  • This paper presents possibilistic job scheduling based on the membership function as an alternative to probabilistic job scheduling and illustrates a methodology for solving job sequencing problem which the opinions of experts greatly disagree in each processing time. Triangular fuzzy numbers are used to represent the processing times of experts. Here, the comparison method is based on the dominance property. The criteria for dominance are presented. By the dominance criteria, for each job, a mojor TFN and a minor TFN are selected and apessimistic sequence with mojor TFNs and an optimistic sequence with minor TFNs are computed. The three-machine flow shop problem is considered as an example to illustrate the approach.

  • This paper aims to evaluate the effects of Critical work factors on Work Motivation and Job Satisfaction of young Vietnamese employees. The four most essential work aspects were consisting of the Work environment, Employee empowerment, Salary, and Promotion opportunities. To empirically evaluate the proposed research model, the authors assemble data through conducting questionnaire interviews with young employees working in Vietnamese firms. A sample of 216 respondents was constructed using the PLS-SEM program to highlight the testing of thirteen hypotheses. The testing results indicate that four Critical work factors positively impact the job motivation of young employees, especially two factors as Salary and Promotion opportunities. Surprisingly, the hypothesis regarding the positive direct relationship between Promotion opportunities and Job satisfaction is not supported. Meanwhile, the rest influence factors have a significant connection with the Vietnamese worker's job satisfaction. The mediation role of Work motivation was also tested by examining the indirect positive relationship between four Critical work factors and Job satisfaction. This paper is the first study that focuses on young employees; hence, these research findings provide Vietnamese human resource managers some suggestions for reference, which can be considered the dynamic factors on the young Vietnamese employees.

  • Purpose: In this study, we would like to confirm that the transfer of young workers may be a means of enhancing their internal satisfaction, not to get a better job, by setting work-related characteristics that are highly relevant to job-related factors. Research design, data, and methodology: In this study, preparation for turnover was set as dependent variables to identify factors related to the turnover of young people, and the type of business, employment type, debt status, job satisfaction, job difficulty compared to education level, job difficulty, job degree, job major agreement, debt status, and other demographic social characteristics were selected as independent variables. Results: The characteristics related to personal criteria in job-seeking process were significant in the form of business, employment type, job satisfaction, work difficulty compared to the level of education, work difficulty compared to the level of technology, job major matching, and debt status. Conclusions: This study confirmed that young people's turnover may not simply be a means to get a better job, but to increase satisfaction in the internal aspects of their jobs, and that for young people, a job is an important development process that represents their identity and needs to be approached from a life-cycle perspective.

  • The purpose of this study was to understand effects of culinary staff's technology kitchen system upon perceived ease of use, usefulness, attitude, and job performance in the foodservice industry. Based on a total of 387 samples obtained from empirical research, this study reviewed the reliability and fitness of the research model and verified a total of four hypotheses using the Amos program. The hypothesized relationships in the model were tested simultaneously using a structural equation model (SEM). The proposed model provided an adequate fit to the data, ${\chi}^2$=226.501 (df=85), p<.001, CMIN/df 2.665, RMR .066, GFI .927, NFI .926, IFI .952, TLI .941, CFI .952. The results show that culinary staff's perceived ease of use(${\beta}$=.534) had a significant positive effect on perceived usefulness. Also, perceived ease of use (${\beta}$=.350) and perceived usefulness (${\beta}$=.297) had a positive significant effect on attitude. Further, attitude (${\beta}$=1.647) had a significant positive effect on job performance. Limitations and future research directions are also discussed.

  • The effects of particle sizes (small, medium and large sizes) and gelatinization treatment on the changes of the instant properties of Job's tears powder were investigated. The degree of gelatinization on the different particle size samples of Job's tears powder was the highest in the small particle size, and it also showed an increasing trend regardless of pregelatinizing whether it is or not as the particle size decreased from large particle size to small particle size. The water solubility index of the pregelatinized samples was high compared to that of ungelatinized samples regardless of particle size and temperatures. The water absorption and swelling power increased as particle size and temperature were increased. The dispersibility and sinkability of ungelatinized sample was increased as particle size and temperature were increased and it also showed lower value regardless of particle size and temperature. However, the dispersibility and sinkability of pregelatinized samples were shown to have the opposite result, such that the smallest particle size of pregelatinized sample had the lowest sinkability (11.3%). The turbidity of the pregelatinized small particle size was the highest by a factor of 1.08.

  • The present study is designed to develop surveying tools to measure stressors of and social supports for Radiological Technologists which may play a role to alleviate their stresses caused from their job environments. For this purpose, an analysis of reliability by factors of personal stressors was conducted on 890 radiologists who are working at 44 general hospitals in 16 cities and provinces across the country. The results of the analysis may be summed up as follows: Six factors in 2 concerned fields turned out to be major tools for use as items of questionnaires to measure social supports for and organizational culture of Radiological Technologists. The factors determined to be applicable for survey with reliability coefficient of more than 0.7 measured by factors for internal coherence included social supports on the job(0.90), off-the-job social supports(0.81), job satisfaction(0.80), devotion for job by length of service(0.81) and emotional devotion for job(0.80), all deemed to be appropriate as survey items. In the verifying process of the results, it was found that normative devotion for job(0.61) showed lower reliability as its statistical coefficient was analyzed to be less than 0.7. It seemed, therefore, necessary to reconstruct items or re-select such ones only that can maintain internal coherence in order to analyze appropriateness of related measuring tools, or to develop new measuring tools. Although the outcomes of this study can be used to verify reliability and appropriateness of concerned concepts to assess stresses caused during the job performance of Radiological Technologists, it may be improper to adopt them to measure all types of social supports and stresses that occur generally under the job environment. It is desired, however, to compare and analyze the findings of the present study with others and to utilize them as basic data for further development of tools that can maintain internal coherence in terms of reliability and appropriateness in spite of changing social environments.
