喘息発作の出現と亜熱帯地域に位置する沖縄県地方の気象因子との関連を追求した.気管支喘息患者27例を対象とし過去2年間を, 喘息日記を用いて調査した.喘息発作の程度は, 喘息日記の記載から発作点数合計として算出した.一方, 喘息発作患者の救急車搬送頻度は, 那覇市消防局による過去3年間の調査結果を基にした.沖縄県那覇市の各気象因子が調査期間の平均値より高いか否かと, 喘息発作の発生との因果関係を, 2×2分割表にて分析した.その結果, 喘息日記の調査からは, 平均気温ならびに最低気温がそれぞれ調査期間の平均値を上回る日に喘息発作点数合計の上昇が認められた(p<0.05).一方, 救急車搬送頻度の調査からは, 平均気温および最高気温, 最低気温が調査期間の平均値を下回る日(p=0.0001, p=0.0001, p<0.0001), 平均蒸気圧が平均値を下回る日(p=0.0002), 平均海面気圧が平均値を上回る日(p=0.0016)に喘息発作が起こりやすいと推察された.さらに, 重回帰分析により, 低温の救急車搬送頻度に及ぼす影響の大きいことが示唆された.また, 台風接近にともなう気象因子の急変, 特に, 気温や気圧の急激な低下は喘息発作の誘因になる可能性が示唆された.

Prostanoic acid (18) and 8-isoprostanoic acid (1) constitute the basic structures of primary prostaglandins and 8-isoprostaglandins. The conversion of commercially available (+)- and (-)-limonene to these compounds was accomplilshed by a sequence of reactions involving the Rh(I)-catalyzed cyclization of 3, 4-disubstituted 4-pentenals, which were easily prepared from (+)- or (-)-limonene, to cis-3, 4-disubstituted cyclopentanones and the appropriate modification of substituents on the five-membered ring.

There are many studies reported that a fatigue crack propagated in a tensile mode macroscopically and the fracture surface was mainly occupied by striations in many metals. Whereas, a unique fracture in which a crack propagated in a macroscopic shear direction accompanied by ductile facets was observed in some aluminum alloys under specific conditions. In the present study, fatigue tests of age-hardened Al alloys of extruded 2017-T4 and 7075-T6 were conducted in relative humidity environments of 25% and 85% under rotating bending and ultrasonic loading conditions to clarify the crystallographic feature of a shear mode crack and propose its growth mechanism. Many facets showing a feature of shear mode crack propagation with an equivalent size to the grain size were observed at the fracture surface under both conditions of rotating bending in high humidity and ultrasonic loading irrespective of humidity. In addition, it was confirmed that the angle between the loading axis and the growth direction of the shear mode crack composed a constant value, ~35°, relating to the marked texture in the propagation process of the macroscopic shear mode crack. However, a crack growth rate was lower in the ultrasonic loading than in the rotating bending in high humidity. Based on their differences in occurrence conditions of the shear mode crack, two mechanisms for this unique propagation were proposed as follows; that is, one was a shear mode crack occurred by the promotion of the slip deformation to one direction due to hydrogen generated by reaction of Al alloy with water vapor in high humidity, and the other was a crack by the suppression of the deformation to one direction due to re-welding of crack faces under ultrasonic loading.

本研究は、奈良県・吉野を事例に、国史、山岳信仰、桜の鑑賞、林業など地域の多様で複雑な背景に対する世界遺産登録の評価を分析し、国際的な評価と地域の実態との乖離を検証することを試みた。地形図やGISに基づく景観の成立過程の把握、および世界遺産登録に関係する国内外の公式資料の調査を行った。吉野の森林は林業によって形成され、修験道の山岳修行の道である大峯奥駈道周辺は、戦後の森林施業で人工のスギ林に囲まれた空間へと変化してきた。しかし、世界遺産登録において、UNESCOやICOMOSでは吉野の森林が高く評価され、その神聖性が強調されていた。地域の多様な背景のうち一部が注目され、かつ、人の営みで成立してきたという実態とは異なる理解がなされていたことが明らかとなった。Seeking to protect international and universal values, the World Heritage highlights specific aspect of diverse and complicated backgrounds of a local place. Assessing what aspect was valued and what was not at the World Heritage inscription is important in understanding a local place as a whole. Yoshino as part of the World Heritage site "The Sacred Sites and Pilgrimage Routes of the Kii Mountain Range" involves associations with national history, a history of mountain ascetic belief, an appreciation as a scenic cherry blossom site, and traditional forestry activities unique in this region. This research analyses evaluations on the diverse backgrounds of Yoshino made at the World Heritage inscription, to figure out the discrepancy between the international and the local. It utilized topographical maps and GIS data to identify spatial transitions of a landscape of Yoshino. It then reviewed documents related to the World Heritage inscription from UNESCO, ICOMOS and the Japanese Government to see which aspect was highly valued. Spatial analysis discovered that a landscape around O-mine Oku-gake Michi, a training path across mountains for the ascetic religion, has changed over the 20t h century. Views from the path previously included a wide view to distant mountains but due to development of forestry activities, now they are entirely enclosed surrounded by planted cedar forests. On the other hand, evaluations by UNESCO and ICOMOS featured the ascetic belief and particularly emphasized sacredness of forests. While not recognizing the fact that the forest in Yoshino is mostly an artificial plantation developed over time due to the human intervention, the World Heritage inscription associated the forests with religious ascetic practices. This revealed a discrepancy between an international understanding on a local area and the local reality, which the international focused on one specific aspect of local diversities and failed to grasp exact background of the highlighted aspect.
