This paper presents the influence of various flexural strengthening design criteria specified by three important design guidelines (ACI440, TR55, FIB14) on the resulting strength, ductility and conservativeness of FRP strengthened RC elements. Various generalised mathematical relations in non-dimensional form are presented that can be employed to develop design aids for the FRP-strengthening process. A design methodology is prescribed based on these equations enabling the designer to optimally and intuitively incorporate sufficient ductility while designing for strength. In order to better interpret conservativeness within design codes, four distinct levels of embedded conservativeness are identified, which cover the entire range of sources of conservativeness. Finally, a detailed parametric study is presented, using the proposed design equations and methodology, to determine the influence of each of these four levels of conservativeness on final design solutions. Specific criteria that are useful while calibrating design guidelines are also presented.

이 글에서는 '전통'과 '이데올로기'를 바라보는 해석학적 논의를 통해서, 보수와 진보의 진정한 의미를 되새겨보고, 이를 통해 우리사회에서 전개되고 있는 이념 논쟁에서 타협의 방식을 간접적으로나마 찾아보고자 한다. 이를 위해서 먼저 가다머(H.G. Gadamer 1900~2002)와 하버마스(J. Habermas 1929~ ) 그리고 리쾨르(P. Ricoeur 1913~2005)를 중심으로 해석학이라는 분과학문이 전통과 어떤 식으로 관련되는지를 살펴보도록 한다. 이 과정에서 우리는 가다머 해석학의 보수적 측면과 하버마스 해석학의 진보적 측면을 확인할 수 있을 것이다. 여기서 보수적 입장과 진보적 입장에 대한 해석학적 의미를 살펴볼 것이다. 그리고 리쾨르의 시선을 좇아 가다머와 하버마스 해석학의 차이점과 공통점, 한계점과 보완점을 찾아낼 것이다. 그러니까 우리는 해석학적 종합을 통해서 보수 대(對) 진보라는 이념 문제의 해결 방식을 간접적으로 살펴보고자 한다.

Religion is deeply connected with human culture and life, and affects all areas of religious people's lives. The aim of this study was to find out how fashion-conservativeness of religious people and non-religious people differ in Korea. Ten religious people and ten atheists all in their twenties were interviewed to find out the differences between religious people and non-religious people related to their viewpoints on clothes. The twenties age group was selected because people in their twenties are sensitive to fashions and styles, and a fair proportion of males and females were selected. The subjects were asked demographic questions, questions about their religion and faith, whether or not they thought they were conservative or affected by religion, and finally, what they thought of photographs of certain styles. 12 photographs from the 2006-7 F/W collections of London, Paris, New York and Milan were presented to the subjects. The photographs were from the Vogue U.K. website and divided into 6 major styles based on verbal evidence used to describe the collections in catwalk reports: "Sexy," "attitude/confidence," "luxury," "sophisticated/chic," "feminine," and "rock." In conclusion, religious people were found to be more conservative than non-religious people in their twenties because they prefer more conservative and covered up styles, have more negative views of bold and skin-showing trends, and regard some styles to be too sexy when non-religious people do not.

It is important to calculate the exact crack opening area in the cracked pipe subjected to axial force and bending moment. Among many solutions for obtaining the crack opening displacement, Paris-Tada's expression, which is derived from energy method, is open used in fracture analysis for piping crack problems because of its simplicity. But Paris-Tada's equation has conservativeness when radius over thickness ratio(R/t) is ten or less, for it is based on the stress intensity factor solution having a compliance function derived from a simple shell theory. In this paper we derived a new expression using a different stress intensity factor solution which is able to consider the variation of compliance through wall thickness in a cracked pipe. Conservativeness of both equations was examined and compared to finite element analysis results. Conservativeness of the new equation is decreased when R/t > 10 and increased slightly when R/t < 10 compared with Paris-Tada's. But Both equations were highly conservative when R/t < 10 compared with finite element analysis results.

본 논문의 목적은 철학적으로 만족스러운 메타논리학으로서 부분전체론의 가능성을 살펴보는 것이다. 그 이유는 명백하다. 소위 수리 논리학으로 알려진 메타논리학에 대한 전통적인 접근은 집합들, 함수들, 모형들과 같은 수학적 존재자들의 존재를 미리 상정하고 있다. 이는 우리가 논리학을 개별 과학 분야에 적용할 때마다, 이러한 집합론적 메타논리학이 이들 분야의 논의영역에 언제나 이들 특수한 존재자들을 부가한다는 것을 의미한다. 이러한 사실은 집합론적 메타논리학이 논리학의 존재론적 보수성과 상충한다는 것을 보여준다. 반면에 집합론과 유사한 형식 체계인 부분전체론은 존재론적으로 무고하다고 주장되어 왔다. 따라서 우리가 논리학의 존재론적 보수성을 보장할 수 있는 중립적인 메타논리학으로 이 부분전체론을 고려하는 것은 상당히 자연스러운 일일 것이다. 하지만 부분전체론의 존재론적 무고함을 주장하는 논변들을 살펴보면, 우리는 부분전체론적 합 혹은 융합체와 같은 부분전체론적 존재자들이 존재론적으로 중립적인, 무고한 존재자가 아니라는 것을 알게 된다. 결국 우리는 부분전체론을 통한 메타논리학 역시도 논리학의 기초로서 올바른 접근이 될 수 없다고 결론 내리게 된다.

회화 문화재의 표장 및 보존처리에 쓰이는 풀은 그 문화재의 수명을 좌우할 정도로 중요하기 때문에 옛날부터 풀의 제조법에 관한 연구가 있어 왔고, 이에 대한 기록이 남겨져 왔다. 기록들을 종합해 보면, 대부분 풀의 제조법에 있어 소맥의 단백질을 제거하는 것에 대한 연구가 행해졌음을 알 수 있다. 이렇게 공통적으로 보여지는 단백질 제거는 단백질이 풀에 있어서 유익하지 못한 요소를 갖고 있다는 것이었다. 실제로 단백질 함유량에 따른 굴의 접착력과 보존성의 변화에 대한 실험을 해 보았는데, 그 결과를 종합해 보면, 미생물의 영양원인 단백질의 함량이 적을수록 접착력과 보존성은 좋아지지만, 유연성은 떨어졌다. 그러나 단백질의 함량이 적으면 적을수록 룰의 보존성은 좋아지기 때문에 회화 문화재 보존처리에 쓰여야 하는 풀은 보존성이 있고, 최소한의 농도로 최대한의 접착력을 지닌 또, 가역성이 있는 소맥 전분풀이었다.

This paper, which is an extension of a previous work by Viola et al. (2002), deals with the dynamic stability of beams under a triangularly distributed sub-tangential forces when the effect of an elastically restrained end is taken into account. The sub-tangential forces can be realised by a combination of axial and tangential follower forces, that are conservative and non-conservative forces, respectively. The studied beams become unstable in the form of either flutter or divergence, depending on the degree of non-conservativeness of the distributed sub-tangential forces and the stiffness of the elastically restrained end. A non-conservative parameter ${\alpha}$ is introduced to provide all possible combinations of these forces. Problems of this kind are usually, at least in the first approximation, reduced to the analysis of beams according to the Bernoulli-Euler theory if shear deformability and rotational inertia are negligible. The equation governing the system may be derived from the extended form of Hamilton's principle. The stability maps will be obtained from the eigenvalue analysis in order to define the divergence and flutter domain. The passage from divergence to flutter is associated with a noticeable lowering of the critical load. A number of particular cases can be immediately recovered.

A novel method of transient stability analysis is presented in this paper. The proposed method extracts data points near the basin-of-attraction boundary and then builds a support vector machine (SVM) model learned from the generated data. The constructed SVM classifier has been shown to reduce dramatically the conservativeness of the estimated basin of attraction.
