Supplementary Material - Background
Long working hours have been associated with adverse physical and mental health outcomes; however, evidence regarding their relationship with satisfaction with work environment remains limited, particularly when long working hours are defined using a specific daily threshold. This study examined the association between working ≥10 hours per day and satisfaction with work environment among Korean wage workers, focusing on the cumulative number of such workdays per month.
Methods
This cross-sectional study analyzed data from the 7th Korean Working Conditions Survey. A total of 24,269 wage workers aged ≥18 years were included after excluding self-employed workers, unpaid family workers, shift workers, and respondents with missing data. Working ≥10 hours per day was categorized as 0, 1–9, and ≥10 days per month. Satisfaction with work environment was categorized as satisfied or dissatisfied. Multiple logistic regression analyses were conducted to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for dissatisfaction with work environment according to the number of long working days, adjusting for demographic and occupational characteristics.
Results
Compared with workers who did not work ≥10 hours per day, those who worked 1–9 days and ≥10 days per month showed progressively higher levels of dissatisfaction with work environment. After adjustment for demographic and occupational factors, the odds of dissatisfaction with work environment were significantly higher among workers who worked ≥10 hours per day for 1–9 days per month (OR: 1.380; 95% CI: 1.145–1.665) and ≥10 days per month (OR: 2.106; 95% CI: 1.627–2.725), demonstrating a dose–response relationship.
Conclusions
Among the analytic sample of Korean wage workers included in this study, working ≥10 hours per day was associated with greater dissatisfaction with work environment, with a dose–response pattern according to the number of long working days per month. - 한국 임금 근로자의 하루 10시간 이상 근무 일수와 근무환경 만족도와의 연관성
목적
장시간 근무는 근로자의 신체적·정신적 건강에 부정적인 영향을 미치는 주요 직업적 요인으로 알려져 있으나, ‘하루 10시간 이상 근무’라는 구체적 기준을 적용하여 근무환경 만족도와의 연관성을 분석한 연구는 상대적으로 부족하다. 본 연구는 한국 임금근로자를 대상으로 한 달 동안 하루 10시간 이상 근무하는 일수와 근무환경 만족도 간의 연관성을 정량적으로 분석하고자 하였다.
방법
본 연구는 제7차 근로환경조사 자료를 활용한 단면연구이다. 전체 조사 대상자 50,195명 중 18세 미만 근로자, 자영업자 및 무급 가족종사자, 주요 변수에 대한 응답 누락자, 교대근무자를 제외한 24,269명의 임금근로자를 최종 분석 대상으로 선정하였다. 하루 10시간 이상 근무하는 일수는 0일, 1-9일, 10일 이상으로 분류하였다. 근무환경 만족도는 만족과 불만족의 이분형 변수로 재분류하였다. 인구통계학적 특성과 직업적 특성을 보정한 다중 로지스틱 회귀분석을 통해 하루 10시간 이상 근무 일수와 근무환경 만족도 간의 연관성을 분석하였다.
결과
전체 대상자 중 하루 10시간 이상 근무하지 않는 근로자는 95.4%였으며, 1-9일 근무자는 3.3%, 10일 이상 근무자는 1.3%였다. 근무환경 불만족 비율은 하루 10시간 이상 근무 일수가 증가할수록 높아졌다. 보정 후 분석 결과, 하루 10시간 이상 근무 일수가 1-9일인 근로자의 근무환경 불만족 오즈비는 1.380(95%CI: 1.145-1.665), 10일 이상인 근로자는 2.106(95%CI: 1.627-2.725)으로 통계적으로 유의하였다.
결론
본 연구의 분석 대상인 한국 임금근로자 표본에서 하루 10시간 이상 근무는 근무환경 불만족과 유의한 연관성을 보였으며, 장시간 근무 일수가 증가할수록 불만족 수준이 증가하는 용량-반응 양상이 관찰되었다.

Abstract

Background Previous studies have classified cameramen’s job as physiologically heavy work and identified the risk factors of work-related musculoskeletal disorders (WRMDs) in cameramen. However, those studies limited their research subjects to cameramen. In this study, we compared the frequency and severity of WRMDs between cameramen and office workers.
Methods A total of 293 subjects working in four broadcasting companies in Korea were recruited. A questionnaire survey was conducted for a month, starting in October 2016. The subjects were divided into cameramen and office workers according to their occupation. We compared the frequency and severity of WRMDs and ergonomic risk assessment results between the two groups.
Results The high-risk WRMD group had a higher proportion of cameramen than office workers. Moreover, the high ergonomic risk group also had a higher proportion of cameramen than office workers for WRMDs in the upper extremities and waist+lower extremities. In the multivariable-adjusted model comparing cameramen and office workers, the odds ratio (OR) with 95% confidence interval (95% CI) for high-risk WRMDs was 3.50 (95% CI: 1.92–7.72) for the upper extremities and 3.18 (95% CI: 1.62–6.21) for the waist and the lower extremities. The ORs by body parts were 3.11 (95% CI: 1.28–7.57) for the neck, 3.90 (95% CI: 1.79–8.47) for the shoulders, and 4.23 (95% CI: 1.04–17.18) for the legs and feet.
Conclusions Our study suggests that cameramen are at high risk of WRMDs. Workplace improvements and management of the neck, shoulders, and lower extremities, which are susceptible to WRMDs, are necessary to prevent musculoskeletal disorders among cameramen.

- OBJECTIVES
A case-control study was conducted on 2,323 male soldiers(771 herniated nucleus pulposus patients and 1542 controls) to identify risk factors for cumulative trauma disorders especially lower back.
METHODS
The collecting data included individual physical, psychological, and work environmental factors. Korea Military Personality Inventory(KMPI) was used to examine the assess trait that have been associated with clinically with herniated nucleus pulposus. A measurement of the workplace support system was obtained by using of the modified work APGAR, a brief, seven-item workplace function questionnaire.
RESULTS
The herniated nucleus pulposus patients were more common among Artillerymen and Engineer than among infantrymen. In logistic regression analysis of military occupational specialties, Artillerymen, Engineer, radio operator, driver were higher risk of herniated nucleus pulposus than infantrymen. Multivariate analysis of KMPI scales found hypochondriasis scale, hysteria scale, hypomania scale, social introversion scale to have strong relationship to incidence of herniated nucleus pulposus. And 'can communicate with peers' and 'enjoy job task' item of modified work APGAR to have strong relationship to incidence of herniate nucleus pulposus CONCLUSIONS: Study of the relative contributions of many physical and non physical variable shows that evaluations of back problems in workplace that exclude these highly significant work perception and psychosocial variables are of limited value. Simple, unidimensional approaches that ignore the effect of work perceptions and psychological factors on back problems reporting oversimplify a multifaceted problem. These findings emphasize the importance of adopting a broader approach to the multifaceted problem of back complaint in workplace.
