중국에서 영화 산업이 발전함에 따라 영화포스터의 종류가 다양화되고 있다. 그 중에서 '콘셉트 포스터'는 홍보 초기 단계에서 영화에 대한 첫인상을 형성하는데 중요한 역할을 하고 있어 영화 홍보에 있어서 그 가치를 인정받고 있다. 하지만 중국에서는 아직까지 창의성을 인정받고 있는 영화 포스터가 많지 않기 때문에 콘셉트 포스터의 창작에 있어서 함축적 이미지 구상과 독창적 표현방식에 대한 연구가 필요하다. 따라서 본 연구는 상업성뿐만 아니라 예술성을 인정받고 있는 황해의 콘셉트 포스터에 나타난 시각적 표현방법을 분석함으로써 중국 콘셉트 포스터의 예술적 가능성에 대해 살펴보았다. 연구 결과 황해는 영화의 주요 장면이나 유명한 배우의 이미지를 활용하는 것을 지양하고 영화의 주제를 함축적으로 담아낼 수 있는 이미지를 구상한 것으로 나타났다. 미니멀리즘, 색채, 타이포그래피, 회화적 이미지를 활용해 영화의 주제를 함축적으로 담아낼 수 있는 이미지를 구상해 표현하는 것으로 나타났다. 본 연구 결과는 중국 영화포스터 디자인을 제고하는데 기초적인 자료를 제공한다는데 의의가 있다.

A coupled recursive total least squares (CRTLS) algorithm is proposed for parameter estimation of permanent magnet synchronous machines (PMSMs). TLS considers the errors of both input variables and output ones, and thus achieves more accurate estimates than standard least squares method does. The proposed algorithm consists of two recursive total least squares (RTLS) algorithms for the d-axis subsystem and q-axis subsystem respectively. The incremental singular value decomposition (SVD) for the RTLS obtained by an approximate calculation with less computation. The performance of the CRTLS is demonstrated by simulation and experimental results.

Objective & Method : We investigated the identity of tri-energizer, which was originally described in Huang Di Nei Jing and claimed by traditional scholars, and drew the following conclusions. Result & Conclusion : According to Huang Di Nei Jing tri-energizer is one of the six hollow-organs and is called hollow organs for digestion and elimination, water guffer organ, or solitary hollow organ. It is believed that tri-energizer is regarded as the existing entity based on following several different sources; it functions as the course of channels, regulates wind and link and physiological function-especially intrinsic function of upper, middle, lower internal organs. It also controls syndromes and dysfunction of an illness, the surface of the body, and the cracked surface of the skin. Finally, bold and timidity depend on the tri-energizer. Experts determined the true nature of tri-energizer types. Experts include: Yu Tuan from the Ming dynasty, Tang Jong Hai and Ye Lin from the Qing dynasty, and Zhang Xi Chun from the Zhunghua Minguo period. These experts' claims are based on shape and forms of tri-energizer. Our examinations of anatomical and physiological basis on tri-energizers showed that, in a narrow sense, tri-energizer indicates visceral and parietal peritoneum and omentum surrounding the internal organs, and in a broad sense, indicates the overall membrane wrapping around the whole internal organs including five visceral organs and six hollow organs.

In this paper, we introduce some approximate optimal solutions and an augmented Lagrangian function in nonlinear programming, establish dual function and dual problem based on the augmented Lagrangian function, discuss the relationship between the approximate optimal solutions of augmented Lagrangian problem and that of primal problem, obtain approximate KKT necessary optimality condition of the augmented Lagrangian problem, prove that the approximate stationary points of augmented Lagrangian problem converge to that of the original problem. Our results improve and generalize some known results.

A mechanics model is developed in this paper for concrete-filled steel CHS (circular hollow section) beam-columns. A unified theory is described where a confinement factor (${\xi}$) is introduced to describe the composite action between the steel tube and the filled concrete. The predicted load versus deformation relationship is in good agreement with test results. The theoretical model was used to investigate the influence of important parameters that determine the ultimate strength of concrete-filled steel CHS beam-columns. The parametric and experimental studies provide information for the development of formulas for the calculation of the ultimate strength of the composite beam-columns. Comparisons are made with predicted beam-columns strengths using the existing codes, such as LRFD-AISC-1999, AIJ-1997, BS5400-1979 and EC4-1994.

This paper investigates the structural responses of axially restrained steel beams under fire conditions by a nonlinear finite element method. The axial restraint is represented by a linear elastic spring. Different parameters which include beam slenderness ratio, external load level and axial restraint ratio are investigated. The process of forming a mid-span plastic hinge at the mid-span under a rising temperature is studied. In line with forming a fully plastic hinge at mid-span, the response of a restrained beam under rising temperature can be divided into three stages, viz. no plastic hinge, hinge forming and rotating, and catenary action stage. During catenary action stage, the axial restraint pulls the heated beam and prevents it from failing. This study introduces definitions of beam limiting temperature $T_{lim}$, catenary temperature $T_{ctn}$ and warning time $t_{wn}$. Influences of slenderness ratio, load level and axial restraint ratio on $T_{lim}$, $T_{ctn}$ and $t_{wn}$ are examined.
