Noninvasive risk stratification is important for screening for lethal arrhythmia. We developed a 187-channel signal-averaged vector-projected high-resolution electrocardiograph (187-ch SAVP-ECG) for detecting abnormalities in the spatial location of ventricular high-frequency late potentials (HFLPs) and ventricular repolarization. The subjects consisted of 30 normal controls (CONTROL) and 13 patients with HFLPs (6 with myocardial infarction [MI], 6 with cardiomyopathy, and 1 with Brugada syndrome). The modified X, Y, Z-lead ECG and the synthesized signals from vector-projected 187-channel ECGs were amplified and passed through a digital filter. We calculated the integration of the HFLPs area between QRSend and 30 ms before QRSend. The integrated HFLPs map was superimposed on the corrected recovery time (RTc) and Tpeak-end dispersion maps composed by 187-ch SAVP-ECG. All patients received an examination by 64-channel magnetocardiography (64-ch MCG) on the same day. The spatial distribution of HFLPs by the 187-ch SAVP-ECG map was in agreement with the location of increased RT dispersion in MI. The spatial distribution of HFLPs in DCM demonstrated a wide variety of patterns. Interestingly, the spatial distribution of HFLPs in cases with ARVC was located at around a right ventricular outflow region. The spatial distribution of HFLPs by 187-ch SAVP-ECG was in agreement with those determined by 64-ch MCG. The 187-ch SAVP-ECG might be useful for evaluating the spatial distribution of nonuniform conduction and ventricular repolarization heterogeneity.

The tyrosinase inhibitory activity of the extracts of 53 parts of 36 plant species cultivated for edible and medicinal use in Okinawa was investigated. The extract of Nandina domestica showed potent activity among these. The inhibitor in the extract was purified by assay-guided fractionation to give a simple phenol glucoside. Although it was a known compound (4-β-D-glucopyranosyloxybenzoic acid), its inhibitory activity toward tyrosinase is revealed for the first time in this work.

多くのリハビリ患者に強く推奨されている起立-着席訓練に,エンタテインメント性を付加し患者・利用者の積極性,持続性を向上させるべくゲーム制作を行った.訓練内容の選出をはじめ,設置環境,対象とする患者・利用者の身体能力等について,リハビリスタッフと協議し決定している.視覚,聴覚,インタラクション等,ゲームデザインに必要な要素についても同様に協議を重ね,現場での試用によるフィードバックを得ながら制作している.プロトタイプ完成後,48名の被験者により有効性と安全性を検証する評価実験を行った.実験は起立-着席訓練を1人で行う場合,ゲーム利用時,リハビリスタッフ介入の3条件下の比較により行われ,ゲームはリハビリスタッフとほぼ同様の役割を果たす,有効なものであるという結果を得ることができた.In this study, we developed a game adding entertainment elements to help stand-up rehabilitation exercise which is strongly recommended to patients by reason of raising their motivations and persistences during the exercise. We carefuly discussed with rehabilitation staff and selected a kind of exercise, where to install and the suitable physical ability of the patients for the experiment of the game. And we also adopted the elements necessary for the game design such as audio, visual and interactions into the game getting feedbacks from the rehabilitation staff and the patients. The empirical studies involving 48 subjects were carried out after testing the prototype to confirm it to be useable and safe. It was done by a comparative method under 3 conditions of stand-up exercise; self exercise, exercise with the game and exercise with a rehabilitation staff. The results showed that it was a useful, fun, and safe game that fulfilled nearly every role that a rehabilitation staff would perform in an equivalent manner.

This paper discusses mainly the lexical items which suspend conversational implicature, such as if any, if anything, if ever and if not, and secondarily the one which blocks the emergence of conversational implicature like not...until. If any, etc. are representative of suspension of conversational implicature in a general sense, but this is in fact not the case, as is illustrated by the doubt whether the suspended meaning is really conversational in the Gricean sense. According to Horn (1972) and many others, a lower item on a semantic and pragmatic scale allows for the possibility of something stronger holding. This possibility, however, is allowable only when the suspension words are added to the quantified predicates. It is not until if any, etc. are uttered that suspension is implicated, whether conversationally or not. Second and last, not...until sometimes allows and sometimes blocks the occurrence of conversational implicature, i. e., the sense of actualization (Declerck's terminology). The sense of actualization is implied strongly at some time and weakly at another time. The degree of the implied actualization is determined by the hearer's corollary, which is not explainable only by the Gricean and neo-Gricean Quanity Maxims.

We had previously shown that performing a single set of resistance exercise at 50% of 1 repetition maximum (RM) added after a high-intensity, low-repetition exercise (strength-type regimen) greatly enhanced growth hormone (GH) secretion [Goto et al. (2003)]. The present study aimed to investigate the effect of an additional set at 50% to 20% of 1RM after a strength-type regimen on anabolic hormone secretion. Eight male subjects performed bilateral knee extension exercises using a strength-type regimen (5 sets at 90% of 1RM, with 3-min rests), and other 3 types of regimens, in which 1 set of exercise at either 50%, 30% or 20% of 1RM was added immediately after the strength-type regimen (defined as C50-type, C30-type and C20-type regimens, respectively). Concentrations of serum GH, testosterone and blood lactate were measured before and after exercises. The number of repetitions in the added set showed a significant dependence on the exercise intensity: 82.3 times in C20-type > 46.1 times in C30-type > 22.6 times in C50-type (p ≤ 0.05). Post-exercise GH concentrations were significantly (p ≤ 0.05) higher in C50- and C30-type regimens than in the strength-type regimen, whereas no significant difference was observed between C20- and strength-type regimens. Testosterone did not change in any types of regimen. These results indicated that performing a single set of exercise at low intensity added after a strength-type regimen caused a significant increase in GH concentration. However, such an effect might be diminished when the intensity of the additional exercise was extremely low (below 20% of 1RM).

We call a positive semidefinite matrix whose elements are nonnegative a doubly nonnegativematrix, and the set of those matrices the doubly nonnegative cone (DNN cone). The DNN coneis not symmetric but can be represented as the projection of a symmetric cone embedded in ahigher dimension. In [16], the authors demonstrated the efficiency of the DNN relaxation usingthe symmetric cone representation of the DNN cone. They showed that the DNN relaxation givessignificantly tight bounds for a class of quadratic assignment problems, but the computational timeis not affordable as long as we employ the symmetric cone representation. They then suggested aprimal barrier function approach for solving the DNN optimization problem directly, instead of usingthe symmetric cone representation. However, most of existing studies on the primal barrier functionapproach assume the availability of a feasible interior point. This fact means that those studies arenot inextricably tied to the practical usage. Motivated by these observations, we propose a primalbarrier function Phase I algorithm for solving conic optimization problems over the closed convexcone K having the following properties: (a) K is not necessarily symmetric, (b) a self-concordantfunction f is defined over intK, and (c) its dual cone K∗ is not explicit or is intractable, all of whichare observed when K is the DNN cone. We analyze the algorithm and provide a sufficient conditionfor finite termination.

フラッシュ符号の一種であるindex-less indexed flash codes (ILIFC)の改良を行う.フラッシュメモリの利用にあたっては,セルと呼ばれる記録素子に対する操作への非対称性,ブロック消去に伴うセル特性の劣化等に十分注意して,情報の記録を行う必要がある.ILIFCは,セル全体をブロックと呼ばれる小単位に分割し,各ブロックを有効に利用することで性能確保を目指す方式であるが,ブロックサイズが固定されていることから様々な問題が発生する.本研究では,ILIFCのブロックサイズを半減し,性能を改善するとともに,その適用範囲を拡大することを検討する.

新規殺虫剤ピリダリルのハスモンヨトウ幼虫に対する殺虫作用について局所施用法により調査した.処理3日後の死虫率に基づくピリダリルのLD_<50>値は24.4ngであった.400〜100ng/個体処理においては処理後6時間以内に死虫率100%に達したが,痙攣,苦悶などの症状は示さず,弛緩,麻痺するように死亡した.一方,25ng/個体以下の処理では処理2日後以降生き延びた個体において処理部が暗色に変化する症状が見られ,25ng/個体処理では処理5日後に全身が黒色になって死亡する個体が見られた.また,12.5,6.25ng/個体処理においては脱皮後,処理部に火傷状の変性が見られた.これらの幼虫の多くは以降正常な変態ができずに死亡した.このように,ピリダリルは即効的致死量未満においてもハスモンヨトウ幼虫の正常な発育を阻害し,密度抑制に貢献することが期待された.ピリダリルの生化学的作用機構の詳細は未だ不明であるがその特徴的症状から新規のものと予想された.

本研究は、これまで十分になされてこなかった日本農業の歴史と農耕文化に根ざした日本農学原論を構築するために、大正・昭和期において日本農学がどのように展開してきたかを、史料調査と農家からの聞き取り調査に基づきながら、実証的に明らかにした。欧米農学を融合しながら日本農業の伝統に根ざして作られてきた日本農学の基本的な哲学、原論的理念を明らかした。
