One of the objectives of any task design is to provide a safe and helpful workplace for the employees. The safety and health module may include means for confronting the design with safety and health regulations and standards as well as tools for obstacles and collisions detection (such as error models and simulators), Virtual Reality is a leading edge technology which has only very recently become available on platforms and at prices accessible to the majority of simulation engineers. The design of an automated manufacturing system is a complicated, multidisciplinary task that requires involvement of several specialists. In this paper, a design procedure that facilitates the safety and ergonomic considerations of an automated manufacturing system are described. The procedure consists of the following major steps. Data collection and analysis of the data, creation of a three-dimensional simulation model of the work environment, simulation for safety analysis and risk assessment, development of safety solutions, selection of the preferred solutions, implementation of the selected solutions, reporting, and training. When improving the safety of an existing system the three-dimensional simulation model helps the designer to perceive the work from operators point of view objectively and safely without the exposure to hazards of the actual system.

In order to provide basic data for the prevention of adverse effects of lead on health, we examined lead levels in the blood of 30 handicapped workers employed in manufacturing electronic components in Seoul from 2002 to 2008. The average lead level in the blood of all the subjects was $4.79{\pm}4.32{\mu}g/dL$ in females, $2.64{\pm}2.31{\mu}g/dL$ in males, and $3.88{\pm}3.75{\mu}g/dL$ in total. Lead levels examined in this study were significantly lower than other investigators study have reported. The average lead level from personal exposure of the subjects was $1.44{\pm}0.91mg/m^3$ in the workplace. The relation between blood lead levels and personal exposure was a simple linear regression; it's equation was "Lead level in blood = 6.04 - 1.92 lead level by personal exposure".

Objectives: This study was conducted in order to evaluate $PM_{2.5}$ concentrations at 20 offices connected to the manufacturing industry from the beginning of September to the end of November 2012. Methods: A total of 20 samples were collected from 20 office buildings. Each $PM_{2.5}$ sample was collected by a 37 mm PTFE filter attached to a Personal Environment Monitor. Results: The geometric mean concentrations of $PM_{2.5}$ in the offices was $23.47{\mu}g/m^3$, and the mean $PM_{2.5}$ concentrations measured in smoking offices were much higher than those of measured in non-smoking offices($24.83{\mu}g/m^3$ and $21.55{\mu}g/m^3$, respectively). $PM_{2.5}$ was revealed to be higher in small offices($39.52{\mu}g/m^3$) than in medium or large offices($22.69{\mu}g/m^3$ and $11.04{\mu}g/m^3$, respectively). The mean $PM_{2.5}$ concentration of offices located on the 1st floor was higher than that of those on the 2nd floor, and those of offices located in the workplace were higher than those out of the workplace. The multiple regression model showed that concentration of $PM_{2.5}$ was positively associated with the method of ventilation. Conclusions: Smoking, ventilation method, location, and inflow of outdoor particulate matter are the most important factors for office $PM_{2.5}$ concentrations.

Recently domestic manufacturing companies have been experiencing worsening profitability and stunted growth due to the long-term economic recession and the rapid rise of developing countries such as China and Southeast Asia. These difficulties force many companies to concentrate their core competencies on new value creation and innovation in order to gain momentum for new growth. Enterprise Resource Planning (ERP) has been considered as one of viable solutions. Among the various modules in ERP, shop floor control function in the production management module is rather limited. In order to overcome this problem, Manufacturing Execution System (MES) has been used as a subsystem which has a strong information gathering power and flexibility. Both systems interact closely with each other. In particular, ERP requires fast, accurate shop floor information at MES. This paper describes how to synchronize relevant information between ERP and MES with theory of constraints (TOC). The processing time information transmitted from the MES workplace is received at the ERP workplace. In the process, the received processing time is causing information distortion in ERP, when the information gathering standard of MES is different from the ERP information interpretation standard. The Drum-Buffer-Rope theory of TOC was applied to resolve this problem, therefore, information synchronization between both systems was made. As a precondition, the standard time of the upper ERP system was rearranged according to the capacity constraints resource. As a result, standard time restructuring has affected changes in labor costs. Standard labor costs have come close to actual ones, and information synchronization of MES transmission data has improved the reliability of standard product costs, such that it enabled various company-wide restructuring actions to be much more effective.

Background: Occupational accidents occur for a variety of reasons, such as unsafe behaviors of workers and insufficient safety equipment at the workplace, but there are also various economic and social factors that can impact working conditions and working environment. This study analyzed the relationship between changes in economic factors and the occurrence of occupational accidents in Korea. Methods: Multilinear regression analysis was used as the analysis model. The general to specific method was also used, which consecutively removes statistically insignificant variables from a general model that includes dependent variables and lagged variables of dependent variables. Results: The frequency of occupational accidents was found to have a statistically significant relationship to economic indicators. The monthly number of cases of occupational injury and disease and fatal occupational injuries were found to be closely related to manufacturing capacity utilization, differences in the production index in the services sector, and commencements of building construction. The increase in equipment investment indicators was found to reduce fatal occupational injuries. Conclusion: The results of this study may be used to develop occupational accident trends or leading indicators, which in turn can be used by organizations that manage and monitor occupational accidents toward taking administrative action designed to reduce occupational accidents. The results also imply that short-term and mid- to long-term economic and social changes that can impact workers, workplaces and working conditions, and workplace organizations must be taken into account if more effective government policies are to be established and implemented toward further prevention of occupational accidents.

Purpose: This study was constructed in order to examine factors that influence work-related musculoskeletal disease (WMSD) approvals and current status according to the company size. Method: This is a descriptive study that utilized Industrial Accident Compensation Claim Data. Workplaces with over 35,811 workers derived from the 2012 claim data, which comprised approximately 91.5%, were selected for this study. Then workplaces were divided into three groups according to the number of workers: less than 5, 5~299, and 300 and over. Results: Since 2008, the number of small sized workplaces has increased. The 2012 data showed that 32.5% of workers at small sized workplace had WMSD. However, workplaces with 5~299 workers showed WMSD approval rate of 60%. Of note most WMSD approved workers were employed by manufacturing and construction companies, regardless of the workplace size. Most of them were engaged in elementary tasks. The days of medical treatment at OPD and IPD were most prevalent among workers at the largest workplaces. Conclusions: It is certain from this study that WMSD has been polarized by the company size. More policy attention should be paid to the WMSD status of workers at small sized workplaces which usually do not have their own health office.
