This paper suggests a new method for team-based learning which is focusing on the individual job assignment to solve the possible problems of free riders, dysfunctional conflicts, and hostility among students. Especially, it examines that if a method using job assignment could reduce the adverse effects of peer evaluation. This study was executed during one semester. Each team was organized with seven members and an independent job among seven different jobs was assigned to each member. At the end of the semester, it was examined that if individual job assignment had solved the possible problems of free riders, dysfunctional conflicts, and hostility among students. Finally, this study found that a new method of team-based learning using a job assignment lessened a problem of free riders, and reduced dysfunctional conflicts and hostility among students comparing with the peer evaluation method. The suggested method in this paper, which focuses on the job assignment of team project, could improve the efficiency of team-based learning in education course.

Kim(2011) showed that the team-based teaching method which is focusing on the individual job assignment solves the backlash effects of peer-evaluation method and suggested that it should be studied if the job assignment teaching method does not worsen the learning outcomes[1]. To analyse the learning outcomes of the job assignment teaching method is the purpose of this paper. This paper evaluates the improvement of the learning outcomes which are resulted from a variance of education style that each member of project team was given his specific task. Firstly, all the students evaluate a learning satisfaction and quality of outcomes by themselves. Secondly, an instructor and some professionals evaluate all the outputs. The results showed that the learning outcomes evaluated by students and instructors are improved significantly. The suggested method in this paper, which focuses on the job assignment of team project, could improve the learning outcomes of team project in engineering education.

Purpose: The purpose of this study was to investigate the effects of firefighters' job stress and emotional labor on their turnover intention, and analyze the main factors impacting turnover intention in this context. Methods: Based on a descriptive survey study design, we administered a structured questionnaire among 231 firefighters at one fire station in G metropolitan city from November 13 to 27, 2020. Results: Regarding job stress, participants showed differences based on marital status (p<.05), health status (p<.001), total service period (p<.05), and assignment (p<.05). For emotional labor, a significantly higher rate was observed for female than male firefighters (p<.05), with differences also observed in age (p<.001), health status (p<.001), total service period (p<.05), rank (p<.001), and assignment (p<.05). Further, for turnover intention, significant differences were noted with respect to age (p<.001), education (p<.01), health status (p<.001), total service period (p<.01), work unit (p<.05), rank (p<.001), and assignment (p<.05). A significant correlation was found between job stress and emotional labor and turnover intention. Regarding the factors affecting turnover intention, significant differences were noted based on education, rank, job stress, and emotional labor; the explanatory power was 53.9% (F=13.806, p<.001). Conclusion: Tailored support programs must be developed to ease firefighters' job stress and reduce their emotional labor to facilitate effective manpower management and reduce firefighters' turnover intention.

Consider a job shop that is modelled as an open queueing network of the Jackson(l957) type. All work stations in the shop have the same number of parallel servers. Two problems are studied : the loading of stations and the assignment of servers, which are represented by loading and assingment vectors, respectively. Ma jorization and arrangement orderings are established to order, respectively, the loading and the assignment vectors. It is shown that reducing the loading vector under ma jorizat ion or increasing the assignment vector under arrangement ordering will reduce the congestion in the shop in terms of reducing the total number of jobs(in the sense of likelihood ratio ordering), the maximum queue length(in the sense of stochastic ordering), and the queue-length vector( in the sense of stochastic majorization). The results can be used to supprot production planning in certain job shops, and to aid the desing of storage capacity.

FMS operating system consists of several subsystems in general. i.e. tool grouping subsystem. tool/job assignment subsystem. job dispatching subsystem, and papers dealing with each subsystem were published by many researchers [1], [4], [6], [8], [9], [10], [11], [12], [13], [14], [15], [16]. This paper mainly discusses about tool/job assignment subsystem as a job loading procedure. that occupies the kernel position of overall FMS operating system. Its performance is evaluated through simulation experiments of an integrated operating system under a typical FMS hardware configuration implemented in many machining factories, which is composed of the proposed procedure as well as a job dispatching procedure including several heuristic dispatching rules in terms of rule-base.

Purpose: The purpose of this study was to describe role conflict and job satisfaction of Neurosurgery Clinical Nurse Specialist(NCNS) and to identify associated factors. Method: The target populations was 77 NCNSs from 30 general hospitals. Data were collected with self-administered questionnaires and analyzed using t-test and ANOVA. Results: The overall mean scores of role conflict and job satisfaction were $3.60({\pm}0.54)$ and $3.04({\pm}0.46)$ respectively. Significant variables affecting role conflict were the working period as NCNS, the number of colleague NCNSs in working hospital, and assignment of prescription rights. The significant variable affecting job satisfaction was assignment of prescription rights. There was no statistically significant correlation between job and role conflict. Conclusion: The variable effecting both role conflict and job satisfaction was the extent of prescription rights. In order to improve the quality of patient care and to protect Neurosurgery Nurse Clinical Specialist, the enactment of law on prescription practice is needed.

For the scheduling and the job assignment of the ship hull production design which is a process-based work, we suggest the simulation-based scheduling using the discrete-event-based business process simulation. First, we analyze the ship hull production design process from the perspective of a job assignment to make it into the simulation model using DEVS (Discrete Event System Specification) which is the representative modeling method for a discrete-event simulation. Based on the APIs of the open-source discrete-event simulation engine, we implement the simulation using the Groovy script. We develop the scenario generator in which the user defines detail information of the construction drawing and its member blocks, and design engineers information, and the various setting for the simulation including the job assignment strategy. We use the XML files from this scenario generator as inputs of simulation so that we can get simulation result in forms of Gantt chart without changes of the simulation model.

We suggest a distributed framework for task assignment in the computer-controlled shop floor where each of the resource agents and part agents acts like an independent profit maker. The job allocation problem is formulated as a linear programming problem. The LP formulation is analyzed to provide a rationale for the distributed task assignment procedure. We suggest an auction based negotiation procedure including a price-based bid construction and a price revising mechanism. The performance of the suggested procedure is compared with those of an LP formulation and conventional dispatching procedures by simulation experiments.

This paper considers common due-date assignment and scheduling on parallel machines. The main decisions are: (a) deter-mining the common due-date; (b) allocating jobs to machines; and (c) sequencing the jobs assigned to each machine. The objective is to minimize the sum of the penalties associated with common due-date assignment, earliness and tardiness. As an extension of the existing studies on the problem, we consider sequence-dependent setup times that depend on the type of job just completed and on the job to be processed. The sequence-dependent setups, commonly found in various manufacturing systems, make the problem much more complicated. To represent the problem more clearly, a mixed integer programming model is suggested, and due to the complexity of the problem, two heuristics, one with individual sequence-dependent setup times and the other with aggregated sequence-dependent setup times, are suggested after analyzing the characteristics of the problem. Computational experiments were done on a number of test instances and the results are reported.
