 실정이다. 본 연구는 선박매매 시 고객에게 매매 선박정보를 제공해주는 선박매매용 에이전트 설계를 목표로 하고 있다. Bargainfinder, Bargainboat, Shopboat, Price watch 등 쇼핑몰을 대상으로하는 비교쇼핑에이전트는 상용화되어 운영되고 있지만 선박매매용 에이전트에 관한 연구는 시도되지 않고 있다. 본 연구는 선박매매용 에이전트를 개발하기 위한 설계연구로서 다음 사항에 대한 연구가 시도되었다. (a) 구매 선박에 대한 요구? 표현 방법 (b) 관련 선박의 표현, 등록 및 색인방법 (c) 공급 선박의 분류와 표현 방법 (d) 에이전트의 정보 수집을 위한 메시지 표현방법 (e) 수집된 선박정보의 데이터베이스 (f) 요구 선박을 찾아주는 정보제공 서비스가 요구된다. The IT for e-Business performance is composed of the financial performance of a corporation, the effectiveness of IT itself, the suitability of processes and so forth. For the last 30 years many studies about IT evaluation have been conducted, most cases have been measured inclusively in terms of technology level, information level, functional level and management level. However these management oriented evaluation models are too narrow to evaluate IT for 3-Business. The IT in a corporation needs to be measured broadly. Corporate performance of IT needs to use models in the past and concentrate on environmental characteristics. This study intends to find more practical IT evaluation models for e-Business. We found two standardized IT process evaluation models, CMM and SPICE which are analyzed in terms of process in an organization. Afterwards this study will suggest an appropriate conceptual model for evaluating IT for e-Business.

In modelling seismic isolation systems, the flexibility of the bearing must be modelled correctly so that the period shift is reflected in the results and the model must reflect the reduction in response caused by the hysteretic damping. In the study, the lead rubber bearing(LRB) were each modelled as cantilever beam element at the bearing locations and reduction in response caused by the hysteretic damping was involved by composite spectrum modified the caltrans ARS spectrum curve. The comparison between the LEADeR program and the MIDAS results demonstrates that the values obtained from the modeling are sufficiently accurate to access the benefits of the seismic isolation scheme.

徐好錫 건국대학교 1989 장안지리 Vol.4 No.4

The purpose of research in this paper is to achieve adequate distribution of water in the plan of utilizing groundwater for irrigation by selecting important factors that greatly influences water-balance of groundwater in irrigated area and researching into mutual relations among those factors. Even though there have been many researches on the whole water-balance, there are still few researches on it within the area of an alluvial layer. Therefore, it is necessary to reveal the water-balance of ground-water in an alluvial layer by means of analizing into each factor of water-balance. As the method of research, 1 applied my own newly adjusted formula with the selected factors that are liable to influence the water-balance of the area in these researches through examining the water-balance formula in common area and that of irrigated area. The factors that influences water-balance are as follows :precipitation, evaporation, the amount of ground water reservoir, and so on. The amounts of precipitation from 1985 to 1987 were quoted from the date in Ichon's auxiliary Station of Meteorological Observatory, the amounts of evapotranspitation were calculated with that of the surface of paddy leaf for the research area belonging to paddy fields. And to measure the amount of groundwater reservoir, 7 wells were selected ailed at each well once a week ground water level, depth of well, temperature of water, and PH. were measured. The Results of analizing this research ale as follows: a) The actual storage amounts of outflow in irrigated area is 397mm when marked by water column, and it is equal to 19 percent of the whole amounts of outflow in the area. b) It turned out that ground-water is more important water resources than precipitation in industry within the research area. c) The storage of groundwater from precipitation and inflow did not flow out to other area and was mostly utilized in irrigation. It comes to the conclusion that when the said my newly adjusted formula based on water-balance formula by Siline-Bekcourine for all factors in the research paddy area, goundwater has significant utility as agricultural water resources in irrigated area containing an alluvial aquifer. Therefore, if there is an alluvial aquifer within any irrigated area in our country, Korea, in analizing any water-balance, I dare say that it may be available to apply the water-balance formula induced from this research.
