  • This study is planned to investigate the attitude toward the safety and health management of contractor company. Under the contract based production system, all of activities including safety and health management in the contractor company are depended upon the contract. How to make contract influence the worker's health of contractor company. Worker's health of contractor company can be protected by efforts of company of contract-out and contractor company, especially their safety managers. The modelling of the effective safety and health management system for contractor company should consider the need of safety manager of each company and employer of contractor company. Data is collected from safety managers of 3 contract out compaines as electronic and electrical manufacturing industry and 55 safety manager, 57 employers of their contractor compaines using self administered survey with structured questionnaire. The most of all respondents want to support from the contract out compaines. The most important items supported from contract out company is the information based on the safety information network between each company. Safety manager and employer of contactor company also itemized safety education and training in the supporting system from contract out company. These results can be generalized to survey on the other industries.

  • This paper deals with parameter tuning of the Power System Stabilizer (PSS) for 612 MVA thermal power plants in the KEPCO system and its validation in a field test. In this paper, the selection of parameters, such as lead-lag time constants for phase compensation and system gain, is optimized using linear and eigenvalue analyses. This is then verified through the time-domain transient stability analysis. In the next step, the performance of PSS is finally verified by the generator's on-line field test. After the field test, measured and simulated data are also compared to prove the effectiveness of the models used in the simulations.
