Efforts to identify jobs or tasks having known risk factors for work-related musculoskeletal disorder can provide the groundwork for changes aimed at risk reduction. An effective identification method is the ergonomic job hazard analysis which breaks a job into its various elements or actions, describes them, measures and quantifies the ergonomics risk factors. Some analytical methods including OWAS, RULA, REBA, and NLE have been used as tools in quantifying the risk factors. But these traditional methods using worksheet or paper are difficult to explain to participants for performing the job hazard analysis in the field, and take a long time. We develop some software tools to implement the analytical methods using EXCEL programs or computer program. These tools developed in this study are faster and easier to perform the ergonomic job analysis than the traditional methods using worksheet.

Job hazard analyses were conducted to assess exposure to musculoskeletal disorder (MSD) risk factors in seven workers of three dry-cleaning establishments. In accordance with the Washington State Ergonomics Rule, the analyses were performed in two separate steps: (1) observation and checklist approaches were made to identify a "caution zone job" in the seven workers' pressing operations across the three shops; and (2) detailed posture and motion analyses were undertaken to determine a "MSD hazard" in one worker's operation using a video technique. One "caution zone job" was identified and it was the pressing operation job in which five physical risk factors were found in the pressing operations. The detailed analyses confirmed that one "MSD hazard", i.e., awkward posture in shoulders, was prevalent in the pressing operations of the three dry-cleaning facilities. It would be desirable to reduce MSD risk factors including awkward shoulder posture in the dry-cleaning industry.

This study identified hazard exposures, health problems, and job satisfaction among elderly agricultural workers. A total of 1,340 agricultural workers (1,079 males and 261 females) were extracted from the 6^th Korean Working Conditions Survey data. Three age groups (A: 40s or below, B: 50s, and C: 60s or above) were statistically compared in hazard exposures, health problems, and job satisfaction. Elderly agricultural workers (60s or above) had significantly more exposure to ergonomic hazards, severe health problems, and lower job satisfaction than young agricultural workers. The study findings may help understand the characteristics of hazard exposures, health problems, and job satisfaction of elderly agricultural workers and will be useful for improving these conditions.

This study was planned to investigate the effect of the exposure to hazard factors on work environment satisfaction. Existing researches about job satisfaction have focused on the general working conditions, such as working hours, wage, human relationship, job task and so on. Korean Working Conditions Survey was used for this study because that relevant questions were included. The effect of the exposure to hazard factors on work environment satisfaction may be produced by hierarchical regression analysis because of comparison with existing model for work environment satisfaction. The exposure to hazards factors were statistically significant effect on work environment satisfaction after adjusting other confounding variables, such as gender, age, educational level, job security, work hour, work load, work autonomy, social support, etc. This study has some limitation because that KWCS was cross sectional survey. Some researches about the causal effect and its mechanism may be suggested as future study.

항공산업의 발전에도 불구하고 조종사의 인적오류에 의한 항공기 사고는 지속해서 발생하고 있다. 인적오류에 의한 항공기 사고의 원인은 비행안전을 저해하는 위해(hazard) 요인을 사전에 제거하지 못해 사고로 이어지는 것이다. 본 연구는 국내 항공사에 근무하는 운항승무원과 일반항공 (general aviation)의 조종사를 대상으로, 비행안전을 위협하는 여러 가지 위해 요인 중에서 조종사에게 심리적, 신체적으로 영향을 미치는 직무스트레스와 피로, 불안감이 안전행동에는 어떠한 영향을 미치는지 살펴보았다. 아울러 직무스트레스와 안전행동의 간에 안전문화의 매개효과를 확인하기 위한 실증분석을 실시하였다. 연구 결과에 의하면 직무스트레스는 조종사의 안전행동에 직접적인 영향을 줄 뿐만이 아니라 안전분위기, 보고문화와 같은 항공사의 안전문화에도 영향을 미친다는 것이다. 이러한 조종사의 직무스트레스와 안전문화, 안전행동간의 상관관계를 통해 안전관리시스템의 성과를 제고하고자 한다.

Objectives: This study was designed to investigate the current status of the association of job-related information such as employment status, workplace environment, and hazard material exposures with health examination outcomes. Methods: The study used data from KNHANES 2007-2009 representing the three years of 2007-2009, which was conducted annually using a rolling sampling design that involved a complex, stratified, multistage, probability-cluster survey of a representative sample of the non-institutionalized civilian population in Korea. The final analytical sample consisted of 17,240 participants. Information on age, education, smoking history and alcohol intake was collected during the health interview. Job related information consisted of employment status, workplace environment, and hazardous material exposure. The selected indices of health examination were blood pressure, fasting glucose, blood cholesterol, HDL, SGOT, SGPT, and BUN. Results: In multiple logistic regression analysis using hypertension and pre-hypertension as dependent variables and job related categories as independent variables after covariate adjustments, the odds of hypertension and pre-hypertension were significantly lower in those with responsibility and power in their job activities. Interestingly, low odds for hypertension were observed among those who reported that their jobs were fast-paced. Conclusions: This study confirmed that some job-related categories in employment status, workplace environment, and hazardous material exposure had an association with health outcome status. It is worthwhile to comment that high responsibility and power in job activities were revealed as one of the important favorable factors to improve health condition of workers.

Each year research institutions such as the Korea Employment Information Service(KEIS), a government institution established for the advancement of employment support services, and Job Korea, a popular Korean job website, announce first job waiting times after college graduation. This provides useful information understand and resolve youth unemployment problems. However, previous reports deal with the time as a completely observed one and are not appropriate. This paper proposes a new study on first job waiting times after college graduation set to 4 months prior to graduation. In Korea, most college students hunt for jobs before college graduation in addition, the full-fledged job markets also open before graduation. In this case the exact waiting time of college graduates can be right-censored. We apply a Cox proportional hazards model to evaluate the associations between first job waiting times and risk factors. A real example is based on the 2008 Graduates Occupational Mobility Survey(GOMS).

Background: In this study, the measurement of job stress of electric overhead traveling crane operators and quantification of the effects of operator and workplace characteristics on job stress were assessed. Methods: Job stress was measured on five subscales: employee empowerment, role overload, role ambiguity, rule violation, and job hazard. The characteristics of the operators that were studied were age, experience, body weight, and body height. The workplace characteristics considered were hours of exposure, cabin type, cabin feature, and crane height. The proposed methodology included administration of a questionnaire survey to 76 electric overhead traveling crane operators followed by analysis using analysis of variance and a classification and regression tree. Results: The key findings were: (1) the five subscales can be used to measure job stress; (2) employee empowerment was the most significant factor followed by the role overload; (3) workplace characteristics contributed more towards job stress than operator's characteristics; and (4) of the workplace characteristics, crane height was the major contributor. Conclusion: The issues related to crane height and cabin feature can be fixed by providing engineering or foolproof solutions than relying on interventions related to the demographic factors.
