We present an early result of a research for formalization of the characteristics and effectiveness of manufacturing performance measurement systems (PMS). Recently manufacturing PMS has been a focus of broad research efforts due to its practical role playing in managers' decision making process. There have been so many suggestive researches that explain the troubles with old cost accounting-based PMS and describe the desirable properties of PMS in strategic management of manufacturing operations. The lack of empirical investigation in this area, however, has left us unsure about what are the real characteristics that distinguish one PMS from another. In this paper, we propose a conceptual framework that can be used to describe the environment, in which a specific PMS works, the characteristic and the utilization variables of a PMS. Then we report the result of a field survey, where we found three distinctive characteristics of a PMS, contents, vertical integration, and horizontal integration. Further, we discuss the relationships of the variables with the utilization of PMS, manufacturing strategy, manufacturing improvement programs, and business performance.

This technical report provide practical waterwork management system by using CDMA telecommunication method. Local water supply unit and tude-well unit which is placed in the mountainous area could be controlled remotely by MMI monitoring system. Developed method of waterwork managing system is a newly application area of CDMA technology which include web-based control units.

Knowledge Management (KM) is a collaborative and integrated approach adopted at various levels to ensure that an organization's knowledge assets are best utilized to increase organizational performance. While KM has been adopted in a large number of sectors and organizations, colleges and universities, and the higher education sector in general, is yet to take full advantage of the possibilities offered by KM. Also, while past research has sought to highlight the importance of implementing KM in higher education, there is a lack of a single, clear template for KM implementation that universities leaders and administrators can adopt. The contribution of the paper is a practical, actionable, step-by-step plan, as well as a diagrammatic, theoretical framework for initiating KM successfully in colleges and universities.

The Closed Control System, which uses exclusive network and protocol, have been adopted in TM/TC systems. However, the Closed Control System is known that it is not able to support the integration in the water management automation. There are two methods in integration solution in different types of TM/TC System. One solution is hardware system integration that is very expensive and impractical. The other solution is software system integration that uses OLE for Process Control(OPC). In this study, we recommend OPC solution, for KARICO water management, that is the practical and efficient. KARICO is using OPC technology in MMI(Man machine Interface) and water management program. Through this technology, the real-time status of reservoir, pumping station and canal can be achieved without difficulty.

Since late 1990's, the Fish Aquiculture Households belong Fishing Community have been faced very serious pressure of management. The surface factors of this situation have been understood to overproduction and too much imports from China, but basic factor was caused structural problem, that is considered small scale production system. Then, We should enlarge scale of the Fish Aquiculture Households belong Fishing Community to overcoming profitability aggravation. To the Enlargement of Scale, We should consider to change the regime of Fishing Community that means two practical programs. First, it need to enlarge the scale of Fishing Community than now, and Second, it need to incorporate the Fishing Community for exclusive Management of Fish Aquiculture Rights.

I have tried to find a concept among different perspectives on knowledge management. A practical framework of the enhancement of firm's competence through knowledge accumulations was developed as follows: First, All human factors should be armed with information based knowledge and leaded by chief knowledge officer. Second, Learning organization is necessary to develope knowledge creation. Third, Organization has to be controlled by information based control system for the effective linkage of several sort of information. Fourth, Shared culture of knowledge internalized by all members must help organization generate and articulate a new form of knowledge. Finally, Several information technologies and instrumental system may faster creation of knowledge. Especially, in this paper, focused on role of knowledge-based people. It is new view of knowledge-based management studies.

The current study attempts to expand our understanding of the determinants of energy-saving technology (EST) use by focusing on the individual aspects of environmental behaviors. This study integrates the hedonic, normative, and gain goals to explain the causal relationship between users and EST use. By adopting Goal-Framing Theory, this study proposed three individual goal frames in the environmental context: hedonic (perceived pleasurability), normative (social norms), and gain goals (legislative pressure and economic factor). Partial Least Square (PLS) was used to analyze the data from 104 respondents. Eight of the ten hypotheses were strongly supported. We found that social norms, perceived pleasurability, economic factor, and legislative pressure had positive and significant effects on attitude to EST use. Interestingly, we found that media influence did not have a severe effect on perceived pleasurability, and that the economic factor enforces mainly positive attitude to EST. Important theoretical and practical implications of these findings are discussed.

This study investigates empirically the job satisfaction and turnover awareness of the R&D manpower working in company research laboratory. Through the analysis of 106 questionnaires and individual depth interview with R&D manpower who is evaluated as cove researcher in research lab., this study obtains the practical informations on the understandings of their workplace and the extend of turnover awareness etc. The result shows that the many researchers have turnover-minded to improve job stability and develop their career. They think themselves as a cove competent person, but their performances aye not recognised by the organization as they expected level. And the result indicates that many of them haven't find their visions in the workplace.

We propose dynamic file allocation method in distributed database management system with changing access patterns. There are a lot of studies on file allocation problem in D-DBMS, and those studies deal with off-line analysis and optimization. Those works are well for systems with static database access patterns, but are inadequate for systems that have changing access patterns. In these systems, dynamic file allocation along with access pattern is more proper. In advance, Brunstrom et al. studied on this area, but they dealt a extremely simplified model. So, we make more practical models to simulate real system. In these models, many factors that were disregard in the advance study are considered. These models are composed with the non-replication system and the replication system. In addition to, we deal with CPU workload balancing in such system in order to improve performance of systems. Our methodology is very simple and realistic, therefore we think that it will give a lot of improvement in D-DBMS with changing access pattern.

Water management for Polymer Electrolyte Fuel Cell (PEFC) has been receiving large attention as an important issue in practical applications. Proper water management is vital to achieve high performance and durability of PEFC. In this study, an X-ray imaging technique was employed to visualize the water distribution in a PEFC quantitatively. X-ray images of the PEFC components with and without water are distinguished clearly. From the visualized X-ray images, we could confirm the water distribution in the region between separator and gas diffusion layer (GDL). In addition, the contact angle of water in the micro-channels was also clearly visualized..
