The Grid system is an emerging computing infrastructure that will substitute for existing distributed systems. However end users have a difficulty in using the Grid because of its complicated usage, which is an inherent characteristic from the heterogeneous mechanism of the Grid. In this paper, we present the JCML(Job Control Markup Language) and its GUI-based editor, which not only provide users with ease of use, improved working environment, but assist users to execute their jobs efficiently The JCML is a job control language that improves the RSL of Globus, which defines global services in Grid. The JCML is designed to support flexibility among various Grid services using standard XML. And it makes use of a graph representation method, GXL(Graph eXchange Language), to specify detailed job properties and dependencies among jobs using nodes and edges. The JCML editor provides users with GUI-based interface. With the JCML editor, a complicated job order can be easily completed using very simple manipulations with a mouse, such as a drag-and-drop.

The study aims at understanding records professions' job areas and conducting the Importance Performance Analysis. Under the perception which it is necessary to analyze records professions' job for securing their roles and identity, this study conducts a job analysis and categorizes records professions' job into 4 duties, 19 jobs and 78 job elements. The 4 duties includes records management, records office operation, records management infrastructure, and records information services. Furthermore, it researches jobs' importance and performance using the IPA. Accordign to the analysis, the jobs which rank at top of the importance and performance list are jobs concerning appraisal and disposal. The jobs which ranks at bottom are jobs related to services. In general the current 'one man records office system' is not appropriate to carry out all the records management business. In this context, it is necessary to lighten records profeesions' workload through the job adjustment in government institutions.

The purpose of this study was to determine the associations among emotional burnout, resilience, job embeddedness, and organizational commitment, provide basic data for an effective dental care delivery system and manpower management, and promote organizational commitment in clinical dental hygienists. For data collection, convenience sampling was performed among dental hygienists working in Daejeon and Chungcheong and Jeolla Provinces from November 11 to December 30, 2019, and a self-administered questionnaire was used. Organizational commitment was positively correlated with resilience and job embeddedness and was negatively correlated with emotional burnout; emotional burnout was negatively correlated with resilience and job embeddedness; and resilience was positively correlated with job embeddedness. The factor most significantly affecting organizational commitment was emotional burnout, followed by resilience and job embeddedness. It is therefore necessary to give another consideration to a customized intervention strategy, which involves emotional burnout, resilience, and job embeddedness, in exploring a program that helps clinical dental hygienists maintain and manage organizational commitment efficiently.

In this paper, we research on job migration in a grid computing environment with cactus and MPICH-C2 based on Globus. Our concepts are to perform job migration by finding the site with plenty of computational resources that would decrease execution time in a grid computing environment. The Migration Manager recovers the job from the checkpointing files and restarts the job on the migrated site. To select a migrating site, the proposed method considers system's performance index, cpu's load, network traffic to send migration job tiles and the execution time predicted on a migration site. Then it selects a site with maximal performance gains. By selecting a site with minimum migration time and minimum execution time. this approach implements a more efficient grid computing environment. The proposed method Is proved by effectively decreasing total execution time at the $K\ast{Grid}$.

A fuzzy dispatching algorithm with adaptable control scheme is proposed for more flexible and adaptable operation of AGV system. The basic idea of the algorithm is prioritization of all move requests based on the fuzzy urgency. The fuzzy urgency is measured by the fuzzy multi-criteria decision-making method, utilizing the relevant information such as incoming and outgoing buffer status, elapsed time of move request, and AGV traveling distance. At every dispatching decision point, the algorithm prioritizes all move requests based on the fuzzy urgency. The performance of the proposed algorithm is compared with several dispatching algorithms in terms of system throughput in a hypothetical job shop environment. Simulation experiments are carried out varying the level of criticality ratio of AGVs , the numbers of AGVs, and the buffer capacities. The rule presented in this study appears to be more effective for dispatching AGVs than the other rules.

It has been widely spread that the acquisition and retention of the core personnel is very important for improving firms' competitiveness. Many companies have made a lot of efforts to keep these core personnel, job embeddedness and work satisfaction are important factors which make effects on workers turnover. Prior research applying for many different industries do not show the consistent research results. There is no empirical research applying for construction IT industry which information technology has been playing more important role because of u-city etc. Therefore, in this research job embeddedness and work satisfaction are to be measured and the relationship with turnover intentions are to be investigated focusing on small and medium construction IT workers. The sub-constructs of job embeddedness are fit, links and sacrifice, and the sub-constructs of work satisfaction are career satisfaction and job satisfaction. It is empirically tested how these factors can have effects on the turnover intentions. Field surveys targeted to construction IT workers were done and finally 177 survey questionnaires were used to analyze. Research results show that if the sacrifice, career satisfaction and job satisfaction of small and medium construction IT workers are higher, turnover intentions will be lower. On the other hand, 2 hypotheses are rejected that if the fit and links of these workers are higher, turnover intentions will be lower. These research results clarified the factors affecting the turnover intentions of small and medium construction IT workers and can be utilized how turnover intentions can be decreased practically.

The fourth industrial revolution is expected to bring about great changes in information technology sector and create a variety of jobs. However, the psychological anxiety of IT staff is increasing due to stress and uncertainty created by the new technologies. Accordingly, researchers examined how professional identity moderate the effect of job stress of system maintenance staff on emotion exhaustion. For empirical studies, data was collected from 160 employees responsible for managing and supporting IS, and the hypothesis was verified using SPSS 21. The analysis results showed that role conflicts, role ambiguity, and qualitative work overload, which are components of job stress, have affected the emotion exhaustion. Professional identity had a moderating effect the relationship between qualitative work overload and emotion exhaustion. On the other hand, professional identity did not moderate the relationship between role conflict and emotion exhaustion, role ambiguity and emotion exhaustion. As professional identity lessen the psychological burden and emotion exhaustion of introducing new technologies, organizations need to provide support to enhance professional identity for system maintenance staff.

This study investigated research data-related services offered by North American university libraries, focusing on service names, hierarchical relationships, job titles of service managers, and job descriptions. The study analyzed the homepages of 50 university libraries and found a clear hierarchical relationship between research data-related service names, indicating a clear structure for these services. The title of 'librarian' was most commonly used for the position in charge of research data-related services, and the job content of this position was found to be quite wide. Other job titles such as 'specialist' and 'analyst' were also used for experts in various research data-related fields. The existence of these job titles was seen as a way for university libraries to strengthen the expertise of their research data-related services. Based on the findings, the authors propose a service composition system for research data-related services in domestic university libraries. This system includes 'research data service' as the highest-level service name, with 'research data management service', 'GIS service', and 'data visualization service' as sub-service names. The authors also suggest that research data-related services should be provided through collaboration between existing university librarians in the early stages of service provision, and that new recruitment of research data-related professionals could be considered gradually.
