Human works shift its roll from physical condition to the system supervisory control task In this paper safety-presentation configuration is discussed instead of well-known fault-warning configuration. Of paticular interest was the personal factor which include the cognitive process. Through a performance between each person information processing(d') and decision process($\beta$) was pointed out to explain the sensitivity of personal cognitive process. Impact of uncertainty effect the supervisor having doubt situations. These facts are released by the use of flat fuzzy number of $\beta$ and its learning rate R.

The new-type measuring modules for unmanned remote supervisory system using mobile communication network have been designed in this study. Measuring modules consist of temperature measuring module, humidity measuring module and human body sensing module. And we will design a main part to collect and process informations of each modules, evaluate reliability of combined total system.

A total of 725 questionnaires, collected from secondary teachers appointed within the recent three years in the Metro-Busan, were analyzed. According to the results, the novice teachers perceived that supervisory practice in school was helpful for them in the four areas; instructional method, guidance, class management and administrative work, except for human relations, and they felt the need for instructional supervision but the major hindrance to the practice was time constraint.

As many industrial systems become more complex, it becomes extremely difficult to diagnose the cause of failures. This paper presents a failure diagnosis approach based on discrete event system theory. In particular, the approach is a hybrid of event-based and state-based ones leading to a simpler failure diagnoser with supervisory control capability. The design procedure is presented along with a pump-valve system as an example.

This paper discusses the problem of designing an observation function as coarsest as possible in supervisory control of discrete event dynamic systems. Some algebraic properties of two sets consisting of observation functions for which the given desirable behavior is realizable are investigated:these sets with a partial ordering turn out not to possess largest elements. Two natural methods of obtaining an observation function, which is frequently coarser than the identity mapping, are also presented. An example illustrates the use of these methods.

Electric power systems are becoming advanced by using new technology year by year However, in electric power system environments. electromagnetic interference occurs in measurement, supervisory and control systems, especially in sensors. Optical sensor technologies are useful for solving the problem, since they are not affected by electromagnetic interference because they are composed of insulting materials. In this paper, some applications of optical sensor technology to electric power systems are introduced.

There is considerable interest in corporate governance in Korea. One important reason for the increasing interest in it is that the current system of Korean Corporations is the main cause of weakening competitiveness due to problems such as economic concentration, the concentration of shareholding etc. This Study intends to investigate the problems within the current corporate gorvernance system of Korean Corporations, focusing on supervisory system, and to suggest a improvement for it.

This paper presents a method to construct a supervisory monitoring system for railway signaling devices which can provide the real-time operation information of signalling devices to several maintenance depots. Spying technique has been applied to acquire the real-time data transmitted among railway signaling devices without interfering the railway signalling system function.

The purpose of this study explored the effects of supervisory relationship, conceptualized as working alliance, on social workers' working satisfaction and burnout. The consented participants were 68 supervisors and 80 supervisees working at Social Service Centers located in Seoul and Kyung-ki Province. Hierarchical linear model analyses of survey results from supervisors (n=68) and workers (n=80) revealed that the workers' sense of rapport within the supervisory relationship is related to working satisfaction. While it was expected that the supervisory relationship would also relate to levels of burnout, no association was found in the analyses. However, strong negative correlations were found between the supervisees' feelings of rapport within the supervisory relationship and both emotional exhaustion and depersonalization. The implication of future research and of social work practice and policy were added.

Data production systems are generally very large, distributed and complex systems used for creating advanced (mainly statistical) reports. Typically, data is gathered periodically and then subsequently aggregated and separated during numerous production steps. These production steps are arranged in a specific sequence (workflow or production chain), and can be located worldwide. Today, a need for improving and automating methods of supervision for data production systems has been recognized. Supervision in this context entails planning, monitoring and controlling data production. Two significant approaches are introduced here for improving this supervision. The first is a 'closely-coupledd' approach (meaning direct communication between production jobs and supervisory tool, informing the supervisory tod immediately about delays in production) - based upon traditional production planning methods typically used for manufacturing (goods) and adopted for working with data production. The second is a 'loosely-coupled' approach (meaning no direct communication between supervisory tool and production jobs is used) - having its origins in proven traditional project management. The supervisory tool just enquires continuously the progress of production. In both cases, dates, costs, resources, and system health information is made available to management. production operators and administrators to support a timely and smooth production of periodic data. Both approaches are theoretically described and compared. The main finding is that, both are useful, but in different cases. The main advantages of the closely coupled approach are the large production optimisation potential and a production overview in form of a job execution plan, whereas the loosely coupled method mainly supports unhindered job execution and offers a sophisticated production overview in form of a milestone schedule. Ideas for further research include investigation of other potential approaches and theoretical and practical comparison.
