With the development of global linkage in economy, especially, competition in inter-market is increasing in international financial / capital sector. In such competition, one of the most common examples is dual listing of financial products and competition for its“ order-flow” between markets. In this paper, we examine the effects of the competition and mutual benefits between markets. Specially, we are interested in and make empirical analysis for the competition of financial derivative products such as stock index futures in Japan and Singapore.

This paper proposes a sustainable IP network using small-scale power generation facilities and renewable energy in off-grid areas with wireless LAN APs that consist of adaptive autonomous mobile robots. The wireless LAN access points are designed to use biodegradable materials as much as possible to minimize the impact on the natural environment, even if they break down during operation and are difficult to recover. We will also design and implement a new mesh network protocol among wireless LAN APs that is robust to changes in the natural environment.

本研究では,図画工作・美術科教育において大きな課題の一つとなっている「図画工作科の教科観(図工観)」の転換に着目した。本研究の目的は,質問紙調査への回答と記述内容の分析から,初等教科教育法(図画工作)の受講学生の「図工観」の変容について考察することである。その結果,以下のような結論を導いた。第一に,「作品中心の図工観」,「作品を作らせるための指導観」から子どもの「発想」や「造形活動の過程」を重視した「図工観・指導観」に変容した。第二に,教科の目標や評価規準についての理解を深め,「教科」としての位置付けを理解した。第三に,図画工作科を指導することへの不安は低下したが,子どもの造形の特徴や明確な指導法の理解が十分ではなく,実践的指導力への不安をもっている。学生に子どもの造形の特徴や具体的な指導法を十分に理解させるための実践が今後の課題である。

テストの自動化は,市場の変化に迅速に対応して素早くソフトウェアをリリースするために重要である.しかし,画面の操作を伴うテストスクリプトの実装および保守のコストは自動テスト導入の大きな障壁となっている.一方,画面表示やユーザビリティのテストなど,現在の産業界におけるテストは人手に頼る部分も多く存在している.本研究では,このような人手によるテストのログを用いて,ページオブジェクトパターンを採用した有用なテストスクリプトを自動生成する手法を提案する.提案手法を利用することで,ソフトウェア開発で必要不可欠な手作業によるテストを行うだけで有用なテストスクリプトを生成することができ,テストスクリプトの実装・保守のコストを下げることが期待できる.

This article examines the characteristic features of the Jinwuwei 金吾衞 Regiment, one of the Twelve Imperial Guards (Shi’erwei 十二衞) units in China’s Southern Command (Nanya 南衙) system from the viewpoint of its relationship to the military command authority of the Tang Period Emperors. The author’s findings are as follows. First, the Jinwuwei was integrated into the emperor’s military command and was the Imperial Guard unit that functioned to activate that authority. This special character of the Jinwuwei stems from the “yuhou” 虞候 military system of the Northern Dynasties and the Sui and Tang periods. Yuhou were the units responsible for reconnaissance and sentry duty, as well as command and leadership of forces in the field, supporting the authority of the high command by implementing its military law. The author argues that the Jinwuwei was an Imperial Guard unit acting in the role of yuhou under the command of the Tang Emperors. Secondly, the Jinwuwei, with the principle of yuhou at its core, was originally formed based on the concepts underlying the nomadic military organization of Xianbei 鮮卑, resembling the Mongolian pastoral bureaucracies of yūrtchī and bulārghūchī, demonstrating, in the author’s view, one occurrence of the nomadic elements which existed within the Sui and Tang Dynasty bureaucracies. Based on these findings, the author concludes that the military command authority of the Tang Emperors was intimately related to the Jinwuwei in the capacity of a yuhou unit, which was mobilized in order to deploy the whole Twelve Imperial Guards under the command of the Emperor. Moreover, the workings of military command authority in general—for example in the case of a special expeditionary force (hangjun 行軍) and regional military governors (jiedushi 節度使)—were similarly based on the yuhou system with its Xianbei nomadic character. From the above findings it is inferred that the Twelve Imperial Guards including the Jinwuwei retained the character of hangjun units under the Emperor’s military command.

The Pupils of Academicians (Boshi-Dizi 博士弟子) System, which was instituted in 124 BCE and the Imperial Institute of Learning (Taixue 太學), the highest seat of learning in ancient China dating back to the Zhou Dynasty, have been generally regarded as comprising one unified body. However, it remains uncertain whether the former was initially integrated with the latter, because neither of the documents relating to the establishment of the Boshi-Dizi System, Emperor Wu’s (Wudi 武帝) imperial edict and Gongsun Hong’s 公孫弘 petition, mention the Taixue, and Records of the Grand Historian (Shiji 史記), a contemporary work of historiography, contains no information indicating any such initial integration. This article considers the integration of the two institutions mainly from the perspective of the history of thought, beginning with an attempt to confirm the plan and aim of the initial Boshi-Dizi System. Next the author compares them with ideas about the Taixue which existed since antiquity and shows a significant departure between the two. This is followed by the introduction of Dong Zhongshu’s 董仲舒 concept of the Taixue, raising the possibility that although the Boshi-Dizi System adopted Dong’s ideas in part, it was initially an attempt to expand the existing institutions. Then the author turns to the subject of when and how the two institutions were eventually integrated, assuming integration occurred during the reigns of Emperors Yuan and Cheng (Yuandi 元帝 and Chengdi 成帝; 49–7 BCE), which were marked by institutional reform of the Han court along the lines of Confucian ideas. The author concludes by arguing that the integration should occupy an important place in the history of the growth of Confucianism because of its primary role in the establishment a “new” Han Taixue grounded in the study of the Confucian classics.

Along with development of the study of the Confucian classics (jingxue 經學) during the Han Period, there also appeared a related strain of mystic doctrine (chenwei 讖緯), related to the power of the emperors. The research to date on the use of chenwei-related works has indicated the possibility that although the writings on divination (tuchen 圖讖) done at the time of the enthronement of Later Han Emperor Guangwu (Guangwudi 光武帝; r. 25–57 CE) had no ideational connection to either Confucius or the Confucian classics, by the time of the fengshan 封禪 festivals of heaven and earth at Mt. Taishan 泰山, such prophetic writing was being influenced by Confucian ideas. The present article follows this research in considering exactly how Emperor Guangwu came to deal with chenwei works in connection with Confucian thought. To begin with, despite the fact that the theory that Confucius had written chenwei books to testify to the establishment and continued existence of the Han dynasty (Kong Qiu Mijing 孔丘秘經 Theory) had already appeared during the last years of the Xin Dynasty, the influence of Confucian chenwei thought was no widespread; and even after the uprising and enthronement of Emperor Guangwu, little interest was directed at the connection of chenwei to Confucianism. Rather, it was a time when the Emperor regarded chenwei as being effective in more concrete matters connected to rural life, the conquest of Hebei, etc. It was not until around the 6th year of Jianwu Era (30 CE) that Gongsun Shu 公孫述, the independent warlord of the Sichuan region, began operations to incite people by spreading the word of Confucian chenwei throughout Zhongyuan 中原. Meanwhile, beginning in the previous year, Emperor Guangwu had initiated various programs aimed at stabilizing the social crisis and chaos in the midst of military conflict through the introduction of Confucian ideas. Both movements were attempts to appeal to, agitate among and win the hearts of the people of Zhongyuan, who were by no means steadfast in loyalty to the Emperor Guangwu’s regime, by appealing to them, even if symbolically, with the then widely shared authority, i.e. Confucian ideas. The author concludes that the preconditions for these efforts, i.e. the penetration of Confucianism into Chinese society, led to the utilization of Confucian chenwei by Emperor Guangwu, through the political tensions at the beginning of the Later Han Period.

SATは計算機科学において最も単純で基本的な問題であるとともに,人工知能(AI)においても推論や制約充足のベースとなる重要な問題である.またSAT技術もアルゴリズム分野というよりは,AI研究の中で発展してきたことは注目に値する.本稿では,SATとAIの密接な関係を歴史的に概観し,SATがどれだけAIにインパクトを与えてきて,今後のAI 技術を左右し得るかについて予測する.SATは問題の構造が単純過ぎて(また理論的にもクラスNP に属するため)AIの本質的な複雑さには到底及ばないという意見があるにもかかわらず,SATの深遠さを知ることがAIに通ずることを本稿から読み取っていただきたい.

本稿では,対戦格闘ゲームにおけるゲームAI(AI)や操作法がプレイヤの感じる面白さに与える影響について分析する.対戦格闘ゲームには,キーボードなどの指先による操作と,Kinectを用いて体の動きで操作する方法がある.プレイヤがいずれの操作においても楽しく対戦格闘ゲームをプレイするためには,プレイヤと互角に戦うようなAIが必要である.また,それを実現させるためには強さをある程度持ったAIが必要である.本稿では,UCTをノード選択における戦略としたモンテカルロ木探索,ルーレット選択,ルールベースの手法を組み合わせることで,先述したAIを開発する.このAIをベースにし,UCTの評価関数を改変することによってプレイヤに合わせて強さを調整(難易度調整)するAIを開発する.そして,AIや操作法がプレイヤの感じる面白さに与える影響を,キーボード,Kinectのそれぞれの操作において分析する.対戦格闘ゲームの国際AI大会のプラットフォームとして利用されているFightingICEを用いた被験者実験より,難易度調整はプレイヤがより楽しんで対戦格闘ゲームをプレイするための重要な要素であり,特にKinectにおいて顕著な効果が示された.
