Risk Factors Affecting Subjective Symptoms of Fatigue Due to the Environment of High School Students’ Computer Workstation in the Republic of Korea

Abstract

Abstract. [Purpose] This study aimed to determine the risk factors influencing subjective symptoms of fatigue through computer workstation monitoring of Korean high school students.[Methods] Six-hundred and eighty-five high school students were surveyed, and the independent t-test and one-way ANOVA were conducted to determine subjective symptoms of fatigue according to gender and hours of computer use, respectively. Pearson correlation coefficients were calculated to examine the correlations between subjective symptoms of fatigue and computer workstations, and multiple regression analysis was conducted to determine risk factors influencing subjective symptoms of fatigue. SPSS 12.0 was used to conduct the statistical analysis.[Results] Subjective symptoms of fatigue were stronger among females than males. The longer subjects rested, the less the subjective symptoms of fatigue were. There were correlations between subjective symptoms of fatigue and computer workstations, and musculoskeletal symptoms turned out to be a risk factor influencing subjective symptoms of fatigue. [Conclusion] This study identified the factors influencing subjective symptoms of fatigue at computer workstations, and consequently, the need to create specialized computer environments within schools to minimize fatigue symptoms was recognized.

Risk factors associated with musculoskeletal symptoms in Korean dental practitioners

“…Prevention and management require investigation both of the incidence of MSD by job category, as well as of the basic causes 3 ) . Work-related MSDs are caused by various and complex factors 4 ) , which must be considered in order to identify the major causes, and to examine the associations among the factors causing the MSDs.…”

“…Dental practitioners reportedly have a higher likelihood of MSDs, because they work in a static posture using their hands and wrists, while their backs, shoulders, and legs are bent. In fact, 64–96% of dental practitioners reportedly experience MSD pain 3 , 4 , 10 ) . In dental hygienists, 60–69.5% reported that MSD pain occurred primarily in the hand and wrist regions, whereas in dentists, 36.3–60.1% and 19.8–85% reported that MSD pain occurred in the back and neck regions, respectively 4 ) .…”

Comparison of Orbicularis Oculi Muscle Activity during Computer Work with Single and Dual Monitors

“…Yoo et al 9 ) suggested that improved computer workstations could prevent musculoskeletal disorders. A previous study also found that differences in computer workstations were associated with differences in fatigue 10 ) . The present study found that the use of dual monitors increased orbicularis oculi activity; therefore, to decrease eye fatigue in computer users, computer workstations that use either a single monitor or identical monitors from the same manufacturer in a dual setup, are recommended.…”
