It can be made a definition that scheduling is a imposition of machinery and equipment to perform a collection of tasks. Ultimately scheduling is an assessment of taking order for which would be perform. So it is called "sequencing" in other words. In a job shop scheduling, the main object is to making delivery in accordance with the due date and order form customer, not to producing lots of quantity with minimizing mean flow time in a given time. Actually, in a company, they concentrate more in the delivery than minimizing the mean flow time. Therefore this paper suggest a new priority dispatching rule under consideration as below in a n/m job shop scheduling problem with due date. 1. handling/transportation time, 2. the size of customer order With this algorithm, we can make a scheduling for minimizing the tardiness of delivery which satisfy a goal of production.roduction.

In recent studies, construction industry workers with higher job stress and lower work ability were more likely to experience accidents at their workplace. Likewise, fatal accidents rate was higher among simple labor workers compared to technical workers. Therefore the evaluation of a worker's job stress and work ability seems to be important in preventing the occurrence of fatal accidents. To search for ways to reduce job stress and to improve work ability, the current study conducted a job stress analysis based on age, years of service, skill level, hobbies, sleep patterns, and monthly income. For this, the Korean occupational stress questionnaire short form and the Work Ability Index (WAI) developed by the Finnish Institute of Occupational Health (FIOH) were used. In this study, SPSS 12.0K statistics program was used for statistical analysis and significance was verified by the Kruskal-Wallis test and non-parametric tests. The results of this study can be summarized as follows : (1) Simple labor workers had higher job stress and less work ability than technical workers. (2) The more experienced workers had lower job stress and higher work ability. (3) In the case of workers who slept a lot, work ability was higher and job stress was less. (4) Monthly income influenced on the job stress and work ability. (5) Job stress and work ability in accordance with the age difference was not significant.

As the broadcasting system rapidly migrates to the HD contents production, a broadcasting professional training program has increasingly requested, which provides a professional ability keeping up with new demands and a systematic well-organized education program. This paper utilized a DACUM(developing a curriculum) method for a video editor's job analysis and presented a job model of video editing. With a DACUM job analysis, we retrieved 9 essential job duties and 71 tasks, and then examined their importance, difficulty, frequency, and entry level tasks that are required before job hire. We also established a well-form structure of the job analysis results, completed a DACUM research chart, and consequently built a video editor's job model in TV broadcasting and video production areas. The proposed model is expected to be used as a fundamental material for a future job organization of video editors in TV broadcasting and video production areas, a development of the educational curriculum, and a priority decision of on-the-job training programs.

This study was conducted to compare differences in dietary habits and snack consumption behaviors according to level of job stress among 20- to 30-year-old office workers. Subjects were 205 office workers working in companies located in Seoul and the metropolitan area. Self-administered questionnaires written by the subjects were statistically analyzed by the SPSS 20.0 program. Subjects were classified into a high-risk job stress group (n=102, High-RSG) or low-risk job stress group (n=103, Low-RSG) by level of job stress. For dietary habits, the duration of meal time before suffering from job stress in High-RSG was significantly faster compared to Low-RSG. Appetite after suffering from job stress in High-RSG was significantly higher compared to Low-RSG. For snack consumption behaviors, the reason for snack intake was 'job stress' for 42.2% in High-RSG and 'hunger' for 31.1% in Low-RSG (p<0.05). Energy intake in the form of chocolates, castellacakesmuffins, and flavored milk during working hours was significantly higher in High-RSG compared to Low-RSG (p<0.05). Therefore, this study suggests that dietary guidelines to ameliorate job stress should be developed in order to manage and improve dietary habits caused by suffering from job stress among young office workers at companies.

Objective : The aim of this study is to analyze the relationship among job stress, depression, and suicidal ideation in firefighters, particularly the mediating effects of depression. Methods : The subjects were 2,136 firefighters in Gangwon-do, who completed the short form of Korean occupational stress scale (KOSS-SF), Korean version of the Beck depression inventory (K-BDI), and the revised scale for suicide ideation (SSI) online in mental health promotion service of firefighters. The data was analyzed with correlation analysis among the variables, and the multiple regression analysis method of Bar-on and Kenny (1986) was used. Results : Job stress showed positive correlations with depression (r=0.493, p <0.01) and suicidal ideation (r=0.296, p<0.01). Depression showed a positive correlation with suicidal ideation (r=0.561, p<0.01). The result of analyzing the mediating effect of depression showed that depression was a full mediator variable between job stress and suicidal ideation. Conclusion : Based on the results, it is very likely that job stress may affect suicidal ideation via depression. These results suggested that the preventive interventions emphasized on depression may be helpful for reduction of suicide in firefighters.

Purpose: This study was done to investigate differences in health behaviors by job stress level in male and female workers in a large-sized company. Methods: Participants were 576 male and 228 female workers who completed questionnaires. Job stress was measured using the 'Short Form Korean Occupational Stress Scale (SF-KOSS)'. Health behaviors included smoking, alcohol consumption, regular exercise, and diet. Frequency, mean, SD, chi-square test, and multivariate logistic regression using SAS version 9.1 were used to analyze data. Results: Smoking, drinking and regular exercise rates were not different by job stress level in male or female workers. Only regular diet was significantly different by job stress level in male and female workers. From multivariate analysis, the alcohol consumption rates for female workers differed by marital status. Regular exercise rate was significantly related to age for male workers and type of employment for female workers. After adjusting for demographic and work-related characteristics, regular diet significantly differed by shift work for male workers and marital status and shift work for female workers. Conclusion: The findings of the study indicate that nursing interventions should be developed to manage job stress to improve diet habits for male and female workers in large-sized companies.

Propose: To identify the effects of job stress for depression in clinical nurses. Method: The subjects were 304 clinical nurses in Busan Metropolitan City. Data was collected by questionnaire surveys using convenience sampling. The instruments used in this study were the short form of the Korean Occupational Stress Scale(KOSS-SF) and the Beck Depression Inventory-Korean Version Standard Ten(K-BDI STEN). Result: After adjusting potential confounders, we found that the group of 50~75% job stress score for interpersonal conflict was more likely to have depression than the group of less than 25%(OR=3.522, 95% CI 1.06~20.25). The group of equal or more than 75% job stress score for job insecurity was more likely to have depression than the groups of less than 25%(OR=9.413, 95% CI 4.00~71.03). The groups of equal or more than 75% and 50~ 75% job stress score for lack of reward was more likely to have depression than the group of less than 25%, respectively(OR=19.302, 95% CI 2.50~244.25; OR=38.201, 95% CI=6.25~344.45). Conclusion: To prevent depression in clinical nurses, we need to intervene job stress for insufficient job control, interpersonal conflict, job insecurity and lack of reward.

Objective : Several recent studies determined the associations of job stress with depression and suicidal idea, but the association between the number of job stress components and depression remains unclear. In the present study, we investigated the associations of the number of components of job stress with depression and suicidal idea. Methods : We studied 194,226 participants who attended employee health screenings from January to December, 2014, and completely answered all the questionnaires, including the short form of Korean Occupational Stress Scale (KOSS), the Center for Epidemiologic Study-Depression (CES-D) and suicidal idea. The presence of clinical depressive symptoms was defined as a CES-D score of ${\geq}21$. The subjects in the highest quartile of each subscale of KOSS were considered as suffering from each component of job stress. Chisquare tests, t-tests and logistic regressions were performed to compare study outcomes between groups. Results : When we included all seven components of job stress, there was no significant association of the number of the components with depressive symptoms, or suicidal idea. However, the prevalence of depressive symptoms and suicidal idea was increased only in three occupational stress subscales including job demand, job insecurity and occupational climate. When we analyzed only these 3 components of job stress, the number of job stress subscales was significantly associated with depressive symptoms and suicidal idea, even after adjustment for sex and age. Conclusion : The number of components of occupational stress was associated with depressive symptoms and suicidal idea, only in the related components.
