  • This study was performed to determine the depression and its association with sleep quality, occupational stress and fatigue among small-scale manufacturing male workers. The self-administered questionnaires were given to 856 workers under 50 members of manufacturing industries during the period from April 1st to June 30th, 2010. As a results, the distribution of depression group(21 point and over at CES-D score) among all subjects were 44.3%, and it was positively correlated with occupational stress, fatigue and quality of sleep. With the analysis of covariance structure, occupational stress(KOSS) was more influential on the depression than quality of sleep and fatigue. It was found to have the inter-relational effects that the higher the occupational stress(KOSS) and fatigue(MFS), and the lower the quality of sleep, the higher the depression. Thus the effective strategy for depression reduction among workers requires the efforts to improve the work environment and job contents.

  • The effects and roles of social support and stressors (stressful life events and chronic strains) on psychosocial distress were examined in a model with data from a sample of the white-collar workers (N=416) in Korea. The findings of this study present that mean levels of psychosocial distress were higher in the female, youth, unmarried and divorced, and low economic status (monthly income). The analysis also shows that, as expected, stressful life and chronic strains as stressors are positively related to occurrence of psychosocial distress, and social support is negatively related to psychosocial distress. Further, the contribution of social support to predicting psychosocial distress is greater in magnitude than that of stressful events, chronic strains, and seciodemographic variables. There is no evidence that social support buffers the impacts of stressors on psychosocial distress, rather social support takes a role of mai or direct effects on psychosocial distress. Therefore, the strength of the social support is an important and meaningful strategy to prevent from stress and mental, physical illness.

  • Purpose: The purpose of the study >was to examine the prevalence of work-related musculoskeletal disorders(WMSDs) and to identify the relationship between work-related psychosocial and acculturative factors and WMSDs among Korean-Chinese workers living in Korea. Methods: A cross-sectional survey was conducted with 195 Korean-Chinese workers who have worked full-time for the past 6 months. A structured questionnaire, including measures for musculoskeletal symptoms, physical demand, work-related psychosocial(job demand, job control, interpersonal conflict), acculturative (acculturation strategy and acculturative stress), and personal factors, was used. Descriptive statistics and logistic regression analysis were conducted using the SPSS WIN 17.0. Results: The prevalence of WMSDs was 64.1%. In comparison to Korean workers, job demand of this group was lower while both interpersonal conflict and lack of job control were higher among them. Integration was the most commonly used acculturation strategy and mean scores of acculturative stress were below the median. Acculturative stress was positively correlated with integration and assimilation while negatively correlated with separation and marginalization. Interpersonal conflict and integration appeared to be related to WMSDs among male and female Korean-Chinese workers, respectively. Conclusion: The WMSD interventions need to be planned in consideration of different influences of work-related psychosocial and acculturative factors on WMSDs by gender.

  • Humans have a long history of asbestos use. There are reports from the Roman era, of asbestos victims among the slaves who worked in asbestos mines. The fact that asbestos can induce lung cancer and mesothelioma was verified epidemiologically in the 1960s. Asbestos related diseases are predominantly occupational in nature but can be caused by environmental exposure. Environmental mesothelioma is mainly associated with tremolite asbestos and this information comes from many countries including Turkey, Greece, Corsica, New Caledonia and Cyprus. In 1993, the first case of mesothelioma in Korea was reported in an asbestos textile worker. Recently, some asbestos disease victims who lived near an asbestos factory have their cases before the courts. A series of recent asbestos-related events in Korea, for example, the shocking revelation of asbestos containing talc in baby powders have caused the general public to become aware of the health risks of asbestos exposure. Asbestos related diseases are characterized by a long latency period, especially, mesothelioma which has no threshold of safety. Hence the best strategy for preventing asbestos related diseases is to decrease asbestos exposure levels to as low as possible.

  • Indoor air quality at classrooms is of special concern since students are susceptible and indoor air problems can be so subtle that it does not always produce easily recognizable health effects. The main objectives of the study were to investigate the time-activity pattern of school students, to determine the sources of poor indoor air quality in schools, and to demonstrate how indoor air quality in schools causes adverse health effects such as headache, upper airway irritation, fatigue, and lethargy. Recent articles ranging from 1987-2009 related to school indoor air quality were systematically reviewed. Building-associated health effects can increase student absences from school and degrade the performance of children while in school. The reduced ventilation rate was associated with a decreased ability to concentrate along with increased adverse health symptoms. There was an association between residential proximity to busy roads and a variety of adverse respiratory health outcomes in children. Consequently, the current findings suggest the need for control strategy for school indoor air pollutants with multidisciplinary approach methods because Korea has no other natural resources except manpower especially.

  • Activities to prevent industrial accidents can be divided into management of disaster risk factors of production facilities, disaster prevention systems and procedures, and human factors management. Human factor management is the last and most effective means to minimize disaster incidence and loss costs. The key strategy for this is safety and health education. However, formal or fictitious education is still being carried out in the industrial field. In addition, it is true that the application of practical use is insufficient due to the simple theoretical education based on knowledge transfer. In order to change the safety consciousness of employers and workers, we think that the paradigm of education should be changed from the traditional text and video-oriented lecture education method to experience-oriented education. The purpose of this study is to measure and analyze the effectiveness of safety education through education contents using VR(Virtual Reality) and AR(Augmented Reality) technology in keeping with the changing times of the 4th Industrial Revolution, And to suggest the direction of future safety and health education and content development trend.

  • Purpose: This study was conducted to analyze the characteristics of work-related musculoskeletal diseases (MSD) and the factors for approving MSD by the parts of the body. Methods: The analysis was done using the data which were drawn from the Industrial Accident Compensation Insurance that is operated by the Korea Worker's Compensation & Welfare Service. The data were composed of total cases related to the work-related diseases from 2006 to 2009. In addition, MSD data input by an investigator were collected. The factors associated with MSD were analyzed using ${\times}2$ and multiple logistic regression. Results: MSD approved cases have increased since 2006 and the proportion of the approved work-related MSD cases in the workers with work-related diseases in 2009 were 33.4%. Spinal approved cases were the highest percentage and upper and lower extremities cases gradually increased. The factors for approving upper extremity were found to be age, company size, type of industry, working duration, and in the case of spine to be company size and heavy lifting. Conclusion: Work-related MSD have increased and the factors that affected MSD by the parts of the body varied. Management strategy must be established to prevent MSD by the parts of the body.

  • Background: A detailed evaluation of the underground mine climate requires extensive measurements to be performed coupled to climatic modeling work. This can be labor-intensive and time-consuming, and consequently impractical for daily work comfort assessments. Therefore, a simple indicator like a heat stress index is needed to enable a quick, valid, and acceptable evaluation of underground climatic conditions on a regular basis. This can be explained by the unending quest to develop a "universal index," which has led to the proliferation of many proposed heat stress indices. Methods: The aim of this research study is to discuss the challenges in identifying and selecting an appropriate heat stress index for thermal planning and management purposes in underground mines. A method is proposed coupled to a defined strategy for selecting and recommending heat stress indices to be used in underground metal mines in the United States and worldwide based on a thermal comfort model. Results: The performance of current heat stress indices used in underground mines varies based on the climatic conditions and the level of activities. Therefore, carefully selecting or establishing an appropriate heat stress index is of paramount importance to ensure the safety, health, and increasing productivity of the underground workers. Conclusion: This method presents an important tool to assess and select the most appropriate index for certain climatic conditions to protect the underground workers from heat-related illnesses. Although complex, the method presents results that are easy to interpret and understand than any of the currently available evaluation methods.
