The purpose of this study was to suggest direction of government policy to support residential environment. For the purpose, the policies of central and local governments and materials issued for the introduction of policies to persons with plans to return to farm were collected and analyzed in order to explore focal policies. This study utilized content analysis method. In the first step, information on support policies for the return farm planners were collected from Internet. In this step, the residential environment support policies were categorized into two types; village support type and household support type. The village support was classified into central government support and local government support. Types and their characteristics of the policies were analyzed. In the second step, the materials disseminated at the ‘Return-Farm Festival, 2012’, held in Seoul between May 4 and 6, 2012, were analyzed. In the festival, 9 provincial governments and 39 local governments participated. Findings are as follows: (1) Governments were more active to introduce their policy online than offline such as participation in the festival; (2) The materials disseminated at the festival had more information on the household support policies than the village support policies. Local governments, however, emphasized their village support policies. The household support policies were mainly focused on repair support and purchase loan.

본 논문은 IEC형 불꽃점화 시험장치를 이용하여 저압 유도회로의 최소 점화한계를 프로판-공기 5.25 Vol.%의 혼합 가스에 대하여 실험적으로 구하였으며, 또한 유도회로의 인덕턴스 L에 안전소자로서 저항을 병렬접속하였을 경우 프로판-공기 5.25 Vol.%의 혼합 가스에 대한 점화한계 개선효과를 관찰하였다. 그 결과, 최소 점화한계는 전류의 크기에 따라 좌우되었다 또한, 전원으로부터 공급되는 에너지는 인덕턴스에 우선 축적되고. 그 초과분의 에너지가 폭발성 가스의 점화원으로 작용하였다. 점화한계 개선효과는 인덕턴스가 300 mH일 때, 최고 330%의 개선효과가 나타났으며 인덕턴스가 클수록 점화한계 개선효과가 크게 나타났다. 또한 병렬로 접속한 저항의 크기가 적을수록 점화한계 개선 효과가 크다. 본 연구결과는 본질안전 방폭형 전기기기의 연구개발을 위한 기본자료로 활용할 수 있을 뿐만 아니라 이들 기기의 방폭성능에 대한 시험자료로도 활용이 가능할 것으로 사료된다. This paper describes the minimum ignition limits for propane-air 5.25 Vol.% mixture gases in low voltage inductive circiuts. The improved effects on the ignition limit are studied by parallel safety components(resistors) for propane-air 5.25 Vol.% mixture gas in low voltage inductive circuits. The experimental devices used in this test are the IEC type spark ignition test apparatus. The minimum ignition limits are controlled by the values of current in inductive circuit. Energy supplied from elect source is first accumulated at the inductance, it's extra energy is working as ignition source of the explosive gas. The improved effects on the ignition limit are respectively obtained as the maximum rising rate of 330% by composing parallel circuits between inductance and resistor as compared with disconnecting inductance with the safety components. The more values of inductance increase the higher improved effects of ignition limit rise. The less values of resistor the higher improved effects of ignition limit rise. It is considered that the result can be used for not only data for researches and development of intrinsically safe explosion-proof machines which are applied equipment and detectors used in dangerous areas but also for datum for its equipment tests.

이승한,최옥경,정구영 大韓應急醫學會 1996 대한응급의학회지 Vol.7 No.1

The Emergency Medical Technitian(EMT) is the main personnel of Emergency Medical Service Systems, requiring a whole set of special rescue skills and the knowledges for emergent patients in prehospital area. The most important aspects of the EMT system is the medical direction, which is education, protocol, and quality assurance especially in implementing phase. The EMT system just has been started in Korea with legislative effort of Emergency Medical Act since 1994. There has been no data about the frequencies of prehospital emergency care and it`s medical evaluation. Therefore, we investigated the volume of the prehospital emergency care performed by 119 rescue personnel, and assessed the accuracy of cardiopulmonary resuscitation(CPR) skills. We also analyzed which personal factors influence the accuracy of CPR skills by using the multiple regression test in SAS program. One hundred sixty four(64.5%) of the 259 rescuer graduated highschool, and 66.4% had less than 4 years career as a rescuer. Sixty one percentage has less than four times of CPR training. The interval from the last CPR training was less than 6 months in 59.1%, and less then 1 year in 71.4%. While over 75% of 119 rescuers had the experiences of primary emergency cares, about 50% had of CPR and of vital sign check. The accuracy of chest compression were 48.3%, 50.2%, and 52.2% in the rate, depth, and the site, but the accuracy of ventilation, and the ratio of inspiration and expiration. The accuracy of CPR was influenced only by times of CPR training(p=0.0083), not by the education level, the professional career, nor interval after the last training. From the above results, we could have conclusion that EMT training program should be focused to the initial patient assessment, and CPR training should be shared more time in ventilation than in chest compression. Also we could reach to a conclusion that it is important to increase the times of CPR training for improving the accuracy of CPR and that the proper interval of the training might be less than 3 months in early phase.

Background: The sigmoid septum described an anatomical variation in the contour of the left ventricular outlet. It is related to degenerative change with aging. We observed clinical significance of sigmoid septum in Korean. Methods: Echocardiographic examination was performed in 434 patients. Sigmoid septum is defined as discrete bulging of the proximal interventricular septum with that thickness is greater than 1.3cm or the thickness is grater 1.5 times than adjacent mid interventricular septum in apical 3 chamber view. Result: The incidence of patient with sigmoid septum(septum patient) is 24.8% (male 8.4%, female 16.3%) . The incidence increases with age and is more common in women. The patients with sigmoid septum were compared with targeted groups, there was no significant difference in blood pressure between them, but in height and weight, the former were lower. (p<001, p<03). In the patients with sigmoid septum, weight and the surface area of a body have an opposite correlation with increase of age (p<03, r=-0.34) (p<04, r=-0.31) , but no decrease of height was found according to age increase (p=0.47, r=-0.11) The main reason patients with sigmoid septum ask echocardiolography and its clinical symptoms were abnormal results of previous electrocardiography and/or usual chest pain. Compared with control group, interventricular septal thickness is larger in septum patients (p<001). The thickness of interventricular septum located in subaortic left ventricular outflow tract is 1.6±0.3cm. There is another web like structure that continued from interventricualr septum to anterior free wall of left ventricle and the width is 1.6±0.4cm. A sign of insignificant obstruction due to left ventricular outflow was observed from three sigmoid septum patients. Conculusion: Septum patient is largely found in older age group and the body weight and body surface area are lower than control group. The body weight and body surface area are opposite correlation with age. So sigmoid septum is considered as structural change by weight reduction with aging. It is assumed that septum patients are related with asymptomatic ischemia because they have more abnormal ECG finding such as T wave inversion on precordial leads or standard leads, nonspecific ST-T change, LBBB etc. Sigmoid septum is not only proximal interventricular septal bludging but also another web like structure continuing to anterior wall of left ventricle.

Endotracheal intubation is one of the important procedures in ED and various fields. Endobronchial intubation can lead to hypoxemia secondary to tension pneumothorax of intubated side and atelectasis of contralateral side. The placement of tube beyond the vocal cords may results in inadvertent extubation, larygeal spasm and aspiration pneumonia. The conformation methods of endotracheal intubation are auscultation of the chest, observation of a vapor trail, oximetry and capnography, and radiologic evaluation. Owen and associates recommended that oral intubation tubes at the upper incisor teeth at the 23cm in men and the 21cm in women of average adult size would have led to proper placement. We studied that whether the proper depth of endotracheal tube in American is appropriate to Korean. We studied adult patients admitted to ED (of both hospitals during March in 1995. Endotracheal tubes in men were positioned at the 23cm and women had positioned at the 21cm at the upper incisor teeth. The distance of the tip of the endotracheal tube to the tracheal carina on the postintubation chest X-ray then determined. Correct placement of intubation was defined with the tip of the tube≥3cm above the carina and below the level of the larynx. Fifty adult patients were enrolled in the study ; 29 men (58%) and 31 women (42%). Mean height and weight were 170±5.2cm, 68±9kg in men and 158±6.5cm, 56±10kg in women. Reasons for intubation were ; respiratory failure(38%), trauma(16%), increased intracramial pressare(16%), drug intoxication(12%), shock(8%), cardiac arrest(7%)and others(3%). The mean distance from the tip to carina on chest X-ray was 4.13±1.5cm in men and 3.45±2.1cm in women. Proper position was 27/29(93%) in men, 14/21(67%) in women or 41/50(82%). this means the placement of endotracheal tube of our patients was positioned deeper than prion study group(97.6%).(p<.05) We recommend that the 22cm tube mark for men and 20cm tube mard for women at upper incisor teeth would have led to proper placement in Korean adult patient.

Objective : This study was conducted to develop and to validate the Korean version of Delirium Rating Scale-Revised-98(K-DRS-98), which is a scale for diagnosing delirium and evaluating its severity. Method : After developing the K-DRS-98, 102 patients were rated by it among 4 diagnostic groups, such as delirium (N=25), dementia (N=27), schizophrenia (N=25) and others (N=25). To test for reliability, K-DRS-98 was independently administered by two psychiatrist. To test for validity, Korean version of Mini-Mental State Examination (MMSE-K) and Clinical Global Impression (CGI) were administered simultaneously. Statistical analysis was done with SPSS window version 12 package and statistical significance was p<0.05. Result : Intemal consistencies (Cronbach α) of two raters were 0.867 and 0.858, respectively. Inter-rater reliability (κ) was 0.893 for severity items of K-DRS-98 and κ value of diagnosis items was 0.969. In Delirium group, Pearson correlation Coefficients (r) of K-DRS-98 were -0.682 for MMSE-K and 0.667 for CGI. In comparison Delirium group with Others, ANOVA post hoc multiple comparison LSD was statistically significant (p<0.001). The cutoff score to diagnosis of delirium can be recommended 16 for seventy items and 21.5 for total score, respectively. Conclusion : The K-DRS-98 was showed good reliability and validity for the assessment of delirium. The K-DRS-98 is an easy and useful tool for diagnosing delirium and assessing its severity.
