  • This study analyzed the physical changes in 119 paramedics transporting equipment at the emergency site and performing post-cardiopulmonary resuscitation through experiments. First, the average heart rate increased by about 25 times comparing CPR was performed without physical load and with personal protective equipment after moving equipment. In the third quartile, it increased to about 27 times. Second, when CPR was performed without physical load, and CPR was performed after moving the equipment with personal protective equipment, both the body temperature was raised and the rising body temperature was measured within normal body temperature. Third, the change in respiration rate increased by 7 times on average comparing CPR was performed without physical load and CPR was performed after moving the equipment while wearing personal protective equipment. In the third quartile, it increased to about 11 times. Finally, the change in blood pressure increased by 26.6 mmHg on average comparing CPR was performed without physical load and with wearing personal protective equipment after moving the equipment, and increased by 31.2 mmHg on average in the third quartile.

  • 본 연구의 목적은 충남지역 남녀대학생의 식품위생안전인식, 식품위생태도, 개인위생관리에 관한 실태를 조사하여 식품위생안전교육에 필요한 기초자료를 제공하는 것이다. 2019년 5월 16일부터 6월 30일 까지 충남지역 H 대학교의 학생을 대상으로 수집한 총 1,048부를, SPSS 23.0을 이용하여 통계 분석하였다. 본 연구 결과, 식품위생안전인식부분에서, 남학생은 여학생보다 유의하게, 우리나라에서 판매 유통되는 농축수산물(남, 여)(3.37, 3.08)과 가공식품(3.40, 3.00)이 더 안전하다고 생각하고, 식품안전에 대한 정보를 얻기가 더 쉽고(3.33, 2.98), 안전한 식품을 고를 자신이 더 있다(3.30, 2.97)고 응답하여, 남학생이 여학생보다 식품위생안전인식이 더 높은 것으로 나타났다. 그러나 식품위생태도 부분에서는 여학생이 남학생보다 더 식품구입 시 유통기한을 확인하여야 한다(남, 여)(4.11, 4.40), 식품의 특성에 맞게 냉장 냉동보관 저장하여야 한다(4.08, 4.30)고 응답하였고, 개인위생관리부분에서도 여학생이 남학생보다 화장실을 사용한 후 손을 씻어야 한다(4.23, 4.53)에 더 높게 응답하여, 여학생이 남학생보다 식품위생태도와 개인위생관리에 대한 인식이 더 높은 것으로 나타났다. 본 연구 결과 충남지역 대학생들의 식품위생안전, 식품위생태도, 개인위생관리에 대한 인식은 성별 간 유의미한 차이를 보였으며, 남학생이 여학생보다 식품위생안전인식은 더 높은 반면, 식품위생태도와 개인위생관리에 대한 인식은 오히려 더 낮은 것으로 나타나, 이러한 성별 간 차이를 고려한 차별화된 식품위생안전교육이 필요함을 제언한다.

  • This study was conducted to examine the usage effects of an augmented reality head-up display (AR-HUD) system on the risk perception and psychological changes of drivers. To do so, we conducted an experiment to collect the driver response times for vehicles and pedestrians as their risk perception behavior, and used a driving behavior determinants questionnaire consisting of Problem Evading, Benefits/Sensation Seeking, Anti-Personal Anxiety, Anti-Personal Angry, and Aggression factors for collecting the psychological characteristics of the drivers. Thirty drivers were randomly assigned into an in-vehicle AR-HUD using group and a control group. As a result, the Anti-Personal Anxiety and Anti-Personal Angry factors were negatively correlated with the response time for the control group. In contrast, these results were not shown for the in-vehicle AR-HUD system using group. These results indicate that the in-vehicle AR-HUD system may partially induce a relaxation of tension or stress for drivers with a high level of interpersonal anxiety. Therefore, the in-vehicle AR-HUD system might contribute to not only the visual safety driving behaviors of drivers, but also to their psychological driving safety with specific characteristics.

  • This study was carried out to investigate the children's knowledge, attitudes and practices of food safety. A total of 355 data were collected from elementary school students. The concern of food safety was moderate in 5 point Likert scale and relatively high correlated with food safety knowledge(r=0.571) and education(r=0.534). The experience and knowledge of terminology on food safety were estimated. The level of food safety was classified into 5 groups and the consideration of food purchase was classified into 3 groups by factor analysis. A few children were aware of the food safety knowledge and could hardly understood English terminology. And the food safety practices were surveyed, and most of children checked with expiration dates and packaging conditions of food. Personal hygiene practice of children was significantly affected by gender, self hygiene evaluation and the knowledge level of food safety. Providing more food safety information affects personal hygiene and the practices of food purchase, so educational programs on food safety for children were required.

  • Recently, personal characteristics of organizational members arc regarded as an important factor that affects performance of organization. In addition, job stress is attributed to one of main factors that result in poor work ability and high turnover rate. In this study, job stress, work ability and DISC personality types were surveyed targeting 292 of foreman in shipbuilding company. The relationships between job stress and personal characteristics including personality types and correlation between job stress and work ability were analyzed based on the result of survey. As a result of statistical analysis, there were six statistically significant relationships between job stress and age, job tenure, work type, hobbies, exercise, personality types. On the other hand, there was a statistically significant relationship between work ability and exercise. Furthermore, negative correlation between job stress and work ability were found. In accordance with these analysis, this study presented how to improve work ability by managing job stress items and personal characteristics that affect the stress and the stress level.

  • Construction sites have gradually become bigger and bigger according to Korea economic growth. Also use of tower crane and other heavy equipment has been increased. The increased use of heavy equipment like tower crane is leading to fatality incident. This study will verify hazards to influence tower crane incident through structural and positive verification and find which hazard influence incident risk. The result of this study is as follows. First, while there is a significant difference between safety managers and tower crane operators for working environment, safety management, personal manage among risk factors, we can not find any evidence on the difference in perception of tower crane incident risk between them. Second, task manage risk and personal manage risk has a significant positive effect on perception of tower crane incident risk. Third, while site environment risk has a significant positive moderating effect of task type between risk factors and perception of tower crane incident risk, personal environment risk has a significant negative moderating effect between them.

  • 대형 및 복합 화재에 효과적으로 대응하기 위해서 화재 현장에 대한 다양한 컨텍스트를 고려하여 표준작전절차 및 매뉴얼을 기반으로 최적의 대응 방안을 도출해야 한다. 이러한 의사결정을 긴급한 상황에서 신속하고 정확하게 수행하기 위하여 화재 상황 및 관련 대응규칙을 자동으로 분석하고 대응절차를 선제적으로 제시하는 방법이 필요하다. 이를 위해 이 논문에서는 공간정보 및 화재안전정보를 이용하여 규칙 기반으로 화재 대응 의사결정을 지원하는 방법을 제안한다. 제안하는 방법에서는 소방대상물의 실내외 공간정보 및 다양한 화재안전정보를 기반으로 화재 상황의 가변성을 모델링하고 이를 참조하여 화재 대응규칙 명세를 개발한다. 그리고 의사결정 시 주어진 상황에 맞게 가변성을 선택하고 룰 엔진을 통해 대응규칙을 실행하여 대응절차를 도출한다. 제안하는 방법을 재난현장 표준작전절차의 대상물별 표준작전절차를 대상으로 적용하여 실현 가능성을 검증하였다.

  • Object: we investigated some factors which can affect workers' comprehension of chemical hazard information and their actions to protect themselves from the hazard. Method: Comprehension score of chemical hazard information and the rate of wearing personal protective equipment (PPE) was surveyed for the 109 workers from 15 factories who were exposed to N, N-dimethylformamide. Difference of the worker's comprehension score of hazard information was analyzed by education interval, work duration and the way of occupational safety and health management between self-managed or sub-contracted. Result: Mean comprehension score of N, N-dimethylformamide hazard, which was given as a short quiz composed of 10 "true" or "false" problems, was 65%. Mean percentage of wearing PPE was improved as the education program was done within a month but decreased after 6 months. Eighty seven % of workers got the chemical hazard information from the material safety data sheet placed at workplace. Conclusion: Education interval and comprehension score affected the rate of wearing PPE. The way of occupational safety and health management self-managed or sub-contracted did not affect the workers' comprehension score on hazard information nor the rate of wearing PPE.
