Objectives: Working at other times than the regular day shift has been reported to be a stressor associated with health consequences and mental disorders as well as disturbance of sleep. In current study, we aimed at investigating the relationship between work schedule, sleep quality and depression among police officers. Methods: Eleven hundreds and forty five police officers (male: 1040, female: 105) completed questionnaires of basic socio-demographic data, Pittsburgh Sleep Quality Index (PSQI), Korean Scale of Occupational Stress (KOSS), Impact of Event Scale - Revised (IES-R) and Center for Epidemiologic Study-Depression (CES-D). Results: After controlling for age, sex and educational level, score of CES-D was correlated positively with the score of KOSS, PSQI and IES-R on partial correlation analysis (r=-0.077; p=0.009, r=0.262; p<0.000 and r=0.421, p<0.000, respectively). Logistic regression analysis revealed that female sex, age, the score of KOSS and IES-R and schedule of rotating shift work predicted higher score than 16 score of CES-D significantly in total subjects (p=0.023, p=0.015, p=0.000, p=0.000 and p=0.022, respectively). Conclusion: Current result suggested that not only female sex, age, higher occupational stress and impact of event scale but also rotating shift work schedule might be related to depression among police officers.

This study conducted a survey of 315 facility security workers in Daejeon, South Chungcheong Province and Gyeonggi Province for about a week from August 7 to August 13, 2019 to identify the impact of work environment and job stress on job satisfaction, and finally collected 293 of the total 315 parts of the data, excluding non-response and inappropriate responses. The STATA 14.2 Statistical Package Program was used for analysis of the collected data, frequency analysis was performed to determine the distribution ratio of the subjects, and reliability analysis and correlation analysis were performed with respect to the established key variables. Next, t-test and one-way ANOVA were conducted to verify differences in work environment, task stress and task satisfaction factors according to demographic characteristics, and the results were as follows: There were differences in work environment, job stress and job satisfaction recognition depending on demographic characteristics. In detail, the factors for the work environment indicated significant differences in age, academic background, number of years of service, wages and types of service in the recognition of the work environment. Job stress factors indicated significant differences in age, education, wages and types of service in job stress recognition. In job satisfaction factors, age, academic background, number of years of service and wages (monthly benefits) showed significant differences in job satisfaction recognition. In addition, the results of multiple regression analyses to identify the working environment, job stress, and job satisfaction are as follows. The working environment has had a positive impact on job satisfaction, and the better the job environment, promotion and organizational characteristics, the higher the job satisfaction. It has been shown that job stress has had a negative impact on job satisfaction, conflict of relationship (promoting colleagues). job autonomy increases job satisfaction, and job satisfaction decreases when job requirements and job insecurity increase. In terms of the impact of work environment on job satisfaction, the higher the work promotion, job environment and organizational characteristics, the higher the job satisfaction level, the report showed. According to these studies, the better the working environment, the lower the job stress, and the lower the job stress, the higher the job satisfaction. In addition, the better the working environment, the more satisfied the job was found to be, and the empirical research result was verified that improvement of the working environment of security workers can reduce job stress and improve job satisfaction through improvement of the working environment.

Previous studies related to drinking problems among Korean employees has focused on not 'drinking on the job' but 'drinking off the job'. Thus, little is known about the relationships between 'drinking on the job' and work performance among employees in Korea. The purpose of this study is to examine the relationships between alcohol use including 'drinking on the job' and 'drinking off the job' and work performance among 577 employees working at the health or welfare related agencies in N-gu of Seoul. Analyses were conducted using univariate analyses and multiple regression to examine which alcohol use factors were associated with work performance among employees. As for alcohol use, 49.3% of participants reported 'drinking on the job' in the past 30 days and 48.2% of participants reported 'drinking in a company dinner' in the past 30 days. Univariate analyses on the relationships between alcohol use including 'drinking on the job' and 'drinking off the job' and 'work performance' showed' drinking on the job' was associated with all work performance items except 'being absent' and 'being hurted' were not associated with work performance. Meanwhile, 'drinking off the job' was related to only 'did not do the job well'. Multiple regression analyses demonstrated that gender, subjective health status, service period, and 'drinking on the job'. These findings suggested that there is a need to more concerns about 'drinking on the job', especially 'drinking in a company dinner' among employees in Korea.

This study analyzed 2019 time survey data from the National Statistical Office to examine the childcare behaviors of fathers with preschool children and their determinants, considering types of care and working/nonworking days. The main results of this study are as follows. First, paternal childcare time of nonworking days was three times more than that of working days, and the participation rate was also higher on nonworking days. Second, there was no significant difference in the amount of time spent on primary care and developmental care by fathers, whether from dual- or single-income families. Third, it seems that fathers adjust their participation in childcare between working days and nonworking days in consideration of the mother's time availability. Fourth, the variables related to childcare needs had a significant influence on paternal childcare time on both working and nonworking days. Fathers' developmental care time was not explained by the independent variables entered into the regression analysis. As a result of the study, it is necessary to reduce fathers' working hours and increase family-friendly systems to increase fathers' participation in childrearing. Fathers' perception of parental responsibility must also be changed.

The working-day movement model, which implemented in the ONE simulator, supports the environments similar to the real life by using the transportation. However, there is no taxi movement model in the working-day movement model. So, we implemented a taxi movement model in the ONE simulator as the previous work. It is changed significantly for the simulation results of routing protocols in the ONE simulator. In this paper, we analyze the performance evaluation of the DTN routing protocol such as an epidemic routing protocol using our taxi movement model in the ONE simulator.

The aim of this study was to investigate the level of depression among female hospital nurses and the influence of rotating shift work and quality of sleep on depression. A total of 295 nurses in Seoul were recruited and the data were analyzed using descriptive statistics and multiple regression analysis. The number of depressed nurses was 71.2%(CES-D total score ≥ 16) and factors influenced on nurses' depression were quality of sleep, rotating shift work, and work experience in nursing(1-2.9 years, more than 10 years). Based on the result of this study, nurse managers and hospital organization should use appropriate interventions to improve quality of sleep and negative effects of rotating shift work for nurses.

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.

This paper presents a mixed linear and integer goal programming (GP) model to aid in strategic planning and scheduling of guard soldiers. The proposed model is a general-purpose model, hence can be used to produce an optimal schedule with respect to any user-provided combination of guard post objectives and soldier preferences. We extensively test the usefulness of the model on a real-life dataset from a guard post in the ROK Army with using three objectives set by the guard post and three preferences provided by individual solders. Numerical results and analysis from these experiments show that the proposed guard scheduling model efficiently as well as effectively generates an optimal guard schedule and can also be used for an optimal revision of any existing schedule. In summary, these illustrate that the proposed model can be practically used for optimal planning and scheduling of guard soldiers in guard posts.
