If we were reviewing safety standards in Korean businesses today we would find that conglomerates have a low rate of workmens accidents largely due to safety supervision being practiced on site. Unlike small businesses which experience more than 50% of the total workmens accidents with many conventional accidents occurring repeatedly. This research is presenting a course that proves safety and health programs are the most effective positive factor to increase a companys prosperity. This model research also presents basic causes of industrial accidents and has made counter proposals by trial modeling.

Plant is production unit which consists of hardware for manufacturing like machinery, equipments and software for its installation like design, construction, supervision, engineering, know-how and trial operation. In the view of this, plant industry can be defined as an aggregation of manufacturers and sellers of plant. In this study, I would like to present the direction of cooperation for mutual benefit of Korea-Japan by understanding international competitive power of both countries' plant industry, which is not only growing as a national strategic industry, but also occupying the most important part in international economic cooperation.

This study restoration worker for dispersion relay in R-Type fire alarm system. Restoration worker very good instrument for an fire system inspector. When inspector check for fire system someone need reset for fir system to normal state. This chain of action is frequent and troublesome. In this case, If we can automatic reset for fire system it's restoration worker. This paper settlement on the problem for reset fire system. Design, make grabber for restoration worker. The test offer proof possibility restoration worker.

For protection of power system, it is a prerequisite to action characteristics of protective relay about a changing environment in power system and correcting the setting value. A substation operator always reside to correct of a relay, however there are problem of efficiency. Recently, power system operation become manless and supervision and control of incident is required anywhere, introduction of new concept as a intellectual manless protective relay is a recent trend. This paper is the web-based protective relay setting program that a manager make an analysis of operation and incident of power system through the web at a remote place corresponding recent manless of system and approach the protection relay and then can correct the error.

Recently, fundamental innovation for the improvement of Korean railway industry is proceeding with the vertical separation into infrastructure and operation, and the privatization of railway operation. And also, with the advent of an era of high-speed railway, starting of Korea Train Express (KTX) will give a great change to circumstances of railway industry. It requires that a railway safety regulation policy and accident survey system cope effectively with this restructuring of railway system. Under these great changes, safety must have the first priority, and the function of management and supervision on railway safety will be ten to the governments responsibility; In this paper, according to changes of railway safety management system, foreign states railway accident system and direction of korea railroad accident survey system will be also introduced.

Based on the design of the LIS of GuangZhou and BeiJing, this paper discusses the resolution of the LIS with the kernel of process management. It applies the idea of workflow in the management supporting stratum, applies the process-oriented mechanism in the definition, coordination, supervision and control of the management process. The scheme has the character of information-media-oriented, work process dynamic changing supported, application system extended and restructure supported and is independent of the running environment of specific work.. Due to the previous character, the LIS is flexible, useable, elastic and able to support the dynamic application.

To achieve the safety and reliability, RAMS activity for a railway signal system of Near Surface Transit is studied. In this paper, preliminary hazard analysis in RAMS activities is studied for the railway signal system of Near Surface Transit. Preliminary hazard analysis is done through automatic train protection, automatic train operation and automatic train supervision. The hazards are defined, then causes and consequence for each hazard are defined. The total 75 preliminary hazards are classified. For high severity hazards are changed to acceptable level by upgrading of system requirement specification.

A ball moving on a beam is a typical nonlnear dynamic system, which is often adopted to proof test diverse control schemes. Ball and plate system is the extension of the traditional ball and beam problem that moves a metal ball on a rigid plate. In this paper, a trajectory planning and tracking problem is proposed for ball and plate system, which is to control the ball from a point to another without hitting the obstacles. Our scheme is composed of three controllers, TS type optimal path tracking controller, mandani type obstacle avoidance controller and trajectory planning controller that determines the desired trajectory. But this type of construction can give rise to chattering executions. Because the difference of contributions from concurrent controllers can cause behaviors unsmoothly. We propose fuzzy pid supervision control1er to handle this problem.

In this paper, we have studied for development of unmanned remote supervisory system using mobile communication network, not wire network, not to be affected by space or distance. The unmanned remote supervisory system consists of data processing unit main part and measuring systems (modules part)-temperature measuring module, humidity measuring module and human body sensing module. The data processing unit to collect and process informations of each measuring module has the functions of data communication between a mobile cellular telephone and measuring systems. Each measuring module has supervisory and warning functions for a target of supervision. And then we have designed each system and evaluated accuracy and reliability of the combined total system.
