The purpose of this study is to grasp foreign worker's industrial safety and health state, which find out the improvement to secure the basic safety net for foreign workers. We have investigated 2,050 workers through direct interviews during the period from April 12, 2010 to May 31, 2010. And the result of analysis, foreign worker's daily average working time is 10.6 hours(40.8% workers in total work 10~12 hours), the extent of exposure to harmful and dangerous working environment is 'the position which cause pain in neck, waist, hands, shoulders, legs'(69.3%), 'repetitive hands and arms movement'(66.1%). It showed 'experience of accident damage or disease related work'(27.3%), 'never apply for industrial accident compensation' is revealed high at 73%. As a result of completing a safety health education for a year, it showed 'never educated'(40.2%), 'the institute that foreign workers have used for help and advice is the foreign worker's support center'(61.9%) Thus, hiring foreign workers in the company are small in site, the environment is too harmful and dangerous. In addition, no safety and health managers, legally blind spot located in the health and safety, because it is an urgent meet for these measures to improve.

In industrial field, there are several operations where a horizontal unidirectional airflow is used to control airborne contaminants. When a worker is immersed in a uniform freestream, a recirculating airflow can be created downstream of the worker by the phenomenon of boundary layer seperation. If the contaminant source and the breathing zone are within this near-wake region, high exposure may occur. The investigation for the effect of contaminant source location on worker exposure was performed by using CFD(Computational Fluid Dynamics). The airflow field was numerically calculated by assuming a steady flow and using the standard $k-{\varepsilon}$ turbulence model. As the results were compared with experimental data, the applicability of CFD was successfully verified. Subsequently, the breathing zone concentrations of the worker were predicted and compared with experimental data. The effects of contaminant density and turbulence intensity of freestream on worker exposure were evaluated.

This paper proposes a maintenance method to integrate worker's safety concerns into the process activities of the manufacturing system and it is to be considered as a part of the scope of maintenance engineering. The proposed method incorporates worker's health and safety considerations into maintenance engineering in each of the manufacturing process using reliability analysis. It can help to make a better planning and implementation of maintenance activities for the manufacturing system.

For Web server implementations, there are 4 main schemes: process-per-request (PPR), thread-per-request (TPR), worker thread pool (WTP), and worker thread pool with buffers (WTPB). This paper compares performance of the schemes in response time point of view. WTPB shows the best performance. The appropriate number of worker threads for WTPB depends on the request service time. For short requests, the number can be very small. But for longer requests, it is about 1/6 of the number of simultaneous connections.

Objective: This research provides a guideline for working area design in the electronic industry, considering gender differences of physical characteristics. Background: Co-work in the electronic industry requires workers of various physical properties to work cohesively in the conveyor line for mass production. This stresses the need for a worker-centered design of the workplace convenient for all the workers. Method: In this research, the $6^{th}$ Size Korea (National Anthropometric Survey in Korea) report is referred to obtain the design measurements according to age and gender varieties. This information is used to provide the working area guideline concerning conveyor line workers of both genders aged 20 to 40. Results: Physical properties of workers and workplace design principles were obtained for application in the assembly, inspection, and material handling process in the electronic industry. Conclusion: Applying ergonomic design principles can provide safe and comfortable workplace for both genders. Application: This research can be fundamentally used in designing worker-centered workplaces.

Home care, known also as domiciliary care, is part of the community care service that is a responsibility of the local government authorities in the UK as well as many other countries around the world. The aim is to provide the care and support needed to assist people, particularly older people, people with physical or learning disabilities and people who need assistance due to illness to live as independently as possible in their own homes. It is performed primarily by care workers visiting clients' homes where they provide help with daily activities. This paper is concerned with the dispatching of care workers to clients in an efficient manner. The optimized routine for each care worker determines a schedule to achieve the minimum total cost (in terms of distance traveled) without violating the capacity and time window constraints. A collaborative population-based meta-heuristic called Particle Swarm Optimization (PSO) is applied to solve the problem. A particle is defined as a multi-dimensional point in space which represents the corresponding schedule for care workers and their clients. Each dimension of a particle represents a care activity and the corresponding, allocated care worker. The continuous position value of each dimension determines the care worker to be assigned and also the assignment priority. A heuristic assignment scheme is specially designed to transform the continuous position value to the discrete job schedule. This job schedule represents the potential feasible solution to the problem. The Earliest Start Time Priority with Minimum Distance Assignment (ESTPMDA) technique is developed for generating an initial solution which guides the search direction of the particle. Local improvement procedures (LIP), insertion and swap, are embedded in the PSO algorithm in order to further improve the quality of the solution. The proposed methodology is implemented, tested, and compared with existing solutions for some 'real' problem instances.

Purpose: This study aimed to investigate the effect of an intensive rehabilitation program on the pain, range of motion (ROM), muscle strength, function, quality of life (QoL), and depression of patients with traumatic rotator cuff injury caused by an industrial accident. Methods: Seventeen patients with traumatic rotator cuff injury caused by an industrial accident participated in this study. The 12-week treatment included 30 min of manual therapy and 30 min of exercise therapy twice a day, five times a week. The outcomes were measured for evaluating the pain, ROM, muscle strength, function, QoL, and depression before the commencement of the program and after 4, 8, and 12 weeks. Results: According to the time of applying the intensive rehabilitation program, the pain (p<0.01), ROM (p<0.01), muscle strength (p<0.01), function (p<0.01), and depression (p<0.05) significantly improved with time. However, QoL was not statistically significant. Conclusion: This study confirmed the excellent effect of an intensive rehabilitation program on the pain, ROM, muscle strength, function, and depression of patients with traumatic rotator cuff injury caused by an industrial accident. However, this study was limited by the absence of a control group. This pilot study highlights the need for more extensive research with a larger sample.

The purpose of this study was to identify K.A.P. of industrial workers on health management. The study was conducted Dec 5, 1992 to March 10, 1993. The results were as follows : 1. The total Score of K.A.P. of industrial worker on the Knowledge of industrial health management was 2.52, the Attitude score was 42, the Practice score 2, 62. 2. The office workers' score on K.A.P.(T=-2. 11, P=.038) Attitude score(T=-2.03, P=.045) were higher than that of productive workers' 3. The K.A.P. score of married worker was higher than that of single workers, and showed significant differences statistically. 4. There are significant statistical differences in the Attitude score of workers according to age(F=2.26, F=.0304). 5. There were statistically significant differences among total Scores of K.A.P. (F=3.1141, P=.0498). Practice score(F=8.4421, P=.0004), Knowledge Score (F=3.5833, P=.0323). Performed 84.7%. 6. The relationship between industrial worker's health level score and industrial health status had reverse relationship(R=-.7689. P<.001) Therefore the companies that performed better health management attained a higher health level.
