The Systems Engineering Management Plan (SEMP) is the primary, top level technical management document for the integration of all engineering activities at the project plan phase. This document defined the activities to plan, control, and perform overall engineering integration. To develop the SEMP for Railway Safety System, several standards are reviewed and analyzed. And then a common requirement for SEMP preparation is derived from the results of analysis. Also, the SEMP example available practically applies to Railway Safety System. In particular, The SEMP focused on controling technical program management has been organized so far, but in this study the detailed contents of SEMP put stress on project management is derived. And it is related to each other between project management and technical engineering management. At the end, to continuously manage the items and contents of the SEMP, a database management and an automatic document generation system is presented using Computer-Aided Systems Engineering (CASE) tool.

The medical records of diagnostic and testing information include sensitive personal information that reveals some of the most intimate aspects of an individual's life. The hospital information system (HIS) operates in a state of high risk which may lead to the possible loss to the IS resources caused by various threats. This research addresses twofold : (1) to perform asset identification ad valuation and (2) to recommend countermeasures for secure HIS network using case studies This paper applied a risk management tool CRAMM (Central Computer and Tele-communications Agency's Risk Analysis and Management Method) to assess asset values and suggest countermeasures for the security of computerized medical information of two large hospitals in Korea. CRAMM countermeasures are recommended at the reference sites from the network security requirements of system utilized for the diagnosis and treatment of patients. The results of the study will enhance the awareness of IS risk management by IS managers.

The purpose of this study was to empirically verify the influence of socio-demograghic and psychological variables and the way of housework management on the satisfaction of housework management and to provide the information of enhancing the quality of life. In conclusion, the employed wives had tried to select and perform the way of household work management reducing the overload by multiple role performance. And then, it was influenced by housewives' individual resources and family resources. In order to accomplish the higher level of satisfaction of household work management, they must be selected and performed the effective ways of household work management that they are able to use.

This paper analyzes mobile agent performance in network management compared to the client-server model used in the Simple Network Management Protocol (SNMP). Prototypes of an application that gathers MIB-II (Management Information Base-II) variables have been created and tested on a LAN. After acquiring implementation parameters related to network management and to the mobile agent infrastructure, simulation results have been obtained on large topologies similar in shape to the Internet. Response time results show that mobile agents perform better than SNMP when the number of managed elements ranges between two specific limits, an inferior bound and a superior one, determined by the number of messages that pass through a backbone and by the mobile agent size which grows along with MIB-II variables collected on network elements. The results also show that a significant improvement is achieved when the mobile agent returns or sends data to the management station after visiting a fixed number of nodes.

This study was performed to review applying the case management to the occupational health nursing as a cost-effective way for injured workers. The case management for injured workers is a comprehensive management system, which is composed of planning and implementing in cooperation with employee, employee' family, medical service provider team, employer and case manager, to provide high quality health services to employee and their family. The case management process for injured workers is similar to the nursing process. It thus appears that the occupational health nurse is best personnel to perform the role of case manager for injured workers in workplace. As a case manager in workplace. the occupational health nurse would be expected to get both knowledge and experiences, to get trusted from the employee and employer, and to expand professional domain in changing health care environment.

In recent years, there have been many attempts to connect the latest RFID (Radio Frequency Identification) technology with EIS (Enterprise Information System) and utilize them. However, in most cases the focus is only on the simultaneous multiple reading capability of the RFID technology neglecting the management of massive data created from the reader. As a result, it is difficult to obtain time-related information such as flow prediction and analysis in process control. In this paper, we suggest a new method called 'procedure tree', an enhanced and complementary version of PathTree which is one of RFID data mining techniques, to manage massive RFID data sets effectively and to perform a real-time process control efficiently. We will evaluate efficiency of the proposed system after applying real-time process management system connected with the RFID-based EIS. Through the suggested method, we are able to perform such tasks as prediction or tracking of process flow for real-time process control and inventory management efficiently which the existing RFID-based production system could not have done.

In this paper, we propose a new customer profile model based on customer behavior in Internet shopping mall. The proposed technique defines customer profile model based on customer behavior information such as click data, buy data, and interest categories. We also implement CBCPM(Customer Behavior-based Customer Profile Model) and perform extensive experiments. The experimental results show that CBCPM has higher precision, recall, and F1 than the existing customer profile model.

In this study, we attempt to improve analytical methods in auditing by applying Artificial Intelligence(AI) methods including Artificial Neural Networks(ANN) and Case-Based Reasoning(CBR), and to perform pattern recognition of the investigation signals generated by analytical procedures. Five years of audited financial data from a large-sized firm were used to calculate four commonly applied financial ratios. This exploratory study shows that the use of AI methods to analyze patterns of related fluctuations across numerous financial ratios provides improved performance in recognizing material misstatements within the financial accounts.

The purpose of this paper is to analyze the actual condition, the result and the problem of the military defense CALS system and seek the way of the effective use of the military defense CALS. We perform an analytic hierarchy process to find the factors that have an influence on the effective use of CALS and evaluate the level of importance of these factors. Also we estimate the actual condition and the result by the Likert 7 scale.

This paper suggests a procedure of decomposing a multi-stage dynamic location problem into stages with respect stage. The problem can be formulated as a mixed integer programming problem, which is difficult to be solved directly. We perform a series of transformations in order to divide the problem into stages. In the process, the assumption of PSO (production-system-only) plays a critical role. The resulting subproblem becomes a typical single-stage dynamic location problem, whose efficient algorithms have been developed efficiently. An extension of this study is to find a method to integrate the solutions of subproblems for a final solution of the problem.
