Depending on changes in industrial structure, industrial accident preventive measures have been developed in various forms. The focus for prevention of industrial accidents had been changed from part of the hardware to behavior and consciousness of workers. According to the change of focus, Korea's industrial accident preventive measures also has been adjusted to voluntary safety and health considering the safety culture and such attempts of preventive measures has contributed for reducing the accident rate. Safety culture is difficult to access due to the fact that factors that make up the safety culture are comprehensive and varied and there are many of external factors that affect to the safety culture. Moreover, there is a limit for applying specific preventive measures. Because, management culture or value of enterprises is various depending on each country or region. Nevertheless, looking at previous studies of advanced countries, they are presenting the fact that safety leadership has greater influence to formation of the safety culture. As a result, we study the Influence of manager's safety leadership that effect on safety culture. we want to propose the way to activate safety culture in workplace and to contribute for safety culture research.

In road work zones, pedestrian workers' habituated inattention to warning alarms from construction vehicles can lead to fatal accidents. Previous studies have theorized that human factors such as personality traits may affect workers' inattentiveness to workplace hazards. However, there has been no study that directly examined how road construction workers' personality traits affect their attention to warning alarms within a work zone and the likelihood of engagement in a struck-by accident. This study examines how workers' sensation-seeking (especially boredom susceptibility) is related to inattention to warning alarms while performing a task in road work zones. An experiment with actual road construction workers was conducted using a virtual road construction environment. Workers' attention to repeatedly presented warning alarms was measured using eye-tracking sensors. In response to workers' frequent inattentive behaviors, a virtual accident was simulated. Results revealed a significant association between boredom susceptibility and workers' engagement in the virtual accident, a consequence of inattentiveness to warning alarms. The findings suggest that workers' personality traits predispose them to tune out warning alarms and become vulnerable to accidents in road work zones. The findings of this study can be used to develop targeted interventions aimed at preventing workers' inattention to repeatedly exposed workplace hazards, thereby contributing to reducing fatal accidents in road work zones.

The purpose of this study is to analyze safety and health managers' perceptual maps on the effective educational contents and its methods of workplace safety and health education. Self-administered survey was successfully conducted to 582 workers who were 339 in manufacturing, 68 in construction, and 175 in service & others by industry classification. Survey sites were recruited based on business size, incidence of occupational accident, and compliance of workplace safety and health education regulation. Questionnaire included personal factors, workplace factors, and needs of safety and health education at work. Male workers were 85.3% and more than 50% were in their 30s and had university education. Overall needs of educational contents and its methods were greater in manufacturing and services than construction. Two dimensional properties of effective educational contents perceived were 'knowledge structure' which divided to safety and health, and 'behavior outcomes' which divided to indirect and direct. Two dimensional properties of educational methods were 'class activity' which divided to experience-based and verbal-based and 'class participation' which divided to passive and active. Effective educational contents and its methods perceived by safety and health managers commonly included the characteristics of direct, case-based, and participation.

The purpose of this study was to investigate the effects of a workplace-based work-conditioning program (WCP) on the management of work-related musculoskeletal disorders (WRMDs) in an automobile-parts manufacturing company. In total, 1,110 subjects with WRMDs participated in workplace-based WCP emphasizing function-centered management and ergonomics. We investigated the incidence of WRMDs variables (number of persons diagnosed with industrial accident-related WHMDs, number of cases of WRMD) and financial benefits (cost of workers' compensation insurance and lost work days related to WRMDs) per year before and after WCP. Additionally, we compared self-reported pain intensity and functional disability in subjects with musculoskeletal pain before and after the WCP. Pain intensity was measured using a visual analog scale (VAS), and functional disability was measured by the neck disability index (NDI) and the Oswestry disability Index (ODI). The number of person diagnosed with industrial accident-related WRMDs, the number of cases of WRMD, the cost of workers' compensation insurance and lost work days related to WRMDs per year decreased by 51%, 37%, 34%, and 47%, respectively, and VAS, NDI, and ODI scores decreased significantly after implementation of WCP (p<.05). Thus, the results of the present study suggest that function-centered, workplace-based WCP was effective in managing WRMDs at an automobile-parts manufacturing company.

Background: This study aims to assess whether the TSI PortaCount (Model 8020) is a measuring instrument comparable with the flame photometer. This would provide an indication for the suitability of the PortaCount for determining the workplace protection factor for particulate filtering facepiece respirators. Methods: The PortaCount (with and without the N95-Companion^TM) was compared with a stationary flame photometer from Moores (Wallisdown) Ltd (Type 1100), which is a measuring instrument used in the procedure for determining the total inward leakage of the particulate filtering facepiece respirator in the European Standard. Penetration levels of sodium chloride aerosol through sample respirators of two brands (A and B) were determined by the two measuring systems under laboratory conditions. For each brand, thirty-six measurements were conducted. The samples were split into groups according to their protection level, conditioning before testing, and aerosol concentration. The relationship between the gauged data from two measuring systems was determined. In addition, the particle size distribution inside the respirator and outside the respirator was documented. Linear regression analysis was used to calculate the association between the PortaCount (with and without the N95-Companion^TM) and the flame photometer. Results: A linear relationship was found between the raw data scaled with the PortaCount (without N95-Companion^TM) and the data detected by the flame photometer (R² = 0.9704) under all test conditions. The distribution of particle size was found to be the same inside and outside the respirator in almost all cases. Conclusion: Based on the obtained data, the PortaCount may be applicable for the determination of workplace protection factor.

Every safety and health activity relies to some extent on education and training. Through effective education and training, people learn how to recognize safety and health hazards and how to control them. Thus, in most cases education and training is the first step in an accident prevention program. In this study, we analyzed safety training course-compare with Industrial Safety & Health Act, KISCO and KISA's rules,-and applied to workplace. In the safety training of workplace on the ground of the Industrial Safety & Health Act, the ratio of periodic employee refresher training to the total training subjects is only 25% and it of supervisor training is 16.7%. The ratio of training implemented in workplace about Knowledge, Skill, Attitude is as follows Periodic update training ; 15.1% : 7.5% : 64.2% New employees training ; 15.7% : 5.9% : 58.8% Job-change training ; 32.6% : 23.2% : 39.5% Specific safety & health training : 34.8% : 8.7% : 45.6%.

This study was conducted in order to assist with infusing safety consciousness and resolving insensitivity towards safety for industrial accident in workers, managers and executives of chemical companies. Among many industrial accident prevention methods, Korea has been mostly taking an engineering approach of preventing industrial accidents by replacing old machines with risks of an accident and through new facilities and equipments. Through an attitude survey of workers in large scale chemical companies, this study wished to examine the fact that the biggest reason why the accident rate for the past 10 years has not decreased is because safety consciousness has not been established yet.

Background: Personal protective equipment (PPE) has been designed in such a way to reduce accident rates. Unfortunately, existing PPE is rather ineffective as it is not able to provide warning signals when hazard is around. The integration of intelligent systems is envisaged to increase the efficiency of existing PPE. Methods: This project designed a safety vest incorporated with metal detectors which can provide immediate warning to the field workers when there is metal hazard around. This product has greater freedom of design via smart manufacturing as it involves the assembly of few commercially available parts into a single entity. Briefly, the metal detector is a do it yourself (DIY) kit, and the safety vest is purchasable from any local market. The DIY kit was connected to a copper coil and being sewed into the safety vest. Results: The metal detector induces beeping sound when there is metal hazard around. A total of 121 engineering students were introduced to the prototype before being requested to answer a survey associated with the design. Respondents have rated >3.00/5.00 for the design simplicity, ease of usage, and light weight. Meanwhile, respondents suggested that the design should be further improved by increasing the metal detection range. Conclusion: It is envisaged that the introduction of this smart safety vest will allow the workers to carry out their duties securely by reducing the accident rates. Particularly, such design is expected to reduce workplace accident especially during night time at construction sites where the visibility is low.
