고주파 흡수제(Accusorb MRI)를 이용한 자기공명영상 검사 중 화재가 발생했다. 다행히 환자는 화상을 입지는 않았 지만 스트랩과 4채널 코일의 케이블, Accusorb MRI가 녹아서 탄 흔적이 발견되었다. 자기공명영상 검사에 사용되 는 도구의 안전 지침을 준수해야 하지만 이를 지키지 않으면 화상, 열상, 장비 손상의 위험이 있다. 사고를 방지하기 위해서는 철저한 사전 점검을 해야 하고 모든 기기, 물품들이 자기공명영상 검사 시 사용 가능한 제품인지 확인하고 사용법을 정확하게 숙지하여야 한다.

This paper attempted to analyze the correlation between the risk image of the evacuees in the tunnel and the variables that affect the evacuation behavior due to the closed feeling. As to whether there is a difference in the level of recognizing the tunnel risk image according to the distribution of jobs, the null hypothesis was rejected at the significance probability of 0.002, so it can be said that the level of recognition of the tunnel risk image varies depending on the job group. In the distribution difference between gender and tunnel risk image recognition level, the significance probability was 0.012, indicating that the null hypothesis was rejected, indicating that the tunnel risk recognition distribution according to gender was different. As a result of analyzing the distribution difference between the tunnel's closed feeling and the tunnel risk perception level, the significance probability was 0.001, and the null hypothesis was rejected, indicating that there was a difference in the tunnel risk image level.

본 연구에서는 LNG 공급계통시스템의 재기화 공정에서 배관 손상으로 인한 누출사고 발생시 LNG 성분 및 누출공의 크기에 따른 연소특성에 대한 피해범위를 산출하고, 피해영향을 해석하였다. LNG 성분에 따른 연소특성을 확인하기 위하여 7곳의 LNG 산지별 위험도를 확인한 결과 산지별 큰 차이를 보이지 않았으나, LNG 구성성분 중 메탄의 함유량이 많을수록 플래시화재 발생범위 및 증기운 폭발에 의한 과압이 발생하는 위험범위 그리고 제트화재 발생에 의한 열 복사량 피해영향이 다른 산지에 비해 비교적 낮음을 알 수 있었다. 또한 배관 누출공의 크기에 따라 누설, 파공, 파괴 3단계에 나누어 위험 범위 및 폭발에 미치는 영향에 대한 연구를 수행하였으며, 플래시화재로 인한 피해영향범위를 계산하고, 이에 따라 LNG 누출시 화재가능 위험범위를 확인했으며, 과압의 영향 및 복사열로 부터의 피해범위를 예측할 수 있었다. 이를 통해 LNG 조성 및 배관 누출공의 크기가 화재 및 폭발에 미치는 영향을 예측할 수 있었다.

컨테이너를 이용한 위험물의 해상운송이 증가함에 따라 적재불량으로 인한 위험물의 누설 등으로 선박에서 화재사고가 발 생하고 있다. 한편, IMO(MSC.93)에서는 2016년 1월 1일 이후 건조되는 개방갑판상에 컨테이너를 5단 이상 적재하도록 된 모든 선박은 물분무창(Water Mist Lance, WML)이라는 소화장치를 선박에 의무적으로 비치하도록 규정하였다. 본 연구에서는 LS-DYNA를 이용하여 최적의 첨단곡률반경을 가지는 WML을 설계하기 위한 수치해석을 수행하였다. 첨단부분의 길이가 10 mm, 15 mm, 20 mm인 3가지 모델에 대한 해석결과 길이가 15 mm인 경우만 컨테이너 벽면을 관통하고, WML의 첨단부분에 손상을 일으키지 않는 결과를 나타내었다. 향후, 본 연구결과를 바탕으로 테스트용 WML를 제작하여 성능실험을 할 계획이며, 문제점은 지속적으로 개선해 나갈 것이다.

In January, 2005, the "Railroad Safety Act" was presented, preparing the systematic equipment that allows several railroad operators to consider the railroad safety issue, and each of the railroad operative institutions accepted such situation that the construction of the emergent system of coping, resulting in the construction of the emergent system of coping with the railroad fire accident through the relevant study to improve the railroad security efficiency against fire. This study tried to present the on developing the emergent educational program for coping with the KTX fire accident, which is distributed to the spot, to the railroad emergency staff for improving the railroad security efficiency against fire through the education of systematic and efficient emergent countermeasure procedures against fire accidents the fire accident in KTX.

The effect of parameters on the consequence of the flash fire accident by the release of heavy gas(in this study, xylene vapor) was analyzed. Simulation results showed that the distance with the lower flammable limit(XLFL) was increased with the increase of the release hole diameter. For the case of the elevated release, XLFL was increased with the increase of the wind speed and the release height, but XLFL was not affected by the wind speed for the release on the ground level. Therefore, the accident in the elevated release was more dangerous than the release on the ground level. In this condition, the release height had more effect on XLFL at the night time than the daytime and in the urban area than the rural area.

Since 1990's, many enterprises have implemented ERP System. Especially, they want to become an advanced company use ERP implementation. Already, ERP system come to high level which is stabilized and support independent business process of many industry sectors. Although most companies had previous good plans, but those are not satisfied. Because of failed to change management and had many problem about Project team operation. Therefore, important success factors for ERP project are change management and organization activation for Project team. The purpose of this study is suggest to improve method about team activation through analysis the Project team member's individual personality as a factor that makes the success of Project team. This paper studied success factors of project team and plan for organization activation. The results of this study can be used for a successful implementation of the ERP system as make of Project team consider of individual personality and administer a Project team.
