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.

Poly(2-hydroxyethyl methacrylate-co-γ-methacryloxypropyl triethyl silane) 및 Poly(2-hydroxyethyl methacrylate-co-γ-methacryloxypropylmethyl bistrimethyl siloxysilane)의 반응성과 열적 성질

성용길,정태화,이상영 동국대학교 1986 論文集 Vol.25 No.-

Hydrophilic poly(2-hydroxyethyl methacrylate) has been accepted as biocompatible material for medical applications. Some of its relatively poor physical property are still remained as problems to be improved. In order to improve its physical property, new copolymers of 2-nhydroxyethyl methacrylate(HEMA) with silane monomers have been developed and synthesized. The silane monomers are γ-methacryloxypropyl triethyl silane(MPTS) and γ-methacryloxypropyl methyl bistrimethyl siloxysilane(MPMBSS). The compositions of unreacted monomers in the copolymers were separated and determined by the intensity of each peak by gas chromatographic analysis. The monomer reactivity ratios determined by the Kelen-Tu¨dos method are as follows; r_1=0.80 and r_2=0.71 for poly(HEMA-co-MPTS), r_1=1.22 and r_2=0.21 for poly(HEMA=co-MPMBSS). The tendency of alternating copolymerization and the relative reactivty of MPTS and MPMBSS with HEMA were investigated. The Q and e values were also calculated by the Alfrey-Price equation. The synthesized monomers and copolymers were identified by infrared spectroscopy and nuclear magnetic resonance spectroscopy. The thermal properties of the copolymers were also measured by thermogravimetry and differential scanning calorimetry.

Objectives : The purpose of this study was to evaluate effects of alcohol on psychomotor performance and subjective assessments in normal adults with high and low trait anxiety. Methods : The subjects consisted of 11 men in each group were tested with two doses of alcohol(0.25g/㎏ and 0.75g/㎏). Blood alcohol concentration(BAC), psychomotor performance(critical flicker fusion threshold, CFFT ; choice reaction time, CRT) and subjective assessment were measured at pre-alcohol baseline and 20, 40, 80, and 160 minutes after intake of alcohol. Results : 1) There was no significant difference in BACs between two groups at any time points after intake of each dose of alcohol. 2) After intake of 0.25g/kg alcohol, high anxiety group, compared to low anxiety group, reported less anxious and more relaxed feelings. In psychomotor performance test, however, there was no significant difference between the two groups. 3) After intake of 0.75g/kg alcohol, CFFT was increased in high anxiety group while it was decreased in low anxiety group. In subjective assessment, only high anxiety group tended to show more positive response. Conclusion : These results imply that alcohol may be more beneficial in individuals with high trait anxiety than those with low trait anxiety in terms of objective performance and subjective feelings. Furthermore, these suggest that the alcohol benefits might contribute to drinking more alcohol and frequently in individuals with high trait-anxiety.

黃龍吉,成章鉉,閔庚和 東亞大學校 大學院 1978 大學院論文集 Vol.2 No.-

To study the distribution, contents and structure of inclusion in 17Cr stainless steel, the samples were obtained with elapes time and Fe-Si addition after melted down in the high frequence induction furnace. And the distribution of inclusions, inclusion contents and the structure of inclusions were studied by means of optical microscopy, Br-Methanol method and X-ray technique. From the above experiments, the following conclusions could be summerized. 1) The inclusions of holding samples after melted down were spheroidal shape. And with the increase of holding time, the inclusion contents increased from 0.073% to 0.125%. And the distribution of fine inclusions decreased and the coarse inclusions increased from 2.0-3.ou:76% to 2.0-3.0:40%. 2) The inclusions of Fe-Si treated sample were dispersed and granular type. And the inclusion contents were increased compared with the holding samples after melted down. And the inclusions were distributed to fine one. 3) The inclusions were composed of Fe3O4, Cr2O3 and amorphous compound of Ni,Mo, Mn etc.

Although there have been many clinical studies about the facial trauma in the recent as well as in the past, severity and frequency of facial trauma are reported multifarious. It seemed to be because of variety of social, cultural, and environmental factors, and the view point of investigators. In this study, we investigated about the patients visiting emergency room during recent 4 years(2004-2007), and compared with retrospective study during former 10 years(1992-1996, 1999-2003) in Dept. OMS Pusan National University Hospital. We assessed the cause, type, demographic, etc, and analyzed alterations of facial bone fractures during past 3 periods. The results were as follows. The total number of patients was increased. 429 patients treated for maxillofacial fractures between January 1992 and December 1996, 466 patients treated between January 1992 and December 1996 and 764 patients treated between January 2004 and December 2007. The male-to-female ratio were 4.6:1, 3.9:1, and 4.16:1, respectively. Patient in the age groups of 10-19 years and 20-29 years increased in the latter two periods. Assaults and falls are decreased gradually, but slip down s are increased. Traffic accidents are still major cause of facial trauma. The mandibular fractures showed the highest incidence thorought three periods. Symphysis fractures of mandible was increased and condyle fractures of mandible was drecreased in the third period.
