  • Korea had the highest accident rate among OECD countries in 2018, with 8.4 per 100,000 population, ranking 4th among 35 countries. In addition, the accident rate of traffic with children and the elderly was also high. This study reviewed the relevant literature and analyzed the traffic-accident analysis system. Customized traffic safety facilities were developed. In addition, by measuring the visibility of the traffic safety facilities by installing a test bed, this study measured the forward driving frequency and vehicle driving speed while driving. As a result of applying the "pedestrian pedestrian model" collision test model, the possibility of serious injury after installing the facility was reduced greatly to 4.6%. In this study, the visibility of traffic safety facilities and the effect of reducing the traffic speed were verified through test beds. Recognizing traffic safety facilities will reduce traffic accidents.

  • It is expected that the vehicle safety systems using vehicle-to-vehicle communication can reduce the possibility of vehicle collision and prevent the chain crash by promptly delivering the status of neighboring vehicles. Many IEEE 802.11 DCF based Flooding schemes have been proposed, but they may generally expose the problems that the chances of a chain-collision reaction are sharply increased as the vehicle density has increased. Therefore, this paper proposes the chain-collision prevention scheme using a broadcasting-based adaptive report. The proposed method can adaptively allocate the preoccupancy right based on a quantitative priority order and then promptly deliver the warning messages in neighboring areas. Moreover, it is shown from simulation that the proposed scheme provides the performance gains over the existing Flooding based scheme.

  • The process and facilities of modern chemical plants are becoming increasingly complex, there is possibility of potential risk. Internal chemicals generate stress concentration when operated due to turbulence, laminar flow, pressure, temperature, friction, etc. It causes cumulative fatigue damage, which can damage or rupture chemical facilities and devices. The statistics of chemical accidents found that the highest rate of occurrence was in summer, and in the last five years statistics on chemical accidents, leakage incidents make up a decent percentage of accidents. Chemical leaks can cause serious human damage and economic damage, including explosions and environmental pollution. In this study, based on the leak accident of chemical plant, the risk analysis, and damage effects assessment were estimated using a 3D scanner and FLACS. As a result, if chemicals leak in summer, the risk is higher than in other seasons, the seasonal safety management measures, and countermeasure were estimated.

  • The purpose of this study was to identify to identify the relationship between knowledge of the SBAR(Situation-Background-Assessment-Recommendation) Attitudes towards SBAR and critical thinking disposition of nursing students. Subjects were 101 associate nursing students associate nursing students(3rd). The data were collected using self -report questionnaire from August 31 to October 26, 2018. Data were analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation using SPSS Win 23. The score for knowledge of the SBAR was 3.26, Attitudes towards SBAR scoring 3.31, Critical thinking disposition scoring 3.50. Knowledge of the SBAR(r=.46, p<.001) and Attitudes towards SBAR(r=.23, p=.023) were significantly positive correlation with critical thinking disposition in nursing students. Therefore, to increase the critical thinking disposition of nursing students, It is necessary to develop the program for increase knowledge of the SBAR and attitudes towards SBAR of nursing students.

  • Chemicals are widely used throughout society, and usage is expected to increase in the future. As a result, various accidents related to chemicals and dangerous substances are occurring, and the frequency of occurrence is expected to continue to increase. Thus, it is expected that this study will present problems and improvement directions through analysis of each associated agency's accident report and management system, and improve the research input system to increase efficiency in collecting and statistical calculation of chemical and hazardous accident.

  • Accidents between ships occur frequently at the traffic congestion area. Once a maritime accidents occur, it is likely to end up with critical damaged accidents. This paper develop a simulator for assessing quantitative risk based on statical maritime traffic data and realtime traffic distribution. Ship's passage risk assessment simulator consist of import of division of passage data, traffic distribution analysis and passage risk assessment analysis. Maritime traffic data of WANDO waterway apply to simulator for calculation of quantitative risk rate of waterway.

  • Unexceedingly rapid industrialization in Korea produced not only the improvement of living standards but many side effects including safety problems. This study, utilizing the survey data on 800 respondents on the quality of life and psycho-physical safety, reveals several findings as follows: 1) safety is one of the key dimensions of quality of life, 2) people usually take an equilibrium between risk and safety, although the equilibrium point differs by culture, social system, and other demographic traits, 3) accidents can be classified into three different types, demanding a different approach on the cause process, and solution in safety-related accidents. Major findings of this study implies that for the improvement of the quality of life, we should prescribe different policy measures according to the three different types of accidents.

  • To reduce conducted a survey on human error risk factors and related experience frequency to drivers of Seoulmetro and Korail. The human error arising from systems operating urban railway aimed at eliminating and reducing the fundamental causes of urban rail accidents is based on research from a factorial point of view, since it contains problems dealing with the types and situations of accident generation. It is required to contribute to reducing human error so that urban railway accidents may be reduced and safe operation will be continuedly seared.

  • 해체공사는 작업의 특성상 단기간에 이루어지며, 해체공사 현장에 투입되는 근로자는 일용직 근로자가 대부분으로 안전사고의 비율이 높다. 사업장 위험성 평가에 관한 지침에는 위험성 평가시 근로자를 참여토록 하고 있으나 해체현장의 특성상 근로자가 참여한다고 하여도 위험요소를 파악할 역량이 부족할 따름이다. 또한 기존의 해체공사 안전관리 매뉴얼은 구조안전성 확보를 위한 매뉴얼로 해체 근로자의 안전을 위한 매뉴얼은 없는 실정으로, 근로자의 안전을 확보하기 위한 위험성 평가 매뉴얼이 요구되고 있다. 이에 본 연구에서는 건설공사 안전관리 종합정보망(CSI)의 해체 및 철거공사의 사고사례를 분석하였으며, 해체 및 철거 사고시 발생한 주요 위험요소를 도출하여 작업 공종별로 유해·위험요인의 파악을 손 쉽게 할 수 있도록 하였다. 또한 해체 현장 규모에 따라 대규모 현장은 빈도·강도법, 중·소규모 현장은 체크리스트법을 활용하여 위험성을 결정하고 감소대책을 수립할 수 있도록 매뉴얼을 구성하였다. 잔여 위험에 대해서는 관리카드를 만들어 해체공사 완료시까지 관리하도록 하였다.

  • The purpose of this study is to investigate the types of domestic safety accidents involving children and to verify the difference of safety knowledge according to variables of parents. Subjects include 226 parents who have 3-5 year old infants enrolled in kindergartens and day care centers in I-city, Jeollabuk-do. The study tools are modified and complemented questionnaire for the study purpose referred to the preceding research data and the literature. For the processing of collected data, frequency analysis, descriptive statistics, one-way ANOVA, and the Duncan post-test were utilized using the SPSS program. The results of this study are as follows: First, safety accidents occurred at the majority of homes which have infant children. On average, the occurrence frequency was 1.78 times per six months. The accidents involving infants occurred in the order of drop or slip, crash or impact, stricture or jamming, fall, stab or cut, burn, swallow or inhalation. Second, both parents had an average level of safety knowledge. There was a distinction in the areas of 'fall' and 'first aid' according the mother's age. In addition, stay-at-home mothers had the higher level of safety knowledge compared with working mothers in the areas of 'general safety knowledge' and 'fire'. There was a distinction in the area of 'fire' according to the father's age. Given these findings, safety training programs for parents to improve safety knowledge needs to be developed.
