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.

진성빈,문현욱,이광배,신용진 명지대학교 산업기술연구소 2001 産業技術硏究所論文集 Vol.20 No.-

In this dissertation, we have studied on the fabrication of Sr ferrite plastic magnet with additional Nd. First, we selected SrO5.9F₂O₃of nonstoichimatric composition as the basic composition of specimen ferrite since its magnetic property was excellent. Then, we added Nd to the specimen. In order to control the properties of the particles on fabrication of magnetic powder, 0.3wt% CaCO₃, 0.2wt% SiO₂, 0.twt% Al₂O₃and 0.5wt% Na₂SiO₃were added. For carbon coating ont he compound specimen, 5wt% polyvinylalchohol was added and then the compound specimen was calcinated under N₂environment at 1,225 ℃. After performaing grinding process for 18 hours, we obtained 1.0~1.2㎛ size of single domain magnetic powder. We added 1 wt% silane coupling and 1 wt% calcium stearate to the Sr ferrite powder with additional Nd, and then mixed them well. Next, we pelleted them after kneading them, using polyamide12 as a binder. The pelleted specimen was injection-moulded using anisotropic mould under magnetic field of 12kOe. As the results of property tests for the fabricated specimen magnet, we find that the fabricated magnet has the following excellent peroperties at Nd 12.5wt%: bHc=2.84kOe, Br=3.23kG and (BH)max=2.49MGOe.

진창남,이창훈,오상필,나오수,허문수 한국어병학회 2003 한국어병학회지 Vol.16 No.1

넙치양식시 피해가 많은 스쿠티카충의 치어기 감염경로를 규명하기 위하여 2001년도에 제주도지역 넙치양식장과 종묘배양장을 대상으로 조사를 실시하였다. 종묘생산 과정에서의 감염경로 조사를 위해 먹이생물인 클로렐라, 알테미아, 로티퍼 배양수조를 조사한 결과 로티퍼 배양수조에서 밑바닥 찌꺼기와 로티퍼 사체 및 생체에서 스쿠티카충 감염이 확인되었다. 스쿠티카충이 감염된 로티퍼를 주어에 투여한 후 자어 사육수조 바닥에는 스쿠티카충이 다량 번식하였다. 넙치 치어에 최초 감염은 부화자어가 착저 완료후 10일경 (부화후 40일경)에 사육수조 바닥에 서식하고 있던 스쿠티카충이 치어에 감염되었다. 스쿠티카충에 감염된 넙치 치어를 조직학적 방법으로 조사하여 감염경로를 확인한 결과, 안구나 뇌에 감염되는 경로는 주둥치 부분이나 등지느러미 앞부분의 표피에 감염된 후 상피조직과 근조직과 신경조직에 따라 뇌로 이행되었다. 그리고 내부장기에 감염되는 경로는 배지느러미나 뒷지느러미 연조막에 침투하여 상피조직과 근조직를 따라 항문과 직장으로 이행되었으며 비뇨생식공을 통해서 요도와 방광, 직장상피세포, 복강, 췌장, 신장외막, 신장 등으로 침투하였다. 스쿠티카충이 감염되지 않은 로티퍼를 이용하는 종묘배양장에서는 먹이생물 배양수조, 자어사육수조, 자어 및 치어 (전장 7㎝ 전후)에서 스쿠티카충이 감염되지 않았다. The infection characteristics with scuticociliates at on-land rearing farms and hatcheries of flounder, Paralithys olivaceus was investigated during they year of 2001 by juvenile infection routes. When culture tanks for living food organisms such as chlorella, rotifer, and Artemia were searched, scuticocilates were detected both in live and dead rotifer, and at the dregs of culture tank bottoms at almost hatcheries. When rotifer infected with scuticocilates fed on fish larvae, lots of scuticocilate were inhabited at the bottom of fry rearing tanks. After feeding on scuticocilates-infected rotifer on fish larvae, first infection was detected at 10 days after bottom dwelling or 40 days old after hatching. By histopathological examination we confirmed the infection route of eyeball of brain contamination was that the ciliate worms digged through mouth and front part of the dosal fin cuticle, transferred into eyeball along the epithelium and muscle tissue, and reached finally into brain by the muscle and nerve tissue. The infection of internal organs was clarified into two routes. The first route was started form the infection at ventral and anal fin rays by the worms, and reached at the anus and rectum through the epithelium and muscle tissue. The second route was initiated from the infection at urinary organ and reached into the rectum epithelium cells, inner wall of intestine, abdominal cavity, pancreas, kidney, and pancreas. At seed production farms where fish larvae fed on scuticocilate-free rotifer, the worms were not detected not only at the food organisms culture tanks and juvenile rearing tanks but also larval flounder less than 7㎝ in total length.

Background and Objectives: Maternal alcohol abuse is considered to be one of the most prominent cause of neurobiological malformations in the postnatal and adult life of the offspring. In this study, we investigated the effects of maternal alcohol drinking on the postnatal development of NPY-containing neuron, and, the influence of thyroxine treatment on the cerebral cortex and hippocampus of pups of alcohol abused mother. Materials and Method: Time-pregnant rats were divided into three groups. Alcohol-fed group A received 35 calories of liquid alcohol diet daily from gestation day 6; control pair-fed group B was fed a liquid diet in dextrin replaced alcohol isocalorically: alcohol + T4 group C received 35 calories liquid alcohol diet and exogenous thyroxine subcutaneously. Results: Group C showed prominent NPY immunoreactivity in the cerebral cortex compared to group A and B at P7. In group C, NPY-containing neurons were widely distributed in the all layers of cerebral cortex after P14. Besides, numerical decrease of NPY-containing neuron as age increases was not found in group C. However, the decrease of NPY-containing neuron was clearly observed in group A compared to group C after P14. In hippocampus, group Band C were appeared similar patterns after P7. Additionally, in group C, NPY immunoreactivity was prominently appeared in CA2 and CA3 at P14 as compared to group B. Conclusions: The present results showed the increase of intensity and number of NPY-containing neurons in cerebral cortex and hippocampus of pups of exogenous T₄ supplemented alcohol-exposed dams as compared to control pair-fed and alcohol-exposed pups at P7. It presumably suggest that NPY-containing neurons might be regulated by the early postnatal growth stimulatory effect of the exogenously supplemented T₄. Therefore, the increase of NPY synthesis caused by maternal administration of exogenous thyroxine may ameliorate fetal alcohol effect, one of the ill effects as a result of the dysthyroid state following maternal alcohol abuse.

알칼리형 연료전지(Alkaline fuel Cell, 이하 AFC)의 산소극에 사용되는 촉매를 은 염의 화학적 환원법으로 제조하였다. 그리고 최적의 전극 제조 조건을 찾기 위해 촉매의 loading량, 전극 소결 온도, PTFE함량 및 촉매 입자 크기 등이 전극의 분극특성에 미치는 영향들이 조사되었다. 연구결과에 의하면, 최적 조건은 전극 소결 온도 350℃, PTFE 함량 9wt%, 촉매의 입자크기 68㎛ 이하이었다. 한편 촉매 loading량이 증가함에 따라 전극 성능이 향상되었다. 최적의 제조 조건에서 제작된 전극은 개회로 전위 1.11V(vs. RHE),200㎷ 분극(전극전위 0.91V vs. RHE)시 전류밀도 약 0.4A/㎠,300㎷ 분극 (전극전위 0.81V vs. RHE)시 전류밀도 1.0A/㎠의 성능을 나타내었다. Doped silver catalyst used for oxygen electrode in alkaline fuel cells was prepared by reduction method of silver salt. And the effects of the silver catalyst loading, electrode sintering temperature, content of PTFE and particle size of the catalyst on the polarization characteristics of the oxygen electrodes were investigated to find the optimum preparation conditions of the electrodes. According to the results of this work, the optimum conditions were sintering temperature of 350℃, PTFE content of 9 wt% and below catalyst particle size of 68 ㎛. On the other hand, with increasing the catalyst loading, the electrode performance was improved. The electrode prepared at the optimum conditions showed open circuit potential of 1.11V(vs.RHE), current density of 0.4A/㎠ at a overpotential of 200㎷ and 1.0A/㎠ at a overpotential of 300㎷.

Surgical extrusion, immediate extrusion following tooth luxation, is a method to preserve one's natural tooth and achieve esthetic restoration without additional periodontal surgery when subgingival dental caries or crown fracture occurs. A 16-year-old male was referred to the clinic from the department of operative dentistry for the esthetic restoration of maxillary left lateral incisor. Due to the crown to root fracture, the tooth was endodontically treated with a buccal crown length of 4 mm. When the palatal flap was elevated, the mesiopalatal cervical fracture area was situated 3 - 4 mm subgingivally. Crown lengthening was achieved through surgical extrusion. After 3 months of clinical observation and provisional restoration, the maxillary left central incisor was restored with all ceramic crown and obtained a satisfactory clinical result. 치은연 하방에 치아 우식증이나 치아 파절이 발생했을 때, 치아를 탈구시켜 즉시 정출시키는 외과적 정출술을 이용한 치관 연장술은 자연치를 보존하고 추가적인 치주적 수술 없이 단기간에 심미적인 보철 치료를 가능하게 한다. 본 환자는 16세 남환으로 본원 보존과로부터 상악 좌측 중절치의 심미 수복을 위해 본원 보철과로 의뢰되었다. 상악 좌측 중절치는 근관치료가 되어 있었으며 치관-치근 파절로 인해 협측 치관 길이는 4 mm였으며 구개측 판막을 열었을 때 근심 구개측 치경부 파절 범위는 치은 하방 3 - 4 mm에 위치하였다. 외과적 정출술을 통한 치관연장술을 시행하였으며 경과 관찰 및 임시 치아의 단계를 거쳐 3개월 후에 전부 도재관으로 수복하여 만족할 만한 임상 결과를 얻을 수 있었다.

저전력 움직임 추정을 위한 VLSI 설계

문지경,소현호,김진상,조원경 경희-다반 ASIC 설계교육센터 2003 경희-다반 ASIC센터 논문집 Vol.4 No.-

Many full searchblock matching (FSBM) architectures have been proposed for the motion estimation. However, the FSBM architectures need many computations and a lot of external memory accesses which are the main source of the power consumption. We propose an efficient low-power architecture for the full search block matching (FSBM) motion estimation by eliminating unnecessary computations and data reuse. Implementation results show the proposed motion estimator can save maximally about 9.3% power dissipation than a previous motion estimator.
