7月23日(土曜日)午後4時35分。関東地方を襲った震度5強の地震は鉄道網をマヒさせ、東日本旅客鉄道(JR東日本)だけで44万人の足に影響を与えた。同社(総合ランキング51位)では運転再開までに最長約7時間、地下鉄の東京メトロでも同じく4時間近くを要した。一方、建物や道路などの損壊がほとんどなかっただけに、遅れに対する批判が噴出。

This paper attempts to introduce briefly the activities of a certain school of pencak silat, a kind of martial arts practiced all over Indonesia. Adding to this aim, the author attempts to examine whether or not the argument of "craft language" discussed by students of Japanese traditional performing arts could be able to be applied for this martial art from Indonesia. In the practice of pencak silat, coaches use some kinds of unique expressions using language mainly during the practice of breathing techniques. These expressions, however, are different from "craft language" in the strict sense. This is because coaches use these expressions for the purpose of students' meeting their own "correctness".

懸濁気泡塔における気-液接触反応の物質移動抵抗を評価する目的で,パラジウムーアルミナ触媒によるα-メチルスチレンの液相水素化反応を行なった。<BR>物質移動抵抗のうち,気-液間抵抗(1/kLah)は単独に評価できるが,液-固間抵抗(1/ksaa)は反応抵抗を含む総括抵抗から分離しなければならない。水素の触媒表面濃度が化学反応速度と総括速度の比によって,ま塵反応抵抗と総括抵抗の比によって,ともに水素の気-液界面濃度に関係づけられるので,1/kLabの値と,通気ガキマゼ糟を用いて反応過程律速のもとであらかじめ求めた表面反応速度の値を用いて1/ksaa,を単離して評価できる。<BR>このようにして,両抵抗を別個に評価し,それぞれ懸濁気泡塔の操作変数(通気速度および触媒濃度)との関係を定量的に示した。また総括抵抗に寄与する各抵抗の割合と操作変数とめ相関性を求あた。ざずらに,ガスホホールドアップ,気泡径,気-液界面積および物質移動係数などと操作変数との関係を検討しほぼ妥当な結果を得た。

We compared the diagnostic reliability of 3.0-T magnetic resonance imaging (MRI) for detection of osseous abnormalities of the temporomandibular joint (TMJ) with that of the gold standard, cone-beam computed tomography (CBCT). Fifty-six TMJs were imaged with CBCT and MRI, and images of condyles and fossae were independently assessed for the presence of osseous abnormalities. The accuracy, sensitivity, and specificity of 3.0-T MRI were 0.88, 1.0, and 0.73, respectively, in condyle evaluation and 0.91, 0.75, and 0.95 in fossa evaluation. The McNemar test showed no significant difference (P > 0.05) between MRI and CBCT in the evaluation of osseous abnormalities in condyles and fossae. The present results indicate that 3.0-T MRI is equal to CBCT in the diagnostic evaluation of osseous abnormalities of the mandibular condyle.

Accurate impressions are essential in fabri-cating dental restorations and fixed dental prostheses. During the last decade, digital impression systems have improved substantially. This review discusses the accuracy of digital impression systems for fabrication of dental restorations and fixed dental prostheses. A literature search in PubMed was performed for the period from July 2010 through June 2017. The search keywords were Cerec, digital impression, direct digitalization, indirect digitalization, and intraoral scanner. Only relevant studies are summarized and discussed in this review. In general, the latest systems have considerably reduced the time required for impression making, and the accuracy and marginal fit of digital impression systems have recently improved. Restorations and fixed dental prostheses fabricated with currently available digital impression systems and intraoral scanners exhibit clinically acceptable ranges of marginal gap in both direct and indirect procedures.

日常生活環境の中に存在している様々な環境音を組み合わせて創った音楽がある。<br />この音楽は、楽器音ではなく環境音を用いることで、音楽に付加価値を与えることができる。<br />しかし、多くの環境音は音楽を生成するのに必要な音高が認知しにくく、<br />そのような環境音のみで音楽を生成すると、音楽として認知しにくくなってしまう。<br />また、音高を認知しやすい音ばかりを用いてしまうと、付加価値が減少してしまう。<br />そこで、音高が認知しにくい環境音を用いてもどの程度なら音楽として認知しやすいかを検討した。<br />まずは、環境音を組み合わせて創られた音楽の例であるHondaのCM「Music」篇に着目し、検討した結果を報告する。

The effect of grinding in an agate centrifugal ball mill at 200 rpm on the physicochemical properties of indomethacin (IMC) polymorphs was studied by means of X-ray diffraction analysis, infrared spectroscopy and differential scanning calorimetry. The α and γ forms (metastable and stable forms) of IMC were ground at 4°C ant at 30±0.5°C, and the degree of crystallinity (Xc) of the ground products was measured by the X-ray diffractional internal standard method.The Xc of the γ form ground at 4°C decreased with increasing grinding time, and was 0% after 4 h, that is, the γ form had been converted to a noncrystalline solid. After grinding for 1 h at 30°C, about 45% of γ form of IMC was converted to noncrystalline solid, while the product ground for 10 h was transformed to the α form.The Xc of the α form ground for 2 h at 4°C was 0%, that is, the αform had been converted to a noncrystalline solid within 2 h at 4°C. The Xc of the α form ground at 30°C decreased with increasing grinding time and the value after 10 h was about 60%.The solubility in distilled water at 35°C of the γ form ground for 10 h at 4°C was about 60% larger than that of the intact γ form. The solubilities of the γ form gournd for 10 h at 30°C, the α form gound for 10 h at 4°C and the α form gound for 10 h at 30°C were all the same, 0.94 mg/100 ml, which is equal to that of the α form at 35°C.

The effects of grinding on the physicochemical properties of cephalexin (CEX) were studied by means of water content measurements, differential thermal analysis (DTA), differential scanning calorimetry (DSC), X-ray diffraction analysis and scanning electron microscopy (SEM). The water content of CEX which had been ground for 4h and converted to a noncrystalline state was proportional to relative humidity (RH) in the range of 0-62% RH, and was about 2 mol/mol at 62-82% RH. The water content of intact crystal phase IV was about 1 mol/mol at 20-75% RH, and about 2 mol/mol at 82-95% RH. The X-ray diffraction data indicated that ground CEX remains in the noncrystalline state until it has absorbed more than about 2 mol of water per mol. At 62% RH, the water content of phase IV increased with increasing grinding time due to the conversion to noncrystalline state. The dehydration point of the ground CEX was depressed by up to about 25°C with increasing grinding time, and the decomposition point of the ground products was depressed by up to about 30°C. In general, the physicochemical properties changed rapidly when the crystallinity of the ground product fell below about 25%. The activation energy and mechanism of dehydration were determined by using nonisothermal kinetic analysis (Criado's method). The dehydration of the product ground for 4h (noncrystalline solid) followed first-order kinetics and its activation energy and latent heat were calculated to be 14.83 kcal/mol and 8.31 kcal/mol, respectively. The product ground for 4h was about 2.5 times more soluble than intact phase IV. The dehydration behavior and solubility of the product ground for 4h were different from those of the freeze-dried product, even though both products are in a noncrystalline state.

The effect of grinding in an agate centrifugal ball mill on the transformations of polymorphs of chloramphenicol palmitate (CPP) were studied by means of X-ray diffraction analysis, infrared (IR) spectroscopy and differential scanning calorimetry (DSC). Three kinds of the polymorphs of CPP were reported, that is, forms A, B and C. There was no change in the X-ray diffraction profile of form A (stable form) on grinding for 600 min, but its profile became broader than that of intact form A. There was no change in the X-ray diffraction profile of form B (meta-stable form) on grinding for 130 min, but form B was transformed into form A by grinding for more than 140 min. Form B ground for 140 min contained about 35% form A ; when ground for 150 min, it contained about 80% form A, and when ground for more than 150 min, it contained a constant level of about 80% form A. The X-ray diffraction profile of form C (meta-stable form) suggested that form C was transformed into form B by grinding for 20 min ; thereafter the product was transformed into form A by grinding for 160 min. Form C ground for 4 min contained about 60% form B ; when ground for 20 min, it contained about 100% form B, and ground for 160 min, it contained about 80% form A. These results suggest that the transformations of polymorphs of CPP by grinding are form C→form B→form A. The melting point (mp) and the heat of fusion (H) were measured by DSC. The mp and the H of form A obtained by grinding were about 2.5°C and about 2.5 kcal/mol lower than those of intact form A, respectively, and the solubility in 50% (v/v) aqueous isopropyl alchohol was about twice that of intact form A.
