東海道・山陽新幹線の列車運行管理システムである COMTRAC(COMputer aided TRAffic Control)-Hは1975年5月より稼動を開始している.このシステム構成は 進路制御の機能を担う制御用計算機と運転整理の機能を分担する汎用計算機が階層的に結合されたものである.本報告では 列車ダイヤに乱れが生じたときに 人間と機械の会話により迅速にダイヤを収拾する運転整理システムの性能評価をシステム開発の前段階で行い 設計に反映させた例について述べる.運転整理システムの特徴は 列車に乱れが生じた際に成される指令行為が計算機に急激な負荷をもたらす点にある.したがって システム設計にあたっては 指令員の投入したコマンドに対する応答時間とスループットを共に確保する処理方式を確立する必要がある.この理由から 運転整理システムのシミュレーション・モデルを開発し 想定した入力負荷に対する特性を分析した.この分析結果から 応答時間に占める主要因は (1)計算機間の交信 (2)異なる優先順位を持つタスク間の交信 そして(3)ファイルの競合にあることが判明した.以上から 制御用計算機と汎用計算機間の交信周期の最適化を計ること および 優先度の高いタスクの処理を分割することを提案し システム設計に反映させた.この結果 運転整理システムは充分な応答時間とスループットを満足するシステムとして現在稼動している.

In classical Athens unmarried girls, like adults and boys, also took part in some honorable rituals. This article focuses on the 'Arkteia', which was performed by girls in Brauron, one of the sanctuaries of Artemis in Attica. Most scholars have regarded the Arkteia as a ritual for girls entering maturity. However, some scholars have challenged this view, citing some contradictory literary sources. This paper shows that this ritual was not only a maturation rite in which young women participated, but that it also encouraged them to adapt to their future life as Athenian women. Firstly, this paper reexamines whether or not the Arkteia was a maturation rite, and reconsiders its age qualification. Literary sources attest that the girls who participated in the ritual wore 'krokotoi' (saffron robes) indicating that they were sexually mature women. The legend of Iphigeneia, who is associated with Brauron, also alludes to this ritual as marking the passage of young women into maturity. The Arkteia was therefore a maturation rite for girls, as previous scholarship has claimed. However, there is room for reconsidering the age qualification of 5-10 years, as this age group would have been ineligible for this particular type of ritual. Based on an investigation of various sources, this article suggests that this age qualification is not reliable. Secondly, this paper investigates the relationship between the Arkteia and the dedication performed by women for Artemis in Brauron. Women worshipped Artemis because she took care of mothers, childbirth and children. Many adult women dedicated expensive items to Artemis in Brauron, in expectation of her protection in gynecopathy or in childbirth, and her protection of their children. It seems that the girls who served as 'arktoi' (participants in the Arkteia) and the women who dedicated goods to Artemis were of an equivalent economic class. This means that the arktoi offered items to Artemis after they had reached maturity. The treasure records of Artemis Brauronia (an epigraphic source) indicate that most of the votive offerings were items of clothing and that some of these were exhibited in the temple of Artemis. In addition, an inventory was erected along the wall of the temple and on a large stoa in the sanctuary. These facts suggest that girls who participated in the Arkteia learned the ways of life of Athenian women by means of the many votive offerings and the lengthy inventory. It is worth noting that some of the clothes displayed in the temple reminded the girls of important work; weaving. This would have been how the girls were transformed into the 'Athenian women' that Athenian society, specifically Athenian men, demanded.

This paper examines the character of professional responsibility, mainly with reference to the theory of common morality and particular moralities by Beauchamp and Childress. Furthermore, it examines the concepts of generality and particularity in normative ethical theories, the attitude approach and the role morality argument by Bowie, and two usages of reason by Kant. The professional responsibility is considered as a special role morality, which depends on some specialized and specific norms rather than on the general norms from the abstract principles. The theory of common morality and particular moralities has some persuasiveness, and it has the possibilities of being developed as a comprehensive normative ethical theory. However, there remains a question concerning the foundation of moral pluralism, and an issue of how usual moral judgments are located in their theory.

The East African dominions of the Arab dynasty Būsaʻīd centering on Zanzibar experienced a commercial heyday in the midst of the flourishing maritime trade of the mid-19th century. Following the entry of North American and European merchants into East African waters beginning in the early part of that century, a Būsaʻīdī-British commercial treaty was concluded in 1839. This article attempts to clarify the yet-to-be-examined process of the establishment of the British consular court in Būsaʻīdī East Africa through an analysis of British Indian sources from two distinct epochs.The first epoch, dated a few years before and after 1842, marked the arrival of the first British consul in Zanzibar. Through an examination of cases occurred at that time concerning criminal behavior, which was not covered by the treaty, the author finds that both the Būsaʻīdī and British authorities handled the cases with mutual deference, as exemplified by measures taken by the Būsaʻīdī sovereign in one case and the surrender of an Englishmen accused of murder. Regarding both criminal and civil cases after that epoch, a custom was being formed based on the principle that a defendant's nationality determined the court of jurisdiction.The second epoch, dated a few years before and after 1866, was marked by the procedures of the consular court becoming part of English domestic jurisprudence. The demands of the British consular officers who had been forced to determine criminal justice without any ground in English law deter- mined the legislation concerning the consular court at Zanzibar. An increase in both the number of and the amount claimed in civil suits filed at the court after the legislation clearly shows expanding use of the court as an option for the settlement of disputes. The research to date on the consular court presents a fairly linear account of increasing British influence in Būsaʻīdī East Africa after the conclusion of the commercial treaty, ending with the sultanate's eventual subjugation as Zanzibar Protectorate. However, as the author has shown, the institutional framework of the consular court at Zanzibar was by no means completed in one single stroke, nor was it entirely forced upon the Būsaʻīd by the British. Rather, this framework was formed gradually over a span of 30 years through the careful handling of actual cases by the both authorities via negotiations conducted between them.
