For preventing accidents resulted from human errors in large-scale complex systems, operator personnel is required to learn not only Technical Skills (TS) but also Non-Technical Skills (NTS). However, it may be difficult for many industrial domains to develop and introduce comprehensive NTS training like Crew Resource Management (CRM) training in the aviation domain due to resource limitation. Therefore, simplified and generalized training methods of NTS are necessary for the purpose of bringing the safety benefits of NTS to wider industrial domains. For the first step to realize such NTS training, this study developed an experiment environment for examining the effectiveness of NTS skills derived from a specific industrial domain in generalized task context, focusing on communication skills which are regarded as fundamental skills of NTS. The experiment environment was evaluated through the effectiveness assessment of communication skills derived from the aviation domain. The experimental environment can contribute to the development of effective generalized NTS training program by supporting the identification of fundamental common communication skills.

It is common to evaluate automobile seats with the objective values like transmissibility. In such conventional evaluation methods, psychological factors of occupants have not been considered even though occupants eventually judge ride comfort. In this paper, we executed the driving simulator experiment to investigate the applicability of the evaluation by the subjective score as well as the objective value to ride comfort evaluation of automobile sear. In the experiment, five kinds of test seat were randomly fixed on the driving simulator, and twenty participants drove on the test course where the whole body vibration was exposed. We measured the vibration accelerations and obtained discomfort rating of the participants. From the experimental results of the scaling with the vibration accelerations and the participant's discomfort rating, we could show particular characteristics of the test seats. Since some previous studies reported that the measurement of the whole-body vibration based on ISO2631-1 has many problems, we recognized that we should explore the measurement of the whole-body vibration as well as continue the seat evaluation experiment under another course layout where the rolling and yawing vibration is exposed to participants.
