제조업 야간작업이 근로자의 안전행동과 안전의식에 미치는 영향

Abstract

There are many problems caused by highly sophisticated industry's night work, a typical problem is the physiological discord caused by the reversal of worker's circadian-rhythms. Another problem is the burden caused by changing between day and night work, and the damage of this caused to the workers' social life. There is a decline in the concentration which caused a decline in work performance and a rising errors which can lead to more industrial accidents. It was reported that if the quantity and quality of sleep is not adequate, it causes drowsiness during the day or night work. And this drowsiness causes a decline in concentration which leads to low work performance and it has a bad effect on workers' normal life. Eventually, a decline in the quality of life and an increase in the rate of industrial accidents is noticeable. It has generally been reported that night work leads to lack of sleep, tiredness, stress, family discord, a loss of communication skills, and these are known as emerging problems in the industrial work place. Previous studies on shift work and night work have been reported a higher risk factor for the workers. Research indicates that they deal with problems such as sleep disorders, tiredness, stress, physical and mental health issues. The objects of the previous studies also included people such as nurses, fire fighters, police officers and most of service sector. The problem is that the previous studies did not include the impact on the workers concerning safety of workers in the field of manufacturing due to the changing between day and night work; a research concerning the impact on the workers is lacking. Therefore, because of the lacking information concerning night workers, this study proposes to focus on the characteristics concerning night workers. This study conducted and investigated on the impact of safety behavior and safety consciousness by workers during the night work. A current management plan exists including safety priorities of night workers. The questionnaires used in the study focused on these safety priorities to try to identify the most important ones that are relative to the factory workers who work at night. And, we used AHP techniques to figure out. Significant influence factors on the impact of working conditions to workers' safety behavior and safety consciousness and priority as a result of the AHP technique proposed management plan priority factors by comparing the results of the two of the analysis presented above were compared and verified, and for those through T-test and analysis of variance; the results were presented according to demographic factors. According to the results of demographic factors, the management measures were proposed in order to improve the safety of night work. As the result of regression analysis, the working conditions of night work affects the safety behavior and safety consciousness of night workers. From the study, we can conclude that the most influential factors to improve safety of night workers were break time, work time, monetary compensation, and work load. And also from the general result, it became clear that the most influential factors to improve the safety of night workers were break time, work time, work load, and monetary compensation in that specific order. After, examining the result from AHP analysis, it became clear that management so important factors. The important factors as break time, work time, monetary compensation, and work load does indicating different order in the importance. However, we can see these four factors are key to improve safety of night workers. In addition, according to the result of analysis of level differences, there was a difference in response by workers depending on gender, age, work experience, night work career, employment patterns, smoking, alcohol and coffee consumption. Therefore, the results of this study were similar to the results of the preceding study to take into account the age and gender of night workers, it was able to conclude that it could improve the safety of night work by managing break times, work time, work load, and monetary compensation depending on the workers' gender, age, work experience, night work career, employment patterns, smoking, alcohol, coffee consumption.
