Purpose: This study focuses on doctors' role expectation and patients satisfaction with the referral centers to get necessary basic Method: There were 495 subjects in this study. 245 of them were doctors working in the 397 clinics and hospitals which have made contracts with the referral center in Y General Hospital located in J city, and 250 were patients who had been treated in it. The data were collected from Sep. 25 to Oct. 21, in 2006. Data analysis was processed with SPSS/WIN 14.0 electronically. Results: Concluding cooperative treaties with other clinics and hospitals, doctors expect the following effects: First, the improvement of the treatment quality of patients. The patients satisfaction ranking order for using referral centers is as follows: kindness of the staff, treatment reservation, doctor's satisfying explanation. providing one-stop service, reduction of waiting time for treatment, evasion of repetitive tests. Conclusion: Referral centers should provide various services totally and actively which reflect the role expectation and satisfaction of doctors and patients altogether.

Contingency response in a FMS system requires that the system be able to identify and evaluate a number of alternatives. This paper is outlined that DSS completes with a problem processor in corporating Timed Petri Nets model, and a data base system. DSS enables the FMS user to get the maximum benefit from a FMS. The structure of this DSS parallels the organizational activities involved in running the FMS. In designing a shop floor controller for FMS, interactions between the different real time, discrete event functions must be established. The specification of the machine tool and material handling system functions working as a concurrent and cooperative system is given in terms of Timed Petri Nets. In addition, the basic concepts and uses of Petri Nets are surveyed. The system to be studied is first modelled by a Timed Petri Nets and then procedure for evaluating the FMS system performance are presented. Numerical examples are studied to illustrate a session of the FMS used-DSS interaction.

Presented in this paper is a control model for developing virtual factory simulator, which is being operated under the distributed environment. The control model consists of production activity plan and information flows. To incorporate elements of the characteristics of the distributed control system, we suggested a collaboration model. This model is working under the client/server architecture, and also designed for cooperative-distributed shop control(CDSC) system in order to exploit several advantages of client/server architecture. Collaboration among each agent(or client) is done through negotiation and task sharing. Based on a contract net model, the CDSC system has three kinds of agents-order agent, resource agent, and communication forwarding agent. Each agent performs shop scheduling and control through negotiation on contract net. No node in CDSC system can have authority over other node. A bidding scheme is employed far negotiation between order agent and resource agents. The CDSC system can support re-negotiation among resource agents and an algorithm for re-negotiation is also developed. Experimental results are shown to advocate the effectiveness of the CDSC system for CIM environments.

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.

R&D association is a very important institution to promote inter-firm technological cooperation, In Korea, they have begun to be established in 1982, and at now 56 R&D associations are working. The purpose of this study is In analyze the problems of the R&D associations, and to suggest a new direction of their future development Their problems were analyzed from the perspective of cooperative R&D mechanisms, especially with a new concept of R&D community : search community, planning community, community of research itself. This study emphases the importance of the R&D association's role as a planning community, and the institutional linkage between R&D association and National R&D program through the introduction of design-in planning system.

To promote academic researches on earth environment utilizing satellite data, research infrastructure such as satellite data reception processing, distribution and archival systems should be fully provided. The means to enhance the infrastructure were discussed by a working group and“Satellite Data Center via Network”has been proposed. This concept has three principles; (1) To realize necessary functions by organizing experts distributed all over Japan and connecting them by network, (2) To realize“Satellite Data Center via Network”for GMS and NOAA Satellites, which are widely used for research, and (3) Satellite data set oriented to specific research area should be generated by researchers having definite research purposes of sensor algorithms and hugh volume data processing. Utilization of the Science Information Network (SINET) has been discussed to realize this concept, and to accelerate this project an experiment“Network Utilization for Wide Area Use of Satellite Image Data”under“Cooperative Experiment on Multimedia Communication”has been introduced. And the roles of the Institute of Industrial Science, University of Tokyo to contribute this project has been described.

Industrial Psychology is to study and analyze human behavior or working at operation, both to look into the rules in that and to make analysis of rules made from theological basis adapted to reality, wi th methods and knowledges that Psychology gives, by methods that are observation, experiment , investigation and so on, to contribute to improving the production efficiency and promoting the Laborer's welfare, In this paper, the side of Psychology in labor accidents will be studied as follows. 1.The Presentation of Problems 1.1. Concept prescription of Industrial Psychology 1.2. Relation between Industrial psychology and accidents 2.The Theorical approach of Industrial Psychology for accident study 2.1 Industrial Psychology in approach of accident study 2.2.

The indicated power of Stirling engine was affected by the heat exchange effectiveness of the regenerator. The temperature difference of working fluid between the expansion and the compression space of Stilting engine depends on the heat exchange effectiveness of the regenerator. The influence of the temperature ratio of expansion space to compression space of Stirling engine on the indicated power was analyzed by using Schmidt analysis in this study. In the Stirring engine, as the temperature ratio increased, the indicated power generally decreased. Therefor, it is necessary to develope the regenerator of high effectiveness. The actual indicated power was shown 64.9 percent of the predicted indicated power in maximum and 47.2 percent of that in minimum due to increased dead volume of engine, the loss of flow friction and heat transfer in the regenerator.

과거의 전통적인 기업들은 서로 독립적으로 자유 경쟁을 수행하면서 그들의 목적을 추구하였으며 이때의 전략은 경쟁전략이 우선 이였다. 그러나 최근에 와서 세계 기업의 전략 동향을 분석하여 보면 경쟁전략 보다는 협력 전략이 기업의 목표를 달성하는데 있어서 더 효과적이고 효율적으로 생각되고 있다. 본 논문에서는 이를 검토하고 또한 아시아의 위기에 대한 바람직한 대처방안의 모형을 제시코자 한다.

This paper present a novel 6-axis robotic base platform with force/moment sensing. The robotic base platform is made up of six loadcells connecting the moving plate to the fixed plate by spherical joints at the both ends of loadcells. The statics relation is derived, the robotic base platform prototype and the loadcell measurement system are developed. The force/moment calibrations in joint and Cartesian spaces are performed. The algorithm to detect external force applied at a working robot is derived, and using a 6-DOF robot mounted on the robotic base platform, force/moment measurement experiments have been performed.
