Requirements for pens have changed markedly as a result of individual writing environments and writing features. That is, today is marked a demand for pens to provide ‘ease of use’ and ‘ease of writing’, although these aspects differ vastly among individuals. This research sought to construct a model to provide suitable pens to individuals. This research focused on writing pressure as generally reflects characteristics like the size of the hand, grasping posture, anatomy, and habits. Thus, we constructed a model that allowed prediction of an individual’s writing pressure using fuzzy inference and suggested a pen suited to the individual depending on his or her writing pressure. As a result, entering the length of the forefinger, the height of the fourth contact point, and the height of the middle finger contact point selected a pen tailored to the individual depending on his or her writing pressure; this allowed a model for more ergonomic pen selection.

The number of multi-functional self-service terminals (MSTs), such as auto-teller machines (ATMs), ticket-vending machines, and automatic load contract machines (ALCMs), has been increasing with the growth of user’s convenience needs. However, they are quite often criticized about software usability (interactions) because of their operational complexity.
Special interest is that addition of the automatic loan contract function influences software usability of MSTs. By analyzing usability testing (user tests) data of seven subjects, this paper shows limitations of the application of current ATM designs to ALCMs and proposes four new guidelines. The second test shows effectiveness of the proposed guidelines in the evaluation of screen designs of ALCMs, followed y the discussion of future issuers.

Unilateral spatial neglect is one of the severe sequelae of stroke. The evaluation of the severity has been performed by Behavioural Inattention Test, Albert’s deletion, reproduction of pictures, etc. on a sheet of paper. In this paper, we propose a novel approach using a personal computer with a touch panel display. We found that the time analysis of patients’ behavior gave more sensitive diagnosis than the paper test.

When pregnant women have a caesarean section under lumber anesthesia, most of them develop low blood pressure because of a hyperbaric anesthetic. The purpose of this study is to demonstrate the preventive effect of a 20 centimeter footrest to raise their legs after beginning lumber anesthesia on low blood pressure. Out of 33 pregnant women, 17 raised legs and 16 did not. The average time before administration of drip containing a vasopressure (neosinejin: vasoconstrictive) was 4.7  3.9 (n = 17) minutes in intervention group and 5.3  10.6 (n = 16) minutes in control group. The average duration of a drip was 18.8  8.7 (n = 16) minutes in control group and 9.9  9.4 (n = 17) minutes in intervention group, about half as much. The total hemorrhage average during an operation had no statistical difference between intervention group and control group, 2740.0  333.3 (n=17) and 2704.5  493.2 (n = 16), respectively. This study suggests that raising legs of pregnant women has a preventive effect on low blood pressure without increasing bleeding under lumber anesthesia.

Recently, the end user comfort on seating has developed into an important issue. In this context, the studies on sitting comfort have increased its importance. Body pressure distribution is one of the most common measurements to evaluate sitting comfort, and it is said that this measurement appears to the objective measure with the most clear association with the subjective ratings. Many of the researchers have reported the relationship between seat comfort and body pressure distribution, and most of the reports concentrate on short-term and stable sitting. However, when evaluating seat comfort, especially seat cushion comfort, body movements and re-sits are often seen. It was considered that the change in condition of contact between seat and human body is important for evaluating seat comfort and discomfort. This paper was focused on the change of pressure distribution during sit-down motion, and the relationship between seat comfort and discomfort was discussed. Two hundred and ten volunteers participated on this research, and the result showed some characteristic changes in pressure patterns on comfort and discomfort conditions. The findings of this research would give some useful information for providing comfortable seats/chairs in th future.
