The ductility factors of nonlinear SDOF systems at Service Limits Ds “using elastic analysis design” in JEAC4601 are investigated, and it was confirmed that the ductility factors depend on the natural frequencies of systems, seismic motions and constant loads. Based on the above results, an acceptance criterion of components to prevent ductile failure and plastic collapse is proposed. The criterion is given as a limit of ductility factor for Service Limits Ds “using elastoplastic analysis design”. The proposed limit of ductility factor allows single state for nonlinear systems, and doesn't depend on the natural frequencies of systems, seismic motions and constant loads.

The electric double layer capacitor (EDLC) electrode is made of carbonized and activated materials. The material surface and electrical characteristics of carbon materials produced from low cost organic materials were examined. First, a cotton cloth was carbonized and activated, and its optimal time and temperature of carbonization and activation processing were examined. And, its surface area, pore volume and pore size distributions were analyzed. Second, activated carbons were applied to the electrodes of 1Wh class EDLC cell with water electrolyte solution. The capacitances and internal resistances of the assembled EDLC cell were measured by a charge and discharge circuit using constant voltage source. And, the charge and discharge cycle test was performed on these assembled EDLC cells under practical use condition. As a result, EDLC cells using the activated carbon with large surface area of 1300m2/g showed the high density of capacitance 0.5-1.1F/cm2. The internal resistances of EDLC cells were less than 0.34W. It was also found that the EDLC cells had no deterioration in the charge and discharge cycle test under practical condition. It shows that the activated carbon made of cotton cloth contributes to the low cost and safety electrode of an EDLC.

本研究は、今日消失の危機にある中国湖南省隆回県における花瑶族の挑花服飾文化を対象としたものである。挑花服飾の制作・使用・廃棄の各様態にみられる資源循環型生活の知恵を再認識することを目的とした。主として現地における聞き取り調査に基づき考察を行った。その結果、挑花服飾文化は、花瑶族の人びとが周囲の自然と寄り添うなかで、自然資源を徹底的に観察し利活用しつつ、主体的に構築してきたものであることを明らかとした。今後にあっては、その確かな理解に基づき、当該地域の生活文化を振興させていくことが求められている。

霞が関の官庁で週に4日、事務職のアルバイトをしています。日給は7700円。でも交通費の支給がなく、税金や年金なども自分で支払うので、手取りで13万円入っても、4万円が消えてしまいます。親との同居でなければ、とてもやっていけません。 天引きで毎月2万円を貯金しているほか、携帯の支払いが月に1万円弱あるので、それ以外が自分で自由に使えるお金ですが、本当に少なくて。

Optomotor reaction has been studied much to examine the visual function of fish. In this study, the optomotor reaction was utilized in order to measure the spectral sensitivity of fish under scotopic conditions, in which two species of cobaltcap silverside and medaka were investigated. Light of various wavelength was irradiated for the fish which had been fully adapted in the dark and the optomotor reaction of the fish was observed. The optomotor reaction developed more slowly in the darkadapted fish than in fish adapted in the irradiating light. When light of a wavelength giving an absorption maximum for the rod visual pigments of the fish was irradiated, the inhibition of the optomotor reaction was greatest. Thus, the spectral sensitivity curve for the optomotor reaction of dark-adapted fish coincided well with the absorption spectrum of the rod visual pigments in both the species of fish. The usefulness of this behavioral method for ascertaining the spectral sensitivity of fish under scotopic conditions was discussed.

A 30-year-old woman was admitted to our hospital with high fever and chest pain. She had a ventricular septal defect, but was asymptomatic and had not undergone surgical repair. She also had had atopic dermatitis since childhood that had not been adequately treated. Chest computed tomography showed multiple peripheral nodules and infiltrates in both lungs. A transthoracic echocardiogram detected vegetation on the wall of the right ventricle, and Staphylococcus aureus was cultured from a peripheral blood sample. She was diagnosed as having a septic pulmonary embolism associated with right-sided infective endocarditis caused by S. aureus. She was treated with Cefazolin, resulting in gradual improvement of laboratory and chest radiographic findings. Recent studies have revealed that atopic dermatitis is one of the risk factors for infective endocarditis. In this case, uncontrolled atopic dermatitis might have caused the right-sided infective endocarditis.
