커뮤니케이션학에서 통약가능한 이론적 대중매체체계론이 부재하다는 점은 비교연구를 비롯한 경험연구에서 난점으로 남아있었다. 본 연구는 하버마스의 2단계 사회론을 수정한 수정된 2단계 사회론을 바탕으로 정적 일반대중매체체계론을, 루만의 경계이론과 들뢰즈 가타리의 배치이론을 종합한 경계배치이론을 바탕으로 동적 일반대중매체체계론을 제안한다. 정적 일반대중매체체계론에서 대중매체체계는 일반화된 언어를 조정매체로 하는 문화체계의 하위사회체계로서 여타 하위사회체계 및 생활세계와 상호침투한다. 동적 일반대중매체체계론에서 대중매체체계는 다른 모든 하위사회체계의 경계로서 하위사회체계의 자기관계적 관찰을 생활세계에 의한 타자관계적 관찰과 접목시킨다. 또 대중매체체계는 체계와 생활세계 간의 상호침투를 매개한다. 특히 대중매체체계에서의 수행은 체계를 생활세계로 탈영토화하고 생활세계를 체계로 재영토화한다. 일반대중매체체계론은 다양한 경험적 대중매체체계론에 통약가능성을 제공해주고 편향되게 연구대상을 설정하지 않도록 도움을 줄 것으로 기대된다.

천인관계론은 한대에 매우 성행하던 학술이론이었다고 할 수 있으며, 서한시기의 동중서가 이러한 이론을 체계화하고 널리 알리는데 중요한 역할을 했다고 하기도 한다. 동중서의 천인관계론에서는 인간에게 속하는 각종의 특징들이 자연계 안에 투사되어 천과 자연을 의인화시켜서 천과 인간이 서로 같은 구조를 가지고 있으며 비슷한 기능을 나타낸다고 했다. 왕충의 천인관계론은 바로 서한시기에 유행했던 천인감응론의 이론적 근거를 비판할 뿐만 아니라, 그 자신의 전체 사상체계의 기초가 된다고 할 수 있는 것이다. 왕충이 재세했던 당시에 유행했던 사회적 의식형태는 이미 변형된 모습의 천인감응론이었다고 할 수 있는데, 왕충은 이러한 형태의 천인감응론은 허망한 것이라고 생각했기 때문에 매우 신랄하게 비판을 한다. 왕충의 비판은 두 가지 다른 측면에서 진행되었는데, 하나는 천인감응론에 대하여 인간의 경험적 사실의 입장에서 그것의 진위를 판단하는 것이었고, 다른 하나는 천인감응론이 인간과 사회의 가치 의미적 측면에서 가치취향의 옳고 그름을 판단하는 것이었다. 이와 같은 서로 다른 함의는 왕충의 비판 작업 속에서 항상 중첩되어 나타나거나 동시에 나타나기도 한다. 이러한 왕충의 천인관계론에 대하여 본문에서는 왕충이 비판한 천인감응론과 천인감응론의 비판을 통한 인간존재의 의미를 중심으로 논의를 진행해 보도록 하겠다.

"Sibeongron(時病論)" is a book that was written by Noepung(雷豐, Leifeng) in the latter period of Cheong(淸) dynasty. In this book, Noepung described the Siryeong(時令) disease by oegam(外感), and the theoretical tool he used to analyze the Siryeong disease was the Ungi(運氣) theory based on "Naegyeong(內經)". Based on the Ungi theory, Noepung(雷豐) classified the Siryeong(時令) disease into two groups of singam(新感) and bokgi(伏氣), so that his theory of Siryeong disease could successfully describe the Siryeong diseases of four seasons. To understand his theory of Siryeong disease, it is very important to understand the concept of the relation between the division of time and the etiological cause by oegam(外感). Based on this concept, this study will be analyzing how each Siryeong disease was defined in his etilogical view which had been originated from the Ungi(運氣) theory in "Naegyeong".

It has been known that one-dimensional rod theory is very effective as a simplified analytical approach to large scale or complicated structures such as high-rise buildings, in preliminary design stages. It replaces an original structure by a one-dimensional rod which has an equivalent stiffness in terms of global properties. If the structure is composed of distinct constituents of different stiffness such as coupled walls with opening, structural behavior is significantly governed by the local variation of stiffness. This paper proposes an extended version of the rod theory which accounts for the two-dimensional local variation of structural stiffness; viz, variation in the transverse direction as well as longitudinal stiffness distribution. The governing equation for the two-dimensional rod theory is formulated from Hamilton's principle by making use of a displacement function which satisfies continuity conditions across the boundary between the distinct structural components in the transverse direction. Validity of the proposed theory is confirmed by comparison with numerical results of computational tools in the cases of static, free vibration and forced vibration problems for various structures.

Single- and multi-span orthotropic functionally graded hollow cylinders subjected to axisymmetrical bending are investigated on the basis of a unified shear deformable shell theory, in which the transverse displacement is expressed by means of a general shape function. To approach the through-thickness inhomogeneity of the hollow cylinder, a laminated model is employed. The shape function therefore shall be determined for each fictitious layer. To improve the computational efficiency, we resort to a transfer matrix method. Based on the principle of minimum potential energy, equilibrium equations are established, which are then solved analytically using the transfer matrix method for arbitrary boundary conditions. Numerical comparisons among a third-order shear deformable shell theory, an exact elastic theory and the present theory are provided for a simply supported hollow cylinder, from which the present theory turns out to be superior in stress estimation. Distributions of displacements and stresses in single- and three-span hollow cylinders with different boundary conditions are also illustrated in numerical examples.

The novelty of this paper is the use of trigonometric four variable plate theory for free vibration analysis of laminated rectangular plate supporting a localized patch mass. By dividing the transverse displacement into bending and shear parts, the number of unknowns and governing equations of the present theory is reduced, and hence, makes it simple to use. The Hamilton's Principle, using trigonometric shear deformation theory, is applied to simply support rectangular plates. Numerical examples are presented to show the effects of geometrical parameters such as aspect ratio of the plate, size and location of the patch mass on natural frequencies of laminated composite plates. It can be concluded that the proposed theory is accurate and simple in solving the free vibration behavior of laminated rectangular plate supporting a localized patch mass.

It has been recognized, virtually from the time of its inception, that fisheries economics, like other aspects of resource economics, should ideally be cast in capital-theoretic terms. The fish population or biomass can be viewed as a capital stock in that, like conventional or man-made capital, it is capable of yielding a sustainable consumption flow through time. This study is to introduce the optimal control theory which was extended from the theory of calculus of variations into the study of former static theory of fisheries economics started by Gordon (1954). The optimal control theory eliminated the inadequacies of the classical techniques to a large extent. From this point of view, this study, on the base of Schaefer model, summerizes most of major results achieved so far, but does so in a manner such that the links with capital theory are made transparent. This study explores two sets of problems. The first concerns the optimal approach to the equilibrium stock, i.e. the optimal investment policy. The second set of problems arises from the relaxation of the highly restrictive assumption of autonomy (i.e. the assumption that the parameters are independent of time), then concludes the relaxation of linearity assumption together with the complexities caused by that.

The purpose of this study was to get a possibility of maintenance architecture, which present instead of contemporary architecture through interrelation between Organic architecture and Gaia theory. Through this study to fine a interrelation part between Organic architecture and Gaia Theory as general case, and through the Gaia theory, Organic architecture being progress as new design experiment exposition. After modern time, we can have presentation of main subject which corresponds to mechanical rationalism and rising Organic architecture from Organic Holism. Organic architecture is get close to biological or ecological access to nature and environment so from and inner order could apply to architecture after that better circumstances and maintenance(sustain architecture) development could possible, although the point became more importance. In this point, Jim E. Lovelock's Gagia theory which try to proscript relationship(element of enviroment) of earth, this is pretty big deal and we can find a connection with Organic architecture in the theory.

Hill's anisotropy theory and isotropy theory under the deformed profile assumed two separate cases(that is circular and ellipitical) are applied to predict the plastic deformation characteristics of bulge, the strain and polar height under instability condition, using thin square diaphragms of stainless steel, mild steel, brass, copper and aluminum. In this study it was found that the pressure-polar height curves, and the polar height-the polar radius of curvature curve, under anisotropy theory and isotropy theory, assuming a circle profile, agree well with the experimental results, and the equivalent strains of the instability condition under anisotropy theory are better good agreement with the experimental results than those of the instability condition under isotropy theory. Beside, FLCo(plane Strain Intercept) obtained by Bethlehem FLC method and standard FLC method (modified) agree well with the experimental result.

In this paper a new eight-unknown higher order shear deformation theory is proposed for functionally graded (FG) material plates. The theory based on full twelve-unknown higher order shear deformation theory, simultaneously satisfy zeros transverse stresses at top and bottom surface of FG plates. Equations of motion are derived from principle of virtual displacement. Exact closed-form solutions are obtained for simply supported rectangular FG plates under uniform loading. The accuracy of present numerical results has been verified by comparing it with generalized shear deformation theory. The effect of power law index of functionally graded material, side-to-thickness ratio, and aspect ratio on static behavior of FG plates is investigated.
