  • Most of scheduling methods in the Grid only consider one special attribute of the resource or one aspect of QoS (Quality of Service) of the job. In this paper, we focus on the problem that how to consider two aspects simultaneously. Based on the requirements of the jobs and the attributes of the resources, jobs are categorized into three kinds: CPU-overload, memory-overload, and bandwidth-overload jobs. One job may belong to different kinds according to different attributes. We schedule the jobs in different categories in different orders, and then propose a scheduling method-MTS (multiple attributes scheduling method) to schedule Grid resources. Based on the comparisons between our method, Min-min, ASJS (Adaptive Scoring Job Scheduling), and MRS (Multi-dimensional Scheduling) show: (1) MTS reduces the execution time more than 15% to other methods, (2) MTS improves the number of the finished jobs before the deadlines of the jobs, and (3) MTS enhances the file size of transmitted files (input files and output files) and improves the number of the instructions of the finished jobs.

  • Ensuring occupational radiation exposure(ORE) as low as is reasonably achievable(ALARA) has been one of very important requirements in a nuclear power plant. It is well known that about 70 percent of occupational dose has incurred from maintenance jobs in the outage period. To reduce occupational dose effectively, the high-dose jobs in the outage period should be identified with their dose reduction potentials and methods. In this study, a PC-based ORE database program, INSTORE, is developed to evaluate ORE doses in individual jobs, and the ORE data of Kori Units 3 and 4 are assembled to the database. Based on customary job classification, radiation work is classified into 26 main jobs which comprise 61 detailed jobs, and occupational doses are assessed according to each detailed job. As a result, high-dose jobs are identified with dose reduction priority in terms of collective ORE dose. It is recommended that adeqaute dose reduction methods for these jobs should be prepared to improve their working conditions and procedures.

  • The purpose of this paper is to find out the relative priority among the queueing products for next operation. Critical ratio scheduling is a technique for use in production scheduling to establish and maintain relative priority among the jobs. The relative priority is based on a ratio of when the completed job is required and how much time is required to complete it. A numerical example of "D" company is solved. Jobs are classified into 3 categories; the behind scheduling jobs, the on time jobs and the ahead scheduling jobs.

  • The objective of this study was to investigate whether childcare teachers' job satisfaction plays a mediating role between their intention to change jobs and directors' emotional leadership. The participants of this study were 282 childcare teachers in Seoul. The instruments for this study were Director's Emotional Leadership Scale (2 factors with 18 items), Childcare Teacher's Job Satisfaction Scale (K-CTJSS, 6 factors with 40 items), and Childcare Teacher's Intention to Change Jobs Scale (1 factor with 7 items). These instruments were verified by Cronbach's ${\alpha}$ as a reliability and factor analysis as a validity. The data were analysed by Pearson's productive correlation, stepwise multiple regression and path analysis by the SPSS ver. 20.0 and AMOS ver. 20.0. The results were as follows: First, there were significant negative correlations between directors' emotional leadership and childcare teachers' intention to change jobs, and between childcare teachers' job satisfaction and their intention to change jobs, whereas there were significant positive correlations between directors' emotional leadership and childcare teachers' job satisfaction. Second, the directors' emotional leadership was explained by 22% and the childcare teachers' job satisfaction was explained by 9% of their intention to change jobs. Last, the childcare teachers' job satisfaction mediated between the directors' emotional leadership and childcare teachers' intention to change jobs.

  • The purpose of this study was to investigate the influences of organizational culture and childcare teachers' job satisfaction on their intention to change jobs. The participants of this study were 290 childcare teachers from the Busan and Gyeongnam areas. The instruments used in this study were the Organizational Culture Scale (4 factors with 16 items), Childcare Teacher's Job Satisfaction Scale (6 factors with 40 items), and Childcare Teacher's Intention to Change Jobs Scale (1 factor with 7 items). The data were analyzed by descriptive statistics, one-way analysis of variance, Pearson's product moment correlation, and stepwise multiple regression with SPSS ver. 21.0 software. The results were as follows: First, the higher childcare teachers' intention to change jobs, the lower was their monthly income, age, and career level, and the total number of children that they had to serve. Second, there were significant positive correlations between childcare teachers' intention to change jobs and their innovative, collective, and rational organizational culture. Further, there were significant negative correlations between childcare teachers' intention to change jobs and hierarchical organizational culture. and between childcare teachers' intention to change jobs and their job satisfaction. Finally, childcare teachers' intention to change jobs was found to be 46% about job satisfaction and organizational culture and was explained the most by the director's childcare center management. This study primarily suggests that a director's role is important in the lowering of childcare teacher's intention to change jobs.

  • In general, the line balancing problem is defined as of finding an assignment of the given jobs to the workstations under the precedence constraints given to the set of jobs. Usually, the objective is either minimizing the cycle time under the given number of workstations or minimizing the number of workstations under the given cycle time. In this paper, we present a new type of an assembly line balancing problem which occurs in an electronics company manufacturing home appliances. The main difference of the problem compared to the general line balancing problem lies in the structure of the precedence given to the set of jobs. In the problem, the set of jobs is partitioned into two disjoint subjects. One is called the set of fixed jobs and the other, the set of floating jobs. The fixed jobs should be processed in the linear order and some pair of the jobs should not be assigned to the same workstations. Whereas, to each floating job, a set of ranges is given. The range is given in terms of two fixed jobs and it means that the floating job can be processed after the first job is processed and before the second job is processed. There can be more than one range associated to a floating job. We present a procedure to find an approximate solution to the problem. The procedure consists of two major parts. One is to find the assignment of the floating jobs under the given (feasible) assignment of the fixed jobs. The problem can be viewed as a constrained bin packing problem. The other is to find the assignment of the whole jobs under the given linear precedence on the set of the floating jobs. First problem is NP-hard and we devise a heuristic procedure to the problem based on the transportation problem and matching problem. The second problem can be solved in polynomial time by the shortest path method. The algorithm works in iterative manner. One step is composed of two phases. In the first phase, we solve the constrained bin packing problem. In the second phase, the shortest path problem is solved using the phase 1 result. The result of the phase 2 is used as an input to the phase 1 problem at the next step. We test the proposed algorithm on the set of real data found in the washing machine assembly line.

  • A standardized ergonomics kit is suggested to evaluate and reduce musculoskeletal hazards that yield large socioeconomic burdens in the work system. This kit comprises basic and detailed analysis tools with proper tool selection rules. The basic tool includes a checklist for various risk factors to screen potentially hazardous jobs among manual works. Selective detailed analysis tools can then be applied to the screened job lists for more quantitative and precise evaluation. The tool selection rules are devised for using the basic and detailed analysis tools in a mutually supplemental way. To validate the standardized ergonomics kit, it was applied to evaluate jobs related to the musculoskeletal hazards in a paper-making industry. Among 101 manual jobs investigated, 44 potential hazardous jobs were screened during basic investigation phase and finally 16 hazardous jobs were identified by the detailed analysis phase. The result provided fairly promising ideas of ergonomic interventions for the hazardous jobs.

  • Purpose: The purpose of this study was to investigate the image about emergency medical technology (EMT) jobs and to identify factors influencing the image of EMT jobs among students of this department. Methods: A self-reported questionnaire was administered to 532 paramedic students in the cities of D, G, and J between May 28 and June 19, 2013. Data were analyzed by using the SPSS version 21.0 program. Results: The image about EMT jobs was positively related to self-esteem. However, the image about EMT jobs was negatively related to grade and hospital practice experience. In the multiple regression analysis, the adjusted $R^2$ value was .220 (p < .001). Conclusion: The importance of enhancing the self-esteem of paramedic students should be emphasized. Further research on the image about EMT jobs in the hospital practice setting is needed.

  • Purpose. The purpose of the study was to categorize nursing students' subjectivity in their attitude toward their jobs, and thereby understand the differences among these attitude types. Methods. The study used a Q-method to measure nursing students' attitude toward jobs identity types. In-depth and objective interviews and literature review formed Q sample. The P sample consisted of 25 nursing students. Results. The results of the study show that nursing students can be categorized into three types, depending on their attitudes toward their jobs. The firs type, 'interest-oriented' students, strongly disagree to the follow-ing: giving priority to job over marriage, standing unfair treatment in the workplace, the importance of pro-motion opportunity, irresponsibility, and uncertainty. The 'reward-oriented' students, on the other hand, strongly disagree to the following: indifference to career prospects, employment-related relocation of residence, irresponsibility, standing difficulties, and compromises with others. The third type of nursing students is the possession-oriented students, who strongly disapprove of irresponsibility, refusal to compromise with reality, standing unfair job allocation or promotion and career uncertainty. Conclusions. The study on nursing college students' attitude toward their jobs is meaningful in the following aspects: First, the study clarifies nursing college students' attitudes toward their job by categorizing it. Second, the study confirms the changing attitudes of nursing students toward jobs with the change of times and calls for proper educational programs to foster healthy career attitudes. Third, proper decision-making as regards jobs and job allocation for nurses, or their career attitudes, is beneficial to individuals, the medical industry, and society.
