In this study, element loading matrices are defined for static application of classical M$\ddot{u}$ller-Breslau principle to finite element method. The loading matrices are derived from existing element matrices using Betti's law and known governing equations of F.E.M. Thus, the ordinates of influence lines and influence surfaces may be easily obtained from structural analysis for the loading matrices derived from governing equations, instead of through introduced unit force or displacement techniques. An algorithm for a computer program and comparative numerical examples are also presented to illustrate the procedure for determination of influence line and surface ordinates.

In an era where the international investment and trade between Korea and China grow daily, the importance of international arbitration cannot be overstated. The Korean Arbitration Law was enacted with reference to the UNCITRAL Model Law. When the Chinese Arbitration Law was being enacted, the UNCITRAL Model Law was also referred to, but there are some discrepancies between the two. This article conducts comparative analysis based on the Korean and the Chinese Arbitration Laws, the Chinese Civil Procedure Law and the KCAB and the CIETAC arbitration rules. In order to adopt the UNCITRAL Model Law amended in 2006, Korea revised its Arbitration Law in 2016. The revised Law includes a more comprehensive legal regime regarding interim measures, emergency arbitrator, etc. In China, the enforcement of foreign-related arbitral awards and foreign arbitral awards is carried out mainly by intermediate people's courts. In China, the report system to the higher people's court for refusing the enforcement of foreign-related arbitral awards and for refusing the recognition or enforcement of foreign arbitral awards has the effect of safeguarding foreign-related arbitral awards and foreign arbitral awards in China. Both Korea and China joined the New York Convention, and domestic courts may refuse the recognition and enforcement of foreign arbitral awards according to the New York Convention.

In this study, the semi-analytical finite strip method is adopted to examine the free vibration of cylindrical shells made up of functionally graded material. The properties of functionally graded shells are assumed to be temperature-dependent and vary continuously in the thickness direction according to a simple power law distribution in terms of the volume fraction of ceramic and metal. The material properties of the shells and stiffeners are assumed to be continuously graded in the thickness direction. Theoretical formulations based on the smeared stiffeners technique and the classical shell theory with first-order shear deformation theory which accounts for through thickness shear flexibility are employed. The finite strip method is applied to five different shell theories, namely, Donnell, Reissner, Sanders, Novozhilov, and Teng. The approximate procedure is compared favorably with three-dimensional finite elements. Finally, a detailed numerical study is carried out to bring out the effects of power-law index of the functional graded material, stiffeners, and geometry of the shells on the difference between various shell theories. Finally, the importance of choosing the shell theory in simulating the functionally graded cylindrical shells is addressed.

In the current research, a displacement-based seismic design scheme to retrofit reinforced concrete columns using FRP composite materials has been proposed. An accurate prediction for the nonlinear flexural analysis of FRP jacketed concrete members has been presented under multiaxial constitutive laws of concrete and composite materials. Through modification of the displacement coefficient method (DCM) and the direct displacement-based design method (DDM) of reinforced concrete structures, two algorithms for a performance-based seismic retrofit design of reinforced concrete columns with a FRP jacket have been newly introduced. From applications to retrofit design it is known that two methods are easy to apply in retrofit design and the DCM procedure underestimates the target displacement to compare with the DDM procedure.

군항공기사고조사의 전문성과 독립성을 제고하기 위하여 상설사고조사기구를 신설하여야 한다. 상설조사기구를 신설함으로써 조사기구의 위상을 높이고 조사의 신뢰성을 확보할 수 있다. 민과 군이 모두 관련된 사고조사시 민과 군의 조사권한의 주제, 업무협조 등에 관한 규율이 부재하고 있으므로 이를 입법화해야 한다. 군과 관련된 민항공기 사고조사시 군의 전문가들이 참여함이 바람직하다. 조사의 실효성 보장을 위하여 항공사고에 대한 정보를 직접 수집하는 조사관의 활동을 보장하는 규정을 마련해야 한다. 또한, 사고조사의 목적은 오직 사고예방에만 있으므로 정보의 공개범위를 제한하고 조사결과를 형사절차나 징계절차에서 사용할 수 없도록 하여 조사의 객관성을 확보해야 할 것이다.

This paper presents the wind excited acceleration responses of a 50 m guyed mast under the action of Typhoon Dujuan. The response of the structure is reconstructed from using a full finite element model and an equivalent beam-column model. The wind load is modelled based on the measured wind speed and recommendations for high-rise structures. The nonlinear time response analysis is conducted using the Newton Raphson iteration procedure. Comparative studies on the measured and computed frequencies and acceleration responses show that the torsional vibration of the structure is significant particularly in the higher vibration modes after the first few bending modes. The equivalent model, in general, gives less accurate amplitude predictions than the full model because of the omission of torsional stiffness of the mast in the vibration analysis, but the root-mean-square value is close to the measured value in general with an error of less than 10%.

Pursuant to Article 109(1) of the Attorney-at-Law Act of Korea, a person, not an attorney-at-law, who receives or promises to receive money, articles, entertainment or other benefits or who gives or promises to give those things to a third party, in compensation for providing or mediating legal services, such as examination, representation, arbitration(emphasis added), settlement, solicitation, legal consultation, making of legal documents, etc. shall be punished by imprisonment with prison labor for not more than 7 years or by a fine not exceeding KRW 50 million or may be punished by both and there is no specific provision on qualification of arbitrator except on nationality of an arbitrator in the Arbitration Act of Korea. Then, the question arises, can any non-lawyer arbitrator who receives arbitrator's fees be punished in accordance with the Attorney-at-Law Act in Korea? To search for an answer for this matter, this paper examines the Arbitration Act or the Civil Procedure Code of 33 major countries in the world and explains a research on the participation ratio of non-lawyer arbitrators in all 360 arbitration cases registered in 2012 at the Korean Commercial Arbitration Board (KCAB).

All over the country tries to clarify the content of 'Public Policy' in recognition and implementation of Foreign Arbitral Awards : it makes comments of the international consensus of Geneva Convention(1927), New York Convention(1958) and the UNCITRAL Model Law on Public Policy, and it takes a general view of domestic laws how they deal with Public policy and Foreign Arbitral Awards. Foreign Arbitral Awards should be appropriately respected and implementation by the courts of countries encourage parties in a legal procedure to refuse enforcement by invoking "Public Policy." In order to cope with such invocations, the purport of the above recommendation on Foreign Arbitral Awards should be internationally recognized and the exceptional circumstances should be restricted unless the International Court of Arbitral Awards is not established a Dr. Holtzmann/Schwebel brought forward. In this paper suggests the list of the exceptional circumstances. Korean Arbitration Law stipulates as the Civil proceeding Law did, "good morals and the social order of the Republic of Korea" as a ground for refusing enforcement of Arbitral Awards. Studies on counteraction against invocations of Public Policy to refuse enforcement of Foreign Arbitral Awards should be developed.

In this study, the bifurcation analysis of functionally graded material is done using exponential volume fraction law. Shell theory of Love is used for vibration of shell. The Galerkin's method is applied for the formation of three equations in eigen value form. This eigen form gives the frequencies using the computer software MATLAB. The variations of natural frequencies (Hz) for Type-I and Type-II functionally graded cylindrical shells are plotted for exponential volume fraction law. The behavior of exponent of volume fraction law is seen for three different values. Moreover, the frequency variations of Type-I and -II clamped simply supported FG cylindrical shell with different positions of ring supports against the circumferential wave number are investigated. The procedure adopted here enables to study vibration for any boundary condition but for brevity, numerical results for a cylindrical shell with clamped simply supported edge condition are obtained and their analysis with regard various physical parameters is done.
