This paper proposes a methodology to measure the risk level in real-time for Business Activity Monitoring (BAM). A decision-tree methodology was employed to analyze the effect of process attributes on the result of the process execution. In the course of process execution, the level of risk is monitored in real-time, and an early warning can be issued depending on the change of the risk level. An algorithm for estimating the risk of ongoing processes in real-time was formulated. Comparison experiments were conducted to demonstrate the effectiveness of our method. The proposed method detects the risks of business processes more precisely and even earlier than existing approaches.

Refinery plant producing petroleum products from crude oil has significantly contributed to the creation of the national interests as a leading engineering industries. However, domestic Engineering Procurement Construction (EPC) companies are facing heavy competition for orders. Domestic EPC companies as EPC contractors are faced with some problems such as undertaking responsibility for FEED packages produced by other FEED companies. But domestic EPC contractors are unfamiliar to development and validation of FEED packages. It causes poor profitability and lower competitiveness of domestic companies. It is necessary for domestic companies to have capability to perform FEED activities in order to overcome these limitations instead of focusing on EPC phase after FEED phase. The systematic procedure is needed to perform the FEED activities, however, there are present difficulties on it due to the lack of experience in FEED packages development which require various engineering knowledge of chemical process, mechanics, electrics, instrumentation, civil engineering. This study has applied systems engineering method which is multi-disciplinary approach to derive and verify the solution to meet the customer's needs when the complex system is developed to task execution process development of FEED activities for refinery plant. The problems that may occur in the future were identified in advance by taking into account the various stakeholders and system context through the application of systems engineering. It helps to develop the task execution process systematically. The developed task execution process of FEED activities is planned to make effectiveness verified by engineering professionals experienced in FEED and continually enhance this process by field application.

This paper proposes a BPM(Business Process Management) system framework for the NPD(New Product Development) of automotive suppliers. Recently many enterprises change their organization from function-oriented to process-oriented through BPR (Business Process Reengineering). Especially, based on quality systems like QS9000, it is required to documented business processes and continuously improve these processes for customer satisfaction. NPD, the most significant function for industrial competition, is reinforced by the best practices business process to satisfy the requirements of quality systems. The main objective of the paper is the development of the information system that supports the best practices process management. For this, first, we define the requirements of BPM system for NPD based on the viewpoint analysis, and then propose a DES (Design Execution System) framework based on dynamic workflow engine. The DES is addressed in the characteristics of a NPD business process, integrated project management, and process execution. A prototype DES system has been developed in the web environment. Its validity is demonstrated by applying it to an automotive supplier.

Purpose: This study examined the influencing factors from the Transtheoretical Model on the stage of change in the self-management behaviors, i.e. regular physical activity and diet, among community-residing adults with hypertension in a rural area. Methods: With a cross-sectional descriptive design, 134 adults who had registered and received a prescription for hypertension medication from a public health center in W city were recruited using convenient sampling. The instrument was an interviewer-administered questionnaire on the stage of change, process of change, self-efficacy, and decisional balance of physical activity and diet. The data were analyzed using descriptive statistics, 2-sample t-test, ${\chi}^2$ test, and logistic regression. Results: The results revealed significant differences in the process of change, self-efficacy, and decisional balance of physical activity and diet between those who were in the pre-execution stage (precontemplation, contemplation, preparation) and those who were in the execution stage (action and maintenance). Logistic regression showed that consciousness raising and self-efficacy were significant predictors of the execution stage in physical activity, and self-reevaluation, social liberation and self-efficacy were significant predictors in the diet. Conclusion: The relevant processes of change, differentiated according to the stage of change, along with self-efficacy, should be addressed to enhance the execution of self-management behaviors among hypertensive adults residing in the community.

For decades, the productivity issue has been a primary concern for the all stake-holders who participate in domestic construction industry. Especially, between a whole life cycle of building, the construction phase's productivity problem makes or break the entire project. In this respect, the general construction company, who accept the order and construct the building(so called General Contractor), should consider various strategies, such as schedule management, cost management, quality management, inner-crew management, etc., for the productivity improvement., and almost of these management methods have been studied for a long time. But, the researches and studies about the specialty contractor, who construct the building directly in construction site were not sufficiently complete yet. This research begins as an idea which tries to apply the BIM(Building Information Modeling) into the tasks of Specialty contractors for their productivity improvement. And for the effective application of construction BIM to specialty contractors, establish of the BIM project execution plan for them, not the fragmentary adoption of BIM. Therefore, in this paper, we develop the BIM project execution plan for the reinforced concrete companies who conduct the framework construction which located on CP(Critical Path) Especially, we model the "Construction BIM Use List for the RC Work", "BIM Application Master Process" and "BIM Application Detailed Process", and general contractor who use these BIM uses list and process models can manage various specialty contractors about schedule, cost, earned value, quality, safety and environment management systematically.

At NOW (Networks Of Workstations), the load sharing is very important role for improving the performance. The known load sharing strategy is fixed-granularity, variable-granularity and adaptive-granularity. The variable-granularity algorithm is sensitive to the various parameters. But Send algorithm, which implements the fixed-granularity strategy, is robust to task granularity. And the performance difference between Send and variable-granularity algorithm is not substantial. But, in Send algorithm, the computing time and the communication time are not overlapped. Therefore, long latency time at the network has influence on the execution time of the parallel program. In this paper, we propose the preSend algorithm. In the preSend algorithm, the master node can send the data to the slave nodes in advance without the waiting for partial results from the slaves. As the master node sent the next data to the slaves in advance, the slave nodes can process the data without the idle time. As stated above, the preSend algorithm can overlap the computing time and the communication time. Therefore we reduce the influence of the long latency time at the network and the execution time of the parallel program on the NOW. To compare the execution time of two algorithms, we use the $320{\times}320$ matrix multiplication. The comparison results of execution times show that the preSend algorithm has the shorter execution time than the Send algorithm.

Purpose: In recent years, since 2000 many hospitals have established a master plan. However, there are some hospitals proceeding in different way from the master plan while the process of execution plan. This is because the study of master plan has been incomplete yet and there is no feedback on the master plan. Therefore, the purpose of this study is to find the reasons why differences are occurred. Methods: Comparison analysis of five hospitals which have established master plans and constructed with execution plans and Questionnaire to an architect of execution plan have been conducted. Results: This study has found three points. The first one is the change in scope of business and the change of administrator. The second one is that administrator and staff of hospital have more demands for improvement in functional area rather than public area, like lobby. The last one is to check a possibility of the solution by architectural analysis. Implications: It is necessary to determine the cause of changes from master plan and execution plan, in order to reduce the change in advance.
