Feature based design approach is widely studied for the application of mechanical part design and process planning. Mechanical parts are associated with volumetric form features in nature. Therfore, one of the important characteristics that reside in the form feature research until now is that features have been studied in connection with CAPP for material removal. We studied the application of feature based design for ship structure design. Ship structure has interesting nature that tis distinct from mechanical parts. Among these are multiple cell structure, non-volumetric part and production by welding or assembling. An idea of applying feature based design paradigm for design, process planning, cost analysis and engineering calculation was shown. Non-manifold geometric modeler ACIS was adopted to fully benefit from the non-manifold nature of ship structure.

As a key reinforcement connection between a tower and a substructure in offshore wind turbine system, the transition piece is inevitably subjected to cyclic dynamic environmental loads such as wind, current and wave. Therefore, well designed transition piece with high strength and good fatigue resistance is of great significance to the structural safety and reliability of offshore wind power systems. In this study, the structural behavior of the transition piece was studied by an extensive sets of finite element analyses. Three widely used types of transition piece were considered. The characteristics of stress development, fatigue life and weight depending on the type of the transition piece were investigated in the ultimate limit state (ULS) and the fatigue limit state (FLS) of a 5-MW offshore wind turbine to be placed in Korea. An optimal form of the transition piece was proposed based on this parametric study.

The purpose of this paper is a study on the dome plan of S. M. del Fiore Church of F. Brunelleschi. The results of study are as follows: 1. The planning of floor, elevation and cross section plan of S. M. del Fiore church is basically planned by each other correlation. In particular, the octangular form of geometrical standard which is formed with altar as the center at the crossing part is important component elements which is decided by not only the dome, but form and size of the drum and floor plan form of the lantern 2. The dome which has been planned by F. Brunelleshi has completed the new dome, preserving gothic thought intended by the church plan after study on architecture of ancient Rome with Pantheon. And the dome which is a main space of church through all aspects of plan, structure, function and construction about the dome is a opportunity in the beginning of Renaissance architecture which is a new epoch and a turning point of architecture on various point of view. 3. The dome which is constructed by F. Brunelleshi has been planned through the innovative solution by the refusal of traditional semicircle form dome, centering use and creation double-shell structure form for the first time in history. And the construction of dome has been solved with the invention of various construction equipments and machineries, the stone rib planned for connection and reinforcement about shells of the octangular form, the support method for reduction the gravity of bricklayers work and the brick work of nock-patterned shape which is masonry construction method of the architecture of ancient Rome.

When using the light-weight form with polystyrene on slab, as a result of reducing the weight of slab, the span was increased or size of supporting member for slab was decreased. But capacity of punching shear resistance on the slab using the polystyrene form with plat plate system was deteriorated at critical section around the column. But standard for estimate of internal force did not exist, and established study was insufficient. This study performed the experiment on the punching shear for understanding punching shear force at the slab-column connection using the slab with polystyrene form. The principal variable was size of column, arrangement of polystyrene form and existence of shear reinforcement, and we planned four specimens. From the test, we analysed the crack, failure mode, road-displacement graph and punching shear strength, and capacity of punching shear resistance for slab using the polystyrene form was understood.

Although the Java bytecode has numerous advantages, it also has certain shortcomings such as its slow execution speed and difficulty of analysis. In order to overcome such disadvantages, a bytecode analysis and optimization must be performed. The control flow of the bytecode should be analyzed; next, information is required regarding where the variables are defined and used to conduct a dataflow analysis and optimization. There may be cases where variables with an identical name contain different values at different locations during execution, according to the value assigned to a given variable in each location. Therefore, in order to statically determine the value and type, the variables must be separated according to allocation. In order to achieve this, variables can be expressed using a static single assignment form. After transformation into a static single assignment form, the type information of each node expressed by each variable and expression must be configured to perform a static analysis and optimization. Based on the basic type information, this paper proposes a method for finding the related equivalent nodes, setting nodes with strong connection components, and efficiently assigning each node type.

This study examined the aesthetic characteristics of Grecian style which is being considered as the representative classic of Western fashion and the transformations of those Grecian styles on the fashion of the twentieth century. This study used positive research method using literatures on art history and clothing history, fashion related publications, and magazines and websites to understand the trend of fashion designer's collections. The study results are as follows. The aesthetic characteristics of Grecian style was considered to be the ideal beauty combined with symmetry, the functional beauty combined with non-construction, and the sensual beauty combined with natural body. The ideal beauty combined with symmetry appears as a style that shows idealistic proportion of a body emphasizing high-waist based on the golden ratio and the body as a whole rather than details. The functional beauty combined with non-construction appears as perfect recreation a body in its original and natural form. The clothing takes a form that does not have any structural design and has simplified cutting and sewing. It uses pins and strings to fix up the form of clothing which is flexible and naturally draped. The sensual beauty combined with natural body is found in natural silhouette dress alluding naked body in connection with Rousseau' naturalism in neoclassic period. Throughout the twentieth century, the desire for Grecian style was conveyed by a single detail or through an array of allusive effects.

The comtemporary architecture has not an discourse on form and representative style, but a new architectural concept of the generative process through the various relationship of the urban context, the continuity of the time and the experience of the people. This architectureal concepts make new and various architectural attempts to have a virtuality. The viruality is a reality to coexist with the present in contemporary philosophy. Daniel libeskind makes various arhcitectural experimentative attempts to reveal his virtuality through his memory as the Jews and his unconscious virtuality. The 'line' has the connotation of architectural reality and virtuality. Every line drawn becomes architectural form for example, walls, windows and makes spaces, and reveal a boundary as a connection. Architecture's visibility understates and structures its invisible aspect, so that the visible and the invisible make the architecture together. Daniel libeskind maks the virtual lines having the invisible of unconsious, time, and place. He no longer divide the form of architecture, its spatiality from all the implications which it adresses beyond its own particular built time and place and public unconsious mind. He demands the 'virtual line' that remembers distress and the past and reveal the virtuality of time and place. The virtual line is the sentimental communication of architecture.

Urban scape of Gyeongju is overlapped by periods. So, a study of each Periodical urban scape is required to understanding the present urban scape. All it requires study is on account of different a characteristic and the meaning of the scape. Especially, unified Silla period was most flourished in all time, has Abundant image of urban scape, heavily influences present urban scape. The research was proceeded through the classifying the concept of Urban form and the basic ideology and adopting the representative landscape at that time with the literatures and maps, on Unified Silla Period. And then tried to find out the identity of landscape with the link between the concepts of the representative landscape and that of Urban form in chronological order. The identity of historical landscape in Gyeongju on Unified Silla Period from the result of research has been influenced on by the connection with natural environment, urban form revealed by grid, space organized by vigorously heading up the inside, and Buddhistic ideology and esthetics.
