Background : To assess the current level of development of emergency medicine (EM) systems in Asia. Method : Survey of EM professionals from 12 Asian countries during a 90-day period from August to November 1998. 12 EM professionals from 12 Asian countries completed the survey. All participants were physicians. 7 participants (58%) gave presentations at an international EM conference during the study period. Respondents completed a 103 question questionnaire about the status of EM specialty, academic, patient care, information and management systems and the factors influencing the future of EM in their countries. Results : 92% of respondents stated that their countries have hospital-based emergency departments (ED). More than 80% of respondents reported that their countries have EMS systems and ED systems for trauma care and patient transfer. More than 70% stated that their countries have national EM organizations, EM research, national EMS activation phone numbers, ED systems for pediatric emergency care, emergency physician (EP) training in ACLS and ATLS and peer review. More than 60% reported official recognition of EM as an independent specialty status, ED triage systems and systems for customer service. More than 50% reported EM residency training programs, EM journals and EP ability to perform rapid sequence intubation (RSI). 50% reported EP ability to perform thrombolysis for acute MI and 33% reported EP ultrasonography. 92% felt that a lack of funding posed a moderate or great obstacle to the future development of EM in their countries. Conclusions : Many essential systems of EM now exist throughout Asia. In the systems of administration and emergency medical information in many countries, there are some parts to be developed further.

정용재,한태성,최성부,남석태,김병식 동국대학교 산업기술연구원 1996 산업기술논문집 Vol.8 No.-

Pyromellitic dianhydride(PMDA) 와 Oxydianiline(ODA)를 N, N-dimethylacetamide (DMAc)에 녹여 Polyamic acid(PAA)를 2단계 열이미드화법으로 제조하였다. 제조된 폴리이미드 막의 이미드화도는 FT-IR에 의하여 분석되었다. 또한 PAA의 농도를 10~30wt%로 변화시키며 합성하여 열이미드화 시킨 후 농도에 따른 단면의 상태를 SEM사진을 통하여 관찰하였다. 농도 변화에 따른 밀도와 T_g의 변화는 혼합액체부상법과 DSC로 분석되었다. 열처리 온도를 증가시킬수록 이미드화도는 증가되었고 PAA의 농도가 증가할수록 필름의 단면이 치밀해짐을 알 수 있었다. 또한 제조된 PMDA-ODA 폴리이미드의 T_g는 215℃ 이었다. Polyamic acid(PAA) was synthesised with Pyromellitic dianhydride(PMDA) and Oxydianiline (ODA) in N, N-dimethylacetamide(DMAc). PMDA-ODA polyimide membranes were obtained by two step thermal imidization, and the degree of imidization of polyimide membranes was observed by the FT-IR. After the thermal imidization through the concentration of varied synthesis of PAA, 10~30wt%, SEM photographies of section state were observed. The density and glass transition temperature on the varied concentration were replace with investigated test of density and Differential Scanning Calorimetry (DSC). With increasing thermal treatment temperature, the degree of imidization was increased. While the concentration of PAA increases, the section of membrane was densed. The glass transition temperature was maintained to be constant(215℃) within the PAA concentration range.

전산화 신경인지기능 검사를 이용한 외상성 두뇌손상환자의 신경인지기능평가

정인원,최인석,김재진 大韓神經精神醫學會 1998 신경정신의학 Vol.37 No.2

뇌영상검사상 국소적인 병변을 보이지 않는 경도 외상성 두뇌손상환자를 대상으로 한 신경인지기능검시에서 인지기능결함이 보고되고 있으며 이에 대하여 객관적인 인지기능장애 평가도구가 요구돼 왔다. 본 연구에서는 외상성 두뇌손상환자들을 대상으로 뇌 영상검사를 시행하여 국소적인 병변의 유무에 따라 병변군과 비병변군으로 분류하였으며, 이와 동시에 신경인지기능검사를 시행하여 병변의 유무에 따른 Bender-Gestalt Test, 표준도형검사, 인식력검사. 신호탐지검사 결과를 비교해 보았다. 또한 KWIS 지능지수와 표준도형검사 지능지수간의 상관관계를 조사하여 지능검사도구로 표준도형검사의 유용성을 알아보고자 하였다. 외상성 두뇌손상환자집단의 신경인지기능검사 결과는 다음과 같았다. 1) 신경정신과적 주요 증상 비교에서 병변군은 인지장애 호소가 맡았으며. 비병변군은 신체장애 호소가 많았다. 2) BGT 전체수행오류는 병변군이 비병변군보다 많았다. 3) KWIS 지능검사상 병변군과 비병변군간의 차이는 없었다. 4) 표준도형검사 소항목 검사결과 병변군은 정상대조군이나 비병변군에 비하여 난이도가 높을수록 수행이 낮았다. 5) 인식력검사 결과 병변군은 정상대조군보다 수행이 낮았다. 6) 외상성 두뇌손상환자집단에서 표준도형검사 지능지수는 KWIS 지능지수와 r=0.67의 높은 상관관계를 보였다. . 이와 같은 결과로 외상성 두뇌손상환자 중 병변군은 공간구성능력, 미세운동협응능력. 형태기억능력, 반응속도에서 장애를 보임을 알 수 있었다. 통계적인 의미는 없었으나 인식력검사결과에서 비병변군은 정상대조군과는 다른 반응 경향을 나타내고 있었다. 인식력검사상 비병변군의 이러한 차이는 비병변군이 신체장애를 주로 호소하였고. 경도 외상성 두뇌손상에서 보상과 같은 심리적 요인들이 증상의 유지에 기여할 수 있다는 보고를 고려할 때. 신경인지기능검사의 임상적,인 해석에 주의를 요하고 있다. 그리고 외상성 두뇌손상환자에서 표준도형검사 지능지수와 KWIS 지능지수는 정상대조군보다 높은 상관관계를 보여 표준도형검사는 두뇌손상환자와 같이 지적능력이 저하된 진단에서 KWIS 지능검사를 보완할 수 있는 유용한 지능검사로 임상상황에서 경제적이고 객관적인 지능검사 도구가 될 수 있음을 알 수 있었다. Irrespective of focal lesion in brain imaging study, the deficits in cognitive function have been reported in mild traumatic brain injury patients. Therefore, they have been asked sensitive and objective assessment tools measuring cognitive deficits. In this study, traumatic brain injury patients were classified into lesion group and non-lesion group by presence of focal lesion in brain imaging study At the same time, Results of Bender-Gestalt test, Standard Progressive Matrices, Cognitrone, and Signal Detection were analyzed among the groups. We assessed usefulness of Standard Progressive Matrices as assessment tool of intelligence in traumatic brain injury patients by correlation coefficients between KWIS and Standard Professive Matrices intelligence quotients. 1) Most lesion group showed severe deficits in cognitive function, and most non-lesion group showed severe somatic symptoms. 2) The lesion group showed higher Bender-Gestalt test total error score than non-lesion group. 3) There was no difference in KWIS intelligence quotients between lesion and non-lesion group. 4) The lesion group showed lower performance than normal control and non-lesion group as increasing complexity of Standard Progressive Matrices subset. 5) The lesion group showed poor performance than normal control group in Cognitrone. 6) There were higher correlation coefficients than normal control group between Standard Progressive Matrices intelligence quotients and KWIS intelligence quotients in traumatic brain injury patients. According to the above results, lesion group showed deficits in space-construction ability, fine-motor coordination ability, form-memory ability, and delayed response-time. Although there are no statistical significance, comparing with normal control group, non-lesion group showed different response-trend in Cognitrone. Considering somatic symptoms in most nonlesion group and contribution of psychological factors in maintenance of symptoms in mild traumatic brain injury patients, the differences in Cognitrone must be interpreted carefully. These result suggest than Standard Professive Matrices can be a useful tool for assessment of intelligence in traumatic brain injury patients who showed deficits in cognitive function.

The purpose of this study was to evaluate the effects of commercial home tooth bleaching agent application on the color of esthetic restorative materials. In order to evaluate the effect of intraoral aging of these materials(3 composite resins; Palfique Estelite??, Prodigy??, TPH Spectrum??, and 1 compomer ; Dyract??) on the degree of lightness change induced by tooth bleaching agents, each material groups were subdivided (thermocycled and non-thermocycled). Three specimens from each material group were treated with 5 types of bleaching agents (Nite White Excel??, Insta-Brite??, Opalescence??, Plus White?? and StarBrite Contrast_EM??) and evaluated. The results were as follows: 1. Bleaching agent treatments applied to esthetic restorative materials which were not thermocycled before the treatment induced various ΔL^* values as low as lesser than 1 and as high as greater than 4. On the other hand, the second material group (thermocycled before bleaching agent treatments) induced ΔL^* values lesser than 2, except in the case of Insta-Brite treated Dyract group. 2. In the grups that were thermocycled before bleaching agent treatment, Prodigy showed the lowest increase in L^* by all the bleaching agent treatments. Conversely, Dyract demonstrated a higher increase in L^* than the other esthetic restorative materials by Insta-Brite, Opalescence, Plus White bleaching agent treatments. 3. In the groups that were not thermocycled before bleaching agent treatment, Prodigy showed a lower increase in L^* when treated with Nite White Excel, Insta-Brite, Opalescence. On the other hand, TPH Spectrum displayed a higher increase in L^* except when treated with Plus White. These results demonstrated that all commercial tooth bleaching agents have appreciable bleaching effect on teeth, and induces color changes on restorative materials to varying degrees depending on the combination of restorative material and the tooth bleaching agents. More caution should be taken concerning these effects in the case of recently restored esthetic materials.
