Physical motor function and nutritional assessments were performed before and 3 to 6 months after the start of the intervention. The Holmʼs multiple comparison procedure was used for the statistical analyses. The patientsʼ quality of life (QOL) was evaluated before and after the intervention and compared using the Wilcoxon signed rank test, with p values of ＜0.05 considered significant. Physical motor function was assessed based on grip strength (non shunt limb), knee extension muscle strength, toe grip strength, and abduction muscle strength at 3 months after the intervention. The subjects exhibited improvements in muscle strength and the results of the 30 second chair stand test and 6 minute walking test after 3 months, which were maintained after 6 months. No significant changes in nutritional parameters, including the blood hemoglobin concentration, were observed. The QOL evaluation revealed that physical function, mental health, the subjectsʼ overall view of their health, and vitality increased. It is pre-

The Scanning Transmission Electron Microscope (STEM) can provide images beyond Scanning Electron Microscope (SEM) capability, on samples which do not have to be prepared to the degree required for Transmission Electron Microscopy (TEM). For some applications, such as semiconductor production, speed of analysis is critical. This paper explores Focused Ion Beam (FIB) sample preparation for STEM.The samples were prepared using an Hitachi FB-2000A FEB tool. Two analysis regions of similar thickness were cut. The rough sample was milled using a 500 pA beam and no polish cut. The smooth sample was prepared by cutting first with a 500 pA beam, and then using additional, smaller diameter beams, concluding with a 30 pA beam. This resulted in a sample surface polished to a degree similar to that used for TEM specimens. The samples were imaged in an Hitachi HD-2000 STEM at 200KeV. Transmission electron images taken at 100 kx are shown in Figure 1 of the rough sample and of the smooth sample.

<p>As a repair for corrosion damage of a steel bridge, a patch plate-repair using high strength bolts is generally applied. This method requires the surface of the damaged corroded part filled with an epoxy adhesive flat. The load transferring mechanism and slip resistance of such a combined joint with adhesives and high strength frictional bolts aren't clear. Since the shear strength of an adhesive might be increased due to constraint by the bolt axial force, the combined joint's slip resistance would be increased. To clarify the mechanical properties of the combined joint and to propose a new design method for such joints, two experiments have been conducted. The first was a frictional force experiment for adhesive specimens subjected to contact pressure on the surface to evaluate the constraint effect of adhesive on shear strength quantitatively. The last one is a slippage experiment for the combined joints to evaluate its slip coefficient.</p>
