Purpose: To clarify how reception and action regarding the relation between the object (an ampule) and the body are divided and organized, and whether or not the expertise action is composed using video and sound analysis. Method: Study Subjects: 2 student nurses and 2 nurses Data collection method: For video data, ampule cutting scenes were videotaped. For the sound emitted when ampule cutting, a sound analysis system, 'Movelet,' was used. Data analysis method: For video data, the action composing ampule cutting such as the ampule holding method and posture was categorized and identified, and the body movement leading to the action, the relation among perception and action, and the organizing characteristics were extracted. For sound data, the waveform area of the high frequency bandwidth sound emitted when ampule cutting was calculated. Results: For nurses, the balance of right/left forearms, upper arms, and fingers was stable, and they did not even look at their hands. The ampule cutting action of nurses was very smooth, and individual action was continuous, overlapped each other, and rhythmical. On the other hand, students checked the surface of the ampule with their fingers and changed the holding angle several times before cutting the ampule, and also stared at their hands from the start to the end of ampule cutting. Forearms, upper arms, and fingers of the students were away from their bodies and also unstable. The comparison of sound data emitted when cutting the ampule showed that the sound nurses created when force was applied to an ampule was short, and the ampule was cut with one-time force application. On the contrary, the sound created by students was long, and the force applied to an ampule was distributed. Considerations: The 'ampule cutting' is an action which requires sensing sensations through the body along with maintaining overall balance of the right/left forearms, upper arms, fingers, and positions depending on the senses (visual and haptic systems). These characteristics were different from the physical basis conventionally employed for nursing technical training. It is expected to improve the expertise of trainees' action by focusing on the reality of perception and action, concentrating on sensory correction during repetitive practice, changing action during the negotiation with the "thing" or "object," and supporting the trainees' abilities of searching for the best action.
