In the labor-intensive construction site, potential threats of the musculoskeletal diseases mainly caused by various repetitive physical tasks, vulnerable environment, and the aging of the labor worker exist. However, quantitative measuring method of construction labor worker's work posture has not been improved yet. This study proposed musculoskeletal measuring method by using wearable motion recognition sensor for quantitative evaluation and analysis of working posture of construction workers. This method is expected to be used as a basic data for posture analysis and prevention construction safety accidents, as well as physical workload and labor productivity analysis by labor work type.

We examine how certain occupational physical requirements affect labor transitions of disabled workers by exploiting a unique feature of South Korean Disability Insurance (DI), where award rules are based solely on an applicant's medical condition, independent of his previous occupations. We estimate the labor market response to a health shock by constructing a physical intensity measure from O^⁎NET and applying it to longitudinal South Korean household panel data. Our results suggest that health shocks initially lead to a 14 to 20 percent drop in employment and that this effect is greater for workers who previously held physically demanding occupations. Those who remain part of the labor market exhibit higher occupational mobility toward less physically demanding jobs. These findings imply that the magnitudes of income risks associated with health shocks vary depending on occupational and skill characteristics.

Traditionally, the construction industry has shown low labor productivity and productivity growth. To improve labor productivity, it must first be accurately measured. The existing method uses work-sampling techniques through observation of workers' activities at certain time intervals on site. However, a disadvantage of this method is that the results may differ depending on the observer's judgment and may be inaccurate in the case of a large number of missed scenarios. Therefore, this study proposes a model to automate labor productivity measurement by monitoring workers' actions using a deep learning-based pose estimation method. The results are expected to contribute to productivity improvement on construction sites.

This study examined the perceptions of emotional labor among the National General Hospital and Private General Hospital in Chungcheong area. The purpose of this study is to examine the perceptions difference of public and private general hospitals. In addition, we tried to analyze the effect of emotional labor on organizational commitment by distinguishing between workers in National and Private General Hospitals. The purpose of this study is to provide the theoretical base data for mitigating emotional labor of hospital workers in the future. The results of the analysis are as follows: First, In the case of employees working at the National General Hospital, the influence of the emotional labor of the hospital workers on the organizational commitment of the hospital workers increased as the frequency of emotional expression increased. However, it was found that as attentiveness of emotional expression and emotive dissonance deepened, the degree of organizational commitment of hospital workers decreased. On the other hand, the influence of emotional labor of the hospital workers on the organizational commitment of the hospital workers in the Private General Hospital was found to be better in the organizational commitment as they pay more attention to emotional expression. However, in the case of emotive dissonance, The more deeply emotive dissonance, the less the organizational commitment of Private General Hospital workers. Second, the frequency of emotional expression in the hospital workers' perception difference of emotional labor was higher than that of the National General Hospitals. However, in the variety of emotional expression, it was confirmed that the employees of the Private General Hospitals had more varied expressions of emotions than those of the National General hospitals. In addition, it was found that the difference of recognition of the organizational commitment of the hospital workers according to the type of hospital work was higher in the organizational commitment of the employees of the National General Hospital than those of the Private General Hospitals.

The purpose of this study is to investigate the mediated effect of superior and co-worker support in the relationship between emotional labor and job performance of social workers working in social welfare facilities The research method is based on the results of a survey of 445 social workers working at social welfare facilities in the Seoul metropolitan area. The collected data are analyzed using SPSS V22.0 as follows. First, it had been shown that in the emotional labor of social workers, surface behavior had a negative effect on job performance, and inner action had a positive effect on job performance. Second, in the emotional labor of social workers, it was found that the surface act had a positive effect on the support of the superior and co-worker, and the inner act had a negative effect on the support of the superior and co-worker. Third, the superior & co-worker support of social workers had a positive effect on job performance. Fourth, superior & co-worker support in the relation to surface behavior and job performance in the emotional labor of social workers had a negative mediated effect. Superior & co-worker support in relation to inner act and job performance had revealed that it did not have a mediated effect.

Purpose: This study identified the influence of hotel workers' emotional labor and social support on their intentions to change jobs. Methods: Study participants were 437 workers from seven hotels in Korea who consented to the survey. Among them, insufficient responses from 21 participants were excluded, as well as 107 responses from workers with workloads of under one hour of face to face work. Thus, 309 hotel workers were included in the final analysis. A multivariate regression analysis was used to identify factors influencing the hotel workers' intention to change jobs. Results: The intention to change jobs was high when external behavior was shown, and workers who received social support from a superior exhibited low intention of changing jobs. Conclusion: The study results show that the most influential variables of turnover intention are external behavior and the support of a superior. It is therefore important to educate managers on personnel management methods for reducing external behaviors so that the rate of job changes by hotel workers can be reduced. It is also necessary to prepare and manage measures for strengthening the support system by workplace superiors.

The Film-making industry in Korea has significantly expanded during last decade. However, the development didn't necessarily mean there's improvement in terms of the quality of life for the film staffs. In post-production stages, especially, any workers involved in the production can get tremendous amount of mental pressure and stress due to the deadline. Thus, in this period, most labor issues are found and often ignored. In this research, compared to Hollywood, Korean domestic film industry will be analyzed with focus on labor organizations. Their role will be explored and examined in terms of improving the qualify of life as well as of the film itself.

The archives should not document the absence of labor records, but document the traces of workers' lives. In other words, it is the responsibility of the archive to reproduce the acts and sufferings of contingent workers with records, and to reveal the oppressive structure of capitalism based on them. Records representing the lives of contingent workers, such as labor manuals, should be at the core of records that symbolize the present, and archives should be documented. The archives should discard the illusion of neutrality.
