Consideration about Method of Presenting Art Work in Educating Comparative Appreciation

本稿では、筆者の提示する「対照性と類似性を基軸とした比較による鑑賞教育方法論」の展開として、比較鑑賞教育法における美術作品の提示方法について考察した。そこではまず、鑑賞教育に関する大規模調査の結果をもとに、鑑賞教育の普及の実態について考察し、作品の提示方法という鑑賞教育における基礎的事項が、鑑賞教育普及上の実際的な問題であることを指摘した。そして、複製を主とした比較鑑賞における作品提示方法を、作品の提示媒体と提示形態に分けて、それぞれを類型的に考察しその特質を論じた。この後、これらを組み合わせて、比較鑑賞における作品の提示方法について考察した

Single sheet tester having open magnetic path for measurement of magnetostriction of electrical steel sheet

A single sheet tester having closed magnetic path (a closed type of SST) has a problem that measurement accuracy of magnetostriction is considerably affected by electromagnetic force between specimen and yoke. Therefore, an open type has been developed. In order to get uniform flux distribution in a sufficiently large region, a compensating magnetizing winding is installed, and a method of waveform control is investigated, in which applied voltages to main and compensating windings are adjusted individually. The effectiveness of the newly developed open type is demonstrated by measuring magnetostrictions of thin amorphous sheet as well as highly grain-oriented silicon steel sheet</p

Measuring System of Magnetostriction Under AC Excitation Using Optical Methods

A measuring system for magnetostriction of silicon steel sheet using optical methods and a single sheet tester has been developed to establish a standard test method for IEC and JIS. Various factors affecting measurement accuracy and reproducibility of the developed system are examined. Two optical instruments, such as a laser Doppler vibrometer and a heterodyne displacement meter, are compared. 3-D characteristics of magnetostriction under ac excitation in the rolling direction are measured up to 2.0 T </p

Recyclable Magnetic Nanoparticle‐Supported Iodoarene Catalysts for Oxidation of 4‐Alkoxyphenols to Quinones

Iodoarene catalysts immobilized on magnetite (Fe3O4) were developed. The reactivity of catalysts 4 a and 4 b were similar to that of 4‐iodophenoxyacetic acid (3) for the oxidation of 4‐alkoxyphenols in the presence of Oxone® as a co‐oxidant to give the corresponding p‐quinones in high yields. In addition, 4 b was readily recovered by the use of an external magnet and was recycled up to eight times. This is the first example of a magnetic, nanoparticle‐supported iodoarene catalyst.Drawn to it like a magnet: The reactivity of iodoarene catalysts immobilized on magnetite (Fe3O4) were similar to that of 4‐iodophenoxyacetic acid for the oxidation of 4‐alkoxyphenols in the presence of Oxone® as a co‐oxidant to give the corresponding p‐quinones in high yields.

Stereoselective Total Synthesis of Myriocin Using Rh(II)-Catalyzed C–H Amination Followed by Alkylation

The stereoselective total synthesis of myriocin was achieved by using the Du Bois Rh(II)-catalyzed C−H amination of sulfamate 6 and a subsequent alkylation. The reaction of sulfamate 6 with PhI(OAc)2 and MgO in the presence of Rh2(OAc)4 gave oxathiazinane N,O-acetal as the sole product in high yield. Alkylation of the N,O-acetal using vinylmagnesium bromide in the presence of ZnCl2 proceeded stereoselectively to provide an oxathiazinane bearing a quaternary chiral center in high yield. This route includes the first application of the Du Bois procedure for the construction of a quaternary chiral center

Bipedal Robot Running: Human-like Actuation Timing Using Fast and Slow Adaptations

We have been developing human-sized biped robots based on passive dynamic mechanisms. In human locomotion, the muscles activate at the same rate relative to the gait cycle during running. To achieve adaptive running for robots, such characteristics should be reproduced to yield the desired effect. In this study, we designed a central pattern generator (CPG) involving fast and slow adaptation to achieve human-like running using a simple spring-mass model and our developed bipedal robot, which is equipped with actuators that imitate the human musculoskeletal system. Our results demonstrate that fast and slow adaptations can reproduce human-like running with a constant rate of muscle firing relative to the gait cycle. Furthermore, the results suggest that the CPG contributes to the adjustment of the muscle activation timing in human running.Comment: 15 pages, 12 figures, submitted to Advanced Robotic
