Due to corrosion defects on the surface of the oil pipe, the sealing performance of the annular blowout preventer (BOP) decreases, and the leakage of toxic and harmful gases such as H₂S and SO₂ will threaten the safety of operators on the well. Therefore, this paper establishes the FE model for evaluating the sealing performance of BOP-oil pipe corrosion defects, which is based on the rubber large deformation theory and rubber core sealing mechanism, and designs the experiment of BOP sealing performance to verify the accuracy of the FE model. The sealing performance of BOP sealing oil pipe with corrosion defects is studied. The research results show that the sealing performance of BOP is more sensitive to the axial size of corrosion defects. With the increase of oil pipe outer diameter, the critical size of defects increases continuously. The sensitivity of radial and depth dimensions is low, When for 88.9 mm outer diameter oil pipe, the axial critical size of corrosion defect is 20 mm, the radial critical size is 16 mm and the critical depth is 2 mm. Fit the formula between the outer diameter of oil pipe and the piston increment. According to the formula, the operator can calculate the piston stroke increment required by the BOP to complete the sealing when the oil pipe is corroded.

Purpose : The study examined the knowledge and health education about first aid of college students. Methods : The survey had done from October to December, 2022. Total subjects in this study were 205. The collected data were analyzed by SPSS 24.0 program. Results : Regarding the difference in first aid knowledge according to the first aid education characteristics of the subjects, significant differences were observed in experience of first aid training (t=6.54, p(.01), necessity of first aid training (t=3.60, p(.01), and number of first aid training sessions (F=5.40, p(.01). In the case of first aid education experience, first aid education was necessary, and the knowledge score was the highest tn the three or more training sessions. As for the contents of first aid education, action tips in case of emergency, fracture, dislocation, sprain was the highest, and rescue and transport was the lowest. Conclusion : Continuous and systematic first aid education for college students is needed, and it is absolutely necessary to develop an advanced treatment education program to revitalize it.

Background: Underground mines have several hazards that could lead to serious consequences if they come into effect. Acquiring, evaluating, and using the real-time data from the atmospheric monitoring system and miner's positional information is crucial in deciding the best course of action. Methods: A graphical user interface-based software is developed that uses an AutoCAD-based mine map, real-time atmospheric monitoring system, and miners' positional information to guide on the shortest route to mine exit and other locations within the mine, including the refuge chamber. Several algorithms are implemented to enhance the visualization of the program and guide the miners through the shortest routes. The information relayed by the sensors and communicated by other personnel are collected, evaluated, and used by the program in proposing the best course of action. Results: The program was evaluated using two case studies involving rescue relating to elevated carbon monoxide levels and increased temperature simulating fire scenarios. The program proposed the shortest path from the miner's current location to the exit of the mine, nearest refuge chamber, and the phone location. The real-time sensor information relayed by all the sensors was collected in a comma-separated value file. Conclusion: This program presents an important tool that aggregates information relayed by sensors to propose the best rescue strategy. The visualization capability of the program allows the operator to observe all the information on a screen and monitor the rescue in real time. This program permits the incorporation of additional sensors and algorithms to further customize the tool.

본 연구는 부력가방의 익사사고 저감성능 분석에 관한 연구로서, 시민들은 레저 활동 및 물놀이 활동 시 부주의로 인하여 익사사고가 발생할 경우 119구조대나 타인의 구조활동만으로는 사고자 생존율이 저조하다고 할 수 있다. 이에 따라 수상 전문가들은 부력제품을 활용하여 익사사고를 줄이고, 시민은 일상용 휴대가방에 안전관리 기능을 추가한 부력가방을 평상시에 차량안이나 개인이 직접 휴대함으로써 본인의 생명과 위급한 상황에 봉착한 타인을 신속하게 구조할 수 있는 구명용 도구로 활용할 수 있도록 하였다. 본 연구를 통하여 개발된 부력가방은 편리성 안전성 지속성의 3가지 방재특성을 지니고 있으며, 서류 물품 등을 보관하는 편리성, 성인 1명 기준인 90 kg 무게를 띄울 수 있는 부력재를 내피 분산방식으로 처리한 안전성, 그리고 방수원단 및 방수지퍼 사용으로 장시간 안전을 유지하는 지속성 등을 갖춘 제품이다. 성능분석 결과 부력가방이 다른 구조장비와 비교해도 현장 간접 구조장비로 사용하는데 아무런 문제점이 없다는 것을 알 수 있었으며 부력성능과 디자인적인 측면만 더 보완하면 국민의 귀중한 생명을 보호하는데 많은 기여를 할 수 있을 것이다.

Purpose : This study was attempted to check the correlation between job satisfaction and turnover intention and to provide the basic information to increase job satisfaction of fire fighters. Methods : A total of 369 questionnaires were distributed and 354 questionnaires were filled out and collected for analysis. Results : There was difference in turnover intention by general characteristics. According to position, group of Fire lieutenant or more is lower than that of Fire sergeant or less (F=3.61, p=.014). The group of rescue & emergency service and administration was significantly lower than other groups(F=4.84, p=.001). In pattern of duties, day service group was significantly lower than shift work group in .05 level(t=2.59, p=.022). Finally, in the correlation, the more job satisfaction increase, the more turnover intention decrease that represents inverse correlation between job satisfaction and turnover intention(r=-.523, p <.001). Namely, it represents the results that the higher job satisfaction is low turnover intention. Conclusion : More studies of fire officer in other cities are required to generalize the results. We have to develop program for job satisfaction for fire officer firstly, because program for job satisfaction used in this study was not developed for fire fighters.

Purpose: The purpose of the study is to check up the status of 119 emergency control centers usage. Therefore, the status of use of 119 emergency control centers and the incidence of pre-hospital cardiac arrest patients were investigated. Methods: The emergency activity daily reports and first aid diaries of 119 emergency control centers from January to December 2018 were reviewed. For more accurate status analysis, Among the first aid guidance received in the emergency rescue standard system, the cardiopulmonary resuscitation guide log was reviewed. Results: In 2018, the total usage of the 119 emergency control centers was 1,358,356 calls, hospital guidance werethe most commom (n=629,676, 46.4%), followed by first aid (n=428,027, 31.5%), disease consultation (n=170,238, 12.5%), medical oversight (n=111,188, 8.2%), and interhospital transfer (n=5,052, 0.4%). Regarding the user number per 1,000 persons, Jeju was the greatest at 48.0, whereas Changwon was the lowest at 13.0. A total number of dispatcher-assisted cardiopulmonary resuscitation was 12.181. The time from report to chest compression were 156.2±80.8 seconds for those with previous cardiopulmonary resuscitation training and 168.0±79.3 seconds for those without such training (p<.05). Conclusion: The ratio of first aid instructions, including dispatcher-assisted cardiopulmonary resuscitation, among total usage of the 119 emergency control centers increased. Therefore, additional efforts are required to improve the quality and expertise of information provided through the 119 emergency control centers.

간호사는 의료법 상 의료인으로서 의료기관에서 진료의 보조 등의 업무를 수행한다. 의료인인 간호사는 119 구조·구급에 관한 법률에 근거 구급대원으로서 병원 전 단계 응급의료체계에서 응급환자를 대상으로 응급의료를 제공한다. 병원 전 응급의료체계에서 업무를 수행하는 간호사의 업무범위는 의료법 상 포괄적으로 규정되어 있는 업무를 판례 등을 통해 구체화되어 왔다. 반대로 응급구조사의 업무범위는 응급의료법에 의해 구체적 행위를 열거하는 방식으로 규정되어 있다. 병원 전 단계 응급의료체계에서 응급의료종사자로서 업무를 수행하는 간호사의 업무범위는 대상 환자의 긴급성, 응급의료기관으로의 이송 중이라는 점, 통신 상의 의료지도라는 특수성을 고려하여 간호사의 업무범위를 의료기관 내에서와 달리 적용하여 해석되어야 한다. 따라서 상대적으로 병원 전단계에서 간호사가 응급구조사보다 넓은 업무범위가 인정되고 이것이 정책목표에도 부합된다.

Many reports have been published on complications related to middle cerebral artery (MCA) aneurysm surgical clipping procedures. We report an emergency intracranial in situ bypass surgery case which was performed as a rescue procedure after aneurysmal neck laceration during clipping of an MCA large aneurysm. In this case, we performed in situ M3-superficial temporal artery (STA) interposition graft-M3 bypass procedure. If a STA-MCA anastomosis is not available under MCA flow obstruction, we can consider an emergency in situ MCA-MCA bypass procedure with or without an STA interposition graft.
