Okakura Kakuz$\bar{o}$ (1863-1913), the founder of the Japan Art Institute, is best known for his proclamation, "Asia is One." This phrase in his book, The Ideals of the East, and his connections to Bengali revolutionaries resulted in Okakura being remembered as one of Japan's foremost Pan-Asianists. He did not, however, write The Ideals of the East as political propaganda to justify Japanese aggression; he wrote it for Westerners as an exposition of Japan's aesthetic heritage. In fact, he devoted much of his life to the preservation and promotion of Japan's artistic heritage, giving lectures to both Japanese and Western audiences. This did not necessarily mean that he rejected Western philosophy and theories. A close examination of his views of both Eastern and Western art and history reveals that he was greatly influenced by Hegel's notion of dialectics and the evolutionary theories proposed by Darwin and Spencer. Okakura viewed cross-cultural encounters to be a catalyst for change and saw his own time as a critical point where Eastern and Western history was colliding, causing the evolution of both artistic cultures.

Based on the value of the Lagrange multiplier and the degree of constraint activeness, a new update rule is proposed for penalty parameters of the ALM method. The theoretical exposition of this suggested update rule is presented by using the algorithmic interpretation and the geometric interpretation of the augmented Lagrangian. This interpretation shows that the penalty parameters can effect the performance of the ALM method. Also, it offers a lower limit on the penalty parameters that makes the augmented Lagrangian to be bounded. This lower limit forms the backbone of the proposed update rule. To investigate the numerical performance of the update rule, it is embedded in our ALM based dynamic response optimizer, and the optimizer is applied to solve six typical dynamic response optimization problems. Our optimization results are compared with those obtained by employing three conventional update rules used in the literature, which shows that the suggested update rule is more efficient and more stable than the conventional ones.

작년(1977년) 9월 20일부터 29일까지 10일간 서독 Hannover 에서 세계 28개국이 최신, 정예 각종 공작기게를 출품 전시한 제2회 구라파 국제 공작기계전시회 [2. EMO (Exposition Europeennne de Ia Machine-Outil a participation mondiale, European Machine Tool Exhibition with worldwide participation)]이 대성황리에 열려었다. 필자는 당시, 서독 Karlsruhe 대학기계공학부 의 공작기계 및 작업기술(Werkzeugmaschinen und Betriebstechnik)연구소에서 1년간 체유하고 있을 때 이었으므로 개최 2,3개월전서부터 그 날을 손 꼽아 기다리고 있던 중 필자가 있던 동 연 구소에서 소원 각자의 차로 9월 24일부터 10월 2일까지 Hannover에 가서 동전시회를 보고 기타 지역의 몇개 공장과 공대 기계공학부를 방문한다고 하여 이에 동행하였었다. 동 연구소에서는 약 10월간의 여행경비일절을 다 부담해 주는 호의까지 베풀어 주어 물심양면으로 신세를 많이 지면서 Hannover 전시장에 전시된 세계의 공작기계를 볼 수가 있었다. 이것은 그 중 Hannover 전시회에 가서 어데서부터 봐야 빠짐없이 다 볼수 있을지를 몰라서 흥분된 마음과 놀랜 눈으로 이리 뛰고 저리 뒤며 보고 듣고 그리고 느낀 것을 간추려 쓴 것이다.

Biomimetic apatite deposition behaviors on Zr-1Nb and Ti-6Al-4V plate with various surface conditions were examined. Both alloys were polished with abrasive papers to have different roughness and some of them were treated in NaOH before exposition in simulated body fluid. NaOH treatment was found to enhance the deposition rate of apatite on Ti-6Al-4V significantly. On the other hand, the deposition rate of Zr-1Nb was not influenced by NaOH treatment. Without NaOH treatment, the polished Zr-1Nb with abrasive paper was found to induce more apatite nucleation than the polished Zr-6Al-4V.

Fredrick Krause's chair in the Brooklyn Museum of Art (accession no. 87. 19) is a key to the understanding of factory-made, patent furniture, and the Modern Gothic style in the United States. However, research has rarely done for this chair as well as for the designer. Since this piece is incorporating the utility patent, it is a valuable example to understand the nineteenth-century patented furniture. Because of the popularity of Modern Gothic style, the similar style of chairs were often manufactured. This study explores how other examples are related and what the significance of the Brooklyn Museum chair is. The book of Sharon Darling provided especially helpful information about other Krause chairs in Fond du Lac and chair manufactures in Chicago. The interview with John Ebert at Galloway House in Fond du Lac, Wisconsin was especially helpful. Several primary sources proved helpful in researching the chair. The photo archives. of Kimbel and Cabus at the Cooper-Hewitt National Design Museum provides me a key to this research.

VoIP technology is a technology for exchanging voice or video data through IP network. Various protocols are used for this technique, in particular, RTP(Real-time Transport Protocol) protocol is used to exchange voice data. In recent years, with the development of communication technology, there has been an increasing tendency of services such as "Kakao Voice Talk" to exchange voice and video data through IP network. Most of these services provide a service with security guarantee by a user authentication process and an encryption process. However, RTP protocol does not require encryption when transmitting data. Therefore, there is an exposition risk in the voice data using RTP protocol. We will present the risk of the situation where packets are sniffed in VoIP(Voice over IP) communication using RTP protocol. To this end, we configured a VoIP telephone network, applied our own sniffing tool, and analyzed the sniffed packets to show the risk that users' data could be exposed unprotected.

The object of the offering exposition is to study almost Ricci soliton and gradient almost Ricci soliton in 3-dimensional para-Sasakian manifolds. At first, it is shown that if (g, V, λ) be an almost Ricci soliton on a 3-dimensional para-Sasakian manifold M, then it reduces to a Ricci soliton and the soliton is expanding for λ=-2. Besides these, in this section, we prove that if V is pointwise collinear with ξ, then V is a constant multiple of ξ and the manifold is of constant sectional curvature -1. Moreover, it is proved that if a 3-dimensional para-Sasakian manifold admits gradient almost Ricci soliton under certain conditions then either the manifold is of constant sectional curvature -1 or it reduces to a gradient Ricci soliton. Finally, we consider an example to justify some results of our paper.

This work presents an exposition of both the internal structure of derived category of an abelian category D^*(𝓐) and its contribution in solving problems, particularly in algebraic geometry. Calculation of some morphisms will be presented between objects in D^*(𝓐) as elements in appropriate cohomology groups along with their compositions with the help of Yoneda construction under the assumption that the homological dimension of D^*(𝓐) is greater than or equal to 2. These computational settings will then be considered under sheaf cohomological context with a particular case from projective geometry.
