Adhesion is one of essences with respect to rubber friction because the magnitude of the friction force is closely related to the magnitude of adhesion on a real contact area. However, the real contact area during sliding depends on the state and history of the contact surface. Therefore, the friction force occasionally exhibits rate-, state-, and pressure dependency. In this study, to rationally describe friction and simulate boundary value problems, a rate-, state-, and pressure-dependent friction model based on the elastoplastic theory was formulated. First, the evolution law for the friction coefficient was prescribed. Next, a nonlinear sliding surface (frictional criterion) was adopted, and several other evolution laws for internal state variables were prescribed. Subsequently, the typical response characteristics of the proposed friction model were demonstrated, and its validity was verified by comparing the obtained results with those of experiments conducted considering the contact surface between a rough rubber hemisphere and smooth acrylic plate.

This paper investigates the walking performance of a thermal walker on various inclined surfaces. The thermal walker can walk only by ground heat energy using bimetal sheets. The walking performance on slopes is analyzed using a simplified walker model. The analytical result is compared with the two sets of walking experiments, on slopes with either pitch or roll inclinations. The analyses and the experiments are done with different Center-of-Mass (CoM) positions of the legs, which considerably influence the walking performance. It was found that, on up/down slopes, the stride of the thermal walker changes almost linearly with the slope angle. When the CoM was close to the center of the walker body, the walker walked backward on upward slopes. With CoM largely shifted backward, the walker could walk up slopes but did not walk down slopes well. On the other hand, when walking along a contour line of a slope, the stride decreased as the slope angle increased. The smaller leg swing distances would be caused by the change of leg swing time on such slopes.

＜正＞ Recently, shape memory polymer （SMP） as one of functional materials has received much attention and its mechanical properties have been investigated. Shape memory polymer of polyurethane series has the glass transition temperature （Tg） around the room temperature. According to the large change in modulus of elasticity above and below Tg, the SMP material has excellent shape memory effect. In this study, the glass fiber reinforced shape memory polymer was developed for the improvement of the mechanical weakness of SMP bulk and for wider applications. It was clear that the improvement of the resistance to creep and cyclic loading in the composites with SMP was obtained due to reinforcement fiber.

AIM: To describe a new surgical technique and evaluate the early results of segmental gastrectomy (SG) with modified D2 lymph node (LN) dissection for early gastric cancer (EGC). METHODS: Fourteen patients with EGC underwent SG with modified D2 dissection from 2006 to 2008. Their operative results and postoperative courses were compared with those of 17 patients who had distal gastrectomy (DG) for EGC during the same period. RESULTS: Operating time, blood loss, and hospital stay were similar between the 2 groups. Postoperative complications developed significantly more frequently in the DG group than in the SG group. Mean number of dissected LNs per each station in the SG group was comparable with that in the DG group. Postoperative recovery of body weight was significantly better in the SG group than in the DG group. The incidence of reflux esophagitis and gastritis after surgery was less frequent in the SG group than in the DG ***: SG with modified D2 LN dissection may be a new function-preserving gastrectomy that is feasible for treatment of EGC with possible LN involvement.
