The Edifice of Hiuchi Volcano was founded on the Mokake ignimbrite plateau which is directly underlain by the Nanairi pumice. They erupted from near the present summit successively about 350ka. On the plateau, the Ozorizawa cone was first established about 100 ka. Next, the Shibayasugura cone having twin peaks, Shibayasugura (2, 356 m) and Manaitagura (2, 346 m), was built shifting slightly southeast. At 19ka, the Jubeike lava flow and Kumazawa Tashiro lava dome were issued from the northeastern flanks. The latter was accompanied by a devastating blast. Southward-opening horseshoe depression is source of the Nushiri debris avalanche, which dammed up the Nushiri River and formed the Oze marsh about 8ka. The Akanagure lava dome and flows immediately occupied the depression. The youngest volcanic feature at Hiuchi is the Miike lava dome, 300m south of the Manaitagura peak. It emplaced during the 16th century, just before the Shirohikemizu flood descended the Hinoemata River on July 28, 1544. Hiuchi Volcano has erupted 17 × 1012 kg of magma since its birth, 350 thousand years ago. Average discharge rate is 4.9 × 1010 kg per thousand years, an order of magnitude smaller than that of the most active Japanese volcanoes.

In spite of the steady progress of thechnology in the glass industry, there still remain many problems. Contributions of mineralogy to the glass industry include a characterization of material minerals and a study of stones grown in the course of glass production. The further contributions are expected to the present problems in the glass industry; for example, prospect of the material supply, origin of stones, development of new devitroceramics and structure of new kinds of glass

A 45-year-old Japanese man with paroxysmal atrial fibrillation (AF) developed acute anteroseptal myocardial infarction (MI). He had used 1 % topical minoxidil (RiUP®) once a day for 4 months before the onset of MI for treatment of baldness. Coronary angiography demonstrated severe stenosis at the proximal portion of the left anterior descending coronary artery with a filling defect. Electrocardiographic monitoring revealed paroxysmal AF and sinus bradycardia with sinus arrests, suggestive of sick sinus syndrome. Topical minoxidil is now widely used for the treatment of male pattern baldness. Although it may be difficult to relate topical use of minoxidil to myocardial ischemia, a greater awareness of its toxicity will be necessary, and patients with cardiovascular disorders should be excluded from the therapy.

Two types of ambiguity are recognizable in Dempster and Shafer's theory of evidence. One is the ambiguity of the system itself and the other is the ambiguity of human knowledge or information about the system. In this paper, from this point of view, the property for measuring the ambiguity of the system and the property for measuring the ambiguity of human knowledge or information are discussed. A global measure of information which satisfies both of these properties is proposed. The unicity of the, proposed measure is proved when it must be an extension of Shannon entropy. The soundness of this measure of information is confirmed by a simple experiment.

The osmotic pressure generation was firstly presented as pressure-retarded osmosis (PRO) power generation by S. Loeb in 1976. The possibility and problems of the production of hydroelectric power by osmotic pressure generation have been discussed by S. Loeb, Takeo Honda, Fukuoka Water Service Consortium and SINTEF. They, however, have not been realized because of the problems in membranes though the power production cost is was low. In this paper those problems in the membrane are introduced and the way how to solve them is discussed.

Salinity gradient power (SGP) is one of a renewable energy that is available when two solutions of different salinity mix. The global potential for SGP is calculated to be 2.6 TW when the flow of all rivers is taken into account. There are two membrane-based technologies that can change SGP into useful electricity ; reverse electrodialysis (RED) and pressure retarded osmosis (PRO). It has been shown that, in the case of river water with seawater, RED is a promising technology. The key components in a RED system are ion-exchange membranes (IEMs). Membrane requirements for RED are high perm-selectivity, low electrical resistance, safficent mechanical stability, high chemical stability, high anti-fouling properties and low cost. Here, the principle and technological trend of the system and IEMs for RED is presented.

本研究は,合理的処理および直観的処理における個人差(Pacini & Epstein, 1999)を測定する情報処理スタイル尺度(IPSI)の作成を目的とした.調査1(回答者290名)ではIPSI38項目の内容的妥当性を検討するため,確認的因子分析を行った.分析の結果,IPSIが合理性と直観性の2因子から構成されることが確認された.また,IPSIは十分な内的一貫性および再テスト信頼性を持つことが示された.他の尺度(曖昧さへの耐性と理論志向性,自尊心,社会的望ましさ)との相関はIPSIの収束的・弁別的妥当性を示すものであった.調査2(回答者237名)では,構成概念妥当性の検討のため,確率推論課題の回答とIPSIの関連を調べた.その結果,直観性および合理性が推論エラーの頻度と関連することが示された.加えて,調査2ではIPSI短縮版24項目を作成し,その信頼性と妥当性が確認された.
