A great number of job seekers are referring to job search sites in order to obtain useful information about employment and the number of job search sites is increasing owing to the various needs of the job seekers. The main role of such sites, however, is merely an information provider, and this causes the mismatch between the potential employers and the employees. Therefore, this paper suggests a customized job information system between college students and affiliated companies so as to mitigate the chance of mismatches.

It is not easy for business workers to find proper information for his job, because of the following problems:(1) information exist in various information system both internal and external with diverse formats(2) he cannot estimate relevance of all the information and (3) he cannot select proper information among large volume of information. The requirements for the systems are the following things:(1) search of relevant information from various internal and external information systems(2) proving an integrated view of information for workers, and (3) information processing and decision-making are seamlessly integrated fro business workers. We proposed an agent system to fulfill the requirements. We focus on the purchasing job, and developed a prototype system. PIPA(Purchasing Information Process Agent). The PIPA performs not only information processing jobs(information search gathering, display, business form -making)but also decision-making support job (evaluation of supplier candidates, and apply of sourcing policy) for sourcing manager. The framework of the PIPA can be appled to other information processing and desision-making jobs.

This study is about implementing an job matching web service system based on the Job seeker's company assessment model proposed by the researchers. Basically, the Job seekers' company assessment model is based on the concept that each job seeker can evaluate the recruitment company candidates using job seekers's own major consideration factors. Using the implemented information system, each job seeker's main considerations in job searching process are evaluated and stored and compared to those of other job seekers' or groups' characterized by sex, job experience residential area and etc. by finding out and listing up the companies in the order of the preference of job seeker own or belonging groups, job seekers can be helped to find suitable companies which fit well to themselves.

The Sido.Saeol system, a local government information system cost too much for having been designed and developed during last four years but the effectiveness of this system is still open to doubt. Also maintenance cost is still too high and become increasing year by year. To find out the reasons and to suggest how to solve these problems, a service quality of an Sido Saeol system and the public servant's job satisfaction were investigated based on the Delone and McLean's updated IS success Model(2003). To investigate of the effectiveness of the Sido Saeol system, 8 variables are analyzed to test 3 main hypothesis. After all the analysis, we found that Sido.Saeol systems have many aspects to be improved for system use and job satisfaction and have to be revise in the aspects of system qualities.

Mobile grid is a combination of grid computing and mobile computing to build grid systems in a wireless mobile environment. The development of network technology is assisting in realizing mobile grid. Mobile grid based on established grid infrastructures needs effective resource management and reliable job scheduling because mobile grid utilizes not only static grid resources but also dynamic grid resources with mobility. However, mobile devices are considered as unavailable resources in traditional grids. Mobile resources should be integrated into existing grid sites. Therefore, this paper presents a mobile grid middleware interconnecting existing grid infrastructures with mobile resources and a mobile service agent installed on the mobile resources. This paper also proposes a mobile resource reliability-based job scheduling model in order to overcome the unreliability of wireless mobile devices and guarantee stable and reliable job processing. In the proposed job scheduling model, the mobile service agent calculates the mobile resource reliability of each resource by using diverse reliability metrics and predicts it. The mobile grid middleware allocated jobs to mobile resources by predicted mobile resource reliability. We implemented a simulation model that simplifies various functions of the proposed job scheduling model by using the DEVS (Discrete Event System Specification) which is the formalism for modeling and analyzing a general system. We also conducted diverse experiments for performance evaluation. Experimental results demonstrate that the proposed model can assist in improving the performance of mobile grid in comparison with existing job scheduling models.

This study explored the performance factors of casino information systems for foreigners, empirically examined the causal relation between these factors and the business performances through organizational trust and job satisfaction and suggested a direction to enhance the casino information systems. The result of this study showed that, firstly, information quality impacted positively on security reliability and job satisfaction. Secondly, system quality impacted positively on security reliability and job satisfaction. Thirdly, service quality impacted positively on security reliability and job satisfaction. Fourthly, security reliability impacted positively on job satisfaction through security reliability. Lastly, security reliability and job satisfaction impacted positively on business performance. This research must be continued by expanding upon the variables of this research study, and there is a need for follow up research on methods that can analyze the management performance of casino information systems from a diverse set of approaches and also research that conducts an analysis on systems that are implemented to prevent tax evasion.

This study is a measurement of effectiveness to a job process for the hospital information system (HIS) used in the hospital industry. Using the effectiveness scale that I developed in the questionnaire of the ISO9241-11 quality model, I measured the importance level of HIS and its significance on a job practices in the large general hospitals within the country. The questionnaire showed that the importance level of domestic HISs was highest in the system used by staffs(mean=3) and to reduce a job process and increase the efficiency of work.
