Purpose: Study purpose was to describe the child safety injury experiences, injury prevention behaviors and educational needs of immigrant Vietnamese women on Jeju Island, and to explore associations among those factors. Methods: A descriptive correlational study was conducted using structured questionnaires to collect data from immigrant Vietnamese women who visited a multicultural centers on Jeju Island from January to April, 2017. Results: Data from 60 women were analyzed. They were $28.2{\pm}5.5$ years old, had resided in Korea for $40.6{\pm}31.1$ months, and had $1.5{\pm}0.6$ children on average. In total, 51.7% had previous injury prevention education, 68.2% had experienced child safety injuries, and 95.0% wanted to receive education on how to prevent child safety injuries. The mean total score of child injury prevention behaviors was $27.33{\pm}17.79$, and that variable was associated with a longer duration of formal education (t=2.41, p=.021) and with women's experiences of child safety injury (t=5.97, p<.001). Conclusion: Immigrant Vietnamese women experienced a higher frequency of child safety injuries and needed educational opportunities to prevent these injuries. Further research is necessary to develop the essential content and effective methods for education on child safety injury prevention among this unique multicultural population.

This study deals with characteristics and risk of a PM based on user survey result, road driving test and data analysis of PM accident. Text mining method is applied to extract PM accident data from Big Data, which are claim data of private insurance company. Road driving test and survey on safety, convenience, noise, overtake ability, steering ability, and climbing ability of PM are performed to evaluate user's safety and convenience considering domestic road condition. As the result of claim data analysis, annual average increase rate of PM accident is 47.4% and average compensation of personal mobility is higher than that of bicycle by maximum 1.5 times. 79.8% of PM accident is self-caused accident due to unskilled driving and age-specific diagnosis rate of driver over 60 is higher than that of under 60. Diagnosis rate of over 60 at lower limb, foot, rib and spine is especially higher than that of under 60. As the result of road driving test and user survey, satisfaction level on safety and convenience of PM is evaluated as close to that of bicycle and satisfaction level of PM is increased after boarding. Overtake ability, steering ability, and climbing ability of PM are evaluated as same or better than that of bicycle but warning equipment to pedestrian or bike such as horn is required because noise level of PM during driving is too low. Finally, user survey result shows that bicycle road is suitable for PM and safety standard, advance-education and insurance are required for PM. It is suggested that drivers' license for PM can be replaced by advance-education. Results of this study can be used to prepare safety measures and legal basis for PM operation.

오늘날과 같이 시스템의 복잡화에 따른 고가의 시스템 구입비, 크기 및 중량의 허용한계 등과 같은 여러 제한요인 때문에 고도의 신뢰성 있는 무기체계 개발을 위해서는 무기체계 개발과정의 전 순기 동안에 시스템 안전(system safety)분야의 적용이 불가피하게 되었다. 시스템 안전에 관한 연구는 매년 증가하는 사고로부터 발생하는 엄청난 손실을 줄여보자는 필요하에 1960년 경부터 미국의 군대에서 시작되었다. 1969년 7월 미국 군사표준서MIL-STD-882(시스템 및 관련 부시스템에 대한 시스템 안전 프로그램 요구조건)가 제정된 이후 요즈음 미군의 방산물자 조달 및 획득시 시스템 안전분야 적용이 의무화되어있다. 시스템 안전분야는 개발중인 시스템의 설계, 개발, 운용과 관련된 여러 분야, 즉 품질보증, 인간공학, 시스템공학, 형상관리분야 등과 상호 밀접하게 연관되어 있으므로 이 분야에 대한 상호 이해와 끊임없는 정보교환이 요청되고 있다. 시스템 구성분야별, 무기체계 개발단계별로 조직적으로 분석된 시스템 안전결과를 토대로 프로 젝트 관리자(PM)는 개발중인 무기체계 시스템에 내재된 시스템 위험을 어느 수준까지 수용할 수 있을 것인가에 대한 현명한 판단을 내릴 수가 있게 되는데 항공기개발 프로그램의 경우 시스템 안전의 궁극적인 목표는 성공적인 초도 비행이라고 할 수 있다.

After Fukushima Nuclear Accident on Mar11, 2011, to grasp the thought of university students in Korea on radiation and medical radiation and seek for the right mass communication on the radiation safety of the people and the proper teaching method on radiation, 790 questionnaires from the universities which had a four-year department of radiological science in 5 provinces(Gyeonggi, Gangwon, Chungcheong, Jeolla, and Gyeongsang-do) all over the country were collected and analyzed. The questionnaire was composed of 36 items, and it was analyzed that one of the important causes that made them feel that radiation was dangerous was 'even if they were exposed to the small quantity of radiation, they could have trouble later.' ($3.28{\pm}1.05$). In the item of the control of radiation, there were the respondents who answered that the government should take action rather than an individual($3.87{\pm}0.89$). In the item of 'Fukushima Nuclear Accident made me think that 'We should not keep nuclear power generation', the result was $2.79{\pm}0.95$. In the item of 'My thought on the medical radiation has negatively changed since Fukushima Nuclear Accident', the students who hadn't taken the course related with radiation showed a negative thought on the medical radiation, such as, there was $2.64{\pm}1.02$ as a whole, $2.31{\pm}1.00$ in department of radiological science, $2.94{\pm}0.95$ in department of dental hygiene, and $3.13{\pm}0.82$ in other departments. And also, those who thought that the education of radiation was necessary were 82.28%, and T.V or Internet was thought as the most effective teaching method.

Divers types of Personal Mobility(PM) are appeared on the market after the Segway is introduced. PMs have propagated very rapidly with their ease of use, and accidents related with PM show a sudden increase. Many studies on the PM are performed as its trend, but dring safety of passengers are excluded. In this study, criteria which can be adopted for PM's driving safety evaluation are reviewed. Also result of driving safety evaluation on 3 types of PM(wheel chair, kickboard, scooter(seating/standing) and walking using deducted criteria is given. COG(Center of the gravity) and SM(Stability Metric) are finally selected two criteria among many of them used in other fields. COG indicates how the center of mass deviates from the direction of the gravity. SM is a normalized value of generated force when PM moves as internal force, angular momentum, and ground reaction force. 0 means stop, and negative value means rollover, so it can be used for safety evaluation of PM. Average and standard deviation of measurement are standard of safety on the COG analysis. Wheel chair is the most safe and kickboard is the most unstable on the COG analysis. Wheel chair is also ranked as top safe on the SM analysis. Among two riding types(seating and standing) on the scooter, seating type is evaluated more safer than standing type. It is proposed that more various type of PMs are need to get safety evaluation for drivers and devices themselves together.

This study surveyed the change of housewives' purchase behaviors by food safety incidents; the outbreak of 2008 Melamine incident in Korea as for example. 565 housewives in Gunsan were interviewed in March 2009. 52.3% of respondents were regarded as unsatisfactory for food safety management in Korea. Despite the result of scientific assessment for melamine, 74.6% of respondents were yet regarded as health-threatening substance. By the point of before, during and after Melamine-related food safety incident, we were surveyed the level of purchase for melamine-related food items as five scales, the results were $2.47{\pm}0.97$, $1.80{\pm}0.92$ and $1.62{\pm}0.92$, respectively (p < 0.001). After the incident happened, the purchase level was even more reduced. This study also found that there were significance difference (p < 0.05) among the respondents' knowledge for melamine toxicity and food safety management in Korea concerning housewives' purchase behaviors, i.e. the more accurately for melamine toxicity and higher satisfactory of consciousness of food safety, there were less change of purchase behaviors. In conclusion, the consciousness of food safety and accurate knowledge of hazards were significantly affected for the change of housewives' purchase behaviors by food safety incidents. Therefore, it can be suggested that the need for more scientific risk communication strategies with consumer.

Recently, there has been an increase of accidents related to the rise in the use of Personal Mobility Vehicle (PMV). To solve this problem, the National Assembly announced an amendment that restricted the use of PMV to bicycle roads and to prohibited for people under 13 years old to use PMV, but there is no detailed information about travel speed and safety. In this study, a survey was conducted by dividing the group into minors and adults based on the age of obtaining a driver's license to find out the direction of improvement of laws and systems about PMV. Our results showed that adults considered PMV as more dangerous (Adults 5.50, Minors 4.94) and the suggested age for PMV use was lower from minors than adults (Adults 15.70, Minors 13.85). We found that proper travel speed on bicycle roads differed according to the presence of a driveway (Driveway 26.21 km/h, Non-Driveway 23.55 km/h) and minors had higher a travel speed than adults on all types of bicycle road. Also, Helmets for PMV were seen as the most important safety equipment on all types of bicycle road. and the importance of other safety equipment differed according to the presence of a driveway (Driveway Front-Lighting, Non-Driveway Car Horn). Through this study, It proposes that we have to make new regulations about the use of front lights and horns, as well as enforcement measures that differentiate the speed on each bicycle road type as a way to improve the laws and systems for PMV.
