This study was carried out with the purpose of understanding burdening characteristics of electronic assembly process and suggesting improvement method of ergonomic work suitable for electronic assembly process. In this paper, the workplace that is the subject of the study is an electronics manufacturing factory located in Suwon, Gyeonggi-do. It is a large-scale TV manufacturing factory that has the greatest potential for burdening posture among various products. Respectively. Analysis of the symptom questionnaire and ergonomic work analysis results showed that most of the electronic assembly process was a burden on the shoulders, legs, feet, hands, wrists, and arms due to the work characteristics of using the upper legs in the posture , It is more appropriate to perform job analysis evaluation with RULA and REBA rather than OWAS in which hands, wrists, and arms are not included in the evaluation items, because the electronic assembly process uses mostly hand / wrist / Could know. Based on the ergonomic work design criteria, it is estimated that the risk of musculoskeletal diseases in the electronic assembly process will be reduced if the work process is designed by presenting the floor plan and side view in the work process improvement plan. Since the research scope of this study is limited to the electronic assembling process of a specific company, it can be supported by the results of this study if generalization is applied widely to the work processes of other industries. It is expected to be possible.

This study aims to figure out the effective methods for reducing industrial accidents through establishing safety culture ultimately among new employees in the construction industry. It is reported that the new staffs, especially those who are working less than a year have accounted for a large portion of accidents such as falls and collapse at the construction site. Amid this situation, the preventive measures to lower the rates of industrial accidents should be urgently needed. In this regard, the newly hired staffs were given a form of survey to analyze the interaction with safety consciousness, safety training, safety procedures and safety actions in establishing safety culture. The results of the survey demonstrated the efficiency of the safety culture training in that the new workers showed more positive attitude towards safety awareness after they took a safety culture training than before they did. The output throughout this study verifies that safety consciousness, safety knowledge, safety training, safety procedures and safety actions are intimately connected to one another and these factors have a positive influence on the new staffs' attitude and awareness of safety culture at the job site. Thus, the implication of this study suggests the safety culture training, which is included with safety consciousness, safety knowledge, safety procedures and safety actions should be a possible measure to instill safety consciousness and raise safety awareness for the new employees. Then, it is expected that effective safety culture training ultimately lead to the spread of the new safety culture in the construction field.

The purpose of this study is to discover the key factors to prevent unsafe behavior of a construction worker. Industrial accident statistics in 2013 show that the mortality of construction workers is highest and Heinrich said that most of the accidents caused by unsafe behavior. Installation of safety facilities and safety training in construction sites have improved a lot compared to the past but disaster caused by the unsafe behavior of workers are still occurring at the construction sites in all over the country. This study attempts to investigate the causes and present countermeasure of unsafe behaviors of construction workers. It showed that self management, personal nature of the workers, relief of stress, improvement of work environment are needed most in order to avoid unsafe behavior thorough this study. The output throughout this study are as follows the first securement of optimal construction period, the second education and observation about workers in their fourties and unskilled workers, the third improvement of working environment, the fourth, obey of safety rule, the fifth, drastic safety inspection, the sixth stress relief of workers, the seventh self-control safety management. Based on these findings I anticipate that this study will become a practical guideline to prevent unsafe behavior of domestic construction workers and experimental research for proving effectiveness of the guidelines is done and to be foundation to eradicate unsafe behavior in the construction industry.

The study collected questionnaire and conducted statistical analysis on 474 workers in order to ascertain the effect of day-to-day construction field worker's safety climate, environmental satisfaction, and safety awareness on the exposure to musculoskeletal disorder. First, a large number of construction worker's general characteristics are found to be a male, age of above 51 and below 60 years old, married, high school graduate, and smoker and drinker. Second, it is found that in exposure characteristics of musculoskeletal disorder. It is found that 57.8% of workers have experienced accidents in the past, and their injury position is the highest in the order of shoulder, arm/elbow, and 31.4% are still under medical care or doctor's observation. Third, the study analyzed that the total NIOSH standard based musculoskeletal disorder related subjective symptom patients are 24.1%, where NIOSH standard 1 based weak pain complainers are 8.4%, NIOSH standard 2 based mid-level pain complainers are 7.2%, and NIOSH standard 3 based acute and extremely acutre pain complainers are 8.4%. Fourth, safety climate has been categorized and designated by each factor: factor 1 is 'safety climate for work', factor 2 is 'safety motive at work', factor 3 is 'safety attitude at work', factor 4 is 'safety behavior at work', factor 5 is 'safety procedure at work', and factor 6 is 'safety culture satisfaction'. The environmental satifaction is also designated as following factors: factor 1 is 'general environmental satisfaction', factor 2 is 'physical stress', factor 3 is 'phyical work environment', factor 4 is 'social work environment', and factor 5 is 'mental stress'. Fifth, the total average of safety climate is 3.13 point with the highest point earned being safety culture satisfaction of factor 6 with 3.16 point, the total average of environmental satisfaction is 2.71 point with the highest point earned being general work environment satisfaction of factor 1 with 2.76, and the total average of safety awareness is scored as 3.17 point. Sixth, the analysis highlight that non-patients of NIOSH standard based musculoskeletal disorder have higher satisfaction in all safety climate, environmental satisfaction, safety awareness when compare to that of NIOSH standard based musculoskeletal disorder patients. Seventh, the 'safety climate of work'(factor 1) of safety culture climate factor affects 1.384 times more on the non-patient than to the patients, and 'general work environment satisfaction'(factor 1) of environmental satisfaction affects 2.320 times more on the non-patient than to the patients. The study highlights that the safety climate and environmental satisfaction of the day-to-day construction workers are verified to be much higher for non musculoskeletal disorder patients than that of musculoskeletal disorder patients, and that patients' awareness is low on these factors.

This research has established its hypothesis that railway safety accidents caused by railway staff’s human error influences the safety consciousness due to job stress and railway safety culture. Hence, through analysis on railway staff’s job stress, safety consciousness, and railway safety culture conditions, the study has analyzed the Impact of job stress factors on safety consciousness and railway safety culture as well as correlation among job stress, safety consciousness and railway safety culture, thereby aiming to prevent railway accidents caused by human errors and to research and suggest improvement measures to the identified problems. The research results are as follows. In regards to safety consciousness, the result of comparative analysis on railway staff and construction workers’ safety consciousness illustrates greater level of safety consciousness from railway staffs. However, safety consciousness for light injury was displayed to be higher among construction workers. In regards to safety consciousness of railway staff due to job stress level, the result demonstrated that greater level of job stress led to more negative effect on the worker’s safety consciousness. In terms of railway worker’s safety consciousness conditions, it was shown that they lack motivation as railway managers to improve railway practices that may pose threats against railway safety, display insufficient communication or discussion on railway safety, and are inclined to regard productivity with greater significance than railway safety. The railway staff pointed out that railway safety trainings are far less capable of preventing safety accidents. As a result of analyzing the correlation between safety consciousness and railway safety culture, the researcher was able to identify factors with significant correlations and therefore discovered a significant correlation between safety consciousness and railway safety culture. In conclusion, through this study, no serial correlation between job stress, safety consciousness and railway safety culture was identified, it has successfully drawn the result showing significantly positive correlations between the variables that serve an evidence of the research hypothesis. In addition, the improvement measures for railway safety were deduced as follows through this study. First, there is a necessity for enhancement in communication in order to allow active discussions on railway safety issues among railway workers. Second, there is a need for improvement in facilities and equipment for railway safety accident prevention. Third, it was deemed necessary to reconsider railway safety training. Fourth, it was identified that there is a lack of compensation system that encourages railway workers’ voluntary effort on railway safety, pointing to the necessity of measures to motivate railway workers’ participation in improvement activities on railway safety.
