ネットワーク信頼性評価とは,ネットワークの各リンクに静的な故障確率が設定されている場合に,2 頂点間が通信可能である確率を求める問題である.確率を厳密に計算する手法として,二分決定グラフ (BDD) を用いた計算方法が知られている.BDDは 論理関数を圧縮して効率よく表現できるデータ構造である.本稿では,ネットワークの 2 つ以上のリンクの故障に依存関係がある場合の信頼性評価を行う.本手法では,リンク間に存在する依存関係を BDD で表現し,依存関係を考慮しない場合に構築した BDD との二項演算を行うことで,依存関係を考慮した信頼性 BDD を生成し,確率を計算する.本手法を 3 つの計算方法で実装し,各方法を処理時間と生成される BDD のノード数の観点から比較を行う.

Positive emotional activities such as mirthful laughter have recently been suggested as modifiers of neuroendocrine hormones involved in the classical stress response. In other words, spontaneous laughter is suggested to contribute to physiological and psychological health. \nFor example, Berk et al. (1989a,b) reported the relationship between natural killer cell activity and laughter. They also reported that the mirthful laughter experience appears to reduce serum levels of cortisol, dopac, epinephrine, and growth hormone. These biochemical changes have implications for the reversal of the neuroendocrine and classical stress hormone response. \nThis study investigated the effects of spontaneous laughter on autonomic nervous response to a humorous video. Thirty students were classified randomly divided into a laughing group who watched the DVD and laughed spontaneously(n = 15) or a control group who watched the blue screen of a monitor(n = 15).During all experimental sessions, electrodermal activity(EDA), heart rate(HR), and skin temperature(ST) were measured. \nResults revealed no changes in the autonomic nervous responses in the control group. In the laughing group, however, sympathetic reactivity accelerated significantly in the experimental session and then decreased significantly in the recovery session. Thus, spontaneous laughter indicated the effects of relaxation. \nResults of the Profile of Mood States(POMS) revealed no changes in emotions in the control group after the experimental session but did reveal a decrease in negative emotions and increase in positive emotion were recognized in the laughing group.\nDetailed studies of other autonomic nervous responses, and baroreflex sensitivity in particular, must be conducted in the future.

Based on Japanese krill fishing and minke whaling data, the distribution of Antarctic krill (Euphausia superbd) concentrations was investigated in relation to bottom topography, sea-ice and hydrographic features. Data were from the Indian, Pacific and western Atlantic sectors. In early summer (December) high density concentrations of krill frequently occurred in the vicinity of southerly positioned pack-ice edges and in the embayments surrounded by the pack-ice edge. In mid and late summer (January-March) when the ice-edge was at its southern-most limit, krill fishing data indicated that harvestable areas were associated with the continental and insular shelf breaks, not with the pack-ice edge. Minke whaling data also suggested that not only sea-ice but also topographical features such as the continental shelf breaks and banks may be important factors affecting minke whale (Balaenoptera acutorostratci) distribution. Krill harvesting areas in the vicinity of the shelf breaks were often coincident with hydrographic fronts. These results suggested that hydrographic features caused by uneven bottom topography (e. g. shelf breaks or banks) may induce the formation of krill concentrations in mid and late summer. The extremely high concentration of minke whales and their food composition suggested the high abundance of E. superba around a bank on the Ross Sea shelf.

本稿の目的は、政策学の思考方法について検討し、公共政策の文脈的理解を強調することである。政策学の方法に関する三つの主張、つまり帰納的推論の思考は仮説設定、課題設定に貢献でき、行政学は制度や管理の文脈で政策について研究可能であり、政策学の学問的基盤は包括理論でなくてもよい、という主張を行う。さらに、トリアージ、特定商取引法改正、薬のインターネット販売の三つの政策事例を取り上げ、二つの価値の二律背反構造を条件づける文脈について比較検討し、決定の文脈的理解をより深めるために条件づけを明示化する必要があることを示す。

In Japan, wa (和. he in Chinese) is still popular as an important tenet taught by Prince Shotoku in the Ancient Age. In this paper, the author tries to analyze the concept of he as it appears in Chinese and Japanese Buddhist texts (Especially Chinese Versions of the Buddhist Canons) and clarify its various meanings, some of which have been deeply influenced by Chinese thought. Since the time of Early Buddhism, Buddhists have fundamentally attached importance to unification and harmonious relations of the order. For example, the famous Dhammapada says, sukha sanghassa samaggi samagganam tapo sukho. Samaggi in this sentence was translated he (和) or hehe (和合) in China. This seems to be the most basic sense of he in Buddhism. Secondly, the idea of hejing (和敬), which relates with he mentioned above is also notable. This idea served as the base of the theory of six kinds of hejing (六和敬), which means harmonious behaviors in the six fields of body (身), speaking (口), mind (意), sila (戒), view (見), and benefit (利) in general. But it does not seem that this theory was formed before the occurrence of Mahayana Buddhism in the first century B.C. and widely prevailed all over the Buddhist world. Thirdly, there is the term of heyan-aiyu (和顔愛語. wagen-aigo in Japanese). This phrase is very popular in Japan. However, we can not find out any equivalent in the Sanskrit text of the Amitayus-sutra to heyan, that constitutes the most well-known idiom in one of the Chinese versions of it. Fourthly, we discuss the concept of heguang-tongchen (和光同塵) 50 Buddhism and the Concept of he (和, wa in Japanese) in East Asia (Kimura) originating in the Laozi. This was accepted in Chinese Buddhism in two ways, i.e., one positive, and the other negative. We can see one typical example of the positive usage of this idiom in the Great Concentration and Insight (Mohezhiguan.摩訶止観) by Zhiyi (538-597). The negative usage of it, in the expression butongqichen (不同其塵) appears in the Mahayana-nirvana-sutra translated by Dharmaksema. Lastly, the author investigates the relationship between these various meanings of he in East Asian Buddhism and the thought of he advocated by Prince Shotoku. Our conclusion is that Prince Shotoku tried to apply the Buddhist idea of samaggi to the secular society at large.

Spiruchostatin A (1), isolated from a culture broth of Pseudomonas sp., has been shown to be a potent histone deacetylase (HDAC) inhibitor. HDAC inhibitors can suppress the growth of human tumor xenografts, this natural product, therefore, is expected to be a promising candidate for novel molecular-targeted anticancer agents. We envisioned that 1 would be synthesized through twofold macrolactam/macrolactone cyclization of the fully elaborated acyclic disulfide 2. The key segments 3 and 4, required for the preparation of the advanced key intermediate 2, were initially synthesized, and the two segments were subsequently subjected to the critical cross S-S coupling reaction to produce the desired key intermediate 11 (synthetically equivalent to 2). Upon deprotection of the N-Boc and the methyl ester groups in 11, the crucial cyclization formation was achieved using PyBOP to provide the desired macrolactam 16, a potential key precursor for 1. Further investigations concerning the transformation of 16 to the target molecule 1 were also described.

テーマ辞典をもとにフレーズ開始の音程がアナクルーシスを形成するものを選び出し、これを音程、音長別にわけて分析した。その結果、音程で上行4度と1度、音長で1:2と1:1が双璧をなすアナクルーシスであることが明らかになった。(両者の組み合わせから実際には4つの典型的パターンが抽出される。)これを基に、典型的アフタクトの音程2種類と、そうでない音程1種類、これに典型的な音長2種類とそうでない音長1種類の3種類を組み合わせることによって合計9つのパターンを作り出した。これらのアナクルーシスは、そうでないパターンと演奏上どう区別されるだろうか。パターンの違いによる違いはどうか。さらに、音長間係の楽譜からの逸脱を示す一般的な演奏傾向との関係はどうか。本研究は、以上の一連の研究の途中報告である。
