Recently, work-related musculoskeletal disorders(WMSDs) is one of the major issues in the shipbuilding industry. The number of injured workers has rapidly increased and demands for workers compensation, improvement of work condition and environment to prevent WMSDs become larger. To protect and reduce WMSDs in the shipbuilding industry, simulation technique which showed it's ability of increasing the manufacturing productivity will be applied, because simulation technique has the evaluation ability for a worker's danger level of production process by human activity analysis. In our research, we modeled worker's attitude and simulated worker's action. We evaluated the caution level, compared and analyzed the difference point of digital human which made on computer and actual worker's attitude to check feasibility of human modeling and simulation in the shipbuilding industry.

This study was aimed at rating the existing work environment noise components and alternatives in point of worker's view. To answer the purpose, AHP(Analytic Hierarchy Process) method is adopted in this research. Based on the AHP method, this research abstracts a mathematically rigorous noise components and alternative's weights and proven process for priority and decision-making. By reconstructing complex hearing conservation programs to a series of pair-wise comparisons, and then synthesizing the results, this study not only helps establishments of noise countermeasure, but also provides a clear rationale for noise alternatives. The result of this study is summarized as follows; 1) Job satisfaction index and noise identification index are 63, 56 respectively. 2) Noise level(15.7%), frequency(14.1%) and directivity(13.6%) are main reasons in worker's ground. 3) There are some difference between the estimation of worker's identification and that of work sites. 4) Low noise machine(14.7%), enclosure(13.2%) and shielding(9.6%) are chosen for noise protection method by workers. 5) Noise environment improvement should be focused on noise source rather than personal protection. 6) By the AHP method, noise source countermeasure have a key role at work environments.

Background : There have been many studies and efforts about quality management in health services, but there were not founded quality assessment on social services. This study was designed for understood level of quality on social service, identified for correlation factors of quality assessment on social services in general and teaching hospitals in Korea. Methods : The subjects of this survey were 80 leaders of social service units. The survey data from each subjects were measured to evaluate level of quality that service provider perceived of sample hospitals. Social worker's attitude of quality assurance activities, perception of quality assurance system in that hospitals were measured. Under the method of one-way ANOVA, t-test and correlation, associated factors of quality assessment in social work service was analyzed. Results : The major findings were as following ; First, the level of quality perceived showed less score, especially the lowest was the score of quality of outcome. Second, social worker's attitude of quality assurance activities showed high score, but quality assurance system of hospitals showed less score. Third, the level of quality assurance system of hospitals, social worker's attitudes of quality assurance activities. Conclusion : The quality of social work service correlated positive hospitals's quality assurance system, social worker's attitudes of quality assurance activities. Therefore, to assure the proper level of quality, qualified for hospitals system of quality assurance, and needed to a educational program for enhanced social workers's attitudes in quality assurance activities.
This study attempts to explain how the social-worker empowerment in the field of social work relates to social-work self-efficacy and whether or not the transactional leadership of the leader moderates the relationship between these two variables. Data from 390 social workers working with public and private sector agencies in Seoul were collected. For the questionnaire and analysis, this research uses the Social Worker Empowerment, Social Work Self-Efficacy, and Transactional Leadership scales. This research utilizes a wide range of statistical analyses, such as descriptive analysis, Pearson's correlation, reliability analysis, factor analysis, multiple regression, and general linear modeling. The calculations employed the use of SPSS/PC+ 12.0. This research indicates, among other things, that social workers with a high level of social worker empowerment and transactional leadership of the leader show a tendency toward higher social work self-efficacy and that the leader's transactional leadership level plays a moderating function in the relationship between social-worker empowerment and transactional leadership of the leader. In conclusion, a social worker with a low level of leader's transactional leadership shows a relatively greater tendency toward social work self-efficacy when compared to a social worker having a high level of leader's transactional leadership. Social workers and social-work organizations seeking professional practice can benefit from these findings on the relationship between professional behavior and social work self-efficacy with perceived transactional leadership about a team leader as a moderator.
Generally working environment and worker's health status of small scale industries (SSI) which employ less than 50 workers are known to be poorer than those of large scale industries(LSI) which employ more than 500 workers. However, according to the analysis of occupational injuries in Korea, prevalence rate of occupational injuries of SSI was 3.1 times as high as LSI. But there was no difference in prevalence rate of occupational disease and werkers with suspected occupational disease(D1) between SSI and LSI. To confirm these two different facts, we surveyed working environment and worker's health status of SSI and LSI in Kyeungin industrial complex. Workers in SSI were 10,878 and workers in LSI were 8,291 and number of hazardous agents in SSI were 3,554 and those of LSI were 1,916. We found following results. First, proportion of male workers and workers who were less than 30 yens old and more than 50 yens old was higher in SSI compared to LSI. Second, worker in SSI had more liver disease, viral hepatitis, and pneumoconiosis than in LSI, and there were more worker with suspected occupational disease, general disease, and worker needed close observation in SSI. But these effects had not statistical significance under the condition controlled by age and sex with logistic regression. Third, the numbers measured for specific chemicals, organic solvents, and heavy metals in SSI was more than in LSI. However there was on difference in the excess rate of each hazardous agent between SSI and LSI. As the above results workers' health status in SSI was poorer than in LSI, but these results were mainly due to the population structure difference. Although there were some limitation of this study and problems of sensitivity and validity for periodic health examination and working environment evaluation method, the concept that working environment and worker's health status in SSI should be reviewed. In future the study that will reveal the real weak point of SSI should be performed.
Korea's elevator industry is one of the world's eighth-largest industrial sectors and the third largest in the world by new installations. This year, the number of elevators has exceeded 700,000, and the number of new installations is 30,000-40,000 every year. However, the news of elevator-related accidents is reported continuously through the media and the accident rate is not decreasing. In particular, among the recent accidents related to elevators, accidents related to elevator workers are increasing, causing social problems. This year, the National Assembly's Environmental Labor Relations Commission's National Auditors lost five lives a year and 12 elevator workers were killed in fall and stenosis accidents during the installation, maintenance and replacement of the elevators for about two years since 2018. It took place to adopt the representatives of four domestic elevator companies as witnesses. An elevator worker is a collective term for workers involved in the design, manufacturing, installation, replacement, maintenance, inspection, management, and supervision related to the elevator industry, and the related accidents are called elevator worker accidents. Analysis of elevator-related accidents in the past has shown that the fault of the user accounted for 70% of the total, and the fault of the worker accounted for about 2.5%, and the accident occurred to the user or the user due to carelessness of the worker during the lift-related work. Currently, elevator-related accidents are reported by the Korea Elevator Safety Agency under Article 48 of the Elevator Safety Management Act under the Ministry of Interior and Safety. If deemed necessary for the prevention and prevention of recurrence of an elevator accident, the cause and condition of the elevator accident may be investigated. However, the current draft law is limited only to elevators after installation inspection, and is separated from the Ministry of Employment and Labor's data on accidents occurring in the manufacturing and installation stages related to the elevator industry. This study analyzes the recent safety accidents of elevator workers and prepares safety measures to prevent them through the risk analysis, and also draws out the problems and improvements of the current elevator worker accident investigation to find the elevator worker accident rate that is on the increase trend.

Purpose: This study was conducted to understand the situation of general hospital worker's health management and health promotion. Methods: To investigate the current situation of health management in the hospital, structured questionnaires were sent to 122 occupational health providers by post. About 79% hospitals returned questionnaires. The data were analyzed using descriptive analysis, ${\chi}^2$-test by SPSS 12.0 program. Results: A quarter hospitals responded set up separated health care office for workers, 87.5% provided health educations, and 56.5% operated health promotion projects. In the contents of health promotion program embraced both health behavior practice and disease prevention, musculoskeletal disease control, infection control, smoking cessation, and exercise program were most commonly provided to the workers in order. Occupational health care provider chose the item such as budget limitation, manager's apathy, lack of employee's participation, cooperation provider, and so on as the reason of difficulty to run health promotion program in the hospital setting. Conclusion: Hospital managers need to construct infra to manage and promote worker's health. For example, establishing Industrial safety and health committee in hospital and arranging nurses who being fully responsible to worker's health. And occupational health care provider should advertise health promotion projects both managers and workers actively.
This study was performed to evaluate the worker exposure to asbestos fibers in automobile repair shop and brake lining store from August 11 to October 21, 1988. In addition, the exposure of general population near the brake lining store was also evaluated. Results of this study were as follows. 1. Worker exposure level to asbestos fibers in automobile repair shop was 0.1 fibers/cc, well below the Korean standard of 2 fibers/cc, and a half of the U.S. standard of 0.2 fibers/cc. 2. Average worker exposure level to asbestos fibers in brake lining store was 0.35 fibers/cc, which was within the Korean standard of 2 fibers/cc, but exceeded the U.S. standard of 0.2 fibers/cc. 3. Worker exposure levels during the removal of brake dust with the compressed air blowing and the dry brushing were approximately 4 fibers/cc and 0.2 fibers/cc, respectively. During grinding of brake linings with sand paper, asbestos exposure level was 0.3 fibers/cc. 4. Ambient asbestos concentrations outside the brake lining store were 0.1 fibers/cc at the distance of 3-4 m, and 0.01 fibers/cc at the distance of 30 m.
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.
