COVID-19 and remote work inequality: Evidence from South Korea

ABSTRACT Even though remote work in South Korea was very unusual before the pandemic, the COVID-19 pandemic has facilitated remote work, so the ratio of remote workers to total employees increased from 0.5% in 2019 to 5.4% in 2021. In this regard, this study investigated determinants of remote work during the pandemic using the Economically Active Population Survey in 2019, 2020, and 2021 with a logistic regression. Since the Korean government did not impose a national lockdown and business owners introduced remote work voluntarily, this study can identify significant heterogeneity. First, younger, female, highly-educated, and high-earning workers are more likely to work remotely. Second, large firms tend to provide more remote work opportunities to their employees. Lastly, ICT, finance, and education sectors present high probabilities to remote work. In recent times, remote work has been considered an important trigger to alleviate long working hours and improve work-life balance in Korea; however, it is also necessary to relieve remote work inequality.

The findings offer a useful view for integrating insights from different research streams.

Working for Long Hours Is Associated With Dietary Fiber Insufficiency.

It has been suggested that long working hours are associated with various diseases through dietary patterns. However, few studies have reported the association between working hours and dietary habits. Thus, the objective of this cross-sectional study was to explore the difference in dietary fiber intake by working hours. Data of a total of 10,760 workers in South Korea who participated in the Korea National Health and Nutrition Survey (KNHANES), a nation-wide survey, were analyzed to determine different distributions of dietary fiber insufficiency using multiple logistic regression models. Fiber insufficiency proportion was different from working hour groups. 70.1% of the total population eat fiber insufficiently. Working <40 h group showed 66.8% of fiber insufficiency. But working more than 52 h group marked 73.2% of fiber insufficiency. Logistic regression analysis of 10,760 nation-wide study participants revealed that working for 41–52 h a week (OR: 1.32, 95% CI: 1.18–1.47) and working for over 52 h a week (OR: 1.42, 95% CI: 1.25–1.62) were significantly associated with insufficient fiber intake compared to workers with standard working hours (30–40 h a week). These associations were still robust in an adjusted model, with working for 41–52 h a week (OR: 1.13, 95% CI: 1.01–1.27) and working for over 52 h (OR: 1.26, 95% CI: 1.09–1.45) showing high associations with dietary fiber insufficiency. Those with long working hours tend to have insufficient intake of dietary fiber. To promote desirable dietary habits, intervention programs on working conditions should be considered.

Predictors of Health Promotion Behaviors Among Working Adults at Risk for Metabolic Syndrome.

Metabolic syndrome has a high global prevalence, affecting 26% of South Koreans. Lifestyle modifications have shown benefits in studies involving health behavior enhancement, specifically through workplace eating and exercise interventions. However, workplace interventions focusing on health behaviors have been inadequately explored. This study examined factors affecting health promotion behaviors of workers at high risk of metabolic syndrome by applying Theory of Planned Behavior constructs (attitude, subjective norm, perceived behavioral control, and intention). This correlational cross-sectional study collected survey data from 164 hotel workers in South Korea. The study applied factor analysis and structural equation modeling for the data analysis. Analysis revealed five health promotion behaviors: exercise, making healthy food choices, avoiding fatty foods, eating a nutritious and balanced diet, and eating regular moderate meals. Participants were grouped as total participants, those with one risk factor, and those with two risk factors. In the "total" group, four behaviors were influenced by perceived behavioral control: exercise, making healthy food choices, eating a nutritious and balanced diet, and eating regular moderate meals. In the "one risk factor" group, intention and attitude influenced the eating regular moderate meals behavior, and two other behaviors were influenced by perceived behavioral control: exercise and eating a nutritious and balanced diet; in the "two risk factor" group, only perceived behavioral control directly affected exercise. Perceived behavioral control was a key predictor of health behaviors, and theory constructs partially explained behaviors. Perceived behavioral control influenced four behaviors and influenced exercise in all three groups. Also, theory constructs showed a greater effect on behaviors in the one risk factor group than in the two risk factor group, indicating that participants with one risk factor more effectively managed their behaviors on their own and with healthcare providers' support. Occupational health providers should conduct early assessments of workers showing metabolic syndrome risk factors to identify their particular risks, intention, and behaviors. As the number of risk factors affects behaviors and perceived behavioral control primarily influences exercise, these findings should be incorporated in metabolic syndrome interventions.

How to Enhance Smart Work Effectiveness as a Sustainable HRM Practice in the Tourism Industry

With the development of information technologies and increasing interest in sustainability, many companies have adopted smart work as a sustainable human resource practice. Moreover, the outbreak of COVID-19 has further promoted smart work in the workplace. However, the benefits and disadvantages of smart work are still under debate. In this regard, this study attempted to delve into how to enhance smart work implementation by exploring employees’ subjectivity. Hana Tour, which is considered a good model of smart work in South Korea, was selected as a sample company. Q-methodology was employed to listen to employees’ subjective opinions about smart work that they experienced. This study identified five types of smart work perceptions, namely, “self-development and energy saving,” “quality of personal life,” “job satisfaction,” “work engagement,” and “work–life balance”. Based on these five types, the theoretical and practical implications are discussed in the last chapter. Interestingly, the results showed that employees were not well aware of smart work effectiveness as one of the environmental protection practices in sustainability management paradigms. Another notable result was that employees were not concerned about the potential penalties of their engagement in smart work. During the current COVID-19 pandemic, the study’s findings are beneficial to the improvement of smart work implementation as a sustainable HRM practice in business.

Desalination Technology in South Korea: A Comprehensive Review of Technology Trends and Future Outlook.

Due to advances in desalination technology, desalination has been considered as a practical method to meet the increasing global fresh water demand. This paper explores the status of the desalination industry and research work in South Korea. Desalination plant designs, statistics, and the roadmap for desalination research were analyzed. To reduce energy consumption in desalination, seawater reverse osmosis (SWRO) has been intensively investigated. Recently, alternative desalination technologies, including forward osmosis, pressure-retarded osmosis, membrane distillation, capacitive deionization, renewable-energy-powered desalination, and desalination batteries have also been actively studied. Related major consortium-based desalination research projects and their pilot plants suggest insights into lowering the energy consumption of desalination and mitigation of the environmental impact of SWRO brine as well. Finally, considerations concerning further development are suggested based on the current status of desalination technology in South Korea.

Healthcare Workers in South Korea Maintain a SARS-CoV-2 Antibody Response Six Months After Receiving a Second Dose of the BNT162b2 mRNA Vaccine.

BackgroundEffective vaccines against coronavirus disease 2019 (COVID-19) are available worldwide; however, the longevity of vaccine effectiveness is not known.ObjectiveWe performed a prospective observational study to assess the antibody response of healthcare workers against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) after BNT162b2 mRNA COVID-19 vaccination.MethodsSARS-CoV-2 neutralizing antibody (nAb) and spike (S) protein-IgG (S-IgG) antibody titers were examined in participants who received two doses of the BNT162b2 mRNA COVID-19 vaccine in a single center between March 1, 2021, and October 11, 2021. Antibody levels were analyzed at four times: before vaccination (visit 1), 4 weeks after the first vaccination (visit 2), 3 months after the second vaccination (visit 3), and 6 months after the second vaccination (visit 4).ResultsA total of 249 healthcare workers at Jeju National University Hospital were enrolled in this study, and 982 blood samples were analyzed. The mean age was 38.1 ± 9.5 years, and 145 (58.2%) participants were females. Positive nAbs (inhibition rates ≥ 20%) were measured in 166/249 (66.7%) subjects at visit 2, 237/243 (97.5%) subjects at visit 3, and 150/237 (63.3%) subjects at visit 4. A S-IgG (≥50 AU/mL) positivity was detected in 246/249 (98.8%) subjects at visit 1, and all participants had positive S-IgG antibody levels at visits 3 and 4 after being fully vaccinated. Further analysis of S-IgG levels revealed a median quantitative antibody level of 1275.1 AU/mL (interquartile range [IQR] 755.5–2119.0) at visit 2, 2765.9 AU/mL (IQR 1809.8–4138.4) at visit 3, and 970.1 AU/mL (IQR 606.0–1495.9) at visit 4. Patient characteristics, such as age, body mass index, and comorbidity, had no relationship with nAb or S-IgG levels at any of the visits. Considering the change in antibody levels over time, both nAb and S-IgG levels at visit 4 decreased compared with the corresponding levels at visit 3. No evidence of SARS-CoV-2 infection was found among any of the participants throughout the study.ConclusionsThe BNT162b2 mRNA vaccine was effective in protecting healthcare personnel working in COVID-19-related departments. While the level of S-IgG antibodies was maintained for 6 months after the second vaccination, nAb levels waned over this 6-month period, indicating the need for a booster vaccination in some healthcare workers 6 months after full vaccination. Herein, we suggest that further studies are needed to evaluate the need for an interval of booster vaccination after full vaccination.

Oral health inequality among Indonesian workers in South Korea: role of health insurance and discrimination factors

BackgroundThe health of migrant workers is becoming an important public health issue. Although there are an increasing number of migrant workers in Korea, the health status in migrant populations remains unknown. The aims of this study were (1) to evaluate the association between income and self-rated oral health (SROH), and (2) to assess the role of health insurance and self-perceived discrimination in the association between income and SROH among Indonesian migrant workers in Korea.MethodsInformation about self-reported income, SROH, coverage/utilization of health insurance (HI), living difficulties related to oral health (LDROH), oral health literacy (OHL), and discrimination were obtained from Indonesian migrant workers in Korea (n = 248). The main explanatory variable was income, and SROH was an outcome variable. Logistic regression analyses were performed controlling for age, gender, HI, LDROH, OHL, and discrimination. The paths from income to SROH were analyzed using the Partial Least Square-Structural Equation Model (PLS-SEM).ResultsAmong Indonesian migrant workers, the lower income group had the highest probability of a poor SROH compared to the higher income group. The variables showing a high explanatory power were discrimination among the low income group and HI among the middle income group. In PLS-SEM, the variables such as HI, LDROH, OHL, and discrimination contributed 11% to explaining the association between income and SROH.ConclusionA monotonic gradient was revealed among migrant workers according to the association between income and SROH. Discrimination and HI contributed to oral health inequalities.

Comparing SARS-CoV-2 Antibody Responses after Various COVID-19 Vaccinations in Healthcare Workers.

Coronavirus disease 2019 (COVID-19) vaccination began for healthcare workers in South Korea at the end of February 2021. This study investigated severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibody responses after various COVID-19 vaccinations in healthcare workers. Blood specimens of 497 vaccinated healthcare workers were collected. Inoculated vaccines were ChAdOx1 (AstraZeneca/Oxford), BNT162b2 (Pfizer/BioNTech), JNJ-78436735 (Janssen), and mRNA-1273 (Moderna). Each specimen was tested for antibodies against SARS-CoV-2 using Elecsys Anti-SARS-CoV-2 S assay (Roche Diagnostics), SARS-CoV-2 IgG II Quant assay (Abbott), and R-FIND SARS-CoV-2 Neutralizing Antibody kit (SG medical Inc.). A questionnaire was used to investigate adverse events related to vaccination. We found that 99.5% of the subjects showed a 96–100% positive rate in all three antibody assays, regardless of the vaccine type. The antibody-positive rate of completed vaccination groups reached 96–100%, and antibody quantities significantly increased 2 weeks after vaccination. The antibody values measured approximately 3 months after BNT162b2 inoculation significantly correlated with adverse events.

Digital industrial accidents: A case study of the mental distress of platform workers in South Korea

AbstractThe increase in the number of platform workers has led to active discussions on the various difficulties they face. Existing studies on their work‐related accidents have focused on physical, traffic‐related accidents in offline places. However, platform workers are more likely to suffer from psychological stress or illnesses while performing immaterial and cognitive labour in the virtual space. Through in‐depth interviews with 30 platform workers in South Korea, this study investigated platform workers’ mental distress and identified five common psychological problems: (a) stress from real‐time assessment in public space; (b) exhaustion from working without work‐life boundaries; (c) infringement of privacy through exposure of private life; (d) verbal abuse in non‐face‐to‐face relations; and (e) isolation from working alone. In doing so, this study seeks to define the mental difficulties of platform workers as digital industrial accidents and asserts the need to establish a new social security system for the digital economy.

High Work-Related Stress and Anxiety as a Response to COVID-19 Among Health Care Workers in South Korea: Cross-sectional Online Survey Study.

BackgroundThe COVID-19 outbreak had a severe impact on health care workers' psychological health. It is important to establish a process for psychological assessment and intervention for health care workers during epidemics.ObjectiveWe investigated risk factors associated with psychological impacts for each health care worker group, to help optimize psychological interventions for health care workers in countries affected by the COVID-19 pandemic.MethodsRespondents (n=1787) from 2 hospitals in Korea completed a web-based survey during the period from April 14 to 30, 2020. The web-based survey collected demographic information, psychiatric history, and responses to the 9-item Stress and Anxiety to Viral Epidemics (SAVE-9), 9-item Patient Health Questionnaire (PHQ-9), and 7-item Generalized Anxiety Disorder-7 (GAD-7) scales. We performed logistic regression to assess contributing factors as predictor variables, using health care workers’ depression as outcome variables.ResultsAmong 1783 health care workers, nursing professionals had significantly higher levels of depression (PHQ-9 score: meannurse 5.5, SD 4.6; meanother 3.8, SD 4.2; P<.001), general anxiety (GAD-7 score: meannurse 4.0, SD 4.1; meanother 2.7, SD 3.6; P<.001), and virus-related anxiety symptoms (SAVE-9 score: meannurse 21.6, SD 5.9; meanother 18.6, SD 6.3; P<.001). Among nursing professionals, single workers reported more severe depressive symptoms than married workers (PHQ-9 score ≥10; meannurse 20.3%; meanother 14.1%; P=.02), and junior (<40 years) workers reported more anxiety about the viral epidemic (SAVE-9 anxiety score; meannurse 15.6, SD 4.1; meanother 14.7, SD 4.4; P=.002). Logistic regression revealed that hospital (adjusted odds ratio [OR] 1.45, 95% CI 1.06-1.99), nursing professionals (adjusted OR 1.37, 95% CI 1.02-1.98), single workers (adjusted OR 1.51, 95% CI 1.05-2.16), higher stress and anxiety to the viral infection (high SAVE-9 score, adjusted OR 1.20, 95% CI 1.17-1.24), and past psychiatric history (adjusted OR 3.26, 95% CI 2.15-4.96) were positively associated with depression.ConclusionsPsychological support and interventions should be considered for health care workers, especially nursing professionals, those who are single, and those with high SAVE-9 scores.

The effects of job demands and resources on turnover intention: The mediating roles of emotional exhaustion and depersonalization.

Although job demands, supervisory support, and burnout have been identified as significant predictors of turnover intention, little attention has been paid to the mechanisms among these determinants. Based on the job demand and resource (JD-R) model, this study examined the mediating roles of emotional exhaustion and depersonalization. Data were collected from private sector social workers in three metropolitan areas of South Korea (N = 316). Two serial multiple mediation analyses were conducted to examine the mediating effects of emotional exhaustion and depersonalization in the relationships between job demands and turnover intention and between job resources and turnover intention, respectively. Job demands and resources were associated with turnover intention both directly and indirectly, through emotional exhaustion and depersonalization. Whereas job demands were positively associated with emotional exhaustion only, job resources were negatively associated with both emotional exhaustion and depersonalization. The sequential link from emotional exhaustion to depersonalization was present in both job demands and in the resources models. The findings underscore the importance of addressing potential burnout to effectively reduce turnover intention among social workers in South Korea. Implications and strategies for developing interventions and policies to reduce turnover by improving work environments are suggested.

Association between Near Work Time and Depression among Workers in South Korea.

BackgroundThe aim of this study was to evaluate the association between near work time and depression. MethodsData of 1,551 workers aged 19–49 years from the sixth Korea National Health and Nutrition Examination Survey were examined. The Patient Health Questionaire-9 scores were used to screen for depression. Participants who scored a total of 10 or above, which is suggestive of the presence of depression, were classified as the depression group; the rest were classified as normal. The correlation between daily near work time and depression was analyzed using multivariate logistic analysis after adjusting for other sociodemographic and health behavior-related variables. ResultsMultivariate logistic analysis found that workers with 3 or more hours of near work were more likely to report depression compared to the reference group who had 2 or fewer hours per day of near work (adjusted odds ratio, 2.471; 95% confidence interval, 1.062–5.747). ConclusionLonger near work time was associated with depression among South Korea’s workers. Therefore, it is necessary to reduce near work time to prevent depression.

Association between labor union presence and return to work after occupational injury or illness: A nationally representative longitudinal study in South Korea.

This study sought to examine the association between labor union presence and return to work after occupational injury or illness (RTW) among workers in South Korea. We analyzed the first (2018) and second (2019) wave data from the Panel Study of Workers' Compensation Insurance in South Korea. The cohort consisted of 3,294 workers who had suffered occupational injury or illness and completed their convalescence by 2017. We examined whether RTW was associated with the presence of labor unions in the workplace at the time of the occupational injury or illness occurred. Compared to workers without labor unions, those with labor unions were more likely to report RTW (prevalence ratio: 1.35, 95% confidence interval: 1.20-1.51) after adjusting for potential confounders, including employment status, duration of convalescence, and severity of injury or illness. This study found that labor union presence was associated with RTW among workers who suffered occupational injury or illness in South Korea.

Leisure Factors Predicting the Happiness of Self-Employed Workers in South Korea.

South Korea’s employment status is characterized by a high rate of self-employment and many small-scale self-employed businesses with no employees. This study explored leisure factors relating to self-employed individuals’ subjective happiness based on data from the 2019 National Leisure Activity Survey. The extracted data (N = 2343) were analyzed using descriptive statistics, t-test, ANOVA, Pearson’s correlation coefficient, Kendall’s τb coefficient, Eta correlation coefficient, phi coefficient, and Cramer’s V. And a three-step hierarchical regression analysis was performed to identify multidimensional variables that predict happiness more effectively. In Model 3, which additionally inserted positive and intrinsic factors into Model 2, the explanatory power was significantly increased. The predictors of subjective happiness among self-employed people identified in the final regression model were high economic status (β = 0.05), perceived health status (β = 0.32), financial constraints (β = −0.09), leisure recognition (β = 0.20), and work–life balance (leisure-oriented β = 0.09; work-oriented β = −0.13). This study’s findings will contribute to the establishment of basic data, to prepare empirical measures to improve self-employed individuals’ quality of life.

Response to COVID-19 in social welfare facilities and the psychological state of social workers in South Korea: The mediating role of satisfaction with government.

This paper investigated associations between COVID‐19 responses in social welfare facilities and the psychological state of social workers together with the potential mediating role of satisfaction with the government. During the COVID‐19 pandemic, following government guidelines, social workers have continued to provide social services to the vulnerable groups. However, no research has been conducted focusing on their psychological state. A cross‐sectional survey was carried out in Incheon Metropolitan City, South Korea. Data from 332 participants were analyzed using structural equation modeling. Supplementary in‐depth interviews were conducted with social workers. Analysis results show that higher levels of preventive measures against COVID‐19 directly worsen levels of well‐being, but this negative effect is offset by the satisfaction with the government (β = .383, p < .001). In social workers, satisfaction with the government fully mediates the influence of preventive measures toward reduced negative emotionality (β = −.288, p < .001). The implications of this study suggest that the government's active response to the social welfare sector is important to alleviate the negative psychological consequences of social workers.

PHI-011 - Current status of hepatitis A virus and measles immunity in secondary hospital workers in South Korea

PHI-011 - Current status of hepatitis A virus and measles immunity in secondary hospital workers in South Korea

Seroepidemiologic survey of emerging vector-borne infections in South Korean forest/field workers.

With global warming and lush forest change, vector-borne infections are expected to increase in the number and diversity of agents. Since the first report of severe fever with thrombocytopenia syndrome (SFTS) in 2013, the number of reported cases has increased annually in South Korea. However, although tick-borne encephalitis virus (TBEV) was detected from ticks and wild rodents, there is no human TBE case report in South Korea. This study aimed to determine the seroprevalence of TBEV and SFTS virus (SFTSV) among forest and field workers in South Korea. From January 2017 to August 2018, a total 583 sera were obtained from the forest and field workers in South Korea. IgG enzyme-linked immunosorbent assay (ELISA) and neutralization assay were conducted for TBEV, and indirect immunofluorescence assay (IFA) and neutralization assay were performed for SFTSV. Seroprevalence of TBEV was 0.9% (5/583) by IgG ELISA, and 0.3% (2/583) by neutralization assay. Neutralizing antibody against TBEV was detected in a forest worker in Jeju (1:113) and Hongcheon (1:10). Only 1 (0.2%) forest worker in Yeongju was seropositive for SFTSV by IFA (1:2,048) and neutralizing antibody was detected also. In conclusion, this study shows that it is necessary to raise the awareness of physicians about TBEV infection and to make efforts to survey and diagnose vector-borne diseases in South Korea.

Perkembangan Wisata Halal di Korea Selatan (Studi Kasus Perspektif Masyarakat Indonesia di Korea Selatan)

The large number of tourists, students, and Muslim migrant workers in South Korea has prompted the South Korean government to start developing various kinds of halal tourism programs. These programs are very interesting and helpful for tourists, students and Muslim migrant workers to visit or live in South Korea. To find out the extent of the development of halal tourism in South Korea, this study was conducted using a descriptive -quantitative method with Indonesian people in South Korea as the object of this research. The object of this study was selected because of the large number of tourists, students, and Indonesian workers in South Korea and the majority of them as Muslim can represent other Muslim communities in South Korea. The results of this study indicate that Muslim-friendly facilities such as halal restaurants, halal food shopping applications, mosques, and prayer rooms in South Korea are quite numerous and scattered in various cities. This is certainly welcomed positively by tourists and the Muslim communities in South Korea. However, there are several things that Korean government still needs to pay attention to, especially related to the socialization of halal food that there is a standardization and process in it.&#x0D; Keywords: Halal Tourism, South Korea, Tourism, Halal Korea, Halal Food
