This study evaluated the completeness of patient care report (PCR). A retrospective quality analysis was conducted using raw data of 122,140 EMS activity reports prepared by paramedics in Gyeonggi-do from April 1 to May 31, 2021. In all, 67,830 cases of normal transfers were statistically analyzed using IBM SPSS Statistics version 22, and statistical significance was set at p<0.5. The 119EMT_2 certificate was omitted in 50,037 (73.8%) cases, followed by time-related items in 1,227 (1.8%) cases. In the primary assessment of vital signs, systolic blood pressure was omitted and erroneous in 1,218 (1.9%) and 1,129 (1.8%) cases, respectively. In the secondary assessment, the completeness of all vital sign items was approximately 70%. Advanced emergency care and online medical control (OLMC) reporting showed discrepancies in all items. As the severity of the patient's condition increased, the errors in the Patient care report (PCR) also increased, at a significant level (p= .00). Paramedics must be aware of the importance of completing the activity report.

본 논문에서는 실제 규모 데이터센터의 3D 모델링을 기반으로 대상 공간별 화재 시나리오를 선정하여 화재 및 피난 시뮬레이션을 수행하였다. FDS와 Pathfinder는 full coupling 방식을 사용할 수 없는 한계가 있으며 semi coupling의 경우 가시화에는 도움이 되나 결과에 영향을 주지 않는다. 따라서 재실자의 피난 상황 시 경로에 대한 안전성과 화재 위험 노출 정도를 시각적으로 분석하는 것이 가능한 semi coupling과 시뮬레이션 결과 데이터 분석을 병행하여 수행하였다. 전산실의 경우 서버의 기능상실 한계 온도가 32도이기 때문에 서버 기능 정지 상황에 도달하는 시간을 중점적으로 분석하였다. 전산실은 업무 및 고객 서비스와 관련된 모든 데이터들을 저장하기 위해 항시 기동 되어야 하는데 전산실 내 화재가 발생할 경우 1~2분 이내 서버 기능이 정지되는 상황이 발생하였다. 따라서, 서버가 안전하게 계속 동작하기 위해서는 전력 계측 및 제어 케이블 열화, 서버 장치의 건전성이 유지되어야 하며 초기 화재를 빠르게 감지하여 진압하여야 한다. 피난 시뮬레이션의 경우 가시도를 상실하게 되는 시간이 약 195초(5m 미만) 인근으로 인원이 해당 층을 완전히 벗어나는 데 걸리는 시간이 약 125.6초였던 것을 보면 대피하기에 충분한 허용 피난시간(ASET)을 확보하고 있음을 알 수 있었다.

Purpose - In the insurance distribution channel, the salespeople plays a role of representing the company, and recognizes the needs of the customers and plays a role in responding to them. Therefore, their turnover can have a great influence on the company performance. The purpose of this study is to investigate the structural relationship between salespeople's personal - environmental fit and organizational commitment and turnover intention. Research design, data, and methodology - Data collection was conducted a self-filling questionnaire for salespeople for about one month from July 24, 2017 to August 30, 2017. The subjects of the questionnaire were the insurance salespeople who work in the sales line such as K life, S fire. A total of 450 copies were distributed and 432 copies of the questionnaire were used for final analysis. The analysis program used SPSS 22.0 and AMOS 22.0 programs. Analysis method was Frequency Analysis, Reliability & Confirmatory Factor Analysis, Correlation Analysis and Structural Equation Model(SEM). Results - As a result of Hypothesis 1, Person-Supervisor Fit had significant influence only on Continuance Commitment. Person-Job Fit did not have a significant effect on Organizational Commitment. Person-Coworker Fit had a significant effect on Continuance Commitment and Affective Commitment. Person-Organization Fit had a significant impact on Affective Commitment. Therefore, only , , , , were adopted. As a result of Hypothesis 2, Continuance Commitment had a significant effect on turnover intention. Therefore, only was adopted. Conclusions - This study suggests that it is necessary to manage the human resources in the sales field through studies related to salespeople's extension of the research scope and salespeople's turnover intention. Based on the results of this study, the conclusion suggests some implications for the efficient human resources management of insurance companies in sales channels. It is expected that it will be helpful for the salespeople to find out what kind of Person-Environment Fit affects the organizational commitment and how to manage the organizational commitment among the three dimensions of organizational commitment to reduce turnover intention.

Purpose : The purpose of this study was to reveal some factors of ROSC & survival for cardiac arrests from sport & leisure activities(CASLs). Methods : A retrospective study of the 1,341 out of hospital cardiac arrests(OHCAs) treated by EMS in Gyeonggi Provincial Fire and Disaster Headquarters from January to December in 2008 was conducted. The primary end-point was admission to emergency room. To clarify the factors through comparison of CASLs(n=58) with ROSCs & survivals(n=58), Answer Tree analysis for data mining with the CHAID algorithm was performed and alpha was set at .05. Mean, median, and percentile of time intervals, distances, and age on the 58 CASLs, 75 ROSCs, and 27 survivals(patients admitted to emergency room) were analysed. Results : Fourteen CASLs(24.1%), 41 ROSCs(54.7%), 16 survivals(59.3%) were treated with CPR within 5 min., and only 2 CASLs(3.4%), 11 ROSCs(14.7%), 10 survivals(37.0%) were treated with defilbrillation within 10 min. from arrest. If time recording from arrest to defilbrillation, the patients were classified 81.0%($X^2=9.83$, p=.005) into ROSCs & survivals. And the patients with no history, 100.0%($X^2=5.44$, p=.020). The other patients with no intention, 87.5%($X^2=7.00$, p=.024). Whereas the other patients with intention, treated with CPR after 4 min. from arrest were classified 67.2%($X^2=3.99$, p=.046) into CASLs. Conclusion : CPR within 4 minutes was the most important factor that discriminates between CASLs and ROSCs & survivals to record cardiac arrests-defilbrillation time. CPR within 4 min. from arrest, no history, and no intention were factors for improved ROSC & survival.

Release and fire/explosion tests of flammable gas are extremely dangerous. Furthermore, it is difficult to select the site where the experiment can be performed. In these reasons, gas flow analysis(CFD) has been used as much as possible. However, with the opening of the Energy Safety Empirical Research Center in Yeongwol-gun, Gangwon-do in October 2016, it was possible to conduct releases and detection tests of small scale combustible gas as well as large scale / high pressure / ultra low temperature experiments. In this study, LPG leaked after the calibration and placement of the sensor, the sensor detected LPG and the data were visualized as a contour map. And the differences between the actual release(28s, max 3.7[m]) and the analysis were analyzed compared to the FLACS analyzed under the same conditions.

The kinetic analysis of energetic materials using Differential Scanning Calorimetry (DSC) is proposed. Friedman Isoconversional method is applied to DSC experiment data and AKTS software is used for analysis. The proposed kinetic scheme has considerable advantage over the standard method based on One-Dimenaionl Time to Explosion (ODTX). Reaction rate and product mass fraction simulation are conducted to validate extracted kinetic scheme. Also a slow cook-off simulation is implemented on $B/KNO_3$ for validating the applicability of the extracted kinetics scheme to a practical thermal experiment.

In terms of electrical safety, environmental impact assessment and revision of domestic regulation are needed for the electric facilities. In this paper, risk of electric facilities is assessed by the spot measures and analysis in dust generation area. Adhesion dust in a surface of insulated materials cause electrical accidents. In a mechanism of these accidents, when the dust lie on electric facilities, a leakage current is flowed and the surface of insulated material is carbonized. Hereafter, electrical fire is generated due to Joule's heat. As the results, dusts are found in protection devices or panel board and sampled dusts vary in sampled amounts and conductivity severally. For the most part, sodium is detected but zinc and calcium are detected in case of reclaimed rubber factory by the ICP-AES(Inductively Coupled Plasma-Atomic Emission Spectroscopy). In a sewerage, the ingredients such as sodium, magnesium, iron, calcium, aluminium, etc are detected uniformly. So that, results of the spot measures and analysis of dusts are become the important data for the assessment of electrical hazard in dust generation area.
