We developed a HPMA Information System to establish the voluntary safety management for the Paint Industry. HPMA System means that manager, supervisor and worker on the process-line find out the hazardous and/or unsafe potentials, make improvement of the field safety by the cooperation with top manager, safety staff and eventually put in the practice. HPMA Information System consists of functions to suggest and evaluate the safety concerns hierarchically from top manager to workers on internet or intranet. We establish the safety management and sharing of the safety information and are able to find the unsafe potentials by the HPMA Information System. Also We are able to mine new safety information and establish accident prevention model by the Safety DATABASE.

The aim of this study is that HPMA(Hazard Potentials in My Areas) System is to present for establishment of the voluntary safety management on industrial region. HPMA System Itself means that manager, supuryisor and worker on process-line find out the hazardous and/or unsafe potentials from their work places and make the plan of improvement by means of mutual communication with top manager and the department of safety staff, eventually put in the practice. In case that it takes the longer time to improve hazard potentials and is impossible improvement by existing technique, appropriate check-list will be used by the worker himself on the identified production line. Form this system, therefore, it makes them to get more and more sensitivity to the hazards. In this study, we present the voluntary safety management system which is controlable systematically and in the final analysis the direction of safety management by computerization of HPMA System which is activated in their work places.

Poly (HPMA/NVP) hydrogel was synthesized according to the composition and the con- centration of the crosslinking agent. The swelling degree of the P(HPMA/NVP) hydrogel decreased with increasing of P(HPMA) composition and crosslinking agent. The glass transi- tion and softening temperatures of the P(HPMA/NVP) increased with increasing of P(HPMA) composition. The composition of P(HPMA/NVP) : 70/30 and the concentration of the crosslin- king agent of 0.5 wt % gave the optimum condition in the application to the contact lens. There were also adequate in the mechanical, refractive properties and in vivo test in the P(HPMA/ NVP): 70/30 system.

Interest to the RTLS is increasing recently, and the RTLS is used in various fields. It is one of applications for locating and tracking using RFID tags which are attached to something like container, pallet, or all thing. In this study, a RTLS system was developed for efficient safe management in chemical industry. This system could manage dangerous substance and a personal history regarding entry. Detailed results of this study are as follows: (1) Through RTLS entry management system which is developed this study, the events along a movement of dangerous substances and the person in charge could be grasped and recorded. (2) A user, goods and a warehouse could be managed and monitored efficiently as using the developed RTLS history system. (3) RTLS system will contribute to efficient safety management of the chemical industry. Besides, RTLS system might be applied to the other industries like shipbuilding and car industry.
