Purpose: The aim of this study was to evaluate the characteristics and the prognostic factors of carbamate poisoned patients who visited emergency departments. Methods: From August 2005 to July 2006, we investigated the demographic feature, dose of exposure, time of exposure, alcohol intake, route of exposure, reason of exposure, site of exposure, pre-existing medical condition, time from exposure to emergency department (ED), transfer from other hospitals, vital sign at ED arrival, symptom or sign at ED arrival, and result of care of the patients who visited the ED of thirty-eight hospitals in Korea. According to the result of care, we divided the patients into two groups, the survival and the dead. To evaluated the prognostic factors, we calculated the odds ratio of each factor for the survival. Results: Among the sixty-eight patients, fifty-five patients (80.9%) were survival and thirteen patients (19.1%) were dead. The patients in the dead were older than the patients in the survival. The Glasgow coma scale (GCS) of the patients in the dead was lower than the GCS in the survival. The odds ratio of the GCS at ED arrival for the survival was 1.58 (95% CI; 1.23-2.05). Other factors showed no statistical significances. Conclusion: The GCS at emergency department arrival was the prognosis factor of the carbamate poisoned patients who visited emergency departments. If the carbamate poisoned patients showed altered mentalities, they should be provided intensive care, immediately.

There are increasing demands for the producing and breeding new domestic riding horses for the vitalizations of horse riding industry in Korea, according as 'Horse Industry Support Act' became. In this study, we were to develop the functional relation through the conformation comparison & body composition analysis. 76 heads of 5 breeds utilized for riding horses in Korea were used and their body measurements on 12 items were measured and cluster analysis was conducted to determine the correlation relation among them. The measurements were standardized that (height, croup height, pelvis length), and (hip width, width of pelvis) were highly correlated. In these results of the decision tree, we confirmed to classify the breed type determination by their body measurements (hip height, hip width, head length, croup height). This result can be used as basic data for the development of horse type determination (racing, riding, Riding for the Disabled, Working, or fattening) through the analysis of body composition, and be utilized as the basic data for the producing and breeding new domestic riding horses through the 3D Stereosocpic image system analyze.

무선 이동 애드 혹 네트워크를 위한 동적 그룹 소스 라우팅 프로토콜

이동 애드 혹 네트워크에서는 노드의 이동성으로 인해 설정된 라우팅 경로를 안정적으로 유지하는 것이 어렵다. 본 논문에서는 사실상의 복수 경로를 의미하는 그룹경로를 사용하여 경로 안정성을 높인 그룹 소스 라우팅 프로토콜을 제안한다. 물리적으로 인접한 노드들끼리 클러스터 (혹은 그룹)를 형성하며, 각 클러스터는 모든 멤버들을 직접 연결하는 클러스터헤드와 클러스터를 유일하게 식별하기 위한 클러스터 레이블을 갖는다. 그룹경로는 소스에서 목적지까지 놓여있는 클러스터들의 레이블 시퀀스로 이루어진다. 그룹경로상의 각 클러스터에 속한 노드들은 클러스터들을 잇는 브릿지 노드들을 통해 그룹경로상의 다음 레이블을 갖는 클러스터의 노드로 패킷을 전달한다. 따라서, 그룹경로는 단일 링크 단절에 의해 쉽게 깨어지지 않고, 경로상의 인접한 그룹 간에 연결이 완전히 끊어지지 않는한 유효하다. 시뮬레이션을 통해 높은 이동성과 높은 트래픽 상황에서도 그룹 라우팅 프로토콜이 다른 주요 소스 라우팅 프로토콜들보다 안정성이 뛰어나다는 것을 입증하였다. It is very hard, but important to sustain path stability for a reliable communication in mobile ad hoc networks. We propose a novel source routing protocol that establishes a group path with virtual multiple paths to enable a robust communication. The entire mobile nodes form a disjoint set of clusters: Each has its clusterhead as a cluster leader and a unique cluster label to identify itself from other clusters. A group path is a sequence of cluster labels instead of nodes and the nodes with the same label collaborate to deliver packets to a node with next label on the group path. We prove by resorting to simulation that our proposed protocol outperforms the existing key routing protocols, even for a network with a high node mobility and a high traffic.

Purpose: Organophosphate (OP) compounds insecticides are the most commonly associated with serious human toxicity all over the world. The aim of this study was to identify sociocultural factors that contribute to high incidence of pure OP poisoning and prevent OP poisoning in order to reduce the factors responsible for deaths in South Korea. Methods: This is the 38 multi-centers survey and prospective study of pure OP poisoning by structural reporting system and hospital records from August 2005 to July 2006. 238 patients with acute pure OP poisoning were enrolled. We collected patient information regarding poisoning, clinical, and demographic features. Results: The mean age was $55.32{\pm}17.3$ years old. The most frequent site of exposure was their own residence(85.7%). Frequent compounds involving pure OP poisoning were dichlorvos(22.7%), methidathion(8.4%), and phosphamidon(6.7%). Intentional poisoning was 77.9%. The most frequently route of exposure was ingestion(94.5%). The mean arrival time to hospital after poisoning was 12.7 hours and mean hospitalization duration was 12.9 days. 2-PAM was administered to 101 patients in mean doses of 6.3 g/day intravenously. Atropine was administered to 81 patients in mean doses of 74.6 mg/day (maximal 910 mg/day). The presence of lower level of GCS score, respiratory complications, hypotension, acute renal failure, and serious dysrhythmia was associated with serious and fatal poisoning. Overall final mortality in pure OP poisoning was 9.7%(23/238). Conclusion: This study highlights the problem of pure OP poisoning in South Korea as a basic national survey. Futhermore this might help the establishment of strict policies availability of OP and the statistics of OP poison exposure in South Korea.

Purpose: To assess the epidemiology and the clinical features of Glufosinate herbicide in Korea. Methods: Data was prospectively collected during 1 year since August 2005 from 38 hospital in Korea. We analyzed the epidemiologic characters and clinical manifestations of Glufosinate poisoning. In addition, the characteristics of patients with severe central nervous system toxicity were separately analyzed to find poor prognosis relating factors. Results: During study periods, there were 715 persons of poisoning of herbicides and insecticides. 6.3% (45 persons) of the agricultural chemicals poisoning had Glufosinate poisoning. There were 36 cases of suicide attempts and 7 cases of accidental exposure, The major of poisoning route was oral ingestion (44 cases). 28.9 % of the study patients had not toxic symptoms. The most common symptoms were gastrointestinal symptoms relating surfactant irritation. 67.7% of central nervous symptoms occurred lately. 10 persons showed severe central nervous system toxicity. 4 persons of them showed poor outcomes (1 death, 3 hopeless discharged). Complications of respiratory failure and renal failure related with poor outcome. Conclusion: Majority of patients ingested Glufosinate for suicide attempt. 22.2% of patients with Glufosinate poisoning showed delayed serious central nervous system toxicity. Early supportive care of altered mentality may prevent late respiratory complications and improve the outcomes.

Purpose: Dichlorvos has been in widespread use as an organophosphate (OP) insecticide compound. The purpose of this study was to access the epidemiology and clinical features of dichlorvos in Korea. Methods: This was a 38 multi-center prospective study of dichlorvos poisoning using surveys, a structural reporting system and review of hospital records from August 2005 to July 2006. A total of 54 patients with acute dichlorvos poisoning on a national basis were enrolled. We analyzed the epidemiologic characteristics and clinical manifestations of dichlorvos poisoning. In addition, the clinical features of dichlorvos poisoning were compared with others OP compounds. Results: During the study period, compounds involving pure OP poisoning were dichlorvos (22.7%), methidathion (8.4%), and phosphamidon (6.7%). In acute dichlorvos poisoning, all ingestion routes were oral. Intentional poisoning involved 74.1% of cases. The common initial complaints involved gastrointestinal (64.8%), systemic (61.1%), central or peripheral nervous system (53.7%), and respiratory symptoms (50.0%). The median arrival time to hospital after dichlorvos poisoning was 2.6 hours and mean hospitalization duration was 7.1 days. 2-PAM was administered in 35 patients in mean doses of 6.3 g/day intravenously. Atropine was administered in 30 patients with a mean dose of 62.8 mg/day (maximal 240 mg/day). Overall mortality rate for dichlorvos poisonings were 14.8% (8/54). Immediate causes for death included sudden cardiac arrest or ventricular dysrhythmias (50%), multi-organ failure (25%), acute renal failure (12.5%), and unknown causes (12.5%). Conclusion: When compared to previous reports, dichlorvos poisoning displayed relatively moderate severity. The presence of a lower GCS score, altered mental status, serious dysrhythmias, systemic shock, acute renal failure, and respiratory complications upon presentation were associated with a more serious and fatal poisoning.
