반이론주장의 조직불가능성명제는 윤리적 이론화의 불가능성에 대한 대표적인 근거이다. 특수주의가 강하게 반영된 이 명제를 통해 반이론가들은 구체적인 도덕적 상황에서 개개 행위자들이 내리는 결정들은 도덕원칙으로 조직화될 수 없기 때문에 윤리적 이론화는 불가능하다고 주장한다. 조직불가능성명제의 적절성은 이론적 차원에서 조직화의 대상이 도덕적 실제인지 아닌지의 쟁점을 통해, 그리고 실천적 차원에서 도덕원칙으로부터 도덕적 추론이 연역되는지 아닌지의 쟁점을 통해 검토될 수 있다. 먼저 실천적 숙고의 성격은 도덕적 실제 그 자체가 아니라 도덕적 실제를 넘어서는 도덕성이 조직화의 대상이라는 도덕이론가들의 주장을 뒷받침해준다. 또한 반이론가들의 비판과 달리 도덕이론가들은 도덕적 추론을 위해서 도덕원칙이외에도 상황적 지식과 행위자의 지혜에 근거한 도덕판단이 필요하다고 본다. 도덕이론가들은 다양한 도덕적 실제를 반영하는 행위자의 판단이 도덕성을 제시하는 도덕원칙을 통해 검토되고 이에 근거하여 도덕적 지위를 갖게 되는 형태의 윤리학을 추구한다. 결국 도덕이론가들은 복잡하고 다양한 도덕적 실제를 도덕원칙으로 조직화하거나 도덕원칙만으로 도덕적 추론이 가능하다고 주장하지 않기 때문에 조직불가능성명제를 통해 윤리적 이론화가 불가능하다는 것을 주장하려는 반이론가들의 시도는 성공적이지 못하게 된다.

This study is intended to understand an implication and significant of anti-design and Italian radical fashion. Anti-design and radicalism is the main stream or origin and essence of post-modernism which hs been swaying our society at large through modern culture, economy, art, fashion etc, from the latter part of 1960s. In this paper, the author classified the italian radical fashion with the Archizoom, the Alchymia, the memphis fashion. In post-modernism fashion, radical fashion design of the Archizoom, Alchymia and Memphis group is in part a menifesto and in part a noncanonical history of the most progressive and heretical experiments of the world of fashion. Anti-designers of Italy call for a theory an practive in which the old methods and instruments and the old commendments of modernism are banished. They looked on fashion as material culture, a creative field with its own independent foundation and endowed with its own strong artistic intuition. IF radical design is dead, the energy it has stirred up is still alive nd kicking. One of the most progressive and well-informed culture milieus in Milian, seved as a point of reference for the vanguard of fashion.

Network security situation prediction is difficult due to its strong uncertainty, but DS evidence theory performs well in solving the problem of uncertainty. Based on DS evidence theory, this study analyzed the prediction of the network security situation, designed a prediction model based on the improved DS evidence theory, and carried out a simulation experiment. The experimental results showed that the improved method could predict accurately in the case of a large conflict, and had strong anti-jamming abilities as compared with the original method. The experimental results prove the effectiveness of the improved method in the prediction of the network security situation and provide some theoretical basis for the further application of DS evidence theory.

The present paper addresses a refined plate theoryin order to describe the response of anti-symmetric cross-ply laminated plates subjected to a uniformlydistributed nonlinear thermo-mechanical loading. In the present theory, the undetermined integral terms are used and the variables number is reduced to four instead of five or more in other higher-order theories. The boundary conditions on the top and the bottom surfaces of the plate are satisfied; hence the use of the transverse shear correction factors isavoided. The principle of virtual work is used to obtain governing equations and boundary conditions. Navier solution for simply supported plates is used to derive analytical solutions. For the validation of the present theory, numerical results for displacements and stressesare compared with those of classical, first-order, higher-order and trigonometricshear theories reported in the literature.

In this scientific work, an analytical solution for the dynamic analysis of cross-ply and angle-ply laminated composite plates is proposed. Due to technical issues during the manufacturing of composite materials, porosities and micro-voids can be produced within the composite material samples, which can carry on to a reduction in the density and strength of the materials. In this research, the laminated composite plates are assumed to have new distributions of porosities over the plate cross-section. The structure is modeled using a simple integral shear deformation theory in which the transverse shear deformation effect is included. The governing equations of motion are obtained employing the principle of Hamilton's. The solution is determined via Navier's approach. The Maple program is used to obtain the numerical results. In the numerical examples, the effects of geometry, ratio, modulus ratio, fiber orientation angle, number of layers and porosity parameter on the natural frequencies of symmetric and anti-symmetric laminated composite plates is presented and discussed in detail. Also, the impacts of the kinds of porosity distribution models on the natural frequencies of symmetric and anti-symmetric laminated composite plates are investigated.

그레마스의 기호학은 언어텍스트뿐만 아니라 비언어텍스트의 분석에 유용한 것으로서, 특히 담화구조와 관련된 이론을 통하여 스타크래프트의 멀티플레이를 분석해보았다. 스타크래프트의 담화는 그것이 완성되어 주어진 담화가 아니라는 점에서 다른 매체의 담화와는 두드러지게 다른 특성들을 보여주는데, 가장 대표적인 것이 담화를 생산해가고 있는 주체와 반주체라는 존재였다. 이들은 수동적인 존재가 아니며 능동적으로 발화자, 피발화자의 위치를 교차시키며 역동적인 담화를 생성해낸다.

A new analytical solution based on a third order shear deformation theory for the problem of static analysis of cross-ply doubly-curved shells is presented. The boundary-discontinuous generalized double Fourier series method is used to solve highly coupled linear partial differential equations with the mixed type simply supported boundary conditions prescribed on the edges. The complementary boundary constraints are introduced through boundary discontinuities generated by the selected boundary conditions for the derivation of the complementary solution. The numerical accuracy of the solution is compared by studying the comparisons of deflections, stresses and moments of symmetric and anti-symmetric laminated shells with finite element results using commercially available software under uniformly distributed load. Results are in good agreement with finite element counterparts. Additional results of the symmetric and anti-symmetric laminated and sandwich shells under single point load at the center and pressure load, are presented to provide data for the unsolved boundary conditions, benchmark comparisons and verifications.

To cope with the complex electromagnetic environment of wireless communication systems, anti-jamming decision methods are necessary to keep the reliability of communication. Basing on the rule-reduced genetic algorithm (RRGA), an anti-jamming decision method is proposed in this paper to adapt to the fast channel variations. Firstly, the reduced decision rules are obtained according to the rough set (RS) theory. Secondly, the randomly generated initial population of the genetic algorithm (GA) is screened and the individuals are preserved in accordance with the reduced decision rules. Finally, the initial population after screening is utilized in the genetic algorithm to optimize the communication parameters. In order to remove the dependency on the weights, this paper deploys an anti-jamming decision objective function, which aims at maximizing the normalized transmission rate under the constraints of minimizing the normalized transmitting power with the pre-defined bit error rate (BER). Simulations are carried out to verify the performance of both the traditional genetic algorithm and the adaptive genetic algorithm. Simulation results show that the convergence rates of the two algorithms increase significantly thanks to the initial population determined by the reduced-rules, without losing the accuracy of the decision-making. Meanwhile, the weight-independent objective function makes the algorithm more practical than the traditional methods.
