Several metrics have been used in crash discrimination algorithms in order to have timely airbag deployments during frontal crashes. However, it is still challenging to have timely airbag deployments during oblique crashes, pole crashes and underride crashes. In this paper, a new crash discrimination algorithm was proposed, using the deceleration squared multiplied by the velocity change as a metric. The new crash discrimination algorithm resulted in appropriate time-to-fires for many modes of frontal crashes. In this paper, the deceleration pulses measured at the left and right B-pillar' rocker locations during oblique and offset crashes were also processed to determine the time-to-fires of the driver airbag and the passenger airbag. The deceleration pulses resulted in appropriate but different time-to-fires for the driver airbag and the passenger airbag, and this implies feasible accelerometer locations especially for an advanced airbag system.

In the construction industry, due to the nature of the job, the need for job training to maximize the performance of the job and to improve the organization's qualifications is needed to acquire professional knowledge that is practiced according to the training needs of the members of the organization. In the form of education, the government or the government or the government provides systematic and planned professional job training that is implemented to improve qualifications and instill pride in the profession by helping the employees of the design office acquire new knowledge, skills, and attitudes necessary for professional performance. Although it is recommended at the organizational level, as a result of examining the implementation, it was found that most workers did not receive job training activities. Therefore, follow-up studies that can maximize work efficiency at the individual and organizational level of design office workers should be continuously performed.
