The author has reviewed 16 HIV infected individuals who visited emergency center. The results were as follows; 1. In view of sex, age distribution, and clinical state, most of the patients managed in emergency room were known HIV infected patients, and they were in progressed state to AIDS. 2. The symptom, and sign were nonspecific in most of the patients. 3. In view of sex, age distribution, course of infection, clinical state, and other foreign report, patients who visit emergency room have proportionaly high incidence of HIV infection to general population. Therefore, systemized effort is needed to detect, and manage them.

A theoretical study was carried out on the prediction of drop size distribution of the pressure swirl atomizer. Drop size distribution was obtained by using maximum entropy formalism. Several constraints in the form of the definition of mean diameter were used in this formulation in order to avoid the difficulties of estimating source term. In this study D10 only was introduced the formulation as a constraint. This drop size obtained by using linear Kelvin-Helmholtz instability theory was considered as an unknown characteristic length scale. As a result, the predicted drop size distribution was agreed well with experimental data measured with Malvern 2600.

In this study, the classified researches the artificial and natural flaws in welding pails are performed using the pattern recognition technology. For this purpose the signal pattern recognition package including the user defined function was developed and the total procedure including the digital signal processing, feature extraction, feature selection and classifi-er selection is treated by bulk. Specially it is composed with and discussed using the statistical classifier such as the linear discriminant function the empirical Bayesian classifier. Also, the pattern recognition technology is applied to classifica-tion problem of natural flaw(i.e multiple classification problem - crack, lack of penetration, lack of fusion, porosity, and slag inclusion, the planar and volumetric flaw classification problem). According to this results, it is possible to acquire the recognition rate of 83% above even through it is different a little according to domain extracting the feature and the classifier.

The evaluation of patients with microscopic hematuria after blunt abdominal trauma has become controversial. We tested the hypothesis that renal contusion can be diagnosed clinically and that these patients do not require radiographic evaluation. To evaluate the association of microscopic hematuria without shock and with renal injury, we reviewed the medical records of 252 patients following blunt abdominal trauma. Microscopic hematuria without shock was noted in 58 of 252 patients. Of the 58 patients 52 had renal contusion, 4 had renal laceration, 1 had a renal rupture and 1 had renal pedicle injury. All of the patients with renal contusions experienced no complications from nonoperative management. But, avoiding a radiopraphic evaluation in patients with blunt renal trauma plus microscopic hematuria and no shock would miss a few cases of severe renal injury.

Prevertebral soft tissue swelling of cervical spine lateral radiogram is well known as an indirect evidence of occult cervical spine injury. But the clinical and statistical value of it has been of debate. We tried to analyse the value of cervical prevertebral soft tissue width as a screening test for cervical spine injury by comparison of two categorized study groups; the control group, traumatized patients without cervical spine injury and the injury and the injury group, traumatized patients with bony cervical injury. The injury group consisted of patients admitted between September 1993 and December 1994 with an ED diagnosis of bony cervical injury. The control group consisted of patients admitted between January 1994 and June 1994 who received cervical spine lateral radiograph because of suspicion of cervical spine injury or as a routine check. In both group, we sampled the patients who received cervical spine lateral rediograph within 24 hours after injury and excluded the patients less than 15 years old and more than 65 years old, In the control group, we confirmed the patients had no problem in cervical spine of follow-up. 101 control patients and 68 injury patients were identified. The injury group was further divided into two subgroups: those with injuries at C1-C3 to the upper injury subgroup and those with injuries at C4-C7 to the lower injury sub group. The prevertebral soft tissue widths of injury group were larger than of control group at C2(mean 6.1mm versus 4.5mm) and also at C6(mean 13.4mm versus 11.2mm). Especially upper injury subgroup had quite large value of C2 prevertebral soft tissue width(mean 14.1mm). Nevertheless, both in C2 and C6, there is no cutoff value with acceptable sensitivity and specificity as a screening test. But the 7mm at C2 and 14mm at C6 had high specificity(90%) and were thought to be a good radiologic indicators of further evaluation.

Changes in Interhospital Transfer Patterns of Acute Ischemic Stroke Patients in the Regional Stroke Care System After Designation of a Cerebrovascular-specified Center

Cho, Suck Ju,Sung, Sang Min,Park, Sung Wook,Kim, Hyung Hoi,Hwang, Seong Youn,Lee, Young Hwan,Cho, Jung Hong Chonnam National University Medical School 2012 CMJ Vol.48 No.3

<P>The Ministry of Health and Welfare of Korea recently designated cerebrovascularspecified centers (CSCs) to improve the regional stroke care system for acute ischemic stroke (AIS) patients. This study was performed to evaluate the changes in the flow of AIS patients between hospitals and to describe the role of the Emergency Medical Information Center (EMIC) after the designation of the CSCs. Data for coordination of interhospital transfers by the EMIC were reviewed for 6 months before and after designation of the CSCs. The data included the success or failure rate, the time used for coordination of interhospital transfer, and the changes in the interhospital transfer pattern between transfer-requesting and transfer-accepting hospitals. The total number of requests for interhospital transfer increased from 198 to 244 after designation of the CSCs. The median time used for coordination decreased from 8.0 minutes to 4.0 minutes (p<0.001). The success rate of coordination increased from 88.9% to 96.7% (p<0.001). The proportion of requests by CSCs decreased from 3.5% to 0.4% (p=0.017). However, the proportion of acceptance by non-CSC hospitals increased from 15.9% to 25.8% (p=0.015). With the designation of CSCs, the EMIC could coordinate interhospital transfers more quickly. However, AIS patients are more dispersed to CSC and non-CSC hospitals, which might be because the CSCs still do not have sufficient resources to cover the increasing volume of AIS patients and non-CSC hospitals have changed their policies. Further studies based on patients' outcome are needed to determine the adequate type of interhospital transfer for AIS patients.</P>

조석주,염석란,정진우 대한응급의학회 2003 대한응급의학회지 Vol.14 No.1

Purpose: The purpose of this study was to use a review of the regional disaster that occurred on April 15, 2002, to improve the National Disaster Medical System and to operate the Disaster Medical Assistance Team and the Mobile Emergency Support Unit better. Methods: We retrospectively analyzed 39 survivors among the 167 victims of the Air China aircraft crash, Kimhae, Korea, on April 15, 2002, by using reports of the on-site disaster medical assistance team members, recordings of notifications to the Busan and the Kyoungnam 1339 Emergency Information Centers from the scene of accident, and medical records of the victims transported to hospitals. Results: On the date of accident, April 15, 2002, 27 of the 39 survivors were transported to 5 hospitals in Kimhae and 12 were transported to 8 hospitals in Busan. On the next day, April 16, two patients who had been transported to hospitals in Kimhae were transferred to medical centers in Busan. One of them expired, and the other was subsequently transferred to a medical center in Seoul and expired on May 2, 2002. Conclusion: Still now, our National Disaster Medical System contains many problems, especially lack of cooperation between related parts, and insufficient communications. This study shows that we should recheck our National Disaster Medical Dystem and construct a cooperative Police. Fire defense organization, 1339 emergency Medical Information Center, and regional medical service system.
