20세기 이후 산업화한 소비사회에서 생산된 기성품들은 '파운드 오브제 (Found object)'라는 새로운 소재로 미술작가들에게 채택되어 작품 속에서 넓은 의미로 재해석 되고 있다. 이를 활용해서 새로운 의미를 부여하는 방법은 표현양식뿐만 아니라 개념적으로도 확장된 새로운 패러다임을 생성한다. 현대미술에서 최초로 파운드 오브제가 사용된 1912년 파블로 피카소(Pablo Picasso)의 이후 다다이즘과 초현실주의, 그리고 팝아트를 통해서 파운드 오브제의 전개를 파악하고 20세기 후반 파운드 오브제의 표현에 대해서 알아본다. 본 연구에서는 파운드 오브제가 작품에서 혼합된 방식에 따라서 '가공되지 않은 오브제', '변용된 오브제', 그리고 '차용된 오브제', 등 3가지 유형으로 구분하여 작가와 작품을 분석한다. 본 연구를 통해서 파운드 오브제를 융복합한 작품은 대상을 물질적으로 발전시킬 뿐만 아니라 미술의 전통적 규범에서 벗어나 자유로운 개념의 미술을 실천할 수 있도록 한다는 점에 주목한다.

The modern architecture has to find more essential configuration order rather than the spatial order in the reasonable feint. In other side, paintings and sculptures as a part of the building in the past become a pure art and develop an abstract art. Also they make many affects on the modern architecture as a paradigm. New material has brought to the new forms and the changes of the overall culture and art. One of the new changes has made the object that is one of unique culture symptoms in the 20C and the general part of the modem art includes it. The wall that limits the inside area through mass and volume before the recent times had treated as the object to express the special mean and character. However, the wall has developed as a component that consists of the internal space through surface and volume rather than mass or structure since the recent times. Now, I survey the objective tendency of the wall in the modem interior architecture mainly focused on the relation between object in the abstract art and wall inside.

As a product structure or BOM(bill of material) of products is hierarchically structured, the design based on the concept of relational data base modeling causes low performances in data search or processing. For this reason, an object-oriented approach to designing a product structure is proposed in this paper. Using Rumbaugh's OMT (Object Modeling Technique) method, classes of parts, BOM structure, options, and models are defined and their class-relationship diagrams are proposed. For the representation of the BOM structure suitable for the object-oriented paradigm, a new data architecture called the BOM item class is suggested. It is expected that the proposed data structure ensures better reusability and expandability due to the modularity.

Subsea structures are always vulnerable to accidental risks induced by fishing gear, dropped objects, etc. This paper presents the design of a subsea manifold protective structure that protects against dropped object impacts. Probable dropped object scenarios were established considering the shapes and masses of the dropped objects. A design layout for the manifold protective structure was proposed, with detailed scantlings and material specifications. A method applicable to the pipelines specified in DNV-RP-F107(DNV, 2010) was applied to calculate the annual probabilities of dropped objects hitting the subsea manifold. Nonlinear finite element analyses provided the structural consequences due to the dropped object impacts such as the maximum deflections of the protective structure and the local fracture occurrences. A user-subroutine to implement the three-dimensional fracture strain surface was used to determine whether local fractures occur. The proposed protective structure was shown to withstand the dropped object impact loads in terms of the maximum deflections, even though local fractures could induce accelerated corrosion.

To put it simply, thing theory is a study of meaningful capacities of materiality. Although T. S. Eliot regarded pathetic fallacy as the bad example of objective correlatives in his modernism poetry theory, it is clear that many objects in literary works reflect diverse human desires. Among many, Victorian sensation novels are the most distinct genre where the various paraphernalia in them indicate the distorted and exaggerated greed of the industrial revolution era. Whereas the male protagonists are usually related with the norms objects of authority such as portrait and locket, the female characters' connection with cosmetics and white dress shows their oppressed and fragile position in the patriarchal and hierarchical society. In the (post)modern society, the ambiguity of things has grown rapidly due to the increasing discrepancy between objects and things. In special, the new journalism and the psychological realism novels often reveal the post-truth phenomenon because consumerized audience depend more upon the attraction and affect than the mere evidence and facts. For the individual, according to object relations theory, these alternative facts are rather internalized into their mind as the internal object when they are motivated by the non/contact with primary caregivers in their childhood. The dominant material imagery in (post)modern fiction becomes the site of resistance because of their reconstructed and extended meaning. The object relations theory and thing theory can be effectively used to uncover the complicated meanings of desired objects by using the human-object's meaningful relations and early mental images that are secretly alive still in the present.

Current geometric modeling and analysis are commonly based on B-Rep modeling and a finite elements method respectively. Furthermore, it is difficult to represent an object whose material property is heterogeneous using the B-Rep method because the B-Rep is basically used for homogeneous models. In addition, meshes are required to analyze a property of a model when the finite elements method is applied. However, the process of generating meshes from B-Rep is cumbersome and sometimes difficult especially when the model is deformed as time goes by because the topology of deforming meshes are changed. To overcome those problems in modeling and analysis including homogeneous and heterogeneous materials, we suggest a unified modeling and analysis method based on implicit representation of the model using R-function which is suggested by Rvachev. For implicit modeling of an object a distance field is approximated and blended for a complex object. Using the implicit function mesh-free analysis is possible where meshes are not necessary. Generally mesh-free analysis requires heavy computational cost compared to a finite elements method. To improve the computing time of function evaluation, we utilize GPU programming. Finally, we give an example of a simple pipe design problem and show modeling and analysis process using our unified modeling and analysis method.

We discuss development of a simulator for automated manufacturing systems (AMSs) which have sophisticated automated material handling equipments and complicated work flows. The simulator is designed to satisfy the following requirements. A user should be able to easily configure or specify an AMS through a graphical user interface (GUI) and minimal data input. The user should be able to model diverse and complied control logic for automated material handling systems like automated guided vehicle (AGV) systems, robot workcell systems and conveyor systems as well as complicated job flow program. Real time animation is desired. Finally, the simulator should be easily maintained and extended. To satisfy the requirements, we use an object-oriented paradigm for modeling, designing, and programming of the simulator. We use an object-oriented modeling framework to design the modeling elements library, and take the process interaction approach for scheduling processes and events. To model a user-defined diverse control logic, we also develop a script language and its interpreter. We explain design and implementation strategies. We implement the simulator using Visual C++ 4.2 and Open GL on Windows NT and the Windows95. Some modeling examples will be demonstrated.

This study examines shear capacity performance and structural characteristics of reinforced concrete beam using carbon fiber sheet(CFS), g)ass fiber sheet(GFS), glass fiber steel plate(GSP) and carbon fiber bar CB) which are reinforcing materials for reinforced concrete beam in order to produce similar condition to repair and reinforce actual structure and aims to provide data available In designing and constructing reinforced concrete structures under the structural damage. This study obtains the following conclusions. After considering the shear experiment results. it was indicated that the CB reinforced test object was the best in the shear capacity improvement and ductility capacity as it was contained in the concrete and was all operated, Also, GFS reinforced test object indicated the reduced flexural capacity but good shear capacity. GSP reinforced test object had bigger reinforcing strength than other reinforcing test objects. On the other hand, it showed the lowest reinforcement effect as compared section thickness of reinforced material because it showed the bigger relativity a section thickness of reinforced material. If the adherence to the concrete is improved, it will seem to show bigger reinforcement effect.
