Work adaptability to a eyehand coordination task with microscopes, and generalization of the studies on work adaptability to tasks of the visual information processing typeKoki MIKAMI, Soichi IZUMI, Masaharu KUMASHIRO, Kazuo SAITO1991 Volume 27 Issue 3 Pages 125-134

JOURNAL FREE ACCESSWomen's work adaptability to a eye-hand coordination task with microscopes was examined compared with men's from the viewpoint of work load and work efficiencies. And also the work adaptability of women in the four tasks of the visual information processing type which had been performed and the predominant characters of women clarified in those studies were synthetically examined.
The obtained results are as follows:
Women's work adaptability to the eye-hand coordination task with microscopes was higher, and their work adaptability to the above four tasks was also higher. As women's predominant characters in this kind of work were suggested (1) high durability of the cerebral cortical activity level, (2) less behavior of escape from work, and (3) in the work requiring knowledge, thought and judgment, increase of their performance and decrease of their errors from the combined effects of (1), (2) and learning effects in the working process.View full abstractDownload PDF (1387K) -

JOURNAL FREE ACCESSThreshold shifts were studied after sniffing at high concentration levels of the odorants. The odorants used in this study were β-phenyel ethyl alcohol (A), cyclopentenolone (B), isovaleric acid (C), γ-undecalactone (D) and skatole (E) of T & T olfactometer. The influence on the thresholds for other odorants (a cross adaptation effect) were examined.
Results:
(1) Cross adaptation effects of the odorant C to A, A to C and D to A are found.
(2) The odorants B, C, D and E, excepting A show no cross adaptation mutually. That may be the four odorants excite different receptors independently.View full abstractDownload PDF (1112K) -
A visual evoked potential studyShin'ichi FUKUZUMI, Toshimasa YAMAZAKI, Ken'ichi KAMIJO, Yoshio HAYASH ...1991 Volume 27 Issue 3 Pages 143-149

JOURNAL FREE ACCESSIn order to evaluate physiologically color readability, the visual evoked potential (VEP) by the display color was examined. Three kinds of dominant wavelength and three kinds of stimulus purity for each dominant wavelength were used as stimulus color for evoked potential. The peak latencies of the VEP by the optical stimulus purity colors obtained by subjective evaluation, was significantly shorter than those by the other colors. Moreover, the larger stimulus purity, the higher the peak potential. From these, it was concluded that VEP peak latency is a quantification of color readability in terms of different stimulus purity.View full abstractDownload PDF (870K) -

JOURNAL FREE ACCESSIn order to obtain motion information of fingers for the motion analysis of hand and fingers, a new method is developed to measure the three dimensional motion of the fingers. The method developed here is based on the pattern matching between the image data of hand and fingers taken with a cine camera and the geometric model constructed within the computer. A software system is developed to extract the motion data of hand and fingers automatically from image data input to the system. The flexion motion of fingers is analyzed to verify the effectiveness of the system. It was proved that the three dimensional motion of fingers can be automatically measured by the system developed. The system has some advantages over the conventional optical measuring methods in terms of accuracy and ease of operation. The system is also advantageous that it can be applied to the overlapped images of fingers.View full abstractDownload PDF (4563K) -
A study on the characterization of the team activityKunihide SASOU, Akihiko NAGASAKA, Takeo YUKIMACHI1991 Volume 27 Issue 3 Pages 159-168

JOURNAL FREE ACCESSIn order to determine the characteristics of the team activity coping with some simulated abnormal operating conditions, this study defined the general idea consisting of “goal” as a team's final purpose, “subgoal” as a team's tentative purpose and “strategy” as a particular plan implemented by a team.
Some subgoals and strategies were determined from the team's behavior under abnormal conditions and classified.
The results showed that there were 2 typed subgoals and 4 typed strategies. Again, the discussion on the features of the subgoal's and the strategy's types by the numbers and the difficulties of each operator's speeches showed that the numbers and the difficulties of operators' speeches depend on the operating conditions which the team is coping with.
This study confirmed that this general idea is usefull when determining the characteristics of the team activity coping with abnormal events.View full abstractDownload PDF (6596K) -
