Generally, a fixed type guide-bush system is installed during machining miniature work-pieces with high precision in the multi-task CNC lathe. But a conventional guide-bush system does not provide a constant clamping force under the condition of varying work-piece diameters. It is important to maintain a constant clamping force for guaranteeing machining precision. This paper proposes a new guide-bush system with a pneumatic clamping device for the CNC Swiss-turn lathe to keep constant clamping force with changes in work-piece diameters. Through performance tests, new clamping system developed in the study showed better machining precision at the cost of a small increase in the temperature of the system than conventional systems due to an increase in the frictional heat and a change in the heat transfer route.

Background: Household waste collectors (HWCs) are exposed to hazardous conditions. This study investigates the patterns of workplace injuries and work-related illnesses of HWCs. Methods: This study uses cases of workplace injuries and work-related illnesses of HWCs that occurred between 2010 and 2011. We analyzed 325 cases of injuries and 36 cases of illnesses according to the workers' age, length of employment, size of workplace, injured part of body, day and month of injury, type of accident, agency of accident, and collection process. Results: There were significant differences in the effect of workers' length of employment, injured part of body, type of accident, agency of accident, and collection process. Results show that most injuries occur in workers in their 50s and older. This study also shows that 51.4% of injuries occur at businesses with 49 employees or fewer. Injuries to waste collectors happen most often when workers are electrocuted after slipping on the ground. The second most prevalent form of injury is falling, which usually happens when workers hang from the rear of the truck during transportation or otherwise slip and fall from the truck. Work-related illnesses amongst waste collectors are mostly musculoskeletal conditions due to damaging postures. Conclusion: These findings will be instructive in devising policies and guidelines for preventing workplace injuries and work-related illnesses of HWCs.

A questionnaire survey of farmers engaged in actual farming was conducted to investigate the farmers' actual wearing conditions and preferences for agricultural workwear to develop workwear that is suitable for improved agricultural work efficiency. We extracted basic data necessary for the development of agricultural workwear. Analysis of the photographs taken showed differences in the shoes and gloves worn depending on the type of work. The percentages of men and women were equal among the agricultural workers. The age of the agricultural workers was analyzed and the results showed a higher percentage of those over 50 years old, indicating that the age of the agricultural workers was higher than in other industries. It was found that the waist, knees, and elbows of the workers were pulled during work, and analysis showed that the symptoms resulting from clothing pulling were more severe when the wearing dimensions were larger. It was recognized that the important aspects of workwear are those related to work, such as functionality, activity, and work efficiency. In addition to workwear, the most commonly worn auxiliary equipment was gloves, and other items included hats, armbands, work shoes, boots, seat chairs, and masks. When developing rural workwear, it is necessary to consider the fit, type of work, and materials of the workwear. Future research should focus on materials that can improve the functionality of workwear and pattern development that reflects physical and movement characteristics.

We studied the actual condition of work environment and work morale according to the type of employment of service workers by using the raw data of the Fourth Work Environment Survey (2014) conducted by the Institute of Occupational Safety and Health. In this study, the condition of work environment were composed of work posture, emotional labor, and work autonomy. Also, dimensions related to work morale were composed of competence, job satisfaction, social support, and job stress. In addition, the employment was classified into three types of regular workers, temporary workers, and daily workers. The results showed that temporary and daily workers were more likely to work in a less favorable environment than regular workers, and there was a close correlation between work environment and work morale. Based on this study, it is possible to know about the actual situation and problems of the service workers, and it is hoped that company can search for measures to increase the working environment and work morale of the workers in order to provide better service.

Work-related low back pain is one of the major factors that cause the loss of working power especially in actively working age, therefore controlling the work-related low back pain is one of the major issues in the field of industrial safety and health. This study was performed for detecting the risk factors and proposing the efficient control program of the work-related low back pain. The subjects were male workers employed at the manufacturing industry in Pusan with longer than 6 months' working duration. The data was collected by self-reported questionnaire and interview from May 1 to October 31,1992. The contents of questionnaire were as follows:. the experience of low back pain within the recent one month, general characteristics(age, marital status, education level, religion, regular exercise), physical characteristics(height, weight), employment status(working duration, daily working hours, rest during work, satis(action fur the job), type of work and working environments(posture, forward bending, lifting and movement, satisfaction for table and chair). The result was analyzed for 608 entire respondents by case-control comparative method. The number of cases was 152 with a history of work-related low back pain, so the relative frequency of self-reported work-related low back pain was 25.0%, and the number of controls was 344 without any history of low back pain. As a result, two characteristics of the employment status(working duration, satisfaction fur the job) and all characteristics of type of work and working environments showed a statistical significance between the case and control groups(p<0.01). The Oddb ratios of these variables for Work-related low back pain were calculated. They were 7.88 for the satisfaction fur chair, 7.86 for lifting and movement,3.31 for satisfaction for table, and 2.22 fur bending forward(p<0.01). And for the multivariate logistic regression analysis confirmed that unsatisfaction for table was independent risk factor for Work-related low back pain. In summary, though this study was based upon the self-reported questionnaire and the subjective complaints, the satisfaction for chair, lifting and movement, satisfaction for table, and bending forward concerned with the type of work and working environments were considered as the main factors causing the work-related low back pain, and the work-related low back pain may be preventable by the ergonomic control of these factors.
