  • In the Cloud, for the scheduling of parallel jobs, there are many tasks in a job and those tasks are executed concurrently on different VMs (Visual machines), where each task of the job will be executed synchronously. The goal of scheduling is to reduce the execution time and to keep the fairness between jobs to prevent some jobs from waiting more time than others. We propose a Cloud model which has multiple Clouds, and under this model, jobs are in different lists according to the waiting time of the jobs and every job has different parallelism. At the same time, a new method-ZOMT (the scheduling parallel tasks based on ZERO-ONE scheduling with multiple targets) is proposed to solve the problem of scheduling parallel jobs in the Cloud. Simulations of ZOMT, AFCFS (Adapted First Come First Served), LJFS (Largest Job First Served) and Fair are executed to test the performance of those methods. Metrics about the waiting time, and response time are used to test the performance of ZOMT. The simulation results have shown that ZOMT not only reduces waiting time and response time, but also provides fairness to jobs.

Their working business are shown as manufacturing area of broadcasting & telecommunication, telecommunication service, science/technology service, and media service. As for the value of qualification, the current working business area of respondents is more influential factor than the types of qualification. Workers of media service industry recognize the qualifications more useful in job-getting and job performance.

  • The purpose of this study is to find out the factors that have an effect on students, especially in the natural science track, would enter the college of Engineering. For this, the data of KEEP was used, and logistic regression was utilized for analyzing this data. The dependent variables are 'Entering the college of engineering' and 'No entering the college of engineering'. The probable independent variables are 'Sex', 'Interest in mathematics', 'mathematics study achievement', 'Interest in Science', 'Science study achievement', 'The area of book that is read', 'The area of club', 'Knowing about working environment and task of the job' and 'Knowing about prospect and wage of the job'. The results are as follows. These are 'Sex', 'Knowing about working environment and task of the job', 'Knowing about prospect and wage of the job' that affect statistically entering the college of engineering. In other words, the male student who know working environment, task, prospect and wage of the job well may enter the college of Engineering.

  • Logistics industry is being an important industry in Vietnam with the contribution from 8-10% of GDP recently. This industry employs about 15 millions people. Increasing the employees' job satisfaction is become one of the most concerns of managers in logistics companies to strengthen the employee engagement and improve their business performance. The aim of this study is to investigate how employees' perceptions of job satisfaction are influenced by factors such as job stress, leadership capability, work-life balance, and demographics. 426 workers in the logistics sector in Vietnam were surveyed online. The acquired data was analyzed using a structural equation model. In total 16 hypotheses were established, 13 of which were deemed to be significant. The results demonstrate how the literature-informed second-order constructs can potentially explain the overall job stress, leadership capability, and work-life balance of employees in the Vietnamese logistics industry. These variables account for 54.8% of job satisfaction. This study makes a theoretical contribution to the extant literature by showing how researching second-order constructs can improve the theory's capacity to predict employees' job satisfaction. The paper concludes with a set of recommendations for the management of logistics firms in Vietnam.

  • This study is aimed at analyzing the relationship between personal factors of radiological technologists and their job stressors. For this aim, a survey was conducted by means of 890 questionnaires from the middle of July to the end of August 2003 to the subjects of radiological technologists who are working for 44 general hospitals in 16 cities and provinces across the country. The results of the survey could be summed up as follows: 1. The biggest stressor that affects a radiological technologist personally under the working situation turned out to be position, job satisfaction and physical symptom(p<0.001), while job satisfaction and physical symptom also played an important role in personal relationship(p<0.001). 2. In terms of job conflicts, colleagues, immediate seniors, job satisfaction and physical symptoms appeared to exercise great impact(p<0.001), As for job autonomy, age, position and job satisfaction were known to be heavily influential(p<0.001). 3. With regard to job load, job satisfaction and behavioral symptom turned out to have great influence while, in job stability, position and job satisfaction seemed to be immensely influential(p<0.001). The present study has a limit in that it covers only radiological technologists who are working at the 3rd reference hospitals but excludes those who are working at the first and second reference hospitals. The findings, however, are surely believed to be able to serve as basic data to improve the medical service quality as they will help reduce the stressors of and enhance mental and physical health for radiological technologists who play important roles as teammates with expertise in the medical field. These outcomes could also be referred to in future studies in this area.

  • Purpose: This article focuses on exploring the associations between job satisfaction, organizational commitment, and turnover intention. Specifically, this study estimates the impacts of Vietnamese employees' job satisfaction on their organizational commitment and turnover intention in FDI enterprises. Research design, data and methodology: The measures are adapted from previous studies to develop a questionnaire with a seven-point Likert scale. The dataset is directly collected from 227 respondents who are employees at FDI enterprises situated in the North of Vietnam. The dataset is analyzed by quantitative approaches using SPSS 24.0 and AMOS 24.0. Results: The results show that while turnover intention is positively correlated with monthly income, it is negatively correlated with job satisfaction and organizational commitment. Also, organizational commitment is positively associated with job satisfaction among employees at FDI enterprises in Vietnam. Conclusions: The findings of this study will serve as useful references for administrators of FDI enterprises and policymakers to promote employees' job satisfaction and retain skilled employees.
