This study was intended to help workplaces set up an occupational health & safety management system by investigating the certification of the system and by conducting a questionnaire to survey the necessity, purpose, effect and promotion of the system. The occupational health & safety management systems generally adopted in Korea are OHSAS 18001 and K-OHSMS 18001, which are the PDCA model, such like the quality and environment management system. Because these standards have a compatibility with other management systems, individual or integral certification is available. A telephone questionnaire was conducted with 30 workplaces in Kyeonggi Province and Incheon Metropolitan City, which have been certified for the occupational health & safety management systems (OHSAS 18001, KOSHA 2000, and/or K -OHSMS 18001). About 92 percent of them were large-sized workplaces with over 500 employees. For the question on the necessity of the system, most of the respondent answered very necessary. The purposes of the certification were to control the risks in safety and health, to have a systematic approach for accident prevention and sustainable improvement, and to comply with a range of regulations voluntarily, in that order. Most of the answers to the question on the effect of the system were prevention of accident. For the question on the promotion of the system, the most prominent answer was reduction in the workers compensation rate.

Objectives: Quality of Working Life(QWL) is a set of employee's physical, mental conditions which are perceived at their work. Most employees and managers are concerned about the quality of working life as a strategy for improving organizational effectiveness. The purpose of this study is to investigate the relationship between QWL and organizational effectiveness of employees at the general hospital. Methods : Data were collected by self-administered questionnaires at the general hospital in Kyunggi-Do. Survey was conducted to 675 workers. QWL was measured by using 5 items from the scale developed by Walton(1973). Organizational effectiveness was measured by measuring organizational commitment, intention of job-shift, and job satisfaction. Results: The recognitions to each component of QWL were significantly different by socio-demographic characteristics such as sex, age, education levels and working duration. Also, QWL were significantly different by types of organizational culture. Multiple regression analysis and multiple logistic regression analysis were applied to find the relationship of QWL and organizational effectiveness. As a result, job-pride, compensation, working condition, human relationship and development showed significant relationship with organizational effectiveness. Conclusions: These results show that QWL is significantly related to organizational effectiveness. So we expect that this result will be used as basic informations for management and motivation of employees at the general hospital.

Objectives: The purpose of this study was to identify the health promotion activities of the elderly Korean aged 65 or older and to examine the related factors associated with the health promotion activities. Methods: Data were obtained from 2008 Social Statistics Survey of Korea National Statistical Office of 6,207 people aged 65 or older. We measured the socio-demographic characteristics, physical health status, social health status, and health promotion activities. Statistical analyses were employed through the $X^2$-test and Odds ratio using Logit Model. Results: In our study, health promotion activity practice rates were varied among the socio-demographic characteristics, physical and social health status. Our findings also support that better socio-demographic and physical health status explain the higher practice rates of health promotion activities. In addition, the higher social health status was associated with better practice rates of health promotion activities. Conclusion: We found that the health promotion activities of the elderly could be encouraged by better socio-demographic status and physical and social health status. To better accomplish the health promotion for the elderly in our community, policy-makers should need careful political deliberation for executing health promotion services considering the distinctions of programme and target groups.

Objectives: This study aimed to characterize the nanoparticles produced by welding and grinding processes. Methods: The number concentrations of particles were mapped to determine the distribution of welding fumes in a workplace atmosphere using a hand-held condensation particle counter. An electrical low-pressure impactor was used for measuring the number concentration and particle size distribution. Results: High number concentrations were found around arc cutting and welding (grinding) processes. In the worker's breathing zone, the mean number concentration was 655,000 particles/cm3 and the count median diameter (CMD) was 84 nm with several multi peak distributions (~20, 70, 300 nm). However, at a distance of 3 m from the welding position, the number concentration decreased to 153,000 particles/cm3 with a 70 nm single peak size distribution. During a grinding process, peaks with high concentrations of nanoparticles were temporarily observed. The mean number concentration was 1,520,000 particles/cm3, and the CMD was 30 nm. Nanoparticles (<100 nm) made up 58% and 92% of the aerosols produced by welding and grinding processes, respectively.

Objective: The objective of this study was to estimate the numbers of employees occupationally exposed to noise according to their industry and size. Methods: A Delphi panel consisting of 15 occupational health experts estimated the exposure prevalence of noise in workplace. Data on Industrial Accident Compensation Insurance provided from Occupational Safety and Health Research Institute were combined to produce the exposure population. Results: In Korea, 16.0% of employees, 2,539,890 out of 15,838,926, was estimated to exposed to noise occupationally. The rate was 32.7% and 10.3% in manufacturing sector and non-manufacturing sector, respectively. The highest rate, 52.5%, was found in manufacturing industries of wood and of products of wood and cork(except furniture) and of other transport equipment. Sorted by their size of business, the rate was higher as the number of employee was larger in manufacturing sector.

Purpose: This study examined the most effective exercise while performing shoulder abduction below ninety degrees. Methods: Thirty two healthy individuals (17 males, 15 females) participated and performed four exercises, 1) Posterior fly, 2) Prone row, 3) Modified prone cobra, and 4) External rotation in the prone position. Surface electromyography (sEMG) was used to measure the electrical activities for the lower, middle and upper fiber of trapezius and serratus anterior. Results: A significant difference in the muscle activities of the upper/middle/lower trapezius and serratus anterior was observed among the three different positions in terms of the PF (posterior fly), PR (prone row), and MPC (modified prone cobra) (p<0.05). In post-hoc analysis, the activities of the lower and upper trapezius were significantly higher than those of the upper trapezius and serratus anterior (p<0.05). In addition, in ERP (external rotation in prone), there was a significant difference in each activity of the muscles. Post-hoc results indicated that the upper trapezius showed greater EMG activity than the other three muscles. Conclusion: External rotation in the prone position revealed the highest activation of the lower trapezius compared to upper trapezius muscle activity. This may be particularly useful in isolating the lower trapezius in cases where excessive scapular elevation is noted. Therefore, the most effective lower trapezius exercise should be performed below ninety degrees of shoulder abduction.
