レンブラント「夜警（1642年）」の鑑賞題材化（7段階鑑賞学習プログラム）の試みI : 集団肖像画の読解的鑑賞の一局面（観察・記述と自由解釈を中心に）
No full text本稿は連稿前篇である。絵を見て読む，その複合的学習過程で感性・読解力・言語活用能力・美的批評眼等を総合的に養うことを狙う「読解的鑑賞」と，日本の中学生の西洋絵画（異文化体験的対象）との邂逅を契機に促そうと努める，「美術を通した西洋理解」の2つを，本稿の基柱と考える。バロック期からレンブラント「夜警（1642年）」を選定し，その鑑賞題材化の諸可能性を検討した。作品調査で収集した情報を土台に，さらには神林恒道の「夜警」鑑賞手引き，堀典子が社会的・歴史的観点から「夜警」解読に迫る鑑賞授業実践報告も参照し，鑑賞題材構想を具体化した。結果的にE. B.フェルドマンの4段階批評法を基盤に7段階・15項目で成る鑑賞学習プログラムを組織でき，本稿ではその第1段階「観察」と第3段階「解釈」を巡り論述した。残る第2段階と第4段階以降の考察は後篇に回し，最終段階で示した補充課題5個も次稿で詳述したい。Article美術教育学研究.50(1):121-128(2018)journal articl
Airway obstruction due to a laryngeal polyp following insertion of a laryngeal mask airway
No full textBackground: Laryngeal mask airway (LMA) insertion contributes to airway protection in patients with a laryngeal tumor around the glottis. There has been no report of LMA insertion itself exacerbating airway obstruction in such patients. Case presentation: A 62-year-old male underwent elective surgical resection of a large laryngeal polyp. The polyp was attached to the right vocal fold and synchronously swung inward into the trachea and outward to the larynx with inspiration and expiration, respectively. Although manual positive pressure ventilation was easily achieved without any airway obstruction after anesthetic induction, the airway was completely obstructed by the polyp lodged between the vocal cords immediately after LMA insertion. Soon after removal of the LMA, patency of the airway was dramatically improved. Conclusion: Our experience indicates that we should pay attention to airway obstruction due to lodging of the polyp between the vocal cords after LMA insertion in patients with a laryngeal polyp.ArticleJA CLINICAL REPORTS.4:43(2018)journal articl
Plasma ropivacaine concentration after TAP block in a patient with cardiac and renal failure
No full textWe report a successful ultrasound-guided transversus abdominis plane (TAP) block as an analgesic option for minor abdominal surgery in a 66-year-old patient with cardiac, respiratory, and renal dysfunction caused by primary systemic amyloidosis. Bilateral TAP blocks with 120 mg (1.8 mg/kg) of ropivacaine provided sufficient intra- and postoperative analgesia for insertion of a continuous ambulatory peritoneal dialysis catheter. However, the plasma concentration of ropivacaine reached a maximum of 2.5 mu g/mL at 15 minutes after the TAP block, a concentration that was potentially neurotoxic. Although apparent signs of local anesthetic systemic toxicity (LAST) such as convulsion or changes in an electrocardiogram were not observed, the patient became drowsy after the TAP block, which might be one of the mild symptoms of LAST. A TAP block by itself can thus be an anesthetic option for patients undergoing minor abdominal surgery. However, cardiac and renal dysfunction might influence the pharmacokinetics of a local anesthetic used, and attention should he paid to the possibility of LAST even with a low dose of a local anesthetic for patients with cardiac and renal failure.ArticleLOCAL AND REGIONAL ANESTHESIA.11:57-60(2018)journal articl
La5Ti2Cu1-xAgxS5O7 photocathodes operating at positive potentials during photoelectrochemical hydrogen evolution under irradiation of up to 710 nm
No full textA photoelectrochemical (PEC) cell based on a series-connected photocathode and photoanode made of particulate semiconductors is a potentially scalable and inexpensive device for renewable solar hydrogen production via PEC water splitting without any external power supply. The realisation of such PEC devices hinges on the development of photoelectrodes that operate at a small applied voltage. In this study, solid solutions of La5Ti2CuS5O7 (LTC) and La5Ti2AgS5O7 (LTA) were synthesised, and their physical, optical, and PEC properties in the water splitting reaction were discussed. LTC and LTA formed a La5Ti2Cu1-xAgxS5O7 solid solution (LTC(1-x)A(x)) over the whole compositional range. The indirect bandgap energy of LTC(1-x)A(x) changed nonlinearly with respect to composition, attaining its minimum value (ca. 1.8 eV) at a composition of x approximate to 0.16. Photoelectrodes of Al-doped LTC(1-x)A(x) solid solution powder fabricated using the particle transfer method exhibited a photocathodic response regardless of the Ag content. 1% Al-LTC(0.9)A(0.1) photocathodes exhibited the best PEC properties in the hydrogen evolution reaction and yielded a hypothetical half-cell solar-to-hydrogen energy conversion efficiency of 0.25% at +0.6 V vs. RHE, three times higher than the previously reported 1% Sc-LTC. In addition, 1% Al-LTC(0.9)A(0.1) photocathodes were fairly stable at + 0.7 V vs. RHE without any protective modifications. Owing to the positive operational electrode potential of 1% Al-LTC(0.9)A(0.1), unassisted PEC water splitting was accomplished using series-connected photoelectrodes made of 1% Al-LTC(0.9)A(0.1) and BaTaO2N, particulate semiconductors with absorption edge wavelengths of 710 and 660 nm, respectively, at a Faradaic efficiency of unity and a solar-to-hydrogen energy conversion efficiency of approximately 0.1%.ArticleEnergy & Environmental Science.8(11):3354-3362(2015)journal articl
Electron Microscopy Observation of Human Pulmonary Ultrastructure in Two Patients with High-Altitude Pulmonary Edema
No full textWe examined the pulmonary ultrastructure in tissue from two patients with high-altitude pulmonary edema (HAPE) by electron microscopy. In one case, we found that neutrophils were trapped in pulmonary capillary lumen of alveolar-capillary wall and part of the cytoplasm of a neutrophil protruded and adhered to the capillary endothelium. There were several degranulated vacuoles in the cytoplasm of the neutrophil. The pulmonary capillary wall was deformed, thickened, and swollen and there was evidence of degeneration. In another case, infiltration of neutrophils and macrophages, proliferation of type II pneumocytes, and numerous red blood cells were also observed in alveolar air space. These electron microscopic ultrastructural observations illustrate for the first time damage to the pulmonary alveolar-capillary barrier in lung tissue of humans with advanced HAPE.ArticleHIGH ALTITUDE MEDICINE & BIOLOGY.18(3):288-291(2017)journal articl
Radical polymerization of 'dehydroaspirin' with the formation of a hemiacetal ester skeleton: a hint for recyclable vinyl polymers
No full textA vinyl polymer with a cyclic hemiacetal ester skeleton was synthesized via the radical polymerization of 2-methylene-4H-benzo [d][1,3] dioxin-4-one (MBDO; so-called ` dehydroaspirin'). This material could be decomposed to acetic acid and salicylic acid (the raw ingredients for MBDO) by acid hydrolysis, and thus has potential as a recyclable vinyl polymer.ArticlePOLYMER CHEMISTRY.10(22):2764-2768(2019)journal articl
Ultra-SAXS observation of fibril-sized structure formation after the necking of poly(ethylene terephthalate) and poly(phenylene sulfide) fibers
No full textFibril-sized structures, which exhibit a density fluctuation of several tens to hundreds of nanometers, are important because they influence many properties of fibers and films, particularly the strength and thermal shrinkage of synthetic fibers. We analyzed the formation of fibril-sized structures after necking using ultra-small-angle X-ray scattering (USAXS), which enables observation of the void and craze formations. Continuous laser-heated drawing and undulator synchrotron radiation were adopted to measure the structural development of poly(ethylene terephthalate) (PET) and poly(phenylene sulfide) (PPS) fibers. Both fibers showed a clear increase in the meridional streak intensity just after necking and an increase in the equatorial streak after necking. These increases were distinctive for PPS. Moreover, a layer-lined streak appeared after necking only for PET. The intensity of the meridional streak increased with an increase in the draw ratio, whereas the intensity of the layer-lined scattering decreased with an increase in the draw ratio.ArticlePOLYMER JOURNAL.51(2):211-219(2018)journal articl
The Batalin-Vilkovisky Algebra in the String Topology of Classifying Spaces
No full textFor almost any compact connected Lie group C and any field F-p, we compute the Batalin-Vilkovisky algebra H*(+dim G) (LBG; F-p) on the loop cohomology of the classifying space introduced by Chataur and the second author. In particular, if p is odd or p = 0, this Batalin-Vilkovisky algebra is isomorphic to the Hochschild cohomology HH* (H-*(G), H-* (G)). Over F-2, such an isomorphism of Batalin-Vilkovisky algebras does not hold when G = SO(3) or G = G(2). Our elaborate considerations on the signs in string topology of the classifying spaces give rise to a general theorem on graded homological conformal field theory.ArticleCANADIAN JOURNAL OF MATHEMATICS-JOURNAL CANADIEN DE MATHEMATIQUES.71(4):843-889(2019)journal articl
