Background: The aim of the present study was to evaluate the psychological well-being (PWB) during the coronavirus disease (COVID-19) pandemic in workers of a multinational company. Methods: Employees (aged ≥18 years) were recruited from Latin American, North American, New Zealand, and European sites of a multinational company operative during all the pandemic period. The self-reported Psychological General Well-Being Index was used to assess the global PWB and the effects on six subdomains: anxiety, depressed mood, positive well-being, self-control, general health, and vitality. The influencing role of age, gender, geographical location, COVID-19 epidemiology, and restrictive measures adopted to control the pandemic was explored. Results: A total of 1335 workers completed the survey. The aggregate median PWB global score was in a positive range, with significantly better outcomes detected in the Mexican and Colombian Latin American sites compared with the other worldwide countries (p < 0.001). Among the European locations, a significantly higher PWB score was determined in Spain compared with the German and French sites (p < 0.05). Comparable geographical trends were demonstrated for all the PWB subdomains. Male workers had a significantly better PWB compared with females (p < 0.05), whereas a negative correlation emerged with aging (p = 0.01). COVID-19 epidemiology and pandemic control measures had no clear effects on PWB. Conclusion: Monitoring PWB and the impact of individual and pandemic-related variables may be helpful to clarify the mental health effects of pandemic, define targeted psychological-supporting measures, also in the workplace, to face such a complex situation in a more constructive way.

1인 가구의 고용형태에 따라 비만 및 고혈압 유병의 영향요인에 차이가 있는지를 확인하고자, 경제활동을 하는 20세에서 59세까지의 1인 가구를 정규직, 비정규직으로 분류하여 층화추출 후 질병 유무, 경제적 특성, 건강행태 등을 조사하였다(n=566). 고혈압과 비만 여부에 대해서 각각 로지스틱 회귀분석 결과, 고혈압에는 고용형태와 관련 없이 연령과 비만도가 높을수록 유의적으로 정(+)의 영향을 주었으며, 특히 비정규직의 경우 소득이 낮을수록 고혈압을 갖고 있는 경우가 많았다(p<0.001). 비만 유병률은 고용형태와 관련 없이 여성의 경우 남성에 비해서 유의적으로 더 낮았고, 특히 비정규직은 저녁식사의 충실도가 낮을수록 비만 유병률이 높았다(p<0.001). 이러한 결과로 볼 때, 소득 수준이 낮고 저녁식사의 충실도가 낮은 비정규직 1인 가구 대상으로 고혈압 및 비만 등의 만성질환 관리를 위한 방안이 더욱 실질적으로 제시되어야 할 것으로 사료된다.

Purpose: This study aimed to understand how changes in income due to the COVID-19 pandemic have affected the health behavior and mental health status of self-employed individuals. Methods: We compared the health behavior and mental health status of regular wage workers and self-employed individuals with no change in income, with that of self-employed individuals with reduced income due to the spread of COVID-19. Results: Smoking status, average amount of smoking per day, changes in the amount of smoking and drinking due to COVID-19, drinking frequency per year, monthly binge drinking experiences, subjective stress, and suicidal thoughts experienced by self-employed individuals with decreased income were not only higher than those of wage workers and self-employed individuals with maintained income, but their happiness index was also lower than the latter group. Conclusion: This study suggests that the change in total household income due to COVID-19 adversely affects the health behavior and mental health status of self-employed individuals. However, COVID-19-related policies focus only on economic loss compensation, and the health behavior and mental health management for self-employed individuals is insufficient. Therefore, it is necessary to establish policies for health behavior and mental health management of self-employed individuals.

Background: Effort-reward imbalance (ERI) and overcommitment at work have been associated poorer mental health. However, nonlinear and nonadditive effects have not been investigated previously. Methods: The association between effort, reward, and overcommitment with odds of poorer mental health was examined among a sample of 68 formal United States waste workers (87% male). Traditional, logistic regression and Bayesian Kernel machine regression (BKMR) modeling was conducted. Models controlled for age, education level, race, gender, union status, and physical health status. Results: The traditional, logistic regression found only overcommitment was significantly associated with poorer mental health (IQR increase: OR = 6.7; 95% CI: 1.7 to 25.5) when controlling for effort and reward (or ERI alone). Results from the BKMR showed that a simultaneous IQR increase in higher effort, lower reward, and higher overcommitment was associated with 6.6 (95% CI: 1.7 to 33.4) times significantly higher odds of poorer mental health. An IQR increase in overcommitment was associated with 5.6 (95% CI: 1.6 to 24.9) times significantly higher odds of poorer mental health when controlling for effort and reward. Higher effort and lower reward at work may not always be associated with poorer mental health but rather they may have an inverse, U-shaped relationship with mental health. No interaction between effort, reward, or overcommitment was observed. Conclusion: When taking into the consideration the relationship between effort, reward, and overcommitment, overcommitment may be most indicative of poorer mental health. Organizations should assess their workers' perceptions of overcommitment to target potential areas of improvement to enhance mental health outcomes.

본 논문에서는 취업형태를 정규직 임금근로, 비정규직 임금근로 및 자영업의 세 유형으로 구분하여 한국노동패널 자료에 포함된 남자근로자들의 전직에 따른 취업형태의 변화를 살펴보았으며, 또한 경쟁적 위험도 모형을 추정함으로써 이들의 재취업시의 취업형태의 결정에 영향을 미치는 요인들에 대한 분석을 행하였다. 분석 결과에 의하면 퇴직한 일자리애서의 취업형태가 새 일자리에서의 취업형태를 결정하는 데에 중요한 영향을 미치며, 또한 직장이동이 반복되는 경우 그 영향력이 점차로 약화되기는 하나 직전 직장 이전에 취업했던 일자리에서의 취업형태도 새 직장에서의 취업형태의 결정에 영향을 미치는 것으로 나타났다. 즉 직전 직장에서 비정규직으로 근무하다 실직한 근로자는 전직 이전의 직장에서 정규직으로 취업했던 근로자에 비해 정규직에 재취업할 가능성은 크게 낮은 반면 또다시 비정규직에 재취업할 가능성온 크게 높은 것으로 분석되었다. 마찬가지로 퇴직한 직장에서의 취업 형태가 자영직이었던 근로자는 전직 이전의 직장에서 정규직으로 취업했던 근로자에 비해 정규직에 재취업할 가농성은 크게 낮은 반면, 또다시 자영직에 재취업할 가능성은 크게 높은 것으로 분석되었다. 이러한 분석결과는 우리나라 남자근로자의 경우 비정규직 또는 자영직 일자리가 막다른 일자리로서의 성격을 가진다고 단정할 수는 없다고 하더라도 일단 비정규직 또는 자영직에 취업한 근로자가 전직을 통해 정규직 일자리로 옮겨가기가 쉽지 않음을 보여주는 것이라 생각된다. 이와 함께 실업률이 높아질수록 정규직과 자영직에의 취업 가능성은 낮아지나 비정규직에의 취업 가능성은 오히려 높아지는 것으로 나타났는데, 이는 노동시장에서의 수급조건이 근로자에게 불리할수록 노동시장의 비정규화가 빠른 속도로 진행될 수 있음을 의미하는 것으로 해석된다.

IRP의 경제적인 유인체계가 뚜렷하지 않은 상황에서 가입자의 대다수가 퇴직급여를 받은 후 IRP 계좌를 즉시 해지하고 있어, IRP가 미래 연금소득의 가교역할을 제대로 수행하지 못하고 있다. 본 연구에서는 현재 퇴직급여 및 IRP 제도의 선택 원리를 근로자와 정부의 경제적 의사결정 모형을 통해 고찰한다. 이론 모형의 분석결과 미래 IRP 유지의 선택 문제는 현재 근로자의 퇴직급여 선택에 영향을 미치며, 노후소득보장을 위해 정부가 퇴직연금을 극대화하기 위해서는 근로자의 퇴직금 선택을 억제하는 것이 필요하다. 이를 위해 근로자가 퇴직금을 선택하지 않도록 퇴직금에 대해서도 IRP의 자동 전환이 필요한 것으로 분석되었다. 이는 점진적으로 이원화된 퇴직급여 체계가 퇴직연금으로 단일화되는 효과를 발생시킬 것이다. 또한, 퇴직연금사업자의 IRP 가입자 자료를 바탕으로 IRP 해지에 영향을 미치는 가입자 특성에 관해 실증분석을 한 결과, 상대적으로 높은 연령층, 입금액이 많은 고객, 남성이 즉시 해지할 확률이 높은 것으로 나타났고, 업종별로도 차이가 발생하는 것으로 나타났다. 실증분석 결과를 통해 볼 때, IRP 유지율을 높이기 위해서는 가입자의 특성을 고려한 다양한 경제적 유인체계를 설계해야 할 것이다.

Objectives: The purpose of this study is to provide basic data for the improvement of the working environment for health prevention and related countermeasures for shift workers. This study was conducted based on the Fifth Korean Working Conditions Survey (KWCS), which analyzed the health effects of shift work forces and compared them with preceding studies. Methods: By analyzing secondary rates using raw data from the 5th KWCS, 4,870 (9.7%) of the 50,184 total study subjects were divided into shift work and 45,314 (90.3%) non-shift work groups based on the response to shift status. Variables that could affect work health issues were identified and corrected. A cross-analysis was conducted to examine demographic characteristics (gender, age, and education level) of the workers and occupation characteristics (monthly net earnings, employment type, occupation, working period up to now, workplace scale, type of work system, and weekly working hours). In order to find the work health issue ratio between the shift and non-shift work groups, logistic regression was analyzed and the association with health problems according to shift type by gender was looked at through cross-analysis. Results: According to the surveys conducted from the 1st KWCS (2006) to the 5th KWCS (2017), the proportion of shift workers continued to increase. Also, muscular pains in the lower limbs (hips, legs, knees, feet, etc.) (OR=1.135, 95%CI 1.031-1.251), headaches, eyestrain (OR=1.580, 95% CI 1.428-1.748), anxiety (OR=1.715, 95% CI 1.402-2.099), difficulty falling asleep (OR=1.391), and other problems (OR=7.392) were reported. In addition, back pain, muscular pains in shoulders, neck and/or upper limbs, muscular pains in lower limbs (hips, legs, knees, feet, etc.), headaches, eyestrain, depression, anxiety, overall fatigue resulted in significant results for both male and female shift workers. Depression and anxiety were higher in female shift/circulation compared to males. Conclusions: The social nets for the health and safety of shift workers should be explored in a variety of ways, including management and supervision of shift sites, attempts to reorganize and improve the shift system, development of workers' health recovery programs, promotion, systematic treatment, and compensation systems.

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.

Objective: Chronic obstructive pulmonary disease(COPD) is characterized by persistent airflow limitations associated with chronic inflammatory response due to noxious particles or gases in the lung. Iron deficiency is associated with chronic inflammation, such as COPD. The aim of this study was to evaluate the relationship among iron deficiency, iron homeostasis, and inflammation in retired miners with COPD. Methods: The serum levels of ferritin, soluble transferrin receptor(sTfR), and transferrin saturation(TSat) as biomarkers for iron deficiency and high-sensitivity C-reactive protein(hsCRP) as a biomarker for inflammation and hepcidin as a biomarker for iron homeostasis were measured in 93 male subjects. Iron deficiency was defined as any one or more of (1) sTfR>28.1 nmol/L, (2) TSat<16%, and (3) ferritin< $12{\mu}g/L$. Results: Iron deficiency was found 28% of the study subjects. Median levels of serum hsCRP was significantly increased related to airflow limitation of COPD(GOLD 1, $0.09{\mu}g/dL$ vs. GOLD 2, $0.17{\mu}g/dL$ vs. GOLD $3{\leq}$, $0.30{\mu}g/dL$, p=0.010), and was positively correlated with hepcidin(p=0.009). Mean level of serum hepcidin was lower in COPD subjects with iron deficiency(p=0.004) and serum levels of hepcidin was negatively correlated with %$FEV_1$ predicted(p=0.030). Conclusions: These results suggest that high serum levels of hepcidin are related to severe airflow limitation or inflammation and can decrease iron availability, regardless of iron status.

Purpose: This study was conducted to identify the clinical characteristics and risk factors on the occurrence of variant angina, and to examine the predicting factors on the vascular endothelial dysfunction of the patients with variant angina. Methods: A total of 134 patients diagnosed with variant angina were recruited from 2006 to 2008. The degrees of endothelial dysfunction were measured and recorded by the researcher using the values of flow-mediated vasodilation of their brachial arteries and Nitroglycerine-mediated dilation. Subjects' demographic data and risk factors were gathered after obtaining informed consent, and their electronic medical records were reviewed to collect laboratory data. Results: The mean age was $54.2{\pm}9.6$ years and 52% was male patients. More than 50% of the male patients were cigarette smokers and had hypercholesterolemia. 84% of the male patients and 70% of the female patients had more than one risk factor of cardiovascular disease. A stepwise multiple regression analysis showed that smoking and hypercholesterolemia predicted the decrease of flow-mediated vasodilation (Adjusted $R^2$ = .204, p < .001). Conclusion: Tailored educational interventions for smoking cessation and cholesterol management are needed to prevent recurrence of angina attack for patients with variant angina and to prevent cardiovascular disease for middle-aged workers.
