  • Background: Many studies have reported noticeable increases in the proportion of employees working either relatively short or relatively long hours. Such trends have been accompanied by an increasing concern regarding work hour mismatches defined as a discrepancy between actual and preferred work hours. The aim of this study was to investigate association between work hour mismatch and depression. Methods: Data regarding work hour mismatches for 47,551 adults were extracted from the 2017 Korean Working Conditions Survey. The World Health Organization-Five Well-Being Index was used to measure depression. Multiple logistic regression analyses were performed to examine the association between work hour mismatch and depression. Results: Men and women workers with work hour mismatch were more likely to have depression [underemployed males: odds ratio (OR) = 1.30, 95% confidence interval (CI) = 1.14-1.49, overemployed males: OR = 1.28, 95% CI = 1.18-1.40; underemployed females: OR = 1.37, 95% CI = 1.20-1.56, overemployed females: OR = 1.12, 95% CI = 1.02-1.23]. Underemployed workers, workers who worked more than 52 hours per week, and workers with a high income level, all had higher ORs for depression. The greater the discrepancy between actual and preferred work hours, the higher OR for depression among both underemployed and overemployed workers. Conclusions: A difference between actual and preferred work hours was associated with depression. Underemployed workers had a higher risk of depression than that of overemployed workers. As a work hour mismatch negatively affected workers' mental health, it is important to reduce work hours mismatches as well as shorten the absolute number of work hours.

  • Korean domestic workers are trend to avoid harmful and dangerous jobs calls 3D work due to the poor working conditions. Therefore, the incoming population of foreign workers is increasing to fulfill the required labor force. Mostly these foreign workers are placed in small and medium-size industries. As work that induces musculoskeletal disorders(WMSD) is equally exposed to domestic workers as well as foreign workers, this study attempted to investigate the work burdened by musculoskeletal disorders and derive improvement measures by understanding the actual conditions of the worksites of foreign workers. The result of this investigation defines that the possibility of developing musculoskeletal disorders is very high in the environment in which more than 40% of the respondents work with heavy objects and repetitive work of wrists and elbows. To prevent the symptoms of musculoskeletal disorders among foreign workers, three measures were proposed. To reduce the mandatory check-up period of WMSD under the Occupational Safety and Health Act, to revise the employment permit system, and to enhance the practical help of EPS education. Safety and health management of foreign workers is becoming an essential task not only for securing a workforce but also for the national image. Personal and economic losses at the national level should be minimized through policy support such as financial support for small and medium-sized businesses in Korea and supplementation of legal systems for the protection of foreign workers.

  • This study used Korean work environment surveys data to confirm the relationship between exposure to harmful and risk factors and absenteeism of manufacturing workers according to the survey period. Accordingly, 8,318 workers in the manufacturing industry were analyzed for the same questions of harmful and risk factors in 2011 (3rd), 2017 (5th), and 2020 (6th). Work-related hazards and risks, vibration, noise, high temperature, dust inhalation, vapor inhalation, chemical handling, and infectious material handling were found to affect absenteeism more than 3/4 of the time of exposure in 2020 compared to 2011. In conclusion, it was found that non-exposure to work-related hazards and risk factors increased one survey after another, and that the time of exposure to work-related hazards and risk factors affected absenteeism.

  • Counterproductive work behaviors are behaviors by employees intended to harm their organization or organization members. Human is the being has a desire and behaviors. To understand behaviors of an individual, it is important to understand the personality which determines a difference between individuals. Narcissists has psychological traits to be likely to experience negative emotions, such as frustration, hostility or anger, and this psychological traits of narcissists are more likely to induce an aggression. In this view, the purpose of this study was to examine the relationships between counterproductive work behaviors and narcissistic personality characteristics and to explore psychological dynamics about how narcissistic personality characteristics had an effect on counterproductive work behaviors. As a result, facts known were as follows. First, narcissists has strong desires to maintain a sense of superiority over others and defend their egos against unpleasant evaluation information, even if the information is factual and accurate. Second, narcissists are hyper-sensitive to negative information and are more likely to encounter information or situations that challenge their positive self-appraisals by this view. Third, in response to these challenges, or ego threats, these individuals are more likely to experience negative emotions, such as anger, frustration, or hostility. Forth, this negative emotions lead to aggression and as a result, this is more likely to induce counterproductive work behaviors such as theft, sabotage, interpersonal aggression, work slowdowns, wasting time and materials, and spreading rumors. Thus, narcissism is another individual difference variable that may be an important factor in determining counterproductive work behaviors, particularly under conditions perceived to be difficult or stressful.

  • Objectives: The study was performed to investigate characteristics of hazardous factors regarding chemical(liquid lime) tank dredging workers by case survey. Methods: Field data such as working condition, MSDS and respirators applied to chemical tank dredging work were analyzed and the work environmental factors of noise and indoor air quality were measured to compare existing data with actual work situations. Results: No health hazards to workers due to working conditions were confirmed during dredging work inside the chemical storage tank. All air quality measurement data during dredging work satisfied the management standards, and there were no by-products. During dredging work, there was a significant change in noise depending on the type of work, but considering the noise reduction rate(NRR) of the earplugs worn by workers, there was no actual health hazard due to noise exposure. Conclusions: A fit test for respirator and the expiration date of the safety helmet should be observed to ensure an appropriate level of safety and health for dredging workers in the chemical storage tank.

  • A questionnaire survey of farmers engaged in actual farming was conducted to investigate the farmers' actual wearing conditions and preferences for agricultural workwear to develop workwear that is suitable for improved agricultural work efficiency. We extracted basic data necessary for the development of agricultural workwear. Analysis of the photographs taken showed differences in the shoes and gloves worn depending on the type of work. The percentages of men and women were equal among the agricultural workers. The age of the agricultural workers was analyzed and the results showed a higher percentage of those over 50 years old, indicating that the age of the agricultural workers was higher than in other industries. It was found that the waist, knees, and elbows of the workers were pulled during work, and analysis showed that the symptoms resulting from clothing pulling were more severe when the wearing dimensions were larger. It was recognized that the important aspects of workwear are those related to work, such as functionality, activity, and work efficiency. In addition to workwear, the most commonly worn auxiliary equipment was gloves, and other items included hats, armbands, work shoes, boots, seat chairs, and masks. When developing rural workwear, it is necessary to consider the fit, type of work, and materials of the workwear. Future research should focus on materials that can improve the functionality of workwear and pattern development that reflects physical and movement characteristics.

  • In general, earth retaining work in construction works enables the construction of structures, prevents the displacement of the surrounding ground to the maximum extent, and plays an important role in ensuring the safety of the surrounding structures and field workers. The earth retaining work and the construction method differ according to the various ground characteristics, surrounding topographical characteristics, repair environment, and design conditions. In particular, in the case of Seoul city, the environments and ground conditions differ according to the area. This study analyzed the earth retaining work cost mainly for the apartment construction project in Seoul and calculated the approximate earth retaining work cost at the project planning stage. A model was developed to predict the cost of earth retaining work that matches the characteristics of Seoul City and predict the construction cost for earth retaining work. This paper presents the predicted earth retaining work cost using a multiple regression model that applies 10 project outlines as independent variables. The error rate of the prediction result of the earth retaining work cost of the apartment construction project in Seoul using multiple regression models was 10.75%.

  • With signs of the redevelopment of the domestic sewing industry, national support agencies were established. This study aims to assess the present conditions of the domestic sewing industry and investigate the effectiveness of national sewing industry support policies. According to the results of a survey of 30 sewing companies managers, the biggest factor causing product defects was work being rushed because of tight delivery dates, and the reduction in sales was caused by a lack of orders. Moreover, sewing technicians are aging, and the biggest reason for their decrease in number is that people do not pursue the job because of the common understanding that it is difficult. Managers perceived that the government's sewing technician training program was not a practical help. They were well aware of the support program to improve the work environment and the sewing equipment support program and showed high satisfaction with these programs, but they complained that the period for equipment rental was fixed. A majority of them thought that the Korean sewing industry environment had still not improved, and were skeptical about its future outlook. They identified its most urgent needs as the expansion of orders and the securing of manpower. The support programs that they wanted urgently included support for employees' four major public insurances and the enactment of the increase of toll processing fees.
