In this paper, we propose a simple and relatively efficient heuristic method to determine job sequencing in the flow-shop considering multiple criteria such as processing time, due date and cost. The proposed method is applicable to the flow- shop where the jobs are released simultaneously and their processing sequence is predetermined and not changed until the whole jobs are processed. To develop this method, we mixed and modified some well-known multi-attribute decision heuristics such as the simple linear weighting scheme, the lexicographic rule and the 'elimination by aspect' rule. Some computer simulations were conducted to test the efficiency of the proposed method and it has been compared with the SWPT (Shortest Working Processing Time) rule and EDD (Earliest Due Date) rule. The results show that our method is as effective as the traditional ones in terms of mean flow time, tardiness, makespan, cycle time, machine utilization, etc., and proved to be much simpler and more flexible to be used in real situations.

In this paper, we considers the outsourcing decision problem in a single machine scheduling problem. The decision problem is to determine for each job whether to be processed on an in-house manufacturing or external facilities(outsourcing). Moreover, this paper considers a situation where each job has a due date. The objective of the problem is to minimize the outsourcing cost, subject to the due date constraints. The considered problem is proved to be NP-hard. Some solution properties and valid inequalities are derived, and an effective lower bound is derived based on the LP-relaxation. The results of experimental tests are presented to evaluate the performance of the suggested lower bound.

The use of human resources determines the success of enterprises. This study applies the questionnaire design method to analyze the relationship between job stress, job satisfaction, and job performance, noting that few studies have comparatively examined these variables between industries, especially between high-tech and traditional industries. The proposed assessment model in this study can facilitate decision-makers' ability to make the optimal business decisions through their personnel systems, thereby improving employee satisfaction and increasing job performance. This study found that in the traditional and high-tech industries, some demographic variables have significant differences in the job stress, job satisfaction and job performance, but the demographic variables that can significantly affect the differences in these job's variables are differences between industries. This study acknowledges that job stress and performance have a significantly negative correlation, and traditional industries will have more stress factors than high-tech industries. In addition, support for traditional industries exist in job satisfaction and performance has a significantly positive correlation, but not in high-tech industries. Job stress for performance has a significantly negative correlation in two industries. This study reconfirmed the relationship between job stress, satisfaction and performance, found some differences in this relationship and the respective industrial characteristics.

Background: A job-specific Worker's Health Surveillance (WHS) for hospital physicians is a preventive occupational health strategy aiming at early detection of their diminished work-related health in order to improve or maintain physician's health and quality of care. This study addresses what steps should be taken to determine the content of a job-specific WHS for hospital physicians and outlines that content. Methods: Based on four questions, decision trees were developed for physical and psychological job demands and for biological, chemical, and physical exposures to decide whether or not to include work-related health effects related to occupational exposures or aspects of health reflecting insufficient job requirements. Information was gathered locally through self-reporting and systematic observations at the workplace and from evidence in international publications. Results: Information from the decision trees on the prevalence and impact of the health- or work-functioning effect led to inclusion of occupational exposures (e.g., biological agents, emotionally demanding situations), job requirements (e.g., sufficient vision, judging ability), or health effects (e.g., depressive symptoms, neck complaints). Additionally, following the Dutch guideline for occupational physicians and based on specific job demands, screening for cardiovascular diseases, work ability, drug use, and alcohol consumption was included. Targeted interventions were selected when a health or work functioning problem existed and were chosen based on evidence for effectiveness. Conclusion: The process of developing a job-specific WHS for hospital physicians was described and the content presented, which might serve as an example for other jobs. Before implementation, it must first be tested for feasibility and acceptability.

A cross-sectional study was conducted to assess the association between musculoskeletal workload and psychosocial job stress variables from 100 employees from a cable making industry. It was found that the employees who had to do musculoskeletal hazardous tasks suffered higher psychosocial stress in 'decision latitude', 'job insecurity' and 'psychological job demands' also. The employees with higher level of psychosocial job stress in 'psychological job demands' and 'score of the "type A" personality' responded that they had higher 'physical job demands' from the task irrespective of its musculoskeletal hazardousness. These results confirm that musculoskeletal workload were associated with both physical and psychosocial work factors. Attention should be paid to psychosocial work factors along with physical workload to prevent musculoskeletal disorders in the manufacturing industries.

Purpose: This study examined the association of job satisfaction and job stress with the self regulation of nurses. Method: This research was descriptive in its design and used a self-administered questionnaire. The study subjects were 173 nurses who worked in the three university teaching hospitals. The instruments used in the study were self-regulation scale, job satisfaction scale and job stress scale. The data were analyzed by ANOVA, t-test, Pearson Correlation Coefficient, and multiple regression. Results: The mean score of self regulation, job satisfaction and job stress were 4.58, 1.90 and 3.31, respectively. The degree of error and confidence in decision making of the study subjects was associated with the extent of job satisfaction and job stress. Conclusion: Self regulation made an influence in a statistically significant way on nurses' job satisfaction and job stress. Therefore, we need to develop strategies to enhance the self regulation of nurses to improve their job satisfaction and job stress in a positive way.

스마트폰의 등장으로 인해 언제 어디서나 정보를 누구라도 손쉽게 전달하고 볼 수 있는 시대가 되었다. 과거에는 개인적 홍보나 생각의 나눔을 위한 도구로서 SNS를 사용해 왔지만, 최근 SNS 사용자의 증가와 그 사용속도의 증가 추세에 따라 기업들이 팀의 협력이나 의사결정에 직접 스마트폰을 이용하여 의사결정의 질이나 업무성과를 제고하는 노력이 진행되고 있다. 이처럼 소셜 네트워크 사이트(SNS Social Networking Service)의 활성화는 이미 사람들이 인터넷 매체를 통해 즐거움과 같은 긍정적 경험을 많이 누리고 있음을 제시한다. 그러나 한국의 조직 구성원들을 대상으로 SNS가 구성원들의 업무성과에 미치는 긍정적인 기능에 대한 논의는 부족하였다. 이에 본 연구는 조직구성원들이 실제 SNS을 통한 참여를 통해 기업에서 SNS의 활용과 참여가 업무성과를 향상 시킬 수 있는지를 분석하고자 하였으며, 실제 이들의 영향관계에서 팀의 협력 및 의사결정의 질이 중요한 매개 역할을 하는지를 규명하고자 하였다. 연구의 결과는 SNS의 참여가 높을수록 업무성과에 긍정적인 영향을 미치고 있음을 알 수 있었고 이들의 인과관계에서 팀의 협력과 의사결정의 질이 중요한 매개작용을 하고 있음을 확인하였다. 본 연구의 결과들은 실제 구성원들의 업무성과 향상을 위해서는 직장인들의 사회적 네트워크의 활용도를 높여서 업무의 활용도를 높여야 한다는 시사점을 밝혀낼 수 있었다. 또한 SNS의 참여는 팀의 협력과 의사결정의 질도 높일 수 있는 요인임을 알 수 있었다.
