본 연구는 한국노동연구원의 사업체패널조사 1-5차년도 자료와 행정자료인 "고용보험 DB"를 결합하여 구축한 "사업체-근로자 연계자료"를 활용하여 사업체 근로자의 연령구성과 생산성 및 인건비와의 관계를 실증분석 하였다. 사업체의 생산성은 1인당 부가가치로, 인건비는 1인당 노동비용으로, 사업체 근로자의 고령화 정도는 근로자의 연령구성으로 측정하였으며 동적패널모형을 활용하였다. 분석 결과, 생산성과 인건비 모두 사업체의 35-39세 연령대 근로자의 비율을 중심으로 역U자의 모습을 보였다. 즉, 35-39세 연령대 근로자 대신 더 젊은층의 근로자 혹은 더 고령층의 근로자 비중이 증가하는 경우 생산성 및 인건비에 부(-)의 영향을 미치는 것으로 나타났다. 특히, 35-39세 연령대 근로자 대신 50세 이상 연령대 근로자가 증가할 때의 생산성 추정계수와 인건비 추정계수와의 차이가 30세 미만 연령대 근로자가 증가할 때의 생산성 및 인건비의 추정계수와의 차이보다 더 큰 것으로 나타났다. 이러한 분석 결과를 통해 고령근로자의 생산성 저하에 대한 기업의 우려는 타당하나, 동시에 기업은 이미 인건비 조정 등의 방법을 통해 고령근로자를 효율적으로 활용해 왔음도 확인할 수 있다.

Background: Like direct infection from COVID-19, psychological concern about infection could affect health. Concern about COVID-19 infection was associated with individual habits to practice rules for preventing infection. Therefore, this study aimed to check occupational types and whether to practice tooth brushing after lunch depending on the occupation of economic workers and find correlations between concerns about infection due to COVID-19 pandemic and tooth brushing after lunch. Methods: The raw data was from the community health survey conducted in 2020. Among 229,269 adult participants aged 19 years and older, 138,970 economic workers were included in the final analysis. The chi-squared test was used to find differences in psychological concerns due to the COVID-19 pandemic. According to the participants, the rate of practicing tooth brushing after lunch was based on COVID-19-related psychological concerns. Multiple logistic regression analysis was conducted to check the influence of psychological concerns due to the COVID-19 pandemic on the rate of practicing tooth brushing after lunch. Results: According to occupational classifications, professionals and office workers and career soldiers had 1.551- and 1.581-times higher practicing rates than managers, respectively, whereas machine operators, agricultural and fishery sector workers, and daily laborers had lower practicing rates. Regarding COVID-19-related psychological concerns, the group with a lower concern about infection had a 1.076 times higher practicing rate than that with greater concern. The group with greater concern about blame from neighbors had 1.119 times higher practicing rate than that with lower concern. Conclusion: The correlations between higher economic workers' concerns about infection and blame from neighbors and higher recognition of the necessity to prevent COVID-19 and practice tooth brushing after lunch were confirmed. It is necessary to prepare measures for practicing tooth brushing after lunch suitable to the characteristics of occupational types and work environments of economic workers.

Purpose : Delegating authority to employees exerts a positive effect on the efficient operation and service of a company. In particular, investigating how the delegation of authority granted to social workers, who have a greater workload compared with those of other occupations, influences job satisfaction and commitment to the organization is meaningful. Therefore, this study aims to investigate the impact of the empowerment of social workers on job satisfaction and organizational commitment. Methods : Toward this end, surveys were distributed to social workers employed at social welfare facilities in Daegu metropolitan city. Prior to the study, the researcher visited the institutions in which the social workers were working, explained the content in person, and conducted the self-administered survey accompanied by two research assistants who received prior training. Out of the 233 collected responses, those with unreliable responses and missing data were excluded, which left a sample of 224 for analysis. Data were analyzed using SPSS 18.0. Results : First, social workers who were older, had higher positions, and with longer years of service exhibited higher levels of empowerment in terms of differences in empowerment according to general characteristics. Second, for job satisfaction and organizational commitment according to general characteristics, the longer the period of employment, the higher the level of job satisfaction. Third, empowerment exerted an effect on job satisfaction and organizational commitment, and a positive correlation was found. Conclusion : The empowerment of social workers exerted a positive effect on job satisfaction and organizational commitment. Therefore, to improve service quality and the efficient operation of social welfare organizations in this practice, improving the empowerment of social workers is necessary by providing appropriate treatments, improving working environments, and providing appropriate discretion and decision-making authorities that are considered necessary for work performance.

Background: This study aimed to investigate the relationship between work-related communication devices use during work outside of regular working hours and depressive symptoms in wage workers. Methods: Data from 50,538 workers aged 15 years or older who had participated in the 6th Korean Working Condition Survey (KWCS) were used. The final sample was 32,994 wage workers. The questionnaire asked the respondents how often they used communication devices for work during work outside of regular working hours. Depressive symptoms were assessed using WHO-5 Well-Being Index. Multiple logistic regression analysis was used to analyze the association between work-related communication devices use during work outside of regular working hours and depressive symptoms. Results: The rate of depressive symptoms was highest among workers who did not use work-related communication devices during work outside of regular working hours. After adjusting for socio-demographic and work-related factors, the odds ratio of depressive symptoms among workers who used communication devices when working outside of regular working hours was 1.20 (95% CI: 1.09-1.32); the odds ratio of depressive symptoms in the group not using communication devices for free-time work was 1.66 (95% CI: 1.37-2.00), which was higher than that of the reference group, that is, workers who did not work outside of regular working hours, and was statistically significant. Conclusion: Regardless of whether work-related communication devices are used, working outside of regular working hours increases depressive symptoms. The use of work-related communication devices during work outside of regular working hours can reduce the rate of depressive symptoms.
