Fasad i.e. venesection is an old classical method of treatment in the Unani system of medicine. Fasad is Arabic word which means "to open". In the process, complete evacuation which drains out blood and dominating humours mixed with blood from veins. Fasad is carried out when the kamiyat (quantity) of the blood is excess in the body and patient is either exposed to the risk of developing a disease or has actually developed one. In classical literature of Unani system of medicine, physicians wrote a lot about this procedure. The details of venesection is mentioned in the given paper on the basis of classical literature including history, indications, types, amount of blood to be venesected, time, person, procedure, complications and special focus has been made on the number of vessels to be venesected and their benefits with respected to disease and condition.

Gradient elastic flexural beams are dynamically analysed by analytic means. The governing equation of flexural beam motion is obtained by combining the Bernoulli-Euler beam theory and the simple gradient elasticity theory due to Aifantis. All possible boundary conditions (classical and non-classical or gradient type) are obtained with the aid of a variational statement. A wave propagation analysis reveals the existence of wave dispersion in gradient elastic beams. Free vibrations of gradient elastic beams are analysed and natural frequencies and modal shapes are obtained. Forced vibrations of these beams are also analysed with the aid of the Laplace transform with respect to time and their response to loads with any time variation is obtained. Numerical examples are presented for both free and forced vibrations of a simply supported and a cantilever beam, respectively, in order to assess the gradient effect on the natural frequencies, modal shapes and beam response.

In this study, clustering of black BADUK stones' image were performed to recognize the individual stone from its closely spaced and partially occluded Image. And the clustering perfomance was compared between the classical methods and fuzzy C-means method. As a result, 2 BADUK stones' image was segmented precisely in every methods, but more than 3 stones the segmentation was depended on its shape. Fuzzy C-means method could be segmented correctly to 4 stones regardless of its shape, and It could be applied to the unknown number of clusters.

In a development of efficient primal-dual interior-points algorithms for self-scaled convex programming problems, one of the important properties of such cones is the existence and uniqueness of "scaling points". In this paper through the identification of scaling points with the notion of "(metric) geometric means" on symmetric cones, we extend several well-known matrix inequalities (the classical L$\ddot{o}$wner-Heinz inequality, Ando inequality, Jensen inequality, Furuta inequality) to symmetric cones. We also develop a theory of spectral geometric means on symmetric cones which has recently appeared in matrix theory and in the linear monotone complementarity problem for domains associated to symmetric cones. We derive Nesterov-Todd inequality using the spectral property of spectral geometric means on symmetric cones.

본고에서는 <전우치전> 경판본 계열 중 선본으로 볼 수 있는 한국학중앙연구원 소장본을 중심으로 <전우치전>이 갖는 교육적 가치를 살펴보고, <전우치전>을 가지고 학생들에게 어떠한 방법으로 가르칠 것인가 하는 활용방안에 대해서 알아보았다. <전우치전>이 갖는 교육적 가치로 "민중의 원한 해소, 과욕의 징치, 효와 충, 그리고 불충의 대립"을 들어 설명하였다. 그리고 교육의 활용방안으로는 브레인스토밍과 논증/논술 방법을 예로 들었다. 시대가 바뀌면서 고소설에 대한 인식을 고정적으로 가질 수는 없다. 현재를 살아가는 학생들에게 전 시대의 작품을 어떠한 방식으로 가르치고 설명할 것인지를 생각해 보았다. 그리고 학생들은 자신이 가진 생각을 어떻게 조리 있게 글로 쓸 수 있을까를 고민했다.

Coded cooperation is a promising user cooperation scheme. In this paper, we first propose a novel network-coding-based coded cooperation scheme. When a user decodes its partner's information correctly in the first frame, it transmits the combination of the partner's parity bits and its own parity bits through network coding in the second frame. This is distinct from the classical scheme, where the user only transmits the partner's parity bits during cooperation. We analyze the outage probability of the proposed scheme, and show that it achieves a full diversity order. Numerical evaluations reveal that the proposed scheme outperforms the classical scheme when the inter-user channel is poor, yet is worse when the inter-user channel is strong. Also, the results show that the proposed scheme always outperforms that of no cooperation in various channel conditions while the performance of classical scheme is worse than that of no cooperation with the poor inter-user channels. This means that the performance of the proposed scheme is more stable than the classical scheme and the proposed scheme is more tolerant to the poor inter-user channels. To combine the advantages of the proposed scheme and the classical scheme under different inter-user channel conditions, we propose an adaptive solution. This adaptive scheme enhances the system performance considerably in all channel conditions in spite of the inter-user channel quality, at the expense of only one acknowledgement or non-acknowledgement bit.

The aim on this paper is to explain the present state and circumstance in the course of arranging historic classical books in China. In order to approach its purpose, it should make it clear to define the word of "The present"(當代). Furthermore, we need to take a deep notice on the arrangements itself of historic classical books, its influences and contributions, reflecting this process carefully with those historical, cultual and social points of view due to the meaning of "The present" in China. Starting from this considerate view, first of all, I would like to determine the accurate time of "The present" to be the period of time from October, 1949 to December, 2003. It can be described very suitably well as "bamboo sprouts grow fast after a rainfall"(雨後春荀). This tremendous works in the arrangements of Classics have gone through sweets and bitters of times during 50 and several years. However, this work in process has overcome so much troubles and exclude obstacles in doing so, gradually begun to bear tasteful fruit of many publications, about 10,000 works so far. Although it has gone far with very little amount of works in comparison with the remains that would be put in order in the incoming future, it succeed effectively to the spirit and soul in Chinese culture and people. Illuminating the development in its historical steps and analyzing elaborately flows in cultural and ideal elements, it is known that this work of arrangements not only give a very firm basis for excellent Chinese cultural tradition, but also extend high level of idea and thoughts in their thoughts so that build up the spirit in socialism on the solid foundation. This paper will give a explanation and analysis on this works and its contributions. At the same time, it examine and give a good, careful, and close look on the arrangement of historic classical books in China by various means of classifying into various types and style, searching for many methods, and showing indication and directions that might be right in "the present".

This paper presents a dynamic analysis of three-dimensional beams. Structures made of functionally graded materials are considered. Several higher-order as well as classical theories are derived by means of a compact notation for the a-priori expansion order of the displacement field over the beam cross-section. The governing differential equations and boundary conditions are obtained in a condensed nuclear form that does not depend on the kinematic hypotheses. The problem is, then, exactly solved in space by means of a Navier-type solution, whereas time integration is performed by means of Newmark's solution scheme. Slender and short simply supported beams are investigated. Results are validated towards three-dimensional FEM results obtained via the commercial software ANSYS. Numerical investigations show that good accuracy can be obtained through the proposed formulation provided that the appropriate expansion order is considered.

We continue the study of fully idempotent rings initiated by Courter. It is shown that a (semi)prime ring, but not fully idempotent, can be always constructed from any (semi)prime ring. It is shown that the full idempotence is both Morita invariant and a hereditary radical property, obtaining $hs(Mat_n(R))\;=\;Mat_n(hs(R))$ for any ring R where hs(-) means the sum of all fully idempotent ideals. A non-semiprimitive fully idempotent ring with identity is constructed from the Smoktunowicz's simple nil ring. It is proved that the full idempotence is preserved by the classical quotient rings. More properties of fully idempotent rings are examined and necessary examples are found or constructed in the process.
