The purpose of this study is to assess the reducing effect of work load on developed electro-motion scissors. To achieve this, we measured the pressure distribution, JSI(Job Strain Index) of electro-motion scissors and hand-operated scissor in objective assessment and surveyed the uncomfortable degree in subjective assessment. As a result, The peak of pressure in the electro-motion scissors was generally lower than the hand-operated scissors. JSI of the electro-motion scissors were remarkably lower than the hand-operated scissors. Also, the subjective uncomfortable degree showed that the uncomfortable point of electro-motion scissors were generally lower than the hand operated scissors.

As they do repeated work like carrying weighty material, it causes musculoskeletal disorder. In particular, in agricultural work, what is going to be repeated, is as digging hole, throwing soil that causes them to bend a physical burden. To solve such problems, we aims at attaching extra handle on agricultural instruments such as shovel, hook, sickle so that they can prevent injury and help efficacious job. To invent extra handle, we have selected the shovel as typical agricultural instrument and investigated which parts of body they use most in farming and what causes discomfort based on survey by twenty farmers. We produced primary prototypes based on those assessment and measured %MVC and cognitive uncomfortable degree (Five scores scale) by shovel work using general shovel people have been using and prototype we have invented. The representative subjects for %MVC were six in total: Left/right biceps, deltoid, and elector spinae and we measured subjective rate of discomfort in five parts of body: Neck, shoulder, arm, waist, and hand. In result of measurement, it demonstrated statistically highest %MVC in every part when they worked, with generally-used shovel more than when they used the shovel with extra handle. Especially, it showed twice of difference in elector spinae (With general shovel: 48.3; with newly invented shovel: 25.3). According to result of subjective uncomfortable degree, people have felt much more discomfort in every part except for hands when working with shovel. Particularly, it showed much highest in waist(With general shovel:4.5; with newly invented shovel: 3). By inventing extra handle for agricultural instrument, we expect that it is going to solve those problems, preventing musculoskeletal disorder and make agricultural job more efficacious.

Objectives: This study compared the characteristics of the work environment between agricultural and general workers and analyzed the effects of agricultural working characteristics on work-related health problems. Methods: The participants of this study were 2,347 agricultural workers and 48,042 general workers who were selected by applying standardized weights to the raw data of 50,538 respondents from the 6th Korean Working Condition Survey (KWCS). Variables applicable to both worker groups and related to exposure to hazardous risk factors in the working environment, working hours and intensity of work, health problems and work-related status, and satisfaction with the work environment were selected. Chi-square tests and independent sample t-tests were performed to evaluate the differences in the variables between the two groups. Multivariate logistic regression analysis was conducted to analyze the effects of work environment characteristics on work-related health problems. Results: Compared to general workers, agricultural workers were more exposed to hazardous environments, irregular work patterns such as working on Saturday/Sunday, and short repetitive tasks. They reported more work-related and general health problems, including back pain, upper extremity muscle pain, lower extremity muscle pain, and general fatigue. Agricultural workers showed lower satisfaction with their work environment than general workers. Factors affecting one or more work-related health problems included gender, working years, hazardous factors, irregular work pattern, working hours, and labor intensity. Conclusions: Our findings showed that agricultural workers were relatively more vulnerable to safety issues compared to other occupational groups. Therefore, it is necessary to establish standardized safety and health standards and strengthen systematic safety and health management policies and services for agriculture.
