A project planning is one of the most important processes that determines success and failure of the project. A pre-project planning is also essential job for information system implementations at the early stage of project planning, especially for management information system like ERP. However, pre-project planning is very difficult, because lots of factors and their relationships should be considered. Pre-project planning of ERP implementation has been done by project manager's own knowledge and experiences. In this article, we propose a system that help project manager to make a pre-project plan of ERP project with case-based reasoning(CBR) framework. The proposed CBR system saves previous cases of ERP pre-project planning in the case base. Then, the system finds the most similar case with the current pre-project planning problem. Project manager can make a pre-project plan by adjusting the most similar case. From the interview with project managers, we collect some field cases of ERP implementation. We organized these cases by using XML(Extensible Markup Language), which is good for representing hierarchical information. XML gives us some flexibilities to correct and maintain cases. We make a prototype system, PPSS(Project Planning Support System) that help project manager to make a pre-project plan of ERP implementations. The object of the system is to support project manager to make a pre-project plan of ERP. We hope the result of the study can be applied to other information systems. Our research would be extended to cover other stages of project planning.

This paper describes an electronic performance support system called HELPS(Handler Electronic Learning Performence Support) for semiconductor testing e equipment. The purpose of this system is to improve productivity of operators by providing just-in-time, on-the-job, mutimedia-based system information for operational support, training, and knowledge-based trouble shooting and repair. HELPS is composed of a operation module and a trouble shooting module. The operation module uses multimedia and hypermedia to provide the detailed and easily accessible information about equipment to users. Multimedia incorporate multiple. media forms including still and video images. animations 'texts' graphics. and audio. Hypermedia a are provided through a hierarchical information structure which offers not only specific information which is needed to perform a task to experienced operators. but detailed system guidance and information to novice operators. The trouble shooting module is composed of an integrated mutimedia-supported expert system which assists operators in trouble shooting and equipment repair. After diagnosis through the use of the expert system. multimedia advice is presented to the user in either still images with text or motion sequences with sound HELPS is evaluated in term of training time and trouble shooting and repair time. It improved productivity by saving more than 30% of the total time used without the system. This s system has the potential to improve productivity when it is used with ICAIOntellignet Computer Aided Instruction) and virtual reality.

The purpose of this study was (1)to undertake a survey to identify the profile of inactive nurses, who account for 42.2% of the 130,000 RN(Registered Nurses) in Korea, (2)to identify factors related to the inactivation of these nurses, (3)to identify reasons behind the high turnover rate of nurses, and (4)to delineate measures for inactive nurses to participate in professional nursing activities so as to upgrade the quality of the health care delivery system in Korea. For these purposes, this study surveyed existing literature on the turnover of nurses and, used the nominal group technique of action research, to collect ideas from hospital/nurse administrators, inactive nurses, nurses on the job, graduate students in nursing, part-time nurses, patients, and their families to formulate strategies to mobilize inactive nurses. The findings are as follows : Frist, institutional supports should be provided to mobilize inactive nurses. To be more specific : (1) A data-base needs be created at the Korean Nurses Association to link inactive nurses with jobs available. (2) Retraining programs need be established to equip inactive nurses for new jobs. (3) Comprehensive information related to employment needs should be made available. Second, a conducive environment needs to be created to draw in inactive nurses to the job market. To be more specific : (1) A system of part-time work needs to be introduced in hospitals. (2) Nurse-specialists need to be promoted. (3) Potential jobs need to be created. (4) Working environment and terms and conditions for nurses need to be improved. (5) Competent nurses need to be secured in the health care delivery system. To achieve the goals presented above, this paper presented 55 specific strategies that may help mitigate the turnover rate of nurses and, in turn, help make the Korean Nurses Association effective in implementing its policies.

A bucket-brigade is a way of transporting items where items are passed from one person to the next. The operation of the bucket brigade imitates the cooperative behavior of ants when brood, food or other resources are moved. Koo (2009) presented a bucket brigade-based assembly cell where each worker follows a simple rule: perform assembly operations on a product until the next worker downstream takes it over; then go back to the previous worker upstream to take over a new assembly job. In this way, the flow line is self-balanced without any predetermined job assignment. However, there are some productivity losses related to hand-off and blocking. This paper examines the hand-off and blocking losses and presents a new bucket brigade-based assembly cell where working areas for each assembler is restricted with the help of buffer interfaces. Simulation experiments are used to validate the performance of the new assembly system.

The purpose of this study was to analyze the effect that the social support for social welfare workers who are the key personnel providing the service to children directly at local child care center would have on job satisfaction. For this study, the social welfare workers of local child care center in Jeollanam-do were surveyed. A total of 240 questionnaires which had been collected were used for analysis. This study analyzed the effect of social support on job satisfaction by defining the demographic characteristics of social welfare workers as the control variables. The results of the analysis showed that the social support had the greatest influence on job satisfaction. Such results suggest that the stronger social support for social welfare workers would increase the job satisfaction of social welfare workers. Based on the results of the analysis, the following recommendations are presented which can help increase social support for social welfare workers: First, it is necessary to standardize the works of social welfare workers at local child care center and provide them with specialized training and education. Second, additional points should be granted to excellent local child care centers. Third, a cooperation system needs to be established which links the networks of colleagues and local societies.
