Background: Workers are exposed to several risks in academic laboratories due to the presence of potentially hazardous substances. The main objective of this study was to assess the prevalence of accident occurrence and associated risk factors among laboratory workers at the scientific laboratories of the public university in Lebanon and the impact of safety measures training and availability. Methods: In this observational study, a survey was conducted for one year in scientific laboratories at faculties of the public university. Results: Among the participants (N = 220), 45.0% have had accidents; the main cause was exposure to chemicals (73.7%) and more specifically by inhalation (45.4%). Females (85.9%) were more exposed to accidents than males. Laboratory workers with a master's degree, a full-time schedule, and more than ten years of experience were significantly more exposed to accidents (p < 0.05). A significant association was found between accident occurrence and training on management of hazardous products (p = 0.044), risks related to workplace (p = 0.030), eyewash and emergency shower (p < 0.001), first aid (p = 0.012), and facial protection availability (p = 0.019). In spite of the lack of safety culture and efficient training on laboratory safety, participants have shown a very good perception regarding safety measures to be applied in case of work accidents. Conclusion: Based on our findings, the prevalence of accident occurrence is elevated among lab workers at the public university. The impact of regular training on laboratory safety preventive measures is of great importance to ensure the efficiency of occupational health and safety in scientific laboratories.

우리나라는 세월호 사고 이후 해양안전에 대한 중요성이 증대되고 있다. 특히, 해양관련 종사자들에 국한하지 않고 대국민 해양안전의식 고취를 위해 학교 및 해양관련 단체에서 다양한 교육훈련 및 체험교육이 시행되고 있다. 선원의 안전교육은 SOLAS 규정에 의거 여객선은 10일, 상선은 매월 1회 소화 및 퇴선훈련을 실시하고 있다. 세월호 사고 이후 교육훈련의 효과를 증대시키기 위해 교육 정원을 기존 40명에서 20명으로 줄여 모든 교육생이 실제 교육훈련에 참여할 수 있도록 하고 있다. 현재의 교육훈련 형태는 교재에 의거한 이론교육 실시 후 실제 실습을 행하는 2단계 교육훈련이 실시되고 있다. 하지만 현재 인적, 물적 여건상 교육생들에게 많은 실습시간 부여 및 소수인원으로 구성된 실습교육이 곤란한 상황이나 시뮬레이션 기법이 도입될 경우 실습 전 숙달된 능력으로 실습교육의 빠른 진행으로 많은 실제 실습교육 수행이 가능할 것이다. 이러한 이유로 이 연구에서는 해상안전교육 중 소화훈련의 효율성을 증대시키기 위해 총 3단계로 구분한 교육훈련을 제안하고자 한다. 즉, 이론 교육 후 시뮬레이션 기법을 통한 개인별 임무 숙지 및 장비 사용법에 대한 이미지트레이닝교육을 추가하고자 한다. 이러한 시뮬레이션 기법을 사용할 경우 이론교육으로 얻어진 지식을 바탕으로 실제 훈련 전 가상으로 먼저 시행함으로서 실습교육에 빠른 적응이 가능하며 시뮬레이션 특성상 실제 훈련에서는 곤란한 긴급상황 대처훈련 및 다양한 시나리오에 의한 반복훈련이 가능하다. 이렇게 실습 전 숙달된 능력을 바탕으로 실습교육의 진행 속도를 증가시켜 많은 실제 실습교육을 수행할 수 있어 교육훈련 효율성이 증대될 것이다. 실제 교육생 설문조사에 의하면 개인별 실습시간 부족을 지적하였다. 이러한 이유로 가상현실 기법을 이용한 시뮬레이터 개발이 필요하여 이 연구에서는 개발방법에 대해 고찰하였다.

Background: This paper presents the findings of a pilot research survey which assessed the degree of balance between safety and productivity, and its relationship with awareness and communication of human factors and safety rules in the aircraft manufacturing environment. Methods: The study was carried out at two Australian aircraft manufacturing facilities where a Likert-scale questionnaire was administered to a representative sample. The research instrument included topics relevant to the safety and human factors training provided to the target workforce. The answers were processed in overall, and against demographic characteristics of the sample population. Results: The workers were sufficiently aware of how human factors and safety rules influence their performance and acknowledged that supervisors had adequately communicated such topics. Safety and productivity seemed equally balanced across the sample. A preference for the former over the latter was associated with a higher awareness about human factors and safety rules, but not linked with safety communication. The size of the facility and the length and type of employment were occasionally correlated with responses to some communication and human factors topics and the equilibrium between productivity and safety. Conclusion: Although human factors training had been provided and sufficient bidirectional communication was present across the sample, it seems that quality and complexity factors might have influenced the effects of those safety related practices on the safety-productivity balance for specific parts of the population studied. Customization of safety training and communication to specific characteristics of employees may be necessary to achieve the desired outcomes.

Background: Effective policy implementation is essential for a healthy workplace. The Ryan-Kossek 2008 model for work-life policy adoption suggests that supervisors as gatekeepers between employer and employee need to know how to support and communicate benefit regulations. This article describes a workplace intervention on a national employee benefit, Family and Medical Leave Act (FMLA), and evaluates the effectiveness of the intervention on supervisor knowledge, awareness, and experience with FMLA. Methods: The intervention consisted of computer-based training (CBT) and a survey measuring awareness and experience with FMLA. The training was administered to 793 county government supervisors in the state of Oregon, USA. Results: More than 35% of supervisors reported no previous training on FMLA and the training pre-test revealed a lack of knowledge regarding benefit coverage and employer responsibilities. The CBT achieved: (1) a significant learning effect and large effect size of d = 2.0, (2) a positive reaction to the training and its design, and (3) evidence of increased knowledge and awareness regarding FMLA. Conclusion: CBT is an effective strategy to increase supervisors' knowledge and awareness to support policy implementation. The lack of supervisor training and knowledge of an important but complex employee benefit exposes a serious impediment to effective policy implementation and may lead to negative outcomes for the organization and the employee, supporting the Ryan-Kossek model. The results further demonstrate that long-time employees need supplementary training on complex workplace policies such as FMLA.

In laboratories, researchers frequently work using new methods with new tools and materials. So the workers in laboratories are exposed to risk from dangerous articles all the time. In the case of university laboratories, testing is done by the individual at night. Because of that, the risks in university laboratories are higher than in other places. In addition, students and managers in universities generally have little concern for laboratory safety. So students are sometimes injured or killed in laboratory accidents. In this study, 1,000 university students answered questions about university laboratory safety. Their answers have been analyzed to determine the state of actual conditions and to formulate countermeasures. The results indicate that we need to change the safety awareness of the universities and the students. Adequate safety training and safe practice must be implemented by each university to decrease accidents. Development of systematic safety training program suited to the specific conditions of the individual laboratory and formulation of specific counter plans should accidents occur are required.

Objectives: This study compares the differences of fit factors before and after training on the N95 mask. The results will be utilized to suggest the need of providing effective training on respirator use. Methods: A total of 49 study subjects were tested, comprised of nurses from a general hospital and undergraduate nursing students from a medical school. Anthropometric measurements of face length and face width were compared with the NIOSH(National Institute for Occupational Safety and Health) panel. Fit factors(FF) were measured with TSI Portacount Pro+8038 before and after on-site training regarding the proper use of respirators. The FF pass/fail criterion was set at 100. Results: Two subjects(4.1 %) passed the fit test before training on use of the N95. However, 36(73.5%) of the 49 passed the test after training. Overall the FF(GM(GSD)) was 13.4(3.2) before training, but improved to 106.6(2.1) after training, which was statistically significant. These findings suggest the efficacy of educational intervention, and the performance of the direct on-site training proved to be better than that of the traditional educational methods. Conclusions: This study showed the effect of on-site training of the N95 respirator among health care workers(HCW). Therefore, providing effective training on the use of N95 for HCWs before their work assignments will greatly reduce exposure to harmful agents. It is recommended that fit testing be mandated to check for adequate protection being provided by the given respirators.

Purpose: This study was aimed at developing a tractor-driving simulator for the safety training of agricultural tractor operators. Methods: The developed simulator consists of five principal components: mock operator control devices, a data acquisition and processing device, a motion platform, a visual system that displays a computer model of the tractor, a motion platform, and a virtual environment. The control devices of a real tractor cabin were successfully converted into mock operator control devices in which sensors were used for relevant measurements. A 3D computer model of the tractor was also implemented using 3ds Max, tractor dynamics, and the physics of Unity 3D. The visual system consisted of two graphic cards and four monitors for the simultaneous display of the four different sides of a 3D object to the operator. The motion platform was designed with two rotational degrees of freedom to reduce cost, and inverse kinematics was used to calculate the required motor positions and to rotate the platform. The generated virtual environment consisted of roads, traffic signals, buildings, rice paddies, and fields. Results: The effectiveness of the simulator was evaluated by a performance test survey administered to 128 agricultural machinery instructors, 116 of whom considered the simulator as having potential for improving safety training. Conclusions: From the study results, it is concluded that the developed simulator can be effectively used for the safety training of agricultural tractor operators.
