The Essence of Li (Rites) and Its Modern Significance By Ogyu Sorai

( Hiraishi Naoaki ) 성균관대학교 동아시아학술원 2003 Sungkyun Journal of East Asian Studies Vol.3 No.2

Ogyu Sorai, a seventeenth-eighteenth century Confucian scholar of Japan during the Tokugawa Shogunate, developed his own unique interpretation of the dynasties ruled by the ancient Chinese sage emperors and later dynastic generations. He sought the essential elements in governing people in li (rites). Turning to the contemporary Tokugawa society at that time in Japan, he published his own commentaries and recommendations for a stable society and generation by applying the principle of rites. Sorai argued a society based on the principle of rites would bring stability to the people and benevolence to the administration. Sorai more specifically agued about the application of the principle of rites to suppress the luxurious life in society to stabilize society and the effects of rites in educating the people on social norms.

禮的本質及其現代意義 - 以荻生徂徕的學說爲線索 -

( Hiraishi Naoaki ) 성균관대학교 유교문화연구소 2003 儒敎文化硏究(中文版) Vol.3 No.-

This article discusses the nature of ritual and its modern significance. To do this, it analyzes how the Confucian scholar Ogyū Sorai in the Tokugawa period thought about the "ritual" of Confucianism and how he tried to put it into practice in his own time. To answer this question, Ogyū Sorai investigated the positive significance of the ritual and music system of ancient Chinese saints in Tokugawa society, which is different in time and region, and proposed a system reform plan to General Tokugawa along this idea. By studying his thoughts, we may be able to obtain useful enlightenment for thinking about the above-mentioned problems for us who are living in the contemporary era. A review of this will make us realize that there are several issues that need to be considered when examining the meaning of ritual today. We can answer such questions like who established Ii (adult), how it was established (an investigation of perfection and historical conditions), how its suitability was demonstrated (how many years the dynasty lasted), and what purpose we want to achieve through consciousness (comfort and benevolent governance).

DES Technology

DES(Discrete Event Systems) are a class of systems in which occurrence of events drive systems. Each event occurs at an instant in time and marks a change of state in the system. Theory of DES provides basis for design and analysis of software/handware systems with discrete stats. In this paper, we describe how the theory and algorithms on DES can contribute to design of highly-dependable embedded systmes.

Teaching of English and American Literature in Japan: A Brief Survey

Takaki Hiraishi 한국영미문학교육학회 2003 영미문학교육 Vol.7 No.1

Many scenes of heated discussion have recently been witnessed in Japan on the question of education of English literature in colleges and universities. A growing number of Japanese teachers of English literature are now trying to help students understand cultures of the English-speaking world, some of them particularly interested in what is called "cultural studies"; meanwhile, teachers supporting the traditional view, not necessarily elderly teachers, maintain that teaching of literature is a matter of education, not a matter of literature, and cultural studies is a branch of sociology, not of literature. The culture-oriented method is in fashion now because it keeps pace not only with recent trends of literary criticism but with various social changes in the post-War Japan. but nobody is able to see clearly if it solves the difficult question of education of literature once and for all, as is shown by a questionnaire made by a literary journal in 2002.

The content distribution services via the Internet have become popular. However these services have some problems that prevent users from getting a file efficiently and there still remains much room for improving. In this paper, we focus on representative hybrid P2P[1] network application, BitTorrent[2], and try to resolve these problems. We propose the method for placing transfer support nodes, called "SupportNode", by service providers to allow users to get contents efficiently and evaluate the method by using computer simulation.

A Faster Approximation Technique for Predicate Abstraction of Hybrid Systems

Kunihiko HIRAISHI,Koichi KOBAYASHI 제어로봇시스템학회 2009 제어로봇시스템학회 국제학술대회 논문집 Vol.2009 No.8

Predicate abstraction is a powerful technique for extracting finite-state models from infinite-state systems, and is applied to verification of safety properties. In this paper, we propose a technique that can be used for accelerating the computation of abstract state spaces for hybrid system. The technique is based on upper approximation of the state transition relation, and requires a polynomial number of reachability checks and Boolean operations to compute the abstract state space consisting of a (possibly) exponential number of abstract states.

요코이 쇼오난(橫井小楠)의 사상적 리더십

平石直昭(HIRAISHI NAOAKI) 한국동양정치사상사학회 2002 한국동양정치사상사연구 Vol.1 No.2

바쿠후 말기 유신기의 변동기에는 사상가가 일본의 장래를 방향짓는데 중대한 역할을 했다. 서양문명과의 접촉에 의해, 어쩔 수 없이 국내의 정치사회체제가 재편 되어야 했으며, 그 과정에서 많은 일본인들이 기존의 세계상이나 가치기준을 회의하고, 그것을 대신하는 새로운 체제의 구상과 사고틀을 추구했기 때문이다. 거기에는 사상적, 사회적 혼란 가운데, 사람들이 자신의 위치를 확인하고, 나아가야 할 방향을 정하기 위한 새로운 나침반이 필요로 한다는 사정이 있었다. 그 가운데 유교사상가로서 출발한 요코이 쇼오난은 유교의 개념을 引照基準으로 삼아 서양의 정치체제나 산업사회의 양태를 내내적으로 이해하고 평가하면서, 다른 한편으로 서양국가가 이해의 타산을 정치외교의 원리로 삼고 있는 점을 비판하고. 인류의 相互利他라는 관점에서 세계평화를 주창, 일본은 그런 이념을 내걸고 세계에서의 분쟁 해결에 노력해 ‘세계의 남의 일을 돌봐주는 나라’가 되어야 한다고 주장했다. 그것은 근대 유럽에서 발달한 의회제나 국제법 사고에 들어맞는 관념을 보여주고 있으며, 유교적인 보편주의의 극한화라 할 수 있다. 거기에는 전환기에 있어 하나의 사상적 리더쉽을 보여주고 있다. 다만 그 시대의 정치사상을 이해하기 위해서는, 시대의 동요가 단순히 지적, 도덕적 레벨에 머물지 않고, 보다 근본적으로 종교적 레벨과 관련되어 있다는 점에 주의할 필요가 있다. 다시 말해서 사람이 이 세상에서 살고 죽는 것의 의미를 근본적으로 묻게 되며, 정치사상은 그 문제에 답함으로써 사람들의 지지를 얻을 수 있었다는 것, 그리고 그 회답 방식(삶과 죽음의 의미부여)의 차이에 따라, 정치사상의 큰 차이를 낳게 된다. 쇼오난의 경우, 그 정치사상은 보편주의적인 ‘천(天)’ 이념을 중심에 두고 있으며, 독자적인 종교성을 띠고 있다. 본고에서는, 동시대의 미토가구와 히라타 코쿠가구에서, 생사관과 정치사상이 어떻게 관련되어 있는지를 쇼오난 사상과 비교검토함으로써, 쇼오난 사상의 특징을 규명하려고 했다.

Effect of phytic acid as an endodontic chelator on resin adhesion to sodium hypochlorite-treated dentin

Objectives: Phytic acid (IP6), a naturally occurring agent, has been previously reported as a potential alternative to ethylenediaminetetraacetic acid (EDTA). However, its effect on adhesion to sodium hypochlorite (NaOCl)-treated dentin and its interactions with NaOCl have not been previously reported. Thus, in this study, the effects of IP6 on resin adhesion to NaOCl-treated dentin and the failure mode were investigated and the interactions between the used agents were analyzed. Materials and Methods: Micro-tensile bond strength (µTBS) testing was performed until failure on dentin treated with either distilled water (control), 5% NaOCl, or 5% NaOCl followed with chelators: 17% EDTA for 1 minute or 1% IP6 for 30 seconds or 1 minute. The failed specimens were assessed under a scanning electron microscope. The reaction of NaOCl with EDTA or IP6 was analyzed in terms of temperature, pH, effervescence, and chlorine odor, and the effects of the resulting mixtures on the color of a stained paper were recorded. Results: The µTBS values of the control and NaOCl with chelator groups were not significantly different, but were all significantly higher than that of the group treated with NaOCl only. In the failure analysis, a distinctive feature was the presence of resin tags in samples conditioned with IP6 after treatment with NaOCl. The reaction of 1% IP6 with 5% NaOCl was less aggressive than the reaction of the latter with 17% EDTA. Conclusions: IP6 reversed the adverse effects of NaOCl on resin-dentin adhesion without the chlorine-depleting effect of EDTA.
