This study investigated the effects of overtime work on the health-related quality of life (HRQoL) of Korean blue-collar workers. This cross-sectional study collected data on 229 Korean blue-collar workers in six small-sized companies from October to November 2015. The data were analyzed using hierarchical multiple regression analysis to estimate the effect of overtime work while considering convergence variables. In the hierarchical regression model, when overtime work variable was included in the model, $R^2$ change was statistically significant. The significant predictors for HRQoL were overtime work (${\beta}=.152$, p=.025), depression (${\beta}=-.192$, p=.003) and night shift work (${\beta}=-.201$, p=.032). The results of this study provide a basic data for establishing optimal working hours standards for improving the quality of life of Korean blue-collar workers.

The purpose of this study is to analyze the domestic travel activities by job characteristic and derive implications to improve the domestic tourism by using 2010 Korea National Tourism Survey data(Ministry of Culture, Sports and Tourism). We classified survey samples(1,813 persons) by 6 job characteristic categories and compared the domestic travel activities(number of travel, day of travel, expenditure of travel). As the results of analysis, the domestic travel activities of paid worker, full-time worker, employers with a 500 or more workers, biweekly five-day worker are more than non-paid worker, part-time worker, employers with a 10 or less workers, worker who work six to seven days a week.

The purpose of this study was to analyze the effect of mediating variables on the relationship between job stress and stress response. A survey was conducted to 243 clinical dental hygienists from January 15, 2013 to March 20, 2013 and the data were analyzed using t-test, one-way ANOVA, Pearson's correlation analysis, and hierarchical multiple regression analysis. The subjects who worked in poor working environment, had high level of role conflict and overload and aggressive nature showed high stress responsivity (p<0.01). The variable that showed mediation effect on the relationship between job stress and physical discomfort, depression was shown to be personality type (p<0.05). Also, the variable that showed mediation effect on the relationship between job stress and turnover intention was social support (p<0.05). According to the results, personality type and social support were shown to be important parameters when it came to the relationship between job stress and stress response. Therefore, in order to reduce negative outcomes caused by stress, it is suggested to provide an educational opportunity on self-control management while increasing social support from the organizational and structural level. Especially, it is asked to expand the system that provides encouragement and recognition to feel the sense of achievement in the course of their duty execution.

The factors influencing nicotine dependence of smoking shift workers (154 samples), working in manufacturing industry, were investigated. 23.4% of the sample showed moderate nicotine dependence while 14.3% did severe dependence. Nicotine dependence showed statistically significant difference with respect to sex, disease, and health condition and was positively correlated with occupational stress. Occupational stress, sex, and disease were identified as the influential factors, explaining 43.9%, and should be the basis for intervention to reduce nicotine dependence.

The aim of this study was to identify the influences of sleep quality, depression and fatigue on job stress of geriatric hospital workers. The subjects were 175 workers from 6 geriatric hospitals. Data were collected on March, 2015 using a structured questionnaire. The data were analyzed by using SPSS/WIN 21.0 program. The job stress was negatively correlated with sleep quality(r=-.364, p<.001), positively correlated with depression(r=.376, p<.001) and fatigue(r=.646, p<.001). The multiple regression analysis revealed that the most powerful predictor of job stress was fatigue(${\beta}=.581$, p<.001). These results indicate that fatigue affect job stress of the geriatric hospital workers. Therefore, it is necessary to prepare tailored fatigue management program and working conditions that can reduce job stress.

In a recent investigation of mental health professionals, since the reported rate about turnover intention was 54.5%, immediate management for related specialists is requested. This study attempted to validate the mediating effect of positive psychological capital in the process that job stress of mental health facility workers regulates turnover intention. A questionnaire survey on work stress, turnover intention, and positive psychological capital was conducted for 250 participants among mental healthcare staffs in Gwangju Metropolitan City and Jeollanam-do. Analyses were conducted to identify mediation effects and significance using with SPSS 21.0. As a result, job stress of workers in mental health facilities showed a significant positive (+) correlation with turnover intention. Second, we confirmed that positive psychological capital such as anticipation and optimism has a considerable mediating effect in the job stress and turnover intention of employees in mental health facilities, respectively. Based on statistic analysis, limitations on this study and suggestions for further studies were discussed.

Purpose: This study examined the factors influencing Nutrition Quotient for adults (NQ-A), focusing on workers in the manufacturing industry. Methods: The participants were 738 industrial workers in Gwangju. Their dietary information was analyzed using a questionnaire of NQ-A, which consisted of 21 checklist items and the general characteristics of the subjects. The scores of NQ-A and its 4 factors (balance, moderation, diversity, and dietary behavior) were calculated according to the general characteristics of subjects. The data were analyzed using a χ² test, t-test, correlation, and multiple regression using SPSS 21.0 program. Results: The mean NQ-A score was 45.3 for the total subjects, indicating a low grade. Non-shift workers showed significantly higher scores for balance, diversity, and moderation factors than shift workers. Forty-three (8.7%) shift workers and 123 (50.8%) non-shift workers had good NQ-A scores, whereas 453 (91.3%) shift workers and 119 (49.2%) non-shift workers required monitoring for nutrition. The significant influencing factors of NQ-A were the working pattern (p < 0.001), gender (p < 0.001), family composition (p < 0.001), age (p < 0.001), and household income (p < 0.001). As a result of multiple regression analysis, there was a significant difference in the NQ-A score for moderation (F = 141.930, p < 0.001), diversity (F = 98.998, p < 0.001), balance (F = 52.329, p < 0.001), and dietary behavior (F = 12.895, p < 0.001). As a result, shift work and gender had the greatest influence on the balance (β = -0.372, p < 0.001), diversity (β = -0.316, p < 0.001), and moderation (β = -0.507, p < 0.001) factors in NQ-A. Gender had the most influence on the dietary behavior in NQ-A. Conclusion: Shift work and gender were significant factors affecting NQ-A. To manage workers' health better, it will be necessary to prepare a nutrition education program according to the type of working pattern and gender.

Seasickness not only makes persons on board vessels to vomit but also causes vertigo, headache, sleepiness, fatigue, lethargy and other discomforts. This ailment leads to disturbance of biorhythm and decline of perception which would eventually cause reduction of situational awareness among ship's operators that leads to marine accident. This study is about the sensitivity of people onboard ships to seasickness and focused on deck or navigation officer cadets(apprentice officers) and engine officer cadets(apprentice engineers) who have no previous experiences on board. It is conducted by using motion sensor that can measure ship's X, Y, Z-axis motions and through the questionnaire survey, and evaluated each students' degree of seasickness symptoms. Through this study, in same circumstance, we have known that there are different degrees of motion sickness for wheel house worker and engine room worker, It also confirmed that seasickness have high relationship with degree of hull motion and also, with cycle of hull motion. In addition, we have confirmed that Z-axis hull movement has higher relationship with seasickness than X-axis and Y-axis hull movements. This study aims to initiate additional researches about X-axis and Y-axis of the ship's motion which it expects to greatly enhance safety of wheelhouse and engine room personnel, ship's livability and comfortable sailing.
