We developed a safety education program consisting of three experiential education subprograms, “Confirmation of Rules”, “Human Error Experience” and “Role Play Experience”, aiming at deterring violation of “double check rule of train schedule diagram” in railway maintenance work and promoting compliance with the rule. In this program, after the employees are educated about “Confirming the Rule”, they are educated the reasons of the rule with “Human Error Experience” and “Role Play Experience”, to improve the rule compliance attitude. Twenty-four site managers became the lecturers at their own workplaces and tried the program with 263 on-site employees as the students. As a result, 95.8％ of the lecturers and 88.2％ of the students made positive evaluation of the significance of the entire program. After the program was implemented, the rule compliance attitude of the students was significantly improved at 1％ level. In addition, the sense of burden imposed on the site managers in charge of the lecturer was within the operational permissible range. From these results, it was confirmed that the developed safety education program is effective for deterring violation of the rule and can be adopted at each work place.

The present study aimed to understand changes in visual search strategies before and after intervention, in addition to examining the training effect of Multiple Object Tracking （hereafter MOT） skills. Participants were 29 male university baseball players. They were grouped into the training group （Group T; 19 participants） and the control group （Group C; 10 participants）. The three-week intervention comprised MOT tasks. As a result of the intervention, significant interaction was observed between the groups as well as before and after intervention. Group T showed a significant increase in scores of the MOT tasks after intervention as compared to those before intervention. Subsequently, we examined the changes in visual search strategies among six participants with a large training effect （LTE group） and six participants with a small training effect （STE group）. Consequently, the gaze travel distance of the post-intervention LTE group was short and the travel speed of the stationary point was large, which was interpreted to have a moderate effect size without a significant difference. These results suggest that for university baseball players, MOT skills can be acquired by training. Furthermore, we did not see any clear change in visual search strategies brought about by MOT skills training.

Nonverbal communication via touching affects human emotions. This study aims to investigate the effect of robotic touch on human emotions. Russell's circumplex model that explains human emotions along orthogonal arousal and valence axes was employed for the investigation, and three principal motions （grasp, tap, and stroke） were implemented to investigate the human emotional response to touch. The results showed that human emotions were affected by the touching speed and pressing force of a robotic touching unit. To cause desirable emotions, motion parameters were designed based on experimental results and employed to examine the emotional response to the motions. The arousal responses could be predicted by a superposition of the responses of the three principal motions.

Extracting the working posture of different trend （anomaly posture） using anomaly detection helps to understand the problems of posture in the work tasks. This study proposes the extraction method for anomaly posture using One-Class Support Vector Machine. The proposed method was applied to the screw tightening tasks in various working positions and heights near the body on twelve participants. During the tasks, Euler angle of each body segment, joint angle and calculated joint torque ratio were recorded, and the participants were questioned about their subjective evaluation. The proposed method calculated the ratio of extracted anomaly posture under several settings of the hyperparameter and the specific vector. In the near and central work position, subjective difficulty of the work increases while does not show the relationship to the joint angle and joint torque ratio. On the contrary, the proposed method shows the relationship of the ratio of extracted anomaly posture to subjective difficulty when the hyperparameter ν, which is upper bound on outlier, set to 0.10.
