  • The purpose of this study is to ascertain the demands for developing marine science technology to reduce fatalities caused by marine accidents. For this purpose, we analyzed the contents of about 77,000 news articles posted for a month after the tragedy of the Sewol (April 16~May 15) to identify keywords and then we used the Social Network Analysis (SNA) for each keyword. The findings of the analysis show that there are five networks and that each one reveals different aspects about technology development to prepare for marine accidents. Based on these findings, we categorized three kinds of demands for technology development from the perspective of marine science technology: provision of the information about the marine environment, development of equipment and technology to overcome extreme environments, and the establishment of a field support system.

  • Hydropower is now changing its role from the energy generator into the most powerful and reliable tool for stabilizing the electrical network, especially under the increase of intermittent power sources like wind-power and solar-power. Although the hydropower plants are the most robust generating facilities, they are not immune from unexpected severe incidents having long downtime, considerable restoration cost and sometimes fatalities. The present paper provides some study results about severe incidents in the conventional hydropower plants, mainly about the flood, fire and electro-mechanical troubles, except for the incidents of civil facilities. It also provides some possible scenarios which may lead some measures how to avoid such incidents. Finally, it provides some comprehensible recommendations to avoid severe incidents based on experiences.

  • Accidental or suicidal fatalities of paraquat(Gramoxon) poisong are occasionally seen in the emergency room or intensive care unit in this country. In most cases, respiratory symptoms and eventual death by respiratory distress occur within several days. The most striking pathologic change is fibrosis of the lung due to widespread proliferation of fibroblastic cell. We experience a 21-year-old woman with huge bulla on left lung and diffuse fibrosis in other site, who ingested paraquat 10 months ago. After thoracoscopic removal of bulla, the patient survive without progression of pulmonary complication till now.

  • 대피 및 인명피해 시뮬레이션 기술은 성능위주 설계의 핵심 기술 중 하나이다. 기존 해외에서 개발된 프로그램들은 단순한 인명피해 계산 방식과 비주얼의 조악으로 한계성을 나타내고 있다. 본 연구에서 개발된 대피 및 인명피해 평가 프로그램은 기존의 프로그램의 한계점을 극복함과 동시에 다음의 관련 기술을 향상시키고 실제 사례에 적용하여 현재 사용되고 있는 상용 대피 프로그램과 비교/검증하였다. 첫째, 피난계단 뿐만 아니라 엘리베이터를 이용하여 대피할 수 있는 알고리즘을 적용하였다. 둘째, 미국 표준연구소(NIST)의 화재해석 프로그램 (FDS, Fire Dynamics Simulator)과 연계(Coupled)를 통해 화재에 의한 인명피해 발생여부 판단이 가능한 프로그램이다. 마지막으로 그래픽 전용 모듈을 적용하여 현실에 가까운 3차원 가상현실을 구현하였다.

  • Malaria is a major cause of death in tropical and sub-tropical countries, killing each year over 1 million people globally; 90% of fatalities occur in African children. Although effective ways to manage malaria now exist, the number of malaria cases is still increasing, due to several factors. In this emergency situation, prompt and effective diagnostic methods are essential for the management and control of malaria. Traditional methods for diagnosing malaria remain problematic; therefore, new technologies have been developed and introduced to overcome the limitations. This review details the currently available diagnostic methods for malaria.

  • After a thorough investigation of aviation accidents involving Korean national carriers both inside and outside of Korea and also after reviewing catastrophic events involving foreign carriers in Korea, we found numerous accidents that caused fatalities and serious personal injuries. Although the aircrafts involved were found to have no specific defects, many of the accidents were caused by the pilot's misjudgement according to previous studies. Our research is to find an new procedure to help the prevention of similar accidents by focusing particularly on CFIT accidents during the procedural operations of Non Precision Approach, Circling Approach and Visual Approach. Therefore, we emphasize the significance of this research on the development of the new checklist that will help achieve a safe and effective procedural operation for non precision approaches.

  • This study shows risk-based evaluation results of casualty accidents for passengers, railway staffs and MOP(Member of public) on the national railway in South Korea. To evaluate risk of these accidents, the hazardous events and the hazardous factors were identified by the review of the accident history and engineering interpretation of the accident behavior. A probability evaluation model for each hazardous event which was based on the accident appearance scenario was developed by using the Fault Tree Analysis (FTA) technique. The probability for each hazardous event was evaluated from the historical data and structured expert judgment. In addition, the severity assessment model utilized by the Event Tree Analysis (ETA) technique was composed of the accident progress scenarios. And the severity for the hazardous events was estimated using fatalities and weighted injuries. The risk assessment model developed can be effectively utilized in defining the risk reduction measures in connection with the option analysis.

  • Regarding the characteristics of fatal electric shock accident during the past 10 years, fatalities occurred more frequently in July & August, and AM 10-12 PM & 14-16. Also, the electric shock accident is occurred more frequently in the age group from 30 to 40. Especially, the fatal electric shock accident in construction industry covered more than half of total industry. Therefore, it is strongly requested for the protection technology of an electric shock from the low voltage electric path, grounding method and workers. The aim of this study is to propose the policy about the equipment performance standards and/or worker's safety standards to revise the standards for preventing electric shock accidents on safety workings.

  • Experimental results obtained from research using only one sex are sometimes extrapolated to both sexes without thorough justification. However, this might cause enormous economic loss and unintended fatalities. Between years 1997 and 2000, the US Food and Drug Administration suspended ten prescription drugs producing severe adverse effects on the market. Eight of the ten drugs caused greater health risks in women. Serious male biases in basic, preclinical, and clinical research were the main reason for the problem. This mini-review will describe why and how funding organizations such as the European Commission, the Canadian Institutes of Health Research, and the US National Institutes of Health have tried to influence researchers to integrate sex/gender not only in clinical research, but also in basic and preclinical research. Editorial policies of prominent journals for sex-specific reporting will also be introduced, and some considerations in integrating sex as a biological variable will be pointed out. To produce precise and reproducible results applicable for both men and women, sex should be considered as an important biological variable from basic and preclinical research.
