It is said that a large part of losses caused by company is attributet to the loss manpower material resources by industrial accident. To alleviate industrial accident, machine-oriented safety supervision is superior to that of manpower-oriented in spite of diversified efforts, in many aspects. It will not secured a sense of safety if people can not utilize machines correctly despite excellent machines. As a part of preventing industrial accident, industrial safety education is aimed to improvement of productivity of company through exact research of actual condition of industrial safety education.

A supervisor's role is very important to have accident free environment in a company. In order to take full advantage of safety management system, company safety supervisors require to learn how much responsibility they have in their company. To improve safety supervisor's knowledge, they must spend time to learn the importance accident free environment. To improve the efficiency of safety management, the supervisors need to voluntarily emphasize the importance of safety management.

기업에서 발생되는 손실 부분 중 커다란 부분을 차지하고 있는 것이, 산업재해로 인한 인적ㆍ물적인 손실이라고 할 수 있다. 산업재해를 줄이기 위한 방법으로 여러 가지 측면에서 다각적인 노력을 기하고 있으나 현재 기업의 산업안전에 관한 실태를 살펴보면 인간중심의 안전관리보다는 기계중심의 안전관리가 더 우월하게 이루어지고 있는 실정이다. 문명의 발달로 아무리 기계기구로 좋아졌다 하더라고 그것을 사용하는 인간이 제대로 사용할 수 없다는 안전성은 확보 될 수 없을 것이다. 산업재해를 예방하기 위한 방편으로 기업 내에서 실시되는 산업 안전 교육부분에 대한 정확한 실태 조사를 통해 산업안전교육이 기업 내에서 효율적으로 자리잡아 기업의 생산성 향상에 도움이 되고자 한다.

As the manufacturing systems adapt information technology, safety control and management systems are required to adapt information technology by changing the industrial environment. This paper is presented the methodology of designing the safety control and management system based on intranetwork environment to reduce breakdown time on facility and Increase efficience of safety training and education.

Here we introduce so called Reference code-weighted sum of all PN codes used in the system-. We do inner product operation between received PN code and Reference code rather than locally generated PN code in the receiver. Acquisition process can be accomplished by only one inner product during full period of PN code. It's essential innovation against present method which can be viewed successive hypothesis test by inner product for entire candidate PH codes set. Well -defined decision region makes it possible. We suggest the. criterion fur designing the decision region and find a condition for weight (coefficient) of Reference code.
