Patients die in the emergency department frequently ; however, there has been little about the incidence and cause of Emergency Department death in the emergency medicine literature. This study was conducted retrospectively to gain insight into the patients who die suddenly and unexpectedly in the Emergency Department(ED). A total of 360 patients were pronounced dead in the ED from 1991 through 1994 in Chung Ang Gil Hospital. Of the 360 patients, 309 (86%) were brought to the ED with cardiopulmonary resuscitation in progress or as do not resuscitation(DNR) patients, leaving 51(14%) patients who met the unexpected death criteria. Of the unexpected deaths, 32(62.7%) patients presented to the ED with either abnormal vital sign (24 of 32) or some alteration in consciousness (18 of 32), or both of them (10 of 56). Medical and surgical causes of death represented 47.1% (24 patients) and 15.6% (8 patients) of the unexpected deaths respectively. Trauma represented 19 (37.3%) of the unexpected deaths, with 14 of these being the result of motor vehicle collision. The yearly incidence of unexpected ED death is presented in numbers of deaths per 10,000 ED visits. In 1991, the incidence was 3.4, and in 1992, 1993 and 1994 those were 2.7, 2.2 and 2.1 respectively.

During mid­loop operation of nuclear power to prevent the residual heat removal system from failure due to air entrainment of free surface vortex in the piping system a set of simulating experiments was performed. Through these experiments, a relation between the non­dimensionalized numbers, such as submergence H/d. Froude number, Reynolds number, was found. However, the effect of the Reynolds number is not so dominant as that of the Froude number. It was also found that the boundary conditions of the free surface, that is, the perturbation of the free surface due to opening of closing pump and valves have significant effects on the free surface vortex. Futhermore a modified inlet device which reducer type with vortex breaker has strongly been recommended for the prevention of air entrainment.

적외선 흡수 분광법을 이용하여 경수 (H_(2)O) 속에 존재하는 수십 ppm 정도의 중수(D_(2_)O)를 정량하는 분석 방법을 개발하였다. 이 방법은 원자력 발전소의 경수로에서 동위 원소로 변형된 중수의 양을 정량하는데 이용될 수 있을 것으로 기대된다. Infrared absorption spectroscopy has been utilized to demonstrate its feasibility for monitoring the quatitative amount of heavy water at ppm level. This analytical method can be applied to measure the amount of heavy water in the light water cooling system of nuclear power plant.

The development of Shadow Moire in many kinds of methods for acquiring 3-dimensional information from an object is written in this paper. The fringe is appeared, when a grating mask makes its shadow on the object. The object is moved along x-axis more then 3 times to get phases from its fringe that contains data of the object's height. PMP(Phase Measuring Profilometry) is used for analyzing these images from a CCD camera. The calculated phase is remedied for expending the restricted results due to range of the tan^(-1).

콘택트렌즈 보존 용기 유래 가시아메바 KA/L5주의 세포질 내에 존재하는 bacterial endosymbiont(내공생세균)를 투과전자현미경으로 관찰하여 확인하였다. 숙주인 가시아메바 KA/L5주는 형태학적으로 제2군에 속하였고, rDNA PCR-RFLP 결과 A. lugdunensis로 동정되었다. 미토콘드리아 DNA RFLP와 동위효소 분석상 이 충주는 국내 콘택트렌즈 보존용기에서 가장흔히 분리되는 type인 KA/Ll주, 국내 임상 분리주 중 하나인 KA/E2주, 내공생세균을 가지는 것으로 보고된 병원 냉각수 유래 KA/W4주 및 L3a주와 동일하거나 매우 유사한 성적을 보였다. 내공생세균은 약 1.38× 0.507㎛의 크기였고, 아메바 세포질 내에 불규칙하게 분포하고 있었으며. 그 표면에 아메바의 ribosome이 부착되어 있었다. 내공생세균을 둘러싼 lacunae나 막과 같은 구조는 관찰되지 않았다. Legionella 특이 primer를 이용한 효소중합반응(PCR)에서 내공생세균의 염색체 DNA는 증폭되지 않았다. A. lugdunensis의 우리말 이름을 담수가시아메바로 제안한다. Transmission electron microscopy of an Acanthamieba isolate (KA/L5) from a contact lens case revealed bacterial endosymbionts within cytoplasm of the amoebae, The Acanthamoeba isolate belonged to the morphological group II. Based on the polymerase chain reaction (PCR) - restriction fragment length Polymorphism (RFLP) of 18S ribosomal RNA coding DNA (rDNA), the Isolate was identified as A. lugdunensis. Strain typing by isoenzyme analysis using isoelectric focusing (IEF) and mitochondrial (Mt) DNA RFLP revealed that the isolate was closely related with KA/Ll , the most predominant type of isolates from contact lens storage cases, KA/E2, a clinical isolate, KA/W4, preciously reported to host endosymbionts, and L3a strains of A. lugdunensis. The endosymbionts were similar to those of KA/W4 In aspects that they were randomly distributed in both trophozoites and cysts, and were rod-shaped bacteria measuring approximately 1.38x 0.50㎛. But the number of endosymbionts per amoeba was significantly lower than that of KA/W4. They were neither limited by phagosomal membranes nor included In lacunae- like structure.

<P><B>Objective</B></P><P>The purpose of this study was to develop a scale to measure motivation for smoking cessation. Motivation is known to be important for success of smoking cessation. The reliability of the scale was assessed and its predictive validity for smoking cessation was evaluated.</P><P><B>Methods</B></P><P>We recruited 333 men aged 20 to 70 that visited smoking cessation clinics at seven public health centers. The demographic characteristics were recorded and the Korean version of Stages of Readiness for Change and Eagerness for Treatment Scale for Smoking (K-SO-CRATES-S) performed. A smoking cessation motivation scale was developed with 10 questions based on the theory of motivation enhancement therapy.</P><P><B>Results</B></P><P>The motivation scale was composed of four subscales based on the factor analysis; each subscale had an adequate degree of internal consistency. In addition, the newly developed scale had a high degree of validity based on its significant correlation with the smoking version of SOCRATES. Moreover, the precontemplation level of motivation was found to significantly predict the success of smoking cessation. And one of the subscales of the Korean Nicotine Dependence Syndrome Scale (K-NDSS), stereotypy which also significantly predicted the success of smoking cessation, significantly correlated with the preparation 1 and 2 level of motivation.</P><P><B>Conclusion</B></P><P>The smoking cessation motivation scale with 10 questions that was developed in this study was a highly reliable and valid scale for the prediction of success for smoking cessation for those who wanted to stop smoking.</P>
