  • One of the major requirements in preventing Work-related MusculoSkeletal Disorders(WMSDs) is to know definitely what vigorous exertion requirements are contained in a job. This requires improved job analysis tools which can accurately evaluate potentially harmful stresses to the musculoskeletal system. But to simply evaluate the level of stress at a joint, or in a muscle is not enough to motivate job changes. Therefore, the development of ergonomic evaluation tools for the jobs are important to ergonomics. The main objective is compared of the results that made by the ergonomic evaluation tools (e.g., BRIEF and RULA) in actually shoes manufacturing. These were developed in the foreign. So, it is priory needed to research of the ergonomics about Korean characteristic work by physiology and biomechanics.

  • Objective: The aim of this study is to identify foot shapes of Korean male farmers by classifying their foot types using 3D scan data and analyzing the characteristics of each type. Background: The increasing demands for anthropometric information for the design of machinery and personal protective equipment to prevent occupational injuries has necessitated an understanding of the anthropometric differences to be found among occupations. Static stooped posture and squatting posture are so common in Korean farmers that anthropometric deformation in foot especially seems to occur easily. Method: 366 Korean male farmers volunteered for this study from 16 different farming villages nationwide from 2009 to 2011. Subjects were categorized into 4 age groups from 40s to 70s. Their right feet were measured by using 3D foot scanner, the anthropometric dimensions were composed of 40 items. Results: The 8 major factors affecting the foot shapes were extracted. From these factors the foot shape of Korean male farmers was classified into 3 Foot types. Foot type 1 showed severe deformation in toe 1, type 2 had a narrow shape and type 3 had a wider width for its length. Conclusion: There were some differences in foot shape and types between farmers and the public. The most characteristic foot type in Korean male farmers was type 3. Application: The results of identifying foot shapes of Korean male farmers might provide the useful information for designing ergonomic farm work shoes.

  • Objective: The study was performed to suggest factors to consider when making or selecting protective clothing to enhance farmers' health. The purpose of this study was to review and summarize the agricultural safety technology on clothing including hat, gloves, and shoes. Background: The farmers' work clothing has to meet a multitude of requirement. Risk factors in farm-work were identified by previous researches. Agricultural safety clothing needs to be introduced. Method: We reviewed previous papers regarding the agricultural workers' health, safety clothing to protect body from excessive heat and humid environment, ultraviolet(UV) protection, and hazardous body working postures. Also the UV cut effect, pesticideproof clothing, and preventable farm work related musculoskeletal disorders were discussed. Results: The agricultural safety clothing needs to be developed to provide comfort and to be resistant against heat. The UV protection function on skin and eyes has not been fully researched in safety clothing studies yet. Conclusions and Application: The farmers' work-related body posture needs to be studied in order to make and design agricultural safety clothing. The safety issues on agricultural work shoes are also needed to be included in future studies.

  • In this paper, we propose a stress analysis on foot by lifting task attitudes. Maximum force and peak pressure were measured on 8 body regions by Pedar system in order to analysis the stress which is affected by task style and angle on foot when Manual Materials Handling task. As for the peak pressure of the whole foot as to the task height during the lifting task, the height from Knuckle to Shoulder was the least in the peak pressure. Also, as for the maximum force and the peak pressure of the whole foot as to the task angle during the lifting task, it could be seen that the more an angle increases, the stress influencing on a foot jumps. As for the maximum force and the peak pressure by foot region as to the task height in case of the lifting task, the height from Knuckle to Shoulder is indicated the smallest value in the maximum force and the peak pressure, thus there is necessary to attain the work design that considered this. Also, as for the maximum force by foot region as to the task angle in case of the lifting task, 0° tasking is indicated to be least, thus there is necessity to be attained the tasking design in a bid to prevent the existence of an angle. The results of this paper are thought to be helpful to the suitable work design, to the prevention of musculoskeletal disorders related to the lower limbs, and to the design of ergonomic safety shoes.
