In this study, the skill of automotive engineers in sheet metal repair is analyzed. Because no two damage situations are identical, every damage is reconsidered on a case-to-case basis, and flexible responses are required. This work requires considerable human technical skill and relies on experienced workers. When the skills depend on experience, human resource development is essential to impart such skills. The overall objective of this research is to propose a personnel training tool. The fender of an automobile was repaired by workers by a sheet metal working technique. The results showed that the experts initiated their strikes in the peripheral part of the dents. Thereafter, they applied several broad strike patterns in their repairs: for example, avoiding striking the peripheral part of the dent; striking the central part while avoiding the press line, followed by striking both the peripheral and central parts; and applying many strikes on the press line in the central part of the dent.

In this study, we engaged veterans of both nursing and care work, measured their movement during body position changing and wheelchair transfer, and examined the characteristics of movements of each subject. In general, the location where a nurse conducts the movement in discussion is a hospital ward. On the other hand, it would normally be a facility such as a nursing home for a care worker. Between a hospital ward and a care facility, there are many differences such as the legally required size of a room or the fact that one place is for medical treatment and the other is for living, resulting in dissimilarities such as the positioning of beds. By exploring the difference in the movement of nurses and care workers, while taking these factors into consideration, it is possible that improved methods for body position changing and wheelchair transfer that are better adapted to the environment could be devised.

Laparoscopic surgery is thought to be more difficult to acquire the surgical technique compared with conventional one. Eye movement differences between novices and experts have been shown in the various fields. However, a few papers compared the eye gaze movement behavior of novice and expert surgeons during performance of a laparoscopic surgery task with a simulator. The examinee operated the same case of the laparoscopic cholecystectomy of the simulator, and the eye movement detection method was a pupil corneal reflection method. The expert operator showed economical hand and eye movement compared with novices. Once their act change to a camera operator, their gaze behavior seemed to change to the trainer’s one. The medical students improved to shorten the duration time in procedure in one week of training, however, the gaging pattern did not change. Using this eye tracking system, the new educational system can be established to train the medical student, novice surgeon, and also expert surgeons as trainer.

The objective of the present work is to fabricate Urushi-like glass fiber reinforced plastic (GFRP) by using black silk fabric. We first manufactured a GFRP molded plate consisting of various laminate layers, and compared the surface color with that of Urushi products. Subsequently, we used impression evaluation to reveal how the GFRP plate fabricated using the black silk fabric was rated. The study results confirmed that L* and a* values of the GFRP sample were similar to those of the Urushi sample. In the impression evaluation, almost half of the subjects considered the GFRP sample fabricated using the black silk fabric (with lightness similar to that of the Urushi product) as the original Urushi product. The subjects also associated more “beauty,” “sense of luxury and high quality,” and “depth of blackness” with the sample regarded as the Urushi product than with the sample not regarded as the Urushi product.

In this study, the striking motion of an expert’s hammer during the sheet-metal molding process in an automobile repairing process was analyzed and compared with those of non-experts. As the first step, the study attempted to examine the characteristic motions of experts performing such a task. Using a three-dimensional digital motion analysis equipment, we measured the movement of skilled and unskilled individuals while repairing cars by using the sheet metal molding process. The results showed that the total time spent for ‘hammering,’ ‘others,’ and ‘total work time’ by the experts was significantly shorter compared to the time spent by non-experts. Furthermore, experts were able to complete the task with one hammer. Additionally, experts used a lower number of strikes compared to non-experts as the hammering time increased.

"Yuzen" is a traditional but still popular method of dyeing fabrics in Japan. The products using the Yuzen method and manufactured in Kyoto city are called "Kyo-Yuzen." The dyeing method of Yuzen can be dividing into 10 procedures. A specialized craftsman is in charge of each procedure. During the paste application (Nori-oki) procedure, the expert applies a starch paste or a rubber paste to a fabric in order to resist dyeing. The two resist pastes create different effect on the dyed fabric. At market, the fabric with a starch paste application is perceived to have a higher value than that with a rubber paste. In this study, the difference of the viscosity between two materials was clarified, and specimens which craftsman dyed were observed. Then how two materials put on fabrics, and the structures of them were measured. As a result of this research, it was clarified that rubber paste penetrated into fabrics rather than starch paste.
